Description

Technical Field

[0001] This utility model relates to the field of manual valve technology, and in particular to a tooling fixture for machining the valve body of a manual valve. Background Technology

[0002] A manual rotary valve is a type of valve that controls fluid flow by manually turning a wheel. It is a common type of manual valve and is widely used in various fluid control systems, such as systems for conveying water, steam, gas, oil, and other liquids. The manual rotary valve controls the movement of the valve stem by turning the wheel, which in turn controls the opening and closing of the valve core, thereby controlling the flow of fluid.

[0003] A manual valve generally consists of a valve body, valve cover, valve core, valve stem, handwheel, and seals. During production, the valve body typically undergoes casting, cutting, and surface treatment. The cutting step requires the use of a machining fixture to hold and fix the valve body, ensuring its stability during processing.

[0004] Existing manual valve machining fixtures mainly use external clamps to hold the valve body surface. This clamping method results in a large space occupation, making it impossible to clamp multiple fixtures at the same time for machining, and is quite inconvenient to use. Utility Model Content

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Example 1

[0029] Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present utility model. This embodiment provides a processing fixture for a manual valve body 1, including a base plate 2. A plurality of valve bodies 1 are disposed on the upper surface of the base plate 2, a clamping assembly 3 is disposed below the valve body 1, and a positioning assembly 4 is disposed on the upper surface of the base plate 2.

[0030] The clamping assembly 3 includes a mounting plate 302 fixedly mounted on the upper surface of the substrate 2. A fixing seat 301 is fixedly connected to the upper surface of the mounting plate 302. A threaded sleeve 307 is movably connected inside the fixing seat 301. A lifting shaft 308 is engaged inside the threaded sleeve 307. Four clamping blocks 310 are slidably connected to the top of the lifting shaft 308. A plug-in block 311 is fixedly connected to the upper surface of the clamping block 310. An inclined surface is provided on the outer surface of the clamping block 310.

[0031] Specifically, a transmission rod 304 is movably connected inside the fixed base 301. A bevel gear 305 is fixedly connected to one end of the transmission rod 304 near the threaded sleeve 307. A bevel gear disk 306 that mates with the bevel gear 305 is fixedly connected to the outer surface of the threaded sleeve 307. A rotating block 303 is fixedly connected to one end of the transmission rod 304 away from the threaded sleeve 307. The arrangement of the transmission rod 304, bevel gear 305 and bevel gear disk 306 facilitates the rotation of the threaded sleeve 307.

[0032] Specifically, the upper surface of the fixed base 301 is provided with an inclined surface that cooperates with the outer surface of the clamping block 310. The outer surface of the fixed base 301 is fixedly connected with a limit sleeve 309. By setting the inclined surface on the upper surface of the fixed base 301, the inclined surface on the outer surface of the clamping block 310 can cooperate with the inclined surface on the upper surface of the fixed base 301, thereby driving the clamping block 310 to retract inward through the cooperation of the inclined surfaces.

[0033] Specifically, the outer surface of the lifting shaft 308 is provided with a limiting protrusion, the interior of the fixed seat 301 is provided with a limiting groove that mates with the limiting protrusion, the top of the lifting shaft 308 is provided with a limiting slide groove, and the lower surface of the clamping block 310 is fixedly connected with a limiting slider 312 that mates with the limiting slide groove. By setting the limiting protrusion and the limiting groove, the lifting shaft 308 is prevented from rotating with the rotation of the threaded sleeve 307. By setting the limiting slider 312 and the limiting slide groove, the clamping block 310 is normally retracted, preventing the clamping block 310 from shifting.

[0034] Furthermore, by rotating the rotating block 303 with other tools, the transmission rod 304 drives the bevel gear 305 to rotate. Through the cooperation between the bevel gear 305 and the bevel gear disc 306, the threaded sleeve 307 is rotated, thereby causing the lifting shaft 308 to descend within the threaded sleeve 307. When the lifting shaft 308 descends, it drives the clamping block 310 to cooperate with the inclined surface at the top of the fixed seat 301. Thus, the inclined surface on the outer surface of the clamping block 310 causes the clamping block 310 to retract, thereby tightening the plug-in block 311 and clamping the valve body 1. By clamping from the inside of the valve body 1, the external space occupied is reduced, thus enabling the simultaneous clamping of multiple valve bodies 1, which is convenient for processing.

[0035] Example 2

[0036] Reference Figure 1 , Figure 4 and Figure 5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The positioning component 4 includes a fixing block 401 fixedly installed on the upper surface of the substrate 2. Both ends of the fixing block 401 are hinged to a first rotating plate 402. The end of the first rotating plate 402 away from the fixing block 401 is hinged to a second rotating plate 403. The end of the second rotating plate 403 away from the fixing block 401 is hinged to a translation plate 404. The lower surface of the translation plate 404 is fixedly connected to a limit post 405. A spring 407 is provided between the first rotating plate 402 and the second rotating plate 403.

[0037] Specifically, both the lower surfaces of the first rotating plate 402 and the second rotating plate 403 have limiting grooves. A sliding plate 409 is slidably disposed inside the limiting groove. A hinge seat 408 is fixedly connected to the outer surface of the sliding plate 409. The sliding plate 409 is hinged to the limiting seat 406 through the hinge seat 408. A spring 407 is disposed between the two limiting seats 406. The limiting seats 406 limit the spring 407, ensuring that the spring 407 can be normally compressed and reset. Through the setting of the limiting block and the sliding groove, the limiting seat 406 can slide on the upper surface of the substrate 2, thereby preventing the first rotating plate 402 and the second rotating plate 403 from opening outward. When the first rotating plate 402 and the second rotating plate 403 rotate, the hinge seat 408 can slide on the lower surface of the first rotating plate 402 and the second rotating plate 403 through the setting of the limiting groove and the sliding plate 409, thereby ensuring the normal rotation of the first rotating plate 402 and the second rotating plate 403.

[0038] Specifically, rectangular openings are provided on both sides of the substrate 2 to cooperate with the limiting post 405. The rectangular openings limit the limiting post 405 and prevent it from rotating and misaligning.

[0039] Furthermore, the substrate 2 is placed at a designated position on the machine tool. The interior of the substrate 2 is fixed with bolts that can pass through the interior of the substrate 2 and thus be fixed with the threaded holes at the designated position on the machine tool. Then, the first rotating plate 402 and the second rotating plate 403 are pressed, thereby driving the translation plate 404 to move, thereby driving the insertion post to insert into the limiting hole at the designated position on the machine tool, thus realizing the installation of the substrate 2 and facilitating fixation. In addition, the mounting plates 302 on both sides can also limit the translation plate 404, thereby preventing the translation plate 404 from driving the fixing block 401 to rotate through the first rotating plate 402 and the second rotating plate 403.

[0040] Working principle: When machining the hand-operated valve body 1, the valve body 1 is inserted into the clamping block 310. The insertion block 311 is used to connect to the gap on the lower surface of the valve body 1. Then, the rotating block 303 is rotated by other tools, which drives the bevel gear 305 to rotate through the transmission rod 304. Through the cooperation between the bevel gear 305 and the bevel gear disc 306, the threaded sleeve 307 is rotated, which in turn drives the lifting shaft 308 to descend within the threaded sleeve 307. When the lifting shaft 308 descends, it drives the clamping block 310 to cooperate with the inclined surface at the top of the fixed seat 301. The inclined surface on the outer surface of the clamping block 310 causes the clamping block 310 to retract, thereby tightening the insertion block 311. The valve body 1 is clamped from the inside, reducing the external space occupied and allowing multiple valve bodies 1 to be clamped simultaneously for easier processing. After the valve body 1 is clamped, the base plate 2 is placed in the designated position on the machine tool. The base plate 2 is fixed inside by bolts that can pass through the inside of the base plate 2 and be fixed with the threaded holes in the designated position on the machine tool. Then, the first rotating plate 402 and the second rotating plate 403 are pressed, thereby driving the translation plate 404 to move, thereby driving the insertion post to be inserted into the limiting hole in the designated position on the machine tool, thus installing the base plate 2 for easy fixation, and finally completing the clamping and fixing of the hand-operated valve body 1.
