Description

Technical Field

[0001] The utility model relates to the field of fixture devices, in particular to a fixture for drilling inclined holes in a valve body. Background Art

[0002] The valve body is a main component in a valve. For valves with different uses, the structures and shapes of the valve bodies are also different. Multiple holes often need to be drilled on the valve body. During the manufacturing process, special fixtures are required. A fixture refers to a device used in the mechanical manufacturing process to fix the processing object, making it occupy the correct position to receive construction or inspection. A fixture for drilling inclined holes is a special fixing tool for processing inclined holes on the valve body. It is mainly used in the industrial field, especially when holes with inclined angles need to be processed.

[0003] Regarding the current fixtures for drilling inclined holes, the valve body is usually fixed by bolts. Often, a large number of bolts are required for fixing, and the process of repeatedly screwing the bolts is often needed during the fixing process. Such a fixing process may be rather cumbersome in actual operation, which may greatly reduce the efficiency of the fixing process. In addition, the inclined holes in the valve body may have variable angles. During the drilling process, the angle of the valve body often needs to be changed, and the fixing operation of the valve body may need to be repeated, which may greatly increase the complexity of the operation and may further reduce the efficiency of the hole-drilling operation.

[0004] Therefore, those skilled in the art have provided a fixture for drilling inclined holes in a valve body to solve the problems raised in the above background art. Summary of the Utility Model

[0037] Referring to Figures 1-5 , an embodiment provided by the present utility model: A valve body inclined hole drilling fixture includes an adjusting mechanism 1.

[0038] The fixture is provided with an adjusting mechanism 1. The adjusting mechanism 1 can horizontally adjust the position of the fixed valve body, and then adjust the opening position. The support base 101 supports the entire fixture, and a scale matching the clamping block 103 is provided at the upper end of the support base 101. The rotating mechanism 3 is moved according to the scale to ensure the clamping of the first vertical block 301 and the clamping block 103. The lifting table 102 is a platform that can automatically lift and is used to support the unfixed valve body block 4. Multiple grooves are provided at the upper end of the clamping block 103 and are clamped with the lower end of the first vertical block 301 to play a limiting role.

[0039] Fixed mechanisms 2 are provided on the opposite sides of the two rotating mechanisms 3. Each of the two fixed mechanisms 2 includes a vertical slide rod 204, a moving plate 203, and a right-angle block 208. Sliders 206 are slidably provided near the upper and lower ends of the two vertical slide rods 204.

[0041] The fixture is provided with a fixing mechanism 2. The fixing mechanism 2 can fix the valve body block 4 from both sides. The threaded rod 201 can move horizontally as it rotates with the thread. The fixing frame 202 can fix the fixing mechanism 2 on the rotating mechanism 3. The moving plate 203 can move as the threaded rod 201 moves. The vertical sliding rod 204 allows the slider 206 to slide up and down. The rotating rod 205 can rotate as the moving plate 203 moves. The up and down sliding of the slider 206 is driven by the rotation of the rotating rod 205. The connecting rod 207 combines the height of the right-angle block 208 with the height of the slider 206. The right-angle block 208 can just be clamped to the edge of the valve body block 4. The horizontal sliding rod 209 can replicate the sliding of the baffle 211. The rotation of the electric screw rod 210 can drive the movement of the baffle 211. The baffle 211 can fix the valve body block 4 from the front and rear ends;

[0042] On both sides near the upper end of the adjusting mechanism 1, there are rotating mechanisms 3 arranged. Both rotating mechanisms 3 include first vertical blocks 301. At the upper ends of the two first vertical blocks 301, there are second vertical blocks 302 fixedly arranged. On the opposite sides of the two first vertical blocks 301, there are motors 303 fixedly arranged. Inside the two first vertical blocks 301, there are small gears 304 rotatably arranged. Inside the two second vertical blocks 302, there are large gears 305 rotatably sleeved. On the opposite sides of the two second vertical blocks 302, there are threaded blocks 306 rotatably arranged. The lower ends of the two first vertical blocks 301 slide in the chute 104. The lower ends of the two first vertical blocks 301 are clamped with the clamping blocks 103. The output ends of the two motors 303 are respectively fixedly connected to the rotating shafts of the two small gears 304. The two large gears 305 are respectively meshed and connected with the two small gears 304;

[0043] The fixture is provided with a rotating mechanism 3. The rotating mechanism 3 can drive the fixing mechanism 2 to rotate and adjust the opening angle. The first vertical block 301 can drive the movement of the rotating mechanism 3 and at the same time fix the motor 303 and the small gear 304. The second vertical block 302 is connected to the first vertical block 301 to connect the upper and lower parts. The motor 303 provides power for the small gear 304. The rotation of the small gear 304 can drive the rotation of the large gear 305 through the meshing effect. One end of the threaded block 306 close to the large gear 305 is rotatably connected to the large gear 305. At the same time, the rotation of the threaded block 306 can drive the movement of the threaded rod 201.

[0044] Working principle: When using this fixture to fix the valve body block 4, first place the valve body block 4 on the upper end of the lifting table 102. Pull the handle 105 forward to release the clamping state between the clamping block 103 and the lower end of the first vertical block 301. Move the rotating mechanisms 3 on both sides until the right-angle block 208 moves to a suitable position. Then push the clamping block 103 backward until the clamping block 103 is clamped again with the lower end of the first vertical block 301;

[0045] Next, rotate the threaded block 306. Under the action of threaded rotation, the threaded rod 201 moves horizontally. Subsequently, the moving plate 203 moves away from the vertical sliding rod 204. Since the distance between the moving plate 203 and the vertical sliding rod 204 increases, the rotating rod 205 rotates, and the upper and lower sliders 206 slide towards the middle position. The right-angle blocks 208 connected by the connecting rod 207 are lifted and lowered synchronously until the valve body block 4 is clamped from the upper and lower ends. Then, start the electric lead screw 210. The baffle 211 moves back and forth as the electric lead screw 210 rotates until the baffle 211 clamps the valve body block 4 from the front and back ends. At this time, the fixing mechanism 2 fixes the valve body block 4 stably;

[0046] Finally, lower the lifting platform 102. At this time, the valve body block 4 is in a suspended state. Start the motor 303. The motor 303 can drive the rotation of the small gear 304. The small gear 304 can drive the rotation of the large gear 305 through meshing. The large gear 305 can drive the entire fixing mechanism 2 and the valve body block 4 to rotate through the fixing frame 202 until the valve body block 4 is adjusted to an appropriate angle.

[0047] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
