Description

Technical Field

[0001] This utility model relates to an automatic tilting fixture for a bogie furnace. Background Technology

[0002] In industrial production, bogie hearth furnaces are commonly used for heat treatment of workpieces, such as quenching and annealing. Spherical and cylindrical workpieces are frequently subjected to this heat treatment. In these heat treatment processes, the workpieces need to be rotated to ensure uniform heating and improve the quality of the heat treatment.

[0003] Traditional flipping methods are mostly manual operations, which require removing the trolley from the furnace and then having operators wear heat-resistant gloves and use tools such as pliers and wrenches to directly clamp the workpiece for flipping. This operation is time-consuming and labor-intensive. Moreover, the surfaces of spherical and cylindrical workpieces are relatively smooth, making manual flipping inefficient and labor-intensive. In addition, operating in a high-temperature environment poses safety hazards.

[0004] In addition, spherical and cylindrical workpieces have relatively smooth surfaces, making it difficult to complete the flipping action stably. Furthermore, the waste generated during the heat treatment process is difficult to clean and tends to accumulate, affecting the processing quality of the workpieces.

[0005] Therefore, an automatic tilting fixture for bogie furnaces is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide an automatic turning fixture for bogie furnaces, so as to solve the problems mentioned in the background art that the traditional turning methods are mostly manual operations, with low turning efficiency and safety hazards.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an automatic tilting fixture for a bogie furnace, including a support seat placed on a bogie, a chip guide groove is opened in the middle of the support seat, and a drive roller and a follower roller are respectively arranged on both sides of the chip guide groove. The area between the drive roller and the follower roller is a workpiece placement area, so that the workpiece (spherical or cylindrical workpiece) is automatically tilted at the support seat by the drive roller and the follower roller.

[0008] Preferably, a heat insulation cover is connected to one side of the support seat by fixing bolts. A motor is installed inside the heat insulation cover. The output end of the motor is connected to the drive roller through a transmission component, so that the motor drives the drive roller to rotate through the transmission component.

[0009] Preferably, the transmission component includes an output shaft disposed at the output end of the motor, a drive gear disposed on the outer periphery of the output shaft, a driven gear meshing with the outer periphery of the drive gear, and the driven gear being connected to the input end of the drive roller shaft.

[0010] Preferably, multiple sets of anti-slip sleeves are provided on the outer periphery of both the drive roller and the follower roller, and the outer periphery of the anti-slip sleeves is provided in a toothed groove shape.

[0011] Preferably, the support seat is arranged in an arc shape on both sides of the chip guide groove so that the waste chips generated by the workpiece during heat treatment in the bogie furnace slide down to the chip guide groove via the arc surface.

[0012] Preferably, the bearing seat is provided with rotating grooves on both sides of the upper part of the chip guide groove for connecting the drive roller and the follower roller.

[0013] Preferably, the heat insulation cover is provided with a heat insulation plate inside so that the heat insulation cover blocks the heat inside the trolley furnace from being transferred to the motor.

[0014] Preferably, the distance between the drive roller and the follower roller is smaller than the diameter of the workpiece, so that the workpiece can be flipped on the drive roller and the follower roller.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention utilizes a motor-driven active roller, in conjunction with a follower roller, to automatically rotate spherical and cylindrical workpieces. This eliminates the need for manual rotation, significantly reducing operation time and improving the production efficiency of the trolley furnace.

[0017] To address the issue of smooth, slippery surfaces on spherical and cylindrical workpieces, toothed anti-slip sleeves are installed on the outer periphery of both the drive and follower rollers. During the flipping process, this effectively prevents workpiece slippage and displacement, ensuring stable flipping and improving the uniformity and stability of heat treatment quality.

[0018] The chip guide groove in the middle of the support and the arc-shaped design on both sides allow the waste chips generated during the heat treatment of spherical and cylindrical workpieces to slide smoothly into the chip guide groove and be collected. This facilitates the cleaning of waste chips, prevents their accumulation from affecting the workpiece processing quality and tooling service life, and maintains a clean working environment.

[0019] The heat shield and internal heat insulation panels effectively prevent the high-temperature heat inside the trolley furnace from being transferred to the motor, providing a good working environment for the motor. This reduces the possibility of motor damage due to overheating, extends the motor's service life, and lowers equipment maintenance costs and replacement frequency. Attached Figure Description

[0026] To address the problems of low efficiency and safety hazards associated with traditional manual tilting methods, this utility model provides an automatic tilting fixture for bogie furnaces. The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] Please see Figure 1-5 This utility model provides an automatic tilting fixture for a bogie hearth furnace, including a support seat 1 placed on a bogie. A chip guide groove 2 is formed in the middle of the support seat 1. A drive roller 3 and a follower roller 4 are respectively arranged on both sides of the chip guide groove 2. The support seat 1 is arc-shaped on both sides of the chip guide groove 2, so that waste chips generated during the heat treatment of the workpiece in the bogie hearth furnace slide down to the chip guide groove 2 via the arc-shaped surface. Rotation grooves 10 for connecting the drive roller 3 and the follower roller 4 are provided on both sides of the upper part of the support seat 1 in the chip guide groove 2. The distance between the drive roller 3 and the follower roller 4 is smaller than the diameter of the workpiece, so that the workpiece can be tilted on the drive roller 3 and the follower roller 4.

[0028] The area between the active roller 3 and the follower roller 4 is the workpiece placement area, so that the workpiece can be automatically flipped at the support seat 1 by the active roller 3 and the follower roller 4.

[0029] A heat insulation cover 6 is connected to one side of the support base 1 by fixing bolts 5. A motor 7 is installed inside the heat insulation cover 6. The output end of the motor 7 is connected to the drive roller 3 through a transmission component 8, so that the motor 7 drives the drive roller 3 to rotate through the transmission component 8. Multiple sets of anti-slip sleeves 9 are provided on the outer periphery of the drive roller 3 and the follower roller 4. The outer periphery of the anti-slip sleeves 9 is provided in a toothed groove shape.

[0030] The transmission component 8 includes an output shaft 81 disposed at the output end of the motor 7. A drive gear 82 is disposed on the outer periphery of the output shaft 81. A driven gear 83 is meshed on the outer periphery of the drive gear 82. The driven gear 83 is connected to the input end of the drive roller 3 shaft.

[0031] The heat insulation cover 6 is equipped with a heat insulation plate inside, so that the heat insulation cover 6 can block the heat in the trolley furnace from being transferred to the motor 7.

[0032] The working principle of the automatic tilting fixture for bogie hearth provided by this utility model is as follows:

[0033] Place the tooling on the trolley of the trolley furnace and ensure that the support seat 1 is stable.

[0034] A spherical or cylindrical workpiece is placed in the area between the drive roller 3 and the follower roller 4. Since the distance between the drive roller 3 and the follower roller 4 is smaller than the diameter of the workpiece, the workpiece will be stably rested on the drive roller 3 and the follower roller 4.

[0035] After the motor 7 starts, its output shaft 81 drives the drive gear 82 to rotate. The drive gear 82 meshes with the driven gear 83, thereby driving the driven gear 83 to rotate. The driven gear 83 is connected to the rotating shaft of the drive roller 3, causing the drive roller 3 to rotate.

[0036] When the drive roller 3 rotates, it drives the workpiece to rotate through friction, achieving automatic flipping. The toothed design of the anti-slip sleeve 9 increases the friction with the workpiece, preventing the workpiece from slipping or shifting.

[0037] While the workpiece is flipped on the support 1, the trolley furnace heats the workpiece. The arc-shaped design of the support 1 allows waste chips to slide into the chip guide groove 2, keeping the tooling clean and preventing waste chips from affecting the heating effect or workpiece quality.

[0038] The heat shield 6 and the internal heat insulation plate block the high temperature heat inside the trolley furnace, protect the motor 7 from the high temperature, ensure the normal operation of the motor 7 and extend its service life.

[0039] After the flipping is complete, motor 7 stops running. After the workpiece has cooled down, it is removed from between the drive roller 3 and the follower roller 4, completing the entire operation.

[0040] 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.
