[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-5 , the present invention provides a technical solution: a positioning device for PU sole processing, including a base 1 and a support column 2, and the periphery of the bottom surface of the base 1 is fixedly connected to the support column 2; a connecting frame 3 is fixedly connected to the top surface of the base 1, and an electric push rod 4 is fixedly connected to the middle of the bottom surface of the connecting frame 3, and a processing device 5 is fixedly installed on the bottom surface of the electric push rod 4; further included: a positioning component 6 is arranged on the top surface of the base 1; wherein, the positioning component 6 includes a base plate 601 slidably connected to the base 1, and two sides of the top surface of the base plate 601 are symmetrically provided with slide plates 602, and a slide block 603 is slidably connected to the top surface of the slide plate 602; wherein, a connecting plate 604 is fixedly installed on one side of the top surface of the slide block 603, an extension rod 605 is fixedly connected to one side surface of the slide block 603, and a first spring 606 is fixedly connected to one side surface of the extension rod 605, as Figure 1 , 2 , shown in Figures 3 and 5, by setting the positioning component 6, it is possible to position and clamp soles of different sizes, thereby improving the clamping stability of the soles, and at the same time increasing the friction between the positioning component 6 and the soles, so as to prevent the occurrence of deviation when processing the soles. At the same time, the model of the electric push rod 4 is LAM33-A, and the electric push rod 4 and the processing device 5 are installed and fixed by bolts.

[0030] A connecting block 607 is fixedly installed in the middle of the top surface of the bottom plate 601. A rotating block 608 is rotatably connected to the middle of the surface of the connecting block 607 close to the top. A top block 609 is fixedly connected to one side surface of the rotating block 608. Both sides of the top block 609 are in fit connection with the connecting plate 604. The rotating block 608 and the connecting block 607 are connected through. A stabilizing plate 610 is fixedly connected to one side surface of the connecting plate 604. A number of second springs 611 are fixedly installed on the bottom surface of the stabilizing plate 610. The bottom of the second spring 611 is fixedly connected with a clamping plate 612. A number of friction balls 613 are fixedly installed on the bottom surface of the clamping plate 612. As Figure 2 、 3 、5 shown, by rotating the rotating block 608, the rotating block 608 can drive the rotation of the top block 609, so that the top block 609 will extrude the connecting plate 604, so that the slider 603 moves on the sliding plate 602. At the same time, when the slider 603 moves, the first spring 606 will be stretched, so that the first spring 606 deforms. At the same time, after moving the two clamping plates 612 to the appropriate size of the shoe sole, by placing the shoe sole on the base 1, by loosening the rotating block 608, after no supporting force is applied to the top block 609, the connecting plate 604 and the slider 603 will move towards the middle under the action of the first spring 606. Through the movement of the connecting plate 604 and the slider 603, the second spring 611, the clamping plate 612 and the friction balls 613 on the stabilizing plate 610 are closely attached to the side surface of the shoe sole. At the same time, when the friction balls 613 are in contact with the clamping plate 612 and the side surface of the shoe sole, the second spring 611 deforms. At the same time, due to the characteristics of the second spring 611, the clamping plate 612 will be extruded, so that the contact between the clamping plate 612 and the friction balls 613 and the shoe sole is closer. At the same time, the friction balls 613 can increase the friction with the shoe sole, so as to ensure that the shoe sole will not shift during processing, so as to ensure the improvement of the processing efficiency of the shoe sole. At the same time, the first spring 606 is a tension spring in the prior art, the second spring 611 is a rubber composite spring in the prior art, the elastic force of the first spring 606 is greater than that of the second spring, and the friction balls 613 are made of rubber, so as to increase the friction with the shoe sole.

[0031] A groove 7 is formed in the middle of the top surface of the base 1. A double-headed lead screw 8 is rotatably connected inside the groove 7. A thread sleeve 9 is sleeved on the surface of the double-headed lead screw 8. The top surface of the thread sleeve 9 is fixedly connected with the bottom plate 601. One side surface of the double-headed lead screw 8 away from the groove 7 is connected through the base 1. As Figure 4As shown in the figure, by rotating the double-headed lead screw 8, the rotation of the double-headed lead screw 8 can drive the movement of the threaded sleeve 9. At the same time, the threaded sleeve 9 is fixedly connected to the bottom plate 601, so that the cooperation between the bottom plate 601 and the base 1 can limit the threaded sleeve 9, so that the threaded sleeve 9 can move horizontally on the double-headed lead screw 8. At the same time, through the movement of the threaded sleeve 9, the movement of the bottom plate 601 can be driven, so that the positioning assembly 6 can be adjusted according to the size of the shoe sole, so that the positioning of the shoe sole can be improved, thus ensuring the processing efficiency of the shoe sole.

[0032] Working principle: Before using this positioning device for PU shoe sole processing, it is necessary to first check the overall situation of the device to ensure that it can work properly. According to Figure 1 - Figure 5 As shown in the figure, first, after placing the shoe sole on the base 1, by rotating the double-headed lead screw 8, the rotation of the double-headed lead screw 8 can drive the movement of the threaded sleeve 9. At the same time, the threaded sleeve 9 is fixedly connected to the bottom plate 601, so that the cooperation between the bottom plate 601 and the base 1 can limit the threaded sleeve 9, so that the threaded sleeve 9 can move horizontally on the double-headed lead screw 8. At the same time, through the movement of the threaded sleeve 9, the movement of the bottom plate 601 can be driven, so that the positioning assembly 6 can be adjusted according to the size of the shoe sole, so that the positioning of the shoe sole can be improved, thus ensuring the processing efficiency of the shoe sole.

[0033] Secondly, when processing shoe soles of different sizes, by rotating the rotating block 608, the rotating block 608 can drive the rotation of the top block 609, so that the top block 609 will squeeze the connecting plate 604, so that the slider 603 moves on the sliding plate 602. At the same time, when the slider 603 moves, the first spring 606 will be stretched, so that the first spring 606 deforms. At the same time, after moving the two clamping plates 612 to the appropriate size of the shoe sole, by placing the shoe sole on the base 1, when the rotating block 608 is loosened so that no supporting force is applied to the top block 609, the connecting plate 604 and the slider 603 will move towards the middle under the action of the first spring 606. Through the movement of the connecting plate 604 and the slider 603, the second spring 611, the clamping plate 612 and the friction ball 613 on the stabilizing plate 610 are closely attached to the side of the shoe sole. At the same time, when the friction ball 613 is attached to the clamping plate 612 and the side of the shoe sole, the second spring 611 deforms. At the same time, due to the characteristics of the second spring 611, the clamping plate 612 will be squeezed, so that the clamping plate 612 and the friction ball 613 are in closer contact with the shoe sole. At the same time, the friction ball 613 can increase the friction with the shoe sole, so that it is ensured that the shoe sole will not shift during processing, thus ensuring the improvement of the processing efficiency of the shoe sole.
