Description

Technical Field

[0001] This invention relates to the field of drum assembly technology, and in particular to a drum body electromagnetic induction heating and shaft threading device. Background Technology

[0002] Roller assembly is an important task in mechanical manufacturing and maintenance, involving the assembly of multiple components into a complete roller structure. Rollers are widely used in conveyors, printing presses, textile machinery, food processing equipment, and other fields. Their quality and performance directly affect the operating efficiency and reliability of the entire equipment. The roller body and shaft are interference fit. Before assembly, the roller body hole needs to be heated. Through thermal expansion and contraction, the hole is enlarged and the shaft is inserted. Due to the large volume of the roller body, the shaft is a through shaft. During heating, it needs to be placed horizontally. The simplest way to insert the shaft is to place the roller body vertically, lift the shaft, and insert it from top to bottom. After inserting the shaft, in order to place it stably, the roller body needs to be placed horizontally again. Due to the weight and volume of the roller body, and the need for multiple flipping during the assembly process, it is not convenient to flip it due to the influence of the roller body volume.

[0003] For example, Chinese Patent Application No. 202021823892.2 discloses a shaft sleeve that is easy to assemble, including a bearing housing, a bearing fixedly installed inside the bearing housing, and a shaft sleeve fixedly installed inside the bearing. This easily assembled shaft sleeve, through the arrangement of a connecting rod and a spring, achieves convenient installation and disassembly. Through the cooperation of a positioning hole and a positioning pin, a seesaw structure is formed during use due to the cooperation of the connecting rod and bolt. When the pressure block is pressed down, the connecting rod drives the positioning pin upward, thereby removing the positioning pin 13. Under the action of the limiting platform of the rotating shaft and the shaft sleeve, the rotating shaft is slid out. Conversely, when the pressure block is released, the spring pushes the pin at one end of the connecting rod downward, thereby inserting the positioning pin into the positioning hole for positioning and restriction. This achieves convenient installation and flexible axial adjustment, resulting in a simple structure and high practicality.

[0004] Although the invention makes the shaft easy to install and disassemble through the setting of connecting rods and springs, and through the matching of positioning holes and positioning pins, the assembly process of the shaft and cylinder requires an interference fit, which makes assembly difficult because the direct insertion method cannot heat and expand the cylinder.

[0005] To address these issues, this invention proposes a cylindrical electromagnetic induction heating and shaft-passing device. Summary of the Invention

[0006] The purpose of this invention is to provide a cylindrical electromagnetic induction heating and shaft-passing device that solves the problems mentioned in the background art through an obstacle avoidance mechanism and a drive mechanism.

Four sets of clamping blocks are slidably connected inside the outer frame. Heating fixtures are installed on the four sets of clamping blocks respectively.

[0012] Optionally, the docking frame is provided in four sets. Each of the four sets of docking frames has a shaft hole for rotatably connecting the telescopic cylinder. Two sets of docking frames are fixed to the support base frame with screws, and the other two sets of docking frames are fixed to the bottom of the tilting frame with screws. The fixed part and telescopic part of the two sets of telescopic cylinders used to control the tilting adjustment of the tilting frame are rotatably connected to the four sets of docking frames respectively.

[0013] Optionally, the hinge is provided in two sets, and the flip blades of the two sets of hinges are respectively fixed to the support base and the flip frame by screws.

[0014] Optionally, the inner wall of the plug-in support frame is provided with two sets of adjustment grooves for assisting the sliding connection, and the plug-in support frame is provided with a constraint groove for maintaining stability. The two sets of adjustment grooves and the constraint groove of the plug-in support frame are respectively slidably connected with telescopic baffles for supporting the cylinder body in the shaft mounting state.

[0015] Optionally, the bottom of the plug-in support frame is rotatably connected to two sets of hand control rods. The two sets of hand control rods are respectively threaded to control the adjustment of the telescopic baffle position, and the two sets of hand control rods are respectively threaded to the telescopic baffle.

[0016] Optionally, each set of base brackets is provided with two sets of displacement grooves for maintaining the stability of the displacement frame adjustment, and each set of base brackets is fixed with two sets of cylinders for controlling the position adjustment of the displacement frame. The telescopic rod of the cylinder is fixed to the displacement frame while extending and retracting in the displacement groove.

[0017] Optionally, each set of displacement frames is provided with a U-shaped frame for extending the moving distance. While the U-shaped frame of each set of displacement frames moves in the displacement groove, it remains connected to the cylinder. Each set of displacement frames is provided with a rectangular through hole for docking with the clamping frame.

[0018] Optionally, the outer fixing frame is provided in two sets, and both sets of outer fixing frames adopt a cross-shaped frame structure.

[0021] 1. This invention controls the tilting frame by controlling the extension and retraction of the telescopic cylinder, and maintains the stability of the tilting frame in the stopped state by the interstitial support block, thereby assisting in maintaining the stability of the cylinder. By threading the interstitial support block to the support base, the tilting frame assists in supporting the tilting frame and the telescopic baffle when the tilting frame completes the tilting motion, thereby filling the gap between the two sets of support base and facilitating the maintenance of the stability of the cylinder.

[0022] 2. After the cylinder port is heated, the present invention extends the telescopic baffle controlled by the hand control lever to support the cylinder after extension, and adjusts the relative state of the cylinder by flipping it with a flipping frame to adjust the cylinder from a horizontal state to a vertical state, which facilitates the subsequent assembly of the shaft. By setting the telescopic baffle to a telescopic state, obstruction is avoided when the displacement mechanism docks with the cylinder.

[0023] 3. The present invention supports the cylinder body through the bottom clamp frame to facilitate stability, and then pushes the displacement frame through the cylinder to drive the clamping frame to clamp the cylinder body, which facilitates the stability of the cylinder body. By setting the inclined sides on the bottom clamp frame and the clamping frame, the included angle between the inclined sides constrains the cylinder body, which facilitates the stability of the cylinder body.

[0024] 4. The present invention uses a displacement frame to fix the external frame, and at the same time, the displacement block assists the displacement mechanism to adjust the overall position. This makes it convenient for the heating fixture to contact the cylinder after the cylinder is fixed by extending and retracting the clamping block, and to move away in real time after heating is completed, so as to facilitate the heating treatment of the cylinder port.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example 1:

[0043] In practical use, it was found that the cylinder needs to be placed horizontally for heating. The simplest way to insert the shaft is to place the cylinder vertically, suspend the shaft, and insert it from top to bottom. However, after inserting the shaft, the cylinder needs to be placed horizontally again for stability. Due to the weight and volume of the cylinder, and the need for multiple flipping processes during assembly, the cylinder's volume makes flipping difficult. To solve the above problems, this embodiment was invented:

[0044] Please see Figure 7 As shown, the first embodiment of the present invention provides a cylindrical electromagnetic induction heating and shaft-passing device, including a flipping mechanism 1; the flipping mechanism 1 includes a support base 11 for supporting the entire device and the cylindrical body, and the support base 11 is provided with threaded grooves at equal intervals; a support block 102 is threadedly connected to the threaded hole of the support base 11; a flipping hinge 103 for rotational adjustment is fixed on the support base 11 by screws; it also includes a baffle mechanism 2, a clamping mechanism 3, and a displacement mechanism 4;

[0045] Please see Figure 8 and Figure 9 As shown, the baffle mechanism 2 includes a flip frame 21 that contacts the interbracing block 102, and the flip frame 21 is fixed to the flip hinge 103 by screws; a docking side groove 201 is provided on the side of the flip frame 21; a plug-in support 202 for auxiliary support of the cylinder in the shaft mounting state is fixed to the docking side groove 201 by screws.

[0046] Please see Figure 6 and Figure 10 As shown, the clamping mechanism 3 includes a mounting base plate 31 for mounting other structures of the clamping mechanism 3. The bottom of the mounting base plate 31 is fixedly connected to a locking block 301 for maintaining synchronous connection with the tilting frame 21. The top of the mounting base plate 31 is fixedly connected to a bottom bracket 302 for supporting and constraining the bottom of the cylinder. A displacement frame 305 is slidably connected to the bottom bracket 302. The top of the displacement frame 305 is fixed with a clamping frame 306 for clamping the cylinder by screws.

[0047] Please see Figure 5 and Figure 11 As shown, the displacement mechanism 4 includes a guide rail 41 for assisting the overall movement of the displacement mechanism 4. A displacement block 401 is slidably connected to the guide rail 41. A displacement frame 402 for installing other structures of the displacement mechanism 4 is fixed to the displacement block 401. An outer frame 403 is fixed to the displacement frame 402 by screws. Four sets of clamping blocks 405 are slidably connected inside the outer frame 403. Heating fixtures 406 are respectively installed on the four sets of clamping blocks 405.

[0048] Please see Figure 7 As shown, there are four sets of docking frames 101. Each of the four sets of docking frames 101 has a shaft hole for rotatably connecting the telescopic cylinder 104. Two sets of docking frames 101 are fixed to the support base 11 with screws, and the other two sets of docking frames 101 are fixed to the bottom of the flipping frame 21 with screws. The fixed and telescopic parts of the two sets of telescopic cylinders 104 used to control the flipping adjustment of the flipping frame 21 are rotatably connected to the four sets of docking frames 101. There are two sets of flipping hinges 103, and the flipping blades of the two sets of flipping hinges 103 are fixed to the support base 11 and the flipping frame 21 with screws, respectively. The flipping mechanism 1 is mainly controlled by controlling the extension and retraction of the telescopic cylinder 104. The tilting frame 21 is tilted, and the intermediate support block 102 keeps the tilting frame 21 stable in the stopped state to help maintain the stability of the cylinder; the support base frame 11 is mainly used to support other structures of the device to facilitate the overall stability of the device; the docking frame 101 is used to help fix the telescopic cylinder 104 to facilitate its adjustment; the intermediate support block 102 is used to support the tilting frame 21 to facilitate its stability after tilting; the tilting hinge 103 is used to assist the tilting frame 21 in tilting to facilitate the adjustment of the cylinder state; the telescopic cylinder 104 is used to control the tilting frame 21 to tilt under the control of external equipment to facilitate its use.

[0049] Please see Figure 8 and Figure 9As shown, the inner wall of the plug-in support 202 is provided with two sets of adjustment grooves 203 for assisting sliding connection. At the same time, the plug-in support 202 is provided with a constraint groove for maintaining stability. The two sets of adjustment grooves 203 and the constraint groove of the plug-in support 202 are respectively slidably connected with telescopic baffles 205 for supporting the cylinder in the shaft mounting state. The bottom of the plug-in support 202 is rotatably connected with two sets of hand control rods 204. The two sets of hand control rods 204 are respectively provided with threads for controlling the adjustment of the position of the telescopic baffles 205, and the two sets of hand control rods 204 are respectively threaded to the telescopic baffles 205. The baffle mechanism 2 is used to control the telescopic baffles 205 to extend after the cylinder port is heated, so as to support the cylinder after extension. The relative state of the cylinder is adjusted by flipping the rotating frame 21, so that the cylinder is adjusted from a horizontal state to a vertical state, which facilitates the subsequent assembly of the shaft.

[0050] Please see Figure 6 and Figure 10 As shown, each set of base brackets 302 has two sets of displacement grooves 303 for maintaining the stability of the displacement frame 305. Two sets of cylinders 304 for controlling the position adjustment of the displacement frame 305 are fixed to the outer wall of each set of base brackets 302. The telescopic rods of the cylinders 304 are fixed to the displacement frame 305 while extending and retracting within the displacement grooves 303. Each set of displacement frames 305 is provided with a U-shaped frame for extending the moving distance. The U-shaped frame of each set of displacement frames 305 remains connected to the cylinders 304 while moving within the displacement grooves 303. Each set of displacement frames 305 has a rectangular through hole for docking with the clamping frame 306. The clamping mechanism 3 supports the cylinder body through the base brackets 302 to maintain stability, and then pushes the displacement frame 305 through the cylinders 304. The clamping frame 306 clamps the cylinder to maintain its stability. The mounting base plate 31 supports other structures of the clamping mechanism 3 for supporting the cylinder. The locking block 301 connects the mounting base plate 31 to the tilting frame 21 for synchronous adjustment. The bottom clamping frame 302 works with the clamping frame 306 to clamp the cylinder and maintain its stability. The displacement groove 303 assists in installing the displacement frame 305 to maintain its stability. The cylinder 304 pushes the displacement frame 305 to control the clamping frame 306 for adjustment. The displacement frame 305 drives the clamping frame 306 to adjust its position. The clamping frame 306 works with the bottom clamping frame 302 to constrain the cylinder for ease of use.

[0051] In use, the cylinder is placed on the base frame 302 using hoisting equipment. Then, the cylinder 304 is activated to push the displacement frame 305, which in turn drives the clamping frame 306 to adjust its position. During the adjustment, the clamping frame 306 and the base frame 302 clamp the cylinder. After the cylinder port is heated, the hand control lever 204 is rotated to adjust the position of the telescopic baffle 205 in the adjustment groove 203 via the thread. The telescopic baffle 205 contacts the cylinder port. Then, the telescopic cylinder 104 is activated, and the rotating frame 21 is pushed during the telescopic process. The rotating hinge 103 is used to flip the cylinder, making it easy to adjust it from a horizontal to a vertical position for later assembly with the shaft.

[0052] In summary, the cylinder is supported and constrained by the flipping mechanism 1 and the clamping mechanism 3, which reduces the constraint on the cylinder. The relative state of the cylinder is adjusted by flipping, so as to facilitate the flipping process when assembling with the shaft. This reduces the influence of the cylinder volume on the flipping process and avoids the problem of the cylinder volume affecting the flipping process due to the need for multiple flipping processes during the assembly process.

[0053] Example 2

[0054] In use, the connection between the cylinder and shaft requires an interference fit assembly process, which makes assembly difficult. Direct insertion does not allow for heating and expansion of the cylinder, hindering assembly. To address this issue, this embodiment is invented:

[0055] Please see Figure 5 and Figure 11As shown, there are two sets of outer fixing frames 403, both of which adopt a cross-shaped frame structure. An inner binding block 404 is fixed inside the outer fixing frame 403 to maintain the stability of the clamping block 405. Four sets of cylindrical guide rods are provided on the inner binding block 404, and clamping springs are provided on each of the four clamping blocks 405 to provide clamping force. External components are provided inside each of the four clamping blocks 405, and these external components are electrically connected to the heating fixture 406 used for heating the cylinder. The displacement mechanism 4 is used to fix the outer fixing frame 403 via the displacement fixture 402, and simultaneously, in conjunction with the displacement block 401, assists the displacement mechanism 4 in adjusting its overall position, so that after the cylinder is fixed, the clamping blocks 405 can be extended... The heating fixture 406 is brought into contact with the cylinder and then moved away after heating to facilitate heating of the cylinder port. The guide rail 41 assists the displacement block 401 in adjusting the position of the displacement frame 402. The displacement block 401 assists in installing the displacement frame 402. The displacement frame 402, with the assistance of the displacement block 401, drives the heating fixture 406 to adjust its position. The outer fixing frame 403, in conjunction with the inner binding block 404, constrains the clamping block 405 and the heating fixture 406. The inner binding block 404, in conjunction with the outer fixing frame 403, constrains the clamping block 405 and the heating fixture 406. The clamping block 405 assists in installing the heating fixture 406. The heating fixture 406 is used for heating the cylinder port.

[0056] During use, after the cylinder is clamped, the displacement block 401 and guide rail 41 are used to assist in the position adjustment of the displacement frame 402, and the heating fixture 406 is brought closer to the cylinder port. Then, the sliding clamping block 405 is used to adjust the distance between them inside the outer frame 403, so that the heating fixture 406 contacts the cylinder port and the cylinder port is heated at the same time.

[0057] In summary, by adjusting the position of the displacement fixture 402, the heating fixture 406 is controlled to move closer to or further away from the cylinder. This facilitates the assembly of the cylinder port before assembling the cylinder and shaft, avoiding the problem that the cylinder and shaft need to meet the interference fit assembly process during the connection, and that the direct plug-in method cannot heat and expand the cylinder, making it inconvenient for assembly.

[0058] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
