Description

Technical Field

[0001] This utility model relates to the field of workpiece clamping fixture technology, specifically an automatic clamping rotary spindle. Background Technology

[0002] Against the backdrop of rapid technological development and continuous industrial upgrading, and with the steady and continuous improvement of industrial automation, the manufacturing industry, a vital sector concerning the national economy and comprehensive strength, has placed more stringent and higher demands on the automation level of processing equipment. Automatic clamping rotary spindle technology has emerged to meet this need. It can automatically clamp and rotate parts without manual intervention, thereby greatly improving processing efficiency and precision.

[0003] When the automatic clamping rotary spindle clamps and fixes the workpiece, the clamping blocks on the clamping assembly squeeze and clamp the outer wall of the workpiece, making it less likely for the workpiece to slip during processing. However, when the outer wall of the workpiece is clamped by a single clamping block, the workpiece is prone to slipping and moving due to the smoothness of the outer wall, which affects the accuracy and quality of processing. Utility Model Content

[0004] The purpose of this invention is to provide an automatic clamping rotary spindle to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

A fixing plate is fixedly installed on the side of the arc-shaped plate, and an adjustment strip is provided on one side of the fixing plate. The fixing mechanism is used to strengthen the clamping and fixing of the workpiece.

[0008] A limiting mechanism is provided on one side of the clamping assembly. The limiting mechanism includes a rotating plate located on one side of the clamping assembly.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention pushes an arc-shaped plate and moves the fixed box into a slide groove. Under the pressure of the slide groove, the locking block drives the moving plate to move and presses against the elastic element. When the locking block moves to the slot, the elastic force of the elastic element pushes the moving plate and the locking block to move. The locking block engages with the slot, thereby fixing the fixed box and the arc-shaped plate, and further fixing the fixed plate. The bottom surface of the fixed plate is provided with multiple friction grooves to increase the friction between the fixed plate and the workpiece. The clamping assembly and the fixed plate together fix the workpiece, so that the workpiece is double-clamped. During workpiece processing, it is ensured that the workpiece is not easy to slip or deviate, thereby improving the accuracy and quality of workpiece processing.

[0018] A torsion spring applies a thrust to the rotating plate, causing one end of the rotating plate to abut against the mounting plate. Simultaneously, a limit groove is provided on the bottom surface of the rotating plate, and the inner wall of the limit groove limits the adjustment strip, making it difficult for the limit strip to move. This further ensures that the moving plate and the locking block are not easily moved, and the locking block is not easily dislodged from the slot. This improves the stability of the fixing box, the arc plate, and the fixing plate, making it less likely for the fixing plate to loosen when clamping and fixing the workpiece, and further improving the quality of workpiece processing.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0030] like Figures 1-5 As shown, this application provides an automatic clamping rotary spindle, including: a housing 1, a spindle 101 installed inside the housing 1, a clamping assembly 102 installed on the inner wall of one end of the spindle 101, and further including:

[0031] The fixing mechanism 2 is located on one side of the housing 1. The fixing mechanism 2 includes an arc plate 201 fixedly installed on the side of the clamping assembly 102. A fixing plate 202 is fixedly installed on the side of the arc plate 201. An adjusting strip 210 is provided on one side of the fixing plate 202. The fixing mechanism 2 is used to strengthen the clamping and fixing of the workpiece.

[0032] Specifically, such as Figures 1-5 As shown, the bottom surface of the fixed plate 202 is provided with multiple friction grooves, the top surface of the arc plate 201 is provided with a through groove 203, the side of the arc plate 201 is fixedly installed with a fixed box 204, the side of the clamping assembly 102 is provided with a sliding groove 212, and the inner wall of the sliding groove 212 is slidably connected to the outer wall of the fixed box 204.

[0033] In this embodiment, multiple friction grooves are provided on the bottom surface of the fixing plate 202 to increase the friction between the fixing plate 202 and the workpiece, ensuring that the workpiece is not easily loosened.

[0034] Specifically, such as Figures 1-5 As shown, two movable plates 205 are slidably installed on the inner wall of the fixed box 204. The two movable plates 205 are fixedly installed with locking blocks 206 on their respective sides away from each other. One end of each locking block 206 slides through the inner wall of the fixed box 204 and extends to the outer side of the fixed box 204. The inner walls on both sides of the slide groove 212 are respectively provided with slots 213, and the two locking blocks 206 are respectively engaged with the two slots 213.

[0035] In this embodiment: the two locking blocks 206 are respectively engaged with the two locking slots 213 to fix the fixing box 204, and further fix the arc plate 201 and the fixing plate 202.

[0036] Specifically, such as Figures 1-5 As shown, the two movable plates 205 are elastically connected to each other on the side by elastic members 208. Two limiting rods 207 are slidably installed on the side of the two movable plates 205, and the two ends of the two limiting rods 207 are fixedly connected to the inner walls of the two sides of the fixed box 204.

[0037] In this embodiment: the moving plate 205 is limited by the limiting rod 207, and the locking block 206 is further limited.

[0038] Specifically, such as Figures 1-5 As shown, two adjustment slots 209 are respectively opened through the inner wall of the fixed box 204 and the side of the arc plate 201. The side of the movable plate 205 is fixedly connected to one end of the adjustment strip 210. The sides of the two adjustment strips 210 are slidably connected to the inner walls of the two adjustment slots 209 respectively. Limiting posts 211 are slidably installed through the side of the adjustment strips 210. The two ends of the limiting posts 211 are fixedly connected to the inner walls of the adjustment slots 209.

[0039] In this embodiment, the position of the movable plate 205 is adjusted by the adjustment bar 210.

[0040] The limiting mechanism 3 is located on one side of the clamping assembly 102. The limiting mechanism 3 includes a rotating plate 302 located on one side of the clamping assembly 102. A limiting groove 306 is formed on the bottom surface of one side of the rotating plate 302. The limiting mechanism 3 is used to limit the adjustment bar 210.

[0041] Specifically, such as Figures 1-5 As shown, two fixing blocks 301 are fixedly installed on the inner wall of one side of the through groove 203, and a rotating shaft 304 is fixedly installed through the side of the rotating plate 302. The two ends of the rotating shaft 304 are rotatably connected to the sides of the two fixing blocks 301 through bearing seats.

[0042] In this embodiment, the rotating plate 302 can be rotated by the rotating shaft 304.

[0043] Specifically, such as Figures 1-5 As shown, a groove 303 is provided on the side of the rotating plate 302, and a torsion spring 305 is movably installed on the outer wall of the rotating shaft 304. The two ends of the torsion spring 305 are fixedly connected to the inner wall of the through groove 203 and the inner wall of the groove 303, respectively.

[0044] In this embodiment, a torsion spring 305 is provided to apply torque to the rotating plate 302.

[0045] Specifically, such as Figures 1-5 As shown, a pulling block 308 is fixedly installed on the top surface of the rotating plate 302, an installation plate 307 is fixedly installed on the inner wall of the through groove 203, and two limiting grooves 306 are provided. The inner walls of the two limiting grooves 306 are slidably connected to the outer walls of the two adjusting strips 210 respectively, and the bottom surface of one side of the rotating plate 302 abuts against the top surface of the installation plate 307.

[0046] In this embodiment, the adjusting bar 210 is limited by the limiting groove 306 to ensure that the adjusting bar 210 is not easily moved.

[0047] Specifically, the solution involves: pushing the arc-shaped plate 201 and moving the fixed box 204 into the slide groove 212. Under the pressure of the slide groove 212, the locking block 206 drives the moving plate 205 to move and presses against the elastic element 208. When the locking block 206 moves to the slot 213, under the elastic force of the elastic element 208, it pushes the moving plate 205 and the locking block 206 to move. The locking block 206 engages with the slot 213, thereby fixing the fixed box 204 and the arc-shaped plate 201, and further fixing the fixed plate 202. The bottom surface of the fixed plate 202 is provided with multiple friction grooves to increase the friction between the fixed plate 202 and the workpiece. The clamping assembly 102 and the fixed plate 202 jointly fix the workpiece, so that the workpiece is double-clamped. During workpiece processing, to ensure that the workpiece does not easily slip or deviate, thereby improving the accuracy and quality of workpiece processing, a torsion spring 305 applies a pushing force to the rotating plate 302, causing one end of the rotating plate 302 to abut against the mounting plate 307. At the same time, since the bottom surface of the rotating plate 302 is provided with a limiting groove 306, and the inner wall of the limiting groove 306 limits the adjusting strip 210, the adjusting strip 210 is not easy to move. This further ensures that the moving plate 205 and the locking block 206 are not easy to move, and the locking block 206 is not easy to fall out of the locking groove 213, thereby improving the stability of the fixing box 204, the arc plate 201 and the fixing plate 202. This makes it less likely for the fixing plate 202 to loosen when clamping and fixing the workpiece, further improving the quality of workpiece processing.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
