Abstract
The utility model discloses a fuel pump with a positioning boss cover plate, and the fuel pump comprises a plate body and a pump body, wherein the pump body is connected with the plate body; the plate body is provided with a positioning boss; and the positioning boss is inserted into a groove which is arranged on the pump body and is adaptive to the positioning boss. According to the fuel pump with the positioning boss cover plate, which is disclosed by the utility model, production working procedures and production cost are saved, and the fuel pump with the positioning boss cover plate has the advantages of convenience in assembling, high product percent of pass and good market competitiveness.
Description
Technical field
The utility model relates to a kind of oil pump, specifically to the cover plate of oil pump.
Background technique
In order to guarantee the rotation flexibility of machine oil pump shaft, what original like products design was adopted is with locating stud positioning housing and cover plate.And the positioning pin hole on the cover plate must adopt the numerical control automatic processing device of band C axle to carry out processing, has brought great manufacture cost and quality cost for like this production and the manufacturing of product.Original product design mainly exists following shortcoming: a, manufacturing, quality cost higher; B, there are unnecessary parts; The quality cost of c, product assembling is higher; D, assembling up-to-standard rate are low, be prone to produce in batches and scrap.
Summary of the invention
The purpose of the utility model is the deficiency that exists to existing technology, and low, easy assembling of a kind of cost and the high oil pump cover plate with positioning boss of product percent of pass are provided.
For realizing above-mentioned model utility purpose; The technological scheme that the utility model adopts is a kind of oil pump with positioning boss cover plate; Comprise the plate body and the pump housing that joins with plate body, said plate body is provided with positioning boss, and positioning boss inserts and is arranged in the groove suitable with it on the pump housing.
Said positioning boss and plate body are one-body molded.
Beneficial effect: the utility model is saved production process and body twines cost, is convenient to assembling, and product percent of pass is high, and the market competitiveness is good.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, further illustrate the utility model, present embodiment is being to implement under the prerequisite with the utility model technological scheme, should understand these embodiments only be used to the utility model is described and be not used in the restriction the utility model scope.
As shown in Figure 1, a kind of oil pump with positioning boss cover plate comprises plate body 1, and plate body 1 is installed on the pump housing 2, on plate body 1, is provided with positioning boss 3 integrated with it, and positioning boss 3 inserts in the groove 4 suitable with it on the pump housing 2.
The utility model is in order to guarantee the concentricity between cover plate and the housing axis hole, cover plate established become stamping part, on the cover board directly stamps out positioning boss, replaces the accurate location of locating stud and housing with this.
Its working principle:
1, the actuation gear of its driving gear drive oil pump turns round by certain direction and rotating speed behind the engine start;
2, the back connection with pump shaft through pin of actuation gear running drives the pump shaft rotation;
3, pump shaft is connected with eccentric rotor through pin and drives the rotation of eccentric internal rotor;
4, eccentric internal rotor and external rotor produce the space of attracting deposit of machine oil through off-centre;
5, attract deposit the space along with the function that oily conversion realizes oil pump is carried out oil suction, compresses and told in rotation.
Its machine oil that spues is to have a certain pressure and a certain amount of, thereby each position that the machine oil that spues is delivered to motor is guaranteed the normal lubricated of motor.
