Abstract
The utility model discloses a horizontal boring lathe lengthening and boring device, and aims to overcome the defects that when two coaxial long-distant boring holes on the general horizontal boring machine are processed, twice alignments and twice clamping sizes are needed, and the precision error is great in the prior art; a supporting tailstock is arranged on one side of the tailstock of the general horizontal boring machine far away from a boring head box in the direction of a lathe bed; a Morse taper shank at one lengthening end of the boring bar is mounted in the Morse taper hole at the tail end of the boring bar on the boring head box; and the other end of the boring bar is supported on the supporting tailstock. The supporting tailstock for supporting the lengthening boring bar is increased on the rear side of the tailstock of the boring lathe; the lengthening boring bar is connected with the boring bar through a Morse taper; the lengthened boring bar is provided with two supporting points for supporting a tail rack and the tailstock, so that the rotation accuracy of the lengthening boring bar is ensured, the range of processing length can be enlarged, the disposable alignment and clamping process of the coaxial holes can be achieved, the processing size and accuracy error generated by the repeated hoisting and alignment can be reduced, the product quality is ensured, the processing efficiency is greatly improved, and the manufacturing cost is low.
Description
Technical field
The utility model belongs to the lathe class.
Background technology
The tyre crane that uses on the port and pier, gantry crane etc. all belong to main equipment, the counterweight of installing on the trolley frame of installing on the tyre crane, the gantry crane etc., and its appearance and size is also all very big.Process two holes of the coaxial and apart from each other of above-mentioned workpiece when needing boring, and scraping simultaneously is during perpendicular to the circumferential plane of nose end head, because existing common horizontal boring machine is subjected to the restriction of its processing length, two holes can not be carried out boring and scraping simultaneously, can only be earlier of needing the boring workpiece being placed on the workbench of boring machine centering fixes, boring is unloaded after finishing, again the workpiece other end is placed on the workbench, and be the fixing boring again of benchmark centering with the good hole of boring.
The mode of two holes of coaxial and apart from each other and periphery on the above-mentioned boring large-scale workpiece, owing to finish through twice centering, twice clamping and processing, all there are the error of size and precision aspect in two holes that process and circumferential plane, therefore can't guarantee the boring crudy.The crudy of workpiece does not guarantee, can have influence on the product quality of entire machine after the parts assembling after the processing, just can't guarantee the normal use of equipment yet, and also can shorten service life.
The utility model content
Technical problem to be solved in the utility model is, overcome the circumferential plane of the hole and the termination of scraping simultaneously of two coaxial apart from each others of prior art boring on common horizontal boring machine, add twice centering of needs in man-hour, twice clamping size and the big shortcoming of trueness error, a kind of lengthening borer of horizontal boring machine is provided.
In order to solve the problems referred to above that prior art exists, the utility model is to adopt following technical proposals to realize: leave boring head case one side at common horizontal boring machine tailstock, be provided with the support tailstock along the lathe bed direction, the Morse taper shank of lengthening boring bar one end is installed in the mohs tapered bore of the boring bar end on the boring head case, and its other end is supported on and supports on the tailstock.
The utility model also has following technical characterictic:
The installation of described support tailstock, be the boring machine tailstock from boring head case one side, be provided with base along the lathe bed direction, base is provided with many groups of not waiting from the tailstock distance fot screws that the support tailstock is used is installed;
The installation of described support tailstock, be the boring machine tailstock from boring head case one side, be provided with track along the lathe bed direction, support tailstock and install in orbit.
Advantage of the present utility model and good effect are, owing to increased the support tailstock that support lengthening boring bar is used in the back of common horizontal boring machine tailstock, the lengthening boring bar links together with the boring machine boring bar with the Mohs awl, make the boring machine boring bar obtain lengthening, boring bar behind the lengthening has tailstock and two strong points of tailstock, guaranteed the running accuracy of lengthening boring bar, the processing length scope of the common horizontal boring machine in lengthening back has also just obtained expansion, make for example tyre crane trolley frame, coaxial and the hole of apart from each other and the circumferential plane of termination on the large-scale workpieces such as door machine counterweight, can machine by a centering clamping, the repeatedly processing dimension and the trueness error of hoisting alignment generation have been reduced, guarantee product quality, improved working (machining) efficiency greatly; Simultaneously, strengthened the processing scope of application of common horizontal boring machine, reduced the vacancy rate of lathe, thereby reduced production cost.
Description of drawings
Fig. 1 is a mounting structure schematic diagram of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Among Fig. 1, common horizontal boring machine comprises lathe bed 1, and boring head case 2, workbench 4 and the boring machine tailstock 8 installed on the lathe bed 1 are equipped with boring bar 3 two ends of boring cutter 5, is installed in boring head case 2 respectively and is supported in the boring bar bearing 8.1 on the tailstock 8; Boring machine tailstock 8 from boring head case 2 one sides, be provided with base 9.1 along lathe bed 1 direction, erect on the base 9.1 the support tailstock 9 that supports lengthening boring bar 3.1 usefulness is installed, the Morse taper shank of lengthening boring bar 3.1 1 ends, be installed in boring bar 3 terminations, be positioned at the mohs tapered bore at nearly boring bar bearing 8.1 places, its other end is supported on and supports on the tailstock 9.
During work, to need on the workpiece 6 of boring band to need an end in boring hole 6.1 to be fixed on 4 of the workbench, the centre of workpiece 6 and have the other end that needs boring hole 6.1, supporting also with a two stands 7 respectively, centering is fixed, the boring bar 3 that boring cutter 5 is housed is connected and supports with lengthening boring bar 3.1 install, can carry out the circumferential plane of boring processing and scraping termination simultaneously two holes.
For the boring of remote coaxial aperture 6.1 on the large-scale workpiece 6 that adapts to different length, described base 9.1 is provided with to change and supports many groups fot screw that tailstock 9 is installed, and moves the position of supporting tailstock 9, just can adapt to the boring of multiple size type of workpiece 6.
The installation of described support tailstock 9 also can be along the direction of lathe bed 1 track to be installed on described base 9.1, supports tailstock 9 and installs in orbit, adjust apart from the time with convenient, quick.
