The principle of the utility model is as follows: when the shaft-changing manipulator is opposite to the bobbin, the clamping jaw bodies on two sides of the manipulator are opposite to the limiting ends at two ends of the bobbin (the limiting ends are thin round or similar round sheets, which is common knowledge and is not described again). The mechanical arm for changing the shaft is pressed down, the sheet body contacts the limiting end of the spool, the stress is expanded to the end part of the two spools after the diameter of the limiting end is larger, the sheet body is not expanded any more, and the spool enters between the sheet bodies and is positioned by the two sheet bodies. The lamellar body resets and locks the spacing end of spool on the lamellar body. The end package of lamellar body is in the outside of spacing end, during the atress, produces and promotes the lamellar body around lamellar body middle part pin joint pivoted power, and this power drive lamellar body rotates with the terminal outside gesture of lamellar body, and the head of lamellar body is enstrophed, and the dwang also inwards rotates. Because the connecting rod is connected with the upper rod through threads and the upper rod is elastically connected with the lower plate, the upper rod and the lower plate are close to each other by overcoming the elastic force. The shaft-changing manipulator continues to move, the tail end of the sheet body crosses the widest position of the limiting end and then moves reversely along the outline of the limiting end, and the circle center of the limiting end is higher than the tail end of the sheet body, so that clamping is finished. Correspondingly, under the action of the elastic force, the upper rod and the lower plate are reset. After the bobbin is conveyed to the designated position after the clamping is completed, the connecting rod is rotated after the position of the upper plate is limited (the specific structure is a structure which can be realized by a person skilled in the art and is not described in detail), so that the distance between the upper rod and the lower plate is reduced, the driving sheet body is turned outwards again, and the connecting rod is reversely reset after the bobbin is placed. The whole process of the structure can realize the functions of clamping and putting down only by rotating the connecting rod. The clamping jaw bodies on two sides work simultaneously, and a better clamping effect is provided.

Preferably, the lower plate is provided with a sliding hole, the connecting rod is inserted into the sliding hole, one end of the connecting rod, which extends out of the lower plate, is provided with a butting disc, and the diameter of the butting disc is larger than that of the sliding hole. The abutting disc prevents the connecting rod from dropping off the lower plate.

Preferably, a chuck is eccentrically fixed to the tail of the sheet body, and the posture of the chuck relative to the tail of the sheet body enables the chuck to be subjected to outward turning force when the chuck abuts against the limiting end. The chuck can reduce the component force in other directions in the process of pressing down, and the spool is prevented from bouncing after the external force disappears suddenly after being placed.

Preferably, the outer edge of the chuck is provided with an inwards concave positioning groove, and the positioning groove is adapted to the limiting end. The structure can better position the limiting end.

Preferably, the spacing between the two chucks is smaller than the diameter of the stopper.

Preferably, the elastic member is fitted over the connecting rod. The structure is limited by the connecting rod and is not easy to dislocate in the using process.

Preferably, the two pieces are symmetrically arranged on the clamping jaw body.

Preferably, the two jaw bodies are arranged symmetrically.

Compared with the prior art, the utility model has the beneficial effects that: (1) the structure simplifies the driving structure, and the positioning can be realized only by the positive and negative rotation of the connecting rod; (2) the clamping jaw is prevented from contacting the enameled wire part, so that the enameled wire is protected.

Example (b):

a shaft-changing manipulator for a rewinder, as shown in figures 3, 4, 6 and 7, for taking out and putting in a bobbin 1 between a plurality of positioning rollers, comprises a jaw body 3 corresponding to a left and a right limit end 2 of the bobbin 1 respectively, two jaw bodies 3 symmetrically arranged, an upper rod 4 and a lower plate 5 connecting the two jaw bodies 3 and a connecting rod 6, the connecting rod 6 is connected with the upper rod 4 in a threaded manner and is connected with the lower plate 5 in a sliding manner,

an elastic piece 7 is arranged between the upper rod 4 and the lower plate 5, and the elastic piece 7 is sleeved on the connecting rod 6. The structure is limited by the connecting rod 6 and is not easy to dislocate in the using process.

Be equipped with the sliding hole on the hypoplastron, the connecting rod cartridge is in the sliding hole, and the one end that the connecting rod stretches out the hypoplastron is equipped with butt dish 9, and butt dish 9's diameter is bigger than the sliding hole. The abutment disc 9 prevents the connecting rod from coming out of the lower plate.

The clamping jaw body 3 comprises two sheet bodies 12, wherein the two sheet bodies 12 are symmetrically arranged on the clamping jaw body 3, the middle part of the sheet body 12 is rotatably connected onto a lower plate 5, a rotating rod 8 is hinged onto an upper rod 4, and the head part of the sheet body 12 is hinged to the rotating rod 8. The tail part of the sheet body 12 is eccentrically fixed with a chuck 10, and the posture of the chuck 10 relative to the tail part of the sheet body 12 causes the chuck 10 to be subjected to outward turning force when abutting against the limiting end 2. The chuck 10 can reduce the component force in other directions during the pressing process, and prevent the bobbin 1 from bouncing after the external force disappears suddenly after the bobbin is placed in the bobbin. As shown in fig. 5, the outer edge of the chuck 10 is provided with a concave positioning groove 11, and the positioning groove 11 is adapted to the position-limiting end 2. The structure can better position the limiting end 2. The distance between the two chucks 10 is smaller than the diameter of the spacing end 2.

The principle of the utility model is as follows: when the shaft changing manipulator is opposite to the bobbin 1, the clamping jaw bodies 3 at two sides of the manipulator are opposite to the limiting ends 2 at two ends of the bobbin 1 (the limiting ends 2 are thin round or similar round bodies 12, which is common knowledge and is not described herein again). The shaft changing mechanical arm is pressed down, after the sheet body 12 contacts the limiting end 2 of the spool 1, the stress is expanded to the end part of the two spools 1, the diameter of the limiting end 2 is larger, the sheet body 12 is not expanded, and the spool 1 enters between the sheet bodies 12 and is positioned by the two sheet bodies 12. The sheet body 12 is reset to lock the limiting end 2 of the bobbin 1 on the sheet body 12. The end package of lamellar body 12 is in the outside of spacing end 2, and during the atress, the production promotes lamellar body 12 around lamellar body 12 middle part pin joint pivoted power, and this power drive lamellar body 12 rotates with the terminal outside gesture of lamellar body 12, and the head of lamellar body 12 is turned over inwards, and dwang 8 is inwards rotated too. Since the connecting rod 6 is screwed to the upper rod 4 and the upper rod 4 is elastically connected to the lower plate 5, the upper rod 4 and the lower plate 5 are approached against the elastic force. The shaft-changing manipulator continues to move, the tail end of the sheet body 12 crosses the widest position of the limiting end 2 and then moves reversely along the outline of the limiting end 2, and at the moment, the circle center of the limiting end 2 is higher than the tail end of the sheet body 12, so that clamping is finished. Correspondingly, under the action of the elastic force, the upper rod 4 and the lower plate 5 are reset. After the bobbin 1 is conveyed to a designated position after the clamping is completed, after the position of the upper plate is limited (the specific structure is a structure which can be realized by those skilled in the art and is not described in detail), the connecting rod 6 is rotated, so that the distance between the upper rod 4 and the lower plate 5 is reduced, the driving sheet body 12 is turned outwards again, and the connecting rod 6 is reversed and reset after the bobbin 1 is put down. The whole process of the structure can realize the functions of clamping and putting down only by rotating the connecting rod 6. The clamping jaw bodies 3 on both sides work simultaneously, and a better clamping effect is provided.

The above-described embodiments are merely preferred embodiments of the present invention, which is not intended to be limiting in any way, and other variations and modifications are possible without departing from the scope of the utility model as set forth in the appended claims.
