The author machines cylinder side plane in batch in, the clamping apparatus of this kind of different structure that used article introduction will improve work efficiency, reduce labor intensity, it can be machined on milling machine not only, also can use at planer, use convenient, work efficiency is tall, welcome by handlers. In machining process classics regular meeting encounters plane of treatment A, B (cylinder side is planar) spare parts, normally odd production uses 3 ungual chuck to install clip to undertake machining, if encounter batch production, use 3 ungual chuck to install clip treatment to expose a work efficiency again intensity of low, labor the malpractice such as man-hour of big, cost. We machine cylinder side plane in batch in, the clamping apparatus that used a kind of different structure will improve work efficiency, reduce labor intensity. Basis workshop condition state is optional the clamping apparatus of the need that can satisfy batch one kind to machine cylinder side plane, it can be machined on milling machine not only, also can use at planer, use convenient, work efficiency is tall, welcome by handlers. Clamping apparatus of 1 structure principle basically provides body, force plunger by bolt, clip 1, force plunger 2, when composition of elastic sleeve of system of liquid state model, fixed force plunger, mouth is being used, insert workpiece inside mouth elastic sleeve, come back with spanner close bolt in order to drive force plunger 1 move right. The system of liquid state model inside body of support clamping apparatus will deliver thrust to move force plunger 2 close mouth elastic sleeve come clamp workpiece. Wait for treatment to end, need loose bolt only, mouth elastic sleeve relies on the bounce of oneself to loosen automatically, can take next work conveniently. The system of liquid state model in this clamping apparatus is OK also small ball bearing is replaced. This clamping apparatus can hold clip, loose number at the same time workpiece, use convenient, efficiency tall, but demand of the precision that make is higher. Clamping apparatus basically provides composition of elastic sleeve of body, mouth, long force plunger, short force plunger, bolt to be in use process by clip, the Kong Zhong that workpiece inserts mouth elastic sleeve, come back with spanner close bolt makes towards the left of short force plunger mobile, the axial force of short force plunger moves up through oblique plane is delivered and driving long force plunger, stop to workpiece of clamp of elastic sleeve of very close mouth. After treatment ends, need loose bolt only, mouth elastic sleeve relies on oneself bounce pine to open work. This clamping apparatus is convenient without clamping apparatus in use process (when be being used can odd a) of clamp of one by one. Diameter of inside and outside of elastic sleeve of mouth of 2 technologies requirement is homocentric degree must not exceed Ø0.
08mm, cooperate clearance to be more than with workpiece 0.
1 ～ 0.
2mm, external diameter surface roughness is worth for Ra1.
6, internal diameter surface roughness is worth for Ra0.
8, exterior hardness 38 ～ 40HRC. Assure mouth elastic sleeve to cannot get off freely from clamping apparatus body. Clamping apparatus of system of liquid state model is pouring do not need to set air hole additionally when system of liquid state model. Force plunger fits tolerance is recommended for ØDH7/h6, exterior surface roughness is worth for Ra1.
6. If clamping apparatus chooses ball bearing to replace system of liquid state model, its diameter is Ø1 ～ Ø3. Clamping apparatus, the cant of long force plunger and short force plunger cooperates to contact an area to must amount to 70% above, and each other of two force plunger is 90 ° horn, recommend cant of long force plunger and axes to become 60 ° part.
