Abstract
The invention discloses a respectively adjustable center frame mechanism which comprises a base and a lower support. The lower support is connected onto the base, two roller support arms are connected onto the lower support, a workpiece supporting roller is arranged at an end of each roller support arm, an upper support is connected with the lower support by a rotary shaft, a roller support arm is arranged on the upper support, a workpiece supporting roller is similarly arranged at an end of the roller support arm of the upper support, and the upper support and the lower support form an open frame body of a center frame after the upper support is fastened relative to the lower support. The respectively adjustable center frame mechanism has the advantages that a cutter can directly pass the center frame without being turned around or secondarily clamped during machining, accordingly, time and labor can be saved, and the work efficiency can be improved; workers can adjust the roller support arms 6 by means of turning hand wheels 4, the three roller support arms can be respectively adjusted, so that the three rollers can be assuredly simultaneously supported on a workpiece, the respectively adjustable center frame mechanism is good in workpiece stress bending control effect, and the machining precision can be improved.
Description
Technical field
The present invention relates to a kind of central frame mechanism, particularly a kind ofly distinguish adjustment type central frame mechanism, for processing the lathe of machining long workpieces, the middle part of workpiece is supported, to control machining long workpieces, adding stressed bending in man-hour.
Background technology
Existing lathe centre frame, comprises the base being connected with lathe bed, and there is the support body of centre frame base top, and this support body is circular, and the roller supporting arm of simultaneously adjusting at San Gekexiang center is installed, and in the inner termination of roller supporting arm, roller is housed.During processing machining long workpieces, central frame mechanism is fixed on bed piece guide rail middle part, and workpiece is through centre frame, and by three roller supportings on centre frame, it is crooked that control workpiece adds stressed generation in man-hour.The centre frame of this structure, because frame is originally annular, cannot pass through centre frame when cutter moves along guide rail, and obstructed disposable processing need to be reversed end for end workpiece secondary clamping, wastes time and energy, and machining accuracy is also had to impact; Three rollers are adjusted simultaneously, and the error owing to installing, easily occurs that three rollers can not support to place simultaneously, control the weak effect of workpiece bending.
Summary of the invention
The object of this invention is to provide a kind of simple in structure, cutter and can be smoothly by centre frame, without tune secondary clamping, while improving machining accuracy, time saving and energy saving, roller supporting workpiece, can establish respectively wholely to guarantee the being supported on adjustment type the distinguished central frame mechanism on workpiece simultaneously, overcome the deficiencies in the prior art.
Of the present inventionly distinguish adjustment type central frame mechanism, comprise base and be connected to the lower carriage on base, on lower carriage, be connected with two roller supporting arms, the roller of supporting workpiece is all equipped with in the termination of each roller supporting arm, described lower carriage is connected with upper bracket by rotating shaft, on upper bracket, be also provided with a roller supporting arm, the termination of this roller supporting arm is equipped with the roller of supporting workpiece equally, upper bracket with respect to lower carriage fasten fastening after with the open support body of lower carriage formation centre frame.
Described roller supporting arm is located in the hole on lower carriage and upper bracket, and the centre bore of roller supporting arm has internal thread and is furnished with screw mandrel, and the external end head of screw mandrel is by gland axial limiting, and gland is fixed on lower carriage and upper bracket, and the external end head of screw mandrel is connected to handwheel; The inner termination of roller supporting arm is fixed with support plate by end cap, and described roller is arranged on support plate by wheel shaft.
Of the present inventionly distinguish adjustment type central frame mechanism, because center support body is not circular, be Open architecture, adding man-hour cutter can be directly by centre frame place, without tune secondary clamping, time saving and energy saving, has improved operating efficiency; Three roller supporting arms can be adjusted respectively, guarantee that three rollers are supported on workpiece simultaneously, control the stressed bending effect of workpiece good, have improved machining accuracy.
Accompanying drawing explanation
Fig. 1 is the structural representation of the specific embodiment of the invention;
Fig. 2 is the partial schematic sectional view at the roller supporting arm place shown in Fig. 1.
The specific embodiment
As shown in Figure 1: 10 is base, and base 10 is connected with the guide rail of lathe.Base 10 is connected with lower carriage 1.On lower carriage 1, be connected with two roller supporting arms 6, the roller 9 of supporting workpiece is all equipped with in the termination of each roller supporting arm 6.Lower carriage 1 is connected with upper bracket 3 by rotating shaft 2, and upper bracket 3 can rotate with respect to lower carriage 1.On upper bracket 3, be also provided with a roller supporting arm 6, the termination of this roller supporting arm 6 is equipped with the roller 9 of supporting workpiece equally, upper bracket 3 with respect to lower carriage 1 fasten fastening after with the open support body of lower carriage 1 formation centre frame, be center support body semicircular in shape, rather than annular of the prior art.
As shown in Figure 2: above-mentioned roller supporting arm 6 is located in the hole on upper bracket 3, the centre bore of roller supporting arm 6 has internal thread and is furnished with screw mandrel 11, the external end head of screw mandrel 11 is by gland 12 axial limitings, gland 12 is fixed by screws on upper bracket 3, the external end head of screw mandrel 11 is fixedly connected with handwheel 4, rotates handwheel 4 and can drive roller supporting arm 6 to move.At upper bracket 3 upper sides, be provided with jackscrew 5, for the roller supporting arm 6 to inner side, lean spacing.The inner termination of roller supporting arm 6 is fixed with end cap 13, by end cap 13, is fixed with two parallel support plates 7, and roller 9 is arranged on support plate 7 by wheel shaft 8.
Two roller supporting arms 6 on lower carriage 1 are identical with said structure, now do not describe in detail.
This mechanism, because center support body is not circular, is Open architecture, and adding man-hour cutter can be directly by centre frame place, without tune secondary clamping, time saving and energy saving, has improved operating efficiency; Rotate handwheel 4 capable of regulating roller supporting arms 6, and can adjust respectively three roller supporting arms, guarantee that three rollers are supported on workpiece simultaneously, control the stressed bending effect of workpiece good, improved machining accuracy.
