[specific embodiment]
As shown in Figure 1, pin hole running-in machine of the present utility model comprise guide rod 1, bearing pin 2, with regulating sleeve 3, elastic hollow that guide rod 1 is connected by bearing pin 2 regulate mandrel 6, with elastic hollow regulate mandrel 6 interference fit expander 5, stick on elastic hollow and regulate the Pasting abrasive belt 7 and the control elastic hollow on mandrel 6 surfaces and regulate the lock-screw 4 that mandrel 6 rotates.
The material of regulating mandrel 6 as the elastic hollow among Fig. 2 is the 40Cr of modifier treatment, has the excellent comprehensive performance, this material has good relieving capacity, when being subjected to the situation of radial pressure repeatedly, this relieving capacity can guarantee to return to the original form, and can not make this part torsional deformation when the high speed spin finishing again or phenomenons such as unstability occur.
As shown in Figure 2, the external screw thread 8 that described elastic hollow is regulated mandrel 6 is M10 * 1, is provided with tooth- shape structure 9 and 10 on the right of external screw thread 8, and wherein the number of teeth is 8.External screw thread 8 whenever rotates a circle, they will relative adjustment sleeve 3 axially-movable 1mm, because the number of teeth of tooth- shape structure 9 and 10 is 8, on so every rotation one equal portions, the axially-movable that elastic hollow is regulated mandrel 6 is exactly 0.125mm, and this also is the key that realizes minimum surplus facing-up processing.When elastic hollow is regulated the 3 do rotations of mandrel 6 relative adjustment sleeves near motion, the one end extruding elastic hollow of guide rod is regulated the expander 5 of mandrel 6 the insides, the expansion that expander 5 is produced radially, obtain different dilations by the energy of rotation that continues, thus the pin hole of energy bedding-in different size, different accuracy.
Have axial chip area in the right-hand member cylindrical mandrel of described elastic hollow adjusting mandrel, it is mainly used to get rid of the metal fillings when grinding.
Described teeth groove 10 is that diameter is the semicircular structure of 4mm, and elastic hollow adjusting mandrel is regulated and locked to its main cooperation with lock-screw.
Described regulating sleeve left part is provided with radial direction through hole, is used for installing bearing pin, and moment of torsion is transmitted reliably; Right part is provided with the radially tapped through hole that cooperates with lock-screw.
The end of described lock-screw 4 is that diameter is the hemispherical of 4mm, and the teeth groove 10 of itself and the tooth-shape structure elastic hollow that matches in the process of incompatible assurance facing-up is regulated mandrel 6 and do not made relative rotary motion with regulating sleeve 3.Its structure as shown in Figure 6.
Other embodiment as lock-screw 4 and teeth groove 10, the structure of the structure of described lock-screw 4 or teeth groove 10 can be arbitrarily, so long as elastic hollow adjusting mandrel 6 is not made the scope that relative rotary motion all belongs to the invention with regulating sleeve 3 in the process that guarantees facing-up that can cooperatively interact.
As another embodiment of lock-screw 4, can be screwed in elastic hollow with nut and regulate the end that mandrel 6 contains screw thread, the locking regulating sleeve.
Be arranged at elastic hollow as the expander among Fig. 15 and regulate in the mandrel 6, preferably use butyronitrile (NBR) elastomeric material, can anti-150 degree high temperature, water-fast, oil resistant and air-tightness are all better, also available polyurethane rubber material.
As a kind of improved procedure of guide rod 1, bearing pin 2, regulating sleeve 3, described guide rod 1, bearing pin 2, regulating sleeve 3 can be made of one and be actuating unit, and an end of described guide rod 1 withstands on an end of described expander 5.
Described guide rod 1 is used for transmitting the moment of torsion of various power set outputs, can on plurality of devices, use, equipment such as bench drill, upright drill, radial drill, electric hand drill, internal grinder, lathe, numerically controlled lathe, CNC milling machine for example, it is so long as rely on the anchor clamps of various device to come clamping guide rod 1 to transmit moment of torsion.
As the Pasting abrasive belt 7 among Fig. 1 is that a kind of front has different granularity specifications, and there is the abrasive belt of high temperature resistant adhesive at the back side.Energy operate as normal under adverse circumstances such as high speed, high temperature, machine oil, inorganic salts, saponification liquor, water, the discord elastic hollow is regulated mandrel 6 and is produced disengaging.Normal using method is that the diaphragm with Pasting abrasive belt 7 back sides tears, and evenly is bonded at the inflatable zone that elastic hollow is regulated mandrel 6, in chip area 11 positions it is slit into eight equal portions with paper knife again.
Cut apart for preferred eight equal portions of the dividing method of chip area 11 and Pasting abrasive belt 7, also can select cutting apart of other equal portions.
A kind of improvement as Pasting abrasive belt 7, the grain structure of the positive different granularity specification of similar Pasting abrasive belt 7 can be set on the surface that elastic hollow is regulated mandrel 6, can reach the effect of facing-up equally, and reduce the number of part, reduce cost.
Elastic hollow is regulated mandrel 6 and is rotated in the regulating sleeve 3 of packing into, and the cunning of utilizing guide rod 1, regulating sleeve 3, elastic hollow to regulate the A of mandrel 6, the face of cylinder, B two place connects the concentricity of touching after part is come warranty element guide rod 1 and 6 assemblings of elastic hollow adjusting mandrel.
Operating process of the present utility model is as follows:
1, adjustment process: left hand is held regulating sleeve 3, lock-screw 4 rotations are unclamped, the middle part that the right hand is held elastic hollow adjusting mandrel 6 turns clockwise, lock lock-screw 4 then, the one end extruding elastic hollow of guide rod is regulated the expander 5 of mandrel 6 the insides, the turgor movement that expander 5 is produced radially.
2, expanded pin hole running-in machine is put into pin hole 15, make the differential expansion position of Pasting abrasive belt 7 contact work with pin hole 15 earlier, as shown in Figure 5.Caloric value in the time of not only can reducing facing-up can also guarantee the precision of facing-up.
