Description

A quick-change fool-proof fixture

Technical Field

The utility model belongs to the technical field of clamps, and more specifically, particularly relates to a fast-reversing fool-proof clamp.

Background Art

The tooling fixture is an important component to ensure the quality and production efficiency of parts in the process of parts manufacturing. Most of them use single-process special fixtures as the main one, and set a mechanical fool-proof structure to prevent the parts from having an incorrect clamping state in this process. When changing the process, the fixture needs to be replaced and re-debugged. Among them, China Patent No.: CN202220879986.4 provides a quick reversing fool-proof fixture, which relates to the field of fixture technology, including a base seat, circular bayonet ports are respectively arranged on both sides of the outer wall of the base seat, a cylinder is installed inside the circular bayonet, and the output ends of the two cylinders are respectively connected to corner pressure blocks, and a transition plate is connected between the corner pressure blocks and the base seat, and the transition plate includes a plate body, a semicircular notch and a locating pin. Semicircular notches are respectively arranged on both sides of the outer wall of the plate body, and a plurality of chucks are horizontally installed on one side of the outer wall of the transition plate. The chuck includes a fixture body, a jack and a mounting hole. A mounting hole is arranged on one side of the inner side of the chuck, and an infrared sensor is installed on one side of the inner side of the mounting hole. An interlaced locating pin is arranged on one side of the outer wall of the plate body, and one end of the locating pin extends to one side of the base seat respectively. The utility model has a reasonable structure and is easy to install, thus achieving more efficient loading and unloading work.

Based on the above, the inventors have found the following problems: the above patent has a relatively good effect on parts loading and unloading, but the chuck 3 cannot be fixed during the rapid rotation process after the parts are clamped. When processing some special parts, deviations are likely to occur, which will cause inconvenience to the staff.

Therefore, in view of this, the existing structure and defects are studied and improved, and a quick-reversing anti-fool clamp is provided, in order to achieve a more practical purpose.

Through the cooperation between the bolt and the sliding wheel, when the staff needs to adjust the chuck at multiple angles, they can loosen the sliding wheel by turning the bolt, and then the circular rotating block can be rotated, thereby driving the chuck to rotate at multiple angles. When it is rotated to an appropriate angle, the bolt can be turned again to utilize the damping between the sliding wheel and the circular fixed block, so that the bolt can be rotated and the circular rotating block can be pressed tightly against the circular fixed block, so that multi-angle adjustment can be completed and fixed. The operation steps are very simple, which indirectly brings convenience to the staff.

Through the design of the latch teeth, the fixing efficiency of the fitting part between the circular fixed block and the circular rotating block can be improved to avoid shaking during subsequent use or processing of the parts. This design greatly increases the practicality.
