Description

Technical Field

[0001] The utility model relates to the technical field of machining production equipment, in particular to a machining multi-station fixture. Background Art

[0002] Machining refers to the process of modifying a workpiece's dimensions or properties through mechanical means. Based on the differences in machining methods, it can be categorized into two types: cutting and press machining. Both cutting and press machining require a fixture to secure the workpiece during the machining process.

[0003] According to the invention patent application with publication number CN118288058A and publication date July 5, 2024, a machining fixture is disclosed, comprising a base, with columns 1 and 2 mounted on the top of the base, a fixed column disposed between columns 1 and 2, a clamping mechanism 1 disposed between columns 1 and 2, and a clamping mechanism 2 disposed between the fixed column and column 2. When the dual-axis motor within the transmission assembly is in operation, the transmission mechanisms 1 and 2 can simultaneously drive the hydraulic cylinder and the pneumatic cylinder 3 to rotate vertically, thereby adjusting the vertical angle of the workpieces on the clamping mechanisms 1 and 2. Its main technical effect is to facilitate external devices to perform machining operations on other surfaces of the two workpieces. The transmission mechanisms 1 and 2 can control whether the bevel gears 2 and 3 mesh with the bevel gears 1 and 4 through the electric cylinders therein. The benefit of this control is that when the dual-axis motor is in operation, the rotation of block or tubular workpieces can be independently controlled, thereby expanding the scope of application of the device and meeting the different usage needs of workers.

[0004] During the machining process, it is usually necessary to process multiple workpieces. When clamping the workpiece, the existing fixture can only clamp one workpiece at a time, and the machining efficiency is low. Therefore, a machining multi-station fixture is proposed to solve the problem that the fixture in the existing technology can only clamp one workpiece at a time and the machining efficiency is low.

The clamping unit includes a clamping seat, a clamping block and a pre-clamping plate. The clamping seat is fixedly connected to the base, and the clamping block is transmission-connected to the driving unit.

[0021] Specifically, such as Figure 1 As shown, three mounting surfaces are provided on the outer wall of the base 1. Preferably, the three mounting surfaces are distributed in a circular array on the side wall of the base 1. The number of clamping units 2 is also several, and the clamping units 2 are distributed in a circular array on the side wall of the base 1. Specifically, two clamping units 2 are symmetrically provided on one of the mounting surfaces. Specifically, the clamping unit 2 includes a clamping seat 21, a clamping block 22 and a pre-clamping plate 23, as shown in FIG. Figure 2 As shown, the clamping seat 21 is a "U"-shaped structure. The clamping seat 21 is fixedly installed on the outer wall of one side of the base 1. There are two clamping blocks 22. Both clamping blocks 22 are slidably connected to the inside of the clamping seat 21. Figure 2As shown, the top of the clamping block 22 is a "U"-shaped structure, and a guide rod 24 is fixedly installed on the outer wall of the pre-clamping plate 23. The pre-clamping plate 23 is slidably connected to the "U"-shaped structure at the top of the clamping block 22 through the guide rod 24. Furthermore, an abutment block is fixedly provided on the outer wall of the guide rod 24, and an elastic unit is provided between the abutment block and the inner wall of the "U"-shaped structure of the clamping block 22. Specifically, the elastic unit is a compression spring, which can drive the guide rod 24 to move between the two clamping blocks 22 through the elastic unit. The pre-clamping plates 23 arranged inside the clamping blocks 22 on both sides can be moved toward the center of the clamping seat 21 through the elastic unit, thereby achieving pre-clamping of the workpiece.

[0022] As an embodiment provided by the present invention, the driving unit 3 includes a rotating rod 31, a driving rod 32, a transmission rod 33, a driving gear 34 and a transmission gear 35. Specifically, a mounting groove is provided on the top of the base 1, the rotating rod 31 is rotatably connected to the inside of the mounting groove, one end of the driving rod 32 is slidably connected to the rotating rod 31, and the circumferential outer wall of the driving rod 32 is threadedly connected to the base 1. As an embodiment provided by the present invention, the number of driving gears 34 is two, and the two driving gears 34 are fixedly mounted on the outer wall of the rotating rod 31. The number of transmission rods 33 is adapted to the number of clamping units 2, and the transmission gear 35 is provided. One end of the movable rod 33 is rotatably connected to the inside of the clamping seat 21, and one end of the transmission rod 33 passes through and extends into the inside of the mounting groove. The transmission gear 35 is fixedly installed at one end of the transmission rod 33 located inside the mounting groove. The transmission gear 35 is meshed with the driving gear 34. The rotating rod 31 is rotated by manual driving. The rotation of the rotating rod 31 synchronously drives the driving rod 32 to keep rotating, and the driving gear 34 is synchronously driven to keep rotating. The rotation of the driving gear 34 drives the transmission gear 35 meshed with it to rotate. As an embodiment provided by the utility model, the driving gear 34 and the transmission gear 35 are both bevel gears.

[0023] Further, such as Figure 3 As shown, the drive unit 3 also includes a linkage gear 36 and a linkage gear rod 37. The number of the linkage gears 36 is adapted to the number of the transmission rods 33. The linkage gear 36 is fixedly installed at one end of the transmission rod 33 located inside the clamping seat 21.

[0025] Working principle:

[0026] When a workpiece needs to be clamped, the operator holds the workpiece to be clamped and places the workpiece between the two pre-clamping plates 23. At this time, the elastic unit drives the two pre-clamping plates 23 to pre-clamp the workpiece on the clamping seat 21.

[0027] Then pre-clamp the workpiece on all the clamping seats 21;

[0028] Then, all the workpieces need to be completely fixed to the clamping seat 21, and a wrench is used to drive the rotating rod 31 to keep rotating. Since one end of the rotating rod 31 is slidably connected to the driving rod 32, when the rotating rod 31 keeps rotating, the driving rod 32 can be driven to keep rotating synchronously.

[0029] When the driving rod 32 keeps rotating, the driving gear 34 on the outer wall of the driving rod 32 is synchronously driven to keep rotating, and then the transmission gear 35 is driven to keep rotating through the rotation of the driving gear 34, and the rotation of the transmission gear 35 further drives the transmission rod 33 and the linkage gear 36 installed on the transmission rod 33 to keep rotating, and finally drives the linkage gear rod 37 that keeps meshing with the linkage gear 36 to keep sliding in the clamping seat 21, driving the clamping block 22 to keep moving toward each other, and finally completely fixing the workpiece and the clamping seat 21.

[0030] The elastic coefficient of the elastic unit mentioned in this article meets the technical requirements of the technical solution of the present utility model.

[0031] Those skilled in the art will appreciate that other similar connection methods can also implement the present invention, such as welding, bonding, or screwing.

It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
