Abstract
The present invention relates to a pneumatic fixture for processing workpieces in uncommon shapes, which is characterized in that the fixture mainly consists of a disc type right-angle bent plate, a workpiece mounting seat, a fastening mechanism and a pneumatic device; taper threads fitting with the main shaft of a lathe are arranged in the center of the disc type right angle bent plate, and the workpiece mounting seat is fixed on the bent plate plane which is perpendicular to the surface of the disk; the workpiece mounting seat mainly consists of a V-shaped seat, a work bench and a sleeve, the V-shaped seat is fixedly connected with the work bench, the round shaft of the work bench is connected with the sleeve by a bearing, and the sleeve is fixedly connected with a central hole on the bent plate plane which is perpendicular to the surface of the disk. Workpieces in uncommon shapes can be directly turned by being clamped by the fixture. The fixture is particularly suitable for processing the seal surface angles of gate valve seats. The fixture is arranged on the main shaft of the lathe. After workpieces are installed and clamped in one step, the seal surfaces of the gate valve seats are processed into an angle of 6 degrees to 8 degrees under the guarantee of a workpiece locating table. The present invention has the advantages of convenient installation and clamp, simple processing and high production efficiency largely improved.
Description
Technical field
The invention belongs to turning attachment, relate in particular to a kind of Pneumatic fixture for processing workpieces in uncommon shapes.
Background technology
The machined into special-shaped workpiece adopts on the floral disc fixedly angle block of right angle usually, special-shaped workpiece is fixed on the bent plate with pressing plate again, uses the tosecan alignment, processes behind the fastening workpiece.Waste time and energy, the incompatible demand of producing in enormous quantities is especially produced the unit of valve, and it is very big to produce quantity on order, requires to adopt special fixture to process just and can finish the work.Valve valve seat inner sealing surface and valve body center line have 68 ° angle to be commonly called as " the valve seat pendulum tip ", add originally to adopt man-hour during the said method single-piece is installed, looks for, and two sealing surface angles machine at twice, and labor productivity is extremely low.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned technology, and a kind of Pneumatic fixture for processing workpieces in uncommon shapes is provided, be installed on the lathe spindle, after workpiece once is installed, make valve seat and lathe bed axis keep 90 °, 6-8 ° the angle of processing the gate valve valve seat.
The present invention for achieving the above object, by the following technical solutions: a kind of Pneumatic fixture for processing workpieces in uncommon shapes, it is characterized in that: mainly by the disc type angle block of right angle, the workpiece mount pad, clamp mechanism and pneumatic means constitute, described disc type angle block of right angle center is provided with the taper thread that cooperates with lathe spindle, fixation workpiece mount pad on the bent plate plane of vertical disc surfaces, described workpiece mount pad is mainly by V-shape base, workbench and sleeve constitute, described V-shape base and workbench are affixed, the circular shaft of described workbench is connected with sleeve by bearing, and sleeve is affixed with the centre bore on the bent plate plane of vertical disc surfaces.
Described clamp mechanism mainly is made of support, pressure head, hook-shaped pressing plate, described support is fixed on the disc surfaces of disc type angle block of right angle, be axially arranged with elongated slot on the support, middle and the support pin joint of described hook-shaped pressing plate, hook-shaped pressing plate front end places elongated slot and touches with pressure head, hook-shaped pressing back-end is connected with the cylinder piston rod of pneumatic means, and the centre bore of described pressure head and support is slidingly connected.
The bent plate plane of described vertical disc surfaces is provided with the workpiece positioning table, and described workpiece positioning table is adjusted the angle of workpiece mount pad by adjusting screw.
Beneficial effect of the present invention: can on lathe, carry out turning processing by the clamping special-shaped workpiece.Especially at the processing of gate valve sealing surface of seat angle.Anchor clamps are installed on the lathe spindle, workpiece once is installed after, can guarantee that by the workpiece positioning table sealing surface after the gate valve valve seat processing is 6-8 ° a angle.Be installed convenience, processing simply, improved production efficiency greatly.
Description of drawings

Fig. 2 is the right view of Fig. 1.
The specific embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing and preferred embodiment.
See accompanying drawing for details, a kind of Pneumatic fixture for processing workpieces in uncommon shapes, mainly by disc type angle block of right angle 1, workpiece mount pad 2, clamp mechanism 3 and pneumatic means 4 constitute, described disc type angle block of right angle center is provided with the taper thread (not shown) that cooperates with lathe spindle 5, fixation workpiece mount pad on the bent plate plane of vertical disc surfaces, described workpiece mount pad is mainly by V-shape base 2-1, workbench 2-2 and sleeve 2-3 constitute, described V-shape base and workbench are affixed, the circular shaft of described workbench is connected with sleeve by bearing 2-4, and sleeve is affixed with the centre bore 1-1 on the bent plate plane of vertical disc surfaces.Described clamp mechanism mainly is made of support 3-1, pressure head 3-2, hook-shaped pressing plate 3-3, described support is fixed on the disc surfaces of disc type angle block of right angle, be axially arranged with elongated slot 3-4 on the support, middle and the support pin joint of described hook-shaped pressing plate, hook-shaped pressing plate front end places elongated slot and touches with pressure head, hook-shaped pressing back-end is connected with the cylinder piston rod 4-1 of pneumatic means, and the centre bore 3-5 of described pressure head and support is slidingly connected.The bent plate plane of described vertical disc surfaces is provided with workpiece positioning table 6, and described workpiece positioning table is adjusted the angle of workpiece 8 mount pads by adjusting screw 7, is 6-8 ° angle with the sealing surface after the processing of assurance gate valve valve seat.
During work, the workman puts into brake valve body on the V-shape base of workpiece mount pad, pulls the control valve of pneumatic means, and piston rod moves, and spurs hook-shaped pressing plate front end and moves down, and makes pressure head push down workpiece.Should adjust the position between workpiece mount pad and the workpiece positioning table before the processing earlier, to guarantee the angle after the gate valve sealing surface of seat is processed.
The above only is preferred embodiment of the present invention, is not structure of the present invention is done any pro forma restriction.Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
