Description

Technical Field

[0001] The invention relates to the technical field of bearing saddle processing equipment, and in particular to a tooling for multi-faceted milling of a bearing saddle and a use method thereof. Background Art

[0002] The load saddle is an important component in the railway vehicle bogie, mainly used for the load bearing of the wheelset bearing. It is vertically positioned and guided through the guide frame and the side frames on both sides of the bogie to ensure the correct position of the wheelset assembly in the bogie, thereby converting the rotation of the wheel into the linear motion of the car body along the track, and transferring the load of the car body to the axle and wheel, and finally to the track.

[0003] like Figure 1 and Figure 2 As shown, the load-bearing saddle commonly used on the market currently includes 4 end faces and 4 chamfers. There are 2 groups of symmetrical end faces and chamfers, and each group has 2 end faces and 2 chamfers. Among them, 2 end faces and 2 chamfers are located at one end of the load-bearing saddle, and the remaining 2 end faces and 2 chamfers are located at the other end of the load-bearing saddle. In addition, 1 end face and 1 chamfer are close to each other, but the end face blocks the chamfer, that is, the chamfer and the end face to be milled are not on the same horizontal plane. At present, the tool of an ordinary vertical milling machine generally only moves left and right. Although the ordinary vertical milling machine can be modified through existing technical means so that the tool can also move up and down, the end face is located above the chamfer and blocks the chamfer. In this way, when milling the chamfer, the end face will be damaged, that is, the current ordinary vertical milling machine cannot directly mill the end face and chamfer.

[0004] In the prior art, there is a special double-sided milling lathe, which can be used to mill the two end faces of one end of the bearing saddle. However, the special double-sided milling lathe needs to disassemble the bearing saddle and then re-clamp the other end of the bearing saddle before milling the end face of the other end of the bearing saddle. This is equivalent to the current special double-sided milling lathe need to be clamped twice to complete the milling of the end face of the bearing saddle. This not only requires the purchase of a special double-sided milling lathe for milling the end face, which is costly, but also requires two clampings even if a special double-sided milling lathe is used to mill the end face, resulting in low production efficiency. Secondly, since the end face and the chamfer are not on the same horizontal plane, and the end face blocks the chamfer, milling the end face of the bearing saddle and milling the chamfer of the bearing saddle are two different processes. After the end face is milled using a special double-sided milling lathe, the bearing saddle is transferred and installed on a vertical milling machine, and the bearing saddle chamfering cutter or alloy milling cutter is used to mill the bearing saddle chamfer, and the two processes generally require different technicians to be responsible for milling. This not only takes a long time, but also has high labor costs.

[0005] If the chamfer and the end face are milled together, that is, the two processes are combined into one process, not only a special CNC milling machine is required, but also a new and special tool needs to be designed to cooperate with the CNC milling machine to mill the chamfer and the end face at the same time. In this way, the purchase cost of the CNC milling machine is high, and a new tool needs to be designed for use with it, which has high design and maintenance costs and takes a long time to design. Summary of the invention

[0006] In order to improve processing efficiency and reduce production costs, a first solution is to provide a tooling for multi-faceted milling of a saddle.

[0007] A tooling for multi-faceted milling of a bearing saddle comprises a bearing saddle, which is installed on a vertical milling machine, and also comprises a main mechanism, a rotating mechanism and a locking mechanism; the main mechanism comprises a rotating seat, a left supporting seat and a right supporting seat, and the left rotating seat is located between the left supporting seat and the right supporting seat; the rotating seat comprises a left turntable, a right turntable and a rotating frame; the left turntable is close to the left supporting seat, the right turntable is close to the right supporting seat, the rotating disk is located between the left turntable and the right turntable, one end of the rotating disk is fixedly connected to the left turntable, and the other end is fixedly connected to the right turntable; a plurality of bearing saddles are fixedly installed on the rotating frame; a rotating mechanism is arranged on the left supporting seat, the rotating mechanism is key-connected to the left turntable, and the rotating mechanism is used to rotate the rotating seat; a locking mechanism is arranged on the right supporting seat, the locking mechanism is connected to the right turntable, and the locking mechanism is used to position and lock the rotating seat.

[0008] Beneficial effect: Compared with the prior art, the first solution provides a tooling for multi-sided milling of a saddle. Firstly, the tooling can be directly installed on an ordinary vertical milling machine, and there is no need to use a dedicated double-sided milling lathe to mill the end face. The tooling is more comprehensive, has strong applicability, and is highly flexible, avoiding the cost of purchasing a dedicated double-sided milling lathe.

[0009] Secondly, after milling the end face, the saddle had to be transferred to an ordinary vertical milling machine to mill the saddle chamfer. The tooling can be directly installed on an ordinary vertical milling machine. The tooling can not only mill the end face directly on the vertical milling machine, saving the transfer link, but also can mill the saddle chamfer, thereby improving production efficiency.

[0010] Moreover, after the milling of the end face and the chamfering of the bearing saddle are combined into one process, only one person is needed to operate the process, which reduces labor costs;

[0011] Subsequently, a plurality of bearing saddles can be milled at one time on the tooling, which improves production efficiency compared to milling only a single bearing saddle at one time.

[0012] At the same time, even if there is existing technology that allows the use of a dedicated CNC milling machine and a new dedicated tool to cooperate in order to combine the end face and chamfer into one process and perform milling, compared to this, the design cost of the first solution is lower, and it is suitable for an ordinary vertical milling machine to complete the two processes. Moreover, new tools and CNC milling machines that are compatible with this type of CNC milling machine require special personnel to maintain, and the maintenance of dedicated tools and CNC milling machines is relatively troublesome and has high maintenance costs. The tooling provided by the first solution can be used directly on the vertical milling machine, and only daily simple maintenance of the vertical milling machine and the tooling is required, and the maintenance cost is low.

[0013] Finally, after the rotating seat is rotated by the rotating mechanism and then locked by the locking mechanism, the vertical milling machine mills the two end faces on the same side, and then the vertical milling machine mills the two chamfers on the same side and close to the milled end face after another rotation by the rotating mechanism. Subsequently, the two chamfers on the other side are milled again, and the end face on the other side is milled again after another rotation.

[0051] Embodiment 1

[0052] This embodiment provides a tooling for carrying a saddle 1 for multi-faceted milling, comprising a main body mechanism, a rotating mechanism and a locking mechanism.

[0053] like Figure 4 As shown, the main body mechanism includes two support seats and a rotating seat. The support seats include a left support seat 2 and a right support seat 3. The rotating seat includes a rotating frame 4, a left turntable 5, a right turntable 6, four support blocks, sixteen positioning blocks 18 and a pressing assembly.

[0054] Specifically, as Figure 5 and Figure 6 shown, two first through holes 41 are formed on the left and right sides of the rotating frame 4, and two support blocks are fixedly installed below each first through hole 41. The support blocks are in an inverted "U" - shaped structure, that is, the bottom end of the support block is a concave structure. Two second through holes 42 are also formed on the rotating frame 4 between the two first through holes 41. As Figure 7 shown, two groups of positioning blocks 18 are fixedly installed at the upper end of each second through hole 42. Each group of positioning blocks 18 has a total of eight. Among the four positioning blocks 18 in the same group, the other four positioning blocks 18 are located on the back of these four positioning blocks 18. One threaded support through hole 101 is also formed between the two second through holes 42. The first through holes 41 and the second through holes 42 are both centered on the threaded support through hole 101. The left end of the rotating frame 4 is fixedly connected to the left turntable 5, and its right end is fixedly connected to the right turntable 6. The pressing assembly includes two fixing bolts 12, two pressing plates 11 and a pull rod 10. The outer surface of the pull rod 10 is provided with threads, and the two ends of the pull rod 10 are respectively thread - connected to each fixing bolt 12 and each pressing plate 11. The pull rod 10 passes through the threaded support through hole 101, and the two are thread - connected. The pressing plate 11 is located between the fixing bolt 12 and the rotating frame 4.

[0055] As Figure 1 , Figure 2 and Figure 3 shown, the bearing saddle 1 is prior art. According to the description of each part of the bearing saddle 1 in the prior art, the bearing saddle 1 includes a thrust shoulder 130, a bearing saddle top surface 140, a bearing saddle bottom surface 150, an end face 110 and a chamfer 120. As Figure 8 , Fig. 9 and Fig.10 shown, two groups of bearing saddles 1 can be directly installed in this rotating frame 4. One group of bearing saddles 1 has a total of two, that is, there are a total of four bearing saddles 1. Each group of bearing saddles 1 is respectively close to the two first through holes 41. The thrust shoulder 130 of each bearing saddle 1 abuts against the adjacent two support blocks. The two bearing saddles 1 in one group of bearing saddles 1 are symmetrically arranged with the rotating frame 4 as the center of symmetry. The bearing saddle bottom surface 150 abuts against the same group of positioning blocks 18. Then, each pressing plate 11 rotates on the pull rod 10 and presses one group of bearing saddle top surfaces 140. The fixing bolt 12 rotates and abuts against the pressing plate 11 to further press the two bearing saddles 1 in the same group.

[0056] As Fig.11 shown, the rotating mechanism is arranged on the left support seat 2. The rotating mechanism includes a left mandrel 19, a left air cylinder 8, a rack 9 and a gear 7.

[0057] Specifically, the left turntable 5 and the left spindle 19 are connected by a key, and the left spindle 19 and the left support seat 2 are connected by rotation. The left support seat 2 is provided with a first left through hole, and the left turntable 5 is provided with a second left through hole 51. The first left through hole and the second left through hole 51 are matched and flush in structure and size. The left spindle 19 passes through the first left through hole of the left support seat 2 and the second left through hole 51 of the left turntable 5. The left spindle 19 and the left turntable 5 are connected by a key, that is, the left spindle 19 can drive the left turntable 5 to rotate, so as to drive the rotating seat to rotate. The left pneumatic cylinder 8 and the rack 9 are fixedly mounted on the bottom plate 22 of the left support seat 2, and the rack 9 is close to the side plate 21 of the left support seat 2. A gear 7 through hole is provided in the center of the gear 7, and the gear 7 through hole passes through the left spindle 19, and the gear 7 and the left spindle 19 are connected by a key. The gear 7 is located on one side of the side plate 21 of the left support seat 2, facing away from the left turntable 5. The left pneumatic cylinder 8 includes a piston rod, and the piston rod of the left pneumatic cylinder 8 is connected to one end of the rack 9. When the piston rod of the pneumatic cylinder moves up and down, the rack 9 also moves up and down, and the rack 9 is meshed with the gear 7. When the rack 9 moves up and down, the gear 7 rotates accordingly. When the gear 7 rotates, it drives the left spindle 19 to rotate, and the left spindle 19 drives the rotating seat to rotate.

[0058] Specifically, Fig.12 and Fig.13 As shown, ratchet teeth 91 are provided on the inner wall of the gear 7, and there are 8 ratchet teeth 91 in total, which are evenly distributed on the circumferential surface formed by the inner wall of the gear 7, and the angle between two adjacent ratchet teeth 91 is 45°. The ratchet teeth 91 include a first tooth surface 911 and a second tooth surface 912, and one end of the first tooth surface 911 and the second tooth surface 912 are fixedly mounted on the inner wall of the gear 7, and the other ends of the first tooth surface 911 and the second tooth surface 912 are fixedly connected to each other. The angle between the first tooth surface 911 and the second tooth surface 912 is 107.6°. A tooth groove 913 is fixedly connected between two adjacent ratchet teeth 91, and there are 8 tooth grooves 913 in total. The tooth groove 913 is located on the right side of the second tooth surface 912 of one ratchet tooth 91 and on the left side of the first tooth surface 911 of the ratchet tooth 91 adjacent thereto. The angle between the tooth groove 913 and the first tooth surface 911 is 17.6°, and the angle between the tooth groove 913 and the second tooth surface 912 is 90°.

[0059] like Fig.14 and Fig.15As shown, the left spindle 19 includes a first left-turning column 191, a second left-turning column 192, a third left-turning column 193 and a fourth left-turning column 194 from left to right. The first left-turning column 191 is connected to the second left-turning column 192, the second left-turning column 192 is connected to the third left-turning column 193, and the third left-turning column 193 is connected to the fourth left-turning column 194. The first left-turning column 191 passes through the gear 7 and matches the through hole of the gear 7. The cross-sectional area of ​​the second left-turning column 192 is larger than the first left-turning column 191 and the third left-turning column 193. The second left-turning column 192 and the first left through hole on the left support seat 2 are clearance-matched. A left key groove 196 is provided on the third left-turning column 193, and a key is provided on the outer surface of the first left through hole, and the left key groove 196 is connected to the key. The third left-turning column 193 is fixedly connected to the second left through hole 51 on the left turntable 5. The cross-sectional area of ​​the fourth left-turning column 194 is larger than the second left-turning column 192. The fourth left-turn column 194 abuts against the exterior of the left turntable 5 .

[0060] The first left turning column 191 is provided with a first left groove, in which a spring is installed. The spring is located in the first left groove and may not be exposed in the first left groove. The top of the spring is movably connected with a pawl 195, and the pawl 195 is exposed in the first left groove. The pawl 195 is bounced up by the spring and clamped on the ratchet 91. Specifically, the pawl 195 is clamped between the first tooth surface 911 of one ratchet 91 and the second tooth surface 912 of another adjacent ratchet 91.

[0061] The left motor drives the rack 9 to move up and down, and rotates the gear 7 through the rack 9. At this time, under the action of the movement of the gear 7 and the spring force, the pawl 195 contacts the ratchet 91, moves from the first tooth surface 911 of the pawl 195 to the second tooth surface 912, and then engages with the tooth groove 913. This engagement means that the pawl 195 can only continue to move in one direction, but cannot move in two opposite directions. The angle between the tooth groove 913 and the second tooth surface 912 is large, and it is difficult for the pawl 195 to return to the second tooth surface 912. The angle between the tooth groove 913 and the first tooth surface 911 is small, and the movement direction of the pawl 195 can only be from the tooth groove 913 to the first tooth surface 911. Even under the action of the rack 9, the pawl 195 cannot directly return from the second tooth surface 912, that is, under the action of the pawl 195, the gear 7 can only rotate in one direction. Specifically, the pawl 195 can only move from the tooth groove 913, through the first tooth surface 911 and then to the second tooth surface 912, but cannot move from the tooth groove 913 to the second tooth surface 912. Therefore, the rotating seat can only rotate in one direction.

[0062] The rotating mechanism is used to rotate the rotating seat 360°, and the angle between each ratchet 91 is 45°. Under the action of the pawl 195, each time the rack 9 moves up and down, the gear 7 can rotate 45° in one rotation, that is, each rotation will rotate the rotating seat 45°. Every time the rotating seat rotates 45°, a milling operation is performed. The angle setting of the first tooth surface 911, the second tooth surface 912 and the tooth groove 913, and the spring driving the pawl 195 to move on the ratchet 91, can not only satisfy that the gear 7 can rotate 45° in one rotation, but also that the gear 7 can only move in one direction. In this way, after rotating from 0° to 360°, rotating 8 times, and milling 8 times, the entire milling process is completed. In this way, the bearing saddle 1 installed on the rotating seat can directly complete the complete milling process of the end face 110 of the bearing saddle 1 and the chamfer 120 of the bearing saddle 1 on an ordinary vertical milling machine.

[0063] like Figure 4 As shown, the locking mechanism is used to lock the rotating seat. The locking mechanism includes a right spindle 16, a right pneumatic cylinder 13, a pressure rod 14 and a positioning pin 15.

The dovetail grooves 23 are used to fix the tooling and the workbench of the vertical milling machine, that is, to fix the tooling on the workbench of the vertical milling machine.

[0065] like Fig.18 and Fig.19 As shown, the pressure rod 14 includes a first rod body 141 and a first clamping column 142, and the first rod body 141 and the first clamping column 142 are fixedly connected. A rod body through hole 144 is provided on the first rod body 141, and the rod body through hole 144 is used for the piston rod of the right cylinder to pass through the rod body through hole 144 and be fixedly connected with the rod body through hole 144. When the piston rod moves left and right, it can drive the first rod body 141 to move left and right. A pin shaft through hole 143 is also provided on the first rod body 141, which is used to be connected to the positioning pin 15 by a pin shaft. The first rod body 141 is located below the first clamping column 142, and the first rod body 141 abuts against the bottom plate 22 of the right support seat 3. The first rod body 141 and the positioning pin 15 are connected by a pin shaft. As shown Fig. 20 As shown, the right mandrel 16 includes, from left to right, a second clamping column 161, a first sliding column 162, a second sliding column 163 and a clamping bolt 164. The second clamping column 161 is fixedly connected to one end of the first sliding column 162, and the other end of the first sliding column 162 is fixedly connected to the second sliding column 163. A sliding through hole 165 is provided on the second sliding column 163, and the first rod body 141 passes through the sliding through hole 165, and the first rod body 141 and the sliding through hole 165 are slidably connected. The first clamping column 142 is located above the sliding through hole 165, and the cross-sectional area of ​​the first clamping column 142 is larger than the cross-sectional area of ​​the sliding through hole 165 and the first rod body 141. A threaded clamping through hole is provided at the right end of the second sliding column 163, and the threaded clamping through hole is far away from the first sliding column 162. The clamping bolt 164 is threadedly connected to the threaded clamping through hole. The first sliding post 162 is in clearance fit with the first right through hole 62 and the second right through hole 31. The second pressing post 161 is located outside the right turntable 6. The cross-sectional area of ​​the second pressing post 161 is larger than the cross-sectional area of ​​the first right through hole 62. The second sliding post 163 faces away from the right support seat 3. The cross-sectional area of ​​the second sliding post 163 is larger than the cross-sectional area of ​​the second right through hole 31.

[0066] like Fig.21 As shown, the positioning pin 15 includes a first positioning column 151 and a second positioning column 152 from left to right. The first positioning column 151 and the second positioning column 152 are fixedly connected. The cross-sectional area of ​​the first positioning column 151 is larger than the cross-sectional area of ​​the second positioning column 152, the second positioning column 152 passes through the first positioning through hole 32, and the second positioning column 152 and the first positioning through hole 32 are loosely matched.

When the second positioning column 152 is inserted into the first positioning hole 61 to a certain depth, the first positioning column 151 presses against the outer surface of the right support seat 3.

[0067] Specifically, Fig. 22 As shown, when the first spindle drives the rotating seat to rotate, the right pneumatic cylinder 13 opens and pushes the pressure rod 14 to move toward the right support seat 3. At this time, the middle part of the pressure rod 14 is connected to the positioning pin 15 by a pin shaft, and the positioning pin 15 moves to the left, passes through the first positioning through hole 32, and then is inserted into the first positioning hole 61 to play a positioning role. Secondly, when the second positioning column 152 is inserted into the first positioning hole 61, the first positioning column 151 will also move until it is pressed against the outer wall of the right support seat 3. At this time, the middle part of the pressure rod 14 is equivalent to the fulcrum of the lever. According to the principle of lever, the lower part of the pressure rod 14 gradually approaches the right support seat 3 under the drive of the right pneumatic cylinder 13, and the upper part of the pressure rod 14 slides in the sliding through hole 165 and gradually moves away from the right support seat 3, and then presses against the clamping bolt 164 and gives the clamping bolt 164 a rightward thrust. The thrust is opposite to the force of the pneumatic cylinder driving the pressure rod 14, thereby driving the right core shaft 16 to move to the right, and the second clamping column 161 of the right core shaft 16 gradually approaches and presses against the right turntable 6, thereby locking the rotating seat.

[0068] like Fig. 22 As shown, after locking the rotating seat, start the vertical milling machine to mill the chamfer 120 plane of the bearing saddle 1. After the processing is completed, reset the right pneumatic cylinder 13, and the right pneumatic cylinder 13 pushes the pressure rod 14 to move to the right, away from the right support seat 3. At this time, the positioning pin 15 will be driven to move to the right through the pin shaft to first make the second positioning column 152 of the positioning pin 15 leave the first positioning hole 61. At this time, the positioning pin 15 is the lever fulcrum, that is, the middle part of the pressure rod 14 is the lever fulcrum. According to the lever principle, the lower part of the pressure rod 14 moves to the right, and the upper part of the pressure rod 14 moves to the left, leaving the clamping bolt 164, and the second clamping column 161 of the right spindle 16 also leaves the right turntable 6, which is equivalent to the right spindle 16 loosening the rotating table, and then the right spindle 16 is used as a fulcrum to drive the positioning pin 15 to leave the first positioning hole 61, completing the processing of the end face 110 of the bearing saddle 1.

[0069] The beneficial effects of this embodiment

[0070] Compared with the prior art, the end face 110 and the chamfer 120 of the bearing saddle 1 can only be milled through two processes respectively. If the two processes are combined, a dedicated CNC milling machine equipped with a newly designed dedicated tool is required to complete the milling.

[0071] This embodiment is different. First, the tooling provided in this embodiment installs the bearing saddle 1 on the rotating frame 4, and uses the rotating mechanism and the locking mechanism to rotate the rotating frame 4 by 45° each time. When rotating by 45°, the end face 110 is milled. After the milling is completed at 45°, the adjacent chamfer 120 is milled at 90° to complete the milling of two bearing saddles 1 located on the same plane. The milling of the end faces 110 and chamfers 120 of two bearing saddles 1 on another plane is completed at 90°-180°. In this way, the two processes of milling the end face 110 and the chamfer 120 can be directly completed on an ordinary vertical milling machine.

[0072] Secondly, the first through hole 41 and the second through hole 42 are provided to facilitate the workers to observe the milling condition of the bearing saddle 1 in all directions, and to greatly reduce the weight of the rotating frame 4, so that the rotating frame 4 can rotate smoothly. The milling space of an ordinary vertical milling machine is limited, and multiple bearing saddles 1 can be arranged on the rotating seat for milling together, which improves production efficiency. In addition, the support block supports the thrust shoulder 130, the positioning block 18 positions the bottom surface 150 of the bearing saddle, and the clamping assembly clamps the top surface 140 of the bearing saddle, and two groups of four bearing saddles 1 are fixed simultaneously from three directions, which not only plays the role of firmly pressing multiple bearing saddles 1 against the rotating seat at the same time, but also fixes the bearing saddle 1 in multiple directions without interfering with the milling operation of the end face 110 of the bearing saddle 1 and the chamfer 120 of the bearing saddle 1. It is also possible to directly fix a group of two bearing saddles 1 at a time through the pressing plate 11, and this fixing and installation method is faster and has high installation efficiency. At the same time, the pressing plate 11 can rotate freely on the pull rod 10, and the pull rod 10 can also rotate, so it can be suitable for fixing the common load saddles 1 of various shapes on the market, that is, the load saddles 1 of different heights can be pressed by the rotation of the pressing plate 11. Next, one pressing plate 11 presses a group of load saddles 1, and the shapes of this group of load saddles 1 are the same, and another pressing plate 11 presses another group of load saddles 1, and the shapes of this group of load saddles 1 and the other group of load saddles 1 can be different, that is, the heights of the load saddles 1 are different, so the tooling of this embodiment can also mill load saddles 1 of different shapes at the same time. Finally, a group of load saddles 1 are fixedly installed on the left and right sides of the rotating frame 4 respectively, and it does not affect the workers' all-round observation of the load saddle 1 when milling the load saddle 1, so that the milling space of the ordinary vertical milling machine can be maximized, so that the tooling can simultaneously mill multiple load saddles 1 in the limited space of the vertical milling machine.

[0073] Furthermore, the angle between each ratchet tooth 91 is 45°, and the angle between the first tooth surface 911, the second tooth surface 912 and the tooth groove 913 makes the pawl 195 only move in one direction, and after each movement, the pawl 195 is clamped on the next tooth groove 913, and the rotating frame 4 will rotate exactly 45°. After rotating 45°, the locking mechanism is locked and locked. Specifically, the angle of each first positioning hole 61 is 45°, and the positioning pin 15 can be inserted into the first positioning hole 61 and positioned, and then the right spindle 16 can also clamp the right turntable 6 immediately to achieve the locking effect. In this way, not only can the vertical milling machine stably and with high quality mill the end face 110 or chamfer 120 each time the tooling is rotated 45°, but also when the right cylinder moves, the locating pin 15 moves, and under the action of the lever principle, the right spindle 16 also moves accordingly, thus integrating the positioning and locking. There is no need to perform other operations for positioning and locking separately, and only the right pneumatic cylinder 13 needs to be operated. In this way, the rotating frame 4 can be efficiently locked or unlocked.

[0074] Embodiment 2

[0075] This embodiment provides a method for using a tool for carrying multi-faceted milling of a saddle 1, which is applied to a tool for carrying multi-faceted milling of a saddle 1 described in the above embodiment, and includes the following steps:

[0076] S1, respectively installing four bearing saddles 1 on a tooling for multi-faceted milling of the bearing saddle 1.

[0077] Specifically, in one embodiment, two load saddles 1 of the same size can be installed on the same side of the rotating frame 4, or two load saddles 1 of the same size can be installed on the other side of the rotating frame 4, wherein the sizes of the load saddles 1 on both sides of the rotating frame 4 can be different. The thrust shoulder 130 of the load saddle 1 is positioned by the positioning block 18, the support block supports the bottom surface 150 of the load saddle, and the rotating pressing plate 11 presses the top surface 140 of the load saddle, so that the end faces 110 and chamfers 120 on different sides of the load saddle 1 can be exposed, and then the end faces 110 and chamfers 120 can be milled.

[0078] S2, a tooling for carrying saddle 1 for multi-faceted milling is fixedly installed on the vertical milling machine, at this time it is 0°.

[0079] Specifically, 0° means that at this time, the rotating frame 4 is parallel to the worktable of the vertical milling machine.

[0080] S3, the locking mechanism is locked, and the vertical milling machine is started to mill the end surface 110 of the target bearing saddle 1.

[0081] Specifically, the right pneumatic cylinder 13 operates to drive the positioning pin 15 to be inserted into the first positioning hole 61 , and the second clamping column 161 presses against the right rotating seat, thereby locking the rotating frame 4 .

[0082] S4, release the locking mechanism and rotate 45° through the rotating mechanism.

[0083] Specifically, the right pneumatic cylinder 13 is reset, the positioning pin 15 is pulled out of the first positioning hole 61, and the second pressing column 161 does not touch the right rotating seat. The left pneumatic cylinder 8 operates, the rack 9 drives the gear 7 to operate, the gear 7 drives the left spindle 19 to rotate, and the left spindle 19 drives the rotating frame 4 to rotate. The pawl 195 moves from a tooth groove 913 along the first tooth surface 911 to the second tooth surface 912, and then to the next tooth groove 913, and then the left pneumatic cylinder 8 stops operating.

[0084] S5, locking the locking mechanism, starting the vertical milling machine to mill the target bearing saddle 1 chamfer 120.

[0085] Specifically, the right pneumatic cylinder 13 operates to drive the positioning pin 15 to be inserted into the first positioning hole 61, and the second clamping column 161 presses against the right rotating seat, thereby locking the rotating frame 4. Then, the adjacent chamfer 120 of the end surface 110 of the bearing saddle 1 that has been processed is milled.

[0086] S6. Similarly, process the other chamfers 120 and end faces 110 of the bearing saddle 1, as well as the chamfers 120 and end faces 110 of other unprocessed bearing saddles 1, and successively process the planes at azimuths of 45 degrees, 90 degrees, 135 degrees, 180 degrees, 225 degrees, 270 degrees, and 315 degrees to complete the milling of the end face 110 and chamfer 120 of the bearing saddle 1.

[0087] Specifically, at each different rotation angle, a separate end face 110 or chamfer 120 will be milled. In a bearing saddle 1, there are 4 end faces 110 and 4 chamfers 120, of which 2 end faces 110 are on the same plane and 2 chamfers 120 are on the same plane; the other 2 end faces 110 are on another same plane and the other 2 chamfers 120 are on another same plane. The two bearing saddles 1 on one side of the rotating seat have their axes collinear and are placed symmetrically with the pull rod 10 as the symmetry line. That is, when milling at one angle, the two end faces 110 or chamfers 120 of the two bearing saddles 1 will be milled at the same time.
