Realize above-mentioned technical purpose; The axle of the utility model type part anchor clamps; Comprise top, edge of a knife seat, be fixedly connected on the terminal pad of said edge of a knife seat bottom, be provided with the spring installation cavity and the superposed top installation cavity that are positioned at the bottom in the said edge of a knife seat, said tail spindle is in being assemblied in said top installation cavity movably; And top length is greater than the length of said top installation cavity; And, being provided with spring in the said spring installation cavity less than the length sum of said top installation cavity and spring installation cavity, said both ends of the spring is resisted against respectively between said top bottom and the terminal pad.
Further, said top bottom is provided with loop bar, and said spring housing is contained on the said loop bar;
Further, the top end face of said edge of a knife seat is provided with at least two edges of a knife that are uniformly distributed with setting ringwise;
Further, the said edge of a knife is strip, and the bearing of trend of the said edge of a knife is positioned at said top installation cavity in the radial direction;
Further, said edge of a knife cross section is trapezoidal, and the wide 0.1-0.2mm in the top of the edge of a knife.
The beneficial effect of the utility model is:
1, the terminal pad of the axle of the utility model type part anchor clamps is installed on the lathe; The top centre bore that places on the workpiece; Through the positioning and clamping between top and the centre bore, can effectively improve the clamping precision of shaft-like workpiece, and need on workpiece, just can not realize clamping by prefabricated sufficiently long retaining part; Simple and convenient, operation easy to implement; Top length is set to the length greater than top installation cavity; And less than the length sum of top installation cavity and spring installation cavity; Make top at action of hydraulic force lower compression spring; Make the upper surface and the workpiece end face of edge of a knife seat fit tightly,, make workpiece can bear certain moment of torsion through the frictional force between workpiece and the edge of a knife seat; Therefore, the axle of the utility model type part anchor clamps are clamping work pieces effectively, and the clamping workpiece precision is high, and clamping process is easy, even do not have also can realize clamping under the situation of enough retaining parts at workpiece;
2, through on edge of a knife seat upper surface, the edge of a knife being set, workpiece under action of hydraulic force, the compression spring, the edge of a knife is embedded in the workpiece end face, makes that workpiece can transfer larger torque, is convenient to the machined of workpiece.

The specific embodiment
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the utility model.
As shown in Figure 2, be the structural representation of the utility model axle class part anchor clamps embodiment.The axle of present embodiment type part anchor clamps; Comprise top 1, edge of a knife seat 2, be fixedly mounted on the terminal pad 3 of said edge of a knife seat 2 bottoms through bolt 9; Be provided with the spring installation cavity 4 and superposed top installation cavity 5 that are positioned at the bottom in the said edge of a knife seat 2; Said top 1 is assemblied in the said top installation cavity 5 with moving axially, and top 1 length is greater than the length of said top installation cavity 5, and less than the length sum of said top installation cavity 5 and spring installation cavity 4; Be provided with spring 6 in the said spring installation cavity 4, said spring 6 two ends are resisted against respectively between said top 1 bottom and the terminal pad 3.Preferably, said top 1 bottom is provided with loop bar, and said spring 6 is sleeved on the said loop bar, is convenient to spring 6 elongations and compression.
The terminal pad 3 of the axle of present embodiment type part anchor clamps is installed on the lathe; Top 1 places the centre bore on the workpiece 7; Through top 1 and centre bore between positioning and clamping, can effectively improve the clamping precision of shaft-like workpiece 7, and need on workpiece, just can not realize clamping by prefabricated sufficiently long retaining part; Simple and convenient, operation easy to implement.Top 1 length is set to the length greater than top installation cavity 5; And less than the length sum of top installation cavity 5 and spring installation cavity 4; Make top 1 at action of hydraulic force lower compression spring 6; Make the upper surface and workpiece 7 end faces of edge of a knife seat 2 fit tightly,, make workpiece 7 can bear certain moment of torsion through the frictional force between workpiece 7 and the edge of a knife seat 2.
Therefore, it is not enough that the axle type part anchor clamps of the utility model efficiently solve workpiece 7 clamping lengths, need do the technology lengthening and increase the problem that the cost of operation increases, and not cost power during clamping, only needs the workman before last top depressing, to set upright and get final product; Because adopt Double Tops point location, the benchmark during with detection is consistent, positioning accuracy is high, and tooth runout can guarantee in 0.012mm in batches; The versatility of these class part anchor clamps is good, need not do special jaw, the applicable diameter of axle in a big way, and can be used for the operation such as turning and Milling Process of axial workpiece.
Further, the top end face of said edge of a knife seat 2 is provided with at least two edges of a knife 8 that are uniformly distributed with setting ringwise, through the edge of a knife 8 is set; Workpiece 7 is under action of hydraulic force; Compression spring 6, the edge of a knife 8 is embedded in workpiece 7 end faces, makes that workpiece can transfer larger torque; Be convenient to the machined of workpiece, edge of a knife seat 2 upper surfaces of present embodiment are provided with the edge of a knife 8 that 6 annulars are uniformly distributed with.Preferably, the said edge of a knife 8 is strip, and the bearing of trend of the said edge of a knife 8 is positioned at said top installation cavity 5 in the radial direction, can strengthen the stress performance of the edge of a knife, makes the edge of a knife 8 can bear bigger cutting force.Preferably, the said edge of a knife 8 cross sections are trapezoidal, and the wide L=0.1-0.2mm in the top of the edge of a knife 8, make the edge of a knife 8 under action of hydraulic force, can be embedded into smoothly in the workpiece 7, make and can bear bigger moment of torsion between the workpiece 7 and the edge of a knife 8.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the aim and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
