Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing, in particular to a press machine used for bearing processing. Background Art

[0002] Bearings are used to support rotating shafts and reduce friction between the rotating shaft and other structures when the rotating shaft rotates. Bearings are generally composed of an inner ring and an outer ring with balls between them. The inner and outer rings are respectively fixed to the rotating shaft and other structures to support the rotating shaft. During the installation and removal of bearings, the bearings are often pressed into the installation groove of the workpiece by a press.

[0003] When installing the bearing, it is necessary to use a clamp to stably clamp the bearing so that the axis of the bearing coincides with the axis of the rotating shaft. In order to prevent the bearing from moving during the pressure process, the clamp needs to apply a large clamping force to the bearing. During the process of the press applying pressure to the bearing, the bearing will move relative to the clamp, and the clamp is likely to scratch the outer ring of the bearing, so further improvements can be made.

[0024] See also Figure 1-2The push assembly 6 includes a guide rod 61 arranged in an array on the surface of the pressure plate 4. The surface of the guide rod 61 is provided with a sliding hole 62 corresponding to the array. The guide rod 61 is inserted into the sliding hole 62. A limit plate 63 is fixedly installed on the top of the sliding hole 62. The limit plate 63 prevents the guide rod 61 from being separated from the sliding hole 62. A pressing ring 64 is fixedly installed at the bottom of the limit plate 63. The guide rod 61 is arranged on the top of the pressing ring 64 in an array corresponding to the array. A spring 65 is sleeved on the outer side of the guide rod 61. The spring 65 is fixedly installed between the pressure plate 4 and the pressing ring 64. The elasticity of the spring 65 makes the pressing ring 64 have a tendency to move downward away from the pressure plate 4.

[0025] See also Figure 3 The telescopic assembly 7 includes a sleeve 71 arranged in an array on the top of the base 1, a plug rod 72 is inserted into the top of the sleeve 71, and a second spring 73 is fixedly installed between the bottom end of the plug rod 72 and the bottom wall of the sleeve 71. Thus, the assembly of the sleeve 71, the plug rod 72 and the second spring 73 can be retracted and support the clamping assembly 8 and the adjustment assembly 9. When the clamping assembly 8 and the adjustment assembly 9 are pressed and moved downward, the assembly of the sleeve 71, the plug rod 72 and the second spring 73 is retracted.

[0026] See also Figure 3-4 The clamping assembly 8 includes a support ring 81 fixedly mounted on the top of the insertion rod 72. A linear slide groove 82 is provided in an array on the surface of the support ring 81. A slider 83 is slidably connected in the linear slide groove 82. A clamping arm 84 is fixedly mounted on the top of the slider 83. The clamping arm 84 is arranged along the radius of the support ring 81. An L-shaped clamping plate 85 is fixedly mounted on one end of the clamping arm 84 close to the axis of the support ring 81. A sliding column 86 is fixedly mounted on the top of the other end of the clamping arm 84. A support plate 87 is arranged in an array on the inner wall of the support ring 81. Each support plate 87 is located between two adjacent clamping arms 84. The horizontal part of the L-shaped clamping plate 85 is flush with the top of the support plate 87. Thus, the bearing is pre-loaded by the support plate 87, and then the slider 83 slides in the linear slide groove 82, and the assembly of the clamping arm 84 and the L-shaped clamping plate 85 clamps the bearing. A sleeve 88 is fixedly mounted on the circumferential surface of the support ring 81.

[0027] See also Figure 3-4The adjustment assembly 9 includes a rotating ring 91 inserted in the sleeve 88, and the inner and outer diameters of the support ring 81 and the rotating ring 91 are equal. The diameter of the insert plate 5 is smaller than the inner diameter of the rotating ring 91, and the diameter of the pressure plate 4 is smaller than the outer diameter of the rotating ring 91. The surface of the rotating ring 91 is provided with an array of arc grooves 92, and the arc grooves 92 correspond to the slide posts 86 one by one. The slide posts 86 are slidably connected in the arc grooves 92, so that when the rotating ring 91 is driven to rotate, the inner wall of the rotating ring 91 located at the arc groove 92 squeezes the slide posts 86, and drives the slider 83 to slide in the linear slide groove 82. A fixing ring 93 is fixedly installed on the top of the rotating ring 91, and a rotating arm 94 is arranged in an array on the circumferential surface of the fixing ring 93. The rotating arm 94 is fitted on the surface of the sleeve 88. A threaded hole is opened on the surface of the rotating arm 94. The rotating arm 94 is threadedly connected with a bolt 95 through the threaded hole. The bolt 95 abuts on the surface of the sleeve 88. The cross section of the sleeve 88 is an inverted L shape, and the rotating arm 94 is U-shaped. The rotating arm 94 is sleeved on the outer side of the annular flange part at the top of the sleeve 88. The setting of the bolt 95 facilitates the rotating ring 91 to be fixed on the surface of the sleeve 88 after rotation. A hand handle 96 is fixedly installed on the surface of the rotating arm 94. The setting of the hand handle 96 facilitates the rotating ring 91 to be pushed to rotate.

[0028] Working principle: First, place the bearing on the top of the support plate 87, then hold the handle 96 to push the rotating ring 91 to rotate, and the inner wall of the rotating ring 91 at the arc groove 92 squeezes the sliding column 86, thereby driving the slider 83 to slide in the linear slide groove 82, so that the clamping arm 84 moves toward the axis of the supporting ring 81, and the L-shaped clamping plate 85 clamps from the outer ring of the bearing, so that the axis of the bearing coincides with the axis of the supporting ring 81, and then tighten the bolt 95, and the rotating arm 94 is fixed on the sleeve 88; then, place the rotating shaft on the top of the base 1 and directly below the bearing;

[0029] Then, the output shaft of the hydraulic cylinder 3 is extended, so that the pressure plate 4, the embedded plate 5 and the pushing assembly 6 are synchronously moved downward, the pressure ring 64 abuts against the top of the rotating ring 91, the pressure ring 64 is close to the pressure plate 4, the spring 1 65 is squeezed and contracted, the embedded plate 5 is inserted into the inside of the rotating ring 91, and abuts against the top of the bearing, so that the output shaft of the hydraulic cylinder 3 continues to extend, the embedded plate 5 pushes the bearing to move downward, and the pressure ring 64 pushes the rotating ring 91 to move downward synchronously, so that the bearing is installed on the rotating shaft;

[0030] During this process, the rod 72 slides into the sleeve 71, and the spring 2 73 is squeezed and contracted, so that the assembly of the sleeve 71, the rod 72 and the spring 2 73 contracts, causing the bearing and the clamping assembly 8 and the adjustment assembly 9 to move downward synchronously, preventing the bearing and the L-shaped clamping plate 85 from moving relative to each other and scratching the outer ring of the bearing.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
