Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, specifically to a small flange clamping device. Background Technology

[0002] A flange, also called a flange plate or flange, is a part used to connect shafts. It is used to connect pipe ends, and also used on equipment inlets and outlets to connect two pieces of equipment. A flange connection is to fix two pipes, fittings or equipment to a flange plate respectively, put a flange gasket between the two flange plates, and tighten them together with bolts to complete the connection. Small flanges are usually used in places where space is relatively small.

[0003] For small flanges, due to their relatively small size, the applicable clamps are usually simple and the design is relatively basic. Simple clamps may not be able to fully fit the shape and size of the small flange, which limits their use and can easily cause the small flange to wobble or shift during the welding process, thus affecting the welding quality. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a small flange clamping device, which can effectively solve the problem that the clamps in the existing technology cannot fully fit the shape and size of the small flange, resulting in shaking or displacement during the welding process, thus affecting the welding quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a small flange clamping device, including a base. A rectangular groove is formed inside the base. Two sliding grooves are formed on each side of the rectangular groove. A connecting groove is formed at the top of the sliding groove. A sliding seat is slidably installed inside the rectangular groove. Multiple limiting grooves are formed at the top of the sliding seat, arranged in pairs. A limiting block is slidably installed inside each limiting groove. A connecting column is fixedly connected to the top of the limiting block. A connecting rod is fixedly connected to the top of the connecting column. The connecting rod is slidably installed inside the sliding groove. A support column is fixedly installed on one side of the top of the connecting rod. The top of the support column passes through the connecting groove. A clamping rod is fixedly connected to the top of the support column. A clamping block is fixedly connected to the side wall of the clamping rod. A driving mechanism is provided on one side of the sliding seat.

[0007] According to the above-mentioned small flange clamping device, the driving mechanism includes a connecting block, which is mounted on the top of the sliding seat. An installation box is fixedly installed on the side wall of the base, and a cylinder is fixedly installed inside the installation box. The output end of the cylinder passes through the installation box and the side wall of the base and is fixedly connected to the side wall of the connecting block.

[0008] According to the above-mentioned small flange clamping device, the limiting groove is inclined, and two adjacent limiting grooves form a "V" shape.

[0009] According to the above-mentioned small flange clamping device, the top of the base is provided with a placement groove, which is located directly below the two clamping blocks.

[0010] According to the above-mentioned small flange clamping device, the inside of each clamping block is provided with a protective pad.

[0011] According to the above-mentioned small flange clamping device, the limiting block is rhomboid in shape.

[0012] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0013] When the sliding seat is moved, the limiting block moves within the limiting groove. Because the connecting rod slides within the groove, the support column at the top of the connecting rod moves the two clamping rods away from or towards each other. This ultimately causes the two clamping blocks to move away from or towards each other, releasing or clamping the small flange. Compared to current simple clamps, this method can clamp and fix small flanges of different sizes, avoiding the impact of welding on the small flange. Simultaneously, the cylinder moves the connecting block, which in turn moves the sliding seat, causing the two clamping rods to move away from or towards each other, releasing or clamping the small flange.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Example: Refer to Figures 1 to 5 A small flange clamping device includes a base 1. A rectangular groove 4 is formed inside the base 1. Two sliding grooves 5 are formed on both sides of the rectangular groove 4. A connecting groove 3 is formed at the top of the sliding groove 5. A sliding seat 6 is slidably installed inside the rectangular groove 4. Multiple limiting grooves 7 are formed at the top of the sliding seat 6, arranged in pairs. The limiting grooves 7 are inclined, and corresponding pairs of limiting grooves 7 form a "V" shape. Limiting blocks 8 are slidably installed inside each limiting groove 7. The limiting blocks 8 are rhomboid in shape. A connecting column 9 is fixedly connected to the top of the limiting block 8. A connecting rod 10 is fixedly connected to the top of the connecting column 9. The connecting rod 10 is slidably installed inside the sliding groove 5. A support column 11 is fixedly installed on one side of the top of the connecting rod 10. The top of the support column 11 penetrates the connecting groove 3. A clamping rod 14 is fixedly connected to the top, and a clamping block 15 is fixedly connected to the side wall of the clamping rod 14. Each clamping block 15 is equipped with a protective pad. A driving mechanism is provided on one side of the sliding seat 6. The driving mechanism pulls the sliding seat 6 towards the cylinder 12, so the limiting block 8 slides inside the limiting groove 7. Since the connecting rod 10 slides in the sliding groove 5, when the limiting block 8 moves in the limiting groove 7, the connecting rod 10 moves in the sliding groove 5, driving the support column 11 to move inside the connecting groove 3, so that the two clamping rods 14 move away from each other, and the two clamping blocks 15 move away from each other. Then, the small flange is placed between the two clamping blocks 15, and the driving mechanism is used to reset the sliding seat 6. Finally, the two clamping rods 14 are driven to move closer to each other, and the clamping blocks 15 move closer to each other to clamp the small flange, which facilitates welding later.

[0024] Specifically, refer to Figure 2 and Figure 5 The driving mechanism includes a connecting block 13, which is installed on the top of the sliding seat 6. A mounting box 2 is fixedly installed on the side wall of the base 1. A cylinder 12 is fixedly installed inside the mounting box 2. The output end of the cylinder 12 passes through the mounting box 2 and the side wall of the base 1 and is fixedly connected to the side wall of the connecting block 13. The cylinder 12 is driven. Since the connecting block 13 is installed on the top of the sliding seat 6, the sliding seat 6 can be moved in the rectangular groove 4, so that the two clamping blocks 15 clamp the small flange.

[0025] Furthermore, refer to Figure 1 and Figure 4 The base 1 has a placement groove 16 on its top. The placement groove 16 is located directly below the two clamping blocks 15. The small flange can be placed inside the placement groove 16 and then clamped and secured by the clamping blocks 15.

[0026] The working principle of this utility model is as follows:

[0027] First, drive cylinder 12. Since connecting block 13 is installed on top of sliding seat 6, it can drive sliding seat 6 to move within rectangular groove 4. Then, limit block 8 slides within limit groove 7. Since connecting rod 10 slides within sliding groove 5, when limit block 8 moves within limit groove 7, connecting rod 10 moves within sliding groove 5, driving support column 11 to move within connecting groove 3, causing the two clamping rods 14 to move away from each other. Then, the two clamping blocks 15 move away from each other. Then, place the small flange to be processed inside groove 16, between the two clamping blocks 15. Start cylinder 12 again to drive sliding seat 6 to reset. Then, limit block 8 moves within limit groove 7 until it resets. Then, connecting rod 10 drives support column 11 to reset. Finally, it drives the two clamping rods 14 to move closer to each other, and the clamping blocks 15 move closer to each other to clamp the small flange, facilitating subsequent welding.

[0028] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
