The oil pump spacer as defined in claim 5, wherein: division board (2) lateral wall just is located accepting groove (21) and runs through and is provided with slot type hole (25), joint piece (32) width direction's one side is provided with extension piece (322), it is located slot type hole (25) inner chamber to extend piece (322).

7. The oil pump spacer as defined in claim 6, wherein: division board (2) and joint piece (32) are provided with multiunit fixing bolt (22) jointly, all fixing bolt (22) are located division board (2) and keep away from the one side of extending piece (322), division board (2) lateral wall is provided with step groove (24) that are used for accomodating the end of fixing bolt (22).

8. The oil pump spacer as defined in claim 7, wherein: one end, far away from the abutting part (31), of the clamping block (32) is provided with a shock absorption part (33), and multiple groups of deformation cavities (331) are arranged in the shock absorption part (33) at intervals.

9. A process for manufacturing an oil pump separator plate according to any one of claims 1 to 8, wherein: the method comprises the following processing steps: positioning: the clamping block (32) is pressed into the inner cavity of the containing groove (21), and is sequentially in threaded fit with the through hole (23) and the butt joint groove (321) at the lower position through the fixing bolt (22), so that the clamping block (32) is positioned in the containing groove (21); the partition plate (2) is abutted into the inner cavity of the rotor shell (11), and the partition plate (2) is positioned at one group of positioning grooves (111) according to the actual application requirement; fixing: screwing the fixing bolt (22) to enable the rod body of the fixing bolt (22) to be separated from the butt joint groove (321) and the through connecting hole (23) in sequence; at the moment, the clamping block (32) is pushed to abut against the inner cavity of the positioning groove (111) under the elastic acting force of the abutting piece (31), and then an operator sequentially matches the fixing bolt (22) in the through hole (23) and the abutting groove (321) at the higher position in a threaded manner, so that one end of the clamping block (32) is fixed in the inner cavity of the positioning groove (111); screwing the connecting rod (113) to enable one end, close to the isolating plate (2), of the connecting rod (113) to be in threaded connection with the inner cavity of the locking groove (26), so that the isolating plate (2) is fixed in the rotor shell (11); sealing: the isolating block (122) is abutted into the inner cavity of the preformed hole (121) to seal the guide hole (112); and finally, sleeving the rotor shell (11) in the inner cavity of the machine body (1) so that the rotor shell (11) is tightly matched with the inner cavity of the machine body (1).
