Abstract

The utility model discloses a machining device for a valve plate of a butterfly valve, which comprises a machine frame. The top surface of the machine frame is provided with a sliding supporting plate, and the top surface of the sliding supporting plate is provided with a fixture for fixing the valve plate. Two sides of the sliding supporting plate are provided with a first drill, a second drill, a first milling cutter and a second milling cutter, wherein the first drill and the second drill are corresponding to each other in positions, and the first milling cutter and the second milling cutter are corresponding to each other in positions. The first drill, the second drill, the first milling cutter and the second milling cutter are respectively provided with a driving mechanism. The machining device for the valve plate of the butterfly valve utilizes the two drills and the two milling cutters to perform hole machining at two ends of the valve plate and enable the end face of the valve plate to be flat by milling, thereby improving machining efficiency of the valve plate.

Description

A kind of processing unit (plant) of butterfly valve plate

Technical field

The utility model relates to a kind of metal-working plant, relates in particular to a kind of equipment that is used to process butterfly valve plate end holes and end face.

Background technology

The valve plate of butterfly valve has radial direction through hole, is used to pass valve rod, referring to Fig. 1; (some situation is that the hole forms in valve plate casting to portal 3 in the processing of the two ends of valve plate 1 in processing during valve plate 1; But need process the inwall in hole, make that it is smooth), the end face 2 in hole 3 need be processed into the plane.

The processing of prior art mesopore 3 and end face 2 need utilize two equipment, and valve plate need transmit at two equipment rooms, has reduced operating efficiency.

The utility model content

The utility model provides a kind of easy to use, processing unit (plant) that efficient is high, can utilize a table apparatus to process the hole and the end face at valve plate two ends respectively.

A kind of processing unit (plant) of butterfly valve plate; Comprise frame; Described frame end face is provided with slip blade, and the slip blade end face is provided with the anchor clamps that are used for fixing valve plate, and the both sides of slip blade are provided with corresponding first drill bit in position and second drill bit; And corresponding first milling cutter in position and second milling cutter, described first drill bit, second drill bit, first milling cutter and second milling cutter are respectively equipped with driving mechanism.

After valve plate is fixed on the slip blade end face; Utilize first drill bit and second drill bit of both sides to portal in the processing of valve plate two ends; Through moving of slip blade, can drive valve plate and be between first milling cutter and second milling cutter, utilize first milling cutter and second milling cutter to process the valve plate end faces of both sides.

Described first drill bit and first milling cutter are arranged along the direction of motion of slip blade.

Described anchor clamps constitute by first chuck that is fixed on the slip blade end face with second chuck that the slip blade end face is slidingly matched.Second chuck can be movable; Be convenient to pick and place the valve plate of generation processing, second chuck and slip blade end face can cooperatively interact through guide rail and the guiding parts that cooperates with guide rail, realize the activity of second chuck; For the ease of the location of second chuck, can be provided with bolt or other positioning element.

Described first chuck and the second chuck opposed edges match with the outer rim shape of valve plate, clamping valve plate that can be fastening.

The processing unit (plant) of the utility model butterfly valve plate utilizes two drill bits and two milling cutters to portal and facing cut is flat in the processing of valve plate two ends, has improved the working (machining) efficiency of valve plate.

Description of drawings

Fig. 1 is the structural representation of valve plate to be processed;

Fig. 2 is the structural representation of the utility model processing unit (plant);

Structural representation when Fig. 3 processes the valve plate end face for the utility model processing unit (plant).

The specific embodiment

Referring to Fig. 2,3; The processing unit (plant) of a kind of butterfly valve plate of the utility model; Comprise frame (omitting among the figure); The slip blade 5 that the frame end face is provided with guide rail 4 and is slidingly matched with guide rail 4, the slip blade end face is provided with the anchor clamps that are used for fixing valve plate, and anchor clamps constitute by first chuck 8 that is fixed on slip blade 5 end faces with second chuck 9 that slip blade 5 end faces are slidingly matched.First chuck 8 and second chuck, 9 opposed edges match clamping valve plate that can be fastening with the outer rim shape of valve plate 1.

The both sides of slip blade 5 are provided with corresponding first drill bit 7 in position and second drill bit, and corresponding first milling cutter 6 in position and second milling cutter, and all drill bits and milling cutter utilize prior art to be connected to driving mechanism.Drill bit and milling cutter arrange along the direction of motion of slip blade 5, for valve plate is processed, the drill bit that is provided with in pairs and milling cutter self rotary while can also do mutual near or away from motion.

Valve plate 1 is fixed on slip blade 5 end faces during use; First drill bit 7 and second drill bit that utilizes both sides at valve plate 1 two ends processing portal; Slip blade 5 drives valve plate 1 motion then; Valve plate 1 is between first milling cutter 6 and second milling cutter, utilizes first milling cutter 6 and second milling cutter that valve plate 1 end faces of both sides is processed into the plane.
