Embodiment
A kind of batch drilling tool 200 is present embodiments provided, the batch for polygonal mirror supporting cross bearer 100 drills
Operation.As shown in Figure 1, the polygonal mirror supporting cross bearer 100 includes a cylinder steel pipe as girder 110, and along master
Multiple fixed plates 120 of 110 length direction of beam setting.Specifically, in the present embodiment, the polygonal mirror supporting cross bearer 100
110 diameter of girder be 200mm, be provided with 8 fixed plates 120 altogether thereon, the spacing between two neighboring fixed plate 120 is
600mm, and 8 fixed plates 120 are symmetrical as the plane of symmetry using the cross section at 110 center of girder.In each fixed plate 120
Need to drill out three fixation holes, for reflecting mirror to be fixed.By taking the visual angle of Fig. 2 as an example, three fixation holes include being located at admittedly
First fixation hole 121 on the right side of fixed board 120, the second fixation hole 122 positioned at upper left, and the third fixation hole positioned at lower-left
123, and the aperture of three fixation holes is 6.5mm.Wherein, positioned in two fixed plates 120 at 110 center of girder
Distance L is minimum between first fixation hole 121 and girder 110, and the fixed plate 120 closer to 110 both ends of girder, the first fixation hole
121 translations outward, the value of L is bigger, and the L value increment of two neighboring fixed plate 120 is 0.5mm, meanwhile, the second fixation hole 122,
The displacement of third fixation hole 123 is consistent with the first fixation hole 121, to guarantee three fixation hole phases in same fixed plate 120
It is constant to position.
For above-mentioned polygonal mirror supporting cross bearer 100, for fixed plate 120 and fixation hole position accuracy demand compared with
Height, and the position of the fixation hole of every piece of fixed plate 120 has differences, and to realize the drilling production of mass, difficulty is very big
's.
For this purpose, present embodiments provide a kind of batch drilling tool 200, referring to shown in Fig. 3 comprising bottom plate 210 and
Multiple working cells 220, multiple working cells 220 are arranged along the length direction interval of bottom plate 210, and each working cell 220 is
Including vertical plate 221 and drilling equipment 222, vertical plate 221 is for being fixed the position of girder 110 and fixed plate 120, drilling dress
222 are set for drilling to fixed plate 120.In the present embodiment, corresponding with polygonal mirror supporting cross bearer 100, work
The quantity for making unit 220 is 8, and the bore operation of a fixed plate 120 is completed in each working cell 220.

Wall 2214.Bottom wall 2211 is connect with bottom plate 210, and roof 2212 is provided with mounting groove 2215, and mounting groove 2215 runs through the first side wall
2213 and second sidewall 2214.The mounting groove 2215 of multiple working cells 220 is aligned along the length direction of bottom plate 210, common to use
Support is fixed in the girder 110 to polygonal mirror supporting cross bearer 100.When carrying out operation, girder 110 is placed in installation
In slot 2215, the fixation to girder 110 is completed, then fixed plate 120 is close to the first side wall 2213 of vertical plate 221, when each solid
After fixed board 120 is all close to corresponding vertical plate 221, that is, complete the accurate positioning of fixed plate 120.It is noticeable
It is that the position of vertical plate 221 is needed by preparatory adjustment, so that in the case where fixed plate 120 is close to the first side wall 2213, it is adjacent
Spacing between fixed plate 120 is able to maintain in 600mm.Further, the first side wall 2213 is convexly equipped with for fixed plate 120
The boss 2216 being supported, boss 2216 are located at the lower section of mounting groove 2215, and boss 2216 arrives the distance and fixation of girder 110
The distance of plate 120 lower edge to girder 110 is consistent, and when fixed plate 120 is close to the first side wall 2213, the lower edge of fixed plate 120 is rigid
Good to abut with the upper surface of boss 2216, boss 2216 can play the role of positioning and limitation overturning to fixed plate 120.It is fixed
It, being welded and fixed to fixed plate 120 and girder 110 after plate 120 positions.
Preferably, two vertical plates 221 close to 210 both ends of bottom plate are to its main fixed function of the position of girder 110, peace
The width of tankage 2215 should be suitable with the diameter of girder 110, to prevent the shaking of girder 110.Meanwhile because steel pipe straightness
Different because of processing conditions, it is absolute straight not ensure that, the width of the mounting groove 2215 of remaining vertical plate 221 should be slightly bigger than girder
110 diameter, such as 201~205mm can be set by width, clamping and disassembly convenient for girder 110.
As shown in Figure 3 and Figure 4, each drilling equipment 222 includes at least one drilling machine 2221, and is used for drilling machine
2221 are fixed on the drilling machine fixing seat 2222 on bottom plate 210.Each vertical plate 221 is provided at least one location hole 2217,
In the present embodiment, setting is there are three location hole 2217 altogether, the position of three location holes 2217 with need to drill out in fixed plate 120
Fixation hole position it is corresponding.Location hole 2217 runs through the first side wall 2213 and second sidewall 2214, aperture 16mm, hole
It is inside provided with drill jig sleeve (not shown), the outer diameter of drill jig sleeve is identical as the aperture of location hole 2217, and internal diameter is identical as fixation hole, bores
Die sleeve has positioning, guiding role to drill bit.Drilling machine 2221 and location hole 2217 correspond, the drill bit of drilling machine 2221 with it is corresponding
Location hole 2217 be coaxially disposed.In each working cell 220, drilling machine 2221 is respectively positioned on vertical plate 221 in the first side wall 2213
Side, and drill bit is directed toward the first side wall 2213.
Further, the first side wall 2213 and second sidewall 2214 are separately provided for carrying out vertical plate 221 firm
First gusset 2218 and the second gusset 2219.The height of first gusset 2218 is influenced by 2216 position of boss, in order not to hinder
The placement of fixed plate 120, height are lower than boss 2216.Since the drilling of drilling machine 2221 is opened by the side of the first side wall 2213
Begin, stress is larger during the work time for the second gusset 2219.Therefore, the height of the second gusset 2219 is higher than the first gusset 2218
With boss 2216, to increase the height of support as far as possible.
As shown in Figure 3 and Figure 5, bottom plate 210 includes the first end 211 and the second end positioned at both ends on its length direction
212；Multiple working cells 220 are divided into the first working group 220a close to first end 211 using the center of bottom plate 210 as boundary, with
And the second working group 220b close to the second end 212；Multiple vertical plates 221 in first working group 220a are with the first side wall
2213 towards first end 211；Multiple vertical plates 221 in second working group 220b are with the first side wall 2213 towards the second end
212.First working group 220a and the second working group 220b is to cross the section at 210 center of bottom plate as plane of symmetry mirror image each other.Into
When row bore operation, the first working group 220a is opposite with the drill bit drilling direction in the second working group 220b, and symmetrical structure can
So that internal force is cancelled out each other, make entire batch drilling tool 200 more firm.Further, first end 211 is provided with positioning
The bottom of vertical plate 213, positioning vertical plate 213 is connect with bottom plate 210, and positioning vertical plate 213 includes bearing surface 213a, and bearing surface 213a is used
