Detailed ways

In order to describe the structure, features and effects of the present utility model in detail, the following preferred embodiments are given below together with the accompanying drawings. the

As shown in Figures 1 to 5, a bar feeder (Bar feeder) 10 provided by a preferred embodiment of the present invention is matched with CNC lathes (CNC lathes) to provide automatic feeding of the length of the bar. For lathe turning, it has the same assembly components as the general commercially available similar products such as housing A, controller B, material rack C, power unit D (such as: motor, servo machine), transmission mechanism E, etc., because it is a conventional skills, so I will not repeat them. As for the operating components related to the present utility model, they are described as follows. It includes a machine platform 20 , a rod lifting device 30 , and a rod driving device 50 . the

The machine table 20 is a base composed of several metal plates, the inside of which is used to install the bar lifting device 30, and the top of the machine table 20 is used for installing the bar driving device 50. the

The rod lifting device 30 includes: a pair of turntables 31 linked by a belt 38, the two turntables 31 are arranged horizontally, and can be synchronously driven by the belt 38 to make a clockwise or counterclockwise turning movement. A load rack 33 can be lifted up by the clockwise rotation of the second turntable 31 to receive the bar G (as shown in Figure 7 ) placed on the rack C to be processed, and when the second turntable 31 rotates counterclockwise When the direction rotates, it will drive the carrying material frame 33 to descend. It must be explained here that the running direction of the turntable 31 described in this embodiment and the rising or falling of the carrying material frame 33 can have other combinations, which are not due to the disclosure of this embodiment. And be limited. The load rack 33 includes a horizontal long shaft 331, and several support columns 332 are arranged on the long shaft 331 with their bottom ends and are spaced apart from each other in the axial direction. The tops of the support columns 332 are arranged in a V shape. Rollers are used to support rods with different diameters within a specific range. In one fell swoop, the stretching frame 35 is kept movable and pivotally connected with the load frame 33, and can move up or down synchronously with the load frame 33. It includes a horizontal long shaft rod 351, and several plates 352 are respectively installed on the bottom end. The long shafts 351 are spaced apart from each other at a suitable distance, and the tops of the plates 352 are arranged as V-shaped openings for receiving rods with different diameters within a specific range. It must be noted here that the lifting frame 35 Each plate 352 is designed in a staggered manner with the adjacent corresponding supporting pillars 332 of the carrying rack 33 , so that overlapping and collision will not occur during use. A guide block 37, which is connected with the lifting frame 35 to provide the lifting frame 35 laterally moving inwardly and outwardly, which includes a first upright guide rail 371 and a second upright rail 371 adjacent to each other. Guide rail 372, the first upright guide rail 371 has the flat area 3711 of the lower half and the concave area 3712 of an upper half, during operation, make lifting and stretching material rack 35 upwards to accept the rod G to be processed by the flat area 3711, and then Through the concave area 3712, the bar to be processed on the stretching material rack 35 is shifted inward and straddled above the V-shaped roller of the support column 332 of the bearing material rack 33, and the second upright guide rail 372 has an upper half The inner concave area 3721 and the flattening area 3722 of the lower half, through the inner concave area 3721, the lifting rack 35 slides down and the bar to be processed is placed in the V-shaped roller of the support column 332 and continues to slide straight down , and then return to the outside through the leveling area 3722. It must be noted that the flat area 3711 of the lower half of the first upright guide rail 371 of the present utility model is connected with the concave area 3712 of the upper half through a slope 3713 that descends slowly. In addition, the upper half of the second upright guide rail 372 The inner concave area 3721 is also connected with the flat area 3722 of the lower half by a gently descending slope 3723 to make the lateral running of the lifting and stretching material rack 35 smooth. the

In addition, it is further emphasized that when the rod lifting device 30 is descending, the first upright guide rail 371 of the guide block 37 will be pushed to slide by a thrust at this point in time, so that the second upright guide rail 372 occupies (or is called Overlapping) at the original position of the first upright guide rail 371, conversely, when the bar lifting device 30 descends to the bottommost position, the first upright guide rail 371 will also be pulled and slipped by a pulling force at this point in time, so that The first upright guide rail 371 returns to its original position. In other words, the first upright guide rail 371 and the second upright guide rail 372 will reciprocate and alternately shift when the bar lifting device 30 operates. the

The bar driving device 50 is used to push forward the bar to be processed on the loading rack 33 to be input in the direction of the lathe shaft hole, and then return to the original position after completion. the

Through the description of the above structure, the utility model is roughly divided into three steps when used (please refer to Figures 6 to 17 at the same time). The direction of rotation is synchronous with the loading frame 33 to lift upwards and collect the bar G to be processed, and at the same time, the lifting and stretching material frame 35 is moved to the loading frame 33 through the inner concave area 3712 of the upper half of the connected first vertical guide rail 371. Approach, and then place the rod G coaxially on the V-shaped roller of the support column 332 of the load rack 33, at this time, the first vertical guide rail 371 and the second vertical guide rail 372 are driven by the external force provided by the controller to complete the position synchronously Alternate (as shown in Figures 6 to 13); then the second step is that the bar driving device 50 pushes forward the bar to be processed on the loading rack 33 to the direction of the lathe shaft hole, and returns to the original position immediately after completion (not shown in the figure); the last third step is that the two turntables 31 rotate counterclockwise, and the concave area 3721 of the second upright guide rail 372 provides the lifting frame 35 to slide down until the lifting frame 35 borrows Return outward from the leveling area 3722, and at the same time, the first vertical guide rail 371 is pulled and slipped by a pulling force, so that the first vertical guide rail 371 returns to its original position (as shown in Figures 14 to 17), so as to achieve a bar Complete feeding job. the

It can be seen from the above description that the related combined components of the utility model are exquisite in structure, and the operation process is smooth and efficient. the

The constituent components disclosed in the foregoing embodiments of the utility model are only for illustration and cannot be used to limit the scope of protection of the patent of the utility model. The substitution or change of other equivalent components should also be limited by the scope of protection of the patent of this case. cover. the
