Description

Technical Field

[0001] The invention relates to the technical field of toothed disc processing, and in particular to a die-casting toothed disc processing machine. Background Art

[0002] The toothed disc is a commonly used mechanical part. The processing method of the toothed disc is usually to die-cast the main body of the toothed disc first, and then process the teeth on the toothed disc. In the process of pressure casting, burrs are inevitable due to factors such as pressure shock and insufficient clamping force. In order to solve the problem of burrs, various deburring methods have emerged, and the deburring process has also developed from early manual and mechanical operations to automation. At present, common deburring methods include drum grinding, high temperature deburring, mechanical brush deburring, extrusion honing deburring, magnetic grinding, water jet deburring and other methods. In recent years, with the rapid development of laser technology, and because laser processing has the advantages of non-contact and green environmental protection, the use of laser deburring has gradually been more and more widely used.

[0003] At present, when using laser to remove burrs at the center hole of the gear disc, the gear disc is first placed in a laser deburring device, and the burrs at the center hole of the gear disc are aligned with the laser, and then the laser emits a laser to remove the burrs at the center hole of the gear disc. However, after the burrs at the center hole of the gear disc are removed, the laser will pass through the center hole of the gear disc and irradiate onto the table top of the device, and the laser will be reflected by the table top of the device to the surface of the gear disc, which will cause the laser to irradiate positions that should not be irradiated, thereby affecting the table top of the device and the parts of the gear disc where burrs do not need to be removed.

The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly understood.

[0032] It should be noted that the terms “front”, “rear”, “left”, “right” and similar expressions used in this document are only for illustrative purposes and do not represent the only implementation method.

[0033] Example 1

[0034] Combination Figure 1-Figure 3As shown, the present application provides a die-casting gear disc processing machine, including a base 1, a rotary feeding mechanism 2, a mounting seat 3, an open circular slide rail 4, an arc-shaped slider 5, a laser 6, a fixing block 7, a fastening bolt 8, a laser receiving body 9, a mounting block 91, a laser guide tube 10 and a reflective cone 11. A rotary feeding mechanism 2 is provided in the middle of the top of the base 1, a mounting seat 3 is connected to the right side of the top of the base 1, an open circular slide rail 4 is connected to the mounting seat 3, an arc-shaped slider 5 is slidably connected to the open circular slide rail 4, a laser 6 is installed on the upper part of the arc-shaped slider 5, and the arc-shaped slider 5 A fixing block 7 is sleeved on the outside, and the fixing block 7 is fixedly connected to the right side of the open circular slide rail 4. A fastening bolt 8 is connected to the fixing block 7 by a threaded connection. A mounting block 91 is connected to the lower part of the arc-shaped slide block 5. A laser receiving body 9 is connected to the top of the mounting block 91. The shape of the laser receiving body 9 is spherical. A laser guide tube 10 is connected to the top of the laser receiving body 9. The entrance of the laser guide tube 10 is aligned with the emission port of the laser 6. The laser receiving body 9 and the laser guide tube 10 are both made of high-temperature resistant metal. At least eight reflection cones 11 are connected at intervals in the laser receiving body 9.

[0035] Combination Figure 4-Figure 6 As shown, the rotary feeding mechanism 2 includes a first motor 21, a rotating frame 22, a second motor 23, a circular block 24, a mounting plate 25, a reduction box 26 and a hollow support plate 27. The first motor 21 is installed in the middle of the top of the base 1, and the rotating frame 22 is connected to the first motor 21. Six second motors 23 are installed at intervals at the lower part of the rotating frame 22. A circular block 24 is connected to the top of the rotating frame 22. Six mounting plates 25 are connected to the outer wall of the circular block 24 at intervals along the circumferential direction. The bottom of the six mounting plates 25 is provided with a reduction box 26. The second motor 23 is connected to the input end of the adjacent reduction box 26. The six mounting plates 25 are rotatably connected to the hollow support plate 27, and the hollow support plate 27 is connected to the output end of the adjacent reduction box 26.

[0036] The toothed disc is manually placed into the hollow support disc 27, and then the position and angle of the laser 6 are adjusted according to the position and angle of the burr at the center hole of the toothed disc. When adjusting, first loosen the fastening bolts 8 to loosen the arc slider 5, and then slide the arc slider 5 on the open circular slide rail 4. This can change the position and angle of the laser 6, so that the emission port of the laser 6 is aligned with the burr at the center hole of the toothed disc, which can help improve the quality and efficiency of deburring. After the emission port of the laser 6 is aligned with the burr at the center hole of the toothed disc, tighten the fastening bolts 8 to fix the arc slider 5. The laser 6 emits laser light, which scans the burrs at the center hole of the toothed disc, thereby melting and vaporizing the burrs, and finally removing the burrs; the second motor 23 works through the deceleration effect of the reduction box 26, which can make the hollow support disc 27 rotate slowly, and the slow rotation of the hollow support disc 27 can make the toothed disc inside it rotate slowly, so that all the burrs around the center hole of the toothed disc can be removed by the laser; and when the laser is removing the burrs, the flowing protective gas is continuously introduced on the circumferential outer side of the laser, so that a continuous closed protective atmosphere is formed in the melting area, which takes away the heat generated by the thermal effect of the laser on the toothed disc, and improves the quality of the toothed disc surface after laser deburring. Since the entrance of the laser guide tube 10 is aligned with the emission port of the laser 6, when the burrs at the center hole of the toothed disc are removed by the laser, the laser passes through the center hole of the toothed disc and enters the laser receiving body 9 through the laser guide tube 10. The laser in the laser receiving body 9 will be reflected multiple times in the laser receiving body 9 under the reflection action of the reflection cone 11, and the energy is gradually consumed. Since the shape of the laser receiving body 9 is spherical, the laser will not be reflected from the laser receiving body 9. Since the laser receiving body 9 and the laser guide tube 10 are both made of high temperature resistant metal, the laser receiving body 9 and the laser guide tube 10 will not be melted by the laser. In this way, the effect of being able to receive the laser and avoiding the laser from irradiating the position where it should not be irradiated is achieved, which can further help improve the quality and efficiency of deburring. The first motor 21 drives the rotating frame 22 to rotate intermittently. The intermittent rotation of the rotating frame 22 drives the mounting plate 25 to rotate intermittently through the circular block 24. The intermittent rotation of the mounting plate 25 can make the hollow supporting plate 27 rotate with the gear disc therein, so that the gear disc after deburring can be rotated away from the laser 6, so that the next gear disc that needs to be deburred can be rotated to align with the laser 6.

[0037] Example 2

[0038] Based on Example 1, Figure 1 and Figure 7As shown, a cooling mechanism 12 is also included. The outer wall of the laser housing 9 is provided with a cooling mechanism 12. The cooling mechanism 12 includes a spherical shell 121, a connecting block 122, an infusion tube 123 and an arc guide plate 124. The outer wall of the laser housing 9 is sleeved with a spherical shell 121, and the spherical shell 121 is fixedly connected to the mounting block 91. The left and right sides of the spherical shell 121 are connected to the infusion tube 123. The left and right sides of the mounting block 91 are connected to the connecting blocks 122. The two infusion tubes 123 pass through the two connecting blocks 122 respectively. Eight arc guide plates 124 are connected between the inner wall of the spherical shell 121 and the outer wall of the laser housing 9.

[0039] Connect the left infusion tube 123 to an external water pump, and then turn on the water pump. Cold water enters the spherical shell 121 through the left infusion tube 123. The cold water in the spherical shell 121 can be guided by the arc-shaped guide plate 124 to make the cold water evenly distributed on the outside of the laser housing 9. The cold water is then discharged through the right infusion tube 123. The cold water can take away the heat on the laser housing 9 to cool the laser housing 9. When there is no need to cool the laser housing 9, turn off the water pump.

[0040] Example 3

[0041] Based on Example 2, Figure 1 , Figure 8 and Fig. 9 As shown, it also includes a blowing mechanism 13. The blowing mechanism 13 is provided on the front side of the mounting block 91. The blowing mechanism 13 includes a supporting block 131, an air outlet pipe 132 and a filter 133. The supporting block 131 is connected to the front side of the mounting block 91. The air outlet pipe 132 is connected inside the supporting block 131. The air outlet of the air outlet pipe 132 is aligned with the inlet of the laser guide tube 10. The air outlet of the air outlet pipe 132 is connected to the filter 133.

[0042] Connect the air outlet pipe 132 to an external air pump, and then turn on the air pump. The gas will then be blown toward the laser guide tube 10 through the air outlet pipe 132. This can blow away the fallen burrs and prevent the burrs from entering the laser guide tube 10 and the laser containing body 9. The filter net 133 can filter impurities and prevent impurities from being blown out from the air outlet pipe 132 and preventing impurities from entering the laser guide tube 10 and the laser containing body 9. When blowing is not needed, turn off the air pump.

[0043] Example 4

[0044] Based on Example 3, Figure 1 and Fig.10As shown, a material unloading mechanism 14 is also included. A material unloading mechanism 14 is provided on the left side of the top of the base 1. The material unloading mechanism 14 includes a connecting plate 141, a storage barrel 142, a ring 143 and a baffle 144. The connecting plate 141 is connected to the left side of the top of the base 1. The storage barrel 142 is connected to the connecting plate 141. The storage barrel 142 is located on the upper side of the hollow support disk 27. The top of the circular block 24 is connected to a ring 143. Six baffles 144 are connected to the outer wall of the ring 143 at intervals along the circumferential direction. The baffle 144 is located on the lower side of the storage barrel 142. Each baffle 144 is in contact with its two adjacent hollow support disks 27.

[0045] Multiple toothed discs are neatly placed into the storage barrel 142, and the toothed disc at the bottom of the storage barrel 142 falls into the hollow supporting disc 27. The circular block 24 rotates intermittently to drive the baffle 144 to rotate intermittently through the circular ring 143. When the hollow supporting disc 27 aligned with the storage barrel 142 turns away from the storage barrel 142, one of the baffles 144 rotates to align with the storage barrel 142, and the baffle 144 can block the toothed disc in the storage barrel 142 to prevent the toothed disc in the storage barrel 142 from falling. After the next hollow supporting disc 27 rotates to align with the storage barrel 142, the toothed disc in the storage barrel 142 falls into the hollow supporting disc 27, and the cycle repeats. Material unloading can be repeated, and there is no need to manually place the toothed discs into the hollow supporting disc 27 one by one, thereby saving loading time.

[0046] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
