Abstract
Lockpin hole positioning fixture of differential mechanism shell relates to a positioner. Two guide structure that the three location structure, drill bushing and the guide pin bushing that become through base, waist hole and bolt positioning group are constituteed and constitutes a compact structure by screw the nut and screw rod realize the operation that quick locating clip is tight, and it is good that it has a simple structure, convenient operation, positioning accuracy, and the machining precision is high, and stable advantage such as strong has not only improved the product percent of pass, has reduced intensity of labour moreover, has improved production efficiency.
Description
Technical field
The utility model is related to a kind of positioner, particularly to the lockpin hole positioning fixture of differential carrier.
Background technology
The existing mode determining movable differential carrier latch-locking hole site includes telescopic Drilling Jig Structure and convertible
, because structure is different with positioning mode, often the underproof situation of lock pin hole location in Drilling Jig Structure, and its operating procedure is multiple
Miscellaneous, positioning precision is poor.
Content of the invention
In view of the shortcomings of the prior art, the purpose of this utility model is that the lockpin hole providing a kind of differential carrier positions
Fixture, it passes through the structure of three positioning, two guiding and a compression, solves existing apparatus step complexity, positioning precision
The problem of difference.
The utility model be employed technical scheme comprise that：A kind of lockpin hole positioning fixture of differential carrier, technical points
It is to use including the base plate with positioning sleeve, the handle with dowel hole, upper guiding support arm and lower guiding support arm and retaining element
Screw rod, the lower end of differential carrier is plugged in the positioning sleeve on base plate, and the lower end of fastening screw is plugged on base plate, handle
The lock pin in the hole of upper guiding support arm is provided with drill bushing, drill bit pass through lockpin hole after with positioned at lower guide on support arm with guide pin bushing
Hole is just right.
As a kind of preferred version of the present utility model, nut is fixed on screw tip, in the connecting portion of nut and screw rod
Position is additionally provided with open washer.
As another kind preferred version of the present utility model, described base plate is fixed by screw.
The utility model advantage is：The lockpin hole positioning fixture of this differential carrier, by base, waist hole and latch positioning group
Become three location structures, drill bushing and guide pin bushing composition two guide frames and by tightening nut and screw rod form one compression tie
Structure, realizes the operation of fast positioning clamping, its have structure be simple and convenient to operate, positioning precision good, machining accuracy is high, stable
The advantages of property is strong, not only increases product percent of pass, and reduces labour intensity, improve production efficiency.
Brief description
In order to be illustrated more clearly that the utility model embodiment or technical scheme of the prior art, below will be to embodiment
In required use accompanying drawing be briefly described it should be apparent that, drawings in the following description are only of the present utility model
Some embodiments, for those of ordinary skill in the art, on the premise of not paying creative work, also can be according to these
Accompanying drawing obtains other accompanying drawings.
Fig. 1 is the structure sectional view of the lockpin hole positioning fixture of differential carrier in the utility model embodiment；
Fig. 2 is the stereogram of the lockpin hole positioning fixture of differential carrier in the utility model embodiment；
In figure number explanation is as follows：1 positioning sleeve, 2 handles, guiding support arm on 21, guide for 22 time support arm, 23 dowel holes,
24 lockpin holes, 3 fastening screws, 4 guide pin bushings, 5 drill bushings, 6 open washers, 7 nuts, 8 base plates, 9 screw rods.
Specific embodiment
So that above-mentioned purpose of the present utility model, feature and advantage is become apparent from understandable, below in conjunction with the accompanying drawings 1, Fig. 2 and
Specific embodiment is described in further detail to the utility model.
Embodiment 1：
The lockpin hole positioning fixture of the differential carrier in the present embodiment, as shown in figure 1, include the base plate with positioning sleeve 1
8th, dowel hole 23, upper guiding support arm 21 and the lower guiding handle 2 of support arm 22 and the screw rod 9 of retaining element, differential mechanism are carried
The lower end of shell is plugged in the positioning sleeve 1 on base plate 8, and the lower end of fastening screw 3 is plugged on base plate 8, and the upper guiding of handle 2 is propped up
Be provided with drill bushing 5 in the lockpin hole 24 of arm 21, drill bit pass through lockpin hole 24 after with positioned at lower guiding support arm 22 on guide pin bushing 4
Hole just right.
The present embodiment utilizes the process of the lockpin hole positioning fixture positioning of differential carrier as follows：
First differential carrier is put into the installation in the hole (first positioning) of the base plate 8 with positioning sleeve 1, by handle 2
On lower end insertion base plate 8, another installing hole is fixed (second positioning), and the lower guiding support arm 22 of handle 2 is inserted differential
In the waist hole of device shell, then the dowel hole 23 of handle 2 is inserted into fastening screw 3 again（3rd positioning）；By drill bushing 5 with lead
Set 4 draw just it is ensured that drill bit under the guiding of drill bushing just to lower guiding support arm 22 on hole（2 guiding）, then tightening nut 7 makes
Movable differential carrier is fixed（One compression）, so far complete positioning clamping work, as shown in Figure 2.
Embodiment 2：
The present embodiment is with the difference of embodiment 1：The nut 7 of the present embodiment is fixed on the top of screw rod 9, for right
Differential carrier is fixed.It is additionally provided with open washer 6 in the connecting portion of nut 7 and screw rod 9.
Described base plate 8 is fixed by screws on the radial drill workbench of level.
