When the threaded hole is processed later, the relative position stability of the threaded hole on the bearing seat and the bearing mounting hole is ensured, thereby improving the processing precision and ensuring the stability of the installation position of the bearing seat on the vehicle later.

[0042] Preferably, in the embodiment, the stop key 22 is slidably arranged on the clamping table 2 in the first direction, and a bolt for fixing the stop key 22 is threadedly connected on the clamping table 2, a long circular hole for mounting the bolt is arranged on the stop key 22, the position of the stop key 22 can be adjusted, and the stop key 22 is effectively abutted against the side wall of the bearing seat to avoid rotation of the bearing seat on the clamping table 2.

[0043] Specifically, in the embodiment, guide columns for guiding movement of the clamping table 2 are mounted on the machining platform 1, guide sleeves slidably matched with the guide columns are mounted on the clamping table 2, and a lead screw is rotatably arranged on the machining platform 1, and a threaded sleeve threadedly connected with the lead screw is fixedly mounted on the clamping table 2. Movement of the clamping table 2 is realized by rotation of the lead screw.

[0044] In some embodiments, the drilling mechanism 3 described above can adopt the structure as shown in Figure 1 、 Figure 3 . Referring to Figure 1 、 Figure 3 , the drilling mechanism 3 comprises a drilling platform 31, a pressing plate 32 and an elastic member 33. The drilling platform 31 is mounted on the machining platform 1, the position of the drilling platform 31 on the machining platform 1 has a degree of freedom of movement in the vertical direction, and a drill bit for drilling is rotatably arranged on the drilling platform 31; the pressing plate 32 is slidably arranged on the drilling platform 31 in the vertical direction, and can abut against the end of the bearing seat for pressing on the end face of the bearing seat; the elastic member 33 is mounted between the drilling platform 31 and the pressing plate 32, and is used to push the pressing plate 32 to press on the end face of the bearing seat. A lead screw is rotatably arranged on the machining platform 1, and a threaded sleeve threadedly connected with the lead screw is fixedly mounted on the drilling platform 31, so that the drilling platform 31 can move in the vertical direction.

[0045] Specifically, in the embodiment, a plurality of chuck heads for mounting drill bits are also rotatably arranged on the drilling platform 31, a driven gear is fixedly mounted on each of the plurality of chuck heads, and a driving gear is rotatably arranged on the drilling platform 31, the driving gear and the driven gears corresponding to the plurality of chuck heads are rotatably arranged in meshing relationship, so that a single driving gear can drive the plurality of driven gears to rotate synchronously. The driving gear is driven to rotate on the drilling platform 31 by a motor.

[0046] Specifically, in the embodiment, the structures of the chamfering mechanism 4 and the tapping mechanism 5 are the same as those of the drilling mechanism 3 except that there is no pressing plate 32. Only the chamfering cutter or the tap is replaced on the chuck head.

[0047] Preferably, in the embodiment, a pressing plate 32 is installed below the drilling platform 31, which can be pressed onto the bearing seat through the pressing plate 32, further enhancing the stability of the bearing seat fixation. The drill bit penetrates the pressing plate 32 to perform drilling operations. A plurality of guide columns are fixedly installed on the drilling platform 31, and a plurality of guide sleeves that slidingly cooperate with the guide columns are fixedly installed on the pressing plate 32. By installing an elastic member 33 between the pressing plate 32 and the drilling platform 31, the pressing plate 32 can always be pressed on the end face of the bearing seat during the downward movement of the drilling platform 31.

[0048] Preferably, in the embodiment, a guide rod for guiding and supporting the elastic member 33 is fixedly installed on the pressing plate 32, and the guide rod is slidingly arranged on the drilling platform 31.

[0049] In some embodiments, the above-mentioned pressing plate 32 can adopt the structure as shown in Figure 3 、 Figure 4 . Referring to Figure 3 、 Figure 4 , a plurality of positioning blocks 34 are fixedly installed on the bottom of the pressing plate 32, and the outer side of the positioning block 34 is an arc surface for positioning the inner hole of the bearing seat. A plurality of positioning blocks 34 are fixedly installed on the bottom of the pressing plate 32, and the arc surfaces on the outer sides of the plurality of positioning blocks 34 are coaxially arranged, and the plurality of 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, it is located below the pressing plate 32, and the positioning blocks 34 at the bottom of the pressing plate 32 are preferably slid into the bearing hole inside the bearing seat by moving the drilling platform 31 downward. At the same time, when the clamping table 2 moves to the machining position of the drilling mechanism 3, the positioning disc 21 on the clamping table 2 is coaxially arranged with the arc surfaces of the plurality of positioning blocks 34.

[0050] Specifically, in the embodiment, the axis of the arc surface on the positioning block 34 is arranged in the vertical direction and parallel to the axis of the drill bit on the drilling platform 31. Through the positioning of the positioning block 34 combined with the positioning disc 21, on the one hand, the stability of the bearing seat in the machining position can be improved. At the same time, the axis of the threaded hole to be machined can be kept parallel to the bearing mounting hole on the bearing seat, ensuring the stability of the bearing seat during the later vehicle installation process.

[0051] In some embodiments, the above-mentioned positioning block 34 can adopt the structure as shown in Figure 4 . Referring to Figure 4The outer side of the positioning block 34 is provided with a regulating platform 341 for abutting to the end face of the bearing seat, and the bottom surface of the regulating platform 341 is provided with a protrusion for pressing the pressing plate 32. The regulating platform 341 is provided with a protrusion at one end of the positioning block 34 close to the pressing plate 32. The regulating platform 341 abuts on the bottom surface of the pressing plate 32, and the regulating platform 341 protrudes from the bottom surface of the pressing plate 32, so that when the pressing plate 32 moves downward, the regulating platform 341 is supported on the machined end face of the bearing seat. The pressing plate 32 has a certain gap with the machined end face of the bearing seat, so that the iron filings generated during the drilling process can be discharged through the gap, on the one hand, facilitating the discharge of the iron filings, and on the other hand, avoiding the iron filings moving to the pressing plate 32, thereby increasing the workload of subsequent iron filings cleaning.

[0052] In some embodiments, the positioning block 34 described above can adopt the structure as shown in Figure 4 Figure 4 The regulating platforms 341 of the plurality of positioning blocks 34 are located on the same plane and are perpendicular to the axis of the positioning disc 21. The positioning block 34 and the regulating platform 341 are integrally formed. The side of the positioning block 34 and the regulating platform 341 close to the pressing plate 32 is located on the same plane, so that the positioning block 34 and the regulating platform 341 can stably abut on the bottom surface of the pressing plate 32. At the same time, the thicknesses of the regulating platforms 341 on the plurality of positioning blocks 34 are the same, so that the bottom surfaces of the regulating platforms 341 on the plurality of supporting blocks are located on the same plane and are perpendicular to the axis of the drill bit. Therefore, when the regulating platforms 341 on the outer sides of the plurality of positioning blocks 34 abut on the machined end face of the bearing seat, the end face of the bearing seat can be parallel to the bottom surfaces of the plurality of regulating platforms 341. At the same time, it is ensured that the threaded bottom hole machined on the bearing seat later is perpendicular to the machined end face of the bearing seat.

[0053] Preferably, in order to facilitate the dismounting and mounting of the bearing seat on the clamping table 2 and the smoothness of the positioning block 34 sliding into the bearing seat, the bearing mounting hole at the bottom of the positioning disc 21 and the bearing seat is a clearance fit, and the outer arc surface of the plurality of positioning blocks 34 and the mounting hole at the top of the bearing seat are a clearance fit. Due to the existence of the clearance, the bearing seat is prone to be inclined. By extruding the plurality of regulating platforms 341 before drilling, the inclination angle of the bearing seat can be adjusted, so as to avoid the threaded bottom hole machined later being inclined, thereby affecting the tapping or the mounting of the bearing seat.

[0054] Specifically, in the present embodiment, the clearance between the single positioning block 34 and the mounting hole at the top of the bearing seat is 0.02-0.05 mm.

[0055] In some embodiments, the pressing mechanism 23 described above can adopt the structure as shown in Figure 1 Figure 2 Figure 1 Figure 2 ​​​​The pressing mechanism 23 comprises a support seat 231, a support rod 232, a fixed plate 233 and a pushing piece 234. The support seat 231 is fixedly installed on the clamping table 2; the support rod 232 is hingedly arranged at one end on the support seat 231; the fixed plate 233 is hingedly connected at the middle to the other end of the support rod 232; the pushing piece 234 is installed on the support seat 231, and the driving end of the pushing piece 234 is hingedly connected to one end of the fixed plate 233. The support seat 231 is fixedly installed on the clamping table 2 on both sides of the positioning disc 21 along the first direction, the fixed end of the pushing piece 234 is fixedly installed on the top of the support seat 231, the driving end of the pushing piece 234 is hingedly arranged at one end of the fixed plate 233, and the other end of the fixed plate 233 is used to press against the machining end face on the top of the bearing seat. And the support rod 232 is hingedly arranged between the fixed plate 233 and the support seat 231, in use, the driving end of the pushing piece 234 is extended and pushes the fixed plate 233 to swing to press the bearing seat against the clamping platform. The structure is simple and convenient for automatic pressing.

[0056] In some embodiments, the pressing plate 32 can adopt the structure as shown in Figure 3 、 Figure 4 . Referring to Figure 3 、 Figure 4 , the pressing plate 32 is provided with a position for avoiding the up-down flipping of the fixed plate 233. The pressing plate 32 is provided with a position for avoiding the up-down flipping of the fixed plate 233, so that when the clamping platform moves to the machining position of the drilling mechanism 3, the pressing plate 32 can be pressed against the machining end face on the top of the bearing seat, and then the fixed plate 233 can be used for pressing.

[0057] Specifically, in this embodiment, when the bearing seat is machined, the bearing seat can be initially positioned by the positioning disc 21, and the initial positioning is given by the stop key 22, so that the bearing seat can be stably placed on the clamping table 2, then the clamping table 2 moves to the drilling mechanism 3 along the first direction. After moving to the position, the drilling platform 31 moves downward together with the pressing plate 32, so that the pressing plate 32 is pressed against the machining end face on the top of the bearing seat and a certain force is applied. The position of the bearing seat is adjusted again by the positioning block 34 and the adjusting platform 341 on the pressing plate 32, then the bearing seat is pressed by the pressing plate 32 to realize the fixation of the bearing seat.

[0058] By using the above method, on the one hand, the position of the bearing seat at the drilling mechanism 3 can be further adjusted, and on the other hand, when the bearing seat is clamped and fixed, the bearing seat is in the position finally adjusted by the pressing plate 32. And when the fixed plate 233 presses the bearing seat, the pressing plate 32 is always pressed against the machining end face on the top of the bearing seat. After the drilling is completed, the subsequent chamfering and tapping machining can ensure the stability of the relative position of the bearing seat.

[0059] In some embodiments, the above blowing mechanism 6 can adopt the structure as shown in Figure 5 Referring to Figure 5 , the chamfering mechanism 4 and the tapping mechanism 5 are further provided with the blowing mechanism 6, which includes a blowing plate 61, a blowing nozzle 62 and a push-pull piece 63. The blowing plate 61 is slidingly arranged on the machining platform 1 in the vertical direction; the blowing nozzle 62 corresponds to the threaded holes on the bearing seat in number and relative position; and the push-pull piece 63 is installed on the machining platform 1, and the driving end of the push-pull piece 63 is fixedly connected to the blowing plate 61. In this embodiment, when machining the threaded holes on the bearing seat, some of the threaded holes are blind holes. When machining the bottom holes, iron filings will be left inside the threaded bottom holes, which will affect the normal rotation of the tap during tapping, and in severe cases, it will also cause the tap to break. The blowing mechanism 6 is provided behind the chamfering mechanism 4, and the blowing nozzle 62 can blow out the iron filings inside the threaded bottom holes, avoiding affecting the subsequent tapping operation.

[0060] Specifically, in this embodiment, a guide frame is fixedly installed on the machining platform 1, the blowing plate 61 is slidingly arranged on the guide frame in the vertical direction, and a cylinder for driving the blowing plate 61 to move up and down is also installed on the guide frame. When the clamping table 2 moves to the working position of the blowing mechanism 6, the cylinder drives the blowing plate 61 to move downward, at this time, the gas outlets of the plurality of blowing nozzles 62 are opposite to the machined threaded bottom holes and blow the inside to blow out the internal iron filings, and after the blowing is completed, the cylinder drives the blowing plate 61 to move upward. Complete the operation of cleaning the iron filings.

[0061] In some embodiments, the above pressing plate 32 can adopt the structure as shown in Figure 3 Referring to Figure 3 , the top of the pressing plate 32 is provided with a liquid adding groove, the inside of the liquid adding groove is provided with a guide hole for guiding the drill, and the pressing plate is further provided with a liquid adding pipe for adding cutting fluid to the inside of the liquid adding groove. An annular rib plate 321 is fixedly installed on the top of the pressing plate 32 by welding, and the annular rib plate 321 and the pressing plate 32 form the liquid adding groove. A guide hole for guiding the drill is provided on the mounting plate, the guide hole is located inside the annular rib plate 321, cutting fluid can be added to the inside of the liquid adding groove through the liquid adding pipe, and the cutting fluid flows down to the drill through the guide hole, thereby assisting the drill to drill holes.

[0062] Specifically, in this embodiment, by designing the pressing plate 32 and the bottom machining end face of the bearing seat to be spaced apart through the bottom adjusting platform 341 of the pressing plate 32, the possibility of iron filings moving to the inside of the liquid adding groove can be reduced, thereby avoiding affecting the circulation of cutting fluid inside the liquid adding groove.

[0063] In some embodiments, the above machining platform 1 can adopt the structure as shown in Figure 5 , Figure 6 Referring to Figure 5 ,Figure 6 The machining platform 1 is further provided with a side milling mechanism 7 for machining the side surface of the bearing seat. The side milling mechanism 7 comprises a moving seat 71 and a milling cutter 72. The moving seat 71 is installed on the machining platform 1, and the position of the moving seat 71 on the machining platform 1 has a degree of freedom in the second direction, which is perpendicular to the first direction. The milling cutter 72 is rotatably arranged on the moving seat 71, and is used for machining the outer side surface of the bearing seat. A screw is rotatably arranged on the machining platform 1, and a threaded sleeve is fixedly arranged on the moving seat 71 and is threadedly connected with the screw. Thus, the position of the moving seat 71 on the machining platform 1 in the second direction can be adjusted. Meanwhile, the milling cutter 72 is also rotatably arranged on the moving seat 71. After the threaded hole is machined, the milling cutter 72 can be used to machine the side surface of the bearing seat.

[0064] Specifically, in the embodiment, two groups of pressing mechanisms 23 are arranged on the clamping table 2 along the first direction. Thus, the milling cutter 72 and the pressing mechanisms 23 can be prevented from interfering with each other during side milling.

[0065] Specifically, in the embodiment, after the two end surfaces of the conventional bearing seat are machined, the bearing seat needs to be repositioned for machining the side surface of the bearing seat. However, the bearing seat threaded hole integrated machining device in the application can complete the machining of the threaded hole and the side surface of the bearing seat after the bearing mounting hole and the two end surfaces of the bearing seat are machined, thereby reducing the process flow and improving the machining efficiency.

[0066] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
