Abstract

The utility model discloses a rolling shaft drilling tooling, and aims to provide a rolling shaft drilling tooling which is fast in processing speed and high in precision and efficiency. The rolling shaft drilling tooling comprises a work bench surface with the bottom provided with a linear guide track, the work bench surface is provided with drilling dies which are in I-shaped arrangement, the number of the drilling dies is identical to that of drilling holes of a rolling shaft, a center distance between drilling sleeves among the drilling dies is identical to a corresponding pitch of the rolling shaft, the drilling dies are provided with fast clamping devices for the rolling shaft, and the transverse left end or right end of each drill die is provided with a positioning device for end surfaces of the rolling shaft so as to axially position the rolling shaft. The rolling shaft drilling tooling has the advantages of convenient operation, fast processing speed, accurate positioning and high precision.

Description

The roller bearing drilling tool

Technical field

The utility model relates to the frock of axial workpiece in boring, especially a kind of roller bearing drilling tool.

Background technology

Roller bearing is a strength member on the printer, and it is not only elongated, and with one side a plurality of holes is being arranged on slender axles, and that the position degree in hole has is very as shown in Figure 1 high.Be difficult to reach required precision as the processing of location, hole one by one, and the efficient of processing is low, the cost height.

Summary of the invention

The purpose of this utility model provides that a kind of process velocity is fast, precision and the high roller bearing drilling tool of efficient.

In order to achieve the above object, the technical scheme of roller bearing drilling tool is: it comprises that the work top of line slideway is arranged at the bottom, word order and the identical drill jig of roller bearing boring number are installed on the work top, the centre-to-centre spacing of drill bushing is identical with the corresponding pitch-row of roller bearing between each drill jig, on drill jig, be provided with fast fixture to roller bearing, at the end face positioner that the horizontal left end of drill jig or right-hand member are provided with roller bearing, implement axial location to roller bearing.

Roller bearing drilling tool according to said structure is made is adding man-hour, meets the requirements to the position in first hole as long as adjust end face that the end face positioner makes roller bearing.Under the situation that bit location does not move, by the mobile working table top, under the guiding of each drill jig,, hole one by one by one-time positioning, all processing is complete with the hole on the whole roller bearing.It has, and easy to operate, process velocity is fast, the location is correct, advantage of high precision.

The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing.

Fig. 2, Fig. 3 are the structural representations of roller bearing drilling tool.As seen from the figure, it comprises that the work top 2 of line slideway 1 is arranged at the bottom, word order and identical 3 drill jigs 5 (3 drill jigs can be made into one) of roller bearing 3 borings, 4 numbers are installed on the work top 2, the centre-to-centre spacing of 5 drill bushings 6 of each drill jig is identical with roller bearing 3 corresponding holes 4 distances, on drill jig 5, be provided with fast fixture 7 to roller bearing 3, at the end face positioner 8 that the horizontal left end of drill jig 5 or right-hand member are provided with roller bearing 3, implement axial location to roller bearing 3.

Adding man-hour, meeting the requirements to the position in first hole 4 as long as adjust end face that end face positioner 7 makes roller bearing 3.Under the mobile situation in drill bit 9 positions, by mobile working table top 2, under the guiding of each drill jig 5,, hole one by one as Fig. 4, shown in Figure 5 by one-time positioning, all processing is complete with the hole on the whole roller bearing 34.

Claims

1. roller bearing drilling tool, it is characterized in that it comprises that the work top of line slideway is arranged at the bottom, word order and the identical drill jig of roller bearing boring number are installed on the work top, the centre-to-centre spacing of drill bushing is identical with the corresponding pitch-row of roller bearing between each drill jig, on drill jig, be provided with fast fixture to roller bearing, at the end face positioner that the horizontal left end of drill jig or right-hand member are provided with roller bearing, implement axial location to roller bearing.
