Description

Technical Field

[0001] This utility model relates to the technical field of grinding machine headstock components, specifically a grinding machine headstock component. Background Technology

[0002] The headstock assembly is a crucial component of a grinding machine. It is used to mount and clamp workpieces and to perform precision machining on them through rotational motion. Mounting a chuck on the headstock and using it in combination with the tailstock is a common clamping method on cylindrical grinding machines. The mounting precision of the headstock assembly affects the grinding quality of the workpiece.

[0003] For example, patent CN222269875U discloses a headstock component for a grinding machine, including a headstock body. The headstock body has a spindle cavity and a drive cavity inside. A spindle is rotatably mounted in the spindle cavity in the left-right direction. A front cover is located on the right side of the drive cavity. A spindle cover is connected to the right end of the spindle. A spindle cover ring is fitted around the spindle cover. A fixing cylinder is fitted around the portion of the spindle located in the drive cavity. The left side of the fixing cylinder is fixedly connected to the drive cavity. A spindle drive wheel is rotatably mounted on the fixing cylinder. A first keyway is formed on the right end surface of the spindle. A second keyway is formed on the spindle drive wheel corresponding to the first keyway. A flat key is provided between the first and second keyways. The headstock body also has a drive mechanism for driving the spindle drive wheel to rotate. This design is suitable not only for general workpieces with... The machining of traction devices or clamps is also applicable to the machining of some center hole end drives, which can simultaneously machine the two end faces of shaft parts or the outer diameter of the entire shaft. When using a combination of chuck and tailstock to clamp workpieces, the workpiece must first be placed on the chuck of the headstock and fixed by the clamping device of the chuck. Then, the other end of the workpiece is inserted into the center of the tailstock to ensure that it will not shift during rotation. The accuracy of the center height of the headstock and tailstock on the grinding machine affects the grinding quality of the workpiece. In actual operation, due to installation errors, wear, or improper adjustment, the center height of the headstock and tailstock may not be consistent with the height of the worktable, resulting in a hyperboloid surface on the ground workpiece, which affects the cylindricity and surface quality of the workpiece.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing grinding machine headstock components. Utility Model Content

[0026] 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.

[0027] Example 1: Please refer to Figures 1-7 This utility model provides the following technical solution: a grinding machine headstock component, including a mounting base 1 installed on the grinding machine, a drive housing 2 fixedly installed on the mounting base 1, a chuck 3 connected to the output of the drive housing 2, a drive slide 4 slidably installed on the grinding machine below the mounting base 1, a mounting bracket 5 fixedly installed on the upper end face of the drive slide 4, a limit strip 6 engaged on the mounting bracket 5, and the limit strip 6 fixedly installed at the bottom of the mounting base 1; the mounting bracket 5 is provided with an adjustment mechanism to adjust the installation height of the mounting base 1 to keep the center height of the headstock component and the tailstock component consistent; the drive slide 4 is also provided with a locking mechanism to limit the adjustment position of the mounting base 1.

[0028] The adjustment mechanism includes a lifting bracket 7 that is slidably mounted in the mounting bracket 5, and multiple cylindrical grooves 8 are equally spaced on the lifting bracket 7; multiple cylindrical rods 9 are fixedly mounted at equal intervals on the limit strip 6, and the cylindrical rods 9 move down and engage with the cylindrical grooves 8.

[0029] The mounting bracket 5 is rotatably connected to a longitudinal lead screw 71, and a longitudinal internal threaded bracket 72 is installed on the external thread of the longitudinal lead screw 71. The longitudinal internal threaded bracket 72 is fixedly installed on the lifting bracket 7.

[0030] When installing the headstock assembly on the grinding machine, firstly, the limiting clip 6 is engaged and installed on the outside of the mounting bracket 5. The cylindrical rod 9 on the limiting clip 6 is engaged and connected to the inside of the cylindrical groove 8 on the lifting bracket 7. The engagement connection structure initially limits the installation position of the limiting clip 6. Then, according to the center height of the tailstock installed on the grinding machine, the center height of the headstock is adjusted, and the longitudinal lead screw 71 is controlled to rotate. The longitudinal lead screw 71 controls the longitudinal internal thread frame 72 to move up and down through the threaded transmission. The longitudinal internal thread frame 72 drives the lifting bracket 7 to move longitudinally in sync. The lifting bracket 7 drives the limiting clip 6 and the mounting base 1 to move up and down through the engaged cylindrical groove 8 and cylindrical rod 9, thereby realizing the adjustment of the installation height of the headstock assembly, maintaining its installation accuracy, and ensuring that the center height of the headstock and tailstock are consistent so that the workpiece is accurately fixed on the grinding machine. The headstock and tailstock can be used to control the movement of the workpiece through dual drive.

[0031] Example 2: Please refer to Figures 1-9 Based on Embodiment 1, a locking mechanism is also disclosed, the specific structure of which is as follows: The locking mechanism includes a slide groove 10 formed on the drive slide 4, a slide column 11 slidably connected in the slide groove 10, and a vertical rod 12 fixedly installed on the upper end face of the slide column 11; a transverse lead screw 111 is rotatably connected on the drive slide 4, and the slide column 11 is threaded onto the outside of the transverse lead screw 111; a locking rod 13 is transversely slidably connected on the vertical rod 12, and a locking spring 14 is elastically connected between the locking rod 13 and the vertical rod 12.

[0032] The drive slide 4 is equipped with a power mechanism that switches between a control adjustment mechanism and a locking mechanism. The power mechanism includes a front rotating rod 15, a middle rotating rod 19, and a rear rotating rod 17 that are sequentially rotatably mounted on the drive slide 4 in the transverse direction. Both ends of the middle rotating rod 19 are connected to toothed shafts 20 along the axial direction. The toothed shafts 20 at both ends are respectively engaged with the front rotating rod 15 and the rear rotating rod 17. A drive rod 21 is fixedly connected to the end face of the toothed shaft 20 near the front rotating rod 15. The drive rod 21 passes through the front rotating rod 15.

[0033] The front rotating rod 15 is externally fixedly sleeved with a front driving bevel gear 16, and a front driven bevel gear 23 is meshed with the front driving bevel gear 16. The front driven bevel gear 23 is fixedly installed on the end face of the transverse lead screw 111. The rear rotating rod 17 is externally fixedly sleeved with a rear driving bevel gear 18, and a rear driven bevel gear 22 is meshed with the rear driving bevel gear 18. The rear driven bevel gear 22 is coaxially connected with the longitudinal lead screw 71.

[0034] After adjusting the installation height of the limit clip 6 and the mounting base 1, control the rotation of the transverse screw 111. Under the threaded transmission, the transverse screw 111 controls the slide column 11 to slide along the opening direction of the slide groove 10. The slide column 11 drives the upright 12 to move synchronously. The upright 12 drives the locking rod 13 to move close to the limit clip 6, so that the locking rod 13 is pressed against the side of the limit clip 6, locking the installation position of the limit clip 6 and the mounting base 1, and maintaining the stability of the head frame component installation.

[0035] When the drive rod 21 moves through the front rotating rod 15, it can switch between driving the longitudinal lead screw 71 and the transverse lead screw 111. The control method is as follows:

[0036] When it is necessary to control the rotation of the longitudinal lead screw 71, the drive rod 21 is pushed through the front rotating rod 15 and moved closer to the rear rotating rod 17. The drive rod 21 drives the toothed shaft 20 and the intermediate rotating rod 19 to move laterally synchronously. The intermediate rotating rod 19 is movably mounted on the drive slide 4 and can rotate and move laterally. The toothed shaft 20 on one side of the intermediate rotating rod 19 moves and engages with the rear rotating rod 17. At this time, the toothed shaft 20 on the other side of the intermediate rotating rod 19 moves and separates from the front rotating rod 15. At this time, rotating the drive rod 21 can drive the rear rotating rod 17 to rotate through the intermediate rotating rod 19 and the toothed shaft 20. The rear active bevel gear 18 fixed on the rear rotating rod 17 rotates synchronously. Under the meshing transmission of the rear active bevel gear 18 and the rear driven bevel gear 22, the longitudinal lead screw 71 can be driven to rotate, thereby achieving the purpose of driving the longitudinal lead screw 71 to rotate and adjusting the installation height of the mounting base 1.

[0037] When it is necessary to control the rotation of the transverse lead screw 111, the drive rod 21 is pushed through the front rotating rod 15 and moved away from the rear rotating rod 17. The drive rod 21 drives the toothed shaft 20 and the intermediate rotating rod 19 to move laterally, so that the toothed shaft 20 at one end of the intermediate rotating rod 19 moves and engages with the front rotating rod 15, and the toothed shaft 20 at the other end of the intermediate rotating rod 19 moves and separates from the rear rotating rod 17. At this time, the drive rod 21 is controlled to rotate. The drive rod 21 can drive the front rotating rod 15 to rotate synchronously through the toothed shaft 20. At this time, the front driving bevel gear 16 fixed outside the front rotating rod 15 rotates synchronously. The front driving bevel gear 16 meshes with the front driven bevel gear 23. Under the meshing transmission, it can drive the front driven bevel gear 23 and the transverse lead screw 111 to rotate. The rotation of the transverse lead screw 111 can drive the upright rod 12 and the locking rod 13 to move, thereby locking the installation position of the mounting base 1.
