It is a prior art. A laser head 2 is provided on one side of the electric rod 3. A control panel 4 is fixedly connected to the left side of the upper end of the workbench 1. The operation of the entire device is controlled by the control panel 4. An automatic loading and unloading mechanism is provided on the upper end of the workbench 1. The automatic loading and unloading mechanism is used to load and unload gears.

[0042] The automatic loading and unloading mechanism includes a vertical plate 5 fixedly connected to the front and rear positions of the left upper end of the workbench 1. The vertical plate 5 is used for supporting. The interior of the vertical plate 5 is slidably connected to the first rod 14, and the first rod 14 can move forward and backward relative to the vertical plate 5. The opposite sides of the two first rods 14 are fixedly connected to the V-shaped plate 7, and the V-shaped plate 7 is able to move forward and backward through the first rod 14. The rod wall of the first rod 14 is provided with a first spring 13, and the two V-shaped plates 7 are forced to approach each other through the first spring 13. The lower ends of the V-shaped plates 7 are fixedly connected to support blocks 50. The front and rear positions of the left upper end of the workbench 1 are provided with moving grooves 39. The support blocks 50 can move forward and backward inside the moving grooves 39 and support the V-shaped plates 7. At the same time, the setting of the support blocks 50 is to ensure that there is enough space for the gear to move to the right at the lower end of the V-shaped plate 7. The support blocks 50 are located at the moving The inner sliding of the slot 39, the left side of the workbench 1 is fixedly connected to the first motor 24, the first motor 24 is the existing technology of the driving device, the output end of the first motor 24 is fixedly connected to the reciprocating screw rod 43, the first motor 24 drives the reciprocating screw rod 43 to rotate, the rod wall of the reciprocating screw rod 43 is meshed and connected with the movable plate 25, the reciprocating screw rod 43 rotates to make the meshed movable plate 25 move back and forth left and right, the upper end and front and rear positions of the workbench 1 are fixedly connected to the support plate 11, the two sides of the support plate 11 are fixedly connected to the second rod member 36, the second rod member 36 has a supporting effect on the guide plate 12, the rod wall of the second rod member 36 is provided with a second spring 37, and the two guide plates 12 are forced to move closer to each other by the second spring 37, one side of the second rod member 36 is fixedly connected to the guide plate 12, the two sides of the guide plate 12 are inclined, and the inner wall of the guide plate 12 is provided with an arc groove 35;

[0043] When working, the gear to be marked is placed between the two V-shaped plates 7, and under the action of the first spring 13, the front and rear V-shaped plates 7 limit the gear, and the setting of the first spring 13 enables the V-shaped plate 7 to limit gears of different diameters. It should be noted that when marking gears of different diameters, only gears of the same specification can be processed each time, and gears of different specifications need to be marked in batches. After the gears are placed, the first motor 24 is started at this time, the first motor 24 drives the reciprocating screw rod 43 to rotate, and the reciprocating screw rod 43 rotates to make the moving plate 25 move back and forth, and when the moving plate 25 moves to the right, the gear at the lower end moves to the right. It should be noted that the height of the supporting block 50 is between the height of one gear and the height of two gears, so when the moving plate 25 moves to the right, it can only push one gear to the right. When the gear moves to the right, it moves with the right guide plate 12, and the two sides of the guide plate 12 are inclined, so that the gear moves forward and backward when it moves to the right, so that the gear moves to the position of the arc-shaped groove 35. At this time, the moving plate 25 moves to the left, and the two guide plates 12 limit the gear, and the laser head 2 is marked. When the moving plate 25 moves to the left and separates from the lower end of the V-shaped plate 7, the left gear moves under the action of gravity, and then the moving plate 25 moves to the right to push the next gear. When the second gear moves to the right, it will contact the gear clamped by the guide plate 12, so that the previous gear is pushed to the right by the second gear, so that the processed gear is separated from the arc-shaped groove 35. The left side of the guide plate 12 is inclined, which can facilitate the gear to enter the arc-shaped groove 35, and the right side is inclined. When the two guide plates 12 move close to each other under the action of the second spring 37, there is a rightward pushing force on the processed gear, which facilitates the unloading of the gear. In this way, when processing, the worker only needs to place the gears between the two V-shaped plates 7 in advance, and then move the moving plate 25 back and forth to realize the positioning of the gears under the laser head 2 in turn. At the same time, automatic unloading can be realized in continuous work, and workers do not need to continuously load the machine, which effectively reduces the workload of workers and improves the working efficiency of gear marking. At the same time, the device can process gears of different diameters, thereby improving the applicability of the device.

[0044] As Figure 1 shown, the upper and lower positions of the opposite ends of the two V-shaped plates 7 are fixedly connected with the first limiting rods 6, and the rod wall of the first limiting rod 6 is slidably connected with the vertical plate 5. The first limiting rod 6 makes the V-shaped plate 7 more stable when moving.

[0045] As Figure 4As shown, both sides of the inner wall of the arc groove 35 are rotatably connected to the limiting circular blocks 32, and the two limiting circular blocks 32 at the front and rear are inside the arc groove 35. In this way, the gear is limited by the positions of four points, so that when limiting gears of different diameters, the gear can be made more stable.

[0046] like Figure 2 、 Figure 9 and Figure 10 As shown, the left side of the workbench 1 is fixedly connected to the air cylinder 23, and the interior of the air cylinder 23 is slidably connected to the piston block 45. The piston block 45 can move left and right inside the air cylinder 23. The right side of the piston block 45 is fixedly connected to the connecting rod 47. The movement of the connecting rod 47 drives the piston block 45 to move. The left side of the upper end of the workbench 1 is slidably connected to the slide 26. The interior of the slide 26 is slidably connected to the slider 46. The slider 46 can move inside the slide 26. The left side of the slider 46 is fixedly connected to the connecting rod 47. The movement of the movable plate 25 drives the slider 46 to move. 6 drives the connecting rod 47 to move. The connecting rod 47 is hollow, and its left side is connected to the interior of the gas cylinder 23. The gas inside the gas cylinder 23 can be introduced into the interior of the first gas pipe 44 through the connecting rod 47. The right side of the connecting rod 47 is fixedly connected to the first gas pipe 44. The upper end of the movable plate 25 is slidably connected to the rectangular plate 40. The rectangular plate 40 can move up and down relative to the movable plate 25. The upper end of the first gas pipe 44 is connected to the upper end of the rectangular plate 40. The interior of the rectangular plate 40 is evenly connected to a rotating block 41, which can rotate at the upper end of the rectangular plate 40.

[0047] When the movable plate 25 moves to the right, it drives the slider 46 to move to the right inside the slide groove 26, and the slider 46 drives the connecting rod 47 to move to the right. The connecting rod 47 drives the piston block 45 to move to the right, so that the air pressure inside the air cylinder 23 on the right side of the piston block 45 increases, and the gas enters the interior of the first air pipe 44 through the connecting rod 47, and then enters the position of the upper end of the movable plate 25. The air pressure at the upper end of the movable plate 25 increases, so that the rectangular plate 40 moves upward, and the rectangular plate 40 drives the rotating block 41 to move, which has an upward supporting effect on the gear that has not been pushed out. In this way, when the gear is pushed out, the movement of the rectangular plate 40 can support the gear that has not been pushed out upward. This can avoid the friction caused by the relative movement of the gear that has not been pushed out and the upper end of the movable plate 25 as much as possible, avoid the wear of the lower end of the gear, and improve the processing effect.

[0048] like Figure 10 As shown, second limiting rods 42 are fixedly connected to both sides of the upper end of the movable plate 25, and the rod wall of the second limiting rod 42 is slidably connected to the inside of the rectangular plate 40. By setting the second limiting rod 42, the rectangular plate 40 can be limited in its upward movement to prevent the rectangular plate 40 from separating from the movable plate 25.

[0049] like Figure 2As shown, an inclined slot 15 is provided on the right side of the workbench 1, and a third rod 9 is slidably connected to the front and rear positions of the right side of the inclined slot 15. A baffle 8 is fixedly connected to the left side of the third rod 9, and a third spring 10 is sleeved on the right side of the rod wall of the third rod 9. When the gear is extruded, it slides to the right side of the workbench 1 under the action of the inclined slot 15.

[0050] like Figure 2 、 Figure 3 and Figure 6 As shown, the upper end of the workbench 1 is slidably connected to a square rod 16, the lower end of the square rod 16 is fixedly connected to a round block, the upper end of the round block is fixedly connected to a fourth spring 27, and the fourth spring 27 has an upward supporting force on the round block, the upper end of the square rod 16 is fixedly connected to a placement plate 17, the gear to be marked is placed on the upper end of the placement plate 17, the upper end of the workbench 1 is provided with a groove 38 that matches the placement plate 17, the groove 38 enables the placement plate 17 to be embedded in the interior of the workbench 1, avoiding the placement plate 17 affecting the movement of the movable plate 25, the interior of the workbench 1 is provided with a vertical groove 28, and the lower end of the workbench 1 is fixed A second motor 20 is fixedly connected, and the second motor 20 is a driving device. In the prior art, the output end of the second motor 20 is fixedly connected to a threaded rod 21, and the second motor 20 drives the threaded rod 21 to rotate. The rod wall of the threaded rod 21 is threadedly connected with a rectangular block 33. The threaded rod 21 rotates, so that the rectangular block 33 moves up and down inside the cavity 18. The upper end of the square rod 16 is provided with a cavity 18, and the rectangular block 33 is located inside the cavity 18. A circular groove 34 is provided inside the square rod 16. The diameter of the circular groove 34 is larger than the diameter of the threaded rod 21. When the threaded rod 21 rotates, it will not affect the square rod 16.

[0051] In the initial state, under the action of the fourth spring 27, the upper end of the square rod 16 is located at the upper end position of the V-shaped plate 7. At this time, the staff will place the gears to be processed on the upper end of the placement plate 17 in turn. Under the action of gravity, the square rod 16 continues to move downward. During this process, the threaded rod 21 does not affect the movement of the square rod 16, and the rectangular block 33 moves relative to the cavity 18. When the gear is placed, the second motor 20 works to drive the threaded rod 21 to rotate. The rotation of the threaded rod 21 causes the rectangular block 33 to move downward. The movement of the rectangular block 33 limits the square rod 16 to prevent the square rod 16 from moving upward during work. In this way, when placing the gear, the fourth spring 27 makes the square rod 16 have a certain supporting effect on the gear, and will not cause the gear to move quickly downward to the bottom position of the V-shaped plate 7, which is more convenient when placing the gear.

[0052] like Figure 2 、 Figure 4 and Figure 9As shown, the upper end of the workbench 1 is provided with a leakage hole 29, so that the dust can pass through the leakage hole 29, the inside of the workbench 1 is fixedly connected with a filter plate 31, the filter plate 31 can pass through the air and block the dust, the lower end left side of the air cylinder 23 is fixedly connected with a second air pipe 22, the right side of the second air pipe 22 is fixedly connected with a first one-way valve 49, the left side of the air cylinder 23 is fixedly connected with a second one-way valve 48, the first one-way valve 49 and the second one-way valve 48 are prior art, the filter plate 31 is inclined, and the inclined arrangement has a certain guiding effect, the inside right side of the workbench 1 is provided with a guide groove 30, and the inside right side of the workbench 1 is placed with a dirt box 19 for collecting dust.

[0053] When the piston block 45 moves to the right, the second one-way valve 48 is in a closed state, and the first one-way valve 49 is in an open state, so that when the left side of the air cylinder 23 generates low pressure, the right side of the second air pipe 22 generates downward airflow, thereby adsorbing the dust on the upper end of the workbench 1, and then guiding the dust into the dirt box 19 through the guide groove 30, when the piston block 45 moves to the left, the first one-way valve 48 is in an open state, and the second one-way valve 49 is in a closed state, so that after each marking work is finished, the dust is sucked through the second air pipe 22, avoiding the dust remaining on the upper end of the workbench 1, affecting the gear machining, at the same time, the workbench 1 does not need to be cleaned by the staff, further saving manpower and improving use effect.

[0054] The application also provides a kind of suitable for above, including following steps:

[0055] Working principle: When working, the gear to be marked is placed between the two V-shaped plates 7. Under the action of the first spring 13, the front and rear two V-shaped plates 7 limit the gear. The setting of the first spring 13 enables the V-shaped plate 7 to limit the gears of different diameters. It should be noted that when marking gears of different diameters, only gears of the same specification can be processed each time, and gears of different specifications need to be marked in batches. After the gear is placed, the first motor 24 is started, and the first motor 24 drives the reciprocating screw 43 to rotate. The rotation of the reciprocating screw 43 causes the movable plate 25 to reciprocate left and right. When the movable plate 25 moves to the right, it moves to the right against the gear at the bottom. It should be noted that the height of the support block 50 is between the height of one gear and two gears, so when the movable plate 25 moves to the right, it can only move to the right against one gear. When the gear moves to the right, it moves with the guide plate 12 on the right. The two sides of the guide plate 12 are inclined, so when the gear moves to the right, the front and rear guide plates 12 move forward and backward respectively, thereby moving the gear to the position of the arc groove 35. At this time, the movable plate 25 moves to the left, and the two guide plates 12 limit the gear. , marking is performed by the laser head 2, when the movable plate 25 moves to the left and disengages from the lower end of the V-shaped plate 7, the gear on the left moves under the action of gravity, and then the movable plate 25 moves to the right, pushing the next gear. When the second gear moves to the right, it will contact the gear clamped by the guide plate 12, so that the previous gear is pushed to the right by the second gear, thereby causing the processed gear to disengage from the arc groove 35. The inclined setting on the left side of the guide plate 12 can facilitate the gear to enter the arc groove 35. The inclined setting on the right side, when the two guide plates 12 approach each other under the action of the second spring 37, After the gear is processed, it has a rightward thrust, which is convenient for unloading the gear. In this way, during processing, the staff only needs to place the gear between the two V-shaped plates 7 in advance, and then continuously move the movable plate 25 left and right to realize that the gear is located at the lower end position of the laser head 2 in sequence. At the same time, it can automatically unload the material during continuous work, and there is no need for the staff to continuously stay at the side of the machine to load the material, which effectively reduces the workload of the staff and improves the working efficiency of gear marking. At the same time, the device can process gears of different diameters, thereby improving the applicability of the device.

[0056] Furthermore, when the movable plate 25 moves to the right, it drives the slider 46 to move to the right inside the slide groove 26, and the slider 46 drives the connecting rod 47 to move to the right, and the connecting rod 47 drives the piston block 45 to move to the right, so that the air pressure inside the air cylinder 23 at the right side of the piston block 45 increases, and the air enters the interior of the first air pipe 44 through the connecting rod 47, and then enters the position of the upper end of the movable plate 25. The air pressure at the upper end of the movable plate 25 increases, so that the rectangular plate 40 moves upward, and the rectangular plate 40 drives the rotating block 41 to move, which has an upward supporting effect on the gear that has not been pushed out. In this way, when the gear is pushed out, the movement of the rectangular plate 40 can support the gear that has not been pushed out upward, so that the friction generated by the relative movement of the gear that has not been pushed out and the upper end of the movable plate 25 can be avoided as much as possible, thereby avoiding wear of the lower end of the gear and improving the processing effect.

[0057] Furthermore, in the initial state, under the action of the fourth spring 27, the upper end of the square rod 16 is located at the upper end position of the V-shaped plate 7. At this time, the staff will place the gears to be processed on the upper end of the placement plate 17 in sequence. Under the action of gravity, the square rod 16 continues to move downward. During this process, the threaded rod 21 does not affect the movement of the square rod 16, and the rectangular block 33 moves relative to the cavity 18. When the gear is placed, the second motor 20 works to drive the threaded rod 21 to rotate. The rotation of the threaded rod 21 causes the rectangular block 33 to move downward. The movement of the rectangular block 33 limits the square rod 16 to prevent the square rod 16 from moving upward during work. In this way, when placing the gear, the fourth spring 27 allows the square rod 16 to have a certain supporting effect on the gear, and the gear will not move quickly downward to the bottom position of the V-shaped plate 7, which is more convenient when placing the gear.

[0058] Furthermore, when the piston block 45 moves to the right, the second one-way valve 48 is in a closed state and the first one-way valve 49 is in an open state. In this way, when low pressure is generated on the left side of the air cylinder 23, a downward airflow is generated on the right side of the second air pipe 22, thereby adsorbing the dust on the upper end of the workbench 1, and then introducing the dust into the dirt storage box 19 through the guide groove 30. When the piston block 45 moves to the left, the first one-way valve 48 is in an open state and the second one-way valve 49 is in a closed state. In this way, after each marking work is completed, the dust is sucked away through the set second air pipe 22 to prevent dust from remaining on the upper end of the workbench 1 and affecting the processing of the gear. At the same time, there is no need for staff to clean the workbench 1, which further saves manpower and improves the use effect.

[0059] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
