Abstract
The utility model relates to a high-efficiency fixture for processing valve bodies, which comprises a bottom plate, an upper pressure plate, V-shaped blocks, positioning pins and bolts; wherein, three V-shaped blocks are arranged on the bottom plate which is fixed on a working table for a machine tool through the positioning pins and T-shaped bolts; taking three end face encircles of a workpiece valve body as the positioning reference, the workpiece valve body is arranged on the three V-shaped blocks; the upper pressure plate is connected with the bottom plate by four bolts; and a kidney-shaped hole capable of rapidly assembly and disassembly is arranged on the upper pressure plate. The high-efficiency fixture is applied to the processing of the valve bodies on a four-axle machining center or a three-axle machining center which is additionally provided with a rotating working table; the requirements for verticality and position accuracy are easily guaranteed, and at the same time, the high-efficiency fixture can be rapidly assembled and disassembled and the machining accuracy of workpieces can be guaranteed. The utility model has the advantages that the fixture can improve production efficiency, is convenient to operate, shortens the auxiliary time, improves the working efficiency by 5 to 8 times, has good economical efficiency and simple structure, is easy to manufacture and reduces the manufacture cost as well as the labor intensity of workers.
Description
Technical field
The utility model relates to a kind of High efficient clamp of processing valve body.
Background technology
At present, China's a large amount of production of copper valve outlets in some area are earned foreign exchange, and domestic military project and civilian demand are also very big simultaneously, and market form is fine, and supply falls short of demand.In traditional processing technology, mainly adopt processing such as plain-milling machine, boring machine, lathe and drilling machine, guarantee that the position degree must lean on artificial smart centering.There are a lot of defectives in this processing mode:
(1) manufacturing procedure is long, and nearly 20 procedures are wanted in the valve body processing that has, and production efficiency is low.
(2) by traditional handicraft---very high by artificial smart centering to workman's technical merit requirement, unstable product quality.
(3) for the high accuracy high value-added product, it is qualified to be difficult to processing.As: the perpendicularity in the φ E of certain water under high pressure valve body (as Fig. 1) and two holes of φ C is 0.03, and the position degree is φ 0.01, requires all very highly, and traditional handicraft be difficult to guarantee machining accuracy.
(4) be unfavorable for quality control, be unfavorable for the modern production management.
Summary of the invention
The utility model is to overcome above defective and provide a kind of and be applied to four machining centers or three machining centers and need install valve body processing on the rotary table additional, than being easier to guarantee perpendicularity and position degree requirement, a kind of High efficient clamp of processing valve body that can load and unload fast simultaneously.
The technical scheme that the utility model provides for achieving the above object comprises, these anchor clamps comprise base plate, top board, vee-block, alignment pin and bolt, wherein three vee-blocks are installed on the base plate, base plate is fixed on the workbench of lathe by alignment pin and tommyhead bolt again, processing work " valve body " serves as the location benchmark with three end face cylindricals, be installed on three vee-blocks, top board is connected on the base plate with four bolts, have on the top board and can install and remove kidney shape hole fast, after being placed on valve body on the vee-block, can load onto pressing plate fast, but screw just workpiece pressing of bolt, can begin processing.
Advantage of the present utility model is,
(1) machining accuracy of assurance workpiece;
(2) enhance productivity, easy to operate, shorten non-cutting time, improve 5～8 times of work efficiency;
(3) adopt the vee-block location good, the location datum axis of valve body is centered on the symmetrical plane on vee-block amount inclined-plane neutrality, and easy for installation;
(4) processing performance is good, anchor clamps simple and reasonable for structure, assembling, adjustment, check, maintenance etc.;
(5) serviceability is good, and the operation of anchor clamps should be easy, laborsaving, safe and reliable;
(6) good economy performance, simple in structure, easy to manufacture, to reduce the manufacturing cost of anchor clamps;
(7) alleviated working strength of workers.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is base plate, vee-block and the alignment pin scheme of installation of anchor clamps among Fig. 1.
The specific embodiment
Embodiment, as depicted in figs. 1 and 2, these anchor clamps comprise base plate 1, top board 5, vee-block 3,4,8, alignment pin 2, M14 bolt 6 and M18 bolt 7 compositions.
Three vee-blocks 3,4,8 are installed on the base plate 1, and base plate 1 is fixed on the workbench of lathe by alignment pin 2 and tommyhead bolt again.Processing work " valve body " 9 serves as the location benchmark with three end face cylindricals, is installed on three vee-blocks.Top board 5 is connected on the base plate 1 with four M14 bolts 6, has on the top board 5 to install and remove kidney shape hole fast, be placed on valve body on the vee-block after, can load onto pressing plate 5 fast, but screw just workpiece pressing of M18 bolt 7, can begin processing.
Claims (1)
1, a kind of High efficient clamp of processing valve body, it is characterized in that, comprise base plate (1), top board (5), vee-block (3,4,8), alignment pin (2) and bolt composition, wherein three vee-blocks (3,4,8) are installed on the base plate (1), base plate (1) is fixed on the workbench of lathe by alignment pin (2) and tommyhead bolt again, processing work " valve body " (9) serves as the location benchmark with three end face cylindricals, be installed on three vee-blocks, top board (5) is connected on the base plate (1) with four bolts (6), and top board (5) is provided with the kidney shape hole that can install and remove fast.
