Description
Technical Field
[0001] This invention relates to the field of drilling for valve heads, and particularly to a valve head machining apparatus. Background Technology
[0002] Reference Figure 1 and Figure 2 This invention provides a cast valve head, comprising a main body and two adjacent connectors. Each connector has a first through hole at its end. The main body is circular, and a side plate is wound around its periphery away from the connector connection end to form a positioning groove. The main body is connected to two supports, each support having a second through hole at its end. In related technologies, valve heads with irregular shapes are difficult to fix and thus difficult to position for drilling. Manual drilling is generally inefficient, produces inconsistent drilling quality, and is detrimental to production. Furthermore, it is difficult to detect leaks in the valve head, and the processing effect is also difficult to assess, leading to defective products entering the market and hindering its use. Summary of the Invention
[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a valve head processing device that simplifies the drilling process of the two sets of through holes in the valve head, improves processing efficiency, optimizes the method of detecting whether the valve head is a qualified product, and ensures production quality.
[0004] According to an embodiment of the present invention, a valve head processing device is used to process a valve head. The valve head includes a main body and two adjacently arranged connectors. The connectors communicate with the main body. An air outlet communicating with the connector is provided in a positioning groove. A first through hole is provided at the end of the connector. The main body is circular in shape. A side plate is arranged around the periphery of the main body away from the connecting end of the connector to form a positioning groove. Two support frames are connected to the main body. A second through hole is provided at the end of the support frame. The valve head processing device includes a base, a drilling device, and a detection device. The drilling device is connected to the base and includes a fixed seat, a positioning plate, and a second drilling assembly. A first positioning post and a fixing groove are provided on the side wall of the fixed seat. The first positioning post is located directly below the fixing groove. The positioning groove is inserted into the first positioning post to position and install the valve head. The side wall of the connector abuts against the groove wall of the fixing groove. The top of the fixing seat is connected to a first drilling assembly for machining the first through hole. The positioning plate is connected to the base and is located on the side of the fixing seat near the first positioning post. It is provided with two positioning holes. The side of the positioning plate facing the fixing groove is provided with a pressure block for pressing the valve head. The second drilling assembly is connected to the base and is located on the side of the positioning plate away from the fixing seat. The second drilling assembly includes a first cylinder and a motor. The motor is connected to and drives the drill bit. The first cylinder is used to drive the motor to move closer to or away from the fixing seat. The drill bit can pass through the positioning hole to position and machine the second through hole. The detection device is connected to the base and adjacent to the drilling device, and is used to detect whether the valve head is leaking air. The detection device includes a platform, a support frame, and a pressure measuring device. A second positioning post is provided on the top surface of the platform. The second positioning post is circular and has a channel that connects to the pressure measuring device. The support frame is connected to the top surface of the platform and has a third cylinder. The output end of the third cylinder is connected to a pressure plate, which is located directly above the second positioning post. The third cylinder drives the pressure plate to press the valve head. The pressure measuring device includes an air pump and an air pipe connected to the air pump. The air pipe is connected to an air guiding assembly, which has two air guiding ports.
[0005] The valve head processing equipment according to embodiments of the present invention has at least the following beneficial effects: For processing the first through hole, the valve head is positioned with the assistance of a positioning post and a fixing groove. The worker installs the main body on the positioning post, rotates the valve head so that the connector position faces upward, and snaps the connector into the fixing groove. The end face of the connector, i.e., the position to be drilled, always faces upward. Then, the positioning plate is driven towards the valve head by a second cylinder, and a pressure block abuts against the other side of the valve head, applying pressure to both the connector and the main body to clamp and fix the valve head as a whole. The first drilling assembly then performs the processing. For processing the second through hole, the worker positions the main body of the valve head along the periphery of the positioning post on the side plate. The end of the positioning post is recessed into a groove to precisely fit into the positioning groove, serving as a limiting and positioning installation function. The operation is convenient and the structure is simple. A drill bit passing through the positioning hole on the positioning plate is aligned with the end of the bracket, i.e., the position to be processed. The first driving member drives the second driving member closer to the fixing seat, and both drill bits begin drilling simultaneously at the bracket position. After processing is completed, the first driving member drives the second driving member, including the drill bit, away from the valve head to complete the processing. While ensuring drilling quality, this method significantly improves drilling efficiency, simplifies operations, saves labor costs, and meets production needs. It is understandable that the processing sequence for the first through hole and the second through hole is reversible and can be performed simultaneously, thereby improving processing efficiency, ensuring drilling quality, and meeting production requirements.
[0006] Workers position the vent valve head according to the positioning groove and positioning post, aligning the openings of the two connectors with the air inlet. The channel of the positioning post connects to the air outlet. Air pumped by the air pump enters the vent valve head through the air inlet, then flows into the channel through the air outlet. This connects to the air pressure measuring component, providing a direct view of the air pressure data. Workers can directly determine whether the vent valve head is leaking based on the air pressure data, thus inspecting product quality. This simplifies the inspection process, facilitates worker operation, improves inspection efficiency, and ensures accurate inspection data, thereby optimizing production.
[0007] According to some embodiments of the present invention, the base is connected to a fixing frame, the fixing frame including a vertical plate and a horizontal plate connected to the end of the vertical plate, the horizontal plate being located directly above the motor, and the output end of the first cylinder passing through the vertical plate and connected to the motor.
[0008] According to some embodiments of the present invention, the horizontal plate is connected to a second cylinder, the output end of the second cylinder is connected to the positioning plate, and is used to drive the positioning plate toward or away from the fixed base.
[0009] According to some embodiments of the present invention, the horizontal plate is connected to a limiting plate, the limiting plate is provided with a limiting hole, and the output end of the second cylinder passes through the limiting hole.
[0010] According to some embodiments of the present invention, a baffle is provided on the top of the positioning plate. The baffle is positioned opposite the fixing groove in the horizontal direction. The side of the baffle facing the fixing seat is arc-shaped and partially extends out of the positioning plate to prevent iron filings generated during drilling.
[0011] According to some embodiments of the present invention, the positioning plate is connected to a limiting rod, and when the pressure block abuts against and presses against the valve head, the end of the limiting rod abuts against the side wall of the fixing seat.
[0012] According to some embodiments of the present invention, the end of the limiting rod is fitted with an elastic sleeve.
[0013] According to some embodiments of the present invention, the compression block is an elastic rubber product.
[0014] According to some embodiments of the present invention, the air pressure measuring device further includes a housing, which is disposed adjacent to the platform. The surface of the housing is provided with an air pressure data indicator and an alarm light. A controller is disposed inside the housing and is electrically connected to the air pressure data indicator and the alarm light.
[0015] According to some embodiments of the present invention, the air pressure data indicator is connected to the channel via a conduit that passes through the bottom of the housing.

[0026] Reference Figure 1 and Figure 2A cast valve head 100 is provided, comprising a main body 110 and two adjacent connectors 130. Each connector 130 has a first through hole 131 at its end. The main body 110 is circular, and a side plate 101 is arranged around its periphery away from the connecting end of the connector 130 to form a positioning groove. Two supports 120 are connected to the main body 110, and each support 120 has a second through hole 121 at its end. In related technologies, the valve head 100 has an irregular shape, making it difficult to fix and thus position the drilling hole. Manual drilling is generally inefficient and produces inconsistent drilling quality, which is detrimental to production.
[0027] Therefore, refer to 1. Figure 2 and Figure 3 This invention provides a processing device for a stove valve head 100, comprising a base 600, a fixing seat 200, a positioning plate 300, and a second drilling assembly 400. The fixing seat 200 is connected to the base 600. The side wall of the fixing seat 200 is provided with a positioning post and a fixing groove 220. The fixing groove 220 is an arc-shaped groove that matches the connector 130. The positioning post is located directly below the fixing groove 220. The positioning groove is inserted into the positioning post to position and install the valve head 100. The side wall of the connector 130 abuts against the groove wall of the fixing groove 220. The top of the fixing seat 200 is connected to a first drilling assembly 230 for drilling a first through hole 131 in the connector 130. The positioning plate 300 is connected to the base 600 and is located on the side of the fixed seat 200 near the positioning post. The positioning plate 300 has two positioning holes, which are flush with the two brackets 120 on the horizontal line. A pressure block 320 is provided on the side of the positioning plate 300 facing the fixed groove 220 for pressing the valve head 100. The second drilling assembly 400 is connected to the base 600 and is located on the side of the positioning plate 300 away from the fixed seat 200. The second drilling assembly 400 includes a first cylinder 410 and a motor 420. Two motors 420 are provided, and both motors 420 are connected to and drive the drill bit 421. The first cylinder 410 is used to drive the motor 420 to move closer to or away from the fixed seat 200. The drill bit 421 can pass through the positioning hole to position and machine the second through hole 121.
[0028] Preferably, the pressure block 320 is made of elastic rubber to prevent excessive clamping force from damaging the main body 110 of the valve head 100.
[0029] Reference Figure 3It also includes a detection device, which comprises a platform 700, a support frame 720, and a pressure measuring device 740. A second positioning post 710, circular in shape, is mounted on the top surface of the platform 700 and has a channel connecting to the pressure measuring device 740. The support frame 720 is connected to the top surface of the platform 700 and is equipped with a third cylinder 721. The output end of the third cylinder 721 is connected to a pressure plate 730, which is located at the second... Directly above the positioning post 710, the third cylinder 721 drives the pressure plate 730 to press the valve head 100. The air pressure measuring device 740 includes an air pump and an air pipe 751 connected to the air pump. The air pipe 751 is connected to an air guide assembly 750. The air guide assembly 750 is provided with two air guide ports. When the second positioning post 710 is fitted into the positioning groove, the channel is connected to the air outlet. The two connectors 130 are connected to each other. When the air pump is turned on, the air pressure measuring device 740 measures whether the valve head 100 is leaking air. Understandably, workers position the valve head 100 according to the positioning groove and the second positioning post 710, align the openings 121 of the two connectors 130 with the air inlet, and connect the channel of the second positioning post 710 to the air outlet. Air pumped out by the air pump enters the valve head 100 through the air inlet, then enters the channel through the air outlet, connecting to the air pressure measuring component to directly obtain air pressure data. Workers can directly determine whether the valve head 100 is leaking based on the air pressure data, thus inspecting product quality. This simplifies the inspection process, facilitates worker operation, improves inspection efficiency, and ultimately optimizes production.
[0030] Refer to 1. Figure 2 and Figure 3 Understandably, for machining the first through hole 131, the valve head 100 is positioned with the assistance of the positioning pin and the fixing groove 220. The worker installs the main body 110 on the positioning pin, rotates the valve head 100 so that the connector 130 faces upward, and then snaps the connector 130 into the fixing groove 220. The end face of the connector 130, i.e., the position to be drilled, always faces upward. Then, the second cylinder 510 drives the positioning plate 300 to move towards the valve head 100, and the pressure block 320 abuts against the other side of the valve head 100, applying pressure to both the connector 130 and the main body 110, thus clamping and fixing the valve head 100 as a whole. The first drilling assembly 230 then performs the machining. This simplifies the positioning, assembly, and clamping steps of the valve head 100, improves drilling efficiency, enhances machining quality, and optimizes production.
[0031] Refer to 1. Figure 2 and Figure 3Furthermore, for machining the second through hole 121, the worker places the main body 110 of the valve head 100 along the periphery of the positioning post on the side plate 101. The end of the positioning post is recessed into a groove to fit precisely into the positioning groove, serving as a limit and positioning installation function. This is convenient to operate and has a simple structure. The drill bit 421, passing through the positioning hole on the positioning plate 300, is aligned with the end of the bracket 120, i.e., the position to be machined. The first driving component drives the second driving component closer to the fixed seat 200, and the two drill bits 421 begin drilling simultaneously at the position of the bracket 120. After machining is completed, the first driving component drives the second driving component, including the drill bit 421, away from the valve head 100 to complete the machining. While ensuring drilling quality, this greatly improves drilling efficiency, simplifies operation, saves labor costs, and meets production needs. It is understood that the machining sequence of the second through hole 121 for the first through hole 131 is reversible and can also be performed simultaneously, thereby improving machining efficiency, ensuring drilling quality, and meeting production needs.
[0032] Reference Figure 3 The base 600 is connected to a fixing frame 500, which includes a vertical plate 501 and a horizontal plate 502 connected to the end of the vertical plate 501. The horizontal plate 502 is located directly above the motor 420. The output end of the first cylinder 410 passes through the vertical plate 501 and is connected to the motor 420. The horizontal plate 502 is connected to a second cylinder 510, the output end of which is connected to a positioning plate 300 to drive the positioning plate 300 toward or away from the fixing base 200. The horizontal plate 502 is connected to a limiting plate 503, which has a limiting hole through which the output end of the second cylinder 510 passes. The fixing frame 500 is horizontally positioned above the second drive assembly and connected to the second cylinder 510. The second cylinder 510 drives the positioning plate 300 to complete the machining of the first through hole 131, improving drilling efficiency while maintaining a compact overall structure and optimizing usage. The vertical plate 501 itself serves to limit the movement of the first cylinder 410, preventing misalignment and damage when the first cylinder 410 drives the motor 420. Furthermore, the horizontal plate 502 is provided with a limit plate 503, which serves to limit and guide the second cylinder 510.
[0033] Reference Figure 3The baffle 310 is positioned horizontally opposite the fixing groove 220 to prevent iron filings generated during drilling. The side of the baffle 310 facing the fixing groove 220 is arc-shaped, and part of the baffle 310 extends beyond the positioning plate 300. Splashing iron filings during drilling creates additional cleaning pressure, affecting overall production efficiency, and the sharp filings also pose a safety hazard, potentially causing worker injury. When the positioning plate 300 moves and the pressure block 320 clamps the valve head 100 for processing, the baffle 310 is adjacent to the valve head 100. The arc-shaped baffle 310 precisely prevents iron filings generated during drilling, avoiding safety hazards and additional cleaning work caused by flying iron filings.
[0034] Reference Figure 3 It is understandable that the limiting rod 330 restricts the positioning plate 300 from moving further, thus serving a positioning function and preventing the positioning plate 300 from moving too far, causing excessive pressure on the valve head 100 from the pressure block 320, which could damage the valve head 100 or the positioning plate 300. Preferably, an elastic sleeve 331 is fitted at the end of the limiting rod 330 to provide a buffering effect and prevent excessive pressure on the fixed seat 200 from the limiting rod 330, which could damage the fixed seat 200.
[0035] Reference Figure 3 The barometric pressure measuring device 740 also includes a housing, which is adjacent to the platform 700. A barometric pressure data indicator 741 and an alarm light 742 are mounted on the surface of the housing. A controller is housed inside the housing and is electrically connected to the barometric pressure data indicator 741 and the alarm light 742. The barometric pressure data indicator 741 is connected to a channel via a conduit 752, which passes through the bottom of the housing. Workers can visually obtain barometric pressure data through the pointer and reading of the barometric pressure data indicator 741, simplifying judgment. Furthermore, the barometric pressure measuring device 740 has a simple overall structure and is easy to assemble.
[0036] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
