Description

Technical Field

[0001] This invention relates to the technical field of ball head external cylindrical grinding, and in particular to an automatic ball head external cylindrical grinding device that can assist in the repair of grinding wheels. Background Technology

[0002] Precision grinding of the outer spherical surface of ball-end workpieces is an important process in the manufacturing of precision parts, and is widely used in the production and processing of various precision machinery, hydraulic components, and hardware components. Currently, most existing ball-end external cylindrical grinding equipment adopts a single-set fixed grinding structure, relying solely on a single grinding wheel to continuously complete the ball-end grinding operation, resulting in a relatively simple processing mode. In actual grinding production, cup-shaped grinding wheels are in long-term, high-speed contact with ball-shaped workpieces for generating grinding. This easily leads to problems such as contour wear and edge chipping on the wheel's working surface, resulting in decreased wheel sharpness and deviation in the spherical contour accuracy. This directly affects the surface roughness, roundness, and overall machining accuracy of the ball-shaped workpiece. To ensure product quality, traditional processing methods require frequent equipment shutdowns, manual disassembly of the grinding wheel, and the use of specialized equipment for shaping, cleaning, and repair. Only after the grinding wheel is repaired and re-clamped and adjusted can production continue. This shutdown and repair process not only significantly disrupts continuous production, shortening the effective processing time and reducing production efficiency, but also introduces clamping errors due to frequent disassembly and adjustment, further reducing workpiece machining consistency. Furthermore, existing grinding equipment cannot achieve simultaneous parallel operation of grinding and repair, resulting in poor process integration, low equipment utilization, and insufficient stability in batch production, making it difficult to meet the demands of high-precision, high-efficiency, large-scale ball-shaped workpiece machining. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic ball head outer diameter grinding device that can not only automatically grind the outer diameter of the ball head, but also assist in the repair of the grinding wheel.

[0004] The automatic ball head external cylindrical grinding equipment that can assist in the repair of grinding wheels provided by this invention adopts the following technical solution: Includes a base, the top of which is fixedly connected to a housing, and a grinding assembly is provided on the top of the base; The base is provided with a grinding wheel assembly at the top, a flipping assembly at the bottom, and a sealing assembly at the top. A repair component is provided on the top of the base, and a water spray component is provided on the outer shell; The grinding wheel assembly includes a support platform, a support plate is fixedly connected to the top of the support platform, a third motor is detachably connected to the outer wall of the support plate, a worm gear is fixedly connected to the output end of the third motor, a worm wheel is rotatably connected to the outer wall of the support plate, and a second pneumatic gripper is rotatably connected to the outer wall of the support plate, with a cup-shaped grinding wheel provided on the second pneumatic gripper. The repair assembly includes a fourth motor, the output end of which is fixedly connected to a lead screw. One end of the lead screw is rotatably connected to the top of the base. A drive plate is threaded onto the outer wall of the lead screw. A spring telescopic plate is fixedly connected to the side of the drive plate away from the fourth motor. A push ring is fixedly connected to the end of the spring telescopic plate away from the drive plate. The inner wall of the push ring is rotatably connected to the outer wall of the support platform. A fixing plate is fixedly connected to the top of the push ring. A repair knife is detachably connected to the fixing plate through a hole provided at the top.

[0005] Preferably, the grinding assembly includes a mounting plate, a first motor is fixedly connected to the outer wall of the mounting plate, a first pneumatic gripper is rotatably connected to the side of the mounting plate away from the first motor, an electric telescopic plate is fixedly connected to the side of the mounting plate away from the first motor, a positioning plate is detachably connected to the base via a linear motor provided at the top, a second motor is detachably connected to the top of the positioning plate, and the output end of the second motor is fixedly connected to one end of the electric telescopic plate.

[0006] By adopting the above technical solution, and by setting up a mounting plate, a first motor, a first pneumatic gripper, an electric telescopic plate, a second motor, and a positioning plate, the ball head can be clamped, rotated, and oscillated. The clamping can be adapted to different specifications of rods, avoiding axial movement of the workpiece during processing and ensuring the consistency of batch processing accuracy. The rotation can make all parts of the spherical surface participate in grinding evenly, eliminating uneven local wear and processing blind spots caused by single-point contact, and improving the roundness and contour consistency of the spherical surface. The oscillation can complete the grinding of the entire spherical surface of the ball head without dead angles, eliminating processing blind spots and improving the roundness and contour accuracy of the spherical surface.

[0007] Preferably, a support rod is fixedly connected to the bottom of the mounting plate, and a ball is provided at the bottom end of the support rod, with the outer wall of the ball fitting against the top of the base.

[0008] By adopting the above technical solution, the mounting plate is supported by a support rod and a ball bearing, thereby preventing the mounting plate from shaking when it drives the ball head to rotate, which would affect the stability of the ball head and thus avoid affecting the grinding accuracy of the ball head.

[0009] Preferably, the flipping assembly includes a rack, the top of which is fixedly connected to the bottom of the base, the support platform is rotatably connected to a gear via a rotating ring at the bottom, a circular block is fixedly connected to the bottom of the support platform, a first spring telescopic rod is fixedly connected to the circular block, and a locking block is fixedly connected to the telescopic end of the first spring telescopic rod.

[0010] By adopting the above technical solution, and by setting racks, gears, circular blocks, first spring telescopic rods and locking blocks, the support platform can be driven to rotate during reset, thereby allowing the two sets of cup-shaped grinding wheels to switch positions. This makes it convenient for workers to repair the cup-shaped grinding wheels that have already been ground on the ball head, thus avoiding affecting the overall efficiency of the device.

[0011] Preferably, a fixing strip is fixedly connected to the bottom of the gear, and a blocking strip is fixedly connected to the bottom of the base, with the side of the blocking strip near the gear being inclined.

[0012] By adopting the above technical solution, the locking block can be fixed by setting the fixing strip and the blocking strip. In this way, the round block and the support platform are fixed by fixing the locking block, thereby avoiding the shaking of the cup-shaped grinding wheel when grinding the ball head, which would affect the grinding accuracy of the ball head.

[0013] Preferably, the sealing assembly includes a mounting wheel, the inner ring of which is fixedly connected to the outer wall of the output end of the fourth motor, a steel wire rope is provided on the outer wall of the mounting wheel, a second spring telescopic rod is fixedly connected to the inner wall of the housing, a closing door is fixedly connected to the movable end of the second spring telescopic rod, and the bottom end of the steel wire rope is detachably connected to the top of the closing door.

[0014] By adopting the above technical solution, and by setting up mounting wheels, wire ropes, closed doors, and second spring telescopic rods, it is possible to prevent cooling water from splashing and grinding debris from spreading, improve the processing environment, reduce pollution to the precision parts of the machine tool, reduce noise during high-speed grinding, suppress dust and water mist escape, and ensure operational safety.

[0015] Preferably, a first pulley is rotatably connected to the top of the outer casing, the outer wall of the first pulley being in contact with the outer wall of the wire rope; a second pulley is rotatably connected to the top of the outer casing, the outer wall of the second pulley being in contact with the outer wall of the wire rope; and a third pulley is rotatably connected to the side wall of the outer casing, the outer wall of the third pulley being in contact with the outer wall of the wire rope.

[0016] By adopting the above technical solution and setting the first pulley, the second pulley, and the third pulley, the wire rope can be protected, avoiding significant wear between the wire rope and the outer casing during sliding, thereby preventing any impact on the wire rope's pulling and releasing of the closed door.

[0017] Preferably, the water spray assembly includes a water collection tank, the outer wall of which is fixedly connected to the top of the outer shell, and a spray pipe is fixedly connected to the bottom of the water collection tank.

[0018] By adopting the above technical solution and setting up a water spray component, grinding heat can be quickly removed, avoiding thermal deformation and burning of the workpiece spherical surface, ensuring machining accuracy, and at the same time suppressing dust diffusion, protecting the precision components of the machine tool, and extending the service life of the equipment.

[0019] Preferably, a sealing plate is fixedly connected to the top of the base, the sealing plate has holes, and the outer wall of the sealing plate is fixedly connected to the inner wall of the outer shell.

[0020] By adopting the above technical solution and setting a sealing plate, the splashing of cooling water can be prevented, thus avoiding damage to some components by wastewater. The holes set on the sealing plate can facilitate the movement of the cup-shaped grinding wheel, thereby facilitating the grinding of the ball head.

[0021] In summary, the present invention has at least one of the following beneficial technical effects: 1. By setting up a grinding wheel assembly and a repair assembly, a fourth motor drives a lead screw to move a drive plate and a spring telescopic plate. This allows the fixed plate to insert the spring telescopic plate into the inside of the cup-shaped grinding wheel, and the cup-shaped grinding wheel is moved to the ball head position. Simultaneously, a third motor can directly drive a worm gear to rotate, thereby directly driving two sets of cup-shaped grinding wheels to rotate. This allows one set of cup-shaped grinding wheels to grind the ball head, while the other set idles. At this time, a repair tool can be used to repair the idle cup-shaped grinding wheel, thus achieving the effect of one set grinding and one set repairing, thereby improving the grinding efficiency of the device on the ball head.

[0022] 2. By setting up grinding components, the ball head can be clamped, rotated, and oscillated. Clamping can be adapted to different specifications of rods, avoiding axial movement of the workpiece during processing and ensuring the consistency of batch processing accuracy. Rotation can make all parts of the spherical surface participate in grinding evenly, eliminating local wear unevenness and processing blind spots caused by single-point contact, and improving the roundness and contour consistency of the spherical surface. Oscillation can complete the grinding of the entire spherical surface of the ball head without dead angles, eliminating processing blind spots and improving the roundness and contour accuracy of the spherical surface.

[0023] 3. By setting up a flipping component, the support table can be driven to rotate during reset, thereby allowing the two sets of cup-shaped grinding wheels to switch positions. This makes it easier for workers to repair the cup-shaped grinding wheels that have already been ground on the ball head, thus avoiding affecting the overall efficiency of the device.

[0024] 4. By setting up sealing components, it is possible to prevent cooling water from splashing and grinding debris from spreading, improve the processing environment, reduce contamination of precision parts on the outside of the machine tool, reduce noise during high-speed grinding, suppress dust and water mist escape, and ensure operational safety.

The holes provided on the sealing plate 9 can facilitate the movement of the cup-shaped grinding wheel 407, thereby facilitating the grinding of the ball head.

[0037] The implementation principle of this invention is as follows: When the equipment is working, the operator uses the first pneumatic gripper 303 to clamp the ball-shaped workpiece. After the ball-shaped workpiece is clamped, the linear motor drives the second motor 305 and the positioning plate 306 to move, so that the second motor 305 moves directly below the ball-shaped workpiece. After the ball-shaped workpiece is clamped, the fourth motor 701 drives the lead screw 702 to rotate, which drives the drive plate 703 to move along the lead screw 702. The drive plate 703 drives the push ring 705 to move through the spring telescopic plate 704, so that the repair tool 707 is inserted into the cup-shaped grinding wheel 407 to repair the cup-shaped grinding wheel 407. When the push ring 705 moves, it also drives the support table 401 and the support plate 402 to move, so that the cup-shaped grinding wheel 407 is located within the range of the ball. Subsequently, the third motor 403 drives the second pneumatic gripper 406 to rotate the cup-shaped grinding wheel 407 at high speed through the worm gear 404 and the worm wheel 405, providing cutting power for grinding. During the grinding process, the fourth motor 701 drives the lead screw 702 to rotate, which drives the second pneumatic gripper 406 to rotate the cup-shaped grinding wheel 407 at high speed. A motor 302 drives a first pneumatic gripper 303 to rotate the ball-shaped workpiece, achieving uniform grinding of all parts of the spherical surface. Simultaneously, a second motor 305 drives a mounting plate 301 to swing around an axis via an electric telescopic plate 304, forming multi-axis linkage with the workpiece rotation to eliminate blind spots in the machining process. When a set of cup-shaped grinding wheels 407 is grinding the ball, a set of cup-shaped grinding wheels 407 will idle. The idle cup-shaped grinding wheels 407 will be repaired by the repair tool 707. After the ball is ground, the gear 502 at the bottom of the support table 401 meshes with the rack 501 at the bottom of the base 1. When the support table 401 moves, the gear 502 rolls along the rack 501, realizing the flipping and positioning of the support table 401. The first spring telescopic rod 504 drives the locking block 505 to lock and release the gear 502, and together with the blocking bar 507 to limit the fixing bar 506, the grinding wheel assembly 4 is stably fixed, preventing the support table 401 from shaking during the grinding process. The fourth motor 701 drives the mounting wheel 601 to rotate, winding or releasing the wire rope 602. The wire rope 602 is guided by the first pulley 605, the second pulley 606 and the third pulley 607, which drives the sealing door 603 to move up and down along the second spring telescopic rod 604 to seal the grinding area, prevent coolant from splashing and grinding debris from spreading, and protect the precision parts of the machine tool. At the same time, the water spray assembly 8 starts to work: the water tank 801 sprays cooling water through the universal bamboo joint cooling pipe 802 to the grinding contact area between the cup-shaped grinding wheel 407 and the workpiece, quickly removing the grinding heat, preventing the workpiece spherical surface from thermal deformation and burning, and at the same time flushing away the grinding debris, avoiding the grinding wheel pores from becoming clogged and dull, and stabilizing the surface roughness of the workpiece. The sealing plate 9 blocks and guides the cooling wastewater to prevent it from corroding the equipment components and ensures the long-term stable operation of the equipment. After grinding is completed, all components are reset: the cup-shaped grinding wheel 407 stops rotating, the first pneumatic gripper 303 releases the workpiece, the sealing door 603 opens, and the equipment completes a single processing cycle and can proceed to the next batch of workpieces.
