Description

Technical Field

[0001] This utility model relates to the field of roller ring processing technology, specifically to a roller ring grinding processing equipment. Background Technology

[0002] Chinese Patent Application No. 202121989426.6 discloses an integrated machine for grinding and chamfering roller rings, relating to the field of roller ring processing technology. It includes a base, a drive mechanism mounted on the base, a clamping seat connected to the drive mechanism, and a chamfering mechanism mounted on the base. The clamping seat is used to clamp the roller ring and has the freedom of rotation by means of the drive mechanism. It also includes a grinding mechanism mounted on the base. The grinding mechanism includes a first horizontal and vertical moving unit mounted on the base, a drive unit mounted on the first horizontal and vertical moving unit, and a grinding wheel connected to the output end of the drive unit.

[0003] The above-mentioned solution can use a thinner grinding wheel to machine a groove in the middle of the outer circumference of the roll ring, so that it can be used for plastic deformation of round steel on the rolling mill; or a thicker grinding wheel can be used to grind the arc-shaped outer edges at both ends of the axial direction of the roll ring, so that the roll ring in the middle section of the rolling mill can pre-shape or extrude and deform the square steel, thereby facilitating the rolling mill to shape the square steel into round steel.

[0004] When the above method is used for grinding roller rings with arc-shaped outer edges, the machining surface is arc-shaped, the axes of the grinding wheel and the clamped roller ring are parallel (the installation directions of the grinding wheel and the roller ring are the same), the cutting resistance encountered by the grinding wheel when it moves axially is large, and the grinding wheel is prone to tilting (the larger the size of the grinding wheel, the more likely it is to tilt), which can easily lead to damage to the grinding wheel and the roller ring being machined. Utility Model Content

[0005] The purpose of this invention is to provide a roller ring grinding equipment that facilitates grinding the outer arc surface of the roller ring end, ensures the processing effect, and minimizes damage to the grinding wheel and roller ring workpiece.

[0006] To achieve the above objectives, this utility model employs a roller ring grinding processing equipment, including a grinding mechanism and a clamping mechanism for clamping roller ring workpieces. The grinding mechanism includes a grinding wheel and a displacement driver for moving the grinding wheel closer to or away from the roller ring workpiece. The clamping mechanism is characterized by being mounted on a first translation mechanism, moving along a first horizontal direction under the action of the first translation mechanism. The grinding mechanism sits atop the first translation mechanism via a bracket. The axis of the grinding wheel is perpendicular to the first horizontal direction, and the axis of the roller ring workpiece clamped by the clamping mechanism is the same as the first horizontal direction. The bracket includes a fixed bracket and a movable bracket on which the grinding mechanism is fixed. The lower end of the movable bracket is rotatably fixed to the fixed bracket about a rotation axis, which is parallel to the axis of the grinding wheel. The movable bracket is equipped with a rotation driver for rotating the movable bracket about the rotation axis.

[0007] When it is necessary to grind and deburr the outer wall of the end of the roller ring workpiece, first clamp the roller ring workpiece on the clamping mechanism and select the grinding wheel. Then, the roller ring workpiece is rotated by the rotation function of the clamping mechanism, and the grinding wheel is brought closer to the roller ring by the displacement function of the grinding mechanism, thereby achieving contact grinding and deburring. When it is necessary to grind the outer arc surface of the end of the roller ring workpiece, start the rotation driver to make the movable bracket drive the entire grinding mechanism to rotate, thereby achieving arc surface grinding. The relative position between the roller ring workpiece and the grinding wheel can be adjusted through the first translation mechanism, so that it can be used for grinding the plane at the middle of the circumferential outer wall of the roller ring workpiece, and for grinding the plane at different lengths of the middle of the circumferential outer wall of roller ring workpieces with different axial lengths. At the same time, the first translation mechanism and the rotary drive can be used simultaneously to grind the arc surface of roller ring workpieces with different curvatures, thereby improving the applicability of the device of this utility model. It does not require setting up different grinding processing equipment to grind the same roller ring workpiece, and it can also be used for grinding roller ring workpieces with different arc surfaces.

[0008] The grinding wheel of this utility model grinding processing equipment is installed in a different direction than the roller diameter workpiece, and the grinding wheel can rotate. During the processing, the grinding angle can be adjusted as needed to avoid excessive cutting resistance between the grinding wheel and the roller ring workpiece due to improper angle, thereby reducing the tilt and damage of the grinding wheel, extending the service life of the grinding wheel, and protecting the roller ring workpiece from unnecessary damage.

[0009] Preferably, a driven wheel is fixed at the rotation axis of the movable bracket, and a rotation driver is directly or indirectly fixed to the fixed bracket. The output end of the rotation driver is provided with a driving wheel, and the driving wheel is linked to the driven wheel through a first transmission belt or chain. The outer diameter of the driven wheel is larger than the outer diameter of the driving wheel.

[0010] By connecting the driving wheel and the driven wheel with a drive belt or chain, the power of the rotary drive can be transmitted to the movable support, thereby achieving precise rotational control of the movable support. This transmission method ensures smooth and accurate rotation, guaranteeing that the angle adjustment of the grinding wheel meets the processing requirements. Because the outer diameter of the driven wheel is larger than that of the driving wheel, it can reduce speed and increase torque, better overcome resistance, and ensure the smooth progress of the processing.

[0011] This utility model of grinding and processing equipment uses a chain or belt to realize the rotation of the movable support. Compared with other rotation linkage structures, it can buffer and reduce shock, and is better suited for grinding wheels that need to be frequently started and stopped, ensuring the processing effect and avoiding damage to the grinding wheel and roller ring workpiece.

[0012] Preferably, an angle position detector is provided between the rotation axis of the movable support and the fixed support, the angle position detector including a movable part that is linked to the movable support and a plurality of detection parts fixed on the fixed support and arranged in a ring with the rotation axis as the center.

[0013] The angle position detector can monitor the rotation angle of the movable support in real time, that is, the angle of the grinding wheel relative to the roller ring workpiece. It can accurately obtain the angular position information of the grinding wheel, which not only facilitates automation, but also makes it suitable for processing roller ring workpieces with at least two different arc surfaces, and ensures the consistency of grinding and product quality. The angle position detector of this invention can be selected from existing photoelectric sensors or contact sensors.

[0014] Preferably, the first translation mechanism is disposed on the second translation mechanism, and the second translation mechanism is used to move the first translation mechanism along a second horizontal direction, the second horizontal direction being perpendicular to the first horizontal direction.

[0015] By moving the second translation mechanism, the relative position between the clamping mechanism and the grinding mechanism can be further adjusted. This adjustment can be made not only in the first horizontal direction but also in the second horizontal direction perpendicular to the first horizontal direction. This greatly increases the processing range of the equipment, enabling it to meet the processing needs of larger or more complex roller ring workpieces. It also improves the flexibility and adaptability of the equipment, allowing the length of the entire equipment along the first horizontal direction to be set smaller, and the temporary swing space of the movable support to be set smaller.

[0016] Preferably, the first translation mechanism includes a movable platform with a clamping mechanism fixed on it and a fixed platform fixed relative to the fixed bracket. The movable platform is supported on the fixed platform by a slide rail assembly. The fixed platform is provided with a first translation driver. The output end of the first translation driver is provided with a rotating wheel. A transmission belt is sleeved on the rotating wheel. Both ends of the transmission belt are fixed to the movable platform.

[0017] The slide rail assembly provides stable support and guidance for the movable table, ensuring its smooth movement and preventing machining errors caused by swaying or offset. Compared to using an electric lead screw, the conveyor belt enables the movable table to travel a longer distance in the first horizontal direction with less inertia, making it suitable for frequent starts and stops. Furthermore, the conveyor belt exhibits less vibration and noise, and is also more cost-effective than a lead screw structure.

[0018] This invention has the advantages of facilitating the grinding of the outer arc surface at the end of the roller ring, ensuring the processing effect, and minimizing damage to the grinding wheel and roller ring workpiece. Attached Figure Description
