Description

Technical Field

[0001] This utility model relates to the technical field of grinding and polishing equipment, specifically a grinding device with an efficient grinding disc replacement mechanism. Background Technology

[0002] A piston pump is an important component of a hydraulic system. It relies on the reciprocating motion of a piston within a cylinder to change the volume of the sealed working chamber, thus achieving oil suction and pressure. Piston pumps offer advantages such as high rated pressure, compact structure, high efficiency, and convenient flow rate adjustment. They are widely used in high-pressure, high-flow-rate applications requiring flow rate regulation, such as hydraulic presses, construction machinery, and ships. The stroke block is a crucial component of the piston pump; its main function is to adjust the piston's stroke, thereby controlling the pump's output flow rate. The stroke block is typically located at the drive end of the piston pump and is closely connected to the crank-connecting rod mechanism and the stroke adjustment mechanism. Adjusting the position of the stroke block changes the piston's stroke length.

[0003] When machining the stroke block in a plunger pump, the outer wall of the stroke block needs to be ground and polished. Because grinding and polishing requires the continuous rotation of the grinding disc, the grinding disc wears out quite severely, requiring frequent replacement. Traditional grinding equipment used for grinding and polishing stroke blocks typically uses bolts to connect the shaft that drives the grinding disc to the grinding disc, making disassembly inconvenient and affecting the efficiency of grinding disc replacement. This also affects the processing efficiency of the stroke block, resulting in relatively poor practicality. Utility Model Content

[0004] The purpose of this invention is to provide a grinding device with an efficient grinding disc replacement mechanism to solve the problems raised in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grinding device with a high-efficiency grinding disc replacement mechanism, comprising a processing table, with clamps symmetrically arranged on the top of the processing table, and several pillars rectangularly distributed on the top of the processing table. A horizontal and vertical adjustment device is connected above the pillars, and a telescopic rod is connected to the middle position below the horizontal and vertical adjustment device.

One end of the limiting sleeve is attached to the side wall of the push plate near the push column. A through groove adapted to the combination mechanism of the limiting sleeve and the limiting block is opened on one side of the fixed base to limit and fix the push column, so as to prevent the locking rod from moving due to centrifugal force during the operation of the grinding disc, thereby affecting the installation and fixing effect of the grinding disc.

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.

[0020] Example: Figure 1 - Figure 4As shown, this utility model provides a technical solution: a grinding device with a high-efficiency grinding disc replacement mechanism, including a processing table 1. The top of the processing table 1 is symmetrically equipped with clamps. Several pillars 2 are rectangularly distributed on the top of the processing table 1. A horizontal and vertical adjustment device 3 is connected above the pillars 2. A telescopic rod 4 is connected to the middle position below the horizontal and vertical adjustment device 3. The telescopic end of the telescopic rod 4 is connected to a motor 5 with a housing through an adjustment component. The output end of the motor 5 is connected to a grinding disc 6 through a replacement mechanism. In this example, the horizontal and vertical adjustment device 3 consists of a symmetrically arranged longitudinal electric slide rail and a transverse electric slide rail. Its specific model and specifications can be selected according to actual needs, as long as it can realize the position adjustment of the motor 5 in the front-back, left-right and right directions. The replacement mechanism includes a drive shaft 9, which is located below the motor 5. The upper end of the drive shaft 9 is fixedly connected to the output end of the motor 5. A connecting shaft 7 is provided below the drive shaft 9. The upper end of the connecting shaft 7 is inserted into a slot opened at the bottom of the grinding disc 6. The lower end of the connecting shaft 7 is fixedly connected to the grinding disc 6. In this example, the replacement mechanism also includes a fixed seat 8, which is fixedly sleeved on the outside of the drive shaft 9. The fixed seat 8 has a hollow structure, and slide rods 10 are symmetrically arranged inside the fixed seat 8. A locking rod 11 is symmetrically arranged between the two slide rods 10, and the two ends of the locking rod 11 are slidably sleeved on the outside of the two slide rods 10. The outer walls of the drive shaft 9 and the connecting shaft 7 are respectively provided with notches and slots 20 that are adapted to the locking rods 11. A push plate 12 is provided on one side of the fixed seat 8, and a push column 15 is connected to one side of the push plate 12. One end of the push column 15 extends to the outside of the fixed seat 8. A connecting rod 13 is movably connected to the other side of the push plate 12 at symmetrical positions, and one end of each rod is movably connected to one end of a locking rod 11. One side of the push plate 12 is fixedly connected to the slide rod 10 located on the right side by a spring 14. The setting of the replacement mechanism makes it convenient and quick to disassemble, replace and install the grinding disc 6, improve the work efficiency of replacing the grinding disc 6 and the processing efficiency of the stroke block, and is easy to use and more practical. In this example, a limiting sleeve 16 is rotatably sleeved on the outer side of the push column 15 located outside the fixed base 8. A torsion spring 17 is sleeved inside the limiting sleeve 16 on the outer side of the push column 15, and the two ends of the torsion spring 17 are fixedly connected to the push column 15 and the limiting sleeve 16 respectively. A limiting block 18 is symmetrically provided on the outer wall of the limiting sleeve 16 near the fixed base 8. A limiting frame 19 is provided on the outer side of the limiting block 18, and the limiting frame 19 is fixedly connected to the fixed base 8. One end of the limiting sleeve 16 is attached to the side wall of the push plate 12 near the push column 15. A through groove adapted to the combination mechanism of the limiting sleeve 16 and the limiting block 18 is opened on one side of the fixed base 8 so as to limit and fix the push column 15, and prevent the clamping rod 11 from moving due to centrifugal force during the operation of the grinding disc 6, thereby affecting the installation and fixing effect of the grinding disc 6.

[0021] In this example, the adjustment assembly includes a support plate 21, which is fixedly connected to the telescopic end of the telescopic rod 4. A fixed rod 22 is movably connected to the middle of the bottom of the support plate 21, and the lower end of the fixed rod 22 is fixedly connected to the housing of the motor 5. Telescopic rods 23 are movably connected to symmetrical positions at the bottom of the support plate 21, and the telescopic ends of the telescopic rods 23 are movably connected to the housing of the motor 5. The adjustment assembly is designed to allow for adjustment of the tilt angle of the grinding disc 6 as needed, adapting to multi-angle grinding processes. In this example, the limiting frame 19 is L-shaped. The two limiting frames 19 are vertically distributed with the corresponding slots of the limiting block 18 in the through groove, and the two limiting frames 19 are symmetrically arranged to limit and support the limiting block 18. In this example, telescopic rod 4 is a hydraulic telescopic rod, and telescopic rod 23 is an electric telescopic rod. The two ends of telescopic rod 23 are hinged to the support plate 21 and the housing of motor 5, respectively. The upper end of the fixing rod 22 is hinged to the bottom surface of the support plate 21, so as to support and fix motor 5 while also adjusting its angle.

[0022] The working principle of this utility model is as follows: When the grinding disc 6 needs to be disassembled and replaced, the limiting sleeve 16 can be rotated 90 degrees by twisting it, causing the limiting sleeve 16 to drive the connected limiting block 18 to rotate synchronously. At the same time, the limiting sleeve 16 will cooperate with the push column 15 to twist the torsion spring 17 until the combination mechanism of the limiting block 18 and the limiting sleeve 16 is aligned with the through groove. This pushes the limiting sleeve 16 to drive the push column 15 and the push plate 12 to move into the fixed seat 8, causing the push plate 12 to push the two connected connecting rods 13, and then push the two locking rods 11. Slide along the slide bar 10 to move the two locking rods 11 to the opposite side. After the locking rods 11 are moved out of the slot 20, pull down the grinding disc 6 and the connecting shaft 7 to remove the connecting shaft 7 from the drive shaft 9, completing the quick disassembly of the grinding disc 6. Then, a new grinding disc 6 can be replaced. During installation, repeat the above disassembly steps to move the locking rods 11 out of the drive shaft 9, and then insert the upper end of the connecting shaft 7 into the drive shaft 9. After that, gradually release the thrust applied to the limiting sleeve 16, so that the push plate 12 is spring-loaded by the spring 14. The force applied to the limiting sleeve 16 and connecting rod 13 causes them to reset, which in turn causes the connecting rod 13 to drive the connecting rod 11 to reset, allowing the connecting rod 11 to pass through the notch on the drive shaft 9 and enter the slot 20. At this time, the limiting block 18 also passes through the through slot and moves to the outside of the fixed seat 8. Then, the force applied to the limiting sleeve 16 is released, causing the limiting sleeve 16 to reset and rotate under the torque of the torsion spring 17. At the same time, the limiting sleeve 16 drives the limiting block 18, causing the limiting block 18 to engage inside the limiting frame 19, thereby allowing the limiting sleeve 16 to be reset. With the limit switch 6, the installation of the grinding disc 6 can be completed. This device allows for quick disassembly and replacement of the grinding disc 6, improving work efficiency. The position and angle of the grinding disc 6 can also be adjusted as needed. The horizontal and vertical adjustment device 3 can adjust the left and right and front and back positions of the grinding disc 6. By extending one telescopic rod 23 outward and retracting the other telescopic rod 23, the motor 5 can be adjusted to tilt the grinding disc 6, thereby changing the angle of the grinding disc 6, making it more applicable and more convenient to use.
