Abstract
A spindle structure with double internally-sleeved pull rods comprises a spindle, wherein the spindle is arranged on a dynamic cutter head by bearings; a pull rod which is connected with a hydraulic cylinder is arranged at an inner hole of the spindle; and a cutter body is arranged at the end of the spindle. The pull rod comprises an external pull rod and an internal pull rod inside the external pull rod; the end of the external pull rod is fixedly connected with one end of an extension bar, and the other end of the extension bar is connected with the cutter body; the end of the internal pull rod is fixedly connected with a connector inside the cutter body; a reamer rod which is connected with a reamer is arranged at the central hole of the cutter body; and the reamer rod is connected with the internal pull rod. The spindle structure not only can be used for processing a valve seat ring but also can be used for processing a valve stem guide hole without replacing equipment, so that time and labor are saved, the working efficiency is improved, the production cost is reduced, and the valve seat ring and the valve stem guide hole have high coaxial precision.
Description
Technical field
The present invention relates to a kind of main axle structure, particularly a kind of interior cover dual-pulling rod type main axle structure is mainly used in valve retainer and guide hole that the processing engine cylinder covers.
Background technology
At present the main axle structure of the valve retainer that covers of processing engine cylinder comprises through bearing and is installed in the main shaft on the power-driven cutter head, and the place is provided with the pull bar that joins with hydraulic jack at the main shaft endoporus, and the termination of main shaft and pull bar is equipped with tool bodies.The rotation of main shaft can drive tool bodies and rotate, and the blade on the tool bodies can be processed valve retainer, and the action of feeding drives pull bar by oil cylinder and moves axially completion, and the blade that drives when pull bar moves axially in the tool bodies moves along slideway is oblique.The main axle structure function singleness of this structure can only be processed valve retainer, the guide hole that can't processing cylinder covers.The processing of guide hole also need utilize other special equipment to accomplish, wastes time and energy, and inefficiency, processing cost is high.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, can be respectively to valve retainer and guide hole process, time saving and energy saving, the interior cover dual-pulling rod type main axle structure of increasing work efficiency, cutting down finished cost, overcome the deficiency of prior art.
Cover dual-pulling rod type main axle structure in of the present invention; Comprise through bearing being installed in the main shaft on the power-driven cutter head, the place is provided with the pull bar that joins with hydraulic jack at the main shaft endoporus, and the termination of main shaft is equipped with tool bodies; Described pull bar comprises the draw-in bar that outside link is inboard with being positioned at outside link; The termination of outside link is fixedly connected with an end of extension bar, and the other end of extension bar and described tool bodies are joined, and the draw-in bar termination is fixedly connected with the interior connector of tool bodies; The tool bodies central hole is provided with the reamer bar that connects reamer, and reamer bar and draw-in bar join.
Between the cover dual-pulling rod type main axle structure in of the present invention, wherein said outside link and extension bar for being threaded; Be fixedly connected through connecting pin between described reamer bar and the draw-in bar; Described connector is threaded with draw-in bar.
Cover dual-pulling rod type main axle structure in of the present invention, because the duplex pull rod that matches with tool bodies and join with oil cylinder in the hydraulic control device is arranged in the main shaft inboard, during the processing valve retainer; Through interior lateral bracing strut reamer is retracted the tool bodies inboard, utilize the blade on the tool bodies to process valve retainer, reamer does not produce any influence to this; During the processing guide hole, draw-in bar is released reamer again, utilizes reamer to process guide hole; The centre need not more exchange device, and is time saving and energy saving, improved operating efficiency; Reduced processing cost, valve retainer is high with the coaxial precision of guide hole.
Description of drawings
Fig. 1 is the structural representation when reamer stretches out in the specific embodiment of the invention;
Fig. 2 is the structural representation when reamer is pulled in the specific embodiment of the invention.
The specific embodiment
Like Fig. 1, shown in 2: 5 is main shaft, and main shaft 5 is crossed three bearings 3 and is installed on the power-driven cutter head, and the axial limiting spare of bearing 3 comprises spacer 2 and nut 1, is processed with the distortion groove and the fastening bolt 18 that has been threaded on the nut 1.The axial limiting spare of bearing also comprises outer separator 4 and inner spacing collar 13.The endoporus of main shaft 5 is provided with outside link 14, is provided with draw-in bar 12 in the outside link 14.One end of the termination of outside link 14 and extension bar 6 joins through screw thread, and extension bar 6 matches with the endoporus of main shaft 5, can endwisely slip at the endoporus of main shaft 5.The termination of the termination of main shaft 5 and extension bar 6 is equipped with tool bodies, and tool bodies is that integral body is chosen parts.The inner connector of the termination of draw-in bar 12 and tool bodies 7 connects through screw thread.10 is reamer, and the termination of the reamer bar 17 that joins with reamer is fixedly connected and is positioned at the endoporus of connector 7 through connecting pin 16 and draw-in bar 12.
Since have in main shaft 5 inboards match with tool bodies and with the duplex pull rod that oil cylinder in the hydraulic control device joins, during the processing valve retainer, reamer is retracted the tool bodies inboard through draw-in bar 12; Utilize the blade 9 on the tool bodies to process valve retainer, reamer 10 does not produce any influence to this, during the processing guide hole; Draw-in bar 12 is released reamer 10 again, utilizes reamer 10 to process guide hole, and the centre need not more exchange device; Time saving and energy saving; Improved operating efficiency, reduced processing cost, valve retainer is high with the coaxial precision of guide hole.
