Description

Technical Field

[0001] The utility model relates to the technical field of tool edge grinding, in particular to a tungsten steel carbide tool edge processing and grinding device. Background Art

[0002] Tungsten steel alloy milling cutters usually have a high manufacturing cost, especially in applications that require high precision and special shapes. Therefore, from an economic point of view, grinding and repairing worn milling cutters can significantly extend their service life, thereby reducing the overall tool cost. In contrast, frequently replacing new cutters will increase production costs. Frequent replacement and discarding of worn milling cutters will not only cause a waste of resources, but may also have an adverse impact on the environment. By grinding and repairing worn milling cutters, the demand for new materials can be reduced, thereby reducing the burden on the environment. Currently, tungsten steel alloy milling cutters are manually held and ground on a grinding bed. This operation method has the following potential safety hazards: first, the high temperature generated by the grinding of tungsten steel alloy milling cutters is directly transferred to the hands of personnel, causing burns. Second, the tungsten steel alloy milling cutter is unstable during the grinding process, causing the tool to fly and injure people. Improvements are needed. Therefore, we propose a tungsten steel carbide tool edge treatment and grinding device. Utility Model Content

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] Example 1, as Figure 1-3As shown, the utility model provides a technical solution: a tungsten steel carbide tool edge processing and grinding device, including a grinder 1, a tungsten steel alloy milling cutter 5 and a clamp 4 for assisting in clamping the tungsten steel alloy milling cutter 5, the grinder 1 includes a motor 2, the motor shaft of the motor 2 is provided with a clamp for assembling a grinding disc 3, the clamp of the grinding disc 3 is a clamp provided by the existing grinding machine equipment, and is composed of a stepped shaft and a limiting ring. No further details are given here. The clamp 4 is connected to the telescopic sleeve structure 7 through a gooseneck tube 9, and the bottom end of the telescopic sleeve structure 7 is fixed to the workbench of the grinder 1 by bolts, the clamp 4 includes a square groove column 401, a square groove inner cavity is opened in the middle of the square groove column 401, a V-groove seat A403 is fixedly provided at the bottom of the square groove inner cavity, a V-groove seat B402 is slidingly provided through the top of the square groove inner cavity, and an adjusting screw 405 for adjusting the vertical position of the V-groove seat B402 is threadedly connected to the top of the square groove column 401.

[0018] In a specific embodiment of the present invention, the front end body of the clamp 4 is square and the rear end body is a square groove column 401. The front end body of the clamp 4 is used to connect with one end of the gooseneck tube 9. The connecting end of the gooseneck tube 9 and the front end body of the clamp 4 are connected by a square seat with bolts. The inner cavity of the square groove column 401 is a square groove shape. The V-groove seat B402 and the V-groove seat A403 are arranged relative to each other up and down. The V-groove is convenient for stably clamping the cylindrical end of the tungsten steel alloy milling cutter 5. The adjusting screw 405 is used to adjust the vertical position of the V-groove seat B402. By rotating the adjusting screw 405, the position of the bottom end of the adjusting screw 405 is changed, thereby pushing the vertical position of the V-groove seat B402 to change. When the vertical position of the V-groove seat B402 is adjusted, the guide column 404 slides in the guide hole opened at the top of the square groove column 401, thereby improving the stability of the V-groove seat B402.

[0019] The gooseneck tube 9 is made of stainless steel metal, which not only has a certain degree of support, but also has ductility, so that the processing angle and processing position of the clamp 4 can be flexibly adjusted. The telescopic sleeve structure 7 is a common lifting position adjustment structure. The height can be adjusted by loosening the fastening bolt 701. Tightening the fastening bolt 701 can limit the support height of the telescopic sleeve structure 7. The setting of the telescopic sleeve structure 7 can make up for the problem of limited adjustment range caused by the shorter setting of the gooseneck tube 9. The shorter setting of the gooseneck tube 9 can improve the support.

[0020] In the preferred technical solution, the telescopic sleeve structure 7 includes a sleeve, a sleeve base 6 and a pillar 702 embedded and sliding inside the sleeve. The top end of the sleeve is threadedly connected with a fastening bolt 701. The height can be adjusted by loosening the fastening bolt 701. Tightening the fastening bolt 701 can limit the support height of the telescopic sleeve structure 7.

[0021] In the preferred technical solution, the gooseneck pipe 9 is fixedly provided with a matching seat at both ends, and the matching seats 8 at both ends of the gooseneck pipe 9 are connected to the top end of the support column 702 and the side wall of the clamp 4 through bolts, respectively, and the gooseneck pipe 9 is used to connect the clamp 4 and the telescopic sleeve structure 7.

[0022] In the preferred technical solution, the V-shaped groove seat B402 is fixedly provided with two guide columns 404 at the top, and the two guide columns 404 penetrate the square groove column body 401. When the vertical position of the V-shaped groove seat B402 is adjusted, the guide columns 404 slide in the guide holes opened at the top end of the square groove column body 401, thereby improving the stability of the V-shaped groove seat B402. The V-shaped groove seat B402 is embedded with a bearing at the top, and the bottom end of the adjusting screw 405 is connected to the inner ring of the bearing in interference fit. The adjusting screw 405 is used to adjust the vertical position of the V-shaped groove seat B402. By rotating the adjusting screw 405, the position of the bottom end of the adjusting screw 405 changes, thereby pushing the vertical position of the V-shaped groove seat B402 to change.

[0023] In the preferred technical solution, the outer circumferential surface of the square groove column body 401 is fixedly provided with a heat insulation layer to avoid direct transmission of high temperature generated by the tungsten steel alloy milling cutter 5 to the hands of the personnel, causing burns.

[0024] Working principle: Place the cylindrical end of the tungsten steel alloy milling cutter 5 between the V-shaped groove seat B402 and the V-shaped groove seat A403, rotate the adjusting screw 405, and clamp the cylindrical end of the tungsten steel alloy milling cutter 5 between the V-shaped groove seat B402 and the V-shaped groove seat A403. Turn on the motor 2 to drive the polishing disc 3 to rotate. The operator holds the outer end of the square groove column body 401. Due to the flexible adjustment characteristics of the gooseneck pipe 9, the machining angle and position of the tungsten steel alloy milling cutter 5 can be flexibly adjusted. The outer circumferential surface of the square groove column body 401 is fixedly provided with a heat insulation layer to avoid direct transmission of high temperature generated by the tungsten steel alloy milling cutter 5 to the hands of the personnel, causing burns. At the same time, the clamp is provided to assist in clamping the tungsten steel alloy milling cutter 5, which can avoid the situation that the tungsten steel alloy milling cutter 5 flies and hurts people during polishing, greatly improving the safety during tool polishing.
