Description
Technical field
The present invention relates to bench drill, and in particular to a kind of device for eliminating bench drill and rotating abnormal sound.
Background technology
Existing bench drill is mostly that electrical machine belt pulley rotates drive primary shaft belt pulley rotation, and electrical machine belt pulley is mounted in motor
On axle, motor driven electrical machine belt pulley rotates, and electrical machine belt pulley with being provided with V-belt on primary shaft belt pulley, lean on by the rotation of primary shaft belt pulley
The transmission of V-belt and rotate, spline housing is provided with primary shaft belt pulley, spline housing is arranged on main shaft with main shaft cooperation, drill chuck again
On, main shaft is rotated and is moved up and down and be operated, because two parts of spline housing and main shaft are all metalworks, spline housing
While driving main shaft rotation, also to ensure the up and down motion of main shaft, coordinate so both relations are gaps, and processing request
Height, the gap between spline housing and main shaft are difficult to control, and abnormal sound will be produced when both rotate.
The content of the invention
Goal of the invention：It is an object of the invention to provide a kind of device for eliminating bench drill and rotating abnormal sound, solve spline housing and master
The problem of abnormal sound is produced when axle rotates.
Technical scheme：The device of the present invention for eliminating bench drill and rotating abnormal sound, including table drill main shaft and spline housing, it is described
Spline housing is enclosed on main shaft, working of plastics is socketed with the spline housing, and the working of plastics is machined with spline knot with spline housing
Structure.
Arrangement above, after coordinating main shaft and spline housing, main shaft first first contacts with the working of plastics in spline housing, allow main shaft with
Contact between spline housing is Elastic Contact, and when bench drill works, the elasticity change of working of plastics can be just utilized between spline housing and main shaft
Shape eliminates the gap between main shaft and spline housing, working of plastics is contacted with main shaft and carries out moment of torsion transmission, so as to changing original two
Rigid contact between metalwork and caused noise, this structure do not influence the transfer strength of whole machine, and and can eliminates bench drill and turned
Dynamic abnormal sound.
In order that spline housing and working of plastics firm contact, between the spline housing and working of plastics with the fixed method of positioning or
Interference fit.
In order that the fit clearance between spline housing and main spindle multiple spline reduces, the working of plastics spline structure is by the flower
Key is covered and working of plastics is installed together what post-processing formed, and mold injection machine-shaping can also be used to have the modeling of spline structure
Materials and parts.
In order to increase the service life, the material of the working of plastics is plasticity wear-resistant material.
In order to prevent that working of plastics runs out of spline housing after running at high speed for a long time, is provided with back-up ring between working of plastics and main shaft.
In order to which by together with working of plastics, spline housing and spindle mounted, the spline structure of the working of plastics and spline housing is
Internal spline, the internal spline are adapted with the external splines of main shaft.
It is segmental structure in the spline housing, one section is machined with spline structure, and one section is and the working of plastics outer wall in addition
Be adapted without spline structure.
In order to prevent working of plastics swing offset when being passed to its moment of torsion by main shaft, the working of plastics both sides are provided with convex
Ear, the spline housing are provided with the groove being adapted to the lug on one section without spline structure.
Beneficial effect：When the present invention makes the bench drill work, between spline housing and main shaft just can using the elastic deformation of working of plastics,
Spline housing and main shaft is run at high speed and load torque can be transmitted both during rotation imbalance, the transmission for not influenceing whole machine is strong
Degree, and can eliminate bench drill and rotate abnormal sound.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is cross-sectional structure schematic diagram of the present invention；
Fig. 3 is fractionation structural representation of the present invention.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As Figure 1-3, the device that bench drill rotates abnormal sound is eliminated, including table drill main shaft 1 and spline housing 2, spline housing 2 are enclosed on
On main shaft 1, pacify in an interference fit in spline housing 2
Equipped with working of plastics 3, and working of plastics 3 is machined with spline with spline housing 2, and the spline is first will be by spline housing 2 and modeling
What materials and parts 3 were process together again after being installed together, this processing mode produces certain modeling due to working of plastics self-characteristic
Property deformation, the working of plastics after process finishing in the splined section of spline housing occurs micro- resilience, the spline structure 4 of working of plastics with it is main
The fit clearance of the part of axle spline 5 is small, and the working of plastics with spline structure can also be processed into by mold injection, then will tool
Have in the working of plastics press-in spline housing of spline structure, when mold injection is processed, working of plastics inner spline groove is made a little bit smaller, so that
Main shaft spline sections coordinate with plastics female spline portion small―gap suture.Spline on spline housing 2 and working of plastics 3 is internal spline,
Want to be adapted to the external splines on main shaft 1, the both sides of working of plastics 3 are provided with lug 7, and two sections are divided into inside spline housing 2, and one section is machined with
Spline structure, the other end are provided with the groove 8 being adapted with working of plastics lug 7, and groove 8 is without spline structure, to cause working of plastics 3
It is assemblied in spline housing 2, so sets and cause when rotating shaft is inoperative, the splined section of main shaft 1 taps with the spline part of working of plastics 3
Touch, when spindle operation transmits moment of torsion, the splined section of main shaft 1 contacts with the splined section of spline housing 2, main shaft 1 and working of plastics 3 it
Between be provided with back-up ring 6, wherein, the material of working of plastics 3 is wear-resistant material, preferably nylon or strengthens nylon or polytetrafluoroethylene (PTFE) material
Matter.
Operation principle：It will be installed together after spline on main shaft and the spline fitted of spline housing, main shaft passes through working of plastics
With spline housing Elastic Contact, when bench drill works, main axis, when starting to transmit moment of torsion, because working of plastics inner spline groove is slightly less than
The width of the inner spline groove of spline housing, so, working of plastics is first passed to its torsion by main shaft external splines.Such as working of plastics stress
Displacement, just do not reach that we want when transmitting moment of torsion, main shaft external splines first coordinates with plastics internal spline, when moment of torsion is greatly to one
When given layer is spent, main shaft external splines coordinates the purpose for transmitting moment of torsion with the internal spline of steel part spline housing again, and spline housing and main shaft it
Between overcome the elastic deformation of working of plastics, spline housing is in contact with main shaft and carry out rigid of transmission load, do not influence whole machine
Transfer strength, and can eliminate bench drill and rotate abnormal sound.
