Description

Technical Field

[0001] The present invention belongs to the technical field of automobile parts production and processing, and particularly relates to a clamping device and a clamping method for automobile parts production and processing. Background Art

[0002] Automobile parts are the various units that make up the overall automobile parts processing and the products serving automobile parts processing. As the foundation of the automobile industry, automobile parts are essential factors to support the sustainable and healthy development of the automobile industry. Molds are various molds and tools obtained by injection molding, blow molding, extrusion, die casting, forging, smelting, stamping, etc. in industrial production. In short, a mold is a tool used to make formed articles. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the outer shape of the article by changing the physical state of the formed material, and some molds need to be clamped during the production and processing, and then surface processing is carried out on them; the existing processing devices for automobile parts production have relatively single functions, and it is not convenient to adjust the orientation of the parts, etc., which may affect the processing operation or processing accuracy of the parts. Summary of the Invention

[0003] The purpose of the present invention is to provide a clamping device and a clamping method for automobile parts production and processing in view of the deficiencies of the prior art. The clamping device can adjust the inclination and flipping angle of the parts according to needs, so as to facilitate the processing operation of the parts.

[0004] The purpose of the present invention is achieved as follows: A clamping device for automobile parts production and processing includes a frame. A synchronous clamping mechanism is arranged on the frame. The synchronous clamping mechanism includes a rotating frame. A guiding groove is arranged on the rotating frame along its length direction. An adjusting screw is arranged in the guiding groove. The two ends of the adjusting screw are respectively rotatably connected to the rotating frame. Guide blocks are respectively connected to the positions near the two ends of the adjusting screw. Clamping plates are respectively connected to the guide blocks. A positioning mechanism is arranged on the inner side surface of the clamping plate. The thread directions of the adjusting screw near the two ends are opposite. A flipping adjusting mechanism and a rotating adjusting mechanism are arranged between the rotating frame and the frame. An auxiliary clamping mechanism is connected to the lower surface of the clamping plate.

[0005] Further, the flipping adjusting mechanism includes a flipping frame. The bottom end of the flipping frame is rotatably connected to the top end of the frame through a hinge shaft. The hinge shaft is fixedly connected to the flipping frame and rotatably connected to the frame. A rotating driving mechanism A is connected to the hinge shaft. The rotating adjusting mechanism is connected to the flipping frame. The rotating driving mechanism A drives the flipping frame to rotate through the hinge shaft, so as to adjust the parts in the front-back direction.

[0006] Further, the rotation adjustment mechanism includes a horizontal rotating shaft fixed on the side of the rotating frame away from the clamping plate. The horizontal rotating shaft is rotatably connected to the flipping frame. A rotation driving mechanism B is connected to the horizontal rotating shaft.

The worm and worm gear transmission can achieve self-locking of the flipping frame and the rotating frame.

[0008] Further, horizontal pointers are respectively arranged at positions near the ends of the horizontal rotating shaft and the hinge shaft. Rotation scale indicating plates are respectively arranged around the horizontal rotating shaft on the flipping frame and around the hinge shaft on the machine frame.

An auxiliary support plate is threadedly connected to the lifting screw rod. The bottom end of the lifting screw rod is connected to a rotating motor. The rotating motor is fixed on the mounting plate. The mounting plate is fixedly connected to the clamping plate. By driving the lifting screw rod to rotate through the rotating motor, the height position of the auxiliary support plate relative to the positioning mechanism can be adjusted, so as to provide auxiliary support for the components.

[0010] Further, the positioning mechanism and the clamping plate are connected in a detachable manner, and different positioning mechanisms can be replaced according to the types, shapes and sizes of the components to fix the components.

[0011] A clamping method for automobile component production and processing includes the following steps: Step 1, rotate the adjustment screw rod to adjust the distance between the two clamping plates, and fix the components through the positioning mechanism; Step 2, adjust the height position of the auxiliary clamping mechanism, and provide auxiliary support and fixation for the components through the auxiliary clamping mechanism; Step 3, according to needs, adjust the orientation and position of the components respectively through the flipping adjustment mechanism and the rotation adjustment mechanism, so as to perform processing operations on the components.

[0012] The beneficial effects of the present invention: 1. The present invention is connected with a rotation adjustment mechanism on the fixing mechanism of automotive parts. Through the rotation adjustment mechanism, the parts can be driven to continuously rotate around the horizontal rotation axis, and the inclination angle of the axes of the two positioning mechanisms relative to the horizontal plane direction can also be adjusted as needed, so as to adjust the lateral orientation of the automotive parts.

[0013] 2. The present invention is equipped with a flipping adjustment mechanism on the fixing mechanism of automotive parts. Through the flipping adjustment mechanism, the inclination angle of the parts in the front - rear direction around the hinge axis can be adjusted, so as to meet the usage requirements for processing the parts at different positions.
