Description

Technical Field

[0001] The utility model relates to the technical field related to output shafts, in particular to a grinding device for output shafts. Background Art

[0002] In mechanical design, an output shaft is a shaft that converts mechanical equipment into power output, usually used to drive other equipment or transmission mechanisms. The output shaft is usually directly or indirectly connected to a mechanical power source such as an engine, motor, or reducer to transmit the power.

[0003] The main function of the output shaft is to output the power generated by the mechanical equipment so that it can be used by other equipment or transmission mechanisms. The speed and torque of the output shaft usually need to meet specific requirements to ensure that the output power meets the use requirements. At the same time, in the design of the output shaft, factors such as wear resistance, rigidity, and stability when transmitting power also need to be considered.

[0004] During the production and processing of the output shaft of the one-way clutch, the outer surface of the output shaft will have burrs and burrs to varying degrees. Therefore, it is necessary to perform corresponding processing on the outer surface of the output shaft to reduce the roughness of the outer surface of the output shaft and make the outer surface of the output shaft bright and smooth.

[0005] However, when certain processing errors occur, not only will burrs and burrs appear on the outer surface of the output shaft, but a certain outer diameter error will also occur due to processing errors. When the outer diameter error is small, re-grinding is time-consuming and labor-intensive, and it is not easy to achieve the corresponding accuracy. This type of workpiece is very inconvenient to handle, especially the end processing of the output shaft, which is not easy to locate and contact, and it is easy to over-process during the processing, making the workpiece unusable.

DETAILED DESCRIPTION

[0022] The following is only a preferred embodiment of the present invention, and the protection scope is not limited to this embodiment. All technical solutions under the concept of the present invention should belong to the protection scope of the present invention. At the same time, it should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.

[0023] See Figures 1 to 4 As shown, a grinding device for an output shaft includes a base 11, on which a fixed structure for supporting the output shaft is installed. In this embodiment, the position where the output shaft needs to be processed is mostly the end, and the horizontal axial support and fixation of the output shaft are required to ensure that the output shaft remains stable during the processing.

[0024] The fixing structure includes a slider 31, which is mounted on the base 11. In order to match output shafts of different lengths, the slider 31 is slidably connected to the base 11. The slider 31 can move along the axial direction of the output shaft to ensure that the corresponding output shaft can be easily installed.

[0025] Furthermore, two sliders 31 are provided to facilitate adapting to output shafts of different lengths. Therefore, the two sliders 31 are located on the same horizontal axis.

[0026] like Figure 4 As shown, a retaining ring 32 is fixedly installed on the upper end surface of the slider 31, and the output shaft passes through the retaining ring 32 when installed and used. A plurality of studs 33 are provided on the peripheral wall of the retaining ring 32, and the studs 33 are arranged in an array. In this embodiment, three studs 33 are provided, and the studs 33 are connected to the peripheral surface of the retaining ring 32 along the radial direction of the retaining ring 32. The studs 33 penetrate the peripheral wall of the retaining ring 32 and are threadedly connected to the peripheral wall of the retaining ring 32. After rotating the studs 33, the studs 33 can move toward the axial direction of the retaining ring 32, thereby abutting the output shaft, achieving a supporting and fixing effect, and ensuring that the output shaft can be polished normally.

[0027] In this embodiment, since the lower end of the retaining ring 32 is fixedly connected to the slider 31, the stud 33 cannot be installed at the bottom for support. When the output shaft is just placed in the retaining ring 32, it is easy to be located at the lower side of the center of the retaining ring 32 due to gravity. The studs 33 on both sides are not easy to rotate and support, which affects the fixation. Therefore, a support column 34 is installed at the bottom of the retaining ring 32 for up and down sliding. The support column 34 extends downward and is connected to the slider 31 for up and down sliding. Further, the lower end of the support column 34 can be connected to the slider 31 through a spring. Through the elastic force, the support column 34 can support the output shaft during operation, ensuring that the output shaft is not easy to collapse to the bottom during initial installation, which facilitates the support work of the studs 33 on both sides.

[0028] At the same time, this embodiment also includes a grinding device, which includes a housing 22. The lower end of the housing 22 is fixedly connected to a mounting platform 21. The housing 22 is connected to the base 11 through the mounting platform 21 to ensure the stability of the connection.

[0029] A receiving groove 24 is provided on the side wall of the housing 22, and a grinding column 41 is rotatably mounted on the side wall of the receiving groove 24. The grinding column 41 is used to perform corresponding grinding work on the output shaft. The housing 22 is used to perform corresponding protection work on the grinding column 41 to ensure that the grinding column 41 can work normally.

[0030] The polishing column 41 is connected to a power drive device to control its own rotation for polishing. Therefore, the polishing column 41 is fixedly connected to a drive shaft on the end wall of the accommodating groove 24. The drive shaft and the end wall of the accommodating groove 24 are rotatably connected. At the same time, the drive shaft passes through the accommodating groove 24 and extends out of the housing 22. The drive shaft is connected to a motor 28 on the outside of the housing 22. The motor 28 is fixed on the outer wall of the housing 22 to realize driving work.

[0031] A grinding groove 45 is provided in the grinding column 41, and the grinding groove 45 runs through one side end wall of the grinding column 41. A grinding knife 44 is fixedly installed on the inner wall of the grinding groove 45. When the grinding groove 45 rotates, the output shaft contacts the grinding knife 44, thereby removing burrs and excess dimensions, thereby achieving the grinding of the output shaft.

[0032] The output shaft has different sizes. In the present application, the inner wall of the grinding groove 45 is stepped, and the inner diameter of the grinding groove 45 becomes smaller as it goes inward, so as to adapt to output shafts of different sizes and realize corresponding grinding work. To ensure the normal progress of the grinding work, the opening and the internal steps of the grinding groove 45 are chamfered to prevent damage. The grinding grooves 45 with different steps are all provided with grinding knives 44 to ensure the progress of the grinding work.

[0033] At the same time, a part of the grinding column 41 extends out of the accommodating groove 24, and a gap groove 42 is provided on the side wall of the grinding groove 45. The gap groove 42 is used to throw out waste chips. There are several gap grooves 42, and the gap groove 42 penetrates the side wall of the grinding column 41 and penetrates one side wall of the grinding column 41 axially. The penetration direction is the same as the opening of the grinding groove 45. The grinding groove 45 is a barrel groove, and the output shaft extends into it for grinding. The accumulated waste chips are likely to cause damage to the output shaft during the rotational grinding process. The extended part of the grinding column 41 can completely throw out the waste chips, but the grinding column 41 is completely exposed and easily damaged. Therefore, the housing 22 is required for protection, and only part of the grinding column 41 is extended. When the part of the output shaft to be polished is small, the processing work can be carried out on the part of the grinding column 41 that extends out.

[0034] When the gap groove 42 is not provided, the grinding knife 44 needs to be segmented by itself so that the output shaft is constantly in contact with the blade. After the gap groove 42 is provided, the blade is located at the gap groove 42 and fixed, and waste chips can be easily thrown out.

[0035] like Figure 2 As shown, further, most of the grinding column 41 is located in the receiving groove 24, and the waste chips thrown out from the gap groove 42 are easy to return to the inside of the grinding groove 45 from the gap groove 42. Therefore, a spoiler 43 is provided in the gap groove 42, and the spoiler 43 is fixedly installed in the gap groove 42, and the spoiler 43 is flipped outward to facilitate the discharge of waste chips, and it is not easy to return to the inside of the grinding groove 45. At the same time, the direction of the spoiler 43 is toward the inner side of the receiving groove 24, and the spoiler 43 can also guide the waste chips to be thrown toward the inner side of the receiving groove 24. The housing 22 is in a fixed state, and the waste chips will not continue to move after being thrown out, and can fall and be collected. Throwing them toward the outside of the receiving groove 24 is easy to cause a certain impact on the staff, and it is also easy to contact the unprocessed part of the output shaft and cause damage.

[0036] Furthermore, a waste groove 25 is provided at the bottom of the accommodating groove 24, and the waste groove 25 is used to collect waste chips generated during the grinding process. The waste chips will fall due to gravity after being thrown out of the gap groove 42, but the grinding column 41 will still generate air flow during operation. Therefore, a net bag 27 is connected to the upper side of the waste groove 25, and the net bag 27 is used to collect waste chips. The waste chips are hung on the net bag 27 to prevent further movement. At the same time, waste chips that are too small can fall into the waste groove 25 below the net bag 27. With the net bag blocking them, it is not easy to get out of the waste groove 25 again.

[0037] A fan 26 is provided on the side wall of the waste trough 25, and the fan 26 rotates to draw air inward to collect waste chips.

[0038] The top wall of the receiving groove 25 is provided with an air hole 23 penetrating from top to bottom. The air hole 23 is used to maintain the air pressure balance in the receiving groove 24 to prevent the grinding column 41 from causing the air flow to further drive the waste chips to move when performing the grinding work.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
