Disclosed is a device favorable for determining concentricity of a power head main shaft and a theoretical machining hole. An installation threaded hole (1) used for installing each work station clamp is formed in a platform face of a circular rotary platform (3) of a linear reciprocating or circular rotary multi-station machine tool. Power heads (8) used for installing different machining cutters are respectively arranged on the different work stations arranged around the circular rotary platform. A detection tool seat (4) used for detection is installed at the center of the circular rotary platform. A cylindrical first detection rod (5) parallel to the platform face of the circular rotary platform is installed on the detection tool seat. A central line of the first detection rod (5) capable of rotating to different work stations along with the circular rotary platform is initially located in a scale mark reference line of the circular rotary platform, the distance between the first detection rod and the platform face of the circular rotary platform is equal to the distance between the center of each workpiece machining hole and the platform face of the circular rotary platform and the position is a theoretical machining position of the first work station. A second detection rod (7) capable of being vertically and laterally adjusted is respectively and horizontally arranged in each power head (8) used for installing the machining cutters. The device favorable for determining the concentricity of the power head main shaft and the theoretical machining hole has the advantages that a used detection tool is simple in structure, a special device is not needed for machining and assembly, a detection method is convenient and rapid, and detection precision is high.

Description

A kind of device of being convenient to determine dynamic head main spindle and theoretical machining hole axiality

Technical field

The utility model relates to linear reciprocation circular turntable formula multi-station machine tool processing technique field, mainly is the device of detection and definite dynamic head main spindle center line and theoretical machining hole axiality.

Background technology

The dynamic head main spindle center line of linear reciprocation circular turntable formula multi-station machine tool and workpiece add the theoretical machining hole axiality detection in man-hour does not for a long time have reliable way, normally adopt the indirect method of measurement, the distance of the theoretical hole of namely measuring processing work respectively to circular turntable table top, dynamic head main spindle to the circular turntable table top, whether see its difference in allowed band, if the overproof unit head of just adjusting is installed backing plate.For the lathe of single processing stations, this method is gathered effect substantially.But for multi-station machine tool, because many group anchor clamps use with the coupling in turn of unit head, satisfy the coaxial of anchor clamps and unit head of organizing by adjusting backing plate, adjustment complexity and difficulty are big more, and the machining accuracy of workpiece also can be a greater impact.

The utility model content

The purpose of this utility model provides a kind of and detects for linear reciprocation circular turntable formula multi-station machine tool dynamic head main spindle center line and theoretical machining hole axiality just in order to solve an above-mentioned difficult problem, and the device convenient and swift, that accuracy of detection is high.

The technical scheme that realizes the utility model purpose is as follows:

A kind of device of being convenient to determine dynamic head main spindle and theoretical machining hole axiality, circular turntable table top at linear reciprocation or circular turntable formula multi-station machine tool is processed with for the installation screw that each station anchor clamps is installed, and is respectively arranged with for the unit head that different process tools are installed at the different station around circular turntable; Be equipped with at the circular turntable center for detection of the cubing seat, at the cubing seat cylindrical first check rod parallel with the circular turntable table top is installed, can be initially in the calibration zero line of circular turntable with the center line that circular turntable turns to first check rod of different station, the distance of first check rod and circular turntable table top equals workpiece machining hole center to the distance of circular turntable table top, establishes the theoretical Working position of first station with this; In each unit head that process tool is installed, be separately installed with second check rod level and that can regulate up and down; Be adjusted to second check rod and first check rod coaxial at different stations successively, forward and the side direction of first check rod and second check rod on each station of difference centering, be the unit head position of this station of centering, the axiality of detection and definite dynamic head main spindle and theoretical machining hole.

The checkout gear that the utility model adopts is simple in structure, and processing and assembling need not Special Equipments.Detection method is convenient and swift, the accuracy of detection height.

Further set forth the utility model content below in conjunction with Figure of description.

The specific embodiment

As shown in Figure 1, employing the utility model detects and determines that the method for dynamic head main spindle and theoretical machining hole axiality is as follows:

Figure 2013200201162100002DEST_PATH_IMAGE001

Process the anchor clamps installation screw 1 of each station earlier at circular turntable 3 table tops of linear reciprocation or circular turntable formula multi-station machine tool, be used for installing the anchor clamps 2 of each station; Be respectively arranged with for the unit head 8 that different process tools are installed at the different station around circular turntable; Will for detection of cubing seat 4 be installed in circular turntable 3 centers, at cubing seat 4 cylindrical first check rod 5 parallel with the circular turntable table top is installed, the centerline of first check rod 5 is in the calibration zero line of circular turntable, first check rod 5 equals workpiece machining hole center to the distance of circular turntable table top with the distance of circular turntable table top, has established the theoretical Working position of first station thus; Second check rod 7 of first installation level in the unit head 8 of the other installation of circular turntable process tool, adjust the position up and down of unit head then, make second check rod 7 coaxial with first check rod 5, with this station of dial gauge 6 centerings i.e. forward and the side direction of first check rod 5 and second check rod 7 on first station; The forward of described first check rod and second check rod and side direction refer to two coordinate directions along the projection of check rod center line.As Fig. 2, shown in Figure 3, the cross section of second check rod 7 from be installed in unit head 8 is seen over, and vertical Y of correspondence was considered as the forward of check rod 7 when dial gauge detected, and the horizontal X of correspondence was considered as the side direction of check rod 7 when dial gauge detected.

Circular turntable is gone to i.e. second station of next station, the position that this moment, first check rod 5 was established, it namely is the i.e. theoretical Working position of the second station part of this station, only need second check rod 7 of this station and first check rod 5 are adjusted to coaxial, forward and the side direction of centering first check rod 5 and second check rod 7 get final product;

By that analogy, with second check rod 7 of all stations set by step

Described method is adjusted respectively, respectively forward and the side direction of first check rod 5 and second check rod 7 on each station of centering, and the unit head position of all stations that can centering is detected and the axiality of definite dynamic head main spindle and theoretical machining hole.

The cutter of installing on each station unit head of the utility model is finished corresponding processing content respectively, as milling face, the 3rd station borehole, the 4th station reaming, the 5th station tapping at first station loading and unloading, second station.During processing work, workpiece is installed in the anchor clamps, workpiece forwards a certain station to and just finishes this station and process accordingly.

The utility model is through verification experimental verification, and effect is better.
