A special testing tool for detecting symmetry of automobile parts

Abstract

This utility model discloses a special inspection tool for symmetry testing of automotive parts, including a support table. A working platform is installed on the upper end of the support table at the left side. The device has multiple insertion holes distributed at the rear end of the upright. The X-axis is installed on the upright through a sleeve frame. The sleeve frame is fitted onto the outer wall of the upright and can move up and down along the upright. When adjusting the height of the sleeve frame, the fixed handle is pulled outward, causing the insertion post to move out of the insertion hole. The movement of the insertion post causes the circular plate to compress the stainless steel spring. At this time, the sleeve frame can be controlled to move up and down along the upright. After adjusting to a suitable height, the handle is released to release the compression energy, and the insertion post is inserted into the corresponding insertion hole, thereby completing the height adjustment of the sleeve frame. This method increases the flexibility of the equipment.

Description

Technical Field

[0001] This utility model belongs to the technical field of special inspection tools for symmetry testing of automotive parts, specifically relating to a special inspection tool for symmetry testing of automotive parts. Background Technology

[0002] Specialized inspection fixtures for symmetry testing of automotive parts are precision measuring tools designed and manufactured specifically for the specific structure and symmetry testing standards of automotive parts. They typically consist of a base, a positioning device, and a measuring mechanism. The base provides a stable support platform, the positioning device precisely fixes the part being tested, ensuring its accurate position and preventing displacement during testing, and the measuring mechanism uses dial indicators, micrometers, or high-precision sensors to measure and collect data on the positional deviations of corresponding features on both sides of the part in real time. During testing, the part is mounted on the fixture according to regulations. By observing the readings of the measuring instruments or analyzing the data transmitted by the sensors, it is possible to quickly and accurately determine whether the symmetry of the part meets the design and process requirements. This provides a reliable basis for the processing quality control and assembly accuracy of automotive parts, ensuring the stability and reliability of the overall performance of the vehicle.

[0003] When using a special inspection tool for symmetry testing of automotive parts, the height of the measuring head cannot be flexibly adjusted according to the part being measured, which limits the flexibility of its use as the measuring head cannot inspect parts that are too large or too small. Utility Model Content

[0004] The purpose of this utility model is to provide a special inspection tool for inspecting the symmetry of automotive parts, in order to solve the problem that the height of the measuring head of the special inspection tool for inspecting the symmetry of automotive parts proposed in the background art cannot be flexibly adjusted according to the part being measured, so that the measuring head cannot inspect parts that are too large or too small, which limits its flexibility of use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a special inspection tool for symmetry testing of automotive parts, comprising a support table, a work platform installed on the upper left side of the support table, and a vertical rod installed on the upper right side of the support table. Multiple insertion holes are distributed at the rear end of the vertical rod. A connecting frame is sleeved on the outer wall of the vertical rod through the insertion holes. A groove is provided at the upper and lower rear end of the connecting frame. A fixed handle is installed at the rear end of the connecting frame. An insertion post is fixed at the upper and lower front end of the fixed handle. A circular plate is fixed on the outer wall of the insertion post, and a stainless steel spring is fixed at the rear end of the circular plate.

[0006] Preferably, an X-axis is fixed at a right angle at the front end of the socket frame, and grooves are provided at both ends of the X-axis.

[0007] Preferably, a reinforcing rib is fixed at the lower end of the X-axis, and the side end face of the reinforcing rib is fixed to the sleeve frame.

[0008] Preferably, the X-axis is fitted with a Y-axis via a groove at a position on the outer wall, and a measuring head is installed below the Y-axis.

[0009] Preferably, both the measuring head and the Y-axis are equipped with motors. The Y-axis moves back and forth along the X-axis under the drive of the motor, and the measuring head moves up and down under the drive of the motor.

[0010] Preferably, the upright is fixed at a perpendicular angle to the table surface at the upper end of the supporting table body.

[0011] Preferably, a plurality of ball bearings are fitted onto the inner wall of the sleeve frame, and the ball bearings are in close contact with the upright.

[0012] Preferably, the circular plate and the stainless steel spring are sleeved inside the groove, and the fixed handle is pulled outward to move the circular plate and the stainless steel spring inside the groove.

[0013] Compared with the prior art, this utility model provides a special inspection tool for symmetry testing of automotive parts, which has the following beneficial effects: This device has multiple insertion holes distributed at the rear end of the upright. The X-axis is installed on the upright via a socket frame, which fits onto the outer wall of the upright and can move up and down along the upright. To adjust the height of the socket frame, pull the fixing handle outward to move the insertion post out of the insertion hole. The movement of the insertion post causes the circular plate to compress the stainless steel spring. At this time, the socket frame can be controlled to move up and down along the upright. After adjusting to the appropriate height, release the handle to release the compression energy and insert the insertion post into the corresponding insertion hole, thus completing the height adjustment of the socket frame. This method increases the flexibility of the equipment.

[0014] Multiple ball bearings are fitted inside the socket frame. When the socket frame moves up and down along the upright, the ball bearings rotate at their positions against the outer wall of the upright, which increases the flexibility of the socket frame's movement.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The utility model provides, for example Figure 1-4The invention shown is a special inspection tool for symmetry testing of automotive parts, including a support table 1. A work platform 2 is installed on the upper left side of the support table 1, and a vertical rod 8 is installed on the upper right side of the support table 1. Multiple insertion holes 9 are distributed at the rear end of the vertical rod 8. A connecting frame 6 is sleeved on the outer wall of the vertical rod 8 through the insertion holes 9. A groove 11 is provided at the upper and lower rear end of the connecting frame 6. A fixing handle 7 is installed at the rear end of the connecting frame 6. An insertion post 14 is fixed at the upper and lower front end of the fixing handle 7. A circular plate 12 is fixed on the outer wall of the insertion post 14. A stainless steel spring 13 is fixed at the rear end of the circular plate 12.

[0023] The automotive parts are placed on a fixed platform. Utilizing the mobility of the Y-axis 5 and the measuring head 3, the measuring head 3 is brought close to or in contact with the part of the part whose symmetry needs to be tested. The measuring head 3 acquires the relevant positional data of the part and transmits the data to the testing system for analysis and processing via a data transmission line. By comparing the data with the standard symmetry data, the system determines whether the symmetry of the part is qualified.

[0024] like Figure 1 and Figure 2 As shown, an X-axis 4 is fixed at a right angle at the front end of the socket frame 6. Slide grooves are provided at both ends of the X-axis 4. A reinforcing rib 15 is fixed at the lower end of the X-axis 4. The side end face of the reinforcing rib 15 is fixed to the socket frame 6. The X-axis 4 is sleeved with a Y-axis 5 at the outer wall position through the slide groove. A measuring head 3 is installed below the Y-axis 5. Both the measuring head 3 and the Y-axis 5 are equipped with motors. The Y-axis 5 moves back and forth along the X-axis 4 under the drive of the motor, and the measuring head 3 moves up and down under the drive of the motor.

[0025] The measuring head 3 contacts the surface of the component. The measuring head 3 has a built-in high-precision displacement sensor. When the measuring head 3 contacts the surface of the component, minute geometric changes on the surface of the component, such as undulations or depressions that deviate from the ideal symmetrical position, will cause the measuring head 3 to move. The sensor converts this displacement change into an electrical signal, which is transmitted to the control unit of the detection system in real time through the data transmission line.

[0026] like Figure 3 and Figure 4 As shown, the upright 8 is fixed at a perpendicular angle to the tabletop at the upper end of the supporting table body 1. Multiple ball bearings 10 are fitted into the inner wall of the sleeve frame 6. The ball bearings 10 are tightly fitted into the upright 8. The circular plate 12 and the stainless steel spring 13 are fitted into the inner position of the groove 11. Pulling the fixed handle 7 outward causes the circular plate 12 and the stainless steel spring 13 to move in the inner position of the groove 11.

[0027] Multiple ball bearings 10 are fitted inside the socket frame 6. When the socket frame 6 moves up and down along the upright 8, the ball bearings 10 rotate at the position of the outer wall of the upright 8, which increases the flexibility of the socket frame 6.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
