Description

Technical Field

[0001] The utility model belongs to the technical field of thermal spraying process fixtures, and particularly relates to a multi-station thermal spraying fixture. Background Art

[0002] The thermal spraying process is a technology that uses a certain heat source to heat powder-shaped or wire-shaped metal or non-metal materials to a molten or semi-molten state, and then sprays them onto the surface of a pre-treated substrate at a certain speed by means of the flame flow itself or compressed air to deposit and form a surface coating with various functions. The thermal spraying process is widely used in mechanical manufacturing enterprises. In the large-scale production process of enterprises, when spraying a large number of workpieces, the general method is to arrange the workpieces in a matrix and then spray them. The disadvantage of this method is that if there is a shortage or omission when arranging the workpieces, it will cause the workpieces to be missed sprayed.

[0003] For example, the patent document with the publication number "CN207276690U" discloses a thermal spraying device for annular workpieces, including a multi-station turntable, a spraying manipulator, and a spray gun for thermal spraying. The spray gun is installed on the spraying manipulator, and the spraying manipulator can move along the center line of the workpiece installed on the multi-station turntable, and its moving speed can be variable. Adopting the technical solution of this patent, the speed of the spray gun can be changed in real time during the moving process. When the spray gun moves to the inner hole area of the annular workpiece, the moving speed of the spray gun is greatly increased, reducing the residence time of the spray gun in the inner hole area of the annular workpiece, which can reduce the waste of materials and time. However, the spray gun can generally only spray along a single direction relative to the workpiece, resulting in ineffective coating coverage in some local areas of the workpiece surface, affecting the spraying quality of the workpiece. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides a multi-station thermal spraying fixture.

[0005] The utility model is achieved through the following technical solutions.

[0006] The utility model provides a multi-station thermal spraying fixture, including a motor, a base, and multiple support shafts. The support shafts are installed on the base using rolling bearings. The upper end of the support shaft is fixedly connected to a three-jaw chuck, and the lower end of the support shaft is fixedly connected to a driven wheel. The output shaft of the motor is fixedly connected to a driving wheel, and the driving wheel is meshed with one of the driven wheels through a first belt, and adjacent driven wheels are meshed with each other through a second belt.

[0007] The driving wheel and the driven wheels are all synchronous belt wheels, and the first belt and the second belt are both synchronous belts.

[0008] The number of the support shafts is multiple, and the multiple support shafts are arranged in a row at equal intervals along the length direction of the base.

[0009] The number of the supporting shafts is more than 5.

[0010] The multi-station thermal spraying fixture further includes an air-cooling pipe, the air-cooling pipe is fixedly connected with a plurality of air distribution pipes, one end of the base is also fixedly connected with a supporting shaft, the other end of the supporting shaft is fixedly connected with a supporting hoop, one side of the supporting hoop is hinged to one side of the cover hoop, when the other side of the supporting hoop is fixedly connected with the other side of the cover hoop, the air-cooling pipe is clamped between the supporting hoop and the cover hoop, and the end of the air distribution pipe is aligned with the radial direction of the three-jaw chuck.

[0011] The supporting hoop and the cover hoop are completely identical in shape and size.

[0012] Both the supporting hoop and the cover hoop are semi-circular.

[0013] The supporting shaft can be replaced by a steel pipe.

[0014] The multi-station thermal spraying fixture further includes a frame, and the base and the motor are both fixedly connected with the frame.

[0015] The beneficial effects of the present utility model are as follows: adopting the technical solution of the present utility model, the three-jaw chuck can be used to clamp workpieces of various shapes, so that the workpieces maintain a stable positioning position during the thermal spraying process. During the thermal spraying process of multiple workpieces, the power output by the motor is transmitted to the three-jaw chuck through the driving wheel, the driven wheel, and the supporting shaft, so that the workpieces rotate around the central axis of the three-jaw chuck, thereby enabling the coating sprayed by the spray gun to fully cover the surface of the workpieces, avoiding omission in local areas of the workpiece surface, improving the production efficiency, and ensuring the spraying quality.

[0022] Adopting the technical solution of the utility model, the three-jaw chuck can be used to clamp workpieces of various shapes, so that the workpieces can maintain a stable positioning position during the thermal spraying process. During the thermal spraying process of multiple workpieces, the power output by the motor is transmitted to the three-jaw chuck through the driving wheel, the driven wheel and the support shaft, so that the workpiece rotates around the central axis of the three-jaw chuck, so that the coating sprayed by the spray gun can fully cover the surface of the workpiece, avoiding omission in local areas of the workpiece surface, improving the production efficiency and ensuring the spraying quality.

[0023] Specifically, the driving wheel 6 and the driven wheels 5 are all synchronous belt wheels, and the first belt 7 and the second belt 8 are both synchronous belts.

One end of the base 2 is also fixedly connected to a support shaft 11, and the other end of the support shaft 11 is fixedly connected to a support hoop 12. One side of the support hoop 12 is hinged to one side of a cover hoop 13. When the other side of the support hoop 12 is fixedly connected to the other side of the cover hoop 13, the air-cooling pipe 9 is clamped between the support hoop 12 and the cover hoop 13, and the end of the air distribution pipe 10 is aligned with the radial direction of the three-jaw chuck 4. Preferably, the shapes and sizes of the support hoop 12 and the cover hoop 13 are exactly the same. The support hoop 12 and the cover hoop 13 are both semi-circular.
