Description

Technical Field

[0001] The invention relates to the technical field of ginning wire welding tooling and equipment, in particular to a thorn roller welding tooling. Background Art

[0002] In 2020, my country's machine-picked cotton developed rapidly. Mechanized cotton planting widely adopts technologies such as mulching and new high-efficiency water-saving drips. Mechanical cotton picking will involve a large amount of foreign fibers such as plastic mulch and drip irrigation tape; while hand-picked cotton is easily mixed with foreign fibers such as hair, chemical fiber, and animal hair. In view of the fact that there are many foreign fibers in domestic cotton, and there are many hair and mulch fragments in cotton, various cotton machine manufacturers continue to optimize and improve new foreign fiber cleaning equipment. In the core principle of mainstream equipment, a dual-channel winding mechanism is used to continuously remove long three-wires such as drip irrigation tape and mulch.

[0003] The traditional method of distributing spikes on a spike roller is to draw lines on it, which takes too long to meet the needs of mass production. In addition, the angles of the spikes cannot be accurately guaranteed when they are placed and welded, whether in the circumferential direction or the horizontal axis direction. The welded roller spikes are not neat and time-consuming.

[0004] The technical problem to be solved by the present invention is: how to place the thorn roller without marking so that it can quickly weld the same row or two rows of thorns, and how to flip it after welding one row of thorns and weld the remaining rows of thorns, so as to quickly and efficiently weld the thorn roller, quickly realize the rapid positioning of the thorns on the thorn roller, and how to quickly realize the welding of the thorns on the entire thorn roller. Summary of the invention

[0005] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides a thorn roller supported by a slender welding base and two fixed end plates, and at the same time, a pair of symmetrical triangular protrusions are provided at the top of the U-shaped opening roller groove of the two fixed end plates, which are used to flexibly place the L-shaped left size mold and the L-shaped right size mold, and form a welding workbench in combination. The thorns are directly against multiple left and right support blocks arranged on the inner sides of the L-shaped left size mold and the L-shaped right size mold, eliminating the time for marking and the time for placing the angle, and then through the positioning pins and bearings fixed on the fixed end plates, the circumferential direction of the position is replaced, thereby improving the welding efficiency and quality of the thorn roller to form a welding tool for the thorn roller.

[0006] The technical solution adopted by the present invention is:

[0007] A welding tool for a spike roller, comprising a slender welding base,

[0008] The elongated welding base is provided with fixed end plates with U-shaped opening roller grooves at both ends for supporting the spike roller;

[0009] Each of the fixed end plates has a pair of symmetrical triangular protrusions on the top of its U-shaped opening roller groove, which are used to flexibly place the L-shaped left size mold and the L-shaped right size mold;

[0010] The inner sides of the L-shaped left size mold and the L-shaped right size mold relative to each other are respectively fixedly provided with a plurality of left leaning blocks and a plurality of right leaning blocks;

[0011] Each of the left supporting block and the right supporting block is provided with a left limiting groove and a right limiting groove facing the thorn roller, for inserting and positioning the thorns, so as to facilitate the limiting of the thorns when welding with the thorn roller.

[0012] Preferably, a pressing plate device is provided between at least two or more adjacent left leaning blocks and right leaning blocks;

[0013] The pressure plate device has one side tangent to the thorn nail of the left limiting groove of the left leaning block, and the other side tangent to the thorn nail of the right limiting groove of the right leaning block.

[0014] Preferably, the pressing plate device can be movably moved between the left leaning block and the right leaning block.

[0015] Preferably, the left limiting groove and the right limiting groove of the left leaning block and the right leaning block are both arc-shaped structures.

[0016] Preferably, the pressure plate device includes a left pressure plate, a right pressure plate and a plurality of baffles for connecting the left pressure plate and the right pressure plate.

[0017] Preferably, a support bearing is provided on both sides of the bottom of the U-shaped opening roller groove of each fixed end plate, and the support bearing extends toward the center direction of the spike roller.

[0018] Preferably, each of the fixed end plates is provided with a limiting plate on the outer side surface close to the triangular protrusion.

[0019] Preferably, each of the fixed end plates has at least one set of circumferential limiting components consisting of a retractable positioning pin and a retractable set screw in the axial direction toward the pricking roller.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The thorn roller welding tool of the present invention is composed of a slender welding base and an L-shaped left size mold and an L-shaped right size mold. The limit block limits the movement of the size position mold. After the winding roller is placed, the thorns lean against the left support block or the right support block. With the help of a pressure plate device, displacement during welding is prevented, thereby reducing the welding time of the thorn roller thorns.

[0022] The main advantages of this structure are: on the one hand, the thorns are accurately placed on the axial position of the thorn roller, distributed at intervals, and neat after welding, eliminating the marking work and improving work efficiency; on the other hand, the accuracy of the circumferential distribution of the thorns is guaranteed. As long as the thorns are close to the positioning pins, they are in one position, shortening the welding time.

[0023] In summary, the spike roller welding tool of the present invention reduces the preparation time for welding work and improves the accuracy and quality of welding. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] In order to deepen the understanding of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. The embodiments are only used to explain the present invention and do not limit the protection scope of the present invention.

[0032] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the combination or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, in the description of the embodiments of the present invention, the device positional relationships such as "up", "down", "front", "back", "left", "right" and the like in all the drawings are based on the positions or positional relationships shown in the accompanying drawings. Figure 1 As standard.

[0033] like Figure 1 As shown, a welding tool for a spike roller includes a slender welding base 1,

[0034] The elongated welding base 1 is provided with fixed end plates 10 with U-shaped opening roller grooves 101 at both ends, respectively, for supporting the pricking roller 9, so that the pricking roller 9 can be quickly placed into the U-shaped opening roller groove, or taken out;

[0035] Each of the fixed end plates 10 has a pair of symmetrical triangular protrusions 102 and 103 at the top of the U-shaped opening roller groove 101, which are used to flexibly place the L-shaped left size mold 2 and the L-shaped right size mold 3, so that the inner surfaces of the L-shaped left size mold 2 and the L-shaped right size mold 3 have a certain degree of inclination, which is convenient for placing the left support block 21 and the right support block 31 for positioning and for inserting and removing the welding device;

[0036] The inner sides of the L-shaped left size mold 2 and the L-shaped right size mold 3 facing each other are respectively fixedly provided with a plurality of left leaning blocks 21 and a plurality of right leaning blocks 31;

[0037] See Figure 2 As shown, each of the left support block 21 and the right support block 31 is provided with a left limiting groove 211 and a right limiting groove 311 facing the thorn roller 9, for inserting and positioning the thorn 5, so as to limit the position when the thorn 5 is welded to the thorn roller 9, so that the thorn 5 can be fixed in its predetermined position.

[0038] from Figure 2 It can also be clearly seen from the structural diagram that a pressing plate device 4 is provided between at least two or more adjacent left leaning blocks 21 and right leaning blocks 31 of the welding tool;

[0039] The pressure plate device 4 is tangent to the thorn nail 5 of the left limiting groove 211 of the left leaning block 21 on one side, and tangent to the thorn nail 5 of the right limiting groove 311 of the right leaning block 31 on the other side, thereby fitting and pressing the thorn nail to prevent it from shifting, and better realizing the welding positioning of the thorn nail 5.

[0040] contrast Figure 1 and Figure 3 As shown, the pressing plate device 4 of the welding tool can be movably moved between the left supporting block 21 and the right supporting block 31, so as to meet the welding of the spikes 5 within any length range of the spike roller 9, and only a shorter pressing plate is needed to complete the welding, which saves tooling and is flexible and convenient to use.

[0041] from Figure 2 and Figure 4 It can be seen that the left limiting groove 211 and the right limiting groove 311 of the left supporting block 21 and the right supporting block 31 of the welding tool are both arc-shaped structures, which can better fit the shape of the spike 5 and ensure the intact performance of its appearance during welding.

[0042] like Figure 2 As shown, the pressure plate device 4 of the welding tool includes a left pressure plate 41, a right pressure plate 42 and a plurality of baffles 43 for connecting the left pressure plate 41 and the right pressure plate 42. The setting of the baffles 43 can not only connect the left and right pressure plates, but also provide a gripping point for the movement of the entire pressure plate device 4, and has good convenience of use.

[0043] from Figure 5 and Figure 7 As can be seen in the figure, a support bearing 7 is provided on both sides of the bottom of the U-shaped opening roller groove 101 of each fixed end plate 10 of the welding fixture, and the support bearing 7 extends toward the center direction of the thorn roller 9 to improve the support strength of the thorn roller 9 and facilitate its flipping to weld the thorns 5 in other directions.

[0044] from Figure 5 and Figure 6 It can be seen that each of the fixed end plates 10 of the welding fixture is provided with a limiting plate 11 on the outer side near the triangular protrusions 102 and 103, respectively, for preventing the L-shaped left size mold 2 and the L-shaped right size mold 3 overlapped on the top thereof from scratching the fixed end plate 10 and the slender welding base 1, thereby improving the welding stability of the entire thorn roller 9. The connection method of the limiting plate 11 and its corresponding fixed end plate 10 can be a non-detachable connection after fixing or a detachable fixed connection, and the detachable fixed connection has a more flexible usage method.

[0045] Combination Figure 2 , Figure 5 and Figure 7It can be seen that each of the fixed end plates 10 of the welding fixture has at least one set of circumferential limiting components consisting of a retractable positioning pin 6 and a retractable locking screw 8 in the axial direction toward the thorn roller 9. When the thorns are welded on one side of the thorn roller 9, it is only necessary to flip the thorn roller 9 and overlap the welded thorns 5 between the positioning pin 6 and the locking screw 8 of the circumferential limiting component to provide support for the thorns 5 welded on the outside of the thorn roller 9, thereby limiting the top position of the thorn roller 9 from flipping and always keeping its top position stationary, so that the thorns 5 fixed in the left limiting groove 11 and the right limiting groove 311 of the left support block 21 and several right support blocks 31 can be welded to the relative position of the thorn roller 9, so that all the circumferential thorns 5 can be welded on the same fixture, and only the thorn roller 9 needs to be rotated without moving the entire fixture up and down, thereby improving its fixture efficiency.

[0046] from Figure 1 , Figure 3 as well as Figure 5 It can be seen that the specific working process of the cotton gin working box is as follows:

[0047] Place the thorn roller 9 between the two fixed end plates 10 of the elongated welding base 1, and the distances between the two ends of the thorn roller 9 and the fixed end plates 10 are equal. Place the thorns 5 on the left supporting block 21 and the right supporting block 31 of the L-shaped left size mold 2 and the L-shaped right size mold 3 in turn, use the pressing plate device 4 to stick to the arc surface of the thorns 5 on both sides, and then spot weld 2-3 points at the contact between the thorns 5 and the thorn roller 9, then remove the L-shaped left size mold 2 and the L-shaped right size mold 3, rotate the thorn roller 9, make the thorns 5 at the shaft end of the thorn roller 9 lean against the retractable positioning pin 6, tighten the retractable set screw 8 to just stick to the thorns 5, cover the L-shaped left size mold 2 and the L-shaped right size mold 3, repeat the above steps 4 times in turn, just complete the uniform distribution of the 4 thorns 5 on the circumferential direction of the thorn roller 9, and finally remove the thorn roller 9 and fully weld each thorn 5.

[0048] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
