Abstract
Description
Technical Field
[0001] This invention belongs to the field of hydraulic valve processing technology, specifically a valve body processing equipment for mining explosion-proof hydraulic valves. Background Technology
[0002] Mining explosion-proof hydraulic valves are valves specifically designed for use in hydraulic systems in mines and environments with flammable and explosive properties. In these special environments, ordinary hydraulic valves may pose safety hazards such as fire and explosion, thus requiring special valves with explosion-proof capabilities to ensure the safe operation of the system. In existing technologies, hydraulic valves are typically manufactured using ordinary clamps to externally hold them in place for subsequent welding, cutting, and painting processes. However, due to the irregular curved surface of hydraulic valves, simply increasing the clamping force, while ensuring a certain degree of clamping tightness, can easily cause pressure damage to the surface, and the clamped area is difficult to process further. Therefore, it is necessary to provide a valve body processing equipment for mining explosion-proof hydraulic valves to solve the problems mentioned in the background technology. Summary of the Invention

[0010] Compared with the prior art, the beneficial effects of the present invention are:
[0011] This invention addresses the difficulty of positioning and clamping hydraulic valves during processing by employing a positioning and clamping mechanism to position and clamp the valve from inside, thus avoiding the limitations of external processing. At the same time, the soluble metal used is in close contact with the irregular surface of the hydraulic valve's inner wall under low-heat melting, ensuring a secure and tight clamping and preventing shaking during processing.

[0017] Please see Figure 1 In this embodiment of the invention, a mining explosion-proof hydraulic valve body processing equipment includes: a transmission frame 1, horizontally erected on the ground for horizontally transmitting hydraulic valves to be processed; a paint spraying box 11 is provided on one side of the transmission frame 1, which can uniformly spray paint on the surface of the hydraulic valve; a connecting rail 12 is horizontally erected above the transmission frame 1, and multiple drive seats 13 are slidably arranged on the connecting rail 12, each drive seat 13 is provided with a robotic arm 14, and a positioning and placement mechanism 2 is installed on the robotic arm 14. The positioning and placement mechanism 2 can extend into the irregular inner wall of the hydraulic valve and solidify the structure in the hydraulic valve, thereby avoiding the limited clamping of the outer wall of the hydraulic valve during subsequent surface processing and improving processing efficiency; the main body of the connecting rail has a ring structure, so that multiple robotic arms can cyclically rotate and pick up each hydraulic valve.
[0018] In this embodiment, the positioning and placement mechanism 2 includes: a rotating seat 21, which is installed at the end of the robotic arm 14. A drive shaft 22 is rotatably mounted on the rotating seat 21. An internal fixing component 23 and an external fixing component 3 are respectively mounted on the drive shaft 22. A telescopic adjustment component is provided between the internal fixing component 23 and the external fixing component 3. That is to say, the internal fixing component and the external fixing component can be correspondingly fixed and clamped from the inside of the hydraulic valve from above and below, thereby improving the clamping stability.
[0019] In a preferred embodiment, a baffle plate is slidably provided on the drive shaft 22 around both the built-in mounting component 23 and the external mounting component 3. The two baffle plates can limit the upper and lower positions of the built-in mounting component and the external mounting component, ensuring that both the built-in mounting component and the external mounting component are fixed in position within the hydraulic valve.
[0020] In this embodiment, the built-in mounting assembly 23 and the external mounting assembly 3 have the same structure and both include: a mounting bearing 31, with a bearing tube bearing 32 coaxially fixed below it. The bearing tube bearing 32 has multiple circumferentially distributed mounting plates 34. Each mounting plate 34 has two sliding guides 37 fixed vertically. A hinge pin 33 is provided between each mounting plate 34 and the bearing tube bearing 32. The hinge pin 33 has an X-shaped cross-section, and positioning elements are connected to the upper and lower ends of one side of each hinge pin 33. The positioning member is slidably connected to the sliding guide 37. The lower end of the other side of the hinge member 33 is hinged to the shaft tube seat 32. A bushing 36 is slidably disposed on the shaft tube seat 32. The upper end of the other side of the hinge member 33 is hinged to the bushing 36. An elastic bladder 35 is sleeved on the frame plate 34. That is to say, the bushing can drive the hinge member to perform cross deformation during vertical sliding, so that each frame plate expands inside and outside the hydraulic valve so that the elastic bladder contacts the inner wall of the hydraulic valve.
[0021] In this embodiment, the elastic bladder 35 is filled with a soluble metal that can melt under low heat. A heating block is embedded in the frame plate 34. In particular, the soluble metal refers to a metal that can change from liquid to solid in a relatively low temperature range (below or close to room temperature) and melt back into liquid when heated. The synthetic metal that can melt and solidify under low heat depends on the composition and ratio of the alloy, such as: Tin-Lead Alloy: Tin-Lead Alloy is a common low-melting-point alloy, and its melting point is usually around 183°C (361°F), depending on the composition ratio of the alloy; Tin-Bismuth Alloy: The melting point range of Tin-Bismuth Alloy is between 138°C (280°F) and 230°C (446°F), depending on the alloy composition.
[0022] In this embodiment, a central shaft 4 is rotatably disposed in the shaft tube seat 32, an eccentric block 41 is sleeved and fixed on the central shaft 4, and a vibration block 42 is slidably disposed inside the shaft tube seat 32. A support spring is disposed between the vibration block 42 and the shaft tube seat 32, and a positioning disk 43 is fixed on the shaft tube seat 32. The vibration block 42 is in close contact with the positioning disk 43.
[0023] In a preferred embodiment, the contact surface between the vibration block 42 and the positioning disk 43 is configured as a one-way toothed surface structure. Especially when the soluble metal is in a liquid deformation state, the central shaft rotates continuously, causing the shaft tube seat to generate radial vibration through the eccentric block. The vibration block rotates continuously and is affected by the contact toothed surface of the positioning disk to perform axial vibration, thereby ensuring that the soluble metal is completely in contact with the inner wall of the hydraulic valve when it solidifies.
[0024] Specifically, for the positioning and clamping of hydraulic valves during processing, a robotic arm is used to clamp and secure each hydraulic valve on the transfer frame. The positioning and clamping mechanism can slide deep into the inner wall of the hydraulic valve and achieve full contact with the inner wall of the hydraulic valve under the heat-melting and solidification of soluble metal. This provides effective positioning and clamping in subsequent surface processing and avoids pressure damage to the contact surface of the hydraulic valve.
[0025] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
