Abstract
The utility model relates to a clamping device for positioning and drilling a tooth frame, which comprises a mounting base, a positioning block, two upper ejector rods and a lower ejector rod, wherein the mounting base has a groove-shaped structure, the two upper ejector rods are perpendicularly arranged on the upward-convex upper surface of the groove of the mounting base, the bottom ends of the both two upper ejector rods pass through the upward-convex lower surface, the positioning block is fixedly arranged on the upward-convex side surface of the groove, a positioning hole is formed on the positioning block, the lower ejector rod is perpendicularly arranged in the middle of the downward-convex lower surface of the groove, the bottom end of the lower ejector rod passes through the downward-convex upper surface, and a pressure plate is arranged at the lower end of the lower ejector rod. A blank is clamped and positioned by the clamping device, and then the tooth frame and the blank are drilled by a drill bit which passes through the positioning hole. The drilling is carried out through the device, so that the position and size of the process hole on the blank are the same as those of the process hole on the tooth frame, so as to provide convenience for the following procedures.
Description
Technical field
The utility model belongs to retainer datum hole manufacture field, especially a kind of retainer location drilling clamping device.
Background technology
The retainer fabrication hole is the positioning reference in all technologies of processing retainer; If adding, the following preface product of technology hole location skew can not carry out man-hour; So require its position degree quite strict, traditional jig processing makes the fabrication hole size offset after the processing influence the machining accuracy of postorder size because of blank shape difference location is inaccurate.
Summary of the invention
The purpose of the utility model is to overcome the prior art deficiency, and a kind of retainer location drilling clamping device simple in structure, reasonable in design, easy to use is provided.
The technical scheme that the utility model adopts is:
A kind of retainer location drilling clamping device is made up of mounting base, locating piece and two upper ejector pins and a lower push rod, and mounting base is the groove type structure; Two upper ejector pins of the vertical installation of this mounting base groove epirelief upper surface; The epirelief lower surface is all passed in two upper ejector pin bottoms, and groove epirelief side surface installs a positioning block, is shaped on a locating hole on this locating piece; This locating hole and mounting base recess are in the same way; The vertical lower push rod of installing in protruding lower surface middle part under the groove, protruding upper surface is passed down in this lower push rod bottom, in this lower push rod bottom one pressing plate is installed.
And said upper ejector pin and lower push rod all can upper and lowerly move.
And in said two upper ejector pins, one is installed in the locating piece top, and another is installed in the epirelief middle part.
Advantage and good effect that the utility model adopts are:
1, the utility model is that blank and retainer are placed the mounting base groove, retainer between blank and locating piece, blank bottom and pressing plate joint; Regulate through lower push rod; Upper ejector pin is regulated in pressing plate and blank displacement thereupon that its bottom is installed simultaneously, when the blank top with after upper ejector pin contacts; Can blank be stepped up the location, retainer and blank holed through locating hole with drill bit again.Through this device boring, make blank consistent, for following process facilitates with the fabrication hole position dimension on the retainer.
2, but the utility model adopts upper ejector pin three-point fix rapid-mounted, avoids blank that crooked phenomenon is arranged in being installed, and uses on the lower side the push rod location can make two location of product stress point holding capacity identical and can firmly lock product, and product stability is strong in the processing.
Description of drawings:
Fig. 1 is the front view of the utility model;
Fig. 2 is the left view of Fig. 1.
The specific embodiment:
Through specific embodiment the utility model is done further to detail below, following examples are descriptive, are not determinate, can not limit the protection domain of the utility model with this.
Like Fig. 1～2, a kind of retainer location drilling clamping device is made up of mounting base 7, locating piece 4 and two upper ejector pins 1 and a lower push rod 6.
The utility model innovative point is:
Mounting base is the groove type structure; Two upper ejector pins of the vertical installation of this mounting base groove epirelief upper surface, the epirelief lower surface is passed in the upper ejector pin bottom, and groove epirelief side surface passes through fixedly a positioning block of rivet 3; Be shaped on locating hole 2 on the locating piece; Lower push rod is installed at protruding lower surface middle part under the groove, and protruding upper surface is passed down in the lower push rod bottom, in this lower push rod bottom one pressing plate 5 is installed.
In the present embodiment, said upper ejector pin and lower push rod all can upper and lower mobile adjustings.
In the present embodiment, said two upper ejector pins, one of them is installed in the locating piece top, and another is installed in the epirelief middle part.
The utility model method for using is:
Blank and retainer are placed the mounting base groove, retainer between blank and locating piece, blank bottom and pressing plate joint; Regulate through lower push rod; Upper ejector pin is regulated in pressing plate and blank displacement thereupon that its bottom is installed simultaneously, when the blank top with after upper ejector pin contacts; Can blank be stepped up the location, retainer and blank holed through locating hole with drill bit again.Through this device boring, make blank consistent, for following process facilitates with the fabrication hole position dimension on the retainer.
