Technical Field

[0001] The utility model relates to the technical field of drum casting rubber, in particular to a drum that is convenient for disassembly and assembly. Background Technique

[0002] The polyurethane casting rubber of the drum adopts the polyurethane hot vulcanization process, which is suitable for high-quality hot vulcanized rubber. The high-performance polyurethane is directly poured and vulcanized on the surface of the drum, so that the drum has extremely strong adhesion and excellent wear resistance.

[0003] Before the drum is cast with rubber, the drum needs to be connected to the machine tool. The machine tool drives the drum to rotate so that the hot vulcanized rubber is evenly covered. At present, most of the connection methods between the drum and the machine tool are flange connections. The prerequisite for flange connection is that the flange on the drum must have the same size as the flange on the machine tool. However, the flange sizes of different-sized drums are also different, and the adaptability is relatively low. The flange on the lathe needs to be replaced with a matching size before installation, which is not convenient to use. Content of the Utility Model

Specific embodiments

[0023] As Figures 1 - 5 shown, the present utility model provides a technical solution: a drum that is convenient for disassembly and assembly, including a drum body 1. Both ends of the drum body 1 are fixedly installed with drum shafts 2. A disassembly and assembly mechanism 3 for conveniently disassembling and assembling the drum body 1 is provided on the drum shafts 2. By setting the disassembly and assembly mechanism 3, the drum body 1 can be installed on the flange of the machine tool. An auxiliary mechanism 4 is provided on the disassembly and assembly mechanism 3. By setting the auxiliary mechanism 4, the positioning block 34 can be accurately positioned, facilitating the installation of the drum body 1 by the staff.

[0024] The above-mentioned disassembly and assembly mechanism 3 includes a positioning disk 31, a rotating disk 32, a threaded rod 33, a positioning block 34, a positioning hole 35, an L-shaped rod 36, an arc-shaped plate 37, an arc-shaped groove 38, a hollow rod 39, a knob 310, a slider 311, and a limit pin 312. The positioning disk 31 is fixedly installed on the outer wall of the roller shaft 2. The inner wall of the positioning disk 31 is slidably connected to the positioning block 34. The positioning block 34 is provided with a positioning hole 35. By sliding the positioning block 34, the distance between the positioning hole 35 and the roller shaft 2 can be adjusted, so that the position of the positioning hole 35 can be adjusted according to the position of the flange mounting hole on the machine tool to adapt to the flange on the machine tool. The outer wall of the positioning block 34 is fixedly installed with an L-shaped rod 36. The rotating disk 32 is rotatably connected to the inner wall of the positioning disk 31. The side wall of the rotating disk 32 is fixedly installed with an arc-shaped plate 37. The arc-shaped plate 37 is provided with an arc-shaped groove 38. The outer wall of the L-shaped rod 36 fits on the inner wall of the arc-shaped groove 38. When the rotating disk 32 rotates, it will drive the arc-shaped plate 37 to rotate synchronously. During the rotation of the arc-shaped plate 37, the arc-shaped groove 38 will squeeze the L-shaped rod 36, causing the L-shaped rod 36 to drive the positioning block 34 to slide on the inner wall of the positioning disk 31. The side wall of the rotating disk 32 is fixedly installed with a hollow rod 39. One end of the threaded rod 33 is rotatably connected to the inner wall of the positioning disk 31. The other end of the threaded rod 33 penetrates through the positioning disk 31 and is fixedly installed with a knob 310. The threaded rod 33 is rotatably connected to the penetration part of the positioning disk 31. The inner wall of the positioning disk 31 is slidably connected to a slider 311. The slider 311 is threadedly connected to the outer wall of the threaded rod 33. By rotating the threaded rod 33 with the knob 310, the slider 311 threadedly connected to it can be driven to slide on the inner wall of the positioning disk 31. The outer wall of the slider 311 is fixedly installed with a limit pin 312. The outer wall of the limit pin 312 fits on the inner wall of the hollow rod 39. When the slider 311 slides, the limit pin 312 will push the hollow rod 39, causing the hollow rod 39 to drive the rotating disk 32 to rotate.

[0025] The above-mentioned auxiliary mechanism 4 includes a connecting rod 41, a pointer 42, and a scale 43. One end of the connecting rod 41 is fixedly installed on the outer wall of the positioning block 34. The other end of the connecting rod 41 penetrates through the positioning disk 31 and is fixedly installed with a pointer 42. The penetration part of the connecting rod 41 and the positioning disk 31 is slidably connected. The outer wall of the positioning disk 31 is fixedly installed with a scale 43. By using the scale 43 in cooperation with the pointer 42, the moving distance of the positioning block 34 can be observed, so that the positioning block 34 can be accurately positioned according to the size of the flange, further facilitating the installation of the roller body 1 by the staff. The outer wall of the pointer 42 fits on the outer wall of the scale 43. When the positioning block 34 slides on the inner wall of the positioning disk 31, it can drive the pointer 42 to fit and move synchronously on the outer wall of the scale 43 in cooperation with the connecting rod 41.

[0026] Working principle: By rotating the screw rod 33 through the knob 310, the slider 311 threadedly connected thereto is driven to slide on the inner wall of the positioning disk 31 and gradually approach the knob 310. At this time, the limit pin 312 on the side wall of the slider 311 will push the hollow rod 39, causing the hollow rod 39 to drive the turntable 32 to rotate. At this time, the turntable 32 will drive the arc plate 37 to rotate synchronously. During the rotation of the arc plate 37, the arc groove 38 will squeeze the L-shaped rod 36, causing the L-shaped rod 36 to push the positioning block 34, so that the positioning block 34 slides on the inner wall of the positioning disk 31 and gradually moves away from the roller shaft 2, thereby the distance between the positioning hole 35 and the roller shaft 2 can be adjusted, and thus the position of the positioning hole 35 can be adjusted according to the position of the flange mounting hole on the machine tool to adapt to the flange on the machine tool, without disassembling and replacing the flange on the machine tool, which is convenient for the staff to install and disassemble the roller body 1. When the positioning hole 35 is aligned with the flange mounting hole on the machine tool, then pass the bolt through the positioning hole 35 and the flange mounting hole, and then tighten the bolt with a nut to complete the installation of the roller body 1.

[0027] While the positioning block 34 slides on the inner wall of the positioning disk 31, it can drive the pointer 42 to fit and move synchronously on the outer wall of the scale 43 in cooperation with the connecting rod 41. At this time, the movement distance of the positioning block 34 can be observed by using the scale 43 in cooperation with the pointer 42, and the distance between the positioning block 34 and the roller shaft 2 can be judged according to the radius of the roller shaft 2, so that the positioning block 34 can be accurately positioned according to the size of the flange, further facilitating the staff to install the roller body 1.

[0028] The above generally describes the present utility model in detail, but based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements without departing from the spirit of the present utility model are within the protection scope of the present utility model.
