Description

Technical Field

[0001] This utility model relates to the technical field of valve processing equipment, specifically a multi-angle grinding device for valve production. Background Technology

[0002] Valves are control components in fluid transport systems, enabling the regulation and control of parameters such as fluid flow, pressure, etc. They are widely used in many industrial fields such as petroleum, chemical, water treatment, and energy, and are key equipment to ensure the stable operation of process flows. Common valve types include gate valves, ball valves, globe valves, etc. Different types of valves are suitable for different working conditions based on their structure and working principle.

[0003] During valve manufacturing, the valve body's shape, end face, and internal channels are initially machined using lathes and milling machines. CNC machine tools are then used to perform precision machining on key parts such as the valve body's sealing surface, connecting threads, and flange end face. Depending on the sealing requirements, milling, grinding, or polishing processes are employed to ensure a proper fit with the valve seat. The machined components are then assembled into a complete valve, and multiple rounds of testing are conducted to ensure its performance meets the standards.

[0004] Traditional valve grinding requires multiple workpiece flips and orientation adjustments, and each flip requires repositioning and fixing. Frequent clamping leads to longer processing time and reduced processing efficiency.

[0005] Therefore, a multi-angle grinding device for valve production is proposed to address the above problems. Utility Model Content

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a multi-angle grinding device for valve production includes a processing table 1; multiple support legs 11 are fixedly connected to the bottom of the processing table 1; a set of first electric push rods 12 are installed on the top of the processing table 1; a top plate 13 is fixedly connected to the top of the first electric push rods 12; a reciprocating motor 14 is installed at the bottom of the top plate 13; a mounting plate 15 is fixedly connected to the load end of the reciprocating motor 14; a second electric push rod 16 is fixedly connected to the bottom of the mounting plate 15; a driven electric push rod is rotatably connected to one side of the mounting plate 15. Plate 17; a drive plate 18 is rotatably connected to the end of the driven plate 17; one side of the drive plate 18 is rotatably connected to the output end of the second electric push rod 16; a rotary motor 19 is mounted on the top of the drive plate 18; a grinding head 110 is fixedly connected to the output end of the rotary motor 19; a stepper motor 111 is mounted on the bottom of the processing table 1; a rotating disk 112 is fixedly connected to the output end of the stepper motor 111; a clamp 113 is mounted on the top of the rotating disk 112; during operation, the valve is placed on the surface of the rotating disk 112 and... The clamp 113 is fixed, the first electric actuator 12 is controlled to move up and down, the reciprocating motor 14 is controlled to move left and right to grind the top of the valve, the second electric actuator 16 is controlled to retract, so that the connection end between the driven plate 17 and the drive plate 18 moves away from the second electric actuator 16, so that the grinding head 110 and the second electric actuator 16 are in a horizontal state, and cooperate with the reciprocating motor 14 and the first electric actuator 12 to grind the side of the valve, and the stepper motor 111 is controlled to rotate the rotating disk 112 by a specified angle to grind the different surfaces of the valve. The first electric push rod 12 adjusts the height of the grinding head 110, which can accommodate valve tops of different thicknesses. The stepper motor 111 drives the valve to rotate, allowing the grinding head 110 to perform circumferential grinding on the valve top, increasing the uniformity of grinding. The second electric push rod 16 is controlled to retract, changing the grinding head 110 from a horizontal to a vertical state. This, together with the first electric push rod 12 and the reciprocating motor 14, grinds the outer surface of the valve, reducing the time required to flip the workpiece to adjust its orientation and increasing processing efficiency.

[0026] like Figure 4As shown, a positioning plate 2 is fixedly connected to the top of the rotating disk 112; the positioning plate 2 is the same size as the valve end through hole; a column 21 is fixedly connected to the top of the rotating disk 112; a concave block 22 is fixedly connected to the top of the column 21; the top of the concave block 22 is V-shaped; during operation, when the valve is placed on the surface of the rotating disk 112, the valve end through hole is fitted onto the positioning plate 2 for positioning, so that it rotates around the center of the stepper motor 111 when rotating. The side through hole of the valve is placed on the top of the concave block 22 to fix the valve position. By fitting the valve onto the positioning plate 2, the rotation axis of the valve is kept consistent with the stepper motor 111, reducing eccentric rotation caused by clamping offset and increasing the uniformity of grinding in the circumferential direction. The side through hole of the valve is placed on the top of the concave block 22. The V-shaped structure of the concave block 22 centers the valve side through the inclined surfaces on both sides, forming a radial limit, increasing clamping consistency, reducing adjustment time, and shortening the processing cycle.

[0027] like Figure 1 , Figure 2 and Figure 4 As shown, a set of through grooves 3 are provided on the top of the processing table 1; the through grooves 3 are provided on both sides of the rotating disk 112; a set of collection boxes 31 are fixedly connected to the bottom of the processing table 1; the collection boxes 31 are arranged correspondingly to the through grooves 3; a drawer 32 is slidably connected to one side of the collection box 31; during operation, the grinding debris on the surface of the processing table 1 falls from the through grooves 3 into the collection box 31 for collection, and then the drawer 32 is slid to remove the debris from the collection box 31 for cleaning. By providing through grooves 3 on both sides of the rotating disk 112, the debris can fall into the collection box 31, reducing the accumulation on the surface of the processing table 1 or the scattering around the equipment. When cleaning the collection box 31, the drawer 32 can be pulled out to complete the cleaning, increasing the convenience of cleaning and reducing the difficulty of cleaning.

[0028] like Figures 1 to 4 As shown, multiple scrapers 4 are fixed to the side of the rotating disk 112; the scrapers 4 are inclined; during operation, when the rotating disk 112 rotates, the scrapers 4 push the debris on the surface of the processing table 1 to the surroundings, reducing the amount of debris entering the gap between the processing table 1 and the rotating disk 112. By setting scrapers 4 on the side of the rotating disk 112, the debris can move to the surroundings along the inclined surface of the scrapers 4 when the rotating disk 112 rotates, reducing the amount of debris entering the gap between the processing table 1 and the rotating disk 112 and causing jamming, thus reducing the risk of wear.

[0029] like Figures 1 to 3 As shown, a lighting lamp 5 is fixedly connected to one side of the drive plate 18; the lighting lamp 5 is set on the side away from the rotary motor 19; when working, the lighting lamp 5 has a built-in battery, and when the lighting lamp 5 is turned on, it emits light from its end to illuminate the grinding area, so as to detect defects in time. By installing the lighting lamp 5 on the side of the rotary motor 19, the light can be directly focused on the grinding area, so that the defects on the valve surface can be clearly displayed, thereby increasing the product qualification rate.

[0030] like Figures 1 to 2 As shown, the bottom of the support leg 11 is threaded with an adjusting foot pad 6; the bottom of the adjusting foot pad 6 is fixed with a rubber pad; during operation, the adjusting foot pad 6 is rotated so that its end enters the support leg 11 to adjust the horizontal state of the processing table 1. By rotating the adjusting foot pad 6, the height of each support leg 11 is adjusted so that the processing table 1 is kept horizontal, which can reduce the wear caused by the tilt of the rotating shaft and extend the service life of the equipment.

[0031] Working principle: By placing the valve on the surface of the rotating disk 112 and fixing it with the clamp 113, the first electric actuator 12 is controlled to move up and down, and the reciprocating motor 14 is controlled to move left and right to grind the top of the valve. The second electric actuator 16 is controlled to retract, causing the connection end between the driven plate 17 and the drive plate 18 to move away from the second electric actuator 16, so that the grinding head 110 and the second electric actuator 16 are in a horizontal state. In cooperation with the reciprocating motor 14 and the first electric actuator 12, the side of the valve is ground. The stepper motor 111 is controlled to rotate the rotating disk 112 to a specified angle, so that different sides of the valve come into contact with the grinding head 110. When the valve is placed on the surface of the rotating disk 112, the through hole at the end of the valve is fitted into the positioning... Positioning is done on disc 2 so that it rotates around the center of stepper motor 111. The side port of the valve is placed on top of concave block 22 to fix the valve position. Grinding debris on the surface of processing table 1 falls from through groove 3 into collection box 31 for collection. Then, drawer 32 is slid to remove debris from collection box 31 for cleaning. When disc 112 rotates, scraper 4 pushes debris on the surface of processing table 1 to the surroundings to reduce debris entering the gap between processing table 1 and disc 112. Light lamp 5 has a built-in battery. Turning on light lamp 5 allows it to emit light from its end to illuminate the grinding area and detect defects in time. Rotate adjusting foot pad 6 so that its end enters the support leg 11 to adjust the level of processing table 1.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
