Abstract
The utility model discloses a large optical machine tool grinding head which mainly solves the problem that the existing optical processing machine tool grinding head has the rotate speed alternating between slow and fast in work and is easy to damage. The machine tool grinding head is characterized in that the corresponding ends of a lower transmission shaft (2) and an upper transmission shaft (1) are connected with universal joints (3) respectively; the lower end of the universal joint (3) of the upper transmission shaft (1) is connected with an extension sleeve (4); the upper end of the universal joint (3) of the lower transmission shaft (2) is connected with an expansion link (5); and the extension sleeve (4) and the expansion link (5) are in up-down slip connection through an axial key. The large optical machine tool grinding head has the characteristics of stable rotate speed and long service life.
Description
Technical field:
The utility model relates to the used bistrique of optics manufacture field optical element surface correction burnishing machine, especially large-scale optics lathe bistrique.
Background technology:
At the optics manufacture field, the optics machining tool is a processing optical element visual plant.And bistrique is an optics machining tool important composition part.Bistrique is one and departs from rotary main shaft, and can adjust the equality working shaft of eccentric throw at any time, for main shaft revolution arranged, and itself is rotation also, like this optical element surface is revised polishing.At present, bistrique is at the revolution axle center part flexible axle to be housed, and drives eccentric shaft by servomotor by flexible axle and finishes the rotation grinding.And, when driving the eccentric shaft rotation, stress savings and release are arranged owing to flexible axle is an elastic shaft, thereby cause at bistrique work medium speed sometimes fast and sometimes slow, make processing optical element surface removal amount and surface roughness be difficult to control, and flexible axle is fragile, is unfavorable for applying.
The utility model content:
In order to solve existing optics machining tool the bistrique sometimes fast and sometimes slow and flimsy problem of rotating speed at work, the utility model provides a kind of large-scale optics lathe bistrique, and this large-scale optics lathe bistrique has the advantages that rotating speed is steady and service time is long.
The technical solution of the utility model is: this large-scale optics lathe bistrique comprises lower drive shaft and goes up power transmission shaft, be connected with universal joint respectively in lower drive shaft and last power transmission shaft corresponding end, the universal joint lower end of last power transmission shaft is connected with telescopic, the universal joint upper end of lower drive shaft is connected with expansion link, and telescopic slides up and down by axial bond with expansion link and is connected.
The utlity model has following beneficial effect: this large-scale optics lathe bistrique is because employing is connected with telescopic and expansion link structure by universal joint between lower drive shaft and last power transmission shaft, utilize the flexible of universal joint swing and telescopic and expansion link, realize that bistrique rotates and rotation around the center under the situation of different eccentric throws, realize the bistrique positive drive, thereby solve the sometimes fast and sometimes slow and flimsy problem of processing rotating speed that original elastic transmission brings, improved the optical element crudy, prolong bistrique service life, and simple in structure.This large-scale optics lathe bistrique has the advantages that rotating speed is steady and service time is long thus.
Description of drawings:
Fig. 1 is the utility model structural representation.
1-goes up power transmission shaft, 2-lower drive shaft, 3-universal joint, 4-telescopic, 5-expansion link among the figure.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
Shown in accompanying drawing, this large-scale optics lathe bistrique comprises lower drive shaft 2 and goes up power transmission shaft 1, be connected with universal joint 3 respectively in lower drive shaft 2 and last power transmission shaft 1 corresponding end, universal joint 3 lower ends of last power transmission shaft 1 are connected with telescopic 4, universal joint 3 upper ends of lower drive shaft 2 are connected with expansion link 5, and telescopic 4 and expansion link 5 slide up and down by axial bond and be connected.
Operation principle, this large-scale optics lathe bistrique is when work, last power transmission shaft 1 drives telescopic 4 by universal joint 3 and rotates, telescopic 4 drives expansion link 5 by axial bond and rotates, expansion link 5 drives lower drive shaft 2 by universal joint 3 and rotates, simultaneously by universal joint 3 swings, can be connected at axial stretching with being slidingly matched of expansion link 5 by telescopic 4, and then satisfy that bistrique rotates and rotation around the center under the situation of different eccentric throws, realize the bistrique positive drive, thereby solve the sometimes fast and sometimes slow and flimsy problem of processing rotating speed that original elastic transmission brings, improved the optical element crudy.
