DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below, obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor are involved in the protection scope of the utility model.

[0023] Reference Figures 1-6The application discloses an atmosphere lifting furnace, which comprises a rack 1, a furnace body 101 arranged on the top of the rack 1, a base 102 detachably fixed to the bottom of the furnace body 101, a sliding plate 108 arranged on the bottom of the base 102, a first pulley 103 and a second pulley 104 arranged on the bottom of the sliding plate 108, wherein the first pulley 103 and the second pulley 104 are arranged on the front side and the rear side of the sliding plate 108 respectively, and the first pulley 103 and the second pulley 104 are staggered, a lifting plate 105 arranged on the bottom of the rack 1, and a plurality of first sliding rails 106 arranged on the top of the lifting plate 105 and connected with the first pulley 103 and the second pulley 104 respectively, wherein the first sliding rails 106 are fixedly connected with the top of the lifting plate 105.

[0024] The rack 1 is fixedly connected with a second sliding rail 109 which has the same horizontal height as the first sliding rail 106, and the second sliding rail 109 has the same structure as the first sliding rail 106; a gap is arranged between the first sliding rail 106 and the second sliding rail 109, so that the lifting plate 105 can freely drive the first sliding rail 106 to move up and down; a positioning groove 107 is arranged on each first sliding rail 106 and connected with the first pulley 103 and the second pulley 104; and a jacking mechanism is arranged in each positioning groove 107 and used for making the bottom of the first pulley 103 and the second pulley 104 flush with the surface of the first sliding rail 106.

[0025] The first pulley 103, the second pulley 104, the first sliding rail 106 and the second sliding rail 109 are arranged, so that when the base 102 is separated from the furnace body 101, the jacking mechanism is started to make the first pulley 103 and the second pulley 104 separate from the positioning groove 107 and be on the surface of the first sliding rail 106; then the operator can pull the sliding plate 108 and pull it out along the direction of the first sliding rail 106 and the second sliding rail 109, so that the base 102 is separated from the bottom of the furnace body 101, and the operator has more operation space to replace the material.

[0026] In addition, the positioning groove 107 can make the operator accurately position the sliding plate 108 when the sliding plate 108 is pushed into the bottom of the furnace body 101, so that the time for alignment is reduced, and the work efficiency is improved.

[0027] Specifically, the jacking mechanism includes a jacking block 2, a sliding block 201, a connecting plate 202, and a telescopic driving mechanism 203 for pushing the sliding block 201 to move (the telescopic driving mechanism 203 can be a pneumatic cylinder, a hydraulic cylinder, or any mechanism that can push the sliding block 201 to move, and the present embodiment does not make too many limitations on this), the bottom of the lifting plate 105 is fixedly connected with the connecting plate 202 through a plurality of connecting blocks 204, the jacking block 2 is arranged in the positioning groove 107 and is in sliding connection with the inner wall of the positioning groove 107, and one end of the jacking block 2 extends to between the connecting plate 202 and the bottom plate, the shape of the jacking block 2 can be the same as that of the first sliding rail 106, the sliding block 201 is in sliding connection with the top of the connecting plate 202, the sliding block 201 is provided with a sliding groove 205, and the sliding groove 205 is arranged in an inclined manner, and the jacking block 2 is provided with a sliding column 206, and the sliding column 206 is in sliding connection with the inner wall of the sliding groove 205.

[0028] When the operator needs to pull the sliding plate 108, the telescopic driving mechanism 203 can be started, and the telescopic rod of the telescopic driving mechanism 203 drives the sliding block 201 to move on the surface of the connecting plate 202. At the same time, since the sliding groove 205 is arranged in an inclined manner and the jacking block 2 is arranged in the positioning groove 107 and is limited by the positioning groove 107, the jacking block 2 can only move in the vertical direction. Therefore, the sliding column 206 at the bottom of the jacking block 2 is gradually moved upward under the driving of the sliding groove 205, until the surface of the jacking block 2 is flush with the surface of the first sliding rail 106, so that the first pulley 103 and the second pulley 104 are separated from the positioning groove 107.

[0029] In order to reduce the blocking phenomenon of the sliding column 206 during movement, the sliding column 206 is designed as a whole in a cylindrical structure, and the sliding column 206 is rotatably connected with the jacking block 2. The cylindrical structure can reduce the contact area between the sliding column 206 and the sliding groove 205, thereby reducing friction and resistance, and making the movement of the sliding column 206 more smooth. At the same time, the rotatable connection between the sliding column 206 and the jacking block 2 enables the sliding column 206 to rotate during movement. The dynamic friction is usually smaller than the static friction, thereby further reducing the blocking phenomenon and improving the reliability and stability of the jacking mechanism during long-term use.

[0030] In addition, in order to prevent the sliding block 201 from deviating or misplacing during movement, a limiting groove 207 is arranged at the bottom of the sliding block 201, and a limiting block 208 is arranged at the top of the connecting plate 202, the limiting block 208 is in sliding connection with the inner wall of the limiting groove 207, and the limiting block and the limiting groove 107 can limit the degrees of freedom of the sliding block 201, so that the sliding block 201 can only move in the direction of the limiting block, thereby ensuring that the sliding block 201 will not deviate during movement, and further improving the reliability and stability of the jacking mechanism during long-term use.

[0031] Further, the lifting mechanism comprises lead screws 3 arranged at four corners of the lifting plate 105, synchronous pulleys 301 fixedly connected with the lead screws 3 respectively, a first synchronous belt 302 connecting the synchronous pulleys 301, and a rotary motor 303 driving the lead screws to rotate, wherein each lead screw 3 is threadedly connected with the lifting plate 105, the two sides of each lead screw 3 are rotationally connected with the rack 1, the rotary motor 303 is arranged at the top of the rack 1 and fixedly connected with the rack 1, and the output end of the rotary motor 303 is fixedly connected with one of the lead screws 3. The rotary motor 303 can be fixedly connected with the top of the rack 1 through a fixing plate.

[0032] When the operator needs to combine the base 102 with the furnace body 101, the rotary motor 303 is started, the output end of the rotary motor 303 drives the lead screw to rotate, and in turn drives the synchronous pulley 301 to rotate. The synchronous pulley 301 drives the synchronous pulleys 301 on the lead screws 3 to rotate through the first synchronous belt 302, and the rotation of the lead screws 3 drives the lifting plate 105 to rise. Since the first pulley 103 and the second pulley 104 at the bottom of the sliding plate 108 are clamped in the positioning groove 107, the sliding plate 108 cannot move, but rises together with the lifting plate 105. At the same time, the sliding plate 108 also drives the base 102 to rise, until the base 102 is combined with the furnace body 101 (it should be noted that the weight of the sliding plate 108, the base 102 and the workpiece to be heated can make the first pulley 103 and the second pulley 104 stably press in the positioning groove 107, so that they are not easy to shake. If the fixing efficiency needs to be improved, an electromagnetic structure can be arranged between the first sliding rail 106 and the sliding plate 108 to ensure stable fixing effect). The lead screw transmission has self-locking property, which means that the lead screw 3 will not move in the opposite direction without external driving force. Even if the furnace body 101 is in a heating state for a long time, the base 102 and the sliding plate 108 will not slide down due to gravity, thereby effectively preventing the accidental falling of the base 102, the sliding plate 108 and the lifting plate 105, and ensuring the safety of the system.

[0033] In the embodiment, guide rods 304 are fixedly connected with the rack 1 at opposite sides, and the lifting plate 105 is slidingly connected with the guide rods 304. By arranging the guide rods 304, the lifting plate 105 can be prevented from deviating or misplacing during movement, thereby ensuring the accurate positioning of the base 102 and the furnace body 101.

[0034] In addition, the third slide rail 305 can be fixedly connected to the side of the rack 1 away from the second slide rail 109, and the horizontal height of the third slide rail 305 is the same as that of the first slide rail 106. By arranging the third slide rail 305, the operator can set a replacement part 4 with the same structure as the sliding plate 108 and the base 102 on the third slide rail 305 again. When in use, the operator can place a preheated workpiece on the surface of the replacement part 4 in advance. When the workpiece in the furnace body 101 is heated to completion, the operator starts the rotary motor 303, lowers the lifting plate 105, and separates the base 102 from the furnace body 101. Then, the sliding plate 108 is pulled and moved to the surface of the second slide rail 109, and then the replacement part 4 is pushed from the surface of the third slide rail 305 to the surface of the first slide rail 106, and the first pulley 103 and the second pulley 104 are clamped with the positioning groove 107. Finally, the rotary motor 303 is started to drive the replacement part 4 to combine with the furnace body 101. Through this process, the time for the operator to replace the workpiece is reduced, and the work efficiency is improved. The first pulley 103 and the second pulley 104 are staggered to ensure that the two pulleys of the sliding plate 108 can be clamped at the same position when moving to the bottom of the furnace body 101 from different directions, thereby ensuring the accurate positioning between the base 102 and the furnace body 101.

[0035] Working principle:

[0036] When the operator needs to take the material, the fixing between the base 102 and the furnace body 101 is released, and then the rotary motor 303 is started. The output end of the rotary motor 303 drives the screw rod to rotate, and then drives the synchronous pulley 301 to rotate. The synchronous pulley 301 drives the synchronous pulleys 301 on the screw rods 3 to rotate through the first synchronous belt 302. The rotation of the screw rods 3 drives the lifting plate 105 to descend, and the lifting plate 105 drives the base 102 to descend. When the lifting plate 105 moves to the specified position, the telescopic drive mechanism 203 is started. The telescopic rod of the telescopic drive mechanism 203 drives the sliding block 201 to move on the surface of the connecting plate 202. At the same time, since the sliding groove 205 is inclinedly arranged, and the jacking block 2 is arranged in the positioning groove 107 and is limited by the positioning groove 107, the jacking block 2 can only move in the vertical direction. Therefore, the sliding column 206 at the bottom of the jacking block 2 is gradually moved upward under the drive of the sliding groove 205, until the surface of the jacking block 2 is flush with the surface of the first slide rail 106, so that the first pulley 103 and the second pulley 104 are separated from the positioning groove 107. Finally, the operator pulls the sliding plate 108 and pulls the sliding plate 108 to the surface of the second slide rail 109 to take the material.

[0037] When the taking material is completed, the operator pushes the sliding plate 108 into the bottom of the furnace body 101 along the second slide rail 109, and makes the first pulley 103 and the second pulley 104 be clamped with the positioning groove 107, then starts the rotating motor 303, the output end of the rotating motor 303 drives the screw rod to rotate, and then drives the synchronous pulley 301 to rotate. The synchronous pulley 301 drives the synchronous pulley 301 on each screw rod 3 to rotate through the first synchronous belt 302, and the rotation of the screw rod 3 makes the lifting plate 105 ascend. Since the first pulley 103 and the second pulley 104 at the bottom of the sliding plate 108 are clamped in the positioning groove 107, the sliding plate 108 will not move, but will ascend together with the lifting plate 105. At the same time, the sliding plate 108 also drives the base 102 to ascend, until the base 102 is combined with the furnace body 101.

[0038] The above is only a preferred embodiment of the present application, and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
