Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, a pressing platform device capable of being accurately adjusted comprises a base, wherein a servo displacement system is transversely arranged on the base, and an X-axis moving bottom plate 3 is arranged on the servo displacement system; the servo displacement system is an electric cylinder, the X-axis moving bottom plate 3 is fixedly arranged on a sliding block of the electric cylinder, and the electric cylinder starts to drive the sliding block to move along the X-axis (left and right) direction so as to drive the X-axis moving bottom plate 3 to accurately move left and right.
A left pressing device 1 and a right pressing device 2 are fixedly arranged above the left part and the right part of the X-axis moving bottom plate 3 respectively, and the left pressing device 1 and the right pressing device 2 have the same structure; the left pressing device 1 comprises a Y-axis moving unit 7, a Z-axis moving unit 8 and a locking flexible pressing block 9, the Y-axis moving unit 7 is arranged on the X-axis moving base plate 3, the Z-axis moving unit 8 is arranged on the Y-axis moving unit 7, and a clamping platform 6 is fixedly arranged at the top of the Z-axis moving unit 8.
A pressing block fixing frame 5 is arranged on the clamping platform 6, a pressing block driving cylinder 4 is fixedly arranged at the top of the pressing block fixing frame 5, the output end of the pressing block driving cylinder 4 downwards penetrates through the pressing block fixing frame and then is connected with a locking flexible pressing block 9, the locking flexible pressing block 9 is positioned above the clamping platform 6, and the locking flexible pressing block 9 is made of a soft material; the pressing block driving cylinder drives the locking flexible pressing block to move up and down so as to compress or loosen the balloon catheter in the V-shaped groove.
A V-shaped groove 10 is formed in the top surface of the clamping platform 6, and the balloon catheter is placed in the V-shaped groove 10; a circular depressed area 11 is arranged in the center of the top surface of the clamping platform 6, the outline of the depressed area corresponds to the outer circle of the locking flexible pressing block 9, the locking flexible pressing block 29 is driven by the pressing block driving cylinder 24 to be pressed in the depressed area, and the balloon catheter placed in the V-shaped groove is pressed and fixed.
The Y-axis moving unit and the Z-axis moving unit are commercially available knob type moving units, a lead screw in the moving unit is driven to rotate by rotating a knob, and rotary motion is converted into linear motion, so that the clamping platform is moved. The arrangement of the Y-axis moving unit and the Z-axis moving unit enables the clamping platform to move 10mm in the Z-axis (up-down) direction and the Y-axis (front-back) direction in a positive and negative mode, and the clamping platform is used for accurately adjusting the position of the balloon catheter.
The above embodiments are not intended to limit the present invention, and the present invention is not limited to the above examples, and the technical personnel in the technical field are in the present invention, which can also belong to the protection scope of the present invention.
