Abstract
The invention relates to a carrier roller mechanism for a horizontal lathe. The carrier roller mechanism is provided with a base which is matched with a lathe guide rail, a lead screw which is perpendicular to the longitudinal direction of the guide rail is arranged on the base, and a hand wheel is connected to the front end of the lead screw; brackets are connected on the base in a sliding mode; carrier rollers are arranged on the brackets by wheel shafts; worms are arranged on the brackets in the direction which is parallel to the guide rail; screw nuts are matched with the lead screw, and skewed teeth are machined on the outer surfaces of the screw nuts and are matched with the worms; and the brackets, the wheel shafts, the carrier rollers, the worms and the screw nuts are two groups and are symmetrically arranged above the base, and the two screw nuts which are matched with the lead screw rotate leftwards and rightwards. The carrier roller mechanism is used for supporting more heavy workpieces, so that the workpieces are more stable in the machining process, the self weight of the workpieces and cutting force in the machining process are overcome, and the machining accuracy is ensured.
Description
Technical field
The present invention relates to a kind of carrying roller mechanism, particularly a kind of carrying roller mechanism that is used for horizontal lathe.
Background technology
When utilizing the big workpiece of horizontal lathe processing at present,, also can produce bigger cutting force during cutting because large-scale workpiece is heavier; Frock to workpiece can produce bigger active force, occurs the insecure phenomenon of workpiece sometimes, does not also have corresponding support component can satisfy the rigidity requirement now; In order to address the above problem, must strengthen the clamping mechanism of workpiece, cause the clamping mechanism specification big; It is big, complicated to take up room.
Summary of the invention
The purpose of this invention is to provide a kind of to workpiece to be machined play supporting bracket work, overcome workpiece deadweight and cutting force, assurance clamping workpiece firmly, clamping workpiece mechanism can corresponding simplification the carrying roller mechanism that is used for horizontal lathe, overcome the deficiency of prior art.
The carrying roller mechanism that is used for horizontal lathe of the present invention is provided with the base that matches with the lathe guide rail, and the vertical perpendicular leading screw with guide rail is installed on base, and the front end of leading screw is connected to handwheel;
On base, slidely connect carriage, through wheel shaft carrying roller is installed on the carriage, be parallel to the guide rail direction on the carriage worm screw is installed, be furnished with screw mutually with described leading screw, the outer surface of screw is processed with helical teeth, and this helical teeth and described worm screw match;
Described carriage, wheel shaft, carrying roller, worm screw, screw are two groups, above base, are symmetrical set, and two screws that wherein match with leading screw are divided into left-handed and dextrorotation.
The carrying roller mechanism that is used for horizontal lathe of the present invention, the mode that is slidingly connected between wherein said carriage and the base is for being fixedly connected with slide key on the bottom surface of carriage, and this slide key matches with elongated slot above the base.
The carrying roller mechanism that is used for horizontal lathe of the present invention; Can support workpiece through carrying roller, because the screw that matches with leading screw divides left-handed and dextrorotation, during through the handwheel rotational lead screw; Two screws can be relatively near or leave; The worm screw that matches with screw leans on its self-locking property to drive corresponding carriage and moves, two carriages do thereupon near or the action left, make carrying roller support picking-up to the workpiece of different size.When rotating wherein a worm screw, can drive associated screw and rotate, again through self-locking, screw can only be moved while rotating between screw and the leading screw, drive carriage simultaneously and move, reach the purpose of independent adjustment carriage.This carrying roller mechanism supports heavier workpiece, makes workpiece more stable in process, has overcome the deadweight of workpiece and the cutting force in the process, has guaranteed machining accuracy.
Description of drawings
Fig. 1 is the structural representation of the specific embodiment of the invention;
Fig. 2 is that A-A shown in Figure 1 analyses and observe enlarged diagram.
The specific embodiment
Like Fig. 1, shown in 2: 1 is the guide rail on the body of lathe bed, and 3 is base, and base 3 matches with guide rail 1, and base 3 with respect to guide rail 1 slidably.
Vertical perpendicular leading screw 5 with guide rail 1 is installed on base 3, between the front end of leading screw 5 and the base 3 front end sleeve 11 is housed, bolt is connected between front end sleeve 11 and the base 3.The front end place of leading screw 5 is connected to handwheel 12.Rear end cover 4 is housed between the follower head of leading screw 5 and the base 3.
On base 3, slidely connect carriage 8, through wheel shaft 9 carrying roller 10 is installed on the carriage 8.Be parallel to guide rail 1 direction on the carriage 8 worm screw 7 is installed, the end of worm screw 7 is contained on the carriage 8 through rear axle housing 14, and rear axle housing 14 and carriage 8 are connected through screw.The other end of worm screw 7 is contained on the carriage 8 through front shaft sleeve 15, is connected through bolt between front shaft sleeve 15 and the carriage 8.Be furnished with screw 6 mutually with leading screw 5, the outer surface of screw 6 is processed with helical teeth, and this helical teeth and worm screw 7 match.
Above-mentioned carriage 8, wheel shaft 9, carrying roller 10, worm screw 7, screw 6 are two groups, above base 3, are symmetrical set, and two screws 6 that wherein match with leading screw 5 are divided into left-handed and dextrorotation.During rotational lead screw 5, two screws 6 can do synchronous near or the action left, simultaneously through and worm screw 7 between self-locking performance drive carriage 8 and move with respect to base 3.
The mode that is slidingly connected between carriage 8 and the base 3 is for being fixedly connected with slide key on the bottom surface of carriage 8, this slide key matches with base 3 top elongated slots, utilizes the side cooperation of slide key and elongated slot to lead.
On base 3, be processed with T type groove 16, bolt hole and upper end that the bolt 17 that matches with T type groove 16 is upward through on the carriage 8 are furnished with nut 18.When rotational lead screw 5, when making two carriages arrive correct position, fastening through nut 18.Carriage 8 also can directly utilize T type groove to lead.
During use, workpiece is seated on the carrying roller 10, and carrying roller rotated thereupon when workpiece rotated, and utilizes the distance between two carrying rollers of leading screw 5 adjustment, utilizes worm screw 7 can adjust the position of carriage 8 alone.
