Description
Technical field
The utility model relates to auto parts and components manufacture fields, more particularly, to a kind of fixture for sprocket wheel broaching tool.
Background technique
Broaching tool is the forming tool for broaching.Have multiple rows of cutter tooth on tool surface, each size and shape for arranging cutter tooth from
Incision end is successively increased and is changed to cutting out end.When broaching tool makees broaching movement, each cutter tooth just cuts certain thickness from workpiece
The metal of degree finally obtains required size and shape.Broaching tool be usually used in batch in mass production process circular hole, spline
Hole, keyway, plane and forming surface etc., productivity is very high.
The clamp structure for being currently used for sprocket wheel broaching tool is complicated, and clamping is inconvenient, is not easy to worker operation.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of fixtures for sprocket wheel broaching tool.
Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of fixture for sprocket wheel broaching tool,
Including bottom plate and clamping component, the bottom plate is equipped with microscope carrier, and the microscope carrier is equipped with cylindrical positioning table, described
Positioning table be equipped with positioning spline, the clamping component includes compact heap, pushing block and push rod, and the compact heap is fixed on fixed
On the platform of position, sliding slot is equipped in the compact heap, the pushing block is movably arranged in sliding slot, and the push rod and compact heap are living
Dynamic connection, one end of the push rod are fixedly connected with pushing block tail portion, and the pushing block head is equipped with to be adapted with sprocket indentations
Two card bases, two card base interval predetermined angulars, the push rod and pushing block link, and the push rod can push
Block is close to positioning table, and retention bead is equipped in the sliding slot, and the push rod is equipped with the limit being adapted with retention bead
Position slot.
It is further improved as the utility model, the push rod is threadedly coupled with compact heap.
It is further improved as the utility model, the angle being spaced between two card bases is equal to four teeth of sprocket wheel
The sum of angle of slot.
It is further improved as the utility model, the angular range being spaced between two card bases is 56 ° ~ 58 °.
Compared with prior art, the utility model has the advantage of simple structure and reasonable designs, facilitate worker operation.Letter
For list, sprocket wheel is inserted in positioning table, push rod is screwed into compact heap, push rod pushes pushing block to positioning table, until on pushing block
Card base is caught in the tooth socket of sprocket wheel, at this point, retention bead is caught in the limiting slot of push rod, prevents sprocket wheel in processing, push rod returns
It moves back, it is ensured that will not be loosened in sprocket wheel process.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model one；
Fig. 2 is the utility model structure diagram two；
Fig. 3 is the utility model pushing block structural schematic diagram.
Specific embodiment

As shown in Figure 1 to Figure 3: a kind of fixture for sprocket wheel broaching tool, including bottom plate 1 and clamping component, bottom plate 1 are equipped with
Microscope carrier 2, microscope carrier 2 be equipped with cylindrical positioning table 3, positioning table 3 be equipped with positioning spline 4, clamping component include compact heap 5,
Pushing block 6 and push rod 7, compact heap 5 is fixed on the positioning table (3), and sliding slot 8 is equipped in compact heap 5, and pushing block 6 is movably arranged on sliding slot 8
Interior, push rod 7 is flexibly connected with compact heap 5, and one end of push rod 7 is fixedly connected with 6 tail portion of pushing block, and 6 head of pushing block is equipped with and sprocket wheel
Two adaptable card bases 9 of 111 tooth sockets 112, two card bases 9 are spaced predetermined angular, and push rod 7 and pushing block 6 link, and push rod 7 can push away
Dynamic pushing block 6 is close to positioning table 3, and retention bead 10 is equipped in sliding slot 8, and push rod 7 is equipped with the limit being adapted with retention bead 10
Position slot.
Push rod 7 is threadedly coupled with compact heap 5.
The angle being spaced between two card bases 9 is equal to the sum of the angle of 111 4 tooth sockets 112 of sprocket wheel.
The angular range being spaced between two card bases 9 is 56 ° ~ 58 °.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
