Abstract
The invention discloses a tricycle brake axle groove milling positioning device in order to improve brake axle groove milling efficiency. The tricycle brake axle groove milling positioning device comprises a clamp body. A fixed V-shaped block and a movable V-shaped block are arranged on the clamp body in pairs. V-shaped grooves in the fixed V-shaped block and the movable V-shaped block are arranged in a relative-mirror mode. The movable V-shaped block is in sliding linkage with a guiding rod. The guiding rod is fixedly arranged on the clamp body. A driving portion of the movable V-shaped block abuts against a cam. The cam with a handle is in rotating linkage with the clamp body. When the cam is rotated, the section surface of the cam pushes and extrudes the movable V-shaped block to move in the axial direction of the guiding rod. A supporting sleeve for positioning a brake axle is arranged between the V-shaped grooves in the fixed V-shaped block and the movable V-shaped block. A feeler block with an open slot is in linkage with the position, corresponding to the trajectory of a milling cutter, of the clamp body. The feeler block is in linkage with the clamp body and is adjusted to be in place in advance. Tool setting can be conveniently carried out before groove milling, the end of a workpiece is positioned on the supporting sleeve and clamped by the fixed V-shaped block and the movable V-shaped block, and clamping force is applied after the cam is rotated.
Description
Technical field
The present invention relates to a kind of positioner.
Background technology
The brake disc of the brake of tricycle is provided with a pair shoe brake assembly, and two shoe brake assembly abutting joints on the disc brake rotor, produce frictional force when the inner surface of brake drum contacts with the friction plate on shoe brake assembly thus realize braking.Brake axle is filled between two shoe brake assemblies, the footstalk of brake axle respectively with the end thereof contacts of two brake-shoes, brake axle is connected with brake arm again, the other end of brake arm is connected with bracing wire, pull bracing wire, brake axle produces moment of torsion, and two brake-shoes are expanded outwardly, thus friction plate is contacted with brake drum produce frictional force, realize brake.
Fixture installs on lathe, before processing, still needs and carries out the tool setting of fixture, makes cutter opposed jaw setting element be in tram.The method of tool setting has three kinds usually: Test-cut met tool setting, adjusting method tool setting, with exemplar or tool setting device tool setting.No matter adopt which kind of presetting cutter method, all relate to base point for checking cutting tool and cutter-aligndimension.Normally using the locating surface on the setting element overlapped with work year positioning datum as base point for checking cutting tool, to reduce the error that transformation of criterion brings.The cutter-aligndimension of fraise jig be from base point for checking cutting tool to Tool in Cutting surface position dimension, and feeler block position dimension differs from a clearance gauge thickness.
The efficiency of tool setting can affect the progress of whole processing technology, and the tool setting efficiency how in lifting clamp is that one of ordinary skill in the art are devoted to perfect problem always.
Summary of the invention
The invention is intended to provide a kind of brake axle of tricycle groove milling positioner, to improve the working (machining) efficiency of brake axle groove milling.
Brake axle of tricycle groove milling positioner in this programme, comprise clamp body, clamp body is provided with paired determines vee-block and dynamic vee-block, and the V-shaped groove opposing mirror image determined on vee-block and dynamic vee-block is arranged, dynamic vee-block is slidably connected on guide post, and guide post is fixedly arranged on clamp body.Drive division and the cam of dynamic vee-block offset, cam with handle is rotatably connected on clamp body, during rotating cam, dynamic vee-block moving axially along guide post is pushed in the shape face of cam, determine the splicing sleeve be also provided with between the V-shaped groove on vee-block and dynamic vee-block for position brake axle, on clamp body, the position of corresponding milling cutter track is connected with the feeler block of band open slot.
Feeler block is connected on clamp body, and pre-debugging puts in place, can carry out cutter tool setting easily before groove milling, the end of workpiece is positioned on splicing sleeve, and by determining vee-block and dynamic vee-block is clamped, rotate after-applied clamping force by cam, the efficiency of tool setting and mounting or dismounting all ten/high.
Further, feeler block is detachably connected on clamp body.The feeler block of different size can be used instead according to the difference of processing object.
Further, in the screwed hole of splicing sleeve thread connection on clamp body, its axial displacement can be adjusted easily.
Further, described guide post is symmetricly set on V-shaped groove both sides, guide post is arranged with the stage clip withstanding on and determine vee-block and dynamic vee-block opposite face.Two guide posts can ensure the having stable behavior of dynamic vee-block, and it is more convenient that stage clip can make workpiece dismantle.
Accompanying drawing explanation
Fig. 1 is the cross-sectional schematic of the embodiment of the present invention.
Fig. 2 is the schematic top plan view of the embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: determine V shape block 1, dynamic V shape block 2, cam 3, feeler block 4, clamp body 5, positioning key 6, splicing sleeve 7.
Embodiment is substantially as shown in accompanying drawing 1,2: clamp body 5 is positioned on work top by positioning key 6, clamp body is provided with paired determines vee-block 1 and dynamic vee-block 2, determine vee-block fixedly to lean against on clamp body, the V-shaped groove opposing mirror image determined on vee-block and dynamic vee-block is arranged, determine vee-block is connected with two guide posts that level is stretched out, dynamic vee-block is slidably connected on guide post, and described guide post is symmetricly set on V-shaped groove both sides, guide post is determined the stage clip being provided with reset between vee-block and dynamic vee-block.
The projection of dynamic vee-block right is drive division, and cam 3 and dynamic vee-block that clamp body can horizontally rotate offset, and cam is fixed with and is convenient to hand-held handle, during rotating cam, dynamic vee-block moving axially along guide post is pushed in the shape face of cam.
To determine between the V-shaped groove on vee-block and dynamic vee-block below and be provided with a through screwed hole, in screwed hole, thread connection has the splicing sleeve 7 for position brake axle, and workpiece and splicing sleeve should keep coaxial.On clamp body, the position of corresponding milling cutter track is connected with the feeler block 4 of band open slot.The C font of feeler block substantially in opening upwards, feeler block is connected in the upper left side of clamp body.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
