Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0024] The invention discloses a method for detecting the load state of a lead screw transmission mechanism, comprising the following steps:

[0025] S1. Connect the connector 2 at one end of the lead screw 1, and connect the other end of the connector 2 with the driving device 3 with a torque gauge;

[0026] S2. Drive the connecting piece 2 to rotate through the driving device 3, and the connecting piece 2 drives the lead screw 1 to rotate. The driving device 3 displays the value through the transmission torque, collects the torque value through the torque meter, and compares the multi-point measurement data with the equipment control parameters. , the location where the data value is abnormal is the exact location of the fault point to find out the fault point.

[0027] Specifically, by us...

Abstract

The invention belongs to the technical field of lead screw load rate detection, and particularly discloses a detection method for the load state of a lead screw transmission mechanism, which comprises the following steps that one end of a lead screw is connected with a connecting piece, and the other end of the connecting piece is connected with a driving device; the driving device drives the connecting piece to rotate, the connecting piece drives the lead screw to rotate and move, the measuring type torque wrench can measure the torque value of any point in the moving process of the lead screw, the torque value is collected through the torque meter, multi-point measurement data is subjected to drawing analysis and compared with equipment control parameters, the part with the abnormal data value is the accurate position of a fault point, and the fault point is found out. The invention further discloses a detection device which comprises a connecting piece and a driving device, the size change of a torque value is visually seen through the torque meter of the torque wrench, multi-point measurement data is subjected to drawing analysis and compared with equipment control parameters, and then fault points can be quickly and accurately found out. And predictive detection of the transmission fault of the numerical control equipment is realized.

Description

technical field [0001] The invention belongs to the technical field of detection of the load rate of a lead screw, and specifically discloses a detection method and a detection device for the load state of a lead screw transmission mechanism. Background technique [0002] At present, the load rate detection technology of the coordinate axis lead screw transmission device of CNC equipment is generally implemented by professional technical manufacturers using special software. The detection cost is high, the detection cycle is long, or the servo shaft transmission mechanism is detected by using special instruments. The above special detection instruments are all It requires professionals to use, and has very high requirements on the testing environment, so it is not suitable for commissioning and maintenance of on-site equipment. Contents of the invention [0003] The object of the present invention is to provide a detection method and a detection device for the load state o...
