And then observing whether the detection arc opening 38 of the detection plate 30 is attached to the surface of the workpiece or not, wherein if the detection arc opening is attached, the center height of the workpiece is qualified, and otherwise, the workpiece is unqualified. And then, after the limiting plate 34 is pressed downwards to overcome the elasticity of the return spring, the sliding rod 31 and the lifting plate 32 drive the detection bolt 33 to move downwards, and when the detection bolt 33 moves downwards and can be inserted into the assembly hole of the workpiece support, the assembly hole of the workpiece support is qualified, otherwise, the assembly hole is unqualified. After the lifting plate 32 moves downwards for a certain distance and the limiting plate 34 is released, the limiting plate 34 and the detection bolt 33 can be reset under the action of the elastic force of the reset spring. After the detection bolt 33 is reset, the detection sliding column 29 is pushed to move towards the handle of the workpiece. In the process, if the handle can be inserted into the transverse detection groove 39 of the detection sliding column 29, and the width of the inserted handle is longitudinally consistent with that of the notch 40, the assembly of the workpiece handle is qualified, otherwise, the workpiece handle is an unqualified product. The size detector 3 detects the assembly size of the workpiece, records the detection result, releases the clamping plate 37 to be separated from the clamping seat 35, and pushes the sliding frame 28 to reset.

The device for detecting the sliding force and the assembly size of the automobile steering gear detects the sliding force and the assembly size of the workpieces on the workpiece clamping device 2, and then the detected workpieces are disassembled; subsequently, a new workpiece is loaded on the group of workpiece clampers 2, and in this process, after the workpieces on the other group of workpiece clampers 2 are subjected to the slip force detection, the corresponding dimension detectors 3 are subjected to the assembly dimension detection. And then the device for detecting the sliding force and the assembly size of the automobile steering device can enter the next working cycle.

In the above process, the axial sliding force detection mechanism 6 and the workpiece complete the axial sliding force process as follows; firstly, a pulling pressure cylinder A16 drives a sliding seat 17 to move downwards through a pulling pressure sensor 18, when a clamping jaw 20 on the sliding seat 17 corresponds to a detection adapter 8 on a workpiece, an air cylinder 19 acts to clamp and fix the detection adapter 8 through the clamping jaw 20, and a rear pulling pressure cylinder A16 drives the sliding seat 17 to move upwards for a certain distance through the pulling pressure sensor 18; the stress recorded by the pulling pressure sensor 18 in the process is axial sliding force; the pulling cylinder A16 drives the sliding seat 17 to move upwards to a designated position through the pulling pressure sensor 18; the sliding seat 17 is driven by the pulling cylinder A16 to move downwards to reset the workpiece; then the clamping jaw 20 releases the detection adapter 8 and pulls the pressing cylinder A16 to reset; so far, the axial sliding force detection mechanism 6 will complete the axial sliding force of the workpiece.

In the above process, the angular sliding force detection mechanism 7 and the workpiece correspondingly complete the angular sliding force process as follows; firstly, pulling a pressure cylinder B23 to drive a shifting fork 24 to move upwards; when the clamping ring groove 42 on the detection adapter 8 falls into the inner part of the fork opening of the toggle fork 24, the toggle fork 24 stops acting, and at the moment, the limiting cylinder 26 can drive the upper limiting rod 27 to act to seal the fork opening of the toggle fork 24. Thus, the poking fork 24 can be connected with the detection adapter 8 in a clamping way through the lower limiting rod 25 and the upper limiting rod 27. And then the rear pulling cylinder B23 drives the shifting fork 24 to move downwards for a certain distance and then move upwards to drive the workpiece to reset. In the process that the pulling cylinder B23 drives the shifting fork 24 to move downwards, the shifting fork 24 can drive the upper column tube of the workpiece to synchronously rotate, and the stress detected by the pulling pressure sensor 18 is the axial sliding force of the workpiece. After the workpiece is reset, the limiting cylinder 26 drives the upper limiting rod 27 to reset, the fork opening of the shifting fork 24 is opened, then the rear pull pressure cylinder B23 drives the shifting fork 24 to reset, the angular sliding force detection mechanism 7 completes the angular sliding force detection of the workpiece completely, and the angular sliding force detection mechanism 7 can enter the next working cycle.
