SUMMERY OF THE UTILITY MODEL
The utility model aims at the above-mentioned problem that exists to current technique, provide a high-efficient grinding device of axle type work piece, the utility model aims to solve the technical problem how improve the efficiency of polishing.
The purpose of the utility model can be realized by the following technical proposal: the efficient grinding device for the shaft workpieces is characterized by comprising a base, a positioning cylinder, a rotary cylinder and a clamping assembly, wherein the positioning cylinder is fixed on the base, the rotary cylinder is rotatably connected outside the positioning cylinder, the clamping assembly comprises two grinding wheels, each grinding wheel is respectively connected through a connecting shaft, four first guide grooves are formed in the wall surface of the positioning cylinder, the end part of each connecting shaft is inserted into the corresponding first guide groove, four second guide grooves corresponding to the first guide grooves are formed in the inner wall of the rotary cylinder, the second guide grooves are parallel to the axis of the rotary cylinder, the first guide grooves are spirally distributed curved grooves, the first guide grooves are parallel to each other, a positioning groove formed by sinking the middle part of each grinding wheel is formed, and a clamping part for positioning the workpieces is formed between the two positioning grooves; the end part of the connecting shaft extends out of the first guide groove, and a return spring positioned in the second guide groove is connected between the connecting shaft and the rotary drum.
To treat that processing axle type work piece inserts between two grinding wheels, receive the pressure from top to bottom, the wheel of polishing moves down, under the effect of first guide way, the connecting axle is rotatory, the processing of polishing is carried out to the surface of work piece, receive the effect of second guide way, the connecting axle parallel reciprocates, realize the adjustment to the clearance between two constant head tanks through two wheel longitudinal separation of polishing, and receive reset spring's return under the effect, because under the same downforce effect, reset spring has the same restoring force, can order about two wheels of polishing and tend to on the coplanar, treat promptly that the work piece of processing compresses tightly.
Because the workpiece to be processed is pressed downwards, the grinding wheel is in a rotating state, so that no dead angle is left in grinding, the efficiency is extremely high, and the grinding wheel is used for derusting and rough grinding of the workpiece.
In the efficient grinding device for the shaft workpieces, two tensioning springs are connected between the two connecting shafts and are respectively positioned on two sides of the grinding wheel.
The tensioning spring can further enable the two grinding wheels to be close to each other, and clamping pre-tightening force on the workpiece is increased.
In the efficient grinding device for the shaft workpieces, the rotary drum is rotatably connected with the positioning cylinder through the bearing.

Fig. 3 is a schematic view of the structure of the connecting shaft and the grinding wheel.
In the figure, 1, a base; 2. a positioning cylinder; 3. a rotating drum; 4. grinding the wheel; 5. a connecting shaft; 6. a first guide groove; 7. a second guide groove; 8. a return spring; 9. the spring is tensioned.
Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in fig. 1, 2 and 3, the polishing device comprises a base 1, a positioning cylinder 2, a rotating cylinder 3 and a clamping assembly, wherein the positioning cylinder 2 is fixed on the base 1, the rotating cylinder 3 is rotatably connected outside the positioning cylinder 2, the clamping assembly comprises two polishing wheels 4, each polishing wheel 4 is respectively connected through a connecting shaft 5, four first guide grooves 6 are formed in the wall surface of the positioning cylinder 2, the end parts of the connecting shafts 5 are inserted into the corresponding first guide grooves 6, four second guide grooves 7 corresponding to the first guide grooves 6 are formed in the inner wall of the rotating cylinder 3, the second guide grooves 7 are parallel to the axis of the rotating cylinder 3, the first guide grooves 6 are spirally distributed curved grooves, the first guide grooves 6 are parallel to each other, a positioning groove formed by sinking in the middle part is formed in the polishing wheel 4, and a clamping part for positioning a workpiece is formed between the two positioning grooves; the end of the connecting shaft 5 extends out of the first guide groove 6, and a return spring 8 positioned in the second guide groove 7 is connected between the connecting shaft and the rotary drum 3.
To treat that processing axle type work piece inserts between two grinding wheel 4, receive the pressure from top to bottom, grinding wheel 4 moves down, under the effect of first guide way 6, connecting axle 5 is rotatory, the processing of polishing is carried out to the surface of work piece, receive the effect of second guide way 7, connecting axle 5 parallel reciprocates, realize the adjustment to clearance between two constant head tanks through two grinding wheel 4 longitudinal separation, and return under the effect that receives reset spring 8, because under the same overdraft effect, reset spring 8 has the same restoring force, can order about two grinding wheel 4 and tend to on the coplanar, treat promptly that the processing work piece compresses tightly.
Because the workpiece to be processed is pressed downwards, the grinding wheel 4 is in a rotating state, so that no dead angle is left in grinding, the efficiency is extremely high, and the grinding wheel is used for derusting and roughly grinding the workpiece.
Two tension springs 9 are connected between the two connecting shafts 5 and are respectively positioned at two sides of the grinding wheel 4. The tension spring 9 can further enable the two grinding wheels 4 to approach each other, and clamping pretightening force on the workpiece is increased.
The rotating drum 3 is rotatably connected with the positioning drum 2 through a bearing; the structure can also be as follows: the rotary drum cover is established outside the location section of thick bamboo, and the tip and the rotary drum of connecting axle are fixed continuous, and the rotary drum can be rotatory at location section of thick bamboo outer wall, also can longitudinal movement, and reset spring establishes between rotary drum and frame, and under this kind of structure, connecting axle longitudinal movement is more smooth and easy, the dead condition of card can not appear, nevertheless, to rough machining, former structure also can satisfy the demand, because during manual operation, the speed of treating processing axle type work piece longitudinal movement can not be too high, also can not receive great inhomogeneous external force.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
