Description

Technical Field

[0001] The utility model relates to the technical field of automobile sheet metal inspection tool mold frames, in particular to a clamping mechanism of a mold frame for automobile sheet metal inspection tools. Background Art

[0002] The automotive sheet metal inspection fixture mold base is a special equipment that combines the inspection fixture, which is a fixture used to inspect the quality and size of parts such as stamping parts, with the characteristics of the mold base. It integrates the inspection function of the inspection fixture with the positioning and support functions of the mold base to ensure the dimensional accuracy and quality requirements of sheet metal parts during the production process.

[0003] A Chinese patent, publication number CN214407386U, discloses a mold frame for an automotive sheet metal inspection fixture. The mold frame comprises a base plate with side clamping mechanisms symmetrically mounted on the left and right sides of the upper surface of the base plate. A buffer block is mounted in the middle of the upper surface of the base plate. Several wear-resistant blocks are removably mounted on the upper end of the buffer block, and the lower end of the buffer block is connected to a buffer mechanism within the base plate. Mounting slots are symmetrically positioned on the front and rear sides of the upper surface of the base plate, each containing a screw rod. An upper clamping mechanism is mounted on a slider mounted on the screw rod. This utility model is adaptable to inspection fixtures of varying sizes and effectively secures them. It also provides a buffer when placing the inspection fixture, preventing collisions.

[0004] As mentioned above, the patent provides an automobile sheet metal inspection fixture mold frame, which can be used for inspection fixtures of different specifications and can effectively fix the inspection fixtures; at the same time, it can provide a buffer when placing the inspection fixture to avoid collision of the inspection fixture. However, for the inspection fixture mold frame, not only its size will be different, but the height of the required inspection fixture mold frame will also be different according to different automobile parts. Since it cannot adjust the height of the clamping point, it is impossible to clamp the center of gravity of the inspection fixture mold frame. When the mold frame is not clamped at the center of gravity or is clamped improperly, the stability of the entire mold frame system will be significantly reduced. When bearing external loads, that is, the load of the mold, the mold frame is prone to tilting, shaking or even collapse. Therefore, the overall clamping effect needs to be improved.

The positioning threaded rod 12 is slidably connected with the fixed clamping plate 3. When working, the sliding positioning threaded rod 12 drives the positioning clamping plate 13 to slide on the top of the placement slot 2, thereby further supporting and limiting the inspection tool mold frame, and then the locking bolt 14 is rotated, and a T-shaped snap ring 16 is fixed on one side of the locking bolt 14, and a T-shaped circular groove 15 is opened on the surface of one side of the fixed clamping plate 3, so that the locking bolt 14 can rotate on the surface of the fixed clamping plate 3, and can rotate according to the surface thread of the positioning threaded rod 12 after its rotation, thereby driving the fixed clamping plate 3 to rotate.
