Description

Technical Field

[0001] The utility model relates to the technical field of turbocharger production, in particular to a painting tool for a turbocharger housing. Background Art

[0002] As an air compressor, turbocharger is a common device in automobile engines. It uses the exhaust gas generated by the engine to drive the turbine. When the engine speed increases, the exhaust gas discharge speed and the turbine speed also increase synchronously. The impeller compresses more air into the cylinder. The increased air pressure and density can burn more fuel. Increasing the fuel amount and adjusting the engine speed accordingly can increase the engine's output power.

[0003] When painting the turbocharger housing, a position adjustment mechanism is usually required to assist in the spraying. When adjusting the position, the housing needs to be positioned. When spraying the positioned housing, some positions are easily obstructed, affecting the normal spraying of the housing. Utility Model Content

[0004] The purpose of the utility model is to provide a painting tool for a turbocharger housing in view of the defects of the prior art, so as to solve the problems raised in the above background technology.

[0005] A painting tool for a turbocharger housing comprises a support, a spray pipe installed on the support and a position adjustment mechanism installed on the support, the position adjustment mechanism comprises a first limit shaft, a second limit shaft, a first gear, a second gear, a toothed plate, a cylinder and a motor, the first limit shaft and the second limit shaft rotate on both sides of the support respectively, and a limit end for limiting the housing is installed at one end close to the first limit shaft and the second limit shaft, the first gear rotates on the support and is slidably connected to the second limit shaft, the second gear is fixedly installed at the output end of the motor, the toothed plate slides up and down along the limit plate fixed on the support, and is meshed and connected with the first gear and the second gear, the cylinder is installed on the support, and its output end is movably connected to the second limit shaft through a connecting plate.

[0006] By adopting the above technical solution, the influence of positioning the shell body and the fact that some positions are not sprayed with paint can be reduced.

[0007] One side edge of the second limiting shaft is protruding outwards and is rotated on the support through an adapted ring.

[0008] By adopting the above technical solution, the first gear can drive the second limiting shaft to rotate normally, and the first gear can be slidably connected to the second limiting shaft.

[0009] The limiting end is arranged in a truncated cone-shaped structure.

[0010] By adopting the above technical solution, the shell is positioned.

[0011] The center point of the first limiting axis, the center point of the second limiting axis and the center point of the limiting end are all on the same horizontal line.

[0012] By adopting the above technical solution, it is convenient to position the shell.

[0013] The upper end of the connecting plate is rotatably connected to the second limiting shaft, and the lower end is fixedly connected to the output end of the cylinder.

[0014] By adopting the above technical solution, the driving motor drives the second gear to rotate, and the second gear drives the tooth plate to move up and down along the limit plate, while driving the first gear to rotate. When the first gear rotates, it can drive the second limit shaft to rotate on the support. Since the connecting plate and the second limit shaft are rotatably connected, the connecting plate will not affect the normal rotation of the second limit shaft.

[0015] The beneficial effects of the paint spraying tooling for the turbocharger housing of the utility model are:

[0016] The driving cylinder pushes the second limit shaft to push the limit end through the connecting plate, so that the middle hole of the shell can be positioned by the two limit ends; the driving motor drives the second gear to rotate, and the second gear drives the tooth plate to move up and down along the limit plate, and drives the first gear to rotate at the same time. When the first gear rotates, it can drive the second limit shaft to rotate on the support. Because the connecting plate and the second limit shaft are rotatably connected, the connecting plate will not affect the normal rotation of the second limit shaft; at this time, the second limit shaft drives the shell to rotate through the limit end, turns on the external paint pump, and transports the paint liquid to the spray pipe, and sprays the shell through the spray pipe. After the shell is positioned, the obstruction of the position adjustment mechanism can be effectively reduced, which affects the full body spraying of the shell. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0021] Reference Figure 1-2 , a painting tool for a turbocharger housing, comprising a support 1, a spray pipe 2 installed on the support 1 and a position adjustment mechanism installed on the support 1, the position adjustment mechanism comprising a first limiting shaft 3, a second limiting shaft 4, a first gear 6, a second gear 7, a toothed plate 8, a cylinder 10 and a motor 11, the first limiting shaft 3 and the second limiting shaft 4 rotate on both sides of the support 1 respectively, and a limiting end 5 for limiting the housing 13 is installed at one end close to the first limiting shaft 3 and the second limiting shaft 4, the first gear 6 rotates on the support 1 and is slidably connected with the second limiting shaft 4, the second gear 7 is fixedly installed at the output end of the motor 11, the toothed plate 8 slides up and down along the limiting plate 9 fixed on the support 1, and is meshed and connected with the first gear 6 and the second gear 7, the cylinder 10 is installed on the support 1, and its output end is movably connected with the second limiting shaft 4 through a connecting plate 12;

[0022] The housing 13 can be placed between the two limiting ends 5 at the ends of the first limiting shaft 3 and the second limiting shaft 4, and the driving cylinder 10 pushes the second limiting shaft 4 to push the limiting end 5 through the connecting plate 12, so that the middle hole of the housing 13 can be positioned through the two limiting ends 5;

[0023] The upper end of the connecting plate 12 is rotatably connected to the second limiting shaft 4, and the lower end is fixedly connected to the output end of the cylinder 10. The driving motor 11 drives the second gear 7 to rotate, and the second gear 7 drives the toothed plate 8 to move up and down along the limiting plate 9, and drives the first gear 6 to rotate at the same time. When the first gear 6 rotates, it can drive the second limiting shaft 4 to rotate on the support 1. Because the connecting plate 12 and the second limiting shaft 4 are rotatably connected, the connecting plate 12 will not affect the normal rotation of the second limiting shaft 4.

[0024] At this time, the second limiting shaft 4 drives the housing 13 to rotate through the limiting end 5, and the external paint pump is turned on to transport the paint liquid to the spray pipe 2, and the housing 13 is sprayed with paint through the spray pipe 2.

[0025] The spraying tubes 2 on both sides of the upper end of the support 1 are both arranged toward the shell 13, so as to spray the entire shell 13. The spraying tubes 2 can also be adjusted in height and angle according to the needs of actual applications to adapt to the shell 13 and spray the entire shell 13.

[0026] The first limiting shaft 3 rotates on the support 1, and the second limiting shaft 4 can rotate and slide on the support 1, so as to adjust the distance between the second limiting shaft 4 and the first limiting shaft 3, and limit the housing 13;

[0027] One side of the second limiting shaft 4 is protruding outwards and is rotated on the support 1 through an adapted ring.

[0028] The limiting end 5 is a truncated cone-shaped structure. The structure of the limiting end 5 can adapt to the size of the middle hole of the shell 13 to limit the shell 13.

[0029] The center point of the first limiting axis 3, the center point of the second limiting axis 4 and the center point of the limiting end 5 are all on the same horizontal line; the second limiting axis 4 and the first limiting axis 3 are arranged on the same horizontal line. When the shell 13 is limited by the limiting end 5, the position of the shell 13 can be placed regularly to facilitate spraying of the shell 13 through the spray pipe 2.

[0030] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
