Abstract
Description
Technical Field
[0001] This utility model relates to the field of clamping technology, and in particular to a scratch-resistant sheet metal handling clamp. Background Technology
[0002] In industries such as construction and decoration, furniture manufacturing, cold chain packaging, and chemical equipment manufacturing, polyethylene (PE) sheets are widely used as a basic material due to their excellent corrosion resistance, wear resistance, and impact resistance. From the hygiene requirements of food-grade cold chain packaging to the corrosion protection of chemical storage tanks, and the wear-resistant applications in building decoration, the surface integrity of PE sheets directly affects their functionality and service life. However, because PE sheets are relatively soft and their surfaces are easily scratched and abraded, surface damage during handling not only affects appearance but may also impair their corrosion resistance and moisture resistance, leading to premature material failure. Especially in mass production and transportation scenarios, traditional handling methods cannot meet the dual requirements of surface protection and efficient handling of PE sheets, necessitating innovative fixtures to solve this problem.
[0003] There are two main types of clamps used for handling sheet metal: one is a manually adjustable clamp, which uses a screw or lever structure to manually adjust the spacing between the clamps and uses metal clamps to directly clamp the edges of the sheet metal, relying on friction to fix the sheet metal; the other is a pneumatic or hydraulically driven clamp, which uses cylinders or hydraulic cylinders to generate power to open and close the clamps.
[0004] However, existing sheet metal handling clamps generally suffer from inconvenient clamp spacing adjustment, insufficient surface protection, and difficulty in adapting to different specifications of polyethylene sheets. This leads to easy scratching and damage to the sheet surface during handling, affecting material performance and usability. Manual clamps rely on repeated manual adjustments, which are time-consuming and difficult to accurately match the thickness variations of polyethylene sheets. If too loose, the sheet may slip off; if too tight, it may leave indentations or even scratches on the sheet surface. While pneumatic and hydraulic clamps have rapid adjustment capabilities, their fixed clamps cannot adaptively fit the polyethylene sheet surface, and uneven contact between the gaskets and the sheet results in excessive local pressure, causing surface scratches or dents. Therefore, a scratch-resistant sheet metal handling clamp is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a scratch-resistant sheet material handling clamp, which aims to improve the problems of inconvenient clamp spacing adjustment, insufficient surface protection measures, and difficulty in adapting to polyethylene sheets of different specifications in the prior art, which makes it easy to scratch and damage the surface of the sheet material during handling.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A scratch-resistant sheet metal handling clamp includes a support plate, a handle fixedly connected to the top of the support plate, a motor fixedly connected to the top of the support plate, a gear fixedly connected to the output end of the motor, symmetrically positioned limit blocks fixedly connected to the bottom of the motor, a first slide rod and a second slide rod provided at the bottom of the support plate, both slide rods having a limiting groove inside, the two limiting blocks being slidably connected inside the two limiting grooves, racks fixedly connected to the inner walls of both slide rods, both racks meshing with the gear, and clamping components provided at the bottom of both slide rods.
[0008] The clamping assembly includes a clamping plate one and a clamping plate two, which are respectively disposed at the bottom of the slide rod one and the slide rod two. A rubber plate is fixedly connected to one side of each of the clamping plates one and two, and a connecting assembly is provided inside each of the clamping plates one and the rubber plate.
[0009] As a further description of the above technical solution:
[0010] The connecting assembly includes two hollow columns and pins. The two hollow columns are respectively disposed inside the first clamping plate and the second clamping plate. The bottom ends of the two pins are respectively fixedly connected to the top ends of the two hollow columns. The two pins are respectively slidably connected inside the first slide rod and the second slide rod.
[0011] As a further description of the above technical solution:
[0012] The hollow column is slidably connected to a sliding column, and a connecting column is fixedly connected to the top of the sliding column.
[0013] As a further description of the above technical solution:
[0014] A cone block is fixedly connected to the outer wall of the connecting column, and a connecting ring is fixedly connected to the outer wall of the sliding column.
[0015] As a further description of the above technical solution:
[0016] The pin has a sliding bead inside, and the cone block is in contact with the bead.
[0017] As a further description of the above technical solution:
[0018] A spring is fitted on the outer wall of the sliding column, and the two ends of the spring are fixedly connected to the hollow column and the connecting ring, respectively.
[0019] As a further description of the above technical solution:
[0020] A button is fixedly connected to the bottom of the sliding column, and the button is slidably connected inside the hollow column.
[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, the gear is driven by a motor to rotate, and the gear meshes with the rack on the inner wall of the slide rod. Under the guidance of the limiting structure, the slide rod slides in the opposite direction to realize the automatic adjustment of the clamping plate spacing. The rubber plate on one side of the clamping plate, with its flexible properties, fully fits the surface of the plate and provides cushioning protection. These structures work together to achieve the effect of quickly adjusting the clamping spacing according to the width of the plate and all-round anti-scratch handling. This solves the problems of inconvenient clamping plate spacing adjustment, insufficient surface protection measures, and difficulty in adapting to different specifications of polyethylene plates, which leads to easy scratching and damage to the surface of the plate during handling. This improves the practicality of the plate handling clamp.
[0023] 2. In this utility model, pressing the button compresses the spring, causing the cone block to disengage from the retaining bead. After inserting the pin, releasing the button resets the spring, pushing the sliding column to cause the cone block to press against the retaining bead, thus firmly locking the pin and achieving quick fixing or disassembly of the clamping plate. These structures work together to achieve convenient disassembly and quick replacement of the clamping plate, solving the problems of traditional clamping plates being difficult to disassemble, time-consuming and laborious to maintain, and unable to repair the protective function in a timely manner, thereby improving the flexibility of the plate handling clamp.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figures 1-3 This utility model provides an embodiment of a scratch-resistant plate handling clamp, including a support plate 1 as the basic structure of the entire clamp, the support plate 1 provides a stable support surface, a handle 3 is fixedly connected to the top of the support plate 1, the handle 3 facilitates manual handling or adjustment of the clamp position by the operator, a motor 2 is fixedly connected to the top of the support plate 1, a gear 4 is fixedly connected to the output end of the motor 2, and a front-to-back symmetrical limit block 5 is fixedly connected to the bottom of the motor 2, which can prevent excessive movement of the clamp during operation and ensure that the clamping plates 10 and 11 are kept within a predetermined range when clamped, a slide rod 1 6 and a slide rod 2 7 are provided at the bottom of the support plate 1, and a limit groove 9 is provided inside the slide rod 1 6 and the slide rod 2 7, respectively. The two limit blocks 5 are slidably connected inside the two limit grooves 9, and racks 8 are fixedly connected to the inner walls of the slide rod 1 6 and the slide rod 2 7, and the two racks 8 mesh with the gear 4. A clamping assembly is provided at the bottom of the slide rod 1 6 and the slide rod 2 7.
[0033] The clamping assembly includes clamping plate 10 and clamping plate 21. Clamping plate 10 and clamping plate 211 are respectively located at the bottom of slide bar 16 and slide bar 27. Clamping plate 10 and clamping plate 211 are made of high-strength plastic material, which can provide sufficient force to fix the plate without leaving scratches when clamping. A rubber plate 12 is fixedly connected to one side of clamping plate 10 and clamping plate 21, which can provide good friction to prevent slippage and avoid scratching the surface of the plate. Connecting components are provided inside clamping plate 10 and rubber plate 12.
[0034] Reference Figure 1 , Figure 4 and Figure 5The connecting assembly includes two hollow pillars 13 and pins 14. The two hollow pillars 13 are respectively disposed inside clamping plate 10 and clamping plate 2 11. The bottom ends of the two pins 14 are fixedly connected to the top ends of the two hollow pillars 13. The two pins 14 are slidably connected inside sliding rod 1 6 and sliding rod 2 7. A sliding column 15 is slidably connected inside the hollow pillars 13. The dynamic movement of the sliding column 15 can directly control the clamping and releasing of the clamping assembly. A connecting column 16 is fixedly connected to the top end of the sliding column 15. A cone block 17 is fixedly connected to the outer wall of the connecting column 16. A connecting ring 19 is fixedly connected to the outer wall of the sliding column 15. A retaining bead 18 is slidably connected inside the pins 14. The cone block 17 and the retaining bead 18 are in contact. 5. A spring 20 is fitted on the outer wall. The two ends of the spring 20 are fixedly connected to the hollow column 13 and the connecting ring 19, respectively. A button 21 is fixedly connected to the bottom of the sliding column 15. The button 21 is slidably connected inside the hollow column 13. Pressing the button 21 can effectively compress the spring 20, causing the cone block 17 to disengage from the retaining ball 18 and release the connecting structure, thereby simplifying the disassembly process. After releasing the button 21, the sliding column 15 inside the hollow column 13 will be forced by the reaction force of the spring 20 to press the outer wall cone block 17 of the connecting column 16 back against the pin 14, thereby making the retaining ball 18 tightly clamp the connection between the pin 14 and the sliding rod. In this way, the operator can easily replace and maintain the clamp.
[0035] Working principle: When using this plate handling fixture, the handle 3 makes it easy for the operator to hold the fixture. When the motor 2 is started, its output end drives the gear 4 to rotate. Because the gear 4 meshes with the rack 8 on the inner wall of slide rod 1 6 and slide rod 2 7, and the limiting block 5 at the bottom of the motor 2 is slidably connected in the limiting groove 9 of slide rod 1 6 and slide rod 2 7, the movement direction of slide rod 1 6 and slide rod 2 7 can be restricted, so that slide rod 1 6 and slide rod 2 7 slide in the opposite direction along the bottom of the support plate 1. Adjust the distance between clamping plate 1 10 and clamping plate 2 11 to match the width of the plate. The rubber plate 12 on one side of clamping plate 1 10 and clamping plate 2 11 directly contacts the plate, and the flexibility of the rubber avoids scratching the surface of the plate.
[0036] When the clamp needs to be disassembled and maintained, first press button 21 to compress spring 20, causing cone block 17 to disengage from retaining ball 18. Then insert pin 14 into slide bar and release button 21. The slide bar 15 inside hollow column 13 is subjected to the elastic force of spring 20, causing cone block 17 on the outer wall of connecting column 16 to press retaining ball 18 inside pin 14. Retaining ball 18 locks the connection between pin 14 and slide bar, facilitating the disassembly and replacement of clamp, ensuring continuous and effective scratch protection of clamp, and enabling clamp to complete plate handling operations efficiently and safely.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
