[0022] Please see Figures 1-3 It is a multi-vehicle type clamp switching device 100 provided by an embodiment of the utility model.

[0023] The multi-vehicle type clamp switching device 100 includes a fixed base 20, a movable mechanism 40 switchably matched with the fixed base 20 along the assembly direction, and a locking mechanism 60 for positioning and locking the movable mechanism 40 and the fixed base 20, and the locking mechanism 60 can be detachably connected with the fixed base 20 and the movable mechanism 40. The multi-vehicle type clamp switching device 100 switches different movable mechanisms 40 to adapt to different vehicle type clamps, which is convenient for processing and assembling different vehicle types, saves the cost budget, saves the working space utilization rate, and meets the requirements of modern automatic production.

[0024] It can be understood that when the locking mechanism 60 is in the locked state, the fixed base 20 and the movable mechanism 40 are positioned and locked, which is convenient for processing and operating the vehicle type; when the locking mechanism 60 is in the unlocked state, the movable mechanism 40 can move relative to the fixed base 20.

[0025] In one embodiment, the movable mechanism 40 comprises a clamp platform 41, a roller assembly 42 arranged below the clamp platform 41, and a guide wheel assembly 43; switching different movable mechanisms 40 is equivalent to switching different clamp platforms 41, so that different vehicle models can be clamped and fixed for processing operation. The fixed base 20 comprises a bottom plate 21 and guide plates 22 arranged on both sides of the bottom plate 21, the roller assembly 42 and the guide wheel assembly 43 are located outside the guide plates 22, and the guide wheel assembly 43 abuts against the outer side of the guide plates 22. The space outside the fixed base 20 is fully utilized for manual maintenance and adjustment.

[0026] In combination Figures 4-6 As shown in the drawings, the bottom plate 21 is a horizontal plate, and the guide plates 22 are vertical plates. The guide plates 22 extend along the assembly direction. In the embodiments of the present application, the assembly direction can also be understood as the front-rear direction. The direction in which the movable mechanism 40 approaches the fixed base 20 to combine with the fixed base 20 is forward, and the direction in which the movable mechanism 40 moves away from the fixed base 20 to separate from the fixed base 20 is backward. The guide plates 22 are arranged on both sides of the bottom plate along the left-right direction, and the left-right direction and the front-rear direction are horizontal directions and perpendicular to each other.

[0027] The guide plates 22 comprise straight guide plates 221 located in front along the assembly direction and arc-shaped guide plates 222 located at the rear. In combination Figure 4 As shown in the drawings, it can be understood that when the movable mechanism 40 is assembled towards the fixed base 20, the arc-shaped guide plates 222 are located at the rear, which are used to preferentially contact the movable mechanism 40 to play an initial guiding role.

[0028] In one embodiment, the guide wheel assembly 43 comprises at least two guide wheels 431 arranged along the assembly direction, and the center direction of the guide wheels 431 is along the vertical direction. At least one guide wheel 431 is located in front of the roller assembly 42 to preferentially abut against the guide plates 22.

[0029] In combination Figure 7 As shown in the drawings, the rolling surface of the guide wheels 431 contacts the outer side of the guide plates 22, and the guide wheels 431 roll along the outer side of the guide plates 22 to provide a clear path limit for the movement of the movable mechanism 40, which ensures that the movable mechanism 40 moves along the predetermined assembly direction.

[0030] In specific embodiments, the bottom plate 21 is provided with guide plates 22 on both sides in the left-right direction, and the movable mechanism 40 is also provided with a guide wheel assembly 43 and a roller assembly 42 on both sides of the clamp platform 41, and the guide wheel assembly 43 on each side is in rolling cooperation with a guide plate 22 respectively, so as to guide the assembly of the movable mechanism 40 and the fixed base 20 in the assembly direction, prevent the movable mechanism 40 from deviating in the left-right direction, and enhance the stability and accuracy of movement.

[0031] During assembly, the guide wheels 431 of the guide wheel assemblies 43 sequentially contact the guide plates 22 forward, and at least one guide wheel 431 is arranged to contact the guide plates 22 before the roller assembly 42, so as to prevent the roller assembly 42 from colliding with the fixed base 20. When the guide wheels 431 move forward, they first abut against the arc-shaped guide plates 222, and after continuing to move forward, they stably abut against the straight guide plates 221, thereby playing a role of guiding and limiting.

[0032] Considering that the guide plates 22 are often contacted and collided, they need to have high fatigue resistance and impact resistance, and the guide plates 22 are made of 45 steel, which has high and uniform surface hardness after quenching, good wear resistance and high fatigue resistance.

[0033] In one embodiment, the fixed base 20 includes a first reinforcing column 23 extending upward from the bottom plate 21, a first mounting plate 24 arranged at the top of the first reinforcing column 23, and the guide plate 22 is connected to the outer side edge of the first mounting plate 24.

[0034] In combination with Figures 4-6 As shown, the fixed base 20 includes at least four first reinforcing columns 23 arranged at the corners of the bottom plate 21, and in the assembly direction, the same guide plate 22 is connected to two first reinforcing columns 23 located on the same side, that is, the length of the guide plate 22 in the assembly direction basically covers the bottom plate 21.

[0035] In combination with Figures 8-10 As shown, the movable mechanism 40 includes a second reinforcing column 44 extending downward from the clamp platform 41, a second mounting plate 45 arranged at the bottom of the second reinforcing column 44, and the roller assembly 42 and part of the guide wheel assembly 43 are mounted on the second mounting plate 45.

[0036] The movable mechanism 40 at least includes four second reinforcing columns 44 corresponding to the first reinforcing columns 23. Each of the first reinforcing columns 23 corresponds to a second reinforcing column 44 in the vertical direction. It can be understood that the fixed base 20 also includes four first mounting plates 24 respectively arranged on the first reinforcing columns 23, and the movable mechanism 40 also includes four second mounting plates 45 respectively arranged on the second reinforcing columns 44. Among them, the first mounting plate 24 is located below the second mounting plate 45, and the first mounting plate 24 and the second mounting plate 45 are spaced apart by a distance.

[0037] The multi-vehicle type clamp switching device includes four roller assemblies 42 respectively mounted on the second mounting plate 45, which is conducive to the balanced and stable movement of the movable mechanism 40. The multi-vehicle type clamp switching device includes six guide wheel assemblies 43 arranged on both sides of the clamp platform 41. Four of the guide wheel assemblies are also mounted on the second mounting plate 45, and the guide wheel assembly 43 is located in front of the roller assembly 42 on the same second mounting plate 45. Among them, the other two guide wheel assemblies 43 are arranged at the middle of the two guide wheel assemblies 43 on each side. The other two guide wheels 43 can be directly connected and fixed to the clamp platform 41.

[0038] The multi-vehicle type clamp switching device includes heavy-duty universal wheels respectively mounted on the surface of the first mounting plate 24 facing the second mounting plate 45, which ensures that the height of each clamp platform 41 falling on the fixed base 20 is consistent, facilitating unified machining operation by external equipment.

[0039] In one embodiment, the locking mechanism 60 includes a stop block 61 arranged on the fixed base 20 and a limiting block 62 arranged on the movable mechanism 40, and the limiting block 62 abuts and stops on the stop block 61 in the assembly direction. It can be understood that when the movable mechanism 40 is assembled into the fixed base 20 in the assembly direction, there must be a final position, and the cooperation of the stop block 61 and the limiting block 62 is to realize the timely stop of the movable mechanism 40 in the assembly direction.

[0040] More specifically, the stop block 61 is mounted on one side of the first mounting plate 24 close to the second mounting plate 45, and the limiting block 62 is mounted on one side of the second mounting plate 45 close to the first mounting plate 24.

[0041] The locking mechanism 60 includes a gasket detachably arranged on the limiting block 62, which is used to adjust the final position of the movable mechanism 40 assembled into the fixed base 20 in the assembly direction. If the position of the movable mechanism 40 deviates during pushing, the design of the limiting block 62 allows fine adjustment by adding or adjusting a gasket with a thickness of about 5mm. This adjustment method can quickly correct the final position of the movable mechanism 40, making it more accurate and stable to fall in the correct position.

[0042] In specific embodiments, the gasket is arranged on the limiting block 62, facilitating corresponding adjustment of the limiting block 62 and the gasket when the movable mechanism 40 is switched.

[0043] In one embodiment, the two first reinforcing columns 23 located in front along the assembly direction are used to mount the stop block 61, and the two second reinforcing columns 44 located in front along the assembly direction are used to mount the limiting block 62, which is in abutting fit along the assembly direction. It can be understood that the movable mechanism 40 is necessarily pushed forward to gradually combine with the fixed base 20, and the positions of the stop block 61 and the limiting block 62 should be arranged close to the front, so as to ensure that the movable mechanism 40 stops only after moving to the correct position.

[0044] In one embodiment, the locking mechanism 60 includes a detachable locking piece 63 used to lock the first mounting plate 24 and the second mounting plate 45. After the movable mechanism 40 reaches the final correct position, it should be further locked and positioned to ensure the accuracy of the position of the clamp platform 41 during actual processing.

[0045] The detachable locking piece 63 can be selected as a bolt, and the first mounting plate 24 and the second mounting plate 45 are correspondingly provided with bolt holes, and the bolt passes through the bolt holes to lock and connect the first mounting plate 24 and the second mounting plate 45. In actual production, workers only need to push the clamp platform 41 to be switched to the initially determined final correct position and insert the bolt, so that the mechanism cost is low and the worker efficiency is high.

[0046] Specifically, at least two detachable locking pieces 63 lock the two first mounting plates 24 and the second mounting plates 45 located at the rear along the assembly direction, respectively. It can be understood that the first mounting plate 24 and the second mounting plate 45 located in front are provided with the stop block 61 and the limiting block 62. The locking piece 63 is arranged close to the rear to facilitate worker operation. And the position of the locking mechanism 60 is reasonably arranged without occupying other space.

[0047] The locking mechanism 60 is mounted and fixed to the inner side of the first mounting plate 24 and the second mounting plate 45, and the roller assembly 42 and the guide wheel assembly 43 are mounted and fixed to the outer side of the second mounting plate 45. The locking mechanism 60 and the roller assembly 42 are compactly but reasonably arranged at the corresponding corners of the bottom plate 21, improving the space utilization rate. And the detachable locking piece 63 is close to the rear to facilitate manual operation, and the guide wheel assembly 43 and the roller assembly 42 are also located on the outer side to facilitate manual maintenance and adjustment.

[0048] The locking mechanism 60 includes a sensor 64 disposed between the base plate 21 and the first mounting plate 24, which is used to detect whether the detachable locking piece 63 is in place. The sensor 64 detects the detachable locking piece 63, and a signal such as a light is generated, thereby proving that the clamp platform 41 is switched.

[0049] The beneficial effects of the utility model lie in that the multi-vehicle-type clamp switching device 100 switches different movable mechanisms 40 to adapt to clamp platforms 41 of different vehicle types, facilitating machining and assembly of different vehicle types; the roller assembly 42 and the guide wheel assembly 43 are located on the outer side of the guide plate 22, and the guide wheel assembly 43 abuts against the outer side of the guide plate 22 inwardly, thereby fully utilizing the space on the outer side of the fixed base 20 and facilitating manual maintenance and adjustment.
