[0032] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the specific technical solutions of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application but are not intended to limit the scope of the present application.

[0033] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of this application, unless otherwise specified, "multiple" means two or more.

[0034] In addition, in the embodiments of the present application, directional terms such as "up", "down", "left" and "right" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they may change accordingly according to changes in the orientation of the components in the drawings.

[0035] In the embodiments of the present application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integrated connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0036] In the embodiments of the present application, the terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of other identical elements in the process, method, article, or apparatus comprising the element.

[0037] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0038] An embodiment of the present application provides an assembly tool 100, which is used to install a front hood on a vehicle body. It should be noted that the assembly tool 100 in the present application can install the front hood on a large car, a small car, a special-purpose vehicle, etc. For example, according to the vehicle model, the vehicle on which the assembly tool 100 in the present application installs the front hood can be a sedan model, an off-road model, a multi-purpose vehicle (MPV) model or other models.

[0039] An automobile manufacturer needed to introduce a new model to its existing front hood assembly line. To meet the new model's design and dimensional control requirements for exterior clearance and flushness, the manufacturer required that the front hood be assembled with the hinges and body-side bolts tightened while the hood was closed. This was inconsistent with the front hood assembly process for other models currently produced on the line, which tighten the hinges and body-side bolts with the hood open. To adapt the assembly tool 100 to two front hood assembly angles (open and closed), the tool needed to be modified.

[0040] On this basis, refer to Figure 4-Figure 7 The embodiment of the present application provides an assembly tool 100, which includes: a tool body 10, a fixing assembly 30, and a drive assembly 20. The drive assembly 20 is fixed to the tool body 10. The drive assembly 20 can be fixedly mounted on the tool body 10 or detachably mounted on the tool body 10. If the drive assembly 20 is detachably mounted on the tool body 10, if a problem occurs with the drive assembly 20 later and requires repair, the drive assembly 20 can be removed from the tool body 10, which can facilitate repair of the drive assembly 20. If the drive assembly 20 has a problem that cannot be repaired, a new drive assembly 20 can be replaced.

[0041] The fixing assembly 30 is used to fix the tooling part 60, which can be the front cover of a car. The fixing assembly 30 is connected to the driving assembly 20. When the driving assembly 20 is working, it can drive the fixing assembly 30 to move, change the position of the fixing assembly 30, and then cover the position of the tooling part 60, and drive the tooling part 60 to a position suitable for assembly.

[0042] The driving assembly 20 is used to drive the fixing assembly 30 to move between a first position and a second position. The first position may be the position where the tooling part 60 is initially fixed to the fixing assembly 30, that is, the initial fixing position of the tooling part 60; the second position may be the position where the tooling part 60 is assembled to the automobile, that is, the assembly position of the tooling part 60. The driving assembly 20 is used to drive the fixing assembly 30 to move between the first position and the second position. In other words, the driving assembly 20 can transfer the tooling part 60 from the initial fixing position to the assembly position, thereby facilitating the transfer and assembly of the tooling part 60.

[0043] The assembly tool 100 also includes a limiter 40, which is detachably mounted on the tool body 10. After being mounted on the tool body 10, the limiter 40 can be used to limit the range of motion of the drive assembly 20. When the drive assembly 20 contacts the limiter 40, the limiter 40 can prevent the drive assembly 20 from continuing to move, allowing the fixing assembly 30 to be located in a third position between the first position and the second position. The third position can be another assembly position for the tool 60 to be assembled to the vehicle. In addition, after the limiter 40 is removed from the tool body 10, the limiter 40 no longer limits the range of motion of the drive assembly 20, allowing the fixing assembly 30 to move from the first position to the second position, or from the second position to the first position.

[0044] The driving component 20 can drive the tooling part 60 to move between the first position and the second position, providing a suitable assembly position for the tooling part 60. At the same time, a limiter 40 is provided on the tooling body 10. The limiter 40 can limit the movement range of the driving component 20 so that the fixing component 30 can be located at a third position between the first position and the second position, so that the tooling part 60 can adapt to two different assembly positions.

[0045] The driving component 20 drives the fixing component 30 to move to the first position, the fixing component 30 fixes the tooling part 60, and then the driving component 20 drives the fixing component 30 to move. When the driving component 20 reaches the end of the stroke, the fixing component 30 is located at the second position for assembling the tooling part 60; when a workpiece in another assembly position needs to be installed, the driving component 20 drives the fixing component 30 to move to the first position, and then fixes the limit member 40 to the tooling body 10, and then the fixing component 30 fixes the tooling part 60. The driving component 20 drives the fixing component 30 to move. When the driving component 20 contacts the limit member 40, the fixing component 30 is located at the third position for assembling the tooling part 60.

[0046] In the assembly tool 100 provided in an embodiment of the present application, the driving component 20 can drive the tooling part 60 to move between a first position and a second position. At the same time, a limit member 40 is provided on the tooling body 10. The limit member 40 can limit the movement range of the driving component 20 so that the fixing component 30 can be located at a third position between the first position and the second position, so that the tooling part 60 can adapt to a variety of assembly positions.

[0047] Reference Figure 4-Figure 8In some embodiments of the present application, the drive assembly 20 includes a drive cylinder 21 and a rotating member 22. The drive cylinder 21 is hinged to the tool body 10. The rotating member 22 has a rotation center 223 fixedly connected to the tool body 10. One end of the rotating member 22 is hinged to the drive cylinder 21, and the other end of the rotating member 22 is connected to the fixed assembly 30. The drive cylinder 21 and the rotating member 22 are arranged in a triangle.

[0048] When the fixing assembly 30 needs to move from the first position to the second position, since one end of the driving cylinder 21 is hinged to the tooling body 10, and the other end of the driving cylinder 21 is hinged to the rotating part 22, the telescopic rod 212 of the driving cylinder 21 is extended and retracted in the cylinder body 211 of the driving cylinder 21. The driving cylinder 21 can drive the rotating part 22 to rotate around the rotation center 223, and can drive the fixing assembly 30 to move, so as to change the position of the fixing assembly 30, and then change the position of the tooling part 60, so that the tooling part 60 reaches the assembly position.

[0049] Reference Figure 4-Figure 8 In some embodiments of the present application, the driving cylinder 21 includes a cylinder body 211 and a telescopic rod 212. The telescopic rod 212 is telescopically located within the cylinder body 211. Two rotating members 22 are provided. The two rotating members 22 are respectively hingedly connected to the cylinder body 211 on both radial sides. The telescopic rod 212 is hingedly connected to the tool body 10. When the telescopic rod 212 is extended or retracted, it can drive the two rotating members 22 to rotate around the rotation center 223. The two rotating members 22 can increase the strength of the connection between the driving cylinder 21 and the fixed assembly 30. The two rotating members 22 are located on both radial sides of the cylinder body 211, so that the rotating members 22 have a certain distance on the diameter of the cylinder body 211, so that the two rotating members 22 can be fixed to the fixed assembly 30 at intervals. When the rotating member 22 pulls the fixed assembly 30 to move, it can pull different positions of the fixed assembly 30, thereby preventing the fixed assembly 30 from shifting in position during movement.

[0050] Reference Figure 4-Figure 8 In some embodiments of the present application, the rotating member 22 includes a rotating bracket 221 and a connecting plate 222. One end of the rotating bracket 221 is hinged to the driving cylinder 21, and the other end of the rotating bracket 221 is fixedly connected to the connecting plate 222. The connecting plate 222 fits with the fixing plate 31 of the fixing assembly 30, which can increase the contact area between the connecting plate 222 and the fixing plate 31 of the fixing assembly 30, thereby increasing the connection strength between the connecting plate 222 and the fixing assembly 30.

[0051] The rotating bracket 221 is provided with a weight-reducing hole 2211 , which can reduce the weight of the rotating bracket 221 . For example, the weight-reducing hole 2211 can be a triangular hole that matches the shape of the rotating bracket 221 .

[0052] Reference Figure 1-Figure 3In some embodiments of the present application, the fixing assembly 30 further includes a suction cup 32 , which is used to suck the tooling piece 60 . Using the suction cup 32 to fix the tooling piece 60 can simplify the method of fixing the tooling piece 60 of the fixing assembly 30 .

[0053] Alternatively, the fixing assembly 30 includes not only a suction cup 32, but also a clamp, wherein the suction cup 32 and the clamp are both connected to the fixing plate 31, and the clamp is located on the peripheral side of the suction cup 32. The suction cup 32 is used to suck the tooling part 60, and the clamp is used to fix the peripheral side of the tooling part 60. Under the joint action of the suction cup 32 and the clamp, the connection strength of the tooling part 60 fixed to the fixing assembly 30 can be increased.

[0054] Reference Figure 6-Figure 8 In some embodiments of the present application, the limiting member 40 includes a limiting pin 41. One end of the limiting pin 41 is installed in a fixing hole 52 of the tool body 10, and the other end of the limiting pin 41 extends out of the fixing hole 52. When the limiting pin 41 of the drive assembly 20 abuts the portion extending from the fixing hole 52, the fixing assembly 30 is located in the third position, that is, the tooling member 60 is located in the third position. By installing the limiting pin 41 in the fixing hole 52 of the tool body 10, the installation of the limiting pin 41 can be simplified.

[0055] When the limit pin 41 is not needed to limit the movement stroke of the drive assembly 20, the operator can pull the limit pin 41 out of the fixing hole 52 and place it in a fixed position; when the limit pin 41 is needed to limit the movement stroke of the drive assembly 20, the operator can install the limit pin 41 into the fixing hole 52.

[0056] Reference Figure 6-Figure 8 In some embodiments of the present application, the tool body 10 further includes a limit seat 50, which extends toward the drive assembly 20 and has a fixing hole 52. The limit seat 50 extends toward the drive assembly 20, and after the limit pin 41 is installed in the fixing hole 52 of the limit seat 50, the limit pin 41 can interfere with the drive assembly 20 in movement, thereby maintaining the drive assembly 20 in the third position.

[0057] Reference Figure 5-Figure 8 In some embodiments of the present application, the limit seat 50 includes a first support plate 51 and a second support plate spaced apart from each other. The first support plate 51 and the second support plate both have fixing holes 52. The two ends of the limit pin 41 are respectively passed through the two fixing holes 52. The two fixing holes 52 can be supported at the two ends of the limit pin 41, so that the limit pin 41 can maintain balance. When the driving component 20 abuts against the limit pin 41, the limit pin 41 is not prone to position displacement, so that the position of the fixing component 30 when it is maintained in the third position is more accurate.

[0058] Reference Figure 7-Figure 8 In some embodiments of the present application, the drive assembly 20 includes a drive cylinder 21, a first support plate 51, and a second support plate, respectively, located on either radial side of the drive cylinder 21. When the limit pin 41 is installed in the fixing hole 52, the limit pin 41 is located in the axial direction of the drive cylinder 21. The drive assembly 20 also includes a rotating member 22, which is hinged to one radial side of the drive cylinder 21 and is arranged at an angle to the drive cylinder 21. When the drive cylinder 21 pulls the rotating member 22 to move, the limit pin 41 is installed in the fixing hole 52, and the rotating member 22 can abut against the limit pin 41.

[0059] Reference Figure 4 、 Figure 6 In some embodiments of the present application, in the second position, the plane of the tooling member 60 is parallel to the horizontal plane, suitable for horizontal installation of the tooling member 60 on the vehicle. For example, the tooling member 60 is a front hood, and the front hood hinge and the body side bolts are tightened when the front hood is in the closed state.

[0060] In the third position, the plane of the tooling 60 forms a 30° angle with the horizontal plane, suitable for installing the tooling 60 at a 30° angle on the vehicle. For example, the tooling 60 is a front hood, and the front hood hinge and the body side bolts are tightened when the front hood is in the open state.
