Description

Technical Field

[0001] This utility model relates to the field of automotive testing fixtures, specifically to an indirect testing fixture. Background Technology

[0002] Automotive inspection tools are specialized measuring tools, and also non-standard measuring instruments customized for specific inspection needs. They are developed according to the specific planning and design requirements of each car model and can be used to measure and evaluate the dimensional quality of automotive parts.

[0003] The existing inspection tools still have the following problems when in use: many of the existing inspection tools have complex inspection structures, some products have simulated blocks or other inspection structures around them, or the surface to be inspected is restricted by the product's own structure, making it impossible to see visually or to directly use measuring tools such as feeler gauges to measure, which makes the inspection work difficult to carry out.

[0004] Therefore, it is necessary to invent an indirect detection tool to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an indirect inspection fixture to solve the problems mentioned in the background art, such as the complex inspection structure on existing fixtures, the presence of simulation blocks or other inspection structures around some products, or the restriction of the inspected surface by the product's own structure, making it impossible to visually inspect or directly measure with feeler gauges or other measuring tools, thus making the inspection work difficult to carry out.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an indirect inspection fixture, including a support, a sliding groove inside the support, a detection block slidably installed inside the sliding groove, and a push-pull handle threadedly connected to the tail end of the detection block. The detection block has a cavity inside, and a tightening component is slidably installed inside the cavity. The tightening component is threadedly connected to a pre-reserved threaded groove inside the support. The tightening component has a built-in anti-dislodgement component. Thus, after the detection block moves and comes into contact with the product being tested, the relative position of the detection block and the support is fixed by the tightening component. At this point, the relative position between the zero-position scale line and the tolerance range scale line can be visually observed to determine the difference between the surface of the product being tested and its theoretical position.

[0007] Preferably, the top wall of the support is provided with tolerance range scale lines, and the top wall of the detection block is provided with zero position scale lines. In the initial state, the zero position scale lines are aligned with the zero graduation lines on the tolerance range scale lines. In this way, after the detection end of the detection block contacts the product being tested, and the relative position of the detection block and the support is fixed, the relative position between the zero position scale lines and the tolerance range scale lines can be visually observed to determine how much the surface of the product being tested differs from the theoretical position.

[0008] Preferably, the inner wall of the groove is attached to the outer wall of the detection block to achieve a sliding connection. This ensures the accuracy of the direction and position of the detection block during the sliding process, and facilitates the subsequent sliding of the detection block and its contact with the object to be tested to complete the testing operation. At this time, the relative position between the zero-position scale line and the tolerance range scale line can be visually observed to determine how much the surface of the tested product differs from the theoretical position, which facilitates the subsequent reading of the test results. The overall testing process is relatively convenient.

[0009] Preferably, the tightening assembly includes a threaded rod that is threaded to the threaded groove, and the threaded rod is slidably connected to the cavity. A handle is fixedly installed at the top of the threaded rod. After the handle is turned to drive the threaded rod to rotate and fully match the threaded groove, the handle is tightly abutted against the top wall of the detection block, thus ensuring that the relative position of the detection block and the support is fixed.

[0010] Preferably, the anti-detachment component includes an annular groove pre-set inside the threaded rod, and an annular block is rotatably installed inside the annular groove. The limiting block fixedly connected to the outer wall of the annular block is slidably connected to the vertical groove. In this way, when the threaded rod rotates and moves up and down, the annular block moves up and down synchronously. The limiting block fixedly installed on the outer wall of the annular block slides inside the vertical groove. Thus, without affecting the rotation of the threaded rod, the range of motion of the threaded rod is the height of the vertical groove.

[0011] Preferably, the limiting blocks are provided in two quantities, and the two limiting blocks are arranged symmetrically with reference to the central axis of the annular block as the axis of symmetry.

[0012] Preferably, the inner wall of the vertical groove is attached to the inner wall of the limiting block to achieve a sliding connection, and the vertical groove is connected to the threaded groove. The top and bottom of the vertical groove are both closed. In this way, the range of motion of the threaded rod is the height of the vertical groove without affecting the rotation of the threaded rod, thus preventing the tightening component from falling off the support.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This invention ensures that the relative position of the test block and the support is fixed by moving the test block against the product being tested, turning the handle to drive the threaded rod to rotate and fully match the thread groove, and then the handle is tightly against the top wall of the test block. At this time, the relative position between the zero-position scale line and the tolerance range scale line can be visually observed to determine how much the surface of the product being tested is different from the theoretical position, thus completing the test. The monitoring process is convenient, quick, and relatively intuitive. Attached Figure Description

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model provides, for example Figure 1-4 The indirect inspection fixture shown includes a support 1, a groove 3 inside the support 1, a detection block 2 slidably installed inside the groove 3, and a push-pull handle 4 threadedly connected to the tail end of the detection block 2. A cavity 8 is provided inside the detection block 2, and a tightening component 5 is slidably installed inside the cavity 8. The tightening component 5 is threadedly connected to a threaded groove 6 reserved inside the support 1. The tightening component 5 has an anti-loosening component 7 built in.

[0019] After the detection block 2 moves and comes into contact with the product being tested, the relative position of the detection block 2 and the support 1 is fixed by tightening the component 5. At this time, the relative position between the zero-position scale line and the tolerance range scale line can be visually observed to determine how much the surface distance of the product being tested is from the theoretical position.

[0020] The top wall of support 1 is provided with tolerance range scale lines, and the top wall of detection block 2 is provided with zero position scale lines. In the initial state, the zero position scale lines are aligned with the zero graduation line on the tolerance range scale lines. After the detection end of the detection block 2 contacts the product being tested, and the relative position of the detection block 2 and support 1 is fixed, the relative position between the zero position scale lines and the tolerance range scale lines can be visually observed to determine how much the surface of the product being tested differs from the theoretical position.

[0021] The inner wall of the slide groove 3 is attached to the outer wall of the detection block 2 to achieve a sliding connection, thus ensuring the accuracy of the direction and position of the detection block 2 during the sliding process.

[0022] The tightening assembly 5 includes a threaded rod 502 that is threadedly connected to the threaded groove 6, and the threaded rod 502 is slidably connected to the cavity 8, and a handle 501 is fixedly installed at the top of the threaded rod 502.

[0023] This allows the handle 501 to be rotated, causing the threaded rod 502 to rotate and fully match the threaded groove 6. At this time, the lower end of the handle 501 is in close contact with the top wall of the detection block 2, which ensures that the relative position of the detection block 2 and the support 1 is fixed. This ensures that the front end of the detection block 2 is in contact with the object to be tested, and that the detection block 2 will not be displaced. At this time, the relative position between the zero-position scale line and the tolerance range scale line can be visually observed to determine how much the surface of the tested product differs from the theoretical position, thus facilitating the reading of the test results.

[0024] The anti-detachment component 7 includes an annular groove 701 pre-installed inside the threaded rod 502, and an annular block 702 is rotatably installed inside the annular groove 701. The limiting block 703 fixedly connected to the outer wall of the annular block 702 is slidably connected to the vertical groove 704. There are two limiting blocks 703, and the two limiting blocks 703 are symmetrically arranged with reference to the central axis of the annular block 702. The inner wall of the vertical groove 704 is attached to the inner wall of the limiting block 703 to achieve a sliding connection. The vertical groove 704 is connected to the threaded groove 6, and the top and bottom ends of the vertical groove 704 are closed.

[0025] The annular block 702 is rotatably connected to the threaded rod 502, and the limiting block 703 fixedly connected to the side wall of the annular block 702 is slidably connected to the vertical groove 704. In this way, when the threaded rod 502 rotates and moves up and down, the annular block 702 moves up and down synchronously. The limiting block 703 fixedly installed on the outer wall of the annular block 702 slides inside the vertical groove 704. In this way, without affecting the rotation of the threaded rod 502, the range of motion of the threaded rod 502 is the height of the vertical groove 704, thus preventing the tightening assembly 5 from falling off the support 1.

[0026] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
