[0004] The purpose of the present invention is to provide a screw detection device, which can solve the problem of how to measure the parallelism between the screw and the guide rail when there is a helical thread in the outer circle of the screw. In the process of moving the slider, the data measured by the dial indicator can directly detect whether the parallelism between the screw rod and the guide rail is out of tolerance, so as to directly measure the parallelism between the screw rod and the guide rail

Embodiment 1
[0054] A screw detection device, such as Figure 1 to Figure 3 as shown,
[0055] Including measuring tooling 1, dial indicator 2, and adjusting mechanism 3;
[0056] The measuring tooling 1 is arranged on the measuring end of the dial indicator 2;
[0057] The dial gauge 2 is located on the adjustment mechanism 3;
[0058] The adjustment mechanism 3 is arranged on the slider 5 of the guide rail 4, and is used to adjust the position of the dial indicator 2 and the measuring tool 1, so that when the parallelism between the screw mandrel 6 and the guide rail 4 is detected, the measuring tool 1 The measuring surface of the measuring surface fits the outer circle of the screw mandrel 6.
[0059] Through the screw detection device, the adjusting mechanism 3 is installed on the slider 5 of the guide rail 4, and the measuring tool 1 is installed on the measuring end of the dial indicator 2. During measurement, the adjusting mechanism 3 is used to adjust the position of the dial in...
Embodiment 2
[0076] A screw detection device, such as Figure 4 as shown,
[0077] Including measuring tooling 1, dial indicator 2, and adjusting mechanism 3;
[0078] The measuring tooling 1 is arranged on the measuring end of the dial indicator 2;
[0079] The dial gauge 2 is located on the adjustment mechanism 3;
[0080] The adjustment mechanism 3 is arranged on the slider 5 of the guide rail 4, and is used to adjust the position of the dial indicator 2 and the measuring tool 1, so that when the parallelism between the screw mandrel 6 and the guide rail 4 is detected, the measuring tool 1 The measuring surface of the measuring surface fits the outer circle of the screw mandrel 6.
[0081] The difference from Embodiment 1 is that, as Figure 5 As shown, the installation part 15 is disposed at one end of the measuring board 12 .
[0082] In the embodiment of the present invention, the mounting portion 15 is arranged at one end of the measuring plate 12, the mounting portion 15 and t...

Abstract
The embodiment of the invention belongs to the technical field of screw rod detection, and relates to a screw rod detection device and method. According to the technical scheme, the device comprises ameasuring tool, a dial indicator and an adjusting mechanism; the measuring tool is arranged at the measuring end of the dial indicator; the dial indicator is arranged on the adjusting mechanism; theadjusting mechanism is arranged on a sliding block of a guide rail and used for adjusting the positions of the dial indicator and the measuring tool. Therefore, the parallelism of a lead screw and theguide rail is detected. The measuring tool is attached to the outer circle of the lead screw. The adjusting mechanism is installed on the sliding block of the guide rail. During measurement, the positions of the dial indicator and the measuring tool are adjusted through the adjusting mechanism. In the process that the measuring tool is attached to the outer circle of the lead screw and the sliding block is moved, if the lead screw is not smooth or deforms within a certain distance, whether the parallelism of the lead screw and the guide rail is out of tolerance or not can be directly detectedthrough data measured by the dial indicator, and therefore the parallelism of the lead screw and the guide rail is directly measured.
Description
technical field [0001] The present application relates to the technical field of screw rod detection, and more specifically, to a screw rod detection device and method. Background technique [0002] The screw is a screw transmission element with steel balls as the rolling body between the screw and the nut. Its main function is to convert rotational motion into linear motion, or convert torque into axial repeated force. Due to its small frictional resistance It is widely used in various industrial equipment and precision instruments. If the screw rod fails, it will affect the use of industrial equipment and precision instruments. Inspection is performed to ensure the accuracy of the screw. [0003] After the screw rod is installed on the traditional machine tool, it is generally unknown whether the screw rod and the guide rail meet the parallelism requirements, but the linear guide rail is used as a reference, and the height of the screw rod at both ends of the bearing seat...
