Description

Technical Field

[0001] This utility model belongs to the field of automotive sheet metal welding positioning technology, and in particular relates to a rapid positioning fixture and welding workstation for automotive sheet metal welding. Background Technology

[0002] With the continuous development of the automotive industry, the requirements for automobile production efficiency and quality are increasing. As a crucial component of the automobile body, the welding quality of sheet metal parts directly affects the overall strength, safety, and appearance of the vehicle. In large-scale automobile production, a tooling system capable of quickly and accurately positioning sheet metal parts is needed to improve welding efficiency and quality, meeting the high-efficiency production demands of the automotive manufacturing industry.

[0003] In the process of positioning automotive sheet metal parts, it is often necessary to position multiple sheet metal parts of the same type. Usually, only one positioning fixture is set for the same type of sheet metal parts. Therefore, the existing positioning fixture can only position one sheet metal part at a time. While the previous sheet metal part is being positioned, the other sheet metal parts can only wait. Obviously, the positioning efficiency is low and cannot meet the requirements of fast-paced production. Utility Model Content

[0004] The purpose of this utility model is to provide a rapid positioning fixture and welding workstation for automotive sheet metal parts, so as to solve the problem of low positioning efficiency of conventional positioning fixtures in the prior art.

[0005] To achieve this objective, the present invention adopts the following technical solution:

The plurality of second positioning elements form a positioning area for positioning the side of the sheet metal part to be welded.

[0009] The second positioning component is disposed on one side of the support platform. The second positioning component is configured to press against the end face of the sheet metal part to be welded when the sheet metal part to be welded is placed on the support platform, thereby cooperating with the support platform, the first positioning component and the plurality of second positioning components to fix the sheet metal part to be welded.

[0010] Furthermore, the positioning mechanism also includes a detection component, which is disposed on the positioning seat and configured to detect whether a nut is pre-installed on the sheet metal part to be welded when the sheet metal part to be welded is placed on the support platform.

The flipping drive is configured to drive the flipping component to flip to the first position or the second position.

[0013] The flipping drive drives the flipping component to flip to the second position, so that the second end of the flipping component presses against the end face of the sheet metal part to be welded, thereby fixing the sheet metal part to be welded.

[0014] The flipping drive drives the flipping component to flip to the first position, so that the second end of the flipping component moves away from the sheet metal part to be welded, thereby releasing the positioning of the sheet metal part to be welded.

[0015] Furthermore, the middle part of the flipping component is hinged to the end face of the flipping drive component via a hinge assembly. The hinge assembly includes a hinge seat and a hinge rod. The bottom of the hinge seat is mounted on the end face of the flipping drive component. The first end of the hinge rod is hinged to the top of the hinge seat, and the second end of the hinge rod is hinged to the middle part of the flipping component.

[0016] Furthermore, the positioning mechanism also includes a lifting assembly, the support platform is movably mounted on the positioning seat, the drive end of the lifting assembly is connected to the support platform, and the lifting assembly is configured to drive the support platform to a high position or a low position.

[0017] The lifting assembly drives the support platform to a high position, and the support platform supports the sheet metal part to be welded at the high position;

[0018] The lifting assembly drives the support platform to a low position, thereby moving the welded sheet metal parts to a low position.

[0021] Compared with existing technologies, the advantages of the aforementioned rapid positioning fixture and welding workstation for automotive sheet metal parts are as follows:

[0022] 1) By setting at least two sets of positioning mechanisms on the base, and through the cooperation of the first positioning component and the second positioning component, the first positioning component positions the bottom of the sheet metal part to be welded, and multiple second positioning components form a positioning area for positioning the side of the sheet metal part to be welded. The second positioning component presses against the end face of the sheet metal part to be welded, and together with the bearing platform, the first positioning component and multiple second positioning components fix the sheet metal part to be welded, thus realizing that at least two sheet metal parts to be welded can be positioned at one time, which greatly improves the positioning efficiency.

[0023] 2) By setting up a detection component, it is possible to detect whether nuts are pre-installed on the sheet metal parts to be welded when they are placed on the support platform, which simplifies the welding process and improves the efficiency of subsequent welding.

[0033] Firstly, a quick positioning fixture for welding automotive sheet metal parts is provided; please refer to [link / reference]. Figures 1 to 5 As shown, in this embodiment, a rapid positioning fixture for welding automotive sheet metal parts includes a base 10 and at least two sets of positioning mechanisms 20 disposed on the base 10. Each positioning mechanism 20 includes a positioning seat 30, a first positioning component 40, and a second positioning component 50. A support platform 31 is disposed on the positioning seat 30, and the support platform 31 is configured to support the sheet metal part 11 to be welded. The first positioning component 40 includes a first positioning element 41 and multiple second positioning elements 42. The first positioning element 41 is vertically mounted on the positioning seat 30 and its top extends beyond the support surface of the support platform 31. The top of the first positioning element 41 is positioned relative to the bottom of the sheet metal part 11 to be welded. The positioning holes 12 are adapted to each other. The first positioning member 41 is configured to position the bottom of the sheet metal part 11 to be welded through the positioning holes 12. Multiple second positioning members 42 are evenly distributed vertically upward on the bearing surface of the bearing platform 31. The multiple second positioning members 42 form a positioning area for positioning the side of the sheet metal part 11 to be welded. The second positioning component 50 is disposed on one side of the bearing platform 31. The second positioning component 50 is configured to press against the end face of the sheet metal part 11 to be welded when the sheet metal part 11 to be welded is placed on the bearing platform 31, thereby cooperating with the bearing platform 31, the first positioning member 41 and the multiple second positioning members 42 to fix the sheet metal part 11 to be welded.

[0034] Specifically, the first positioning component 41 is a positioning pin, and the second positioning component 42 is a positioning plate or positioning block that is vertically installed on the support platform 31.

[0035] As one implementation method, this embodiment is provided with two sets of positioning mechanisms 20. Of course, the number of positioning mechanisms 20 can be set according to the number of sheet metal parts 11 to be welded.

[0036] It should be noted that the sheet metal part 11 to be welded includes a first side plate 110, two second side plates 111, and a bottom plate 112. The first ends of the two second side plates 111 are connected to the bottom plate 112, and the second ends of the two second side plates 111 are bent toward the first side plate 110 and abut against the first side plate 110. The contact area 114 between the two second side plates 111 and the first side plate 110 is the welding area. The bottom plate 112 is provided with a positioning hole 12 and a nut 13 is pre-installed on one side of the positioning hole 12. A clearance hole 113 is provided on the bottom plate 112 corresponding to the nut 13. During positioning, the first side plate 110 and the two second side plates 111 abut against the second positioning member 42 and are located in the positioning area surrounded by multiple second positioning members 42.

[0037] As can be seen, by setting at least two sets of positioning mechanisms 20 on the base 10, and through the cooperation of the first positioning component 40 and the second positioning component 50, the first positioning component 41 positions the bottom of the sheet metal part 11 to be welded, and multiple second positioning components 42 form a positioning area for positioning the side of the sheet metal part 11 to be welded. The second positioning component 50 presses against the end face of the sheet metal part 11 to be welded, and in conjunction with the bearing platform 31, the first positioning component 41 and multiple second positioning components 42 fix the sheet metal part 11 to be welded, thereby realizing that at least two sheet metal parts 11 to be welded can be positioned at one time, which greatly improves the positioning efficiency.

[0038] In one embodiment, the positioning mechanism 20 also includes a detection component 60, which is disposed on the positioning seat 30 and is configured to detect whether a nut 13 is pre-installed on the sheet metal part 11 to be welded when the sheet metal part 11 to be welded is placed on the support platform 31.

[0039] As can be seen, by setting up the detection component 60, it is possible to detect whether the nut 13 is pre-installed on the sheet metal part 11 to be welded when it is placed on the support platform 31, which simplifies the welding process and improves the efficiency of subsequent welding.

[0040] In one embodiment, the detection assembly 60 includes a detection frame 61 and a sensor 62. The detection frame 61 is mounted on the bottom of the positioning seat 30, and the bottom of the sensor 62 is mounted on the detection frame 61. The top of the sensor 62 extends out of the clearance hole 113 on the bearing surface of the bearing platform 31 and is adapted to the position of the pre-installed nut 13 on the sheet metal part 11 to be welded.

[0041] Of course, as another implementation, the middle part of the sensor 62 can also be directly installed in the clearance hole 113 of the bearing surface of the bearing platform 31, and the top of the sensor 62 extends out of the bearing surface.

[0042] Specifically, sensor 62 is a type of displacement sensor or proximity switch.

[0043] As can be seen, by cooperating the detection frame 61 and the sensor 62, the top of the sensor 62 extends out of the bearing surface of the bearing platform 31 and is adapted to the position of the pre-installed nut 13 on the sheet metal part 11 to be welded, so that the detection of whether the nut 13 is pre-installed can be carried out when the sheet metal part 11 to be welded is placed, and a detection component 60 with small space occupation and high detection efficiency is provided.

[0044] In one embodiment, the second positioning component 50 includes a positioning frame 51, a flipping drive 52, and a flipping component 53. The positioning frame 51 is vertically mounted on the base 10 and located on one side of the positioning seat 30. The flipping component 53 can be flipped to a first position or a second position. The fixed end of the flipping drive 52 is mounted on the top of the positioning frame 51, and the driving end of the flipping drive 52 is connected to the first end of the flipping component 53. The flipping drive 52 is configured to drive the flipping component 53 to flip to the first position or the second position. The flipping drive 52 drives the flipping component 53 to flip to the second position, so that the second end of the flipping component 53 presses against the end face of the sheet metal part 11 to be welded, thereby fixing the sheet metal part 11 to be welded. The flipping drive 52 drives the flipping component 53 to flip to the first position, so that the second end of the flipping component 53 moves away from the sheet metal part 11 to be welded, thereby releasing the positioning of the sheet metal part 11 to be welded.

[0045] Specifically, the tilting drive component 52 is a drive cylinder.

[0046] As can be seen, through the cooperation of the flipping drive 52 and the flipping component 53, the flipping drive 52 drives the flipping component 53 to flip to the second position, so that the second end of the flipping component 53 presses against the end face of the sheet metal part 11 to be welded, thereby fixing the sheet metal part 11 to be welded. This achieves the positioning of the sheet metal part 11 to be welded on the support platform 31 by rotation, and provides a second positioning component 50 that is easy to implement and has a good fixing effect.

[0047] In one embodiment, the middle part of the flipping member 53 is hinged to the end face of the flipping drive member 52 via a hinge assembly 54. The hinge assembly 54 includes a hinge seat 540 and a hinge rod 541. The bottom of the hinge seat 540 is mounted on the end face of the flipping drive member 52, the first end of the hinge rod 541 is hinged to the top of the hinge seat 540, and the second end of the hinge rod 541 is hinged to the middle part of the flipping member 53.

[0048] As can be seen, the hinge seat 540 and the hinge rod 541 cooperate to realize the rotational control of the flipping drive 52 on the flipping component 53, which not only facilitates fixation but also has high transmission efficiency.

[0049] In one embodiment, the positioning mechanism 20 also includes a lifting assembly 70. The support platform 31 is movably mounted on the positioning seat 30. The drive end of the lifting assembly 70 is connected to the support platform 31. The lifting assembly 70 is configured to drive the support platform 31 to a high position or a low position. The lifting assembly 70 drives the support platform 31 to a high position, where the support platform 31 supports the sheet metal part 11 to be welded. The lifting assembly 70 drives the support platform 31 to a low position to move the welded sheet metal part to a low position.

[0050] As can be seen, by setting up the lifting component 70, the lifting component 70 drives the support platform 31 to the low position, thereby driving the welded sheet metal parts to the low position, which facilitates the subsequent manual or handling equipment to transfer the welded sheet metal parts to the subsequent work station.

[0051] In one embodiment, the lifting assembly 70 includes a lifting drive 71 and a lifting member 72. The lifting member 72 is movably mounted on the positioning seat 30. The support platform 31 is mounted on the lifting member 72. The fixed end of the lifting drive 71 is mounted on the positioning seat 30. The driving end of the lifting drive 71 is connected to the lifting member 72. The lifting drive 71 is configured to drive the lifting member 72 to move up and down, thereby driving the support platform 31 to move up and down.

[0052] Specifically, the lifting drive component 71 can be an electric cylinder, a pneumatic cylinder, or other linear module with similar functions.

[0053] Secondly, based on the aforementioned rapid positioning fixture for welding automotive sheet metal parts, a welding workstation is provided. The welding workstation includes a welding robot and the aforementioned rapid positioning fixture for welding automotive sheet metal parts. The welding robot is disposed on one side of the base 10 and is configured to perform welding on the positioned sheet metal part 11 to be welded.

[0054] During the positioning process of the aforementioned rapid positioning fixture for welding automotive sheet metal parts: First, a person or a robot places the sheet metal part 11 to be welded on the support platform 31, and the first positioning component 41 passes through the positioning hole 12 to position the bottom of the sheet metal part 11 to be welded. At the same time, the side of the sheet metal part 11 to be welded abuts against multiple second positioning components 42. The side of the sheet metal part 11 to be welded is positioned by the multiple second positioning components 42. The sensor 62 detects whether the nut 13 is pre-installed on the sheet metal part 11 to be welded; Second... When the sheet metal part 11 to be welded is placed on the support platform 31, the second positioning component 50 presses against the end face of the sheet metal part 11 to be welded, thereby fixing the sheet metal part 11 to be welded. Then, the welding robot welds the contact area 114 between the two second side plates 111 and the first side plate 110 of the fixed sheet metal part 11 to be welded. Finally, the lifting component 70 drives the support platform 31 to a low position, thereby moving the welded sheet metal part to a low position. The welded sheet metal part is then transferred to the subsequent processing station by a person or a robot.
