CN2067630U - Fast anvil vice - Google Patents

Abstract

The utility model relates to a fast anvil vice, comprising a combining and dividing nut mechanism which comprises a cone grinder with three working face pieces and a half nut pair except for the general conventional anvil vice parts of a movable vice body, a still vice body, etc. A handle is turned in a positive direction so that the fast anvil vice can jog in big pressure in the full travel of a vice jaw. When the handle is reversed, a screw thread pair can be invalidated so that the vice jaw can be pushed and pulled by hands to rapid vary. The design aims of use performance, manufacturing technique, structure cost, etc. can be fully optimized. With the combining and dividing nut mechanism having small size, every part of the vice body can be interchanged with the existing slow vice classes so as to conveniently manufacture the utility model and replace the older generation of the ordinary vice class by the utility model. The fast anvil vice is best in all same class designs at present.

Description

Fast anvil vice

Belong to hardware ﹠ tools, be used for pincers worker, machine work industry clamping work.

Existing fast tighten vice, flat-nose pliers (hereinafter to be referred as the pincers class).CN86207594 is arranged both at home and abroad, CN87213118, CN86205524, CN87216467, CN87213876, CN88204343, CN88205470.CN88205780, CN88207973, CN88207120, CN88208247, CN88208757, CN88216509, CN88220403, CN88220522, CN88221392, CN88106419, the spy opens clear 62--114883, GB2182271, US4262892.US4232857, DE3228646, DE2909937, FR2380847, FR2358959.SU1158337, SU3949538 etc., their major defect is that technology is immature, and mechanism's volume is big and complicated.For example because screw rod, nut when closing button the top tooth and all can only adopt the screw thread on not wear-resisting canine tooth top, can't adopt and respectively clamp trapezoidal thread and the thread rolling processing that class factory has finalized the design.Most parts such as the ambassador of mechanism caliper can not exchange with the existing class that clamps at a slow speed.Going into operation needs huge fund and longer cycle, causes the product price too high.Old pincers class price is extremely low, many factories are only to reduce by one, two kilogram of cast iron weight profit of just making a profit, and leans on big output and obtains existence.It is big slightly to close the branch parent agency, and overall volume and weight just increase considerably.Output is big, loses just hugely, remedy, and price is just expensive.Therefore almost clamping class factory does not always accept these patents.Though individual other has exploitation, also all too high at present because of cost, problem such as screw thread is not wear-resisting, quality, performance and the predicament that is in jeopardy.Facts have proved that existing all patents can't clamp the class competition at a slow speed with former, is no vitality.

The design will accomplish to pull and just change jaw size fast, can clamp the powerful slow-motion of dehiscing entirely.The branch nut body that closes that adopts is answered dependable performance, realize to adopt trapezoidal one chasing such as grade to pay and top tooth not, and volume and manufacturing cost and the former class guiding nut that clamps at a slow speed are all of slight difference, finally make most parts and the general exchange productions of former pincers class such as caliper.

Accompanying drawing 1 is the general structure installation diagram, and accompanying drawing 2 is for closing the dress figure of branch parent agency portion, and accompanying drawing 3 is the parts explosions that close the branch parent agency, and accompanying drawing 4 is three working face figure of three types, and accompanying drawing 5 is four kinds of job state figure that close the branch parent agency.

The design sees that Fig. 1 is by caliper mechanism with close 2 two parts of branch parent agency and constitute.Caliper mechanism is identical with the former class that clamps at a slow speed, and it comprises moving caliper 1, fixed caliper 3, handle and base etc.Closing the branch parent agency is paid by three working face spares, conical friction device and half-nut spiral and forms.

Three working face spares are seen Fig. 2,3, can adopt the 12a type of two rivetings (spiral shell) nail or the 12b type of fitted key, they are assemblied on the overcoat 13, also make the 12c type of one with overcoat, they all are that end face is narrow, cross sectional shape is rectangle, or trapezoidal less than 45 ° of waist and sagittal plane angle (to call radial angle in the following text).Apical side height is greater than the screw flight height.The conical friction device is made up of tapered sleeve 10, stage clip 11, gland 9, overcoat 13, side nail 6.The tapered sleeve cylindrical is tapered, and endoporus has key and sliding being enclosed within on the screw rod 4 of keyway with joining.The endoporus of overcoat is concentric with cylindrical, the taper hole that the one end is and tapered sleeve outer cone circle cooperates, the other end is a cylindrical hole, in the gland 9 of stage clip 11 and close-fitting is arranged.Stage clip presses tapered sleeve makes tapered sleeve cooperate the conical surface to produce constant frictional force with overcoat, constitutes the frictional force of conical friction device.Reducing two cover cooperation taperings or increase this frictional force of stage clip pressure just can be greater than three working face spare top pivoting friction resistance.Side nail 6 is that rivet or screw also can be pins, and it is assemblied in conical friction device side and presss from both sides 90 ° with three working face spares.The half-nut spiral is paid by watt frame 7, screw rod 4, top board 5 and is formed.There is a slotted hole that is enclosed within on the screw rod watt frame two sides, the lower end in one hole is the semicircle screw that matches with screw flight, the semicircle screw also can be in the upper end but not as design good in the lower end, the other end of semicircle screw is the semicircle unthreaded hole of slightly larger in diameter in the screw flight external diameter, semicircle screw screw thread is that the trapezoidal thread manufacturability is best, also can be rectangle, sawtooth, screw thread such as common.Two semicircle orifice centre-to-centre spacing are greater than the screw flight height.A groove is arranged at watt frame front center top, groove upper cap top board 14, forms a square hole, is putting three working face spares and conical friction device in the hole, square hole one side is made up of two vertical planes, and the horizontal transition face that this two vertical plane is close in two semicircle orifice centers two is called confined planes 5.The square hole height equals conical friction device cylindrical and the high sum of three working face spares, is exactly a watt frame bottom land at the bottom of the square hole, it with watt frame slotted hole at the bottom of high poor in conical friction device cylindrical and screw rod tip circle two radius.If half screw is in the slotted hole lower end then there is a chamfering to be called retaining mouthfuls 15 on the same direction of top board bottom surface and three working face spare movement locus, if half screw is in the slotted hole upper end, then the position of retaining mouth is not on top board, but same to watt frame groove bottom on, retaining mouthful should be during at screw rod and semicircle screw top tooth from slotted hole center vertical plane distance, and leading flank can tangle the retaining mouth and is as the criterion in rotating with three working face spares.Retaining mouthful and the inclination angle of horizontal plane can be big or small and select for use in 0～45 ° neatly according to the frictional force of conical friction device.And select angular dimension for use and do not require too strictly, the general equal top tooth of eliminating is selected well with bad, is handle feel quality and job stability is variant.

During operation, the counter-rotating handle, screw rod drives the conical friction device and rotates.Because of its frictional force greater than the frictional resistance of three working face spare end faces, overcoat just rotates, and follows closely limited face up to side and stops that the conical friction device skids and just stops.Because of three working face spares and 90 ° on side nail folder.Three working face spares just go to watt frame groove bottom and stop 12 α attitudes as (I) among Fig. 5.Be higher than screw flight because of three working face spares, screw flight just is ejected a attitude of (I) among Fig. 5 that half screw forms two thread separation, and screw rod enters the top board sulculus and surpassed semicircle, just can freely move axially.Jaw just can pull, and changes size fast.Just change (be among Fig. 5 K to) handle, three working face spares just rotate, and narrow because of end face, it just skids off a watt frame bottom land rapidly, become the 12 β attitudes of (II) among Fig. 5.Again because of the side radial angle less than 45 °, just fall on half-nut by weight as the screw rod freely falling body, two screw threads are leaning as the b of (II), (III) among Fig. 5 and c dynamic relocation rotation can be bordering on 180 °.(because three working face spares can go to retaining mouthful place).The axially-movable of screw flight also is nearly 1/2nd pitch in the rotation, will overcome the top tooth of the overwhelming majority.Again because the retaining open height just is slightly larger than screw rod and half-nut two is threaded into button back three working face spare end face rotary motion trace circle.So the side of three working face spares will inevitably be tangled 12r attitude as (III) among Fig. 5 by retaining mouth during the tooth of top.Because of the side radial angle less than 45 °, will produce very big circumferential resistance, the conical friction device is constantly skidded, screw rod just constantly rotates with excellent handle.Can be threaded into a shape that is buckled among watt frame half screw such as Fig. 5 to (as trapezoidal, the rectangle) of any wide crest.At this moment three working face spares also just fall along with screw rod and break away from retaining mouthful and rotate, and stop and stop the 12w attitude that is stuck in (IV) among top board top such as Fig. 5 up to the another side of limited of side nail.Screw rod, half-nut are locked into fixing spiral and are paid.At this moment jaw just has the pressure slow-motion function of dehiscing entirely, can carry out former all operations that clamp class at a slow speed.

Three working face spares top is three working faces that the position is different with function with both sides, because their appearance, just breaking through at present fast the pincers class adopts chasings such as trapezoidal, rectangle to pay when closing button not top tooth, and the difficult point that feel is fabulous, this is that structures such as employed off-centre operation, cam do not have to propose and solve in the existing patent family.Existing patent screw rod descends the slow evening that contacts with nut, top power is very big during contact, no peripheral force skids by fastness, does not also find and attempts to adopt special cam and the method that produces peripheral force allows screw rod skid to overcome the top tooth, only remove to eliminate the top tooth with the canine tooth screw thread.Cause screw thread because of not wear-resisting, manufacturability is poor, embarrass technology, frock to optimize the old pincers of typing class factory and accept enforcement.Conical friction device among the design also is much better than similar: not only it is wear-resisting, stable performance, material and processing are also economical especially, and volume is little, and diameter can be as small as only bigger three millimeters than screw rod, and length can be as short as 1～1.5 centimeter, can allow watt frame two ends half screw extend, gain in strength and wearability.Top board can be one time punching molded, and shared volume is minimum, and is very economical.But all this reasons originally close the branch parent agency with the guiding nut size basically identical that clamps class at a slow speed, finally make most parts such as caliper can with clamp class at a slow speed and exchange.Allow knowhow, all old factories of Sales Channel only change few investment and just can change the line of production on a large scale, formed overall advantage such as quality, output, price, Sales Channel in a short time.Extensive rapidly renewal old product is become a reality.As run into sales difficulty, still can be adapted as the former series products that clamps at a slow speed and eradicate the risk of changing the line of production on a large scale.

The batch sample of having informed against at present, very being subjected to clamp always class factories likes the enforcement of all will trying to be the first.Through the strict test of authoritative unit, every index is all-round excellent, particularly strength test, and folder power reaches 5600 Newtonian times, and is damaged with the caliper that old product is general, and it is excellent originally to close sub-agencies, proves that design is very superior.
