In order to solve the problem that the relative operation effect between the workpiece and the grinding disc is not good, a long grinding time is required to achieve the grinding effect, and during the grinding process, not much processing is done on the positioning of the grinding piece, and the polishing after grinding mostly needs to be re-polished, which leads to the problem of complicated processing process. By the reverse rotation of the output end between the grinding motor and the turntable motor, the tooth column turntable is driven by the grinding motor and the grinding turntable is driven by the turntable motor to rotate in the opposite direction, so as to achieve the effect of fully grinding the bearing in the bearing grinding cavity. By setting the grinding turntable to grind the bearing, the final bearing grinding end face can be made flat and smooth, and the reverse rotation between the grinding turntable and the tooth column turntable cooperates with each other, which can speed up the grinding efficiency of the bearing, and at the same time, the flatness and smoothness of the bearing grinding can be effectively improved.

DETAILED DESCRIPTION

[0022] In order to make the technical solution of the utility model more clear and specific to those skilled in the art, the utility model is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the utility model are not limited thereto.

[0023] like Figure 1-Figure 4 As shown, this embodiment provides a linkage double-sided grinding machine, including a base 1, a lower grinding disc 2 horizontally fixed on the top of the base 1, an upper grinding disc 3 located on the top of the lower grinding disc 2 and parallel to and coaxially arranged with the lower grinding disc 2, a sun gear 4 rotatably installed at the middle position of the lower grinding disc 2, an inner tooth column 6 uniformly fixed on the outer side of the top of the sun gear 4 in an annular array, and a rotary motor 5 installed on the top of the base 1 to control the rotation of the sun gear 4, and an outer tooth column 7 uniformly arranged on the outer side of the top of the lower grinding disc 2 in an annular array, and the outer tooth column 7 is perpendicular to the horizontal plane and is parallel to the lower grinding disc 2. 2 are slidingly connected, the outer side of the lower grinding disc 2 is uniformly provided with sliding holes 16 cooperating with the outer tooth column 7 along the circumferential direction, the top of the lower grinding disc 2 is uniformly provided with planetary wheels 8 meshing with the inner tooth column 6 and the outer tooth column 7, and the planetary wheels 8 are provided with part limiting holes, and the outer side of the lower grinding disc 2 is rotatably mounted with a collar 9, and the bottom of the collar 9 is fixed with a tray 10 that fits with the bottom of the lower grinding disc 2, a notch is provided on the tray 10, an arc plate 11 is provided inside the notch, and both ends of the arc plate 11 fit with the ends of the tray 10, and a lifting assembly is provided on the outer side of the arc plate 11.

[0024] The overall working principle is as follows: during use, the planetary wheel 8 is placed on the top of the lower grinding disc 2, and the tooth grooves of the planetary wheel 8 are stuck in the outer sides of the inner tooth column 6 and the outer tooth column 7. Then the workpiece is placed in the part limiting hole on the planetary wheel 8. The workpiece first contacts the bottom of the lower grinding disc 2, and then the upper grinding disc 3 is controlled to descend, and the bottom of the upper grinding disc 3 is attached to the top of the workpiece. In the process of the rotating motor 5 controlling the rotation of the sun gear 4, the planetary wheel 8 can not only rotate on itself, but also make circular motion along the sun gear 4, so the workpiece can grind both sides at the same time. When the planetary wheel 8 or the workpiece is taken and placed, the sleeve ring 9 is first rotated to change the position of the arc plate 11, and then the lifting assembly is used to move the arc plate 11 downward, and the outer tooth column 7 at the top of the arc plate 11 will move simultaneously with the arc plate 11. At this time, an unobstructed gap is formed on the outer side of the lower grinding disc 2, so the planetary wheel 8 and the workpiece can be pushed horizontally onto the lower grinding disc 2, which is more convenient in the replacement of the planetary wheel 8 and the taking and placing of the workpiece.

[0025] In this embodiment, a pick-up and placement platform 12 is horizontally fixed to the outer side of the collar 9 , and the end of the pick-up and placement platform 12 is directly opposite to the top of the arc plate 11 , and the width of the pick-up and placement platform 12 is greater than the distance between the two ends of the arc plate 11 .

[0026] Partial working principle: The presence of the pick-and-place table 12 can facilitate temporary storage of the planetary gear 8 and the workpiece, making it more convenient to use.

[0027] In this embodiment, both sides of the top of the pick-up and place platform 12 are provided with limit strips, and the top of the pick-up and place platform 12 is coated with a wear-resistant coating.

[0028] Partial working principle: When the planetary wheel 8 is pushed horizontally, it will rub against the top of the pick-up and placement table 12, so applying a wear-resistant coating can reduce the wear on the pick-up and placement table 12, and the setting of the limit strip can prevent the planetary wheel 8 or the workpiece from falling from the side.

[0029] In this embodiment, the lifting mechanism includes a limit plate 13 and a spring 14 . The limit plate 13 is horizontally fixed on the outer side of the arc plate 11 , and the limit plate 13 is located below the placement platform 12 . The spring 14 is installed between the placement platform 12 and the limit plate 13 .

[0030] Local working principle: when controlling the arc plate 11 to move downward, the limit plate 13 is pulled downward, and the arc plate 11 moves downward together with the limit plate 13. When the downward moving length of the limit plate 13 is the same as the length of the outer tooth column 7 protruding from the lower grinding disc 2, stop pulling down. At this time, there is an unobstructed gap on the side of the lower grinding disc 2.

[0031] In this embodiment, a slide rod 15 is vertically fixed to the bottom end of the pick-up and placement platform 12 , the slide rod 15 passes through the limit plate 13 and is slidably connected to the limit plate 13 , and an anti-slip block is fixed to the bottom end of the slide rod 15 .

[0032] Partial working principle: in the process of controlling the limit plate 13 to move downward, the setting of the slide rod 15 can ensure the vertical downward movement of the limit plate 13, and the setting of the anti-detachment block can limit the maximum downward movement length of the limit plate 13 to prevent the limit plate 13 from detaching.

[0033] In this embodiment, a handle is provided at one end of the bottom of the limiting plate 13 away from the arc-shaped plate 11, and the handle is in a U-shape.

[0034] Partial working principle: During use, the downward movement of the limit plate 13 can be conveniently controlled by setting the handle, and the operation is more convenient.

[0035] In this embodiment, a magnet block is provided at the joint between the top of the arc plate 11 and the bottom end of the outer tooth column 7, and a limit block is provided at the bottom end of the outer tooth column 7.

[0036] Partial working principle: The magnet block can be adsorbed on the bottom end of the outer tooth column 7 to ensure that the outer tooth column 7 can move downward quickly following the arc plate 11.

[0037] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
