The lathe surface is provided with a bracket, and the inner side of the bracket is provided with a clamping mechanism. The textile drive shaft body is engaged inside the clamping mechanism. A set of auxiliary mechanisms are symmetrically arranged on the surface of the clamping mechanism. Each auxiliary mechanism includes a cylindrical frame, with one set of cylindrical frames symmetrically fixed to the surface of the clamping mechanism. A U-shaped locking rod passes through the inside of the cylindrical frame. A set of limiting ring plates is symmetrically fixedly sleeved on the surface of the U-shaped locking rod. This utility model effectively drives the end of the U-shaped locking rod to detach from the clamp by pulling it outwards. At this time, the clamp is unrestricted and can be moved forward or backward directly to remove it from the limiting frame, improving disassembly efficiency. When installing the required clamp, the clamp is inserted into the limiting frame while pulling the U-shaped locking rod outwards. Then, the U-shaped locking rod is released. Due to the spring's rebound force, the end of the U-shaped locking rod pops out and effectively engages in the inner groove of the clamp, achieving rapid limiting of the clamp.

Technical Field

[0001] This utility model relates to the field of transmission shaft processing technology, and in particular to a fixture for turning textile transmission shafts. Background Technology

[0002] Transmission shaft machining refers to a series of mechanical operations performed on a transmission shaft to achieve the required dimensions, shape, precision, and surface quality, thereby fulfilling its function of transmitting power and motion in various mechanical equipment. During the cutting process, a fixture is required to limit the movement of the shaft tube.

[0003] Patent number CN212071197U provides a turning positioning fixture for automotive drive shafts, suitable for production and application in the field of automotive drive shaft machining technology. The turning positioning fixture for automotive drive shafts includes a support base, a cylinder, a bottom clamping plate, a top clamping plate, and a guide slide. The cylinder is mounted on the top of the support base, and a push shaft is arranged above the cylinder, with its bottom end threadedly connected to the power output end of the cylinder. A clamping sleeve is glued to the upper end of the outer wall of the push shaft. The beneficial effects of this invention are: by setting up a bottom clamping plate, a top clamping plate, a guide slide, a first movable shaft, a second movable shaft, a shaft tube, a threaded cap, and a threaded rod, it not only facilitates the user in clamping different objects, but also has good applicability; at the same time, while facilitating manual clamping, its manual clamping stability is good, and its practicality is excellent, solving the problems of limited applicability and poor practicality of existing turning positioning fixtures for automotive drive shafts.

[0004] However, the aforementioned machining positioning fixture for automotive drive shafts still has the following shortcomings:

[0005] In the above-mentioned device, several positioning clamping rings are fixed to the surface of the top clamping plate and the bottom clamping plate by several screws. The subsequent replacement of the positioning clamping rings is time-consuming and labor-intensive, thus affecting the processing efficiency. In view of this, we propose a fixture for turning textile transmission shafts. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a fixture for turning textile drive shafts. This solves the technical problem that in the current device, several positioning clamping rings are fixed to the surface of the top clamping plate and the bottom clamping plate by several screws, which makes the subsequent replacement of the positioning clamping rings time-consuming and labor-intensive, thus affecting the processing efficiency.

[0007] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a fixture for turning textile transmission shafts is designed and applied to a lathe. A bracket is provided on the surface of the lathe, and a clamping mechanism is provided inside the bracket. The textile transmission shaft body is engaged inside the clamping mechanism, and a set of auxiliary mechanisms are symmetrically arranged on the surface of the clamping mechanism.

[0008] The auxiliary mechanism includes a cylindrical frame, a set of cylindrical frames symmetrically fixed to the surface of the clamping mechanism, a U-shaped clamping rod penetrating inside the set of cylindrical frames, a set of limiting ring plates symmetrically fixed on the surface of the U-shaped clamping rod, and a spring provided on one side of the limiting ring plate.

[0009] Preferably, the U-shaped lever is formed into an elastic structure by a limiting ring plate, a spring, and a cylindrical frame, with the outer wall of the limiting ring plate fitting against the inner wall of the cylindrical frame.

[0010] Preferably, the clamping mechanism includes positive and negative lead screws, which are movably mounted on the right side of the bracket. A motor is connected to the top of the positive and negative lead screws, and a positioning frame is provided on the outside of the motor. A guide slide rod is fixed on the left side of the bracket. A set of limiting frames are symmetrically sleeved on the surface of the positive and negative lead screws, and a set of clamping frames are symmetrically engaged on the inner side of the middle of the set of limiting frames.

[0011] Preferably, the inner side of the right end of the limiting frame is provided with a threaded hole for engaging with the threads on the surface of the positive and negative lead screws, and the inner side of the left end of the limiting frame is provided with a through hole for sliding engagement with the guide slide rod.

[0012] Preferably, the clamp is composed of a T-shaped rod and an arc-shaped plate, and the outer wall of the textile drive shaft body is closely fitted with the arc-shaped inner wall of a set of clamps.

[0013] Preferably, the clamp is movably engaged with the inner side of the middle of the limiting frame, and the surface of the clamp is provided with a groove that matches the end of the U-shaped clamp rod. When the spring is in the critical state of compression, the end of the U-shaped clamp rod just disengages from the clamp.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model effectively drives the end of the U-shaped clamp to detach from the clamp by pulling outward. At this time, the clamp is unrestricted and can be moved forward or backward directly to remove it from the limiting frame, improving disassembly efficiency. When installing the required clamp, the clamp is inserted into the limiting frame based on pulling outward on the U-shaped clamp. Then, the U-shaped clamp is released. Under the influence of the spring rebound force, the end of the U-shaped clamp pops out and effectively engages in the inner groove of the clamp, realizing the rapid limiting of the clamp.

[0016] 2. This utility model effectively drives the positive and negative lead screws to rotate clockwise using a motor, thereby causing a set of limiting frames and a set of clamps fitted on the surfaces of the positive and negative lead screws to move away from each other, providing a placement space for the textile drive shaft body to be clamped. Then, the textile drive shaft body to be clamped is placed inside the lower clamp. At the same time, the positive and negative lead screws are effectively driven to rotate counterclockwise using a motor, thereby causing the set of limiting frames and a set of clamps fitted on the surfaces of the positive and negative lead screws to move closer to each other until the arc-shaped inner wall of the clamp is in close contact with the surface of the textile drive shaft body, thus completing the clamping and limiting of the textile drive shaft body. The guide slide is used to improve the vertical movement stability of the limiting frames. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0025] A fixture for turning textile drive shafts, see [link / reference] Figures 1 to 4 It is applied to a lathe 1. The lathe 1 has a support 2 on its surface. The support 2 has a clamping mechanism 3 on its inner side. The clamping mechanism 3 has a textile transmission shaft body 4 inside it. A set of auxiliary mechanisms 5 are symmetrically arranged on the upper and lower surfaces of the clamping mechanism 3.

[0026] The auxiliary mechanism 5 includes a cylindrical frame 501. A set of cylindrical frames 501 are symmetrically fixed to the surface of the clamping mechanism 3. A U-shaped locking rod 502 passes through the inside of the set of cylindrical frames 501. A set of limiting ring plates 503 are symmetrically fixed on the surface of the U-shaped locking rod 502. A spring 504 is provided on one side of the limiting ring plate 503. The U-shaped locking rod 502 forms an elastic structure with the cylindrical frame 501 through the limiting ring plate 503 and the spring 504. The outer wall of the limiting ring plate 503 is in contact with the inner wall of the cylindrical frame 501. This utility model effectively drives the end of the U-shaped clamp 502 to disengage from the clamp 306 by pulling the U-shaped clamp 502 outward. At this time, the clamp 306 is unrestricted and can be moved forward or backward directly to be pulled away from the limiting frame 305, improving disassembly efficiency. When installing the required clamp 306, the clamp 306 is inserted into the limiting frame 305 based on pulling the U-shaped clamp 502 outward. Then, the U-shaped clamp 502 is released. Under the influence of the spring 504's rebound force, the end of the U-shaped clamp 502 pops out and effectively engages in the inner groove of the clamp 306, realizing the rapid limiting of the clamp 306.

[0027] It is worth noting that the clamping mechanism 3 includes a positive and negative lead screw 301, which is movably mounted on the right side of the bracket 2. A motor 302 is connected to the top of the positive and negative lead screw 301, and a positioning bracket 303 is provided on the outside of the motor 302. A guide slide rod 304 is fixed on the left side of the bracket 2. A set of limiting brackets 305 are symmetrically fitted on the surface of the positive and negative lead screw 301. The inner side of the right end of the limiting bracket 305 has a threaded hole for engaging with the thread on the surface of the positive and negative lead screw 301, and the inner side of the left end of the limiting bracket 305 has a through hole for engaging with the guide slide rod. The rod 304 is slidably engaged, and a set of clamps 306 are symmetrically engaged on the inner side of the middle of a set of limiting frames 305. Furthermore, the clamps 306 are composed of a T-shaped rod and an arc-shaped plate. The outer wall of the textile drive shaft body 4 is tightly fitted with the arc-shaped inner wall of the set of clamps 306. Furthermore, the clamps 306 are movably engaged on the inner side of the middle of the limiting frame 305. The surface of the clamps 306 is provided with a groove that matches the end of the U-shaped clamp 502. When the spring 504 is in the critical state of compression, the end of the U-shaped clamp 502 just disengages from the clamps 306. This invention effectively drives the positive and negative lead screws 301 to rotate clockwise via the motor 302, thereby causing a set of limiting frames 305 and a set of clamps 306 fitted on the surface of the positive and negative lead screws 301 to move away from each other, providing a space for the textile transmission shaft body 4 to be clamped. Then, the textile transmission shaft body 4 to be clamped is placed inside the lower clamp 306. At the same time, the motor 302 effectively drives the positive and negative lead screws 301 to rotate counterclockwise, thereby causing the set of limiting frames 305 and a set of clamps 306 fitted on the surface of the positive and negative lead screws 301 to move closer to each other until the arc-shaped inner wall of the clamp 306 is in close contact with the surface of the textile transmission shaft body 4, thus completing the clamping and limiting of the textile transmission shaft body 4. The guide slide rod 304 is used to improve the vertical movement stability of the limiting frames 305.

[0028] Working principle: By pulling outwards, the U-shaped clamp 502 causes its end to disengage from the clamp 306. At this time, the original clamp 306 is unrestricted and can be moved forward or backward directly to remove it from the limiting frame 305. When installing the required clamp 306, the clamp 306 is inserted into the limiting frame 305 while the U-shaped clamp 502 is pulled outwards. Then, the U-shaped clamp 502 is released. Due to the rebound force of the spring 504, the end of the U-shaped clamp 502 pops out and engages in the inner slot of the required clamp 306, realizing the rapid limiting of the clamp 306. Then, the motor 302 drives the forward and reverse lead screws 301 to move forward and backwards. The clockwise rotation causes a set of limiting frames 305 and a set of clamps 306 fitted on the surface of the positive and negative lead screws 301 to move away from each other, providing space for the textile drive shaft body 4 to be clamped. Then, the textile drive shaft body 4 to be clamped is placed inside the lower clamp 306. At the same time, the motor 302 drives the positive and negative lead screws 301 to rotate counterclockwise, causing the set of limiting frames 305 and a set of clamps 306 fitted on the surface of the positive and negative lead screws 301 to move closer to each other until the arc-shaped inner wall of the clamp 306 is in close contact with the surface of the textile drive shaft body 4, thus completing the clamping and limiting of the textile drive shaft body 4.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations.
