[0037] Embodiment 1:

[0038] A shaft deburring device, such as Figures 1 to 4 As shown, the base 100, the guide rail mechanism 200 and the grinding mechanism 300 are included, and the guide rail mechanism 200 and the grinding mechanism 300 are installed on the top of the base 100. The guide rail mechanism 200 includes a guide rail bracket 210 and a guide rail 220, and the guide rail 220 is fixed on the guide rail bracket 210 to transmit and guide the shaft 500. A notch 224 is provided in the middle of the guide rail 220, and two notches 224 are provided, and the two notches 224 are respectively located on both sides of the guide rail 220. The grinding mechanism 300 includes a brush wheel 310 with bristles on the circumference, a tendon wheel 320 with a tendon layer on the circumference, and a driving component. The driving component is respectively connected to the brush wheel 310 and the tendon wheel 320 to drive the brush wheel 310 and the tendon wheel 320 to rotate synchronously. The outer edges of the brush wheel 310 and the tendon wheel 320 extend into two recesses 224 from both sides of the guide rail 220 respectively, so as to grind burrs on the shaft 500 passing through the recess 224.

[0039] The utility model reserves two notches 224 on the guide rail 220 for the brush wheel 310 and the tendon wheel 320 to extend into, and drives the brush wheel 310 and the tendon wheel 320 to rotate at the same time through the driving component, so that when the shaft 500 needs to be deburred, the driving component is turned on, and the driving component drives the brush wheel 310 and the tendon wheel 320 to rotate synchronously. It is only necessary to place the shaft 500 on the guide rail 220 and push it from one end of the guide rail 220 to the other end of the guide rail 220. The outer surface of the shaft 500 passing through the notch 224 contacts the brush wheel 310 and the tendon wheel 320 at the same time, and the tendon wheel 320 drives the shaft 500 to rotate synchronously. 00 rotates around the central axis, and the rotating brush wheel 310 removes burrs on the circumference of the shaft 500. After the shaft 500 is transported on the guide rail 220, the burr removal is completed. During the entire deburring process, the shaft 500 driven by the tendon wheel 320 to rotate makes it unnecessary for the grinding mechanism 300 to rotate or translate around the shaft 500, so that the burrs on the circumference of the shaft 500 can be removed, making the shaft deburring device simple in structure. The movable feature of the shaft 500 makes the replacement operation of the shaft 500 simple and convenient, and the staff can quickly replace the shaft 500, thereby improving the processing efficiency of the shaft 500.

[0040] like Figure 2 and Figure 3 As shown, in this embodiment, the guide rail 220 is a horizontally extending support plate 221, and both sides of the support plate 221 are bent upward to form a V-shaped groove 222 for transmitting the shaft member 500 above the support plate 221. The setting of the V-shaped groove 222 allows the support plate 221 to limit the shaft members 500 of various outer diameters in the horizontal direction through the inner wall of the V-shaped groove 222, preventing the shaft member 500 from rolling on the guide rail 220, thereby ensuring that the outer surface of the shaft member 500 is always in contact with the tendon wheel 320 and the brush wheel 310, so that the shaft member 500 can rotate stably to remove burrs. Preferably, the bottom surface of the V-shaped groove 222 is an arc surface 223, which enhances the strength of the guide rail 220 at the bend and prevents the guide rail 220 from breaking at the bend.

[0041] The guide rail mechanism 200 in this embodiment also includes a clamping assembly 230, which includes a pressure rod 231 and a connecting rod 232. The pressure rod 231 is horizontally arranged above the V-shaped groove 222. The central axis of the pressure rod 231 is parallel to the transmission direction of the guide rail 220. The two ends of the pressure rod 231 are respectively fixed to the guide rail bracket 210 through the connecting rod 232. When the shaft 500 is transported in the V-shaped groove 222, the pressure rod 231 is located above the shaft 500 to limit the shaft 500 in the vertical direction to prevent the shaft 500 from moving up and down, thereby ensuring the stable transmission of the shaft 500 in the V-shaped groove 222, and then ensuring the stable grinding of the shaft 500 to remove burrs. Figure 4As shown, the bottom end of the connecting rod 232 is fixed to the top of the guide rail bracket 210, and the top end of the connecting rod 232 is horizontally bent above the guide rail 220 to form an extension end 2321 located above the pressure rod 231. An adjusting screw 233 is connected between the pressure rod 231 and the extension end 2321. The adjusting screw 233 can not only fix the pressure rod 231, but also adjust the gap height between the pressure rod 231 and the extension end 2321, that is, adjust the height of the pressure rod 231, so that the pressure rod 231 can limit the shaft 500 with different outer diameters, and has a wider range of applications.

[0042] In this embodiment, the driving assembly includes a first driving motor 330 and a second driving motor 340, the first driving motor 330 and the second driving motor 340 are located on both sides of the guide rail 220, the output shaft of the first driving motor 330 is connected to the brush wheel 310 to drive the brush wheel 310 to rotate, and the output shaft of the second driving motor 340 is connected to the tendon wheel 320 to drive the tendon wheel 320 to rotate, and the structure is simple and reliable. The first driving motor 330 and the second driving motor 340 are respectively fixed to the base 100 through the mounting bracket 400, and the mounting bracket 400 raises the height of the first driving motor 330 and the second driving motor 340, so that the height of the brush wheel 310 and the tendon wheel 320 is raised at the same time, avoiding the base 100 from preventing the brush wheel 310 and the tendon wheel 320 from rotating, ensuring the smooth rotation of the brush wheel 310 and the tendon wheel 320, and also avoiding contact wear between the rotating brush wheel 310 and the tendon wheel 320 and the base 100.

[0043] Embodiment 2:

[0044] The difference between this embodiment and embodiment one is that, in this embodiment, the driving assembly includes a driving motor and a gear box, and the gear box is respectively connected to the brush wheel, the tendon wheel and the driving motor, and the driving motor drives the brush wheel and the tendon wheel to rotate synchronously through the gear box. The setting of the gear box enables a single driving motor to drive the brush wheel and the tendon wheel to rotate at the same time, thereby simplifying the circuit structure of the deburring device and reducing production costs.
