Referring to Fig. 3, the workpiece to be processed 200 includes sticking part 110 and hole portion to be drilled 120, the sticking part 110 is in
Tabular, and it is provided with a limiting through hole 1101.The hole portion to be drilled 120 is in coniform, and is matched with the accepting hole 1111, i.e.,
The hole portion to be drilled 120 can be contained in the accepting hole 1111, and can be rotated along the inwall of the accepting hole 1111.In this reality
Apply among example, need to be drilled with two hole to be drilled 1201 in the hole portion 120 to be drilled, between two hole to be drilled 1201 axis
Angle is β, and wherein α is equal with β, and α and β is 90 ° among the present embodiment, that is, needs to be drilled with the hole portion 120 to be drilled
In two holes of " ten " font.
Referring to Fig. 4, when the workpiece to be processed 200 carries out boring work, the hole portion 120 to be drilled is housed first
In the accepting hole 1111, the sticking part 110 is bonded with the mounting surface 111, now the workpiece to be processed 200 is pacified
Position is attached to, XT1 closures, KM1 conductings, KM1-1 disconnects, then by the workpiece to be processed 200 close to 111 turns of the mounting surface
It is dynamic, so that the limit element 20, is then sequentially loaded into by the fixing hole 1112 in the alignment of the limiting through hole 1101 left side
In to the fixing hole 1112 in the limiting through hole 1101 and left side, the workpiece to be processed 200 is fixed on the branch
On support body 10, now XT2 is closed, KM2 conductings, KM2-1, KM2-2 and KM2-4 closure, and KM2-3 disconnects, and then adjusts drill bit pair
The accurate drill guide bores 121, and control drill bit descending, it is described hole to be drilled to carry out first to the workpiece to be processed 200
1201 boring work.When completing Present Borehole work, the limit element 20 is unloaded, due to self-locking action, circuit is unchanged,
Then the workpiece to be processed 200 is rotated close to the mounting surface 111, until being adjusted to the limiting through hole 1101 and right side
The fixing hole 1112 be aligned, and load the limit element 20, now XT3 is closed, KM3 conductings, KM3-1, KM3-3 and
KM3-4 is closed, and KM3-2 disconnects, and the indicator lamp 341 lights, by first hole to be drilled 1201 action of brill before this, you can
Second hole to be drilled 1201 boring work is completed, after being drilled, you can remove the workpiece to be processed 200.
If when the turn hole for completing first workpiece to be processed 200 works, directly the workpiece to be processed 200 is taken
Going out, proximity switch XT1 stops perceiving the workpiece to be processed 200 workpiece in place, and now XT1 disconnects, and KM1 disconnects,
KM1-1 is closed, due to self-locking action, KM2-2 closures, and due to the second proximity switch XT1 do not perceive it is described spacing
Element 20, KM3-2 closures, the alarm 351 will send alarm, and remind operator to leak drilling, if operator will be described to be added
Work workpiece 200 is reloaded on the supporter 10, XT1 closures, KM1 conductings, and KM1-1 disconnects, and the alarm 351 stops
Alarm, then rotates the workpiece to be processed 200 close to the mounting surface 111, until being adjusted to the limiting through hole 1101
Alignd with the fixing hole 1112 on right side, and load the limit element 20, now XT3 is closed, KM3 conductings, KM3-1,
KM3-3 and KM3-4 closures, KM3-2 disconnect, and the indicator lamp 341 lights, by boring first described hole to be drilled 1201 dynamic before this
Make, you can second hole to be drilled 1201 boring work is completed, after being drilled, the workpiece to be processed 200 can be removed,
Because KM3-2 and KM2-3 disconnects, the alarm 351 will not send alarm.
In addition, according to spirit of the present utility model, among other embodiments, if on the workpiece to be processed 200
Need it is inconsistent among the quantity in hole that is drilled with and the present embodiment, accordingly, it is only necessary to opened up on the installing plate 11 pair
The fixing hole 1112 of quantity is answered, and one proximity switch of setting is on the relevant position of each fixing hole 1112
Can, and β angles that the two neighboring fixing hole 1112 and the accepting hole 1111 are formed, it is only necessary to be arranged to it is corresponding adjacent
The α angles of two compositions hole to be drilled are consistent, so as to often be directed at a fixing hole 1112, you can in the workpiece to be processed 200
Relevant position on be drilled with a hole.
To sum up, the Novel drilling frock clamp among the utility model above-described embodiment, when the workpiece to be processed 200 is adopted
When carrying out boring work with the Novel drilling frock clamp, when the workpiece in place proximity switch XT1 stop sensing it is described
Workpiece to be processed 200, and the first proximity switch XT2 and the second proximity switch XT3 fail to sense the limit
During bit unit 20, the alarm 351 will send alarm, to remind operator, and when operator again will be described to be processed
Workpiece 200 is encased on the Novel drilling frock clamp, with to leakage drilling drill when, the alarm 351 will stop
Send alarm, while when completing all boring works hole to be drilled, the indicator lamp lights 341, to remind operator to bore
Complete in hole.Therefore by the Novel drilling frock clamp of setting, the present of Lou drilling can be preferably avoided the occurrence of, is improved
The qualification rate and quality of product.
Embodiment described above only expresses several embodiments of the present utility model, and its description is more specific and detailed,
But therefore it can not be interpreted as the limitation to the utility model patent scope.It should be pointed out that for the common of this area
For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to
In the scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
