Description

Technical Field

[0001] The utility model relates to the technical field of boring processing of valve castings, and specifically relates to a boring device for valve castings with automatic feeding. Background Art

[0002] Valve castings are important components for controlling the flow of pipeline media, usually composed of components such as valve bodies, valve covers, valve stems, valve discs, and transmission mechanisms. Valve castings often need to be bored during actual production preparation.

[0003] Since a group of assembly holes on valve castings are often arranged at equal angles, and the boring devices for valve castings generally can only achieve boring processing of one assembly hole at a time, are not easy to continuously process, and are also not easy to achieve automatic feeding boring processing. The boring tool can only process holes with a single depth, which leads to low practicability of the device and can no longer meet people's needs. Therefore, we propose a new type of boring device for valve castings with automatic feeding to solve the above-mentioned problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a boring device for valve castings with automatic feeding to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A boring device for valve castings with automatic feeding, including a bearing frame, and also including

[0006] A horizontal drive housing, which is respectively welded to both sides inside the bearing frame. A second servo motor, a lead screw, and a nut seat are sequentially installed inside the horizontal drive housing. A drive arm welded to the nut seat is slidably connected to one side of the horizontal drive housing. A feeding type material carrier is welded between adjacent drive arms;

[0007] A cam divider, which is fixed to one end inside the feeding type material carrier. The output end of the cam divider is connected to a feeding cylinder. Electric telescopic rods, fixing parts, and pressure sensing sheets are evenly installed at the edge of the feeding cylinder;

[0008] A first servo motor and a boring tool matching the feeding type material carrier are installed on the bearing frame.

[0009] Further, the output end of the first servo motor is connected to a gear reducer, and an output shaft part is arranged at the output end of the gear reducer, which improves the smoothness effect when the first servo motor drives the boring tool to rotate.

[0010] Further, flange plates are welded on both the output shaft part and the boring tool, which facilitates the independent disassembly and replacement of the boring tool.

[0011] Further, limiting sliders are evenly welded to both the top and bottom of the feeding type material loading base, and limiting sliding rails matching the limiting sliders are arranged on the bearing frame, so that the sliding connection structure formed by the limiting sliding rails and the limiting sliders can achieve a stable effect when the feeding type material loading base moves horizontally.

[0012] Further, the second servo motor is installed at one end inside the horizontal driving machine housing, the lead screw is connected to the output end of the second servo motor, and the nut seat is threadedly connected to the lead screw.

[0013] Further, the electric telescopic rods are sequentially welded to the edge of the feeding cylinder. There are 4 electric telescopic rods, and the electric telescopic rods are arranged at equal angles on the feeding cylinder.

[0014] Further, the fixing member is connected to the output end of the electric telescopic rod, and the pressure sensing sheet is installed at one end of the fixing member away from the electric telescopic rod.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] By installing fixing members and the like, the automatic feeding valve casting boring device optimizes its own performance. On the one hand, the user can place the valve casting to be processed inside the feeding cylinder, and then simultaneously start the four equally angularly distributed electric telescopic rods to drive the fixing member to closely adhere to the outer wall of the valve casting product, realizing the automatic clamping and fixing of the product, improving the stability of subsequent processing. And by starting the cam divider fixed inside the feeding type material loading base for driving the feeding cylinder, the feeding cylinder and the product inside it can be driven to rotate at an appropriate equal division angle each time, which is convenient for realizing the continuous processing of the equally angularly arranged assembly hole groups on the valve casting, improving the working efficiency. The cam divider is a prior art and can be customized according to the actual boring requirements. And by using the pressure sensing sheet at the end of the fixing member, the pressing force on the product can also be automatically monitored to avoid the situation of being too loose or too tight when the product is fixed. On the other hand, by starting the second servo motor and cooperating with the lead screw type transmission mechanism formed by the lead screw and the nut seat, the driving arm and the feeding type material loading base welded thereon can be driven to move horizontally towards the boring processing position, which is convenient for realizing the automatic feeding boring process, thus being beneficial to meeting the requirements for different boring depths of valve castings and enhancing the applicability.
