Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, and in particular to a feeding device for grinding the outer diameter of a plunger core. Background Technology

[0002] Before being used in conjunction with a hydraulic cylinder, the plunger core (piston rod) needs to be ground on its outer diameter. When a large number of plunger cores need to be rough ground in the early and middle stages, a centerless grinder is used for outer diameter grinding.

[0003] In the prior art, patent document CN218194143U discloses a feeding device for a centerless grinder, including a grinding wheel, an adjusting guide wheel, and a workpiece support roller located between the grinding wheel and the adjusting guide wheel for supporting a cylindrical workpiece. A mounting frame is provided on one side of the workpiece support roller, and a V-shaped support plate is mounted on the upper side of the mounting frame. The V-shaped support plate is horizontally positioned on one side of the workpiece support roller, allowing the cylindrical workpiece to be placed on the upper side of the V-shaped support plate. The V-shaped support plate on one side of the workpiece support roller allows for pre-positioning of the cylindrical workpiece. A Y-shaped support plate is provided on the V-shaped support plate, and a feeding mechanism moves the Y-shaped support plate to push the cylindrical workpiece onto the workpiece support roller for grinding. This device is simple and convenient to use, greatly improving its working efficiency, and also avoids requiring personnel to be close to the grinding equipment, thus reducing safety hazards.

[0004] During use, it was found that after the above-mentioned device completes the pushing of a workpiece, the mechanism needs to return to the starting point before the next operation can be performed. The cycle time is relatively long, and the feeding rhythm is not very consistent, which affects the conveying efficiency. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a plunger core outer diameter grinding and feeding device to improve conveying efficiency.

[0006] This utility model discloses a feeding device for grinding the outer diameter of a plunger core, comprising a counterweight box, a conveyor frame, a baffle plate, a support frame, a first guide plate, and a second guide plate. The support frame is mounted on the top of the counterweight box, and the conveyor frame is mounted on the side of the support frame. One end of the first guide plate is connected to one end of the second guide plate. Both the first and second guide plates are installed inside the support frame at an angle to the horizontal plane. The device also includes a lifting assembly, a conveying assembly, and a guiding assembly. The first guide plate is equipped with a guiding assembly, a lifting assembly, and a conveying assembly. The conveyor frame is equipped with baffles. In use, with the assistance of the guide assembly, the operator arranges multiple sets of piston rods neatly on the first guide plate, starts the conveying and lifting assemblies, the lifting assembly lifts the first set of piston rods onto the conveying assembly, the conveying assembly transports the first set of piston rods, the lifting assembly resets, the second set of piston rods moves to the original position of the first set of piston rods under its own gravity, the lifting assembly lifts the second set of piston rods onto the conveying assembly, realizing continuous feeding of piston rods. The operator only needs to arrange multiple sets of piston rods neatly on the first guide plate with the help of the guide assembly, improving the convenience of operation.

[0007] Preferably, the lifting assembly includes a servo electric cylinder, a connecting plate, and a lifting plate. A square opening is provided on the first guide plate, and a servo electric cylinder is located at the outer end of the second guide plate. A connecting plate is located at the bottom moving end of the servo electric cylinder, and the connecting plate is connected to the bottom end of the lifting plate. The lifting plate slides within the square opening, and its top end is flush with the inner end of the first guide plate. When the servo electric cylinder extends, the first set of piston rods moves to the top of the lifting plate under its own weight. The servo electric cylinder then shortens, causing the connecting plate to drive the lifting plate along the inner end of the second guide plate, lifting the first set of piston rods onto the conveying assembly. When the servo electric cylinder extends again, the top end of the lifting plate is flush with the inner end of the first guide plate again, and the second set of piston rods rolls to the top of the lifting plate, achieving continuous lifting of the piston rods.

[0008] Preferably, the conveying assembly includes a drive motor, conveying rollers, auxiliary rollers, a conveyor belt, rubber blocks, V-grooves, and guide frames. Two sets of conveying rollers and multiple sets of auxiliary rollers are rotatably arranged inside the conveyor frame, with the auxiliary rollers positioned between the two sets of conveying rollers. The drive motor is mounted on the conveyor frame, and its output end is connected to one end of one set of conveying rollers. A conveyor belt is fitted around the outer sides of the two sets of conveying rollers. Multiple sets of rubber blocks are evenly spaced on the outer wall of the conveyor belt. Each set of rubber blocks has a V-groove at its top along the rotation direction of the conveyor belt. Two sets of guide frames are symmetrically arranged at the top of the conveyor frame, with their inner ends close to the ends of the rubber blocks. The inner distance between the two sets of guide frames is slightly larger than the diameter of the piston rod. When the drive motor is started, the two sets of conveying rollers, in conjunction with the multiple sets of auxiliary rollers, drive the conveyor belt to rotate. After the lifting plate lifts the piston rod, the piston rod rolls under its own weight and, guided by the two sets of guide frames, rolls onto the conveyor belt. The multiple sets of rubber blocks support and convey the piston rod through their respective V-grooves, achieving continuous feeding of the piston rod.

[0009] Preferably, the guide assembly includes a positioning plate, a block, a lead screw, and a nut. The first guide plate has a strip-shaped opening. There are two sets of positioning plates. Each set of positioning plates has a block at its bottom. A lead screw is located at the end of each block away from the positioning plate. The lead screw passes through an annular flat washer and is threadedly connected to the nut. The distance between the two sets of positioning plates is adjusted by sliding the block in the strip-shaped opening according to the length of the piston rod. After adjustment, the nut is threadedly connected to the lead screw. Rotating the nut causes it to press against the outer end of the first guide plate through the annular flat washer, thus completing the positioning of the two sets of positioning plates. The piston rod is then placed between the two sets of positioning plates, with the distance between the two sets of positioning plates slightly greater than the length of the piston rod, so that the piston rod is neatly placed horizontally.

[0010] Preferably, the device also includes adjustable feet, with a set of adjustable feet provided at each of the four corners of the bottom of the counterweight box; the four sets of adjustable feet work together to provide stable support for the device and improve its stability.

[0011] Preferably, it also includes a reinforcing plate, and a reinforcing plate is provided between the counterweight box and the conveyor frame; the counterweight box supports the conveyor frame through the reinforcing plate to prevent deformation of the conveyor frame and improve its service life.
