[0002] In the coiling industry, the clamping of the coiling shaft is generally achieved by using an inclined-push type safety chuck. Its working principle is as follows: rotate the safety chuck to a specified position, open the safety chuck by inclined pushing, place the coiling shaft with the coiled material into the clamping opening of the safety chuck, and then manually close the safety chuck or drive the coiling shaft to rotate together through the drive shaft to achieve reset; when it is necessary to replace the coiled material, rotate the safety chuck to the specified position again and open the safety chuck to replace the new shaft.

[0003] A clamping opening is provided on the chuck of the flat-push type safety chuck, and one end of the clamping opening is open, so that one end of the coiling shaft can be placed in the clamping opening through the opening, and then the clamping block is horizontally pushed to move to the opening to block the opening. Furthermore, the clamping block cooperates with the clamping opening to achieve the purpose of clamping the coiling shaft. However, this clamping method can only clamp coiling shafts of the same length. For coiling shafts of different lengths, the position of the entire safety chuck needs to be adjusted, that is, the safety chuck needs to be disassembled and reassembled, so to a certain extent, the use range of the safety chuck is limited. Therefore, we propose a flat-push type safety chuck. Summary of the Utility Model

Detailed implementation manner

[0020] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application.

[0021] Please refer to Figures 1-4 , the present application provides a flat - push type safety chuck, which includes a mounting base 10. A housing 20 with an open end is mounted on the mounting base 10. A rotating shaft assembly 30 is rotatably penetrated through the side wall of the housing 20. A clamping head 40 is mounted on the rotating shaft assembly 30. A pushing mechanism 50 is rotatably connected to the side wall of the mounting base 10. One end of the rotating shaft assembly 30 is rotatably connected to the pushing mechanism 50. Specifically, the rotating shaft assembly 30 rotatably penetrates through the side wall of the housing 20 and can horizontally slide on the housing 20. The pushing mechanism 50 is mounted on the side wall of the mounting base 10. By pushing the rotating shaft assembly 30 horizontally through the pushing mechanism 50, the clamping head 40 can be driven to move. When clamping a winding shaft, both ends of the winding shaft are respectively inserted into the clamping heads 40 on both sides. The clamping heads 40 on both sides are respectively driven by the pushing mechanisms 50 on both sides to move, so that winding shafts of different lengths can be clamped.

[0022] Refer to Figure 2 , the rotating shaft assembly 30 includes a rotating shaft 310 that rotatably penetrates through the side wall of the housing 20. One end of the rotating shaft 310 is fixedly connected with a mounting disc 320, and the other end thereof is rotatably connected to the pushing mechanism 50. The clamping head 40 is mounted on the mounting disc 320. When setting, the rotating shaft 310 rotates on the housing 20. At the same time, the specific connection structure between the rotating shaft 310 and the housing 20 is prior art. The rotating shaft 310 is driven to move horizontally by the pushing mechanism 50, and the rotation of the winding shaft drives the rotating shaft 310 to rotate.

[0023] Refer to Figure 2 , a connecting pipe 330 is fixedly mounted on one end side wall of the mounting disc 320. A support ring 340 is fixedly sleeved on the connecting pipe 330. The support ring 340 is in contact with the inner wall of the housing 20. Specifically, the support ring 340 can move in the housing 20. The support ring 340 cooperates with the connecting pipe 330 to support the rotating shaft 310, so as to support the clamping head 40.

[0024] Refer to Figure 2 and4 On the outer side wall of the outer ring of the support ring 340, a plurality of grooves 3410 are formed. A plurality of rollers 3420 are installed in the plurality of grooves 3410. It should be noted that a plurality of grooves 3410 are formed in the support ring 340, and the rollers 3420 are installed in the grooves 3410. The rollers 3420 are in rolling connection with the inner wall of the housing 20, thereby reducing the frictional resistance between the support ring and the inner wall of the housing 20.

[0025] Refer to Figure 3 On the mounting plate 320, a plurality of screw holes 350 are formed. A plurality of screw rods 360 penetrate through the clamping head 40 in a sliding manner. The plurality of screw rods 360 are respectively connected to the plurality of screw holes 350, so as to fix the clamping head 40 on the mounting plate 320. Specifically, a plurality of through holes are formed in the clamping head 40. The plurality of through holes can correspond to the plurality of screw holes 350. At the same time, the cross sections of the plurality of through holes are in a T-shaped arrangement. Thus, the screw rods 360 are passed through the through holes and connected to the screw holes 350, and the clamping head 40 can be mounted on the mounting plate 320.

[0026] Refer to Figure 2 The pushing mechanism 50 includes a threaded rod 510 rotatably connected to the side wall of the mounting base 10. A connecting block 520 is sleeved on the threaded rod 510 in a threaded manner. A connecting plate 530 is fixedly installed on the top of the connecting block 520. One end of the rotating shaft 310 is rotatably connected to the connecting plate 530. Specifically, by rotating the threaded rod 510, the threaded rod 510 can drive the connecting block 520 to move horizontally, so that the connecting block 520 drives the rotating shaft 310 to move horizontally.

[0027] Refer to Figure 2 The mounting base 10 includes a bottom plate 110. A support plate 120 is fixedly installed on the top of the bottom plate 110. The housing 20 is fixedly installed on the top of the support plate 120. One end of the threaded rod 510 is rotatably connected to the side wall of the support plate 120. A plurality of mounting holes 130 are formed in the bottom plate 110. During the setting, the safety chuck of the present application can be mounted on the existing equipment through the bottom plate 110. Specifically, it can be installed through the existing bolt and nut connection structure. The support plate 120 supports the housing 20.

[0028] When the flat-pushing type safety chuck is in use: the bottom plate 110 is installed on the existing equipment, and then the two ends of the winding shaft can be respectively corresponding to the two clamping heads 40. Rotate the threaded rod 510 to drive the connecting block 520 to move, so that the connecting block 520 drives the rotating shaft 310 to move horizontally through the connecting plate 530. The rotating shaft 310 drives the mounting plate 320 to move horizontally, so that the mounting plate 320 drives the clamping head 40 to move towards the winding shaft, so that one end of the winding shaft is inserted into the clamping head 40. Further, the other clamping head 40 can be moved to be connected to the other end of the winding shaft in the above-mentioned manner.

[0029] It should be noted that the specific model and specification of the clamping head 40 need to be selected according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail here.

For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application. It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.
