Abstract

The utility model relates to the machining field of a surveying and mapping instrument, in particular to a main tube boring tooling which comprises a hand wheel, lead screw frames, a lead screw, sliding block seats, a left sliding block, a right sliding block, a base plate, a locating shaft, a pressing plate, an ejection rod, and a spring, wherein two lead screw frames are internally provided with bearings and are fixed at two sides of the base plate, the lead screw penetrates through the two lead screw frames, the left sliding block and the right sliding block are respectively arranged on the two sliding block seats and are sheathed at two ends of the lead screw by the threaded fit, the hand wheel is tightly fastened with the lead screw together, and the locating shaft is tightly fixed with the base plate together. In the main tube boring tooling, the difficult problem that one-side location is unreliable when the overall dimension of a processed workpiece is changed. Compared with the existing lathing hole, the symmetry degree of a processing hole relative to the appearance of the hole is ensured and the working efficiency is improved by about three times.

Description

The body tube boring technological equipment
Technical field
The utility model relates to the machined field of instrument of surveying and mapping, is exactly the manufacture field of spirit level body tube specifically.
Background technology
Body tube is a strength member on the spirit level, and its function is that all parts in the spirit level are assembled together with it, thereby forms a complete product.The processing of the most important position of spirit level body tube endoporus in the past all is usually on lathe, and body tube is fixed on the bent plate frock, and the location of its circumferencial direction generally all is to finish by a dog screw of side.Jia Gong weak point one is that working (machining) efficiency is low like this; The 2nd, when processed die casting profile changed, the circumferencial direction location was unreliable, occurs the hole and the profile asymmetry that process easily.
The utility model content
The purpose of this utility model is to overcome original technical deficiency, and a kind of body tube boring technological equipment is provided, and improves working (machining) efficiency and positioning accuracy.
For realizing above purpose, the technical solution adopted in the utility model is: the body tube boring technological equipment, it is characterized in that, and comprise handwheel; The leading screw frame; Leading screw; Take-up housing; Left slider; Right slide block; Substrate; Locating shaft; Described leading screw frame has two, and bearing is housed in it, is fixed on the both sides of substrate; Leading screw passes two leading screw framves; Left and right slide block seat respectively is enclosed within the leading screw two ends on two take-up housings and by threaded engagement, handwheel and leading screw tighten together, and locating shaft and substrate are fixed together.
The utility model has the advantages that: revolve screw about the circumferential registration of work piece adopts and drive two slide block self-centerings respectively and clamp work piece.Solved the insecure difficult problem in one-sided location when changing because of work piece appearance and size.When the processing work piece, by the big palette handwheel big palette is moved to tool orientation, finish the bore hole operation.Not only guaranteed compared with in the past car hole that machining hole was with respect to the symmetry of profile but also improve about 3 times of work efficiency.
Description of drawings
Fig. 1 is the utility model structural representation front view, wherein: 1 handwheel; 2 leading screw framves; 3 leading screws; 4 take-up housings; 5 left sliders; 6 work pieces; 7 right slide blocks; 8 spring bases; 9 substrates.
Fig. 2 is the utility model structural representation left view, wherein: 1 handwheel; 2 leading screw framves; 6 work pieces; 9 substrates; Locating shaft 10.
Fig. 3 is the utility model structural representation vertical view, wherein: 1 handwheel; 2 leading screw framves; 3 leading screws; 4 take-up housings; 5 left sliders; 6 work pieces; 7 right slide blocks; 8 spring bases; 9 substrates; Bearing 11; Pressing plate 12; Push rod 13; Spring 14.
The specific embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, the body tube boring technological equipment comprises handwheel 1; Leading screw frame 2; Leading screw 3; Take-up housing 4; Left slider 5; Work piece 6; Right slide block 7; Spring base 8; Substrate 9; Locating shaft 10; Bearing 11; Pressing plate 12; Push rod 13; Spring 14; Described leading screw frame 2 has two, and bearing 11 is housed in it, is fixed on the both sides of substrate 9; Leading screw 3 pass two leading screw framves 2 just can only the original place rotation and can not having moved axially; Left slider 5, right slide block 7 seat respectively are enclosed within the leading screw two ends on two take-up housings 4 and by threaded engagement, so can only moving axially along leading screw; Like this when rotating threaded shaft, left and right sides slide block will be simultaneously moves or side shifting outside two simultaneously to the centre.Handwheel 1 tightens together with leading screw 2, is used for clamping the operation of work piece; Locating shaft 10 is fixed together with substrate 9, plays the effect into work piece 6 centering.
Described leading screw frame one side is fixed with spring base 8, and push rod 13 and spring 14 are equipped with in the spring base the inside, and push rod withstands leading screw 3 ends by spring, has influence on positioning accuracy to prevent leading screw because of axial float.
Also be provided with pressing plate 12 on the described substrate, be used to compress work piece, and it is fastened on the substrate.
The screw thread at described leading screw two ends is respectively that left hand thread and right-handed thread are so that cooperate with left slider 5 and right slide block 7.
Frock of the present utility model is fixed on the lathe big palette, moulding cutter clamping in the machine tool chief axis hole, is just utilized the used car bed as boring machine.By locating shaft 10 centering, seat turns clockwise leading screw 3 by rotation hand wheel 1 on substrate 9 with work piece 6, moves from two side direction centers respectively thereby drive left and right sides slide block, clamps the head of work piece.So just finished the circumferencial direction location of work piece with respect to the locating shaft center.No matter work piece appearance and size is either large or small, all can be clamped in the centre position automatically, and can not be produced deflection with respect to the locating shaft center.Use pressing plate 12 that work piece is fastening then.Work piece is just located fully and has been fastened on the substrate like this.
After work piece fixed, it was close towards the moulding cutter that is rotating to make big palette drive illustrated parts by lathe big palette handwheel, and the moulding cutter enters the work piece endoporus, divided thick right boring boring to survive the interior shoulder hole of work piece shown in Figure 2.After finishing this preface processing, with handwheel 1 rotation counterclockwise, leading screw will drive left and right sides slide block and withdraw from from clamped position respectively, and the location of unclamping work piece clamps.Unclamp pressing plate and take out work piece, this preface has just been finished.
