Abstract
The utility model relates to a drilling limiting device, which comprises an L-shaped depth control rod which consists of a short rod and a long rod; scale marks are engraved on the long rod of the depth control rod; the short rod of the depth control rod is contacted with the top part of a drill bit; the long rod is provided with a clamping structure which can slide along the long rod, can be fastened and is used for clamping a drilling rig body. According to the drilling limiting device provided by the utility model, through the conversion of scale readings of the control rod under different working conditions, presetting of the drilling depth of the drill bit can be accurately realized; a to-be-drilled surface is protected; meanwhile, the contact area of an electric (pneumatic) drill and the to-be-drilled surface is increased, so that the drilling depth can be easily and accurately controlled. Meanwhile, the drilling limiting device has the characteristics that the operation is convenient, and the depth is controlled to be variable.
Description
Technical field
The utility model relates to a kind of boring stopping means, is particularly useful for needing a kind of boring stopping means of strict keyhole degree of depth operating mode.
Background technology
At present, while needing the keyhole degree of depth in manufacturing, use on drill bit binding mark more or add the mode of sleeve.On drill bit, the mode of binding mark is subject to constructor's experience to affect large and accuracy deviation is larger; Though add the mode accuracy of sleeve, be improved, changeability is poor, can not meet the requirement of different drilling depth restrictions.
Utility model content
The utility model main purpose is to address the above problem and is not enough, provides a kind of and can improve accuracy and can meet the boring stopping means that different drilling depths require.
For achieving the above object, the technical solution of the utility model is:
A kind of boring stopping means, comprise a L-shaped severity control bar being formed by quarter butt and stock, on the stock of described severity control bar with graduation mark, the quarter butt of described severity control bar contacts with the top of drill bit, on described stock, be provided with one can along stock slide and can be fastening for clamping the clamping structure of drilling tool body.
Further, described clamping structure forms by clamping pull bar, snap ring and securing member, and one end of described clamping pull bar is threaded double-screw bolt, and the other end has a clamping head, described clamping head is connected with described stock, and described securing member is partly connected with the double-screw bolt of described clamping pull bar with described snap ring.
Further, the openend of described snap ring has two compact heaps, and described compact heap is fixed by described securing member through described clamping pull bar.
Further, described securing member is wing nut.
Further, the quarter butt in described severity control bar is tabular.
Content to sum up; a kind of boring stopping means that the utility model provides; by the conversion of severity control bar scale reading under different operating modes; can accurately realize presetting, protecting and treat boring surface of the bit bore degree of depth; increased electricity (wind) bores and the contact area for the treatment of bore surfaces simultaneously; be easy to the accurate keyhole degree of depth, there is the feature easy to operate, controlling depth is variable simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model patent structure schematic diagram.
As shown in Figure 1, severity control bar 1, quarter butt 1a, stock 1b, clamps pull bar 2, clamping head 2a, double-screw bolt 2b, wing nut 3, snap ring 4, compact heap 5.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail:
As shown in Figure 1, a kind of boring stopping means, comprises a L-shaped severity control bar 1 and a set of clamping structure.
Wherein, severity control bar 1 is comprised of quarter butt 1a and stock 1b, and on the stock 1b of severity control bar 1, with graduation mark, the quarter butt of severity control bar 1 contacts with the top of drill bit with 1a, and for the ease of operation, quarter butt 1a adopts plate-like structure.
Clamping structure is used for clamping drilling tool body, and it is upper that its one end is enclosed within stock 1b, can slide up and down along stock 1b, and can be fastened on the optional position of stock 1b.
Clamping structure forms by clamping pull bar 2, snap ring 4 and securing member, and the one end that clamps pull bar 2 is threaded double-screw bolt 2b, and the other end has a clamping head 2a, and clamping head 2a is enclosed within on stock 1b.Securing member is partly threaded with the double-screw bolt 2b that clamps pull bar 2, and in the present embodiment, for the ease of operation, securing member adopts wing nut 3.The openend of snap ring 4 has two compact heaps 5, on compact heap 5, has through hole, and through hole is through the double-screw bolt 2b part that clamps pull bar 2.By screwing wing nut 3, rely on the fastening force of screw thread that snap ring 4 is fastened on clamping pull bar 2, make clamping head 2a fasten on stock 1b simultaneously.
Describe operating procedure below in detail:
1, before bore operation, unclamp wing nut 3, snap ring 4 is inserted on the body at electricity (wind) brill swivel head rear.
2, severity control bar 1 is pulled down to the flat quarter butt 1a of its front end and contacts with drill bit top, record the scale reading of stock 1b in severity control bar 1 now, this scale reading can be chosen on any body and be labeled as reference point, records this reference point simultaneously.
3, the number of division of measuring in last step is deducted to the thickness of severity control bar 1 front end quarter butt 1a, number of division when obtaining severity control bar 1 face is concordant with drill bit foremost, in conjunction with the drilling depth value that needs to control, by the corresponding scale value that should set on severity control bar 1 that is converted into of this number of division.
4, screw wing nut 3, rely on screw threads for fastening power make snap ring 4 and severity control bar 1 be separately fixed at body and clamp on pull bar 2, making severity control bar 1 and the scale that overlaps of reference point is the above-mentioned setting scale value calculating, and suitably rotate severity control bar 1, make it parallel with drill bit and with drill bit travel path without interference.
5, carry out bore operation, until reach the drilling depth setting.
By the conversion of severity control bar 1 scale reading under different operating modes; can accurately realize presetting, protecting and treat boring surface of the bit bore degree of depth; increased electricity (wind) bores and the contact area for the treatment of bore surfaces simultaneously; be easy to the accurate keyhole degree of depth, there is the feature easy to operate, controlling depth is variable simultaneously.
As mentioned above, given scheme content, can derive similar technical scheme by reference to the accompanying drawings.In every case be the content that does not depart from technical solutions of the utility model, any simple modification, equivalent variations and the modification above embodiment done according to technical spirit of the present utility model, all still belong in the scope of technical solutions of the utility model.
