Abstract

The utility model relates to a connecting bolt used for mounting a hydraulic pump, which comprises a rod body and thread disposed on one side of the rod body. The length of the rod body ranges from 125mm to 135mm while the diameter thereof ranges from 14mm to 18mm, the length of the thread ranges from 30mm to 38mm while the diameter thereof is 8mm, and the other side of the rod body is provided with at least two parallel tool clamping surfaces with diameters smaller than the diameter of the rod body. By means of thickening and elongating the rod body and on the premise of keeping the length and the diameter of the thread, the mechanical strength of the connecting bolt is increased, operation space is enlarged as the connecting bolt extends outwards, and the connecting bolt can be reliably mounted on the hydraulic pump and a diesel machine body by aid of a standard wrench, thereby greatly simplifying assembly process. In addition, the connecting bolt is convenient and reliable in operation.

Description

Be used to install the connecting bolt of oil hydraulic pump
Technical field
The utility model relates to a kind of connecting bolt that is used to install oil hydraulic pump, belongs to Diesel Engine Technique Field.
Background technique
On the present little cylinder diameter multi-cylinder diesel engine supporting take turns drag, reaper is provided with oil hydraulic pump, provide power for some need hydraulically powered fittings.Because standard bolt all adopts outer-hexagonal head or hexagon socket head, and the mounting point of oil hydraulic pump on diesel-engine body is limited, when the standard of employing spanner was installed connecting bolt, operation is difficulty relatively.
Summary of the invention
The purpose of this utility model provides a kind of easy for installation being used to that the connecting bolt of oil hydraulic pump is installed.
The utility model is that the technological scheme that achieves the above object is: a kind of connecting bolt that is used to install oil hydraulic pump, comprise shaft and the screw thread that is arranged on shaft one side, it is characterized in that: the length of described shaft at 125~135mm, diameter between 14~18mm, at 8mm, and the shaft opposite side is provided with less than shaft diameter and the parallel tool holder face in two sides at least reach at 30~38mm, diameter.
The utility model improves connecting bolt, and shaft is carried out overstriking, does not change the reach and the diameter of thread, has improved the mechanical strength of connecting bolt.Its shaft of the utility model connecting bolt is provided with the tool holder face less than the shaft diameter, increased the shaft length of connecting bolt in addition, make the connecting bolt extend outwards, and increased installing space, so can adopt the standard spanner just can be installed in connecting bolt reliably on oil hydraulic pump and the diesel-engine body, simplified assembly technology greatly, convenient and reliable operation.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Wherein: 1-tool holder face, 2-shaft, 3-screw thread.
Embodiment
See shown in Figure 1, the utility model is used to install the connecting bolt of oil hydraulic pump, comprise shaft 2 and the screw thread 3 that is arranged on shaft 2 one sides, the length of the utility model shaft 2 is at 125~135mm, diameter is between 14~18mm, screw thread 3 length are at 30~38mm, diameter is at 8mm, increase the mechanical strength of connecting bolt by increasing shaft 2 diameters, and make on the connecting bolt by the shaft length that increases connecting bolt and to move, and the operating space that increase is installed, shaft 2 opposite sides are provided with less than shaft 2 diameters and the parallel tool holder face 1 in two sides at least, can adopt two parallel planes, or four angle head, or hexagon head, can connecting bolt be installed on oil hydraulic pump and the diesel-engine body reliably by the standard spanner.
