Background
The plunger assembly (shown in fig. 3) is widely applied to pump machines such as variable displacement pumps, the plunger assembly has the requirement on the axial clearance between the plunger body and the sliding shoe, the clearance is generally controlled between 0.02 and 0.05, if the axial clearance of the plunger body assembly after closing in is too large, the volumetric efficiency of the hydraulic pump is reduced, meanwhile, an oil film is difficult to build between the sliding shoe and the swash plate to form a static pressure support, and dry grinding is caused between the sliding shoe plane and the swash plate plane to cause the functional failure of the sliding shoe in severe cases, so that the hydraulic pump cannot work. Therefore, the height of the spherical center of the sliding shoe serving as one of the plunger assemblies is an important link for ensuring the axial clearance of the plunger assemblies, if the spherical center of the sliding shoe is measured by adopting three coordinates, firstly, measurement inaccuracy is likely to be caused due to different positions and points of each sampling point, secondly, 9 sliding shoes are arranged in each hydraulic pump, if the spherical center of the sliding shoe is measured by adopting three coordinates, the whole measurement process time is too long due to the fact that the three coordinates are measured, and the common resources of three-coordinate measurement of other parts are occupied.

Detailed Description
The essential features and advantages of the utility model will be further elucidated with reference to the examples, without however being limited to the embodiments listed.
As shown in fig. 1 to 3, a special measuring tool for measuring the height of the center of a slipper ball of the present embodiment includes a base 1, a measuring rod 2 and a handle 3, wherein the base 1 has a bracket 11 and a supporting plane 12, and the base is U-shaped in this embodiment. The measuring staff 2 is arranged in the mounting hole 13 of the bracket 11 above the support plane 12. The upper end face of the mounting hole 13 is provided with a stop end 14 and a through end 15, and a height difference H is formed between the stop end 14 and the through end 15. The end of the measuring rod 2 is provided with a ball head 4, and the size of the ball head 4 corresponds to that of the spherical part of the plunger body. The handle 3 is arranged on the measuring rod 2, the handle of the embodiment is perpendicular to the measuring rod, and the handle 3 is provided with an anti-slip part 31, so that the user can conveniently hold the handle. The handle 3 is positioned in the side hole 16 of the bracket 11, the side hole 16 is communicated with the mounting hole 13, and the handle 3 drives the measuring rod 2 to move in the mounting hole 13. In the technical scheme, the mounting hole of the base and the outer circle of the measuring rod are assembled in a clearance fit mode. When the blank is clamped, the handle 3 is pulled upwards, the measured piece 10 is placed below the ball head of the side rod 2 opposite to the supporting plane 12 of the base 1, and then the ball head of the side rod 2 is placed into the ball socket of the measured piece 10. After the blank is clamped, if the upper end face of the measuring rod is formed between the base through end 15 and the stop end 14, the size of the spherical center of the sliding shoe is judged to be qualified at the moment, and if the upper end face of the side rod is not formed between the base through end 15 and the stop end 14, the spherical center of the sliding shoe is judged to be unqualified at the moment. Through the technical scheme, the situation that the measurement part of the spherical center of the sliding shoe is accurate due to the fact that the positions of the adopted points of the three-coordinate ball head are inconsistent with the frequency of the adopted points can be avoided, the time for measuring the spherical center height by the three-coordinate sliding shoe in the past is 1 minute and 20 seconds, the time for measuring the spherical center height at present is 15 seconds, time is saved, and the efficiency of parts is improved. And thirdly, the excessive occupation of common resources with three coordinates is avoided, the measurement time is saved for processing other parts, and the processing efficiency of other parts is improved.
In this embodiment, the height of the center of the slipper is L, where l=10 (+0.1, 0), the height difference H between the through end 15 and the stop end 14 is equal to l2±0.003, and L2 represents the dimension of the center of the slipper after the compression by the nominal tolerance dimension, in this embodiment l2=0.08±0.003. The measuring staff 2 is arranged perpendicular to the support plane 12. The stop end 14 and the through end 15 are convexly arranged on the upper surface of the bracket 11, thereby being convenient for identification. A connecting part 5 is arranged between the ball head 4 and the measuring rod 2, so that the ball body and the measuring rod can be firmly connected. The upper end surface 21 of the measuring rod 2 is a plane, so that the position of the measuring rod is convenient to judge, and the positions of the opposite through end and the stop end can be judged through a feeler gauge or a nail cover.
The special measuring tool for measuring the height of the spherical center of the sliding shoe has the advantages of compact structure, ingenious configuration, simple and practical design, and quick measurement and easy judgment.
