Description

Technical Field

[0001] The invention relates to the technical field of assembly tooling, in particular to an assembly tooling for a metal braided pipe joint. Background Art

[0002] Metal braided hoses are often used in high-pressure applications, especially hydraulic applications. The metal braid provides additional strength to the hose, allowing it to withstand higher hydraulic pressures. The braid allows the individual wires to move relative to each other despite the use of metal wires, giving the hose a high degree of flexibility.

[0003] Among them, in the water heating systems of homes and commercial buildings, metal braided pipes are widely used to connect faucets, water heaters, toilets and other equipment. It can withstand a certain amount of water pressure, and at the same time has good flexibility, which is convenient for installation and maintenance. The metal braided pipe has good sealing performance, which can effectively prevent water leakage and ensure the normal operation of the water heating system. In the water heating systems of some high-end hotels and office buildings, higher requirements are placed on the sealing and reliability of the pipes, and metal braided pipes have become the preferred connection pipe fittings.

[0004] After the existing Teflon sleeve is cut, the braided mesh at the cut end will explode. However, when installing two sections of Teflon tubes, a connector needs to be installed on one end. At this time, since the end of the Teflon sleeve is exploded, it is inconvenient to install the connector. The method of manually tidying up the exploded end is relatively cumbersome, which makes the work efficiency low. On the other hand, in the prior art, when assembling the metal braided tube and the joint, most of the braided tubes cannot be properly supported, and excessive stress caused by vibration or pressure changes may affect the use and the assembly effect.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a metal braided pipe joint assembly tool is provided to achieve a more practical purpose. Summary of the invention

Specifically, in this embodiment, when assembling the metal braided tube and the joint, the third fixture block 216 serves as the first placement platform, and the staff first places the metal braided tube into the fifth placement slot 218 on the third fixture block 216, and then the second clamping cylinders 206 on both sides are started to drive the two second fixture blocks 208 to approach each other, and the metal braided tube is assembled through the third placement slot 212 and the fifth placement slot 218. The tube is positioned, and the metal braided tube can be protected by the arrangement of the first connecting rod 209 and the first spring 210 to prevent it from being clamped or deformed by the second fixture block 208. The specific working process is: the second clamping cylinder 206 is started to drive the push plate 207 to move, and then the second fixture block 208 is driven to move through the first connecting rod 209 and the second pick-and-place groove 219. When the second fixture block 208 clamps the metal braided tube, if the push plate 207 continues to move, the second fixture block 208 will slide relative to the push plate 207 through the first connecting rod 209 and will not continue to approach. When the push plate 207 and the second fixture block 208 are relatively displaced, the first spring 210 is in a compressed state. When the two second fixture blocks 208 are separated from each other, the push plate 207 and the second fixture block 208 are also reset away from each other under the action of the first spring 210, thereby protecting the metal braided tube.

The two ends of the first spring 210 are respectively abutted against the corresponding connecting sleeve 211 and the push plate 207. The connecting sleeve 211 is threadedly connected to the corresponding second fixture block 208. Specifically, through the setting of the connecting sleeve 211, the initial compression amount of the first spring 210 can be adjusted, thereby adjusting the size of the initial force required when the push plate 207 and the second fixture block 208 are relatively displaced to adapt to different assembly tasks.

[0027] See also Figure 5 - Figure 8The pulling mechanism includes a second connecting rod 309 threadedly connected to the end of the second fixture block 208 away from the fourth placement groove 213, a pulling block 307 is slidably connected to the outer side of the second connecting rod 309, and a clamping groove 308 is provided on the side where the pulling blocks 307 on both sides are close to each other, a second spring 310 is sleeved on the outer side of the second connecting rod 309, and the two ends of the second spring 310 are in contact with the second connecting rod 309 and the pulling block 307. A seventh connecting rod 313 is provided between the pulling block 307 and the push plate 207 on the same side, and the end of the seventh connecting rod 313 close to the pulling block 307 is rotatably connected to the first connecting block 311, and the first connecting block 311 is installed on the corresponding pulling block 307, and the end of the seventh connecting rod 313 close to the push plate 207 is rotatably connected to the second connecting block 312, the second connecting block 312 is fixedly connected to the corresponding push plate 207, a sliding connection groove 314 is provided on the side of the pull block 307 close to the push plate 207, the first connecting block 311 is slidably connected to the inner side of the corresponding sliding connection groove 314, the pull block 307 is close to one end of the second fixture block 208 and is located above and below the sliding connection groove 314. A positioning rod 316 is slidably connected to the bottom of the inner side of the mounting hole 315, a limiting cap 317 is provided on the top of the positioning rod 316, a limiting step 318 matched with the limiting cap 317 is provided on the inner side of the mounting hole 315, a fourth spring 319 is provided on the top of the limiting cap 317, an adjusting sleeve 320 is sleeved on the top of the fourth spring 319, and both ends of the fourth spring 319 are respectively connected to the adjusting sleeve 3 20 and the limiting cap 317 are abutted, the adjusting sleeve 320 is threadedly connected to the inner side of the corresponding mounting hole 315, and the upper and lower end surfaces of the first connecting block 311 are provided with positioning grooves adapted to the positioning rod 316. Specifically, after the two second fixture blocks 208 clamp the metal braided tube, the second clamping cylinder 206 continues to drive the push plate 207 to move in the direction close to the second fixture block 208. At this time, the second fixture block 208 is stationary, and the positioning rod 316 is inserted in the positioning groove of the first connecting block 311. When the push plate 207 and the second fixture block 208 move relative to each other, the push plate 207 will push the first connecting block 311 to move through the seventh connecting rod 313, so that the first connecting block 311 drives the pull block 307 to move away from the second fixture block 2 08, so that the pull block 307 pulls the metal braided tube, so that the exploded position of the end thereof moves toward the inside of the third placement slot 212, and the exploded part thereof shrinks inwardly and gathers together through the end position of the third placement slot 212, and then the staff places the joint from the second placement slot 219 to the inside of the fourth placement slot 213, and when the push plate 207 continues to drive the pull block 307 to move and the pull block 307 moves away from the second fixture block 208, the second spring 310 will continue to deform and compress, and at this time, the force of the second spring 310 on the pull block 307 gradually increases, and when the force of the second spring 310 on the pull block 307 reaches a certain level, the fourth spring 319 will compress and cause the positioning rod 316 to escape from the positioning slot of the first connecting block 311,At this time, the pull block 307 moves toward the direction close to the second fixture block 208 under the action of the second spring 310, thereby pushing the metal braided tube to move toward the direction close to the joint and inserting its end into the inside of the joint, thereby assisting the assembly work; when the assembly work is completed, the second clamping cylinder 206 will drive the push plate 207 to move. During this process, the first spring 210 will drive the push plate 207 and the second fixture block 208 to move away, and the push plate 207 will drive the first connecting block 311 to move toward the direction close to the positioning rod 316. At this time, the pull block 307 is in contact with the second fixture block 208. When the push plate 207 and the second fixture block 208 are separated to the initial state, the positioning rod 316 is again clamped on the inner side of the positioning groove of the first connecting block 311 to facilitate the next assembly work.

[0028] In this embodiment, the pulling mechanism and the fixture mechanism are integrated together and work in conjunction with each other, which reduces the complexity of the mechanical structure, reduces the difficulty of assembly operations, and reduces costs.

[0029] Specifically, the initial compression amount of the fourth spring 319 can be adjusted by setting the adjustment sleeve 320, thereby adjusting the acting force between the positioning rod 316 and the first connecting block 311 to improve adaptability.

[0030] It should be noted that in actual use, the inner diameter of the clamping groove 308 can be set to be smaller than the inner diameter of the third placement groove 212, or an anti-slip pad can be installed on its inner wall, so that the clamping force of the pull block 307 on the metal braided tube is greater than the clamping force of the second fixture block 208 on the metal braided tube, so as to facilitate the pull block 307 to pull the metal braided tube.

[0031] Embodiment 3 This embodiment discloses the specific structure of the support mechanism, please refer to Figure 3 - Figure 4The supporting mechanism includes a third displacement driving cylinder 401 installed on the top of the work table 101 and located at the end of the fixture mechanism away from the pulling mechanism.

A positioning plate 411 is provided on the outer side of the support plate 410 near the end of the fourth connecting rod 405. Specifically, when it is necessary to support the connection, the third displacement driving cylinder 401 is started to drive the third displacement plate 402 and the third connecting rod 403 to perform displacement movement, so as to achieve The support plate 410 is driven to move toward the direction close to the joint, so that the support plate 410 is inserted into the inner side of the end of the metal braided tube, and then the third displacement driving cylinder 401 continues to drive the support plate 410 to move inward until the positioning plate 411 abuts against the end face of the joint. The joint can be positioned by the abutment between the positioning plate 411 and the joint, without the need for staff operation, thus saving manual labor. Then the third displacement driving cylinder 401 continues to drive the third connecting rod 403 to move, and then drives the fifth connecting rod 407 to move, thereby driving the driving rod 408 to continue to move in the direction away from the guide block 412. At this time, since the support plate 410 can no longer perform the axial displacement movement of the driving rod 408, under the action of the sixth connecting rod 409, when the driving rod 408 is When the moving rod 408 and the support plate 410 are relatively displaced, several support plates 410 will spread outward to support the connection between the end of the braided tube and the joint, thereby facilitating the assembly of the metal braided tube and the joint. When the assembly work is completed, the third displacement driving cylinder 401 is started again to drive the driving rod 408 to move in the direction close to the guide block 412, so that the support plate 410 is pulled out from the inside of the metal braided tube. When the third displacement driving cylinder 401 continues to drive the support plate 410 to move and the positioning plate 411 abuts against the guide block 412, the third displacement driving cylinder 401 continues to drive the driving rod 408 to move so that it is relatively displaced with the support plate 410, thereby causing several support plates 410 to shrink inward and return to their initial state.

[0032] It should be noted that the guide block 412 guides the fourth connecting rod 405, and the arrangement of the third connecting rod 403, the third spring 404, the fourth connecting rod 405 and the connecting groove 406 can protect the joint. When the fourth connecting rod 405 is subjected to a large force during use, the third connecting rod 403 can be relatively displaced with the fourth connecting rod 405 so that it no longer moves forward, thereby preventing the joint from being deformed due to the extrusion of the positioning plate 411.

[0033] Specifically, the working principle of the metal braided pipe joint assembly tool in the first embodiment is as follows: when in use, the first clamping cylinder 202 is started to separate the two first fixture blocks 201, and the staff places the metal braided pipe on the inner side of the first placement groove 203. The first clamping cylinder 202 is started to drive the two first fixture blocks 201 to approach each other and clamp the metal braided pipe. Then, the second displacement drive cylinder 304 is started to drive the second displacement plate 305 and the air claw 306 to approach the direction close to the metal braided pipe, and the tail position of the metal braided pipe is clamped by the air claw 306. Then, the first displacement drive cylinder 302 is started to move the metal braided pipe in the direction away from the first fixture block 201, so that the position where the end thereof explodes moves toward the inner side of the first placement groove 203, and the exploded part thereof shrinks inward and gathers through the end position of the first placement groove 203. Then, the staff places the joint on the inner side of the second placement groove 204. Then, the first displacement drive cylinder 302 is started again to drive the metal braided pipe to move in the direction close to the joint, so that the end thereof is inserted into the inner side of the joint.

[0034] Specifically, the working principle of the metal braided pipe joint assembly tool in the second embodiment is as follows: when in use, the staff first places the metal braided pipe into the fifth placement groove 218 on the third fixture block 216, and then the second clamping cylinders 206 on both sides are started to drive the two second fixture blocks 208 to approach each other, and position the metal braided pipe through the third placement groove 212 and the fifth placement groove 218. After the two second fixture blocks 208 clamp the metal braided pipe, the second clamping cylinder 206 continues to drive the push plate 207 to move toward the second fixture block 208. At this time, the push plate 207 will push the first connecting block 311 to move through the seventh connecting rod 313, so that the pull block 307 pulls the metal braided pipe, so that the exploded position of its end moves toward the inside of the third placement groove 212, and the exploded part is shrunk inward and gathered through the end position of the third placement groove 212. Then the staff places the joint into the inside of the fourth placement groove 213. When the push plate 207 continues to drive the pull block 3 When the second spring 310 is in motion and the pull block 307 is away from the second fixture block 208, the second spring 310 will continue to deform and compress. At this time, the force of the second spring 310 on the pull block 307 gradually increases. When the force of the second spring 310 on the pull block 307 reaches a certain level, the fourth spring 319 will compress so that the positioning rod 316 will be disengaged from the positioning groove of the first connecting block 311. At this time, the pull block 307 moves toward the second fixture block 208 under the action of the second spring 310, thereby pushing the metal braided tube to move toward the direction close to the joint and inserting its end into the inner side of the joint; when the assembly work is completed, the second clamping cylinder 206 will drive the push plate 207 to move, and the push plate 207 will drive the first connecting block 311 to move toward the direction close to the positioning rod 316. At this time, the pull block 307 is in contact with the second fixture block 208. When the push plate 207 and the second fixture block 208 are separated to the initial state, the positioning rod 316 is again clamped on the inner side of the positioning groove of the first connecting block 311 to facilitate the next assembly work; When it is necessary to support the connection, the third displacement drive cylinder 401 is started to drive the third displacement plate 402 and the third connecting rod 403 to move, thereby driving the support plate 410 to move in the direction close to the joint, so that the support plate 410 is inserted into the inner side of the end of the metal braided tube, and then the third displacement drive cylinder 401 continues to drive the support plate 410 to move inward until the positioning plate 411 abuts against the end face of the joint, and then the third displacement drive cylinder 401 continues to drive the third connecting rod 403 to move, thereby driving the fifth connecting rod 407 to move, thereby driving the driving rod 408 to continue to move in the direction away from the guide block 412. At this time, since the support plate 410 can no longer perform the axial displacement movement of the driving rod 408, the sixth connecting rod 409 is Under the action, when the driving rod 408 and the support plate 410 are relatively displaced, several support plates 410 will spread outward, thereby supporting the connection between the end of the braided tube and the joint, thereby facilitating the assembly of the metal braided tube and the joint. When the assembly work is completed, the third displacement driving cylinder 401 is started again to drive the driving rod 408 to move in the direction close to the guide block 412, so that the support plate 410 is pulled out from the inside of the metal braided tube. When the third displacement driving cylinder 401 continues to drive the support plate 410 to move and the positioning plate 411 abuts against the guide block 412, the third displacement driving cylinder 401 continues to drive the driving rod 408 to move so that it is relatively displaced with the support plate 410, thereby causing several support plates 410 to shrink inward and return to their initial state.
