Detailed Description
Referring to fig. 1 to 6, a high pressure oil pump supporting device includes an underframe 1, a lower supporting member 2, a side supporting member 3 and an upper supporting member 4 which are assembled into a whole, wherein the lower supporting member 2 is installed at the rear end of the underframe 1 through a first bolt 5, the side supporting member 3 is installed at one side of the underframe 1 through a second bolt 6, the upper supporting member 4 is installed at the rear end of the side supporting member 3 through a third bolt 7, a first bottom connecting bolt 8 and a second bottom connecting bolt 9 are respectively arranged on the underframe 1 and the lower supporting member 2 and are used for connecting a gear chamber 10 and the bottom end of a high pressure oil pump 11, and a rear connecting bolt 12 is arranged on the upper supporting member 4 and is used for connecting the top end of the high pressure oil pump 11.
The specific connection mode of the four split parts is as follows:
the rear end face of the underframe 1 is provided with two first threaded holes 13 corresponding to the first bolts 5, the lower support 2 is an inverted L-shaped piece with side rib plates, and the side end face of the lower support 2 is provided with first waist-shaped holes 14 matched with the first threaded holes 13, so that the position of the lower support 2 can be adjusted.
Four second threaded holes 15 corresponding to the second bolts 6 are formed in the end face of one side of the underframe 1, the side supporting piece 3 is an arc-shaped bending piece, a second waist-shaped hole 16 matched with the second threaded holes 15 is formed in the lower portion of the bending portion of the side supporting piece 3, and the position of the side supporting piece 3 can be adjusted.
The upper supporting piece 4 is a transverse L-shaped piece, four third threaded holes 17 corresponding to the third bolts 7 are formed in the side end faces of the upper supporting piece 4, third waist-shaped holes 18 matched with the third threaded holes 17 are formed in the bent upper portions of the side supporting pieces 3, and therefore position adjustment of the upper supporting piece 4 can be achieved.
