The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Embodiment 1
The hole processing and fixing device of a kind of workpiece as shown in Figure 1, comprise square main board 2, square main board 2 left sides are positioned at the location division 3 that two edges are equipped with evagination, in location division 3, be provided with vertical tapped through hole 4, described square main board 2 upper surfaces are provided with the location and installation groove 6 of indent, location and installation groove 6 middle parts are provided with vertical locating dowel 7, and described square main board 2 is also provided with a plurality of drill bit bore 8 at location and installation groove 6 bottom lands.
The present embodiment is when application, the upper surface that workpiece need to be holed coordinates clamping with location and installation groove 6, vertically locating dowel 7 is through workpiece main aperture location, again square main board 2 upsets are positioned on drilling machine, and coordinate square main board 2 fixing with vertical tapped through hole 4 by standing screw, finally adopt again fixture by workpiece and square main board 2 integral clamps, can hole, during boring owing to being provided with drill bit bore 8 at location and installation groove 6 bottom lands in advance, the position of drill bit bore 8 and quantity are carried out accurate distribution according to the concrete boring requirement of workpiece, thereby can be by the corresponding drill bit bore 8 of drill bit when boring, through 8 pairs of workpiece of drill bit bore, hole, thereby removed from, workpiece is looked for to benchmark, draw the loaded down with trivial details operation of datum line and alignment, and because the mutual dimensional accuracy of drill bit bore 8 is in advance higher, take drill bit bore 8 as the mutual dimensional accuracy in hole that benchmark gets out also very high, in the present embodiment, fixture structure is simple, and cost is low, easy and simple to handle, and machining accuracy is high, practical.
Embodiment 2
The present embodiment has increased following structure on the basis of embodiment 1: former and later two end faces of described square main board 2 are provided with clamping slot 1.
Clamping slot 1 in the present embodiment, for clamping square main board 2, prevents that square main board 2 is because location division 3 locate failures rotate in horizontal plane, the impact of square shaped main board 2 when workpiece is subject to revolving force in the time of also reducing boring.
The present embodiment has increased following structure on the basis of embodiment 1: described square main board is provided with message board 5 between 2 Liang Ge location divisions, upper surface 3.
Message board in the present embodiment can be fastened on square main board 2 by bonding, riveted joint or screw, can the applicable information such as workpiece model, aperture or the hole range of work of notebook device on message board 5, when being convenient to staff and using, distinguish.
The present embodiment has been optimized vertical locating dowel on the basis of embodiment 3, is specially: described vertical locating dowel 7 upper ends are provided with screw thread.
The present embodiment arranges screw thread in vertical locating dowel 7 upper ends, square main board 2 is after the workpiece of having good positioning, and vertically locating dowel 7 upper ends, with adding and threaded engagement nut, are clamped on workpiece in location and installation groove 6 completely, to guarantee workpiece firm position, reduce hole machining deviation.
The present embodiment square shaped main board on the basis of embodiment 1 is further optimized, and is specially: the thickness of described square main board 2 is not more than 5 centimetres.
In the present embodiment, consider that drill bit its working position that stretches into workpiece when drilling deep hole is longer; drill bit very easily interrupts; when the thickness of square main board 2 larger; the length that drill bit stretches into workpiece processing through drill bit bore 8 is just longer; so in order to protect drill bit, the thickness of square main board 2 is unsuitable excessive; so the thickness of the square main board 2 in the present embodiment is not more than 5 centimetres, also can reduce cost.
