Description

Technical Field

[0001] The invention belongs to the technical field of parts processing, and in particular relates to a device for processing parts of an automobile turbocharger. Background Art

[0002] The automotive turbocharger is a device used to improve engine performance. It uses the inertial force of the exhaust gas discharged by the engine to drive the turbine in the turbine chamber. The turbine in turn drives the coaxial impeller, which presses the air sent from the air filter pipe, and then compresses the intake air, so that more air is pressurized into the engine combustion chamber. This can increase the power output and efficiency of the engine.

[0003] An automobile turbocharger is composed of multiple parts, including turbine blades, turbine housing, center shaft, etc. When processing the turbine housing, due to its irregular shape, special processing tooling is required to position and clamp the turbine housing to ensure that the air hole position of the turbine housing is aligned.

[0004] For example, the patent with patent announcement number CN103465085B discloses a turbine casing exhaust hole processing device and its alignment tool. The turbine casing exhaust hole processing device slides a positioning block on the guide block so that the outer end face of the positioning block gradually approaches the positioning surface of the turbine casing exhaust hole, and continuously adjusts the position of the turbine casing so that the angle of the turbine casing exhaust hole corresponds to the positioning position of the alignment tool, thereby completing the alignment and positioning of the turbine casing. It can be seen that the above-mentioned turbine casing exhaust hole processing device needs to continuously adjust the position of the turbine casing during the alignment process, and cannot be conveniently aligned when fixed, and the operation is cumbersome, which affects the processing efficiency.

[0005] In view of the shortcomings of the above-mentioned prior art, a device for processing automobile turbocharger parts is designed to overcome the shortcomings of the prior art. The device can automatically and synchronously align the turbine shell when centering and clamping the turbine shell so that the air pipe port of the turbine shell faces a specific position. There is no need to frequently adjust the position of the turbine shell. The device is easy to operate and ensures processing efficiency. Summary of the invention

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0031] In addition, the terms "first", "second" and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. It should be noted that the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] A processing device for automotive turbocharger parts, such as Figure 1 , Figure 2 , Figure 3 and Fig.10 As shown, it includes a mounting seat 1 and a mounting plate 2 connected to the upper side of the mounting seat 1. The mounting seat 1 has mounting holes at four corners. The mounting seat 1 is horizontally or vertically mounted in a processing machine tool by using the mounting holes. A plurality of clamping columns 21 are evenly spaced and arranged along the circumferential direction on the upper side of the mounting plate 2. There are three clamping columns 21 in total. When the outer surface of the turbine shell 01 needs to be processed, the operator supports the turbine shell 01 and places the bottom surface of the turbine shell 01 on the upper side of the mounting plate 2 with the airway end of the turbine shell 01 facing upward (such as Figure 1 ), and the airway end of the turbine housing 01 is surrounded by the clamping column 21 (such as Figure 6), a plurality of clamping columns 21 are driven by a driving group 1 to move toward each other with the mounting plate 2 as the center. When the plurality of clamping columns 21 move away from each other, the turbine shell 01 is clamped from the inner side of the airway end of the turbine shell 01 to improve the stability during processing. The driving group 1 is arranged on the mounting plate 2; a dovetail groove 20 with an open opening facing forward is opened on one side of the mounting plate 2, and the dovetail groove 20 extends from the front to the back toward the center of the mounting plate 2. A dovetail block 31 is slidably inserted into the dovetail groove 20 of the mounting plate 2, and a guide bracket 32 ​​perpendicular to the dovetail groove 20 is connected to the upper side of the dovetail block 31. The dovetail block 31 is moved forward from the dovetail groove 20 The guide bracket 32 ​​on the mounting plate 2 can be removed by sliding it up and out, so as not to affect the processing of the clamped turbine shell 01. There are two left and right opposite limit clamps 33 sliding on the guide bracket 32, and a slider 34 located between the two limit clamps 33 sliding on the guide bracket 32. A two-way screw rod 35 rotates on the slider 34, and the two ends of the two-way screw rod 35 are respectively threadedly connected to the two limit clamps 33. Before the clamping column 21 clamps the turbine shell 01, the air pipe opening of the turbine shell 01 on the mounting plate 2 is first directed toward the guide bracket 32 ​​and parallel to the rear side of the guide bracket 32. In this process, The dovetail block 31 can be moved forward and backward on the dovetail groove 20 to adjust the front and rear position of the guide bracket 32, and then the two limit clamps 33 and the slider 34 are slid on the guide bracket 32, so that the left and right limit clamps 33 are respectively located on the left and right sides of the turbine shell 01 air pipe, and then the two-way screw rod 35 is rotated to make the two limit clamps 33 clamp the turbine shell 01 air pipe on the guide bracket 32, so as to realize the preliminary turbine shell 01 air pipe alignment operation. When the clamping column 21 clamps the turbine shell 01, the limit effect of the dovetail block 31 moving forward and backward along the dovetail groove 20, the limit clamps 33 and the slider 34 along The limiting effect of the left and right movement of the guide bracket 32 ​​can still make the air pipe opening of the turbine shell 01 face forward, and at the same time, the clamping column 21 completes the centering clamping of the turbine shell 01, thereby facilitating the positioning processing of the turbine shell 01. The operation is simple, and there is no need to manually use tools to repeatedly align and position. If the limiting clamping plate 33 is needed to loosen the air pipe of the turbine shell 01, the two-way screw rod 35 is rotated in the opposite direction to make the two limiting clamping plates 33 move away from each other; when the inner surface of the turbine shell 01 needs to be processed or the bottom surface of the turbine shell 01 needs to be punched, the airway end of the turbine shell 01 is placed downward on the upper side of the mounting plate 2 (such as Fig.10 ), since the top surface diameter of the turbine shell 01 is smaller than the bottom surface diameter, multiple clamping columns 21 can surround and clamp the outer side of the airway end of the turbine shell 01. In this process, the alignment operation of the air pipe opening of the turbine shell 01 is the same as above, and is performed using a guide bracket 32 ​​and two limit clamps 33, with diversified usage methods.

[0033] like Figure 3 and Figure 4As shown, it also includes a guide rod 41 slidably arranged on the dovetail block 31, and the lower end of the guide rod 41 is connected to a plate 42 embedded and slidably arranged on the lower side of the dovetail block 31, and the plate 42 is suitable for contacting the dovetail groove 20. The upper side of the plate 42 is rotatably provided with a stud 43 threadedly connected to the dovetail block 31. When a plurality of clamping columns 21 clamp the turbine shell 01, and the guide bracket 32 ​​and the limiting clamping plate 33 clamp the air pipe of the turbine shell 01, if it is necessary to continue to fix the air pipe part of the turbine shell 01 with the guide bracket 32 ​​and the limiting clamping plate 33, the stability of subsequent processing can be improved. When the support plate 42 is in contact with the dovetail groove 20, the friction force of the support plate 42 prevents the dovetail groove 20 from sliding forward, so that the guide bracket 32 ​​and the limit clamp 33 can be used to fix the trachea part of the turbine shell 01, and the guide bracket 32 ​​and the limit clamp 33 are adaptively moved when the clamping column 21 clamps the turbine shell 01, and there is no need to manually adjust the positions of the guide bracket 32 ​​and the limit clamp 33.

[0034] like Figure 3 and Figure 4 As shown, an inclined groove 40 is opened at the position of the dovetail groove 20 of the mounting plate 2, and the depth of the inclined groove 40 close to the center of the mounting plate 2 is greater than the depth of the inclined groove 40 away from the center of the mounting plate 2. The butt plate 42 is suitable for contacting the inclined groove 40 on the dovetail groove 20 of the mounting plate 2. The butt plate 42 moves downward and will be against the inclined groove 40 on the dovetail groove 20. Due to the slope of the inclined groove 40, the butt plate 42 cannot continue to move on the inclined groove 40 away from the center of the mounting plate 2. At this time, the dovetail block 31 cannot slide forward on the dovetail groove 20, so as to utilize the inclined groove 40 to increase the guide bracket 32 ​​and the limit clamp 33 to fix the trachea part of the turbine shell 01, thereby improving the stability during fixation.

[0035] like Figure 5-Figure 7As shown, the driving group 1 includes a mounting block 52 that slides on the mounting disk 2, and the lower side of the clamping column 21 is connected to the mounting block 52. The mounting disk 2 is provided with a screw rod 51 with the same number as the plurality of clamping columns 21. The axis of the screw rod 51 extends to the center of the mounting disk 2. The screw rod 51 is threadedly connected to the mounting block 52 on the plurality of clamping columns 21 one by one. The screw rod 51 is rotated so that the screw rod 51 drives the clamping column 21 to approach or move away from the center of the mounting disk 2 through the mounting block 52, so as to achieve the clamping and loosening of the turbine shell 01 on the mounting disk 2. The mounting seat 1 is connected to a mounting plate 53, and the mounting plate 54 is connected to the mounting seat 1. A rotating shaft 54 ​​that runs through the middle of the mounting plate 2 is rotatable on the mounting plate 3, and the upper end of the rotating shaft 54 ​​and the ends of the plurality of screw rods 51 that are close to each other are connected with a bevel gear 55, and the bevel gear 55 on the screw rod 51 is meshed with the bevel gear 55 on the rotating shaft 54. When the rotating shaft 54 ​​drives the bevel gear 55 thereon to rotate and meshes with the bevel gear 55 on the screw rod 51, all the screw rods 51 can be synchronously driven to rotate, so that the plurality of clamping columns 21 move toward each other. A servo motor 56 is installed on the mounting seat 1, and the output shaft of the servo motor 56 is connected to the rotating shaft 54, and the rotating shaft 54 ​​is driven to rotate by the servo motor 56.

[0036] like Figure 5 , Figure 6 and Fig.10 As shown, it also includes a plurality of clamping blocks 22 arranged evenly spaced in the circumferential direction and slidably disposed on the upper side of the mounting plate 2. There are three clamping blocks 22 in total. When the outer surface of the turbine shell 01 needs to be processed, the inner side of the airway end of the turbine shell 01 on the mounting plate 2 is surrounded by the clamping column 21, and the inner side of the bottom surface of the turbine shell 01 is surrounded by the clamping block 22 (such as Figure 6 ), the driving group 2 drives the multiple clamping blocks 22 to move toward each other with the mounting plate 2 as the center. When the multiple clamping blocks 22 move away from each other, they clamp the turbine shell 01 from the inner side of the bottom surface of the turbine shell 01. On the basis of the clamping column 21 clamping the inner side of the airway end of the turbine shell 01, the stability during processing is further improved. The driving group 2 is arranged on the mounting plate 2; when the inner surface of the turbine shell 01 needs to be processed, the airway end of the turbine shell 01 is placed downward on the upper side of the mounting plate 2 (such as Fig.10 ), and a plurality of clamping columns 21 and a plurality of clamping blocks 22 together surround and clamp the outer side of the airway end of the turbine shell 01.

[0037] like Figure 5 , Figure 6 and Figure 8As shown, the driving group 2 includes a mounting block 2 62 that slides on the mounting disk 2, and the mounting block 2 62 is connected to the lower side of the clamping block 1 22. The mounting disk 2 is provided with a screw rod 2 61 of the same number as the plurality of clamping blocks 22, and the axis of the screw rod 2 61 extends to the center of the mounting disk 2. The screw rod 2 61 is threadedly connected to the mounting blocks 2 62 on the plurality of clamping blocks 22 one by one. The screw rod 2 61 is rotated so that the screw rod 2 61 drives the clamping block 1 22 to approach or move away from the center of the mounting disk 2 through the mounting block 2 62, so as to achieve the clamping and loosening of the turbine shell 01 on the mounting disk 2. The mounting seat 1 is connected with a mounting plate 2 63, and a rotating sleeve 64 rotating around the rotating shaft 54 ​​is provided on the mounting plate 2 63. The upper end of the rotating sleeve 64 is connected to the plurality of screw rods The ends of the two 61 that are close to each other are connected with bevel gears 65. The bevel gears 65 on the screw rod 61 are meshed with the bevel gears 65 on the rotating sleeve 64. When the rotating sleeve 64 drives the bevel gears 65 thereon to rotate and mesh with the bevel gears 65 on the screw rod 61, all the screw rods 61 can be synchronously driven to rotate, so that multiple clamping blocks 22 move toward each other. A servo motor 66 is installed on the mounting seat 1. The output shaft of the servo motor 66 and the lower end of the rotating sleeve 64 are connected with a transmission gear 67. The two transmission gears 67 are meshed with each other. The servo motor 66 drives the transmission gear 67 thereon to rotate and mesh with the transmission gear 67 on the rotating sleeve 64, and the transmission gear 67 on the rotating sleeve 64 will drive the rotating sleeve 64 to rotate.

[0038] like Figure 8 and Fig. 9 As shown, it also includes a clamp block 22 slidably disposed on the clamp block 1 22. When the outer surface of the turbine shell 01 needs to be processed, the side wall of the turbine shell 01 on the mounting plate 2 is placed between the clamp block 1 22 and the clamp block 2 72 (as shown in FIG. Figure 6 ), the driving group three drives the clamp block 2 72 to move relative to the clamp block 1 22 to loosen or clamp the turbine shell 01 between the clamp block 1 22 and the clamp block 2 72. When the clamp block 1 22 clamps the inner side of the bottom surface of the turbine shell 01, the clamp block 2 72 approaches the clamp block 1 22 and clamps the outer side of the bottom surface of the turbine shell 01, thereby synchronously clamping the outer side and the inner side of the turbine shell 01, thereby realizing internal and external synchronous clamping and positioning. The driving group three is arranged on the clamp block 2 72.

[0039] like Figure 8 and Fig. 9 As shown, the driving group three includes a slide bar 71 connected to the lower side of the clamp block 2 72, and the slide bar 71 is slidably arranged on the upper part of the mounting block 2 62.

The mounting block 2 62 will drive the spur gear 75 to move and mesh with the rack 2 76 through the connecting frame 74. Since the rack 2 76 is stationary, the spur gear 75 will rotate clockwise and mesh with the rack 1 73. At this time, the rack 1 73 will gradually move the clamping block 2 72 away from Clamp block 1 22, so that clamp block 1 22 and clamp block 2 72 automatically and synchronously loosen the inner and outer sides of turbine shell 01 until spur gear 75 disengages from rack 2 76, but spur gear 75 still keeps meshing with rack 1 73, and mounting block 2 62 continues to move, which will drive clamp block 2 72 and clamp block 1 22 to move in the same direction through slide bar 71; if clamp block 1 22 and clamp block 2 72 are required to clamp turbine shell 01 at this time, the side wall of turbine shell 01 is placed between clamp block 1 22 and clamp block 2 72, and then control servo motor 2 66 to make mounting block 2 The mounting block 62 drives the clamping block 22 to move away from the center of the mounting plate 2 to approach the inner side of the turbine shell 01. The mounting block 62 also drives the spur gear 75 to move and mesh with the rack 2 76 through the connecting frame 74. Since the rack 2 76 is stationary, the spur gear 75 rotates counterclockwise and meshes with the rack 1 73. At this time, the rack 1 73 makes the clamping block 2 72 gradually approach the clamping block 22, so that the clamping block 22 and the clamping block 2 72 automatically and synchronously clamp the inner and outer sides of the turbine shell 01. It should be explained that since the outer side of the turbine shell 01 may have concave and convex The irregular shape of the turbine housing 01, therefore, when clamping, if the clamping block 1 22 has not clamped the inner side of the turbine housing 01, and the clamping block 2 72 has clamped the outer side of the turbine housing 01 in advance, the rack 1 73 cannot continue to move at this time, and the mounting block 2 62 that continues to move can still drive the spur gear 75 to mesh between the rack 1 73 and the rack 2 76 through the connecting frame 74. In this process, the spur gear 75 will rotate along the rack 1 73 and the rack 2 76, so that not only the steps of inner clamping and outer clamping are interrelated, but also they can adapt to the clamping requirements of different situations.
