Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically a valve grinding device. Background Technology

[0002] Valves are control components in fluid transport systems, possessing functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, flow diversion, and pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to the various valves used in highly complex automated control systems. Their types and specifications are quite diverse, and they can be used to control the flow of various types of fluids, including air, water, steam, various corrosive media, slurry, oil, liquid metals, and radioactive media.

[0003] During valve production, the sealing surface needs to be ground. The flatness and roughness of the valve sealing surface directly affect the sealing effect. When fixing the valve with the existing grinding equipment, it is inconvenient because the valve types and shapes are different and the curvature of the middle part and the two side surfaces are different. During grinding, the valve is prone to slippage, which affects the grinding efficiency.

[0004] Therefore, we propose a valve grinding device to solve the above problems. Utility Model Content

[0009] A valve grinding device includes: a base, a housing disposed on the base, a first movable bracket installed inside the housing, a rotating bracket installed on the side of the base away from the housing, and a second movable bracket installed on the rotating bracket.

[0010] It also includes: a set of protrusions located inside the outer shell on the base, a set of lead screws installed inside the protrusions, a screw sleeve that cooperates with the lead screws on the bottom of the first movable bracket, allowing the first movable bracket to move inside the protrusions along the setting direction of the lead screws, a rotating bracket having the same protrusions and positive and negative threaded lead screws as the base, and a second movable bracket cooperating with the positive and negative threaded lead screws through the screw sleeves set at the bottom;

[0011] The top of the second movable bracket is equipped with a first connecting rod and a second connecting rod on both sides respectively. The first connecting rod and the second connecting rod are connected by a set of limiting pins. The first connecting rod and the second connecting rod are provided with waist-shaped slots of the same size, which allows the first connecting rod and the second connecting rod to move along the opening direction of the waist-shaped slots while the limiting pins connect the first connecting rod and the second connecting rod.

[0012] Furthermore, a set of first motors is installed on the top of the first movable bracket, and a rotating shaft is provided on the drive end of one side of the first motor. The grinding disc is connected to the first motor through the rotating shaft.

[0013] Furthermore, a second motor is installed inside the protrusion fixed on the base, which can drive the first movable bracket to move on the lead screw through a threaded connection.

[0014] Furthermore, two sets of slots are respectively opened on both sides of the top of the second movable bracket, and a protrusion matching the size of the slot is provided on one side of both the first connecting rod and the second connecting rod. The first connecting rod and the second connecting rod are rotatably connected to the second movable bracket by means of the protrusion.

[0016] Beneficial effects

[0017] Compared with the prior art, the present invention provides a valve grinding device, which has the following beneficial effects:

[0018] This invention utilizes a rotating bracket with a connecting frame fixed at the bottom, connected to a rotating cylinder installed inside the base. A first movable bracket is installed on the other side of the base. A grinding disc mounted on the first movable bracket grinds the valve face placed above the rotating bracket. After grinding one side of the face, the rotating cylinder drives the rotating bracket to rotate, allowing grinding of the other side. Because the first movable bracket can move on a lead screw, it can grind valves of different sizes. Two sets of second movable brackets are installed above the rotating bracket. Limiting rods fixed on both sides of the second movable brackets limit the valve's position. A first connecting rod and a second connecting rod mounted on the top of the second movable brackets further limit the valve's top position. These two sets of limiting rods in different directions effectively solve the problem of valve rotation caused by loose fixing of the curved surface during grinding. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] like Figure 1-5As shown, an embodiment of this utility model discloses a valve grinding device, comprising: a base 1, a housing 2 mounted on the base 1, a first movable support 3 installed inside the housing 2, a rotating support 4 mounted on the side of the base 1 away from the housing 2, and a second movable support 5 mounted on the rotating support 4; further comprising: a set of protrusions provided on the base 1 inside the housing 2, a set of lead screws 6 installed inside the protrusions, a threaded sleeve provided at the bottom of the first movable support 3 to cooperate with the lead screws 6, allowing the first movable support 3 to move inside the protrusions along the setting direction of the lead screws 6, and a second motor 14 provided on one side inside the protrusions, driving the second motor 14 to drive the lead screws 6 to rotate inside the protrusions, thereby driving the first movable support 3 to move inside the protrusions. The grinding disc 16 connected to the rotating shaft on the drive end of the first motor 13 mounted on the top of the first movable bracket 3 is used to grind the end face of the valve 15 placed on one side of the rotating bracket 4. The rotating bracket 4 is provided with the same protrusion and positive and negative threaded rods 7 as the base 1. The two sets of second movable brackets 5 are engaged with the opposite threads on the positive and negative threaded rods 7 through the screw sleeves set at the bottom. The top of the rotating bracket 4 is also provided with guide rails on both sides to guide the second movable brackets 5. When the third motor 17 mounted on one side of the positive and negative threaded rods 7 is driven, the second movable brackets 5 can move inward or outward at the same time. It can clamp the corners of valves 15 of different sizes and limit the horizontal movement. The height of the top of the second movable bracket 5 can also be adjusted according to the size of the valve 15 being processed. Two sets of slots are respectively opened on both sides of the top of the second movable bracket 5. A protrusion matching the size of the slot is provided on one side of both the first connecting rod 8 and the second connecting rod 9. The first connecting rod 8 and the second connecting rod 9 are rotatably connected to the second movable bracket 5 via the protrusion. A set of limiting pins 10 connects the first connecting rod 8 and the second connecting rod 9. The first connecting rod 8 and the second connecting rod 9 have the same size waist-shaped slot, allowing the limiting pins 10 to move along the opening direction of the waist-shaped slot while connecting the first connecting rod 8 and the second connecting rod 9. Threaded holes are opened on the side of the first connecting rod 8 and the second connecting rod 9 away from the second movable bracket 5. Tensioning bolt 18 is installed on the threaded holes of the first connecting rod 8 and the second connecting rod 9 respectively by threaded connection. The position of the limit pin 10 in the waist-shaped groove can be adjusted by tightening tensioning bolt 18. A set of connecting frames 11 is also fixed on the bottom of the rotating bracket 4. A set of rotating cylinders 12 is installed on the side of the base 1 away from the outer shell 2. The connecting frame 11 is connected and fixed to the rotating cylinder 12 by opening the same round hole as the driving end of the rotating cylinder 12 and by using positioning bolts. This allows the rotating cylinder 12 to drive the connecting frame 11 and the rotating bracket 4 above the connecting frame 11 to rotate. The valve 15 can be rotated while the two sets of second moving brackets 5 are clamping it.

[0028] During processing, the valve 15 is first placed between two sets of second movable supports 5 above the rotating support 4. The third motor 17, located on one side of the positive and negative threaded rods 7 on the rotating support 4, is driven to make the positive and negative threaded rods 7 rotate inside the protrusion. The connection between the two sets of second movable supports 5 and the positive and negative threaded rods 7 is used to clamp the four corners of the valve 15, thereby restricting its horizontal movement. While the two sets of second movable supports 5 are clamping inward, the rotational connection between the first connecting rod 8 and the second connecting rod 9 installed on the top of the second movable support 5 and the second movable support 5 allows the first connecting rod 8 and the second connecting rod 9 to move outward according to the shape of the protrusion when they contact the protrusion on the top of the valve 15. Then, the tensioning bolt 18 installed on one side of the first connecting rod 8 and the second connecting rod 9 is turned, and the tensioning bolt 18 contacts the limit pin 10 to limit its movement. This limits the top sides of valve 15, restricting its rotation. Then, the second motor 14, located inside the protrusion on one side of the base 1, drives the first moving bracket 3 to move on the lead screw 6. Simultaneously, the first motor 13, mounted on the top of the first moving bracket 3, drives the grinding disc 16 to grind the end face of valve 15. After grinding one side of the end face, the lead screw 6 is rotated by the external control system, moving the first moving bracket 3 to a position that does not affect the rotation of valve 15. Then, the rotating cylinder 12, located inside one side of the base 1, drives the connecting frame 11 fixed at the bottom of the rotating bracket 4 to rotate, thus flipping the valve. Finally, the first moving bracket 3 is driven forward to grind the other side of valve 15. After completion, the third motor 17 is driven again to reverse the forward and reverse threaded lead screw 7, removing the limit and allowing valve 15 to be removed. It can reduce the operation time required for tightening and loosening bolts in traditional grinding devices, and can be quickly removed and installed, saving manpower. At the same time, it can effectively solve the problem of valve 15 rotating during grinding due to loose arc surface fixation by two sets of limit switches in different directions.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
