DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0021] See also Figures 1 to 4 A grinding device for automobile transmission shaft processing, the grinding device for automobile transmission shaft processing includes: a bracket 1, a cover 2, a rotating plate 3, a rubber roller 4, a guide rod 5, a grinding wheel grinder 6, an intermittent rotation mechanism 7 and a driving rotation mechanism 8. A cover shell 2 is symmetrically fixedly connected to the top of the bracket 1, a notch is provided on the outer side of the cover shell 2, a rotating shaft 9 is rotatably connected between the cover shells 2, a rotating plate 3 is symmetrically fixedly connected to the outer sides of both ends of the rotating shaft 9, grooves are equidistantly provided on the outer side of the rotating plate 3, an embryo transmission shaft 10 is equidistantly provided on the outer side of the rotating shaft 9, both ends of the embryo transmission shaft 10 are respectively embedded in the corresponding grooves of the two rotating plates 3, both ends of the transmission shaft are arranged inside the corresponding cover shell 2, rubber rollers 4 are provided on the outer sides of both ends of the embryo transmission shaft 10, and the rubber rollers 4 are rotatably connected between the corresponding rotating plates 3, the rubber rollers 4 are in extrusion contact with the corresponding embryo transmission shaft 10, a guide rod 5 is fixedly connected between the cover shells 2, a grinding wheel grinder 6 is provided on one side of the bracket 1, a connecting piece 11 is fixedly connected to one side of the grinding wheel grinder 6, and the connecting piece 11 is slidably connected to the outer side of the guide rod 5, an intermittent rotation mechanism 7 is installed on the outer side of the cover shell 2 on one side of the top of the bracket 1, and a driving rotation mechanism 8 is installed on the outer side of the cover shell 2 on the other side of the top of the bracket 1

[0022] It should be noted that the original embryo drive shaft 10 is evenly distributed on the rotating shaft 9 and is kept stable by the groove of the rotating plate 3. Once the intermittent rotation mechanism 7 is started, it will use the interaction between the tripod 13 and the rotating plate 15 to drive the rotating shaft 9 and the original embryo drive shaft 10 thereon to intermittently rotate and alternate positions. This design ensures that each original embryo drive shaft 10 can be moved to the grinding position of the grinding wheel grinder 6 in turn. The grinding wheel grinder 6 is arranged on one side of the device and is cleverly staggered with the notch position on the outer side of the cover shell 2. When the grinding wheel grinder 6 is grinding a certain original embryo drive shaft 10, the notch on the other side will just expose the drive shaft that has been polished, so that the operator can easily take out the finished product and immediately replace it with an unpolished original embryo drive shaft 10. This operation process does not require interrupting the grinding work, thereby significantly improving the overall work efficiency.

[0023] See also Figures 1 to 4 The intermittent rotation mechanism 7 includes a sleeve 12, a tripod 13, a rotating rod 14, a rotating plate 15 and a fixed rod 16. The sleeve 12 is fixedly connected to the outside of one end of the rotating shaft 9, and the tripod 13 is fixedly connected to the outside of the sleeve 12 at an equal distance, and the two tripods 13 on the outside of the rotating shaft 9 are staggered. The rotating rod 14 is rotatably connected to the outside of the cover 2 on one side of the top of the bracket 1, and the rotating plate 15 is fixedly connected to the outside of the rotating rod 14. A fan-shaped groove is opened on one side of the rotating plate 15, and the other side of the rotating plate 15 is embedded in the corresponding tripod 13. The fixed rod 16 is symmetrically fixedly connected to the surface of the rotating plate 15;

[0024] It should be noted that the operator drives the rotation of the rotating rod 14 and the rotating plate 15 by manually turning the hand wheel 17. When the rotating plate 15 rotates, its fan-shaped groove will be embedded in the gap between the branches of one of the tripod rods 13, and the tripod rod 13 will be kept staggered. At this time, the embedded tripod rod 13 is restricted by the rotating plate 15 and will not rotate by itself. As the rotating plate 15 continues to rotate, the fixed rod 16 on its surface will gradually approach and contact the branch of the other tripod rod 13. Once the fixed rod 16 contacts the branch of the tripod rod 13, it will drive the tripod rod 13 to start rotating. , since the fan-shaped groove of the rotating plate 15 also rotates to the branch of the tripod 13, the two tripods 13 can rotate freely at this time. Driven by the fixed rod 16, the two tripods 13 will rotate 120 degrees at the same time. This action is transmitted to the rotating shaft 9 through the sleeve 12, so that the rotating shaft 9 also rotates accordingly. Since there are three original embryo transmission shafts 10 equidistantly distributed on the rotating shaft 9, this rotation action will cause the original embryo transmission shafts 10 to alternate positions, that is, one original embryo transmission shaft 10 moves from the grinding position to the waiting grinding position, and the other original embryo transmission shaft 10 to be polished moves to the grinding position;

[0025] See also Figures 1 to 4, one end of the rotating rod 14 is fixedly connected with a hand wheel 17;

[0026] It should be noted that the operation of the intermittent rotation mechanism 7 is controlled by manually rotating the hand wheel 17;

[0027] See also Figures 1 to 4 The driving rotating mechanism 8 includes a motor 18, a driving rubber roller 19 and a transmission rubber roller 20. The motor 18 is installed on the outer side of the cover shell 2 on the other side of the top of the bracket 1. The output end of the motor 18 is fixedly connected to the driving rubber roller 19. The transmission rubber roller 20 is equidistantly connected to the rotating plate 3 on the outer side of the rotating shaft 9 close to the motor 18. One end of the transmission rubber roller 20 is fixedly connected to one end of the corresponding rubber roller 4, and the driving rubber roller 19 and the corresponding transmission rubber roller 20 are pressed and fitted with each other.

[0028] It should be noted that: as the positions of the embryo transmission shaft 10 are alternating, the corresponding transmission rubber roller 20 will also keep synchronous movement with the driving rubber roller 19 through the mechanical linkage device. When a certain embryo transmission shaft 10 moves to the grinding position, the corresponding transmission rubber roller 20 will fit closely with the driving rubber roller 19. Driven by the rotation of the driving rubber roller 19, the transmission rubber roller 20 can ensure that the embryo transmission shaft 10 rotates stably in the groove of the rotating plate 3, thereby cooperating with the grinding wheel grinder 6 to perform efficient grinding operations;

[0029] See also Figures 1 to 4 , a holding rod 21 is fixedly connected to the bottom of the grinding wheel grinder 6;

[0030] It should be noted that the holding rod 21 is used to facilitate the operator to stably control and operate the grinding wheel grinder 6 to achieve accurate grinding of the original embryo transmission shaft 10;

[0031] See also Figures 1 to 4 , the shape of the grooves equidistantly provided on the outer side of the rotating plate 3 matches the cross-sectional shape of the original embryo transmission shaft 10;

[0032] It should be noted that: to ensure that the embryo transmission shaft 10 can be stably placed and rotated on the rotating plate 3;

[0033] See also Figures 1 to 4 The tripod 13 is directly fixed to the outside of the sleeve 12 by three equal-length branches, and is evenly distributed around the sleeve 12 at equal angles, and the rotating plate 15 is embedded in the gaps between the corresponding branches of the tripod 13;

[0034] It should be noted that the intermittent rotation and alternating positions of the rotating shaft 9 and the embryo transmission shaft 10 thereon are achieved through the interaction between the branches of the tripod 13 and the rotating plate 15 .

[0035] The working principle of the grinding device for automobile transmission shaft processing provided by the utility model is as follows:

[0036] The embryo transmission shafts 10 are evenly distributed on the rotating shaft 9 and are kept stable by the grooves of the rotating plate 3. Once the intermittent rotation mechanism 7 is started, it will use the interaction between the tripod 13 and the rotating plate 15 to drive the rotating shaft 9 and the embryo transmission shafts 10 thereon to intermittently rotate and alternate positions. This design ensures that each embryo transmission shaft 10 can be moved to the grinding position of the grinding wheel grinder 6 in turn.

[0037] The grinding wheel grinder 6 is arranged on one side of the device, and is cleverly staggered with the notch position on the outer side of the cover shell 2. When the grinding wheel grinder 6 is grinding a raw embryo transmission shaft 10, the notch on the other side will just expose the grinding-finished transmission shaft, so that the operator can easily take out the finished product and immediately replace it with the ungrinded raw embryo transmission shaft 10. This operation process does not require interrupting the grinding work, thereby significantly improving the overall work efficiency;

[0038] It is worth noting that the last raw embryo transmission shaft 10 is always kept in a standby state. When the grinding of the current transmission shaft is completed, the transmission shaft can be moved to the grinding position through the intermittent rotation mechanism 7 for the next round of grinding.

[0039] In addition, the transmission rubber roller 20 plays a vital role in the whole process. As the position of the embryo transmission shaft 10 is alternating, the corresponding transmission rubber roller 20 will also keep synchronous movement with the driving rubber roller 19 through the mechanical linkage device. When a certain embryo transmission shaft 10 moves to the grinding position, the corresponding transmission rubber roller 20 will fit closely with the driving rubber roller 19. Driven by the rotation of the driving rubber roller 19, the transmission rubber roller 20 can ensure that the embryo transmission shaft 10 rotates stably in the groove of the rotating plate 3, thereby cooperating with the grinding wheel grinder 6 to perform efficient grinding operations;

[0040] During the entire grinding process, the operator only needs to manually turn the handwheel 17 to control the operation of the intermittent rotation mechanism 7 to alternate the positions of the original embryo transmission shaft 10. At the same time, the notch design on the cover 2 enables the operator to easily complete the replacement of the transmission shaft. This efficient processing flow ensures the high quality and high efficiency of automobile transmission shaft processing.
