Description

Technical Field

[0001] This utility model relates to the field of valve manufacturing technology, specifically to an assembly equipment for a vacuum actuator and bracket for an exhaust gas recirculation valve. Background Technology

[0002] The high-pressure exhaust gas recirculation valve (HP EGR valve) is one of the core components of the automotive engine emission control system, mainly used to reduce nitrogen oxides (NOx). x The high-pressure EGR valve acts as the "on / off controller" of the EGR (Exhaust Gas Recirculation) system, typically located upstream of the turbocharger's exhaust side (between the engine's exhaust manifold and intake manifold). It optimizes combustion by introducing a portion of the high-temperature exhaust gas into the engine's intake system, where it mixes with fresh air and participates in combustion. High-pressure EGR requires a vacuum actuator, primarily to precisely control the valve opening via vacuum drive, thus meeting the engine's dynamic adjustment needs for EGR recirculation.

[0003] In existing technologies, vacuum actuators are typically fixed in place by mounting brackets, and then the brackets are used to fix the vacuum actuators to the valves. The installation of the vacuum actuators and brackets requires press-fitting, which is a manual operation in existing technologies. This is prone to reversal and can easily lead to problems such as misalignment during press-fitting, damage to the vacuum actuator, or improper press-fitting that causes it to fall off later.

[0017] Furthermore, the bracket is provided with a fixing groove, and protruding ends are provided on both sides of the fixing groove. The vacuum actuator is provided with a mating groove that cooperates with the fixing groove. After pressing, the protruding ends are bent inward to press the vacuum actuator tightly.

[0018] The advantage of adopting the above technical solution is that the extended end is designed to be fixed to the vacuum actuator after bending, so that the vacuum actuator and the bracket do not need other connections, thus improving installation efficiency.

[0019] Furthermore, the base plate is provided with a mounting bracket, on which a rotating shaft is mounted. The pressing head is fixedly mounted to the rotating shaft, and the rotation of the rotating shaft drives the pressing head to rotate.

[0020] The advantage of adopting the above technical solution is that the rotatable clamping head can clamp the vacuum actuator, ensuring the position of the vacuum actuator is stable and guaranteeing the installation quality.

[0021] Furthermore, a motor is mounted on the side of the mounting bracket, and the output end of the motor is connected to the rotating shaft to drive the rotating shaft to rotate.

[0022] The advantage of adopting the above technical solution is that the motor is used to drive the pressing head to rotate, thereby realizing the position change of the pressing head.

[0023] Furthermore, the clamping head is provided with clamping blocks, which are symmetrically arranged and detachable, and a buffer layer is provided at its bottom.

[0024] The advantages of adopting the above technical solution are that the symmetrically arranged clamping blocks can prevent shaking, and the buffer layer can effectively prevent damage to the product and ensure the product surface is aesthetically pleasing.

[0025] Furthermore, the base plate is also provided with mounting posts, and infrared sensors are installed on the mounting posts.

Detailed Implementation

[0038] The present invention will now be described in further detail with reference to the accompanying drawings.

[0039] like Figure 1-8 As shown, this utility model discloses an assembly device for a vacuum actuator and bracket for an exhaust gas recirculation valve, comprising:

[0040] Base plate 1;

[0041] The fixing base 2 is installed on the base plate 1 and is provided with multiple positioning posts 21 for fixing the bracket 3;

[0042] The clamping assembly includes a clamping head 4 for clamping the vacuum actuator 5;

[0043] The pressing assembly includes a pressing head 6, which moves up and down to press the vacuum actuator 5 into the bracket 3.

[0044] The advantage of adopting the above technical solution is that it enables automatic pressing of the vacuum actuator 5 and the bracket 3, improves pressing efficiency, and ensures product quality and production safety.

[0045] The lower pressure head 6 has a connecting part, which is detachably connected to the protruding end 32 of the driving component 64. A support frame is provided on the base plate 1. The driving component 64 can be a pneumatic cylinder or a hydraulic cylinder. The driving component 64 is fixed on the support frame, and its protruding end 32 is connected to the lower pressure head 6, driving the lower pressure head 6 to rise and fall. A pressing part 61 is provided at the bottom of the lower pressure head 6, and a protruding part 62 is provided at the bottom of the lower pressure head 6.

[0046] Furthermore, the protrusions 62 are symmetrically arranged, and their inner surfaces are provided with inwardly inclined grooves 63. The upper side of the grooves 63 is also provided with chamfers. The grooves 63 are provided to press down the bracket 3, so that the bracket 3 and the vacuum actuator 5 are fixed together. The bottom surface of the pressing head 6 presses down on the vacuum actuator 5, so that the vacuum actuator enters the fixing groove 31. The bracket 3 is provided with a fixing groove 31, which is a square groove. The fixing groove 31 is provided with protruding ends 32 on both sides of the fixing groove 31. The protruding ends 32 are protruding feet. The vacuum actuator 5 is provided with a mating groove that mates with the fixing groove 31. During pressing, the protruding ends 32 extend into the grooves 63 and are pressed down. Due to the inclination of the grooves 63, the protruding ends 32 bend inward and clamp with the vacuum actuator 5. In this way, the vacuum actuator 5 and the bracket 3 do not need any other connection, improving the installation efficiency.

[0047] Furthermore, the fixed base 2 is provided with a receiving part 22 and a protrusion 23. The positioning column 21 is fixedly installed on the protrusion 23. The protrusion 23 is provided with a contact surface, which is a vertical surface, for positioning the bracket 3. The top of the protrusion 23 is recessed downward to avoid the vacuum actuator 5.

[0048] In some implementations, the clamping head 4 is provided with a mounting bracket 7, on which a rotating shaft is mounted. The mounting bracket 7 is provided with a bearing, and the rotating shaft is rotatably mounted. The clamping head 4 is fixedly mounted to the rotating shaft, and the rotation of the rotating shaft drives the clamping head 4 to rotate.

[0049] A motor 71 is mounted on the side of the mounting bracket 7. The motor 71 can be a servo motor. The output end of the motor 71 is connected to the rotating shaft, which drives the rotating shaft to rotate. The motor 71 is mounted on the base plate 1 and connected to the rotating shaft through a coupling. It drives the clamping head 4 to rotate and clamp the vacuum actuator 5, ensuring that the position of the vacuum actuator 5 does not wobble, thus ensuring the installation quality.

[0050] Furthermore, the clamping head 4 is provided with clamping blocks 41, which are symmetrically arranged and detachable. A buffer layer is provided at the bottom of the clamping head 41. The buffer layer can be made of rubber blocks and can be fixed by screws or adhesive. When processing different products, different clamping blocks 41 can be replaced to make the distance between the clamping blocks 41 different, which is suitable for the production of different models of products.

[0051] Furthermore, a mounting post 8 is provided on the base plate 1, and an infrared sensor 81 is provided on the mounting post 8. The mounting post 8 is locked and fixed on the base plate 1, and the infrared sensor 81 is aligned with the bracket 3 and set towards the product installation location.

[0052] In the working process, firstly, the bracket 3 is placed on the fixed base 2 by manual labor or a robotic arm. The bracket 3 is provided with a through hole for positioning that cooperates with the positioning column 21. Then, the vacuum actuator 5 is placed in the fixed groove 31. Then, the infrared sensor 81 senses the position of the vacuum actuator 5, and the pressing head 4 rotates to press the vacuum actuator. Then, the lower pressing head 6 is lowered by the switch button to press and fix the bracket 3 and the vacuum actuator 5, which facilitates subsequent installation operations, improves installation efficiency, and ensures installation quality.

[0053] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
