Abstract
Description
Technical Field
[0001] This utility model belongs to the field of valve processing technology, and in particular relates to a valve external polishing device. Background Technology
[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters (temperature, pressure, and flow rate) of the conveyed medium. Valves require grinding during the manufacturing process.
[0003] During the production and processing of valve castings, the outer surface of the finished valve castings is relatively rough and does not meet the requirements of production standards. Therefore, workers need to manually use handheld polishing machines to grind the outer wall of the valve castings to achieve a polishing effect. However, considering that manual grinding is not only inefficient, but also prone to uneven grinding of the outer wall of the valve castings, the polishing standards of the valve castings cannot be met, which affects the overall production quality of the valve castings. Therefore, a valve external polishing device is proposed. Utility Model Content
[0004] The purpose of this invention is to provide an external valve polishing device to solve the problems mentioned in the background art.
[0005] In view of this, the present invention provides an external valve polishing device, comprising:
[0006] A base plate has a fixed platform fixedly installed on its top surface and a movable platform slidably installed on its top surface. Mounting platforms are fixedly installed on the top surfaces of both the movable platform and the fixed platform. Fixed plates are fixedly installed on the top surfaces of both mounting platforms. A second turntable is rotatably installed on one side of one of the fixed plates, and a first turntable is rotatably installed on one side of the other fixed plate. A side frame is fixedly installed on the top surface of the base plate, and a lifting platform is slidably installed on one side of the side frame. A grinding machine is fixedly installed on the bottom surface of the lifting platform.
[0007] Two arc-shaped abutment plates are slidably mounted on one side of the second turntable. A valve body is provided between the two fixed plates. The outer sidewalls of the two arc-shaped abutment plates abut against the inner sidewalls of the valve body, respectively.
[0008] An adjustment component is disposed on the second turntable and is used to move two arc-shaped abutment plates.
[0009] A side rod is fixedly installed on one side of the first turntable. A clamping block is fixedly installed at one end of the side rod, and one end of the clamping block abuts against the outer wall of the valve body. When grinding the valve body surface, the fixed platform is placed on two arc-shaped clamping plates. Based on the diameter of the valve body's inner wall, an electric push rod is activated, pushing a moving block. As the moving block moves, the two arc-shaped clamping plates move through the cooperation of two second mounting seats, two connecting rods, and two first mounting seats, adjusting the distance between the two arc-shaped clamping plates. When the two arc-shaped clamping plates abut against the inner wall of the valve body, the valve body is fixed. At this point, a second telescopic cylinder is activated, driving the moving platform to move. The moving platform moves the clamping block, and one end of the clamping block abuts against the surface of the valve body, preventing the valve body from detaching from the two arc-shaped clamping plates during processing and increasing the stability of the valve body during processing.
[0010] In the above technical solution, the adjusting component further includes a U-shaped frame, which is fixedly installed on one side of the second turntable. A moving block is slidably installed inside the lifting platform. A second mounting seat is fixedly installed on both the top and bottom surfaces of the moving block. A connecting rod is fixedly installed on each of the two arc-shaped abutment plates. An electric push rod is rotatably installed in each of the two second mounting seats. The other ends of the two electric push rods are respectively rotatably installed in the two first mounting seats. When the moving block moves, the two arc-shaped abutment plates are pushed to move by the cooperation of the two second mounting seats, the two connecting rods, and the two first mounting seats, thereby adjusting the distance between the two arc-shaped abutment plates. When the two arc-shaped abutment plates abut against the inner wall of the valve body, the valve body is fixed.
[0011] In the above technical solution, an electric push rod is further fixedly installed on one side of the inside of the U-shaped frame. One end of the electric push rod is fixedly connected to one end of the moving block. When the electric push rod is activated, it pushes the moving block to move.
[0012] In the above technical solution, a motor is further fixedly installed on the top surface of one of the mounting platforms. One end of the motor output shaft is fixedly connected to one side of the second turntable. When the motor is started, the motor will drive the second turntable to rotate. When the second turntable rotates, the valve body will also rotate because the two arc-shaped abutting plates abut against the inside of the valve body, thereby adjusting the grinding surface of the valve body and enhancing the convenience of grinding.
[0013] In the above technical solution, a second telescopic cylinder is further fixedly installed on the top surface of the base plate. One end of the second telescopic cylinder is fixedly connected to one end of the moving table. When the second telescopic cylinder is activated, it drives the moving table to move. When the moving table moves, it will drive the abutment block to move. At this time, one end of the abutment block will abut against the surface of the valve body, thereby preventing the valve body from falling off the two arc-shaped abutment plates during processing and increasing the stability of the valve body during processing.
[0014] In the above technical solution, furthermore, the surfaces of the two arc-shaped abutting plates and abutting blocks are provided with anti-slip textures. By providing anti-slip textures, the friction force when the two arc-shaped abutting plates and abutting blocks abut against the valve body can be enhanced, thereby enhancing the fixation of the valve body when clamping it.
[0015] In the above technical solution, a first telescopic cylinder is further fixedly installed on the top surface of the side frame. The bottom end of the first telescopic cylinder passes through the outer side wall of the side frame and is fixedly connected to the top surface of the lifting platform. The lifting platform is raised and lowered by the first telescopic cylinder, which facilitates the grinding machine to approach the valve body.
[0016] The beneficial effects of this utility model are:
[0017] 1. In this valve external polishing equipment, when polishing the valve body surface, the fixed platform is placed on two arc-shaped abutment plates. According to the diameter of the inner wall of the valve body, the electric push rod is activated, which pushes the moving block to move. When the moving block moves, the two arc-shaped abutment plates are pushed to move through the cooperation of two second mounting seats, two connecting rods, and two first mounting seats. The distance between the two arc-shaped abutment plates is adjusted. When the two arc-shaped abutment plates abut against the inner wall of the valve body, the valve body is fixed. At this time, the second telescopic cylinder is activated, which drives the moving platform to move. When the moving platform moves, it will drive the abutment block to move. At this time, one end of the abutment block will abut against the surface of the valve body, thereby preventing the valve body from falling off the two arc-shaped abutment plates during processing and increasing the stability of the valve body during processing.
[0018] 2. This valve external polishing equipment can polish the surface of the valve body using a polishing machine. The first telescopic cylinder drives the lifting platform to move up and down, making it easier for the polishing machine to approach the valve body. At the same time as polishing, the motor is started, which drives the second turntable to rotate. When the second turntable rotates, the two arc-shaped clamping plates abut against the inside of the valve body, which also drives the valve body to rotate, adjusting the polishing surface of the valve body and enhancing the convenience of polishing.
