Description

Technical Field

[0001] This invention relates to the field of camshaft machining technology, and in particular to an intelligent control system and grinding device for camshaft grinding. Background Technology

[0002] The working principle of a camshaft grinding machine is mainly to use a grinding wheel to grind the surface of the camshaft. Most grinding machines include a grinding mechanism and a clamping mechanism. The clamping mechanism holds the camshaft firmly and drives it to rotate, and then the grinding wheel of the grinding mechanism grinds the camshaft.

[0003] In existing technologies, a linear motor is used to drive the grinding mechanism to move, completing the grinding feed and reciprocating following motion. During camshaft grinding, the linear motor drives the grinding wheel to move closer to the camshaft. After moving a preset distance, the grinding mechanism is controlled to perform the grinding feed. Since the dimensions of each camshaft workpiece inevitably differ before processing, in order to avoid collisions between the camshaft and the grinding wheel, the preset distance is usually set to the maximum preset distance (i.e., grinding feed begins when there is still a considerable distance from the camshaft). Consequently, this results in a longer idle time for the grinding wheel, affecting processing efficiency. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an intelligent control system and grinding device for camshaft grinding, which solves the problem that the grinding wheel idle time is too long in the prior art, affecting the processing efficiency.

[0005] The present invention solves the above-mentioned technical problems through the following technical means:

[0006] In a first aspect, an intelligent control system for camshaft grinding includes:

[0007] Clamping unit, used to clamp and rotate the camshaft to be processed;

[0008] The detection unit is used to detect the maximum grinding radius of the cam to be ground;

[0009] The grinding unit is used to grind the cam to be ground.

[0010] The moving unit is used to control the movement of the grinding unit;

[0011] The central control unit is used to control the grinding unit to perform feed grinding according to the maximum grinding radius.

[0012] By setting up the above structure, the central control unit controls the grinding unit to perform feed grinding according to the maximum grinding radius, which can minimize the idle time of the grinding unit and avoid collision between the cam and the grinding wheel, thereby effectively improving processing efficiency while ensuring safe production.

[0013] Furthermore, it also includes a switching unit, which is signal-connected to the central control unit. When the detection unit triggers the switching unit, the switching unit controls the grinding unit to perform feed grinding through the central control unit.

[0014] Secondly, a camshaft grinding apparatus using the intelligent control system for camshaft grinding described in the first aspect includes a base and a clamping mechanism, a grinding mechanism, a moving mechanism, a detection mechanism, and a control host mounted on the base.

[0015] The clamping mechanism is used to clamp and rotate the camshaft to be processed;

[0016] The detection mechanism is used to detect the maximum grinding radius of the cam to be ground.

[0017] The grinding mechanism is used to grind the cam to be ground.

[0018] The moving mechanism is used to control the movement of the grinding unit;

[0019] The control host is used to control the grinding unit to perform feed grinding according to the maximum grinding radius.

[0020] By setting up the above structure, the host control unit controls the grinding mechanism to perform feed grinding according to the maximum grinding radius, which can minimize the idle time of the grinding unit and avoid collision between the cam and the grinding wheel, thereby effectively improving processing efficiency while ensuring safe production.

[0021] Furthermore, the detection mechanism includes a mounting base and a ranging component that is unidirectionally slidably mounted on the mounting base. A switching mechanism is mounted on the grinding mechanism. The switching mechanism is electrically connected to the control host. The horizontal distance between the switching mechanism and the ranging component is greater than the horizontal distance between the outer circle of the grinding wheel of the grinding mechanism and the ranging component. The ranging component abuts against the cam to be ground. When the clamping mechanism drives the camshaft to be processed to rotate, the rotation of the cam to be ground pushes the ranging component to move unidirectionally. The moving mechanism drives the grinding mechanism and the switching mechanism to move. When the switching mechanism is connected to the ranging component, the switching mechanism controls the grinding mechanism to perform feed grinding through the control host.

[0022] By setting up the above structure, when the clamping mechanism drives the camshaft to be processed to rotate, the rotation of the cam to be ground pushes the ranging component to move in one direction, thus measuring the maximum grinding radius of the cam to be ground. When the switching mechanism is connected to the ranging component, the switching mechanism controls the grinding mechanism to perform feed grinding through the control host. No complex signal processing and data interpretation process is required, making the control logic simpler.

[0023] Furthermore, the detection mechanism also includes a calibration component and a transmission component. The ranging component is located on the side of the cam to be ground away from the grinding mechanism, and the calibration component is located below the cam to be ground and close to the grinding mechanism. When the ranging component moves in one direction, it drives the calibration component to move through the transmission component. The distance from the calibration component to the axis of the cam shaft to be processed is the same as the distance from the ranging component to the axis of the cam shaft to be processed. When the switching mechanism is connected to the calibration component, the switching mechanism controls the grinding mechanism to perform feed grinding through the control host.

[0024] By setting the above structure, the ranging component is placed on the side of the cam to be ground away from the grinding mechanism, and connected to the switching mechanism through the calibration component, so as to avoid the ranging component affecting the grinding mechanism to feed the cam to be ground.

[0025] Furthermore, it also includes an unlocking component, and a one-way limiting component is installed on the mounting base. The one-way limiting component is used to restrict the one-way movement of the ranging component. A reset component is provided between the ranging component and the mounting base. When the unlocking component releases the one-way limiting component from restricting the ranging component in one direction, the reset component resets the ranging component.

[0026] By setting the above structure, when the unlocking component releases the one-way limit component from the one-way limit component on the ranging component, the reset component resets the ranging component so as to measure the maximum grinding radius of the next camshaft to be processed, without the need for manual reset.

[0027] Furthermore, the unlocking component includes an unlocking plate, which is fixedly connected to the grinding mechanism. The unlocking plate has an unlocking groove, and the mounting base has a sliding groove. The unlocking plate can slide into the sliding groove. The mounting base has a first mounting groove, which communicates with the sliding groove. The one-way limiting component is slidably installed in the first mounting groove. During the movement of the unlocking plate driven by the grinding mechanism, the one-way limiting component can enter and exit the unlocking groove. When the one-way limiting component enters the unlocking groove, the one-way limiting component releases the one-way limiting of the ranging component.

[0028] By setting up the above structure, the grinding mechanism drives the unlocking plate to move. When the one-way limit component enters the unlocking slot, the one-way limit component releases its one-way limit on the ranging component. This achieves automatic unlocking without the need for additional drive control of the unlocking component.

[0029] Furthermore, a support plate is slidably disposed in the unlocking groove. The support plate is located on the side close to the grinding mechanism. An elastic element is disposed between the support plate and the unlocking plate. A friction pad is disposed on the support plate. When the unlocking plate moves away from the camshaft to be processed, the one-way limiting component drives the support plate to move through the friction pad, thereby preventing the one-way limiting component from releasing the one-way limiting of the ranging component.

[0030] By setting the above structure, when the unlocking plate moves away from the camshaft to be processed, the one-way limit component drives the support plate to move through the friction pad, preventing the one-way limit component from releasing the one-way limit on the ranging component, preventing the ranging component from resetting, and preventing the ranging component from affecting the installation of the next camshaft to be processed.

[0031] Furthermore, the grinding mechanism is provided with a movable component, the mounting base is slidably mounted on the machine base, and the grinding mechanism is connected to the mounting base in a transmission manner. When the grinding mechanism starts to feed grinding, the movable component pushes the ranging component to move away from the camshaft to be processed. When the movable mechanism drives the grinding mechanism to move along the axial direction of the camshaft to be processed, the mounting plate drives the mounting base to move along the axial direction of the camshaft to be processed.

[0032] By setting up the above structure, when the moving mechanism drives the grinding mechanism to move along the axial direction of the camshaft to be processed, the mounting plate drives the mounting seat to move along the axial direction of the camshaft to be processed, eliminating the need to set up a detection mechanism for each cam to be ground. When the grinding mechanism starts to feed, the moving component pushes the ranging component to move away from the camshaft to be processed. On the one hand, this avoids the ranging component from affecting the feed grinding of the grinding mechanism; on the other hand, it prevents the ranging component from being blocked by other cams to be ground during the movement of the detection mechanism along the axial direction of the camshaft to be processed.

[0033] Furthermore, a connecting plate is fixedly provided on the side of the grinding mechanism near the cam to be processed. The connecting plate is slidably inserted into the slide groove. A second mounting groove is provided on the connecting plate. The unlocking plate is fixedly installed in the second mounting groove. The moving part includes a moving block. The moving block is fixedly installed on the connecting plate. A through groove is provided on the mounting base. When the moving block moves, the moving block can pass through the through groove to push the ranging component to move.

[0034] By setting the above structure, the transmission connection between the grinding mechanism and the mounting base is realized. When the connecting plate moves, it can drive the limit block to move, without the need to set an additional drive for the moving parts.

[0035] The beneficial effects of this invention are:

[0036] 1. This invention sets up a detection unit. After the detection unit detects the maximum grinding radius of the cam to be ground, the central control unit controls the grinding unit to perform feed grinding according to the maximum grinding radius. This can minimize the idle time of the grinding unit and avoid collision between the cam and the grinding wheel. This effectively improves processing efficiency while ensuring safe production.

[0037] 2. This invention, by setting up a switching mechanism and a ranging component, allows the maximum grinding radius of the cam to be ground to be measured when the clamping mechanism drives the camshaft to be processed to rotate. The rotation of the cam pushes the ranging component to move unidirectionally. When the switching mechanism is connected to the ranging component, the switching mechanism controls the grinding mechanism to perform feed grinding through the control host. This eliminates the need for complex signal processing and data interpretation, resulting in simpler control logic.

[0038] 3. By setting a calibration component and a transmission component, the present invention places the ranging component on the side of the cam to be ground away from the grinding mechanism, and connects it to the switching mechanism through the calibration component, thereby avoiding the ranging component from affecting the grinding mechanism to feed and grind the cam to be ground.

[0039] 4. The present invention provides an unlocking component, a one-way limiting component, and a reset component. The unlocking component releases the one-way limiting component from the ranging component, and the reset component resets the ranging component so as to measure the maximum grinding radius of the next camshaft to be processed without manual reset.

[0040] 5. By setting a support plate and an elastic element, when the unlocking plate moves away from the camshaft to be processed, the one-way limiting component drives the support plate to move through the friction pad, preventing the one-way limiting component from releasing the one-way limiting of the ranging component, preventing the ranging component from resetting, and preventing the ranging component from affecting the installation of the next camshaft to be processed.

[0041] 6. This invention connects the grinding mechanism to the mounting base via a transmission mechanism. When the moving mechanism drives the grinding mechanism to move axially along the camshaft to be processed, the mounting plate drives the mounting base to move axially along the camshaft to be processed, eliminating the need for a detection mechanism for each cam to be ground. By setting up a moving component, when the grinding mechanism starts feeding, the moving component pushes the ranging component to move away from the camshaft to be processed. On the one hand, this avoids the ranging component from affecting the feeding of the grinding mechanism; on the other hand, it prevents the ranging component from being blocked by other cams to be ground during the axial movement of the detection mechanism along the camshaft to be processed.

[0062] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0063] Example 1:

[0064] like Figure 1 As shown, this embodiment provides an intelligent control system for camshaft grinding, including:

[0065] Clamping unit, used to clamp and rotate the camshaft to be processed;

[0066] The detection unit is used to detect the maximum grinding radius of the cam to be ground;

[0067] The grinding unit is used to grind the cam to be ground.

[0068] The moving unit is used to control the movement of the grinding unit;

[0069] The central control unit is used to control the feed grinding of the grinding unit according to the maximum grinding radius.

[0070] During operation, the central control unit controls the grinding unit to feed and grind according to the maximum grinding radius. This can minimize the idling time of the grinding unit and avoid collisions between the cam and the grinding wheel, thus effectively improving processing efficiency while ensuring safe production.

[0071] It also includes a switching unit, which is connected to the central control unit via a signal. When the detection unit triggers the switching unit, the switching unit controls the grinding unit to perform feed grinding through the central control unit.

[0072] By setting up a switching unit, the detection unit can use a mechanical structure for detection, eliminating the need for sensor detection, complex signal processing and data interpretation, and making the control logic simpler.

[0073] Example 2:

[0074] like Figures 2-11 As shown, this embodiment provides a camshaft grinding device, using the camshaft grinding intelligent control system of Embodiment 1, including a base 1 and a clamping mechanism 11, a grinding mechanism 12, a moving mechanism 13, a detection mechanism 15, and a control host mounted on the base 1.

[0075] The clamping mechanism 11 is used to clamp and rotate the camshaft 14 to be processed;

[0076] The testing mechanism 15 is used to test the maximum grinding radius of the cam 141 to be ground;

[0077] The grinding mechanism 12 is used to grind the cam 141 to be ground;

[0078] The moving mechanism 13 is used to control the movement of the grinding unit;

[0079] The control host is used to control the feed grinding of the grinding unit according to the maximum grinding radius.

[0080] Since the existing technologies of clamping mechanism 11, grinding mechanism 12, and moving mechanism 13 are fully disclosed, they will not be described in detail here. During operation, the host control unit controls the grinding mechanism 12 to perform feed grinding according to the maximum grinding radius. This can minimize the idling time of the grinding unit and avoid collisions between the cam and the grinding wheel, thereby effectively improving processing efficiency while ensuring safe production.

[0081] In this embodiment, the detection mechanism 15 includes a mounting base 2 and a ranging component that is unidirectionally slidably mounted on the mounting base 2. Specifically, the ranging component includes a ranging vertical plate 3, which abuts against the cam 141 to be ground. A slider 31 is fixedly connected to the bottom of the ranging vertical plate 3, and the slider 31 is slidably mounted on the mounting base 2. A switching mechanism is installed on the grinding mechanism 12. Specifically, the switching mechanism is a photoelectric sensor 121, which is electrically connected to the control host. In some other embodiments, the switching mechanism may not be necessary, and the detection mechanism 15 may be configured as a ranging sensor, pressure sensor, etc., to measure the maximum grinding radius of the cam 141 to be ground. In this embodiment, by setting the ranging component, when the clamping mechanism 11 drives the camshaft 14 to be processed to rotate, the rotation of the cam 141 to be ground pushes the ranging component to move unidirectionally, thereby measuring the maximum grinding radius of the cam 141 to be ground. The moving mechanism 13 drives the grinding mechanism 12 and the photoelectric sensor 121 to move. When the photoelectric sensor 121 is connected to the ranging vertical plate 3, the switching mechanism controls the grinding mechanism 12 to perform feed grinding through the control host. There is no need for complicated signal processing and data interpretation process, and the control logic is simpler.

[0082] In this embodiment, the horizontal distance between the photoelectric sensor 121 and the measuring vertical plate 3 is greater than the horizontal distance between the outer circle of the grinding wheel of the grinding mechanism 12 and the measuring vertical plate 3, so as to ensure that the feed grinding is performed before the outer circle of the grinding wheel of the grinding mechanism 12 contacts the cam 141 to be ground.

[0083] It should be noted that the clamping mechanism 11 includes a clamping component and a rotating component. The clamping component is used to clamp the camshaft 14 to be processed, and the rotating component is used to rotate the camshaft 14 to be processed, thereby driving the cam 141 to be ground to rotate, so that the distance measuring component can measure the maximum grinding radius of the cam 141 to be ground. The prior art of the clamping component and the rotating component is fully disclosed, so it will not be described in detail here.

[0084] In this embodiment, the detection mechanism 15 further includes a calibration component and a transmission component. The ranging component is located on the side of the cam 141 to be ground away from the grinding mechanism 12, and the calibration component is located below the cam 141 to be ground and close to the grinding mechanism 12. When the ranging vertical plate 3 moves in one direction, it drives the calibration component to move through the transmission component. The distance from the calibration component to the axis of the cam shaft 14 to be processed is the same as the distance from the ranging component to the axis of the cam shaft 14 to be processed. Specifically, the calibration component includes a moving bar 41, and the transmission component includes a transmission gear 42. The transmission gear 42 is rotatably mounted on the mounting base 2, and the moving bar 41 is slidably mounted on the side of the mounting base 2. The bottom of the slider 31 meshes with the upper end of the transmission gear 42, and the top of the moving bar 41 meshes with the lower end of the transmission gear 42. When the photoelectric sensor 121 is in contact with the moving bar 41 (i.e., when the photoelectric sensor 121 is blocked by the moving bar 41), the photoelectric sensor 121 controls the grinding mechanism 12 to perform feed grinding through the control host. This can prevent the measuring vertical plate 3 from affecting the grinding mechanism 12's feed grinding of the grinding cam 141. In some other embodiments, it is also possible to eliminate the need for calibration and transmission components and directly provide a shrinking structure for the measuring vertical plate 3. By shrinking the measuring vertical plate 3, it can be prevented from affecting the grinding mechanism 12's grinding.

[0085] In this embodiment, an unlocking component is also included. A one-way limiting component is installed on the mounting base 2 to restrict the one-way movement of the ranging component. A reset component is provided between the ranging vertical plate 3 and the mounting base 2. When the unlocking component releases the one-way limiting component from the ranging component, the reset component resets the ranging component so as to measure the maximum grinding radius of the next camshaft 14 to be processed without manual reset. The reset component includes a reset plate 51, which is fixedly connected to the ranging vertical plate 3. A reset groove 21 is provided on the mounting base 2. The reset plate 51 is slidably disposed in the reset groove 21. Reset rods 511 are provided on both sides of the reset plate 51. A reset spring 512 is sleeved on the reset rod 511. One end of the reset spring 512 abuts against the reset plate 51, and the other end abuts against the inner end wall of the reset groove 21, so that the ranging vertical plate 3 has a tendency to move closer to the cam 141 to be ground.

[0086] In this embodiment, the unlocking component includes an unlocking plate 6, which is fixedly connected to the grinding mechanism 12. The unlocking plate 6 has an unlocking groove 61, and the mounting base 2 has a sliding groove 22. The unlocking plate 6 can slide into the sliding groove 22. The mounting base 2 has a first mounting groove 23, which communicates with the sliding groove 22. The one-way limiting component is slidably installed in the first mounting groove 23. In other embodiments, the unlocking component may not be necessary; only an independent drive for the one-way limiting component is required. In this embodiment, during the movement of the unlocking plate 6 driven by the grinding mechanism 12, the one-way limiting component can enter and exit the unlocking groove 61. When the one-way limiting component enters the unlocking groove 61, it releases the one-way limit on the reset plate 51, achieving automatic unlocking without the need for additional drive control of the unlocking component. The one-way limiting component includes a one-way limiting block 52 and a mounting box 53. The first mounting groove 23 is connected to the reset groove 21. The one-way limiting block 52 is slidably installed in the mounting box 53 by a limiting spring 521. The limiting spring 521 causes the end of the one-way limiting block 52 to protrude from the top of the mounting box 53. The end of the one-way limiting block 52 is provided with a plurality of one-way limiting teeth 522. The bottom of the reset plate 51 is provided with a rack 513. When the reset plate 51 moves away from the cam 141 to be ground, the plurality of one-way limiting teeth 522 abut against the rack 513 to prevent the reset plate 51 from moving back.

[0087] In this embodiment, a support plate 62 is slidably disposed within the unlocking groove 61. The support plate 62 is located on the side closer to the grinding mechanism 12. An elastic element, namely a support spring 621, is disposed between the support plate 62 and the unlocking plate 6. A friction pad 622 is disposed on the support plate 62. When the unlocking plate 6 moves away from the camshaft 14 to be processed, the one-way limiting component drives the support plate 62 to move through the friction pad 622, preventing the one-way limiting component from releasing the one-way limiting of the measuring vertical plate 3, preventing the measuring vertical plate 3 from resetting, and preventing the measuring vertical plate 3 from affecting the installation of the next camshaft 14 to be processed. In some other embodiments, the support plate 62 may not be necessary; it is sufficient to force the measuring vertical plate 3 to move by making the camshaft 14 to be processed.

[0088] In this embodiment, the mounting base 2 is slidably mounted on the machine base 1, and the grinding mechanism 12 is connected to the mounting base 2 via a transmission. When the moving mechanism 13 drives the grinding mechanism 12 to move along the axial direction of the camshaft 14 to be processed, the mounting plate drives the mounting base 2 to move along the axial direction of the camshaft 14 to be processed. Only one detection mechanism 15 is needed to detect the cams 141 to be ground on the entire camshaft 14 to be processed. The grinding mechanism 12 is provided with a moving part. When the grinding mechanism 12 starts to feed grinding, the moving part pushes the measuring vertical plate 3 to move away from the camshaft 14 to be processed. On the one hand, this avoids the measuring vertical plate 3 from affecting the grinding feed of the grinding mechanism 12. On the other hand, it prevents the measuring vertical plate 3 from being blocked by the other cams 141 to be ground during the movement of the detection mechanism 15 along the axial direction of the camshaft 14 to be processed. If no moving parts are provided, when the maximum grinding radius of an adjacent cam 141 to be ground is greater than the maximum grinding radius of the previous cam, the measuring vertical plate 3 will not be able to move smoothly along the axial direction of the camshaft 14 to be processed.

[0089] In this embodiment, a connecting plate 7 is fixedly installed on the side of the grinding mechanism 12 near the cam to be processed. The photoelectric sensor 121 is fixedly installed on the connecting plate 7. The connecting plate 7 is slidably inserted into the slide groove 22. When the grinding mechanism 12 moves along the axial direction of the camshaft 14 to be processed, the mounting seat 2 is driven to move along the axial direction of the camshaft 14 to be processed through the connecting plate 7, thereby realizing the transmission connection between the grinding mechanism 12 and the mounting seat 2. A second mounting groove 71 is provided on the connecting plate 7. The unlocking plate 6 is fixedly installed in the second mounting groove 71. The moving part includes a moving block 8, which is fixedly installed on the connecting plate 7. A through groove 24 is provided on the mounting seat 2. It should be noted that since the dimensional differences between the cams 141 to be ground generally do not exceed the difference between the standard maximum grinding radius and the standard minimum grinding radius, setting the horizontal distance between the center of the moving block 8 and the axis of the camshaft 14 to be processed as the standard maximum grinding radius, and setting the horizontal distance between the center of the moving block 8 and the outer circle of the grinding wheel of the grinding mechanism 12 as twice the standard maximum grinding radius, ensures that the moving block 8 can push the measuring vertical plate 3 to move away from the camshaft 14 to be processed. In some other embodiments, the moving component can also be set as a drive cylinder, which drives the measuring vertical plate 3 to move away from the cam 141 to be ground. An independent drive is set for the mounting base 2 to control the mounting base 2 to move synchronously with the grinding mechanism 12. In this embodiment, by setting the connecting plate 7 and the moving block 8, when the moving block 8 moves, the moving block 8 can pass through the through slot 24 to push the measuring vertical plate 3 to move. When the connecting plate 7 moves, it can drive the moving block 8 to move, without the need to set an additional drive for the moving component and the mounting base 2.

[0090] The working principle of this invention is as follows:

[0091] First, the camshaft 14 to be processed is clamped by the clamping assembly.

[0092] Then, the control host controls the grinding mechanism 12 to move closer to the camshaft 14 to be processed through the moving mechanism 13. During the movement of the grinding mechanism 12, the connecting plate 7 drives the unlocking plate 6 to move.

[0093] When the unlocking slot 61 moves below the one-way limiting component, and the mounting box 53 of the one-way limiting component enters the unlocking slot 61, the mounting box 53 drives the one-way limiting block 52 to move downward, causing the one-way limiting block 52 to release its one-way limiting effect on the reset plate 51. Under the elastic action of the reset spring 512, the reset plate 51 drives the measuring vertical plate 3 to move closer to the cam 141 to be ground, until the measuring vertical plate 3 abuts against the cam 141 to be ground.

[0094] When the support plate 62 comes into contact with the mounting box 53, the support plate 62 pushes the mounting box 53 upward, causing the one-way limit block 52 to once again limit the reset plate 51 in one direction.

[0095] Subsequently, the rotating component operates, causing the camshaft 14 to be processed to rotate one revolution, thereby causing the cam 141 to be ground to rotate one revolution. The rotation of the cam 141 pushes the measuring vertical plate 3 to move away from the cam 141 to be ground. When the measuring vertical plate 3 moves, it drives the moving bar 41 to move through the transmission gear 42 until the measuring vertical plate 3 moves to the maximum grinding radius of the cam 141 to be ground.

[0096] When the photoelectric sensor 121 is in contact with the moving bar 41 (i.e., when the photoelectric sensor 121 is blocked by the moving bar 41), the photoelectric sensor 121 controls the grinding mechanism 12 to perform feed grinding through the control host.

[0097] When the moving block 8 passes through the through slot 24 and comes into contact with the measuring vertical plate 3, the moving block 8 pushes the measuring vertical plate 3 to move away from the grinding cam 141.

[0098] After the grinding of the cam 141 is completed, the grinding mechanism 12 moves away from the camshaft 14 to be processed. During this process, the grinding mechanism 12 drives the unlocking plate 6 to move away from the camshaft 14 to be processed through the connecting plate 7. When the support plate 62 is in contact with the bottom surface of the mounting box 53, the mounting box 53 drives the support plate 62 to move against the elastic force of the support spring 621 through the friction pad 622. When the support plate 62 abuts against the end wall of the unlocking groove 61, the support plate 62 forcibly passes through the mounting box 53. At the same time, the mounting box 53 transitions to the unlocking plate 6 and is supported by the unlocking plate 6. The support spring 621 resets the support plate 62.

[0099] Finally, the moving mechanism 13 operates, driving the grinding mechanism 12 and the detection mechanism 15 to move along the axial direction of the camshaft 14 to be processed, so as to grind the next camshaft 141 to be ground.
