[0005] The utility model discloses a large-mass load-bearing three-axis cantilever screw rod module. When the three-axis cantilever module is used in the glue dispensing industry, since the glue cylinders of the glue dispensing are of different sizes, it is necessary to constantly replace the brackets suitable for the size of the glue dispensing cylinders, and the frequent replacement of the brackets is too cumbersome.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A large-mass load-bearing three-axis cantilever screw module comprises an X-axis slide rail, a first slide plate is slidably connected to the front side of the X-axis slide rail, a bracket mechanism is installed on the front side of the first slide plate, and the bracket mechanism is used to install glue dispensing tubes of different sizes; the bracket mechanism comprises a frame installed on the front side of the first slide plate, the upper and lower ends of the frame are provided with mounting holes, the upper and lower ends of the frame are connected to hollow cylinders, a plurality of groups of springs are equidistantly connected to the inner wall of the hollow cylinder, and a first arc-shaped clamping plate is connected to the side of the spring close to the center of the hollow cylinder.

[0008] According to a further technical solution, a second slide plate is fixedly connected to the rear side of the X-axis slide rail, and a Y-axis slide rail is slidably connected to the rear side of the second slide plate.

[0009] The second slide plate slides on the Y-axis slide rail to ensure that the X-axis slide rail moves left and right.

[0010] According to a further technical solution, a third slide plate is fixedly connected to the left side of the lower end of the Y-axis slide rail, and a Z-axis slide rail is slidably connected to the lower end of the third slide plate.

[0011] The third slide plate slides on the Z-axis slide rail to ensure that the Y-axis slide rail moves forward and backward.

[0012] According to a further technical solution, bolts are threadedly connected at upper and lower ends of the frame and the first slide plate.

[0013] The frame and the first slide plate are fixed by setting bolts to ensure that the X-axis slide rail drives the bracket mechanism to move up and down.

[0014] A further technical solution is that a screw is connected to the middle bearing inside the frame, a knob is fixedly connected to the right side of the screw, connecting rods are threadedly connected to the left and right ends of the outer surface of the screw, and a second arc-shaped clamping plate is connected to the side of the connecting rod close to the vertical central axis of the frame.

[0015] The screw is driven to rotate by turning the knob. Since the threads on the left and right outer surfaces of the screw rotate in opposite directions, the connecting rod moves in opposite directions when the screw rotates. The dispensing cylinder is stably clamped by the second arc-shaped clamping plate, which has a secondary fixing effect.

[0016] Compared with the prior art, it has the following improvements and advantages:

[0017] By inserting the dispensing cylinder that needs to be replaced from the mounting hole at the upper end of the frame, the first arc-shaped clamping plate contacts the outer wall of the dispensing cylinder, and the dispensing cylinder is initially clamped and fixed under the extrusion of the spring. Therefore, through the contraction characteristics of the spring and the action of the first arc-shaped clamping plate, the interior of the hollow cylinder can adapt to the installation of dispensing cylinders of different sizes without the need to frequently replace the frame.

[0018] Other features and advantages of the present invention will be described in detail in the subsequent specific implementation section. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In this embodiment, when replacing the glue dispensing cylinder on the bracket mechanism 3, since the size of the glue dispensing cylinder is too large, it is necessary to remove the bolt 8 and replace the frame 301. Frequent disassembly and assembly of the frame 301 is too cumbersome, so the replaced large glue dispensing cylinder is inserted from the mounting hole 302 at the upper end of the frame 301 by hand, and then enters the interior of the upper hollow cylinder 303. The first arc-shaped clamping plate 305 expands outward under the action of contacting with the outer wall of the large glue dispensing cylinder, and the spring 304 contracts. After the glue dispensing cylinder passes through the upper hollow cylinder 303, it enters the lower Inside the hollow cylinder 303 at the end, the first curved splint 305 also expands outward under the action of contact with the outer wall of the large dispensing cylinder, and penetrates the lower hollow cylinder 303. At this time, the hand is released from the dispensing cylinder, and the dispensing cylinder is initially clamped and fixed under the action of the spring 304 squeezing the first curved splint 305. Therefore, through the contraction characteristics of the spring 304 and the action of the first curved splint 305, the inside of the hollow cylinder 303 can adapt to the installation of dispensing cylinders of different sizes without the need to frequently replace the frame 301.

To ensure stable glue dispensing of the glue dispensing tube during operation, the screw rod 9 is driven by rotating the knob 10 to cause the connecting rod 11 to move inward synchronously. The synchronously displaced connecting rod 11 can ensure symmetrical movement of the second arc-shaped clamping plate 12, and the clamping position is always maintained in the middle. At this time, the connecting rod 11 drives the second arc-shaped clamping plate 12 to perform secondary clamping and fixation on the outer surface of the glue dispensing tube, thereby improving the stability of the glue dispensing tube during operation.

Frequent disassembly and assembly of the frame 301 is too cumbersome, so the replacement large dispensing cylinder is inserted from the mounting hole 302 at the upper end of the frame 301 by hand, and then enters the interior of the upper hollow cylinder 303. The first arc-shaped clamping plate 305 expands outward under the action of contacting with the outer wall of the large dispensing cylinder, and the spring 304 contracts. After the dispensing cylinder passes through the upper hollow cylinder 303, it enters Into the lower hollow cylinder 303, similarly the first arc-shaped clamping plate 305 expands outwards under the action of contact with the outer wall of the large dispensing cylinder, and penetrates the lower hollow cylinder 303. At this time, release your hand from the dispensing cylinder, and the dispensing cylinder is initially clamped and fixed under the action of the spring 304 squeezing the first arc-shaped clamping plate 305. Therefore, through the contraction characteristics of the spring 304 and the action of the first arc-shaped clamping plate 305, the interior of the hollow cylinder 303 can adapt to the installation of dispensing cylinders of different sizes without the need to frequently replace the frame 301.
