[0002] Removing burrs on stamping parts is one of the most important post-process projects after stamping production. There are various burr removal processes and methods, such as machine tool cutting, abrasive belt grinding, brush, roller grinding, vibration grinding and sand blasting, and the advantages and disadvantages of the processes and methods are different, but they all have a common characteristic, that is, a little burr residue in one direction is pressed and attached to the side of the workpiece during the burr removal process, especially in the machining mode (such as machine tool cutting and abrasive belt grinding).

[0031] Reference Figures 1 to 6The embodiment of the application provides a deburring device for gear machining, which comprises a base 100, a conveying mechanism 200, a grinding mechanism 300 and a discharging mechanism 400.

[0032] With reference to Figures 1 to 4 The conveying mechanism 200 is used for conveying the gear part 500. Specifically, the conveying mechanism 200 comprises a rotating disc 210, a fixing part 220 and a tooth template 230. The rotating disc 210 is rotationally arranged on the base 100. The fixing part 220 is arranged in plurality and circumferentially arranged on the rotating disc 210. The fixing part 220 comprises a pin shaft 221 and a mounting base 410. The pin shaft 221 is arranged on the rotating disc 210 and is used for mounting the gear part 500. The mounting base 410 is slidably sleeved on the pin shaft 221 and is located below the rotating disc 210. The mounting base 410 is circumferentially arranged with a plurality of top rods 411 with the pin shaft 221 as the center. The top rods 411 are arranged through the rotating disc 210. The tooth template 230 is arranged on one side of the fixing part 220. The tooth template 230 is provided with a tooth part 231. The tooth part 231 is coaxial with the rotating disc 210. The tooth part 231 can be engaged with the gear part 500, so that the gear part 500 rotates around the pin shaft 221. The gear part 500 is mounted on the pin shaft 221. The rotating disc 210 rotates to drive the gear part 500 to rotate, so that the gear part 500 rotates around the pin shaft 221. When the rotating disc 210 drives the gear part 500 to enter the tooth template 230, the tooth part 231 is engaged with the gear part 500, so that the gear part 500 rotates around the pin shaft 221 while rotating around the pin shaft 221.

[0033] Further, the fixing part 220 further comprises a disc 222. The disc 222 is located above the rotating disc 210 and is used for supporting the gear part 500. The top rods 411 are arranged through the disc 222. The disc 222 supports the gear part 500, so that the contact area between the fixing part 220 and the gear part 500 is increased, thereby ensuring the stability of the gear part 500. The disc 222 is provided with a concave ring, so that the friction between the disc 222 and the gear part 500 is reduced, thereby improving the product quality.

[0034] In some embodiments of the application, the base 100 is provided with a fixing disc 110 above the rotating disc 210. The tooth template 230 is arranged on the fixing disc 110. At this time, the tooth part 231 is arranged on the side of the tooth template 230 away from the axis of the rotating disc 210. The tooth part 231 is an external tooth. When the rotating disc 210 drives the gear part 500 to reach the tooth part 231, the gear part 500 is engaged with the external tooth, so that the gear part 500 rotates around the pin shaft 221.

[0035] It should be noted that the tooth template 230 can also be arranged on the outside of the rotating disc 210. At this time, the tooth part 231 is arranged on the side of the tooth template 230 close to the axis of the rotating disc 210. The tooth part 231 is an internal tooth. The gear part 500 is engaged with the internal tooth, so that the gear part 500 rotates around the pin shaft 221.

[0036] It is easy to understand that the side of the rotating disc 210 away from the tooth template 230 is provided with a feeding tray 240 for storing the gear piece 500, at this time only the gear piece 500 needs to be taken from the feeding tray 240 and installed on the pin shaft 221, which reduces the labor intensity and improves the work efficiency. Of course, the taking of the gear piece 500 can also be carried out by a mechanical hand, at this time the gear pieces 500 on the feeding tray 240 need to be neatly stacked, thereby improving the intelligence.

[0037] Referring to Figure 1 , Figure 2 and Figure 6 , the grinding mechanism 300 is arranged above the rotating disc 210 and corresponds to the tooth template 230, and is used for grinding the gear piece 500 to deburr. Specifically, the grinding mechanism 300 includes a sand belt 310, the sand belt 310 is arranged above the tooth template 230, and the sand belt 310 is used for grinding the gear piece 500. By corresponding the grinding mechanism 300 to the tooth template 230, the gear can be ground to deburr while revolving and rotating at the same time, at this time the deburring of the gear piece 500 is more comprehensive, improving the product quality; at the same time, since the gear piece 500 performs a circular motion when revolving, the sand belt 310 performs an arc trajectory grinding, which not only can make the wear of the sand belt 310 evenly dispersed, prolonging the service life of the sand belt 310, but also can prolong the grinding time of the gear piece 500, improving the deburring quality.

[0038] Specifically, the machine base 100 is provided with a support seat 120, the support seat 120 is located on one side of the rotating disc 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 further includes a sand pressing assembly, the sand pressing assembly 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 with the base plate 320 through an elastic piece 340, and the grinding back plate 330 is used for pressing the lower part of the sand belt 310 to the gear piece 500. Wherein, the elastic piece 340 is arranged as a spring. By arranging the elastic piece 340 between the base plate 320 and the grinding back plate 330, the grinding force of the sand belt 310 has flexibility, so as to avoid the sand belt 310 being scratched by the too thick and too high burr, prolonging the service life of the sand belt 310 and improving the deburring quality. It is conceivable that the grinding back plate 330 is provided with a guide rod, the guide rod is slidably arranged in the base plate 320, and the spring is sleeved on the guide rod, so as to ensure the stability of the grinding back plate 330, further improving the grinding quality.

[0039] In the embodiment, the support base 120 is provided with an up-down adjusting mechanism 350, the up-down adjusting mechanism 350 comprises a screw rod, the screw rod is rotationally arranged on the support base 120, and the base plate 320 is connected with the screw rod. By arranging the up-down adjusting mechanism 350, the position of the grinding back plate 330 can be adjusted, so that the grinding amount is adjusted, and the structure is simple and the operation is simple. Of course, the up-down adjusting mechanism 350 can also be realized by using a gear and a rack cooperation structure, and the application does not limit this.

[0040] With reference to Figures 1 to 5 The discharging mechanism 400 is arranged downstream of the grinding mechanism 300, and is used for outputting the ground gear piece 500. Specifically, the discharging mechanism 400 comprises a top-up assembly and a discharging track 430, the top-up assembly comprises a mounting seat 410 and an end face cam 420, the mounting seat 410 is slidingly arranged on the turntable 210, the mounting seat 410 is circumferentially arranged with a plurality of top rods 411 with the pin shaft 221 as the center, the top rods 411 are arranged through the turntable 210, the end face cam 420 is arranged below the turntable 210, the discharging track 430 is arranged above the turntable 210, the discharging track 430 is matched with 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 top rods 411 to rise to lift and feed the gear piece 500 into the discharging track 430. After the gear piece 500 is ground, the turntable 210 continues to rotate, the mounting seat 410 moves along the end face cam 420, at this time, the mounting seat 410 drives the top rods 411 to rise to lift and feed the gear piece 500 into the discharging track 430, so that the automatic discharging of the gear piece 500 is realized.

[0041] The bottom of the mounting seat 410 is provided with an abutting head 412, the abutting head 412 is provided with an arc surface, and the abutting head 412 is in contact with the end face cam 420. By arranging the arc surface, the abutting head 412 can move along the end face cam 420, so that the stability of the gear piece 500 is improved.

[0042] Further, the bottom of the pin shaft 221 is provided with a sleeve 223, the sleeve 223 is arranged below the rotating disc 210, and the mounting seat 410 is sleeved on the sleeve 223. Specifically, the rotating disc 210 is provided with a fixing rod 224, the bottom of the fixing rod 224 is provided with a limiting block, and the mounting seat 410 is sleeved on the fixing rod 224. By adopting the above structure, the mounting of the mounting seat 410 is facilitated, and the sliding of the mounting seat 410 is ensured, thereby improving the stability and reliability of work. It can be easily understood that the sleeve 223 is provided with a reset spring 225, 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.

[0043] 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 abut against the rotating disc 210 and the mounting seat 410 respectively, and the automatic reset of the mounting seat 410 can also be realized.

[0044] It can be conceived that the feeding end of the discharging track 430 is provided with a avoiding opening. When the mounting seat 410 drives the top rod 411 to rise to lift the gear member 500 and enter the discharging track 430, the top rod 411 is located in the avoiding opening, thereby ensuring the stability of the discharging of the gear member 500. Further, the upper portion of the discharging track 430 is provided with a pressing strip 440, and a channel for the gear member 500 to pass through is left between the pressing strip 440 and the discharging track 430, thereby preventing the front gear member 500 from being lifted by the rear gear member 500 and affecting the discharging, and ensuring the stability of the discharging of the gear member 500.

[0045] The gear part 500 is sleeved on the pin shaft 221, and the gear part 500 is supported by the disc 222, so that the gear part 500 is installed; the rotating disc 210 drives the gear part 500 to rotate, so that the gear part 500 revolves; when the rotating disc 210 drives the gear part 500 to enter the toothed template 230, the gear part 500 is engaged with the toothed part 231, so that the gear part 500 rotates around the pin shaft 221, so that the gear part 500 revolves and also rotates at the same time; at this time, the gear part 500 is ground by the abrasive belt 310, so that the gear part 500 is fully ground; the rotating disc 210 drives the gear part 500 to continue to rotate towards the discharging track 430, so that the mounting seat 410 moves along the end face cam 420; at this time, the mounting seat 410 drives the ejector rod 411 to rise, so that the gear part 500 is lifted and sent into the discharging track 430, so that the gear part 500 is automatically discharged. The gear part 500 deburring device can fully grind the gear part 500, and improves the deburring quality of the gear part 500.
