Description
Technical field
Mould drilling technique field is the utility model is related to, more particularly to a kind of EMUs KK front end-plate hole drilling dies.
Background technology
EMUs KK front end-plates lathe in boring procedure is interfered due to part in the prior art leads to not process, part
The machining accuracy and positional precision in upper each hole are inadequate, have impact on the overall performance and installation precision of front end-plate, extend part
Process-cycle.
The content of the invention
The utility model purpose is to provide a kind of EMUs KK front end-plate hole drilling dies, it can be ensured that Workpiece Machining Accuracy,
Reduction is loaded, and improves operating efficiency, makes up the deficiency that machine tool can not be processed.
The purpose of this utility model is achieved through the following technical solutions：
A kind of EMUs KK front end-plate hole drilling dies, including the upper surface shape identical main body with plate above front end-plate
1, described main body 1 is provided with through thereon, the through hole of lower surface；It is provided with described through hole and is fixed on by pin 2 in main body
Drill bushing 3；Fluted 6 are being opened up with the multistage corresponding section of stairstepping positioning boss 7 on front end-plate in described main body 1, institute
Pad 5 is fixed with the one side connected with front end-plate for the main body stated；Handle 4 is installed on the another side of main body.
The depth of the groove 6 is 4-10mm.
The main body of the hole drilling die is the rectangular parallelepiped structure that middle part carries square hole, and thickness is 15~30mm.
The beneficial effects of the utility model are as follows：
Drilling can be accurately positioned, ensure drilling quality, additionally it is possible to greatly improved drilling efficiency, realize that front end-plate drills
Production in enormous quantities.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is left view of the present utility model；
Fig. 3 is the structural representation of EMUs KK front end-plates；
Fig. 4 is use state figure of the present utility model.
Embodiment
It is described in further details below in conjunction with the accompanying drawings with specific embodiment.
As depicted in figs. 1 and 2, a kind of EMUs KK front end-plate hole drilling dies, including the upper table with plate above front end-plate
Face shape identical main body 1, described main body 1 is provided with through thereon, the through hole of lower surface；It is provided with and passes through in described through hole
Pin 2 is fixed on the drill bushing 3 in main body；In described main body 1 with the multistage corresponding section of stairstepping positioning boss 7 on front end-plate
Fluted 6 are opened up, pad 5 is fixed with the one side connected with front end-plate of described main body；It is provided with the another side of main body
Handle 4.The depth of the groove 6 is 4-10mm.
The main body 1 of the hole drilling die is the rectangular parallelepiped structure that middle part carries square hole, and thickness is 15~30mm.
It is of the present utility model as follows using process：
As shown in Figure 3 and Figure 4, by the one side of the band of hole drilling die of the present utility model fluted 6 with above front end-plate
Plate is alignd, and hole drilling die is fixed on front end-plate using C-shaped clamp, and aluminium is closed by hole drilling die with Φ 10.5mm drill bit
Golden front end-plate is drilled, and after unloading EMUs KK front end-plate hole drilling dies, secondary drilling, aperture are carried out with Φ 11mm drill bit
It disclosure satisfy that diameter in 11.1 ± 0.1mm of Φ requirements.The utility model is simple in construction, operating efficiency is high, processing cost is low, operation
It is convenient, it is only necessary to drill jig is arranged on parts, fixed by C-shaped quick clip, can be according to the operation of people, arbitrarily adjustment
The position of parts, this passes through clamped one time using new, you can completes the processing to each hole on parts, improves operating efficiency
While, the machining accuracy and positional precision in each hole on front end-plate are ensure that, and then improve the overall performance of parts.This practicality
It is new to use aluminium sheet as pad, shape and the main body and the shape phase of front end-plate joint face of pad with aluminium alloy part contact surface
Together, and at the pad of groove hole is offered, pad prevents carbon steel and aluminium alloy from contacting, prevents the corrosion of aluminium alloy, carry
The high-aluminium alloy life-span.
The utility model is grown using iron body service life, is hardly damaged, reduces cost of manufacture.
