Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mechanical processing technology and relates to an intake manifold positioning and clamping device. Background Technology
[0002] In the automotive engine manufacturing process, the intake manifold, as a key component connecting the air filter and the engine cylinders, primarily functions to evenly distribute filtered air to each cylinder, playing a crucial role in improving engine performance and reducing emissions. With the development of the automotive industry, the design requirements for intake manifolds are becoming increasingly stringent. They not only need to meet basic physical properties such as strength and temperature resistance, but also require optimized hydrodynamic characteristics to improve intake efficiency.
[0003] During the manufacturing process of intake manifolds, precise positioning and clamping operations are required in processes such as welding, assembly, and inspection to ensure machining accuracy and quality stability. Positioning and clamping, as a crucial step in machining, directly affects the dimensional accuracy, shape accuracy, and surface quality of the parts. Therefore, selecting appropriate positioning and clamping methods and devices is essential for ensuring the manufacturing precision of the intake manifold.
[0004] However, due to the unique multi-pipe structure design of the intake manifold, existing ordinary clamping structures often cannot effectively adapt to its complex geometry. Traditional planar clamps cannot provide sufficient contact area to stably fix the various branch pipes of the intake manifold, resulting in uneven clamping force distribution, easy deformation or slippage during actual processing, which affects the quality and consistency of the final product. Utility Model Content
[0005] The purpose of this utility model is to provide an intake manifold positioning and clamping device, which uses a multi-axis structure that can adaptively extend and retract to position and clamp the intake manifold, ensuring sufficient clamping force while avoiding damage to the workpiece.
[0006] To solve the above technical problems, this utility model provides an intake manifold positioning and clamping device, including a positioning platform, a fixed clamping seat is provided on the positioning platform, a movable clamping seat is slidably connected to the upper end of the positioning platform and slides toward the fixed clamping seat, and a drive motor for driving the movable clamping seat to slide is installed on the positioning platform.
[0007] The fixed clamping seat has a ventilation chamber located away from the movable clamping seat, and the movable clamping seat also has a ventilation chamber located away from the fixed clamping seat. Each ventilation chamber has multiple limiting sliding holes in opposite directions. The bottom of each limiting sliding hole has a through hole that passes through the fixed clamping seat or the movable clamping seat. The inner diameter of each through hole is smaller than the inner diameter of the corresponding limiting sliding hole. Each through hole is slidably connected to a clamping shaft. The inner end of each clamping shaft is provided with a sliding shaft that is slidably connected to the corresponding limiting sliding hole. The outer sides of the fixed clamping seat and the outer sides of the movable clamping seat are connected to exhaust pipes and air injection pipes that communicate with the corresponding ventilation chambers. Each exhaust pipe is provided with a valve, and each air injection pipe is connected to a connector for communicating with a high-pressure air pump.
[0008] By adopting the above technical solution, after the intake manifold is placed between the fixed clamping seat and the movable clamping seat, the valve is opened to allow the exhaust pipe to exhaust. The drive motor drives the movable clamping seat to move towards the fixed clamping seat. During the process, the clamping shaft pushes the intake manifold. The shape of the intake manifold pushes the clamping shaft with its outer wall to retract inward. During the retraction of the clamping shaft, the air in the limiting sliding hole is squeezed by the sliding shaft and enters the air passage chamber. Then the air is discharged from the exhaust pipe. Finally, several clamping shafts adaptively clamp the intake manifold. The valve on the exhaust pipe is closed to prevent air from entering or leaving, so that the clamping shaft cannot slide freely. At this time, the intake manifold can be processed.
[0009] After the intake manifold is machined, the drive motor drives the movable clamping seat to slide in the opposite direction to release the intake manifold. After the intake manifold is removed, the high-pressure air pump is started, and air is injected into the ventilation chamber through the air injection pipe. After the air pressure in the ventilation chamber increases, the air pressure pushes the sliding shaft to slide outward in the limit sliding hole, so that each clamping shaft extends outward completely. The high-pressure air pump is then turned off for the next use.
[0010] The present invention is further configured such that the upper end of the positioning platform is provided with a downward sliding groove along its length, a threaded drive shaft is rotatably connected in the sliding groove, the power output shaft of the drive motor is connected to one end of the threaded drive shaft, and the lower end of the movable clamping seat is provided with a threaded sleeve that is slidably connected to the sliding groove and threadedly connected to the threaded drive shaft.
[0011] The present invention is further configured such that one end of the positioning platform is provided with a mounting slot for mounting a drive motor.
[0012] The present invention is further configured such that the free end of each clamping shaft is rounded.
[0013] The present invention is further configured such that a limiting support net is provided in the middle of each air passage, and a gap is left between each limiting support net and the inner wall of the corresponding air passage near the corresponding exhaust pipe.
[0014] The present invention is further configured such that each valve is a solenoid valve.
[0015] Compared with the prior art, this utility model uses a fixed clamping seat and a movable clamping seat to clamp the intake manifold. The clamping shafts on the movable clamping seat can adaptively retract after contacting the outer wall of the intake manifold, according to the shape of the outer wall. Finally, several clamping shafts form a shape that fits against the outer wall of the intake manifold, achieving effective positioning and clamping of the intake manifold. This can ensure sufficient clamping force while avoiding damage to the workpiece. At the same time, air is used to limit the position of the clamping shafts, preventing them from sliding freely during clamping. After use, the clamping shafts can be reset by injecting air.

Detailed Implementation
[0022] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed explanation of the intake manifold positioning and clamping device proposed in this utility model. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model. The same or similar reference numerals in the drawings represent the same or similar parts.
[0023] Example, refer to Figure 1-5An intake manifold positioning and clamping device includes a positioning platform 1. A fixed clamping seat 2 is mounted on the positioning platform 1, which is positioned vertically. A movable clamping seat 3 is slidably connected to the upper end of the positioning platform 1 and slides towards the fixed clamping seat 2. A slide groove 4 is provided on the upper end of the positioning platform 1 along its length. A threaded drive shaft 5 is rotatably connected in the slide groove 4. A threaded sleeve 6 is provided at the lower end of the movable clamping seat 3, which is slidably connected to the slide groove 4 and threadedly connected to the threaded drive shaft 5. The positioning platform 1 has an installation groove (not shown) at one end of the slide groove 4. A drive motor 7 is installed in the installation groove. The power output shaft of the drive motor 7 is connected to one end of the threaded drive shaft 5, so that the movable clamping seat 3 can be driven to slide by the drive motor.
[0024] The fixed clamping seat 2 is provided with a ventilation chamber 8 that is far away from the movable clamping seat 3. The movable clamping seat 3 is also provided with a ventilation chamber 8 that is far away from the fixed clamping seat 2. Each ventilation chamber 8 has multiple limiting sliding holes 9 in opposite directions. Each limiting sliding hole 9 has a through hole 10 at its bottom that passes through the fixed clamping seat 2 or the movable clamping seat 3. The inner diameter of each through hole 10 is smaller than the inner diameter of the corresponding limiting sliding hole 9. Each through hole 10 is slidably connected to a clamping shaft 11. The free end of each clamping shaft 11 is round. The inner end of each clamping shaft 11 is provided with a sliding shaft 12 that is slidably connected to the corresponding limiting sliding hole 9. When air is injected into the ventilation chamber 8, the air pressure can push the sliding shaft 12, causing the clamping shaft 11 to extend outward.
[0025] The outer sides of the fixed clamping seat 2 and the outer sides of the movable clamping seat 3 are connected to an exhaust pipe 13 and an air injection pipe 14, both of which communicate with the corresponding air passage 8. Each exhaust pipe 13 is equipped with a valve 15, which is a solenoid valve. Each air injection pipe 14 is connected to a connector 16 for communication with a high-pressure air pump. A limiting support net 17 is provided in the middle of each air passage 8. Each limiting support net 17 has a gap between itself and the inner wall of the corresponding air passage 8 near the corresponding exhaust pipe 13 to prevent the sliding shaft 12 from directly contacting the inner wall of the air passage, which would prevent the air injection from pushing the clamping shaft 11 out through air pressure.
[0026] Working principle: After the intake manifold is placed between the fixed clamping seat 2 and the movable clamping seat 3, the valve 15 is opened to allow the exhaust pipe 13 to exhaust. The drive motor 7 drives the threaded drive shaft 5 to rotate, which drives the movable clamping seat 3 to move towards the fixed clamping seat 2 through the threaded sliding sleeve 6. During the process, the clamping shaft 11 pushes the intake manifold. The shape of the intake manifold pushes the clamping shaft 11 on its outer wall to retract inward. During the retraction of the clamping shaft 11, the air in the limiting sliding hole 9 is squeezed by the sliding shaft 12 and enters the air passage chamber 8, and then the air is discharged from the exhaust pipe 13. Finally, the clamping shafts 11 adaptively clamp the intake manifold, and the valve 15 on the exhaust pipe 13 is closed to prevent air from entering or leaving, so that the clamping shafts 11 cannot slide freely. At this time, the intake manifold can be processed.
[0027] After the intake manifold is processed, the drive motor 7 drives the movable clamping seat 3 to slide in the opposite direction to release the intake manifold. After the intake manifold is removed, the high-pressure air pump is started, and air is injected into the air passage chamber 8 through the air injection pipe 14. After the air pressure in the air passage chamber 8 increases, the air pressure pushes the sliding shaft 12 to slide outward in the limiting sliding hole 9, so that each clamping shaft 11 extends outward completely. The high-pressure air pump is then turned off for the next use.
[0028] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
[0029] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
