Description

Technical Field

[0001] The utility model relates to the technical field of coating thickness measurement, in particular to a broach coating thickness measuring device. Background Art

[0002] A broach is a forming tool used for broaching. There are multiple rows of teeth on the surface of the tool. The size and shape of each row of teeth increase and change from the cutting end to the cutting end. Before using the broach, its surface needs to be coated to extend its service life. After the coating of the broach is completed, the coating thickness needs to be tested on its surface to avoid excessive thickness and affect subsequent use.

[0003] However, the following problems still exist in actual use:

[0004] The existing detection is performed by laser scanning. The existing detection directly places the broach on the workbench. This method cannot form a three-dimensional scan of the broach, and can only perform single-sided detection on the broach. The detection process is cumbersome and requires manual replacement of the detection surface of the broach, which affects the detection efficiency. At the same time, during the broach detection process, its position cannot be limited, which leads to displacement during the detection process, affecting the detection accuracy.

The surface of the connecting plate is rotatably connected to a hinge block, and the hinge block is fixedly connected to the sliding plate.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. By providing a carrying platform, the broach is placed vertically on the top of the carrying platform. At this time, according to the model of the broach, the connecting arm is manually rotated to drive the position of the abutment block to move, so that the spacing between the two abutment blocks matches the size of the broach. When the broach is fixed, the second drive motor is started to drive the control plate to rotate. At this time, the rotating control plate will drive the connecting plate to move, and the traction force of the end of the control plate is applied to the connecting plate, thereby driving the sliding plate to move inside the installation groove 1, thereby driving the two abutment blocks on the top of the carrying platform to move in different directions, so as to realize the rapid clamping and fixing of the pull. During the use of the device, it is only necessary to pre-adjust the position of the abutment block before the coating inspection of the broaches of the same batch. Subsequently, the abutment block can be driven to move by the second drive motor to quickly clamp and fix the broach, which greatly improves the work efficiency and convenience.

[0012] 2. By setting up a laser tester, during detection, the electric telescopic rod is started to drive the connecting arm to move up and down inside the empty slot, and then the position of the detection cover is driven to move up and down, and then the laser tester scans the surface of the broach up and down. At the same time, the first drive motor drives the support platform to rotate, and then drives the broach to rotate, so that the laser tester can scan the surface of the broach without blind spots. The device greatly improves the speed of detecting the coating thickness on the surface of the broach and the accuracy of the data through three-dimensional laser scanning detection of the broach surface without blind spots.
