Description

Technical Field

[0001] This utility model relates to a heating device, and more particularly to a heating device for bearing housing production. Background Technology

[0002] The heating device used in bearing housing production is a specialized piece of equipment for achieving interference fit assembly between the bearing housing and the shaft or bearing. It ensures precise installation through the principle of thermal expansion.

[0003] For example, a bearing oil bath heating device disclosed in Chinese Patent Publication No. CN219818682U includes a heating box. The top port of the heating box is equipped with a cover that can be moved up and down via a lifting component. A snap-fit ​​sleeve is provided on the lower surface of the cover. The bottom end of the snap-fit ​​sleeve is rotatably snapped with an installation rod. Multiple layers of six-bar forks are provided on the installation rod at intervals. Each end of the six-bar forks is provided with a stabilizing column. A cross is rotatably provided on each stabilizing column. Each end of the cross is provided with a fixing block. A connecting rod passes through each fixing block. A clamping head is provided at the end of the connecting rod near the stabilizing column. A compression spring is provided on the rod body of the connecting rod between the clamping head and the corresponding fixing block. This device is used to solve the problem that when heating a bearing, it is inconvenient to stabilize the bearing, causing the bearing to easily fall from the load-bearing plate into the oil bath during the heating process.

[0004] The existing oil bath heating device has some problems. First, although it can immerse multiple devices in the oil for heating at the same time, they need to be removed at the same time. After removal, the heat source is lost and the heat of the device will be lost quickly, which makes it difficult to quickly install the bearing after completion within an effective time. Utility Model Content

[0005] The purpose of this invention is to provide a heating device for bearing housing production, so as to solve the existing problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heating device for bearing housing production, comprising a heating tank and a bearing housing, wherein a plurality of heating tubes are fixedly connected to the heating tank near the bottom, a crossbeam is fixedly connected to the top of the heating tank, a plurality of high-temperature resistant hydraulic cylinders are fixedly connected to the bottom of the crossbeam, a hanger is fixedly connected to the lower end of the high-temperature resistant hydraulic cylinders, a bracket is fixedly connected to the other end of the hanger, a plurality of mounting slots are provided on the bracket, a placement module is installed in the mounting slot, a placement slot is provided on the placement module, and the bearing housing is placed in the placement slot.

[0007] Preferably, a limiting flange is fixedly connected to the inner wall of the heating tank and above the heating pipe, and a control panel is fixedly connected to the front of the heating tank.

[0008] Preferably, the bracket has oil drain holes located near the four corner edges.

[0009] Preferably, the mounting groove has a slot, and the slot has a fixing threaded hole near the four corner edges.

[0010] Preferably, the outer wall of the placement module is fixedly connected with a protruding edge, and a fixing through hole is opened near the four corner edges of the protruding edge. A fixing bolt is installed in the fixing through hole, and the fixing bolt is threadedly engaged with the fixing threaded hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By using multiple sets of brackets in conjunction with high-temperature hydraulic cylinders, after the bearing housing is heated to a suitable temperature inside the oil, a single high-temperature hydraulic cylinder is activated to move the bracket connected to it upward. The upward movement of the bracket will move a portion of the bearing housing upward, while the remaining bearing housing remains submerged in the heated oil. This avoids removing too many bearing housings at once, which could lead to insufficient processing and excessive temperature drop in subsequent processes.

[0013] 2. The fixing bolts can be unscrewed to release the fixing of the placement module. At this time, the placement module can be removed and replaced. By replacing the placement module, the limiting and positioning of different types of bearing seats can be achieved, so that the device can adapt to the heating of different types of bearing seats.

[0018] 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.

[0019] Please see Figure 1-3 This utility model provides a technical solution: a heating device for bearing housing production, including a heating tank 1 and a bearing housing 5. Several heating tubes 102 are fixedly connected to the heating tank 1 near the bottom. A crossbeam 2 is fixedly connected to the top of the heating tank 1. Several high-temperature resistant hydraulic cylinders 305 are fixedly connected to the bottom of the crossbeam 2. A hanger 304 is fixedly connected to the lower end of the high-temperature resistant hydraulic cylinder 305. A bracket 3 is fixedly connected to the other end of the hanger 304. Several mounting slots 301 are opened on the bracket 3. A placement module 4 is installed in the mounting slot 301. A placement slot 404 is opened on the placement module 4. The bearing housing 5 is placed in the placement slot 404.

[0020] In this embodiment, by adding a certain amount of heating oil into the heating tank 1 and activating the heating pipe 102, the heating oil can be heated to a suitable temperature. The bearing seat 5 to be heated is placed in the placement slot 404. The high-temperature hydraulic cylinder 305 is activated, which drives the bracket 3 to move downward through the hanger 304. The downward movement of the bracket 3 will drive the placement module 4 to move downward, thereby moving the bearing seat 5 downward and immersing it in the heating oil, so that the bearing seat 5 is evenly heated to a suitable temperature. Subsequently, a separate high-temperature hydraulic cylinder 305 is activated to drive the bracket 3 connected to it to move upward. The upward movement of the bracket 3 will drive a portion of the bearing seat 5 upward, while the remaining bearing seat 5 remains submerged in the heating oil. This avoids the problem of the remaining bearing seat 5 cooling down when installing the bearing, which would prevent the bearing from being installed smoothly. The bearing seat 5 is installed in the placement slot 404, which can limit the bearing seat 5 to a certain extent, preventing the bearing seat 5 from shifting, sliding, or even falling off due to vibration during descent or ascent. For heating different models of bearing seats 5 later, the placement module 4 can be replaced to achieve the limiting and positioning of different models of bearing seats 5.

[0021] In order to control the start and stop of the high-temperature hydraulic cylinder 305 or the heating tube 102, the device adopts the following technical solution: a limiting flange 101 is fixedly connected to the inner wall of the heating tank 1 and above the heating tube 102; a control panel 103 is fixedly connected to the front of the heating tank 1; and an oil drain hole 303 is opened in the bracket 3 near the four corner edges.

[0022] The limiting flange 101 can limit the downward stroke of the bracket 3, so as to prevent the bracket 3 from hitting the heating tube 102 when the high-temperature hydraulic cylinder 305 fails, which would damage the internal heating components and cause greater losses. The control panel 103 can realize simple human-machine interaction and is used to control the start and stop of the high-temperature hydraulic cylinder 305 or the heating tube 102. The oil drain hole 303 is used for the inlet and outlet of oil.

[0023] In order to achieve the purpose of fixing the module 4, the device adopts the following technical solution: a slot is provided in the mounting groove 301, and a fixing threaded hole 302 is provided in the slot near the four corner edges. A protrusion is fixed to the outer wall of the module 4, and a fixing through hole 401 is provided in the protrusion near the four corner edges. A fixing bolt 403 is provided in the fixing through hole 401, and the fixing bolt 403 is threadedly engaged with the fixing threaded hole 302.

[0024] By engaging the protruding edge and the retaining edge, the placement module 4 can be secured inside the mounting slot 301. Then, the fixing bolt 403 is screwed into the fixing threaded hole 302 through the fixing through hole 401, thus fixing the placement module 4 inside the mounting slot 301.

[0025] The working principle and usage process of this utility model are as follows: Place the bearing seat 5 to be heated in the placement slot 404, start the heating tube 102 to heat the heating oil to a suitable temperature, start the high temperature resistant hydraulic cylinder 305 to drive the bracket 3 to move down through the hanger 304, the bracket 3 will move down and drive the placement module 4 to move down, and then drive the bearing seat 5 to move down and immerse it in the heating oil, so that the bearing seat 5 is evenly heated to a suitable temperature. Then, start a separate high temperature resistant hydraulic cylinder 305 to drive the bracket 3 connected to it to move up. The upward movement of the bracket 3 will drive a part of the bearing seat 5 to move up, while the remaining bearing seat 5 continues to be immersed in the heating oil. After the bearing seat 5 on the single bracket 3 is removed for subsequent processing, the bracket 3 is then controlled to move up again to remove the heated bearing seat 5.

[0026] 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.
