Abstract
The invention relates to a high-precision positioning fixture, which comprises a horizontal base plate, wherein an upright plate is arranged on the base plate; the upper part of the upright plate is provided with a pressing plate through a mounting base; a pressing block is hinged in the center of the pressing plate; and a horizontal positioning bolt is arranged on the mounting base between the pressing plate and the upright plate. The high-precision positioning fixture is conveniently used, is strong in practicability, can be used for achieving a high-precision positioning clamping effect and increasing the production efficiency, and is suitable for workpieces in various complex shapes.
Description
Technical field
The present invention relates to positioning equipment, especially a kind of high-precision fixed position fixture that is fit to complex-shaped product orientation use.
Background technology
In machining industry, run into irregular black skin positioning phenomenon through regular meeting and occur, because its shape more complicated adding the easy inaccurate phenomenon in location that occurs in man-hour, causes processing precision of products low.In addition, during traditional manufacturing complex shapes product, anchor clamps need frequent the replacing, make complicatedly, and Practical Performance is low, and frequently change anchor clamps and also prolonged the production time, have reduced production efficiency.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of novel clamp easy to use is provided, these anchor clamps can accurately be located the complicated shape product, can guarantee product quality, improve working (machining) efficiency.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of high-precision fixed position fixture, the base plate that comprises a level is installed a vertical riser on this base plate, it is characterized in that: a pressing plate is installed by mount pad in the top of riser, the center hinge of this pressing plate is adorned a briquetting, installs the dog screw of a level on the mount pad between pressing plate and the riser.
And described pressing plate is parallel to the riser setting, and the end hinge of pressing plate is contained on the mount pad, and the other end is contained on the riser by the holding screw top.
And an installing hole is made at described pressing plate center, and briquetting is installed in this installing hole by vertical bearing pin.
Advantage of the present invention and beneficial effect are:
1, two location benchmark are installed on this positioning fixture, dog screw can position in X-axis and hold out against, and briquetting can position the workpiece sidewall and compress, and briquetting is that face contact with workpiece, so has guaranteed the accuracy and the fastness of locating.
2, this positioning fixture is because can clamping is on frock more accurately with the workpiece locating surface, so the workpiece stress surface is even, the impetus equilibrium, and the firm non-loosening phenomenon of work in-process has guaranteed that the crudy of workpiece is good, the precision height.
3, dog screw of this positioning fixture and briquetting all have certain amount of movement, therefore use these anchor clamps to position multiple complex part, have save the trouble of frequent replacing anchor clamps, have shortened process time, have improved working (machining) efficiency.
4, the present invention is easy to use saves trouble, practical, can realize that high-precision location clamps effect, enhances productivity, and is applicable to that the workpiece of different shape complexity uses.
Description of drawings
Fig. 1 is a front view of the present invention;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
The invention will be further described below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of high-precision fixed position fixture comprises the base plate 1 of a level, and this plate upper surface is installed a vertical riser 2.Innovative point of the present invention is: a pressing plate 4 is installed on the top of riser, and an end of pressing plate is contained on the mount pad 7 by pivot pin 8 hinges, and the other end is contained on another mount pad of riser by holding screw 3 tops.This pressing plate is parallel to the riser setting, but forms the gap of a place work piece between itself and the riser.An installing hole is made at the center of this pressing plate, and hinge is adorned a briquetting 5 in this installing hole, and this briquetting is that bearing pin 6 hinges by vertical setting are contained in the pressing plate, and briquetting can horizontally rotate around bearing pin.Install the dog screw 9 of a level on the mount pad between pressing plate and the riser, this dog screw can move horizontally along X-axis.
Operation principle of the present invention:
Workpiece is placed on the base plate, and the running fix screw carries out the X-axis location to workpiece, and then rotates briquetting, and its inwall and surface of the work are fitted, and realizes that the location clamps.
