Abstract
The present utility model discloses a center rest precision detection system which comprises a first guide sleeve, a second guide sleeve and a concentric indicator. The first guide sleeve and the second guide sleeve comprise axially through inner bores, and the inner bore diameter of the first guide sleeve is smaller than that of the second guide sleeve. The inner bore diameter of the first guide sleeve is the same as the diameter of an installing rod of the concentric indicator. The installing rod of the concentric indicator is penetrated into the inner bore of the first guide sleeve to be movably connected with the first guide sleeve. A gauge head of the concentric indicator is leaned against the inner bore wall of the second guide sleeve. The second guide sleeve is fixed on the center rest. By adopting the system, the center rest precision can be rapidly detected, the precision can be controlled within 0.01mm, and the system is suitable for lathe center rests of various models.
Description
Technical field
The utility model relates to the lathe field, particularly relates to the lathe centre frame accuracy detection system of various models.
Background technology
The installation of numerically controlled lathe centre frame, existing technology are to install cubing additional in two top centres, are the precision that benchmark removes inspection center's frame with the cubing.Because the size of centre frame differs, cause its cubing of centre frame of different model can not be general, and the quantity of different lathe model demand centre frames differs, so the cubing demand be varied, has improved processing cost.And, detect with two top methods, because the stressed meeting of tailstock brings certain influence to the centre frame accuracy detection, and the precision of centre frame directly influences the processing work precision.Think the accuracy that improves accuracy detection and the cost of control cubing, need the new detection system of exploitation.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes prior art, and the system of a kind of accurate, low-cost inspection center frame precision can be provided.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of centre frame accuracy detection system is provided, comprises: first guide pin bushing, second guide pin bushing and indicator with one heart.First guide pin bushing and second guide pin bushing comprise the endoporus that connects vertically, and the first guide pin bushing internal orifice dimension is less than the second guide pin bushing internal orifice dimension.The first guide pin bushing internal orifice dimension is identical with the mounting rod diameter of concentric indicator.The indicator mounting rod penetrates the first guide pin bushing endoporus with one heart, flexibly connects with first guide pin bushing.The indicator gauge outfit leans against on the second guide pin bushing inner hole wall with one heart.Second guide pin bushing is fixedly mounted on the centre frame.
Preferably, the first guide pin bushing internal orifice dimension is 10mm, and the second guide pin bushing internal orifice dimension is 35mm.
Preferably, first guide pin bushing and second guide pin bushing include side opening perpendicular to axial direction.
The utility model centre frame accuracy detection system can fast detecting centre frame precision, and precision can be controlled in the 0.01mm, and is applicable to the lathe centre frame of various models.
Description of drawings
Fig. 1 is the side view of Φ 32 guide pin bushings of the utility model centre frame accuracy detection system;
Fig. 2 is the upward view of Φ 32 guide pin bushings of the utility model centre frame accuracy detection system;
Fig. 3 is the utility model centre frame accuracy detection system schematic.
The mark of each parts is following in the accompanying drawing: 1, claw, 2, jackscrew, 3, Φ 10 guide pin bushings, 4, indicator with one heart, 5, the centre frame claw, 6, Φ 32 guide pin bushings.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1, the utility model provides a kind of centre frame accuracy detection system, comprises two guide pin bushing: Φ, 10 guide pin bushings 3 and Φ 32 guide pin bushings 6, and indicator with one heart.
The diameter of bore of Φ 10 guide pin bushings 3 is 10mm.
See also Fig. 2 and Fig. 3, the outside diameter of Φ 32 guide pin bushings 6 is 40mm, diameter of bore 32mm; Its accuracy requirement is higher; Cylindrical and endoporus right alignment and cylindricity accuracy requirement are in 0.01mm, and the low precision of surveying with concentric indicator like this is little, and the center of tool bore is also found easily.
On the hole wall of Φ 10 guide pin bushings 3 and Φ 32 guide pin bushings 6, edge two axial vertical directions of guide pin bushing therewith has side opening, supplies the jackscrew 2 of lathe to insert, and guide pin bushing is fixedly secured in the detection position.
Claw 1 with lathe clamps Φ 10 guide pin bushings 2 with jackscrew 2, and the installation shaft of indicator 4 is inserted the endoporus of Φ 10 guide pin bushings 3 with one heart, clamps Φ 32 guide pin bushings 6 with lathe centre frame claw 5 and jackscrew, and the gauge outfit of indicator 4 is beaten on Φ 32 guide pin bushings 6 inner hole walls with one heart.
Detection mode sees also Fig. 1.By the above structure mounting center frame accuracy detection system.Rotate concentric indicator 4 main shafts,, check in vertical direction indicator 4 table rotation value with one heart then earlier through concentric indicator 4 centering Φ 32 guide pin bushing 6 centers in the horizontal.With one heart the gauge outfit of indicator 4 under move to when lasting, if indicator 4 is shown pointers and is rotated counterclockwise with one heart, show that then the centre frame center is too high, height difference is concentric indicator 4 indicator differences.After detecting this difference, adjust the centre frame height, remove same height, the position that can debug centre frame through grinding center frame adjusting pad.
The utility model can be more accurate the height of measuring centre frame, faster than tradition inspection rod speed, precision is higher, and is easy to operate, and is applicable to the centre frame of various models.
The above is merely the embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model instructions and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
