Background Art

[0002] A numerically controlled machine tool is an abbreviation for a computer numerical control machine tool, which is an automated machine tool equipped with a program control system. The control system logically processes and decodes a program having control codes and other symbol instruction specifications, represents them with coded numbers, and can input them into the numerical control device via an information carrier. The numerical control device emits various control signals through arithmetic processing, and controls the operation of the machine tool so as to automatically process parts according to the shape and size required in the drawing.

[0003] Currently, for the supply and discharge of materials of numerically controlled machine tools, material supply using a robot arm and a dedicated pallet is widely adopted, which makes it complicated.

Embodiments for Carrying out the Invention

[0016] Referring to FIGS. 1 to 5, the present invention provides the following technical solutions. An automatic feeding device for a columnar workpiece of a numerically controlled machine tool, comprising A numerically controlled machine tool 1 composed of two and mounted on the floor, A support frame 2 fixed between the two numerically controlled machine tools 1, A material sorting component 3 is fixed to the upper end surface of the support frame 2, A material receiving chamber 4 is fixed at an angle to the upper end surface of the support frame 2 and is located on one side of the material sorting component 3, A material supply component 5 fixed between two numerically controlled machine tools 1 is included, Here, the material supply component 5 is Support for fixing horizontal transfer module 51, a horizontal transfer module 52, a vertical transfer module 53 and a gripping component 54, wherein the horizontal transfer module 52 is Support for fixing horizontal transfer module A vertical transfer module 53 is fixed to the output terminal of the horizontal transfer module 52, and a gripping component 54 is fixed to the output terminal of the vertical transfer module 53.

[0017] In this embodiment, the gripping component 54 is A rotating cylinder 541 is fixed to the output end of the vertical transfer module 53, A gripping cylinder 542 is composed of two parts, which are symmetrically fixed to the output end of the rotating cylinder 541, and the side closer to the material sorting component 3 is the material supply cylinder, The system includes a gripping claw 543 fixed to the output end of the gripping cylinder 542.

[0018] In this embodiment, the material sorting component 3 is A fixed frame 31 with a sliding chamber fixed to its upper end surface at an inclination, It consists of two parts, both fixed to the upper end surface of the support frame 2, and the two inclined frames 32 correspond to the sliding chamber and the material receiving chamber 4, respectively. A material extrusion component 33 is detachably attached to each of the two inclined frames 32, A material sorting block 34 is provided so as to be slidable on the side of the fixed frame 31 closer to the inclined frame 32 by a sliding block, A telescopic cylinder 35 is fixed to the aforementioned fixed frame 31, and its output end is connected to the lower end surface of the material sorting block 34. A sliding plate 36 is slidably provided on the upper end surface of the material sorting block 34, and a pressure spring is provided between it and the material sorting block 34. The set includes an adjustment component 37 fixed to the side of the fixed frame 31 away from the inclined frame 32.

[0019] Furthermore, a visual sensor (not shown) is fixed above the adjustment component 37 to determine the initial orientation of the columnar part. This drives and adjusts the adjustment component 37, so that the orientation of the two material extrusion components 33 is opposite. In other words, after the supply and discharge of the columnar part is completed once, the orientation of the columnar part when it is positioned on the two material extrusion components 33 is reversed. This makes it easier to process both ends of the columnar part by directly swapping the positions of the two material extrusion components 33, thereby improving the efficiency of material supply and discharge.

[0020] In a preferred embodiment, an extension plate 321 is fixed to one side of the inclined frame 32 corresponding to the sliding chamber, a material extrusion cylinder 322 is fixed to the upper end surface of the extension plate 321, and two position limiting plates 323 are fixed to the upper end surfaces of both of the inclined frames 32, with a stopper bar fixed inside the position limiting plate 323 located at the lower end of the inclined frame 32.

[0021] Here, as the material sorting block 34 slides downward, the sliding plate 36 becomes lower than the columnar part in the material extrusion component 33. Then the columnar part falls onto the sliding plate 36, and at this time the spring is pressed and compressed, causing the material sorting block 34 to slide upward via the telescopic cylinder 35, completing the material sorting operation of the columnar part.

[0022] If the columnar component is located within the material extrusion component 33 corresponding to the sliding chamber, the columnar component can be pre-positioned via the material extrusion cylinder 322.

[0023] As a preferred embodiment, the material extrusion component 33 is A bottom plate 331 is slidably provided within the two position limiting plates 323, and position limiting bars 332 are symmetrically fixed on both sides, with the position limiting bars 332 contacting the stopper bar to limit their position, Material extrusion side plates 333 and side plates 334 are symmetrically fixed to the upper end surface of the bottom plate 331, A storage plate 335 is fixed between the material extrusion side plate 333 and the side plate 334, and is located on the relatively higher side closer to the inclined frame 32, with a sliding bar 3351 fixed at an intermediate position. The baffle 336 is detachably attached between the material extrusion side plate 333 and the side plate 334, and is located on the side away from the storage plate 335, with a sliding groove 3361 having the same shape as the sliding bar 3351 opening at an intermediate position.

[0024] In other words, when the material extrusion component 33 corresponds to the material receiving chamber 4, the baffle 336 is positioned between the material extrusion side plate 333 and the side plate 334, blocking the columnar component, and when the material extrusion component 33 corresponds to the sliding chamber, the baffle 336 is placed on the storage plate 335, facilitating material sorting of the columnar component.

[0025] In a preferred embodiment, a reset ring 3331 is symmetrically fixed to the material extrusion side plate 333, a reset column 3333 is slidably provided within the reset ring 3331, the reset column 3333 penetrates the material extrusion side plate 333 and an extrusion plate 3332 is fixed to it, a reset spring is provided between the reset column 3333 and the material extrusion side plate 333, a drive column 3334 is fixed to the middle portion of the extrusion plate 3332 at a position corresponding to the material extrusion cylinder 322, and a handle is commonly fixed to the upper end surfaces of the material extrusion side plate 333 and the side plate 334.

[0026] In a preferred embodiment, the adjustment component 37 is: A connecting plate 371 has an adjustment motor fixed to its bottom, an adjustment column 3711 fixed to the output terminal of the adjustment motor, a positioning groove 3712 is made in the adjustment column 3711, and a reset groove 3713 is made at a position corresponding to the positioning groove 3712, A positioning cylinder 372 is fixed to the upper end surface of the connecting plate 371, An adjustment plate 373 is slidably mounted in the reset groove 3713 using a positioning column 3731, It consists of two parts, a positioning plate 374 which is symmetrically fixed to the upper end surface of the adjustment plate 373, A mounting block 375 is composed of two parts, which are symmetrically fixed to the upper end surface of the adjustment plate 373 and are located between the two positioning plates 374, A biasing cylinder 376 is fixed to the upper end surface of the connecting plate 371, A biasing block 377 is slidably mounted on the upper end surface of the connecting plate 371 by a guide column and fixed to the output end of the biasing cylinder 376, A connecting cylinder 378 is fixed to the side wall of the biasing block 377, away from the biasing cylinder 376, The system includes a connecting block 379 fixed to the output end of the connecting cylinder 378.

[0027] Here, when machining columnar parts with different ends, the direction in which the columnar part is facing on the mounting block 375 can be detected by a visual sensor. If the direction is incorrect, the biasing cylinder 376 pulls the biasing block 377, which drives the adjustment plate 373 to the connecting block 379 and slides it to the adjustment column 3711. Then, the connecting cylinder 378 detaches the connecting block 379 from the adjustment plate 373. After that, the adjustment motor rotates the adjustment plate 373 to make the adjustment. Once the adjustment is complete, the biasing cylinder 376 and connecting cylinder 378 reset the adjustment plate 373, and then the adjustment motor resets the adjustment column 3711, completing the orientation adjustment of the columnar part. As a result, it enters the numerically controlled machine tool in the same direction, improving the level of intelligence. Furthermore, the initial position of the connecting block 379 is within the connecting groove 3732, which restricts the position of the adjustment plate 373.

[0028] In a preferred embodiment, connecting grooves 3732 are symmetrically provided on both sides of the adjustment plate 373, the shape of the connecting grooves 3732 is consistent with that of the connecting block 379, and a clearance hole 3741 is provided at the center of the positioning plate 374, corresponding to the output shaft of the positioning cylinder 372.

[0029] Specifically, the material supply component 5 can simultaneously supply material to two numerically controlled machine tools 1, and the material sorting component 3 can individually supply columnar parts of different sizes, thereby facilitating gripping of the material supply component 5. Furthermore, when both ends of a columnar part need to be machined, the material is supplied via the material supply component 5 to machine one end first, and after machining is complete, it is fed into the material extrusion component 33 via the material receiving chamber 4. After machining is complete on one end of all the columnar parts, the material extrusion component 33 on the material receiving chamber 4 side and the material extrusion component 33 on the sliding chamber side are swapped to machine the other end of the columnar part, improving the efficiency of material supply. When machining columnar parts with different ends, the adjustment component 37 can adjust the direction of the columnar parts, thereby allowing the columnar parts to enter the numerically controlled machine tool 1 in the same direction and improving the level of intelligence.
