Description
[technical field]
The utility model relates to a kind of machinery processing apparatus, particularly the device processed simultaneously of a kind of internal and external threads of different pitch.
[background technology]
In industries such as maintenance of equipment, machining, machine-building, often need on workpiece body, process external screw thread, perhaps inner hole thread.Yet when the inner hole thread of workpiece body and externally threaded pitch not simultaneously, just need process respectively, exist the problem that inconvenience and precision are difficult to guarantee of processing.For the workpiece of interior tooth pitch greater than outer tooth pitch, traditional diamond-making technique generally is that the internal and external threads of different pitch is processed respectively, soly just need carry out repeated clamping to workpiece, and not only production efficiency is low, and machining accuracy is difficult to control.
[utility model content]
The technical problems to be solved in the utility model, be to provide the overhanging formula of a kind of screw tap inside and outside tooth pitch self adaptation screw die cover, it internally tooth pitch process inside and outside tooth simultaneously greater than the workpiece of outer tooth pitch, avoid repeated clamping, not only production efficiency height, and machining accuracy is easy to control.
The utility model is achieved in that the inside and outside tooth pitch self adaptation screw die cover of the overhanging formula of a kind of screw tap, it comprises a screw die cover, the front end of described screw die cover is provided with a screw die, it also comprises certain piece, a motion block, a screw tap, described screw die cover suit and being fixed in is describedly decided on the piece, described motion block is arranged in the described screw die cover, and the front end of motion block is connected in described screw die by elastic component, described motion block also with axial direction slidably mode be connected in described screw die cover, described screw tap is fixed on the described motion block.
Further, described motion block is connected with described screw die cover with the key ways of connecting.
Further, described motion block is provided with the motion block keyway, and described screw die cover is provided with and the corresponding screw die cover of described motion block keyway keyway, and described motion block cooperates corresponding motion block keyway, screw die cover keyway to be connected to described screw die cover by key.
Further, described motion block is the motion block of middle band square hole, and described screw tap is enclosed within the square hole of described motion block, and is fastened on the described motion block.
Further, described elastic component is a spring.
Advantage of the present utility model is: the utility model is connected in described screw tap on one motion block, described motion block is connected in described screw die cover with the key ways of connecting, and be connected in the screw die that is arranged on screw die cover front end by spring, when drill press spindle drives the rotation of screw die cover, just can drive screw tap rotates, and screw tap can also be under the effect of spring, automatically mate the amount of feeding in actual pitch in overhanging according to internal thread, therefore the utility model can be avoided repeated clamping, clamping promptly internally tooth pitch process inside and outside tooth simultaneously greater than the workpiece of outer tooth pitch, not only enhance productivity greatly, and machining accuracy is easy to control.

[specific embodiment]
See also Fig. 1 to shown in Figure 5, embodiment of the present utility model is described in detail.
As shown in Figure 1, the utility model one embodiment, it comprises certain piece 1, screw die cover 2, one screw tap 3, a motion block 4.The front end of described screw die cover 2 is provided with a screw die 6.Decide piece 1 and be connected on the drill press spindle described, described screw die overlaps 2 suits and is fixed in describedly to be decided on the piece 1, and drill press spindle can drive described screw die cover 2 rotations like this.Described motion block 4 is arranged in the described screw die cover 2, and the front end of motion block 4 by elastic component be arranged on the screw die 6 that screw die overlaps 2 front ends and be connected, described elastic component is a spring 5, the rear end of motion block 4 is to decide piece 1.Described motion block 4 also with axial direction slidably mode be connected in described screw die cover 2, in the present embodiment, described motion block 4 is connected with described screw die cover 2 in the axial direction by adopting the key ways of connecting, and as Fig. 2, Fig. 3, correspondence is provided with two screw die cover keyway 7 on described screw die cover 2; As Fig. 4, Fig. 5, correspondence is provided with and described screw die cover keyway 7 corresponding two motion block keyways 8 on described motion block 4.Described motion block 4 cooperates corresponding described motion block keyway 8, screw die cover keyway 7 to be connected to described screw die cover 2 by key.As Fig. 4, described motion block 4 is the motion block of middle band square hole 9, and described screw tap 3 is fixed on the described motion block 4, is about in the square hole 9 that described screw tap 3 is enclosed within described motion block 4, and uses screw to be fastened on the described motion block 4.
When using, drill press spindle drives described screw die cover 2 rotations, and screw die cover 2 drives described motion block 4 rotations by key and described screw die cover keyway 7, motion block keyway 8, thereby drives screw tap 3 rotations that are arranged on the motion block 4.Because the interior tooth pitch of workpiece is greater than outer tooth pitch, under same rotational speed, the amount of feeding of interior tooth is greater than the outer tooth amount of feeding, be the amount of feeding of the amount of feeding of described screw tap 3 greater than screw die 6, so screw tap 3 beginnings are overhanging, under the resilient force of spring 5, mate the amount of feeding automatically according to the actual pitch of internal thread, so the utility model can process the internal and external threads of interior tooth pitch greater than outer tooth pitch simultaneously.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented according to this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
