Hydraulic oil cylinder outer pipe cylinder barrel clamping tool clamp

Abstract

The invention relates to the technical field of welding tool clamps, in particular to a hydraulic oil cylinder outer pipe cylinder barrel clamping tool clamp which comprises a workbench, a rotary clamp table assembled on the workbench and a pipe opening positioning clamp assembled on the workbench. The rotary clamp table comprises a rotary table mechanism assembled on the working table, the rotary table mechanism comprises a rotary platform which is vertically and rotatably installed, and a synchronous positioning clamp used for axially aligning a cylinder part of a cylinder barrel with a flange plate is arranged on the rotary platform. A pressing mechanism used for pressing the cylinder part of the cylinder barrel and the flange plate is arranged on the upper end face of the rotary platform. The tool clamp provided by the invention can be used as a hydraulic cylinder barrel welding positioning clamp, can replace manual work to realize rapid and automatic alignment of a welding part, and solves the problems of trouble of manual adjustment and uncontrollable error and unreliable precision in the manual adjustment process.

Description

technical field [0001] The invention relates to the technical field of welding fixtures, and specifically proposes a clamping fixture for an outer tube of a hydraulic oil cylinder. Background technique [0002] Hydraulic cylinders are also called hydraulic cylinders. Hydraulic cylinders are hydraulic actuators that convert hydraulic energy into mechanical energy and perform linear reciprocating or oscillating motions; hydraulic cylinders are composed of cylinder barrel and cylinder head, piston and piston rod, sealing device, buffer device and exhaust Gas device composition.

Problems solved by technology

[0003] The outer tube of the hydraulic cylinder, as the name implies, is a metal shell located on the outermost layer of the hydraulic cylinder with a tube structure. According to different structural designs, the structure of the outer tube of the hydraulic cylinder is different, such as Figure 11 Shown is a type of cylinder structure that has the features shown in the figure and differs only in diameter or length. The cylinder body consists of a cylinder part, a flange at one end of the cylinder part, and a The two nozzles on the side wall of the cylinder are composed of two nozzles, the flange is used for the fixed installation of the hydraulic cylinder, and the two nozzles are the inlet and outlet connections of the two hydraulic pipes in the hydraulic cylinder in the hydraulic system; When forming the cylinder of this type of structure, the flange plate and the two nozzles are independent structures, which need to be welded with the cylindrical part of the cylinder structure by welding. In the actual welding process , mostly completed by manual welding, but there are the following disadvantages in manual welding: 1. The hydraulic cylinder itself is a precision device that requires high assembly accuracy, so welding accuracy needs to be considered during welding processing, and for flanges and cylinders For the butt welding of the end of the cylindrical part, it is especially necessary to pay attention to the axial alignment of the flange and the cylindrical part of the cylinder. During manual welding, it is usually adjusted by manual placement, but the accuracy of manual adjustment is not reliable. The error is uncontrollable, and the flange and the cylindrical part of the cylinder are usually not aligned and pressed during welding, so it is easy to cause deviation during the welding process, and at the same time, the welding heat deformation of the material at the welding interface cannot be suppressed

[0004] 2. For the welding of the nozzles, since the two nozzles are welded on the arc side wall of the cylinder, the welding positioning of the nozzles is troublesome, and it is necessary to manually adjust and align the welding positions one by one.
