Description

Technical Field

[0001] This utility model belongs to the field of sheet metal processing technology, specifically relating to a support fixture for preventing deformation during laser cutting of sheet metal parts. Background Technology

[0002] Sheet metal cutting technology originated in the traditional machining field, initially employing mechanical cutting methods such as shearing and stamping. With breakthroughs in laser technology, the industrial application of CO2 lasers in the 1970s ushered in a new era of high-precision cutting. The widespread adoption of fiber lasers in the 21st century further improved cutting efficiency and precision, making laser cutting the mainstream process in sheet metal processing. In the automotive manufacturing industry, laser cutting is used for the precision machining of body panels and structural components, with errors controllable within ±0.1mm. In the aerospace industry, it is used for cutting irregularly shaped parts made of aerospace materials such as aluminum alloys and titanium alloys. In the electronics and electrical industry, it is used for processing precision housings and heat dissipation components. Current technological development is evolving towards intelligence and flexibility. The use of real-time monitoring systems and adaptive fixtures solves the problem of thermal deformation in thin sheet metal cutting. The anti-deformation support fixture of this invention is an innovative achievement in line with this technological trend and can be widely applied to precision sheet metal machining scenarios in the aforementioned fields.

[0003] Traditional fixed fixtures use rigid clamping, which can easily cause thermal deformation of thin sheet metal parts under the high temperature of laser, affecting processing accuracy. When switching between different workpieces, traditional fixtures require repeated manual adjustments to the positioning, which seriously affects production efficiency. Therefore, a new type of anti-deformation support fixture for laser cutting of sheet metal parts has emerged. Utility Model Content

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Example

[0026] Reference Figures 1-4 This embodiment of the present invention provides a sheet metal laser cutting anti-deformation support fixture, comprising:

[0027] The moving mechanism 100 includes a support frame 101, casters 102 fixedly connected to the bottom of the support frame 101, a mounting bracket 103 fixedly connected to the inner wall of the support frame 101, and a jacking cylinder 104 adapted to be installed on the side wall of the support frame 101.

[0028] The fixing mechanism 200 includes a mounting plate 201 fixedly connected to the side wall of the mounting bracket 103, a mounting opening 202 opened on the side wall of the mounting plate 201, a card seat 203 fixedly connected to the inner wall of the mounting plate 201, a limiting seat 204 fixedly connected to the inner wall of the card seat 203, a fixing frame 205 fixedly connected to the side wall of the limiting seat 204, an abutting cylinder 206 fixedly connected to the side wall of the fixing frame 205, a top block 207 fixedly connected to the end of the abutting cylinder 206, an adjustment assembly 208 provided on the side wall of the mounting plate 201, and a clamping assembly 209 provided on the surface of the mounting plate 201.

[0029] Specifically, the adjustment assembly 208 includes a fixed seat 208a fixedly connected to the side wall of the mounting plate 201, and a push cylinder 208b fixedly connected to the side wall of the fixed seat 208a. The adjustment assembly 208 also includes a limiting rod 208c fixedly connected to the inner wall of the fixed seat 208a, and a movable seat 208d slidably connected to the surface of the limiting rod 208c. The adjustment assembly 208 also includes a mounting seat 208e fixedly connected to the side wall of the fixed seat 208a, and a mold 208f fixedly connected to the side wall of the mounting seat 208e.

[0030] Furthermore, the side wall of the movable seat 208d is fixedly connected to the end of the push cylinder 208b. When the push cylinder 208b is running, it will drive the mounting seat 208e to move. The mounting seat 208e is used in conjunction with the limit post to make the movement smoother.

[0031] Preferably, the clamping assembly 209 includes an abutment 209a fixedly connected to the inner wall of the mounting port 202, and a fixing cylinder 209b fixedly connected to the side wall of the abutment 209a. The clamping assembly 209 also includes a push plate 209c fixedly connected to the end of the fixing cylinder 209b, and an auxiliary cylinder 209d fixedly installed on the side wall of the mounting plate 201. The clamping assembly 209 also includes a stop block 209e fixedly connected to the end of the auxiliary cylinder 209d, and a cutting seat 209f fixedly connected to the side wall of the mounting plate 201.

[0032] It should be noted that there are two sets of auxiliary cylinders 209d, which are symmetrically arranged on the side wall of the mounting plate 201. The symmetrical design ensures that the device can simultaneously abut the workpiece from both sides, ensuring uniform force during clamping. The cutting seat 209f can be used to install cutting equipment, improving the convenience of using the device.

[0033] In use, the fixing bracket 205 on the surface of the card holder 203 works in conjunction with the abutment cylinder 206 to move the top block 207, which can fix some smaller sheet metal parts. The push cylinder 208b in the adjusting component 208 moves the moving seat 208d to place larger sheet metal parts on the mold 208f. The bottom of the sheet metal parts can be clamped by the moving seat 208d. When cutting some irregular sheet metal parts, the sheet metal parts are placed in the middle of the auxiliary cylinder 209d, and the protruding part of the sheet metal parts is placed in the abutment seat 209a. The auxiliary cylinder 209d is activated, and it moves the abutment block 209e to the position of the sheet metal parts to clamp them. The fixing cylinder 209b runs, which moves the push plate 209c. The push plate 209c works in conjunction with the abutment seat 209a to further reinforce the sheet metal parts. The cutting equipment is installed on the cutting seat 209f to ensure convenient cutting.

[0034] In summary, the omnidirectional wheels 102 of the moving mechanism 100 enable flexible movement, while the support frame 101 and the top-moving cylinder 104 ensure overall stability. The fixing mechanism 200 employs a multi-component design. The top block 207, driven by the abutment cylinder 206, can precisely fix small sheet metal parts. The push cylinder 208b in the adjusting component 208 drives the mold 208f and the limit rod 208c in linkage, which can not only stably clamp the bottom of large sheet metal parts, but also adapt to the dynamic adjustment of irregular workpieces. The symmetrically arranged clamping components 209, through the combined action of the double push cylinder 208b and the fixing cylinder 209b, enable the abutment block 209e and the push plate 209c to form a bidirectional clamping force, effectively dispersing cutting stress. Combined with the integrated design of the cutting seat 209f, it ensures uniform force during clamping and improves cutting positioning accuracy. The overall structure solves the problem of preventing deformation and accurately fixing sheet metal parts of different sizes and shapes in laser cutting through modular combination, thereby improving processing efficiency and product quality.
