After moving into position, the drilling clamping device clamps the rod to facilitate drilling. After the entire drilling process is completed, the drill assembly is reset and the rod is still in its original position, which makes it convenient for the drilling discharge device to deliver the drilled rod. In this way, the entire production line can realize automatic loading, lateral transfer and automatic drilling of the rods, with a higher degree of automation. At the same time, since the rods are fed horizontally, this further saves space.

The discharging end of the sawing and discharging conveying device is provided with an end positioning plate to effectively position the end of the bar, so that it is convenient to ensure that the end position error of the bar is small during drilling, and it is convenient for the detection sleeve to be accurately mounted on the bar to ensure the reliability of the drilling action. At the same time, the leading sizing block can facilitate the front end sizing of the bar during the transportation process before sawing, so as to ensure fixed-length cutting. At the same time, the sliding direction of the sizing slider forms an angle with the transportation direction of the bar. The impact force of the bar hitting the sizing block during the transportation process will generate component forces in two directions, thereby avoiding the sliding cooperation between the sizing slider and the sizing base more reliably.

[0042] like Figures 1 to 13 As shown, a short material sawing and drilling integrated production line includes

[0043] Upstream material turning and conveying device 6, such as Figures 2 to 5 As shown, the upstream material turning and conveying device 6 comprises an upstream material turning frame 601, on which an inclined upstream material storage platform for storing rods is arranged, and an upstream longitudinal conveying device 603 is arranged on the lower side of the upstream material storage platform, and an upstream material turning mechanism 604 for conveying the rods on the upstream material storage platform to the upstream longitudinal conveying device 603 one by one is arranged on the upstream material turning frame 601;

[0044] The upstream material storage platform includes a plurality of support beams 602 for placing rods, which are arranged on the upstream turning machine frame 601. The upper end of the support beam 602 is provided with an inclined guide support surface for facilitating the rolling of the rods. In this embodiment, the support beam 602 includes a beam body 6021 and a guide support plate 6022. The guide support plate 6022 can be detachably fixed on the beam body 6021. The guide support surface is arranged on the guide support plate 6022. The guide support surface has a T-shaped cross section. By replacing the guide support plate 6022, the guide support surface with different inclinations can be adjusted to meet the guiding requirements of rods of different sizes.

[0045] The lower side of the guide support surface of the support beam 602 is the lateral discharge side, and the lateral discharge side of the upstream material turning frame 601 is provided with an upstream longitudinal conveying device 603, and the upstream longitudinal conveying device 603 includes a conveying roller 6031 rotatably mounted on each support beam 602, and the roller shafts of each conveying roller 6031 are connected by step-by-step transmission, and the roller shaft of one conveying roller 6031 is connected by transmission to the output shaft of the reduction motor 6032 fixed on the upstream material turning frame 601. The step-by-step transmission connection method adopts a transmission chain 6033 transmission, and two sprockets are fixed on the roller shaft of each conveying roller 6031, which facilitates the step-by-step transmission between the roller shafts of the conveying rollers 6031.

[0046] A limited blocking mechanism 605 is installed on at least two supporting beams 602 for transverse sliding. The upstream turning frame 601 is provided with a transverse adjustment mechanism 606 for adjusting the transverse position of the limited blocking mechanism 605. The limited blocking mechanism 605 is provided with an internal blocking structure for blocking the rods on the supporting beam 602 and an external positioning structure for positioning the rods to fall onto the longitudinal conveying device.

[0047] The upstream material turning mechanism 604 includes at least two material turning push plates 6041, which are rotatably installed on different supporting beams 602. The material turning push plates 6041 are located below the guide support surface when in the avoidance position.

The material turning push plates 6041 are higher than the guide support surface when in the turning position. The material turning power device 6042 includes the same number of material turning cylinders as the material turning push plates 6041. One end of the material turning cylinder is hinged to the upstream material turning frame 601, and the other end is hinged to the corresponding material turning push plates 6041. Figure 3 As shown, Figure 3 Only one installation structure of the material turning push plate 6041 is drawn, which can be longitudinally distributed on the upstream material turning frame 601 according to the actual length of the rod. The above structure is adopted, and the cost is relatively low. Multiple cylinders can be used to drive the turning of the material turning push plate 6041 to ensure that the turning force is sufficient. Of course, the material turning power device 6042 can also include a material turning cylinder, one end of which is hinged on the upstream material turning frame 601, and the other end is respectively hinged on one of the material turning push plates 6041, and the rotation center axis 6043 of each material turning push plate 6041 is the same rotation center axis 6043 or a synchronous shaft is connected between the rotation center axes 6043. In this way, when the material turning cylinder drives a material turning push plate 6041 to turn over, the material turning push plate 6041 will drive the rotation center axis 6043 to rotate, and then drive all the material turning push plates 6041 to turn over through the synchronous shaft, which can also achieve the unification of the material turning action.

[0048] The position-limiting and blocking mechanism 605 includes a plurality of position-limiting and blocking blocks 6051 which are laterally slidably mounted on the supporting crossbeam 602.

The limit stop block 6051 is transversely slidably mounted on the supporting beam 602 in the following manner: a transverse bar hole 6055 is arranged on the limit stop block 6051, and the limit stop block 6051 is fixed to the side plate of the supporting beam 602 through a pressing plate 6056 and a locking bolt, and the locking bolt is constrained in the transverse bar hole 6055. The adjusting fixing seat 6064 is also provided with a tightening screw 6065 for tightening the end of the position-limiting stopper 6051. The tightening screw 6065 can not only facilitate the position adjustment of the position-limiting stopper 6051, but also tighten the position-limiting stopper 6051 after the position adjustment to prevent it from loosening.

[0050] In addition, a pointer 6057 is installed on the limit blocking block 6051, and a scale 6058 is provided on the corresponding supporting beam 602 to facilitate the indication of the pointer 6057, thereby making the position adjustment more reliable.
