Technical Field
[0001] This invention relates to a grinding wheel dressing device and a grinding machine, and more particularly to a grinding wheel dressing device and a grinding machine capable of reducing vibration. Background Technology
[0002] Chinese Patent No. 212665812U discloses a dressing device that can directly dress grinding wheels on a workpiece machining grinding machine. It is equipped with a spring to ensure that the grinding head is always in close contact with the surface of the grinding wheel body during the grinding process. During the dressing process, the grinding head may vibrate violently up and down due to the surface of the grinding wheel body being too rough or vibrations transmitted from other parts of the grinding machine, which in turn causes additional impact on the surface of the grinding wheel body, resulting in the dressed grinding wheel body surface not being round enough.
[0003] Therefore, it is necessary to design a grinding wheel dressing device and a grinding machine to overcome the above problems. Summary of the Invention
[0004] To address the problems encountered in the background technology, the present invention provides a grinding wheel dressing device and a grinding machine, which actively activates a clamping module to clamp and reinforce the dressing module, thereby reducing the vibration of the dressing module.
[0005] To achieve the above objectives, the present invention employs the following technical means:
[0006] A grinding wheel dressing device includes: a base having a through groove; a lifting module mounted on the base; a dressing module connected to the lifting module and extending vertically through the base along the through groove, the dressing module having a dressing body protruding from the lower surface of the base; the lifting module drives the dressing module to move vertically; the grinding wheel dressing device further includes a clamping module disposed on the base, the clamping module including a driving device, a moving member directly or indirectly connected to the driving device, and a clamping member located between the moving member and the dressing module, the moving member having a pressure-applying part on its side facing the clamping member, one side of the clamping member facing the moving member and having an abutment part, the opposite side of the clamping member having a clamping part, the clamping part facing the dressing module, when the driving device pushes the moving member, the pressure-applying part pushes against the abutment part, causing the clamping part to apply pressure to the dressing module, the dressing module being clamped by the clamping member and the side wall of the through groove.
[0007] Furthermore, the moving component includes a connecting block and a slider connected in sequence. The connecting block is connected to a connecting rod of the driving device. The slider includes a connecting portion connected to the connecting block and a sliding portion perpendicularly connected to the connecting portion. The sliding portion slides relative to the base. The pressure-applying portion protrudes laterally from the sliding portion, and the sliding portion is located below the driving device.
[0008] Furthermore, the base has a through-hole groove, the clamping member and the sliding part are housed in the groove, the groove is connected to the through groove from front to back, the front side of the trimming module is located in the groove, the rear side of the trimming module abuts against the side wall of the through groove, and the clamping member applies pressure to the trimming module from rearward within the groove.
[0009] Furthermore, the pressure-applying part is a rolling element, and the abutting part has an inclined abutting surface. The abutting surface protrudes relative to the side surface, and the included angle between the abutting surface and the side surface is greater than or equal to 150°. When the moving element moves, the pressure-applying part rolls from the side surface to the abutting surface, thereby applying pressure to the abutting part.
[0010] Furthermore, the knife-repairing module also includes a connecting seat installed on the lifting module, a knife-repairing seat located below the connecting seat, a knife-repairing body housed in the knife-repairing seat, a vertical rod installed on the knife-repairing seat and extending vertically through the connecting seat, and a buffer spring connecting the vertical rod and the connecting seat above the connecting seat.
[0011] Furthermore, it also includes a base plate and at least one elastic limiting member mounted on the base plate. The elastic limiting member has a base portion mounted on the base plate, at least one elastic portion connected to the base portion, and at least one limiting portion connected to the elastic portion. The limiting portion protrudes from the elastic portion toward the base and presses down on the base.
[0012] Furthermore, the elastic part is bow-shaped.
[0013] Furthermore, it also includes a drive cylinder connected to the base on the outside of the base, driving the base to slide between the limiting part and the bottom plate.
[0014] A grinding machine includes a worktable, a grinding wheel, a frame connecting the worktable and the grinding wheel, and a grinding wheel dressing device. The grinding wheel dressing device is mounted on the frame and located radially outward of the grinding wheel. When the grinding wheel is machining a workpiece, the grinding wheel dressing device moves along with the grinding wheel. A lifting module allows a tool dressing module to move towards and contact the grinding wheel, so that the grinding machine grinds the grinding wheel while machining the workpiece. When the grinding wheel dressing device is grinding the grinding wheel, the grinding wheel dressing device activates the clamping module.
[0015] Furthermore, it also includes a first vision measurement device mounted on the frame. The first vision measurement device includes a light source module, a camera module, and a first grating ruler. The light source module and the camera module are located on the left and right sides of the grinding wheel and can move up and down independently relative to the grinding wheel. The first grating ruler measures the vertical displacement of the camera module. The worktable has a second grating ruler that measures its horizontal displacement. The first vision measurement device is calibrated using the first grating ruler and the second grating ruler.
[0016] The grinding wheel dressing device and grinding machine of the present invention have the following technical effects:
[0017] The grinding wheel dressing device and grinding machine of the present invention can actively activate the clamping module to increase the stability of the dressing module when dressing the grinding wheel. Specifically, when the driving device pushes the moving part to move, and the pressure part reaches the preset maximum stroke, the pressure part applies pressure to the abutment surface of the clamping member, and the clamping part located on the opposite side of the clamping member applies pressure to the dressing module, so that the dressing module is jointly pressed by the clamping member and the side wall of the through groove, thereby increasing the stability of the entire dressing module and reducing its vibration amplitude. This can reduce the direct vibration caused by the dressing body directly contacting the overly rough grinding wheel surface, and also reduce the indirect vibration transmitted from other parts of the grinding machine, which is beneficial for the dressing module to dress a sufficiently round grinding wheel.

[0029] refer to Figure 1 and Figure 2 The grinding machine of the present invention has a worktable 1, a grinding wheel 2, and a frame 3 connecting the worktable 1 and the grinding wheel 2. The worktable 1 is used to place a workpiece, and the grinding wheel 2 is surrounded by a protective cover 20 for processing the workpiece. The grinding machine also has a grinding wheel dressing device 4, which is mounted on the frame 3 and located radially outside the grinding wheel 2. In this embodiment, the grinding wheel dressing device 4 is located on the upper side of the grinding wheel 2, so the top of the protective cover 20 is provided with an opening (not shown) to allow the grinding wheel 2 to contact the grinding wheel dressing device 4. In other embodiments, the grinding wheel dressing device 4 can be located on the left or right side of the grinding wheel 2. The grinding machine of the present invention can simultaneously start the grinding wheel 2 and the grinding wheel dressing device 4. When the grinding wheel 2 processes the workpiece, the grinding wheel dressing device 4 moves along with the grinding wheel 2, simultaneously processing the workpiece with the grinding wheel 2 and simultaneously grinding and dressing the grinding wheel 2 by starting the grinding wheel dressing device 4.
[0030] refer to Figures 1 to 3The grinding wheel dressing device 4 of the present invention mainly includes a base plate 41 for fixing the entire grinding wheel dressing device 4 to the frame 3, a base 42 mounted on the base plate 41, a lifting module 43 mounted on the base 42, a dressing module 44 connected to the lifting module 43, a clamping module 45 disposed on the base 42, an elastic limiting member 46 mounted on the base plate 41, and a housing 47 mounted on the base plate 41 and surrounding the other components, and a drive cylinder 48 fixed to the housing 47.
[0031] refer to Figure 2 , Figure 3 and Figure 5 The upper surface of the base plate 41 is provided with two sliding grooves 411 extending in the front-back direction, and the lower surface of the base 42 is provided with two slide rails 421 corresponding to and cooperating with the sliding grooves 411. The drive cylinder 48 is connected to the rear side of the base 42, driving the base 42 and other components installed on the base 42 to move in the front-back direction. In this embodiment, the thickness direction of the grinding wheel 2 is the front-back direction, so that the dressing module 44 can move along the thickness direction of the grinding wheel 2 to fully dress the grinding wheel 2. In short, the starting direction of the drive cylinder 48 is parallel to the thickness direction of the grinding wheel 2. If the thickness direction of the grinding wheel 2 is the left-right direction in other embodiments, then the drive cylinder 48 should be located on the left or right side of the base 42, and the sliding grooves 411 and the slide rails 421 are correspondingly arranged in the left-right direction.
[0032] refer to Figure 4 and Figure 5 In this embodiment, the base plate 41 has a through hole 412 extending vertically through itself, located between the two grooves 411. The base 42 has a through groove 422 extending vertically through itself, located above the through hole 412. The two are interconnected. The dressing module 44 protrudes from the lower surface of the base plate 41, passing through both the through groove 422 and the through hole 412, to contact the grinding wheel 2. In this embodiment, the through hole 412 and the through groove 422 are surrounded on four sides, forming four sidewalls 4221. In other embodiments, the dressing module 44 can be located on the outside of the base 42 and the base plate 41, with the through hole 412 and the through groove 422 connecting to the periphery of the base 42 and the base plate 41, so that the through groove 422 and the through hole 412 are surrounded on only three sides, or even formed by only two oblique sides.
[0033] refer to Figure 3 and Figure 5In this embodiment, the front half of the base 42 has a receiving groove 423, which is recessed downward from the upper surface of the base 42 and extends through the base 42 in a left-right direction to accommodate the clamping module 45. The receiving groove 423 is connected to the through groove 422 front and back, and a part of the trimming module 44 is located in the receiving groove 423. The left and right sides of the base 42 also each have a stepped portion 424 to cooperate with the elastic limiting portion 463. The base 42 further has a guide groove 425 recessed from the bottom surface of the receiving groove 423, and the guide groove 425 extends in a left-right direction.
[0034] refer to Figure 3 and Figure 5 The lifting module 43 mainly includes a vertical plate 431 fixed to the base 42, a linear motor 432 and a guide seat 433 mounted on the vertical plate 431, and a mounting plate 434 connected to the linear motor 432. In this embodiment, the linear motor 432 is located above the guide seat 433, while in other embodiments, the mounting positions of the linear motor 432 and the guide seat 433 can be reversed. The guide seat 433 has vertically extending guide rails 4331 on its surface facing the tool trimming module 44. The mounting plate 434 covers the guide rails 4331 and is connected to the guide rails 4331 through guide blocks 4341. The linear motor 432 drives the mounting plate 434 to move up and down along the guide rails 4331. The mounting plate 434 is used to mount the tool trimming module 44.
[0035] refer to Figures 3 to 5The trimming module 44 is mounted on the mounting plate 434. The trimming module 44 includes a connecting seat 441 mounted on the mounting plate 434, a trimming seat 442 located below the connecting seat 441, a trimming body 443 housed within the trimming seat 442, a vertical rod 444 protruding from the upper surface of the connecting seat 441, and a buffer spring 445 connecting the vertical rod 444 and the connecting seat 441 above the connecting seat 441. Although not shown in the accompanying drawings, the actual installation method of the vertical rod 444 is that the vertical rod 444 extends entirely through the connecting seat 441, and the lower end of the vertical rod 444 is mounted on the trimming seat 442. The trimming seat 442 passes through the through groove 422 and the through hole 412, and the front side of the trimming seat 442 is located within the receiving groove 423. The dressing body 443 is fixed to the dressing holder 442 by screws and protrudes from the lower surface of the dressing holder 442, appearing below the base plate 41. The dressing body 443 can be made of diamond or other materials with a hardness greater than that of the grinding wheel 2. When the grinding wheel 2 is processing a workpiece, the lifting module 43 can move the dressing module 44 toward the grinding wheel 2 and make it contact the grinding wheel 2, so that the grinding machine grinds the grinding wheel 2 while processing the workpiece.
[0036] refer to Figure 2 , Figure 5 and Figure 6 The clamping module 45 mainly includes a fixing plate 451 fixed to the upper surface of the base 42, a driving device 452 mounted on the fixing plate 451, a moving part 453 connected to the driving device 452, and a clamping part 454 received in the receiving groove 423. A portion of the fixing plate 451 is fixed to the upper surface of the base 42 by screws, and the remaining portion covers the upper part of the receiving groove 423. In this embodiment, the driving device 452 includes a micro-motion cylinder 4521 and a connecting rod 4522 connected to the moving part 453, driving the moving part 453 to move horizontally. In other embodiments, the micro-motion cylinder 4521 can be replaced by a linear motor.
[0037] refer to Figure 5 and Figure 6The movable component 453 includes a connecting block 4532 and a slider 4533 connected in sequence. The connecting block 4532 is I-shaped and is embedded in the top of the slider 4533, and the connecting block 4532 is connected to the connecting rod 4522. The slider 4533 includes a connecting portion A connecting the connecting block 4532 and a sliding portion B perpendicularly connected to the connecting portion A. In this embodiment, the connecting portion A extends downward relative to the connecting block 4532, and the sliding portion B extends to the left relative to the connecting portion A and is received in the receiving groove 423. At the same time, the sliding portion B is located below the fixing plate 451 and the driving device 452. When the driving device 452 causes the movable component 453 to move left and right, the sliding portion B slides left and right within the receiving groove 423.
[0038] refer to Figure 6 and Figure 7 The sliding part B has a pressure-applying part C on the side facing the pressing member 454. The pressure-applying part C protrudes horizontally from the sliding part B and contacts the pressing member 454. In this embodiment, the pressure-applying part C is a rolling element, such as a ball or roller. The sliding part B has a receiving groove (not labeled), in which most of the rolling element is received, and a small portion protrudes from the sliding part B. The rolling element moves left and right with the sliding part B and rolls along the surface of the pressing member 454 during the left and right movement. In other embodiments, the pressure-applying part C can be set as a stationary component, for example, the pressure-applying part C can be set as an arc-shaped protrusion integrally formed with the entire sliding part B.
[0039] refer to Figure 5 and Figure 6 The bottom surface of the sliding part B has a guide part D extending in the left-right direction, which is received in the guide groove 425 to limit the sliding part B to slide in the left-right direction.
[0040] refer to Figure 6 and Figure 8The middle portion of the clamping member 454 is housed within the receiving groove 423. One side S1 of the clamping member 454 faces the moving member 453 and has an abutment portion 4541. The clamping member 454 has a clamping portion 4542 on the opposite side S2. The clamping portion 4542 faces the trimming module 44 and is in the shape of a boss. The abutment portion 4541 protrudes relative to side S1, and the clamping portion 4542 protrudes relative to side S2. The abutment portion 4541 has an inclined abutment surface S3, which protrudes relative to side S1. The angle between the abutment surface S3 and side S1 is greater than or equal to 150°. When the driving device 452 drives the... Before the pressure part C reaches the preset maximum stroke, the pressure part C, as a rolling element, rolls along the side S1 where the abutment surface S3 is located to the abutment surface S3. When the driving device 452 drives the pressure part C to reach the preset maximum stroke, the pressure part C pushes against the abutment surface S3 of the abutment part 4541 of the clamping member 454. The clamping part 4542 of the clamping member 454 applies pressure to the tool repair seat 442 in the receiving groove 423. The rear side of the tool repair seat 442 abuts against the side wall 4221 of the through groove 422, so that the tool repair seat 442 is pressed together by the clamping member 454 and the side wall 4221 of the through groove 422, thereby increasing the stability of the entire tool repair module 44 and reducing its vibration amplitude.
[0041] In this embodiment, by tilting the contact surface S3, the pressure applied by the pressure-applying part C to the clamping member 454 can be controlled by controlling the travel distance of the pressure-applying part C on the contact surface S3. Setting the angle between the contact surface S3 and the side surface S1 to be greater than or equal to 150° ensures that more than 85% of the thrust generated by the driving device 452 can be converted into pressure from the clamping member 454 on the tool holder 442. In other embodiments, the contact surface S3 can be set as an arc surface, achieving a similar effect.
[0042] refer to Figure 6 Each of the left and right ends of the clamping member 454 is connected to a roughly L-shaped mounting part 4543. The top of the mounting part 4543 overlaps the upper surface of the base 42, and the left or right side of the mounting part 4543 is fixed to the base 42 by screws.
[0043] In the above embodiment, the clamping module starts moving in the left-right direction and finally clamps the tool trimming module 44 from front to back. In other embodiments, the positions of the relevant components can be appropriately changed, and the clamping module can be set to start moving in the front-back direction and clamp the tool trimming module 44 in the left-right direction; or, the starting direction and the final clamping direction of the clamping module can be set in the same direction.
[0044] refer to Figure 3 and Figure 5 This embodiment has two elastic limiting members 46, disposed on the left and right sides of the base 42. Each elastic limiting part 463 has a base 461 mounted on the base plate 41, at least one elastic part 462 connected to the base 461, and at least one limiting part 463 connected to the elastic part 462. The limiting part 463 protrudes from the elastic part 462 toward the base 42 and presses down on the stepped part 424. The base 42 slides between the limiting part 463 and the base plate 41. The elastic part 462 is arc-shaped. This arrangement utilizes the elastic limiting members 46 to absorb the vibration of the entire grinding wheel dressing device 4, increasing the stability of the entire grinding wheel dressing device 4. In other embodiments, the stepped part 424 can be provided at the front end of the base 42, then the elastic limiting member 46 can be provided only on the front side of the base 42, and only one such member can be provided.
[0045] The grinding wheel dressing device 4 of the present invention can actively activate the clamping module to increase the stability of the dressing module 44 when dressing the grinding wheel 2. This can reduce the direct vibration caused by the dressing body 443 directly contacting the overly rough surface of the grinding wheel 2, and also reduce the indirect vibration transmitted from other parts of the grinding machine. This is beneficial for the dressing module 44 to dress the grinding wheel 2 to a sufficiently round shape. For energy saving and reducing component wear, the clamping module 45 only needs to be activated when the grinding wheel dressing device 4 is grinding the grinding wheel 2, or even only when the vibration amplitude is large.
[0046] refer to Figure 1 The grinding machine of the present invention further includes a first vision measuring device 5 and a second vision measuring device 6 mounted on the frame 3.
[0047] refer to Figure 1The first visual measuring device 5 is used to measure the size of the workpiece and includes a light source module 51, a camera module 52, a first grating ruler 53, a bracket 54, and vertically extending rails 55. The light source module 51 and the camera module 52 are both mounted on their respective brackets 54 and connected to their respective rails 55. The light source module 51 and the camera module 52 are located on the left and right sides of the grinding wheel 2 and can move independently up and down relative to the grinding wheel 2. When the grinding wheel 2 is processing the workpiece, the first visual measuring device 5 remains above the workpiece to avoid debris and dust generated during processing. After the grinding wheel 2 finishes processing, it stops rotating and rises away from the workpiece. The first visual measuring device 5 then descends to the height of the workpiece. The light source module 51 and the camera module 52 are positioned on the left and right sides of the workpiece to achieve backlit image acquisition and measure the workpiece size. The first grating ruler 53 is arranged parallel to the track 55 of the camera module 52, directly measuring the vertical displacement of the support 54. The support 54 and the camera module 52 move synchronously, thereby measuring the vertical displacement of the camera module 52. The worktable 1 has a second grating ruler 11 to measure its horizontal displacement. Even if the size of the workpiece exceeds the field of view of the camera module 52, the camera module 52 can still be calibrated using the first grating ruler 53 and the second grating ruler 11 according to a preset algorithm, and perform multiple image acquisitions on the workpiece to piece together the complete workpiece size.
[0048] The second visual measurement device 6 is fixed behind the grinding wheel 2 and moves up and down with the grinding wheel 2. It is used to acquire images of the worktable 1 and can be used to calibrate the initial positions of the worktable 1 and the grinding wheel 2.
[0049] In summary, the grinding wheel dressing device 4 and the grinding machine of the present invention have the following beneficial effects:
[0050] 1. When dressing the grinding wheel 2, the clamping module is actively activated to increase the stability of the dressing module 44. Specifically, when the driving device 452 drives the pressure part C to reach the preset maximum stroke, the pressure part C applies pressure to the contact surface S3 of the clamping member 454, and the clamping part 4542 of the clamping member 454 applies pressure to the dressing module 44, so that the dressing module 44 is jointly clamped by the clamping member 454 and the side wall 4221 of the through groove 422, thereby increasing the stability of the entire dressing module 44 and reducing its vibration amplitude. This can reduce the direct vibration caused by the dressing body 443 directly contacting the overly rough surface of the grinding wheel 2, and also reduce the indirect vibration transmitted from other parts of the grinding machine, which is beneficial for the dressing module 44 to dress the grinding wheel 2 to a sufficiently round shape.
[0051] 2. An elastic limiting member 46 is installed on the base plate 41 to press down the base 42. The elastic limiting member 46 absorbs the vibration of the entire grinding wheel dressing device 4, increasing the stability of the entire grinding wheel dressing device 4. The elastic part 462 of the elastic limiting member 46 is arranged in an arc shape, which ensures the necessary elasticity while reducing its volume.
[0052] 3. By tilting the contact surface S3, the pressure applied by the pressure-applying part C to the clamping member 454 can be controlled by controlling the travel distance of the pressure-applying part C on the contact surface S3. Setting the angle between the contact surface S3 and the side surface S1 to be greater than or equal to 150° ensures that more than 85% of the thrust generated by the driving device 452 can be converted into pressure from the clamping member 454 on the tool holder 442.
[0053] 4. By setting the pressure part C as a rolling element, the mutual friction between the pressure part C and the clamping element 454 is reduced, thereby reducing the vibration caused by friction, reducing wear, and extending the service life of the parts.
[0054] 5. One end of the moving part 453 is connected to the driving device 452. After bending itself, a part of the moving part 453—that is, the sliding part B—is located below the driving device 452 and is housed in the receiving groove 423 of the base 42. This arrangement makes full use of space, compresses the volume of the entire grinding wheel dressing device 4, and facilitates installation and application.
[0055] 6. The camera module 52 has a first grating ruler 53 that can measure its vertical displacement, and the worktable 1 has a second grating ruler 11 that measures its horizontal displacement. Even if the size of the workpiece exceeds the field of view of the camera module 52, the camera module 52 can still use the first grating ruler 53 and the second grating ruler 11 to perform calibration, acquire multiple images of the workpiece, and piece together the complete workpiece size.
[0056] When this article uses the terms "pushing" or "pressing," it means that a force is transferred between two objects, not that the objects are displaced or deformed. In other words, the use of "pushing" or "pressing" does not limit whether displacement or deformation has occurred. In fact, in the above embodiments, the object being pushed or pressed will not undergo significant displacement or deformation, while in other embodiments, as long as the force transfer is not affected, the object being pushed or pressed may undergo moderate displacement and deformation.
[0057] The above detailed description is only an illustration of preferred embodiments of the present invention and is not intended to limit the patent scope of the present invention. Therefore, all equivalent technical changes made using the description and illustrations of the present invention are included within the patent scope of the present invention.
