Description

Technical Field

[0001] The utility model belongs to the technical field of automobile engine water pump processing, in particular to a low-noise automobile engine water pump clamp. Background Art

[0002] During the operation of a car engine, since the engine is a heat engine, the temperature of the engine cylinder will increase significantly during the engine operation, causing the engine temperature to be too high. When the temperature is too high, the engine is very likely to malfunction. Therefore, in the prior art, a water pump for cooling the engine is installed on the car, and the water pump pumps coolant into the cooling channel opened in the engine cylinder to cool the engine. In order to reduce the noise generated during the operation of the water pump, the prior art reduces the noise by improving the water pump assembly, such as by installing buffering and noise reduction structures such as springs on the bracket on the assembly. In this way, the comfort during vehicle use is increased.

[0003] The main structure of an engine water pump, such as a noise-reducing type, consists of a pump body and a bracket mounted on the pump body to form a water pump assembly. The pump body includes a casing and an impeller mounted within the casing. During operation, the rotating impeller generates centrifugal force to pump the cooling medium.

[0004] Since the water pump shell is a highly irregular shell workpiece, if a hole needs to be drilled on the pump body during the processing, the highly irregular pump shell needs to be positioned and locked. However, the highly irregular pump shell is difficult to position in the first place, and the positioning pressure plate and the highly irregular shell cannot be fully locked.

[0005] Secondly, the current tooling mostly uses a cylinder to drive the pressure plate to position. During the lifting process of the cylinder, the guide rod on the pressure plate increases in wear (for example, during the horizontal pushing process, the increased wear of the guide rod leads to reduced pushing accuracy, which in turn leads to the inability to subsequently statically lock to the corresponding locking position on the shell). This exacerbates the inability of the lifting pressure plate to statically press on the shell. After the contact and pressure, the pressure point position is offset, and the shell with high anisotropy has reduced contact and pressure accuracy, resulting in the stability of the contact and pressure locking being greatly reduced as the tooling is used for an extended period of time, resulting in the shell workpiece being unable to be effectively locked. Utility Model Content

[0006] Based on the above background, the purpose of the present invention is to provide a low-noise automobile engine water pump fixture.

[0007] In order to achieve the above objectives, the present invention adopts the following technical solutions:

[0008] A low-noise automobile engine water pump fixture comprises a fixture base, a top of which is provided with a plurality of chute structures, wherein the chute structures are respectively equipped with a housing locking mechanism connected to a locking water pump housing;

[0009] The housing locking mechanism includes a driving slide slidably connected in a slide groove structure, a locking cylinder is fixedly assembled and connected to the top of the driving slide, and a locking claw is installed on the piston rod of the locking cylinder;

[0010] The housing locking mechanism further includes a roller pulley assembly rollingly arranged on the locking claw, the roller pulley assembly including a plurality of roller pulleys rolling on the top position of the locking claw, the roller pulleys being mounted with a wheel frame, and the wheel frame being fixedly connected to a fixed slide column fixedly mounted in the slide groove structure;

[0011] The housing locking mechanism further comprises a horizontal pushing cylinder for pushing the driving slide to move, and during the pushing process, the rolling pulley rolls against the locking claw.

[0012] Preferably, the chute structure includes a main chute portion, and limiting chute portions are integrally formed on both sides of the main chute portion;

[0013] The driving slide comprises a main seat body portion slidably connected to the main groove portion, and two sides of the main seat body portion are integrally formed with limiting portions that slide within the limiting groove portion with limited position;

[0014] The locking cylinder is fixedly installed at the top position of the main seat body.

[0015] Preferably, the locking claw comprises a horizontal claw body, and a rectangular opening is formed on the horizontal claw body;

[0016] The fixed sliding column passes through the rectangular opening;

[0017] An L-shaped pressing claw portion is integrally formed on the inner end of the horizontal claw body.

[0018] Preferably, rectangular rolling wheel grooves are respectively provided on both sides of the top of the horizontal claw body, and the rolling wheel rolls in the rectangular rolling wheel grooves.

[0019] Preferably, a spring telescopic plate assembly located at the lower end of the locking claw is sleeved on the fixed sliding column.

[0020] Preferably, the spring telescopic plate assembly includes a lifting plate slidably connected to a fixed slide column, and the spring telescopic plate assembly also includes a spring sleeved on the fixed slide column, and the two ends of the spring are respectively fixedly connected to the bottom of the lifting plate and the slide groove structure.

[0021] Preferably, a material carrier assembly is installed on the top of the clamp base.

[0022] Preferably, the material carrier assembly comprises a slide column slidably connected to the center position of the top of the clamp base, and the top of the slide column is fixedly connected to the material carrier;

[0023] The top of the loading seat is fixedly connected to a limiting column;

[0024] A main spring is sleeved on the sliding column.

[0025] Preferably, a cylinder base frame is installed at the bottom of the cylinder of the horizontal pushing cylinder, and the cylinder base frame is fixedly installed on the slide groove structure.

[0026] The utility model has the following beneficial effects:

[0027] 1. During the working process, when the water pump housing is loaded, all horizontal push cylinders work synchronously, pushing the driving slide inward to the locking cylinder, and the locking claw structure moves toward the center position of the tooling. Then, driven by the locking cylinder, the locking claw descends to the L-shaped pressing claw part and presses on the housing.

[0028] With the cooperation of four housing locking mechanisms, the housing with a high degree of irregularity can be fully locked from four different directions, thereby increasing the stability of the water pump housing (the water pump housing is a universal pump housing for automobile water pumps) during subsequent processing.

[0029] 2. At the same time, the roller is always limited and rolling in the rectangular roller groove 212, which not only plays a guiding role, but also keeps the locking claw horizontal and does not tilt, so that it moves horizontally close to the shell workpiece. Therefore, the pushing accuracy of the locking structure is greatly improved.

[0030] 3. When the locking claw is pushed and moved, the two rollers roll above the top of the locking claw. The locking claw is guided by the rollers, which increases the accuracy of the horizontal movement of the locking claw. Furthermore, during the horizontal pushing process, the locking claw and the pump body are always aligned, solving the problem of the existing cylinder-driven locking method, which has low locking accuracy and poor locking stability.

[0041] Example 1

[0042] like Figure 1-5As shown, a low-noise automobile engine water pump clamp includes a clamp base 1 (the transverse cross-section is circular and is fixedly mounted on a workbench such as a lathe in the same manner as in the prior art). The top of the clamp base 1 is provided with four slide groove structures 11 distributed in a circular array, and the slide groove structures 11 are respectively equipped with shell locking mechanisms connected to the locking water pump shell.

[0043] The specific structure of the housing locking mechanism is as follows:

[0044] The shell locking mechanism includes a driving slide 24 that is slidably connected to the slide groove structure 11. The driving slide 24 adopts a limited sliding method. Specifically, the slide groove structure 11 includes a main groove portion, and the two sides of the main groove portion are integrally formed with limited groove portions 111; correspondingly, the driving slide 24 includes a main seat body portion that is slidably connected to the main groove portion, and the two sides of the main seat body portion are integrally formed with limited portions 241 that slide in the limited groove portion 111.

[0045] At the same time, the top of the driving slide 24 is fixedly assembled and connected with a locking cylinder 23 (the locking cylinder 23 is fixedly installed at the top position of the main seat body), and the piston rod of the locking cylinder 23 is installed with a locking claw 21; the shape of the locking claw 21 is: the locking claw 21 includes a horizontal claw body, and a rectangular opening is opened on the horizontal claw body; the inner end of the horizontal claw body is integrally formed with an L-shaped pressing claw part 22.

[0046] At the same time, the housing locking mechanism also includes a horizontal pushing cylinder 25 that pushes the driving slide 24 to move. During the pushing process, the roller rolls against the locking claw 21. Specifically, a cylinder base is installed at the bottom of the cylinder of the horizontal pushing cylinder 25, and the cylinder base is fixedly installed on the slide structure 11.

[0047] During operation, when the water pump housing is loaded, all horizontal pushing cylinders 25 work synchronously, pushing the driving slide 24 inward to the locking cylinder 23, and the locking claw 21 structure moves toward the center position of the tooling. Then, driven by the locking cylinder 23, the locking claw 21 descends to the L-shaped pressing claw part 22 and presses on the housing.

[0048] With the cooperation of four housing locking mechanisms, the housing with a high degree of irregularity can be fully locked from four different directions, thereby increasing the stability of the water pump housing (the water pump housing is a universal pump housing for automobile water pumps) during subsequent processing.

[0049] Example 2

[0050] like Figure 1-5As shown, based on the structure of Example 1, in order to increase the stability and accuracy of the horizontal pushing cylinder 25 pushing the shell locking mechanism to lock the workpiece shell, the above-mentioned shell locking mechanism also includes a roller pulley assembly rollingly arranged on the locking claw 21, and the roller pulley assembly includes a plurality of roller pulleys 41 rolling on the top position of the locking claw 21, and the roller pulley 41 is installed with a wheel frame 42, and the wheel frame 42 is fixedly connected to a fixed slide post 43 fixedly installed in the slide groove structure 11 (the fixed slide post 43 passes through the rectangular opening 211); the fixed slide post 43 is located at the inner end of the main groove, and when it is pushed to move to a position close to the fixed slide post 43 in the shell locking mechanism, the locking claw 21 has extended above the center of the tooling and is located above the edge of the shell.

[0051] Specifically, rectangular rolling wheel grooves 212 are respectively opened on both sides of the top of the horizontal claw body, and the rolling pulley 41 rolls in the rectangular rolling wheel grooves 212 .

[0052] During operation, when the locking pawl 21 is pushed and moved, the two rollers 41 are limited and rolled above the top of the locking pawl 21. The limited rolling and guidance of the rollers 41 increase the precision of the horizontal movement of the locking pawl 21. Furthermore, during the horizontal pushing process, the locking pawl 21 and the pump body are always aligned, resolving the shortcomings of the prior art cylinder-driven locking method, which suffers from low locking precision and resulting low locking stability. Specifically, because the rollers 41 are always limited and rolled in the rectangular roller grooves 212, they not only serve as guides but also help maintain the horizontal movement of the locking pawl 21 in a horizontal, non-tilted manner close to the housing workpiece. Therefore, the pushing precision of the locking mechanism is greatly improved.

[0053] A spring-type expansion plate assembly is sleeved onto the fixed post 43 and is located below the locking pawl 21. The spring-type expansion plate assembly includes a lifting plate 44 slidably connected to the fixed post 43 (the width of the lifting plate 44 is greater than the width of the locking pawl 21). The spring-type expansion plate assembly also includes a spring 45 sleeved onto the fixed post 43. The ends of the spring 45 are fixedly connected to the bottom of the lifting plate 44 and the chute structure 11, respectively.

[0054] When the locking claw 21 is driven to the inner side of the slide groove structure 11, the cylinder drives the locking claw 21 to move downward until it contacts and presses the lifting plate 44, and continues to press the lifting plate 44 downward. After the spring 45 is compressed to the limit, the inner end of the locking claw 21 (the L-shaped pressing claw portion 22) contacts and presses the housing.

[0055] After the processing is completed, with the cooperation of the lifting plate 44 and the spring 45, the locking claw 21 is pushed up until the locking claw 21 quickly releases the housing.

[0056] Example 3

[0057] like Figure 1-5 As shown, this embodiment builds upon the structure of Example 2, with a loading base assembly mounted on the top of the fixture base 1. Specifically, similar to existing housing loading structures, the loading base assembly includes a slide post 321 slidably connected to the center of the top of the fixture base 1 (a matching slot is provided in the center of the top of the fixture base 1). The top of the slide post 321 is fixedly connected to the loading base 3; the top of the loading base 3 is fixedly connected to a limit post 31; and a main spring 32 is sleeved on the slide post 321. After loading, the central mechanical hole in the water pump housing (the hole structure in the water pump housing blank, specifically at the impeller position) is aligned with the limit post 31. The water pump housing is now supported on the loading base 3. As the locking claw 21 is pressed down and locked, the slide post 321 fixed to the loading base 3 descends and retracts into the fixture base 1, compressing the main spring 32. This process provides a buffering protection for the housing (mostly made of stamped alloy material), preventing deformation caused by excessive pressure from the locking claw 21.

[0058] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
