The utility model discloses a machine-clamped PCD pre-milling cutter, which comprises an aluminum alloy tool base and replaceable PCD cutter teeth. The pre-milling cutter base is provided with a groove, and the PCD cutter head is installed in the groove Inside; the central axis of the groove and the central axis of the pre-milling cutter base is provided with an included angle between 0° and 90 degrees; the arc chamfering radius around the groove on the pre-milling cutter base Is smaller than the arc angle radius of the PCD cutter head; two or more of the grooves with different included angles form a subset, and the subset is provided with two or more and arranged in an orderly manner On the base of the pre-milling cutter. The utility model solves the problem that in the processing process of the conventional pre-milling tool, since the cutter teeth cannot be disassembled and replaced, the processing effect is affected after individual teeth are damaged, or the cutter is replaced as a whole, and the repair period is long. The cutter teeth are designed to be replaceable, and a single cutter tooth can be replaced, or the entire group can be replaced, which greatly shortens the tool repair cycle and saves production costs.

Technical field
[0001] This utility model belongs to the technical field of production equipment, and specifically relates to a machine-clamped PCD pre-milling cutter.
Background technique
[0002] At present, the edge banding machine pre-milling cutter used in the furniture industry is mainly used for finishing milling of the surface of the processing board, and then sealing the rubber strip. Because the processed material is mostly veneer particleboard or medium density board, Due to its own characteristics, the tool teeth will inevitably be damaged or broken during the machining process. Cemented carbide tool teeth are easy to blunt, short service life, frequent replacement, and affect processing efficiency. Diamond tools are mostly integrally welded PCD composite blade tools. The blade has high hardness, good wear resistance, and long life, but it is easy to rot the teeth, which affects the processing quality of the plate, and requires overall repair after wear, which takes a long time and high cost. The cutter of the utility model is designed to change this situation. The PCD cutter head is designed as a single replaceable type. The positioning square groove of the base body is closely attached to the positioning surfaces of the PCD cutter head. This tool has high precision, accurate positioning, and can be replaced by a single tooth or a whole group. While continuing the full performance of the integral PCD pre-milling tool in use, by replacing the PCD head, the impact of tool wear on the quality of the plate can be eliminated in a timely and accurate manner. At the same time, the tool can be repaired with single tooth or Multi-tooth or entire group processing, thereby shortening the tool repair cycle. The cutter of the utility model has the characteristics of convenient and quick replacement of the PCD cutter head, accurate positioning, high machining accuracy, long service life and the like in use.
Utility model content
[0003] The purpose of the utility model is to overcome the shortcomings of the prior art, and to provide a pre-milling cutter for edge banding machines by replacing the PCD cutter head.
[0004] The technical solution adopted by the utility model is: a machine-clamped PCD pre-milling cutter, including a pre-milling cutter base and a replaceable PCD cutter head; the pre-milling cutter base is provided with grooves, the The PCD cutter head is installed in the groove; an included angle between 0° and 90° is set between the central axis of the groove and the central axis of the pre-milling cutter base.
[0005] Further, the groove is a square with arc chamfers all around.
[0006] Further, the arc chamfering radius around the groove on the pre-milling cutter base is smaller than the arc corner radius of the PCD cutter head.
[0007] Further, two or more of the grooves with different included angles form a subset, and the subset is provided with two or more and is arranged in an orderly manner on the base of the premilling cutter .
[0008] Further, the PCD cutter head is fastened to the premilling cutter base body by bolts.
[0009] Further, the bolt is fastened obliquely on the premilling cutter base of the PCD cutter head, and the angle between the central axis of the bolt and the positioning surface B and the positioning surface A is between 0° and 10° between.
[0010] Further, the PCD cutter head is formed by welding a matrix and a PCD composite sheet.
[0011] The beneficial effect of the utility model: the PCD cutter head is designed as a single replaceable type, the positioning square groove of the base body is closely attached to each positioning surface of the PCD cutter head, and the screw is fastened, so that the cutter has high precision, The performance of accurate positioning, single tooth or whole group replacement. While continuing the full performance of the integral PCD pre-milling tool in use, by replacing the PCD head, the impact of tool wear on the quality of the plate can be eliminated in a timely and accurate manner. At the same time, the tool can also be repaired with single tooth or Multi-tooth or entire group processing, thereby shortening the tool repair cycle.
