Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of machining, in particular to a feeding device for machining. BACKGROUND

[0002] The pulley belongs to the hub type parts, and is widely used in long distance power transmission occasions. The pulley is mainly obtained by machining the blank. In the traditional pulley blank machining process, the blank is screened by detecting mechanism or artificial judgment, and the unqualified blank is screened out for recycling to process other specifications of pulley, so as to reduce the cost and waste.

[0003] At present, the pulley feeding device detects the blank on the conveying module through the detection module, then pushes out the unqualified blank from the conveying module and collects it, and then puts the blank meeting the size range into the material receiving disc, so as to complete the feeding work. However, only the unqualified blank is directly pushed out of the conveying module, resulting in mixing of the blanks that are too large or too small, and size screening is still needed in subsequent reprocessing, which greatly reduces the work efficiency. Moreover, the existing pulley feeding device uses a mechanical hand to place the blank into the material receiving disc. However, due to the uncertainty caused by blank screening, the blank actually produces intermittent interruption in the conveying process, so that the mechanical hand may not be able to timely grasp the blank, resulting in the blank falling after touching the end of the conveying module, and causing damage to the blank or the conveying module. SUMMARY

[0004] The technical problem to be solved by the present application is to provide a feeding device for machining, which solves the problems of the existing pulley feeding device that the unqualified blank needs secondary screening and the irregular interruption in the blank conveying process caused by screening, affecting the grasping of the mechanical hand.

[0009] In one embodiment, a trigger slider and a trigger cavity are provided in the buffer ball head, one end of the trigger slider abuts against the trigger button, and the other end of the trigger slider slides along the trigger cavity. A trigger spring is provided between the end of the trigger slider close to the trigger button and the buffer ball head.

[0010] In one embodiment, the trigger slider is in the shape of an "I" as a whole, a piezoelectric sensor is provided at the end of the trigger cavity, a pressure plate is provided at the end of the trigger slider away from the trigger button, and a pressure spring is provided between the pressure plate and the trigger slider.

[0011] In one embodiment, the clamping mechanism includes a telescopic rod, a receiving plate, a transmission connecting rod and a clamping arc plate.

[0013] In an embodiment, the transmission connecting rod is in an overall L shape, the corner of the transmission connecting rod is hingedly connected to the conveying module, and the two ends of the transmission connecting rod are respectively connected to the receiving plate and the outer side of the clamping arc plate.

[0015] In an embodiment, the bearing module comprises a material receiving disc, a bearing conveying mechanism and a discharging mechanism, the material receiving disc is placed on the bearing conveyor, the bearing conveying mechanism conveys the material receiving disc to the working position of the manipulator and then to the discharging mechanism after the placement of the material receiving disc is completed.

[0016] In an embodiment, the two sides of the main slide are provided with inclined guide plates, and the connection between the main slide and the first sub-slide or the second sub-slide is provided with a buffer block.

[0017] The present application has the following beneficial effects:

[0018] In the conventional belt wheel blank loading device, after the out-of-range blanks are detected, they are simply removed and stacked, which can ensure the processing of the belt wheel of the next stage is not affected, but when the out-of-range blanks need to be processed, due to the mixed stacking of blanks that are too large or too small, re-screening is still needed, which greatly reduces the efficiency of subsequent processing.

[0019] Therefore, the present application further screens the out-of-range blanks through the sorting module, the degree of extrusion of the trigger buffer mechanism is different for blanks of different diameters, so as to control the rotation of the screening turn plate in different directions, so that the blank is guided into the first sub-slide or the second sub-slide after touching the screening turn plate, and the screening is completed. The sorting module can directly judge the diameter of the blank during the descending process through mechanical action, the overall judgment process is stable and reliable, has stronger stability and efficiency compared with visual detection equipment, and has low cost and simple maintenance. At the same time, the trigger buffer mechanism is electrically connected with the push-up module, so that the push-up module can obtain the feedback of the trigger buffer mechanism, and the push-up module resets when the blank extrudes the trigger buffer mechanism, so as to ensure that the out-of-range blanks can be stably discharged and do not affect the normal conveying of qualified blanks, avoiding the influence of the start and stop of the conveying module on the discharging process of the out-of-range blanks.

[0020] And, since the main slide is inclined as a whole, the embryo material may be hit on the outer edge due to too high speed when sliding along the main slide, the trigger buffer mechanism extending from the side wall of the main slide to the inside of the main slide is arranged, the embryo material touches and presses the trigger buffer mechanism during sliding along the main slide, so that the speed of the embryo material can be greatly reduced, buffering is formed, and the embryo material is prevented from being hit. At the same time, the embryo material is prevented from impacting the main slide, the first branch slide and the second branch slide, the deformation of the slide structure is avoided, and the service life of the whole device is improved.

[0021] After the sorting module is arranged, although the embryo material out of range can be pushed out, due to the uncertainty of the overall size distribution of the embryo material, the embryo material is interrupted after being pushed out during continuous conveying, and the detection accuracy of the mechanical hand is high, and the overall use and maintenance cost is high. Therefore, the blocking module is used for guiding and clamping the embryo material, the clamping mechanism triggers the clamping action when the embryo material is continuously displaced forward under the action of the conveying module to press the clamping mechanism, and the signal is transmitted to the mechanical hand and the conveying module, so that the conveying module stops running, the mechanical hand clamps and carries, the bottom of the embryo material is prevented from being continuously affected by the conveying module after the embryo material abuts against the guide arc plate, the bottom of the embryo material is prevented from being scratched, the clamping mode can prevent the embryo material from being poured, the positioning accuracy is improved, the difficulty of clamping of the mechanical hand is reduced, and the overall efficiency is effectively improved.

DETAILED DESCRIPTION

[0035] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the technical solutions in the embodiments of the present application to make a clear and complete description. Obviously, the described embodiments are some but not all of the embodiments of the present application. As long as there is no conflict, the technical features in the different embodiments of the present application can be combined with each other. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0036] In the description of the present application, it should be noted that all the terms (including technical terms and scientific terms) used in the present application have the same meaning as that generally understood by the ordinary skilled person in the field to which the present application belongs, and cannot be understood as a limitation on the present application; it should be further understood that the terms used in the present application should be understood as having the same meaning as the terms in the context of the present application and the related field, and should not be understood in an idealized or overly formal sense, unless otherwise defined in the present application.

[0037] To explain the technical content, purposes and effects of the present application in detail, the following embodiments are described in conjunction with the accompanying drawings.

[0038] Please refer to Figures 1 to 10 A feeding device for machining, comprising a manipulator 2, a conveying module 1, a bearing module 3, a pushing module 4 and a detection module 5, the conveying module 1 conveying the blank to the front of the bearing module 3, the manipulator 2 placing the blank into the bearing module 3; the detection module 5 is arranged on the conveying module 1 and is used for detecting the size of the blank, the detection module 5 being electrically connected with the pushing module 4; a waste opening 11 is arranged on the side of the conveying module 1 corresponding to the pushing module 4, the pushing module 4 starting to act when the detection module 5 finds the out-of-range blank, and the out-of-range blank being pushed away from the conveying module 1 through the waste opening 11, further comprising:

[0039] A sorting module 6 is arranged on the side of the conveying module 1; the sorting module 6 comprises a main chute 61, a trigger buffer mechanism 62, a screening rotary plate 63, a first sub-chute 64 and a second sub-chute 65, the main chute 61 extending downwardly and obliquely from the waste opening 11, the first sub-chute 64 and the second sub-chute 65 extending reversely from one end of the main chute 61 away from the waste opening 11, and the screening rotary plate 63 being arranged at the junction of the first sub-chute 64 and the second sub-chute 65 and extending into the main chute 61; the trigger buffer mechanism 62 is arranged on the inner side of the main chute 61 and can extend and retract along the width direction of the main chute 61, and the trigger buffer mechanism 62 is electrically connected with the screening rotary plate 63 and the pushing module 4; the screening rotary plate 63 and / or the pushing module 4 act when the out-of-range blank presses the trigger buffer mechanism 62.

[0040] A blocking module 7 is arranged at the end of the conveying module 1 and comprises a clamping mechanism 71 and a guide arc plate 72, the guide arc plate 72 extending arcuately from the two sides of the width direction of the conveying module 1 to the axis of the conveying module 1, and the clamping mechanism 71 being arranged above the guide arc plate 72; the clamping mechanism 71 is electrically connected with the conveying module 1 and the manipulator 2; the blank presses the clamping mechanism 71 under the action of the conveying module 1, so that the clamping mechanism 71 triggers clamping and transmits an electrical signal to the conveying module 1 and the manipulator 2, and then the manipulator 2 and / or the conveying module 1 are started or stopped.

[0041] Specifically, the trigger buffer mechanism 62 transmits a signal to the push module 4 after being pressed, so that the push module 4 resets, and the over-range blank is discharged.

[0042] Specifically, the trigger buffer mechanism 62 transmits a signal to the screening rotary plate 63 according to the extension amount, so that the screening rotary plate 63 rotates, thereby guiding the over-range blank. Taking the first sub-slide 64 as the too-large blank slide and the second sub-slide 65 as the too-small blank slide as an example, the screening rotary plate 63 initially guides the blank to the second sub-slide 65, and when the blank pushes the trigger buffer mechanism 62 to reach the set extension amount, the trigger buffer mechanism 62 transmits a signal to the screening rotary plate 63, so that the screening rotary plate 63 rotates, guides the blank to the first sub-slide 64, and resets after a set time. Further, the first sub-slide 64 is provided with an infrared sensor, and the screening rotary plate 63 resets when the blank blocks the infrared sensor, thereby ensuring the accuracy of sorting and avoiding sorting errors caused by the screening rotary plate 63 not resetting in time.

[0043] Specifically, those skilled in the art can design the corresponding circuit of the sorting module 6 and the blocking module 7 according to the actual design, without specific limitation.

[0044] Specifically, the push module 4 can adopt the form of a telescopic air cylinder driving an L-shaped plate, which blocks the blank and guides the blank to the waste opening 11. The conveying module 1 can adopt a conveyor belt, and those skilled in the art can select appropriate push modules 4 and conveying modules 1 according to needs, without specific limitation.

[0045] In order to ensure that the reset of the push module 4 can be completed in time, and to avoid the qualified blank touching the push module 4 due to the slow reset of the push module 4, the trigger buffer mechanism 62 needs to send a signal to the push module 4 at the initial stage of contact with the over-range blank. The trigger buffer mechanism 62 includes a buffer ball head 621, a buffer spring 622, and a trigger button 623. The side wall of the main slide 61 is provided with a sliding cavity 611, the buffer ball head 621 extends into the main slide 61 from the sliding cavity 611, the trigger button 623 is arranged in the sliding cavity 611, the buffer spring 622 is sleeved outside the trigger button 623, and the buffer ball head 621 abuts against the trigger button 623. In this way, when the buffer ball head 621 moves, the trigger button 623 directly sends a signal to the push module 4. Specifically, the trigger button 623 can adopt a two-stage stepped button, the first stage button triggers the reset of the push module 4, and the second stage button triggers the rotation of the screening rotary plate 63, or the form of separately arranging a trigger device of the screening rotary plate 63 inside the buffer ball head 621, and those skilled in the art can adjust according to needs, without specific limitation.

[0046] Furthermore, a protective shell 612 is provided on the outer edge of the trigger buffer mechanism 62, and a buffer spring 622 and a trigger button 623 are arranged in the protective shell 612. The inner diameter of the protective shell 612 is slightly larger than the diameter of the buffer ball head 621, so that the buffer ball head 621 can slide along the protective shell 612.

[0047] After the buffer ball 621 is pressed against the trigger button 623, if the extension and contraction of the buffer ball 621 exceeds the pressing range of the trigger button 623, the buffer ball 621 will contact the fixed portion of the trigger button 623, which will not only limit the travel of the buffer ball 621, but also, due to the relatively small area of ​​the trigger button 623, it is easy for the buffer ball 621 to be locally over-pressed, causing damage to the buffer ball 621. Therefore, a trigger slider 624 and a trigger cavity 625 are provided within the buffer ball 621. One end of the trigger slider 624 abuts the trigger button 623, and the other end of the trigger slider 624 slides along the trigger cavity 625. A trigger spring is provided between the end of the trigger slider 624 near the trigger button 623 and the buffer ball 621. During the pressure application of the buffer ball head 621, the trigger spring keeps the trigger slider 624 in contact with the trigger button 623. Even if the trigger button 623 is triggered at the first time, after the trigger button 623 reaches the pressing limit, the trigger slider 624 compresses the trigger spring, causing the other end of the trigger slider 624 to slide along the trigger cavity 625, thereby increasing the displacement distance of the buffer ball head 621.

[0048] The triggering form of the two-stage stepped button is adopted. During the long-term use of the buffer ball head 621, it is possible that the first-stage button is pressed and the second-stage button is driven, or a button of a certain stage is stuck during the reciprocating operation, thereby affecting the reset of the ejection module 4 or the wrong rotation of the screening turntable 63, resulting in the inability to carry out sorting normally. Therefore, the trigger point of the screening turntable 63 and the trigger button 623 are offset. The trigger slider 624 is in the shape of an "I" as a whole. A piezoelectric sensor 626 is provided at the end of the trigger cavity 625. A pressure plate 627 is provided at the end of the trigger slider 624 away from the trigger button 623, and a pressure spring 628 is provided between the pressure plate 627 and the trigger slider 624. That is, a piezoelectric sensor 626 is set inside the buffer ball head 621, and a pressure plate 627 equipped with a pressure spring 628 presses against the piezoelectric sensor 626, thereby sending a signal to the screening turntable 63. The pressure spring 628 provides a margin to prevent the pressure plate 627 from excessively pressing the piezoelectric sensor 626 due to excessive stock, thereby improving overall durability. After this arrangement, the buffer ball head 621 compresses the buffer spring 622, the trigger spring, and the pressure spring 628 in sequence during its displacement, dividing the displacement process of the buffer ball head 621 into three sections. Different signals can be sent through the displacement of different sections, thereby controlling the timely action of the screening turntable 63 or the push module 4. At the same time, a three-level buffer is formed as a whole, which decelerates and buffers the stock pushed out of the conveying module 1 while preventing the buffer ball head 621 from being damaged by excessive force, thereby improving the overall service life.

[0049] Specifically, the width of the main slide 61 and the distance that the buffer ball head 621 penetrates into the main slide 61 can be adjusted by those skilled in the art according to the range of the blanks, so that the blanks with the smallest size can compress the buffer ball head 621 and the blanks with the largest size can pass through the main slide 61 and the first sub-slide 64, without specific limitation.

[0050] When the blank is transported to the end by the transport module 1, the transport module 1 will stop continuing to transport after the clamping mechanism 71 triggers clamping, but before the clamping is triggered, the transport module 1 continues to move, and the blank is blocked and guided by the guide arc plate 72. Single brush, because the belt pulley blank of different specifications has different heights, when the blank is high, the blank may be turned over. Therefore, the clamping mechanism 71 needs to clamp the blank from the circumferential direction. The clamping mechanism 71 includes a telescopic rod 711, a receiving plate 712, a transmission connecting rod 713, and a clamping arc plate 714, both ends of the telescopic rod 711 are connected between the side wall of the carrying module 3 and the receiving plate 712, and the telescopic rod 711 is electrically connected with the transport module 1 and the manipulator 2; one end of the clamping arc plate 714 close to the carrying module 3 is hinged on both sides of the transport module 1, the transmission connecting rod 713 is arranged between the receiving plate 712 and the clamping arc plate 714, after the receiving plate 712 is pressed by the blank, the telescopic rod 711 is pressed to send a signal, and at the same time, the clamping arc plate 714 is driven to rotate and clamp the blank through the transmission connecting rod 713.

[0051] In the embodiment, the telescopic rod 711 includes a sleeve part 7111, a sliding rod part 7112, and a telescopic spring 7113, the sleeve part 7111 is internally provided with a telescopic cavity 7114, one end of the sliding rod part 7112 is arranged in the telescopic cavity 7114, the other end of the sliding rod part 7112 is connected with the receiving plate 712, the telescopic cavity 7114 away from the sliding rod part 7112 is provided with a distance sensor 7115, and the telescopic spring 7113 is located between the sleeve part 7111 and the receiving plate 712 and is sleeved on the sliding rod part 7112. The distance sensor 7115 in the telescopic cavity 7114 detects the distance change of the sliding rod part 7112, and transmits the distance signal to the manipulator 2 and the transport module 1.

[0052] Preferably, when the distance sensor 7115 detects that the distance from the sliding rod part 7112 is less than a first set value, the manipulator 2 is turned to the blank clamping position and preliminarily positioned. When the distance sensor 7115 detects that the distance from the sliding rod part 7112 reaches a second set value, the manipulator 2 starts clamping at the same time, and if the distance sensor 7115 detects that the distance from the sliding rod part 7112 reaches the second set value for a set time, the transport module 1 stops transporting. After clamping is completed, the distance between the distance sensor 7115 and the sliding rod part 7112 is greater than the first set value, and the transport module 1 resumes transporting. In this way, it can be ensured that the manipulator 2 has enough time to position and clamp the blank, and when the clamping time of the manipulator 2 is delayed, the transport module 1 stops running, avoiding that the bottom of the blank is scratched by the transport module 1 or avoiding that the transport module 1 is worn.

[0053] Meanwhile, since the conveying module 1 is started and stopped according to whether the blank is clamped by the manipulator 2, the action time of the pushing module 4 cannot be set only by time, and therefore, by cooperation of the pushing module 4 and the trigger buffer mechanism 62, it can be further verified whether the out-of-range blank is pushed out of the conveying module 1, and the sorting effect and the normal conveying can be ensured.

[0054] In the embodiment, the transmission link 713 is in an L shape as a whole; the corner of the transmission link 713 is hinged on the conveying module 1, and the two ends of the transmission link 713 are connected with the receiving plate 712 and the outer side of the clamping arc plate 714 respectively. Specifically, the two ends of the transmission link 713 are provided with sliding grooves, and the receiving plate 712 and the clamping arc plate 714 are connected with the sliding grooves through guide columns.

[0055] Since the qualified blank also has a size fluctuation range, in order to avoid that the fluctuation range causes the clamping mechanism 71 to clamp the blank too tightly or loosely, in the embodiment, the clamping mechanism 71 further includes a clamping sliding plate 715, which is hinged on the side of the clamping arc plate 714 away from the carrying module 3 and extends towards the carrying module 3, and the clamping sliding plate 715 and the clamping arc plate 714 jointly form a clamping cavity, and a clamping spring 716 is arranged in the clamping cavity 717. When clamping, the clamping sliding plate 715 first contacts the blank, and as the blank advances, the rotation angle of the clamping sliding plate 715 increases, the clamping sliding plate 715 is compressed to compress the clamping spring 716, so that the blank is stably clamped and has a movement allowance, thereby the blank can be smoothly taken out after the manipulator 2 clamps the blank, and the blank is prevented from being scratched.

[0056] Further, the end of the clamping sliding plate 715 away from the clamping arc plate 714 is hinged with a rolling sliding plate 718, the movable end of the rolling sliding plate 718 is provided with a ball, and the inner side of the clamping arc plate 714 is provided with a guide groove, and the ball is slidingly connected with the guide groove.

[0057] In the embodiment, the carrying module 3 includes a blank receiving disc 31, a carrying conveying mechanism 32 and a blanking mechanism 33, the blank receiving disc 31 is placed on the carrying conveyor, the carrying conveying mechanism 32 conveys the blank receiving disc 31 to the working position of the manipulator 2, and after the blank receiving disc 31 is placed, it is conveyed to the blanking mechanism 33.

[0058] In order to smoothly guide the pushed-out blank to the trigger buffer mechanism 62, in the embodiment, the two sides of the main slide 61 are provided with inclined guide plates 66, and the connection between the main slide 61 and the first sub-slide 64 or the second sub-slide 65 is provided with a buffer block, so that the blank is not scratched by the edges when sliding in the sorting module 6, the periphery of the blank is prevented from being damaged, and the quality of subsequent processing is ensured.
