Abstract
Description
Technical Field
[0001] This utility model relates to the field of tapping machine technology, specifically a tapping machine for nut processing. Background Technology
[0002] A tapping machine is a specialized mechanical device used to machine internal threads on metal or other material workpieces. Its working principle involves the tapping assembly driving the tap to rotate and applying pressure, causing the tap to cut into a pre-drilled hole in the workpiece, thus forming the required internal thread. Tapping machines come in various types, such as manual, electric, and pneumatic tapping machines. Manual tapping machines are relatively simple to operate but have lower efficiency, making them suitable for small-batch production or maintenance scenarios. Electric tapping machines are powerful, fast, and efficient, and are widely used in industrial production. Pneumatic tapping machines use compressed air as a power source and offer advantages such as stepless speed regulation and flexible operation.
[0003] While tapping machines can clamp nuts of different specifications, the adjustment process can be cumbersome. When frequently switching between multiple specifications, the clamping components need to be constantly adjusted, which consumes time and effort and affects the production rhythm. Moreover, for some nuts with large dimensional deviations, the clamping adaptability may be insufficient, making it difficult to achieve the ideal clamping effect. This results in a certain risk of nut shaking during tapping, affecting the stability of tapping quality.
[0004] Therefore, a tapping machine for nut processing is proposed. Utility Model Content

[0027] Due to the current inconvenience in clamping nuts of different specifications, which affects the stability of tapping quality, please refer to [link / reference needed]. Figures 1-5 This utility model provides a technical solution: a tapping machine for nut processing, including a worktable 1, a tapping assembly 2 fixedly installed on the top surface of the worktable 1, a control console 3 installed on the left side of the tapping assembly 2, the control console 3 being fixedly connected to the worktable 1, a placement mechanism 4 installed below the front end of the tapping assembly 2, and an adjustment mechanism 5 installed below the placement mechanism 4.
[0028] The placement mechanism 4 includes a drive unit and a placement unit;
[0029] The adjustment mechanism 5 includes an adjustment section and a moving section.
[0030] The drive unit includes a mounting plate 41, a lifting frame 42 is provided above the mounting plate 41, and positioning plates 43 are fixedly provided on the bottom surfaces of both ends of the lifting frame 42. A positioning frame 44 is sleeved on the lower outer side of the positioning plate 43. The bottom surface of the positioning frame 44 is fixedly connected to the worktable 1, and the lower end of the positioning plate 43 is slidably connected to the inner wall of the positioning frame 44.
[0031] A hydraulic cylinder 45 is fixedly installed on the top surface of the mounting plate 41. The hydraulic cylinder 45 is located between the two positioning frames 44 on the left and right. The top surface of the output shaft of the hydraulic cylinder 45 is fixedly connected to the lifting frame 42. Multiple drive rods 46 are provided on both the front and rear sides of the hydraulic cylinder 45. The top surface of the drive rods 46 is fixedly connected to the lifting frame 42.
[0032] The placement part includes a connecting frame 47, and multiple connecting frames 47 are evenly arranged. The connecting frames 47 correspond to the adjacent drive rods 46. The bottom surface of the connecting frame 47 is fixedly connected to the mounting plate 41. A limit plate 48 is provided above the connecting frame 47. A placement frame 49 is fixedly provided on the top surface of the limit plate 48. A fixing rod is fixedly provided on the outer end of the placement frame 49. The lower end of the fixing rod is fixedly connected to the connecting frame 47. A lifting block 410 is provided between the connecting frame 47 and the limit plate 48. The bottom surface of the drive rod 46 is fixedly connected to the top surface of the adjacent lifting block 410.
[0033] The outer side of the lifting block 410 is hinged with a hinge frame 411, and six hinge frames 411 are evenly arranged. The other end of the hinge frame 411 is hinged with a moving rod 412.

[0035] Furthermore, in this embodiment, the output shaft of the hydraulic cylinder 45 extends and retracts, driving the lifting frame 42 to move up and down.

[0037] Example 2:
[0038] Please see Figures 1-5 Furthermore, based on Embodiment 1, the adjustment unit includes a fixed frame 51, the bottom surface of which is fixedly connected to the workbench 1. A sliding groove is provided on the inner wall of the fixed frame 51. A movable plate 52 is provided inside the fixed frame 51. The left and right ends of the movable plate 52 are located inside the sliding groove and are slidably connected to the inner wall of the sliding groove. A cylinder 53 is fixedly provided on the front of the fixed frame 51. The output shaft of the cylinder 53 passes through the fixed frame 51 and is fixedly connected to the movable plate 52.
[0039] The movable part includes a second fixed frame 54, the bottom surface of which is fixedly connected to the movable plate 52. A movable seat 55 is provided inside the second fixed frame 54, and the movable seat 55 is slidably connected to the inner wall of the second fixed frame 54. The top surface of the movable seat 55 is fixedly connected to the bottom surface of the mounting plate 41. A second cylinder 56 is fixedly installed on the left side of the second fixed frame 54, and the output shaft of the second cylinder 56 passes through the second fixed frame 54 and is fixedly connected to the movable seat 55.
[0040] Furthermore, in this embodiment, cylinder 53 is activated, and the output shaft of cylinder 53 extends and retracts, causing the movable plate 52 to slide back and forth in the sliding groove on the inner wall of the fixed frame 51. Since the bottom surface of the fixed frame 51 is fixedly connected to the worktable 1, the movement of the movable plate 52 realizes the position adjustment of the placement mechanism 4 in the front-back direction. Cylinder 56 is activated, and the output shaft of cylinder 56 extends and retracts, causing the movable seat 55 to slide on the inner wall of the fixed frame 54. Since the top surface of the movable seat 55 is fixedly connected to the bottom surface of the mounting plate 41, the movement of the movable seat 55 realizes the position adjustment of the placement mechanism 4 in the left-right direction.
[0041] Furthermore, in this embodiment, the adjusting part of the adjusting mechanism 5 drives the moving plate 52 to adjust its position forward and backward through the cylinder 1 53, and the moving part drives the moving seat 55 to adjust its position left and right through the cylinder 2 56, so that the placement mechanism 4 can flexibly adjust its position on the worktable 1 to tap the nuts in different placement racks 49, thereby improving the flexibility of the tapping machine.
[0042] In use, the output shaft of hydraulic cylinder 45 extends and retracts, driving the lifting frame 42 to move up and down. The drive rods 46 on both sides of hydraulic cylinder 45 also move synchronously with the lifting frame 42. When the drive rods 46 move up and down, they drive the lifting block 410 to move up and down. When the lifting block 410 moves up and down, it drives the hinge frame 411 to deflect. The hinge frame 411 drives the moving rod 412 to slide within the limit groove and the limit frame 413, thereby changing the position of the moving rod 412. As the position of the moving rod 412 changes, the fixing plate 414 moves within the connecting groove, which can clamp the nut placed on the placement frame 49. By holding or releasing the cylinder, cylinder 53 is activated, and the output shaft of cylinder 53 extends and retracts, causing the movable plate 52 to slide back and forth in the sliding groove on the inner wall of the fixed frame 51. Since the bottom surface of the fixed frame 51 is fixedly connected to the worktable 1, the movement of the movable plate 52 realizes the position adjustment of the placement mechanism 4 in the front-back direction. Cylinder 56 is activated, and the output shaft of cylinder 56 extends and retracts, causing the movable seat 55 to slide in the inner wall of the fixed frame 54. Since the top surface of the movable seat 55 is fixedly connected to the bottom surface of the mounting plate 41, the movement of the movable seat 55 realizes the position adjustment of the placement mechanism 4 in the left-right direction.
[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
