Abstract

The utility model discloses a grinding head which can be matched with various machine tools and is used for grinding processing. The grinding head contains a grinding head body having a sand wheel, an electric motor and a base which can be connected with other machine tools. The grinding head works by matching with a lathe, a milling machine and a planing machine, etc. The grinding head can make the processing on an inner cylindrical surface, an outer cylindrical surface, a conical surface, a screw thread, a worm screw or a flat surface, etc. The grinding head overcomes the defects that the traditional grinding head can be used only by matching with the grinding machine, the function is single and the adaptation range is narrow; the grinding head has the advantages that it can be used by matching with various machines, the working range is wide, the adaptability is strong, and the equipment investment is saved, and is especially adapted to be used for the small-lot or the single-piece grinding processing in the small factory.

Description

A kind ofly be used for mach bistrique

The utility model belongs to a kind of accurately machined abrasive machine that is used for, particularly a kind of can with the matching used bistrique of multiple lathe.This bistrique can be supporting and be used for grinding with lathe, milling machine, planer etc.

In machining apparatus, the bistrique of general mill celebrating all with grinding machine such as supporting use such as peripheral milling, flat stone mill accordingly, and can not with other such as supporting uses such as lathe, milling machine, planers.Equally, processing such as the latter also can only carry out corresponding car, mills, plane, and can not carry out grinding.Yet grinding be again most of accurately machined must be through operation, in order to satisfy accurately machined requirement, machining factory just must be equipped with corresponding grinding machine, or takes the mode of cooperation processing to solve.The former invests greatly, and usage ratio of equipment is often also lower, and is special extremely uneconomical for general little factory and maintenance department; And take cooperation processing, then not only prolong the production cycle, but also can increase production cost.Therefore, conventional bistrique since can only with the supporting use of corresponding grinding machine, can not carry out grinding and have adaptability, defectives such as the scope of application is narrow, function singleness with other machining tool is supporting.

The purpose of this utility model be design a kind of can with the matching used bistrique of multiple lathe, enlarging the bistrique scope of application, and reach simultaneously and make conventional lathe, milling machine, planer etc. increase the grinding function, realize purposes such as a tractor serves several purposes.

Solution of the present utility model is that bistrique main body, the motor of drive bistrique work and the base designs that is connected with lathe are integral; Bistrique main body and motor all are fixed on the base, and whole bistrique then is connected also cooperating with it by base with supporting lathe.Therefore, this bistrique comprises the bistrique main body, motor and control box thereof; Key is also to comprise the base that can be connected with other lathe; The bistrique main body then comprises husky wheel, husky wheel main shaft, collar bush and lifting and angular adjustment frame, and this adjusting bracket is connected with base by coattail board and lifting screw; Motor then is connected with base by bearing support; Whole device then by the clamping screw on the base or/and centre bore and supporting lathe link into an integrated entity.For adapt to the bistrique main body because of lifting or/and the change in location that angle adjustment produced, between motor bearing frame and base, also be provided with two cover dovetail and dovetail grooves in length and breadth, and between bearing support and lifting coattail board, also be symmetrical arranged two adjustable spring screw rods, with the distance between adjusting and the husky wheel of maintenance; Between motor base and support, establish simultaneously a rotating fixed head to regulate the angle of motor (husky wheel), make two axis remain on same plan-position, thereby guarantee the formedness that belt contacts with two husky wheels.In order to adapt to the requirement of inner hole grinding, big (master), little (from) ratio of belt pulley is advisable with 1: 4～4.5.The motor of this bistrique adopts stepless speed regulation; Control box is provided with switch, forward and backward button and stepless speed regulation knob.

The utility model can be connected the also base of interoperation with multiple lathe owing to being provided with, thereby can make supporting with it lathe increase grinding function; The bistrique main body is provided with lifting and angle adjusting mechanism, both can grind inside and outside circle in being used with lathe etc., but grinding core hole (face) and screw thread, worm screw etc. again also can cooperate flat surface grinding etc. with milling machine, planer.Therefore, the utlity model has can with the supporting use of multiple lathe, and the range of work is wide, adaptability is strong, save equipment investment, can reduce advantages such as unit price and small lot grinding cost.

Embodiment

Present embodiment motor 9. adopts 2800 rev/mins of 2 grades of motor, rotating speeds, 0.5kw; Establish 13, two forward and backward buttons 14. of a power switch and a stepless speed regulation knob 15 on the control box 12.Main shaft 35. materials in the bistrique main body are 9CrSi, long 300mm, and stage casing diameter phi 28mm, two ends axle journal (with holding the cooperation place) is φ 25mm, and heat treatment hardness is HRC48～55 °; 36205 type angular contact ball bearings of two dish C level precision are respectively adopted in front and back; Collar bush 25, material are HT21-40, external diameter φ 84mm footpath, internal diameter φ 52mm, long 204mm; 4 springs 31 all are set, and cover 29. is fixing with collar bush 25. by alignment pin 30 in the fore bearing between forward and backward bearing inner sleeve 29 and 32.Collar bush 25 adopts clamping screw 2 and 23. to fix then by round boss on the angle adjustment plate 23 and the groove fit on the lifting dovetail 4 again, and the upper and lower motion with the rotation of lifting screw 5; Collar bush 25 also can rotate by the concave station of the boss on the angle adjustment plate 23 on coattail board 4 and regulate its angle simultaneously; The front of angle adjustment plate 23. is provided with angle index.Motor fixed head 10. can rotate with respect to bearing support, so as with the rotational synchronization of collar bush 25., thereby guarantee that two belt pulley axis reach good contact the between two belt pulleys and the belt at grade.Two adjustable spring screw rod 21. symmetries are connected between motor bearing support 7. and the lifting coattail board 4., mainly play the tension force effect, guarantee the pressure that contacts between belt 6 and two belt pulleys, when sand wheel 1. is done elevating movement, drive simultaneously motor bearing frame 7. longitudinally dovetail groove 16 seesaw, constant with the distance of keeping between two husky the wheels.The bottom of base 20 and each lathe connecting portion are ∏ type cell body, be that left and right both sides (is that the front is seen with side view 2.) respectively have a gulde edge, on each gulde edge, set up 2～3 clamping screws separately, do side direction locking, and establish a centre bore 37. in order to the vertical location of bistrique in the central upper portion of cell body.

When this bistrique and lathe are used, at first lathe saddle is screwed off, at the cushion about thick 2mm of pad on the knife rest, again the centre bore on the bistrique base 37. is loaded on the tool rest over against the screw rod on the carriage saddle, be fixed by the flat bed side and by clamping screw 18, utilize the screw rod on cushion block, nut and the tool rest that vertical the fixing of bistrique can be used again.Utilize the transmission mechanism of lathe, this bistrique both can be internally, external cylindrical surface, the conical surface carry out grinding, can process deep hole, screw thread etc. again.If the cooling fluid that former lathe adopted is an emulsion, then can be directly used in the grinding cooling; If what adopt is that fluid then can be in addition connect with one and coils and emulsion etc. cools off.

This bistrique if with milling machine, the supporting use of planer, then this bistrique can be loaded on lathe bed etc. by a coattail board and go up work.
