Embodiment Construction

[0013] In order to make the content of the present invention more clearly understood, the present invention will be further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0014] Such as figure 1 As shown, a radial drilling device for shaft sleeve parts, which includes a clamp body 20, a drilling module assembly, a positioning mandrel 7, a positioning mechanism and an indexing mechanism for shaft sleeve parts, and the positioning mandrel 7 is rotatable Supported on the clamp body 20, the bushing type parts positioning mechanism is installed on the positioning mandrel 7 so that the bushing type parts 22 are locked on the positioning mandrel 7, and the drilling mold assembly is installed on the top of the clamping body 20 for alignment. Shaft sleeve parts 22 are drilled. The indexing mechanism includes positioning pin 4, indexing plate 3, indexing pin 18 and return spring. Indexing plate 3 is set on the positioning man...

Abstract

The invention discloses a radial drilling device for shaft sleeve parts. The radial drilling device comprises a clamp, a drilling jig component, a positioning mandrel, a shaft sleeve part positioning mechanism and an indexing mechanism, the positioning mandrel is supported on the clamp rotatably, the shaft sleeve part positioning mechanism is mounted on the positioning mandrel so as to lock one shaft sleeve part on the positioning mandrel, the drilling rig component is mounted at the top end of the clamp so as to be used for drilling the shaft sleeve part, the indexing mechanism comprises a positioning pin, an indexing plate, an indexing pin and a return spring, the indexing plate sleeves the positioning mandrel, a plurality of indexing grooves and a plurality of positioning holes corresponding to to-be-drilled positions of the shaft sleeve part are formed in the indexing plate, each indexing groove is of an internal arc half-concave sphere structure, the front end of the indexing pin is provided with an arc ball head matched with the indexing grooves, one end of the return spring butts against the clamp, and the other end of the same butts against the indexing pin. By the radial drilling device which is simple and convenient to operate, high positioning accuracy in drilling can be achieved, and radial multi-hole indexing machining is easy to realize.

Description

technical field [0001] The invention relates to a radial drilling device for shaft sleeve parts. Background technique [0002] At present, the existing various radial porous drilling devices are generally complex in structure. The common existing technical solutions are: indexing positioning mechanism or cylindrical cam indexing mechanism, ratchet mechanism, generally large in size and complex in structure. Manufacturing costs are high. [0003] Common radial porous positioning methods include: steel ball positioning, cylindrical pin positioning, etc. Steel ball positioning is very unreliable due to the shallow depth of the cone pit; the common cylindrical pin positioning cannot compensate the influence of the fit clearance between the indexing pairs on the indexing accuracy. Contents of the invention [0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art, and provide a radial drilling device for shaft sleeve part...
