DETAILED DESCRIPTION

[0016] The following will be combined with the drawings Figures 1-3 The application will be further described in detail.

[0017] The application embodiment discloses a batch head sleeve grinding processing device. Figures 1-3 A batch head sleeve grinding processing device mainly consists of a rack 1, a moving assembly 2, an XY positioning platform 3, a processing knife 4, a positioning structure 5 and a driving device 6, realizing high-precision and high-efficiency grinding processing of the batch head sleeve, meeting the processing needs of batch head sleeves of different models, improving the processing quality and precision, and at the same time, having good stability and operation convenience.

[0018] Refer to Figure 1, the rack 1 as the foundation support structure of the whole device, made of high-strength cast iron or steel, which ensures that it has enough strength and stiffness, can withstand the cutting force and vibration generated in the grinding process, provides a stable installation platform for each component, ensures the smooth progress of the machining process, reduces the machining error caused by the deformation or shaking of the rack, improves the machining precision and the stability of the product quality. Its structure design is carefully optimized, fully considering the overall layout of the equipment, facilitating the accurate and secure installation of each component on it, while also facilitating the operation, debugging and maintenance of the operator, improving the ease of use and maintainability of the equipment, reducing the use cost and downtime of the equipment.

[0019] Referring to Figure 2 , the slide rail 201 in the moving assembly 2 adopts high-precision linear guide rails, and the matching precision between the slide block and the slide rail is extremely high. This high-precision matching enables the slide table 203 to slide smoothly and accurately on the slide rail 201, greatly reducing the friction resistance and gap during movement, thereby effectively improving the precision of position control and providing a basic guarantee for the accurate movement of the XY positioning platform 3 and the machining tool 4. The threaded rod 202 is made of high-strength alloy steel, and its thread precision meets the strict requirements of precision transmission and tightly matches the threaded hole on the slide table 203. By rotating the threaded rod 202, the rotary motion can be accurately converted into linear motion of the slide table 203, realizing the coarse adjustment function of the XY positioning platform 3 and the machining tool 4, ensuring that the machining tool 4 can quickly and accurately approach the workpiece, improving the machining efficiency and precision.

[0020] Referring to Figure 1 , the XY positioning platform 3 uses advanced numerical control positioning technology, and the internal motor uses a high-precision servo motor. This motor can accurately control the rotation angle and speed according to the precise instructions of the control system. The rotary motion of the motor is efficiently converted into linear motion of the platform in the X and Y directions through the screw-nut pair. The precision grade of the screw and nut and the matching precision of the guide rail and slide block are strictly controlled, so that the platform can achieve precise positioning within a small displacement range, meeting the precise control requirements of the machining tool 4 position for high-precision grinding of the bushing sleeve, ensuring that the machining tool 4 can accurately grind each part of the bushing sleeve in the X and Y planes, ensuring the uniformity and consistency of the machining, improving the machining quality and precision of the product, and meeting the machining needs of precision parts for high-end manufacturing.

[0021] Referring to Figure 1, the machining tool 4 is carefully selected according to the material of the tool sleeve, the machining precision and the surface quality requirements, for example, for different hardness and toughness of the tool sleeve material, the appropriate particle size, hardness and binder of the grinding wheel are selected to ensure that the tool can efficiently remove material during the grinding process, while ensuring the quality and precision of the machined surface. The installation of the tool is firm and reliable, professional clamping device and fixing method are adopted to ensure that there is no loosening or displacement during high-speed rotation and strong grinding process, and it is convenient to replace and adjust. The operator can quickly and accurately replace the tool according to the wear condition of the tool and the machining requirement, ensure the continuity and stability of the machining process, and improve the production efficiency.

[0022] With reference to Figure 3, positioning structure 5 is the key part to ensure the machining accuracy of the ball head sleeve. The chuck body 501 is made of high-quality metal material, which has sufficient structural strength and can withstand the clamping force of the ball head sleeve and the cutting force in the grinding process, ensuring that it will not deform or damage during machining, and ensuring the stability and accuracy of the machining. The machining accuracy of the guide groove is high, which provides an accurate moving track for the movable jaw 503, so that the movable jaw 503 can move smoothly in it, and can uniformly adjust the position according to the rotation of the flat threaded disc 502 when clamping the ball head sleeve, providing stable and uniform clamping force, preventing the ball head sleeve from moving or shaking during machining, and ensuring the accuracy and surface quality of the machining. The flat threaded disc 502 is precisely threaded, and the threads of the movable jaw 503 are well matched. When the flat threaded disc 502 is rotated, it can accurately drive the movable jaw 503 to move along the expected trajectory through the screw transmission principle, realize reliable clamping of the ball head sleeve, ensure that the center of the ball head sleeve coincides with the center of the positioning column 504, and improve the concentricity and accuracy of the machining. The number and distribution of the movable jaw 503 are reasonably designed according to the size range and clamping stability requirements of the ball head sleeve. Generally, three or four movable jaws 503 are evenly distributed on the circumference of the chuck body 501. This distribution method can uniformly apply clamping force from multiple directions to ensure the clamping stability of the ball head sleeve. The part of the movable jaw 503 that contacts the ball head sleeve is treated with wear-resistant and anti-skid materials, such as hard alloy inserts or surface quenching treatment, which can improve the reliability of clamping, prevent the ball head sleeve from slipping during machining, and protect the surface of the ball head sleeve from damage, ensuring the appearance quality and dimensional accuracy of the product. The positioning column 504 is designed and manufactured in series according to the inner hole size of different types of ball head sleeves, with high dimensional accuracy and surface roughness requirements, ensuring tight fit with the inner hole of the ball head sleeve, achieving accurate positioning of the inner hole, and the material of the positioning column 504 has certain hardness and wear resistance, which can withstand multiple insertion and friction during machining, ensuring its service life and positioning accuracy. The positioning column 504 and the chuck body 501 are connected by a detachable threaded connection, and are equipped with corresponding locking devices, which can be quickly replaced by the operator according to different types of ball head sleeves, and can ensure that the positioning column 504 will not loosen or fall off during machining, ensuring the stability and accuracy of the machining.

[0023] Referring to Figure 1, the driving device 6 selects the appropriate power and model according to the speed and torque requirements of the main shaft on the rack 1, and is firmly and reliably installed, and the connection with the main shaft adopts a high-precision shaft coupling or other reliable transmission connection mode, to ensure the stability and efficiency of power transmission, avoid vibration, impact or energy loss during power transmission, and ensure that the head sleeve can rotate at a stable speed to provide uniform cutting conditions for the grinding of the machining tool 4, improve the machining quality and surface finish. At the same time, the driving device 6 is effectively protected and damped to reduce the influence of vibration and noise on the machining precision and equipment life during operation, creating a stable and quiet machining environment that is conducive to precise operation and monitoring by the operator, improving production efficiency and product quality.

[0024] The implementation principle of the head sleeve grinding device according to an embodiment of the present application is as follows:

[0025] In the head sleeve processing workshop, the device is installed on a stable workbench to ensure that the rack 1 is in a horizontal state to avoid affecting the machining precision due to the inclination of the equipment.

[0026] The operator selects the appropriate type of positioning column 504 from the standby positioning column 504 according to the production task sheet or the actual size information of the head sleeve, and accurately installs it at the center position of the chuck body 501. The installation method can adopt threaded connection, plug-in connection or other reliable connection methods to ensure that the positioning column 504 does not shift or loosen during processing.

[0027] The head sleeve to be processed is sleeved on the installed positioning column 504, at which time the inner hole of the head sleeve is tightly matched with the positioning column 504 to realize internal positioning. Then, the operator uses a tool to rotate the flat threaded disc 502, and the threads of the flat threaded disc 502 are matched with the threads on the movable clamping jaw 503. With the rotation of the flat threaded disc 502, the movable clamping jaw 503 moves along the radial direction to the outer wall of the head sleeve under the limitation of the guide groove, until it is in close contact with the outer wall, thereby realizing the external clamping of the head sleeve. Through this internal and external positioning and clamping method, any form of displacement or shaking of the head sleeve during grinding can be effectively prevented, greatly improving the clamping precision and laying a solid foundation for subsequent high-precision grinding processing.

[0028] After the chuck sleeve is clamped and fixed, the operator inputs the cutting position parameters of the machining tool 4 in the X-axis and Y-axis directions according to the processing process requirements of the chuck sleeve in the control system. The control system transmits these parameters to the XY positioning platform 3, and the XY positioning platform 3 accurately drives the machining tool 4 to move to the set position in the X-axis and Y-axis planes through internal motors, screw nut pairs, guide rail sliders and other precise transmission components. At the same time, the driving device 6 is started, which can be a motor, a hydraulic motor or other suitable power source, and power is transmitted to the main shaft on the rack 1 through belt transmission, shaft coupling transmission or gear transmission, so that the main shaft drives the chuck sleeve to rotate at high speed. At this time, the machining tool 4 grinds the rotating chuck sleeve at the set position, and gradually grinds the chuck section of the chuck sleeve to the required size and shape according to the preset machining path and process parameters.

[0029] When a batch of chuck sleeves is processed, and different models of chuck sleeves need to be replaced, the operator only needs to stop the operation of the driving device 6 and other related devices, then disassemble the current positioning column 504, reinstall the positioning column 504 of the appropriate model according to the above steps, and clamp and fix the new chuck sleeve, so that the next batch of processing can be quickly started. The whole process is simple and efficient to operate, greatly improves the production efficiency, reduces the production cost, and can ensure that different batches and different models of chuck sleeves can obtain high-quality processing effect.
