[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0030] Combination Figure 1-5 This embodiment discloses a sheet metal thin plate welding fixture mechanism, which aims to achieve flexible adaptation and precise positioning and clamping of sheet metal parts of different specifications through a series of innovative designs, thereby greatly improving welding quality and efficiency.
[0031] In this embodiment, the tooling mechanism specifically includes a support 100 with an aluminum alloy profile welded into a frame body, which serves as the basic support structure of the entire tooling mechanism. It is made of sturdy and durable materials to ensure sufficient stability and load-bearing capacity.
[0032] The support frame 100 is equipped with casters 120 at the bottom, which facilitates movement and position adjustment within the workshop, as well as appropriate adjustment of the position of the support frame 100 during the welding process, reducing the movement of workers and thus reducing labor intensity.
[0033] The bracket 100 has a plate at its top that allows for height adjustment. The bracket 100 also has several vertically arranged telescopic rods 110, and the plate is horizontally fixed to the top of the telescopic rods 110. By adjusting the height of the telescopic rods 110, the installation height of the plate and the upper platform 200 can be flexibly adjusted to accommodate the height and working needs of different operators.
[0034] A platform 200 is provided on the top of the plate, which is a water platform 200 surface structure and serves as the main welding workbench for placing the sheet metal parts to be welded. A pad 210 is provided between the platform 200 and the plate. The pad 210 is made of rubber and its function is to raise the platform 200 and act as a buffer and shock absorption structure, so that the platform 200 has a certain degree of elastic support. This helps to improve the tooling safety of the sheet metal workpiece a and avoid damage to the sheet metal workpiece a from excessive rigid collisions.
[0035] The top of the platform 200 is provided with two reference blocks 300 that are spaced apart from each other. The installation position of the reference blocks 300 is adapted to the outline of the sheet metal workpiece a to be processed.
[0036] Furthermore, a support block 400 is provided at intervals on one side of the reference block 300. The reference block 300 and the support block 400 form a tooling gap for snapping the sheet metal workpiece a, ensuring the precise positioning of the sheet metal workpiece during the welding process.
[0037] A holding member 500 is provided on one side of the support block 400. The holding member 500 has a pressure rod 560 that can press down and abut against the top of the support block 400. The pressure rod 560 and the support block 400 form a sheet metal workpiece holding structure. By adjusting the position and force of the pressure rod 560, stable clamping of sheet metal parts of different specifications can be achieved.
[0038] Specifically, such as Figure 3 As shown, the support block 400 includes a first base 410 connected to the platform 200. A support platform 420 is detachably connected to the top of the first base 410, and the pressure rod 560 can press down and abut against the top end face of the support platform 420. This structure further improves the flexibility and adaptability of the tooling mechanism, allowing the specifications of the support platform 420 to be changed according to actual processing needs, and the height of the components to be adjusted, forming a longitudinal adjustment structure.
[0039] The holding member 500 includes a second base 510 connected to the platform 200. A mounting platform 520 is detachably connected to the top of the second base 510. A frame 530 is mounted on the top of the mounting platform 520. A handle 540 and a holding arm 550 are hinged to the top of the frame 530. A pressure rod 560 is mounted on the holding arm 550. After the handle 540 swings in a threshold direction, it can press down and limit the holding arm 550 and the pressure rod 560. The bottom of the pressure rod 560 and the top of the support platform 420 form a longitudinal clamping structure for the sheet metal workpiece a. The function of the second base 510 is the same as that of the first base 410. It should be noted that the holding member 500 is prior art, and its specific structure and working principle will not be described in detail here. Those skilled in the art can select and implement it from the prior art according to actual operating conditions.
[0040] To improve clamping stability and protect the sheet metal surface from damage, the bottom of the pressure bar 560 is equipped with a pressure block made of elastic material.
[0041] The support block 400 is provided with a limiting block 600 on its outer side. The limiting block 600 is connected to a clamping cylinder 700, which can drive the limiting block 600 to form a lateral limiting structure for the sheet metal workpiece a. This design ensures the lateral stability of the sheet metal workpiece during the welding process and prevents it from shifting due to external forces.
[0042] Working Principle: When using the sheet metal welding fixture mechanism of this utility model, the operator first adjusts the height of the support 100, the position of the pad 210 of the platform 200, the layout of the reference block 300 and the support block 400, and the positions of the clamping component 500 and the limiting block 600 according to the specifications and shape of the sheet metal part to be welded. Then, the sheet metal part is placed on the platform 200, and the clamping component 500 and the limiting block 600 achieve precise clamping and positioning of the sheet metal part. During the welding process, the operator can adjust the force and position of the clamping component 500 as needed to ensure the stability and accuracy of the sheet metal part during the welding process. The sheet metal welding fixture mechanism in this embodiment, through a series of innovative designs and technical improvements, achieves flexible adaptation and precise positioning and clamping of sheet metal parts of different specifications, greatly improving welding quality and efficiency. This fixture mechanism not only has broad application prospects and market value, but also provides new ideas and methods for technological progress and industrial upgrading in the sheet metal processing industry.
[0043] In other embodiments, a lateral position adjustment structure is provided between the first base 410 and the second base 510 and the platform 200, such as a combination structure of strip holes and bolts, so that the installation position of the support block 400 and the pressure member 500 is more flexible and changeable. This design allows the operator to adjust the position of the support block 400 and the pressure member 500 according to actual needs to meet the welding requirements of different sheet metal parts.
[0044] In another embodiment, such as Figure 5 As shown, the support platform 420 has an extension platform 430 that is wider at the top and narrower at the bottom, and a gasket 440 is provided on the top end face of the extension platform 430. This structure is used to increase the contact area with the sheet metal part and reduce the pressure concentration during clamping.
[0045] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
