Abstract
The invention discloses a clamping method for preventing a workpiece from sliding. The method comprises the following steps that an upper clamping arm (1), a connecting arm (2) and a lower clamping arm (3) are connected successively; the clamping surface of the upper clamping arm (1) is parallel to the clamping surface of the lower clamping arm (3); the connecting arm (2) is perpendicular to the clamping surface of the upper clamping arm (1); a screw hole is formed in the end, far away from the connecting arm (2), of the lower clamping arm (3); an inner screw thread is arranged inside the screw hole; a screw (4) is arranged in the screw hole and an outer screw thread of the surface of the screw (4) is matched with the inner screw thread of the screw hole; a clamping board (8) is arranged on the top of the screw (4) and the upper surface of the clamping board (8) is parallel to the clamping surface of the upper clamping arm(1). Through the rotating of the screw in the screw hole, the distance between the top of the screw and the upper clamping arm can be changed, therefore the clamping force between the top of the screw and the upper clamping arm can be adjusted; namely, fast replacement of different-sized baffle bars is convenient, the volume of the baffle bar is small and the operation is easy.
Description
Technical field
The present invention relates to a kind of wood working tool, specifically refers to a kind of clamping means for preventing workpiece from sliding.
Background technology
The gradually mechanization of China's timber processing industry starts from the late Qing Dynasty.At this moment foreign trader sets up mechanization sawmill in China, develops then the wood-working factory with building construction as object such as floor, door and window；20 beginnings of the century set up factories production glued board again.From the mid-50, plywood production has development, then and starts to manufacture particieboard and fiberboard；Surface decoration material and laminated timber etc. also occur successively.This indicates that the wood-processing industry of China has been enter into the modernization period centered on comprehensive utilization.In modern timber processing industry, particularly woodwork industry, surfacer is conventional electric power tool.Generally, surfacer is needed to install shuttle plate on the platform of surfacer, is limited the width of timber by shuttle plate, to process when cutting operation is carried out.But, if if the width change of wood workpiece is frequent, need Jing often to change different shuttle plates, therefore, the supporting amount of its shuttle plate is big, and changes trouble.
The content of the invention
It is an object of the invention to provide a kind of clamping means for preventing workpiece from sliding, in facilitating timber process, blend stop are fixed on the platform of surfacer, it is quick to determine the distance between blend stop and saw blade, the i.e. width of the workpiece.
The purpose of the present invention is achieved through the following technical solutions：
A kind of clamping means for preventing workpiece from sliding, including the upper clip arm, linking arm and lower clip arm that are sequentially connected, the clamping face of upper clip arm is parallel to each other with the clamping face of lower clip arm, linking arm is vertical with the clamping face of upper clip arm, one end of linking arm is provided with screw in the lower clip arm, internal thread is provided with the screw, screw rod is installed in the screw, the external screw thread of screw surface is matched with the internal thread of screw, grip block is provided with the top of screw rod, and the upper surface of the grip block is parallel with the clamping face of upper clip arm.By the upper clip arm being sequentially connected、Linking arm、And lower clip arm，Constitute the framework of " C " font，Screw is set on lower clip arm，Matched screw rod is installed in screw，By the rotation of screw rod，Axially-movable of the screw rod along screw，The distance between the grip block of screw tip and upper clip arm are changed by rotary screw，During use，Blend stop is prevented putting on the platform of surfacer，It is allowed to be adjacent to the fixed blend stop of surfacer，It is placed on blend stop with the upper clip arm end of clamping device，And make lower clip arm be located at the underface of upper clip arm，And under the platform of surfacer，Rotary screw，Reduce the distance between the grip block of screw tip and the clamping face of upper clip arm，So just blend stop can be fixed on platform，It is fixed between screw tip and upper clip arm，Simultaneously by the frictional force that increased between screw tip and planing wood machine platform lower surface of setting grip block，Avoid movement of the screw rod relative to planing wood machine platform，It is more safe and reliable.
The lower end of the screw rod is provided with the through hole along screw rod radial direction, torque arm is set with the through hole, the diameter of the torque arm is less than the aperture of through hole.Further, for the ease of the rotation of screw rod, the bottom of screw rod is provided with through hole, the through hole along screw rod diametric(al) and run through screw rod, be set with torque arm in through hole, by increase rotate screw rod the arm of force, reached reduce twisting resistance purpose.
It is provided with the two ends of the torque arm and blocks, the aperture with diameter greater than through hole blocked.Further, blocking with diameter greater than through-hole diameter can be provided with the two ends of torque arm in the through hole slidably to ensure torque arm, thus, torque arm can in through hole along through hole slidably, while and can be unlikely to depart from through hole under the restriction effect blocked.
Described upper clip arm has reinforcement connect band with the connecting portion and linking arm of linking arm with the connecting portion of lower clip arm.When blend stop is clamped, in order to increase the chucking power between upper clip arm and screw tip, overcome upper clip arm, lower clip arm because of the deformation produced by external force, the connecting portion of linking arm is provided with reinforcement connect band in upper clip arm with the connecting portion and lower clip arm of linking arm.
The present invention compared with prior art, has the following advantages and advantages：
A kind of clamping means for preventing workpiece from sliding of 1 present invention, rotation by screw rod in screw, the distance between screw tip and upper clip arm can be changed, such that it is able to the chucking power at the top of adjusting screw rod and upper clip arm between, facilitate the blend stop quick-replaceable of different size, it is again safe and reliable, meanwhile, it is its small volume, simple to operate；
A kind of clamping means for preventing workpiece from sliding of 2 present invention, the bottom of screw rod is provided with through hole, the through hole along screw rod diametric(al) and run through screw rod, torque arm is set with through hole, by increasing the arm of force for rotating screw rod, the purpose for reducing twisting resistance has been reached, blocking with diameter greater than through-hole diameter is provided with the two ends of torque arm, thus, torque arm can in through hole along through hole slidably, while and can be unlikely under the restriction effect blocked depart from through hole；
A kind of clamping means for preventing workpiece from sliding of 3 present invention, there is reinforcement connect band with the connecting portion and linking arm of linking arm with the connecting portion of lower clip arm in upper clip arm, when blend stop is clamped, the chucking power between upper clip arm and screw tip is increased, and upper clip arm, lower clip arm is overcome because of the deformation produced by external force.
