Description

Technical Field

[0001] This utility model belongs to the technical field of shape inspection tooling, and more specifically, it relates to a shape inspection tooling for automotive brake hard pipes. Background Technology

[0002] Automotive brake hoses are critical components in the braking system, transmitting high-pressure brake fluid and needing to withstand pressures exceeding 10-20 MPa. Their core characteristics include high pressure resistance, corrosion resistance, vibration resistance, and excellent sealing to ensure accurate transmission of braking commands. Structurally, they must meet stringent requirements for bending radius and wall thickness and undergo multiple verifications, including pulse testing and burst testing. As a safety component, their quality directly affects braking response speed and reliability, forming a fundamental guarantee of driving safety.

[0003] Based on the above, the inventors have discovered the following problem: In the production process of automotive brake hard pipes, the inspection of their shape is a crucial step to ensure that the product's quality and safety performance meet the standard requirements. Currently, this inspection process typically involves a series of testing methods. While these methods can effectively identify defective products, they are often complex to operate and require significant time and manpower.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a tooling for inspecting the shape of automotive brake hard pipes, in order to achieve a more practical purpose. Utility Model Content

[0025] As attached Figure 1 To be continued Figure 3 As shown:

[0026] This utility model provides a tooling for inspecting the shape of automotive brake hard pipes, including a mounting platform 1, which is preferably square and made of metal. A lower mold 2 is mounted on the surface of the mounting platform 1, and a mounting bracket 3 is mounted on the surface of the mounting platform 1. An upper mold 5 is mounted on the mounting bracket 3 via a driving mechanism 4. The driving mechanism 4 is used to move the position of the upper mold 5 so that the lower mold 2 and the upper mold 5 are combined. The upper mold 5 is located directly above the lower mold 2. The lower mold 2 and the upper mold 5 are the same size. The surfaces of the lower mold 2 and the upper mold 5 are provided with contour grooves 6. The shape of the contour grooves 6 is designed according to the shape of the brake hard pipe. A pressure sensor 7 is installed in the contour groove 6 of the upper mold 5.

[0027] In this design, a slot 8 is formed on one side of the contour groove 6 on the upper mold 5. One end of the slot 8 is connected to the contour groove 6, and the other end extends to the side surface of the upper mold 5. The pressure sensor 7 is located in the contour groove 6 and the slot 8. A controller 9 is installed at one end of the pressure sensor 7 on the side surface of the upper mold 5. The controller 9 is used to receive and transmit the signal from the pressure sensor 7. The controller 9 is installed on the side surface of the upper mold 5. The pressure sensor 7 and the controller 9 are both existing technologies and will not be described in detail here. The pressure sensor 7 is a strip pressure sensor and is attached to the contour groove 6 of the upper mold 5.

[0028] When in use, the brake hard tube that needs to be visually inspected can be placed in the contour groove 6 of the lower mold 2, and then the drive mechanism 4 is started to move the upper mold 5. When the lower mold 2 and the upper mold 5 are combined, the pressure sensor 7 will detect the pressure. The controller 9 receives the electrical signal and transmits the data to a mobile phone or other receiving device. The normal pressure value of the brake hard tube is within a pressure range. When the pressure is greater than or less than this range, the brake hard tube is unqualified. Through the above design, the appearance of the brake hard tube can be quickly inspected, which improves work efficiency.

[0029] The mounting frame 3 includes a first connecting plate 301 connected to the mounting platform 1 and a second connecting plate 302 connected to the first connecting plate 301. The mounting frame 3 is L-shaped, and a drive mechanism 4 is mounted on the second connecting plate 302.

[0030] The driving mechanism 4 includes an electric cylinder 401 mounted on the second connecting plate 302. The electric cylinder 401 passes through the second connecting plate 302 and is mounted on an mounting plate 402, which is connected to the upper mold 5.

[0031] When in use, when the brake hard tube is placed in the contour groove 6 on the lower mold 2, the electric cylinder 401 can be activated. The activation of the electric cylinder 401 will drive the mounting plate 402 to move, thereby driving the upper mold 5 to move, so that the lower mold 2 and the upper mold 5 are merged.

[0032] The lower mold 2 and the mounting platform 1, as well as the mounting plate 402 and the upper mold 5, are connected by bolts 10. Through the connection of bolts 10, the lower mold 2 and the upper mold 5 of different contour grooves 6 can be quickly replaced, thereby enabling the testing of different brake hard tubes.

[0033] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
