Description

Technical Field

[0001] The utility model relates to an integrated nail assembling machine, in particular to a rotary lifting type integrated nail automatic assembling machine. Background Art

[0002] Integrated nails are nails used in nail guns, generally including nail parts and gaskets. When assembling and processing them, the nail parts and gaskets are combined manually or by a mechanized assembly machine. The Chinese utility model patent with the publication number CN217019331U discloses an integrated nail automatic assembling device, and its assembling sequence is as follows: the nail parts enter the conveying disc through the feeding chute and are clamped. When the nail parts move above the position where the gaskets are located, the cam push rod pushes the gaskets on the gasket feeding chute rack upward to press the gaskets onto the nails, completing the assembly of the integrated nails. The existing mechanized way to replace the manual operation mode can improve the processing efficiency to a certain extent and save labor costs, but there are still some problems. The device pauses during the process of completing the assembly actions of the nail parts and gaskets, which requires the rotation of the conveying disc to be one rotation and one stop to cooperate with the pressing action. Moreover, most of the conveying discs use 8-indexing discs or 12-indexing discs, making it difficult to further increase the rotation speed, resulting in low production efficiency. The upper limit of the number of integrated nails that can be assembled per minute is about 200. At the same time, the one-rotation-and-one-stop rotation mode is likely to cause wear of the machine power mechanism. Content of the Utility Model

Detailed implementation manners

[0025] The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. It should be understood that the rotary lifting integrated nail automatic assembly machine described herein is a preferred embodiment, which is only used to illustrate and explain the present utility model and does not constitute a limitation to the present utility model.

[0026] As Figures 1 to 5 shown, it is a rotary lifting integrated nail automatic assembly machine, including a frame 1, a feeding unit, an assembly unit, and a discharging unit.

[0027] The feeding unit includes a nail body feeding unit and a gasket feeding unit. As Figure 1 shown, the feeding unit is arranged on the frame 1. The nail body feeding unit includes a nail body feeding cylinder 30 and a nail body conveying track 31. One end of the nail body conveying track 31 is connected to the nail body feeding cylinder 30, and the other end extends towards the assembly unit. The gasket feeding unit includes a gasket feeding cylinder 32 and a gasket conveying track 33. One end of the gasket conveying track 33 is connected to the gasket feeding cylinder 32, and the other end extends towards the assembly unit. The nail body feeding unit and the gasket feeding unit can adopt conventional technical means.

[0028] The assembly unit includes a central rotating shaft 4, a lifting plate 10, an upper positioning disc 12, and a positioning round sleeve 18. In this embodiment, the central rotating shaft 4 is vertically arranged and fixed by a support frame fixed on the frame 1. As Figure 1 , Figure 2 shown, the support frame in this embodiment is set as an inverted L shape, including a vertically arranged support column 2 and a horizontally arranged support plate 3. The lower end of the support column 2 is fixedly arranged on the frame 1, and the support plate 3 is rotatably connected to the upper end of the central rotating shaft 4. The lower end of the central rotating shaft 4 passes through the bottom plate of the frame 1 and is rotatably connected to the bottom plate of the frame 1. In this embodiment, the rotational connection is set as a bearing connection, that is, the support plate 3 and the upper end of the central rotating shaft 4 are rotatably connected through a first bearing (not shown in the figure), and the central rotating shaft 4 and the bottom plate of the frame 1 are rotatably connected through a second bearing 5. Of course, the central rotating shaft 4 can also be vertically arranged on the frame 1 in other forms of rotation.

[0029] As Figure 3 , Figure 4 shown, an upper positioning disk 12 is fixedly arranged on the upper part of the central rotating shaft 4, and a positioning circular sleeve 18 is fixedly arranged in the middle of the central rotating shaft 4. The upper positioning disk 12 and the positioning circular sleeve 18 rotate coaxially with the central rotating shaft 4. A lifting plate 10 fixedly arranged on the frame 1 is arranged along the circumferential direction of the central rotating shaft 4. The lifting plate 10 is provided with a rising section and a descending section in the height direction. The circumferential parts provided with the rising section and the descending section are assembly areas, and the circumferential parts not provided with the rising section and the descending section are placement areas. Specifically, in this embodiment, the lifting plate 10 is erected in a semi-circular shape, and a rising section and a descending section are arranged in its height direction. The lifting plate 10 divides the circumference into two parts. The semi-circle provided with the lifting plate 10 is the assembly area, and the semi-circle not provided with the lifting plate 10 is the placement area. Of course, the lifting plate 10 can also be arranged in a complete circular shape. At this time, the lifting plate 10 is provided with a rising section, a descending section and a horizontal section in the height direction. The horizontal section is the lowest in height. The circumferential parts provided with the rising section and the descending section are assembly areas, and the circumferential part provided with the horizontal section is the placement area. The placement area refers to the area for placing the nail body 16 and the gasket 26, and the assembly area refers to the area where the nail body 16 and the gasket 26 are assembled.

[0030] In this embodiment, a limiting plate 11 is further arranged above the descending section of the lifting plate 10. The lower end surface of the limiting plate 11 has the same slope as the descending section of the lifting plate 10 and forms a track space with the upper end surface of the lifting plate 10.

[0031] A number of nail body assembly stations in the vertical direction are fixedly arranged on the outer circumference of the upper positioning disk 12. The nail body assembly stations include nail body positioning plates 14. The nail body positioning plates 14 are fixedly arranged on the outer circumference of the upper positioning disk 12. A magnetic column for magnetically attracting and fixing the nail body 16, specifically a slender magnetic column 15, is fixedly arranged on one side of the nail body positioning plate 14 away from the central rotating shaft 4. When the nail body 16 enters the nail body assembly station, the metal part of the nail body 16 is magnetically attracted and fixed; a pressing disk 13 is further arranged above the nail body positioning plate 14. The pressing disk 13 is fixedly arranged on the central rotating shaft 4. A placement space for the nail body 16 is formed between the pressing disk 13 and the nail body positioning plate 14. When the nail body 16 and the gasket 26 are assembled, the nail body 16 will be subjected to an upward thrust. At this time, the upper pressing disk 13 can prevent the position of the nail body 16 from moving and cooperate to complete the insertion of the gasket 26 into the nail body 16. In this embodiment, 24 nail body assembly stations are evenly distributed along the circumference of the upper positioning disk 12. The position of one of the nail body assembly stations within the range of the placement area is the station for placing the nail body 16, and this station for placing the nail body 16 is connected to one end of the nail body conveying track 31.

[0032] A gasket assembling mechanism that can slide vertically and corresponds to the nail body assembling station is provided on the positioning collar 18. The gasket assembling mechanism can move up and down along the lifting plate 10 while continuously rotating driven by the positioning collar 18. Specifically, the gasket assembling mechanism includes a sliding cylinder 19, which is placed vertically and movably in a positioning hole 20 vertically opened on the positioning collar 18. The positioning hole 20 is arranged corresponding to the position of the nail body 16 at the nail body assembling station; a gasket assembling station is fixedly arranged at the top end of the sliding cylinder 19. The gasket assembling station includes a gasket positioning sleeve 24 fixedly arranged thereon for placing the gasket 26. Among them, the upper surface of the gasket positioning sleeve 24 has a groove with the same size as the gasket 26. A sliding block 21 is fixedly arranged at the lower end of the sliding cylinder 19. One end of the sliding block 21 away from the central rotating shaft 4 is fixedly provided with a roller 22, and the roller 22 is movably placed on the lifting plate 10. The gasket assembling mechanism can move up and down along the lifting plate 10 while continuously rotating driven by the positioning collar 18. When the gasket assembling mechanism moves to the highest point of the assembling area, the gasket assembling station at its top end coincides with the lower end of the nail body 16 at the nail body assembling station, that is, the nail body 16 can be inserted into the central hole of the gasket 26 placed in the gasket positioning sleeve 24 to complete the assembly of the integrated nail. The position of one of the gasket assembling stations within the placement area range is the station for placing the gasket 26. This station for placing the gasket 26 is connected to one end of the gasket conveying track 33, and the gasket 26 can be horizontally placed into the gasket positioning sleeve 24.

[0033] Since the gasket 26 of the integrated nail is a circular sheet body with a hole in the center, in order to accurately position the gasket 26 on the gasket positioning sleeve 24 and prevent it from falling off, a gasket positioning rod 25 is also provided in this embodiment. Specifically, the assembling unit further includes a lower positioning disk 27 fixedly arranged at the lower part of the central rotating shaft 4. The lower positioning disk 27 rotates coaxially and at the same speed as the upper positioning disk 12 and the positioning collar 18. A vertically arranged gasket positioning rod 25 corresponding to the sliding cylinder 19 is fixedly arranged on the lower positioning disk 27, and the upper part of the gasket positioning rod 25 is placed inside the sliding cylinder 19. The top end of the gasket positioning rod 25 can extend out of the gasket assembling station and pass through the central hole of the gasket 26 when the sliding cylinder 19 rotates to the placement area to fix the gasket. When the sliding cylinder 19 drives the gasket assembling station to enter the rising slope section of the assembling area, the top end of the gasket positioning rod 25 leaves the central hole of the gasket 26 so that the tip of the nail body 16 can be inserted into the central hole of the gasket 26.

[0034] In order to enable the gasket assembly mechanism to move up and down stably in the vertical direction and limit its upper and lower limit positions of movement, a limiting vertical hole 23 for controlling the up and down movement range of the sliding block 21 is further provided in this embodiment. Specifically, the positioning round sleeve 18 is fixedly arranged on the central rotating shaft 4 through the sleeve 17. A limiting vertical hole 23 corresponding to the sliding cylinder 19 is opened on the sleeve 17. A convex block is fixedly arranged at one end of the sliding block 21 close to the central rotating shaft 4, and the convex block is placed in the limiting vertical hole 23. The lower end of the limiting vertical hole 23 is flush with the lowest position of the lifting plate 10. When the lower end of the convex block is located at the lowest position of the limiting vertical hole, the roller 22 can slide into the ascending section of the lifting plate 10 without obstruction. The upper end of the limiting hole 23 can control the highest position of the movement of the sliding cylinder 19, that is, the position where the lower end of the nail body 16 is inserted into the central hole of the gasket 26 placed in the gasket positioning sleeve 24.

[0035] The unloading unit includes a blanking dialing member 28 and a blanking chute 29. The blanking dialing member 28 is arranged behind the assembly area. The blanking dialing member 28 is flush with the nail body assembly station in the horizontal position. One end of the blanking dialing member 28 is a tip and is tangent to the circumference where the nail body assembly station is located. When the assembled integrated nail rotates to the tip of the blanking dialing member 28, it is dialed away from the nail body assembly station, and the integrated nail then falls into the blanking chute 29 arranged below the blanking dialing member 28. A box for receiving the integrated nail (not shown in the figure) is placed below the blanking chute 29. A counter (not shown in the figure) can also be arranged in front of the blanking dialing member 28. The counter is connected to a sensor for recording the number of assembled integrated nails. The counter and the sensor can adopt conventional technical means.

[0036] This embodiment further includes a power driving mechanism. The lower end of the central rotating shaft 4 is connected to a power driving mechanism fixedly arranged below the bottom plate of the frame 1. The motor 6, coupling 7, speed reducer 8, synchronous belt 9, etc. are used to drive the central rotating shaft 4 to rotate through power transmission. The assembly speed of the integrated nail can be adjusted by adjusting the rotation speed of the central rotating shaft 4, and it is set in cooperation with the number of nail body assembly stations to achieve efficient assembly.

[0037] When using this embodiment, start the equipment that controls the rotation of the central shaft 4 and the equipment that controls the feeding unit. The central shaft 4 drives the assembly unit to rotate counterclockwise. The gasket feeding unit and the nail body feeding unit are arranged in sequence along the rotation direction and are respectively connected to the station for placing the gasket 26 and the station for placing the nail body 16 in the placement area. Taking the assembly process of one group of integrated nail assembly stations as an example: the gasket feeding unit horizontally places the gasket 26 into the gasket positioning sleeve 24 of one of the gasket assembly stations within the placement area through the gasket conveying track, and is accurately positioned by the gasket positioning rod 25. The gasket assembly station with the gasket 26 placed and the corresponding nail body assembly station continue to rotate together and reach the position for placing the nail body 16 connected to the nail body conveying track 31, which is also within the placement area. The nail body is magnetically fixed on the nail body positioning plate by the slender magnetic column. Subsequently, the gasket assembly station with the gasket 26 and the nail body assembly station with the nail body 16 rotate into the assembly area, and the roller 22 also rolls into the ascending section of the lifting plate 10, that is, drives the gasket assembly station on the sliding cylinder 19 to rise. When the roller 22 moves to the highest point of the lifting plate 10, the gasket 26 placed in the gasket positioning sleeve 24 coincides with the lower end of the nail body 16, so that the nail body 16 is inserted into the central hole of the gasket 26 to complete the assembly of the integrated nail. Then, the roller 22 enters the descending section of the lifting plate 10, driving the gasket assembly station away from the nail body assembly station. With continuous rotation, the assembled integrated nail enters the placement area on the nail body assembly station, and the blanking dial 28 in the blanking unit set in the placement area unloads the integrated nail, and the integrated nail falls into the blanking groove 29. With continuous rotation, a new gasket 26 is placed on this gasket assembly station, and then a new nail body 16 is placed on this nail body assembly station, and the same assembly process continues to be completed. The gaskets and nail bodies are continuously placed during the continuous rotation of the assembly unit, and the rotation of the central shaft 4 is continuous without pause. Therefore, the assembly of the integrated nail is also continuous without interruption. The rotation speed of the central shaft 4 can be adjusted, and the rotation speed can be set in coordination with the number of nail body assembly stations so that the assembly speed reaches 400 - 500 pieces per minute.
