Description

Technical Field

[0001] The utility model belongs to the technical field of grinding wheel clamps, in particular to a combined brazing super-hard abrasive grinding wheel clamp. Background Art

[0002] Super-hard abrasive grinding wheels have high wear resistance. During the grinding process, the size, shape and morphology of the abrasive grains change little, which is more suitable for high-precision processing and has high production efficiency. Therefore, it is very necessary to design a fixture that can effectively clamp the super-hard abrasive grinding wheel.

[0003] At the same time, the application number is 202123048152.3, which is a grinding wheel clamp for grinding wheel production, including a base, a motor is fixedly connected to the middle part of the bottom wall of the base, a double-headed screw is passed through and fixedly connected to the middle part of the second bevel gear, a wall away from the inside of the connecting block is fixedly connected to a spring, and the end close to the slider is fixedly connected to a clamp, and the end close to the clamp is fixedly connected to a protective pad. In the utility model, the motor is turned on to drive the first bevel gear to rotate, and finally the connecting block is moved so that the grinding wheel can be clamped and fixed. It is simple and convenient. After being subjected to resistance, the clamp moves toward the inside of the connecting block, thereby driving the slider to squeeze the spring to deform. After the spring is deformed to a certain extent, the grinding wheel is clamped, which ensures that the force applied to the grinding wheel during the clamping process is slow and gentle. The protective pad further avoids damage and improves product quality.

[0004] An existing grinding wheel clamp used for grinding wheel production cannot effectively clamp grinding wheels with different inner diameters during use, and different types of clamps need to be replaced for clamping, which reduces the practicality of the clamp and increases the difficulty of clamping and fixing the grinding wheel.

[0005] Therefore, a combined brazing super-hard abrasive grinding wheel fixture is proposed to solve the above problems. Utility Model Content

[0006] In order to solve the problems raised in the above background technology, the utility model provides a combined brazing super-hard abrasive grinding wheel fixture, which has the advantage of being able to effectively clamp grinding wheels with different inner diameters.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a combined brazed super-hard abrasive grinding wheel fixture, comprising a base, a first support frame is fixedly connected to the top of the base, a servo motor is fixedly connected to the top of the first support frame, a rotating shaft is fixedly connected to the end of the output shaft of the servo motor, a jacket is provided on the outer side of the rotating shaft, three groups of square grooves are provided inside the jacket, a connecting block is fixedly connected to the inside of the square groove, one end of the connecting block is fixedly connected to a spring, one end of the spring is fixedly connected to a top block, and a grinding wheel is fitted on the outer side of the top block.

[0008] Preferably, an annular groove is provided inside the jacket, a rotating rod is rotatably connected inside the annular groove, a sliding block is rotatably connected to one side of the rotating rod, a top column is embedded inside the sliding block, and the top column passes through the jacket and is fixedly connected to the inner side of the top block.

[0009] Preferably, a first clamping plate and a second clamping plate are fitted on both sides of the grinding wheel, a through hole is provided inside the first clamping plate, and a bolt is inserted and connected inside the through hole.

[0010] Preferably, a groove is provided inside the first clamping plate, a gasket is embedded inside the groove, and the gasket is made of rubber.

[0011] Preferably, a mounting frame is fixedly connected to the bottom end of the servo motor, and one side of the mounting frame is fixedly connected to one side of the first supporting frame.

[0012] Preferably, a connecting rod is fixedly connected to the inside of the base, a second support frame is sleeved on the outside of the connecting rod, and one end of the rotating shaft is embedded in the inside of the second support frame.

[0013] Preferably, a collecting frame is fitted on the upper portion of the base, and a pull ring is fixedly connected to the top of the collecting frame.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model sets a rotating shaft. When clamping and fixing grinding wheels with different inner diameters, the grinding wheel is firstly sleeved on the outer side of the rotating shaft so that the inner wall of the grinding wheel fits with one side of the top block. Because the outer side of the rotating shaft is sleeved with a clamping sleeve, three groups of square grooves are opened inside the clamping sleeve, and the inside of the square groove is fixedly connected with a connecting block, one end of the connecting block is fixedly connected with a spring, and one end of the spring is fixedly connected with the top block. Therefore, under the action of the spring, the top block is tightly fitted with the inner wall of the grinding wheel, thereby realizing effective clamping of grinding wheels with different inner diameters. There is no need to replace different types of clamps for clamping, thereby increasing the practicality of the clamp and improving work efficiency.

[0016] 2. The utility model sets a rotating shaft. When the rotating shaft rotates, since an annular groove is opened inside the jacket and a rotating rod is rotatably connected inside the annular groove, under the action of centrifugal force, the rotating rod will push against a sliding block rotatably connected on one side and slide inside the square groove. The sliding block drives the top column embedded inside to move. Since the top column passes through the jacket and is fixedly connected to the inner side of the top block, the sliding block presses against the top column to apply pressure to the top block, so that the top block fits tightly against the inner wall of the grinding wheel, thereby preventing the grinding wheel from moving during rotation and increasing the clamping and fixing capacity.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Specifically, an annular groove 25 is provided inside the jacket 5, and a rotating rod 11 is rotatably connected inside the annular groove 25. A slider 12 is rotatably connected to one side of the rotating rod 11. A top column 13 is embedded inside the slider 12, and the top column 13 passes through the jacket 5 and is fixedly connected to the inner side of the top block 9.

[0025] Furthermore, a first clamping plate 14 and a second clamping plate 15 are fitted on both sides of the grinding wheel 10 , a through hole 16 is opened inside the first clamping plate 14 , and a bolt 17 is inserted and connected inside the through hole 16 , so that the first clamping plate 14 and the second clamping plate 15 can effectively clamp and fix the grinding wheel 10 .

[0026] Furthermore, a groove 18 is formed inside the first clamping plate 14, and a gasket 19 is embedded inside the groove 18. The gasket 19 is made of rubber and can effectively prevent the first clamping plate 14 and the second clamping plate 15 from damaging the grinding wheel 10 during the process of tightening the nut, thereby reducing economic losses.

[0027] It is worth noting that the bottom end of the servo motor 3 is fixedly connected to a mounting frame 20, and one side of the mounting frame 20 is fixedly connected to one side of the first support frame 2, which can effectively fix the servo motor 3 to prevent shaking during rotation.

[0028] It is worth noting that a connecting rod 22 is fixedly connected to the inside of the base 1, a second support frame 21 is sleeved on the outer side of the connecting rod 22, and one end of the rotating shaft 4 is embedded in the inside of the second support frame 21, which can support the rotating shaft 4 and prevent shaking during rotation, thereby reducing work efficiency.

[0029] It is worth mentioning that a collection frame 23 is fitted on the upper part of the base 1, and a pull ring 24 is fixedly connected to the top of the collection frame 23. The staff can effectively collect the waste chips generated by the grinding wheel 10 to prevent the waste chips from being everywhere and causing inconvenience in cleaning. After finishing the work, the staff pulls the pull ring 24 to take out the collection frame 23, thereby improving the work efficiency of the staff.

[0030] Among them, the servo motor 3 is the existing technology and will not be described in detail; at the same time, the utility model also includes a power supply, a controller and a switch, which are not the main technical points of this patent and will not be described in detail.

[0031] Working principle and process:

[0032] When the staff needs to clamp and fix the grinding wheel 10 with different inner diameters, firstly, the grinding wheel 10 is sleeved on the outer side of the rotating shaft 4, so that one side of the grinding wheel 10 is in contact with the first clamping plate 14, and then the second clamping plate 15 is installed, so that one side of the second clamping plate 15 is in contact with the other side of the grinding wheel 10, and the bolt 17 is passed through the through hole 16, and the nut is tightened to clamp, so as to prevent the grinding wheel 10 from moving left and right during the rotation process, improve the clamping and fixing efficiency, and make the grinding wheel 10 more stable. Under the action of the gasket 19 embedded in the groove 18, it can effectively prevent the grinding wheel 10 from moving left and right during the tightening process. In the embodiment, the first clamping plate 14 and the second clamping plate 15 damage the grinding wheel 10, increasing the problem of economic losses, so that the inner wall of the grinding wheel 10 fits with one side of the top block 9. Because the outer side of the rotating shaft 4 is provided with a jacket 5, the inside of the jacket 5 is provided with three sets of square grooves 6, the inside of the square groove 6 is fixedly connected with a connecting block 7, one end of the connecting block 7 is fixedly connected with a spring 8, and one end of the spring 8 is fixedly connected with the top block 9. Therefore, under the action of the spring 8, the top block 9 fits tightly with the inner wall of the grinding wheel 10, and the servo motor 3 fixedly connected to the top of the first support frame 2 is started. Under the action of the bracket 20, the servo motor 3 can be effectively fixed to prevent shaking during the rotation process. The servo motor 3 drives the rotating shaft 4 fixedly connected to the end of its output shaft to rotate. Because the inner ring groove 25 is provided with a ring groove 25, the inner rotation of the ring groove 25 is connected with a rotating rod 11. Under the action of centrifugal force, the rotating rod 11 will push the slider 12 connected to one side to slide inside the square groove 6. The slider 12 drives the internal embedded top column 13 to move. Because the top column 13 penetrates the jacket 5 and is fixedly connected to the inner side of the top block 9, the slider 12 presses the top block 9 tightly. The column 13 applies pressure to the top block 9, so that the top block 9 fits tightly against the inner wall of the grinding wheel 10, preventing the grinding wheel 10 from moving during rotation, increasing the clamping and fixing ability, and realizing effective clamping of grinding wheels 10 with different inner diameters. It can be clamped without replacing different types of clamps, which increases the practicality of the clamp and improves the work efficiency of the staff. With the help of a collection frame 23 fitted on the upper part of the base 1, the staff can effectively collect the waste chips generated by the operation of the grinding wheel 10, and then use the pull ring 24 to take out the collection frame 23, which improves the work efficiency of the staff.
