A kind of numerically controlled lathe chuck structure of processing slow bonding steel strand anchorage intermediate plate
Technical field
The utility model belongs to the frame for movement technical field, especially relates to a kind of numerically controlled lathe chuck structure of processing slow bonding steel strand anchorage intermediate plate.
Background technology
In existing technology; As shown in Figure 1; Being used to process the slow numerically controlled lathe chuck structure that bonds the steel strand anchorage intermediate plate is that a centre bore is that diameter 8.5mm, length are that the multidiameter of 52mm, its structure are divided into three parts (i.e. three integrated axles) and form: first is the axle of long 15mm, diameter 48mm; Second is the axle of long 10mm, diameter 25mm; The 3rd is the axle of long 27mm, diameter 16mm, and wherein the 3rd is divided into four parts with axle, and its action principle is: the 3rd swells from inside to outside, the anchor clipper blank is clamped.
In the numerically controlled lathe course of work, because operator's operate miss or lathe break down, the 3rd of this chuck is easy to severed or miscue by lathe tool; Cause whole chuck to damage or appearance off-centre, thereby cannot continue processing work again, must change chuck; Exist and make chuck cost height; It is long to change the chuck time, and the adjustment lathe is wasted time and energy technical problems such as inefficiency.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of simple in structure, processing ease, slow bonding steel strand anchorage intermediate plate chuck that production efficiency is high, especially is fit to be convenient for changing when chuck damages chuck.
The technical scheme of the utility model is: a kind of numerically controlled lathe chuck structure of processing slow bonding steel strand anchorage intermediate plate; This chuck is a multidiameter structure; Comprise first, second and the 3rd, said first and second structure that is formed in one, the 3rd integrative-structure with first and second formation is separated; Said the 3rd end is link, and the other end is divided into four parts; Said second axle head is threaded with the 3rd link; On said second jackscrew is set, fixing with the 3rd with second.
Advantage and the good effect that the utlity model has are: adopt technique scheme; When chuck damages; The 3rd that only needs to change chuck get final product, and first and second do not need replacing, thereby has practiced thrift cost of manufacture; Reduce the time of changing chuck and the time of adjusting lathe, improved production efficiency.

The specific embodiment
Like Fig. 2, shown in Figure 3, a kind of numerically controlled lathe chuck structure of processing slow bonding steel strand anchorage intermediate plate of the utility model, this chuck are that a centre bore is that diameter 8.5mm, length are the separable multidiameter of 55mm, comprise first 1, second 2 and the 3rd 3; First 1 is the axle of long 15mm, diameter 48mm, and second 2 is axles of long 10mm, diameter 25mm, first 1 and second 2 structure that is formed in one; Is the internal thread of M16 at second 2 axle head with centre bore reaming tapping; The 3rd 3 is axles of long 37mm, diameter 16mm, is separated with first 1 and second 2 integrative-structure that forms; The 3rd M16 external screw thread link that 3 one ends are long 10mm, the other end is divided into four parts; Second 2 axle head is threaded with the 3rd 3 link; Get a jackscrew 4 on second 2, fixing with the 3rd 3 and second 2.
The course of work of this instance: the 3rd 3 is connected with second male thread, fixing with the jackscrew 4 on second 2 with the 3rd 3, the utility model is installed in the slow bonding of processing steel strand anchorage intermediate plate on the numerically controlled lathe.In the numerically controlled lathe course of work, because operator's operate miss or lathe break down, when the 3rd 3 of this chuck severed or miscue by lathe tool; The 3rd 3 with the utility model is unloaded; The 3rd 3 that only needs to change chuck get final product, and integrated first 1 and second 2 do not need replacing, thereby has practiced thrift cost of manufacture; Reduce the time of changing chuck and the time of adjusting lathe, improved production efficiency.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
