[0066] like Figures 1 to 10 As shown, the present embodiment provides a crimping machine, which includes a frame 1, a turntable assembly 2 and a plurality of crimping fixtures 3. The turntable assembly 2 includes a first driving member 21, a chassis 22 and a turntable 23. The chassis 22 is fixedly mounted on the frame 1, and the turntable 23 is rotatably mounted on the chassis 22 around a vertical line. A first through hole is provided in the middle of the turntable 23. The turntable 23 is also provided with a plurality of arc grooves 231 equidistantly spaced around the circumference of the first through hole, one end of the arc groove 231 is close to the first through hole, and the other end of the arc groove 231 is away from the first through hole. The output end of the first driving member 21 is connected to the turntable 23; a plurality of crimping fixtures 3 are radially slidably arranged on the chassis 22, and the plurality of crimping fixtures 3 correspond one-to-one to the plurality of arc grooves 231, and one end of the crimping fixture 3 is penetrated through the arc groove 231.

[0067] Specifically, when the workpiece 100 needs to be crimped, the workpiece 100 is placed in the middle of the first through hole, and the first driving member 21 drives the turntable 23, and the turntable 23 rotates around a vertical line. Since one end of the crimping tool 3 is passed through the arc groove 231, when the turntable 23 rotates around the vertical line, the turntable 23 can drive multiple crimping tools 3 to slide synchronously in the radial direction close to the workpiece 100, and finally the workpiece 100 is crimped synchronously, thereby ensuring the consistency of the actions of multiple crimping tools 3 and improving the assembly accuracy.

[0068] In this embodiment, the arc center of the arc groove 231 is away from the center of the turntable 23. When the crimping tool 3 abuts against the end of the arc groove 231 close to the first through hole, the crimping tool 3 is closest to the central axis of the turntable 23. When the crimping tool 3 abuts against the end of the arc groove 231 far from the first through hole, the crimping tool 3 is farthest from the central axis of the turntable 23.

[0069] In this embodiment, only one first driving member 21 is needed to enable multiple crimping tools 3 to synchronously crimp the workpiece 100 . The number of first driving members 21 is small, and the cost is low.

[0070] Optionally, the number of the buckling tools 3 is more than 3, such as 3, or 4, or 5, or even more. In this embodiment, the number of the buckling tools 3 is 8.

[0071] In this embodiment, the workpiece 100 includes a buckle ring and a bladder skin, the buckle ring is arranged on the periphery of the bladder skin, and the buckling tool 3 is used to buckle the buckle ring to the bladder skin. In some other embodiments, the workpiece 100 can be other products.

[0072] Optionally, a top cover of the frame 1 is provided with a protective cover, and the protective cover is used to isolate and protect the turntable assembly 2 and the crimping tool 3.

[0073] Optionally, a connecting plate 232 is provided on the periphery of the turntable 23, and the connecting plate 232 is provided with a slide groove extending radially along the turntable 23. The output end of the first driving member 21 is provided with a transmission member 24, and the transmission member 24 is slidably inserted in the slide groove.

[0074] In this embodiment, the first driving member 21 is a motor, and a linear transmission mechanism such as a screw-nut pair is provided at the output end of the motor. A slide rail is horizontally arranged on the top of the frame 1, and the extension direction of the slide rail is parallel to the tangent of the turntable 23. The transmission member 24 includes a U-shaped groove member and a slide rod. The U-shaped groove member is installed on the slide rail through a slider, and the U-shaped groove member is transmission-connected to the linear transmission mechanism. The connecting plate 232 extends into the groove of the U-shaped groove member, and the slide rod is installed on the U-shaped groove member and slidably inserted in the slide groove. When the first driving member 21 drives the linear transmission mechanism, the linear transmission mechanism pushes the slide rod through the U-shaped groove member, and the slide rod slides in the slide groove of the connecting plate 232 and simultaneously moves the connecting plate 232, so that the turntable 23 rotates around a vertical line.

[0075] In some other embodiments, the first driving member 21 is a cylinder.

[0076] Optionally, the crimping tool 3 includes a crimping seat 31, a second driving member 33 and a crimping flap clamp 34. The crimping seat 31 is radially slidably installed on the chassis 22. The crimping seat 31 is installed with a force bearing 32, and the force bearing 32 is slidably set in the arc groove 231; the second driving member 33 is installed on the crimping seat 31; the crimping flap clamp 34 is connected to the output end of the second driving member 33, and the second driving member 33 is used to drive the crimping flap clamp 34 radially close to or away from the workpiece 100.

[0077] A force bearing 32 is arranged in the arc groove 231. When the turntable 23 rotates, the turntable 23 drives the force bearing 32, and the force bearing 32 slides in the arc groove 231. At the same time, the force bearing 32 drives the buckling seat 31 to slide radially. When the buckle flap clamp 34 abuts against the buckle ring, the second driving member 33 drives the buckle flap clamp 34 to further apply pressure to the buckle ring to ensure that the buckle ring can be stably buckled on the bag skin.

[0078] Optionally, a displacement sensor is provided on one side of each crimping tool 3 , and the displacement sensor is used to detect the displacement of the crimping clamp 34 .

[0079] Optionally, the crimping tool 3 also includes a mounting block 35, a first spring 36 and a steel ball 37. The mounting block 35 is connected to the output end of the second driving member 33.

The crimping clamp 34 is provided with an end of a limiting groove 341 which is inserted into the mounting channel, and the first spring 36 pushes the steel ball 37 to be embedded in the limiting groove 341.

[0080] When one end of the flap clamp 34 is inserted into the installation channel, the first spring 36 pushes the steel ball 37 to be embedded in the limiting groove 341 to prevent the flap clamp 34 from being separated from the mounting block 35 during the buckling process. When the flap clamp 34 needs to be replaced, the flap clamp 34 is pulled away from the mounting block 35, the steel ball 37 slides out of the limiting groove 341, and the flap clamp 34 is separated from the mounting block 35.

The port diameter of the mounting hole close to one end of the mounting channel is smaller than the diameter of the steel ball 37.

[0082] Since the port diameter of the mounting hole close to one end of the mounting channel is smaller than the diameter of the steel ball 37, when the buckle clamp 34 is detached from the mounting block 35, the steel ball 37 will not fall completely into the mounting channel; when the first spring 36 or the steel ball 37 needs to be replaced, the first spring 36 and the steel ball 37 in the mounting hole can be removed by removing the limit plate 38.

[0084] When it is necessary to crimp the workpiece 100, place the workpiece 100 on the positioning tool 5 and install the positioning tool 5 on the output end of the lifting component 4. The lifting component 4 drives the positioning tool 5 and the workpiece 100 to rise, and the workpiece 100 passes through the second through hole and comes to the center of the turntable 23; when it is necessary to replace the flap clamp 34, remove the positioning tool 5 on the lifting component 4, install the replacement tool 6 on the output end of the lifting component 4, and use the lifting component 4 to drive the replacement tool 6 to rise, and the replacement tool 6 passes through the second through hole and comes to the center of the turntable 23, the flap clamp 34 on the crimping tool 3 can be inserted into the replacement tool 6, and the flap clamp 34 on the crimping tool 3 is removed.
