Description

Technical Field

[0001] This invention relates to the field of machining technology, and more specifically to a grinding device for parts processing based on Internet of Things (IoT) technology. Background Technology

[0002] Grinding is a mechanical processing method for removing material, referring to the process of removing excess material from a workpiece using abrasive tools. It is one of the most widely used material removal methods. Many shaft parts are available on the market, along with various grinding devices for grinding the outer surfaces of these parts. For example, Chinese Patent No. CN 220971885 U discloses a grinding device for mechanical parts. This patent can improve the uniform force distribution on both sides of the part, effectively reducing bending deformation. However, this patent uses two sets of grinding wheels to grind the surface of the part. While this grinding method reduces bending deformation, because both sets of grinding wheels are in line contact with the surface of the part, i.e., linear grinding, the grinding efficiency is low and the grinding quality cannot be guaranteed.

Detailed Implementation

[0034] The above-mentioned and other technical features and advantages of the present invention will be described in more detail below with reference to the accompanying drawings. Example

[0035] This embodiment provides a technical solution: a grinding device for parts processing based on Internet of Things (IoT) technology, such as... Figure 1 As shown, it includes a machine tool base 1, a two-axis gantry 2, two sets of drive clamping mechanisms, a grinding mechanism 4, and a control system. The control system is used to control the operation of the drive clamping mechanism, the two-axis gantry 2, and the grinding mechanism 4. The control system can be a PLC control system, which controls the operation of the entire device through the corresponding PLC program to realize the Internet of Things control of the entire device operation.

[0036] like Figure 1 As shown, the machine tool base 1 has a horizontal part and a vertical part fixed on both sides of the horizontal part. Both the horizontal part and the vertical part can be made of steel material by casting and welding to increase the stability of the center of gravity of the whole device, thereby ensuring the stability of the device during operation.

[0037] like Figure 1 As shown, the two ends of the two-axis truss 2 are respectively installed on the two vertical parts of the machine tool base 1, that is, directly above the shaft-type parts to be processed. The two-axis truss 2 includes two vertical axes and a horizontal axis. Since the two-axis truss 2 is an existing and conventional technology, its specific detailed structure will not be described in detail here.

[0038] like Figure 1 As shown, two sets of drive clamping mechanisms are respectively installed on two vertical parts of the machine tool base 1. The cooperation of the two drive clamping mechanisms can realize the clamping and fixing of the shaft parts to be processed and their axial rotation. The drive clamping mechanism includes a telescopic device 51 installed on the vertical part of the machine tool base 1. The telescopic device 51 can be a hydraulic cylinder, a push electric cylinder or a pneumatic cylinder. The telescopic end of the telescopic device 51 is equipped with a third motor 52. The output end of the third motor 52 is fixed with a stop block 53. That is, by extending the telescopic device 51 of the two drive clamping mechanisms, the two ends of the shaft parts to be processed are pressed and fixed. Then, by running the two third motors 52 synchronously, in the same direction and at the same speed, the shaft parts to be processed can be driven to rotate along their axial direction.

[0039] like Figures 1-5As shown, the grinding mechanism 4 is mounted on the moving end 21 of the two-axis truss 2, allowing it to move laterally and vertically via the two-axis truss 2. The grinding mechanism 4 includes two upper rotating rollers 41 mounted on the upper side of the moving end 21 of the two-axis truss 2 and two lower rotating rollers 42 mounted on the lower side of the moving end 21 of the two-axis truss 2. Both the upper and lower rotating rollers 41 are parallel to the axial direction of the shaft-like part to be processed. The two upper rotating rollers 41 and the two lower rotating rollers 42 are connected by a grinding belt 46. The grinding mechanism 4 is moved laterally and vertically via the two-axis truss 2. When in motion, the grinding belt 46 between the two lower rotating rollers 42 contacts the outer circumferential surface of the rotating shaft-like part to be processed. The grinding belt 46 itself has a certain elasticity, and the grinding belt 46 will be squeezed and deformed by the shaft-like part to be processed, fitting against the upper half of the outer contour of the shaft-like part to be processed, so that the grinding belt 46 and the shaft-like part to be processed can achieve surface contact, increasing the grinding effect. In addition, the height of the grinding mechanism 4 can be controlled by the two-axis gantry 2, and the pressure between the grinding belt 46 and the outer circumferential surface of the shaft-like part to be processed can be adjusted to control the grinding pressure.

[0040] like Figures 6-7 As shown, the outer surface of the grinding belt 46 is provided with a plurality of evenly distributed grinding ribs 461, and the plurality of grinding ribs 461 are all arranged along the length direction of the grinding belt 46. The arrangement of grinding ribs 461 can increase the grinding effect and increase the grinding consumption of the grinding belt 46, and reduce the number of times the grinding belt 46 is replaced. The grinding ribs 461 on the grinding belt 46 are divided into rough grinding section and fine grinding section, which can adapt to different grinding needs, and can also perform rough grinding first and then fine grinding.

[0041] like Figures 3-5 As shown, both ends of the two lower rollers 42 are provided with a locking component and a driving component 48. The locking component is used to prevent the lower rollers 42 from rotating on their own, and the driving component 48 is used to unlock the locking component and drive the lower rollers 42 to rotate, so as to drive the grinding belt 46 to rotate circumferentially, and to move different sections of the grinding belt 46 between the two lower rollers 42, thereby realizing the exchange of the rough grinding section and the fine grinding section. At the same time, the grinding position of the grinding belt 46 can be changed, consuming the grinding ridges 461 at different positions.

[0042] like Figure 4 and Figure 8 As shown, two symmetrically arranged connecting rods 435 are provided on both sides of the lower end of the moving end 21 of the two-axis truss 2. The rotating shaft of the lower rotating roller 42 is rotatably connected to the connecting rods 435. The drive assembly 48 includes an airtight cavity ring 483 fixed to the connecting rods 435. The airtight cavity ring 483 is airtightly rotatably connected to the rotating shaft of the lower rotating roller 42. An air connector 484 is fixed on the outer circumference of the airtight cavity ring 483. The air connector 484 is connected to an external air pump through an air pipe. High-pressure air can be injected into the airtight cavity ring 483 or extracted from the airtight cavity ring 483 by the air pump.

[0043] A rotating wheel 481 is fixed to the end of the shaft of the lower rotating roller 42. An annular airbag 482 is installed on the outer circumference of the rotating wheel 481. The shaft of the lower rotating roller 42 and the rotating wheel 481 share an inner channel. The annular airbag 482 is connected to the inner channel. When the annular airbag 482 is in a contracted state, it cannot contact the outer circumference of the shaft part to be processed. When the annular airbag 482 is inflated, its lower end is lower than the lowest end of the grinding rib 461, and the annular airbag 482 can contact the outer circumference of the shaft part to be processed, driving the lower rotating roller 42 to rotate, which in turn drives the grinding belt 46 to rotate, adjusting the position of the grinding belt 46 corresponding to the shaft part to be processed. Specifically, the rotation size of the grinding belt 46 is precisely controlled by the rotation speed of the third motor 52 and the contact time between the annular airbag 482 and the outer circumference of the shaft part to be processed.

[0044] like Figure 8 As shown, the locking assembly includes an airtight hole 493 communicating with the inner channel and a through groove 491 communicating with the airtight hole 493. The airtight hole 493 is arranged along the axial direction of the lower roller 42. The two ends of the through groove 491 pass through the rotating shaft of the lower roller 42. A piston 494 is arranged inside the airtight hole 493. A pusher is fixed to the piston 494 by a connecting rod. The pusher includes a connecting block 4921 arranged in the through groove 491. Ring blocks 4922 are fixed at both ends of the connecting block 4921. The ring blocks 4922 are sleeved on the outside of the rotating shaft of the lower roller 42. A plurality of pins 4923 are fixed on one side of the ring blocks 4922. A plurality of slots 4924 are opened on the connecting rod 435, and the slots 4924 are adapted to correspond with the pins 4923.

[0045] In use, high-pressure air is injected into the airtight cavity ring 483 by an air pump. The high-pressure air enters the annular airbag 482 through the inner channel, causing the annular airbag 482 to expand. At the same time, the high-pressure air pushes the piston 494 away from the rotary wheel 481, and the pin 4923 disengages from the slot 4924. Then, the two-axis truss 2 moves downward, so that the annular airbag 482 contacts the outer circumferential surface of the rotating shaft part to be processed, which drives the rotary wheel 481 and the lower rotary roller 42 to rotate, and further causes the grinding belt 46 to rotate. After the grinding belt 46 is rotated to the corresponding position, the high-pressure air is extracted by the air pump, the annular airbag 482 contracts, and the piston 494 will also move to its original position due to the air pressure. The pin 4923 is inserted into the slot 4924. That is, the lower rotary roller 42 and the connecting rod 435 are fixed by the locking assembly to prevent the grinding belt 46 from rotating with the shaft part to be processed when grinding the outer circumferential surface of the shaft part.

[0046] like Figure 8As shown, the outer circumferential surfaces of the two upper rotating rollers 41 and the two lower rotating rollers 42 are all provided with annular grooves, and embedded gears 471 are provided in the annular grooves. The embedded gears 471 on the two upper rotating rollers 41 and the two lower rotating rollers 42 are connected by a toothed belt 472, and the toothed belt 472 is circumferentially fixed to the inner surface of the grinding belt 46. The setting of the embedded gears 471 and the toothed belt 472 can increase the stability of the transmission between the grinding belt 46 and the upper rotating rollers 41 and the lower rotating rollers 42, so as to prevent slippage.

[0047] In use, after the shaft-like parts to be processed are clamped and fixed by two sets of drive clamping mechanisms, the shaft-like parts to be processed are driven to rotate by the two sets of drive clamping mechanisms. Then, the grinding mechanism 4 is moved by the two-axis truss 2 so that the grinding belt 46 between the two lower rotating rollers 42 contacts the outer circumferential surface of the shaft-like parts to be processed, thereby realizing the grinding of the outer circumferential surface of the shaft-like parts to be processed. By driving the grinding mechanism 4 to move along the axial direction of the shaft-like parts to be processed by the two-axis truss 2, the entire outer surface of the shaft-like parts to be processed can be ground. When working on stepped shaft-like parts, the entire outer circumferential surface can also be ground by the grinding belt 46. Example

[0048] This embodiment is a further optimization based on Embodiment 1. The parts that are the same as those described above will not be repeated here. Figures 2-5 As shown, to further better realize the present invention, the following configuration is specifically adopted: In this embodiment, the grinding mechanism 4 is equipped with an extension component 43 and a height adjustment component 44. The extension component 43 is located on the lower side of the moving end 21 of the two-axis truss 2 and is used to adjust the distance between the two lower rollers 42. The height adjustment component 44 is located on the upper side of the moving end 21 of the two-axis truss 2 and is used to adjust the height of the two upper rollers 41. By cooperating with the extension component 43 and the height adjustment component 44, the distance between the two lower rollers 42 can be adjusted, thereby adjusting the size of the grinding belt 46 between the two lower rollers 42 to adapt to grinding operations of shaft parts of different diameters.

[0049] like Figure 4 As shown, the extension component 43 includes two rotating shafts 434 rotatably mounted on the lower side of the moving end 21. Two connecting rods 435 on the corresponding sides are respectively fixed to the two ends of one rotating shaft 434, that is, a connecting rod 435 is fixed to both ends of the two rotating shafts 434. Both rotating shafts 434 are fixed with driven gears 433, and the two driven gears 433 are meshed and connected. The moving end 21 of the two-axis truss 2 is fixed with a first motor 431. The output end of the first motor 431 is fixed with a driving gear 432. The driving gear 432 meshes and drives one of the driven gears 433.

[0050] During operation, the first motor 431 is controlled by the control system, which in turn drives the two rotating shafts 434 to rotate in opposite directions through the two driven gears 433. The connecting rods 435 on both sides will also flip in opposite directions, thereby causing the two lower rotating rollers 42 to move closer or further away from each other, adjusting the distance between the two lower rotating rollers 42. During this process, the locking component must be released first so that the two connecting rods 435 can rotate.

[0051] like Figure 5 As shown, the height adjustment assembly 44 includes a bidirectional lead screw 442 rotatably mounted on the upper side of the moving end 21 of the two-axis truss 2. Two symmetrically arranged moving seats 443 are threaded onto the bidirectional lead screw 442. A second motor 441 that drives the bidirectional lead screw 442 to rotate is mounted on the moving end 21 of the two-axis truss 2. Support blocks 444 are hinged to both moving seats 443. U-shaped frames 445 are hinged to one side of the inner end of the two support blocks 444 and the other side of the inner end of the two support blocks 444. Two upper rotating rollers 41 are rotatably mounted on the two U-shaped frames 445 respectively.

[0052] During operation, the control system controls the second motor 441 to run, the bidirectional lead screw 442 to rotate, which in turn drives the two moving seats 443 to move closer or further apart, thereby causing the two U-shaped frames 445 to rise or fall, and adjusting the height of the two upper rotating rollers 41.

[0053] The height adjustment component 44 works in conjunction with the extension component 43. When the distance between the two lower rollers 42 is adjusted by the extension component 43, the size of the grinding belt 46 between the two lower rollers 42 will also be adjusted adaptively. At this time, the height of the two upper rollers 41 needs to be adjusted by the height adjustment component 44 to prevent the grinding belt 46 from being taut or loose.

[0054] When dealing with stepped shaft-like parts, the distance between the two lower rollers 42 needs to be adjusted to a larger size to avoid interference between the drive assembly 48 and the stepped shaft-like parts. Example

[0055] This embodiment is a further optimization based on Embodiment 1. The parts that are the same as those described above will not be repeated here. Figures 2-5 As shown, to further better realize the present invention, the following arrangement is adopted: In this embodiment, two adsorption rollers 45 are added. The adsorption rollers 45 are made of sponge material. The two adsorption rollers 45 are installed as follows: connecting plates are fixed at both ends of the U-shaped frame 445. The adsorption rollers 45 are rotatably installed between the two connecting plates. The adsorption rollers 45 are pressed and adhered to the outer surface of the grinding belt 46, which can increase the cleaning of dust on the outer surface of the grinding belt 46.

[0056] When in use, some water can be absorbed inside the adsorption roller 45. When the grinding belt 46 rotates, the wet adsorption roller 45 can adsorb the dust on the outer surface of the grinding belt 46 onto the adsorption roller 45. Example

[0057] This embodiment is a further optimization based on Embodiment 1. The parts that are the same as those described above will not be repeated here. Figure 1 As shown, to further better realize the present invention, the following arrangement is specifically adopted: In this embodiment, a support mechanism 3 is added for positioning the height of the shaft-like parts to be machined and for lifting the shaft-like parts to be machined. The support mechanism 3 is installed on the transverse part of the machine tool base 1, and there are 1-2 sets of support mechanisms 3, and the operation of the support mechanism 3 is controlled by the control system.

[0058] like Figure 2 and Figure 9 As shown, the support mechanism 3 includes an electric push rod 31 fixed to the transverse part of the machine tool base 1. The telescopic end of the electric push rod 31 is fixed with two hollow sleeves 34 through the transverse rod. Both ends of the two hollow sleeves 34 are slidably provided with bending frames 35. The outer side of the bending frames 35 has an inclined part. The inclination angle of the inclined part is calculated. Support rollers 37 are rotatably installed between the inclined parts of the two bending frames 35 on the same side of the two hollow sleeves 34 (the same side here is based on the axis of the shaft part to be processed). That is, the two support rollers 37 are located on both sides of the axis of the shaft part to be processed. A bracket 32 ​​is fixed to the outer side of the electric push rod 31. Both sides of the bracket 32 ​​have inclined guide parts 33. The inclined parts are provided with grooves 36. The corresponding guide parts 33 are slidably disposed in the corresponding grooves 36.

[0059] In use, the height of the hollow sleeve 34 can be controlled by operating the telescopic end of the electric push rod 31, which further adjusts the height of the two bending frames 35 and the support rollers 37. At the same time, the bending frame 35, under the action of the guide part 33 and the slide groove 36, extends and retracts relative to the hollow sleeve 34, thereby adjusting the distance between the two support rollers 37. This allows the two support rollers 37 to accommodate shaft parts of different outer diameters. The center of the shaft parts placed on the two support rollers 37 will always be concentric with the output end of the third motor 52, eliminating the need for operators to spend time adjusting, thus saving time. Furthermore, during operation, the two support rollers 37 also lift the shaft parts to be processed, reducing the burden on the two drive clamping mechanisms and increasing safety performance.

[0060] The above are merely preferred embodiments of the present invention and are illustrative in nature, not restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, all of which will fall within the protection scope of the present invention.
