Description

Technical Field

[0001] This utility model belongs to the field of material feeding technology, specifically relating to a material feeding mechanism for shuttle shell processing. Background Technology

[0002] Currently, automatic lathes typically use robotic arms or ejection mechanisms within spring collets to directly eject products during unloading. However, this method presents some problems in practical applications, such as:

[0003] 1. Using robotic arms is costly and the movements are too complex;

[0004] 2. The ejection mechanism inside the spring collet directly ejects the product, which requires the cutter head module to be moved a large distance, affecting work efficiency. In addition, the product is prone to mixing with iron filings and cutting fluid generated during processing. Utility Model Content

[0005] The purpose of this invention is to provide a blanking mechanism for shuttle shell processing, thereby solving the problems mentioned in the background art. The blanking mechanism for shuttle shell processing provided by this invention has the characteristics of reducing the distance the cutter head module moves away, thus preventing the product from mixing with iron filings and cutting fluid.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a material feeding mechanism for shuttle shell processing, comprising a swing cylinder and a material feeding guide sleeve, wherein a swing arm is connected to the output end of the swing cylinder, a material box is connected to the lower end of the swing arm, a feeding hole is provided at the center of one end of the material box, an opening is provided on one side of the material box, and a box door is hinged at the opening, the box door and the material box are connected by a tension spring, and a protrusion is connected to the box door to limit the movement in conjunction with the material feeding guide sleeve.

[0007] To achieve the connection between the swing arm and the output end of the swing cylinder, the output end of the swing cylinder is further connected to the swing arm via a connecting shaft.

[0008] To achieve circumferential positioning of the swing arm and connecting shaft and ensure the accuracy of the swing angle, a keyway is further provided on the connecting end of the connecting shaft. A corresponding limiting key is provided in the connecting hole at the upper end of the swing arm.

[0009] Furthermore, the cross-section of the material box has a D-shaped structure.

[0010] To ensure that the box door can be opened, the material guide sleeve is further provided with a notch or groove corresponding to the material box.

[0011] To further collect the products, a receiving box is placed at the lower end of the material guide sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. During the unloading process of this utility model, the material box is swung to the spring chuck module by the swing cylinder. The ejection mechanism in the spring chuck module pushes the product into the material box through the feed hole on the end face of the material box. Then, the swing cylinder drives the material box to swing to the discharge guide sleeve. The protrusion limits the box door, so that the box door opens and the product in the material box is poured into the discharge guide sleeve to realize unloading. Compared with the traditional robotic arm unloading, it has the advantages of simple structure and simple operation. Compared with the traditional direct ejection unloading, the movement range of the cutter head module is smaller, which can improve work efficiency. At the same time, it can also avoid the product from mixing with iron filings and cutting fluid.

[0014] 2. The box door and the material box of this utility model are hinged together by a hinge. At the same time, the box door and the material box are also connected by a tension spring. The box door can be automatically opened by the cooperation of the protrusion and the material guide sleeve. When the material box and the material guide sleeve are separated, the box door is automatically closed by the restoring force of the tension spring.

[0015] 3. The connecting end of the connecting shaft of this utility model is provided with a keyway, and the connecting hole at the upper end of the swing arm is provided with a limiting key corresponding to the keyway. By cooperating with the keyway, the circumferential positioning of the swing arm and the connecting shaft is realized, ensuring the accuracy of the swing angle. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figures 1-7 This utility model provides the following technical solution: a material feeding mechanism for shuttle shell processing, including a swing cylinder 1 and a material feeding guide sleeve 6 mounted on the chassis of a spring chuck module 8. A swing arm 3 is connected to the output end of the swing cylinder 1, and a material box 4 is connected to the lower end of the swing arm 3. A feeding hole 42 is provided at the center of one end of the material box 4, and an opening is provided on one side of the material box 4. A door 41 is hinged to the opening. The door 41 and the material box 4 are connected by a tension spring 44. When the door 41 and the material box 4 are closed, the tension spring 44 provides a tension of about 10N. The door 41 is connected to... The device is equipped with a protrusion 43 that cooperates with the material guide sleeve 6 for limiting the movement. The material guide sleeve 6 and the spring chuck module 8 are symmetrically arranged about the output end of the swing cylinder 1. That is, when the swing cylinder 1 drives the material box 4 to swing to the high end on one side, it corresponds to the spring chuck module 8. When the swing cylinder 1 drives the material box 4 to swing to the high end on the other side, it corresponds to the material guide sleeve 6. A solenoid valve is installed on the air end of the swing cylinder 1. The solenoid valve is connected to the PLC controller signal. The swing stroke of the swing cylinder 1 is determined during equipment debugging. The swing cylinder 1 is an Airtac HRQ30 swing cylinder.

[0026] It should be noted that this utility model is applicable to automatic lathes with an ejector mechanism inside the spring collet.

[0027] By adopting the above technical solution, when the material is unloaded, the swing cylinder 1 drives the material box 4 to swing to the spring chuck module 8. The ejection mechanism in the spring chuck module 8 pushes the product into the material box 4. Then, the swing cylinder 1 drives the material box 4 to swing to the discharge guide sleeve 6. The protrusion 43 limits the box door 41, so that the box door 41 opens and the product in the material box 4 is poured into the discharge guide sleeve 6 to realize unloading. Compared with the traditional robotic arm unloading, it has the advantages of simple structure and simple action. Compared with the traditional direct ejection unloading, the removal range of the cutter head module 7 is smaller, which can improve work efficiency. At the same time, it can also avoid the product from mixing with iron filings and cutting fluid. The box door 41 of this utility model is hinged to the material box 4, and the box door 41 is also connected to the material box 4 by a tension spring 44. The box door 41 can be automatically opened by the cooperation of the protrusion 43 and the material guide sleeve 6. When the material box 4 and the material guide sleeve 6 are separated, the box door 41 is automatically closed by the restoring force of the tension spring 44.

[0028] Specifically, the output end of the swing cylinder 1 is connected to the swing arm 3 via a connecting shaft 2.

[0029] By adopting the above technical solution, the connection between the swing arm 3 and the output end of the swing cylinder 1 is realized.

[0030] Specifically, a keyway 21 is provided on the connecting end of the connecting shaft 2. A limiting key 31 corresponding to the keyway 21 is provided in the connecting hole at the upper end of the rocker arm 3.

[0031] By adopting the above technical solution, the circumferential positioning of the swing arm 3 and the connecting shaft 2 is achieved through the cooperation of the limit key 31 and the keyway 21, ensuring the accuracy of the swing angle.

[0032] Specifically, the material guide sleeve 6 is provided with a notch 61 corresponding to the material box 4.

[0033] By adopting the above technical solution, space is provided for the material box 4 so that after the box door 41 comes into contact with the material guide sleeve 6, the material box 4 can still swing a certain distance to ensure that the box door 41 can be opened.

[0034] Example 2

[0035] The difference between this embodiment and embodiment 1 is that, specifically, the cross-section of the material box 4 has a D-shaped structure.

[0036] By adopting the above technical solution, the material box 4 consists of four parts: a semicircular part, two straight parts tangent to the semicircular part, and an opening corresponding to the semicircular part.

[0037] When the box door 41 is closed, the plane of the box door 41 is parallel to the plane of the swing arm 3. The swing arm 3 drives the material box 4 to swing back and forth between the spring chuck module 8 and the material guide sleeve 6. When it swings to the middle position, the swing arm 3 is vertical, that is, perpendicular to the horizontal plane. When it is in the spring chuck module 8 position, there is an angle of about 30° between the swing arm 3 and the vertical plane, so the box door 41 is slightly upward, and the straight line tangent to the semicircle is also upward. The lowest point of the material box 4 is the semicircle. When it is in the material guide sleeve 6 position, there is an angle of about 30° in the opposite direction between the swing arm 3 and the vertical plane, so the box door 41 is slightly downward, and the straight line tangent to the semicircle is also downward. The lowest point of the material box 4 is the intersection of the lower tangent line and the box door 41.

[0038] The advantages of using a D-shaped cross section are:

[0039] (1) The opening is used to install the box door 41, so the shape of the box door 41 is flat and easy to process; the flat box door 41 will be easier to open when it is pushed open.

[0040] (2) When the swing arm 3 is in the position of the spring clamp module 8, the semicircular part is at its lowest point. In this way, the product will fall onto the semicircular part after entering, instead of landing on the box door 41, and the product will not break open the box door 41 and fall out of the material box 4. When the swing arm 3 is in the position of the material guide sleeve 6, the lowest point of the material box 4 is the intersection of the lower tangent line and the box door 41. In this way, the product will roll to the door of the box door 41. As long as the box door 41 is broken open, the product will naturally fall out of the material box 4.

[0041] (3) Due to the presence of the semi-cylindrical surface of the material box 4, there will be no interference or collision between the material box 4 and the material guide sleeve 6.

[0042] Example 3

[0043] The difference between this embodiment and embodiment 1 is that, specifically, a receiving box 5 is placed at the lower end of the material guide sleeve 6.

[0044] The above technical solution is used to collect products.

[0045] In summary, during the unloading process of this utility model, the swing cylinder 1 drives the material box 4 to swing to the spring chuck module 8. The ejection mechanism in the spring chuck module 8 pushes the product into the material box 4. Then, the swing cylinder 1 drives the material box 4 to swing to the discharge guide sleeve 6. The protrusion 43 limits the box door 41, causing the box door 41 to open and pour the product in the material box 4 into the discharge guide sleeve 6 to achieve unloading. Compared with the traditional robotic arm unloading, it has the advantages of simple structure and simple operation. Compared with the traditional direct ejection unloading, the removal range of the cutter head module 7 is smaller, which can improve work efficiency. At the same time, it can also avoid the product from mixing with iron filings and cutting fluid. In this invention, the box door 41 is hinged to the material box 4, and is also connected to the material box 4 via a tension spring 44. The box door 41 automatically opens by cooperating with the material guide sleeve 6 via a protrusion 43. When the material box 4 separates from the material guide sleeve 6, the box door 41 automatically closes under the restoring force of the tension spring 44. The connecting end of the connecting shaft 2 is provided with a keyway 21, and the upper end of the swing arm 3 has a corresponding limiting key 31 in the connecting hole. The limiting key 31 cooperates with the keyway 21 to achieve circumferential limiting of the swing arm 3 and the connecting shaft 2, ensuring the accuracy of the swing angle.
