Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a pressure regulating device for a surface grinding machine. Background Technology

[0002] In the field of precision manufacturing, surface grinding machines are key equipment for achieving high-precision planar machining of parts, and their performance directly affects the quality of parts and production efficiency. With the continuous improvement of manufacturing requirements for part precision, pressure regulation technology for surface grinding machines has become a research focus.

[0003] Traditional surface grinding machines have significant shortcomings in pressure regulation. Firstly, their pressure regulation precision is low, making it difficult to accurately control the pressure according to the characteristics of different parts and grinding requirements. This results in unstable grinding quality and a high defect rate. For example, when grinding some pressure-sensitive precision parts, the inability to adjust the pressure can easily cause surface damage or uneven grinding. Furthermore, the part positioning and fixing methods of traditional surface grinding machines are not precise or flexible enough, allowing parts to easily shift during the grinding process, further reducing grinding accuracy. Utility Model Content

[0004] The purpose of this invention is to provide a pressure regulating device for a surface grinder, so as to solve the problem mentioned in the background art that the pressure of existing surface grinders cannot be regulated.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The pressure regulating device of the surface grinding machine includes a grinding worktable, a surface grinding turntable is mounted on the grinding worktable, a part positioning ring seat is placed on the surface grinding turntable, and a side seat is mounted on the outer wall of the grinding worktable;

[0007] The top surface of the grinding workbench is provided with a groove, and the flat grinding turntable is embedded in the groove; a column is installed on the bottom edge of the groove, and an arc-shaped positioning arm for fixing the position of the part positioning ring seat is installed on the column.

[0008] A support column is installed on the top surface of the side seat, and a servo telescopic cylinder is vertically installed on the top surface of the support column. A servo hydraulic cylinder is vertically installed at the end of the piston rod of the servo telescopic cylinder, and a pressure plate that matches the inner diameter of the part positioning ring seat is coaxially installed at the bottom of the hydraulic rod of the servo hydraulic cylinder.

[0009] Preferably, a servo motor for driving the surface grinding turntable to rotate is embedded in the center of the top surface of the groove, enabling the surface grinding turntable to obtain precise and flexibly adjustable rotational power. The servo motor has high-precision speed and position control capabilities, and can accurately adjust the speed and direction of the surface grinding turntable according to the grinding requirements of different parts, thereby achieving a uniform and efficient grinding effect, effectively improving the grinding quality and production efficiency of parts, and meeting the requirements of diverse parts processing.

[0010] Preferably, both the column and the arc-shaped positioning arm are equipped with rotating wheels at their ends, and the part positioning ring seat is rotatably connected to the rotating wheels, which greatly improves the convenience of adjusting the position of the part positioning ring seat. When placing and removing parts, the part positioning ring seat can be easily rotated, facilitating operation. At the same time, it ensures that the part can rotate stably with the rotation of the flat grinding disc during the grinding process, reducing part displacement caused by friction and improving the stability and accuracy of the grinding process.

[0011] Preferably, the surfaces of the rollers at the ends of the column and the arc-shaped positioning arm are provided with wear-resistant rubber sleeves with a thickness of 1-3mm. On the one hand, the wear-resistant rubber sleeves have good wear resistance, which can extend the service life of the rollers and reduce the maintenance cost of the equipment; on the other hand, they can play a role in buffering and shock absorption, reducing the vibration and noise generated during the rotation of the part positioning ring seat, making the grinding process more stable, and further ensuring the grinding quality of the parts.

[0012] Preferably, the top surface of the pressure plate is coaxially connected to a plug-in post that engages with the bottom of the hydraulic rod, making the connection and disassembly between the pressure plate and the hydraulic rod simpler and faster. When it is necessary to replace the pressure plate with one of different specifications for different parts, the operation can be completed quickly, improving the adaptability and maintenance efficiency of the equipment, reducing downtime, and ensuring production continuity.

[0013] Preferably, the outer wall of the insertion post is provided with positioning screw holes, providing a reliable positioning point for fixing the pressure plate and the hydraulic rod. In conjunction with subsequent fixing bolts, the connection position between the insertion post and the hydraulic rod can be ensured to be accurate, enhancing the stability and reliability of the connection, preventing the pressure plate from loosening or shifting during the grinding process, and guaranteeing the accuracy of pressure transmission.

[0014] Preferably, the outer wall of the hydraulic rod is fitted with a threaded fixing bolt that matches the size of the positioning screw hole, further strengthening the connection between the plug-in column and the hydraulic rod. The threaded connection can withstand greater pressure and torque, effectively preventing loosening of the connection due to pressure changes or equipment vibration during grinding. This ensures that the pressure plate can stably apply pressure to the parts, thereby guaranteeing the stability of the grinding process and the accuracy of pressure regulation.

[0015] Compared with existing technologies, the advantages of this utility model are as follows: In the pressure regulating device of this surface grinding machine, the grinding worktable and the groove on its top surface allow the surface grinding turntable to be accurately and stably embedded in the groove, providing a stable and reliable base platform for the entire surface grinding process. With the help of the column installed at the bottom edge of the groove and the arc-shaped positioning arm installed on the column for fixing the position of the part positioning ring seat, the part positioning ring seat can be accurately positioned and fixed, ensuring that the part maintains the correct position throughout the grinding process, greatly improving the positioning accuracy of the part grinding and ensuring the consistency of the quality of the ground parts. The side seat is configured as a support column to provide an installation base, and the support column installed on the top surface of the side seat provides stable support for the servo telescopic cylinder, enabling the servo telescopic cylinder to work stably. The servo hydraulic cylinder vertically installed at the piston rod end of the servo telescopic cylinder can achieve precise control and adjustment of pressure. The pressure plate, which is coaxially mounted at the bottom of the hydraulic rod of the servo hydraulic cylinder and is adapted to the inner diameter of the part positioning ring seat, can evenly apply pressure to the part, avoiding damage caused by concentrated pressure. At the same time, the pressure can be flexibly adjusted according to the needs of different parts, improving the applicability of the equipment and the grinding effect, realizing efficient, precise and stable surface grinding operations, and improving production efficiency and product quality.

Therefore, they should not be construed as limitations on this utility model.

[0027] The pressure regulating device of a surface grinder, such as Figures 1-3As shown, the system includes a grinding table 10, on which a flat grinding turntable 20 is mounted. A part positioning ring seat 30 is placed on the flat grinding turntable 20. A side seat 40 is mounted on the outer wall of the grinding table 10. A groove 11 is formed on the top surface of the grinding table 10, and the flat grinding turntable 20 is embedded in the groove 11. A column 12 is mounted on the bottom edge of the groove 11, and an arc-shaped positioning arm 13 for fixing the position of the part positioning ring seat 30 is mounted on the column 12. A support column 41 is mounted on the top surface of the side seat 40, and a servo telescopic cylinder 50 is vertically mounted on the top surface of the support column 41. A servo hydraulic cylinder 52 is vertically mounted on the end of the piston rod 51 of the servo telescopic cylinder 50. A pressure plate 54, matching the inner diameter of the part positioning ring seat 30, is coaxially mounted at the bottom of the hydraulic rod 53 of component 2. Through the grinding worktable 10 and its top surface groove 11, the surface grinding turntable 20 can be precisely and securely embedded in the groove 11, providing a stable and reliable base platform for the entire surface grinding process. With the help of the column 12 mounted on the bottom edge of the groove 11 and the arc-shaped positioning arm 13 mounted on the column 12 for fixing the position of the part positioning ring seat 30, the part positioning ring seat 30 can be precisely positioned and fixed, ensuring that the part maintains the correct position throughout the grinding process, greatly improving the positioning accuracy of the part grinding and ensuring the consistency of the part's quality after grinding. The side seat 40 is configured to provide a mounting base for the support column 41. The support column 41 mounted on the top surface of the side seat 40 provides stable support for the servo telescopic cylinder 50, enabling the servo telescopic cylinder 50 to work stably. A servo hydraulic cylinder 52 is vertically mounted at the end of the piston rod 51 of the servo telescopic cylinder 50, enabling precise control and adjustment of pressure. The pressure plate 54, which is coaxially mounted at the bottom of the hydraulic rod 53 of the servo hydraulic cylinder 52 and is adapted to the inner diameter of the part positioning ring seat 30, can evenly apply pressure to the part, avoiding damage to the part caused by pressure concentration. At the same time, the pressure can be flexibly adjusted according to the needs of different parts, improving the applicability of the equipment and the grinding effect, realizing efficient, accurate and stable surface grinding operation, and improving production efficiency and product quality.

[0028] Furthermore, a servo motor for driving the surface grinding turntable 20 to rotate is embedded in the center of the top surface of the groove 11, enabling the surface grinding turntable 20 to obtain precise and stable rotational power. The servo motor has the advantages of high control precision and fast response speed, and can accurately adjust the speed and direction of the surface grinding turntable 20 according to different grinding requirements, thereby achieving efficient and uniform grinding of parts, effectively improving grinding quality and production efficiency.

[0029] Specifically, both the column 12 and the arc-shaped positioning arm 13 are equipped with rotating wheels 14 at their ends. The part positioning ring seat 30 is rotatably connected to the rotating wheels 14. The surfaces of the rotating wheels 14 at the ends of the column 12 and the arc-shaped positioning arm 13 are covered with wear-resistant rubber sleeves with a thickness of 1-3mm, allowing the part positioning ring seat 30 to rotate more smoothly while remaining in a fixed position. The wear-resistant rubber sleeves not only reduce friction and wear between the rotating wheels 14 and the part positioning ring seat 30, extending the service life of the equipment, but also provide a certain buffering effect, reducing vibration and noise generated during rotation, further ensuring the stability and precision of the grinding process.

[0030] The pressure plate 54 has a coaxially connected insertion post 56 on its top surface center, which engages with the bottom of the hydraulic rod 53, making the connection between the pressure plate 54 and the hydraulic rod 53 more convenient and stable. The insertion method facilitates the installation and removal of the pressure plate 54. When the pressure plate 54 wears out or needs to be replaced with a different specification pressure plate, the replacement operation can be completed quickly, improving the maintenance efficiency and applicability of the equipment.

[0031] Furthermore, a positioning screw hole 57 is provided on the outer wall of the plug-in post 56, and a fixing bolt 55, which is compatible with the size of the positioning screw hole 57 and is threadedly connected, is installed on the outer wall of the hydraulic rod 53, making the connection between the plug-in post 56 and the hydraulic rod 53 more secure and reliable. The threaded connection between the fixing bolt 55 and the positioning screw hole 57 can effectively prevent the pressure plate 54 from loosening or falling off during operation, ensuring the stability and accuracy of pressure transmission, thereby ensuring the precision of pressure adjustment for the parts during the grinding process.

[0032] Working principle of the pressure regulating device of this surface grinder:

[0033] First, place the part to be ground inside the part positioning ring seat 30. With the help of the rotating wheel 14 at the end of the arc-shaped positioning arm 13 installed on the column 12, easily rotate the part positioning ring seat 30 and adjust the part to a suitable position. The wear-resistant rubber sleeve on the surface of the rotating wheel 14 can reduce friction and vibration.

[0034] Next, the servo motor embedded in the center of the top surface of the groove 11 is started, which drives the flat grinding turntable 20 to rotate, providing basic power for grinding;

[0035] Then, the servo telescopic cylinder 50 on the top support column 41 of the control seat 40 is made to extend its piston rod 51, which drives the servo hydraulic cylinder 52 to move to the appropriate position; then the servo hydraulic cylinder 52 is started, the hydraulic rod 53 is extended, and the pressure plate 54, which is connected to the hydraulic rod 53 through the plug-in column 56, is lowered accordingly. When the pressure plate 54 approaches the part, the pressure value of the servo hydraulic cylinder 52 is adjusted according to the pressure required for grinding the part, so that the pressure plate 54 applies appropriate pressure to the part.

[0036] During the grinding process, the pressure can be observed in real time and adjusted as needed. After grinding is completed, the servo hydraulic cylinder 52 is controlled to retract the hydraulic rod 53 and raise the pressure plate 54. Then, the relevant components are moved away by the servo telescopic cylinder 50 to remove the ground parts.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
