Abstract
A pneumatic clamp for drilling a vibration damper is characterized in that a drill plate (5), a positioning base (3) and a clamp base (7) are sequentially connected from top to bottom through two guide pillars (2) arranged on the left and the right; the cylinder (1) is connected with the bottom of the positioning base (3), and the workpiece (6) is connected with the top of the positioning base (3); the sliding sleeve (4) is arranged at the upper part of the joint of the positioning base (3) and the two guide columns (2); the cylinder (1) moves up and down and simultaneously drives the movable positioning base (3) and the workpiece (6) to move up and down together in the two guide columns (2) through the sliding sleeve (4). The device adopts the pneumatic clamp to realize that the cylinder firmly locks the drilled workpiece in the clamp after jacking, so that the workpiece does not generate relative displacement during drilling, and the part is qualified.
Description
Technical Field
The invention relates to the technical field of automobile manufacturing, in particular to a pneumatic clamp for drilling a shock absorber.
Background
The drilling clamp of the existing product mainly clamps and stabilizes the workpiece to be drilled through bolt threads.
The traditional drilling fixture comprises a positioning mandrel, a drilling template, a screw, a gland, a positioning pin and other parts. A workpiece needing drilling is firstly sleeved on the positioning mandrel, then a drilling template and a gland are placed on the workpiece, finally, the bolt is manually tightened, and the workpiece is guaranteed to be pressed through the torque of the bolt. After the first hole is drilled, the workpiece is inserted into the positioning pin (to prevent the workpiece from moving relatively). And then, completing the drilling operation of other hole positions, loosening the bolts after all the holes are drilled, dismounting the gland, the drill plate and the workpiece, and entering the next cycle.
Because the traditional drilling process is tedious, the labor intensity is high, and the efficiency is low. Fatigue or loosening can occur in long-time manual operation, bolts are not tightened, and torque is insufficient; or after the first hole is drilled, no positioning pin is inserted, and the like, the workpiece to be drilled and the drilling template move relatively, and finally the part is unqualified. The risk of poor product consistency and low qualification rate exists.
Disclosure of Invention
Aiming at the problems, the invention reduces the procedures of manually filling the drill plate, tightening and loosening the bolts, inserting and pulling the positioning pins, has controllable air pressure and consistent pressure in the jacking process of the air cylinder, ensures the size and the position of the hole without displacement of a workpiece during drilling, reduces the labor intensity and improves the working efficiency.
In order to achieve the purpose, the invention adopts the following technical scheme: a pneumatic clamp for drilling a vibration absorber comprises a cylinder (1), a guide pillar (2), a positioning base (3), a sliding sleeve (4), a drilling template (5), a workpiece (6) and a clamp base (7);
the drilling template (5), the positioning base (3) and the clamp base (7) are sequentially connected from top to bottom through two guide pillars (2) arranged on the left and right; the cylinder (1) is connected with the bottom of the positioning base (3), and the workpiece (6) is connected with the top of the positioning base (3); the sliding sleeve (4) is arranged at the upper part of the joint of the positioning base (3) and the two guide columns (2); the cylinder (1) moves up and down and simultaneously drives the movable positioning base (3) and the workpiece (6) to move up and down together in the two guide columns (2) through the sliding sleeve (4).
The invention has the beneficial effects that: the device adopts the pneumatic clamp to realize that the cylinder firmly locks the drilled workpiece in the clamp after jacking, so that the workpiece does not generate relative displacement during drilling, and the part is qualified.
Drawings
FIG. 1 is a schematic diagram of a prior art structure; the device comprises a positioning mandrel (1), a drilling template (2), a bolt (3), a pressing plate (4) and a workpiece (5).
Fig. 2 is a schematic structural diagram of the device.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
As shown in figure 2, the pneumatic clamp for drilling the vibration absorber comprises a cylinder (1), a guide pillar (2), a positioning base (3), a sliding sleeve (4), a drilling template (5), a workpiece (6) and a clamp base (7).
All the tools are made of 45 #. The fixture base (7), the drill plate (5) and the positioning base (3) are connected through two guide pillars (2) on the left and right, the cylinder (1) is connected with the positioning base (3), and the cylinder (1) moves up and down and drives the positioning base (3) and the workpiece (6) to move up and down in the two guide pillars (2) through the sliding sleeve (4).
The invention has the beneficial technical effects that: compared with the traditional scheme, the process of manually tightening and loosening the bolt is omitted. Has the advantages of simple operation; the risk of manual clamping tightness or missing insertion of the positioning pin is reduced; the size is guaranteed to be more stable, the labor intensity is reduced, and the manufacturing and labor cost is reduced.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
