Description

Technical Field

[0001] This utility model relates to the field of lathe parts machining fixtures, specifically a lathe universal joint shaft section machining fixture. Background Technology

[0002] The universal joint of a lathe is a key transmission component that connects the power source and the actuator of a lathe. Its core function is to stably transmit torque and rotational motion when there is an angular deviation between the two axes, ensuring that the lathe can maintain machining accuracy under complex working conditions. From ordinary horizontal lathes to precision CNC lathes, the universal joint is the "joint" that realizes flexible power transmission. Its performance directly affects the speed stability, torque output and machining quality of the lathe.

[0003] However, existing technologies still have many defects in some similar structures when used in practice. For example, if the machining fixture cannot adjust the position of the universal joint shaft section, for shaft sections that require multiple processing steps, the inability to adjust the position requires frequent disassembly and re-clamping, increasing operation time and labor intensity, reducing processing efficiency. At the same time, the shaft section is prone to shaking and displacement during processing, resulting in deviations in the processing position. It is inconvenient to clamp and fix the universal joint shaft section, which may cause abnormal collisions with the machining tool, damaging the tool and shaft section, and even causing equipment failure.

[0004] To address the aforementioned problems, the inventors proposed a lathe universal joint shaft segment machining fixture to solve these issues. Utility Model Content

[0005] To address the problems of inconvenience in adjusting the position of the universal joint shaft segment and inconvenience in clamping and fixing the universal joint shaft segment, the purpose of this utility model is to provide a machining fixture for the universal joint shaft segment of a lathe.

[0006] To solve the above technical problems, this utility model adopts the following technical solution: a lathe universal joint shaft segment machining fixture, including a table, a sliding assembly fixedly connected to one side of the top surface of the table, the sliding assembly including a base, the bottom end of the base being fixedly connected to the top end of the table, the top end of the base having multiple first sliding grooves distributed at equal intervals, the inner walls of the two sides of the middle first sliding groove being rotatably connected to a lead screw, the top end of the table being fixedly connected to a first motor, the output end of the first motor passing through one end of the table and fixedly connected to one end of the lead screw, the two sides of the first sliding grooves being connected to the lead screw. All the inner walls of the sides are fixedly connected to a fixing rod. The inner walls of the multiple first sliding grooves are slidably connected to a first slider. The outer surface of the lead screw is threadedly sleeved with the inner wall of the middle first slider. The outer surfaces of the multiple fixing rods are respectively movably sleeved with the inner walls of the two side first sliders. The tops of the multiple first sliders are fixedly connected to a slide plate. The tops of the slide plate are fixedly connected to two sides of the slide plate. The two ends of the slide plate are fixedly connected to a second slider. The opposite sides of the multiple fixing plates are provided with a second sliding groove for use with the second slider. The top surface of the slide plate is fixedly connected to a clamping assembly.

[0007] As a preferred technical solution of this application, the clamping assembly includes a support plate, a connecting plate symmetrically fixedly connected to the top surface of the support plate, a bidirectional threaded rod rotatably connected to one end of the opposite surface of the connecting plate, a second motor fixedly connected to one side of one of the connecting plates, the output end of the second motor extending into the connecting plate and fixedly connected to the bidirectional threaded rod, two connecting blocks threadedly sleeved on the outer surface of the bidirectional threaded rod, an electric telescopic joint fixedly connected to one side of the connecting block, and a clamping frame fixedly connected to the end of the electric telescopic joint.

[0008] With the above technical solution, after the second motor starts, the output end drives the bidirectional threaded rod to rotate between the two connecting plates. Since the two connecting blocks are respectively threaded on the outer surface of the bidirectional threaded rod at different thread directions, and the connecting blocks are movably connected with the limit rod, the connecting blocks will move relative to each other along the bidirectional threaded rod. The electric telescopic joint extends and retracts to adjust the position of the clamping frame, so that the two clamping frames fit against the outer surface of the shaft section, which can effectively clamp and fix the universal shaft section.

[0009] As a preferred technical solution of this application, a plurality of placement platforms are fixedly connected to one side of the top surface of the table.

[0010] The above technical solution allows the placement platform to be used for temporary placement of shaft segments to be processed or processed, facilitating easy access.

[0011] As a preferred technical solution of this application, the outer surface of the second slider is in contact with the inner wall of the second slide groove, and both the second slider and the second slide groove are "T" shaped.

[0012] Using the above technical solution, the second slider slides within the inner wall of the second groove.

[0013] As a preferred technical solution of this application, a limiting rod is fixedly connected to one end of the opposite side of the connecting plate, and the outer surface of the limiting rod is movably sleeved with the connecting block.

[0014] The above technical solution limits the movement of the connecting block using the limiting rod.

[0015] As a preferred technical solution of this application, the plurality of clamping frames are respectively threaded onto the outer surface of the bidirectional threaded rod at different thread directions.

[0016] Using the above technical solution, the connecting block will move relative to the bidirectional threaded rod.

[0017] As a preferred technical solution of this application, the outer surfaces of the plurality of clamping frames are all arc-shaped.

[0018] Through the above technical solution, the two clamping frames fit the outer surface of the shaft section.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. This utility model allows the lead screw to rotate in the first slide groove in the middle. Since the lead screw is threadedly connected to the first slider in the middle, and the first sliders on both sides are movably connected to the fixed rod, the first slider will slide along the first slide groove, thereby driving the top slide plate to move synchronously. When the slide plate moves, the second sliders at both ends slide along the second slide groove on the fixed plate to ensure that the slide plate moves smoothly, thereby achieving the purpose of adjusting the position of the universal joint shaft section.

[0021] 2. This utility model can rotate between two connecting plates via a bidirectional threaded rod, with the connecting block and the limiting rod movably connected. The connecting block will move relative to the bidirectional threaded rod, and the electric telescopic joint will extend and retract to adjust the position of the clamping frame, so that the two clamping frames fit against the outer surface of the shaft section, thereby achieving the purpose of effectively clamping and fixing the universal shaft section.

[0030] The output end of the first motor 205 passes through one end of the table 1 and is fixedly connected to one end of the lead screw 203. The inner walls of both sides of the first slide groove 202 are fixedly connected to the fixing rod 204. The inner walls of the multiple first slide grooves 202 are slidably connected to the first slider 206. The outer surface of the lead screw 203 is threadedly sleeved with the inner wall of the middle first slider 206. The outer surfaces of the multiple fixing rods 204 are respectively movably sleeved with the inner walls of the two sides of the first slider 206. The tops of the multiple first sliders 206 are fixedly connected to the slide plate 207. The tops of the slide plate 207 are fixedly connected to the fixing plates 208 on both sides. The two ends of the slide plate 207 are fixedly connected to the second slider 209. The opposite side of the multiple fixing plates 208 is provided with a second slide groove 210 for use with the second slider 209. The outer surface of the second slider 209 fits against the inner wall of the second slide groove 210. The second slider 209 and the second slide groove 210 are both "T" shaped. The top surface of the slide plate 207 is fixedly connected to the clamping assembly 3.

[0031] When the slide plate 207 moves, the second sliders 209 at both ends slide along the second slide grooves 210 on the fixed plate 208 to ensure that the slide plate 207 moves smoothly.

[0032] The clamping assembly 3 includes a support plate 31. A connecting plate 32 is symmetrically and fixedly connected to the top surface of the support plate 31. A bidirectional threaded rod 33 is rotatably connected to one end of the opposite surface of the connecting plate 32. A second motor 34 is fixedly connected to one side of one of the connecting plates 32. The output end of the second motor 34 extends into the connecting plate 32 and is fixedly connected to the bidirectional threaded rod 33. Two connecting blocks 35 are threadedly sleeved on the outer surface of the bidirectional threaded rod 33.

Since the two connecting blocks 35 are respectively threaded on the outer surface of the bidirectional threaded rod 33 at different thread directions, and the connecting blocks 35 are movably connected to the limiting rod 36, the connecting blocks 35 will move relative to the bidirectional threaded rod 33. The electric telescopic joint 37 extends and retracts to adjust the position of the clamping frame 38, so that the two clamping frames 38 fit against the outer surface of the shaft segment, thereby achieving the purpose of effectively clamping and fixing the universal shaft segment.
