[0002] A low-noise automobile engine is a power component on an automobile. During the operation of the low-noise engine, a large amount of heat is generated during the working process of the engine, resulting in a relatively high temperature of the engine. Therefore, in the prior art, in order to cool the engine, a flow channel is opened on the engine, and the engine water pump pumps the coolant into the flow channel of the engine, so as to fully cool the engine in this way. Different from traditional conventional engines, the low-noise automobile engine generates lower noise during the working process.

[0003] The cooling water pump used in an automobile engine is an essential core component during the operation of the automobile engine. During the production and processing of the water pump, the most critical part is the processing of the water pump housing with a special-shaped structure. Specifically, after the engine water pump housing is processed, the impeller can be directly installed to complete the processing of the finished product.

[0043] Embodiment 1

[0044] As Figures 1-5 shown, a positioning tooling fixture for a low-noise automotive engine water pump includes a tooling base 1. (In the existing manner, mounting strip plates 6 are respectively installed on the left and right sides of the bottom of the tooling base 1, and the mounting strip plates 6 are fixedly installed on the workbench through fastening means such as bolts to realize the installation of the work. The mounting strip plates 6 are fixedly installed at the bottom of the tooling base 1 through mounting connecting screw rods). A plurality of locking mechanisms for locking the water pump housing are assembled and connected to the top of the tooling base 1

[0045] Specifically, the center of the top of the tooling base 1 is a loading area 11, and the locking mechanisms are distributed in a circumferential manner around the loading area 11

[0046] Specifically, the locking mechanism includes a lock rod 4. The lock rod 4 includes a rod portion, and a lock convex 411 is integrally formed at the bottom of the inner end of the rod portion. A curved portion 41 is integrally formed at the central portion of the rod portion. The curved portion 41 is rotatably connected to a lock rod seat 44 through a rotating shaft (the lock rod seat 44 includes a rod seat portion rotatably connected to the rotating shaft, and an installation frame portion is fixedly connected to the bottom of the rod seat portion. The installation frame portion is fixedly installed at the top position of the tooling seat 1 through a fastening bolt).

[0047] Meanwhile, a long sliding opening 412 is formed at the outer end of the rod portion. A push sliding rod A is slidably connected in the long sliding opening 412 in a limited manner (a partition cap is threadedly connected to the inner end of the push sliding rod A for preventing detachment). The outer end of the push sliding rod A is fixedly connected to a vertically arranged lifting rod 43. The bottom of the lifting rod 43 is fixedly connected to a sliding column 4311 slidably connected to the tooling seat 1 (correspondingly, a plurality of column holes for slidably connecting the sliding column 4311 are formed in the tooling seat 1).

[0048] Meanwhile, the above-mentioned low-noise automobile engine water pump positioning tooling fixture further includes a driving frame mechanism. The driving frame mechanism includes a driving frame 5 for driving a plurality of the lifting rods 43 to lift synchronously.

[0057] A telescopic spring 34 is sleeved on the vertical screw 32, and the two ends of the telescopic spring 34 are respectively fixedly connected to the bottom of the locking pressing plate 31 and the top of the central limit stud 2.

[0058] When the loading of the water pump housing is completed, at this time, the water pump housing is limited on the central limit stud 2. At this time, the operator screws down the locking pressing plate 31 through the nut. After pressing down, until the four convex seat - pressing seat 33 of the pressing plate 31 are locked and pressed on both sides of the center line part of the housing.

[0059] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples.
