Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a double-pass sanding machine for aluminum parts with adjustable speed, comprising a machine body 1, a feeding assembly for controlling the feeding of aluminum parts fixedly connected to the top left end of the machine body 1, the feeding assembly including a support frame 2, the support frame 2 being fixedly connected to the left end of the top wall of the machine body 1, and a sanding assembly for performing sanding operations on the aluminum parts installed inside the machine body 1, the sanding assembly including a motor 3, a first connecting rod 31 and a second connecting rod 39, the motor 3 being installed on the right end of the front side of the inner wall of the machine body 1, the motor 3... The output end is fixedly connected to the right end of the outer wall of the first connecting rod 31, and the left and right ends of the outer wall of the second connecting rod 39 are rotatably connected to the inner wall of the machine body 1. The left and right ends of the outer walls of the first connecting rod 31 and the second connecting rod 39 are fixedly connected to the first gear set 32. The feeding assembly also includes a base 21, which is fixedly connected to the top wall of the support frame 2. A vibratory plate 22 is installed on the left end of the top wall of the base 21, and a conveying plate 23 is fixedly connected to the end of the vibratory plate 22. The outer wall of the conveying plate 23 is connected to the feeding cylinder 24.

[0021] Through the above technical solution, the feeding structure is fixed by the support frame 2 and the base 21, thereby providing a stable platform for the feeding structure to be installed. The aluminum parts to be processed enter the feeding cylinder 24 through the vibrating plate 22 and the conveying plate 23. The feeding cylinder 24 and the conveying plate 23 are matched to ensure the stability of the aluminum parts feeding.

[0022] Please see Figure 1 , Figure 2 and Figure 3 The sand-rolling assembly also includes a first sand-rolling cylinder 33 and a second sand-rolling cylinder 38. The first sand-rolling cylinder 33 and the second sand-rolling cylinder 38 are respectively installed at the front and rear ends of the top inside the machine body 1. The left and right ends of the outer walls of the first sand-rolling cylinder 33 and the second sand-rolling cylinder 38 are fixedly connected to the second gear set 34. The first gear set 32 ​​and the second gear set 34 are meshed together. The middle part of the outer walls of the first sand-rolling cylinder 33 and the second sand-rolling cylinder 38 are respectively fixedly connected to the first external gear ring 37 and the second external gear ring 310. The first external gear ring 37 and the second external gear ring 310 are meshed together. The sand-rolling assembly also includes two feed ports 35. The two feed ports 35 are respectively opened at the left end of the top wall of the first sand-rolling cylinder 33 and the second sand-rolling cylinder 38. The first sand-rolling cylinder 33 and the second sand-rolling cylinder 38 are fixedly installed with feed plugs 36 at the feed ports 35 by bolts. The end of the discharge cylinder 24 is installed at the top of the feed port 35.

[0023] Through the above technical solution, sanding cylinders are installed at both the front and rear ends inside the machine body 1 to achieve double sanding, ensuring the efficiency of aluminum part processing. The motor 3 drives the first connecting rod 31 and the first sanding cylinder 33 to drive the second sanding cylinder 38 and the second connecting rod 39 to drive synchronously, so as to realize the normal operation of double sanding. The end of the feed cylinder 24 needs to correspond to the feed port 35 to ensure that the aluminum parts can enter stably.

[0024] Please see Figure 1 , Figure 3 and Figure 4 The inner walls of the first sanding cylinder 33 and the second sanding cylinder 38 are fixedly connected with white corundum abrasive 7 that contacts the aluminum parts; a cavity 6 is opened in the middle of the outer wall of the machine body 1; a discharge port 4 is opened in the outer wall of the first sanding cylinder 33 and the second sanding cylinder 38; a discharge plug 5 is fixedly installed on the top wall of the discharge port 4 of the first sanding cylinder 33 and the second sanding cylinder 38 by bolts; a control panel 8 is installed on the right side of the front end of the outer wall of the machine body 1, and the control panel 8 is electrically connected to the motor 3.

[0025] Through the above technical solution, the white fused alumina abrasive 7 has the characteristics of high hardness, good thermal stability and stable chemical properties. It is not easy to react chemically with aluminum parts, and can maintain the quality of the processed surface and the purity of the product. Therefore, the use of white fused alumina abrasive 7 can ensure the effect of tumbling aluminum parts. The size of the discharge port 4 needs to be large to facilitate the operator to take out the aluminum parts. The discharge plug 5 can be used to seal the tumbling cylinder. The control panel 8 is connected to the motor 3 to ensure the stability of the device operation.

[0026] Working principle: The support frame 2 and the base 21 are fixedly connected to the top of the machine body 1. The aluminum parts to be processed are poured into the vibratory feeder 22. The working principle of the vibratory feeder 22 is to generate high-frequency vibration through an electromagnetic vibrator, causing the hopper to vibrate in the vertical direction. The aluminum parts are subjected to vibration force in the hopper and rise along the spiral track of the hopper. During the rise, they undergo a series of orderly arrangement and screening, and are finally sent to the designated position according to the preset trajectory and speed. The aluminum parts enter the feed inlet 35 through the conveyor plate 23 and the discharge cylinder 24. The feed plug 36 is then fixed with bolts to ensure the sealing of the sand rolling cylinder. The motor 3 is started, and the motor 3 drives the first connecting rod 31 to rotate. Since the first gear set 32 ​​is fixed to the outer wall of the first connecting rod 31 and the second connecting rod 39, it cooperates with the first gear set 32 ​​and the second gear set 34. The meshing connection drives the first sanding cylinder 33 to rotate synchronously. The first sanding cylinder 33 drives the second sanding cylinder 38 to rotate synchronously through the meshing connection between the first external gear ring 37 and the second external gear ring 310. The second sanding cylinder 38 and the second connecting rod 39 are also driven by the first gear set 32 ​​and the second gear set 34. Since both ends of the second connecting rod 39 are rotatably connected to the inner wall of the machine body 1, the stability of the sanding assembly is ensured. A layer of white corundum abrasive 7 is fixedly connected to the inner wall of the sanding cylinder. The white corundum abrasive 7 contacts the aluminum part to achieve uniform grinding of the aluminum part. The speed of the motor 3 can be controlled through the control panel 8, so that the speed of the sanding cylinder can be adjusted according to the usage requirements. After the sanding is finished, the discharge plug 5 is opened, and the operator enters the discharge port 4 through the cavity 6 to take out the workpiece, which improves the convenience of use.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
