Description

A kind of anchor clamps that bore the gear fire hole

Technical field

The utility model relates to the machine drilling anchor clamps, is used to bore the gear fire hole.

Background technology

When boring system gear fire hole at present, 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 provides a kind of boring grab that is easy to adjust, its product processed steady quality, and 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 bore the gear fire hole that the utility model provides; Comprise bushing plate (1), latch (2), plug housing (3), axle (4) and the leg (5) that is used to support bushing plate (1); Said bushing plate (1) is horizontally disposed with; The two ends that said axle (4) is passed gear (6) and bushing plate (1) and axle (4) from bottom to top successively are fastening through nut (7) respectively; The supporting nail (8) that is used for Support Gear (6) is installed on the said bushing plate (1), and said plug housing (3) is fixedly mounted on a side of said bushing plate (1), and said latch (2) level is passed plug housing (3) and reached said bushing plate (1) below; The spherical head (2a) of said latch (2) snaps between two teeth of gear (6) gear (6) location, and the position that said bushing plate (1) is gone up corresponding gear (6) fire hole (6a) is provided with fixedly drill bushing (1a).

During installation, the upper surface of gear is spacing through the supporting nail, and the lower surface of gear is spacing through nut, and gear is clamped between supporting nail and the nut and axis location; Simultaneously, the spherical head of latch snaps between two teeth of gear the gear location, has prevented the gear rotation, and drill bit passes from the top down fixedly that drill bushing bores fire hole to gear.

As preferably; Said bushing plate (1) squarely; Said axle (4) is vertically passed the center of said bushing plate (1); Said supporting nail (8) becomes circumference uniform distribution at the center of said bushing plate (1) upper edge bushing plate (1), and the leg (5) that is positioned at said bushing plate (1) below becomes distributed rectangular, makes integral layout more reasonable.

The nut (7) that is positioned at said axle (4) lower end is band shoulder hex nut; Also be provided with open washer (9) between this nut (7) and the gear (6); After Gear Processing is accomplished, only need unscrew hex nut a little, just can move radially open washer open washer is taken out; Again gear is taken out from the lower end of axle, save the complicated work that screws out hex nut fully.

The beneficial effect of this utility model is: the spherical head of using latch instead is decided tooth, clamps in conjunction with supporting nail and nut, thereby gear is accurately located in anchor clamps; Can whether adjust to the right place with definite anchor clamps through the positional precision of latch in the measured material; 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 A-A cutaway view of Fig. 1.

Fig. 3 is the vertical view (not containing gear) of Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described further:

A kind of anchor clamps that bore the gear face fire hole shown in Fig. 1-3 are made up of bushing plate 1, latch 2, plug housing 3, axle 4, leg 5, nut 7, supporting nail 8, open washer 9, locating piece 10, ring washer 11, straight pin 12, screw 13 etc.Bushing plate 1 squarely, be horizontally disposed with, have circular hole on the bushing plate 1 and be used to install and fix drill bushing 1a, fixedly the fire hole 6a position of drill bushing 1a corresponding gear 6 is provided with.Be positioned at totally four of the legs 5 of bushing plate 1 below, become distributed rectangular, four angles of corresponding square bushing plate 1 respectively, four legs 5 are used to support bushing plate 1, and leg 5 is threaded with bushing plate 1.Three supporting nails 8 are installed on the bushing plate 1, and supporting nail 8 becomes circumference uniform distributions along the centers of bushing plate 1, and supporting nail 8 is used for Support Gear 6, makes between upper surface and the bushing plate 1 of gear 6 and leaves the gap.

Axle 4 is passed gear 6 and bushing plate 1 from bottom to top successively, and axle 4 is vertically passed the center of bushing plate 1, and the center of axle 4 overlaps with the center of bushing plate 1.The two ends of axle 4 are fastening through nut 7 respectively; The nut 7 that is positioned at axle 4 lower ends is band shoulder hex nut; Also be provided with open washer 9 between this nut 7 and the gear 6; So that gear 6 is blocked, the diameter of band shoulder hex nut can take out gear 6 after guaranteeing taking off open washer 9 less than the diameter of bore of gear 6 external diameter of open washer 9 smoothly greater than the diameter of bore of gear 6; Be provided with ring washer 11 between nut 7 on axle and the gear 6.

Plug housing 3 is fixedly mounted on a side of bushing plate 1, and both tighten together through straight pin 12, screw 13.Latch, 2 levels pass plug housing 3 and reach bushing plate 1 below, and gear 6 is installed in the below of bushing plate 1, and the spherical head 2a of latch 2 snaps between two teeth of gear 6 gear 6 location.The other end of latch 2 has circular hole and is used to install flexible handle.Pin bushing 14 is housed in the plug housing 2; The middle part of latch 2 is through in the plug housing 3, and wherein one section is the section of being threaded with plug housing 3, and the other end is the tight fit section with pin bushing 14; Increase pin bushing 14, can avoid latch 2 and plug housing 3 to only depend on being threaded to produce in the course of the work becoming flexible.

When gear 6 has keyway, be preferably in and insert locating piece 10 on the axle 4, the lower end of locating piece 10 reaches in the keyway of gear, and is further spacing to gear 6.Then do not need to establish in addition locating piece 10 if on the gear 6 keyway is set.

Like Fig. 1, shown in 2, gear 6 is installed on the axle 4, and the upper surface of gear 6 is leaned on the lower surface of tangible supporting nail 8, and the lower surface of gear 6 is leaned on the upper surface of tangible open washer 9, and the ballhead 2a of latch 2 just snaps between two teeth of gear 6.During installation; At first bushing plate is inverted, is installed leg, axle, gear, plug housing, the height of adjustment latch snaps in the spherical head of latch between two teeth of gear gear is located; Again with bushing plate upset, confirm through measured material that anchor clamps are adjusted to the right place and just can hole.
