Description

Technical Field

[0001] This utility model relates to the field of automotive frame clamping technology, specifically to an electro-permanent magnet tray assembly line clamp. Background Technology

[0002] With the booming development of China's automobile industry, the variety of car brands and models is increasing, and the specifications of the corresponding seat frames are also becoming more diverse. The inner dimensions of the bottom slide rails and the positions of the positioning holes differ between different car models, posing challenges to the fixture design during the production and assembly process.

[0003] Traditional fixtures generally employ a hook-pin self-locking structure, whose positioning components are typically only compatible with specific vehicle models or a limited range of two to three models. Once the vehicle model is updated or the slide rail structure changes, the positioning blocks and other related components must be redesigned and remanufactured, resulting in repetitive tooling investment and impacting production response efficiency. Therefore, this solution provides a novel fixture structure that combines a centering mechanism with electro-permanent magnet technology, effectively addressing the aforementioned problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, an electro-permanent magnet pallet assembly line fixture is provided. This technical solution solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An electro-permanent magnet pallet assembly line fixture includes a standard pallet and a load-bearing component, a constraint component, and a clamping component mounted on the standard pallet. The standard pallet includes a pallet base, with a mounting plate fixedly installed on the top of the pallet base. The load-bearing component includes a sub-plate fixedly mounted on the mounting plate. Sliding clamping components are provided on both sides of the sub-plate. The clamping components include sliding plates slidably mounted on the sub-plate. Guide section one and guide section two are respectively provided between the two sides of the sub-plate and the two sliding plates. A constraint component is provided at the middle of the rear end of the sub-plate. The constraint component is used to constrain the two sliding plates to slide synchronously.

[0006] Preferably, two sets of slide rails are fixedly installed on both sides of the sub-plate, and sliding blocks are slidably installed on each set of slide rails. The lower end of the sliding plate on the same side is fixedly connected to the sliding block.

[0007] Preferably, the guide part one includes a spring force block one fixedly installed on both sides of the front end of the sub-plate, and two sets of spring force blocks two fixedly installed on the sliding plates on both sides respectively. A guide post one is fixedly installed on the spring force block one, one side of the guide post one is slidably connected to the spring force block two, and a spring one sleeved on the guide post one is fixedly connected between the spring force block one and the spring force block two.

[0008] Preferably, the guide part 2 includes spring force-receiving blocks 3 fixedly installed on both sides of the rear end of the sub-plate, and guide posts 2 fixedly installed on the spring force-receiving blocks 3. One end of the guide posts 2 is slidably connected to the sliding plate, and a spring 2 sleeved on the guide posts 2 is fixedly connected between the spring force-receiving blocks 3 and the sliding plate.

[0009] Preferably, the constraint assembly includes a central positioning block fixedly mounted on the sub-plate, a hinge block rotatably mounted on the central positioning block, hinge holes through both sides of the hinge block, hinge pins slidably connected inside the hinge holes on both sides, and the two sides of the hinge block are respectively fixedly connected to drive plate one and drive plate two through the hinge pins on both sides, and drive plate one and drive plate two are respectively fixedly connected to the lower ends of the sliding plates on both sides.

[0010] Preferably, the clamping assembly further includes a floating electromagnet fixedly mounted on the sliding plate. Two sets of positioning block bases are fixedly mounted on the sliding plate on both sides of the floating electromagnet. Guide positioning blocks are fixedly connected to the positioning block bases. The top of the guide positioning blocks is inclined. A hook-type positioning pin is fixedly mounted on the sliding plate on the front side of the floating electromagnet.

[0011] Compared with the prior art, the present invention proposes an electro-permanent magnet tray assembly line fixture, which has the following beneficial effects: This invention includes a constraint component and a clamping component. When the seat frame is placed on the clamp, the inner side of its bottom slide rail contacts the inclined surfaces of the guide positioning blocks on both sides, generating a lateral compressive force during the insertion process. This force pushes the guide positioning blocks, which in turn drive the sliding plates to move along the slide rail via the positioning block base. Under the action of the constraint component, the movement of the sliding plates on both sides remains synchronized: the outward displacement of one sliding plate is transmitted to the other side through the drive plate-hinge block mechanism, forcing the other sliding plate to move equidistantly and in the opposite direction, thereby realizing the system's automatic centering function. During this process, the floating electromagnet and the hook-type positioning pin are adjusted to the accurate coordinates corresponding to the preset position of the frame.

[0012] In this invention, after alignment, the floating electromagnet is energized to generate a strong attraction force, which securely attaches the skeleton to the clamp via the bottom of the slide rail. The floating electromagnet has a slight adaptive floating capability, ensuring full contact with the bottom surface of the skeleton and improving clamping stability. During clamping, springs one and two located on the front and rear sides of the sliding plate in the bearing component are continuously under pressure, storing elastic potential energy. When the skeleton is removed, the restoring force of the springs on both sides quickly pushes the sliding plate inward to reset, restoring the entire mechanism to its initial position, thereby enabling continuous operation preparation of the clamp.

[0015] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0016] Reference Figure 1-6 As shown, the electro-permanent magnet pallet assembly line fixture includes a standard pallet 1 and a load-bearing component 2, a constraint component 3, and a clamping component 4 disposed on the standard pallet 1. The standard pallet 1 includes a pallet base 101, and a mounting plate 102 is fixedly installed on the top of the pallet base 101. The load-bearing component 2 includes a sub-plate 201 fixedly installed on the mounting plate 102. Sliding clamping components 4 are provided on both sides of the sub-plate 201. The clamping component 4 includes a sliding plate 401 slidably installed on the sub-plate 201. A guide part one and a guide part two are respectively provided between the two sides of the sub-plate 201 and the two sliding plates 401. A constraint component 3 is provided at the middle of the rear end of the sub-plate 201. The constraint component 3 is used to constrain the two sliding plates 401 to slide synchronously.

[0017] Furthermore: the standard pallet 1 is a Yanfeng standard pallet, which effectively provides a rigid foundation for the fixture and improves the ability to quickly connect using existing standard pallets, ensuring the universality and portability of the fixture; during the clamping process, the sliding plate 401 of the clamping component 4 can slide on the sub-plate 201, and through the guide part 1 and guide part 2 arranged on both sides and the constraint component 3 located in the middle of the rear end of the sub-plate 201, the movement of the sliding plates 401 on both sides is precisely guided and synchronously controlled.

[0018] Reference Figure 3 and Figure 5 As shown, specifically in this embodiment, two sets of slide rails 202 are fixedly installed on both sides of the sub-plate 201, and sliding blocks 203 are slidably installed on each of the multiple sets of slide rails 202. The lower end of the sliding plate 401 on the same side is fixedly connected to the sliding block 203.

[0019] Furthermore, the cooperation of multiple sets of slide rails 202 and sliding blocks 203 provides high-precision, low-friction and stable linear motion guidance for the sliding plate 401, ensuring the reliability and durability of the clamping assembly 4 in repetitive actions.

[0020] Reference Figure 3 and Figure 5 As shown, specifically in this embodiment, the guide part one includes spring force blocks one 204 fixedly installed on both sides of the front end of the sub-plate 201, and two sets of spring force blocks two 206 fixedly installed on the sliding plates 401 on both sides respectively. A guide post one 205 is fixedly installed on the spring force block one 204. One side of the guide post one 205 is slidably connected to the spring force block two 206, and a spring one 207 sleeved on the guide post one 205 is fixedly connected between the spring force block one 204 and the spring force block two 206.

[0021] Furthermore, the guide post 205 ensures that the sliding plate 401 does not deflect during movement, thus improving the movement accuracy. The spring 207 moves and accumulates energy under the pressure of external force on the sliding plate 401. When the external force disappears, its restoring force can drive the sliding plate 401 to return to the initial position accurately and quickly, realizing the automatic reset of the fixture and providing a key role for subsequent continuous work.

[0022] Reference Figure 3 and Figure 5 As shown, specifically in this embodiment, the guide part two includes spring force-receiving blocks three 208 fixedly installed on both sides of the rear end of the sub-plate 201. A guide post two 209 is fixedly installed on the spring force-receiving blocks three 208. One end of the guide post two 209 is slidably connected to the sliding plate 401, and a spring two 2010 sleeved on the guide post two 209 is fixedly connected between the spring force-receiving blocks three 208 and the sliding plate 401.

[0023] Furthermore, the working principle and the final effect achieved are the same as those of the guide part one, and will not be repeated here. By working together with the guide part one, a stable elastic support system is formed at both ends, which further ensures the smoothness of the movement process of the sliding plate 401 and the accuracy of its reset.

[0024] Reference Figure 4 As shown, specifically in this embodiment, the constraint component 3 includes a central positioning block 301 fixedly installed on the sub-plate 201. A hinge block 302 is rotatably installed on the central positioning block 301. Hinge holes 303 are provided through both sides of the hinge block 302. Hinge pins 304 are slidably connected inside the hinge holes 303 on both sides. The two sides of the hinge block 302 are fixedly connected to the first drive plate 305 and the second drive plate 306 respectively through the hinge pins 304 on both sides. The first drive plate 305 and the second drive plate 306 are fixedly connected to the lower ends of the sliding plates 401 on both sides respectively.

[0025] Furthermore, the automatic centering effect of the fixture is achieved through the transmission structure of the constraint component 3: when one side sliding plate 401 is moved by external force, the hinge block 302 is pushed to rotate around the central positioning block 301 by the drive plate 305 or drive plate 306 and hinge pin 304, thereby forcing the sliding plate 401 fixed at its top to move synchronously and equidistantly in the opposite direction through the drive plate 306 or drive plate 305 on the other side; this structure ensures that the fixture can automatically adapt to workpieces of different sizes and keep them in the center position, achieving efficient flexible compatibility.

[0026] Reference Figure 6 As shown, specifically, in this embodiment, the clamping assembly 4 further includes a floating electromagnet 402 fixedly installed on the sliding plate 401. Two sets of positioning block bases 403 are fixedly installed on the sliding plate 401 on both sides of the floating electromagnet 402. A guide positioning block 404 is fixedly connected to the positioning block base 403. The top of the guide positioning block 404 is inclined, and a hook-type positioning pin 405 fixedly installed on the sliding plate 401 is provided on the front side of the floating electromagnet 402.

[0027] Furthermore: When the seat frame is placed on the clamp, the inner side of its bottom slide rail contacts the inclined surfaces of the two guide positioning blocks 404, generating lateral compressive force during the insertion process. This force pushes the guide positioning blocks 404, which in turn drives the sliding plates 401 to move along the slide rail 202 through the positioning block base 403. Under the action of the constraint component 3, the movement of the two sliding plates 401 remains synchronized: when one sliding plate 401 moves outward, it is transmitted to the other side through the drive plate and hinge block mechanism, forcing the other sliding plate 401 to move equidistantly and in the opposite direction, thereby realizing the automatic centering function of the system; during this process, the floating electromagnet 402 and the hook positioning pin 405 are adjusted to the accurate coordinates corresponding to the preset position of the frame; and inserted into the workpiece positioning hole to achieve precise positioning and eliminate errors. As the final execution unit, the floating electromagnet 402 generates a strong adsorption force after being energized to firmly fix the workpiece. Its "floating" design allows it to make minor adaptive adjustments to ensure complete contact with the bottom surface of the workpiece, greatly improving the reliability and stability of the clamping.

[0028] The working principle of this utility model is as follows: when the seat frame is placed on the fixture, the inner side of the slide rail at its bottom will contact the inclined surface of the guide positioning block 404 installed on the two side slide plates 401; under the action of the workpiece, the inclined surface is squeezed, and then transmitted to the slide plate 401 through the positioning block base 403, pushing the slide plate 401 to slide on the slide rail 202 with the help of the sliding block 203. Under the forced movement of the constraint component 3, the sliding plate 401 moves synchronously and equidistantly in the opposite direction, enabling the fixture to automatically adjust regardless of the workpiece size, ensuring the workpiece is always moved to the accurate centered position, achieving self-adaptive centering. Simultaneously, as the sliding plate 401 completes its centering movement, the hook-type positioning pin 405, fixedly installed on it, is precisely inserted into the corresponding positioning hole at the bottom of the seat frame, achieving precise workpiece positioning. Subsequently, the floating electromagnet 402 is energized. The powerful permanent magnet force generated after energization firmly attracts the workpiece to the surface of the clamp through the bottom of the slide rail of the frame. The "floating" design of the floating electromagnet 402 itself allows it to make minute adaptive adjustments, ensuring that even if there are slight unevennesses on the bottom surface of the workpiece, a tight fit can be achieved over the entire area, thus completing a flexible and reliable final clamping.

[0029] Meanwhile, during the entire clamping process, the spring 207 at the front end and the spring 2010 at the rear end of the clamp are under pressure and store elastic potential energy. When production is completed, the floating electromagnet 402 is de-energized. At this time, the potential energy stored in the spring 207 and the spring 2010 is released instantly. Its restoring force pushes the sliding plates 401 on both sides to return to their original positions smoothly and quickly along the guide post 205 and the guide post 209. This drives all positioning and clamping elements to accurately return to their initial positions to welcome the next workpiece, thus achieving efficient continuous cycle operation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
