Description

Technical Field

[0001] This invention belongs to the field of casting processing technology, and specifically relates to an integrated processing device for threaded holes in bearing seats. Background Technology

[0002] Large bearing housings are typically cast, and then machined using machining equipment to create the internal bearing mounting holes and threaded holes on the end faces. Currently, the machining process for bearing housings involves marking the positions of the threaded holes on a machine tool after machining the bearing mounting holes and end faces. The bearing housing is then moved to a drilling machine for drilling. However, the drilling machine processes the threaded holes one by one, resulting in low efficiency. While integrated threading machines are available to improve production efficiency, they often cause misalignment between the bearing mounting holes and the threaded holes after machining, affecting the subsequent installation of the bearing housing. Summary of the Invention

[0003] This invention provides an integrated machining device for threaded holes in bearing housings, which aims to solve the problem that existing integrated machining equipment for threaded holes in bearing housings is not able to guarantee the relative position of the threaded hole and the bearing mounting hole, resulting in poor machining accuracy.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: to provide an integrated machining device for threaded holes in bearing housings, comprising: A machining platform, wherein a drilling mechanism, a chamfering mechanism and a tapping mechanism are sequentially arranged along a first direction; A clamping table is mounted on the machining platform and has a degree of freedom to be adjusted along a first direction on the machining platform. A positioning plate for positioning the bearing seat is mounted on the clamping table. A stop key, installed on the clamping table, is used to position one side of the bearing housing; A pressing mechanism is provided on the clamping platform for fixing the bearing seat to the clamping platform.

[0005] In one possible implementation, the drilling mechanism includes: A drilling platform is mounted on the processing platform. The drilling platform has a vertical degree of freedom to move on the processing platform, and a drill bit for drilling is rotatably mounted on the drilling platform. The pressing plate is slidably disposed on the drilling platform in the vertical direction and can abut against the end of the bearing seat for pressing on the end face of the bearing seat; An elastic element is installed between the drilling platform and the pressing plate to push the pressing plate against the end face of the bearing seat.

[0006] In one possible implementation, a plurality of positioning blocks are fixedly installed on the bottom of the pressing plate, and the outer side of the positioning blocks is an arc-shaped surface for positioning the inner hole of the bearing seat.

[0007] In one possible implementation, the outer side of the positioning block is provided with an adjustment platform for abutting against the end face of the bearing seat, and the adjustment platform is provided protruding from the bottom surface of the pressing plate.

[0008] In one possible implementation, the adjustment platforms on the outer sides of the plurality of positioning blocks are located on the same plane and are arranged perpendicular to the axis of the positioning disk.

[0009] In one possible implementation, the pressing mechanism includes: The support base is fixedly installed on the clamping platform; A support rod, one end of which is hinged to the support base; A fixed plate is hinged to the other end of the support rod in the middle. A pusher is mounted on the support base, and the driving end of the pusher is hinged to one end of the fixed plate.

[0010] In one possible implementation, the pressing plate is provided with a clearance to prevent the fixing plate from flipping up and down.

[0011] In one possible implementation, an air blowing mechanism is further provided between the chamfering mechanism and the tapping mechanism, the air blowing mechanism comprising: An air blowing plate is slidably mounted on the processing platform in a vertical direction; The number and relative position of the air nozzles correspond one-to-one with the threaded holes on the bearing housing; A push-pull component is mounted on the processing platform, and the drive end of the push-pull component is fixedly connected to the air blowing plate.

[0012] In one possible implementation, the top of the pressing plate is provided with a liquid filling tank, the inside of the liquid filling tank is provided with a guide hole for guiding the drill bit, and the pressing plate is also equipped with a liquid filling pipe for adding cutting fluid into the liquid filling tank.

[0013] In one possible implementation, the machining platform is further equipped with a side milling mechanism for machining the side surface of the bearing housing, the side milling mechanism comprising: A movable seat is mounted on the processing platform, and the position of the movable seat on the processing platform has a degree of freedom to be adjusted along a second direction, which is perpendicular to the first direction. A milling cutter, rotatably mounted on the movable seat, is used to machine the outer surface of the bearing housing.

[0014] The solution shown in this application embodiment, compared with the prior art, features a machining platform with its length direction as the first direction.

In this application, a positioning plate is installed on the clamping table. When the bearing housing is installed on the clamping table, the positioning plate slides into the bearing mounting hole on the bearing housing. This positions the bearing housing on the clamping table and, through a key, abuts against the right-angled edge of the bearing housing to prevent rotation on the clamping table. This ensures the stability of the relative position between the threaded hole and the bearing mounting hole on the bearing housing during subsequent threaded hole machining, thereby improving machining accuracy and ensuring the stability of the bearing housing's installation position on the vehicle.

[0017] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention 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 invention and are not intended to limit the present invention.

[0018] Please refer to the following: Figures 1 to 6 The present invention will now describe the integrated machining device for bearing housing threaded holes. The integrated machining device for bearing housing threaded holes includes a machining platform 1, a clamping table 2, a stop key 22, and a pressing mechanism 23. A drilling mechanism 3, a chamfering mechanism 4, and a tapping mechanism 5 are sequentially arranged on the machining platform 1 along a first direction. The clamping table 2 is mounted on the machining platform 1 and has a degree of freedom to adjust its position along the first direction. A positioning disc 21 for positioning the bearing housing is mounted on the clamping table 2. The stop key 22 is mounted on the clamping table 2 for positioning one side of the bearing housing. The pressing mechanism 23 is disposed on the clamping table 2 for fixing the bearing housing to the clamping table 2.

[0019] The bearing housing threaded hole integrated machining device provided in this embodiment, compared with the prior art, is designed with a machining platform 1, the length direction of which is the first direction. A drilling mechanism 3, a chamfering mechanism 4, and a tapping mechanism 5 are sequentially arranged on the machining platform 1 along the first direction. A clamping table 2 is also installed on the machining platform 1. The clamping table 2 can move along the first direction on the machining platform 1 and sequentially passes through the drilling mechanism 3 to machine the bottom hole of the threaded hole, then through the chamfering mechanism 4 to chamfer the opening of the bottom hole, and finally through the tapping mechanism 5 to machine the threaded hole. In this application, a positioning plate 21 is installed on the clamping table 2. When the bearing housing is installed on the clamping table 2, the positioning plate 21 slides into the bearing mounting hole on the bearing housing. This allows for positioning of the bearing housing on the clamping table 2, and a stop key 22 abuts against the right-angled edge of the outer side of the bearing housing to prevent the bearing housing from rotating on the clamping table 2. This ensures the stability of the relative position between the threaded hole on the bearing housing and the bearing mounting hole during subsequent machining of the threaded hole, thereby improving machining accuracy and ensuring the stability of the bearing housing's installation position on the vehicle.

[0020] Preferably, in this embodiment, the stop key 22 is slidably disposed on the clamping table 2 along the first direction, and a bolt for fixing the stop key 22 is threadedly connected to the clamping table 2. An elongated hole for mounting the bolt is provided on the stop key 22, so that the position of the stop key 22 can be adjusted so that the stop key 22 effectively abuts against the side wall of the bearing seat, thereby preventing the bearing seat from rotating on the clamping table 2.

[0021] Specifically, in this embodiment, a guide post for guiding the movement of the clamping table 2 is installed on the machining platform 1, a guide sleeve that slides with the guide post is installed on the clamping table 2, and a lead screw is rotatably mounted on the machining platform 1. A threaded sleeve that is threadedly connected to the lead screw is fixedly installed on the clamping table 2. The movement of the clamping table 2 is achieved by rotating the lead screw.

[0022] In some embodiments, the drilling mechanism 3 described above can be as follows: Figure 1 , Figure 3 The structure shown. See also... Figure 1 , Figure 3 The drilling mechanism 3 includes a drilling platform 31, a pressing plate 32, and an elastic element 33. The drilling platform 31 is mounted on the processing platform 1 and has the freedom to move vertically on the processing platform 1. A drill bit for drilling is rotatably mounted on the drilling platform 31. The pressing plate 32 is slidably mounted on the drilling platform 31 in the vertical direction and can abut against the end of the bearing seat for pressing against the end face of the bearing seat. The elastic element 33 is installed between the drilling platform 31 and the pressing plate 32 for pushing the pressing plate 32 to press against the end face of the bearing seat. A lead screw is rotatably mounted on the processing platform 1, and a threaded sleeve threadedly connected to the lead screw is fixedly mounted on the drilling platform 31, thereby allowing the drilling platform 31 to move vertically.

[0023] Specifically, in this embodiment, multiple chucks for mounting drill bits are rotatably mounted on the drilling platform 31. Each chuck is fixedly equipped with a driven gear. A driving gear is also rotatably mounted on the drilling platform 31. The driving gears mesh with the corresponding driven gears of the multiple chucks, thereby enabling a single driving gear to drive multiple driven gears to rotate synchronously. The driving gear is driven to rotate on the drilling platform 31 by a motor.

[0024] Specifically, in this embodiment, the chamfering mechanism 4 and the tapping mechanism 5 have the same structure as the drilling mechanism 3, except that the pressing plate 32 is not present. The only difference is that the chamfering cutter or tap is replaced in the chuck.

[0025] Preferably, in this embodiment, a pressing plate 32 is installed below the drilling platform 31. The pressing plate 32 can press against the bearing seat, further enhancing the stability of the bearing seat. The drill bit penetrates the pressing plate 32 to perform drilling operations. Multiple guide posts are fixedly installed on the drilling platform 31, and guide sleeves that slide with the guide posts are fixedly installed on the pressing plate 32. By installing an elastic element 33 between the pressing plate 32 and the drilling platform 31, the pressing plate 32 can be kept pressed against the end face of the bearing seat during the downward movement of the drilling platform 31.

[0026] Preferably, in this embodiment, a guide rod for guiding and supporting the elastic element 33 is fixedly installed on the pressing plate 32, and the guide rod is slidably disposed on the drilling platform 31.

[0027] In some embodiments, the pressing plate 32 may be as follows: Figure 3 , Figure 4 The structure shown. See also... Figure 3 , Figure 4 Multiple positioning blocks 34 are fixedly installed on the bottom of the pressing plate 32. The outer side of each positioning block 34 is an arc-shaped surface used for positioning the inner hole of the bearing seat. Multiple positioning blocks 34 with arc-shaped outer surfaces are fixedly installed on the bottom of the pressing plate 32. The arc-shaped outer surfaces of the multiple positioning blocks 34 are coaxially arranged, and the multiple positioning blocks 34 form a positioning structure for positioning the inner hole of the bearing seat. When the clamping table 2 moves to the drilling mechanism 3, located below the pressing plate 32, it moves downward via the drilling platform 31, and the positioning blocks 34 at the bottom of the pressing plate 32 preferably slide into the bearing hole inside the bearing seat. Simultaneously, when the clamping table 2 moves to the machining position of the drilling mechanism 3, the positioning disk 21 on the clamping table 2 is coaxially arranged with the arc-shaped surfaces of the multiple positioning blocks 34.

[0028] Specifically, in this embodiment, the axis of the arc-shaped surface on the positioning block 34 is set vertically and parallel to the axis of the drill bit on the drilling platform 31. Through the positioning block 34 combined with the positioning disk 21, the stability of the bearing housing in the machining position can be improved. Simultaneously, it ensures that the threaded bottom hole to be machined remains axially parallel to the bearing mounting hole on the bearing housing, guaranteeing the stability of the bearing housing during subsequent vehicle installation.

[0029] In some embodiments, the positioning block 34 may employ, for example... Figure 4 The structure shown. See also Figure 4 The positioning block 34 has a protruding adjusting platform 341 on its outer side for abutting against the end face of the bearing seat. The adjusting platform 341 protrudes from the bottom surface of the pressing plate 32. The adjusting platform 341 protrudes from the end of the positioning block 34 near the pressing plate 32. The adjusting platform 341 abuts against the bottom surface of the pressing plate 32 and protrudes from the bottom surface of the pressing plate 32, so that when the pressing plate 32 moves downward, the adjusting platform 341 is supported on the machined end face of the bearing seat. This creates a certain gap between the pressing plate 32 and the machined end face of the bearing seat, allowing iron filings generated during drilling to be discharged through the gap. This facilitates the discharge of iron filings and prevents them from moving onto the pressing plate 32, thus reducing the workload of subsequent iron filings cleaning.

[0030] In some embodiments, the positioning block 34 may employ, for example... Figure 4 The structure shown. See also Figure 4The adjusting platforms 341 on the outer sides of multiple positioning blocks 34 are located on the same plane and are perpendicular to the axis of the positioning disk 21. The positioning blocks 34 and the adjusting platforms 341 are integrally formed. The sides of the positioning blocks 34 and the adjusting platforms 341 closest to the pressing plate 32 are located on the same plane, so that the positioning blocks 34 and the adjusting platforms 341 can be stably abutted against the bottom surface of the pressing plate 32. At the same time, the adjusting platforms 341 on the multiple positioning blocks 34 have the same thickness, so that the bottom surfaces of the adjusting platforms 341 on the multiple support blocks are located on the same plane and are perpendicular to the axis of the drill bit. Thus, when the adjusting platforms 341 on the outer sides of the multiple positioning blocks 34 abut against the machined end face of the bearing seat, the end face of the bearing seat can remain parallel to the bottom surfaces of the multiple adjusting platforms 341. At the same time, it ensures that the threaded bottom hole machined on the bearing seat later remains perpendicular to the machined end face of the bearing seat.

[0031] Preferably, in this embodiment, to facilitate the disassembly and installation of the bearing housing on the clamping table 2, and to ensure the smooth sliding of the positioning block 34 into the bearing housing, the positioning plate 21 and the bearing mounting hole at the bottom of the bearing housing are in clearance fit, and the outer arc surfaces of the multiple positioning blocks 34 and the mounting holes at the top of the bearing housing are also in clearance fit. Due to the presence of clearance, the bearing housing may easily become tilted. By pressing the multiple adjusting platforms 341 before drilling, the tilt angle of the bearing housing can be adjusted, preventing the threaded bottom hole from tilting during subsequent machining, which could affect subsequent tapping or bearing housing installation.

[0032] Specifically, in this embodiment, the gap between a single positioning block 34 and the mounting hole on the top of the bearing seat is 0.02~0.05mm.

[0033] In some embodiments, the pressing mechanism 23 described above may employ, for example... Figure 1 , Figure 2 The structure shown. See also... Figure 1 , Figure 2The pressing mechanism 23 includes a support base 231, a support rod 232, a fixing plate 233, and a pushing member 234. The support base 231 is fixedly mounted on the clamping table 2; one end of the support rod 232 is hinged to the support base 231; the middle part of the fixing plate 233 is hinged to the other end of the support rod 232; the pushing member 234 is mounted on the support base 231, and the driving end of the pushing member 234 is hinged to one end of the fixing plate 233. Support bases 231 are provided on both sides of the positioning plate 21 along the first direction. The support bases 231 are fixedly mounted on the clamping table 2. The fixed end of the pushing member 234 is fixedly mounted on the top of the support base 231, and the driving end of the pushing member 234 is hinged to one end of the fixing plate 233. The other end of the fixing plate 233 is used to press against the machined end face of the top of the bearing seat. Furthermore, a support rod 232 is hinged between the fixed plate 233 and the support base 231. During use, the drive end of the pusher 234 extends and pushes the fixed plate 233 to swing, thereby pressing the bearing seat onto the clamping platform. The structure is simple and facilitates automated clamping.

[0034] In some embodiments, the pressing plate 32 may be as follows: Figure 3 , Figure 4 The structure shown. See also... Figure 3 , Figure 4 The pressing plate 32 is provided with a clearance to allow the fixing plate 233 to flip up and down. The pressing plate 32 is provided with a clearance to allow the fixing plate 233 to flip up and down, so that the clamping platform can be moved to the machining position of the drilling mechanism 3. After the pressing plate 32 presses against the machining end face of the top of the bearing seat, the fixing plate 233 is used to press it.

[0035] Specifically, in this embodiment, during the machining of the bearing housing, the bearing housing can first be initially positioned using the positioning plate 21, and then preliminarily positioned using the stop key 22, so that the bearing housing can be stably placed on the clamping table 2. Then, the clamping table 2 moves along the first direction to the drilling mechanism 3. After moving into position, the drilling platform 31 and the pressing plate 32 move downward together, so that the pressing plate 32 presses against the machining end face of the top of the bearing housing and applies a certain force. The position of the bearing housing is then adjusted a second time using the positioning block 34 on the pressing plate 32 and the adjusting platform 341, and then the bearing housing is pressed tightly by the pressing plate 32 to fix the bearing housing.

[0036] Using the above method, on the one hand, it facilitates further adjustment of the bearing housing's position at drilling mechanism 3; on the other hand, when clamping and fixing the bearing housing, the bearing housing is in its final adjusted position via pressing plate 32. Furthermore, when fixing plate 233 presses against the bearing housing, pressing plate 32 remains pressed against the machined top surface of the bearing housing. After drilling is completed, subsequent chamfering and tapping processes will ensure the stability of the relative position of the bearing housing.

[0037] In some embodiments, the blowing mechanism 6 described above can be as follows: Figure 5 The structure shown. See also Figure 5 An air blowing mechanism 6 is also provided between the chamfering mechanism 4 and the tapping mechanism 5. The air blowing mechanism 6 includes an air blowing plate 61, an air blowing nozzle 62, and a push-pull component 63. The air blowing plate 61 is slidably mounted on the machining platform 1 in the vertical direction; the number and relative position of the air blowing nozzles 62 correspond one-to-one with the threaded holes on the bearing seat; the push-pull component 63 is mounted on the machining platform 1, and the driving end of the push-pull component 63 is fixedly connected to the air blowing plate 61. In this embodiment, when machining the threaded holes on the bearing seat, some threaded holes are blind holes. When machining the bottom hole, iron filings will remain inside the threaded bottom hole, which will affect the normal rotation of the tap during the tapping process, and in severe cases, may even cause the tap to break. The air blowing mechanism 6 is provided behind the chamfering mechanism 4. The air blowing nozzles 62 can blow out the iron filings inside the threaded bottom hole to avoid affecting the subsequent tapping operation.

[0038] Specifically, in this embodiment, a guide frame is fixedly installed on the processing platform 1, and the air blowing plate 61 is slidably mounted on the guide frame in the vertical direction. A cylinder for driving the air blowing plate 61 to move up and down is also installed on the guide frame. When the clamping table 2 moves to the work position of the air blowing mechanism 6, the cylinder drives the air blowing plate 61 to move downward. At this time, the air outlets of the multiple air nozzles 62 are directly facing the machined threaded bottom hole, and air is blown into the inside to blow out the internal iron filings. After the blowing is completed, the cylinder drives the air blowing plate 61 to move upward. The iron filings cleaning operation is completed.

[0039] In some embodiments, the pressing plate 32 may be as follows: Figure 3 The structure shown. See also Figure 3 The pressure plate 32 has a fluid filling tank at its top, with a guide hole inside for guiding the drill bit. A fluid filling pipe for adding cutting fluid into the filling tank is also installed on the pressure plate. An annular rib 321 is welded and fixedly installed on the top of the pressure plate 32, forming the fluid filling tank with the pressure plate 32. A guide hole for guiding the drill bit is provided on the mounting plate, located inside the annular rib 321. Cutting fluid can be added into the filling tank through the fluid filling pipe, and the cutting fluid flows onto the drill bit through the guide hole, thus assisting the drill bit in drilling operations.

[0040] Specifically, in this embodiment, the design of the bottom adjustment platform 341 of the pressing plate 32 allows the pressing plate 32 to be spaced apart from the top machining end face of the bearing seat, thereby reducing the possibility of iron filings moving into the fluid filling tank and avoiding affecting the flow of cutting fluid inside the fluid filling tank.

[0041] In some embodiments, the processing platform 1 described above may employ, for example... Figure 5 , Figure 6 The structure shown. See also... Figure 5 , Figure 6 The machining platform 1 is also equipped with a side milling mechanism 7 for machining the side surface of the bearing housing. The side milling mechanism 7 includes a movable seat 71 and a milling cutter 72. The movable seat 71 is mounted on the machining platform 1, and its position on the machining platform 1 has a degree of freedom for adjustment along a second direction, which is perpendicular to the first direction. The milling cutter 72 is rotatably mounted on the movable seat 71 for machining the outer surface of the bearing housing. A lead screw is rotatably mounted on the machining platform 1, and a threaded sleeve threadedly connected to the lead screw is fixedly mounted on the movable seat 71. This allows adjustment of the position of the movable seat 71 along the second direction on the machining platform 1. Simultaneously, the milling cutter 72 is also rotatably mounted on the movable seat 71. After the threaded hole is machined, the unmachined surface of the bearing housing side can be machined using the milling cutter 72.

[0042] Specifically, in this embodiment, two sets of pressing mechanisms 23 are arranged at intervals along the first direction on the clamping table 2. This avoids interference between the milling cutter 72 and the pressing mechanism 23 during side milling.

[0043] Specifically, in this embodiment, after the conventional bearing housing is machined at both ends, it is necessary to realign and reposition it to machine the side surface of the bearing housing. However, by using the integrated machining device for the bearing housing threaded hole in this application, the machining of the threaded hole and the side surface can be completed after the bearing mounting hole and both ends of the bearing housing are machined, reducing the number of processes and improving the machining efficiency.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
