Description

Technical Field

[0001] This invention relates to the field of automobile manufacturing technology, specifically to a telescopic skid and a method for producing different car models. Background Technology

[0002] To adapt to market changes, car manufacturers need to adjust the production of different models in a timely manner to meet market demands. Therefore, the production line needs to be compatible with a large number of models, especially in some production lines with different sizes of models and large differences in body length. When designing the skid length, it is necessary to take into account the longest model, resulting in a larger skid length.

[0003] Based on the actual job requirements in the production line, steps need to be set in front of and behind the skid for manual workers to stand on. However, steps are not needed in the automatic work area and storage area. Since the length of the car models is different, the length of the steps on the skid needs to be adapted to different car models. Therefore, the step design has a large coverage length. When producing small car models, there will be redundancy in the length of the skid, which will affect the production cycle and is not conducive to improving efficiency and saving energy. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a skid with a telescopic step, which can be produced according to different types of vehicle models, and the extension or retraction of the step can be controlled to change the length of the skid, thereby improving production efficiency and effectively solving the problems in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a telescopic skid, comprising:

[0006] Skid body;

[0007] Telescopic platforms are symmetrically arranged on the upper left and right sides of the skid body;

[0008] The slide rail is fixed at one end to the skid body and slidably connected to the telescopic platform at the other end.

[0009] The locking mechanism is symmetrically arranged on the front and rear sides of each telescopic step to fix the position of the telescopic step.

[0010] The locking drive device is symmetrically arranged on the first support platform on both sides of the skid moving track, and is located below the locking mechanism;

[0011] The telescopic drive mechanism is symmetrically arranged on the second support platform on both sides of the skid's moving track, and is used to drive the telescopic platform to move back and forth on the slide rail.

[0012] As a preferred embodiment of the present invention, the telescopic platform includes a platform and a positioning plate. There are two positioning plates, which are symmetrically arranged on both sides of the platform. The positioning plates have a plurality of holes evenly distributed along their length.

[0013] As a preferred embodiment of the present invention, the locking mechanism includes a movable rod, a housing, a fixed plate, a spring, an end plate, and a locking pin. The housing is fixed to one side of the skid. The upper end of the movable rod passes through the housing and is connected to the end plate. The locking pin is fixed to the lower end of the end plate. The locking pin cooperates with a hole on the positioning plate. A fixed plate is provided on the outer side of the movable rod inside the housing. A spring is provided between the fixed plate and the top of the housing.

[0014] As a preferred embodiment of the present invention, the locking drive device includes a first cylinder and a top plate, the first cylinder being disposed on a first support platform, and the top plate being fixed on the telescopic rod of the first cylinder.

[0015] As a preferred embodiment of the present invention, the telescopic drive mechanism includes a second cylinder, a trolley, a pusher head, and a track. The second cylinder is mounted on a second support platform, and the telescopic rod of the second cylinder is connected to the trolley. The trolley moves within the track, and a rotatable pusher head is provided on one side of the trolley for pushing the telescopic platform to move.

[0016] As a preferred embodiment of the present invention, the skid body is provided with a stop bar for limiting the rotation angle of the pusher head.

[0017] As a preferred embodiment of the present invention, one end of the pusher is rotatably connected to the trolley via a pin, and the pusher has a V-shaped structure.

[0018] A method for producing different vehicle models using telescopic skids includes:

[0019] When producing large vehicles, the telescopic steps at both ends of the skid extend at the transition position at the entrance of the manual work station and retract at the exit of the manual work station.

[0020] When producing small vehicles, the telescopic steps at both ends of the skid are kept in the retracted state, and all telescopic steps in the storage area are kept in the retracted state.

[0021] Compared with the prior art, the beneficial effects of the present invention are: the telescopic skid and the method for producing different models are reasonably designed and ingeniously conceived.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments (for ease of description and understanding, the following refers to...). Figure 1(The above is described above). Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present invention.

[0038] Please see Figure 1-6 The present invention provides a technical solution: a telescopic skid, comprising a skid body 1, a telescopic step 2, a slide rail 3, a locking mechanism 4, a locking drive device 5, and a telescopic drive mechanism 6, wherein one end of the slide rail 3 is fixed to the skid body 1, and the other end is slidably connected to the telescopic step 2.

[0039] The telescopic platform 2 is symmetrically arranged on the left and right sides of the upper end of the skid 1. The telescopic platform 2 includes a platform 21 and a positioning plate 22. There are two positioning plates 22, which are symmetrically arranged on both sides of the platform 21. The positioning plates 22 have several holes 23 evenly distributed along their length. Depending on the vehicle model of different length, the locking pin 46 can be inserted into the holes 23 at different positions, so that the telescopic platform 2 can stop at different positions.

[0040] like Figure 7-8 The locking mechanism 4 is symmetrically arranged on the front and rear sides of each telescopic step 2. The locking mechanism 4 includes a movable rod 41, a housing 42, a fixed plate 43, a spring 44, an end plate 45, and a locking pin 46. The housing 42 is fixed to one side of the skid 1. The upper end of the movable rod 41 passes through the housing 42 and is connected to the end plate 45. The locking pin 46 is fixed to the lower end of the end plate 45. The locking pin 46 cooperates with the insertion hole 23 on the positioning plate 22. The fixed plate 43 is provided on the outer side of the movable rod 41 located inside the housing 42. A spring 44 is provided between the fixed plate 43 and the top of the housing 42.

[0041] The locking drive device 5 is symmetrically arranged on the first support platform 7 on both sides of the moving track of the skid 1, and is located below the locking mechanism 4. The locking drive device 5 includes its first cylinder 51 and top plate 52. The first cylinder 51 is arranged on the first support platform 7, and the top plate 52 is fixed on the telescopic rod of the first cylinder 51.

[0042] like Figure 9-10 As shown, the telescopic drive mechanism 6 is symmetrically arranged on the second support platform 8 on both sides of the moving track of the skid 1, and the telescopic drive mechanism 6 corresponds to each telescopic step 2. The telescopic drive mechanism 6 includes a second cylinder 61, a trolley 62, a pusher head 64 and a track 66. The second cylinder 61 and the track 66 are arranged on the second support platform 8. The telescopic rod of the second cylinder 61 is connected to the trolley 62. The trolley 62 moves in the track 66. A rotatable pusher head 64 is provided on one side of the trolley 62 for pushing the telescopic step 2 to move.

[0043] Furthermore, in order to prevent the pusher head 64 from blocking the movement space of the telescopic platform 2 when it is not in operation, the skid body 1 is provided with a stop bar 63 for limiting the rotation angle of the pusher head 64.

[0044] Furthermore, in order to facilitate the accurate movement of the telescopic platform 2 by the pusher head 64, one end of the pusher head 64 is rotatably connected to the trolley 62 via a pin 65, and the pusher head 64 has a V-shaped structure.

[0045] like Figure 11-12 When the telescopic platform 2 needs to extend, the skid 1 moves to the position above the locking drive device 5. The first cylinder 51 drives the top plate 52 to lift the movable rod 41. At this time, the locking pin 46 is lifted from the insertion holes 23 on both sides of the telescopic platform 2. The telescopic platform 2 is in an active state. Then, the second cylinder 61 in the telescopic drive mechanism 6 on one side pushes the trolley 62 to move. At this time, the push head 64 gradually disengages from the stop bar 63, making one end of it stand up. Then, under the push of the second cylinder 61, the positioning plate 22 is pushed to start moving until the platform 21 is extended to the position. The second cylinder 61 retracts, the push head 64 touches the stop bar 63 and resets, and then the first cylinder 51 retracts. Under the action of the spring 44, the movable rod 41 falls down, and the locking pin 46 falls into the insertion hole 23 on the positioning plate 22 to lock the position of the telescopic platform 2, completing the complete extension action of the telescopic platform 2.

[0046] When the telescopic platform 2 retracts, the skid 1 moves to the telescopic drive mechanism 6 at the other end. The arrangement of its second cylinder 61 is opposite to that of the second cylinder 61 that pushes the telescopic platform 2 to extend. For example, at the entrance, the two second cylinders 61 of the telescopic drive mechanism 6 are arranged on the right to control the extension of the telescopic platform 2. When it moves to the exit position, the two second cylinders 61 of the telescopic drive mechanism 6 are arranged on the left to push the telescopic platform 2 to reset.

[0047] A method for producing different vehicle models using telescopic skids includes:

[0048] like Figure 13 As shown, when producing large-scale vehicles, the telescopic steps 2 at both ends of the skid 1 are equipped with a telescopic drive mechanism 6 and a locking drive device 5 at the transition position at the entrance of the manual operation station, so that the telescopic steps 2 can extend. The telescopic drive mechanism 6 and the locking drive device 5 are equipped at the exit of the manual operation station, so that the telescopic steps 2 can retract. The length of the skid does not need to be set according to the length of the largest vehicle model, which can effectively save equipment layout space, increase storage capacity, and improve production efficiency.

[0049] like Figure 14 As shown, when producing small vehicles, the telescopic steps 2 at both ends of the skid 1 are kept in the retracted state, and all telescopic steps 2 in the storage area are kept in the retracted state to meet the standing requirements of personnel in manual operation positions.
