Description

Technical Field

[0001] The utility model relates to the technical field of valve castings, in particular to a positioning device for surface processing of a silica sol wax mold of a valve casting. 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 positioning equipment is in use, such as application 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. Burns may occur during the wiping process, and it is difficult to determine the distance between the two when heating the wax mold with a hair dryer. However, in the above-mentioned technology, the ring group is distributed in a vertical structure, which is not convenient for adaptive large-scale adjustment according to the processing accuracy of the equipment during the processing. Therefore, the utility model proposes a positioning device for surface processing of valve casting silica sol wax mold to solve the problems existing in the prior art. Utility Model Content

[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment.

[0020] The positioning mechanism 3 includes a carrying plate 301, a side arm 302, a cross arm 303, a power mechanical arm 304 and an arc-shaped clip 305. The carrying plate 301 is arranged on the top side of the swinging and sliding component 2, the side of the carrying plate 301 is arranged with a side arm 302, and the cross arm 303 is arranged on the upper inner side of the side arm 302, the power mechanical arm 304 is arranged at both ends of the cross arm 303, and the output end of the power mechanical arm 304 is arranged with an arc-shaped clip 305.

[0021] The arc-shaped clip 305 is in an arc-shaped structure, and the power mechanical arm 304 has a multi-degree-of-freedom hinge structure.

[0022] In this embodiment, when in use, the product is placed on the mounting plate 301, and the upper cross arm 303 is installed through the side arm 302, so that the power mechanical arms 304 at both ends of the cross arm 303 output power to drive the output end to perform hinge transmission operation, so that the arc-shaped clamp 305 at one end of the power mechanical arm 304 clamps the product in place.

[0023] The lifting and rotating assembly 1 includes a cabinet 101, an assembly disk 102, an electric spline sleeve 103, a bearing sleeve 104, a crossbeam 105 and an electric threaded sleeve 106. The top side of the cabinet 101 is provided with an assembly disk 102 assembled with bolts, and the inner side of the assembly disk 102 is provided with an electric spline sleeve 103, and the output end of the electric spline sleeve 103 is connected with the bearing sleeve 104.

[0024] In this embodiment, when the cross beam 105 is lifted to a suitable position, the electric spline sleeve 103 on the assembly plate 102 is used to output power to drive the output end to operate, so that the operation of the electric spline sleeve 103 drives the swinging sliding component 2 to operate to a suitable angle.

[0025] A crossbeam 105 is disposed on the outer side of the bearing sleeve 104 , and output ends connected to the electric threaded sleeve strip 106 are disposed below both ends of the crossbeam 105 .

[0026] In this embodiment, when lifting operation is required, the electric threaded sleeve 106 is used to output power to drive the output end to operate, so that the electric threaded sleeve 106 spirally rotates to lift the beam 105 to a suitable height.

[0027] The swinging and sliding component 2 includes a slotted box 201, a gearbox 202, a driving motor 203, a screw 204, a slider 205, a shock absorber 206, a hinged base 207 and a cylinder 208. The slotted box 201 is arranged at the output end of the electric spline sleeve 103. One end of the slotted box 201 is provided with a gearbox 202 connected to the output end of the driving motor 203. The slotted box 201 is provided with a screw 204 connected to the output end of the gearbox 202, and the screw 204 is threadedly connected to the slider 205.

[0028] In this embodiment, the drive motor 203 is then used to output power to drive the output end to operate, so that the drive motor 203 outputs power to drive the gearbox 202 to output transmission, and then the screw rod 204 on the slot box 201 performs spiral transmission. After the screw rod 204 is spirally transmitted, the slider 205 runs to a suitable position.

[0029] Shock absorbers 206 are provided at both ends of the slider 205 , and the top side of the shock absorber 206 is hingedly connected to a cylinder 208 via a hinged base 207 .

[0030] In this embodiment, after the slider 205 moves to a suitable position, the hinged base 207 on the top side of the shock absorber 206 cooperates with the cylinder 208 to output power for telescopic operation to achieve the effect of adjusting the pitch angle, thereby facilitating users to perform effective and accurate processing operations.

[0031] The working principle of the positioning equipment for surface processing of silica sol wax mold of valve casting is as follows: when in use, the product is placed on the mounting plate 301, and the upper cross arm 303 is installed through the side arm 302, so that the power mechanical arms 304 at both ends of the cross arm 303 output power to drive the output end to perform hinge transmission operation, so that the arc-shaped clamping piece 305 at one end of the power mechanical arm 304 clamps and positions the product. When it is necessary to perform lifting operation, the electric thread sleeve 106 is used to output power to drive the output end to operate, so that the electric thread sleeve 106 spirally rotates to lift the cross beam 105 to a suitable height. When the cross beam 105 is lifted to a suitable position, the electric spline sleeve 103 on the assembly plate 102 is used to output power. After the power drives the output end to operate, the operation of the electric spline sleeve 103 drives the swing sliding component 2 to run to a suitable angle, and then the drive motor 203 outputs power to drive the output end to operate, so that the drive motor 203 outputs power to drive the gearbox 202 to output transmission, and then the screw rod 204 on the slot box 201 performs spiral transmission. After the screw rod 204 is spirally transmitted, the slider 205 runs to a suitable position. After the slider 205 runs to a suitable position, the hinged base 207 on the top side of the shock absorber 206 cooperates with the cylinder 208 to output power for telescopic operation to achieve the effect of adjusting the pitch angle, thereby facilitating users to perform effective and precise processing operations.
