Abstract
Description
Technical Field
[0001] This utility model relates to the field of intercooler chamber processing technology, specifically to a fixing device for processing the end face of the chamber mounting. Background Technology
[0002] For turbocharged engines, the intercooler chamber is an automotive component mounted on the turbocharger. Its function is to reduce the temperature of the high-temperature air after turbocharging, thereby reducing the engine's thermal load, increasing the intake air volume, and ultimately increasing the engine's power. During machining, the chamber requires a boring machine to flatten the mounting surface at the top of the chamber from top to bottom. Existing boring machines typically use a pressure plate to vertically press the top of the chamber to secure it, but this provides insufficient lateral stability. This allows the chamber to easily shift laterally during machining, affecting the machining accuracy and causing inconvenience. Utility Model Content
[0003] This utility model addresses the shortcomings of existing technologies by providing a fixing device for machining the mounting end face of an air chamber. It fixes the air chamber in both horizontal and vertical directions, greatly enhancing the stability of the air chamber, making it easy to use, and improving the machining quality of the mounting end face.
[0004] This utility model is achieved through the following technical solution: a fixing device for machining the end face of an air chamber, including a worktable. The worktable is provided with a clamping assembly and a pressing assembly. The clamping assembly includes a support plate fixed to the top of the worktable. Two clamping plates are slidably connected to the side wall of the support plate. The two clamping plates are arranged opposite each other and slide in the front-back direction, forming a lateral clamping space for clamping the air chamber between the two clamping plates. The support plate is also provided with a first driving mechanism for driving the two clamping plates to move towards each other. The pressing assembly includes a pressure plate and a second driving mechanism for driving the pressure plate to move up and down. A vertical clamping space for clamping the air chamber is formed between the pressure plate and the worktable.
[0005] In this solution, the first drive mechanism of the clamping assembly drives the two clamping plates to move towards each other, thereby bringing the two clamping plates closer together and clamping them on both sides of the air chamber, thus fixing the air chamber in the horizontal direction. Then, the second drive mechanism of the pressing assembly drives the pressure plate to move downward and press it against the top of the air chamber, thereby fixing the air chamber in the vertical direction. The fixing effect of the air chamber in both the horizontal and vertical directions is greatly enhanced, which greatly improves the stability of the air chamber and ensures the processing quality of the installation end face.
[0006] As an optimization, the first driving mechanism includes a main connecting rod, two auxiliary connecting rods, and a drive motor. The main connecting rod is located in the middle of the two clamping plates and extends in the front-to-back direction. One end of each of the two auxiliary connecting rods is hinged to both ends of the main connecting rod, and the other end of each auxiliary connecting rod is hinged to the two clamping plates. The drive motor is fixed to the support plate, and the output shaft of the drive motor extends in the left-to-right direction and is fixed to the center of the main connecting rod. In this optimized solution, the drive motor drives the main connecting rod to rotate around the center. Since the two auxiliary connecting rods are hinged to both ends of the main connecting rod, when the main connecting rod rotates, it drives the two auxiliary connecting rods to rotate around the center, thereby causing the two clamping plates to slide towards each other, thus clamping the two sides of the air chamber laterally.
[0007] As an optimization, two sliding rods are fixed to one end of the clamping plate near the supporting upright plate. The two sliding rods are distributed front to back. A groove extending in the front-back direction is formed on the side wall of the supporting upright plate. The ends of the two sliding rods away from the clamping plate extend into the groove and are rotatably mounted with rollers. In this optimized design, the clamping plate slides through the two sliding rods, improving the stability during sliding. The ends of the sliding rods roll within the groove via rollers, reducing friction and improving the smoothness of sliding.
[0008] As an optimization, the ends of the two clamping plates furthest from the supporting upright are bent inwards towards each other. This optimization concentrates the force when the clamping plates are in place, improving the clamping tightness.
[0009] As an optimization, the second driving mechanism is a telescopic cylinder, with the telescopic rod of the cylinder pointing upwards and fixedly connected to the pressure plate. This optimized solution uses the telescopic cylinder to drive the pressure plate to move up and down, resulting in a simple structure and convenient use.
[0010] As an optimization, the telescopic rod has external threads on its outer wall, and a through hole is provided on the pressure plate. The telescopic rod passes through the through hole and is screwed with two nuts, which are located above and below the pressure plate, respectively. In this optimized solution, the pressure plate is fixed to the telescopic rod by double nuts, which is convenient for disassembly and assembly, and facilitates adjustment of the pressure plate height.
[0011] As an optimization, the worktable is equipped with two clamping assemblies, which are respectively located at opposite ends of the air chamber, and the pressing assembly is located between the two clamping assemblies. This optimized solution uses two clamping assemblies to clamp and fix the two ends of the air chamber, further enhancing the fixation effect on the air chamber and improving stability.
[0012] The beneficial effects of this utility model are as follows: the first driving mechanism of the clamping assembly drives the two clamping plates to move towards each other, thereby bringing the two clamping plates closer to each other and clamping them on both sides of the air chamber, thus fixing the air chamber in the horizontal direction. Then, the second driving mechanism of the pressing assembly drives the pressure plate to move downward and press it on the top of the air chamber, thereby fixing the air chamber in the vertical direction. The fixing effect of the air chamber in both the horizontal and vertical directions is greatly enhanced, the stability of the air chamber is greatly improved, and the processing quality of the installation end face is guaranteed. It is also convenient to use.
[0013] The clamping assembly drives the main connecting rod to rotate around the center via a drive motor. Since the two auxiliary connecting rods are hinged at both ends of the main connecting rod, when the main connecting rod rotates, it drives the two auxiliary connecting rods to rotate around the center, thereby causing the two clamping plates to slide towards each other, achieving clamping of both sides of the clamping chamber in the lateral direction, which is convenient to use.

[0022] To clearly illustrate the technical features of this solution, the following section describes the solution through a specific implementation structure.
[0023] like Figures 1-6 As shown, a fixing device for machining the end face of an air chamber includes a worktable 1, on which a clamping assembly 2 and a pressing assembly 3 are provided. Figure 1 As shown, the workbench 1 in this embodiment is equipped with two clamping components 2, which are respectively located at opposite ends of the air chamber 4, and the pressing component 3 is located between the two clamping components 2. By clamping and fixing the two ends of the air chamber 4 with the two clamping components 2, and then pressing the top of the air chamber 4 with the pressing component 3, the fixing effect of the air chamber is greatly enhanced and the stability is improved.
[0024] The clamping assembly 2 includes a support plate 21 fixed to the top of the workbench 1. Two clamping plates 22 are slidably connected to the side wall of the support plate 21. The two clamping plates 22 are arranged opposite each other and slide in the front-back direction, forming a lateral clamping space for clamping the air chamber 4 between them. The support plate 21 is also provided with a first driving mechanism that drives the two clamping plates 22 to move towards each other. The clamping assembly 2 drives the two clamping plates 22 to move towards each other through the first driving mechanism, thereby causing the two clamping plates 22 to move closer to each other or further away from each other. When the two clamping plates 22 move closer to each other, they clamp the two sides of the end of the air chamber 4, thereby fixing the air chamber laterally.
[0025] like Figure 4 As shown, specifically, the side wall of the supporting plate 21 has a sliding groove 28 extending in the front-to-back direction. Two sliding rods 26 are fixedly connected to one end of the clamping plate 22 near the supporting plate 21. The two sliding rods 26 are distributed front-to-back, and the ends of the two sliding rods 26 away from the clamping plate 22 extend into the sliding groove 28 and are rotatably mounted with rollers 27. The clamping plate 22 slides back and forth along the sliding groove 28 via the two sliding rods 26, improving stability during sliding. The ends of the sliding rods 26 roll within the sliding groove 28 via the rollers 27, reducing friction and improving the smoothness of sliding, thus achieving a sliding connection between the clamping plate and the supporting plate.
[0026] like Figure 5 , 6 As shown, specifically, the first driving mechanism includes a main connecting rod 23, two auxiliary connecting rods 24, and a drive motor 25. The main connecting rod 23 is located in the middle of the two clamping plates 22 and extends in the front-to-back direction. One end of each of the two auxiliary connecting rods 24 is hinged to both ends of the main connecting rod 23, and the other end of each auxiliary connecting rod 24 is hinged to the two clamping plates 22. The drive motor 25 is fixed to the supporting plate 21, and the output shaft 251 of the drive motor 25 extends in the left-to-right direction and is fixed to the center of the main connecting rod 23. In this embodiment, the drive motor 24 is fixed to the side of the supporting plate 21 away from the clamping plates 22, and the output shaft 251 of the drive motor passes through the supporting plate 21 and is fixed to the main connecting rod 23. The drive motor 25 drives the main connecting rod 23 to rotate around the center. Since the two auxiliary connecting rods are hinged to both ends of the main connecting rod, when the main connecting rod 23 rotates, it drives the two auxiliary connecting rods 24 to rotate around the center, thereby causing the two clamping plates 22 to slide towards each other, thus achieving the clamping of the air chamber in the lateral direction.
[0027] Preferably, the ends of the two clamping plates 22 furthest from the supporting upright plate 21 are bent inwards towards each other. Because the ends of the clamping plates are bent, the force is concentrated at one point when the ends of the clamping plates 22 clamp the air chamber 4, thereby improving the clamping tightness.
[0028] The pressing assembly 3 includes a pressure plate 33 and a second driving mechanism that drives the pressure plate 33 to move up and down. The pressure plate 33 and the worktable 1 form a vertical clamping space for holding the air chamber 4. The second driving mechanism of the pressing assembly 3 drives the pressure plate 33 to move downward and press it against the top of the air chamber 4, thereby fixing the air chamber vertically. Combined with the lateral clamping of the two clamping assemblies 2, the fixing effect of the air chamber in both the horizontal and vertical directions is greatly enhanced, which greatly improves the stability of the air chamber and thus ensures the processing quality of the mounting end face.
[0029] like Figure 3 As shown, specifically, the second driving mechanism is a telescopic cylinder 31, with the telescopic rod 32 of the telescopic cylinder 31 facing upwards and fixedly connected to the pressure plate 33. The telescopic cylinder 31 drives the pressure plate 33 to move up and down through extension and retraction, resulting in a simple structure and convenient use.
[0030] Preferably, the telescopic rod 32 has external threads on its outer wall, and the pressure plate 33 has a through hole. The telescopic rod 32 passes through the through hole and is screwed with two nuts 34, which are located above and below the pressure plate 33, respectively. The pressure plate 33 is fixed to the telescopic rod 32 by the two nuts 34, which is convenient for disassembly and assembly and facilitates adjustment of the pressure plate height.
[0031] Working principle: When using, such as Figure 2 , 6 As shown, the air chamber 4 is placed on the worktable 1, positioned between the two clamping plates 22 of the clamping assembly 2 and below the pressure plate 33 of the pressing assembly 3. The drive motor 25 of the clamping assembly 2 is driven to rotate clockwise, causing the main connecting rod 23 to rotate counterclockwise. This rotation of the main connecting rod 23, via the auxiliary connecting rod 24, causes the two clamping plates 22 to slide closer together in the front-back direction, thus clamping the two ends of the air chamber 4 and achieving lateral fixation. Then, the telescopic cylinder 31 is driven to retract, and the telescopic rod 32 of the telescopic cylinder 31 causes the pressure plate 33 to move downwards, thus pressing the top of the air chamber 4 and achieving vertical fixation. The mounting end face of the air chamber can then be machined using a boring machine, which is convenient. After machining the mounting end face, the telescopic cylinder 31 is driven to extend, causing the pressure plate 33 to move upwards. Then, the drive motor 25 is driven to rotate counterclockwise, causing the main connecting rod 23 to rotate clockwise and reset, thus causing the two clamping plates 22 to slide away from each other, allowing the air chamber to be removed.
