Description

Vertical revolution tire

Technical field

The utility model relates to a kind of machining mold, is specially a kind of vertical revolution tire.

Background technology

In introducing external electric motor end cap and bearing cap structure, the ventilation inclined hole structure of radiativity is usually arranged.The processing of this kind inclined hole, as shown in Figure 1, 2, be on boring machine, to place general bent plate in the past, configure dedicated positioning disk on the bent plate, then end cap is located, also clamped with the U-shaped pressing plate with seam and positioning disk, the inclined hole axis horizontal is placed, by the revolution of boring machine work tire, make the axis and the boring spindle dead in line of institute's rat holing, carry out inclined hole again and mill brill processing.After having bored first inclined hole, clamping device be unclamped like this, artificial turning of work piece makes second radially inclined hole axis and boring machine dead in line, process again, and the like with all radially inclined hole machine.Operator's labour intensity in workpiece transposition process is increased, and when running into some heavier workpiece, rely on and manually can't finish, also need some auxiliary equipments to cooperate, increased the equipment input, and complicated operation, waste time and energy.

Summary of the invention

The utility model exists labor strength to strengthen, waste time and energy when solving the ventilation inclined hole of existing mold on processing electric motor end cap or bearing cap and problem such as complicated operation, and a kind of vertical revolution mold is provided.

The utility model is to adopt following technical scheme to realize: vertical revolution tire, comprise bent plate and be positioned at bent plate the place ahead and have the positioning disk of seam, the positioning disk outside is fixed with pressing plate by stud, innovative point of the present utility model is that bearing block and bearing are set on the bent plate, the bearing block upper support has can be around the rotating disk of its rotation, spring catch mechanism is set between bearing block and the rotating disk, and the rotating disk outside is fixed with positioning disk.In the said structure, bent plate is put on the boring machine work tire, plays overall supporting role; Bearing block rises and places bearing, supports rotating disk, also plays the function served as bridge that rotating disk is connected with bent plate; Rotating disk can rotate around bearing block, realizes the arbitrarily angled rotation of workpiece then; Positioning disk and rotating disk are fastenedly connected, and play workpiece location, support and clamping action; The effect of spring catch mechanism is automatic and bearing block location after rotating disk and workpiece revolution put in place, mills brill processing so that carry out inclined hole.When workpiece bores the radiation inclined hole, workpiece and positioning disk are felt relieved with seam, compress with pressing plate; The rotation rotating disk make workpiece to be machined first radially the inclined hole axis be horizontal, this moment, rotating disk and bearing block were located with spring catch mechanism, then by revolution, moving forward and backward of lathe bed column and the moving up and down of main spindle box of boring machine work tire, make boring spindle and inclined hole axis coaxle radially, realize the processing in first hole; The trip spring pin mechanism rotates rotating disk then, and second inclined hole axis of workpiece is horizontal, and spring catch mechanism locatees automatically, carries out the processing in second hole.Carry out successively, finish porose processing.

Described spring catch mechanism role can adopt multiple version to realize, spring catch described in the utility model mechanism comprise be arranged on the bearing block edge and with workpiece on ventilation inclined hole position locating hole one to one, also comprise and be arranged on the rotating disk and latch relative and plug housing with position of positioning hole, spring is set on the latch, the latch front end is the chamfering shape, when being convenient to the latch front end and being right against locating hole, automatically in the patchhole, the rear end is fixed with the latch cap, is convenient to manually-operated; When workpiece rotates to inclined hole axis to be processed and boring spindle when being horizontal with rotating disk, latch inserts under the effect of spring in the locating hole on the bearing block automatically, plays positioning action.

In order to make workpiece in process, have good stable, the brill machining accuracy is milled in assurance, between described rotating disk and the bearing block retaining mechanism is set, this retaining mechanism also can adopt multiple version to realize, two tommyhead bolts that retaining mechanism described in the utility model comprises the T-slot that is arranged on the bearing block border and is arranged on the rotating disk and cooperatively interacts with T-slot, the tommyhead bolt end is fixed with rotary handle, two tommyhead bolt positions are relative, rotating disk turns round with tommyhead bolt, its lower end T shape structure is slided along the T-slot on the bearing block, can lock at an arbitrary position.

Compared with prior art, the utility model has adopted bearing revolving structure, spring catch mechanism and retaining mechanism, make workpiece be under the clamped condition, allow positioning disk and workpiece realize machinery rotation easily, so not only reduced working strength of workers, simple to operate, shorten the production cycle, increase economic benefit, and its structural stability is better, is suitable for the processing of general precision inclined hole, can also carry out the Milling Process of skewed slot and the tiltedly tapping processing of screw thread.

The specific embodiment

Vertical revolution tire, as Fig. 3, shown in 4, comprise bent plate 1 and be positioned at bent plate 1 the place ahead and have the positioning disk 2 of seam, positioning disk 2 outsides are fixed with pressing plate 4 by stud 3, bearing block 5 and bearing 6 are set on the bent plate 1, bearing block 5 upper supports have can be around the rotating disk 7 of its rotation, between bearing block 5 and the rotating disk 7 spring catch mechanism is set, as shown in Figure 6, spring catch mechanism comprise be arranged on bearing block 5 edges and with workpiece on ventilation inclined hole 8 positions locating hole 9 one to one, also comprise and be arranged on the rotating disk 7 and latch 10 and the plug housing 11 relative with locating hole 9 positions, spring 12 is set on the latch 10, latch 10 front ends are the chamfering shape, and the rear end is fixed with latch cap 13; Rotating disk 7 outsides and positioning disk 2 are fixing; Between rotating disk 7 and the bearing block 5 retaining mechanism is set also, as shown in Figure 5, two tommyhead bolts 15 that retaining mechanism comprises the T-slot 14 that is arranged on bearing block 5 borders and is arranged on the rotating disk 7 and cooperatively interacts with T-slot 14, it is relative that tommyhead bolt 15 ends are fixed with 16, two tommyhead bolt 15 positions of rotary handle.

When workpiece bores radially inclined hole; in advance this mold is put on the boring table also fastening with screw; clamping workpiece and adjust mold by the following method: workpiece and positioning disk are felt relieved with seam; first radiation inclined hole axis is horizontal; take advantage of a situation and insert in the corresponding locating hole in the latch end of spring catch mechanism at this moment; make rotating disk and bearing block fix; the rotary handle of circumvolve lock set kit then; make tommyhead bolt front end and T-slot tightly lock, so just guarantee that rotating disk and bearing block are fixed together more closely.After above-mentioned parts adjust, by revolution, moving forward and backward of lathe bed column and the moving up and down of main spindle box of boring machine work tire, make boring spindle and inclined hole axis coaxle radially, realize the processing in first hole.The rotary handle of circumvolve lock set kit then, retaining mechanism is loosened, extract the latch of spring catch mechanism again, rotate rotating disk, the workpiece second radiation inclined hole axis is horizontal, and latch is taken advantage of a situation and is inserted automatically in the locating hole of bearing block under the effect of spring force, once more the location, and tighten locking device, can carry out the processing in second hole.Finish successively porose processing.
