DETAILED DESCRIPTION

[0035] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0036] A floating support device for cutting processing, see Figure 1-4 As shown, it includes: a fixing seat 100, a rising piston 200, a spring 300, a cylinder 400, a movable locking block 500 and a limiting shaft 600.

[0037] The fixing seat 100 is used as a carrier, and the components such as the rising piston 200, the spring 300, the cylinder 400, the movable locking block 500 and the limit shaft 600 can be installed on the fixing seat 100, and then the entire floating support device for cutting processing is installed on the corresponding processing equipment, which is more convenient for installation; the fixing seat 100 can have a variety of shapes and is applied to the processing equipment. The fixing seat 100 is generally made of high-hardness metal material and should not be deformed or damaged; Figure 2 As shown, in this embodiment, the fixing seat 100 is in a rectangular parallelepiped shape, a moving channel 101 is formed in the fixing seat 100, and the rising piston 200 is installed in the moving channel 101 and rises under the elastic force of the spring 300;

[0038] The first end of the lifting piston 200 is located in the moving channel 101, and the second end extends out of the moving channel 101 to support the workpiece. The lifting piston 200 is adapted to be installed in the moving channel 101. Figure 2 It can be seen that at least the top opening end of the moving channel 101 is rectangular, so the rising piston 200 is also set to be rectangular; and the rising piston 200 is in contact with the inner wall surface of the moving channel 101 inside the moving channel 101; the first end of the rising piston 200 is set to be a supporting cylinder 220, and the supporting cylinder 220 extends out of the moving channel 101 to support the workpiece.

[0039] The spring 300 mainly provides elastic force to the rising piston 200, and the elastic force is opposite to the gravity of the workpiece; the spring 300 can be installed in a variety of ways, such as the spring 300 can be sleeved on the rising piston 200, with its upper end limited by the rising piston 200 and its lower end limited by the inner wall of the moving channel 101; or Figure 4 As shown, an inner concave portion 230 is formed in the ascending piston 200 from the bottom to the top, one end of the spring 300 is restricted in the inner concave portion 230 , and the other end extends out of the inner concave portion 230 and is supported on the inner bottom of the moving channel 101 .

[0040] Furthermore, if Figure 1-2 As shown, the fixing seat 100 is provided with a strip groove, and a pin is provided on the peripheral side of the lifting piston 200, and the pin is clamped in the strip groove to limit the moving path of the lifting piston 200; or

[0041] The fixing seat 100 is provided with a pin shaft 102 , and a strip groove 210 is provided on the circumference of the lifting piston 200 . The pin shaft 102 is clamped in the strip groove 210 to limit the moving path of the lifting piston 200 .

[0042] like Figure 3-4 As shown, in this embodiment, a pin shaft 102 is provided on the fixed seat 100, and a vertical strip groove 210 is provided on the circumference of the rising piston 200. The moving stroke of the rising piston 200 is limited by the length of the strip groove 210. When the pin shaft 102 moves to the uppermost end of the strip groove 210, the rising piston 200 reaches the maximum descending stroke; when the pin shaft 102 moves to the lowermost end of the strip groove 210, the rising piston 200 reaches the maximum rising stroke, at the maximum rising stroke position, the spring 300 still has an elastic effect on the rising piston 200.

[0043] Furthermore, the movable locking block 500 is limited in the fixed seat 100 by a limiting shaft 600 and can rotate around the limiting shaft 600. The first end of the movable locking block 500 is connected to the output shaft 410, and the second end acts on the rising piston 200.

[0044] Specifically, an installation cavity 103 is formed inside the fixed base 100, and the installation cavity 103 is connected to the movable channel 101; the cylinder 400 is installed on the fixed base 100, and the output shaft 410 extends into the installation cavity 103; the movable locking block 500 is located in the installation cavity 103, and there is enough space in the installation cavity 103 for the movable locking block 500 to rotate.

[0045] A long strip-shaped limiting groove 510 is disposed at the first end of the movable locking block 500 . A connecting shaft 411 is disposed on the output shaft 410 . The connecting shaft 411 passes through the limiting groove 510 .

[0046] When the cylinder 400 drives the output shaft 410 to move, the movable locking block 500 is driven to rotate around the limit shaft 600 through the output shaft 410; specifically, when the cylinder 400 drives the output shaft 410 to move forward, the movable locking block 500 rotates forward around the limit shaft 600, and the second end of the movable locking block 500 leaves the rising piston 200; when the cylinder 400 drives the output shaft 410 to move reversely, the movable locking block 500 rotates reversely around the limit shaft 600, and the screw head 4111 of the connecting shaft 411 presses the surface of the movable locking block 500, and the second end of the movable locking block 500 is pressed tightly against the rising piston 200, and the rising piston 200 is pressed against the moving channel 101.

[0047] like Figure 3 As shown, Figure 3 Schematic diagram of the cylinder 400 driving the output shaft 410 to move in the reverse direction. At this time, the movable locking block 500 presses the surface of the rising piston 200, so that the rising piston 200 cannot move vertically (i.e. Figure 3 moving perpendicular to the paper in orientation);

[0048] At this time, if the cylinder 400 drives the output shaft 410 to move forward, that is, the output shaft 410 extends to the right, the movable locking block 500 rotates forward around the limit shaft 600, that is, rotates counterclockwise, and the second end of the movable locking block 500 releases the rising piston 200;

[0049] It can be understood that Figure 3 The orientation indicates that when the cylinder 400 drives the output shaft 410 to move to the right, the movable locking block 500 rotates counterclockwise around the limit shaft 600, and the second end of the movable locking block 500 releases the rising piston 200; when the cylinder drives the output shaft 410 to move to the left, the movable locking block 500 rotates clockwise around the limit shaft 600, and the second end of the movable locking block 500 presses the rising piston 200 more tightly.

[0050] Furthermore, the installation cavity 103 passes through the first side surface 110 and the second side surface 120 of the fixing seat 100, and the first side surface 110 and the second side surface 120 are positioned opposite to each other; protective plates 130 are respectively provided on the first side surface 110 and the second side surface 120 to effectively prevent dust, garbage, etc. from entering and avoid affecting use.

[0051] like Figure 4 As shown, when in use, the output shaft 410 of the cylinder 400 first moves forward, the movable locking block 500 releases the rising piston 200, and then the rising piston 200 moves upward under the action of the spring 300, and contacts the workpiece to generate a tightening force; finally, the cylinder 400 moves in the opposite direction to tighten the movable locking block 500, so that the movable locking block 500 presses the rising piston 200 again, so that the rising piston 200 is positioned at the current height, and the support stability is strong.

[0052] A processing equipment includes a floating support device for cutting processing. In the working table of the processing equipment, according to the different numbers of processing stations, different processing requirements, etc., multiple floating support devices for cutting processing can be set on the working table to support the workpiece.

[0053] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
