[0002] During the production process of sheet metal parts, positioning fixtures are needed to fix the spatial position of the sheet metal parts, so as to ensure that the sheet metal parts are in the correct processing position during processing to prevent the sheet metal parts from being displaced.

[0003] There are many kinds of existing sheet metal clamps, but most of them have complex structures and require multiple mechanisms for clamping, which has low clamping efficiency. During the processing, sheet metal parts are mostly regular-shaped plates, so they only need to be simply fixed when clamping. There is an urgent need for a clamp with a simple structure and quick clamping.

[0004] After searching, it was found that the Chinese utility model patent with patent number "CN202322530072.4" discloses a clamp for cutting sheet metal parts, which includes: a base; a load-bearing block is installed and fixed on the upper end of the base; an L-frame is installed on the upper end of the load-bearing block, and the lower end of one side of the L-frame is fixed to the base by bolts, and buffer pads are provided on the left and right sides of the upper end of the load-bearing block, and a cover plate is installed on the buffer pad; a clamping groove is formed between the middle lower end of the cover plate and the middle upper end of the base, a clamping assembly is installed at the lower end of the cover plate, and an adjustment assembly is provided at the upper end of the cover plate; at the same time, both sides of the cover plate are installed and fixed at the position of the buffer pad by locking caps, and a cutting cavity is formed at the upper end of the base at a position on one side of the cover plate; the clamp for cutting sheet metal parts places one end of the sheet metal to be processed in the clamping groove for position fixation, and at the same time there is a large space for cutting cavity, so there is no need to consider designing a cutting groove on the base.

[0028] As described in the background art, the existing clamps have a complex structure, the clamping steps are complicated, and it is not convenient to make timely adjustments according to the size of the sheet metal parts.

[0029] For the reasons stated above, please refer to the attached Figure 1 ~Attached Figure 3The utility model provides a sheet metal processing fixture, comprising a support base 1, on both sides of the top of which are arranged support plates 6 which are oppositely distributed and can keep sliding on the support base 1;

[0030] The transmission mechanism is rotatably arranged at the center of the support base 1 to drive the support plates 6 on both sides to move away from or closer to each other;

[0031] A clamping plate 8 is movably arranged on the supporting plate 6;

[0032] The pressure rod 9 is rotatably disposed on the clamping plate 8 and presses the parts between the two clamping plates 8 through the telescopic mechanism 11.

[0033] Specifically, a slide rail 2 is disposed on the support base 1 , and a slider 7 matched with the slide rail 2 is disposed at the bottom of the support plate 6 .

[0034] Specifically, the transmission mechanism includes a rotating rod 3, which is rotatably arranged at the center of the supporting base 1 and has a transmission wheel 10 at one end. The transmission wheel 10 is driven by an external driving device to maintain forward and reverse rotation. A hinge plate 4 is arranged at the other end of the rotating rod 3. The end of the rotating rod 3 is fixed at the center of the hinge plate 4. Connecting rods 5 are respectively arranged on the outer opposite ends of the hinge plate 4. The two ends of the connecting rod 5 are respectively hinged on the hinge plate 4 and the support plate 6.

[0035] By adopting the above technical features, the rotating rod and the connecting rods on both sides of the hinged plate can be arranged to facilitate the rotation of the rotating rod to drive the support plates on both sides to move closer or farther away, thereby facilitating the rapid clamping of the sheet metal parts.

[0036] Specifically, the support plate 6 is an L-shaped plate, one end of which is a horizontal end and a slider 7 is arranged at the bottom of the horizontal end, the other end of the support plate 6 is a vertical end and the vertical end is kept on the outer end of the support base 1, and a dovetail groove is opened along the length direction on the horizontal end of the support plate 6, and the bottom end of the clamping plate 8 is inserted into the dovetail groove and moves linearly in the dovetail groove.

[0037] By adopting the above technical features, a dovetail groove is provided on the support plate to facilitate the installation of the clamping plate, and at the same time, it can ensure that the clamping plate moves linearly on the support plate, which is convenient for adjustment according to different sizes of sheet metal parts, thereby achieving clamping.

[0038] Specifically, an adjusting rod 12 passes through the vertical end of the support plate 6 , and the adjusting rod 12 is threadedly connected to the support plate 6 and keeps the end thereof rotatably connected to the clamping plate 8 .

[0039] By adopting the above technical features, the adjustment rod is provided to facilitate the adjustment and fixation of the clamping plate, thereby adjusting the position of the clamping plate on the support plate to facilitate the rapid clamping of sheet metal parts of different sizes.

[0040] Specifically, a vertical strip hole is opened on the splint 8, a horizontal rod body is arranged in the strip hole, the pressure rod 9 is inserted into the strip hole and rotatably installed on the outer side of the rod body, and a pressure head is arranged at the end of the pressure rod 9 away from the vertical end of the support plate 6. The other end of the pressure rod 9 drives the pressure rod 9 to rotate around the rod body through the telescopic mechanism 11.

[0041] By adopting the above technical features, the pressure rod and its connection form are provided to facilitate the compression of the sheet metal parts between the clamping plates, thereby preventing the sheet metal parts from moving upward during processing.

[0046] When the processing fixture is in use, the position of the clamping plate 8 on the support plate 6 is first adjusted according to the size of the pre-clamped sheet metal by rotating the adjusting rod 12, and then the sheet metal is placed on the two support plates 6, and the transmission wheel 10 is driven to rotate by an external driving device (such as a driving motor and a gear transmission mechanism), thereby driving the rotating rod 3 and the hinge plate 4 to rotate. Since the outer side of the hinge plate 4 is hinged with a connecting rod 5, the connecting rod 5 will be driven to move to one side, thereby driving the support plates 6 on both sides to gather together. In this process, the clamping plate 8 on the support plate 6 can clamp the sheet metal, and then the telescopic mechanism 11 is retracted, and the pressure rod 9 is driven to rotate through the ring body 13. The end of the pressure rod 9 close to the ring body 13 flips upward with the ring body 13, and the other end flips downward, thereby realizing the compression of the sheet metal, thereby realizing the rapid clamping of the sheet metal, which is convenient for processing.
