Description

Technical Field

[0001] This utility model relates to the field of solenoid valve processing, specifically a low-temperature solenoid valve processing fixture. Background Technology

[0002] A solenoid valve is a device that uses electromagnetic force to control fluid flow. It is widely used in industrial automation fields, such as nuclear industry, aerospace industry, military industry, shipbuilding, petrochemical industry, power equipment, food machinery and other automatic control systems.

[0003] During the manufacturing process of solenoid valves, different processing requirements may necessitate external or internal clamping. Current fixtures may not be able to meet the requirements of both internal and external clamping simultaneously, leading to the need to change fixtures during the manufacturing process and affecting efficiency. Utility Model Content

[0004] To overcome the above-mentioned shortcomings, this utility model provides a low-temperature solenoid valve processing fixture.

[0005] The technical solution adopted by this utility model is as follows:

[0006] A low-temperature solenoid valve machining fixture includes a machining table with legs fixedly connected to the four corners of its bottom. Two sliding grooves are formed on the front and rear sides of the top of the machining table, symmetrically distributed. A slider slides are slidably engaged within the grooves. A clamping plate is fixedly connected to the top of the slider. The two clamping plates on the front and rear sides extend towards each other, with right-angled grooves formed at opposite ends of the left and right clamping plates. Internal support columns are vertically fixed to the two opposite corners of the top of the left and right clamping plates. A fixing column is fixedly connected to the center of the bottom of the slider. A worm gear is located between the two fixing columns, and a spindle is fixedly connected to the top of the worm gear. The spindle is located inside the bottom of the machining table, with bearings embedded within it. The outer wall of the spindle is fixedly fitted with bearings, and the spindle passes through the bearings... The bottom of the machining table is rotatably connected to the worm gear. Two fixed posts are vertically fixed to the bottom of the worm gear. The two fixed posts are close to the bottom edge of the worm gear and are centrally symmetrical about the center of the worm gear. There is a connecting rod between the fixed posts and the adjacent fixed posts. The two ends of the connecting rod are rotatably connected to the fixed posts and the fixed posts respectively. There is a worm on the front side of both worm gears. The right end of the worm is fixedly connected to the connecting shaft. The outer walls of both ends of the worm and the outer wall of the right end of the connecting shaft are rotatably sleeved with fixed plates. The top of each fixed plate is fixedly connected to the bottom of the machining table. The worm meshes with the worm gear. The right end of the connecting shaft is fixedly connected to bevel gears. A linkage drive mechanism is installed on the bottom right side of the machining table. The linkage drive mechanism meshes with the two bevel gears.

[0007] The linkage drive mechanism includes three fixed plates, which are distributed front and rear. The bottom of the fixed plates are rotatably connected to the drive shaft. The front and rear outer walls of the drive shaft are fixedly connected to bevel gears. The two bevel gears mesh with the two bevel gears respectively. The front end of the drive shaft extends out of the front side of the processing table, and the front end of the drive shaft is fixedly connected to the throttle.

[0008] The beneficial effects of this utility model are:

[0009] This utility model adopts a dual-station design, with four clamping plates that can simultaneously hold two solenoid valves, improving work efficiency and reducing the auxiliary time for processing a single solenoid valve.

[0010] Not only can the solenoid valve be centered and clamped using the clamping grooves on the clamping plate to achieve external clamping, but it can also be restricted by the internal support top column pressing against the inner wall of the solenoid valve to achieve internal clamping. This combination of internal and external clamping methods has higher adaptability.

[0011] The transmission method using worm gears and bevel gears has a large transmission ratio and can achieve a self-locking function, ensuring that the clamp will not loosen on its own even when subjected to a certain external force after clamping the solenoid valve, thus improving the reliability of clamping.

[0018] like Figure 1-5As shown: A low-temperature solenoid valve machining fixture includes a machining table 1, with support legs 2 fixedly connected to the four corners of the bottom of the machining table 1; two sliding grooves 3 are opened on the front and rear sides of the top of the machining table 1, and the two sliding grooves 3 on the same side are symmetrically distributed left and right, with a slider 4 slidingly engaged inside the sliding groove 3; a clamping plate 5 is fixedly connected to the top of the slider 4; the two clamping plates 5 on the same side extend towards each other; a clamping groove 6 is opened at the opposite end of the left and right clamping plates 5, and the clamping groove 6 is right-angled; an inner support column 7 is vertically fixedly connected to the two opposite corners of the top of the left and right clamping plates 5; a fixing column 8 is fixedly connected to the middle of the bottom of the slider 4; a worm gear 9 is located between the left and right fixing columns 8; a main shaft 10 is fixedly connected to the top of the worm gear 9; the main shaft 10 is inside the bottom of the machining table 1; a bearing 11 is embedded inside the bottom of the machining table 1; the bearing 11 is fixedly sleeved on the outer wall of the main shaft 10; the main shaft 10 is connected to the machining table 10 through the bearing 11. The bottom of the platform 1 is rotatably connected to two fixed posts 12 vertically fixed to the bottom of the worm gear 9. The two fixed posts 12 are close to the bottom edge of the worm gear 9 and are centrally symmetrically distributed with the center of the worm gear 9 as the origin. There is a connecting rod 13 between the fixed posts 12 and the adjacent fixed posts 8. The two ends of the connecting rod 13 are rotatably connected to the fixed posts 12 and 8 respectively. There is a worm 15 on the front side of each worm gear 9. The right end of the worm 15 is fixedly connected to the connecting shaft 16. The outer walls of both ends of the worm 15 and the outer wall of the right end of the connecting shaft 16 are rotatably sleeved with the fixed plate 14. The top of each fixed plate 14 is fixedly connected to the bottom of the processing platform 1. The worm 15 meshes with the worm gear 9. The right end of the connecting shaft 16 is fixedly connected to the bevel gear 17. A linkage drive mechanism is installed on the bottom right side of the processing platform 1. The linkage drive mechanism meshes with the two bevel gears 17.

[0019] The linkage drive mechanism includes a second fixed plate 18, three fixed plates 18 are distributed front and rear, and the bottom of the fixed plates 18 are rotatably connected to a drive shaft 19. The front end and rear end outer walls of the drive shaft 19 are fixedly connected to bevel gears 20. The two bevel gears 20 mesh with two bevel gears 17 respectively. The front end of the drive shaft 19 extends out of the front side of the processing table 1, and the front end of the drive shaft 19 is fixedly connected to a throttle 21.

[0020] Place the cryogenic solenoid valve to be processed on the processing table 1, positioning it between the two clamping plates 5 on the left and right.

[0021] The operator turns the throttle 21, which drives the transmission shaft 19 to rotate. The rotation of the transmission shaft 19 will drive the two bevel gears 20 to rotate synchronously, which in turn drives the two bevel gears 17 to rotate.

[0022] The rotation of bevel gear 17 drives the connecting shaft 16, which is fixedly connected to it, to rotate. The connecting shaft 16 drives the worm 15 to rotate. Because the worm 15 meshes with the worm wheel 9, the rotation of the worm 15 will drive the worm wheel 9 to rotate.

[0023] When the worm gear 9 rotates, it drives the fixed column 8 to move through the connection between the fixed column 2 12 and the connecting rod 13. The fixed column 8 then drives the slider 4 to slide in the slide groove 3. The two sliders 4 on the same side move towards the middle synchronously, thereby driving the clamping plate 5 to move towards the middle.

[0024] The two clamping plates 5 move relative to each other, and the clamping groove 6 contacts and clamps the outer wall of the solenoid valve to achieve external clamping.

[0025] When the outer wall of the solenoid valve needs to be machined, first tighten the two clamping plates 5 together, put the solenoid valve on the outside of the four inner support top columns 7, and rotate the handle 21 in the opposite direction so that the two clamping plates 5 move in opposite directions. The inner support top columns 7 press against the inner wall of the solenoid valve to achieve inner clamping.

[0026] Once the solenoid valve is stably clamped, it can be processed on the machining table 1.

[0027] After processing, turn the handle 21 in the opposite direction according to the clamping method. By reversing the above transmission process, the clamping of the solenoid valve is released, and then the processed solenoid valve is removed from the processing table 1.
