Description

Technical Field

[0001] The present invention belongs to the technical field of prototype part manufacturing tooling, and relates to a laser cutting bracket with adjustable clearance. Background Art

[0002] When laser cutting large-sized sheet materials, if the suspended area of the sheet material is too large, the sheet material will collapse downward at the non-contact part with the bracket due to gravity, resulting in dimensional deviation and shape error in the blanking. When laser cutting sheet materials with a small width and special-shaped shapes such as the rear triangle of an automobile, since the edge of the sheet material is in a non-contact state with the laser cutting bracket, there will be phenomena such as dimensional deviation, shape error, and serious burrs in the sheet material. If a copper rod type laser cutting bracket is used, the support rod on the bracket will be damaged due to laser cutting, resulting in the bracket being unusable and needing to be replaced. The repair cost of the support rod is high and a large inventory is required. For a sawtooth type laser cutting bracket, the shape of its support frame is sawtooth-shaped and very sharp. When picking and placing products, it is easy to scratch the surface of the products, resulting in an increase in the product rejection rate. Summary of the Invention

[0003] The technical problem to be solved by the present invention is, in view of the current situation of the prior art, to provide a laser cutting bracket with adjustable clearance, which can improve the qualification rate of blanking size and shape, accurate positioning, reduce burrs of semi-finished products, has a low loss rate of the laser cutting bracket, will not scratch the surface of the products when picking and placing products, and reduces the product rejection rate.

[0004] The technical solution adopted by the present invention to solve the above technical problem is: a laser cutting bracket with adjustable clearance, characterized in that it includes a bottom plate, and four side supports are arranged on the peripheral surfaces of the bottom plate. The four side supports form a support space. In the longitudinal direction of the support space, multiple groups of directional longitudinal support frames and multiple groups of adjustable longitudinal support frames are arranged.

The multiple groups of directional longitudinal support frames, adjustable longitudinal support frames, multiple groups of directional transverse support frames, and adjustable transverse support frames are arranged in a cross manner to form a support plane. On both sides of the adjustable longitudinal support frame, a longitudinal adjustment mechanism for driving the adjustable longitudinal support frame to move up and down is connected. On both sides of the adjustable transverse support frame, a transverse adjustment mechanism for driving the adjustable transverse support frame to move up and down is connected.

[0005] In the above-mentioned laser cutting bracket with adjustable clearance, the four side supports are two transverse side supports and two longitudinal side supports. Among them, the first shallow groove and the first deep groove are spaced apart on the transverse side support, and the second shallow groove and the second deep groove are spaced apart on the longitudinal side support.

[0006] In the above-mentioned laser cutting bracket with adjustable gap, each group of adjusting longitudinal support frames includes a first serrated part and a first side connection part. The first side connection part has a first connection fork, and the first connection fork is connected to the longitudinal adjustment mechanism. Each group of directional longitudinal support frames includes a second serrated part and a second side fixing part. The bottom of the directional longitudinal support frame is clamped at the first shallow groove on the transverse side support frame, and the first side connection part is clamped at the first deep groove and moves up and down.

[0007] In the above-mentioned laser cutting bracket with adjustable gap, the longitudinal adjustment mechanism includes a longitudinal driving rod, two longitudinal guide seats, and a longitudinal driving cylinder. The longitudinal guide seats are located on both sides of the longitudinal driving cylinder. Both sides of the longitudinal driving rod are sleeved on the longitudinal guide seats. The longitudinal driving cylinder is located in the middle and its output end is connected to the longitudinal driving rod. The longitudinal driving rod is provided with a first fixing port that cooperates with the first connection fork.

[0008] In the above-mentioned laser cutting bracket with adjustable gap, each group of adjusting transverse support frames includes a third serrated part and a third side connection part.

[0009] In the above-mentioned laser cutting bracket with adjustable gap, the transverse adjustment mechanism includes a transverse driving rod, two transverse guide seats, and a transverse driving cylinder. The transverse guide seats are located on both sides of the transverse driving cylinder. Both sides of the transverse driving rod are sleeved on the transverse guide seats. The transverse driving cylinder is located in the middle and its output end is connected to the transverse driving rod. The transverse driving rod is provided with a second fixing port that cooperates with the third connection fork.

[0010] In the above-mentioned laser cutting bracket with adjustable gap, the first serrated part, the second serrated part, the third serrated part, and the fourth serrated part all have a fillet with an R of 0.5 mm.

[0011] Compared with the prior art, the advantages of the present invention are that the distance between the support frames can be adjusted, and the minimum can reach 10 mm * 10 mm, making the semi-finished products of laser cutting have qualified sizes, accurate shapes, and reduced burrs on the semi-finished products; half of the support frames can move vertically up and down.

[0020] As Figure 1As shown in the figure, the laser cutting bracket with adjustable clearance includes a bottom plate 100. Four side brackets are arranged on the peripheral surface of the bottom plate 100. The four side brackets form a support space. The four side brackets are two transverse side brackets 200 and two longitudinal side brackets 300. The transverse side brackets 200 and the longitudinal side brackets 300 are welded to the bottom plate 100. The welded connections between the transverse side brackets 200 and the longitudinal side brackets 300 are fixed by tenon and mortise structures and then welded, which greatly improves the dimensional accuracy after welding. First shallow grooves 201 and first deep grooves 202 are spacedly arranged on the transverse side brackets 200. Second shallow grooves 301 and second deep grooves 302 are spacedly arranged on the longitudinal side brackets 300.

[0021] Multiple groups of directional longitudinal support frames 400 and multiple groups of adjustable longitudinal support frames 500 are arranged in the longitudinal direction of the support space. Multiple groups of directional transverse support frames 600 and multiple groups of adjustable transverse support frames 700 are arranged in the transverse direction of the support space. In this embodiment, there are ten groups of directional longitudinal support frames 400, ten groups of adjustable longitudinal support frames 500, ten groups of directional transverse support frames 600, and ten groups of adjustable transverse support frames 700. Here, the number of support frames can be appropriately increased or decreased to adjust the distance between the support frames. The minimum distance can reach 10mm * 10mm. Taking the external dimension of 1200mm * 1200mm and the fixed distance between the support frames of 120mm * 120mm, which can be adjusted to a distance of 60mm * 60mm as an example, ten groups of directional longitudinal support frames 400, adjustable longitudinal support frames 500, ten groups of directional transverse support frames 600, and adjustable transverse support frames 700 are arranged in a crosswise manner to form a support plane D. Longitudinal adjustment mechanisms 800 for driving the adjustable longitudinal support frames 500 to move up and down are connected to both sides of the adjustable longitudinal support frames 500. Transverse adjustment mechanisms 900 for driving the adjustable transverse support frames 700 to move up and down are connected to both sides of the adjustable transverse support frames 700. Here, by using the longitudinal adjustment mechanisms 800 and the transverse adjustment mechanisms 900, the adjustable longitudinal support frames 500 and the adjustable transverse support frames 700 can be extended or retracted, so as to realize the adjustment of the minimum distance between the support frames.

[0022] Specifically, as Figure 2 and Figure 3As shown, for optimization, each set of adjustable longitudinal support frames 500 includes a first serrated portion 501 and a first side connection portion 502. The first side connection portion 502 has a first connection fork 503, and the first connection fork 503 is connected to the longitudinal adjustment mechanism 800. Each set of directional longitudinal support frames 400 includes a second serrated portion 401 and a second side fixing portion 402. The bottom of the directional longitudinal support frame 400 is clamped at the first shallow groove 201 on the transverse side support frame 200, and the first side connection portion 502 moves up and down while being clamped at the first deep groove 202. The longitudinal adjustment mechanism 800 includes a longitudinal driving rod 801, two longitudinal guide seats 802, and a longitudinal driving cylinder 803. The longitudinal guide seats 802 are located on both sides of the longitudinal driving cylinder 803. Both sides of the longitudinal driving rod 801 are sleeved on the longitudinal guide seats 802. The longitudinal driving cylinder 803 is located in the middle and its output end is connected to the longitudinal driving rod 801. A first fixing port 804 that cooperates with the first connection fork 503 is provided on the longitudinal driving rod 801. When it is necessary to control the extension or retraction of the adjustable longitudinal support frame 500, the longitudinal driving cylinder 803 can drive the longitudinal driving rod 801 to move. The use of the longitudinal guide seats 802 for guiding can ensure the movement stability. Since the first connection fork 503 is connected to the first fixing port 804, the movement of the longitudinal driving rod 801 will drive the entire adjustable longitudinal support frame 500 to move up and down, thereby controlling the extension or retraction of the ten sets of adjustable longitudinal support frames 500.

[0023] As Figure 4 and Figure 5As shown in the figure, as an optimization, each set of adjustable horizontal support frames 700 includes a third serrated portion 701 and a third side connection portion 702. The third side connection portion 702 is provided with a third connection fork 703, and the third connection fork 703 is connected to the horizontal adjustment mechanism 900. Each set of directional horizontal support frames 600 includes a fourth serrated portion 601 and a fourth side fixing portion 602. The bottom of the directional horizontal support frame 600 is clamped at the second shallow groove 301 on the longitudinal side support frame 300, and the third side connection portion 702 is clamped at the second deep groove 302 and moves up and down. The horizontal adjustment mechanism 900 includes a horizontal driving rod 901, two horizontal guide seats 902, and a horizontal driving cylinder 903. The horizontal guide seats 902 are located on both sides of the horizontal driving cylinder 903. Both sides of the horizontal driving rod 901 are sleeved on the horizontal guide seats 902. The horizontal driving cylinder 903 is located in the middle and its output end is connected to the horizontal driving rod 901. The horizontal driving rod 901 is provided with a second fixing port 904 that cooperates with the third connection fork 703. Similarly, the entire adjustable horizontal support frame 700 will be driven by the horizontal driving rod 901 to move up and down, so as to control the extension or retraction of the ten sets of adjustable horizontal support frames 700. In order to eliminate the phenomenon of the support frame scratching the product, the first serrated portion 501, the second serrated portion 401, the third serrated portion 701, and the fourth serrated portion 601 all have rounded corners with a radius of R0.5mm. Here, after the support frame is worn, the support frame can be cut by a laser cutting machine, and then the height requirement of the laser-cut support frame can be met by padding gaskets under the cylinder bracket. The wear rate of the support frame is low.

[0024] This patent can be realized in three states. When the horizontal driving cylinder 903 and the vertical driving cylinder 803 are fully extended, the minimum distance between the support frames is 60mm * 60mm. When the horizontal driving cylinder 903 is extended and the vertical driving cylinder 803 is retracted, the minimum distance between the support frames is 120mm * 60mm. When the horizontal driving cylinder 903 and the vertical driving cylinder 803 are all retracted, the minimum distance between the support frames is 120mm * 120mm.

[0025] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the scope defined by the spirit of the present invention.
