Description

Semi-automatic multi-angle universal fixturing

Technical field

The utility model relates to a kind of mechanical universal fixturing, particularly a kind of semi-automatic multi-angle universal fixturing.

Background technology

The universal anchor clamps are meant the mechanical clamp of the workpiece that can be used to process various sizes and shape within the specific limits, and in all kinds of anchor clamps, its range of application is the widest.For example scroll chuck, mechanical universal fixturing, rotary table, omnipotent calibration and magnetic worktable all belong to the universal anchor clamps.Universal fixturing can shorten service working time aborning, raise labour productivity, and guarantees the machining accuracy of workpiece, stabilized product quality.At present, the universal fixturing that enterprise is used, mainly be the manual lead screw universal fixturing, there is many shortcomings: low as efficient, easily cause error, clamping force is little, chip removal is poor, slow motion, structure is not compact and inapplicable and high-rate cutting, labor strength power, the scope of application are little, require part shape and the processed position must rule etc.More than be the defective that universal fixturing exists always, and also do not find the Perfected process that addresses these problems always.

Summary of the invention

Technical problem to be solved in the utility model is the defective that exists at existing product, provides a kind of semi-automatic multi-angle universal fixturing, to remedy the deficiency of existing product.

The technical solution of the utility model is achieved in that it comprises clamp body, clamping part and base, is characterized in that: be fixed with ball seat on the clamp body, ball seat is provided with ball-and-socket, and the clamping part bottom is provided with and the corresponding ball stud of ball-and-socket.Clamp body is movably connected on the base; Base is divided into upper bed-plate and lower bottom base, be respectively equipped with top rotary table and lower rotary table on upper bed-plate and the lower bottom base, have groove in the middle of top rotary table and the lower rotary table, top rotary table and lower rotary table snap together, a turning cylinder is equipped with in the bottom activity of clamp body, and the turning cylinder activity is contained in the cavity of upper and lower rotating disk medial launder formation; Upper bed-plate and lower bottom base are fixed by screw; The front end of clamping part is provided with lead angle.

The utlity model has favorable rigidity, clamp action fast, clamp that the accessory size scope is big, compact conformation, volume is little, self-locking performance good, interchangeable jaw, manual and motor-driven two kinds of modes of operation, be applicable to operation cuttings such as the milling of various irregular parts position, brill, plane, can in the space, rotate arbitrarily, enlarged the processing range of lathe greatly, solve big stroke fast moving and the big clamping force contradiction between moving at a slow speed, improved efficient and energy-conservation.

The specific embodiment

As shown in Figure 1 and Figure 2, the utility model comprises clamp body, clamping part and base, is fixed with ball seat 2 on the clamp body 1, and ball seat 2 is provided with ball-and-socket 3, and clamping part 4 bottoms are provided with and ball-and-socket 3 corresponding ball studs 14, and clamp body 1 is movably connected on the base; Base is divided into upper bed-plate 5 and lower bottom base 6, be respectively equipped with top rotary table 7 and lower rotary table 8 on upper bed-plate 5 and the lower bottom base 6, have groove 9 and 10 in the middle of top rotary table 7 and the lower rotary table 8, top rotary table 7 and lower rotary table 8 snap together, a turning cylinder 11 is equipped with in the bottom activity of clamp body 1, and turning cylinder 11 activities are contained in the guide-track groove of upper and lower rotating disk medial launder formation; Upper bed-plate 5 and lower bottom base 6 are fixing by four screws 12; The front end of clamping part 4 is provided with lead angle 13.

Clamping part of the present utility model can be hydraulic clamp parts shown in Figure 1, also can be mechanical grip parts shown in Figure 3.

Operation principle and process:

When regulating idle stroke, clamping part upwards can be mentioned, be the center with 15 (see figure 4)s of shipping and reselling on another market, clamping part 4 moves up, and ball stud 14 leaves ball-and-socket 3.At this moment, can regulate moving jaw iron position forward or backward, when moving to desired location, clamping part 4 be put down again, ball stud 14 enters ball-and-socket 3.At this moment, clamping part 4 can not move backward, can bear clamping force.After finished the location originally, can adopt machinery and two kinds of clamping modes of hydraulic pressure so that moving jaw iron clamps part.Space rotation arbitrarily is that rail plate groove and rotating shaft are arranged in the plane, can make the position that rotation is flexible more, be more prone to find suitable processing like this.Reduce working strength of workers greatly.

Base is that two concentric columns are formed upper bed-plate and lower bottom base, and the circle slip guide-track groove of a level is set in the concentric column.Rotating disk is rotatable 360 degree in circle slip guide-track groove, connect the universal fixturing body component on the rotating disk shaft, and rotating shaft can make universal fixturing clamp body parts revolve in vertical direction and turn 90 degrees (see figure 1).

For reaching the braking purpose, we use the concentric column base to be divided into upper and lower two-section, are fixed by equally distributed four screws of concentric column upper surface, so that the two-section concentric column does not separate, also make circular rail plate relative fixed.The rotating disk periphery is a hemispherical, so that increase contact area to bear higher impact force.Rotating disk is divided into two halves up and down, and two parts leave a slit.When being adjusted to desired location, be wrenched screw, make cylinder up and down two bodies close tightly, circular slip guide clearance diminishes.Simultaneously, rotating disk two parts also close tightly.At this moment, rotating shaft is subjected to very big friction, and rotating shaft all can not be rotated in level and vertical direction, thereby reaches fixing purpose.This braking technology breaks through traditional wire contact mode of braking, adopts the face way of contact, increases contact area greatly, makes the rigidity of semi-automatic multi-angle universal fixturing better.(seeing Fig. 1 and Fig. 6 for details)

Adopt after the utility model, can save crossed process, reduce the non-cutting time of workpiece location and centering, some the location clamping time that can use anchor clamps (as this hydraulic drive) is need several seconds only, like this, just the spoke degree ground shortening time raises labour productivity greatly.

Adopt after the utility model, the location of workpiece is guaranteed by universal fixturing, not only is much higher than the quality that the line centering can reach, and some workpiece as not adopting special-purpose universal fixturing, just is difficult to even can't processes.

For example after lathe adopted the special boring anchor clamps, just the operation of carrying out boring at lathe one had enlarged the lathe scope of application.

Can save complicated operations such as centering is installed after adopting the utility model, reduce workman's specification requirement.And for example adopted the hydraulic drive anchor clamps of force-increasing mechanism are arranged after, can alleviate workman's labor intensity greatly.
