Description

Technical Field

[0001] This invention belongs to the field of machining technology, and in particular relates to a double-sided automatic sandblasting device for carbide cutting tools. Background Technology

[0002] Carbide inserts are inserts made of cemented carbide, an alloy material produced by powder metallurgy from a hard compound of refractory metals and a binder metal. Carbide possesses a range of excellent properties, including high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance. During machining, to improve surface cleanliness and enhance the mechanical properties of carbide inserts, both sides are sandblasted.

[0003] An existing automatic double-sided sandblasting device for carbide blades includes a device box. Inside the device box, there are sequentially arranged a lifting mechanism for lifting two sets of worktables, a moving mechanism for moving one set of worktables horizontally, a control mechanism for moving the sandblasting machine horizontally, and a flipping mechanism for rotating one set of worktables. Magnetic suction components for adsorbing carbide blades are fixed on the two sets of worktables.

[0004] In existing double-sided automatic sandblasting devices for carbide inserts, the magnetic component is an electromagnet. The electromagnet attracts the carbide insert by energizing it. During sandblasting, the sandblasting machine impacts the surface of the carbide insert, leaving some metal debris. When the electromagnet attracts the carbide insert, it also attracts this metal debris, resulting in a layer of metal debris between the electromagnet and the carbide insert. This weakens the electromagnet's attraction to the carbide insert and makes it impossible to guarantee the stability of the carbide insert during rotation.

[0005] Therefore, in view of the above situation, there is an urgent need to develop a double-sided automatic sandblasting device for carbide blades to overcome the shortcomings in current practical applications. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a double-sided automatic sandblasting device for carbide blades to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A double-sided automatic sandblasting device for carbide blades includes a base. One end of the base is equipped with a tilting mechanism for rotating the mounting base. Tilting seats are mounted on both the upper and lower ends of the mounting base via connecting columns. Two sets of conveyor belts are mounted on the other end of the base. One set of conveyor belts is located above the top-mounted tilting seats, and the other set is located below the bottom-mounted tilting seats. A mounting bracket for mounting a sandblasting machine is fixed on the base above the two sets of conveyor belts. The device also includes:

[0009] A fixing mechanism, comprising a drive component, a control component, and a fixing component, wherein one end of the drive component is fixed to one side of the flipping mechanism, and the other end of the drive component is connected to a control component distributed on two sets of flipping seats, and one end of the control component passes through the flipping seat and is connected to the fixing component.

[0010] The control assembly includes a first connector, a control component, a second gear, a second rack, a connecting seat, and a guide roller. One end of the first connector is connected to the drive assembly, and the other end of the first connector is movably connected to the control component distributed on the tilting seat. A second gear that meshes with the second rack is fixed on one end of the control component, and the other end of the control component passes through the tilting seat and is connected to the fixing assembly. One end of the second rack is movably mounted on the second gear, and the other end of the second rack is rotatably connected to the connecting seat. The connecting seat is slidably fitted onto the guide roller, and the guide roller is tilted and fixed on the tilting seat.

[0011] The flipping mechanism drives the mounting base to rotate, and the mounting base drives the upper and lower sets of flipping seats to rotate. The upper and lower sets of flipping seats achieve automatic flipping of the blade through rotation and cooperation with the fixing mechanism.

[0012] The upper conveyor belt transports the blades that have undergone single-sided sandblasting to the upper tilting seat. The drive component drives the upper and lower sets of first connecting parts to move in the same direction. The first connecting parts drive the fixed components on the upper and lower sets of tilting seats to move in the same direction through the control component. The control component drives the second gear to move. The second gear drives the connecting seat to slide on the guide roller through the second rack. The connecting seat drives the second rack to move laterally by cooperating with the guide roller. The second rack drives the second gear to rotate by moving laterally. The second gear drives the control component to rotate. The control component drives the fixed components to rotate.

[0013] The fixing components on the upper tilting seat fix the blade by rotating and moving, while the fixing components on the lower tilting seat release the blade by rotating and moving. The blade falls freely onto the lower conveyor belt, which then transports it to the bottom of the sandblasting machine, thus achieving automatic sandblasting of both sides of the blade.

[0014] As a further technical solution of the present invention, the driving component includes a first driving member, a transmission module, a rotating shaft, a first gear and a first rack. The first driving member is fixed on one side of the flipping mechanism. The first driving member is connected to the rotating shaft through the transmission module. The rotating shaft is movably installed in the mounting base. A first gear that meshes with the first rack is fixed on the rotating shaft. The first rack is slidably installed on the mounting base. The two ends of the first rack are respectively fixedly connected to two sets of first connecting members.

[0015] As a further technical solution of the present invention, the fixing component includes a fixing seat, a telescopic member, an elastic member and a fixing member. The fixing seat is fixed on the control member. The telescopic member is distributed on one side of the fixing seat. The fixing member is fixed to one end of the telescopic member. The elastic member is fitted on the telescopic member between the fixing member and the fixing seat.

[0016] As a further technical solution of the present invention, the flipping mechanism includes a second driving member, a third gear, a fourth gear, a rotating member, a second connecting member, and a flipping shaft. The flipping shaft is distributed at both ends of the mounting base. A second connecting member is fixed to one end of the flipping shaft. The second connecting member is movably mounted on both sides of the device base through the rotating member. The second driving member is mounted on one side of the device base. A third gear is fixed to the output end of the second driving member. The third gear meshes with a fourth gear fixed on a set of rotating members.

[0017] As a further technical solution of the present invention, the circles formed by the rotation trajectory of the flipping shaft are all concentric with the fourth gear and the rotating component.

[0018] As a further technical solution of the present invention, a conveyor for conveying the blade is also installed on one side of the conveyor belt located above the flipping seat on the device base. The conveyor is a frustum-shaped cylindrical structure.

[0019] As a further technical solution of the present invention, a limiting frame is also provided on the fixed components distributed around the flipping seat, and the limiting frame is used to block the blade conveyed by the conveyor.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] The flipping mechanism drives the mounting base to rotate, which in turn drives the upper and lower sets of flipping seats to rotate. The upper and lower sets of flipping seats achieve automatic flipping of the blade by rotating and cooperating with the fixing mechanism.

[0022] The conveyor belt at the top transports the blades that have completed single-sided sandblasting to the upper tilting seat. The first drive unit drives the rotating shaft to rotate through the transmission module. The rotating shaft drives the first gear to rotate. The first gear drives the first rack to move by rotating. The first rack drives the upper and lower sets of first connecting parts to move in the same direction. The first connecting parts drive the fixed seats on the upper and lower sets of tilting seats to move in the same direction through the control unit. The fixed seats drive the fixed parts to move through the telescopic and elastic parts.

[0023] The control component drives the second gear to move, and the second gear drives the connecting seat to slide on the guide roller through the second rack. The connecting seat drives the second rack to move laterally by cooperating with the guide roller. The second rack drives the second gear to rotate by moving laterally. The second gear drives the control component to rotate, and the control component drives the fixing component to rotate. The upper and lower fixed components rotate towards the direction closer to and away from the blade, respectively.

[0024] The upper fixing component secures the blade by rotating and moving, and the fixing component uses a multi-point fixing method to fix the blade, which improves the fixing quality of the blade and the stability of the blade when flipping. The lower fixing component enables the rapid release of the blade by rotating and moving. The blade falls freely onto the lower conveyor belt, which then transports it to the bottom of the sandblasting machine, thereby realizing automatic sandblasting of both sides of the blade.
