A quick positioning device for supporting inside a cylinder

Abstract

This utility model relates to the field of cylindrical positioning technology, and in particular to a rapid positioning device for an internal support of a cylindrical cylinder. It includes a mounting base, a positioning component on the top of the mounting base, and auxiliary components on the sides of the mounting base. Through the coordinated use of a bearing plate, a first motor, a bidirectional screw, an adjusting block, a positioning plate, and a friction pad, stable positioning of the workpiece is achieved, effectively preventing the workpiece from falling off or being damaged during processing. The bearing plate, as a supporting structure, firmly fixes the entire positioning component. The first motor drives the bidirectional screw to rotate, which in turn moves the adjusting block on the screw, realizing the opening and closing action between the positioning plates. The positioning plates directly act on the workpiece, ensuring a uniform distribution of clamping force, and can adapt to workpieces of different sizes and shapes. The friction pad further enhances the clamping effect, ensuring good positioning stability even when dealing with workpieces of different materials and specifications.

[0028] A quick positioning device for a cylindrical inner support includes a mounting base 1, a positioning component 2 on the top of the mounting base 1, and an auxiliary component 3 on the side of the mounting base 1. The positioning component 2 includes a support plate 201 on the top of the mounting base 1, an adjustment hole 202 at the bottom of the support plate 201, a first motor 203 mounted at the end of the support plate 201, a bidirectional screw 204 fixedly connected to the output end of the first motor 203, the bidirectional screw 204 passing through the support plate 201 and extending into the adjustment hole 202, the bidirectional screw 204 being rotatably connected to the support plate 201, an adjustment block 205 threadedly connected to the outer surface of the bidirectional screw 204, a positioning plate 206 fixedly connected to the bottom of the adjustment block 205, a friction pad 20 fixedly connected to the side of the positioning plate 206, and two positioning plates 206 being provided, with the two positioning plates 206 positioned opposite each other.

[0029] The two adjusting blocks 205 move in opposite or the same direction under the action of the bidirectional screw 204, which drives the opening and closing of the positioning plate 206, so that the positioning plate 206 can flexibly clamp or release the workpiece.

[0030] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the auxiliary component 3 includes an L-plate 301 on the side of the mounting base 1. A positioning hole 302 is provided on the side of the L-plate 301, and a second motor 303 is installed in the positioning hole 302. A mounting plate 304 is fixedly connected to the output end of the second motor 303. A vertical plate 305 is provided on the side of the mounting plate 304, and an auxiliary plate 306 is fixedly connected to the top of the vertical plate 305. An auxiliary groove 307 is provided on the top of the auxiliary plate 306. A support plate 201 is located on top of the auxiliary plate 306, and the bottom of the support plate 201 extends into the auxiliary groove 307 and slides within the auxiliary groove 307. Next, a second bolt 5 is provided on the top of the support plate 201. The second bolt 5 passes through the support plate 201 and extends into the auxiliary plate 306. The second bolt 5 is threadedly connected to the support plate 201. The L plate 301 is L-shaped. A first bolt 4 is provided on the side of the L plate 301. The first bolt 4 passes through the L plate 301 and extends into the mounting base 1. The first bolt 4 is threadedly connected to the L plate 301. A third bolt 6 is provided on the side of the upright plate 305. The third bolt 6 passes through the upright plate 305 and extends into the mounting plate 304. The third bolt 6 is threadedly connected to the upright plate 305.

[0031] The second motor 303 drives the mounting plate 304 and the upright plate 306 to rotate, which improves the flexibility of the positioning component 2.

[0032] The working process of this utility model is as follows: When using the cylindrical inner support quick positioning device designed in this scheme, first check whether the device is working properly. Fix the mounting base 1 in an appropriate working position so that the workpiece can be accurately positioned. Start the first motor 203, and rotate the bidirectional screw 204 to make the two adjusting blocks 205 move in opposite or the same direction under the action of the bidirectional screw 204, which drives the opening and closing of the positioning plate 206, so that the positioning plate 206 can flexibly clamp or release the workpiece. During the clamping process, the friction pad 207 plays a key role. It effectively increases the friction between the positioning plate 206 and the workpiece, preventing the workpiece from slipping during the gripping process, thereby ensuring the stability and reliability during operation. At the same time, with the cooperation of the auxiliary component 3, the working position and angle after positioning can be further adjusted to adapt to workpieces of different sizes and shapes. When precise positioning of the workpiece is required, the mounting plate 304 and the upright plate 306 can be rotated by the second motor 303, which not only improves the flexibility of the positioning component 2, but also greatly enhances its applicability and practicality.
