Description

Technical Field

[0001] The utility model relates to the field of motor production, and particularly relates to a single-chip sorting mechanism for scattered motor iron core chips. Background Art

[0002] With the development of society and technology, the performance and requirements of motors have been improved. Therefore, when manufacturing motor cores, stamping dies are used to punch out loose pieces, and then the punched loose pieces are manually stacked and welded into motor cores. Due to the high labor costs at present, in order to reduce costs and improve product competitiveness, efficiency should be improved as much as possible. Due to the limitations of product characteristics, only single pieces can be made. If a special person is sent to sort the pieces after the single piece is stamped, the efficiency is not high. If a guide cage is used to sort the pieces, problems with the single piece cannot be discovered in time, and must be discovered after the single piece is out of the guide cage, which has a high potential risk. The guide cage takes a long time to disassemble and assemble, which is not suitable for products with small batches.

[0003] To this end, patent CN2017112948070 discloses a single-piece sorting device for loose core pieces of a motor, in which a plurality of ejector pins are arranged, which can extend or retract relative to a blanking hole. When the loose core pieces are dropped, the ejector pins extend relative to the blanking hole to sort the loose core pieces. When the dropped loose pieces reach a set number, the cylinder drives the rotating seat to rotate, and then drives the ejector pins to retract relative to the blanking hole. The sorted loose pieces are output and fall onto a conveyor belt at the same time for transmission and output. However, this structure still has certain defects when used: the ejector pin is a rigid structure. When the rotating seat is stuck or the sensor fails to sense the number of loose pieces and fails to drive the cylinder, the loose pieces that have been dropping will impact the ejector pin and the mold cavity, thereby damaging the ejector pin and the mold cavity and causing losses. In addition, since the sensor is arranged, an induction control board and an induction circuit are also required to electrically control the sensor, which is costly and has complex circuits. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a single-chip sorting mechanism for scattered motor core chips which has a simple structure, is not easy to damage and has a lower cost.

[0005] The technical solution adopted by the utility model to solve the above-mentioned problem is: a single-piece sorting mechanism for loose pieces of motor core, comprising a base, an annular drawer plate, a connecting plate, and a driving assembly, wherein the connecting plate is arranged on the upper part of the base, the annular drawer plate is rotatably arranged between the base and the connecting plate, the driving assembly drives the annular drawer plate to rotate forward or reversely, a through blanking hole is arranged in the center of the base, the annular drawer plate, and the connecting plate, the base is circumferentially provided with a plurality of sinking grooves connected with the blanking hole, a slider base, a slider movable block, and an elastic member are arranged in the sinking groove, the slider movable block is rotatably arranged on the slider base, the elastic member is arranged between the slider movable block and the slider base, the slider base is connected to the annular drawer plate, and the annular drawer plate drives the slider base to move so as to make the slider movable block extend or retract toward the blanking hole.

[0006] Compared with the prior art, the utility model has the following advantages: in the process of sorting the scattered sheets, the driving component drives the annular drawer to rotate forward, the annular drawer drives the slider base and at the same time drives the slider movable block to extend relative to the blanking hole and catch the scattered sheets; when the scattered sheets reach the set number, the driving component drives the annular drawer to reverse, the annular drawer drives the slider base to retract into the sink groove and at the same time the slider movable block retracts relative to the blanking hole and no longer limits the scattered sheets after the sorting is completed. The scattered sheets after the sorting are downwardly dropped onto the conveyor belt for transmission and output; at the same time, the slider movable block rotates with the slider base and an elastic member is arranged between the two, so that the sheet sorting process When the annular drawer is stuck or the cylinder does not receive a signal and drives the slider movable block to retract relative to the blanking hole, the loose pieces that are still being dropped will overcome the elastic force of the elastic part and drive the slider movable block to rotate downward, and the slider movable block will no longer limit the loose pieces, thereby avoiding continuous impact on the slider movable block or the mold cavity around the blanking hole and causing damage, which is safer. Furthermore, the operator only needs to observe whether the loose pieces on the conveyor belt are the standard number of pieces to know whether the sheet sorting mechanism is stuck. There is no need to set sensors and related sensing control components, which is lower in cost and simpler in structure.

[0007] Furthermore, a connecting hole is provided at the rear of the slider base, the annular drawer plate is provided with an inclined long waist hole, a driving pin is provided between the slider base and the annular drawer plate, the upper part of the driving pin is provided in the long waist hole, and the lower part of the driving pin is provided in the connecting hole.

[0008] Furthermore, the elastic member is a torsion spring, and the front part of the slider base is rotatably connected to the slider movable block via a rotating shaft, and the rotating shaft is arranged at the lower part of the slider movable block. The torsion spring includes a main body, a first elastic end, and a second elastic end, and the main body is sleeved on the rotating shaft, the first elastic end is abutted against the slider base, and the second elastic end is abutted against the slider movable block.

[0009] Furthermore, the driving assembly includes a cylinder and a pull rod, the cylinder is connected to the base, the base is provided with a driving groove for the pull rod to translate, the pull rod is fixed on the output shaft of the cylinder, the side wall of the annular pull plate is provided with a protrusion, and one side of the pull rod is provided with a groove for engaging with the protrusion.

DETAILED DESCRIPTION

[0018] like Figures 1 to 6 As shown,

[0019] A single-chip sorting mechanism for loose sheets of motor core comprises a base 1, an annular drawer plate 2, a connecting plate 3 and a driving assembly 4. The connecting plate 3 is arranged on the upper part of the base 1. The annular drawer plate 2 is rotatably arranged between the base 1 and the connecting plate 3. The driving assembly 4 drives the annular drawer plate 2 to rotate forward or reversely. A through blanking hole 5 is arranged in the center of the base 1, the annular drawer plate 2 and the connecting plate 3. The base 1 is circumferentially provided with a plurality of sinking grooves 1.1 connected with the blanking hole 5. A slider base 6, a slider movable block 7 and an elastic member 8 are arranged in the sinking groove 1.1. The slider movable block 7 is rotatably arranged on the slider base 6. The elastic member 8 is arranged between the slider movable block 7 and the slider base 6. The slider base 6 is connected to the annular drawer plate 2. The annular drawer plate 2 drives the slider base 6 to move so as to extend or retract the slider movable block 7 toward the blanking hole 5.

[0020] Among them, the rear part of the slider base 6 is provided with a connecting hole 6.1, the annular draw plate 2 is provided with an inclined long waist hole 2.1, and a driving pin 9 is provided between the slider base 6 and the annular draw plate 2. The upper part of the driving pin 9 is arranged in the long waist hole 2.1, and the lower part of the driving pin 9 is arranged in the connecting hole 6.1. After the driving component 4 drives the annular draw plate 2 to rotate, the inclined long waist hole 2.1 drives the slider base 6 to move radially along the base 1 through the driving pin 9. The specific principle is as follows: Figure 2 and Figure 4When the driving pin 9 moves in the obliquely arranged long waist hole 2.1, the distance from the center of the annular drawer plate 2 on the annular drawer plate 2 will change, and at the same time, the driving pin 9 is limited by the connecting hole 6.1 of the slider base 6 and can only move along the radial direction of the base 1. Therefore, when the driving component 4 drives the annular drawer plate 2 to rotate, the driving pin 9 can drive the slider base 6 to move along the radial direction of the base 1, thereby driving the slider movable block 7 to extend or retract relative to the blanking hole 5.

[0021] Among them, the elastic member 8 is a torsion spring, the front part of the slider base 6 and the slider movable block 7 are rotatably connected through a rotating shaft 10, the rotating shaft 10 is arranged at the lower part of the slider movable block 7, the torsion spring includes a body 8.1, a first elastic end 8.2, and a second elastic end 8.3, the body 8.1 is sleeved on the rotating shaft 10, the first elastic end 8.2 is against the slider base 6, and the second elastic end 8.3 is against the slider movable block 7, and the slider movable block 7 can be rotated downward relative to the sliding base. Specifically, under normal conditions, such as Figure 3 and Figure 5 In the embodiment, the torsion spring drives the slider movable block 7 to be in a horizontal state. When the slider movable block 7 extends relative to the blanking hole 5, the weight of the loose pieces is less than the elastic force of the torsion spring, that is, the gravity of the conventional loose piece blanking is less than the elastic force of the torsion spring and will not drive the slider movable block 7 to rotate. When a certain number of loose pieces fall, and the annular drawer 2 is stuck or the driving component 4 does not drive the annular drawer 2 to move, and the slider movable block 7 does not retract relative to the blanking hole 5, the loose pieces fill the entire blanking hole 5, and the upper die that continues to punch will impact downward and push the slider movable block 7 to overcome the elastic force of the torsion spring and rotate downward, so that Figure 6 As shown, the slider is rotated back into the base 1 to avoid directly damaging the slider movable block 7 and also avoid damaging the mold cavity around the blanking hole 5.

[0022] Among them, the driving component 4 includes a cylinder 4.1 and a draw rod 4.2. The cylinder 4.1 is connected to the base 1. A driving groove 1.2 for the draw rod 4.2 to translate is provided in the base 1. The draw rod 4.2 is fixed on the output shaft of the cylinder 4.1. A protrusion 2.2 is provided on the side wall of the annular draw plate 2. A groove 4.2.1 for engaging with the protrusion 2.2 is provided on one side of the draw rod 4.2. After the cylinder 4.1 drives the draw rod 4.2 to translate, the groove 4.2.1 on the draw rod 4.2 can drive the protrusion 2.2 to move, and the protrusion 2.2 can drive the annular draw plate 2 to rotate, and the cylinder 4.1 is pushed out. The drive is simple and the structure is reliable. It is a prior art and will not be repeated here.

[0023] The number of the sinking grooves 1.1 is 3 to 8. By arranging a plurality of sinking grooves 1.1 and arranging a set of slider bases 6 and slider movable blocks 7 in each sinking groove 1.1, the falling scattered pieces can be supported more stably and the pieces can be arranged more neatly.

[0024] The above description is only for the best embodiment of the utility model, but it cannot be understood as a limitation of the claims. The utility model is not limited to the above embodiments, and its specific structure is allowed to be changed. All changes made within the protection scope of the independent claims of the utility model are within the protection scope of the utility model.
