Description

Technical Field

[0001] This invention relates to an automated loading and unloading device for a machine tool for processing bushing-type parts. Background Technology

[0002] In mechanical transmission and support structures, bushings, as a common type of sleeve part, are widely used to reduce friction and wear between the shaft and the seat hole, and play a guiding and supporting role.

[0003] Lathes are the main equipment for machining bushing-type parts. The machining process involves two core steps: clamping and positioning the bushing and removing the finished workpiece, namely "loading" and "unloading". Currently, lathe machining of bushing-type parts generally adopts manual loading and unloading. Operators need to manually place the bushing into the fixture and clamp it. After machining, the fixture is released manually and the finished product is removed. This process is repeated. However, this method has obvious drawbacks: manual operation is time-consuming, and the machine tool waiting time is long. Especially for bushing parts with short single-piece machining time, the loading and unloading time accounts for a large proportion, which seriously restricts production efficiency. In addition, operators frequently approach the rotating spindle and cutting area, posing a risk of mechanical injury. Therefore, the existing technology needs to be improved and developed. Summary of the Invention

[0004] To address the shortcomings mentioned above, this invention provides an automated loading and unloading device for a machine tool for processing bushing-type parts.

[0005] To achieve the above objectives, the present invention provides an automated loading and unloading device for a machine tool for processing bushing-type parts, comprising a clamping and rotating assembly, a moving frame assembly, a feeding assembly, a receiving assembly, and a control assembly. A clamping and rotating assembly includes a spindle box and a chuck. The spindle box is fixed above the frame and has a spindle that rotates around its own axis at the output end. The chuck is installed at the front end of the spindle and is used to clamp the bushing and rotate synchronously with the spindle. A mobile frame assembly includes a first mobile base, a first driving mechanism, a second mobile base, and a second driving mechanism. The first mobile base is slidably disposed above the frame and is driven by the first driving mechanism to slide along direction one. The second mobile base is slidably disposed above the first mobile base and is driven by the second driving mechanism to slide along direction two. Directions one and direction two are horizontal and not parallel. The feeding assembly is located above the second movable seat and includes a material rack and a feeding mechanism. The material rack has a cavity for receiving multiple vertically stacked bushings and a discharge hole communicating with the cavity on the lower part of the side wall. The discharge hole corresponds to the position of the bottom bushing. The output end of the feeding mechanism can reciprocate along the axis of the discharge hole. When the material rack is driven to move by the first driving mechanism and the second driving mechanism in cooperation until the discharge hole is close to the chuck, the output end of the feeding mechanism extends into the cavity through the discharge hole to push the bottom bushing out of the material rack and into the clamping mouth of the chuck. A feeding assembly, located inside the spindle box, is used to remove the bushing from the chuck after the chuck is released; A receiving assembly is located above the second movable seat. The receiving assembly is driven by a first drive mechanism and a second drive mechanism to move close to and align with the chuck in order to receive the bearing removed from the chuck. The control component is electrically connected to the clamping rotation component, the moving frame component, the feeding component, and the unloading component.

[0006] Furthermore, the unloading assembly includes a guide sleeve, a pusher, and a drive mechanism. The guide sleeve is limited and installed at the front end of the spindle cavity and has a guide slide for the pusher to slide along the spindle axis. The guide slide is aligned with the clamping port of the chuck. The drive mechanism is connected to the pusher and is used to drive the pusher to push the bushing outward from the chuck along the spindle axis after the chuck is released.

[0007] Furthermore, the pusher head has an axially penetrating mounting cavity and a limiting hole on its side wall. A limiting bolt is screwed into the limiting hole. The driving mechanism is a first spring element. The first spring element is at least partially located in the mounting cavity, and its two ends are respectively connected to the limiting bolt and the end wall of the guide slide away from the chuck. The bushing can be pushed into the clamping port of the chuck by the feeding mechanism and push the pusher head to slide and compress the first spring element to abut against the end wall of the guide slide away from the chuck.

[0008] Furthermore, the end of the guide sleeve furthest from the chuck is connected to a first air pipe, one end of which is connected to the mounting cavity and the other end of which passes through the main shaft and is connected to an external air source.

[0009] Furthermore, the drive mechanism includes a piston sleeve, a piston, a push rod, a second spring element, and a second air pipe. The piston sleeve is located in the inner cavity of the main shaft and connected to the end of the guide sleeve away from the chuck. The piston is slidably and sealed within the piston sleeve. One end of the push rod is fixedly connected to the piston, and the other end passes through the guide sleeve and is fixedly connected to the push head. The second spring element is sleeved outside the push rod, and both ends are connected to the piston and the piston sleeve near the chuck, respectively. One end of the second air pipe is connected to the end of the piston sleeve away from the chuck, and the other end passes through the main shaft and is connected to an external air source. The bushing can be pushed into the clamping port of the chuck by the feeding mechanism and slide along the guide slide until it abuts against the push head.

[0010] Furthermore, the first movable seat is slidably mounted above the frame via a first slide rail and a first slider, with the first slide rail fixed to the frame. The second movable seat is mounted above the first movable seat via a second slide rail and a second slider, with the second slider fixed to the first movable seat. The axis of the first slide rail is parallel to the axis of the main shaft, and the axis of the second slide rail is perpendicular to the axis of the main shaft. Both the first drive mechanism and the second drive mechanism are screw drive mechanisms. One of the screw drive mechanisms is mounted above the frame and is drive-connected to the first movable seat, while the other screw drive mechanism is mounted above the first movable seat and is drive-connected to the second movable seat.

[0011] Furthermore, an adjustment seat is fixedly provided on the second movable seat, and an adjustment groove is provided on the adjustment seat. The axis of the adjustment groove is parallel to the moving direction of the second movable seat. A protrusion is provided below the material rack corresponding to the adjustment groove and slidingly engaging with it. The material rack is abutted and limited by bolts to the top wall of the adjustment seat. The feeding mechanism is located at the end of the material rack away from the chuck and is fixedly connected to the material rack. The feeding mechanism is a pneumatic pushing mechanism.

[0012] Furthermore, it also includes a tool assembly, which includes a tool holder and a lathe tool. The tool holder is fixed above the adjustment seat, and there are multiple lathe tools, each of which is mounted on the tool holder. The lathe tool is driven by a first drive mechanism and a second drive mechanism and moves closer to the chuck to complete the cutting of the bushing.

[0013] Furthermore, the receiving assembly includes a first slide and a second slide. The first slide is fixed to one side of the material rack, and the second slide is fixed to and communicates with the end of the first slide away from the chuck. The second slide is inclined toward the collection box, and the bushing slides into the collection box through the first slide and the second slide.

[0014] Furthermore, it also includes an isolation cover, which covers the frame and all components. The control components include a control module, a start / stop button, and an emergency stop button. The control module integrates a controller and a control panel.

Detailed Implementation

[0017] Example 1: As Figures 1-4 As shown in the figure, an automated loading and unloading device for a machine tool for processing bushing-type parts according to an embodiment of the present invention includes a frame 1000, a clamping rotation assembly 2000, a moving frame assembly 3000, a feeding assembly 4000, an unloading assembly 5000, a receiving assembly 6000, a cutting tool assembly 7000, and a control assembly 8000. The control assembly 8000 is electrically connected to the clamping rotation assembly 2000, the moving frame assembly 3000, the feeding assembly 4000, and the unloading assembly 5000, and is used to control each component to operate according to a set program.

[0018] Furthermore, such as Figures 1-4 As shown, the clamping and rotating assembly 2000 in this embodiment includes a spindle box 2100 and a chuck 2200. The spindle box 2100 is fixed above the frame 1000 and has a spindle that rotates around its own axis at the output end. The chuck 2200 is installed at the front end of the spindle and is used to clamp the bushing and rotate synchronously with the spindle. The chuck 2200 is a power chuck, and the clamping opening of its jaws has an arc surface that matches the outer wall of the bushing to increase the clamping contact area and reduce the clamping deformation of the bushing.

[0019] Furthermore, such as Figures 1-4 As shown, the movable frame assembly 3000 in this embodiment includes a first movable seat 3100, a first driving mechanism 3200, a second movable seat 3300, and a second driving mechanism 3400. The first movable seat 3100 is slidably disposed above the frame 1000 and is driven by the first driving mechanism 3200 to slide along direction one. The second movable seat 3300 is slidably disposed above the first movable seat 3100 and is driven by the second driving mechanism 3400 to slide along direction two. Directions one and two are horizontal and not parallel. Specifically, the first movable seat 3100 is slidably disposed above the frame 1000 through the cooperation of a first slide rail and a first slider. The first slide rail is fixedly connected to the frame 1000. The second movable seat 3300... 3300 is mounted above the first movable seat 3100 via a sliding engagement between the second slide rail and the second slider. The second slider is fixedly connected to the first movable seat 3100. The axis of the first slide rail is parallel to the axis of the main shaft, and the axis of the second slide rail is perpendicular to the axis of the main shaft. The first drive mechanism 3200 and the second drive mechanism 3400 are both screw drive mechanisms. One screw drive mechanism is mounted above the frame 1000 and is connected to the first movable seat 3100 to drive the first movable seat 3100 to move axially along the first slide rail. The other screw drive mechanism is mounted above the first movable seat 3100 and is connected to the second movable seat 3300 to drive the second movable seat 3300 to move axially along the second slide rail.

[0020] Furthermore, such as Figures 1-4 As shown, in this embodiment, the feeding assembly 4000 is located above the second movable seat 3300. It includes a material rack 4100 and a feeding mechanism 4200. The material rack 4100 has a cavity 4101 for vertically stacking multiple bushings and a discharge hole 4102 communicating with the cavity 4101 on the lower part of the side wall. The bushings are arranged sequentially in the cavity 4101 by gravity. The discharge hole 4102 corresponds to the position of the bottom bushing. The output end of the feeding mechanism 4200 can reciprocate along the axis of the discharge hole 4102. When the material rack 4100 is driven by the first driving mechanism 3200 and the second driving mechanism 3400 to move to the discharge hole 4102 and align with the chuck 2200, the output end of the feeding mechanism 4200 extends into the cavity 4101 through the discharge hole 4102 to push the bottom bushing out of the material rack 4100 and into the clamping opening of the chuck 2200, thereby realizing the feeding.

[0021] Furthermore, such as Figures 1-4As shown, in this embodiment, an adjusting seat 3500 is fixedly mounted on the second movable seat 3300. The adjusting seat 3500 is provided with an adjusting groove 3501. The axis of the adjusting groove 3501 is parallel to the moving direction of the second movable seat 3300. A protrusion 4103 is provided below the material rack 4100 corresponding to the adjusting groove 3501. The material rack 4100 cooperates with the adjusting groove 3501 on the adjusting seat 3500 through the protrusion 4103 to realize the interaction between the material rack 4100 and the adjusting seat 3501. The sliding fit of 0, and the material rack 4100 is abutted and limited by the top wall of the adjusting seat 3500 by bolts, thereby determining the relative axial position of the material rack 4100 and the adjusting seat 3500. The feeding mechanism 4200 is located at the end of the material rack 4100 away from the chuck 2200 and is fixedly connected to the material rack 4100. The feeding mechanism 4200 is a pneumatic pushing mechanism. The feeding mechanism 4200 is connected to an external air source, thereby realizing the reciprocating extension and retraction movement of the output end relative to the chuck 2200.

[0022] Furthermore, such as Figures 1-4 As shown, in this embodiment, the unloading assembly 5000 is disposed inside the spindle box 2100 and is used to remove the bushing from the chuck 2200 after the chuck 2200 is released. The unloading assembly 5000 includes a guide sleeve 5100, a pusher head 5200, and a drive mechanism 5300. The guide sleeve 5100 is limited and installed at the front end of the spindle cavity and has a guide slide 5101 inside for the pusher head 5200 to slide along the spindle axis. The guide slide 5101 is aligned with the clamping port of the chuck 2200. The drive mechanism 5300 is connected to the pusher head 5200 and is used to drive the pusher head 5200 to push the bushing outward from the chuck 2200 along the spindle axis after the chuck 2200 is released.

[0023] Furthermore, such as Figure 4 As shown, in this embodiment, the pusher 5200 has an axially penetrating mounting cavity 5201 and a limiting hole 5202 on its side wall. A limiting bolt 5001 is screwed into the limiting hole 5202. The drive mechanism 5300 is a first spring 5301, which is at least partially located in the mounting cavity 5201 and has its two ends connected to the limiting bolt 5001 and the end wall of the guide slide 5101 away from the chuck 2200, respectively. The bushing can be provided by a feeder. The 4200 is pushed into the clamping port of the chuck 2200 and the push head 5200 is pushed to slide and compress the first spring 5301 to abut against the guide slide 5101 away from the end wall of the chuck 2200, so as to achieve axial positioning when the bushing is loaded, so that the chuck 2200 can clamp the bushing. When the chuck 2200 releases the clamping of the bushing, the first spring 5301 provides a compression spring force to push the bushing against the push head 5200 outward, so as to unload the bushing.

[0024] Furthermore, such as Figure 4As shown, in this embodiment, the guide sleeve 5100 is connected to a first air pipe 5002 at one end away from the chuck 2200. One end of the first air pipe 5002 is connected to the mounting cavity 5201, and the other end passes through the main shaft and is connected to an external air source. After the chuck 2200 is released and the bushing is pushed outward by the first spring member 5301, the compressed gas is connected to the clamping port of the chuck 2200 through the first air pipe 5002, the mounting cavity 5201, the guide slide 5101, and blows off the iron filings remaining on the clamping port of the chuck 2200, so as to prevent the iron filings from affecting the chuck 2200 in clamping the next bushing.

[0025] Furthermore, such as Figures 1-4 As shown, in this embodiment, the receiving component 6000 is located above the second movable seat 3300. The receiving component 6000 is driven by the first driving mechanism 3200 and the second driving mechanism 3400 to move close to and align with the chuck 2200 to receive the bearings removed from the chuck 2200. The receiving component 6000 includes a first slide rail 6100 and a second slide rail 6200. The first slide rail 6100 is fixed to one side of the material rack 4100. The second slide rail 6200 is fixed to and communicates with the end of the first slide rail 6100 away from the chuck 2200. The second slide rail 6200 is inclined towards the collection box. Under the combined drive of the first driving mechanism 3200 and the second driving mechanism 3400, the inlet of the first slide rail 6100 is close to and aligned with the chuck 2200 to receive the bearings removed from the chuck 2200. The bushing slides into the collection box through the first slide rail 6100 and the second slide rail 6200 to realize the unloading and collection.

[0026] Furthermore, such as Figures 1-4 As shown, the tool assembly 7000 in this embodiment includes a tool holder 7100 and a turning tool 7200. The tool holder 7100 is fixed above the adjusting seat 3500. There are multiple turning tools 7200, each of which is mounted on the tool holder 7100. The turning tool 7200 is driven by the first driving mechanism 3200 and the second driving mechanism 3400 and moves closer to the chuck 2200 to complete the cutting of the bushing.

[0027] Furthermore, such as Figure 5 As shown, this embodiment also includes an isolation cover 9000, which covers the frame 1000 and all components. The control component 8000 includes a control module 8100, a start / stop button 8200, and an emergency stop button 8300. The control module 8100 integrates a controller and a control panel. The start / stop button 8200 and the emergency stop button 8300 are located on one side of the isolation cover 9000 and are connected to the controller circuit. The device can input parameters through the display screen to set the program actions of each component, and the device's operating status can be displayed on the display screen.

[0028] In practical use, the invention will be described in conjunction with the accompanying drawings for ease of understanding; See Figures 1-5 Under the control of the control component 8000, the first drive mechanism 3200 and the second drive mechanism 3400 cooperate to drive the material rack 4100. The discharge hole 4102 on the material rack 4100 is aligned with the chuck 2200. The bushing is pushed by the feeding mechanism 4200 into the clamping port of the chuck 2200, and pushes the push head 5200 to slide and compress the first spring 5301 until it abuts against the guide slide 5101 away from the end wall of the chuck 2200. The chuck 2200 clamps the bushing, and the output end of the feeding mechanism 4200 returns to the initial position. Each bushing on the frame 4100 moves down one position under the action of gravity; the first drive mechanism 3200 and the second drive mechanism 3400 cooperate to drive, and one of their cutting tools 7200 is aligned with the clamped bearing to perform cutting; after the cutting is completed, the first drive mechanism 3200 and the second drive mechanism 3400 cooperate to drive, the inlet of the first slide rail 6100 is close to the chuck 2200 and aligned, the chuck 2200 releases its clamping, and the bushing slides into the collection box through the first slide rail 6100 and the second slide rail 6200 to realize the unloading and collection.

[0029] Example 2: Figure 6 , Figure 7 As shown, the difference between this embodiment and Embodiment 1 lies in the structure of the drive mechanism 5300. The drive mechanism 5300 in this embodiment includes a piston sleeve (5302), a piston (5303), a push rod (5304), a second spring (5305), and a second air pipe (5306). The piston sleeve (5302) is located in the inner cavity of the main shaft and is connected to the end of the guide sleeve (5100) away from the chuck (2200). The piston (5303) is sealed and slidably connected inside the piston sleeve (5302). One end of the push rod (5304) is fixedly connected to the piston (5303), and the other end passes through the guide sleeve (5100) and is fixedly connected to the push head (5200). The second spring (5305) is sleeved outside the push rod (5304), and both ends are respectively connected to the piston (5303) and the piston sleeve (5306). 302) The end near the chuck (2200) is connected, and one end of the second air pipe (5306) is connected to the end of the piston sleeve (5302) away from the chuck (2200), and the other end passes through the main shaft and is connected to the external air source. When feeding, the bushing can be pushed into the clamping port of the chuck (2200) by the feeding mechanism (4200) and slide along the guide slide (5101) to abut against the push head (5200). At this time, the piston (5303) abuts against the end of the piston sleeve (5302) away from the chuck 2200 to achieve axial positioning when feeding the bushing. When the chuck 2200 releases the clamp, the external air source is ventilated, and the compressed gas acts on the piston 5303 through the second air pipe 5306. The piston 5303 drives the push rod 5304 and the push head 5200 to push the bushing out axially to achieve unloading.
