Abstract
The utility model relates to a location device, comprising a body, a connecting rod mechanism, and two location sliding pins, wherein two location sliding pins are driven by the connecting rod mechanism for relatively sliding inside the body, an end of two location sliding pins is extendable to the outside of the body and are connected with the work piece, the connecting rod mechanism and a driving rod which is connected with a pushing rod of a cylinder are rotatablely connected with two symmetrical connecting rods, and two symmetrical swing arms are separately connected with two symmetrical connecting rods. The swing arms of the connecting rod mechanism could extend through the holes which are arranged on the bottom of the body and reaches the concave portion of two location sliding pins, which could drive the location sliding pin relatively slide inside the body. The utility model is characterized in that when the work piece is clamped slightly, the location sliding pin is driven by the connecting rod mechanism for extending to the outside of the body and entering to a base hole of the work piece assembly, which accomplishes the work piece location. After the work piece is processed, the swing arms which are driven by the cylinder for swinging drives the location sliding pin for drawing back to the inside of the body.
Description
[technical field]
The utility model relates to a kind of positioner, particularly a kind of positioner that workpiece accuracy is had relatively high expectations.
[background technology]
Traditional locate mode is to adopt stationary positioned type piece and alignment pin to be used in combination, and makes the workpiece location, as shown in Figure 1, uses alignment pin 10 that workpiece 11 is fixed on the location type piece 12.Such locate mode so just causes the positioning accuracy of workpiece low because workpiece and location type piece have certain clearance, and the combined workpiece of multinomial position accuracy demand is especially arranged, and the positional precision of workpiece is difficult to guarantee especially.
[utility model content]
The purpose of this utility model is to provide a kind of positioner, can accurately guarantee the installation positioning accuracy of workpiece.
The utility model provides a kind of positioner, comprise body, linkage, two location sliding pins, described two location sliding pins can be in the coaxial relative slip of body interior under the effect of linkage, an end of described two the location sliding pins extended body outside and with workpiece to be installed clamping mutually.
Flexibly connect the connecting rod of two symmetries on described linkage and the drive rod that cylinder push-rod links to each other, the connecting rod of described two symmetries flexibly connects the swing arm of two symmetries respectively.
The swing arm of described linkage can be passed the recesses of hole below the body and two location sliding pins to replacing, and can drive the relative motion in body of location sliding pin, when clamping, linkage drives the location sliding pin and stretches out body exterior, and enter in the reference for installation hole of workpiece, with the workpiece location, after machining, cylinder rod drives the swing arm swing, and swing arm drives in the location sliding pin withdrawal body.
Described two location sliding pins are linked to each other by the compression spring, can drive the location sliding pin after machining and get back in the body.
The utility model positioner adopts cylinder drivening rod oscillating arm mechanisms to drive the translation of locating sliding pin, and realizes the installation location of workpiece.The utility model positioner can be processed the higher workpiece of required precision the location is installed, and it is simple in structure, and reliable operation adopts compressed air as power source, the production efficiency height, and can adopt the combination of a plurality of mechanisms to solve the requirement that a plurality of position dimensions are arranged.

[specific embodiment]
Specify embodiment of the present utility model below.Fig. 2 is the non-clamping work pieces status architecture of a utility model schematic diagram.Described positioner comprises body 6, linkage, two location sliding pins 5, as shown in Figure 4, described two location sliding pins 5 comprise the recess 18 that can replace mutually with the swing arm 3 of linkage, can be at the slide-and-guide cylinder 17 of body interior slip, the hole that the body both ends of the surface can be passed in the face of cylinder 16 reaches the body outside, not-go-end end face 15 can be replaced mutually with workpiece, and positioning cylindrical surface 14 can pass the workpiece datum hole workpiece is fixed, and described two geocoded activity pins 5 link together by compression spring 7.Described linkage comprises cylinder push-rod 13, with the connecting rod 8 that flexibly connects two symmetries on the drive rod that described cylinder push-rod 13 links to each other, the connecting rod 8 of described two symmetries is flexibly connected the swing arm 3 of two symmetries respectively by the flexible connection pivot pin, 2 is fixedly connected pivot pin, when the piston push rod 13 of cylinder 9 stretched out, connecting rod 8 can drive swing arm 3 swings.As shown in Figure 5 and Figure 6, described body 6 two ends comprise detachable end 4, and described end cap 4 is connected on the body 6 by bolt, and the swing arm 3 of linkage can be passed the hole of body 6 bottom surfaces and be replaced mutually with the geocoded activity pin.
The course of work of the present utility model is for to be placed on workpiece 11 on the positioner, and when cylinder 9 piston push rods 13 stretched out, connecting rod 8 drove swing arms 3 swings, and swing arm 3 is stirred slide jaw 5 slippages and stretched out positioner body 6 and make workpiece 11 location, as shown in Figure 3.Slip location axle pin 5 Thrust Faces 15 are withstood workpiece 11U profile inboard, guarantee the distance (when a plurality of relative dimensions was arranged, this positioner especially can guarantee the relative dimensions of U profile and all the other structural members) of workpiece two U profiles.Extending area positioning cylindrical surface 14 stretches in the coaxial circular hole of U type spare both sides, determining the position and the axiality in two holes, thereby has determined the tram of workpiece.After the machining of workpiece, cylinder 9 drives cylinder push-rods 13 withdrawals, and connecting rod 8 drives swing arms 3 swings, slide jaw 5 is withdrawn under the drive of swing arm 3 and return spring 7 in the body 6, simultaneously, its institute's spring also can drive positioner and unclamp workpiece, finishes a working cycles.
