Embodiment
In order to which technical characteristic, purpose and effect to the present invention are more clearly understood from, now control illustrates this hair
Bright embodiment.
As shown in figure 1, the present invention is provided in a kind of embedded bearing cutting instrument, the deep hole for cutting ball valve 9
Embedded bearing, the embedded bearing cutting instrument includes being used to cut the cutter arrangement 1 of bearing, for being oriented to cutter arrangement 1
Guider 2 and for drive cutter arrangement 1 rotate drive device 3, guider 2 is connected on ball valve 9, and position
In the outside of cutter arrangement 1, the machine direction for ensuring cutter arrangement 1；Drive device 3 is connected with cutter arrangement 1, can drive knife
Tool device 1, which is rotated, to be cut bearing.
As shown in Figure 2 and Figure 3, in a preferred embodiment, cutter arrangement 1 includes knife cylinder 11 and cutter head 12, knife cylinder 11
Alternatively referred to as columnar handle of a knife, knife cylinder 11 is cylindrical, and one end of knife cylinder 11 is connected with drive device 3, with by drive device 3
Driving is rotated, and guider 2 is circumferentially surrounded in the outside of knife cylinder 11, to carry out guide and limit to knife cylinder 11, makes knife cylinder 11 to right
The direction that fiducial axis is held moves ahead, and prevents knife cylinder 11 from offseting；Cutter head 12 is fixed on the other end of knife cylinder 11, the depth for stretching into ball valve 9
Embedded bearing is cut in hole, installed for example with the cutter head of fixing hole 122 and the knife cylinder 11 of bolt connection cutter head 12
Groove 111, knife cylinder is fixed with cutter head, cutter head 12 has the cutting edge 121 towards bearing to be cut bearing.The present invention is adopted
Fixed cutter head 12 is supported with knife cylinder 11, knife cylinder 11 has such as edge on high-strength structure and very high concentricity, knife cylinder 11
Circumferential and axial are respectively equipped with multiple through holes, for mitigating knife 11 weight of of cylinder itself, make cutting more flexible.
When using cutter head 12 to bearing cutting, according to the width of ball socketed bearing set (or being bearing base), it is not
Bearing is imposed uniformity without examining individual cases, but can be by segment design into different in width, substep is cut, such as is further fixed on cutter block on cutter head,
Cutting edge is set in cutter block, the different-diameter in scope of design can be cut by changing cutter block, cutter block is consolidated by housing screw
It is scheduled on the relevant position of cutter head, by setting cutter block, is easy to need to be changed and allocated according to cutting.
In embodiment as shown in Figure 4, Figure 5, guider 2 includes multiple circumferentially surround in the limit in the outside of knife cylinder 11
Position block, each limited block includes fixed mount 21 and regulating part, and fixed mount 21 is fixed on the valve body of ball valve 9, for example, pass through spiral shell

Gap, directly spacing to knife cylinder 11, guiding.
Again as shown in fig. 7, being specifically, adapter sleeve 22 is inlayed fixed or is socketed in mounting hole 211, and hand includes hand-held 23
Portion 231, first connecting portion 232 and second connecting portion 233, Handheld Division 231 are located at outside adapter sleeve 22, for hand-held, first
Connecting portion 232 has external screw thread, is threadedly coupled for the screwed hole 221 with adapter sleeve 22, so as to by being rotated in adapter sleeve
Moved axially in 22, second connecting portion 233 is fixedly connected with one end of interior silk braid 24 or is connected by left-hand thread, so that in rotation
Hand is that can drive interior silk braid 24 together along the axial movement of adapter sleeve 22 when 23, because the other end and the bistrique 25 of interior silk braid 24 are inlayed
Build-in is determined, i.e. one end of bistrique 25 is fixed in the fixing hole 241 of interior silk braid 24, shape between the other end and the knife cylinder 11 of bistrique 25
Into regulation gap, therefore interior silk braid 24 can be with rotary bistrique 25 together along the axial movement of adapter sleeve 22, to bistrique 25 and knife cylinder 11
Between the size in regulation gap be adjusted, realize that guiding knife cylinder is in fixed interval (FI) to the positioning of knife cylinder, spacing and guiding
Forward stability is advanced, and bearing is steadily cut.
As shown in Fig. 1, Figure 10, Figure 11,11 end of knife cylinder is connected with the rotating shaft of drive device 3 or main shaft by flange 4,
For example, flange 4 is provided with detent 41, for example, grooves of φ 20, the rotating shaft (i.e. transmission main shaft) of drive device 3 is provided with
The positioning plush copper coordinated with detent 41, for example, plush coppers of φ 20, due to passing through between the main shaft and flange 4 of drive device 3
High-precision detent and positioning plush copper connection, accurate positioning can give the rotary cutting energy transmission stabilization of drive device 3
Revolving force is passed to knife cylinder 11 by flange 4, flange 4 again, is advanced with the cutter head 12 on moving knife cylinder 11, to axle in the deep hole of axle sleeve
Hold carry out deep-hole boring；Be additionally provided with the first bolt hole 42 and the second bolt hole 43 on flange 4, the first bolt hole 42 by bolt with
Rotating shaft (i.e. transmission main shaft) connection of drive device 3, the second bolt hole 43 passes through the flange connecting hole on bolt and knife cylinder 11
112 connections.
In a specific embodiment, drive device 3 include motor and the speed changer with motor connection, speed changer with
Cutter arrangement 1 is connected by flange 4, and motor is as power source drive transmission duty, and speed changer is the source of turning moment, is carried
For rotary power, speed change torque passes to flange 4 and knife cylinder 11 by speed changer rotating shaft or main shaft, and knife cylinder again transmits revolving force
Cut to cutter head.By setting speed changer, it is easy to select suitable speed, stabilized driving cutter dress according to the requirement of cutting
1 pair of bearing is put to cut.
Again as shown in figure 1, the embedded bearing cutting instrument of the present invention also includes the cutting position of regulation cutter arrangement 1
Feed arrangement 5 (or being feeding adjusting device), cutter arrangement 1 and drive device 3 are both connected on feed arrangement 5, feeding dress
