Description

Technical Field

[0001] This utility model relates to the field of abrasion testing machine technology, and in particular to an abrasion testing machine for plug and pin insulation sheaths. Background Technology

[0002] The connectors of general electronic products and the pins of electrical appliances are called plugs. Household AC power plugs and sockets have male connectors that protrude in the shape of rods or copper plates, which are physically inserted into female connectors that have slots or recesses in the power socket.

[0003] Because plugs and pins require protective sleeves after production, and these sleeves are made of plastic, their abrasion resistance needs to be tested during production to ensure their quality. This requires an abrasion resistance testing machine. However, existing testing machines generate dust particles during abrasion testing, which can float in the air and cause harm if inhaled. Therefore, there is an urgent need for an abrasion resistance testing machine for plug and pin insulation sleeves to solve these problems. Utility Model Content

[0004] To solve the above problems, this utility model provides a plug pin insulation sheath abrasion resistance testing machine, which is achieved through the following technical solution.

[0005] A plug and pin insulation sheath abrasion resistance testing machine includes a base, a bracket fixedly connected to the top of the base, a hanging rod fixedly connected to one end of the bracket, a limit ring fixedly connected to one end of the hanging rod, a lifting plate movably connected to the other end of the hanging rod, a first servo motor fixedly connected to the bottom of the lifting plate, a grinding wheel fixedly connected to the output shaft of the first servo motor, a lifting seat movably connected to the bracket, and a plug model fixedly connected to the lifting seat. The machine also includes:

[0006] An annular suction pipe, with a suction hood connected through the top of the annular suction pipe;

[0007] A filter canister, the top of which is covered by a lid, the bottom of which is fixedly connected to a filter cover, and the top of which is connected to a flexible hose, and the filter canister is fixedly attached to a base.

[0008] An air pump, wherein the suction end of the air pump is connected through to the filter barrel and the air pump is fixed to the base.

[0009] Furthermore, the lifting rods are four in a ring, the spring fixed to the top of the lifting plate is sleeved on the lifting rods, and the first servo motor is movablely engaged with the limit ring.

[0010] Furthermore, the grinding wheel is located directly above the plug model, which is equipped with a three-pronged pin and a two-pronged pin, both of which are made of alloy material.

[0011] Furthermore, the annular suction pipe is fixedly connected to the top of the plug model, and one end of the hose is fixedly connected to the annular suction pipe and they are threaded together.

[0012] Furthermore, the filter barrel, barrel cover, and filter cover are all threaded together.

[0013] A second servo motor is fixedly connected to the bracket, and a lead screw is fixedly connected to the output shaft of the second servo motor. One end of the lead screw is connected through the lifting seat, and the lead screw is threadedly engaged with the lifting seat.

[0014] The beneficial effects of this invention are as follows: During operation, the device first places the test pin sleeve onto the pin on the lifting seat. Then, the second servo motor, the first servo motor, and the air pump are turned on. The second servo motor drives the lead screw to rotate, which in turn drives the threaded lifting seat to rise on the support, causing the pin sleeve on the plug model to adhere to the bottom of the grinding wheel. The first servo motor drives the grinding wheel to rotate, which grinds the pin sleeve, thus enabling a grinding test. The air pump draws air from the connected annular suction pipe through the filter bucket. The annular suction pipe, through the suction hood, draws the floating matter generated during grinding into the filter bucket, where it is filtered by the filter hood, preventing environmental pollution from the floating matter generated during grinding, thus achieving an environmentally friendly effect.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figure 1-4 As shown, the present invention has the following specific embodiments.

[0030] Example:

[0031] A plug and pin insulation sheath abrasion resistance testing machine includes a base 1, a bracket 11 fixedly connected to the top of the base 1, a hanging rod 12 fixedly connected to one end of the bracket 11, a limit ring 13 fixedly connected to one end of the hanging rod 12, a lifting plate 2 movably connected to the other end of the hanging rod 12, a first servo motor 22 fixedly connected to the bottom of the lifting plate 2, a grinding wheel 23 fixedly connected to the output shaft of the first servo motor 22, a lifting seat 4 movably connected to the bracket 11, a plug model 41 fixedly connected to the lifting seat 4, and further includes:

[0032] An annular suction pipe 5, with a suction hood 51 connected through the top of the annular suction pipe 5;

[0033] The filter canister 6 has a lid 61 covering its top, a filter cover 63 fixedly connected to the bottom of the lid 61, a flexible hose 62 passing through the top of the lid 61, and the filter canister 6 is fixedly attached to the base 1.

[0034] The suction end of the air pump 7 is connected through the filter barrel 6 and is fixed to the base 1.

[0035] Specifically, there are four hanging rods 12 arranged in a ring. The spring 21 fixed at the top of the lifting plate 2 is sleeved on the hanging rod 12. The first servo motor 22 is movably engaged with the limiting ring 13, which can limit the lifting of the first servo motor 22. When the first servo motor 22 is subjected to pressure, it can compress the spring 21. The compressed spring 21 can generate a reaction force, thereby giving the grinding a buffering effect.

[0036] Specifically, the grinding wheel 23 is located directly above the plug model 41, which is equipped with a three-pronged pin and a two-pronged pin. Both the three-pronged pin and the two-pronged pin are made of alloy material and can position the three-pronged pin sleeve and the two-pronged pin sleeve.

[0037] Specifically, the annular suction pipe 5 is fixedly connected to the top of the plug model 41, and one end of the hose 62 is fixedly connected to the annular suction pipe 5 and they are threaded together.

[0038] Specifically, the filter barrel 6, the barrel cover 61, and the filter cover 63 are all threaded together, which facilitates the disassembly and assembly of the filter barrel 6, the barrel cover 61, and the filter cover 63, and makes cleaning convenient.

[0039] Specifically, a second servo motor 3 is fixedly connected to the bracket 11, and a lead screw 31 is fixedly connected to the output shaft of the second servo motor 3. One end of the lead screw 31 is connected through the lifting seat 4, and the lead screw 31 is threadedly engaged with the lifting seat 4. The second servo motor 3 can drive the lead screw 31 to rotate, and the lead screw 31 can drive the lifting seat 4 to rise and fall, so as to drive the pin sleeve to fit against the grinding wheel 23 for grinding.

[0040] The working principle of this utility model:

[0041] When using the device, first, the plug sleeve to be tested is placed on the plug on the lifting seat 4. Then, the second servo motor 3, the first servo motor 22, and the vacuum pump 7 are turned on. The second servo motor 3 drives the lead screw 31 to rotate, and the lead screw 31 drives the threaded lifting seat 4 to rise on the bracket 11, so that the plug model 41 is fitted with the plug sleeve and attached to the bottom of the grinding wheel 23. The first servo motor 22 drives the grinding wheel 23 to rotate, and the grinding wheel 23 can grind the plug sleeve, thus enabling the grinding test of the plug sleeve. The vacuum pump 7 can evacuate air from the connected annular suction pipe 5 through the filter bucket 6. The annular suction pipe 5 can suck the floating matter generated by grinding into the filter bucket 6 through the suction hood 51. The filter bucket 6 filters through the filter cover 63 to avoid polluting the environment with floating matter generated by grinding, which has an environmental protection effect.
