Description

Technical Field

[0001] This utility model belongs to the technical field of heat treatment auxiliary equipment, specifically relating to a multi-position hanging fixture rotation device for a pit-type heat treatment furnace. According to the planned number of workpieces to be heat treated in a single furnace, the device can rotate the hanging fixture to the required position to load and unload workpieces when loading and unloading workpieces in the multi-position hanging fixture of the pit-type heat treatment furnace. Background Technology

[0002] Currently, in pit-type heat treatment furnace production, hanging fixtures are commonly used. For single-furnace, multi-piece heat treatment processes require multiple hanging fixtures. These fixtures are placed on a high support platform. A lifting device hoists each workpiece to be heat-treated individually to an empty slot on the fixture for suspension. The lifting device then raises the fixture to a certain height, detaching it from the support platform. The lifting hook is manually rotated, causing the fixture to rotate and reposition itself to the appropriate location. The same process is repeated until all fixture slots are occupied as required. Removing the heat-treated workpieces from the hanging fixture also requires repeating these steps.

[0003] This type of pit-type heat treatment furnace uses a multi-position hanging fixture for loading and unloading, which is cumbersome and inefficient. It requires two lifting devices, which need to work in close coordination and are prone to collisions. The related operations require two people to work together, and the labor intensity of the rotating hanging fixture is extremely high, especially when producing large-tonnage workpieces, where multiple people are needed to rotate the fixture. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of existing multi-position hanging tool loading and unloading methods and provide a rotating device for multi-position hanging tooling of pit-type heat treatment furnace that improves loading and unloading efficiency, reduces equipment and personnel waste, reduces labor intensity, and reduces operational risks.

[0005] The purpose of this utility model is achieved through the following measures: a multi-position hanging tooling rotation device for a pit-type heat treatment furnace, including a high platform, a material support platform welded and fixed to the high platform, a base fixed to the high platform by bolts, a transmission box with upper and lower layers fixed to the base by bolts, a reducer fixed to the transmission box by bolts, and a motor that provides power and is directly connected to the reducer.

[0006] The base has upper and lower planes that are parallel to each other, and is used to support the transmission mechanism and the power mechanism.

[0007] An upper bearing and a lower bearing are installed in the lower layer of the transmission housing. A transmission shaft is installed between the upper bearing and the lower bearing. The transmission shaft is positioned in the transmission housing by the upper bearing and the lower bearing. A gear is installed and fixed on the transmission shaft in the lower layer of the transmission housing by a flat key. The transmission shaft in the upper layer of the transmission housing is connected to the output shaft of the reducer by a coupling.

[0008] The material receiving platform and the elevated platform have U-shaped openings of the same specifications for suspending tooling into the suspension. A U-shaped slide is welded and fixed on the material receiving platform. The U-shaped slide is a cylindrical steel part with a U-shaped opening. The U-shaped opening of the slide matches the U-shaped opening of the material receiving platform. The depth and width of the U-shape are the same for both. An annular groove is provided on the U-shaped slide to serve as an annular slide.

[0009] A U-shaped gear is placed on a U-shaped slide. The U-shaped gear is a cylindrical gear with a U-shaped opening machined on it. The depth and width of the U-shaped opening are consistent with those of the U-shaped opening of the U-shaped slide. An annular boss is machined below the U-shaped gear. The inner and outer circles of the boss and the inner and outer circles of the groove of the U-shaped slide form a clearance fit, ensuring that the boss of the U-shaped gear and the groove of the U-shaped slide fit together, realizing the circumferential sliding of the U-shaped gear. The gear meshes with the U-shaped gear, driving the U-shaped gear to rotate. Multiple hanging fixtures are suspended on the U-shaped gear. The U-shaped gear rotates circumferentially on the U-shaped slide, driving the hanging fixtures to rotate, realizing the circumferential displacement of the hanging fixtures.

[0010] The height of the boss of the U-shaped gear is greater than the depth of the groove of the U-shaped slide. The bottom and sides of the groove are ground surfaces with high gloss. A lubrication groove is machined at the bottom of the groove.

[0011] Compared with the prior art, the advantages of this utility model are as follows:

[0012] With a wide range of applications, this device can be used for loading and unloading workpieces during single-furnace, multi-branch hanging production in pit-type heat treatment furnaces.

[0013] The device has a clear structure and is highly operable.

[0014] By reducing the amount of lifting equipment required, the operation can be completed with just one crane.

[0015] By reducing manpower and increasing efficiency, the task can be completed by one person, while reducing unnecessary actions and increasing work efficiency.

[0016] Reduce the labor intensity of personnel. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] like Figure 1 As shown, a multi-position hanging tooling rotation device for a pit-type heat treatment furnace includes a material support platform 1, a U-shaped slide 2, a U-shaped gear 3, a base 4, a transmission box 5, a gear 6, a lower bearing 7, an upper bearing 8, a transmission shaft 9, a coupling 10, a belt reducer 11, and a motor 12.

[0026] Specifically, it is a multi-position hanging tooling rotation device for a pit-type heat treatment furnace, including a high platform 13, a material support platform 1 welded and fixed on the high platform 13, a base 4 fixed on the high platform 13 by bolts, a transmission box 5 with upper and lower layers fixed on the base 4 by bolts, a reducer 11 fixed on the transmission box 5 by bolts, and a motor 12 that provides power and is directly connected to the reducer 11.

[0027] The base 4 has upper and lower planes that are parallel to each other, and is used to support the transmission mechanism and the power mechanism; that is, the base 4 is placed on the high platform 13 and is fixed to the high platform 13 by bolts; the base 4 is made of steel and has upper and lower planes that are parallel to each other, and is used to support the transmission mechanism and the power mechanism of the device.

[0028] An upper bearing 8 and a lower bearing 7 are installed in the lower layer of the transmission housing 5. A transmission shaft 9 is installed between the upper bearing 8 and the lower bearing 7. The transmission shaft 9 is positioned in the transmission housing 5 through the upper bearing 8 and the lower bearing 7. A gear 6 is installed and fixed on the transmission shaft 9 in the lower layer of the transmission housing 5 by a flat key. The transmission shaft 9 in the upper layer of the transmission housing 5 is connected to the output shaft of the reducer 11 through a coupling 10.

[0029] like Figure 1 , 2As shown in Figure 3, the material support platform 1 is fixed on the high platform 13. The material support platform 1 is welded to the high platform 13. The material support platform 1 and the high platform 13 have U-shaped openings of the same specifications for hanging tooling into the suspension.

[0030] like Figure 1 , 4 As shown in Figure 5, the material receiving platform 1 and the elevated platform 13 have U-shaped openings of the same specifications for suspending tooling. A U-shaped slide 2 is welded and fixed to the material receiving platform 1. The U-shaped slide 2 is a cylindrical steel part with a U-shaped opening. The U-shaped opening of the U-shaped slide 2 is consistent with the U-shaped opening of the material receiving platform 1, and the depth and width of the U-shape are the same. An annular groove is formed on the U-shaped slide 2 as an annular slide. The bottom and sides of the groove are ground to form a high-gloss surface, and a lubrication groove is machined at the bottom to effectively reduce the coefficient of friction.

[0031] like Figure 1 , 6 As shown in Figure 7, a U-shaped gear 3 is placed on the U-shaped slide 2. The U-shaped gear 3 is a cylindrical gear with a U-shaped opening machined on it. The depth and width of the U-shaped opening are consistent with those of the U-shaped opening of the U-shaped slide 2. An annular boss is machined below the U-shaped gear 3. The inner and outer circles of the boss are similar in size to the inner and outer circles of the groove of the U-shaped slide 2, ensuring that the inner and outer circles of the boss and the groove of the U-shaped slide 2 form a clearance fit. This allows the boss of the U-shaped gear 3 to engage with the groove of the U-shaped slide 2, enabling the U-shaped gear 3 to slide circumferentially. The surface of the boss is ground to achieve a high surface finish. Gear 6 meshes with the U-shaped gear 3, driving the U-shaped gear 3 to rotate. Multiple hanging fixtures are suspended on the U-shaped gear 3. The U-shaped gear 3 rotates circumferentially on the U-shaped slide 2, driving the hanging fixtures to rotate, thus achieving circumferential displacement of the hanging fixtures.

[0032] The height of the boss of the U-shaped gear 3 is greater than the depth of the groove of the U-shaped slide 2. The bottom and sides of the groove are ground surfaces with high gloss. A lubrication groove is machined at the bottom of the groove.

[0033] The belt reducer 11 is placed on the transmission housing 5 and fixed by bolts; the transmission shaft 9 installed on the transmission housing 5 is connected to the output shaft of the reducer 11 through the coupling 10; the motor 12 is directly connected to the reducer 11, and the motor 12 provides power to reduce the speed and increase the output torque through the belt reducer 11; the reducer 11 is connected to the transmission shaft 9 through the coupling 10, driving the transmission shaft 9 to rotate; the rotation of the transmission shaft 9 drives the gear 6 to rotate; the gear 6 meshes with the U-shaped gear 3, driving the U-shaped gear 3 to rotate; the hanging fixture is suspended on the U-shaped gear 3, and the rotation of the U-shaped gear 3 drives the hanging fixture to rotate.

[0034] This invention provides kinetic energy to the device through a motor 12. The motor is directly connected to a belt reducer 11, which reduces the output speed and increases the output torque through a reducer 11. The reducer 11 is connected to a transmission shaft 9 through a coupling 10, which drives the transmission shaft 9 to rotate. The transmission shaft 9 is connected to a gear 6, which drives the gear 6 to rotate. The gear 6 meshes with a U-shaped gear 3, which drives the U-shaped gear 3 to rotate. The U-shaped gear 3 rotates in a circle on a U-shaped slide. Multiple hanging fixtures are suspended on the U-shaped gear 3. The U-shaped gear 3 drives the multiple hanging fixtures to move in a circle, realizing the circumferential displacement of the hanging fixtures.
