Description

A positioning mechanism for processing safety valves Technical Field

[0001] This utility model relates to the field of safety valve processing technology, and in particular to a positioning mechanism for safety valve processing. Background Technology

[0002] A safety valve is an important device that can automatically release overpressure media in a system to ensure the safe operation of equipment and pipelines. During the manufacturing process of a safety valve, it is necessary to accurately position the safety valve to ensure the accuracy and quality of subsequent processing steps.

[0003] Existing positioning mechanisms for safety valve processing are mostly uncommon and lack corresponding buffer components. They are only applicable to safety valves of specific specifications and cannot meet the positioning requirements of safety valves of various specifications. Therefore, we propose a positioning mechanism for safety valve processing to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a positioning mechanism for processing safety valves, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A positioning mechanism for processing a safety valve includes a processing table. A translation mechanism is fixedly installed on the outer surface of the processing table. Two fixed plates are fixedly installed on the upper surface of the translation mechanism. An electric push rod is fixedly installed on the outer surface of each fixed plate. An installation plate is fixedly installed at the output end of each electric push rod. A pressure sensor and a set of springs are fixedly installed on the outer surface of each installation plate. A clamping plate is fixedly installed at one end of each set of springs. Two sliding holes are formed on the outer surface of each installation plate. A protective pad and two limiting rods are fixedly installed on the outer surface of each clamping plate. Each limiting rod is slidably connected to the sliding hole.

[0007] In a further embodiment, a vertical plate is fixedly installed on the upper surface of the processing table, and a controller is fixedly installed on the outer surface of the vertical plate.

[0008] In a further embodiment, the upper surface of the processing table has two strip-shaped openings and two sliding grooves.

[0009] In a further embodiment, the translation mechanism includes two load-bearing plates and a moving block. Each load-bearing plate has a bearing fixedly embedded on its outer surface. The inner rings of the two bearings are jointly fixedly mounted with a lead screw. The outer surface of the moving block has a threaded hole, and the lead screw is threadedly connected to the threaded hole.

[0010] In a further embodiment, a chassis is fixedly mounted on the outer surface of one of the load-bearing plates, a servo motor is fixedly mounted on the inner wall of the chassis, the output end of the servo motor is fixedly mounted to one end of a lead screw, and a heat dissipation window is fixedly embedded on the outer surface of the chassis.

[0011] In a further embodiment, two support frames are fixedly installed on the outer surface of the movable block. The top of each support frame extends through a strip-shaped opening to the top of the processing table. A positioning table is fixedly installed on the top of the two support frames. Two sliders are fixedly installed on the bottom surface of the positioning table. Each slider is slidably connected to a groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device installs electric push rods on the outer surface of each fixed plate and mounting plates on the output end of each electric push rod. This allows the output end of each electric push rod to move and adjust the position of the mounting plate, spring, and clamping plate, thus facilitating the secure clamping of safety valves of different specifications. By installing protective pads on the outer surface of each clamping plate and pressure sensors on the outer surface of each mounting plate, damage to the outer surface of the safety valve by the clamping plates can be effectively prevented.

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] 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.

[0023] Please refer to Figures 1-5. In this utility model, a positioning mechanism for processing a safety valve includes a processing table 2. A translation mechanism 1 is fixedly installed on the outer surface of the processing table 2. Two fixing plates 7 are fixedly installed on the upper surface of the translation mechanism 1. An electric push rod 5 is fixedly installed on the outer surface of each fixing plate 7. An installation plate 16 is fixedly installed at the output end of each electric push rod 5. A pressure sensor 15 and a set of springs 13 are fixedly installed on the outer surface of each installation plate 16. A clamping plate 14 is fixedly installed at one end of each set of springs 13. Two sliding holes 12 are formed on the outer surface of each installation plate 16. A protective device is fixedly installed on the outer surface of each clamping plate 14. The device includes a pad 6 and two limiting rods 11, each of which is slidably connected to a sliding hole 12. The output end of each electric push rod 5 extends to move the mounting plate 16 and the pressure sensor 15. When each mounting plate 16 moves, it can move the clamping plate 14 via a spring 13. The two clamping plates 14 can quickly and securely hold the safety valve. The protective pad 6 installed on the outer surface of the clamping plate 14 can protect the outer surface of the clamping plate 14. When the two clamping plates 14 gradually squeeze the safety valve, each set of springs 13 will contract. When each clamping plate 14 squeezes the pressure sensor 15, the squeezing force of the two clamping plates 14 on the safety valve can be accurately measured.

[0024] A vertical plate 3 is fixedly installed on the upper surface of the processing table 2, and a controller 4 is fixedly installed on the outer surface of the vertical plate 3. Two slots 10 and two grooves 9 are opened on the upper surface of the processing table 2. The vertical plate 3 supports the controller 4. The operator can control the extension and retraction of the output ends of the two electric push rods 5 through the controller 4. The extrusion pressure value detected by the two pressure sensors 15 can be transmitted to the controller 4. By opening two slots 10 and two grooves 9 on the upper surface of the processing table 2, the translation mechanism 1 can be kept stable during movement.

[0025] The translation mechanism 1 includes two load-bearing plates 101 and a moving block 103. Each load-bearing plate 101 has a bearing 105 fixedly embedded on its outer surface. A lead screw 102 is fixedly mounted on the inner ring of both bearings 105. A threaded hole 110 is formed on the outer surface of the moving block 103, and the lead screw 102 is threadedly connected to the threaded hole 110. The two bearings 105 together support the lead screw 102. By threading the lead screw 102 to the threaded hole 110, the rotation of the lead screw 102 can drive the moving block 103 to move. A housing 107 is fixedly mounted on the outer surface of one of the load-bearing plates 101. A servo motor 109 is fixedly mounted on the inner wall of the housing 107. The output end of the servo motor 109 is fixedly mounted to one end of the lead screw 102. A diffuser is fixedly embedded on the outer surface of the housing 107. The heat window 108 and the chassis 107 can protect the servo motor 109. The servo motor 109 can provide rotation power for the lead screw 102. Two support frames 104 are fixedly installed on the outer surface of the moving block 103. The top of each support frame 104 passes through the strip opening 10 and extends to the top of the processing table 2. The top of the two support frames 104 are fixedly installed with a positioning table 106. Two sliders 8 are fixedly installed on the bottom surface of the positioning table 106. Each slider 8 is slidably connected to the slide groove 9. When the moving block 103 moves, it can drive the positioning table 106 to move through the two support frames 104. By installing two sliders 8 on the bottom surface of the positioning table 106 and making the two sliders 8 slidably connected to the two slide grooves 9 respectively, the positioning table 106 can remain stable during the movement.

[0026] The working principle of this utility model is as follows:

[0027] First, the operator controls the extension of the output ends of the two electric push rods 5 through the controller 4. The extension of the output end of each electric push rod 5 drives the installation plate 16, spring 13, pressure sensor 15 and clamping plate 14 to move. When the outer surface of the protective pad 6 installed on the outer surface of each clamping plate 14 comes into contact with the outer surface of the safety valve, each clamping plate 14 can reverse the pressure of the spring 13 and pressure sensor 15. After being compressed, each pressure sensor 15 can transmit the detected pressure value to the controller 4. When the compressive force detected by the pressure sensor 15 is greater than the preset value, the controller 4 can automatically close the two electric push rods 5. At this time, the two clamping plates 14 can clamp the safety valve tightly.
