The traditional mode of automatic centre gripping shoe tree mainly relies on the manipulator of walking to accomplish, and the reliability is not high, the structure is comparatively complicated, area is great.
The Chinese patent with the application publication number of CN201811176464.2 discloses a shoe tree positioning and clamping device, which comprises an outer ring frame and an inner ring frame, wherein a plurality of rollers are uniformly and fixedly embedded in the inner ring frame, the rollers are arranged in the outer ring frame in a sliding manner, shoe tree lifting frames are fixedly arranged in the inner ring frame along the diameter direction of the inner ring frame, an arc-shaped underframe fixedly arranged above the inner ring frame through a supporting frame is arranged between the shoe tree lifting frames, a bottom plate is arranged between the two groups of arc-shaped underframe, one end of the bottom plate is rotatably arranged on the arc-shaped underframe, a rotating handle penetrating through the side surface of the arc-shaped underframe is fixedly arranged on the side surface of the other end of the bottom plate, a micro rotating motor is fixedly arranged above the bottom plate, a lead screw is fixedly arranged at the power output end of the micro rotating motor, the lead screw is mutually meshed with a threaded column rotatably arranged, the integrated operation of clamping, replacing and rotating the shoe tree can be realized. However, the above-mentioned solution is not only complicated in structure, but also has reliability to be considered, and the shoe tree cannot be flexibly moved.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: the disadvantages of the above techniques are overcome. The utility model provides a clamping head that can automatic centre gripping shoe tree can with manipulator or robot cooperation, realizes getting of automation of shoe tree and puts and transport.
In order to solve the technical problem, the utility model provides a technical scheme is: an automatic last gripping head, comprising: the mounting device comprises a mounting body, a positioning rod arranged at the top end of the mounting body and a cylinder arranged in the mounting body; clamping jaws are arranged on the side face of the mounting body; the middle part of the clamping jaw is hinged on the mounting body; a conical head is arranged on a push rod of the air cylinder, a return spring is arranged between the mounting body and the clamping jaw, and the conical head can move between a first position and a second position along the mounting body under the driving of the air cylinder; when the conical head moves from the first position to the second position, the conical head pushes the bottom of the clamping jaw and enables the pair of claws at the top of the clamping jaw to move towards each other against the elastic force of the return spring, and the positioning rod is inserted into the shoe tree; when the cone reaches the second position, the clamping jaws clamp the shoe tree; when the conical head moves from the second position to the first position, the conical head leaves the bottom of the clamping jaw, and the clamping jaw is driven by the reset force of the reset spring to open and release the shoe tree.
The scheme is further improved in that: the bottom of the mounting body is provided with a flange.
The scheme is further improved in that: the clamping jaw bottom is provided with a bearing, and the clamping jaw bottom is contacted with the conical head through the bearing.
The utility model provides an automatic shoe tree clamping head which has compact structure and perfect function, can realize the clamping, moving and taking and placing of various types of shoe trees, can effectively realize the quick taking, placing and shifting of the shoe trees, and reduces the labor intensity of workers; the shoe tree can be placed accurately by matching with an industrial robot, and the shoe tree is more suitable for an automatic production line; the structure design is ingenious, the reliability is high, and the cost is low.
Drawings
The present invention will be further explained with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of a preferred embodiment of the present invention.
Detailed Description
Examples
The automatic last clamping head of this embodiment, as shown in fig. 1, includes: the mounting structure comprises a mounting body 5, a positioning rod 1 arranged at the top end of the mounting body 5 and a cylinder 7 arranged in the mounting body; clamping jaws 3 are symmetrically arranged on the side surface of the mounting body 5; the top of the clamping jaw 3 is provided with a pair of jaws; the middle part of the clamping jaw 3 is hinged on the mounting body 5 through a hinge shaft 2; the push rod of the air cylinder 7 is provided with a conical head 6, and the conical head 6 can move between a first position (shown in a thin line structure in the figure) and a second position along the mounting body 5 under the driving of the air cylinder 7.
When the conical head 6 moves from the first position to the second position, the conical head 6 pushes the bottom of the clamping jaw 3 forward, and a pair of jaws at the top of the clamping jaw 3 are rotated inwards to move towards each other; because the reset spring 4 is arranged between the mounting body 5 and the clamping jaw 3, the pair of jaws at the top of the clamping jaw 3 overcomes the restraint of the reset spring 4 (namely the force applied by the reset spring 4 to the clamping jaw 3 causes the top of the clamping jaw 3 to generate a movement trend far away from the mounting body 5), and the conical head 6 is pushed forwards to simultaneously enable the positioning rod 1 to be inserted into a shoe tree in a front inserting mode; when the cone head 6 reaches the second position, the jaws 3 are just able to grip the last. Thus, the clamping jaw 3 can be driven to clamp by the action of the air cylinder 7.
After the push rod of the cylinder 7 is retracted, the conical head 6 leaves the bottom of the clamping jaw 3, and the clamping jaw 3 is driven by the reset acting force of the reset spring 4 to automatically open again, so that the shoe tree is released. The head of the jaw 3 extends out of the grip towards the mounting body 5, preferably to adapt to the shape of the shoe last.
In order to facilitate the connection of the automatic last gripping head of this embodiment with a robot or robotic arm, the bottom of the mounting body 5 has a flange 8.
In order to reduce friction and avoid jamming, the bottom of the clamping jaw 3 is provided with a bearing, and the bottom of the clamping jaw 3 is contacted with the conical head 6 through the bearing.
The present invention is not limited to the specific technical solutions described in the above embodiments, and other embodiments can be provided in addition to the above embodiments. All the technical schemes formed by adopting equivalent substitution are the protection scope required by the utility model.
