Description

Technical Field

[0001] This invention relates to the field of machining technology, specifically to a precision grinding device for the end face of an external cylindrical grinding machine. Background Technology

[0002] Cylindrical grinding machines are used to process the outer surfaces of workpieces that are cylindrical, conical, or other shaped generatrices, as well as the end faces of shaft shoulders. They are the most widely used type of grinding machine, capable of processing various cylindrical and conical outer surfaces and end faces of shaft shoulders. Among all grinding machines, cylindrical grinding machines are the most widely used type of machine tool. Cylindrical grinding machines can generally be classified into ordinary cylindrical grinding machines, universal cylindrical grinding machines, wide-wheel cylindrical grinding machines, end-face cylindrical grinding machines, multi-wheel head cylindrical grinding machines, multi-blade cylindrical grinding machines, plunge cylindrical grinding machines, and special-purpose cylindrical grinding machines, etc.

[0003] In existing equipment, when grinding the end face of shaft parts, grinding marks will appear on the surface of the grinding block when the end face of the grinding block is continuously ground with the end face of the pipe for a long time. It is necessary to grind and repair the end face of the grinding block in time to avoid the grinding marks being too deep and interfering with the normal pipe grinding work. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this invention is as follows: An external cylindrical grinding machine end face precision grinding device, comprising a main body shell, a clamping component fixedly connected to the top of the outer surface of the main body shell, a fixed seat slidably connected to the end of the top of the main body shell away from the clamping component, a grinding component slidably connected to the middle of the top of the main body shell, an operation panel fixedly connected to the end of the top of the main body shell near the clamping component, a knob threadedly connected to the end of the outer surface of the main body shell near the fixed seat, and a center pin fixedly connected to the middle of the outer surface of the fixed seat.

[0005] The clamping component includes a clamping base, and a chuck is fixedly connected to the middle of the outer surface of the clamping base, and a fixing mechanism is evenly arranged on the outer surface of the chuck.

[0006] The polishing component includes a polishing housing, a motor is fixedly connected to the middle of the outer surface of the polishing housing, and a polishing block is fixedly connected to the output end of the motor. A collecting mechanism is rotatably connected to the bottom of the inner cavity of the polishing housing, a cleaning mechanism is fixedly connected to the middle of the inner cavity of the polishing housing, and a trimming mechanism is fixedly connected to the top of the outer surface of the polishing housing.

[0007] The fixing mechanism includes a fixing block, the outer surface of which is slidably connected to both sides of the chuck cavity. The inner wall of the fixing block has symmetrically formed sliding grooves. A guide rod is fixedly connected to the inner cavity of each sliding groove. A fixing spring is sleeved on the outer surface of the guide rod. The end of the fixing spring near the slide plate is fixedly connected to the end of the slide plate's outer surface near the fixing spring. The end of the fixing spring away from the slide plate is fixedly connected to the end of the inner wall of the sliding groove near the guide rod. A slide plate is slidably connected to the outer surface of the guide rod. A scraper is fixedly connected to the middle of the outer surface of the slide plate. During operation, the pipe to be processed is clamped... In the middle of the clamping seat, the fixed block slides within the chuck cavity by rotating the chuck, thereby clamping and fixing the pipe to be processed. When the pipe is clamped and fixed, as the pipe passes through the middle of the clamping seat, it abuts against the sliding plate, squeezing the sliding plate. As the pipe moves through the middle of the clamping seat, the scraper can clean the surface of the pipe to be processed. As the pipe continues to move in the middle of the clamping seat, the sliding plate drives the sliding plate to slide on the outer surface of the guide rod, thereby causing the sliding plate to retract at one end of the sliding groove, thus avoiding interference with the clamping of the pipe.

[0008] The trimming mechanism includes a trimming housing. A diamond pen is slidably connected to one end of the outer surface of the trimming housing. The end of the diamond pen's outer surface near the trimming housing is slidably connected to both sides of the inner cavity of the trimming housing. A fixing pin is slidably connected to the middle of the diamond pen's outer surface. The outer surface of the fixing pin is slidably connected to both sides of the inner cavity of the fixing hole. A brush is fixedly connected to the end of the diamond pen's outer surface away from the trimming housing. Fixing holes are evenly distributed on the end of the trimming housing's outer surface near the diamond pen. A trimming spring is fixedly connected to the bottom of the diamond pen's outer surface. The end of the trimming spring's outer surface near the trimming housing is fixedly connected to the bottom of the inner cavity of the trimming housing. The end of the trimming spring's outer surface away from the trimming housing is fixedly connected to the bottom of the inner cavity of the trimming housing. One end of the shell is fixedly connected to the end of the diamond pen's outer surface near the trimming spring. After the end face of the tube is finished, when the outer surface of the tube needs to be polished, the position of the grinding shell is adjusted through the control panel, so that the grinding block polishes the outer surface of the tube. By adjusting the rotary knob, the screw fixing seat is rotated, so that the fixing seat moves on the top of the main shell, so that the pin is fixed in the middle of the tube. When the outer surface of the grinding block needs to be trimmed, the fixing pin is rotated to disengage from the fixing hole, so that the height of the diamond pen is adjusted. At the same time, the brush is set to sweep away the waste generated during trimming.

[0009] The collection mechanism includes a collection housing. Collection plates are evenly distributed on the outer surface of the collection housing. The center of the outer surface of each collection plate is rotatably connected to the center of the inner cavity of the collection housing via a connector. A striking block is evenly distributed on the center of the outer surface of the collection housing. The outer surface of the striking block is slidably connected to both sides of the inner cavity of the collection plate. A collection spring is fixedly connected to one end of the outer surface of the striking block near the collection housing, and the end of the outer surface of the collection spring away from the striking block is fixedly connected to the center of the outer surface of the collection housing. When the grinding block rotates within the inner cavity of the grinding housing, the generated waste chips and residues are discharged through… After being cleaned by the cleaning mechanism, the waste falls into the inner cavity of the collection shell. As the grinding block rotates, it comes into contact with the surface of the striking block. This rotation of the grinding block causes the collection shell to rotate, thus collecting the waste debris that has fallen and accumulated at the bottom of the inner cavity of the grinding shell through the collection plate. As the collection shell rotates, the centrifugal force stretches the collection spring, causing the striking block to strike the inner wall of the grinding shell, thereby knocking off the waste material attached to the grinding shell.

[0010] The cleaning mechanism includes a cleaning frame, a cleaning block fixedly connected to the middle of the outer surface of the cleaning frame, a rotating frame rotatably connected to the top of the outer surface of the cleaning frame, connecting rods evenly arranged at the end of the outer surface of the cleaning frame away from the rotating frame, a small spring fixedly connected to the bottom of the inner cavity of the connecting rod, the end of the outer surface of the small spring away from the bottom of the inner cavity of the connecting rod being fixedly connected to the end of the outer surface of the connecting block away from the cleaning frame, a connecting block slidably connected to the middle of the inner cavity of the connecting rod via a socket, the outer surface of the connecting block being slidably connected to both sides of the inner cavity of the connecting rod, an iron plate evenly arranged at the end of the outer surface of the connecting block near the cleaning block, a cleaning spring fixedly connected to the end of the outer surface of the cleaning frame away from the cleaning block, and the end of the outer surface of the cleaning spring away from the cleaning frame being fixedly connected to the middle of the inner wall of the grinding shell. By turning on the motor, the grinding block is rotated in the inner cavity of the grinding shell through the drive of the motor output end, thereby grinding the pipe on the fixed seat. When the end face of the grinding block is... When pipes are continuously polished for extended periods, polishing marks will appear on the surface of the polishing block. Timely polishing and finishing of the end faces of the polishing block are necessary to prevent excessively deep marks from interfering with normal pipe polishing. The polishing block rotates within the inner cavity of the polishing housing. As it passes through the cleaning frame, the rotating frame cleans the outer surface of the polishing block, removing any residual iron filings generated during pipe polishing. This prevents iron filings from adhering to the surface of the cleaning block during cleaning, which would otherwise become stuck between the polishing and cleaning blocks, causing unevenness on the surface of the polishing block and interfering with the polishing of the pipe end faces. After the cleaning block finishes cleaning the polishing block, the polishing block continues to rotate, causing the iron plate to slide through the connecting block within the inner cavity of the connecting rod. This scrapes off the waste material generated during the polishing block cleaning process, placing it inside the inner cavity of the polishing housing.

[0011] The beneficial effects of this invention are as follows:

[0012] 1. This invention uses a fixing mechanism to clamp and fix the pipe to be processed. When the pipe passes through the middle of the clamping seat, it squeezes the sliding plate, allowing the pipe to be cleaned by the scraper. As the pipe moves continuously in the middle of the clamping seat, the sliding plate drives the sliding plate to slide on the outer surface of the guide rod, causing the sliding plate to retract at one end of the sliding groove, thus avoiding interference with the clamping of the pipe. When the pipe is clamped and fixed, iron filings adhere to the surface of the pipe, creating a clamping height difference, which causes deviation when grinding the end face of the pipe.

[0013] 2. This invention, through the inclusion of a cleaning mechanism, addresses the issue that when the end face of the grinding block is continuously ground against the pipe for an extended period, grinding marks will accumulate on the surface of the grinding block. Timely grinding and trimming of the end face of the grinding block is necessary to prevent excessively deep grinding marks from interfering with normal pipe grinding operations. The grinding block rotates within the inner cavity of the grinding housing. As it passes through the cleaning frame, the rotating frame cleans the outer surface of the grinding block, removing any residual iron filings adhering to the grinding block and generated during pipe grinding. This prevents the cleaning block from further damaging the grinding surface. When the surface of the block is cleaned and polished, iron filings adhere to the surface of the cleaning block. This causes the iron filings to get stuck between the polishing block and the cleaning block during the cleaning process, resulting in unevenness on the surface of the polishing block and interfering with the polishing work on the end face of the pipe. After the cleaning block finishes cleaning and polishing the polishing block, the polishing block continues to rotate, causing the iron plate to slide in the inner cavity of the connecting rod through the connecting block. This scrapes off the waste generated after the polishing work and places it in the inner cavity of the polishing shell.

[0014] 3. This invention, by setting up a dressing mechanism, fixes the top pin to the middle of the pipe by adjusting the rotating knob, preventing vibration during the grinding of the pipe surface. When the outer surface of the grinding block is uneven and needs to be dressed, the fixing pin is rotated to disengage from the fixing hole, thereby adjusting the height of the diamond pen according to the different thicknesses of the grinding wheel dressing. At the same time, a brush is set up to sweep away the waste generated during dressing.

[0015] 4. This invention, by setting up a collection mechanism, allows the waste chips and residues generated when the grinding block rotates within the inner cavity of the grinding shell to be cleaned by a cleaning mechanism. The waste then falls into the inner cavity of the collection shell. The rotation of the grinding block simultaneously drives the collection shell to rotate, thus collecting the waste chips that have fallen and accumulated at the bottom of the inner cavity of the grinding shell into the inner cavity of the collection shell via a rotating collection plate. As the collection shell rotates, centrifugal force stretches the collection spring, causing the striking block to strike the inner wall of the grinding shell, thereby shaking off the waste materials attached to the grinding shell, thus facilitating the collection process.

The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0026] Example, using Figures 1-8 The following describes a precision grinding apparatus for the end face of an external cylindrical grinding machine according to an embodiment of the present invention.

[0027] like Figures 1-8As shown, a precision grinding device for the end face of an external cylindrical grinding machine according to the present invention includes a main body shell 1, a clamping component 2 fixedly connected to the top of the outer surface of the main body shell 1, a fixed seat 4 slidably connected to the end of the top of the main body shell 1 away from the clamping component 2, a grinding component 3 slidably connected to the middle of the top of the main body shell 1, an operation panel 5 fixedly connected to the end of the top of the main body shell 1 near the clamping component 2, a knob 6 threadedly connected to the end of the outer surface of the main body shell 1 near the fixed seat 4, and a pin 7 fixedly connected to the middle of the outer surface of the fixed seat 4.

[0028] The clamping component 2 includes a clamping seat 21, a chuck 22 is fixedly connected to the middle of the outer surface of the clamping seat 21, and a fixing mechanism 23 is evenly arranged on the outer surface of the chuck 22.

[0029] The polishing component 3 includes a polishing housing 31, a motor 32 fixedly connected to the middle of the outer surface of the polishing housing 31, and a polishing block 33 fixedly connected to the output end of the motor 32. A collecting mechanism 34 is rotatably connected to the bottom of the inner cavity of the polishing housing 31. A cleaning mechanism 35 is fixedly connected to the middle of the inner cavity of the polishing housing 31. A trimming mechanism 36 is fixedly connected to the top of the outer surface of the polishing housing 31.

[0030] The fixing mechanism 23 includes a fixing block 231. The outer surface of the fixing block 231 is slidably connected to both sides of the inner cavity of the chuck 22. The inner wall of the fixing block 231 is symmetrically provided with sliding grooves 232. A guide rod 233 is fixedly connected to the inner cavity of the sliding groove 232. A fixing spring 235 is sleeved on the outer surface of the guide rod 233. One end of the fixing spring 235 near the slide plate 234 is fixedly connected to the other end of the outer surface of the slide plate 234 near the fixing spring 235. The other end of the fixing spring 235 away from the slide plate 234 is fixedly connected to the inner wall of the sliding groove 232 near the guide rod 233. The slide plate 234 is slidably connected to the outer surface of the guide rod 233. A scraper 236 is fixedly connected to the middle of the outer surface of the slide plate 234. During operation, the tube to be processed is... The material passes through the middle of the clamping seat 21. By rotating the chuck 22, the fixing block 231 slides in the inner cavity of the chuck 22, thereby clamping and fixing the pipe to be processed. When the pipe is clamped and fixed, as the pipe passes through the middle of the clamping seat 21, the pipe abuts against the sliding plate 234, squeezing the sliding plate 234. As the pipe moves through the middle of the clamping seat 21, the scraper 236 can clean the surface of the pipe to be processed. When the pipe continues to move in the middle of the clamping seat 21, the sliding plate 234 drives the sliding plate 234 to slide on the outer surface of the guide rod 233. As a result, the sliding plate retracts at one end of the sliding groove 232, thereby avoiding interference with the clamping of the pipe.

[0031] The trimming mechanism 36 includes a trimming housing 361. A diamond pen 362 is slidably connected to one end of the outer surface of the trimming housing 361. The end of the outer surface of the diamond pen 362 near the trimming housing 361 is slidably connected to both sides of the inner cavity of the trimming housing 361. A fixing pin 364 is slidably connected to the middle of the outer surface of the diamond pen 362. The outer surface of the fixing pin 364 is slidably connected to both sides of the inner cavity of the fixing hole 366. A brush 363 is fixedly connected to the end of the outer surface of the diamond pen 362 away from the trimming housing 361. Fixing holes 366 are evenly distributed on the outer surface of the trimming housing 361 near the diamond pen 362. A trimming spring 365 is fixedly connected to the bottom of the outer surface of the diamond pen 362. The end of the outer surface of the trimming spring 365 near the trimming housing 361 is fixedly connected to the bottom of the inner cavity of the trimming housing 361. The end of the surface away from the trimming housing 361 is fixedly connected to the end of the diamond pen 362 near the trimming spring 365. When the end face of the tube is finished and the outer surface of the tube needs to be trimmed, the position of the trimming housing 31 is adjusted by the operation panel 5, so that the trimming block 33 can trim the outer surface of the tube. By adjusting the rotary knob 6, the screw fixing seat is rotated, so that the fixing seat 4 moves on the top of the main housing 1, so that the ejector pin 7 is fixed to the middle of the tube. When the outer surface of the trimming block 33 needs to be trimmed, the fixing pin 364 is rotated to disengage from the fixing hole 366, so that the height of the diamond pen 362 is adjusted. At the same time, the brush 363 is set to sweep away the waste generated during trimming.

[0032] The collection mechanism 34 includes a collection housing 341. Collection plates 342 are evenly distributed on the outer surface of the collection housing 341. The center of the outer surface of the collection plates 342 is rotatably connected to the center of the inner cavity of the collection housing 341 via a slot. A striking block 343 is evenly distributed on the center of the outer surface of the collection housing 341. The outer surface of the striking block 343 is slidably connected to both sides of the inner cavity of the collection plates 342. A collection spring 344 is fixedly connected to one end of the outer surface of the striking block 343 near the collection housing 341. The end of the outer surface of the collection spring 344 away from the striking block 343 is fixedly connected to the center of the outer surface of the collection housing 341. When the grinding block 33 rotates within the inner cavity of the grinding housing 31, the generated waste chips and residues are collected by a cleaning machine. After cleaning by the structure 35, the waste falls into the inner cavity of the collection shell 341. The grinding block 33 rotates, causing it to contact the surface of the striking block 343. As the grinding block 33 rotates, it drives the collection shell 341 to rotate, thus collecting the waste debris that has fallen and accumulated at the bottom of the inner cavity of the grinding shell 31 through the collection plate 342. The collection plate 342 collects the waste debris into the inner cavity of the collection shell 341. When the collection shell 341 rotates, the centrifugal force stretches the collection spring 344, causing the striking block 343 to strike the inner wall of the grinding shell 31, thereby knocking off the waste material attached to the grinding shell 31.

[0033] The cleaning mechanism 35 includes a cleaning frame 351. A cleaning block 352 is fixedly connected to the middle of the outer surface of the cleaning frame 351. A rotating frame 353 is rotatably connected to the top of the outer surface of the cleaning frame 351. Connecting rods 355 are evenly arranged at the end of the outer surface of the cleaning frame 351 away from the rotating frame 353. A small spring 357 is fixedly connected to the bottom of the inner cavity of the connecting rod 355. The end of the outer surface of the small spring 357 away from the bottom of the inner cavity of the connecting rod 355 is fixedly connected to the end of the outer surface of the connecting block 356 away from the cleaning frame 351. The connecting block 356 is slidably connected to the middle of the inner cavity of the connecting rod 355 through a socket. The outer surface of the connecting block 356 is slidably connected to both sides of the inner cavity of the connecting rod 355. Iron plates 358 are evenly distributed on the outer surface of the connecting block 356 near the cleaning block 352. A cleaning spring 354 is fixedly connected to the outer surface of the cleaning frame 351 away from the cleaning block 352. The outer surface of the cleaning spring 354 away from the cleaning frame 351 is fixedly connected to the middle of the inner wall of the grinding housing 31. By turning on the motor 32, the output of the motor 32 drives the grinding block 33 to rotate within the inner cavity of the grinding housing 31, thereby grinding the pipe on the fixed seat 4. When the end face of the grinding block 33 is continuously ground against the pipe for an extended period, grinding marks will appear on the surface of the grinding block 33. Timely grinding and trimming of the end face of the grinding block 33 is necessary to prevent excessively deep grinding marks from interfering with normal pipe grinding. The grinding block 33 rotates within the inner cavity of the grinding housing 31. As it passes through the cleaning frame 351, the rotating frame 353 cleans the outer surface of the grinding block 33, removing any residual iron filings generated during the grinding of the pipe. This prevents iron filings from being released when the cleaning block 352 cleans the surface of the grinding block 33. The metal filings adhere to the surface of the cleaning block 352, causing the grinding block 33 to become stuck between the grinding block 33 and the cleaning block 352 during cleaning. This causes unevenness on the surface of the grinding block 33, interfering with the grinding work of the grinding block 33 on the end face of the pipe. After the cleaning block 352 finishes cleaning and grinding the grinding block 33, the grinding block 33 continues to rotate, causing the iron plate 358 to slide in the inner cavity of the connecting rod 355 through the connecting block 356. This scrapes off the waste generated after cleaning the grinding block 33 and places it in the inner cavity of the grinding housing 31.

[0034] The specific workflow is as follows:

[0035] During operation, the pipe to be processed is passed through the middle of the clamping seat 21. The chuck 22 is rotated, causing the fixing block 231 to slide within the chuck 22's inner cavity, thus clamping and fixing the pipe. When the pipe passes through the middle of the clamping seat 21, it abuts against the sliding plate 234. The scraper 236 cleans the surface of the pipe. As the pipe moves continuously through the middle of the clamping seat 21, the sliding plate 234 slides on the outer surface of the guide rod 233, causing it to retract at one end of the sliding groove 232, thus avoiding interference with the clamping operation. By turning on the motor 32... Driven by the output of motor 32, the grinding block 33 rotates within the inner cavity of the grinding housing 31, thereby grinding the pipe on the fixed base 4. When passing through the cleaning frame 351, the rotating frame 353 cleans the outer surface of the grinding block 33, removing any residual iron filings generated during grinding. After the cleaning block 352 finishes cleaning the grinding block 33, the grinding block 33 continues to rotate, causing the iron plate 358 to slide within the inner cavity of the connecting rod 355 via the connecting block 356. This scrapes off the waste material generated after cleaning the grinding block 33, placing it within the inner cavity of the grinding housing 31. The outer surface of the pipe needs to be... During grinding, the position of the grinding housing 31 is adjusted via the control panel 5, allowing the grinding block 33 to grind the outer surface of the pipe. Adjusting the rotary knob 6 rotates the threaded fixing seat 4, moving it on top of the main housing 1. This allows the ejector pin 7 to fix the middle of the pipe, preventing vibration during grinding. When the outer surface of the grinding block 33 is uneven and needs adjustment, the fixing pin 364 is rotated to disengage from the fixing hole 366, adjusting the height of the diamond pen 362 to suit different grinding wheel thicknesses. Simultaneously, the brush 36... 3. The waste generated during the finishing process is swept off. The grinding block 33 rotates, causing it to contact the surface of the striking block 343. As the grinding block 33 rotates, it drives the collection shell 341 to rotate as well. The waste that has fallen and accumulated at the bottom of the inner cavity of the grinding shell 31 is collected by the collection plate 342 within the inner cavity of the collection shell 341. When the collection shell 341 rotates, the centrifugal force stretches the collection spring 344, causing the striking block 343 to strike the inner wall of the grinding shell 31, thereby knocking off the waste attached to the grinding shell 31 and facilitating the collection process.
