Description

Technical Field

[0001] This utility model relates to the field of polishing technology for hydraulic valve production, and more specifically, to a housing polishing device for hydraulic valve production. Background Technology

[0002] The hydraulic valve body is the core component of a hydraulic valve, and its surface finish directly affects the valve's sealing performance and assembly accuracy. Polishing is a critical process in hydraulic valve body production, requiring polishing of the outer surface, through holes, and threaded holes.

[0003] However, existing technologies still have the following problems: most existing polishing devices are single-station designs, with loading, polishing, and unloading performed sequentially, making continuous operation impossible; the polishing at the end of the threaded hole is incomplete, and the transition position between the threaded hole and the end face of the housing (i.e., the end) often has an arc or step structure. Conventional polishing tools (such as grinding wheels and polishing belts) cannot fit the curved surface, which easily leads to polishing dead corners, resulting in substandard surface finish and affecting the sealing performance of subsequent threaded connections. Utility Model Content

[0004] One objective of this invention is to provide a new technical solution for a housing polishing device used in the production of hydraulic valves.

[0005] According to a first aspect of the present invention, a housing polishing device for hydraulic valve production is provided, comprising a base, a rotating worktable mounted on the top of the base, a plurality of clamping mechanisms evenly distributed around the circumference of the rotating worktable, the clamping mechanisms being used to position and clamp the hydraulic valve housing, lifting brackets symmetrically mounted on both sides of the base, a main polishing mechanism being provided on the top of the lifting brackets, and a threaded hole finishing polishing mechanism being fixedly mounted on one side of the lifting brackets.

[0006] Optionally, the clamping mechanism includes a positioning seat, a positioning pin, and two clamping cylinders. The positioning seat is fixed to the top of the rotary table, and the positioning pin is vertically fixed to the top surface of the positioning seat. The positioning pin is used to fit with the positioning hole of the hydraulic valve housing. The clamping cylinders are symmetrically installed on both sides of the top of the positioning seat. An arc-shaped clamping block is fixed to the output end of the clamping cylinder. The inner wall of the arc-shaped clamping block fits with the outer wall of the hydraulic valve housing.

[0007] Optionally, the main polishing mechanism includes a lateral adjustment motor, a slide rail, and a positioning rod. The lateral adjustment motor is fixed on the outer side of the top of the lifting bracket. The slide rail is connected to the output shaft of the lateral adjustment motor. The positioning rod is disposed on both sides of the slide rail and fixedly installed on the inner side of the top of the lifting bracket. A slider is slidably mounted on the slide rail and the positioning rod. A polishing wheel drive motor is fixedly connected to the bottom of the slider. The output shaft of the polishing wheel drive motor is connected to a polishing wheel.

[0008] Optionally, the threaded hole finishing polishing mechanism includes a fixed bracket, an axial adjustment cylinder, a rotary drive motor, and a polishing rod. The fixed bracket is fixedly installed on the top of the base, the axial adjustment cylinder is installed on the fixed bracket, the rotary drive motor is connected to the output shaft of the axial adjustment cylinder, one end of the polishing rod is connected to the output shaft of the rotary drive motor, and the other end of the polishing rod is connected to a polishing head. A polishing sleeve is fitted on the rotary drive motor and the polishing rod, and the polishing sleeve is fixedly installed on one side of the axial adjustment cylinder.

[0009] Optionally, a mounting base is fixedly connected to the bottom of the base, and an indexing motor is fixedly connected to the mounting base. The output shaft of the indexing motor is fixedly connected to the bottom end of the rotary table.

[0010] According to one embodiment of this disclosure, a housing polishing device for hydraulic valve production uses a clamping mechanism to position and clamp the hydraulic valve housing. Then, an indexing motor drives a rotary table to rotate, sequentially sending the housing to the main polishing mechanism station to complete the outer surface polishing. The threaded hole finishing polishing mechanism station pushes the polishing head to fit the transition curved surface to complete the finishing polishing.

[0021] like Figure 1-3 As shown, a rotary worktable 2 is installed at the top of the base 1. Several clamping mechanisms 3 are evenly distributed in the circumferential direction of the rotary worktable 2. The main function of these clamping mechanisms 3 is to accurately position and clamp the hydraulic valve housing to be processed, ensuring its stability during processing. A pair of lifting brackets 5 are symmetrically installed on both sides of the base 1. A main polishing mechanism 4 is set on the top of the pair of lifting brackets 5 for polishing the surface of the hydraulic valve housing. In addition, a threaded hole finishing polishing mechanism 6 is fixedly installed on one side of the lifting bracket 5 to perform fine finishing polishing on the threaded holes on the housing.

[0022] like Figures 1 to 3As shown, the clamping mechanism 3 includes a positioning seat 301, a positioning pin 302, and two clamping cylinders 303. The positioning seat 301 is fixed to the top of the rotary table 2, and the positioning pin 302 is vertically fixed to the top surface of the positioning seat 301.

The rotary drive motor 603 is tightly connected to the output shaft of the axial adjustment cylinder 602 to ensure smooth power transmission. One end of the polishing rod 604 is connected to the output shaft of the rotary drive motor 603, and the other end is connected to a polishing head 605 for polishing operations, thereby realizing the polishing function. In order to protect the rotary drive motor 603 and the polishing rod 604, a polishing sleeve 606 is fitted on their exterior. The polishing sleeve 606 is fixedly installed on one side of the axial adjustment cylinder 602 to ensure its safety during operation.
