Specific embodiment
The embodiment of the utility model is described further below in conjunction with the accompanying drawings.
The embodiment one of the side wall hole drilling positioning fixture of the tubular workpieces of the utility model：As shown in Figures 1 to 4, this is fixed
Position frock includes a positioning block 1, which ensures that tubular workpieces 2 will not week for tubular workpieces 2 to be carried out with positioning clamping
Cause to position unstable to rotation.Workpiece location hole 11, hole position location structure 12 and clamping part 13 are provided on locating piece 1.
In the present embodiment, locating piece 1 is rectangular block, and workpiece location hole 11 is the blind hole knot extended downwardly by the upper surface of rectangular block
Structure, the setting of blind hole structure be in order to preferably position the position of the areole of tubular workpieces 2, certainly in other embodiments,
Blind hole structure is readily modified as through hole, and sets in the corresponding position of through hole the block step with the block vertically of tubular workpieces 2.
Hole position location structure 12 is arranged on the surrounding side wall of locating piece 1, and the outrigger shaft of each hole position location structure 12
Line is consistent with the axis of the areole to be processed of cylindrical work, so as to which the arc surface of tubular workpieces 2 is located through
Position block 1 is converted into the positioning of the locating piece 1 of rectangular configuration, positions more convenient, positioning accuracy higher.Certainly, should know
It is that the setting of rectangular block in the present embodiment is to match the four of tubular workpieces 2 areoles 21 to be processed, and main purpose is
For each areole 21 to be processed, there are one the support positioning of corresponding flat sidewall, i.e., positioned for each hole position
Structure 12 forms the support positioning surface for supporting hole position location structure to back side wall, and due to tubular workpieces 2, there are four to be processed
Areole 21, and the relative angle of the axis of adjacent two areoles 21 to be processed is 90 degree, therefore just set locating piece 1
Rectangular block is set to, in other embodiments, since the axis in the opposite two side walls hole of tubular workpieces 2 is consistent, size is consistent,
Then in processing, it is thus only necessary to set a planar structure vertical with the axis of corresponding areole that positioning can be realized, this
When, it is necessary to which the feeding length of drill bit 3 is increased, a direct step drills through two side walls hole.Certainly, in other embodiments,
If the areole to be processed of tubular workpieces 2 has multiple, the shape of locating piece 1 can be changed according to actual situation, such as
When areole to be processed is by six, locating piece 1 can be arranged to hexagonal prisms structure, when areole to be processed is eight, can will be determined
Position block 1 is arranged to eight prisms；It simultaneously in other embodiments, can be according to the relative angle between adjacent two side walls hole not
Together, and by the angle of the corresponding two side walls of locating piece 1 be changed, ensure the axis of each areole with it is corresponding fixed
Plane where side wall on the block 1 of position is vertical.
For the location structure 12 of hole position, in the present embodiment, wherein opposite two including being arranged on locating piece 1
Hole position location hole 121 on a side wall, the size of hole position location hole 121 should be slightly larger than the size of areole 21 to be processed, avoid
Drill bit 3 by, and hole position location hole 121 axis it is consistent with the axis of areole 21 to be processed, facilitate the position school of drill bit 3
Standard, so as to ensure the positional precision of areole 21 to be processed, in the present embodiment, hole position location hole 121 is circular hole, in other realities
It applies in example, the structure of hole position location hole 121 can be changed arbitrarily according to the actual needs.It is other opposite on locating piece 1
Side wall is equipped with open slot 13, and the opening direction of the open slot 13 is vertical direction, circular groove section 131 and company including trench bottom
The straight slot 132 on the end face for extending to locating piece 1 of circular groove section 131 is connect, corresponding circular groove section 131 is axis and side to be processed
The consistent hole position locating slot of the axis of cinclides 21, facilitate drill bit 3 by the way that further, the composition of straight slot 132 facilitates and will process
The clamping part that tubular workpieces 2 afterwards take out, in actual production process, after areole machines, it is thus only necessary to two
Finger pinches tubular workpieces 2 at open slot 13, and firmly pulling can take out, and facilitate unloading, the design of open slot 13 both reduced
The unloading of tubular workpieces 2 after the completion of frictional force during 2 clamping of tubular workpieces is again easy to process.Certainly, in other embodiments,
Hole position location structure 12 can be disposed as the hole position location hole 121 of the distribution on the peripheric surface of locating piece 1, be not provided with clamping
Portion is directly protruding into hook areole in tubular workpieces 2 by other instruments and takes out tubular workpieces 2.
In the present embodiment, the internal diameter of above-mentioned workpiece location hole 11 is consistent with the outer diameter of tubular workpieces 2, be so in order to
It realizes when tubular workpieces 2 are fitted into workpiece location hole 11, only passes through rubbing between the side wall of locating piece 1 and tubular workpieces 2
It wipes power and realizes the purpose for clamping workpiece, additional increase clamping tool is not required.Meanwhile the axial dimension of workpiece location hole 11 with
The axial dimension of tubular workpieces 2 is consistent, so can be after tubular workpieces 2 are put into workpiece location hole 11, you can it is fixed to complete
Position and clamping.
In the present embodiment, the material of the locating piece 1 is aluminium alloy, relatively soft, and when clamping is easier to operate.
The embodiment two of the side wall hole drilling positioning fixture of the utility model tubular workpieces 2：With the difference of embodiment one
It is, for same tubular workpieces 2, locating piece 1 can be set to structure as shown in Figure 5, four sides rotating locating blocks 1 is not required
