DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0026] Embodiment one

[0027] With reference to Figures 1-4 A spring clamp of a tapping machine, comprising:

[0028] A moving push plate 1;

[0029] An installation plate 2 is fixedly installed on the top of the moving push plate 1, and one side of the installation plate 2 is fixedly installed with a connecting plate 4;

[0030] An installation seat 5 is fixedly installed on the top of the installation plate 2, and the installation seat 5 is provided with a clamping mechanism for clamping and positioning the workpiece;

[0031] A motor 3 is fixedly installed on the bottom of the moving push plate 1, and the bottom of the moving push plate 1 is provided with a guide groove. The clamping mechanism comprises two clamping arms 7. One side of the installation seat 5 is provided with an installation groove 6, and the installation groove 6 is rotatably installed with two symmetrical rotating columns 8. The two clamping arms 7 are fixedly installed on the outer sides of the rotating columns 8. The two ends of a spring 9 are fixedly connected with the inner wall of the fixed groove and the outer side of the rotating column 8. One side of the installation seat 5 is provided with a recess 10, and the recess 10 is matched with two clamping heads 11. The two clamping heads 11 are both provided with a placing groove. The bottom of the two clamping arms 7 is both provided with a fixed groove. The two rotating columns 8 are both located in the two fixed grooves. The outer side of the two rotating columns 8 is both sleeved with the spring 9.

[0032] With reference to Figure 4 One side of the two clamping arms 7 is both provided with a sliding groove 12, and the two sliding grooves 12 are both slidably installed with a sliding plate 13. One side of the two sliding plates 13 is both fixedly connected with the clamping head 11. The two clamping arms 7 are both rotatably installed with a stud 14. The two studs 14 are both threadedly connected with the two sliding plates 13. One end of the two studs 14 is both fixedly installed with a rotating block 15. When the rotating block 15 is rotated, the stud 14 can drive the sliding plate 13 to move horizontally.

[0033] The implementation principle of the spring type clamp of the tapping machine is as follows: in use, the nut falls between the two clamping heads 11 through the blanking mechanism, and the nut step or flange structure falls into the groove 10, the inner wall of the placing groove on the two clamping heads 11 is in contact with the surface of the nut, so that the nut is stably clamped and does not fall off; when it is needed to loosen the nut, only the moving push plate 1 fixed at the bottom of the clamp needs to be moved forward, the movement of the moving push plate 1 can be realized through the motor 3 and the added lead screw, after the nut is sent to the rotating tap, the moving push plate 1 is moved backward through the pulling of the tap to make the nut break away from the two clamping heads 11, and the nut step or flange structure drives the two clamping heads 11, the two sliding plates 13 and the two clamping arms 7 to rotate; when the nut is separated, the two springs 9 drive the two clamping arms 7 to reset respectively, and then the next nut is clamped, so that the reciprocating movement is realized, so that the clamping and loosening can be realized, and the distance between the two clamping heads 11 can be adjusted through the rotation of the rotating block 15, the rotating block 15 drives the stud 14 to rotate, the stud 14 drives the sliding plate 13 and the clamping head 11 to move horizontally, and then the distance between the two clamping heads 11 can be adjusted, so that the nuts of different specifications can be clamped conveniently.

[0034] Embodiment two

[0035] The difference between the embodiment and the embodiment one is that the top of the mounting seat 5 is fixedly provided with a vibration motor, when the vibration motor is started, the vibration motor drives the mounting seat 5 to vibrate, and then drives the nut to vibrate, so that the nut cannot be accurately dropped into the two clamping heads 11.

[0036] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the technical field according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model can make equivalent replacement or change, and all of them should be covered in the protection scope of the utility model.
