Description

Technical Field

[0001] This utility model belongs to the field of casting processing technology, specifically relating to a device for removing the gating system of a bearing housing. Background Technology

[0002] Large bearing housings are typically first cast, then machined using CNC machine tools. After casting, risers and gating gates remain at the ends of the bearing housing. These gates need to be removed before CNC machining. Currently, most methods for removing risers and gating gates involve using hand-held cutting tools to cut and grind them off. However, this manual removal method is dangerous, posing a risk to operators. Furthermore, the uneven surface after removing the risers and gating gates can damage the cutting tools during subsequent CNC machining, hindering rapid feed and impacting the overall machining efficiency of the bearing housing. Utility Model Content

[0003] This utility model provides a bearing housing gating and riser removal device, which aims to solve the problems of high operational risk and poor surface quality of castings when removing gating and risers from cast bearing housings in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a bearing housing gating and riser removal device, comprising:

[0005] Control panel;

[0006] A fixed base, installed on the operating table, is used to place the bearing housing;

[0007] A positioning component, mounted on the fixed base, is used to position the bearing seat on the fixed base;

[0008] A fixing component, disposed on the fixing base, is used to fix the bearing housing to the fixing base;

[0009] A lifting frame is installed on the operating table and has a vertically adjustable position on the operating table. A saw blade for cutting risers and gating gates is installed on the lifting frame.

[0010] In one possible implementation, the positioning component includes:

[0011] The retaining wall is fixedly installed on the fixing base, and the top surface of the fixing base is perpendicular to the retaining wall.

[0012] There are multiple positioning rods, all of which are fixedly installed on the retaining wall, and the multiple positioning rods form a limiting space to prevent the bearing seat from rolling on the operating table.

[0013] In one possible implementation, the fixing component includes:

[0014] There are two hooks, both of which are mounted on the fixed base. The hooks on the fixed base have the freedom to move in a direction perpendicular to the retaining wall.

[0015] A push-pull component, mounted on the fixed base, is used to pull the hook to move on the fixed base.

[0016] In one possible implementation, a connecting plate is fixedly mounted on the drive end of the push-pull member, a pull rod is fixedly mounted on the hook, the pull rod passes through the connecting plate, and a fastener for fixing to the connecting plate is threaded onto the pull rod.

[0017] In one possible implementation, the fixed end of the push-pull member has a degree of freedom to be adjusted along the pitch angle on the fixed base, and a guide component for guiding the push-pull member to flip up and down is also provided between the fixed base and the pull rod.

[0029] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] Please refer to the following: Figures 1 to 3The present invention provides a bearing housing gating and riser removal device. The bearing housing gating and riser removal device includes an operating platform 1, a fixed base 2, a positioning component 3, a fixing component 4, and a lifting frame 5. The fixed base 2 is mounted on the operating platform 1 and is used to place the bearing housing; the positioning component 3 is mounted on the fixed base 2 and is used to position the bearing housing on the fixed base 2; the fixing component 4 is mounted on the fixed base 2 and is used to fix the bearing housing to the fixed base 2; the lifting frame 5 is mounted on the operating platform 1 and has a degree of freedom in vertical adjustment on the operating platform 1, and a saw blade 6 for cutting the gating and riser is mounted on the lifting frame 5.

[0031] The bearing housing riser removal device provided in this embodiment, compared with the prior art, features an operating platform 1, on which a fixed base 2 is installed. The fixed base 2 is equipped with a positioning component 3 for positioning the bearing housing and a fixing component 4 for fixing the bearing housing to the fixed base 2. A lifting frame 5 is also installed above the fixed base 2, and a saw blade 6 is mounted on the lifting frame 5. In use, the bearing housing is installed on the fixed base 2, positioned by the positioning component 3, and then fixed to the fixed base 2 by the fixing component 4. As the lifting frame 5 moves downward, the saw blade 6 moves to the connection point between the bearing housing and the riser. With the lifting frame 5 continuing to move downward, the saw blade 6 cuts off the riser. During operation, no personnel need to approach the bearing housing to cut, improving operator safety. Simultaneously, the saw blade 6 can make stable cuts in the vertical direction, ensuring a flat cut surface, thus facilitating further processing on a CNC machine tool.

[0032] Specifically, in this embodiment, the saw blade 6 has a ring-shaped structure, and an active roller and a driven roller for driving the chain are rotatably arranged on the lifting frame 5. The saw blade 6 is wound between the active roller and the driven roller.

[0033] Specifically, in this embodiment, a guide column for guiding the lifting frame 5 to move up and down is fixedly installed on the operating table 1, and the lifting frame 5 is slidably mounted on the guide column. A cylinder for driving the lifting frame 5 to move up and down is also installed on the operating table 1. During the cutting process, the lifting frame 5 adopts a sawing machine structure in the prior art, the specific structure of which is prior art and will not be described here.

[0034] In some embodiments, the positioning component 3 described above may employ, for example... Figure 2 The structure shown. See also Figure 2The positioning component 3 includes a retaining wall 31 and positioning rods 32. The retaining wall 31 is fixedly installed on the fixed base 2, with the top surface of the fixed base 2 perpendicular to the retaining wall 31. Multiple positioning rods 32 are fixedly installed on the retaining wall 31, forming a limiting space to prevent the bearing seat from rolling on the operating table 1. Multiple square tubes are fixedly installed on the top of the fixed base 2, with one side of each tube flush to form the retaining wall 31. Multiple positioning rods 32 are fixedly installed on the square tubes, forming a limiting space to accommodate the bearing seat. When installing the bearing seat, it can be inserted into the limiting space, so that the end of the bearing seat away from the riser and gating point abuts against the retaining wall 31, thus limiting the bearing seat on the fixed base 2.

[0035] Specifically, in this embodiment, the bearing housing can be prevented from rolling on the fixed seat 2 by limiting the position of multiple positioning rods 32. At the same time, multiple lugs are provided on the outer side of one end of the bearing housing, and the positioning rods 32 can abut against the sides of the lugs to further limit the bearing housing.

[0036] In some embodiments, the fixing component 4 described above may be as follows: Figure 1 , Figure 2 The structure shown. See also... Figure 1 , Figure 2 The fixing component 4 includes hooks 41 and push-pull members 42. There are two hooks 41, both mounted on the fixing base 2. Each hook 41 has the freedom to move in a direction perpendicular to the retaining wall 31. The push-pull member 42 is mounted on the fixing base 2 and is used to pull the hooks 41 to move on the fixing base 2. The push-pull member 42 is a cylinder, with a mounting plate protruding from the outer wall of the bearing housing. The hooks 41 are used to hang on the mounting plate, and by pulling the push-pull member 42, the hooks 41 pull the bearing housing against the retaining wall 31, thereby fixing the bearing housing to the fixing base 2.

[0037] Specifically, in this embodiment, a support block for supporting the gating and riser is also fixedly installed on the top surface of the fixed base 2, so that the gating and riser can be suspended on the fixed base 2, which is convenient for the saw blade 6 to cut.

[0038] In some embodiments, the push-pull member 42 may be adopted as follows: Figure 2 , Figure 3 The structure shown. See also... Figure 2 , Figure 3A connecting plate 43 is fixedly mounted on the driving end of the push-pull component 42, and a pull rod 44 is fixedly mounted on the hook 41. The pull rod 44 passes through the connecting plate 43, and a fixing member for fixing to the connecting plate 43 is threaded onto the pull rod 44. The connecting plate 43 is fixedly mounted on the driving end of the push-pull component 42, and the pull rod 44 on the hook 41 is installed at both ends of the connecting plate 43. At least two fixing members, which are nuts, are threaded onto the pull rod 44, and nuts are provided on both sides of the connecting plate 43. The fixing members abut against both sides of the connecting plate 43, thereby achieving a fixed connection between the connecting plate 43 and the pull rod 44.

[0039] Specifically, in this embodiment, by adjusting the positions of the two fixing members on the pull rod 44, the relative positions of the two hooks 41 along the length of the pull rod 44 can be adjusted. When there are casting errors in the casting, the thickness of the mounting plate will be inconsistent. By adjusting the positions of the fixing members on the pull rod 44, the relative positions of a single hook 41 and the other hook 41 can be adjusted, so that both hooks 41 can effectively act on the corresponding mounting plate, allowing the bearing seat to stably abut against the retaining wall 31.

[0040] In some embodiments, the push-pull member 42 may be adopted as follows: Figure 1 , Figure 2 The structure shown. See also... Figure 1 , Figure 2 The fixed end of the push-pull component 42 has a degree of freedom to be adjusted along the pitch angle on the fixed base 2. A guide assembly 7 is also provided between the fixed base 2 and the pull rod 44 to guide the push-pull component 42 to rotate up and down. The fixed end of the push-pull component 42 can rotate along the pitch angle, so that when the hook 41 is pushed outward, the push-pull component 42 rotates upward through the guide assembly 7, thereby pulling out the bearing housing. When the hook 41 moves inward, the push-pull component 42 rotates downward, so that the hook 41 hooks the mounting plate and pulls the mounting plate towards the retaining wall 31. By rotating the push-pull component 42 up and down, the pull rod 44 on the hook 41 can be rotated up and down. After the pull rod 44 rotates upward, the hook 41 can be moved above the bearing housing, which facilitates the subsequent installation and removal of the bearing housing.

[0041] In some embodiments, the guide component 7 described above may employ, for example... Figure 3 The structure shown. See also Figure 3The guide assembly 7 includes a support roller 71 and a guide plate 72. The support roller 71 is rotatably mounted on the fixed base 2; the guide plate 72 is fixedly mounted on the bottom of the pull rod 44, with the support roller 71 located on the side of the guide plate 72 near the hook 41, and the side of the guide plate 72 near the support roller 71 is inclined with a chamfer. The support roller 71 is rotatably mounted on the fixed base 2 and is located directly below the pull rod 44. The guide plate 72 is also fixedly mounted on the lower side of the pull rod 44, and one side of the guide plate 72 is inclined with a chamfer, which is inclined from top to bottom away from the support roller 71. When the push-pull member 42 drives the pull rod 44 to move outward, the guide plate 72 moves to directly above the support roller 71, thereby causing the hook 41 to flip upward, facilitating the removal or installation of the bearing seat onto the fixed base 2.

[0042] Specifically, in this embodiment, when the pull rod 44 moves inward, the guide plate 72 disengages from the support roller 71, and the pull rod 44 abuts against the outer surface of the support roller 71, thereby causing the hook 41 to flip to the mounting plate on the bearing seat. The push-pull member 42 then pulls the pull rod 44 inward again, enabling the hook 41 to act on the bearing seat. The flipping of the fixed end of the push-pull member 42 can be achieved during the movement of the pull rod 44, requiring no additional operation.

[0043] In some embodiments, the hook 41 described above can be as follows: Figure 2 The structure shown. See also Figure 2 A limiting rod 411 for limiting the bearing seat to the fixed seat 2 is fixedly installed between the two hooks 41. The two ends of the limiting rod 411 are respectively fixedly installed on the two hooks 41. When the two hooks 41 are flipped downward, the limiting rod 411 can abut against the outer surface of the bearing seat, thereby limiting the bearing seat to the fixed seat 2 and further improving the stability of the bearing seat on the fixed seat 2 during the cutting process.

[0044] In some embodiments, the aforementioned fixing base 2 may be adopted as follows: Figure 1 The structure shown. See also Figure 1 The fixed seat 2 has a degree of freedom to adjust its position on the operating table 1 in a direction perpendicular to the retaining wall 31. Defined as the first direction, the fixed seat 2 is slidably mounted on the operating table 1 along this first direction. Multiple push rods are threaded onto the operating table 1, with push rods on both sides of the fixed seat 2 along the first direction. By adjusting the position of the push rods, the position of the fixed seat 2 on the operating table 1 along the first direction can be adjusted. This allows for fine-tuning the position of the fixed seat 2 before cutting the riser to align the cutting position of the saw blade 6, preventing damage to the useful parts of the bearing housing during cutting, minimizing riser material, and improving subsequent processing efficiency.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
