[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A positioning device for processing automotive parts includes a placement table with multiple clamping seats evenly arranged on it. A movable adjustment structure is provided between the outer side of each clamping seat and the placement table. An adjustment groove is formed on the inner surface of each clamping seat. A clamping block is slidably disposed within the adjustment groove and is fitted with an elastic compensation structure. A clamping plate is provided on the surface of each clamping block. A pressure detection element is provided between the clamping plate and the clamping block. A mounting base is provided below the placement table.

The sealing plug is disposed inside the clamping block, and the output end of the air pump is provided with an air supply hose. The air supply hose is connected to the inner wall of the adjustment groove. When clamping and fixing automotive parts, after the automotive parts are initially fixed by the clamping seat, the air pump can be started. Under the action of the air pump, the airflow is delivered to the adjustment groove through the air supply hose, and under the action of the sealing plug, the clamping block is driven to move outward with the clamping plate, thereby further improving the clamping effect of automotive parts during processing.

[0010] The present invention is further configured such that the rotation adjustment structure includes a rotation motor, the mounting base has a mounting cavity, the rotation motor is located in the mounting cavity, the bottom end of the placement platform is provided with a mounting shaft, the mounting shaft is mounted on the mounting base through a bearing and is connected to the rotation motor for transmission. When the rotation motor is started, the mounting shaft can be controlled to drive the placement platform to rotate, thereby realizing the rotation adjustment of the placement platform, and thus realizing the flexible adjustment of the processing angle during the processing of automotive parts.

[0011] The present invention is further configured such that an inner limiting edge and an outer limiting edge are provided in the adjusting groove, and an engaging edge is provided at the inner end of the clamping block. The engaging edge is located between the inner limiting edge and the outer limiting edge.

This can improve the positioning and clamping effect of the clamping seat and clamping plate on the automotive parts during processing. The outer limiting edge can limit the clamping block from disengaging from the adjusting groove, thereby improving the clamping effect of the clamping plate on the automotive parts during processing.

[0012] The present invention is further configured such that the movable adjustment structure includes a fixed base, an electric push rod is provided on the fixed base, and a clamping seat is provided at the output end corresponding to the electric push rod. When the electric push rod is activated, the movement of the clamping seat can be controlled by the electric push rod, thereby realizing the stable clamping and fixing of the automotive parts on the placement table, and realizing the stable clamping and positioning of the automotive parts on the placement table during processing.

[0013] The present invention is further configured such that the horizontal lateral movement structure includes a movable frame, the movable frame being slidably sleeved on the worktable, a first drive screw being provided on the worktable, and a first motor being provided in conjunction with the first drive screw, the movable frame being threaded onto the first drive screw, the first motor being started, and the first drive screw being controlled to run, causing the movable frame to move horizontally on the worktable, thereby realizing the horizontal lateral movement of the placement platform on the worktable, and thus realizing the adjustment of the horizontal lateral movement positioning position of the automotive parts during the processing.

[0015] The present invention is further configured such that limit rods are provided on both sides of the first drive screw and the second drive screw, and the movable frame and the mounting seat are slidably sleeved on the corresponding limit rods. The limit rods can limit the movement of the movable frame on the worktable and the movement of the mounting seat on the movable frame, thereby improving the movement stability.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a positioning device for processing automotive parts, which has the following advantages:

[0018] 1. This utility model achieves dynamic adaptive clamping of automotive parts through the synergistic effect of an elastic compensation structure (air pump + sealing plug driving the clamping block to move) and a pressure detection component. The clamping force can be automatically adjusted and compensated according to the size tolerance of the parts, avoiding deformation or loosening caused by over-clamping.

[0019] 2. At the same time, the rotation adjustment structure (rotation motor + mounting shaft) supports multi-angle machining adjustment.

When the second motor 24 is started, the second drive screw 23 can be rotated, thereby enabling the mounting seat 7 to achieve horizontal longitudinal movement adjustment on the moving frame 20. This, in turn, enables the horizontal longitudinal movement adjustment of the placement seat located on the mounting seat 7, allowing for flexible adjustment of the horizontal longitudinal position of automotive parts during clamping and positioning.

[0038] Furthermore, limit rods 25 are provided on both sides of the first drive screw 21 and the second drive screw 23.
