Description

Technical Field

[0001] This utility model relates to the field of welding robot technology, specifically a clamping and flipping mechanism for a welding robot workstation. Background Technology

[0002] Welding robots are industrial robots that perform welding, including cutting and spraying. According to the International Organization for Standardization (ISO), industrial robots fall under the definition of standard welding robots. An industrial robot is a multi-purpose, reprogrammable, automatically controlled manipulator with three or more programmable axes, used in the field of industrial automation. Welding robots are highly automated devices that integrate industrial robot bodies and welding equipment, capable of replacing manual labor in performing complex processes such as arc welding, spot welding, and laser welding. These welding robots are mainly divided into spot welding robots, arc welding robots, and collaborative welding robots.

[0003] Existing technology, such as the patent with publication number CN221247562U, discloses a clamping and flipping mechanism for a welding robot workstation, including a worktable. A first motor is fixedly installed on one side of the worktable, and a rectangular groove is opened on the upper surface of the worktable. A bidirectional lead screw is installed inside the rectangular groove. A support plate is fixedly connected to the upper end of the base plate, and an adjustment chamber is provided at the upper end of the support plate. A first gear and a second gear are installed inside the adjustment chamber, and a connecting rod is provided on one side of the adjustment chamber. A clamp is fixedly connected to one side of the connecting rod, and a screw is threadedly connected to the upper end of the clamp.

[0004] While the aforementioned existing technologies have significant beneficial effects, they still have shortcomings:

[0005] The aforementioned flipping mechanism can fix two workpieces separately through two sets of clamping components, which facilitates the operation of the welding robot. However, the two sets of clamping components only use screws to drive the clamping plates for clamping. If the clamped object is heavy, and the screw itself has no locking structure, the clamped material is prone to instability during the flipping process, which can cause the material to shift, shake, or fall off the clamp, affecting the normal welding operation of the robot. Therefore, a clamping and flipping mechanism for a welding robot workstation is proposed. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a clamping and flipping mechanism for a welding robot workstation. Driven by a torque motor, it enables the flipping of materials held by the flipping frame. The drive clamping plate inside the flipping frame can work in conjunction with the extension and retraction of the telescopic rod to maintain stable clamping of the materials, thus facilitating the welding process.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a clamping and flipping mechanism for a welding robot workstation, comprising a main body, with clamping and flipping assemblies shaft-connected to both sides of the top surface of the main body. Each clamping and flipping assembly includes a flipping frame, with a clamping groove on the top surface of the flipping frame. A fixed clamping plate is fixed to one end of the flipping frame, and a rotating shaft is fixed to the center of the outer wall of the fixed clamping plate. A bearing bracket is fitted onto one end of the rotating shaft, and a drive shaft is fixedly connected to the other end of the flipping frame. A torque motor is shaft-connected to one end of the drive shaft, and a telescopic rod is fitted to the other end of the drive shaft. Sliding grooves are formed on both sides of the outer wall of the telescopic rod, and a drive clamping plate is fixed to one end of the telescopic rod. A rubber pad is attached to one side of the outer wall of the drive clamping plate, and a threaded shaft is threaded onto the other end of the telescopic rod. A servo motor is shaft-connected to one end of the threaded shaft, and a controller is fixed to one side of the servo motor.

[0008] Preferably, the drive clamp and the fixed clamp are sized to match, and the rubber pad is evenly attached to the outer wall of the drive clamp and the fixed clamp.

[0009] Preferably, the drive clamp plate is telescopically connected to one end of the drive shaft via a telescopic rod and a sliding groove, and the drive clamp plate is fixedly connected to one end of the telescopic rod.

[0010] Preferably, the telescopic rod forms a threaded transmission structure with one end of the drive shaft via a threaded shaft and a servo motor, and the servo motor is electrically connected to the controller.

[0011] Preferably, the tilting frame and the drive shaft form a rotating structure with the main body via a torque motor, and one end of the tilting frame is fixedly connected to the drive shaft.

[0012] Preferably, the main body includes a base frame, with mounting plates fixed at both ends of the base frame, knobs distributed at both ends of the mounting plates, screws fixed at the bottom ends of the knobs, and a base plate fixed at the bottom end of the screws. Clamping platforms are distributed at both ends of the top surface of the base frame, and a control panel is embedded in one outer wall of the clamping platform. The control panel is electrically connected to the torque motor via wires.

[0013] Preferably, the base plate is connected to the base frame via screws to form a threaded structure, and the clamping platform is fixedly connected to both ends of the top surface of the base frame.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model uses a torque motor to drive a drive shaft and a tilting frame for tilting adjustment, thereby turning the material held in the tilting frame. The drive clamping plate inside the tilting frame can work with the telescopic rod to maintain stable clamping of the material. The rubber pad increases surface friction, keeping the tilting process stable after clamping adjustment and preventing material shaking, thus facilitating the welding process.

[0016] 2. This clamping and flipping mechanism can be rotated by turning a knob, which will drive the screw connected to the bottom and the base plate to rotate synchronously, so that the base plate is at different levels around the bottom of the base frame. This makes it convenient for the whole device to be adjusted according to the welding environment. The clamping platforms at both ends of the top surface of the base frame are fixed structures, which can keep the mounting environment of the clamping and flipping assembly stable when the clamped material is flipped and adjusted, and provide a stable structural platform.

[0017] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained by means of the structures pointed out in the description, claims, and drawings. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This embodiment of a clamping and flipping mechanism for a welding robot workstation includes a main body 1. Clamping and flipping components 2 are axially connected to both sides of the top surface of the main body 1. The main body 1 includes a base frame 101. Mounting plates 102 are fixed to both ends of the base frame 101. Knobs 103 are distributed at both ends of the mounting plates 102. A screw 104 is fixed to the bottom end of the knob 103. A base plate 105 is fixed to the bottom end of the screw 104. Clamping platforms 106 are distributed at both ends of the top surface of the base frame 101. A control panel 107 is embedded in the outer wall of one side of the clamping platform 106. The control panel 107 is electrically connected to a torque motor 207 through wires.

[0025] like Figure 1-4 As shown, the clamping and flipping mechanism in this utility model is similar in structure to existing clamping and flipping mechanisms, such as the clamping and flipping mechanism for a welding robot workstation disclosed in CN221247562U. The main improvement of this utility model is that the drive shaft 206 and the flipping frame 201 connected by the torque motor 207 are used to drive the flipping adjustment, thereby realizing the flipping of the material clamped by the flipping frame 201. The drive clamping plate 210 inside the flipping frame 201 can cooperate with the transmission extension and retraction process of the telescopic rod 208 to maintain stable clamping of the material, keeping the flipping process after clamping adjustment stable and providing convenience for the welding process. In this utility model, both the servo motor 213 and the torque motor 207 are As is the existing technology, when using this clamping and flipping mechanism, the base frame 101 can be used as the bottom placement structure. With the help of the mounting plates 102 at both ends of the base frame 101, the installation process is kept stable. During the process, the user can rotate the knob 103. The rotation of the knob 103 drives the screw 104 connected to the bottom end and the base plate 105 to rotate synchronously, so that the base plate 105 is at different levels around the bottom of the base frame 101. This makes it convenient for the overall device to be adjusted according to the welding environment. The clamping platforms 106 at both ends of the top surface of the base frame 101 are fixed structures, which can keep the mounting environment of the clamping and flipping assembly 2 stable when the clamped material is flipped and adjusted, and provide a stable structural platform.

[0026] like Figure 2-4As shown, the clamping and flipping assembly 2 includes a flipping frame 201. A clamping groove 202 is formed on the top surface of the flipping frame 201. A fixing plate 203 is fixed to one end of the flipping frame 201. A rotating shaft 204 is fixed to the center of the outer wall of the fixing plate 203. A bearing bracket 205 is sleeved on one end of the rotating shaft 204. A drive shaft 206 is fixedly connected to the other end of the flipping frame 201. A torque motor 207 is shaft-connected to one end of the drive shaft 206. A telescopic rod 208 is sleeved on the other end of the drive shaft 206. Sliding grooves 209 are formed on both sides of the outer wall of the telescopic rod 208. A drive clamping plate 210 is fixed to one end of the telescopic rod 208. A rubber pad 211 is attached to one side of the outer wall of the drive clamping plate 210. The other end of the telescopic rod 208... The threaded sleeve is equipped with a threaded shaft 212, one end of which is connected to a servo motor 213. A controller 214 is fixed on one side of the servo motor 213. When using this mechanism to clamp materials, the user can first place the material to be processed on the plane of the flipping frame 201. Then, through the control panel 107, the controller 214 drives the servo motor 213 to rotate. The rotating threaded shaft 212 extends the threaded telescopic rod 208 along the slide groove 209, so that the drive clamping plate 210 at one end of the slide groove 209 cooperates with the fixed clamping plate 203 to clamp the material. Then, the torque motor 207 drives the whole thing to flip, completing the operation and adjustment process. The mechanism uses a torque motor 207 to drive the connected drive shaft 206 and the tilting frame 201 for tilting adjustment, thereby turning the material held in the tilting frame 201. The drive clamping plate 210 inside the tilting frame 201 works in conjunction with the transmission and extension process of the telescopic rod 208 to maintain stable clamping of the material. The rubber pad 211 increases surface friction, keeping the tilting process stable after clamping adjustment and preventing material shaking, thus facilitating the welding process.

[0027] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
