The utility model discloses a clamp for a double-guided boring machine, which comprises a clamp body, a cylindrical boss is arranged on the top of the clamp body, a bearing sleeve is arranged at both ends of the cylindrical boss, and a lining is arranged in the bearing sleeve. The sleeve is provided with a boring sleeve in the bush; symmetrical support plates are arranged on both sides of the top of the cylindrical boss, and symmetrical workpiece pressing devices are arranged on both sides of the cylindrical boss. The utility model adopts two guiding mechanisms formed by the combination of the support sleeve, the sleeve and the boring sleeve, and uses the two guiding mechanisms to process two coaxial holes with different sizes synchronously. The clamping process is simple, the processing is convenient, and the processing accuracy is high. High, reducing the labor intensity of workers and improving work efficiency. The utility model has the advantages of simple structure, low cost and good use effect.
Description
Technical field
The utility model relates to a kind of mechanical field, especially a kind of two guiding fixture for boring machine.
Background technology
At present, the conventional brace of transmission case is mainly to adopt universal fixturing, and universal fixturing exists clamping difficulty, and machining accuracy is low, needs the problems such as calibration, makes part processing cost higher.Therefore, in production and processing, for addressing the above problem, generally adopt corresponding special fixture to fix, the labour intensity when using exclusive clamps prodigiosin instead and effectively reducing work, raise labour productivity, and obtain higher machining accuracy.But the scope of application of special fixture is less, only in the bore hole part of a certain part of processing.
Summary of the invention
The purpose of this utility model is: a kind of two guiding fixture for boring machine is provided, and its machining accuracy is high, and installation way is simple, can process the exclusive clamps of two coaxial apertures, to overcome the deficiencies in the prior art simultaneously.
The utility model is achieved in that two guiding fixture for boring machine, comprises clamp body, at the top of clamp body, is provided with cylinder boss, at the two ends of cylinder boss, is provided with support base sleeve barrel, is provided with lining in support base sleeve barrel, is provided with bushing in lining; Both sides, top at cylinder boss are provided with symmetrical support plate, in the both sides of cylinder boss, are provided with symmetrical workpiece pressuring clamping device.
Workpiece pressuring clamping device comprises hook pressure plate, the bottom of hook pressure plate is provided with hook-shaped pressing plate lining, the bottom of hook-shaped pressing plate lining in clamp body, separately be provided with connecting bolt, the bottom of connecting bolt is successively through hook pressure plate, hook-shaped pressing plate lining and clamp body, below clamp body, be provided with driver plate, driver plate is connected with the bottom of two connecting bolts.
Between hook pressure plate and connecting bolt, be provided with Bolt to position pin; Between clamp body and hook pressure plate, be provided with hook pressure plate alignment pin.Bolt to position pin can prevent that connecting bolt from rotating, and hook pressure plate alignment pin can prevent that hook pressure plate from rotating.
At the two ends, top of cylinder boss, be respectively equipped with straight pin and rhombus pin.Straight pin and rhombus pin are mainly movement on position level face and 4 direction frees degree of rotation.
Owing to having adopted technique scheme, compared with prior art, the utility model adopts two guiding mechanisms that are combined to form by support base sleeve barrel, village's cover and bushing, utilize two coaxial apertures that vary in size of these two guiding mechanism synchronous processings, clamping process is simple, easy to process, and machining accuracy is high, alleviate labor strength, improved operating efficiency.The utility model is simple in structure, with low cost, and result of use is good.
