Description

Technical Field

[0001] This utility model relates to the technical field of mechanical assembly tools, and in particular to a multi-bolt synchronous tightening device. Background Technology

[0002] Screws on home appliance assembly lines need to be tightened using tightening devices. Tightening devices are electric wrench tools based on servo control systems, mainly used for automated tightening of fasteners such as bolts and nuts in industrial assembly scenarios.

[0003] Existing tightening devices typically use servo motors to drive several sleeves to simultaneously tighten multiple bolts for automatic assembly. Automated assembly of bolted connections can save manpower and is highly efficient, representing the future direction of assembly operations.

[0004] However, when using several sleeves to tighten multiple bolts simultaneously, since the sleeves are fixed to the slide by bolts, it is not possible to quickly change the sleeves according to the screws on different mechanical equipment. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, this utility model proposes a multi-bolt synchronous tightening device, which allows for the simultaneous tightening of multiple bolts on mechanical equipment by changing the sleeve according to the bolt position. The operating plate drives the connecting plate to move in the movable slot, and the movable plate moves along the round rod and compresses the spring, inserting the sleeve into the placement slot, where it is initially fixed by a magnetic block and magnetic groove. The operating plate is then released, and the spring elastically drives the movable plate, causing locking rod one to insert into locking hole one of the sleeve. Locking rod two passes through the operating plate and is threadedly connected to locking hole two for locking. A motor drives the threaded rod, causing the threaded sleeve plate and fixed sleeve plate to move downwards, bringing the tightening mechanism closer to the bolts for rapid synchronous tightening.

[0007] To achieve the above objectives, this utility model proposes a multi-bolt synchronous tightening device, including a worktable. A tightening mechanism for tightening bolts is disposed above the worktable. A lifting device for driving the tightening mechanism to move up and down is disposed at the top of the worktable. A self-locking device for locking the tightening mechanism is disposed within the tightening mechanism. Support legs for supporting the worktable are fixedly installed at the bottom of the worktable. The lifting device includes a support assembly disposed above the worktable for supporting the tightening mechanism. A lifting assembly for driving the support assembly to move up and down is disposed at the top of the worktable. The tightening mechanism includes a rotating assembly disposed on the support assembly for rotation. A tightening assembly for tightening bolts is disposed within the rotating assembly. The self-locking device includes a locking assembly disposed within the rotating assembly for locking the tightening assembly. A reset assembly for driving the locking assembly to lock the tightening assembly is disposed within the rotating assembly.

[0008] In addition, the multi-bolt synchronous tightening device proposed in this application may also have the following additional technical features: Specifically, the lifting assembly includes a fixed plate fixedly installed on the top of the workbench, a threaded rod for driving the support assembly to move up and down is provided in the fixed plate, a motor for driving the threaded rod to rotate is fixedly installed at the top of the threaded rod, and a guide rod for allowing the support assembly to move up and down is provided in the fixed plate.

[0009] Specifically, the support assembly includes a threaded sleeve plate disposed within a fixed plate for threaded connection with a threaded rod, a support plate for supporting the rotating assembly being fixedly installed at the front end of the threaded sleeve plate, and a fixed sleeve plate for fitting onto a guide rod being fixedly installed at the rear end of the support plate.

[0010] Specifically, the rotating assembly includes a rotating disk mounted on a support plate for rotation. The top of the rotating disk has a moving groove for sliding the locking assembly. The top of the rotating disk has a locking hole for locking the locking assembly. The bottom of the rotating disk has a placement groove for placing the tightening assembly. The top of the placement groove has a magnetic suction groove.

[0011] Specifically, the tightening assembly includes a sleeve inserted into the placement groove for tightening the bolt, a locking hole is provided on the rod of the sleeve, and a magnetic block for magnetic connection with the magnetic slot is fixedly installed at the top of the sleeve.

[0012] Specifically, the reset assembly includes a round rod fixedly installed in the movable groove, and a spring for driving the locking assembly to be inserted into the locking hole is fitted on the rod body.

[0013] Specifically, the locking assembly includes a movable plate mounted on a round rod for movement. A locking rod is fixedly installed at the end of the movable plate away from the round rod for insertion into a locking hole. A connecting plate is fixedly installed at the top of the movable plate. An operating plate for driving the movable plate to move is fixedly installed at the top of the connecting plate. A locking rod is provided on the operating plate for locking the operating plate.

[0014] Compared with the prior art, the beneficial effects of this application are as follows: By incorporating a lifting device, tightening mechanism, and self-locking device, the sleeve is changed according to the bolt position when simultaneously tightening multiple bolts on mechanical equipment. The operating panel drives the connecting plate to move in the moving slot, and the movable plate moves along the round rod and compresses the spring, inserting the sleeve into the placement slot, where it is initially fixed by the magnetic block and magnetic groove. The operating panel is then released, and the spring elastically drives the movable plate, causing locking rod one to be inserted into locking hole one of the sleeve. Locking rod two is threaded through the operating panel and locked into locking hole two. The motor drives the threaded rod, causing the threaded sleeve plate and fixed sleeve plate to move downwards, bringing the tightening mechanism closer to the bolts for rapid synchronous tightening.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0019] The following description, in conjunction with the accompanying drawings, describes a multi-bolt synchronous tightening device according to an embodiment of the present invention.

The lifting device 200 includes a support leg 300 provided above the workbench 100 for supporting the tightening mechanism 300. The support assembly 220 provides support for the 0. The top of the worktable 100 is provided with a lifting assembly 210 for driving the support assembly 220 to move up and down. The tightening mechanism 300 includes a rotating assembly 320 disposed on the support assembly 220 for rotation. A tightening assembly 310 for tightening bolts is disposed inside the rotating assembly 320. The self-locking device 400 includes a locking assembly 410 disposed inside the rotating assembly 320 for locking the tightening assembly 310. A reset assembly 420 for driving the locking assembly 410 to lock the tightening assembly 310 is disposed inside the rotating assembly 320.

[0021] In one embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the lifting assembly 210 includes a fixed plate 211 fixedly installed on the top of the worktable 100, and the fixed plate 211 is welded to the top of the worktable 100; a threaded rod 212 for driving the support assembly 220 to move up and down is provided in the fixed plate 211, wherein the upper and lower ends of the threaded rod 212 are connected to the fixed plate 211 and the worktable 100 through bearings to facilitate the rotation of the threaded rod 212; a motor 213 for driving the threaded rod 212 to rotate is fixedly installed on the top of the threaded rod 212, and a guide rod 214 for allowing the support assembly 220 to move up and down is provided in the fixed plate 211.

[0022] Furthermore, the support assembly 220 includes a threaded sleeve 222 disposed within the fixed plate 211 for threaded connection with the threaded rod 212. A support plate 221 for supporting the rotating assembly 320 is fixedly installed at the front end of the threaded sleeve 222, and a fixed sleeve 223 for fitting onto the guide rod 214 is fixedly installed at the rear end of the support plate 221. Therefore, when it is necessary to tighten the bolts on the mechanical equipment, the threaded rod 212 can be driven to rotate by the motor 213, which will cause the threaded sleeve 222 to move downward along the threaded rod 212. At the same time, the fixed sleeve 223 moves downward along the guide rod 214, which will drive the tightening mechanism 300 on the support plate 221 to approach the bolts, thus enabling multiple bolts to be tightened simultaneously in a fast manner.

[0023] In one embodiment of this utility model, such as Figure 4 and Figure 5 As shown, the rotating assembly 320 includes a rotating disk 321 mounted on the support plate 221 for rotation. The rotating disk 321 can be connected to an external rotating mechanism, thus facilitating the rotation of the rotating disk 321. The top of the rotating disk 321 has a moving groove 322 for sliding the locking assembly 410. The top of the rotating disk 321 has a locking hole 323 for locking the locking assembly 410. The bottom of the rotating disk 321 has a placement groove 324 for placing the tightening assembly 310. The top of the placement groove 324 has a magnetic suction groove 325.

[0024] Furthermore, the tightening assembly 310 includes a sleeve 311 inserted into the placement groove 324 for tightening the bolt. The sleeve 311 has a locking hole 312 on its rod. A magnetic block 313 for magnetic connection with the magnetic groove 325 is fixedly installed at the top of the sleeve 311. Therefore, the initial fixation of the sleeve 311 can be achieved by utilizing the magnetic connection between the magnetic block 313 and the magnetic groove 325.

[0025] In one embodiment of this utility model, such as Figure 5 and Figure 6 As shown, the reset assembly 420 includes two round rods 421 fixedly installed in the moving groove 322, and the two round rods 421 are symmetrically distributed in the moving groove 322; a spring 422 for driving the locking assembly 410 to be inserted into the locking hole 312 is fitted on the rod body of the round rod 421.

[0026] Furthermore, the locking assembly 410 includes a movable plate 412 fitted onto the round rod 421 for movement. A locking rod 411 for insertion into the locking hole 312 is fixedly mounted at one end of the movable plate 412 away from the round rod 421. A connecting plate 413 is fixedly mounted at the top of the movable plate 412, and an operating plate 414 for driving the movable plate 412 to move is fixedly mounted at the top of the connecting plate 413. A second locking rod 415 for locking the operating plate 414 is provided on the plate body of the operating plate 414. 5. The threaded connection between the operating plate 414 and the locking hole 323 can lock the operating plate 414. When the sleeve 311 needs to be replaced, the locking rod 415 can be loosened and removed. Then, the operating plate 414 can be used to drive the connecting plate 413 to move in the moving groove 322. At the same time, the movable plate 412 can be moved along the round rod 421 and the spring 422 fitted on the round rod 421 can be compressed. The sleeve 311 can be quickly removed from the placement groove 324 and replaced.

[0027] In summary, this utility model embodiment of a multi-bolt synchronous tightening device allows for the replacement of sleeves 311 based on the positions of multiple bolts on a mechanical device when multiple bolts need to be tightened simultaneously. The operating plate 414 drives the connecting plate 413 to move within the moving groove 322, while simultaneously moving the movable plate 412 along the round rod 421, compressing the spring 422 mounted on the round rod 421. The sleeves 311 are then inserted into the placement groove 324, and the magnetic connection between the magnetic block 313 at the top of the sleeve 311 and the magnetic groove 325 initially fixes the sleeves 311 within the placement groove 324. Releasing the force on the operating plate 414 compresses the spring 422 mounted on the round rod 421, and under the elastic action of the spring 422, the bolts can be tightened simultaneously. Moving the movable plate 412 along the round rod 421 allows the locking rod 411 on the movable plate 412 to be inserted into the locking hole 312 on the sleeve 311. The locking rod 415 then passes through the operating plate 414 and is threadedly connected to the locking hole 323 to lock the operating plate 414. The motor 213 drives the threaded rod 212 to rotate, causing the threaded sleeve 222 to move downwards along the threaded rod 212. Simultaneously, the fixed sleeve 223 moves downwards along the guide rod 214, driving the tightening mechanism 300 on the support plate 221 to approach the bolts. This allows for the rapid and simultaneous tightening of multiple bolts. This solves the problem that because several sleeves 311 are fixed to the slide by bolts, it is impossible to quickly replace the sleeves 311 according to the screws on different mechanical equipment.
