Abstract
The invention relates to a three-jaw chuck, which comprises a three-jaw chuck body. Three bevel gears of the three-jaw chuck body are respectively provided with clamping structures; the shape of the clamping structures which are respectively arranged on the three bevel gears corresponds to that of corresponding parts of a machined workpiece; after the machined workpiece is clamped in the clamping structure, the axis of the machined workpiece corresponds to that of the three-jaw chuck body. After the three-jaw chuck is adopted, repeated positioning performance is high and a clamping point is uniformly stressed in the process of machining the workpiece, so the problem of hole deformation is effectively solved; and the three jaws are convenient and firm to clamp and output per shift is improved to about 70 workpieces. In addition, different clamping structures are replaced for different workpieces by using the standard three-jaw chuck body.
Description
Technical field
The invention belongs to the Machining Technology field, specifically is a kind of scroll chuck of special-shaped workpiece processing usefulness.
Background technology
In the prior art, when processing the irregular workpiece of some profiles (for example housing among Fig. 1), all be difficult to clamping with the three-jaw and the four paws frock of standard.In order to address this problem, some frocks are also arranged, half sleeve shaped frock for example shown in Figure 2, workpiece 1 is adjusted the workpiece pressing profile with step plane of orientation in the frock main body 2.2 with screw rod 2.3, locks rear fender 2.4 again.Adjust unbalance stress after the profile but four screw rods compress a little, cause that processing back bore deformation is bigger.Add that clamping adjusts loaded down with trivial detailsly, scruple distortion clamping screw and rear fender pressure are less, and influence adds reasons such as the rotating speed in man-hour and depth of cut feed, and class's output is only about 28.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the present invention proposes a kind of special-shaped workpiece that is applicable to, the scroll chuck of housing processing particularly, and concrete technical scheme is as follows:
A kind of scroll chuck comprises the scroll chuck body, on three umbrella teeth of scroll chuck body the screens structure is set respectively; Described to be located at three screens structures on the umbrella tooth respectively corresponding with the profile of the appropriate section of workpiece to be machined, and after workpiece to be machined was clamped in the screens structure, the axle center of workpiece to be machined was corresponding with the axle center of scroll chuck body.
Described screens structure was fixedly connected or removably connects with being connected of umbrella tooth separately.
Described screens structure is to realize by welding with the mode of fixedlying connected of umbrella tooth separately.
Described screens structure with the implementation structure of the mode that removably connects of umbrella tooth separately is, be provided with corresponding slide rail and chute in the bottom of umbrella tooth top and screens structure, end at slide rail and/or chute is provided with retention device, make the screens structure on the rightabout of the center of circle of scroll chuck body, can not skid off the umbrella tooth.
Corresponding to the profile of workpiece to be machined, the screens structure also has multiple, and it is identical that the bottom of multiple screens structure is provided with corresponding slide rail or chute, promptly is standard component.
After adopting this scroll chuck, in the workpiece process, resetting is good, and bite is stressed evenly, has solved the difficult problem of bore deformation effectively, adds that the three-jaw convenient mounting and clamping is firm, and class's output rises to about 70.And, can utilize the scroll chuck body of standard, be directed to different workpieces and change different screens structures.
Description of drawings
Fig. 1 is the housing in the background technology;
Fig. 2 is half a sleeve shaped frock in the background technology;
Fig. 3 is the schematic diagram that the technical program is processed workpiece shown in Figure 1.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing and the specific embodiment.
A kind of scroll chuck comprises scroll chuck body 3.1, on three umbrella teeth 3.2 of scroll chuck body 3.1 screens structure 3.3 is set respectively; Described to be located at three screens structures 3.3 on the umbrella tooth 3.2 respectively corresponding with the profile of the appropriate section of workpiece to be machined, and after workpiece to be machined was clamped in the screens structure 3.3, the axle center of workpiece to be machined was corresponding with the axle center of scroll chuck body 3.1.
Described screens structure 3.3 was fixedly connected or removably connects with being connected of umbrella tooth 3.2 separately.
Described screens structure 3.3 is to realize by welding with the mode of fixedlying connected of umbrella tooth 3.2 separately.
Described screens structure 3.3 with the implementation structure of the mode that removably connects of umbrella tooth 3.2 separately is, be provided with corresponding slide rail and chute in the bottom of umbrella tooth 3.2 tops and screens structure 3.3, end at slide rail and/or chute is provided with retention device (for example block), make the screens structure on the rightabout of the center of circle of scroll chuck body, can not skid off umbrella tooth 3.2.
Corresponding to the profile of workpiece to be machined, the screens structure also has multiple, and it is identical that the bottom of multiple screens structure is provided with corresponding slide rail or chute, promptly is standard component.
Claims (5)
