Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, specifically to an adjustable bolt guide machine. Background Technology

[0002] Bolts are a common type of fastener, consisting of a head and a shank. Bolt production and assembly involve an orderly feeding process, currently often using vibratory feeders and conveyor tracks. For example, prior art CN220702425U discloses a fastener assembly feeding device, including a vibratory feeder with a screening track at the feed outlet. The screening track includes a first side plate and a second side plate that cooperate with each other, and a drive assembly that drives the first and second side plates to close or separate. The drive assembly includes a first handwheel, a first lead screw, and a second lead screw, with opposite helical directions. This technical solution allows the screening track to adjust the width of the screening groove, thereby adapting to fasteners of different specifications and completing the automatic feeding of different fasteners.

[0003] However, the existing technology has the following technical problems: it lacks lateral and top limiting mechanisms. When the bolt enters the screening track, the screw is located in the screening trough, while the screw head is located on the upper surface of the two side plates. During the vibration conveying process, there are no limiting mechanisms on both sides of the screw head, which can easily cause problems such as swaying, deviation, or tilting. Furthermore, there is no limiting mechanism at the top, which can easily cause bouncing and deviation during vibration conveying. These problems not only affect the stability of the conveying process but can also lead to material jamming and blockage in severe cases, thereby affecting the continuous operation of the production line. Utility Model Content

[0004] This utility model provides an adjustable bolt guide machine, which can solve the technical problem that the existing conveying guide rails lack lateral and top limiting functions, which leads to easy deviation, bouncing, and jamming during vibration conveying, thereby reducing the conveying stability.

[0005] This application provides the following technical solution:

[0006] An adjustable bolt guide machine includes a conveying guide rail connected to the discharge port of a vibratory feeder. The conveying guide rail includes two symmetrically arranged frames, two sets of side plates located inside the frames, and a drive assembly for driving the two sets of side plates to move closer or further apart. Each side plate includes a connecting arm and an inverted L-shaped guide rail. The two sets of guide rails form a T-shaped material trough. The drive assembly includes a drive component and a lead screw with bidirectional positive and negative threads. Two sets of sliders are arranged on the lead screw. The drive component is used to drive the two sets of sliders to move closer or further apart. The connecting arms of the two side plates are respectively fixed to the two sliders. A spring plate is also provided on the inner side of the connecting arm along its length. The spring plate is used to limit the movement of the bolt head on both sides. An elastic top plate is also provided above the material trough. The elastic top plate has a gap with the top of the bolt located in the material trough. When the bolt bounces, it contacts the elastic top plate and returns to the material trough under the reaction force of the elastic top plate.

[0007] Beneficial effects:

[0008] 1. By setting the spring plate on the connecting arm, the spring plate can move with the guide rail to accommodate bolts of different specifications and limit the bolt head on both sides to prevent the bolt from shifting or tilting during vibration conveying. Moreover, due to the elasticity of the spring plate, compared with a fixed limiting block, the spring plate can provide a buffering force when contacting the bolt, reducing wear and noise caused by rigid collision. At the same time, through elastic deformation, it adaptively compensates for small deviations in the bolt position. Even if the bolt generates high-frequency vibration during vibration, the spring plate can maintain a good limiting state, ensuring a stable and efficient conveying process.

[0009] 2. By installing an elastic top plate above the material trough, with a gap between the elastic top plate and the top of the bolt, the bolt's linear movement along the material trough is not affected during normal conveying, avoiding the frictional resistance or jamming that may occur with traditional rigid top plates. When the bolt bounces vertically due to vibration, its top contacts the elastic top plate, and the elastic reaction force of the top plate forces the bolt to quickly fall back into the material trough, avoiding displacement or jamming caused by bouncing or damage caused by rigid collision with the top of the equipment. Moreover, compared with rigid top plates, the elastic reaction force of the elastic top plate has a certain adjustment effect on the bolt, reducing jamming and improving the efficiency and stability of conveying.

[0010] 3. When the lead screw is driven to rotate by the lead screw drive component with bidirectional positive and negative teeth, the sliders on both sides can move synchronously and in opposite directions, so as to realize the precise adjustment of the distance between the guide rails on both sides and can quickly adapt to bolts of different diameters; in addition, the lead screw drive has a self-locking characteristic, which can prevent the side plate from loosening due to vibration during the conveying process and ensure the stability of the limit distance.

[0011] Furthermore, a horizontal plate is provided on the top of the frame, and an elastic top plate is provided on the horizontal plate. The elastic top plate includes a flat plate and an elastic element. One end of the elastic element is connected to the horizontal plate, and the other end is connected to the flat plate.

[0012] Beneficial effects: The horizontal plate is set at the top of the frame, making full use of the vertical space of the equipment. This ensures that the installation of the flexible top plate does not affect the adjustment of the side plates on both sides of the trough and the normal operation of other components, thus guaranteeing the compactness of the overall layout of the equipment.

[0013] Furthermore, the horizontal plate is also provided with a column, and the plate is provided with a through hole. The column is inserted into the through hole and slidably connected to the plate. The elastic element is a spring, which is sleeved on the column.

[0014] Beneficial effects: The column is inserted into the through hole of the plate to form a sliding connection, which provides precise guidance for the up and down movement of the plate; when the bolt bounces and impacts the plate, the plate can only move along the axial direction of the column, avoiding lateral offset or tilting caused by uneven force, ensuring that the elastic top plate always acts vertically on the top of the bolt, and improving the accuracy of the limit.

[0015] Furthermore, support arms are provided on both sides of the horizontal plate, and several vertically arranged adjustment holes are provided on the support arms. The support arms are fixed to the outer wall of the frame by fasteners.

[0016] Beneficial effects: By setting up a support arm and setting adjustment holes on the support arm, it is easy to adjust the height of the horizontal plate, and thus adjust the height of the elastic top plate to adapt to different types or heights of screw heads.

[0017] Furthermore, guide rods are provided on the opposite side of the two sets of frames, and guide channels are provided on the horizontal edge of the guide rail, with the guide rods slidably positioned within the guide channels.

[0018] Beneficial effects: By setting guide rods and guide channels to guide the movement of the guide rails, the two sets of guide rails can move closer to or further away from each other smoothly and accurately.

[0019] Furthermore, the lead screw is also equipped with marking scale lines.

[0020] Beneficial effects: The graduated markings provide a visual reference for adjusting the side plate spacing. Operators can directly read the scale values ​​on the lead screw based on the bolt specifications to control the movement distance of the sliders on both sides, eliminating the need for repeated measurements or adjustments. For example, when replacing bolts of different diameters, the width of the feed trough can be quickly adjusted to the appropriate size by comparing the scale markings, significantly improving the accuracy and efficiency of equipment parameter adjustment.

[0021] Furthermore, the driving component is a motor. Attached Figure Description

[0028] Example

[0029] like Figure 1 As shown, the adjustable bolt guide machine includes a conveying guide rail connected to the discharge port of the vibratory feeder. The front end of the conveying guide rail is provided with an outwardly curved connecting part 11. The connecting part 11 is elastic and is used to abut against the inner side of the discharge port of the vibratory feeder. The conveying guide rail includes two sets of symmetrically arranged frames 1, two sets of side plates 2 arranged inside the frames 1, and a drive assembly for driving the two sets of side plates 2 to move closer or separate.

[0030] like Figure 3 As shown, in this embodiment, the side plate 2 includes an integrally formed connecting arm 21 and an inverted L-shaped guide rail 22. The two sets of guide rails 22 form a T-shaped material groove 20 for the bolt 100 to pass through; specifically as follows... Figure 1 As shown, in this embodiment, one end of the connecting part 11 is welded to the front end of the guide rail 22, and the other end abuts against the inner side of the vibratory feeder outlet, so that the bolt 100 can smoothly enter the material trough 20 of the conveying guide rail from the vibratory feeder outlet.

[0031] The drive assembly includes a drive component 30 and a lead screw 3 with bidirectional positive and negative teeth. Two sets of sliders 31 are provided on the lead screw 3. The drive component 30 is used to drive the two sets of sliders 31 to move closer or further apart. Specifically, the lead screw 3 is rotatably mounted on two sets of frames 1, and one end of the lead screw 3 extends out of the frame 1 for connection with the external drive component 30. In this embodiment, the drive component 30 is a motor.

[0032] Furthermore, in this embodiment, the lead screw 3 is also equipped with a scale line (not shown), providing a direct reference for adjusting the spacing of the side plates 2. The operator can directly read the scale value on the lead screw 3 according to the bolt 100 specification to control the movement distance of the sliders 31 on both sides, without the need for repeated measurements or adjustments. To improve the stability of the guide rail 22 movement, such as... Figure 3 As shown, in this embodiment, a guide rod 12 is also provided on one side opposite to the two sets of frames 1, and a guide channel 221 is provided on the horizontal side of the guide rail 22. The guide rod 12 is slidably disposed in the guide channel 221. Specifically, the guide rod 12 can be fixed by common methods such as bolts 100, which will not be described in detail here.

[0033] like Figure 3 As shown, in this embodiment, the connecting arms 21 of the two side plates 2 are respectively fixed to the two sliders 31 by bolts 100; the inner side of the connecting arm 21 is also provided with a spring plate 211 arranged along its length direction, and the spring plate 211 is used to limit the two sides of the screw head. Figure 2 , 4 An elastic top plate 4 is also provided above the material trough 20. The elastic top plate 4 has a gap with the top of the bolt 100 located in the material trough 20. When the bolt 100 bounces, it contacts the elastic top plate 4 and resets to the material trough 20 under the reaction force of the elastic top plate 4.

[0034] Specific examples Figure 2 As shown, a horizontal plate 5 is provided on the top of the frame 1, and an elastic top plate 4 is provided on the horizontal plate 5. The elastic top plate 4 includes a flat plate 41 and an elastic element. One end of the elastic element is connected to the horizontal plate 5, and the other end is connected to the flat plate 41. Specifically, the flat plate 41 can be made of transparent plastic to facilitate observation of the bolts 100 inside the material trough 20 from above; Figure 4 As shown, in this embodiment, a column 43 is also provided on the horizontal plate 5, and a through hole is provided on the flat plate 41. The column 43 is inserted into the through hole and slidably connected to the flat plate 41. The elastic element is a spring 42, which is sleeved on the column 43.

[0035] In this embodiment, in order to facilitate the adjustment of the height of the elastic top plate 4, support arms 51 are also provided on both sides of the horizontal plate 5. The support arms 51 are provided with several vertically arranged adjustment holes (not shown). The support arms 51 are fixed to the outer wall of the frame 1 by fasteners such as screws passing through the adjustment holes.

[0036] In use, the gap between the material troughs 20 of the two sets of guide rails 22 is adjusted according to the model of the bolt 100. Then, the bolt is fed sequentially by a vibratory feeder. When the bolt 100 enters the material trough 20, the bottom of its screw head abuts against the horizontal edge of the guide rail 22 and continues to be conveyed forward under the action of vibration (vibratory feeding is an existing technology in the field of vibratory feeder conveying, and this embodiment has not improved it, so it will not be described in detail here). During the conveying process, the spring plates 211 on the left and right sides limit the screw head, which can prevent the bolt 100 from swinging, shifting, deflecting or tilting during the transportation process. When the bolt 100 bounces during the conveying process, the top contacts the elastic plate 41, and under the elastic reaction force of the spring 42, the bolt 100 is forced to fall back into the material trough 20 quickly, avoiding the damage caused by the bouncing, such as offset jamming or rigid collision with the top of the equipment.

[0037] In summary, the adjustable guide structure of this application enables the conveying guide rail to be used for conveying different types and models of bolts 100, and also allows for limiting the movement of bolts during conveying, thereby improving the stability and continuity of conveying, reducing problems such as jamming and blockage, and improving conveying efficiency.
