Description

Technical Field

[0001] The utility model relates to the technical field of processing equipment, in particular to a common sharpening machine for drills and milling cutters. Background Art

[0002] The tool grinder that can be used for drill bits and milling cutters is also called a drilling and milling tool grinder or a drilling and milling compound machine. It is a device that can grind drill bits and milling cutters. Before grinding, the tool needs to be inserted into the fixture, and then the fixture is inserted into the tool seat for tool adjustment. After the adjustment is completed, it is taken out. The grinding disc is driven to rotate by a motor. There is a limited cylinder seat on the side of the grinding disc. A basic disc with a positioning groove is installed on the side of the cylinder seat away from the grinding disc, and the fixture contains corresponding protrusions. After the fixture clamps the tool, it passes through the cylinder seat and contacts the grinding disc for grinding. During the insertion, the protrusion will be inserted into the positioning groove and has a certain range of motion. The purpose is to allow slight rotation during grinding. After grinding one side, the fixture is taken out and turned so that the grinding disc can grind the other side of the tool.

[0003] In the process of implementing this solution, the inventors found that the following problems existed in the prior art and have not been well solved: since the inner surface of the traditional cylinder seat is smooth, when the staff holds the clamp and drives the tool to pass through the cylinder seat, it is unobstructed. This results in the speed at which the clamp drives the tool to insert being uncontrollable and can only be slowed down manually. When the insertion speed is too fast or slightly faster, the high-speed rotating grinding wheel can easily cause excessive grinding of the tool, which in turn causes defects in the tool after grinding, which has a certain impact on the use of the tool. Utility Model Content

[0004] The main purpose of the utility model is to provide a common sharpening machine for drill bits and milling cutters, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A common sharpening machine for drill bits and milling cutters comprises a mounting seat, a limiting cylinder seat is fixed on the top of the mounting seat, a plurality of sliding grooves are bored at the rear end of the inner wall of the limiting cylinder seat, the inner rear ends of the sliding grooves are slidably connected with tension springs, a sliding block is fixed at the end of the sliding grooves away from the tension springs, a rear hanging ring is embedded at the rear end of the limiting cylinder seat, a front hanging ring is provided at the front end of the rear hanging ring, an annular sliding groove is bored on the side of the rear hanging ring close to the front hanging ring, an annular sliding block is provided on the side of the front hanging ring close to the rear hanging ring, and an anti-slip rubber ring is bonded to the side of the front hanging ring away from the annular sliding block.

[0007] Preferably, the annular sliding block is inserted into the annular sliding groove and is slidably connected thereto.

[0008] Preferably, the outer wall of the rear hanging ring is fixedly connected to one side close to the tension spring.

[0009] Preferably, the sliding blocks are respectively fixedly connected to one end of the tension spring that is close to the other end.

[0010] Preferably, a plurality of mounting holes are drilled on the front side surface of the limiting cylinder seat.

[0011] Preferably, the inner diameters of the rear hanging ring and the front hanging ring match, and the inner diameter of the anti-slip rubber ring is smaller than the inner diameter of the front hanging ring.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. When the clamp passes through the limit cylinder seat, its inserted end will first touch the anti-slip rubber ring, thereby driving the anti-slip rubber ring, the front hanging ring and the rear hanging ring to be inserted forward together. When the rear hanging ring moves backward, it will drive the tension spring to slide in the slide groove. At this time, the slider can provide moving resistance to the tension spring, so that the backward movement speed of the rear hanging ring is reduced, and then the backward movement speed of the tool is reduced. Finally, the tool can slowly contact the grinding disc for grinding, which has a better protective effect on the tool.

[0014] 2. The clamp moves after touching the anti-slip rubber ring. When the staff slightly rotates the clamp, the rotation of the clamp will drive the front hanging ring to rotate through the anti-slip rubber ring. The front hanging ring can achieve the rotatable effect through the rotation of the annular slider in the annular slide groove. During rotation, the anti-slip rubber ring can provide a protective effect during contact to avoid wear on the clamp surface caused by rotation, thus providing a certain protective effect on the clamp.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, the drill bit and milling cutter common sharpening machine comprises a mounting seat 1, a limiting cylinder seat 2 is fixed on the top of the mounting seat 1, a plurality of slide grooves 4 are bored at the rear end of the inner wall of the limiting cylinder seat 2, the inner rear end of the slide groove 4 is slidably connected with a tension spring 6, a slider 5 is fixed at the end of the slide groove 4 away from the tension spring 6, a rear hanging ring 7 is embedded at the rear end of the inner part of the limiting cylinder seat 2, a front hanging ring 8 is provided at the front end of the rear hanging ring 7, an annular slide groove 9 is bored on the side of the rear hanging ring 7 close to the front hanging ring 8, an annular slider 10 is provided on the side of the front hanging ring 8 close to the rear hanging ring 7, and an anti-slip rubber ring 11 is bonded to the side of the front hanging ring 8 away from the annular slider 10.

[0022] Specifically, the annular sliding block 10 is inserted into the annular sliding groove 9 and is slidably connected thereto, so that the clamp can perform the rotation required for grinding after contacting the anti-slip rubber ring 11 .

[0023] Specifically, the outer wall of the rear hanging ring 7 is fixedly connected to one side close to the tension spring 6, and the slider 5 is fixedly connected to one end close to the tension spring 6, so that the slider 5 can provide a pulling force to the tension spring 6, so that the movement of the rear hanging ring 7 has a certain resistance.

[0024] Specifically, a plurality of mounting holes 3 are drilled on the front surface of the limiting cylinder seat 2 to facilitate connection with the basic plate with positioning grooves.

[0025] Specifically, the inner diameters of the rear hanging ring 7 and the front hanging ring 8 match, the inner diameter of the anti-slip rubber ring 11 is smaller than the inner diameter of the front hanging ring 8, and the wider anti-slip rubber ring 11 can provide better protection for the clamp.

[0026] When the rear hanging ring 7 moves backward, it will drive the tension spring 6 to slide in the slide groove 4. At this time, the slider 5 can provide moving resistance to the tension spring 6, so that the backward movement speed of the rear hanging ring 7 is reduced, and then the backward movement speed of the tool is reduced. Finally, the tool can slowly contact the grinding disc to perform grinding work, which has a good protection effect on the tool. The clamp moves after touching the anti-slip rubber ring 11. When the staff slightly rotates the clamp, the rotation of the clamp will drive the front hanging ring 8 to rotate through the anti-slip rubber ring 11, and the front hanging ring 8 can achieve a rotatable effect through the rotation of the annular slider 10 in the annular slide groove 9. When rotating, the anti-slip rubber ring 11 can provide a protective effect during contact to avoid the wear of the clamp surface caused by rotation, which has a certain protection effect on the clamp.
