Description

Technical Field

[0001] This utility model belongs to the field of tooling technology for automobile engine production, and in particular relates to an auxiliary installation tool for automobile engine belts. Background Technology

[0002] The distance between the multiple pulleys of a car engine is greater than the original length of the elastic belt; this means that when installing the elastic belt onto the multiple pulleys of the engine, a metal rod is needed to hold the top of one pulley and pry the elastic belt in.

[0003] Because the elastic belt has a high tension, the belt tension of a typical engine will reach 500N after installation. Therefore, using a metal bar to pry it in is not only inefficient, but also easily damages the belt and the wedge top of the pulley. This damage is generally irreversible and will render the pulley or belt unusable. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an auxiliary installation tool for automobile engine belts, which solves the problem that the existing method of using a metal bar to pry the belt into the engine pulley system is prone to damage to the belt and the wedge top of the pulley.

[0005] To achieve the above and other related objectives, this utility model provides an auxiliary installation tool for an automotive engine belt, used to install the belt onto an automotive engine pulley system. The pulley of the automotive engine pulley system has weight-reducing holes.

[0006] The central disc is equipped with a force-bearing component;

[0007] The positioning plate has its inner side fixed to the central plate and its outer side fixed with a retaining edge.

[0008] The bottom surface of the positioning disk is provided with a plurality of positioning posts, and the positioning posts are provided with grooves.

[0009] When the auxiliary installation tool is installed on the pulley, each of the plurality of positioning pins is inserted into one of the weight reduction holes;

[0010] When a rotational force is applied to the force-bearing part, the central disk rotates together with the positioning disk; after the inner wall of the groove and the inner wall of the weight-reducing hole abut against each other, the pulley and the central disk rotate together, and the retaining edge presses the belt into the groove of the pulley.

[0011] Optionally, the positioning disk is fan-shaped, with the inner side being the short side and the outer side being the long side.

[0012] Optionally, the retaining edge is trapezoidal in shape, descending from high to low in a clockwise direction.

[0013] Optionally, the force-bearing part is a hexagonal bolt head fixed to the center of the outer surface of the central disk.

[0014] Optionally, a clearance groove is provided on the inner surface of the positioning disk.

[0015] Optionally, there are two positioning posts, which are arranged at intervals relative to the position of the weight reduction holes.

[0016] As described above, the auxiliary installation tool for automobile engine belts of this utility model has at least the following beneficial effects:

[0017] This auxiliary installation tool for automotive engine belts uses a positioning disc with a fixed stop edge on the outer side. Multiple positioning pins with grooves are located on the bottom surface. During use, the operator first places the belt onto the engine pulley system. At one pulley, the belt may not be fully installed. The positioning pins are then inserted into the weight-reducing holes of that pulley, allowing the stop edge to abut against the outer side of the belt. A rotational force is applied to the load-bearing part of the central disc. Initially, the auxiliary installation tool rotates independently for a very short time. However, when the inner wall of the positioning pin groove abuts against the inner wall of the weight-reducing hole, a self-locking mechanism is formed, meaning the auxiliary installation tool and the pulley become a single unit and rotate together. The stop edge also rotates, applying a pushing force to the belt, pressing it into the pulley's groove. This avoids the damage to the belt and pulley wedges that can occur with prying the belt in using a metal rod. It is also convenient to operate and improves work efficiency.

[0027] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0028] Please see Figures 1 to 5 It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0029] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0030] Please see Figure 1 This utility model provides an auxiliary installation tool 1 for an automotive engine belt, used to install the belt 22 onto an automotive engine pulley system 2. The pulley 21 of the automotive engine pulley system 2 has a weight-reducing hole 212. The design feature of this auxiliary installation tool 1 is that it includes:

[0031] like Figure 1 and Figure 2 The central disk 11 shown is provided with a force-bearing part 111.

[0032] like Figures 1 to 3 The positioning disk 12 shown has its inner side fixed to the central disk 11 and its outer side fixed to a retaining edge 121; the bottom surface of the positioning disk 12 is provided with a plurality of positioning posts 122, and the positioning posts 122 are provided with grooves 123.

[0033] like Figure 1 and Figure 2As shown, when using this auxiliary installation tool 1, the operator first puts the belt 22 onto the engine pulley system 2. The belt 22 cannot be installed in place on one of the pulleys 21. At this time, multiple positioning pins 122 are inserted into the weight reduction holes 212 of the pulley 21 respectively, so that the flange 121 and the outer side of the belt 22 abut against each other, and a rotational force is applied to the force-bearing part 111 of the central disc 11.

[0034] like Figure 2 and Figure 4 As shown, at the beginning, this auxiliary installation tool 1 will rotate independently.

[0035] like Figure 1 , Figure 3 and Figure 5 As shown, when the inner wall of the groove 123 of the positioning post 122 abuts against the inner wall of the weight reduction hole 212, a self-locking mechanism is formed, that is, the auxiliary installation tool 1 and the pulley 21 form a whole and rotate together; the flange 121 also rotates accordingly and applies a pushing force to the belt 22, pushing the belt 22 into the groove 211 of the pulley 21; this avoids the problem that the method of prying the belt 22 in with a metal rod can easily damage the belt 22 and the wedge top of the pulley 21; at the same time, it is convenient to operate and improves work efficiency.

[0036] In another implementation, please refer to Figure 2 and Figure 3 The positioning disc 12 is fan-shaped, with a short inner side and a long outer side, which is compatible with the shape of the pulley 21 and is easy to use.

[0037] In another implementation, please refer to Figure 2 and Figure 3 The retaining edge 121 is trapezoidal in shape, descending from high to low in a clockwise direction. It can not only push the belt 22 into the groove 211 of the pulley 21, but also avoid interference between the retaining edge 121 and the pulley 21, while saving materials.

[0038] In another implementation, please refer to Figure 1 and Figure 2 The force-bearing part 111 is a hexagonal bolt head fixed to the center of the outer surface of the central disc 11. The tool for applying external force can be a common wrench 3, which is easy to use with existing tools and facilitates operation.

[0039] In another implementation, please refer to Figure 3 and Figure 5 The positioning plate 12 has a clearance groove 124 on its inner surface to reduce the possibility of interference between the auxiliary installation tool 1 and the pulley 21.

[0040] In other implementations, such as Figure 3 and Figure 5As shown, there are two positioning posts 122, which are arranged at intervals relative to the position of the weight reduction hole 212. The two positioning posts 122 can complete the positioning and lock the auxiliary installation tool 1 and the pulley 21. At the same time, they are equivalent to three or more positioning posts 122, which is convenient for processing.

[0041] In summary, this utility model utilizes a structure where the outer edge of the positioning disc 12 is fixed to the retaining edge 121, and multiple positioning posts 122 are provided on the bottom surface. Each positioning post 122 has a groove 123. During use, the operator first mounts the belt 22 onto the engine pulley system 2. However, the belt 22 cannot be fully installed on one of the pulleys 21. At this point, the multiple positioning posts 122 are inserted into the weight-reducing holes 212 of the pulley 21, causing the retaining edge 121 to abut against the outer edge of the belt 22, applying rotational force to the force-bearing portion 111 of the central disc 11. In a short period of time, the auxiliary installation tool 1 will rotate independently. However, when the inner wall of the groove 123 of the positioning post 122 abuts against the inner wall of the weight reduction hole 212, a self-locking mechanism is formed, meaning that the auxiliary installation tool 1 and the pulley 21 form a single unit and rotate together. The retaining edge 121 also rotates accordingly, applying a pushing force to the belt 22, pressing the belt 22 into the groove 211 of the pulley 21. This avoids the problem of damage to the belt 22 and the wedge top of the pulley 21 that can easily occur when using a metal rod to pry the belt 22 in. Furthermore, it is convenient to operate and improves work efficiency. Therefore, this utility model effectively overcomes the shortcomings of the prior art and has high industrial application value.

[0042] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
