[0029] Example

[0030] Reference Figure 1-Figure 7 As shown, a housing automatic positioning and locking device of the utility model comprises:

[0031] The frame mechanism comprises: a fixed frame 5, a movable plate 10 movably connected to the fixed frame 5, and a driving member 7 arranged on the fixed frame 5 and having an output end connected to the movable plate 10, wherein the movable plate 10 is used to clamp the workpiece to be locked;

[0032] The locking mechanism includes: a first groove body 11 opened in the movable plate 10, a shaft 13 with one end arranged on the fixed frame 5 and the other end extending and passing through the first groove body 11, a rotating seat 18 arranged on the movable plate 10, a pressing piece 14 with one end rotatably connected to the rotating seat 18 and the other end capable of rotating and pressing against a workpiece to be locked, and an elastic piece 21 with two ends respectively abutting against the rotating seat 18 and the pressing piece 14.

[0033] The utility model discloses an automatic positioning and locking device for a shell, wherein a movable plate 10 is used to place a workpiece to be locked, and a driving member 7 is used to drive the movable plate 10 and a rotating seat 18 to move up and down synchronously. When locked, the rotating seat 18 is limited and guided downward by the supporting shaft 13, so that the pressing member 14 is rotated toward the fixed part of the workpiece, and the elastic member 21 is compressed and the workpiece is crimped and locked. When unlocked, the pressing member 14 and the rotating seat 18 rise, and the height of the pressing member 14 exceeds the supporting shaft 13, so that the pressing member 14 is separated from the supporting shaft 13, and the supporting shaft 13 is reset and squeezed by the elastic member 21 to rotate in the opposite direction, so that the pressing member 14 is rotated outward to be unlocked, thereby realizing automatic locking and unlocking of the shell workpiece.

[0034] The positioning and locking process of the utility model is as follows: 1. The manipulator places the product on the tooling, and the product is positioned by multiple positioning pins distributed around the product; 2. The lifting cylinder descends and drives the pressure block assembly to descend through the pin connection. The pressure block rotates inward under the pressure of the fixed shaft 13 and finally presses the product. The probe of the testing equipment can pass through the space under the movable plate 10 and insert the probe of the bottom part of the shell from below the movable plate 10.

[0035] Reference Figure 3-Figure 5As shown, the rotating seat 18 and the workpiece to be locked are respectively arranged on both sides of the movable plate 10, optimizing the structural space and reducing the space occupied by the rotating seat 18. In this embodiment, the rotating seat 18 and the first locating pin 15, the second locating pin 12 and the locating shaft are arranged below the movable plate 10, and the rotating seat 18 is fixedly connected to the lower side of the movable plate 10, the first locating pin 15, the second locating pin 12, and the supporting shaft 13 are respectively arranged above the fixing frame 5, and the supporting shaft 13 and the pressing piece 14 are passed through the first groove body 11.

[0036] Reference Figure 7 As shown, the rotating seat 18 and the pressing piece 14 are respectively provided with a second groove body 19 adapted to the elastic piece 21. The elastic piece 21 is a compression spring. The compression spring is accommodated by the second groove body 19. The two ends of the compression spring are respectively fixed to the inner wall of the second groove body 19 in the rotating seat 18 and the pressing piece 14.

[0037] Continue to refer to Figure 7 As shown, the rotating seat 18 is provided with a third groove body 20, and the two side walls of the third groove body 20 are rotatably connected with the rotating shaft 17. The pressing piece 14 is rotatably connected to the rotating seat 18 through the rotating shaft 17. The third groove body 20 passes through the rotating seat 18 from top to bottom, and has an opening on one side for the pressing piece 14 to rotate. The side wall on the opposite side of the opening limits the pressing piece 14 so that the rotation angle will not be too large when there is no pressing piece 14, and it can be pressed onto the extension part 2 of the workpiece before reaching the limit. The rotating shaft 17 is arranged on the other two side walls.

[0038] The pressing part 14 includes: a rotating part 141 with one end rotatably sleeved on the rotating shaft 17 and the other end extending and passing through the first groove body 11, and a pressing part 142 arranged at the other end of the rotating part 141. The rotation direction of the rotating part 141 is close to or away from the shaft 13. The lower end of the rotating part 141 is rotatably connected to the rotating seat 18 through the rotating shaft 17, and the upper end is connected with the pressing part 142. The pressing locks or unlocks the extension part 2 of the workpiece during the rotation of the rotating part 141.

[0039] Reference Figure 3-Figure 5As shown, the movable plate 10 is also provided with a first positioning pin 15, which abuts against the extension portion 2 of the workpiece to be crimped, and crimps the extension portion 2 up and down to improve the locking effect. In some embodiments, the end of the first positioning pin 15 passes through the extension portion 2 and is flush with the surface of the extension portion 2, so that the pressing portion 142 can be crimped to the extension portion 2 and the end of the first positioning pin 15. By setting the first positioning pin 15, the workpiece can be limited and positioned to prevent the workpiece from moving along the plane direction. The pressing portion 142 is pressed onto the top of the first positioning pin 15 and the extension portion 2 to further limit the height direction of the workpiece. In some embodiments, an elastic portion is also provided at the top of the first positioning pin 15, and the height of the elastic portion is slightly larger than the extension portion 2. The pressing portion 142 is pressed onto the elastic portion to shrink it, so that the pressing portion 142 is pressed onto the elastic member 21 and the surface of the extension portion 2 at the same time. The pressing portion 142 is buffered by the elastic portion, which can prevent damage to the workpiece during rapid crimping.

[0040] Reference Figure 3-Figure 5 , Figure 7 As shown, the axes of the pressing piece 14, the shaft 13 and the first positioning pin 15 are located in the same plane, the pressing piece 14 and the shaft 13 are successively away from the first positioning pin 15, and the number of the locking mechanism and the first positioning pin 15 are both multiple, such as four or eight, which are evenly arranged around the workpiece.

[0041] Reference Figure 3-Figure 6 As shown, the driving member 7 is a driving cylinder, and the output end of the driving cylinder is connected to a lifting bracket 8. The movable plate 10 is detachably arranged on the fixed frame 5, so that it can be connected to the fixed frame 5 through a quick connection device, such as screws, pins, buckles, etc., so that when the workpiece needs to be replaced or maintenance is required, the movable plate 10 can be easily removed. The fixed frame 5 is provided with a lifting hole 16 for the driving member 7 and the lifting bracket 8 to pass up and down. A fixed plate 6 is provided on the fixed frame 5. The movable plate 10 is movably connected to the fixed plate 6 up and down. A guide sleeve is also provided between the movable plate 10 and the fixed plate 6. The fixed plate 6 is provided with an avoidance groove 9 for the lifting bracket 8 to move up and down.

[0042] Reference Figure 5 As shown, the movable plate 10 is also provided with a plurality of second positioning pins 12, the peripheral sides of the second positioning pins 12 abut against the workpiece to be locked, and the second positioning pins 12 are arranged on the peripheral sides of the movable plate 10 for abutting against corresponding parts of the peripheral sides of the workpiece to be locked, thereby achieving pre-positioning of the workpiece on the movable plate 10.

[0043] Reference Figure 5-Figure 7As shown, the end size of the first positioning pin 15 and / or the second positioning pin 12 gradually increases downward, so that the upper end of the first positioning pin 15 and / or the second positioning pin 12 forms a cone, and the cone surface can be a straight surface or an arc surface. The end of the rotating part 141 close to the rotating shaft 17 is arc-shaped, so that when the rotating part 141 moves downward, it cooperates with the first positioning pin 15 to extrude, limit and guide the rotation more smoothly, thereby increasing the positioning efficiency.
