DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0027] The utility model provides a clamping device for grinding disc springs, comprising a base 1, a first clamping ring and a second clamping ring 8. A telescopic rod 10 is fixed to the top of the base 1, a fixed rod 11 is fixed to the top of the telescopic rod 10, and an electromagnet 3 is fixed to the end of the fixed rod 11. Through the setting of the telescopic rod 10, the telescopic rod 10 can change the height of the fixed rod 11. The telescopic rod 10 can be a hydraulic telescopic rod. The fixed rod 11 is a U-shaped structure, and the vertical end of the fixed rod 11 is in a state of active connection with its horizontal end.

[0028] The first clamping ring includes two clamping plates 12 and two telescopic plates 13. The two clamping plates 12 are connected by the telescopic plates 13. Through the setting of the telescopic plates 13, the distance between the two clamping plates 12 can be changed under the action of external force. In some embodiments of the present application, the telescopic plate 13 includes a bellows fixed to the clamping plate 12, a spring is fixed in the middle of the inner cavity of the bellows, and the end of the spring is fixedly connected to the clamping plate 12. Through the setting of the spring, under the action of the spring rebound force, the two clamping plates 12 can be reset, so as to facilitate the reuse of the first clamping ring.

[0029] A fixing tube 15 adapted to the end of the fixing rod 11 is fixed to the bottom of the clamping plate 12. When the electromagnet 3 is energized, the electromagnet 3 and the fixing tube 15 can be magnetically attracted. Through the setting of the electromagnet 3, when the fixing rod 11 is inserted into the fixing tube 15, the fixing rod 11 and the first clamping ring can be fixed together, so that the telescopic rod 10 drives the first clamping ring to move.

[0030] A cross valve is fixed to the inner wall of one end of the fixing tube 15 away from the clamping plate 12; through the setting of the cross valve, when the fixing tube 15 is separated from the fixing rod 11, the cross valve can seal the fixing tube 15 to prevent debris generated during the grinding of the disc spring from falling into the inner cavity of the fixing tube 15.

[0031] An electromagnet 14 is fixed in the middle of the clamping plate 12 .

[0032] An isolation pad is fixed to the outer wall of the first clamping ring, and the material of the isolation pad can be rubber. The outer wall of the first clamping ring is a conical structure, and the outer wall of the first clamping ring is adapted to the inner wall of the disc spring. The height value of the first clamping ring is less than the height value of the disc spring. The inner diameter of the first clamping ring is greater than the inner diameter of the small-diameter disc spring to be polished. The size of the first clamping ring is designed according to demand and is not limited here. When the disc spring to be polished is placed on the first clamping ring, the outer wall of the first clamping ring contacts the inner wall of the disc spring, and the first clamping ring does not block the diameter of the disc spring, which is convenient for polishing the diameter of the disc spring.

[0033] A telescopic rod 2 is fixed to the top of the base 1, a support plate 3 is fixed to the top of the telescopic rod 2, a dust blowing plate 4 is fixed to the side of the support plate 3 close to the telescopic rod 10, a ventilation pipe 5 is fixed to the bottom end of the dust blowing plate 4, through the arrangement of the dust blowing plate 4 and the ventilation pipe 5, when the clamping device is in use, an external blowing device, such as a blower, can be connected to the air blowing device to blow air into the inner cavity of the dust blowing plate 4 through the ventilation pipe 5, and the air blown out by the dust blowing plate 4 can be blown onto the telescopic rod 10 and the fixed rod 11, so as to prevent the debris generated during the grinding of the disc spring from falling onto the telescopic rod 10 and the fixed rod 11, thereby facilitating the use of the clamping device.

[0034] A rotating rod 7 is movably connected to the middle of the top of the support plate 3, and a servo motor 6 is fixed to the outer side of the top of the support plate 3. The end of the output shaft of the servo motor 6 is fixedly connected to the end of the rotating rod 7 away from the first clamping ring through a reducer. Through the setting of the servo motor 6, the rotation of the servo motor 6 can drive the rotating rod 7 fixedly connected thereto to rotate.

[0035] A second clamping ring 8 is fixed to one end of the rotating rod 7 close to the first clamping ring. The inner wall of the second clamping ring 8 is a conical structure, and the inner wall of the second clamping ring 8 is adapted to the outer wall of the disc spring. When the clamping device is in use, the second clamping ring 8 can be sleeved on the outer wall of the disc spring, and the height value of the first clamping ring is the same as the height value of the second clamping ring 8.

[0036] The second clamping ring 8 is symmetrically provided with electromagnets 9. When the clamping device is in use, when both electromagnets 19 and 14 are energized, electromagnets 19 and 14 are magnetically attracted to each other. Under the action of the suction force, the clamping plate 12 fits tightly against the inner wall of the disc spring. The clamping plate 12 and the second clamping ring 8 are used in combination to fix the position of the disc spring.

[0037] From the above description, it can be seen that the first clamping ring restricts the inner wall of the disc spring, and the second clamping ring 8 restricts the outer wall of the disc spring. The inner and outer walls of the disc spring can be evenly stressed, and the operation of the servo motor 6 can change the position of the disc spring, thereby improving the grinding efficiency of the disc spring.

[0038] The electrical components involved in this application are all prior art, and technicians in this field are familiar with their connection methods. Through these technicians, all the electrical components in this application are connected to their compatible power supplies through wires, and according to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence are described below. The electrical connection is completed in a sequential working order, and the detailed connection means are well known in the art. The following mainly introduces the working principle and process, and no further explanation of the electrical control is given.

[0039] In summary: when the clamping device for grinding the disc spring is used, after the staff puts the disc spring to be ground on the first clamping ring, the telescopic rod 2 shrinks, and the telescopic rod 2 drives the second clamping ring 8 to move down until the second clamping ring 8 is sleeved on the outer wall of the disc spring. The electromagnet 1 9 and the electromagnet 2 14 are both energized, and the electromagnet 1 9 and the electromagnet 2 14 are magnetically attracted to each other. Under the action of the suction force, the clamping plate 12 fits tightly with the inner wall of the disc spring. The clamping plate 12 and the second clamping ring 8 are used in coordination to clamp the disc spring. The telescopic rod 10 shrinks, and the telescopic rod 10 drives the fixed rod 11 to separate from the first clamping ring, and the disc spring can be ground. During the grinding process of the disc spring, if the position of the disc spring needs to be changed, the servo motor 6 rotates, and the servo motor 6 drives the rotating rod 7 fixedly connected thereto to rotate, and the rotating rod 7 drives the second clamping ring 8 to rotate, and the second clamping ring 8 drives the disc spring to rotate, and the position of the disc spring can be quickly changed, which is convenient for grinding the disc spring.
