Description

Technical Field

[0001] The present disclosure generally relates to the technical field of mechanical manufacturing, and in particular, to an auxiliary installation tool for mechanical parts, and more specifically, to an auxiliary installation tool for assisting the installation of mechanical parts that require an installation force to be applied in a predetermined direction. Background Art

[0002] In industrial production, the installation positions of some mechanical parts are difficult to access. For example, because they are blocked by other mechanical parts, even if the operator's hand can barely reach the gap between the mechanical parts and touch the installation position, it is difficult to apply enough force to complete the installation at this reluctant position. For example, in the process of installing the steering column of the vehicle to the steering spline of the front axle, the worker needs to bend over for a long time, which will cause waist injury. The ergonomic performance of this process is very poor. At the same time, additional assistants are required to help with force on the side to complete the installation, which increases the labor cost of production. In order to make the installation smoother, it is also necessary to apply lubricating liquid to the periphery of the steering column in advance, which wastes installation time and materials. The installation process is a link in the assembly line. If the time is too long, it will affect the production progress of the entire assembly line, thereby affecting the overall vehicle production time.

[0003] Therefore, in production practice, an auxiliary installation tool is needed to assist the operator to easily install the steering column onto the front axle steering spline, which can not only save additional auxiliary personnel, save process installation time, not affect the assembly line process, but also improve ergonomics and save lubricating materials. In addition, it is also hoped that the auxiliary installation tool has a simple structure, is easy to operate, and is not easy to damage. Utility Model Content

[0035] The utility model provides an auxiliary installation tool for assisting the installation of mechanical parts that require installation force to be applied in a predetermined direction. Figure 5 The mechanical part may be a steering column 3 of the vehicle, and the operator needs to apply a vertical downward installation force on the steering column 3 to install the steering column 3 onto the front axle steering spline 4.

[0036] The head of the auxiliary installation tool of the utility model can penetrate into the part that is difficult to reach or difficult to apply force manually, so as to apply a sufficiently large installation force with a predetermined direction to the mechanical parts to implement the installation (for example, applying a sufficiently large vertical downward installation force to clamp the steering column 3 onto the front axle steering spline 4). The auxiliary installation tool and its head have a simple structure, are easy to operate, and are not easy to be damaged. The auxiliary installation tool not only has a very low material cost, but also can greatly reduce labor costs and operating costs. The specific structure of the auxiliary installation tool of the utility model will be described in detail with reference to the accompanying drawings.

[0037] like Figure 1 and Figure 2 As shown, the auxiliary installation tool 1 may include a joint portion 11, a rod portion 12 and a handle portion 13. The joint portion 11 is located at one end of the rod portion 12, and the handle portion 13 is located at the other end of the rod portion 12 opposite to the joint portion 11.

[0038] In some embodiments, the engaging portion 11 may include an engaging surface 111 . The engaging surface 111 is configured to abut against a to-be-engaged surface of a mechanical part to be installed and transmit an installation force in a direction perpendicular to the engaging surface 111 .

[0039] In some embodiments, Figure 2 and Figure 4 As shown, the engagement surface 111 can be configured as a plane. In some embodiments, the engagement surface 111 can include a recess (not shown in the figure) that can accommodate the engagement surface of the mechanical part to be installed. In some embodiments, the engagement surface 111 can include a high friction coefficient material so that the engagement surface 111 is not easy to slide apart when engaging the mechanical part to be installed.

[0040] In some embodiments, Figure 1 As shown, the joint portion 11 may include two oppositely disposed joint surfaces 111, and the two joint surfaces 111 may be substantially parallel to each other. Figure 3 As shown, the distance between the two joint surfaces 111 gradually decreases along the extension direction of the two joint surfaces 111, so that the distance can be set to be larger at the root of the joint part and smaller at the tip of the joint part (in other words, the joint part is thicker at the root and thinner at the tip), so as to better match with the to-be-joined surface of the mechanical part or to facilitate easier insertion into the smaller space between the mechanical parts. In other embodiments, the joint part 11 can also have other different structures.

[0041] In some embodiments, the rod 12 can be configured as a cylindrical rod with a circular cross section. In other embodiments, the rod 12 can have a cross section of other shapes, such as a quadrilateral, pentagon, hexagon, octagon or other cross section.

[0042] In some embodiments, the rod 12 may include an escape area 121. When the operator engages the engagement surface 111 of the auxiliary installation tool 1 with the engagement surface of the mechanical part to be installed, some parts of the mechanical part to be installed (e.g., Figure 6 The portion 41 of the steering column 3 shown and / or other mechanical parts may block the entry of the engaging surface 111 of the auxiliary installation tool 1. To this end, an avoidance area 121 can be provided on the rod portion 12 to avoid the obstacle so that the engaging surface 111 of the auxiliary installation tool 1 can be abutted against the engaging surface of the mechanical part to be installed.

[0043] In some embodiments, Figure 7 As shown, the avoidance area 121 of the rod 12 may include a avoidance notch 123 facing the obstacle. The avoidance notch 123 is shaped to accommodate the obstacle when the engagement surface 111 of the auxiliary installation tool 1 engages with the engagement surface of the mechanical part to be installed.

[0044] In some embodiments, the avoidance area 121 of the rod 12 may include a reinforcing protrusion 122 disposed on the other side of the rod 12 opposite to the avoidance notch 123. The reinforcing protrusion 122 may increase the thickness of the support portion of the avoidance area to strengthen the strength of the avoidance area 121. In some embodiments, the protrusion shape of the reinforcing protrusion 122 and the concave shape of the avoidance notch 123 may be the same. In some embodiments, the thickness of the support portion of the rod 12 between the avoidance notch 123 and the reinforcing protrusion 122 may be no less than the thickness of the support portion of other sections of the rod 12 (for example, no less than the diameter of the cylindrical rod 12).

[0045] In some embodiments, the handle portion 13 may include an ergonomic curved surface (not shown) configured to accommodate the operator's palm or fingers, making it easier for the operator to apply force. The ergonomic curved surface may be provided on the same side of the auxiliary installation tool 1 as the engagement surface 111 .

[0046] In some embodiments, the size of the auxiliary installation tool 1 can be configured to more easily match the environment in which the mechanical parts are located and is suitable for applying a predetermined direction of installation force to the mechanical parts. For example, in order to more easily approach the steering column 3, the rod 12 of the auxiliary installation tool 1 can have a length between 150 and 200 mm, preferably a length of about 160 mm. In order to better avoid obstacles, the avoidance gap 123 of the auxiliary installation tool 1 can have a width between 20 and 30 mm and a depth between 5 and 10 mm, preferably a width of 25 mm and a depth of 5 mm. In order to better hold the auxiliary installation tool 1, the handle of the auxiliary installation tool 1 can have a length between 100 and 150 mm, preferably a length of 120 mm. In addition, the joint of the auxiliary installation tool 1 can have a length between 10 and 20 mm and a thickness between 5 and 10 mm, preferably a length of 15 mm and a thickness of 5 mm.

[0047] In some embodiments, Figure 3 and Figure 5 As shown, the auxiliary installation tool 1 may further include a support member 2. The support member 2 may be placed by the operator at a certain position between the operator and the mechanical part to be installed, so as to be able to serve as a force fulcrum for the auxiliary installation tool 1, so that the auxiliary installation tool 1 can apply a sufficiently large required installation force in a lever manner, thereby solving the problem of difficulty in applying force during manual operation.

[0048] In some embodiments, Figure 3 As shown, the support member 2 may include a top and a bottom, the top may be configured to support at least a portion of the rod 12, and the bottom may be configured to be supported on a base surface. In some embodiments, the top of the support member may have a recessed portion configured to receive at least a portion of the rod 12 of the auxiliary installation tool 1 to stably support the rod 12 of the auxiliary installation tool 1. In some embodiments, the bottom of the support member 2 may include a high friction coefficient material so that during the application of the installation force, the bottom of the support member 2 and the base surface on which the support member 2 is placed are not easy to slide.

[0049] In some embodiments, the auxiliary installation tool 1 may not include a support member. When in use, some components in the surrounding environment of the mechanical part can be used as force fulcrums so that the auxiliary installation tool 1 can apply a sufficiently large required installation force in a lever manner.

[0050] Next, combine Figure 5 The use process of the auxiliary installation tool 1 is described.

[0051] In the case where a downward installation force needs to be applied to the mechanical part to be installed, the operator can first extend the joint part of the auxiliary installation tool 1 toward the position of the mechanical part to be installed, so that the joint surface 111 of the joint part abuts against the joint surface of the mechanical part to be installed. In this process, some obstacles that prevent the auxiliary installation tool 1 from engaging with the joint surface of the mechanical part to be installed can be accommodated in the avoidance area of ​​the rod 12; then, the operator selects a component in a suitable position above the rod 12 of the auxiliary installation tool 1 as a force fulcrum, and supports the rod 12 under the force fulcrum; thereafter, the operator holds the handle 13 (the operator's fingers can be accommodated in the ergonomic curved surface of the handle 13) and applies an upward force to the handle 13. At this time, the joint surface 111 can apply a downward force to the mechanical part to be installed to install the mechanical part.

[0052] In the case where an upward installation force needs to be applied to the mechanical part to be installed, the operator can first extend the joint part of the auxiliary installation tool 1 toward the position of the mechanical part to be installed, so that the joint surface 111 of the joint part abuts against the joint surface of the mechanical part to be installed. In this process, some obstacles that prevent the auxiliary installation tool 1 from engaging with the joint surface of the mechanical part to be installed can be accommodated in the avoidance area of ​​the rod 12; then, the operator selects a component in a suitable position below the rod 12 of the auxiliary installation tool 1 as a force fulcrum, and supports the rod 12 above the force fulcrum; thereafter, the operator holds the handle 13 (the operator's palm can be accommodated in the ergonomic curved surface of the handle 13) and applies a downward force to the handle 13. At this time, the joint surface 111 applies an upward force to the mechanical part to be installed to install the mechanical part.

[0053] If there is no component in a suitable position to serve as a force fulcrum, the operator can place the support member 2 in a suitable position as a fulcrum to perform the above operation.

[0054] Although the exemplary embodiments of the present disclosure have been described, it should be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence.
