[0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] At present, bearing roller lathes use automatic loading systems for loading, avoiding the low efficiency caused by manual loading. For example, patent CN210412562U discloses an automatic loading and unloading system for a CNC automatic lathe specifically for bearing rollers, which can use a feeding unit to send the roller to the chuck of the lathe. After the chuck clamps the roller, the roller is turned. After the processing is completed, the chuck releases the roller, and the roller falls into the recovery channel and then into the material frame. The inventor found that when using this loading and unloading system, only one end of the roller can be automatically turned. The other end of the roller needs to be manually turned and then manually placed in the loading system to realize the turning of the other end of the roller. This method requires the operator to always observe the processing status of the roller, and then manually turn the roller after the processing is completed, which increases the labor intensity of the operator. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a loading and unloading system for a bearing roller lathe, which can automatically turn the rollers without manual steering, thereby reducing the labor intensity of the operator.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, be constructed and operate in a specific orientation.

[0027] Example 1

[0028] This embodiment provides a loading and unloading system for a bearing roller lathe, such as Figure 1-Figure 2 As shown, the lathe comprises a loading channel 1, a feeding mechanism, a discharge channel, and a workpiece chuck 2. The loading channel 1 is used to load rollers, and the feeding mechanism is used to feed the rollers in the loading channel into the workpiece chuck 2. The workpiece chuck 2 is connected to the lathe's power system and can drive the rollers to rotate along their own axes, thereby turning the rollers with the tool. The discharge channel is used to receive the rollers that fall when the workpiece chuck releases the rollers, and then discharge the rollers. The loading and unloading system also includes a steering mechanism that receives the rollers fed from the discharge channel, rotates them 180°, and then feeds them into the loading channel.

[0029] In this embodiment, the feeding channel 1 is made of channel steel that matches the roller, and its cross-section is U-shaped. The feeding channel 1 is set at a set acute angle to the horizontal plane, and the height of the feed end is greater than the height of the discharge end. The discharge end of the feeding channel 1 is provided with a blocking plate 3 for limiting the sliding of the roller, and the two sides of the discharge end of the feeding channel 1 are provided with discharge holes 4 for the roller to leave the feeding channel.

[0030] like Figure 3 As shown, the feeding mechanism includes a pushing cylinder 5, which is arranged on one side of the discharge end of the feeding channel 1 and is coaxial with the discharge hole 4. The axis of the pushing cylinder 5 is perpendicular to the axis of the feeding channel 1. The cylinder body of the pushing cylinder 5 is fixed, and the end of its piston rod is connected to a push rod 6, which is coaxial with the pushing cylinder 5. In this embodiment, the piston rod of the pushing cylinder 5 drives the push rod 6 to extend from the discharge hole 4 on one side of the feeding channel 1 into the interior of the feeding channel 1, and pushes the roller at the discharge end of the feeding channel 1 out of the discharge hole 4 on the other side to realize discharging.

[0031] A sleeve 7 is provided on the other side of the discharge end of the feeding channel 1, and the open end of the sleeve 7 is arranged toward the side of the feeding channel 1, so that the roller pushed out by the push rod 6 can enter the sleeve 7. The length of the sleeve 7 is less than the length of the roller to be turned, so that after the roller enters the sleeve 7, a portion can be left outside the sleeve 7 to facilitate clamping of the workpiece chuck 2.

[0032] The sleeve 7 is connected to the piston rod of the pressing cylinder 8, and the pressing cylinder 8 is coaxially arranged with the sleeve 7. The cylinder body of the pressing cylinder 8 is fixed on the bracket 9, and the bracket 9 is connected to the second lifting component 10. The second lifting component 10 is arranged above the corresponding area of ​​the workpiece chuck 2. In this embodiment, the second lifting component 10 adopts a lifting cylinder with a vertical axis, the cylinder body of the lifting cylinder is fixed, and the piston rod of the lifting cylinder is connected to the bracket 9.

[0033] The workpiece chuck 2 adopts an existing electric three-jaw chuck, which is used to connect with the power system of the lathe, can drive the roller to rotate around its own axis, and can automatically switch between clamping and loosening the roller.

[0034] The material discharge channel is arranged at a set acute angle with the horizontal plane, and the height of the material feed end of the material discharge channel is higher than the height of the material discharge end thereof.

[0035] In order to avoid the influence of the cutting channel on the movement of the turning tool, the cutting channel includes a fixed channel 11 and a movable channel 12. The fixed channel 11 and the movable channel 12 are both made of channel steel with a U-shaped cross-section. The movable channel 12 is inserted into the fixed channel 11 and is slidably connected to the fixed channel 11.

[0036] A receiving cylinder 13 is fixed to the bottom surface of the fixed channel 11. The axis of the receiving cylinder 13 is arranged parallel to the entire unloading channel. The cylinder body of the receiving cylinder 13 is fixed to the bottom surface of the fixed channel 11. The piston rod of the receiving cylinder 13 is connected to the movable channel 12. The telescopic movement of the receiving cylinder 13 can drive the movable channel 12 to move.

[0037] When the roller turning is completed, the piston rod of the material receiving cylinder 13 drives the movable channel 12 to move, so that one end of the movable channel 12 moves to the bottom of the workpiece chuck 2. After the workpiece chuck 2 releases the roller, the roller can fall into the movable channel 12 by its own gravity. The material receiving cylinder 13 controls the movable channel 12 to retract, and the roller slides along the unloading channel to unload the material.

[0038] The roller entering the feeding channel 1 slides along the feeding channel to the limit baffle, and the lifting cylinder drives the bracket 9 to move, so that the sleeve 7 is aligned with the discharge hole 4 of the feeding channel 1, and the pressing cylinder 8 drives the sleeve 7 to move toward the feeding channel 1 to one side of the feeding channel 1. At this time, the piston rod of the pushing cylinder 5 is extended, and the roller at the discharge end of the feeding channel 1 is pushed into the sleeve 7 through the push rod. Then the push rod 6 is retracted, and the piston rod of the pressing cylinder 8 is retracted and reset, driving the sleeve 7 and the roller to move at the same time.

[0039] The lifting cylinder drives the bracket 9 down until the sleeve 7 is coaxially aligned with the workpiece chuck 2, and the piston rod of the pressing cylinder 8 extends, driving the roller to move through the sleeve 7, so that the end of the roller extends into the clamping area of ​​the workpiece chuck 2, and then the clamping part of the workpiece chuck clamps the roller, the piston rod of the pressing cylinder 8 contracts, the sleeve 7 disengages from the roller, and the lifting cylinder drives the bracket 9 to lift and reset.

[0040] At this point, the workpiece chuck 2 drives the roller to rotate, and the lathe tool feeds according to the set program, turning one end of the roller. After the processing is completed, the piston rod of the material receiving cylinder 13 extends, driving the end of the movable channel 12 to move directly below the workpiece chuck 2. The workpiece chuck 2 releases the roller, and the roller falls into the movable channel 12. The piston rod of the material receiving cylinder 13 retracts, and the roller slides along the material discharge channel to discharge the material.

[0041] In this embodiment, since the material pressing drive component is arranged on the bracket 9 instead of on the bed of the lathe, it will not affect the movement trajectory of the tool. The material pressing drive component does not occupy the space of the lathe in the horizontal direction, which reduces the horizontal size of the lathe and improves the applicability of the lathe to the environment.

[0042] The loading and unloading system of this embodiment also includes a steering mechanism, which is used to rotate the roller 180 degrees after processing one end, and then send it into the loading channel for turning processing on the other end.

[0043] The steering mechanism includes a horizontal moving mechanism 14 fixed to the ground foundation. In this embodiment, the horizontal moving mechanism 14 adopts an existing screw transmission mechanism, including a motor, which is connected to one end of the screw, and the screw is rotatably connected to the base through a bearing seat. A slider is threaded on the screw, and the slider is slidably connected to the base. A first lifting component 15 is provided on the upper surface of the slider. The first lifting component 15 adopts a lifting cylinder or a screw lifting mechanism or an electric lifting rod. In this embodiment, the first lifting component 15 adopts a lifting cylinder, the cylinder body of the lifting cylinder is fixed to the slider, and the end of its piston rod is connected to a mounting plate 16. A rotating platform 17 is provided on the mounting plate 16, and the rotating platform 17 is connected to the material receiving piece.

[0044] The motor drives the lead screw to rotate, which can drive the slider to move, thereby realizing the switching of the corresponding states of the material receiving piece and the loading channel and the unloading channel in the horizontal direction.

[0045] The first lifting component 15 can drive the material receiving piece to move up and down, thereby realizing the switching of the material receiving piece in the vertical direction corresponding to the loading channel 1 and the unloading channel. In order to meet the travel requirements, the first lifting component 15 and the horizontal moving mechanism 14 are installed in a foundation pit opened on the ground foundation.

[0046] The rotary platform 17 can be an existing rotary platform, and its specific structure will not be described in detail here.

[0047] The rotating platform 17 is connected to the material receiving piece through a connecting piece, and the connecting piece includes a connecting plate, which is connected to the rotating part of the rotating platform 17. The center part of the connecting plate is fixed to one end of the connecting rod, and the other end of the connecting rod is connected to the material receiving piece. The rotating platform can drive the material receiving piece to rotate 180° in a single time. The material receiving piece is used to receive the roller falling from the unloading channel, thereby rotating the roller 180°.

[0048] The material receiving member adopts a material receiving plate 18, which is set at a set acute angle with the horizontal plane. The angle between the material receiving plate 18 and the horizontal plane is the same as the angle between the loading channel 1, the unloading channel and the horizontal plane.

[0049] The connecting rod is connected to the center of the bottom surface of the receiving plate 18.

[0050] like Figure 4 As shown, a baffle 19 is provided on one side of the receiving plate 18 along the length direction of the receiving plate. The baffle 19 is provided on the side of the receiving plate 18 with a lower height. The side where the baffle 19 is provided serves as both the receiving end and the discharging end of the receiving plate 18.

[0051] The upper surface of the receiving plate 18 is the receiving surface for receiving the rollers falling from the discharge channel. The upper surface of the receiving plate is provided with two parallel guide plates 20. The guide plates 20 are arranged along the length direction of the receiving plate 18. One end of the guide plate 20 extends to the inner surface of the baffle 19 on one side of the receiving plate 18, and the other end extends to the other side end of the receiving plate 18.

[0052] The distance between the two guide plates 20 matches the length of the roller, and the roller can roll along the material receiving surface of the material receiving plate 18 between the two guide plates 20 .

[0053] The baffle 19 is provided with an opening 21 , the position of the opening 21 matches the area between the two guide plates 20 , and the shape of the opening 21 matches the roller. The roller between the two guide plates 20 can pass through the opening 21 and flow out of the receiving plate 18 .

[0054] The opening 21 is provided with a switch mechanism installed on the baffle, and the switch mechanism is used to control the opening and closing of the opening.

[0055] like Figure 5 As shown, the switching mechanism includes a switching cylinder 22, which is embedded in the cylinder mounting cavity provided in the baffle 19. The piston rod of the switching cylinder 22 is connected to the switching door 23, and can drive the switching door 23 to move, thereby realizing the switching between the open and closed states of the opening 21.

[0056] A photoelectric sensor 24 is provided at the end of the guide plate 20 away from the baffle. The photoelectric sensor 24 includes a transmitting end and a receiving end. The transmitting end is provided on the outside of the end of the guide plate on one side, and the receiving end is provided on the outside of the guide plate on the other side. Accordingly, an opening is provided on the guide plate for light to pass through.

[0057] When the receiving plate 18 is full of rollers, the light emitted by the transmitting end will be blocked, so the photoelectric sensor 24 will send a signal to the control system to prove that the receiving plate 118 is full of rollers to control the steering mechanism to perform the next action.

[0058] The working method of this embodiment is:

[0059] The horizontal moving machine 14 and the first lifting component 15 are controlled in advance to work, so that the receiving plate 18 corresponds to the unloading channel, and the inclination direction of the receiving plate 18 is the same as the inclination direction of the unloading channel. The baffle 19 is set away from the unloading channel. The staff places a group of rollers to be processed on the loading channel 1, and the rollers slide down along the loading channel 1 to the baffle 3. The feeding mechanism drives one of the rollers to move to the workpiece chuck 2, and the workpiece chuck 2 drives the roller to rotate. The tool feeds and performs turning on one end of the roller. After the processing is completed, the roller is unloaded through the unloading channel and slides to the receiving plate 18. The same method is used to perform turning on one end of multiple rollers. The processed rollers slide to the receiving plate and are placed on the receiving plate. The rollers are arranged in sequence on the plate. When the photoelectric sensor 24 detects the roller signal, it proves that the receiving plate 18 is full of rollers. At this time, the horizontal moving mechanism 14 drives the receiving plate 18 to move, and the rotary platform 17 drives the receiving plate 18 to rotate 180 degrees. Then the horizontal moving mechanism 14 and the first lifting component 15 work together to make the receiving plate 18 correspond to the loading channel 1. Since the receiving plate 18 has rotated 180 degrees, the tilt direction of the receiving plate 18 is the same as the tilt direction of the loading channel 1. At this time, the receiving cylinder 22 controls the opening and closing door 23 to open the opening 21 of the baffle 19, and the rollers on the receiving plate 18 slide into the loading channel 1. The other end of the multiple rollers is turned using the same method. The steering mechanism is reset. When the multiple rollers at the other end are processed and fall into the receiving plate again, the opening can be opened and the multiple rollers fall into the placed material frame.

[0060] The loading and unloading system of this embodiment is provided with a steering mechanism, so the roller can be automatically rotated 180 degrees without manual steering of the roller, thereby reducing the labor intensity of the staff.
