Description

Technical Field

[0001] This utility model relates to the field of sandblasting machine technology, specifically a rotary table type automatic sandblasting machine. Background Technology

[0002] Sandblasting machines use compressed air to propel abrasive materials (steel grit, quartz sand, corundum, glass sand, resin sand) at high speed onto the surface of the workpiece. This alters the mechanical properties of the workpiece's surface. Due to the impact and cutting action of the abrasive material, the workpiece surface achieves a certain level of cleanliness and varying roughness, thus improving its mechanical properties. This enhances the workpiece's fatigue resistance, increases adhesion between the workpiece surface and coatings, extends coating durability, and facilitates paint leveling and decoration. Sandblasting removes impurities, discoloration, and oxide layers from the workpiece surface, while simultaneously roughening the surface, eliminating residual stress, and increasing surface hardness. In gear manufacturing, sandblasting is used to sandblast the gear teeth to optimize their performance, such as increasing hardness, wear resistance, and oil film adhesion.

[0003] In existing technology, the gear to be sandblasted is usually fixed to the upper end of a turntable by a clamp. The turntable drives the gear to rotate, and the abrasive inside the sandblasting machine is sprayed onto the tooth surface of the gear through a spray gun to complete the sandblasting.

[0004] However, using clamps to fix gears is not very convenient; furthermore, only after one gear has been sandblasted and removed can another gear to be sandblasted be clamped and fixed before sandblasting can begin. This method results in low work efficiency when there are too many gears to be sandblasted. Therefore, it is necessary to propose a rotary table automatic sandblasting machine to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a rotary table type automatic sandblasting machine, which is convenient to operate when fixing gears and can improve work efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rotary table type automatic sandblasting machine, including a horizontal plate, a sand cylinder is arranged above the horizontal plate, a discharge valve pipe is connected to the lower end of the sand cylinder, a horizontal pipe is connected to the lower end of the discharge valve pipe, a spray gun is installed at the left end of the horizontal pipe, a steering column is rotatably connected to the upper end of the horizontal plate, a disc is fixedly connected to the upper end of the steering column, two left and right distributed turntables are rotatably connected to the upper end of the disc, the two turntables are respectively driven by two first motors installed at the lower end of the disc, a limit plate is fixedly connected to the upper end of each of the two turntables, and a positioning column is fixedly connected to the upper end of each of the two limit plates;

[0008] Two elastic pads are fixedly connected to the outer walls of the two positioning posts, and an arc-shaped plate is fixedly connected to the outer walls of the four elastic pads.

[0009] In order to drive the steering column to rotate 180 degrees in either the forward or reverse direction, as a preferred embodiment of the rotary table automatic sandblasting machine of this utility model, the driving mechanism includes a driving frame fixedly connected to the lower end of the horizontal plate, a worm gear rotatably connected inside the driving frame, the worm gear being driven by a second motor installed at the right end of the driving frame, a worm wheel meshing with the outer wall of the worm gear, and the shaft of the worm wheel passing through the horizontal plate and fixedly connected to the steering column.

[0010] In order to guide the gears to the outer walls of the two arc-shaped plates on the same side and improve the convenience of operation, as a preferred embodiment of the rotary table automatic sandblasting machine of this utility model, the upper ends of the four arc-shaped plates are all fixedly connected to guide plates.

[0011] To prevent abrasive from being sprayed onto workers, a baffle is preferably fixedly connected to the upper end of the rotary table automatic sandblasting machine of this utility model.

[0012] To prevent abrasive accumulation inside the sand cylinder, in a preferred embodiment of the rotary table automatic sandblasting machine of this utility model, a stirring frame is rotatably connected to the top of the sand cylinder, and the stirring frame is driven by a third motor installed at the top of the sand cylinder.

[0013] To prevent abrasive from entering the horizontal pipe located to the right of the one-way valve and to facilitate connection to the pipeline of the external compressed gas supply device, a one-way valve is preferably provided inside the horizontal pipe in the rotary table automatic sandblasting machine of this utility model.

[0014] A connector is installed at the right end of the horizontal pipe.

[0015] To facilitate the installation and fixation of the sand cylinder, in a preferred embodiment of the rotary table automatic sandblasting machine of this utility model, two perforated plates distributed on the left and right are fixedly connected between the sand cylinder and the horizontal plate, and the horizontal pipe and the spray gun are located inside the two perforated plates.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] The two gears are respectively fitted onto the outer walls of the two arc-shaped plates on the same side, and the two gears are respectively in contact with the upper ends of the two limiting plates. At this time, the rebound force of the elastic pad can make the inner walls of the two gears tightly abut against the outer walls of the two arc-shaped plates on the same side, thereby achieving the purpose of convenient operation when fixing the gears.

[0018] By rotating the gear in the right area at a constant speed, the abrasive is sprayed onto the tooth surface of the gear as the spray gun is directly facing it. Then, the other gear to be sandblasted rotates to the right area, while the gear that has been sandblasted rotates to the left area.

After the gear in the right area is sandblasted and the gear in the left area is fixed, the disc is rotated 180 degrees in the opposite direction, and the same steps are repeated to improve work efficiency.

[0024] A drive mechanism is provided on the lower side of the steering column 7;

[0025] Two elastic pads 12 are fixedly connected to the outer walls of the two positioning posts 11, and arc-shaped plates 13 are fixedly connected to the outer walls of the four elastic pads 12.

[0026] In this embodiment: When in use, since the elastic pad 12 has elasticity, the two gears to be sandblasted can be respectively fitted into the outer walls of the two arc-shaped plates 13 on the same side, and the two gears can be made to contact the upper ends of the two limiting plates 10 respectively. At this time, the rebound force of the elastic pad 12 can make the inner walls of the two gears tightly abut against the outer walls of the two arc-shaped plates 13 on the same side, thus completing the fixation of the two gears. In this way, the purpose of convenient operation is achieved when fixing the gears.

[0027] An external gas supply device delivers compressed air into the horizontal pipe 4 and opens the valve of the discharge valve pipe 3. The abrasive inside the sand cylinder 2 enters the horizontal pipe 4 and, along with the gas flow, enters the spray gun 5. Simultaneously, the first motor 22 in the right area drives the right-side turntable 9, the right-side limiting plate 10, and the right-side fixed gear to rotate at a constant speed. Since the spray gun 5 is directly facing the tooth surface of the gear in the right area, the abrasive is sprayed onto the tooth surface of the right-side gear through the spray gun 5. After the tooth surface of the right-side gear is sandblasted, the drive mechanism drives the steering column 7 to rotate 180 degrees, thereby driving the disc 8, the two turntables 9, and the two... The limiting plate 10 and two gears rotate 180 degrees, so that the other gear to be sandblasted rotates to the right area, while the gear that has been sandblasted rotates to the left area. At this time, the gear in the right area is sandblasted according to the same steps as above. At the same time as sandblasting, the gear in the left area can be removed, and the other gear to be sandblasted is fixed to the outside of the two arc plates 13 in the left area. After the gear in the right area is sandblasted and the gear in the left area is fixed, the disc 8 is rotated 180 degrees in the opposite direction, and then the operation is continued according to the same steps as above, thereby improving work efficiency.

[0028] As a technical optimization of this utility model, the drive mechanism includes a drive frame 15 fixedly connected to the lower end of the horizontal plate 1. A worm gear 16 is rotatably connected inside the drive frame 15. The worm gear 16 is driven by a second motor 18 installed on the right end of the drive frame 15. A worm wheel 17 is meshed with the outer wall of the worm gear 16. The shaft of the worm wheel 17 passes through the horizontal plate 1 and is fixedly connected to the steering column 7.

[0029] In this embodiment: the second motor 18 drives the worm gear 16 to rotate, which in turn drives the worm wheel 17 to rotate, thereby driving the steering column 7 to rotate 180 degrees in the forward or reverse direction.

[0030] As a technical optimization of this utility model, guide plates 14 are fixedly connected to the upper ends of the four arc-shaped plates 13.

[0031] In this embodiment, since the outer sides of the four guide plates 14 are inclined, it is easier to guide the gear to the outer wall of the two arc-shaped plates 13 on the same side, thus improving the ease of operation.

[0032] As a technical optimization of this utility model, a baffle 21 is fixedly connected to the upper end of the disc 8.

[0033] In this embodiment, a baffle 21 is provided to prevent abrasive from being sprayed onto the workers.

[0034] As a technical optimization of this utility model, a stirring frame 19 is rotatably connected to the top of the inside of the sand cylinder 2, and the stirring frame 19 is driven by a third motor 20 installed on the upper end of the sand cylinder 2.

[0035] In this embodiment, the stirring rack 19 is driven to rotate by the third motor 20, thereby constantly stirring the abrasive inside the sand cylinder 2 to prevent it from accumulating.

[0036] As a technical optimization of this utility model, a one-way valve is provided inside the horizontal pipe 4;

[0037] A connector is installed at the right end of horizontal pipe 4.

[0038] In this embodiment: a one-way valve is provided to prevent abrasive from entering the horizontal pipe 4 located to the right of the one-way valve, and a connector is provided to facilitate connection to the pipeline of the external compressed gas supply device.

[0039] As a technical optimization of this utility model, two perforated plates 6 are fixedly connected between the sand cylinder 2 and the horizontal plate 1, and the horizontal pipe 4 and the spray gun 5 are located inside the two perforated plates 6.

[0040] In this embodiment, two perforated plates 6 are provided to facilitate the installation and fixing of the sand cylinder 2.

[0041] Working principle: During use, due to the elasticity of the elastic pad 12, the two gears to be sandblasted can be respectively fitted into the outer walls of the two arc-shaped plates 13 on the same side, and the two gears can be made to contact the upper ends of the two limiting plates 10 respectively. At this time, the rebound force of the elastic pad 12 can make the inner walls of the two gears tightly abut against the outer walls of the two arc-shaped plates 13 on the same side, thus completing the fixation of the two gears. In this way, the operation of fixing the gears is convenient.

[0042] An external gas supply device delivers compressed air into the horizontal pipe 4 and opens the valve of the discharge valve pipe 3. The abrasive inside the sand cylinder 2 enters the horizontal pipe 4 and, along with the gas flow, enters the spray gun 5. Simultaneously, the first motor 22 in the right area drives the right-side turntable 9, the right-side limiting plate 10, and the right-side fixed gear to rotate at a constant speed. Since the spray gun 5 is directly facing the tooth surface of the gear in the right area, the abrasive is sprayed onto the tooth surface of the right-side gear through the spray gun 5. After the tooth surface of the right-side gear is sandblasted, the second motor 18 drives the worm gear 16 to rotate, which in turn drives the worm wheel 17 to rotate, thereby driving the steering column 7 to rotate 180 degrees, thus... The rotating disc 8, two turntables 9, two limiting plates 10, and two gears rotate 180 degrees, causing the other gear to be sandblasted to rotate to the right side, while the gear that has been sandblasted rotates to the left side. At this time, the gear in the right side is sandblasted according to the same steps as above. While sandblasting, the gear in the left side can be removed, and the other gear to be sandblasted is fixed to the outside of the two arc plates 13 in the left side. After the gear in the right side is sandblasted and the gear in the left side is fixed, the disc 8 is rotated 180 degrees in the opposite direction, and the operation is continued according to the same steps as above, thereby improving work efficiency.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
