Description
Technical field
The utility model relates to Digit Control Machine Tool, relates in particular to a kind ofly when processing slim type part or the relatively poor part of rigidity, is used to eliminate the lateral support device that cutting force causes part deformation.
Background technology
During the relatively poor part of processing slim part or rigidity, because Tool in Cutting power is bigger, part can't be kept out cutting force and can be bent, and causes part deformation, influences machining accuracy, at this part processing problem, does not also have simple solution at present.
The utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, it is a kind of when processing slim type part or the relatively poor part of rigidity that the utility model provides, and is used to eliminate the lateral support device that cutting force causes part deformation.
Technical scheme: for solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of lateral support device comprises two needle bearings, screw rod, guide rod, spring, movable block, upper body, cylinder and supports; Described cylinder is fixed on the support, and the output shaft of cylinder is connected with the upper body, is connected by trapezoid groove structure between support and the upper body, is connected by trapezoid groove structure between upper body and the movable block; Described movable block is provided with chute, and the stiff end of spring is fixed on the bottom of chute, and the free end of spring is connected with an end of guide rod, and the other end of guide rod is fixed by screw rod and needle bearing; Described upper body is axial vertical along the moving direction of support and part to be processed, the moving direction of guide rod is axial vertical with part to be processed, movable block is along the moving direction of upper body and the axially parallel of part to be processed, and upper body and the adjusted relative position of movable block are fixed by trapezoidal screw.
By regulating the position relation between upper body, support and the movable block, can regulate the position relation between needle bearing and the part to be processed:, can regulate needle bearing and part to be processed distance along the part to be processed vertical direction by regulating the position relation between upper body and the support; By regulating the position relation between movable block and the upper body, can regulate needle bearing and part to be processed distance along the part to be processed parallel direction.
Spacing between two needle bearings can be regulated according to shape, the size of part to be processed, during use, with the workpiece to be machined frame on two needle bearings, part to be processed is subjected to the influence of cutting force that certain motion takes place, and part cutting force passed to needle bearing, impel guide rod to move along the chute on the movable block, because the existence of spring, its compressive force balance the part cutting force of cutter, when part breaks away from needle bearing, guide rod in time resets, for the part cutting force of next cycle balance cutter is prepared.Described cylinder can promote the upper body and move on support, and the size of spring compression stress can be by the Stroke Control of cylinder.
Trapezoid groove structure is all adopted in connection between being connected between support and the upper body, upper body and the movable block, can reduce the contact area between the different parts, makes each parts in that mutual frictional force when mobile takes place is little, and it is more steady to move.
Be provided with suitable pin shaft structure between described guide rod and the movable block, can control the directed of guide rod and location, prevent that guide rod is offset by pin shaft structure.
Be connected with lubricating oil pipe on the described needle bearing, make when the part to be processed high speed rotary cuts, the frictional force between itself and the needle bearing is less, reduces the influence to part to be processed cutting precision and stock-removing efficiency.
Beneficial effect: a kind of lateral support device that the utility model provides, auxiliary support apparatus as machine components processing, the reliability height of its action, adjusting range are big, and this device simple in structure, loading and unloading easy to adjust, can improve the crudy and the machining accuracy of product, be particularly useful for producing in batches.
