Description

Technical Field

[0001] This invention relates to the field of cam grinding technology, specifically a cam surface fine treatment device. Background Technology

[0002] A cam is a key component in mechanical engineering. Its core characteristic is that it has a specific profile curve or groove, and drives a follower in contact with it through rotational or linear motion to achieve precise reciprocating, oscillating, or lifting motion. Its design must meet the requirements of output kinematics and dynamics, and it is the driving component of a higher pair mechanism. The profile accuracy and surface quality of the cam are crucial to its performance. Grinding is the core process in cam finishing.

[0003] When treating the surface of a cam, it is usually done directly by using a grinding belt. However, when the cam surface has a concave structure, the grinding belt cannot contact the concave part of the cam. Therefore, it cannot be adapted to the grinding treatment of cams with different structures, nor can it be used to grind the corner parts of the cam. As a result, it is impossible to guarantee the smooth operation of the cam, the noise level, the fatigue life, and the life of the follower. Therefore, it is necessary to improve the treatment.

[0031] The position adjustment frame mechanism 2 includes a first fixing plate 201 fixed on the placement base 1. There are two first fixing plates 201, and a first threaded rod 202 is rotatably connected between the two first fixing plates 201.

The fixed slide rod 206 passes through the movable adjustment frame 204, and the fixed slide rod 206 and the movable adjustment frame 204 are slidably connected.

[0032] Specifically, when the first motor 203 is turned on, the output shaft of the first motor 203 rotates, which drives the first threaded rod 202 to rotate, thereby driving the movable adjustment frame 204 to move along the axis of the fixed slide rod 206.

[0033] The grinding belt mechanism 3 includes two first linear motors 301 fixed on a movable adjustment frame 204.

[0034] Specifically, activating the first linear motor 301 drives the lifting wheel frame 302 and the lifting wheel 303 to rise and fall, thereby adjusting the lower height of the grinding belt 309 so that the grinding belt 309 fits snugly against the surface of the cam. Simultaneously, activating the second linear motor 304 drives the tensioning mechanism 305 to rise and fall, which in turn drives the drive wheel frame 306 and the drive wheel 308 to rise and fall. Due to the presence of the tensioning mechanism 305, the tension of the grinding belt 309 is ensured. At this time, activating the second motor 307 causes the output shaft of the second motor 307 to rotate, which in turn drives the drive wheel 308 to rotate.

The torsion sleeve 9024 is rotatably connected to the reset seat 9021. The torsion sleeve 9024 is fixedly connected to a fixed slide frame 903. The rotary drive mechanism 10 includes a fixed housing 1001 fixed on a fixed side plate 8. A fifth motor 1002 is provided on the fixed housing 1001. The output shaft of the fifth motor 1002 is fixedly connected to a second rotating shaft 1003. The second rotating shaft 1003 is fixedly connected to a first friction clutch plate 1004. The fixed housing 1001 is fixedly connected to a fifth linear motor 1005. The end of the fifth linear motor 1005 is fixedly connected to a displacement ring 1006. The displacement ring 1006 is rotatably connected to a second friction clutch plate 1007. The first friction clutch plate 1004 and the second friction clutch plate 1007 are arranged coaxially. The second friction clutch plate 1007 is fixedly connected to a third rotating shaft 1008. The third rotating shaft 1008 and the first rotating shaft 1001 are coaxially fixedly connected.

[0036] Specifically, firstly, one end of the cam is inserted into the second fixed housing 906. At this time, the second rotating handle 908 is rotated, which drives the fourth threaded rod 907 to rotate, thereby driving the second arc-shaped clamping plate 909 to feed, so as to achieve the centering and clamping of the cam. Then, the third motor 503 is turned on, which drives the second threaded rod 502 to rotate, thereby driving the moving side plate 504 to move along the axis of the second threaded rod 502, thereby driving the deflection ball shaft 601 and the first mounting shaft 701, thereby driving the first fixed housing 702 to feed. The other end of the cam is placed in the first fixed housing 702, so that the cam abuts in the first concave groove 703. At this time, the first rotating handle 705 is rotated, which drives the third threaded rod 704 to rotate, thereby driving the first arc-shaped clamping plate 706 to feed, so as to achieve the centering and clamping of the cam.

[0037] Alternatively, if cam deflection is required, the fifth linear motor 1005 is activated, thereby driving the displacement ring 1006 and the second friction clutch plate 1007 to shift, causing the second friction clutch plate 1007 to disengage from the first friction clutch plate 1004. At this time, the fourth motor 603 is activated, and the rotation of the output shaft of the fourth motor 603 will drive the first gear 604 to rotate. The rotation of the first gear 604 will drive the second gear 606 to rotate, thereby causing the displacement ring 605 to rotate, which will drive the fourth linear motor 609 to rotate and shift around the deflection shaft 602. When the fourth linear motor 609 rotates to the specified angle, it is activated, thereby driving the deflection shaft 602 and the deflection ball shaft 601 to deflect, which in turn drives the cam to deflect. At this time, the edges and corners of the cam can be ground.

[0038] In an embodiment of the present invention, if the cam needs to rotate and change position, the fifth linear motor 1005 is turned on, thereby driving the displacement ring 1006 and the second friction clutch plate 1007 to change position, so that the second friction clutch plate 1007 and the first friction clutch plate 1004 come into contact. At this time, the fifth motor 1002 is turned on, and the output shaft of the fifth motor 1002 rotates, which drives the second rotating shaft 1003. The rotation of the second rotating shaft 1003 drives the first friction clutch plate 1004, and the rotation of the first friction clutch plate 1004 drives the second friction clutch plate 1007 to rotate, which in turn drives the third rotating shaft 1008 to rotate. At this time, the first rotating shaft 901 rotates, and the rotation of the first rotating shaft 901 drives the reset seat mechanism 902 to rotate, which in turn causes the fixed slide frame 903 and the magnetic slider 904 to rotate, thereby driving the second mounting shaft 905 and the second fixed shell 906 to rotate, so as to drive the cam to rotate and change position.

[0039] Example 2, see below. Figures 1-3 In this embodiment of the invention, the feeding top wheel mechanism 4 includes a third linear motor 401 fixed on the movable adjustment frame 204, the bottom of the third linear motor 401 is fixedly connected to the top wheel frame 402, and the top wheel frame 402 is rotatably connected to the top wheel 403.

[0040] Specifically, turning on the third linear motor 401 can drive the top wheel frame 402 and the top wheel 403 to feed. The top wheel 403 can push the grinding belt 309, so that the grinding belt 309 contacts the cam, thus realizing the grinding treatment of the concave position on the cam.

[0041] In the implementation of this invention, firstly, one end of the cam to be polished is fixed on the deflection fixing mechanism 9. Then, the moving side plate mechanism 5 is adjusted to adjust the position of the end fixing mechanism 7, thereby clamping and fixing the other end of the cam. Next, the position adjusting bracket mechanism 2 is activated to laterally adjust the position of the polishing belt mechanism 3, thus adjusting the polishing belt mechanism 3 to the position where the cam needs polishing. Then, the polishing belt mechanism 3 is activated to perform enveloping polishing on the cam. If the cam has a concave structure, the feed top wheel mechanism 4 is activated to push the polishing belt mechanism 3. This allows for direct contact grinding of the concave portion of the cam. If grinding is required on different circumferential positions of the cam, the rotary drive mechanism 10 is activated. The rotary drive mechanism 10 drives the deflection fixing mechanism 9 to rotate, which in turn drives the cam to rotate, thus allowing grinding on different circumferential positions of the cam. If grinding is required on the corners of the cam, the drive of the rotary drive mechanism 10 is disconnected, and the deflection positioning mechanism 6 is activated, causing the cam to deflect. At this time, the grinding belt mechanism 3 is activated to grind the corners of the cam, thereby achieving fine processing of the cam surface.

[0042] This invention enables the lateral displacement of the grinding belt mechanism 3 by setting a position adjustment frame mechanism 2, thereby grinding and fixing different lateral positions of the cam. The feed top wheel mechanism 4 can perform local grinding on the concave area of ​​the cam. The moving side plate mechanism 5 can drive the end fixing mechanism 7 to move, and together with the deflection fixing mechanism 9, it can clamp and fix cams of different lengths and sizes. The deflection positioning mechanism 6 can adjust the deflection angle of the end fixing mechanism 7, and together with the grinding belt mechanism 3, it can grind the edges and corners of the cam. The rotation drive mechanism 10 can drive the cam to rotate and move, thereby grinding different circumferential positions of the cam. The grinding belt mechanism 3 can perform a covering grinding treatment on the cam, enriching the performance of cam surface treatment.
