[0002] The electrolytic coating thickness gauge is used to measure the thickness of the coating on the surface of the workpiece, and generally includes a host and a test bench structure. The constant current source on the host is connected to the cathode plug and the anode clamp, and the stirring source is connected to the stirring head. The test bench structure generally includes a base, a V-shaped block placed on the base, a connecting rod fixed to the base, a beam that can be adjusted up and down at the fixed position of the connecting rod, an electrolytic cup set on the beam, and a cathode conductive head connected to the electrolytic cup. The beam is fixed to the connecting rod by bolts, that is, the operation of adjusting the beam up and down at the fixed position of the connecting rod is: after loosening the bolt, move the beam up and down to adjust the position, and tighten the bolt again after the adjustment is completed. The workpiece to be measured is placed on the V-shaped block; adjust the beam downward at the fixed position of the connecting rod so that the probe is against the surface of the workpiece; insert the cathode plug into the cathode conductive head, and clamp the anode clamp on the workpiece; use a dropper to inject an appropriate amount of liquid into the electrolytic cup, and the contact position between the probe and the workpiece cannot leak; insert the stirring head into the electrolytic cup. The existing test bench structure still has the following problems: it is inconvenient to adjust the beam up and down in the fixed position of the connecting rod, especially when the beam is moved down to the electrolytic cup and the probe is against the workpiece, it is difficult to control the beam, and the probe and the workpiece are not pressed tightly enough, there will be leakage, and the test cannot be carried out; if they are pressed too tightly, the probe will be deformed too much, which will affect the test results.

[0014] See also Figure 2 and Figure 5 A test bench structure of an electrolytic coating thickness gauge includes a base 1, a V-shaped block 2, a connecting rod 3, a crossbeam 4, an electrolytic cup 5, a cathode conductive head 6 and an adjustment mechanism 7.

[0015] The V-shaped block 2 is placed on the top surface of the base 1 for placing the workpiece.

[0016] The bottom position of the connecting rod 3 is fixedly connected to the rear position of the base 1. More specifically, the bottom of the connecting rod 3 may have a section of thread, which is threadedly connected to the base 1.

[0017] The rearward position of the cross beam 4 is fixedly connected to the connecting rod 3, and the fixed position can be adjusted in the up-down direction.

[0018] The adjustment mechanism 7 is disposed between the cross beam 4 and the connecting rod 3 and is used for adjusting the fixed position of the cross beam 4 .

[0019] See also Figure 2 , Figure 3 and Figure 4In some embodiments, the adjustment mechanism 7 includes a rack 7a, a gear 7b and a magnet 7c. The rack 7a is fixedly connected to the connecting rod 3. More specifically, the connecting rod 3 may be provided with a plurality of notches to form a rack 7a. The gear 7b is rotatably connected to the crossbeam 4. More specifically, a hole for the connecting rod 3 to pass through is provided at the rear position of the crossbeam 4, and a groove connecting the hole and the outside is also provided. The gear 7b is in the groove, and the shaft 7b1 is used to pass through the part of the crossbeam 4 on both sides of the groove and the gear 7b. The gear 7b rotates together with the shaft 7b1, and one end of the shaft 7b1 may have a hand screw head to facilitate manual rotation of the gear 7b. The gear 7b is meshed with the rack 7a. Manual rotation of the gear 7b can drive the crossbeam 4 to move up and down. The magnet 7c is fixedly connected to the beam 4 and can magnetically attract the connecting rod 3, that is, without rotating the gear 7b, the beam 4 is adsorbed and fixed on the connecting rod 3 by the magnet 7c; when the gear 7b is rotated, the magnet 7c remains adsorbed on the connecting rod 3, and the beam 4 moves up and down with damping. After the gear 7b stops rotating, the beam 4 remains in the adjusted position.

The connecting rod 3 is provided with an external thread, which is matched with the screw nut 7e. Correspondingly, a vertical optical axis 7b1 can be fixedly connected to the base 1 to guide the crossbeam 4 and limit the rotation of the crossbeam 4 around the connecting rod 3. By rotating the screw nut 7e, the crossbeam 4 can be driven to move up and down, and the crossbeam 4 is fixed to the connecting rod 3 by utilizing the self-locking between the screw nut 7e and the external thread.

[0021] See also Figure 6 Furthermore, the arrangement for limiting the rotation of the cross beam 4 around the connecting rod 3 can also be: there is at least one notch on the connecting rod 3 to form the vertical plane 3a, that is, the cross section of the connecting rod 3 changes and is no longer circular, and the hole on the cross beam 4 for the connecting rod 3 to pass through also changes with the change of the cross section of the connecting rod 3. More specifically, there can be two notches, and the two vertical planes 3a formed are opposite to each other. There is no need to set up an additional optical axis 7b1, and the structure is simpler.

[0022] See also Figure 2 and Figure 4, the electrolytic cup 5 is fixedly connected to the front position of the cross beam 4, and the bottom passes through the cross beam 4. More specifically, the electrolytic cup 5 includes a cup body 5a and a probe 5b, the cup body 5a is made of a conductive material, and the probe 5b is made of a material that can reset the deformation, generally rubber; a hole for the cup body 5a to pass through and be fixed is provided at the front position of the cross beam 4, and the probe 5b is installed in the cup body 5a, which exceeds the bottom surface of the cross beam 4.

More specifically, a threaded hole with an internal thread is also provided at the front position of the cross beam 4, and the threaded hole is connected to the hole through which the cup body 5a passes and is fixed. The cathode conductive head 6 is threadedly connected to the threaded hole and abuts against the cup body 5a of the electrolytic cup 5.

[0024] See also Figure 1 When the test bench structure of the electrolytic coating thickness gauge is in use, the workpiece to be measured is placed on the V-shaped block 2; the crossbeam 4 is adjusted downwardly at the fixed position on the connecting rod 3 so that the probe 5b is against the surface of the workpiece; the constant current source of the host of the electrolytic coating thickness gauge is connected to the constant current line, the cathode plug 10 is inserted into the cathode conductive head 6, and the anode clamp 9 is clamped on the workpiece; a proper amount of liquid medicine is injected into the electrolytic cup 5 with a dropper, and the contact position between the probe 5b and the workpiece cannot leak; the stirring source of the host of the electrolytic coating thickness gauge is connected to the stirring head 8, and the stirring head 8 is inserted into the electrolytic cup 5.
