Abstract
The utility model discloses a correcting device for the propping and tightening force of a tailstock of a horizontal machine tool. At present, in the machine tool manufacturing industry, the problem about the axial propping and tightening force of the tailstock of the horizontal machine tool is not widely paid attention to, but the technical indicator of the propping and tightening force plays an important role in the evaluation of the processing precision and performance of the machine tool, and directly has an influence on the precision and quality of processed components. According to the correcting device, a main shaft detection rod, a dynamometer and a tailstock detection rod are arranged between a headstock and the tailstock during the force measurement, and the correcting device can be used for detecting whether the propping and tightening force of the tailstock is consistent with the number value of the pressure gauge on the tailstock or not, so as to detect and correct the propping and tightening force of the tailstock of the horizontal machine tool.
Description
Technical field
The utility model relates to a kind of horizontal machine tool tailstock pressure means for correcting, belongs to horizontal machine tool precision techniques field.
Background technology
Horizontal machine tool is mainly by lathe bed, headstock, form with parts such as manometric tailstock and electrical equipment.In lathe manufacturing, the axial pressure problem of horizontal machine tool tailstock is not paid attention to widely at present, and that this technical indicator plays a part in the machining accuracy performance evaluation of lathe is crucial, and it directly affects the precision quality of processing parts.Because tailstock tool pressure numerical value is uncertain, make part's machining errors bigger than normal, cause horizontal machine tool to be difficult to realize high-precision crudy requirement.
Summary of the invention
The purpose of this utility model is to provide a kind of horizontal machine tool tailstock pressure means for correcting, realizes horizontal machine tool tailstock pressure is detected and proofreaied and correct.
The utility model solves the technical scheme that its technical problem adopts: a kind of horizontal machine tool tailstock pressure means for correcting is provided with main shaft test bar, dynamometer, tailstock test bar between headstock and tailstock.At machine tool head box spindle top place suit main shaft test bar, at the top suit tailstock of tailstock tool test bar.Two test bars are cylinder, and centre is provided with hanger, and one end is hollow centrum, respectively with spindle top and the top socket of tailstock tool.The other end of main shaft test bar processes a groove, and the other end of tailstock test bar processes a boss, and there is a round pool at boss center, for holding dynamometry steel ball.Dynamometer is Pressure gauge, interior pressing spring and display panel, consists of.
Method of operating: hollow centrum one end of main shaft test bar is hung to the socket at spindle top place, equally hollow centrum one end of tailstock test bar is hung in tailstock tool top place socket.Then ergographic front end face is sticked in the groove of main shaft test bar and hold, ergographic rear end face is met to the dynamometry steel ball in tailstock test bar boss.According to the load bearing requirements of lathe, start the top afterburning jacking of tailstock tool, observe the Pressure gauge numerical value on tailstock, meet the requirements of after afterburning value, observe ergographic numerical value change, record data, compare with the Pressure gauge numerical value on tailstock, can reach the object of correction.

The specific embodiment
As shown in Fig. 1-Fig. 3, at machine tool head box spindle top (1), locate to be set with main shaft test bar (2), at tailstock tool top (6), locate to be set with tailstock test bar (5); Middle dynamometer (3) is Pressure gauge, interior pressing spring and display panel, consists of; Main shaft test bar (2) is cylinder, and centre is provided with hanger (7), and one end is and the hollow centrum of spindle top (1) socket that the other end is a groove; Tailstock test bar (5) is cylinder, and centre is provided with hanger (7), and one end is and the hollow centrum of tailstock centre (6) socket that there is the boss of a round pool at other end Shi Yige center, has a dynamometry steel ball (4) in round pool.
Method of operating: through hanger (7), hollow centrum one end of main shaft test bar (2) is hung at spindle top (1) and locates socket, through hanger (7), hollow centrum one end of tailstock test bar (5) is hung at tailstock tool top (6) and locates socket equally.Then the front end face of dynamometer (3) is sticked in the groove of main shaft test bar (2) and hold, the rear end face of dynamometer (3) is met to the dynamometry steel ball (4) in tailstock test bar (5) boss.According to the load bearing requirements of lathe, start the afterburning jacking of tailstock tool top (6), observe the Pressure gauge numerical value on tailstock, meet the requirements of after afterburning value the numerical value change of observing dynamometer (3), record data, compare with the Pressure gauge numerical value on tailstock, can reach the object of correction.
Claims (1)
1. a horizontal machine tool tailstock pressure means for correcting, it is characterized in that: during dynamometry, between headstock and tailstock, be provided with main shaft test bar (2), dynamometer (3) and tailstock test bar (5), main shaft test bar (2) is cylinder, centre is provided with hanger (7), one end is and the hollow centrum of spindle top (1) socket that the other end is a groove; Dynamometer (3) is Pressure gauge, interior pressing spring and display panel, consists of; Tailstock test bar (5) is cylinder, and centre is provided with hanger (7), and one end is and the hollow centrum of tailstock tool top (6) socket that there is the boss of a round pool at other end Shi Yige center, has a dynamometry steel ball (4) in round pool.
