[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] like Figure 1 As shown, a workpiece angle fixing device includes two sets of angle fixing components 2 and a tray 3. The two sets of angle fixing components 2 are parallel to each other and axially symmetrical. The tray 3 is set at a fixed position or on a transmission line and is located on the axis between the two sets of angle fixing components 2. The workpiece 1 is placed on the tray 3. The workpiece 1 has two notches 11 symmetrically arranged on its periphery, and each notch 11 faces a corresponding angle fixing component 2. The two sets of angle fixing components 2 can be inserted into the notches 11 of the workpiece 1 and clamp the workpiece 1.

[0030] like Figure 2 As shown, each angle fixing assembly 2 includes a support frame 21 and an angle fixing unit 22. The support frame 21 includes a base plate 211, a U-shaped bracket 212 and a support plate 213. The closed end of the U-shaped bracket 212 is fixedly connected to the base plate 211.

The first metal plate 2211 has a second circular hole 2212 and two third circular holes 2213. The movable end of the telescopic cylinder 223 is slidably connected to the second circular hole 2212. The movable end of the telescopic cylinder 223 is fixedly connected to the clamping module 222. The telescopic cylinder 223 is fixed to the first metal plate 2211. The telescopic cylinder 223 is prior art, and its model number is ACQS-50x5050.

[0033] like Figure 4 As shown, the lifting module 221 also includes two pins 2215, each pin 2215 is correspondingly set with the pneumatic flexible positioner 214, and each pin 2215 is mounted on the first metal plate 2211, with the pin 2215 slidably connected in the corresponding pneumatic flexible positioner 214. During installation, hold the two handles 2214 of the lifting module 221 with both hands, slide the pin 2215 into the pneumatic flexible positioner 214, and place the angle fixing unit 22 on the U-shaped bracket 212. The inductive proximity sensor 215 will detect the position of the angle fixing unit 22. When the position is accurate, the inductive proximity sensor 215 will send a signal to the controller. The controller will control the pneumatic flexible positioner 214 to increase atmospheric pressure and clamp the pin 2215. The detachable angle fixing unit 22 can not only quickly troubleshoot and repair, but also make it easy to replace.

[0034] like Figure 5As shown, the clamping module 222 includes a second metal plate 2221, two metal rods 2222, and a C-shaped metal plate 2223. The inner side of the second metal plate 2221 is fixedly connected to the movable end of the telescopic cylinder 223. The periphery of each metal rod 2222 is slidably connected to a third circular hole 2213, and the two metal rods 2222 are fixedly connected to the inner side of the second metal plate 2221.

The sliding groove is an elliptical through groove, and a pin is slidably connected in each sliding groove. One end of each pin is threaded to the second metal plate 2221, and the clamping plate 2224 can slide vertically along the rectangular groove 2225. Adjusting the position of the clamping plate 2224 up and down according to the size of the workpiece allows for the adaptation of workpieces 1 with similar sizes without changing the angle fixing unit 22, reducing production line downtime caused by frequent unit changes and improving work efficiency.

[0035] like Figure 4 and Figure 5 As shown, the second metal plate 2221 is also provided with two fourth circular holes 2226. A support rod 2227 is slidably connected in each fourth circular hole 2226. The two support rods 2227 are arranged parallel to each other. One end of each support rod 2227 is fixedly connected to the C-shaped metal plate 2223. A spring is sleeved around the periphery of each support rod 2227. One end of the spring abuts against the second metal plate 2221, and the other end of the spring abuts against the C-shaped metal plate 2223. When the controller is turned on, when the tray 3 moves the workpiece between the two sets of angle fixing components 22, the controller will control the telescopic cylinder 223 to extend. The telescopic cylinder 223 will push the clamping modules 222 on both sides to move towards the workpiece 1. The two C-shaped metal plates 2223 will first pre-clamp the workpiece 1. After fixing the approximate position of the workpiece, the clamping plates 2224 on the clamping modules 222 will be embedded in the notches 11 on both sides of the workpiece 1 to complete the angle fixing of the workpiece 1. This device allows for pre-clamping of the workpiece before angle fixation, preventing dynamic disturbances and ensuring workpiece stability, thereby precisely fixing the workpiece's angle.

[0036] like Figure 6 As shown, the tray 3 includes a base 31 and a circular frame 32. The circular frame 32 is fixedly connected to the base 31, and the lower end of the workpiece 1 can be inserted into the upper inner ring of the circular frame 32.

[0038] Turn on the controller, hold the two handles 2214 of the lifting module 221 with both hands, slide the pin 2215 into the pneumatic flexible positioner 214, and place the angle fixing unit 22 on the U-shaped bracket 212. The inductive proximity sensor 215 will detect the position of the angle fixing unit 22. When the position is accurate, the inductive proximity sensor 215 will send a signal to the controller. The controller will control the pneumatic flexible positioner 214 to increase the atmospheric pressure and clamp the pin 2215. Adjust the position of the clamping plate 2224 up and down according to the size of the workpiece. After the position is accurately adjusted, connect the pin threaded to the second metal plate 2221 to complete the equipment installation. When the pallet 3 moves the workpiece between the two sets of angle fixing components 22, the controller will control the telescopic cylinder 223 to extend. The telescopic cylinder 223 will push the clamping modules 222 on both sides to move towards the workpiece 1. The two C-shaped metal plates 2223 will first pre-clamp the workpiece 1 and fix the approximate position of the workpiece. Then, the clamping plates 2224 on the clamping module 222 will be embedded in the notches 11 on both sides of the workpiece 1 to complete the angle fixing of the workpiece 1.

The power supply is also common knowledge in the art.
