[0029] like Figures 1 to 3 As shown, the utility model provides an automatic loading and unloading structure for small parts of a small machine tool.

[0030] Specifically, by Figure 1-3 Given, including:

[0031] Electric cabinet 1;

[0032] A processing device arranged on one side of the electric cabinet 1 for processing small parts;

[0033] A beam 6 fixedly mounted above the processing equipment;

[0034] Pick-up assembly for picking up and placing small parts;

[0035] The material picking assembly includes a movably mounted installation box on the side wall of the crossbeam 6, a longitudinal axis motor 8 mounted on one side of the installation box, a truss longitudinal axis 11 that can move up and down inside the installation box, a rotatable pneumatic rotating module 14 connected to the bottom end of the truss longitudinal axis 11, and a second soft claw 18 and a first soft claw 19 connected below the pneumatic rotating module 14.

[0036] In the utility model, the feed tray motor 2 is used to drive the screw rod 3 to rotate. During the rotation of the screw rod 3, the feed tray 4 threadedly connected to its outer wall is pushed, so that the feed tray 4 is moved to a position convenient for the placement of parts. After the parts are placed, the feed tray motor 2 is started again to reset the feed tray 4, and then the horizontal axis motor 9 is started to drive the installation box to move along the crossbeam 6. After the installation box moves to the upper end of the feed tray 4, the longitudinal axis motor 8 is started. After the longitudinal axis motor 8 is started, the truss longitudinal axis 11 is driven to rise and fall. During the lifting and lowering process of the truss longitudinal axis 11, the pneumatic rotating module 14 is started to make the pneumatic rotating module 1 4 rotates 180 degrees. After the pneumatic rotating module 14 rotates 180 degrees, the second soft claw 18 and the first soft claw 19 will move downward as a whole. After the second soft claw 18 and the first soft claw 19 move downward, the truss longitudinal axis 11 drops to the right position, and the first soft claw 19 can clamp the part. After the clamping is completed, the longitudinal axis motor 8 runs again to drive the truss longitudinal axis 11 to rise, and then the transverse axis motor 9 starts to drive the installation box and the truss longitudinal axis 11 to move as a whole. During the movement, the first soft claw 19 will pass the part in place detector 10. If the first soft claw 19 successfully clamps the part, then the transverse axis The motor 9 will continue to run. If the part in-position detector 10 does not detect the part, the three-color light on its surface will light up and it will also make a sound to remind the user that there is a problem with the device operation. After the part moves to the top of the processing device, the longitudinal axis motor 8 starts to run and drives the truss longitudinal axis 11 to descend. During the descent, the pneumatic rotating module 14 starts and drives the connecting plate 15 to rotate 180 degrees, so that the second soft claw 18 and the first soft claw 19 are changed to a vertical state. At this time, the part can be docked with the machine tool spindle 12 on the processing device, so that the machine tool spindle 1 2 can process the parts. During the processing, the first soft claw 19 clamps the parts from the top surface of the material tray 4 again through the cooperation of the longitudinal axis motor 8, the transverse axis motor 9 and the pneumatic rotating module 14, and then transmits them to the machine tool spindle 12. The processed parts are taken down by the second soft claw 18, and the parts clamped by the first soft claw 19 are sent into the machine tool spindle 12. The processed parts can be transported to the material tray 4 again, and the unprocessed parts are taken out again. This can be repeated to complete the automatic loading and unloading and processing of multiple small parts.

[0037] By setting up the material picking component, the device can simultaneously realize the picking of parts, send the parts into the machine tool spindle 12, take out and store the processed parts from the machine tool spindle 12, and no human assistance is required for the device during the process, which greatly improves the degree of automation of the device, saves labor, and improves work efficiency. A top movable door 13 is installed above the processing device.

[0038] Furthermore, as a specific implementation of the utility model, the utility model provides an automatic loading and unloading structure for small parts of a small machine tool.

[0039] Specifically, as shown in the electrical cabinet 1, a protective cover 7 is installed below the crossbeam 6 at the top of the installation box. The surface of the protective cover 7 is hollowed out, and a part presence detector 10 is fixedly installed on both sides of the outer wall of the protective cover 7. When the longitudinal axis 11 of the truss is in the initial state, the second flexible claw 18 and the first flexible claw 19 are on the same horizontal plane with the two part presence detectors 10.

[0040] In the utility model, by setting the side wall of the shield 7 to be hollow, the user can observe the transportation process of the parts in real time and respond to emergencies in time. By installing the parts in place detector 10, the surface of the second soft claw 18 and the first soft claw 19 can be detected to determine whether the parts have fallen, so that the parts can be discovered in time after falling.

[0041] Furthermore, as another specific implementation of the utility model, the utility model provides an automatic loading and unloading structure for small parts of a small machine tool.

[0042] Specifically, as shown in the electric cabinet 1, glass observation windows are installed on the front and rear outer walls of the electric cabinet 1, and a movable material tray 4 is installed on the top of the electric cabinet 1.

The bottom end of the material tray 4 is threadedly connected to the outer wall of the screw 3 and can also be slidably mounted on the outer wall of the guide rod.

[0046] In the utility model, the movement of the material tray 4 is limited by setting a limit frame, and one end of the material tray motor 2 is connected to the rotatable screw rod 3, and the bottom end of the material tray 4 is threadedly connected to the outer wall of the screw rod 3. After the user starts the material tray motor 2, the material tray 4 will be pushed by the thread on the surface of the screw rod 3, and then move, which is convenient for taking and placing parts. The existence of the guide rod makes it difficult for the material tray 4 to deviate during the movement.

[0047] Furthermore, as another specific implementation of the utility model, the utility model provides an automatic loading and unloading structure for small parts of a small machine tool.

[0048] Specifically, as shown in the electric cabinet 1, an installation box is movably installed on the side wall of the beam 6, a horizontal axis motor 9 is fixedly installed at the rear end of the installation box, and a guide rail is provided on the side wall of the beam 6 close to the installation box, and the installation box is movably located in the guide rail.

[0049] In the utility model, in order to make the movement of the installation box more stable, a transverse axis motor 9 is provided and the gear connected to the bottom end of the transverse axis motor 9 is meshed with the rack at the top end of the crossbeam 6, so that the installation box will move along the crossbeam 6 after the transverse axis motor 9 is started, and the guide rails provided on the side walls of the crossbeam 6 make the installation box more stable during the movement.

[0050] Furthermore, as another specific implementation of the utility model, the utility model provides an automatic loading and unloading structure for small parts of a small machine tool.

[0051] Specifically, as shown in the screw rod 3, the bottom end of the pneumatic rotating module 14 is fixedly connected to a connecting plate 15, two air pipe joints 16 are fixedly installed on the outer wall of the connecting plate 15, the second flexible claw 18 and the first flexible claw 19 are fixedly installed on the bottom end of the outer wall of the connecting plate 15, and an air exhaust hole 17 is opened between the second flexible claw 18 and the first flexible claw 19.

[0052] In the utility model, by setting a connecting plate 15 and setting a second flexible claw 18 and a first flexible claw 19 fixedly installed on the outer wall of the connecting plate 15, the pneumatic rotating module 14 can drive the second flexible claw 18 and the first flexible claw 19 to move together after rotating, thereby achieving the purpose of changing the angle of the second flexible claw 18 and the first flexible claw 19, and the debris on the surface of the machined part can be blown away by setting the blowing exhaust hole 17.

[0053] Working principle: Use the tray motor 2 to drive the screw rod 3 to rotate. During the rotation of the screw rod 3, the tray 4 threadedly connected to its outer wall will be pushed to move the tray 4 to a position convenient for the placement of parts. After the parts are placed, start the tray motor 2 again to reset the tray 4, and then start the horizontal axis motor 9 to drive the installation box to move along the crossbeam 6. After the installation box moves to the upper end of the tray 4, start the longitudinal axis motor 8. After the longitudinal axis motor 8 is started, it will drive the truss longitudinal axis 11 to rise and fall. During the lifting and lowering of the truss longitudinal axis 11, start the pneumatic rotating module 14 to rotate the pneumatic rotating module 14 The pneumatic rotary module 14 rotates 180 degrees, and after the second and first flexible claws 18 and 19 move downward as a whole, after the second and first flexible claws 18 and 19 move downward, the first flexible claw 19 can clamp the part after the longitudinal axis 11 of the truss drops into place. After the clamping is completed, the longitudinal axis motor 8 runs again to drive the longitudinal axis 11 of the truss to rise, and then the transverse axis motor 9 starts to drive the installation box and the longitudinal axis 11 of the truss to move as a whole. During the movement, the first flexible claw 19 will pass through the part in place detector 10. If the first flexible claw 19 successfully clamps the part, then the transverse axis motor 9 starts to drive the installation box and the longitudinal axis 11 of the truss to move as a whole. The machine 9 will continue to operate. If the part in-position detector 10 does not detect the part, the three-color light on its surface will emit light and it will also make a sound to remind the user that there is a problem with the operation of the device. After the part moves to the top of the processing device, the longitudinal axis motor 8 starts to operate and drives the truss longitudinal axis 11 to descend. During the descent, the pneumatic rotating module 14 starts and drives the connecting plate 15 to rotate 180 degrees, so that the second soft claw 18 and the first soft claw 19 are changed to a vertical state. At this time, the part can be docked with the machine tool spindle 12 on the processing device, so that the machine tool spindle 1 2 can process the parts. During the processing, the first soft claw 19 clamps the parts from the top surface of the material tray 4 again through the cooperation of the longitudinal axis motor 8, the transverse axis motor 9 and the pneumatic rotating module 14, and then transmits them to the machine tool spindle 12. The processed parts are taken down by the second soft claw 18, and the parts clamped by the first soft claw 19 are sent into the machine tool spindle 12.

This can be repeated to complete the automatic loading and unloading and processing of multiple small parts.

[0054] By setting up the material picking component, the device can simultaneously pick up the parts, send the parts into the machine tool spindle 12, and take out and store the processed parts from the machine tool spindle 12. During the process, no human assistance is required to the device, which greatly improves the degree of automation of the device, saves labor, and improves work efficiency.
