Description

Technical Field

[0001] This utility model relates to the field of high-pressure common rail technology, specifically a coating tooling for high-pressure common rail parts. Background Technology

[0002] High-pressure common rail components are core components of the diesel engine fuel system, including components such as the high-pressure fuel pump, high-pressure common rail pipe, and fuel injectors.

[0003] As the "high-pressure fuel pressure stabilizing container" of the system, the high-pressure common rail pipe needs to withstand fuel pressure for a long time. Its outer wall is exposed to the high temperature, vibration and oil pollution environment of the engine compartment. Therefore, it is necessary to spray and coat its outer wall (such as epoxy resin coating) to enhance its anti-oxidation ability. When spraying and coating the high-pressure common rail pipe, a clamp is required to hold and fix it.

[0004] Traditional fixtures mostly use V-blocks and bolts to clamp and fix high-pressure common rail pipes. After clamping, the position of the high-pressure common rail pipe is fixed, which makes it inconvenient to adjust the angle during spray coating and to make it difficult to spray and coat the high-pressure common rail pipe comprehensively, resulting in a decrease in coating efficiency. Therefore, we need to propose a coating fixture for high-pressure common rail parts. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: A high-pressure common rail component coating fixture includes: a base 1 with a gantry 2 fixedly mounted on its top; a high-pressure common rail pipe body 3 with multiple sets of plugs 4 to prevent the coating from entering the inner wall of the high-pressure common rail pipe body 3; a clamping and rotating mechanism 5, located inside the gantry 2, for clamping and rotating the high-pressure common rail pipe body 3, the clamping and rotating mechanism 5 including a clamping component 51 and a rotating component 52; two sets of auxiliary support members 6, both of which are slidably mounted above the base 1, providing auxiliary support for the high-pressure common rail pipe body 3 and improving its stability; and a sliding mechanism 7, located on the base 1, for supporting the two sets of auxiliary support members 6 and driving the two sets of auxiliary support members 6 to slide. In this embodiment, the sliding mechanism 7 first moves the two sets of auxiliary support members 6 to adjust their positions. Then, the high-pressure common rail pipe body 3 to be processed is placed on the two sets of auxiliary support members 6. The two sets of auxiliary support members 6 provide unobstructed support for the high-pressure common rail pipe body 3. Then, the clamping assembly 51 clamps and fixes both ends of the high-pressure common rail pipe body 3. The rotating assembly 52 can drive the high-pressure common rail pipe body 3 to rotate, which facilitates comprehensive spray coating of the high-pressure common rail pipe body 3 and improves coating efficiency. The clamping assembly 51 includes a bidirectional lead screw 511, a first drive motor 512, two sets of clamping plates 513 and two sets of limiting blocks 514. The bidirectional lead screw 511 is rotatably installed inside the gantry frame 2. One end of the bidirectional lead screw 511 passes through the gantry frame 2 and is fixedly connected to the first drive motor 512. The two sets of clamping plates 513 are respectively threaded to the outer walls of both ends of the bidirectional lead screw 511. In this embodiment, the output end of the first drive motor 512 drives the bidirectional lead screw 511 connected to it to rotate, so that the two sets of clamping plates 513 move and adjust the distance between the two sets of clamping plates 513. Two sets of limiting grooves are provided on the inner top of the gantry frame 2. Two sets of limiting blocks 514 are slidably installed inside the two sets of limiting grooves, and the bottom of the two sets of limiting blocks 514 are fixedly connected to the two sets of clamping plates 513 respectively. In this embodiment, the two sets of limiting grooves and two sets of limiting blocks 514 can limit the two sets of clamping plates 513, so that the two sets of clamping plates 513 can move when the bidirectional lead screw 511 rotates. The rotating assembly 52 includes two sets of discs 521, a second drive motor 522, and two sets of anti-slip pads 523. The two sets of discs 521 are rotatably mounted on opposite sides of the two sets of clamping plates 513. The second drive motor 522 is fixedly mounted on one side of one set of clamping plates 513. One end of the output shaft of the second drive motor 522 passes through the clamping plate 513 and is fixedly connected to one set of discs 521. In this embodiment, when the two sets of clamping plates 513 move, they will drive the rotating component 52 to move, adjusting the distance between the two sets of discs 521. The two sets of discs 521 clamp and fix the two ends of the high-pressure common rail pipe body 3. The output shaft of the second drive motor 522 rotates, driving the disc 521 connected to it to rotate. With the cooperation of another set of discs 521 and two sets of auxiliary support members 6, the high-pressure common rail pipe body 3 can rotate, which facilitates the comprehensive spraying and coating of the high-pressure common rail pipe body 3. A bearing 10 is embedded on one side of the clamping plate 513, and one end of the disc 521 is inserted into the inner ring of the bearing 10. In this embodiment, the clamping plate 513 rotates by being inserted into the inner ring of the bearing 10; Two sets of anti-slip pads 523 are respectively glued to one end of the two sets of discs 521. The anti-slip pads 523 are made of silicone material. In this embodiment, the anti-slip pad 523 can increase the friction between the disc 521 and the high-pressure common rail pipe body 3, increase the holding force, and prevent the high-pressure common rail pipe body 3 from being pinched. The plug 4 includes a plug 41 and an annular sealing platform 42. The plug 41 is located inside the orifice of the high-pressure common rail pipe body 3, and the annular sealing platform 42 is in contact with the end face of the orifice of the high-pressure common rail pipe body 3. In this embodiment, the plug 41 is inserted into the orifice of the high-pressure common rail pipe body 3, and the annular sealing platform 42 is fitted with the end face of the orifice of the high-pressure common rail pipe body 3 to prevent the coating from entering the inner wall of the high-pressure common rail pipe body 3. The plug 4 is made of polytetrafluoroethylene material. It is worth noting that the size of the plug 4 is not limited and should be selected according to the size of all orifices such as the main oil inlet and the branch oil outlet on the high-pressure common rail pipe body 3. The top of the plug 4 is equipped with a magnetic handle (neodymium iron boron magnet) to facilitate the installation and removal of the plug 4. The sliding mechanism 7 includes two sets of crossbars 71, four sets of sliders 72 and two sets of connecting frames 73. The two sets of crossbars 71 are fixedly installed on both sides of the base 1, and the four sets of sliders 72 are slidably installed on the outer walls of the two sets of crossbars 71. The bottoms of the two sets of connecting frames 73 are fixedly connected to the four sets of sliders 72 respectively. In this embodiment, the operator can manually move the connecting frame 73, which will cause the two sets of sliders 72 connected to it to slide on the two sets of crossbars 71, adjusting the position of the two sets of connecting frames 73, and thus adjusting the position of the two sets of auxiliary support members 6. It is worth noting that since the positions of the main oil inlet, branch oil outlet and other orifices on different models of high-pressure common rail pipes are different, it is necessary to adjust the position of the two sets of auxiliary support members 6 so that the two sets of auxiliary support members 6 can provide unobstructed support for the high-pressure common rail pipe body 3. The sliding mechanism 7 is not equipped with a driving structure. When the high-pressure common rail pipe body 3 is placed on top of the two sets of auxiliary support members 6, a pressure will be applied to the two sets of auxiliary support members 6, thereby preventing the two sets of auxiliary support members 6 from automatically moving. The auxiliary support 6 includes a support base 61 and two sets of rollers 62. The support base 61 is installed on the top of the connecting frame 73. The top of the support base 61 is provided with an installation groove. The two sets of rollers 62 are symmetrically rotated and installed inside the installation groove. The outer walls of the two sets of rollers 62 are in contact with the high-pressure common rail pipe body 3. In this embodiment, the two sets of rollers 62 on the support base 61 support the high-pressure common rail pipe body 3, and the high-pressure common rail pipe body 3 can drive the rollers 62 to rotate when rotating, so supporting the high-pressure common rail pipe body 3 does not affect the rotation of the high-pressure common rail pipe body 3. Both sides of the support base 61 are fixedly connected with ear plates 8, and both sets of ear plates 8 are connected to the connecting frame 73 by bolts 9; In this embodiment, the ear plate 8 is installed on the connecting frame 73 by bolts 9, and then the auxiliary support 6 is installed, so that it can be replaced when there is a problem with the auxiliary support 6.

[0021] In this application, the first drive motor 512 can be a Delta ASD-B2 series servo motor, model ASD-B2-0421-B, and the second drive motor 522 can be a Panasonic MINASA6 series servo motor, model MSMF042L1U2M. Both the first drive motor 512 and the second drive motor 522 are existing finished products, and will not be described in detail here.

[0022] Working principle: When using this utility model, firstly, the sliding mechanism 7 drives the two sets of auxiliary support members 6 to move and adjust the position of the two sets of auxiliary support members 6. Then, the high-pressure common rail pipe body 3 to be processed is placed on the two sets of auxiliary support members 6. The two sets of auxiliary support members 6 provide unobstructed support for the high-pressure common rail pipe body 3. Then, the plugs 4 are used to block all the orifices on the high-pressure common rail pipe body 3, such as the main oil inlet and the branch oil outlet. Then, the clamping assembly 51 clamps and fixes both ends of the high-pressure common rail pipe body 3. The rotating assembly 52 can drive the high-pressure common rail pipe body 3 to rotate, which facilitates the comprehensive spraying and coating of the high-pressure common rail pipe body 3 and improves the coating efficiency.
