The utility model discloses a double tops point effort, anchor clamps expand in double tops struts, and the once required precision of dress card realization axiality has been guaranteed on being used in the hole reference surface of work piece to the masterpiece, has solved artifical timing work piece concentricity problem, and this anchor clamps expand in double tops does not need straight mouthful of machining center frame yet.

Description

Swollen fixture in Double Tops
Technical field
This utility model relates to a kind of cylindrical parts workpiece clamping tool for machine work, swollen fixture in specifically a kind of Double Tops.
Background technology
Cylinder barrel class workpiece clamping tool for machine work is a kind of special equipment for cylinder barrel class workpiece.Affected by factors such as process conditions, equipment precision and location modes, current China is this kind of not only met craft precision requirement but also do not destroyed the frock clamp on other surface of workpiece the most immature.
The processing request of cylinder barrel class workpiece is higher, and the particularly this kind of workpiece having concentricity and axiality to require of hydraulic oil cylinder barrel is more difficult to ensure.At present, the cylinder mouth processing of domestic hydraulic cylinder class is installed and cylinder center's rack-mounted card two ways with centre frame the most again.Centre frame clamping complex procedures, by feeling relieved with endoporus, the straight mouth of processing central bracket, again centre frame is fixed on straight mouth, workpiece secondary will produce error, concentricity, linearity is the most impacted, when workpiece rotates, the abrasion of centre frame abrasion and frame position also can affect the precision of workpiece, the complex art of workman is required the highest by work progress, although emerge now with hydraulic center frame and double main axle machine tool, its price and costliness thereof, small enterprise is expected to ask, thus production cost is also substantially improved, it addition, a lot of workpiece does not allow the straight mouth of processing central bracket;Cylinder center's frame is a kind of fixture being widely used in recent years, it is adjusted bolt by bearing block and four and forms, bearing block is fixed on machine tool track, by adjusting the degree of tightness of four screws, reach the concentricity of workpiece displacement adjustment workpiece, the power of machine tool chief axis passes to workpiece, realizes rotating processing by the bearing on bearing block.This fixture equally exists problems with: 1, the elasticity of four bolts is inconsistent, can produce workpiece circumference unbalance stress, and it is oval that workpiece takes off post-treatment face.2, bearing clearance is very big to crudy image, makes the precision of workpiece, roughness be extremely difficult to requirement.3, requiring the highest to the technical quality of workman, labor intensity during workman's adjustment workpiece is the biggest.
Summary of the invention
The problem existed for above-mentioned prior art, this utility model provides swollen fixture in a kind of Double Tops, in these Double Tops, swollen fixture not only solves processing central bracket straight mouth problem, also solve artificial adjustment concentricity of workpiece problem, workpiece circumference uniform force, ensure that once is installed realizes the required precision of axiality, improves precision, roughness.
To achieve these goals, the technical solution adopted in the utility model is: swollen fixture in a kind of Double Tops, including actively holding out against head and expansion core assembly, the described head that actively holds out against is the front end cylinder with conehead;Described expansion core assembly is held out against swollen dish by a left side, the right side holds out against swollen dish and connecting rod assembly is integral, a left side holds out against swollen dish and the right side holds out against swollen disk center and has big mouth outward taper hole, tapered hole is coaxial with cylindrical outer wall, a left side holds out against swollen dish and holds out against swollen dish end face along center to external radiation disconnection with the right side, disconnect the degree of depth to connecting rod, a left side holds out against swollen dish and passes through actively to hold out against the tight distending in the crown, and the right side holds out against swollen dish and held out against distending by the live center installed on tailstock tool.
Further, a left side holds out against swollen dish and holds out against swollen dish end face along center to the indexing disconnection of the external radiation quartering with the right side.
Further, actively holding out against head is stainless steel.
This utility model is held out against the tapered hole at center, swollen dish one end and is felt relieved by the active expansion head being arranged on lathe spindle;The swollen dish that holds out against of the other end is held out against by the live center of tailstock tool, pressure forces and holds out against swollen dish distending, expansive force acts in workpiece inner wall, workpiece obtains the concentricity equal with machine tool accuracy and axiality and enough tension forces by actively expansion head and rolling center, lathe tool carries out machining, by Double Tops point active force, in Double Tops, swollen fixture struts, power acts on the internal hole reference face of workpiece, ensure that once is installed realizes the required precision of axiality, solving artificial adjustment concentricity of workpiece problem, in these Double Tops, swollen fixture is also without the straight mouth of processing central bracket.
Accompanying drawing explanation
Fig. 1 is utility model works schematic diagram;
Fig. 2 is expansion core assemble cross-section;
Fig. 3 is expansion core component left view.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, swollen fixture in this utility model Double Tops, including actively holding out against 2 and expansion core assembly, it is the front end cylinder with conehead that described active holds out against 2;Described expansion core assembly is held out against swollen dish 6 by a left side, the right side holds out against swollen dish 8 and connecting rod 7 is combined into one, a left side holds out against swollen dish 6 and the right side holds out against swollen dish 8 center and has big mouth outward taper hole, tapered hole is coaxial with cylindrical outer wall, a left side holds out against swollen dish 6 and holds out against swollen dish 8 end face along center to external radiation disconnection with the right side, disconnect the degree of depth to connecting rod 7, a left side holds out against swollen dish 6 and holds out against distending by actively holding out against 2, and the right side holds out against swollen dish 8 and held out against distending by the live center 9 installed on tailstock tool.
As shown in Figures 2 and 3, a left side holds out against swollen dish 6 and holds out against swollen dish 8 end face along center to the indexing disconnection of the external radiation quartering with the right side.Hold out against swollen dish end face to disconnect along center to external radiation, be in order to hold out against swollen dish can distending smoothly, 2 equal portions, 3 equal portions, 4 equal portions etc. can be divided into, decile distending very little has some setbacks, the too many contact area of decile very few and make inconvenient.
Actively holding out against head is stainless steel.
In Double Tops during the work of swollen fixture, installing active and hold out against 2 on machine tool chief axis or scroll chuck 1, actively holding out against the front end of 2 has and holds out against, with left, the tapering that the swollen supercentral taper hole of dish 6 fits like a glove.Actively hold out against 2 power and the axiality of main shaft are delivered to a left side and are held out against on swollen dish 6.In Double Tops, the other end right side of swollen fixture holds out against swollen dish 8 and is held out against by the live center 9 of tailstock tool.Under the power effect of top, top on tapering force a left side to hold out against swollen dish 6 to hold out against swollen dish 8 distending with the right side, expansive force acts on the inwall of workpiece 5, it is achieved clamping force, and workpiece clips, and cylindrical chamfering tool 3, cutter 4, inner circle chamfering tool 10 carry out machining.
