Background technology
Can obtain low roughness value and high manufacturing accuracy by ultrasonic wave to metal surface processing, have that efficient is high, cost is low, free of contamination characteristics.Ultrasonic wave processing to the metal surface is finished by ultrasonic cutter, different ultrasonic cutters can be processed difform surface, ultrasonic cutter can be directly installed on the knife rest of corresponding lathe, or be installed on the supersonic machining apparatus, under the drive of supersonic machining apparatus, finish the ultrasonic wave processing to surface of workpiece.
In the existing document multiple ultrasonic metallic surface processing device is arranged, these application of installations are on the lathes such as engine lathe, numerically controlled lathe, milling machine, boring machine, grinding machine.Such as Chinese patent literature CN101502881 disclosed " ultrasonic metallic surface processing device for numerically controlled lathe ", CN101480733 disclosed " ultrasonic metallic surface processing device that is used for boring machine ", CN202079438U disclosed " ultrasonic metallic surface processing device that is used for grinding machine " and CN101851701A disclosed " ultrasonic metallic surface processing device that is used for milling machine or boring mill processing plane ".
But, said apparatus can only make ultrasonic cutter have a fixed position at lathe, can not automatically change the position of ultrasonic cutter, that is to say that a ultrasonic cutter only has a processing stations, can't in the workpiece clamped one time, finish two with the ultrasonic metal surface processing of upper surface.
Summary of the invention
The present invention is directed to the deficiency that existing ultrasonic metallic surface processing device exists, provide a kind of ultrasonic cutter that can make to have the multistation ultrasonic metallic surface processing device that a plurality of stations carry out ultrasonic metal surface processing.
Multistation ultrasonic metallic surface processing device of the present invention, by the following technical solutions:
This device comprises connecting plate, fixed disk and Connection Block; Fixed disk is connected on the connecting plate, and rotating shaft is installed in the fixed disk, and rotating shaft is connected with a rotating mechanism, and Connection Block is fixedly connected on the end that fixed disk is stretched out in rotating shaft, ultrasonic cutter travel mechanism is installed on the Connection Block and is used for the guide rail that ultrasonic cutter is installed.
Rotating mechanism comprises cavity, tooth bar, gear and rotating shaft position-limit mechanism, and cavity is arranged in the fixed disk, and tooth bar is installed in the cavity, and gear is installed in the rotating shaft, the rack and pinion engagement, and the rotating shaft position-limit mechanism is arranged on the fixed disk.The cavity of cavity as hydraulic cavities or cylinder can be used, move by in cavity, passing into hydraulic oil or Compressed Gas promotion tooth bar, the gear that is engaged with is rotated, and the gear driven rotating shaft is rotated, and the rotational angle by rotating shaft position-limit mechanism countershaft carries out spacing.
Described rotating shaft position-limit mechanism comprises Limit screw, nut and servomotor, and nut is installed in an end of cavity, Limit screw is connected on the nut, one end of screw rod stretches in the cavity, and the other end is connected with servomotor, and servomotor is installed on the guide rail that is fixed on the fixed disk.
Rotating mechanism also can adopt stepper motor, and rotating shaft one end directly is connected with stepper motor.
During use, whole device is fixedly connected on by connecting plate on the knife rest of lathe, and ultrasonic cutter is installed on the guide rail on the Connection Block and with travel mechanism and is connected.Ultrasonic cutter is mobile at guide rail under travel mechanism drives, and the contact surface of the work carries out leaving surface of the work after ultrasonic metal surface processing or the completion of processing.Rotating mechanism drives Connection Block by rotating shaft and rotates, and makes the ultrasonic cutter on the Connection Block transform to other position.
The present invention can realize that ultrasonic cutter changes station automatically, at needs ultrasonic metal surface is carried out on surface of workpiece and add man-hour, make ultrasonic cutter be in this surperficial Working position, other surface of workpiece is being added man-hour, make ultrasonic cutter turn to corresponding Working position, have simple in structure, good rigidly, easy to operate characteristics.

The specific embodiment
Such as Fig. 1, Fig. 2 and shown in Figure 3, ultrasonic metallic surface processing device of the present invention mainly comprises connecting plate 1, fixed disk 12 and Connection Block 5.Connecting plate 1 is used for whole device is fixedly connected on the knife rest of lathe.
Referring to Fig. 2, fixed disk 10 is connected on the connecting plate 1 and (is bolted or alternate manner), by bearing rotating shaft 4 is installed in the fixed disk 10, and gear 11 is installed in the rotating shaft 4.Rotating shaft 4 is multidiameter, and fixed disk 10 is all stretched out at two ends, and small end is locked by locking nut, on the large end Connection Block 5 is installed.Referring to Fig. 3, also be provided with cavity 12 in the fixed disk 10, tooth bar 9 in the form of piston is installed in the cavity 12, be provided with sealing ring between tooth bar 9 and the cavity 12.The cavity of cavity 12 as hydraulic cavities or cylinder can be used, fixed disk 10 is provided with hydraulic oil or inlet for pressurised gas and the outlet that is communicated with cavity 12.Hydraulic oil or Compressed Gas enter in the cavity 12, promote tooth bar 9 in cavity 12 interior movements.Gear 11 engagements (referring to Fig. 2) in tooth bar 9 and the rotating shaft 4.When tooth bar 9 moved, gear 11 rotated thereupon, and the rotating shaft 4 of gear 11 and the also simultaneously rotation of Connection Block 5 that connects with rotating shaft 4 are installed.
Connection Block 5 is U-shaped, and cylinder 6 and guide rail 7 are installed on the Connection Block 5.Ultrasonic cutter 2 is installed on the guide rail 7 and with the piston rod of cylinder 6 by slide block 8 and is connected, and ultrasonic cutter 2 can be mobile at guide rail 7 under the drive of cylinder 6.Cylinder 6 plays the effect of travel mechanism, also can use the replacements such as hydraulic cylinder, spiral travel mechanism, as long as it is mobile at guide rail 7 to drive ultrasonic cutter 2.On the ultrasonic cutter 2 with radiator fan 3.
For processing stations is limited, be provided with position-limit mechanism at fixed disk 10, this position-limit mechanism comprises Limit screw 13, nut 16 and servomotor 14, nut 16 is installed in an end of cavity 12, Limit screw 13 is threaded connection on nut 16, and an end of screw rod 13 stretches in the cavity 12, and the other end is connected with servomotor 14, servomotor 14 is installed on the guide rail 15 that is fixed on the fixed disk 10, can move along guide rail 15.Servomotor 14 drives screw rod 13 and rotates and move, realization limits the displacement of tooth bar 9 in cavity 12, thereby define the rotational angle of gear 11, rotating shaft 4 and Connection Block 5, finally determine to be installed in the processing stations of the ultrasonic cutter 2 on the Connection Block 5.The displacement that changes tooth bar 9 can make ultrasonic cutter 2 have a plurality of Working positions.
Also can drive rotating shaft 4 by stepper motor or other mechanism rotates.
