Description of the new type ... [Technical field to which the new type belongs] Mainly for the parallel biaxial sliding of the lathe dual-axis tailstock during drilling and tapping operations. Those who rise and fall. [Previous technology] Drilling and tapping are indispensable and important operations in the lathe operation, especially for drilling and tapping with different hole distances on the same axis, which can be completed at one time. Currently, parallel double taps are also used. The shaft type tailstock is used for operations. Earlier (as shown in Figure 1), as approved before this case, the application number 74209791 'is mainly used a double shaft type tailstock with a manual lever, and the shaft seat is laterally shifted left and right. The two axes can be used for continuous drilling and tapping of different apertures of the same work. After that, although the development of automatic hydraulic parallel biaxial tailstocks (see Figure 2) is faster and easier to operate However, when drilling and tapping, due to tailstock A, parallel double-drilling bushes 1 3 A and tapping bushes 1 4 A are used (5 A for drills and 16 A for tapping) With the automatic oil pressure to achieve left and right lateral displacement, so pay little attention to 'driller 1 5 A or tapper worker 6 a during automatic displacement, often hit the left and right tool holder 7A side , Causing inconvenience in operation and: interference, and even danger, unless, One seat is stretched to the end, so it adds a drill 1 5A, a tapper 6A and the work: travel, waste of man hours and manufacturing costs, especially the parallel two-axis tailstock ^ M260344 with the bottom The sliding seat 2 A is a horizontal type, and it takes up a lot of space when it is lifted on the entire set of lathes. Therefore, it is not economically and practical. Because the author of the dagger case is dedicated to the above-mentioned defects, Thinking, working hard, developing a more perfect "structure improvement of the lathe tailstock". [New content] Please refer to the third, fourth, and fifth drawings, which are exploded three-dimensional schematic diagrams, three-dimensional combined schematic diagrams, and sectional side-view schematic diagrams of the creation of this case. The creation of this case is a lathe tailstock 1, which mainly includes a vertical ) Type tapered shaft seat 10, the seat is provided with four shaft holes 101, 〇02, 工, 104, in which two shaft holes 丄 工, 〇〇2 are arranged in a hydraulic pressure Cylinder shaft 1 1, i 2 and pole sleeve workers, workers 2 workers, pole block workers 2, 122, and then a drilled shaft sleeve 1 3 is inserted in each of the middle two shaft holes 103 and 104. 1 、 tapping sleeve 1 4 and a drill 1 5 、 tapping device 丄 6, and then the hydraulic cylinder shaft 1 1 and 1 2 and drilling sleeve 1 1 3 A shaft block i 7, i 8, among which, the upright (vertical) type tapered shaft seat 1 〇 is used to embed one side tapered surface 1 0 5 into the inner tapered surface 20 of another L-shaped tapered surface slide 2 There are two hydraulic cylinder shafts 2 in the tapered slide seat 2 and a long slide 2 2 is supported. Finally, a bolt set 3 is used to lock the outside for fine-tuning left and right. The whole set of tailstocks 1 and L-shaped tapered slide seat 2 is in a state that can be raised and lowered, and A pc control box 5 is fitted on one side of the seat 1, and a hydraulic flow valve 5 1 and a drilling hole such as a limit switch 5 2 and a rear limit switch 5 3 are provided on the left and right sides of the upper end of the vehicle seat 10. A slide limit switch 5 4 is provided at the end of the sliding seat 2 in contact with the long slide M260344 plate 2 2, and a front limit switch 5 is set at the contact end of the slide 2 at the bottom 2 3 and the shaft seat 1 〇 '/ Bone seat 2 Bottom 2 3 Before the two sides, one tapping slow switch 5 6 and one post tapping limit switch 5 7 are set. In this way, they are the main components of this case. [Embodiment] When you want to operate the automatic operation of drilling first and then tapping, first turn on the power of the PC control box 5 and set various actions. At this time, the hydraulic cylinder shaft ii will touch the hydraulic flow valve 5 forward. 1. Make the drilling shaft sleeve i 3 drive the drill 丄 5 forward and perform the drilling action. When drilling to a predetermined depth, the drill 15 will return automatically because it hits the limit switch 5 2 before drilling. After returning, the limit switch 5 3 was encountered after drilling, and the spindle 6 resumed the rotation speed. At this time, the entire group of tailstock 1 will be separated from the bottom 2 3 of the tapered slide 2 at the same time. The slide plate 2 2 rises at a fixed distance on the inner cone surface 20 (as shown in the sixth figure) and touches the rear limit switch 5 4 of the tailstock. At this time, the hydraulic cylinder shaft 丄 2 'will advance the tapping shaft The sleeve 1 4 drives the tapping device i 6 forward. At this time, the rotation speed of the main shaft 6 will slow down synchronously. 'When the current tapping device 丄 6 approaches the work quickly, it will touch the tapping slow switch 56' to make the main shaft 6 run synchronously. When the tapping reaches the pre-depth, because the pre-tapping limit is encountered _5 5, the spindle 6 is synchronously reversed, and the tapping device 16 is automatically returned, and the post-tapping limit switch is 5 7 Canton restores the original rotation speed by itself, and the whole group of tails drops with Duck 22, so that the hole and the tapping are completed. _: Automatic M260344 The emphasis of the creation of this case is the vertical (vertical) drilling of the tailstock 1. The tapping double shaft sleeves 13 and 14 drive the drill 1 and 5. The tapping device 16 lifts up and down at a certain distance on the tapered slide 2 so as to achieve one automatic operation of drilling and tapping. Such an upright structure The design is because the drill 15 and tap 16 are up and down during automatic displacement, so they will never hit the left and right tool post 7 sides, so as to improve the safety and convenience of operation, and less The space for lathe work is more economical and practical.

The second diagram is the general schematic diagram of the automatic hydraulic parallel biaxial tailstock lathe. This is a three-dimensional combination diagram created in this case.
