具体实施方式detailed description
下面结合附图和实施例对本发明进一步说明。The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
如图1-图2所示，可调锯解轨迹式金刚石框架锯，包括飞轮1、曲柄连杆2、平动架3、凸轮4、凸轮连杆5、锯框6、锯框摆杆7、轴承座8、传动轴9、齿条10、齿轮11。平动架3仅有水平方向移动自由度，具体的实现方式有很多，可以通过滚轮导轨也可以通过静压导轨来实现，锯框摆杆7与锯框6、平动架3分别铰接，锯框摆杆7共有四组，轴承座8固定于平动架3上，凸轮4通过凸轮连杆5与锯框6铰接，凸轮连杆5共有两组。平动架3下方有提升工作台13，专门放石材荒料，提升工作台13上下往复运动。As shown in Figure 1-Figure 2, the adjustable sawing trajectory diamond frame saw includes flywheel 1, crank connecting rod 2, translation frame 3, cam 4, cam connecting rod 5, saw frame 6, saw frame swing rod 7 , Bearing seat 8, drive shaft 9, rack 10, gear 11. The translation frame 3 only has the degree of freedom to move in the horizontal direction. There are many specific implementation methods, which can be realized by roller guide rails or static pressure guide rails. The saw frame swing bar 7 is hinged with the saw frame 6 and the translation frame 3 respectively. There are four groups of frame pendulum bars 7, the bearing block 8 is fixed on the translation frame 3, the cam 4 is hinged with the saw frame 6 through the cam connecting rod 5, and the cam connecting rod 5 has two groups. Lifting workbench 13 is arranged below translation frame 3, and stone material blocks are specially put, and lifting workbench 13 reciprocates up and down.
传动轴9上装有凸轮4、齿轮11，传动轴9由轴承座8支撑。齿轮12与固定在机架上的齿条11啮合，凸轮4、齿轮11分别有两副，对称布置于传动轴两侧，凸轮4、齿轮11与传动轴9通过键连接，凸轮4与凸轮连杆5上凸轮滚子线接触。Cam 4, gear 11 are housed on the transmission shaft 9, and transmission shaft 9 is supported by bearing block 8. The gear 12 meshes with the rack 11 fixed on the frame. The cam 4 and the gear 11 have two pairs respectively, which are symmetrically arranged on both sides of the transmission shaft. The cam 4, the gear 11 and the transmission shaft 9 are connected by keys, and the cam 4 and the cam Cam roller line contact on rod 5.
如图3所示，是本发明理论锯解轨迹示意图，平动架3为水平往复运动，锯框6作水平方向往复运动与竖直方向往复运动的复合运动，由于上述的复合运动，锯条刀齿切割石材荒料形成的切缝底面为近似圆弧面，即刀具轨迹12，此时刀齿可以实现单向切削。As shown in Figure 3, it is a schematic diagram of the theoretical sawing trajectory of the present invention. The translation frame 3 is a horizontal reciprocating motion, and the saw frame 6 is a compound motion of horizontal reciprocating motion and vertical reciprocating motion. Due to the above-mentioned compound motion, the saw blade The bottom surface of the slit formed by the tooth cutting the stone block is an approximate circular arc surface, that is, the tool track 12, and the knife tooth can realize unidirectional cutting at this time.
图4是传统框架式锯机切割轨迹图，图中刀齿切割石材荒料形成的切缝底面为一条直线，即图中刀具轨迹12，此时刀齿为双向切削，很容易导致刀齿脱落，影响刀齿使用寿命。Figure 4 is a cutting trajectory diagram of a traditional frame saw machine. In the figure, the bottom surface of the slit formed by cutting stone blocks with the knife teeth is a straight line, that is, the tool track 12 in the figure. At this time, the knife teeth are bidirectional cutting, which can easily cause the knife teeth to fall off , affecting the service life of the cutter teeth.
本发明的工作原理：金刚石框架锯基础上增加平动架3、凸轮4、凸轮连杆5、锯框摆杆6、齿轮11、齿条10等机构。平动架3在飞轮1的作用下做往复直线运动，由于固定在机架上的齿条10与固定传动轴上的齿轮11啮合，在平动架3做往复直线运动的同时，使得齿轮11相对于固定在机架上的齿条10做旋转运动，又由于齿轮11是固定在传动轴9上的，从而使传动轴9做相应的旋转转动，从而使固定在传动轴9上的凸轮4往复转动；又由于凸轮连杆5上的滚子与凸轮4的轮廓线线接触，在凸轮4的作用下，锯框6相对于平动架3做竖直方向与水平方向的复合运动。根据实际生产要求，更换凸轮4即改变凸轮的轮廓线，就可调整锯框相应的锯解运动轨迹。在对石材荒料进行切割时，由于锯框上述的复合运动，可以使锯条实现去切割空回程这种单向切割方式。Working principle of the present invention: on the basis of the diamond frame saw, mechanisms such as a translation frame 3, a cam 4, a cam connecting rod 5, a saw frame pendulum 6, a gear 11, and a rack 10 are added. The translation frame 3 makes a reciprocating linear motion under the action of the flywheel 1. Since the rack 10 fixed on the frame meshes with the gear 11 on the fixed transmission shaft, the translation frame 3 makes a reciprocating linear motion while the gear 11 Rotate relative to the rack 10 fixed on the frame, and because the gear 11 is fixed on the transmission shaft 9, the transmission shaft 9 is rotated accordingly, so that the cam 4 fixed on the transmission shaft 9 reciprocating rotation; and because the roller on the cam link 5 is in contact with the contour line of the cam 4, under the action of the cam 4, the saw frame 6 performs a compound motion in the vertical direction and the horizontal direction relative to the translation frame 3. According to actual production requirements, replacing the cam 4 means changing the contour line of the cam, so that the corresponding sawing movement track of the saw frame can be adjusted. When cutting stone blocks, due to the above-mentioned compound movement of the saw frame, the saw blade can realize the one-way cutting method of cutting empty return.
