Abstract
Description
Technical Field
[0001] The utility model relates to the field of mechanical manufacturing, in particular to a shaft rod commutator used for a shaft rod processing unit and the shaft rod processing unit. Background Art
[0002] In existing application scenarios, shaft rod processing can only process one side of the shaft rod, but the shaft rod is actually processed on both sides, so manual reversing is required to achieve double-sided processing of the shaft rod. This processing method has disadvantages: First, since one side of the shaft rod has just been machined, some cutting fluid still remains on the surface of the shaft rod. At this time, when the shaft rod is manually moved for reversing, the shaft rod is very easy to slip out of the hand, posing a safety risk; second, the shaft rod processing is automated, and manual reversing of the shaft rod is impossible in time, reducing production efficiency; third, the manual reversing station is placed inside the automated processing unit, which is automated, and human participation in reversing the shaft rod will pose a safety risk to humans.
[0003] The current solutions are as follows: First, when manually reversing, the surface of the shaft rod is wiped clean before reversing, which reduces production efficiency; second, when the automatic operation reaches the reversing station, a timed waiting is performed. If the waiting time is too long, an alarm is issued to remind the operator to perform the reversal in time; third, when manually reversing, the automatic operation is manually stopped, and after the reversal is completed, the automatic operation is restarted. This method reduces production efficiency. Utility Model Content

[0006] In this way, the commutator of the utility model can realize automatic reversal of the shaft rod, save time, and improve production efficiency and safety.
[0007] In an exemplary embodiment, the shaft rod commutator further comprises a proximity sensor located on the support, wherein the proximity sensor is configured to detect whether the shaft rod to be commutated is transported to the support structure, and when the proximity sensor detects that the shaft rod to be commutated is transported to the support structure, the clamping mechanism is switched from the open configuration to the clamping configuration.
[0008] In this way, the commutator of the utility model can use the proximity sensor to detect whether the shaft rod to be commutated is transported to the support structure, so that when the shaft rod is detected, the clamping mechanism can be immediately converted from the open configuration to the clamping configuration, and the shaft rod is clamped by the clamping mechanism, thereby improving the commutation efficiency and preventing the shaft rod from falling to the ground.

[0010] In this way, the commutator of the present invention can utilize two clamping mechanisms with a specific arrangement to firmly clamp and commutate the shaft rod.
[0011] In an exemplary embodiment, the central axis of the first arm is perpendicular to the central axis of the piston rod of the driving cylinder, and the central axis of the second arm is perpendicular to the central axis of the first arm and parallel to the central axis of the piston rod of the driving cylinder.

[0013] In an exemplary embodiment, a cross section of the first arm in a direction perpendicular to a central axis of the first arm is a rectangular shape, and a cross section of the second arm in a direction perpendicular to the central axis of the second arm is a rectangular shape.
[0014] In this way, the commutator of the utility model has a solid structure and a reasonable layout, and can achieve stable clamping and commutation of the shaft rod.
[0015] In an exemplary embodiment, the support has two support structures, each of which has a V-shaped groove at its upper end to receive the shaft rod to be reversed, and each of which has a lower end fixedly mounted to the upper surface of the support.

[0045] In order to make the purpose, technical scheme and advantages of the utility model clearer, the utility model is further described in detail with reference to the following embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. The nouns and pronouns about people in this patent application are not limited to specific genders.
[0046] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is intended to include the plural form as well.
[0047] First, please refer to Figure 1 , shows a shaft rod commutator for a shaft rod processing unit of an exemplary embodiment of the utility model. It is explained here that the shaft rod processing unit mentioned here is generally a shaft rod processing automation unit. The shaft rod is, for example, the rotor shaft of the rotor of a motor. In existing application scenarios, shaft rod processing can only process one side of the shaft rod, but the shaft rod is actually processed on both sides, so the shaft rod needs to be commutated. For example, during processing, the end of one side of the shaft rod is fixed by the chuck of the machine tool, and the other side is processed by a processing tool, such as milling by a milling cutter. Therefore, after processing one side, the shaft rod can be transported to the shaft rod commutator for the shaft rod processing unit of the utility model by a mechanical gripper such as a truss for commutation, and after the shaft rod is turned 180 degrees by the shaft rod commutator, a mechanical gripper such as a truss is used to transport the shaft rod from the shaft rod commutator to the processing station for processing the other side.
[0048] A shaft rod commutator for a shaft rod processing unit according to an exemplary embodiment of the utility model comprises: a support 10, on which a support structure 11 for supporting a shaft rod 50 to be commutated is provided; a clamping mechanism 20, which comprises a clamping component and a driving mechanism for driving the clamping component, and the clamping mechanism has an open configuration and a clamping configuration, in which ( Figure 1 ), the pressing member is in a position to expose the space above the support structure 11 so that the shaft rod 50 to be reversed can be transported to the support structure 11 by a mechanical gripper such as a truss, and in the pressing configuration ( Figure 2 As shown), the clamping component is located above the support structure 11, and the clamping component cooperates with the support structure 11 to clamp the shaft rod 50 to be reversed in place; and a rotating mechanism 30, the rotating mechanism is transmission-connected to the support 10, and the rotating mechanism is configured to enable the support 10 to rotate at an angle of 180 degrees to achieve the reversal of the shaft rod 50.
[0049] Reference Figure 1 The shaft-rod commutator further includes a proximity sensor 40 located on the support 10, and the proximity sensor 40 is configured to detect whether the shaft-rod 50 to be commutated is transported to the support structure 11. When the proximity sensor 40 detects that the shaft-rod is transported to the support structure 11, the clamping mechanism 20 is switched from the open configuration to the clamping configuration. The proximity sensor 40 can be arranged in the area between the two support structures 11.
[0050] Reference Figure 1 The shaft rod commutator includes two clamping mechanisms 20, wherein the driving mechanism of each clamping mechanism includes a driving cylinder 21; wherein the clamping component of each clamping mechanism includes a first arm 22 and a second arm 23 connected to each other, the first end of the first arm 22 is connected to the piston rod of the driving cylinder 21 and the second end of the first arm 22 is fixedly connected to the first end of the second arm 23, so as to transmit the rotational motion and telescopic motion from the driving cylinder 21 to the first arm 22 and the second arm 23, so that the first arm 22 and the second arm 23 can rotate 90 degrees and can move in the vertical direction. The shape of the second end of the second arm 23 is configured to be suitable for clamping a part of the circumference of the shaft rod 50 to be commutated. The first arm 22 and the second arm 23 can be connected by a connecting member, for example, by two screws.
[0051] Reference Figure 1 The central axis of the first arm 22 is perpendicular to the central axis of the piston rod of the driving cylinder 21, and the central axis of the second arm 23 is perpendicular to the central axis of the first arm 22 and parallel to the central axis of the piston rod of the driving cylinder 21. The cross section of the first arm 22 in a direction perpendicular to the central axis of the first arm 22 is a rectangular shape, and the cross section of the second arm 23 in a direction perpendicular to the central axis of the second arm 23 is a rectangular shape.
[0052] Reference Figure 1 The support 10 has two support structures 11, and the upper end of each support structure 11 is arranged with a V-shaped groove 111 suitable for receiving the shaft rod 50 to be reversed, and the lower end 112 of each support structure 11 is fixedly mounted to the upper surface of the support 10. Of course, it can be understood that the shape of the upper end of each support structure 11 can be appropriately changed, for example, a groove with a circular arc can be arranged.
[0053] Reference Figure 1 The shaft-rod commutator further includes a base 60, which is used to support the rotating mechanism 30; the rotating mechanism 30 includes a rotating cylinder located below the support 10, the cylinder body of the rotating cylinder is arranged above the base 60, and the piston rod of the rotating cylinder is connected to the support 10, so that the support 10 can rotate at an angle of 180 degrees. Both the base 60 and the support 10 are flat plate structures and extend in the horizontal direction.
[0054] Reference Figure 3 , indicating that the shaft rod commutator has completed the commutation of the shaft rod 50. At this time, Figure 1 The left and right ends of the shaft rod 50 have been compared to Figure 1 and Figure 2 The position of the shaft rod 50 is reversed. In this case, the clamping mechanism 20 can be converted to an open configuration so that the shaft rod can be transported from the shaft rod diverter to the processing station using a mechanical gripper such as a truss, thereby processing the unprocessed side of the shaft rod 50.
[0055] According to the shaft rod commutator and shaft rod processing unit of the utility model, the automatic control technology is used to realize the open configuration and the clamping configuration of the clamping mechanism. When there is no shaft rod placed on the commutator during the automated production process, the clamping mechanism is in the open configuration; when there is a shaft rod placed on the commutator during the automated production process, the cylinder 21 is driven to rotate 90 degrees and the second arm 23 is made to clamp the shaft rod 50, ensuring that the shaft rod is tightly locked and will not be thrown off the ground due to rotation.
[0056] In addition, during automatic operation, if a shaft rod is placed on the commutator, the proximity sensor 40 senses the shaft rod and the clamping mechanism switches to the clamping configuration; if the shaft rod is not placed on the commutator, the proximity sensor 40 does not sense the shaft rod and the clamping mechanism maintains the open configuration.
[0057] The rotating mechanism 30 uses a high-load rotating cylinder, because the shaft rod is heavy and has a high load, and a high-load rotating cylinder is required to drive the rotation, such as Figure 3 As shown, rotational stability is ensured. If the rotation is not in place, there will be a risk of collision of the automation unit.
[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
