[0057] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0058] like Figure 1 and Figure 2 , Figure 3 , Figure 4 As shown, the present invention provides a double-sided polishing device for a cutting tool, including a bottom plate 11, a top plate 12, a positioning component 2, a polishing wheel 43 and other structures.

[0059] The bottom plate 11 and the top plate 12 are arranged in sequence from top to bottom, have corresponding positions, and rotate synchronously. The bottom plate 11 and the top plate 12 have the same size.

[0060] A plurality of bottom grooves 13 are formed on the bottom plate 11 , and a plurality of top grooves 14 are formed on the top plate 12 . The bottom grooves 13 and the top grooves 14 correspond to each other in an upper and lower direction, and the positioning components 2 are distributed in each of the bottom grooves 13 and the top grooves 14 .

[0061] The polishing wheel 43 can move between the bottom plate 11 and the top plate 12 to grind the upper end surface of the cutting tool 6 on the bottom groove 13 and the lower end surface of the cutting tool 6 on the top groove 14 .

[0062] The end of the positioning component 2 can extend to the inner hole of the cutting tool 6, and can be driven from a contracted state to an extended state to be supported on the inner hole wall of the cutting tool 6 to fix the cutting tool 6.

[0063] Among them, Figure 3 As shown, a lifting bolt 312 is provided in the bottom groove 13 , and the lifting bolt 312 is supported on the bottom of the cutting tool 6 , and can lift the cutting tool 6 from the bottom groove 13 to the top groove 14 .

[0064] In the present invention, a bottom plate 11 and a top plate 12 are respectively provided at the upper and lower positions. First, the cutting tool 6 is placed in the bottom plate 11. The cutting tool 6 is fixed to the inner hole wall in the horizontal direction by the positioning component 2, which will not cause any stopping effect on the polishing plane of the cutting tool 6. The polishing wheel 43 is used to polish the upper surface of the cutting tool 6. After the polishing is completed, the cutting tool 6 is lifted from the bottom plate to the top plate 12 by the lifting bolt 312. The cutting tool 6 is fixed again by the positioning component 2. At this time, the polishing wheel 43 is below the cutting tool 6, and the lower surface of the cutting tool 6 can be polished. During the whole process, on the one hand, the cutting tool 6 is fixed from the inner hole wall to ensure the comprehensiveness of the polishing. On the other hand, the cutting tool 6 is automatically driven to different positions to realize double-sided polishing of the cutting tool, thereby improving the polishing efficiency.

[0065] In the present invention, in order to avoid the polishing process being stopped by the positioning component 2, it is necessary to ensure that when the cutting tool 6 is in the bottom groove 13, the upper surface of the cutting tool 6 is higher than the upper end of the positioning component 2, and when the cutting tool 6 is in the top groove 14, the lower surface of the cutting tool 6 is lower than the lower end of the positioning component 2. This can ensure that: when the upper surface of the cutting tool 6 is polished, the upper end of the positioning component 2 will not exceed the position of the upper surface of the cutting tool 6, and when the lower surface of the cutting tool 6 is polished, the lower end of the positioning component 2 will not exceed the position of the lower surface of the cutting tool 6.

[0066] In order to limit the outer wall of the cutting tool 6, the present invention makes the following design: the inner diameter of the bottom groove 13 and the top groove 14 is consistent with the outer diameter of the cutting tool 6. When the cutting tool 6 is placed in the bottom groove 13 and the top groove 14, the outer periphery of the cutting tool 6 contacts the inner peripheral wall of the bottom groove 13 and the top groove 14.

[0067] The driving direction, time and speed of the top plate 12 and the bottom plate 11 are consistent, and they rotate synchronously, and both the top plate 12 and the bottom plate 11 rotate intermittently.

[0068] Assume that three bottom grooves 13 are provided on the bottom plate 11 and three top grooves 14 are provided on the top plate 12, one of the bottom grooves 13 is used for loading, and the cutting tool 6 on one of the bottom grooves 13 is used for polishing. At this polishing position, the cutting tool 6 on the bottom groove 13 is transferred to the top groove 14, and the cutting tool 6 on the top groove 14 is unloaded at the position of the third top groove 14.

[0069] In this embodiment, the top plate 12 and the bottom plate 11 rotate synchronously and stop synchronously. At the loading station, the cutting tool 6 is loaded on the positioning component 2 on the bottom plate 11. At the polishing station, the upper end surface of the cutting tool 6 is first polished, and then the lower end surface of the cutting tool 6 is polished on the top groove 14.

[0070] The present invention uses a positioning component 2 to fix the inner hole of the cutting tool 6 from the inside. The positioning component 2 in the present invention adopts the following preferred embodiments, such as Figure 5 , Figure 6 As shown, the positioning component 2 includes a rotating round seat 211 disposed in the bottom groove 13 and the top groove 14, a fixed seat 212 disposed on the rotating round seat 211, a rotating shaft 213 rotatably disposed in the fixed seat 212, and an arc-shaped abutment plate 214 connected to the rotating shaft 213;

[0071] The rotating round seat 211 is arranged at the center of the bottom groove 13 and the top groove 14, and the outer diameter of the rotating round seat 211 is larger than the inner diameter of the inner hole of the cutting tool 6;

[0072] The fixing seats 212 are arranged in a circular array, and the arc-shaped abutment plates 214 are rotatably mounted on the fixing seats 212 via the rotating shaft 213;

[0073] The arc-shaped abutment plate 214 is movably abutted against the inner hole wall of the cutting tool 6 .

[0074] In this embodiment, the arc-shaped support plate 214 can be driven to rotate under the rotation of the rotating shaft 213. In this embodiment, four arc-shaped support plates 214 are set. In the initial state, the arc-shaped support plate 214 is in a contracted state (a state of tilting inward and approaching). Under the rotation action of the rotating shaft 213, the arc-shaped support plate 214 rotates outward to an extended state (gradually tending to a vertical state), and rotates to abut against the inner hole wall of the cutting tool 6. At this time, the positioning component 2 realizes the positioning of the cutting tool 6.

[0075] In order to drive the rotating shaft 213 to rotate so that the arc-shaped abutment plate 214 rotates to position the cutting tool 6, the present invention makes the following design, such as Figure 6 and Figure 7 As shown, the outer peripheral side of the rotating shaft 213 is provided with shaft teeth 221, and a gear translation bolt 222 is meshedly provided below the shaft teeth 221. A groove is provided at the center position of the rotating round seat 211, and a rotating inner ring seat 223 is rotatably installed in the groove. The end of the gear translation bolt 222 is rotatably connected to a rotating bolt 224;

[0076] The end of the rotating bolt 224 is rotatably connected to the rotating inner ring seat 223 , and a driving motor 225 is connected to the center of the bottom of the rotating inner ring seat 223 .

[0077] The rotating round seat 211 is provided with a translation slot 226 for the gear translation bolt 222 to translate, and the translation slot 226 is arranged along the radial direction of the rotating round seat 211 .

[0078] The driving motor 225 drives the rotating inner ring seat 223 to rotate clockwise, and the rotating inner ring seat 223 drives one end of the rotating bolt 224 to rotate, and the other end of the rotating bolt 24 is dragged out to the side of the rotating inner ring seat 223, thereby driving the gear translation bolt 222 to translate inward (slide along the translation groove 226). Under the translation action of the gear translation bolt 222, the shaft tooth 221 rotates to drive the rotating shaft 213 to rotate, thereby driving the arc-shaped support plate 214 to rotate outward to position the cutting tool 6. After the cutting tool 6 is positioned, it is affected by the reverse limiting effect of the cutting tool 6. The driving motor 225 continues to rotate and cannot drive the arc-shaped support plate 214 to continue to rotate through the above-mentioned transmission structure. Therefore, under the drive of the transmission structure, it directly drives the whole to rotate around the central axis, thereby driving the rotating round seat 211 to rotate. The rotation of the rotating round seat 211 can directly drive the arc-shaped support plate 214 to rotate around the central axis, thereby driving the cutting tool 6 to rotate, and cooperate with the work of the double-sided polishing mechanism 4 to complete the comprehensive polishing of the upper end surface of the cutting tool 6.

[0079] In the above embodiments, the polishing work is achieved by the rotation and fixation of the cutting tool 6 itself.

[0080] In order to ensure that the rotation of the driving motor 225 in the initial state does not directly drive the rotation of the rotating round seat 211, but only drives the rotation of the rotating inner ring seat 223, it is necessary to make the friction between the rotating round seat 211 and the bottom groove 13 and the top groove 14 much greater than the friction between the rotating round seat 211 and the rotating inner ring seat 223. Under the action of the friction force, when the rotating inner ring seat 223 can move relative to the rotating round seat 211, the driving motor 225 will only drive the rotating inner ring seat 223 to rotate, and the rotating round seat 211 remains Differently, after the arc-shaped support plate 214 rotates outward to position the cutting tool 6, the arc-shaped support plate 214 can no longer rotate outward, which means that the rotating inner ring seat 223 and the rotating round seat 211 can no longer move relative to each other. Therefore, at this time, the driving action of the driving motor can directly drive the rotating round seat 211 to rotate around the central axis through the rotating inner ring seat 223. This rotation action can drive the different upper surfaces of the cutting tool 6 to rotate in turn to the bottom of the polishing wheel 43, so as to achieve comprehensive polishing of the cutting tool 6 by the polishing wheel 43.

[0081] In order to achieve the position exchange of the cutting tool 6 , the present invention makes the following design: a plurality of lifting bolts 312 are provided; a hydraulic cylinder 311 is provided in the bottom groove 13 , and the lifting bolt 312 is connected to the output end of the hydraulic cylinder 311 .

[0082] During the process of changing the position of the cutting tool 6, the driving motor 225 must first be driven in reverse to drive the arc-shaped support plate 214 to reset to the initial position, thereby releasing the fixing effect on the cutting tool 6. Then, the lifting bolt 312 is driven to rise by the hydraulic cylinder 311, thereby driving the cutting tool 6 to move up into the top groove 14.

[0083] After moving into the top groove 14, the cutting tool 6 in the top groove 14 also needs to be fixed: the driving motor 225 drives the rotating inner ring seat 223 to rotate clockwise, and the rotating inner ring seat 223 drives one end of the rotating bolt 224 to rotate, and the other end of the rotating bolt 24 follows and is dragged out to the side of the rotating inner ring seat 223, thereby driving the gear translation bolt 222 to translate inward (slide along the translation groove 226), and under the translation action of the gear translation bolt 222, the shaft tooth 221 rotates and drives the rotating shaft 213 to rotate, thereby driving the arc-shaped support plate 214 to rotate outward to the cutting tool The tool 6 is positioned. After the cutting tool 6 is positioned, due to the reverse limiting effect of the cutting tool 6, the driving motor 225 continues to rotate and cannot drive the arc-shaped support plate 214 to continue to rotate through the above-mentioned transmission structure. Therefore, under the drive of the transmission structure, the whole is directly driven to rotate around the central axis, which also drives the rotating round seat 211 to rotate. The rotation of the rotating round seat 211 can directly drive the arc-shaped support plate 214 to rotate around the central axis, thereby driving the cutting tool 6 to rotate, and cooperating with the work of the double-sided polishing mechanism 4 to complete the comprehensive polishing of the upper end surface of the cutting tool 6.

[0084] The present invention designs the installation structure of the polishing wheel 43, such as Figure 1 , Figure 2 and Figure 8 As shown, a mounting platform 41 is provided on the side of the chassis 11, a polishing shaft 42 is rotatably provided on the mounting platform 41, and polishing wheels 43 are rotatably provided on the upper and lower ends of the polishing shaft 42;

[0085] A third motor 44 is disposed inside the polishing shaft 42 , and an output end of the third motor 44 is connected to the shaft of the polishing wheel 43 via a transmission belt 45 .

[0086] An installation slot 46 is defined in the installation platform 41 . A driving shaft 47 is rotatably disposed in the installation slot 46 . The polishing shaft 42 is rotatably disposed on the installation slot 46 via the driving shaft 47 .

[0087] The third motor 44 drives the polishing wheel 43 to rotate through the transmission belt 45 , and the polishing wheel 43 rotates to polish the cutting tool 6 .

[0088] During the position conversion process of the cutting tool 6, if the polishing wheel 43 is directly above the bottom groove 13, the polishing wheel 43 will stop the cutting tool 6. In order to avoid the polishing wheel 43 stopping the conversion of the cutting tool 6, the present invention makes the following design, such as Figure 8 and Fig. 9As shown, a transmission gear 48 is connected to the lower end of the drive shaft 47, and a forward drive wheel 49 and a reverse drive wheel 410 are respectively provided on both sides of the transmission gear 48. The forward drive wheel 49 and the reverse drive wheel 410 are both provided with driving teeth 411. A first motor 412 is connected to the bottom of the forward drive wheel 49, and a second motor 413 is connected to the bottom of the reverse drive wheel 410. The first motor 412 drives the forward drive wheel 49 to rotate clockwise, and the second motor 413 drives the reverse drive wheel 410 to rotate counterclockwise.

[0089] In this embodiment, the driving teeth 411 on the forward driving wheel 49 or the reverse driving wheel 410 mesh with the transmission gear 48 to drive the polishing shaft 42 to rotate between the bottom plate 11 and the top plate 12 or to rotate the polishing wheel 43 to the side. That is to say, when the cutting tool 6 needs to be polished, the forward driving wheel 49 rotates clockwise under the drive of the first motor 412, and the driving teeth 411 thereon drive the transmission gear 48 to rotate counterclockwise, thereby driving the polishing shaft 42 to rotate through the driving shaft 47. The rotation of the polishing shaft 42 drives the polishing wheel 43 to rotate between the bottom plate 11 and the top plate 12.

[0090] When the cutting tool 6 needs to change position or continue to be transported, the reverse drive wheel 410 rotates counterclockwise under the drive of the second motor 413, and the driving tooth 411 thereon drives the transmission gear 48 to rotate clockwise, thereby driving the polishing shaft 42 to rotate through the driving shaft 47. The rotation of the polishing shaft 42 drives the polishing wheel 43 to rotate to the side of the top plate 12. At this time, the polishing wheel 43 is not between the top groove 14 and the bottom groove 13, and will not affect the position change of the cutting tool 6.

[0091] In order to unload the polished cutting tool 6, a unloading mechanism 5 is arranged between the bottom plate 11 and the top plate 12; the unloading mechanism 5 includes an unloading conveyor belt 51 arranged between the top plate 12 and the bottom plate 11, a conveying roller 52 arranged in the unloading conveyor belt 51, and a mounting frame 53 arranged on the conveying roller 52.

[0092] When unloading, the second drive motor 335 rotates in the opposite direction to drive the second arc-shaped support plate 324 to rotate to the initial position, releasing the positioning effect on the cutting tool 6, and the cutting tool 6 falls from the top groove 14 to the unloading conveyor belt 51 under the action of gravity.

[0093] In summary, the implementation process of the present invention is:

[0094] The cutting tool 6 is placed in the bottom groove 13, and the driving motor 225 drives the arc-shaped support plate 214 to rotate outward to position the cutting tool 6. Then, the cutting tool 6 is driven to rotate by rotating the round seat 211 and the arc-shaped support plate 214. The bottom plate 11 and the top plate 12 rotate to drive the cutting tool 6 to move to the polishing station. The first motor 412 drives the polishing wheel 43 to rotate to the top of the cutting tool 6 through the polishing shaft 42. The third motor 44 drives the polishing wheel 43 to rotate through the transmission belt 45. The polishing wheel 43 rotates to polish the upper end surface of the cutting tool 6.

[0095] After polishing is completed, the second motor 413 drives the polishing wheel 43 to rotate to the side of the top plate 12 through the driving shaft 47. At this time, the reverse driving driving motor 225 drives the arc-shaped support plate 214 to reset to the initial position, releasing the positioning effect on the cutting tool 6. Then, the cutting tool 6 is lifted into the top groove 14 through the lifting bolt 312. The driving motor 225 drives the arc-shaped support plate 214 to rotate outward to position the cutting tool 6. Then, the cutting tool 6 is driven to rotate by rotating the round seat 211 and the arc-shaped support plate 214. The first motor 412 runs through the polishing shaft 42 to drive the polishing wheel 43 to rotate to the bottom of the cutting tool 6. The third motor 44 drives the polishing wheel 43 to rotate through the transmission belt 45. The polishing wheel 43 rotates to achieve comprehensive polishing of the lower end surface of the cutting tool 6.

[0096] After polishing is completed, the second motor 413 drives the polishing wheel 43 to rotate to the side of the top plate 12 through the driving shaft 47, and the bottom plate 11 and the top plate 12 rotate to drive the cutting tool 6 to the top of the unloading mechanism 5. The second driving motor 335 rotates in the opposite direction to drive the second arc-shaped support plate 324 to rotate to the initial position, releasing the positioning effect on the cutting tool 6. The cutting tool 6 falls from the top groove 14 to the unloading conveyor belt 51 under the action of gravity.
