Embodiment
With reference to specific accompanying drawing, the utility model is described in further detail.
As shown in figure 1, the measurement apparatus of diesel injection pump fuel delivery command range described in the utility model includes matrix
1, part positioning element and straight line transfer device are installed on matrix 1.
As shown in Figure 1 and Figure 2, the part positioning element includes the first contiguous block 4, and the bottom of the first contiguous block 4, which is set, to be slided
Block 3, sliding block 3 are slidably matched with being arranged on the slide 2 of the upper surface of matrix 1, and being provided for part in the upper surface of the first contiguous block 4 determines
The alignment pin 5 and locating dowel 6, alignment pin 5 and the composition testing fixture positioning datum of locating dowel 6 of position；Set and adjust in the sidepiece of described matrix 1
Bolt 15 is saved, the end of regulating bolt 15 is connected with the first contiguous block 4, is connected by regulating bolt 15 in left and right directions regulation first
Connect the position of block 4；In addition, connecting second spring 14 between first contiguous block 4 and matrix 1, second spring 14 is utilized
Elastic force, reduce impulsive force when part positioning element hits regulating bolt 15 during exercise so that data can more stablize,
Reliably.
As shown in figure 1, the straight line transfer device includes support 10, support 10 is arranged on matrix by the second contiguous block 13
On 1, traveller 11 is set in the mounting hole 17 of support 10, pilot hole 18 is set in the side wall of mounting hole 17, set in pilot hole 18
Measurement head 12 is put, the root of measurement head 12 is inserted in the radial hole on traveller 11, and support 10 is stretched out on the measurement head of measurement head 12
It is outside and towards part positioning element side；It is fixedly mounted in the upper end of the mounting hole 17 by C words circle 7 and holding screw 8
Amesdial 16, the measurement head of amesdial 16 and the top contact of traveller 11；The first spring 9 is arranged at the top of the traveller 11,
C words circle 7 is withstood in the upper end of first spring 9, and the step surface of traveller 11 is withstood in the lower end of the first spring 9.
Facing-up is handled during traveller 11 and mounting hole 17 processing, ensures gap≤0.008mm.The measurement head 12 is with sliding
Radial hole interference fits on post 11.A diameter of 5mm of the measurement head 12, a diameter of 7mm of the pilot hole 18 on support 10,
