Description

Technical Field

[0001] This utility model relates to the field of guide sleeve grinding technology, and in particular to a guide sleeve precision grinding mechanism. Background Technology

[0002] A guide bushing precision grinding mechanism is a specialized grinding equipment or process system used for high-precision machining of guide bushings (usually mechanical guiding elements). It is mainly used to ensure the dimensional accuracy, shape accuracy, and surface finish of key parts such as the inner and outer circles and end faces of the guide bushing.

[0003] Existing precision grinding mechanisms for guide bushings lack a multi-directional movement structure for the grinding fluid nozzle. This leads to a significant waste of grinding fluid when spraying it over a large area to ensure lubrication. Because the nozzle position is fixed, the spray range cannot be flexibly adjusted according to the size of the guide bushing and the grinding area. This not only increases the amount of grinding fluid used but may also cause uneven cooling of the processing area, affecting processing accuracy and surface quality. Furthermore, it increases waste fluid treatment costs and the risk of pollution to the working environment.

[0004] Therefore, to address the problem that the existing guide sleeve precision grinding mechanism does not have a multi-directional movement structure for the grinding fluid nozzle, which leads to a large-area spraying method and significant waste of grinding fluid when spraying grinding fluid to ensure lubrication, a new guide sleeve precision grinding mechanism can be designed. Utility Model Content

[0005] To overcome the problem that existing guide sleeve precision grinding mechanisms do not have a multi-directional movement structure for the grinding fluid nozzle, which leads to a large-area spraying method when spraying grinding fluid to ensure lubrication, resulting in significant waste of grinding fluid.

[0006] The technical solution of this utility model is as follows: a guide sleeve precision grinding mechanism, including a grinding machine body, a mounting frame and a lead screw. The mounting frame is set on the top right side of the grinding machine body. A reducer is installed on the rear side of the mounting frame. A drive motor is connected to the right side of the reducer. The lead screw is rotatably connected to the front and rear ends inside the mounting frame. The drive motor is used to drive the reducer to rotate the lead screw. A movable seat is threaded through the outer surface of the lead screw. A protective shell is installed on the left side of the movable seat. A cylinder is installed on the top of the protective shell. A slider is connected to the output end of the cylinder. The cylinder is used to push the slider to slide up and down. A connecting rod is connected to the bottom of the slider. The bottom of the connecting rod is engaged with the grinding fluid nozzle.

[0007] Preferably, by setting a drive motor, the lead screw can be driven to rotate during operation through the reversing and deceleration effect of the reducer. When the lead screw rotates, it can drive the moving seat that is threaded with it to move left and right. When the cylinder is in operation, it can push the slider to drive the connecting rod to move up and down, thereby realizing multi-directional movement adjustment of the grinding fluid nozzle. This allows the grinding fluid to be accurately sprayed on the outer surface of the guide sleeve, reducing the amount of grinding fluid used while maintaining the lubrication effect. This solves the problem that the existing guide sleeve precision grinding mechanism does not have a multi-directional movement structure for the grinding fluid nozzle, which leads to a large-area spraying method when spraying grinding fluid to ensure the lubrication effect, resulting in serious waste of grinding fluid.

[0008] Preferably, two symmetrical first guide rails are installed on the left side of the mounting frame, and the slide block is slidably connected to the first guide rails.

[0009] Preferably, two symmetrical second guide rails are installed on the inner right side of the protective shell, and the slider is slidably connected to the second guide rails.

[0010] Preferably, a positioning plate is installed on the upper side of the base of the grinding machine body between the two grinding rollers, and a positioning component is provided on the top of the positioning plate.

[0011] Preferably, the positioning component includes a mounting base, a connecting shaft, and a positioning claw; the upper side of the positioning plate is provided with a mounting base, and two connecting shafts are rotatably connected to both the front and rear ends of the mounting base, with a positioning claw fixed to the outer side of each connecting shaft.

[0012] Preferably, the positioning assembly also includes pins and tension springs; pins are inserted into the outer sides of the four positioning claws, and tension springs are connected between the corresponding two pins to drive the positioning claws to reset.

[0013] Preferably, a protective plate is provided on the left side of the protective shell, and several fixing screws are provided on the left side of the protective plate. The protective plate is fixed to the protective shell by the fixing screws.

[0014] The beneficial effects of this utility model are:

[0015] By installing the grinding fluid nozzle with a multi-directional movable linkage, the spray position can be flexibly adjusted, ensuring precise coverage of the outer surface of the guide sleeve with grinding fluid. This significantly reduces splashing and waste. This design not only optimizes lubrication, ensuring continuous cooling and lubrication of the grinding area, but also reduces grinding fluid consumption, balancing environmental protection and cost-effectiveness. At the same time, precise spraying avoids liquid residue caused by traditional flooding methods, further improving the cleanliness of the machined surface, extending the service life of tools and equipment, and achieving a dual improvement in high efficiency, energy saving, and processing quality.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6 This utility model provides an embodiment of a guide sleeve precision grinding mechanism, including a grinding machine body 1, a mounting frame 2, and a lead screw 5. The mounting frame 2 is located on the top right side of the grinding machine body 1. A reducer 3 is mounted on the rear side of the mounting frame 2. A drive motor 4 is connected to the right side of the reducer 3. The lead screw 5 is rotatably connected to the front and rear ends inside the mounting frame 2. The drive motor 4 drives the reducer 3 to rotate the lead screw 5. A movable seat 6 is threaded through the outer surface of the lead screw 5. A protective shell 8 is mounted on the left side of the movable seat 6. A cylinder 9 is mounted on the top of the protective shell 8. A slider is connected to the output end of the cylinder 9. 10. Cylinder 9 is used to push slider 10 to slide up and down. The bottom of slider 10 is connected to connecting rod 11. The bottom of connecting rod 11 is engaged with grinding fluid nozzle. Power is provided by drive motor 4. The reducer 3 realizes the reversing and deceleration functions, driving lead screw 5 to rotate. The rotating lead screw 5 is converted into the lateral displacement of moving seat 6 through threaded engagement with moving seat 6. At the same time, cylinder 9 drives slider 10 to make linear motion, realizing precise positioning and adjustment of grinding fluid nozzle, ensuring that grinding fluid can accurately cover the outer surface of guide sleeve. This design significantly improves the utilization efficiency of grinding fluid while ensuring effective lubrication.

[0025] Please see Figures 2-4 In this embodiment, two vertically symmetrical first guide rails 12 are installed on the left side of the mounting frame 2. The slide block 7 is slidably connected to the first guide rails 12. By setting the first guide rails 12, the movement direction of the slide block 7 can be restricted, thereby improving the stability of the slide block 7 during movement. Two front-to-back symmetrical second guide rails 13 are installed on the right side inside the protective shell 8. The slider 10 is slidably connected to the second guide rails 13. By setting the second guide rails 13, the movement direction of the slider 10 can be restricted, thereby improving the stability of the slider 10 during movement. A positioning plate 14 is installed on the upper side of the base of the grinding machine body 1 between the two grinding rollers. A positioning component is provided on the top of the positioning plate 14. By setting the positioning plate 14, the positioning component can be installed.

[0026] Please see Figure 1 , Figure 2 , Figure 5 and Figure 6 In this embodiment, the positioning assembly includes a mounting base 151, connecting shafts 152, and positioning claws 153. A mounting base 151 is provided on the upper side of the positioning plate 14. Two connecting shafts 152 are rotatably connected to both the front and rear ends of the mounting base 151. A positioning claw 153 is fixed to the outer side of each connecting shaft 152. By setting the positioning claws 153, the four positioning claws 153 can position the guide sleeve to be ground, improving its grinding accuracy. The positioning assembly also includes pins 154 and tension springs 155. Pins 154 are inserted into the outer sides of each of the four positioning claws 153, and a connection is made between corresponding two pins 154. The tension spring 155, which drives the positioning claw 153 to reset, is used to place the guide sleeve between the four positioning claws 153. The downward pressure on the positioning claws 153 forces the positioning claws 153 on both sides to open. The rebound force of the tension spring 155 acts in the opposite direction on the positioning claws 153, causing the four positioning claws 153 to rotate inward, thereby achieving the positioning of the guide sleeve. A protective plate 16 is provided on the left side of the protective shell 8. Several fixing screws 17 are provided on the left side of the protective plate 16. The protective plate 16 is fixed to the protective shell 8 by the fixing screws 17. By setting the protective plate 16, the slider 10 can be protected.

[0027] During operation, the drive motor 4 provides power, which is then reduced in direction by the reducer 3 to drive the lead screw 5 to rotate. The moving seat 6, driven by the threaded transmission of the lead screw 5, achieves precise left and right movement. At the same time, the cylinder 9 drives the slider 10 to move linearly along the second guide rail 13, and the connecting rod 11 drives the grinding fluid nozzle to adjust up and down. Combined with the guiding effect of the first guide rail 12 on the slide 7, the movement process is stable and reliable. When the guide sleeve is inserted, the downward pressure causes the positioning claw 153 to open outward, and then the rebound force of the tension spring 155 causes the positioning claw 153 to tighten inward, achieving precise positioning of the guide sleeve. In addition, the protective plate 16 effectively protects the moving parts of the slider 10. The entire device achieves precise spraying of grinding fluid through multi-directional coordinated adjustment, which improves processing stability while ensuring the grinding accuracy of the guide sleeve.

[0028] Through the above steps, the drive motor 4 is used as the power source. After reversing and decelerating through the reducer 3, it drives the lead screw 5 to rotate. The lead screw 5 and the moving seat 6 are connected by a thread to convert the rotational motion into linear motion, realizing the precise left and right displacement of the moving seat 6. At the same time, the cylinder 9 pushes the slider 10 to reciprocate, and through the connecting rod 11, it drives the grinding fluid nozzle to adjust up and down, thereby forming a multi-directional coordinated motion. This allows the grinding fluid to accurately cover the outer surface of the guide sleeve, ensuring sufficient lubrication while effectively reducing the amount of grinding fluid used, improving the cooling efficiency and economic benefits of the processing process. This solves the problem that the existing precision grinding mechanism for guide sleeves does not have a multi-directional movement structure for the grinding fluid nozzle, which leads to a large-area spraying method when spraying grinding fluid to ensure the lubrication effect, resulting in serious waste of grinding fluid.
