Description

Technical Field

[0001] The invention relates to the technical field of clamp assembly, in particular to an automatic assembly machine for fire-fighting clamps. Background Art

[0002] The clamp is a connection device for connecting grooved pipes, valves and pipeline accessories. It is used to tighten the connection between quick connectors. Generally, the connector is equipped with gaskets, rubber, silicone and PTFE. It has good performance, high sealing and easy installation. According to the material, the clamp can be divided into stainless steel double wire clamp, carbon steel double wire clamp, phosphor bronze double wire clamp, galvanized double wire clamp and nickel-plated double wire clamp. Cast iron clamp is directly cast. It is mostly used for building pipeline installation. It has good performance, high sealing and easy installation.

[0003] Firefighting pipes refer to pipe materials used in firefighting to connect firefighting equipment and devices and to transport firefighting water, gas or other media. Due to special needs, there are special requirements for the thickness and material of firefighting pipes, and they are sprayed with red paint to transport firefighting water. Since firefighting pipes are often in a static state, the requirements for pipes are relatively strict. Pipes need to be resistant to pressure, corrosion and high temperature. The installation of firefighting pipes stipulates that flexible joints should be used in places with vibration and buried pipes, and rigid joints should be used in other places. When rigid joints are used, a flexible joint should be set every 4 to 5 rigid joints.

[0004] The clamp is a very common fire pipe connector. The clamp is generally composed of two semicircular pipe sleeves. The inner part of the pipe sleeve is provided with a sealing gasket that is sleeved on the pipe, and the outer part is fixed together with screws. In order to use it more conveniently, the clamp is generally delivered to the customer after pre-assembly. However, since the pre-assembly process is cumbersome and requires accurate coordination, the current process of pre-assembly of the clamp is still mainly based on manual assembly.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figures 1 to 6 In the embodiment of the present invention, the automatic assembly machine for fire-fighting clamps includes an operating table 1 and a clamp structure 4; a rotating base 13 is provided on the operating table 1, and a primary assembly structure 3 and a secondary assembly structure 5 are respectively installed on both sides of the rotating base 13; the primary assembly structure 3 includes a primary assembly table slidably connected to the rotating base 13

[0029] During the process of the secondary assembly table 51 being fastened to the primary assembly table 31, the clamping structure 6 will clamp the pipe sleeve 41, and the pipe sleeve 41 cannot fall off, and the blocked screw 43 cannot fall off at the same time, until they are fully fastened and the two pipe sleeves 41 form the clamp structure 4, the transmission structure 2 will open the secondary assembly table 51 upward again and return to its original position, and will also take the clamp structure 4 into the secondary assembly groove 513. After the secondary assembly table 51 is reset, the clamping structure 6 will automatically open, and the assembled clamp structure 4 can be taken out therefrom.

[0030] The clamp structure 4 in the device is only used as an auxiliary structure for installation and display, and is not a restrictive structure. Various two-piece clamp structures 4 of the same type and quality can be assembled using the device. The device does not restrict the loading and unloading structures. The pipe sleeve 41, sealing gasket 42, screw 43 and nut 44 can be loaded using a transmission belt, a mechanical arm, a loading vibration plate, etc., or manually, and then the device completes the automatic assembly.

[0031] As another embodiment of the present invention, please refer to Figure 4 The clamp structure 4 is formed by two semicircular pipe sleeves 41 in opposite directions, the sealing gasket 42 is located inside the pipe sleeve 41, and the two ends of the pipe sleeve 41 are respectively installed with hanging ears 411, and the hanging ears 411 are provided with mounting holes 412. The screw 43 passes through the mounting holes 412 on the two pipe sleeves 41, and the screw 43 is installed with a nut 44. The screw 43 and the nut 44 are used to buckle the two semicircular pipe sleeves 41 into a circle. The two ends of the pipe sleeve 41 should also be provided with a counter-positioning buckling structure for positioning. The internal sealing gasket 42 is used to seal the pipe sleeve 41, and the pipe sleeve 41 is used for external reinforcement.

[0032] See also Figure 1 and Figure 3 The first-level assembly table 31 has an installation slot 312 inside, the placement tube 32 is connected to the extension tube 321, and the end of the extension tube 321 inserted into the installation slot 312 is installed with a driven gear 322. A plurality of mutually meshing transmission gears 33 are rotatably installed in the installation slot 312, and the transmission gear 33 connects two driven gears 322. A first-level motor 34 is installed in the installation slot 312, and the first-level motor 34 is connected to a driving gear 35, and the driving gear 35 is meshed and connected with the driven gear 322. The first-level motor 34 drives the driving gear 35, and through the cooperation of the transmission gear 33 and the driven gear 322, the two placement tubes 32 can be rotated synchronously, and the internal nut 44 is quickly screwed on the screw 43, and gradually rises, and finally separated from the placement tube under the drive of the clamp structure 4.

[0033] See also Figure 1 and Figure 3, a baffle 14 located outside the primary assembly platform 31 is vertically installed on the operating table 1, and the primary assembly platform 31 is slidably connected to the baffle 14. A support column 12 is arranged at one end of the operating table 1 away from the baffle 14, and the secondary assembly table 51 is in pressure contact with the support column 12. A plurality of support legs 11 are installed outside the operating table 1. The baffle 14 cooperates with the rotating base 13 to limit the moving track of the primary assembly platform 31. Since the secondary assembly platform 51 is fastened to the primary assembly platform 31 by rotation, when there is only a small angle between the secondary assembly platform 51 and the primary assembly platform 31, the screw 43 extending downward may hit the edge of the placement tube and cannot be inserted. Therefore, the primary assembly platform 31 is set as a liftable structure, which can leave a certain height space when the secondary assembly platform 51 is fastened, and the primary assembly platform 31 is raised again after fastening, so that the screw 43 can be stably inserted into the placement tube. The support legs 11 provide support for the operating table 1, and the support columns 12 are used to support the secondary assembly platform 51, so that the secondary assembly platform 51 is stable in a horizontal position after opening.

[0034] See also Figure 1 and Figure 3 The lifting structure 7 includes a roller 74. The operating table 1 is provided with two rows of hinge seats 76 respectively located on both sides of the primary assembly platform 31. A plurality of mutually parallel support rods 75 are installed on the hinge seats 76. The roller 74 is connected between the support rod 75 and the corresponding support rod 75 on another row of hinge seats 76. The support rod 75 and each support rod 75 in the same row are connected with a cross bar 73. Under the action of the cross bar 73, each support rod 75 will maintain the same rotation angle, that is, the height of each roller 74 is consistent. The roller 74 provides support for the primary assembly platform 31 to adjust the height.

[0035] See also Figure 1 and Figure 3 The lifting structure 7 includes a lever 72, which is connected obliquely to a support rod 75 on the operating table 1 near the baffle 14. A pressure rod 71 is connected between the levers 72. A pressure block 511 is provided on the outside of the secondary assembly platform 51. The horizontal distance between the pressure block 511 and the rotating base 13 is equal to the horizontal distance between the pressure rod 71 and the rotating base 13. The lever 72 is connected obliquely to the support rod 75, and the lever 72 is located outside the baffle 14. When the secondary assembly platform 51 is buckled on the primary assembly platform 31, the originally tilted pressure rod 71 is pressed downward by the pressure block 511, and the lever 72 drives the support rod 75 to rotate, and the primary assembly platform 31 is lifted, so that the various parts of the clamp structure 4 can be spliced ​​together for automatic assembly.

[0036] See also Figure 1 , Figure 2 , Figure 5 and Figure 6The secondary assembly table 51 is provided with a through slot 516 in the middle of the secondary assembly slot 513. The clamping structure 6 includes two clamping plates 68 symmetrically installed in the through slot 516. One end of the clamping plate 68 is connected to the inner wall of the through slot 516, and the other end is inserted into the secondary assembly slot 513. A connecting rod 66 is rotatably installed in the middle of the clamping plate 68. A connecting plate 67 passing through the through slot 516 is connected between the connecting rods 66. The connecting plate 67 is connected to the sliding sleeve 64. The clamping plates 68 are symmetrically located on both sides of the secondary assembly slot 513. When the pipe sleeve 41 is placed in the secondary assembly slot 513, the clamping plates 68 can clamp the pipe sleeve 41 from both sides to prevent the pipe sleeve 41 from falling.

[0037] See also Figure 1 , Figure 2 , Figure 5 and Figure 6 A support shaft 131 is installed on the rotating base 13, and an ear plate 52 connected to the support shaft 131 is installed on the secondary assembly table 51. An inclined adjustment rod 61 is connected to the support shaft 131 through a torsion spring 62. The adjustment rod 61 is obliquely inserted into the area between the secondary assembly table 51 and the operating table 1. The adjustment rod 61 is connected to the sliding rod 63. A groove 515 is opened on the secondary assembly table 51, and an auxiliary rod 65 is obliquely installed in the groove 515. The sliding rod 63 is connected to the auxiliary rod 65, and the sliding rod 63 passes through the sliding sleeve 64. The support shaft 131 limits the rotation track of the secondary assembly platform 51, the adjustment rod 61 is connected to the slide rod 63, the slide rod 63 passes through the sliding sleeve 64, and the adjustment rod 61 is also limited by the torsion spring 62. During the rotation of the secondary assembly platform 51, the slide rod 63 drives the adjustment rod 61 to rotate accordingly, and the pressure of the torsion spring 62 on the adjustment rod 61 gradually increases, causing the slide rod 63 to passively increase the distance between the secondary assembly platform 51, and then pull the sliding sleeve 64 outward to clamp the pipe sleeve 41 in the secondary assembly platform 51. That is, the clamping structure 6 of the device does not clamp when the secondary assembly platform 51 is in a horizontal state. As the secondary assembly platform 51 turns over, the pipe sleeve 41 is gradually clamped to prevent the pipe from falling. After a clamp structure 4 is assembled, the clamp structure 4 can be driven into the secondary assembly platform 51, and the clamping effect is automatically released after the secondary assembly platform 51 is reset, so that the assembled clamp structure 4 can be directly taken out by the unloading equipment or manually. It should be noted that, due to the limited installation space, the length of the adjusting rod 61 in the device is slightly larger than the length of the auxiliary rod 65. Therefore, as the adjusting rod 61 rotates, the sliding rod 63 cannot always remain parallel to the ground of the secondary assembly table 51. However, since the inclination angle generated on the length scale of the sliding rod 63 is very small, and the order of magnitude of the distance change generated is larger, the slight change in the inclination angle can be ignored and the shape of the clamping structure 6 can be controlled by the sliding rod 63.

[0038] See also Figure 1 and Figure 2 The transmission structure 2 includes a driving ring 21 passing through the operating table 1, and a semi-circular gear ring 211 is provided on one side of the driving ring 21. An extension block 512 is connected to the outside of the secondary assembly table 51, and the extension block 512 is connected to one side of the driving ring 21. A track groove 15 that wraps the driving ring 21 is provided on the side of the operating table 1 away from the rotating base 13. A secondary motor 23 is installed on the operating table 1, and the secondary motor 23 is connected to the driving gear 22, and the driving gear 22 is meshed and connected with the gear ring 211. The driving ring 21 is partially located on the surface of the operating table 1, and the other part is located below the operating table 1. The secondary motor 23 drives the driving ring 21 to rotate through the driving gear 35, which will pull the secondary assembly table 51 to rotate, and realize the function of flipping and resetting the secondary assembly table 51. The transmission structure 2 used in the present device is only an illustrative structure and is not regarded as a restrictive description of the transmission structure 2. In addition to using a large drive ring 21, structures such as a screw sleeve or a crank rocker can also be used, or a new motor can be directly added to the ear plate 52 to achieve the control effect of the secondary assembly table 51.

[0039] The working principle of the present invention is:

[0040] The device is provided with a rotating base on the operating table 1, a primary assembly table 31 is vertically installed on one side of the rotating base, and a secondary assembly table 51 is rotatably installed on the other side. A pair of nuts 44 and a pipe sleeve 41 are placed on the primary assembly table 31, a pair of screws 43 and a pipe sleeve 41 are placed on the secondary assembly table 51, and then the secondary assembly table 51 is rotated and buckled on the primary assembly table 31, and the nut 44 is driven by the placement tube 32 inside the primary assembly table 31, and the nut 44 is tightened on the screw 43, so that the preliminary assembly of a clamp structure 4 can be completed.
