Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile body transportation equipment, and particularly relates to a side wall carrying mechanism and a carrying and assembling device. BACKGROUND

[0002] The automobile body side wall is a large stamping part. In the automobile production process, the automobile body side wall needs to be carried and assembled on a clamp for welding. When engineering is set, both the robot welding accessibility and the manual assembly workability need to be considered. In order to meet the robot welding requirements, the clamp needs to be kept horizontally at about 0°. For large parts such as the automobile body side wall, how to make it easier for the manual assembly, the clamp needs to be kept at about 60° with the ground, and then the automobile body side wall is vertically placed on the clamp, so that the worker can more easily assemble.

[0003] For the conversion of the two different postures, the commonly used method is to make a reversible clamp or to add a transfer carrying robot for conversion. First, the clamp reversing method occupies more welding time because the manual installation of large parts and the clamp reversing and assembly welding are set in the same process, so the production cycle time is too long, the production efficiency is low, and it is not suitable for scenes with fast production rhythm requirements. Second, for production lines with fast production rhythm requirements, the process is often split and a carrying robot is added for transfer, but due to the increase of the robot, the required land and investment are also relatively high.

[0004] Therefore, it is necessary to provide a new side wall carrying mechanism and carrying and assembling device to solve or at least alleviate the above technical defects. SUMMARY

[0005] The main purpose of the present application is to provide a side wall carrying mechanism and carrying and assembling device, which aims to solve the technical problems of low production efficiency and high cost in the prior art.

[0010] A clamping assembly is rotatably mounted on the bottom of the main frame, and is used to accommodate the rocker portion of the automobile body side wall.

[0011] In an embodiment, the clamping assembly comprises a clamping driving member and a bearing portion, the first position of the bearing portion is hinged to the main frame, the bearing portion and the main frame jointly form an accommodating groove, the second position of the bearing portion is hinged to the output shaft of the clamping driving member, the body of the clamping driving member is hinged to the main frame, and the clamping driving member is used to drive the bearing portion to rotate relative to the main frame.

[0012] In an embodiment, the mounting frame is formed with a groove on the side facing the support frame, and the output shaft of the lifting driving member is connected to the bottom of the groove.

[0014] In an embodiment, the side wall carrying mechanism further comprises a plurality of positioning blocks, and the positioning blocks are arranged on the main frame at intervals, and the end of the positioning block away from the main frame is used to abut against the automobile body side wall.

[0015] In an embodiment, the side wall carrying mechanism further comprises a sensor, and the sensor is mounted on the main frame.

[0016] In an embodiment, the base is formed with two oppositely arranged guide grooves, and the two ends of the support frame are respectively and correspondingly connected to the two guide grooves in a sliding manner.

[0017] In an embodiment, the translation driving member is a long-stroke air cylinder.

[0018] In an embodiment, the number of clamping assemblies is two, and the clamping assemblies are arranged at intervals.

[0020] In an embodiment, the assembling clamp mechanism is arranged above the translation driving member.

[0021] In the technical scheme, the side wall carrying mechanism has five movement states. First, in the initial position, the main frame is arranged in an inclined manner, specifically, at an angle of 60° with the horizontal plane, so as to facilitate the operator to carry the automobile body side wall to the main frame. Specifically, the operator installs the automobile body side wall by using a lifting tool.

[0039] Compared with the structure that the assembly clamp mechanism 200 is arranged to be overturnable, the embodiment reduces the occupation of the production rhythm of the assembly clamp mechanism 200, and can improve the work efficiency. Compared with the scheme of increasing the carrying robot, the embodiment occupies a smaller space and has a relatively low cost. In summary, the embodiment has the workpiece carrying and automatic assembly functions, is suitable for the manual installation automobile body side wall 110 production line, and has the advantages of small occupation, low cost and high efficiency.

[0040] The translation assembly 1, the lifting assembly 2, the overturning assembly 3 and the clamping assembly 4 can be in communication connection with a controller respectively, the controller can be a PLC (Programmable Logic Controller), and the automation control of the side wall carrying mechanism 100 can be realized by programming the PLC. The lifting driving part 22 is a telescopic cylinder, which can be a hydraulic cylinder or a pneumatic cylinder. In the embodiment, the lifting driving part 22 is a pneumatic cylinder.

[0041] It should be noted that the workpiece in the present application is not limited to the automobile body side wall 110, and other large workpieces or similar workpieces that need to be converted in posture can also be used.

[0042] Referring to Figure 2 In an embodiment, the clamping assembly 4 comprises a clamping driving part 41 and a bearing part 42. The first position of the bearing part 42 is hinged to the main frame 33, and the bearing part 42 and the main frame 33 form an accommodating groove 43.

The clamping driving part 41 is used to drive the bearing part 42 to rotate relative to the main frame 33. The first position and the second position of the bearing part 42 are only used to represent the different positions of the hinge points of the bearing part 42 and the main frame 33 and the hinge points of the connecting part and the clamping driving part 41.

The turnover driving member 32 can also be a cylinder, and the turnover driving member 32 is used to drive the main body frame 33 to turn to an inclined state or a horizontal state, and the inclined state is mainly to adapt to manual assembly, and the horizontal state is to meet the requirements of robot assembly welding.

[0045] With reference to Figure 4 In an embodiment, a side of the mounting rack 31 facing the support frame 21 is formed with a recess 311, and the output shaft of the lifting driving member 22 is connected to the bottom of the recess 311. When the mounting rack 31 is at the lowest position, the lifting driving member 22 is partially accommodated in the recess 311, which can save the installation space of the lifting driving member 22, so that the overall structure is more compact and occupies less space.

[0046] With reference to Figure 5 In an embodiment, the side wall carrying mechanism 100 further comprises a plurality of guide rods 51, which are arranged on the main body frame 33 at intervals, and the side of each guide rod 51 is used to abut against the automobile body side wall 110.

[0049] With reference to Figure 3In an embodiment, the base 11 is formed with two oppositely arranged guide grooves 111, and the two ends of the support frame 21 are respectively and one-to-one slidably connected with the two guide grooves 111. The length direction of the guide grooves is consistent with the length direction of the translation driving member 12, and the installation space of the support frame 21 is between the two guide grooves 111, and then the lifting driving member 22, the overturning assembly 3 and the clamping assembly 4 are sequentially arranged on the support frame 21. The guide grooves play a limiting and guiding role, the support frame 21 cooperates with the two guide grooves to slide, and the running movement of the support frame 21 is more stable. The translation driving member 12 is a long-stroke air cylinder, which cooperates with the guide grooves 111 to drive the support frame 21 to move.

[0051] With reference to Figure 1 and Figure 3 In an embodiment, the assembling clamp mechanism 200 is arranged above the translation driving member 12. The assembling clamp mechanism 200 is limited by the running distance of the long-stroke air cylinder and the guide grooves 111, and therefore needs to be within the running range of the translation assembly 1, and arranging the assembling clamp mechanism 200 above the translation driving member 12 can shield and not interfere with the arrangement of the translation driving member 12, and the space utilization rate is high.

[0052] The above are only preferred embodiments of the present application, and do not limit the patent scope of the present application, and any equivalent structural transformation made under the inventive concept of the present application, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
