Description

Technical Field

[0001] The utility model relates to the technical field of tooth-shaped part processing, in particular to an angular structure used for tooth-shaped parts. Background Art

[0002] When loading the toothed workpiece, a conveyor belt is required to drive the toothed workpiece to the angular structure, so that it can perform angular positioning on the toothed workpiece, ensure the correct position and angle of the tooth, and ensure the accuracy and quality of the toothed workpiece processing.

[0003] Currently, when processing toothed workpieces, the workpieces are directly placed on a conveyor belt for transport and loading. In order to ensure the processing effect of the workpiece, it is necessary to ensure that the loading posture is consistent. Directly placing the workpiece on the conveyor belt cannot ensure the consistency of the placement posture of the toothed parts, thereby affecting the loading effect of the toothed workpiece.

[0004] Therefore, an angular structure for a toothed part is proposed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide an angular structure for toothed parts in order to solve the above problems, thereby improving the problem that the toothed workpiece is directly placed on a conveyor belt and the placement posture consistency of the toothed workpiece cannot be ensured.

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme, an angular structure for toothed parts, comprising: a conveying frame, a conveyor belt is arranged on the inner side of the conveying frame, and a positioning tool is arranged on the surface of the conveying belt; an anti-deviation mechanism, which is used to prevent the toothed workpiece from deviating during transportation on the surface of the conveyor belt, and the anti-deviation mechanism is arranged on the surface of the conveying frame; wherein the anti-deviation mechanism comprises a gear arranged at the bottom of the conveying frame, the surface of the gear is meshingly connected with two racks, the surface of the rack is fixedly connected with a movable frame, the bottom of the movable frame is fixedly connected with a positioning plate, and the bottom of the conveying frame is provided with a positioning assembly.

[0007] Preferably, the positioning assembly includes a servo motor fixedly connected to the bottom end of the gear, and the surface of the positioning plate is rollingly connected with ball bearings distributed in equal rows. The output shaft of the servo motor rotates through the gear, rack and movable frame to drive the two positioning plates and ball bearings to approach each other, so that the ball bearings contact the positioning tooling on the conveyor frame, thereby limiting the moving positioning tooling on the conveyor belt, ensuring that the positioning tooling will not deviate when moving to the angular structure, thereby improving the accuracy of angular positioning, and the ball bearings are used to reduce the resistance encountered by the positioning tooling during movement.

[0008] Preferably, a plurality of mounting brackets are fixedly connected to the top of the conveying frame, a cylinder is fixedly connected to one side of the mounting bracket, an angle block is arranged at one end of the cylinder, a screw is threadedly connected to the inner wall of the angle block, one end of the screw is threadedly connected to the inner wall of the cylinder, and one end of the plurality of cylinders moves in turn to drive their respective angle blocks to move toward the working pallet, and when one of the angle blocks extends out and hits the toothed workpiece in place, the angle is determined to be successful, and the subsequent cylinders will no longer move. The operation of angular positioning of the toothed workpiece is simple, and the screws facilitate the replacement of the angle blocks on the cylinder, avoiding the inconvenience of replacing severely worn angle blocks.

[0009] Preferably, a spring is fixedly connected to the surface of the movable frame, and the other end of the spring is fixedly connected to the surface of the conveying frame. The elastic force of the spring is used to increase the resistance of the movable frame approaching the positioning tooling, thereby reducing the impact force of the ball on the positioning tooling, so that the ball can gently contact the positioning tooling.

[0010] Preferably, a support rod is fixedly connected to the surface of the conveying frame, and the inner wall of the rack is slidably connected to the surface of the support rod. The support rod is used to support and limit the rack to avoid the rack having no support point, which causes the rack and gear to be unable to mesh and rotate.

[0011] Preferably, a stopper is fixedly connected to the surface of the support rod, and the diameter of the stopper is larger than the diameter of the support rod. The stopper limits the moving rack to prevent the rack from detaching from the gear surface during movement, thereby ensuring the stability of the meshing rotation of the rack and the gear.

[0012] Preferably, the bottom of the conveying frame is fixedly connected to a fixing frame, the bottom end of the gear is rotatably connected to the inner wall of the fixing frame, the surface of the servo motor is fixedly connected to the bottom of the fixing frame, and the fixing frame is used to support and limit the gear and the servo motor to ensure that the gear and the servo motor can work normally.

[0013] The beneficial effects of the utility model are:

[0014] 1. The output shaft of the servo motor rotates to drive the gear to rotate. The gear rotates to drive the two movable frames to approach each other through the rack. The spring is squeezed during the movement of the movable frame, so that the movable frame moves slowly and drives the positioning plate and the ball to move, so that the ball can gently contact the positioning fixture, ensuring that the positioning fixture will not deviate when moving to the angular structure, improving the accuracy of angular positioning, ensuring the consistency of the workpiece posture during loading, improving the loading effect of toothed workpieces, and being able to resist and limit positioning fixtures of different sizes, thereby increasing the diversity of anti-bias mechanisms;

[0015] 2. Multiple cylinders move one end at a time, driving their respective angular blocks to move toward the work tray. When one of the angular blocks extends out and contacts the toothed workpiece, the angular positioning is successful, and the subsequent cylinders will no longer move. After the angular positioning is successful, the robot calls the corresponding path program to grab the toothed workpiece. The angular positioning of the toothed workpiece is simple.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0023] When implementing: Figure 1-5As shown, an angular structure for toothed parts comprises: a conveying frame 1, a conveyor belt 3 is arranged on the inner side of the conveying frame 1, and a positioning tool 4 is arranged on the surface of the conveyor belt 3; an anti-deviation mechanism 2, which is used to prevent the toothed workpiece from deviating during transportation on the surface of the conveyor belt 3 and is arranged on the surface of the conveying frame 1; wherein the anti-deviation mechanism 2 comprises a gear 204 arranged at the bottom of the conveying frame 1, and the surface of the gear 204 is meshingly connected with two racks 203, and the surface of the rack 203 is fixedly connected with a movable frame 202, and the bottom of the movable frame 202 is fixedly connected with a positioning plate 201, and a positioning component 205 is arranged at the bottom of the conveying frame 1.

[0024] like Figure 2-5 As shown, the positioning assembly 205 includes a servo motor 2051 fixedly connected to the bottom end of the gear 204, the surface of the positioning plate 201 is rollingly connected with balls 2052 distributed in equal rows, the surface of the movable frame 202 is fixedly connected with a spring 2055, the other end of the spring 2055 is fixedly connected to the surface of the conveying frame 1, the top of the conveying frame 1 is fixedly connected with a plurality of mounting frames 2057, one side of the mounting frame 2057 is fixedly connected with a cylinder 2058, one end of the cylinder 2058 is provided with an angular block 2059, the inner wall of the angular block 2059 is threadedly connected with a screw 20510, one end of the screw 20510 is threadedly connected to the inner wall of the cylinder 2058, the bottom of the conveying frame 1 is fixedly connected with a fixing frame 2056, the bottom end of the gear 204 is rotatably connected to the inner wall of the fixing frame 2056, and the surface of the servo motor 2051 is fixedly connected to the bottom of the fixing frame 2056;

[0025] When it is necessary to load the toothed workpiece, the toothed workpiece is placed on the positioning fixture 4, and the positioning fixture 4 is placed on the conveyor belt 3, and the servo motor 2051 is started. The output shaft of the servo motor 2051 rotates to drive the gear 204 to rotate and drive the conveyor belt 3 to transmit. The conveyor belt 3 transmits and drives the positioning fixture 4 to move. The rotation of the gear 204 drives the two racks 203 to approach each other. The movement of the rack 203 drives the movable frame 202 to move. The spring 2055 is squeezed during the movement of the movable frame 202. The movement of the movable frame 202 drives the positioning plate 201 to move. The spring 2055 is used to increase the resistance of the positioning plate 201 to move, thereby reducing the impact force of the ball 2052 on the positioning fixture 4, so that the ball 2052 can gently contact the positioning fixture 4. The movement of the positioning plate 201 drives the positioning plate 201 to move, so that the two positioning plates 201 and the ball 2052 are close to each other and resist the positioning fixture 4. Limiting ensures that the positioning fixture 4 will not deviate when it moves to the angular structure, thereby improving the accuracy of angular positioning. It can resist and limit positioning fixtures 4 of different sizes, thereby improving the diversity of using the anti-deviation mechanism 2. The ball 2052 is used to reduce the resistance encountered by the positioning fixture 4 during movement. When the positioning fixture 4 moves to the appropriate position, one end of multiple cylinders 2058 moves in sequence to drive their respective angular blocks 2059 to move toward the work pallet. When one of the angular blocks 2059 extends out and resists the toothed workpiece in place, the angular positioning is determined to be successful, and the subsequent cylinders 2058 no longer move. After the angular positioning is successful, the robot calls the corresponding path program for grasping, thereby ensuring that the workpiece posture is consistent during loading, thereby improving the loading effect of the toothed workpiece, and the angular positioning of the toothed workpiece is simple to operate. The screws 20510 facilitate replacement of the angular blocks 2059 on the cylinders 2058, thereby avoiding the inconvenience of replacing the severely worn angular blocks 2059.

[0026] like Figure 4 As shown, a support rod 2053 is fixedly connected to the surface of the conveying frame 1, and the inner wall of the rack 203 is slidably connected to the surface of the support rod 2053. A stopper 2054 is fixedly connected to the surface of the support rod 2053. The diameter of the stopper 2054 is larger than the diameter of the support rod 2053. The support rod 2053 is used to support and limit the rack 203 to prevent the rack 203 from having no support point, resulting in the rack 203 and the gear 204 being unable to mesh and rotate. The stopper 2054 limits the moving rack 203 to prevent the rack 203 from detaching from the surface of the gear 204 during movement, thereby ensuring the stability of the meshing and rotation of the rack 203 and the gear 204.

[0027] When the utility model is in use, when it is necessary to load the toothed workpiece, the toothed workpiece is placed on the positioning fixture 4, and the positioning fixture 4 is placed on the conveyor belt 3, and the servo motor 2051 is started. The output shaft of the servo motor 2051 rotates to drive the gear 204 to rotate and drive the conveyor belt 3 to transmit. The conveyor belt 3 drives the positioning fixture 4 to move. The gear 204 rotates through the rack 203 to drive the movable frame 202 to move. The movable frame 202 squeezes the spring 2055 during the movement. The movable frame 202 moves to drive the positioning plate 201 to move. The spring 2055 is used to increase the resistance of the positioning plate 201 to move, thereby reducing the impact force of the ball 2052 on the positioning fixture 4, so that the ball 2052 can gently contact the positioning fixture 4, and the positioning plate 201 moves to drive the positioning plate 201 to move, so that the two positioning plates 201 It approaches the ball 2052 and interferes with the positioning tool 4 to limit it, ensuring that the positioning tool 4 will not deviate when moving to the angular structure, thereby improving the accuracy of angular positioning. It can interfere with and limit positioning tools 4 of different sizes, thereby improving the diversity of using the anti-deviation mechanism 2. The ball 2052 is used to reduce the resistance encountered by the positioning tool 4 during movement. When the positioning tool 4 moves to a suitable position, one end of multiple cylinders 2058 moves in sequence to drive their respective angular blocks 2059 to move toward the work pallet. When one of the angular blocks 2059 extends out and interferes with the toothed workpiece in place, it is determined that the angular positioning is successful, and the subsequent cylinder 2058 no longer moves. After the angular positioning is successful, the robot calls the corresponding path program to grab it, ensuring that the workpiece posture is consistent during loading, thereby improving the loading effect of the toothed workpiece, and the angular positioning of the toothed workpiece is simple to operate.

[0028] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
