Description

Technical Field

[0001] This utility model relates to the field of tapered part processing technology, and in particular to a vacuum adsorption fixture for processing irregular tapered parts. Background Technology

[0002] In the fields of machinery manufacturing, aerospace, and automotive parts, irregular tapered parts are increasingly used as key structural components. These parts typically have characteristics such as non-linear generatrices, irregular taper changes, and complex surface contours. Their machining accuracy directly affects the assembly performance and operational stability of the overall equipment. Currently, the tooling for machining tapered parts is divided into two types: mechanical clamping and adsorption. Among them, adsorption tooling is mainly used to adsorb flat, regular machined parts. However, in the aforementioned existing technologies, the adsorption surface of traditional vacuum adsorption fixtures is mostly a fixed plane, which cannot achieve complete contact with the complex surface of irregular conical parts, reducing the stability of the adsorption force. It may also cause processing deviations due to loosening of parts, or even cause parts to be scrapped.

[0003] Therefore, there is an urgent need to provide a vacuum adsorption fixture that can conform to irregular conical parts. Utility Model Content

[0004] The purpose of this invention is to provide a vacuum adsorption fixture for processing irregular conical parts, which aims to solve the problems in the prior art that it is impossible to achieve complete fit with the complex surface of irregular conical parts, which reduces the stability of the adsorption force and may cause processing deviations or even scrap the parts due to loosening of the parts.

[0005] To achieve the above objectives, this utility model provides a vacuum adsorption fixture for processing irregular conical parts, including an assembly base, a suction piston, a connecting base, a conical negative pressure head, and a suction pipe. The connecting base is detachably connected to the assembly base and is located on one side of the assembly base. The conical negative pressure head is detachably connected to the connecting base and is located on one side of the connecting base. The suction pipe is disposed on the inner wall of the conical negative pressure head and is detachably coupled to the assembly base. The suction piston is disposed on the inner wall of the assembly base.

[0006] The vacuum adsorption fixture for processing irregular conical parts further includes a sealing ring, and the conical negative pressure head has a mounting groove that is adapted to the sealing ring.

[0007] The vacuum adsorption fixture for machining irregular conical parts further includes a first countersunk hexagonal bolt, the conical negative pressure head has a first countersunk hole, the first countersunk hole is rotatably engaged with the first countersunk hexagonal bolt, and the connecting seat has a first threaded hole, the first threaded hole is threadedly engaged with the first countersunk hexagonal bolt.

[0008] The vacuum adsorption fixture for machining irregular conical parts further includes a second countersunk hexagonal bolt. The connecting seat has a second countersunk hole, which is rotatably engaged with the second countersunk hexagonal bolt. The mounting seat has a second threaded hole, which is threadedly engaged with the second countersunk hexagonal bolt.

[0009] This utility model discloses a vacuum adsorption fixture for machining irregular conical parts. In use, the mounting base is connected to the output end of the hydraulic cylinder. The conical workpiece is tightly screwed onto the conical negative pressure head through the thread. Then, the hydraulic cylinder is activated to pull the suction piston to perform negative pressure suction, causing the internal gas to move along the suction pipe, generating negative pressure and adsorbing the conical workpiece. In this way, the problem of not being able to achieve complete adhesion with the complex surface of irregular conical parts, reducing the stability of the adsorption force, and the possibility of machining deviations or even scrapping the parts due to loose parts is solved.
