Problems solved by technology
[0006] 1. With this tool, the installation work after the positioning of the metal pipe assembly needs to maintain the balance of the tool, which is inconvenient for the operator to work exclusively, and there is a risk of installation failure;
[0007] 2. Using this tool, if the connection method of the oil pipe is threaded connection, under the tightening torque, the metal pipe assembly may rotate in the positioning arc, causing the oil pipe to fail in positioning and eventually lead to installation failure

Embodiment Construction
[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0025] to combine Figure 1 to Figure 3 As shown, a hydraulic cylinder metal pipe assembly special tooling, two support bases 9 and two fixed side plates 10 are arranged on the support base plate 8 in the axial direction. The upper end of the support base 9 is provided with an arc-shaped groove or a V-shaped groove, and two fixed side plates 10 are relatively arranged on the right side of the support base plate 8 . During operation, the cylinder 6 is supported in ...

The invention discloses a special tooling for assembling a hydraulic cylinder metal pipe assembly, which belongs to the technical field of hydraulic cylinder assembly. Two support bases and two fixed side plates are arranged axially on the support base; the cylinder is supported on the two support bases, and the bottom end of the cylinder is fitted between the two fixed side plates; There are two guide rails radially arranged; a slider is slidably installed on the guide rail; a fixing groove is opened on the slider; the transition joint at one end of the metal pipe assembly fits into the fixing groove on the corresponding slider . In the present invention, the bottom surface of the fixed groove on the slider cooperates with the end surface of the joint body, so that the axis of the transition joint and the right-angle joint seat on the cylinder are well aligned, and the installation reliability of the metal pipe assembly is improved; the fixed groove on the slider has two The side can fix the joint body to ensure the installation position of the metal pipe assembly and facilitate installation.
Description
technical field [0001] The invention relates to the technical field of hydraulic cylinder assembly, in particular to a special tool for assembling a hydraulic cylinder metal pipe assembly. Background technique [0002] The hydraulic cylinder is an indispensable part of the hydraulic transmission system. In terms of the design of the oil circuit connected to the hydraulic cylinder, compared with the welded one-piece structure, the detachable pipeline connection is more and more popular in mechanical engineering due to its convenient maintainability. Favored by the industry market. [0003] First of all, as far as the metal pipe assembly connection technology is concerned, regardless of the ferrule connection or the threaded connection, due to the increase in the number of parts, the oil leakage failure point is larger than that of the welded type (it is different from the installation of the metal pipe assembly. The method has a great correlation); Secondly, the assembly err...
