[0019] The technical solutions of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0020] In the description of the present application, it should be noted that the orientations or positional relationships indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", "third" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance.

[0021] As Figures 1 to 5The utility model discloses a kind of milling equipment for bar processing, including machine table 1, material bin 2 is equipped on machine table 1, material bin 2 top is equipped with the downward recessed material groove 21 formed, material groove 21 is used to stack bar, one side wall of material bin 2 is equipped with the rectangular material mouth 22 being communicated with material groove 21, material groove 21 is symmetrically equipped with the inclined material guiding arm 3, material guiding arm 3 extends along the direction towards material mouth 22, its height decreases in turn, so that the bar contacted with material guiding arm 3 can be rolled to material mouth 22 under the action of gravity.

[0022] Material bin 2 outside is equipped with feeding rod 4, and the two ends of the feeding rod 4 are rotatably connected to the connecting flanges 9 symmetrically arranged on the outer wall of the material bin 2 through bearings. Two strip baffles 10 are fixedly sleeved on the outer periphery of the feeding rod 4. The strip baffles 10 correspond in position to the material guiding arms 3. When the bar is rolled to the material mouth 22, the strip baffles 10 can block the bar (at this time, the strip baffles 10 are approximately perpendicular to the material guiding arms 3), so that the bar can be kept in the material groove 21. Symmetrical material pushing arms 11 are arranged between the two strip baffles 10 and are fixedly sleeved on the outer periphery of the feeding rod 4. When the strip baffles 10 block the bar, one end of the material pushing arm 11 extends towards the material guiding arm 3 and is approximately parallel to the material guiding arm 3. At this time, after the feeding rod 4 is rotated, the strip baffles 10 can rotate with the feeding rod 4, changing from being approximately perpendicular to the material guiding arms 3 to being approximately parallel. The material pushing arm 11 rotating with the feeding rod 4 can lift the bar previously blocked by the strip baffles 10 while blocking the subsequent bar. In this way, the bar in the material groove 21 can be guided one by one to the receiving frame 14 described below, so that only by rotating the feeding rod 4, multiple bars can be fed one by one, improving the convenience of feeding.

[0023] In the embodiment, the feeding rod 4 is mainly rotated by the driving device. The driving device includes a base 122 fixed on the machine table 1, a base of a driving cylinder 121 mounted on the base 122 through a pin shaft, a driving block 123 fixed on the end of the piston rod of the driving cylinder 121, and a connecting rod 124 hingedly connected to the driving block 123 through a pin shaft. One side end of the feeding rod 4 extends to form a connecting end, and the connecting end is connected to the driving device through the connecting rod 124. When the driving cylinder 121 is extended and retracted, the feeding rod 4 is reciprocatingly rotated around the axis, so that the material pushing arm 11 pushes the bars one by one to the receiving frame 14.

[0024] The machine table 1 is fixed with the receiving frame 14, and the receiving frame 14 is provided with a shaped holding groove for positioning the bar. The machine table 1 is provided with a first sliding table 5 that can slide. The first sliding table 5 is driven in a linear motor or screw rod manner. This is prior art, and therefore will not be described in detail. The first sliding table 5 is fixed with a transmission box 6, and the transmission box 6 is provided with a cutter shaft 7 driven by a motor. The left end of the cutter shaft 7 is provided with a milling cutter head 8. When the bar is pushed to the holding groove, the first sliding table 5 drives the cutter shaft 7 to feed along the axial direction of the bar, and at the same time, the cutter shaft 7 rotates at a high speed to complete the milling process.

[0025] In the embodiment, the clamping device coaxial with the receiving frame 14 is arranged on the machine table 1. The clamping device comprises a second sliding table 131 slidable on the machine table 1, and the structure of the second sliding table 131 is the same as that of the first sliding table 5. A machine frame 132 is fixed on the second sliding table 131, the front end of the machine frame 132 is connected with a rotating shaft 133 through a bearing, one end of the rotating shaft 133 is fixed with an ejecting cylinder 134, the output end of the ejecting cylinder 134 is connected with an ejecting block 139, and a mounting seat 135 is fixed on the top of the ejecting cylinder 134 through bolts, the center of the mounting seat 135 is provided with a through hole 135a for the output end of the ejecting cylinder 134 to extend out, four guide grooves 135b are radially arranged on the outer periphery of the through hole 135a, and a clamping block 136 is embedded in each guide groove 135b. A first inclined side wall 136a is arranged on the inner side of the clamping block 136, and a second inclined side wall 139a is arranged on the outer periphery of the ejecting block 139. A spring 138 is arranged between the clamping block 136 and the bottom plate 137 of the mounting seat 135.

[0026] When the ejecting cylinder 134 pushes the ejecting block 139 to eject, the second inclined side wall 139a is coupled with the first inclined side wall 136a, so as to force the clamping block 136 to radially extrude the spring 138 along the guide groove 135b, so that the bar can be released; when the cylinder is retracted, the spring 138 pushes the clamping block 136 to reset to clamp the bar. One end of the rotating shaft 133 is connected with a corresponding motor, so that the clamped bar can be driven to rotate through the motor, and multi-surface machining is realized in cooperation with the milling cutter head 8.

[0027] The embodiment is only an explanation of the utility model, and is not a limitation of the utility model. Those skilled in the art can make modifications to the embodiment without creative contribution after reading the specification, but as long as the modifications are within the scope of the claims of the utility model, they are protected by the patent law.
