Description
Technical field
The utility model belongs to a kind of dental handpiece car pin clamping device, especially relates to a kind of high speed movement main shaft.
Background technology
In existing dental handpiece car pin clamping device, the clamping plate that is used for the clampingc car pin is that the face that will act on mutually with spring and latch release shaft all is processed into the inclined-plane.And for this class widget of clamping plate two faces being processed into the inclined-plane, difficulty of processing is very big, and requirement on machining accuracy is higher, thereby also makes production cost increase.
The utility model content
The purpose of this utility model is to provide a kind of processing that is easy to, the high speed movement main shaft that production cost reduces.
According to an aspect of the present utility model, a kind of high speed movement main shaft is provided, comprise bearing shaft, be located at the positioner of an end in the bearing shaft and be located at the interior clamping device of bearing shaft, clamping device is located at the below of positioner, bearing shaft is provided with square through hole, square through hole comprises first through hole and second through hole, the axial width of first through hole is less than the width of second through hole, the lower surface of first through hole is higher than the lower surface of second through hole, clamping device comprises spring from top to bottom successively, top board, clamping plate and latch release shaft, clamping plate one end is located in first through hole, the other end is located in second through hole, the upper surface of clamping plate parallels with lower surface, clamping plate, top board, latch release shaft and clamping device are provided with the axis hole that is interconnected.Thereby, the swing space of clamping plate in second through hole is greater than the swing space in first through hole, by the inclined degree of top board to the effect control clamping plate of clamping plate, and then the control clamping device is to the clamp position of car pin, convenient adjustment to the clamping plate state, will not be processed as the inclined-plane by clamping plate, reduce difficulty of processing, thereby reduce processing cost.
In some embodiments, positioner holds up mouth to be fixed in the bearing shaft for holding up mouth.Thereby define the position of car pin in bearing shaft, be convenient to car pin location.
In some embodiments, top board is trapezoidal plate, and the upper surface of top board is that horizontal plane, lower surface are the inclined-plane, and the thickness that top board is positioned at second through hole, one side is positioned at the thickness of first through hole, one side greater than top board.The top board lower surface is that the inclined-plane makes and the swing of clamping plate when acting on clamping plate to make clamping plate tilt the car pin is clamped.
In some embodiments, the upper surface of first through hole and second through hole is located on the same sagittal plane of bearing shaft.
In some embodiments, top board is fixedlyed connected with latch release shaft.
Description of drawings
Fig. 1 is the structural representation of high speed movement main shaft of the present utility model;
Fig. 2 is the use status architecture schematic diagram of the high speed movement main shaft of the utility model one embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Referring to figs. 1 through Fig. 2: high speed movement main shaft, comprise bearing shaft 1, be located at the positioner 2 of an end in the bearing shaft 1 and be located at clamping device 3 in the bearing shaft 1, clamping device 3 is located at the below of positioner 2, and positioner 2 holds up mouth to be fixed in the bearing shaft 1 for holding up mouth.Bearing shaft 1 is provided with square through hole 4, square through hole 4 comprises first through hole 41 and second through hole 42, the axial width of first through hole 41 is less than the width of second through hole 42, the lower surface of first through hole 41 is higher than the lower surface of second through hole 42, clamping device 3 comprises spring 31 from top to bottom successively, top board 32, clamping plate 33 and latch release shaft 34, top board 32 is fixedlyed connected with latch release shaft 34, top board 32 connects by being weldingly connected with latch release shaft 34, clamping plate 33 1 ends are located in first through hole 41, the other end is located in second through hole 42, the upper surface of clamping plate 33 parallels with lower surface, clamping plate 33, top board 32, latch release shaft 34 and positioner 2 are provided with the axis hole 6 that is interconnected, and axis hole 6 matches with the car pin 5 that needs to clamp.
The upper surface of first through hole 41 and second through hole 42 is located on the same sagittal plane of bearing shaft 1.
High speed movement main shaft of the present utility model in use, press latch release shaft 34 or press and hold up mouth, make latch release shaft 34 relative bearing shaft 1 move upward, latch release shaft 34 promotes clamping plate 33, and the upper surface of clamping plate 33 contacts with the upper surface of through hole 4, and spring 31 is compressed, clamping plate 33 is left on the summit, inclined-plane of top board 32, thereby clamping plate 33 is the level of state under the effect of latch release shaft 34, and car pin 5 inserts in the high speed movement main shaft or takes out in high speed movement main shaft.
After car pin 5 inserted high speed movement main shaft, the active force that acts on the latch release shaft 34 was cancelled, and top board 32 moves downward under the effect of spring 31 bounces, utilized the inclined-plane to promote clamping plate 33, made clamping plate 33 tilt.When the upper surface of clamping plate 33 contacted with the upper surface of first through hole 41, clamping plate 33 kept heeling condition under the acting in conjunction of spring 31 and bearing shaft 1, thereby makes car pin 5 be in clamped condition.
Above-described only is preferred embodiment of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
