Further, described body is also provided with built-in beam, described built-in beam is provided with some link slots.
Further, described built-in beam is horizontally disposed built-in beam, and described built-in beam is arrange along body radial direction and extend to body both sides, described built-in beam with body axle center for median centre is symmetrical.
Further, described link slot is arranged on described body both sides, the link slot of described body both sides with body axle center for median centre is symmetrical.
Further, described link slot is prolong through " U " type groove of body axial direction.
The utility model beneficial effect:
1. in the utility model, body is also provided with built-in beam, described built-in beam is provided with some link slots.Described built-in beam is horizontally disposed built-in beam, and described built-in beam is arrange along body radial direction and extend to body both sides, described built-in beam with body axle center for median centre is symmetrical.The utility model adopts tooth bar main body overcoat body, and body, by built-in beam stabilization and reinforcement, prevents tooth bar main body from swinging in tapping process.
2. it is columniform through hole that body center described in is provided with radial section, described through hole and described body concentric, described through-hole surfaces is provided with screw thread, described body upper surface is provided with the groove portion be communicated with described through hole, described tooth bar main body is provided with external screw thread, and described tooth bar main body is cooperatively interacted by external screw thread and described through hole internal thread.During use, groove puts into machine oil in portion, and this kind of design makes between tooth bar main body and body proud of sufficient lubrication and cooling, to keep good working order.
3. link slot is prolong through " U " type groove of body axial direction.This kind of design facilitates staff's Fast Installation, and installation place is moved, and screw is locked from top to bottom, for convenience detach.
Accompanying drawing explanation
Fig. 1 is a kind of vertical tapping bar of the utility model perspective view.
1-tooth bar main body in figure, 11-connecting hole, 2-body, 21-groove portion, 3-built-in beam, 31-link slot, connector under 4-, 41-send oilhole, 5-tapping head.
Detailed description of the invention
As shown in Figure 1, the utility model provides a kind of vertical tapping bar, it comprises tooth bar main body 1, body 2, lower connector 4 and tapping head 5, body 2 is cylinder, it is round through hole that body 2 center is provided with radial section, through hole and body 2 concentric, through-hole surfaces is provided with screw thread, body 2 upper surface is provided with the groove portion 321 be communicated with through hole, tooth bar main body 1 is provided with external screw thread, tooth bar main body 1 is cooperatively interacted by external screw thread and through hole internal thread, and tooth bar main body 1 is by through hole through body 2, and tooth bar main body 1 lower end connects tapping head 5 by lower connector 4.Tooth bar main body 1 upper end is provided with connecting hole 11, and connecting hole 11 is for being connected with the rotation output of higher level's power-equipment.As what optimize, lower connector 4 is provided with and send oilhole 41.
When using this tapping bar, first add appropriate machine oil to groove portion 321, modest viscosity answered by this machine oil, tooth bar main body 1 top connecting hole 11 inserts the rotation output of power end, the rotation output of power end can drive tooth bar main body 1 to rotate, and tooth bar main body 1 has rotated relative movement downward or upward in body 2, in moving process, the machine oil in groove portion 321 lubricates the external screw thread in tooth bar main body 1, i.e. immersion oil in the machine oil in groove portion 321.
When tooth bar main body 1 relative lower action after immersion oil, the external screw thread of tooth bar main body 1 contacts with the internal thread in body 2, cause the screw thread of body 2 to be also infected with machine oil, now the thread surface of machine oil between tooth bar main body 1 and body 2 forms oil film, plays the effect of double thread lubrication.
Body 2 is also provided with built-in beam, and built-in beam is provided with some link slots 31.Built-in beam is firmly installed through link slot 31 by screw or other removablies by this built-in beam, and after installing, body 2 is relatively fixing, and now tooth bar main body 1 is when through body 2, swings and all obviously reduces again.Play stable tooth bar main body 1 and reduce its effect swung.
As optimization, built-in beam is horizontally disposed built-in beam, and built-in beam is arrange along body 2 radial direction and extend to body 2 both sides, built-in beam with body 2 axle center for median centre is symmetrical.This kind of method to set up is by built-in beam symmetrical shape, and mounting rail does in process in work, and left and right is stressed also symmetrical, firm better effects if.
Link slot 31 is arranged on body 2 both sides, the link slot 31 of body 2 both sides with body 2 axle center for median centre is symmetrical.The effect of mounting rail stressed symmetry when the method for designing of this kind of link slot 31 plays equally.
Link slot 31 is for prolonging through " U " type groove of body 2 axial direction.Installation place is moved, and screw is locked from top to bottom, for convenience detach.
Finally should be noted that; above embodiment is only in order to illustrate the technical solution of the utility model; but not the restriction to the utility model protection domain; although done to explain to the utility model with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; the technical solution of the utility model is modified or equivalent replacement, all belong to protection domain of the present utility model.
