[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) This utility model uses a rotating mechanism to drive a vertical rack to move upward in a straight line on a vertical slide rail when the angle of the tooling needs to be adjusted. At the same time, the gear and the vertical rack provide kinetic energy to the entire mechanism. The axial rotation of the entire mechanism is achieved through the concentric bearing seats at both ends. The rotation angle of the rotating mechanism is controlled by adjusting the stroke of the vertical cylinder and the movement of the vertical rack, which can meet the production needs of various working conditions and improve production capacity. At the same time, the tooling can be switched by removing the bolts to meet the production of various products. It is no longer a workstation that can only produce a single product. The end of the limit pin on the right support is driven by the horizontal cylinder to insert into the insertion hole to limit the tooling in the flat position, ensuring safe production and improving the utilization rate of the supporting workstation equipment. Casters are added under the entire rotating mechanism to facilitate the movement and maintenance of the equipment.

[0017] (2) The present invention uses a limiting component designed to limit the extension column by means of an arc-shaped plate when the tooling frame rotates to different angles, thereby limiting the left-turning column and the tooling frame, preventing the work frame from rotating unexpectedly, and increasing the stability and safety during use.

Detailed Implementation

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Example 1

[0026] Please see Figures 1-4 This utility model provides a technical solution: a pneumatically controlled automatic axial rotation device, including a tooling frame 102 and a rotation mechanism. The tooling frame 102 is fixedly connected to the left support 200 and the right support 206 by bolts. The rotation mechanism includes the left support 200, the right support 206 and the base frame 100. The left support 200 and the right support 206 are respectively arranged on both sides of the base frame 100. The base frame 100 is arranged at the bottom of the tooling frame 102. The top of the left support 200 and the right support 206 are both fixedly provided with bearing seats 201. The left rotating column 207 and the right rotating column 205 are respectively fixedly provided on both sides of the tooling frame 102, and the ends of the left rotating column 207 and the right rotating column 205 pass through the interior of the bearing seat 201.

[0027] A vertical cylinder 208 is fixedly installed on the left support 200. The vertical cylinder 208 can drive the vertical rack 212 to move up and down. The working end of the vertical cylinder 208 is fixedly installed with the vertical rack 212. The top of the vertical rack 212 extends to the outer side of the top of the left support 200.

[0028] A gear 211 is fixedly sleeved on the outside of the left-turning column 207. The gear 211 meshes with the vertical rack 212. A vertical slide rail 213 is fixedly installed on the top of the left bracket 200. When the vertical rack 212 moves up and down in the vertical slide rail 213, the vertical slide rail 213 can limit the vertical rack 212. The vertical rack 212 is located inside the vertical slide rail 213.

[0029] A horizontal cylinder 203 is fixedly installed on the top of the right bracket 206. The horizontal cylinder 203 can control the tooling frame 10 in a horizontal position. A limit pin 202 is fixedly installed at the working end of the horizontal cylinder 203 to limit one side 2 of the tooling frame 102 and increase its safety. An insertion hole 204 is provided, and the end of the limit pin 202 passes through the interior of the insertion hole 204.

[0030] The base frame 100 is equipped with four sets of casters 101 at the bottom, which facilitates the movement and maintenance of the equipment. The left bracket 200 and the right bracket 206 are both connected to adjusting screws 209 by threads. When placed on uneven ground, the adjusting screws 209 are turned up or down to move the base block 210 up and down, increasing the stability when placed. The base block 210 is fixedly installed at the bottom of the adjusting screws 209.

[0031] This utility model utilizes a designed rotating mechanism. When the angle of the tooling frame 102 needs adjustment, a vertical cylinder 208 drives a vertical rack 212 to move linearly upwards on a vertical slide rail 213. Simultaneously, a gear 211, in conjunction with the rack 212, provides kinetic energy to the entire mechanism. The axial rotation of the entire mechanism is achieved through concentric bearing seats 201 at both ends. The rotation angle of the rotating mechanism is controlled by adjusting the stroke of the vertical cylinder 208 and the movement of the rack 212, meeting the production needs of various working conditions and increasing production capacity. Furthermore, the tooling frame 102 can be switched by removing bolts, accommodating the production of multiple products and no longer being limited to a single product. On the right support 206, a horizontal cylinder 203 drives the end of a limiting pin 202 to insert into a socket 204, limiting the tooling frame 102 in a flat position to ensure safe production and improve the utilization rate of the supporting workstation equipment. Additionally, casters 101 are added below the entire rotating mechanism to facilitate equipment movement and maintenance.

[0032] Example 2

[0033] Please refer to Example 1. Figure 1 , Figure 3 , Figure 4 and Figure 5 A limiting component is provided between the top of the left support 200 and the left rotating column 207. The limiting component includes a vertical plate 304 fixed to the top of the left support 200 and an extension column 300 fixed to the end of the left rotating column 207.

[0034] The interior of the vertical plate 304 is connected by two sets of horizontal studs 303 by threads. The exterior of the extension column 300 is provided with an arc-shaped clamping plate 301. The outer wall of the arc-shaped clamping plate 301 is fixedly provided with two sets of mounting bearings 305. The ends of the horizontal studs 303 extend into the interior of the mounting bearings 305.

[0035] The top of the vertical plate 304 is connected to two sets of vertical studs 302 by threads. The vertical studs 302 can limit the horizontal studs 303 and limit the arc-shaped clamping plate 301, so as to prevent the arc-shaped clamping plate 301 from moving due to accidental rotation of the horizontal studs 303. The bottom of the vertical studs 302 extends to the surface of the horizontal studs 303.

[0036] This utility model, through the design of the limiting component, can limit the extension column 300 by the arc-shaped clamping plate 301 when the tooling frame 102 rotates to different angles, thereby limiting the left-turning column 207 and the tooling frame 102, preventing the work frame 102 from rotating unexpectedly, and increasing the stability and safety during use.

[0037] Working principle and usage process of this utility model:

[0038] When this utility model is in use, after the tooling frame 102 has fixed the automotive parts and is being processed, if it is necessary to adjust the axial angle of the tooling frame 102, the horizontal cylinder 203 is first activated. By controlling the opening and closing of the air source, valves, and other devices, the extension and retraction of the working end of the vertical cylinder 203 can be achieved. This allows the horizontal cylinder 203 to control the automatic axial rotation of the tooling frame 102 to adjust its angle. At this time, the working end of the horizontal cylinder 203 drives the limit pin 202 to move to the right, and then the end of the limit pin 202 disengages from the insertion hole 204. Then, the vertical cylinder 208 is activated. At this time, the working end of the vertical cylinder 208 drives the vertical rack 212 to move upward or downward in the vertical slide rail 213. At this time, the gear 211 meshing with it rotates, causing the left rotating column 207 to rotate along the axial direction of the left rotating column 207 and the right rotating column 205. This can drive the tooling frame 102 and the right rotating column 205 to rotate to a certain angle, so that the angle of the tooling frame 102 can be adjusted, making it convenient for the automotive parts fixed on the tooling frame 102 to be processed. After the processing is completed, the tooling frame 102 can be returned to its original position by operating in the opposite way.

[0039] To prevent accidental rotation of the fixture 102 after it has been rotated to a certain angle, the two sets of horizontal studs 303 on the vertical plate 304 are rotated toward the extension column 300, causing the arc-shaped clamping plate 301 to move. Then, the inner wall of the arc-shaped clamping plate 301 contacts and clamps the extension column 300. Then, the vertical studs 302 are rotated in opposite directions so that their bottoms contact and clamp the horizontal studs 303, thereby limiting the left-turning column 207 and thus limiting the fixture 102. When the fixture 102 needs to be rotated, the reverse principle is followed to ensure that the inner wall of the arc-shaped clamping plate 301 no longer contacts the outer wall of the extension column 300, so that the fixture 102 can be rotated.

[0040] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
