Description

Technical Field

[0001] This utility model relates to the field of clamping and fixing, and in particular to a clamping and fixing device for manufacturing metal structures. Background Technology

[0002] Metal structure manufacturing is a production activity that uses metals such as iron, steel, or aluminum as the main materials to manufacture metal components and parts, as well as steel products for construction. This industry encompasses the manufacturing of products such as communication towers, power transmission line towers, metal bridge structures, and building steel structures. Characterized by their transportability and assemblability, these products are widely used in power transmission, communication infrastructure, and construction engineering. In the metal structure manufacturing process, clamping and fixing devices are crucial tools. They are typically used to fix workpieces, ensuring their stable and accurate position during processing. Clamping and fixing devices effectively improve production efficiency, prevent workpiece movement and deformation, and also ensure the safety of operators.

[0003] For example, the clamping and fixing device for manufacturing metal structures disclosed in Chinese Patent No. CN222697170U includes a support frame, a reinforcing rib fixedly connected to the middle of the outer surface of the support frame, an installation cabinet fixedly connected to the inside of the support frame, an operating table fixedly connected to the top of the support frame, an installation box fixedly connected to one side of the upper surface of the operating table, and a fixing device fixedly connected to the inside of the installation box.

[0004] The aforementioned device supports the main body of the device through a support frame, and a fixing device clamps the metal structure that needs to be fixed. The metal structure is placed on a fixing plate, and the telescopic rod extends and retracts according to the size of the metal. The fixing block clamps it to achieve the most stable effect. However, the aforementioned clamping and fixing device cannot adjust the angle of the clamped metal structure workpiece, which limits the processing flexibility of the clamped metal structure workpiece. Therefore, in order to address the above problems, a clamping and fixing device for manufacturing metal structures is proposed. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:

[0006] A clamping and fixing device for manufacturing metal structures includes a base plate; support blocks are fixedly arranged on both sides of the upper part of the base plate, and sliding holes are opened on the upper part of the support blocks. Inserted pins are slidably connected to the sliding holes. A support plate is fixedly arranged on the upper part of the two inserted pins. A spring is arranged on the outer side of the inserted pin. One end of the spring is connected to the support block, and the other end of the spring is connected to the bottom of the support plate. A driven wedge block is fixedly arranged below the support plate. A lifting drive mechanism is arranged on the base plate. A shaft tooth is rotatably arranged on the upper part of the support plate. A clamping plate is fixedly arranged on the shaft of the shaft tooth. An angle adjustment mechanism is arranged on the upper part of the support plate. A clamping and fixing mechanism is arranged on the clamping plate.

[0007] As an improvement to the above technical solution, the lifting drive mechanism includes a slide rail fixedly mounted on the base plate, the slide rail being located between the two support blocks, a slide plate slidably connected to the slide rail, a drive wedge block fixedly mounted above the slide plate, a side frame fixedly mounted on one side of the upper part of the base plate, a first electric push rod mounted on the side frame, the output end of the first electric push rod being slidably connected to the side of the drive wedge block, and the upper part of the drive wedge block being slidably connected to the driven wedge block.

[0008] As an improvement to the above technical solution, the angle adjustment mechanism includes a slot frame fixedly mounted on the support plate, a toothed plate slidably connected to the slot frame, the teeth on the toothed plate meshing with the teeth on the shaft teeth, a mounting base fixedly mounted above the base plate, and a second electric push rod fixedly mounted above the mounting base, the output end of the second electric push rod being fixedly connected to the toothed plate.

[0009] As an improvement to the above technical solution, the clamping and fixing mechanism includes a set of side slide grooves opened on the clamping plate, a slide rod fixedly installed in the side slide grooves, a central slide groove opened on the clamping plate, a bidirectional threaded rod rotatably installed in the central slide groove, a set of sliders slidably connected on the slide rods, a clamping plate fixedly installed above the corresponding sliders, a connecting block fixedly installed below the clamping plate, the connecting block being threadedly connected to two sections of threads on the bidirectional threaded rod, and a detachable chuck installed on the clamping plate.

[0010] As an improvement to the above technical solution, a pad is fixedly provided on the clamp, and the pad is provided with anti-slip texture.

[0011] As an improvement to the above technical solution, the central slide groove is arranged parallel to the side slide grooves, and the central slide groove is located between the two side slide grooves.

[0012] The beneficial effects of this utility model are:

[0013] 1. Through the structural design of the lifting drive mechanism, the first electric push rod is controlled to push the drive wedge block. At this time, the slide plate slides on the slide rail, and the drive wedge block slides against the driven wedge block, thereby lifting the support plate. As a result, the insert on the support plate slides in the sliding hole of the corresponding support block, and the spring on the outside of the insert is deformed, so that the support plate moves up and down stably, improving the flexibility of the device.

[0014] 2. By adjusting the angle of the angle adjustment mechanism, the angle of the metal workpiece fixed on the clamping mechanism can be adjusted by rotating the clamping plate, thereby improving the flexibility of the device.

[0015] 3. This utility model provides a clamping and fixing device for manufacturing metal structures. Through the structural setting of the clamping and fixing mechanism, the metal structure workpiece is stably clamped. Furthermore, the clamping plate is detachably equipped with a chuck, which can be replaced with different shapes to improve the flexibility of the device. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0023] Please refer to Figures 1-5 As shown, this utility model provides a clamping and fixing device for manufacturing metal structures. The electrical components in the device can be connected to an external controller and power supply for control. It includes a base plate 1; the base plate 1 is made of high-strength steel, and positioning holes are provided at its four corners for positioning the device. Support blocks 2 are fixedly installed on the upper two sides of the base plate 1. Sliding holes 3 are provided above the support blocks 2, and inserts 4 are slidably connected to the sliding holes 3. Support plates 5 are fixedly installed above the two inserts 4. Springs 6 are installed on the outer side of the inserts 4. One end of the spring 6 is connected to the support block 2, and the other end of the spring 6 is connected to the bottom of the support plate 5. A clamping device is fixedly installed below the support plate 5. The moving wedge block 7 and the base plate 1 are equipped with a lifting drive mechanism. The lifting drive mechanism is used to adjust the lifting of the clamping and fixing mechanism to improve the flexibility of the clamping and fixing device. The support plate 5 is rotatably equipped with a shaft tooth 8. The shaft tooth 8 is fixedly equipped with a clamping plate 18. The support plate 5 is equipped with an angle adjustment mechanism. Through the structure of the angle adjustment mechanism, the angle of the clamping and fixing mechanism can be adjusted by rotation, improving the flexibility of the clamping and fixing device. The clamping and fixing mechanism is equipped with a clamping and fixing mechanism. Through the structure of the clamping and fixing mechanism, it is used to clamp and position the metal structure workpiece, thereby facilitating further processing of the metal structure workpiece.

[0024] Furthermore, such as Figure 1 and Figure 3 As shown, the lifting drive mechanism includes a slide rail 9 fixedly mounted on the base plate 1, the slide rail 9 being located between two support blocks 2, a slide plate 10 slidably connected to the slide rail 9, a drive wedge block 11 fixedly mounted above the slide plate 10, a side frame 12 fixedly mounted on one side of the upper part of the base plate 1, a first electric push rod 13 mounted on the side frame 12, the output end of the first electric push rod 13 being slidably connected to the side of the drive wedge block 11, and the upper part of the drive wedge block 11 being slidably connected to the driven wedge block 7. By controlling the operation of the first electric push rod 13, the drive wedge block 11 is pushed. At this time, the slide plate 10 slides on the slide rail 9, and the drive wedge block 11 slides against the driven wedge block 7, thereby lifting the support plate 5. As a result, the insertion post 4 on the support plate 5 slides in the corresponding sliding hole 3 of the support block 2, and the spring 6 on the outside of the insertion post 4 is deformed, so that the support plate 5 moves up and down stably.

[0025] Furthermore, such as Figure 3As shown, the angle adjustment mechanism includes a slot frame 14 fixedly mounted on the support plate 5, a toothed plate 15 slidably connected to the slot frame 14, the teeth on the toothed plate 15 meshing with the teeth on the shaft tooth 8, a mounting base 16 fixedly mounted above the base plate 1, and a second electric push rod 17 fixedly mounted above the mounting base 16. The output end of the second electric push rod 17 is fixedly connected to the toothed plate 15. By controlling the operation of the second electric push rod 17, the toothed plate 15 is slid on the slot frame 14, thereby pushing the toothed plate 15 to rotate the shaft tooth 8, causing the clamping plate 18 above the shaft tooth 8 to rotate.

[0026] Furthermore, such as Figure 1 and Figure 5 As shown, the clamping and fixing mechanism includes a set of side slide grooves 19 opened on the clamping plate 18, in which a slide rod 20 is fixedly installed. A central slide groove 21 is opened on the clamping plate 18, in which a bidirectional threaded rod 22 is rotatably installed. A set of sliders 23 are slidably connected to the slide rod 20. A clamping plate 24 is fixedly installed above the corresponding front and rear sliders 23. A connecting block 25 is fixedly installed below the clamping plate 24. The connecting block 25 is threadedly connected to the two sections of threads on the bidirectional threaded rod 22. A detachable chuck 26 is installed on the clamping plate 24. The chuck 26 can be replaced with different shapes to improve the flexibility of the device. Through the structural setting of the clamping and fixing mechanism, the two clamping plates 24 are moved towards each other, thereby moving the position of the chuck 26, thereby clamping the metal workpiece.

[0027] Furthermore, such as Figure 5 As shown, a pad 27 is fixedly provided on the chuck 26. The pad 27 is provided with anti-slip texture. The pad 27 is made of rubber material, and the anti-slip texture on the pad 27 improves the stable clamping treatment of the metal structure workpiece.

[0028] Furthermore, such as Figure 5 As shown, the central slide 21 is arranged parallel to the side slides 19, and the central slide 21 is located between the two side slides 19. The lifting clamp 24 moves smoothly to clamp the metal workpiece.

[0029] Working principle: When the worker clamps the metal structural workpiece,

[0030] By using the structure of the clamping and fixing mechanism, the metal workpiece is stably clamped. By rotating the bidirectional threaded rod 22, the connecting block 25 below the clamping plate 24 slides in the central slide groove 21, and the sliders 23 on both sides below the clamping plate 24 move in the slide rods 20 of the side slide grooves 19, thereby moving the two clamping plates 24. The chucks 26 on the clamping plates 24 move towards each other to clamp the workpiece. The chucks 26 are detachably provided on the clamping plates 24, and the chucks 26 can be replaced with different shapes to improve the flexibility of the device.

[0031] By controlling the operation of the first electric push rod 13 through the structure of the lifting drive mechanism, the drive wedge block 11 is pushed. At this time, the slide plate 10 slides on the slide rail 9, and the drive wedge block 11 slides against the driven wedge block 7, thereby lifting the support plate 5. As a result, the insertion post 4 on the support plate 5 slides in the sliding hole 3 of the corresponding support block 2, and the spring 6 on the outside of the insertion post 4 is deformed, so that the support plate 5 can move up and down stably, improving the flexibility of the device.

[0032] By adjusting the angle mechanism, the second electric push rod 17 is controlled to slide the toothed plate 15 on the slot frame 14, thereby pushing the toothed plate 15 to rotate the shaft tooth 8, which in turn causes the clamping plate 18 above the shaft tooth 8 to rotate, thus improving the flexibility of the device.

[0033] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
