Description

Technical Field

[0001] This utility model relates to the field of long shaft rotary machining technology, specifically a long shaft rotary machining tooling. Background Technology

[0002] Long-shaft rotary machining fixtures are mainly used for fixing and rotating rotors to ensure that the rotor does not deform or move during machining. These fixtures typically include two bushings that mate with both ends of the rotor. These bushings are respectively fitted onto both ends of the rotor shaft and fixed by shaft head bolts to ensure that the rotor does not deform under stress and to prevent axial movement.

[0003] In conventional long shaft machining, the fixed tooling structure used is relatively complex. In addition, after the workpiece is clamped and limited, there may be problems of off-axis movement and jumping during rotation, which will affect the machining effect and machining quality.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a long-axis rotary machining tool. Utility Model Content

[0005] The purpose of this invention is to provide a long-shaft rotary machining fixture to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a long shaft rotary machining fixture, comprising a fixture table and a clamping table. The clamping table is installed on one side of the top of the fixture table, and the clamping table horizontally clamps the long shaft body on the side near the vertical central axis of the fixture table. A stabilizing platform is provided at the end of the long shaft body away from the clamping platform, and guide blocks are symmetrically installed on the bottom of the stabilizing platform. The clamping table includes a fixed base, a transmission platform, and a three-jaw chuck. The transmission platform is installed on the top of the fixed base, and the three-jaw chuck is installed on the side of the transmission platform near the vertical central axis of the fixture table.

[0007] Furthermore, the tooling table includes a base, a servo motor, a lead screw, and linear guide rails. The servo motor is horizontally mounted on one side of the base, and the power output end of the servo motor is mounted with a lead screw via a coupling. Linear guide rails are provided on both sides of the lead screw.

[0008] Furthermore, the lead screw is horizontally mounted on the top center of the platform, and the linear guide rail is arranged parallel to the lead screw, with the linear guide rail embedded in the top surface of the platform.

[0009] Furthermore, the fixed base is fixedly installed on the top of the platform on the side away from the servo motor, and the transmission table and the three-jaw chuck are both on the same horizontal central axis.

[0010] Furthermore, the stabilizing platform includes a movable platform, a guide sleeve, a bearing seat, and a fixed frame. The guide sleeve is installed in the middle of the bottom of the movable platform, and the bearing seat is installed in the middle of the top of the movable platform. The fixed frame is provided on the top of the bearing seat.

[0011] Furthermore, the guide sleeve is embedded in the middle of the bottom of the moving stage, and the guide sleeve is threadedly connected to the lead screw. The bearing seat is embedded in the middle of the top of the moving stage, and the bearing seat and the three-jaw chuck are on the same horizontal central axis. The surface structure of the fixing frame fits the upper surface of the bearing seat, and the fixing frame is connected to the moving stage by bolts.

[0012] Furthermore, the guide block includes a slider, a limiting groove, and a fixing angle plate. The limiting groove is formed in the middle of the top of the slider, and fixing angle plates are installed on both sides of the limiting groove.

[0013] Furthermore, the slider is slidably connected to the linear guide rail, and the slider is welded to the fixed angle plate. Moreover, the lower side of the moving stage is provided with a groove structure that matches the surface structure of one side of the fixed angle plate, and the limiting groove matches the bottom surface structure of the moving stage.

[0014] This utility model provides a long-shaft rotary machining fixture, which has the following beneficial effects:

[0015] 1. This utility model features a clamping platform installed at the top of one end of a tooling table. A three-jaw chuck is installed on one side of the transmission table. The radial movement of the three movable jaws arranged in a circular array on the chuck body allows for flexible adjustment within a certain range according to the diameter of the long shaft body, enabling clamping and positioning. Combined with a stabilizing platform installed at the other end of the tooling table, the other end of the long shaft body is horizontally inserted into the bearing housing. This, along with the clamping platform structure, ensures sufficient structural stability of the long shaft body during axial rotation, preventing axial wobbling and avoiding unnecessary impact on machining accuracy. Simultaneously, the bearing housing is embedded in the top center of the moving table through a fixed frame structure. This structure also makes the assembly and disassembly of the long shaft body relatively convenient and simple, thus ensuring the structural flexibility and convenience of the tooling.

[0016] 2. This utility model involves inserting the bottom of the moving stage into the limiting groove in the middle of the slider, and then using a fixing angle plate and bolts to connect and fix the stabilizing stage and the guide block together. Since the guide sleeve in the middle of the bottom of the moving stage is connected to the lead screw, and the slider is connected to the linear guide rail, when the servo motor drives the lead screw connected to the linear guide rail to rotate horizontally, it will drive the guide block and the stabilizing stage connected to its top to move horizontally. This allows for adjustment of the relative distance between the clamping stage and the stabilizing stage. Using this structure, on the one hand, the structure can be flexibly disassembled for easy maintenance and cleaning; on the other hand, the flexible structural adjustability allows for flexible adjustment within a certain range according to the length of the main body of the long shaft to meet different usage needs and improve the flexibility of the device.

Detailed Implementation

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] like Figures 1 to 4As shown, a long shaft rotary machining fixture includes a fixture table 1 and a clamping table 2. The clamping table 2 is mounted on one side of the top of the fixture table 1, and the clamping table 2 horizontally clamps the long shaft body 3 on the side of the clamping table 2 closest to the vertical central axis of the fixture table 1. A stabilizing platform 4 is provided at the end of the long shaft body 3 away from the clamping table 2, and guide blocks 5 are symmetrically mounted on the bottom of the stabilizing platform 4. The clamping table 2 includes a fixed base 201, a transmission platform 202, and a three-jaw chuck 203. The transmission platform 202 is mounted on the top of the fixed base 201. A three-jaw chuck 203 is installed on the side of the transmission table 202 near the vertical central axis of the tooling table 1. The fixed base 201 is fixedly installed on the top of the base 101 on the side away from the servo motor 102. The transmission table 202 and the three-jaw chuck 203 are both on the same horizontal central axis. The stabilizing table 4 includes a moving table 401, a guide sleeve 402, a bearing seat 403, and a fixed frame 404. The guide sleeve 402 is installed in the middle of the bottom of the moving table 401, and the bearing seat is installed in the middle of the top of the moving table 401. 403, and the top of the bearing housing 403 is provided with a fixing frame 404. The guide sleeve 402 is embedded in the middle of the bottom of the moving table 401, and the guide sleeve 402 is threadedly connected to the lead screw 103. The bearing housing 403 is embedded in the middle of the top of the moving table 401, and the bearing housing 403 and the three-jaw chuck 203 are on the same horizontal central axis. The surface structure of the fixing frame 404 fits the upper surface of the bearing housing 403, and the fixing frame 404 is connected to the moving table 401 by bolts. By using the radial movement of the three movable jaws distributed in a ring array on the chuck body, the diameter of the long shaft body 3 can be flexibly adjusted within a certain range, and it can be clamped and positioned. With the help of the stabilizing platform 4 installed at the other end of the tooling table 1, by horizontally inserting the other end of the long shaft body 3 into the inside of the bearing housing 403, and with the help of the clamping platform 2, sufficient structural stability of the long shaft body 3 can be ensured during axial rotation.

[0024] like Figures 1 to 4As shown, the tooling table 1 includes a base 101, a servo motor 102, a lead screw 103, and a linear guide rail 104. The servo motor 102 is horizontally mounted on one side of the base 101, and the lead screw 103 is mounted on the power output end of the servo motor 102 via a coupling. Linear guide rails 104 are provided on both sides of the lead screw 103. The lead screw 103 is horizontally mounted at the top center of the base 101, and the linear guide rails 104 are parallel to the lead screw 103. The linear guide rails 104 are embedded in the top surface of the base 101. The guide block 5 includes a slider 501, a limiting groove 502, and a fixing angle plate 503. The top center of the slider 501 is open... A limiting groove 502 is provided, and fixed angle plates 503 are installed on both sides of the limiting groove 502. The slider 501 is slidably connected to the linear guide rail 104, and the slider 501 is welded to the fixed angle plate 503. The lower side of the moving stage 401 has a groove structure that matches the surface structure of one side of the fixed angle plate 503. The limiting groove 502 and the bottom surface structure of the moving stage 401 are matched with each other. When the servo motor 102 drives the lead screw 103 connected to it to rotate horizontally, it will drive the guide block 5 to move horizontally through the stable platform 4 connected to its top, thereby realizing the adjustment of the relative distance between the clamping stage 2 and the stable platform 4.

[0025] In summary, as Figures 1 to 4 As shown, when using this long shaft rotary machining fixture, firstly, according to the length of the long shaft body 3, the servo motor 102 on one side of the table 101 is started. Driven by the servo motor 102, the lead screw 103 connected to its power output end is rotated horizontally, thereby driving the stable table 4 connected to the lead screw 103 through the guide sleeve 402 to move horizontally. At the same time, the slider 501, which is fixed to the stable table 4 with the fixed angle plate 503, moves horizontally along the surface of the linear guide rail 104. Thus, under the operation of the fixture table 1, the relative distance between the stable table 4 and the clamping table 2 is adjusted with the help of the guide block 5.

[0026] After adjustment, insert one end of the long shaft body 3 into the middle of the bearing seat 403, and embed the bearing seat 403 into the top middle of the platform 101. Then, use the fixing bracket 404 and bolts to fix it to the top of the platform 101. Next, insert the other end of the long shaft body 3 into the axis of the three-jaw chuck 203. Then, adjust the three-jaw chuck 203 to clamp and fix the other end of the long shaft body 3, so that the clamping platform 2, the long shaft body 3, and the stabilizing platform 4 are on the same horizontal central axis. Finally, connect the power output end of the external drive motor to the other side of the transmission platform 202, so as to drive the three-jaw chuck 203 and the long shaft body 3 to rotate horizontally for rotary machining.
