Description

Technical Field

[0001] The utility model relates to numerical control machine tool technology, in particular to an automatic feeding mechanism for a numerical control sawing machine. Background Art

[0002] CNC sawing machines use circular saw blades, saw bands or saw blades as cutting tools to saw metal round materials, square materials, pipe materials and profiles. The processing accuracy of CNC sawing machines is generally not very high, and they are mostly used in material preparation workshops to cut various bars, pipes and other profiles. CNC machine tools require a feeding device during processing. The existing feeding device generally drives multiple conveyor rollers driven by a motor to rotate and push the workpiece to move.

[0003] There are many existing technologies for CNC sawing machines, such as:

[0004] Chinese patent publication number CN 220463113 U discloses an automatic feeding device for a CNC sawing machine, which includes a support seat, a moving wheel is fixedly connected to the bottom of the support seat, a driving motor is fixedly connected to one side of the support seat, a connecting shaft is arranged inside the support seat, a belt transmission mechanism is installed on the outer wall of the connecting shaft, a movable shaft is installed on the inner wall of the connecting shaft, a positioning block is fixedly connected to one side of the movable shaft, and a roller mechanism is installed inside the positioning block. The device is provided with a support seat, a moving wheel, a driving motor, a connecting shaft, a belt transmission mechanism, a movable shaft, a reset spring, a connecting block, a positioning block, a roller mechanism, a conveying roller, a support shaft and a mounting block, so as to realize rapid installation of the conveying roller, facilitate material transportation, meet people's work needs, and is worthy of popularization and use.

[0005] It can be seen that the CNC sawing machine uses multiple sets of conveyor shafts to transport the materials placed on it, which makes it convenient for the sawing machine to saw the materials. However, the surface of the conveyor roller is smooth. Although most block materials can be transported and loaded, when feeding rod-shaped materials, the rod-shaped materials will roll on the conveyor roller, which is inconvenient to transport. The rod-shaped materials can only be loaded one by one by clamping, and the loading efficiency is low.

[0006] In view of this, the utility model provides an automatic feeding mechanism for a numerically controlled sawing machine. Utility Model Content

[0007] The utility model aims to provide an automatic feeding mechanism for a numerically controlled sawing machine to solve the problems raised in the above-mentioned background technology.

[0008] To achieve the above object, the utility model provides an automatic feeding mechanism for a CNC sawing machine, comprising a loading platform, a limit group is installed inside the loading platform, and an auxiliary roller is installed inside the limit group.

[0009] The limit group includes a mounting block, a notch is formed at the top of the mounting block, a bidirectional screw is rotatably mounted inside the notch, a connecting rod is threadedly connected to the outer surface of the bidirectional screw, one end of the bidirectional screw passes through the mounting block and the loading platform and a first motor is mounted thereon, and a limit plate is fixedly mounted on the top of the connecting rod.

[0010] The auxiliary roller includes a rolling shaft, connecting shafts are installed at both ends of the rolling shaft, and the outer surface of the roller shaft is provided with anti-slip grooves.

[0011] As a further improvement of the technical solution, the loading platform includes a plurality of conveying rollers, which are rotatably mounted on the inner wall of the loading platform, a second motor is mounted on one end of the conveying rollers, and the plurality of conveying rollers are connected by tracks.

[0012] As a further improvement of the technical solution, the limit plate is arranged on the top of the conveying roller, and the connecting rod is arranged between adjacent conveying rollers.

[0013] As a further improvement of the technical solution, two limit plates are provided on the outer surface of the bidirectional screw rod, and the two limit plates are relatively moved by the rotation of the bidirectional screw rod.

[0014] As a further improvement of the technical solution, a mounting groove is provided on the outer wall of the limit plate, and the rolling shaft is rotatably mounted on the inner wall of the mounting groove through connecting shafts at both ends.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] In the automatic feeding mechanism of the CNC sawing machine, a limiting group is set, and the bidirectional lead screw is driven to rotate by powering on the first motor, and the outer wall of the connecting rod is fitted on the inner wall of the mounting block slot and is threadedly connected to the outer surface of the bidirectional lead screw. The rotation of the bidirectional lead screw drives the limiting plate fixedly installed on the top of the connecting rod to move, and the limiting plate moves on the top of the conveying roller to limit and squeeze the material on the conveying roller to prevent the rod-shaped material from rolling. In addition, the limiting plate can limit multiple rod-shaped materials at one time, so that the feeding efficiency of the rod-shaped material on the conveying roller is more efficient.

[0017] In the automatic feeding mechanism of the CNC sawing machine, after the limiting plate limits and squeezes the material, the material may be squeezed too tightly and cannot move. By setting an auxiliary roller, after the limiting plate limits and squeezes the material, the outer surface of the material will contact the rolling shaft in the mounting groove of the outer wall of the limiting plate. The outer surface of the rolling shaft is provided with anti-slip grooves. When the material is conveyed on the top of the conveying roller, the limiting plate squeezes the material, and the material can also be conveyed forward by the rolling shaft to avoid material jamming, thereby achieving the effect of conveying and feeding the rod-shaped material.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example

[0026] See also Figure 1-Figure 4 As shown, this embodiment provides an automatic feeding mechanism for a CNC sawing machine, including a loading table 1, a limiting group 2 is installed inside the loading table 1, and an auxiliary roller 3 is installed inside the limiting group 2.

[0027] First, the specific structure of the limit group 2 is disclosed. The limit group 2 includes a mounting block 201, and both ends of the mounting block 201 are fixedly mounted on the inner wall of the frame of the loading platform 1. The mounting block 201 is fixedly mounted, and a notch is formed at the top of the mounting block 201. A bidirectional screw rod 202 is rotatably mounted inside the notch. Both ends of the bidirectional screw rod 202 are rotatably mounted in the notch at the top of the mounting block 201, so that one end of the bidirectional screw rod 202 passes through the outside of the mounting block 201 and the frame of the loading platform 1, and can be connected to the output shaft of the first motor 204. The first motor 204 is energized to drive the bidirectional screw rod 202 to rotate, and the outer surface of the bidirectional screw rod 202 is threadedly connected with a connecting rod 203. One end of the bidirectional screw rod 202 passes through the mounting block 201 and the loading platform 1 and is equipped with a first motor 204. A limiting plate 205 is fixedly installed on the top of the connecting rod 203. Then, the outer wall of the connecting rod 203 fits against the inner wall of the groove of the mounting block 201 and is threadedly connected to the outer surface of the bidirectional screw rod 202. The rotation of the bidirectional screw rod 202 drives the limiting plate 205 fixedly installed on the top of the connecting rod 203 to move. The limiting plate 205 moves on the top of the conveying roller 101 to limit and squeeze the material on the conveying roller 101 to prevent the rod-shaped material from rolling. In addition, the limiting plate 205 can limit multiple rod-shaped materials at one time, so that the feeding efficiency of the rod-shaped material on the conveying roller 101 is more efficient.

[0028] Secondly, the specific structure of the auxiliary roller 3 is disclosed. The auxiliary roller 3 includes a rolling shaft 301, and connecting shafts 302 are installed at both ends of the rolling shaft 301. The outer surface of the rolling shaft 301 is provided with anti-slip grooves. The connecting shafts 302 at both ends of the rolling shaft 301 are rotatably installed in the installation groove 4 provided on the outer wall of the limiting plate 205. After the limiting plate 205 limits and squeezes the material, the outer surface of the material will contact the rolling shaft 301 in the installation groove 4 on the outer wall of the limiting plate 205. The outer surface of the rolling shaft 301 is provided with anti-slip grooves to increase the friction between the material and the limiting plate 205 to prevent the material from sliding. When the material is conveyed at the top of the conveying roller 101, the limiting plate 205 squeezes the material, and the material can also be conveyed forward by the rolling shaft 301 to avoid material jamming.

[0029] The improvement of this embodiment is that: a plurality of limit plates 205 are arranged in the middle of the conveying roller 101, and when the rod-shaped material is transported on the conveying roller 101, the first motor 204 drives the bidirectional screw rod 202 to rotate, so that the limit plates 205 limit and squeeze the material on the conveying roller 101, so as to avoid the situation that the rod-shaped material rolls on the conveying roller 101 and cannot be loaded. The limit plates 205 can move on the top of the conveying roller shaft 101 group to limit the plurality of rod-shaped materials on the conveying roller 101, and solve the problems in the prior art that the rod-shaped material cannot be transported when rolling on the conveying roller 101 or the transportation efficiency of multiple rod-shaped materials is low.

[0030] Considering how the limit plate 205 is installed in the loading platform 1, the structure of the loading platform 1 is described. The loading platform 1 includes a plurality of conveying rollers 101, and the plurality of conveying rollers 101 are rotatably installed on the inner wall of the loading platform 1. A second motor 102 is installed at one end of the conveying roller 101. The plurality of conveying rollers 101 are connected by a track. The plurality of conveying rollers 101 are rotatably installed on the inner wall of the loading platform 1. The second motor 102 is energized to drive the conveying rollers 101 to rotate, and other groups of conveying rollers 101 are connected and rotated by the track.

[0031] Furthermore, a limit plate 205 is disposed on the top of the conveying roller 101, and a connecting rod 203 is disposed between adjacent conveying rollers 101. The limit plate 205 is installed on the top of the conveying roller 101, and the limit plate 205 is disposed in the middle of two adjacent conveying rollers 101. The limit plate 205 can be moved on the top of the conveying roller 101 to limit the material on the top of the conveying roller 101.

[0032] Since the rod-shaped material will roll left and right on the conveying roller 101 , two limit plates 205 are provided on the outer surface of the bidirectional screw rod 202 , and the two limit plates 205 are relatively moved by the rotation of the bidirectional screw rod 202 .

[0033] The improvement lies in that the two limiting plates 205 move relatively on the bidirectional screw rod 202 via the two connecting rods 203 to limit the rod-shaped material and prevent the rod-shaped material from rolling.

[0034] Furthermore, the outer wall of the limit plate 205 is provided with a mounting groove 4, and the rolling shaft 301 is rotatably mounted on the inner wall of the mounting groove 4 through the connecting shafts 302 at both ends. The rolling shaft 301 is rotatably mounted in the mounting groove 4 on the outer wall of the limit plate 205 through the connecting shafts 302 at both ends, so that after the limit plate 205 squeezes the rod-shaped material, the material can be moved and transported with the help of the rolling shaft 301, thereby preventing the material from being squeezed and stuck and unable to be transported.

[0035] When the automatic feeding mechanism for the CNC sawing machine in this embodiment is used, the first motor 204 is energized to drive the bidirectional screw rod 202 to rotate, the outer wall of the connecting rod 203 is attached to the inner wall of the notch of the mounting block 201 and is threadedly connected to the outer surface of the bidirectional screw rod 202, and the rotation of the bidirectional screw rod 202 drives the limit plate 205 fixedly installed on the top of the connecting rod 203 to move, and the limit plate 205 moves on the top of the conveying roller 101 to limit and squeeze the material on the conveying roller 101 to prevent the rod-shaped material from rolling, and the limit plate 205 can limit multiple rod-shaped materials at one time. The material is limited, so that the feeding efficiency of the rod-shaped material on the conveying roller 101 is more efficient. After the limiting plate 205 limits and squeezes the material, the outer surface of the material will contact the rolling shaft 301 in the outer wall mounting groove 4 of the limiting plate 205. The outer surface of the rolling shaft 301 is provided with anti-slip grooves to increase the friction between the material and the limiting plate 205 to prevent the material from sliding. When the material is conveyed at the top of the conveying roller 101, the limiting plate 205 squeezes the material, and the material can also be conveyed forward by means of the rolling shaft 301 to avoid material jamming, thereby achieving the effect of conveying and feeding the rod-shaped material.
