Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a lubricating oil application fixture, particularly a horizontal water pump bracket lubricating oil application fixture. Background Technology

[0002] A horizontal water pump refers to a type of pump with its pump shaft arranged horizontally. A horizontal water pump generally includes a pump casing and a support fixed horizontally to the rear side of the pump casing. The support is cylindrical and is used to support the pump shaft extending from the pump casing.

[0003] There is a certain water pump bracket, such as Figure 1 As shown, the overall shape is cylindrical, with both ends of the water pump bracket 1 tapered to form the upper bearing section and the lower bearing section 1a, respectively. During installation, bearings are press-fitted into both the upper bearing section 1a and the lower bearing section to rotate and support the pump shaft.

[0004] When pressing bearings, a layer of lubricating oil is first applied to the inner walls of both the upper and lower bearing sections. Currently, when applying lubricating oil, the bracket is usually positioned on a specific fixture first, then the oil is applied. After the oil is applied, the bracket is removed from the fixture and sent into the pressing equipment. The whole process involves many steps and is quite cumbersome. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a convenient assembly tooling for applying lubricating oil to a horizontal water pump bracket.

[0006] The purpose of this utility model can be achieved through the following technical solution: a horizontal water pump bracket lubrication tooling, including a base and a rotating shaft vertically arranged on the base, characterized in that a rocker arm is horizontally rotatably arranged on the rotating shaft, and both ends of the rocker arm have horizontally arranged arc seats, and the two arc seats are centrally symmetrically arranged along the axis of the rotating shaft; the ratio of the arc length of the arc seat to the circumference of the whole circle it is located is greater than 1 / 2, and the lower bearing part of the water pump bracket extends into the arc seat through an opening provided on one side of the arc seat, the inner hole of the arc seat is a tapered hole with a diameter that gradually decreases from top to bottom, and the lower end outer wall of the water pump bracket has a tapered surface that matches the tapered hole, the tapered surface is above the lower bearing part, and the tapered surface can be tightly attached to the wall of the tapered hole.

[0007] In use, the water pump bracket extends into the arc seat using the lower bearing section. Then, the water pump bracket moves down so that the conical surface fits against the wall of the conical hole, thus supporting the water pump bracket upwards. The two arc seats are respectively positioned at the lubrication oil application station and the bearing pressing station. By rotating the rocker arm, the two water pump brackets can switch back and forth between the lubrication oil application station and the bearing pressing station. This allows the water pump bracket to perform the two processes of pressing in the bearing and applying lubricating oil after only one positioning, effectively reducing the number of operation steps and facilitating the overall assembly of the water pump.

[0008] In the above-mentioned horizontal water pump bracket lubrication tooling, the rocker arm includes an arm body and a tube body vertically formed in the middle of the arm body. Two arc seats are respectively set at both ends of the arm body. The tube body is sleeved on the outside of the rotating shaft, and the base is also provided with a limiting component for supporting the tube body upward.

[0009] In the above-mentioned horizontal water pump bracket lubrication fixture, the limiting component can slide up and down and lock in the sliding position, so as to adjust the position of the straight pipe body by sliding the limiting component up and down, thereby adjusting the height of the arc seat. This not only facilitates debugging, but also better adapts to water pump brackets of different sizes, making it widely applicable.

[0010] In the aforementioned horizontal water pump support lubrication fixture, a guide rod is vertically fixed on the base, and an arc sleeve is fitted over the guide rod. A pressure plate is vertically mounted on one side of the arc sleeve, and both ends of the arc sleeve are detachably fixed to the pressure plate by horizontally mounted screws. A clamping opening for clamping the guide rod is formed between the pressure plate and the arc sleeve. The limiting component is a baffle plate formed on the other side of the arc sleeve, and the bottom wall of the straight pipe body abuts against the baffle plate. The movement or locking of the limiting component can be controlled by tightening or loosening the screws, which has the advantages of simple structure and convenient use.

[0011] In the above-mentioned horizontal water pump support lubrication tooling, the side of the baffle near the straight pipe body is formed with a limiting step that matches the lower end of the straight pipe body. The limiting step is composed of a vertically set step side and a step bottom, and the step side and the step bottom respectively press against the outer side and bottom surface of the lower end of the straight pipe body to make the rotation of the straight pipe body more stable.

[0012] As an alternative, in the aforementioned horizontal water pump bracket lubrication fixture, the limiting component is a limiting ring screwed onto the rotating shaft, and the bottom wall of the straight pipe body presses against the limiting ring.

[0013] In the aforementioned horizontal water pump bracket lubrication fixture, when the rocker arm is swung, both ends of the arm can contact and limit the movement with the outer wall of the guide rod, so that the two arc seats can be moved into place at once, making it convenient to use.

[0014] Compared with existing technologies, this horizontal water pump support lubrication tooling has the following advantages:

[0015] 1. By rotating the rocker arm, the two water pump brackets can be switched back and forth between the lubrication oil application station and the bearing pressing station. This allows the water pump brackets to be positioned once before the bearing pressing and lubrication oil application processes can be carried out, effectively reducing the number of operation steps and facilitating the overall assembly of the water pump.

[0016] 2. The position of the straight pipe body can be adjusted by sliding the limiting component up and down, thereby adjusting the height of the arc seat. This not only facilitates debugging, but also better adapts to water pump brackets of different sizes, making it widely applicable. Attached Figure Description

[0021] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0022] Example 1: As Figure 1 As shown, in this horizontal water pump support lubrication fixture, the water pump support 1 is a cylindrical structure, with both the upper and lower ends of the water pump support 1 tapering, and the upper and lower ends of the water pump support 1 are the upper bearing part and the lower bearing part 1a, respectively.

[0023] This horizontal water pump bracket 1 lubrication tooling includes a base 2 and a rotating shaft 3 vertically mounted on the base 2.

[0024] in,

[0025] A rocker arm 4 is horizontally rotatable on the rotating shaft 3. Both ends of the rocker arm 4 have horizontally arranged arc-shaped seats 4a, meaning that one side of each arc-shaped seat 4a has an opening. The axis of the arc-shaped seats 4a is vertical, and the two arc-shaped seats 4a are centrally symmetrical about the axis of the rotating shaft 3. The ratio of the arc length of the arc-shaped seat 4a to the circumference of the circle it belongs to is greater than 1 / 2, and preferably, the ratio is 0.6.

[0026] like Figure 2 As shown, the upper bearing portion of the water pump bracket 1 extends into the arc seat 4a through the opening. The inner hole of the arc seat 4a is a tapered hole with a diameter that gradually decreases from top to bottom. The lower outer wall of the water pump bracket 1 has a tapered surface 1b that matches the tapered hole, and the tapered surface 1b can fit tightly against the wall of the tapered hole.

[0027] In use, the water pump bracket 1 extends into the arc seat 4a using the lower bearing part 1a. Then, the water pump bracket 1 moves down so that the conical surface 1b is attached to the wall of the conical hole to support the water pump bracket 1 upward. The two arc seats 4a are respectively in the lubrication oil application position and the bearing pressing position. By rotating the rocker arm 4, the two water pump brackets 1 can switch back and forth between the lubrication oil application position and the bearing pressing position. This allows the water pump bracket 1 to perform the two processes of pressing the bearing and applying lubricating oil after one positioning, effectively reducing the number of operation steps and facilitating the overall assembly of the water pump.

[0028] In this embodiment,

[0029] The rocker arm 4 is a one-piece structure, comprising an arm body 4b and a vertically formed tube 4c in the middle of the arm body 4b. Two arc-shaped seats 4a are respectively located at both ends of the arm body 4b. The tube 4c is sleeved around the rotating shaft 3, with the inner wall of the tube 4c and the outer wall of the rotating shaft 3 in circumferential contact. The base 2 also has a limiting member 5 for upward support of the tube 4c. In the actual product, the rocker arm 4 is made of metal and is a cast one-piece component.

[0030] To further explain, the limiting member 5 can slide up and down and lock in the sliding position, so that the position of the straight pipe body 4c can be adjusted by sliding the limiting member 5 up and down, thereby adjusting the height of the arc seat 4a. This not only facilitates debugging, but also better adapts to water pump brackets 1 of different sizes, making it widely applicable.

[0031] The specific structure of the limiting component 5 is as follows: a guide rod 6 is vertically fixed on the base 2, and an arc sleeve 7 is fitted over the guide rod 6; a pressure plate 8 is vertically provided on one side of the arc sleeve 7, and both ends of the arc sleeve 7 are detachably fixed to the pressure plate 8 by horizontally arranged screws, and a clamping port 9 for clamping the guide rod 6 is formed between the pressure plate 8 and the arc sleeve 7, that is, after the screws are tightened, the two sides of the guide rod 6 are respectively pressed against the inner wall of the arc sleeve 7 and the pressure plate 8; the limiting component 5 is a baffle formed on the other side of the arc sleeve 7, and the bottom wall of the straight tube body 4c abuts against the baffle. The movement or locking of the limiting component 5 can be controlled by tightening or loosening the screws, which has the advantages of simple structure and convenient use. Further explanation is provided below. Figure 2 and Figure 3 As shown, the side of the baffle near the straight tube 4c is formed with a limiting step 5a that matches the lower end of the straight tube 4c. The limiting step 5a is composed of a vertically arranged step side and a step bottom, and the step side and the step bottom respectively press against the outer side and bottom of the lower end of the straight tube 4c to make the rotation of the straight tube 4c more stable.

[0032] In the actual product, when the rocker arm 4 is swung, both ends of the arm body 4b can contact and limit the outer wall of the guide rod 6 respectively, so that the two arc seats 4a can move into place at one time, which is convenient for use.

[0033] Example 2: The structure and principle of Example 2 are basically the same as those of Example 1. The difference is that the limiting member 5 is a limiting ring screwed onto the rotating shaft 3, and the bottom wall of the straight tube 4c presses against the limiting ring.

[0034] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
