Technical Field
The utility model belongs to the technical field of the assembly, a tight jig of cylinder class part once location clamp is related to.
Background
The traditional processing technique of the cylindrical parts adopts the most traditional bench work processing method, firstly, scribing is carried out, and then, drilling is carried out according to the scribing position. Such a machining method cannot ensure uniformity of machining dimensions, and requires repeated scribing for each machining.
In order to reduce the problem that the efficiency that the repeated marking off brought reduces, the size is non-uniform, the utility model provides a cylinder class part once only fixes a position drilling mould, and the part can drill under the condition that does not need the marking off, has not only simplified the marking off process, has guaranteed the uniformity of size moreover, has improved machining efficiency simultaneously.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a tight jig of cylinder class part once location clamp is applicable to the quick drilling processing of cylinder class part and guarantees machining dimension, radial symmetry uniformity.
The technical scheme of the utility model is that:
a one-time positioning and clamping jig for cylindrical parts comprises a base 1, a connection adjusting block 2, a low-pressure spring 3, a bolt 4, a bearing 5, a bearing seat 6, a V-shaped positioning drill bushing 7, a drill bit 8, a drilling machine spindle 9, a high-pressure spring 11 and a combining block 12.
The base 1 is used for placing a cylindrical workpiece 10, and the base 1 is provided with a connecting adjusting block 2 through a bolt 4. A V-shaped groove at the lower end of the V-shaped positioning drill bushing 7 is in penetrating connection with the adjusting block 2 and is in contact with the side face of the cylindrical workpiece 10, so that the center of the cylindrical workpiece 10 is positioned; the upper end of the V-shaped positioning drill bushing 7 is connected in the bearing seat 6 through a bearing 5. The center of the bearing seat 6 is communicated with a V-shaped positioning drill bushing 7. The low-pressure spring 3 is arranged on the V-shaped positioning drill bushing 7 and is positioned between the bearing seat 6 and the connecting adjusting block 2.
Furthermore, a waist-shaped groove 13 is formed in the connecting and adjusting block 2, the relative position of the connecting and adjusting block 2 and the base 1 is adjusted through the elastic bolt 4, the final hole edge distance of the workpiece is achieved, and machining of different hole distances of the side wall of the cylindrical part is achieved.
When the high-pressure spring type drilling machine is used, the drilling machine spindle 9 and the drill bit 8 feed downwards, and the high-pressure spring 11 and the combination block 12 descend together; in the descending process, the drill bit 8 firstly enters the bearing seat 6 and the V-shaped positioning drill bushing 7 in sequence, and the drill bit 8 continuously descends; the combination block 12 is contacted with the bearing seat 6, the bearing seat 6 rotates to drive the bearing 5 to rotate, the low-pressure spring 3 is compressed under the pressure of the high-pressure spring 11, and the V-shaped positioning drill bush 7 downwards presses the cylindrical workpiece 10 to realize positioning; the drill bit 8 continues to descend to compress the high-pressure spring 11 to realize drilling. Thereby ensuring that the centering and fixed-size drilling process is realized in one movement.
The utility model has the advantages that: cylinder class part once fix a position and press from both sides tight jig, the part can drill under the condition that does not need the rule, the cylinder work piece of different diameters can be adapted to in the V type groove of V type location drill bushing, not only simplify the marking off process, guaranteed the unity of size moreover, improved machining efficiency simultaneously.

Detailed Description
The following examples and drawings are provided to further explain the embodiments of the present invention, but are not intended to limit the present invention.
As shown in figure 1, the one-step positioning and clamping jig for cylindrical parts comprises a base 1, a connection adjusting block 2, a low-pressure spring 3, a bolt 4, a bearing 5, a bearing seat 6, a V-shaped positioning drill bushing 7, a drill bit 8, a drilling machine spindle 9, a high-pressure spring 11 and a combining block 12.
The base 1 is used for placing a cylindrical workpiece 10, and the base 1 is provided with a connecting adjusting block 2 through a bolt 4. A V-shaped groove at the lower end of the V-shaped positioning drill bushing 7 is in penetrating connection with the adjusting block 2 and is in contact with the side face of the cylindrical workpiece 10, so that the center of the cylindrical workpiece 10 is positioned; the upper end of the V-shaped positioning drill bushing 7 is in interference connection with the inner ring of the bearing 5; the outer ring of the bearing 5 is in interference connection with the bearing seat 6. And a through hole communicated with the V-shaped positioning drill bushing 7 is formed in the center of the bearing seat 6.
