Abstract
The invention discloses an adjustable poking block for outer circle grinding of a drill bit, and aims to solve the problems of high probability of damage of an existing chuck and non-adjustable clamping size of the chuck. The adjustable poking block for outer circle grinding of the drill bit comprises a rotary poking disc and two groups of adjustable poking block structures of the same structure which are symmetrically arranged along the radial direction of the rotary poking disc, wherein a taper through hole for a tip of a headstock to pass through is formed in the center of the rotary poking disc along the axis direction; each adjustable poking block structure comprises a poking block body, an adjustable clamping block and a screw; the poking block bodies are fixedly arranged on a disc surface of the rotary poking disc and are provided with threaded holes; strip-shaped adjusting holes are formed along the radial directions of the adjustable clamping blocks; screw stems of the screws can pass through the adjusting holes to form threaded connection with the poking block bodies; the heads of the screws can be used for tightly pressing the outer end faces of the adjustable clamping blocks.
Description
Technical field
The present invention relates to the fixture of cylindrical grinding, be specifically related to the adjustable shifting block of a kind of bit grinding cylindrical.
Background technology
Drill bit is used to drilling on solid material and goes out through hole or blind hole, and can to the cutter of existing hole reaming.Drill bit end has taper shank.Drill bit blade cylindrical grinding is comprised to the processing of drill bit.In prior art, during drill bit blade cylindrical grinding, adopt the chuck of iron sheet opening to carry out the taper shank of clamping drilling bit, then drive bit to grind cylindrical by driving lever.There is following problem in the mode of above-mentioned employing grips taper shank: 1. due to the insufficient clamping force of chuck, and grinding impulsive force is comparatively large, and when producing in a large number, chuck very easily damages; 2. the size of grips is non-adjustable, and a kind of chuck can only clamp a kind of drill bit of size taper shank, and the taper shank many sizes of drill bit, therefore, adopt grips, not economical and practical.
Summary of the invention
The invention provides the adjustable shifting block of a kind of bit grinding cylindrical, be easy to damage to solve existing chuck, the nonadjustable problem of grips size.
The present invention program is as follows: the adjustable shifting block of bit grinding cylindrical, comprise the adjustable block-dialing structure that revolving dial is identical with the two groups of structures arranged along revolving dial radial symmetric, have can supply the top tapering through hole passed of headstock in described revolving dial central axial direction, described adjustable block-dialing structure comprises shifting block body, adjustable grip block and screw, shifting block body is fixed in the card of revolving dial, shifting block body has screwed hole, radial direction along adjustable grip block has the adjustment hole of strip, the screw rod of screw can be threaded with shifting block body through adjustment hole, the head of screw can compress the outer face of adjustable grip block.
This programme operation principle is as follows: revolving dial is connected on lathe, the taper shank of drill bit is inserted between two groups of adjustable grip blocks, and hold by the headstock of lathe is top, regulate the taper shank of the distance clamping drill bit between two groups of adjustable grip blocks, then the screw rod of screw is made to be threaded with shifting block body through adjustment hole, the head of screw compresses the outer face of adjustable grip block simultaneously, with fixing adjustable grip block.
The present invention carrys out the taper shank of clamping drilling bit by adjustable grip block, adjustable grip block good rigidly, wear-resisting durable, produces in enormous quantities also not fragile; The present invention is by regulating the distance between two groups of adjustable grip blocks, and the drill taper shank of clamping different size, is applicable in enormous quantities, multi items, similar-type products processing.
Further, the inner of described shifting block body has boss, and the outer face of boss is provided with guide groove, and described screwed hole is arranged on the bottom land of guide groove, and adjustable grip block is arranged in guide groove.Guide groove, when adjustable grip block moves, has the effect of guiding, makes the clip position of adjustable grip block more accurate.
Further, the insertion that conveniently headstock is top, and make that headstock is top holds drill taper shank, the inner of adjustable grip block has the identical taper face of tapering top with headstock.
Further, shifting block body is fixed in the card of revolving dial by trip bolt, and structure is simple, for convenience detach.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention;
Fig. 2 is the right view of Fig. 1.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
As depicted in figs. 1 and 2, the Reference numeral in accompanying drawing comprises revolving dial 1; Shifting block body 2; Adjustable grip block 3; Adjustment hole 31; Trip bolt 4; Screw 5; Headstock top 6; Drill taper shank 7.
As shown in Figure 1, the adjustable shifting block of the present embodiment bit grinding cylindrical, comprise the adjustable block-dialing structure that revolving dial 1 is identical with the two groups of structures arranged along revolving dial 1 radial symmetric, the revolving dial 1 of this enforcement is connected on lathe, have can supply the top tapering through hole passed of headstock in revolving dial 1 central axial direction, a card of revolving dial 1 has flange, to lead to headstock is top.
Adjustable block-dialing structure comprises shifting block body 2, adjustable grip block 3 and screw 5, the outer end of shifting block body 2 is fixed on by trip bolt 54 in the card of revolving dial 1, the inner of shifting block body 2 has boss, the outer face of boss is provided with guide groove, the bottom land of guide groove is provided with screwed hole, and adjustable grip block 3 is arranged in guide groove.
As depicted in figs. 1 and 2, the radial direction along adjustable grip block 3 has the adjustment hole 31 of strip, and the screw rod of screw 5 and can be tightened in the screwed hole of the low setting of guide groove groove through adjustment hole 31, and the head of screw 5 can compress the outer face of adjustable grip block 3.
In the present embodiment, the inner of adjustable grip block 3 has the identical taper face of 6 taperings top with headstock, so that the insertion that headstock is top.
The outer bowlder of crusher drill, the taper shank 7 of drill bit is inserted between two groups of adjustable grip blocks, and hold by the headstock of lathe is top, regulate the taper shank of the distance clamping drill bit between two groups of adjustable grip blocks, then the screw rod of screw is made to be threaded with shifting block body through adjustment hole, the head of screw compresses the outer face of adjustable grip block simultaneously, with fixing adjustable grip block.
Above-described is only the preferred embodiment of the present invention, it should be pointed out that to those skilled in the art, and under the prerequisite not departing from structure of the present invention, can also make some distortion and improvement, these also should be considered as within protection scope of the present invention.
