The purpose of this utility model is to overcome the deficiencies of the prior art and provide a three-axis double-sided processing fixture. On the basis of the traditional fixture, the device increases the rotation function of the fixture so that the workpiece can be rotated 180 degrees for fast conversion of the front and back sides. And then processed.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a three-axis double-sided processing fixture, including a reference vertical plate and a support column installed on the reference vertical plate, the support column is connected to the pressure plate, and the pressure plate is provided with a pressure plate for fixing the workpiece. Tighten the nails, the support column is also connected with a piston plate in contact with the arc surface of the workpiece, a rotating seat is installed on the reference vertical plate, the rotating seat is connected to the reference column through the rotating shaft, and the reference column is fixed on the base plate; the reference column Bolts are arranged on the top, and the bolts penetrate the reference vertical plate at the same time.

Further, pins are provided on the above-mentioned reference column, and the pins pass through the reference column.

Further, baffles are provided at both ends of the above-mentioned rotating shaft.

Further, the above-mentioned reference column is located on the centerline of the base plate.

Further, the number of the above-mentioned reference columns is three.

Further, a suspension ring is installed on each of the four corners of the above-mentioned substrate.

Compared with the prior art, the beneficial effect of the utility model is that the device can turn over the fixture installation plate by 180 degrees by improving the clamping method of the fixture, especially the design of the fixture installation plate, and increasing the rotation seat and the rotation shaft to cooperate. The front and back sides of the workpiece can be converted quickly, thereby realizing fast processing.

Detailed ways

The following will be described in detail with reference to the accompanying drawings in conjunction with the embodiments, so as to further explain the technical features and advantages of the present utility model.

As shown in Figures 1-6, the three-axis double-sided processing fixture of the present invention includes a reference vertical plate 2 and a support column 7 installed on the reference vertical plate 2. The support column 7 is a column or a square column, and the support column 7 is connected Pressing plate 8, the pressing plate 8 is provided with the pressing nail 12 that is used to fix the workpiece 11, and the piston plate 13 that is also connected with the arc surface of the workpiece 11 is connected on the support column 7, and the gap between the piston plate 13 and the workpiece 11 is adjusted by moving back and forth. A swivel seat 4 is installed on the reference vertical plate 2, and the swivel seat 4 is connected to the reference column 3 through the rotary shaft 5, and the reference column 3 is fixed on the base plate 1; the reference column 3 is provided with a bolt 10, and the bolt 10 penetrates the reference column at the same time. The vertical plate 2 is used to limit and stop the rotation of the reference vertical plate 2, so as to improve the machining accuracy.

Further, the reference column 3 is provided with a pin 9, the pin 9 runs through the reference column 3, and the material of the pin 9 is a soft material, such as aluminum or copper, to prevent the reference column 2 from hitting the reference column under the inertia of the workpiece 11 when it is turned over. 3. It can play a buffer role.

Further, both ends of the rotating shaft 5 are provided with baffles 6, which can isolate external dust, and the reference column 3 is located on the centerline of the base plate 1, so that the space of the base plate 1 can be fully utilized.

Further, the number of the reference columns 3 is three to ensure the stable operation of the rotating seat 4 , and a lifting ring is installed on each of the four corners of the base plate 1 to facilitate the lifting and rotation of the large workpiece 11 .

The working principle of the utility model is as follows: first, the base plate 1 is lifted by the lifting ring, so that the reference vertical plate 2 is flush with the horizontal plane; And clamp it well, specifically through the pressing nail 12 and the piston plate 13 on the pressing plate 8 to complete, finally put the base plate 1 flat and fix it, then the milling process of the workpiece 11 can be started, after the processing is completed, the bolt 10 is loosened, at this time Turn over the reference vertical plate 2 to complete the exchange of the front and back of the workpiece 11, then install and tighten the bolts 10 to lock the reference vertical plate 2, and carry out the milling process in the next process, that is, the processing of at least two surfaces can be completed in one clamping, As for the workpiece 11 in the accompanying drawings in this specification, the machining of three surfaces can actually be completed, and of course it needs to be used together with a three-axis numerically controlled machining tool.
