Description
Technical Field
[0001] This utility model relates to the field of automotive repair tools, specifically to an engine steel sleeve pressing device. Background Technology
[0002] In engine repair, the installation of engine bushings is a crucial step, directly affecting the engine's sealing, durability, and overall performance. Traditional methods for installing engine bushings typically involve hammering, where the bushing is manually or with a hammer to force it into a pre-set groove. However, this method has many drawbacks. It is not only cumbersome and inefficient, but also highly prone to damaging the bushing. Specifically, the hammering method makes it difficult to precisely control the force and striking position during installation, often resulting in scratches, deformation, or even cracks on the bushing surface. This damage severely impacts the bushing's sealing performance and lifespan. Furthermore, the impact force from hammering can potentially damage other engine components, increasing repair costs and complexity. This method also demands high operator skill and poses significant safety hazards; operational errors could lead to serious production accidents. With the rapid development of the automotive industry and continuous advancements in engine technology, the demands for precision and efficiency in engine repair are constantly increasing. Traditional hammering installation methods can no longer meet the needs of modern engine repair, and there is an urgent need for a more scientific, efficient and safe steel sleeve installation tool to replace the traditional manual hammering method.
[0003] Therefore, to address the aforementioned problems in the existing technology, this utility model proposes an engine steel sleeve pressing device, aiming to achieve safe, efficient, and non-destructive installation of the steel sleeve through the design of a specialized tool. This device, through its ingenious mechanical structure design, can precisely control the pressing force and direction, and by utilizing the lever principle, achieves labor-saving results while avoiding damage to the steel sleeve, thus improving installation efficiency and operational safety, and bringing significant technological advancements to the field of engine maintenance. Utility Model Content
[0004] The purpose of this utility model is to provide an engine steel sleeve pressing device to address the above-mentioned problems. This device enables safe, efficient, and non-destructive installation of the steel sleeve, and allows for precise control of the pressing force and direction to avoid damage to the steel sleeve.
[0005] The technical solution of this utility model is as follows:
[0006] This utility model discloses an engine steel sleeve pressing device, comprising a fixing device and a pressing device. The fixing device has fixing rods at both ends, and a vertical rod between the two fixing rods. Rotary shaft holes are evenly distributed on the vertical rod. The pressing device includes a force-bearing rod, a rotating part at the lower part of the force-bearing rod, and a pressing part perpendicular to the force-bearing rod at the lower part of the force-bearing rod. The diameter of the force-bearing rod is larger than the diameter of the vertical rod. A rotating shaft is provided in the rotating shaft holes.
[0007] Specifically, the pivot is a bolt, the length of the pivot is more than three times the diameter of the upright, the pivot is fitted with a pivot hole, and the pivot is screwed into the pivot hole, leaving the same portion on both sides of the upright.
[0008] Furthermore, the rotating part consists of two cylindrical rods, symmetrically arranged on both sides of the force-bearing rod. During operation, the rotating part is fitted onto the upright rod and placed on the rotating shaft.
[0009] Furthermore, the pressing part is located between the rotating parts and is perpendicular to the surface formed by the two cylindrical rods of the rotating part.
[0010] Furthermore, a pressing block is provided on the outer side of the pressing part. This feature allows the pressing block to have a larger force-bearing area when applying pressure to the engine steel sleeve, thereby reducing the pressure and lowering the risk of damaging the engine steel sleeve.
[0011] Furthermore, both the fixing device and the pressing device are made of stainless steel, and the components of the fixing device and the pressing device are connected by welding. The use of stainless steel can ensure the strength of each component and prevent the components from separating due to stress.
[0012] The following is a second embodiment, in which a circular rotating groove is provided on the cylindrical rod of the pressing part. After the rotating part is fitted onto the upright rod, the rotating shaft on the upright rod is inserted into the rotating groove.
[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0014] 1. This utility model provides an engine steel sleeve pressing device that, through ingenious mechanical structure design, can precisely control the pressing force and direction, and by utilizing the lever principle, achieves the purpose of saving effort while avoiding damage to the steel sleeve.

[0023] This utility model discloses an engine steel sleeve pressing device, comprising a fixing device 1 and a pressing device 2. The fixing device 1 has fixing rods 11 at both ends, and a vertical rod 12 is located between the two fixing rods 11. Rotating shaft holes 13 are evenly distributed on the vertical rod 12. The pressing device 2 includes a force-bearing rod 21, a rotating part 22 is provided at the lower part of the force-bearing rod 21, and a pressing part 23 perpendicular to the force-bearing rod 21 is also provided at the lower part of the force-bearing rod 21. The diameter of the force-bearing rod 21 is larger than the diameter of the vertical rod 12. A rotating shaft 3 is provided in the rotating shaft hole 13.
[0024] The features and performance of this utility model will be further described in detail below with reference to the embodiments.
[0025] like Figures 1-4As shown, this is the first embodiment of the present invention. During operation, firstly, according to the required pressing height of the steel sleeve, the rotating shaft 3 is screwed into the rotating shaft hole 13 of the required height. The rotating shaft 3 leaves the same length on both sides of the upright 12. Then, the fixing rod 11 of the fixing device 1 is inserted into the fixing hole 53 on the steel sleeve frame 5. Afterwards, the pressing device 2 is fitted onto the upright and pushed to the innermost position. The two cylindrical rods of the rotating part 22 are respectively placed on the rotating shaft 3 left on both sides of the upright 12. At this time, the operator holds the force-bearing rod 2. 1. Slowly lower the pressing device 2 until the lower plane of the pressing part 23 is parallel to the upper plane of the steel sleeve 51, making uniform contact, and the force of the pressing part 23 on the steel sleeve 51 is vertically downward. If the lower surface of the pressing part 23 is not basically parallel to the upper plane of the steel sleeve 51, the angle of the lower surface of the pressing part 23 can be adjusted by adjusting the height of the rotating shaft 3. If the force cannot be uniform and vertically downward, the steel sleeve 51 may be deformed. At the same time, the welding position of the pressing part 23 is determined by the position from the fixing hole 53 to the steel sleeve groove 52. At this time, this utility model forms a lever, the contact point of the rotating shaft 3 of the pressing device 2 is the fulcrum, the distance from the rotating shaft 3 to the pressing part 23 is the resistance arm, and the position of the rotating shaft 3 and the force point on the force rod 21 is the effort arm. The effort arm is longer than the resistance arm, achieving the effect of saving effort.
[0026] Generally, at least three engine steel sleeve pressing devices of this invention are set in the same steel sleeve groove 52, one at approximately 120° intervals, to ensure that the steel sleeve 51 is subjected to uniform force. During operation, after the steel sleeve 51 is pressed into the steel sleeve groove 52 to a certain height, the height of the rotating shaft 3 needs to be adjusted to ensure that the angle below the pressing part 23 is basically parallel at all times.
[0027] like Figure 5 As shown, in the second embodiment of this utility model, a circular rotating groove 4 is provided on the cylindrical rod of the pressing part 23. After the rotating part 22 is sleeved on the upright rod 12, the rotating shaft 3 on the upright rod is inserted into the rotating groove 4. Before the rotating groove is provided, the pressing device 2 needs to be pushed towards the fixing device 1 manually to ensure that the pressing device 2 will not slip off the fixing device 1. After the circular rotating groove 4 is provided, the rotating part 22 can be rotatably fixed on the rotating shaft 3, thus achieving the effect of saving effort.
[0028] The embodiments described above merely illustrate specific implementation methods of this application, and while the descriptions are detailed and specific, they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the technical solution of this application, and these modifications and improvements all fall within the scope of protection of this application.
