Description

Technical Field

[0001] The utility model relates to a niobium alloy processing device, in particular to a niobium alloy surface treatment device. Background Art

[0002] In the aerospace field, niobium alloys are widely used in the manufacture of various key components due to their excellent physical and chemical properties, such as high melting point, good corrosion resistance, and high strength. Especially in the manufacture of high-precision and high-requirement aerospace equipment, the surface treatment of niobium alloy rod blanks is particularly important. Traditional belt cross-type polishing machines require manual loading and unloading when polishing niobium alloy rod blanks, while wheel-type polishing machines require the cooperation of chucks and mechanical jaws to assist in feeding and taking materials, which greatly delays the loading and unloading time, making the entire polishing process discontinuous and affecting production efficiency.

[0003] Therefore, there is an urgent need for an efficient niobium alloy surface treatment device, which has important practical significance and application value. Summary of the Utility Model

[0004] In order to overcome the shortcomings in the above background art, the utility model provides a niobium alloy surface treatment device with high polishing efficiency.

[0005] The technical solution is: a niobium alloy surface treatment device, including a frame, on which an intermittent feeding mechanism, a polishing mechanism, and a material receiving mechanism are provided; the polishing mechanism includes a fixed support, with a first rotating rod arranged at the upper end of the fixed support; a linear slide table, with a second rotating rod arranged at the upper end of the linear slide table, and the linear slide table can drive the second rotating rod to approach or move away from the first rotating rod. When the second rotating rod approaches the first rotating rod, the blank can be placed between the two and rotated. When the second rotating rod moves away from the first rotating rod, the blank drops from between the two to complete unloading; and a polishing wheel set, which can approach or move away from the first and second rotating rods; the material receiving mechanism is located below the first and second rotating rods and is inclined relative to the frame.

[0006] Further, the feeding mechanism includes a material tray arranged on the frame, the material tray is inclined towards the polishing mechanism, the blank is placed on the material tray and rolls by its own weight between the first and second rotating rods; a stepped boss is formed upward at one end of the bottom wall of the material tray close to the polishing mechanism for restricting the movement of the blank; a notch is provided on one side of the bottom wall of the material tray close to the boss, and a top plate that can extend upward along the notch is provided at the bottom of the notch. The top plate jacks up to lift the upper blank and make it roll down along the boss.

[0007] Further, the rotating direction of the polishing wheels in the polishing wheel set is the same as the rotating direction of the first and second rotating rods.

[0008] Further, the blank receiving mechanism includes a blank discharging plate body disposed on the frame. A long strip hole penetrating the bottom surface of the blank discharging plate body is provided thereon. The debris generated by polishing slides along the blank discharging plate body to the long strip hole and drops out. The size of the long strip hole is smaller than the size of the blank.

[0009] Further, a pull-out ash box is provided at the bottom of the long strip hole for collecting the dropped debris.

[0010] Further, the blank discharging plate body is connected to the frame by a hinge shaft. The hinge shaft is provided with an external thread and is fitted with a locking nut.

[0011] Further, a blank receiving buffer plate is provided at the bottom of the second rotating roller. One side of the blank receiving buffer plate is hinged to the linear slide by a pin shaft. A torsion spring is provided on the pin shaft. The blank drops from between the first and second rotating rollers onto the blank receiving buffer plate, and the self-weight presses down to make the blank receiving buffer plate rotate along the pin shaft and incline towards the blank receiving mechanism.

[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. The present utility model uses the cooperation of the first rotating roller and the second rotating roller, and realizes the automatic clamping and releasing of the blank through the drive of the linear slide, avoiding the problems of jamming and incoherence in the loading and unloading of traditional polishing machines. At the same time, the design of the polishing wheel set makes the polishing process more continuous and efficient, greatly improving the overall processing efficiency.

[0014] 2. The intermittent feeding mechanism of the present utility model adopts the design of an inclined material tray and stepped bosses, and cooperates with the telescopic top plate to realize the automatic rolling and positioning of the blank, simplifying the feeding process and improving the degree of automation. At the same time, this design can also effectively prevent the dislocation and damage of the blank during the transmission process.

[0015] 3. The blank receiving mechanism of the present utility model adopts the design of an inclined blank discharging plate body and long strip holes, which is convenient for the collection and discharge of polishing debris. The setting of the pull-out ash box is more convenient for the cleaning and recycling of debris, improving the cleanliness of the production environment. In addition, the hinge shaft connection design between the blank discharging plate body and the frame allows the blank discharging angle to be adjusted according to actual needs, enhancing the flexibility and practicability of the blank receiving mechanism.

[0016] 4. The blank receiving buffer plate provided at the bottom of the second rotating roller of the present utility model and its hinged design with the linear slide not only effectively slows down the impact force when the blank drops, but also prevents the blank from bouncing and shifting during the blank receiving process, further improving the stability and safety of the overall device.

Detailed implementation manners

[0024] The following will further illustrate the present utility model in combination with specific embodiments. It should also be noted that unless otherwise clearly specified and defined, terms such as: setting, installation, connection, and coupling should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations. The following will describe the implementation manners of the present utility model with reference to the drawings.

[0025] As Figure 1-2The niobium alloy surface treatment device shown specifically includes a frame 1. The frame 1 has a certain height, including an upper end face and support legs. An upper feeding mechanism 2, a polishing mechanism 3, and a receiving mechanism 4 are arranged on the upper end face of the frame 1. Among them, the polishing mechanism 3 includes a fixed support 31, a moving support 37, and a polishing wheel set 35. A first rotating rod 32 is arranged at the upper end of the fixed support 31, and a second rotating rod 34 is arranged at the upper end of the moving support 37. The first rotating rod 32 and the second rotating rod 34 together form a support and clamping part for placing and driving the blank to rotate. The first rotating rod 32 and the second rotating rod 34 have the same shape, both consisting of a rod-shaped structure and limiting structures arranged at both ends of the rod-shaped structure. The overall length should match the length of the blank. The second rotating rod 34 is movable relative to the first rotating rod 32. That is, the support 37 for supporting the second rotating rod 34 is installed on a linear slide 33, and the linear slide 33 can drive the second rotating rod 34 to approach or move away from the first rotating rod 32. When the second rotating rod 34 approaches the first rotating rod 32, the clearance distance between the second rotating rod 34 and the first rotating rod 32 becomes smaller, less than the diameter of the blank, so the blank can be placed between the two and rotated. When the second rotating rod 34 moves away from the first rotating rod 32, the clearance distance between the second rotating rod 34 and the first rotating rod 32 becomes larger, making the clearance greater than the diameter of the blank, and the processed blank falls from between the two to complete unloading. The polishing wheel set 35 is arranged above the first rotating rod 32 and the second rotating rod 34 and can approach or move away from the first rotating rod 32 and the second rotating rod 34. When approaching, it polishes the blank, and when moving away, it can perform the blank unloading operation.

[0026] The upper feeding mechanism 2 is located on one side of the polishing mechanism 3 and is used for continuous intermittent feeding to ensure the continuity of processing. The receiving mechanism 4 is arranged below the first rotating rod 32 and the second rotating rod 34 and is inclined relative to the frame 1. The processed blanks falling from between the first rotating rod 32 and the second rotating rod 34 will fall onto the receiving mechanism 4 and be collected.

[0027] The feeding, processing, and discharging processes of this device are very coherent. The first rotating rod 32 and the second rotating rod 34 cooperate to realize the automatic clamping and release of the blank through the drive of the linear slide 33, avoiding the problems of jamming and incoherence in loading and unloading in traditional polishing machines.

[0028] In a specific embodiment, the first rotating rod 32 and the second rotating rod 34 are respectively driven by a driving motor 36, and the driving motors 36 are respectively installed on the fixed support 31 and the moving support 37. The linear slide 33 includes a first slide rail 331, a first slider 332 and a first cylinder 333. The first slide rail 331 is fixedly arranged on the upper end surface of the frame. The first slider 332 is installed on the first slide rail 331, and the moving support 37 is fixedly arranged on the first slider 332. It should be noted that when a linear slide rail is adopted, the setting direction of the first slide rail 331 is perpendicular to the setting direction of the first rotating rod 32 or the second rotating rod 34. In addition, the first cylinder 333 can be replaced by an electric push rod, a lead screw mechanism or a linear motor, etc. All of the above fall within the protection scope of the present utility model.

[0029] Reference Figure 1 、 Figure 2 And Figure 4 , in a preferred embodiment, the device further includes a receiving buffer plate 5. The receiving buffer plate 5 is arranged at the bottom of the second rotating rod 34. Specifically, one side of the receiving buffer plate 5 is hinged to the linear slide 33 through a pin shaft 51, and a torsion spring 52 is arranged on the pin shaft 51. The blank between the first rotating rod 32 and the second rotating rod 34 will fall onto the receiving buffer plate 5. Due to its own weight, the receiving buffer plate 5 is pressed down to slowly rotate along the pin shaft 51 and tilt towards the receiving mechanism 4. At this time, the torsion spring 52 rotates and stores energy. The blank will be transferred from the receiving buffer plate 5 to the receiving mechanism 4, and then the receiving buffer plate 5 is reset by relying on the torsion spring 52. The setting of the receiving buffer plate 5 can effectively reduce the impact force when the blank falls, and also prevent the blank from bouncing and shifting during the receiving process, further improving the stability and safety of the overall device.

[0030] Specific reference Figure 3The polishing wheel assembly 35 specifically includes a vertical bracket 351, a second slide rail 352, a second slider 353, a second cylinder 354, a fixed guard plate 355, a polishing wheel 356 and a motor 357. Specifically in this embodiment, the vertical bracket 351 is fixed to the upper end of the fixed support 31, the second slide rail 352 is vertically arranged on the side of the vertical bracket 351, the second slider 353 is arranged on the second slide rail 352, the fixed guard plate 355 is fixed on the second slider 353 and slides synchronously with the second slider 353. The fixed guard plate 355 is used to install the polishing wheel. The motor 357 is fixed to the fixed guard plate 355, and the motor 357 is connected to the polishing wheel 356 for driving the polishing wheel 356 to rotate. The second cylinder 354 is fixed vertically to the vertical bracket 351, and the piston rod of the second cylinder 354 is downward and connected to the vertical bracket 351. The second cylinder 354 drives the polishing wheel 356 to approach the blank placed on the first rotating roller 32 and the second rotating roller 34 to complete the polishing. After the polishing is completed, the second cylinder 354 will drive the polishing wheel 356 away from the first rotating roller 32 and the second rotating roller 34. It should be noted that the rotation direction of the polishing wheel 356 of the polishing wheel assembly 35 is consistent with the rotation direction of the first and second rotating rollers 34.

[0031] like Figure 5 As shown, in a preferred embodiment, the loading mechanism 2 specifically includes: a material tray 21 arranged on the frame 1; the material tray 21 is inclined toward the side of the polishing mechanism 3, and the rod-shaped blank is placed on the material tray 21, and rolls down to between the first and second rotating rollers 34 by its own weight. In addition, a stepped boss 22 is formed upward at one end of the bottom wall of the material tray 21 close to the polishing mechanism 3, and the stepped boss 22 is used to limit the movement of the blank. A notch 23 is provided on the bottom wall of the material tray 21 close to the bottom end of the boss 22, and a top plate 24 is provided at the bottom of the notch 23 that can extend upward along the notch 23. The top plate 24 is pushed up so that the upper blank is lifted and rolls down along the boss 22.

[0032] The top plate 24 is driven by a third pneumatic cylinder 25 mounted on the upper end face of the frame 1. The movable rod of the third pneumatic cylinder 25 is connected to the top plate 24. When the movable rod extends, it drives the top plate 24 upward along the notch 23, lifting the blank at that position. The boss 22 no longer blocks the blank, and the blank, under its own weight, rolls down between the first and second rotating rollers 32 and 34 for processing. The loading mechanism 2, in conjunction with the polishing mechanism 3, enables rapid loading, unloading, and polishing, resulting in a very smooth and rapid processing flow.

[0033] Specific reference Figure 1 、 2 and Figure 6, the material receiving mechanism 4 specifically includes: a blanking plate body 41 arranged on the frame 1. A long strip hole 42 penetrating the bottom surface is provided on the blanking plate body 41. The debris generated by polishing will fall onto the blanking plate body 41. Then, through the vibration generated by the mechanical and electrical components of this device itself, the polishing debris slides along the blanking plate body 41 to the long strip hole 42 and falls. It should be noted that the size of the long strip hole 42 is much smaller than the size of the blank. In addition, a pull-out ash box 43 is provided at the bottom of the long strip hole 42 for collecting the fallen debris.

[0034] To adapt to the discharging of various different specifications, the blanking plate body 41 of this device is connected to the frame 1 by a hinge shaft 44. The hinge shaft 44 is provided with an external thread and is fitted with a locking nut 45. By adjusting the angle, the blanking speed and discharging direction of blanks of different sizes can be adapted. This enhances the flexibility and practicability of the material receiving mechanism 4.

[0035] The above embodiments only represent the preferred implementation modes of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations, improvements and substitutions can be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
