Abstract
The utility model discloses a round broaching tool with a guide sleeve relating to a cutting machining tool. The utility model provides a round broaching tool with the guide sleeve having advantages of flexible guiding function, simple machining, and strong replacement. The round broaching tool provided in the utility model is provided with a round broaching tool and a guide sleeve. The round broaching tool is provided with a guide sleeve installation part, a cutting part, and a rear guide part. The guide sleeve is disposed on the guide sleeve installation part of the round broaching tool, and the guide sleeve is circular-shaped and made of plastic materials, thereby the machining is simple, and the costs are low. The guide sleeve has strong replaceability, when the guide sleeve is machined after the machining for a plurality of times. The guide sleeve has no harm on the pipe materials by the guiding process. The guide sleeve can continuously move forwards, when the cutting machining is continued, and the guide sleeve can always guide the round broaching tool on the cutting part, thereby the machining error caused by the excessive eccentric phenomenon of the pipe materials and the round broaching tool can be prevented.
Description
Technical field
The utility model relates to a kind of cut instrument, especially relates to a kind of round broach of tape guide cover.
Background technology
Broaching tool is used very extensive aborning, can once accomplish the processing of thick, smart hole, has very high production efficiency.Coaxial for guaranteeing broaching tool with processed tubing center, often need broaching tool to have the guiding position.Existing broaching tool fairlead generally adopts integral manufacturing method, fairlead and the cutting integrated processing in position, and difficulty of processing is big.The material of its fairlead is consistent with cutting position materials used, if when beginning to cut, the centralized positioning of broaching tool is bad, and fairlead forms hard the contact and influences processing with processed tubing easily.
Summary of the invention
The purpose of the utility model is to provide a kind of fairlead to have the flexible guiding effect, and processing is simple, the round broach of the tape guide cover that replaceability is strong.
The utility model is provided with round broach and fairlead; Said round broach is provided with fairlead installation position, cutting position and guiding position, back, and fairlead is installed in the fairlead installation position of round broach.
Said fairlead can be loop configuration, and the fairlead installation position of the internal diameter of said loop configuration and round broach is a tight fit, and the external diameter of said loop configuration is than the little 0.1mm of external diameter of first tooth of cutting position of round broach; Said fairlead can adopt the plastic material fairlead.
Said fairlead is installed in the fairlead installation position of round broach with friction tight mode.
During use, fairlead is installed on the fairlead installation position of round broach, after processed tubing is passed at the fairlead position that will have a round broach of fairlead, with the round broach clamping on the straight line shifting axle of broaching machine; Processed tubing clamping is on the rotating shaft of broaching machine, and when the cutting beginning, rotating shaft drives processed tubing rotation, and straight line shifting axle drive round broach moves, and the two cooperation forms cutting.Along with constantly carrying out of cut, fairlead constantly moves, and always in the place ahead channeling conduct at the cutting position of round broach, prevents excessively off-centre and cause mismachining tolerance of tubing and round broach.
Compare with existing round broach, the utlity model has following outstanding advantage:
1) fairlead of the utility model is a loop configuration, adopts plastic material to process, and it is low to process simple cost, and when needing replacement after the processing repeatedly, replaceability is strong.
2) fairlead of the utility model adopts plastic material to process, and in the guiding process, can not damage tubing.
3) along with constantly the carrying out of cut, fairlead constantly moves, and in the place ahead channeling conduct at the cutting position of round broach, prevents that the excessive off-centre of tubing and round broach from causing mismachining tolerance always.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The view that Fig. 2 works on broaching machine for the utility model embodiment.
Fig. 3 is the round broach of the utility model embodiment and the guiding sketch map of fairlead.
In Fig. 1～3, respectively be labeled as: the back guiding position of the fairlead installation position of 1 round broach, the cutting position of 2 round broach, 3 round broach, 4 fairleads, 5 broaching machine straight line shifting axles, 6 broaching machine rotating shafts, 7 processed tubing.
The specific embodiment
Below through embodiment and combine accompanying drawing that the utility model is described further.
Shown in Fig. 1～3, be provided with round broach and fairlead 4 in the present embodiment; Said round broach is provided with fairlead installation position 1, cutting position 2 and guiding position 3, back, and fairlead 4 is installed in the fairlead installation position 1 of round broach with friction tight mode.
Said fairlead 4 is a loop configuration, and the fairlead installation position 1 of the internal diameter of said loop configuration and round broach is a tight fit, and the external diameter of said loop configuration is than the little 0.1mm of external diameter of cutting position 2 first teeth of round broach; Said fairlead 4 adopts the plastic material fairlead.
The internal diameter of processed tubing 7 is 19.5mm among the embodiment, and the external diameter of fairlead 4 is 19.2mm.
Shown in Fig. 2 and 3, in the implementation process of present embodiment, fairlead 4 is installed on the round broach; After passing processed tubing 7 to the fairlead installation position 1 of the round broach that has fairlead 4, with the round broach clamping on the straight line shifting axle 5 of broaching machine; Processed tubing 7 clampings are on the rotating shaft 6 of broaching machine.When the cutting beginning, processed tubing 7 rotations of broaching machine rotating shaft 6 drives, and broaching machine straight line shifting axle 5 drive round broach move, the two cooperates to form cuts.Along with constantly carrying out of cut, fairlead 4 constantly moves forward, and is cutting the place ahead channeling conduct at position 2 always, prevents that processed tubing 7 and round broach are excessively eccentric and causes mismachining tolerance, has guaranteed machining accuracy.
