Description

Technical Field

[0001] This utility model relates to the field of valve processing technology, and in particular to a gate valve grinding device with high-efficiency grinding performance. Background Technology

[0002] A gate valve is an opening and closing element consisting of a gate. The direction of the gate's movement is perpendicular to the direction of fluid flow. Gate valves can only be fully open or fully closed; they cannot be used for regulation or throttling. Gate valves achieve sealing through the contact between the valve seat and the gate. Typically, the sealing surface is overlaid with metal material to increase wear resistance. Depending on the type of gate, gate valves are classified as rigid gate valves and resilient gate valves. As an important component in pipeline systems used to control the flow of fluid, the surface quality of key parts such as the gate and valve seat directly affects the sealing performance and service life of the gate valve. During the manufacturing process of gate valves, grinding equipment is required to polish the equipment parts.

[0003] However, the existing equipment has the following shortcomings: when clamping different types of materials, the existing equipment needs to replace the corresponding clamping device to clamp the materials. Generally, the clamping device is fixed to the mounting head with bolts. The installation and removal of bolts is too cumbersome, resulting in low replacement efficiency for users.

[0004] Therefore, we propose a gate valve grinding device with high-efficiency grinding performance to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where it is difficult to quickly replace the clamps, resulting in low replacement efficiency for users. This invention proposes a gate valve grinding device with high-efficiency grinding performance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a gate valve grinding device with high-efficiency grinding performance, comprising a base, a connecting column, a movable arm, a cylinder, a grinder, and a replacement device. The cylinder is fixedly connected to the upper surface of the base, the connecting column is fixedly connected to the side of the base, the movable arm is mounted on the surface of the connecting column, the grinder is mounted on the surface of the movable arm, and the replacement device is mounted on the telescopic end of the cylinder. The replacement device includes an installation head and a clamp. The installation head is fixedly connected to the telescopic end of the cylinder, the clamp is mounted on one end of the installation head, and a rod is fixedly connected to the end of the clamp near the installation head. The rod is inserted into the interior of the installation head, and a positioning hole is formed on the surface of the rod. A limit plate is fixedly connected to the surface of the installation head, a pressure frame is slidably connected inside the limit plate, a movable plate is fixedly connected inside the pressure frame, and a positioning rod is fixedly connected to the upper end of the movable plate.

[0007] Furthermore, the positioning rod is inserted and connected inside the positioning hole, and a sliding rod is fixedly connected inside the pressure frame. By setting the positioning rod, the insertion rod can be limited, reducing the possibility that the insertion rod may easily detach from the installation head during use, making it difficult to stabilize the clamp.

[0008] Furthermore, a first spring is sleeved and connected to the surface of the slide rod.

[0009] Furthermore, one end of the first spring is fixedly connected to the inside of the pressure frame, and the other end of the first spring away from the pressure frame is fixedly connected to the surface of the limiting plate. The first spring is provided to facilitate the application of a reset force to the pressure frame.

[0010] Furthermore, an auxiliary component is fixedly installed at the lower end of the grinder. The auxiliary component includes a protective cover and a mounting ring. The mounting ring is fixedly connected to the lower end of the grinder, and the protective cover is installed below the grinder. A connecting ring is fixedly connected to the upper end of the protective cover. The connecting ring is inserted into the interior of the mounting ring. A pull hole is opened on the surface of the mounting ring, and an insert plate is slidably connected inside the pull hole. One end of the insert plate is inserted into the interior of the connecting ring, and a limit rod is fixedly connected inside the insert plate. By setting up the protective cover, the waste material under grinding can be blocked, reducing the situation where waste material is easily splashed around when the equipment is in use.

[0011] Furthermore, the limiting rod is slidably connected inside the pull hole, and a second spring is sleeved and connected to the surface of the limiting rod.

[0012] Furthermore, one end of the second spring is fixedly connected to the inside of the insert plate, and the other end of the second spring away from the insert plate is fixedly connected to the inside of the mounting ring. The second spring is provided to facilitate the application of a reset force to the insert plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting a replacement device, the clamp can be effectively replaced, thus reducing the need to replace the corresponding model of clamp when clamping different types of materials in existing equipment. Generally, the clamp is fixed to the mounting head with bolts, and the installation and removal of bolts are too cumbersome, resulting in low replacement efficiency for users. This replacement device enables quick replacement of the clamp and improves the user's replacement efficiency.

[0014] 2. In this utility model, by setting an auxiliary component, the protective cover is effectively installed, which plays the role of installing a protective cover. This reduces the situation where, when the grinder grinds the material on the surface of the clamp during the use of existing equipment, the waste material from grinding is easily carried by the grinder and splashes everywhere, polluting the environment around the equipment. This auxiliary component blocks the waste material from grinding, facilitates the centralized discharge of waste material, and improves the practicality of the equipment. Attached Figure Description

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] Please see Figures 1-5This utility model provides a technical solution: a gate valve grinding device with high-efficiency grinding performance, including a base 1, a connecting column 2, a moving arm 3, a cylinder 4, a grinder 5 and a replacement device 6. The cylinder 4 is fixedly connected to the upper surface of the base 1, the connecting column 2 is fixedly connected to the side of the base 1, the moving arm 3 is installed on the surface of the connecting column 2, and the grinder 5 is installed on the surface of the moving arm 3.

[0021] The specific settings and functions of the replacement device 6 and auxiliary components 7 will be explained in detail below.

[0022] In this embodiment: the replacement device 6 is installed at the telescopic end of the cylinder 4. The replacement device 6 includes an installation head 61 and a clamp 62. The installation head 61 is fixedly connected to the telescopic end of the cylinder 4. The clamp 62 is installed at one end of the installation head 61. A rod 63 is fixedly connected to the end of the clamp 62 near the installation head 61. The rod 63 is inserted into the installation head 61. A positioning hole 65 is opened on the surface of the rod 63. A limit plate 66 is fixedly connected to the surface of the installation head 61. A pressure frame 64 is slidably connected inside the limit plate 66. A moving plate 67 is fixedly connected inside the pressure frame 64. A positioning rod 68 is fixedly connected to the upper end of the moving plate 67.

[0023] Specifically, the positioning rod 68 is inserted into the positioning hole 65, and the sliding rod 69 is fixedly connected inside the pressure frame 64.

[0024] In this embodiment: by setting the positioning rod 68, the insertion rod 63 can be limited, which reduces the possibility that the insertion rod 63 may easily detach from the installation head 61 during use, making it difficult to stabilize the clamp 62.

[0025] Specifically, a first spring 610 is sleeved and connected to the surface of the slide rod 69.

[0026] Specifically, one end of the first spring 610 is fixedly connected to the inside of the pressure frame 64, and the other end of the first spring 610 away from the pressure frame 64 is fixedly connected to the surface of the limiting plate 66. The first spring 610 is provided to facilitate the application of a reset spring force to the pressure frame 64.

[0027] In this embodiment: An auxiliary component 7 is fixedly installed at the lower end of the grinder 5. The auxiliary component 7 includes a protective cover 71 and a mounting ring 72. The mounting ring 72 is fixedly connected to the lower end of the grinder 5. The protective cover 71 is installed below the grinder 5. The protective cover 71 is made of rubber. A connecting ring 73 is fixedly connected to the upper end of the protective cover 71. The connecting ring 73 is inserted into the interior of the mounting ring 72. A pull hole 75 is opened on the surface of the mounting ring 72. An insert plate 74 is slidably connected inside the pull hole 75. One end of the insert plate 74 is inserted into the interior of the connecting ring 73. A limit rod 76 is fixedly connected inside the insert plate 74.

[0028] In this embodiment: by setting a protective cover 71, the waste material from grinding can be blocked, reducing the likelihood of waste material splashing everywhere when the equipment is in use.

[0029] Specifically, the limiting rod 76 is slidably connected inside the pull hole 75, and a second spring 77 is sleeved and connected to the surface of the limiting rod 76.

[0030] Specifically, one end of the second spring 77 is fixedly connected to the inside of the insert plate 74, and the other end of the second spring 77 away from the insert plate 74 is fixedly connected to the inside of the mounting ring 72. The second spring 77 is provided to facilitate the application of a reset spring force to the insert plate 74.

[0031] Working principle: When using the equipment, the user places the material to be ground on the upper surface of the base 1. Then, the cylinder 4 is activated to drive the clamp 62 to clamp the material. The moving arm 3 is then activated to drive the grinder 5 to rotate, and the grinder 5 grinds the surface of the material. When grinding different materials, the clamp 62 needs to be replaced. When replacing the clamp 62, the user presses down on the pressure frame 64, causing the moving plate 67 and the slide rod 69 to move inside the limiting plate 66. When the pressure frame 64 moves, it compresses the first spring 610 to generate elastic force. When the moving plate 67 moves, it drives the positioning rod. The 68 moves away from the positioning hole 65 on the surface of the insertion rod 63, and then the insertion rod 63 is freed from restraint, allowing the clamp 62 to be replaced. By setting the replacement device 6, the clamp 62 can be effectively replaced, thus reducing the need to replace the corresponding model of clamp 62 when clamping different types of materials. Generally, the clamp 62 is fixed to the mounting head 61 with bolts. The installation and removal of bolts are too cumbersome, resulting in low replacement efficiency for users. This replacement device 6 enables quick replacement of the clamp 62, improving the user's replacement efficiency.

[0032] When installing the protective cover 71, the user pulls the insert plate 74 to move it on the surface of the moving rod inside the pull hole 75. The movement of the insert plate 74 causes the second spring 77 to deform and generate elastic force. When the insert plate 74 moves, it inserts the connecting ring 73 at the upper end of the protective cover 71 into the interior of the mounting ring 72. After releasing the insert plate 74, the second spring 77 returns to its original position, causing the insert plate 74 to move and limit the insertion inside the connecting ring 73. By setting the auxiliary component 7, the protective cover 71 is effectively installed, thus achieving the purpose of installing the protective cover 71. This reduces the situation where, when the grinder 5 grinds the material on the surface of the clamp 62, the waste material from grinding is easily carried around by the grinder 5 and splashes everywhere, polluting the environment around the equipment. This auxiliary component 7 blocks the waste material from grinding, making it easier to collect and discharge the waste material, thus improving the practicality of the equipment.
