Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled lathes, in particular to an adjustable feeding device for numerically controlled lathes. Background Art

[0002] CNC machine tool is the abbreviation of digital control machine tool, which is an automated machine tool equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the CNC device through information carriers. After calculation and processing, the CNC device sends various control signals to control the movement of the machine tool and automatically process parts according to the shape and size required by the drawing;

[0003] In the prior art, for example, a front-loading device for a CNC lathe disclosed in publication number CN220480255U records: when loading is required, the electric push rod is started to drive the first connecting plate and the second connecting plate to approach the two hydraulic limit rods until the material rod in the groove is between the two hydraulic limit rods. At this time, the hydraulic limit rod is started to press against the two ends of the material rod, and then the electric push rod is used to drive the first connecting plate and the second connecting plate away from the hydraulic limit rod. At this time, the material rod will move out at an angle of 45° from the hypotenuse of the groove (i.e., direction A). At the same time, as the material rod at the bottom layer falls out, the other material rods on the storage channel will fall down to facilitate the next loading. Only the stroke of the electric push rod needs to be set, making the entire loading and unloading simple, convenient and easy to maintain.

[0004] In actual use, the above-mentioned device is composed of fixed plates, so it can only operate materials with fixed length and diameter. In actual processing, the diameter and length of the material may change, and the above-mentioned device does not have an adjustment function and cannot cope with changes in material size. In addition, since the power part of the above-mentioned device is composed of a telescopic rod inclined at 45°, when too much and too heavy materials are placed in the material stacking area, and the telescopic rod is extended at this time, the change in the force arm will cause the entire device to tip over, which may cause machine damage and other dangerous hazards. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] Example 1

[0027] Reference Figure 1-4 , which is the first embodiment of the utility model, provides an adjustable feeding device for a CNC lathe, comprising a CNC machine tool base 1;

[0028] It also includes a feeding structure arranged outside the CNC machine tool base 1;

[0029] The feeding structure includes a main board 21 arranged on the upper side of the CNC machine tool base 1. The main board 21 can move freely on the inner side of the CNC machine tool base 1 through the cylinder telescopic rod 35 connected to the rear side, a sliding rod 22 fixedly connected to the back of the main board 21, and a side plate 23 movably connected to the main board 21. The side plate 23 is a rectangular plate, and the side plate 23 is slidably connected to the main board 21 through a sliding block. Threaded holes are provided on the side plate 23, and an inclined plate with a slope is fixedly connected on the inner side to facilitate the rolling of the upper side rod material downward while facilitating the extrusion of the lowermost side rod material. A screw rod 24 is arranged in the side plate 23, and the screw rod 24 is installed in the two side plates 23 through the threaded holes of the side plate 23. An adjusting rod 25 is fixed in the screw rod 24, and the adjusting rod 25 can be used to rotate the screw rod 24 to control the spacing between the side plates 23 on both sides.

[0030] One side of the side panel 23 is movably connected to the front panel 26, which is slidably connected to the side panel 23 via a slider, one side of the front panel 26 is fixedly connected to an L-shaped panel 27, the shorter side of the L-shaped panel 27 is fixedly connected to the side panel 23 via a spring 28, and one side of the L-shaped panel 27 is fixedly connected to the spring 28.

[0031] A bottom plate 29 is fixedly connected to the lower side of the side plate 23 , and a round hole 210 is formed in the bottom plate 29 .

[0032] The outer side of the bottom plate 29 is movably connected with a support plate 211 , and a hole with the same diameter as the circular hole 210 is opened on the support plate 211 . A latch 212 is inserted into one side of the support plate 211 , and the latch 212 needs to pass through the support plate 211 and the circular hole 210 at the same time.

[0033] The inner side of the support plate 211 is rotatably connected with a shielding buckle 213 , which is mounted on an axis inside the support plate 211 , a torsion spring 214 is mounted on the inner side of the shielding buckle 213 , and a conveying structure is disposed on the outer side of the slide rod 22 .

[0034] During use, the rods are first placed from the top of the loading structure, that is, between the inclined plates on the inner side of the front plate 26 and the side plate 23, so that the rods fall freely and are stacked at an inclined angle. The rods on the bottom side will be blocked by the shielding buckle 213 to avoid being directly squeezed out of the loading structure due to gravity. The torsion spring 214 of the shielding buckle 213 can be set to a maximum load greater than the maximum size and maximum weight of the fully loaded rods. Then the conveying structure can be used to transport the loading structure to the specified position of the CNC machine tool base 1, and the clamping device in the CNC machine tool base 1 will clamp the two ends of the rods. Because the support plate 211 is thinner than the side plate 23, the two ends of the rods on the support plate 211 will be exposed. When the clamping device is clamped, the conveying structure is retracted to bring the loading structure back to its original position. The clamped rods will squeeze the shielding buckle 213 to cause twisting. The spring 214 is twisted to open the shielding buckle 213 until the bar completely leaves the loading structure. At this time, the shielding buckle 213 loses contact with the bar, causing the torsion spring 214 to drive the shielding buckle 213 to rebound, thereby blocking the subsequent falling bar; when the length of the bar changes, it is only necessary to rotate the adjusting rod 25 to rotate the screw rod 24, and drive the side plate 23 to move to adjust the length spacing. When the diameter of the bar changes, it is necessary to remove the pin 212, change the position of the support plate 211, and then insert the pin 212 to fix it, and change the outlet size. Because the spring 28 is in a normal state when dealing with the bar with the smallest diameter during the process, when the diameter becomes larger, the spring 28 will be in a stretched state, so it will give the front plate 26 a force toward the side plate 23, thereby squeezing the inner bar while changing the spacing according to the diameter of the bar.

[0035] Example 2

[0036] Reference Figure 1-4 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: the conveying structure includes a support plate 31 arranged on the outside of the slide rod 22, the support plate 31 is slidably connected to the slide rod 22 through a slide groove 32, the slide groove 32 is opened on the support plate 31, a connecting rod 33 fixed on the side of the support plate 31, the connecting rod 33 is used to connect the CNC machine tool base 1 and the support plate 31, a support leg 34 fixed under the connecting rod 33, and a cylinder telescopic rod 35 fixed on the support plate 31.

[0037] During use, when loading is required, the cylinder telescopic rod 35 needs to be extended. When the bar at the bottom of the loading structure is completely clamped, the cylinder telescopic rod 35 can be retracted, so that the completely clamped bar can be separated from the loading structure, and the loading is completed. After that, the bar can continue to be added to the loading structure, or the bar can be filled in at intervals of several times. After the previous bar is processed, the loading can be continued according to the above steps.

[0038] The remaining structures are the same as those of Example 1.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
