Abstract

A kind of clamping device, is made up of sleeve, spring, handle, scale, quill, clamp-screw, chuck; Described sleeve is a U-iron block; Described handle is connected with quill top; Described scale is located at above sleeve; Described spring is located in sleeve; Described quill is located in sleeve, is matched in clearance with sleeve; Described clamp-screw is located at chuck top; Described chuck installs bolt die, can be used to external threading.The utility model structure is simple, easy to manufacture, it is convenient to change, and can greatly raise labour productivity in process of production, improves the qualification rate of product, the spoilage that simultaneously also can reduce cutter and the workpiece repair rate caused because of tool damage.

Description

A kind of clamping device
Technical field
The utility model relates to field of machining, particularly relates to a kind of clamping device.
Background technology
Short thread processed by engine lathe, general all employing bolt die or screw tap (hand-held or fixing), the opportunity of screw tool incision and the more difficult grasp of size of cutting-in force, the length of machining screw is also uncontrollable simultaneously, not only machining accuracy is low, production efficiency is low, and labour intensity is large, percent defective is high.
Utility model content
In view of in prior art, easily cause when processing work waste and working (machining) efficiency is lower.The purpose of this utility model is to provide a kind of clamping device.
In order to achieve the above object, technical solution adopted in the utility model is as follows:
A kind of clamping device, is made up of sleeve, spring, handle, scale, quill, clamp-screw, chuck; Described sleeve is a U-iron block; Described handle is connected with quill top; Described scale is located at above sleeve; Described spring is located in sleeve; Described quill is located in sleeve, is matched in clearance with sleeve; Described clamp-screw is located at chuck top; Described chuck installs bolt die, can be used to external threading.
Advantage of the present utility model and beneficial effect are: structure is simple, easy to manufacture, replacing is convenient, can greatly raise labour productivity in process of production, improve the qualification rate of product, the spoilage that simultaneously also can reduce cutter and the workpiece repair rate caused because of tool damage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in Figure 1 be structural representation of the present utility model, a kind of clamping device, is made up of sleeve 1, spring 2, handle 3, scale 4, quill 5, clamp-screw 6, chuck 7; Described sleeve 1 is a U-iron block; Described handle 3 is connected with quill 5 top; Described scale 4 is located at above sleeve 5; Described spring 2 is located in sleeve 1; Described quill 5 is located in sleeve 1, is matched in clearance with sleeve 1; Described clamp-screw 6 is located at chuck 7 top; Described chuck 7 installs bolt die, can be used to external threading.During operation, first this device is inserted tail stock, make cutter close to workpiece to be processed.Fixing tailstock, starts lathe.Rotate tailstock handle, make cutter and absorption surface, along with the advance of this clamping device, cutter and workpiece, by spring compression, make cutter accurately can cut workpiece with spring thrust.After cutter correctly cuts workpiece, stop operating handle, and the thrust of spring increases gradually and reduces, until screw tool band moving sleeve 1 realizes feeding voluntarily along with the cut-in length of cutter.Now quill 5 is with the displacement of fixed handle 3 relative sleeve 1, determines the length of machining screw thus.After reaching regulation reach, drive anti-car and return tailstock feeding handle, cutter just exits automatically, stops, completes screw thread process operation.In order to improve the machining accuracy of this instrument, can according to the instrument of different part technical requirements preparation different size.
