Description

Technical Field

[0002] With the continuous improvement of the manufacturing level of modern heavy industry, the types and products of metal castings have gradually increased. Although a cooling process is required when the die-casting machine is used to form products, there is still residual heat that cannot be touched by human hands when the die is removed from the mold. Therefore, in the process of removing materials from the mold after die-casting, it is still necessary to rely on a robotic arm to grab and unload the materials. This places high demands on the gripping performance and gripping efficiency of the robotic arm. The existing robotic arm transports the hub by clamping the center axis of the hub. The clamping of the hub is unstable by only clamping one point. At the same time, the clamping point of the hub is subjected to greater force, and indentations are likely to appear at the force point, affecting the surface of the hub. Secondly, after the hub is removed from the mold, it has a certain temperature, and employees may easily get burned if they accidentally touch it during the clamping filtration. Summary of the invention

[0007] The heat dissipation device is located on the outer surface of the protection device, and the heat dissipation device includes a heat dissipation nozzle. The deflection of the heat dissipation nozzle dissipates heat for the clamped magnesium wheel hub.

[0008] Preferably, the driving mechanism also includes a driving motor, which is fixedly mounted on the inner wall of the connecting shell, and a driving rod is fixedly mounted on one end of the output shaft of the driving motor. The inner wall of the connecting shell is rotatably connected to a worm sleeve through a bearing seat, and the worm sleeve is rotatably sleeved on the outer surface of the driving rod. A double toothed disk is slidably inserted into the outer surface of the driving rod, and a switching electromagnet group is slidably inserted into the inner wall of the connecting shell through a connecting rod. A reset spring for forcing the switching electromagnet group to reset is fixedly mounted on the outer surface of the connecting rod, and a single toothed disk with an adsorption plate is fixedly mounted on one end of each of the two worm sleeves, and the double toothed disk meshes with the single toothed disk after moving, and the outer surface of the switching electromagnet group is magnetically connected to the outer surface of the adsorption plate of the single toothed disk.

[0009] Through the above technical scheme, the driving motor can selectively drive the two worm sleeves to rotate. After the double toothed disc is energized on one side of the switching electromagnet group, it can be magnetically connected to the adsorption plate on the energized side, and then the double toothed disc can be driven to move and engage with the single toothed disc on the magnetically connected side, thereby driving the worm sleeve to rotate. The switching electromagnet group is composed of two electromagnets with opposite electrodes.

[0010] Preferably, the clamping mechanism also includes a rotating rod, which is rotatably connected to the outer surface of the connecting shell through a bearing, one end of the rotating rod is engaged with a worm sleeve through a worm gear, one end of the rotating rod passes through the outer surface of the connecting shell and is fixedly installed with the rotating shell, and the rotating shell is rotatably connected to the outer surface of the connecting shell through a bearing.

[0011] Through the above technical solution, the worm wheel on one end of the rotating rod is engaged with a worm sleeve to drive the rotating rod to rotate, and the rotation of the rotating rod can drive the connecting shell to rotate, so as to facilitate all-round heat dissipation of the wheel hub.

[0012] Preferably, the inner wall of the connecting shell is rotatably connected to a transmission worm through a bearing, one end of the transmission worm is meshed with a worm sleeve through a worm wheel, the inner wall of the connecting shell is rotatably connected to a gear transmission rod through a bearing, the worm wheel of the gear transmission rod is meshed with the transmission worm, the outer surface of the rotating rod is slidably inserted with a gear ring sleeve, and the gear of the gear transmission rod is meshed with the gear ring sleeve.

[0013] Through the above technical solution, after the worm wheel on the transmission worm is meshed with a worm sleeve, the transmission worm can rotate, and the worm wheel and gear are fixedly installed on the gear transmission rod. The worm wheel is meshed with the transmission worm, and the rotation of the transmission worm drives the gear on the transmission worm to rotate, so that the gear ring sleeve on the rotating rod can move.

[0014] Preferably, the inner wall of the rotating shell is rotatably connected to a double-headed screw via a bearing, one end of the double-headed screw is meshed with the gear ring sleeve via a gear, both ends of the double-headed screw are threadedly connected to one end of the clamping jaw, and one end of the clamping jaw is slidably plugged into the outer surface of the rotating shell.

[0015] Through the above technical solution, the gear ring sleeve moves, which drives the gear on the double-headed screw to rotate and then drives the clamping claws to move relatively, so that the clamping claws can clamp the wheel hub.

[0016] Preferably, the protection device also includes a screw sleeve, the outer surface of the screw sleeve is rotatably connected to the outer surface of the rotating rod through a bearing, a driving gear disc is slidably inserted into one end of the rotating rod, a connecting spring is fixedly installed at one end of the rotating rod, one end of the connecting spring is fixedly installed at one end of the driving gear disc, and a driven gear disc is fixedly installed at one end of the screw sleeve, and the driven gear disc is meshed with the driving gear disc.

[0017] Through the above technical scheme, after the driven gear disc on the screw sleeve is meshed with the driving gear disc on the rotating shaft, the rotation of the rotating rod can drive the screw sleeve to rotate, thereby driving the threaded sleeve threadedly connected to the screw sleeve to move. After the threaded sleeve moves to the limited position, it cannot move, so that after the rotation of the screw sleeve is restricted, the extruded driving gear disc moves backward, and cannot drive the screw sleeve to rotate. The rotating rod can continue to drive the rotating shell to rotate, and then drive the wheel hub to rotate.

[0018] Preferably, the outer surface of the screw sleeve is threadedly connected with a threaded sleeve, the outer surface of one of the threaded sleeves is slidably plugged with a connecting electromagnet, the outer surface of one of the threaded sleeves is rotatably connected with a fixed bracket, one end of the connecting electromagnet is slidably plugged with the outer side surface of one of the fixed brackets and then magnetically connected to the inner wall of the fixed bracket, the outer surface of the threaded sleeve is fixedly installed with a telescopic spring that forces the connecting electromagnet to reset, and the inner wall of another fixed bracket is fixedly installed with the outer surface of another threaded sleeve.

[0019] Through the above technical scheme, a threaded sleeve is magnetically connected to a fixed bracket after the connecting electromagnet is energized and then slidably plugged in, so that the threaded sleeve and the fixed bracket are fixed, thereby being able to drive the two fixed brackets to move synchronously, so that the protective arc plate is close to the wheel hub that needs to be protected, supports the wheel hub, and wraps the outside of the wheel hub. After the connecting electromagnet is powered off, the fixation of the fixed bracket is released, so that the fixed bracket fixedly connected to the threaded sleeve can move, and the fixed bracket rotatably connected to the threaded sleeve cannot move, which is convenient for the extension and retraction of the scissors frame.

[0020] Preferably, the outer surface of the fixed bracket is hinged with a connecting scissors frame through a pin, one end of the connecting scissors frame is hinged with the outer surface of the protective arc plate through a pin, and the inner wall of the protective arc plate is rotatably connected with a ball.

[0021] Through the above technical scheme, the extension and retraction of the scissors frame can drive the protection arc plate to open and contract, so as to protect the outer surface of the wheel hub. After the diameter surrounded by the balls of the protection arc plate is adjusted to be the same as the diameter of the wheel hub, the protection arc plate is moved and slidably inserted into the outer surface of the wheel hub. After the electromagnet is connected and energized, the protection arc plate is driven to move and wrap the wheel hub. The balls facilitate the movement of the protection arc plate and the rotation of the wheel hub.

[0022] Preferably, a slide plate is fixedly mounted on the outer surface of the connecting shell, and one end of the protective arc plate is slidably plugged into the inner wall of the slide plate.

[0023] Through the above technical solution, the protective arc plate is limited by the groove of the slide plate and the connecting shell.

[0024] Preferably, the heat dissipation device also includes a telescopic pipe with an air inlet duct, the outer surface of the telescopic pipe is rotatably connected to a heat dissipation nozzle, a spherical end of the heat dissipation nozzle is connected to both ends of the telescopic pipe, a micro motor is fixedly installed on the outer surface of the telescopic pipe, and one end of the output shaft of the micro motor is meshed with the gear of the heat dissipation nozzle through a gear.

[0025] Through the above technical solution, the air inlet duct is connected to the fan, the air inlet end of the fan can draw the refrigerated air into the telescopic duct, the telescopic duct can open and contract in cooperation with the protective arc plate, and the micro motor drives the heat dissipation nozzle to deflect after starting, so as to achieve sufficient heat dissipation of the outer surface of the hub. One end of the heat dissipation nozzle is spherical in shape, which is convenient for deflection, and the two sides of the spherical shape are connected to the heat dissipation duct.

[0026] The beneficial effects of the present invention are:

[0027] 1. By setting a clamping device, the wheel hub is driven to rotate after clamping the wheel hub, which is convenient for heat dissipation. A driving motor can drive the rotation of the rotating rod and drive the gear ring sleeve on the rotating rod to move at the same time. The driving motor drives the rotation of the driving rod, and the two worm sleeves are rotated. The two worm sleeves are switched by double toothed discs and single toothed discs. After the movement of the double toothed disc is driven by the switching electromagnet group, it can be meshed with two single gears respectively, so that the two single gears can be selectively driven to rotate. The movement of the gear ring sleeve can drive the double-headed lead screw to rotate, so that the clamping claws can be driven to move relatively, and the wheel hub can be clamped. The rotation of the rotating rod drives the connecting shell to rotate through the meshing of the worm wheel and the worm sleeve to achieve all-round heat dissipation. These components and structures enable the clamping device to effectively clamp the magnesium wheel hub, and realize the rotation and movement of the wheel hub through the coordinated work of the driving components to meet the heat dissipation requirements and mobile work.

[0028] 2. A protective device is provided to support and fix the wheel hub and protect its exterior. After the protective arc plate is unfolded, the diameter can be adjusted to be the same as that of the wheel hub, so that the ball can contact the wheel hub to support the wheel hub. At the same time, the protective arc plate surrounds the outer surface of the wheel hub to protect the wheel hub. At the same time, the rotation of the rotating rod can drive the protective arc plate to unfold and move. A driving motor is used to drive multiple mechanisms, so that the wheel hub can be protected and supported, and the pressure of the clamping claws is reduced. This solves the problem that when the existing manipulator clamps the wheel hub, indentations are easily formed at the stress points, which affects the surface of the wheel hub. Secondly, the wheel hub has a certain temperature after being demolded, and employees may be easily burned if they accidentally touch it during clamping and filtering.

[0029] 3. By setting up a heat dissipation device, the wheel hub can be cooled during the clamping process. The refrigerated air can be delivered through the telescopic pipe. After the heat dissipation nozzle is deflected under the drive of the micro motor, the heat dissipation range can be increased and the heat dissipation effect can be accelerated, so that heat can be dissipated during the clamping process, which solves the technical problem that the existing wheel hub has a certain temperature after being demolded, and employees are easily burned by accidental touch during clamping and filtering.

[0047] Specifically, in order to drive the clamping jaws 36 to move relative or oppositely, the inner wall of the connecting shell 11 is rotatably connected to a transmission worm 32 through a bearing, and one end of the transmission worm 32 is meshed with a worm sleeve 22 through a worm gear.

[0049] like Figure 7-Figure 9 As shown, in order to support and protect the wheel hub, the protection device is located inside the connecting shell 11 and supports the clamped magnesium wheel hub. The protection device includes a protection arc plate 55. After the protection arc plate 55 moves, it fixes the clamped magnesium wheel hub.

[0050] Specifically, in order to drive the protection arc plate 55 to protect the wheel hub, the protection device also includes a screw sleeve 4. The outer surface of the screw sleeve 4 is rotatably connected to the outer surface of the rotating rod 3 through a bearing. A driving gear disc 41 is slidably inserted at one end of the rotating rod 3. A connecting spring 42 is fixedly installed at one end of the rotating rod 3.

A driven gear disc 43 is fixedly installed at one end of the screw sleeve 4, and the driven gear disc 43 is meshed with the driving gear disc 41.

[0051] Specifically, in order to control the protective arc plate 55 to selectively move or retract, the outer surface of the screw sleeve 4 is threadedly connected with a threaded sleeve 5, the outer surface of one threaded sleeve 5 is slidably inserted with a connecting electromagnet 51, the outer surface of one threaded sleeve 5 is rotatably connected with a fixed bracket 52, one end of the connecting electromagnet 51 is slidably inserted with the outer side surface of a fixed bracket 52 and then magnetically connected with the inner wall of the fixed bracket 52 to control the selective movement of the fixed bracket 52, the outer surface of the threaded sleeve 5 is fixedly installed with a telescopic spring 53 that forces the connecting electromagnet 51 to reset, and the inner wall of another fixed bracket 52 is fixedly installed with the outer surface of the other threaded sleeve 5.

In order to facilitate the support of the wheel hub, the inner wall of the protective arc plate 55 is rotatably connected with a ball 56.

[0053] Specifically, in order to limit the arc protection plate 55 , a slide plate 57 is fixedly installed on the outer surface of the connecting shell 11 , and one end of the arc protection plate 55 is slidably plugged into the inner wall of the slide plate 57 .

[0054] like Figure 10-11 As shown, in order to dissipate the heat of the wheel hub, a heat dissipation device is located on the outer surface of the protective device, and the heat dissipation device includes a heat dissipation nozzle 61. The deflection of the heat dissipation nozzle 61 dissipates the heat of the clamped magnesium wheel hub.

[0055] Specifically, in order to automatically dissipate the heat of the wheel hub, the heat dissipation device also includes a telescopic pipe 6 with an air inlet duct. The outer surface of the telescopic pipe 6 is rotatably connected to a heat dissipation nozzle 61. One end of the heat dissipation nozzle 61 is spherical for easy deflection. The spherical end of the heat dissipation nozzle 61 is connected to both ends of the telescopic pipe 6. A micro motor 62 is fixedly installed on the outer surface of the telescopic pipe 6. In order to increase the heat dissipation range, one end of the output shaft of the micro motor 62 is meshed with the gear of the heat dissipation nozzle 61 through a gear.

[0056] Working principle: when the wheel hub needs to be clamped, the connecting shell 11 is driven to be adjusted by the manipulator base 1, and the clamping claw 36 can be driven to approach the wheel hub that needs to be demolded. After the driving motor 2 in the connecting shell 11 drives the driving rod 21 to rotate, the switching electromagnet group 24 is energized and magnetically connected with a worm sleeve 22. After the double toothed disc 23 is meshed with a single toothed disc 26, the rotation of the driving rod 21 drives a worm sleeve 22 to rotate. After the rotation of the worm sleeve 22, the worm sleeve 22 drives the transmission worm 32 to rotate through the worm gear. The transmission worm 32 can drive the gear transmission rod 33 to rotate through the worm gear. The rotation of the gear transmission rod 33 can drive the gear ring sleeve 34 to move on the rotating rod 3 through the gear, thereby driving the double-headed screw 35 meshing therewith to rotate. After the rotation of the double-headed screw 35 drives the clamping claw 36 to move relatively, the central axis of the wheel hub can be clamped.

[0057] After the manipulator base 1 adjusts the connection housing 11 to move, the electromagnet group 24 is switched off at the same time, and reset under the action of the reset spring 25, and the electromagnet on the other side of the electromagnet group 24 is switched on, and adsorbed with another single toothed disc 26, the double toothed disc 23 is meshed with the single toothed disc 26, and the worm sleeve 22 on the rotating rod 3 is driven to rotate, and the rotating rod 3 is driven to rotate through the worm gear, and the rotating rod 3 drives the rotating housing 31 to rotate, and drives the clamped wheel hub to rotate;

[0058] At the same time, the rotation of the rotating rod 3 can drive the driving gear plate 41 to rotate, and the driving gear plate 41 drives the driven gear plate 43 to rotate, thereby driving the screw sleeve 4 to rotate. After the threaded sleeve 5 moves, it drives the fixed bracket 52 fixed thereto to move. The other threaded sleeve 5 rotates, pulls the connecting scissors frame 54 to deflect, pulls the protective arc plate 55 to shrink, so that the diameter of the roller of the protective arc plate 55 is the same as the diameter of the wheel hub, and after the connecting electromagnet 51 is energized, the connecting electromagnet 51 is plugged into a fixed bracket 52, so that the threaded sleeve 5 and the fixed bracket 52 are connected. The bracket 52 is connected, and the two threaded sleeves 5 can rotate, driving the protective arc plate 55 to move, close to the wheel hub, and surrounding the outer surface of the wheel hub. After the fixed bracket 52 and the protective arc plate 55 are limited, the screw sleeve 4 cannot rotate. After the driven gear disc 43 squeezes the driving gear disc 41, the driving gear disc 41 can squeeze the connecting spring 42, and the driving gear disc 41 cannot drive the driven gear disc 43 to rotate. After the fan delivers cold air to the telescopic pipe 6, it is started by the micro motor 62, driving the heat dissipation nozzle 61 to deflect, and the outer surface of the wheel hub is cooled.
