Description

Technical Field

[0001] This application relates to the field of valve casting technology, specifically a drilling fixture for casting valves. Background Technology

[0002] The development of valve casting technology is closely related to the needs of industrial automation, the importance of fluid control systems, the progress of materials science, and the demand for high-quality and high-performance valve products. Casting is one of the main processes for manufacturing valves. It involves heating metal to a molten state and then pouring it into a mold to cool and solidify. After solidification, the valve usually needs to be machined and drilled, so a drilling fixture for casting valves is required.

[0003] Chinese patent CN217192767U discloses a drilling fixture for casting valves, including a base body and a holding mechanism on the top of the base body. By setting the holding mechanism, a first rotary motor can drive a lifting plate to rise or fall, thereby moving the four holding heads closer or further apart, achieving stable holding of the valve and avoiding the problem of low drilling accuracy caused by valve displacement during drilling, thus effectively improving the work efficiency of valve processing.

[0004] However, during the use of the above-mentioned device, the clamping head is driven by the first rotary motor to clamp the valve. However, a large amount of dust and debris are generated when drilling the valve. If it is not cleaned in time, it is easy to accumulate in the gaps of the equipment and some sliding tracks, which can easily cause the drilling position to deviate and affect the quality of the drilling work. In view of this, we propose a drilling fixture for casting valves. Utility Model Content

The cleaning mechanism 2 is located inside the support frame 1, and the drilling mechanism 3 is located above the cleaning mechanism 2. The cleaning mechanism 2 includes a guide channel 202, a cleaning air outlet 206, and a dust collection cloth 210 for collecting dust generated during drilling. The guide channel 202 is located below the cleaning air outlet 206, and the cleaning air outlet 206 is used to blow dust into the interior of the guide channel 202. The dust collection cloth 210 is located below the guide channel 202, and the guide channel 202 is used to guide dust into the interior of the dust collection cloth 210.

[0031] When drilling holes in the valve, the dust and debris generated during drilling are cleaned and blown away through the cleaning air vent 206, then the dust and debris are guided through the guide channel 202, and finally collected through the dust collection cloth belt 210, thereby preventing dust and debris from affecting the stable operation of the equipment.

[0033] A collection trough 207 is fixedly installed at the bottom of the support frame 1. A sliding groove 208 is provided on one side of the collection trough 207. A sliding frame 209 is slidably connected inside the sliding groove 208. The interior of the sliding frame 209 is connected to the dust removal cloth belt 210.

The installation groove 211 is compatible with the fixing plate 212.

[0034] First, the valve to be processed is placed on the processing table 201 for drilling. Some dust or debris is generated during drilling. Then, the air pump 205 is started. The air pump 205 blows air through the cleaning air vent 206 at the output end. During cleaning, the baffle 203 on the processing table 201 helps to prevent debris from flying around. The dust and debris are then guided through the guide channel 202. The guided debris is then collected through the collection channel 207. The dust collection cloth 210 in the collection channel 207 facilitates the collection operation. Alternatively, the sliding frame 209 can be pulled to slide inside the slide groove 208, which facilitates the cleaning operation of the dust collection cloth 210 in the sliding frame 209. After cleaning, the sliding frame 209 can be retracted by the fixing plate 212. Then, the bolts on the fixing plate 212 are threadedly fastened to the mounting groove 211.

The clamping plate 5 is located above the processing table 201.

[0036] By activating the first hydraulic rod 4, the first hydraulic rod 4 drives the clamping plate 5 at the output end to fix the valve on the processing table 201, thereby preventing displacement during drilling.

[0037] Reference Figure 1 and Figure 4In one aspect of this embodiment, the drilling mechanism 3 includes a slide plate 301 fixedly installed on the top of the support frame 1. A slider 303 is slidably connected inside the slide plate 301. A second hydraulic rod 304 is fixedly installed on one side of the slider 303. An adjusting frame 305 is fixedly installed at the output end of the second hydraulic rod 304. A first motor 306 is fixedly installed inside the adjusting frame 305.

[0039] By activating the first motor 306, the drill bit 307 at the bottom of the adjusting frame 305 rotates. Simultaneously, by activating the second hydraulic rod 304, the adjusting frame 305 is raised and lowered, facilitating the drilling of the valve. When the position needs to be adjusted, the second motor 308 is activated, causing the threaded rod 302 to rotate inside the slide plate 301. The threaded rod 302, in conjunction with the slider 303, slides inside the slide plate 301, thereby driving the second hydraulic rod 304 to adjust.

[0040] All electrical devices in this plan are powered by an external power source.

[0041] Working principle: During use, the first hydraulic rod 4 drives the clamping plate 5 at the output end to fix the valve on the processing table 201. Then, the first motor 306 drives the drill bit 307 at the bottom of the adjusting frame 305 to rotate. At the same time, the second hydraulic rod 304 is activated, which drives the adjusting frame 305 to adjust its height, thus facilitating the drilling of the valve. Any dust or debris generated during drilling is cleared by activating the air pump 205, which blows air through the cleaning vent 206 at the output end. The baffle 203 on the processing table 201 helps to prevent debris from flying around, and the dust and debris are guided by the guide channel 202. Then, they are collected by the dust collection cloth 210 in the collection tank 207. Alternatively, the sliding frame 209 can be pulled to slide inside the slide 208, which facilitates the cleaning of the dust collection cloth 210 in the sliding frame 209. After cleaning, the sliding frame 209 can be retracted by the fixing plate 212, and then the bolts on the fixing plate 212 are threadedly fastened to the mounting groove 211.
