[0002] With the development of the times, all walks of life pay more and more attention to the quality, life and reliability of workpieces. In order to improve the mechanical properties and insulation properties of each workpiece and extend its service life under complex working conditions, the use of surface coating technology can effectively improve the service life of the workpiece, while ensuring the reliability of the equipment, greatly reducing maintenance costs and improving safety. Some existing coating equipment lacks special fixtures in the process of coating the bearing surface, and the operator needs to raise the bearing and fix it by himself, resulting in a long time to install a workpiece. At the same time, some bearings only need to be coated on their surface. In the absence of special fixtures, the coating ions are easy to run to the inner ring of the bearing, resulting in coating color difference on the inner ring. Utility Model Content

[0003] In view of the problem that the existing coating equipment takes a long time to install bearings in the absence of special fixtures, and the coating ions easily run to the inner ring of the bearing, resulting in coating color difference on the inner ring, the present application proposes a coating tooling fixture to solve the above problems.

[0004] The present application proposes a coating fixture, comprising a fixed shaft, a workpiece to be plated, a first fastener and a second fastener, the first fastener and the second fastener having the same structure and being arranged opposite to each other, the fixed shaft vertically upwardly passes through the second fastener, the workpiece to be plated and the first fastener in sequence; the first fastener and the second fastener cooperate with the inner ring of the workpiece to be plated, and respectively fit with the upper surface and the lower surface of the workpiece to be plated; the fixed shaft also passes through a support member, the support member is arranged below the second fastener, the first fastener can press the workpiece to be plated downward, the fixed shaft can drive the first fastener and the second fastener to rotate, and the first fastener and the second fastener arranged opposite to each other cooperate with the workpiece to be plated to prevent the upper and lower surfaces of the workpiece to be plated from being exposed to the coating space, and the workpiece to be plated can be rotated around the fixed shaft with the first fastener and the second fastener for coating, and at the same time, the support member presses the lower surface of the second fastener to make the workpiece to be plated at a suitable height.

[0005] In some specific embodiments, the first fastener and the second fastener both include a cover plate and a positioning boss, and the outer circle size of the positioning boss is smaller than the outer circle size of the cover plate. With this structure, the first fastener and the second fastener can cooperate with the inner circle of the workpiece to be plated through the positioning boss, and fit with the upper and lower surfaces of the workpiece to be plated through the cover plate.

[0006] In some specific embodiments, the workpiece to be plated is a circular ring structure, the upper and lower surfaces of the workpiece to be plated can be fitted with the cover plate, and the inner ring size of the workpiece to be plated is equal to the outer ring size of the positioning boss. With this structure, the cover plate can completely cover the inner ring of the workpiece to be plated, preventing plating ions from entering the inner ring from the upper and lower surfaces of the workpiece to be plated during the plating process.

[0007] In some specific embodiments, the outer circle of the positioning boss can fit with the inner circle of the workpiece to be plated, and the height of the positioning boss is less than or equal to half of the height of the workpiece to be plated. This setting can prevent the positioning boss from being too high, resulting in the upper and lower surfaces of the workpiece to be plated not being able to fully fit with the cover plate.

[0008] In some specific embodiments, a positioning hole is opened in the center of the cover plate, and the positioning hole has a size that is adapted to the fixed shaft. The inner circle size of the positioning boss is larger than the size of the positioning hole. With this arrangement, the fixed shaft can pass through the center of the positioning boss and the workpiece to be plated, so that the fixed shaft can drive the first fastener, the workpiece to be plated and the second fastener to rotate around the axis.

[0009] In some specific embodiments, the cross-sectional shape of the fixed shaft and the shape of the positioning hole are both D-shaped. With this arrangement, the first fastener and the second fastener can rotate synchronously with the fixed shaft, and relative rotation between the fixed shaft and the first fastener and the second fastener can be prevented during rotation.

[0010] In some specific embodiments, the fixed shaft includes a fixed part and a connecting part, a support plate is arranged between the fixed part and the connecting part, and the fixed part, the connecting part and the support plate are fixed by welding. With this structure, the fixed part can be connected to the coating equipment through the connecting part, thereby driving the fixed part to rotate. At the same time, the welding fixing method ensures the stability of the connection among the fixed part, the connecting part and the support plate.

[0011] In some specific embodiments, the upper surface of the support plate can be against the lower surface of the support member, and the outer ring size of the support plate is larger than the outer ring size of the support member. With this setting, the support member can be limited to prevent the support member from falling, thereby providing strong support for the workpiece to be plated.

[0013] The utility model mainly solves the problem that the existing coating equipment needs to manually raise the bearing before coating, the installation of the bearing takes a long time, and it cannot prevent the coating ions from easily running to the inner ring of the bearing when only the surface of the bearing needs to be coated, resulting in the problem of coating color difference on the inner ring. The application proposes a coating fixture, including a fixed shaft and a first fastener and a second fastener with the same structure. The first fastener and the second fastener both include a cover plate and a positioning boss. A positioning hole is opened in the center of the cover plate to cooperate with the fixed shaft limit. The positioning boss cooperates with the inner ring of the part to be plated, and the upper and lower surfaces of the part to be plated are pressed by the cover plate, and then the positioning shaft is driven by the coating equipment to drive the part to be plated to rotate synchronously and perform coating. Before coating, only the first fastener needs to be removed to quickly install the part to be plated. At the same time, under the protection of the cover plate, the coating ions cannot enter the inner ring of the part to be plated from the upper and lower surfaces of the part to be plated, thereby avoiding the coating color difference of the part to be plated that only needs surface coating.

The specific principle and structure are combined Figure 2-6 Detailed description of the application.

[0025] Figure 2 A partial enlarged view of a coating fixture according to an embodiment of the utility model is shown. As shown in the figure, the fixed shaft 01 includes a fixing portion 09, a connecting portion 10 and a support plate 11. The fixing portion 09 passes through the support member 05. The support plate 11 is arranged between the fixing portion 09 and the connecting portion 10, and the upper surface of the support plate 11 can be against the lower surface of the support member 05.

[0026] In a specific embodiment, the inner ring of the support member 05 has a size that matches the fixing portion 09, and the outer ring size of the support member 05 is smaller than the outer ring size of the support plate 11, so that the upper surface of the support plate 11 completely covers the lower surface of the support member 05, preventing the support member 05 from sliding off the fixing portion 09 due to gravity.

[0027] In a specific embodiment, the fixing portion 09 , the connecting portion 10 and the supporting plate 11 are fixed by welding, so that the fixing shaft 01 has higher strength and rigidity and can better resist the torsional force.

[0028] Figure 3 A schematic diagram of a fastener structure according to a specific embodiment of the utility model is shown. As shown in the figure, the first fastener 03 and the second fastener 04 both include a cover plate 06 and a positioning boss 07 , and a positioning hole 08 is opened in the center of the cover plate 06 .

[0029] In a specific embodiment, the outer circle size of the cover plate 06 is larger than the outer circle size of the positioning boss 07 , and the inner circle size of the positioning boss 07 is larger than the size of the positioning hole 08 .

[0030] In a specific embodiment, the positioning hole 08 is a D-shaped hole, and the diameter of the arc portion of the positioning hole 08 is φ20 mm, and the distance between the midpoint of the straight line portion of the positioning hole 08 and the vertex of the arc portion is 18 mm.

[0032] Figure 4 FIG. 1 shows a schematic diagram of the cooperation between a piece to be plated and a fastener according to a specific embodiment of the utility model, as shown in FIG. Figure 3-4 As shown, the first fastener 03 and the second fastener 04 are respectively arranged above and below the workpiece to be plated 02, the outer circles of the positioning bosses 07 of the first fastener 03 and the second fastener 04 can be fitted with the inner circle of the workpiece to be plated 02, and the cover plates 06 of the first fastener 03 and the second fastener 04 can be fitted with the upper surface and the lower surface of the workpiece to be plated 02, respectively.

[0033] In a specific embodiment, the inner circle size of the workpiece 02 to be plated is equal to the outer circle size of the positioning boss, and the height of the positioning boss 07 is less than or equal to one half of the height of the workpiece 02 to be plated. This setting can make the inner circle of the workpiece 02 to be plated be completely covered by the cover plate 04, and can prevent the height of the positioning boss 07 from being too high, resulting in the cover plate 06 being unable to fully fit with the workpiece 02 to be plated.

Please refer to Figure 1-6 The fixed shaft 01 is placed in the coating space of the coating equipment 12 and cooperates with the coating equipment 12. The fixed shaft 01 passes through the support member 05, the second fastener 04, the workpiece 02 to be plated and the first fastener 03 from bottom to top in sequence. The lower surface of the support member 05 abuts against the upper surface of the support plate 11, and the upper surface of the support member 05 abuts against the lower surface of the second fastener 04, which plays a role in raising and preventing the second fastener 04 from falling. The lower surface of the workpiece 02 to be plated is in contact with the cover plate 06 of the second fastener 04, and the first fastener 03 can press the workpiece 02 to be plated downward under the action of gravity.

When the first fastener 03 and the second fastener 04 press the workpiece 02 to be plated, the workpiece 02 to be plated can rotate synchronously with the fixed shaft 01 and be plated, and under the protection of the cover plate 06, the coating ions are not easy to enter the inner circle from the upper and lower surfaces of the workpiece 02 to be plated.

[0038] The utility model mainly solves the problem that the existing coating equipment needs to manually raise the bearing before coating, the installation of the bearing takes a long time, and it cannot prevent the coating ions from easily running to the inner ring of the bearing when only the bearing surface needs to be coated, resulting in coating color difference on the inner ring. The present application proposes a coating fixture, comprising a fixed shaft 01 and a first fastener 03 and a second fastener 04 with the same structure.

The positioning boss 07 cooperates with the inner ring of the workpiece 02 to be plated, and the upper and lower surfaces of the workpiece 02 to be plated are pressed by the cover plate 06. Then, the positioning shaft 01 is driven by the coating equipment 12 to drive the workpiece 02 to rotate synchronously and perform coating. Before coating, only the first fastener 03 needs to be removed to quickly install the workpiece 02. At the same time, under the protection of the cover plate 06, the coating ions cannot enter the inner ring of the workpiece 02 from the upper and lower surfaces of the workpiece 02 to be plated, thereby avoiding the coating color difference of the workpiece 02 to be plated which only needs surface coating.
