Description

Technical Field

[0001] The present application relates to the technical field of gear part deburring, and in particular to a gear part deburring device. Background Art

[0002] Removing burrs from stamped parts is one of the most important post-process items after stamping production. There are many kinds of burr removal processes and methods, such as machine tool cutting, belt grinding, brushing, drum grinding, vibration grinding, sandblasting, etc., with different advantages and disadvantages, but they all have one thing in common, that is, during the burr removal process, there will always be a little burr residue in one direction that will be squeezed and lodged (attached) on the side of the workpiece, especially in machining methods (such as machine tool cutting, belt grinding, etc.).

[0003] Relatively speaking, vibration grinding, belt grinding and other methods are slightly better in removing burrs, but the former is not ideal for removing burrs from fine gear stampings, and the environmental pressure is increasing. Although the latter is more and more widely used in post-process equipment for removing burrs from stampings, it will still produce inverted burrs on the side of the workpiece in a certain direction (facing away from the grinding direction). Therefore, in situations with higher requirements, a brush power head is generally added to the belt grinding to assist in removing the burrs produced on the side.

[0004] However, for gear-type stamping parts, due to the concave shape of the teeth, the burrs on their sides are distributed almost all around the circumference. Therefore, those brush power heads that usually only focus on a fixed direction cannot cope with such burrs that are all around the circumference. Summary of the invention

[0024] Reference Figures 1 to 6 The embodiment of the present application provides a deburring device for a gear part 500 , including: a machine base 100 , a conveying mechanism 200 , a grinding mechanism 300 and a discharging mechanism 400 .

[0025] Reference Figures 1 to 4The conveying mechanism 200 is used to convey the gear member 500 . Specifically, the conveying mechanism 200 includes a turntable 210, a fixing portion 220 and a tooth template 230. The turntable 210 is rotatably arranged on the machine base 100. The fixing portion 220 is provided with multiple and circumferentially arranged on the turntable 210. The fixing portion 220 includes a pin 221 and a mounting seat 410. The pin 221 is arranged on the turntable 210. The pin 221 is used to install the gear member 500. The mounting seat 410 is slidably sleeved on the pin 221 and is located below the turntable 210. The mounting seat 410 is provided with multiple push rods 411 around the pin 221 as the center. The push rods 411 penetrate the turntable 210. The tooth template 230 is arranged on one side of the fixing portion 220. The tooth template 230 is provided with a tooth portion 231. The tooth portion 231 is coaxial with the turntable 210. The tooth portion 231 can be meshed and connected with the gear member 500, so that the gear member 500 rotates around the pin 221. The gear part 500 is installed on the pin shaft 221, and the turntable 210 rotates to drive the gear part 500 to rotate, thereby realizing the revolution of the gear part 500; when the turntable 210 drives the gear part 500 to enter the tooth template 230, the tooth portion 231 meshes with the gear part 500, so that the gear part 500 rotates while revolving.

[0026] Furthermore, the fixing part 220 further includes a disc 222, which is located above the rotating disk 210. The disc 222 is used to support the gear part 500, and the top rod 411 is passed through the disc 222. By supporting the gear part 500 through the disc 222, the contact area between the fixing part 220 and the gear part 500 can be increased, thereby ensuring the stability of the gear part 500. Among them, the disc 222 is provided with a concave ring, thereby reducing the friction between the disc 222 and the gear part 500 and improving the product quality.

[0027] In some embodiments of the present application, the base 100 is provided with a fixed disk 110 above the rotating disk 210, and the tooth template 230 is provided on the fixed disk 110. In this case, the tooth portion 231 is provided on the side of the tooth template 230 away from the axis of the rotating disk 210, and the tooth portion 231 is an external tooth. When the rotating disk 210 drives the gear member 500 to reach the tooth portion 231, the gear member 500 meshes with the external tooth, thereby realizing the self-rotation of the gear member 500.

[0028] It should be noted that the tooth template 230 can also be set on the outside of the turntable 210. In this case, the tooth portion 231 is set on the side of the tooth template 230 close to the axis of the turntable 210, and the tooth portion 231 is set as internal teeth, and the gear part 500 is meshed with the internal teeth, thereby realizing the self-rotation of the gear part 500.

[0029] It is easy to understand that a discharge tray 240 is provided on one side of the turntable 210 away from the tooth template 230 for storing the gear parts 500. At this time, it is only necessary to take the gear parts 500 from the discharge tray 240 and install them on the pins 221, thereby reducing labor intensity and improving work efficiency. Of course, the gear parts 500 can also be taken by a manipulator, and at this time, the gear parts 500 on the discharge tray 240 need to be neatly stacked, thereby improving intelligence.

[0030] Reference Figure 1 , Figure 2 and Figure 6 The grinding mechanism 300 is disposed above the turntable 210 and corresponds to the tooth template 230, and is used to grind the gear part 500 to remove burrs. Specifically, the grinding mechanism 300 includes an abrasive belt 310, which is disposed above the tooth template 230, and is used to grind the gear part 500. By making the grinding mechanism 300 correspond to the tooth template 230, the gear can be ground to remove burrs while simultaneously revolving and rotating. At this time, the deburring of the gear part 500 is more comprehensive, and the product quality is improved; at the same time, since the gear part 500 performs a circular motion during its revolution, the abrasive belt 310 is ground in an arc trajectory, which can not only evenly disperse the wear of the abrasive belt 310 and extend the service life of the abrasive belt 310, but also extend the grinding time of the gear part 500 and improve the deburring quality.

[0031] Specifically, the machine base 100 is provided with a support seat 120, which is located on one side of the turntable 210 and corresponds to the tooth template 230, and the sand belt 310 is arranged on the support seat 120, so as to facilitate the installation of the sand belt 310. Further, the grinding mechanism 300 also includes a sand pressing assembly, which includes a base plate 320 and a grinding back plate 330, the base plate 320 is arranged on the machine base 100, and the grinding back plate 330 is connected to the base plate 320 through an elastic member 340, and the grinding back plate 330 is used to press the lower part of the sand belt 310 toward the gear member 500. Among them, the elastic member 340 is set as a spring. By arranging the elastic member 340 between the base plate 320 and the grinding back plate 330, the grinding force of the sand belt 310 is flexible, so that the sand belt 310 can be prevented from being scratched by burrs that are too thick or too high, the service life of the sand belt 310 is extended, and the deburring quality is improved. It is conceivable that the grinding back plate 330 is provided with a guide rod, which is slidably disposed in the base plate 320, and the spring is sleeved on the guide rod, thereby ensuring the stability of the grinding back plate 330 and further improving the grinding quality.

[0032] In this embodiment, the support seat 120 is provided with an up-down adjustment mechanism 350, and the up-down adjustment mechanism 350 includes a screw rod, which is rotatably arranged on the support seat 120, and the base plate 320 is connected to the screw rod. By providing the up-down adjustment mechanism 350, the position of the grinding back plate 330 can be adjusted, thereby achieving the adjustment of the grinding amount, with a simple structure and easy operation. Of course, the up-down adjustment mechanism 350 can also be implemented by a structure such as a gear and a rack, and this application does not limit this.

[0033] Reference Figures 1 to 5 The discharging mechanism 400 is arranged downstream of the grinding mechanism 300 to output the ground gear part 500. Specifically, the discharging mechanism 400 includes a material ejection assembly and a material ejection track 430. The material ejection assembly includes a mounting seat 410 and an end face cam 420. The mounting seat 410 is slidably arranged on the turntable 210. The mounting seat 410 is provided with a plurality of ejector rods 411 on a circle with the pin shaft 221 as the center. The ejector rods 411 penetrate the turntable 210. The end face cam 420 is arranged below the turntable 210. The material ejection track 430 is arranged above the turntable 210. The material ejection track 430 is adapted to the end face cam 420. The mounting seat 410 can be in contact with the end face cam 420, so that the mounting seat 410 drives the ejector rod 411 to rise to lift the gear part 500 and send it into the material ejection track 430. After the gear part 500 is ground, it continues to rotate with the turntable 210, causing the mounting seat 410 to move along the end face cam 420. At this time, the mounting seat 410 drives the push rod 411 to rise, so as to lift the gear part 500 and send it into the discharge track 430, thereby realizing automatic discharge of the gear part 500.

[0034] The bottom of the mounting seat 410 is provided with an abutment head 412, which is provided with an arc surface, and the abutment head 412 is in contact with the end face cam 420. The arc surface can facilitate the movement of the abutment head 412 along the end face cam 420, thereby improving the stability of the gear member 500.

[0035] Further, a sleeve 223 is provided at the bottom of the pin 221, and the sleeve 223 is inserted under the turntable 210, and the mounting seat 410 is slidably sleeved on the sleeve 223. Specifically, the turntable 210 is provided with a fixed rod 224, and a limited block is provided at the bottom of the fixed rod 224, and the mounting seat 410 is slidably sleeved on the fixed rod 224. By adopting the above structure, it is not only conducive to the installation of the mounting seat 410, but also ensures the sliding of the mounting seat 410, thereby improving the stability and reliability of the work. It is easy to understand that the sleeve 223 is provided with a reset spring 225, and the other end of the reset spring 225 abuts against the mounting seat 410. When the mounting seat 410 moves upward under the action of the end face cam 420, the reset spring 225 is in a compressed state until the mounting seat 410 reaches the highest point of the end face cam 420; when the mounting seat 410 leaves the highest point of the end face cam 420, the mounting seat 410 will move downward under the action of the reset spring 225, thereby realizing the automatic reset of the mounting seat 410.

[0036] It should be noted that the reset spring 225 can also be sleeved outside the sleeve 223, so that the two ends of the reset spring 225 are respectively in contact with the rotating disk 210 and the mounting seat 410, which can also achieve automatic reset of the mounting seat 410.

[0037] It is conceivable that the feed end of the discharge track 430 is provided with an escape opening. When the mounting seat 410 drives the ejector rod 411 to rise to lift the gear member 500 and enter the discharge track 430, the ejector rod 411 is located in the escape opening, thereby ensuring the stability of the discharge of the gear member 500. Further, a pressure strip 440 is provided above the discharge track 430, and a passage for the gear member 500 to pass through is left between the pressure strip 440 and the discharge track 430, thereby preventing the previous gear member 500 from being lifted by the next gear member 500 and affecting the discharge, thereby ensuring the stability of the discharge of the gear member 500.

[0038] The gear part 500 is sleeved on the pin shaft 221, and the gear part 500 is supported by the disc 222, so as to realize the installation of the gear part 500; the turntable 210 drives the gear part 500 to rotate, so as to realize the revolution of the gear part 500; when the turntable 210 drives the gear part 500 to enter the tooth template 230, the gear part 500 meshes with the tooth tooth part 231, so that the gear part 500 rotates around the pin shaft 221, so that the gear part 500 rotates while revolving, and the gear part 500 is ground by the sanding belt 310 at this time, so as to realize the comprehensive grinding of the gear part 500; the turntable 210 drives the gear part 500 to continue to rotate in the direction of the discharge track 430, so that the mounting seat 410 moves along the end face cam 420, and at this time, the mounting seat 410 drives the push rod 411 to rise, so as to lift the gear part 500 and send it into the discharge track 430, so as to realize the automatic discharge of the gear part 500. The deburring device for the gear part 500 according to the embodiment of the present application can achieve comprehensive grinding of the gear part 500 and improve the deburring quality of the gear part 500.

[0039] The deburring device for the gear member 500 described in the embodiment of the present application is provided with a plurality of fixing parts 220 on the circumference of the turntable 210, and the fixing parts 220 include a pin shaft 221 for mounting the gear member 500, so that the gear member 500 can revolve under the action of the turntable 210; a tooth portion 231 coaxial with the turntable 210 is provided on the tooth template 230, and the tooth portion 231 can mesh with the gear member 500 to connect the teeth. When the turntable 210 drives the gear member 500 to revolve to the tooth template 230, the gear member 500 meshes with the tooth portion 231, so that the gear member 500 can rotate around the pin shaft 221 while revolving. At this time, the gear member 500 is ground by the grinding mechanism 300. Grinding, so that the gear part 500 can be fully ground and the deburring quality of the gear part 500 can be improved; by using the turntable 210 to drive the gear part 500 to rotate, the abrasive belt 310 is ground in an arc track, which can not only make the wear of the abrasive belt 310 evenly dispersed and extend the service life of the abrasive belt 310, but also extend the grinding time of the gear part 500 and improve the deburring quality; by contacting and connecting the mounting seat 410 with the end face cam 420, the mounting seat 410 drives the push rod 411 to rise, and the push rod 411 lifts the gear part 500 and sends it into the discharge track 430, thereby realizing automatic discharge of the gear part 500 without manual operation, reducing labor intensity and improving work efficiency.

[0040] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present application.
