Further, as shown in fig. 5, 6, and 7, the anti-winding mechanism 500 includes: three-way base 510, rotating inner barrel 520, outer sleeve 530, and solenoid valve assembly 540. The three-way base 510 is fixedly arranged on the grinding frame body 410, and the three-way base 510 is provided with a liquid flow channel 511; the rotary inner cylinder 520 is arranged on the three-way base 510, the rotary inner cylinder 520 is provided with a connecting channel 521, and the connecting channel 521 is communicated with the liquid flow channel 511; the outer sleeve 530 is movably fitted over the rotary inner cylinder 520, and the outer sleeve 530 has an input passage 531, and the input passage 531 communicates with the connection passage 521. The solenoid valve assembly 540 is installed at a passage port of the liquid flow passage 511 of the three-way base 510, and the solenoid valve assembly 540 communicates with the pipe assembly 440.
During the use, rotary mechanism 600 drives compound mill frame 400 rotatory, and then switches on compound mill frame 400 with the subassembly that the work piece leaned on to grind, for example, the work piece leaned on to grind external grinding component 420 under original state, then compound mill frame 400 will be by internal grinding component 430 and work piece contact after rotatory. The specific working principle of the composite grinding frame 400 will be explained below.
In this embodiment, as shown in fig. 2, the external grinding assembly 420 includes an external grinding wheel 421 and a servo motor 422, the servo motor 421 is installed on the grinding frame body 410, and the external grinding wheel 422 is drivingly connected to the servo motor 421. As shown in fig. 3, the internal grinding assembly 430 includes: the grinding device comprises an inner grinding wheel 431, a grinding wheel shaft 432 and a driving motor 433, wherein the driving motor 433 is installed on the grinding frame body 410, the grinding wheel shaft 432 is in driving connection with the driving motor 433, and the inner grinding wheel 431 is installed on the grinding wheel shaft 432.
The working principle of the composite grinding frame 400 will be described with reference to the embodiment, please refer to fig. 1, fig. 2 and fig. 3 together:
during machining, a workpiece is first clamped on the headstock 210, and assuming that the external grinding assembly 420 is located at a side close to the headstock 210 in an initial state, when grinding an external circle of the workpiece, it is only necessary to drive the sliding table 200 and the headstock 210 thereon to move so that the workpiece approaches and contacts the external grinding wheel 421. At this time, the outer grinding wheel 421 is driven by the servo motor 422 to rotate at a high speed, and further grinds the workpiece in contact therewith. When the inner hole of the workpiece is ground, the positions of the inner grinding assembly 430 and the outer grinding assembly 420 need to be exchanged, that is, the rotating mechanism 600 is started to drive the composite grinding frame 400 to rotate, so that the inner grinding assembly 430 is positioned at one side close to the headstock 210 of the grinding machine; subsequently, the driving motor 433 drives the internal grinding wheel 431 to rotate through the wheel spindle 432, and the grinding head 210 drives the workpiece to approach and contact the internal grinding wheel 431, so that the inner hole of the workpiece can be ground.
Thus, the external grinding component 420 and the internal grinding component 430 are combined together on the grinding frame body 410, and the grinding frame body 410 is driven to rotate by the rotating mechanism 600, so that the switching of the grinding processing modes is completed.
In one embodiment, as shown in fig. 2, the external grinding assembly 420 further includes a grinding wheel guard 423, the grinding wheel guard 423 is mounted on the grinding frame body 410, and the external grinding wheel 421 is partially accommodated in the grinding wheel guard 423. Thus, the external grinding wheel 421 can be protected, and the operator can be prevented from mistakenly touching the external grinding wheel 421 rotating at a high speed.
Further, during grinding, the grinding part needs to be washed by cooling liquid, and the cooling liquid can play a role in cleaning scraps, lubricating, cooling and the like. Because the composite grinding frame 400 of the present invention adopts a rotation mode to perform processing mode switching, in the rotation process of the composite grinding frame 400, the cooling liquid pipeline connected thereon is easy to wind, which is not beneficial to the transportation of the cooling liquid, for this reason, the present invention especially designs the anti-winding mechanism 500, and the following detailed description is made on the anti-winding mechanism 500:
in this embodiment, as shown in fig. 2, the pipe assembly 440 includes an outer grinding cooling pipe 441 and an inner grinding cooling pipe 442, the outer grinding cooling pipe 441 is mounted on the grinding frame body 410 and is close to the outer grinding assembly 420, and the inner grinding cooling pipe 442 is mounted on the grinding frame body 410 and is close to the inner grinding assembly 430.
As shown in fig. 5 and 6, the solenoid valve assembly 540 includes a first solenoid valve 541 and a second solenoid valve 542. The first solenoid valve 541 is installed at one side of the three-way base 510, and the second solenoid valve 542 is installed at the other side of the three-way base 510. As shown in fig. 4, the outer circular grinding cooling pipe 441 and the first solenoid valve 541 are connected by a hose 401, and the inner circular grinding cooling pipe 442 and the second solenoid valve 542 are connected by a hose 401.
The operation of the anti-wind mechanism 500 will be explained with reference to the above structure:
in use, the external cooling fluid is introduced into the input channel 531 of the outer sleeve 530 through the input pipe 501 (as shown in fig. 7), and then sequentially enters the connecting channel 521 of the rotary inner cylinder 520 and the fluid flow channel 511 of the three-way base 510 to reach the solenoid valve assembly 540. When the workpiece is subjected to cylindrical grinding, the first electromagnetic valve 541 is opened, the second electromagnetic valve 542 is closed, and the cooling liquid passes through the first electromagnetic valve 541 and the hose 401, finally reaches the cylindrical grinding cooling pipe 441 and is sprayed out to cool the workpiece being ground; when the workpiece is subjected to internal grinding processing, the second electromagnetic valve 542 is opened, the first electromagnetic valve 541 is closed, and the cooling liquid passes through the second electromagnetic valve 542 and the hose 401 in sequence, finally reaches the internal grinding cooling pipe 442 and is sprayed out to cool the workpiece;
when the grinding mode is switched, the composite grinding jig 400 performs a rotating action, and the winding prevention mechanism 500 mounted thereon also rotates together, but the outer sleeve 530 remains stationary. This is because the outer sleeve 530 is movably fitted to the inner rotary cylinder 520, and the torque of the inner rotary cylinder 520 is not transmitted to the outer sleeve 530, so that the outer sleeve 530 can be kept in the original position. Thus, even if the composite grinding frame 400 rotates, the positions of the outer grinding cooling pipe 441 and the inner grinding cooling pipe 442 are changed, but the input pipe 501 does not need to rotate together with the outer grinding cooling pipe, the input pipe 501 and the outer sleeve 530 can keep the original positions unchanged, and naturally, pipelines such as the input pipe 501, the hose 401 and the like cannot be wound, and stable conveying of cooling liquid can be kept.
In the embodiment, as shown in fig. 3, the anti-winding mechanism 500 further includes a protective housing 550, the protective housing 550 is fixedly mounted on the mill frame body 410, and the three-way base 510, the rotating inner cylinder 520, the outer sleeve 530 and the solenoid valve assembly 540 are all accommodated in the protective housing 550. In this manner, the protective housing 550 may provide protection to the anti-wind mechanism 500.
In one embodiment, as shown in FIG. 6, an outer sleeve 530 is provided with a mounting and fixing plate 532, and the mounting and fixing plate 532 is used for binding the input pipe 501 connected with the outer sleeve 530. Thus, the input pipe 501 is fixedly bound on the mounting and fixing plate 532, so that the vibration of the joint of the outer sleeve 530 and the input pipe 501 can be reduced, and the connection stability of the two is improved.
In summary, the anti-winding rotary compound grinding machine 10 of the present invention can combine the inner grinding assembly 430 and the outer grinding assembly 420 together, so as to reduce the overall size of the grinding machine, and can prevent the coolant pipelines from winding each other, thereby ensuring stable delivery of the coolant.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the utility model. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
