[0001] This utility model relates to the field of vehicle chassis drive shaft rear cover assembly technology, specifically a device for press-fitting drive shaft rear covers. Background Technology
[0002] Currently, the assembly process of the rear cover of the drive shaft of special vehicles mainly relies on assembly personnel to operate with simple tools such as hammers. However, this traditional operation mode not only leads to high labor intensity for assembly personnel, but also low work efficiency, long time consumption, and inability to effectively control the pressing quality. Summary of the Invention
[0003] To overcome the shortcomings of the existing technology, the purpose of this invention is to provide a device for pressing a drive shaft rear cover, so as to improve the efficiency and quality of pressing operations and reduce the labor intensity of assembly personnel.
[0004] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:
[0005] A device for press-fitting a drive shaft rear cover includes a worktable, a support leg fixedly connected to the bottom of the worktable, a first mounting plate fixedly connected to the upper surface of the worktable, a first column fixedly connected to the upper surface of the first mounting plate, a second mounting plate fixedly connected to the upper surface of the first column, a mounting hole provided inside the second mounting plate, a hydraulic push rod fixedly connected to the inner wall of the mounting hole, a pressure block fixedly connected to the bottom of the hydraulic push rod, a third mounting plate fixedly connected to the upper surface of the worktable, a second column fixedly connected to the upper surface of the third mounting plate, a support frame fixedly connected to the upper surface of the second column, and a groove provided on the front side of the support frame.
[0006] Furthermore, two pads are fixedly connected to the upper surface of the support frame, and the two pads are located on the left and right sides of the groove, respectively.
[0007] Furthermore, a hollow cylinder is fixedly connected to the bottom of the support frame, a trapezoidal block is fitted to the inner wall of the hollow cylinder, an arc-shaped groove is formed on one side of the trapezoidal block, a spring is fixedly connected to the other side of the trapezoidal block, a baffle is fixedly connected to one end of the spring, the upper surface of the baffle is fixedly connected to the bottom of the support frame, a rectangular hole is formed at the bottom of the hollow cylinder, a slider is fitted to the inner wall of the rectangular hole, the upper surface of the slider is fixedly connected to the bottom of the trapezoidal block, a connecting block is fixedly connected to the bottom of the hollow cylinder, and an electromagnet is fixedly connected to the side of the connecting block.
[0008] Furthermore, the length of the slider is less than the length of the rectangular hole, and the height of the slider is greater than the thickness of the hollow cylinder.
[0009] Furthermore, the electromagnet is located between the slider and the connecting block, and the center of the electromagnet and the center of the slider are on the same horizontal line.
[0010] Furthermore, the front of the groove is open, and the groove is located below the pressure block.
[0011] Compared with the prior art, this utility model has the following advantages:
[0012] 1. This utility model can support and position the drive shaft through the support frame and groove. At the same time, when the hydraulic push rod controls the pressure block to move downward, the pressure block will apply downward pressure to the rear cover on the drive shaft, and automatically install the rear cover on the ball cage through pressure. This can effectively reduce the workload of assembly personnel and improve the assembly efficiency of the drive shaft rear cover.
[0013] 2. This utility model uses the elastic force of the spring to ensure that after the drive shaft is placed in the groove, the arc-shaped groove can automatically contact the drive shaft. At the same time, when the electromagnet is opened, the attraction of the electromagnet to the slider prevents the trapezoidal block from sliding in the hollow cylinder. The position of the arc-shaped groove on the trapezoidal block and the drive shaft will not shift, so that when sealing the cap after pressing, the pressing will not fail due to the shift of the drive shaft position.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the device for pressing a transmission shaft rear cover according to the present invention includes a workbench 1, a support leg 2 fixedly connected to the bottom of the workbench 1, a first mounting plate 3 fixedly connected to the upper surface of the workbench 1, a first column 4 fixedly connected to the upper surface of the first mounting plate 3, a second mounting plate 5 fixedly connected to the upper surface of the first column 4, a mounting hole 6 opened inside the second mounting plate 5, a hydraulic push rod 7 fixedly connected to the inner wall of the mounting hole 6, a pressure block 8 fixedly connected to the bottom of the hydraulic push rod 7, a third mounting plate 9 fixedly connected to the upper surface of the workbench 1, a second column 10 fixedly connected to the upper surface of the third mounting plate 9, a support frame 11 fixedly connected to the upper surface of the second column 10, and a groove 12 opened on the front side of the support frame 11.
[0027] Among them, the upper surface of the support frame 11 is fixedly connected with two pads 13, and the two pads 13 are located on the left and right sides of the groove 12 respectively. The front of the groove 12 is open, and the groove 12 is located below the pressure block 8.
[0028] It should be noted that the hydraulic push rod 7 controls the pressure block 8 to move up or down. When the drive shaft is placed in the groove 12, the groove 12 positions the drive shaft and the support frame 11 supports the drive shaft. At the same time, by setting a non-metallic pad 13 on the support frame 11, when the drive shaft is placed in the groove 12, the ball cage on the drive shaft contacts the pad 13. At this time, the pad 13 prevents the surface of the drive shaft from being damaged when it is sealed after pressing.
[0029] A hollow cylinder 14 is fixedly connected to the bottom of the support frame 11. A trapezoidal block 15 is fitted to the inner wall of the hollow cylinder 14. An arc groove 16 is opened on one side of the trapezoidal block 15. A spring 17 is fixedly connected to the other side of the trapezoidal block 15. A baffle 18 is fixedly connected to one end of the spring 17. The upper surface of the baffle 18 is fixedly connected to the bottom of the support frame 11. A rectangular hole 19 is opened at the bottom of the hollow cylinder 14. A slider 20 is fitted to the inner wall of the rectangular hole 19. The upper surface of the slider 20 is fixedly connected to the bottom of the trapezoidal block 15. A connecting block 21 is fixedly connected to the bottom of the hollow cylinder 14. An electromagnet 22 is fixedly connected to the side of the connecting block 21.
[0030] The length of slider 20 is less than the length of rectangular hole 19, the height of slider 20 is greater than the thickness of hollow cylinder 14, and electromagnet 22 is located between slider 20 and connecting block 21. The center of electromagnet 22 and the center of slider 20 are on the same horizontal line.
[0031] It should be noted that the hollow cylinder 14 allows the trapezoidal block 15 to move only left and right. The cooperation between the slider 20 and the rectangular hole 19 prevents the trapezoidal block 15 from separating from the hollow cylinder 14. When the drive shaft is inserted into the groove 12, the inclined surface on the trapezoidal block 15 causes the distance between the two trapezoidal blocks 15 to automatically increase as the drive shaft enters the groove 12. When the drive shaft is aligned with the arc groove 16, the elastic force of the spring 17 causes the arc groove 16 to contact the drive shaft. At the same time, the electromagnet 22 is energized and opened. The attraction of the electromagnet 22 to the slider 20 prevents the trapezoidal block 15 from sliding inside the hollow cylinder 14. The position of the arc groove 16 on the trapezoidal block 15 and the drive shaft will not shift. Therefore, when sealing the cap after pressing, the shift in the position of the drive shaft will not cause pressing failure.
[0032] The working principle of this utility model is as follows: First, the pressure block 8 is moved to the highest point by the hydraulic push rod 7. Then, the drive shaft is placed in the groove 12. At this time, the inclined surface on the trapezoidal block 15 allows the distance between the two trapezoidal blocks 15 to automatically increase when the drive shaft enters the groove 12. When the drive shaft is aligned with the arc groove 16, the elastic force of the spring 17 makes the arc groove 16 contact the drive shaft. Then, the electromagnet 22 is turned on. The attraction of the electromagnet 22 to the slider 20 prevents the trapezoidal block 15 from sliding in the hollow cylinder 14. The position of the arc groove 16 on 15 and the drive shaft will not be offset. Then, the rear cover is placed on the drive shaft, and the pressure block 8 is moved downward by the hydraulic push rod 7. At this time, the pressure block 8 will apply downward pressure to the rear cover on the drive shaft, and automatically install the rear cover on the ball cage by the pressure. After the rear cover is installed, the pressure block 8 is returned to the highest point by the hydraulic push rod 7, and the electromagnet 22 is turned off, so that the electromagnet 22 is de-energized. At this time, since the trapezoidal block 15 can move freely in the hollow cylinder 14, the drive shaft can be directly removed from the groove 12.
[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
