Abstract
Description
Technical Field
[0001] This utility model relates to the field of intercooler chamber processing technology, specifically to a clamping and fixing fixture that facilitates drilling of the chamber. Background Technology
[0002] For turbocharged engines, the intercooler chamber is a 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. Figure 6 As shown, the existing air chamber 5 is usually composed of an air chamber inlet section 51, an air chamber outlet section 52, and a connecting section 53 connecting the two. The air chamber inlet section 51 and the air chamber outlet section 52 are perpendicular, and the height of the air chamber inlet section 51 is higher than the height of the air chamber outlet section 52. Furthermore, a positioning protrusion 55 and a mounting hole plate 54 are usually provided at the air inlet port of the air chamber inlet section 51 to facilitate the positioning and installation of the air chamber and the engine.
[0003] When machining the air chamber 5, bolt holes need to be drilled on the mounting plate 54. However, due to the irregularity of the air chamber structure itself, the existing device is difficult to effectively clamp and fix it. The air chamber is not fixed stably, which can easily cause the air chamber structure to shake during the drilling process, making it inconvenient for personnel to carry out drilling operations and affecting the drilling quality. Utility Model Content
[0004] This utility model addresses the shortcomings of existing technologies by providing a clamping and fixing fixture that facilitates drilling of air chambers. During drilling, the air chamber can be stably fixed, making drilling operations easier for personnel.
[0005] This utility model is achieved through the following technical solution: a clamping and fixing fixture for facilitating drilling of a gas chamber, comprising a worktable, on which a first support plate located below the gas chamber inlet section and a second support plate located below the gas chamber outlet section are fixedly mounted. The top of the first support plate has a first countersunk hole for accommodating the gas chamber inlet section, and the top of the second support plate has a second countersunk hole for accommodating the gas chamber outlet section. Two clamping mechanisms are also fixedly mounted on the worktable, each clamping mechanism having a clamping plate that moves up and down. The clamping plates of the two clamping mechanisms are respectively located above the gas chamber outlet section and above the gas chamber inlet section.
[0006] In this design, the first and second support plates are respectively positioned below the air inlet and outlet sections of the air chamber. Two vertically moving clamping plates then clamp the upper parts of the air inlet and outlet sections, applying force in the vertical direction to secure the air chamber. Furthermore, the first support plate accommodates the air inlet section through a first countersunk hole, and the second support plate accommodates the air outlet section through a second countersunk hole. These countersunk holes also limit the horizontal movement of the air chamber, enhancing its stability and making the entire air chamber more stable, thus facilitating drilling.
[0007] As an optimization, the clamping mechanism includes a telescopic cylinder and a clamping plate, with the telescopic rod of the cylinder pointing upwards and the clamping plate fixed to the telescopic rod. This optimized solution uses the extension and retraction of the telescopic cylinder to drive the clamping plate to move up and down, resulting in a simple structure and convenient use.
[0008] As an optimization, the telescopic rod has external threads on its outer wall, and the clamping plate has through holes. The telescopic rod passes through the through holes and is screwed with two nuts, which are located at the top and bottom of the clamping plate, respectively. In this optimized solution, the clamping plate is fixed to the telescopic rod by double nuts, which is convenient for disassembly and assembly, and also facilitates adjustment of the clamping plate height.
[0009] As an optimization, the first countersunk hole is a semi-circular hole. This optimized design allows the semi-circular shape to better fit the outer wall shape of the air chamber inlet section, resulting in greater stability after the air chamber inlet section is placed.
[0010] As an optimization, the second countersunk hole is a semi-circular hole. This optimized design allows the semi-circular shape to better fit the outer wall shape of the air chamber outlet section, resulting in greater stability after the air chamber outlet section is placed.
[0011] As an optimization, a groove adapted to the positioning protrusion of the air chamber is formed at the bottom of the first countersunk hole. This optimization scheme uses the groove to engage the positioning protrusion, further improving the stability of the air chamber.
[0012] As an optimization, the workbench is equipped with multiple second support plates, which are arranged along the length of the air outlet section of the air chamber. This optimized solution further improves the overall stability of the air chamber by supporting the air chamber with multiple second support plates.
[0013] The beneficial effects of this utility model are as follows: The first and second supporting plates are respectively supported below the air inlet and outlet sections of the air chamber. The first supporting plate accommodates the air inlet section through a first countersunk hole, and the second supporting plate accommodates the air outlet section through a second countersunk hole. The countersunk holes limit the horizontal movement of the air chamber, enhancing its fixation. Furthermore, two vertically moving clamping plates clamp the upper parts of the air inlet and outlet sections. The vertical cooperation of the clamping plates and supporting plates causes the air chamber to be subjected to force in the vertical direction, thereby achieving clamping and fixing of the air inlet and outlet sections, making the air chamber more stable and facilitating drilling.

[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 clamping and fixing fixture for facilitating gas chamber drilling includes a worktable 1. A first support plate 2 is fixedly mounted on the worktable 1 below the gas chamber inlet section 51, and a second support plate 3 is fixedly mounted below the gas chamber outlet section 52. Specifically, the first support plate 2 is perpendicular to the gas chamber inlet section 51, and the second support plate 3 is perpendicular to the gas chamber outlet section 52, thus supporting the gas chamber inlet section 51 and the gas chamber outlet section 52 respectively.
[0024] Preferably, the workbench 1 is provided with a plurality of second support plates 3, which are arranged along the length of the air outlet section 52 of the air chamber. In this embodiment, two second support plates 3 are arranged along the length of the air outlet section 52 of the air chamber. By supporting the air outlet section 52 of the air chamber with two second support plates 3, the overall support stability of the air chamber 5 is improved.
[0025] The first support plate 2 has a first countersunk hole 21 at its top to accommodate the air inlet section 51 of the air chamber, and the second support plate 3 has a second countersunk hole 31 at its top to accommodate the air outlet section 52 of the air chamber. During support, the air inlet section 51 of the air chamber is placed in the first countersunk hole 21, and the air outlet section 52 of the air chamber is placed in the second countersunk hole 31. The countersunk holes limit the horizontal movement of the air chamber, keeping it stable in the horizontal direction and enhancing the fixing effect on the air chamber.
[0026] In this embodiment, the first countersunk hole 21 is a semi-circular hole, and the diameter of the first countersunk hole 21 is adapted to the outer diameter of the air chamber inlet section 51. The semi-circular shape fits the outer wall shape of the air chamber inlet section better, making the air chamber inlet section more stable after placement.
[0027] In this embodiment, the second countersunk hole 31 is also a semi-circular hole, and the diameter of the second countersunk hole 31 is adapted to the outer diameter of the air outlet section 52 of the air chamber. The semi-circular shape fits the outer wall shape of the air outlet section of the air chamber better, making the air outlet section of the air chamber more stable after placement.
[0028] Two clamping mechanisms 4 are also fixed on the workbench 1. Each clamping mechanism 4 has a vertically movable clamping plate 43. The clamping plates 43 of the two clamping mechanisms 3 are located above the air chamber outlet section 52 and the air chamber inlet section 51, respectively. By clamping the upper parts of the air chamber inlet section and the air chamber outlet section respectively through the two vertically movable clamping plates 43, and with the support of the first support plate 2 and the second support plate 3, the air chamber 5 is subjected to force in the vertical direction, thereby achieving clamping and fixing of the air chamber inlet section 51 and the air chamber outlet section 52, making the air chamber more stable as a whole and facilitating drilling.
[0029] Specifically, the clamping mechanism 4 includes a telescopic cylinder 41 and a clamping plate 43. The telescopic rod 42 of the telescopic cylinder 41 faces upward, and the clamping plate 43 is fixed on the telescopic rod 42. The clamping of the air chamber 5 is achieved by the telescopic movement of the clamping plate 43 through the extension and retraction of the telescopic cylinder 41. The structure is simple and easy to use.
[0030] In this embodiment, the telescopic cylinder 41 of one clamping mechanism 4 is located on one side of the air inlet section 51 of the air chamber and is fixed to the top surface of the worktable 1. The telescopic cylinder 41 of the other clamping mechanism 4 is located on one side of the air outlet section 52 of the air chamber and is fixed to the bottom surface of the worktable 1, and its telescopic rod 42 extends through the worktable 1 to the top of the worktable.
[0031] Preferably, the telescopic rod 42 has external threads on its outer wall, and the clamping plate 43 has a through hole. The telescopic rod 42 passes through the through hole and is screwed with two nuts 44, which are located above and below the clamping plate 43, respectively. The clamping plate 43 is fixed to the telescopic rod 42 by the double nuts, which is convenient for disassembly and assembly and facilitates adjustment of the clamping plate height.
[0032] Working principle: In use, the air outlet section 52 of the air chamber is placed on the second countersunk hole 31 of the second support plate 3, and the air inlet section 51 of the air chamber is placed on the first countersunk hole 21 of the first support plate 2. The positioning protrusion 55 at the air inlet port of the air chamber 5 is inserted into the groove 22 of the first countersunk hole 21. Then, the telescopic cylinders 41 of the two clamping mechanisms 4 are driven to retract, thereby causing the two clamping plates 43 to move downward and clamp the air inlet section 51 and the air outlet section 52 of the air chamber respectively, thus clamping and fixing the air chamber 5. The operator can then perform drilling operations on the mounting plate 54 of the air chamber.
[0033] Of course, the above description is not limited to the examples above. Technical features not described in this utility model can be implemented by or using existing technology, and will not be repeated here. The above embodiments and drawings are only used to illustrate the technical solution of this utility model and are not intended to limit this utility model. This utility model has been described in detail with reference to the preferred implementation structure. Those skilled in the art should understand that any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model do not depart from the spirit of this utility model and should also fall within the protection scope of the claims of this utility model.
