Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical component coating, in particular to a differential device for controlling a fixture turntable in a coating cavity. Background Art

[0002] During the machining of mechanical components, it is necessary to coat the inner cavity to improve the wear resistance and corrosion resistance of the workpiece;

[0003] In current coating spraying technology, a common practice is to fix the workpiece to be sprayed on a special bracket, which is firmly mounted on a workbench; when the spraying device is started, the drive mechanism on the workbench or bracket drives the bracket and the workpiece to rotate together, thereby achieving uniform spraying on the surface of the workpiece; in some high-end manufacturing or precision machining fields, different workpieces often require differentiated coating treatments due to differences in material, shape, purpose, etc.;

[0004] In this case, if we continue to use traditional spraying technology, that is, all brackets rotate at the same speed, we will face some serious problems; first, for those workpieces that require thicker coatings, due to the fixed rotation speed, the spraying device can only spray limited coating materials per unit time, which may cause the coating to be too thin and unable to meet the special requirements of the workpiece; on the contrary, for those workpieces with complex structures or requiring fine spraying, due to the excessively fast rotation speed, the spraying material may not be able to fully penetrate into every detail of the workpiece, resulting in uneven coating or dead corners, so uneven coating may occur, so it needs to be improved.

During the coating process, the motor 14 can be driven to rotate the transmission wheel 2 15, because the transmission wheel 2 15 is connected to the surface of the transmission wheel 1 13 by the transmission belt 16, and then when the transmission wheel 2 15 rotates, the transmission wheel 2 15 will drive the transmission belt 16 to drive the transmission wheel 13 to rotate, and then the transmission wheel 13 will drive the connecting rod 12 to rotate. Rotate, and then the connecting rod 12 will drive the connecting shell 11 to rotate, and then the connecting shell 11 will drive the gear ring 1 6, the gear ring 2 7 and the connecting ring 8 to rotate, because the gear ring 1 6 and the gear ring 2 7 are all engaged with the gear 1 9 and the gear 2 10, and then the gear ring 1 6 and the gear ring 2 7 will drive the gear 1 9 and the gear 2 10 to rotate, and since the sizes of the gear 1 9 and the gear 2 10 are different, and then the multiple placement racks 5 will drive different workpieces to rotate at different differential speeds, and then different workpieces can be differentially coated, so that the workpieces can be evenly coated.

[0027] like Figure 3 As shown, a fixing groove 17 is provided at the top of the workbench 3 , and a supporting ring 18 located inside the fixing groove 17 is fixedly installed on the surface of the rotating rod 4 , and the supporting ring 18 is designed to be circular.

[0028] The above solution is adopted: through the design of the fixing groove 17 and the support ring 18, when the rotating rod 4 rotates, the rotating rod 4 will drive the support ring 18 to rotate inside the fixing groove 17, and then the support ring 18 can support and limit the rotating rod 4 to prevent it from falling off when the rotating rod 4 rotates.

[0031] like Figure 1 and Figure 2 As shown, a door panel 22 is provided at the front end of the base 1, and the fixed shell 2 and the door panel 22 are hinged by a hinge chain 23; the number of the placement racks 5 is eight, and each group of four placement racks 5 is located inside the top of the workbench 3.

[0032] The above scheme is adopted: through the design of the door panel 22 and the hinge chain 23, since the fixed shell 2 and the door panel 22 are hinged by the hinge chain 23, the door panel 22 can be rotated, and then it is convenient for the operator to install or disassemble the placement rack 5; through the design of the placement rack 5, since the placement rack 5 is a group of four, and gear one 9 is fixedly mounted on the surfaces of the four placement racks 5, and gear two 10 is fixedly connected to the bottom ends of the other four placement racks 5, the device can coat multiple workpieces at one time, thereby improving the efficiency of coating.

[0033] like Figure 1 As shown, the workbench 3 is circular in design, and the bottom end of the workbench 3 extends to the outside of the fixed shell 2, and the door panel 22 at the front end of the fixed shell 2 is semicircular in design.

Since the front end of the door panel 22 is semicircular in design, the inner wall of the door panel 22 can contact the surface of the workbench 3, thereby enabling the fixed shell 2 to be sealed.

[0035] The working principle and use process of this utility model:

[0036] First, the operator fixes different workpieces on the surface of the matching placement rack 5, and then the bottom end of the placement rack 5 can be inserted into the inside of the rotating rod 4, and then the magnet 19 and the magnet 2 20 will contact each other, and the placement rack 5 can be fixed by the principle of opposite attraction between the magnet 19 and the magnet 2 20. After the fixing is completed, the door panel 22 can be rotated to make the fixed shell 2 sealed;

[0037] Then the motor 14 can be driven to rotate the transmission wheel 2 15, and then the transmission wheel 2 15 will drive the transmission belt 16 and the transmission wheel 1 13 to rotate, and then the transmission wheel 1 13 will drive the connecting rod 12 and the connecting shell 11 to rotate, and then the connecting shell 11 will drive the gear ring 1 6 and the gear ring 2 7 to rotate, and then the gear ring 1 6 and the gear ring 2 7 will drive the gear 1 9 and the gear 2 10 to rotate, and then the gear 1 9 and the gear 2 10 will simultaneously drive the placement rack 5 to rotate. Since the sizes of the gear 1 9 and the gear 2 10 are different, multiple placement racks 5 can drive different workpieces to rotate at different differential speeds, and then different workpieces can be differentially coated, and then the workpieces can be evenly coated, and finally the operation process is completed.
