Description

Technical Field

[0001] This utility model relates to the technical field of grinding machine internal cylindrical grinding device for improving the smoothness of the inner wall of water distributor, and particularly to a grinding machine internal cylindrical grinding device for improving the smoothness of the inner wall of water distributor. Background Technology

[0002] In numerous industrial sectors such as oil extraction, chemical production, and water treatment, water distributors serve as crucial equipment for achieving uniform fluid distribution, and their performance directly impacts the operational efficiency and stability of the entire system. The core function of a water distributor is to precisely deliver fluid to various branch pipelines or treatment units according to preset requirements, and the realization of this function highly depends on the machining precision of its inner wall, especially the smoothness of the inner wall.

[0003] In the chemical production field, water distributors are commonly used in process steps such as reactor feeding and solvent distribution. Many chemical fluids are corrosive or contain impurities. If the inner wall of the water distributor has poor smoothness, it will not only increase the contact area between the fluid and the inner wall, accelerating the corrosion process and shortening the service life of the water distributor, but may also cause impurities to adhere to the rough inner wall surface, forming scale. This scale will not only further increase the fluid flow resistance and affect the distribution accuracy, but may also detach during subsequent production processes, mixing into the reaction system or products, affecting product quality, and even causing serious problems such as equipment blockage and process failure.

[0004] In the water treatment industry, water distributors are used to distribute the inlet water to equipment such as sedimentation tanks and filtration tanks. Insufficient smoothness of the inner wall can lead to unstable water flow within the distributor, resulting in localized areas with excessively fast or slow flow velocities. Areas with excessively fast flow erode the internal structure of the tank, damaging the filter layer or sedimentation environment; areas with excessively slow flow are prone to impurity deposition, affecting water treatment efficiency and effluent quality, and increasing the burden on subsequent treatment processes.

[0005] Traditional grinding machines often employ a single grinding head structure for internal grinding, and the feed adjustment precision of the grinding head is relatively low. When machining the inner diameter of water distributors of different specifications, it is difficult to accurately control the grinding depth and grinding speed, which can easily lead to over-grinding or under-grinding. The workpiece fixing mechanism of traditional grinding machines has poor stability, and the water distributor workpiece is prone to slight displacement or vibration during the grinding process, causing the grinding trajectory to deviate from the preset path. This not only fails to ensure the consistency of the inner wall surface finish but may also produce machining defects such as scratches and steps on the inner wall of the workpiece. Based on this, a grinding machine internal grinding device for improving the inner wall surface finish of water distributors is proposed to solve the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an internal grinding device for improving the surface finish of the inner wall of a water distributor. This device solves the problem that the workpiece fixing mechanism of traditional grinding devices has poor stability, and the workpiece of the water distributor is prone to slight displacement or vibration during the grinding process, causing the grinding trajectory to deviate from the preset path. This not only fails to guarantee the consistency of the inner wall surface finish, but may also produce processing defects such as scratches and steps on the inner wall of the workpiece.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an internal grinding device for improving the smoothness of the inner wall of a water distributor, comprising a fixed frame, an mounting plate fixedly installed on the upper section of the fixed frame, a cylinder fixedly installed on the front of the mounting plate, a push rod fixedly connected to the bottom output end of the cylinder, a receiving frame fixedly connected to the bottom of the push rod, a drive motor fixedly installed on the top of the receiving frame, a drive wheel fixedly connected to the outer wall of the shaft fixedly connected to the bottom output end of the drive motor, a transmission wheel one and a transmission wheel two connected to the outer wall of the drive wheel via a transmission belt, a transmission shaft fixedly connected to the inner wall of the transmission wheel one, a transmission rotating shaft fixedly connected to the inner wall of the transmission wheel two, a connecting box fixedly installed on the lower outer wall of the receiving frame, a grinding head fixedly connected to the bottom outer wall of the transmission rotating shaft, an adjusting motor fixedly installed on the bottom inner wall of the fixed frame, a drive shaft connected to the output end of the adjusting motor via a differential, a clamp fixedly installed on the top of the drive shaft, and a mounting plate fixedly connected to the lower section of the fixed frame.

[0008] A further improvement is that a connecting slider is fixedly connected to the back of the receiving frame, and a fixed slide rail is slidably connected to the inner wall of the back of the connecting slider. During the downward movement of the receiving frame, the connecting slider fixedly connected to the back of the receiving frame slides along the fixed slide rail fixedly connected to the outer wall of the front of the fixed frame. The fixed slide rail restricts and guides the movement direction of the connecting slider, thereby ensuring that the receiving frame always moves smoothly in the vertical direction and avoiding left and right deviation or swaying of the receiving frame during the movement.

[0009] A further improvement is that the fixed slide rail is fixedly connected to the outer wall of the front of the fixed frame.

[0010] A further improvement is that a limiting slide is provided in the middle section of the receiving frame, and the lower section of the transmission shaft is located in the inner cavity of the limiting slide. During the downward movement of the receiving frame, the connecting slider fixedly connected to the back of the receiving frame slides along the fixed slide rail fixedly connected to the outer wall of the front of the fixed frame. The fixed slide rail restricts and guides the movement direction of the connecting slider, thereby ensuring that the receiving frame always moves smoothly in the vertical direction and avoiding left and right deviation or swaying of the receiving frame during the movement.

[0011] A further improvement is that a limiting slide is provided on the outer side of the receiving frame, and the outer wall of the upper section of the transmission shaft is located in the inner cavity of the limiting slide. The limiting slide and the limiting slide in the middle section of the receiving frame work together to further limit the radial displacement of the transmission shaft and ensure the rotational stability of the transmission shaft.

[0012] A further improvement is that the lower section of the transmission shaft is rotatably connected to the inner wall of the connecting box; the lower section of the transmission shaft is rotatably connected to the inner wall of the connecting box, which is fixedly installed on the lower section of the supporting frame. The connecting box provides an additional support point for the transmission shaft, effectively reducing the vibration of the transmission shaft during high-speed rotation and ensuring that the transmission shaft can stably transmit the rotational power to the grinding head fixedly connected to the bottom outer wall.

[0013] A further improvement is that the grippers are fixedly installed on the inner wall of the mounting plate; when the grinding of the inner wall of the water distributor reaches the preset requirements, the system first controls the drive motor to stop running and the grinding head to stop rotating; then controls the cylinder to run in reverse, the push rod to retract, driving the receiving frame and the grinding head to move upward and exit the inner cavity of the water distributor workpiece; finally controls the regulating motor to run in reverse, driving the grippers to open through the differential and drive shaft, so that the operator can remove the processed water distributor workpiece and complete the entire grinding process.

[0014] By means of the above technical solution, this utility model provides an internal grinding device for improving the smoothness of the inner wall of a water distributor, which has at least the following beneficial effects:

[0015] 1. This utility model adjusts the motor and differential to drive the gripper to hold the workpiece, which can accurately control the clamping force and stability, and avoid the workpiece displacement or vibration during grinding. In the transmission link, the drive wheel drives the first and second transmission wheels to rotate synchronously through the transmission belt. Combined with the support of the connecting box for the transmission shaft and the guiding effect of the limiting slide, the vibration of the grinding head during high-speed rotation is greatly reduced, ensuring the accuracy of the grinding trajectory. The cylinder-driven receiving frame can be smoothly raised and lowered along the fixed slide rail through the connecting slider. With the slow rotation of the workpiece, it realizes all-round uniform grinding of the inner circle of the water distributor, which ultimately significantly improves the smoothness of the inner wall. It can meet the high precision requirements of water distributors in fields such as oil extraction and chemical production, reduce problems such as high fluid resistance, scaling and corrosion caused by rough inner wall, and extend the service life of the water distributor.

[0016] 2. When processing water distributors of different specifications, this utility model eliminates the need for frequent replacement of equipment components. The height of the receiving frame can be adjusted using a cylinder to accommodate workpieces with varying inner diameters. Furthermore, the adjustable motor can flexibly adjust the workpiece speed via a differential to meet different grinding requirements. The drive motor synchronously drives multiple transmission components through a single power source, reducing the complexity and energy consumption of multi-motor drives and lowering equipment operating costs. The workpiece fixing, grinding position adjustment, grinding, and part removal processes are seamlessly integrated, requiring minimal manual intervention. This not only reduces the labor intensity of operators but also shortens the single processing cycle, making it particularly suitable for batch production scenarios and effectively improving the overall production efficiency of water distributor processing.

[0024] 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.

[0025] Traditional grinding machines suffer from poor workpiece fixing mechanism stability. During grinding, the water distributor workpiece is prone to slight displacement or vibration, causing the grinding trajectory to deviate from the preset path. This not only fails to guarantee the consistency of the inner wall surface finish but may also generate machining defects such as scratches and steps on the inner wall of the workpiece. This embodiment provides an internal cylindrical grinding device for grinding machines that improves the surface finish of the water distributor's inner wall. Please refer to... Figures 1-4 The embodiment provides an internal grinding device for improving the smoothness of the inner wall of a water distributor. It includes a fixed frame 1, with a mounting plate 20 fixedly installed on the upper section of the fixed frame 1. A cylinder 3 is fixedly installed on the front of the mounting plate 20. A push rod 4 is fixedly connected to the bottom output end of the cylinder 3. A receiving frame 5 is fixedly connected to the bottom of the push rod 4. A drive motor 8 is fixedly installed on the top of the receiving frame 5. A drive wheel 9 is fixedly connected to the outer wall of the shaft fixedly connected to the bottom output end of the drive motor 8. A transmission wheel 11 and a transmission wheel 2 13 are connected to the outer wall of the drive wheel 9 via a transmission belt 10. A transmission shaft 12 is fixedly connected to the inner wall of the transmission wheel 11. A transmission rotating shaft 14 is fixedly connected to the inner wall of the transmission wheel 2 13. A connecting box 15 is fixedly installed on the lower outer wall of the receiving frame 5. The bottom outer wall of the transmission rotating shaft 14 is fixedly connected to... The device includes a grinding head 16, an adjusting motor 17 fixedly installed on the inner wall of the bottom of the fixed frame 1, a drive shaft 19 connected to the output end of the adjusting motor 17 via a differential 18, a gripper 21 fixedly installed on the top of the drive shaft 19, and a mounting plate 20 fixedly connected to the lower section of the fixed frame 1; a connecting slider 6 fixedly connected to the back of the receiving frame 5, and a fixed slide rail 7 slidably connected to the inner wall of the back of the connecting slider 6; the fixed slide rail 7 fixedly connected to the outer wall of the front of the fixed frame 1; a limiting slide opening is opened in the middle section of the receiving frame 5, and the lower section of the drive shaft 12 is located in the inner cavity of the limiting slide opening; a limiting slide opening is opened on the outer side of the receiving frame 5, and the outer wall of the upper section of the drive shaft 14 is located in the inner cavity of the limiting slide opening; the outer wall of the lower section of the drive shaft 14 is rotatably connected to the inner wall of the connecting box 15; and the gripper 21 is fixedly installed on the inner wall of the mounting plate 20.

[0026] Working principle: The operator places the water distributor workpiece to be processed on the mounting plate 20 at the bottom of the fixed frame 1. At this time, the gripper 21 fixedly installed on the inner wall of the mounting plate 20 is in the initial open state. After the device is started, the system first controls the operation of the regulating motor 17 fixedly installed on the inner wall of the bottom of the fixed frame 1. The power generated by the output of the regulating motor 17 is adjusted in speed and torque through the differential 18. The differential 18 transmits the adjusted power to the drive shaft 19, which drives the gripper 21 fixedly installed at the top to move. Under the drive of the drive shaft 19, the gripper 21 gradually retracts until it tightly clamps the outer wall of the water distributor workpiece, thus achieving a stable fixation of the water distributor workpiece. During this process, the differential 18 can ensure the stable speed of the drive shaft 19, avoiding the workpiece damage or insecure clamping caused by the gripper 21 clamping too fast or too slow. At the same time, the mounting plate 20 provides a stable mounting base for the gripper 21, ensuring that the gripper 21 will not shift position during the clamping process, providing stable workpiece support for subsequent grinding.

[0027] After the workpiece is fixed, the system controls the cylinder 3 fixedly mounted on the front of the mounting plate 20 fixedly installed on the upper section of the fixed frame 1. The cylinder 3, acting as a power source, pushes the push rod 4 fixedly connected to it downwards from its bottom output end. The push rod 4 transmits the thrust of the cylinder 3 to the receiving frame 5 fixedly connected at the bottom, causing the receiving frame 5 to move downwards as a whole. During the downward movement of the receiving frame 5, the connecting slider 6 fixedly connected to the back of the receiving frame 5 slides along the fixed slide rail 7 fixedly connected to the outer wall of the front of the fixed frame 1. The fixed slide rail 7 restricts and guides the movement direction of the connecting slider 6, thereby ensuring the smooth movement of the receiving frame. The frame 5 always moves smoothly in the vertical direction, avoiding left and right deviation or swaying during the movement; through the coordinated action of the cylinder 3, push rod 4, connecting slider 6 and fixed slide rail 7, the height position of the receiving frame 5 can be precisely adjusted, thereby driving the grinding components installed on the receiving frame 5, including drive motor 8, drive wheel 9, transmission belt 10, transmission wheel one 11, transmission shaft 12, transmission wheel two 13, transmission shaft 14, connecting box 15 and grinding head 16, to move downward until the grinding head 16 enters the inner cavity of the water distributor workpiece and is adjusted to the appropriate initial grinding position;

[0028] Once the grinding assembly is adjusted to the preset position, the system starts the drive motor 8 fixedly installed on the top of the support frame 5. The rotational power generated by the output end of the drive motor 8 drives the drive wheel 9 fixedly connected to the outer wall of the shaft at its bottom output end to rotate. The drive wheel 9 transmits the rotational power synchronously to the first drive wheel 11 and the second drive wheel 13 through the transmission belt 10 wrapped around its outer wall. At this time, the transmission belt 10 is in a taut state to ensure the stability and efficiency of power transmission and to avoid slippage.

[0029] Driven by the transmission belt 10, the first transmission wheel 11 rotates. Since the transmission shaft 12 is fixedly connected to the inner wall of the first transmission wheel 11, the first transmission wheel 11 drives the transmission shaft 12 to rotate synchronously. At the same time, a limiting slide is opened in the middle section of the receiving frame 5, and the lower section of the transmission shaft 12 is set in the inner cavity of the limiting slide. The limiting slide restricts and guides the rotation of the transmission shaft 12, preventing the transmission shaft 12 from radially deviating during rotation, ensuring that the rotation axis of the transmission shaft 12 remains stable, and providing auxiliary support for the stable operation of the second transmission wheel 13 and the transmission shaft 14.

[0030] Driven by the transmission belt 10, the second transmission wheel 13 rotates, and the transmission shaft 14, which is fixedly connected to the inner wall of the second transmission wheel 13, rotates synchronously with the second transmission wheel 13. A limiting slide is opened on the outer side of the receiving frame 5, and the upper section of the outer wall of the transmission shaft 14 is set in the inner cavity of the limiting slide. The limiting slide works in conjunction with the limiting slide in the middle section of the receiving frame 5 to further limit the radial displacement of the transmission shaft 14 and ensure the rotational stability of the transmission shaft 14. At the same time, the lower section of the outer wall of the transmission shaft 14 is rotatably connected to the inner wall of the connecting box 15, which is fixedly installed on the lower section of the outer wall of the receiving frame 5. The connecting box 15 provides an additional support point for the transmission shaft 14, effectively reducing the vibration of the transmission shaft 14 during high-speed rotation and ensuring that the transmission shaft 14 can stably transmit the rotational power to the grinding head 16 fixedly connected to the bottom outer wall.

[0031] The grinding head 16 rotates at high speed under the drive of the transmission shaft 14. At this time, the system can adjust the height position of the receiving frame 5 and the grinding head 16 by controlling the operation of the cylinder 3 and finely adjusting the extension and retraction of the push rod 4 according to the grinding requirements of the inner wall of the water distributor, so as to achieve grinding processing of different height positions of the inner circle of the water distributor. During the grinding process, the adjusting motor 17 can drive the chuck 21 and the workpiece of the water distributor to rotate slowly through the differential 18 and the drive shaft 19, so that all parts of the inner circle of the water distributor can be evenly contacted with the high-speed rotating grinding head 16, thereby ensuring the grinding uniformity of the inner wall of the water distributor and effectively improving the surface finish of the inner wall.

[0032] Once the grinding of the inner wall of the water distributor reaches the preset requirements, the system first controls the drive motor 8 to stop running, and the grinding head 16 to stop rotating; then it controls the cylinder 3 to run in reverse, the push rod 4 to retract, and drives the receiving frame 5 and the grinding head 16 to move upward and exit the inner cavity of the water distributor workpiece; finally, it controls the regulating motor 17 to run in reverse, and drives the gripper 21 to open through the differential 18 and the drive shaft 19, so that the operator can remove the processed water distributor workpiece and complete the entire grinding process.
