Description

Technical Field

[0001] This application relates to the field of tap grinding technology, and in particular to a tap grinding machine. Background Technology

[0002] In related technologies, tap grinding machines are the core equipment for tap machining, used to grind the threaded portion of taps. A tap grinding machine mainly consists of a tap clamping device for holding the workpiece and a grinding device for grinding the workpiece.

[0003] In operation, the worker first loads the tap into the tap clamping device, then adjusts the grinding spindle assembly relative to the mounting bracket to the required yaw angle. The grinding spindle assembly and mounting bracket are then manually locked together, and machining begins. As use progresses and the wear of the grinding wheel intensifies, the worker removes the tap clamping device, places the dressing wheel in the appropriate position on the grinding machine, and performs a dressing operation. However, this entire manual operation process is not only labor-intensive but also significantly impacts machining accuracy, noticeably increasing the machining error in tap processing. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes a tap-machining grinding machine that can realize automated tap machining and can automatically lock after the grinding device adjusts the runout angle, thereby improving machining efficiency and machining accuracy, and also improving service life through the dressing device.

[0005] A tap-machining grinding machine according to a first aspect of the present invention includes: a tap clamping device, a grinding device, a dressing device, a drive mechanism, and a transfer mechanism. The tap clamping device is used to position a workpiece and drive the workpiece to rotate. The grinding device is disposed on one side of the tap clamping device and includes a mounting frame, a grinding spindle assembly, and a locking mechanism. The grinding spindle assembly is rotatably connected to the mounting frame. The locking mechanism is disposed on the mounting frame and is used to lock / unlock the grinding spindle assembly from the mounting frame. The dressing device is disposed on one side of the grinding device and is used to dress the grinding wheel in the grinding spindle assembly. The drive mechanism is used to drive the grinding device closer to the tap clamping device or the dressing device. The transfer mechanism is disposed on one side of the tap clamping device and is used to load and unload materials onto the tap clamping device.

[0006] The tap grinding machine according to embodiments of the present invention has at least the following beneficial effects: This tap grinding machine includes a tap clamping device, a grinding device, a dressing device, a drive mechanism, and a transfer mechanism. In use, the transfer mechanism removes the pre-processed workpiece from the tap clamping device and simultaneously loads the workpiece to be processed onto the tap clamping device. Subsequently, the grinding device is fed under the drive mechanism and grinds the workpiece in the tap clamping device via the grinding spindle assembly. When the helix angle of the processed workpiece needs to be adjusted according to the workpiece processing requirements, the grinding spindle assembly is rotated relative to the mounting frame, thereby tilting the grinding spindle assembly to the required position. The angle is adjusted, and then the grinding spindle assembly is locked by a locking mechanism to prevent the grinding spindle assembly from wobbling relative to the mounting bracket, which would affect the machining accuracy. In addition, as the grinding device is used, the grinding wheel in the grinding spindle assembly will wear accordingly. Therefore, after the dressing device is moved to the position corresponding to the grinding device by the drive mechanism, the dressing device dresses the grinding spindle assembly, thereby improving the service life of the grinding spindle assembly. Therefore, the tap grinding machine of this application can realize automated tap processing and can automatically lock after the grinding device is adjusted to the yaw angle, thus improving the processing efficiency and processing accuracy, and also improving the service life through the dressing device.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0053] The following is for reference. Figures 1 to 24 This invention describes a tap-machining grinding machine according to an embodiment of the present invention.

[0054] like Figures 1 to 2 As shown, the tap-grinding machine according to an embodiment of the present invention includes: a tap clamping device 100, a grinding device 200, a dressing device 300, a drive mechanism, and a transfer mechanism 500. The tap clamping device 100 is used to position the workpiece 700 and drive the workpiece 700 to rotate. The grinding device 200 is disposed on one side of the tap clamping device 100, and the grinding device 200 includes a mounting bracket 210, a grinding spindle assembly 220, and a locking mechanism. The grinding spindle assembly 220 is rotatably connected to the tap clamping device 100. Mounting bracket 210; locking mechanism is provided on mounting bracket 210 and is used to lock / unlock grinding spindle assembly 220 and mounting bracket 210; dressing device 300 is provided on one side of grinding device 200 and is used to dress grinding tools in grinding spindle assembly 220; drive mechanism is used to drive grinding device 200 close to tap clamping device 100 or dressing device 300; transfer mechanism 500 is provided on one side of tap clamping device 100 and is used to load and unload materials onto tap clamping device 100.

[0055] Understandably, this tap-grinding machine includes a tap clamping device 100, a grinding device 200, a dressing device 300, a drive mechanism, and a transfer mechanism 500. During use, the transfer mechanism 500 removes the pre-processed workpiece 700 from the tap clamping device and simultaneously loads the workpiece 700 to be processed into the tap clamping device 100. Subsequently, the grinding device 200, driven by the drive mechanism, feeds and grinds the workpiece 700 in the tap clamping device 100 via the grinding spindle assembly 220. When the helix angle of the processed workpiece 700 needs to be adjusted according to the processing requirements, the grinding spindle assembly 220 rotates relative to the mounting bracket 210, thereby tilting the grinding spindle assembly 220 to the required angle. Subsequently, the grinding spindle assembly 220 is locked by a locking mechanism to prevent it from wobbling relative to the mounting bracket 210, which would affect machining accuracy. Furthermore, as the grinding device 200 is used, the grinding wheel in the grinding spindle assembly 220 will experience wear. Therefore, after the dressing device 300 is moved to the corresponding position of the grinding device 200 by the drive mechanism, the dressing device 300 dresses the grinding spindle assembly 220, thereby improving its service life. Thus, the tap-processing grinding machine of this application can achieve automated tap processing and can automatically lock after the grinding device 200 adjusts its runout angle, thereby improving processing efficiency and accuracy, and also extending its service life through the dressing device 300.

[0056] Specifically, such as Figure 3 In this embodiment, the grinding spindle assembly 220 is rotatably connected to the mounting frame 210 via the second bearing 212. It should be understood that in some other embodiments, mutually compatible arc-shaped portions and arc-shaped grooves can also be provided on the mounting frame 210 and the grinding spindle assembly 220, thereby enabling the grinding spindle assembly 220 to rotate relative to the mounting frame 210 with its rotation axis fixed.

[0057] Understandably, the locking mechanism includes a first drive assembly 241, a locking handle 243, and a first locking member 242. The first drive assembly 241 drives and connects to the first end of the locking handle 243. The second end of the locking handle 243 is provided with a cam surface 2431 and is hinged to the first end of the first locking member 242. The second end of the first locking member 242 is provided with a pressing and limiting part 2421, which is slidably connected to the grinding spindle assembly 220. When the locking mechanism locks the grinding spindle assembly 220 to the mounting bracket 210, the first drive assembly 241 drives the locking handle 243 to rotate until the cam surface 2431 abuts against the mounting bracket 210, so that the pressing and limiting part 2421 abuts against the grinding spindle assembly 220.

[0058] For example, such as Figures 3 to 6As shown, in this embodiment, the locking mechanism includes a first drive assembly 241, a first locking member 242, and a locking handle 243. The second end of the first locking member 242 is provided with a pressing and limiting part 2421, and the pressing and limiting part 2421 is slidably connected to the grinding spindle assembly 220. The locking assembly 223 also includes a locking handle 243. The second end of the locking handle 243 is rotatably connected to the first end of the first locking member 242. The second end of the locking handle 243 is provided with a cam surface 2431 for abutting against the mounting bracket 210. The distance from the working contour segment 2432 on the cam surface 2431 to the rotation axis of the locking handle 243 gradually changes. At the same time, the first end of the locking handle 243 is driven and connected to the first drive assembly 241, so that the locking handle 243 can rotate under the drive of the first drive assembly 241, thereby changing the area of ​​the working contour segment 2432 that abuts against the mounting bracket 210. When the locking handle 243 rotates, the distance between the area of ​​the working contour section 2432 abutting the mounting bracket 210 and the rotation axis of the locking handle 243 is small, and the distance between the clamping limit part 2421 and the mounting bracket 210 is large, thereby enabling unlocking. The grinding spindle assembly 220 can rotate relative to the mounting bracket 210 to adjust to a suitable angle. When the distance between the area of ​​the working contour section 2432 abutting the mounting bracket 210 and the rotation axis of the locking handle 243 is large, the distance between the clamping limit part 2421 and the mounting bracket 210 is small, thereby enabling the clamping limit part 2421 to press the grinding spindle assembly 220 against the mounting bracket 210, thus achieving locking.

[0059] It should be understood that, in addition to the locking method in the above embodiments, in which the grinding spindle assembly 220 is pressed against the mounting bracket 210 by the locking component 223, in some other embodiments, the locking component 223 may also be a component similar to a car brake pad, which uses friction to hold the grinding spindle assembly 220, thereby achieving locking.

[0060] It is understood that the grinding spindle assembly 220 is provided with a rotating groove 2211, the clamping and limiting part 2421 can slide along the rotating groove 2211, and the rotation axis of the grinding spindle assembly 220 rotating around the mounting frame 210 passes through the center of the rotating groove 2211; the locking handle 243 and the first drive assembly 241 are provided on the side of the mounting frame 210 away from the grinding spindle assembly 220, and the mounting frame 210 is provided with a through hole 211, the first locking member 242 passes through the through hole 211, and the clamping and limiting part 2421 can slide through the rotating groove 2211.

[0061] For example, such as Figures 3 to 8As shown, in this embodiment, the grinding spindle assembly 220 is provided with a rotating groove 2211. The rotation axis of the grinding spindle assembly 220 relative to the mounting bracket 210 is coaxial with the rotating groove 2211. Thus, when the grinding spindle assembly 220 rotates relative to the mounting bracket 210, it can avoid the pressing and limiting part 2421 of the first locking member 242. The first locking member 242 passes through the through hole 211 of the mounting bracket 210. The hole wall of the through hole 211 restricts the first locking member 242 from rotating with the locking handle 243 and can only slide along the through hole 211. Thus, the rotation of the locking handle 243 is transformed into the sliding of the first locking member 242 along the through hole 211, thereby realizing the pressing and limiting part 2421 pressing or releasing the grinding spindle assembly 220. In addition, the locking handle 243 and the first drive assembly 241 are both located on the side of the mounting bracket 210 away from the grinding spindle assembly 220, thereby avoiding interference between the locking handle 243, the first drive assembly 241 and the rotation of the grinding spindle assembly 220.

[0062] Specifically, the grinding spindle assembly 220 includes a fixing plate 221 with a rotating groove 2211, the rotating groove 2211 having an arc-shaped cross-section. The cross-section of the rotating groove 2211 can also be T-shaped, L-shaped, or even conical, as long as it can achieve the clamping and limiting part 2421 clamping the rotating groove 2211 on the side near the mounting bracket 210.

[0063] It should be understood that, in addition to providing a through hole 211 in the mounting bracket 210, in some other embodiments, the mounting bracket 210 may not provide a through hole 211. Instead, the middle part of the first locking member 242 abuts against the lower edge of a plate of the mounting bracket 210. In this way, during the locking process of the locking handle 243, the middle part of the first locking member 242 cannot rotate with the locking handle 243 because it abuts against the lower edge of the plate. As a result, the first locking member 242 can only slide in a direction perpendicular to the fixed plate 221, thereby achieving locking.

[0064] It is understood that the locking mechanism 240 also includes a linkage component 244, which includes a sliding plate 2442 and an adjustment compensation component. The sliding plate 2442 is provided with several receiving slots 24421. The locking handle 243 is inserted into the receiving slots 24421. The sliding plate 2442 is connected to the output end of the first drive component 241 and can slide under the drive of the first drive component 241 to drive the locking handle 243 to rotate through the slot wall of the receiving slot 24421. The adjustment compensation component is provided in the receiving slot 24421 and is used to abut against the locking handle 243. For example, as Figures 5 to 10As shown, in this embodiment, the linkage component 244 further includes a sliding plate 2442 and an adjustment compensation component. The sliding plate 2442 is provided with a plurality of receiving slots 24421, and the locking handle 243 is inserted into the receiving slots 24421. The sliding plate 2442 slides under the drive of the first drive component 241 and drives the locking handle 243 to rotate through the slot wall of the receiving slot 24421, thereby achieving locking.

[0065] However, due to manufacturing errors, the dimensions of the receiving groove 24421 may not meet the usage requirements. When the receiving groove 24421 is too small, the locking handle 243 is locked in the receiving groove 24421, making it difficult to rotate and thus difficult to adjust between locking and loosening. When the receiving groove 24421 is too large, the sliding plate 2442 may not be able to contact the locking handle 243 during sliding and rotate it to the locking position, making it difficult to lock. Therefore, in this embodiment, an adjustment compensation component is also provided. In this case, the receiving groove 24421 can be manufactured to be appropriately larger, and the adjustment compensation component is set in the receiving groove 24421. In this way, the locking handle 243 is located between the groove wall of the receiving groove 24421 and the adjustment compensation component. This allows the adjustment compensation component to compensate for the manufacturing errors of the receiving groove 24421. In use, the locking handle 243 is rotated by adjusting the circumference of the adjustment compensation component and the groove wall of the receiving groove 24421, respectively.

[0066] Specifically, the slide plate 2442 is slidably connected to the mounting bracket 210, and the mounting bracket 210 is provided with a guide rail, so that the slide plate 2442 can slide along the guide rail under the drive of the first drive assembly 241.

[0067] Specifically, the cam surface 2431 is also provided with a base circle segment 2433. The distance from all points on the base circle segment 2433 to the rotation axis of the locking rocker 243 is equal, and the base circle segment 2433 is connected at the position where the distance from the working contour segment 2432 to the rotation axis of the locking rocker 243 is the smallest. The base circle segment 2433 can also compensate for some machining errors of the receiving groove 24421 or deviations in the drive stroke of the first drive assembly 241. In this way, the grinding spindle assembly 220 can be unlocked no matter where the base circle segment 2433 abuts against the mounting bracket 210.

[0068] It is understood that the adjusting compensation component is an eccentric shaft 2441, which is rotatably disposed in a receiving groove 24421. The circumferential surface of the eccentric shaft 2441 and the groove wall of the receiving groove 24421 are respectively used to drive the locking handle 243 to rotate. For example, as Figures 7 to 10As shown, in this embodiment, the adjustment compensation component is set in the form of an eccentric shaft 2441. By rotating the eccentric shaft 2441, the degree to which the circumferential surface of the eccentric shaft 2441 protrudes beyond the receiving groove 24421 is adjusted, thereby adjusting the size of the gap between the circumferential surface of the eccentric shaft 2441 and the groove wall of the receiving groove 24421 for accommodating the locking handle 243, and thus reasonably compensating for the machining error of the receiving groove 24421 according to the actual situation.

[0069] Specifically, such as Figures 6 to 10 The linkage component 244 also includes a third locking member 2443, which connects the eccentric shaft 2441 and the slide plate 2442 and is used to lock the eccentric shaft 2441 to the slide plate 2442.

[0070] It should be understood that the adjustment compensation component can not only be adjusted to the required position before use to compensate for the machining error of the receiving groove 24421, but also, as use progresses, when the wear of the working contour section 2432 of the cam surface 2431 of the locking handle 243 intensifies and the locking effect can no longer be achieved, the degree to which the adjustment compensation component protrudes from the connection position can be adjusted, thereby adjusting the degree of deflection of the locking handle 243, so that the area of ​​the working contour section 2432 further away from the rotation axis of the locking handle 243 can be put into use, thereby extending the service life of the locking mechanism.

[0071] It should be understood that, in addition to the eccentric shaft 2441 structure used in this embodiment, the adjustment compensation component can be configured with any other structure in other embodiments. By replacing the adjustment compensation component, a size-matched adjustment compensation component can be installed in the receiving groove 24421 of the slide plate 2442, thereby meeting the locking and unlocking requirements of this application. In other embodiments, the size of the connection position can be adjusted by adjusting the length of the adjustment compensation component protruding from the receiving groove 24421, thereby meeting the locking and unlocking requirements. For example, the adjustment compensation component can be configured to be threaded into the groove wall of the receiving groove 24421, and the size of the connection position can be adjusted by adjusting the length of the adjustment compensation component screwed out into the receiving groove 24421.

[0072] Specifically, the locking assembly 223 has three sets that are not collinearly distributed, thereby improving the stability of the locking mechanism in locking the grinding spindle assembly 220.

[0073] It is understood that the tap clamping device 100 includes a rotary positioning mechanism 110 and an auxiliary positioning mechanism 120. A clamping position for clamping the workpiece 700 is formed between the rotary positioning mechanism 110 and the auxiliary positioning mechanism 120. The rotary positioning mechanism 110 is used to position the first end of the workpiece 700 and drive the workpiece 700 to rotate, while the auxiliary positioning mechanism 120 is used to position the second end of the workpiece 700. For example, as Figures 12 to 14As shown, in this embodiment, the rotary positioning mechanism 110 and the auxiliary positioning mechanism 120 are arranged opposite to each other and form a clamping position for clamping the workpiece 700. In use, the auxiliary positioning mechanism 120 positions the second end of the workpiece 700, the rotary positioning mechanism 110 positions the first end of the workpiece 700, and drives the workpiece 700 to rotate. Then, under the feed of the grinding device 200, tap processing can be realized.

[0074] It is understood that the abrasive includes a grooving abrasive 2221 and an external cylindrical machining abrasive 2222, which are coaxially arranged; the auxiliary positioning mechanism 120 is provided with a clearance groove 1221 for accommodating the grooving abrasive 2221. For example, as Figures 15 to 17 As shown, in this embodiment, the auxiliary positioning mechanism 120 is provided with a clearance groove 1221. Since this tap clamping device 100 can be used with a grinding device 200 with dual grinding tools, the dual grinding tools can include a grooving grinding tool 2221 and an external diameter machining grinding tool 2222 arranged coaxially. The grooving grinding tool 2221 is used to cut an external thread groove on the workpiece 700, and the external diameter machining grinding tool 2222 is used to perform external diameter machining on the external thread of the workpiece 700. When the grooving grinding tool 2221 is machining the workpiece 700, part of the external diameter machining grinding tool 2222 can be accommodated in the clearance groove 1221, thereby avoiding interference between the external diameter machining grinding tool 2222 and the auxiliary positioning mechanism 120, ensuring the machining of the coaxially arranged dual grinding tools, avoiding frequent clamping of grinding tools affecting the machining efficiency, and also improving the machining accuracy.

[0075] It should be understood that the grooving abrasive 2221 and the external cylindrical machining abrasive 2222 can be the shape of the grinding wheel or the shape of the grinding head.

[0076] Specifically, such as Figure 15 and 18 As shown, the auxiliary positioning mechanism 120 includes a first center 121 and a mounting member 122. One end of the mounting member 122 is provided with a mounting hole 1222 for mounting the first center 121, and the other end is provided with a clearance groove 1221. The first center 121 is detachably connected to the mounting hole 1222 and is used to abut against the second end of the workpiece 700. The rotary positioning mechanism 110 includes a second center 111 and a rotary assembly. The second center 111 is coaxially connected to the rotary assembly and is used to abut against the first end of the positioning workpiece 700. A clamping position is formed between the first center 121 and the second center 111.

[0077] It should be understood that, such as Figure 12As shown, the driving mechanism includes a fourth driving component 420 and a slide. The rotary positioning mechanism 110, the auxiliary positioning mechanism 120 and the fourth driving component 420 are respectively disposed on the slide. The output end of the fourth driving component 420 is connected to the rotary positioning mechanism 110 and is used to drive the rotary positioning mechanism 110 to slide along a third direction to move closer to or away from the auxiliary positioning mechanism 120, thereby achieving clamping or loosening of the workpiece 700.

[0078] It should be understood that, such as Figures 16 to 20 The auxiliary positioning mechanism 120 also includes an adjustment component 123, which is connected to the mounting component 122 and is used to adjust the coaxiality of the first tip 121 and the rotation axis of the rotary positioning mechanism 110. Specifically, the adjustment assembly 123 includes a first adjustment member 1231, a second adjustment member 1232, a base, a first connector, and a second connector. The first tip 121 is mounted on the first adjustment member 1231 via a mounting member 122. The second adjustment member 1232 is mounted on the base. The first connector connects the first adjustment member 1231 and the second adjustment member 1232 and can adjust the position of the first adjustment member 1231 relative to the second adjustment member 1232 in the first direction, which also allows for adjusting the position of the first tip 121 relative to the rotary positioning mechanism 110 in the first direction. The second connector connects the second adjustment member 1232 and the base and can adjust the position of the second adjustment member 1232 relative to the base in the second direction, which also allows for adjusting the position of the first tip 121 relative to the rotary positioning mechanism 110 in the second direction. The first direction, the second direction, and the rotation axis of the rotary positioning mechanism 110 are perpendicular to each other. In other words, the coaxiality of the first tip 121 and the rotary positioning mechanism 110 can be adjusted through the adjustment assembly 123.

[0079] Among them, such as Figures 16 to 20 The first adjusting member 1231 is provided with a strip groove 12312, and the second adjusting member 1232 is provided with a first threaded hole 12321 adapted to the first connecting member, so that the first connecting member can be threadedly connected to the second adjusting member 1232 after passing through the strip groove 12312. The position of the first adjusting member 1231 relative to the second adjusting member 1232 in the first direction can be adjusted by changing the position of the first connecting member in the strip groove 12312. The second adjusting member 1232 is also provided with a waist-shaped hole 12322, and the base is provided with a fourth threaded hole adapted to the second connecting member, so that the second connecting member can be threadedly connected to the base after passing through the waist-shaped hole 12322. The position of the second adjusting member 1232 relative to the base in the second direction can be adjusted by changing the position of the second connecting member relative to the waist-shaped hole 12322.

[0080] It should be understood that, such as Figures 16 to 20As shown, the adjusting assembly 123 also includes a third connecting member. The first adjusting member 1231 is further provided with a third threaded hole 12314 adapted to the third connecting member. The third threaded hole 12314 passes through the first adjusting member 1231. When the first adjusting member 1231 and the second adjusting member 1232 are connected together, the third connecting member can be threaded into the third threaded hole 12314 and abut against the second adjusting member 1232, thereby locking the first adjusting member 1231 and the second adjusting member 1232. Furthermore, by rotating the first adjusting member 1231 relative to the second adjusting member 1232, the coaxiality of the first tip 121 and the rotation axis of the rotary positioning mechanism 110 is adjusted, and the locking of the first adjusting member 1231 and the second adjusting member 1232 is achieved through the third connecting member.

[0081] It should be understood that, such as Figures 16 to 20 The adjusting assembly 123 also includes a fourth connecting member. The first adjusting member 1231 has a second threaded hole 12313 adapted to the fourth connecting member, and the mounting member 122 has a through hole 1224 corresponding to the second threaded hole 12313. Therefore, the fourth connecting member can be threadedly connected to the first adjusting member 1231 after passing through the through hole 1224, thereby realizing the connection and fixation between the mounting member 122 and the first adjusting member 1231.

[0082] It should be understood that, such as Figures 16 to 20 The first tip 121 is mounted on the mounting member 122 through the mounting hole 1222. The arc-shaped part 1223 of the mounting member 122 is embedded in the arc-shaped groove 12311 of the adjustment component 123. The shape of the arc-shaped part 1223 not only meets the positioning of the mounting member 122 and the adjustment component 123, but also facilitates processing. In addition, the arc-shaped surface of the arc-shaped part 1223 is coaxial with the mounting hole 1222, which also facilitates the processing of the mounting hole 1222 for mounting the first tip 121.

[0083] It should be understood that, such as Figure 16 and 22 As shown, the rotary positioning mechanism 110 includes a first rotary drive assembly 113. The output end of the first rotary drive assembly 113 is connected to a rotary assembly, and drives the workpiece 700 to rotate by driving the rotary assembly. The rotary assembly includes a turntable and rotary grippers 112. The rotary grippers 112 and the second tip 111 are both connected to the turntable. The rotary grippers 112 can drive the workpiece 700 to rotate synchronously with the second tip 111 under the drive of the turntable. There are at least two rotary grippers 112, and a receiving position is formed between the multiple rotary grippers 112. The workpiece 700 passes through the receiving position, and since the convergence degree of the multiple rotary grippers 112 is adjustable, the size of the receiving position can be adjusted to adapt to workpieces 700 with different handle sizes.

[0084] Specifically, such as Figure 22 The grinding device 200 includes a second rotary drive assembly 226. The rotation axis of the output end of the second rotary drive assembly 226 is coaxially arranged with the grooving grinding wheel 2221 and the outer cylindrical grinding wheel 2222, thereby realizing the rotary grinding of the grooving grinding wheel 2221 and the outer cylindrical grinding wheel 2222.

[0085] Specifically, such as Figure 22 The grinding device 200 also includes a locking assembly 223 and a first spacer 224. The first spacer 224 is fixed between the grooving grinding wheel 2221 and the external cylindrical grinding wheel 2222. By changing the first spacer 224 of different sizes, the distance between the grooving grinding wheel 2221 and the external cylindrical grinding wheel 2222 can be adjusted to meet the processing requirements of workpieces 700 with different processing requirements. In addition, the locking assembly 223 is used to connect and fix the grooving grinding wheel 2221 and the external cylindrical grinding wheel 2222. The grinding device 200 also includes a second spacer 225. The locking assembly 223 includes a first flange and a second flange. The first flange is connected and fixed to the output end of the second rotary drive assembly 226. The grooving grinding wheel 2221 and the external cylindrical grinding wheel 2222 are locked between the first flange and the second flange. In addition, a second spacer 225 is provided at the end of the first flange and / or the second flange that contacts the grinding wheel, thereby reducing the wear between the grinding wheel and the locking assembly 223. One or more second spacers 225 can be provided.

[0086] It is understood that the grinding apparatus 200 also includes an adjustment mechanism 230, which connects the mounting bracket 210 and the grinding spindle assembly 220, and is used to drive the grinding spindle assembly 220 to rotate relative to the mounting bracket 210. For example, as Figures 3 to 11 As shown, in this embodiment, the grinding device 200 also includes an adjustment component 123, which can adjust the rotation angle of the grinding spindle assembly 220 relative to the mounting bracket 210, thereby improving the degree of automation adjustment of the entire grinding device 200.

[0087] It should be understood that, such as Figures 3 to 11As shown, the adjustment mechanism 230 includes a second drive assembly 231, a transmission assembly 232, and a sliding assembly 233. The transmission assembly 232 includes a lead screw 2321 and a nut 2322. The nut 2322 is threadedly connected to the lead screw 2321. The sliding assembly 233 is connected between the nut 2322 and the grinding spindle assembly 220. The lead screw 2321 is connected to the output end of the second drive assembly 231 and can rotate under the drive of the second drive assembly 231, so that the nut 2322 can drive the grinding spindle assembly 220 to rotate through the sliding assembly 233. The sliding assembly 233 includes a fixing member 2331 and a first bearing 2333. The fixing member 2331 is fixed to the nut 2322 and has a sliding groove 2332. The direction of the sliding groove 2332 is perpendicular to the rotation axis of the grinding spindle assembly 220 along the mounting bracket 210 and the lead screw 2321. The first bearing 2333 is rotatably connected to the grinding spindle assembly 220 and can slide along the sliding groove 2332. In use, the second drive assembly 231 drives the fixing member 2331 to move axially along the lead screw 2321 through the transmission assembly 232, and can drive the first bearing 2333 to slide through the sliding groove 2332 of the fixing member 2331, thereby realizing the rotation of the grinding spindle assembly 220 and adjusting the wrench's yaw angle.

[0088] It is understood that the dressing device 300 includes a dressing spindle assembly 320 and an adjustment mechanism. The dressing spindle assembly 320 includes a dressing abrasive 321. The adjustment mechanism is connected to the dressing spindle assembly 320 and is used to adjust the dressing abrasive 321 to a runout angle adapted to the abrasive. For example, as... Figure 23 As shown, in this embodiment, the adjustment mechanism includes a sixth drive assembly 310 and a transmission mechanism 330. The sixth drive assembly 310 is connected to the dressing spindle assembly 320 through the transmission mechanism 330. The transmission mechanism 330 is a worm gear assembly, thereby adjusting the yaw angle of the dressing spindle assembly 320 through the worm gear assembly. The dressing spindle assembly 320 includes a dressing abrasive 321 for dressing abrasive tools. That is, the adjustment mechanism adjusts the dressing abrasive 321 to an angle that matches the abrasive tool before dressing the abrasive tool.

[0089] It is understood that the drive mechanism includes a third drive assembly 410, a fifth drive assembly 430, and a slide. The tap clamping device 100 and the dressing device 300 are arranged on the slide along a third direction. The output end of the third drive assembly 410 is connected to the grinding device 200 and is used to drive the grinding device 200 to move closer to or away from the slide along a second direction. The output end of the fifth drive assembly 430 is connected to the slide and is used to drive the slide to slide along a third direction, so that the tap clamping device 100 or the dressing device 300 corresponds to the grinding device 200. The second direction and the third direction are both horizontal and perpendicular to each other. For example, as... Figure 1 , Figure 12As shown, in this embodiment, when tapping is performed, the tap clamping device 100 corresponds to the grinding device 200. The third drive component 410 drives the grinding device 200 to approach the slide along the second direction, thereby realizing the feeding of the grinding wheel and thus realizing tapping. With the long-term use of the grinding wheel, when it is necessary to dress the grinding wheel, the fifth drive component 430 drives the slide to slide along the third direction, thereby making the tap clamping device 100 move away from the grinding device 200, and the dressing device 300 corresponds to the grinding device 200. Then, the grinding device 200 approaches the dressing grinding wheel 321 under the drive of the third drive component 410, thereby realizing the dressing of the grinding wheel 321.

The upper end face of the second positioning plate 630 is provided with a square groove 632 for accommodating the handle of the workpiece 700. The first positioning plate 620 is provided with a through circular hole 621. After the workpiece 700 passes through the circular hole 621, it is inserted into the square groove 632, thereby achieving the positioning of the workpiece 700.
