Description

Technical Field

[0001] The invention belongs to the technical field of grinding processing equipment, and in particular relates to a grinding processing device for a tread groove of a tire mold. Background Art

[0002] The inner wall of the tire mold needs to be pre-processed with a concave and convex pattern that matches the tire product. Since the tire mold needs to be composed of several arc-shaped partial molds, it also needs to be processed one by one during processing. This process inevitably requires frequent disassembly. For scenes that require frequent loading and unloading, it is preferred to use a technical solution that automatically clamps and fixes the workpiece by lowering the tool, which can greatly reduce the number of manual operation steps.

[0003] However, in this technical solution, due to reasons such as different workpiece thicknesses, different tool lengths, and spring force attenuation, it is often unknown whether the clamping force on the workpiece is sufficient when the tool contacts the workpiece. If the workpiece has not yet obtained sufficient clamping force when the tool is pressed down, then whether it is pushing and adjusting the workpiece or contacting the workpiece with the high-speed rotating tool, the workpiece will produce random abnormal deviations. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention proposes a mold groove grinding processing device that can automatically clamp and fix the workpiece before the tool contacts the workpiece; in order to solve the problem that in the traditional automatic clamping mechanism, the workpiece that has not been stably clamped is pushed or contacts the high-speed rotating tool and is easily offset; this scheme creatively proposes a downward pressure type power clutch mechanism and a multi-axis motion mechanism, which is linked by the downward pressure type power clutch mechanism, and the power transmission between the workpiece adjustment motor and the clamping roller can be carried out only after the pressure between the clamping roller and the workpiece reaches a certain level, thereby avoiding the problem that the workpiece that has not been stably clamped is easily offset when being adjusted.

[0005] In addition, through the linkage of the multi-axis motion mechanism, power transmission between the drill drive motor and the grinding tool will not be carried out until the pressure between the clamping roller and the workpiece reaches a certain level, thereby avoiding the problem of the workpiece that has not been stably clamped being easily offset when being adjusted.

[0007] Through the downward pressure action when the drill bit descends, the extrusion pressure between the clamping roller and the mold parts can be automatically increased, thereby achieving stable clamping of the mold parts, thereby avoiding the problem of workpiece loosening caused by active adjustment of the workpiece adjustment motor due to unstable clamping of traditional grinding processing devices.

[0008] Furthermore, the downward pressure sensing component includes a lifting bracket, a piston return spring, a downward pressure applying spring and a downward pressure plate, the lifting bracket is arranged on the workpiece clamping adjustment mechanism, the lifting bracket is provided with a downward pressure sensing chamber, a downward pressure sensing piston is slidably provided in the downward pressure sensing chamber, the piston return spring is arranged between the downward pressure sensing chamber and the downward pressure sensing piston, and the downward pressure applying spring is arranged between the downward pressure sensing piston and the downward pressure plate.

Only when the extrusion pressure between the clamping roller and the mold part reaches a certain level, can the position adjustment of the mold part by the workpiece adjustment motor be realized; thereby ensuring that the adjustment of the mold part by the workpiece adjustment motor is accurate and stable, avoiding the problem of abnormal displacement of the mold parts.

[0046] Through the downward pressing action when the drill bit descends, the extrusion pressure between the clamping roller 13 and the mold part 46 can be automatically increased, thereby achieving stable clamping of the mold part 46, thereby avoiding the problem of workpiece loosening caused by active adjustment of the workpiece adjustment motor 14 due to unstable clamping of traditional grinding processing devices.

[0047] The workpiece clamping and adjusting mechanism 3 comprises a supporting assembly 41 and a pressing and lifting assembly 42 . The pressing and lifting assembly 42 is symmetrically arranged on the supporting assembly 41 .

[0048] The support assembly 41 includes a bottom plate 43 and a roller bracket 44 . The roller bracket 44 is symmetrically arranged on the bottom plate 43 . A support roller 45 is rotatably arranged on the roller bracket 44 . A mold part 46 is placed between the support roller 45 and the pressing roller 13 .

[0049] The clamping lifting assembly 42 includes a clamping bracket 47, a vertical sleeve 49 and a rising reset spring 50. The clamping bracket 47 is symmetrically arranged on the base plate 43. The clamping bracket 47 is symmetrically provided with a vertical guide rod 48. The vertical sleeve 49 is arranged on the lifting bracket 7. The vertical sleeve 49 is snap-fitted and slidably arranged in the vertical guide rod 48. The rising reset spring 50 is arranged between the vertical guide rod 48 and the vertical sleeve 49. The lower pressure plate 51 is snap-fitted and slidably arranged on the vertical sleeve 49.

[0050] The movement of the downward pressure sensing component 4 can be guided by the clamping lifting component 42. On the one hand, it can be suitable for mold parts 46 of different thickness specifications. On the other hand, it can automatically control the clamping roller 13 to rise when rising, resetting and retracting, thereby realizing automatic unlocking of the mold part 46.

[0051] The downward pressure sensing component 4 includes a lifting bracket 7, a piston return spring 10, a downward pressure applying spring 11 and a downward pressure plate 51. The lifting bracket 7 is arranged on the workpiece clamping adjustment mechanism 3. The lifting bracket 7 is provided with a downward pressure sensing chamber 8. A downward pressure sensing piston 9 is slidably provided in the downward pressure sensing chamber 8. The piston return spring 10 is arranged between the downward pressure sensing chamber 8 and the downward pressure sensing piston 9. The downward pressure applying spring 11 is arranged between the downward pressure sensing piston 9 and the downward pressure plate 51.

[0052] The workpiece adjustment assembly 5 includes a bearing 12, a clamping roller 13 and a workpiece adjustment motor 14. The bearing 12 is arranged in the lifting bracket 7. The clamping roller 13 is provided with a roller long axis 19. The roller long axis 19 is arranged in the bearing 12. A polygonal sliding part 20 is also provided on the roller long axis 19. The workpiece adjustment motor 14 is arranged on the roller clutch assembly 6.

[0053] The roller clutch assembly 6 includes a first hydraulic transmission box 15, a first hydraulic pipeline 16, a first clutch plate 17 and a second clutch plate 18. The first hydraulic transmission box 15 is arranged on the lifting bracket 7, and the workpiece adjustment motor 14 is arranged on the first hydraulic transmission box 15. The output shaft of the workpiece adjustment motor 14 is rotatably connected to the end of the roller long axis 19. The first hydraulic pipeline 16 is arranged between the first hydraulic transmission box 15 and the downward pressure sensing chamber 8. The first clutch plate 17 is engaged and slidably arranged on the polygonal sliding part 20, and the second clutch plate 18 is fixedly connected to the output shaft of the workpiece adjustment motor 14.

[0054] Through the penetration of the first hydraulic pipeline 16, when the downward pressure sensing piston 9 is pressed down, the liquid in the downward pressure sensing chamber 8 can be automatically supplied to the first hydraulic transmission box 15. Only when the extrusion pressure between the clamping roller 13 and the mold part 46 reaches a certain level, can the position adjustment of the mold part 46 by the workpiece adjustment motor 14 be realized; thereby ensuring that the adjustment of the mold part 46 by the workpiece adjustment motor 14 is accurate and stable, avoiding the problem of abnormal displacement of the mold part 46.

[0055] The multi-axis motion mechanism 2 includes a beam assembly 21, a transverse sliding assembly 22, a dust collecting assembly 23 and a drill assembly 24. The beam assembly 21 includes a portal beam 25. A hydraulic cylinder 26 is provided on the portal beam 25. A lifting beam 27 is provided on the telescopic part of the hydraulic cylinder 26. Both ends of the lifting beam 27 are provided with lower pressure blocks 28 corresponding to the lower pressure plate 51. The transverse sliding assembly 22 is slidably arranged on the lifting beam 27, and the dust collecting assembly 23 is arranged on the transverse sliding assembly 22.

[0056] Through the downward pressure action when the drill bit descends, the engagement of the third clutch plate 36 and the fourth clutch plate 37 can be automatically controlled, thereby realizing power transmission to the grinding tool 38, thereby avoiding the problem of the traditional grinding processing device causing the workpiece to loosen after the rotating tool contacts the workpiece due to unstable clamping.

[0057] The lateral sliding assembly 22 includes a slide plate 29 and a drill drive motor 30. The slide plate 29 is slidably arranged on the lifting beam 27. The drill drive motor 30 is arranged on the slide plate 29. The dust collecting assembly 23 includes a dust collecting box 31. The dust collecting box 31 is arranged at the bottom of the slide plate 29. The dust collecting box 31 is provided with an upper dust collecting pipe 32 and a lower dust collecting pipe 33. The drill drive motor 30 is provided with a central spindle 39. The central spindle 39 is rotatably arranged in the dust collecting box 31 and the second hydraulic transmission box 34 and is provided with a polygonal sliding part 2 40 at the end. The third clutch plate 36 is engaged and slidably arranged in the polygonal sliding part 2 40.

[0058] The height and lateral coordinates of the grinding tool 38 can be adjusted by the hydraulic cylinder 26 and the slide plate 29. After the mold part 46 is clamped, the grinding tool 38 can be driven to rotate by the drill drive motor 30. Moreover, by driving the dust collecting assembly 23 through the central spindle 39, regardless of whether the third clutch plate 36 and the fourth clutch plate 37 are engaged, the central spindle 39 will collect small particles and dust at the working position through the negative pressure generated by itself.

[0059] The drill bit assembly 24 includes a second hydraulic transmission box 34, a second hydraulic pipeline 35, a third clutch plate 36, a fourth clutch plate 37 and a grinding tool 38. The second hydraulic pipeline 35 is arranged between the second hydraulic transmission box 34 and the downward pressure sensing chamber 8. The third clutch plate 36 and the fourth clutch plate 37 are rotatably arranged in the second hydraulic transmission box 34, and the grinding tool 38 is detachably arranged on the fourth clutch plate 37.

[0060] Through the penetration of the second hydraulic pipeline 35, when the downward pressure sensing piston 9 is pressed down, the liquid in the downward pressure sensing chamber 8 can be automatically supplied to the second hydraulic transmission box 34, thereby realizing the engagement of the third clutch plate 36 and the fourth clutch plate 37; thereby avoiding the problem of abnormal displacement of the mold part 46 when the high-speed rotating vertical guide rod 48 contacts the incompletely clamped mold part 46.

[0061] When in use, in the initial state, the vertical sleeve 49 is located away from the support assembly 41 together with the lifting bracket 7 under the elastic force of the rising return spring 50. At this time, the gap between the pressing roller 13 and the support roller 45 is large, and the mold part 46 to be ground is placed on the support roller 45.

[0062] Then, the lifting beam 27 is lowered as a whole by the extension of the hydraulic cylinder 26. When the lower pressing block 28 contacts and squeezes the lower pressing plate 51, the lifting bracket 7 is lowered together with the vertical sleeve 49 until the pressing roller 13 abuts against the mold part 46.

[0063] Then, the lifting bracket 7 stops descending, and when the pressing top block 28 continues to press the pressing plate 51 downward, the pressing plate 51 will slide downward along the vertical sleeve 49, and at the same time, the pressing sensing piston 9 will retract toward the pressing sensing chamber 8 by compressing the pressing spring 11.

[0064] When the downward pressure sensing piston 9 retracts toward the downward pressure sensing chamber 8, the liquid in the downward pressure sensing chamber 8 will enter the first hydraulic transmission box 15 and the second hydraulic transmission box 34 at the same time. Since the pressures in the first hydraulic transmission box 15 and the second hydraulic transmission box 34 which are interconnected are equal, the engagement timing of the first clutch plate 17 and the second clutch plate 18 should be roughly similar to the engagement timing of the third clutch plate 36 and the fourth clutch plate 37. Example

[0065] When the downward pressure sensing piston 9 retracts toward the downward pressure sensing chamber 8, a portion of the liquid inside the downward pressure sensing chamber 8 will enter the first hydraulic transmission box 15 through the first hydraulic pipe 16, thereby pushing the first clutch plate 17 to slide along the polygonal sliding portion 20 toward the second clutch plate 18. When the first clutch plate 17 and the second clutch plate 18 are squeezed and combined, the workpiece adjustment motor 14 can drive the clamping roller 13 to rotate and control the movement of the mold part 46 during the processing. Since the mold part 46 is an arc-shaped as a whole and the tool processing position is its lowest point, for the annular uniform distribution feature of the tire pattern, the tool only needs to perform a simple repetitive procedure, and the processing can be continued by adjusting the mold part 46.

[0066] Since the combination of the first clutch plate 17 and the second clutch plate 18 requires a certain pressure between the clamping roller 13 and the mold part 46, when the mold part 46 has not been clamped, even if the workpiece adjustment motor 14 is started, the clamping roller 13 cannot be driven, thereby avoiding the problem of abnormal deviation caused by the clamping roller 13 pushing the mold part 46 that has not been clamped. Example

[0067] When the pressure sensing piston 9 retracts toward the pressure sensing chamber 8, a portion of the liquid inside the pressure sensing chamber 8 enters the second hydraulic transmission box 34 through the second hydraulic pipe 35, thereby pushing the third clutch plate 36 to slide along the second polygonal sliding portion 40 toward the fourth clutch plate 37. When the third clutch plate 36 and the fourth clutch plate 37 are squeezed and combined, the drill drive motor 30 can drive the grinding tool 38 to rotate;

[0068] Since the combination of the third clutch plate 36 and the fourth clutch plate 37 requires a certain pressure between the clamping roller 13 and the mold part 46, when the mold part 46 has not been clamped, even if the drill drive motor 30 is started, the grinding tool 38 cannot be driven, thereby avoiding the problem of abnormal deviation caused by the high-speed rotating grinding tool 38 contacting the mold part 46 that has not been clamped.

[0069] When the central spindle 39 rotates, regardless of whether the third clutch plate 36 and the fourth clutch plate 37 are engaged, the central spindle 39 can drive the impeller inside the dust box 31 to rotate and generate negative pressure, thereby collecting the debris at the end of the lower dust collecting pipe 33. The debris accumulates inside the dust box 31 and only needs to be cleaned regularly.

[0070] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0071] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
