Description

Technical Field

[0001] This utility model relates to the field of oil pump installation technology, specifically a quick removal device for a steering oil pump pin. Background Technology

[0002] During the research and testing of the power steering pump, it is necessary to frequently remove the outlet pin insert.

[0003] Normally, a tap is used to machine the internal thread of the pin, and then a traditional pin puller is used to connect the internal thread and pull out the hollow pin. However, due to the installation requirements and design of the power steering pump, the outlet pin has a certain degree of adhesion, making it difficult to remove the outlet pin, which slows down the removal efficiency of the outlet pin.

[0004] Therefore, we propose a quick-release device for the steering pump pin, which facilitates the rapid removal of the steering pump pin. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a quick removal device for the pin of a steering pump to solve the problems existing in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick removal device for a steering oil pump pin, comprising a slide rod, a slider slidably nested on the outer wall of the slide rod, a detachable threaded head at one end of the slide rod, and a pin nested and fixed at the other end of the slide rod.

[0007] Furthermore: a through hole is provided on the outer wall of the pin, and a stop bar is inserted into the through hole of the pin.

[0008] Furthermore: the slider slides on the slide bar and strikes the stop bar.

[0009] Furthermore: the inner wall of the slider is provided with balls arranged in a straight line at equal intervals, and the outer wall of the slide rod is provided with a groove for accommodating the balls, and the balls of the slider slide linearly in line with the groove of the slide rod.

[0010] Furthermore, a countersunk groove is provided on the right side of the slider, and a spring for cushioning is fixed in the countersunk groove.

[0011] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0012] 1) The quick-release device for the steering oil pump pin of this utility model does not require tapping. The threaded head is self-tapping into the inner hole. During the pin removal process, the slider moves to the right, and the hollow pin is continuously vibrated, causing the hollow pin to fall off automatically, thus increasing the speed of pin removal.

[0013] 2) The quick-release device for the steering pump pin of this utility model allows for quick replacement of the threaded head to meet the needs of pins with different hole diameters; the pin removal device can be reused, reducing costs.

[0014] 3) In the quick removal device for the steering oil pump of this utility model, in order to ensure that the movement trajectory of the slider is linear when the slider extends the sliding rod, the ball inside the slider moves along the groove of the sliding rod, so as to avoid insufficient removal force caused by the rotational movement of the slider during the removal action.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The structures involved in this utility model are not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example:

[0022] Please see Figure 1-4 This utility model provides a technical solution: a quick removal device for a steering oil pump pin, including a slide rod 3, a slider 2 slidably nested on the outer wall of the slide rod 3, the slider 2 sliding left and right on the slide rod 3, one end of the slide rod 3 is provided with a detachable threaded head 1, the threaded head 1 is replaceable and can be replaced according to the actual size of the oil pump pin 5, and the other end of the slide rod 3 is nested and fixed with a pin 5.

[0023] The pin 5 has a through hole on its outer wall, and a stop bar 4 is inserted into the through hole of the pin 5 to block the movement range of the slider 2.

[0024] The slider 2 slides on the slide bar 3 and strikes the stop bar 4, thereby removing the steering oil pump pin 5 shaft by striking it.

[0025] The inner wall of the slider 2 is provided with balls 7 arranged in a straight line at equal intervals, and the outer wall of the slide rod 3 is provided with a groove 6 for accommodating the balls 7. The balls 7 of the slider 2 slide linearly in line with the groove 6 of the slide rod 3. When the slider 2 slides and nests on the outer wall of the slide rod 3, the balls 7 inside the slider 2 move along the groove 6 of the slide rod 3, thereby restricting the movement trajectory of the slider 2.

[0026] The slider 2 has a countersunk groove on its right side, and a spring 8 for buffering is fixed in the countersunk groove. The spring 8 buffers the impact of the slider 2 and prevents the slider 2 from hitting people with excessive force at the end.

[0027] The working principle of this utility model embodiment is as follows: the through hole of the corresponding pin 5 of the stop lever is passed through, the threaded head 1 and the slide bar 3 are fixed, and after the threaded head 1 is threadedly connected to the steering oil pump by the pin 5 shaft, the slide bar 2 moves to the right, the hollow pin 5 shaft is continuously vibrated, and the hollow pin 5 shaft automatically falls off.

[0028] When the slider 2 slides and nests on the outer wall of the slide rod 3, the ball bearing 7 inside the slider 2 moves along the groove 6 of the slide rod 3.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
