Description

Technical Field

[0001] The utility model relates to the technical field of bearing seats, in particular to a positioning tooling for bearing seats. Background Technique

[0002] Where there is a bearing, there must be a support point. The inner support point of the bearing is the shaft, and the outer support is the so-called bearing seat. The bearing seat is a component in mechanical equipment used to support the bearing, and it plays an important role in ensuring the stable operation of the bearing and extending the service life of the equipment.

[0003] Patent No. CN 212600493 U discloses a positioning tooling for bearing seat processing, which stably and reliably positions the bearing seat to be processed, and uses the plane where the lower stop is located as the positioning reference to process the inner hole and end face, eliminating the need to calibrate the bearing seat each time, greatly improving the processing efficiency, reducing the labor intensity of workers, and improving the accuracy and quality of the processed finished products.

[0004] However, in use, it has the following defects:

[0005] Although a positioning component with a stop is set to perform reference positioning on the bearing seat, during the positioning process, the bearing seat is pressed and positioned, which results in manually releasing the pressing component and then removing and replacing it each time after processing the bearing seat, being rather troublesome and affecting the processing efficiency. Content of the Utility Model

[0006] The purpose of the utility model is to provide a positioning tooling for bearing seats, which solves the problem that it is rather troublesome and affects the processing efficiency that the pressing component needs to be manually released and then removed and replaced each time after processing the bearing seat as mentioned in the background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A positioning tooling for bearing seats, including a base, a cross bar, a positioning plate and ventilation holes. Adjustment grooves are respectively opened on the left and right sides at the center of the top end of the base. Sliders are slidably connected inside the adjustment grooves, and clamping blocks are fixedly connected to the top ends of the sliders. Fixed frames are fixedly connected to the four corners of the top end of the base. A lead screw is vertically rotatably connected inside the fixed frame. A threaded block penetrates through the surface of the lead screw and is threadedly connected with the lead screw. The two ends of the cross bar are respectively fixedly connected to the threaded blocks on both sides, and the orientation of the cross bar is perpendicular to the adjustment grooves. An extrusion block is fixedly connected to the center of the surface of the cross bar, and the extrusion block is in contact with the side wall of the clamping block. A positioning plate and a contraction groove are respectively fixedly connected to the front and back sides at the center of the top end of the base. An electric push rod is fixedly connected to the outer side wall of the positioning plate. The telescopic end of the electric push rod penetrates through the positioning plate and is fixedly connected to a push plate. A threaded rod is rotatably connected inside the contraction groove. A contraction block penetrates through the surface of the threaded rod and is threadedly connected with the threaded rod.

[0008] In this technical solution, during the up-and-down movement of the cross bar, the extrusion block is driven to push the clamping block, clamping the left and right sides of the bearing seat. After the contraction block slides out of the contraction groove, it will cooperate with the positioning plate to fix the bearing seat from the front and back sides, thus completing the clamping and positioning of the bearing seat, facilitating subsequent processing operations, with convenient operation and strong practicability. After processing, the clamping block and the contraction block move away from the bearing seat to release the clamping of the bearing seat. Moreover, the farther the contraction groove is from the center of the base, the deeper it is. Therefore, the contraction block will gradually contract into the contraction groove during the process of moving away from the bearing seat, avoiding blocking the bearing seat. Then, the electric push rod starts to drive the push plate to push the bearing seat to move, thus pushing the bearing seat out of the base, facilitating the discharging operation, saving time, and improving the subsequent processing efficiency.

[0009] Preferably, a spring is fixedly connected between the inner side wall of one end of the adjustment groove close to the center of the base and the side wall of the slider.

[0010] Preferably, a first motor is fixedly connected to the top end of the fixed frame at one end of the cross bar, and the outer end of the transmission shaft of the first motor is fixedly connected to the top end of the lead screw.

[0011] Preferably, a second motor is fixedly connected to the outer side wall of the base on one side of the contraction groove, and the outer end of the transmission shaft of the second motor is fixedly connected to one end of the threaded rod.

[0012] Preferably, a bottom groove is formed at the bottom of the base, and a fan is fixedly connected to the opening of the bottom groove.

[0013] Preferably, the bottom groove, the adjustment groove, and the contraction groove are communicated through a plurality of ventilation holes.

[0014] Preferably, the surface of the push plate facing the center of the base and the surface of the positioning plate are on the same plane.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. The present utility model can fix the bearing seat through the adjustment groove, the clamping block, the extrusion block, the cross bar, and the contraction block. During the up-and-down movement of the cross bar, the extrusion block is driven to push the clamping block to clamp the left and right sides of the bearing seat. After the contraction block slides out of the contraction groove, it will cooperate with the positioning plate to fix the bearing seat from the front and back sides, thus completing the clamping and positioning of the bearing seat, facilitating subsequent processing operations, with convenient operation and strong practicability.

[0017] 2. The utility model facilitates the discharging of the bearing seat through the shrinkage groove, shrinkage block, electric push rod and push plate. After processing, the clamping block and the shrinkage block move away from the bearing seat to release the clamping of the bearing seat. Moreover, the shrinkage groove becomes deeper as it is farther away from the center of the base. Therefore, the shrinkage block will gradually shrink into the shrinkage groove during the process of moving away from the bearing seat, avoiding the blockage of the bearing seat. Then, the electric push rod starts to drive the push plate to push the bearing seat to move, thereby pushing the bearing seat out of the base, facilitating the discharging operation, saving time and improving the subsequent processing efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the following will be further described in conjunction with specific embodiments.

[0024] A bearing seat positioning tooling, see Figures 1 to 3, including a base 1, a cross bar 5, a positioning plate 14 and a ventilation hole 19. Adjusting grooves 7 are provided on both the left and right sides of the center of the top end of the base 1. Sliders 8 are slidably connected to the inner sides of the adjusting grooves 7, and clamping blocks 9 are fixedly connected to the top ends of the sliders 8; fixing frames 2 are fixedly connected to the four corners of the top end of the base 1. A lead screw 3 is vertically rotatably connected to the inner side of the fixing frame 2. A threaded block 4 passes through the surface of the lead screw 3 and is threadedly connected to the lead screw 3. Both ends of the cross bar 5 are fixedly connected to the threaded blocks 4 on both sides respectively, and the orientation of the cross bar 5 is perpendicular to the adjusting groove 7. An extrusion block 6 is fixedly connected to the center of the surface of the cross bar 5, and the extrusion block 6 is in contact with the side wall of the clamping block 9; a positioning plate 14 and a contraction groove 11 are respectively fixedly connected to the front and rear sides of the center of the top end of the base 1. An electric push rod 15 is fixedly connected to the outer side wall of the positioning plate 14. The telescopic end of the electric push rod 15 passes through the positioning plate 14 and is fixedly connected to a push plate 16. A threaded rod 12 is rotatably connected to the inner side of the contraction groove 11. A contraction block 13 passes through the surface of the threaded rod 12 and is threadedly connected to the threaded rod 12. By providing the contraction groove 11 to accommodate the contraction block 13, while facilitating the clamping of the bearing seat, it can retract below the surface of the base 1 when the bearing seat is discharged, thus not blocking the bearing seat and facilitating the discharge of the bearing seat. And there is no cumbersome clamping and positioning structure, and the overall operation is relatively convenient and easy.

[0025] Specifically, as Figure 3 shown, a spring 10 is fixedly connected between the inner side wall of one end of the adjusting groove 7 close to the center of the base 1 and the side wall of the slider 8. After the extrusion block 6 rises, the clamping block 9 loses the push, so the spring 10 will push the slider 8 and the clamping block 9 away from the center of the base 1 for reset, facilitating the subsequent placement of the bearing seat and the extrusion of the extrusion block 6.

[0026] It is worth noting that, as Figure 1 shown, a first motor 301 is fixedly connected to the top end of the fixing frame 2 at one end of the cross bar 5. The outer end of the transmission shaft of the first motor 301 is fixedly connected to the top end of the lead screw 3. After the first motor 301 is started, it will drive the lead screw 3 to rotate, causing the threaded block 4 to rise and fall. During the rising and falling process of the threaded block 4, it will drive the cross bar 5 and the extrusion block 6 to rise and fall, and the extrusion block 6 will push the clamping block 9 to move along the adjusting groove 7, thereby clamping and releasing the bearing seat.

[0027] It is worth noting that, as Figure 2 shown, a second motor 121 is fixedly connected to the outer side wall of the base 1 on one side of the contraction groove 11. The outer end of the transmission shaft of the second motor 121 is fixedly connected to one end of the threaded rod 12. After the second motor 121 is started, it drives the threaded rod 12 to rotate, causing the contraction block 13 to move along the threaded rod 12. When the contraction block 13 approaches the center side of the base 1, it will gradually rise, and when it moves away from the center side of the base 1, it will gradually retract, thus facilitating the clamping of the bearing seat and not blocking during discharging.

[0028] It should be noted that, as Figure 2 shown, a bottom groove 17 is formed at the bottom of the base 1, and a fan 18 is fixedly connected to the opening of the bottom groove 17.

[0029] It should be noted that, as Figure 2 and Figure 3 shown, the bottom groove 17, the adjustment groove 7 and the contraction groove 11 are communicated through a plurality of ventilation holes 19. After the fan 18 is started, it will draw air upward, so that the air flow blows along the ventilation holes 19, and the processed particle debris in the adjustment groove 7 and the contraction groove 11 is blown out, which is convenient for cleaning.

[0030] It should be noted that, as Figure 2 shown, the surface of the push plate 16 facing the center of the base 1 and the surface of the positioning plate 14 are on the same plane. Therefore, the push plate 16 will not affect the normal positioning ability of the positioning plate 14. When the electric push rod 15 is retracted to the shortest, the push plate 16 will completely fit with the positioning plate 14.

[0031] During actual use, the bearing seat is placed at the center of the top of the base 1 and abuts against the positioning plate 14 for positioning. Through the adjustment groove 7, the clamping block 9, the extrusion block 6, the cross bar 5 and the contraction block 13, the bearing seat can be fixed. When the cross bar 5 moves up and down, it drives the extrusion block 6 to push the clamping block 9 to clamp the left and right sides of the bearing seat, and after the contraction block 13 slides out of the contraction groove 11, it cooperates with the positioning plate 14 to fix the bearing seat from the front and back sides, thus completing the clamping and positioning of the bearing seat, facilitating subsequent processing operations, with convenient operation and strong practicability. At the same time, through the contraction groove 11, the contraction block 13, the electric push rod 15 and the push plate 16, it is convenient to discharge the bearing seat. After processing, the clamping block 9 and the contraction block 13 move away from the bearing seat to release the clamping of the bearing seat, and the contraction groove 11 is deeper at the place farther from the center of the base 1. Therefore, the contraction block 13 will gradually contract into the contraction groove 11 during the process of moving away from the bearing seat, avoiding the occlusion of the bearing seat. Then the electric push rod 15 is started to drive the push plate 16 to push the bearing seat to move, so as to push the bearing seat out of the base 1, facilitating the discharging operation, saving time and improving the subsequent processing efficiency.
