Description
Technical field
The utility model relates to a kind of positioning fixture, particularly a kind of drilling depth positioning fixture.
Background technology
In machining, often carry out Drilling operation, but the difficult problem of the control of drilling depth in processing often, especially when hole depth precision prescribed is higher, operator feels the problem of headache especially, so design dress fixture can accurately guarantee that drilling depth has realistic meaning.
Existing people often draw a mark keyhole degree of depth on drill bit with chalk, precision is too poor; Also have by the scale on drilling machine and control with eyes, although control accuracy increases, precision is difficult to meet high-precision requirement equally.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of simple in structure, easy to use, a kind of drilling depth positioning fixture that can improve machining accuracy and working (machining) efficiency and alleviate labor strength.
For achieving the above object, the technical solution of the utility model is as follows:
A positioning fixture, described positioning fixture comprises the annular clamp body of inner hollow, the lower end of described annular clamp body is provided with annular positioning sleeve, between described annular positioning sleeve and annular clamp body, by bearing, is connected; The outer ring of described bearing is closely embedded in annular clamp body, and the inner ring of described bearing is connected with the interference of annular positioning sleeve; On the sidewall of described clamp body, left and right is arranged with at least two through holes, in described through hole, is provided with hold-down screw; The bottom of described annular positioning sleeve is provided with drill bit installing hole, and the bottom surface of described annular positioning sleeve is provided with three locating detents, and described three locating detents are evenly distributed on the bottom surface of annular positioning sleeve by circumferencial direction.
In an embodiment of the present utility model, described through hole is internal thread through hole.
In an embodiment of the present utility model, described locating detent is welded on the bottom surface of annular positioning sleeve.
In an embodiment of the present utility model, the diameter of described drill bit installing hole is greater than the diameter of drill bit.
By technique scheme, the beneficial effects of the utility model are:
The utility model is simple in structure, easy to use, make drilling depth be guaranteed, improve machining accuracy and working (machining) efficiency, alleviated workman's labour intensity.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model fundamental diagram.
Numeral and the represented corresponding component title of letter in figure:
10, clamp body 11, through hole 12, hold-down screw 20, positioning sleeve 21, drill bit installing hole 22, locating detent 30, bearing 40, drill bit.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Shown in Figure 1, a kind of drilling depth positioning fixture of the utility model comprises the annular clamp body 10 of inner hollow, and this annular clamp body 10 lower end is provided with annular positioning sleeve 20, and this positioning sleeve 20 is for positioning drill bit; Between annular positioning sleeve 20 and annular clamp body 10, by bearing 30, be connected; Bearing 30 outer ring is closely embedded in annular clamp body, and the inner ring of bearing 30 is connected with the interference of annular positioning sleeve, and the size that this interference connects is determined by actual needs.
The utility model left and right on the sidewall of clamp body 10 is arranged with two through holes 11, and it can arrange four according to actual needs; In through hole 11, be provided with hold-down screw 12, hold-down screw 12 can be fixing firmly with drill bit through through hole 11; For the ease of the installation and removal of hold-down screw 12, through hole 11 is herein internal thread through hole.
The utility model is provided with drill bit installing hole 21 in the bottom of annular positioning sleeve 20, this drill bit installing hole 21 and the conducting of clamp body hollow space, and it is for installing drill bit; The diameter of drill bit installing hole 21 is than the general large 0.01-0.03mm of the diameter of drill bit 40; In order to make the utility model drilling depth positioning fixture can meet the demand of different-diameter drill bit, the utility model annular positioning sleeve and annular clamp body is dismountable links together; When needs are installed major diameter or small diameter drill bit, only need to change the annular positioning sleeve coordinating with it, the diameter of annular positioning sleeve bottom drill bit installing hole must be than the diameter of drill bit more greatly.
The utility model is provided with three locating detents 22 on annular positioning sleeve 20 bottom surface, and these three locating detents 22 are evenly distributed on by circumferencial direction on the bottom surface of annular positioning sleeve, stability when it has improved the work of drilling depth positioning fixture.
Shown in Figure 2, operation principle of the present utility model is as follows:
First drill bit is arranged in positioning fixture, drill bit installing hole is passed in one end of drill bit, and is fixed by hold-down screw; When workpiece requires drilling depth to be H, the locating detent end face of fixture being adjusted to the distance of drill end is also H, just can hole to workpiece, when drilling depth arrives H, locating detent just contacts with surface of the work, make drill bit can not continue feeding, thus the depth requirements that the degree of depth of assurance boring equals to adjust in advance.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
