Abstract
A kind of bolt jack, relate to a kind of jack, comprise steel ball (1), bolt and base (5), described bolt comprises bolt cap (3), stud (4) and groove (2), bolt cap (3) is provided with in the upper end of stud (4), be provided with groove (2) at the end face of bolt cap (3), described steel ball (1) is arranged in groove (2), is provided with the screw matched with stud (4) at the middle part of base (5); The utility model structure is simple, easy to use, not only meet the feature that in the adjustment process of main equipment or heavy digital control machine tool etc., jack consumption is large, simultaneously easy to adjust, save a large amount of human costs, have positive effect to the quality control, cost control etc. of project.
Description
[technical field]
The utility model relates to a kind of jack, especially relates to a kind of bolt jack.
[background technology]
Known, in the workplatform of equipment and lathe, as in the workplatform of mining equiment and heavy digital control machine tool and the adjustment set up procedure of lathe bed before once grouting, needing first by tentatively adjusting the horizontal accuracy of workplatform, reaching after certain accuracy rating until it and just can carry out once grouting operation; Due to before grouting, adjustment parallels does not bear bearing capacity, therefore the preliminary adjustment by carrying out precision after supporting workplatform or bed piece by other instruments is needed, in traditional mounting and adjusting process, often adopt and use interim adjustment parallels or use inclined sizing block peace parallels two kinds of modes, but when using interim adjustment parallels to adjust, although Adjustment precision is high, contact surface is large, bearing capacity is also larger, because setting range is little, adjustment strength also needs comparatively large, wastes time and energy; When using the parallels adjustment of inclined sizing block peace, although inclined sizing block peace parallels is durable in use, not yielding, Adjustment effect is also comparatively stable, but setting range is less, inclined sizing block is made up of together two pieces of inclined sizing blocks, two to three blocks of plain cushion iron usually, and it is highly usual at 30mm to 50mm, and in adjustment process, friction force is large, platform or lathe bed occurred level direction is easily caused to jump, due to the restriction of locus, inclined sizing block can only carry out unidirectional adjustment, and adjustment is wasted time and energy; Relatively can be found out by excellent, the shortcoming of above-mentioned two kinds of traditional methods of adjustment, traditional method of adjustment inefficiency, large to the blue-collar dependence of workman, setting range is little, therefore select a kind of simple and easy, setting range large and the adjustment mode that Adjustment effect is stable is necessary.
[summary of the invention]
In order to overcome the deficiency in background technology, the utility model discloses a kind of bolt jack, achieve in the mounting and adjusting process of workplatform or bed piece simple and easy, setting range large and the object that Adjustment effect is stable.
In order to realize described goal of the invention, the utility model adopts following technical scheme:
A kind of bolt jack, comprise steel ball, bolt and base, described bolt comprises bolt cap, stud and groove, bolt cap is provided with in the upper end of stud, be provided with groove at the end face of bolt cap, described steel ball is arranged in groove, is provided with the screw matched with stud at the middle part of base.
Described bolt jack, described bolt is self-control bolt.
Described bolt jack, described base is circular or plinth.
Described bolt jack, the material of described base is the round steel of Q235-A.
Described bolt jack, the groove on described steel ball and bolt cap end face is free-running fit.
Owing to have employed technique scheme, the utility model has following beneficial effect:
Bolt jack described in the utility model, by the screw in the middle part of base 5 and self-control being threaded of bolt, the adjustment to regulating object is realized by adjustment self-control bolt screw-in size of screw in the middle part of base 5, simultaneously owing to inlaying the effect of steel ball in the groove 2 of self-control bolt, substantially reduce the friction force in adjustment process, while saving manpower, do not reduce loading strength again; The utility model structure is simple, easy to use, not only meet the feature that in the adjustment process of main equipment or heavy digital control machine tool etc., jack consumption is large, simultaneously easy to adjust, save a large amount of human costs, have positive effect to the quality control, cost control etc. of project.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model using state;
In figure: 1, steel ball; 2, groove; 3, bolt cap; 4, stud; 5, base.
[detailed description of the invention]
By explanation the utility model that the following examples can be detailed, open the purpose of this utility model is intended to protect all technological improvements within the scope of the utility model.
Bolt jack by reference to the accompanying drawings described in 1 and 2, comprise steel ball 1, bolt and base 5, described bolt comprises bolt cap 3, stud 4 and groove 2, bolt cap 3 is provided with in the upper end of stud 4, groove 2 is provided with at the end face of bolt cap 3, described steel ball 1 is arranged in groove 2, is provided with the screw that to match with stud 4 at the middle part of base 5.
Described bolt jack, described bolt is self-control bolt.
Described bolt jack, described base 5 is circular or plinth.
Described bolt jack, the material of described base 5 is the round steel of Q235-A.
Described bolt jack, described steel ball 1 is free-running fit with the groove 2 on bolt cap 3 end face.
Implement bolt jack described in the utility model, be that the round steel of Q235-A forms through machined into manufacture by material by base 5, described bolt is made up through lathe certainly of common 8.8 grades of six-sided head screw bolts, and described steel ball 1 is selected by market according to actual size; The size of described bolt will carry workpiece weight according to it and carry out reasonable selection, and select the size of the steel ball 1 matched with bolt cap 3 groove 2 size, then according to the size of steel ball 1, machine up self-control is carried out to selected bolt, make to be formed between self-control bolt with steel ball 1 suitably to coordinate, finally select the round steel of the Q235-A of suitable diameter, height, assemble after processing the screw thread identical with making bolt thread size by oneself and use; In use, by regulating self-control bolt screw-in size of screw in the middle part of base 5 to realize the adjustment to regulating object.The utility model adjusts at the lathe bed of heavy machine processing department Φ 3.5x20 rice heavy type numerical control sleeping carriage, Φ 2x25 rice heavy type numerical control sleeping carriage, RG300x150/260L-NC heavy-duty numerical control roll grinder, mine factory Φ 2.5x16 rice heavy type numerical control sleeping carriage at present, the adjustment etc. of two metal working FCW150 machining center workplatformes all adopts utility model jack of the present utility model, its result of use is obvious, up to now, above-mentioned lathe has completed the adjustment of lathe bed all, and hand over inspection qualified, completed place in operation, and machine tool accuracy all reaches designing requirement.
The non-detailed portion of the utility model is prior art.
