Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a device for machining connection holes in an intake manifold. Background Technology

[0002] The intake manifold is one of the core components of a car engine's intake system. Simply put, it is a pipe assembly that "distributes" air or fuel mixture to each cylinder of the engine. One end of it is connected to the throttle valve, and the other end is divided into multiple branches corresponding to each cylinder of the engine. Its function is to deliver air evenly and stably to each cylinder, ensuring that the intake efficiency of each cylinder of the engine is consistent, which in turn affects the smoothness of power output.

[0003] With the diversification of engine models, the shape of intake manifold branch pipe openings is no longer limited to the traditional circle. They also adopt irregular shapes such as oblong holes to adapt to the assembly space. However, the support components are mostly standardized circular structures, which have poor contour fit with the oblong hole openings. During the processing, uneven local stress on the pipe openings can easily occur, causing problems such as deformation and vibration. At the same time, the spacing between different intake manifold branch pipe openings varies, while the spacing of the support structure is fixed, which can only match the spacing of a single specification of intake manifold branch pipe. When dealing with different engine models, the support components need to be replaced, which increases the equipment investment cost. Utility Model Content

[0028] The following drawings will disclose several embodiments of this utility model. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0029] Please see Figure 1-8 The present invention provides a device for processing connection holes for intake manifolds, comprising a base plate 1, a lifting auxiliary support device 2, and a fixing plate 3. The lifting auxiliary support device 2 and the fixing plate 3 are respectively fixed on the left and right sides of the top of the base plate 1. Support components 6 are uniformly fixedly installed on the fixing plate 3. Elongated holes 4 are symmetrically opened in the inner cavity of the fixing plate 3 above and below the support components 6.

[0030] The intake manifold branch pipe opening is fitted onto the support assembly 6, which provides support and fixation. The drill rod passes through the elongated hole 4 and then performs drilling. The lifting auxiliary support device 2 mainly supports the main pipeline of the intake manifold to ensure the overall stability of the intake manifold. It is designed as a lifting structure and can be applied to different intake manifolds.

[0031] The support assembly 6 includes a fine-tuning block 601, a pressure block 602, and a support block 603. The fine-tuning block 601 is fixedly mounted on the fixed plate 3. The right end of the pressure block 602 is fixedly connected to the fine-tuning block 601. The right end of the support block 603 is fixedly connected to the pressure block 602. The inner cavity of the pressure block 602 is provided with a pressure component. The support block 603 has a through hole 610. A center plate 611 is fixedly installed in the middle of the through hole 610. The center plate 611 and the left end of the pressure block 602 both have liquid guiding holes 618, and the two liquid guiding holes 618 are connected. Piston structures 612 are fixedly installed on both sides of the center plate 611. The input end of the piston structure 612 is connected to the liquid guiding hole 618 in the center plate 611. The output end of the piston structure 612 is fixedly connected to a cover plate 613. A support plate 614 is assembled at the end of the cover plate 613.

[0032] like Figure 4 As shown, the support block 603 has a through hole 610, and a center plate 611 is installed in the center of the through hole 610. A liquid guiding hole 618 is provided in the center plate 611. Figure 3 It can be seen that a liquid guiding hole 618 is also provided at the left end of the pressure block 602, and the two liquid guiding holes 618 are connected. Figure 4 Liquid guiding hole 618 and Figure 5 The piston structure 612 in the middle is connected.

[0033] The pressure assembly inside the pressure block 602 includes a hydraulic cylinder 607 and a sealing partition 608. Both the hydraulic cylinder 607 and the sealing partition 608 are fixedly disposed in the inner cavity of the pressure block 602. The output end of the hydraulic cylinder 607 extends through to the left side of the sealing partition 608 and is fixedly fitted with a push plate 609. The space inside the pressure block 602 located to the left of the push plate 609 is filled with magnetorheological fluid.

[0034] like Figure 3 As shown, the pressure block 602 is a piston structure, powered by a hydraulic cylinder 607, which pushes the push plate 609 to move. The internal cavity of the pressure block 602, located to the left of the push plate 609, is filled with magnetorheological fluid. This fluid is liquid when there is no surrounding magnetic field, but solid when a magnetic field is present and reaches a certain strength. When the hydraulic cylinder 607 moves the push plate 609 to the left, it pushes the magnetorheological fluid into the piston structure 612, which in turn pushes the cover plate 613 outward, pushing out the support plate 614 until it contacts the inner wall of the intake manifold. Due to the properties of the magnetorheological fluid, it cannot come into contact with air. Therefore, sealing structures are provided between the push plate 609 and the inner cavity of the pressure block 602, between the support block 603 and the pressure block 602, between the sealing partition 608 and the inner cavity of the pressure block 602, and on the output shaft of the hydraulic cylinder 607.

[0035] The support plate 614 is made of elastic metal material, which can be bent or stretched. The outer surface of the support plate 614 is provided with friction texture, which can increase the friction with the inner wall of the intake manifold opening and improve the support and limiting effect.

[0036] The upper and lower side walls of the cover plate 613 and the upper and lower ends of the inner wall of the support plate 614 are each fixed with corresponding fixing blocks 615, and hydraulic cylinders 616 are hinged between the corresponding fixing blocks 615.

[0037] like Figure 5 The hydraulic cylinder 616 shown is hinged at both ends to the fixed block 615. After the support plate 614 contacts the inner wall of the intake manifold port, hydraulic oil is injected into the hydraulic cylinder 616 to extend its output end and allow the support plate 614 to unfold, so that it can better fit the inner wall of the intake manifold port and improve the support effect. The hydraulic oil line is connected from the outside of the fixed plate 3. A reserved groove is set on the outside of the fine adjustment block 601 and the pressure block 602. After passing through the reserved groove, the hydraulic oil line passes through the micro-channel reserved in the inner wall of the through hole 610 of the support block 603 and finally extends to the hydraulic cylinder 616 at the hinge of the cover plate 613 and the support plate 614. A baffle plate can be set outside the reserved groove to prevent drill chips from damaging the hydraulic oil line during drilling.

[0038] Magnetic force application plates 5 are fixedly installed on both the front and rear sides of the fixed plate 3, and electromagnets are installed on the inner surfaces of the two magnetic force application plates 5, with opposite magnetic poles on the opposing surfaces of the two electromagnets.

[0039] After the support plate 614 is unfolded, the electromagnet is energized to generate a magnetic field that fixes the magnetorheological fluid, thereby stabilizing and securing the cover plate 613 and further improving the stability of the support plate 614.

[0040] The support plate 614 has a threaded hole 617 on its inner side, and the cover plate 613 has a threaded block that matches the threaded hole 617 fixed on its outer side. The two are fixed by threaded connection.

[0041] Each support component 6 contains three fine-tuning blocks 601. The inner cavity of each fine-tuning block 601 has a slot 604, and the two sides of the slot 604 have sliding grooves 605. Adjacent fine-tuning blocks 601 are fixedly provided with sliders 606 that are adapted to the slots 604 and sliding grooves 605, and the sliders 606 are movably inserted into the slots 604 and sliding grooves 605.

[0042] Between two adjacent fine-tuning blocks 601, the slider 606 of the former is inserted into the slot 604 and the groove 605, which can make lateral fine-tuning, thus realizing lateral movement within a certain range. This movement is suitable for intake manifolds with different branch pipe spacing.

[0043] The rear fine-tuning block 601 does not have a slider 606 and is fixedly installed on the fixed plate 3, while the front fine-tuning block 601 does not have a slot 604 and a groove 605 and is fixedly installed on the pressure block 602.

[0044] The leftmost fine-tuning block 601 is a cylindrical block, and none of them have slots 604, grooves 605 and sliders 606.

[0045] The leftmost fine adjustment block 601 serves as the reference, while the other three sets of fine adjustment blocks 601 are equipped with fine adjustment structures.

[0046] When using this device for machining connection holes in an intake manifold: the position of the support block 603 is adjusted by the fine-tuning block 601 according to the spacing of the intake manifold branch pipes. After the support blocks 603 are inserted into the intake manifold branch pipe openings, the push plate 609 pushes the magnetorheological fluid into the piston structure 612 to push out the support plate 614. After the support plate 614 contacts the inner wall of the pipe opening, the hydraulic cylinder 616 runs to unfold the support plate 614. Then, the electromagnet is energized to generate a magnetic field to fix the magnetorheological fluid, further improving the stability of the support plate 614. The lifting auxiliary support device 2 supports the main pipeline of the intake manifold. After the drill rod passes through the long hole 4, drilling can be performed.

[0047] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
