Abstract
The utility model discloses a loom cam opening separating device which composes of a cam shaft installed inside the case, a separating shaft and a handle installed outside the case and fixed with the separating shaft, which is characterized in that an eccentric shaft in installed on the part of the separating shaft inside the case and a swing arm is installed on the eccentric shaft. The advantages of the present utility model are: (1) Transmission is stable and accurate, labor saving, and reliable. (2) During normal operation, the device can accurately sticks to corresponding matched cam plates together with the two bearing rotors on the swing arm without any collision and vibration. (3) The handle is easy and convenient to operate with high transmission efficiency, and is convenient for installation and maintenance.
Description
One, technical field
The utility model relates to a kind of loom cam shedding motion, particularly a kind of loom cam opening separator.
Two, background technology
Cam opening device is one of moving component main in the loom, and wherein cam swing arm is again one of critical piece in the cam opening device.In when design, to the requirement of cam opening device or swing arm be: when preventing to have a power failure, surface of second order occurs inhomogeneous; When changing kind and changing beam warp, all heald frames can remain on the same horizontal line on the loom, the installation of being convenient to heald and combining folder; Shedding cam is separated and the energy balance with swing arm, be convenient to change cam bit, thereby reach the kind of changing fabric.Above-mentioned requirements generally is achieved by separating mechanism, and existing separating mechanism has multiple, have nothing in common with each other, as:
Chinese patent ZL03222045.6 discloses a kind of " cam swing arm separating mechanism ", this cam swing arm separating mechanism mainly by a linking arm that links to each other with swing arm, the eccentric cam that is set in the seat chamber that is positioned at the linking arm other end realizes that swing arm separates.But this mechanism driving torsion is bigger, serious wear, and processing, installation are easy to generate error, are easy to generate collision, vibration and operating noise between the moving component.Particularly, this mechanism does not have auto-lock function, and eccentric cam can rotate arbitrarily, and then the displacement accuracy of uncontrollable swing arm.
Chinese patent ZL03259675.8 discloses a kind of " putting cam opening device on the water jet looms active type ", and the link assembly that cam swing arm separating mechanism is wherein mainly formed by crank, connecting rod realizes that swing arm separates.But there is same problem in this mechanism, and complex structure, and glade plane space is arranged, and is easy to generate contact-impact and vibration, thereby increases wearing and tearing and noise.Simultaneously, this mechanism equally can not self-locking.
Three, summary of the invention
1, goal of the invention: the purpose of this utility model be provide at the deficiencies in the prior art a kind of simple in structure, vibration is little, noise is low, in light weight, separate reliable loom cam opening separator.
2, technical scheme: loom cam opening separator described in the utility model, comprise the camshaft, the declutch shaft that are installed in the casing, and be positioned at casing outer with the fixing handle of declutch shaft, it is characterized in that being positioned at casing on declutch shaft one section is provided with eccentric shaft, and swing arm is installed on this eccentric shaft.
In order to guarantee machining accuracy, improve the reliability of motion, be respectively equipped with in the both sides of described eccentric shaft and the fixing support of casing, declutch shaft is installed on this support.Simultaneously, camshaft can be installed in described support.
For swing arm is remained on the same straight line, on the bottom surface of casing, be provided with a positive stop lug boss when separating.
In order to guarantee declutch shaft, on handle set, be provided with and screw thread pin-and-hole that casing is fixing in work or stable during released state.
Operation principle of the present utility model is: drive the rotation of declutch shaft by the rotation of handle, the rotation of declutch shaft drives the rotation of the eccentric shaft on it, the rotation of the rotating band movable pendulum arm of eccentric shaft, when the distance of shaft centers of the axle center of eccentric shaft and camshaft from hour being duty, at this moment, the corresponding applying of two rotors in the swing arm with conjugate cam.The distance of shaft centers that makes the axle center of eccentric shaft and camshaft when turning handle again is a released state during from maximum, and at this moment, two rotors in the swing arm separate fully with conjugate cam.Simultaneously, owing to be provided with positive stop lug boss in the bottom surface of casing, the following back side of swing arm contacts fully with boss, is the flat state of combining this moment.
3, beneficial effect: the utility model is compared with existing, and its remarkable advantage is: (1) stable drive is accurate, laborsaving, and stable drive is reliable.(2) during operate as normal, can be exactly with swing arm on two bearings rotor corresponding applying conjugate cam sheet and do not produce collision and vibration.(3) lever operated laborsaving, convenient, the transmission efficiency height is safeguarded easy for installation.

Fig. 3 is the structural representation of declutch shaft.
Fig. 4 is the structural representation of support.
Fig. 5 is the structural representation of handle set.
Five, the specific embodiment
As shown in the figure, separating mechanism comprises handle 4 and the handle set 5 that places outside the casing 3.Handle set 5 is fixed with an end that passes the declutch shaft 2 of casing 3.The mid portion of declutch shaft 2 is an eccentric shaft 6, and for the ease of processing, the path of this eccentric shaft 6 is identical with the radius of declutch shaft.Declutch shaft 2 is installed on two supports 8, and these two supports 8 lay respectively at the both sides of eccentric shaft 6, and fixing with casing 3.Simultaneously, in order to improve stability, camshaft 1 also is installed on these two supports 8.Eccentric shaft 6 and declutch shaft 2 are as same axis at this moment, and its interlude is an eccentric segment, the axis parallel offset of the axis of eccentric shaft and declutch shaft 2, and several swing arms 7 are placed on the eccentric shaft 6.Be provided with the boss 9 at 7 times back sides of restriction swing arm in the bottom surface of casing 3.A pair of screwed hole is set on handle set 5, on casing 3, is provided with a corresponding pin-and-hole.Pull handle by counterclockwise direction, then the two bearings rotor is thrown off gradually with corresponding cam bit in the swing arm, separates.Swing arm this moment displacement backward, the swing arm downside back side contacts with the projection that tank floor is set, and makes all swing arms on a plane, is the flat position of combining this moment.
