[0016] The fixing plate is located between the two limiting parts.

[0017] In one embodiment, the sum of the distances between the fixing plate and the two limiting portions in the first direction is not greater than the difference between the maximum outer diameter and the minimum outer diameter of the guide portion.

[0018] In one embodiment, the locking assembly further comprises a locking driving portion drivingly connected to the locking portion, and the locking driving portion is used to drive the locking portion to move toward and away from the locking engagement portion.

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0043] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0044] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0045] The alignment of the instrument assembly with the vehicle body is crucial. After the instrument assembly is assembled to the vehicle body, the left-right gap difference between the left and right ends and the left and right door panels is a key area for appearance evaluation. Therefore, the instrument assembly's Y-axis assembly accuracy is required to be high. Generally, there are two methods for aligning the instrument assembly with the vehicle body: body self-alignment and Y-axis centering.

[0046] The body self-positioning method is to achieve the positioning of the instrument assembly through the locating pin structure on the instrument assembly and the locating holes on the body. During the assembly process, the tooling does not participate in the positioning role and only plays a carrying role; the Y-direction centering method is to achieve the Y-direction centered assembly of the instrument assembly and the body opening, dynamically distribute the left and right gaps with the body, and achieve consistency in the left and right differences in the gaps between the instrument assembly and the body. The left and right clamping arms act simultaneously to clamp the left and right side panel hinge surface areas of the body. According to the deviation of the left and right side panel assembly hinge surface areas, the floating beam moves left and right to achieve dynamic centering assembly of the instrument panel and the body.

[0047] On a multi-model production line, the instrument panel assembly and door panel fit differently across models, leading to varying assembly precision requirements and tooling positioning schemes. Conventional technology typically produces multiple assembly tools to match these positioning schemes. This results in the need to change tools between models, impacting production schedules and making it difficult to store multiple tools.

[0048] The main purpose of the present invention is to propose an instrument assembly tool and assembly equipment, aiming to at least solve the technical problems in the related art of producing multiple different assembly tools corresponding to different positioning schemes, resulting in the need to change tools when producing different models, affecting the production rhythm, and the inconvenience of storing multiple tools.

[0049] See also Figure 1 、 Figure 2 and Figure 3In one embodiment of the present invention, the instrument assembly tool 100 includes a fixed beam 1, a floating beam 2, a clamping assembly, a driving device and a locking assembly 7, wherein the fixed beam 1 extends along a first direction and is used to be fixedly connected to the robotic arm; the floating beam 2 is spaced apart and arranged on one side of the fixed beam 1 in the second direction, and can be movably arranged along the first direction relative to the fixed beam 1; the clamping assembly includes two first clamping parts 3 arranged on the floating beam 2 along the first direction and two second clamping parts 4 arranged between the two first clamping parts 3, wherein the distance between one of the first clamping parts 3 and one of the second clamping parts 4 is the same as the distance between the other first clamping part 3 and the other second clamping part 4 The spacing between the two first clamping parts 3 is equal, the two first clamping parts 3 can move relative to or away from each other along the first direction to clamp the vehicle body or separate from the vehicle body, and the two second clamping parts 4 can move relative to or away from each other along the first direction to clamp or release the instrument assembly; the driving device includes a first driving component 5 and a second driving component 6 which are respectively driven and connected to the two first clamping parts 3 and the two second clamping parts 4; the locking component 7 includes a locking part 71 and a locking matching part 72 which are respectively arranged on the fixed beam 1 and the floating beam 2, and the locking part 71 can move in a direction close to or away from the locking matching part 72 to have a locking position matched with the locking matching part 72 and a separation position separated from the locking matching part 72.

[0050] In the technical solution of the present invention, when it is necessary to assemble the instrument assembly by the self-positioning method of the vehicle body, the locking portion 71 is operated to be close to the locking matching portion 72, so that the locking portion 71 is in the locking position and cooperates with the locking matching portion 72. At this time, the floating beam 2 remains fixed relative to the fixed beam 1. After the instrument assembly is assembled by the two second clamping portions 4, the instrument assembly is transferred to the corresponding position of the vehicle body by a robotic arm, and the assembly is completed by adaptive positioning of the instrument assembly and the corresponding structures on the vehicle body; when it is necessary to assemble the instrument assembly by the Y-axis centering method, the locking portion 71 is operated to move to the separation position. At this time, the floating beam 2 can move relative to the fixed beam 1 along the first direction, and the instrument assembly is clamped by the two second clamping portions 4. The entire tooling is transferred to the approximate position of the vehicle body by a robotic arm, and then the two first clamping portions 3 are moved relative to each other. Clamping the vehicle body, since the distance between one of the first clamping parts 3 and one of the second clamping parts 4 is equal to the distance between another first clamping part 3 and another second clamping part 4, that is, the instrument assembly after being clamped is at the center of the two first clamping parts 3, and in the process of the first clamping parts 3 clamping the vehicle body, the robotic arm remains stationary, and one of the first clamping parts 3 first contacts the vehicle body, and the support of the first clamping part 3 and the vehicle body enables the floating beam 2 to move relative to the fixed beam 1 along the first direction until the two first clamping parts 3 respectively contact the opposite sides of the vehicle body, at which time the centering of the instrument assembly and the vehicle body is completed, and the instrument assembly is then fixed to the vehicle body; with such a setting, different assembly methods can be switched through an instrument assembly assembly tool 100, and there is no need to change work and affect the production rhythm when producing different models, and it is convenient for storage.

[0051] The locking portion 71 and the locking fitting portion 72 need to limit the movement of the floating beam 2 relative to the fixed beam 1 along the first direction, wherein the locking portion 71 has multiple movement modes, for example, the locking portion 71 rotates and can cooperate with or separate from the locking fitting portion 72 during the rotation process. In an embodiment of the invention, the locking portion 71 is set to slide along the second direction relative to the locking fitting portion 72 so as to have the locking position and the separation position within its sliding stroke.

[0052] The movement of the locking portion 71 can be manually operated or automatically driven by a driving element. In an embodiment of the present invention, the locking assembly 7 further includes a locking driving portion 75 drivingly connected to the locking portion 71. The locking driving portion 75 is configured to drive the locking portion 71 toward and away from the locking engagement portion 72. Thus, the locking driving portion 71 is automatically driven by the locking driving portion 75, which improves production efficiency and eliminates the need for workers to enter between the vehicle body and the tooling, thereby ensuring personal safety.

[0053] This design does not limit the specific form of the locking drive part 75, and its specific form is also related to the activity form of the locking part 71. For example, when the locking part 71 is rotating, the locking drive part 75 can be a motor to drive the rotation of the locking part 71; in this embodiment, the locking part 71 slides along the second direction, and the locking drive part 75 can be a cylinder, an electric push rod or a threaded structure to drive the linear movement of the locking part 71.

[0054] There are many ways of matching the locking portion 71 and the locking matching portion 72. In this embodiment, please refer to Figure 2 and Figure 3 One of the fixed beam 1 and the floating beam 2 is fixedly provided with a fixed plate 73, and the other is provided with a latch 711 that slides along the second direction. The fixed plate 73 is provided with a positioning hole 731 extending along the second direction; the latch 711 constitutes the locking portion 71, and the positioning hole 731 constitutes the locking engagement portion 72. Thus, when in the locked position, the latch 711 moves along the second direction into the positioning hole 731 along the second direction. The two side walls of the positioning hole 731 located in the first direction can restrict the movement of the latch 711 in the first direction. Since the latch 711 and the positioning hole 731 are respectively provided on the floating beam 2 and the fixed beam 1, the movement of the floating beam 2 relative to the fixed beam 1 in the first direction can be restricted. When unlocking is required, the locking portion 71 is operated to move until it is separated from the locking engagement portion 72. The matching form of the locking portion 71 and the locking matching portion 72 is not limited to this. In another embodiment, the locking matching portion 72 can be two baffles spaced apart along the first direction, and a limiting channel is formed between the two baffles to limit the movement of the locking portion 71 through the limiting channel.

[0055] It is understandable that, since the floating beam 2 can move relative to the fixed beam 1 along the first direction, the latch 711 and the positioning hole 731 may not be aligned and there is no way to lock the floating beam 2 and the fixed beam 1, and manual adjustment is required. Therefore, in this embodiment, please refer to Figure 2 and Figure 3The end of the latch 711 close to the positioning hole 731 is provided with a guide portion 712, and the outer diameter of the guide portion 712 is gradually reduced in the direction close to the positioning hole 731; with this arrangement, there is no need to completely align the latch 711 and the positioning hole 731, and the latch 711 only needs to be located in an approximate position. When the latch 711 moves toward the positioning hole 731, the gradually reduced guide portion 712 can contact the side wall of the positioning hole 731, and cooperate with the movement of the floating beam 2 to guide the latch 711 to align with the positioning hole 731, thereby reducing the difficulty of matching the latch 711 and the positioning hole 731.

[0056] In order to further reduce the difficulty of matching the latch 711 and the positioning hole 731 to prevent the latch 711 from getting stuck, in the embodiment of the present invention, please refer to Figure 3 The locking assembly 7 further includes two limiting portions 74, which are spaced apart in the first direction and arranged adjacent to one of the fixed beam 1 and the floating beam 2 where the latch 711 is located. The fixing plate 73 is located between the two limiting portions 74. Thus, the two limiting portions 74 limit the range of motion of the fixed beam 1 and the floating beam 2, i.e., limit the deviation between the guide portion 712 and the positioning hole 731 to within a certain range. This allows the latch 711 to move directly in the second direction to engage with the positioning hole 731 without manually adjusting the relative position of the floating beam 2 and the fixed beam 1.

[0057] It should be noted that when assembling the instrument assembly, the robotic arm will move the entire tooling to an approximate position in advance. Although this approximate position will not ensure that the instrument assembly is exactly in the middle of the vehicle body, the left and right position deviations will not be too large, that is, when assembled in the Y-axis centering manner, the range of movement of the floating beam 2 relative to the fixed beam 1 along the first direction does not need to be too large, so the setting of the limit portion 74 will not affect the Y-axis centering assembly of the entire tooling.

[0058] In order to ensure that the latch 711 can cooperate with the positioning hole 731 when it moves in the second direction toward the positioning hole 731 at any position, in the embodiment of the present invention, please refer to Figure 3, the sum of the distances between the fixing plate 73 and the two limiting parts 74 in the first direction is not greater than the difference between the maximum outer diameter and the minimum outer diameter of the guide part 712; with such an arrangement, after limiting the range of movement of the floating beam 2 by the limiting part 74, no matter which position the floating beam 2 is in, when directly driving the pin 711 to move, it can ensure that the guide part 712 first contacts the side wall of the positioning hole 731, thereby guiding the floating beam 2 to move through the guide part 712 until the pin 711 is matched with the positioning hole 731.

[0059] In order to make the two first clamping parts 3 move synchronously, in this embodiment, please refer to Figure 4 The first driving assembly 5 includes a rotating member 51, a connecting rod 52, and a driving member 53. The rotating member 51 is rotatably mounted on the floating beam 2 along an axis extending in the third direction. Two connecting rods 52 are provided, and the two connecting rods 52 respectively hinge the ends of the rotating member 51 and the two first clamping parts 3. The driving member 53 is drivably connected to the rotating member 51 to drive the rotating member 51 to rotate. With this arrangement, when the driving member 53 is activated, it drives the rotating member 51 to rotate, thereby causing the angles of the two connecting rods 52 to change simultaneously in opposite directions, ultimately causing the two first clamping parts 3 to synchronously move relative to each other or move away from each other, ensuring that the center line of the line connecting the two first clamping parts 3 and the center line of the line connecting the two second clamping parts 4 overlap.

[0060] There are various ways to drive the rotation of the rotating member 51. In this embodiment, the driving member 53 includes a pusher 531 and a transmission rod 532. The pusher 531 is mounted on the floating beam 2, with its output end movably arranged in the transverse direction. One end of the transmission rod 532 is rotationally connected to the output end of the pusher 531, and the other end is rotationally connected to the rotating member 51. In this manner, the rotating member 51 is driven by pushing. When the pushing member is activated, the transmission rod 532 is hingedly connected to the rotating member 51, causing the angle of the transmission rod 532 to change, thereby driving the rotation of the rotating member 51. In another embodiment, the rotating member 51 can be directly driven by a motor.

[0061] The pushing part 531 may be a cylinder, an electric push rod or a threaded pair structure.

[0062] In an embodiment of the invention, the second driving component 6 can adopt a connecting rod structure similar to the first driving component 5 to drive the two second clamping parts 4 to move relative to or away from each other, or can adopt a gear rack structure or a bidirectional thread pair structure; similarly, the first driving component 5 can also adopt a gear rack structure or a bidirectional thread pair structure, as long as it can drive the two first clamping parts 3 and the two second clamping parts 4 to move relative to or away from each other synchronously.

[0063] The present invention further provides an assembly device comprising a robotic arm and an instrument assembly assembly tool 100. The specific structure of the instrument assembly tool 100 is similar to that of the aforementioned embodiments. Since the present assembly device utilizes all of the technical solutions of all of the aforementioned embodiments, it possesses at least all of the beneficial effects provided by the technical solutions of the aforementioned embodiments, and therefore, a detailed description thereof will not be repeated here. The fixed beam 1 of the instrument assembly tool 100 is fixedly connected to the output end of the robotic arm.

[0064] In the technical solution of the present invention, when it is necessary to assemble the instrument assembly by the self-positioning method of the vehicle body, the locking portion 71 is operated to be close to the locking matching portion 72, so that the locking portion 71 is in the locking position and cooperates with the locking matching portion 72. At this time, the floating beam 2 remains fixed relative to the fixed beam 1. After the instrument assembly is assembled by the two second clamping portions 4, the instrument assembly is transferred to the corresponding position of the vehicle body by a robotic arm, and the assembly is completed by adaptive positioning of the instrument assembly and the corresponding structures on the vehicle body; when it is necessary to assemble the instrument assembly by the Y-axis centering method, the locking portion 71 is operated to move to the separation position. At this time, the floating beam 2 can move relative to the fixed beam 1 along the first direction, and the instrument assembly is clamped by the two second clamping portions 4. The entire tooling is transferred to the approximate position of the vehicle body by a robotic arm, and then the two first clamping portions 3 are moved relative to each other. Clamping the vehicle body, since the distance between one of the first clamping parts 3 and one of the second clamping parts 4 is equal to the distance between another first clamping part 3 and another second clamping part 4, that is, the instrument assembly after being clamped is at the center of the two first clamping parts 3, and in the process of the first clamping parts 3 clamping the vehicle body, the robotic arm remains stationary, and one of the first clamping parts 3 first contacts the vehicle body, and the support of the first clamping part 3 and the vehicle body enables the floating beam 2 to move relative to the fixed beam 1 along the first direction until the two first clamping parts 3 respectively contact the opposite sides of the vehicle body, at which time the centering of the instrument assembly and the vehicle body is completed, and the instrument assembly is then fixed to the vehicle body; with such a setting, different assembly methods can be switched through an instrument assembly assembly tool 100, and there is no need to change work and affect the production rhythm when producing different models, and it is convenient for storage.
