Description

Axial clearance detection equipment

Technical Field

The utility model relates to an axial plunger pump technical field especially relates to an axial clearance check out test set.

Background

The axial plunger pump is a swash plate type axial plunger pump which adopts an oil distribution disc to distribute oil, a cylinder body rotates and depends on variable head variables. The pump adopts the design of the optimal oil film thickness of hydrostatic balance, so that the cylinder body and the oil distribution disc, the piston shoes and the variable head run under pure liquid friction, and the pump has the advantages of simple structure, small volume, low noise, high efficiency, long service life, self-absorption capacity and the like.

The plunger assembly is the important component part of axial plunger pump, and the plunger assembly includes piston shoes 8 and plunger 3, and the piston shoes 8 lower extreme is connected with plunger 3, and the back is processed out to the plunger assembly, need detect whether the axial clearance between piston shoes 8 and the plunger 3 meets the requirements, but does not have corresponding check out test set at present.

Disclosure of Invention

The utility model aims to solve the technical problem that an axial clearance check out test set is provided, simple structure, detection convenience, cost of manufacture are low.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides an axial clearance check out test set, includes base and support, the vertical support of installing in base upper end, the guide pin bushing is installed to this support upper portion one side, guide pin bushing female connection have a slipper base, an inner groovy has been seted up to this slipper base upper end, the bottom central authorities of inner groovy open and have a vertical through-hole, guide pin bushing below be provided with the cardboard, this cardboard middle part is opened has a calorie of hole, the cardboard on be equipped with the word cut-out that blocks the hole intercommunication.

As right technical scheme a supplement, the opening part equipartition at vertical through-hole upper and lower both ends put the round chamfer.

As right technical scheme a supplement, the sliding shoe seat upper portion outside transversely be provided with the screw hole, the downthehole screw in of this screw hole has locking screw.

As right technical scheme a supplement, card hole lower extreme be provided with the bell mouth, the aperture of this bell mouth from top to bottom grow gradually.

Has the advantages that: the utility model relates to an axial clearance check out test set, before the detection, put into the piston shoe seat with piston shoe earlier, the upper portion of piston shoe is detained on the bottom surface of inner groovy, vertical through-hole and guide pin bushing are passed to the plunger, then go into the cardboard along the neck card of plunger in the guide pin bushing below, the neck of plunger cuts open along a word and enters into the cardboard downthehole at last, rotatory piston shoe seat again, with the biggest screw-out guide pin bushing of piston shoe seat, through ruler or other measuring tool, measure the distance between piston shoe seat up end and the guide pin bushing up end, the data contrast standard data of measuring, judge whether qualified in axial clearance. The utility model also has the advantages of simple structure, convenient detection, low manufacturing cost, etc.

figure 4 is a top view of the clip of the present invention.

The figure is as follows: 1. the sliding shoe comprises a base, 2, a support, 3, a plunger, 4, a clamping plate, 5, a guide sleeve, 6, a sliding shoe base, 7, a threaded hole, 8, a sliding shoe, 9, an inner groove, 10, a vertical through hole, 11, an outer thread, 12, a conical hole, 13, a chamfer, 14, a clamping hole, 15 and a straight-line-shaped opening.

Detailed Description

The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.

The utility model discloses an embodiment relates to an axial clearance check out test set, as shown in fig. 1-4, including base 1 and support 2, the vertical support 2 of installing in base 1 upper end, guide pin bushing 5 is installed to 2 upper portions one side of this support, 5 female connection of guide pin bushing have slipper base 6, arranged the external screw thread on slipper base 6's the lateral wall, be provided with on guide pin bushing 5's the inner wall with the internal thread, slipper base 6 upper end seted up an inner groovy 9, the bottom central authorities of inner groovy 9 open and have a vertical through-hole 10, guide pin bushing 5 below be provided with cardboard 4, open at this cardboard 4 middle part has a card hole 14, cardboard 4 on be equipped with the word cut open 15 with card hole 14 intercommunication.

Before detection, a sliding shoe 8 is firstly placed into a sliding shoe seat 6, the upper part of the sliding shoe 8 is buckled on the bottom surface of an inner groove 9, a plunger 3 vertically penetrates through a vertical through hole 10 and a guide sleeve 5, then a clamping plate 4 is clamped into the lower part of the guide sleeve 5 along the neck part of the plunger 3, the neck part of the plunger 3 finally enters a clamping hole 14 along a straight-line groove 15, then the sliding shoe seat 6 is rotated, the sliding shoe seat 6 is screwed out of the guide sleeve 5 to the maximum degree, the distance between the upper end face of the sliding shoe seat 6 and the upper end face of the guide sleeve 5 is measured through a ruler or other measuring tools, the measured data is compared with standard data, and whether the axial gap is qualified or not is judged.
