Description

Technical Field

[0001] This utility model belongs to the field of fixture technology, specifically relating to a combined bearing housing machining fixture. Background Technology

[0002] Bearing housings are important components in machinery and equipment used to support and fix bearings. During the processing and production of bearing housings, they need to be clamped and installed. They are usually clamped by fixtures. Existing fixtures are tooling used for clamping and installing bearing housings. They are reinforced and clamped by combining clamping plate one, clamping plate two and side clamping plate.

[0003] Existing fixtures, when clamping and installing bearing housings during manufacturing, do not easily clamp the sides of the bearing housing after clamping both ends. Therefore, when the bearing housing is subjected to large forces during machining, it is easy to cause lateral displacement of the bearing housing, resulting in machining errors when the bearing housing is not securely fastened, reducing machining accuracy, and affecting the stability of the fixture's end clamping and side clamping during bearing housing manufacturing. To address this, this utility model proposes a combined bearing housing machining fixture. Utility Model Content

[0004] The purpose of this utility model is to provide a combined bearing housing machining fixture to solve the problem mentioned in the background art that after the fixture clamps the end of the bearing housing, it is not convenient to clamp and install the side of the bearing housing. Therefore, when the bearing housing is subjected to large forces during machining, it is easy to cause lateral displacement of the bearing housing, which will cause the bearing housing to be loose and offset, resulting in errors during machining and reducing the accuracy of machining.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined bearing seat processing fixture, comprising a fixture body, the fixture body including a base, a fixing plate welded to one end of the upper surface of the base, a clamping plate fixedly mounted on the inner side of the fixing plate by mounting bolts, and the end of the clamping plate being fixed to the surface of the base by mounting bolts; the fixture body also includes:

[0006] A convenient adjustable clamping mechanism is provided, and the convenient adjustable clamping mechanism includes a top clamping component disposed at the other end of the upper surface of the base, and side clamping components are disposed at both ends of the inner side of the top clamping component, and an adjustment component is disposed at the bottom end of the side clamping component inside the base;

[0007] A tightening and protective mechanism is provided, and the tightening and protective mechanism includes a protective component disposed at the end of the tightening component, and a rotating fixing component is provided at the connection between the protective component and the tightening component.

[0008] Preferably, the clamping assembly includes a second clamping plate that is fixedly mounted on the other end of the upper surface of the base by mounting bolts. The second clamping plate has two threaded clamping posts connected internally by threads, and the ends of the threaded clamping posts are provided with internal hexagonal slots.

[0009] Preferably, the side clamping assembly includes side clamps disposed at both ends of the inner side of the clamping plate two, the side clamps having an adjustment groove inside, a fixing bolt passing through the adjustment groove, and both ends of the inner side of the clamping plate two having a main internal thread hole that rotates with the fixing bolt one.

[0010] Preferably, the two side clamps are symmetrically arranged, and the inner sides of the side clamps and the second clamp are rotatably fixed by the first fixing bolt and the main internal thread hole.

[0011] Preferably, the adjustment component is formed in an adjustment groove inside the base, and a bidirectional lead screw is rotatably mounted inside the adjustment groove. An adjustment nut is welded and fixed to the end of the bidirectional lead screw on the side of the base. Both ends of the bidirectional lead screw are provided with movable seats, and the top of the movable seats is fixed to the bottom of the side clamp by welding.

[0012] Preferably, the protective component includes a hard rubber disc disposed on the end surface of the threaded clamping post, and a connecting post is mounted at the middle position of the end of the threaded clamping post via a bearing.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By designing a conveniently adjustable clamping mechanism, the bearing housing can be positioned on the surface of the base by clamping plate one and clamping plate two. Then, the threaded clamping column can be rotated to tighten it. The two side clamping plates can be moved towards each other again. When the side clamping plates move, they slide on the surface of fixing bolt one by adjusting the transverse groove until the side clamping plates are clamped on the side of the bearing housing. The fixing bolt one is then rotated to insert into the main internal thread hole to fix the side clamping plates in place. This reinforces the bearing housing and makes it more stable under processing force after installation. It is less prone to lateral displacement, allowing for precise processing and improving the stability of the fixture body during the processing and production of the bearing housing by end clamping and side clamping.

Detailed Implementation

[0023] 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.

[0024] Please see Figures 1 to 6 This utility model provides a technical solution: a combined bearing housing processing fixture, including a fixture body 100, a base 101, a fixing plate 102 welded to one end of the upper surface of the base 101, a clamping plate 103 fixedly installed on the inner side of the fixing plate 102 by mounting bolts, and the end of the clamping plate 103 fixed to the surface of the base 101 by mounting bolts. When clamping different types of bearing housings, the clamping plate 103 can be installed through the fixing plate 102 during the processing and clamping of the bearing housing, and the clamping plate 103 and the clamping plate 1011 can be combined for clamping. The clamping plate 103 can be replaced with clamping plates of different thicknesses for limiting clamping. The fixture body 100 is also provided with:

[0025] The convenient adjustable clamping mechanism includes a clamping component located at the other end of the upper surface of the base 101. Side clamping components are provided at both ends of the inner side of the clamping component. An adjustment component is provided at the bottom end of the side clamping component inside the base 101. The clamping body 100 can be clamped to the end of the bearing by the convenient adjustable clamping mechanism when the bearing seat is being processed, and the side clamping reinforcement installation is stabilized and reinforced at the same time.

[0026] In order to facilitate the bearing to be limited and fixed by the clamping assembly, in this embodiment, preferably, the clamping assembly includes a second clamping plate 1011 fixedly installed on the other end of the upper surface of the base 101 by mounting bolts. The second clamping plate 1011 has two threaded clamping posts 1012 connected internally by threads. The ends of the threaded clamping posts 1012 are provided with internal hexagonal slots. After the bearing seat is limited by the first clamping plate 103 and the second clamping plate 1011, the threaded clamping posts 1012 rotate inside the second clamping plate 1011 to clamp and install.

[0027] To facilitate the clamping and installation of the bearing housing on both sides using the side clamping assembly, in this embodiment, preferably, the side clamping assembly includes side clamping plates 1013 disposed at both ends of the inner side of the second clamping plate 1011. The two side clamping plates 1013 are symmetrically arranged. An adjusting transverse groove 1014 is provided inside the side clamping plate 1013. A fixing bolt 1015 passes through the interior of the adjusting transverse groove 1014. Both ends of the inner side of the second clamping plate 1011 are provided with a main internal thread hole that rotates with the fixing bolt 1015. When adjusting the side clamping plate 1013, it can be moved on the surface of the fixing bolt 1015 through the adjusting transverse groove 1014 until the side clamping plate 1013 contacts the surface of the bearing housing and is clamped. The fixing bolt 1015 is then rotated to engage with the main internal thread hole to fix and clamp the side clamping plate 1013.

[0028] To facilitate the simultaneous movement and clamping of the two side clamping plates 1013 via the adjustment assembly, in this embodiment, preferably, the adjustment assembly is formed in an adjustment groove 1017 inside the base 101. A bidirectional lead screw 1018 rotates inside the adjustment groove 1017. An adjustment nut 1019 is welded and fixed to the end of the bidirectional lead screw 1018 on the side of the base 101. Both ends of the bidirectional lead screw 1018 are provided with movable seats 1016, and the top of the movable seats 1016 is welded and fixed to the bottom of the side clamping plates 1013. The fixing bolt 1015 can be loosened, and the bidirectional lead screw 1018 can be rotated by the adjustment nut 1019. When the bidirectional lead screw 1018 rotates, it drives the two movable seats 1016 to move towards each other, thereby driving the two side clamping plates 1013 to move towards each other and clamp through the movable seats 1016.

[0029] The tightening and protective mechanism includes a protective component disposed at the end of the tightening component. A rotating fixing component is disposed at the connection between the protective component and the tightening component. When the rotating threaded tightening column 1012 is tightened, the tightening and protective mechanism protects and tightens the end of the threaded tightening column 1012, making it less likely to cause squeezing damage during tightening.

[0030] In order to facilitate the use of the protective component to keep the end of the threaded clamping post 1012 stationary during rotational clamping and to protect it, in this embodiment, preferably, the protective component includes a hard rubber disc 104 disposed on the end surface of the threaded clamping post 1012. A connecting post 1042 is mounted at the middle position of the end of the threaded clamping post 1012 via a bearing. When the threaded clamping post 1012 rotates, the hard rubber disc 104 can be moved forward and clamped while remaining stationary through the rotation of the connecting post 1042, and the clamping installation is less likely to cause damage to the bearing seat due to compression during clamping installation.

[0031] To facilitate the fixed installation of the rigid rubber disc 104 and the connecting post 1042 via a rotating fixing assembly, in this embodiment, preferably, the rotating fixing assembly includes three fixing bolts 1041 threadedly connected inside the rigid rubber disc 104, with the top ends of the fixing bolts 1041 embedded inside the rigid rubber disc 104. The end of the connecting post 1042 is provided with an auxiliary internal threaded hole 1043 threadedly connected to the fixing bolts 1041. After the rigid rubber disc 104 is closed on the end of the connecting post 1042, the fixing bolts 1041 are rotated to embed into the auxiliary internal threaded hole 1043 to fix the rigid rubber disc 104 in place.

[0032] The working principle and usage process of this utility model: When using this type of combined bearing seat processing fixture, the fixture body 100 is first fixed at the position of use by the base 101. When using, the clamping plate 103 is fixed to one end of the upper surface of the base 101 by the fixing plate 102. The bearing seat is limited and placed by the clamping plate 103 and the clamping plate 1011. After the limited placement, the wrench is engaged in the internal hexagonal groove of the end of the threaded clamping column 1012 and rotates the threaded clamping column 1012 until the end of the threaded clamping column 1012 is pressed into the corresponding hole at the bottom of the bearing seat.

[0033] Once the wrench is engaged on the surface of the adjusting nut 1019, the double-acting screw 1018 is rotated. When the double-acting screw 1018 is rotated, the moving seat 1016 moves towards each other at both ends of the double-acting screw 1018 and is limited to the inside of the adjusting groove 1017. When the moving seat 1016 moves, the side clamping plate 1013 moves until the side clamping plate 1013 is clamped to the side of the bearing seat. The rotating fixing bolt 1015 is inserted into the main internal thread holes at both ends of the inner side of the clamping plate 1011 to fix the side clamping plate 1013 and clamp the side of the bearing seat. This makes it easier to clamp the bearing seat after the fixture body 100 is tightened, and facilitates the side clamping installation. After installation, the machine is more stable under stress and less prone to lateral displacement, allowing for precise machining and improving the stability of the fixture body 100 during bearing seat machining and production by tightening the end and clamping the side.

[0034] Then, before clamping and installing, the rigid rubber disc 104 is closed on the end of the threaded clamping column 1012, and the fixing bolt 1041 is rotated and installed corresponding to the auxiliary internal thread hole 1043, so that the rigid rubber disc 104 is fixed to the end of the connecting column 1042. When clamping and installing the rotating threaded clamping column 1012, the surface of the rigid rubber disc 104 in contact with the bearing seat is kept still so that the threaded clamping column 1012 can be rotated and clamped smoothly. This makes it less likely for friction damage to occur between the end of the threaded clamping column 1012 and the bearing seat during clamping and reinforcement, effectively protecting the clamping installation and improving the convenience of clamping the end of the threaded clamping column 1012 during the clamping of the bearing seat.

[0035] Although embodiments of the present invention have been shown and described (see the detailed description above), 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.
