Abstract

The utility model relates to an automatic tapping clamp. The automatic tapping clamp comprises a chuck and a connecting body, wherein the connecting part comprises a fixing part on the upper portion and a buffering part on the lower portion, the chuck comprises a connecting part on the upper portion and a clamping part on the lower portion, and a mechanical buffering structure is arranged between the connecting part and the buffering part. The automatic tapping clamp can achieve multi-head synchronous tapping operation through tapping drills with different thread pitches, the chuck can contract automatically when one tapping drill fractures, work of other tapping drills is not affected, and the automatic tapping clamp has the advantages of being simple in structure, convenient to use, safe and reliable.

Description

Self-tapping folder
Technical field
The utility model relates to a kind of machine tool accessories, specifically a kind of self-tapping folder.
Background technology
During tapping, need fixture that tapping drill point is lived, fixture is fixed on the lathes such as drilling machine or lathe again, it is gun iron link that current tapping folder and tapping are bored, when this tapping is clipped in bull tapping simultaneously, can only select the tapping that specification is identical to bore, because tapping brill and tapping folder is to be rigidly connected, when tapping, feed speed is different during due to the different same rotational speed of pitch, therefore so just cannot synchronously carry out tapping operation, run into tapping that pitch is different and bore existing tapping folder and just cannot carry out multi-head synchronous tapping; When existing tapping is clipped in multi-head synchronous tapping in addition, bores while fractureing other tapping bore and just cannot work on as tapping wherein, efficiency is lower.
Utility model content
The purpose of this utility model is to provide a kind of self-tapping folder, between chuck and connector, elastic buffer structure is set, chuck can be adjusted up and down when in tapping, thereby realize different pitch tapping and creep into row multi-head synchronous tapping operation, bore the chuck while splitting that fractures and can automatically shrink there is tapping, all the other tapping are bored and can be worked on, and have feature simple in structure, easy to use, safe and reliable.
For achieving the above object by the following technical solutions:
A kind of self-tapping folder, comprise chuck and connector, it is characterized in that: described connector comprises the fixed part on top and the buffer part of bottom, described chuck comprises the connecting portion on top and the clamping part of bottom, between described connecting portion and buffer part, is provided with buffer structure.
Described buffer structure comprises the axial cavity that buffer part bottom is offered, axial cavity body sidewall has spacing slotted eye, connecting portion is contained in axial cavity, connecting portion is provided with the alignment pin coordinating with spacing slotted eye, in buffer part bottom, axially the opening part of cavity is also provided with plate washer, plate washer is arranged on gap location between connecting portion axial cavity body sidewall, on described connecting portion, be socketed with spring, spring lower end contacts with plate washer, the upper end of spring exceeds connecting portion top, alignment pin passes spring and is contained in spacing slotted eye, and spring is fixed on connecting portion.
The utility model will be provided with buffer structure between the buffer part of the bottom of the connecting portion on chuck top and connector, the working condition automatic adjusting position that buffer structure can bore according to the tapping of chuck lower end, thereby the tapping that realizes different pitch is bored and can be worked asynchronously together, when generation tapping brill fractures, chuck automatically upwards shrinks and makes chuck depart from workpiece under the effect of spring, avoids affecting the work that other several tapping are bored.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is internal structure schematic diagram of the present utility model.
The specific embodiment
As shown in Figure 1, 2, a kind of self-tapping folder, comprise chuck 2 and connector 1, described connector 1 comprises the fixed part 11 on top and the buffer part 12 of bottom, described chuck 2 comprises the connecting portion 22 on top and the clamping part 21 of bottom, between described connecting portion 22 and buffer part 12, is provided with buffer structure, described buffer structure comprises the axial cavity 13 that buffer part 12 bottoms are offered, axially cavity 13 sidewalls have spacing slotted eye 14, connecting portion 22 is contained in axial cavity 13, connecting portion 22 is provided with the alignment pin 23 coordinating with spacing slotted eye 14, opening part at the buffer part 12 axial cavitys in bottom is also provided with plate washer 3, plate washer 3 is screwed in gap location between connecting portion 22 and axial cavity 13 sidewalls, on described connecting portion 22, be socketed with spring 4, spring 4 lower ends contact with plate washer 3, the upper end of spring 4 exceeds connecting portion 22 tops, alignment pin 23 passes spring 4 and is contained in spacing slotted eye 14, and spring 4 is fixed on connecting portion 22.
The utility model is fixed on the fixed part on connector top on lathe while using, and during separate operaton, the utility model and existing common tapping folder do not have essential distinction; In multi-head synchronous tapping effect industry, the utility model is because centre is provided with buffer structure, the synchronous working of boring applicable to the tapping of different pitch, due to pitch does not coexist the degree of depth of same rotational speed lower feeding can be different, due to the buffer structure between chuck and connector, each tapping is bored can be operated in different deep operations simultaneously, and tapping completes speed does not affect the operation that other tapping is bored yet; And in tapping operation process as tapping occurs bored while fractureing, the chuck contraction that can make progress under the effect of lower spring, makes chuck disengaging work, avoids affecting the work of other tapping brill.
The utility model by arranging buffer structure between chuck and connector, overcome the deficiency of existing tapping folder, realized the synchronization job that different pitch tapping are bored, the existence of buffer structure also reduces the possibility that fractures that in tapping process, tapping is bored, generation tapping can make chuck disengaging work after boring and fractureing automatically, avoids the generation of accident, the utlity model has feature simple in structure, easy to use, safe and reliable.
The utility model buffer structure is not limited to above-mentioned this structure, realizes the structure between connecting portion and buffer part with buffering effect also should belong to the utility model protection category by alternate manner.
