Abstract
The utility model discloses an elastic clamp for clamping cup-shaped thin-wall parts. The clamp comprises a guide sleeve arranged in an inner hole of a main shaft of a machine tool by key joint. The clamp is characterized by also comprising a core shaft of which one end is in key joint with the guide sleeve, and a clamp body sleeved outside the core shaft, wherein the other end of the core shaft and one end of the clamp body are provided with a conical section and a conical hole which are matched; the clamp body is provided with a plurality of axial grooves distributed uniformly on the circumference; the other end of the clamp body is arranged in the inner hole of the main shaft of the machine tool and provided with a conical section matched with the inner hole; a locking sleeve arranged at the end of the main shaft of the machine tool through threads is arranged outside the clamp body; and the locking sleeve is tightly attached to the end face of the clamp body. The clamp has the advantages of high clamping speed and high production efficiency, can well meet the coaxiality requirement of the external circle of a workpiece and the inner hole, and is good in product quality.
Description
Technical field
The utility model relates to a kind of spring chuck that is used for clamping cup type thin-walled parts.
Background technology
At present; When processing cup type thin-walled parts; Generally be employed in the reverse mode turning processing excircles that three-jaw self-centering chuck clamping workpiece inwall is installed on the instrument lathe, this mode clamping speed is slow, production efficiency is low, and distortion is bigger; Can not fine assurance excircle of workpiece and the axiality requirement of endoporus, product quality can't guarantee.
The utility model content
The purpose of the utility model is the above-mentioned deficiency to prior art; A kind of spring chuck of clamping cup type thin-walled parts is provided; It has, and clamping speed is fast, advantage of high production efficiency, and the axiality requirement of fine assurance excircle of workpiece of ability and endoporus, good product quality.
For achieving the above object; The spring chuck of the clamping cup type thin-walled parts of the utility model; Comprise through key connecting being loaded on the fairlead in the machine tool chief axis endoporus that it is characterized in that also comprising mandrel that an end connects with fairlead, be set in the outer clamp body of mandrel, the other end of mandrel is provided with awl section and the taper hole that matches with an end of clamp body; On clamp body, be provided with several axial groove at circumference uniform distribution; The other end of clamp body is loaded in the machine tool chief axis endoporus and is provided with the awl section that cooperates with endoporus, outside clamp body, also is provided with the lock sleeve that is loaded on the machine tool chief axis end through screw thread, and lock sleeve is close to the end face of clamp body.
During use, the main shaft pull bar is connected with fairlead, pulling main shaft pull bar, fairlead drives mandrel and moves together, and its awl section is the distending clamp body outwards, makes it produce strain, and the end swelling workpiece inwall of clamp body is accomplished clamping, otherwise then unloads workpiece; Use this fixture operation simple, quick, production efficiency is high, and the contact area of clamp body and workpiece is big, be out of shape little, the axiality requirement of fine assurance excircle of workpiece of ability and endoporus, good product quality.
Description of drawings
Fig. 1 is the front view of the utility model embodiment.
Fig. 2 is the A-A profile of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation.
By illustrated in figures 1 and 2; The spring chuck of this clamping cup type thin-walled parts; Comprise through key connecting and be loaded on mandrel 2 through thread connection of fairlead 1, an end and fairlead 1 in machine tool chief axis 9 endoporus, be set in the outer clamp body 3 of mandrel 2; The other end of mandrel 2 is provided with awl section 2a and the taper hole that matches with an end of clamp body 3, on clamp body 3, is provided with the axial groove 3a of three roads at circumference uniform distribution, and the other end of clamp body 3 is loaded in machine tool chief axis 9 endoporus and is provided with the awl section 3b that cooperates with endoporus; Outside clamp body 3, also be provided with the lock sleeve 4 that is loaded on machine tool chief axis 9 ends through screw thread, lock sleeve 4 is close to the end face of clamp body 3.
During use, main shaft pull bar 8 is connected pulling main shaft pull bar 8 with fairlead 1; Fairlead 1 drives mandrel 2 and moves together, and the outside distending clamp body of its awl section 2a makes it produce strain; The end swelling workpiece inwall of clamp body 3 is accomplished clamping, otherwise then unloads workpiece; Use this fixture operation simple, quick, production efficiency is high, and clamp body 3 is big with the contact area of workpiece, be out of shape little, the axiality requirement of fine assurance excircle of workpiece of ability and endoporus, good product quality.
