Each connecting hole is processed, but traditional Drilling Jig Structure is simple, the complex process for operative employee, labor intensity is larger, knife edge
Need to position by hand by people, it is less efficient.
Utility model content
In order to solve the above technical problems, the purpose of this utility model is to provide a kind of motor machine simple to operate, efficiency high
Shell auger mould.
The technical solution of the utility model is as follows：
A kind of motor case is automatically positioned drill jig, including bottom plate (1), backboard (2), support bar (4) and pressing plate (5), described
Backboard (2) is fixedly installed on the side of the bottom plate (1) by connecting rod (3), and the support bar (4) is symmetricly set on the bottom
On plate (1), the pressing plate (5) is set in the support bar (4) by being fixedly installed on the second sleeve (51) below pressing plate (5)
Outside；Second spring (42) is set between the second sleeve (51) and bottom plate (1), and the spring (42) is set in the support bar
(4) outside；First sleeve (43) is set at the top of the support bar (4), first is set between first sleeve (43) and pressing plate (5)
Spring (41), first spring (41) are set in the support bar (4) outside；
The spring filament diameter of first spring (41), external diameter are more than the second spring (42), and first spring
(41) pitch is less than second spring (42).
Further, pressing plate (5) bottom center sets positioning round table (52), and the side of the positioning round table (52) is set
Limiting section (53) is put, around the multiple drill jig holes (54) of setting centered on the positioning round table (52) on the pressing plate (5).
Further, the backboard (2) sets alignment pin (21) close to the side of the support bar (4).
Further, the alignment pin (21) sets 4 with the central rectangular array of the backboard (2), the positioning
Pin (21) is arranged between 2 support bars (4).
By such scheme, the utility model at least has advantages below：
Positioned in the present apparatus by alignment pin, backboard and positioning round table, and the radiating of casing is blocked by limiting section
Blade, prevent motor case from rotating in process, easy to operate, accurate positioning, ensure drilling precision；The spring of first spring
Silk diameter, external diameter are more than second spring, and pitch is less than second spring, and when two springs are by uniform pressure, deformation quantity is different,
Therefore can be clamped in advance when pressurizeing first time, after work to be operated confirms that motor case clamping is errorless, repressurization, the
One spring deformation amount is smaller, almost unchanged, and second spring continues to compress, further clamping motor casing, ensures punching positioning
Accuracy, fully achieve and be automatically positioned, improve efficiency.

Embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is used to illustrate the utility model, but is not limited to the scope of the utility model.
As depicted in figs. 1 and 2, a kind of motor case described in the preferred embodiment of the utility model one is automatically positioned drill jig,
Including bottom plate 1, backboard 2, support bar 4 and pressing plate 5, the backboard 2 is fixedly installed on the side of the bottom plate 1 by connecting rod 3,
The support bar 4 is symmetricly set on the bottom plate 1, and the pressing plate 5 is by being fixedly installed on the second sleeve 51 of the lower section of pressing plate 5
It is set in outside the support bar 4；Second spring 42 is set between the second sleeve 51 and bottom plate 1, and the spring 42 is set in
Outside the support bar 4；The top of support bar 4 sets the first sleeve 43, and first is set between first sleeve 43 and pressing plate 5
Spring 41, first spring 41 are set in outside the support bar 4；
The spring filament diameter of first spring 41, external diameter are more than the second spring 42, and the section of first spring 41
Away from less than second spring 42.
The bottom center of pressing plate 5 sets positioning round table 52, and the side of the positioning round table 52 sets limiting section 53, in institute
