In this way, the position accuracy of the mounting member can be guaranteed. The first penetration hole can provide a mounting position for the first connecting member. After the first connecting member is penetrated through the first penetration hole, the two ends can be connected to the bearing member and the mounting member respectively, so that the mounting member is fixed on the bearing member.

[0017] In some embodiments, the local heating tool further comprises a limiting component which is detachably connected to the bearing component and at least partially located on a side of the bearing component close to the heating element.

[0018] According to the above technical means, in the process of actual application, the staff can design the position of the limit assembly and the position of the limit assembly according to the external shape of the reducer housing. For example, the limit assembly can be designed according to the size and position of the hole on the reducer housing, so that the limit assembly can be inserted into the hole on the reducer housing, so that the reducer housing can be stably set on the support surface.

[0019] In some embodiments, the limiting assembly includes a plurality of limiting members, which are all detachably connected to the bearing assembly and at least partially located on a side of the bearing assembly close to the heating element.

[0020] According to the above technical means, a plurality of limiting members can limit the reducer housing at different positions, thereby ensuring the stability of the reducer housing setting.

[0021] In some embodiments, a plurality of second limiting grooves are formed on the support surface, and a plurality of limiting members are inserted into the plurality of second limiting grooves.

At the same time, the second limit slots facilitate the staff to confirm the setting position of the limit member on the support member.

[0023] In some embodiments, a second through hole is formed at the bottom of the second limiting groove. The limiting assembly further comprises a plurality of second connecting members. The plurality of second connecting members are penetrated through the plurality of second through holes and are detachably connected to the limiting member and the bearing assembly.

[0024] According to the above technical means, the second connecting member can limit the separation of the limiting member and the bearing assembly, thereby ensuring that the limiting member can stably limit the position of the reducer housing.

[0025] In some embodiments, a connection portion is formed at one end of the support member away from the bearing assembly, and the heating member is inserted into the connection portion and is spaced apart from the support surface.

[0026] According to the above technical means, the plug-in portion can provide an installation position for the heating element and fix the installation element so that the installation element can stably heat the reducer housing.

[0027] Therefore, the above technical features of the present application have the following beneficial effects:

[0028] (1) In actual application, the reducer housing can be placed on the support surface. Since one end of the support member is detachably connected to the bearing assembly, the staff can remove the support member from the bearing assembly in actual application.

[0032] (5) The inner wall of the first limiting groove can abut against the mounting member, thereby limiting the mounting member. In this way, the position accuracy of the mounting member can be guaranteed. The first through hole can provide a mounting position for the first connecting member.

DETAILED DESCRIPTION

[0045] In order to enable ordinary persons in the art to better understand the technical solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0046] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0047] The existing local heating tooling generally includes a bottom support, a bracket, a heating element and a positioning element. The positioning element is arranged on the surface of the bottom support and is used to position the reducer housing. One end of the bracket is connected to the bottom support, and the other end forms a gap with the bottom support. The heating element is connected to the other end of the bracket. The bracket can fix the position of the heating element so that the heating element and the bottom support are kept at a relatively fixed position and angle.

[0048] When it is necessary to heat the reducer case locally, the staff will place the reducer case on the surface of the bottom support, and the positioning piece can ensure that the reducer cases of the same specifications are accurately placed at the same position on the surface of the bottom support. In this way, after the heating element is started, the same position of the reducer cases of the same specifications can be evenly heated.

[0049] In the existing local heating tool, when the reducer housing is installed on the bottom support, the space between the bottom support and the heating element is limited, and the heating element may interfere with the side wall of the reducer housing. At the same time, the bracket and the positioning member will also have a certain impact on the installation and removal of the reducer housing.

[0050] Based on this, the embodiment of the present application provides a local heating tool, such as Figure 1 As shown, Figure 1 This is one of the structural schematic diagrams of the local heating tool 100 provided in the embodiment of the present application. The local heating tool 100 may include a bearing assembly 1, a support member 2, and a heating member 3. The bearing assembly 1 may have a support surface 11. In actual application, the reducer housing may be placed on the support surface 11.

[0051] One end of the support member 2 is detachably connected to the bearing assembly 1. In actual application, the staff can remove the support member 2 from the bearing assembly 1. In this way, when the staff sets the reducer housing on the support surface 11 or removes the reducer housing from the support surface 11, the support member 2 will not interfere with the reducer housing, and the staff can easily set the reducer housing on the support surface 11 or remove the reducer housing from the support surface 11.

[0052] The other end of the support member 2 is located on the side where the support surface 11 is located, and extends in a direction away from the load-bearing component 1. The heating element 3 is connected to the end of the support member 2 away from the load-bearing component 1, and is spaced apart from the support member 2. In this way, the support member 2 can provide an installation position for the heating element 3, so that a gap is formed between the heating element 3 and the support surface 11. In the actual application process, the staff can place the part of the reducer housing that needs to be heated in the gap between the heating element 3 and the support surface 11, and the heating element 3 can locally heat the part of the reducer housing that needs to be heated.

[0053] Since one end of the support member 2 is detachably connected to the bearing assembly 1, in the actual application process, when the reducer housing needs to be set on the bearing assembly 1, the staff can first remove the support member 2 from the bearing assembly 1. In this way, when the reducer housing is set on the bearing assembly 1, the reducer housing will not interfere with the support member 2. After the reducer housing is set on the bearing assembly 1, the staff can reconnect the support member 2 with the bearing assembly 1, and the support member 2 can support the heating member 3 in a fixed position, and the heating member 3 can stably heat the reducer housing.

[0054] In some embodiments, Figure 1 As shown, a connection portion 26 is formed at one end of the support member 2 away from the bearing assembly 1, and the heating member 3 is inserted into the connection portion 26 and is spaced apart from the support surface 11. In this way, the connection portion 26 can provide an installation position for the heating member 3 and fix the heating member 3 so that the heating member 3 can stably heat the reducer housing.

[0055] For example, Figure 1 As shown, the connection portion 26 can be a plug-in slot, and the heating element 3 can be a hot air gun, which is plugged into the plug-in slot, and the air outlet of the hot air gun faces the support surface 11. The plug-in slot can fix the height position and setting angle of the hot air gun, thereby ensuring that the heating element 3 stably heats the reducer housing.

[0056] Continue to refer to Figure 1 The connecting portion 26 may be a rectangular groove, and the four inner walls of the rectangular groove are in contact with the outer wall of the heat gun. In this way, the rectangular groove can set the heat gun at a fixed angle. The handle of the heat gun is in contact with the side of the support member 2 away from the bearing assembly 1, so that the support member 2 keeps the heat gun at a suitable height.

[0057] It should be noted that the connection portion 26 may also be a plug-in slot of other shapes, as long as it is ensured that the hot air gun can be stably maintained at a certain angle when plugged into the connection portion 26 .

[0058] In order to realize the detachable connection between the support member 2 and the bearing assembly 1, in some embodiments, as Figure 2 As shown, Figure 2 The second structural diagram of the local heating tool 100 provided in the embodiment of the present application, the bearing component 1 is provided with a plug-in slot 12, and one end of the support member 2 connected to the bearing component 1 is plugged into the plug-in slot 12. In this way, the support member 2 can be connected to the bearing component 1 by plugging, and in the actual application process, the staff can connect or separate the support member 2 and the bearing component 1 by plugging and unplugging, which is convenient for the staff to connect or separate the support member 2 and the bearing component 1.

[0059] It is understandable that the support member 2 can also be detachably connected to the bearing assembly 1 in other ways. For example, a clamping groove (not shown in the figure) can be formed at one end of the support member 2 connected to the bearing assembly 1, and a clamping portion (not shown in the figure) is formed on the bearing assembly 1, and the clamping portion is clamped in the clamping groove. In this way, the support member 2 and the bearing assembly 1 can also be detachably connected.

[0060] Alternatively, the support member 2 may also be fixed to the bearing assembly 1 by bolts. In this case, the support member 2 can be separated from the bearing assembly 1 by simply removing the bolts.

[0061] In order to improve the stability of the connection between the support member 2 and the bearing assembly 1, in some embodiments, such as Figure 2 As shown, there are multiple plug-in slots 12, which are arranged at intervals, and one end of the support member 2 connected to the bearing assembly 1 is formed with multiple plug-in portions 21, which are plugged into the multiple plug-in slots 12. In this way, the multiple plug-in slots 12 can fix the plug-in portions 21 of the support member 2 at different positions, so that the support member 2 can be limited from different positions to ensure that the support member 2 can be stably arranged on the bearing assembly 1.

[0062] In some embodiments, Figure 3 As shown, Figure 3 The structural diagram of the bearing assembly 1 and the limiting assembly 4 provided in the embodiment of the present application is shown in FIG. The bearing assembly 1 may include a bearing member 13, a mounting member 14 and a first connecting member 15. The bearing member 13 has a supporting surface 11. The bearing member 13 may be used to support the reducer housing.

[0063] The mounting member 14 is located on the side where the support surface 11 is located, and the side of the mounting member 14 away from the support surface 11 is provided with the plug slot 12. In this way, in the process of actual application, the mounting member 14 can provide a setting position for the plug slot 12.

[0064] The first connecting member 15 is detachably connected to the mounting member 14 and the bearing member 13. In this way, in actual application, when the mounting member 14 is damaged, the staff can remove the first connecting member 15, so that the mounting member 14 and the bearing member 13 can be separated from each other, and the staff can easily replace the mounting member 14.

[0065] For example, Figure 2 As shown, the inner wall of the plug slot 12 needs to abut against the plug portion 21 to ensure the stability of the support member 2. In actual application, the inner wall of the plug slot 12 will deform after a long period of force, which will affect the positioning accuracy of the plug slot 12 to the support member 2. The staff can Figure 3 ) is separated from the mounting member 14 and the supporting member 13, and the mounting member 14 is replaced.

[0066] In some embodiments, Figure 3 As shown, a first limiting groove 111 is formed on the support surface 11, and the mounting member 14 is inserted into the first limiting groove 111. In this way, the inner wall of the first limiting groove 111 can abut against the mounting member 14, thereby limiting the mounting member 14. In this way, the position accuracy of the mounting member 14 can be guaranteed.

[0067] A first through hole 112 is formed at the bottom of the first limiting groove 111, and the first connecting member 15 is inserted through the first through hole 112 and is detachably connected to the bearing member 13 and the mounting member 14. The first through hole 112 can provide a mounting position for the first connecting member 15. After the first connecting member 15 is inserted through the first through hole 112, two ends of the first connecting member 15 can be connected to the bearing member 13 and the mounting member 14 respectively, so that the mounting member 14 is fixed to the bearing member 13.

[0068] Exemplarily, the first connecting member 15 may be a connecting bolt, a thread groove may be provided at the bottom of the mounting member 14, and the threaded end of the first connecting member 15 is passed through the first penetration hole 112 and is threadedly connected to the thread groove at the bottom of the mounting member 14. In this way, the first connecting member 15 can be detachably connected to the mounting member 14 and the bearing member 13.

[0069] In other embodiments, the mounting member 14 can also be detachably connected to the carrier 13 in other ways. For example, a protrusion can be formed on the surface of the carrier 13, and a groove can be formed on the bottom of the mounting member 14, and the protrusion can be snapped into the groove. In this way, the mounting member 14 can also be detachably connected to the carrier 13.

[0070] In order to fix the position of the reducer housing, in some embodiments, as Figure 2As shown, the local heating tool 100 further includes a limiting component 4. The limiting component 4 is detachably connected to the bearing component 1, and at least part of it is located on the side of the bearing component 1 close to the heating element 3. In this way, the part of the limiting component 4 located on the side of the bearing component 1 close to the heating element 3 can limit the position of the reducer housing, thereby fixing the reducer housing on the bearing component 1.

[0071] In the actual application process, the staff can design the position of the limit assembly 4 and the position of the limit assembly 4 according to the external shape of the reducer housing. For example, the limit assembly 4 can be designed according to the size and position of the hole on the reducer housing, so that the limit assembly 4 can be inserted into the hole on the reducer housing, so that the reducer housing is stably set on the support surface 11.

[0072] Alternatively, the limiting assembly 4 can also be arranged according to the external shape of the reducer housing, and when the reducer housing is placed on the support surface 11, the limiting assembly 4 can abut against the outer side of the reducer housing in different orientations. In this way, the limiting assembly 4 can also limit the position of the reducer housing.

[0073] In some embodiments, Figure 3 As shown, the limiting assembly 4 may include a plurality of limiting members 41. The plurality of limiting members 41 may limit the reducer housing at different positions, thereby ensuring the stability of the reducer housing.

[0074] For example, Figure 3 As shown, the number of the limiting members 41 may be four, and the four limiting members 41 may be respectively inserted into different hole structures of the reducer housing to locate the position of the reducer housing on the bearing member 13 .

[0075] The plurality of stoppers 41 are detachably connected to the bearing assembly 1, and at least part of them are located on one side of the bearing assembly 1 close to the heating element 3. In this way, in the actual application process, when the stopper 41 is damaged, the staff can easily replace the damaged stopper 41.

[0076] In some embodiments, Figure 3 As shown, a plurality of second limiting grooves 113 are formed on the support surface 11, and a plurality of limiting members 41 are inserted into the plurality of second limiting grooves 113. In this way, a detachable connection between the limiting member 41 and the bearing assembly 1 can be achieved. At the same time, the second limiting grooves 113 facilitate the staff to confirm the setting position of the limiting member 41 on the bearing member 13.

[0077] In some embodiments, a second through hole 114 is formed at the bottom of the second limiting groove 113. The limiting assembly 4 further includes a plurality of second connecting members 42, which are penetrated through the plurality of second through holes 114 and are detachably connected to the limiting member 41 and the bearing assembly 1.

[0078] In this way, the second connecting member 42 can limit the separation of the limiting member 41 from the bearing assembly 1, thereby ensuring that the limiting member 41 can stably limit the position of the reducer housing.

[0079] For example, Figure 3 As shown, the second connecting member 42 can be a connecting bolt, and a threaded hole is provided at the bottom of the limiting member 41. The threaded end of the connecting bolt can be threadedly connected with the threaded hole at the bottom of the limiting member 41 after passing through the second penetration hole 114.

[0080] Alternatively, the second connecting member 42 may also be an elastic clamping member, a clamping hole is provided at the bottom of the limiting member 41, and the clamping joint of the second connecting member 42 passes through the second through hole 114 and is clamped in the clamping hole at the bottom of the limiting member 41, and the other end of the second connecting member 42 abuts against the side of the bearing member 13 away from the supporting surface 11. In this way, the second connecting member 42 can also be detachably connected to the limiting member 41 and the bearing assembly 1, respectively.

[0081] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto, and any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
