[0028] Embodiment

[0029] Refer to Figures 1 - 4, the present utility model provides a technical solution: a fixture for workpiece assembly, including a support frame 1 and a clamping mechanism 3, and a positioning frame 2 is fixedly installed on the support frame 1. The clamping mechanism 3 includes a positioning plate 31, the positioning plate 31 is fixedly installed on the positioning frame 2, a rotating disk 311 is rotatably connected to the outer surface of the positioning plate 31, a driving motor 32 is fixedly installed at the bottom of the positioning plate 31, the output end of the driving motor 32 is fixedly connected to a transmission shaft 321, one end of the transmission shaft 321 is fixedly connected to the rotating disk 311, a cylindrical rod 33 is fixedly installed on the upper surface of the positioning plate 31, a bearing plate 331 is installed at the top of the cylindrical rod 33, and a first electric telescopic rod 332 is installed on the bearing plate 331, and a clamping plate 333 is fixedly installed at the telescopic end of the first electric telescopic rod 332.

[0030] In a preferred embodiment, a reinforcing rib 4 is fixedly installed on the support frame 1, and a connecting plate 5 is also fixedly installed outside the upper end of the support frame 1. To enable the stable use of the device, a reinforcing rib 4 is installed on the support frame 1. The reinforcing rib 4 is provided in several numbers and is respectively arranged on the left and right sides of the support frame 1 to improve the use stability of the device.

[0031] In a preferred embodiment, a fixing plate 6 is fixedly installed on the upper surface of the bearing plate 331, and a sliding groove 7 is opened on the upper surface of the bearing plate 331. A slider is arranged inside the sliding groove 7, and one side surface of the slider is fixedly connected to the clamping plate 333. The workpiece is placed on the upper surface of the bearing plate 331, and the workpiece is clamped by the clamping plate 333. Therefore, a sliding groove 7 is provided on the bearing plate 331, and the clamping plate 333 is fixedly connected to the slider, so that the clamping plate 333 can stably move on the bearing plate 331, facilitating the clamping and assembly of the workpiece.

[0032] In a preferred embodiment, an airbag 8 is installed at the inner side of the support frame 1, and an extrusion rod 9 is sleeved outside the transmission shaft 321. The airbag 8 is extruded by the extrusion rod 9 to generate gas for dissipating heat from the driving motor 32. The driving motor 32 will generate a certain amount of heat during use. Although the driving motor 32 is arranged outside the device and can also dissipate heat, to improve the heat dissipation effect, an airbag 8 is installed at the inner side of the support frame 1. The extrusion rod 9 is controlled to rotate by the driving motor 32, and the extrusion rod 9 will extrude the inside of the airbag 8, squeezing out the gas inside the airbag 8 and blowing air to the driving motor 32, accelerating the flow of the hot air of the driving motor 32 itself and facilitating the heat dissipation of the driving motor 32.

[0033] When one end of the workpiece is equipped with a gas workpiece, the weight of one end of the workpiece will increase, which easily causes the workpiece to tilt. To solve this problem, a correction mechanism 10 is installed on the connecting plate 5. The correction mechanism 10 includes a second electric telescopic rod 101, a pushing plate 102 and a pressure sensor 103. The second electric telescopic rod 101 is fixedly installed at the bottom of the connecting plate 5. The telescopic end of the second electric telescopic rod 101 penetrates through the inside of the connecting plate 5 and is fixedly connected to the pushing plate 102. A rotating frame 11 is installed on the outer side of the bearing plate 331, and a horizontal rod 12 is rotatably installed at the inner position of the rotating frame 11. A hollow chamber 13 is also fixedly installed on the upper surface of the connecting plate 5. A support plate 14 is slidably connected inside the hollow chamber 13. A spring 15 is installed at the bottom of the support plate 14. One end of the spring 15 is fixedly connected to the inner bottom of the hollow chamber 13. A pressure sensor 103 is also fixedly installed inside the hollow chamber 13. The pressure sensor 103 is electrically connected to a PLC controller 16, and the PLC controller 16 is electrically connected to the second electric telescopic rod 101.

[0034] During actual use, when one end of the workpiece tilts downward, it will squeeze the horizontal rod 12. One end of the horizontal rod 12 will also tilt downward and move to squeeze the support plate 14, pressing the support plate 14 downward. As one end of the workpiece continues to tilt, it will drive the horizontal rod 12 to continue to rotate downward until the support plate 14 is squeezed downward and presses the pressure sensor 103. When the pressure sensor 103 detects the presence of pressure, it will control the second electric telescopic rod 101 to work through the PLC controller 16, and control the pushing plate 102 to move upward through the telescopic end of the second electric telescopic rod 101, thereby restoring the tilted end of the workpiece to normal, making the workpiece in a horizontal state, preventing the workpiece from falling off the bearing plate 331, and ensuring the normal assembly of the workpiece.

[0035] Specifically, the working process or working principle of a fixture for workpiece assembly is as follows: In actual operation, it will be found that workpiece assembly is not only carried out at one end. Especially for sheet metal assembled at both ends, the other end also needs to be assembled. For the above-mentioned fixture, this means that after one end of the workpiece is assembled, the workpiece needs to be disassembled and reinstalled and clamped so that the workpiece can be assembled again. Such an operation will waste time and reduce work efficiency. Therefore, this device is designed to solve this problem.

[0036] This device not only clamps the workpiece to enable stable assembly, but also can change the position of the workpiece for assembly at different positions of the workpiece, meeting the usage requirements, saving time, and improving work efficiency. The specific operation is as follows: Connect to an external power supply, place the workpiece on the upper surface of the load-bearing plate 331, then turn on the first electric telescopic rod 332. The telescopic end of the first electric telescopic rod 332 pushes the clamping plate 333 to move. The clamping plate 333 pushes the workpiece to the position on one side of the fixed plate 6, so that one side of the workpiece abuts against the fixed plate 6, and the other side is squeezed by the clamping plate 333, thus stably clamping the workpiece on the load-bearing plate 331. Then, other workpieces from the outside can be assembled on the workpiece on the load-bearing plate 331.

[0037] If other workpieces need to be assembled at both ends of the workpiece respectively, after the assembly of one end is completed, the load-bearing plate 331 can be rotated by the driving motor 32 to drive the workpiece to rotate and change the assembly position of the workpiece, without disassembling the workpiece, reinstalling it in the reverse direction and then assembling it, saving time and improving work efficiency.

[0038] During actual use, when other workpieces are assembled at one end of the workpiece, one end of the workpiece is likely to tilt downward. During the downward tilt, the horizontal rod 12 will also tilt downward. A torsion spring is installed at the position of the horizontal rod 12 in this device, so that the horizontal rod 12 will automatically return to its initial position after the pressure is removed. When one end of the horizontal rod 12 moves downward and tilts, it will squeeze the support plate 14 and press the support plate 14 downward. As one end of the workpiece continues to tilt, it will drive the horizontal rod 12 to continue to rotate downward until the support plate 14 is squeezed downward and presses the pressure sensor 103. When the pressure sensor 103 detects the presence of pressure, it will control the second electric telescopic rod 101 to work through the PLC controller 16, and the telescopic end of the second electric telescopic rod 101 will control the push plate 102 to move upward, thereby restoring the tilted end of the workpiece to normal and making the workpiece in a horizontal state, preventing the workpiece from falling off the load-bearing plate 331 and ensuring the normal assembly of the workpiece.

[0039] An airbag 8 is installed at the inner side of the upper end of the support frame 1 of this device. While the driving motor 32 controls the transmission shaft 321 to rotate, it will drive the extrusion rod 9 to squeeze the airbag 8. After the airbag 8 is squeezed, it will eject gas. The air outlet hole of the airbag 8 corresponds to the position of the driving motor 32, so as to blow air and dissipate heat for the driving motor 32, extending the service life of the driving motor 32 and meeting the usage requirements.

[0040] A return spring is installed inside the airbag 8 of this device. Through the return spring, the squeezed airbag 8 can automatically return to its initial state. This airbag 8 is a prior art and does not need to be described in detail here. An air inlet pipe and an air outlet pipe are installed on the airbag 8, and one-way valves are installed on the air inlet pipe and the air outlet pipe respectively. The air outlet pipe is facing the driving motor 32 to dissipate heat for the driving motor 32.

[0041] It should be noted that the drive motor 32, the first electric telescopic rod 332, the second electric telescopic rod 101, the pressure sensor 103, and the PLC controller 16 are devices or equipment existing in the prior art, or devices or equipment that can be realized by the prior art. Their power supply, specific composition, and principle are clear to those skilled in the art, so they will not be elaborated in detail.
