Cylinder body and cylinder head pairing method of a kind of miniature cylinder

Abstract

The invention relates to the technical field of air cylinder equipment, and in particular relates to a cylinder body and a cylinder cover pairing method of a mini-air cylinder. The pairing method comprises the following steps: (1) taking an internal thread jig I, and dividing one end of the circle into N equant and marking; (2) taking a plane jig II, drawing a circle on the plane jig II, dividing the circle into N equant and marking, and enabling the mark to be in one-to-one correspondence with the mark on the jig I; (3) twisting a front cylinder cover to one end which is marked, of the jig I, according to the mark corresponding to the port of the front cylinder cover, taking down the front cylinder cover and putting part on the jig II corresponding to the mark part, then classifying all front cylinder cover; (4)taking a pairing cylinder body to be paired, twisting any classified front cylinder cover of the jig II on the cylinder body, and then twisting the rear back cylinder cover to the other end of the cylinder body; (5) and vertically positioning the cylinder body on the centre of the jig II, aligning the front cylinder cover to classified mark, writing down the mark corresponding to the centre of the port of the rear back cylinder cover, taking one front cylinder cover from the marked part to replace the original front cylinder cover, and completing the pairing. The pairing method provided by the invention has the advantage of greatly improving the production efficiency.

Description

technical field [0001] The invention relates to the technical field of cylinder equipment, in particular to a matching method for a cylinder body and a cylinder head of a miniature cylinder. Background technique [0002] As we all know, the application range of mini cylinder is more and more extensive, so the output of its production is also expanding day by day. The mini cylinder is composed of a cylindrical cylinder body and a front cylinder head and a rear cylinder head which are threaded at both ends of the cylinder body, and one side of the front cylinder head and the rear cylinder head is provided with an interface. The interface with the rear cylinder head must be in the same direction. The current production process of the front cylinder head and the rear cylinder head is to turn the thread first, and then make the interface. Therefore, for the interface, the entry point of the thread in the circumferential direction is random, and the threads at both ends of the cy...

Problems solved by technology

The existing method is to screw the front cylinder head or the rear cylinder head first, and then choose a different rear cylinder head or front cylinder head to match with it. It often takes several trial selections to successfully match, and the production efficiency is extremely low.
