DETAILED DESCRIPTION

[0059] The specific implementation modes of the present invention are further described in detail with reference to the accompanying drawings.

[0060] See also Figures 1 to 6As shown, an embodiment of the present application provides an auxiliary loading and unloading system for a CNC lathe, comprising: a feeding device 1, a storage device 2, a loading device 4 and a unloading device 5. The feeding device 1 is arranged above the CNC lathe 3. The feeding device 1 includes a plurality of clamping structures 15. The clamping structure 15 is used to grab the workpiece to be processed in the storage device 2 and move it to the top of the corresponding CNC lathe 3, and place the workpiece to be processed on the corresponding loading device 4. The storage device 2 is located below either end of the feeding device 1. The loading device 4 is arranged on the CNC lathe 3. The loading device 4 can be moved in the front and rear direction through a driving member. The loading device 4 is located below the clamping structure 15. The unloading device 5 is connected to the rear side of the loading device 4. The unloading device 5 is used to transport the processed workpiece.

[0061] It should be noted that the material storage device 2 is an open material storage box, the loading device 4 is arranged on the back plate of the CNC lathe 3, and the driving member is a hydraulic cylinder for controlling the loading device 4 to move vertically as a whole; the number of the loading device 4 and the unloading device 5 is flexibly adjusted according to the number of the CNC lathes 3, so that one CNC lathe 3 can load and unload materials through one loading device 4 and one unloading device 5.

[0062] In the above scheme, the feeding device 1 is set up to replace manual feeding to the loading device 4, and the CNC lathe 3 is loaded by the loading device 4, which improves the loading efficiency and reduces the labor intensity. After the workpiece is processed, the loading device 4 cooperates with the unloading device 5 to transport the workpiece and complete the unloading. Compared with the CNC lathe auxiliary loading and unloading system in the prior art, it realizes full automation, simple structure and strong adaptability, can meet diversified processing needs, and further improves the processing accuracy.

[0063] In some possible implementations, see Figures 2 to 4 As shown, the feeding device 4 includes a shell 41 arranged on the CNC lathe 3, and the shell 41 is installed on the back plate of the CNC lathe 3 through a mounting member 48. The mounting member 48 is an elastic telescopic rod. The shell 41 is passed through from top to bottom. A first material guiding mechanism is arranged in the shell 41. The front side of the upper end of the shell 41 is connected to a chute 42. The unloading device 5 is arranged on the rear side of the upper end of the shell 41. Electric push rods 43 are vertically arranged on both sides of the bottom width direction of the shell 41, and material receiving components are arranged at the lower ends of the two electric push rods 43.

[0064] In the above scheme, after the workpiece to be processed enters the shell 41 through the chute 42, the first material guiding mechanism is controlled to start, so that the workpiece to be processed moves downward and falls on the material receiving assembly. At this time, the first material guiding mechanism is controlled to be closed, and the driving member is controlled to start, so that the shell 41 as a whole drives the material receiving assembly to move forward, and the workpiece to be processed on the material receiving assembly is controlled by the electric push rod 43 to be in a coaxial state with the positioning and clamping mechanism of the CNC lathe 3, so that the positioning and clamping mechanism of the CNC lathe 3 can fix the workpiece to be processed.

[0065] In some possible implementations, see Figures 2 to 4 As shown, the first material guiding mechanism includes a conveying belt 45 arranged on both side walls of the shell 41 in the width direction. The conveying belt 45 is driven by a stepping motor 47. A plurality of perpendicular partitions 46 are arranged on the surface of the conveying belt 45. The plurality of partitions 46 are evenly distributed along the circumference of the conveying belt 45.

[0066] In the above scheme, the conveyor belt 45 rotates clockwise. After the workpiece to be processed enters the shell 41 through the chute 42, the conveyor belt 45 rotates, and two adjacent partitions 46 drive a workpiece to be processed downward. When the workpiece to be processed falls on the material receiving assembly, the stepper motor 47 is turned off.

[0067] In some possible implementations, see Figures 2 to 4 As shown, the chute 42 has two side plates and a bottom plate connecting the two side plates. The two side plates are respectively arranged on both sides of the bottom plate in the width direction. The bottom plate is inclined downward from front to back. A gap is left between the partition 46 and the inner wall of the shell 41 to prevent the shell 41 from interfering with the partition 46, so as to facilitate the workpiece to be processed to enter the shell 41, thereby facilitating the two adjacent partitions 46 to limit it.

[0068] In some possible implementations, see Figures 2 to 4 As shown, the material receiving assembly includes two connected material receiving plates 44 , which are respectively located on both sides of the electric push rod 43 . The material receiving plates 44 are arc-shaped structures, and the length of the material receiving plates 44 is equal to the length of the shell 41 .

[0069] In the above scheme, among the two receiving plates 44, the front receiving plate 44 is used to receive the workpiece before processing so as to fix it and process it; the rear receiving plate 44 is used to receive the workpiece after processing and transport it to the unloading device 5 through the conveyor belt 45 for unloading.

[0070] When the processing is completed, when it is necessary to remove the processed workpiece and process the next workpiece, the receiving plate 44 is adjusted by the electric push rod 43 and the driving member so that the rear receiving plate 44 is located below the processed workpiece, which is convenient for receiving the workpiece. After the processed workpiece falls on the rear receiving plate 44, the position of the receiving plate 44 on the front side of the driving member is adjusted by the electric push rod 43 and the driving member so that the workpiece on the front receiving plate 44 is in a coaxial state with the positioning and clamping mechanism of the CNC lathe 3, which is convenient for the positioning and clamping mechanism of the CNC lathe 3 to fix the workpiece to be processed, and then the shell 41 is reset as a whole by the electric push rod 43 and the driving member.

[0071] When conveying the workpiece after processing, first control the electric push rod 43 to start, so that the output end of the electric push rod 43 drives the receiving plate 44 to move upward, so that the distance between the receiving plate 44 and the bottom of the shell 41 is reduced, to prevent the workpiece from falling through the gap between the receiving plate 44 and the bottom of the shell 41, and then control the stepper motor 47 to start, so that the output end of the stepper motor 47 drives the conveyor belt 45 to rotate, and the conveyor belt 45 rotates through the partition 46 to bring the workpiece on the rear receiving plate 44 into the shell 41 and convey it out of the shell 41, so that the workpiece enters the unloading device 5.

[0072] In some possible implementations, see Figure 3 As shown, the feeding device 5 includes a first feeding chute 51 connected to the rear side of the shell 41, and the first feeding chute 51 is connected to a second feeding chute 52 at one end facing away from the shell 41. The second feeding chute 52 is provided with a second material guiding mechanism 53 along its length direction, and the second material guiding mechanism 53 is driven by a first driving motor.

[0073] In the above scheme, the first material chute 51 and the second material chute 52 are both arranged to be inclined downward from front to back, and the lower end of the second material chute 52 is arranged close to the ground. In order to facilitate the collection of processed workpieces, a collection box can be set at the lower end of the second material chute 52 for collection.

[0074] In some possible implementations, see Figure 6 As shown, the feeding device 1 includes a plurality of columns 11, and the plurality of columns 11 are respectively arranged between two adjacent CNC lathes 3. A driving member 12 is provided on the two columns 11 at both ends, and the two driving members 12 are sleeved with the same matching transmission member 13, wherein any driving member 12 is driven by a second driving motor 14, and a plurality of clamping structures 15 are evenly arranged at the lower end of the transmission member 13.

[0075] In the above scheme, multiple columns 11 are fixed to the ground by bolts, the driving member 12 is a sprocket, and the transmission member 13 is a chain; when the chute 42 needs to be fed, the second driving motor 14 is controlled to start, and the output end of the second driving motor 14 rotates to drive the driving member 12 to rotate, the driving member 12 rotates the transmission member 13 to move, and the movement of the transmission member 13 drives multiple clamping structures 15 to move. When each clamping structure 15 moves to the top of the storage device 2 in turn, each clamping structure 15 clamps the workpiece on the storage device 2, and during the clamping process, the second driving motor 14 is turned off.

[0076] In some possible implementations, see Figure 5As shown, the clamping structure 15 includes a telescopic part and a clamping part, the upper end of the telescopic part is connected to the lower end of the transmission member 13, and the clamping part is connected to the lower end of the telescopic part. The clamping part includes a cylindrical body 152, the cylindrical body 152 has a cavity, a first hydraulic rod is arranged in the cavity, and a push rod 155 is connected to the first hydraulic rod. A support plate 154 is arranged at the bottom of the cylindrical body 152, and the lower end of the push rod 155 extends out of the support plate 154. Two claws 156 are symmetrically hinged at the bottom of the support plate 154, and the claws 156 are parallel to the length direction of the chute 42. Two connecting rods 157 are symmetrically hinged at the lower end of the push rod 155, and the end of the connecting rod 157 away from the push rod 155 is hinged to the inner side of the adjacent claw 156.

[0077] In the above scheme, when clamping the workpiece on the storage device 2, the first hydraulic rod is controlled to start, and the output end of the first hydraulic rod drives the push rod 155 to contract. The contraction of the push rod 155 drives the two claws 156 to be relatively hinged through the two connecting rods 157, so that the two claws 156 are close to each other to clamp the workpiece. In order to facilitate clamping of the workpiece, an arc groove can be opened on the inner side of the lower end of the claw 156.

[0078] In some possible implementations, see Figure 5 As shown, the telescopic part includes a fixed plate 151 , the upper end of the fixed plate 151 is arranged at the bottom of the transmission member 13 , at least one second hydraulic rod 153 is arranged at the bottom of the fixed plate 151 , and the output end of the second hydraulic rod 153 is arranged at the upper end of the cylinder 152 .

[0079] In the above scheme, when clamping the workpiece on the storage device 2, if there are fewer workpieces, the claw 156 may not be able to grab the workpiece. By setting the second hydraulic rod 153, the second hydraulic rod 153 is controlled to start. The second hydraulic rod 153 starts to drive the cylinder 152 to move downward through its output end, thereby driving the claw 156 to move downward, so as to facilitate the grabbing of the workpiece.

[0080] This specific embodiment is merely an explanation of the invention and is not a limitation of the invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as they are within the scope of protection of the invention, they are protected by patent law.
