Description

Technical Field

[0001] The utility model relates to the field of saddle processing, in particular to a jig and a saddle processing system. Background Art

[0002] In order to complete the turnover and storage of aluminum coils and save production sites, a three-dimensional storage method of an elevated warehouse is generally adopted, equipped with an intelligent stacker to pick and store aluminum coils, as Figure 1 shown; the weight of the aluminum coil 1 is gradually transmitted to the cross beam 3 and the column 4 through the saddle 2. When the error of the joint surface with the aluminum coil 1 is large, the saddle 2 is unevenly stressed and easily deformed, and the surface damage of the aluminum coil 1 is also increased, resulting in an increase in waste when the aluminum coil 1 is unrolled for use. Therefore, the manufacturing and assembly accuracy of the saddle 2 is also particularly important. At present, the dimensional accuracy of the directly manufactured saddle 2 is difficult to control, with large errors, and it wastes labor, bringing inconvenience to the construction of workers.

[0003] In related technologies, as Figure 2 and Figure 3 shown, the saddle 2 includes a box-shaped part 21, a support part 23, a special-shaped H-shaped part 22, a rib plate 24 and a bottom plate 25. Each component of the saddle 2 is processed separately and then fixed by welding; in related technologies, a jig is generally used to support the saddle 2. For example, in the patent application with the application number 201310238382.7, the two sides of the jig are H-shaped steel, and a T-shaped plate is used in the middle, and pair welding is carried out by simulating the working state; the jig is a jig made according to the working state, and has the following problems: 1) Since the weight of the aluminum coil 1 is heavy, the structural strength requirements of the saddle 2 result in the heavy weight of each component of the saddle 2. It is difficult for manual handling and adjustment to the jig. The T-shaped jig blocks the upper structure of the saddle 2, making it inconvenient for the overhead crane to lift each component of the saddle 2. The upper part of the saddle 2 needs an external force to move upward to fit the T-shaped jig, and its own weight is not conducive to fitting the jig, and the adjustment is troublesome; 2) After spot welding is completed, the saddle 2 needs to be lifted out of the jig from left to right, and it is inconvenient to take it out of the jig; 3) The jig is not provided with a clamping device, and it depends on manual pressing to fit the jig, with poor stability; the saddle 2 cannot complete all welds on the jig, and many welds cannot be welded flat. Therefore, after spot welding, it is separated from the jig for welding, and the deformation risk is large, and the deformation amount is uncontrollable. It is necessary to re-enter the jig to check whether it is qualified, or other detection means to know whether it is qualified, with low efficiency; 4) It needs to be made in pairs, marked, and paired for assembly, affecting production efficiency.

[0037] The jig 5 includes:

[0038] Base 51, on the upper part of the base 51, there are successively arranged an arc-shaped positioning part 517, an inclined support part 518 and a positioning plate 58 from front to back; the base 51 plays a main supporting role, and each component of the saddle 2 can be placed on the base 51; the arc-shaped positioning part 517 is adapted to the arc-shaped surface of the box-shaped part 21 to place the box-shaped part 21. One side of the box-shaped part 21 facing away from the special-shaped H-shaped part 22 is an arc-shaped surface, which is the side for supporting the aluminum coil 1. The arc-shaped surface of the box-shaped part 21 faces the arc-shaped positioning part 517 and, under the action of gravity, fits on the arc-shaped positioning part 517; the inclined support part 518 is adapted to the special-shaped H-shaped part 22 to place the special-shaped H-shaped part 22. The inclined support part 518 and the structure of the special-shaped H-shaped part 22 cooperate, and the special-shaped H-shaped part 22, under the action of gravity, fits on the inclined support part 518; the positioning plate 58 is adapted to the bottom plate 25 to fix the bottom plate 25.

[0041] Positioner 55, used to install the base 51 and drive the base 51 to rotate horizontally to drive the saddle 2 to rotate; specifically, the positioner 55 includes a support base and a driving component. The driving component is installed on the support base. The driving component can be a motor. The base 51 is installed on the output shaft of the driving component. By the rotation of the driving component, the base 51 is driven to rotate, thereby driving each component of the saddle 2 to rotate. When the corresponding weld seam is in a horizontal state, welding is carried out, and the welding quality is better.

[0042] The jig 5 provided by the present utility model is provided with a base 51, and an arc-shaped positioning portion 517, an inclined support portion 518 and a positioning plate 58 are sequentially arranged on the base 51 from front to back to limit the box-shaped part 21, the special-shaped H-shaped part 22 and the bottom plate 25. The box-shaped part 21 and the special-shaped H-shaped part 22 are directly placed on the base 51, and enter their respective positioning positions by means of the gravity of the box-shaped part 21 and the special-shaped H-shaped part 22 themselves, so that the box-shaped part 21 and the special-shaped H-shaped part 22 can be quickly attached to the base 51. At the same time, by arranging the positioning block 57, the support member 23 can be positioned. And by arranging the fixture, the accurately positioned special-shaped H-shaped part 22 and the support plate can be fastened, so as to ensure the position accuracy of the special-shaped H-shaped part 22 and the support plate during the welding process. The rib plate 24 can be directly placed on the support member 23 and is attached to the bottom plate 25 and the special-shaped H-shaped steel part. That is, the rib plate 24 is also positioned by gravity and is limited by the special-shaped H-shaped part 22 and the bottom plate 25. After all the components on the saddle 2 are placed on the base 51, the positions of the components are determined by spot welding, and then by arranging the positioner 55, the base 51 is driven to rotate by the positioner 55, so that the welds between the components can be in a horizontal state, which is convenient for welding and improves the welding quality. By accurately positioning and improving the welding quality, a single saddle 2 can be welded without paired assembly, which can simplify the assembly process of the saddle 2, is convenient for operation, and improves the accuracy and efficiency.

[0043] In some embodiments, the fixture includes a horizontal fixture 53 and a vertical fixture 54. The horizontal fixture 53 can abut against the middle plate of the special-shaped H-shaped part 22, and the vertical fixture 54 can abut against the side plate of the special-shaped H-shaped part 22 or the bottom surface of the support member 23. The middle plate of the special-shaped H-shaped part 22 refers to the plate located in the middle of the special-shaped H-shaped part 22, and the side plates of the special-shaped H-shaped part 22 refer to the plates located on both sides of the middle plate. The side plates of the special-shaped H-shaped part 22 are placed on the base 51, and the middle plate of the special-shaped H-shaped part 22 is perpendicular to the side plates of the special-shaped H-shaped part 22. By fixing with the middle plate and side plates of the special-shaped H-shaped part 22, the positioning of the special-shaped H-shaped part 22 in the vertical and horizontal directions can be realized. Further, the numbers of the horizontal fixture 53 and the vertical fixture 54 are both multiple, and the vertical fixture 54 can also press the support member 23 in the vertical direction. The support member 23 is a channel steel, the opening of the support member 23 faces the positioning block 57 and is placed on the positioning block 57, and the bottom surface of the support member 23 is a plane, which is convenient for the vertical fixture 54 to press and position.

[0045] In some embodiments, both the horizontal fixture 53 and the vertical fixture 54 are push-pull type quick clamps. The end of the movable part of the push-pull type quick clamp is provided with a contact head, which can be cylindrical or frustum-shaped, to increase the contact area and reduce the damage of the push-pull type quick clamp to the saddle 2.

[0046] In some embodiments, the positioning block 57 includes a first side block 571, a second side block 572, and a fixing plate 573. The fixing plate 573 is located between the first side block 571 and the second side block 572, and grooves are provided on both the first side block 571 and the second side block 572.

Through holes are provided at positions on the positioning plate 58 corresponding to the bolt holes of the bottom plate 25, and the precision reamed bolt 56 passes through the bolt holes and the through holes. The precision reamed bolt 56 is used to position the bolt holes and the through holes. Since the outer diameter of the precision reamed bolt 56 is larger than that of an ordinary bolt, therefore, by using a precision reamed bolt 56 that matches the sizes of the bolt holes and the through holes, the positioning accuracy of the bolt holes and the through holes can be ensured, thereby ensuring the welding accuracy of the bottom plate 25 and the special-shaped H-shaped member 22, and ensuring the subsequent assembly of the bottom plate 25 with ordinary bolts.

[0048] In some embodiments, the base 51 includes a left plate 511, a right plate 512, a front connecting member 513, and a rear connecting member 514. The left plate 511 and the right plate 512 are symmetrically and parallelly arranged and have the same structure. The front connecting member 513 is connected to the front ends of the left plate 511 and the right plate 512 for fixing the front ends of the left plate 511 and the right plate 512. The rear connecting member 514 is connected to the rear ends of the left plate 511 and the right plate 512 for fixing the rear ends of the left plate 511 and the right plate 512. The rear connecting member 514 is installed on the positioner 55.

A card slot 519 is provided between the arc-shaped positioning portion 517 and the inclined support portion 518 to limit the relative positions of the box-shaped member 21 and the special-shaped H-shaped member 22. Through the setting of the card slot 519, it can be ensured that after the box-shaped member 21 is placed on the base 51, it can remain in a specific position under the action of its own gravity and avoid displacement. The special-shaped H-shaped member 22 is then determined in its position under the restriction of the box-shaped member 21.

[0049] In some embodiments, the base 51 further includes a bottom connecting member 515 and an intermediate support plate 516. The intermediate support plate 516 is perpendicular to the left plate 511 and the right plate 512, and the intermediate support plate 516 effectively supports the positioning block 57. Moreover, the horizontal clamp 53 and the vertical clamp 54 for fixing the support member 23 are both installed on the intermediate support plate 516.

[0051] In some embodiments, the left plate 511 and the right plate 512 are further provided with avoidance grooves, and the avoidance grooves are located on both sides of the inclined support portion 518. The avoidance grooves can be arc-shaped grooves. The arrangement of the avoidance grooves can facilitate the welding of the welds on the side close to the base 51 between the box-shaped member 21 and the special-shaped H-shaped member 22, and the welding of the welds on the side close to the base 51 between the bottom plate 25 and the special-shaped H-shaped member 22. At the same time, the arrangement of the avoidance grooves serves as a lifting hole. After the saddle 2 is welded, the saddle 2 can also be lifted by threading a rope into the avoidance grooves, which is convenient for disassembly.

[0052] Specifically, in one embodiment, the jig 5 includes a base 51. At the position on the positioning plate 58 of the base 51 where through holes are pre - machined, the through holes correspond to the bolt holes of the bottom plate 25. And at the position on the base 51 where the arc surface of the box - shaped part 21 is pre - machined for positioning, that is, the arc - shaped positioning part 517. Baffles 52 are arranged at multiple parts of the base 51 to position the saddle 2. A horizontal push - pull type quick clamp and a vertical push - pull type quick clamp are provided. A positioner 55 is set to achieve the rotation function. The bottom plate 25 of the saddle 2 is connected with a precision - reamed bolt M12. A positioning block 57 is used to support the channel steel support 23 of the saddle 2. The jig 5 is in the state where the saddle 2 is upward. The bottom plate 25 is assembled onto the positioning plate 58 provided on the jig 5 and connected with a precision - reamed bolt M12. Since the nominal size of the connecting smooth rod part of the precision - reamed bolt 56 is φ13mm and the hole diameter is φ14, after positioning with this bolt, when assembling with an ordinary M12 bolt after the welding of the saddle 2 is completed, it is relatively smooth. After the box - shaped part 21 is automatically in place by its own weight, adjust the symmetry at both ends of the length and clamp it with the vertical clamp 54. After the two - side special - shaped H - steel parts are in place in the horizontal and vertical directions, they are clamped with the horizontal clamp 53 and the vertical clamp 54. Then the support 23 is in place at the position of the positioning block 57, and the vertical clamp 54 clamps the support 23. Finally, the rib plate 24 is attached to the support 23 and is spot - welded after being fitted with the bottom plate 25 and the special - shaped H - steel parts. Then spot - weld each part, and then start welding. The positioner 55 rotates to make the weld seam in a horizontal state for welding. After welding is completed, the positioner 55 rotates to the state where the saddle 2 is upward, loosen each clamp, and check the gap with a feeler gauge. The saddle 2 is lifted out of the jig 5.

[0053] For the jig 5 provided by the present utility model, each component of the saddle 2 can be placed on the jig 5 by a crane, which is convenient for operation. Each component of the saddle 2 enters its respective positioning position under its own weight and can quickly fit with the jig 5. It is more convenient for the saddle 2 to be removed from the jig 5. The base 51 of the jig 5 is rotated by the positioner 55 to make the weld seam as horizontal as possible to ensure the welding quality. Each component is fixed on the jig 5 by a clamp, and all weld seams can be welded on the jig 5. It is only after welding is completed that it is separated from the jig 5, reducing deformation. After loosening the clamp, the fitting situation can be checked to determine whether the saddle 2 is qualified. It can realize the production of a single saddle 2, ensure its accuracy, does not require paired assembly, and has high efficiency.

[0054] The present utility model also provides a saddle 2 processing system including the above - mentioned jig 5. For the structures of other parts of this saddle 2 processing system, please refer to the related technologies and will not be elaborated herein.

[0055] In this specification, each embodiment is described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. For the same or similar parts among the embodiments, reference can be made to each other.
