Abstract
Provided is a tool of a drilling machine for machining holes in a worm sector. The tool is mainly used for solving the problem that a pin hole, machined by a drilling machine, of a worm sector and a locating hole, machined by the drilling machine, of the worm section are poor in interchangeability. The tool is characterized in that a locating shaft (2) matched with a rotary shaft hole formed in the worm sector is arranged on a die plate (1), a locating block (3) is arranged at the portion, on one side, of the lower end of the die plate (1), a jackscrew (4) is longitudinally connected to the locating block (3), and drill bushings (5) are arranged in a pin hole and a locating hole formed in the die plate (1) respectively. The tool of the drilling machine for machining the holes in the worm sector has the advantage that the machined pin hole and the machined locating hole of the worm sector are good in interchangeability.
Description
Technical field
The utility model relates to a kind of drilling machine frock used, especially drilling machine processing worm sector hole tool.
Background technology
In railway freight-car field, worm sector is used widely at lorry.Worm sector is semicircle, has tooth and arc groove on cylindrical, has respectively shaft hole, pin-and-hole and locating hole on worm sector end face.Need to rule and the operation such as centering at drilling machine pin hole processing and locating hole, not only pin hole processing and locating hole efficiency are low, and are difficult to guarantee pitch-row between shaft hole, pin-and-hole and locating hole three holes, thereby reduce worm sector crudy, especially interchangeability, finally affects railway freight-car complete vehicle quality.
Summary of the invention
In order to solve drilling machine processing worm sector pin-and-hole and the poor problem of locating hole interchangeability.The utility model provides a kind of drilling machine processing worm sector hole tool.This drilling machine processing worm sector hole tool has processing worm sector pin-and-hole and the good feature of locating hole interchangeability.
The technical solution of the utility model is: this drilling machine processing worm sector hole tool comprises template.In template, have the locating shaft matching with worm sector upper spindle hole, there is locating piece template one side lower end, is longitudinally connected with jackscrew on locating piece, in the pin-and-hole in template and locating hole, has drill bushing.
The utlity model has following beneficial effect: this drilling machine processing worm sector hole tool has owing to adopting in template the locating shaft matching with worm sector upper spindle hole, there is locating piece template one side lower end, on locating piece, be longitudinally connected with jackscrew, in the pin-and-hole in template and locating hole, have the structure of drill bushing.Utilize pitch-row between the accurate positioning rotating shaft of locating shaft, jackscrew hole, pin-and-hole and locating hole three holes in template, guarantee pitch-row uniformity between shaft hole, pin-and-hole and locating hole three holes, thereby improve worm sector interchangeability.This drilling machine processing worm sector hole tool has processing worm sector pin-and-hole and the good feature of locating hole interchangeability thus.
accompanying drawing explanation:
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is Fig. 1 top views.
1-template in figure, 2-locating shaft, 3-locating piece, 4-jackscrew, 5-drill bushing.
the specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in accompanying drawing, this drilling machine processing worm sector hole tool comprises template 1.Template 1 shape and workpiece are approximate, in template 1, there is the locating shaft 2 matching with worm sector upper spindle hole, locating shaft 2 plays the role of positioning, there is locating piece 3 template 1 one side lower ends, on locating piece 3, be longitudinally connected with jackscrew 4, jackscrew 4 plays the role of positioning, and has in the pin-and-hole corresponding with pin-and-hole on worm sector end face and locating hole and locating hole and has drill bushing 5,5 protective actions of drill bushing in template 1.
When actual use, worm sector is placed on this drilling machine processing worm sector hole tool, locating shaft 2 in template 1 is placed in worm sector upper spindle hole, worm sector lower end leans against on jackscrew 4, then with pressing plate, worm sector is pressed on this drilling machine processing worm sector hole tool, finally pass through pin-and-hole and the locating hole on drill bushing 5 drilling worm sectors by drill bit, due to shaft hole positioning and drilling pin-and-hole and locating hole, so guarantee pitch-row between shaft hole, pin-and-hole and locating hole three holes, also just improve worm sector interchangeability.And easy for installation, improve processing worm sector efficiency.Be suitable for batch production.
Claims (1)
1. a drilling machine processing worm sector hole tool, comprise template (1), it is characterized in that: in template (1), have the locating shaft (2) matching with worm sector upper spindle hole, there is locating piece (3) template (1) one side lower end, on locating piece (3), be longitudinally connected with jackscrew (4), in the pin-and-hole in template (1) and locating hole, have drill bushing (5).
