Abstract
The utility model relates to an eccentric three-jaw chuck clamp which is used for clamping a cylinder workpiece. The eccentric three-jaw chuck clamp comprises a chuck, three L-shaped soft jaws are uniformly distributed on an end face of the chuck, the inner wall of each soft jaw is an arc, the arc-shaped inner walls of the three soft jaws form a round workpiece clamping hole which is concentric with the outer wall of the cylinder workpiece, rotation center of the round workpiece clamping hole relative to the chuck is eccentric, eccentricity of the round workpiece clamping hole is equal to that of an eccentric hole of the cylinder workpiece, and a positioning pin used for fixing the cylinder workpiece is arranged on the bottom wall of the soft jaw farthest from the center of the chuck. The three soft jaws are arranged for clamping the cylinder workpiece to be machined and are designed to be of eccentric structures to enable eccentricity to be equal to that of the to-be-machined eccentric hole of the cylinder workpiece, the eccentric hole of the cylinder workpiece is concentric with the rotation center of a lathe spindle, and accordingly machining center milling is changed into numerically controlled lathe machining. The eccentric three-jaw chuck clamp is suitable for mass production, and production efficiency is improved.
Description
Technical field
The utility model relates to cylinder processing and loading clamp technical field, especially a kind of eccentric scroll chuck fixture.
Background technology
Cylinder is a vitals in air motor, and air motor is compressed-air actuated pressure energy to be converted to the device of the mechanical energy of rotation.Its effect is equivalent to motor or hydraulic motor, namely exports torque and rotates with driving mechanism.
Cylinder workpiece such as Fig. 1 are shown in Figure 2, produce this part and will just can complete through following operation, and lateral aperture-boring eccentric orfice-deburring-chemical nickel plating-pressing steel balls hole-is bored in cast blank-finish turning 1-finish turning 2-brill locating hole-groove milling.Wherein the boring eccentric orfice is one critical process, to process eccentric orfice 4 in cylinder workpiece diagram, according to the requirement of cylinder detail drawing, the material of this part is Birmasil, cylinder eccentric orfice 4 is Ra0.8 in the roughness of side and bottom surface requirement, and root requires clear angle, so present this processing mode can not guarantee the quality requirement of cylinder.
The utility model content
The technical problems to be solved in the utility model is: in order to overcome the deficiencies in the prior art, a kind of eccentric scroll chuck fixture is provided, change the machining center Milling Process into lathe turning processing, existing cylinder is milled eccentric hole clamp to be improved, cast aluminium alloy material for cylinder, select suitable turning cutting tool and cutting parameter, car cutting cylinder eccentric orfice.
the technical scheme that its technical problem that solves the utility model adopts is: a kind of eccentric scroll chuck fixture, be used for clamping cylinder workpiece, comprise chuck, be evenly equipped with three soft pawls on the end face of described chuck, described soft pawl is all L-shaped, three soft pawl inwalls are circular arc, the circular-arc inwall of three soft pawls consists of the clamping workpiece circular hole, described clamping workpiece circular hole and cylinder workpiece outer wall concentric, described clamping workpiece circular hole is eccentric with respect to the chuck pivot, its eccentric throw is identical with the eccentric throw of the eccentric orfice of cylinder workpiece, with be provided with the alignment pin that the cylinder workpiece is fixing on the diapire of chuck hub distance soft pawl farthest.
Further, the diapire of described each soft pawl guarantees that the end face of cylinder workpiece can develop with soft pawl diapire at grade.
The beneficial effects of the utility model are, the utility model clamps by three soft pawls are set the cylinder workpiece that will process, three soft pawls are designed to eccentric structure, make it the eccentric orfice eccentric throw that to process with the cylinder workpiece identical, make the eccentric orfice of cylinder workpiece concentric with the lathe spindle pivot, realize the machining center milling is made into the purpose of lathe in machining with this, be fit to produce in enormous quantities, improved production efficiency.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of cylinder workpiece;
Fig. 2 is the structural representation of the A-A of Fig. 1;
Fig. 3 is the front view of eccentric scroll chuck fixture of the present utility model;
Fig. 4 is the structural representation of the B-B of Fig. 3;
Structural representation when Fig. 5 is the utility model clamping cylinder workpiece.
In figure: 1. chuck, 2. soft pawl, 3. clamping workpiece circular hole, 4. cylinder workpiece, 41. eccentric orfices, 5. alignment pin, 6. pin-and-hole.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
as shown in Figure 5 in Fig. 3 Fig. 4, this bias scroll chuck fixture, be used for clamping cylinder workpiece 4, comprise chuck 1, be evenly equipped with three soft pawls 2 on the end face of chuck 1, soft pawl 2 is all L-shaped, three soft pawl 2 inwalls are circular arc, the circular-arc inwall of three soft pawls 2 consists of clamping workpiece circular hole 3, clamping workpiece circular hole 3 and cylinder workpiece 4 outer wall concentrics, clamping workpiece circular hole 3 is eccentric with respect to chuck 1 pivot, its eccentric throw is identical with the eccentric throw of the eccentric orfice 41 of cylinder workpiece 4, with be provided with the alignment pin 5 that cylinder workpiece 4 is fixing on the diapire of chuck 1 centre distance soft pawl 2 farthest, the diapire of each soft pawl 2 at grade.By being set, three soft pawls 2 clamp the cylinder workpiece 4 that to process, three soft pawls 2 are designed to eccentric structure, make it eccentric orfice 41 eccentric throws that to process with cylinder workpiece 4 identical, make the eccentric orfice 41 of cylinder workpiece 4 concentric with the lathe spindle pivot, realized the machining center milling is made into the purpose of lathe in machining with this, be fit to produce in enormous quantities, improved production efficiency.
The concrete using method of this fixture is as follows: the pin-and-hole 6 of alignment pin 5 being aimed at cylinder workpiece 4, then cylinder workpiece 4 is pushed clamping workpiece circular hole 3, the head of cylinder workpiece 4 contacts with the diapire face of each soft pawl 2, and then lock three soft pawls 2, as Fig. 5, can find out, the pivot of the eccentric orfice 41 that cylinder workpiece 4 will be processed is consistent with the main shaft pivot, at this moment adopts turning processing just very convenient.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to the claim scope.
