Assembly device and method of steel wire screw sleeve

Abstract

The invention relates to an assembly device and method of a steel wire screw sleeve. According to the assembly device and method, a series of problems existing in the manual installation of the steelwire screw sleeve, such as the low qualified rate, low efficiency and easy happening of tooth skipping are solved. The assembly device comprises a chuck, sliding screw rods and a screw rod core; the chuck is connected with a tightening device through a quick change interface which can rotate forward and backward in the axial direction of the quick change interface; the three sliding screw rods areuniformly distributed on the chuck, and can move radially and synchronously along the chuck to tightly support and fix the steel wire screw sleeve; centers of the chuck and the sliding screw rods penetrate through the screw rod core, and the screw rod core can move in a straight line in the axial direction of the chuck to the tail end to fix an installation handle of the steel wire screw sleeve and support the sliding screw rods; and the above three parts work in cooperation to achieve the installation of the steel wire screw sleeve. According to the assembly device, by changing the sizes ofthe sliding screw rods and the screw rod core, the installation of the steel wire screw sleeves with various sizes is achieved very conveniently, and the diversified requirements can be met.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to an assembly device and method of a wire screw sleeve. Background technique [0002] Wire thread insert is a new type of connection and fastening technology, which is commonly used in various low-strength materials, which can improve the wear resistance of screw connections and avoid damage to the connection threads. The wire thread sleeve is generally made of high-hardness corrosion-resistant steel wire with a diamond-shaped cross-section. It is a spring-shaped concentric body with internal and external threads. The outer thread is screwed into the thread groove specially installed on the machine part, and the inner thread is The standard internal thread used for the fastening of connectors has a cross-sectional shape that is a combination of two internal and external threads. [0003] At present, the installation of wire threaded sleeves is basically a...
