Description

Technical Field

[0001] This utility model specifically relates to a cutting and grinding positioning mechanism for shaft-type parts. Background Technology

[0002] Shafts are a common type of hardware component, primarily used to support transmission parts, transmit torque, and bear loads. Miniature shafts are a type of shaft, characterized by their relatively small size and high precision. They are also known as precision shafts, small shafts, shaft cores, rotor shafts, pins, rivets, guide rods, etc. Miniature shafts are used in many industries, such as in motor shafts, printer shafts, copier shafts, and scanner shafts. During the cutting and grinding process, shafts require radial positioning using a cutting and grinding positioning mechanism. However, existing cutting and grinding positioning mechanisms suffer from drawbacks such as complex structural designs, low positioning accuracy, and inconvenient operation. Summary of the Invention

[0003] The purpose of this utility model is to overcome the defects of the prior art and provide a cutting and grinding positioning mechanism for shaft parts that is simple in structure, stable and reliable in performance, convenient in operation, and has high positioning accuracy.

[0004] To achieve the above objectives, this utility model employs a cutting and positioning mechanism for shaft-type parts, comprising a frame, a micrometer mounted on the frame, a slider slidably mounted within the frame and abutting against the micrometer screw, a compression spring positioned between the slider and the frame, and a limiting rod linked to the slider. One end of the limiting rod has a limiting portion that mates with the shaft-type part, abutting against one end of the shaft-type part and forming a limiting fit between the limiting portion and the shaft-type part. The slider has an adjusting hole that mates with the limiting rod, and the other end of the limiting rod passes through the adjusting hole. An adjusting bolt connected to the limiting rod is also provided on the slider.

[0005] The beneficial effects of the above structure are: the limiting rod of the cutting and grinding positioning mechanism plays a radial positioning role for shaft parts, and the micrometer drives the limiting rod to move through the slider, thereby achieving high-precision adjustment of the limiting rod. Furthermore, the pressure of the compression spring ensures that the limiting rod reliably abuts against the shaft parts, guaranteeing the operational reliability of the cutting and grinding positioning mechanism. Therefore, this cutting and grinding positioning mechanism for shaft parts has the advantages of simple structure, stable and reliable performance, convenient operation, and high positioning accuracy.

[0006] Specifically, the mechanism frame is provided with a sliding groove that mates with the slider, and the slider is provided with a guide block that mates with the sliding groove. The guide block is slidably disposed within the sliding groove, forming a sliding connection between the guide block and the mechanism frame. The guide block of the slider is slidably disposed within the sliding groove of the mechanism frame, thereby ensuring reliable movement of the slider on the mechanism frame and facilitating the assembly of the slider and the mechanism frame, making assembly more convenient.

[0007] Specifically, the guide block is provided with a positioning groove, one end of the compression spring abuts against the positioning groove, and the other end of the compression spring abuts against the sliding groove. The compression spring abuts against the positioning groove of the guide block, which facilitates the assembly of the compression spring and the guide block, making assembly more convenient. Moreover, the compression spring can ensure that the guide block can reliably return to its original position, thereby improving the working reliability of the cutting and grinding positioning mechanism.

[0008] Specifically, the sliding groove of the mechanism frame is provided with multiple fixing holes. The fixing holes in the sliding groove facilitate the installation of the cutting and grinding positioning mechanism, making installation more convenient.

[0009] Specifically, the mechanism frame is equipped with a fixing block that mates with the micrometer. The fixing block has a through hole and a slot communicating with the through hole. The micrometer is inserted into the through hole, and a fixing bolt is provided on the fixing block corresponding to the slot. The micrometer is fixed within the fixing block of the mechanism frame, facilitating the assembly of the micrometer with the mechanism frame and improving assembly efficiency.

[0013] like Figures 1-3As shown, this utility model embodiment is a cutting and grinding positioning mechanism for shaft parts, including a frame 10, a micrometer 11 mounted on the frame 10, a slider 12 slidably mounted inside the frame 10 and abutting against the micrometer 11, a compression spring 13 mounted between the slider 12 and the frame 10, and a limiting rod 14 linked to the slider 12. One end of the limiting rod 14 has a limiting part 141 that cooperates with the shaft part 15. The limiting part 141 abuts against one end of the shaft part 15 and forms a limiting cooperation between the limiting part 141 and the shaft part 15. The slider 12 is provided with an adjustment hole 121 that cooperates with the limiting rod 14. The other end of the limiting rod 14 is inserted into the adjustment hole 121, and the slider 12 is provided with an adjustment bolt 16 connected to the limiting rod 121. The mechanism frame 10 is provided with a sliding groove 101 that cooperates with the slider 12. The slider 12 is provided with a guide block 122 that cooperates with the sliding groove 101. The guide block 122 is slidably disposed within the sliding groove 101, forming a sliding connection between the guide block 122 and the mechanism frame 10. The guide block of the slider is slidably disposed within the sliding groove of the mechanism frame, thus ensuring reliable movement of the slider on the mechanism frame and facilitating assembly between the slider and the mechanism frame, making assembly more convenient. The guide block 122 is provided with a positioning groove 1221. One end of the compression spring 13 abuts against the positioning groove 1221, and the other end of the compression spring abuts against the sliding groove 101. The compression spring abuts against the positioning groove of the guide block, thus facilitating assembly between the compression spring and the guide block, making assembly more convenient, and ensuring reliable reset of the guide block, thereby improving the working reliability of the cutting and grinding positioning mechanism.

[0014] like Figure 2 and 3 As shown, the sliding groove 101 of the mechanism frame 10 is provided with multiple fixing holes 102. The fixing holes in the sliding groove facilitate the installation of the cutting and grinding positioning mechanism, making installation more convenient. The mechanism frame 10 is provided with a fixing block 103 that mates with the micrometer 11. The fixing block 103 has a through hole 1031 and a slot 1032 communicating with the through hole 1031. The micrometer 11 is inserted into the through hole 1031, and a fixing bolt 17 is provided on the fixing block 103 corresponding to the slot 1032. The micrometer is fixed in the fixing block of the mechanism frame, facilitating the assembly of the micrometer with the mechanism frame and improving assembly efficiency.

[0015] The limiting rod of this cutting and grinding positioning mechanism provides radial positioning for shaft-type parts. The micrometer drives the limiting rod via a slider, enabling high-precision adjustment of the limiting rod. Furthermore, the pressure of the compression spring ensures that the limiting rod reliably contacts the shaft-type parts, guaranteeing the operational reliability of the cutting and grinding positioning mechanism. Therefore, this cutting and grinding positioning mechanism for shaft-type parts possesses advantages such as simple structure, stable and reliable performance, convenient operation, and high positioning accuracy.
