Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0026] Specific examples are given below.

[0027] See also Figure 1 - Figure 7The utility model provides a nut tapping machine, comprising a workbench 1; a slide groove 25 is provided on the workbench 1; the slide groove 25 is provided with three groups, which are respectively provided on both sides and the middle of the workbench 1; a placing table 4 is slidably connected in the slide groove 25; a clamping box 23 is fixedly connected at the side walls on both sides of the workbench 1 corresponding to the slide groove 25; a top plate 24 is fixedly connected to the top of the clamping box 23; a return spring 31 is fixedly connected to the side wall of the top plate 24 inside the clamping box 23; a slide plate 32 is fixedly connected to the end of the return spring 31; the slide plate 32 is slidably connected in the clamping box 23; the slide plate 32 is away from the clamping box 23 A clamping spring 33 is fixedly connected to the side wall at the reset spring 31; a clamping block 34 is fixedly connected to the end of the clamping spring 33; a clamping groove 26 is provided on the side wall of the placing table 4 at the clamping block 34; a sliding column 30 is fixedly connected to the side wall of the slide plate 32 away from the clamping spring 33; the sliding column 30 is arranged through the top plate 24; during operation, in order to overcome the long-term accumulation of waste chips in the fixed seat in the prior art, which affects the clamping effect of the workpiece and thus affects the production quality of the workpiece, when working, first insert the placing table 4 into the sliding groove 25 provided on the workbench 1, and slide in the sliding groove 25. The edge of the placement table 4 will abut against the clamping block 34 in the clamping box 23. After the abutment, the placement table 4 will compress the clamping block 34 into the clamping box 23, and then the placement table 4 continues to slide in the slide groove 25 until the clamping groove 26 opened on the side wall of the placement table 4 is in a parallel position with the clamping block 34. After being in the parallel position, the clamping spring 33 in the clamping box 23 rebounds and bounces the clamping block 34 into the clamping groove 26. At this time, the placement table 4 cannot be pulled out of the slide groove 25 after being clamped by the clamping block 34. After the work is completed, a lot of waste chips will remain on the placement table 4. At this time, the staff can pull the sliding column 30 in the clamping box 23 When the slide post 30 is pulled, the slide post 30 drives the slide plate 32 to move toward the top plate 24. During the movement, the return spring 31 above the slide plate 32 will be squeezed, and the clamping block 34 will be retracted into the clamping box 23 again. After retraction, the clamping block 34 will be disengaged from the clamping groove 26. At this time, the placement table 4 is out of the restriction and can be slid out of the slide groove 25 again. After the placement table 4 is taken out, the return spring 31 rebounds and the clamping block 34 can be rebounded to the outside of the clamping box 23 again, waiting for the next clamping. The removed placement table 4 can be cleaned. After cleaning, the placement table 4 can be reinserted into the workbench 1 and wait for the next work.

[0028] Further, such as Figure 1 and Figure 3As shown, the surface of the placement table 4 is fixedly connected with a fixed base 5; the fixed base 5 is provided with three groups; the fixed base 5 is fixedly connected with a fixed bottom plate 8 and a fixed plate 6; the side wall of the fixed plate 6 is rotatably connected with a fixing bolt 7; the end of the fixing bolt 7 is rotatably connected with a clamping plate 9 near the fixed bottom plate 8; the side wall of the fixed bottom plate 8 is fixedly connected with an anti-slip pad 10. During work, after the placement table 4 is installed on the workbench 1, the staff can place the nut on the fixed base 5, and then drive the fixing bolt 7 to rotate. During rotation, the clamping plate 9 at the end of the fixing bolt 7 will move toward the fixed bottom plate 8, thereby clamping the nut, and tapping work can be performed after clamping.

[0029] Further, such as Figure 1 As shown, the surface of the workbench 1 is fixedly connected with a bridge frame 20; the top of the bridge frame 20 is fixedly connected with a bridge plate 16; the side wall of the bridge plate 16 is rotatably connected with a bidirectional screw rod 15; the bidirectional screw rod 15 is threadedly connected with a moving block 18; the side wall of the moving block 18 is fixedly connected with a connecting plate 14; the bottom of the connecting plate 14 is fixedly connected with a telescopic cylinder 13; the end of the telescopic cylinder 13 is fixedly connected with a tapping motor 12; the bottom of the tapping motor 12 is rotatably connected with a tapping head 11; the tapping head 11 is arranged above the fixed base 5; the side wall of the bridge plate 16 is provided with a limiting groove 17 at the bidirectional screw rod 15; the moving block 1 8 One end is slidably connected in the limit groove 17. During operation, after the nut is fixed on the placement table 4, the bidirectional screw rod 15 rotates to drive the moving block 18 to move in translation. During the translation, the tapping head 11 set on the connecting plate 14 can be driven to reach above the nut, and then the telescopic cylinder 13 drives the tapping head 11 to descend and reach the nut. The tapping motor 12 drives the tapping head 11 to rotate to perform the tapping work. When the moving block 18 moves, the moving block 18 can be limited by the limit groove 17. One end of the moving block 18 is slidably connected in the limit groove 17. During the movement, the limit groove 17 can prevent the moving block 18 from deviating during movement.

[0030] Further, such as Figure 6 As shown, bottom grooves 27 are provided in the bottom of the slide grooves 25 on both sides of the workbench 1; telescopic springs 28 are fixedly connected to the side walls of the bottom grooves 27; telescopic bottom plates 29 are fixedly connected to the ends of the telescopic springs 28; the telescopic bottom plates 29 are adapted to the size of the bottom grooves 27. During operation, when the placement table 4 is slidably connected in the slide grooves 25 and after being clamped, the bottom of the placement table 4 will touch the telescopic bottom plates 29 in the bottom grooves 27, thereby compressing the telescopic bottom plates 29 into the bottom grooves 27. When the staff uses the sliding column 30 to retract the clamping block 34 into the clamping box 23, the telescopic bottom plates 29 rebound through the telescopic springs 28, and the placement table 4 is ejected during the rebound, thereby cooperating with the staff to take out the placement table 4.

[0031] Further, such as Figure 1 As shown, the end of the sliding column 30 is fixedly connected with a pull rod 21; the pull rod 21 is U-shaped; an anti-skid sleeve 22 is sleeved on the pull rod 21; the side wall of the bridge plate 16 is fixedly connected with a moving motor 19 corresponding to the bidirectional screw rod 15; the bidirectional screw rod 15 is driven by the moving motor 19. When working, the pull rod 21 is fixedly connected to the end of the sliding column 30, and is used to connect the sliding columns 30 in two groups of snap-in boxes 23. Pulling the pull rod 21 can drive the sliding column 30 to rise, and the anti-skid sleeve 22 can prevent slipping when pulling the pull rod 21, and the moving motor 19 can drive the bidirectional screw rod 15 to rotate, thereby driving the moving block 18 to move horizontally.

[0032] Further, such as Figure 2 As shown, the bottom of the workbench 1 is fixedly connected to a supporting leg 2; the supporting leg 2 is arranged at the four corners of the bottom of the workbench 1; the bottom of the supporting leg 2 is fixedly connected to a rubber pad 3. When working, the workbench 1 may shake, the supporting leg 2 can alleviate the shaking, and the rubber pad 3 can prevent slipping during shaking.

[0033] Working principle: In order to overcome the problem in the prior art that waste chips are accumulated in the fixed seat for a long time and affect the clamping effect on the workpiece, thereby affecting the production quality of the workpiece, when working, the placement table 4 is first inserted into the slide groove 25 opened on the workbench 1, and slides in the slide groove 25. During the sliding process, the edge of the placement table 4 will abut against the clamping block 34 in the clamping box 23. After abutting, the placement table 4 compresses the clamping block 34 into the clamping box 23, and then the placement table 4 continues to slide in the slide groove 25 until the clamping groove 26 opened on the side wall of the placement table 4 is in a parallel position with the clamping block 34. After being in the parallel position, the clamping spring 33 in the clamping box 23 rebounds and bounces the clamping block 34 into the clamping groove 26. At this time, the placement table 4 cannot be pulled after being clamped by the clamping block 34. After the work is completed, a lot of waste chips will remain on the placement table 4. At this time, the staff can pull the sliding column 30 in the card box 23. When pulling the sliding column 30, the sliding column 30 drives the slide plate 32 to move toward the top plate 24. During the movement, the return spring 31 above the slide plate 32 will be squeezed, and the card block 34 will be retracted into the card box 23 again. After retraction, the card block 34 will be disengaged from the card slot 26. At this time, the placement table 4 is out of the restriction and can be slid out of the sliding groove 25 again. After the placement table 4 is taken out, the return spring 31 rebounds and the card block 34 can be rebounded to the outside of the card box 23, waiting for the next card connection, and the removed placement table 4 can be cleaned. After cleaning, the placement table 4 is reinserted onto the workbench 1 and waits for the next work.
