Description

Technical Field

[0001] This utility model relates to the field of screw press technology, specifically a screw press for processing carbon-carbon composite materials with full thread. Background Technology

[0002] A full-thread screw machining machine is a specialized piece of equipment used to process fully threaded screws (i.e., screws with continuous threads throughout). It is widely used in construction, machinery manufacturing, conveying equipment, automated production lines and other fields.

[0003] Carbon-carbon composite materials are high-performance composite materials with carbon fiber as reinforcement and carbon (or graphite) as matrix. They have excellent properties such as lightweight, high strength, high temperature resistance, thermal shock resistance, and low coefficient of thermal expansion.

[0004] When machining carbon-carbon composite rods, screw presses are less prone to bending for larger diameter carbon-carbon composites due to their high strength. However, when machining smaller diameter carbon-carbon composites (e.g., less than 10mm) and of a certain length, bending becomes a problem, affecting the machining results. Therefore, a screw press for machining carbon-carbon composite rods with full threading is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a screw machine for processing carbon-carbon composite materials with full thread, so as to solve the problem mentioned in the background art that when the diameter of the carbon-carbon composite material being processed is small (such as less than 10mm), and the carbon-carbon composite material being processed reaches a certain length, the carbon-carbon composite material is prone to bending, which affects the processing effect of the carbon-carbon composite material rod.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A screw machine for machining carbon-carbon composite materials with full thread includes a screw machine body, a limiting plate, a fixing plate, a clamping assembly, and a protective assembly. The clamping assembly is installed at both ends of the limiting plate, and the protective assembly is installed below the fixing plate. The protective assembly prevents the carbon-carbon composite rod from bending during use.

[0007] Preferably, the protective component includes a movable plate, an arc plate, and pulleys. The arc plate is located below the fixed plate, and the movable plate is located above the arc plate. Pulleys are embedded in the middle of both the movable plate and the arc plate.

[0008] Preferably, a symmetrical support plate is provided below the fixed plate, a movable plate is sleeved on the surface of the support plate, and a rectangular frame is slidably connected to the surface of the support plate, the rectangular frame being fixedly connected to the top of the arc plate.

[0009] Preferably, a movable frame is slidably connected to the surface of the fixed plate, a support plate is fixedly connected to the bottom of the movable frame, and screws are threadedly connected to the surfaces of the movable frame, the movable plate, and the rectangular frame.

[0010] Preferably, the clamping assembly includes a clamping block, a lead screw, a disc, and a rocker arm. The clamping block is slidably connected to the bottom position of the end of the limiting plate, and the lead screw is threadedly connected to the end face of the limiting plate. One end of the lead screw contacts the clamping block, and the other end of the lead screw is fixedly connected to the disc. A rocker arm is installed at the outer edge of the disc.

[0011] Preferably, the end of the limiting plate is provided with a rectangular groove at the top position of the clamping block, and symmetrical sliding rods are fixedly connected to the inner wall of the rectangular groove. A slider is slidably connected to the surface of the sliding rod, and the clamping block is fixedly connected to the bottom of the slider.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention features a movable frame that can slide laterally on the surface of a fixed plate. The bottom of the movable frame is connected to symmetrical support plates. One end of the support plate is movably connected to an arc plate via a rectangular frame, and the other end of the support plate is slidably connected to the movable plate. Both the movable plate and the arc plate have pulleys at their middle positions. When the screw press processes carbon-carbon composite rods, the movable plate and the arc plate are placed above and below the carbon-carbon composite rod, respectively, and both pulleys are in contact with the carbon-carbon composite rod, providing support and protection to prevent bending during the processing of the carbon-carbon composite rod.

[0013] This utility model has lead screws at both ends of the limiting plate, which drive the disk to rotate via rocker arms. A rectangular groove is opened at the end of the limiting plate to set a sliding rod to connect the slider. The bottom of the slider is connected to a clamping block. The clamping block is pushed close to the screw machine body by the lead screw, which facilitates the assembly of the limiting plate and the screw machine body. Attached Figure Description

[0016] To facilitate the solution of the problem, this utility model provides a screw press for machining full-threaded carbon-carbon composite materials. The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example

[0017] like Figures 1 to 4 As shown, this embodiment provides a screw machine for processing carbon-carbon composite materials with full thread, including a screw machine body 1, a limiting plate 2, a fixing plate 3, and also includes a clamping assembly and a protective assembly. The clamping assembly is installed at both ends of the limiting plate 2, and the protective assembly is installed below the fixing plate 3. When in use, the protective assembly prevents the carbon-carbon composite material rod from bending.

[0018] By setting a limiting plate 2 with a fixing plate 3 on the top of the screw machine body 1, and assembling it with the screw machine body 1 by the clamping components at both ends of the limiting plate 2, assembly is convenient. Then, the protective component below the fixing plate 3 is snapped onto the surface of the carbon-carbon composite rod, which provides support and protection and prevents bending during the processing of the carbon-carbon composite rod.

[0019] Reference Figure 1 , Figure 2 and Figure 4 As one embodiment of this utility model, the protective component specifically includes a movable plate 14, an arc plate 16 and a pulley 17. The arc plate 16 is provided below the fixed plate 3, and the movable plate 14 is provided above the arc plate 16. The pulley 17 is embedded in the middle of both the movable plate 14 and the arc plate 16.

[0020] By placing the movable plate 14 and the arc plate 16 above and below the carbon-carbon composite rod respectively, and ensuring that both pulleys 17 are in contact with the carbon-carbon composite rod, the rod is provided with local support and protection, greatly reducing the likelihood of bending.

[0021] Reference Figure 1 , Figure 2 and Figure 4 As one embodiment of this utility model, specifically, a symmetrical support plate 12 is provided below the fixed plate 3, a movable plate 14 is sleeved on the surface of the support plate 12, and a rectangular frame 15 is slidably connected to the surface of the support plate 12. The rectangular frame 15 is fixedly connected to the top of the arc plate 16.

[0022] A support plate 12 is installed below the fixed plate 3. On the one hand, the support plate 12 is connected to the arc plate 16 through the rectangular frame 15, which facilitates the adjustment of the position of the arc plate 16 on the surface of the support plate 12, and thus facilitates the adjustment of the height of the arc plate 16, making it easy to adapt to carbon-carbon composite rods of different sizes. On the other hand, the support plate 12 is slidably connected to the movable plate 14, which facilitates the adjustment of the position of the movable plate 14 on the surface of the support plate 12, and thus facilitates the adjustment of the height of the movable plate 14.

[0023] Reference Figure 1 , Figure 2 and Figure 4 As one embodiment of this utility model, specifically, a movable frame 11 is slidably connected to the surface of the fixed plate 3, and a support plate 12 is fixedly connected to the bottom of the movable frame 11. The surfaces of the movable frame 11, the movable plate 14, and the rectangular frame 15 are all threaded with screws 13.

[0024] By setting a sliding movable frame 11 on the surface of the fixed plate 3 to connect the support plate 12, it is convenient to adjust the position of the support plate 12 on the surface of the fixed plate 3, and to facilitate the assembly and use of the support plate 12 with the screw machine body 1. In addition, screws 13 are set on the surfaces of the movable frame 11, the movable plate 14 and the rectangular frame 15 to facilitate locking after the position of the support plate 12, the movable plate 14 and the arc plate 16 is adjusted.

[0025] Reference Figure 1 , Figure 2 and Figure 3 As one embodiment of this utility model, specifically, the clamping assembly includes a clamping block 7, a lead screw 8, a disc 9, and a rocker arm 10. The clamping block 7 is slidably connected to the bottom position of the end of the limiting plate 2, and the lead screw 8 is threadedly connected to the end face of the limiting plate 2. One end of the lead screw 8 is in contact with the clamping block 7, and the other end of the lead screw 8 is fixedly connected to the disc 9. The rocker arm 10 is installed at the outer edge of the disc 9.

[0026] By setting lead screws 8 at both ends of the limiting plate 2, the disk 9 is driven to rotate by the rocker arm 10. When the lead screw 8 rotates, it pushes the clamping block 7 close to the screw machine body 1, which facilitates the assembly of the limiting plate 2 and the screw machine body 1.

[0027] Reference Figure 1 , Figure 2 and Figure 3 As one embodiment of this utility model, specifically, a rectangular groove 4 is provided at the end of the limiting plate 2 at the top position of the clamping block 7, and symmetrical sliding rods 6 are fixedly connected to the inner wall of the rectangular groove 4. A slider 5 is slidably connected to the surface of the sliding rod 6, and the clamping block 7 is fixedly connected to the bottom of the slider 5.

[0028] A rectangular groove 4 is opened at the end of the limiting plate 2 to set the slide rod 6 to slide and connect the slider 5. The bottom of the slider 5 is connected to the clamping block 7 to support the stable lateral sliding of the clamping block 7.

[0029] Working principle: When the diameter of the carbon-carbon composite rod to be processed is small (e.g., less than 10mm), place the limiting plate 2 at the top of the screw press body 1, rotate the rocker arms 10 at both ends of the limiting plate 2. The rocker arms 10 drive the disc 9 and the lead screw 8 to rotate. The lead screw 8 pushes the clamping block 7 close to the top of the screw press body 1 until both clamping blocks 7 are engaged at the top of the screw press body 1, completing the assembly of the limiting plate 2 and the screw press body 1. Then, first adjust the position of the arc plate 16 downwards. Specifically, first loosen the screw 13 outside the rectangular frame 15, slide the arc plate 16 downwards so that it is positioned below the installation position of the carbon-carbon composite rod. Next, the carbon-carbon composite rod is assembled with the screw press body 1. Then, the arc plate 16 is adjusted upward so that the pulley 17 in the middle position contacts the bottom of the carbon-carbon composite rod. Then, the position of the movable plate 14 is adjusted downward so that the pulley 17 in the middle position contacts the top of the carbon-carbon composite rod. Then, the screw 13 is tightened to fix the position of the movable plate 14 and the arc plate 16. Then, the screw press body 1 is started to process the carbon-carbon composite rod. During the processing, the movable plate 14 and the arc plate 16 provide support to the local position of the carbon-carbon composite rod through the pulley 17, which greatly reduces the bending of the carbon-carbon composite rod.
