Abstract
The invention discloses a cutting-force-resistant wedge type automatic auxiliary support device which is used for milling large workpieces. The cutting-force-resistant wedge type automatic auxiliary support device is characterized in that a base of the support device is mounted on a fixture bottom plate; a cylinder is fixed into the base, a wedge is driven by a push rod to move, and the cylinder is an oil cylinder or air cylinder; a wedge guide sleeve is arranged on the upper end surface of the cylinder; an ejector rod guide sleeve perpendicularly penetrates the wedge guide sleeve, an ejector head is fixed onto a support push rod, the support push rod is arranged in the ejector rod guide sleeve with a dustproof ring, one end of a spring is fixed into a spring sleeve arranged on the base, the other end of the spring is in contact with the wedge, the wedge in the wedge guide sleeve is pushed to move in the wedge guide sleeve, and the support push rod clamped on the wedge is driven to extend to be in contact with a part. The cutting-force-resistant wedge type automatic auxiliary support device has the advantages that the cutting-force-resistant wedge type automatic auxiliary support device is in an integral fixing unit design, the wedge is jointly pushed by the spring and the oil cylinder (or air cylinder), so that powerful and reliable supporting force can be generated to automatically support the part, the part machining quality and the process stability can be improved, and the cutting-force-resistant wedge type automatic auxiliary support device is low in labor intensity and high in interference resistance and universality.
Description
Technical field
The present invention relates to machinery manufacturing technology field, specifically the automatic auxiliary support apparatus of a kind of Wedge type of the cutting resistance for the large-scale workpiece Milling Process.
Background technology
For the Milling Process of slim and heavy parts, the crudy that how to prevent part machining deformation and raising part is a tackling key problem difficult problem of mechanical processing industry at present.Existing solution is to pass through screw rod jackscrew support part from the side on column, with this, reduces vibrations, although this method is simple, repeatability is poor also unreliable, and has following drawback.
1, easily cause the part self-deformation.In process of production, the workman carrys out the supplemental support part by twisting screw rod jackscrew, and either large or small all being difficult to of the screw-down torque of each use controlled, and top power is too large, and part easily produces distortion, after Milling Process, passes through the work piece inspection, and size is the out-of-size scope; Top power is too little, and jackscrew does not just reach part at all, can't play the effect of supplemental support workpiece, affects crudy.
2, the workman is inconvenient to operate, and labour intensity is also large.In real production process, according to processed part difference, on one sleeve clamp often will with a plurality of bracing or strutting arrangements be distributed in part around, this just needs manually twist one by one the support effect of screw rod examination device, has increased workman's labour intensity and psychological pressure.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present invention is to provide a kind of cutting resistance Wedge type automatic auxiliary support apparatus, to be used for preventing the thermal deformation that part produces when cutting, improve crudy and the technology stability of part, effectively reduce workman's labour intensity.
For achieving the above object, pedestal of the present invention is installed on clamp bottom board; Cylinder body is fixed in pedestal, by push rod, drives the wedge motion, and cylinder body is oil cylinder or cylinder; Cylinder upper end face is equipped with the wedge guide pin bushing, the push rod guide pin bushing is vertically through the wedge guide pin bushing, top is fixed on to be supported on push rod, supporting push rod is placed in the push rod guide pin bushing with dust ring, one end of spring is fixed in the spring housing be loaded on pedestal, the other end contacts with wedge, and the wedge promoted in the wedge guide pin bushing moves in the wedge guide pin bushing, drives the support push rod be stuck on wedge and stretches out and withstand on part.
The present invention adopts the design of integral type fixed cell, by spring and oil cylinder (or cylinder), combines the promotion wedge, enables the automatic stand part, and produces powerful reliable support force by the self-locking effect of wedge.
The present invention compared with prior art, has following advantage.
1, reliability is high, and support force is powerful.What this device supplemental support part provided power is spring, and the artificial torsion of the elasticity rate of spring can make the more reliable and more stable and contact part all the time in top, and the large I of elastic force adjusts by the length of spring, easily controls.After elastic force is adjusted, just can keep this stable elastic force to offer wedge always, support push rod when being subject to the Milling Process jarring forces, it is passed to wedge, the characteristic of now wedge utilization energy self-locking, make to support push rod, wedge and device body become one firmly whole, for the milling of part provides powerful support force, stop the vibrations of part when milling, improve the suface processing quality of part.
2, can effectively alleviate workman's labour intensity.Due to what adopt, be that spring and oil cylinder (or cylinder) interlock provide power, the action that only needs manually outside lathe action button to control oil cylinder (or cylinder) gets final product.
3, strong interference immunity, reliable and stable.What the present invention adopted is dustproof and built-in design, during Milling Process, can not affect because of iron pin and cutting fluid automatic operation and the supplemental support effect of device.
4, highly versatile, be widely used.What the present invention adopted is integrated design, for irregular piece surface, only need adjust according to the difference of part to be processed the length of top when the global design of fixture, and not need to redesign other device, this device overall applicability is gone to get final product to the fixture of like parts.
The accompanying drawing explanation
Fig. 1 is structure diagram of the present invention.
The specific embodiment
As shown in Figure 1, pedestal 6 is installed on clamp bottom board 13; Cylinder body 4 is fixed in pedestal 6, by push rod 5, drives wedge 2 motions, and cylinder body 4 is oil cylinder or cylinder; Wedge guide pin bushing 11 is equipped with in cylinder body 4 upper surfaces, push rod guide pin bushing 10 is vertically through wedge guide pin bushing 11, top 8 is fixed on to be supported on push rod 3, supporting push rod 3 is placed in the push rod guide pin bushing 10 with dust ring 9, one end of spring 1 is fixed in the spring housing 12 be loaded on pedestal 6, and the other end contacts with wedge 2, promotes the interior wedge 2 of wedge guide pin bushing 11 in the interior motion of wedge guide pin bushing 11, drive is stuck in support push rod 3 on wedge 2 and stretches out and withstand on part 7, with supplemental support workpiece 7.
Operation principle of the present invention.
While 1, unclamping, push rod 5(oil cylinder or cylinder) stretch out, wedge 2 is upwards pushed away, support push rod 3 is along with the motion of wedge 2 moves right.
While 2, working, push rod 5(oil cylinder or cylinder) return, now wedge 2 and push rod 5(oil cylinder or cylinder) separate, wedge 2 moves down under the effect of spring 1, supports push rod 3 and is ejected along with the motion of wedge 2, leans on part 7, because wedge 2 is self-locking devices, can resist the vibrations that Tool in Milling part 7 produces in the rear generation self-locking of contact part 7 so support push rod 3, thereby reach the purpose of supplemental support part 7.
