[0035] The following is combined with Figure 1-3 The utility model is described in further detail.

[0036] Embodiment 1, refer to Figure 1-3 In this embodiment, in order to solve the problem that it is difficult to ensure that the bearing to be processed is at the center of the workbench during the existing bearing processing, which leads to the bearing being easily offset during the extrusion processing, resulting in greater resistance to the bearing rotation and reduced yield rate, the utility model discloses an extrusion device for bearing installation.

[0037] It includes a clamping assembly 100, which includes a support seat 101. The top of the support seat 101 is fixedly connected to a C-shaped plate 102. The top surface of the cross plate of the C-shaped plate 102 is fixedly connected to a hydraulic cylinder 103. The bottom end of the telescopic rod of the hydraulic cylinder 103 passes through the bottom of the cross plate of the C-shaped plate 102 and is fixedly connected to a bearing block 104. The left and right sides of the bearing block 104 are fixedly connected to a first L-shaped rack 105.

[0038] The width of the first L-shaped rack 105 and the width of the second L-shaped rack 1011 are both half the width of the gear 107. The vertical bar of the first L-shaped rack 105 contacts the side of the horizontal bar of the second L-shaped rack 1011, and the side of the horizontal bar of the second L-shaped rack 1011 contacts the side of the clamping bar 109. When the two first L-shaped racks 105 move downward, they can drive the two gears 107 to rotate, and then drive the two second L-shaped racks 1011 to close inward at the same time.

[0039] Rectangular grooves 106 are provided on both sides of the C-shaped plate 102, and the side surfaces of the inner walls of the rectangular grooves 106 are slidingly connected to the side surfaces of the first L-shaped rack 105. The side surfaces of the inner walls of the rectangular grooves 106 are rotatably connected to gears 107, and the gears 107 are meshed with the first L-shaped rack 105. Two grooves 108 are provided on both sides of the top of the support seat 101, and the four grooves 108 are grouped in groups of two and are slidably connected to the inside of clamping bars 109.

[0040] A movable groove 1010 is provided on both sides of the left and right sides of the top surface of the support seat 101, and a second L-shaped rack 1011 is slidably connected inside the movable groove 1010. The vertical bars of the second L-shaped rack 1011 and the vertical bars of the C-shaped clamping bar 109 are both T-shaped, and the cross-sectional shapes of the movable groove 1010 and the groove 108 are both T-shaped. The vertical bars of the T-shaped second L-shaped rack 1011 and the vertical bars of the C-shaped clamping bar 109 are both T-shaped in cross-section, and the movable groove 1010 and the groove 108 can slide vertically without deflection, and the second L-shaped rack 1011 is meshed with the gear 107.

[0041] The specific working principle is: after the bearing enters the upper side of the support seat 101 through the upper tool, the inertia generated by the sliding of the bearing during the movement can ensure that the bearing will not slide to the edge of the top surface of the support seat 101, and then the telescopic rod of the hydraulic cylinder 103 drives the bearing block 104 and the two first L-shaped racks 105 to move downward, and then drives the two gears 107 to rotate, so that the two gears 107 drive the two second L-shaped racks 1011 to close inward at the same time, and the second L-shaped rack 1011 pushes the two clamping bars 109 to move toward the middle when moving, and the two clamping bars 109 can drive the horizontal bars of the C-shaped bars 201 on the side to push the bearing to the middle position of the top of the support seat 101, ensuring that the bearing can be installed correctly and increasing the yield rate of bearing production.

[0042] Example 2, refer to Figure 1-3 In this embodiment, in order to solve the problem that it is difficult to limit the bearing when the bearing is squeezed, which leads to the bearing being easily offset due to pressure, based on the same concept as the above-mentioned embodiment 1, the extrusion device for bearing installation also includes:

[0043] Two grooves 108 are provided on both left and right sides of the top of the support seat 101 , and a clamping bar 109 is slidably connected inside each of the four grooves 108 , two of which form a group.

[0044] The clamping strip 109 is C-shaped, and the bottom of the horizontal strip of the C-shaped clamping strip 109 is slidably connected to the top of the support seat 101, and the side of the vertical strip of the C-shaped clamping strip 109 is fixedly connected with a second compression spring 109a, and one end of the second compression spring 109a is fixedly connected to the inside of the groove 108. The C-shaped clamping strip 109 can conveniently drive the two C-shaped strips 201 to close inward at the same time.

[0045] A movable groove 1010 is formed on both left and right sides of the top surface of the support seat 101 . A second L-shaped rack 1011 is slidably connected inside the movable groove 1010 . The second L-shaped rack 1011 is meshed with the gear 107 .

[0046] The limiting assembly 200 includes a C-shaped bar 201, the side of the horizontal bar of the C-shaped bar 201 is arc-shaped, and the two opposite sides of the horizontal bars of the two C-shaped bars 201 are fixedly connected with rubber blocks 201a. The rubber blocks 201a can stably clamp the bearings with grease adhered to the sides, and the arc-shaped C-shaped bar 201 makes it easy to move the bearings to the center position.

[0047] There are two C-shaped bars 201 , which are movably plugged into the sides of the two clamping bars 109 , respectively. The side of the horizontal bar of the C-shaped bar 201 is fixedly connected with a first compression spring 202 , and one end of the first compression spring 202 is fixedly connected to the side of the clamping bar 109 .

[0048] The specific working principle is: the two second L-shaped racks 1011 drive the two C-shaped bars 201 to close inward at the same time. When the bearing is pushed to the appropriate position, the two C-shaped bars 201 close inward to squeeze and clamp the bearing. At the same time, the vertical rods of the C-shaped bars 201 open to the left and right sides due to the pressure generated by the extrusion, and compress the second compression spring 109a, so that the C-shaped bars 201 can clamp the bearing without compressing and deforming the bearing, thereby ensuring that the bearing will not shift during extrusion installation.

[0049] Example 3, refer to Figure 1-3In this embodiment, in order to solve the problem that the hydraulic cylinder expansion and contraction of some existing bearing extrusion devices during manufacturing may cause the bearing extrusion device to vibrate, based on the same concept as the above-mentioned embodiment 1, the bearing installation extrusion device also includes:

[0050] The clamping assembly 100 includes a support base 101, which is C-shaped, and the bottoms of the two vertical plates of the C-shaped support base 101 are fixedly connected with support plates 101a, and the contact surface between the support base 101 and the ground can be increased through the support plates 101a.

[0051] A circular groove 101c is provided in the middle of the top surface of the support seat 101, and a hard silicone pad is fixedly connected to the bottom of the circular groove 101c. The hard silicone pad can reduce the large pressure exerted by the bearing extrusion device on the bearing, thereby reducing the possibility of bearing damage. The shape of the support plate 101a is an isosceles trapezoid, and four threaded through grooves 101b are provided on the top of the support plate 101a. The contact area between the isosceles trapezoidal support plate 101a and the ground is larger, and the support plate 101a can be fixed with expansion screws through the threaded through grooves 101b.

[0052] The specific working principle is: by setting a trapezoidal support plate 101a, the contact area between the bearing extrusion device and the ground can be increased, so that the force area between the bearing extrusion device and the ground is increased, and at the same time, an expansion screw is used to move to the ground through the threaded groove 101b to fix the bearing extrusion device, thereby reducing the vibration generated by the bearing extrusion device during operation.

[0053] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
