Description

Technical Field

[0001] The utility model relates to the technical field of mechanical measurement, in particular to a measuring tool with extremely poor contour of a measuring surface. Background Art

[0002] During the anti-collision beam inspection process, many products require the detection of the extreme difference in the surface profile of the two brackets. Currently, a gap gauge is used to measure the distance between the two brackets and the inspection surface, and then the detection values ​​are subtracted to obtain the extreme difference in the surface profile of the two brackets.

[0003] However, this current detection method has two drawbacks: First, the detection efficiency is low and cannot meet the existing production capacity needs; second, the detection location is relatively limited and the maximum range cannot be detected, which affects the detection results. Utility Model Content

[0004] The main purpose of the utility model is to provide a gauge for measuring extremely poor surface contour, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A gauge for measuring extreme differences in surface contour comprises a lower connecting frame plate, wherein the four corners of the lower end of the lower connecting frame plate are fixedly connected to self-locking pulleys, the four corners of the upper end of the lower connecting frame plate are fixedly connected to connecting rods, the upper ends of the four connecting rods are commonly fixedly connected to the upper connecting frame plate, the upper end of the upper connecting frame plate is fixedly connected to several mounting blocks, and the upper ends of the several mounting blocks are commonly fixedly connected to a fixing plate.

[0007] The two cams have the first pivot place and the second pivot places, a space is defined between the left and right sides of the two cams, and the two cams have a hinge part, on which the two cams are connected, and a check valve is placed on the top of the cam.

[0008] Preferably, the mounting block is fixedly connected to the upper connecting frame plate and the fixing plate by bolts.

[0009] By adopting the above technical solution: the bolt connection is firm and reliable, easy to install and disassemble, conducive to maintenance and replacement of parts, ensuring the stability of the inspection fixture structure, and improving inspection accuracy and work efficiency.

[0010] Preferably, a buffer pad is provided at the clamping point between the clamping plate and the first fixing rod.

[0011] By adopting the above technical solution, the buffer pad at the connection between the clamping plate and the first fixing rod can reduce the impact force during the connection, reduce wear and noise, enhance the connection stability, extend the service life of the components, make the inspection tool run more smoothly, and ensure the accuracy and reliability of the test results.

[0012] Preferably, the surface of the clamping column is hardened.

[0013] By adopting the above technical solution: the surface hardness and wear resistance can be enhanced, deformation and damage are not easy to occur, the stability and reliability of the column connection can be improved, the service life of the inspection fixture can be extended, and the accuracy and efficiency of the inspection work can be ensured.

[0014] Preferably, a shock-absorbing pad is provided between the base and the fixing plate.

[0015] By adopting the above technical solution, the vibration during the detection process can be effectively absorbed, the noise can be reduced, the structural stability can be enhanced, the components can be protected, the detection accuracy can be improved, and the service life of the inspection tool can be extended.

[0016] Preferably, the surface of the handle is provided with anti-slip textures.

[0017] By adopting the above technical solution: the friction force can be increased to prevent hand slipping during operation, so that the inspector can control the inspection block more stably, ensure the accuracy of the inspection action, improve the inspection efficiency, and ensure the smooth progress of the inspection work.

[0018] Preferably, a reinforcing rib is provided at the connection position between the guide column fixing seat and the connecting block.

[0019] By adopting the above technical solution: the connection strength can be enhanced, deformation can be prevented, the guide column can be fixed more firmly, the detection block can be moved accurately, and the reliability and detection accuracy of the inspection fixture can be improved.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In the present invention, the inspection fixture with extremely poor measuring surface contour significantly optimizes the inspection process and greatly improves the inspection efficiency. Traditional inspection methods are usually time-consuming and labor-intensive, and it is difficult to meet the rapidly growing production capacity needs. However, after placing the parts in a specific position and completing a series of fixed operations, the operator only needs to push the inspection block to move it along the guide column to quickly obtain the inspection results. The self-locking pulley facilitates the flexible movement and precise positioning of the inspection fixture, saving time in adjusting the position of the equipment. The stable combination of the various connecting components ensures the smoothness and accuracy of the inspection action, and avoids delays caused by loose or unstable components. This rapid inspection capability greatly increases the speed of part inspection on the production line, effectively guarantees production progress, and meets the requirements of efficient production in modern industry.

[0022] 2. In the present invention, the inspection tool for measuring the extreme difference of surface contour can perform comprehensive and accurate extreme difference detection on all positions of the inspected surface, thereby significantly improving the accuracy of the test results. In traditional testing, due to the limitations of the detection means, only partial positions can be detected, and it is difficult to cover the entire inspected surface, resulting in deviations and omissions in the test results. However, this inspection tool can reach every corner of the inspected surface through its unique structural design, such as flexible guide columns and movable detection blocks. The operator can easily move the detection block to any position that needs to be inspected to ensure that nothing is missed. At the same time, the coordinated use of reference points, reference pins and clamps can stably fix the parts to avoid errors caused by shaking or displacement of parts during the detection process.

If the stop gauge can be inserted, the position is considered unqualified; if not, the position is considered qualified. Throughout the inspection process, the lower connecting frame 1 provides basic support, and the self-locking pulley 2 facilitates movement and positioning of the device.
