Description

Technical Field

[0001] The utility model belongs to the field of manipulators, and in particular relates to a three-dimensional swing arm truss type processing device for an eccentric shaft. Background Art

[0002] A workpiece whose outer circle is parallel to the axis of the outer circle but does not overlap is called an eccentric shaft. The eccentric shaft is generally fixed to the rotating shaft of the motor through an eccentric hole, and performs a cam motion when the motor starts. Therefore, it is widely used in automobiles, engines, pumps, etc. At present, the processing of eccentric shafts is all done by CNC machine tools, but this processing requires manual loading and cannot be done by traditional robotic arms. This is because the feed port of existing CNC machine tools is on the side. If the robotic arm is set in the direction of the machine tool, the raw material cannot be fed into the machine tool in the vertical direction. If the track of the robotic arm passes through the machine tool, it will affect the processing process. However, manual loading will cause problems such as insufficient production efficiency and worker personal safety. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0025] Example

[0026] like Figures 1-10 As shown, this embodiment includes a loading base 1 for placing blanks to be processed and finished products, a first machine tool 2 and a second machine tool 3 located on both sides of the loading base 1 for processing the blanks into finished products, and a transfer track 4 for transferring the blanks and finished products between the loading base 1 and the first machine tool 2 and the second machine tool 3.

[0027] like Figures 1-6 As shown, a transfer track 4 is fixed above the loading base 1 via a bracket. The entire structure of the transfer track 4 passes directly above the first machine tool 2, the loading base 1, and the second machine tool 3. A swing arm device 5 is provided on the transfer track 4, which can move along the transfer track 4 to above the first machine tool 2, the loading base 1, or the second machine tool 3. The swing arm device 5 includes a slide 6 equipped with a first rotary motor 7 and a robotic arm device connected to the first rotary motor 7. The robotic arm device includes a protective member 8 connected to the first rotary motor 7, a vertical track 9 fixed within the protective member 8, and a robotic arm 10 connected to the vertical track 9 and relatively perpendicular to the transfer track 4. Driven by the first rotary motor 7, the protective member 8 can swing a certain angle around the connection point, thereby driving the vertical track 9 within the protective member 8 and the robotic arm 10 to swing together, thereby changing the positional relationship between the robotic arm 10 and the first machine tool 2, the loading base 1, or the second machine tool 3. A manipulator device that can be used to grab the workpiece is provided at the lower part of the manipulator arm 10. The manipulator arm 10 can move in the vertical direction along the vertical track 9 under the drive of the motor 30, so as to control the distance between the manipulator device and the object to be grabbed.

[0028] like Figures 1-6As shown, the robot device includes a rotary motor 11 fixed to the bottom of the robot arm 10, a rotating member 12 connected to one side of the rotary motor 11 and rotatable under the drive of the rotary motor 11, and a set of mechanical claws 13 fixed to the rotating member 12 at a 90-degree angle. The front ends of the mechanical claws 13 are provided with clamps 14 that can be opened and closed under the drive of the motor. The robot device grasps the workpiece through the clamps 14. The two mechanical claws 13 can grasp two workpieces at the same time. Specifically, after one mechanical claw 13 grasps, it is driven by the rotary motor 11 to rotate, so that the mechanical claw 13 that has not grasped the workpiece can be adjusted to a vertical grasping position during rotation for a second grasp.

[0029] like Figure 1-Figure 3 As shown, the loading base 1 is provided with a blank tray 15 for placing blanks and a finished product tray 16 for placing finished products. The robotic arm device moves along the transfer track 4 to the top of the loading base 1. The robotic arm device grabs the blank in the blank tray 15 through the robotic arm device. The robotic arm device then moves along the transfer track 4 to the top of the first machine tool 2 and the second machine tool 3. The blank is sequentially fed into the first machine tool 2 and the second machine tool 3 for eccentric shaft processing (turning). After processing is completed, the robotic arm device returns to the top of the loading base 1 and places the finished product into the finished product tray 16.

[0030] like Figure 1-Figure 2 、 Figure 9-10 As shown, the first machine tool 2 and the second machine tool 3 have roughly the same structure, and the only difference is the tool used for processing the eccentric shaft. The tool enters from the other side of the first machine tool 2 and the second machine tool 3, and both are prior art. The drawings of this embodiment are not drawn. A first processing cavity 17 is provided in the first machine tool 2, and a first limiting column 18 is provided at one end of the first processing cavity 17. A first slide rail 19 is provided in the first processing cavity 17, and a first processing device 20 is provided on the first slide rail 19 and can move along the first slide rail 19 toward the first limiting column 18. The first processing device 20 is provided with a rotatable limiting head 21 facing one end of the limiting column. The first limiting column 18 cooperates with the limiting head 21 to limit the raw material to be processed between the two. A second machining chamber 22 is provided within the second machine tool 3. A second limiting post 23 is provided at one end of the second machining chamber 22. A second slide rail 24 is provided within the second machining chamber 22. A second machining device 25 is mounted on the second slide rail 24 and is movable along the second slide rail 24 toward the second limiting post 23. A rotatable limiting head 21 is provided at one end of the second machining device 25 facing the second limiting post 23. The second limiting post 23 and limiting head 21 cooperate to limit the raw material to be machined between the two. In this embodiment, the limiting head 21 can be adjusted laterally on the first machining device 20 and the second machining device 25 to accommodate eccentric shaft components of different sizes.

[0031] The specific working process of the above-mentioned processing device is as follows: the robot arm device moves along the transfer track 4 to the top of the material placing base 1, the robot arm 10 moves down along the vertical track 9 until the robot claw 13 can grab the rough material placed in the rough material tray 15, repeat this process so that both robot claws 13 grab the rough material, and then the robot arm 10 moves up and resets, and the protective workpiece 8 is driven by the first rotating motor 7 and swings upward to a preset position with the connection as the axis. This position can ensure that the robot arm device will not touch the first machine tool 2 and the second machine tool 3 during the movement; then the robot arm device moves along the transfer track 4 to the top of the first machine tool 2, and the protective workpiece 8 is driven by the first rotating motor 7 and swings downward with the connection as the axis until the rough material in the robot claw 13 is between the first limit column 18 and the limit head 21, and then the first loading The working device 20 moves along the first slide rail 19 toward the first limit column 18 until the two clamp the rough material, and the protective workpiece 8 is driven by the first rotating motor 7 to swing upward to a preset position with the connection as the axis; when the first rough material is processed at one end, the mechanical claw 13 takes out the semi-finished product, drives the rotating motor 11 to rotate and puts in the second rough material, and repeats the process until two semi-finished products are obtained, and then the protective workpiece 8 is driven by the first rotating motor 7 to swing upward to a preset position with the connection as the axis, and the robotic arm device moves along the transfer track 4 to directly above the second machine tool 3, repeats the action in the first machine tool 2, and obtains two finished products, and finally the robotic arm device moves along the transfer track 4 to directly above the material placement base 1, and moves the robotic arm 10 down along the vertical track 9 until the robotic claw 13 puts the finished product into the finished product tray 16.

[0032] like Figure 1-Figure 2 、 Figure 7-Figure 8 As shown, a flipping device is fixed to one side of the bracket close to the material placing base 1. The flipping device includes a flipping base 26, a rotating cylinder 27 fixed on the flipping base 26, a flipping column 28 vertically fixed on the rotating cylinder 27 and with the top concave inward, and a guide 29 fixed on both sides of the flipping column 28 and with the upper part bent outward. The provided guide 29 cooperates with the flipping column 28 to enable the components to enter the flipping device better. The provided flipping device is used to flip the blank or the finished part to meet the needs during the processing or the storage needs after the processing is completed. In this embodiment, because the working directions of the first machine tool 2 and the second machine tool 3 are arranged in the same direction, in the process of the raw material completing the processing of the first machine tool 2 and entering the second machine tool 3 for processing, a robotic arm device is required to send the raw material into the flipping device for one turn.

Those skilled in the art of the present invention may make various modifications, additions, or substitute similar methods to the specific embodiments described, as long as they do not deviate from the contents of this specification or exceed the scope defined by the claims, and shall fall within the scope of protection of the present invention.
