Description

Technical Field

[0001] The utility model relates to the technical field of fine screw processing, in particular to a feeding device for the fine screw. Background Art

[0002] At present, the fine screw is a cylinder with a spiral groove cut on the outer surface or a cone with a conical spiral groove cut on the conical surface. The fine screw has different heads. The head is called an external hexagonal screw, and there are others, such as a large flat screw, an internal hexagonal screw, etc. When processing the fine screw, it is necessary to cut a very long metal rod into a fixed length of rod to be processed, and then process the fine screw thread.

[0003] When cutting metal rods into fixed lengths of rods to be processed, it is often necessary to manually clamp the screw rods and then use a cutting machine to cut the screw rods, which is time-consuming and labor-intensive. However, there is a lack of effective limiting guide structure during the cutting process, which makes it lack stability during cutting and affects product quality. Utility Model Content

[0004] In order to solve the technical problems that the screw needs to be clamped manually and then cut by a cutting machine, which is time-consuming and labor-intensive, lacks stability during cutting, and affects product quality, the utility model provides a feeding device for a thin screw.

[0005] The utility model is implemented by the following technical scheme: a feeding device for a fine screw, comprising a base, a leg fixedly mounted on the lower surface of the base, a conveying mechanism arranged inside the base for stably conveying the processing material of the fine screw, and a cutting mechanism matched with the conveying mechanism is arranged at one end of the base for cutting the processing material of the fine screw to a fixed length, a cutting table fixedly mounted on the lower surface of the base is arranged below the cutting mechanism, and a cutting groove corresponding to the cutting mechanism is opened in the middle of the cutting table.

[0006] As a further improvement of the above scheme, the cutting mechanism includes a bracket fixedly connected to the upper surface of the base, a sliding groove is provided on the opposite surface of the bracket, a cross plate is slidably connected inside the sliding groove, and a spring is provided at the bottom of the sliding groove, and the top of the spring is connected to the cross plate.

[0007] As a further improvement of the above solution, the top of the base is rotatably connected to a transmission shaft, and the middle of the transmission shaft is fixedly connected to an eccentric disk corresponding to the cross plate.

[0008] As a further improvement of the above solution, a fixing plate is fixedly connected to the lower surface of the transverse plate, and a cutting knife corresponding to the cutting groove is fixedly installed on the bottom of the fixing plate.

[0009] Through the above technical solution, the eccentric disk continuously squeezes the cross plate to drive the cutter to move up and down, thereby completing the fixed-length cutting of the thin screw rod, speeding up work efficiency and improving product quality.

[0010] As a further improvement of the above solution, the conveying mechanism includes a conveying roller rotatably installed inside the base, a conveying groove is opened on the upper surface of the base, and a motor for driving the conveying roller is arranged on one side of the base.

[0011] Through the above technical solution, the conveying roller is driven to rotate by the rotation of the motor, so that the fine screw rod moves forward in the conveying trough, which limits the rod while automatically unloading the material, thereby improving the stability during cutting.

[0012] As a further improvement of the above scheme, the motor drives the transmission shaft through a transmission assembly, and the transmission assembly includes pulleys fixedly connected to the motor output end and one end of the transmission shaft respectively, and the pulleys are driven by belts. A collection box is provided at one end of the base.

[0013] Through the above technical solution, the cut rods are continuously transported forward by the conveying rollers, so that they are pushed and fall into the collection box below, which is convenient for collection and improves work efficiency.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The utility model drives the transmission shaft to rotate through the transmission assembly while the motor rotates, thereby rotating the eccentric disk, so that the eccentric disk squeezes the cross plate to slide downward. When the eccentric disk is not in contact with the cross plate, the spring resets the cross plate, so that the cross plate drives the cutter to move up and down continuously, and then cooperates with the cutting groove to cut the delivered rod to a fixed length. The design can stably transport the rods and can also realize the fixed-length cutting of the rods, thereby speeding up the work efficiency and improving the product quality.

[0026] Please combine Figure 2 The top of the base 1 is rotatably connected to a transmission shaft 14 , and the middle of the transmission shaft 14 is fixedly connected to an eccentric disk 15 corresponding to the horizontal plate 10 .

[0027] Please combine Figure 2 A fixing plate 12 is fixedly connected to the lower surface of the horizontal plate 10 , and a cutting knife 13 corresponding to the cutting groove 7 is fixedly installed at the bottom of the fixing plate 12 .

[0028] The eccentric disk 15 continuously squeezes the transverse plate 10 to drive the cutter 13 to move up and down, thereby completing the fixed-length cutting of the thin screw rod, speeding up the work efficiency and improving the product quality.

[0029] Please combine Figure 1 The conveying mechanism includes a conveying roller 4 rotatably installed inside the base 1 , a conveying groove 2 is opened on the upper surface of the base 1 , and a motor 5 for driving the conveying roller 4 is arranged on one side of the base 1 .

[0030] The conveying roller 4 is driven to rotate by the rotation of the motor 5, so that the fine screw rod moves forward in the conveying trough 2, which limits the rod while automatically unloading the material, thereby improving the stability during cutting.

[0031] Please combine Figure 1 and Figure 4 The motor 5 drives the transmission shaft 14 through the transmission assembly 16. The transmission assembly 16 includes pulleys fixedly connected to the output end of the motor 5 and one end of the transmission shaft 14 respectively. The pulleys are driven by belts.
