The mode for replacing clamping to connect in such a way that connector is fixed.
Further, Fig. 1, Fig. 2 and Fig. 4 are please referred to, the second positioning component 5 includes the second locating piece 51,52 and of positioning column
First fixing piece 53 offers multiple location holes 54 on second locating piece 51, and inserting of being connected to location hole 54 is offered on substrate 1
Hole 8 is connect, positioning column 52 links together the second locating piece 51 and substrate 1 after sequentially passing through location hole 54 and spliced eye 8, then makes
It is with the first fixing piece 53 that second locating piece 51 is fixed tight on substrate 1, wherein also grafting some positioning wherein of locating rod 3
In hole 54.The case where second locating piece 51 is connected to the side of oil-pressure clamp 2, oil-pressure clamp 2 single for installation on substrate 1, two
The two sides that a second locating piece 51 abuts oil-pressure clamp 2 respectively just clamp oil-pressure clamp 2, so that oil-pressure clamp 2 is in substrate 1
On the installation site of X-direction be determined.For being equipped with the feelings of double oil-pressure clamps 2 or more oil-pressure clamps 2 on substrate 1
Condition, each second locating piece 51 is arranged with each oil-pressure clamp 2 interval, so that each oil-pressure clamp 2 is after installation site determines
Holding is parallel to each other.Second locating piece 51 is completed positioning with substrate 1 and is fixed, and each second locating piece 51 successively clamps each oil
After pressing vice 2, just no longer need to individually correct each oil-pressure clamp 2, it is time saving and energy saving, meet hommization and industrialization design.
Preferably, referring to FIG. 1 to FIG. 4, in the present embodiment, the first connecting hole 9 is opened up on the second locating piece 51,
The second connecting hole 10 is opened up on substrate 1, the first connecting hole 9 is connected to the second connecting hole 10, and it is screw that the first fixing piece 53, which is selected, the
One connecting hole 9 and the second connecting hole 10 also open up as threaded hole, by the second fixing piece 62 and base by the way of threaded connection
Plate 1 is fixed together, and structure is simple, convenient for operating and dismount, be easily achieved.Certainly, in other embodiments, riveting also can be used
The mode connect, being clamped substitutes the mode of threaded connection.
Further, Fig. 1 and Fig. 2 is please referred to, the first positioning sleeve 11 is arranged in spliced eye 8, to 11 He of the first positioning sleeve
The processing of positioning column 52 is so that positioning column 52 is inserted into very close to each other after the first positioning sleeve 11, i.e. positioning column 52 and the first positioning sleeve 11
Between cooperate for non-gap, positioning column 52 is inserted into the first positioning sleeve 11 after passing through location hole 54, positioning column 52 and first fixed
Connection between position set 11 prevents positioning column 52 from vibration occurs after positioning the second locating piece 51, so that the second locating piece 51 exists
Installation condition on substrate 1 is more stable.Top is higher than the bottom surface of the second locating piece 51 and is lower than second after positioning column 52 is inserted into
The top surface of locating piece 51, convenient for the top of subsequent the second locating piece 51 of closing that takes measures.As another embodiment, positioning column 52
Top surface of the top with the top surface flush of the second locating piece 51 or higher than the second locating piece 51 after insertion, then be inserted into positioning column
52 the second positioning sleeve 12 no longer needs to take closing measure.
Further, Fig. 1 and Fig. 4 is please referred to, the second positioning sleeve 12, the second positioning sleeve 12 and are arranged in location hole 54
One positioning sleeve 11 is substantially identical but installation site is different, and positioning column 52 is inserted into after the first positioning sleeve 11 convenient for positioning 52 He of positioning column
Grafting between first positioning sleeve 11 occurs vibration after being inserted into location hole 54 to prevent positioning column 52 and is difficult to position and the first positioning
The grafting of set 11.
Further, the quantity of location hole 54 has multiple referring to FIG. 1 to FIG. 4, and one close to oil-pressure clamp 2 wherein
The second positioning sleeve 12 in grafting locating rod 3, the side of locating rod 3 abuts one of end face of the open end of workpiece.Oil pressure
In clamping workpiece, the two sides of workpiece are clamped by the clamping mouth of oil-pressure clamp 2 vice 2, and the both ends of the surface of workpiece are open, positioning
The side of bar 3 abuts one of end face of workpiece, which determines that the end face can be made in the coordinate of X-axis in the coordinate of X-axis
On the basis of number, therefore need to only measure coordinate of another end face in X-axis of workpiece.Locating rod 3 is inserted into the second positioning sleeve 12
Afterwards, the bottom of locating rod 3 is higher than the bottom surface of the second locating piece 51 and the top of locating rod 3 and is higher than the bottom surface of workpiece.
Further, referring to Fig. 1, the top of positioning column 52 and locating rod 3 be fixed with fixed link 13(be not shown in the figure it is fixed
Fixed link 13 on the column 52 of position), after being inserted into positioning sleeve due to locating rod 3,3 regular shape of locating rod directly exerts a force to locating rod 3
Locating rod 3 is taken out and is inserted by inconvenience, therefore fixes a fixed column at the top of locating rod 3, convenient in taking-up and insertion
Stress point is found, human oriented design is met.
Further, referring to Fig. 1, the second positioning component 5 further includes dustproof cover 55, above, we refer to fixed
After position column 52 sequentially passes through the second positioning sleeve 12 and the first positioning sleeve 11, the top of positioning column 52 is lower than the top of the second locating piece 51
Face and the bottom surface for being higher than the second locating piece 51, therefore the top surface of the second locating piece 51 is unclosed, and it is useless to be easily accessible processing iron filings etc.
Therefore dirt using dustproof cover 55 by the top closed of the second locating piece 51, prevents useless dirt from entering in the second locating piece 51, keeps
Cleaning inside second locating piece 51 meets hommization and industrialization design.As another embodiment, after positioning column 52 is inserted into
The of positioning column 52 is then inserted into the top surface flush of top and the second locating piece 51 or top surface higher than the second locating piece 51
Two positioning sleeves 12 no longer need dustproof cover 55 to close.
Further, Fig. 1 and Fig. 5 is please referred to, third positioning component 6 includes multiple briquettings 61 and the second fixing piece 62, pressure
Block 61 is provided with convex block 621, convex block 621 is along 61 direction of briquetting for compressing oil-pressure clamp 2 on substrate 1 on briquetting 61
One end of oil-pressure clamp 2 extends, and the side wall of oil-pressure clamp 2 offers seam allowance 14, and the bottom surface of convex block 621 and seam allowance 14 abut against,
The movement of Z-direction is taken place along to prevent oil-pressure clamp 2.It, will pressure using the second fixing piece 62 after briquetting 61 compresses oil-pressure clamp 2
Block 61 is fixed tight on substrate 1.
Preferably, referring to figure 1, figure 2 and figure 5., in the present embodiment, third connecting hole 15 is opened up on briquetting 61,
