[0044] The positioning support frame 19 is provided with a first position sensor 58 and a second position sensor 59. When the right positioning clamping jaw 22 is in different states, the two sensors can be triggered respectively.

[0045] The working process of the squirrel-cage type turnover device is as follows: the workpiece 31 needing turnover operation is placed on the tray 32, the tray 32 is moved to the device under the action of the conveying mechanism of the production line, when the front half of the tray 32 is moved to the position of the positioning and jacking assembly 5 at the front end, the bottom end surface of the tray 32 will be in contact with and supported by the second roller 27, the tray 32 is separated from the production line under the action of the second roller 27 and enters the device, when the tray 32 is moved to the tray stop block 33 on the bottom end surface collides with the limiting stop block 30, the movement is stopped, at this time, the tail end of the tray 32 is located within the range of one positioning and jacking assembly 5, the middle part is supported by the plurality of pairs of first rollers 26 in the squirrel-cage frame 2, and the front end is located on another positioning and jacking assembly 5;

[0046] The tray positioning assembly 4 acts to clamp the protruding member on the bottom end surface of the tray 32, thereby positioning the tray 32 in the direction of movement (the direction is defined as the X-axis direction), then the correction lifting frame 35 in the two positioning and jacking assemblies 5 is lifted by a certain distance to adjust the tray 32 in the Y-axis direction (the tray 32 can move relative to the tray positioning assembly 4 in the Y-axis direction), after the above operation, the tray 32 is adjusted in place in the X-axis direction and the Y-axis direction of the horizontal plane, then the tray positioning assembly 4 is opened, the positioning and jacking assembly 5 continues to be lifted to lift the tray 32 and the workpiece 31 thereon, the workpiece 31 is moved to the height corresponding to the workpiece clamping mechanism, the control system controls the workpiece clamping mechanism to act to clamp the workpiece 31, at this time, the workpiece 31 is relatively fixed with the squirrel-cage frame 2, the positioning and jacking assembly 5 falls, the tray 32 is separated from the workpiece 31, the second roller 27 is driven to rotate by the roller motor 28 in the positioning and jacking assembly 5 to convey the tray 32 to the outside of the squirrel-cage frame 2 and be supported by the plurality of second rollers 27 in the positioning and jacking assembly 5 at the far end;

[0047] The power assembly 3 works to drive the squirrel-cage frame 2 to rotate at a constant speed through the four bottom support assemblies 1, stop after rotating 180°, the above action is reversed, the tray 32 is repositioned in the squirrel-cage frame 2 and is lifted to the height of contacting the workpiece 31, all the workpiece clamping mechanisms release the workpiece 31, the workpiece 31 is supported by the tray 32 again, then the tray 32 and the workpiece 31 are lowered together and are reversely moved under the action of the positioning and jacking assembly 5 to reposition in the production line;

[0048] In the above action process, before the workpiece clamping mechanism clamps the workpiece 31, the squirrel cage frame 2 needs to be locked first. When the squirrel cage frame 2 is rotated to the position and the positioning groove 51 is just moved to the upper side of the locking block 53, the control system sends a signal to the locking cylinder 52, the locking cylinder 52 drives the locking block 53 to extend, and the V-shaped part 55 at the end thereof is inserted into the positioning groove 51. Since the V-shaped part 55 and the positioning groove 51 are both provided with inclined surfaces, the relative position between the two can be automatically adjusted during the insertion process, so as to adjust the rotation angle of the squirrel cage frame 2.

[0049] When the power assembly 3 works, the motor 7 in it works, drives the two output ends of the double-output gearbox 6 to rotate at the same time, drives the chain wheels 9 on both sides to rotate, and the chain wheels 9 will drive the chain 11 to move when rotating. Since the chain 11 is wound on the fixed member outside the annular member 12, and the annular member 12 is supported by a pair of second limiting wheels 15, the chain 11 will drive the annular member 12 (i.e. drive the squirrel cage frame 2) to rotate. Since the end surface of the annular member 12 is in contact with the first limiting wheel 14, the first limiting wheel 14 at both ends limits the axial direction of the squirrel cage frame 2.

[0050] When the tray positioning assembly 4 works, the positioning cylinder 20 works, directly drives the right positioning jaw 22 to swing relative to the positioning support frame 19. When the right positioning jaw 22 swings, it will drive the left positioning jaw 21 to swing through the connecting rod 23. The swinging amplitudes of the left and right positioning jaws are the same, and the directions are opposite, so as to realize the clamping or releasing action. When the positioning clamping blocks 25 on the left and right positioning jaws clamp the protruding members at the bottom of the tray 32, the tray 32 is fixed. The first position sensor 58 and the second position sensor 59 can be triggered in different states of the right positioning jaw 22 respectively, that is, the clamping state or the non-clamping state of the tray positioning assembly 4 can be judged through the triggering states of the two sensors.

[0051] When the workpiece clamping mechanism works, the control system sends a signal to the feed motor 45, the feed motor 45 drives the lead screw 46 to rotate, and then drives the jaw support 47 to move along the clamping mechanism guide rail 44. The jaw support 47 approaches the workpiece 31 until the workpiece 31 is clamped between the two clamping blocks 49, and the top block 50 is in contact with the side wall of the workpiece. Since the workpiece clamping mechanism includes four jaw supports 47, when all the jaw supports 47 are moved to the position, the workpiece 31 is clamped and fixed by them. At this time, the tray 32 can be separated from the workpiece 31.

[0052] When the positioning and lifting assembly 5 is working, the correction electric cylinder 34 works to drive the correction lifting frame 35 to rise. In the process of upward movement of the correction lifting frame 35, the two correction wheels 36 will first contact the arc surfaces on the two sides of the bottom of the correction block 39. Since the width of the correction block 39 matches the spacing between the two correction wheels 36, the process of the correction block 39 entering between the two correction wheels 36 actually plays a role in correcting the positional accuracy of the tray 32 in the width direction. Then the correction lifting frame 35 continues to rise. Since the position of the tray 32 has been corrected at this time, the positioning pin 40 can smoothly insert into the pin hole opened at the bottom of the tray 32. After the positioning pin 40 is inserted, further positioning of the tray 32 is achieved.

[0053] When the correction lifting frame 35 rises to the height at which the lower support block 41 on the correction lifting frame 35 contacts the upper support block 42 at the bottom of the tray 32, the weight of the tray 32 is no longer borne by the first roller 26 or the second roller 27, but is instead borne by the correction lifting frame 35. That is, the correction lifting frame 35 can drive the tray 32 and the workpiece 31 thereon to rise to a height matching the workpiece clamping mechanism.
