Description

Technical Field

[0001] This application relates to the field of fastener processing technology, and in particular to a fastener chamfering equipment loading mechanism. Background Technology

[0002] Fasteners are a general term for mechanical parts used to fasten two or more parts or components together into a single unit. After fastener processing, sharp corners and burrs are formed on the fastener. Touching these areas with bare hands may cut the skin, and sharp corners may also cause scratches when the parts come into contact with each other. Therefore, chamfering is usually required to remove sharp corners and burrs.

[0003] Existing fastener chamfering equipment requires fasteners to be placed one by one on a conveyor mechanism and then conveyed over a certain distance to the loading port. This results in a long loading time. Furthermore, fasteners with heads, such as bolts and screws, may shift during long-distance conveying, causing errors in the subsequent chamfering process. Utility Model Content

[0004] To address the issues of low loading efficiency and low precision in fastener chamfering equipment, this application provides a fastener chamfering equipment loading mechanism.

[0005] The fastener chamfering equipment loading mechanism provided in this application adopts the following technical solution:

[0006] A fastener chamfering equipment loading mechanism includes:

[0007] Base;

[0008] Support plate, the support plate is fixed on the base, two support plates are spaced apart and parallel to each other, and a number of limiting grooves are spaced apart on the support plate. The limiting grooves on the two support plates are aligned one by one, and a pair of mutually aligned limiting grooves form a fixed station for fasteners to be placed.

[0009] A conveyor plate is located in the gap between two support plates. The conveyor plate is provided with positioning grooves, which are aligned with the fixed workstations one by one. The conveyor plate is connected to a drive mechanism, which includes a lifting mechanism and a linear module. The linear module is fixed on the base, and the lifting mechanism is fixed to the moving end of the linear module. The lifting mechanism drives the conveyor plate to rise, so that the fastener is lifted from the fixed workstation and falls into the positioning groove. The moving end of the linear module drives the conveyor plate to slide, so that the fastener located in the positioning groove moves to above the next fixed workstation. Then, the lifting mechanism drives the conveyor plate to fall down, so that the fastener falls into the fixed workstation.

[0010] By adopting the above technical solution, fasteners are pre-placed on fixed stations. A lifting mechanism drives a conveyor plate upwards, lifting the fasteners from the fixed stations until they fall into positioning slots. Then, a linear module slides, moving the fasteners to the next fixed station. The lifting mechanism then drives the conveyor plate downwards, causing the fasteners in the positioning slots to fall to the next fixed station. Typically, a robotic arm is located on the support plate above the last fixed station near the chamfering station. The robotic arm grips the fasteners and moves them to the subsequent chamfering station. Each rise and fall of the conveyor plate moves one fastener to the next fixed station, ensuring that the last fixed station always has a fastener available for gripping. The linear module slides only one fixed station's distance each time, and the fastener position does not need to be readjusted during the feeding process; the robotic arm can directly grip the fasteners from the fixed stations. Therefore, the fastener feeding time is short, and the fasteners remain relatively stable during feeding, making shaking and rolling difficult, resulting in high feeding efficiency and high precision.

[0011] Preferably, it further includes a limiting plate arranged parallel to the support plate, the limiting plate being fixed on the base, the limiting plate being located on one side of the fixed station, and a gap between the limiting plate and the support plate, so that the head of the fastener is restricted in the gap between the limiting plate and the support plate.

[0012] Preferably, a top plate is provided in the gap between the limiting plate and the support plate. The top plate is arranged parallel to the support plate and is fixed on the lifting mechanism to lift and lower synchronously with the conveying plate, so that the top plate supports the head of the fastener when the fastener is in the positioning groove.

[0013] Preferably, the top of the limiting plate is higher than the height of the top plate when the top plate is raised, so as to prevent the head of the fastener from coming off the top plate when the top plate is raised.

[0014] Preferably, the limiting plate is L-shaped and includes an integrally connected horizontal plate and a vertical plate. The horizontal plate has an oblong connecting hole through which a fastening bolt passes. The horizontal plate is fixedly connected to the base by the fastening bolt. The fastening bolt slides along the connecting hole and is then fixed to adjust the gap between the vertical plate and the support plate.

[0015] Preferably, a first lead screw module for adjusting the position of the linear module is fixed on the linear module, and the slider of the first lead screw module is fixed to the fixed end of the linear module so that the linear module can be adjusted along the sliding direction of the moving end of the linear module.

[0016] Preferably, a second lead screw module is fixed on the base, and the slider of the second lead screw module is fixedly connected to the first lead screw module. The second lead screw module is used to enable the linear module to be raised and lowered for adjustment.

[0017] Preferably, a linear guide rail is connected to the lower part of the second lead screw module. The linear guide rail is fixed on the base and is horizontally arranged along the sliding direction perpendicular to the linear module, so that the linear module can be adjusted along the sliding direction perpendicular to the linear module.

[0018] Preferably, the lifting mechanism includes a lifting plate, which is fixed to the piston end of the lifting mechanism. An adjusting stud is fixed below the top plate, and the end of the adjusting stud away from the top plate passes through the lifting plate. Adjusting nuts are provided on both sides of the adjusting stud, and the height of the top plate is adjusted by adjusting the adjusting nuts.

[0019] Preferably, a fixing plate extends from one side of the lifting plate for the adjusting stud to pass through, and the adjusting nut abuts against both sides of the fixing plate to fix the top plate to the lifting plate.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] The feeding process is simple and efficient. The fasteners are placed one by one into the fixed position at one end of the support plate. There is basically no need to manually adjust the position. Each rise and fall of the conveyor plate moves a fastener to the next fixed position. The linear module slides only one fixed position distance each time. The feeding process does not require readjustment of the fastener position, and the feeding time is short.

[0022] The feeding process is stable and precise. During the feeding process, the fasteners are only subjected to lifting and falling movements, making it difficult for them to shake or roll. Furthermore, the limiting plate and top plate restrict the head of the fasteners, making the movement of the fasteners more stable.

[0023] It has good adaptability and can be adjusted in multiple positions. The limit plate, linear module and top plate can all be adjusted, and it can be adapted to fasteners of different specifications, making it more widely used. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0031] This application discloses a fastener chamfering equipment loading mechanism. (Refer to...) Figure 1 and Figure 2 The fastener chamfering equipment loading mechanism includes a base 1, a support plate 2, a conveyor plate 3, and a drive mechanism 4. The base 1 is used to fix the support plate 2 and the drive mechanism 4. The support plate 2 has fixed stations 21 for placing fasteners. Two support plates 2 are arranged parallel to each other, spaced apart. Fasteners are placed across the two support plates 2 within the fixed stations 21. The conveyor plate 3 is used to transport the fasteners, and the drive mechanism 4 is used to drive the conveyor plate 3 to move. The conveyor plate 3 is located in the gap between the two support plates 2. The drive mechanism 4 drives the conveyor plate 3 to rise, pushing the fasteners off the fixed stations 21 and onto the conveyor plate 3. Then, the drive mechanism 4 drives the conveyor plate 3 to slide, moving the fasteners above the next fixed station 21. Finally, the drive mechanism 4 drives the conveyor plate 3 to descend, causing the fasteners to fall onto the lower fixed station 21, thus moving one fastener one fixed station 21 distance. Typically, a robotic arm is located above the last fixed station 21 near the chamfering station on the support plate 2. The robotic arm is used to clamp the fasteners to the subsequent chamfering station. The aforementioned feeding mechanism enables the fasteners to be replenished in a timely manner after the fasteners on the last fixed station 21 are removed by the robotic arm.

[0032] The support plate 2 has several limiting grooves 22, with adjacent limiting grooves 22 spaced apart. The limiting grooves 22 on two support plates 2 are aligned one-to-one, and a pair of aligned limiting grooves 22 forms a fixed station 21, allowing the fastener to be placed across the two support plates 2 on the fixed station 21, with both ends of the fastener respectively embedded in the two limiting grooves 22. The conveyor plate 3 has positioning grooves 31, which are aligned one-to-one with the fixed station 21. The top of the conveyor plate 3 is lower than the top of the support plate 2, so that the positioning grooves 31 are located below the limiting grooves 22. After the fastener is lifted from the fixed station 21 by the conveyor plate 3, it can fall directly into the positioning grooves 31. To ensure that the fastener remains relatively stable after falling into the positioning grooves 31, it is preferable that there are two conveyor plates 3 arranged in parallel, and correspondingly, the positioning grooves 31 are respectively arranged on the two conveyor plates 3, with each pair of positioning grooves 31 aligned with each pair of limiting grooves 22. In a preferred embodiment, the conveyor plate 3 is a U-shaped plate, the bottom plate of the conveyor plate 3 is used for fixed connection of the drive mechanism 4, and the positioning groove 31 is provided at the top of the two side plates of the conveyor plate 3.

[0033] Reference Figure 3 The drive mechanism 4 includes a lifting mechanism 41 and a linear module 42. The linear module 42 is fixed on the base 1, and the support plate 2 is arranged parallel to the sliding direction of the linear module 42, which is the feeding direction. The lifting mechanism 41 is fixed to the moving end of the linear module 42, and the conveyor plate 3 is fixed on the lifting mechanism 41. The lifting mechanism 41 is used to drive the conveyor plate 3 to rise and fall, so that the fastener is released from the fixed station 21, slides through the linear module 42 to the next fixed station 21, and then falls back into the limiting groove 22.

[0034] Reference Figure 2 The fastener chamfering equipment loading mechanism also includes a limiting plate 5, which is fixed on the base 1 and is arranged parallel to the support plate 2. The limiting plate 5 is located on one side of the support plate 2 and spaced apart from it. When the fastener is in the fixed station 21, the head of the fastener is engaged in the gap between the limiting plate 5 and the support plate 2 to restrict the fastener from moving within the limiting groove 22.

[0035] Reference Figure 2 and Figure 4 A top plate 6, parallel to the support plate 2, is provided in the gap between the limiting plate 5 and the support plate 2. The top plate 6 is fixed to the lifting mechanism 41 and rises and falls synchronously with the conveyor plate 3. When the conveyor plate 3 rises and the fastener falls into the positioning groove 31, the top plate 6 supports the head of the fastener to prevent it from wobbling towards the head. Furthermore, the top of the limiting plate 5 is higher than the height of the top plate 6 when it is raised. When the fastener is supported by the conveyor plate 3 and the top plate 6, the limiting plate 5 can restrict the movement of the fastener, making the fastener relatively stable during the conveying process.

[0036] In a preferred embodiment, the limiting plate 5 is L-shaped and includes an integrally connected horizontal plate 51 and vertical plate 52. The horizontal plate 51 is used to connect with the base 1, and the vertical plate 52 is used to restrict the movement of the fastener. Specifically, the horizontal plate 51 has a waist-shaped connecting hole 511 through which a fastening bolt 512 passes. The horizontal plate 51 is fixedly connected to the base 1 by the fastening bolt 512. The opening direction of the waist-shaped hole is the same as the length direction of the fastener when it is located at the fixed position 21, so that the fastening bolt 512 can be fixed after sliding in the connecting hole 511. This allows adjustment of the gap between the vertical plate 52 and the support plate 2, thereby accommodating fasteners of different sizes.

[0037] Reference Figure 1 A first lead screw module 7 for adjusting the position of the linear module 42 is fixed on the linear module 42. The slider of the first lead screw module 7 is fixed to the fixed end of the linear module 42. By adjusting the first lead screw module 7, the slider moves, thereby adjusting the position of the linear module 42. The lead screw of the first lead screw module 7 is set in a direction parallel to the sliding direction of the linear module 42, so that the linear module 42 can be adjusted in the sliding direction. Further, a second lead screw module 8 is fixed on the base 1. The slider of the second lead screw module 8 is fixedly connected to the first lead screw module 7. The lead screw of the second lead screw module 8 is set vertically. By adjusting the second lead screw module 8, the first lead screw module 7 and the linear module 42 can be raised and lowered, thereby allowing the linear module 42 to be adjusted in height. In addition, a linear guide rail 9 is connected to the second lead screw module 8. The linear guide rail 9 is fixed on the base of the base 1. The linear guide rail 9 is horizontally arranged along the sliding direction perpendicular to the linear module 42. The second lead screw module 8 can move horizontally on the linear guide rail 9 along the sliding direction perpendicular to the linear module 42, thereby enabling the linear module 42 to be adjusted laterally.

[0038] Reference Figure 3 and Figure 4 The lifting mechanism 41 includes a lifting plate 411 and a drive source 412. The drive source 412 is preferably a cylinder. The lifting plate 411 is fixed to the piston end of the cylinder. The conveyor plate 3 is fixed on the lifting plate 411. The drive source 412 is fixed to the moving end of the linear module 42 so that the lifting mechanism 41 slides synchronously when the linear module 42 slides.

[0039] Reference Figure 5An adjusting stud 61 is fixed below the top plate 6. One end of the adjusting stud 61 is fixed below the top plate 6, and the other end of the adjusting stud 61 passes through a lifting plate 411. Adjusting nuts 62 are inserted on both sides of the adjusting stud 61 and the lifting plate 411, respectively. The adjusting nuts 62 securely connect the top plate 6 and the lifting plate 411. The height of the top plate 6 can be adjusted by adjusting the two adjusting nuts 62. As a preferred embodiment, a fixing plate 413 extends from one side of the lifting plate 411 for the adjusting stud 61 to pass through. The fixing plate 413 is fixedly connected to the lifting plate 411, and the adjusting nuts 62 abut against both sides of the fixing plate 413 to securely connect the top plate 6 and the lifting plate 411. The fixing plate 413 is provided so that the adjusting nuts 62 are located outside the lifting plate 411 for easy adjustment.

[0040] The implementation principle of the fastener chamfering equipment loading mechanism in this application embodiment is as follows: After the fastener is placed in the fixed station 21, the head of the fastener is embedded between the limiting plate 5 and the support plate 2, and the rod of the fastener is inserted into the limiting groove 22. The lifting mechanism 41 drives the lifting plate 411 to rise, causing the conveyor plate 3 to rise, pushing the fastener located on the fixed station 21 out to fall into the positioning groove 31. At this time, the top plate 6 supports the head of the fastener to limit the swaying of the fastener. The linear module 42 slides, causing the lifting mechanism 41 and the conveyor plate 3 to slide synchronously, so that the fastener slides to the top of the next fixed station 21, and then drives the lifting plate 411 to fall, so that the fastener located in the positioning groove 31 falls into the fixed station 21 below. The linear module 42 slides the distance of one fixed station 21 each time, and the conveyor plate 3 rises and falls each time, so that one fastener moves to the next fixed station 21. The loading distance is short and the time required is small. The last fixed station 21 always has fasteners that can be clamped, without waiting for loading.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
