Description

Technical Field

[0001] The invention relates to the technical field of motor shaft processing, in particular to an automatic motor shaft material sorting and feeding device. Background Art

[0002] During the processing of the motor shaft, a rod-shaped workpiece is used as the raw material. Rough turning is first performed, and the material diameter is gradually reduced to the required size through the lathe. This is followed by precision grinding. The grinder is used to improve the surface accuracy and dimensional accuracy of the shaft. Then, precision machining is performed, including boring, keyway grinding, etc., in order to install bearings or connectors. Finally, strict dimensional measurement and quality inspection are carried out to ensure that the shaft meets the design requirements and quality standards.

[0003] As the instruction manual Fig.10 As shown, it is a motor shaft of a certain model of motor, and the motor shaft includes a shaft body portion 01 and an end portion 02, and the whole is a stepped shaft with a large head at one end. After the motor shaft is processed, it needs to be transferred from the turning production line to the quenching equipment for quenching treatment at the end portion 02.

[0004] This process is traditionally performed by manual loading. After the motor shaft is processed on the automatic lathe, it falls into a material frame, and then the staff transfers the material frame to the quenching equipment.

[0036] The material processing table 12 is provided with an inner cavity 122 (such as Figure 6 As shown), a limiting groove 121 communicating with the inner cavity 122 is provided at the top, the width of the limiting groove 121 is larger than the diameter of the shaft body 01 and smaller than the diameter of the end head 02, a second conveying mechanism 4 for pushing the motor shaft to move is provided in the inner cavity 122, a third conveying mechanism 6 is provided on the side of the material sorting table 12, a discharge notch 123 is provided on the side of the material sorting table 12 and at a position corresponding to the third conveying mechanism 6, a material guiding mechanism 5 is provided on the top of the material sorting table 12 for pulling the shaft body 01 of the conveying motor shaft into the limiting groove 121, and when the motor shaft transported by the first conveying mechanism 3 reaches the top of the material sorting table 12, the material guiding mechanism 5 can be used to gradually pull the motor shaft to extend in the same direction as the limiting groove 121 In a parallel state, the motor shaft rolls, and finally the shaft body 01 of the motor shaft falls into the limiting groove 121, and the lower part of the end head 02 contacts the end faces of the top of the sorting table 12 on both sides of the limiting groove 121, so that the motor shaft is suspended and arranged, and it is ensured that the end head 02 of each motor shaft is facing upward, so as to realize the sorting of the motor shaft, and then the second conveying mechanism 4 is used to push the suspended motor shaft along the limiting groove 121 to the side of the discharge gap 123, and the suspended motor shaft finally falls on the third conveying mechanism 6 through the discharge gap 123, and it is ensured that the arrangement direction of each motor shaft is consistent, and then the motor shaft is conveyed to the next process by the third conveying mechanism 6 for processing, so as to realize the feeding of the motor shaft.

[0037] See also Figure 2 , Figure 3 and Figure 4 The inner bottom wall of the silo 111 is an inclined surface, and the bottom is provided with a trough 112. The pushing mechanism 2 includes an electric push cylinder 21, a support arm 22, an inclined support plate 23 and a blocking plate 24. A mounting cavity 201 extending vertically and communicating with the trough 112 is provided in the material holding platform 11. The electric push cylinder 21 is vertically fixed on the inner bottom wall of the mounting cavity 201, and the support arm 22 is vertically fixed on the end of the telescopic rod of the electric push cylinder 21. The top of the support arm 22 extends into the trough 112 and is fixed with an inclined support plate 23. The blocking plate 24 is fixed on one side of the inclined support plate 23. One end of the inclined support plate 23 away from the blocking plate 24 is slidably fitted with the inner wall of the silo 111, and the blocking plate 24 is slidably fitted with the inner wall of the trough 112. A material storage trough 231 is formed between the inclined support plate 23 and the inner wall of the silo 111, and the material storage trough 231 can only accommodate a single motor shaft.

[0038] When the electric push cylinder 21 retracts and resets, the inclined support plate 23 is in the trough 112. Since the bottom of the silo 111 is tilted, the motor shaft at the bottom of the silo 111 will roll into the material storage trough 231 formed between the inclined support plate 23 and the inner wall of the silo 111. Then, the electric push cylinder 21 extends and its output shaft, under the connection action of the support arm 22, pushes the inclined support plate 23 and the sealing plate 24 to slide upward as a whole until the inclined support plate 23 is separated from the inner wall of the silo 111, at which time the material storage trough 231 disappears. In addition, since the inclined support plate 23 is arranged inclined, the motor shaft eventually rolls sideways along the inclined support plate 23 to the first conveying mechanism 3, and then the electric push cylinder 21 retracts to drive the inclined support plate 23 and the sealing plate 24 to move down and reset, and then the above steps are repeated to realize the lifting and conveying of a single motor shaft.

[0039] In addition, the blocking plate 24 rises and falls synchronously with the inclined support plate 23, especially when the inclined support plate 23 moves upward to the extreme position, the blocking plate 24 moves upward synchronously with the inclined support plate 23. At this time, the side surface of the blocking plate 24 fits with the side surface of the material holding table 11, which has a blocking effect and prevents the motor shaft from rolling into the trough 112 and causing jamming.

[0040] The first conveying mechanism 3 includes a first mounting frame 31, a first conveyor belt 33 and a pair of first shaft rollers 32. The first mounting frame 31 is mounted on the side of the material holding platform 11. The two first shaft rollers 32 are rotatably mounted on the first mounting frame 31 respectively. The first conveyor belt 33 is sleeved on the two first shaft rollers 32. Two third baffles 311 distributed in an inverted eight-shaped shape are symmetrically arranged on the top of the first mounting frame 31 and on both sides of the first conveyor belt 33. A material guide slope 113 is provided on the top of the material holding platform 11 near the first conveyor belt 33. First baffles 1131 are provided on both sides of the material guide slope 113. A material guide notch 312 for the power supply shaft to fall from the material guide slope 113 to the first conveyor belt 33 is provided on the third baffle 311 near the material guide slope 113. One end of the first conveyor belt 33 is connected to the material guide slope 113, and the other end is connected to the upper end of the material sorting platform 12.

[0041] The motor shaft is pushed to the side of the material receiving table 11 by the inclined support plate 23, passes through the material guide slope 113 and the material guide notch 312 and rolls onto the first conveyor belt 33. The first baffle 1131 is used to prevent the motor shaft from slipping off the two sides of the material guide slope 113. The extension direction of the material storage groove 231 is consistent with the conveying direction of the first conveyor belt 33. The two third baffles 311 arranged on the top of the first mounting frame 31 have a blocking and limiting effect on the motor shaft, ensuring that the motor shaft is centered and in contact with the first conveyor belt 33 to generate friction so that it can be conveyed normally.

[0042] See also Figure 1 , Figure 5 , Figure 6 and Figure 7 Two second baffles 124 are symmetrically arranged in an inverted eight-shaped shape at the top of the material sorting table 12 and on both sides of the limiting groove 121. The two second baffles 124 can limit the motor shaft that falls on the top of the material sorting table 12 to prevent the motor shaft from sliding off the side of the top of the material sorting table 12, and the inclined second baffles 124 can assist the motor shaft to roll toward the limiting groove 121 at the center of the top of the material sorting table 12.

[0043] The material guiding mechanism 5 includes an inclined material guiding seat 51, a traction belt 53, a driving motor 54 and a pair of rollers 52. The inclined material guiding seat 51 is arranged on the top of the material sorting table 12 and is located on one side of the limiting groove 121. The side surface of the inclined material guiding seat 51 facing the limiting groove 121 is provided with a side groove 511. The two rollers 52 are rotatably installed on both sides of the side groove 511 respectively. The traction belt 53 is sleeved on the two rollers 52. The driving motor 54 is fixed on the top of the inclined material guiding seat 51, and the output shaft is fixedly connected to one of the rollers 52. When the driving motor 54 works, its output shaft drives one of the rollers 52 to rotate, thereby pulling the traction belt 53 to operate.

[0044] The conveying direction of the first conveyor belt 33 is perpendicular to the extension direction of the limit groove 121, and the motor shaft conveyed to the material sorting table 12 by the first conveyor belt 33 first remains perpendicular to the limit groove 121 until the end of the motor shaft contacts the running traction belt 53. Under the action of friction, the traction belt 53 can pull the motor shaft to deflect and roll until it is parallel to the extension direction of the limit groove 121. Finally, the shaft body 01 of the motor shaft falls into the limit groove 121, and the lower part of the end head 02 conflicts with the end faces on both sides of the limit groove 121 on the top of the material sorting table 12, so that the motor shafts are arranged in a suspended manner, thereby ensuring that the end heads 02 of each motor shaft are facing upward.

[0045] See also Figure 6 The second conveying mechanism 4 includes a second shaft roller 41, a third shaft roller 42, a second conveyor belt 43 and a push plate 44. The second shaft roller 41 and the third shaft roller 42 are rotatably installed on both sides of the inner cavity 122 respectively. The second conveyor belt 43 transmission sleeve is on the second shaft roller 41 and the third shaft roller 42. A plurality of push plates 44 are arranged at equal intervals on the second conveyor belt 43. A limiting space 441 for inserting the shaft body 01 is formed between two adjacent push plates 44. After the shaft body 01 of the motor shaft falls into the limiting groove 121, as the second conveyor belt 43 runs, the shaft body 01 finally falls into the limiting space 441. The push plate 44 is driven to move by the operation of the second conveyor belt 43. The push plate 44 can push the motor shaft to move along the limiting groove 121 to the side where the discharge notch 123 is located, and each limiting space 441 can only accommodate one shaft body 01, thereby realizing the orderly arrangement and transportation of the motor shaft.

[0046] The ends of the push plates 44 are all arc-shaped, so when the end of the shaft body 01 contacts the end of the push plate 44, jamming can be avoided.

[0047] In addition, if Figure 5 and Fig.11 As shown, the upper end surface of the material sorting table 12 is provided with mounting grooves 125 on both sides of the limiting groove 121, and a plurality of rotatable guide rollers 1251 are arranged in an array along the length direction of the limiting groove 121 in the two mounting grooves 125. When the shaft body 01 falls into the limiting groove 121 and is inserted into the limiting space 441, the lower end of the end head 02 contacts the guide rollers 1251 on both sides of the limiting groove 121, and when the pushing plate 44 pushes the motor shaft forward, the guide rollers 1251 roll to reduce the friction on the end head 02 and ensure that the motor shaft moves more smoothly and stably.

[0048] As the instruction manual Figure 8 As shown, the third conveying mechanism 6 includes a second mounting frame 61, a third conveyor belt 63, a pair of fourth shaft rollers 62 and a plurality of clamping plates 64. The second mounting frame 61 is fixed to the side of the material sorting table 12, one of the fourth shaft rollers 62 is rotatably mounted on the second mounting frame 61, and the other fourth shaft roller 62 is rotatably mounted in the inner cavity 122. The third conveyor belt 63 is transmission-sleeved on the two fourth shaft rollers 62, and one end thereof passes through the discharge notch 123 and extends into the inner cavity 122. An inclined extrusion block 126 is provided on the inner side wall of the inner cavity 122 and is located below the limiting groove 121. The inclined surface of the inclined extrusion block 126 can be used to push the motor shaft into the discharge notch 123. As the motor shaft is pushed and transported along the limit groove 121 until it reaches the discharge notch 123, the bottom end of the shaft body 01 is located above the third conveyor belt 63. The inclined surface of the inclined surface extrusion block 126 is used to extrude the shaft body 01, gradually pushing the motor shaft to gradually tilt toward the side where the discharge notch 123 is located, and finally passing through the discharge notch 123 and swinging from a vertical hanging state to a horizontal state, and falling on the third conveyor belt 63. It is ensured that when each motor shaft falls on the third conveyor belt 63, the end head 02 is ensured to face the side away from the material sorting table 12, so that the motor shafts are arranged in order. By operating the third conveyor belt 63, the motor shafts can be arranged in order and transported to the next process.

[0049] By arranging the material holding table 11, the first conveying mechanism 3, the material sorting table 12 and the third conveying mechanism 6 and other components in sequence, the motor shaft can be arranged in a specified direction to achieve an automatic material sorting effect, and the motor shaft can be automatically fed to the next processing step. Compared with traditional manual feeding, it has a high degree of automation, saves time and effort, and improves processing efficiency.

[0050] In addition, two fourth baffles 611 are symmetrically arranged in an inverted figure eight shape on the second mounting frame 61 and located on both sides of the third conveyor belt 63. The two fourth baffles 611 are used to limit the motor shaft that falls on the third conveyor belt 63. The inclined characteristics of the fourth baffles 611 are used to make the motor shaft roll and be centered on the third conveyor belt 63.

[0051] In conjunction with the instruction manual Fig.12 , several card plates 64 are arranged at equal intervals on the third conveyor belt 63, and each card plate 64 is evenly provided with a card slot 641 for the shaft body 01 to match and snap into, and the caliber size of the card slot 641 is smaller than the diameter of the end head 02. When the motor shaft falls on the third conveyor belt 63 and is centered, the shaft body 01 fits into the card slot 641, and the size of the end head 02 is larger than the size of the card slot 641. As the third conveyor belt 63 runs, the card plate 64 can be driven to collide with the end head 02, and then the card plate 64 can be used to drive the entire motor shaft forward to realize the feeding of the motor shaft. In addition, the card plates 64 are arranged at equal intervals to ensure that the motor shafts are evenly distributed on the third conveyor belt 63, which is beneficial to the consistency of the later feeding intervals.

[0052] The limiting space 441 between two adjacent push plates 44 is only for the insertion of a single shaft body 01, so that when the motor shaft moves and is transported along the limiting groove 121 to the side of the discharge notch 123, the spacing is evenly distributed without collision interference. The evenly distributed clamping plates 64 and the clamping holes 641 thereon ensure that the third conveyor belt 63 ensures the consistency of the material spacing when transporting the motor shaft, which is beneficial to the consistency of the subsequent feeding intervals and prevents the accumulation of materials or uneven spacing during the transmission process that requires shutdown adjustments, thereby ensuring the smooth progress of the subsequent feeding process and improving the overall production efficiency. In addition, the control of the material gap does not rely on complex sensors or control mechanisms, which reduces the investment in equipment costs and makes the material transportation management simpler and more efficient.

[0053] See also Figure 1 and Fig. 9 The material sorting and feeding device also includes a first bracket 13, a main shaft 14, a driving mechanism 7, a first linkage mechanism 8, a second linkage mechanism 801 and a third linkage mechanism 9. The main shaft 14 is rotatably mounted on the side of the material sorting platform 12 through two first brackets 13. The driving mechanism 7 is arranged on the side of the material sorting platform 12, and is used to drive the main shaft 14 to rotate. The first linkage mechanism 8 is transmission-connected between the end of the main shaft 14 and the third shaft roller 42, and is used to drive the third shaft roller 42 to rotate when the main shaft 14 rotates. The second linkage mechanism 801 is transmission-connected between the main shaft 14 and one of the first shaft rollers 32, and is used to drive the first shaft roller 32 to rotate when the main shaft 14 rotates. The third linkage mechanism 9 is transmission-connected between the second shaft roller 41 and one of the fourth shaft rollers 62, and is used to drive the fourth shaft roller 62 to rotate when the second shaft roller 41 rotates.

[0054] Specifically, the driving mechanism 7 includes a fixed base 71 fixed on the side of the material sorting table 12, a driving motor 72 fixed on the fixed base 71, a main gear 73 fixed on the output shaft of the driving motor 72, and a driven gear 74 fixed on the main shaft 14. The driven gear 74 is meshed with the main gear 73. When the driving motor 72 works, its output shaft drives the main gear 73 to rotate. The rotating main gear 73 meshes with the driven gear 74 and drives the main shaft 14 to rotate, providing drive for the rotation of the main shaft 14.

[0055] The first linkage mechanism 8 includes a first rotating shaft 81 fixed on the third shaft roller 42, a first bevel gear 82 fixed on the end of the first rotating shaft 81, and a second bevel gear 83 fixed on the end of the main shaft 14. The first bevel gear 82 is meshed with the second bevel gear 83. When the main shaft 14 rotates, it can drive the second bevel gear 83 to rotate. The rotating second bevel gear 83 can mesh with the first bevel gear 82 and drive the first rotating shaft 81 to rotate. Then, the first rotating shaft 81 drives the third shaft roller 42 to rotate. Figure 6 The rotating third shaft roller 42 pulls the second conveyor belt 43 to operate, and at the same time drives the second shaft roller 41 on the other side to rotate, providing drive for the operation of the second conveyor belt 43.

[0056] The second linkage mechanism 801 includes a first pulley 84 fixedly mounted on the main shaft 14, a second rotating shaft 85 fixedly mounted on the end of one of the first shaft rollers 32, a second pulley 86 fixedly mounted on the second rotating shaft 85, and a transmission belt 87 mounted on the first pulley 84 and the second pulley 86. When the main shaft 14 rotates, it can drive the first pulley 84 to rotate, and the rotating first pulley 84 pulls the transmission belt 87 to operate, thereby driving the second pulley 86 and the second rotating shaft 85 to rotate, and then the second rotating shaft 85 drives one of the first shaft rollers 32 to rotate. Figure 4 , and then the first conveyor belt 33 can be driven to operate through the first shaft roller 32, providing drive for the operation of the first conveyor belt 33.

[0057] The third linkage mechanism 9 includes two second brackets 91 fixed to the side of the material receiving platform 11, a third rotating shaft 92 rotatably mounted on the two second brackets 91, a third bevel gear 93 fixed on the third rotating shaft 92, a fourth rotating shaft 94 fixed to the end of one of the fourth shaft rollers 62, and a fourth bevel gear 95 fixed to the fourth rotating shaft 94. One end of the third rotating shaft 92 is fixedly connected to the second shaft roller 41, and the fourth bevel gear 95 is meshed with the third bevel gear 93. Figure 6 and Figure 8When the second conveyor belt 43 is running, it drives the second shaft roller 41 to rotate. The rotating second shaft roller 41 drives the third rotating shaft 92 and the third bevel gear 93 to rotate. The third bevel gear 93 engages and drives the fourth bevel gear 95 and drives the fourth rotating shaft 94 to rotate, thereby driving the fourth shaft roller 62 on one side to rotate. The fourth shaft roller 62 then drives the third conveyor belt 63 to operate, providing drive for the operation of the third conveyor belt 63.

[0058] The present invention sets three linkage mechanisms so that the operation of the first conveyor belt 33, the second conveyor belt 43 and the third conveyor belt 63 share the same driving source, that is, the first conveyor belt 33, the second conveyor belt 43 and the third conveyor belt 63 can be driven to operate simultaneously through the operation of the driving motor 72, without the need to configure multiple driving devices, thereby reducing the investment in equipment costs. In addition, by adjusting the working rotation of the driving motor 72, under the transmission action of the three linkage mechanisms, the rotational speeds of the first conveyor belt 33, the second conveyor belt 43 and the third conveyor belt 63 can be adjusted simultaneously, so that the conveying speed of the entire conveyor line can be regulated at the same time, thereby improving the flexibility and conveying efficiency of the entire conveyor line to meet the needs of different conveying scenarios.
