Description

Technical Field

[0001] The present invention relates to the technical field of insulators, and particularly to a rotary positioning device for an insulator suspension bracket. Background Art

[0002] An insulator is a device installed between conductors at different potentials or between a conductor and a grounding member, and can withstand voltage and mechanical stress. There are various types of insulators with different shapes. Although the structures and appearances of different types of insulators are quite different, they are all composed of two major parts: an insulating part and a connecting fitting. Insulators are usually made of glass or ceramics.

[0003] In an insulator production line, generally, a suspension bracket is used to transfer the produced insulators. The actual transmission structure of the suspension bracket is chain drive, that is, the suspension bracket is transferred by a conveyor chain. In the past, the produced insulators were often placed in the carrier tray on the suspension bracket or taken out of the carrier tray manually, with low efficiency. With the progress of technology, a manipulator with high automation has good application prospects in the field of insulator production. However, due to the lack of a limiting structure at the bottom of the suspension bracket itself, it will swing during transportation, which is not conducive to the manipulator accurately finding the placement position. Moreover, multiple insulators need to be placed around the carrier tray, and the manipulator needs to continuously adjust its orientation to match the insulator placement position, wasting time and reducing the transfer efficiency of the insulators.

[0004] Therefore, there is an urgent need for a rotary positioning device for an insulator suspension bracket to improve the transfer efficiency of insulators. Summary of the Invention

[0005] The purpose of the present invention is to provide a rotary positioning device for an insulator suspension bracket to solve the problems existing in the above-mentioned prior art. The upper part of the suspension bracket is positioned by a clamping locator, and the lower part of the suspension bracket is assisted in positioning by the cooperation of the limiting channel and the push of the rotary motor, improving the positioning effect. At the same time, the rotary motor can drive the suspension bracket to rotate during the transportation by the robotic arm, aligning the groove for carrying the insulators with the robotic arm, which can effectively improve the transfer efficiency of the insulators.

[0006] To achieve the above object, the present invention provides the following solutions: The present invention provides an insulator suspension frame rotation positioning device, including a suspension frame, a clamping locator with loosening and clamping functions, a limiting channel, a rotating motor, and a translation mechanism. A plurality of bearing disks are coaxially arranged on the suspension frame, and a plurality of grooves for placing insulators are circumferentially arranged on the bearing disks. The top of the suspension frame is rotatably arranged in the clamping hole of the clamping locator. The limiting channel is arranged corresponding to the bottom of the suspension frame. The orientation of the limiting channel is parallel to the conveying direction of the suspension frame. The width of the limiting channel matches the diameter of the bottom of the suspension frame. A first gear is coaxially arranged on the suspension frame, and a second gear meshing with the first gear is arranged at the output end of the rotating motor. The rotating motor is arranged on the translation mechanism, and the movement direction of the translation mechanism intersects with the channel orientation of the limiting channel.

[0007] Preferably, both the limiting channel and the translation mechanism are arranged on a base. A vertical column is arranged on the base, and the top of the vertical column is connected to the clamping locator.

[0008] Preferably, a detector for detecting the movement of the suspension frame in place is arranged at the top of the vertical column. The detector, the clamping locator, and the control system are electrically connected.

[0009] Preferably, both ends of the limiting channel in the movement direction of the suspension frame are of a flared structure.

[0010] Preferably, the movement direction of the translation mechanism is perpendicular to the channel orientation of the limiting channel.

[0011] Preferably, a plurality of detection blocks are evenly arranged on the outer edge of at least one of the bearing disks. A travel switch for cooperating with the detection blocks to determine the rotation angle is arranged on the outer peripheral side of the bearing disk. The travel switch and the rotating motor are both electrically connected to the control system.

[0012] Preferably, a plurality of card slots are evenly arranged on the outer edge of at least one of the bearing disks. The card slots correspond to the detection blocks. A pushing member is arranged on the outer peripheral side of the bearing disk. The pushing member moves towards or away from the bearing disk. A clamping block matching the card slot is arranged at the end of the pushing member close to the bearing disk. The driving device of the pushing member and the travel switch are both electrically connected to the control system.

[0013] Preferably, a spherical or cylindrical rolling body is rotatably arranged on the clamping surface of the clamping hole of the clamping locator. The rolling body contacts the suspension frame.

[0014] Preferably, the top of the suspension bracket is connected to the conveying chain through a connecting piece. A bearing is embedded at the end of the connecting piece close to the suspension bracket, and the suspension bracket is rotatably connected to the connecting piece through the bearing.

[0015] Preferably, the suspension bracket includes a cylindrical rod body and a threaded rod. The top of the rod body is threadedly connected to the threaded rod, and the end of the threaded rod away from the rod body is rotatably connected to the connecting piece through the bearing.

[0016] The present invention mainly achieves the following technical effects compared with the prior art:

[0017] While using the clamping locator to clamp the top of the suspension bracket, it does not interfere with the rotation of the suspension bracket itself, and only performs circumferential positioning on it. The limiting channel corresponding to the bottom of the suspension bracket can assist in limiting the bottom of the suspension bracket in both side directions, and cooperate with the clamping locator to achieve a good positioning effect, which helps the robotic arm to accurately grasp the insulator in the tank. On the basis of completing the positioning, the rotating motor can drive the suspension bracket to rotate. When the robotic arm returns, the suspension bracket can be driven to rotate, rotating the tank arranged in a circle and carrying the insulator to the position corresponding to the robotic arm, saving the time for the robotic arm to clamp at an angle and effectively improving the transfer efficiency of the insulator.

[0018] The following technical effects are achieved by other solutions of the present invention compared with the prior art:

[0019] After the detector detects that the suspension bracket is in place, the system controls the clamping locator to clamp the suspension bracket, improving the automation degree of the system.

[0020] The setting that the movement direction of the translation mechanism is perpendicular to the channel orientation of the limiting channel can, after the first gear and the second gear are engaged, prevent the suspension bracket from having a tendency to slide along the orientation of the limiting channel, and can limit the movement of the suspension bracket along the orientation of the limiting channel by the engagement between the teeth, improving the positioning effect.

[0021] The setting of the travel switch and the detection block can enable the system to accurately sense the rotation in place and thus perform braking, improving the rotation accuracy of the suspension bracket. Moreover, the cooperation between the clamping block and the clamping groove can assist in locking the current rotation angle, further improving the rotation accuracy of the suspension bracket.

Specific embodiments

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] The object of the present invention is to provide a rotary positioning device for an insulator suspension bracket to solve the problems existing in the prior art. The upper part of the suspension bracket is positioned by a clamping locator, and the lower part of the suspension bracket is assisted in positioning by the cooperation of the limiting channel and the pushing out of the rotary motor, so as to improve the positioning effect. At the same time, the rotary motor can drive the suspension bracket to rotate during the transportation of the manipulator, and the groove body carrying the insulator is aligned with the manipulator, which can effectively improve the transfer efficiency of the insulator.

[0035] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Please refer to as Figures 1 to 9 As shown in the figure, a rotary positioning device for an insulator suspension bracket is provided, which includes a suspension bracket 1, a clamping locator 2 with the functions of loosening and clamping, a limiting channel 3, a rotary motor 4 and a translation mechanism 5. A plurality of bearing plates 6 are coaxially arranged on the suspension bracket 1, and a plurality of grooves 7 for placing insulators are circumferentially arranged on the bearing plates 6. When the clamping locator 2 is in the unclamped state, its clamping arms should not be located on the transportation path of the suspension bracket 1. Preferably, the clamping locator 2 is arranged on one side of the transportation direction of the suspension bracket 1, and the clamping locator 2 is a circular arc opening and closing type gripper whose two clamping arms can rotate arc-shaped to a parallel state. Of course, a circular arc parallel opening and closing type or a linear parallel opening and closing type gripper can also be selected. However, when these two types of grippers are selected, a telescopic rod needs to be set to drive the clamping arms of the gripper to move away from the transportation path of the suspension bracket 1 in the unclamped state to avoid position interference. The clamping hole of the clamping locator 2 is a round hole matching the top of the suspension bracket 1, and the top of the suspension bracket 1 is rotatably arranged in the clamping hole of the clamping locator 2. The inner wall of the clamping hole contacts but does not squeeze the suspension bracket 1, does not interfere with the rotation of the suspension bracket 1 itself, and only completes the circumferential positioning of it. The limiting channel 3 is arranged corresponding to the bottom of the suspension bracket 1, the orientation of the limiting channel 3 is parallel to the transportation direction of the suspension bracket 1, and the width of the limiting channel 3 matches the diameter of the bottom of the suspension bracket 1. A first gear 8 is coaxially arranged on the suspension bracket 1, a second gear 9 meshing with the first gear 8 is arranged at the output end of the rotary motor 4, the rotary motor 4 is arranged on the translation mechanism 5, and the movement direction of the translation mechanism 5 intersects with the channel orientation of the limiting channel 3. The working principle of this device is as follows: while the clamping locator 2 clamps the top of the suspension bracket 1, the limiting channel 3 corresponding to the bottom of the suspension bracket 1 can assist in limiting the bottom of the suspension bracket 1 in both side directions, and cooperate with the clamping locator 2 to achieve a good positioning effect, which is helpful for the manipulator to accurately grasp the insulators in the groove 7. On the basis of the positioning being completed, the rotary motor 4 can drive the suspension bracket 1 to rotate. When the manipulator returns, the suspension bracket 1 can be driven to rotate, and the groove bodies 7 carrying the insulators arranged in a circle are rotated to the position corresponding to the manipulator, saving the time for the manipulator to clamp at an angle and effectively improving the transfer efficiency of the insulators.

[0037] An additional clamping locator 2 can also be provided at the bottom of the corresponding suspension bracket 1 to further improve its positioning effect.

[0038] Preferably, the moving direction of the translation mechanism 5 is perpendicular to the channel orientation of the limiting channel 3. After the first gear 8 and the second gear 9 are engaged, it can prevent the suspension bracket 1 from having a tendency to slide along the orientation of the limiting channel 3, and can also limit the upward movement of the suspension bracket 1 along the limiting channel 3 by using the tooth engagement, thereby improving the positioning effect.

[0039] The limiting channel 3 is formed by the blocking objects on both sides. The blocking objects can be in a block structure or a rod structure. In this embodiment, the selected blocking object is the blocking rod 10, that is, two parallel blocking rods 10 are provided on both sides of the conveying direction of the suspension bracket 1, and the limiting channel 3 is formed between the blocking rods 10.

[0040] In order to better introduce the suspension bracket 1 into the limiting channel 3, both ends of the limiting channel 3 in the moving direction of the suspension bracket 1 are in a flared structure.

[0041] The limiting channel 3 and the translation mechanism 5 are both provided on the base 11. A vertical column 12 is provided on the base 11, and the top of the column 12 is connected to the clamping locator 2.

[0042] The translation mechanism 5 can be selected as telescopic rod translation or screw drive translation. When the telescopic rod translation is selected, the fixed end of the rotary motor 4 is connected to the telescopic end of the telescopic rod, and the telescopic rod drives the rotary motor 4 to move. The telescopic rod can be selected as a pneumatic, hydraulic or electric telescopic rod. At the same time, a matching structure of a slide rail and a slide groove can be provided between the bottom of the rotary motor 4 and the base 11 to guide the movement of the rotary motor 4 and improve the movement stability; when the screw drive translation is selected, a driving motor needs to be provided to drive the screw to rotate, and the rotary motor 4 is threadedly connected to the screw through a nut seat. Similarly, a matching structure of a slide rail and a slide groove can be provided between the bottom of the rotary motor 4 and the base 11 to provide guidance and improve the movement stability.

[0043] A detector 13 for detecting the movement of the suspension bracket 1 in place is provided at the top of the column 12. The detector 13 can be selected as a camera and an analysis system, and it can judge whether it is in place through image analysis, or a travel switch can be selected for detection. The probe of the travel switch can not affect the normal conveying of the suspension bracket 1 when it continues to be conveyed, or a laser rangefinder can be selected. The detector 13 is electrically connected to the clamping locator 2 and the control system, and transmits the in-place signal to the control system. The control system controls the suspension bracket 1 to stop conveying. After using the detector 13 to detect that the suspension bracket 1 is in place, the system controls the clamping locator 2 to clamp the suspension bracket 1, thereby improving the automation degree of the system.

[0044] A number of detection blocks 14 are evenly arranged on the outer edge of at least one carrier plate 6. A travel switch 15 for cooperating with the detection blocks 14 to determine the rotation angle is arranged on the outer peripheral side of the carrier plate 6. Specifically, the travel switch 15 is arranged on the column 12. Both the travel switch 15 and the rotary motor 4 are electrically connected to the control system. The arrangement of the travel switch 15 and the detection blocks 14 enables the system to accurately sense the rotation in place, thereby performing braking and improving the rotation accuracy of the suspension rack 1. For example, four detection blocks 14 are evenly arranged on the outer edge of the carrier plate 6. When the detection block 14 hits the travel switch 15, it indicates that it has rotated 90 degrees, and then the rotation information is transmitted to the control system. The control system controls the rotary motor 4 to stop. After the manipulator finishes grasping or placing, the control system controls the rotary motor 4 to start and stop when the lower detection block 14 hits the travel switch 15, and so on.

[0045] A number of card slots 16 are evenly arranged on the outer edge of at least one carrier plate 6. The card slots 16 correspond to the detection blocks 14. A pushing member 17 is arranged on the outer peripheral side of the carrier plate 6. The pushing member 17 moves towards or away from the carrier plate 6. Specifically, the movement of the pushing member 17 can be controlled by a telescopic rod or a screw drive. A clamping block 18 matching the card slot 16 is arranged at the end of the pushing member 17 close to the carrier plate 6. The driving device of the pushing member 17 and the travel switch 15 are both electrically connected to the control system. The cooperation between the clamping block 18 and the card slot 16 can assist in locking the current rotation angle, further improving the rotation accuracy of the suspension rack 1.

[0046] The detection block 14 on one carrier plate 6, its adapted travel switch 15, the card slot 16 on one carrier plate 6, and its adapted clamping block 18 can be used as a detection and locking group. Each suspension rack 1 can include multiple groups of detection and locking groups. The positions of the detection blocks 14 in different groups can correspond or be offset.

[0047] The column 12 is hollow, and the circuit lines required for each component are arranged inside.

[0048] In the present invention, five carrier plates 6 are arranged on the suspension rack 1. Detection blocks 14 are arranged on the second and fourth carrier plates 6 from top to bottom, and card slots 16 are arranged on the third and fifth carrier plates 6.

[0049] In order to reduce the frictional force between the clamping locator 2 and the suspension bracket 1 and reduce the energy consumption of the rotating motor 4 for driving the rotation of the suspension bracket 1, a spherical or cylindrical rolling body 19 is rotatably arranged on the clamping surface of the clamping hole of the clamping locator 2. The rolling body 19 can be directly embedded in the clamping surface, and lubricating oil is added to the embedding hole. When a cylindrical rolling body 19 is used, if a wheel-like structure is adopted, a horizontal groove can be opened in the middle of the clamping surface of the clamping arm, and holes for installing a rotating shaft can be opened at positions corresponding to the upper and lower parts of the horizontal groove. The rotating shaft is installed in the holes, and the wheel-like structure is rotatably arranged on the rotating shaft and located in the horizontal groove. The rolling body 19 contacts the suspension bracket 1, changing the original surface contact to point or line contact.

[0050] The specific structure of the rotation of the suspension bracket 1 is as follows: The top of the suspension bracket 1 is connected to the conveying chain through a connector 20. The connector 20 includes a cylindrical part and a lug, and the lug is used for connecting with the conveying chain. A bearing is embedded at the end of the cylindrical part of the connector 20 close to the suspension bracket 1, and the suspension bracket 1 is rotatably connected to the connector 20 through the bearing.

[0051] The suspension bracket 1 includes a cylindrical rod body and a threaded rod. The top of the rod body is threadedly connected to the threaded rod. The end of the threaded rod away from the rod body is rotatably connected to the connector 20 through a bearing. The installation and disassembly of the rod body can be conveniently realized through threaded connection.

[0052] During the actual use process, the conveying chain transports the suspension bracket 1 above the base 11. After the detector 13 detects that the suspension bracket 1 is in place, the control system controls the clamping locator 2 to clamp the top of the suspension bracket 1. The bottom of the suspension bracket 1 enters the limiting channel 3. At this time, the translation mechanism 5 drives the rotating motor 4 to move until the first gear 8 meshes with the second gear 9; the rotating motor 4 is controlled to start. When the detection block 14 on the bearing plate 6 contacts the travel switch 15 on the column 12, the rotating motor 4 stops. The manipulator grabs or places the insulator. After the manipulator completes the action and returns, at this time, the rotating motor 4 starts again and rotates until the next detection block 14 contacts the travel switch 15, and so on in sequence until the bearing plate 6 is full or emptied; the translation mechanism 5 drives the rotating motor 4 to move, cancels the meshing of the first gear 8 and the second gear 9, the clamping locator 2 releases the clamping of the suspension bracket 1, and the conveying chain continues to transport the next suspension bracket 1 above the base 11.

[0053] Adaptations made according to actual needs are all within the protection scope of the present invention.
