Description

Technical Field

[0001] The present invention relates to the technical field of picking devices, and in particular to a claw pole part picking device driven by a linear motor. Background Art

[0002] Claw pole parts are parts with a complex shape and a high production demand. At present, the main manufacturing method of claw pole parts is forging. Typical forging equipment such as presses can quickly form the shape of relatively complex parts in cooperation with molds, and at the same time, it also has a significant effect on improving the microstructure of metal parts. It is the main means for producing parts with complex shapes and high strength performance requirements. In order to further improve the production efficiency of the press, feeding equipment for upper and lower materials is required, and this electromechanical coupling automation device naturally becomes the focus and difficulty in the research and development of forging equipment.

[0003] At present, the feeding of claw pole parts applied to presses mainly adopts two methods: manual feeding and robot feeding. During manual feeding, workers need to take out the workpieces on the mold and place them in the next station when the press slider is lifted. The disadvantages of this method are obvious. The working efficiency of workers is slow, the labor intensity is high, the positioning of the claw pole in the mold mainly depends on the visual observation and judgment of workers, and there are many unsafe factors in the working environment of a heavy machinery such as a multi-station press. Another method is to use a robot. The development of robot technology is already very mature. Currently, the robots applied to presses mainly include swinging crossbar manipulators, parallel four-bar manipulators, six-degree-of-freedom robots, etc. No matter which robot is used, a manipulator claw capable of grasping claw pole parts is required.

[0004] Due to the existence of pole claws, when placing claw pole parts into the mold, not only position positioning but also circumferential positioning is required. Currently, the main types of hand claws are magnetic adsorption and mechanical types. However, the current conventional hand claws can only achieve position positioning and cannot achieve circumferential positioning of parts. Therefore, an additional rotating positioning device for claw pole parts is required, which undoubtedly increases the complexity of the part transfer system and extends the feeding path. Moreover, too many processes may affect the production rhythm and reduce the production efficiency. In view of the problems existing in the manipulator claws for feeding claw pole parts, a more compact and efficient clamping hand claw for claw pole parts is needed, which can not only clamp parts but also achieve circumferential positioning of claw pole parts.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The present invention will now be further described in detail with reference to the drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0021] As Figures 1-3 shown, a claw pole part picking device driven by a linear motor includes a connecting flange assembly, a connecting plate assembly, a linear guide rail assembly, a support frame assembly and a roller group assembly. One end of the connecting flange assembly is connected to the linear guide rail assembly through the connecting plate assembly. The support frame assembly is close to the roller group assembly.

[0022] The connecting flange assembly includes a connecting flange 1 and a connecting rod 2. The connecting plate assembly includes a support plate 3, a rotating shaft 4, and a rotating mounting plate 5. The linear guide rail assembly includes a linear motor stator 6, a linear motor mover 7, a linear motion frame 8, a linear slider 9, and a linear guide rail 10. The support frame assembly includes an elastic column 16, a first elastic column support bracket 15-1, and a second elastic column support bracket 15-2. The roller group assembly includes an auxiliary support plate 12, a roller mounting arc seat 13, and a roller group 14. The connecting rod 2 fixedly connects the connecting flange 1 and the support plate 3 together. The rotating shaft 4 and the rotating mounting plate 5 are hinged to the support plate 3. The linear motor stator 6 is mounted on the rotating mounting plate 5. The linear motor mover 7 that cooperates with the linear motor stator 6 is mounted on the linear motion frame 8. The linear slider 9 is mounted on the linear motion frame 8. The linear guide rail 10 that cooperates with the linear slider 9 is mounted on the rotating mounting plate 5. The auxiliary support plate 12 is fixedly connected to the support plate 3. The roller mounting arc seat 13 is fixedly mounted on the auxiliary support plate 12. The roller group 14 is mounted on the roller mounting arc seat 13. The first elastic column support bracket 15-1 and the second elastic column support bracket 15-2 are fixedly mounted on the support plate 3. The linear guide rail assembly further includes a friction plate 11, and the friction plate 11 is mounted on the linear motion frame 8. The linear guide rail assembly further includes an elastic column buckle 17. The elastic column 16 passes through the first elastic column support bracket 15-1, the second elastic column support bracket 15-2, and the elastic column buckle 17, and the elastic column buckle 17 is hinged to the linear motion frame 8.

[0023] As Figure 2 shown, after the claw pole part 18 leans on the roller group 14, as long as a tangential frictional force is applied to the claw pole part 18 through the friction plate 11, the claw pole part 18 can be pushed to rotate, thereby realizing the circumferential positioning of the claw pole part 18.

[0024] As Figure 3 shown, the first elastic column support bracket 15-1 and the second elastic column support bracket 15-2 are fixedly mounted on the support plate 3. The elastic column 16 passes through the first elastic column support bracket 15-1, the second elastic column support bracket 15-2, and the elastic column buckle 17, and the elastic column buckle 17 is hinged to the linear motion frame 8. In this way, when the linear motor works to push the friction plate 11 to move in the left direction in the figure, the claw pole part 18 is rotated. At the same time, since the linear motion frame 8 also moves to the left, the elastic column buckle 17 also moves to the left, and then the elastic column 16 is bent. The reaction force generated by the bending of the elastic column 16 also pushes the friction plate 11 to apply a radial force to press the claw pole part.

[0025] The working principle of the present invention is:

[0026] In the initial state, as Figure 1 shown, the linear motor stator 6 and the linear motor mover 7 drive the linear motion frame 8 to move. Due to the restriction of the elastic column 16, the elastic column buckle 17 on the linear motion frame 8 makes the elastic column buckle 17, the first elastic column support frame 15-1, and the second elastic column support frame 15-2 in a collinear position. The above structure enables the friction plate 11 to rotate around the rotating shaft 4 when the linear motor works, thereby changing the distance between the friction plate 11 and the roller group 14. In the initial state, the distance between the friction plate 11 and the roller group 14 is slightly larger than the diameter of the claw pole part 18. When the robot controls the movement of the present invention onto the claw pole part 18, as Figure 2 shown, the linear motor controls the friction plate 11 to contact the claw pole part 18. As Figure 3 shown, the linear motor continues to work. Due to the limitation of the claw pole part 18 between the friction plate 11 and the roller group 14, the distance between the friction plate 11 and the roller group 14 no longer decreases. The continuous movement of the linear motor pushes the spring buckle 17 towards the connecting flange 1 and compresses the elastic column 16 to bend. The reaction force of this bending enables the friction plate 11 to tightly press the claw pole part 18. At the same time, the linear movement of the friction plate 11 can also achieve the circumferential rotation and positioning of the claw pole.

[0027] Afterwards, the present invention places the claw pole part 18 in the mold. Since the claw poles of the claw pole part 18 are clamped into the mold, when the linear motor moves in the reverse direction to control the friction plate 11 to release the claw pole part 11, the claw pole part 18 will not rotate. After the friction plate 11 completely releases the claw pole part 18, the part placement is completed. The present invention can return to its original position and wait for the next working cycle under the operation of the industrial robot.

[0028] Taking the ideal embodiments of the present invention described above as inspiration, through the above description, relevant staff can completely make various changes and modifications within the scope not deviating from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
