Description

Technical Field

[0001] The invention relates to the technical field of rotating shaft parts production, in particular to a rotating shaft D-hole parts positioning and sorting mechanism. Background Art

[0002] The rotating shaft is a shaft that bears both bending moment and torque during rotation. In industrial production, the rotating shaft has different forms. The rotating shaft is composed of multiple parts. In the production and processing of the rotating shaft parts, how to quickly and accurately sort the parts with random inner hole angles neatly and in the same direction has always been a technical problem in this field. Most of the existing sorting mechanisms sort the rotating shaft parts neatly through a vibrating plate and make the rotating shaft parts consistent in direction through a discharge channel. However, the rotating shaft parts are provided with an asymmetric structure. When on the same plane, only one direction of the two directions that differ by 180 degrees is the correct direction. In particular, the moving cam has a special position of the convex hull and can only have a unique correct angle on the same plane. Therefore, how to make the convex hulls on the sorted rotating shaft parts arranged in the correct direction is a problem to be solved. Summary of the invention

[0003] The purpose of the present invention is to provide a shaft D-hole parts positioning and sorting mechanism to solve the problem that the convex hulls on the sorted shaft parts mentioned in the above background technology cannot be arranged in the correct direction.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a rotating shaft D-hole parts positioning and sorting mechanism, comprising a discharge channel, a correction mechanism and a positive and negative limit mechanism, the correction mechanism comprising a lifting mechanism, a motor, a correction pin, a docking block and a traction mechanism, a mounting plate is provided on the telescopic end of the lifting mechanism, and the motor is arranged on the mounting plate, the output shaft of the motor is connected to one end of the correction pin, and the other end of the correction pin is chamfered, a movable groove is provided in the docking block, and a part is arranged in the movable groove, the traction end of the traction mechanism is connected to the docking block, the part is provided with a chamfered hole capable of accommodating the correction pin, and asymmetric flanges are provided on the left and right sides of the part, the positive and negative limit mechanism comprises a limit block and an ejection mechanism, and the limit block is provided with a through groove matching the flange.

[0005] Preferably, it also includes a clamping mechanism, and the clamping mechanism includes a connecting shaft, a mounting seat, a clamping device and a clamping arm, the connecting shaft is connected to the mounting seat, and the mounting seat is provided with a clamping device at one end opposite to the connecting shaft, and the clamping end of the clamping device is connected to the clamping arm.

[0006] Preferably, the ejection mechanism includes two left and right chucks, a ejection needle and a rotating mechanism, the clamping mechanism is located above the ejection needle, and the left and right chucks are located between the ejection needle and the rotating mechanism, the driving end of the rotating mechanism is connected to the left and right chucks, and the ejection needle is located between the left and right chucks.

[0007] Preferably, a cover plate 1 for preventing parts from falling off is provided on the connecting block, and a cover plate 2 for preventing parts from falling off is provided on the two clamps.

[0008] Preferably, the ejector pin is provided with a cross section capable of being inserted into the chamfered hole for limiting the rotation of the part.

[0009] Preferably, the correction pin is moved downward and inserted into the chamfered hole of the part, and the chamfer at the front end of the correction pin is used to guide the part with an error within a certain range until the angle of the product is consistent with that of the correction pin. If the angle error is too large to be inserted, the correction pin is retracted and the motor drives the correction pin to rotate to a set angle before the part is inserted again. After insertion, the part has only two states that differ by 180° in this plane.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1) The present invention has a through slot matching the flange on the limit block. When the correction pin drives the part to pass through the through slot, because the flange is asymmetrically arranged, the through slot can only accommodate the flange with the correct angle to pass through. When the part cannot pass through, the correction pin is driven by the motor to rotate 180°, and the part is driven to rotate so that the angle of the flange is correct and passes through the through slot, thereby achieving that the flanges on the sorted shaft parts are arranged in the correct direction.

[0012] 2) The present invention has a simple structure, low cost, and is easy to use. By repeatedly adjusting the action, continuous production is achieved, thereby improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

If the angle error is too large and cannot be inserted, the correction pin 5 retreats and the motor 2 drives the correction pin 5 to rotate the set angle before it is inserted again. After insertion, the part 13 has only two states with a difference of 180° in this plane. A movable groove is provided in the connecting block 6, and a part 13 is provided in the movable groove. The traction end of the traction mechanism is connected to the connecting block 6. A chamfered hole 14 capable of accommodating the correction pin 5 is provided on the part 13. The correction pin 5 is inserted into the chamfered hole 14 to facilitate the correction of the part 13 and to drive the part 13 to move. Asymmetric flanges 15 are provided on the left and right sides of the part 13. The flanges 15 are for cam-type parts. The positive and negative limit mechanisms include The limit block 8 is connected with the ejection mechanism, and a through slot matching the flange 15 is provided on the limit block 8. When the correction pin 5 drives the part 13 to pass through the through slot, because the flange 15 is asymmetrically arranged, the through slot can only accommodate the flange 15 with the correct angle to pass through. When the part 13 cannot pass through, the motor 2 is required to drive the correction pin 5 to rotate 180°, and drive the part 13 to rotate 180° so that the angle of the flange 15 is correct and passes through the through slot, so that the flanges 15 on the sorted shaft parts are arranged in the correct direction. This mechanism is not only suitable for Figure 3 The positioning order of part 13 in is also applicable to Fig.10 Gasket and Fig.11 Friction plate.

[0029] It also includes a clamping mechanism, and the clamping mechanism includes a connecting shaft, a mounting seat 4, a clamping device and a clamping arm 9. The clamping mechanism is a manipulator in the prior art, which can clamp the part 13 through the clamping arm 9. The connecting shaft is connected to the mounting seat 4, and the mounting seat 4 is provided with a clamping device at one end opposite to the connecting shaft. The clamping end of the clamping device is connected to the clamping arm 9. The ejection mechanism includes left and right clamps 10, a ejection needle 12 and a rotating mechanism. The clamping mechanism is located above the ejection needle 12, and the left and right clamps 10 are located between the ejection needle 12 and the rotating mechanism. The driving end of the rotating mechanism is connected to the left and right clamps 10. The rotating mechanism can be a driving mechanism composed of a motor, or it can be a driving mechanism composed of a motor. It is other rotating mechanisms in the technical field, and the ejector needle 12 is located between the left and right chucks 10. After the part 13 reaches the position of the chuck 10, the correction pin 5 moves up and retreats to the correction position, and the ejector needle 12 is inserted upward into the chamfered hole 14 in the part 13. The rotating mechanism drives the left and right chucks 10 to rotate and open, the ejector needle 12 moves up to the clamping position, the clamping arm 9 moves down to clamp the part 13, the ejector needle 12 returns to its original position, and the chuck 10 rotates and closes. The connecting block 6 is provided with a cover plate 7 for preventing the part 13 from falling off, and the two chucks 10 are provided with a cover plate 2 11 for preventing the part 13 from falling off. The ejector needle 12 is provided with a section that can be inserted into the chamfered hole 14 to limit the rotation of the part 13.

[0030] Working principle: When used Figure 4 As shown, the parts 13 enter the discharge channel 1, are ejected from the discharge channel 1 in sequence, and enter the movable groove in the connecting block 6, as shown in FIG. Figure 5 As shown, the traction mechanism drives the docking block 6 to move to the correction position (below the correction pin 5), as shown in FIG. Figure 6 As shown, the lifting mechanism 3 drives the correction pin 5 to descend, and the chamfer at the front end of the correction pin 5 is used to guide the part 13 with an error within a certain range to the same angle as the correction pin 5. If the angle error is too large and cannot be inserted, the correction pin 5 retreats and the motor 2 drives the correction pin 5 to rotate the set angle and then insert it again. After insertion, the part 13 has only two states with a difference of 180° in this plane, such as Figure 7 As shown, after the correction pin 5 is inserted into the part 13, the cylinder in the device drives the part 13 to move through the through slot of the limit block 8. For cam parts, it is necessary to distinguish again that the flange 15 has only one of the two angles that differ by 180°. The correct one can pass smoothly, and the wrong one returns to the correction position, rotates 180° to the correct position, and passes again. After the part 13 reaches the position of the chuck 10, as shown in FIG. Figure 8 As shown, the correction pin 5 moves up and back to the correction position, the ejector pin 12 is inserted upward into the chamfered hole 14 in the part 13, and the rotating mechanism drives the left and right chucks 10 to rotate and open, as shown in FIG. Fig. 9As shown, the ejector pin 12 moves up to the clamping position, and then the clamping arm 9 moves down to clamp the part 13. At this time, the position of the clamping arm 9 is as shown in FIG. Figure 4 The middle clamping arm 9 is in the position, the ejector needle 12 returns to its original position, and the chuck 10 rotates and closes.
