The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.

As shown in Figure 1, in the present embodiment,

part

10,20 to be press-fited is annular, and wherein part 10 need to be press-fitted in part 20 hole 21; In addition, part 10 centers also offer porose 11.After

part

10,20 press-fits, the structure of the

part

10,20 having press-fited as shown in Figure 2.

Referring to Fig. 3, pressing clamp described in the utility model comprises clamp body 100, axle 200 and the alignment pin 300 being arranged on base 50, and above-mentioned part to be press-fited 10,20 is placed in this axle 200, wherein:

Clamp body 100 is the tubular interface of a hollow, and clamp body 100 bottoms fix by bolt 51 and base 50, and clamp body 100 is coaxial with base 50; Axle 200, alignment pin 300 and spring 70 are all placed in this clamp body 100, and axle 200 coaxially arranges with clamp body 100, and with the inwall matched in clearance of clamp body 100, axle 200 can freely move up and down along clamp body inwall; Wherein, axle 200 tops exceed clamp body 100 under off working state, in working order next being depressed in clamp body 100.

Axle 200 and the concentric setting of clamp body 100, axle 200 top surfaces have annular protrusion 210, and part 10 to be press-fited is positioned on this annular protrusion 210, and mutually aligns with this axle 200 by alignment pin 300.

Axle 200 centers have hole 202, and above-mentioned alignment pin 300 bottom is arranged on this Kong202Nei， top and from the upper surface of axle 200, protrudes, and higher than the upper surface of annular protrusion 210; The size of alignment pin 300 matches with part 10 Kong11 to be press-fited aperture, that is, the diameter of alignment pin 300 can change according to specific requirement, and part 10 to be press-fited is by hole 11 and alignment pin 300 location, part to be press-fited 10 behind location is coaxial with axle, that is to say with clamp body 100 coaxial.

Simultaneously, the external diameter of axle 200 matches with part 20 to be press-fited hole 21, part 20 to be press-fited is set on the projection of axle 200 with respect to clamp body 100, and be placed on clamp body 100, the internal diameter in part 20 to be press-fited hole 21 matches with the external diameter of axle 200, that is to say, the diameter of annular protrusion 210 parts of axle 200 can regulate according to the actual requirements, part 20 to be press-fited is by being set in axle 200 axial alignment with axle 200, because axle 200 is coaxial with part 10 to be press-fited, make

part

10,20 to be press-fited coaxial.

The interior survey on clamp body 100 tops is provided with a circle annular stopper 101, and be provided with accordingly the outside annular stopper of a circle 201 in axle 200 bottom and this annular stopper 101, axle 200 below under the active force of spring 70, by this annular stopper 201, mutually push against with clamp body 100.

The spring 70 that axle arranges for 200 times is placed in clamp body 100, and this spring 70, under off working state, pushes against axle 200 and clamp body 100 (now axle 200 pushes against with clamp body 100 mutually by this annular stopper 201); These spring 70 upper ends are connected with axle 200, and lower end fixes with base 50 by a steady pin 60; Wherein, base 50 centers are offered porose, and steady pin 60 is placed in this hole, that is to say, the spring 70 being placed on this steady pin 60 is coaxial with base 50.

When press-fiting work, part 10 to be press-fited is sleeved on alignment pin 300, part 20 to be press-fited is set on the annular protrusion 210 of axle 200, now axle 200 is depressed, alignment pin 300 overcomes spring 70 and moves downward, and part 10 moves downward, and then press-fits with part 20.Now take off the

part

10,20 having press-fited, axle 200 resets under spring 70 effects, can carry out next round and press-fit.

The utility model can be fast by part registration to be press-fited compression, because part is press-fiting prelocalization accurately and reliably, make that whole to press-fit process stable smoothly, avoided part to place deflection and made in press-fiting process, part to be destroyed, guarantee to press-fit quality, improved production efficiency.
