Embodiment Construction
[0035] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0036] see Figures 1 to 4 , which depicts the processing device and parts of the transmission sprocket on the escalator or moving walk of the present invention. It includes a machine tool workbench 1 of a machining center, and the machine tool workbench 1 is provided with a T-shaped slot 11 along its own length direction. A movable positioning structure 2 is arranged on both sides of the machine tool table 1 respectively, and the two positioning structures 2 are arranged along the same center line 100 . The machine tool table 1 is also provided with 6 contour pads 3 of the same shape, which are used to support the workpiece and ensure that the processing height of the workpiece on the machine tool table is the same. The six contour pads 3 are all boss structures, arranged in the T-shaped groove 11 according to left and right symmetry, and a...

The invention discloses a method and a device for processing a driving sprocket on an escalator or a moving sidewalk. According to the method, a twice clamping method is adopted, the front half part of a workpiece is processed during first clamping, meanwhile, left and right teeth of the workpiece are provided with grooves with working allowance, a positioning structure movably arranged on a lathe workbench is adhered and matched with the grooves so as to realize precise positioning; then the workpiece is lift up to rotate for 180 degrees along the center of an inner hole, the position of the groove of the left tooth is exchanged with that of the groove of the right tooth, and then the workpiece is put down along the positioning structure, so that precise positioning after 180-degree workpiece rotation is ensured by use of the positioning effect of the positioning structure; and finally, the rear half part of the workpiece is clamped and fixed at the lathe workbench and the positioning structure is moved away, so that processing of the other part of the workpiece is finished. The method can be used for realizing precise processing on large-specification driving sprockets by use of a small lathe, overcoming the defects in the prior and greatly saving the equipment cost.
Description
technical field [0001] The invention relates to a processing method and device for a transmission sprocket on an escalator or a moving walk. Background technique [0002] In the transmission system of escalators or moving walks, the transmission sprocket is a more important part. In addition to its own high precision requirements, it also has left and right parts symmetrical requirements. [0003] The common practice in the industry is to design a special fixture on the vertical machining center after turning, the left and right pieces are relatively superimposed, and the inner hole (bearing stopper) is used for positioning. After one clamping, the end mill is used to move the envelope Line to complete all the tooth groove processing and change the tool to complete the processing of all end faces. Practice has proved that this method is more reasonable and reliable. However, this method requires that the maximum diameter of the envelope of the transmission sprocket must be...
