Description
Technical field
The utility model relates to a kind of wheel frame, and more particularly, it relates to a kind of grinding machine wheel frame of quick position main shaft.
Background technology
Grinding machine utilizes grinding tool to carry out the lathe of grinding to surface of the work.Wherein, centerless grinder, it is the class grinding machine not needing to adopt the axle center of workpiece and implement grinding, by abrasive grinding wheel, guide wheel and work support three mechanisms are formed, the actual work of serving as grinding of abrasive grinding wheel, work support plays a part when grinding to support workpiece, guide wheel then controls the rotation of workpiece, and make workpiece generation feed velocity, can find out that guide wheel plays important effect in centerless grinder, and guide wheel is normal and workpiece collision friction easily damages, thus how to make guide wheel fast installing/dismounting be also be the standard of a judge grinding machine quality.
In prior art, a kind of guide wheel bracing or strutting arrangement of centerless grinder is disclosed at the application number Chinese patent that is CN200620103547.5, it arranges bracing or strutting arrangement at guide wheel and the straight key of transmission mechanism, mainly guide wheel shaft grows guide wheel front end face, the guide wheel shaft of guide wheel front end is arranged and makes device, this bracing or strutting arrangement by making seat, the sliding bearing be arranged in supporting seat, end cap and lubricating structure form, guide wheel shaft leading section coordinates with sliding bearing.Although this guide wheel bracing or strutting arrangement improves rigidity and the bearing capacity of guide wheel shaft, guide wheel is made to rotate steadily, improve the machining accuracy of part, but main shaft needs to be set in wheel frame, then by cover plate, main shaft is fixed in wheel frame, then main shaft installation site is fixed by the bolt be fixed on square cover plate, main shaft rotates in circular main shaft mounting groove, easily make erosion of wall, circular hole and the main shaft of lid create gap, main shaft installation site easily produces deviation, causes grinding machine grinding work-piece precision not high.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide one to facilitate main shaft to install, and realizes the grinding machine wheel frame of quick position main shaft.
For achieving the above object, the utility model provides following technical scheme: a kind of grinding machine wheel frame of quick position main shaft, include wheel frame main body, described wheel frame entire body is rectangular structure, one end along the long side direction of described wheel frame main body is connected with protuberance, described protuberance offers the groove for holding main shaft, and the through whole wheel frame main body of described groove, described wheel frame main body offers guide wheel chamber towards the side of described protuberance.
Adopt the wheel frame of this structure, when guide wheel causes workpiece grinding precision not high, when needing to change dismounting, only main shaft directly need be placed on semicircular groove, then buckle lid and just can complete replacing fast and easily, prevent the wheel frame of full circle in the past, collar bush need be allowed to be located in circular main shaft mounting groove, be difficult to dismantle and the not high problem of installation accuracy.
As preferably: described wheel frame main body upper end offers penetrating groove, and described guide wheel cavity wall is connected with reinforcement towards the end face of penetrating groove.
Adopt the wheel frame of this structure, the penetrating slot of setting, in the upper end in guide wheel chamber, facilitate the finishing of guide wheel, and reinforcement enhances the intensity of wheel frame main body, and the guide wheel dresser of cavity upper end can be fixed in wheel frame main body stably.
As improvement: described wheel frame main body offers cavity relative to the end face being provided with described protuberance.
Adopt the wheel frame of this structure, alleviate the weight of wheel frame main body, more convenient detachable maintaining wheel frame, and improve the radiating effect of wheel frame.
Compared with prior art, the utility model has the advantage of: by wheel frame is arranged to semicircular structure, thus solve the collar bush existed in prior art and be located in wheel frame, the problem of the secondary assembling and positioning degree of accuracy, change was fixed in wheel frame by lid by main shaft in the past, circular hole and the main shaft of lid are not concentric, main shaft installation site easily produces deviation, cause the problem that grinding machine grinding work-piece precision is not high, can allow grinding machine worker more quick changing main-spindle accurately during maintenance, during grinding, obtain workpiece more accurately.

Detailed description of the invention
Referring to figs. 1 through Fig. 4, the grinding machine wheel frame embodiment of the utility model quick position main shaft is described further.
A kind of grinding machine wheel frame of quick position main shaft, include wheel frame main body 1, wherein, wheel frame main body 1 entirety is in rectangular structure, one end along the long side direction of wheel frame main body 1 is connected with protuberance 2, protuberance 2 offers the semi-circular recesses 111 for holding main shaft, the through whole wheel frame main body 1 of groove 111, wheel frame main body 1 offers guide wheel chamber 112 towards the side of protuberance 2, guide wheel chamber 112 cuts off wheel frame main body 1 and for installing guide wheel, when guide wheel causes workpiece grinding precision not high, when needing to change dismounting, only main shaft directly need be placed on semicircular groove 111, then buckle lid and just can complete replacing fast and easily, prevent the wheel frame of full circle in the past, collar bush need be allowed to be located in circular main shaft mounting groove, be difficult to dismantle and the not high problem of installation accuracy.Wheel frame main body 1 offers cavity 115 relative to the end face being provided with protuberance 2, alleviates the weight of wheel frame main body, more convenient detachable maintaining wheel frame, and improves the radiating effect of wheel frame.
Wheel frame main body 1 upper end offers penetrating groove 113, guide wheel chamber 112 inwall is connected with reinforcement 114 towards the end face of penetrating groove 113, the penetrating groove 113 arranged is positioned at the upper end of cavity, facilitate the finishing of guide wheel, and reinforcement 114 enhances the intensity of wheel frame main body 1, the guide wheel dresser of upper end, guide wheel chamber 112 can be fixed in wheel frame main body 1 stably.
The utility model is by being arranged to semicircular structure by wheel frame, thus solve the collar bush existed in prior art and be located in wheel frame, the problem of the secondary assembling and positioning degree of accuracy, change was fixed in wheel frame by lid by main shaft in the past, circular hole and the main shaft of lid are not concentric, main shaft installation site easily produces deviation, cause the problem that grinding machine grinding work-piece precision is not high, can allow grinding machine worker more quick changing main-spindle accurately during maintenance, during grinding, obtain workpiece more accurately.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
