Description

Technical Field

[0002] The nozzle ring is one of the important components of the turbocharger, which is installed in the volute of the turbocharger. Figure 1 As shown, it is a schematic diagram of the structure of a nozzle ring mounting plate 1, and the mounting plate 1 is provided with evenly distributed mounting holes 2 for mounting the shift fork, referring to Figure 2 The mounting plate 2 is mounted on the supporting plate 4, and a blade 5 is mounted at the bottom of the shift fork. The upper end of the shift fork is clamped in the shift groove of the shift fork plate 3. When the shift fork plate 3 rotates, the shift fork will be driven to rotate, and the shift fork will drive the blade 5 to rotate. The gap between the blades 5 will change with the rotation of the blades 5, thereby changing the cross-section of the gas channel to control the boost. Therefore, the processing accuracy and position of the mounting hole 2 will affect the installation accuracy of the shift fork and the blade 5, thereby affecting the boost adjustment accuracy of the supercharger. The existing mounting plate processing equipment, when processing the mounting hole 2, each time a hole is processed, it is necessary to re-clamp and position for the installation of the next hole.

DETAILED DESCRIPTION

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings, and the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figure 3As shown, a nozzle ring mounting plate production equipment includes a base 6, a workbench 7, a frame 9, a processing motor 10 and a milling cutter 11. The workbench 7 is mounted on the base 6, the frame 9 is mounted on the rear side of the base 6, the processing motor 10 is mounted on the frame 9, and the milling cutter 11 is mounted on the tool holder. The tool holder is driven by the processing motor 10 through a reduction mechanism. A clamping seat 16 is fixedly mounted on the workbench 7. The clamping seat 16 is an "H"-shaped structure as a whole, with a mounting plate in the middle. Figure 3 , Figure 4 and Figure 5 A positioning turntable 14 and a dividing plate 18 are installed above the mounting plate of the clamping seat 16. The outer circumferences of the positioning turntable 14 and the dividing plate 18 are provided with mutually meshing transmission teeth, and the tooth number ratio of the positioning turntable 14 and the dividing plate 18 is equal to the number of mounting holes 2 on the mounting plate 1. When designing, the positioning turntable 14 and the dividing plate 18 are first designed according to the number of mounting holes 2. The dividing plate 18 is connected to the output shaft of the reducer 20 through the dividing shaft (the shaft on which the dividing plate 18 is installed) and the coupling, and the input shaft of the reducer 20 is connected to the motor shaft of the positioning motor 19. The upper end of the positioning turntable 14 is provided with a clamping tooth 12 and a clamping plate 13. The clamping tooth 12, the clamping plate 13 and the positioning turntable 14 are integrally formed. There is a cylindrical connecting section between the positioning turntable 14 and the clamping tooth 12, and the three are hollow, wherein the inner wall of the cavity is provided with an internal thread. The clamping tooth 12 is composed of a plurality of arc-shaped plates, and the longitudinal section of the arc-shaped plate is a wedge-shaped structure, forming a clamping structure with a cylindrical outer portion and a conical inner portion. An adjusting rod 15 is inserted in the hollow cavity, and a threaded section 24 and a locking head 23 are provided on the adjusting rod 15. The threaded section 24 cooperates with the hollow cavity through a threaded structure, and the locking head 23 is arranged on the adjusting rod 15. The bottom of the adjusting rod 15 extends to the bottom of the mounting plate of the clamping seat 16. The bottom end of the adjusting rod 15 is provided with a locking screw cap 25. By manually rotating the locking screw cap 25 and the threaded cooperation between the threaded section 24 and the inner wall of the hollow cavity, the adjusting rod 15 is driven to rotate and move up and down. When the locking head 23 moves up, the clamping teeth 12 are squeezed outward to fix the mounting disk 1 on the clamping disk 13; when the locking head 23 moves down, the clamping teeth 12 recover elastically and release the mounting disk 1. The clamping teeth 12 are required to have good elasticity and rigidity, and the outward expansion process is within the range of elastic deformation. Therefore, preferably, the clamping teeth 12 are made of spring steel, and the number of the clamping teeth 12 is three or six. Figure 6In the embodiment, the number of the clamping teeth 12 is six, which can be well clamped in the inner hole of the mounting plate 1, and the clamping force is evenly dispersed. The lower end of the positioning turntable 14 is mounted on the mounting plate of the clamping seat 16 through a tapered roller bearing 26. The lower end of the positioning turntable 14 is interference fit with the inner ring of the tapered roller bearing 26, and the outer ring of the tapered roller bearing 26 is interference fit with the clamping seat 16. Since the tapered roller bearing is split and can withstand axial and radial forces, an end roller bearing 30 and a pressure plate 17 are installed at the bottom of the mounting plate below the clamping seat 16. The pressure plate 17 is connected and fixed to the threaded hole at the bottom end of the positioning turntable 14 through a screw 31. The outer edge of the pressure plate 17 abuts against the lower end face of the end roller bearing 30 to ensure that the positioning turntable will not move upward. The positioning turntable 14 can be fixedly connected to the clamping seat 16 through a locking and fixing mechanism 22.

[0028] Specific reference Figure 7 and Figure 8 The locking and fixing mechanism 22 includes a fixing screw 45, a plug cap 27 and a plug cap 44. The clamping seat 16 is provided with a plurality of evenly distributed plug-in slots 33. The upper end of the positioning turntable 14 is provided with a plurality of evenly distributed plug-in slots 29. The upper end of the plug cap 27 is provided with a through hole for the fixing screw 45 to pass through. The diameter of the through hole is smaller than the diameter of the nut end of the fixing screw 45. The upper end of the plug cap 44 is provided with a threaded hole that cooperates with the fixing screw 45. The plug cap 27 is inserted into one of the plug-in slots 33. The plug cap 44 is inserted into one of the slots 29. The fixing screw 45 passes through the through hole on the plug cap 27 and cooperates with the threaded hole on the plug cap 44. The nut end of the fixing bolt 45 is provided with an adjusting socket 32. By inserting the steel pipe into the adjusting socket 32 ​​and rotating it, a pulling force is formed between the plug cap 1 27 and the plug cap 2 44. The pulling force value is a fixed preset value and can be controlled by a torque wrench or other tool. The component of the pulling force of the plug cap 1 27 on the plug cap 2 44 in the tangential direction of the circle where the slot 2 29 is located is set opposite to the rotation direction of the positioning turntable 14. The function of the locking and fixing mechanism 22 is to ensure that after the dividing plate 18 stops rotating, due to the gap between the meshing teeth, the clamping plate 13 will rotate slightly due to the existence of the gap, so the locking and fixing mechanism 22 must be used to ensure that the tooth surfaces on the positioning turntable 14 and the dividing plate 18 fit together.

[0029] refer to Fig. 9As shown, a positioning plate 28 is provided at the upper end of the indexing plate 18, a guide arc groove 35 is provided on the outer side of the positioning plate 28, and a positioning hole 36 is provided in the guide arc groove 35; a positioning rod 21 is installed in the slot of the clamping seat 16 on one side of the indexing plate 18, and a push block 39 and a conductive block 41 are provided on the positioning rod 21, the push block 39 is located in the moving groove 37, and the conductive block 41 is located in the conductive groove 38, and a spring 40 is sleeved on the positioning rod 21 in the moving groove 37, and the spring 40 pushes the push block 39 to drive the positioning rod 21 to abut against the guide arc groove 35, and two conductive contacts 42 are installed in the conductive groove 38, and the two conductive contacts 42 are connected in series to the positioning rod 21 In the circuit of the motor 19, when the positioning rod 21 abuts against the guide arc groove 35, the conductive block 41 contacts and conducts with the two conductive contacts 42; when the positioning rod 21 is inserted into the positioning hole 36, the conductive block 41 separates from the two conductive contacts 42, and the circuit of the positioning motor 19 is disconnected. A pull cap 43 is provided at the outer end of the positioning rod 21. The positioning rod 21 is pulled out of the positioning hole 36 by manually pulling out the pull cap 43. When pulled out, the conductive block 41 connects the two conductive contacts 42, and the positioning motor 19 is powered on and rotates, driving the positioning disk 28 to rotate one circle. The positioning rod 21 is inserted into the positioning hole 36 again, and the circuit of the positioning motor 19 is disconnected again. At this time, the next mounting hole 2 to be processed is located below the milling cutter 11.

[0030] Preferably, the top of the locking head 23 is configured to be conical, and the conical surface and the cylindrical surface of the locking head 23 are transitioned by an arc, and this design effectively reduces the wear between the locking head 23 and the inner side of the clamping tooth 12 .

[0031] Preferably, the reducer 20 is a gear reducer, and the reducer 20 is internally composed of a plurality of pairs of reduction gear pairs to ensure stable operation.

[0032] Further, such as Figure 8 As shown, mounting flanges are provided on both sides of the clamping seat 16 , and mounting grooves 34 are provided on the mounting flanges. The clamping seat 16 is fixed on the workbench 7 by bolts passing through the mounting grooves 34 and engaging with threaded holes on the workbench 7 .

[0033] Working principle: During processing, first fix the clamping seat 16 on the workbench 7, then put the set disk to be processed on the outside of the clamping teeth 12 and the clamping disk 13, turn the adjusting rod 15, move the locking head 23 upward to squeeze the clamping teeth 12 outward, and fix the mounting disk 1 on the clamping disk 13. At this time, the positioning rod 21 is inserted into the positioning hole 36, and the locking and fixing mechanism 22 fits the positioning turntable 14 with the tooth surface of the indexing disk 18, and then the crank is turned to align the mounting hole 2 to be processed with the milling cutter 11. After the alignment is completed, the mounting hole 2 is milled. After processing, the next installation is carried out. Before processing the hole 2, first loosen the locking mechanism 22, pull out the plug cap 1 27 and the plug cap 2 44, lose the restraint on the positioning turntable 14, and then manually pull out the positioning rod 21 from the positioning hole 36. When pulling out, the conductive block 41 connects the two conductive contacts 42, and the positioning motor 19 is powered on to rotate, driving the positioning disk 28 to rotate one circle. The positioning rod 21 is inserted into the positioning hole 36 again, and the circuit of the positioning motor 19 is disconnected again. At this time, the next mounting hole 2 to be processed is located below the milling cutter 11, and the locking mechanism 22 is installed again, and the tension is adjusted, and then the power is turned on again, so that the milling cutter can process the mounting hole 2. Repeat the above steps, and after all the mounting holes 2 are processed, the locking head 23 is moved down by rotating the adjusting rod 15, and the clamping teeth 12 are reset under the action of their own restoring force, and the processed mounting disk 1 is loosened, and then the next mounting disk 1 to be processed is mounted on the clamping disk 13, and the above steps are repeated to process the next workpiece.

After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
