1, manually fast folder clamps: its drawback is that rubber tip is easy to breakage and causes folder not tight, if change irony or copper contact into, so because contact lacks flexibility and cushion effect presss from both sides not tight.
2, bolt locking: this kind method is no doubt better, and coupling mechanism force is bigger, but efficient is too low, can't adapt to the productive temp of the high modern process equipment of automaticity.
3, cylinder compresses: select a kind of cylinder, directly compress with cylinder, though this kind method is feasible, but because different cylinder pressures is inequality, power consumption does not wait, and volume is in different size, can cause bigger difference at aspects such as use, handling modes, and difference in selling prices is bigger.
The utility model content
Problem to be solved in the utility model provides a kind of simple in structure, easy to operate workpiece fast fixture, its objective is the clamping efficient of raising workpiece and the stability of clamping.
To achieve these goals, the technical scheme taked of the utility model is:
This fast fixture provided by the utility model comprises clamp body, cylinder, pressing plate and alignment pin, and workpiece is by described alignment pin location, and described pressing plate is a lever construction, and its centre of gyration carries out hinge by balance pivot and clamp body and is connected; Under the clamped state of described workpiece, an end of described pressing plate is connected with the piston rod on the cylinder, and the other end contacts with clamped workpiece 8.
For making the utility model more perfect, more detailed and concrete technical scheme below also further having proposed, to obtain best practical function, realize goal of the invention better, and improve novelty of the present utility model and creativeness:
Described balance pivot is the arm of force to the distance of pressing plate and cylinder link position; Described balance pivot is an actuation arm to the distance of pressing plate and workpiece contact position; The length of the described arm of force is greater than the length of actuation arm.
Described pressing plate is when clamping work pieces, and the end points that described cylinder promotes the arm of force moves upward, and promptly described workpiece is below described actuation arm.
The utility model adopts technique scheme, the utilization lever principle, and when adopting cylinder, the arm of force by lever construction increases the cylinder thrust, very easy and compacting processing workpiece fast more effectively.If use numerically controlled processing equipment, also can utilize the operation programming realize this device to the automatic clamping of work piece and unclamp, function such as clamping force is adjustable, reach accurate, quick, the stable clamping effect of workpiece to be machined.Simple in structure, can effectively improve part processing efficient, it is stable to realize processing beat, and the yield rate height is safe and convenient to use.Above-mentioned Pneumatic lever type fast fixture is applied to process alloy part such as vehicle steering steering column part has obtained success.Compare with conventional clamping device, work efficiency has improved more than 5 times, and has significantly improved the machining accuracy of this part.
Description of drawings
Below expressed content of each width of cloth accompanying drawing of this specification and the mark among the figure are briefly explained:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the schematic top plan view of structure shown in Figure 1.
Above-mentioned each figure acceptance of the bid note is respectively:
1, clamp body, 2, balance pivot, 3, pressing plate, 4, air cylinder base, 5, cylinder, 6, alignment pin, 7, workpiece.
The specific embodiment
Contrast accompanying drawing below, by description to embodiment, to effect and operation principle, the manufacturing process of the mutual alignment between the shape of the specific embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present utility model, technical scheme had more complete, accurate and deep understanding to help those skilled in the art.
The of the present utility model structure expressed as Fig. 1, Fig. 2, the utility model is a kind of fast fixture, comprises clamp body 1, cylinder 5, pressing plate 3 and alignment pin 6, workpiece 7 is by described alignment pin 6 location; Pressing plate 3 is connected with cylinder 5.
In order to solve the problem that exists at the described present known technology of this specification background technology part and to overcome its defective, realize improving the goal of the invention of the stability of the clamping efficient of workpiece and clamping, the technical scheme that the utility model is taked is:
Shown in Fig. 1 and Tu, this fast fixture provided by the utility model, described pressing plate 3 is a lever construction, its centre of gyration carries out hinge by balance pivot 2 with clamp body 1 and is connected; Under the clamped state of described workpiece 7, an end of described pressing plate 3 is connected with piston rod on the cylinder 5, and the other end contacts with clamped workpiece 7.Balance pivot 2 and alignment pin 6 are installed on the clamp body 1.
When machine direction dish steering column part, use above-mentioned clamping device, the utilization lever principle, when adopting cylinder, adopt an energy to increase the device of cylinder thrust by the arm of force, the active force that cylinder 5 applies is amplified by pressing plate 3 and is delivered on the workpiece 7, so just can be very easy and compacting processing workpiece 7 fast more effectively, and make the clamping of workpiece 7 more stable.
