Description

Technical Field

[0001] This utility model relates to the field of pressure roller shaft processing technology, and specifically to a pressure roller shaft processing fixture. Background Technology

[0002] The pressure roller shaft is a key component of a calender, responsible for transmitting power and withstanding significant torque and extrusion pressure. Its design and material selection directly affect the operational stability of the equipment and product quality. It is widely used in calenders in industries such as papermaking, plastic film, and metal sheet manufacturing. During the manufacturing process of the pressure roller shaft, it is often necessary to use clamps to fix it in place to ensure stability during processing.

[0003] Currently, when processing the pressure roller shaft, it is mostly held at both ends of the outer wall of the pressure roller shaft by two sets of symmetrical clamps. However, the existing processing methods mostly involve drilling or grinding the two ends of the pressure roller shaft. When fixing it, it is necessary to adjust the position of the clamps on both sides to prevent affecting the processing of the shaft ends. Furthermore, when processing the bottom and side walls, it is necessary to disassemble and reassemble the fixtures to adjust the position of the pressure roller shaft wall, resulting in poor performance. Utility Model Content

[0004] The purpose of this utility model is to provide a pressure roller shaft processing fixture. By setting up a support ring, a movable ring, a retaining ring, and a positioning mechanism, after the pressure roller shaft passes between the support ring and the side retaining ring, the four clamping plates on the same side retaining ring can close and clamp the outer wall of the pressure roller shaft. Under the combined action of the two sets of clamping plates in front and behind the support ring, the pressure roller shaft can be quickly and effectively centered, resulting in better performance and solving the above-mentioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure roller shaft processing fixture, comprising:

[0006] The base has a support frame on its top side, a support ring fixed at the top of the support frame, and movable rings rotatably mounted on both sides of the support ring. A side stop ring is fixed to the outer side of the movable ring, and a sliding component is provided between the movable ring and the support ring. The base is provided with a driving mechanism, which is used to drive the two movable rings to rotate synchronously.

[0007] The positioning mechanism includes sliding cavities arranged in a ring array at four ends outside the side retaining ring. A slider is slidably connected inside the sliding cavity. One end of the slider extends outside the sliding cavity and is fixed with a connecting frame. A clamp is connected to one end of the connecting frame relative to the slider. A moving component is provided inside the sliding cavity, and the slider is driven to move by the moving component.

[0008] Preferably, the driving mechanism includes a fixed frame fixedly connected to the top side of the base. A toothed roller is rotatably connected to the inner side of the fixed frame via a rotating shaft. A first motor is fixed to one end of the fixed frame. The output end of the first motor is connected to the toothed roller. A connecting shaft is rotatably connected to the bottom end of the support frame near the top of the toothed roller via a bearing. Gears that mesh with the toothed roller are symmetrically fixed at both ends of the connecting shaft. Toothed rings are fixed to the outer sides of the two movable rings, and the two toothed rings mesh with the two gears respectively.

[0009] Preferably, the sliding component includes a plurality of T-shaped locking blocks disposed on the inner side of the movable ring, and both sides of the support ring are provided with T-shaped sliding grooves that match the T-shaped locking blocks.

[0010] Preferably, the moving component includes a threaded rod rotatably connected inside the slide cavity via a bearing, the slider being threadedly connected to the outside of the threaded rod, and one end of the threaded rod extending to the outside of the side retaining ring and being fixedly connected to a second motor.

[0011] Preferably, a rubber pad is provided on the inner side of the clamping plate.

[0012] Preferably, the base has fixing holes at all four ends.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] By setting up structures such as support rings, movable rings, retaining rings and positioning mechanisms, after the pressure roller shaft passes between the support ring and the side retaining ring, the four clamping plates on the same side retaining ring can close and clamp onto the outer wall of the pressure roller shaft. Under the combined action of the two sets of clamping plates in front and behind the support ring, the pressure roller shaft can be quickly and effectively centered, resulting in good performance.

[0015] By rotating the movable rings onto the support rings, and with the cooperation of the sliding components and the drive mechanism, the two movable rings can drive the two side retaining rings to rotate synchronously on the support rings. This allows the two side retaining rings to drive the pressure roller shaft to rotate slowly through the positioning mechanism, thereby enabling the angle of the pressure roller shaft to be quickly adjusted as needed. This eliminates the need for repeated disassembly and assembly, making the operation convenient and efficient, and greatly improving processing efficiency. Attached Figure Description

[0030] In use, the pressure roller shaft can be passed between the support ring 3 and the side retaining ring 5. By activating the moving assembly, the second motor 19 on the moving assembly can drive the threaded rod 18 to rotate, so that the threaded rod 18 drives the slider 15 to slide in the sliding cavity 14. Then the slider 15 can drive the connecting frame 16 to move, so that the connecting frame 16 drives the clamping plate 17 to approach the pressure roller shaft, so that the four clamping plates 17 on the same side retaining ring 5 close and clamp the outer wall of the pressure roller shaft.
