Description

Technical Field

[0001] This utility model relates to the field of planar inspection technology, and in particular to a planarity inspection fixture. Background Technology

[0002] After production, all parts need to undergo dimensional inspection to ensure that the product meets design requirements. Currently, high-precision inspection of parts is generally carried out using large coordinate measuring machines (CMMs). This type of inspection is very accurate, but the operation is cumbersome, requiring manual inspection of each part one by one, and each inspection takes a long time. For some small enterprises or parts with only a few precision requirements, such as rotary shaft parts, only the overall height and flatness are required. Therefore, using a CMM for such parts is very cumbersome. They usually use calipers to inspect them manually. However, calipers can only measure height, and cannot measure flatness.

The detection component is detachably connected to the transmission component. The first driving component drives the detection component to move up / down through the transmission component. The rotating part includes a second drive assembly and a turntable assembly installed at the output end of the second drive assembly, and also includes a sliding part, wherein the turntable assembly drives the part located in the sliding part to rotate.

[0004] Furthermore, a height detection unit is also installed on the frame body; the height detection unit includes a support frame and a sensor installed on the support frame, the sensor being used to measure the height of the part.

[0005] Furthermore, the turntable assembly includes a turntable rotatably connected to the frame body, the turntable having teeth on its circumferential side, a contour block on the top of the turntable, parts fixed within the contour block, and a gear meshing with the teeth fixed at the output end of the second drive assembly, the second drive assembly driving the turntable to rotate via the gear.

[0006] Furthermore, the sliding part includes a base plate fixedly connected to the frame body and several sets of cover plates fixedly connected to the base plate. The base plate is provided with several sets of grooves, and several sets of spheres are provided in the grooves. The cover plates are used to cover the grooves, and the spheres rotate within the cover plates and grooves.

[0007] Furthermore, the transmission assembly includes at least two sets of support seats and a lead screw disposed between the two sets of support seats. A slide rail is also provided below the lead screw, and a slider is slidably connected on the slide rail. The slider is connected to the lead screw through a lead screw nut.

[0008] Furthermore, the detection component is a dial indicator.

[0009] Furthermore, the first drive component and the second drive component are motors.

[0010] The flatness testing fixture provided by this utility model has the following advantages: This invention fixes the part on the turntable by a contour block. A laser sensor is set on one side of the turntable. The height of the part can be determined by the laser return time. There is no physical contact, the detection accuracy is high, and the height of multiple positions in the plane can be detected by rotating the turntable. On the other side of the frame body is a lead screw motor assembly. The lead screw drives the dial indicator to move up and down. After the adjustment is completed, the turntable rotates. By observing the movement of the dial indicator, the flatness of the entire surface can be quickly seen. It is simple and direct. With the help of the production line, a worker can complete the inspection of the height and flatness of a part in a dozen seconds, improving production efficiency. Attached Figure Description
