Abstract
The utility model discloses a numerically controlled processing machine tool for electrode screw thread chasing tools. One end of the bed of the machine tool is provided with a spindle box and a chuck, and a workpiece bracket and tool carriages for installing a cutting tool are installed on guide rail of the bed. The utility model is characterized in that the cutting tool uses a chasing tool driven by a power head; a chasing tool box is directly arranged on a middle tool carriage; a big and the middle tool carriages are respectively driven by a longitudinal and a transversal actuating motors through lead screws; the actuating motors are controlled by a computer control circuit. The utility model has the advantages of high performance price ratio, simple operation, wide range of application, high processing precision, etc. and is welcomed by the domestic steel industry and third world countries with shortage of funds.
Description
The utility model relates to a kind of machining lathe, especially a kind of architecture advances of electrode thread chasing tool machining tool.
Graphite electrode is the important consumable material of steel industry, is in great demand.At present, known electrode thread machining tool is generally formed by the single cutter milling.Large, medium and small three layers of planker of mounting cutter are respectively applied for coarse positioning, the fine positioning when realizing feed, and the feed campaign.Its shortcoming is that trouble, low, the location inaccuracy of efficient are adjusted in operation, and because the omnidistance cutter of machining screw weares and teares easily, and it is big therefore to process pitch error, chamfering is lack of standardization, can't produce high-quality electrode.
The purpose of this utility model is: at the shortcoming of above-mentioned existing electrode thread machining tool, a kind of machining accuracy height is proposed, and numerical control electrode chaser machining tool simple to operate, that efficient is high.
In order to achieve the above object, lathe bed one end of numerical control electrode chaser machining tool of the present utility model is equipped with main spindle box and chuck, and the planker of work supporting block and mounting cutter is housed on the bed ways, and improvements are that cutter is the chasing tool that is driven by unit head.In addition, the chasing tool case is directly installed on the middle carriage, and saddle and middle carriage pass through the screw mandrel transmission by the vertical and horizontal servomotor respectively, and servomotor is controlled by computer-controlled circuit.
When numerical control electrode chaser machining tool of the present utility model is worked, the electrode workpiece is by the main shaft driven rotary, chasing tool is driven by unit head and rotates, control system is according to software that sets in advance and the program of finishing, control drives the saddle of chasing tool case lengthwise movement and the middle carriage of transverse movement respectively, thereby comb mills out curved-line thread path and chamfering on workpiece, finishes the processing of electrode thread and surface quality automatically.Because chasing tool is a multiple cut, so cutter is not easy to wear, not only the machining accuracy of screw thread is guaranteed, and has improved work efficiency greatly.Adopt computer program control then both simplification operation and adjustment, help to improve machining accuracy and surface quality, make the frame for movement of lathe obtain simplifying again.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the chasing tool sizing mechanism of reinforcing structural representation among Fig. 1 embodiment.
Fig. 3 is the A-A of a work supporting block mechanism profile among Fig. 1 embodiment.
Numerical control electrode chaser machining tool among Fig. 1 is changed a social system with existing lathe.Lathe bed 10 1 ends are equipped with main spindle box 1 and air spider 2, and the planker of work supporting block 5 and mounting cutter is housed on the bed ways, and chasing tool case 9 is directly installed on the middle carriage 11, has saved upper slide rest.The chasing tool that unit head 7 drives in the chasing tool case 9.Saddle 12 and middle carriage 11 respectively by servomotor by vertical ball screw 4 and laterally ball screw 6 transmissions, servomotor is controlled by computer-controlled circuit, the setting of computer-controlled circuit parameter and showing is finished by control panel 8.Among Fig. 13 is electrode workpiece.
On middle carriage 12, be fixed with chasing tool sizing mechanism of reinforcing shown in Figure 2.This mechanism is mainly by radiai adjustment plate D-2, axial adjustment plate D-6, radially scale is near switch D-3, axially scale is formed near switch D-4.Radiai adjustment plate D-2 and the rectangular shape of axial adjustment plate D-6 all are shaped on regulating tank on the two right angle faces of radiai adjustment plate D-2.The one side of axial adjustment plate D-6 is fixed with axial scale near switch D-4 and travel switch D-5, the regulating tank of another side and radiai adjustment plate D-2 is connected, radially scale also is fixed near switch D-3 in the regulating tank of this face, and the regulating tank of another right angle face of radiai adjustment plate D-2 is connected by fixed connecting plate D-8 and middle carriage 11.Because the chasing tool sizing mechanism of reinforcing has been arranged, when therefore the numerical control electrode chaser machining tool of present embodiment is worked, at the good electrode workpiece 3 of clamping on request and after adjusting each parts, the quick length feed of chasing tool before this, when near workpiece end face, radially scale signals near switch D-3 and realizes coarse positioning, and by the vertical slow-motion of computer control chasing tool, when reaching Working position, axially scale signals near switch D-4 and realizes fine positioning, chasing tool begins horizontal slow-motion to cutting position simultaneously, and this moment, radially scale left workpiece near switch D-3.Then, the processing beginning, chasing tool is in length and breadth to penetration of a cutting tool.To be processed finishing, chasing tool under programme-control, automatically fast vertical and horizontal withdrawing, chamfering.In said process, travel switch D-5 plays the security insurance effect, can prevent to control chasing tool striking work when malfunctioning.
Work supporting block 5 concrete structures among Fig. 1 mainly are made up of positive and negative precision feeding screw mandrel 5-1, dial 5-2, roller 5-3, disappear crack nut 5-5, roller frame 5-6, pedestal 5-4 as shown in Figure 3.Be equipped with among the pedestal 5-4 of this mechanism can move horizontally about the two crack nut 5-5 that disappear, two disappear crack nut 5-5 respectively with forward and reverse screw-threaded engagement at positive and negative precision feeding screw mandrel 5-1 two ends, two disappear crack nut 5-5 top respectively with about two roller frame 5-6 be connected, two roller frame 5-6 go up each hinged roller 5-3.When rotating the positive and negative precision feeding screw mandrel 5-1 of this mechanism, two roller frame 5-6 move left and right about the crack nut 5-5 that disappears will drive, thereby can be through the electrode of the various different-diameters of roller 5-3 holding, make the numerical control electrode chaser machining tool of present embodiment have good adaptability, and guarantee desirable centering effect.
Obviously, the numerical control electrode chaser machining tool of this embodiment is changed a social system with traditional lathe, auxiliary facility is complete, adjustable link is reasonable, therefore have cost performance height, simple to operate, applied widely, the high outstanding advantage of machining accuracy, third world countries' welcome that will be subjected to domestic steel industry and lack of capital.
