[0001] This application belongs to the technical field of door installation equipment, and particularly relates to a connection component and a door installation equipment. Background Art

[0002] During the production process of the body-in-white in welding, it is necessary to ensure the accurate clearance and surface difference between the rear door and the surrounding accessories to ensure the appearance quality of the vehicle, as well as the sealing performance and closing force of the rear door.

[0003] The rear door of the vehicle is relatively heavy. Generally, a combination of a power-assisted robotic arm and a tooling fixture is used to assemble and position the rear door so that the position of the rear door on the vehicle body is in a controlled state.

Detailed description of the invention

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts fall within the protection scope of the present invention.

[0048] It should be noted that all directional indications in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If this specific posture changes, the directional indications will also change accordingly.

[0050] In addition, in the present invention, descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0051] In the related art, when multiple vehicle models are mixed on the production line, there are technical problems such as the large space occupied by the assisting robotic arm and the high investment cost. The embodiments of the present application provide a connecting component and a door installation device, which can at least to a certain extent solve the technical problems of the large space occupied by the assisting robotic arm and the high investment cost when multiple vehicle models are mixed on the production line.

[0052] The following describes the present application with reference to the accompanying drawings and specific embodiments:

[0053] As Figures 1 to 6As shown, the connecting component 100 is used to connect the power-assisted arm 200 and the tooling jig 300 for fixing the vehicle door 2000, and includes a support mechanism 110, a connecting mechanism 120, a connecting piece 130 and an adjusting piece 140. The support mechanism 110 is connected to the power-assisted arm 200; the connecting mechanism 120 is rotatably connected to the support mechanism 110, and the rotating shaft of the connecting mechanism 120 is arranged along the Y direction; the connecting piece 130 is detachably connected to the connecting mechanism 120 and is connected to the tooling jig 300; the adjusting piece 140 is installed on the support mechanism 110, and its output end abuts against the tooling jig 300, driving the tooling jig 300 to rotate around the rotating shaft of the connecting mechanism 120 to change the pitching angle α of the tooling jig 300.

[0054] The tooling jig 300 can fix the vehicle door 2000, and can be provided with cylinder jaws or the like to clamp the door 2000, and its structure is not limited in this application. The support mechanism 110 is the installation base of the connecting mechanism 120 and the adjusting piece 140, and supports the connecting mechanism 120 and the adjusting piece 140. The support mechanism 110 is fixedly connected to the power-assisted arm 200, and the support mechanism 110 is fixed at the output end of the power-assisted arm 200. The connecting mechanism 120 is rotatably connected to the support mechanism 110, and the connecting mechanism 120 can rotate around the support mechanism 110. The connecting piece 130 and the connecting mechanism 120 are detachably connected, such as bolt connection, snap connection, etc. The tooling jig 300 is fixedly connected to the connecting piece 130. The tooling jig 300 and the connecting piece 130 can be detachably connected or non-detachably connected, which is not limited in this application. The adjusting piece 140 is installed on the support mechanism 110, and its output end can move, and can move in the direction towards the tooling jig 300 or away from the tooling jig 300. The tooling jig 300 is connected to the connecting piece 130, the connecting piece 130 is connected to the connecting mechanism 120, and the connecting mechanism 120 is rotatably connected to the support mechanism 110 again. Therefore, the tooling jig 300 can rotate. In this way, when the output end of the adjusting piece 140 extends different lengths, the pitching angle α of the tooling jig 300 is different. Therefore, the adjusting piece 140 can drive the tooling jig 300 to rotate around the rotating shaft of the connecting mechanism 120 to adjust the pitching angle α of the tooling jig 300. The structure of the power-assisted arm 200 is diverse and is well known to those skilled in the art. Since the support mechanism 110 is connected to the power-assisted arm 200, the power-assisted arm 200 can drive the connecting component 100, the tooling jig 300 thereon, and the vehicle door 2000 on the tooling jig 300 to move in multiple directions, so that the vehicle door 2000 can be aligned with the peripheral accessories of the white vehicle body and the installation can be completed.

[0055] Since the connecting member 130 is detachably connected to the connecting mechanism 120, the connecting member 130 and the tooling jig 300 thereon can be removed from the connecting mechanism 120. By providing a plurality of connecting members 130 and respectively installing tooling jigs 300 suitable for different models of the vehicle door 2000 on each connecting member 130, the assisting arm 200 can be connected to different types of tooling jigs 300, enabling the assisting arm 200 to drive different types of vehicle doors 2000 and realizing the installation of different types of vehicle doors 2000. After such a design, different types of tooling jigs 300 can share the same assisting arm 200. When multiple vehicle models are produced on the same production line, the number of assisting arms 200 can be reduced, thereby reducing the number of workstations for the assisting arms 200 and the space occupied by the assisting arms 200, saving production costs. Different types of tooling jigs 300 require different pitching angles α. The connecting mechanism 120 is rotatably connected to the supporting mechanism 110, and the adjusting member 140 is installed on the supporting mechanism 110, and its output end abuts against the tooling jig 300, so that the pitching angle α of the tooling jig 300 can be adjusted by controlling the position of the output end of the adjusting member 140, enabling different types of vehicle doors 2000 to be flipped at different pitching angles α, facilitating the installation of different types of vehicle doors 2000 and helping to improve the installation efficiency of the vehicle doors 2000.

[0056] In the present application, the Y-direction, X-direction, and Z-direction are perpendicular to each other.

[0057] In some embodiments, the connecting mechanism 120 includes a mounting seat 121, a connecting seat 122, and a locking member 123. The mounting seat 121 is rotatably connected to the supporting mechanism 110; the connecting seat 122 is connected to the mounting seat 121, having a receiving cavity 122a for receiving the connecting member 130 and a jack 122b communicating with the receiving cavity 122a, and the connecting member 130 is located in the receiving cavity 122a through the jack 122b; the locking member 123 is installed on the connecting seat 122, having a locking position located in the receiving cavity 122a and engaging with the connecting member 130 and an unlocking position separated from the connecting member 130.

[0058] The connecting base 122 is fixedly connected to the mounting base 121, and is provided with a receiving cavity 122a and a jack 122b thereon. The locking member 123 is mounted on the connecting base 122. It should be noted that the locking member 123 can move towards the direction close to the connecting member 130 or move away from the connecting member 130. When the locking member 123 moves towards the direction close to the connecting member 130, the locking member 123 can be clamped on the connecting member 130, so that the connecting member 130 is clamped in the receiving cavity 122a and cannot be disengaged, realizing the connection between the connecting member 130 and the connecting mechanism 120. At this time, the locking member 123 is in the locking position. When the locking member 123 moves away from the connecting member 130, the locking member 123 gradually moves away from the connecting member 130, and the locking member 123 is separated from the connecting member 130 and no longer clamps the connecting member 130. At this time, the locking member 123 is in the unlocking position. After the locking member 123 does not clamp the connecting member 130, the connecting member 130 can be disengaged from the receiving cavity 122a, realizing the separation between the connecting member 130 and the connecting mechanism 120. After such a design, after the connecting member 130 is inserted into the receiving cavity 122a from the jack 122b, the locking member 123 is controlled to move towards the direction close to the connecting member 130, so that the locking member 123 is clamped on the connecting member 130 and is in the locking position, and the connecting member 130 can be fixed to the connecting mechanism 120. When it is necessary to replace the tooling sample rack 300, the locking member 123 is controlled to move away from the connecting member 130, so that the locking member 123 no longer clamps the connecting member 130 and is in the unlocking position, and the connecting member 130 can be disassembled from the connecting mechanism 120. The installation and disassembly efficiency of the connecting member 130 is higher, which helps to improve the replacement efficiency of the tooling sample rack 300 and the installation efficiency of the vehicle door 2000.

[0059] As Figure 7 , Figure 8 and Figure 9 shown, in some embodiments, the connecting member 130 includes an insertion portion 131, a connecting portion 132, and a stopping portion 132. The insertion portion 131 is located in the receiving cavity 122a, and a clamping interface 131a is provided on the insertion portion 131. Under the condition that the locking member 123 is in the locking position, at least a part of the locking member 123 is located in the clamping interface 131a. The connecting portion 132 is connected to the insertion portion 131 and the tooling sample rack 300 and is located outside the receiving cavity 122a. The stopping portion 133 is connected to the connecting portion 132 and protrudes outside the jack 122b.

[0060] The insertion part 131, the connection part 132, and the stop part 133 are fixedly connected to each other and can be integrally formed. When the connecting member 130 is connected to the connecting mechanism 120, the insertion part 131 is inserted into the accommodation cavity 122a through the insertion hole 122b, and one end of the locking member 123 close to the insertion part 131 extends into the clamping interface 131a to form a clamping connection with the insertion part 131, and the insertion part 131 is thus clamped in the accommodation cavity 122a. When one end of the locking member 123 close to the insertion part 131 extends out of the clamping interface 131a and is located outside the clamping interface 131a, the insertion part 131 can be pulled out from the insertion hole 122b. The stop part 133 protrudes outside the insertion hole 122b, that is to say, the size of the stop part 133 is larger than the size of the insertion hole 122b, and the stop part 133 cannot extend into the insertion hole 122b. After such a design, the stop part 133 can be used for limiting. When the insertion part 131 extends until the stop part 133 abuts against the connection seat 122, it cannot be inserted further, and the insertion part 131 extends in place. Then, the locking member 123 can be operated to make the locking member 123 located in the clamping interface 131a and clamped with the insertion part 131, which facilitates the user to use the connection assembly 100.

[0061] In some embodiments, along the Z direction, both the stop part 132 and the connection part 132 are arranged below the insertion part 131.

[0062] In some embodiments, the connection part 132 also protrudes outside the insertion hole 122b, that is to say, the size of the connection part 132 is larger than the size of the insertion hole 122b, and the connection part 132 cannot extend into the insertion hole 122b either. The connection part 132 and the stop part 133 limit together.

[0063] In some embodiments, a plurality of pin holes and a plurality of threaded holes are machined on the connection part 132. The tooling sample rack 300 and the connection part 132 are positioned by pins located in the pin holes and fixedly connected by bolts or screws in the threaded holes.

[0064] In some embodiments, the stop part 132 is arranged on the side of the connection part 132 away from the mounting seat 121.

[0065] In some embodiments, the connecting mechanism 120 is provided with two locking members 123, and the insertion part 131 is provided with two clamping interfaces 131a. The two locking members 123 and the two clamping interfaces 131a are arranged opposite to each other along the Y direction. Under the condition that the locking members 123 are in the locking positions, the two locking members 123 are respectively inserted into the two clamping interfaces 131a along the Y direction.

[0066] The rotating shaft extends along the Y direction. The two locking members 123 are arranged oppositely along the Y direction, and the two clamping interfaces 131a are also arranged oppositely along the Y direction. The locking members 123 and the clamping interfaces 131a are in one-to-one correspondence. That is to say, one of the locking members 123 is inserted into one of the clamping interfaces 131a, and the other locking member 123 is inserted into the other clamping interface 131a. After such a design, the two locking members 123 respectively clamp the two opposite sides of the connecting member 130 along the Y direction, and the clamping of the connecting member 130 is more reliable, so that the connecting member 130 can be more reliably connected to the connecting mechanism 120.

[0067] As Figure 10 and Figure 11 shown, in some embodiments, the locking member 123 includes a fixing member 1231, a sliding member 1232 and a reset member 1233. The fixing member 1231 is connected to the connecting seat 122; the sliding member 1232 is slidably connected to the fixing member 1231 and has a first end 12321 and a second end 12322 arranged oppositely. The first end 12321 is located outside the accommodating cavity 122a, and the second end 12322 is located inside the accommodating cavity 122a and is clamped with the connecting member 130; the reset member 1233 acts on the fixing member 1231 and the sliding member 1232 to apply a force to the sliding member 1232 in the direction towards the connecting member 130.

[0068] It is easy to understand that the connecting seat 122 is provided with an installation hole for the sliding member 1232 to extend into the accommodating cavity 122a. In these embodiments, the sliding member 1232 has a locking position and an unlocking position. The fixing member 1231 is fixedly connected to the connecting seat 122, the sliding member 1232 is slidably connected to the fixing member 1231, and the second end 12322 of the sliding member 1232 extends into the accommodating cavity 122a through the installation hole. The first end 12321 of the sliding member 1232 is located outside the accommodating cavity 122a, so that the user can control the position of the second end 12322 by applying a force to the first end 12321, so that the second end 12322 is located inside or outside the clamping interface 131a. One end of the reset member 1233 acts on the fixing member 1231, and the other end acts on the sliding member 1232. The reset member 1233 always applies a force to the sliding member 1232 in the direction towards the connecting member 130. After such a design, when no force is applied to the first end 12321 of the sliding member 1232, the second end 12322 of the sliding member 1232 is located inside the accommodating cavity 122a. After the insertion portion 131 is inserted into the accommodating cavity 122a, the second end 12322 can automatically be clamped in the clamping interface 131a, realizing the rapid installation of the connecting member 130; applying a force to the first end 12321 to make the sliding member 1232 move towards the side away from the connecting member 130 can make the second end 12322 located outside the clamping interface 131a, which helps to realize the rapid disassembly of the connecting member 130.

[0069] In some embodiments, along the Z direction, the jack 122b is arranged on the lower end surface of the connection base 122. After such a design, the connecting member 130 moves upward from the bottom and is inserted into the accommodation cavity 122a. When replacing the tooling sample rack 300, the operator lifts the tooling sample rack 300 so that the insertion portion 131 of the connecting member 130 on the tooling sample rack 300 is located below the jack 122b and aligned with the jack 122b, and then lifts the tooling sample rack 300 again so that the insertion portion 131 is inserted into the jack 122b. When disassembling the tooling sample rack 300, the operator separates the locking member 123 and the connecting member 130, and then allows the tooling sample rack 300 to move downward along the gravity until the insertion portion 131 of the connecting member 130 is outside the accommodation cavity 122a, thus completing the disassembly of the tooling sample rack 300. When installing and disassembling the tooling sample rack 300, the operator does not need to make the connecting member 130 higher than the connection base 122, which facilitates the operator to install and disassemble the tooling sample rack 300.

[0070] In some embodiments, along the Z direction, a guiding inclined surface is provided at the upper end of the insertion portion 131 to facilitate the insertion of the insertion portion 131 into the jack 122b.

[0071] In some embodiments, the connection base 122 further has a first observation hole 122c that communicates with the accommodation cavity 122a and is opened along the Z direction, and a second observation hole 122d that is opened along the X direction.

[0072] Both the first observation hole 122c and the second observation hole 122d communicate with the accommodation cavity 122a. In this way, the position of the insertion portion 131 in the accommodation cavity 122a can be observed through the first observation hole 122c and the second observation hole 122d to determine whether the insertion portion 131 is inserted in place. Moreover, it is also possible to observe whether the insertion portion 131 is aligned with the jack 122b through the first observation hole 122c and the second observation hole 122d, which helps to improve the disassembly and assembly efficiency of the connecting member 130.

[0073] In some embodiments, the support mechanism 110 and the mounting base 121 have an X-direction interval; the support mechanism 110 and / or the mounting base 121 are provided with a first limiting member 124 and a second limiting member 125 that are located in the X-direction interval and arranged along the X direction; along the Z direction, the first limiting member 124 and the second limiting member 125 are respectively located on both sides of the rotating shaft of the connecting mechanism 120.

[0074] That is to say, the connecting mechanism 120 further includes a first limiting member 124 and a second limiting member 125, and the first limiting member 124 and the second limiting member 125 are located between the mounting base 121 and the support mechanism 110. The first limiting member 124 can be installed on the mounting base 121 or on the support mechanism 110. Similarly, the second limiting member 125 can be installed on the mounting base 121 or on the support mechanism 110. As Figure 2As shown, among the first limiting member 124 and the second limiting member 125, one is located on the upper side of the rotating shaft and the other is located on the lower side of the rotating shaft. The support mechanism 110 is located on the movement paths of the first limiting member 124 and the second limiting member 125.

[0075] The directions of the first rotation direction a and the second rotation direction b are opposite. After such a design, after the mounting seat 121 rotates by a certain angle along the first rotation direction a, the two ends of the first limiting member 124 will respectively abut against the mounting seat 121 and the connecting mechanism 120, preventing the mounting seat 121 from continuing to rotate in the first rotation direction a. After the mounting seat 121 rotates by a certain angle in the second rotation direction b, the two ends of the second limiting member 125 respectively abut against the mounting seat 121 and the connecting mechanism 120, preventing the mounting seat 121 from continuing to rotate in the second rotation direction b. After such a design, the mounting seat 121 can only rotate within a certain angle range, limiting the maximum limiting angle of the mounting seat 121, which can reduce the safety risk of the tooling sample rack 300, the vehicle door 2000, etc. accidentally hitting the operator due to the excessive rotation of the mounting seat 121 along the first rotation direction a caused by the failure of the adjusting member 140 to adjust, and reduce the safety risk of the tooling sample rack 300, the vehicle door 2000, etc. accidentally hitting the operator due to the excessive adjustment of the pitch angle α and the uncontrolled excessive rotation of the mounting seat 121 along the second rotation direction b. The safety performance of the connecting assembly 100 is higher.

[0076] In some embodiments, both the first limiting member 124 and the second limiting member 125 are connected to the mounting seat 121. After such a design, after the mounting seat 121 rotates by a certain angle along the first rotation direction a, the first limiting member 124 will abut against the connecting mechanism 120, preventing the mounting seat 121 from continuing to rotate along the first rotation direction a. After the mounting seat 121 rotates by a certain angle in the second rotation direction b, the second limiting member 125 will abut against the connecting mechanism 120, preventing the mounting seat 121 from continuing to rotate along the second rotation direction b, so that the mounting seat 121 can only rotate within a certain angle range.

[0077] In some embodiments, the first limiting member 124 is threadedly connected to the support mechanism 110 or the mounting seat 121; and / or, the second limiting member 125 is threadedly connected to the support mechanism 110 or the mounting seat 121.

[0078] The first limiting member 124 is threadedly connected to the support mechanism 110 or the mounting base 121. The second limiting member 125 is threadedly connected to the support mechanism 110 or the mounting base 121. After such design, by rotating the first limiting member 124, the length of the section of the first limiting member 124 between the support mechanism 110 and the mounting base 121 can be changed, so as to adjust the maximum angle of rotation of the mounting base 121 along the first rotation direction a. By rotating the second limiting member 125, the length of the section of the second limiting member 125 between the support mechanism 110 and the mounting base 121 can be changed, so as to adjust the maximum angle of rotation of the mounting base 121 along the second rotation direction b. The threaded connection enables the rotation amplitude of the mounting base 121 to be flexibly adjusted according to different requirements such as the tooling sample rack 300 and the vehicle door 2000, so that the connection assembly 100 can be applied to more scenarios.

[0079] In some embodiments, one ends of the first limiting member 124 and the second limiting member 125 close to the mounting base 121 are both threadedly connected to the mounting base 121. Threaded holes are formed in the mounting base 121, and the first limiting member 124 and the second limiting member 125 are installed in the threaded holes. By rotating the first limiting member 124, the relative position between the first limiting member 124 and the mounting base 121 can be changed, and further the length of the section of the first limiting member 124 between the support mechanism 110 and the mounting base 121 can be adjusted, so as to adjust the maximum angle of rotation of the mounting base 121 along the first rotation direction a. By rotating the second limiting member 125, the relative position between the second limiting member 125 and the mounting base 121 can be changed, and further the length of the section of the second limiting member 125 between the support mechanism 110 and the mounting base 121 can be adjusted, so as to adjust the maximum angle of rotation of the mounting base 121 along the second rotation direction b.

[0080] In some embodiments, the support mechanism 110 includes a support plate 111 and two ear plates 112 fixedly connected to the support plate 111. The two ear plates 112 are spaced along the Y direction, and the mounting base 121 is rotatably connected to the two ear plates 112.

[0081] In some embodiments, two first limiting members 124 and two second limiting members 125 are provided.

[0082] In some embodiments, the connection assembly 100 further includes a buffer 150, and the buffer 150 is installed on the connection mechanism 120 or the support mechanism 110; along the X direction, two ends of the buffer 150 respectively act on the connection mechanism 120 and the support mechanism 110.

[0083] The buffer 150 is installed on the connecting mechanism 120 or on the supporting mechanism 110. When multiple buffers 150 are provided, a part of the buffers 150 can be installed on the connecting mechanism 120 and another part of the buffers 150 can be installed on the supporting mechanism 110. The structure of the buffer 150 and its installation method are well known to those skilled in the art and will not be elaborated here. The buffer 150 can play a buffering role. By providing the buffer 150, the rotation speed of the connecting mechanism 120 can be adjusted, so that the connecting mechanism 120 can rotate at a slower speed, improving the safety performance of the connecting assembly 100.

[0084] In some embodiments, the buffer 150 is installed on the connecting mechanism 120, and the end of the buffer 150 away from the connecting mechanism 120 abuts against the supporting mechanism 110.

[0085] In some embodiments, two buffers 150 are provided. The buffers 150 are installed on the mounting seat 121. Along the Z direction, the buffers 150 are located below the rotating shaft of the connecting mechanism 120, and the adjusting member 140 is also provided below the rotating shaft of the connecting mechanism 120. After such a design, when the mounting seat 121 rotates in the first rotation direction a, under the action of the buffer 150, the rotation speed of the mounting seat 121 in the first rotation direction a slows down, preventing the door on the connecting mechanism 120 from rotating too fast, reducing the safety risk of the door accidentally hitting the operator, and the safety performance of the connecting assembly 100 is higher.

[0086] In some embodiments, the adjusting member 140 is a cylinder. The cylinder barrel of the cylinder is installed on the supporting mechanism 110, the piston rod of the cylinder abuts against the tooling sample rack 300, and the piston rod of the cylinder is arranged along the X direction.

[0087] As Figure 1 shown, based on the same inventive concept, the embodiment of the present application further provides a door installation device 1000, including a boosting arm 200, a connecting assembly 100 and a tooling sample rack 300. The supporting mechanism 110 of the connecting assembly 100 is connected to the boosting arm 200; the tooling sample rack 300 is connected to the connecting member 130 of the connecting assembly 100, and the tooling sample rack 300 is used for installing the door 2000.

[0088] Since the door installation device 1000 includes the above-mentioned connecting assembly 100, therefore, it naturally has all the beneficial effects of the connecting assembly 100 and will not be elaborated here.
