Detailed Description
The invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1 and 2, the crucible conveying gripper with high stability of the invention comprises a frame plate 2 and a piston cylinder 6 arranged on the frame plate 2.
The output rod of the piston cylinder 6 is collinear with the axis of the conical crucible 1.
Four claw plates 21 are axially symmetrically arranged at the bottom of the frame plate 2, elastic rolling claws 3 which can stretch and retract along the radial direction of the conical crucible 1 are arranged on the claw plates 21, a sliding sleeve 4 is arranged at the end part of an output rod of the piston cylinder 6 in a sliding manner, an axial spring 5 is arranged in the sliding sleeve 4, and a hyperbolic cone 7 is fixedly arranged at the other end of the sliding sleeve 4. The radius of the lower bottom surface of the hyperbolic cone 7 is equal to the outer radius of the upper end surface of the conical crucible 1, so that the elastic rolling claws 3 can smoothly roll from the surface of the hyperbolic cone 7 to the surface of the conical crucible 1.
The elastic rolling jaw 3 comprises a radial sliding plate 33 passing through the jaw plate 21 along the radial direction of the conical crucible 1, a radial spring 32 sleeved on the radial sliding plate 33, a radial spring baffle plate 31 fixedly arranged on one end of the radial sliding plate 33 far away from the conical crucible 1, a roller shaft 35 rotatably arranged on one end of the radial sliding plate 33 close to the conical crucible 1, and a curve roller 34 fixedly arranged on the roller shaft 25. The cross section of the radial sliding plate 33 is rectangular, so that the radial sliding plate 33 can be effectively prevented from rotating during sliding, namely the rigidity value of the radial spring 32 cannot be changed when the radial sliding plate 33 slides; the radial sliding plate 33 is made of teflon, so that sliding friction force and sliding noise can be reduced; the curve roller 34 is made of non-metal material, and the friction coefficient of the curve roller is not less than twice of the friction coefficient of Teflon, so that the curve roller 34 can roll on the conical crucible 1.
Two ends of the radial spring 32 are respectively connected with the radial spring baffle 31 and the claw plate 21, and the radial spring 32 is always in a stretching stress state; the curved rollers 34 are composed of hyperbolic half rollers a341 and hyperbolic half rollers B342 which have the same structure, and the hyperbolic half rollers a341 and the hyperbolic half rollers B342 are symmetrically positioned on two sides of the radial sliding plate 33; the generatrix of the rolling surface formed by the hyperbolic half roller A341 and the hyperbolic half roller B342 is a hyperbola. The radial sliding plate 33 tends to move towards the tapered crucible 1 under the pulling force of the radial spring 32, and the radial pressure of the curve roller 34 on the tapered crucible 1 is in direct proportion to the deformation of the radial spring 32; when the curved roller 34 rolls up and down along the hyperbolic cone 7 or the conical crucible 1, the radial sliding plate 33 slides in the radial direction of the conical crucible 1.
The axial spring 5 is a tension and compression spiral spring, and two ends of the axial spring are respectively connected with an output rod and a hyperbolic cone 7 in the piston cylinder 6. An output rod of the piston cylinder 6 moves up and down, and drives the hyperbolic cone 7 to move up and down through the axis spring 5, so as to drive the hyperbolic roller 34 to move along the radial direction of the conical crucible 1.
Preferably, the material of the hyperbolic cone 7 is teflon, which on the one hand reduces the rolling friction between the curved roller 34 and the hyperbolic cone 7 and on the other hand eliminates rolling noise. The hyperbolic character of the hyperbolic cone 7 on the one hand helps the curvilinear roller 34 to return to the initial state of the axial spring 5 at the minimum of potential energy and on the other hand makes it possible to make the curvilinear roller 34 easily roll from the hyperbolic cone 7 onto the outer surface of the tapered crucible 1.
Preferably, the deformation amount of the axial spring 5 in the operation process of the piston cylinder 6 is not more than one half of the radius of the curve roller 34, so that the lower end face of the hyperbolic cone 7 is tightly pressed on the upper end of the conical crucible 1 when the elastic rolling claw 3 clamps the conical crucible 1, the shaking of the conical crucible 1 caused by external vibration in the transportation process of the conical crucible 1 is reduced, and the stability of the conical crucible 1 is improved.
Preferably, the curved roller 34 maintains two-point contact while rolling up and down along the outer surface of the tapered crucible 1. Therefore, when the four elastic rolling claws 3 simultaneously grip the tapered crucible 1, eight-point contact pressure can be formed to the tapered crucible 1, thereby improving the stability of the grip of the tapered crucible 1.
Preferably, the output rod of the piston cylinder 6 is the longest and the curved roller 34 is located in the middle of the hyperbolic cone 7 when the deformation amount of the axial spring 5 is zero.
The working process and working principle of the invention are as follows: firstly, the crucible conveying mechanical claw is arranged on a mechanical arm, then the mechanical arm is adjusted, so that the mechanical claw is positioned right above the conical crucible 1 to be conveyed, at the moment, the output rod of the piston cylinder 6 is the longest, the deformation of the axial spring 5 is zero, the curve roller 34 is just positioned in the middle of the hyperbolic cone 7, and the lower end face of the hyperbolic cone 7 is in free contact with the upper end of the conical crucible 1.
The crucible conveying mechanical claw is driven to descend by controlling the descending of the mechanical arm, meanwhile, the piston cylinder 6 is started to enable the output rod to retract slowly, the movement speed of the output rod in the piston cylinder 6 is equal to the descending speed of the mechanical claw, namely, the lower end face of the hyperbolic cone 7 always butts against the upper end of the conical crucible 1.
During the process that the output rod of the piston cylinder 6 is gradually retracted, the curve roller 34 rolls downwards along the generatrix of the hyperbolic cone 7, the radial sliding plate 33 moves towards the direction far away from the conical crucible 1, and the pressure of the radial spring 32 is gradually increased; then, the curved roller 34 rolls from the hyperbolic cone 7 to the outer surface of the tapered crucible 1, and since the upper part of the tapered crucible 1 is thick and the lower part is thin, when the curved roller 34 rolls on the generatrix of the tapered crucible 1, the radial sliding plate 32 moves towards the direction close to the tapered crucible 1, the pressure of the radial spring 32 is gradually reduced, but the curved roller 34 is still tightly pressed on the tapered crucible 1.
When the output rod of the piston cylinder 6 reaches the shortest state, the curve roller 34 is positioned at the middle upper part of the conical crucible 1, and the piston cylinder 6 stops working. Because the diameter of the upper part of the conical crucible 1 is large, the diameter of the lower part of the conical crucible 1 is small, and the radial spring 32 is always in a stretching state, the curve roller 34 has a tendency of rolling downwards relative to the conical crucible 1, at the moment, because the top part of the conical crucible 1 is tightly pressed on the hyperbolic cone 7, the rolling friction force of the curve roller 34 can lock the conical crucible 1, and the conical crucible 1 is prevented from axially sliding due to external vibration.
When the mechanical arm drives the crucible conveying mechanical claw to convey the conical crucible 1 to a destination, namely the bottom surface of the conical crucible 1 is in a supporting state, for example, the bottom surface of the conical crucible is in contact with a table top, the mechanical arm drives the crucible of the invention to move upwards, meanwhile, an output rod of the piston cylinder 6 extends outwards gradually, the speeds of the mechanical claw and the piston cylinder are the same, namely, the lower end surface of the hyperbolic cone 7 always butts against the upper end of the conical crucible 1.
During the process that the output rod of the piston cylinder 6 is gradually extended, the curve roller 34 rolls upwards along the conical crucible 1 until the curve roller rolls to the middle part of the hyperbolic cone 7, namely the output rod reaches the longest state. Thereby completing the conveyance of the tapered crucible 1.
In the conveying process of the conical crucible 1, although the mechanical arm moves, the conical crucible 1 is stressed at eight points on the same circumference, and the lower end face of the hyperbolic cone 7 is always pressed against the upper end of the conical crucible 1 under the action of the axis spring 5, so that the conical crucible 1 cannot shake, and the scattering of materials in the conical crucible 1 is avoided. When the crucible conveying mechanical claw is in a non-working state, the curve roller 34 is just positioned in the middle of the hyperbolic cone 7; the axial spring 5 respectively generates tensile deformation and compression deformation in the up-and-down movement process of an output rod of the piston cylinder 6, so that the surplus energy of the conical crucible 1 during grabbing and releasing placement can be absorbed, and the stability during grabbing or releasing is improved.
The above is only a specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through creative efforts should fall within the scope of the present invention.
