Description

Technical Field

[0001] The invention patent relates to the field of machinery, and in particular to a rotary worktable for mechanical processing. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates (usually less than 6mm), including shearing, punching / cutting / combining, folding, welding, riveting, splicing, forming (such as car body), etc. Its most notable feature is that the thickness of the same part is consistent.

[0003] Sheet metal parts have the characteristics of light weight, high strength, conductivity (can be used for electromagnetic shielding), low cost, and good performance in large-scale mass production. They have been widely used in the fields of electronics, communications, automobile industry, medical equipment, etc. For example, sheet metal parts are an indispensable component in computer cases, mobile phones, and MP3s.

[0004] In existing production process activities, sheet metal parts are usually taken to the processing station of the riveting machine for riveting during the riveting process, but this is only for small sheet metal parts. If riveting is performed on different parts of a large sheet metal part, more workers are required to lift the sheet metal part, and then an operator performs the riveting work. After one part is riveted, these multiple workers rotate the angle and move to other processing positions. After the processing position is placed on the processing position, the riveting operator performs the riveting work. Such processing requires a lot of manpower, wastes the physical strength of the workers, reduces work efficiency, and increases the fatigue of the operators, bringing hidden dangers to safe production.

[0005] The purpose of this patent is to provide a rotary worktable for mechanical processing, which has the advantages of using a motor to drive the worktable to rotate, a cylinder to achieve workpiece clamping and limiting, and reducing manual operation.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: A rotary table for machining, comprising a base, a groove is provided at the center of the base, a driving motor is provided in the groove and faces upward, a fixedly connected reinforcing shaft is provided on the output shaft of the driving motor, a fixedly connected working table is provided on the top of the reinforcing shaft, a limiting mechanism is provided on the surface of the working table, the limiting mechanism comprises a first limiting groove, a second limiting groove, a third limiting groove and a fourth limiting groove arranged on the surface of the working table, a first pushing cylinder, a second pushing cylinder, a third pushing cylinder and a fourth pushing cylinder respectively arranged on the first limiting groove, the second limiting groove, the third limiting groove and the fourth limiting groove, and a limiting block on a piston rod arranged on the first pushing cylinder, the second pushing cylinder, the third pushing cylinder and the fourth pushing cylinder, the first limiting groove, the second limiting groove, the third limiting groove and the fourth limiting groove are distributed in a cross shape; a reinforcing block is installed on the surface of the limiting block, and an anti-slip groove is provided on the surface of the reinforcing block.

[0007] By adopting the above technical solution, starting the drive motor can drive the workbench on the upper reinforcement shaft to rotate, which is convenient for multi-angle and all-round processing of sheet metal parts. At the same time, the limiting mechanism on the surface of the workbench can clamp and fix the sheet metal parts: the pushing cylinders set in four directions work synchronously, driving the limiting blocks on the piston rod to clamp and fix the workpiece at the center, and the reinforcing blocks and anti-slip grooves set on the surface of the limiting blocks can further increase the friction resistance of the sheet metal parts, so that the sheet metal parts can maintain a relatively stable work position for easy processing.

[0008] Further configuration: a support mechanism is also provided under the workbench, the support mechanism includes a plurality of support shafts provided at the bottom of the workbench, a universal roller provided at the bottom of the support shaft, and a sliding groove matching the universal roller is provided on the surface of the base.

[0009] By adopting the above technical solution, the supporting mechanism arranged under the workbench is used to support and protect the workbench above. On the one hand, through the supporting shaft and the universal roller at the bottom, the roller in the sliding groove can cooperate with the driving motor to drive the rotation of the workbench. On the other hand, it alleviates the supporting pressure of the reinforcing shaft on the driving motor.

[0010] Further configuration: a padding block is provided at the center of the workbench, a processing table fixedly connected to the padding block is provided, and a plurality of shock-absorbing springs are provided at the bottom of the processing table.

[0011] By adopting the above technical solution, the raising block arranged at the center of the workbench is used to increase the working position of the sheet metal part, making it higher than the horizontal plane of the entire workbench, which is convenient for the processing of the staff, and the shock-absorbing spring at the bottom of the processing table can further alleviate the vibration of the processing table caused by the operation of the driving motor.

[0012] It is further configured that: the base is provided with a control switch group connected to the drive motor, the first push cylinder, the second push cylinder, the third push cylinder and the fourth push cylinder.

[0013] By adopting the above technical solution, the staff can control the start and stop of the drive motor, the first push cylinder, the second push cylinder, the third push cylinder and the fourth push cylinder through the control switch group, which is simple and effective.

[0014] It is further provided that: a rotatably connected shift lever is provided on the surface of the sliding groove.

[0015] By adopting the above technical solution, when the driving motor drives the workbench to rotate to a specified angle, the staff can limit the position of the support shaft by rotating the connected gear lever to prevent it from rotating.

[0016] In summary, the patent of the present invention has the following beneficial effects: this type of rotating platform is suitable for precise processing of sheet metal parts. The bottom drives the entire workbench to rotate at a uniform speed through a driving motor, and the angle can be adjusted according to work requirements. At the same time, a limiting fixing mechanism is also provided on the workbench. Through the synchronous operation of the pushing cylinders in four directions, precise clamping and limiting of sheet metal parts can be achieved, greatly improving the processing efficiency.
