Description

Technical Field

[0001] The utility model relates to the technical field of grinders, in particular to a windshield wiper motor shaft grinder. Background Art

[0002] The wiper motor shaft is a key component in the wiper motor. It plays a vital role in transmitting power and driving the wiper blades. It is typically made of high-strength metal materials, such as alloy steel, to ensure sufficient strength and wear resistance to withstand frequent rotation and loads over long-term use. Its shape and dimensions require precise design to perfectly coordinate with other motor components and the wiper blade connection mechanism, ensuring stable and efficient power transmission. A wiper motor shaft grinder is a device specifically designed for surface treatment of wiper motor shafts. This grinder removes burrs, imperfections, and oxide layers from the motor shaft, resulting in a smoother surface. This reduces friction and wear, thereby increasing the motor shaft's service life and operating efficiency.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1:

[0024] See also Figure 1-3 As shown, the utility model is a windshield wiper motor shaft grinder, comprising a machine body 1, a workbench 11 provided at the bottom of the machine body 1, a feed port 2 fixedly mounted on the top of the machine body 1, a feed channel 21 mounted at the bottom of the feed port 2, the width of the feed channel 21 being slightly larger than the diameter of the windshield wiper motor shaft, allowing only one windshield wiper motor shaft to pass through at a time, a plurality of grooves being formed on the side of the feed channel 21, each of which has a baffle 23 movably mounted in each of the grooves; a mounting plate 25 fixedly mounted at the bottom of the cover of the machine body 1, a plurality of electric telescopic rods 24 fixedly mounted on the mounting plate 25, and a baffle 23 fixedly mounted at the output end of each of the plurality of electric telescopic rods 24. By controlling the electric telescopic rods 24 to extend and retract the baffles 23 in the feed channel 21, the windshield wiper motor shaft can be ensured to pass through the feed channel 21 in an orderly manner;

[0025] A guide rail 3 is fixedly mounted on the workbench 11, a lifting platform 31 is slidably mounted on the guide rail 3, a first motor 32 is fixedly mounted on the top of the lifting platform 31, an electric chuck 33 is fixedly mounted on the end of the output shaft of the first motor 32, a mounting platform 4 is also fixedly mounted on the workbench 11, a guide rail 2 41 is fixedly mounted on the mounting platform 4, a mounting seat 42 is slidably mounted on the guide rail 2 41, a second motor 43 is fixedly mounted on the top of the mounting seat 42, and a polishing sleeve 44 is fixedly mounted on the end of the output shaft of the second motor 43. When the equipment is working, the lifting platform 31 is controlled to rise and fall so that the electric chuck 33 is aligned with the axis of the wiper motor shaft at the bottom of the discharge channel 21. The lifting platform 31 is controlled to slide so that the electric chuck 33 clamps the wiper motor shaft. Then the electric telescopic rod 1 24 is controlled to open the baffle 23 below the wiper motor shaft. The lifting platform 31 is then controlled to slide to the predetermined polishing position. After reaching the predetermined position, the mounting seat 42 is controlled to slide on the mounting seat 1 4 so that the polishing sleeve 44 can polish the side of the wiper motor shaft. The above-mentioned control of the lifting platform 31 and the mounting seat 42 sliding on the guide rail can be driven by a cylinder or a motor. The specific driving method belongs to the existing technology and is not described in detail in the accompanying drawings. A mounting platform 2 5 is fixedly installed on one side of the workbench 11, and a receiving tray 51 is tiltedly installed on the mounting platform 2 5. When the wiper motor shaft is polished, the lifting platform 31 is controlled to slide on the guide rail 3. When the wiper motor shaft is located above the receiving tray 51, the electric chuck 33 is controlled to open and fall into the receiving tray 51. A collection box can be placed at the bottom of the receiving tray 51.

[0026] Example 2:

[0027] Based on the above examples, please refer to Figure 2 、 Figure 3 Figure 4As shown, in order to be able to grind the end of the wiper motor shaft, a guide rail three 6 is fixedly installed at the bottom of the cover plate of the body 1, a U-shaped seat 61 is slidably installed on the guide rail three 6, a third motor 62 is fixedly installed on the U-shaped seat 61, and a grinding wheel 63 is fixedly installed on the end of the output shaft of the third motor 62. A notch is opened in the discharge channel 21 on one side of the grinding wheel 63, and the grinding wheel 63 is used to grind the end face of the motor shaft exposed in the notch. An electric telescopic rod 2 64 is also fixedly installed at the bottom of the cover plate 1, and the end of the output shaft of the electric telescopic rod 2 64 is fixedly connected to one side of the U-shaped seat 61, providing drive for the U-shaped seat 61 to slide on the guide rail 3 6; a water tank 65 is fixedly installed on the top of the body 1, and a water pipe 66 is fixedly installed on one side of the water tank 65. The water pipe 66 passes through the body 1 and is arranged inside the body 1. A plurality of water spray heads 68 are evenly installed at the bottom of the body 1. Since the outer surface of the wiper motor shaft will heat up during the polishing process, if the temperature is too high, the polishing sleeve 44 will wear too quickly. The water spray head 68 can be opened during polishing to cool down, which can effectively extend its service life. A cabinet door 7 is provided on one side of the body 1. Since the interior of the body 1 needs to be cleaned and maintained due to long-term work, the staff can open the cabinet door 7 to perform the above operations on the equipment. The cabinet door 7 is used for cleaning and maintaining the entrance to the interior of the body 1.

[0028] The working principle of the present invention is as follows: when the equipment is working, first, the electric telescopic rod 24 is controlled to extend and retract the baffle 23 in the feeding channel 21, so as to ensure that the wiper motor shaft passes through the feeding channel 21 in an orderly manner, and then the lifting platform 31 is controlled to lift and lower the electric chuck 33 to align the axis of the wiper motor shaft at the bottom of the feeding channel 21, and the lifting platform 31 is controlled to slide so that the electric chuck 33 clamps the wiper motor shaft, and then the electric telescopic rod 24 is controlled to open the baffle 23 below the wiper motor shaft, and then the lifting platform 31 is controlled to slide to the predetermined grinding position. When it reaches the predetermined grinding position, the electric chuck 33 is aligned with the axis of the wiper motor shaft at the bottom of the feeding channel 21. After the wiper motor shaft is positioned, the mounting seat 42 is controlled to slide on the mounting table 4 so that the polishing sleeve 44 can grind the side of the wiper motor shaft. When the polishing of the wiper motor shaft is completed, the lifting platform 31 is controlled to slide on the guide rail 3. When the wiper motor shaft is located above the receiving tray 51, the electric chuck 33 is controlled to open and fall into the receiving tray 51. A collection frame can be placed at the bottom of the receiving tray 51, and then the electric chuck 33 is controlled to re-clamp the wiper motor shaft and repeat the above steps to continue polishing. This equipment can automatically clamp the wiper motor shaft and then polish it, greatly improving the production efficiency.

[0029] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
