Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal punching and fixing, in particular to a fixing tool for punching a sheet metal part. Background Art

[0002] Sheet metal is a product processed by sheet metal technology. Sheet metal is a comprehensive cold processing technology for metal sheets (usually less than 6mm), including shearing, punching / cutting / compounding, folding, welding, riveting, splicing, forming (such as car body), etc. Sheet metal has the characteristics of light weight, high strength, conductivity (can be used for electromagnetic shielding), low cost, and good performance in large-scale mass production. When using sheet metal, in order to ensure the convenience of mutual installation, it is necessary to punch holes on the surface of the sheet metal. When punching, in order to ensure the stability of the punching, a fixed tool is needed. However, the current fixed tool only plays the role of clamping the sheet metal, and it is inconvenient to lift the sheet metal. As a result, when punching, either the sheet metal is placed on the workbench, which makes it easy to punch too deep and damage the workbench, or the sheet metal has to be lifted and then clamped by the fixed tool, which causes a workload for the staff.

DETAILED DESCRIPTION

[0020] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0021] Example

[0022] like Figure 1-Figure 3 As shown, an embodiment of the utility model proposes a fixed tool for punching sheet metal parts, including a workbench 1, a leakage hole 2 for chip removal after punching is opened on the top of the workbench 1, a pad 4 is installed on the inner wall of the leakage hole 2, and the pad 4 is used to support the workpiece, and a position-adjustable clamping member 5 is provided on the top of the workbench 1. The clamping member 5 includes a connecting seat 51 slidably connected to the top of the workbench 1, a rotatable support plate 52 is installed on the surface of the connecting seat 51, a rotatable fixed seat 53 is provided at the end of the support plate 52, and an L-shaped plate 54 is installed on one side of the fixed seat 53, and the L-shaped plate 54 is used to clamp the workpiece.

[0023] In the utility model, when the entire structure is used, the movement of the connecting seat 51 drives the support plate 52, the fixing seat 53 and the L-shaped plate 54 to move together. When the L-shaped plate 54 contacts the workpiece, the workpiece moves to the L-shaped plate 54 and then continues to move through the connecting seat 51. However, the L-shaped plate 54 cannot be horizontally displaced due to the obstruction of the workpiece. Then, the support plate 52 is respectively connected to the connecting seat 51 and the fixing seat 53 for rotation, so that the L-shaped plate 54 can be forced to move upward when pushed, thereby achieving the support of the workpiece, effectively improving the convenience of drilling.

[0024] Among them, the L-shaped plate 54 is arranged at one side of the workpiece in the shape of an arc surface 55, so that the workpiece can be better moved to the top of the L-shaped plate 54 when clamping.

[0025] In the present invention, by providing the L-shaped plate 54 with an arc surface 55, it is effectively ensured that the workpiece can be moved to the inner wall of the L-shaped plate 54 under the pressure of force, so as to facilitate the lifting of the workpiece.

[0026] A U-shaped rod 6 is installed at one side of the connecting seat 51 , and a driving member 7 is installed at the bottom of the workbench 1 . The driving member 7 is used to drive the movement of the U-shaped rod 6 .

[0027] In the utility model, the U-shaped rods 6 on both sides of the workpiece are driven by the provided driving member 7 to move relative to each other, thereby effectively ensuring the clamping effect of the clamping member 5 on the workpiece.

[0028] Among them, the driving member 7 includes a dual-axis motor 71 installed at the bottom of the raising member 4, a threaded rod 72 is installed at the output end of the dual-axis motor 71, a threaded tube 73 is threadedly connected to the surface of the threaded rod 72, and the end of the U-shaped rod 6 is connected to a connecting plate 61, and the threaded tube 73 is installed on the connecting plate 61.

[0029] In the utility model, when the dual-axis motor 71 is started, it effectively drives the threaded rod 72 to rotate. Since the threaded rod 72 and the threaded barrel 73 are in a threaded connection state, the position of the threaded barrel 73 can be adjusted. Then the connecting plate 61 is connected to the threaded barrel 73, so that the connecting plate 61 is driven by the threaded barrel 73 to drive the U-shaped rod 6 to move.

[0030] A rotatable rotating rod 3 is installed on the inner wall of the leakage hole 2, and the rotating rod 3 is used to play a supporting role when the clamping member 5 moves.

[0031] In the present invention, the rotating rod 3 is provided to support the workpiece when the clamping member 5 has not yet clamped the workpiece, thereby preventing the L-shaped plate 54 from falling due to gravity and affecting the clamping effect.

[0032] A support member 8 is installed at the bottom of the workbench 1 , a support rod 81 is installed at the bottom of the support member 8 , and an ash collecting box 9 is installed at the top of the support rod 81 .

[0033] In the present invention, when in use, the support rod 81 and the support member 8 play a supporting role, and the dust collecting box 9 is used to collect the debris after punching.
