Description

Technical Field

[0001] The invention belongs to the technical field of automated equipment manufacturing, and in particular relates to an electric flipping mechanism for the overall assembly of a vehicle side panel. Background Art

[0002] At present, the automobile side panel assembly flipping mechanism is composed of a sliding part, a flipping part, and a side fan clamp part, of which the flipping part is driven by two sets of standard cylinders. Its action process can be simply summarized as follows:

[0003] 1. After the side sash clamp is opened, the slide mechanism with the clamp returns to the specified stroke;

[0004] 2. After the slide returns to its position, the locking cylinder is locked, and the standard cylinder of the flip part is extended to flip the side fan clamp upward 90 degrees;

[0005] 3. After flipping into place, pick up the upper parts of the side enclosure, and clamp the panels after they are in place;

[0006] 4. The standard cylinder of the flipping part is retracted to flip the side fan fixture with the plate back 90 degrees;

[0007] 5. The slide table extends out to drive the side fan fixture to move forward to the working position as a whole, and then it is assembled with the lower car body and the top cover cross beam to start welding;

[0008] 6. After welding is completed, open the side fan clamp and repeat the above process.

[0009] Since the driving force required for the side fan flipping is large, the cylinder diameter will also be relatively large, resulting in a large fixture structure with poor stability. It may also cause jamming, insufficient pressure to lift the side fan fixture, etc.; and unstable air pressure will reduce the fixture flipping speed, thereby affecting the beat and reducing car production. Summary of the invention

[0010] In order to effectively solve the problems in the above-mentioned background technology, the present invention proposes an electric flipping mechanism for the overall assembly of the side panel of an automobile.

[0011] The specific technical solutions are as follows:

[0027] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways, rotated 90 degrees or in other orientations, and the spatially relative descriptions used herein are interpreted accordingly.

[0028] The specific implementation of the present invention is described in detail below with reference to the accompanying drawings and preferred embodiments.

[0029] See also Figure 1 , an electric flip mechanism for the overall assembly of a vehicle side panel, comprising a motor drive part 1, a cylinder locking mechanism 2, a manual locking mechanism 3 and a rotating shaft mechanism 4, wherein the motor drive part is used to drive the rotating shaft mechanism to rotate, the rotating shaft mechanism is connected to the side fan clamp, the pneumatic locking mechanism is used to lock the rotating shaft mechanism in place, and the manual locking mechanism is used to lock the rotating shaft mechanism in place. Figure 2 As shown, the motor drive part includes a base 11, a motor and a reducer 12, a coupling 13, a bearing seat 14, a rotating shaft 15 and a rotating frame 16. The motor and the reducer are installed on the base, the motor and the reducer are connected to the rotating shaft through a coupling, the rotating shaft is installed on the base through a bearing seat, the rotating frame is fixed on the rotating shaft, and the side sash clamp is fixed on the rotating frame. This part is the priority driving source for the side sash to flip.

[0030] like Figure 3As shown, specifically, the cylinder locking mechanism 2 includes a clamping cylinder 21 and a clamping block 22. The clamping cylinder is fixed on the base, and the clamping block is fixed on the side of the rotating frame. The clamping cylinder cooperates with the clamping block. When the side sash base rotates to the right position, the limit block connected to the base hits the fixed limit block of the cylinder locking structure, and the cylinder drives the other half of the limit block to press, ensuring that the side sash will not deviate.

[0031] like Figure 4 and Figure 5 As shown, specifically, the manual locking mechanism includes a handle 31, a handle base 32, a sleeve 33, a positioning shaft 34, a shield 35 and a travel switch 36. The handle base is fixed on the bearing seat, the handle is fixedly connected to the side of the positioning shaft, the sleeve is fixed in the handle base, the positioning shaft and the sleeve are slidably matched, the side of the rotating frame is provided with a positioning hole, the positioning shaft is matched with the positioning hole, the shield is fixed on the handle base, and the travel switch is arranged on the side of the handle base for detecting the position of the positioning shaft. When the side leaf clamp needs to be stopped for maintenance, the worker must operate the manual locking part to ensure safety; the handle drives the positioning shaft to extend and pass through the hole of the side leaf base, and the travel switch is in working state and has signal output.

[0032] like Figure 6 As shown, specifically, it also includes a cylinder driving part 5, which includes a standard cylinder 51, a cylinder connecting lock 52 and a cylinder seat 53. The standard cylinder is installed on the cylinder seat, and the piston rod of the standard cylinder is hinged to one end of the cylinder connecting lock, and the other end of the cylinder connecting lock is fixed to the rotating shaft. This part is a backup driving solution for the side fan flipping.

[0033] Working principle: PLC sends out a command, the servo motor drives the side fan fixture to flip 90 degrees to the receiving plate position, PI CKUP releases the parts, and after the detection switch on the fixture receives the plate in place signal, the side fan fixture is partially clamped, and the servo motor drives the side fan fixture to flip back 90 degrees to the loading direction. The cylinder drive part is used as a temporary solution when the motor is damaged and cannot be used. The action principle is the same as that of the servo motor drive. The role of the cylinder locking mechanism is that the overall structure and weight of the side fan fixture are relatively large. When it is flipped into place, a limit block is required to ensure the accuracy of each time in place. In this way, it is necessary to add a cylinder locking mechanism, one at the front and one at the back, and one at the connection state and the loading state. The role of the manual locking mechanism is that when some parts on the side fan fixture or the slide fixture need to be repaired, the gas and power will be cut off. In order to ensure that the structure will not shake suddenly when the worker is repairing and cause safety hazards, it is necessary to manually extend the pin to lock the side fan fixture. This mechanism is similar to the role of the cylinder locking mechanism. The role of the rotating shaft structure is to design multiple rotating support points to increase the stability of the structure.

[0034] It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
