Description
TECHNICAL FIELD
[0001] The utility model belongs to processing equipment field, concretely relates to the processing equipment of butterfly valve butterfly plate. BACKGROUND
[0002] The butterfly valve is a kind of valve, and the disc is the opening and closing part, which rotates 90° around the axis to achieve opening and closing. The butterfly valve is mainly composed of valve body, butterfly plate, valve seat, valve stem and drive, and the drive is connected with the valve body. The drive rotates to drive the valve stem to rotate, and the valve stem rotates to drive the butterfly plate to rotate. The opening and closing of the valve are realized by the rotation of the butterfly plate.
[0003] The butterfly plate is an important part of the butterfly valve, and its machining precision is directly related to the service life and opening and closing torque of the butterfly valve. In the traditional machining method, the outer circle of the butterfly plate is first machined by the first lathe, and then the outer circle after machining is used for positioning. The one end of the shaft hole of the butterfly plate is machined by the second lathe. Finally, the outer circle and the shaft hole after machining are used for positioning, and the other end of the shaft hole of the butterfly plate is machined by the third lathe. Since the butterfly plate is clamped multiple times in this method, cumulative positioning error is generated, which causes unstable processing of the symmetry of the outer circle and the shaft hole of the butterfly plate, and seriously affects the service life and opening and closing torque of the butterfly valve. CONTENT OF THE UTILITY MODEL
[0004] The utility model aims at providing a butterfly valve butterfly plate processing equipment which is convenient and fast to clamp, has high machining efficiency, good quality and low cost. The machining of butterfly plates of various sizes can be completed by simply replacing the clamp.
[0005] The utility model takes the technical scheme: a device for completing the machining of butterfly valve butterfly plate in one clamping, comprising: bed body, X-axis linear guide rail servo sliding table, servo spindle power head workbench, Y-axis linear guide rail servo sliding table, six-station servo rotary power cutter tower, Z-axis linear guide rail servo sliding table and numerical control system, the bed body is cross-shaped, the X-axis linear guide rail servo sliding table is fixed in the vertical direction of the bed body, the servo spindle power head workbench is installed on the X-axis linear guide rail servo sliding table, the servo spindle power head workbench is composed of X-axis sliding table workbench, servo spindle power head, clamp, butterfly plate and pressing cylinder, the servo spindle power head and the pressing cylinder are fixed on the X-axis sliding table workbench by bolts, and the clamp is arranged between the servo spindle power head and the pressing cylinder, the Y-axis linear guide rail servo sliding table and the Z-axis linear guide rail servo sliding table are fixed in the horizontal direction of the bed body, the six-station servo rotary power cutter tower is respectively installed on the Y-axis linear guide rail servo sliding table and the Z-axis linear guide rail servo sliding table, and the numerical control system is connected with the above-mentioned electrical components.
[0006] The working principle of the device is that: the butterfly plate is installed on the servo spindle power head workbench through the special clamp and clamping cylinder, the butterfly plate is rotated by the servo spindle power head, the Y-axis side six-station servo rotary power tool turret No. 1 is used to process the outer circle of the butterfly plate, after the outer circle processing is completed, the butterfly plate shaft hole is rotated to the parallel position with the Y and Z axis movement directions by the servo spindle motor, the spindle stops rotating and is fixed in direction, the six-station servo rotary power tool turret on the two sides of the Y and Z axes processes the butterfly plate shaft hole through No. 2 end face milling cutter, No. 3 rough boring hole cutter, No. 4 precise boring hole cutter and No. 5 inner hole chamfer cutter, and the butterfly plate is processed on both sides at the same time.
[0007] Compared with the prior art, the device has the advantages that: product quality: since the processing of the butterfly plate is completed by one-time clamping, the unstable processing precision of the butterfly plate caused by positioning error is avoided, and the six-station servo power tool turret has sufficient cutter position, can process the butterfly plate shaft hole by rough and precise boring multiple times, and has stable shaft hole diameter size and high position precision.
[0008] Production efficiency: the processing of the butterfly plate is completed by one-time clamping, the clamping time is reduced, the six-station rotary servo power head slide table on both sides can process at the same time, the processing time can be reduced by half, the pneumatic pressing is convenient and fast, the part mounting and dismounting time is reduced, and the labor intensity of the operator is reduced.
