Description

Technical Field

[0001] The present application relates to the technical field of scraper rollers, and in particular to a driving mechanism and a control system of a vertical scraper roller. Background Art

[0002] A scraper and roller machine is a machine tool used for internal hole processing, especially suitable for tubular workpieces such as hydraulic cylinders. Scraper and roller machines include vertical scraper and horizontal scraper. The vertical scraper and roller machine is mainly suitable for processing small and medium-sized workpieces. When processing the workpiece, it can make the workpiece have better rigidity, not easy to deform, and can ensure the stability of cutting.

[0003] The existing vertical scraping and rolling machine usually adopts a driving structure in which the upper spindle rotates while the workpiece is fixed when cutting the workpiece. When the spindle gradually moves downward, the tool cuts and rolls the inner wall of the workpiece. Such a driving mechanism requires extremely high coaxiality between the workpiece and the tool. If there is a deviation, the cutting accuracy of the workpiece will be greatly reduced. The clamping of the workpiece only relies on manual clamping and fixing, which cannot guarantee coaxiality and thus cannot guarantee cutting accuracy.

[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0036] like Figure 1-Figure 8 As shown, a driving mechanism of a vertical scraper machine proposed in one embodiment of the present application includes:

[0037] The machine body 1 has a workbench 101 in the machine body 1, a column 102 is fixedly connected to the workbench 101, a lifting assembly 2 is installed on the column 102, a telescopic tool holder 3 is connected to the moving end of the lifting assembly 2, and the lifting assembly 2 can drive the telescopic tool holder 3 to move up and down along the height direction of the column 102, so as to insert the tool into the workpiece to perform reciprocating cutting and rolling operations;

[0038] The rotating clamping member 4 includes a clamp seat 401 rotatably mounted on the workbench 101, a toothed disc 402 is rotatably mounted in the clamp seat 401, a flat threaded disc 403 is constructed on the toothed disc 402, three clamping claws 404 are slidably mounted on the clamp seat 401 toward the center of the circle, the clamping claws 404 are threadedly matched with the flat threaded disc 403, a transmission gear 405 meshing with the toothed disc 402 is rotatably mounted on the outer side of the clamp seat 401, a driving motor 406 is fixedly connected to the bottom of the workbench 101, a linkage gear 407 is fixedly connected to the bottom of the clamp seat 401, and a transmission gear 405 meshing with the toothed disc 402 is fixedly mounted on the output shaft of the driving motor 406. A driving gear 408 meshing with the linkage gear 407 is connected, wherein the axis of the fixture seat 401 is coaxially arranged with the axis of the tool on the telescopic tool seat 3, and the driving motor 406 can drive the fixture seat 401 to rotate through the meshing transmission of the linkage gear 407 and the driving gear 408, thereby driving the workpiece clamped thereon to rotate synchronously, and taking the workpiece as the main rotating party, the workpiece can be driven to rotate during the process of clamping the workpiece by the clamping jaws 404, so as to measure the coaxiality of the workpiece, which can better ensure the coaxiality and improve the subsequent cutting accuracy compared with the static clamping and fixing of the workpiece;

[0039] The limiting driving member 5 comprises an inner gear ring 501 rotatably mounted on the workbench 101, the inner gear ring 501 is sleeved on the outer side of the fixture seat 401 and meshed with the transmission gear 405, and a limiting mechanism 6 for fixing the inner gear ring 501 is installed on the workbench 101, which is mainly used to limit the inner gear ring 501. When the inner gear ring 501 is fixed by the limiting mechanism 6, the rotation of the fixture seat 401 will drive the transmission gear 405 to mesh and roll on the inner gear ring 501, thereby realizing the meshing rotation of the transmission gear 405 and the toothed disk 402, and then the meshing of the clamping jaws 404 and the plane threaded disk 403 is used to realize the clamping jaws 404 to move closer or farther from each other, thereby clamping or releasing the workpiece;

[0040] When the equipment as a whole is working, the workpiece needs to be placed on the clamp seat 401 first, and then the inner gear ring 501 is fixed by the limit mechanism 6 to prevent it from rotating. At this time, the driving motor 406 starts to rotate, and synchronously drives the workpiece placed thereon to rotate together. During this period, the transmission gear 405 meshes and rolls with the inner gear ring 501, the toothed disc 402 meshes and rotates with the transmission gear 405, and the clamping jaw 404 meshes and moves with the flat threaded disc 403, finally realizing the gradual clamping of the workpiece by the clamping jaw 404. During the clamping process, the workpiece rotates accordingly, which can effectively calibrate the coaxiality of the workpiece and the telescopic tool seat 3 to ensure the subsequent cutting accuracy. Moreover, such a driving structure does not require manual clamping of the workpiece, and the operation is more convenient.

[0041] like Figure 2-Figure 3As shown, in some embodiments, the lifting assembly 2 includes a guide rod 201 fixedly connected to the column 102 and a screw rod 202 rotatably installed on the column 102, a moving block 203 is slidably sleeved on the guide rod 201, and the moving block 203 is threadedly sleeved on the screw rod 202, and a rotating motor 204 is installed on the column 102, and the output shaft of the rotating motor 204 is connected to the screw rod 202 through a synchronous belt transmission, and the rotating motor 204 is used to drive the screw rod 202 to rotate, so that the screw rod 202 and the moving block 203 are threadedly matched, thereby driving the moving block 203 to move up and down along the guide rod 201, and then driving the telescopic knife seat 3 to move precisely.

[0042] like Figure 3 , Figure 4 As shown, in some embodiments, the telescopic tool holder 3 includes a moving frame 301 slidably sleeved on the guide rod 201 and the screw rod 202, the bottom of the moving frame 301 is connected to the tool holder 302, and a screw rod 303 with a thread penetrating the upper end of the moving frame 301 is rotatably installed on the moving block 203, and an adjusting motor 304 is fixedly connected to the moving block 203, and the output shaft of the adjusting motor 304 is connected to the screw rod 303 through a pulley transmission. The screw rod 303 is driven to rotate by the adjusting motor 304, so that the screw rod 303 and the moving frame 301 can be matched with each other through the thread, so that the tool holder 302 can be moved in the lifting assembly 2 is driven to move again in a small range. On the one hand, it can increase the moving distance of the tool holder 302. On the other hand, the tool holder 302 can be moved up and down in a small range while moving downward as a whole, so as to perform reciprocating cutting on the workpiece. It is applied to the situation where the roughness inside the workpiece is large to increase the flexibility of the equipment. It should be noted that the tool holder 302 can adopt a fixed structure or a rotating structure. If a rotating structure is adopted, an additional motor and a spindle can be installed to drive the tool holder 302, so as to realize the reverse rotation with the workpiece. The bidirectional rotation can greatly improve the cutting efficiency.

[0043] like Figure 6-Figure 7 As shown, in some embodiments, the clamp seat 401, the toothed disc 402, the flat threaded disc 403 and the middle of the linkage gear 407 are all constructed with interconnected feed holes 7, and the clamp seat 401 is constructed with three sliding grooves 4011 extending from its edge toward its center, and the clamp 404 is slidably installed in the sliding groove 4011, and a telescopic cover 4012 is connected between the two ends of the clamp 404 and the sliding groove 4011, and a protective frame 8 covering the inner gear ring 501 is connected to the workbench 101. The feed hole 7 can make the middle part of the workpiece hollow, so that the cut waste can fall smoothly to the bottom of the workbench 101 to avoid affecting the processing accuracy of the workpiece, and the telescopic cover 4012 and the protective frame 8 are both used to prevent debris and cutting fluid from penetrating therein, thereby ensuring the safety of the structure and improving its service life.

[0044] like Figure 8-Figure 9 As shown, in some embodiments, a plurality of bevel grooves 5011 are constructed along the circumferential array on the outer circumference of the inner gear ring 501, the number of the limiting mechanisms 6 is two and they are symmetrically distributed on both sides of the inner gear ring 501, the limiting mechanisms 6 include a bevel block 601 for plugging into the bevel groove 5011, a mounting frame 602 is fixedly connected to the workbench 101, the bevel block 601 is horizontally slidably installed in the mounting frame 602, and a pushing member 603 for driving the bevel block 601 to telescopically move is connected to the mounting frame 602, when the inner gear ring 501 needs to be fixed, it is only necessary to use the pushing member 603 to push the two bevel blocks 601 to extend into the bevel grooves 5011 on both sides of the inner gear ring 501, and the two sides are relative to fix the inner gear ring 501 therein, so that it cannot rotate, thereby facilitating the rolling engagement of the transmission gear 405 with the inner gear ring 501.

[0045] like Fig. 9 As shown, in some embodiments, the pusher 603 includes a cylinder 6031 fixedly connected to one end of the mounting frame 602, a slide rod 6032 is slidably installed in the cylinder 6031, one end of the slide rod 6032 is connected to the bevel block 601 and the other end is connected to a piston block 6033 slidably installed in the cylinder 6031, and a cylinder pusher 604 for supplying gas to the cylinder 6031 is installed on the body 1. It should be noted that when the clamping jaw 404 clamps the workpiece, the inclined surface of the bevel groove 5011 is pressed against the workpiece. The force is applied to the inclined surface of the bevel block 601, and this force is transmitted to the slide bar 6032 through the inclined surface of the bevel block 601. The cylinder pusher 604 provides air pressure for the column 6031, and the air pressure is used to push the bevel block 601 to extend. Since the air pressure can be changed, the clamping force of the clamp 404 can be controlled by controlling the size of the air pressure, which increases the flexibility of the device and avoids the rigid transmission caused by a single gear transmission, which causes excessive force to be applied to clamp the workpiece and damage the workpiece, thereby increasing safety.

[0046] like Figure 2 and Figure 5As shown, in some embodiments, the cylinder pusher 604 includes a cylinder body 6041 fixedly connected to the column 102, a piston rod 6042 is slidably inserted in the cylinder body 6041, the upper end of the piston rod 6042 is fixedly connected to a cross bar 6043 that movably penetrates the column 102, the other end of the cross bar 6043 is connected to the moving block 203, and the bottom of the cylinder body 6041 is fixedly connected to an air supply pipe 6044, and the other end of the air supply pipe 6044 is connected to the two column barrels 6041 through two shunt pipes 6045. 031 is connected. Before processing the workpiece, the lifting assembly 2 will first push the telescopic tool holder 3 to move to a position close to the workpiece to prepare for subsequent processing. In this process, the moving block 203 can be driven to move downward, thereby pushing the piston rod 6042 to move downward in the cylinder body 6041 through the cross bar 6043, and then squeezing the gas into the column 6031, realizing the air pressure supply to the column 6031, converting the workless movement into driving force, making more effective use of energy, and improving the energy-saving effect of the device.

[0047] like Figure 2 and Figure 5 As shown, in some embodiments, an electromagnetic ventilation valve 9 connected to the outside is connected to one side of the bottom of the cylinder body 6041. The electromagnetic ventilation valve 9 is mainly used to control the air intake and exhaust of the cylinder body 6041. When the piston rod 6042 moves upward, the electromagnetic ventilation valve 9 can be opened to allow the column 6031 to evacuate air while also extracting external gas, thereby ensuring that the air pressure inside and outside the cylinder body 6041 is always balanced, thereby increasing safety. When the piston rod 6042 moves downward, the electromagnetic ventilation valve 9 is closed to facilitate the entry of gas into the column 6031 to provide thrust for the bevel block 601. During this period, the internal air pressure change can be controlled by the intermittent opening and closing of the electromagnetic ventilation valve 9, thereby controlling the thrust size, and then changing the clamping force of the clamp 404 on the workpiece, thereby increasing the flexibility of the device.

[0048] like Fig. 9 As shown, in some embodiments, a support spring 6034 is connected between the piston block 6033 and the inner end of the cylinder 6031. The support spring 6034 can keep the bevel block 601 inserted in the bevel groove 5011 at all times. When the fixture seat 401 flips over, it will drive the transmission gear 405 and the inner gear ring 501 to produce reverse rolling engagement, so that the clamping jaws 404 release the workpiece, which is convenient for disassembly of the workpiece. When the cylinder pusher 604 is not working, the fixture seat 401 rotates forward, the bevel groove 5011 contacts the inclined surface of the bevel block 601, and the bevel block 601 can be pushed to shrink autonomously, thereby avoiding affecting the rotation of the inner gear ring 501 with the fixture seat 401.
