Description

Technical Field

[0001] This utility model relates to the field of stainless steel processing technology, specifically a clamping device suitable for processing corrosion-resistant stainless steel. It can also be applied to the processing of other similar stainless steel sheets. Background Technology

[0002] Stainless steel sheets have a smooth surface, high plasticity, toughness, and mechanical strength, and are resistant to corrosion from acidic and alkaline gases, solutions, and other media. It is an alloy steel that does not easily rust. During stainless steel production, it requires processing, including drilling, grinding, and cutting, all of which necessitate the use of clamping devices to hold and secure the stainless steel sheets. Existing clamping devices, however, often obstruct the stainless steel on both sides, hindering processing and exhibiting poor adaptability, unable to accommodate stainless steel sheets of varying sizes.

[0003] For example, CN218696186U describes a clamping device for processing stainless steel plates, including a support column. A processing table is fixedly connected to one side of the support column, and a clamping component is provided on one side of the processing table. The clamping component includes a frame, a rotating shaft is rotatably connected to one side of the frame, a lead screw is fixedly connected to one side of the rotating shaft, a moving plate is threadedly connected to one side of the lead screw, a sliding bracket is fixedly connected to the side of the moving plate, a connecting rod is fixedly connected to the top surface of the moving plate, a limit post is fixedly connected to the side of the connecting rod, and a clamping frame is fixedly connected to the top surface of the connecting rod. This technical solution can clamp the steel plate by ensuring close contact between the anti-slip pad and the steel plate, and can completely expose the surface of the steel plate, preventing the steel plate from having processing dead corners and eliminating the need for secondary processing. This not only reduces the workload of workers but also greatly improves work efficiency.

[0004] The aforementioned technology has the drawback of obstructing the stainless steel plate on both sides during clamping operations, making it impossible to perform operations such as deburring on the stainless steel plate. This requires secondary operations by the operator. In addition, the clamping frame structure is fixed, and the operator cannot adjust the clamping length according to the length of the stainless steel plate. The overall clamping effect is limited. Based on the above problems, there may already be technical means to solve the above technical solutions. This case aims to provide an alternative or replacement technical means. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a clamping device suitable for processing corrosion-resistant stainless steel, which has the advantages of easy operation and wide applicability.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a clamping device suitable for processing corrosion-resistant stainless steel, comprising a table-shaped frame, characterized in that a rectangular frame is provided on the underside of the tabletop of the frame, a first bidirectional screw is rotatably connected to the rectangular frame, the first bidirectional screw extends in the opposite direction along the width of the tabletop, strip-shaped openings are provided at both ends of the upper side of the frame, a pair of moving blocks are slidably connected to the first bidirectional screw, and connecting parts are provided at both ends of the upper side of the moving blocks, extending from the strip-shaped openings to the top of the tabletop and connecting to the strip-shaped base;

[0007] The strip seat has a groove on its upper side, and a second bidirectional screw is rotatably connected in the groove. Clamping seats are slidably connected on both sides of the second bidirectional screw. The clamping seats are L-shaped seats. A positioning plate is provided on the back of the clamping seat. Positioning holes are evenly opened on the upper side of the strip seat. A pin corresponding to the positioning hole is inserted into the upper side of the positioning plate. A groove is provided on the horizontal plate of the clamping seat, and a roller group is rotatably connected inside the groove.

[0008] In the above scheme, a handwheel is provided on one side of both the first bidirectional screw and the second bidirectional screw.

[0009] In the above scheme: guide rods are respectively provided at both ends below the tabletop of the rack, guide grooves are provided on both sides of the rectangular frame, and the movable block passes through the guide grooves on both sides and is slidably connected to the guide rods.

[0010] In the above scheme: a reinforcing rib is provided at the connection between the vertical plate of the clamping seat and the positioning piece.

[0011] In the above scheme: the clamping seat vertical plate is provided with an anti-slip pad.

[0012] The clamping device for processing corrosion-resistant stainless steel provided by this utility model has the following beneficial effects:

[0013] 1. This technical solution uses two sets of clamping seats with adjustable spacing on the upper side of the frame. Compared with the prior art, this solution can adjust the spacing between the clamping seats according to the length of the stainless steel plate, and fix the position of the adjusting seats after the adjustment is completed. It has a wide range of applications and is easy to adjust.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Example 1

[0021] Please see Figure 1-3 A clamping device suitable for processing corrosion-resistant stainless steel includes a frame 1, which is a table-shaped frame. A rectangular frame 2 is provided under the tabletop of the frame 1, located between four legs, and the size of the rectangular frame matches the size of the tabletop between the four legs. A first bidirectional screw 3 is rotatably connected to the rectangular frame 2, extending in the opposite direction along the width of the tabletop, with one end extending outside the rectangular frame 2 and connected to a handwheel 11. A strip-shaped opening is provided on the upper side of the frame 1 near both the left and right ends, extending in the opposite direction along the width of the tabletop. A pair of moving blocks 4 are slidably connected to the first bidirectional screw 3, extending along the length of the tabletop. Each moving block 4 has connecting parts at both ends on its upper side, extending from the strip-shaped opening to the top of the tabletop and connected to a strip-shaped seat 5, which extends along the length of the tabletop. A strip-shaped seat 5 is provided on each side of the tabletop.

[0022] Each strip seat 5 has a strip groove on its upper side, and a second bidirectional screw 6 is rotatably connected in the strip groove. One end of the second bidirectional screw 6 extends into the strip groove and is connected to the handwheel 11. Clamping seats 7 are slidably connected to both sides of the second bidirectional screw 6. The clamping seats 7 are L-shaped clamps formed by vertical plates and horizontal plates. The clamping seats 7 on the two strip seats 5 are arranged opposite to each other. A positioning piece 8 is provided on the back of the clamping seat 7. A reinforcing rib 13 is provided at the connection between the clamping seat 7 and the positioning piece 8 to increase the overall strength of the clamping seat 7.

[0023] The strip seat 5 has evenly spaced positioning holes along its length on its upper side, and the positioning plate 8 also has corresponding positioning holes. The positioning plate 8 is fixed in the positioning holes on the strip seat 5 by a pin 9. The horizontal plate of the clamping seat 7 has a groove, and a roller group 10 is rotatably connected inside the groove. The inner side of the vertical plate of the clamping seat 7 is provided with an anti-slip pad 14. The anti-slip pad 4 is vertically arranged, and three anti-slip pads 14 are spaced apart on the inner side of the vertical plate.

[0024] During the processing of stainless steel plates, in order to ensure the stability of the processing, it is necessary to clamp and fix the stainless steel plates. At this time, the operator can use the handwheel 11 to rotate the second bidirectional screw 6 to move the two clamping seats 7 away from each other or closer together, and to match the distance between the two clamping seats 7 with the stainless steel plate. After the adjustment is completed, the operator inserts the pin 9 through the limiting piece and into the positioning hole, so as to fix the position of the clamping seat 7 and prevent the clamping seat 7 from shaking during subsequent clamping operations.

[0025] Then, by rotating the first bidirectional bolt through the handwheel 11, a pair of moving blocks 4 are driven to move closer to each other, and the strip seat 5 and the clamping seat 7 located on the upper side of the strip seat 5 are driven closer to each other. Then, through the cooperation of the clamping seat 7 and the anti-slip pad 14, the stainless steel plate can be clamped and fixed. The roller group 10 is used to reduce the friction between the lower side of the clamping seat 7 and the stainless steel plate, and increase the smoothness of clamping and fixing.

[0026] This invention employs a four-point clamping method to clamp and fix the stainless steel plate. Compared with existing technologies, this method can stably clamp the stainless steel plate while reducing obstruction on both sides of the plate, facilitating subsequent processing operations such as deburring and improving the processing effect. Furthermore, the spacing between the clamping seats 7 can be adjusted according to the length of the stainless steel plate, and the position of the adjusting seats can be fixed after adjustment. Overall, this invention has a wide range of applications and is easy to adjust.

[0027] Guide rods 12 are provided at both ends below the desktop of the frame 1. Guide grooves are provided on both sides of the rectangular frame 2. The moving block 4 passes through the guide grooves on both sides and is slidably connected to the guide rods 12 to increase the stability of the moving block 4 during movement.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
