Abstract

The utility model provides a cutter sleeve, and belongs to the technical field of machine tool accessories. The cutter solves the problems that the existing cutter is easy to cause stacking scraps when processing an inner hole of a shaft part to reduce the processing quality of a product and the like. The cutter sleeve comprises a cylindrical body, wherein a threaded hole is formed in the front end of the cylindrical wall in a penetrating manner in the radial direction, a through hole which axially penetrates through the front end face and the rear end face of the body is formed in the cylindrical wall of the body, the through hole and the threaded hole are staggered in the circumferential direction of the body, the front end of the through hole is inserted and fixedly connected with a water outlet seat, a spray pipe which extends forwards is fixedly connected to the water outlet seat, and the spray pipe is communicated with the through hole through the water outlet seat. The cooling liquid is sprayed out from the spray pipe after passing through the through hole and the water outlet seat, so that the chips formed by turning can be washed away, the stacking chips are reduced, and the processing quality of products is improved.

Description

Knife sleeve Technical Field The utility model belongs to the technical field of machine tool accessories, and relates to a cutter sleeve. Background The knife sleeve is a connecting part for connecting the knife and the knife holder. The cutter sleeve is cylindrical, the cutter handle of the cutter is inserted into the cutter sleeve and fixed, the front end of the cutter handle extends out of the cutter sleeve and is fixedly provided with a blade, the cutter sleeve is inserted into the cutter holder and fixed, and the cutter holder is fixed on the cutter holder of the lathe carriage assembly. When turning an inner bore, it is necessary to insert the end of a tool into the inner bore of the product. When the inner hole of the shaft part is machined by turning, particularly in deep hole machining, a general spray head on a lathe cannot spray cooling liquid into the inner hole to cool and remove scraps, the scraps are easily piled up to scratch the part, and the machining quality of a product is reduced. Disclosure of utility model The utility model aims to solve the problems in the prior art, provides a cutter sleeve, and solves the technical problem that the product processing quality is reduced due to the fact that chips are easy to pile when an inner hole of a shaft part is processed by an existing cutter. The aim of the utility model can be achieved by the following technical scheme: The utility model provides a knife pouch, is including being the cylindric body, radially run through on the section of thick bamboo wall of body front end and be provided with the screw hole, its characterized in that, be provided with the through-hole that runs through terminal surface and rear end face before the body along the axial on the section of thick bamboo wall of body, the through-hole staggers the setting in the circumference of body with the screw hole, the front end of through-hole inserts establishes and fixedly connected with play water seat, fixedly connected with stretches out forward the spray tube on the play water seat, spray tube and through play water seat intercommunication. The front end of the cutter handle is fixedly provided with a blade, the cutter handle is inserted into the inner hole of the cutter sleeve body, the front end of the cutter handle extends out of the front end of the cutter sleeve, and the blade and the spray pipe are positioned on the same side of the body. The locking screw is connected in the threaded hole in a threaded manner, and the handle of the cutter is fixed in the cutter sleeve by tightening the locking screw. The tool sleeve is inserted and fixedly connected to the tool apron, and the tool apron is fixedly connected to the tool rest of the lathe carriage assembly. The rear end hole of the through hole on the body is communicated with the spray pipe of the spray system, and the cooling liquid cannot enter the threaded hole due to the fact that the threaded hole and the through hole are staggered in the circumferential direction of the body. When the inner hole of the part is machined by turning, the front end of the cutter handle stretches into the inner hole of the part, cooling liquid is sprayed out of the spray pipe through the through hole and the water outlet seat, and the spray pipe stretches out forwards, so that the cooling liquid can be sprayed into the inner hole of the part forwards at the outlet of the spray pipe, chips formed by turning can be flushed away, cooling and chip removal can be performed, chip stacking is reduced, and the machining quality of products is improved.
