Description
Technical Field
[0001] This utility model relates to the field of center frame technology for reclining cars, specifically a burn protection kit for reclining car center frames. Background Technology
[0002] A lathe center rest is an auxiliary device used to radially support rotating workpieces during machining. It does not move axially relative to the workpiece during machining. A lathe center rest typically consists of a central support and two symmetrically distributed diagonal supports on both sides. A lathe center rest anti-burn kit is a device used to prevent workpiece surface burns caused by excessive cutting force or insufficient cooling during turning. This kit usually includes special materials or coatings designed to absorb and disperse cutting heat and improve lubrication conditions, thereby protecting the workpiece surface from thermal damage.
[0003] The design of the anti-burn kit for the center rest of the lathe is mainly to prevent burns or damage to the contact area between the workpiece and the center rest during the turning process due to friction, high pressure and heat concentration. Burns usually occur in the area where the workpiece is in direct contact with the center rest.
[0004] Heat transfer is the spontaneous transfer of heat from a high-temperature area to a low-temperature area whenever there is a temperature difference within or between objects. During turning, the heat generated in the contact area between the workpiece and the tool is transferred to the center rest through heat conduction. Continuous heat transfer may lead to a decrease in the strength and hardness of the center rest material, affecting its stability and accuracy in supporting the workpiece. Therefore, a burn-proof kit for the center rest of a horizontal lathe is proposed to address the above problems. Utility Model Content

[0027] Please see Figure 1-5 This utility model provides a technical solution:
[0028] A burn protection kit for a horizontal car center frame includes a frame platform 1 and a rail plate 2. The rail plate 2 is fixedly connected to the top of the frame platform 1, and a hydraulic rod 3 is fixedly connected to the inner side of the rail plate 2. A frame assembly 4 is fixedly connected to one side of the hydraulic rod 3. A heat-absorbing roller assembly 5 is rotatably connected to the inner side of the frame assembly 4. The frame assembly 4 includes a movable platform 41, a rail groove 42 is formed on the inner side of the movable platform 41, and a slant plate frame 43 is fixedly connected to the top of the movable platform 41. A shaft hole 44 is formed on the inner side of the slant plate frame 43, and a baffle 45 is fixedly connected to the slant plate frame 43 by fixing bolts 46. The heat-absorbing roller assembly 5 includes a roller 51, a heat-conducting groove 52 is provided on the inner side of the roller 51, an internally threaded cylinder 53 is fixedly connected to the front and rear ends of the roller 51, a bearing 54 is fixedly connected to the outer side of the internally threaded cylinder 53, a screw cylinder 55 is spirally fitted to the inner side of the internally threaded cylinder 53, a filter plate 56 is fixedly connected to the inner side of the screw cylinder 55, an aluminum alloy plate 57 is fixedly connected to the inner side of the heat-conducting groove 52 of the roller 51, a ventilation hole 58 is provided on the inner side of the aluminum alloy plate 57, and a fan blade 59 is fixedly connected to the inner side of the heat-conducting groove 52 of the roller 51.
[0029] As a further implementation of this scheme, there are two hydraulic rods 3. The inner side of the rail plate 2 is hollow. The rail plate 2 is slidably connected to the movable table 41 through the rail groove 42. One side of the movable table 41 is fixedly connected to one end of the hydraulic rod 3. The rail groove 42 passes through the inner side of the movable table 41. The rail groove 42 is opened on the inner side of the front end and the inner side of the rear end of the movable table 41. A connecting plate is fixedly connected to the middle of the lower end of the movable table 41, which serves to limit the movement of the movable table 41. The distance between the two frame components 4 can be adjusted according to the size of the cylindrical workpiece.
[0030] As a further implementation of this solution, the shaft hole 44 is shaped as a three-section cylinder, penetrating the interior of the inclined plate frame 43. There are two sets of inclined plate frames 43, with two frames in each set. The inclined plate frame 43 has a threaded hole on its inner side near the fixing bolt 46. The baffle 45 also has a threaded hole on its inner side near the fixing bolt 46. One side of the baffle 45 fits against one side of the inclined plate frame 43. The shaft hole 44 is opened on the inner side of the baffle 45. The bearing 54 is embedded in the shaft hole 44 of the inclined plate frame 43 and the shaft hole 44 of the baffle 45. This facilitates the stable rotation of the internal threaded cylinder 53 inside the shaft hole 44. By disassembling the fixing bolt 46, the filter plate 56 can be easily replaced and the heat absorption roller assembly 5 can be maintained as a whole, ensuring long-term effective operation and easy maintenance.
[0031] As a further implementation of this solution, the roller 51 is a hollow cylinder with through-type structures at both the front and rear ends. Threaded holes are provided on the inner side of the internally threaded cylinder 53. The internally threaded cylinder 53 is fixed at both the front and rear ends of the roller 51. The number of internally threaded cylinders 53 is the same as the number of screw cylinders 55. Threaded holes are provided on the outer side of the screw cylinder 55, and the inner side of the screw cylinder 55 is hollow. The heat-conducting groove 52 is cylindrical in shape. The aluminum alloy plate 57 is a slotted cylinder. Fan blades 59 are located between multiple aluminum alloy plates 57. Ventilation holes 58 penetrate the interior of the aluminum alloy plates 57. The aluminum alloy plate 57 support structure in the kit not only improves the strength of the roller 51 but also plays a cooling role by absorbing heat, ensuring the stability and accuracy of the workpiece during processing. Through the airflow guided by the fan blades 59, the roller 51 and aluminum alloy plate 57 can be cooled quickly. The anti-burn kit significantly improves the performance and reliability of the horizontal lathe center frame in high-temperature working environments.
[0032] Workflow: When machining a cylindrical workpiece, it needs to be placed outside multiple rollers 51. Based on the size of the cylindrical workpiece, the distance between the two frame components 4 is adjusted. The hydraulic rod 3 is activated to move the movable table 41. The movable table 41 slides on the outside of the rail plate 2 via the rail groove 42, which limits its movement. After the distance between the two frame components 4 is adjusted, the cylindrical workpiece is placed outside the multiple rollers 51 for machining. During this process, the workpiece needs to rotate. High temperatures are generated during machining and transferred to the rollers 51. Multiple aluminum alloy plates 57 inside the rollers 51 provide support and increase their strength. The heat from the rollers 51 is transferred to the aluminum alloy plates 57, which absorb the heat, thus cooling the rollers 51. The rotation of the workpiece causes the rollers 51 to rotate. The bearing 54 rotates inside the shaft hole 44. The rotation of the roller 51 drives the fan blade 59 to rotate. When the fan blade 59 rotates, it draws in external air from inside the screw cylinder 55. The air is filtered by the filter plate 56, which prevents impurities from entering the heat conduction groove 52. The screw cylinder 55 and the internal threaded cylinder 53 are detachable, making it easy to replace the filter plate 56 in a timely manner. After the external air enters the heat conduction groove 52, it flows out through the ventilation holes 58 opened inside the aluminum alloy plate 57. This dissipates heat from the heat conduction groove 52 and the aluminum alloy plate 57. The air then flows out from inside the screw cylinder 55 at the rear end, cooling the roller 51. This prevents the heat from the workpiece from causing the horizontal center frame to lose strength and hardness due to continuous heat, ensuring the stability of the workpiece support. The heat-absorbing roller assembly 5 can be removed as a whole by disassembling the fixing bolts 46, facilitating future maintenance of the heat-absorbing roller assembly 5.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
