A turntable positioning mechanism

Abstract

This utility model discloses a turntable positioning mechanism, including a base with a housing fixedly connected to its front side. Through a transmission assembly and a clamping assembly, a motor is started, a worm gear rotates, driving a worm wheel to rotate, the worm wheel rotates, driving a rotating rod to rotate, the rotating rod drives a rotating shaft to rotate, and the rotating shaft rotates, driving a rotating disk to rotate. When the rotating disk rotates, a rotating column slides inside a rotating hole in the rotating disk, causing a moving block to slide along the arc of the rotating hole. During this sliding process, the moving plate clamps and fixes the surface of the workpiece. This solves the problem that existing turntables require multiple positioning components for workpiece positioning before placing the workpiece on the turntable for fixation. This method is time-consuming and labor-intensive, requiring different positioning components for different workpieces, which is inconvenient and prevents quick workpiece fixation.

Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, specifically a turntable positioning mechanism. Background Technology

[0002] Turntables are commonly used equipment in mechanical manufacturing, enabling the positioning and processing of workpieces at different angles. The positioning method of a turntable refers to the way information such as the workpiece's position and angle is determined during its use.

[0003] The existing turntable requires multiple positioning components for workpiece positioning. The current operation involves first placing the positioning component into the through hole at the top of the turntable, and then placing the workpiece on the turntable for fixing. This method is time-consuming and labor-intensive, and different positioning components need to be replaced for different workpieces, which is inconvenient and cannot quickly fix the workpiece.

[0004] Therefore, the turntable needs to be redesigned to effectively prevent the current operating procedure of first placing the positioning component into the through hole at the top of the turntable, and then placing the workpiece on the turntable for fixing. This method is time-consuming and labor-intensive, requires different positioning components for different workpieces, and is inconvenient, as it cannot quickly fix the workpiece.

It solves the problem that existing turntables require multiple positioning components for workpiece positioning. The current operation involves first placing the positioning component into the through hole on the top of the turntable, and then placing the workpiece on the turntable for fixing. This method is time-consuming and labor-intensive, and different positioning components need to be replaced for different workpieces, which is inconvenient and cannot quickly fix the workpiece.

As the rotating disk rotates, the rotating column slides inside the rotating hole, causing the moving block to slide along the arc of the rotating hole. During this sliding process, the moving plate clamps and fixes the surface of the workpiece. This solves the problem that existing turntables require multiple positioning components for workpiece positioning. The current operation involves first placing the positioning component into the through hole at the top of the turntable, and then placing the workpiece on the turntable for fixing. This method is time-consuming and labor-intensive, and different positioning components need to be replaced for different workpieces, which is inconvenient and cannot quickly fix the workpiece.

[0024] As a technical optimization of this utility model, by setting the transmission component 10, after starting the servo motor 3, the worm gear 101 is driven to rotate, the worm gear 101 rotates, the worm wheel 102 rotates, the worm wheel 102 rotates, the rotating rod 5 rotates, the rotating rod 5 rotates, the rotating shaft 6 rotates, and the rotating shaft 6 rotates, the rotating disk 9 rotates, resulting in higher transmission efficiency and smoother operation.

[0025] refer to Figure 1 and Figure 4 The clamping assembly 11 includes a fixed plate 111, which is fixedly connected to the top of the workbench 7. There are four fixed plates 111. A movable plate 112 is slidably connected to the surface of the fixed plate 111. A rotating column 113 is fixedly connected to the bottom of the movable plate 112. A rotating hole 114 is opened on the top of the rotating disk 9. The rotating column 113 is slidably connected to the rotating hole 114.

[0026] As a technical optimization of this utility model, by setting the clamping component 11, when the rotating disk 9 rotates, the rotating column 113 slides inside the rotating hole 114 opened inside the rotating disk 9, causing the moving plate 112 to slide along the arc of the rotating hole 114, and the moving plate 112 can more effectively clamp and fix the surface of the workpiece.

[0027] refer to Figure 2 The fixing component 12 includes a support column 121, which is fixedly connected to the surface of the base 1. There are four support columns 121. A limit groove 122 is opened on the top of the support column 121. A support rod 123 is movably connected inside the limit groove 122. The support rod 123 is fixedly connected to the bottom of the worktable 7.

[0028] As a technical optimization of this utility model, the fixed component 12 can fix the workbench 7, and the limiting groove 122 opened on the top of the support column 121 makes it easier to disassemble and repair the workbench 7.

[0029] refer to Figure 1 The front of the chassis 2 has ventilation holes 13, and a dust filter 14 is fixedly connected inside the ventilation holes 13.

[0030] As a technical optimization of this utility model, the heat dissipation hole 13 can dissipate heat when the motor is working, extend the service life of the motor, and the dustproof mesh 14 inside the heat dissipation hole 13 can prevent external dust from entering the chassis 2.

[0031] refer to Figure 1 The base 1 is threadedly connected to the top of the base cover 15, and the rotating rod 5 extends through to the top of the base cover 15.

[0033] refer to Figure 3 The bottom of the working groove 4 is fixedly connected to a limiting plate 16. There are two limiting plates 16, and the worm gear 101 is slidably connected to the limiting plate 16.

[0034] As a technical optimization of this utility model, the limiting plate 16 can limit the worm 101, preventing the worm 101 from shifting position during rotation, thus avoiding the phenomenon of disengaging from the worm wheel 102 and interrupting the transmission.

[0035] The working principle and usage process of this utility model are as follows: First, place the workpiece on the worktable 7. Then, start the motor to make the worm gear 101 rotate. The rotation of the worm gear 101 drives the worm wheel 102 to rotate, which in turn drives the rotating rod 5 to rotate. The rotating rod 5 drives the rotating shaft 6 to rotate, which in turn drives the rotating disk 9 to rotate. When the rotating disk 9 rotates, the rotating column 113 slides inside the rotating hole 114 within the rotating disk 9, causing the moving plate 112 to slide along the arc of the rotating hole 114. During the sliding process, the moving plate 112 clamps and fixes the surface of the workpiece. Through the four moving plates 112, the workpiece can be more stably fixed, effectively preventing the workpiece from shaking and achieving a highly efficient clamping effect.

The current operation involves first placing the positioning component into the through hole at the top of the turntable, and then placing the workpiece on the turntable for fixing. This method is time-consuming and labor-intensive, requiring different positioning components for different workpieces, which is inconvenient and prevents quick workpiece fixing.
