[0028] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0029] like Figures 1 to 3 As shown, the high temperature environment resistant manipulator of the present invention comprises a cylinder 1, an extension shaft 2, an air cooling mechanism and a clamping jaw; wherein the cylinder 1 is mounted at one end of the extension shaft 2, and the clamping jaw is mounted at the other end of the extension shaft 2; the air cooling mechanism is located inside the extension shaft 2, and the clamping jaw is connected to the cylinder 1. The clamping jaw is driven to open or close by the cylinder 1 to perform tasks such as grasping and operation; and the clamping jaw is cooled by the air cooling mechanism at the same time.

[0030] Specifically, the cylinder 1 includes a cylinder barrel 101, a front cover 102, a rear cover 103, a piston 104 and a first piston rod 105; wherein the cylinder barrel 101 is a cylindrical body with openings at both ends, the front cover 102 encloses the front end opening of the cylinder barrel 101, and the rear cover 103 encloses the rear end opening of the cylinder barrel 101; the front cover 102, the rear cover 103 and the cylinder barrel 101 enclose a sliding space 106. The rear cover 103 is installed with a connecting rod 107, and the connecting rod 107 is located in the sliding space 106. The first piston rod 105 is provided with a connecting end and a pushing end, wherein the connecting end extends into the sliding space 106 and is provided with a first sliding groove 108, and the connecting rod 107 extends into the first sliding groove 108; the pushing end passes through the front cover 102 and is mechanically connected to the air cooling mechanism, so that part of the first piston rod 105 is located in the sliding space 106. The piston 104 is slidably installed on the connecting rod 107 and is connected to the connecting end of the first piston rod 105.

[0031] Furthermore, a first air hole 109 is opened at a position of the cylinder 101 corresponding to the rear cover, and a second air hole 110 is opened at a position corresponding to the front cover, and both the first air hole 109 and the second air hole 110 are connected to the sliding space 106 .

[0032] When the first air hole 109 is ventilated, the gas pushes the first piston rod 105 to slide forward relative to the connecting rod 107, thereby pushing the connecting end of the first piston rod 105, causing the first piston rod 105 to slide forward, and the pushing end pushes the air cooling mechanism forward, and then the air cooling mechanism pushes the clamping jaw forward to open; when the second air hole 110 is ventilated, the gas pushes the piston 104 to slide backward along the connecting rod 107, driving the connecting end of the first piston rod 105 to slide backward, causing the pushing end of the first piston rod 105 to slide backward, driving the air cooling mechanism to slide backward, and thus driving the clamping jaw to close.

[0033] like Figure 3 and Figure 4As shown, the air cooling mechanism includes an adapter 3, a cooling pipe 4 and a nozzle 5; wherein the pushing end of the first piston rod 105 is mechanically connected to one end of the cooling pipe 4 through a pin 6, and the nozzle 5 is installed at the other end of the cooling pipe 4. The adapter 3 is sleeved outside the connection between the cooling pipe 4 and the pushing end, and the adapter 3 is provided with a hot air outlet 301, and the hot air outlet 301 is connected to the cooling pipe 4. A vortex chamber 501 is provided in the nozzle 5, and the vortex chamber 501 is connected to the cooling pipe 4, and a vortex cyclone component 7 is installed in the vortex chamber 501. Specifically, the vortex cyclone component 7 includes a hollow connecting shaft 701 and a cyclone blade 702 installed on the connecting shaft, and the vortex chamber 501 is provided with a connecting groove 502, and the connecting shaft 701 and the connecting groove 502 are connected by threads.

[0034] Further, the nozzle 5 is also provided with an air inlet end and an air outlet end. The air inlet end is provided with an air inlet 503, which is connected to the vortex chamber 501 and is connected to the outside. The air outlet end is mechanically connected to the clamping claw, and the air outlet end is provided with a cold air outlet 504. The cold air outlet 504 is connected to the connecting groove 502, and the cold air outlet 504 is connected to the clamping claw. The cold air outlet 504 is connected to the vortex chamber 501 through the connecting shaft 701.

[0035] The compressed air enters from the air inlet 503, pushing the cyclone blades 702 of the vortex cyclone member 7 to rotate at a high speed. The compressed air generates centrifugal force through the cyclone blades 702, so that the compressed air enters the cooling tube 4 in a tangential form, and then rotates and advances in the cooling tube 4 in a spiral manner; when the compressed air rotates at a high speed (1 million revolutions per minute) in the cooling tube 4, it is divided into two parts by the vortex; the inner layer of air in the center of the cooling tube 4 has a large rotation angular velocity and rubs against the outer layer of air near the tube wall of the cooling tube 4, transferring heat to the outer layer of air, so that the energy of the inner layer of air in the center of the cooling tube 4 is weakened, the speed is slowed down, and the temperature is reduced. After the cooled cold air encounters the first piston rod 105, it rebounds and turns, passes through the connecting shaft 701, and flows out from the cold air outlet 504 of the nozzle 5, blowing towards the clamping jaws to cool the clamping jaws; and the outer layer of hot air near the tube wall of the cooling tube 4 flows out from the hot air outlet 301, taking away the heat of the extension shaft 2, ensuring the stability of the structure and performance of the manipulator and improving the operating accuracy.

[0036] like Figures 1 to 3As shown, the clamp includes a second piston rod 8, two fingers 9 and a mounting shell 10; one end of the second piston rod 8 is connected to the air outlet end of the nozzle 5, so that the cold air outlet 504 is connected to the second piston rod 8; the other end is provided with a push head 801. The mounting shell 10 is provided with a mounting groove 11, and the other end of the second piston rod 8 passes through the mounting shell 10, and the push head 801 is accommodated in the mounting groove 11. The two fingers 9 are installed in the mounting groove 11, and the two fingers 9 are arranged oppositely; the push head 801 is located between the two fingers 9. The push head 801 and the two fingers 9 are connected by an oblique wedge structure; specifically: the push head 801 is arranged in an isosceles trapezoidal shape, and the two oblique sides of the push head 801 are provided with a push block 802; each finger 9 is provided with a second slide groove 901, and each push block 802 is installed in each second slide groove 901. When the second piston rod 8 pushes the push head 801 , the two push blocks 802 slide in the two second slide grooves 901 respectively, thereby pushing the two fingers 9 to open, and converting the radial movement of the second piston rod 8 into the axial movement of the two fingers 9 .

[0037] In addition, a slot 803 is provided near the two push blocks 802 of the push head 801, and each slot 803 is arranged parallel to the corresponding push block 802. A clamping boss 902 is provided in each second slide groove 901, and when each push block 802 is installed in each second slide groove 901, the clamping boss 902 is clamped into the slot 803, thereby effectively connecting the second piston rod 8 with the two fingers 9, and preventing the two fingers 9 from falling off from the push head 801.

[0038] In addition, a temperature sensor 12 is provided on the mounting shell 10 to sense the temperature of the clamping jaws. When the temperature of the clamping jaws exceeds a preset temperature (40° C.), compressed air is introduced through the air inlet 503 . When the temperature of the clamping jaws is lower than 20° C., ventilation is stopped.

[0039] In addition, a first air vent 804 is provided at one end of the second piston rod 8 close to the push head 801 , second air vents 903 are provided on both fingers 9 , and a third air vent 13 is provided on the mounting shell 10 . The third air vent 13 is arranged corresponding to the second air vent 903 , and the first air vent 804 is connected to the second air vent 903 .

[0040] After the cold air is blown out from the cold air outlet 504, it passes through the second piston rod 8, blows into the mounting groove 11 from the first vent hole 804, and then blows out from the third vent hole 13 and the second vent hole 903 in sequence, thereby taking away the heat of the entire clamp, playing a role in cooling the clamp, ensuring that the clamp can operate in an appropriate working temperature environment (20-40°C), effectively avoiding the clamp from operating in an ultra-high temperature environment (700-800°C) for a long time, ensuring the clamping stability and structural stability of the clamp, thereby improving operating accuracy, improving product yield, and allowing the clamp to be used in occasions that meet high-precision requirements.

[0041] like Figure 2 , Figure 3 and Figure 5 As shown, Figure 5 It is a schematic diagram of the open state of two fingers 9. At this time, the first air hole 109 is ventilated, pushing the first piston rod 105 to slide forward relative to the connecting rod 107, thereby pushing the connecting end of the first piston rod 105, causing the first piston rod 105 to slide forward, and the pushing end pushes the cooling tube 4 forward, and then the cooling tube 4 pushes the second piston rod 8 forward, so that the two push blocks 802 of the push head 801 slide forward in the second slide grooves 901 of the two fingers 9 respectively, to open the two fingers 9.

[0042] like Figure 2 , Figure 3 and Figure 6 As shown, Figure 6 It is a schematic diagram of the closed state of two fingers 9. At this time, the second air hole 110 is ventilated, pushing the piston 104 to slide backward along the connecting rod 107, driving the connecting end of the first piston rod 105 to slide backward, so that the pushing end of the first piston rod 105 slides backward, driving the cooling tube 4 to slide backward, thereby driving the second piston rod 8 to slide backward, so that the two push blocks 802 of the push head 801 slide backward in the second slide grooves 901 of the two fingers 9 respectively, driving the two fingers 9 to close.

[0043] like Figure 3 As shown, in addition, one end of the extension shaft 2 is connected to the cylinder barrel 101 through the asbestos-free plate 14 and the connecting plate 15, and the other end is connected to the mounting shell 10, thereby realizing the connection between the extension shaft 2 and the cylinder 1 and the clamping claw.

[0044] Furthermore, the extension shaft 2 is provided with a first through hole 201 and a second through hole 202 ; wherein the air inlet 503 of the nozzle 5 is located at the first through hole 201 , and the hot air outlet 301 is located at the second through hole 202 .

[0045] In summary, the high temperature resistant robot of the present invention has the following advantages:

[0046] 1. The air cooling mechanism is set to cool the jaws, which can effectively prevent the jaws from working in an ultra-high temperature (700-800°C) environment for a long time, ensure that the jaws can work in a suitable working temperature (20-40°C) environment, ensure the clamping stability and structural stability of the jaws, thereby improving the operating accuracy and product yield, so that the jaws can be used in occasions with high precision requirements.

[0047] 2. A vortex chamber 501 is provided in the nozzle 5, and a vortex cyclone member 7 is provided in the vortex chamber 501; when the compressed air pushes the vortex cyclone member 7, centrifugal force is generated by the vortex cyclone member 7, so that the compressed air enters the cooling tube 4 in a tangential form, and then rotates and advances in the cooling tube 4 in a spiral manner; when the compressed air rotates at a high speed (1 million revolutions per minute) in the cooling tube 4, the compressed air is divided into two parts by the vortex; the inner layer of air located at the center of the cooling tube 4 has a large rotation angular velocity and rubs against the outer layer of air near the tube wall of the cooling tube 4, transferring heat to the outer layer of air, so that the energy of the inner layer of air at the center of the cooling tube 4 is weakened, the speed is slowed down, and the temperature is reduced. After the cooled cold air encounters the first piston rod 105, it rebounds and turns, passes through the connecting shaft 701, and flows out from the cold air outlet 504 of the nozzle 5, blows toward the clamp, and cools the clamp; and the outer layer of hot air near the tube wall of the cooling tube 4 flows out from the hot air outlet 301, taking away the heat of the extension shaft 2, thereby ensuring the stability of the structure and performance of the manipulator and improving the operation accuracy.

[0048] 3. By setting a slot 803 at a position of the push head 801 close to the two push blocks 802, a snap-in boss 902 is set in each second slide groove 901; when each push block 802 is installed in the corresponding second slide groove 901, the snap-in boss 902 is snapped into the slot 803, thereby effectively preventing the two fingers 9 from falling off the push head 801.
