Description

Technical Field

[0001] This utility model belongs to the field of steel structure manufacturing, specifically relating to a positioning fixture for splicing flanges and webs. Background Technology

[0002] In the field of steel structure manufacturing, flanges and webs are the core components of T-beams, H-beams, I-beams, and other structural members. The quality of their splicing directly affects the load-bearing capacity and structural stability of the members.

[0003] For example, Chinese patent CN208895451U discloses a T-shaped steel processing table, including a template base, a web, a flange, and a clamping set. The template base includes a flat base and an L-shaped steel plate. The L-shaped steel plate is symmetrically and parallelly arranged in an inverted L shape along the vertical direction on the flat base to form a web placement groove corresponding to the outer dimensions of the web. The web is embedded in the web placement groove. The flange has openings for through-hole plug welding. The flange is clamped and fixed to the top of the web by the clamping set.

[0004] Although the device can ensure that the T-shaped steel products meet the process requirements after welding, it requires four sets of G-type clamps to position the web and flange plates during assembly and positioning. Furthermore, if deviations occur during processing, fine adjustments need to be made using positioning adjustment bolts, which is cumbersome and inefficient.

[0005] Therefore, we propose a positioning fixture for splicing the flange and web to solve the above problems. Utility Model Content

[0006] To address the problem that the device requires four sets of G-type clamps to position the web and flange plates during assembly and positioning, and that if deviations occur during processing, fine adjustments must be made using positioning adjustment bolts, which is cumbersome and inefficient, this utility model provides a flange and web plate splicing and positioning fixture.

[0007] The solution adopted by this utility model to solve its technical problem is: a flange plate and web plate splicing and positioning fixture, including a flange plate support unit and two sets of symmetrically arranged web plate clamping mechanisms. The flange plate support unit includes two parallel bases, and multiple support rods are welded and fixed between the two bases.

[0008] The web plate clamping mechanism includes a drive motor, a rotating shaft, a flipping plate, and a clamping plate. Bearing seats are fitted at both ends of the rotating shaft, and the bearing seats are fixedly installed on the base. The output shaft of the drive motor is connected to the rotating shaft to drive the rotating shaft to rotate.

[0009] Multiple connectors are fixedly installed on the rotating shaft. The lower end of the flip plate is fixedly connected to the connectors. The clamping plate is set parallel to the flip plate and is used to clamp the side of the web plate. A telescopic component is fixedly installed between the clamping plate and the flip plate.

[0010] Preferably, two limiting wheels are installed at the top of the support rod, and the flange plate is placed between the two limiting wheels.

[0011] Preferably, the telescopic component is a hydraulic rod or an electric cylinder.

[0012] Preferably, telescopic rods are provided on both sides of the telescopic member, and the telescopic rods are fixedly installed between the clamping plate and the flipping plate.

[0013] Preferably, the connector is a fixing sleeve.

[0014] Preferably, the base and the support rod are both made of rectangular rods.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model places the flange plate on multiple support rods and uses the limiting wheels on both sides to initially position the flange plate. By controlling the synchronous extension of the hydraulic rods on both sides, the two clamping plates are brought closer to each other, and the two sides of the web plate are clamped at the same time, so that the web plate is placed vertically on the flange plate. The flange plate and the web plate are spliced ​​and positioned, which greatly simplifies the positioning operation, reduces the operation steps, and thus significantly improves the assembly efficiency.

[0017] 2. This utility model uses a drive motor to drive the rotating shaft to rotate 90 degrees. The rotating shaft drives the rotating plate and clamping plate to rotate, flipping the rotating plate and clamping plate to the top of the base, so that the lifting equipment can lift the welded flange plate and web plate from the support rod for the next step of processing.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1-2This utility model provides a technical solution for a positioning fixture for splicing the flange plate and the web plate:

[0023] Example 1:

[0024] according to Figure 1 and Figure 2 As shown, it includes a flange support unit and two sets of symmetrically arranged web clamping mechanisms.

[0025] The flange support unit includes two parallel bases 1, and multiple support rods 2 are welded and fixed between the two bases 1. The bases 1 and support rods 2 are made of rectangular rods. The bases 1 and support rods 2 together form a stable support frame. Two limiting wheels 3 are installed on the top of the support rods 2. The flange is placed between the two limiting wheels 3. The flange is initially positioned by the limiting wheels 3 on both sides, which restricts its lateral movement.

[0026] The web plate clamping mechanism includes a drive motor 41, a rotating shaft 43, a flipping plate 51, and a clamping plate 54. Bearing seats 42 are respectively fitted at both ends of the rotating shaft 43. The bearing seats 42 are fixedly installed on the base 1. The rotating shaft 43 is supported by the two bearing seats 42 to ensure the stability of the rotating shaft 43 during rotation. The output shaft of the drive motor 41 is connected to the rotating shaft 43 to drive the rotating shaft 43 to rotate.

[0027] Multiple connectors 44 are fixedly installed on the rotating shaft 43. The connectors 44 are fixed sleeves. The lower end of the flip plate 51 is fixedly connected to the connectors 44, so that the rotating shaft 43 drives the flip plate 51 to rotate synchronously. The clamping plate 54 is arranged parallel to the flip plate 51. A telescopic component is fixedly installed between the clamping plate 54 and the flip plate 51. The telescopic component is a hydraulic rod 52 or an electric cylinder. By controlling the synchronous extension of the hydraulic rods 52 on both sides, the two clamping plates 54 are brought closer to each other, and the two sides of the web are clamped at the same time, so that the web is placed vertically on the flange plate, and the flange plate and the web plate are spliced ​​and positioned.

[0028] Telescopic rods 53 are provided on both sides of the hydraulic rod 52. The telescopic rods 53 are fixedly installed between the clamping plate 54 and the tilting plate 51. The telescopic rod 53 consists of a sleeve and an extension rod set inside the sleeve. The extension rod can slide along the inner cavity of the sleeve. The clamping plate 54 and the tilting plate 51 are connected by the telescopic rods 53, which improves the stability of the clamping plate 54 during movement and protects the hydraulic rod 52.

[0029] In practical use, the flange plate and web plate splicing positioning fixture of this utility model first places the flange plate on multiple support rods 2 and between the two limit wheels 3 to perform preliminary positioning of the flange plate. Then, the web plate is placed vertically on the flange plate, and it is ensured that the edge of the web plate is aligned with the edge of the flange plate. Then, the two drive motors 41 are started. The drive motors 41 drive the rotating shaft 43 to rotate 90 degrees. The rotating shaft 43 drives the rotation of the flipping plate 51 and the clamping plate 54, so that the clamping plates 54 on both sides are parallel to the web plate.

[0030] The synchronous extension of the hydraulic rods 52 on both sides is controlled to bring the two clamping plates 54 closer to each other and clamp the two sides of the web plate so that the web plate is placed vertically on the flange plate. The flange plate and the web plate are spliced ​​and positioned. Then the workers perform the splicing process on the flange plate and the web plate to firmly connect the flange plate and the web plate together.

[0031] After the splicing is completed, the hydraulic rods 52 on both sides are controlled to retract synchronously, so that the clamping plate 54 is away from the web plate. Finally, the two drive motors 41 are started again. The drive motors 41 drive the rotating shaft 43 to rotate 90 degrees. The rotating shaft 43 drives the rotating plate 51 and the clamping plate 54 to rotate, so that the rotating plate 51 and the clamping plate 54 are flipped to the top of the base 1, so that the lifting equipment can lift the welded flange plate and web plate from the support rod 2 for the next step of processing.
