Description

Technical Field

[0001] This utility model belongs to the field of idler bracket welding and processing technology, and in particular relates to an automatic welding and fixing frame for idler brackets. Background Technology

[0002] In the field of material idler technology, a material idler consists of several idler supports, idlers, and a conveyor belt on the idlers. This type of material idler is usually equipped with two rows of idlers, which are symmetrically inclined and surround the conveyor belt to form a V-shaped ring structure, thereby achieving stable material conveying.

[0003] This utility model relates to the welding technology of a single idler roller bracket. As a general structure, this type of idler roller bracket includes a bracket base, with two fixing plates at the bottom of the bracket base. Two outer frames and two inner frames are symmetrically welded to the upper part of the bracket base. The top of the outer frames is inclined towards the inner frames, and the height of the inner frames is lower than that of the outer frames, thereby achieving inclined support for the idler roller.

[0004] In existing technologies, this type of idler support is mainly welded manually. Typically, a fixing plate and an angle iron support base are placed sequentially on a platform, followed by the fixing and welding of the outer and inner frames. However, manual welding has several drawbacks, summarized as follows: 1. Low efficiency: Operators must manually guide each component during welding, resulting in slow speed; 2. Poor welding precision: Manual welding can easily cause material displacement, making stable fixing impossible and compromising welding precision; 3. Because the idler support has two symmetrical sets of inner and outer frames, to ensure conveying stability, the two sets of inner and outer frames must be symmetrical on the support base. However, manual welding cannot guarantee perfect symmetry between the two sets of inner and outer frames, leading to potential misalignment or even detachment of the conveyor belt when it rotates above it after welding.

[0005] In view of the above technical problems, it is necessary for those skilled in the art to improve the existing welding methods by using automatic or semi-automatic welding equipment to weld the above components. However, the above welding equipment must be equipped with a dedicated welding fixture to ensure the accuracy and stability of the welding process. Summary of the Invention

[0006] In view of the shortcomings of the prior art described above, this utility model proposes an automatic welding and fixing frame for idler roller brackets. By setting support devices or clamping devices on the left and right sides and in the middle, the components are precisely positioned during welding to avoid displacement of the components during the welding process. Furthermore, the clamping device in the middle achieves symmetrical compression from left to right to avoid asymmetry.

[0014] The side adjustment plate is located below the middle rod, and the side adjustment plate is provided with an inner frame positioning rod.

[0015] The two fixed piles include a positioning pile and a movable pile; the positioning pile is surrounded by a positioning column, which is used to position the fixed plate.

[0016] The top surface of the fixing base is also provided with a central adjustment groove, and a transverse baffle is provided in conjunction with the central adjustment groove to achieve lateral positioning of the fixing plate. The side of the fixing base is also provided with a side adjustment groove to achieve lateral adjustment of the longitudinal baffle, which is oriented towards the fixing plate.

[0017] The fixed base has several positioning blocks arranged front and back, and a bracket positioning rod is provided through the positioning block. The bracket positioning rod is used to achieve the longitudinal positioning of the bracket on the fixed base.

[0028] The automatic welding and fixing frame structure of the idler roller bracket disclosed in this utility model is quite novel. The beneficial effects of its overall structural improvement are obvious. In order to make the improved effects of this utility model clearer, the following describes this utility model in further detail through specific embodiments.

[0029] Example 1:

[0030] An automatic welding and fixing frame for idler roller supports is used to achieve, for example... Figure 5 , 6 The illustrated idler bracket includes a bracket base 7 with an angle iron structure, two fixing plates 71 welded to the bottom of the bracket base 7, two outer frames 72, and two inner frames 73. The fixing plates 71 have holes or slots for assembling the idler bracket with external components. The tops of the outer frames 72 are bent towards the inner frames 73.

[0031] like Figure 1 , 2 As shown in Figures 3 and 4, this utility model includes a fixed base 1, and four locking plates 10 are provided on the four corners of the bottom of the fixed base 1 as fixing points for fixing to the external platform.

[0032] Fixed piles are provided on both the left and right sides of the fixed base 1. Since this utility model needs to be welded to roller brackets of different models, it must correspond to bracket bases 7 of different lengths. Therefore, the two fixed piles of this utility model include positioning piles 2 and movable piles 6. A movable pile adjustment groove 13 is provided on the top surface of the fixed base 1. A base plate is provided at the bottom of the movable pile 6 to cooperate with the movable pile adjustment groove 13 to achieve lateral adjustment and locking fixation, thereby adjusting the relative distance between the positioning pile 2 and the movable pile 6, and thus achieving positioning of bracket bases 7 of different lengths.

[0033] The positioning pile 2 is provided with positioning posts 19 around it. The positioning posts 19 are inserted into the fixing plate 71 to position the fixing plate 71 on one side.

[0034] This utility model provides inner and outer blocking components on the positioning pile 2 and the movable pile 6, respectively. It should be noted that the inner and outer blocking components are not fixed to the positioning pile 2 or the movable pile 6 in this technical solution. The inner blocking component can be provided on the positioning pile 2 and the outer blocking component can be provided on the movable pile 6; or the outer blocking component can be provided on the positioning pile 2 and the inner blocking component can be provided on the movable pile 6. However, it must be ensured that the inner and outer blocking components are present in the automatic welding fixing frame of this roller bracket at the same time.

[0035] In this embodiment, the positioning stake 2 is provided with an inner blocking member, and the movable stake 6 is provided with an outer blocking member. The inner blocking member includes an inner bottom bracket 21 with a right-angle structure, a middle bracket I 22, and an inner top bracket 23, as shown below. Figure 1 , 2 As shown, the inner bottom bracket 21 is equipped with an inner adjusting screw 211, and the middle bracket I 22 is equipped with a side adjusting screw I 221; the inner top bracket 23 is equipped with an inner inclined plate 231, which is used to fix the inner top adjusting screw 232. With this structural arrangement, the outer frame 72 can be simultaneously fixed at three locations: the inner bottom bracket 21, the middle bracket I 22, and the inner top bracket 23. Because the outer frame 72 has a bottom cross-section larger than its top cross-section, and the top of the outer frame 72 bends towards the inner frame 73, the outer frame 72 can be stably fixed when fixed only by the inner blocking member.

[0036] In this embodiment, the movable pile 6 is provided with an outer blocking component, which includes an outer bottom bracket 61, a middle bracket II 62, and an outer top bracket 63. The outer bottom bracket 61 is provided with an outer adjusting screw 611, and the middle bracket II 62 is provided with a side adjusting screw II 621. The outer top bracket 63 is provided with an outer inclined plate 631, and the outer inclined plate 631 is provided with an outer top adjusting screw 633. The outer top adjusting screw 633 is also provided with an outer top adjusting disc 632 for adjusting the outer top adjusting screw 633. Through the above structural configuration, the outer side of the outer frame 72 can be adjusted. The outer frame 72 is compressed and fixed. However, after the above structure is set, the outer frame 72 itself has a tendency to tilt inward. In order to ensure the stability of the outer frame 72, this utility model also has an inner compression member in cooperation with the outer blocking member. In this embodiment, the inner compression member is a quick clamp 64. The quick clamp 64 is fixed on the quick clamp seat 65, and the quick clamp seat 65 is fixed on the movable pile 6. After the above structure is set, when the outer frame 72 is placed vertically on the support base 7, it is compressed and fixed at three points on the outside by the outer bottom bracket 61, the middle bracket II 62 and the outer top bracket 63, and flexibly clamped on the inside by the quick clamp 64.

[0037] The purpose of this utility model is to use the inner and outer blocking components together so that, after the roller bracket is welded, if all the above-mentioned blocking components are inner or outer blocking components, the roller bracket welded together cannot be removed from the mold. Therefore, when the above design uses an inner blocking component on one side and an outer blocking component on the other side, the roller bracket can be vertically lifted after welding, and then a force is applied to one side to horizontally push the roller bracket to remove it from the mold.

[0038] This utility model provides a horizontal adjustment seat 3 in the middle region of the fixed base 1. A T-slot 31 is provided inside the horizontal adjustment seat 3 as a guide. A central column 4 is provided in conjunction with the T-slot 31. A T-shaped block 40 on the central column 4 cooperates with the T-slot 31 to achieve horizontal guidance. A vertical groove 41 is provided vertically on the upper part of the central column 4. A vertical adjustment rod 42 is vertically fixed inside the vertical groove 41, allowing for vertical movement and adjustment within the vertical groove 41. A U-shaped block is provided at the front end of the vertical adjustment rod 42. 43. A U-shaped groove 431 is provided inside the U-shaped block 43. A locking pressure plate 46 is provided inside the U-shaped groove 431 for pressing the middle rod 8. A positioning groove 81 is provided on the middle rod 8 to assemble with the U-shaped block 43. After assembly, the middle rod 8 can be prevented from swinging. Side adjustment plates 83 and top pressing rods 82 are provided at both ends of the middle rod 8. The side adjustment plates 83 are located below the middle rod 8 and an inner frame positioning rod 84 is provided through the side adjustment plates 83. The position of the inner frame 73 can be fixed by the inner frame positioning rod 84.

[0039] After setting the above structure, as follows: Figure 5 , 6 As shown, the horizontal adjustment seat 3 can adjust the entire central column 4 left and right. This adjustment is used for center alignment when welding brackets 7 of different lengths. During batch product welding, the relative adjustment between the horizontal adjustment seat 3 and the central column 4 is not frequent, and it is not changed arbitrarily after a single adjustment.

[0040] This invention fixes a locking plate 46 to a pressing screw 44, the pressing screw 44 having a force-applying handle 45 at its top. During welding, the locking plate 46 presses against the middle rod 8 by quickly tightening the force-applying handle 45, thereby pressing down the top pressing rod 82 to position the inner frame 73. This structure enables rapid locking and disassembly of the entire middle rod 8, allowing for the removal and placement of the welded roller bracket after disassembly.

[0041] like Figure 1 , 4 As shown, the present invention also provides two central adjustment grooves 12 on the top surface of the fixing base 1, and a transverse baffle 3 is provided in conjunction with the two central adjustment grooves 12 to achieve side positioning of the fixing plate 71. The side of the fixing base 1 is also provided with a side adjustment groove 11 to fix the baffle fixing part 14. The baffle fixing part 14 is also provided with a longitudinal baffle 15, which faces the fixing plate 71. The above structure is used in conjunction with the positioning column 19. When fixing the bracket 7, the positioning column 19 is used to fix one side of the fixing plate 71 first, and then the longitudinal baffle 15 and the transverse baffle 3 are used to fix the other side of the fixing plate 71. Since the roller bracket can be lifted vertically by slightly moving it to the left or right after welding, this horizontal and vertical movement must be constrained by the positioning column 19 as little as possible. Therefore, this utility model only sets the positioning column 19 on the fixing plate 71 on one side of the bracket 7, and does not use the positioning column 19 when fixing the fixing plate 71 on the other side. Only horizontal constraint is applied on the horizontal plane. This structure makes it easier to remove the roller bracket after welding.

[0042] This utility model also has several positioning blocks 17 arranged in front and behind the fixed base 1. A bracket positioning rod 18 is provided through the threaded hole on the positioning block 17. The longitudinal positioning of the bracket 7 on the fixed base 1 is achieved by adjusting the bracket positioning rod 18. This design can ensure that the bracket 7 is stable and does not move during welding, and improve the matching accuracy between the components before and during welding.

[0043] In summary, this utility model improves welding efficiency, eliminating the need for operators to manually guide each component during welding; it also achieves high welding precision, as the positioning structure enables the positioning of each component during the welding process, thus enhancing welding accuracy; and by designing the central column 4 and central rod 8 for assembly and positioning, it improves the symmetry of the left and right inner and outer frames on the support base, completely overcoming the problem of the conveyor belt easily shifting or even detaching after welding.

[0044] This invention can be used for manual welding, and can also be connected with automatic or semi-automatic equipment to achieve automatic welding. It can not only ensure accuracy, but also improve welding efficiency. It is an ideal automatic welding fixing frame for idler roller brackets.
