Description

Technical Field

[0001] The invention belongs to the technical field of grinders and relates to a grinder, in particular to a multi-station grinder utilizing a robot for loading. Background Art

[0002] A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinders use a high-speed rotating grinding wheel for grinding. Under a certain pressure, the abrasive grains of the grinding tool cut, scratch and slide on the surface of the workpiece, thereby removing material from the surface of the workpiece to achieve the required dimensional accuracy, surface roughness and shape accuracy.

[0003] Currently, the grinding process of shaft and rod workpieces is carried out by grinders, but the loading of grinders is usually done manually, resulting in low loading efficiency; in addition, when loading, one process is often completed before another is put in for processing, resulting in reduced loading and unloading efficiency. Summary of the invention

[0005] The object of the present invention can be achieved through the following technical scheme: a multi-station grinding machine that uses a robot to load materials, including a bed, a grinding wheel, a cross-moving device that can move crosswise and a mounting slide arranged on the cross-moving device, characterized in that a multi-station turntable is arranged on the mounting slide, and a plurality of clamps for clamping workpieces are arranged on the multi-station turntable. An automatic loading device is arranged outside the bed, and the automatic loading device includes a base and a robot arm arranged on the base, a trolley to be processed and a trolley that has been processed.

[0006] In the above-mentioned multi-station grinder that uses a robot to load materials, a moving mechanism for controlling the grinding wheel to move up and down is arranged on the bed, and a driving motor for driving the chuck is arranged on the multi-station turntable and behind the chuck.

[0007] In the above-mentioned multi-station grinder that utilizes a robot to load materials, the robot arm includes a robot arm body and a clamp, the clamp includes a clamp body, a driving motor, a transmission gear and two clamping jaws, and the two clamping jaws are each provided with a plurality of gap adjustment mechanisms, and an activity space for the gap adjustment mechanism to move is provided in the clamping jaws, the gap adjustment mechanism is composed of an adjustment block and an adjustment spring, the adjustment block is provided with an anti-slip portion, the transmission gear is composed of a main gear and two driven gears, and the motor shaft of the driving motor 2 is connected to the main gear to drive the two clamping jaws to operate through the driven gear.

[0008] In the above-mentioned multi-station grinding machine utilizing a robot for loading, a barrier plate is provided on the multi-station turntable and between two opposite clamping cylinders.

[0009] In the above-mentioned multi-station grinder using a robot to load materials, both the cart to be processed and the processed cart are provided with a transport box, and the transport box is provided with a plurality of mounting seats for placing bar workpieces.

[0010] In the above-mentioned multi-station grinder that utilizes a robot to load materials, a plurality of tensioning devices are arranged in the mounting seat, the tensioning devices are composed of a tensioning block and a tensioning spring, the tensioning block is provided with an inclined portion, and a movable space 2 is opened in the mounting seat for the tensioning device to move.

[0011] In the above-mentioned multi-station grinder that utilizes a robot to load materials, the transport box is provided with a positioning protrusion for limiting and positioning, the mounting seat is provided with a positioning groove that matches the positioning protrusion, and there are 4 tensioning devices, which are distributed in a cross shape in the mounting seat.

[0012] Compared with the prior art, the present invention replaces manual loading and unloading by setting up a multi-station turntable and a plurality of chucks and a set robotic arm. When one chuck is working, the robotic arm can load and unload the chuck that is not being processed, which greatly improves the production efficiency. The gap adjustment mechanism provided on the jaws can clamp bars of different diameters under a certain size and reduce the adjustment of the jaws due to size reasons. The locking device provided on the mounting seat can make the bar vertical, which is more convenient for the clamping of the jaws and reduces the falling due to bumps during transportation.
