Technical Field

[0001] The utility model relates to the technical field of length measurement, in particular to a part length testing device. Background Art

[0002] Parts come in a variety of shapes, such as parts with bends. Conventional rulers are difficult to meet the length measurement needs. Therefore, a circular ruler began to appear. The length of the part is calculated by the number of circles the disc structure rolls along the length direction of the part.

[0003] When measuring parts with curved surfaces, such as pipes, current circular rulers have difficulty maintaining stability during movement, which can easily cause the circular ruler to tilt during forward movement, resulting in increased measurement errors. Utility Model Content

[0004] The utility model aims at at least solving the problem of lack of auxiliary supporting mechanism in the prior art to provide stability.

[0005] The present invention provides a part length testing device, which is achieved by the following specific technical means: comprising an adjustment frame and measuring disks arranged on both sides of the adjustment frame, the peripheral sides of the measuring disks are provided with scales, and the adjustment frame is used to adjust the distance between the two groups of measuring disks, and the walking stability is good when the distance between the two groups of measuring disks becomes larger.

[0006] Preferred technical solution 1: The adjustment frame includes a wheel seat rotatably mounted on the central axis of the measuring disk, and convex seats are symmetrically fixed on both sides of each group of the wheel seats, and connecting rods are hingedly connected to the convex seats, and the connecting rod ends close to each other on the two groups of the wheel seats are hingedly connected.

[0007] Preferred technical solution two: the adjustment frame also includes an operating frame, and a pin shaft 1 is rotatably installed at the front end of the operating frame. At the same time, a slider is slidably provided at the middle and rear ends of the operating frame, and a pin shaft 2 is rotatably installed on the slider. The two groups of connecting rod ends located on the front side are hingedly connected through the pin shaft 1.

[0008] Preferred technical solution three: an adjusting screw is rotatably arranged on the operating frame, and the sliding block is sleeved on the adjusting screw through a threaded hole.

[0009] Preferred technical solution four: the adjustment frame is a U-shaped frame, and the width of the middle hole is greater than the diameter of the central axis of the detection disk.

[0010] The above structure enables this solution to have the following beneficial effects:

[0011] 1. The stability of walking measurement can be improved by setting two sets of measuring discs, which can avoid the situation that the track of a single set of measuring discs is easily skewed when moving, especially when measuring the length of pipe column parts;

[0012] 2. The distance between the two sets of measuring discs can be adjusted according to product conditions and stability requirements by using the setting of the adjustment frame;

[0013] 3. Measure the distance between the two sets of measuring discs by adjusting the rack, so as to minimize the volume when storing. BRIEF DESCRIPTION OF THE DRAWINGS
