Background technology
In Die Casting Workshop, usually need the pad using ring-type, tightr to realize combining between two parts, and annular shim in use, in order to meet and the laminating of different part, also usually need annular shim for further processing, as the processing of counterbore or deburring etc.At present, further added man-hour to annular shim, normally pad directly presses on workbench with hand by operating personnel, cutter is used to process pad by other operating personnel again, because cutter can produce vibration usually when operation, described vibration can cause the hand pressing pad to produce shake, and the shake of hand can cause pad to be subjected to displacement, thus makes the mismachining tolerance of pad large; In addition, by the hand pressing pad of operating personnel, during cutter operation, easy opponent damages, operational hazards.
Utility model content
The technical problems to be solved in the utility model is technological deficiency that is large for current processing annular shim time error, operational hazards, provides a kind of and clamps that processing annular shim time error is little, the loop pads blade clamping device of handling safety.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: annular shim clamping device, comprises machine table and mandrel, and machine table upper end is provided with blind hole, is provided with internal thread in blind hole; Mandrel comprises large journal axle and little journal axle, and large journal axle is provided with external screw thread, the external screw thread of large journal axle and the screw-internal thread fit of blind hole; Also comprise pneumatic shuttle, described pneumatic shuttle comprises pressure column and circular briquetting, pressure column is sheathed in little journal axle, pressure column is provided with gas passage, one end of gas passage is provided with plunger, it is upper in the below place of pressure column that described briquetting is sheathed on little journal axle, and briquetting and little journal axle are slidably connected, the upper surface of briquetting is provided with projection, protruding end is provided with piston, and the end of projection is positioned at gas passage one end away from plunger, the distance between protruding apex and briquetting bottom is greater than the distance between pressure column bottom and large journal axle top.
Adopt the annular shim clamping device of technical solutions of the utility model, comprise machine table, machine table is used for positioning mandrel, and machine table can from the below of workpiece by workpiece pre-tightening, also comprise mandrel, mandrel comprises large journal axle and little journal axle, the blind threaded cooperation in large warp beam and machine table, thus realizes the location of axle, also comprise pneumatic shuttle, annular work piece is compressed by the upper end of gas pressure from annular work piece by pneumatic shuttle, thus realize locating the compression of workpiece, pneumatic shuttle comprises pressure column and circular briquetting, pressure column is cylindric, pressure column is fixedly connected with little journal axle, pressure column is provided with gas passage, gas is filled with in gas passage, one end of gas passage is provided with plunger, plunger can move in gas passage, when plunger moves inward, gas in gas passage is compressed, thus the gas pressure increased in gas passage, it is upper in the below place of pressure column that briquetting is sheathed on little journal axle, workpiece to be sheathed on mandrel between briquetting and machine table, briquetting compresses from the upper surface of workpiece workpiece, briquetting and little journal axle are slidably connected, thus briquetting can do axial slip along little journal axle under external force, the upper surface of briquetting is provided with projection, protruding end is provided with piston, and the end of projection is positioned at gas passage, thus piston coordinates plunger to form closed airtight space in gas passage, when piston moves inward, gas pressure in gas passage increases, thus piston is subject to a downward pressure, according to the transfer principle of power, briquetting also gives annular shim one below briquetting downward pressure, thus annular shim is pressed in machine table, to facilitate, annular shim is processed, distance between protruding apex and briquetting bottom is greater than the distance between pressure column bottom and large journal axle top, thus the briquetting when mandrel being taken out blind hole can be avoided to be promoted outward by the pressure in gas passage and cause briquetting and mandrel to depart from.Can ensure that annular shim is clamped owing to adopting during the utility model clamping annular shim without the need to pressing with hand, avoid the operational hazards caused with hand pressing annular shim, and machine table is fixed on lathe, avoiding in processing operation process causes pad to be subjected to displacement because of the vibration of cutter, and error is little.
Further, described gas passage comprises screw channel and smooth passage away from one end of projection, and screw channel is positioned at the outside of smooth passage, and plunger is positioned at smooth passage, is provided with adjusting screw(rod) in screw channel, and adjusting screw(rod) and plunger offset.Threaded rod moves to inside spin, can promote plunger and move inward, and the threaded engagement of threaded rod and screw channel can be carried out spacing by double thread bar, thus can fill in capable spacing by coupled columns.
Further, the quantity of described gas passage and protruding quantity are two, and two gas passages and two projections are positioned at the both sides of mandrel respectively, and two protruding ends lay respectively in two gas passages.Two gas passages and two projections that lay respectively at mandrel both sides can make annular shim stress balance.
Further, described pressure column is also provided with two air-filled pores, two air-filled pores communicate with two gas passages respectively.Air-filled pore to insufflation gas in gas passage, can increase the gas pressure in gas passage.
