Description

Technical Field

[0001] This utility model belongs to the field of mechanical fixture technology, and in particular relates to a gauge for measuring flatness and height. Background Technology

[0002] In the field of machining, there are basic requirements for dimensional accuracy and positional accuracy. For example, products that need to be spliced ​​together require flatness and perpendicularity, while products that require circular insertion require dimensional accuracy and coaxiality. Therefore, after the production of different product parts is completed, the products need to be inspected according to the design parameters. Currently, in inspection, plug gauges or probe measuring instruments are generally used to measure flatness, and height gauges are generally used to measure height. Although these measurement methods can be used, for a large number of products to be inspected, the measurement speed of flatness measuring equipment is relatively slow. For the standard flatness accuracy requirements, the measurement time is very long and the efficiency is low. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0004] A gauge for measuring flatness and height includes a frame body, a fixing assembly disposed on the frame body, a first measuring assembly for measuring flatness, and a second measuring assembly for measuring height;

[0005] The fixing assembly includes a first slide rail fixed to the frame body and a loading tray that slides on the first slide rail. At least two sets of fixing members are also slidably connected on the first slide rail. The fixing members are respectively disposed on both sides of the loading tray, and the fixing members are used to fix parts on the loading tray.

[0006] The first measuring component includes at least two sets of measuring brackets, which are arranged opposite each other. Each set of measuring brackets is provided with a driving element. The output end of the driving element is connected to a driving component. A first measuring unit is fixedly connected to the driving component. The measuring bracket is also provided with a guide block. The driving component slides up / down in the guide block. When the driving element moves up / down, it can drive the first measuring unit to move up / down.

[0007] The second measuring component includes a second slide rail fixed on the frame body and a measuring seat that slides on the second slide rail. A second measuring unit is fixedly connected to the measuring seat. The frame body is provided with a through hole for accommodating the second measuring unit.

[0008] Furthermore, the measurement unit is an infrared measurement module, wherein the transmitting end is located on any one of the driving components of the first measurement component, and the receiving end is located on another set of driving components. The receiving end and the transmitting end are arranged opposite each other and are located on the same horizontal line.

[0009] Furthermore, the fastener includes a base and a pressure end and a fixing end rotatably connected to the base. When the pressure end is pried up / down, the product on the tray can be pressed / released by the fixing end.

[0010] Furthermore, the second measuring unit is a height gauge, and the through hole is used for the probe of the height gauge to pass through.

[0011] Furthermore, the driving element is a cylinder.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model can quickly fix parts by using a sliding tray and fixing parts, and move them back and forth synchronously. The tray is equipped with infrared measurement modules on both sides, one as a transmitter and the other as a receiver. When in use, the infrared measurement module is adjusted to the plane to be measured. At this time, the receiver can receive the signal from the transmitter in real time and push the tray to move back and forth. If the flatness is insufficient, the receiver will generate intermittent receiving signals, which can verify whether the flatness is qualified. It can quickly detect whether the flatness of the product is qualified, thus improving the efficiency of flatness measurement.

[0014] 2. This utility model also includes a height gauge in the height direction, which can measure the height of the part while measuring the flatness, thereby improving the measurement speed. The height and flatness can be measured in one clamping, improving measurement efficiency and reducing measurement costs. Attached Figure Description
