Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figures 1-4 ,in, Figure 1 A front sectional view of a preferred embodiment of the oil pump cover shaft press-fitting device provided by this utility model; Figure 2 An assembly drawing of the rectangular block, rectangular base, and insert rod provided for this utility model; Figure 3 Assembly drawing of the connecting rod, connecting rod and arc-shaped clamp provided for this utility model; Figure 4 This is an assembly drawing of the clamping mechanism provided by this utility model. The oil pump cover shaft press-fitting device includes: a press-fitting device 1, which comprises: an operating table, a bracket 2, a connecting plate 3, a press head 4, a hydraulic cylinder 5, and a press seat 19. The bracket 2 is mounted on the operating table 1, the connecting plate 3 is disposed inside the bracket 2, the press head 4 is disposed below the connecting plate 3, the hydraulic cylinder 5 is fixedly mounted on the bracket 2, and the output rod of the hydraulic cylinder 5 is fixedly connected to the connecting plate 3. The press seat 19 is mounted on the operating table, and the press seat 19 is located directly below the press head 4; a rectangular block 6 is fixedly mounted on the bottom of the connecting plate 3; and a rectangular block 6 is mounted on the press head 4. The press head 4 has a rectangular seat 7 that is plugged into and engaged with the rectangular block 6 at its top; a plug rod 8 that is inserted into one side of the rectangular seat 7 and slides through the rectangular block 6; a reinforcing mechanism on the plug rod 8 for fixing the plug rod 8 to the rectangular seat 7; and a clamping mechanism on the operating table 1 for fixing the cover shaft to the press base 19. Through the reasonable layout of the press equipment 1, the stability of the press process is ensured. By adopting the plugging and engaging of the rectangular block 6 and the rectangular seat 7, combined with the plug rod 8 and the reinforcing mechanism, the press head 4 is easy to replace, improving production efficiency. The clamping mechanism firmly fixes the cover shaft, preventing workpiece displacement during the press process and ensuring assembly accuracy.

[0025] The rectangular seat 7 has a sealing gasket 9 in the groove to prevent the rectangular block 6 from being positioned. The sealing gasket 9 is in close contact with the rectangular block 6. The tight contact between the sealing gasket 9 in the groove of the rectangular seat 7 and the rectangular block 6 prevents the pressure head 4 from loosening due to vibration or gaps during operation, thereby improving the stability of the pressing.

[0026] The reinforcement mechanism includes: a mounting groove 10 formed at the top of the insertion rod 8; a return spring 11 fixedly installed in the mounting groove 10; and a positioning block 12 installed at the top of the return spring 11 to limit the insertion rod 8. One side of the positioning block 12 contacts the rectangular seat 7. By using the return spring 11 and positioning block 12 in the reinforcement mechanism, the insertion rod 8 is automatically locked after insertion to prevent accidental dislodgement and ensure that the pressure head 4 is firmly installed. The insertion rod 8 can be unlocked by pressing down the positioning block 12. The operation is simple and facilitates quick replacement of the pressure head 4.

[0027] A guide rod 13 is mounted on the bracket 2 to guide the smooth movement of the connecting plate 3. The guide rod 13 is slidably connected to the connecting plate 3. A guide block 14 is slidably sleeved on the guide rod 13. A connecting rod 15 is mounted on the guide block 14. A connecting rod 16 is fixedly mounted on one side of the rectangular seat 7. The connecting rod 16 is connected to the slot of the connecting rod 15. An arc-shaped locking rod 17 is rotatably mounted on one side of the connecting rod 15 to connect the connecting rod 16 and the connecting rod 15. The arc-shaped locking rod 17 rotatably passes through the connecting rod 16 and the connecting rod 15. The cooperation of the guide rod 13 and the guide block 14 makes the connecting plate 3 move smoothly, avoids the pressure head 4 from tilting, and improves the pressing accuracy. The connecting rod 16 and the connecting rod 15 are locked by the arc-shaped locking rod 17, which enhances the connection strength between the pressure head 4 and the drive mechanism and prevents loosening during pressing.

[0028] Both the connecting rod 15 and the arc-shaped clamping rod 17 are equipped with magnetic strips 18 for fixing the arc-shaped clamping rod 17. The two magnetic strips 18 attract each other, and the arc-shaped clamping rod 17 is kept locked by the attraction of the magnetic strips 18, which prevents vibration from causing loosening and improves the reliability of equipment operation.

[0029] The clamping mechanism includes: a mounting frame 20 fixedly mounted on the operating table; a bidirectional screw 21 rotatably mounted on the mounting frame 20; sliders 22 threaded onto the bidirectional screw 21; clamping blocks 23 respectively disposed on the two sliders 22 for clamping and fixing the cover shaft, each of the two clamping blocks 23 having an arc-shaped notch on one side; a motor 24 fixedly mounted on one side of the mounting frame 20 for driving the bidirectional screw 21 to rotate, the output shaft of the motor 24 being fixedly connected to the bidirectional screw 21; and an anti-slip pad 25 disposed in the arc-shaped notch of the clamping block 23. The bidirectional screw 21 drives the sliders 22 and clamping blocks 23 to move synchronously, thereby achieving automatic clamping of the cover shaft and improving production efficiency.

[0030] A fixing block 26 is fixedly installed on one side of the slider 22, and a fixing seat 27 is fixedly installed on one side of the clamping block 23. The fixing seat 27 is plugged into the fixing block 26. A screw rod 28 is threaded onto the fixing seat 27. The screw rod 28 is threaded through the fixing block 26. The fixing block 26 and the fixing seat 27 are fixed together by the screw rod 28, which facilitates the replacement of different models of clamping blocks 23 and adapts to various workpiece requirements.

[0031] It is worth noting that the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0032] The working principle of the oil pump cover shaft press-fitting device provided by this utility model is as follows:

[0033] This solution also includes an electrical control cabinet, which is installed on the equipment. During use, each piece of electrical equipment can be started and operated separately through the electrical control cabinet. The power connection method of each piece of electrical equipment is an existing mature technology and is well known to those in the field, so it will not be described in detail here.

[0034] In use, firstly, the cover shaft component to be pressed is placed on the pressing base 19 by a feeding mechanism (such as a robot). Then, the motor 24 is started, and the motor 24 drives the bidirectional screw 21 to rotate, so that the two sliders 22 move synchronously towards each other along the mounting frame 20, driving the clamping blocks 23 to approach the cover shaft. The arc-shaped notches of the two clamping blocks 23 fit against the outer wall of the cover shaft, and the friction is enhanced by the anti-slip pads 25 to ensure that the cover shaft does not shift or loosen during the pressing process.

[0035] After the cover shaft is fixed, the hydraulic cylinder 5 is started. The output rod of the hydraulic cylinder 5 pushes the connecting plate 3 to move smoothly down along the guide rod 13, which drives the pressure head 4 to descend vertically. During the descent of the pressure head 4, the guide block 14 slides synchronously along the guide rod 13 with the connecting rod 15 to ensure the stability of the movement trajectory of the pressure head 4 and avoid deviation. Since the connecting rod 15 and the connecting rod 16 are locked by the arc-shaped clamp 17 and reinforced by the magnetic strip 18, the rigid fit between the pressure head 4 and the reinforcement mechanism is further guaranteed.

[0036] When the pressure head 4 contacts the cover shaft, the hydraulic cylinder 5 continuously applies pressure to complete the precision pressing of the cover shaft and the oil pump housing. After pressing, the hydraulic cylinder 5 retracts, driving the pressure head 4 to reset. The clamping mechanism then releases the cover shaft via the reverse rotation of the motor 24, completing one work cycle. Throughout the process, the coordinated action of the guide rod 13, the reinforcement mechanism, and the clamping mechanism ensures high precision, high efficiency, and repeatability of the pressing process.

[0037] When the pressure head 4 needs to be replaced, first rotate the arc-shaped locking rod 17 to disengage it from the slots of the connecting rod 16 and the connecting rod 15, and at the same time separate the magnetic strip 18 from its attraction. Then press down the positioning block 12 on the top of the insertion rod 8 to compress the return spring 11 and retract it into the mounting groove 10. The insertion rod 8 can then be pulled out from the rectangular seat 7, releasing the insertion and fixing of the rectangular block 6 and the rectangular seat 7. At this time, the restriction of the pressure head 4 is completely released, and it can be removed from the rectangular seat 7. Replace it with a pressure head of the appropriate model. Since the groove of the rectangular seat 7 is equipped with a sealing gasket 9, after replacement, it can effectively seal the gap between the rectangular block 6 and the rectangular seat 7, preventing instability caused by vibration or displacement during pressing. After replacing the pressure head 4, remove the screw rod 28, and then replace the clamping block 23 to facilitate the fixing of different models of cover shafts.

[0038] Compared with related technologies, the oil pump cover shaft press-fitting device provided by this utility model has the following advantages:

[0039] This utility model provides an oil pump cover shaft press-fitting device. Through the reasonable layout of the press-fitting equipment 1, the stability of the press-fitting process is ensured. The insertion and extraction of rectangular blocks 6 and rectangular seats 7, combined with the insertion rod 8 and reinforcing mechanism, makes it easy to replace the press head 4, improving production efficiency. The clamping mechanism firmly fixes the cover shaft, preventing workpiece displacement during press-fitting and ensuring assembly accuracy. The sealing gasket 9 in the groove of the rectangular seat 7 is in close contact with the rectangular block 6, preventing loosening of the press head 4 due to vibration or gaps during operation, thus improving press-fitting stability. The reinforcing mechanism, designed with a return spring 11 and a positioning block 12, automatically locks the insertion rod 8 after insertion, preventing accidental dislodgement and ensuring the press head 4 is securely installed. The insertion rod 8 can be unlocked by pressing down the positioning block 12. Simple to operate and easy to quickly replace the pressure head 4, the connecting plate 3 moves smoothly through the cooperation of the guide rod 13 and the guide block 14, preventing the pressure head 4 from tilting and improving the pressing accuracy. The connecting rod 16 and the connecting rod 15 are locked by the arc-shaped clamp 17, which enhances the connection strength between the pressure head 4 and the drive mechanism and prevents loosening during pressing. The magnetic strip 18 keeps the arc-shaped clamp 17 locked, preventing loosening due to vibration and improving the reliability of equipment operation. The bidirectional screw 21 drives the slider 22 and the clamping block 23 to move synchronously, realizing automatic clamping of the cover shaft and improving production efficiency. The fixing block 26 and the fixing seat 27 are fixed by the plug-in cooperation and the screw rod 28, which facilitates the replacement of different models of clamping blocks 23 to meet the needs of various workpieces.
