Therefore, a positioning and clamping device for bearing processing is proposed to solve the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 - Figure 3This utility model provides an embodiment of a positioning and clamping device for bearing processing, including a processing table 1, which supports the processing equipment. The processing table 1 has strip grooves 2 at both ends of its upper surface. Motors 3 are fixedly installed on both the left and right surfaces of the processing table 1. The output shaft of the motor 3 is fixedly connected to a reciprocating lead screw 4. When the motor 3 is started, it drives the reciprocating lead screw 4 to rotate, so that the reciprocating lead screw 4 drives the adjustment component 5 to perform a clamping action in the horizontal direction, which improves the convenience of clamping and adjusting the bearing during processing. The adjustment component 5 is provided at the threaded part of the outer wall of the reciprocating lead screw 4, and an auxiliary component 6 is provided at the right end of the adjustment component 5.

[0026] Reference Figure 2 - Figure 4 When the clamping angle of the equipment needs to be adjusted, the adjustment component 5 is activated. The adjustment component 5 includes a mounting plate 51, which is threaded to the outer wall of the reciprocating screw 4 via a slot in the inner wall of the moving block 52. The moving block 52 is fixedly connected to the lower surface of the mounting plate 51. The movement of the moving block 52 is driven by the rotation of the reciprocating screw 4, which improves the clamping effect of the equipment on bearings of different thicknesses. The outer wall of the moving block 52 is slidably connected to the groove in the inner wall of the strip groove 2, realizing the positioning and clamping of the bearings processed in the processing table 1, which improves the convenience of positioning and clamping of the equipment. An adjustment frame 53 is fixedly installed on the upper surface of the mounting plate 51. The front surface of the adjustment frame 53 is rotatably connected to the positioning plate 54 via a rotating column 57. By changing the installation height of the positioning bolt 56 and the positioning groove 55, multiple sets of evenly distributed positioning grooves 55 are opened on the right surface of the positioning plate 54. This system enables control of the vertical distance of the clamping block 61. A positioning bolt 56 is detachably connected to the slot on the inner wall of the positioning groove 55, increasing the adaptability and positioning effect of the clamping block 61 for clamping and positioning different types of bearings. A wheel 58 is fixedly connected to the front end of the rotating column 57. The rotating wheel 58 drives the rotating column 57 to rotate, changing the tilt angle of the positioning plate 54. A protrusion 581 is fixedly connected to the outer arc surface of the outer wall of the wheel 58. The deflection groove 531, in conjunction with the protrusion 581, corrects the deflection angle of the rotating column 57. Multiple evenly distributed deflection grooves 531 are opened on the front surface of the adjusting frame 53 near the outer side of the wheel 58, enabling control of the vertical rotation angle of the clamping block 61. The cross-sectional area of ​​the front surface of the protrusion 581 matches the cross-sectional area of ​​the groove in the inner wall of the deflection groove 531, enriching the functionality of the equipment.

[0027] Reference Figure 3 and Figure 5 - Figure 6When the outer wall of the bearing is irregularly shaped, the auxiliary component 6 is activated. The auxiliary component 6 includes an auxiliary block 62, which is fixedly installed on the right surface of the positioning plate 54 by positioning bolts 56. A clamping block 61 is fixedly connected to the lower surface of the auxiliary block 62. By connecting the air inlet 63 through the air inflator, the clamping block 61 is inflated. An air inlet 63 is fixedly installed at the center of the upper surface of the clamping block 61. Multiple sets of evenly distributed airbag strips 64 are fixedly installed in the groove on the right surface of the clamping block 61, causing the airbag strips 64 to expand. The expanded airbag strips 64 wrap around the irregular shape of the outer wall of the bearing, improving the stability of the processed bearing in the positioning and clamping action. Exhaust valves 65 are opened at both the upper and lower ends of the left surface of the clamping block 61 to prevent the processed bearing from falling off under the clamping action, thus enhancing the positioning and clamping effect of the equipment on the bearing.

[0028] Working principle: When the clamping angle of the equipment needs to be adjusted, the adjustment component 5 is activated. The rotating wheel 58 drives the rotating column 57 to rotate, changing the tilt angle of the positioning plate 54. The deflection groove 531, in conjunction with the protrusion 581, corrects the deflection angle of the rotating column 57, thus controlling the vertical rotation angle of the clamping block 61. This improves the clamping effect on bearings of different thicknesses. By changing the installation height of the positioning bolt 56 and the positioning groove 55, the vertical distance of the clamping block 61 is controlled, increasing the adaptability and positioning effect of the clamping block 61 for different types of bearings. The rotation of the lead screw 4 drives the moving block 52 to move, thereby positioning and clamping the bearing in the machining table 1. This improves the convenience of positioning and clamping and enriches the functionality of the equipment. When the outer wall of the bearing is irregularly shaped, the auxiliary component 6 is activated. Through the connection of the air inlet 63 to the air inflator, the clamping block 61 is inflated, causing the air bladder strip 64 to expand. The expanded air bladder strip 64 wraps around the irregular shape of the outer wall of the bearing, improving the stability of the machined bearing in the positioning and clamping action, preventing the machined bearing from falling off under the clamping action, and enhancing the positioning and clamping effect of the equipment on the bearing.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
