Description

Technical Field

[0001] This utility model relates to a positioning and clamping device, specifically a positioning and clamping device for processing hydraulic components, belonging to the field of hydraulic cylinder production technology. Background Technology

[0002] Hydraulic cylinders are essential components in the operation of large equipment. The piston rod in a hydraulic cylinder is the connecting part that supports the piston in performing work. It is a moving part with frequent movement and high technical requirements. The quality of its processing directly affects the lifespan and reliability of the entire product. The main feature of a hydraulic piston rod is that it is a slender shaft. When producing a hydraulic piston rod, its surface needs to be polished to remove burrs, which facilitates its subsequent use. During the polishing process, the hydraulic cylinder piston rod needs to be clamped and fixed to ensure the quality of polishing.

[0003] A search revealed an existing patent number: 202320887111.3, which describes a hydraulic piston rod polishing device. The hydraulic piston rod to be polished is passed through a moving block and placed inside two mounting boxes. The locking cylinder is activated, which drives the C-shaped limiting plate to move back and forth, thereby restricting the outer surface of the hydraulic piston rod to facilitate subsequent grinding and polishing.

[0004] However, while the device uses two cylinders to clamp and fix the piston rod at both ends, it lacks clamping components, making it prone to loosening during polishing. Furthermore, the device lacks positioning components when limiting the piston rod, resulting in the piston rod not being on the same center as the polishing components after clamping. This requires repeated manual correction, which is cumbersome, time-consuming, and prone to errors. These errors can lead to deviations during polishing, affecting the quality of the piston rod and rendering it unusable in severe cases. Utility Model Content

[0005] The purpose of this invention is to provide a positioning and clamping device for hydraulic component processing to solve the above-mentioned problems. By installing a threaded sleeve and a threaded rod, piston rods of different lengths can be placed and loaded. By rotating the rotating sleeve on the threaded sleeve and the threaded rod, the rotating sleeve drives multiple drive rods to abut against multiple clamping blocks, so that multiple clamping blocks simultaneously clamp the piston rod. The piston rod is clamped at the center inside the threaded sleeve and the threaded rod, which facilitates the grinding component to accurately grind the piston rod and reduce errors. By tightening multiple screws, the rotating sleeve is limited, and the clamping blocks tightly clamp the piston rod.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a positioning and clamping device for processing hydraulic components, comprising a polishing frame and a grinding assembly mounted on the polishing frame. A clamping mechanism is installed at the end of the polishing frame, the clamping mechanism including a threaded sleeve. A threaded sleeve is threadedly connected to the center of one end of the polishing frame, and a threaded rod is threadedly connected to the other end of the polishing frame. Positioning mechanisms are respectively installed at the opposite ends of the threaded rod and the threaded sleeve. The positioning mechanisms include movable grooves. Multiple movable grooves are respectively provided on the sidewalls of the opposite ends of the threaded rod and the threaded sleeve. Drive rods are respectively provided inside the multiple movable grooves. Rotary sleeves are rotatably connected to the outer sides of the opposite ends of the threaded rod and the threaded sleeve. Multiple drive rods are rotatably connected to the inner sidewalls of the rotary sleeves. Clamping blocks are respectively provided on the inner sides of the opposite ends of the threaded rod and the threaded sleeve. The other ends of the multiple drive rods are rotatably connected to the center of the multiple clamping blocks. The angle between the drive rods and the clamping blocks is 45 degrees. Screws are respectively vertically threaded to the outer sides of the rotary sleeves.

[0007] Preferably, a drive disk is mounted on one end of each of the plurality of screws, and the drive disk has a hexagonal structure.

[0008] Preferably, the plurality of clamping blocks have an arc-shaped structure, and a toothed plate is installed on one side of the plurality of clamping blocks.

[0009] Preferably, the outer side of one end of the threaded sleeve is provided with multiple slots, and a baffle is slidably connected inside one of the slots.

[0010] Preferably, the top of the baffle extends to the outside of the threaded sleeve, and a groove is provided on the outer side of the top of the baffle, the groove being an elliptical structure.

[0011] Preferably, both the threaded rod and the threaded sleeve are cylindrical "I"-shaped structures, the length of the threaded sleeve is greater than the length of the threaded rod, and the diameters of the threaded sleeve and the threaded rod are equal.

[0012] Preferably, the threaded sleeve and the threaded rod are perpendicularly connected to one end of a plurality of push rods, and one end of the push rods has a spherical structure to facilitate the installation of piston rods of different lengths.

[0013] Preferably, a protective pad is installed on the inner side of one end of the threaded rod, and the protective pad is a disc-shaped rubber material.

[0014] Preferably, the threaded sleeve is a hollow cylindrical structure, and one end of the threaded sleeve is rotatably connected to a plurality of ball bearings that are distributed in an annular pattern at equal intervals.

[0015] The beneficial effects of this utility model are as follows: By installing the threaded sleeve, it is convenient to insert the piston rod into the threaded sleeve for feeding. By pushing the piston rod, the piston rod slides inside the threaded sleeve and extends through the grinding assembly to the inner side of one end of the threaded rod, realizing convenient feeding of the piston rod. Then, by rotating the threaded sleeve and the threaded rod, it is convenient to install piston rods of different lengths. Finally, by rotating the rotating sleeve on the threaded sleeve and the threaded rod, the rotating sleeve drives multiple drive rods to abut against multiple clamping blocks, so that multiple clamping blocks simultaneously clamp the piston rod, so that the piston rod is clamped at the center inside the threaded sleeve and the threaded rod, which facilitates the grinding assembly to accurately grind the piston rod and reduce errors. After the piston rod is clamped by multiple clamping blocks, the screw on the outside of the rotating sleeve is rotated to limit the rotating sleeve, so that the clamping blocks clamp the piston rod tightly, which facilitates stable polishing.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6 As shown, a positioning and clamping device for processing hydraulic components includes a polishing frame 1 and a grinding assembly 2 mounted on the polishing frame 1. A clamping mechanism 3 is installed at the end of the polishing frame 1. The clamping mechanism 3 includes a threaded sleeve 301. The threaded sleeve 301 is threadedly connected to the center of one end of the polishing frame 1, and a threaded rod 302 is threadedly connected to the other end of the polishing frame 1. Positioning mechanisms 4 are respectively installed at the opposite ends of the threaded rod 302 and the threaded sleeve 301. The positioning mechanism 4 includes a movable groove 406. Multiple movable grooves 4 are respectively provided on the side walls of the opposite ends of the threaded rod 302 and the threaded sleeve 301. 06. Each of the multiple movable slots 406 is provided with a drive rod 407. The outer sides of the opposite ends of the threaded rod 302 and the threaded sleeve 301 are rotatably connected to the rotating sleeve 401. The multiple drive rods 407 are rotatably connected to the inner side wall of the rotating sleeve 401. The inner sides of the opposite ends of the threaded rod 302 and the threaded sleeve 301 are provided with clamping blocks 405. The other ends of the multiple drive rods 407 are rotatably connected to the center of the multiple clamping blocks 405. The included angle between the drive rods 407 and the clamping blocks 405 is 45 degrees. The outer side of the rotating sleeve 401 is vertically threaded with a screw 404.

[0025] As a technical optimization of this utility model, a drive disk 402 is installed at one end of each of the multiple screws 404. The drive disk 402 has a hexagonal structure. The installation of the drive disk 402 facilitates the drive control of the screws 404, making operation convenient and preventing slippage.

[0026] As a technical optimization of this utility model, the multiple clamping blocks 405 have an arc-shaped structure, and a toothed plate 403 is installed on one side of the multiple clamping blocks 405, which is conducive to the stable clamping of the piston rod on the outside, and at the same time increases the friction and plays a role in preventing slippage.

[0027] As a technical optimization of this utility model, the outer side of one end of the threaded sleeve 301 is provided with multiple slots 305, and a baffle 306 is slidably connected inside one of the slots 305. The opening of multiple slots 305 facilitates the installation of the baffle 306, so as to achieve contact with the end of the piston rod. With the cooperation of the threaded rod 302, the two ends of the piston rod are tightly contacted. By changing different slots 305, contact with piston rods of different lengths can be achieved.

[0028] As a technical optimization of this utility model, the top of the baffle 306 extends to the outside of the threaded sleeve 301, and the top outer side of the baffle 306 is provided with a groove 307. The groove 307 has an elliptical structure, which is conducive to holding and pulling the baffle 306, so as to realize the disassembly and assembly of the baffle 306.

[0029] As a technical optimization of this utility model, both the threaded rod 302 and the threaded sleeve 301 are cylindrical "I" shaped structures. The length of the threaded sleeve 301 is greater than the length of the threaded rod 302, and the diameters of the threaded sleeve 301 and the threaded rod 302 are equal. This helps prevent the threaded rod 302 and the threaded sleeve 301 from slipping out, thus playing a limiting role and facilitating the placement of different piston rods.

[0030] As a technical optimization of this utility model, multiple push rods 303 are vertically connected to the opposite ends of the threaded sleeve 301 and the threaded rod 302. One end of the push rod 303 has a spherical structure. By installing multiple push rods 303, the threaded sleeve 301 and the threaded rod 302 can be driven and controlled, thereby adjusting their positions and facilitating the installation of piston rods of different lengths.

[0031] As a technical optimization of this utility model, a protective pad 308 is installed on the inner side of one end of the threaded rod 302. The protective pad 308 is a disc-shaped rubber material. The installation of the protective pad 308 facilitates tight contact with the piston rod and plays a role in preventing wear.

[0032] As a technical optimization of this utility model, the threaded sleeve 301 is a hollow cylindrical structure. Multiple ball bearings 304 arranged in annular and equidistant arrangement are rotatably connected to one end of the threaded sleeve 301, which facilitates the feeding of the piston rod and allows the piston rod to slide smoothly inside the threaded sleeve 301 without wear.

[0033] In use, the polishing frame 1 is first installed stably. Then, the piston rod to be polished is inserted into one end of the threaded sleeve 301. The piston rod slides inside the threaded sleeve 301 via the ball bearing 304, thus feeding the piston rod. By pushing the piston rod, it extends through the polishing assembly 2 to the inner side of one end of the threaded rod 302, where it contacts the protective pad 308, facilitating easy feeding of the piston rod. Then, the position of the threaded sleeve 301 is rotated according to the length of the piston rod. Next, the baffle 306 is inserted into the appropriate slot 305. By rotating the rotating sleeve 401 on the outside of the threaded sleeve 301 and the threaded rod 302, the rotating sleeve 401 drives the piston rod. Multiple drive rods 407 abut against multiple clamping blocks 405, causing the clamping blocks 405 to simultaneously clamp the piston rod, so that the piston rod is clamped at the center inside the threaded sleeve 301 and the threaded rod 302. At this time, the piston rod is located at the center inside the grinding assembly 2, which facilitates the grinding assembly 2 to accurately grind the piston rod and reduce errors. Finally, the threaded sleeve 301 or the threaded rod 302 is rotated again to achieve tight contact between the two ends of the piston rod. Then, the screws 404 on the outside of the two rotating sleeves 401 are rotated to limit the rotating sleeves 401, so that the clamping blocks 405 clamp the piston rod tightly, which facilitates stable polishing of the piston rod.
