A self-adaptive adjustable fixture for processing aluminum products

Abstract

The invention discloses a self-adaptive adjusted fixture for aluminum product machining; and the fixture preferably realizes positioning and pressing of aluminum product workpieces, and can control the pressing force to the aluminum product workpieces to prevent damage to the workpieces. The fixture comprises a base plate; a slide block is arranged above the base plate; a screw rod is inserted inthe slide block; a bulb body is arranged at the right end of the screw rod; a pressing block sleeves the bulb body; the pressing block can be rotated relative to the bulb body without separating; a sleeve is inserted in the screw rod; a piston is mounted in the sleeve; the screw rod can move to the right side by a pushing piston; a rotating rod is inserted in the left end of the screw rod; the right end of the rotating rod is in contact with the sleeve; a flat key is arranged on the outer edge of the rotating rod; a key slot is formed in the inner side wall of the screw rod; through cooperation between the flat key and the key slot, the rotating rod is rotated to drive the screw rod to move left and right; a wedged groove, positioned on the left side of the key slot, is formed in the innerwall of the screw rod; and when the flat key is positioned in the wedged groove, the rotating rod only can drive the screw rod to rotate in one direction to enable the screw rod to move to the left side. The fixture is novel in concept.

Description

technical field [0001] The invention relates to the technical field of fixtures for aluminum product processing, in particular to a self-adaptive adjustable fixture for aluminum product processing. Background technique [0002] Aluminum profiles are gradually widely used in the industry. When processing profiles, due to their use occasions and design requirements, the size of the profiles has a large difference, and the profiles need to be clamped during processing to keep them in place. stabilized and then processed. [0003] Among the existing equipment, it is more commonly used to set vises on the workbench, or use cylinder clamps to clamp, and then process the workpiece. When using vises, it takes more time to clamp, but using cylinders When fixing, continuous air supply is required to maintain the stability of the cylinder, which will cause waste of resources, and the use of the cylinder in the workshop will cause a lot of noise, so it is necessary to design a fixture ...

Problems solved by technology

[0003] Among the existing equipment, it is more commonly used to set vises on the workbench, or use cylinder clamps to clamp, and then process the workpiece. When using vises, it takes more time to clamp, but using cylinders When fixing, continuous air supply is required to maintain the stability of the cylinder, which will cause waste of resources, and the use of the cylinder in the workshop will cause a lot of noise, so it is necessary to design a fixture that can quickly and stably fix aluminum profiles

[0004] In addition, because the material of the aluminum profile is relatively soft, and the pressing operation is very inconvenient in the processing of some special-shaped parts, when positioning the workpiece, the contact area between the force application surface and the surface of the workpiece should be increased, and the pressure should be applied vertically on the surface of the workpiece It can effectively guarantee the pressing effect of aluminum products. In addition, when the pressing force is large, it will cause certain damage to the surface of aluminum products. Therefore, an aluminum product that is easy to adjust and can adapt to various workpieces is designed. It is very necessary to use a fixture and a device that can effectively control the size of the clamping force
