Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, and in particular to a multi-clamp gripping device and welding production line. Background Technology

[0002] In the automobile production process, cars need to be transported to the next process for welding. To improve work efficiency, fully automated welding production lines are currently used. With the diversification of car models, different fixtures are needed to transport different car model frames to the next workstation for welding. A currently published Chinese patent (CN216802202U) describes an automatic fixture switching system for multiple car models suitable for MPV assembly workstations. This system includes a frame with a left, middle, and right storage compartment. The left storage compartment includes a fixture limiting structure and a fixture conveying structure, with the conveying structure including a fixture transport trolley. This solution uses the left, middle, and right storage compartments to install fixtures, resulting in fewer fixture installation positions and a larger footprint. It cannot achieve rapid fixture switching, nor can it accommodate the clamping of different car model frames, requiring frequent fixture changes during the clamping process. Utility Model Content

[0003] In view of this, the present invention proposes a multi-clamp gripping device and welding production line, which solves the problems of insufficient clamp installation positions, large footprint, and inability to achieve the function of quick clamp switching.

[0004] The technical solution of this utility model is implemented as follows: This utility model provides a multi-clamp gripping device, including a rotating assembly, a mounting frame, clamp picking components, and clamps. The mounting frame is disposed on the top of the rotating assembly, and multiple clamp picking components are arranged circumferentially along the mounting frame. The clamps include a mounting plate and clamping arms, and multiple clamping arms are disposed around the mounting plate. The mounting plate is detachably mounted on the multiple clamp picking components. The rotating assembly includes a rotary table and a polygonal chassis. The mounting frame is disposed on the top of the polygonal chassis, and the polygonal chassis is disposed on the top of the rotary table. The polygonal chassis is rotatably connected to the rotary table.

[0005] Based on the above technical solutions, preferably, the clamping pickup assembly includes a pickup frame, a hook pin component, and a clamping component. Multiple pickup frames are arranged on the mounting frame, the hook pin component is arranged on the top of the pickup frame, and the clamping component is arranged on the bottom of the pickup frame. The clamp is fixed to the pickup frame by the hook pin component at the top of the pickup frame and the clamping component at the bottom of the pickup frame.

[0006] Based on the above technical solutions, preferably, the clamping component includes two clamping cylinders, which are respectively disposed at both ends of the bottom of the pickup frame.

[0007] Based on the above technical solutions, preferably, the rotating assembly further includes a locking component, which includes a locking groove and an automatic locking bolt. A plurality of the locking grooves are disposed at the bottom of the polygonal chassis, and the automatic locking bolt is disposed on the rotary table. The locking grooves cooperate with the automatic locking bolts.

[0008] Based on the above technical solutions, preferably, the rotating assembly further includes a detection component, which is disposed on the rotary table and electrically connected to the rotary table. The detection component is used to detect the model of the vehicle.

[0009] More preferably, the polygonal chassis includes a hexagonal chassis.

[0010] More preferably, the mounting bracket includes a hexagonal mounting bracket.

[0011] This application also relates to a welding production line, including the aforementioned multi-clamp gripping device and multi-vehicle model conveying device, wherein the multi-clamp gripping device is used to clamp and transport the car frames on the multi-vehicle model conveying device to the work point.

[0012] More preferably, the multi-vehicle conveying device includes a slide table, and tooling fixtures, a fixture conveying table and a robot gripping component arranged sequentially on the slide table.

[0013] Compared with the prior art, the present invention has the following beneficial effects: (1) By setting multiple clamp picking components and clamps, multiple clamp picking components can be used to install multiple different types of clamps to suit different vehicle models, so that different models of clamps can be installed on the same mounting bracket, increasing the installation position of clamps and greatly reducing the floor space.

[0014] (2) By setting up detection components to detect different models of car frames on the production line, the detection signal can be quickly transmitted to the rotating component, and the rotating component rotates to the corresponding matching fixture for clamping.

[0015] (3) By setting a locking component, when the corresponding clamp is rotated, the automatic locking bolt automatically pushes up and inserts into the locking groove, quickly locking and positioning the rotating component, preventing the clamp from shifting when clamping the car, making it impossible to accurately position and affecting the efficiency of use.

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0020] like Figure 1 As shown, a multi-clamp gripping device of this utility model includes a rotating assembly 1, a mounting frame 2, clamp picking components 3, and clamps 4. The mounting frame 2 is disposed on the top of the rotating assembly 1, and a plurality of clamp picking components 3 are arranged circumferentially along the mounting frame 2. The clamps 4 include a mounting plate 41 and clamping arms 42, and a plurality of clamping arms 42 are disposed around the mounting plate 41. The mounting plate 41 is detachably mounted on the plurality of clamp picking components 3. The rotating assembly 1 includes a rotary table 11 and a polygonal chassis 12. The mounting frame 2 is disposed on the top of the polygonal chassis 12, and the polygonal chassis 12 is disposed on the top of the rotary table 11. The polygonal chassis 12 is rotatably connected to the rotary table 11.

[0021] When the rotating component 1 rotates, it will drive the mounting bracket 2 to rotate, and at the same time, it will drive the clamping component 3 and the clamp 4 on the mounting bracket 2 to rotate. When the rotating component 1 recognizes the corresponding vehicle model, it will rotate to the corresponding clamp 4 and then stop to prepare for clamping operations.

[0022] The rotary table 11 can be precisely positioned in multiple stations. For example, it can achieve rotation in 6 fixed stations (60° angular intervals) through a hexagonal chassis. The rotary table 11 provides rotational power to the polygonal chassis 12. After the rotary table 11 starts working, it will drive the polygonal chassis 12 to rotate until it reaches the required position and then stops.

[0023] In some embodiments, such as Figure 2 As shown, the rotating assembly 1 also includes a locking component 13, which includes a locking groove 132 and an automatic locking bolt 131. A plurality of locking grooves 132 are disposed at the bottom of the polygonal chassis 12, and the automatic locking bolt 131 is disposed on the rotary table 11. The locking grooves 132 cooperate with the automatic locking bolt 131.

[0024] The locking component 13 has an upward structure. When the rotating component 1 rotates to the corresponding clamp 4, it will automatically stop rotating to prevent the polygonal chassis 12 from shaking due to lack of locking and fixation in subsequent operations, which would affect subsequent operations. Therefore, when the rotating component 1 drives the clamp picking component 3 on the mounting frame 2 to rotate to the corresponding position, the automatic locking bolt 131 will pop up and insert into the corresponding locking groove 132 to limit and fix it, preventing shaking and displacement.

[0025] In some embodiments, such as Figure 3 As shown, the clamping pickup assembly 3 includes a pickup frame 31, a hook pin component 32, and a clamping component 33. Multiple pickup frames 31 are arranged on the mounting frame 2. The hook pin component 32 is arranged on the top of the pickup frame 31, and the clamping component 33 is arranged on the bottom of the pickup frame 31. The clamp 4 is fixed to the pickup frame 31 by the hook pin component 32 at the top of the pickup frame 31 and the clamping component 33 at the bottom of the pickup frame 31.

[0026] The clamping component 33 includes two clamping cylinders 331, which are respectively located at both ends of the bottom of the pickup frame 31.

[0027] Different specifications and models of clamps 4 are used to clamp different car models. Different specifications and models of clamps 4 are set on clamping pickup components 3 at different angles. The top of the clamp 4 is fixed by the hook pin component 32 at the top of the pickup frame 31, and the bottom of the clamp 4 is fixed by the clamping and locking cylinders 331 at both ends of the bottom of the pickup frame 31.

[0028] In some embodiments, the rotating assembly 1 further includes a detection component 14, which is disposed on the rotary table 11 and electrically connected to the rotary table 11. The detection component 14 is used to detect the model of the vehicle.

[0029] The detection component 14 can detect the vehicle models conveyed by the multi-vehicle conveying device 5 and transmit the detected vehicle model signal to the rotary table 11. After receiving the signal, the rotary table 11 matches the model of the clamp 4 on the mounting bracket 2, starts the rotary table 11 to rotate to the corresponding clamp 4 mounting position, and clamps the car to the next process. The operation is repeated to complete the clamping work of different models of cars on the production line.

[0030] In some embodiments, the polygonal chassis 12 includes a hexagonal chassis, and the mounting bracket 2 includes a hexagonal mounting bracket 2.

[0031] like Figure 4 As shown, this application also relates to a welding production line, including the above-mentioned multi-clamp gripping device and multi-vehicle model conveying device 5, wherein the multi-clamp gripping device is used to clamp and transport the cars on the multi-vehicle model conveying device 5 to the work point.

[0032] The multi-vehicle conveying device 5 includes a slide table 51, and a tooling fixture 52, a fixture conveying table 53, and a robot gripping component 54 arranged sequentially on the slide table 51.

[0033] The specific working principle is as follows: The tooling fixture 52 clamps cars of different models and transports them to the fixture conveyor 53 via the slide table 51. The fixture conveyor 53 then transports the cars to the station of the robot gripping component 54. After the robot grips the car, the detection component 14 of the multi-grip gripping device detects the car model and sends a signal to the rotary table 11. The rotary table 11 identifies the corresponding fixture 4 and rotates it to the picking position so that the corresponding car can be clamped and input into the next station for welding.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
