Buffer double-head cap screwing device

Abstract

The invention provides a buffering type double-end cap screwing device which comprises an outer cap jacking-in device, a clamping fixture used for containing a wire suite and a cap screwing device body. The cap screwing device body comprises a fixation board which is connected with a horizontal moving air cylinder through a direct-current brushless motor. A vertical moving air cylinder is arranged on one side of the horizontal moving air cylinder, and a connection rod is arranged on the fixation board. Two spacer bushes and a bearing sleeve are arranged outside the connection rod, and bearings are arranged between the two spacer bushes and the bearing sleeve. A pressure rod is arranged on the lower portion of the connection rod, and a connection sleeve is arranged outside the pressure rod. The connection sleeve is fixedly connected with the bearing sleeve through a screw, and a spring is arranged on the pressure rod. A reversed-U-shaped groove is formed in the lower portion of the pressure rod, and a rubber pad is arranged in the groove. The two sides of the groove are provided with steel balls respectively, and small springs are arranged at the rear ends of the steel balls. The outer cap jacking-in device comprises an air cylinder, and an ejector rod is arranged on the upper portion of the air cylinder. According to the buffering type double-end cap screwing device, automatic assembling of a bottle cap of the wire suite is achieved, the problem that the working efficiency of manual assembling is low is solved, meanwhile, the phenomenon that a workpiece is screwed broken due to rigid and tight extrusion is avoided, and working efficiency and assembling precision are improved.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a buffer type double-head cap screwing device. Background technique [0002] Due to a wire kit bottle cap with a semicircular step encountered during the production process (see Figure 4 ), when assembling, the manpower must grasp the outer cover and slowly enter the wire kit, the efficiency of manual assembly is low, and the assembly accuracy is low; if the outer cover is directly put into the wire kit with the help of tooling, the inner and outer screws are prone to skew due to the influence of the steps , resulting in failure to assemble. Contents of the invention [0003] The invention provides a buffer type double-head cap screwing device, which solves the disadvantages of low assembly efficiency and easy skewing of inner and outer threads in the background technology. [0004] The technical solution of the present invention is achieved in the following way: the buff...
