Description

Technical Field

[0001] The invention relates to the technical field of parts processing, in particular to a vertical lathe for assisting the loading and unloading of disc-type parts. Background Art

[0002] Compared to horizontal lathes, where the workpiece is clamped in a chuck, vertical lathes have a vertical spindle axis and a horizontal spindle table, making workpiece clamping and leveling easier and faster. This spindle clamping method reduces the load on the spindle and bearings, allowing vertical lathes to maintain workpiece machining accuracy for a longer period of time.

[0003] Existing vertical lathes are used to process workpieces with large radial dimensions and relatively small axial dimensions, such as turning, milling and grinding the end faces, cylindrical holes and tapered holes of various disks, wheels and sleeves.

[0004] Since iron chips remain on the top surface of the disk after milling and drilling, workers generally wear cloth gloves to protect their hands. Therefore, when picking up the disk and transferring it, the iron chips will stick to their hands, which will cause them to prick their hands and hurt their hands. In addition, the workers have to clean the iron chips when picking up the processed disk, and they have to pick up the disk to be processed and transfer the processed disk. This inevitably wastes time and is not conducive to improving the production efficiency of the assembly line. Summary of the Invention

Furthermore, in the description of the present invention, "several" means two or more, unless otherwise specifically defined.

[0050] See also Figures 1-18 As shown, the present invention provides a vertical lathe for assisting in loading and unloading disc-type parts, comprising a base 100 and a spindle group 110 embedded on the slope of its left end, a longitudinal feed mechanism 120 and a transverse feed mechanism 130 installed on the rear side of the base 100, and a servo turret 140 installed in front of the transverse feed mechanism 130, on which turning tools, milling cutters, grinding rods and other tools can be installed, and the tools on the servo turret 140 perform turning, milling and grinding on the disc-type parts according to the movement set by the machine tool computer system.

[0051] Specifically, the spindle assembly 110 includes a turntable 111, a spindle motor 112 for driving the turntable 111, a plurality of expansion blocks 114 distributed in a circular pattern and at equal intervals on the top surface of the turntable 111, an expansion sleeve 115 placed in the center hole of the turntable 111, and an electric cylinder 116 coaxially connected to the expansion sleeve 115. A boss is provided on the slope of the base 100, and a spindle tube 113 is welded to the bottom surface of the turntable 111 and plugged into the center hole of the boss.

[0052] The spindle motor 112 adopts a 22KW high-power motor with a rated torque of 285N, so that the maximum speed of the turntable 111 can reach 3000rpm, which can increase the chip cutting amount of the machine tool; a number of expansion blocks 114 are surrounded by a circular block and its outer diameter is smaller than the outer diameter of the turntable 111, the expansion sleeve 115 is in the shape of an inverted cone and is connected to the number of expansion blocks 114, the disk piece is sleeved on the outside of the number of expansion blocks 114, and the large diameter end of the expansion sleeve 115 is inserted into the number of expansion blocks 114 to expand and tighten the disk piece.

[0053] Furthermore, a plurality of slots 1111 are provided in a circular shape at equal intervals on the top surface of the turntable 111, and the slots 1111 are inverted T-shaped slots. A block 1141 is welded to the middle of the bottom surface of the expansion block 114, which is engaged with the slots 1111, so as to limit the expansion block 114 from sliding radially on the top surface of the turntable 111; a compression spring 1142 is embedded in the outward end of the block 1141, and the outer port of the slot 1111 is closed. The same structure as that of the block 1141 is used to clamp the outer port of the slot 1111, blocking the outward end of the compression spring 1142, so that the expansion block 114 rebounds and expands, causing it to reset so that the disk can be removed and installed.

[0054] Furthermore, a bearing is provided on the top end of the electric cylinder 116 and the outside of the bearing is connected to the expansion sleeve 115, so that after the expansion sleeve 115 is tightened in the expansion block 114, it can rotate synchronously with the turntable 111 to tighten the disk; the bottom end of the spindle tube 113 and the top end of the output shaft of the spindle motor 112 are both provided with pulleys, and a belt is provided between the two pulleys, so as to start the spindle motor 112 and drive the spindle tube 113 and the turntable 111 to rotate through the transmission of the belt and pulley, so that the disk is milled by the milling cutter of the servo turret 140.

[0055] Specifically, the top surfaces of the left and right ends of the base 100 are inclined surfaces and a chip discharge port is opened in the middle thereof; a loading group 200 for automatically placing the disk on the spindle group 110 is provided on the top surface of the left front end of the base 100, and the loading group 200 includes a loading platform 210, a stepping motor 220 coaxially connected to the middle of the loading platform 210, a pair of supporting rods 230 embedded in the bottom surface of the loading platform 210 and located on both sides of the middle, and two pairs of supporting bars 240 embedded at both ends of the bottom surface of the loading platform 210;

[0056] An elliptical adjustment ring 231 is welded between a pair of supporting rods 230. A directional rod 221 that is clamped to the side of the base 100 is sleeved on the top of the output shaft of the stepping motor 220. The directional rod 221 is slidably connected to the inner arc surface of the adjustment ring 231, so that the directional rod 221 directionally squeezes the adjustment ring 231. A feeding port 211 is opened at both ends of the top surface of the feeding platform 210. A guide groove 214 is symmetrically opened on the bottom surface of the feeding platform 210 and located outside the feeding port 211. The support bar 240 is clamped to the guide groove 214. A pressure block 232 for squeezing the support bar 240 into the feeding port 211 is provided on both sides of the middle part of the supporting rod 230.

[0057] A circular cavity 212 is provided on the bottom of the middle portion of the loading platform 210 . The adjusting ring 231 is rotatably engaged with the circular cavity 212 . Snap-ons 213 are provided between the two sides of the circular cavity 212 and the two loading ports 211 . The supporting rod 230 is engaged with the snap-ons 213 .

[0058] like Figure 8 As shown, the length of the directional rod 221 is the length of the short axis of the adjusting ring 231. When the stepping motor 220 drives the placement table 210 to rotate and place the disc, since the orientation of the directional rod 221 remains unchanged, the adjusting ring 231 rotates synchronously with the turntable 111, and is then squeezed by the directional rod 221, driving the supporting rod 230 to always extend into the placement port 211 toward the outer end of the placement table 210 to place the disc. The other end of the placement table 210 rotates to the top of the turntable 111, and at the same time, the supporting rod 230 at this end retreats into the circular cavity 212, and the disc naturally falls and is sleeved on the outside of the several expansion blocks 114 of the turntable 111 to wait for the disc to be tightened.

[0059] At the same time, the inward end of each pair of guide grooves 214 at the same end is connected to the bayonet 213, and the outward end of each pair of guide grooves 214 at the same end is vertically bent inward and connected to the feeding port 211, and a roller 215 is embedded in the inner bend of the guide groove 214. The support bar 240 is made of 2-2.5mm steel sheet and has plasticity. It is used to guide the support bar 240 to bend into the feeding port 211 and support the pallet together with the support rod 230.

[0060] In addition, a slide groove 233 is provided at the midline of the bottom surface of the supporting rod 230, and a boss is embedded in the top surface of the bayonet 213 to engage with the slide groove 233. A ring is provided at the bottom end of the boss to support the supporting rod 230. A sealing piece is tightly engaged between the bayonet 213 and the lower end of the guide groove 214 to seal the supporting strip 240.

[0061] The inward end of the support bar 240 is slidably connected to the side of the supporting rod 230 and is provided with a folding section 241. When one end of the material placement table 210 rotates above the turntable 111, the supporting rod 230 retreats into the circular cavity 212, and the support bar 240 is not compressed and returns to its original shape, forming a folding section 241, so that the outer end of the support bar 240 retreats completely into the guide groove 214, so that the disk can fall smoothly.

[0062] In addition, a material unloading assembly 300 is provided in the middle of the base 100 to automatically remove and deliver the discs. The material unloading assembly 300 includes a support platform 310 suspended above the middle of the base 100, a servo motor 320 suspended directly below the support platform 310, a material removal rod 330 and an adjustment rod 340 placed on the top surface of the support platform 310;

[0063] A support ring 350 is embedded in the side of the support platform 310 to support the support platform 310 in the air; the inner end of the adjustment rod 340 is coaxially connected to the servo motor 320, and the servo motor 320 is started to drive the adjustment rod 340 to rotate on the top surface of the support platform 310;

[0064] The inner end of the material taking rod 330 is provided with a linkage cover 331, which is D-shaped and has a cavity on its bottom surface. The adjustment rod 340 is slidably connected to the arc surface of the cavity. When the adjustment rod 340 is rotated to the side facing the cavity of the linkage cover 331, Figure 15 When the left and right sides of the material picking rod 330 are limited, the material picking rod 330 is pushed onto the support platform 310 by the adjustment rod 340;

[0065] The top surface of the picking rod 330 is at least aligned with the top surface of the expansion block 114, and the front end of the picking rod 330 is provided with an inclined surface so that the bottom surface of the inserted disk can be lifted to the top surface of the picking rod 330, so that when the picking rod 330 is subsequently retracted, the disk can be taken out from the spindle assembly 110.

[0066] Furthermore, a material rack 150 is provided on the right end slope of the base 100, and the bottom surface of the material rack 150 is flush with the top surface of the material taking rod 330; Figure 5 and Figure 18 When the picking rod 330 rotates 180 degrees and is pushed outward by the adjusting rod 340, the processed disk is shoveled into the top surface of the picking rod 330 by the material rack 150, thereby lifting the disk. After the picking rod 330 retracts and is withdrawn from the material rack 150, the disk tilts forward on the material rack 150 due to its center of gravity, and then slides out of the base 100 and is collected. A conveyor belt can be placed at the right end of the base 100 to catch the disk for transportation and transfer.

[0067] Specifically, a linkage pin 311 is embedded on the top edge of the support platform 310 and toward the right end of the base 100. The linkage pin 311 is located within the rotation range of the adjustment rod 340. A limit pin 312 is symmetrically embedded on the top edge of the support platform 310 and toward the left end of the base 100. The material removal rod 330 is engaged with a pair of limit pins 312 and can slide.

[0068] like Figure 13-16 When the adjusting rod 340 rotates 360 degrees, it drives the picking rod 330 to retreat to the supporting platform 310, and then drives the supporting platform 310 and the picking rod 330 to rotate 180 degrees synchronously toward the right end of the base 100 through the obstruction of the linkage pin 311. Then, the servo motor 320 is started to reverse and drive the adjusting rod 340 to rotate 180 degrees, thereby pushing the picking rod 330 to extend outward, and transporting the disk to the material rack 150. Then, the servo motor 320 is started to rotate forward and drive the adjusting rod 340 to rotate another 360 degrees, thereby driving the supporting platform 310 and the picking rod 330 to reset, so as to wait for the next time to take out the processed disk from the turntable 111.

[0069] It is worth noting that the side surface of the support platform 310 is annular and has a number of positioning grooves 313 at equal intervals. The positioning grooves 313 are V-shaped with rounded corners. Support rods are welded to the front and rear sides of the support ring 350, and the inner ends of the support rods are embedded with positioning blocks 352 that engage with the positioning grooves 313. The positioning blocks 352 are engaged with the positioning grooves 313 to prevent the support platform 310 from rotating due to friction generated by the rotation of the adjustment rod 340.

[0070] The support rods on both sides of the support ring 350 are welded to the inner side surface of the base 100, and the support ring 350 is used to support the support platform 310 in the air; the support platform 310 is sleeved with the output shaft of the servo motor 320 and can rotate, and a groove 351 is provided at the inner end of the support rod for plugging into the positioning block 352, and a spring piece 353 is placed in the groove 351. The spring piece 353 is an elliptical ring structure with an open inner end. The spring piece 353 is made of spring steel in the shape of a thin sheet, which makes it elastic, so that when the positioning block 352 rotates, it can compress the spring piece 353, allowing the positioning block 352 to slide smoothly over the convex surface of the positioning groove 313.

[0071] During processing, the vertical lathe for assisting the loading and unloading of disc-type parts of the present invention places the disc to be processed in the loading port 211 at the outer end of the loading platform 210 and is supported by the supporting rod 230 and a pair of supporting bars 240; the stepping motor 220 is started to drive the loading platform 210 to rotate 180 degrees and rotate to the top of the spindle assembly 110. Since the orientation of the directional rod 221 remains unchanged, the adjusting ring 231 rotates synchronously with the turntable 111 and is then squeezed by the directional rod 221, driving the supporting rod 230 to always extend into the loading port 211 at the outer end of the loading platform 210, so that the disc to be processed loses its support and falls onto the turntable 111, and the disc to be processed is then sleeved outside the expansion blocks 114 of the turntable 111;

[0072] Next, the electric cylinder 116 is activated to drive the expansion sleeve 115 downward and insert it into the expansion blocks 114, thereby expanding and tightening the disc. The spindle motor 112 is then activated to drive the spindle tube 113 and the turntable 111 to rotate via the belt and pulley, so that the disc is milled by the milling cutter of the servo turret 140. Simultaneously, the stepper motor 220 is activated to drive the material placement table 210 to rotate out from above the spindle assembly 110.

[0073] After the disc is processed, Figure 14 and Figure 15 First, the servo motor 320 is started to drive the adjusting rod 340 to rotate 180 degrees clockwise to push the material picking rod 330 to the bottom of the disk and lift it up; then the servo motor 320 is started to drive the adjusting rod 340 to rotate 360 ​​degrees counterclockwise. During this process, the material picking rod 330 is first driven to retreat to the supporting platform 310, and then the supporting platform 310 and the material picking rod 330 are driven to rotate 180 degrees synchronously toward the right end of the base 100 through the obstruction of the linkage pin 311;

[0074] like Figure 16 Then the servo motor 320 is started to drive the adjusting rod 340 to rotate 180 degrees clockwise, and the picking rod 330 is pushed outward to the right end of the base 100, and the disk is transported to the material rack 150.
