Description

Technical Field

[0001] This utility model relates to the field of automatic drain valve processing technology, and in particular to a disassembly and positioning structure for an automatic drain valve of a hydraulic press. Background Technology

[0002] In the MLCC industry production process, the automatic drain valve of the hydraulic press is a key mechanical sealing device used to ensure the normal drainage and sealing performance of the hydraulic press equipment. Its operational stability directly affects the working efficiency and product quality of the hydraulic press. When disassembling and assembling the automatic drain valve of a hydraulic press, a special positioning fixture is required to engage with the positioning hole on the drain valve. Force is applied through the fixture to lock and unlock the drain valve. Existing drain valve positioning primarily uses a positioning pin with a positioning hole, typically a double-hole design. While this method is simple and convenient and provides basic positioning, the positioning pin and the positioning hole on the fixture can slide relative to each other. This causes the fixture to easily shift or wobble during force application, resulting in poor stability during disassembly and assembly, and increasing the difficulty of the operation.

[0003] Furthermore, while the two-hole positioning ensures that rotation does not occur, unbalanced external forces often occur during disassembly and assembly, easily causing uneven stress on the two positioning holes. After long-term use, the positioning holes may deform due to uneven stress, making subsequent disassembly and assembly operations difficult and affecting equipment maintenance efficiency.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0024] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0025] The first aspect of this utility model is as follows: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, because the positioning pins and positioning holes on the fixture can slide relative to each other, the fixture is prone to displacement and shaking during the application of force, resulting in poor stability during disassembly and assembly and increasing the difficulty of the operation. Therefore, this utility model designs a novel positioning structure.

[0026] Specifically, a positioning hole 102 is provided at the end of the drain valve body 101. A positioning fixture 103 is also provided for positioning the drain valve body 101. A positioning post 104 is fixedly connected to the inner side of the positioning fixture 103. The diameter of the positioning post 104 is the same as the inner diameter of the positioning hole 102, and their positions correspond. Multiple positioning holes 102 are provided, arranged at equal angles around the central axis of the drain valve body 101. The number of positioning posts 104 is the same as the number of positioning holes 102, and their positions also correspond one-to-one. The outer edge of the positioning post 104 has a rounded chamfer.

[0027] Preferably, three positioning holes 102 and positioning posts 104 are provided.

[0028] By setting multiple positioning holes 102 and multiple positioning posts 104 of the same number and corresponding positions, the drain valve body 101 and the positioning fixture 103 can remain stable during disassembly and assembly, while achieving uniform force distribution.

[0029] The second aspect of this utility model is as follows: Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, to ensure a secure connection, a cylindrical groove is provided inside the positioning post 104. A clamping mechanism is installed inside the cylindrical groove.

[0030] The positioning post 104 has a through groove 107 on its side wall that passes through the cylindrical groove and the outside. The through groove 107 can be provided with a retractable clamping block 108. The clamping mechanism clamps the positioning post 104 by pushing the clamping block 108 out and abutting against the inner wall of the positioning hole 102.

[0031] Specifically, the clamping mechanism includes a sliding push head 112, which is slidably connected to the cylindrical groove inside the positioning post 104, and has an arc-shaped chamfer at its front edge. A connecting post 111 is fixedly connected to the upper end of the sliding push head 112, and the connecting post 111 has threads that are threadedly connected to the positioning fixture 103. An internal hexagonal cap 106 is fixedly connected to the upper end of the connecting post 111, and the positioning fixture 103 has an opening slot 105, with the internal hexagonal cap 106 located in the opening slot 105.

[0032] The clamping mechanism uses a threaded connecting post 111 to push the sliding pusher 112 forward, thereby pushing the clamping block 108 out. The connecting post 111 is connected to an internal hexagonal cap 106 and can be easily operated with a hexagonal wrench. A reset structure is also provided between the clamping block 108 and the inner wall of the cylindrical groove, which can automatically reset after the sliding pusher 112 retracts, making it easy to remove the positioning post 104 from the positioning hole 102.

[0033] In addition, the cross-section of the clamping block 108 is a right trapezoid, with the flat part located in the through groove 107 and the inclined part located in the cylindrical groove inside the positioning post 104, and the top of the inclined part is flush with the inner wall of the cylindrical groove.

[0034] Therefore, positioning is achieved by setting a positioning post 104 and a positioning hole 102. The side wall of the positioning post 104 is provided with a retractable clamping block 108, and a clamping mechanism is provided inside the positioning post 104 to push the clamping block 108 out. The clamping mechanism clamps the positioning post 104 by pushing the clamping block 108 out and pressing it against the inner wall of the positioning hole 102. This ensures that the positioning post 104 is firmly fixed inside the positioning hole 102, guaranteeing connection stability.

[0035] In summary, this utility model uses a positioning post 104 and a positioning hole 102 for positioning. The side wall of the positioning post 104 is provided with a retractable clamping block 108, and a clamping mechanism is provided inside the positioning post 104 to push the clamping block 108 out. The clamping mechanism clamps the positioning post 104 by pushing the clamping block 108 out and pressing it against the inner wall of the positioning hole 102. This ensures that the positioning post 104 is firmly fixed inside the positioning hole 102, guaranteeing connection stability. The clamping mechanism uses a threaded connecting post 111 to push the sliding push head 112 inward, thereby pushing the clamping block 108 outward. The connecting post 111, connected to an internal hexagonal cap 106, can be easily operated with a hexagonal wrench. A reset structure is also provided between the clamping block 108 and the inner wall of the cylindrical groove, which automatically resets after the sliding push head 112 retracts, facilitating the removal of the positioning post 104 from the positioning hole 102. By setting multiple positioning holes 102 and multiple positioning posts 104 of the same number and corresponding positions, the drain valve body 101 and the positioning fixture 103 can remain stable during disassembly and assembly, while achieving uniform force distribution.
