Abstract
The invention discloses a quickly-replaced mechanism for a grinding rod of an internal grinding machine. The quickly-replaced mechanism comprises a belt wheel connecting shaft and a flexible shaft, wherein a bearing pedestal P207 and a bearing UC207 are arranged at the middle position of the belt wheel connecting shaft. The quickly-replaced mechanism is characterized in that: a coupler and a flexible shaft positioning shaft are arranged in front of the joint of the belt wheel connecting shaft and the flexible shaft; a bearing 6005 is sleeved outside the flexible shaft positioning shaft; and a movable tile frame and a damping cushion are arranged at the front end of the bearing 6005. By the improved quickly-replaced mechanism for the grinding rod, the internal grinding rod and the flexible shaft can be arranged on the machine and quickly replaced without occupying the time of centering and positioning on the machine, and the vibration of the internal grinding rod and the failure and the shutdown time of equipment can be reduced by additional damping performance, so that the production efficiency and the yield are improved.
Description
Technical field
The present invention relates to the interior grinding machine mill of cast tube bar positioner, the interior grinding machine mill bar quick-changing mechanism of mill bar in changing fast when especially relating to the cast tube that grinds different size in a kind of can the realization.
Background technology
Because the vibrations when work of interior grinding machine are bigger, and the mill bar positioner in the grinding machine does not have special damping, buffering function at present, phenomenons such as flexible axle fracture, the transposition of mill bar appear in grinding machine in making; Brought up interior grinding machine than higher fault rate; Simultaneously, when grinding the cast tube of different size in the needs, when carrying out grinding bar in the conversion or changing the flexible axle that ruptures; All need internally to grind during bar positions and look for; And these operations can only be carried out on interior grinding machine, have taken a large amount of production times, cause to yield poorly and inefficiency.
The present invention has carried out useful improvement in order to overcome above-mentioned defective.
Summary of the invention
It is big to the objective of the invention is to solve the vibration of existing mill bar, long etc. deficiency of replacing time on fault rate height and the machine, provide a kind of in grinding machine mill bar quick-changing mechanism.
To achieve these goals, the present invention adopts following technical scheme:
Grinding machine mill bar quick-changing mechanism in a kind of; Comprise belt pulley connecting axle and flexible axle; P207 bearing block and UC207 bearing are installed in the centre position of belt pulley connecting axle; Its special character is: shaft coupling and flexible axle locating shaft are installed before belt pulley connecting axle and flexible axle connecting portion, outside the flexible axle locating shaft, are socketed with 6005 bearings, the front end of said 6005 bearings is equipped with movable watt frame and beam;
Further, a described activity watt frame is divided into standing part and movable part, and wherein standing part is connected on the fixed head, internally grinds the bar position and positions, and the mill bar behind the position is fixed, tightly locked to movable part;
Further, described shaft coupling is the blossom type yielding coupling.
The present invention provides the quick-changing mechanism of the mill bar after the improvement; Mill bar and flexible axle machine are installed down in realizing, replacing does not take and looks for middle positioning time on the machine fast; And the vibrations of mill bar reduced equipment fault and downtime in subsidiary damping performance reduced, thereby enhanced productivity and output.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Embodiments of the invention are with reference to shown in Figure 2, and a kind of interior grinding machine mill bar quick-changing mechanism comprises belt pulley connecting axle and flexible axle; P207 bearing block 1 and UC207 bearing are installed in the centre position of belt pulley connecting axle, shaft coupling 4 and flexible axle locating shaft are installed before belt pulley connecting axle and flexible axle connecting portion, shaft coupling 4 is the blossom type yielding coupling; Outside the flexible axle locating shaft, be socketed with 6005 bearings 5; The front end of said 6005 bearings 5 is equipped with movable watt frame 6 and beam, and the activity of stating watt frame 6 is divided into standing part and movable part, and wherein standing part is connected on the fixed head; Internally mill bar position positions, and the mill bar behind the position is fixed, tightly locked to movable part.
The above embodiment has only been expressed one embodiment of the present invention, but can not therefore be interpreted as limitation of the scope of the invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the present invention's design, can also make some distortion and improvement, these all belong to protection scope of the present invention.
