Abstract
The utility model discloses a cutting force-resistant wedge type automatic auxiliary supporting device which is applicable to milling processing of large workpieces. A base of the supporting device is installed on a fixture bottom plate, a cylinder is fixed inside the base and drives a wedge to move through a push rod, the cylinder is an oil cylinder or an air cylinder, a wedge guide sleeve is installed on the upper end face of the cylinder, a top rod guide sleeve vertically penetrates through the wedge guide sleeve, a top head is fixed on a supporting push rod, the supporting push rod is placed inside the top rod guide sleeve with a dustproof ring, one end of a spring is fixed inside a spring sleeve which is installed on the base, and the other end of the spring contacts with the wedge, pushes the wedge inside the wedge guide sleeve to move inside the wedge guide sleeve and drives the supporting push rod clamped on the wedge to extend out to contact with a part. According to the cutting force-resistant wedge type automatic auxiliary supporting device, an integrated fixing unit design is adopted, and the wedge is pushed by the spring and the oil cylinder (or the air cylinder) together, so that the part is automatically supported by the large and reliable supporting force, the processing quality and the process stability of the part can be improved, the labor intensity is low, and the anti-interference performance and the generality are high.
Description
Technical field
The utility model relates to machinery manufacturing technology field, specifically a kind of automatic auxiliary support apparatus of cutting resistance Wedge type 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 from the side support part of screw rod jackscrew at column, reduces vibrations with this, although this method is simple, repeatability is relatively poor also unreliable, and has following drawback.
1, causes easily the part self-deformation.In process of production, the workman comes 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 usefulness controlled, and top power is too large, and part easily produces distortion, passes through the work piece inspection after Milling Process, 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, different according to processed part, on one sleeve clamp often will with a plurality of bracing or strutting arrangements be distributed in part around, the support effect that this just needs manually twist one by one screw rod and 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 utility model 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 utility model is installed on the clamp bottom board; Cylinder body is fixed in the pedestal, drives the wedge motion by push rod, 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, the top is fixed on to be supported on the 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 that is loaded on the pedestal, the other end contacts with wedge, and the wedge that promotes in the wedge guide pin bushing moves in the wedge guide pin bushing, drives the support push rod that is stuck on the wedge and stretches out and withstand on the part.
The utility model adopts the design of integral type fixed cell, unites the promotion wedge by spring and oil cylinder (or cylinder), enables the automatic stand part, and produces powerful reliable support force by the self-locking effect of wedge.
The utility model 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 is adjusted easily control by the length of spring.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, wedge utilization this moment can self-locking characteristic, make 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.Because what adopt is 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 utility model adopted is dustproof and built-in design, can not affect because of iron pin and cutting fluid automatic operation and the supplemental support effect of device during Milling Process.
4, highly versatile is widely used.What the utility model adopted is integrated design, for irregular piece surface, when the global design of anchor clamps, only need to adjust the length of top according to the difference of part to be processed, and need not redesign other device, this device overall applicability is gone to get final product to the anchor clamps of like parts.
Description of drawings
Fig. 1 is structure diagram of the present utility model.
The specific embodiment
As shown in Figure 1, pedestal 6 is installed on the clamp bottom board 13; Cylinder body 4 is fixed in the pedestal 6, drives wedge 2 motions by push rod 5, 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 the 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 that is loaded on the pedestal 6, and the other end contacts with wedge 2, and the wedge 2 in the promotion wedge guide pin bushing 11 is in the 11 interior motions of wedge guide pin bushing, drive is stuck in support push rod 3 on the wedge 2 and stretches out and withstand on the part 7, with supplemental support workpiece 7.
Operation principle of the present utility model.
When 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.
When 2, working, push rod 5(oil cylinder or cylinder) return, this moment 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 contact part 7 rear generation self-lockings so support push rod 3, thereby reach the purpose of supplemental support part 7.
