Description

Technical Field

[0001] The utility model relates to the technical field of valve castings, in particular to a device for polishing the surface of a valve casting silica sol wax mold. Background Art

[0002] Valve castings are valve components produced through the casting process, mainly including valve bodies, valve covers, valve stems, valve discs and transmission mechanisms. Casting is a metal forming process that involves pouring liquid metal into a pre-made mold and forming valve parts of the desired shape after the metal cools and solidifies. Valve castings can have more flexible choices in materials, such as gray iron, ductile iron, ordinary carbon steel, alloy steel, stainless steel, copper alloy, titanium alloy, etc., among which cast iron valves and cast steel valves are more widely used. The casting process is relatively simple, and the requirements for equipment and technology are not as high as forging. It is suitable for the production of parts with complex shapes, especially those with complex internal cavities, and the cost is relatively low. However, the casting process is prone to produce pores and other defects, which may affect the performance and quality of the product.

[0003] When the existing polishing equipment is in use, such as announcement number CN111251159B, which provides a valve casting silica sol wax mold surface treatment process, the operation is completed by a base, a movable frame, a positioning bolt, a wrapping device, a ring group, a dual-purpose device, a cleaning device and a setting ring. The present invention can solve the problem that when manually wiping, the heat dissipates faster and the residue needs to be removed faster. However, the heating temperature is high, and it is difficult to remove it quickly by manual wiping.

The electric rotating seat 201 is arranged on the top side of the collecting and cleaning component 1, and the output end of the electric rotating seat 201 is provided with a cross arm 202, and a swinging cross plate 203 connected by hinges is arranged above both ends of the cross arm 202, an articulated base 204 is arranged above both ends of the swinging cross plate 203, and the inner end of the articulated base 204 is hingedly connected to the carrying plate 206 through the swing rod 205, a side frame 207 is arranged on the side of the carrying plate 206, and the inner end of the side frame 207 is connected to the second hydraulic telescopic arm 209 through the output end of the first hydraulic telescopic arm 208, and folding positioning pieces 2010 are arranged at both ends of the second hydraulic telescopic arm 209.

[0023] The first hydraulic telescopic arm 208 and the second hydraulic telescopic arm 209 are both telescopic structures, and the swinging cross plate 203, the articulated base 204 and the swinging rod 205 form a multi-degree-of-freedom structure.

[0024] In this embodiment, when in use, the raw material is placed on the top side of the mounting plate 206, and then the first hydraulic telescopic arm 208 and the second hydraulic telescopic arm 209 on the side frame 207 are telescopically operated so that the folding positioning piece 2010 clamps and positions the raw material. After clamping and positioning, the electric rotating seat 201 outputs power to drive the output end to operate, so that the swinging cross plate 203, the articulated base 204, and the swinging rod 205 are hingedly driven to facilitate the adjustment of the raw material to a suitable processing position.

[0025] The collecting and cleaning assembly 1 comprises a fixing frame 101 , a table 102 , a square cabin pipe 103 , a folding sheet 104 , an isolation connecting pipe 105 , an air pump 106 , a duct cabin 107 and a waste collection box 108 .

[0026] In this embodiment, when cleaning is required, the waste collection box 108 is used to extract the duct chamber 107 to achieve the effect of cleaning the waste residue. Since the folding piece 104 is in a folding shape, it can prevent overflow.

[0027] The inner bottom side of the table 102 is sleeved with a cabin pipe 103 with a folding piece 104 installed, and the lower part of the cabin pipe 103 is sleeved with a duct cabin 107 with a waste collection box 108 installed.

[0028] In this embodiment, when slag removal is required, the vacuum pump 106 at one end of the isolation connecting pipe 105 is used to output power to drive the output end to operate so that the vacuum pump 106 can extract the waste slag, which falls into the waste collection box 108 in the duct cabin 107 through the square cabin pipe 103 and the folding sheet 104 to achieve an effective collection effect.

[0029] The polishing and grinding mechanism 3 includes a side column 301, a guard plate 302, a cross cabin 303, an electric screw group 304, a slider 305, a hydraulic telescopic frame 306, a rotating motor 307, an electric articulated seat 308, a power chassis arm 309, a servo motor 3010, a spline sleeve 3011 and a grinding head 3012. The side column 301 is arranged above the side of the table plate 102, the side of the side column 301 is provided with a guard plate 302, the top side of the side column 301 is provided with a cross cabin 303, and the slider 305 is threadedly connected to the cross cabin 303 through the electric screw group 304.

[0031] A hydraulic telescopic frame 306 is arranged on the side of the slider 305, and an electric articulated seat 308 connected to the output end of the rotating motor 307 is arranged below the hydraulic telescopic frame 306, a power chassis arm 309 is arranged at the output end of the electric articulated seat 308, and a servo motor 3010 is arranged at the output end of the power chassis arm 309, a spline sleeve 3011 is arranged at the output end of the servo motor 3010, and a plug-in connected grinding head 3012 is arranged at the output end of the spline sleeve 3011.

[0032] In this embodiment, when the slider 305 slides to a suitable position, the hydraulic telescopic frame 306 outputs power to drive the output end to telescope, so that the output end of the rotating motor 307 outputs power to drive the electric articulated seat 308 to run to a suitable direction, and then the power box arm 309 is used to adjust the hinge transmission so that one end of the power box arm 309 is adjusted to a suitable position, and then the servo motor 3010 outputs power to drive the output end to perform output transmission so that the grinding head 3012 at one end of the spline sleeve 3011 performs a grinding operation on the product.

[0033] The working principle of the valve casting silica sol wax mold surface grinding equipment is: when in use, the raw material is placed on the top side of the mounting plate 206, and then the first hydraulic telescopic arm 208 and the second hydraulic telescopic arm 209 on the side frame 207 are used to telescope and operate so that the folding positioning piece 2010 clamps and positions the raw material, and after clamping and positioning, the electric rotating seat 201 outputs power to drive the output end to operate so that the swinging cross plate 203, the hinged base 204, and the swing rod 205 are hingedly driven so that the raw material can be adjusted to a suitable processing position. When processing is required, the side column 301 and the guard plate 302 are used for protective support, and the output end of the cross cabin 303 is used to output power to drive the output end to operate so that the electric screw group 304 on the cross cabin 303 outputs power to drive the output end to operate so that the slider 305 runs to a suitable processing position. When the slider 305 slides to a suitable position, the hydraulic telescopic frame 306 outputs power. After the power drives the output end to extend and retract, the output power of the rotating motor 307 drives the electric articulated seat 308 to move to a suitable direction. Then, the power chassis arm 309 is used to adjust the hinge transmission so that one end of the power chassis arm 309 is adjusted to a suitable position. Then, the servo motor 3010 is used to output power to drive the output end to perform output transmission so that the grinding head 3012 at one end of the spline sleeve 3011 performs grinding operation on the product. When slag removal is required, the vacuum pump 106 at one end of the isolation connecting pipe 105 is used to output power to drive the output end to operate so that the vacuum pump 106 can extract waste slag, which falls into the waste collection box 108 in the duct cabin 107 through the square cabin pipe 103 and the folding piece 104 to achieve an effective collection effect. When cleaning is required, the waste collection box 108 is used to extract the duct cabin 107 to achieve the effect of cleaning the waste slag. Since the folding piece 104 is in a folded structure, it can prevent overflow.
