Description
Technical Field
The utility model belongs to the technical field of aluminum casting machine tooling, a broken face processing centre gripping frock of tube-shape aluminum casting lateral wall is related to.
Background
As shown in fig. 1, a platform a is disposed on a side surface of the cylindrical aluminum casting, and a through hole B is disposed in the platform a, but the through hole B in the aluminum casting blank obtained by die casting is closed, and the through hole B and a ring groove C at the hole opening need to be milled by a machining method. The body of tube-shape aluminium casting is the column, can't directly press from both sides the dress on the lathe, needs to adopt the supplementary centre gripping of centre gripping frock. An existing clamping tool is shown in fig. 2, three positioning holes D in the bottom of an aluminum casting are used for positioning the casting in the tool, and a pneumatic pressing plate E is used for clamping the casting in the tool. However, the cutting force generated by the cutting tool causes a gap between the casting and the pressure plate, and further causes the casting to be displaced laterally, which affects the processing quality of the through hole B and the ring groove C.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: how to avoid the casting from generating transverse displacement during cutting and processing and ensure the processing quality of the through hole and the ring groove.
In order to achieve the above purpose, the utility model provides a technical scheme as follows:
tubular aluminum casting lateral wall broken face processing centre gripping frock, including vertical tool board of placing, and set up pneumatic expansion cylinder, pilot pin and pneumatic clamp plate on the tool board, the pilot pin is fixed in the side of tool board, the expansion cylinder core of pneumatic expansion cylinder fix the tool board the side and with the pilot pin homonymy, the plate of pneumatic clamp plate is located the side of tool board with the pilot pin homonymy.
Compared with the prior art, the beneficial effects of the utility model are that: the location of foundry goods is realized to the pilot pin, and the centre gripping of foundry goods is realized to outside pneumatic clamp plate, increases the inside of pneumatic expansion cylinder from the aluminium foundry goods and carries out the centre gripping, and dual centre gripping can avoid the foundry goods to take place lateral displacement when cutting man-hour, has guaranteed the processingquality of through-hole and annular.
Drawings
In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly described below.
FIG. 1 is a view showing a structure of a tubular aluminum casting in the prior art;
FIG. 2 is a structural diagram of a clamping tool in the prior art
FIG. 3 is a top view of the clamping fixture disclosed in the examples;
fig. 4 is a structural view of the clamping tool disclosed in the embodiment.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Examples
Please refer to the clamping fixture shown in fig. 3, which includes a vertically disposed fixture plate 10, two sets of pneumatic expansion cylinders 20, two sets of positioning pins 30 and a pneumatic pressing plate 40, wherein the two sets of pneumatic expansion cylinders 20, the two sets of positioning pins 30 and the pneumatic pressing plate 40 are disposed on the fixture plate, the positioning pins are fixed on the side surface of the fixture plate, the expansion cylinder core of the pneumatic expansion cylinder is fixed on the side surface of the fixture plate and on the same side as the positioning pins, the plate of the pneumatic pressing plate is located on the same side as the positioning pins, the pneumatic pressing plate is disposed between the two sets of positioning pins, and two ends of the plate.
The aluminum casting in the figure 1 is placed on the side face of the jig plate, the positioning pin is inserted into the positioning hole D of the aluminum casting to achieve positioning of the casting, the casting is pressed on the jig plate through the pneumatic pressing plate to achieve clamping of the casting, and the expansion cylinder core of the pneumatic expansion cylinder expands outwards to be clamped from the interior of the aluminum casting. The double clamping of the pneumatic pressing plate and the expansion cylinder core can avoid the transverse displacement of the casting during cutting and processing, and ensure the processing quality of the through hole and the ring groove.
Referring to fig. 4, the pneumatic pressing plate includes a cylinder 41, a connecting rod 42 and a plate 43, the cylinder is fixed on the other side of the jig plate, and the connecting rod passes through the jig plate and is connected with the plate; the one end that the connecting rod corresponds the plate is the screw thread end, is provided with two nuts 44 on this screw thread end, and the bottom of plate is provided with U type draw-in groove, and the screw thread end of connecting rod is located U type draw-in groove 431, and two nuts press to paste the both sides at the plate and fix it. After the aluminum casting is processed, the expansion cylinder core contracts inwards to release the aluminum casting, one nut is unscrewed, the plate is detached, and the aluminum casting can be taken out.
A cover plate 50 for covering the pneumatic components in the pneumatic expansion cylinder and the pneumatic pressing plate is arranged at the top of the jig plate, so that the pneumatic components are prevented from being damaged by milled metal scraps.
Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
