Description

Technical Field

[0002] Sheet metal is a common mechanical part. During processing, it needs to be fixed on the machine tool. Generally, the position of the clamping plate is adjusted by cooperating with the threaded rod so that the sheet metal is clamped between the clamping plates to fix the sheet metal and facilitate subsequent processing of the sheet metal.

[0003] When sheet metal is cut or trimmed, it needs to be clamped and fixed. Existing clamping devices, such as patent number CN202310844320.4, are for forging sheet metal processing.

The end of the adjustment component is provided with an end clamping member, and the front and rear ends of the adjustment component are movably connected to front and rear clamping members. The output shaft of the hydraulic cylinder extends, driving the slide to slide upward in the slide rail, the rotating shaft synchronously moves upward, driving the sheet metal upward, and then the handle is held to drive the rotating shaft to rotate, thereby driving the sheet metal synchronously. When the turntable rotates 90 degrees with the rotating shaft, the slide is engaged in the V-shaped groove to stabilize the current position of the rotating shaft. When the sheet metal rotates 180 degrees, it stabilizes in the current state, thereby achieving the purpose of convenient flipping after clamping and fixing the sheet metal.

[0025] See also Figure 1-3 , a clamping device for sheet metal processing, comprising a base 1, a workbench 2, a movable tool 3, a transverse extrusion tool 4 and a longitudinal extrusion tool 5;

[0026] The workbench 2 is arranged above the base 1 , and four first chutes 21 are symmetrically provided on both sides of the workbench 2 . There are four movable toolings 3 , which are respectively arranged in the four first chutes 21 .

[0027] The transverse extrusion tooling 4 and the longitudinal extrusion tooling 5 are both arranged on one side of the mobile tooling 3, and the transverse extrusion tooling 4 performs extrusion limiting on both sides of the sheet metal part, and the longitudinal extrusion tooling 5 performs extrusion limiting on the front side of the sheet metal part. When the sheet metal part is processed, since the existing clamping device is side clamping, and as the product is different, the side processing causes the clamping position to affect the side processing. The present invention arranges both the transverse extrusion tooling 4 and the longitudinal extrusion tooling 5 on the mobile tooling 3. During processing, the clamping position can be changed according to the drawing, and the mobile tooling 4 can be moved when it is about to reach the processing point, so as to achieve the goal of not affecting the processing and maintaining clamping.

[0028] The movable tooling 3 includes a first driving motor 31, which is arranged in the first slide 21. The driving shaft of the first driving motor 31 is connected to the first screw rod 32, and the other end of the first screw rod 32 is connected to the first slide 21 with a bearing. The first screw rod 32 is rotatably connected to the L-shaped plate 33, and the L-shaped plate 33 is slidably connected in the first slide 21 under the action of the first screw rod 32. Since there are four movable toolings 3, there are two clamping points on each side when the sheet metal is processed. When one side needs to be processed, the first driving motor 31 is used to rotate the first screw rod 32, and the first screw rod 32 is used to rotate the L-shaped plate 33 to move horizontally, thereby achieving the effect of adjusting the position of the horizontal extrusion tooling 4 and the longitudinal extrusion tooling 5.

[0029] The transverse extrusion tooling 4 includes a positioning plate 41, one side of the positioning plate 41 is detachably connected to the L-shaped plate 33, and the other side of the positioning plate 41 is detachably connected to the cylinder 42. The extended end of the cylinder 42 is detachably connected to the extrusion plate 43, and the extrusion plate 43 extrude the sheet metal. The transverse extrusion tooling 4 uses the extension of the cylinder to control the extrusion plate 43 to extrude the sheet metal, and at the same time uses the cylinder 42 to control the clamping force of the sheet metal.

[0030] The longitudinal extrusion tooling 5 includes a transverse plate 51, a second slide groove 52 is provided in the middle of the transverse plate 51, and the longitudinal plate 53 is slidably connected in the second slide groove 52. The second slide groove 52 is provided with a longitudinal plate 53, and the longitudinal plate 53 is detachably connected to the second cylinder 54 at the bottom. A third slide groove 55 is provided in the middle of the L-shaped plate 33, and the second cylinder 54 is arranged at the bottom of the third slide groove 55, and the transverse plate 51 is slidably connected to the third slide groove 55. Fourth slide grooves 565 are provided on both sides of the second slide groove 52, and two ridges 564 are symmetrically provided on both sides of the longitudinal plate 53. The two ridges 564 are slidably connected to the fourth slide groove 565; a contraction component 56 is provided on one side of the longitudinal plate 53, and the other end of the contraction component 56 is detachably connected to the top of the transverse plate 51. A third cylinder 57 is provided below the transverse plate 51, and the lower end of the third cylinder 57 is detachably connected to the pressing plate 58. A rubber plate 59 is detachably connected to the bottom of the pressing plate 58, and the shape of the rubber plate 59 is the same as that of the pressing plate 58.

[0031] The retraction assembly 56 includes a second positioning plate 561, which is detachably connected to the horizontal plate 51. One side of the second positioning plate 561 is connected to the second screw rod 562 by a bearing, and the second screw rod 562 is rotatably connected to the vertical plate 53. One side of the vertical plate 53 is connected to the rotating ring 563 by a bearing, and the rotating ring 563 is internally screwed and connected to the second screw rod 562. A scale 511 is provided on the side of the horizontal plate 51, and the scale 511 is slidably connected to the L-shaped plate 33.

[0032] Operating principle: When the clamping device of the present invention is in use, the first drive motor 31 is first used to rotate the first screw rod 32, and the first screw rod 32 is spirally connected to the L-shaped plate 33, so that under the action of the first drive motor 31, the four L-shaped plates 33 perform corresponding lateral movements as needed, thereby achieving the effect of avoiding the cutting point. The existing clamping device is fixed and can only be disengaged during cutting. Once the sheet metal is disengaged, when it is fixed on one side, the sheet metal will deviate to a certain extent, thereby affecting the accuracy of sheet metal processing.

[0033] When the L-shaped plate 33 reaches the designated position, the cylinder 42 is extended accordingly. Since the extrusion plate 43 is located at the extended end of the cylinder, the extrusion plate 43 squeezes the corresponding side wall of the sheet metal, thereby achieving lateral clamping of the sheet metal.

[0034] When the thickness of the sheet metal is relatively thin, the middle part of the sheet metal is prone to outward deformation due to the lateral forces on both sides. In order to prevent this from happening and to achieve a better clamping effect on the sheet metal, a longitudinal extrusion tool 5 is set up, and the contraction of the third cylinder 57 is used to realize the pressure plate 58 to squeeze the upper part of the sheet metal. Then, when the cylinder 42 performs side clamping, due to the action of the longitudinal extrusion tool 5, the thrust required to achieve the deformation of the sheet metal is greatly increased.

[0035] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiment without creative contribution as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
