Abstract

The utility model relates to a die, in particular to a multiple-hole die for the motor case. One end of a flat plate is provided with a vertical drilling jig arranged with a mandrel, and a movable clamp plate is parallel with the drilling jig. The utility model has the advantages of reasonable structure, complex structure and high cost. The multi-clamping does not influence the position accuracy of the drill holes because of a plurality of drill holes.

Description

The porous drill jig

Technical field

The utility model relates to a kind of moulds of industrial equipment, especially relates to a kind of porous drill jig of motor case.

Background technology

At present, the drill jig of holing on the motor casing has multiple, because the plane at boring place has a plurality ofly on the motor casing, the anchor clamps of finishing all boring work of a motor casing can not disposablely clamp and finish, be easy to generate error and clamp motor casing behind hole of every brill again, accuracy descends.A kind of multi-angle drill jig by name (patent No. CN01247032.5), comprise soleplate and cover plate, be provided with many row's small bores by sub-multiple angle or different angle along radial direction on the soleplate, this method has solved the precision of a plurality of holes processing to a certain extent, but the clamp structure complexity, and do not possess boring function on cambered surface.

Summary of the invention

The utility model mainly is at the existing in prior technology complex structure, and the technical problem that processing cost is high provides a kind of rational in infrastructure, the porous drill jig that processing cost is lower.

The utility model is also few at the disposable drilling hole amount of existing in prior technology simultaneously, repeatedly clamps the technical problem of the positional precision etc. of influence boring, provides a kind of drilling hole amount many, repeatedly clamps the porous drill jig of the positional precision that does not influence boring.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a dull and stereotyped end is provided with orthogonal with it limit drill jig, and the limit drill jig is provided with mandrel, and movable pressing board and limit drill jig are parallel to each other.The limit drill jig guarantees that as the main stationary fixture of motor casing it is with dull and stereotyped vertical mutually; The mandrel that is provided with is as bracing frame, fillet drill jig and movable pressing board, thus constituting a complete stationary fixture, mandrel can also bear certain boring cutting force.

As preferably, mandrel sub-support section and cooperate section, the supporting section diameter cooperates the section diameter between 10mm-20mm between 25mm-40mm.Supporting section mainly bears machining power, and diameter cooperates the section diameter more slightly; The cooperation section cooperates with the limit drill jig and interfixes, and its diameter is slightly thin.

As preferably, the end of mandrel supporting section has escape, and mandrel cooperates the end of section to be provided with screw thread and is connected with the nut thread that has handle, and the screw thread termination is provided with key, and the mandrel cooperation section is with spring.The escape of mandrel supporting section end cooperates with the pin clamp on the movable pressing board, and the nut of regulating handle is regulated, and can increase or reduce the horizontal range of limit drill jig and movable pressing board by screw thread, to be fit to the different big or small shells of keeping thinking about; The phenomenon that mandrel cooperates the key on the section to stop mandrel arbitrarily to rotate in the hole of limit drill jig; Spring one end heads on the inwall of limit drill jig, and the other end heads on the shaft shoulder of mandrel, by the interaction of spring and nut, makes mandrel and limit drill jig steadily fixing.

As preferably, the limit drill jig is surrounded by bottom surface and wall, and bottom center has through hole, and through-hole wall is provided with keyway.The inner chamber that the limit drill jig surrounds can make an end of motor casing stretch into, better fixed electrical machinery shell, and the through hole of offering interfixes with it after mandrel is passed, and keyway has prevented the rotation of mandrel after stressed.

As preferably, have screwed hole on the wall of limit drill jig, screwed hole is the center of circle with the center of bottom surface, is evenly distributed on the wall of limit drill jig, screwed hole points to the center of wall.Form fixing angle between the equally distributed screwed hole, in order to ensure the accuracy of bore position on motor casing, equally distributed screwed hole is corresponding with the screwed hole on the motor casing on the drill jig of limit, uses bolting before the boring, by rotation, the multiple batches of pore size distribution of being bored on the motor casing is even.

As preferably, movable pressing board has pin clamp, and deeply to the center of movable pressing board, the pin clamp width is less than mandrel supporting section diameter 2mm-5mm, greater than the diameter 0.5mm-2mm that has the escape place from the edge of movable pressing board for pin clamp.Movable pressing board is as the other end immobilising device of drilling jig gripper, and pin clamp matches with escape on the mandrel supporting section, forms the anchor clamps of adjustable length with the limit drill jig.

Therefore, the utlity model has characteristics such as rational in infrastructure, complex structure, processing cost height, especially is that drilling hole amount is many, repeatedly clamps the positional precision that does not influence boring.

The specific embodiment

Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.

Embodiment 1: adopt steel to make mandrel 3, the diameter of getting mandrel cooperation section 32 is 20mm, cooperates the end car of section 32 that screw thread is arranged at mandrel, is provided with key 6 at the screw thread termination; The diameter of getting mandrel supporting section 31 is 30mm, forms the shaft shoulder between two sections, and car has escape 4 in the end of mandrel supporting section 31, and the diameter at escape 4 places is 24mm (as shown in Figure 1).

Adopt steel to make limit drill jig 2, the through hole that to open a diameter at 21 centers, bottom surface of limit drill jig be 20mm is offered keyway on through-hole wall, be the center of circle with the center of limit drill jig 2, with the circumference trisection, on the wall 22 of limit drill jig, offer screwed hole 8 (as shown in figs. 1 and 3) by the position of trisection.

Adopt steel to make movable pressing board 9, the circular hole that to offer a diameter at the center of movable pressing board 9 be 25mm, and go out width and the big or small identical pin clamp 91 (as shown in Figure 4) of Circularhole diameter from the center to edge cuts.

During use, limit drill jig 2 and dull and stereotyped vertical connection of 1 screw thread are inserted in mandrel to spring 7 and cooperate section 32, cooperate section 32 to pass the through hole of drill jig bottom surface, limit mandrel, and key 6 inserts in the keyway, trace compression spring 7; The nut 5 that has handle is screwed into mandrel cooperates on the screw thread of section 32 ends, up to fitting with the bottom surface 21 of limit drill jig; Motor casing is vertically put into the inner chamber of limit drill jig 2, and mandrel 3 passes motor casing inside; Motor casing and limit drill jig 2 are interfixed by screwed hole 8 with bolt, the movable pressing board 9 of the other end is near motor casing, its pin clamp 91 and escape 4 tablings; After processing one group of hole, motor casing can be rotated to an angle, with bolt motor casing and limit drill jig 2 be interfixed once more, carry out the processing in second batch of hole.
