Description

Technical Field

[0001] This utility model relates to the field of bearing housing processing technology, specifically a heat treatment device for roller box bearing housing. Background Technology

[0002] Bearing housings are components in machinery and equipment used to support and fix bearings. They provide stable support for the bearings, enabling them to work normally. They support the bearings, allowing them to bear the axial and radial loads of the machinery and support the rotating shaft. Through a sealing structure, they ensure the cleanliness and lubrication of the internal lubricating oil of the bearing and prevent leakage. The flange and groove portions on the bearing housing reduce the transmission of vibration, thereby reducing machine noise.

[0003] The bearing housing is designed primarily for applications where the load acts vertically on the support surface. In this case, the load that the bearing housing can withstand depends entirely on the bearing's load-bearing capacity. The load that the bearing housing needs to withstand can be increased by increasing the overall strength of the bearing housing through heat treatment.

[0004] Existing heat treatment equipment cannot fix bearing housings of different inner diameters during use, which makes the bearing housings prone to falling off during heat treatment and greatly limits the use of the overall heat treatment equipment. In addition, it cannot cool down the bearing housings quickly. Therefore, a heat treatment device for roller box bearing housings is needed to solve the existing shortcomings. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1 - Figure 4As shown, this utility model provides a technical solution: a heat treatment device for roller bearing seats, including a base 1, a support plate 2 fixedly connected to the top of the base 1, a lifting motor 3 fixedly installed on the top of the support plate 2, a screw 4 fixedly connected to the output shaft of the lifting motor 3, the bottom end of the screw 4 rotatably connected to the inside of the support plate 2, a movable plate 5 threadedly connected to the surface of the screw 4, guide rails 6 fixedly connected to both ends of the outer side of the support plate 2, the guide rails 6 slidably connected to one end of the movable plate 5, an mounting plate 7 fixedly connected to one end of the movable plate 5, a positioning component 8 provided on the bottom side of the mounting plate 7, a fixing rod 9 fixedly connected to the outer side of the support plate 2, a heating wire 10 fixedly connected to one end of the fixing rod 9, a water storage tank 11 fixedly connected to the top of the base 1, and a spraying component 12 provided on the outer side of the water storage tank 11;

[0026] The bearing housing is placed at the bottom of the mounting plate 7, and the inner ring of the bearing housing is fitted onto the outside of the positioning component 8. The bearing housing is fixed by the positioning component 8. After the bearing housing is fixed, the lifting motor 3 is started to drive the screw 4 to rotate, which will drive the movable plate 5 and the mounting plate 7 to move down, thereby driving the positioning component 8 and the bearing housing to move down. After moving down to the appropriate position, the bearing housing is heat-treated by the heating wire 10. During the heat treatment process, the bearing housing is cooled by the spray component 12.

[0027] like Figure 1 - Figure 4 As shown, the positioning assembly 8 includes a fixed plate 801, limiting grooves 802, movable rods 803, an arc-shaped plate 804, a connecting rod 805, a drive motor 806, a rotating plate 807, and a sliding groove 808. The top of the fixed plate 801 is rotatably connected to the bottom of the mounting plate 7. There are four limiting grooves 802, which are formed around the outer perimeter of the fixed plate 801. There are four movable rods 803, which are respectively disposed inside the four limiting grooves 802. The arc-shaped plate 806... The outer side of 4 is fixedly connected to one end of the movable rod 803, one end of the connecting rod 805 is fixedly connected to the outer side of the movable rod 803, the bottom end of the drive motor 806 is fixedly connected to the top end of the mounting plate 7, the output shaft of the drive motor 806 passes through the mounting plate 7 and the fixed plate 801, the outer side of the rotating plate 807 is fixedly connected to the output shaft of the drive motor 806, there are four slide grooves 808, the slide grooves 808 are opened inside the rotating plate 807, and the connecting rod 805 is located inside the slide grooves 808;

[0028] The positioning component 8 can fix the bearing seat. By starting the drive motor 806, the rotating disk 807 is rotated, causing the connecting rod 805 to slide in the slide groove 808, which in turn causes the movable rod 803 to move outward. At the same time, all four movable rods 803 can be moved outward, so that the arc plate 804 abuts against the inner wall of the bearing seat, which can fix bearing seats with different inner diameters.

[0029] like Figure 1 , Figure 2 and Figure 4 As shown, the spray assembly 12 includes a water pump 1201, a guide pipe 1202, a spray pipe 1203, a connecting pipe 1204, and a nozzle 1205. The bottom end of the water pump 1201 is fixedly connected to the top end of the base 1. The input end of the water pump 1201 is located inside the water storage tank 11. The bottom end of the guide pipe 1202 is fixedly connected to the output end of the water pump 1201. The guide pipe 1202 is made of a flexible hose. The outer side of the spray pipe 1203 is fixedly connected to the top end of the guide pipe 1202. Several connecting pipes 1204 are fixedly connected to the bottom side of the spray pipe 1203. The top end of the nozzle 1205 is fixedly connected to the bottom end of the connecting pipe 1204.

[0030] The spray assembly 12 can be used to spray and cool the bearing housing after heat treatment. The bearing housing is heat treated by the heating wire 10. During the heat treatment process, the water pump 1201 is started to draw the cooling water in the water storage tank 11 into the guide pipe 1202, and then delivers it to the spray pipe 1203. It is then sprayed out through the connecting pipe 1204 and the nozzle 1205 to cool the bearing housing after heat treatment. After the cooling is completed, the water will re-enter the interior of the water storage tank 11 to reduce the waste of water resources.

[0031] Working principle: When in use, place the bearing housing at the bottom of the mounting plate 7 and fit the inner ring of the bearing housing onto the outside of the positioning component 8. Start the drive motor 806 to rotate the rotating disk 807, causing the connecting rod 805 to slide in the slide groove 808, which in turn moves the movable rod 803 outward. All four movable rods 803 can be moved outward at the same time, eventually causing the arc plate 804 to abut against the inner wall of the bearing housing, thus fixing the bearing housing. This method can fix bearing housings with different inner diameters.

[0032] After the bearing housing is fixed, the screw 4 is rotated by starting the lifting motor 3, which in turn moves the movable plate 5 and the mounting plate 7 downward, thereby moving the positioning component 8 and the bearing housing downward. After moving to the appropriate position, the bearing housing is heat-treated by the heating wire 10. During the heat treatment process, the cooling water in the water storage tank 11 is drawn into the guide pipe 1202 by starting the water pump 1201, and then transported to the spray pipe 1203. It is then sprayed out through the connecting pipe 1204 and the nozzle 1205 to cool the heat-treated bearing housing. After the cooling is completed, the water will re-enter the interior of the water storage tank 11 to reduce water waste.

[0033] It should be understood that numerous specific implementation decisions can be made during the development of any actual implementation method, and in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
