[0015] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0016] like Figures 1 to 3 As shown, this gear deburring equipment includes a frame 1, a rotating component 2, an upper air brush component 3, a pressing component 4, and a lower air brush component 5. The frame 1 serves as the overall installation base for this embodiment, and its top is provided with a flat support surface 11. A through hole 12 is opened in the middle of the support surface 11, which provides space for the installation and operation of the rotating component 2.

[0017] like Figure 1 and Figure 2As shown, the rotating assembly 2 is the core component for realizing the workpiece rotation function. It includes a rotating support platform 21, a rotating motor 22, an anti-reverse mounting plate 23, a rotating shaft 24, a motor mounting base 25, a first synchronous pulley 26, a second synchronous pulley 27, a synchronous belt 28, and a rotating positioning block 29. The motor mounting base 25 is fixed to one side of the frame 1 by bolts. The rotating motor 22 is vertically mounted on the motor mounting base 25 with its output shaft facing upward. The first synchronous pulley 26 is connected to the end of the output shaft of the rotating motor 22 by a key. The second synchronous pulley 27 is connected to the lower end of the rotating shaft 24 by a key. The synchronous belt 28 is sleeved between the first synchronous pulley 26 and the second synchronous pulley 27, forming a reliable power transmission structure to ensure that the power of the rotating motor 22 can be stably transmitted to the rotating shaft 24.

[0018] like Figure 1 and Figure 2 As shown, the rotating shaft 24 is vertically arranged, and its upper and lower ends are supported by a first bearing 241 and a second bearing 242, respectively. The outer ring of the first bearing 241 is fixed inside a first bearing housing 243, and the outer ring of the second bearing 242 is fixed inside a second bearing housing 244. Both the first bearing housing 243 and the second bearing housing 244 are fixedly connected to the frame 1 by bolts. This double bearing support structure can effectively reduce the radial runout of the rotating shaft 24 during operation and improve rotational stability. The rotating positioning block 29 is connected to the rotating shaft 24. At the top of shaft 24, anti-reverse mounting plate 23 is connected to the upper end of rotary positioning block 29. Anti-reverse mounting plate 23 is fixed to the upper surface of rotary support platform 21 by bolts. Anti-reverse mounting plate 23 is provided with several positioning holes 231 and fixing holes 232. Fixing holes 232 are used to fix the workpiece to anti-reverse mounting plate 23. At the same time, anti-reverse mounting plate 23 is also provided with protruding limiting protrusion 234 and positioning pin 233. The limiting protrusion 234 and positioning pin 233 cooperate to effectively prevent the workpiece from being installed in the wrong direction and avoid poor processing due to misinstallation.

[0019] like Figures 1 to 3As shown, the rotating support table 21 has an integrally formed extension plate 211 on its edge. The pressure assembly 4 is installed on the upper end of the extension plate 211. The pressure assembly 4 is used to clamp and fix the workpiece during processing. The pressure assembly 4 includes a pressure fixing body 41, a pressure cylinder 42, a rotating body 43, a pressure head 44, a connecting shaft 45, and a pressure mounting plate 46. The pressure fixing body 41 is vertically fixed on the upper end of the extension plate 211. The pressure cylinder 42 is vertically mounted downward on the pressure fixing body 41. The cylinder push rod 421 of the pressure cylinder 42 is set downward, and the end of the cylinder push rod 421 is connected to the top end of the connecting shaft 45. The rotating body 43... The three sets are installed in the middle of the connecting shaft 45, and the rotating body 43 and the pressing body 41 are connected by bearings, which can rotate flexibly around the horizontal axis. The pressing head 44 is fixed at the bottom of the connecting shaft 45. The pressing head 44 is made of elastic material to avoid scratching the surface of the workpiece during the pressing process. When the cylinder push rod 421 of the pressing cylinder 42 extends, it can push the connecting shaft 45 to drive the pressing head 44 to move downward until the pressing head 44 contacts the upper surface of the workpiece and applies a certain pressure to achieve workpiece pressing. When it is necessary to release the workpiece, the cylinder push rod 421 retracts and drives the pressing head 44 to return to the starting position. The operation is convenient and the pressing force is stable and controllable.

[0020] To elaborate further, such as Figure 1 As shown, the upper air brush assembly 3 and the lower air brush assembly 5 are used to brush the upper and lower surfaces of the workpiece, respectively. The upper air brush assembly 3 includes an upper air brush chuck 31, which is fixed above the frame 1 by a bracket and located above the rotating assembly 2. The upper air brush chuck 31 can hold the brush tool and can move up and down and rotate through an external drive mechanism to clean or polish the upper surface of the workpiece from all directions. The lower air brush assembly 5 includes a lower air brush chuck 51, which is fixed on the frame 1. Corresponding to the upper air brush chuck 31, the lower air brush chuck 51 can also hold the brush tool. During the rotation of the workpiece, the lower air brush assembly 5 can simultaneously process the lower surface of the workpiece, realizing simultaneous processing of the upper and lower surfaces and further improving work efficiency.
