Addressing the problem that most automotive parts assembly is currently done manually, resulting in slow, time-consuming, and labor-intensive operations with insufficient assembly stability, the proposed solution includes an operating table with four symmetrically arranged support rods fixedly mounted on its top. The tops of the four support rods are fixedly mounted with the same top plate. However, this solution still suffers from the following drawback: it lacks a positioning mechanism, leading to misalignment during parts assembly and resulting in significant errors in the assembled parts. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a modular assembly and positioning device for parts, mainly to solve the problem of the lack of a positioning mechanism, which causes misalignment during parts assembly, resulting in large errors in the assembled parts.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A modular assembly and positioning device for parts includes an L-shaped plate. A first groove is formed on one side of the L-shaped plate, and a carriage is slidably connected within the first groove. A power mechanism for moving the carriage is provided on the top of the L-shaped plate. A first support plate is placed on the upper surface of the L-shaped plate, and multiple fixing blocks are fixedly connected to the upper surface of the first support plate. A second support plate is fixedly connected to the top of the multiple fixing blocks. Two second grooves and two third grooves are formed on the upper surface of the second support plate. Two second clamping blocks are slidably connected to each of the two second grooves, and first clamping blocks are slidably connected within each of the two third grooves. The L-shaped plate has two sliding openings on its upper surface, and a sliding plate is slidably connected to each of the two sliding openings. A fixing frame is fixedly connected to both sides of the sliding plate. A first pull rope is fixedly connected to one side of the first clamping block, and one end of the first pull rope passes through another first clamping block and extends out to a second support plate, which is threadedly connected to the fixing frame through a fixing ring. A second pull rope is fixedly connected to one side of the second clamping block, and one end of the second pull rope passes through another second clamping block and extends out to a second support plate, which is threadedly connected to the sliding plate through a fixing ring. A limiting mechanism for limiting the first support plate is provided on one side of the sliding plate.

[0009] Furthermore, the power mechanism includes a fixed plate, which is fixed to an L-shaped plate. A cylinder is fixedly connected to the top of the fixed plate, and one end of the cylinder's pneumatic rod passes through the fixed plate and is fixed to the slide.

[0010] Based on the aforementioned scheme, the limiting mechanism includes a second groove, which is opened on one side of the slide plate. A second wedge block is slidably connected in the second groove, and a first compression spring is fixedly connected to the top of the second wedge block. A clearance groove is opened at the top of the second groove, and the first compression spring is fixed to the clearance groove. Slots are opened on both sides of the first support plate.

[0011] As a further embodiment of the present invention, the inner walls of the carriage are provided with first grooves on multiple sides, a first wedge block is slidably connected in the first groove, a second compression spring is fixedly connected to one side of the first wedge block, and the second compression spring is fixed to the first groove.

[0012] Furthermore, a guide rod is fixedly connected inside the first groove, and the guide rod is slidably connected to the first wedge block.

[0013] Based on the aforementioned scheme, two fixing ribs are fixedly connected to the outer side of the cylinder, and the fixing ribs are fixed to the fixing plate.

[0014] As a further embodiment of the present invention, both the first clamping block and the second clamping block are provided with multiple anti-slip patterns on one side, and the anti-slip patterns are evenly distributed.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a modular assembly and positioning device for parts, which has the following advantages:

[0018] 1. By using the first clamping block, the second clamping block, the first pull rope, and the second pull rope in combination, the part is placed on the second support plate. The cylinder pushes the slide to move downward, the slide will push the slide plate to move downward, the slide plate will drive the fixed frame to move downward, and the slide plate and the fixed frame will pull the first clamping block and the second clamping block to move through the first pull rope and the second pull rope, so that the first clamping block and the second clamping block clamp and position the part, avoid the part from being displaced, and prevent the part from being assembled with errors, thereby improving the accuracy of the part assembly.

[0019] 2. By using the first and second pull ropes together, since the first and second pull ropes are threadedly connected to the slide plate and the fixed frame through the fixed ring, the first and second pull ropes can be detached from the slide plate and the fixed frame, so that a second support plate with a larger area can be replaced to place the parts and clamp the parts of different sizes, thereby improving the use effect of the positioning equipment.

[0020] 3. By setting the limiting mechanism, the second wedge block will move downward as the slide moves downward. The second wedge block will enter the slot. At this time, the slide continues to move downward, which will cause the second wedge block to move along the second groove and squeeze the first compression spring. When the second wedge block moves to the top of the second groove, it will limit the first support plate, thereby preventing the first support plate from moving and causing the parts to shift, and further improving the accuracy of parts assembly.

[0021] 4. By setting anti-slip texture, when using the first clamping block and the second clamping block to clamp and position the part, the anti-slip texture can increase the friction between the first clamping block, the second clamping block and the part, making the clamping of the part by the first clamping block and the second clamping block more stable, and improving the stability of clamping and positioning the part.

[0030] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Reference Figures 1-7A modular assembly and positioning device for parts includes an L-shaped plate 4. A first groove 11 is formed on one side of the L-shaped plate 4, and a carriage 10 is slidably connected within the first groove 11. A power mechanism for moving the carriage 10 is provided on the top of the L-shaped plate 4. A first support plate 17 is placed on the upper surface of the L-shaped plate 4. Multiple fixing blocks 16 are welded to the upper surface of the first support plate 17. A second support plate 18 is bolted to the top of the multiple fixing blocks 16. Two second grooves 20 and two third grooves 32 are formed on the upper surface of the second support plate 18. Two second sliding grooves 20 are slidably connected to second clamping blocks 33, and two third sliding grooves 32 are slidably connected to first clamping blocks 19. Two sliding openings 15 are formed on the upper surface of the L-shaped plate 4, and sliding plates 5 are slidably connected to both openings 15. The slide frame 10 contacts the sliding plate 5. Fixing frames 9 are welded to both sides of the sliding plate 5. A first pull rope 23 is adhered to one side of the first clamping block 19, and one end of the first pull rope 23 passes through the other first clamping block 19 and extends out to a second support plate 18, which is threadedly connected to the fixing frame 9 via a fixing ring. The second clamping blocks 33... A second pull rope 35 is attached to one side of the first support plate 17, and one end of the second pull rope 35 passes through another second clamping block 33 and extends out to the second support plate 18, which is threadedly connected to the slide plate 5 via a fixing ring. A limiting mechanism is provided on one side of the slide plate 5 to limit the first support plate 17. When the part is placed on the second support plate 18, the power mechanism is started. The power mechanism pushes the slide 10 to move downward along the first slide groove 11. During the movement, the slide 10 will contact the slide plate 5. At this time, the slide 10 will push the slide plate 5 downward, and the slide plate 5 will drive the fixing frame 9. As the slide plate 5 and the fixing frame 9 move downwards, when they are below the height of the second support plate 18, the slide plate 5 will pull the first clamping block 19 along the third slide groove 32 via the first pull rope 23, and the fixing frame 9 will pull the second clamping block 33 along the second slide groove 20 via the second pull rope 35. When the slide plate 5 moves downwards to the limit mechanism and limits the first support plate 17, the first clamping block 19 and the second clamping block 33 will clamp and position the parts to prevent displacement of the parts and thus prevent errors in the assembly of the parts, thereby improving the accuracy of the assembly of the parts.

[0032] In particular, the power mechanism of this invention includes a fixed plate 3, which is fixed to an L-shaped plate 4. A cylinder 1 is bolted to the top of the fixed plate 3, and one end of the pneumatic rod of the cylinder 1 passes through the fixed plate 3 and is fixed to the slide 10. The limiting mechanism includes a second groove 30, which is opened on one side of the slide plate 5. A second wedge block 28 is slidably connected in the second groove 30. A first compression spring 29 is welded to the top of the second wedge block 28. A clearance groove 22 is opened at the top of the second groove 30, and the first compression spring 29 is fixed to the clearance groove 22. Slots 36 are opened on both sides of the first support plate 17, and the second wedge block 28 is engaged with the slots 36. When the slide plate 5 moves downward, it will drive the second wedge block 28. When the second wedge block 28 moves and engages with the slot 36, the slide plate 5 continues to move downwards. This causes the second wedge block 28 to move along the second groove 30 and compress the first compression spring 29. Once the second wedge block 28 reaches the top of the second groove 30, the slide plate 5 will no longer move downwards, and the second wedge block 28 will limit the movement of the first support plate 17. The slide 10 has multiple inner walls with first grooves 14. A first wedge block 12 is slidably connected within the first groove 14. A second compression spring 31 is welded to one side of the first wedge block 12 and is fixed to the first groove 14. When the connector is placed on the first wedge block 12 on the slide 10 and pressed, the connector will... The first wedge block 12 is pressed into the first groove 14 and compresses the second compression spring 31, pressing the connector into contact with the part. At this time, the first wedge block 12 will provide auxiliary clamping and positioning for the connector, and then the connector and the part can be connected. A guide rod 13 is fixed in the first groove 14 by bolts, and the guide rod 13 is slidably connected to the first wedge block 12. The guide rod 13 guides the movement of the first wedge block 12. Two fixing ribs 2 are fixed to the outside of the cylinder 1 by bolts, and the fixing ribs 2 are fixed to the fixing plate 3. The fixing ribs 2 can enhance the stability of the fixation between the cylinder 1 and the fixing plate 3. Multiple anti-slip textures 21 are provided on one side of the first clamping block 19 and the second clamping block 33. The anti-slip texture 21 is evenly distributed. The anti-slip texture 21 can increase the friction between the first clamping block 19, the second clamping block 33 and the part, making the clamping of the part by the first clamping block 19 and the second clamping block 33 more stable and improving the stability of the clamping and positioning of the part. A first spring 24 is welded to one side of the first clamping block 19 and the first spring 24 is fixed to the third slide groove 32. A second spring 34 is welded to one side of the second clamping block 33 and the second spring 34 is fixed to the second slide groove 20. Handles 8 are fixed to both sides of the L-shaped plate 4 by bolts. Multiple feet 6 are fixed to the bottom of the L-shaped plate 4 by bolts. Anti-slip pads 7 are glued to the bottom of the multiple feet 6. The anti-slip pads 7 can increase the friction between the feet 6 and the ground.

[0033] The working principle of this embodiment is as follows: In use, the part is placed on the second support plate 18, and cylinder 1 is activated. Cylinder 1 extends, pushing the slide 10 downwards along the first slide groove 11. During this movement, the slide 10 contacts the slide plate 5, pushing it downwards. The slide plate 5 then moves the fixing frame 9 downwards. When the slide plate 5 and fixing frame 9 move below the height of the second support plate 18, the slide plate 5 pulls the first clamping block 19 along the third slide groove 32 via the first pull rope 23, compressing the first spring 24. The fixing frame 9 pulls the second clamping block 33 along the second slide groove 20 via the second pull rope 35, compressing the second spring 34. During this downward movement, the slide plate 5 moves the second wedge block 28. When the second wedge block 28 engages with the slot 36, the slide plate 5 continues to move downwards. As the slide continues to move downwards, the second wedge block 28 will move along the second groove 30 and compress the first compression spring 29. When the second wedge block 28 moves to the top of the second groove 30, the slide plate 5 will no longer move downwards, and the second wedge block 28 will limit the first support plate 17. At the same time, the first clamping block 19 and the second clamping block 33 will clamp and position the part to prevent the part from shifting and causing errors in the part assembly, thus improving the accuracy of the part assembly. Then, the connector is placed on the first wedge block 12 on the slide 10. Pressing the connector will cause the connector to squeeze the first wedge block 12 into the first groove 14 and compress the second compression spring 31. After the connector is pressed into contact with the part, the first wedge block 12 will provide auxiliary clamping and positioning for the connector. Then, the connector and the part can be connected.
