Abstract
Disclosed is a tool clamp for machining a vertical type crankcase. The two sides of a base are fixedly connected with a left supporting plate and a right supporting plate through fastening threaded rods, a cross beam is arranged at the upper end of the left supporting plate and the upper end of the right supporting plate, and the cross beam is fastened at the upper end of the left supporting plate and the upper end of the right supporting plate through fixing threaded rods. A compressing threaded rod is arranged in the middle part of the cross beam, and the vertical type crankcase is compressed on the base through the compressing threaded rod. In the using process, the vertical type crankcase is placed on a datum plate of the base first, positioning threaded rods and positioning locking threaded rods on the left supporting plate and the right supporting plate are used for enabling the vertical type crankcase to be positioned on the datum plate of the base, and then the compressing threaded rod is used for enabling the vertical type crankcase to be compressed on the datum plate of the base. According to the tool clamp for machining the vertical type crankcase, clamping is very convenient, floating plates do not need to be taken up and down along with workpieces as before, in the compressing process, only one compressing bolt is needed, adjusting is made to be quite convenient through the datum plate every time, as long as the datum plate is adjusted, the requirements for workpiece center distances and the depth of parallelism of the planes and inner holes of the workpieces can be met, and thus production efficiency is greatly improved.
Description
Technical field
The utility model belongs to technical field of tooling clamps, specifically relates to a kind of for processing the frock clamp of vertical type crankcase.
Background technology
In prior art, be to be provided with a compressing support plate on bedplate for the frock clamp original structure of processing the vertical type crankcase, compress by front and back two bolts, while pressing the front bolt, make base stressed, compressing support plate itself is also stressed simultaneously, forms tension force, but due to the rigidity deficiency, two boards all outwards opens, and this product depth of parallelism requires in 0.08, so while pressing the front bolt, one dial gauge can only be set on bedplate, efficiency is very low.Enterprise product has a large amount in variety usually now, so frock can often be changed, careless slightlyly all can fall the basic skill or training and fill precision, during each the replacing, centre-to-centre spacing and the depth of parallelism of workpiece all need to reach requirement, during debugging, be difficult to two kinds of requirements are reached simultaneously, therefore each adjustment is all needed a day or two the time, and efficiency is very low.
Summary of the invention
The utility model is mainly to solve the existing technical problem of above-mentioned prior art, provides a kind of for processing the frock clamp of vertical type crankcase.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of for processing the frock clamp of vertical type crankcase, comprise base, described base both sides are fixed with left and right two stands plate through fastening screw, the upper end of left and right two stands plate is provided with crossbeam, crossbeam is fastened on the upper end of left and right two stands plate through standing screw, the middle part of crossbeam is provided with clamping screw, via clamping screw, the vertical type crankcase is pressed on base.
As preferably, on described base, middle part is provided with datum plate, and the vertical type crankcase is pressed on the datum plate of base.
As preferably, be hung with pressing plate between described crossbeam and vertical type crankcase, pressing plate is arranged on crossbeam through the unsteady screw rod of pressing plate, the unsteady screw rod of pressing plate is provided with spring, when clamping screw is pressed on base via pressing plate by the vertical type crankcase, spring on the unsteady screw rod of pressing plate is compressed, and when clamping screw resets, the unsteady screw rod of recoil of spring band dynamic pressure plate and pressing plate also reset.
During use, first the vertical type crankcase is seated on the datum plate of base, use positioning screw and positioning and locking screw rod on the two stands plate of left and right the vertical type crankcase to be positioned on the datum plate of base, then via clamping screw, the vertical type crankcase is pressed on the datum plate of base.The utility model is a kind of for processing the frock clamp of vertical type crankcase, milled before this dark 10mm in the middle of base, put herein a datum plate, set up into left and right two stands plate on base, connect a crossbeam on the two stands plate of left and right, connect pressing plate with the unsteady screw rod of pressing plate, the unsteady screw rod of pressing plate is provided with spring, through these behaves, make clamping very convenient, float plate is without taking up and down together with workpiece like before, as long as unclamp hold-down bolt, at the elastic force effect lower platen of spring, can automatically leave workpiece; And while compressing as long as a hold-down bolt, when being stressed because of base, crossbeam itself is also stressed, and this power is passed base back by left and right two stands plate, base is had to pulling force upwards, pressure and pulling force are cancelled out each other, and base can outwards not open again, just not be used in while compressing and have used dial gauge.Put a datum plate in the middle of base, effect is to make each mode very convenient, after frock and lathe flange connect, as long as adjust the requirement that datum plate just can meet workpiece centre distance and workpiece planarization and the endoporus depth of parallelism, very simple, original debugging needs the workshop technical staff, and the operative employee also can adjust voluntarily now, has greatly improved production efficiency.Therefore, the utlity model has the characteristics such as simple in structure, reasonable in design.
The accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: referring to Fig. 1, base of the present utility model 1 both sides are fixed with left and right two stands plate 3 through fastening screw 13, the upper end of left and right two stands plate 3 is provided with crossbeam 6, crossbeam 6 is fastened on the upper end of left and right two stands plate 3 through standing screw 7, the middle part of crossbeam 6 is provided with clamping screw 10, via clamping screw 10, vertical type crankcase 4 is pressed on base 1, on base 1, middle part is provided with datum plate 2, and vertical type crankcase 4 is pressed on the datum plate 2 of base 1.Be hung with pressing plate 5 between crossbeam 6 and vertical type crankcase 4, pressing plate 5 is arranged on crossbeam 6 through the unsteady screw rod 8 of pressing plate, the unsteady screw rod 8 of pressing plate is provided with spring 9, when clamping screw 10 is pressed on base 1 via pressing plate 5 by vertical type crankcase 4, spring 9 on the unsteady screw rod 8 of pressing plate is compressed, when clamping screw 10 resets, the unsteady screw rod 8 of spring 9 resilience band dynamic pressure plates and pressing plate 5 also reset.
