[0002] During the production and processing of metal pipe fittings, spraying operations need to be carried out on some pipe fittings so that the pipe fittings can operate in a specified environment. When spraying metal pipe fittings, spraying jigs need to be used for auxiliary cooperation;

[0003] A Chinese patent with the publication number CN218554459U discloses a jig for spraying pipe fittings, belonging to the technical field of pipe fitting spraying. It includes a bottom plate, on which two side plates and a driving motor are fixed, and a first hollow turntable and a second hollow turntable are provided. Straight slots are opened inside both the first hollow turntable and the second hollow turntable, and two clamping plates are provided. The centers of the outer sides are respectively fixed with a first rotating shaft and a second rotating shaft, and a sliding rod and a hydraulic cylinder are fixed inside. A first bevel gear is fixed on the first rotating shaft. Two moving blocks are connected to the sliding rod. The bottom end of the moving block is connected to a driving rod through a first connecting block. The piston rod of the hydraulic cylinder is connected to a moving plate, and the other ends of the two driving rods are connected to the moving plate through a second connecting block. The clamping plate and the two moving blocks are connected through a movable rod. The output end of the driving motor is connected to a second bevel gear through a round rod; when using this jig, the fixing of the pipe fitting is good, and it will not shift during spraying, ensuring its spraying effect;

[0004] When the above-mentioned jig for spraying pipe fittings is in use, the jig will occupy the spraying surfaces at both ends of the pipe fitting, affecting the spraying operation range, and subsequent supplementary processing of the pipe fitting is required, prolonging the processing steps of the spraying operation, resulting in a low spraying operation efficiency for the pipe fitting; therefore, a spraying jig for metal pipe fittings is proposed to solve the above problems. Content of the Utility Model

[0005] In order to make up for the deficiencies of the prior art and solve some existing problems of the spraying jig for metal pipe fittings, the utility model proposes a spraying jig for metal pipe fittings.

[0007] A lifting device is installed on the shaft body of the fixing shaft; lifting rods are installed on the upper and lower structural surfaces of the lifting device; lifting blocks are fixedly connected to the ends of the lifting rods; rubber strips are installed at both ends of the lifting blocks; clamping of the vertical surfaces at both ends of the pipe fitting is achieved.

[0008] Preferably, the movement trajectory of the spraying mechanism does not intersect with the movement trajectory of the fixing plate; the pressure sensor acts on the lifting device; ensuring the smooth operation of the fixing plate.

[0009] Preferably, a small motor is installed on the vertical surface of one side of the main board; one end of the bidirectional lead screw passes through the board body of the main board and is connected to the small motor; providing power for the rotation of the bidirectional lead screw.

[0010] Preferably, mounting holes are symmetrically opened at the positions on both sides of the opening of the adjustment groove on the top end surface of the main board; a telescopic cylinder is installed inside the mounting hole; a telescopic rod is installed on the top of the telescopic cylinder; a support plate is fixedly connected to the top of the telescopic rod; facilitating the clamping operation of the pipe fitting.

[0011] Preferably, a positioning groove is opened on the top end surface of the support plate; when the support plate is in close contact with the connection frames on both sides, the ends of the fixing shafts thereon are in contact; realizing the limiting effect on the pipe fitting during the clamping process.

[0012] Preferably, when the telescopic rod contracts to the shortest distance, the horizontal plane where the top end surface of the support plate is located is lower than the horizontal plane where the bottom cutting surface of the fixing plate is located; enabling the support plate to operate smoothly.

[0013] The beneficial effects of the present utility model are as follows:

[0014] Through the structural design of the auxiliary clamping device, the pipe fittings to be sprayed are placed in the positioning groove of the support plate. The telescopic cylinder inside the mounting hole is started, and the telescopic rod pushes the support plate upward to a suitable position. Then the small motor is started, and the bidirectional lead screw inside the adjustment groove rotates, causing the connecting block to drive the connecting frame to move towards each other. The fixed shaft drives the lifting device to move towards each other accordingly and insert into the inside of the pipe fitting. As the connecting frames approach each other, the pipe fitting comes into contact with the abrasive pads and acts on the pressure sensor. Due to the force on the pressure sensor, the lifting device inside the structural cavity of the pipe fitting operates, and the lifting rod drives the lifting block and the rubber strip to move towards the inner wall surface of the pipe fitting, making the rubber strip closely adhere to the pipe wall of the pipe fitting. Then, the spraying mechanism is started, and with the rotational cooperation of the rotating mechanism, spraying along with the pipe fitting is achieved, avoiding the spraying surface of the pipe fitting being covered by the fixture, reducing subsequent supplementary operation steps, and improving the efficiency of the pipe fitting spraying operation.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 As shown, a spraying fixture for metal pipe fittings includes a main board 1; cushion blocks 2 are fixedly connected to the four corners at the bottom of the main board 1; a spraying mechanism 3 is installed on one side of the top of the main board 1; an auxiliary clamping device is installed on the main board 1; the auxiliary clamping device includes an adjustment groove 401; a bidirectional lead screw 402 is rotatably installed inside the adjustment groove 401; connection blocks 403 are sleeved and installed on the outer sections at both ends of the bidirectional lead screw 402; a connection frame 404 is fixedly connected to the top of the connection block 403; a rotating mechanism 405 is installed on the frame body of the connection frame 404; fixing plates 406 are installed on the opposite structural surfaces of the rotating mechanism 405; a fixed shaft 409 is installed on the structural surface of the fixing plate 406; a pressure sensor 407 is installed around the fixed shaft 409 on the structural surface of the fixing plate 406; a frosted pad 408 is installed on the acting surface of the pressure sensor 407;

[0023] A lifting device 410 is installed on the shaft body of the fixed shaft 409; lifting rods 411 are installed on the upper and lower structural surfaces of the lifting device 410; lifting blocks 412 are fixedly connected to the ends of the lifting rods 411; rubber strips 413 are installed at both ends of the lifting block 412; the movement track of the spraying mechanism 3 does not intersect with the movement track of the fixing plate 406; the pressure sensor 407 acts on the lifting device 410; a small motor 414 is installed on the vertical surface of one side of the main board 1; one end of the bidirectional lead screw 402 passes through the board body of the main board 1 and is connected to the small motor 414;

[0024] During operation, in the process of manufacturing metal pipe fittings, some pipe fittings need to be spray-painted so that they can operate in a specified environment. When spray-painting metal pipe fittings, a spray fixture is required for auxiliary cooperation. When the above-mentioned fixture for spray-painting pipe fittings is in use, the fixture will occupy the spray surfaces at both ends of the pipe fitting, affecting the scope of the spray-painting operation. Follow-up supplementary processing of the pipe fitting is required, which prolongs the processing steps of the spray-painting operation and results in a low spray-painting operation efficiency for the pipe fitting. In this application, the auxiliary clamping device is used. The small motor 414 is started, and the bidirectional lead screw 402 inside the adjustment groove 401 rotates, causing the connecting block 403 to drive the connecting frame 404 to move towards each other. The fixed shaft 409 drives the lifting device 410 to move towards each other accordingly and insert into the inside of the pipe fitting. As the connecting frames 404 approach each other, the pipe fitting comes into contact with the abrasive pad 408 and acts on the pressure sensor 407. The model of the pressure sensor 407 is: PT124G-210. When the pressure sensor 407 is subjected to force, the lifting device 410 inside the structural cavity of the pipe fitting operates. The lifting rod 411 drives the lifting block 412 and the rubber strip 413 to move towards the inner wall surface of the pipe fitting, causing the rubber strip 413 to closely adhere to the pipe wall of the pipe fitting. Then, the spray-painting mechanism 3 is started, and with the rotational cooperation of the rotating mechanism 405, spray-painting of the pipe fitting is achieved, avoiding the spray surface of the pipe fitting being covered by the fixture.

[0025] On the top end surface of the main board 1, mounting holes 415 are symmetrically opened on both sides of the opening of the adjustment groove 401; a telescopic cylinder 416 is installed inside the mounting hole 415; a telescopic rod 417 is installed on the top of the telescopic cylinder 416; the top of the telescopic rod 417 is fixedly connected to a support plate 418; a positioning groove 419 is opened on the top end surface of the support plate 418; when the support plate 418 closely adheres to the two connecting frames 404, the ends of the fixed shafts 409 thereon come into contact; when the telescopic rod 417 contracts to the shortest distance, the horizontal plane where the top end surface of the support plate 418 is located is lower than the horizontal plane of the bottom cutting surface of the fixing plate 406;

[0026] During operation, the pipe fitting to be spray-painted is placed in the positioning groove 419 of the support plate 418, and the telescopic cylinder 416 inside the mounting hole 415 is started. The telescopic rod 417 pushes the support plate 418 to move upward to a suitable position, facilitating the quick clamping of the fixture.

[0027] Working principle: During the production and processing of metal pipe fittings, spraying operations need to be performed on some pipe fittings so that the pipe fittings can operate in a specified environment. When spraying metal pipe fittings, spraying jigs need to be used for auxiliary cooperation; when the above-mentioned jigs for spraying pipe fittings are in use, the jigs will occupy the spraying surfaces at both ends of the pipe fittings, affecting the scope of the spraying operation. Subsequent supplementary processing of the pipe fittings is required, which prolongs the processing steps of the spraying operation and results in a low spraying operation efficiency for the pipe fittings. In this application, the auxiliary clamping device is used. The pipe fitting to be sprayed is placed in the positioning groove 419 of the support plate 418. The telescopic cylinder 416 inside the mounting hole 415 is started, and the telescopic rod 417 pushes the support plate 418 upward to a suitable position. The small motor 414 is started, and the bidirectional lead screw 402 inside the adjustment groove 401 rotates, causing the connecting block 403 to drive the connecting frame 404 to move towards each other. The fixed shaft 409 drives the lifting device 410 to move towards each other accordingly and insert into the inside of the pipe fitting. As the connecting frames 404 approach each other, the pipe fitting comes into contact with the abrasive pad 408 and acts on the pressure sensor 407. The model of the pressure sensor 407 is: PT124G-210. Due to the force on the pressure sensor 407, the lifting device 410 inside the structural cavity of the pipe fitting operates. The lifting rod 411 drives the lifting block 412 and the rubber strip 413 to move towards the inner wall surface of the pipe fitting, causing the rubber strip 413 to closely adhere to the pipe wall of the pipe fitting. Then, the spraying mechanism 3 is started, and with the rotational cooperation of the rotating mechanism 405, spraying of the pipe fitting is achieved, avoiding the spraying surface of the pipe fitting being covered by the jig, reducing subsequent supplementary operation steps, and improving the spraying operation efficiency of the pipe fitting.
