Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing tooling technology, and in particular to a pneumatic clamp for processing automotive engine intake manifolds. Background Technology

[0002] The intake manifold is a key component of a car engine's intake system, responsible for distributing air or air-fuel mixture to each cylinder. The intake manifold is typically a large pipe that branches into four smaller pipes that connect to the engine's throttle valve, located between the throttle valve and the engine's intake valves.

[0003] Air leakage in the intake manifold can have various negative impacts on vehicle performance and driving experience, such as: 1. decreased power performance; 2. unstable idling; 3. difficulty driving; 4. increased fuel consumption. Therefore, during manufacturing, the intake and exhaust end faces of the intake manifold need to be precisely machined to ensure the airtight connection between the intake manifold and other components.

[0004] The intake and exhaust ports of an intake manifold are not on the same end face. In existing technologies, the fine machining of the intake and exhaust port end faces of an intake manifold typically involves two processes: machining the intake port end face and machining the exhaust port end face. In practice, the intake manifold needs to be clamped twice. When these two processes are not performed in the same location, the intake manifold also needs to be transferred, resulting in relatively low machining efficiency for existing intake manifolds.

[0005] To address the problems in existing technologies, we propose a pneumatic fixture for machining automotive engine intake manifolds. Utility Model Content

[0014] The present invention will be further described in detail below with reference to the accompanying drawings. Example

[0015] like Figure 1-6As shown, this utility model discloses a pneumatic fixture for machining an automotive engine intake manifold. It includes a U-shaped base 1 with its opening facing upwards. A rotating shaft 2 is rotatably connected between two parallel sidewalls of the base 1. A support plate 3 is fixedly connected to the rotating shaft 2. The support plate 3 is equipped with positioning blocks 4, a first fixing component 5, and a second fixing component 6. The intake manifold is placed on the positioning blocks 4, and the first fixing component 5 and the second fixing component 6 are used to fix the intake manifold. Two sets of the first fixing component 5 are provided, respectively located at both ends of the support plate 3 along its length. Several sets of positioning blocks 4 are provided along the length of the support plate 3. Assuming there are N sets of positioning blocks, the second fixing component 6 is provided with (N-1) sets. The second fixing component 6 is respectively disposed between two adjacent positioning blocks 4. The base 1 has a first support component 7 and a second support component 8 on its two parallel side walls for supporting the support plate 3. The first support component 7 and the second support component 8 are respectively disposed at both ends of the width direction of the base 1. The base 1 has a groove for driving the support plate 3 with a flipping component 9. The support plate 3 is flipped 90 degrees under the drive of the flipping component 9. The intake manifold is placed on the positioning block 4 and fixed by the first fixing component 5 and the second fixing component 6. The fine machining equipment (e.g., a grinding machine) processes the air outlet end face of the intake manifold. After the air outlet end face is processed, the flipping component 9 drives the support plate 3 to flip 90 degrees. The fine machining equipment processes the air inlet end face of the intake manifold. After the air inlet end face is processed, the flipping component 9 drives the support plate 3 to reset. The first fixing component 5 and the second fixing component 6 loosen the intake manifold and remove the processed intake manifold. The above steps are repeated to process the unprocessed intake manifold in turn. Using this device, the intake and exhaust end faces of the intake manifold can be machined in a single clamping operation, saving clamping time and greatly improving machining efficiency.

[0016] The first fixing assembly 5 includes a first pressure plate 51, a first pressure rod 52, a drive rod 53, a fixing rod 54, and a first cylinder 55. The cylinder body of the first cylinder 55 is fixedly connected to the support plate 3. The fixing rod 54 is fixedly connected to the end of the cylinder body of the first cylinder 55 away from the support plate 3. One end of the first pressure rod 52 is hinged to the end of the fixing rod 54 away from the first cylinder 55, and the other end is fixedly connected to the first pressure plate 51. One end of the drive rod 53 is hinged to the piston rod of the first cylinder 55, and the other end is hinged to the first pressure rod 52. When fixing the intake manifold, the piston rod of the first cylinder 55 retracts, causing the drive rod 53 to move downward. The downward movement of the drive rod 53 causes the first pressure plate 51 (first pressure rod 52) to rotate, thereby pressing the intake manifold. When the intake manifold is released, the piston rod of the first cylinder 55 expands, causing the drive rod 53 to move upward, thereby causing the first pressure plate 51 to rotate away from the intake manifold.

[0017] The second fixing assembly 6 includes a second pressure plate 61, a second pressure rod 62, a connecting rod 63, a hinge seat 64, and a second cylinder 65. The cylinder body of the second cylinder 65 is fixedly connected to the support plate 3. The hinge seat 64 is fixedly connected to the piston rod of the second cylinder 65. One end of the second pressure rod 62 is hinged to the hinge seat 64, and the other end is fixedly connected to the second pressure plate 61. One end of the connecting rod 63 is hinged to the cylinder body of the second cylinder 65, and the other end is hinged to the second pressure rod 62. Two sets of second pressure rods 62 are hinged to the hinge seat 64, and two sets of connecting rods 63 are correspondingly provided on the cylinder body of the second cylinder 65. When fixing the intake manifold, the piston rod of the second cylinder 65 extends, pushing the hinge seat 64 to move upward, thereby pushing the second pressure plates 61 (second pressure rods 62) on both sides to rotate towards the intake manifold, pressing the intake manifold on both sides tightly. When the intake manifold is released, the piston rod of the second cylinder 65 retracts, causing the hinge seat 64 to move downward, thereby causing the second pressure plate 61 (second pressure rod 62) to rotate away from the intake manifold, thus releasing the intake manifolds on both sides.

[0018] The first support component 7 is a flat plate, with both ends fixedly connected to the two parallel inner sidewalls of the base 1. The flat plate provides support and limits the support plate 3. The second support component 8 includes a third cylinder 81 and a support rod 82. The cylinder body of the third cylinder 81 is fixedly connected to the outer sidewall of the base 1. The sidewall of the base 1 has a sliding through hole for the support rod 82. The support rod 82 is slidably connected to the sidewall of the base 1. One end of the support rod 82 protrudes from the outer sidewall of the base 1 and is fixedly connected to the piston rod of the third cylinder 81. Two sets of the second support components 8 are provided and are respectively located on the two parallel sidewalls of the base 1. When machining the outlet end face of the intake manifold, the piston rod of the third cylinder 81 retracts, and one end of the support rod 82 extends between the two parallel side walls of the base 1, supporting the lower end face of the support plate 3; when machining the inlet end face of the intake manifold, the piston rod of the third cylinder 81 extends, driving the support rod 82 to move away from each other, and then the flipping assembly 9 drives the support plate 3 to flip.

[0019] The flipping assembly 9 includes a drive motor 91, a drive gear 92, a driven gear 93, and a limiting block 94. The limiting block 94 is fixedly connected to the bottom wall of the base 1, limiting the rotation of the support plate 3. The drive motor 91 is fixedly connected to the upper end face of the limiting block 94. The drive gear 92 is fixedly connected to the output shaft of the drive motor 91, and the driven gear 93 is fixedly connected to the rotating shaft 2, meshing with the driven gear 93. When the support plate 3 is flipped, the drive motor 91 drives the drive gear 92 to rotate, and the driven gear 93 rotates under the drive of the drive gear 92, thereby causing the support plate 3 to flip. After the intake port end face of the intake manifold is machined, the drive motor 91 rotates in the opposite direction, driving the support plate 3 to reset.

[0020] In this embodiment, the movements of the cylinder and the motor are both controlled by the controller of the precision machining equipment.

[0021] In the accompanying drawings of this embodiment, three sets of positioning blocks are provided. The number of positioning blocks can be set according to actual production needs. When only one set of positioning blocks is provided, the second fixing component can be removed, and a first fixing component can be provided at each end of the positioning block. Alternatively, more sets of fixing blocks can be provided by adding a corresponding number of second fixing components based on the accompanying drawings of this embodiment.
