Abstract
The utility model provides a clamping device special for a lathe. The clamping device comprises a chunk plate, a main shaft, an outer thread tapered pin, a positioning sleeve, and a locking nut, wherein the main shaft is a cylinder-shaped iron block, the chunk plate is a hollow flange-shaped iron block and is installed at one end of the main shaft, and the outer thread tapered pin is an iron block which is wide in upper portion and is narrow in lower portion, and is installed on the main shaft. The positioning sleeve is placed close to the outer thread tapered pin. The locking nut is arranged on the lower end of the outer thread tapered pin. The clamping device special for the lathe is mainly used for the circumstance that threaded holes processing is finished on one end of sleeve type parts, and the threaded holes or unthreaded holes processing can be conducted on the other end of the sleeve type parts, and then, the processed threaded holes are used for positioning and clamping. The clamping device special for the lathe is simple in structure, capable of assembling and disassembling workpieces conveniently, and high in efficiency.
Description
Technical field
The utility model relates to the clamping device of using in a kind of lathe processing.
Background technology
Machining accuracy is had relatively high expectations, and the machining accuracy that wherein how to guarantee workpiece in process is very important work.
Some sleeve part, right-hand member screwed hole (or unthreaded hole) has the axiality requirement with respect to the left end screwed hole, after having machined the left end screwed hole, need to carry out to the screwed hole (or unthreaded hole) of its right-hand member turning processing, if the external cylindrical surface location with left end clamps, can produce not coincidence error of benchmark on the one hand, produce easily on the other hand distortion; If adopt the screwed hole location to clamp, because the effect of cutting force will produce very large thrust at workpiece and abutment sleeve end face, after turning machined, workpiece inconvenience was unloaded.
The utility model content
In prior art, there is the shortcoming that dismounting is inconvenient, efficient is not high.The purpose of this utility model is to provide a kind of Special clamping device, adopts the screwed hole location that has processed to clamp, and has both guaranteed machining accuracy, has made things convenient for again the part loading and unloading, has improved efficient.
In order to achieve the above object, technical solution adopted in the utility model is as follows:
The utility model provides a kind of clamping apparatus for lathe, comprises chuck, main shaft, external screw thread taper bolt, abutment sleeve, stop nut; Described main shaft is a cylindrical iron block; Described chuck is a hollow flange shape iron block, is located at described main shaft one end; Described external screw thread taper bolt is a taper iron block wide at the top and narrow at the bottom; Described abutment sleeve is located on the main shaft, close external screw thread taper bolt setting; Described stop nut is located at described external screw thread taper bolt lower end.
According to above-mentioned design of the present utility model, an end surfaces of described spindle processing workpiece is provided with external screw thread.
According to above-mentioned design of the present utility model, described main shaft is provided with the taper hole with external screw thread taper bolt coupling.
Advantage of the present utility model and benefit are: simple in structure, workpiece loading and unloading is convenient, and efficient is high.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
In order to further specify principle of the present utility model and structure, now by reference to the accompanying drawings preferred embodiment of the present utility model is elaborated, yet described embodiment can not be used for limiting scope of patent protection of the present utility model only for furnishing an explanation and explaining a usefulness.
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
As shown in Figure 1 be a kind of lathe Special clamping device of the present utility model, comprise chuck 1, main shaft 2, external screw thread taper bolt 3, abutment sleeve 4, stop nut 5; Described main shaft 2 is a cylindrical iron block; Described chuck 1 is a hollow flange shape iron block, is located at described main shaft 2 one ends; Described external screw thread taper bolt is a taper iron block wide at the top and narrow at the bottom; Described abutment sleeve is located on the main shaft, close external screw thread taper bolt setting; Described stop nut is located at described external screw thread taper bolt lower end.
This kind Special clamping device utilizes the external screw thread on the main shaft 2 to realize radial location guaranteeing the axiality requirement of workpiece two ends screwed hole with the cooperating of internal thread on the workpiece.Utilize workpiece end face and abutment sleeve 4 end faces to compress and realize axial location and clamping.Utilize the axial location that realizes abutment sleeve 4 that cooperates of external screw thread taper bolt 3 and taper hole.Simultaneously, utilize the tapering of external screw thread taper bolt 3 and taper hole, threaded circular taper pin 3 pines step back outside, so that the pressure of abutment sleeve 4 end faces and workpiece end face is eliminated, are easy to unload workpiece.In order to prevent that lower outside threaded circular taper pin 3 pines of High Rotation Speed situation from moving back, and is provided with stop nut 5.
During use, external screw thread taper bolt 3 is inserted as in abutment sleeve 4 and the main shaft 2, and tightened stop nut 5, make abutment sleeve 4 axial location and fixing.Then workpiece is screwed on the main shaft 2, and compresses with abutment sleeve 4 end faces, after workpiece machines, unscrew stop nut 5, external screw thread taper bolt 3 pines are moved back, abutment sleeve 4 is eliminated with the thrust of workpiece end face unloaded part.The field shows that this Special clamping device can satisfy instructions for use, has both guaranteed the axiality requirement of left and right two ends screwed hole, has made things convenient for again the loading and unloading of part, has improved production efficiency.
Foregoing only is preferred embodiment of the present utility model and the mode of texturing enumerated; be not used for limiting the utility model; every within spirit of the present utility model and principle; any modification and the improvement that need not creative thinking done all should be included within the protection domain of the present utility model.
