A kind of portable drilling jig for shaft-like parts adjusting means
The present invention relates to boring grab field, a kind of portable drilling jig for shaft-like parts adjusting means.
Fixture is to be used for fixing processing object during machine-building, is allowed to occupy correct position, to accept construction or detection
Device, in a broad sense, any operation in technical process, be used for the device of workpiece is installed rapidly, easily and safely,
All can be described as fixture；Such as weld jig, inspection jig, assembling jig, jig etc., wherein jig is most commonly seen,
When workpiece processed by lathe, drawing specifies in order to make the surface of workpiece to reach dimensions, geometry and with other surfaces
The technology requirements such as relative-position error, must install workpiece and clip before processing；Fixture generally (is determined workpiece by setting element
Tram in fixture), clamping device, to cutter induction element (determine cutter position relative with workpiece or guide cutter side
To), indexing means (make workpiece can complete the processing of several station in once mounting, have circular index device and rectilinear movement point
Degree device two class), the composition such as connecting element and clamp body (clamp base).
Boring grab belongs to the one in fixture, provides convenient, it is simple to drillman when boring grab is mainly holed for workpiece
The carrying out made, according to the difference of drilling-workpiece shape, the design of boring grab is the most different, and wherein, axial workpiece is currently used general
Time, and most of axial workpiece holes adding man-hour requirement, but, current boring grab mostly is plane boring grab,
Curved surface boring grab is the fewest, because curved surface exists the problems such as bad fixing and easy slippage, so bringing great difficulty to curved surface boring
Degree；In consideration of it, the invention provides a kind of portable drilling jig for shaft-like parts adjusting means.

The function of dynamic regulation.
As a further improvement on the present invention, described elevating mechanism include bracing frame, four connecting rods, upper ear seat, lower ear base,
Upper rotational pin, lower rotational pin and two clamping screws；Described bracing frame lower end is respectively arranged with two pillars, bracing frame upper end
It is provided with on crossbeam, and crossbeam and offers square chute, square chute is evenly arranged with spacing hole；Four described connecting rods depend on
Secondary joining end to end into prismatic structure, four small end junctions are arranged in upper ear seat by upper rotational pin, four connecting rod lower ends
Junction is arranged in lower ear base by lower rotational pin, and the left end junction of four connecting rods and right-hand member junction are respectively by a lock
Tightly it is bolted in spacing hole.
Beneficial effects of the present invention: a kind of portable drilling jig for shaft-like parts adjusting means has simple in construction, easy to operate
With the advantage such as cost of manufacture is low；It can realize the function that vertical lifting is moved with horizontal plane, uses convenient.
Accompanying drawing explanation
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the perspective view of the present invention.
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with tool
Body illustrates, and the present invention is expanded on further.
As it is shown in figure 1, a kind of portable drilling jig for shaft-like parts adjusting means of the present invention, including base 1, two
Individual elevating mechanism 2, lifting platform 3, two secondary slide rail 5, two ear mount 6 of 4, two slide blocks, leading screw 7, handwheel 8, nut 9 and
Mounting platform 10, two described elevating mechanisms 2 lay respectively at base 1 left and right sides, and elevating mechanism 2 bottom and base 1
Being connected, elevating mechanism 2 top is connected with lifting platform 3；The secondary slide rail 4 of described two lays respectively at lifting platform 3 left and right sides,
And slide rail 4 is connected with lifting platform 3, slide block 5 is arranged on slide rail 4, and slide rail 4 and slide block 5 serve the effect of guiding；；
Two described ear mount 6 lay respectively at lifting platform 3 both sides medium position front and back, and ear mount 6 is connected with lifting platform 3；Described
Leading screw 7 be arranged in two ear mount 6, and leading screw 7 one end is fixed with handwheel 8, is provided with nut 9 at leading screw 7 medium position,
And nut 9 is provided above connected unit, connected unit is connected with mounting platform 10, and mounting platform 10 left and right sides is respectively with two
Individual slide block 5 top is connected.
As it is shown in figure 1, described elevating mechanism 2 include 201, four connecting rods 202 of bracing frame, upper ear seat 203, lower ear base 204,
Upper rotational pin 205, lower rotational pin 206 and two clamping screws 207；Described bracing frame 301 lower end is respectively arranged with two
