Description

Technical Field

[0001] The utility model relates to the technical field of valve body processing, in particular to a valve body processing device. Background Art

[0002] As we all know, the definition of valve body including valve is a device used to control the direction, pressure and flow of fluid in the fluid system. Valve is a device that allows the medium (liquid, gas, powder) in the piping and equipment to flow or stop and control its flow. When drilling the flange parts on the valve body, a processing device is required.

[0003] The patent with publication number CN216858315U proposes a valve body processing device, including a processing table, an n-shaped vertical plate is fixed on the top of the processing table, two symmetrically arranged electric push rods are fixed on the top of the n-shaped vertical plate, the telescopic ends of the electric push rods all pass through the n-shaped vertical plate, and are fixedly connected to the same n-shaped lifting rod, a synchronous drilling mechanism is installed on the n-shaped lifting rod, and a positioning mechanism is installed on the top of the processing table. This valve body processing device, different from the prior art, utilizes a synchronous drilling mechanism to realize multiple punching operations simultaneously, without the need for manual hand-held punching tools to perform punching operations, with high punching efficiency and effect, greatly improving the quality of punching, secondly, utilizing the positioning mechanism, while the n-shaped lifting rod drives the synchronous drilling mechanism to move down for drilling, the flange component can be clamped and positioned in advance, and then there is no need to manually clamp the flange component with a clamp before performing the punching operation, thereby reducing the operation steps and improving work efficiency.

[0004] When the above structure is in use, there is a lack of a limiting structure at the drill rod. When the drill rod is lowered, the drill rod is easily misplaced on the circular plate, which will affect the stability of the drill rod when in use. Moreover, when the drill rod is damaged, it is not easy to replace it. Utility Model Content

The workpiece body 2 can be positioned on the processing table 1 through the clamping assembly, and the motor 14 can be started to drive the driven wheel 11 to rotate through the meshing effect. At this time, multiple drill bits 9 will rotate together, and then the lifter 6 is started to make the top plate 7 and the bottom plate 8 descend at a uniform speed, so that the drill bit 9 can descend at a uniform speed, and then the workpiece body 2 can be punched. In this process, the driven wheel 11 can be provided with a limiting effect through the support rod 12, so as to improve the stability of the drill bit 9 during rotation.
