Description

Technical Field

[0001] The invention relates to the technical field of butterfly valve casting, in particular to a precision casting valve butterfly auxiliary device with a wax mold surface smoothed. Background Art

[0002] The main components of a butterfly valve include the valve body, valve stem, disc, and sealing ring. The valve body is typically cylindrical in design, with a relatively short axial length. It houses the disc, the core component of the butterfly valve. The valve stem connects the disc to the operating mechanism and drives the disc's rotation. The disc is a disc-shaped closing element that rotates around the valve shaft to open and close the valve.

[0003] The precision (lost wax) casting process is to use fusible materials (such as wax or plastic) to make a fusible pattern (referred to as investment pattern or model), apply several layers of special refractory coating on it, dry and harden it to form an integral shell, and then use steam or hot water to melt the pattern from the shell. The shell is then placed in a sand box and filled with dry sand molding. Finally, the casting is placed in a baking furnace and baked at high temperature. After the casting or shell is baked, molten metal is poured into it to obtain the casting.

[0004] The biggest advantage of precision casting butterfly valve components is that investment castings offer high dimensional accuracy and surface finish, reducing machining work. Only a small amount of machining allowance is required for areas with higher requirements. Some castings can even be used without machining, requiring only grinding and polishing allowances. This can significantly save machine tools, processing time, and raw metal materials.

[0005] However, the existing grinding equipment for butterfly valves in the precision casting process has a relatively simple structure and lacks a certain auxiliary clamping and fixing mechanism, which makes it inconvenient to clamp and fix the valve components, thereby affecting the casting efficiency of the butterfly valve. Summary of the Invention

[0006] The purpose of the present invention is to solve the problem that the grinding equipment proposed in the above background technology lacks a certain auxiliary clamping and fixing mechanism, which makes it inconvenient to clamp and fix the valve components, and proposes a precision casting valve butterfly auxiliary device with a smooth wax mold surface.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] The top of the screw is fixedly connected to the bottom of the L-shaped support plate, and the top of the screw is rotatably connected to the bottom of the L-shaped support plate.

[0009] Preferably, a plurality of fastening blocks are fixedly connected to the bottom of the base, and the fastening blocks are provided with fastening openings.

[0010] Preferably, a support rod is fixedly connected in the support groove, and a through opening corresponding to the support rod is provided on the transmission block.

[0011] Preferably, a plurality of symmetrically arranged guide rods are fixedly connected to one side of the L-shaped support plate, a guide block is fixedly connected to one end of the guide rod, and an annular guide rail corresponding to the guide block is provided on the fixed plate.

[0012] Preferably, the mounting plate is provided with a sliding groove corresponding to the support block, a sliding rod is fixedly connected in the sliding groove, and the support block is provided with a sliding opening corresponding to the sliding rod.

[0013] Preferably, the clamping mechanism includes an arc-shaped clamping rod, which is rotatably connected to the mounting plate through a rotating shaft. A plurality of clamping grooves corresponding to the arc-shaped clamping rod are arranged around the knob. A torsion spring is sleeved on the rotating shaft. The two ends of the torsion spring are fixedly connected to the arc-shaped clamping rod and the knob respectively.

[0015] 1. The adjustable clamping structure of the present invention can facilitate the clamping and fixing of valve components, thereby effectively improving the casting efficiency of the butterfly valve;

[0016] 2. The setting of the fastening block in the present invention can facilitate the fixation of the base.
