Description

Technical Field

[0001] The utility model belongs to the technical field of manufacturing equipment for bent and twisted boxes, and particularly relates to a jig device for manufacturing large-span bent and twisted boxes. Background Art

[0002] With the rapid development of construction projects, many new building shapes have emerged, such as bent and twisted boxes. A bent and twisted box is formed by bending a rectangular box along the horizontal or vertical direction and twisting along the axis of the box. In the prior art, the assembly and welding of the box are generally carried out on a jig. However, since the shapes of the box plates forming the bent and twisted box are irregular, and the jig itself is composed of steel and cannot change its shape according to the bent and twisted box, when the box is assembled on the jig, the gap between the bent and twisted box and the jig is large. When assembling and welding the web or top plate of the box, the box located on the jig vibrates, resulting in unstable assembly and welding and affecting the manufacture of the box.

[0003] The document with the authorization announcement number CN220697926U discloses a manufacturing device for bent and twisted boxes, including a plurality of jigs on which the bent and twisted boxes are placed. The jig includes a cross beam and support columns perpendicular to both ends of the cross beam. The cross beam includes, from top to bottom, a movable plate layer that deforms under force, a buffer layer, a leaf spring, and a filling layer. The movable plate layer includes a plurality of movable plates. First through holes are formed through both sides of the movable plate, and first pin shafts are inserted into the first through holes. The movable plates can rotate around the first pin shafts. The movable plate layer further includes two parallel binding ropes. Both sides of the binding ropes are fixedly connected to the cross beam, and a plurality of round holes are spaced on the binding ropes. Both ends of the first pin shaft respectively pass through the round holes on the two parallel binding ropes.

[0004] The working principle of this device is as follows: The movable plate layer formed by hinging a plurality of movable plates makes the shape of the movable plate layer close to the shape of the bent and twisted box itself, thereby reducing vibration during production.

[0005] However, this device still has the following problems: First, the number of movable plate layers directly determines the fitting effect of the device, and increasing the number of movable plate layers has a high economic cost. Second, the structures connecting the movable plate layers are pin shafts and binding ropes, and the connection strength is low, and the stability of the device is poor. Summary of the Utility Model

[0006] Aiming at the above problems, the purpose of the utility model is to provide a jig device for manufacturing large-span bent and twisted boxes.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection: it can be a mechanical connection or an electrical connection: it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0037] As shown in the attached Figure 1 drawing, the bent and twisted box body used for processing in this application is a kind of prior art, including a lower wing plate, an upper wing plate and two web plates. The formed bent and twisted box body is placed on a jig.

[0038] As shown in the attached Figure 2 drawing, the jig for manufacturing the bent and twisted box body is composed of a cross beam 11 and a support column 12 connected. An active plate layer is arranged at the uppermost end of the cross beam, and a buffer layer, a leaf spring and a filling layer can be sequentially arranged at the lower end of the active plate layer. The active plate layer is composed of a plurality of active plates connected in sequence. According to the principle of differentiation, the more the number of active plates connected, the more closely the shape of the active plate layer fits the bent and twisted box body. On this basis, the structure of the active plate layer is reformed in this embodiment to reduce the total amount of active plates and still maintain the fit with the bent and twisted box body.

[0039] Embodiment 1

[0040] In this embodiment, as shown in the attached Figure 3 drawing and the attached Figure 4 drawing, the active plate layer includes a plurality of active plates 21, a connector 22 for connecting two adjacent active plates 21, and a support member 23 arranged between two opposite connectors 22; among them,

[0041] A connecting rod 211 is disposed through the end of the movable plate 21, and a first external thread section is provided on the connecting rod 211;

[0042] The number of the connectors 22 is two, which are oppositely disposed on both sides of the connection of two adjacent movable plates 21, that is, the ends of the two movable plates 21 on the same side are connected by one connector 22; each connector 22 includes a connecting plate 221, two first mounting holes 222 provided at both ends of the connecting plate 221 and adapted to the connecting rod 211, and a first fixing nut 223 screwed on the connecting rod 211 for fixing the connecting plate 221;

[0043] The support member 23 includes a support rod 231 whose two ends are respectively detachably connected to the two connecting plates 221.

[0044] In this embodiment, a preferred structure for the detachable connection between the support rod 231 and the connecting plate 221 is: the connector 22 further includes a second mounting hole 224 provided on the connecting plate 221 and adapted to the support rod 231; the support member 23 further includes a second external thread section provided at the end of the support rod 231, and two second fixing nuts 232 screwed on the support rod 231 and located on both sides of the connecting plate 221.

[0045] It should be noted that in the structure of using two connectors 22 to connect two adjacent movable plates 21, the distance between the two movable plates 21 is relatively small, generally 1 / 10 to 1 / 8 of the length of the movable plate 21. The two movable plates 21 can rotate relative to each other under the connection of the connectors 22 to adapt to the shape of the bent and twisted box body, and the support rod 231 installed in the gap can fill the gap and play a role in supporting the bent and twisted box body. The installation position of the support rod 231 needs to ensure that the surface height is not higher than the highest position of the movable plate 21, so as to prevent the support rod 231 from lifting the bent and twisted box body alone.

[0046] Embodiment 2

[0047] As shown in the appendix Figure 5 This embodiment is different from Embodiment 1 in that the length of the connecting plate 221 is extended, and the distance between the two movable plates 21 is 1 / 8 to 1 / 5 of the length of the movable plate 21. At this time, the number of the second mounting holes 224 on a single connecting plate 221 increases, preferably 3, which ensures that at most 3 support rods 231 can be installed between the two opposite connectors 22, so as to ensure the support strength of the bent and twisted box body at the gap.

[0048] As a preference of this embodiment, the second mounting hole 224 includes a hole body 224a, a fixing ring 224b concentrically arranged in the hole body 224a, and a support spring 224c arranged on the inner wall of the hole body 224a and connected to the fixing ring 224b. The purpose of such a setting is to enable the support rod 231 to have the ability to displace within the second mounting hole 224 under a stressed state, so that the support rod 231 can move within a certain range as a whole, thereby ensuring that all the support rods 231 can fit the surface of the bent and twisted box body, reducing the gap between the bent and twisted box body and the movable plate layer, and reducing the generation of vibration.

[0049] Embodiment 3

[0050] The difference between this embodiment and Embodiment 1 is that the length of the connecting plate 221 is adjustable, so as to adjust the distance between the two movable plates 21, and further reduce the number of the movable plates 21. As shown in the attached Figure 6 figure, the specific structure is as follows:

[0051] The second mounting hole 224 includes a hole body 224a, a fixing ring 224b concentrically arranged in the hole body 224a, and a support spring 224c arranged on the inner wall of the hole body 224a and connected to the fixing ring 224b.

[0052] The connecting plate 221 includes a first plate body 221a, two second plate bodies 221b arranged at both ends of the first plate body 221a, and an adjusting member for adjusting the distance between the second plate body 221b and the first plate body 221a; at least one of the second mounting holes 224 is arranged on the first plate body 221a, and the first mounting hole 222 is arranged at the end of the second plate body 221b and at least one of the second mounting holes 224 is arranged.

[0053] The adjusting member includes a threaded groove 221c1 arranged at the end of the first plate body 221a, a fixing groove 221c2 arranged at the end of the second plate body 221b, an adjusting rod 221c3 with one end screwed to the threaded groove 221c1 and the other end rotatably connected to the fixing groove 221c2, an annular groove 221c4 arranged on the groove side wall of the fixing groove 221c2, and a limiting block 221c5 arranged on the adjusting rod 221c3 and slidably connected to the annular groove 221c4.

[0054] The working principle of the adjusting member is: rotating the adjusting rod 221c3, one end of the adjusting rod 221c3 rotates due to the limiting block 221c5 being fixed in the annular groove 221c4, and the other end of the adjusting rod 221c3 can be screwed into / out of the threaded groove 221c1 due to being screwed to the threaded groove 221c1, thereby adjusting the distance between the second plate body 221b and the first plate body 221a.

[0055] Example 4

[0056] The difference between this embodiment and Embodiment 1 is that the connecting plate 221 is not extended, but the number of connectors 22 on the same side of the two movable plates 21 is increased. The distance between the two movable plates 21 is 1 / 5 to 1 / 2 of the length of the movable plate 21. At this time, the number of connectors 22 on the same side can be 3 or more than 3, and the number of connectors 22 on the opposite side also increases accordingly. Adjacent two of the connectors 22 are connected by bolts adapted to the first mounting holes 222. As shown in the appendix Figure 7 shown, the specific examples are as follows:

[0057] Taking the connection with 3 connectors 22 arranged on the same side as an example, the positions of the two connectors 22 respectively connected to the two movable plates 22 are the same, and both ends of the third connector 22 are connected to the ends of the previous two connectors 22 by bolts. The connectors can rotate relative to the movable plates and relative to each other, ensuring to fit the bottom surface of the bent and twisted box body, and a support rod 231 for improving the support effect is still arranged between the two opposite connectors.

[0058] Example 5

[0059] This embodiment optimizes the structure on the basis of Embodiment 4, aiming to supplement the support strength of the gap between the two support rods 231. As shown in the appendix Figure 7 and the appendix Figure 8 shown, the specific structure is as follows:

[0060] The support member 23 further includes a flat plate 233 detachably installed on the side end of the support rod 231 and arranged along the length direction of the support rod 231, and a plurality of rod bodies 234 vertically arranged on the flat plate 233. The rod bodies 234 on adjacent two support rods 231 are staggered.

[0061] As a further preference of the embodiment, a plurality of spaced mounting grooves 231a are arranged on the support rod 231, and at least one insertion post 233a connected to the mounting groove 231a is arranged on the flat plate 233.

[0062] In this embodiment, the staggered rod bodies 234 fill the gap between the support rods 231, and the formed cross-tooth structure has the advantage of good support effect. It should be noted that the height of the rod body 234 is not higher than the highest position of the support rod 231, which can be achieved by rotatably connecting the support rod 231 to the connecting plate 221.

[0063] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the art to which the present utility model pertains may make various modifications or supplements to the described specific embodiments or use similar means for substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
