Description

Technical Field

[0001] This utility model relates to a composite chamfering tool, specifically a composite chamfering tool capable of double-sided chamfering, belonging to the field of chamfering tool technology. Background Technology

[0002] A compound chamfering cutter is a tool composed of chamfering inserts with different angles. By combining different inserts, various chamfering processes can be achieved. The characteristics of this type of tool are its versatility and flexibility, enabling it to adapt to diverse machining needs. A compound chamfering cutter typically consists of a tool holder, a tool body, and a cutting edge. The tool holder connects to the machine tool, the tool body supports the cutting edge, and the cutting edge is the part that actually performs the cutting work.

[0003] In the prior art, such as the composite chamfering tool disclosed in CN207255273U, a tool head is provided. The sidewall of the tool head has at least two cutting teeth, each tooth including a first cutting segment and a second cutting segment. The radial profile edge of the first cutting segment extends outward from the end of the tool head to the side edge of the tool head, and the radial profile edge of the second cutting segment extends inward from the side edge of the tool head. The sidewall of the tool head has at least two cutting teeth, each tooth including a first cutting segment and a second cutting segment. The first cutting segment is used to process the upper chamfer. It can process both upper and lower chamfers sequentially without using two different tools, thus eliminating the time spent changing tools and improving processing efficiency; it also reduces the number of tools used and lowers tooling costs.

[0004] Although the above technical solution can process both upper and lower chamfers sequentially without using two different tools, thus eliminating the time spent on tool changing, when the tool movement direction is inconsistent with the feed direction of the part, the part can only be chamfered in reverse direction. Therefore, processing such parts is cumbersome and affects the efficiency of the workers. In view of this, a composite chamfering tool capable of double-sided chamfering is provided to overcome the above defects. Utility Model Content

[0005] This invention provides a composite chamfering tool capable of double-sided chamfering to address the problem that when the direction of the cutting tool's movement is inconsistent with the feed direction of the part, the part can only be chamfered in a different direction, resulting in cumbersome processing steps and reduced efficiency for workers.

[0006] The present invention achieves the above objectives through the following technical solution: a composite chamfering tool capable of double-sided chamfering, comprising a fixed tool holder, wherein the front end of the fixed tool holder is provided with a chamfering mechanism for chamfering the workpiece, and the outer surface of the fixed tool holder is provided with a cooling mechanism for cooling the tool.

[0007] The chamfering mechanism includes a mounting rod, which is fixed to the front end of a fixed tool holder. A first chamfering tool is mounted on one end of the mounting rod, and a second chamfering tool is mounted on the outer surface of the mounting rod. The outer walls of both the first and second chamfering tools are fitted with fixing screws that abut against and connect with the outer wall of the mounting rod.

[0008] As a further improvement of this utility model: the inner walls of the first chamfering blade and the second chamfering blade are both fixed with limiting blocks, and one side of the limiting block is slidably connected to a limiting groove opened on the mounting rod.

[0009] As a further improvement of this utility model: the cooling mechanism includes a mounting shell, which is placed on the outer surface of the fixed knife handle.

[0010] As a further improvement of this utility model: the outer wall of the mounting shell is provided with a water inlet, and the outer wall of the fixed knife handle is provided with a through hole that communicates with the mounting shell.

[0011] As a further improvement of this utility model, the fixed knife handle has a flow cavity that communicates with the through hole inside.

[0012] As a further improvement of this utility model, two water spray heads that communicate with the flow cavity are installed on the outer wall of the mounting rod.

[0013] As a further improvement of this utility model: the inner wall of the mounting shell is inlaid with a fixed bearing, and the inner wall of the fixed bearing is connected with a limiting ring that is fixedly connected to the fixed tool holder.

[0014] The beneficial effects of this utility model are: the workpiece is chamfered by the first chamfering cutter on the mounting rod, and the chamfering effect on both sides of the workpiece can be controlled by controlling the direction of the movement of the second chamfering cutter, so that the workpiece does not need to be adjusted and the processing efficiency is improved.

[0015] Cooling water enters the mounting housing through the inlet, then enters the flow chamber through the through hole and is sprayed out through the spray nozzle. The coolant sprayed from the spray nozzle is directed at the first and second chamfering cutters, thereby cooling the first and second chamfering cutters and preventing the tool temperature from becoming too high.

[0023] The chamfering mechanism includes a mounting rod 2, which is fixed to the front end of a fixed tool holder 1. A first chamfering cutter 21 is mounted on one end of the mounting rod 2, and a second chamfering cutter 22 is mounted on the outer surface of the mounting rod 2. Fixing screws 23, which abut against the outer wall of the first and second chamfering cutters 21 and 22, are mounted on their outer walls. Limiting blocks 24 are fixed to the inner walls of both the first and second chamfering cutters 21 and 22. A limiting groove 25, formed on the mounting rod 2, is slidably connected to one side of the limiting block 24, thus fixing the fixed tool holder 1 and the output end of the drive device, thereby enabling… The equipment can drive the fixed tool holder 1 to move, so that the first chamfering cutter 21 on the mounting rod 2 can perform chamfering on the workpiece. The second chamfering cutter 22 can control the chamfering of both sides of the workpiece by controlling the direction of its movement, thus eliminating the need to adjust the workpiece and improving processing efficiency. By unscrewing the fixing screws 23 on the first chamfering cutter 21 and the second chamfering cutter 22, the first chamfering cutter 21 and the second chamfering cutter 22 can be disassembled with the cooperation of the limiting block 24 and the limiting groove 25, which facilitates individual replacement and improves practicality.

The water inlet 31 on the mounting shell 3 is connected to an external water supply pipe. During workpiece processing, external cooling water enters the mounting shell 3 through the water inlet 31, then enters the flow chamber 33 through the through hole 32, and is then sprayed out through the spray nozzle 34. The coolant sprayed from the spray nozzle 34 is directed at the first chamfering cutter 21 and the second chamfering cutter 22, thereby cooling the first chamfering cutter 21 and the second chamfering cutter 22 and preventing the tool temperature from becoming too high. Furthermore, through the fixed bearing 4 and with the cooperation of the limit ring 5, when the fixed tool holder 1 rotates, it will not drive the mounting shell 3 to rotate, thus ensuring the normal delivery of coolant.

The second chamfering cutter 22 can control the direction of its movement to control the double-sided chamfering of the workpiece, thus eliminating the need for workpiece adjustment and improving processing efficiency. The water inlet 31 on the mounting shell 3 is connected to an external water pipe. During workpiece processing, external cooling water enters the mounting shell 3 through the water inlet 31 and then flows through the through hole 32 into the...
