The specific embodiment
In order to make those skilled in the art better understand the technical solution of the utility model, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Please referring to Fig. 2, Fig. 2 is the structural representation of a kind of specific embodiment of workpiece clamp clamping and positioning device provided by the utility model.
As shown in Figure 2, the upper surface of the bottom surface of workpiece 1 and clamp body 6 is fitted, and the upper surface of workpiece 1 is a machined surface, and promptly the upper surface to workpiece 1 carries out Milling Process, and the upper surface of clamp body 6 forms locating surface, is used at vertical direction workpiece 1 being positioned; Workpiece clamp clamping and positioning device provided by the utility model comprises the compact heap of being located at workpiece 1 side, the contact-making surface of this compact heap and workpiece 1 is the inclined-plane, this inclined-plane tilts to workpiece 1 direction, and under the effect of force application mechanism, the contact-making surface of compact heap and workpiece 1 is adjacent to described workpiece 1.
The workpiece clamp clamping and positioning device of this structure, the contact-making surface of compact heap and workpiece 1 is the inclined-plane, when compact heap is applied the clamping force of horizontal direction, compact heap to the active force of workpiece 1 perpendicular to described contact-making surface, because contact-making surface is the inclined-plane, compact heap will have the component of horizontal direction and the component of vertical direction to the active force of workpiece 1, the component of horizontal direction clamps workpiece in the horizontal direction, the component of vertical direction compresses workpiece 1 and locating surface at vertical direction, make and be difficult for producing the gap, location between workpiece 1 and the locating surface, in carrying out Milling Processes, the gauge of workpiece 1 and the depth of parallelism will be guaranteed.
In the preferred version, described compact heap comprises first compact heap 21, second compact heap 22 of being located at workpiece 1 both sides respectively, and this scheme can be carried out clamping and positioning to workpiece 1 simultaneously from workpiece 1 both sides both direction.
In the concrete scheme, force application mechanism specifically can comprise double threaded screw 5, first fairlead 31, second fairlead 32; Clamp body 6 is provided with the axis hole that runs through clamp body 6, first fairlead 31, second fairlead 32 are placed in respectively in the two ends of axis hole of clamp body 6, and first fairlead 31, second fairlead 32 all form key with axis hole by key 4 and are connected, first compact heap 21, second compact heap 22 are fixed with first fairlead 31, second fairlead 32 respectively, and double threaded screw 5 all forms and is threaded with first fairlead 31, second fairlead 32.
The screw thread of one end of double threaded screw 5 is a plus thread, and the screw thread of the other end is a left-hand thread; First compact heap 21 and first fairlead 31 are fixing, the two is an integral body, between first fairlead 31 and the double threaded screw 5 for being threaded, when rotating double threaded screw 5, because first fairlead 31 is that key is connected with the axis hole of clamp body 6, first fairlead 31 can not be with double threaded screw 5 rotations, therefore, between first fairlead 31 and the double threaded screw 5 can relative motion appear because of screw thread thrust, because this structure is a symmetrical structure, the two ends screw thread of double threaded screw 5 is respectively plus thread, left-hand thread, first fairlead 31, second fairlead 32 will be to the third side to moving under the effect of screw thread thrust, under the situation that keyway length on the axis hole of clamp body 6 allows, first fairlead 31, second fairlead, 32 meeting persistent movements are until first compact heap 21, second compact heap 22 compresses workpiece 1.
Because first compact heap 21, second compact heap 22 is the inclined-plane with the contact-making surface of workpiece 1, to first compact heap 21, when second compact heap 22 applies the clamping force of horizontal direction, first compact heap 21, the active force of 22 pairs of workpiece 1 of second compact heap is perpendicular to described contact-making surface, because contact-making surface is the inclined-plane, first compact heap 21, the active force of 22 pairs of workpiece 1 of second compact heap will have the component of horizontal direction and the component of vertical direction, the component of horizontal direction clamps workpiece in the horizontal direction, the component of vertical direction compresses workpiece 1 and locating surface at vertical direction, make and be difficult for producing the gap, location between workpiece 1 and the locating surface, in carrying out Milling Processes, the gauge of workpiece 1 and the depth of parallelism will be guaranteed.
In this scheme, during keyway length long enough on axis hole, because first fairlead 31, second fairlead 32 is an axle with axis hole, the hole cooperates, therefore, whole by first compact heap 21, second compact heap 22, first fairlead 31, second fairlead 32, key 4, the integral body that double threaded screw 5 is formed can be slided at left and right directions, in clamping process, this integral body can be because the position of oneself be adjusted in the position of workpiece 1, thereby avoid workpiece 1 occurrence positions in clamping process to change, so this workpiece clamp clamping and positioning device is when carrying out clamping and positioning to workpiece 1, can not influence the position positioning accuracy of workpiece 1, after Milling Process is finished, can also continue other manufacturing procedures.
In the preferred version, described compact heap and described fairlead are fixed, and are specifically as follows, and described compact heap is provided with installing hole, described compact heap and described fairlead socket, and the outside projection of described fairlead is against the outside of described compact heap.Equally, first compact heap 21 and first fairlead 31, second compact heap 22 and second fairlead 32 all can adopt aforesaid way to fix.
In the foregoing description; the form that double threaded screw 5 is set in clamp body 6 is to first compact heap 21 that is arranged on workpiece 1 both sides, the thrust that second compact heap 22 applies horizontal direction; the utility model is not limited thereto; a single-head screw can also respectively be set in the axis hole of clamp body 6 both sides respectively; two screw rods respectively be placed in the both sides axis hole in first fairlead 31, second fairlead 32 form and be threaded; can carry out clamping and positioning from both direction to workpiece 1 separately respectively, this scheme also should be in protection domain of the present utility model.
Among the above embodiment; from workpiece both sides both direction workpiece is applied clamping force respectively; the utility model is not limited thereto; also a side of workpiece can be fixed; opposite side at workpiece is provided with a compact heap; correspondingly; can be provided with axis hole in the clamp body respective side; in this axis hole, be with the fairlead of fixedlying connected with compact heap; the screw rod that is threaded with fairlead is set in fairlead; fairlead is connected by key with axis hole, only from a direction workpiece is applied clamping force, and this scheme also should be in protection domain of the present utility model.
Among the above embodiment, compact heap and fairlead are fixedlyed connected by socket, spacing mode, and the utility model does not limit the connected mode of compact heap and fairlead, and the two also can be fixedly connected by modes such as welding.
