Description

Technical Field

[0001] This utility model belongs to the technical field of brake drum position measurement fixtures, specifically relating to a brake drum position measurement fixture structure that is easy to operate. Background Technology

[0002] In automotive braking systems, the brake drum is a critical component, and its positional accuracy directly affects braking performance and driving safety. Therefore, detecting the positional accuracy of the brake drum is crucial. However, existing brake drum positional gauges have several problems in practical applications, mainly in the following aspects:

[0003] Currently, brake drum position gauges on the market often have complex structural designs. During the inspection process, operators need to use multiple tools and go through several tedious steps to complete the installation, positioning, and inspection of the gauge. For example, some gauges require manual adjustment of multiple bolts or clamps to fix the gauge and brake drum, which not only takes a long time to operate but is also prone to operational errors, resulting in low inspection efficiency and failing to meet the inspection needs of mass production.

[0004] Secondly, existing inspection fixtures lack effective limiting and stable support for the inspection components in their structural design. During the inspection process, the various components of the fixture are prone to displacement or shaking due to factors such as vibration and external forces, which affects the accuracy of the inspection results.

[0005] In addition, the existing inspection fixtures have poor overall stability. During multiple inspection operations, the various parts of the fixtures are prone to loosening or deformation, resulting in inconsistent results and poor repeatability.

[0006] To address this, we provide a convenient brake drum position gauge structure. Utility Model Content

[0007] The purpose of this invention is to provide a convenient brake drum position gauge structure that can solve the problems mentioned in the background art.

[0008] The specific technical solution adopted in this utility model is as follows:

[0009] A convenient brake drum position gauge structure includes a brake drum body, a gauge ring installed at the upper end of the brake drum body, a position gauge insertion hole opened on the upper surface of the brake drum body, an insertion hole opened on the surface of the gauge ring, and a gauge head inserted into the inner wall of the insertion hole for detecting the position of the brake drum body.

[0010] A limit assembly is connected between the inspection ring and the inspection head;

[0011] The limiting component includes a U-shaped block installed on the upper surface of the gauge ring and a limiting insertion hole opened on the periphery of the gauge head. Rectangular through slots are opened on both sides of the U-shaped block. A movable sleeve block is slidably connected to the inner wall of the rectangular through slot. An arc plate is fixedly connected between the two movable sleeve blocks. A limiting insertion rod is fixedly connected to the inner wall of the arc plate. A reset structure is connected between the rectangular through slot and the movable sleeve block.

[0012] A second limiting component is connected between the inspection ring and the U-shaped block;

[0013] A cross plate is fixedly welded to the inner wall of the inspection ring, and a vertical limiting component is connected to the upper surface of the cross plate to limit the upward movement of the U-shaped block.

[0014] The present invention is further configured such that: the vertical limiting component includes a mounting column fixedly welded to the center of the upper surface of the cross plate one, the upper end of the mounting column is fitted with a cross plate two, and the end of the cross plate two is fixedly connected with an annular limiting plate for pressing and securing the U-shaped block.

[0015] The present invention is further configured such that the limiting component two includes an insertion hole opened on the upper surface of the gauge ring and an insertion post fixedly connected to the lower surface of the U-shaped block, and the insertion post is inserted into the inner wall of the insertion hole.

[0016] The present invention is further configured such that: the reset structure includes a fixed rod fixedly connected between the two end walls of the rectangular through groove, a spring is sleeved around the fixed rod, and the movable sleeve block is slidably sleeved around the fixed rod.

[0017] The present invention is further configured such that: the vertical limiting component also includes a threaded hole opened at the upper end of the mounting column and a torque screw threadedly connected to the center of the cross plate, and the lower end of the torque screw is threadedly connected to the inner wall of the threaded hole.

[0018] The present invention is further configured such that: a pulling rod is inserted at the top of the U-shaped block, and one end of the pulling rod is fixedly connected to the outer wall of the arc-shaped plate; and a lifting handle is fixedly connected to the upper surface of the cross plate II.

[0019] The present invention is further configured such that: one end of the spring is fixedly connected to the end wall of the rectangular through groove, and the other end of the spring is fixedly connected to one end surface of the movable sleeve block.

[0020] The technical effects achieved by this utility model are as follows:

[0021] This utility model presents a user-friendly brake drum position gauge structure. Through the cooperation of a limiting component and a reset structure, the limiting and releasing operations of the gauge head are extremely simple. The operator only needs to move the arc plate by pulling the lever to insert or release the limiting rod into the limiting hole, thus achieving the limiting and releasing of the gauge head. No complicated tools or cumbersome operating procedures are required. At the same time, the reset structure ensures that the moving block can automatically reset after the external force is released. In addition, the design of the vertical limiting component and the second limiting component ensures the relative position stability between the components of the gauge structure, reducing the adjustment time during the inspection process. This convenient and efficient operation method can improve inspection efficiency, reduce labor intensity, and is suitable for the position inspection of large batches of brake drums.

During design and installation, emphasis is placed on the precision and stability of each component, ensuring high accuracy and stability in brake drum position measurement. Position gauge holes and inserts on the gauge ring and brake drum body, along with limiting components one and two, effectively limit the movement range of components such as the gauge head and U-block, avoiding measurement errors caused by component shaking or displacement during testing. The cooperation of the mounting post, cross plate two, annular limiting plate, and tightening screws further enhances the overall stability of the gauge structure, ensuring that the positions of each component remain unchanged during testing. This allows for more accurate measurement of the brake drum position and guarantees product quality. Attached Figure Description

[0028] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0029] like Figure 1-4 As shown, a convenient brake drum position gauge structure includes a first limiting component: a U-shaped block 6 is installed on the upper surface of the gauge ring 2, a limiting insertion hole 7 is opened around the gauge head 5, and rectangular through slots 8 are opened on both sides of the U-shaped block 6. A movable sleeve block 11 is slidably connected to the inner wall of the rectangular through slot 8. Then, an arc plate 12 is fixedly connected between the two movable sleeve blocks 11, and a limiting rod 13 is fixedly connected to the inner wall of the arc plate 12 so that the limiting rod 13 can be inserted into the limiting insertion hole 7. At the same time, a reset structure is connected between the rectangular through slot 8 and the movable sleeve block 11. Through the above operations, the installation of the brake drum body 1, gauge ring 2, gauge head 5, and first limiting component is completed. The gauge head 5 can move within the insertion hole 4, and the first limiting component can limit the gauge head 5, preparing for subsequent inspection of the position of the brake drum body 1.

[0030] like Figure 1-4 As shown, a cross plate 17 is fixedly welded to the inner wall of the inspection ring 2, and a mounting post 18 is fixedly welded to the center of the upper surface of the cross plate 17. A cross plate 29 is installed on the upper end of the mounting post 18 to ensure stable installation. An annular limiting plate 20 is fixedly connected to the end of the cross plate 29 so that the annular limiting plate 20 can press the U-shaped block 6.

[0031] like Figure 3-4 As shown, a insertion hole 15 is opened on the upper surface of the inspection ring 2 to ensure the size and positional accuracy of the insertion hole 15. An insertion post 16 is fixedly connected to the lower surface of the U-shaped block 6 so that the size of the insertion post 16 matches the insertion hole 15. The insertion post 16 is inserted into the inner wall of the insertion hole 15 to ensure a firm connection. After the installation of the second limiting component is completed, the relative position between the U-shaped block 6 and the inspection ring 2 is further restricted by the cooperation between the insertion post 16 and the insertion hole 15, thereby enhancing the overall stability of the inspection structure.

[0032] like Figure 4As shown, a fixing rod 9 is fixedly connected between the two end walls of the rectangular through groove 8. A spring 10 is sleeved around the fixing rod 9 to ensure that the spring 10 can extend and retract freely. The movable sleeve 11 is slidably sleeved around the fixing rod 9, so that the movable sleeve 11 can slide freely on the fixing rod 9. After the reset structure is installed, when an external force causes the movable sleeve 11 to move, the spring 10 is compressed or stretched. When the external force disappears, the spring 10 returns to its original state, driving the movable sleeve 11 to reset, so that the limiting insertion rod 13 can automatically insert into or disengage from the limiting insertion hole 7, realizing the limiting and releasing functions of the inspection head 5.

[0033] like Figure 3 As shown, a threaded hole 21 is opened at the upper end of the mounting post 18, and a torque screw 22 is threadedly connected to the center of the cross plate 2 19, so that the size of the torque screw 22 matches the threaded hole 21. The lower end of the torque screw 22 is threaded to the inner wall of the threaded hole 21, and the torque screw 22 is tightened by rotating it. The vertical limiting component is further reinforced. The cooperation between the torque screw 22 and the threaded hole 21 makes the connection between the cross plate 2 19 and the mounting post 18 more secure, enhances the vertical limiting effect, and ensures that the cross plate 2 19 and the annular limiting plate 20 press the U-shaped block 6 stably during the testing process.

[0034] like Figure 3-4 As shown, a lever 14 is inserted at the top of the U-shaped block 6, and one end of the lever 14 is fixedly connected to the outer wall of the arc-shaped plate 12, so that the lever 14 can drive the arc-shaped plate 12 to move. A lifting handle 23 is fixedly connected to the upper surface of the cross plate 2 19, ensuring that the lifting handle 23 is firmly installed. The arc plate 12 can be easily moved by the lever 14, thereby driving the limiting rod 13 to insert or disengage from the limiting insertion hole 7, realizing the limiting and releasing of the gauge head 5. The lifting handle 23 makes it convenient for the operator to lift the cross plate 2 19, thereby adjusting the position of the entire vertical limiting component, improving the convenience of operation.

[0035] like Figure 4 As shown, one end of the spring 10 is fixedly connected to the end wall of the rectangular through slot 8, which can be done by welding or other reliable connection methods. The other end of the spring 10 is fixedly connected to one end surface of the movable sleeve block 11, also using a reliable connection method. After both ends of the spring 10 are fixed, it can stably perform the reset function. When the movable sleeve block 11 is moved by an external force, the spring 10 is compressed or stretched. After the external force disappears, the spring 10 returns to its original state, driving the movable sleeve block 11 to reset, ensuring the normal operation of the limit component one, and enabling the inspection head 5 to accurately perform limit and inspection operations.

[0036] The working principle of this utility model is as follows: the inspection ring 2 is installed on the upper end of the brake drum body 1 so that the inspection ring 2 fits tightly with the brake drum body 1. At this time, the position insertion hole 3 opened on the upper surface of the brake drum body 1 corresponds to the insertion hole 4 opened on the surface of the inspection ring 2, which prepares for the subsequent inspection operation of the inspection head 5.

[0037] The cross plate 17 fixedly welded to the inner wall of the inspection ring 2 and its upper vertical limiting components, including the mounting post 18, the cross plate 29, and the annular limiting plate 20, cooperate with the U-shaped block 6. The initial positioning is achieved through the insertion hole 15 and the insertion post 16 of the limiting component 2, which limits the relative position between the U-shaped block 6 and the inspection ring 2 and ensures the stability of the inspection structure.

[0038] When it is necessary to limit the movement of the inspection head 5, the operator applies external force by pulling the lever 14. The lever 14 drives the arc plate 12 to move. The arc plate 12 drives the two moving sleeve blocks 11 to slide along the fixed rod 9 in the rectangular through groove 8. At the same time, the spring 10 is compressed. As the arc plate 12 moves, the limiting insert 13 fixedly connected to the inner wall of the arc plate 12 is inserted into the limiting insert hole 7 on the periphery of the inspection head 5, thereby limiting the movement of the inspection head 5 and keeping it in a specific inspection position.

[0039] When it is necessary to release the limit on the inspection head 5, the operator releases the pull rod 14, the compressed spring 10 returns to its original state, and the elastic force pushes the moving sleeve 11 to slide in the opposite direction, thereby driving the arc plate 12 and the limit rod 13 to move, so that the limit rod 13 disengages from the limit hole 7, and the inspection head 5 returns to a free movement state so as to carry out the next inspection operation.

[0040] The vertical limiting component, through the cooperation of the mounting column 18, the cross plate 29 and the annular limiting plate 20, vertically limits the U-shaped block 6. The annular limiting plate 20 is pressed and fixed on the U-shaped block 6 to prevent the U-shaped block 6 from moving upward during the inspection process, and to ensure the stability of the position of the limiting component and the inspection head 5.

[0041] Meanwhile, the threaded hole 21 at the upper end of the mounting post 18 and the torque screw 22 at the center of the cross plate 2 19 further reinforce the connection of the vertical limiting component. By rotating the torque screw 22, its lower end is threaded to the inner wall of the threaded hole 21, which enhances the connection strength between the cross plate 2 19 and the mounting post 18 and ensures the reliability of the vertical limiting.

[0042] After completing the installation and limiting operation of the gauge, insert the gauge head 5 into the insertion hole 4 so that it can move freely. By moving the gauge head 5, make it cooperate with the position insertion hole 3 on the upper surface of the brake drum body 1 for testing.

[0043] During the testing process, the limiting component 1 and the vertical limiting component ensure the stable position of components such as the gauge head 5 and the gauge ring 2, avoiding testing errors caused by component shaking or displacement. Operators can flexibly control the limiting and resetting of the gauge head 5 by using the lever 14 and the reset structure as needed to achieve multiple accurate testing operations.

[0044] The lifting handle 23 fixedly connected to the upper surface of the cross plate 2 19 makes it convenient for operators to lift the cross plate 2 19 and adjust the position of the vertical limiting component, which facilitates the installation and disassembly of the inspection tool.

[0045] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
