Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a guide rail of a vacuum quenching furnace. Background Technique

[0002] The vacuum quenching furnace is mainly used to strengthen the surface of some metal equipment and has a wide range of applications in fine technologies such as aviation. Gas quenching means that after the workpiece is heated in a vacuum, a high-purity neutral gas is filled into the cooling chamber for cooling.

[0003] According to a vacuum quenching furnace with an internal waste heat recovery module with the publication number of CN216838091U, it solves the problems in the prior art that the quality of the vacuum quenching furnace is too large and usually requires large lifting equipment to be carried, but the lifting equipment in the workshop is not easy to enter and exit, thus affecting the handling work of the vacuum quenching furnace, etc. It includes a furnace body. A set of rollers are arranged on both sides of the bottom surface of the furnace body. A moving mechanism is arranged on the bottom surface of the rollers. An air quenching tank is arranged at the front end inside the furnace body. And a water tank is arranged at one end of the top surface of the furnace body. A water pump I is arranged at the bottom end of the water tank. One end of the water pump I is provided with a water guide pipe. One end of the water guide pipe is provided with a water pump II. Water valves are arranged at both the upper and lower ends on one side of the water tank. The moving mechanism includes two slide rails and a support frame. Jacks are arranged at both ends on one side of the support frame. And electric telescopic rods are arranged at both ends on the other side of the support frame.

[0004] To sum up, it can be seen that the following technical problems exist in the prior art: The guide rails of the vacuum quenching furnace in the above technology are fixedly spliced by bolts. Although this connection method can ensure the stability of the connection, in the actual operation process, it often requires screwing multiple bolts to achieve the fixed splicing between the guide rails. The splicing efficiency of the guide rails is low. Moreover, in order to save costs, the manufacturer often does not prepare many guide rails for standby. When it is necessary to move the vacuum quenching furnace to a long distance, the staff needs to frequently disassemble and assemble the two spliced guide rails. Therefore, the staff needs to disassemble and install the bolts for fixing the guide rails many times, and the operation is relatively cumbersome, and the practical performance of the device is not good.

[0005] On the other hand, since the jacking length of the jack is related to the stroke distance of the piston inside the jack, if the vacuum gas quenching furnace needs to be pushed a relatively long distance at one time, a jack with a relatively large volume is required to push the vacuum gas quenching furnace. Due to the relatively large weight and occupied area of the jack with a relatively large volume, it is inconvenient to install and use, and the cost of the jack with a relatively large volume is also relatively high, which is not conducive to the market promotion of the product. Moreover, if a jack with a relatively small volume is used to push the vacuum gas quenching furnace, it can only push the vacuum gas quenching furnace to move a relatively small distance on the guide rail at one time. When the distance that the vacuum gas quenching furnace needs to move is relatively long, the staff needs to frequently start and close the jack and the electric telescopic rod to push the vacuum gas quenching furnace multiple times before the vacuum gas quenching furnace can be moved to the designated position, which results in a relatively low moving efficiency of the vacuum gas quenching furnace and poor actual use effect of the device.

[0006] Therefore, we designed a guide rail for the vacuum gas quenching furnace to provide another technical solution to the above technical problems. Utility Model Content

[0012] Preferably, one end of the splicing plug close to the splicing slot is designed in a tapered shape with a narrow front and a wide rear. A plurality of second balls facilitating the movement of the splicing plug are rotatably connected to the bottom of the splicing slot.

[0029] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0030] Embodiment

[0031] Referring to Figures 1-7 , a vacuum quenching furnace guide rail includes a vacuum quenching furnace main body 1, a cooling device main body 2 and a guide rail 3. The vacuum quenching furnace main body 1 is movably arranged on the guide rail 3. The cooling device main body 2 is arranged on one side of the vacuum quenching furnace main body 1. The guide rail 3 is respectively arranged on both sides of the bottom of the vacuum quenching furnace main body 1. The guide rail 3 is divided into a first guide rail 4 and a second guide rail 5. The first guide rail 4 and the second guide rail 5 are provided with a splicing component for facilitating the splicing of the first guide rail 4 and the second guide rail 5. The bottom end of the vacuum quenching furnace main body 1 is fixedly connected with a plurality of universal brake casters 6. The vacuum quenching furnace main body 1 is slidably arranged on the guide rail 3 through the universal brake casters 6. The vacuum quenching furnace main body 1 and the guide rail 3 are provided with a moving component for facilitating the movement of the vacuum quenching furnace main body 1.

[0032] Through the design of the splicing component, the traditional fixed method of bolt connection is abandoned. When the staff splices the guide rail 3, only the splicing ends of the two guide rails 3 need to be inserted into each other, and the convenient splicing between the two guide rails 3 can be completed, thereby simplifying the operation process of splicing the guide rail 3 and improving the practical performance of the device.

[0033] Referring to Figures 2-4, the splicing component includes a splicing plug 7 fixedly arranged at one end of a first guide rail 4 and a second guide rail 5. Splicing slots 8 matching the splicing plug 7 are formed at the other ends of the first guide rail 4 and the second guide rail 5. Fixed insertion rods 9 for fixing the first guide rail 4 and the second guide rail 5 are arranged on both sides of the splicing slots 8. Fixed slots 10 matching the fixed insertion rods 9 are formed on the splicing plug 7. Mounting holes 11 communicating with the splicing slots 8 are formed on the first guide rail 4 and the second guide rail 5. An abutting ring 12 is fixedly arranged on one side of the fixed insertion rod 9 close to the splicing slot 8. A compression spring 13 is arranged on the side of the abutting ring 12 away from the splicing slot 8. Two ends of the compression spring 13 are respectively fixedly connected with the abutting ring 12 and the inner wall of the mounting hole 11. A handle 14 convenient for pulling is fixedly connected to one side of the fixed insertion rod 9. Specifically, through the design of the splicing plug 7, the splicing slot 8, the fixed insertion rod 9, the fixed slot 10, the mounting hole 11, the abutting ring 12, the compression spring 13 and the handle 14, when the staff splices the first guide rail 4 and the second guide rail 5, only need to insert the splicing plug 7 on the second guide rail 5 into the first guide rail 4 along the splicing slot 8, then the fixed insertion rod 9 arranged on the first guide rail 4 can be extruded to drive the compression spring 13 to contract and the fixed insertion rod 9 to retract into the mounting hole 11. After the end of the splicing plug 7 abuts against the inner wall of the splicing slot 8, the end of the fixed insertion rod 9 is aligned with the fixed slot 10, and the fixed insertion rod 9 will pop outwards under the action of the compression spring 13 and insert into the fixed slot 10, thus completing the splicing of the first guide rail 4 and the second guide rail 5;

[0034] It should be noted that in the present utility model, the end of the fixed insertion rod 9 is designed as a quarter-disc shape and its arc surface is close to the second guide rail 5. Through this design, when the staff splices the first guide rail 4 and the second guide rail 5, during the splicing process, the end of the fixed insertion rod 9 can be extruded by the splicing plug 7, so that it retracts into the mounting hole 11, and after the fixed insertion rod 9 is aligned with the fixed slot 10, it can be inserted into the fixed slot 10 under the action of the compression spring 13, thus completing the convenient splicing of the first guide rail 4 and the second guide rail 5.

[0035] Refer to Figures 4-6, one of the handles 14 is rotatably connected with a connecting rod 15. Through grooves 16 facilitating the movement of the connecting rod 15 are provided on the first guide rail 4 and the second guide rail 5. One end of the connecting rod 15 is rotatably connected with a push plate 17 for pushing the other handle 14. A plurality of fixing blocks 18 are fixedly arranged on the first guide rail 4 and the second guide rail 5. The push plate 17 is rotatably connected to the fixing blocks 18 through a rotating shaft. A slider 19 is fixedly connected to the side of the push plate 17 away from the connecting rod 15. A plurality of first balls 20 are rotatably connected to the slider 19. A chute 21 matching the slider 19 and the first balls 20 is formed in the handle 14. The push plate 17 is clamped in the chute 21 through the slider 19 and the first balls 20. Specifically, through the design of the connecting rod 15, the through groove 16, the push plate 17, the fixing blocks 18, the slider 19, the first balls 20 and the chute 21, the staff only needs to pull one handle 14 to drive the handles 14 on both sides of the first guide rail 4 to perform synchronous outward expansion movement, so as to facilitate the staff to disassemble the first guide rail 4 and the second guide rail 5. When it is necessary to disassemble the first guide rail 4 and the second guide rail 5, the staff only needs to pull one of the handles 14 with one hand, and can drive one side of the push plate 17 to pull along the fixing block 18 through the connecting rod 15 rotatably connected to the handle 14, so that the slider 19 and the first balls 20 on the other side of the push plate 17 move along the chute 21 formed in the other handle 14, and push the other handle 14 outwards, so that the fixed insertion rods 9 fixedly connected to the two handles 14 are pulled out of the fixed insertion slots 10. When the fixed insertion rod 9 is completely pulled out of the fixed insertion slot 10, the staff can pull out the second guide rail 5 from the first guide rail 4 with the other hand, thus completing the convenient disassembly of the first guide rail 4 and the second guide rail 5.

[0036] Refer to Figures 4-6 , one end of the splicing plug 7 close to the splicing slot 8 is designed in a tapered shape with a narrow front and a wide rear. A plurality of second balls 22 facilitating the movement of the splicing plug 7 are rotatably connected to the bottom of the splicing slot 8. Specifically, in the present utility model, through this design, the jamming during the splicing process of the first guide rail 4 and the second guide rail 5 is effectively avoided, the smoothness during the splicing of the first guide rail 4 and the second guide rail 5 is improved, and the actual use effect of the device is effectively enhanced.

[0037] Refer to Figure 7, the moving component includes a rack 23 fixedly arranged outside the guide rail 3. A gear 24 is engaged with the rack 23. The top end of the gear 24 is fixedly connected to a first transmission shaft 25. The bottom end of the vacuum quenching furnace main body 1 is fixedly connected to a first mounting plate 26. The first transmission shaft 25 is rotatably connected to the first mounting plate 26. A driven gear 27 is fixedly connected to one side of the first transmission shaft 25 close to the first mounting plate 26. A driving gear 28 is engaged with the driven gear 27. The middle of the driving gear 28 is fixedly connected to a second transmission shaft 29. The bottom end of the second transmission shaft 29 is rotatably connected to the bottom wall of the vacuum quenching furnace main body 1;

[0038] A second mounting plate 30 is arranged at the top end of one of the second transmission shafts 29. The second mounting plate 30 is fixedly arranged on the vacuum quenching furnace main body 1. A driving motor 31 is fixedly arranged at the top end of the second mounting plate 30. The output end of the driving motor 31 penetrates through the second mounting plate 30 and is fixedly connected to the second transmission shaft 29. One side of the top ends of multiple first transmission shafts 25 is fixedly connected to a synchronous pulley 32. A synchronous belt 33 for transmission is sleeved outside the synchronous pulley 32. Specifically, through the design of the moving component, it enables the staff to move the vacuum quenching furnace without using large-scale lifting equipment. At the same time, it optimizes the problems of high production cost or low moving efficiency existing in pushing the vacuum quenching furnace by using a jack and an electric telescopic rod, effectively improving the actual use effect of the device. Through the design of multiple synchronous pulleys 32 and synchronous belts 33, only one driving motor 31 is needed to drive multiple driving gears 28 to rotate, effectively reducing the actual production cost of the device and improving the market competitiveness of the device;

[0039] When carrying the vacuum gas quenching furnace, the staff first disassemble the cooling device main body 2 from the vacuum gas quenching furnace main body 1. Then, the staff connect the second guide rail 5 with the first guide rail 4, and lift up the brake pads on multiple universal braking casters 6. Then, start the driving motor 31 to drive the second transmission shaft 29 to rotate, and drive multiple driving gears 28 to rotate synchronously through the synchronous belt pulleys 32 and the synchronous belt 33 arranged on the second transmission shaft 29, so as to drive the driven gears 27 engaged with the driving gears 28 to rotate, and drive the first transmission shaft 25 fixedly connected to the driven gears 27 to rotate, so that the gear 24 fixedly connected to the bottom end of the first transmission shaft 25 rotates and continuously drives the vacuum gas quenching furnace to move on the first guide rail 4 and the second guide rail 5 during the meshing with the rack 23. When the vacuum gas quenching furnace moves to the end of the second guide rail 5, if the vacuum gas quenching furnace still has not been moved to the designated position, it is necessary to stop the driving motor 31 and remove the first guide rail 4 from the second guide rail 5, insert the splicing plug 7 fixedly arranged at one end of the first guide rail 4 into the splicing slot 8 opened at one end of the second guide rail 5, and then start the driving motor 31 to continue driving the vacuum gas quenching furnace to move forward along the first guide rail 4, and repeat the above operations in sequence until the vacuum gas quenching furnace moves to the designated position. Then, remove the first guide rail 4 or the second guide rail 5, and step on the brake pads of the universal braking casters 6 to death, and the handling of the vacuum gas quenching furnace can be completed.

[0040] It should be noted that in the present utility model, in order to increase the output torque of the driving motor 31, a speed reducer box is fixedly connected to the output end of the driving motor 31. Through this design, the output torque of the driving motor 31 is increased, so as to avoid the phenomenon that the driving motor 31 cannot drive the vacuum gas quenching furnace to move on the guide rail 3, and effectively ensure the normal operation of the device.

[0041] Refer to Figures 1-3 And Figure 7 , on one side of the two opposite guide rails 3, a guide plate 34 for guiding the ground ox is fixedly connected. On the side of the guide plate 34 close to the ground ox, a plurality of third balls 35 are rotatably connected. Specifically, the guide plate 34 is designed in a wedge shape with a wider front and a narrower rear. Since most of the workpieces to be processed in the vacuum gas quenching furnace are transported by the ground ox and placed into the vacuum gas quenching furnace, the design of the guide plate 34 plays a certain guiding role in the process of putting the ground ox in, and at the same time, through the design of the third balls 35, the smoothness of inserting the ground ox can be effectively improved, and the actual use effect of the device can be improved.

[0042] The using process of a guide rail 3 of a vacuum gas quenching furnace provided by the present utility model is as follows:

[0043] When splicing the first guide rail 4 and the second guide rail 5, the staff only needs to insert the splicing insert block 7 on the second guide rail 5 into the first guide rail 4 along the splicing slot 8, so as to squeeze the fixed insertion rod 9 arranged on the first guide rail 4 to drive the compression spring 13 to contract and make the fixed insertion rod 9 retract into the installation hole 11. After the end of the splicing insert block 7 abuts against the inner wall of the splicing slot 8, the end of the fixed insertion rod 9 is aligned with the fixed slot 10, and the fixed insertion rod 9 will pop out outward under the action of the compression spring 13 and insert into the fixed slot 10, thus completing the splicing of the first guide rail 4 and the second guide rail 5;

[0044] When disassembling the first guide rail 4 and the second guide rail 5, the staff only needs to pull one of the handles 14 with one hand, and then drive the side of the push plate 17 to pull along the fixed block 18 through the connecting rod 15 rotatably connected to the handle 14, so that the slider 19 and the first ball 20 on the other side of the push plate 17 move along the chute 21 opened on the other handle 14, and push the other handle 14 outward, so that the fixed insertion rods 9 fixedly connected to the two handles 14 are pulled out of the fixed slot 10. When the fixed insertion rod 9 is completely pulled out of the fixed slot 10, the staff can pull out the second guide rail 5 from the first guide rail 4 with the other hand, thus completing the convenient disassembly of the first guide rail 4 and the second guide rail 5;

[0045] When carrying the vacuum quenching furnace, the staff first disassembles the cooling device main body 2 from the vacuum quenching furnace main body 1, then splices the second guide rail 5 and the first guide rail 4, and raises the brake pads on the plurality of universal brake casters 6 upward. Then start the driving motor 31 to drive the second transmission shaft 29 to rotate, and drive the plurality of driving gears 28 to rotate synchronously through the synchronous belt wheels 32 and the synchronous belt 33 arranged on the second transmission shaft 29, so as to drive the driven gears 27 engaged with the driving gears 28 to rotate, and drive the first transmission shaft 25 fixedly connected to the driven gears 27 to rotate, so that the gear 24 fixedly connected to the bottom end of the first transmission shaft 25 rotates and meshes with the rack 23, continuously driving the vacuum quenching furnace to move on the first guide rail 4 and the second guide rail 5. When the vacuum quenching furnace moves to the end of the second guide rail 5, if the vacuum quenching furnace has not been moved to the designated position, the driving motor 31 needs to be stopped and the first guide rail 4 is removed from the second guide rail 5, and the splicing insert block 7 fixedly arranged at one end of the first guide rail 4 is inserted into the splicing slot 8 opened at one end of the second guide rail 5. Then start the driving motor 31 to continue driving the vacuum quenching furnace to move forward along the first guide rail 4, and repeat the above operations in turn until the vacuum quenching furnace moves to the designated position. Then remove the first guide rail 4 or the second guide rail 5, and step on the brake pads of the universal brake casters 6 downward to complete the handling of the vacuum quenching furnace.
