Description

Technical Field

[0001] The utility model belongs to the field of hydraulic brake hoses, and relates to a tooling for conveniently and quickly and accurately determining the positioning position of the intermediate joint of a hydraulic brake hose. Background Technique

[0002] As one of the important means of transportation for people, the safety performance of automobiles has been increasingly emphasized by people. The braking performance directly affects the safety of the entire vehicle, and the hydraulic brake hose, as one of the important components in the braking system, its performance is directly related to driving safety. During the driving process of a vehicle, the hydraulic brake hose mainly has two movement modes: one is that the up and down movement of the suspension driven by the bumpy vehicle drives the hose to vibrate up and down, and the other is that the left and right rotation of the vehicle drives the hose to rotate left and right.

[0003] The hydraulic brake hose assembly generally consists of 2-4 metal joints and a section of brake hose, as Figure 1 shown. When there are 3 or 4 metal joints on the brake hose assembly, usually 1-2 metal joints need to be sleeved on the brake hose and then fixed through riveting. Such metal joints fixed on the brake hose are collectively referred to as intermediate joints. When installing the brake hose assembly, the intermediate joints are usually installed on the suspension and move along with the suspension during vehicle driving. The accuracy of the positioning dimension L of the intermediate joints determines whether there will be interference during the movement of the hose, thus affecting the performance of the hydraulic brake hose. Therefore, the accuracy of the positioning dimension of the intermediate joints is crucial.

[0004] Currently, the positioning method for riveting the intermediate joints of hydraulic brake hoses: ① Check the positioning dimension L marked on the drawing; ② Sleeve the intermediate joint onto the brake hose, use a length scale to measure the positioning dimension, slide the intermediate joint to the positioning dimension, and make a marking line on the hose with a paint pen; ③ Pick up the brake hose and the intermediate joint, insert the hose into the sleeve of the riveting machine, push the intermediate joint to the marking line; ④ Move the contact switch until it touches the end face of the hose, and use bolts to fix the contact switch.

[0005] In the above operation process, there are the following disadvantages: ① The positioning dimension of the intermediate joint is measured with a length scale and a marking line is drawn on the hose with a paint pen, resulting in low work efficiency; ② Using a paint pen to make a marking line, the thickness of the marking line cannot be accurately controlled, resulting in poor accuracy of the positioning position; ③ After the hose is inserted into the sleeve, pushing the intermediate joint to the marking line, this process is visually confirmed, resulting in poor accuracy of the positioning position and poor consistency of the positioning dimensions of different batches of products. Summary of the Invention

[0006] The purpose of the utility model is to provide a positioning tooling for the intermediate joint of a hydraulic brake hose to solve the defects in the prior art.

[0007] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a hydraulic brake hose intermediate joint positioning tool, which includes a metal cylinder with a scale, a movable metal slider and a locking bolt. The movable metal slider is slidably mounted on the metal cylinder, and a threaded through hole is provided on one side of the metal slider. The locking bolt is threadedly installed in the threaded through hole. The metal slider is fixed on the metal cylinder by screwing in the locking bolt, and the metal slider and the metal cylinder are loosened by unscrewing the locking bolt to achieve sliding.

[0008] As a further preferred embodiment of this solution, a rectangular plane is cut on the metal cylinder.

[0009] As a further preferred embodiment of this solution, length scales are engraved on the rectangular plane.

[0010] As a further preferred embodiment of this solution, the measuring range of the length scale is 500 mm and the accuracy is 0.5 mm.

[0011] As a further preferred embodiment of this solution, the outer diameter of the metal cylinder is 10-11 mm, and the cutting depth of the rectangular plane is 1-3 mm.

[0012] As a further preferred embodiment of this solution, the metal slider is a large and small cylindrical structure, with a hole with a diameter of 10-11 mm in the center for use with the metal cylinder.

[0013] As a further preferred embodiment of this solution, the small cylindrical part of the metal slider contacts and cooperates with the riveting machine sleeve, the outer diameter of this part of the cylinder is 13-16 mm, and the length is 20-25 mm. The large cylindrical part of the metal slider is used for contact with the hand for operation, and the outer diameter of this part of the cylinder is 15-25 mm, and the length is 10-15 mm.

[0014] As a further preferred embodiment of this solution, the locking bolt is a hexagon socket bolt with a specification of M2.

[0015] The beneficial effects of the utility model are:

[0016] (1) The hydraulic brake hose intermediate joint positioning fixture has a length scale on its metal cylinder. After checking the positioning dimension L in the drawing, the metal slider can be quickly moved to the corresponding positioning dimension and fixed with a locking bolt. This eliminates the need for the existing process of using a length ruler for positioning, drawing lines with a paint pen, and inserting a sleeve and then manually pushing and visually confirming that the intermediate joint has reached the positioning position, thereby greatly improving work efficiency.

[0017] (2) For the positioning tooling of the intermediate joint of this hydraulic brake hose, the accuracy of the length on the metal cylinder is 0.5 mm. Therefore, the deviation of the metal slider moving to the positioning dimension is less than 0.5 mm, which not only ensures the accuracy of the positioning dimension but also improves the consistency of the positioning dimensions of products in different batches.
