Abstract
The invention relates to a device for detecting dovetail guide rail parallelism. The device for detecting dovetail guide rail parallelism comprises a gauge main board, a dial gauge, a positioning block and a guide shaft. The gauge main board comprises an upper end surface and a lower end surface; a first groove and a first hole which penetrate through the lower end surface are formed in the upper end surface; the dial gauge comprises a gauge body and a connection rod; a measuring head is arranged on the gauge body; a steel ball is arranged on the end portion at one end of the connection rod, and the other end of the connection rod penetrates through the first hole and is connected with the gauge main board; a second hole penetrating left and right is further formed in the connection rod; the measuring head penetrates through the second hole; the positioning block is further provided with a locking bolt; a second groove is formed in the surface of the positioning block; one end of the gauge penetrates through the second groove; the guide shaft is connected with the positioning block through a screw. The measuring head, the steel ball and the guide shaft respectively make contact with two slopes of a dovetail guide rail, and the detection device can slide on the dial gauge to detect a numerical value on the dial gauge, and therefore the device for detecting dovetail guide rail parallelism is simple in operation procedure, obvious in detection result and small in error.
Description
Technical field
The present invention relates to a kind of detection dovetail guide depth of parallelism device, relate in particular to a kind of depth of parallelism device that detects dovetail guide two inclined-planes.
Background technology
Dovetail guide is as a kind of guide rail on lathe, ball-screw can drive worktable and slide on guide rail, in this process, the effect of ball screw is to change into rectilinear motion by rotatablely moving, so ball screw is widely used in various commercial units and exact instrument, ball screw is in the process that coordinates dovetail guide to use, utilize the guide rail guiding, realize location and drive by ball screw, the depth of parallelism to Liang inclined-plane, dovetail guide both sides has very high requirement, so the depth of parallelism on check Liang inclined-plane, dovetail guide both sides is very necessary.
Traditional method is all to place two sizeable steel balls on dovetail guide, with outside micrometer, measures the distance between two steel balls, and segmentation is measured.The maximum algebraic difference of measurement result is exactly the maximum difference of the dovetail guide depth of parallelism several times.When two slant rails are all parallel with check rod, two slant rails must be also parallel, therebetween the distance should equate everywhere, the degree of tightness of guarantee middle carriage on the total movement track is consistent, this method is all that manual measurement is easy to produce error, nor accurately.
Summary of the invention
Technical matters to be solved by this invention is: a kind of depth of parallelism device that dovetail is led that detects is provided, and described device can solve the whether parallel problem in dovetail guide two inclined-planes that detects, and also can make to measure more accurate simultaneously.
For addressing the above problem, technical scheme of the present invention is a kind of device that detects the dovetail guide depth of parallelism, comprise the cubing mainboard, connecting link, dial gauge, locating piece, the axis of guide, described cubing mainboard comprises plane and lower plane, described upper plane is provided with the kidney slot and the hole that penetrate into described lower plane, described connecting link is vertically placed, the connecting link upper end is connected with described cubing mainboard through described hole, the connecting link lower end is connected with described dial gauge screw, the lower surface of connecting link is provided with a steel ball, described locating piece is the block structure of upper end with bossing, the face that described locating piece is relative with described dial gauge is its medial surface, described bossing is through described kidney slot, on bossing, end face is provided with a clamping screw, the described axis of guide is connected with described locating piece screw, and the periphery of the axis of guide contacts with the locating piece medial surface, the described axis of guide and described dial gauge prop up respectively dovetail two ends guide rail.
Further, described axis of guide periphery is nearer than the dried up plane of locating piece bottom surface.
Compared with prior art, the present invention contacts with two inclined-planes of dovetail guide respectively with the axis of guide by dial gauge, by slip detection device on dovetail guide, swing numerical value on the dial gauge by pick-up unit detects, this device operating process is simple, and test effect is obvious and error is little.
