Description

Technical Field

[0001] This utility model relates to the field of skid switching technology, and in particular to a switching mechanism for skids applicable to multiple vehicle models. Background Technology

[0002] A skid is a widely used carrier and conveyor in automated production lines. It is typically composed of a metal frame combined with guiding, positioning, and supporting functional components. It is mainly used to carry workpieces and smoothly transfer them on the production line via conveying equipment. It is a switching mechanism suitable for skids of multiple vehicle models. It is a flexible adjustment device integrated into automated production lines. Its core function is to quickly adapt to skids corresponding to different vehicle models through the synergistic action of mechanical structure, sensor control, or power drive. It realizes automatic switching or manual adjustment of key parameters such as skid size, positioning reference, and support point to meet the compatibility requirements of skids when multiple vehicle models are produced on the same line.

[0003] Since different vehicle models need to share the same skid, in order to achieve skid switching between different vehicle models and reduce skid and personnel investment, quick switching is required. However, when using existing skids, it is inconvenient to quickly disassemble and assemble the skids with the conveyor structure according to different vehicle models, which limits the efficiency of automated production.

[0004] Therefore, a switching mechanism suitable for skids of multiple vehicle models is needed to solve the above problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the above-mentioned problems with the switching mechanism for skids applicable to multiple vehicle models, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide a switching mechanism for skids applicable to multiple vehicle models, which solves the problem that "since different vehicle models need to share skids, in order to achieve skid switching between different vehicle models and reduce skid and personnel investment, quick switching is required. However, existing skids are inconvenient to quickly disassemble and assemble with the conveyor structure according to different vehicle models, which limits the efficiency of automated production."

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a switching mechanism for skids suitable for multiple vehicle models, comprising:

[0009] The track has a conveyor wheel slidably mounted on its top surface, a conveyor frame is mounted above the conveyor wheel, and a skid is engaged above the conveyor frame.

[0010] A disassembly and assembly unit is placed above the track. The disassembly and assembly unit includes a locking block and a locking slot, which are used to quickly disassemble and assemble the skid frame and the conveyor frame, so as to switch the skid frame according to different vehicle models.

[0011] An adjustment unit is located above the disassembly and assembly unit. The adjustment unit includes opposing threaded rods, a first magnetic ring, a second magnetic ring, and a support rod. It is used to adjust the spacing between the support rods to accommodate frames with different wheelbases. Under the restriction of magnetic repulsion, the support rods can be buffered and adaptively aligned with the frame mounting holes to avoid forced alignment and insertion of the support rods and mounting holes.

[0012] As a preferred embodiment of the multi-vehicle skid switching mechanism of this utility model, the disassembly and assembly unit includes a first telescopic rod fixedly installed inside the conveyor frame. A push plate is fixedly installed at the end of the first telescopic rod. A slide rod is fixedly installed on the side wall of the push plate. A fixing block is fixedly installed on the top surface of the conveyor frame. A limit rod is slidably arranged inside the fixing block. A locking block is fixedly installed at the end of the limit rod. An inclined frame is fixedly installed on the side of the locking block near the limit rod. A locking groove is engaged on the outer wall of the locking block.

[0013] As a preferred embodiment of the switching mechanism for multi-vehicle skids described in this utility model, the skid frame is fixedly mounted with a mounting plate at its bottom end, a reinforcing block is fixedly mounted on the top surface of the mounting plate, a positioning hole is provided inside the mounting plate, and a positioning rod is inserted into the positioning hole.

[0014] As a preferred embodiment of the multi-vehicle skid switching mechanism described in this utility model, the inclined frame is inclined, and the outer wall of the slide rod is slidably disposed with the inside of the inclined frame. Under the restriction of the inclined frame, the downward moving slide rod can squeeze the inclined frame, causing the inclined frame to drive the locking block to move away from the locking slot and no longer engage with the locking slot.

[0015] As a preferred embodiment of the switching mechanism for multi-vehicle skids described in this utility model, the end of the positioning rod is fixedly installed on the top surface of the conveyor frame. The end of the positioning rod is frustum-shaped and sleeved with the positioning hole. Under its constraint, the skid frame and the conveyor frame can be positioned and installed so that the locking block and the locking slot can be accurately engaged.

[0016] As a preferred embodiment of the switching mechanism for multi-vehicle skids described in this utility model, the adjustment unit includes an upright plate fixedly installed at the bottom of the skid frame. A counter-threaded rod is rotatably connected inside the upright plate. A sleeve is fitted on the outer wall of the counter-threaded rod. A slider is fixedly installed at the end of the sleeve. A second telescopic rod is fixedly installed on the top surface of the slider.

[0017] As a preferred embodiment of the switching mechanism for multi-vehicle skids described in this utility model, wherein: a sleeve is fixedly installed at the end of the second telescopic rod, a first magnetic ring is fixedly installed on the inner wall of the sleeve, a second magnetic ring is slidably arranged inside the sleeve, and a support rod is fixedly installed on the side of the second magnetic ring away from the first magnetic ring.

[0018] As a preferred embodiment of the multi-model skid switching mechanism described in this utility model, the first magnetic ring and the second magnetic ring are magnetically repulsive, and the outer wall of the support rod is slidably disposed with the inside of the sleeve. Under the restriction of magnetic repulsion, the frame and the support rod are buffered and aligned, so that it has a buffering and error correction positioning function.

[0019] The beneficial effects of this utility model are as follows: When conveying different vehicle models, the first telescopic rod is activated to pull the push plate and slide rod downward. Because the slide rod slides and engages with the inclined frame, it will squeeze the inclined frame and drive the locking block to slide out of the slot. The limit rod assists the locking block to slide stably. At this time, the locking block disengages from the slot of the skid frame mounting plate, and the skid frame can be switched. The mounting plate of another type of skid frame is aligned and inserted with the positioning rod. Then, the first telescopic rod is activated to push the slide rod upward, so that the inclined frame drives the locking block to engage with the slot to complete the installation. This realizes the quick disassembly and switching of the skid frame and the conveyor frame, and improves the efficiency of automated production.

[0020] When the vehicle models are the same, rotating the opposing threaded rod and using the slider limiter can adjust the distance between the sleeve and the support rod; activating the second telescopic rod can adjust the height of the support rod. If the frame mounting hole and the support rod are misaligned, the support rod will be squeezed and will cause the second magnetic ring to slide into the sleeve. After the frame is finely adjusted and aligned, the repulsive force of the first and second magnetic rings will be used to push the support rod back to its original position, which plays a role in buffering and correcting the positioning, and avoids misalignment.

[0033] Example 1

[0034] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention, which provides a switching mechanism for skids applicable to multiple vehicle models, comprising:

[0035] Track 100, with a conveyor wheel 101 slidably mounted on the top surface of track 100, a conveyor frame 102 mounted above the conveyor wheel 101, and a skid frame 103 snapped onto the top of the conveyor frame 102;

[0036] The disassembly and assembly unit 200 is placed above the track 100. The disassembly and assembly unit 200 includes a locking block 206 and a locking slot 208, which are used to quickly disassemble and assemble the skid frame 103 and the conveyor frame 102 so as to switch the skid frame 103 according to different vehicle models.

[0037] The adjustment unit 300 is located above the disassembly and assembly unit 200. The adjustment unit 300 includes opposing threaded rods 302, a first magnetic ring 307, a second magnetic ring 308, and a support rod 309. It is used to adjust the spacing of the support rods 309 to adapt to frames with different wheelbases. Under the restriction of magnetic repulsion, the support rods 309 can be buffered and adaptively aligned with the frame mounting holes to avoid the support rods 309 being forcibly aligned and inserted with the mounting holes.

[0038] In use, the skid frame 103 can support the vehicle frame. With the cooperation of the track 100, the conveyor wheel 101 and the conveyor frame 102, the skid frame 103 can be conveyed. With the restriction of the adjustment unit 300, the position of the support rod 309 can be adjusted according to the wheelbase of the vehicle frame. With the cooperation of magnetic repulsion, the support rod 309 can be buffered and aligned with the vehicle frame placement hole. With the restriction of the disassembly and assembly unit 200, the skid frame 103 and the conveyor frame 102 can be quickly switched to transport different vehicle models.

[0039] Example 2

[0040] Reference Figure 3 and Figure 4 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiment, as follows:

[0041] The disassembly and assembly unit 200 includes a first telescopic rod 201 fixedly installed inside the conveyor frame 102. A push plate 202 is fixedly installed at the end of the first telescopic rod 201. A slide rod 203 is fixedly installed on the side wall of the push plate 202. A fixing block 204 is fixedly installed on the top surface of the conveyor frame 102. A limit rod 205 is slidably arranged inside the fixing block 204. A locking block 206 is fixedly installed at the end of the limit rod 205. A slanted frame 207 is fixedly installed on the side of the locking block 206 near the limit rod 205. A locking groove 208 is engaged on the outer wall of the locking block 206. An installation plate 209 is fixedly installed at the bottom of the skid frame 103. A reinforcing block 210 is fixedly installed on the top surface of the installation plate 209. A positioning hole 211 is opened inside the installation plate 209. A positioning rod 212 is inserted into the positioning hole 211.

[0042] The inclined frame 207 is inclined, and the outer wall of the slide rod 203 is slidably disposed with the inside of the inclined frame 207. Under the restriction of the inclined frame 207, the downward moving slide rod 203 can squeeze the inclined frame 207, causing the inclined frame 207 to drive the locking block 206 to move away from the locking groove 208 and no longer lock with the locking groove 208.

[0043] The end of the positioning rod 212 is fixedly installed on the top surface of the conveyor frame 102. The end of the positioning rod 212 is frustum-shaped and is fitted with the positioning hole 211. Under its constraint, the skid frame 103 and the conveyor frame 102 can be positioned and installed so that the locking block 206 and the locking groove 208 can be accurately engaged.

[0044] During use, when transporting different vehicle models, the skid frame 103 needs to be switched. At this time, the first telescopic rod 201 is activated, which pulls the push plate 202 downward. The push plate 202 drives the slide rod 203 to move downward. Because the outer wall of the slide rod 203 slides against the inside of the inclined frame 207, and the inclined frame 207 is inclined, under its constraint, the downward-moving slide rod 203 squeezes the inside of the inclined frame 207, causing the inclined frame 207 to drive the locking block 206 to slide outward towards the slot 208. The limiting rod 205, which is fixedly installed on the side of the locking block 206 near the inclined frame 207, slides inside the fixing block 204. Under its constraint, the locking block 206 can slide stably. At this time, the locking block 206 no longer exerts pressure on the inside of the slot 208. The mounting plate 209, which is fixedly installed at the bottom of the skid frame 103, has a slot 208 on its outer wall that engages with the skid frame 103. This allows the skid frame 103 to be switched. The mounting plate 209 fixedly installed at the bottom of the skid frame 103 of another model is aligned with the positioning rod 212, so that the positioning hole 211 inside the mounting plate 209 is inserted and positioned with the positioning rod 212. The first telescopic rod 201 is activated, which pushes the push plate 202 and the slide rod 203 upward, causing the inclined frame 207 to be squeezed, which drives the locking block 206 to engage with the slot 208. This allows the skid frame 103 to be installed with the conveyor frame 102. This structure allows for quick disassembly and switching between the skid frame 103 and the conveyor frame 102, improving the efficiency of automated production.

[0045] Example 3

[0046] Reference Figure 5 and Figure 6 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiments, as detailed below:

[0047] The adjustment unit 300 includes a vertical plate 301 fixedly installed at the bottom of the skid frame 103. A counter-threaded rod 302 is rotatably connected inside the vertical plate 301. A sleeve 303 is sleeved on the outer wall of the counter-threaded rod 302. A slider 304 is fixedly installed at the end of the sleeve 303. A second telescopic rod 305 is fixedly installed on the top surface of the slider 304. A sleeve 306 is fixedly installed at the end of the second telescopic rod 305. A first magnetic ring 307 is fixedly installed on the inner wall of the sleeve 306. A second magnetic ring 308 is slidably arranged inside the sleeve 306. A support rod 309 is fixedly installed on the side of the second magnetic ring 308 away from the first magnetic ring 307.

[0048] Among them, the first magnetic ring 307 and the second magnetic ring 308 are magnetically repulsive, and the outer wall of the support rod 309 is slidably disposed with the inside of the sleeve 306. Under the restriction of magnetic repulsion, the frame and the support rod 309 are buffered and aligned, so that it has a buffering and error correction positioning function.

[0049] When in use, for vehicles of the same type, the position of the support rod 309 needs to be adjusted according to its wheelbase. At this time, rotating the opposing threaded rod 302 causes the sleeve 303 on its outer wall to move due to the sliding arrangement between the outer wall of the slider 304 and the inside of the skid frame 103. This adjusts the spacing of the support rods 309. Activating the second telescopic rod 305 allows for adaptive adjustment of the height of the support rods 309. When the frame mounting hole and the support rod 309 are not precisely connected, the support rod 309 is compressed, causing the second magnetic ring 308 to slide into the sleeve 306. As the frame moves downward and is finely adjusted, the support rod 309 is aligned with the mounting hole. Under the magnetic repulsion between the second magnetic ring 308 and the first magnetic ring 307, the support rod 309 is pushed back to its original position. This buffering effect prevents misalignment between the frame and the support rod 309, providing a buffering and corrective positioning function.

[0050] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0051] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine task in design, manufacturing, and production without requiring extensive experimentation.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
