Abstract
Description
Technical Field
[0001] This utility model relates to the field of clutch center sleeve insert processing technology, specifically to an internal clamping mechanism for clutch center sleeve inserts. Background Technology
[0002] The clutch center sleeve insert is a rotating body with a large-diameter end and a small-diameter end, and it has an axial center hole. When machining it, its outer surface needs to be cut first. Generally, this is done manually by inserting it into a cylindrical fixture, forming an internal clamping mechanism. This cylindrical fixture can rotate axially and is connected to the motor shaft drive. As the fixture rotates, a cutting tool can be used to cut the surface of the clutch center sleeve insert. However, because the center hole of the clutch center sleeve insert is circular, conventional cylindrical fixtures are difficult to use effectively, and they are prone to slippage when in contact with the cutting tool, leading to cutting difficulties.

[0005] This utility model provides an inner clamping mechanism for a clutch center sleeve insert, comprising:
[0006] The mounting base has a clamping column at one end, and side grooves are opened on both sides of the clamping column. A rotating rod is rotatably installed in each side groove, and a rocker is installed on the rotating rod. The rocker located on the side of the rotating rod closer to the mounting base is bent and raised outward from the side groove.
[0007] A push plate is slidably installed in each of the side slots along the axial direction of the clamping column. One end of the push plate is located outside the side slot, and the other end is located inside the side slot and abuts against the outer surface of the rocker.
[0008] Furthermore, a limiting groove is formed at the end of the side groove away from the mounting base. A limiting block is slidably installed in the limiting groove along the radial direction of the clamping column. A first spring is connected between the limiting block and the bottom wall of the limiting groove. The first spring can provide an elastic force to push the limiting block out of the side groove. An abutting inclined surface is provided on the side of the outer end of the limiting block away from the mounting base. A push block is provided on the side of the limiting block away from the mounting base.
[0009] Furthermore, a second spring is connected between the bent and raised portion of the rocker and the inner wall of the side groove.
[0010] Furthermore, the end of the rocker away from the mounting base is covered with a rubber layer.
[0011] Further, the end of the push plate close to the hinged plate is provided with a roller, and the roller is in abutment with the outer surface of the hinged plate.
[0012] Further, the mounting seat is provided with a guide sleeve outside each side groove, the push plate is provided with a guide column slidingly inserted into the guide sleeve, and the guide column is connected with the inner end of the guide sleeve through a third spring.
[0013] According to the technical scheme, the inner clamping mechanism for the clutch center sleeve insert is provided.

[0025] As shown in Figs. 1-2 The present embodiment provides an inner clamping mechanism for a clutch center sleeve insert, which comprises a mounting seat 1, a clamp column 2 and a push plate 3.
[0026] The mounting seat 1 is used for transmission connection with the output end of the motor, so that the mounting seat 1 can rotate axially. One end of the mounting seat 1 is provided with the clamp column 2, which is in the shape of a cylinder and has a diameter slightly smaller than the size of the center hole of the clutch center sleeve insert. Side grooves 21 are formed on both sides of the clamp column 2, and a rotating rod 22 is rotatably installed in each side groove 21. A flap 23 is installed on the rotating rod 22. The flap 23 located on the side of the rotating rod 22 close to the mounting seat 1 is bent and raised outward of the side groove 21, and the flap 23 located on the side of the rotating rod 22 away from the mounting seat 1 is placed flat in the side groove 21. When the raised part of the flap 23 is pressed into the side groove 21, the other part of the flap will be levered out of the side groove 21.
[0027] Preferably, the second spring 231 is connected between the raised part of the flap 23 and the inner wall of the side groove 21, and the second spring 231 can provide an elastic force to push the raised part of the flap 23 out of the side groove 21, so that the flap 23 can be automatically reset.
[0028] Further, the end of the rocker plate 23 away from the mounting base 1 is covered with a rubber layer 232, which is beneficial to prevent the rocker plate 23 from damaging the inner wall of the center hole of the clutch center sleeve insert and increase the friction between the rocker plate 23 and the inner wall of the center hole of the clutch center sleeve insert.
[0029] The push plate 3 is slidably installed in each side groove 21 along the axial direction of the clamp column 2. Specifically, the inner walls of the two sides of the side groove 21 are provided with sliding grooves, and the end of the push plate 2 located in the side groove 21 is provided with sliding blocks that are slidably connected with the sliding grooves. One end of the push plate 3 is located outside the side groove 21, and the other end is located inside the side groove 21 and abuts against the outer side surface of the rocker plate 23. When the push plate 3 moves towards the mounting base 1, the part of the rocker plate 23 that is lifted up can be pressed into the side groove 21, so that the end of the rocker plate 23 away from the mounting base 1 is lifted up outward.
[0030] In specific use, the center hole of the clutch center sleeve insert is inserted into the clamp column 2, and the clutch center sleeve insert will push the push plate 3 towards the mounting base 1. When the push plate 3 moves towards the mounting base 1, the part of the rocker plate 23 that is lifted up will be pushed and pressed into the side groove 21, so that the end of the rocker plate 23 away from the mounting base 1 is lifted up outward. Thus, the end of the rocker plate 23 away from the mounting base 1 can abut against the inner wall of the center hole of the clutch center sleeve insert, achieving clamping from the inside. When the clutch center sleeve insert is subjected to rotary cutting machining, the workpiece can be prevented from slipping. In the process of moving the clutch center sleeve insert towards the clamp column 2, the two push plates 3 will be simultaneously pushed, and thus the two ends of the rocker plates 23 away from the mounting base 1 can be simultaneously lifted up outward, so that the center hole of the clutch center sleeve insert and the clamp column 2 always remain coaxial.
[0031] Further, the end of the side groove 21 away from the mounting base 1 is provided with a limiting groove 24, and a limiting block 25 is slidably installed in the limiting groove 24 along the radial direction of the clamp column 2. Specifically, the inner walls of the two sides of the limiting groove 24 are provided with rail strips, and the two sides of the limiting block 25 are provided with rail grooves that are adapted to the rail strips. A first spring 251 is connected between the limiting block 25 and the bottom wall of the limiting groove 24, and the first spring 251 can provide an elastic force to push the limiting block 25 out of the side groove 21. The outer end of the limiting block 25 is provided with an abutting inclined surface 252 away from one side of the mounting base 1. When the center hole of the clutch center sleeve insert is inserted into the clamp column 2, the inner wall of the clutch center sleeve insert will push the abutting inclined surface 252 to push the limiting block 25 into the limiting groove 24. After the clutch center sleeve insert passes through the limiting block 25, the limiting block 25 will be pushed out of the side groove 21 again under the elastic force of the first spring 251, thereby blocking the clutch center sleeve insert and preventing the clutch center sleeve insert from slipping out of the clamp column 2. The side of the limiting block 25 away from the mounting base 1 is provided with a knob 253, which can be used to manually press the limiting block 25 into the limiting groove 24 by pushing the knob 253, so as to cancel the blocking of the clutch center sleeve insert.
[0032] Preferably, the mounting seat 1 is provided with a guide sleeve 11 outside each side groove 21, the guide sleeve 11 is parallel to the axis of the clamp column 2, the push plate 3 is provided with a guide column 32 slidingly inserted into the guide sleeve 11, the guide column 32 is connected with the inner end of the guide sleeve 11 through a third spring 33, the third spring 33 can provide an elastic force to push the guide column 32 out of the guide sleeve 11, so as to automatically reset the push plate 3 after the clutch center sleeve insert is removed from the clamp column 2, when the push plate 3 moves to abut against the guide sleeve 11, the spacing between the push plate 3 and the limiting block 25 will be matched with the length of the clutch center sleeve insert, so that the clutch center sleeve insert can be stably clamped by the push plate 3 and the limiting block 25 when it is sleeved on the clamp column 2, and the displacement of the clutch center sleeve insert is prevented.
[0033] Further, the push plate 3 is provided with a roller 31 at one end close to the warped plate 23, the roller 31 abuts against the outer surface of the warped plate 23, which is beneficial to reduce the friction between the push plate 3 and the warped plate 23, and is helpful to the elastic reset of the push plate 3 and the warped plate 23.
[0034] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit it; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some or all of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should be covered in the scope of the claims and the specification of the present application.
