Description

Technical Field

[0001] This utility model relates to the field of speed reducer manufacturing technology, and in particular to a wear-resistant coating anti-scratch testing device for speed reducer housings. Background Technology

[0002] A speed reducer is an independent component consisting of gear drives, worm drives, or gear-worm drives enclosed in a rigid housing. It is commonly used as a speed reduction transmission device between a prime mover and a driven machine. It plays a role in matching speeds and transmitting torque between the prime mover and the driven machine or actuator, and its applications are extremely widespread in modern machinery.

[0003] Gearbox housings are generally manufactured by casting and then machined. To meet the requirements of extending service life and ensuring internal sealing, anti-corrosion paint and anti-scratch coatings are usually applied to the exterior of the housing. To test the surface anti-scratch effect of the external coating, anti-scratch testing equipment is generally used to test the surface hardness of the coating on the outer housing. Existing testing equipment mainly uses reciprocating motion to generate friction and judges the surface hardness by the resulting scratches. However, the friction area is small, making the judgment difficult. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a device for detecting the wear-resistant coating and scratch resistance of a speed reducer housing.

[0005] This utility model is achieved through the following technical solution:

[0006] A wear-resistant coating anti-scratch testing device for a speed reducer housing includes a base, a push-pull mechanism, a friction mechanism, and a clamping knob. The push-pull mechanism is disposed on the upper surface of the base, the friction mechanism is engaged at the top of the push-pull mechanism, and the clamping knob is threadedly connected to one end of the base. The push-pull mechanism includes a mounting plate, a first hydraulic cylinder, a movable seat, a motor, a cam, a guide shaft, and a spring. The mounting plate is fixedly disposed on the top of one end of the base, the first hydraulic cylinder is disposed on the outside of the mounting plate, the movable seat is fixedly disposed on the telescopic end of the first hydraulic cylinder, the motor is mounted inside one side of the movable seat, the cam is mounted on the output end of the motor, a slot is provided at the bottom of the movable seat, the guide shaft is fixedly disposed in the slot at the bottom of the movable seat, and the spring is sleeved on the outside of the guide shaft.

[0007] In a preferred embodiment of this utility model, the friction mechanism includes a support base, a contact plate, a connecting shaft, a collar, an extension rod, a tool holder, a friction plate, a top plate, a second hydraulic cylinder, a pressure gauge, a retaining seat, and a pressure applying seat. The support base is clamped to the inner side of the bottom of the movable seat. The contact plate is fixed to one side of the support base. An installation groove is provided on the top of the support base. The connecting shaft is fixedly installed in the installation groove on the top of the support base. The collar is movably connected to the connecting shaft. The extension rod is fixedly installed on the surface of the collar. The tool holder is fixedly installed at the end of the extension rod. The friction plate is fixedly installed inside the tool holder. The top plate is fixedly installed on the top of the support base. The second hydraulic cylinder is fixedly installed on the top of the top plate. The pressure gauge is fixedly installed at the telescopic end of the second hydraulic cylinder. The retaining seat is fixedly installed at the bottom of the pressure gauge. The pressure applying seat is movably connected to the bottom of the retaining seat.

[0008] The friction mechanism mainly uses multiple second hydraulic cylinders to apply pressure to the corresponding extension rods to determine the depth of scratches produced by the friction plates on the surface of the reducer housing coating under different pressures, thereby determining the coating's scratch resistance.

[0009] In a preferred embodiment of the present invention, the bottom of the card holder is provided with a slot for cooperating with the extension rod, and the extension rod is locked in the slot at the bottom of the card holder;

[0010] The card holder designed for this activity effectively ensures a proper fit with the extension rod and prevents it from detaching from the extension rod during pressure application.

[0011] In a preferred embodiment of this utility model, the contact plate is fixedly disposed on the side of the support base adjacent to the motor, and the outer side of the cam contacts the surface of the contact plate;

[0012] After the motor starts, the cam on its surface rotates, pushing the contact plate on the side of the support base. With the help of the spring, the support base reciprocates, thereby increasing the scraping area of ​​the friction plate and making it easier to observe the work.

[0013] In a preferred embodiment of the present invention, the bottom of the support base is engaged in the inner groove of the bottom of the movable base, and the bottom of the support base has an insertion hole that mates with the guide shaft.

[0014] In a preferred embodiment of this utility model, a clamping groove is provided on the upper surface of the base;

[0015] The clamping slot is used in conjunction with the clamping knob to effectively clamp and fix the reducer housing.

[0016] The beneficial effects of this utility model are:

[0017] This gearbox housing wear-resistant coating anti-scratch testing equipment can test the anti-scratch capability of the housing anti-scratch coating by replacing friction pads of different hardness and applying different pressures to friction pads of the same hardness, and reciprocating on the surface of the anti-scratch coating. The equipment can not only reciprocate back and forth, but also has the ability to swing left and right to change the scratch area, thereby increasing the scratch area and facilitating observation and judgment.

The push-pull mechanism 2 includes a mounting plate 21, a first hydraulic cylinder 22, a movable seat 23, a motor 24, a cam 25, a guide shaft 26, and a spring 27. The mounting plate 21 is fixedly disposed on the top of one end of the base 1, the first hydraulic cylinder 22 is disposed on the outside of the mounting plate 21, the movable seat 23 is fixedly disposed on the telescopic end of the first hydraulic cylinder 22, the motor 24 is installed inside one side of the movable seat 23, the cam 25 is installed on the output end of the motor 24, a slot is opened at the bottom of the movable seat 23, the guide shaft 26 is fixedly disposed in the slot at the bottom of the movable seat 23, and the spring 27 is sleeved on the outside of the guide shaft 26.

[0025] Specifically, the friction mechanism 3 includes a support base 31, a contact plate 32, a connecting shaft 33, a collar 34, an extension rod 35, a tool holder 36, a friction plate 37, a top plate 38, a second hydraulic cylinder 39, a pressure gauge 310, a retainer 311, and a pressure application seat 312. The support base 31 is secured to the inner bottom of the movable seat 23. The contact plate 32 is fixed to one side of the support base 31. The top of the support base 31 has an installation groove. The connecting shaft 33 is fixedly installed in the installation groove at the top of the support base 31. The collar 34 is movably connected to the connecting shaft 33. The extension rod 35 is fixedly installed on the surface of the collar 34. The tool holder 36 is fixedly installed at the end of the extension rod 35. The friction plate 37 is fixedly installed inside the tool holder 36. The top plate 38 is fixed. The second cylinder 39 is fixedly mounted on the top of the top plate 38, and the pressure gauge 310 is fixedly mounted on the telescopic end of the second cylinder 39. The clamping seat 311 is fixedly mounted on the bottom of the pressure gauge 310. The pressure applying seat 312 is movably connected to the bottom of the clamping seat 311. The bottom of the clamping seat 311 has a groove that cooperates with the extension rod 35. The extension rod 35 is clamped in the groove at the bottom of the clamping seat 311. The contact plate 32 is fixedly mounted on the side of the support base 31 adjacent to the motor 24. The outer side of the cam 25 contacts the surface of the contact plate 32. The bottom of the support base 31 is clamped in the groove on the inner side of the bottom of the moving seat 23. The bottom of the support base 31 has an insertion hole that cooperates with the guide shaft 26. The upper surface of the base 1 has a clamping groove.

[0026] In this embodiment, the reducer housing to be tested is first placed flat-side up in the clamping groove on the upper surface of the base 1. Then, the clamping knob 4 is rotated to clamp and fix the reducer housing. Then, by rotating the collar 34 on the surface of the connecting shaft 33, the end of the friction plate 37 installed inside the tool holder 36 contacts the surface of the reducer housing. The second cylinder 39 at the top of the top plate 38 is controlled to extend, so that the bottom retainer 311 is engaged with the outside of the extension rod 35. According to the testing needs, different pressures are generated on the extension rod 35 by controlling different extension lengths of the second cylinder 39. The pressure value will be displayed on the pressure gauge 310. The retainer 311, which is movably set at the bottom of the pressure gauge 310, effectively ensures the fit with the extension rod 35.

[0027] Furthermore, by controlling the extension and retraction of the first hydraulic cylinder 22, the moving seat 23 at its end moves back and forth, thereby causing the friction plate 37 to move back and forth. At the same time, the motor 24 rotates, driving the cam 25 at its output end to rotate. The rotating cam 25 pushes the contact plate 32 on the side of the support seat 31, thereby causing the support seat 31 to move left and right under the guidance of the guide shaft 26 inside the moving seat 23. The spring 27 set at one end of the guide shaft 26 resets the support seat 31, thus realizing that the friction plate 37 can move left and right while moving back and forth, effectively increasing the scraping area of ​​the friction plate 37, thereby facilitating the work of judging the anti-scratch ability.
