Nut machining stable clamping device

Abstract

This utility model discloses a stable clamping device for nut processing, specifically relating to the field of nut processing technology. It includes a moving disc, which is precisely fixed by a limiting seat and a limiting groove in the assembly window under the action of a coil spring. The rotating disc can rotate freely. When the servo motor is activated, the drive roller drives the rotating disc to rotate. The moving roller within the arc-shaped groove is constrained by its trajectory, causing the clamping plate to move radially. When it approaches the nut, the buffer pad contacts and securely clamps the nut. As the drive roller continues to rotate, when the driving force overcomes the spring force, the limiting seat disengages, and the moving disc and rotating disc rotate synchronously. This allows for drilling, grinding, etc., of the nut according to processing requirements. Operation is simple; only the servo motor needs to be activated to complete clamping and rotation sequentially, reducing labor intensity and operational difficulty. It is highly versatile; the movement roller and groove cooperation allow the clamping plate to adapt to various nut specifications, saving on fixture replacement costs. It is low-cost, and the integrated design reduces auxiliary equipment.

Description

Technical Field

[0001] This utility model relates to the field of nut processing technology, specifically a stable clamping device for nut processing. Background Technology

[0002] Nut machining often requires fixing before rotation. When machining a nut blank on a lathe, the blank must first be fixed on the lathe fixture, such as a three-jaw chuck or a four-jaw chuck, to keep it in a stable position. Then, the lathe is started, and the blank rotates with the chuck. The cutting tool then cuts the rotating blank to obtain the preliminary shape of the nut, including the machining of dimensions such as the outer diameter and end face.

[0003] Traditional devices typically require multiple components to perform both fixing and rotation functions. For example, a separate clamp is used for fixing, and then a motor and transmission mechanism are used to achieve rotation, resulting in a complex overall structure. Furthermore, due to the involvement of multiple components and operating steps, operators need to operate and adjust the fixing and rotating mechanisms separately, increasing the complexity and difficulty of operation and reducing work efficiency. Therefore, we propose a stable clamping device for nut processing to solve the above problems. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A nut processing stabilizing clamping device includes a worktable, a control component on the top of the worktable, an assembly window extending through the surface of the worktable, and multiple evenly distributed limiting grooves on the inner wall of the assembly window. The control component includes a servo motor, a drive roller fixedly connected to the output end of the servo motor, a rotating disk fixedly connected to the top of the drive roller, a moving disk on the top of the rotating disk, multiple evenly distributed arc-shaped grooves on the surface of the rotating disk, multiple radial grooves matching the positions of the arc-shaped grooves on the surface of the moving disk, a moving roller housed within the arc-shaped grooves, a clamping plate fixedly connected to the top of the moving roller, multiple evenly distributed mounting grooves around the moving disk, a fixed cylinder fixedly connected to one side of the inner wall of the mounting groove, a rotating roller housed within the fixed cylinder, a coil spring sleeved on the top of the rotating roller and placed inside the fixed cylinder, and a limiting seat sleeved on the surface of the rotating roller, the limiting seat being slidably connected to the wall of the limiting groove.

[0007] Preferably, the servo motor is located at the bottom of the worktable.

[0008] Preferably, the rotating disk is placed inside the assembly window and is rotatably connected to the inner wall of the assembly window.

[0009] Preferably, the top of the rotating disk has a rotating groove, and multiple balls are installed around the perimeter of the moving disk. The side of the balls away from the moving disk contacts the wall of the rotating groove.

[0010] Preferably, the bottom of the motion roller is fitted with a sliding seat for stabilizing itself, and one end of the top of the motion roller extends through a radial groove to the top of the motion disk.

[0011] Preferably, a buffer pad is fixedly connected to the surface of the clamping plate.

[0012] Preferably, one end of the rotating roller is rotatably connected to the wall of the mounting groove, one end of the coil spring is fixedly connected to the inner wall of the fixed cylinder, and the other end of the coil spring is fixedly connected to the rotating roller.

[0013] Preferably, the end of the limiting seat away from the rotating roller is provided with an elliptical head that facilitates its passage through the limiting groove, and the two sides of the mounting groove are provided with embedding grooves that facilitate the entry of the limiting seat.

[0014] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0015] In this invention, the moving disc is precisely fixed by a tight fit between the limiting seat and the limiting groove of the assembly window under the action of a coil spring, while the rotating disc can rotate freely. When the servo motor is activated, the drive roller drives the rotating disc to rotate. The moving roller within the arc-shaped groove is constrained by its trajectory, causing the clamping plate to move radially. When it approaches the nut, the buffer pad contacts and securely clamps the nut. As the drive roller continues to rotate, when the driving force overcomes the spring force, the limiting seat disengages, and the moving disc and rotating disc rotate synchronously. This allows for drilling, grinding, etc., of the nut according to processing requirements. Operation is simple; only the servo motor needs to be activated to sequentially complete clamping and rotation, reducing labor intensity and operational difficulty. It is highly versatile; the movement roller and groove cooperation allow the clamping plate to adapt to various nut specifications, saving on fixture replacement costs. The integrated design reduces auxiliary equipment, resulting in a compact structure with fewer parts and easy operation and maintenance. Overall, it offers a high-performance, cost-effective option for nut processing. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Figures 1-5As shown, this utility model provides a stable clamping device for nut processing, including a worktable 1. A control component 2 is provided on the top of the worktable 1. An assembly window 101 extends through the surface of the worktable 1. Multiple evenly distributed limiting grooves 102 are formed on the inner wall of the assembly window 101. The control component 2 includes a servo motor 201, which is located at the bottom of the worktable 1. A drive roller 202 is fixedly connected to the output end of the servo motor 201. A rotating disk 203 is fixedly connected to the top of the drive roller 202. The rotating disk 203 is placed inside the assembly window 101 and rotatably connected to the inner wall of the assembly window 101. A moving disk 204 is provided on the top of the rotating disk 203. A rotating groove 205 is formed on the top of the rotating disk 203. Multiple ball bearings 206 are installed around the moving disk 204. The ball bearing 206, located away from the moving disk 204, contacts the wall of the rotating groove 205. The surface of the rotating disk 203 has multiple evenly distributed arc-shaped grooves 207. The surface of the moving disk 204 has multiple radial grooves 208 whose positions match the arc-shaped grooves 207. A moving roller 209 is housed within each arc-shaped groove 207. A sliding seat 210 for stabilizing itself is fitted onto the bottom of the moving roller 209. One end of the moving roller 209 extends through the radial grooves 208 to the top of the moving disk 204. A clamping plate 211 is fixedly connected to the top of the moving roller 209, and a buffer pad 212 is fixedly connected to the surface of the clamping plate 211. When the servo motor 201 is started, its output drives the drive roller 202 to rotate, which in turn drives the rotating disk 203 to rotate within the assembly window 101. Because the moving disk 204 is fixed by the limiting seat 217, the rotation of the rotating disk 203 does not cause the moving disk 204 to rotate synchronously. When the rotating disk 203 rotates, the motion roller 209 within the arc-shaped groove 207 on its surface is constrained by the trajectory of the arc-shaped groove 207. The sliding seat 210 fitted at the bottom ensures motion stability. One end of the top of the motion roller 209 passes through the radial groove 208 of the motion disk 204 that matches the arc-shaped groove 207, driving the clamping plate 211 to move radially closer to or away from the nut. When the clamping plate 211 approaches the nut to a suitable position, the buffer pad 212 contacts the nut first. The buffer pad 212 can both protect the surface of the nut from damage and increase friction, allowing the clamping plate 211 to firmly fix the nut. At this time, because the clamping plate 211 is in close contact with the nut, the clamping plate 211 cannot move.

[0024] Furthermore, multiple evenly distributed mounting slots 213 are provided around the motion disk 204. A fixed cylinder 214 is fixedly connected to one side of the inner wall of the mounting slot 213. A rotating roller 215 is built into the fixed cylinder 214. One end of the rotating roller 215 is rotatably connected to the wall of the mounting slot 213. A coil spring 216 is sleeved on the top of the rotating roller 215. The coil spring 216 is placed inside the fixed cylinder 214. One end of the coil spring 216 is fixedly connected to the inner wall of the fixed cylinder 214, and the other end of the coil spring 216 is fixedly connected to the rotating roller 215. A limiting seat 217 is sleeved on the surface of the rotating roller 215. The limiting seat 217 is slidably connected to the wall of the limiting groove 102. An elliptical head 218 is provided at the end of the limiting seat 217 away from the rotating roller 215 to facilitate its passage through the limiting groove 102. Embedding slots 219 are provided on both sides of the mounting slot 213 to facilitate the entry of the limiting seat 217. The servo motor 201 is located at the bottom of the worktable 1 as a power source. Before startup, the rotating rollers 215 in the mounting grooves 213 around the moving disk 204, under the elastic force of the coil springs 216, cause the limiting seat 217 to be tightly inserted into the limiting groove 102 on the inner wall of the assembly window 101, firmly fixing the moving disk 204 in its initial position. At this time, the rotating disk 203 can rotate freely, the moving disk 204 is stationary, and the drive rollers 202 continue to rotate. After the fixing is completed, the rotating disk 203 continues to rotate. When the driving force transmitted by the rotating disk 203 overcomes the elastic force of the coil springs 216, the limiting seat 217 begins to disengage from the limiting groove 102, and the moving disk 204 rotates synchronously with the rotating disk 203. Afterward, the device holding the nut can rotate according to the processing requirements to realize subsequent processing of the nut, such as drilling, grinding, and other processes.

[0025] The device integrates the fixing and rotation functions of the nut into one unit. By simply starting the servo motor 201, the clamping and rotation processing actions can be completed sequentially. Operators do not need complicated operations, reducing labor intensity and operating difficulty, and it is easy to learn. In the initial stage, the limit seat 217 and the limit groove 102 cooperate to precisely fix the moving plate 204, ensuring the accurate starting position of the clamping plate 211, which can achieve high-precision clamping of the nut and effectively ensure the positional accuracy of the nut during processing, meeting the requirements of precision machining. With the flexible cooperation of the moving roller 209 in the arc groove 207 and radial groove 208, the clamping plate 211 can adjust the radial position according to different nut sizes, adapting to the processing of nuts of various specifications, improving the versatility of the device, reducing the cost and time of fixture replacement required due to changes in nut specifications. The integrated design of the device reduces the need for additional auxiliary equipment, has a compact structure, and fewer parts than conventional complex fixtures, reducing manufacturing costs. Moreover, it is easy to operate and has low maintenance costs, effectively controlling the overall cost.

[0026] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
