Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of automobile leather cup detection, and specifically relates to an inner and outer diameter detection device for leather cup production. BACKGROUND

[0002] In an automobile brake system, a brake leather cup (usually referring to a brake cylinder leather cup or a brake caliper leather cup) is a key sealing component, and its quality directly relates to the stability of the automobile brake system.

[0003] The sealing function of the leather cup depends on the contact pressure of the inner and outer diameters with the cylinder body and the piston. The inner and outer diameter size deviation will cause uneven compression of the sealing lip (usually a lip structure), form local gaps, cause brake fluid leakage, and directly affect the pressure transmission efficiency of the brake system. For example, in a drum brake, if the fitting gap between the outer diameter of the leather cup and the inner diameter of the wheel cylinder exceeds the design value, the hydraulic pressure during braking will push the leather cup to expand outward, aggravate the lip wear, and even cause the "cylinder biting" phenomenon.

[0004] Therefore, it is particularly important to detect the inner and outer diameter sizes of the automobile brake leather cup. Currently, the inner and outer diameters of the automobile leather cup are generally measured by manually holding a vernier caliper. However, the measurement efficiency is slow, and the position of the vernier caliper needs to be changed frequently for different measurement points, which is very troublesome.

[0005] Therefore, the utility model provides an inner and outer diameter detection device for leather cup production to solve the above problems. UTILITY MODEL CONTENTS

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] This utility model relates to a device for detecting the inner and outer diameters of leather bowls during production, such as... Figures 1-2 As shown, the device includes a base 1, on which a first scale rod 2 is vertically mounted. A connector 3 is slidably mounted on the first scale rod 2. A second scale rod 4, perpendicular to the direction of the first scale rod 2, is connected to the periphery of the connector 3. Several inner and outer diameter measuring claws 5, used for measuring the inner and outer diameters and lip length of automotive brake cups, are slidably mounted on the periphery of the second scale rod 4. In order to facilitate the measurement of the inner and outer diameters of the brake cups, in this embodiment, four sets of inner and outer diameter measuring claws 5 are provided.

[0033] Specifically, the connector 3 has an axially formed first connecting hole 31 that matches the first scale rod 2. The first scale rod 2 is inserted into the first connecting hole 31 to achieve a sliding connection with the connector 3. By sliding the connector 3 on the first scale rod 2, the connector 3 can drive the second scale rod 4 to move up and down to adjust the height of the second scale rod 4, which is convenient for adaptive adjustment according to the height of the leather cup to be measured.

[0034] Furthermore, to facilitate the fixing of the connector 3 to the first scale rod 2, such as... Figure 4 As shown, a first positioning hole 32 communicating with the first connecting hole 31 is radially formed on the periphery of the connector 3. The inner wall of the first positioning hole 32 has a threaded structure, and a positioning bolt 6 is internally threaded onto it. When the connector 3 is slidably moved to the desired position, the positioning bolt 6 is tightened to make it tightly abut against the periphery of the first scale rod 2, thereby fixing the connector 3. At the same time, in order to make the positioning bolt 6 better abut against the first scale rod 2, the periphery of the first scale rod 2 near the positioning bolt 6 is made into a plane. When the positioning bolt 6 abuts against the first scale rod 2, surface contact is achieved through this plane.

[0035] Furthermore, such as Figure 3 As shown, a second connecting hole 51, adapted to the second scale rod 4, is provided on the inner and outer diameter measuring claw 5 along the extension direction of the second scale rod 4. The inner and outer diameter measuring claw 5 is slidably sleeved on the periphery of the second scale rod 4 through the second connecting hole 51. At the same time, a second positioning hole 52, communicating with the second connecting hole 51, is provided on the top of the inner and outer diameter measuring claw 5. The inner wall of the second positioning hole 52 has a threaded structure, and its internal thread connects to the positioning bolt 6. Similar to the positioning of the connecting piece 3, by tightening the positioning bolt 6, the end of the positioning bolt 6 abuts against the top surface of the second scale rod 4 to fix the inner and outer diameter measuring claw 5. The top of the second scale rod 4 can also be made flat to form a surface contact with the positioning bolt 6. It should be noted that the two sides of the inner and outer diameter measuring claw 5 should also be flat to better fit the inner and outer walls of the cup and to better read the dimensions.

[0036] In order to measure the overall height of the leather cup, the bottom surface of the second scale rod 4 is also designed to be flat. This flat surface is at the same level as the bottom surface of the connector 3. Furthermore, this flat surface can be adjusted to fit the top surface of the leather cup by adjusting the height of the second scale rod 4.

[0037] It should be noted that the scale values ​​on the surface of the second scale rod 4 gradually increase from the center to both ends, while the scale values ​​on the surface of the first scale rod 2 gradually increase from the bottom upwards.

[0038] Taking the specific measurement of a leather bowl as an example, such as Figure 5As shown, first, according to the standard cup size required by actual production, the position of the inner and outer diameter measuring claws 5 on the second scale rod 4 is adjusted, and is fixed by the positioning bolt 6, then the second scale rod 4 is lifted to move upward, the cup to be detected is placed on the center of the top surface of the base 1, the bottom surface of the second scale rod 4 is made to adhere to the top surface of the cup by sliding downward, at this time, the bottom of the inner and outer diameter measuring claws 5 extends into the inner and outer sides of the cup, the adhesion between the two sides of the inner and outer diameter measuring claws 5 and the inner and outer walls of the cup is observed to determine whether the cup meets the production standard, meanwhile, the height of the second scale rod 4 on the first scale rod 2 realizes the measurement of the overall height of the cup to determine whether it meets the production standard.

[0039] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing detailed description of the present application is made with reference to the foregoing embodiments, for those skilled in the art, it still can be modified to the technical solutions recorded in the foregoing embodiments, or equivalent replacement of some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
