Embodiment
In conjunction with accompanying drawing, presently preferred embodiments of the present invention is elaborated.
Referring to Fig. 1 to Fig. 4, PCB mechanical drilling machines 10 of the invention include:Pedestal 1, crossbeam 2, workbench 3, X-axis list
Member 4, Y-axis unit 5, Z axis unit 6, main axle unit 7 and grating scale unit 8.Specifically, there is X-axis unit 4 X-axis straight line to lead
Rail 41 and X-axis motor 42.Y-axis unit 5 has Y-axis line slideway 51 and y-axis motor 52.Z axis unit 6 has Z axis bottom plate 61, Z
Axle line slideway 62, Z axis motor 63 and main shaft folder 64.Wherein, Z axis unit 6 has six by connecting rod 6z installings together,
I.e.:First Z axis unit 6a, the second Z axis unit 6b, the 3rd Z axis unit 6c, the 4th Z axis unit 6d, the 5th Z axis unit 6e and
Six Z axis unit 6f.
For PCB mechanical drilling machines 10, the heater inside machine mainly have tri- axles of X, Y, Z motor 42,
52nd, 63, and the main axle unit 7 for processing.As independent part, the motor 42,52,63 of tri- axles of X, Y, Z, and use
Temperature rise can be controlled by the cooling system carried in the main axle unit 7 of processing.After tested, because X, Y-axis motor 42,
52 carry cooling system, while the influence to machine temperature is limited to part, machine broach machining accuracy are influenceed little.And
The motor 63 of main axle unit 7 and Z axis is distributed on each Z axis unit 6a, 6b, 6c, 6d, 6e and 6f, these Z axis units 6
Pass through connecting rod 6z connection X-axis unit 4.X-axis unit 4 moves integrally, the positioning of X-direction when can complete machine broach, because
Many places thermal source (motor 63 and main axle unit 7 of i.e. each Z axis unit 6) be present on X-axis unit 4 in this.
Because grating ruler reading head 8 and grating scale band 81 be arranged on X-axis unit 4 close to medium position, pass through system control
System, thus X-axis unit 4 position reflection be the point of grating ruler reading head 4 position.And the 6th Z axis unit 6f position
There is the distance that length is L the position of the point of distance grating ruler reading head 4.Because main axle unit 7 and driving on Z axis unit 6
Motor 63 can be generated heat when working, and heat can be delivered on connecting rod 6z, cause connecting rod 6z to heat up, according to the hot expansion property of steel,
Often more than 1 DEG C, 1 meter of length can extend about 11 μm for temperature rise, because of the main axle unit 7 on Z axis unit 6 and the operational heat of motor 63
Influence, connecting rod 6z heating can reach 2 DEG C.For 6 axle machines, about 1.3 meters of L dimension, it is relative to grating ruler reading head 8
About 2x11x1.3 μm of the position maximum elongation of point, i.e., 28.6 μm.That is, for the 6th Z axis unit 6f, because of main axle unit
7 and motor 63 operational heat influence, its positioning precision can 28.6 μm of deviation.This drilling to the 6th Z axis unit 6f
Precision adversely affects.
Found by testing, when environment temperature is 20 ± 1 DEG C, the PCB mechanical drilling machines 10 are only with main axle unit 7 itself
Cooling, the temperature of the shell of main axle unit 7 can reach 28 DEG C, far above environment temperature.Due to the heat of the shell of main axle unit 7
Amount can be delivered on the main shaft folder 64 being in direct contact with it, therefore, it is necessary to be cooled down to main shaft folder 64.
Referring to Fig. 5 to Fig. 8, Fig. 5 is the forward sight structural representation that main shaft presss from both sides in PCB mechanical drilling machines.Fig. 6 is PCB power augers
The plan structure signal that main shaft presss from both sides in the machine of hole.Fig. 7 is the side view structure signal that main shaft presss from both sides in PCB mechanical drilling machines.Fig. 8 is Fig. 7
The sectional structure signal in middle A-A directions.The present invention proposes a kind of temprature control method of main shaft folder 64:Set on main shaft folder 64
There are coolant duct 641, two coolant inlet and outlet 642, and three pipeline processing fabrication holes 643.Wherein, these three pipelines
Processing technology hole 643 is blocked before logical coolant with blocking.This main shaft presss from both sides 64 structures, and temperature can be provided by special equipment
The coolant at 20 ± 0.5 DEG C is spent, the coolant flows through the coolant duct 641 inside main shaft folder 64 so that main axle unit 7
Temperature rise can be effectively controlled.
It is considered that the motor 63 of Z axis unit 6 can also generate heat when working, motor 63 directly connects with Z axis bottom plate 61
Touch, therefore, it is necessary to be cooled down to Z axis bottom plate 61.
Referring to Fig. 9 to Figure 11, Fig. 9 is that Z axis bottom plate shows with the stereochemical structure that main shaft coldplate combines in PCB mechanical drilling machines
Meaning.Figure 10 is the side view structure signal of main shaft coldplate in PCB mechanical drilling machines.Figure 11 is that main shaft is cold in PCB mechanical drilling machines
But the forward sight structural representation of plate.The present invention proposes a kind of temprature control method of Z axis bottom plate 61:Installed on Z axis bottom plate 61 cold
But plate 65 is to control the temperature rise of Z axis bottom plate 61.Coolant duct 651, two coolant inlet and outlet are provided with the coldplate 65
652 and three pipeline processing fabrication holes 653.Wherein, these three pipeline processing fabrication holes 653 are before logical coolant, with stifled
Plug is blocked.This structure of coldplate 65, coolant of the temperature at 20 ± 0.5 DEG C can be provided by special equipment, the cooling liquid stream
Through the coolant duct 651 inside coldplate 65 so that the temperature rise of Z axis bottom plate 61 can be effectively controlled.
Beneficial effects of the present invention include:By using internal logical coolant to cool down, adopted to Z axis bottom plate 61 to main shaft folder 64
Take outside plus coldplate 65 to cool down, the operational heat of motor 63 because of main axle unit 7 and Z axis unit 6 can be effectively reduced, it is right
The temperature rise of main shaft folder 64 and Z axis bottom plate 61 influences, and so as to controls connecting rod 6z temperature rise, it is high-accuracy can be well adapted for pcb board
The needs of processing.
It is noted that it is that coolant duct 641 is set in the inside of main shaft folder 64, via stream in the present embodiment
Coolant through the coolant duct 641 come realize main shaft folder 64 temperature rise control;In other embodiments or at this
Main shaft folder 64 is superimposed coldplate to realize the temperature rise control of main shaft folder 64 behind.Similar, it is at Z axis bottom in the present embodiment
Coldplate 65 is superimposed on plate 61 to realize that the temperature rise of Z axis bottom plate 61 controls;In other embodiments or at the Z axis bottom
The inside of plate 61 sets coolant duct, and the temperature rise control of Z axis bottom plate 61 is realized via the coolant for flowing through the coolant duct
System.
It should be appreciated that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations, to ability
For field technique personnel, the technical scheme described in above-described embodiment can be modified, or it is special to which part technology
Sign carries out equivalent substitution;And these are changed and are replaced, it should all belong to the protection domain of appended claims of the present invention.
