Double-sided compound chamfering cutter

Abstract

This utility model relates to a double-sided composite chamfering tool. Traditional deburring processes involve first machining one side of a stepped hole with a chamfering tool. To machine the other side, the workpiece needs to be flipped, and different chamfering tools need to be switched, increasing processing difficulty and reducing efficiency. This utility model includes an integrated chamfering tool holder. The integrated chamfering tool holder is characterized by an upper chamfering cutter disc, with upper rounded corner inserts evenly spaced on the outer circumference of the upper chamfering cutter disc. A lower chamfering cutter disc is symmetrically positioned at the outer end of the integrated chamfering tool holder relative to the upper chamfering cutter disc, and lower rounded corner inserts are mounted on the lower chamfering cutter disc. This utility model, by setting a lower chamfering cutter disc on the integrated chamfering tool holder corresponding to the upper chamfering cutter disc and correspondingly setting multiple rounded corner inserts, facilitates chamfering on both sides of the workpiece. This reduces processing difficulty and improves processing efficiency.

Description

Technical Field

[0001] This utility model relates to the field of parts processing technology, and in particular to a double-sided composite chamfering tool. Background Technology

[0002] The existing technology for chamfering workpieces is as follows: when the direction of the tool movement is consistent with the feed direction of the workpiece, the workpiece is chamfered; when the direction of the tool movement is inconsistent with the feed direction of the workpiece, the workpiece needs to be chamfered in a different direction.

[0003] The traditional deburring process involves first machining one side of the stepped hole with a chamfering tool. When machining the other side, the workpiece needs to be flipped over, and different chamfering tools need to be switched before machining the other side of the stepped hole. When the diameter of the chamfer on the end face of the stepped hole is different, different specifications of chamfering tools also need to be changed, which increases the processing difficulty and reduces the processing efficiency. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a double-sided composite chamfering tool that can reduce processing difficulty and improve processing efficiency.

[0005] Therefore, the present invention adopts the following technical solution: a double-sided composite chamfering cutter, comprising an integral chamfering cutter bar, characterized in that an upper chamfering cutter disc is provided on the integral chamfering cutter bar, upper rounded corner blades are evenly spaced on the outer periphery of the upper chamfering cutter disc, a lower chamfering cutter disc is symmetrically provided at the outer end of the integral chamfering cutter bar relative to the upper chamfering cutter disc, and a lower rounded corner blade is provided on the lower chamfering cutter disc.

[0006] Preferably, the upper and lower chamfering cutter heads are provided with three blade positioning grooves evenly spaced on their outer periphery, and the center of the blade positioning seat is provided with a rounded blade and fixed by a blade screw.

[0007] Preferably, the chamfering tool holder has a positioning groove on the center tool holder at its outer end, and a torque transmission key is installed in the positioning groove. The torque transmission key is fixed to the center tool holder by a positioning key screw and is used to transmit the cutting force during the chamfering head machining.

[0008] Preferably, a central spacer is provided between the upper chamfering cutter head and the lower chamfering cutter head.

[0009] Preferably, the locking nut is provided at the outer end of the central cutter bar, and multiple spacer pads are evenly spaced between the locking nut and the lower chamfering cutter disc.

[0010] Preferably, the spacer includes 2mm spacer and 3mm spacer, with different specifications of spacer corresponding to different part thicknesses during processing.

[0011] The beneficial effects of this utility model are as follows: 1. By setting a lower chamfering cutter head on the integrated chamfering cutter head corresponding to the upper chamfering cutter head, and setting multiple rounded corner inserts accordingly, it is convenient to perform chamfering processing on both sides of the workpiece.

[0012] 2. The rounded corner inserts are mounted on the insert positioning seat, allowing for easy disassembly and replacement to suit different workpieces. The lower chamfering cutter head can also be detached from the integrated chamfering cutter holder for convenient overall replacement.

[0013] 3. A spacer is installed between the upper and lower chamfering cutter heads. A set of spacers of different thicknesses is installed between the lower chamfering cutter head and the locking nut. This structural design improves the versatility of the cutting tools. Products of corresponding thickness can be processed according to the thickness of the spacer inserted between the upper and lower chamfering cutter heads. Attached Figure Description

[0019] The present invention will be further described below with reference to specific embodiments.

[0020] like Figures 1-2 The illustrated double-sided composite chamfering tool includes an integral chamfering tool holder 1, an upper chamfering tool disc 2 mounted on the integral chamfering tool holder 1, and upper rounded corner inserts 10 evenly spaced on the outer periphery of the upper chamfering tool disc. A lower chamfering tool disc 4 is symmetrically arranged at the outer end of the integral chamfering tool holder 1 relative to the upper chamfering tool disc, and a lower rounded corner insert is mounted on the lower chamfering tool disc 4. The symmetrical arrangement of the upper and lower chamfering tool discs, and the evenly spaced multiple rounded corner inserts on the tool discs, facilitates multi-faceted machining of the workpiece, improves efficiency, and eliminates the need for frequent workpiece repositioning to meet machining requirements.

[0021] Specifically, the upper chamfering cutter head 2 and the lower chamfering cutter head 4 are evenly spaced around their outer periphery with three blade positioning seats 11. A rounded blade 10 is positioned at the center of each blade positioning seat 11 and is fixed by a blade screw 9. The blade is fixed in the center by the screw, ensuring stable and reliable positioning. It can also be easily disassembled and replaced, which not only meets the processing requirements of different product specifications but also ensures the processing quality of the tool.

[0022] like Figures 3-4 As shown, specifically, a positioning groove 14 is provided on the center tool 15 at the outer end of the chamfering tool holder. A torque transmission key 3 is installed in the positioning groove 14. The torque transmission key 3 is fixed to the center tool holder by a positioning key screw 16. The top of the torque transmission key 3 passes through multiple spacers and the notch 12 of the upper chamfering tool head. It is used to transmit the cutting force during the machining of the lower chamfering tool head.

[0023] Specifically, a central spacer 8 is provided between the upper chamfering cutter head 2 and the lower chamfering cutter head 4. The central spacer 8 is 2mm thick and serves to control the distance between the upper and lower chamfers.

[0024] Specifically, the locking nut 6 is provided at the outer end of the central cutter bar 15, and multiple spacer pads are evenly spaced between the locking nut 6 and the lower chamfered cutter disc 4. Spacer grooves are formed on the central cutter bar, and the multiple spacer pads are installed in the spacer grooves to form a tight fit.

[0025] Specifically, the spacers include 2mm spacers 7 and 3mm spacers 5, with different specifications of spacers corresponding to different part thicknesses during processing.

[0026] This invention utilizes a combination design of an upper and lower chamfering cutter head, with correspondingly arranged multiple rounded corner inserts, to facilitate chamfering on both sides of the workpiece. The rounded corner inserts are mounted on insert positioning slots, allowing for easy disassembly and replacement to suit different workpieces. The lower chamfering cutter head can also be detached from the integrated chamfering cutter holder for convenient overall replacement.
