Description

Floating grinding machine

Technical Field

The invention relates to the field of processing equipment, in particular to a floating grinding machine.

Background

About 80% of parts in a whole automobile are molded by adopting a high-pressure cast metal method, the die casting process is a process of filling molten alloy liquid into a casting mold through high speed and high pressure, so flash, burrs and the like inevitably occur, and particularly, products with complex structures and more curved surfaces, such as a throttle valve, have more flash in die casting, are different in shape and thickness and difficult to determine the edge, and the effective removal of the flash is a difficult problem in die casting production.

At present, domestic die-casting enterprises begin to adopt a method of 'mechanical arm + polisher' to remove burrs, and the method has the advantages of high burr removing efficiency, low labor intensity of workers and stable product quality. However, since the industrial robot and the polishing motor are rigid bodies and have no deformability, the industrial robot and the polishing motor may be damaged by an irregular burr and an explosive knife during burr removal and polishing operation.

Industrial manipulators cannot avoid rigidity due to the characteristics of the industrial manipulators, so that floating polishing motors are developed in many domestic enterprises, polishing workpieces are flexibly contacted with polishing cutters, and polishing effect is guaranteed. Chinese patent CN103737484A discloses a floating type rotary polishing spindle mechanism and polishing method, comprising a base, a hinged support, a polishing tool, a spindle motor, a spindle support and a floating cylinder assembly, wherein the floating cylinder assembly comprises a cylinder base, a floating cylinder and a Y-shaped joint, and the polishing tool is rotatably connected with the spindle motor. When the flexible contact type polishing machine works, the gas is sealed in the floating cylinder through the electromagnetic valve, the position of a piston of the cylinder can be randomly adjusted through the pneumatic element, when a workpiece contacts with the polishing tool from top to bottom or from bottom to top, the workpiece is supported through the hinged support, and the gas on one side of the piston of the floating cylinder is compressed to generate elastic resistance, so that the flexible contact between the workpiece and the polishing tool can be realized, and the polishing tool is prevented from being damaged; meanwhile, the floating cylinder is adopted for flexible adjustment, so that the motion damping can be increased, the vibration can be reduced, the floating cylinder is suitable for being applied to the field of automatic casting polishing and finishing together with a robot, and the load size and the impact resistance of the robot in work can be accurately controlled. However, the floating type rotary grinding spindle mechanism has the following defects that on one hand, the floating mechanism takes air as a medium, and the sealing performance is required to be high; on the other hand, the motor can generate heat when working, the heat cannot be effectively led out after sealing, the structure is complex, the technical level is high for maintenance, and the cost is correspondingly increased; meanwhile, the elastic resistance of the floating cylinder is used as a floating force source, the floating range of the floating cylinder is not limited, and poor products can flow out.

Therefore, the polisher which is simple in structure, low in cost, free in floating and limited in floating is particularly necessary, and particularly the deburring process in the casting industry is more urgent.

SUMMERY OF THE UTILITY MODEL

The invention aims to provide a floating polisher which is simple in structure, low in cost, good in machining performance, free in floating and capable of solving the problems that an existing floating motor is complex in structure, can float only through external compressed air and is extremely high in purchase cost.

The utility model provides a polisher of floating, construct including support bench, motor, cutter, motor clamping, support bench fixed connection on ground or other fixed places, the cutter dress is on the motor, the polisher of floating still includes free floating mechanism, free floating mechanism fixed connection is in support bench top, motor fixed mounting be in free floating mechanism is last, free floating mechanism can for the product in the processing with the rigid contact between the cutter plays the cushioning effect.

The free floating mechanism comprises an upper top plate, a base plate, floating springs and a lower bottom plate, wherein the upper top plate and the lower bottom plate are provided with grooves which are opposite in pairs, one ends of the floating springs are fixed in the grooves of the upper top plate, the other ends of the floating springs are embedded into the corresponding grooves in the lower bottom plate, and the base plate is arranged on four sides of the upper top plate. In the polishing process, the acting force between the product and the polishing cutter is transferred to the floating spring and generates certain deformation, so that the floating action is generated, and meanwhile, the floating stroke is relatively limited by the gap between the base plate and the lower bottom plate.

Compared with the prior art, the invention has the obvious advantages and beneficial effects that:

the floating grinding machine disclosed by the invention utilizes the compression resistance and shearing resistance of the spring to realize the free floating of the grinding machine by a simple mechanical principle, so that a product is flexibly contacted with a grinding cutter; meanwhile, the clearance between the base plate and the lower base plate is used as a control value, and the floating stroke is controlled quantitatively, so that the polishing consistency of the product is effectively ensured. Compared with various floating polishing devices at home and abroad, the floating polishing device has the advantages of simpler structure, more convenient manufacture, lower cost and wider application range.
