Description

Technical Field

[0001] The present application relates to the field of automobile processing equipment, and in particular to a tooling fixture for an automobile deflation valve. Background Art

[0002] The car's pressure relief valve is usually installed next to the turbine. In a turbocharged system, there are two types of car pressure relief valves: the exhaust pressure relief valve and the intake pressure relief valve. The intake pressure relief valve is used to protect the intake blades in the turbocharged system. When the throttle is closed, the intake pressure relief valve can discharge excess air from the trachea, so that the intake blades can avoid conflict with the backflow of air and thus avoid damage. The exhaust pressure relief valve can protect the engine and turbocharger. It should be noted that the turbocharged system is in a high temperature, high speed and high pressure environment for a long time. Once the internal temperature and pressure are too high, the exhaust pressure relief valve will release the internal pressure, thus protecting the turbocharger and the engine.

[0003] When producing automobile air leak valves, clamping is usually adopted. The air leak valve is usually assembled from multiple parts and has a cylindrical exterior. The sizes of air leak valves used in different automobiles are also different. During processing, corresponding tooling fixtures are usually used for clamping. As a result, different types of equipment need to be replaced when clamping different types of air pressure valves, resulting in poor adaptability of the tooling fixtures. Utility Model Content

[0010] By adopting the above technical solution, the arc-shaped extrusion groove can better fit with the cylindrical exhaust valve shell, so that the exhaust valve shell can be squeezed more tightly when the sliding extrusion rod is used to squeeze the exhaust valve shell.

[0011] Preferably, a slide groove is opened through one side of the top of the outer wall of the shell, the sliding extrusion rod is slidably connected to the slide groove, and multiple groups of sliders are provided, each group of sliders is installed one-to-one correspondingly to each sliding extrusion rod, and each group of sliders is provided with two.

At the same time, the through hole opened at the bottom allows the bottom of the air relief valve housing to be processed directly through the through hole when it is necessary to process the bottom of the air relief valve housing, thereby achieving the effect of processing the air relief valve housing at multiple positions.

[0028] The embodiment of the present application discloses a tooling fixture for an automobile deflation valve, comprising a base plate 1, a supporting leg 2 being fixed to the bottom of the base plate 1, a first supporting rod 3 being fixed to one side of one supporting leg 2 near the middle of the base plate 1, a servo motor 4 being fixed to one end of the first supporting rod 3, a rotating shaft 5 being fixed to the power output end of the servo motor 4, a turntable 6 being fixed to the top of the rotating shaft 5, a guide rail 7 being fixed to the top of the turntable 6, an outer shell 11 being fixed to the top outer wall of the base plate 1, a sliding extrusion rod 9 being movably connected through the top of the outer wall of the outer shell 11, a slider 8 being fixed to the bottom of the sliding extrusion rod 9 near the bottom of one end of the middle of the base plate 1, the slider 8 being slidably connected to the guide rail 7, a second supporting rod 14 being fixed to the middle of the second supporting rod 14, a supporting platform 15 being fixed to the middle of the second supporting rod 14, the supporting platform 15 being supported by a plurality of second supporting rods 14, and the deflation valve outer shell 16 being placed on the top of the supporting platform 15 when processing is required.

[0029] Among them, the outer wall of the rotating shaft 5 movably passes through the middle of the base plate 1, and the turntable 6 is located in the middle of the top of the base plate 1. By starting the servo motor 4, the rotating shaft 5 is driven to rotate, and then the turntable 6 is driven to rotate on the top of the base plate 1.

[0030] Among them, the number of sliding extrusion rods 9 is greater than three, and an extrusion groove 10 is opened in the middle of the opposite end of the multiple sliding extrusion rods 9. The extrusion groove 10 is arranged in an arc shape. The arc-shaped extrusion groove 10 can better fit with the cylindrical air release valve shell 16, so that the sliding extrusion rod 9 can squeeze the air release valve shell 16 more tightly.

[0031] Among them, a slide groove 12 is opened through one side of the top of the outer wall of the outer shell 11, the sliding extrusion rod 9 is slidably connected to the slide groove 12, and there are multiple groups of sliders 8, each group of sliders 8 is installed one-to-one with each sliding extrusion rod 9, and each group of sliders 8 is provided with two, and each sliding extrusion rod 9 is supported by two sliders 8, so that the lateral movement of the sliding extrusion rod 9 is better, and at the same time, a stronger lateral extrusion force can be provided.

[0032] Among them, the guide rail 7 is arranged in a horizontal spiral shape, and the central axis of the middle of the guide rail 7 is arranged in a colinear manner with the central axis of the rotating shaft 5. The guide rail 7 is driven to rotate by the turntable 6. The slider 8 is restricted by the sliding extrusion rod 9 and will not rotate with the guide rail 7. The horizontal spiral guide rail 7 enables the slider 8 to move horizontally, thereby driving multiple sliding extrusion rods 9 to move toward the middle of the base plate 1 at the same time, squeezing the middle air release valve shell 16.

[0033] Among them, a through hole 13 is opened through the bottom of the outer wall of the outer shell 11, and there are multiple through holes 13. The multiple through holes 13 are arranged equidistantly around the circumference. The through holes 13 opened at the bottom make it possible to directly pass through the through holes 13 when processing is required to process the bottom of the air relief valve shell 16.

[0035] The implementation principle of the automobile deflation valve fixture of the embodiment of the present application is as follows: a plurality of second support rods 14 support the support platform 15, and when processing is required, the deflation valve housing 16 is placed on the top of the support platform 15, and then the servo motor 4 is started to drive the rotating shaft 5 to rotate, thereby driving the turntable 6 to rotate on the top of the base plate 1, and the turntable 6 drives the guide rail 7 to rotate, and the slider 8 is restricted by the sliding extrusion rod 9 and will not rotate with the guide rail 7. The horizontal spiral guide rail 7 makes the slider 8 move horizontally, thereby driving the plurality of sliding extrusion rods 9 to move toward the middle of the base plate 1 at the same time, and the middle part of the base plate 1 is moved closer. The air release valve housing 16 is extruded, and two sliders 8 are provided in each group. Each sliding extrusion rod 9 is supported by two sliders 8, so that the lateral movement stability of the sliding extrusion rod 9 is better, and a stronger lateral extrusion force can be provided. At the same time, the arc-shaped extrusion groove 10 can better fit with the cylindrical air release valve housing 16, so that the sliding extrusion rod 9 can extrude the air release valve housing 16 more tightly. When the extrusion is completed, the servo motor 4 is stopped and processing is performed directly. When the bottom of the air release valve housing 16 needs to be processed, it can be processed directly through the through hole 13.

[0036] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
