Abstract
Description
Technical Field
[0001] This invention relates to the field of automobile body manufacturing technology, and in particular to a component overlap error prevention device and component overlap method. Background Technology
[0002] In the design and manufacturing of automobile bodies, parts need to be joined together before welding. There are generally two types of joining: butt joints and planar joints. Planar joints are widely used in automobile body design because they can absorb accumulated tolerances. However, planar joints have the problem of easily leading to incorrect assembly sequence during assembly operations. Assembly errors will seriously affect the precision of the car body, directly causing assembly difficulties or even leading to the scrapping of the car body.
[0003] To avoid assembly sequence errors when parts overlap, existing solutions design error-proof flanges, bosses, or reinforcing ribs at the overlap points of the parts, with their direction facing the opposite direction of the two parts overlap points. However, the error-proof structure features are small and require visual identification by employees, who may overlook them, thus failing to meet the 100% error-proof requirement and potentially causing scrap. Moreover, the protrusions formed by the error-proof structure can affect sealing and aesthetics, making it impossible to implement in places where sealing is required.
[0004] Therefore, there is an urgent need for a component overlap error prevention device and component overlap method to solve the above problems. Summary of the Invention
[0005] The purpose of this invention is to provide a component overlap prevention device and component overlap method, which can prevent component assembly sequence errors during automobile body welding and assembly, thereby reducing component scrapping, and eliminates the need for error prevention structures on the components, ensuring the sealing and aesthetics of the overlap.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] A component overlap prevention device, comprising:
[0008] The base has an inclined end, and the inclined end has a guide groove along the extending direction;
[0009] The error-proof structure includes a first support member and a second support member. One end of the first support member is connected to one end of the second support member. The first support member and the second support member are set at an angle. A sliding member is provided at the connection between the first support member and the second support member. The sliding member is slidably disposed in the guide groove. The first support member is configured to support a first overlapping part, and the second support member is configured to support a second overlapping part.
[0010] When the first support member slides down to the first preset position, the second support member slides down to the second preset position, and the first overlapping part overlaps with the second overlapping part.
[0011] Optionally, a receiving groove is provided at the connection between the first support member and the second support member, and the sliding member is a ball bearing, with a portion of the ball bearing embedded in the receiving groove.
[0012] Optionally, the shape of the receiving groove matches the shape of the ball, and there is a gap between the receiving groove and the ball.
[0013] Optionally, a connecting shaft is provided at the connection between the first support member and the second support member, the sliding member is a pulley, the connecting shaft passes through the pulley, and the axis of the connecting shaft coincides with the axis of the pulley.
[0014] Optionally, the pulley is provided with an anti-slip layer along its circumference.
[0015] A method for joining parts, the method being based on the aforementioned error-proofing device for joining parts, the method comprising:
[0016] First, place the first overlapping part on the first support member, then slide the first support member down to the first preset position, and then slide the second support member down to the second preset position;
[0017] Then place the second overlapping part on the second support member, and the second overlapping part overlaps with the first overlapping part.
[0018] The beneficial effects of this invention are:
[0019] The component overlap prevention device provided by this invention, when the employee operates correctly, firstly places the first overlapping component on the first support member, the first support member slides down to the first preset position, the second support member slides down to the second preset position, and then places the second overlapping component on the second support member, at which point the second overlapping component overlaps with the first overlapping component. When the employee operates incorrectly, firstly places the second overlapping component on the second support member, the second support member slides up to the third preset position, the first support member slides up to the fourth preset position, and then places the first overlapping component on the first support member. At this point, there is a distance between the first and second overlapping components, and the first overlapping component does not overlap with the second overlapping component. The employee can easily visually observe the abnormality, thus prompting the employee to correct the incorrect assembly sequence and return to the correct operation. This component overlap prevention device and component overlap method can prevent incorrect assembly sequence of components during the welding and assembly of automobile bodies, thereby reducing component scrap, and eliminates the need for error prevention structures on the components, ensuring the sealing and aesthetics of the overlap.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.
[0034] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0035] like Figures 1 to 6As shown, this embodiment provides a component overlap anti-misalignment device, including a base 100 and an anti-misalignment structure 200. The base 100 is provided with an inclined end 110, and the inclined end 110 is provided with a guide groove 111 along the extension direction. The anti-misalignment structure 200 includes a first support member 210 and a second support member 220. One end of the first support member 210 is connected to one end of the second support member 220. The first support member 210 and the second support member 220 are arranged at an angle. A sliding member 230 is provided at the connection between the first support member 210 and the second support member 220. The sliding member 230 is slidably disposed in the guide groove 111. The first support member 210 is configured to support the first overlap part 10, and the second support member 220 is configured to support the second overlap part 20. When the first support member 210 slides downward to the first preset position, the second support member 220 slides downward to the second preset position, and the first overlapping part 10 overlaps with the second overlapping part 20; when the second support member 220 slides upward to the third preset position, the first support member 210 slides upward to the fourth preset position, and there is a distance between the first overlapping part 10 and the second overlapping part 20, and the first overlapping part 10 does not overlap with the second overlapping part 20. For example, the first support member 210 is perpendicular to the second support member 220.
[0036] The component overlap error prevention device provided in this embodiment, when the employee operates correctly, firstly places the first overlapping component 10 on the first support 210, the first support 210 slides down to the first preset position, the second support 220 slides down to the second preset position, and then places the second overlapping component 20 on the second support 220, at which point the second overlapping component 20 overlaps with the first overlapping component 10; when the employee operates incorrectly, firstly places the second overlapping component 20 on the second support 220, the second support 220 slides up to the third preset position, the first support 210 slides up to the fourth preset position, and then places the first overlapping component 10 on the first support 210. At this point, there is a distance between the first overlapping component 10 and the second overlapping component 20, and the first overlapping component 10 does not overlap with the second overlapping component 20. The employee can more easily visually observe the abnormality, thus prompting the employee to correct the assembly sequence error and return to the correct operation. This component overlap anti-misalignment device can prevent incorrect assembly sequence of components during the welding and assembly of automobile bodies, thereby reducing component scrap. Moreover, it eliminates the need to install anti-misalignment structures 200 on the components, ensuring the sealing and aesthetics of the overlap.
[0037] In some embodiments, a receiving groove 240 is provided at the connection between the first support member 210 and the second support member 220, and the sliding member 230 is a ball bearing 231. A portion of the ball bearing 231 is embedded in the receiving groove 240. By providing the receiving groove 240, the ball bearing 231 can be limited to prevent it from dislodging from the connection between the first support member 210 and the second support member 220, and the ball bearing 231 can move relative to the guide groove 111. Exemplarily, the shape of the receiving groove 240 matches the shape of the ball bearing 231, and there is a gap between the receiving groove 240 and the ball bearing 231, so that the ball bearing 231 can roll relative to the receiving groove 240, ensuring that the ball bearing 231 can roll smoothly.
[0038] In other embodiments, a connecting shaft 250 is provided at the connection between the first support member 210 and the second support member 220, and a sliding member 230 is a pulley 232. The connecting shaft 250 passes through the pulley 232, and the axis of the connecting shaft 250 coincides with the axis of the pulley 232. During movement, the pulley 232 can rotate relative to the connecting shaft 250, thereby enabling the pulley 232 to move within the guide groove 111. For example, the pulley 232 is provided with an anti-slip layer along its circumference, thereby increasing the friction between the pulley 232 and the guide groove 111, allowing the pulley 232 to rotate more effectively relative to the connecting shaft 250. To avoid interference between the connection between the first support member 210 and the second support member 220 and the pulley 232, a groove 260 is provided at the connection between the first support member 210 and the second support member 220. A portion of the pulley 232 is located within the groove 260, and a gap exists between the pulley 232 and the groove 260.
[0039] This embodiment also provides a component overlap method, which is based on the component overlap error prevention device provided in the above embodiment. The component overlap method includes: firstly placing the first overlap component 10 on the first support member 210, the first support member 210 sliding down to the first preset position, and the second support member 220 sliding down to the second preset position; then placing the second overlap component 20 on the second support member 220, and the second overlap component 20 overlaps with the first overlap component 10.
[0040] Since the component overlapping method is based on the component overlapping error prevention device, it will inevitably have the technical effects described above, which will not be repeated here.
[0041] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
