Description

Technical Field

[0001] This utility model relates to the field of valve seat processing technology, and in particular to a spraying device for valve seat processing. Background Technology

[0002] In the valve seat manufacturing process, spraying is a crucial step in ensuring its corrosion resistance, wear resistance, and other properties. Existing valve seat spraying equipment has the following shortcomings:

[0003] 1. The spraying mechanism lacks flexibility. The nozzle position is mostly fixed or can only be adjusted in one direction, making it difficult to adapt to the all-round spraying needs of valve seats of different sizes and shapes, which easily leads to problems such as spraying dead corners or uneven thickness.

[0004] 2. Poor valve seat positioning stability: The traditional positioning structure has a small contact area with the valve seat, which makes it prone to loosening or shifting during rotary spraying, resulting in a decrease in spraying accuracy.

[0005] 3. Low operating efficiency: Most devices can only spray a single valve seat at a time, and cannot simultaneously process valve seats at different spraying stages (such as those to be sprayed and those that have already partially dried), resulting in cumbersome process connections. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, one of the objectives of this utility model is to provide a spraying device for valve seat processing.

[0007] One of the objectives of this utility model is achieved by the following technical solution: a spraying device for valve seat processing, comprising a spraying box, an adjustable spraying mechanism provided at the top of the inner cavity of the spraying box, a positioning and rotating mechanism provided in the inner cavity of the spraying box, and a valve seat body provided in the middle of the inner cavity of the spraying box.

[0008] Furthermore, the spraying mechanism includes a first chute, which is formed at the top of the inner cavity of the spraying box. A first slider is slidably connected to the inner cavity of the first chute. The bottom end of the first slider extends into the inner cavity of the first chute. A first threaded hole is formed on the upper part of the first slider. A first threaded rod that matches the internal thread of the first threaded hole passes through the inner cavity of the first threaded hole. The rear end of the first threaded rod is movably connected to the rear sidewall of the inner cavity of the first chute. The front end of the first threaded rod passes through the front sidewall of the inner cavity of the first chute and is movably connected to it.

[0009] Furthermore, a second servo motor is fixedly connected to the front side of the spray box near the top, and the power output shaft of the second servo motor is fixedly connected to the front end of the first threaded rod.

[0010] Furthermore, a second slide groove is provided at the bottom of the first slider, and a second slider is slidably connected to the inner cavity of the second slide groove. A second threaded hole is provided on the second slider, and a second threaded rod that matches the internal thread of the second threaded hole passes through the inner cavity of the second threaded hole. The right end of the second threaded rod is movably connected to the right side wall of the inner cavity of the second slide groove, and the left end of the second threaded rod passes through the left side wall of the second slide groove and is movably connected to it. A first servo motor is fixedly connected to the left side of the first slider, and the power output shaft of the first servo motor is fixedly connected to the left end of the second threaded rod.

[0011] Furthermore, a nozzle is fixedly connected to the bottom of the second slider.

[0012] Furthermore, the positioning and rotating mechanism includes an upper arc plate and a lower arc plate, which are respectively attached to the top and bottom of the inner cavity of the valve seat body. A cylinder is fixedly connected to the top middle of the lower arc plate, and the transmission end of the cylinder is fixedly connected to the bottom of the upper arc plate.

[0013] Furthermore, a rotating shaft is fixedly connected to the left side of the lower arc plate. The front end of the rotating shaft passes through the left side wall of the spray box and is movably connected to it. A motor is fixedly connected to the left side wall of the spray box, and the power output shaft of the motor is fixedly connected to the left end of the rotating shaft.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. Flexible and adjustable spraying position to ensure uniform spraying: Through the adjustable spraying mechanism, the first servo motor drives the second threaded rod to move the second slider left and right, and the second servo motor drives the first threaded rod to move the first slider back and forth, realizing multi-dimensional adjustment of the nozzle in the horizontal direction. It can accurately adapt to the spraying needs of different positions of the valve seat, effectively avoid spraying dead corners, and improve spraying uniformity.

[0016] 2. Stable positioning and reliable rotation improve spraying quality: The positioning and rotation mechanism uses an upper arc plate and a lower arc plate that fit into the inner cavity of the valve seat. The cylinder drives the clamping to ensure that the valve seat does not loosen during the spraying process. At the same time, the motor drives the valve seat to rotate, so that all surfaces of the valve seat can be evenly covered by the spray head, further ensuring the consistency of spraying.

[0017] 3. Improve work efficiency and reduce costs: The spray box can be layered to place valve seats in different states (for example, when the upper part is being sprayed externally, the bottom part can be processed simultaneously with the valve seats that have been preliminarily dried), so as to realize multi-process parallel operation and reduce waiting time; in addition, the integrated structural design reduces the number of equipment operation steps, reduces the cost of manual intervention, and improves the overall processing efficiency.
