[0002] Alloy accessories refer to accessories made of alloys, or alloy materials mixed into metal materials and then made of this material. Alloy materials can change the performance of accessories and increase the hardness of accessories. Depending on the application scenario, the requirements for the alloy composition of accessories are also different. For example, common alloy tools use their high hardness to cut the excess of shaft sleeve blanks.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. A Geneva drive plate and a drive wheel are set on the top of the equipment. When in use, the servo motor drives the drive shaft to rotate counterclockwise, and the drive shaft drives the drive wheel to rotate counterclockwise, and the eccentric shaft is passed into the first shaft slot of the Geneva drive plate. As the eccentric shaft continues to rotate, the shaft slot drives the Geneva drive plate to rotate clockwise. When the eccentric shaft leaves the first shaft slot, the rotation of the Geneva drive plate is suspended. When the Geneva drive plate performs the above rotation, the turret also drives the knife seat to be welded to rotate clockwise, so that the first melting point at the top of the knife seat to be welded rotates to the bottom side of the material cabin, just leaking the bottom end to the first melting point on the top of the knife seat to be welded. The bottom end of the gold cutter head is welded to the melting point. At the same time, the second welding point at the top of the cutter seat to be welded reaches the bottom of the space bending part and is melted by high temperature. The servo motor rotates the drive shaft counterclockwise again, repeating the above rotation mode, and the eccentric shaft is passed into the next shaft slot of the Geneva drive plate. As the eccentric shaft continues to rotate until it leaves the shaft slot, the Geneva drive plate rotates and pauses again. The turret rotates the cutter seat to be welded clockwise again, so that the second melting point at the top of the cutter seat to be welded rotates to the bottom side of the material chamber again. The second alloy cutter head in the material chamber leaks downward and is welded to the second melting point at the top of the cutter seat to be welded. In this way, all alloy cutter heads are welded to the cutter seat to be welded in turn. During the welding process, the operator does not need to manually place the alloy cutter head, nor does he need to manually straighten the alloy cutter head, which improves the welding efficiency.

[0018] 2. The high-frequency heating tube is hinged on the equipment. Every time the knife seat to be welded rotates an angle, the spatial bending part on the high-frequency heating tube will heat the next heating point on the knife seat to be welded, and the high-frequency heating tube will deflect upward once. The spatial bending part does not fall completely on the knife seat to be welded, but when the knife seat to be welded rotates and transports the heating point to the bottom of the material cabin, the spatial bending part is lifted from the knife seat to be welded to prevent the non-welding position of the knife seat to be welded from being completely melted, causing unnecessary plastic deformation of the welding area of ​​the knife seat to be welded, affecting product quality.

DETAILED DESCRIPTION

[0027] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0028] In one embodiment, if Figure 1-Figure 7 As shown: This embodiment provides a laser welding device for alloy fitting production, including a base 1, a rotating mechanism 2 is fixed on the base 1, a feeding mechanism 3 located at the rear side of the rotating mechanism 2 is fixed on the base 1, and a manipulation mechanism 4 is provided in the base 1;

[0029] The rotating mechanism 2 includes a turret 5 fixed on the top of the base 1 and a driving wheel 6 fixed on the top of the base 1 and located near the turret 5. A positioning hole 7 is provided on the top of the turret 5. A Geneva driving plate 8 is fixed on the outer surface of the turret 5. An eccentric shaft 9 that matches the Geneva driving plate 8 is fixed on the top surface of the driving wheel 6. The bottom end of the tool holder 10 to be welded is positioned in the positioning hole 7. The feeding mechanism 3 includes a vertical plate 11 fixed on the top of the base 1, and also includes a material cabin 12 fixed on the top of the vertical plate 11 and extending forward to the top of the tool holder 10 to be welded. An operating chamber 13 is provided in the base 1. A driving shaft 14 is installed at the bottom end of the driving wheel 6. The bottom end of the driving shaft 14 enters the operating chamber 13. The operating mechanism 4 includes a servo motor arranged in the operating chamber 13. The servo motor 16, the operating mechanism 4 also includes a button 17 fixed on one side of the base 1, the button 17 is electrically connected to the servo motor 16, the bottom end of the drive shaft 14 is connected to the servo motor 16, the operating mechanism 4 also includes a high-frequency heating element installed on the base 1, the high-frequency heating element includes a support plate 23 fixed on one side of the top of the base 1 and a high-frequency heating tube 24, one end of the high-frequency heating tube 24 is transferred to the support plate 23, and a space bending portion 30 is provided at the free end, and the space bending portion 30 is buckled on the top of the knife seat 10 to be welded, the operating mechanism 4 also includes a tilting rod 25 sliding up and down on the support plate 23, the top of the tilting rod 25 is connected to the transfer end of the high-frequency heating tube 24, and the bottom end of the tilting rod 25 is downwardly located on the rotation trajectory of the eccentric shaft 9.

[0030] Working principle and effect, use the forward material chamber 12 to load multiple alloy cutter heads at a time, and then insert the bottom end of the cutter seat 10 to be welded into the positioning hole 7, the bottom end of the first alloy cutter head leaking out of the material chamber 12 will fall on the top of the cutter seat 10 to be welded in advance, then buckle the spatial bending portion 30 of the high-frequency heating tube 24 on the top of the cutter seat 10 to be welded, pass current into the high-frequency heating tube 24, the current heats the spatial bending portion 30, and the high heat melts the top buckling part of the cutter seat 10 to be welded, the right leg leans on the button 17 and clamps it hard, so that the servo motor 16 is energized to work, the servo motor 16 drives the drive shaft 14 to rotate counterclockwise, the drive shaft 14 drives the drive wheel 6 to rotate counterclockwise, the drive wheel 6 drives the eccentric shaft 9 to rotate, and the eccentric shaft 9 is passed into the first shaft groove of the Geneva drive plate 8, as the eccentric shaft 9 continues to rotate, the shaft groove drives the Geneva drive plate 8 to rotate clockwise, when the eccentric shaft 9 leaves the first shaft groove, the Geneva drive plate 8 rotates The rotation is paused. When the Geneva drive plate 8 performs the above rotation, the turret 5 will also rotate the tool holder 10 to be welded clockwise, so that the first melting point at the top of the tool holder 10 to be welded rotates to the bottom side of the material chamber 12, and the bottom end of the first alloy cutter head whose bottom end is leaked on the top of the tool holder 10 to be welded is welded to the melting point. At the same time, the second welding point at the top of the tool holder 10 to be welded reaches the bottom of the spatial bending portion 30 and is melted by high temperature. The servo motor 16 drives the drive shaft 14 to rotate counterclockwise again, repeating the above rotation mode, and delivering the eccentric shaft 9 to the next shaft groove of the Geneva drive plate 8. As the eccentric shaft 9 continues to rotate until it leaves the shaft groove, the Geneva drive plate 8 rotates and pauses again. The turret 5 drives the tool holder 10 to be welded to rotate clockwise again, so that the second melting point at the top of the tool holder 10 to be welded rotates to the bottom side of the material chamber 12 again, and the second alloy cutter head in the material chamber 12 leaks downward and is welded to the second melting point at the top of the tool holder 10 to be welded. By analogy, all the alloy tool heads are welded on the tool holder 10 to be welded in sequence ( Figure 7 As shown in the figure), during the welding process, the operator does not need to manually place the alloy cutter head, nor does he need to manually straighten the alloy cutter head, which improves the welding efficiency.

[0031] When the eccentric shaft 9 rotates to the bottom end of the tilting rod 25 (about to enter the shaft groove of the Geneva driving plate 8), the ball head 28 is used to contact the lifting wheel 27 in advance, so that the lifting wheel 27 deflects the tilting rod 25 to the upper left, and the tilting rod 25 deflects the ceramic seat 29 to the upper left, and the ceramic seat 29 deflects the high-frequency heating tube 24 to the upper left. At this time, the spatial bending portion 30 at the end of the high-frequency heating tube 24 also deflects upward and leaves the top of the knife seat 10 to be welded, and the eccentric shaft 9 enters the shaft groove of the Geneva driving plate 8 and pushes the Geneva driving plate 8 to rotate, and the Geneva driving plate 8 rotates the turret 5, and the turret 5 rotates the knife seat 10 to be welded. The eccentric shaft 9 rotates to rotate the melting point position on the knife seat 10 to be welded to the bottom of the material chamber 12. At the same time, the ball head 28 at the top of the eccentric shaft 9 leaves the lifting wheel 27, the lifting wheel 27 loses the squeezing effect and descends, the tilting rod 25 rotates to the lower right, the tilting rod 25 leads the ceramic seat 29 to rotate to the lower right, and the ceramic seat 29 leads the high-frequency heating tube 24 to rotate to the lower right. When the spatial bending portion 30 falls to the next welding position of the knife seat 10 to be welded again, the eccentric shaft 9 leaves the shaft groove of the Geneva driving plate 8, the Geneva driving plate 8 stops rotating, the knife seat 10 to be welded no longer rotates, and the spatial bending portion 30 heats the next welding point to a high temperature. It can be seen from this that every time the knife seat 10 to be welded rotates an angle, the spatial bending portion 30 on the high-frequency heating tube 24 will heat the next heating point on the knife seat 10 to be welded once. The spatial bending portion 30 does not completely fall on the knife seat 10 to be welded, but when the knife seat 10 to be welded rotates and transports the heating point to the bottom of the material chamber 12, the spatial bending portion 30 is lifted from the knife seat 10 to be welded, preventing the non-welding position of the knife seat 10 to be welded from being completely melted, causing unnecessary plastic deformation of the welding area of ​​the knife seat 10 to be welded, affecting product quality.

[0032] The left and right sides of the base 1 are provided with inclined surfaces, and the setting of the two inclined surfaces makes the base 1 gradually narrower from the rear end to the front. The button 17 is located on the inclined surface on the right side. The operator sits on the front side of the base 1 with his legs resting on the inclined surfaces on both sides and his right leg close to the button 17. When starting the servo motor 16, the operator only needs to squeeze the button 17 with the right leg. When the right leg squeezes the button 17 again, the servo motor 16 is powered off and shut down, which is convenient to operate.

[0033] like Figure 1 , Figure 3As shown, a circle of positioning rods 18 are installed on the top surface of the Geneva drive plate 8 through a hinge shaft, and a bending spring 19 is connected between the free end of the positioning rod 18 and the top surface of the Geneva drive plate 8. The bending spring 19 provides elastic force to the free end of the positioning rod 18, so that the free end of the positioning rod 18 is deflected into the positioning hole 7. When the bottom end of the knife seat 10 to be welded is placed in the positioning hole 7, all the positioning rods 18 rotate outward, and the bending spring 19 is compressed and shortened and stores elastic force. After the bottom end of the knife seat 10 to be welded is completely placed in the positioning hole 7, the bending spring 19 elastically lengthens and rotates all the positioning rods 18 back to the positioning hole 7 in a clamping and pushing manner. The clamping effect generated by the rotation of these positioning rods 18 into the positioning hole 7 is used to prevent the knife seat 10 to be welded from falling off. When the turret 5 rotates, it is ensured that the knife seat 10 to be welded is rotated with it.

[0034] like Figure 3 As shown, the positioning rod 18 is arc-shaped, and the free end of the positioning rod 18 is provided with a positioning portion 20 bent toward the positioning hole 7, and a chamfer 21 is provided downward along the inner edge of the top surface of the positioning rod 18. When the bottom end of the welding knife seat 10 is placed in the positioning hole 7, the bottom end first falls on the chamfer 21, forcing the positioning rod 18 to deflect outward, which is conducive to the bottom end of the welding knife seat 10 to fall into the positioning hole 7 quickly.

[0035] A damping bearing 22 is fixed to the top of the base 1, and the drive shaft 14 is assembled on the damping bearing 22, and the drive shaft 14 enters the base 1 through the damping bearing 22. After the servo motor 16 rotates the drive shaft 14 by one angle, the damping bearing 22 prevents the drive shaft 14 from rotating by inertia, ensuring that the angle of each rotation of the drive shaft 14 is consistent, ensuring that the angle of each rotation of the drive wheel 6 is consistent, ensuring that the angle of each rotation of the eccentric shaft 9 is consistent, ensuring that the angle of each rotation of the Geneva drive plate 8 is consistent, ensuring that the angle of each rotation of the tool holder 10 to be welded is consistent, and ensuring that all alloy tool heads are distributed in an array after being welded on the tool holder 10 to be welded.

[0036] A lifting wheel 27 is provided at the bottom end of the tilting rod 25, and a ball head 28 is provided at the top end of the eccentric shaft 9. The lifting wheel 27 is close to the outer side of the shaft groove of the Geneva driving plate 8. When the eccentric shaft 9 rotates with the ball head 28 until it is about to enter the shaft groove of the Geneva driving plate 8, the lifting wheel 27 is triggered first, and the lifting wheel 27 pushes the tilting rod 25 to rise in advance. A hinge groove 35 is provided at the top end of the support plate 23, and a ceramic seat 29 is fixed at the rotating end of the high-frequency heating tube 24. The ceramic seat 29 is transferred in the hinge groove 35 through a rotating shaft. The top end of the tilting rod 25 is connected to the ceramic seat 29, and the ceramic seat 29 is provided with an electrical port for providing thermal current to the high-frequency heating tube 24.

[0037] A spring plate 34 is fixed in the hinge groove 35. The spring plate 34 is tilted upward and supported on the bottom end of the high-frequency heating tube 24. After the high-frequency heating tube 24 falls downward, the bottom surface falls on the spring plate 34, and its falling range is limited by the spring plate 34 to ensure that the lifting wheel 27 is always on the rotation trajectory of the eccentric shaft 9.

[0038] The material chamber 12 includes a large bucket chamber 31 at the top and a small bucket chamber 32 connected to the bottom of the large bucket chamber 31. The small bucket chamber 32 is vertically downward. In addition to a discharge port at the bottom of the small bucket chamber 32, a discharge side port 33 that is consistent with the rotation direction of the tool holder 10 to be welded is also opened on the side of the small bucket chamber 32. The large bucket chamber 31 at the top is convenient for placing multiple alloy tool bits at one time, and the small bucket chamber 32 is convenient for feeding a single alloy tool bit downward. When the tool holder 10 to be welded continues to rotate clockwise, the welded alloy tool bit is brought to the next position through the discharge side port 33, and the tool holder 10 to be welded sends the next point to be welded into the bottom of the small bucket chamber 32, and so on, and finally all the alloy tool bits are pressed. Figure 7 The welding is complete as shown.

[0039] The present invention also provides a laser welding process for alloy fitting production, which is applicable to the above-mentioned laser welding device for alloy fitting production, and comprises the following steps:

[0040] Step S01, measuring the diameter of the tool holder 10 to be welded, calculating the number of alloy tool bits according to the measured diameter value, and loading these alloy tool bits into the material cabin 12;

[0041] Step S02, insert the bottom end of the knife holder 10 to be welded into the positioning hole 7 and lock it;

[0042] Step S03, the servo motor 16 drives the tool holder 10 to be welded to rotate intermittently, the high-frequency heating tube 24 heats the top of the tool holder 10 to be welded, and the alloy tool heads are dropped from the material chamber 12 to the top of the tool holder 10 to be welded, and these alloy tool heads are welded to the top of the tool holder 10 to be welded in sequence.
