Description

Technical Field

[0001] This utility model relates to a height adjustment structure for the nail inlet. Background Technology

[0002] Clamping rivets, a common type of fastener, are widely used in furniture manufacturing, wood assembly, decoration, and packaging industries. Clamping rivets typically have a U-shaped structure with two parallel legs spaced at a fixed interval. During use, they enter the feed channel through the nail gun's feed port and are then driven into the workpiece by a firing mechanism. Because clamping rivets need to maintain parallel legs and enter the channel simultaneously, high precision is required in the height and position of the feed port.

[0003] Current nail guns typically have a fixed-height nail inlet at the front of the gun body to accommodate a specific size of clip nail. When changing to clip nails of different heights or models, if the nail inlet is too high, the clip nail is prone to posture deviation during entry into the channel, and the two legs cannot maintain parallel force, ultimately causing the clip nail to jam or deviate, affecting the nailing effect.

[0004] If the nail inlet is too low, some large-sized clip nails will not be able to enter the channel smoothly, thus limiting the applicability of the nail gun. Utility Model Content

[0005] The purpose of this invention is to provide a simple, flexible, and effective nail insertion height adjustment structure that can prevent nail deviation and jamming.

[0006] The purpose of this utility model is achieved as follows. A height adjustment structure for a nail inlet includes a gun body, a nail guide device, and a positioning bolt. The gun body has a nail inlet channel, and a first bolt hole is located above the nail inlet channel. The nail guide device includes a nail receiving seat and a cover plate. The nail receiving seat has a nail sliding groove with an open top. The front end of the nail receiving seat is inserted into the nail inlet channel, and the nail sliding groove and the nail inlet channel are connected. The head of the cover plate is provided with a positioning plate, the positioning plate includes a vertical section, and the vertical section has a vertical sliding hole with a length greater than the diameter of the positioning bolt; The cover plate is placed in the open opening of the nail sliding groove, and the tail of the cover plate is connected to the gun body. The positioning bolt passes through the vertical sliding hole and locks the first bolt hole, so that the cover plate is located at the top open opening of the nail sliding groove. The head of the cover plate and the front end of the nail receiving seat or the inner bottom wall of the nail inlet channel form a nail inlet.

[0007] By setting vertical sliding holes on the vertical section and using positioning bolts to cooperate with the gun body, the cover plate can be adjusted in height in the vertical direction, thereby driving the cover plate to move accordingly, and thus changing the height of the nail inlet formed between the head of the cover plate and the front end of the nail receiving seat or the bottom wall of the nail inlet channel.

[0008] This structure is simple to adjust and easy to operate. It can be adapted to different specifications of clip nails or nail guns without changing parts, effectively avoiding the phenomenon of nails shifting or getting stuck when entering the nail gun due to the nail inlet being too high, thus improving the compatibility and stability of the nail gun.

[0009] The objective of this utility model can also be achieved by the following technical measures: Furthermore, the positioning plate also includes a transverse section, the transverse section of the cover plate is inserted into the nail infeed channel, and the transverse section and the front end of the nail gun holder or the inner bottom wall of the nail infeed channel form a nail infeed opening.

[0010] By setting vertical sliding holes on the vertical section and using positioning bolts to cooperate with the gun body, the cover plate can be adjusted in height in the vertical direction, thereby driving the horizontal section to move accordingly, and thus changing the height of the nail inlet formed between the horizontal section and the front end of the nail receiving seat or the bottom wall of the nail inlet channel.

[0011] Furthermore, the front end of the cover plate is provided with the positioning plate, which is an L-shaped plate, and the rear end of the cover plate is connected to the gun body.

[0012] Furthermore, it also includes connecting bolts, a connecting lug at the tail end of the cover plate, a through hole in the connecting lug, a second bolt hole in the gun body, and the connecting bolt passing through the through hole to lock the second bolt hole.

[0013] By setting a connecting lug at the tail end of the cover plate and connecting it to the second bolt hole of the gun body using a connecting bolt, a structure with the connecting bolt as the rotation center is formed, allowing the cover plate to rotate during adjustment. This simplifies the adjustment method of the cover plate height, makes operation convenient, and avoids the problem of overall structural loosening.

[0014] Furthermore, the cover plate is an elastic cover plate.

[0015] When the cover plate is an elastic cover plate, its tail end can be fixed to the gun body. The height can be adjusted by relying on the elasticity of the cover plate itself. No additional sliding or rotating mechanism is required, the structure is simplified, the number of parts is reduced, the adjustment is quick and flexible, and the durability and service life can be effectively improved.

[0016] Furthermore, the guide pin device also includes a push pin assembly and a coil spring. The push pin assembly includes a push pin seat, a limiting seat, and a locking bolt. The top of the push pin seat is provided with a connecting part. The length of the connecting part is less than the length of the push pin seat. The portion of the connecting part that extends beyond the length of the push pin seat forms the push pin part. The limiting seat sits on the connecting part, and the locking bolt passes through the limiting seat to lock the connecting part, thereby connecting the push pin seat and the limiting seat. The width of the cover plate is smaller than the width of the nail sliding groove. The cover plate partially blocks the nail sliding groove. The nail pusher assembly is slidably mounted on the nail sliding groove. A rear blocking part is provided at the tail end of the nail sliding groove. The vertical section of the positioning plate constitutes a front blocking part. The front blocking part and the rear blocking part together limit the sliding distance of the nail pusher assembly. One end of the coil spring is connected to the pusher assembly, and the other end of the coil spring is connected to the gun body. The coil spring constitutes the power mechanism of the pusher assembly.

[0017] By setting up a nail pusher assembly and a coil spring, the coil spring provides thrust to the nail pusher assembly, ensuring smooth nail delivery. The cooperation of the limit seat with the front and rear blocking parts can effectively limit the sliding range of the nail pusher assembly. When the limit seat collides with the front blocking part, it can achieve the limit, preventing the nail pusher assembly from moving beyond the limited range. This prevents the firing mechanism from interfering with or colliding with the nail pusher assembly during operation, avoiding damage to parts and improving the reliability and service life of the whole machine.

[0018] Furthermore, it also includes a cylinder, a transmission device, and a firing component. The gun body has a firing channel that is connected to the nail feed channel. The cylinder and the transmission device are placed inside the gun body. The firing component is placed inside the firing component channel. The input end of the cylinder is connected to an external pressurized air source. The output end of the cylinder is connected to the input end of the transmission device. The output end of the transmission device is connected to the firing component. The cylinder drives the firing component to slide along the firing component through the transmission device.

[0019] By incorporating a cylinder, transmission device, and firing component, the cylinder is driven by an external air source. The cylinder then drives the firing component to slide along the channel via the transmission device, thereby achieving efficient firing of the nail. This power structure has a fast response and stable output, ensuring that the nail can accurately and reliably enter the workpiece, thus improving nail firing efficiency and work quality.

[0020] The beneficial effects of this utility model are as follows: This invention features a vertical sliding hole on the vertical section of the positioning plate of the cover plate. By using a positioning bolt to cooperate with the gun body, the cover plate can be adjusted in height in the vertical direction, thereby causing the horizontal section to move accordingly. This changes the height of the nail inlet formed between the horizontal section and the front end of the nail holder or the bottom wall of the nail inlet channel. This structure is simple to adjust and easy to operate. It can be adapted to different specifications of clip nails or nails without replacing parts. It effectively avoids the phenomenon of nails shifting or getting stuck when entering the nail gun due to the nail inlet being too high, thus improving the compatibility and stability of the nail gun.

[0021] In this invention, when the cover plate is an elastic cover plate, its tail end can be fixed to the gun body. The height can be adjusted by relying on the elasticity of the cover plate itself, without the need for additional sliding or rotating mechanisms. The structure is more simplified, the number of parts is reduced, the adjustment is quick and flexible, and the durability and service life can be effectively improved. Attached Figure Description

The top of the push pin seat 71 is provided with a connecting part 74. The length of the connecting part 74 is less than the length of the push pin seat 71. The portion of the connecting part 74 that extends beyond the length of the push pin seat 71 forms a push pin part 75. The limiting seat 72 sits on the connecting part 74, and the locking bolt 73 passes through the limiting seat 72 to lock the connecting part 74, thereby connecting the push pin seat 71 and the limiting seat 72. The width of the cover plate 5 is smaller than the width of the nail sliding groove 41. The cover plate 5 covers part of the nail sliding groove 41. The nail pusher assembly 7 is slidably disposed on the nail sliding groove 41. A rear blocking part 42 is provided at the tail end of the nail sliding groove 41. The vertical section 62 of the positioning plate 6 constitutes a front blocking part. The front blocking part and the rear blocking part 42 together limit the sliding distance of the nail pusher assembly 7. One end of the coil spring 30 is connected to the push nail assembly 7, and the other end of the coil spring 30 is connected to the gun body 1. The coil spring 30 constitutes the power mechanism of the push nail assembly 7.

[0045] Furthermore, the push pin assembly 7 also includes a horizontal extension plate 76 and a vertical extension plate 77. One end of the horizontal extension plate 76 is connected to the limiting seat 72, and the other end of the horizontal extension plate 76 is connected to the vertical extension plate 77. A coil spring seat is provided on one side of the vertical extension plate 77, and the coil spring 30 is sleeved on the coil spring seat. A handle 772 is provided on the other side of the vertical extension plate 77, and a tail plate 761 is provided at the rear end of the horizontal extension plate 76.

[0046] Furthermore, the nail receiving seat 4 is provided with an outward flange 8 on the outside of the nail sliding groove 41, the nail pusher seat 71 is slidably disposed in the nail sliding groove 41, the transverse extension plate 76 and the tail plate 761 sit on the outward flange 8, and the coil spring seat is located below the outward flange 8.

[0047] Furthermore, the limiting seat 72, the lateral extension plate 76, the vertical extension plate 77, and the tail plate 761 are integrally formed.

[0048] Furthermore, the push pin seat 71 is an aluminum push pin seat, and the limiting seat 72 is a limiting seat 72 made of hard metal material.

[0049] Furthermore, it also includes a cylinder 9, a transmission device 10, and a firing component 20. The gun body 1 has a firing channel 15, which is connected to the nail insertion channel 11. The cylinder 9 and the transmission device 10 are placed inside the gun body 1. The firing component 20 is placed inside the firing component channel 15. The input end of the cylinder 9 is connected to an external pressurized air source, and the output end of the cylinder 9 is connected to the input end of the transmission device 10. The output end of the transmission device 10 is connected to the firing component 20. The cylinder 9 drives the firing component 20 to slide along the firing component 20 through the transmission device 10.

[0050] Working principle of the clamping gun: The clamping gun provides pressure to the cylinder 9 via an external air source. The output of the cylinder 9 drives the transmission device 10 to operate. The transmission device 10 further pushes the firing component 20 to slide linearly along the firing channel 15, thereby quickly driving the clamping nail located at the front end of the nail infeed channel 11 into the workpiece. The clamping nail is pushed to the nail infeed port 13 by the nail pusher assembly 7 and the coil spring 30, ensuring that it always maintains its front-end positioning state, and then accurately enters the channel under the action of the firing component 20 to complete the nail shooting operation.

[0051] Method for adjusting the height of the nail inlet 13: By loosening the positioning bolt 3, the vertical sliding hole 621 on the vertical section 62 of the cover plate 5 moves up and down along the positioning bolt 3, causing the overall height of the cover plate 5 to change. The horizontal section 61 of the cover plate 5 rises and falls synchronously, thereby changing the height of the nail inlet 13 between the horizontal section 61 and the front end of the nail holder 4 or the bottom wall of the nail inlet channel 11. After adjusting to the position that matches the specifications of the clip nail 40 used, tighten the positioning bolt 3 to achieve quick and reliable adjustment of the nail inlet 13 height.

[0052] Methods to extend the lifespan of a clamping machine: By adding a tail plate 761 to the pusher assembly 7 and abutting against the outer flange 8 of the nail receiver 4, the pusher assembly 7 is effectively prevented from swinging when it slides to the front end, thereby preventing the pusher part 75 from deviating and being hit by the firing mechanism. The push pin seat 71 is made of lightweight aluminum to reduce the load, and the limit seat 72 is made of high-strength metal to improve wear resistance, ensuring that the parts are not easily damaged under high-frequency use; With the adjustable height of the nail inlet 13, the nail jamming caused by nail offset is reduced, which improves the overall structural stability and durability of the nail clamping gun, thereby significantly extending its service life.
