Description
Technical Field
The utility model relates to a diesel engine test run reprocesses technical field, specifically is a be used for diesel engine fuel pump seat frame to reprocess and use measuring tool.
Background
The fuel pump is a core part of the diesel engine, the fuel pump is installed on a machine body seat frame, and a pump transmission end is connected with a gear chamber to rotate. When the diesel engine works, the crankshaft drives the gear to drive the fuel pump to rotate to provide fuel, and whether the position of the rotating axial lead of the fuel pump is accurately consistent with the position of the axial lead of the gear chamber seat frame hole at the transmission end influences whether the fuel pump can reliably run. In order to ensure the precision of the installation position of the fuel pump, the fuel pump must be reliably and accurately positioned and fastened with the engine body and the gear chamber. When the fuel pump shakes seriously or the connecting piece is damaged during diesel engine debugging, the quality problems related to the three parts can be solved. And respectively carrying out relevant size detection on the related parts by disassembling and inspecting the diesel engine. The main problem is found to be that the engine body fuel pump seat frame is more in poor form and position tolerance precision, the general repairing method is that large-scale detection equipment three-dimensional is needed by detecting the engine body, the fuel pump seat frame on the engine body is repaired and processed according to the measuring result, the workload is high during the engine body repairing, all parts of the diesel engine need to be disassembled, and the repairing efficiency is low. Meanwhile, the machining precision of the fuel pump seat frame of the engine body is improved, the improvement investment on professional equipment is required to be increased, the precision can be guaranteed, the production is influenced, and the cost is high.
Disclosure of Invention
In order to solve the current problem of repairing detection efficiency low, with high costs, the utility model provides a be used for diesel engine fuel pump seat frame to repair with surveying utensil, it can make things convenient for quick completion to repair and detect, and is with low costs.
The technical scheme is as follows: the utility model provides a be used for diesel engine fuel pump seat frame to reprocess with surveying utensil, its characterized in that, it is including surveying the utensil pedestal, survey utensil pedestal both ends and seted up the location pinhole respectively, survey the utensil pedestal through inserting on the location bolt of location pinhole is fixed in the fuel pump seat frame, survey utensil pedestal one end side-mounting has rotatable survey utensil dabber, it has the telescopic movable rod to survey utensil dabber tip cartridge, it is used for locking to survey to install in the utensil dabber the locking screw of movable rod, the cover is equipped with the percentage table installation cover on the movable rod, install the percentage table on the percentage table installation cover.
The measuring tool is further characterized in that an axial locking retainer ring matched with the measuring tool mandrel is arranged on the side face of one end of the measuring tool base body.
Adopt the utility model discloses afterwards, directly will survey the utensil and fix on the fuel pump seat frame, then paste the interior hole face and the outer terminal surface in bearing housing hole with the gauge head of percentage table, rotate and survey the utensil dabber, can record the data that needs, realized convenient quick completion and reprocessed detection, reduce cost.
Drawings
Fig. 1 is a schematic view of the present invention.
Detailed Description
See fig. 1, a be used for diesel engine fuel pump seat frame to reprocess and use measuring tool, it is including surveying the utensil pedestal 1, survey 1 both ends of utensil pedestal and seted up the location pinhole respectively, survey the utensil pedestal 1 and be fixed in on the fuel pump seat frame 3 through the location bolt 2 that inserts the location pinhole, 1 one end side-mounting of utensil pedestal of surveying has rotatable utensil dabber 4, 4 tip cartridge of measuring utensil dabber has telescopic movable rod 5, it installs the locking screw 6 that is used for locking movable rod 5 to survey on the utensil dabber 4, locking screw 6 sets up two, can be better fixed, the cover is equipped with percentage table installation cover 7 on the movable rod 5, install percentage table 8 on the percentage table installation cover 7.
An axial locking retainer ring 9 matched with the measuring tool mandrel 4 is arranged on the side face of one end of the measuring tool base body 1, and the mandrel is guaranteed to rotate without axial clearance.
When detecting the position of the diesel engine fuel pump seat frame 3, firstly, the measuring tool seat body 1 is firmly fixed with the mounting surface of the diesel engine fuel pump seat frame 3 through the positioning bolt 2, the positioning precision of the mounting of the measuring tool seat body 1 is ensured through the positioning bolt 2, the measuring head of the dial indicator 8 is respectively contacted with the inner hole surface and the outer end surface of the gear chamber fuel pump bearing seat hole 10, the axial locking retainer ring 9 is locked, the measuring tool mandrel 4 is rotated by hand and is tightly attached to the measuring tool seat frame, the measuring tool mandrel 4 is ensured to rotate without axial clearance, the concentricity tolerance and the verticality tolerance of the central lines of the diesel engine fuel pump seat and the gear chamber fuel pump bearing seat hole can be respectively measured, the concentricity dimension and the verticality dimension maximum value position direction can be measured by the rotating measuring tool mandrel 4, the mounting positions of the diesel engine fuel pump seat frame and the diesel engine body are adjusted according to the measured data and the deviation direction until the two data meet the drawing requirements, the assembly and disassembly are greatly facilitated, and the repair content is reduced.
