Description

A machining equipment for milling the upper and lower planes of the first and second gear shift forks

technical field

The technical field of mechanical processing equipment of the present invention specifically relates to a processing equipment for milling the upper and lower planes of a shift fork for first and second gears.

Background technique

The first and second gear shift forks shown in Figure 5 and Figure 6 are one of the important parts of the automobile transmission. During the process, a three-jaw chuck is usually used to clamp the round shaft of the first and second gear shift forks, and then a horizontal milling machine is used for processing. Since the upper and lower planes of the first and second gear shift forks have to be milled, two times of clamping and alignment are required, which is very troublesome, resulting in low machining accuracy of parts and low production efficiency.

Contents of the invention

In view of the above technical problems, it is planned to provide a machining equipment for milling the upper and lower planes of the first and second gear shift forks. After the workpiece is quickly clamped, the vertical milling machine is used to finish the upper and lower planes of the shift fork. The operation is convenient and fast, and one time Two workpieces can be processed at the same time, improving production efficiency and processing accuracy.

For this reason, the technical solution adopted in the present invention is: a kind of machining equipment for milling the upper and lower planes of the first and second gear shift forks, comprising a tooling base plate (1) and a vertical milling machine (10), characterized in that: the tooling base plate ( 1) is provided with two vertical cylinders (2) and a vertical plate (3) extending left and right, the middle part of the top of the vertical plate (3) is provided with a milling cutter disc relief gap (3a), two The vertical cylinders (2) are spaced left and right in the rear of the vertical plate (3), and the vertical plate (3) is provided with a number of vertical cylinders (2) equal to and corresponding to the position of the pressure rod give way gap (3b), each Each vertical cylinder (2) is correspondingly provided with a compression link (4), and the rear end of the compression link (4) is hinged on the piston rod top of the corresponding vertical cylinder (2), and the compression link The front end of (4) is provided with a compression hook (4a) extending downwards, and the middle part of the compression link (4) passes through the corresponding compression bar relief gap (3b) and is hinged with the vertical plate (3) Together;

When the lower plane of the shift fork is supported by the right support block (7), the pressing hook head (4a) on the right side is pushed by the vertical cylinder (2) to just press on the top of the first and second shift forks. After the shift fork is rotated 180° counterclockwise, put the round hole of the first and second shift fork on the left set cylinder (5), and at the same time, the fork of the first and second shift fork faces right and supports the shift fork through the left support cylinder (6) When the root of the fork is on the circular arc surface, the pressing hook (4a) on the left side is pushed by the vertical cylinder (2) to just press on the top of the first and second shift forks, and is located on the top of the first and second shift forks on the right. The plane is coplanar with the lower plane of the first and second shift forks on the left;

The left set cylinder, left support cylinder and left compression hook are used to clamp and position the workpiece before processing the lower plane. Plane, the right supporting block, the right sleeve cylinder and the pressing hook on the right side are used to process the upper plane after the workpiece is clamped and positioned. First place the workpiece to be processed, put the round hole of one of the first and second shift forks (the lower plane has been processed) on the right set cylinder, and make the fork mouth face to the left and pass through the right support block and the right side. Clamp and position the hook head, and at the same time rotate a new first and second gear fork counterclockwise 180°, put the round hole of the first and second gear fork on the left set cylinder, and the fork of the first and second gear fork faces right And it is clamped and positioned by the left support cylinder and the compression hook on the left side. Since the lower plane of the first and second gear shift forks on the right has been processed, it can be directly supported by the right support block, while the lower plane of the first and second gear shift forks on the left is a rough surface, so it is supported on the fork opening by the left support cylinder Root arc. Since the two first and second shift forks are oppositely arranged, and the upper plane of the first and second shift fork on the right is coplanar with the lower plane of the first and second shift fork on the left, the milling cutter head of the vertical milling machine is just located on the two sides. Between the first and second shift forks, the upper plane of the first and second shift forks on the right side and the lower plane of the first and second shift forks on the left are processed by the milling cutter at one time. After the processing is completed, the piston rods of the two vertical cylinders and the milling cutter head of the vertical milling machine are returned, and the first and second gear shift forks on the right are removed, and the first and second gear shift forks on the left are rotated 180° counterclockwise. Put it into the clamping position on the right to continue the processing of the upper plane, and then put a new workpiece into the clamping position on the left to process the lower plane.

As the preference of the above scheme, the left sleeve cylinder (5) and the right sleeve cylinder (8) are equal in length, the rear end surfaces of the left support cylinder (6) and the right support block (7) are coplanar, and the left support cylinder (6) Longer than the left and right suit cylinders (5,8). Increase the length of the left support cylinder and the right support block to improve the support strength.

The beneficial effect of the present invention: the concept is novel, the design is ingenious, the workpiece is clamped and positioned by the positioning tool, and then the upper and lower planes of the shift fork are finished with a vertical milling machine, and the upper plane of one workpiece and the lower plane of another workpiece can be completed at one time.
