Description

Technical Field

[0001] This invention relates to the field of sliding head lathes, and more particularly to a feed system for sliding head lathes. Background Technology

[0002] A sliding-tool lathe is a relatively traditional type of lathe. Its machining operation mainly relies on the movement of the cutting tool to achieve the cutting of the workpiece. During machining, the workpiece is directly mounted on the spindle and rotated by the spindle. The cutting tool is mounted on the tool post and cuts the rotating workpiece by moving the tool post longitudinally, laterally, or obliquely.

[0003] A sliding-tool lathe can perform continuous machining. After a set of workpieces is machined, the cutting tool can be used to cut the machined workpieces. The workpieces will then separate from the stock under gravity. The feeding device inside the device can then move the stock into the device for machining subsequent stock. Although this setup can achieve unloading, the unloading position is relatively close to the chip removal position, so the workpiece will fall directly into the waste chip. If manual unloading is used, the spindle must be stopped first, and then the workpiece must be cut off with the milling cutter inside the device. The overall device is inconvenient when unloading workpieces. Therefore, a feeding system for a sliding-tool lathe is proposed to solve the above problems. Summary of the Invention

[0004] To overcome the above shortcomings, the present invention provides a feed-out system for a feed lathe, which aims to improve the problem in the prior art that "the workpiece falls too close to the chip removal position of the device, making it inconvenient to pick up the workpiece".

The end of the frustoconical sleeve near the transmission block is frustoconical in shape, and the transmission block is L-shaped.

[0017] As a further description of the above technical solution:

[0018] An automatic push rod is installed at the top of the three output shafts of the sliding track. A swing rod is hinged to the outer wall of the output shaft of the automatic push rod. The swing rod is rotatably connected to the top of the three output shafts of the sliding track. The end of the swing rod away from the automatic push rod is slidably connected to the outer wall of the frustum sleeve. The pushing assembly includes a piston sleeve. The piston sleeve is installed on the inner wall of the central shaft. A piston rod is connected to the left end of the piston sleeve.

[0019] As a further description of the above technical solution:

[0020] The upper discharge device includes a sliding rail four, which is installed on the upper surface of the machine.

A second conveyor belt is installed on the upper surface of the inner support. A guide trough is provided on the inner wall of the machine near the rear end.

[0029] The present invention has the following beneficial effects:

[0030] 1. In this invention, by setting up an alignment and feeding device, after processing, the clamping assembly can be aligned with the workpiece by means of sliding rail one, sliding rail two, and sliding rail three. Then, the clamping assembly can be rotated by the drive motor. When the rotation speed of the clamping assembly is the same as the rotation speed of the workpiece, the workpiece can be clamped by the clamping assembly. Then, the cutting tool can be adjusted to separate the workpiece from the end of the bar stock. After that, the workpiece can be moved to a specific bottom end by means of the alignment and feeding device. Then, the pushing assembly can be adjusted to push the workpiece to detach from the left end of the clamping assembly. In this way, the position of the workpiece falling can be controlled. During this process, the spindle can work normally without stopping. The whole device is more convenient when unloading.

[0031] 2. In this invention, by setting a side discharge device, when it is necessary to discharge materials with the help of the main shaft, the automatic push rod three and the automatic push rod two can drive the receiving hopper to move below the main shaft, so that the falling workpieces can be collected. The workpieces will fall directly into the inside of the receiving hopper and move along the guide frame to the top of the conveyor belt two, so that the workpieces can be sent out with the help of the conveyor belt, which can also improve the convenience of material unloading.

[0032] 3. In this invention, by setting up an upper-level material feeding device, when feeding material with the upper-level material feeding device, the pneumatic clamping block can be aligned with the workpiece by means of sliding rail four and sliding rail five. After the workpiece is cut off, the pneumatic clamping block can be used to remove the workpiece. At the same time, when the rotating sleeve rotates 180 degrees, another set of pneumatic clamping blocks can be realigned with the bar stock. In this way, the spindle can be assisted in pulling the material. When continuously processing small parts, continuous feeding and pulling can be achieved with the help of the upper-level material feeding device.

[0033] 4. In this invention, by setting a first transmission belt, the debris generated during processing will fall into the interior of the first transmission belt under the action of gravity, so that the debris can be discharged by the first transmission belt. This allows the debris inside the device to be discharged in a timely manner, facilitating continuous processing. Attached Figure Description

Detailed Implementation

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Reference Figure 1 , Figure 2 and Figure 4 One embodiment of the present invention provides a feed system for a feed lathe, comprising:

[0047] Machine base 1 is used to support the overall device. Machine base 1 is a hollow frame with an enclosed center on all four sides. It can be used to support the overall device. A frame 2 is fixedly connected to the upper surface of machine base 1. The frame 2 can enclose the upper surface of machine base 1 and provide a processing space. A frame 3 is fixedly connected to the inner wall of machine base 1. The frame 3 can be used to support the spindle and install related components.

[0048] The feeding device 8 is installed on the inner wall of the machine base 1 and is used to discharge the workpiece. The feeding device 8 can not only discharge the workpiece, but also discharge the debris generated during the processing of the device, thus realizing continuous processing.

[0049] The upper discharge device 9 is set on the upper surface of the frame 2 and is used to pull out the material. The upper discharge device 9 can not only assist in discharging the workpiece, but also assist the spindle in adjusting the position of the bar stock.

[0050] The side discharge device 7 is set on the outer wall of the frame 3 and is used to receive materials. By setting the side discharge device 7, the workpiece can be guided so that it can move to a specific position.

[0051] The alignment and discharge device 6 is installed on the upper surface of the machine base 1 and is used to pull out materials. The alignment and discharge device 6 includes a sliding rail 1 61, which is installed on the upper surface of the machine base 1 and is parallel to the upper surface of the machine base 1. Its output shaft can move parallel to the machine base 1. A sliding rail 2 62 is installed on the upper surface of the output shaft of the sliding rail 1 61. The output paths of the sliding rail 2 62 and the sliding rail 1 61 are perpendicular to each other. Through the cooperation of the sliding rail 2 62 and the sliding rail 1 61, multi-point adjustment can be realized. A sliding rail 3 63 is installed on the upper surface of the output shaft of the sliding rail 2 62. The sliding rail 3 63 is inclined downwards to facilitate a larger movement trajectory. A clamping assembly is installed on the upper surface of the output shaft of the sliding rail 3 63. Part 64, the upper surface of the sliding track 63 is provided with a mounting bracket for mounting various devices, the clamping assembly 64 is used to clamp the workpiece, and the right surface of the clamping assembly 64 is provided with a pusher assembly 65 for pushing out the workpiece. The clamping assembly 64 includes a central shaft 6410, which is a hollow cylinder with a hollow interior. The central shaft 6410 is rotatably connected to the upper surface of the output shaft of the sliding track 63. A drive motor 66 is mounted on the upper surface of the output shaft of the sliding track 63. The central shaft 6410 and the drive motor 66 are connected by a synchronous belt drive. By starting the drive motor 66, the central shaft 6410 can be driven to rotate. The drive motor 66 is a servo motor, and its speed can be adjusted. By driving the central shaft 6410 to rotate, the central shaft 6410 can be made to rotate synchronously with the workpiece.

[0052] Reference Figures 3-5The clamping assembly 64 also includes a fixing head 641, which is mounted on the left surface of the central shaft 6410. The fixing head 641 can be used to support the internal structure of the central shaft 6410. A closing head 642 is mounted on the left surface of the fixing head 641. The closing head 642 can be used to close the left surface of the fixing head 641 and prevent the internal structure of the central shaft 6410 from detaching from the left end opening of the central shaft 6410. The closing head 642 is a hollow conical sleeve with openings at both the left and right ends, through which the workpiece can pass. The end opening enters the interior of the central shaft 6410. A clamping sleeve 649 for clamping the workpiece is inserted into the inner wall of the fixed head 641. The left end of the clamping sleeve 649 has a notch, so when the outer wall of the clamping sleeve 649 is compressed, the left end of the clamping sleeve 649 deforms inward, thus clamping the workpiece. A compression sleeve 648 for compressing the clamping sleeve 649 is slidably connected to the inner wall of the central shaft 6410. The outer wall of the clamping sleeve 649 is inclined, and the inner wall of the central shaft 6410 is close to the right side of the compression sleeve 648. A transmission sleeve 647 is slidably connected to the surface. When the transmission sleeve 647 moves to the left, it will squeeze the compression sleeve 648, forcing it to move synchronously to the left. The compression sleeve 648 moving to the left will squeeze the clamping sleeve 649, causing its left end opening to contract inward. A frustum-shaped sleeve 645 is slidably connected to the outer wall of the central shaft 6410. A transmission block 646 is rotatably connected to the outer wall of the central shaft 6410. The end of the frustum-shaped sleeve 645 near the transmission block 646 is set in a frustum shape. When the frustum-shaped sleeve 645 moves toward the transmission block 646, it will squeeze... The pressure transmission block 646 forces it to rotate. The transmission block 646 is L-shaped. When the transmission block 646 rotates, it will squeeze the transmission sleeve 647 and force it to move to the left. The pusher assembly 65 includes a piston sleeve 651, which is installed on the inner wall of the central shaft 6410. The piston at the left end of the piston sleeve 651 is connected to a piston rod 652. When it is necessary to discharge the workpiece inside the clamp 649, air can be injected into the piston sleeve 651, which will drive the piston rod 652 to move to the left, thereby pushing the workpiece out.

[0053] Reference Figures 3-5An automatic push rod 643 is mounted on the top of the output shaft of sliding track 3 63. A swing rod 644 for pressing the frustum sleeve 645 is hinged to the outer wall of the output shaft of the automatic push rod 643. The swing rod 644 is rotatably connected to the top of the output shaft of sliding track 3 63. When one end of the swing rod 644 rotates, the other end swings in the opposite direction. The end of the swing rod 644 away from the automatic push rod 643 is slidably connected to the outer wall of the frustum sleeve 645. A pressing wheel is mounted on the end of the swing rod 644 away from the automatic push rod 643, which can press the outer wall of the frustum sleeve 645, forcing the frustum sleeve 645 to rotate. The upper discharge device 9 includes a sliding track 4 91 for supporting the entire upper discharge device 9. The sliding track 4 91 is mounted on the upper surface of the machine base 1. 1. The output shaft is horizontally positioned and can move horizontally. A sliding rail 92 is installed at the front end of the output shaft of sliding rail 4 91. The movement trajectories of the output shafts of sliding rail 4 91 and sliding rail 5 92 are perpendicular to each other. A rotating sleeve 93 is installed on the lower surface of the output shaft of sliding rail 5 92 via a pneumatic rotating shaft. The pneumatic rotating shaft is prior art and can rotate after the air supply device is connected, thus driving the rotating sleeve 93 to rotate. Since the pneumatic rotating shaft is prior art and can be implemented by those skilled in the art, it will not be described in detail in this case. The rotating sleeve 93 is set as a right triangle with its right-angled side perpendicular to the ground. A pneumatic clamping block 94 is installed on the outer wall of the rotating sleeve 93. With this configuration, when the rotating sleeve 93 rotates, it can drive the pneumatic clamping block 94 to switch back and forth between horizontal and vertical states.

[0054] Reference Figures 6-8 The side-discharging device 7 includes a fixing frame 71 for supporting the entire side-discharging device 7. The fixing frame 71 is installed on the outer wall of the frame 3. An automatic push rod 3 74 is installed on the lower surface of the fixing frame 71. The output shaft of the automatic push rod 3 74 can move back and forth parallel to the ground. An automatic push rod 2 72 is installed on the right end of the output shaft of the automatic push rod 3 74. A receiving hopper 73 is installed on the upper surface of the output shaft of the automatic push rod 2 72. The automatic push rod 2 72 is inclined. When the automatic push rod 3 74 pushes out the automatic push rod 2 72, the automatic push rod 2 72 can push the receiving hopper 73 to move it below the main shaft. The dropped workpiece can be caught. The receiving hopper 73 is a conical sleeve with openings at the top and bottom, which makes it easier to catch the material. A guide frame 75 for guiding the material movement is fixedly connected to the lower opening of the receiving hopper 73. The feeding device 8 includes a housing 83, which can support the entire feeding device 8 and protect its internal parts. The housing 83 is inserted into the inner wall of the machine base 1. A conveyor belt 84 for conveying debris is installed on the inner wall of the housing 83. A baffle box 81 for preventing debris from splashing is installed at the right opening of the housing 83.

[0055] Reference Figures 7-9The lower surface of the outer casing 83 is equipped with a movable support 82 for moving the outer casing 83. The lower surface of the movable support 82 is equipped with movable wheels. When the movable support 82 needs to be moved, it can be pulled directly, and the movable wheels will move it. An extension plate 85 is installed at the top of the outer casing 83 near the rear end. A discharge hopper 4 for receiving workpieces is installed on the inner wall of the machine base 1 near the front end. An inner support 86 is set on the inner wall of the machine base 1 near the lower part of the discharge hopper 4. A second conveyor belt 87 is installed on the upper surface of the inner support 86. The material discharged from the lower part of the discharge hopper 4 can fall directly onto the upper surface of the second conveyor belt 87, and the material can be discharged by the second conveyor belt 87. A guide channel 5 for guiding the movement of waste chips is set on the inner wall of the machine base 1 near the rear end. The lower part of the guide channel 5 is aligned with the extension plate 85, which can facilitate the discharge of the debris remaining inside the machine base 1.

[0056] Working principle: After processing, sliding rail 1 61 moves parallel to the upper surface of machine base 1, driving sliding rail 2 62 to adjust laterally, so that the inclined path of sliding rail 3 63 is aligned with the workpiece position. At this time, the drive motor 66 drives the central shaft 6410 to rotate through the synchronous belt, so that the speed of the clamping assembly 64 is synchronized with the speed of the workpiece driven by the spindle. When the clamping assembly 64 is aligned with the workpiece and the speed is consistent, the automatic push rod 1 643 pushes the swing rod 644 to squeeze the frustum sleeve 645. The frustum sleeve 645 drives the transmission sleeve 647 to move to the left through the transmission block 646, and the squeezing sleeve 648 moves to the left accordingly, so that the left end of the inclined clamping sleeve 649 on the outer wall retracts inward, thereby clamping the workpiece. Subsequently, the cutting tool cuts the workpiece from the bar stock. Sliding rail 1 61, sliding rail 2 62, and sliding rail 3 63 move together to transport the workpiece to the designated position. The piston rod 652 of the push assembly 65 extends and pushes the workpiece out from the left end of the fixed head 641 and the closed head 642, realizing precise unloading, and the spindle does not need to stop.

[0057] During side-position material discharge, the automatic push rod 74 moves back and forth along the fixed frame 71, driving the automatic push rod 72 to tilt and extend, causing the receiving hopper 73 to move below the main shaft. When the workpiece is cut, it falls into the receiving hopper 73 under the action of gravity, slides down to the conveyor belt 87 via the conical guide frame 75, and is sent out of the machine platform 1 by the conveyor belt 87. When the upper-position material discharge device 9 is working, the sliding rail 91 and the sliding rail 92 move in coordination, so that the pneumatic clamp 94 is aligned with the workpiece cutting position. After the workpiece is cut, the pneumatic clamp 94 clamps the workpiece and moves it to the unloading area through the sliding rail. At the same time, the rotating sleeve 93 rotates 180° through the pneumatic rotating shaft, and another set of pneumatic clamps 94 rotates to the bar input end, assisting the main shaft in pulling the new bar into the processing position, realizing continuous material discharge and pulling of small parts.

[0058] The outer casing 83 of the feeding device 8 can move flexibly within the machine base 1 via the movable bracket 82 and movable wheels. The first conveyor belt 84 operates continuously, collecting the debris generated during processing. The debris slides down the guide channel 5 to the extension plate 85, and then falls into the first conveyor belt 84 inside the outer casing 83, from which it is sent out of the machine base 1. In addition, the discharge hopper 4 receives the workpieces transported by the alignment discharge device 6 or the side discharge device 7. The workpieces fall from the discharge hopper 4 to the second conveyor belt 87 below, and are transported by the second conveyor belt 87 to the designated collection area, ensuring that the workpieces and debris are discharged separately, avoiding mixing and affecting the material handling efficiency.

[0059] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
