Description

Technical Field

[0001] This utility model relates to the field of automated production line technology, and in particular to a wedge clamping mechanism for supporting suspended workpieces during assembly on an assembly machine. Background Technology

[0002] The engine cylinder head contains numerous components such as camshaft cover locating pins, which are widely distributed. Due to the cylinder head's structure, the support positions cannot completely cover all component locations. To ensure a high assembly pass rate, the support positions must typically cover all component locations. Failure to do so introduces uncertainty, lowers the pass rate, and disrupts the production line's cycle time. It also increases the workload for workers, increasing the risk of missed components due to manual operation, inevitably leading to quality issues.

[0003] In view of the problems existing in the prior art, it is necessary to study and design a new type of wedge clamping mechanism for supporting suspended workpieces during assembly in an assembly machine, so as to overcome the problems existing in the prior art. Summary of the Invention

[0004] The existing support devices proposed in the above-mentioned prior art cannot fully support the various components of the engine cylinder head, which leads to a decrease in the pass rate, affects the production line's production rhythm, increases the labor intensity of rework and labor costs, and other technical problems. Therefore, a wedge clamping mechanism for supporting suspended workpieces during assembly is provided.

[0005] The technical means adopted in this utility model are as follows: A wedge clamping mechanism for supporting suspended workpieces during assembly by an assembly machine includes: a base plate mounted on the machine tool fixture base; Furthermore, a mounting plate is fitted to the bottom of the base plate via a support plate; Furthermore, a support block is mounted on the hinge mechanism at the front of the bottom end of the mounting plate; Furthermore, a low-pressure auxiliary support structure is mounted on the guide frame at the bottom center of the mounting plate; Furthermore, a feed cylinder is mounted on the mounting bracket at the rear bottom of the mounting plate; Furthermore, the output end of the feed cylinder is connected to the input end of the low-pressure auxiliary support structure, and the output end of the low-pressure auxiliary support structure is hinged to the support block. The extension and retraction of the output end of the feed cylinder drives the support block through the low-pressure auxiliary support structure to support the workpiece.

[0006] Furthermore, the feed cylinder is fixedly mounted on the rear end face of the mounting bracket by fixing screws; Furthermore, the cylinder rod fed into the cylinder passes through a through hole on the mounting bracket and connects to the low-pressure auxiliary support structure.

[0007] Furthermore, the low-pressure auxiliary support structure includes: a low-pressure auxiliary support and a connecting shaft; Furthermore, the low-pressure auxiliary support is fixedly installed on the front end face of the guide frame; Furthermore, the connecting shaft is installed in the guide hole of the guide frame, and its rear end is fixedly connected to the output end of the feed cylinder by a lock nut. Its front end passes through the low-pressure auxiliary support and is hinged to the support block by pin A. Furthermore, the feed cylinder drives the connecting shaft to move, thereby enabling the support block to support the workpiece.

[0008] Furthermore, the hinge mechanism includes: a support frame; Furthermore, the support frame is installed at the front of the bottom end of the mounting plate; Furthermore, the lower part of the support frame is hinged with a support block via a pin B; Furthermore, the support block is hinged to the front end of the connecting shaft via pin A. Furthermore, a spacer B is installed on each of the pins B on both sides of the support block to limit the left and right movement of the support block. Furthermore, a retaining ring A and a washer are fitted on both sides of the pin B on the outside of the support frame, and the retaining ring A and the washer fix the left and right limiting positions of the support block.

[0009] Furthermore, a spacer A and a retaining ring B are fitted on both sides of the pin A located on the outside of the support frame; Furthermore, spacer A limits the left and right movement of the hinge between the support block and the connecting shaft, and retaining ring B fixes the fiber.

[0010] Furthermore, adjusting shims A and B are fitted on the contact surface between the top of the base plate and the machine tool fixture base plate to adjust the levelness of the entire mechanism.

[0011] The working process of this utility model is as follows: This utility model employs a hinge mechanism, low-pressure auxiliary support, and feed cylinder; before wedging the workpiece, the workpiece needs to reach the positioning position. After the workpiece is positioned, the support block is sent to the wedging position by the feed cylinder to wed the workpiece.
