Description

Technical Field

[0001] This invention relates to the field of parts processing equipment technology, and in particular to a parts processing device for general mechanical equipment manufacturing. Background Technology

[0002] A milling machine is a machine tool used for metal processing. It is mainly used to cut metal on the surface of a workpiece and form a specific shape. The milling machine removes the metal layer on the workpiece by rotating the cutting tool, thereby processing the required shapes such as planes, convex and concave surfaces, and gears. It is one of the common pieces of equipment in the processing of general mechanical parts.

[0003] In actual machining, some parts require vertical drilling on the inclined surface of the workpiece. Because the workpiece is inclined, the milling cutter and the workpiece form an angle. When using the traditional cutting method, a slight outward tilt occurs when the milling hole contacts the workpiece, which affects the drilling accuracy. To address this problem, the commonly used methods are: first, use an end mill to mill a small plane perpendicular to the drill bit axis at the location to be drilled on the inclined surface, and then change to a drill bit to drill, thus avoiding the drill bit slipping when directly starting to drill on the inclined surface; or use a centering drill to position the hole and then change to a drill bit to drill. However, both of these methods require tool changing operations, which affects the machining efficiency.

[0004] Meanwhile, existing milling cutters vibrate during the milling process, causing periodic, fish-scale-like wavy patterns to appear on the groove wall or bottom surface. This not only affects the surface roughness but also reduces the machining accuracy. To avoid this problem, it is necessary to adjust the cutting parameters to reduce the cutting force and avoid the resonance range, or replace the drill bit with a shorter one to reduce vibration. However, these methods also affect the machining efficiency of the workpiece. Therefore, this application provides a general mechanical equipment manufacturing parts processing device to meet the requirements. Summary of the Invention

[0005] The purpose of this invention is to provide a general-purpose mechanical equipment manufacturing parts processing device to solve the above-mentioned problems. By driving the extrusion plate and ball bearings through a pneumatic clamping assembly to form a multi-point fastening support for the milling cutter, the length of the milling cutter suspended under force can be effectively shortened, the end tilting phenomenon when the milling cutter contacts the inclined workpiece can be greatly reduced, and the vibration phenomenon of the milling cutter during milling can also be reduced, thereby reducing the occurrence of fish scale pattern, thus solving the problems mentioned in the background art.

Ball bearings are movably arranged inside the pressing plate.

[0009] Optionally, the bearing ring has an air supply channel inside, and the multiple movable cavities are all connected to the air supply channel. A pneumatic connector is fixedly connected inside the bearing ring, and one end of the pneumatic connector extends into the air supply channel.

[0010] Optionally, the top end of the extrusion plate is provided with an outwardly turned portion, which is integrally formed with the extrusion plate, and the bottom end of the main shaft is provided with a tapered portion, which abuts against the tapered portion.

[0011] Optionally, the adjustment assembly includes a turntable rotatably connected to the bottom of the spindle. The turntable has guide grooves equidistantly arranged inside, and the shaft box has constraint grooves equidistantly arranged inside. A sliding shaft is slidably connected inside the guide groove. The top end of the sliding shaft passes through the constraint groove and is threadedly connected to a fastener. A connector is fixedly connected to the bottom end of the sliding shaft. A pull rod is rotatably connected between the connector and the bearing ring.

[0012] Optionally, a drive assembly is provided inside the axle box. The drive assembly includes a servo motor fixed inside the axle box, a worm gear fixedly connected to the output shaft of the servo motor, a worm wheel rotatably connected inside the axle box, the worm gear meshing with the worm wheel, an arc-shaped groove inside the turntable, a toothed plate fixedly connected to the inner wall of the arc-shaped groove, and a gear fixedly connected to the central shaft of the worm wheel extending into the arc-shaped groove, the gear meshing with the toothed plate.

[0013] Optionally, a spray assembly is provided inside the bearing ring. The spray assembly includes a quick connector fixed inside the bearing ring. An annular water channel is formed inside the bearing ring. One end of the quick connector extends into the annular water channel. Spray holes are equidistantly formed inside the bearing ring, and the spray holes are connected to the annular water channel.

[0014] Optionally, a power assembly is provided inside the axle box. The power assembly includes a drive motor fixed to the top of the axle box. The output end of the drive motor is fixedly connected to a drive pulley. A driven pulley is sleeved on the outside of the main shaft. The driven pulley and the drive pulley are connected by a synchronous belt drive.

[0015] Optionally, the fixed platform is provided with an X-axis linear module that drives the slide to slide longitudinally, the bottom of the worktable is provided with a Y-axis linear module that drives it to slide laterally on the top of the slide, and the column is provided with a Z-axis linear module that drives the axle box to rise and fall.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above solution, the general mechanical equipment manufacturing parts processing device provided in this application drives the extrusion plate and the ball to form a multi-point fastening support for the milling cutter through the pneumatic clamping assembly. This can effectively shorten the length of the milling cutter suspended under force and greatly reduce the end tilting phenomenon when the milling cutter contacts the inclined workpiece. This design can directly realize precise drilling on the inclined surface without milling out a small plane first or using a centering drill to position before changing the tool to drill. This saves multiple tool changes and intermediate processing steps and significantly improves processing efficiency.

[0018] During the milling process, the fastening support structure shortens the length of the stress-bearing part of the milling cutter, which can effectively reduce the vibration force of the milling cutter. It optimizes the surface defects such as fish scale pattern on the groove wall or bottom from the root, greatly improves the flatness and roughness quality of the milled groove surface, and reduces the machining error caused by vibration, ensuring the milling accuracy of parts.

[0019] The balls in the pneumatic clamping assembly can roll synchronously with the rotation of the milling cutter, providing stable support without hindering the rotational cutting operation of the milling cutter. Moreover, when the depth of cutter changes, the height of the bearing ring can be directly adjusted by the drive assembly and the adjustment assembly without stopping the machine, and the milling cutter always maintains dual-point stability during operation.

[0020] The spray assembly, through an annular water channel and spray holes equidistantly arranged on the inner side of the bearing ring, can evenly spray cutting fluid onto the outer side of the milling cutter and the workpiece machining area, achieving all-round lubrication and cooling of the milling cutter and the workpiece. This design effectively reduces friction between the cutting interface, reduces grinding force and frictional heat, not only improving the surface machining quality of the workpiece, but also slowing down milling cutter wear and extending tool life.

[0042] like Figures 1 to 6As shown, an embodiment of the present invention provides a general-purpose mechanical equipment manufacturing parts processing device, including a base 1, a fixed platform 2 fixedly connected to the top of the base 1, a slide 3 slidably connected to the top of the fixed platform 2, a worktable 5 slidably connected to the top of the slide 3, a column 7 fixedly connected to the top of the base 1, a shaft box 9 slidably connected to one side of the column 7, an X-axis linear module 4 for driving the slide 3 to slide longitudinally inside the fixed platform 2, a Y-axis linear module 6 for driving the slide 3 to slide laterally at the bottom of the worktable 5, and a shaft box 9 for driving the slide 3 to slide laterally inside the column 7. The Z-axis linear module 8 of the shaft box 9, which lifts and lowers, drives the slide table 3 longitudinally via the X-axis linear module 4, and the worktable 5 laterally via the Y-axis linear module 6. The Z-axis linear module 8 inside the column 7 synchronously drives the shaft box 9 to complete the lifting and lowering motion. All three are linked and controlled by a PLC controller. The worktable 5 can precisely position the workpiece on a horizontal plane, while the shaft box 9 adjusts the tool height according to processing requirements, enabling the milling cutter 11 to perform various processing operations such as milling and drilling on the workpiece. The spindle 10 is rotatably connected inside the shaft box 9, and a moving... The power assembly includes a drive motor 131 fixed to the top of the shaft box 9. A drive pulley 132 is fixedly connected to the output end of the drive motor 131. A driven pulley 133 is sleeved on the outer side of the spindle 10. The driven pulley 133 and the drive pulley 132 are connected by a synchronous belt 134. The drive motor 131 drives the drive pulley 132 to rotate, and with the cooperation of the synchronous belt 134 and the driven pulley 133, it drives the milling cutter 11 to rotate. This provides core power for milling, drilling, and other operations. A milling cutter is detachably connected inside the spindle 10. The milling cutter 11 has a tool-removing cylinder 12 on top of the spindle box 9. The tool-removing cylinder 12 drives the piston to move by compressed air, realizing the quick replacement of the tool holder and facilitating tool switching during workpiece machining. The outer side of the milling cutter 11 is fitted with a bearing ring 14, and the inner side of the bearing ring 14 is provided with a mounting ring 17. A pneumatic clamping assembly is used to position and support the milling cutter 11 below the spindle 10. The pneumatic clamping assembly is connected to the bearing ring 14 and the mounting ring 17. An adjustment assembly is used to adjust the height of the bearing ring 14. The adjustment assembly is connected to the spindle box 9 and the bearing ring 14.

[0043] In this embodiment, as Figures 4 to 10As shown, the adjustment assembly includes a turntable 151 rotatably connected to the bottom of the main shaft 10. Guide grooves 152 are equidistantly spaced inside the turntable 151. Constraint grooves 153 are equidistantly spaced inside the axle box 9. A sliding shaft 154 is slidably connected inside the guide grooves 152. The top end of the sliding shaft 154 passes through the constraint grooves 153 and is threadedly connected to a fastener 155. The fastener 155 can fix the position of the sliding shaft 154, preventing it from detaching from the guide grooves 152 and constraint grooves 153. A connector 156 is fixedly connected to the bottom end of the sliding shaft 154. The connector 156 is threadedly connected to the sliding shaft 154. A pull rod 157 is rotatably connected between the connector 156 and the bearing ring 14. A drive assembly is provided inside the axle box 9. The drive assembly includes components fixed to the axle box 9. The internal servo motor 161 has a worm gear 162 fixedly connected to its output shaft. A worm wheel 163 is rotatably connected inside the shaft box 9. The worm gear 162 and the worm wheel 163 are meshed together. The turntable 151 has an arc-shaped groove 165 inside. A toothed plate 166 is fixedly connected to the inner wall of the arc-shaped groove 165. The central shaft of the worm wheel 163 extends into the arc-shaped groove 165 and is fixedly connected to a gear 164. The gear 164 meshes with the toothed plate 166. The pneumatic clamping assembly includes movable cavities 181 equidistantly opened inside the mounting ring 17. A slide plate 182 is slidably connected inside each movable cavity 181. A slide rod 183 is fixedly connected to one side of the slide plate 182. One end of the slide rod 183 extends into the inner side of the mounting ring 17 and is fixedly connected to a pressing plate 18. 4. The extrusion plate 184 has a movable ball bearing 185 inside. A drive assembly can rotate the turntable 151. Under the constraint of the guide groove 152, the sliding shaft 154 slides inside the constraint groove 153. Simultaneously, the sliding shaft 154, in conjunction with the connecting piece 156, drives the pull rod 157 to rotate. During this process, multiple pull rods 157 can drive the bearing ring 14 to slide up and down on the outside of the milling cutter 11. At the same time, by filling the air supply channel 186 with high-pressure gas, the gas enters the movable cavity 181 and drives multiple sliding plates 182 to slide synchronously. This causes the sliding plates 182 to move the extrusion plate 184 and the ball bearing 185 closer to the milling cutter 11, thus ensuring that the ball bearing 185 makes tight contact with the milling cutter 11. This, in conjunction with the spindle 10, allows for multiple milling cutter 11 movements. Point-to-point fastening supports shorten the overhang length of the milling cutter 11. Because the force-bearing length of the milling cutter 11 is shortened, the outward tilt of the cutter tip is minimized when it contacts the inclined workpiece, thus improving the accuracy of inclined drilling. Simultaneously, during milling, the shorter force-bearing section reduces the vibration of the milling cutter 11, preventing fish-scale patterns from appearing on the groove wall or bottom and improving the smoothness of the milled groove. It is worth mentioning that the ball bearing 185 can move inside the extrusion plate 184, rolling within it as the milling cutter 11 rotates. This not only does not affect the rotary cutting operation of the milling cutter 11, but also allows for direct adjustment of the height of the bearing ring 14 via the drive assembly and adjustment assembly when the depth of cutter 11 changes, without requiring machine downtime.The milling cutter 11 maintains dual-point stability during operation. An air supply channel 186 is provided inside the bearing ring 14, and multiple movable cavities 181 are connected to the air supply channel 186. A pneumatic connector 187 is fixedly connected inside the bearing ring 14, with one end extending into the air supply channel 186. An outwardly turned portion 1841 is provided at the top of the extrusion plate 184, integrally formed with the extrusion plate 184. A tapered portion is provided at the bottom of the spindle 10, with the outwardly turned portion 1841 abutting against the tapered portion. Under the action of the outwardly turned portion 1841, when the bearing ring 14 moves upward, the extrusion plate 184 fits against the tapered portion at the bottom of the spindle 10. The tapered portion pushes the extrusion plate 184 and slide rod 183 back into the movable cavity 181, thus fully exposing the space inside the mounting ring 17 and preventing multiple extrusion plates 184 from affecting the replacement of the milling cutter 11.

[0044] In this embodiment, as Figure 11 and Figure 12 As shown, a spray assembly is provided inside the bearing ring 14. The spray assembly includes a quick connector 191 fixed inside the bearing ring 14. An annular water channel 192 is opened inside the bearing ring 14. One end of the quick connector 191 extends into the annular water channel 192. Spray holes 193 are equidistantly opened inside the bearing ring 14 and are connected to the annular water channel 192. Through the quick connector 191, it can be connected to external equipment to input cutting fluid into the annular water channel 192. Since the spray holes 193 are inclined, this design allows the cutting fluid to be sprayed obliquely downward. Therefore, the cutting fluid inside the annular water channel 192 can be evenly sprayed onto the outer side of the milling cutter 11 and the workpiece through the spray holes 193, realizing all-round lubrication and cooling of the milling cutter 11 and the workpiece, reducing the friction between the cutting interface, thereby reducing grinding force and frictional heat, improving the durability of the milling cutter 11 and the surface quality of the workpiece.

[0045] Working principle of the invention:

[0046] The workpiece to be processed is fixed on the surface of the worktable 5. The X-axis linear module 4 and the Y-axis linear module 6 are started by the PLC controller: the X-axis linear module 4 drives the slide table 3 to slide longitudinally along the fixed table 2, and the Y-axis linear module 6 drives the worktable 5 to slide laterally along the slide table 3. The two work together to achieve precise positioning of the workpiece in the horizontal plane, so that the part to be processed is aligned directly below the milling cutter 11. The piston is driven by the tool-cutting cylinder 12 to complete the rapid assembly of the milling cutter 11 and the spindle 10. The Z-axis linear module 8 is started, which drives the shaft box 9 to rise and fall along the column 7 to initially adjust the height of the milling cutter 11 so that the bottom of the milling cutter 11 is close to the workpiece machining surface. Then, the height of the bearing ring 14 is adjusted according to the feed requirements of the milling cutter 11. The worm gear 162 is rotated by the servo motor 161. The worm gear 163 drives the gear 164 to rotate. The gear 164, in turn, engages with the gear plate 166 to drive the turntable 151 to rotate. As the turntable 151 rotates, its guide groove 152 drives the sliding shaft 154 to slide along the constraint groove 153. The sliding shaft 154, through the connector 156, drives the tie rod 157 to rotate. Multiple tie rods 157 work together to push the bearing ring 14 up and down along the outside of the milling cutter 11, thereby adjusting the height of the bearing ring 14 and preventing it from affecting the depth of cutter 11. This also separates the outward-facing portion 1841 from the tapered portion on the spindle 10. When milling grooves or drilling holes on an inclined surface is required, high-pressure gas is introduced into the air supply channel 186 within the bearing ring 14 through the pneumatic connector 187. The gas enters multiple movable chambers 186 within the mounting ring 17. Inside cavity 81, the slide plate 182 is pushed to slide along the movable cavity 181. The slide plate 182 drives the slide rod 183 and the extrusion plate 184 to move closer to the milling cutter 11 until the ball bearings 185 in the extrusion plate 184 are in close contact with the surface of the milling cutter 11, forming a multi-point fastening support, shortening the suspended force length of the milling cutter 11. The drive motor 131 is started to drive the drive pulley 132 to rotate, which is transmitted to the driven pulley 133 through the synchronous belt 134, thereby driving the spindle 10 and the milling cutter 11 to rotate at high speed. The PLC controller links the Z-axis linear module 8 to drive the shaft box 9 to slowly descend, so that the milling cutter 11 is fed to the position to be drilled on the inclined surface of the workpiece. Since the ball bearings 185 provide stable support for the milling cutter 11, the outward tilt of the end of the milling cutter 11 when it contacts the inclined surface is effectively suppressed, and direct and precise drilling is achieved. Without the need for additional milling of small planes or centering drill positioning steps, during groove milling, the milling cutter 11 rotates at high speed, and the Z-axis linear module 8 drives the milling cutter 11 to cut into the workpiece to form a groove. At the same time, the X-axis linear module 4 or the Y-axis linear module 6 drives the workpiece to move linearly to complete the groove extension. During this process, the ball bearings 185 of the pneumatic clamping assembly roll synchronously with the rotation of the milling cutter 11, maintaining stable support at two points without hindering the cutting motion. At the same time, shortening the force-bearing length of the milling cutter 11 can significantly reduce vibration and minimize the appearance of fish scale patterns on the groove wall and bottom. If the depth of cutter 11 needs to be changed during processing, there is no need to stop the machine. The height of the bearing ring 14 and the mounting ring 17 can be adjusted again through the drive assembly and the adjustment assembly, and the servo motor 161 can be started.The height of the bearing ring 14 is adjusted in real time by the adjustment component to ensure that the ball bearing 185 is always in contact with the force-bearing part of the milling cutter 11, maintaining support stability. During the cutting process, cutting fluid enters the annular water channel 192 of the bearing ring 14 through the quick connector 191, and is evenly sprayed onto the outside of the milling cutter 11 and the workpiece machining area through the equally spaced nozzles 193, achieving all-round lubrication and cooling of the cutting interface, reducing frictional resistance and frictional heat, improving the surface quality of the machined surface and slowing down the wear of the milling cutter 11. When tool changing is required, the high-pressure gas of the pneumatic clamping component is released, and the bearing ring 14 is moved upward and reset, so that the outward-facing part 1841 is in contact with the tapered part at the bottom of the spindle 10. Then, under the action of extrusion pressure, the extrusion plate 184 is retracted, so that the extrusion plate 184 and the ball bearing 185 are away from the milling cutter 11, thereby expanding the operating space during tool changing. Then, the milling cutter 11 can be quickly changed by using the tool-changing mechanism in conjunction with the tool-removing cylinder 12.
