Description

Technical Field

[0001] This utility model relates to the technical field of piston ring processing equipment, specifically a piston ring trimming machine with a quick-change grinding wheel. Background Technology

[0002] Piston rings are widely used in various power machinery, such as steam engines, diesel engines, gasoline engines, compressors, and hydraulic presses. They are also widely used in automobiles, trains, ships, and yachts. After the initial processing, the outer wall of the piston ring cut is relatively rough and needs to be polished. A finishing machine is required when processing piston rings.

[0003] A piston ring trimming machine (authorization announcement number CN215239957U) is disclosed in the patent database. It includes a fixed base, a fixed plate, a slider, a guide rod, a push plate, an adjusting screw, a turntable, a grinding wheel, and a motor. The fixed base has a fixing assembly. The slider is slidably mounted on the fixed plate, and the guide rod is slidably mounted on the fixed plate and connected to the slider. The push plate is mounted on two sets of guide rods, and the adjusting screw is threadedly connected to a support and passes through the support to rotate with the push plate. The turntable and gear disk are rotatably mounted on the sliders on the two sets of fixed plates, and are connected by a mounting plate. The motor is mounted on the mounting plate and powered by the grinding wheel. The adjusting gear is rotatably mounted on the fixed plate via a rotating shaft and meshes with the gear disk for transmission. A movable sleeve is slidably connected to a fixed block, and a spring is mounted on the fixed block and abuts against the movable sleeve. This invention allows for arbitrary angle adjustment of the grinding wheel, offering a wide adjustment range, good flexibility, and broad applicability.

[0004] Currently, most finishing machines used for piston ring processing typically use flanges and bolts to connect and fix the grinding wheels during operation. This installation method requires twisting multiple bolts to disassemble and replace the grinding wheels, making the operation cumbersome and inconvenient for quick disassembly, resulting in relatively poor practicality. Summary of the Invention

[0005] The purpose of this invention is to provide a piston ring finishing machine with a quick-change grinding wheel, in order to solve the problems mentioned in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a piston ring finishing machine with quick-change grinding wheels, comprising a processing table, a three-jaw chuck installed at the center of the top of the processing table, a linear module one symmetrically arranged on the top of the processing table, a bracket connected above the linear module one, a linear module two connected together at the upper ends of the two brackets, symmetrically arranged hydraulic cylinders connected below the linear module two, a connecting plate connected to the telescopic end of the hydraulic cylinders, a motor connected below the connecting plate via an angle adjustment assembly, a grinding wheel connected to the output end of the motor via a fixing mechanism, the fixing mechanism including a positioning plate, and the positioning plate being fixedly sleeved on the outer side of the output end of the motor, near the side of the grinding wheel close to the motor, a plurality of fixing rods symmetrically arranged on one side of the positioning plate, and all fixing rods penetrating the grinding wheel, a fixing plate being provided on the side of the grinding wheel away from the positioning plate, and a plurality of through holes adapted to the fixing rods being symmetrically opened at one end of the fixing plate.

[0007] Furthermore, the fixing mechanism also includes a limiting plate, which is rotatably installed inside the fixing plate. One end of the connecting shaft of the limiting plate is connected to a handle outside the fixing plate. The side wall of the limiting plate has symmetrically formed grooves that fit the fixing rods. The outer wall of the fixing rods has a limiting groove that fits the limiting plate. Two fixing blocks are installed on the inner wall of the fixing plate and one side of the limiting plate, and the two fixing blocks are located between two adjacent fixing rods. A guide rod is fixedly installed between the two fixing blocks. A spring and a baffle are sleeved on the outer side of the guide rod from bottom to top, and the baffle is fixedly connected to the limiting plate. A limiting block is fixedly installed inside the fixing plate, and the limiting block is located on one side between the two fixing blocks. The outer wall of the limiting plate has symmetrically formed chambers, and each chamber contains a post and a spring. The post is located near the edge of the limiting plate. The inner wall of the limiting groove has a hole that fits the post. The fixing mechanism allows for convenient and quick disassembly and replacement of the grinding wheel, making it easy to use and more practical.

[0008] Furthermore, the angle adjustment component includes a mounting bracket located outside the motor. A connecting rod is connected to the top of the mounting bracket, and the upper end of the connecting rod is hinged to the connecting plate via a ball joint. A fixed bracket is fitted around the outside of the motor, and both ends of the fixed bracket are rotatably connected to the inner wall of the mounting bracket. A gear is connected to one end of the fixed bracket outside the mounting bracket, and a rack is meshed with one side of the gear. A telescopic rod is connected to the upper end of the rack, and the telescopic rod is fixedly connected to the mounting bracket. The side of the mounting bracket away from the telescopic rod is movably connected to the bottom of the connecting plate via a second telescopic rod. The angle adjustment component allows for adjustment of the grinding wheel's tilt angle in the left-right and front-back directions as needed, making it more versatile, capable of multi-angle processing, and more practical.

[0009] Furthermore, a hexagonal prism is fixedly installed on one end of the fixed disk near the positioning disk, and a hexagonal groove adapted to the hexagonal prism is opened at the output end of the motor so as to connect the fixed disk and the motor, so that the fixed disk can rotate synchronously with the output end of the motor.

[0010] Furthermore, the groove is arc-shaped, the guide rod is arc-shaped and the guide rod is concentric with the limiting plate, and the insertion post is a T-shaped column structure so as to guide the baffle through the guide rod, thereby guiding the limiting plate.

[0011] Furthermore, the mounting frame is U-shaped, and the two ends of the telescopic rod are respectively hinged to the connecting plate and the mounting frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through a fixing mechanism, allows the limiting disc to rotate by twisting the handle, which in turn drives the baffle to compress the spring, aligning the groove on the limiting disc with the fixing rod. Then, it can be pulled to one side to separate the fixing disc from the fixing rod. After that, the grinding wheel can be pulled to one side to complete the disassembly. Disassembly is quick. During installation, after the grinding wheel is sleeved on the outside of the fixing rod, the above steps are repeated to align the groove on the limiting disc with the through hole before installing the fixing disc. The fixing rod is then inserted into the fixing disc. Releasing the force applied to the handle allows the limiting disc to reset and snap into the limiting groove, thus fixing the grinding wheel. This allows for convenient and quick disassembly and assembly of the grinding wheel, making it more practical.

[0014] 2. This utility model, through the angle adjustment component, allows for convenient adjustment of the tilt angle of the grinding wheel in all directions, making it suitable for multi-angle processing, with a wider range of applications and greater practicality. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] Example: Figure 1 - Figure 5As shown, this utility model provides a technical solution: a piston ring trimming machine with quick-change grinding wheels, including a processing table 1. A three-jaw chuck 5 is installed at the middle of the top of the processing table 1. A linear module 1 2 is symmetrically arranged on the top of the processing table 1. A bracket 3 is connected above the linear module 1 2. The upper ends of the two brackets 3 are connected to a linear module 2 4. A hydraulic cylinder 6 is symmetrically arranged below the linear module 2 4. A connecting plate 7 is connected to the telescopic end of the hydraulic cylinder 6. A motor 8 is connected below the connecting plate 7 through an angle adjustment component. A grinding wheel 9 is connected to the output end of the motor 8 through a fixing mechanism. The fixing mechanism includes a positioning plate 10, and the positioning plate 10 is fixedly sleeved on the side of the grinding wheel 9 near the motor 8 outside the output end of the motor 8. A number of fixing rods 12 are symmetrically arranged on one side of the positioning plate 10, and the fixing rods 12 all penetrate the grinding wheel 9. A fixing plate 11 is arranged on the side of the grinding wheel 9 away from the positioning plate 10, and a number of through holes adapted to the fixing rods 12 are symmetrically opened at one end of the fixing plate 11. In this example, the fixing mechanism also includes a limiting plate 13, which is rotatably mounted inside the fixing plate 11. One end of the connecting shaft of the limiting plate 13 is connected to a handle on the outside of the fixing plate 11. The side wall of the limiting plate 13 has symmetrically formed grooves that fit the fixing rods 12. The outer wall of the fixing rods 12 has a limiting groove that fits the limiting plate 13. Two fixing blocks 14 are installed on the inner wall of the fixing plate 11 and one side of the limiting plate 13, and the two fixing blocks 14 are located between two adjacent fixing rods 12. A guide rod 15 is fixedly installed between the two fixing blocks 14. The outer side of the guide rod 15 extends from the bottom... The upper sleeve is equipped with a spring 16 and a baffle 17, and the baffle 17 is fixedly connected to the limiting plate 13. A limiting block 28 is fixedly installed inside the fixed plate 11, and the limiting block 28 is located on one side between the two fixed blocks 14. The outer wall of the limiting plate 13 has symmetrically opened chambers, and the chambers are equipped with a post 18 and a spring 19. The post 18 is located on one side near the edge of the limiting plate 13. The inner wall of the limiting groove has an insertion hole that matches the post 18. The setting of the fixing mechanism allows for convenient and quick disassembly and replacement of the grinding wheel 9, making it convenient to use and more practical. In this example, the angle adjustment component includes a mounting bracket 21 located outside the motor 8. A connecting rod 22 is connected to the top of the mounting bracket 21, and the upper end of the connecting rod 22 is hinged to the connecting plate 7 via a ball joint. A fixing bracket 26 is fitted on the outside of the motor 8, and both ends of the fixing bracket 26 are rotatably connected to the inner wall of the mounting bracket 21. A gear 25 is connected to one end of the fixing bracket 26 outside the mounting bracket 21. A rack 24 is meshed on one side of the gear 25. A telescopic rod 23 is connected to the upper end of the rack 24, and the telescopic rod 23 is fixedly connected to the mounting bracket 21. The side of the mounting bracket 21 away from the telescopic rod 23 is movably connected to the bottom of the connecting plate 7 via a telescopic rod 27. The angle adjustment component allows for adjustment of the tilt angle of the grinding wheel 9 in the left-right and front-back directions as needed, making it more applicable, capable of multi-angle processing, and more practical.

[0023] In this example, a hexagonal prism 20 is fixedly mounted on one end of the fixed plate 11 near the positioning plate 10. The output end of the motor 8 has a hexagonal groove adapted to the hexagonal prism 20 to connect the fixed plate 11 and the motor 8, allowing the fixed plate 11 to rotate synchronously with the output end of the motor 8. In this example, the groove is arc-shaped, the guide rod 15 is arc-shaped, and the guide rod 15 is concentric with the limiting plate 13. The insertion post 18 has a T-shaped column structure to guide the baffle 17 via the guide rod 15, thereby guiding the limiting plate 13. In this example, the mounting bracket 21 is U-shaped. The two ends of the telescopic rod 27 are hinged to the connecting plate 7 and the mounting bracket 21 respectively. One side of the mounting bracket 21 has a guide sleeve for limiting and guiding the rack 24, so as to transmit power and adjust the angle of the motor 8. The guide sleeve guides and limits the rack 24.

[0024] The working principle of this utility model is as follows: During use, after adjusting the height of the piston rings with the three-jaw chuck 5, the position of the grinding wheel 9 is adjusted left-right and forward-backward using linear modules 1 and 2. Combined with the hydraulic cylinder 6 adjusting the height of the grinding wheel 9, multi-station machining is possible. When the grinding wheel 9 needs to be disassembled and replaced, one hand can limit the grinding wheel 9, while the other hand twists the handle to drive the limiting plate 13 to rotate. This causes the limiting plate 13 to drive the baffle 17 to slide along the guide rod 15 and compress the spring 16. When the baffle 17 contacts the limiting block 28, the groove is aligned with the fixing rod 12. Then, the handle is pulled. Remove the fixed plate 11 from the fixed rod 12, causing the fixed plate 11 to separate the hexagonal prism 20 from the output end of the motor 8. Then, the grinding wheel 9 can be removed from the output end of the motor 8, completing the disassembly. When installing the grinding wheel 9, first install the grinding wheel 9 on the output end of the motor 8 and the outside of the fixed rod 12. Then, repeat the disassembly steps described above, turning the handle to drive the limiting plate 13 to rotate, so that the groove on the limiting plate 13 is aligned with the fixed rod 12. Then, place the fixed plate 11 on the outside of the fixed rod 12, inserting one end of the fixed plate 11 into the fixed plate 12, and then remove the hexagonal prism 20. The column 20 is inserted into the hexagonal slot on the output end of the motor 8. Then, the force applied to the handle is released, causing the baffle 17 to drive the limiting plate 13 to rotate and reset under the elastic force of the spring 16. This causes the groove on the limiting plate 13 to be misaligned with the fixing rod 12, and the limiting plate 13 to engage with the limiting groove on the fixing rod 12. The insertion column 18 is aligned with the insertion hole. When the motor 8 drives the grinding wheel 9 to rotate, the insertion column 18 will pull the spring 19 under the action of centrifugal force, and one end of the insertion column 18 will be inserted into the corresponding insertion hole, thereby further strengthening the connection between the limiting plate 13 and the fixing rod 12. The connection enhances the restraining and fixing effect of the fixing rod 12. When it is necessary to adjust the angle of the grinding wheel 9, the rack 24 can be moved by activating the telescopic rod 23, which drives the meshing gear 25 to drive the fixing frame 26 to rotate the motor 8 in the front and back directions, thereby adjusting the tilt angle of the grinding wheel 9 in the front and back directions. The mounting frame 21 and the connecting rod 22 can be extended and retracted by activating the telescopic rod 27, thereby rotating the mounting frame 21 and the connecting rod 22 around the ball head in a circular shape to the left or right, thereby adjusting the tilt angle of the grinding wheel 9 in the left and right directions, enabling it to perform multi-angle processing, with a wider range of applications and stronger practicality.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
