Description

Technical Field

[0001] The present application relates to the field of bearing processing, and in particular, to a multi-station fixture for bearing processing. Background Art

[0002] Bearings are used to determine the relative motion position of rotating shafts and other parts, and they play a supporting or guiding role. Their main function is to support mechanical rotating bodies to reduce the mechanical load friction coefficient of the equipment during the transmission process. According to the different friction properties of the moving elements, bearings can be divided into rolling bearings and sliding bearings. Bearings need to be clamped during the processing to prevent them from falling off or other production hazards during the processing.

[0003] During the subsequent processing of existing bearings, since the fixture can only complete the positioning and fixing of one bearing at a time, the bearings clamped on the fixture need to be frequently replaced during the subsequent processing. The overall operation is relatively cumbersome and requires workers to stay in front of the corresponding air collection for a long time to operate. Therefore, a multi-station fixture for bearing processing is needed to assist in solving this problem. Utility Model Content

The sliding blocks 51 are threadedly matched with the adjusting rod 10. A mounting plate 5 is installed at the top of the sliding block 51. The clamping blocks 4 and the mounting plates 5 are staggered. A clamping area is formed between a clamping block 4 and the mounting plate 5. The mounting plate 5 is symmetrically protruded toward one side of the clamping block 4 corresponding to the clamping area, and a protruding block 7 is provided on the protruding block 7. A clamping seat 6 is installed in the sleeve, and an auxiliary protruding block 7 is installed inside the clamping seat 6 to push the ejection spring 8 for reset. Through the set ejection spring 8, the device bearing can be elastically clamped and positioned during operation, while ensuring clamping, and avoiding excessive clamping force to cause bearing damage. A clamping groove 9 is provided on the side adjacent to the clamping block 4 and the corresponding clamping seat 6, and a clamping motor 11 for driving the adjusting rod 10 to rotate is installed at one end of the base plate 1, and a worm 111 is installed at the front end of the machine shaft of the clamping motor 11, and a worm wheel 101 is fixed to the end of the adjusting rod 10 close to the clamping motor 11, and the worm wheel 101 and the worm 111 cooperate with each other for transmission.

[0033] By means of the clamping assembly 3 arranged at the top of the base plate 1, the staggered clamping blocks 4 and the mounting plate 5 and the adjusting rod 10 thereon cooperate with each other, multiple bearings can be placed in different clamping grooves 9 during operation, the clamping motor 11 is started, the clamping motor 11 drives the worm 111 to rotate, the worm 111 cooperates with the worm wheel 101 for transmission, so that the worm wheel 101 rotates, and then the adjusting rod 10 rotates, the sliding block 51 is threadedly cooperated with the adjusting rod 10, so that the position of the sliding block 51 is changed, and the mounting plate 5 is driven to move as a whole while the position of the sliding block 51 changes, and the mounting plate 5 is driven to move as a whole during the movement of the mounting plate 5, and the clamping seat 6 is driven to move as a whole, and several bearings are synchronously clamped and installed in the corresponding clamping grooves 9, so as to complete the positioning and fastening processing of multiple bearings, and in the subsequent work process, the overall clamping and positioning of the bearings at multiple workstations can be used to reduce the overall frequency of bearing replacement in the subsequent work, and the workers can perform other operations during the processing.

[0034] Reference Figure 1 , Figure 4 and Figure 5As shown, the clamping block 4 is symmetrically and vertically drilled with a through hole 41, the top of the substrate 1 is provided with a positioning hole 12 which is connected with the through hole 41, and a positioning component 13 is installed through the through hole 41 and the positioning hole 12. The positioning component 13 includes a positioning sleeve 14 which is vertically installed in the through hole 41, an extrusion cavity is provided inside the positioning sleeve 14, and a plug post 15 is installed in the extrusion cavity. An embedding disk 18 is rotatably embedded and installed at the top of the positioning sleeve 14, and a rotating rod 16 is protrudingly provided at the bottom of the embedding disk 18. The rotating rod 16 is installed on the plug post 15, and the plug post 15 and the rotating rod 16 are threadedly engaged. A trumpet-shaped extrusion hole is provided at the outer side of the positioning sleeve 14 near the bottom, and a ball 17 is installed at the extrusion hole. The plug post 15 and the ball 17 are extruded in cooperation with each other, and a positioning ring groove 121 which cooperates with the ball 17 for positioning is provided at the inner edge of the positioning hole 12.

[0035] The base plate 1 and the clamping block 4 are positioned by means of the positioning assembly 13, and the embedded disk 18 is reversed. The embedded disk 18 drives the rotating rod 16 to rotate as a whole, and the plug post 15 is threadedly engaged with the rotating rod 16, so that the plug post 15 rises as a whole, and in the process of the plug post 15 rising, the ball 17 is driven to shrink inward as a whole and withdraw from the positioning ring groove 121. When the ball 17 is retracted as a whole, the positioning sleeve 14 is ejected by the action of the compressed ejection spring 19, thereby completing the disassembly and subsequent replacement of the clamping block 4, and can improve the overall replacement efficiency of the entire clamping block 4 when the clamping block 4 needs to be replaced later.

[0036] An ejection spring 19 is installed at the bottom of the positioning sleeve 14.

The plug post 15 is a block with a rectangular vertical cross-section, and the end of the plug post 15 facing the ball 17 is tapered.

[0037] A limiting strip 141 is symmetrically protruding on the outer side of the positioning sleeve 14, and a limiting groove 42 is vertically symmetrically provided on the inner side of the through hole 41. The limiting strip 141 and the limiting groove 42 are plugged in cooperation with each other. Through the cooperation between the setting limiting strip 141 and the limiting groove 42, it can be ensured that the embedded disk 18 will not drive the positioning sleeve 14 to rotate during the adjustment and rotation process during the working process.

[0038] Working principle:

[0039] During operation, the protruding plate 2 is fixed at the corresponding position by bolts, the bearing is placed in the clamping groove 9 between the clamping block 4 and the clamping seat 6, and the clamping motor 11 is started. The clamping motor 11 drives the worm 111 to rotate, and the worm 111 cooperates with the worm wheel 101 to rotate the worm wheel 101, thereby rotating the adjusting rod 10, and the sliding block 51 is threadedly matched with the adjusting rod 10, so that the position of the sliding block 51 changes, and the mounting plate 5 is driven to move as a whole when the position of the sliding block 51 changes. During the movement of the mounting plate 5, the clamping seat 6 is driven to move as a whole, and several bearings are synchronously clamped. It is installed at the corresponding clamping groove 9 to complete the positioning and tightening of multiple bearings, which is convenient for the overall processing of the bearings at multiple stations. When the clamping block 4 needs to be disassembled and replaced, the embedded disk 18 is reversed, and the embedded disk 18 drives the rotating rod 16 to rotate as a whole. The threaded engagement between the plug post 15 and the rotating rod 16 causes the plug post 15 to rise as a whole, and in the process of the plug post 15 rising, the ball 17 is driven to shrink inward as a whole and withdraw from the positioning ring groove 121. When the ball 17 is retracted as a whole, the positioning sleeve 14 is ejected under the action of the compressed ejection spring 19, thereby completing the disassembly and subsequent replacement of the clamping block 4.
