Therefore, a lifting and rotating positioning device is proposed, which can lift, rotate and position the workpiece pallet, realize the reversal of the workpiece pallet, and improve the accuracy of workpiece processing, assembly or testing.

[0028] When in use, the lifting cylinder 108 pushes the rotating component 2 up and down, and the rotating cylinder 210 drives the rotating plate 206 to rotate. When the rotating component 2 is lifted, the two positioning pins 207 are inserted into the positioning holes 302 at the bottom of the tray 3, and the rotating component 2 drives the tray 3 to rotate when it rotates.

[0029] For example, Figure 2 As shown, the utility model also includes that the two ends of one side of the lifting cylinder 108 are connected to the air pipe joints 107 through threaded grooves, and the ends of the lifting cylinder 108 located on both sides of the air pipe joints 107 are embedded with magnetic switches 106.

[0030] When in use, the opening of the air pipe joint 107 facilitates the compressed air to enter the lifting cylinder 108, and the magnetic switch 106 is used to detect the position of the piston of the lifting cylinder 108.

[0031] For example, Figure 3 As shown, the utility model also includes that the rotating cylinder mounting plate 214 is fixed to the top of the piston rod joint 104 by a gasket 103 and a hexagon socket semicircular head screw 102, and the first stopper 205 and the second stopper 209 are fixed to the two ends of the bottom of the rotating plate 206 by bolts.

[0032] When in use, the first stopper 205 and the second stopper 209 are provided to limit the rotation of the rotating plate 206 .

[0033] For example, Figure 3 As shown, the utility model also includes that the first magnetic switch 212 and the second magnetic switch 213 are respectively embedded at two ends of one side of the rotary cylinder 210, and the first air port 201 and the second air port 202 are respectively opened at two ends of the rotary cylinder 210.

[0034] When in use, the first magnetic switch 212 is used to detect the position of the piston of the rotary cylinder 210 , and the first air port 201 and the second air port 202 facilitate the compressed air to enter the rotary cylinder 210 .

[0035] For example, Figure 3 As shown, the utility model also includes that a stopper mounting seat 203 is fixed to the top of the rotating cylinder 210 by bolts, and a first stopper 204 and a second stopper 211 are respectively mounted on both ends of one side of the stopper mounting seat 203 through mounting frames.

[0036] When in use, the first gear stopper 204 and the second gear stopper 211 cooperate with the first stopper 205 and the second stopper 209 to limit the rotating plate 206 .

[0037] For example, Figure 3 As shown, the utility model also includes that the top of the rotating plate 206 is equidistantly connected to a support column 208 through a threaded groove, positioning pins 207 are set at both ends of the top of the rotating plate 206, and positioning holes 302 corresponding to the positioning pins 207 are opened at both ends of the bottom of the frame 301.

[0038] When in use, the support column 208 is used to support the carrying plate 304 .

[0039] For example, Figure 2 , Figure 3 As shown, the utility model also includes that a guide sleeve 110 is equidistantly penetrated through the top of the lifting cylinder mounting plate 109, and a guide shaft 215 is equidistantly fixed to the bottom of the rotating cylinder mounting plate 214 by bolts, and the bottom end of the guide shaft 215 is inserted into the guide sleeve 110.

[0040] When in use, the guide sleeve 110 cooperates with the guide shaft 215 to guide the lifting movement and enhance the structural stability of the rotating component 2.

[0041] When the utility model is in use, the lifting assembly 1 is installed on the aluminum profile of the conveying section 4, and the rotating assembly 2 is installed on the lifting cylinder piston rod 105 of the lifting assembly. As the lifting cylinder piston rod 105 is lifted synchronously, the pallet 3 is on the conveying section 4 before being lifted;

[0042] The lifting cylinder 108 is a double-acting cylinder with two air pipe joints 107 on the cylinder. Two upper and lower magnetic switches 106 are installed on the side of the lifting cylinder 108 to detect the position of the piston of the lifting cylinder 108. In order to ensure that the lifting cylinder 108 does not drop after lifting, the air inlet pipe joint 107 at the lower end of the lifting cylinder 108 is always ventilated after lifting until the air inlet direction is changed when the cylinder drops. The four guide sleeves 110 cooperate with the four guide shafts 215 of the rotating assembly to guide the lifting movement and enhance the structural stability.

[0043] The rotating assembly is realized by a highly integrated rotating cylinder 210. When the first air port 201 takes in air and the second air port 202 exhausts air, the center of rotation rotates counterclockwise; when the second air port 202 takes in air and the first air port 201 exhausts air, the center of rotation rotates clockwise. Two positioning pins 207 are installed on the rotating plate 206 on the output shaft of the rotating cylinder 210. When the rotating assembly 2 is lifted, the two positioning pins 207 are inserted into the positioning holes 302 at the bottom of the tray 3 to realize the positioning of the tray 3 and improve the accuracy of workpiece processing, assembly or testing. Five support columns 208 support the bearing plate 304 to improve the stability of the tray 3. Two 90° points are installed at the bottom of the rotating plate 206. The first stopper 205 and the second stopper 209 of the cloth are provided. When the rotation is limited, the first stopper 205 is stopped by the first stopper 204. When the rotation is limited by 90°, the second stopper 209 is stopped by the second stopper 211, so that the tray 3 is reversing by 390°. When the second stopper 209 is cancelled, the rotating assembly 2 can complete a 180° rotation, so that the tray 3 is reversing by 180°. The first magnetic switch 212 and the second magnetic switch 213 are installed on the side of the rotating cylinder 210 for detecting the position of the piston of the rotating cylinder 210. In order to ensure that there is no rebound after the rotation is stopped, the rotating cylinder 210 is always ventilated to ensure that the rotating cylinder 210 accurately realizes a 90° or 180° rotation.

[0044] The sequence of lifting and rotating positioning is as follows:

[0045] 1. During lifting: air is taken in from the air pipe joint 107 at the lower end, the piston rod 105 extends, the rotating assembly 2 is lifted, the positioning pin 207 on the rotating plate is inserted into the positioning hole 32 of the tray, and the tray 3 is fixed. In order to ensure that the lifting cylinder 108 does not descend after lifting, the air inlet pipe joint 107 at the lower end of the lifting cylinder 108 is always ventilated after lifting until the air inlet direction is changed when the cylinder descends.

[0046] 2. During rotation: the second air port 202 takes in air, the first air port 201 discharges air, and the rotation center of the rotating cylinder 210 rotates clockwise, driving the upper rotating plate 206 and the upper tray 3 to rotate clockwise. When the second block 209 reaches the second stop 211, the rotation is stopped, and the tray 3 completes a 90° clockwise reversal. If the second block 209 is removed and the first block 205 reaches the first stop 204, the rotation is stopped, and the tray 3 completes a 180° clockwise reversal. In order to ensure that there is no rebound after the rotation is stopped, the rotating cylinder 210 is always ventilated to ensure that the rotating cylinder 210 accurately realizes a 90° or 180° rotation.
