DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0030] Embodiment one

[0031] In the prior art, in the machining and production process of zero-class bearings, the assembly of bearing rings is one of the key links. The accurate positioning of the inner and outer rings of the bearing is the core step in the assembly process. The traditional method requires workers to pre-connect the bearing ring to the bearing mounting column to realize the accurate positioning of the bearing ring. However, due to the size difference of different bearings, the corresponding bearing mounting column must be replaced to adapt to bearings of different sizes, which makes the assembly process of different types of bearings complex, and further affects the production efficiency of the bearing.

[0032] To solve the above problems, realize the function of improving the stability and convenience of bearing positioning, refer to Figure 1 And Figure 2 The utility model discloses a bearing assembly positioning clamping jaw. It includes the positioning disc 1 for placing bearing, and its surface is provided with first guide groove 6 and second guide groove 7. First guide groove 6 is arranged on the outer peripheral edge of positioning disc 1 and extends towards the center of positioning disc 1. Second guide groove 7 is located at the center position of positioning disc 1 and extends towards the outer peripheral edge of positioning disc 1.

[0033] First clamping part 2 is slidably connected to first guide groove 6. A clamping piece is arranged on the side of first clamping part 2 facing the center of positioning disc 1. The clamping piece is used for abutting against the outer ring of bearing. First clamping part 2 specifically includes supporting table 4 and sliding part. Supporting table 4 is arranged on the top of positioning disc 1. Sliding part is located at the bottom of supporting table 4 and penetrates into the inside of first guide groove 6. Sliding part can drive supporting table 4 to move along the length direction of first guide groove 6.

[0034] Second clamping part 8 is slidably connected to second guide groove 7 and can abut against the inner ring of bearing. The inside of second guide groove 7 is provided with moving part 11. Second clamping part 8 is connected with moving part 11. Through moving part, the abutting column can move along the length direction of second guide groove 7.

[0035] In the embodiment, first guide groove 6 and second guide groove 7 are distributed in a staggered manner on positioning disc 1. By moving first clamping part 2 and second clamping part 8, the clamping of the inner and outer rings of bearing can be realized. For example, when assembling a certain type of bearing, first, place the bearing on positioning disc 1. Then, push first clamping part 2 so that the clamping piece thereof abuts against the outer ring of bearing. Then, adjust the position of second clamping part 8 through moving part 11 so that the clamping piece thereof abuts against the inner ring of bearing. Thus, the positioning and clamping of the bearing are completed. Compared with the traditional method, the clamping jaw is more convenient to operate without frequent replacement of the mounting column.

[0036] In addition, the staggered distribution of first guide groove 6 and second guide groove 7 is that one second guide groove 7 is arranged between any two adjacent first guide grooves 6. This arrangement makes the clamping positions of first clamping part 2 and second clamping part 8 asymmetric. The asymmetric clamping positions increase the force points at different angles on the bearing, which helps to enhance the stability of the clamping jaw during the clamping process and avoid the bearing from deviating or shaking during the assembly process.

[0037] In the embodiment, first clamping part 2 includes supporting table 4 and sliding part. Supporting table 4 is arranged on the top of positioning disc 1. Sliding part is arranged on the bottom of supporting table 4 and penetrates into the inside of first guide groove 6. Sliding part is suitable for driving supporting table 4 to move along the length direction of first guide groove 6.

[0038] For example, the sliding part can be a sliding block matched with the first guide groove 6, which can slide in the first guide groove 6 to drive the supporting table 4 and the clamping member arranged on the supporting table 4 to move to the required position accurately. In order to position the first clamping part 2, a positioning member 10 is further arranged, which comprises a fixing rod and a fixing hole. The fixing hole is arranged in the first guide groove 6, and the fixing rod penetrates through the sliding part and is inserted into the fixing hole. When the first clamping part 2 moves to the required position, the first clamping part 2 can be fixed at the current position by the cooperation of the fixing rod and the fixing hole, so that the movement of the first clamping part 2 during assembly is avoided, thereby ensuring the accuracy and stability of clamping.

[0039] In the embodiment, the fixing rod can be a screw rod, and the fixing hole can be a threaded hole matched with the screw rod.

[0040] Embodiment two

[0041] Based on the embodiment one, referring to Figure 1 and Figure 2 , the positioning stability of bearings of different sizes is further improved by the cooperation of the first clamping part 2 and the second clamping part 8. The clamping member comprises a low-position clamping member 3 and a high-position clamping member 5. The low-position clamping member 3 is arranged on the side of the supporting table 4 facing the center of the positioning disc 1. The high-position clamping member 5 is arranged on the top of the supporting table 4 and close to the side of the outer peripheral edge of the positioning disc 1. The second clamping part 8 comprises a resisting column arranged on the top of the positioning disc 1. The top and the bottom of the resisting column are both provided with an opening, and the two openings are communicated with each other to form a cavity in the interior of the resisting column. The adjusting part 9 comprises a vertical column. One end of the vertical column is inserted into the interior of the resisting column through the opening, and the other end extends into the second guide groove 7. The outer surface of the vertical column and the inner wall of the cavity are provided with matching threads. The resisting column is moved along the length direction of the vertical column by rotating the resisting column.

[0042] In the specific embodiment, when a smaller bearing needs to be fixed, the user first places the outer ring of the bearing against the low-position clamping member 3 on the positioning disc 1, then moves the resisting column to be in contact with the inner ring of the bearing by the moving part 11, and finally fixes the supporting table 4 and the resisting column to fix the smaller bearing.

[0043] When a larger bearing needs to be fixed, the user first places the outer ring of the bearing against the high-position clamping member 5 on the supporting table 4, then rotates the resisting column to make the resisting column ascend along the vertical column under the action of the screw, until the height of the resisting column is matched with the high-position clamping member 5, and then the moving part 11 drives the resisting column to be in contact with the inner ring of the bearing to fix the larger bearing.

[0044] In the above process, in the initial state, the first clamping part 2 is located at the edge of the positioning disc 1, and the second clamping part 8 is located at the center of the positioning disc 1, and as preferred, the positioning disc 1 is disc-shaped.

[0045] Embodiment three

[0046] On the basis of embodiment one and embodiment two, in order to make the second clamping part 8 move smoothly in the second guide groove 7, referring to Figure 3 , the moving part 11 comprises a moving slider and a lead screw 12, wherein the top of the moving slider is connected with the stand, the lead screw 12 penetrates through the moving slider and is rotationally connected with the inner wall of the second guide groove 7, and the end of the lead screw 12 away from the moving slider is provided with a rotating disc, and the rotating disc is rotated to drive the lead screw 12 to rotate, and then the moving slider moves along the length direction of the lead screw 12.

[0047] In this embodiment, when the second clamping part 8 needs to be moved, the user only needs to rotate the rotating disc to drive the lead screw 12 to rotate, and since the moving slider and the lead screw 12 are threadedly connected, the rotation of the lead screw 12 will be converted into the linear movement of the moving slider along the length direction of the lead screw 12.

[0048] When a plurality of second guide grooves 7 and second clamping parts 8 are provided, each second clamping part 8 needs to be independently moved along the length direction of the corresponding second guide groove 7 by the corresponding moving part 11 to realize the simultaneous clamping of the bearing, and in a specific embodiment, the rotating disc of each moving part 11 can be connected with a motor or other driving device, and then connected to an upper computer for driving to realize the simultaneous rotation of each lead screw 12 and the simultaneous movement of the plurality of second clamping parts 8.

[0049] Embodiment four

[0050] On the basis of embodiment three, in order to improve the stability of the moving slider during movement and reduce the friction between the moving slider and the second guide groove 7 during movement, referring to Figure 4 , the utility model also includes a limiting block 13 and a limiting groove 14, specifically, the bottom of the second guide groove 7 is provided with the limiting groove 14, and the limiting groove 14 extends along the length direction of the lead screw 12, and the bottom of the moving slider is provided with the limiting block 13 matched with the limiting groove 14.

[0051] In this embodiment, through the above structure, the limiting block 13 always slides in the limiting groove 14 during the movement of the moving slider, which can guide and limit the movement of the moving slider, prevent it from deviating or shaking during the movement, and thus improve the stability of the second clamping part 8 during the movement. Meanwhile, the bottom of the limiting block 13 is provided with a roller, which abuts against the inner wall of the limiting groove 14. This arrangement helps to reduce the friction between the moving slider and the second guide groove 7 during the movement, making the movement smoother and further improving the working efficiency of the clamping jaw. In addition, the arrangement of the roller can also play a certain lubricating effect between the limiting block 13 and the limiting groove 14, prolonging the service life of the clamping jaw.

[0052] In summary, in combination with Embodiment One to Embodiment Four, the working steps of the bearing assembly positioning clamping jaw are as follows:

[0053] Firstly, the bearing to be assembled is placed on the positioning disc 1, and then the low-position clamping piece 3 or the high-position clamping piece 5 is selected for clamping according to the size of the bearing. If the bearing is small, the bearing outer ring is placed against the low-position clamping piece 3; if the bearing is large, the bearing outer ring is placed against the high-position clamping piece 5. Then, the first clamping part 2 is pushed or pulled to make the clamping piece abut against the bearing outer ring, completing the clamping of the outer ring. At this time, the sliding part slides in the first guide groove 6, moving the support table 4 and the clamping piece to the desired position, and then the first clamping part 2 is fixed at the current position by the positioning piece 10.

[0054] Then, the position of the second clamping part 8 is adjusted by the moving part 11 to abut against the bearing inner ring. In this process, the rotating disc can be rotated to rotate the lead screw 12, and then the moving slider moves along the length direction of the lead screw 12, finally the abutting column is attached to the bearing inner ring. If multiple second guide grooves 7 and second clamping parts 8 are provided, multiple moving parts 11 can be driven at the same time to realize the simultaneous movement of multiple second clamping parts 8, improving the clamping efficiency.

[0055] During the clamping process, the first guide groove 6 and the second guide groove 7 are distributed in a staggered manner on the positioning disc 1, and there is a second guide groove 7 between any two adjacent first guide grooves 6. This arrangement makes the clamping positions of the first clamping part 2 and the second clamping part 8 asymmetric, increases the force points at different angles on the bearing, and thus enhances the stability of the clamping jaw during the clamping process, avoiding the deviation or shaking of the bearing during the assembly process.

[0056] Finally, when the bearing is stably clamped, subsequent assembly work can be carried out. Since the bearing assembly positioning clamping jaw does not need to be frequently replaced with the mounting column and is easy to operate, it can significantly improve the production efficiency of the bearing. At the same time, due to the stable clamping, the assembly quality of the bearing can also be guaranteed, meeting the production requirements.
