Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

FIG. 1 is a schematic view of a valve plate to be machined according to the present invention; therefore, the valve plate is roughly rectangular, and two through holes are required to be processed on the valve plate along the width direction of the valve plate; therefore, the valve plate is pressed and fixed from four sides and up and down.

A valve plate clamp comprises a base plate 1, a clamping mechanism 2 installed on the base plate, side supporting blocks 3, a first side pressing mechanism 4 and a second side pressing mechanism 5, wherein the clamping mechanism 2 is provided with three groups, the three groups of clamping mechanisms 2 are distributed on the base plate 1 in a triangular mode, the upper surface and the lower surface of a valve plate are supported and clamped by the clamping mechanism 2, the side supporting blocks 3 are installed on two adjacent sides of the valve plate, the first side pressing mechanism 4 is located on one machining side (cutter feeding side) of the valve plate, and the second side pressing mechanism 5 is arranged on the other side of the valve plate.

Specifically, as shown in fig. 1 to 5, the clamping mechanism 2 acts on the upper and lower surfaces of the first side, the second side and the third side of the valve plate, respectively. The side supporting blocks 3 are arranged in three blocks and act on a third side edge and a fourth side edge respectively, wherein two side supporting blocks 3 are arranged at the third side edge and are positioned at two ends of the third side edge; a side supporting block is arranged in the middle of the fourth side. Two first side hold-down mechanisms 4 act on the first side edge of the valve plate, and a second side hold-down mechanism 5 acts on the second side edge of the valve plate. When the valve plate clamping device is used, the valve plate is conveyed to the clamp and is supported by the clamping mechanism 2; then the valve plate is pushed forwards towards the Y axis through a second side pressing mechanism 5 to be tightly propped against a side supporting block 3 positioned on the fourth side, and then the second pressing mechanism 5 is reset; then the first side pressing mechanism 4 pushes the valve plate to move forward towards the X axis, so that the valve plate is tightly propped against the side supporting block 3 positioned on the third side edge, and the second pressing mechanism 5 is driven to be pressed on the valve plate; and finally, clamping the upper surface and the lower surface of the valve plate through a clamping mechanism 2.

As shown in fig. 1-5 and fig. 7-8, the first side pressing mechanism 4 includes a first mounting seat 41, a first pressing block 42 and a first oil cylinder 43, the first pressing block 42 is in an L-shaped structure, one end of the first pressing block 42 is provided with a pressing part 421, the first pressing block 42 is hinged to the first mounting seat 41 through a rotating shaft, and the first oil cylinder 43 acts on the other end of the first pressing block 42. When the valve is used, the first oil cylinder 43 is driven to move towards the Z axis forward direction, and the first pressing block 42 is pushed to rotate around the rotating shaft so as to drive the jacking portion 421 to move towards the valve plate. In an embodiment, the second side pressing mechanism 5 includes a third mounting seat 51 and a third cylinder 52 horizontally disposed on the third mounting seat 51, and an output end of the third cylinder 52 is provided with a pressing block 53. The pressing block 53 is driven by the third cylinder 52 to press the valve plate. In the drilling process, the cutting force which is continuously rotated can be generated, so that the valve plate can shake in a Y-Z plane, and the valve plate cannot be stably arranged on the clamp because a gap exists between the body of the oil cylinder and the piston rod. And the first side pressing mechanism 4 is adopted to avoid the existence of the gap, and the possibility that the valve plate shakes due to the existence of the oil cylinder gap is avoided.

In one embodiment, as shown in fig. 1-6, the clamping mechanism 2 includes a bottom support base 21 and a clamping assembly, the bottom support base 21 is located below the valve plate to support the valve plate, and the clamping assembly acts on the top of the bottom support base 21 to clamp the valve plate up and down through the combined action of the clamping assembly and the bottom support base 21. The pressing assembly comprises a second mounting seat 22, a second pressing block 23, a connecting rod 24 and a second oil cylinder 25, one end of the connecting rod 24 is hinged to the second mounting seat 22, the other end of the connecting rod 24 is hinged to the second pressing block 23, a pressing portion 231 is arranged at one end of the second pressing block 23, and the other end of the second pressing block is hinged to the second oil cylinder 25. During the use, drive second briquetting 23 through second hydro-cylinder 25 and rotate around the one end of connecting rod 24, the other end of connecting rod 24 rotates around second mount pad 22 simultaneously, until the open mode (second briquetting 23 is vertical state), and then do not influence the valve plate and put into the anchor clamps.

In one embodiment, as shown in FIGS. 1-6, a blow tube 26 is provided on one side of the bottom support block 21. Because of the cutter during drilling, can produce iron fillings, and when taking out the valve plate that the processing was accomplished, iron fillings can fall on bottom supporting shoe 21, and when putting new valve plate on the top, this iron fillings can make the valve plate bed high, causes the drilling position cheap for the valve plate is scrapped. By blowing through the blowing pipe 26 before a new valve plate is placed each time, it can be effectively ensured that scrap iron does not remain on the bottom support block 21.

In one embodiment, as shown in fig. 1 to 5, the valve further includes a thick positioning column 6, and the thick positioning column 6 is located at the periphery of the valve plate and is fixedly installed on the bottom plate 1. Specifically, thick reference column 6 sets up threely, and first side department sets up two, and second side department sets up one, and it is regional to inject the great placing than the valve plate through thick reference column 6 and side supporting block 3, then adjusts valve plate position through side hold-down mechanism. Thereby the valve plate is more convenient to position.

In one embodiment, as shown in fig. 1-5, the bottom plate 1 is further provided with a support cylinder 7 and is located at the bottom of the valve plate. The valve plate is carried by the support cylinder 7 to improve the stability of the clamp for clamping the valve plate.

In one embodiment, as shown in fig. 1-5, the side support block 3 is located at an extended position where the first side hold-down mechanism 4 acts on the valve plate in the hold-down direction.
