Description

Technical Field

[0001] This utility model relates to the field of bolt processing technology, specifically to an automatic feeding CNC lathe for processing hexagonal bolts. Background Technology

[0002] A hex bolt is a fastener consisting of a head and a threaded shank. Bolts are classified by material into iron bolts and stainless steel bolts, also known as hex head bolts. They are a type of fastener consisting of a head and a threaded shank (a cylinder with external threads), requiring a nut for fastening two parts with through holes. This type of connection is called a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated; therefore, a bolted connection is a detachable connection. Hex bolts are the most widely used, standardized, and varied fasteners in the mechanical field. Hex bolts are typically mass-produced using cold forging machines. However, some formed bolts require drilling to accommodate different components and adapt to various operating environments. Drilling a hole in a bolt does not mean opening a hole in a steel plate; rather, it involves drilling a through hole axially or radially in the bolt shank or head to insert a cotter pin, fuse, or for weight reduction.

[0003] In the current technology, the drilling of bolt shanks is mostly done on a lathe, which requires a three-jaw chuck for clamping during use, resulting in slow processing efficiency. Utility Model Content

[0004] To overcome the above-mentioned defects, the present invention provides an automatic feeding CNC lathe for machining hexagonal bolts, which solves the technical problem of an automatic feeding CNC lathe for machining hexagonal bolts in related technologies / prior technologies.

[0005] According to one aspect, at least one embodiment of the present invention provides an automatic feeding CNC lathe for machining hexagonal bolts, comprising: a vertical machine tool, the vertical machine tool including a drilling frame and a transmission mechanism, wherein drilling mounting blocks are arranged in an array inside the transmission mechanism, a circular mounting block is mounted on the upper surface of the drilling mounting block, the upper surface of the circular mounting block is provided with an internal hexagonal slot, a lifting guide rail is provided on one side of the transmission mechanism, a drilling pressure plate is mounted inside the lifting guide rail above the drilling mounting block, a drilling support block is mounted below the drilling mounting block corresponding to the position of the drilling pressure plate, an upper limit cover groove is provided on the lower surface of the drilling pressure plate corresponding to the position of the circular mounting block, and a drill bit through hole is provided inside the upper limit cover groove through the drilling pressure plate.

[0006] For example, in an automatic feeding CNC lathe for processing hexagonal bolts provided in at least one embodiment of this utility model, a lifting screw is installed between the inside of the lifting guide rail and the drilling pressure plate, and a lifting motor is installed at the upper end of the lifting screw on the upper surface of the lifting guide rail.

[0007] For example, in an automatic feeding CNC lathe for processing hexagonal bolts provided in at least one embodiment of the present invention, a support base is installed at the lower end of the transmission mechanism, a bolt material storage bin is installed on the upper surface of the support base located on one side of the transmission mechanism, and a drive motor is installed on one side of the upper end of the drilling frame.

[0008] For example, in an automatic feeding CNC lathe for processing hexagonal bolts provided in at least one embodiment of this utility model, a movable rotating shaft is connected between two adjacent drilling mounting blocks, the circular mounting block is fixedly connected to the drilling mounting block, and a stud through hole penetrating the drilling mounting block is opened inside the internal hexagonal slot.

[0009] For example, in an automatic feeding CNC lathe for processing hexagonal bolts provided in at least one embodiment of this utility model, the inner diameter of the upper limit cover groove is the same as the outer diameter of the circular mounting block.

[0010] For example, in an automatic feeding CNC lathe for processing hexagonal bolts provided in at least one embodiment of this utility model, the drilling support block is fixedly connected to the transmission mechanism, and a de-driving mechanism is installed on one side of the transmission mechanism.

[0011] For example, in an automatic feeding CNC lathe for processing hexagonal bolts provided in at least one embodiment of this utility model, the drilling pressure plate is a Z-shaped structural component and the drilling support block is a U-shaped structural component.

[0012] For example, in an automatic feeding CNC lathe for processing hexagonal bolts provided in at least one embodiment of this utility model, a transmission belt is installed between the drive motor and the drilling frame.

[0013] For example, in an automatic feeding CNC lathe for processing hexagonal bolts provided in at least one embodiment of this utility model, the drilling pressure plate is engaged with the lifting screw, and the drilling pressure plate is slidably connected to the lifting guide rail.

[0014] For example, in an automatic feeding CNC lathe for processing hexagonal bolts provided in at least one embodiment of this utility model, a material dropping through hole is provided on the lower surface of the bolt material storage bin corresponding to the position of the circular mounting block.

[0015] The beneficial effects of this utility model are as follows: In this invention, by placing the screw rod entirely inside the circular mounting block, the threaded through hole allows the screw rod to be inserted. The hexagonal countersunk head of the bolt to be processed is limited inside the circular mounting block. Therefore, the drilling pressure plate is driven to press down, and the limiting cover groove covers the outside of the circular mounting block to limit the bolt. The drill bit through hole position is then used to drill the bolt.

[0016] The U-shaped drilling support block supports both ends of the drilling mounting block, while the hollow structure in the middle prevents material from being pushed out after the bolt is inserted into the circular mounting block. At the same time, when drilling is being performed, the drilling support block can provide support to prevent the transmission belt from breaking due to excessive pressure when the pressure is applied to the screw position inside the drilling mounting block.

[0017] Multiple drilled mounting blocks arranged in an array inside the transmission mechanism are connected by a rotating shaft to form a transmission belt. In conjunction with the upper feeding of the bolt material storage bin at the end, when the multiple drilled mounting blocks at the upper position move as a whole to a vertically downward position, the bolts with completed holes placed inside the circular mounting blocks will fall directly under the action of gravity, thus achieving the purpose of automatic feeding.

[0025] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] like Figures 1-5 As shown, this invention illustrates an automatic feeding CNC lathe for machining hexagonal bolts according to one embodiment. Multiple drilling mounting blocks 401 arranged in an array inside a transmission mechanism 4 are connected by rotating shafts to form a transmission belt. Toothed blocks are provided on the lower surface of each drilling mounting block 401. A drive mechanism is installed on one side of the transmission mechanism 4. A gear installed at the end of the drive mechanism meshes with the toothed blocks on the lower surface of the drilling mounting blocks 401 to rotate them, thereby controlling the rotation of the multiple drilling mounting blocks 401 to feed the machined bolts. A circular mounting block 402 is mounted on the upper surface of each drilling mounting block 401, and is fixedly connected to it. The circular mounting block 402 is used to install bolts. An internal hexagonal slot 403 is provided on the upper surface of the circular mounting block 402. The slot 403 has a through hole for the stud to penetrate the drilling mounting block 401. The hexagonal screw to be processed is then placed into the drilling mounting block 401, with the lower end inserted through the stud hole. The upper hexagonal countersunk head of the screw is engaged with the internal hexagonal slot 403 for positioning. A drilling support block 404 is installed below the drilling mounting block 401, corresponding to the drilling pressure plate 501. The drilling support block 404 is a U-shaped structure and is fixedly connected to the transmission mechanism 4. The drilling support block 404 is positioned directly below the drilling mounting block 401. During drilling, when pressure is applied to the screw inside the drilling mounting block 401, the drilling support block 404 provides support to prevent the transmission belt from breaking due to excessive pressure.

[0027] In some examples, the U-shaped drilling support block 404 supports the two ends of the drilling mounting block 401, while the hollow structure in the middle can prevent material from being pushed out after the bolt is inserted into the circular mounting block 402. After drilling is completed, the drilling mounting block 401 is rotated to move the bolt material in the subsequent position forward. When the multiple drilling mounting blocks 401 in the upper position move to a vertically downward position, the bolt with the completed hole placed in the circular mounting block 402 will fall directly under the action of gravity, which can achieve the purpose of automatic material feeding.

[0028] In some examples, such as Figure 3 , 4 As shown, a lifting guide rail 5 is provided on one side of the transmission mechanism 4. A drilling pressure plate 501 is installed inside the lifting guide rail 5 above the drilling mounting block 401. The drilling pressure plate 501 is a Z-shaped structure component. An upper limit cover groove 505 is opened on the lower surface of the drilling pressure plate 501 corresponding to the position of the circular mounting block 402. The inner diameter of the upper limit cover groove 505 is the same as the outer diameter of the circular mounting block 402. When the screw is completely stuck inside the internal hexagonal slot 403, the drilling pressure plate 501 is driven to cover the circular mounting block 402. The upper limit cover groove 505 on the lower surface of the drilling pressure plate 501 completely covers the outside of the circular mounting block 402 to limit the screw. A drill bit through hole 502 is opened through the drilling pressure plate 501 inside the upper limit cover groove 505 so that drilling can be performed.

[0029] refer to Figure 2 and Figure 4 In some embodiments, a lifting screw 503 is installed inside the lifting guide rail 5 and between it and the drilling pressure plate 501. The drilling pressure plate 501 is engaged with the lifting screw 503 and slidably connected to the lifting guide rail 5. A lifting motor 504 is installed at the upper end of the lifting screw 503 on the upper surface of the lifting guide rail 5. A support base 6 is installed at the lower end of the transmission mechanism 4. A bolt material storage bin 7 is installed on the upper surface of the support base 6 on one side of the transmission mechanism 4. A material drop hole is opened on the lower surface of the bolt material storage bin 7 corresponding to the position of the circular mounting block 402. A drive motor 3 is installed on one side of the upper end of the processing frame 2. A transmission belt is installed between the drive motor 3 and the drilling processing frame 2. The drilling pressure plate 501 is raised and lowered on the lifting guide rail 5. When the drilling processing frame 2 is pressed down to open the bolt hole, the drilling pressure plate 501 is pressed down to cover the bolt on the outside of the circular mounting block 402 to prevent it from moving. When the drilling is completed, the drilling processing frame 2 is raised as a whole. At the same time, the lifting motor 504 drives the drilling pressure plate 501 to rise as a whole, which drives the subsequent drilling mounting block 401 to move to the position directly below the drilling processing frame 2.

[0030] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
