Description

Technical Field

[0001] The utility model relates to a clamping head suitable for automobile yoke processing and belongs to the technical field of automobile yoke processing equipment. Background Art

[0002] The automobile yoke is a commonly used component of the automobile steering system. It has an integrated structure and includes a base 1 and a fork body 2. The front end of the base 1 is a flat structure, and the rear end of the base 1 is a curved structure. At present, under the trend of automated processing, a robot arm is often used in conjunction with a parallel cylinder to complete the grasping and transfer of the yoke. Although the existing yoke transfer method can meet the needs of production and use to a certain extent, the automobile yoke has the characteristics of structural abnormality. Using the commonly used parallel cylinder to clamp the workpiece has the following problems:

[0003] First: The parallel cylinder has inaccurate positioning, which causes the workpiece to often deviate from the installation position.

[0004] Second: After the robot arm transfers the workpiece to the specified position through the parallel cylinder, when the parallel cylinder releases the workpiece, the workpiece is out of contact with the parallel cylinder under the action of gravity, and the workpiece is often not pushed into place, resulting in transfer failure.

[0005] Therefore, it is necessary to develop a new clamping head to solve the above problems when the existing robot arm transfers the yoke. Summary of the invention

[0006] The utility model aims to provide a clamping head which has a compact structure and an ingenious design and is suitable for automobile yoke processing to solve the problem of low transfer success rate when the existing mechanical arm transfers the yoke.

[0009] The inner side of the clamping block A is a planar structure; the inner side of the clamping block B is provided with a V-shaped positioning opening.

[0010] The pushing plate is an integrated structure; it includes a main board and a support board; four groups of support boards are symmetrically arranged at the upper and lower ends of the main board; guide sliding holes are arranged on the support boards; the support boards are slidably connected with the guide pins through the guide sliding holes.

[0011] Two groups of positioning through holes are symmetrically arranged on the main board.

[0022] The clamping head suitable for automobile yoke processing includes a parallel cylinder 3, a clamping block A4, a clamping block B5, a push plate 6, a push spring 10 and an assembly ring 7 (see the attached manual). Figure 1 ).

[0023] The parallel cylinder 3 is equipped with a clamping block A4 and a clamping block B5 (see the appendix of the manual). Figure 1 ). The parallel cylinder 3 is an externally purchased device. When the parallel cylinder 3 is working, it can drive the clamping block A4 and the clamping block B5 to move closer to each other or separate from each other.

[0024] The inner side of the clamping block A4 is a flat structure; the inner side of the clamping block B5 is provided with a V-shaped positioning opening 11 (see the attached manual Figure 2 ). The purpose of setting the clamping block A4 and the clamping block B5 in this way is to make the plane of the clamping block A4 fit and connect with the plane structure of the workpiece base 1 when the clamping block A4 and the clamping block B5 clamp the workpiece during operation; the V-shaped opening of the clamping block B5 fit and connect with the arc surface structure of the workpiece base 1. This avoids the problem of unstable clamping caused by the clamping block A4 and the clamping block B5 not fitting with the workpiece surface when they are in other states.

[0025] A push plate 6 is provided between the clamping block A4 and the clamping block B5; an assembly ring 7 is provided at the bottom of the parallel cylinder 3 above the push plate 6 (see the attached manual). Figure 1 ). The assembly ring 7 includes two sets of connecting half rings; the ends of the two sets of connecting half rings are connected to each other by locking bolts (not shown in the drawings of the specification). The purpose of such a setting is to enable the assembly ring 7 to be quickly installed on the parallel cylinder 3 by assembling the two sets of connecting half rings.

[0026] The assembly ring 7 is provided with a plurality of guide pins 8; the guide pins 8 are slidably connected with the push plate 6; a limit flange 9 is provided on the guide pins 8 below the push plate 6; a push spring 10 is sleeved on the guide pins 8 above the push plate 6 (see the attached manual). Figure 1 and 3 The purpose of setting the guide pin 8 and the push spring 10 is to make the push plate 6 always have a tendency to move downward under the action of the elastic force of the push spring 10 during operation. The limiting flange 9 prevents the push plate 6 from being out of contact with the guide pin 8.

[0027] The push plate 6 is an integrated structure; it includes a main board 12 and a support plate 13; four groups of support plates 13 are symmetrically arranged at the upper and lower ends of the main board 12; guide sliding holes 14 are arranged on the support plates 13; the support plates 13 are slidably connected to the guide pins 8 through the guide sliding holes 14. Two groups of positioning through holes 15 are symmetrically arranged on the main board 12 (see the attached manual Figure 6 The aperture of the positioning through hole 15 is consistent with the shape of the workpiece fork body 2, so that the fork body 2 of the workpiece can be inserted into the positioning through hole 15 of the main board 12 during operation, thereby achieving the purpose of positioning the workpiece through the positioning through hole 15.

[0028] When the clamping head is working, the robot arm will move downward after aligning the clamping head with the workpiece, so that the positioning through hole 15 on the push plate 6 is plugged and connected. During the process of continuing to move downward, the upper end surface of the workpiece base 1 will squeeze the push plate 6, so that it overcomes the elastic force of the push spring 10 and moves upward. Then, the clamping block A4 and the clamping block B5 will clamp the base 1 of the workpiece under the action of the parallel cylinder 3. After the clamping block A4 and the clamping block B5 clamp the workpiece, the robot arm drives the workpiece to the specified position, and the clamping block A4 and the clamping block B5 will release the workpiece. At this time, the workpiece will be pressed by the elastic force of the push plate 6, so as to avoid the problem of displacement when the workpiece is suddenly loosened. Then, during the process of the robot arm driving the clamping head to move, the pressing force of the push plate 6 will gradually decrease and eventually break away from the workpiece, and then the clamping head can enter the next working cycle.

[0029] The clamping head suitable for automobile yoke processing has a compact structure and ingenious design. It can be doubly positioned by the clamping block B5 and the pushing plate 6, and the pushing plate 6 has the function of pushing the workpiece, thereby solving the problem of low transfer success rate when the existing robot arm transfers the yoke, and is particularly suitable for the needs of automobile yoke processing and transfer.
