Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a material bin for numerical control machine tools. Background Art

[0002] CNC machine tools are automated machine tools controlled by computer programs. When processing workpieces, CNC machine tools usually use manipulators in conjunction with silos to retrieve and discharge materials. That is, the manipulator takes the workpiece to be processed from the silo and sends it to the spindle for processing, and puts the processed workpiece back into the silo. When CNC machine tools are working, they will process workpieces of different sizes. For example, different shaft workpieces have different diameters and lengths. Therefore, the silo used to transport workpieces needs to be able to accommodate shaft workpieces of different sizes within a certain range. Otherwise, frequent replacement of the corresponding parts of the silo will reduce the efficiency of the manipulator in retrieving materials. Utility Model Content

[0020] like Figures 1 to 4As shown, in one embodiment of the utility model, the CNC machine tool silo includes a base 1, a ramp housing 2, a material plate 3, a cylinder 4, a side baffle plate 5 and a front baffle plate 6. The ramp housing 2 is arranged on the base 1, and the lower end of the ramp housing 2 is provided with an opening 21 connected to the inner cavity; the material plate 3 is horizontally arranged and slidably connected to the inner cavity of the ramp housing 2, the front end of the material plate 3 passes through the opening 21 and is provided with a U-shaped material trough 7 for accommodating shaft workpieces 40, the U-shaped material trough 7 passes through both sides of the material plate 3 horizontally, and the U-shaped material trough 7 is provided with a material taking port 8 that passes through the material plate 3 vertically; the cylinder 4 is arranged in the inner cavity of the ramp housing 2 and the output end is connected to the rear end of the material plate 3; the side baffle plates 5 are arranged on both sides of the ramp housing 2; the front baffle plate 6 is arranged in front of the opening 21, and the front baffle plate 6 is provided with a discharge port 61 through which the material plate 3 passes, and the upper edge of the discharge port 61 is flush with the top surface of the material plate 3; the side baffle plates 5 and the side baffle plates 5 form an inclined trough body at the top of the ramp housing 2.

[0021] The working principle of the CNC machine tool silo is:

[0022] When the material sheet 3 is in the material receiving state, the U-shaped material trough 7 is located on the inner side of the front baffle plate 6 and is close to the front baffle plate 6. The top surface of the material sheet 3 is flush with the upper edge of the discharge port 61. The shaft workpiece 40 to be processed is put in from the upper end of the ramp shell 2. The shaft workpiece 40 can slide down to the lower end along the top inclined surface of the ramp shell 2 due to its own gravity. At this time, due to the blocking effect of the front baffle plate 6, the shaft workpiece 40 can just fall into the U-shaped material trough 7. Since the U-shaped material trough 7 runs horizontally through both sides of the material sheet 3, shaft workpieces 40 of different diameters and lengths within a certain range can fall into the U-shaped material trough 7, and the versatility is good; when the material sheet 3 is in the material pushing state, the shaft workpiece 40 has fallen into the U-shaped material trough 7, and the output end of the cylinder 4 pushes the material sheet 3 to move forward. The front end of the material sheet 3 carries the shaft workpiece 40 out of the discharge port 61, and since the U-shaped material trough 7 is provided with a feeding port 8, it is convenient for the manipulator to take the shaft workpiece 40.

[0023] In some embodiments of the present invention, Figure 4 As shown, at least one linear guide rail 9 is provided under the material plate 3, and the linear guide rail 9 is horizontally fixed in the inner cavity of the ramp shell 2. A plurality of sliders 10 are slidably connected to the linear guide rail 9, and the sliders 10 are fixedly connected to the material plate 3. By setting the linear guide rail 9 and the sliders 10, the material plate 3 can work more smoothly.

[0024] In some embodiments of the present invention, Figures 3-4 As shown, the material plate 3 includes a push plate 31 and a receiving plate 32. The receiving plate 32 is detachably connected to the front end of the push plate 31, and the receiving plate 32 is flush with the push plate 31. The receiving plate 32 with different sizes of U-shaped material trough 7 can be replaced according to the size of the shaft workpiece 40; the output end of the cylinder 4 is fixedly connected to the push plate 31; the U-shaped material trough 7 and the material outlet 8 are arranged on the receiving plate 32.

[0025] In some embodiments of the present invention, Figure 1 As shown, an optical fiber sensor 20 is provided in front of the discharge port 61; the optical fiber sensor 20 is a counter-radiation optical fiber sensor, which is respectively located on both sides in front of the discharge port 61, and a sensor bracket 30 is provided on the optical fiber sensor 20, and the sensor bracket 30 is installed on the base 1. When the front end of the material plate 3 passes through the discharge port 61 with the shaft workpiece 40, the optical fiber sensors 20 on both sides can detect the U-shaped material trough 7. When the shaft workpiece 40 is detected, the receiver of the optical fiber sensor 20 converts the optical signal into an electrical signal and outputs the detection result to the manipulator control system, so that the manipulator can take the material from the material taking port 8. The utility model can realize automatic feeding by setting the cylinder 4, and can realize accurate feeding by setting the optical fiber sensor 20.

[0026] It should be understood that all the above embodiments are illustrative rather than restrictive, and any modifications, equivalent changes and modifications made by those skilled in the art to the specific embodiments described above under the conception of the present invention are still within the scope of the technical solution of the present invention.
