Description

Technical Field

[0001] The utility model belongs to the technical field of clamps, and in particular relates to an adjustable clamp for processing steel plates. Background Art

[0002] When the operator is processing the steel plate, the operator may perform processes such as welding, cutting, bending, and punching on the steel plate. When the operator is processing the plate, in order to ensure the stability of the steel plate processing, the operator may use a clamp to fix the steel plate to improve the stability of the operator's processing of the steel plate. Therefore, it can be seen that the existing clamps basically meet people's practical needs, but the following problems still exist.

[0003] When the operator uses the clamp to clamp the steel plate, the operator places the plate on the loading rack, and then the operator takes the clamp so that the clamp clamps the steel plate on the loading board. However, when the operator fixes the bent steel plate, the operator may not be able to place the clamp on the surface of the plate because the plate is bent on all sides, so the operator cannot fix the plate on the loading board through the clamp. For this reason, we propose an adjustable clamp for steel plate processing. Utility Model Content

[0004] The utility model provides an adjustable clamp for processing steel plates, which drives a rotating rod to rotate on a ring surface through a supporting plate, and adjusts the angles of a second clamping plate and a first clamping plate arranged on the supporting plate surface, so that the second clamping plate and the first clamping plate can clamp the bent edges of the plate around, thereby improving the clamping range of the clamp.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable steel plate processing fixture, comprising a processing plate, symmetrically provided with avoidance grooves at both end portions of the processing plate, and a support plate is inserted in the middle of the avoidance groove, a sleeve is fixed to the end portion of the support plate, and a rotating rod fixed on the inner wall of the avoidance groove passes through the middle of the sleeve, the rotating rod and the sleeve are both snap-connected, a first clamping plate is sliding on the surface of the support plate, and a second clamping plate is elastically connected to the surface of the first clamping plate, a mounting plate is provided on one side where the second clamping plate and the first clamping plate are fitted to each other, and a rubber block is fitted on the surface of the mounting plate, a limiting plate is fixed to the end of the support plate, and the limiting plate is fixed to the inner wall of the avoidance groove.

[0008] Furthermore, handles are fixed on the surfaces of the second clamping plates, and the surfaces of the handles are provided with a plurality of groups of semicircular grooves.

[0009] Furthermore, a first spring groove is opened in the middle of the rotating rod, and a first spring and a positioning button are respectively arranged inside the first spring groove, and the two side ends of the first spring are respectively abutted between the inner wall of the first spring groove and the surface of the positioning button, and the ends of the positioning button are all passed through the ring.

[0010] Furthermore, the ends of the positioning buttons are all configured to be conical, and the surface of the collar is provided with a plurality of groups of conical through holes configured to be connected to the ends of the positioning buttons.

[0024] Example:

[0025] See also Figure 1 - Figure 6A clamp for processing an adjustable steel plate comprises a processing plate 1, avoidance grooves 9 are symmetrically opened at the ends of both sides of the processing plate 1, and a support plate 2 is inserted in the middle of the avoidance grooves 9, a collar 6 is welded at the end of the support plate 2, and a rotating rod 5 welded on the inner wall of the avoidance groove 9 is penetrated in the middle of the collar 6, the rotating rod 5 and the collar 6 are snap-connected, a first clamping plate 8 is slid on the surface of the support plate 2, and a second clamping plate 10 is elastically connected to the surface of the first clamping plate 8, a mounting plate 11 is arranged on one side where the second clamping plate 10 and the first clamping plate 8 are bonded to each other, and a rubber block 12 is hot-melt bonded to the surface of the mounting plate 11, and the support plate 2 is welded to the inner wall of the avoidance groove 9. A limit plate 4 is fixed at the end of the plate 2, and the limit plate 4 is fixed on the inner wall of the avoidance groove 9. When the operator clamps the plate, the operator places the plate on the processing plate 1, and the operator first pulls the second clamping plate 10. The operator first pushes the support plate 2, so that the support plate 2 drives the ring 6 to rotate on the surface of the rotating rod 5, and when the rotating rod 5 rotates on the surface of the ring 6, the support plate 2 drives the first clamping plate 8 and the second clamping plate 10 to move. When the first clamping plate 8 and the second clamping plate 10 move to the appropriate position, the operator pulls the second clamping plate 10, and the second clamping plate 10 moves on the surface of the first clamping plate 8, so that the first clamping plate 8 and the second clamping plate 10 move to the first clamping plate 8. The second clamping plate 10 is separated from the first clamping plate 8, and then the operator places the plate between the first clamping plate 8 and the second clamping plate 10. After the operator places the plate between the second clamping plate 10 and the first clamping plate 8, the operator releases the second clamping plate 10. Under the action of the elastic force of the second clamping plate 10, the second clamping plate 10 clamps the plate on the surface of the first clamping plate 8, fixes the plate on the processing plate 1, and pushes the support plate 2 by the operator, and the support plate 2 drives the ring 6 to rotate on the surface of the rotating rod 5, so as to adjust the angle between the support plate 2 and the processing plate 1, so that the second clamping plate 10 and the first clamping plate 8 can be adjusted. The plate 8 can clamp the plate with bent edges, and when the operator clamps the flat plate, the operator first pulls the second clamping plate 10, and the second clamping plate 10 moves on the first clamping plate 8 to separate the second clamping plate 10 and the first clamping plate 8, and then the operator places the plate between the second clamping plate 10 and the first clamping plate 8, and then the operator releases the second clamping plate 10, and under the action of the elastic force, the second clamping plate 10 clamps the plate on the first clamping plate 8, thereby facilitating the operator to clamp the flat plate and improving the operator's ability to clamp plates with different bent edges.

[0026] In other embodiments, a traction block 20 is welded to one side of the mounting plate 11, the first clamping plate 8 and the second clamping plate 10, and the surface of the traction block 20 is provided with a traction groove 19 opened on the second clamping plate 10. When the operator clamps the plate with the first clamping plate 8 and the second clamping plate 10, in order to avoid scratches when the first clamping plate 8 and the second clamping plate 10 are clamped on the plate, the operator moves the rubber block 12, and the rubber block 12 drives the traction block 20 to move through the mounting plate 11, so that the traction block 20 and the traction groove 19 are aligned with each other. When the traction block 20 and the traction groove 19 are aligned with each other, the operator pushes the mounting plate 11, and the mounting plate 11 drives the traction block 20 to move, and the traction block 20 is inserted into the traction groove 19, and the operator pushes the mounting plate 11 to move, and the mounting plate 11 drives the traction block 20 to move, and the traction block 20 is inserted into the traction groove 19.

[0027] In other embodiments, a slider 18 is welded to one side of the first clamping plate 8 and the support plate 2, and the surface of the slider 18 is sleeved with a slide groove 3 opened on the support plate 2, and a threaded rod 16 penetrating one end of the slide groove 3 is welded to the middle of the slider 18, and a nut 17 is installed on the surface of the threaded rod 16. When the operator needs to adjust the clamping position of the second clamping plate 10 and the first clamping plate 8 on the plate, the operator first screws the nut 17 so that the nut 17 and the threaded rod 16 are threadedly matched with each other, so that the nut 17 is moved out from the surface of the support plate 2. After the nut 17 and the threaded rod 16 no longer fix the slider 18, the operator pulls Move the first clamping plate 8, the first clamping plate 8 drives the slider 18 to slide in the slide groove 3, so that the slider 18 drives the first clamping plate 8 to slide on the surface of the support plate 2, and the first clamping plate 8 and the second clamping plate 10 are moved to the appropriate position. Then the operator screws the nut 17 again to make the nut 17 and the threaded rod 16 threadedly cooperate, make the nut 17 and the surface of the support plate 2 fit each other, and squeeze the slider 18 into the slide groove 3, so as to fix the first clamping plate 8 on the support plate 2, which is convenient for fixing the position of the first clamping plate 8, so that the operator can adjust the clamping position of the first clamping plate 8 and the second clamping plate 10 on the plate.

[0028] In other embodiments, a handle 7 is welded to the surface of the second splint 10, and a plurality of groups of semicircular grooves are provided on the surface of the handle 7. When the operator pulls the second splint 10, the operator holds his hand on the surface of the handle 7. After the operator holds his hand on the surface of the handle 7, the plurality of groups of semicircular grooves provided on the surface of the handle 7 facilitate increasing the friction force of the operator's hand on the surface of the handle 7, thereby improving the stability of the operator's hand on the surface of the handle 7. Then, the operator pulls the handle 7, and the handle 7 drives the second splint 10 to move, making it convenient for the operator to pull the second splint 10 to move.

[0029] In other embodiments, a first spring groove 15 is provided in the middle of the rotating rod 5, and a first spring 13 and a positioning button 14 are respectively provided inside the first spring groove 15, and the two side ends of the first spring 13 are respectively abutted between the inner wall of the first spring groove 15 and the surface of the positioning button 14, and the end of the positioning button 14 passes through the collar 6, and the end of the positioning button 14 is set to a cone shape. The surface of the collar 6 is provided with a plurality of groups of conical through holes set with the end of the positioning button 14. When the operator pulls the support plate 2 to move, the support plate 2 drives the collar 6 to slide on the surface of the rotating rod 5, and when the collar 6 slides on the surface of the rotating rod 5, the inner wall of the conical through hole provided on the inner wall of the collar 6 and the cone set at the end of the positioning button 14 fit each other, so that the inner wall of the conical through hole provided on the surface of the collar 6 pushes the positioning button 14 to move, and the positioning button 14 slides in the first spring groove 15, and the positioning button 14 moves in the first spring groove 15. When sliding, the positioning button 14 squeezes the first spring 13, causing the first spring 13 to undergo elastic deformation. After the first spring 13 undergoes elastic deformation, the first spring 13 avoids the positioning button 14, causing the positioning button 14 to enter the first spring groove 15, and the positioning button 14 moves out of the through hole opened on the surface of the collar 6. After the positioning button 14 no longer fixes the collar 6 and the rotating rod 5, the rotating rod 5 can rotate on the surface of the collar 6. When the collar 6 drives another through hole opened on the surface to move to the front end of the positioning button 14, the positioning button 14 is no longer restricted by the inner wall of the collar 6, and the positioning button 14 no longer presses the first spring 13. The elastic deformation of the first spring 13 is restored, and the first spring 13 pushes the positioning button 14 to move, causing the positioning button 14 to be inserted into the through holes opened around the collar 6, fixing the position of the collar 6, thereby fixing the position of the support plate 2, and improving the stability of the operator when using the support plate 2.

[0030] In other embodiments, both ends of the second clamping plate 10 are welded with fixing blocks 23, and the middle of the fixing blocks 23 is provided with second spring grooves 21, and the second spring grooves 21 are embedded with traction rods 22, and the surfaces of the traction rods 22 are wound with second springs 24, and both ends of the second springs 24 are respectively abutted between the inner wall of the second spring grooves 21 and the surfaces of the traction rods 22, and the ends of the traction rods 22 are welded with fixing plates 25, and the fixing plates 25 are welded to the first clamping plate 8. When the operator pulls the second clamping plate 10 to move, the second clamping plate 10 drives the second spring grooves 21 to move through the fixing blocks 23, so that the second spring grooves 21 slide on the surfaces of the traction rods 22, and the second spring grooves 21 are moved on the surfaces of the traction rods 22. During sliding, the second spring groove 21 squeezes the second spring 24, causing the second spring 24 to undergo elastic deformation. After the second spring 24 undergoes elastic deformation, the second spring 24 avoids the traction rod 22, so that the second spring groove 21 can slide on the surface of the traction rod 22, separating the second clamping plate 10 from the first clamping plate 8. When the operator releases the second clamping plate 10, the second clamping plate 10 no longer squeezes the second spring groove 21 through the fixing block 23, and the elastic deformation of the second spring 24 is restored. The second spring 24 drives the fixing block 23 to move through the second spring groove 21, so that the fixing block 23 drives the second clamping plate 10 to move, and the second clamping plate 10 and the first clamping plate 8 are fitted together, thereby clamping the plate.
