Description

Technical Field

[0001] This invention belongs to the technical field of grinding machine parts and equipment, and particularly relates to a grinding head holder for a grinding machine. Background Technology

[0002] A grinding machine is a machine tool used for grinding workpieces. It is widely used in machining and manufacturing industries. It consists of many parts, each with its specific function and role, including spindle, die, feed mechanism, worktable, cutting fluid supply system, etc. The grinding head is the cutting tool used by the grinding machine to cut away the surface of the workpiece to achieve the required precision and surface quality. Common grinding heads include grinding wheels, abrasive belts, and abrasive cloths. The grinding head material, shape, adhesive, and combination method all affect the grinding effect.

[0003] When the grinding head is installed, it is first installed in the grinding head holder, and then the grinding head is connected to the grinding machine by using the connection between the grinding head holder and the grinding machine. When the grinding head is connected to the grinding machine, there are the following problems: (1) When the grinding head is rotating and in contact with the workpiece to be ground, it will generate thrust in different directions on the grinding head. Although the grinding head and the grinding head holder are in a stable state at the beginning of installation, as time goes by and the grinding head is subjected to the pressure of the workpiece grinding for a long time, it will have a certain vibration effect on the connection stability between the grinding rod and the grinding head holder, causing the grinding head to shift. For this kind of vibration shift, when the distance is large, it can be directly observed by man. However, when the distance is small in the initial stage of the shift, it cannot be detected by man, thus affecting the continued expansion of the subsequent shift, which may harm the subsequent operation of the grinding head.

[0004] (2) Due to the variety of types of workpieces to be ground, when using a grinding machine to grind them, the appropriate grinding head time is often selected according to the shape, size and type of the workpiece. However, the existing grinding head holder is fixed and integrated with the grinding machine, so the types of grinding heads that the grinding head holder can be adapted to are limited. It is not possible to change different grinding heads according to the type of workpiece. Moreover, the grinding rods that need to be ground are of different thicknesses (i.e., there are conical, cylindrical, rectangular, etc.) and have different shapes. When they are installed and connected to the grinding head holder, a specific positioning structure is often required. This leads to higher installation requirements for the grinding head holder and reduces the applicability of the grinding head holder.

[0005] Therefore, in view of the above-mentioned problems, this technical solution proposes a grinding head holder for grinding machines. Summary of the Invention

[0006] The purpose of this invention is to provide a grinding head holder for a grinding machine, which aims to solve the following problems.

[0007] This invention is implemented as follows: A structural diagram of a grinding head holder for a grinding machine includes: a grinding head holder base; a slot is formed on one side of the grinding head holder base; a swing body is detachably installed in the slot; a through grinding head mounting hole is formed inside the swing body for mounting the grinding head; fixing pins are symmetrically arranged on both sides of the slot perpendicular to the axis of the grinding head mounting hole; the ends of the fixing pins extend through the wall of the grinding head mounting hole into the interior of the grinding head mounting hole; the fixing pins are used to fix the swing body in the slot and extend into the interior of the grinding head mounting hole to hold and position the grinding head component inside the grinding head mounting hole; a vibration detection mechanism is provided inside the grinding head holder base corresponding to one side of the swing body; the vibration detection mechanism is used to automatically detect whether the swing body deviates during the operation of the grinding head and to automatically reset and adjust the amount of deviation; the vibration detection mechanism includes a rectangular swing groove formed in one side wall of the swing body; a swing plate is embedded in the swing groove by fastening bolts distributed parallel to the axis of the grinding head mounting hole; the end of the swing plate away from the swing groove extends into the swing plate formed inside the grinding head holder base. In the detection groove, when the swing plate is in its initial position, it is placed in the middle of the swing detection groove in the transverse direction. Two sets of proximity sensors are symmetrically arranged on both sides of the same end of the swing plate inside the swing detection groove. The proximity sensors are used to detect the position of their ends relative to the swing plate in real time. Pneumatic pistons are set inside the grinding head base corresponding to the transverse sides of the swing plate. The pneumatic pistons move relative to the swing plate to reset and adjust the swing plate after it has shifted. Since the swing body is fixed by two sets of fixing pins that are perpendicular to the axial direction of the grinding head mounting hole, the grinding head running inside the grinding head mounting hole will generate a vibration effect on the swing body that moves along the axial direction of the grinding head mounting hole. As the vibration frequency and amplitude continue, it will gradually cause a certain distance displacement of the swing plate embedded in the swing groove. Once the swing plate shifts laterally, the proximity sensors on both sides will monitor it in real time. Once displacement occurs, the pneumatic pistons on both sides of the swing plate will be activated to reset the swing plate from a relative angle. Then, the swing body will be reset synchronously by using the embedded connection between the swing plate and the swing groove.

[0008] The grinding head rod mounting and positioning cylinder is detachably installed inside the grinding head mounting hole. Both ends of the grinding head rod mounting and positioning cylinder are open, one end is used for the entry and exit of the grinding head rod, and the other end is detachably equipped with a power shaft. The power shaft is used to connect with the grinding head rod installed inside the grinding head rod mounting and positioning cylinder, that is, to drive the grinding head rod to drive the grinding head to rotate. The grinding head rod mounting and positioning cylinder located at the inner end of the fixing pin has a pressing and positioning surface on its circumferential side wall. The pressing and positioning surface contacts the end of the fixing pin, thereby realizing the pressing and positioning of the grinding head rod mounting and positioning cylinder by the fixing pin.

[0009] The adaptive positioning mechanism is provided with multiple sets of rotating and uniformly distributed rings on the inner wall of the grinding head rod mounting and positioning cylinder. The adaptive positioning mechanism is used to adaptively clamp and position the grinding head rod inserted into the grinding head rod mounting and positioning cylinder. That is, according to the different shapes of the grinding head rod, the adaptive positioning mechanism automatically adjusts the clamping force and applies a balanced and sufficient clamping force from the circumferential side wall of the grinding head rod, thereby realizing the function of the grinding head rod mounting and positioning cylinder to install and fix different types of grinding head rods.

[0010] The present invention provides a grinding head holder for a grinding machine, which can automatically and quickly detect and reset the offset of the swing body and grinding head by utilizing the cooperation of a swing plate, a swing groove, a proximity sensor and a pneumatic piston, so as to ensure the long-term normal operation of the grinding head and realize the automatic detection and reset function of the grinding head holder.

[0011] By utilizing the detachable installation of the grinding head rod mounting positioning cylinder and the grinding head mounting hole, and the self-adaptive positioning mechanism set inside the grinding head rod mounting positioning cylinder, this grinding head holder achieves the function of easy adjustment and installation / removal. At the same time, the self-adaptive positioning mechanism is used to clamp and position grinding head rods of different shapes in a balanced and stable manner, realizing the applicability of this grinding head holder to various types of grinding heads and expanding the application range of this grinding head holder.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0029] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0030] like Figure 1-8The diagram shown is a structural diagram of a grinding head holder provided in an embodiment of the present invention. It includes: a grinding head holder base 10; a slot is formed on one side of the grinding head holder base 10; a swing body 13 is detachably installed in the slot; a through grinding head mounting hole 11 is formed inside the swing body 13; the grinding head mounting hole 11 is used for mounting the grinding head; fixing pins 17 are symmetrically arranged on both sides of the slot perpendicular to the axis of the grinding head mounting hole 11; the ends of the fixing pins 17 extend through the wall of the grinding head mounting hole 11 into the grinding head mounting hole 11; the fixing pins 17 are used to fix the swing body 13 in the slot while also extending into the grinding head mounting hole 11 to mount the grinding head. The grinding head assembly inside the mounting hole 11 is held and positioned. A vibration detection mechanism is provided inside the grinding head base 10 on one side of the swing body 13. The vibration detection mechanism is used to automatically detect whether the swing body 13 is offset during the operation of the grinding head and to automatically reset and adjust the offset. The vibration detection mechanism includes a rectangular swing groove 16 opened in one side wall of the swing body 13. A swing plate 15 is embedded in the swing groove 16 by fastening bolts distributed parallel to the axis of the grinding head mounting hole 11. The end of the swing plate 15 away from the swing groove 16 extends to the swing detection mechanism opened inside the grinding head base 10. In the slot 18, when the oscillating plate 15 is in its initial position, it is placed in the transverse inner center of the oscillation detection slot 18. Two sets of proximity sensors 19 are symmetrically arranged on both sides of the same end of the oscillating plate 15 inside the oscillation detection slot 18. The proximity sensors 19 are used to detect the position of their ends relative to the oscillating plate 15 in real time. Pneumatic pistons 14 are installed inside the grinding head base 10 corresponding to the transverse sides of the oscillating plate 15. The pneumatic pistons 14 move relative to the oscillating plate 15 to reset and adjust the oscillating plate 15 after it has shifted. The oscillating body 13 is fixed by two sets of fixing pins 17 distributed axially perpendicular to the grinding head mounting holes 11. The grinding head running inside the grinding head mounting hole 11 will generate a vibration effect on the swing body 13 along the axial movement of the grinding head mounting hole 11. As the vibration frequency and amplitude continue, it will gradually cause a certain distance displacement of the swing plate 15 embedded in the swing groove 16. Once the swing plate 15 is laterally displaced, the proximity sensors 19 placed on both sides will monitor it in real time. Once displacement occurs, the pneumatic pistons 14 on both sides of the swing plate 15 will be activated to reset the swing plate 15 from a relative angle. Then, by using the embedded connection between the swing plate 15 and the swing groove 16, the swing body 13 will be reset simultaneously.

[0031] The grinding head rod mounting and positioning cylinder 20 is detachably installed inside the grinding head mounting hole 11. Both ends of the grinding head rod mounting and positioning cylinder 20 are open. One end is used for the entry and exit of the grinding head rod, and the other end is detachably equipped with a power shaft 21. The power shaft 21 is used to connect with the grinding head rod installed inside the grinding head rod mounting and positioning cylinder 20, that is, to drive the grinding head rod to drive the grinding head to rotate. The grinding head rod mounting and positioning cylinder 20 located at the inner end of the fixing pin 17 has a pressing and positioning surface 26 on its circumferential side wall. The pressing and positioning surface 26 contacts the end of the fixing pin 17, thereby realizing the pressing and positioning of the grinding head rod mounting and positioning cylinder 20 by the fixing pin 17.

[0032] The adaptive positioning mechanism is provided with multiple sets of rotating and uniformly distributed rings on the inner wall of the grinding head rod mounting and positioning cylinder 20. The adaptive positioning mechanism is used to adaptively clamp and position the grinding head rod inserted into the grinding head rod mounting and positioning cylinder 20. That is, according to the different shapes of the grinding head rod, the adaptive positioning mechanism automatically adjusts the clamping force and applies a balanced and sufficient clamping force from the circumferential side wall of the grinding head rod, thereby realizing the function of the grinding head rod mounting and positioning cylinder 20 to install and fix different types of grinding head rods.

[0033] Before use, the grinding head rod mounting and positioning cylinder 20 is inserted into the grinding head mounting hole 11 and then held and positioned by the fixing pin 17. The cylinder 20 itself is also used to stably fix the grinding head rod mounting and positioning cylinder 20 within the grinding head mounting hole 11. Simultaneously, one end of the grinding head rod mounting and positioning cylinder 20 is connected to the power shaft 21. Then, the grinding head to be used inserts its rod section (grinding head rod) into the grinding head rod mounting and positioning cylinder 20. The inner end of the grinding head rod is connected to the power shaft 21, and the outer side of the middle of the grinding head rod is adaptively positioned by multiple sets of adaptive positioning mechanisms. Driven by the power shaft 21, the grinding head rod and the grinding head placed outside the grinding head mounting hole 11 rotate synchronously to grind the workpiece. During the grinding process, due to the various action and reaction forces applied in contact with the workpiece, the grinding head rod undergoes axial displacement. This causes the swing body 13 to shift synchronously, gradually adjusting the position of the grinding head rod. The swing plate 15 inside the swing groove 16 causes a certain distance displacement. Once the swing plate 15 shifts laterally, the proximity sensors 19 on both sides will monitor it in real time. Once displacement occurs, the pneumatic pistons 14 on both sides of the swing plate 15 will be activated to reset the swing plate 15 from a relative angle. Then, by using the embedded connection between the swing plate 15 and the swing groove 16, the swing body 13 will be reset simultaneously. That is, by using the cooperation of the swing plate 15, the swing groove 16, the proximity sensor 19, and the pneumatic piston 14, the automatic and rapid detection and reset of the swing body 13 and the grinding head when they shift can be realized, ensuring the long-term normal operation of the grinding head. Then, by using the detachable installation of the grinding head rod mounting positioning cylinder 20 and the grinding head mounting hole 11, as well as the adaptive positioning mechanism set inside the grinding head rod mounting positioning cylinder 20, the installation and removal of this grinding head seat can be made convenient and applicable to different grinding heads, greatly improving the replacement and application range of the grinding head.

[0034] In this embodiment of the invention, although the fixing pin 17 is embedded inside the grinding head mounting hole 11, due to the structural characteristics of the fixing pin 17, it can only ensure the pressing and positioning of components such as the grinding head placed inside the grinding head mounting hole 11. Along the axial direction of the grinding head mounting hole 11, there is a certain gap between the fixing pin 17 and the hole wall of the grinding head mounting hole 11. Therefore, it is impossible to guarantee that the axial displacement of the grinding head mounting hole 11 can be limited by the fixing pin 17. Therefore, it is necessary to use the embedded connection of the swing plate 15 inside the swing groove 16, and then cooperate with the proximity sensor 19 to detect the movement of the swing plate 15, and then cooperate with the pneumatic piston 1... The movement of 4 directly adjusts the swing plate 15 and indirectly resets the swing body 13 and the grinding head and other components inside the grinding head mounting hole 11. At the same time, the pneumatic piston 14 and the proximity sensor 19 are electrically connected to the control module. That is, when the proximity sensor 19 detects that the swing plate 15 has shifted, it transmits the detected information to the control module. The control module analyzes and processes the information and then synchronously controls the pneumatic piston 14 to reset the swing plate 15. The connection structure and operating principle between the pneumatic piston 14, the proximity sensor 19 and the control module are existing technologies and will not be described in detail here.

[0035] It should be noted that although the adaptive positioning mechanism has an internal elastic structure when it clamps the grinding head rod in contact, the elastic structure can be fully compressed under the drive of the corresponding kinetic energy to ensure that the clamped grinding head rod is fixed in a sufficiently stable manner.

[0036] In one example of the present invention, such as Figures 9-11 As shown, the end of the grinding head rod mounting positioning cylinder 20 facing the power shaft 21 is connected to the positioning cylinder connecting ring 23 by a locking pin and a locking groove. The center of the positioning cylinder connecting ring 23 is rotatably connected to the power connecting shaft cylinder 22. The two ends of the power connecting shaft cylinder 22 protrude outward and have hexagonal grooves opened inward at the ends. One end is embeddedly connected to the end of the power shaft 21, and the other end extends into the inside of the grinding head rod mounting positioning cylinder 20 and is embeddedly inserted into the end of the grinding head rod that is inserted into the grinding head rod mounting positioning cylinder 20. Then, under the action of the adaptive positioning mechanism, it remains stable. Then, through the connection of the power shaft 21 and the power connecting shaft cylinder 22, the grinding head rod is synchronously driven to rotate.

[0037] Specifically, a retaining ring 27 is installed on the side of the grinding head rod mounting positioning cylinder 20 away from the power shaft 21. A swing flange 12 is installed on the end of the grinding head mounting hole 11 corresponding to the retaining ring 27. A positioning ring 28 is installed on the side of the retaining ring 27 facing the power shaft 21. A positioning ring groove is opened on the top outer side of the swing flange 12 corresponding to the positioning ring 28. When the grinding head rod mounting positioning cylinder 20 is inserted into the grinding head mounting hole 11, and the retaining ring 27 contacts the swing flange 12, the positioning ring 28 is simultaneously inserted into the positioning ring groove, thereby stably and accurately inserting the grinding head rod mounting positioning cylinder 20 into the grinding head mounting hole 11.

[0038] Specifically, to ensure the stability of the grinding head rod mounting positioning cylinder 20 after it is placed inside the grinding head mounting hole 11, multiple radially distributed positioning screws 24 are connected to the circumferential sidewalls at both ends of the grinding head rod mounting positioning cylinder 20 by annular equally spaced threads. The ends of the positioning screws 24 facing the inside of the grinding head rod mounting positioning cylinder 20 have internal hexagonal screw holes 25, and the other end of the positioning screw 24 is equipped with an arc-shaped positioning post. Positioning screw holes 53 are formed on the inner wall of the grinding head mounting hole 11 corresponding to the arc-shaped positioning post. The grinding head rod mounting positioning cylinder 20 is then... When inserted into the grinding head mounting hole 11, the arc-shaped positioning post is retracted into the inner wall of the grinding head rod mounting positioning cylinder 20 beforehand. Then, when the retaining ring 27 contacts and connects with the swing flange 12, the end of the arc-shaped positioning post moves to the inlet of the corresponding positioning screw hole 53. Then, by using the corresponding hexagonal screw to rotate the internal hexagonal screw hole 25, the positioning screw 24 is rotated. Then, the arc-shaped positioning post is gradually moved toward the inside of the positioning screw hole 53, thereby stably installing the grinding head rod mounting positioning cylinder 20 inside the grinding head mounting hole 11.

[0039] It should be noted that, in order to ensure that the hexagonal screw can be smoothly and conveniently rotated in the internal hexagonal screw hole 25 from outside the grinding head rod mounting positioning cylinder 20, the positioning screws 24 at both ends of the grinding head rod mounting positioning cylinder 20 are distributed close to the openings at both ends of the grinding head rod mounting positioning cylinder 20.

[0040] As a preferred embodiment of the present invention, such as Figure 6 , Figure 7 , Figure 12 , Figure 13 , Figure 14 , Figure 15 The adaptive positioning mechanism has an adaptive positioning mechanism rotation groove 29 on the inner wall of the grinding head rod mounting positioning cylinder 20. The adaptive positioning mechanism rotates and moves along the inside of the adaptive positioning mechanism rotation groove 29. The adaptive positioning mechanism includes a servo motor 32. A positioning slider 51 is mounted on the back of the servo motor 32. A positioning slide rail 52 is provided on the inner ring wall of the adaptive positioning mechanism rotation groove 29 corresponding to the positioning slider 51. The positioning slider 51 rotates in a positioning manner along the inside of the positioning slide rail 52, that is, while keeping the servo motor 32 rotating, the structure of the output end of the servo motor 32 is controlled to be stable.

[0041] The output shaft of the servo motor 32 is connected to a rotating shaft 35. A rotating sleeve 36 is telescopically connected to the end of the rotating shaft 35. A positioning key is installed on the outer circumferential wall of the rotating shaft 35. A positioning slide is formed on the inner wall of the rotating sleeve 36 corresponding to the positioning key. The positioning key and the positioning slide are slidably connected to maintain the axial relative movement between the rotating shaft 35 and the rotating sleeve 36. A moving screw 37 is connected to the end of the rotating sleeve 36 away from the rotating shaft 35. A threaded hole plate 33 is threadedly connected to the outer side of the moving screw 37. A connecting rod is installed at the end of the moving screw 37. A rectangular push plate 34 is provided at the end of the connecting rod. That is, when the servo motor 32 drives the rotating shaft 35 to rotate the rotating sleeve 36, the moving screw 37 moves in the threaded hole plate 34. The threaded section 3 moves laterally, causing the rotating sleeve 36 to move along the rotating shaft 35. Simultaneously, the connecting rod applies a radial thrust to the push plate 34. Two shaft blocks 38 are installed at both ends of the push plate 34 on the side furthest from the connecting rod. One shaft block 38 is connected to a swinging pressure rod 40 and an L-shaped swinging pressure rod 42 via a swinging shaft 39. The other shaft block 38 is connected to a U-shaped swinging pressure rod 41 via a swinging shaft 39. The end of the swinging pressure rod 40 is in contact with one side of the U-shaped swinging pressure rod 41. The ends of the L-shaped swinging pressure rod 42 are oscillatingly connected to adaptive swinging shafts 43 via swinging shafts 39. The ends of the U-shaped swinging pressure rod 41 are also connected to adaptive swinging shafts 43 via swinging shafts 39. The ends of the adaptive swinging shafts 43 are... The device is equipped with swing rollers 44, each with a push block 45 on one side. A telescopic rod 47 is mounted on the side of the push block 45 away from the swing roller 44. The telescopic rods 47 move through an elastic telescopic rod plate 46, and a spring 48 is fitted on the telescopic rods 47 located between the elastic telescopic rod plate 46 and the push block 45. An arc-shaped clamping plate 49 is mounted on the outer end of the telescopic rod 47 away from the push block 45. The arc-shaped clamping plate 49 contacts and clamps the outer wall of the grinding head rod inside the grinding head rod mounting and positioning cylinder 20. When the connecting rod applies a thrust to the push plate 34, the contact thrust of the end of the swing pressure rod 40 on one side of the U-shaped swing pressure rod 41, and the U-shaped swing pressure rod 41, swing pressure rod 40, and L-shaped swing pressure rod 42 through... The swing shaft 39 is oscillatingly connected to the shaft block 38, and the push plate 34 is oscillatingly connected to the L-shaped swing pressure rod 42 and the U-shaped swing pressure rod 41 respectively through the swing shaft 39. This allows the arc-shaped clamping plates 49 at different positions to contact the grinding head rods of different shapes. By utilizing the elastic action of the telescopic rod 47 in the elastic telescopic rod plate 46 in conjunction with the elastic action of the sleeve spring 48, the clamping force of each arc-shaped clamping plate 49 is adaptively adjusted with the grinding head rod to maintain balance. Due to the elastic action of the sleeve spring 48, in order to apply the most stable force to the grinding head rod and prevent the elastic effect of the sleeve spring 48, the moving screw 37 is controlled to maximize the driving force of the connecting rod to apply the pushing force to the push plate 34 during operation, thereby controlling the compression of the sleeve spring 48 to the extreme.

[0042] When clamping the grinding head rod, the adaptive positioning mechanism will rotate synchronously along the rotating groove 29 of the adaptive positioning mechanism. In order to ensure that the push plate 34 and the elastic telescopic rod plate 46 can move smoothly, a base is provided at the bottom of the push plate 34 and the elastic telescopic rod plate 46. One end of the base is fixedly connected to the positioning slider 51. A support slide rod 31 is installed at the bottom of the push plate 34 and the elastic telescopic rod plate 46. A support slide rail 30 is provided on the base corresponding to the bottom end of the support slide rod 31. That is, by moving the support slide rod 31 in the support slide rail 30, stability is provided for the movement of the push plate 34 and the elastic telescopic rod plate 46.

[0043] Specifically, multiple protrusions 50 are evenly installed on the side of the arc-shaped clamping plate 49 that contacts the grinding head rod. The protrusions 50 increase the contact friction between the arc-shaped clamping plate 49 and the grinding head rod, thereby increasing the stability of the multiple arc-shaped clamping plates 49 in contact with and clamping the grinding head rod from the outside.

[0044] The above embodiments of the present invention provide a grinding head holder for a grinding machine. Before use, the grinding head rod mounting positioning cylinder 20 is inserted into the grinding head mounting hole 11, and then positioned by a fixing pin 17. Then, by rotating the internal hexagonal screw hole 25 with a hexagonal screw, the positioning screw 24 is driven to engage its end arc-shaped positioning post with the positioning screw hole 53, thus stably installing the grinding head rod mounting positioning cylinder 20 inside the grinding head mounting hole 11. Finally, the positioning cylinder connecting ring 23 is installed at the end of the grinding head rod mounting positioning cylinder 20. The grinding head rod is inserted into the grinding head rod mounting and positioning cylinder 20. The inner end of the grinding head rod is embedded in the power connection shaft cylinder 22. Then, the servo motor 32 is started to drive the rotation. Under the connection of the moving screw 37, the connecting rod is driven to apply a thrust to the push plate 34. Then, the contact thrust of the end of the swing pressure rod 40 on one side of the U-shaped swing pressure rod 41, and the U-shaped swing pressure rod 41, the swing pressure rod 40, and the L-shaped swing pressure rod 42 are oscillatingly connected to the shaft block 38 through the swing shaft 39. The push plate 34 is respectively connected to the L-shaped... The swing pressure rod 42 and the U-shaped swing pressure rod 41 are swing-connected, so that when the arc-shaped clamping plate 49 at different positions contacts the grinding head rod of different shapes, it controls the arc-shaped clamping plate 49 to apply a balanced and stable clamping force to the grinding head rod, fixing the grinding head rod inside the grinding head rod mounting positioning cylinder 20. Then, driven by the power shaft 21, the grinding head rod and the grinding head placed outside the grinding head mounting hole 11 are driven to rotate synchronously to grind the workpiece. During the grinding process, due to the various action and reaction forces applied by the contact with the workpiece, the grinding head rod will shift axially. At this time, it will drive the swing body 13 to shift synchronously, which will gradually cause the swing plate 15 embedded in the swing groove 16 to shift a certain distance. Once the swing plate 15 shifts laterally, the proximity sensors 19 placed on both sides will monitor it in real time. Once the displacement occurs, the pneumatic pistons 14 on both sides of the swing plate 15 will be activated to reset the swing plate 15 from a relative angle. Then, the swing plate 15 and the swing groove 16 are embedded to reset the swing body 13 synchronously.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
