For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0045] The technical solutions of the present application will be described in detail below in combination with the drawings.

[0046] The polishing unit 1 provided by the present application comprises a first translation member 11 fixed at a certain position, a first driving member 12 and a polishing member 13, wherein the first translation member 11 is connected with the first driving member 12 and can drive the first driving member 12 to move back and forth along a fixed path, and the first driving member 12 is connected with the polishing member 13, so that when the first driving member 12 moves, the polishing member 13 can also move synchronously.

[0047] The polishing member 13 comprises a limiting piece 131 and a polishing cutter head, and the polishing cutter head is in transmission connection with the first driving member 12 and can rotate under the driving of the first driving member 12.

[0048] When the polishing member 13 moves towards the polishing part 2 under the driving of the first translation member 11, the limiting piece 131 can be connected with the polishing part 2, and the polishing cutter head can be connected with the polishing area of the polishing part 2.

[0049] It should be noted that the fixed path is a path pointing to the position of the polishing part 2, when the polishing head is driven to reciprocate along the fixed path, the polishing head can approach or move away from the polishing part 2, and at this time the polishing head points to the area where the burr on the polishing part 2 is located.

[0050] The structure of the above-mentioned polishing part 2 is as shown in Figure 1 The part is a POT product, and the middle part is provided with a metal core (which can be an iron core), and the outer part is made of plastic material. Two areas in the polishing part 2 will form burrs, as shown by the arrows in Figure 1 The polishing unit 1 is used for burr removal of the polishing part 2 as shown in Figure 1 .

[0051] Embodiment 1:

[0052] The embodiment as shown in Figure 2 provides a polishing unit 1, which comprises a first translation member 11, a first driving member 12 and a polishing member 13, wherein the first translation member 11 is connected with the first driving member 12 and drives the first driving assembly to reciprocate along a fixed path; the first driving member 12 is connected with the polishing member 13 and the polishing part 2 is located below the polishing member 13, when the first driving member 12 moves, the polishing member 13 can also move synchronously and approach or move away from the above-mentioned polishing part 2.

[0053] The polishing member 13 comprises a limiting piece 131 and a polishing head, wherein the limiting piece 131 can be connected with the polishing part 2 and play a certain limiting role, at this time the polishing head can be directed to the polishing area of the polishing part 2 and polish the polishing area, thereby effectively removing the burr. Compared with the traditional manual burr removal method, the technical solution provided by the embodiment has a faster removal speed.

[0054] Specifically, the above-mentioned polishing member 13 further comprises a tool rest 132 for fixing the polishing head, and the tool rest 132 is connected with the first driving member 12. Therefore, when the first driving member 12 is started, the above-mentioned tool rest 132 can rotate under the driving of the first driving member 12, at this time the polishing head fixedly arranged on the tool rest 132 can rotate and realize the scraping of the burr.

[0055] As an optional embodiment, the polishing head comprises a first head 133 and a second head 134 with different blade directions, the blade of the first head 133 is directed to one side parallel to the tool rest 132 or is deflected relative to the tool rest, and the blade of the second head 134 is directed to one side away from the tool rest 132, as shown in Figure 3 .

[0056] Specifically, when the cutting edge of the first cutting head 133 is deflected relative to the holder 132, the cutting edge is directed towards the side close to the grinding part 2 to facilitate the removal of burrs formed on the grinding part 2. In this embodiment, the first cutting head 133 can be deflected downwards by 6-8° relative to the holder 132.

[0057] It should be noted that, when the area where the burrs to be removed is located has a height difference, the height of the cutting edges of the first cutting head 133 and the second cutting head 134 also has a certain difference.

[0058] In actual arrangement, the shape of the holder 132 and the shape of the cutting head can be adjusted adaptively according to the height and width of the area where the burrs are formed on the grinding part 2. The shape and arrangement position of the first cutting head 133 and the second cutting head 134 given in this embodiment are only examples and do not limit the protection scope of this embodiment.

[0059] In addition, it should be noted that, in order to ensure that the grinding member 13 can rotate at a high speed stably, it is necessary to ensure that the grinding cutting heads are arranged symmetrically about the center.

[0060] In order to better realize the fixation and limiting of the grinding part 2, as an optional implementation, the limiting member 131 has a hollow columnar structure, and when the grinding part 2 is connected with the limiting member 131, part of the grinding part 2 can be inserted into the limiting member 131.

[0061] The limiting member 131 only needs to be able to realize the limiting and fixation of the grinding part 2, and the rest is not limited. In this embodiment, the limiting member 131 can be connected with the first driving member 12 and rotate under the driving of the first driving member 12, or can not be connected with the first driving member 12.

[0062] When the grinding unit 1 is used, the structural relationship thereof with the grinding part 2 is as shown in Figure 4 At this time, the limiting member 131 can be connected with the metal core part of the grinding part 2, and the grinding cutting head is just located at the area where the burrs are formed on the grinding part 2. When the first driving member 12 is started, the grinding cutting head rotates and can simultaneously remove the burrs formed on the two different areas on the inner side of the grinding part 2. When the grinding part 2 is processed, the first driving member 12 is stopped, at this time, the first translation member 11 drives the first driving member 12 and the grinding cutting head to move upwards and away from the grinding part 2. Then, the grinding part 2 processed is removed and replaced with an unground grinding part 2, the first translation member 11 is started to move the grinding cutting head downwards to the appropriate position, and then the above process is repeated.

[0063] It should be noted that, when the grinding unit 1 removes the burrs of the grinding part 2, the grinding part 2 should be fixed.

[0064] The first translation member 11 is not limited in the specific structure, as long as it can realize linear displacement. For example, the first translation member 11 can be a ball screw, or a device including a slide rail 612, a slide block and a driving member. The slide rail 612 is arranged along the vertical direction, and the slide block can move up and down along the slide rail 612 under the driving of the driving member. The driving member can be a motor, a hydraulic pump or other devices capable of realizing linear displacement.

[0065] Embodiment 2

[0066] The present application also provides a burr removing device, which comprises the polishing unit 1, and further comprises a conveying unit 3 and a brush unit 4.

[0067] Specifically, the polishing unit 1 and the brush unit 4 are both distributed around the conveying unit 3 and sequentially distributed along the conveying direction of the conveying unit 3. The polishing part 2 to be processed sequentially passes through the polishing unit 1 and the brush unit 4. The brush unit 4 can brush off the residual burrs on the polishing part 2 which are not removed by the polishing unit 1, so as to achieve the effect of completely removing the burrs.

[0068] The structure of the brush unit 4 is shown in Figure 7 The brush unit 4 comprises a second translation member 41, a second driving member 42 and a brush member 43. The second driving member 42 is connected with the brush member 43 and can drive the brush member 43 to rotate. The second translation member 41 is connected with the second driving member 42 and can drive the second driving member 42 to move back and forth along a fixed path.

[0069] It should be noted that, in the present embodiment, the moving path of the second translation member 41 is parallel to the moving path of the first translation member 11. That is, the second translation member 41 can drive the second driving member 42 to move up and down along a fixed path.

[0070] In addition, the structure of the second translation member 41 is basically the same as that of the first translation member 11.

[0071] When the brush unit 4 is started, the second translation member 41 can drive the second driving member 42 and the brush member 43 to move synchronously until the brush member 43 is inserted into the polishing part 2. Then, the second driving member 42 is started and drives the brush member 43 to rotate, so that the brush member 43 can brush off the residual burrs on the part by rotating. Then, the second driving member 42 is stopped, and the second translation member 41 is started and drives the second driving member 42 and the brush member 43 to move upwards until the brush member 43 is extracted from the polishing part 2.

[0072] With the conveying of the conveying unit 3, the brush unit 4 can sequentially perform burr removal processing on different polishing parts 2.

[0073] After the polishing unit 1 and the brush unit 4 are processed, the burrs in the polishing part 2 have been removed, but at this time the burrs scraped off are still left inside the part, which will affect the subsequent processing of the polishing part 2. In order to remove the above-mentioned residual burr debris, as an optional embodiment, the device further comprises a cleaning unit 5 located on the side of the conveying unit 3. Figure 8 As shown, the polishing part 2 processed by the brush unit 4 can be conveyed to the cleaning unit 5. The cleaning unit 5 can process the debris such as burrs left inside the polishing part 2, effectively solving the problem of debris remaining.

[0074] Specifically, the cleaning unit 5 comprises a third translation member 51 and a suction member 52, and the suction member 52 can be driven by the third translation member 51 to approach or move away from the polishing part 2; when part of the suction member 52 extends into the polishing part 2, the suction member 52 can suck the debris accumulated in the polishing part 2.

[0075] The structure of the above-mentioned third translation member 51 is basically the same as that of the first translation member 11. At the same time, in this embodiment, the moving path of the third translation member 51 is parallel to the moving path of the first translation member 11. That is, the third translation member 51 can drive part of the structure of the suction member 52 to move up and down along the fixed path.

[0076] Specifically, the above-mentioned suction member 52 comprises a dust collection gun, a conveying pipe and a storage cavity, the conveying pipe communicates the dust collection gun and the storage cavity, and the dust collection gun can be driven by the third lifting member to approach or move away from the polishing part 2. When the dust collection gun approaches the polishing part 2 and is in the starting state, it can realize the suction of the debris in the polishing part 2, and the suctioned debris can be conveyed to the storage cavity through the conveying pipe for temporary storage.

[0077] The conveying pipe should be a soft pipe structure. The structure of the above-mentioned conveying pipe and storage cavity is not drawn.

[0078] In order to take the polishing part 2 processed by the above-mentioned units from the conveying unit 3, as an optional embodiment, the device further comprises a discharging unit 6 located on the side of the conveying unit 3.

[0079] Specifically, the discharging unit 6 comprises a grabbing member 61, a fourth translation member 62 and a fifth translation member 63, and the grabbing member 61 is connected with the fourth translation member 62 and the fifth translation member 63; the fourth translation member 62 can drive the grabbing member 61 to move along the first path, and the fifth translation member 63 can drive the grabbing member 61 to move along the second path, and the first path and the second path are perpendicular to each other.

[0080] In the embodiment, as shown in Figure 9 The fourth translation member 62 is directly connected with the grabbing member 61 and can drive the grabbing member 61 to move up and down along the vertical direction. The fifth translation member 63 is connected with the fourth translation member 62 and can drive the fourth translation member 62 to move horizontally. Since the grabbing member 61 is fixedly connected with the fourth translation member 62, the grabbing member 61 can also move horizontally synchronously.

[0081] It should be noted that the fifth translation member 63 can drive the fourth translation member 62 to move towards or away from the conveying unit 3. When the fifth translation member 63 moves away from the conveying unit 3, the grabbing member 61 can also move away from the conveying unit 3 and achieve the unloading.

[0082] In the embodiment, the structures of the fourth translation member 62 and the fifth translation member 63 are prior art, which will not be described herein.

[0083] Specifically, a conveying belt is arranged below the moving path of the first translation member 11. The grabbing member 61 can grab the finished polishing part 2 and place it on the conveying belt. The finished polishing part 2 can be conveyed to the next processing station or packaged for processing, etc. through the conveying belt.

[0084] The structure of the grabbing member 61 will be described below.

[0085] The grabbing member 61 includes a fourth driving member 611, a sliding rail 612, and two clamping jaws 613 symmetrically arranged on the sliding rail 612. The two clamping jaws 613 can move towards or away from each other under the drive of the fourth driving member 611.

[0086] When the clamping jaws 613 move to the appropriate height and move towards each other, the clamping jaws 613 can be connected with the polishing part 2 and achieve clamping of the polishing part 2, so as to take the polishing part 2 off the conveying unit 3. When the clamping jaws 613 move to the appropriate position and move away from each other, the polishing part 2 is released.
