Description
Technical field
The utility model relates to a kind of metal working machine tool, especially the lathe of processing metal revolving body.
Background technology
With digital camera, digital gamma camera is in the numerous digital products and precision instrumentation of representative, a lot of high-precision metal cutting parts is arranged, particularly small eccentric shaft; Because the little precision height of part is bigger with the machine tool manufacture difficulty; Mainly be: 1, the part eccentric direction is uncontrollable; 2, part clamps difficulty; Because the clamping position of part is short, main shaft is in level makes the center of gravity of part drop on beyond the clamping area, must hold comparatively difficulty to part during clamping; 3, the feeding of cutter can't accurately be controlled, and machining accuracy is low.
The utility model content
Technical problem to be solved in the utility model is the deficiency that overcomes the above-mentioned background technology, and a kind of improvement of eccentric lathe is provided, and this lathe should be able to be processed small eccentric shaft effectively, has the advantages that parts fixation is reliable, machining accuracy is high; And production efficiency height, operation facility.
The technical solution adopted in the utility model is: the eccentric machine of special-purpose vehicle, comprise main shaft and at least one knife rest that eccentric clamping is housed, and main shaft and knife rest are driven by driving-chain by power set respectively; It is characterized in that described main shaft is arranged vertically, described eccentric clamping is installed in the top of main shaft; Described knife rest is positioned on the track of vertical setting, and the feed campaign of knife rest is realized by the driving of power set by lever and cam mechanism.
Described lever and cam mechanism comprises the cam that driven by power set and by this cam-actuated lever; Lever is hinged on the column, and the right-hand member of lever is subjected to the roof pressure of cam, and the left end of lever then promotes described knife rest and slides along the track realization feed campaign.
Described knife rest also is subjected to the application of force of a returning spring, so that it possesses the potential energy that up slides.
Described track is a mutual chimeric dovetail groove between knife rest and the carriage saddle.
Described power set are motors.
Operation principle of the present utility model is: motor makes the eccentric clamping on main shaft top drive the part to be processed one superhigh speed rotation of clamping by the driving-belt drive shaft; The motor-driven cam rotates simultaneously, and cam promotes lever swing again, and the other end of lever makes its (overcoming the pressure of returning spring) move downward along track with regard to the roof pressure knife rest, and the lathe tool on the knife rest has just been realized machining to processing parts; After cutting was finished, cam disappeared by the roof pressure power of lever to knife rest, and knife rest is promptly driven by returning spring institute applied pressure and gets back to original position.
The beneficial effects of the utility model are: 1, main shaft changes into and being arranged vertically, as long as part is placed on the locating surface of eccentric clamping, need not during clamping part is held during work, brings very big facility to clamping parts; 2, install the self-acting feed system that controls with cam additional, can control the starting and ending position of feed more accurately, more accurately control the feeding uniformity of cutter, guarantee machining accuracy; And be provided with rough turn, two control of finish turning cam, can further improve machining accuracy; 3, adopted eccentric clamping and knife rest, not only can guarantee the processing request of part, and the cost of equipment also has been able to further reduction as standard component; 4, productivity ratio height; Operating personnel only need clamping part to be processed and take off finished product, and all the other processing feeds all can be carried out automatically; So the production efficiency height is particularly suitable for part processing in batches.

The specific embodiment
As shown in the figure, the eccentric machine of special-purpose vehicle, eccentric clamping 7 is equipped with on the top of the main shaft 6 of this machine, and vertical, rotatablely is positioned on the carriage 5 (passing through bearing); Power set (motor 16) rotate by driving-chain (belt 20) drive shaft.This machine is provided with at least one knife rest 9 again, and this knife rest is positioned on the track of vertical setting; Among the figure as can be known: carriage saddle 8 is fixed on the column 4, and described track is a mutual chimeric dovetail groove between knife rest and the carriage saddle.Described knife rest is a standard component, and directly outsourcing obtains.
Described lever and cam mechanism comprises the cam 1 that driven by power set and by this cam-actuated lever 13; Among the figure, the top of column is by the jointed shaft 11 articulated levers 13 on the back-up block 12, and alignment pin 15 roof pressures of lever right-hand member are on the circumferential working face of cam; The screw roof pressure that the lever left end is fixed is on knife rest 9 top adjustment screw 10.Like this, after power set (motor 18) rotated by reductor 17 and driving-belt driving cam, the swing of activation lever again promoted knife rest and carries out the feed campaign along carriage saddle 8 toward lower slider.Because the feed velocity of the circumferential working face shape decision knife rest of cam, so need be according to the material of processing parts, different requirements such as machining accuracy roughness, the design and the lifting curve of machining cam are with the machining accuracy of the eccentric element of guaranteeing the requirement of various unlike material different technologies.
Among Fig. 4 as can be known: pull bar 26 is connected on the lever after upwards passing through from the hole of knife rest, wear a spring 25 on the pull bar again, the bottom of spring is by the pull bar holding, the upper end of spring just applies knife rest and upwards pressure, knife rest 9 is possessed up slide to be back to the potential energy of original position, also make the fixing screw of lever left end all the time roof pressure on the adjustment screw 10 on knife rest 9 tops.
Described eccentric clamping 7 is standard components, and directly outsourcing obtains.Be provided with eccentric positioning structure in this eccentric clamping, the eccentric direction of eccentric clamping can be adjusted correctly in advance; During parts fixation,, convenient laborsaving again as long as clamping part behind the locating hole 7-1 at part insertion eccentric clamping center.
Further, the symmetry direction of the utility model around eccentric clamping arranged two knife rests, with two cam control feeds, carries out rough turn and finish turning simultaneously respectively; Not only make rough turn, finish turning in a circulation, finish, and rough turn cutter 22 is 180 degree symmetric arrangement with shaving tool 23, rough turn, finish turning can be cancelled out each other to the influence that promotes on one side to part at cutting force radially, the possibility of the cutter relieving when having reduced thin and long units turning, crudy is also further promoted.
Also have among the figure: the regulating handle 27 of control knife rest move left and right.
