Description
Technical Field
The invention relates to the field of auxiliary tools, in particular to a clamping tool for flat plate parts.
Background
When the end face of the flat plate part is machined in the machining process, the common method is to press the end face of the flat plate part by using auxiliary tools such as a pressing plate and the like so as to position the flat plate part, and then the end face of the flat plate part is machined; according to the method for positioning the flat plate type part, the end face of the flat plate type part is required to be pressed, so that when the whole end face of the flat plate type part is required to be processed, the pressing plate is required to be loosened, the position of the pressing plate on the end face of the flat plate type part is changed, the pressing plate is pressed again to continue processing, namely, in the processing process of the same end face on the flat plate type part, the flat plate type part is required to be clamped and aligned for many times, and in addition, the precision such as flatness, roughness and the like of the processed end face is influenced by the need of re-tool alignment after each alignment, and the processing quality is reduced;
if the auxiliary tool for pressing the flat plate parts downwards is not used, such as a pressing plate and the like, is in contact with the end surfaces of the flat plate parts, and is changed into a tool for pressing the flat plate parts from the side surfaces by using a pressing block and the like, and the flat plate parts are pressed from the side surfaces, because the flat plate parts are only pressed from the side surfaces and lack downward acting force, in the process of processing the end surfaces, the flat plate parts are easy to tilt at one side due to the cutting acting force of a cutter, so that the flat plate parts cannot be positioned, and the processing cannot be performed;
in order to overcome the problems, an electromagnetic chuck can be used, the electromagnetic chuck is pressed downwards to be positioned, then a flat plate part is placed on the electromagnetic chuck, and the flat plate part is sucked downwards under the electromagnetic action of the electromagnetic chuck, so that the cutting action of a cutter can be overcome, and the whole end face of the flat plate part is machined in one clamping process; however, the area of the electromagnetic chuck is limited, the electromagnetic chuck cannot be suitable for flat plate parts with various sizes and shapes, the adsorption effect of the electromagnetic chuck is limited by materials used for the flat plate parts, and the electromagnetic chuck is difficult to popularize and apply in the actual processing of the flat plate parts due to the fact that the electromagnetic chuck is expensive to operate and inconvenient.

defining the intersection line of the guide inclined plane and any vertical reference plane vertical to the left-right rotation bolt as a vertical base line of the guide inclined plane, wherein all the vertical base lines are obliquely arranged with the vertical direction, so that the pushing block can move obliquely downwards along the guide inclined plane when approaching to the flat plate type part along the direction vertical to the left-right rotation bolt by sliding along the guide inclined plane;
the inclination direction of the kidney-shaped through hole is matched with the inclination movement direction of the jacking block, so that the left-right rotation bolt can move along with the inclination of the jacking block, the jacking block can be close to the flat plate part along the direction perpendicular to the left-right rotation bolt and inclined downwards, and one side of the flat plate part is obliquely jacked downwards.
Preferably, two sections of sliding inclined planes are arranged on the two jacking blocks, and the two sections of sliding inclined planes on the same jacking block are respectively positioned on two sides of the left-handed bolt and the right-handed bolt.
Preferably, one end of the fixing block, which is close to the flat plate part, comprises a section of protruding part, the width of the protruding part is smaller than that of one end of the fixing block, which is far away from the flat plate part, the kidney-shaped through hole is formed in the protruding part, and the two tightening blocks are respectively located on two sides of the protruding part.
Preferably, the fixing block is provided with a plurality of fixing holes for penetrating the fasteners to limit the displacement of the fixing block.
According to the technical scheme, the invention has the beneficial effects that:
according to the clamping tool for the flat plate parts, when the clamping tool is used, the plurality of tools can be respectively fixed on different sides of the flat plate parts, the two jacking blocks can move reversely along the axial direction of the left-right screw bolt and slide along the guide inclined plane through rotating the left-right screw bolt, when the two jacking blocks are mutually close to each other, the two jacking blocks can move along the inclined downward direction and approach the flat plate parts through the arrangement of the inclined directions of the guide inclined plane and the sliding inclined plane, and meanwhile, the left-right screw bolt slides in the kidney-shaped through hole, so that the two jacking blocks are in contact with the side surfaces of the flat plate parts, one side of the flat plate parts is obliquely propped downwards, and all the side surfaces of the flat plate parts are clamped together and propped through the cooperation of the plurality of tools, so that the positioning of the flat plate parts can be realized; compared with the prior art, the pressing plate or the pressing block is used, because the flat plate part is pressed downwards obliquely from the side surface, the condition that the end surface machining is affected due to the fact that the tool fixture contacts with the end surface of the flat plate part does not occur, so that multiple clamping alignment and tool setting are needed in the end surface machining is caused, and the tendency of the upward tilting of the flat plate part caused by the cutting force of the tool is eliminated through the oblique downward acting force of the side surface of the flat plate part, so that the flat plate part can smoothly finish the whole end surface machining through one-time clamping, the flatness, roughness and other precision of the end surface are improved, and the machining quality is ensured; compared with the electromagnetic chuck with small application range and complex structure and high price, the invention is not only suitable for flat plate parts with various sizes and various materials, but also has simple structure, convenient manufacture and transportation and far lower cost than the electromagnetic chuck, and the electromagnetic chuck is only required to be fixed on the side surface of the flat plate part and then rotate left and right screw bolts when in use, has simple and convenient operation, overcomes various defects of the electromagnetic chuck in actual use, and is suitable for popularization and application.
