[0033] See also Figure 1-Figure 6 , which is a schematic structural diagram of a workpiece tightening and assembling device provided in one embodiment of the utility model, the workpiece tightening and assembling device comprises a supporting mechanism 100, a transmission mechanism 400 provided on the supporting mechanism 100, a clamping mechanism 200 and a tightening mechanism 300, wherein:

[0034] In order to support the transmission mechanism 400, the clamping mechanism 200 and the tightening mechanism 300, the support mechanism 100 includes a frame 110 and a support frame 120 arranged at the center of the work surface 113 of the frame 110. The frame 110 is assembled by a prism frame 111 and a door panel 112. The prism frame 111 is overlapped to form a cubic frame, and door panels 112 are arranged around it. The top of the prism frame is a work surface 113 for supporting the transmission mechanism 400, the clamping mechanism 200 and the tightening mechanism 300. A bottom plate is arranged at the bottom. The door panel 112, the work surface 113 and the bottom plate enclose a storage space for storing goods. At the same time, door locks 114 and hinges 115 are installed on the front and rear door panels 112 to block the storage space and improve safety performance. At the same time, in order to facilitate movement, a number of casters 116 are also arranged at the bottom corners of the prism frame 111 to improve its applicability.

[0035] In order to fix the shell workpiece, a clamping mechanism 200 is symmetrically arranged on both sides of the support frame 120 at the center of the worktable 113. The clamping mechanism 200 includes a first mounting plate 210 arranged on the worktable 113 and clamping assemblies 220 symmetrically arranged at both ends of the first mounting plate 210 for clamping the shell workpiece. The first mounting plate 210 is also provided with a second guide rail 211 along its length direction, so that the clamping assembly 220 moves along the length direction of the second guide rail 211 to clamp the shell workpiece. At the same time, a shell workpiece fixture 230 is also provided at the center of the second guide rail 211 for accommodating the shell workpiece.

[0036] Furthermore, the clamping assembly 220 includes an adjusting member 221 disposed at the end of the first mounting plate 210 and a clamping member 222 coaxially connected to the adjusting member 221. A connecting block 223 is also disposed between the adjusting member 221 and the clamping member 222, so that the adjusting member 221 drives the clamping member 222 to move along the length direction of the second guide rail 211, thereby clamping the shell workpiece disposed in the shell workpiece fixture 230, and the clamping member 222 is disposed close to one end of the shell workpiece and is configured to conform to the shell workpiece, thereby reducing the wear between the two when the clamping member 222 clamps the shell workpiece. The adjusting member 221 in this embodiment can be an adjustable stroke cylinder, which can drive the clamping member 222 to move along the length direction of the second guide rail 211, and is used together with another symmetrically disposed clamping member 222 to clamp the shell workpiece.

[0037] In order to tighten the shell workpiece fixed on the first mounting plate 210, tightening mechanisms 300 are symmetrically arranged on both sides of the support frame 120. Any of the tightening mechanisms 300 is connected to the transmission mechanism 400 through the second mounting plate 340 and faces the shell workpiece. The tightening mechanism 300 includes a rotating member 310, a buffer member 320 arranged between the rotating member 310 and the second mounting plate 340, and a tightening member 330 arranged at one end of the second mounting plate 340 away from the buffer member 320. The buffer member 320 is fixed to the second mounting plate 340 through the fifth mounting plate 350, and one end of the rotating member 310 penetrates the buffer member 320 and is connected to the tightening member 330. A buffer 121 is arranged on the same side of the support member where the tightening member 330 is arranged. When the transmission mechanism 400 drives the tightening member 330 to move downward, one end of the buffer 121 can support the bottom of the second mounting plate 340 to reduce the impact force on the shell workpiece and avoid damage to it. In this embodiment, the buffer 121 can be an oil pressure buffer 121, which can be used to control the height of the second mounting plate 340 driven by the transmission mechanism 400. The tightening member 330 can be a servo motor, which can drive the tightening member 330 to rotate, so as to tighten the shell workpiece with a preset torque or number of turns. At the same time, in order to install an elastic member in the tightening member 330, the tightening member 330 can be retracted, thereby realizing the rotation and sinking of the thread. The buffer 320, the buffer 121 and the elastic member can effectively reduce the impact of the tightening member 330 on the shell workpiece, thereby ensuring that the shell workpiece is intact.

[0038] In order to drive the tightening member 330 to move in the up and down direction, a transmission mechanism 400 is provided on both sides of the interior of the support frame 120. The transmission mechanism 400 includes a third mounting plate 410 provided inside the support frame 120, a power member 420 and a transmission member 430 respectively provided on the third mounting plate 410, the transmission member 430 controls the transmission member 430 to move up and down, and a connecting plate provided at one end of the second mounting plate 340 is inserted into the support frame 120 to be connected to the transmission member 430, so that the power member 420 drives the second mounting plate 340 to move up and down through the transmission member 430, and then drives the tightening mechanism 300 provided on the second mounting plate 340 to move up and down.

[0039] Furthermore, the support frame 120 is provided with a fourth mounting plate 440 on both sides close to the tightening mechanism 300, and the fourth mounting plate 440 is provided with a first guide rail 450 arranged along the moving direction of the tightening mechanism 300, and the second mounting plate 340 is provided with a slider 460 adapted to the first guide rail 450. So that the second mounting plate 340 moves up and down along the fixed track on both sides of the support frame 120, thereby tightening the shell workpiece. And the second mounting plate 340 is also provided with reinforcing ribs 360 on both sides to enhance the strength of the tightening mechanism 300. The power member 420 in this embodiment is generally a cylinder, which can drive the second mounting plate 340 to move along the length direction of the first guide rail 450 through the transmission member 430.

[0040] It should be noted that the door panel 112 is also provided with a gas source triplet 500 for supplying gas to the device, and a conversion switch 600 for supplying power to the device. At the same time, a start switch 700 is also provided on both sides of the work surface 113 for controlling the start and stop of the device.

[0041] In summary, according to a workpiece tightening and assembly device provided by the utility model, the outer shell workpiece is fixed on the first mounting plate by using a clamping assembly, and then the transmission mechanism inside the support frame is used to drive the tightening mechanism arranged on both sides to move up and down, so as to tighten the outer shell workpiece with a preset torque.
