Description

Technical Field

[0001] This utility model relates to the field of grinding technology, specifically to a four-axis linkage double-sided grinding machine device. Background Technology

[0002] A four-axis linkage double-sided grinder is a high-precision and high-efficiency CNC grinder. It typically has two pairs of opposing grinding heads for grinding. The two pairs of grinding heads are located at different heights. The grinding heads are driven to rotate by a motor, and the workpiece enters between the two pairs of high-speed rotating grinding heads. The two pairs of grinding heads can simultaneously grind both ends of the workpiece. This design can effectively improve processing efficiency and accuracy, while reducing the possibility of workpiece deformation.

[0003] Some existing four-axis linkage double-sided grinding machines lack a feeding structure and require a special clamping device for feeding. This not only increases the production cost of the grinding machine, but also requires operators to adapt and adjust the clamping device and the grinding machine before it can be used, which raises the barrier to entry. Therefore, a four-axis linkage double-sided grinding machine device is proposed to address the above problems. Utility Model Content

[0025] Workflow: Before use, install the workbench 1 in a suitable position and connect the power supply. This device is equipped with an external controller, which is electrically connected to the first drive motor 23, the second drive motor 32, the multi-stage electric telescopic rod 41, and the third drive motor 53. Manual operation of the external controller allows adjustment of the operating status of the first drive motor 23, the second drive motor 32, the multi-stage electric telescopic rod 41, and the third drive motor 53. All of the above are existing technologies. Before using the device, ensure that the paired first limit frames 34 are at their furthest distance, that the multi-stage electric telescopic rods 41 are fully extended, and that the paired second limit frames 55 are at their furthest distance. When using this device... The operator first places the workpiece to be polished between two pairs of first limiting seats 21. The pair of polishing rollers 24 on the lower side contact the lower side of the workpiece. An external controller then synchronously retracts two multi-stage electric telescopic rods 41, which in turn drive two transmission blocks 42 to move downwards. This causes the first limiting seat 21 and the first motor seat 22 on the upper side to move downwards together, bringing the pair of polishing rollers 24 on the upper side into contact with the upper side of the workpiece. The two pairs of polishing rollers 24, in conjunction with two sets of limiting rollers 25, can limit the workpiece in the vertical direction. Subsequently, the operator can use the external controller to synchronously rotate two pairs of second drive motors 32. The second drive motors 32 can... Rotating the adjusting rod 33, which is limited by the second limiting seat 31, causes the pairs of first limiting frames 34, symmetrically distributed in the front-to-back direction, to move closer together. The pairs of first limiting frames 34 limit the workpiece to be ground in the front-to-back direction. Then, the operator can use an external controller to rotate the two third drive motors 53. The third drive motors 53, fixed by the second motor seat 52, can drive the adjusting shaft 54, limited by the third limiting seat 51, to rotate, causing the second limiting frames 55 to move left and right, bringing the two second limiting frames 55 closer to the workpiece to be ground. The two second limiting frames 55 limit the workpiece in the left-to-right direction. Subsequently, the operator can use an external controller to rotate the two pairs of first drive motors 34. The first drive motor 23 rotates synchronously, causing the two third drive motors 53 to rotate synchronously. The first drive motor 23, which is fixed by the first motor base 22, can drive the grinding roller 24, which is limited by the first limit seat 21, to rotate synchronously. The grinding roller 24 can grind the workpiece to be ground. The two sets of limit rollers 25 can continue to limit the workpiece to be ground in the vertical direction. At the same time, the third drive motor 53, which is fixed by the second motor base 52, can drive the adjusting shaft 54, which is limited by the third limit seat 51, to rotate, causing the two second limit frames 55 to move synchronously in the horizontal direction, so that the workpiece to be ground can move left and right, ensuring that the two pairs of grinding rollers 24 can grind all parts of the workpiece to be ground.This device uses two pairs of adjustable-gap grinding rollers 24 and two sets of adjustable-gap limiting rollers 25 to limit the workpiece in the vertical direction, two pairs of adjustable-gap first limiting frames 34 to limit the workpiece in the front-back direction, and two adjustable-gap second limiting frames 55 to limit the workpiece in the left-right direction. Simultaneously, the two pairs of rotatable grinding rollers 24 grind the workpiece, and the two synchronously movable second limiting frames 55 move the workpiece left and right, allowing for comprehensive grinding. This device integrates a workpiece clamping, positioning, and feeding mechanism, adapting to workpieces of different sizes. It not only saves on grinding machine production costs but also eliminates the need for adaptation and adjustment of the first limiting components 3, the spacing adjustment components 4, the second limiting components 5, and the grinding machine, making it more accessible to users.
