Further, described convex ridge is in T shape.
Further, described convex ridge extends in the middle of described shoulder from described main body, and described groove does not penetrate described installing plate external surface.
Concrete, installation cavity and interior step is provided with inside described installing plate, described interior step is fixed with installation cushion block, the long screw being provided with superposed voussoir in described installation cavity, being positioned at the locking cushion block of bottom and described voussoir and locking cushion block are strained, described locking cushion block is held in described installing plate soffit, be clamped with spindle nose between described voussoir and installation cushion block, between two described spindle noses, be articulated with hobboing cutter.
Further, described installation cushion block is fixed by the short screw that two penetrate described interior step.
Further, the corner of described interior step is provided with distortion groove.
Adopt technique scheme, the beneficial effect of technical solutions of the utility model is:
1, the utility model is by the protuberance of the shoulder support installing plate of structural slab, and load mainly relies on the face between protuberance with shoulder contact transmissions, sound construction, avoids solder attach power and causes hobboing cutter case to be hit the problem of easy disintegration not;
2, the cooperation energy limiting structure plate of convex ridge and groove and the relative position of installing plate, connects, because convex ridge and groove do not extend to exposed portion outside hobboing cutter case, so do not affect the integrality of outward appearance both convenient;
3, spindle nose adopts tension mode to be fixed in installation cavity, and structure is simple, easy for installation;
4, be out of shape groove enable two sides, interior step turning have larger angle Light deformation space, prevent installing plate be subject to install cushion block transmission and come impact force and tear.

Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail.
As shown in Figure 1, Figure 2 and Figure 4, a kind of shield machine roller cutter mechanism, the hobboing cutter 3 comprising hobboing cutter case 1 and be located in hobboing cutter case 1, hobboing cutter case 1 is welded by the installing plate 11 of a pair symmetrical configuration and two structure plates 12, installing plate 11 both sides are provided with the protuberance 111 protruded from top, structural slab 12 comprises main body 121 and is located at the shoulder 122 of main body 121 both sides, and protuberance 111 is propped up on shoulder 122.Solder 4 is the engagement edges being connected to installing plate 11 and junction plate 12.Hobboing cutter 3 relies on hobboing cutter case 1 to be installed on shield machine, and in actual use, hobboing cutter 3 is subject to the reaction force of cutting force, then by vibration passing to installing plate 11.Be different from connected mode in the past, the supporting role of structural slab 12 pairs of installing plates 11 mainly relies on the face between protuberance 111 with shoulder 122 to contact, so just instead of with the effect of weak solder 4 for answering load to transmit medium itself, sound construction, avoids solder 4 adhesion stress and causes not hobboing cutter case 1 to be hit the problem of easily disintegrating.
As shown in Figure 1, Figure 2 with shown in Fig. 5, shoulder 122 upper surface is provided with convex ridge 1221, and convex ridge 1221 is in T shape, and protuberance 111 soffit is provided with the groove 1111 for accommodating convex ridge 1221, convex ridge 1221 extends in the middle of shoulder 122 from main body 121, and groove 1111 does not penetrate installing plate 11 external surface.The cooperation of convex ridge 1221 and groove 1111 can limiting structure plate 12 and the relative position of installing plate 11, connects, would not slide over each other both when welding both convenient; Because convex ridge 1221 and groove 1111 all do not extend to exposed portion outside hobboing cutter case 1, so do not affect the integrality of outward appearance.
As shown in Figure 2, installation cavity 112 and interior step 113 is provided with inside installing plate 11, the short screw 25 that interior step 113 penetrates interior step 113 by two is fixed with installation cushion block 21, the long screw being provided with superposed voussoir 22 in installation cavity 112, being positioned at the locking cushion block 23 of bottom and voussoir 22 and locking cushion block 23 are strained, be clamped with spindle nose 31 between voussoir 22 and installation cushion block 21, hobboing cutter 3 is articulated between two spindle noses 31.During assembling, fix respectively by short screw 25 in two installing plates 11 and cushion block 21 is installed, the spindle nose 31 of hobboing cutter 3 both sides is placed in the installation cavity 112 of a pair installation cushion block 21 respectively, then above installing plate 11, voussoir 22 is put into, voussoir 22 is made to contact inclined-plane on spindle nose 31, finally fixed voussoir 22 position by locking cushion block 23 and long screw 24, now spindle nose 31 will clamp by voussoir 22, this completes the installation of hobboing cutter 3 again.
As shown in Figures 2 and 3, the corner of interior step 113 is provided with distortion groove 1131.Under duty, the impact force that hobboing cutter 3 transmission is come can be delivered to interior step 113 near zone by installing cushion block 21, when not offering distortion groove 1131, there is area of stress concentration in interior step 113 corner, easily to tear, distortion groove 1131 makes both sides, interior step 113 turning have larger angle Light deformation space, avoids above problem.
Above-described is only embodiments more of the present utility model.For the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
