Description

Technical Field

[0001] This utility model relates to the field of mining chain technology, and in particular to a welding and deburring fixture for a high-strength, wear-resistant, mining butterfly chain. Background Technology

[0002] Mining chains are used as a supporting transmission medium in coal mine working face conveyors. They are widely used in various coal mine conveying equipment such as scraper conveyors and transfer conveyors, and are one of the most widely used spare parts in coal mine scraper conveyors.

[0003] Currently, there are two main types of mining chains: one is the high-strength round link chain, characterized by identical welded round links for both vertical and horizontal links, conforming to standard GB / T12718-2009 "High-strength Round Link Chains for Mining"; the other is the high-strength compact chain, characterized by welded round links for horizontal links and flat extruded / forged links for vertical links, conforming to standard MT / T929-2004 "High-strength Compact Chains for Mining". Compared to the simple chaining method of alternating links in round link chains, compact chains require bending and weaving using specialized chain-weaving molds. However, with technological advancements, chains have emerged, such as the one disclosed in invention patent application number US13143285. This chain has flat links that are approximately butterfly-shaped, and vertical links that are flat. By modifying the shape of the flat links, it adapts to the use of scrapers. However, due to the special structural form of butterfly chains, existing welding and deburring fixtures for mining chains can only be used for round link chains and compact chains, and cannot be used for welding butterfly chains. Summary of the Invention

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", "lower", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] Please refer to Figures 1 to 6 This utility model provides a high-strength, wear-resistant butterfly chain welding deburring fixture, including a positioning module 01, a support base 02, and a deburring part 04. The positioning module 01 includes a left positioning module 11 and a right positioning module 12. The left positioning module 11 and the right positioning module 12 can clamp the open vertical ring from both sides. The support base 02 is located between the left positioning module 11 and the right positioning module 12 and can provide support for the lower part of the open vertical ring. After welding is completed, the weld seam of the welded vertical ring can be deburred by the deburring part 04, so that multiple deburring operations can be performed with one clamping, ensuring the appearance quality of the chain.

[0029] In one embodiment, the ends of the left positioning mold 11 and the right positioning mold 12 have positioning grooves 13 that are adapted to the size and shape of the open vertical ring. When the open vertical ring is clamped from left to right by the left positioning mold 11 and the right positioning mold 12, the positioning grooves 13 can adapt to the outer contour of the open vertical ring to improve the stability of the clamping. The movement of the left positioning mold 11 and the right positioning mold 12 can be achieved by auxiliary equipment with telescopic function, such as hydraulic cylinders, electric telescopic rods, pneumatic telescopic rods, etc. This technology is prior art and will not be described in detail here.

[0030] In order to make better contact between the positioning groove 13 and the open vertical ring, the junction of the bottom surface and the side wall of the positioning groove 13 is designed to be arc-shaped.

[0031] To facilitate installation, mounting parts 14 are provided on the side of the left positioning mold 11 and the right positioning mold 12 away from the positioning groove 13, and the left positioning mold 11 and the right positioning mold 12 can be installed on the auxiliary equipment by means of bolts.

[0032] The left positioning mold 11 and the right positioning mold 12 have a supporting inclined surface 15 on the side facing the support base 02. The supporting inclined surface 15 can support the butterfly-shaped flat ring, so that the two butterfly-shaped flat rings are assembled with the open vertical ring in a V shape, so as to facilitate welding.

[0033] In one embodiment, the end of the support base 02 has a support groove 21 that is adapted to the size and shape of the open vertical ring.

[0034] In order to better enable the support groove 21 to make better contact with the open vertical ring, the junction of the bottom surface and the side wall of the support groove 21 is designed to be arc-shaped.

[0035] In one embodiment, the deburring section 04 includes a substrate 41 with a notch 42 through which an open vertical ring can pass. Deburring blades 43, adapted to the outer contour of the open vertical ring, are symmetrically arranged at the left and right ends of the notch 42. When welding burrs need to be removed, the substrate 41 is moved forward so that the rear deburring blades 43 contact the rear part of the welding vertical ring. The substrate 41 is then moved to the right positioning mold 12, allowing the upper deburring blades 43 to remove the welding burrs at the rear of the vertical ring. Subsequently, the substrate 41 is moved backward so that the front deburring blades 43 contact the front part of the welding vertical ring. The substrate 41 is then moved to the left positioning mold 11, allowing the front deburring blades 43 to remove the welding burrs at the front of the vertical ring. During the entire process of removing welding burrs, only the position of the deburring blade 43 needs to be adjusted to remove the burrs from the welded vertical ring. There is no need to adjust the position of the welded vertical ring, which greatly improves the removal efficiency. Moreover, the shape of the deburring blade 43 is adapted to the outer contour of the vertical ring cross section, which ensures the appearance quality of the chain when removing welding burrs.

[0036] The substrate 41 has a recess 44 on its front side facing the deburring blade 43 at the right end of the notch 42, and a recess 44 on its back side facing the deburring blade 43 at the left end of the notch 42. The recess 44 prevents the removed residue from splashing outwards during the removal of welding burrs.

[0037] In addition, bolt holes are provided on the substrate 41 to facilitate installation and disassembly, thereby allowing the substrate 41 to be easily mounted on the deburring equipment and controlling the position movement of the deburring part 04. This technology is prior art and will not be described in detail here.

[0038] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
