[0001] The invention relates to the technical field of machine tool equipment, in particular to a full-automatic flying cutter chamfering machine. Background Art

[0002] In the field of mechanical processing, chamfering of workpieces is a common and important process. Chamfering can not only improve the appearance quality of the workpiece, but also enhance the assembly performance and stress bearing capacity of the workpiece.

[0003] In the current mechanical processing industry, the traditional method for chamfering workpieces mainly relies on manual operation, that is, workers manually chamfer the workpieces one by one. This method is not only time-consuming and labor-intensive, but also inefficient. In addition, the processing quality is often limited by the workers' skill level and fatigue level, making it difficult to ensure consistency.

[0004] In order to improve processing efficiency and quality, the industry has begun to turn to automated processing technology. However, most of the existing automated chamfering equipment still adopts a single-station processing mode, that is, the workpieces need to be placed on the processing station one by one, and after the processing is completed, the next workpiece is taken out and placed. Although this processing method has improved the processing accuracy to a certain extent, since the workpieces still need to be processed one by one, the overall processing efficiency is still limited and cannot meet the needs of large-scale and high-efficiency production.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions of various embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments described in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1: Figures 1 to 11As shown, the fully automatic flying knife chamfering machine of the present invention includes a driving motor A1, and the driving motor A1 is connected to a clamping disk 2 through a transmission mechanism. A plurality of workpiece positions 3 are arranged at equal intervals on the edge of the clamping disk 2. The transmission mechanism converts the continuous rotation of the driving motor A1 into the intermittent rotation of the clamping disk 2. The driving motor A1 is also connected to a multi-directional reciprocating mechanism, and the multi-directional reciprocating mechanism is simultaneously connected to a processing part and a clamp 4. When the clamping disk 2 is in a rotation gap, the multi-directional reciprocating mechanism controls the processing part to approach the clamping disk 2 to process the workpiece, and at the same time controls the clamp 4 to press and fix the corresponding workpiece on the clamping disk 2.

[0035] The disc-type clamp plate 2 cooperates with several workpiece positions 3 arranged at equal intervals on the edge to realize continuous processing of workpieces. Compared with the automatic chamfering equipment with a single workstation, the multiple workstations in the technical solution of the present invention can work simultaneously, so that while the equipment is processing one workpiece, other workstations are also preparing other workpieces, thereby improving the utilization rate of the equipment and reducing the waste of equipment and human resources. The simultaneous operation of multiple workstations significantly improves the overall processing efficiency of the equipment and meets the needs of large-scale and high-efficiency production.

[0036] The multi-directional reciprocating mechanism includes a cam 5, which is connected to a connecting rod 6. One end of the connecting rod 6 is provided with a matching wheel A7 that abuts against the cam 5, and the other end is fixedly connected to the processing portion. The processing portion is slidably arranged on a processing table 8. A spring is also arranged between the connecting rod 6 and the processing table 8. The outer side surface of the cam 5 is provided with a special-shaped convex ring 9. The outer side surface of the special-shaped convex ring 9 is provided with a high step surface 10 and a low step surface 11. The high step surface 10 and the low step surface 11 are connected by an inclined surface 12. The outer side surface of the special-shaped convex ring 9 A rotating part 13 is matingly connected, and a mating wheel B14 is provided at one end of the rotating part 13 to abut against the special-shaped convex ring 9, and an adjuster 15 is provided at the other end. The adjuster 15 is matingly connected with the clamp 4. When the mating wheel B14 abuts against the high step surface 10, the adjuster 15 presses the clamp 4 so that the clamp 4 presses and fixes the corresponding workpiece on the clamp disk 2. When the mating wheel B14 is out of contact with the high step surface 10, the adjuster 15 releases the clamp 4 to release the fixation of the workpiece.

[0037] By specifically debugging the multi-directional reciprocating mechanism, the fixture disk 2 and the transmission mechanism, when the fixture disk 2 is in the rotation gap, one of the workpiece positions 3 is aligned with the tool 24, and the cam 5 rotates and cooperates with the spring to make the tool holder 22 close to the fixture disk 2. At the same time, the high step surface 10 abuts against the matching wheel B14, and the adjuster 15 presses the clamp 4 so that the clamp 4 presses and fixes the workpiece on the workpiece position 3 to avoid movement or rotation of the workpiece during the processing. The drive motor B drives the tool 24 to rotate to achieve chamfering of the workpiece; after the processing is completed, the cam 5 pushes the tool holder 22 away from the fixture disk 2, and the matching wheel B14 is disengaged from the abutment with the high step surface 10, and the adjuster 15 releases the clamp 4, thereby releasing the fixation of the workpiece. At this time, the fixture disk 2 continues to rotate to the next workpiece position 3 to align with the tool 24, and then repeats the above process to achieve continuous processing of the workpiece.

[0038] The clamp 4 is adjustably arranged on a box body 16 , a slide rail A17 is fixedly arranged on the box body 16 , an adjusting slider A18 is slidably arranged on the slide rail A17 , a mounting block 19 is fixedly arranged on the adjusting slider A18 , and the clamp 4 is fixedly connected to the mounting block 19 .

[0039] A guide block 29 is also provided above the clamp plate 2, and the guide block 29 is fixedly connected to the mounting plate 28. A vertical plate 25 is fixedly provided on the box body 16, and a guide rail B26 is fixedly installed on the vertical plate 25. An adjusting slider B27 is slidably connected to the guide rail B26. The mounting plate 28 is fixedly connected to the adjusting slider B27.

[0040] The clamp 4 and the guide block 29 can be slidably arranged, which is conducive to the feeding and clamping of workpieces of different specifications. Compared with the conventional fixed arrangement, the structure is more flexible and has a higher fault tolerance rate.

[0041] The box body 16 is also provided with a mounting rod 20 which can be adjusted, and a pressing plate 21 is adjustably mounted on the mounting rod 20 . The pressing plate 21 is located at the side of the clamping plate 2 and presses the workpiece along the axial direction.

[0042] By setting the pressing plate 21, the vibration during the rotation of the clamp disk 2 can be avoided so as to prevent the workpiece from moving in the axial direction, and it can be ensured that when the workpiece reaches the processing position, its head is close to the clamp disk 2, so as to ensure the consistency and accuracy of the chamfering processing; the pressing plate 21 is connected to the mounting rod 20 by screws, and a U-shaped opening is provided on the pressing plate 21. The position of the pressing plate 21 on the mounting rod 20 can be adjusted by adjusting the specific position of the screw in the U-shaped opening, and the angle of the pressing plate 21 can also be adjusted to meet the demand of clamping the workpiece. The mounting rod 20 is connected to the box body 16 by screws or bolts, and the distance between the pressing plate 21 and the clamp disk 2 can be controlled by adjusting the specific position of the mounting rod 20, so as to meet the clamping requirements of workpieces of different specifications.

[0043] The processing part includes a tool holder 22 slidably disposed on the processing table 8 , a tool 24 is disposed on the tool holder 22 , and a driving motor B23 is also fixedly mounted on the tool holder 22 , and the driving motor B23 controls the rotation of the tool 24 .

[0044] The selection of the tool 24 needs to be determined according to the specific workpiece and processing parameters. The tool 24 can be a single-head tool or a multi-head tool.

[0045] The device further comprises a feeding mechanism, which comprises a vibration plate 30 . A conveying track 31 is arranged at the outlet of the vibration plate 30 . The outlet of the conveying track 31 is arranged above the fixture plate 2 .

[0046] The feeding mechanism can also be other devices such as a robot, and technical personnel in this field can set it according to actual needs. Of course, it is also possible not to set up an automatic feeding mechanism, and directly load the materials manually. However, this operation has certain risks and requires corresponding training and relevant protection. For example, wearing gloves is not allowed, and a protective plate is set above the tool 24 to prevent the operator from directly contacting the tool 24, etc. Specific measures are adjusted according to actual conditions.

[0047] The clamping disc 2 is also provided with a discharge slope 32. After the processed workpiece is separated from the clamping disc 2, it is discharged through the discharge slope 32. The processing table 8 is also provided with a waste chip discharge port 33. The processing table 8 is provided with a slide rail C34. A protective cover 35 is slidably provided on the slide rail C34. The protective cover 35 is also provided with an observation window 36.

[0048] The setting of the discharge ramp 32 realizes the collection of the processed workpieces. One end of the discharge ramp 32 is set on the side of the clamp disk 2. After the workpiece reaches this position, it separates from the clamp disk 2 under its own gravity and falls onto the discharge ramp 32. A collection frame can be set at the other end of the discharge ramp 32 to facilitate the collection of the processed workpieces and transport them to the next processing equipment.

[0049] The controller 37 is also included, and the controller 37 is electrically connected to the vibration plate 30, the driving motor A1 and the driving motor B23.

[0050] The transmission mechanism in the above embodiment converts the continuous rotation of the driving motor A1 into the intermittent rotation of the clamping plate 2. The transmission mechanism can be implemented by various existing structures, such as a groove wheel indexing mechanism, a ratchet mechanism, a cam intermittent motion mechanism and an incomplete gear mechanism. The specific structure to be adopted is set according to actual needs. The specific structure of a transmission mechanism (ratchet mechanism) is provided as follows: A driving wheel is connected to the output shaft of the driving motor A1, and the driving wheel is connected to a driven wheel through a transmission belt. The driven wheel is fixedly connected to the main shaft. The main shaft is rotatably arranged in the box body 16. The main shaft is fixedly connected to the cam 5. A bevel gear A is also arranged on the main shaft. The bevel gear A is meshingly connected with the bevel gear B. The axial direction of the bevel gear B is parallel to the axial direction of the clamp disk 2. A turntable is coaxially fixed on the bevel gear B. A rocker is arranged on the turntable. A pawl is arranged at the end of the rocker. The clamp disk 2 is coaxially fixed with a ratchet. The pawl is cooperatively connected to the ratchet. The continuous reciprocating swing of the rocker enables the ratchet to rotate intermittently.

[0051] The above-mentioned ratchet mechanism is only one of the feasible structures. In actual production, even the ratchet mechanism has a variety of feasible solutions, and those skilled in the art can set it according to actual conditions.

[0052] In order to control the rotation speed of the cam 5 and the clamping plate 2, a reducer can be set according to actual conditions. The specific setting of the reducer can be carried out by technical personnel in this field as needed. This part can be achieved by existing technologies and will not be repeated here.

[0053] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive from any point of view. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0054] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
