[0034] During the production process, workpieces will deform for various reasons. Whether they are metal parts or plastic parts, deformation is inevitable during the production process. The amount of workpiece deformation directly affects the functions of mechanical equipment after assembly. Therefore, before assembly, it is necessary to perform dimensional inspections on the produced workpieces, such as length and width inspections, perpendicularity inspections, etc. When performing dimensional inspections on workpieces, since multiple points need to be inspected to ensure the accuracy of the inspection results. However, most current inspection devices are equipped with a dial indicator on the side of each point to be measured for measurement. There are many dial indicators set, resulting in high costs. Moreover, most inspection devices can only inspect one side at a time. To inspect the other side, the workpiece needs to be repositioned, which takes a lot of time, has low efficiency, and slow inspection speed.

By providing the first moving component 300 and the second moving component 400, the first moving component 300 can drive the first detecting component 500 to move along the first direction, and the second moving component 400 can drive the second detecting component 600 to move along the second moving direction. That is, only one detecting component needs to be provided for measuring different points in the same direction, and there is no need to provide multiple detecting components at multiple points, so that the measurement of different points of the object in the same direction can be realized, and the manufacturing cost is saved. Moreover, by providing two moving components to drive two detecting components to move and detect respectively, the detection of different points in two directions of the object to be measured can be realized, the measurement efficiency is improved, and the measurement time is saved.

The first detecting component 500 continuously contacts the object to be measured in this direction, performs multi-point measurement on the object to be measured, and measures the length of the object to be measured.

[0039] In this embodiment, the second moving component 400 includes a second guide rail 410 and a second slider 420. The second guide rail 410 is arranged on the surface of the base 100, and the second slider 420 is slidably connected to the second guide rail 410; the second detecting component 600 is connected to the second slider 420. The second guide rail 410 extends along the second direction Y, and the second slider 420 moves along the second guide rail 410, thereby driving the second detecting component 600 to move along the second guide rail 410. The second detecting component 600 continuously contacts the object to be measured in this direction, performs multi-point measurement on the object to be measured, and measures the width of the object to be measured.

[0040] The friction coefficient between the guide rail and the slider is low, and the frictional resistance is small, enabling smooth movement, reducing impacts and vibrations during movement.

[0043] To adjust the height of the base 100 according to the detection needs for the convenience of the operator, please continue to refer to Figure 1 and Figure 2 , the detection device 1000 in this embodiment further includes base support columns 700.

Specifically, the number of base support columns 700 in this embodiment is four, and the four base support columns 700 are respectively arranged at the four corners of the base 100. Of course, the number of base support columns 700 can also be one, two, three, six, eight, etc., which is determined according to the actual situation and is not limited herein. When there is only one base support column 700, the diameter of the base support column 700 should be designed to be larger to support the entire base 100. The diameter of the base support column is determined according to the set number as long as it can ensure the stability of the entire base.

[0044] Specifically, the base 100 in this embodiment is provided with a mounting hole 110, and the base support column 700 is connected to the base 100 through the mounting hole 110. By adjusting the length of the base support column 700 extending out of the mounting hole 110 and locking the position with a nut, the height of the base 100 can be adjusted. In addition, an adjusting screw rod and a support seat can also be provided on the base support column 700. One end of the adjusting screw rod is connected to the support seat, and the other end of the adjusting screw rod is threadedly connected to the bottom of the base support column 700.

In order to ensure the stable placement of the base 100, an anti-slip pad can also be provided at the bottom of the support seat.

[0045] In order to ensure the accuracy of detection and improve the detection precision, the first detection member 500 in this embodiment is a first dial indicator, and / or the second detection member 600 is a second dial indicator.

Of course, the first detection member 500 and the second detection member 600 can also be other detection instruments such as a laser rangefinder, an electronic ruler, etc., which is not limited herein and is determined according to the actual measurement precision requirements and manufacturing costs.

[0046] According to a detection device 1000 provided by this embodiment, its working principle is as follows:

[0047] When it is necessary to detect the length and width of the object to be measured, the object to be measured is placed on the stage 800, and the positioning posts limit the movement of the object to be measured along the first direction X and the second direction Y. The first detection member 500 contacts the object to be measured and starts to measure. Then, the first detection member 500 is driven by the first moving assembly 300 and moves along the first direction X to measure the length of the object to be measured and perform multi-point detection on the contact surface. The second detection member 600 contacts the object to be measured and starts to measure. Then, the second detection member 600 is driven by the second moving assembly 400 and moves along the second direction Y to measure the width of the object to be measured and perform multi-point detection on the contact surface. The object to be measured can measure the dimensions in two directions without being re-placed, saving manpower, improving the detection efficiency, and saving the detection time. In addition, the detection device 1000 can set only one detection member for measurements at different points in the same direction, saving the manufacturing cost.
