DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 - Figure 2 As shown, it includes a workbench 1, on which two clamping blocks 3 are symmetrically arranged, and two groups of driving structures with symmetrical structures are symmetrically arranged on both sides of the workbench 1. Several movable grooves 2 are opened on the workbench 1, and the two groups of driving structures are connected to the rear sides of the two clamping blocks 3 through driving rods 21 vertically arranged in the movable grooves 2, and both groups of driving structures are connected with anti-retraction components.

[0022] See also Figure 1 - Figure 4 As shown, the driving structure includes a driving motor 5 arranged in the workbench 1, the output shaft of the driving motor 5 is connected to the driving gear 16 through gear meshing, one side of the driving gear 16 is provided with a connecting gear 12 meshing therewith, one side of the connecting gear 12 is provided with a slide rail 14, the slide rail 14 is provided with a slider 15, and the slider 15 is provided with a rack 13 meshing with the connecting gear 12; the connecting gear 12 is connected to the connecting gear 2 16 through a connecting gear set 17, the number of gears in the connecting gear set 17 is an odd number, and one of the gears is installed on the same rotating shaft as the connecting gear 2 16, and the position of the connecting gear 2 16 is higher than the connecting gear 12; a slide rail 2 18 is provided directly above the slide rail 14, a slider 2 19 is slidably installed on the slide rail 2 18, and one side of the slider 2 19 is provided with a rack 20 meshing with the connecting gear 2 16, and the rear sides of the two clamping blocks 3 are respectively connected to the rack 13 and the rack 2 20 through a driving rod 21.

[0023] As an optimization scheme of the utility model, the driving motor 5 drives the driving gear 16, the connecting gear 12, the connecting gear set 17 and the connecting gear 2 16 to rotate, and because the number of gears in the connecting gear set 17 is an odd number, the rotation direction of the gear coaxial with the connecting gear 2 16 is opposite to that of the connecting gear 12, that is, the rotation direction of the connecting gear 12 and the connecting gear 2 16 is opposite, so that the connecting gear 12 drives the rack 13 to slide along the slide rail 14, and the connecting gear 2 16 drives the rack 2 20 to slide along the slide rail 2 18, and the moving directions of the rack 13 and the rack 2 20 are opposite, and then the driving rod 21 drives the two clamping blocks 3 above to move closer or farther at the same time.

[0024] See also Figure 1 - Figure 3As shown, the anti-retreat component includes a ratchet wheel 7 installed on the same rotating shaft as the first driving gear 6. A pawl 8 is provided on one side of the ratchet wheel 7 and is rotatably installed on a mounting shaft provided in the workbench 1. A torsion spring 9 is provided on the mounting shaft. One end of the torsion spring 9 is connected to the mounting shaft, and the other end of the torsion spring 9 is connected to the pawl 8. A magnetic block 10 is provided on the side of the pawl 8 away from the ratchet wheel 7. A micro electromagnet 11 is provided on one side of the magnetic block 10, and a distance of 1 - 2 cm is left between the micro electromagnet 11 and the magnetic block 10.

[0025] As an optimized solution of the present invention, the ratchet wheel 7 rotates synchronously with the first driving gear 6. At the same time, the ratchet wheel 7 pushes the pawl 8 outwards, and the torsion spring 9 will press the pawl 8 inwards, thereby preventing the ratchet wheel 7 from reversing. When it is necessary to release the pawl 8, only the micro electromagnet 11 needs to be energized. The micro electromagnet 11 uses magnetic force to attract the magnetic block 10, and the pawl 8 can be pulled open, no longer restricting the ratchet wheel 7, so that the ratchet wheel 7 and the lower first driving gear 6 can rotate freely.

[0026] See Figure 1 - Figure 4 As shown, a flexible clamping head 4 is provided on the front side of the clamping block 3.

[0027] As an optimized solution of the present invention, the flexible clamping head 4 can prevent damage to the surface of the processed fitting due to hard contact during clamping.

[0028] The usage process of the present invention:

[0029] First, place the fitting to be clamped between the two clamping blocks 3, and then start the two driving motors 5 to rotate in the same speed and opposite directions. Drive the two upper clamping blocks 3 to approach simultaneously through the first rack 13 and the second rack 20 to clamp the fitting. At the same time, the pawl 8 can limit the position of the ratchet wheel 7 to prevent it from reversing, so as to keep the fitting from falling off during the processing.

[0030] After the processing is completed, only energize the two micro electromagnets 11, and the two pawls 8 can be pulled open by magnetic force. Then start the two driving motors 5 to rotate back, drive the two clamping blocks 3 to move backward, and the fitting can be easily taken out.

[0031] It should be understood that the above specific embodiments of the present invention are only used for exemplary illustration or explanation of the principle of the present invention, and do not constitute a limitation to the present invention.
