Description
Technical field
The utility model relates to machining and uses anchor clamps, is specifically related to a kind of anchor clamps that draw keyway.
Background technology
The high efficiency processing method of gear inner hole key slot is drawn key exactly, and the present keyway anchor clamps that draw adopt coupling gear to decide profile of tooth more, can't detect anchor clamps itself; Can only adopt welding manner that Positioning Gear is fixed after adjusting again according to anchor clamps being adjusted after the product actual measurement that processes, the anchor clamps after the welding cause distortion because of the reason of internal stress again; The anchor clamps use is very unstable; The debugging clamper time is long, unstable product quality, and qualification rate is lower.
The utility model content
The purpose of the utility model provide a kind of be easy to adjust draw the keyway anchor clamps, its product processed steady quality, whether qualification rate is high and before converted products, just can detect anchor clamps and adjust to the right place.
In order to achieve the above object, a kind of anchor clamps that draw keyway that the utility model provides comprise chuck body, fairlead and latch; Said fairlead level is installed in the bottom of chuck body; Said latch vertically is installed in the top of chuck body, and the top of said fairlead has keyway, the axis of said latch and the intersect vertical axis of said fairlead; The lower end of said latch is provided with ballhead, said ballhead be positioned at said keyway directly over.
Said fairlead is by the adapter sleeve of coaxial setting and axle constitutes and axle is positioned at the right side of adapter sleeve; The right-hand member diameter of said adapter sleeve is greater than the left end diameter, and the right-hand member of adapter sleeve is fixed on the chuck body through the screw that circumferentially is uniformly distributed with, and the left end of adapter sleeve passes chuck body and reaches the chuck body left side; The middle part diameter of said axle is greater than the two ends diameter, and the middle part of this axle is fixed together through the screw that circumferentially is uniformly distributed with and the right-hand member of said adapter sleeve, and the left end of this axle is through in the endoporus of said adapter sleeve.Fairlead adopts split-type structural, and design of part is simplified more, is convenient to processing and manufacturing.
The upper end of said latch is provided with flexible handle, on the said chuck body pin bushing is housed, the part that said latch passes chuck body comprise with the section of being threaded of said chuck body and with the tight fit suit section of said pin bushing.Flexible handle can be adjusted latch up and down, and the ballhead of latch is fixed on different height, to adapt to the gear location of various outer diameter; Latch combines the pin bushing tight fit when being threaded with plug housing, cause latch inaccurate to the gear location to prevent thread looseness.
The beneficial effect of this utility model is: the ballhead of using latch instead is decided tooth; Can whether adjust to the right place with definite anchor clamps through the positional precision of fairlead in the measured material and latch; Whether qualified anchor clamps are just can obtain clear and definite detection data before the Machining of Gear keyway, shortened the anchor clamps adjustment time, has improved the product orientation precision; Improved anchor clamps stability, qualification rate is very high.

Fig. 2 is the left view of Fig. 1.
Fig. 3 is the structural representation of the axle of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Like Fig. 1, a kind of keyway anchor clamps that draw shown in 2, form by chuck body 1, fairlead 2, latch 3, screw 5, flexible handle 6, pin bushing 7, straight pin 8 etc.Chuck body 1 is a split-type structural, is made up of riser 1a and plug housing 1b, and plug housing 1b is installed in the top of riser 1a.Fairlead 2 levels are installed in the bottom of riser 1a, the axis horizontal of fairlead 2.The axis of latch 3 is vertical, and latch 3 at first is installed on the plug housing 1b, and plug housing 1b is fixedly mounted on the top of riser 1a again through two screws 5 and two straight pins 9.Riser 1a and plug housing 1b also can be made of one, its difficulty of processing relative complex.
The upper end of latch 3 is the termination, and flexible handle 6 is equipped with at the middle part of termination, the intersect vertical axis of the axis of flexible handle 6 and latch 3, and both are interference fit.Pin bushing 7 is housed in the plug housing 1b, and the middle part of latch 3 is through in the plug housing 1b, and wherein one section is the section of being threaded with chuck body 1, and the other end is the tight fit suit section with pin bushing 7.Increase pin bushing 7, can avoid latch 3 and chuck body 1 to only depend on being threaded to produce in the course of the work becoming flexible.The lower end of latch 3 is provided with ballhead 2a.
The top of fairlead 2 has keyway 4, the intersect vertical axis of the axis of latch 3 and fairlead 2, the ballhead 2a of latch 3 be positioned at keyway 4 directly over.Fairlead 2 is made up of the adapter sleeve 2a and the axle 2b of coaxial setting, and axle 2b is positioned at the right side of adapter sleeve 2a.Adapter sleeve 2a is made up of left and right two ends; The right-hand member diameter of adapter sleeve 2a is greater than the left end diameter; Whole T-shaped, the right-hand member of adapter sleeve 2a is fixed on the chuck body 1 through the screw 5 that circumferentially is uniformly distributed with, and the left end of adapter sleeve 2a passes the left side that chuck body 1 reaches chuck body 1.The middle part diameter of axle 2b is greater than the two ends diameter, and the middle part of axle 2b is fixed together through the screw 5 that circumferentially the is uniformly distributed with right-hand member with adapter sleeve 2a, and the left end of axle 2b is through in the endoporus of adapter sleeve 2a, and the endoporus of adapter sleeve 2a is a through hole.The middle part diameter of axle 2b is identical with the right-hand member diameter of adapter sleeve 2a, makes whole fairlead 2 coordinate attractive in appearance more.
As shown in Figure 3, the top of axle 2b has keyway 4, and keyway 4 is symmetricly set on axle 2b top and connects along the direction of axle 2b parallel axes.Axle 2b go up to remove and to be provided with three screw mounting holes, also is provided with two straight pin installing holes, except that fixing through screw, fixes preventing to relatively rotate between the two through straight pin between adapter sleeve 2a and the axle 2b.
Like Fig. 1, shown in 2, gear 9 is installed on the left end diameter of axle of axle 2b, and the left side of gear 9 is leaned on the right side at tangible axle 2b middle part, and the ballhead 2a of latch 3 just snaps between two teeth of gear 9.
During installation, at first the left end with adapter sleeve is installed on the positioning disk, broaching tool is put in the keyway of fairlead, adjusts the height dimension of broaching tool; Gear is installed on the left end diameter of axle of axle, end face leans on the right side at tangible axle middle part; Rotary moveable spanner, the height of adjustment latch snap in the spherical head of latch between two teeth of gear gear are located; Pulling lathe switch, broaching tool begins to move axially along fairlead, and the blade cutting pinion is pulled out a keyway at the gear internal diameter.
This utility model is not limited to above-mentioned version, and fairlead can be made up of the axle that has keyway separately, and axle is directly installed on the chuck body; The installation of fairlead and chuck body both can be on the right side of chuck body, also can be in the left side of chuck body, when both be mounted on the left side of chuck body the time, gear can directly lean on the tangible chuck body.In a word, so long as simple deformation of the utility model or replacement all drop within the protection domain of the utility model.
