CN2057131U - Fast anvil vice or plain vice - Google Patents

Abstract

The utility model relates to a fast anvil vice or a plain vice, comprising a fire-new combining and dividing nut mechanism which is formed in a step mode by going through a plurality of generations patent practices, a positive turning handle. A screw thread pair is validated so that the screw thread pair can jog with big pressure in the full travel of a vice jaw. The utility model has the all functions of the existing slow vice class. When the utility model is reversed, the 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 class 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 or the plain vice is best in all same class designs at present.

Description

Fast anvil vice or plain 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, C88205780, 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.Factory of the maximum a few family of output in domestic and quality influence, as reaching 1,000,000 half Laizhou and bench vice factories such as Taizhou that account for national output year, conscientiously investigated 5 years, domestic relevant inventors nearly all looked for to the doorstep, the repeatedly enthusiasm that has is recommended, but these factories think that all patents can't adopt.Though exploitation is arranged, is full of the pincers class is produced and sold the new factory that rawness lacks investigation again.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, realizes adopting 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.

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 see that Fig. 2,3 can adopt 12a type or 12b type that fitted key is formed of being made up of two rivetings (spiral shell) nail, they are assemblied on the overcoat 10, also with overcoat all-in-one-piece 12c type, they all are that end face is narrow, cross sectional shape is rectangle, or waist and sagittal plane angle t(are to call radial angle in the following text) can be 0 °～45 ° trapezoidal.Apical side height is greater than the screw flight height.The conical friction device is made up of tapered sleeve 11, stage clip 9, gland 7, overcoat 10, 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 7 of stage clip 9 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 13, screw rod 4, top board 5 and is formed.There is groove at watt top of the trellis center, half screw that two ends respectively have a mouth to make progress.Half screw adopts trapezoidal thread manufacturability the best, also can adopt rectangular thread, saw-tooth thread, regular screw threads.Top board becomes ㄇ shape frid to constitute by three side-lookings, and the centre is a vat, and two is a sulculus, and is joined together by the transition panel.The vat bottom is enclosed within watt frame both sides, center and fixing, in, top and a watt frame groove surround a square hole, placing three working face spares and conical friction device in the hole, is exactly a watt frame bottom land at the bottom of the hole, and it equals overcoat and the high sum of three working face spares apart from the height of half screw root of the tooth.The sulculus at top board two is buckled in also concentricity of watt top of frame two halves screw.Two little groove widths are slightly larger than the screw rod external diameter, deeply greater than screw rod tip circle radius and three working face spare sums.Be wider than the side surface of top board the same side with three working face spare rotary motion trace semicircle tops, a retaining mouthful square hole 14 is arranged on this side.Its wide and height can make three working face spares change and run off the top board surface.The square hole top is retaining mouth 8, and the retaining open height is slightly larger than screw rod and half screw is threaded into when detaining, the track tip circle that three working face spares rotate.The top board opposite side relative with retaining mouthful square hole can have square hole, also can not have square hole.There is square hole can allow overcoat run off top board, shortens and close branch parent agency width.Also can not design and keep off a mouth and a retaining mouthful square hole, replace keeping off the effect of mouth with the big bottom land of top board.During the top tooth,, can reduce the frictional force that stage clip pressure reduces the conical friction device, can allow equally and skid and eliminate the top tooth though that big bottom land blocks the peripheral force that three working face spare sides are produced is less.Do like this with reducing the reliability of anti-top tooth and increasing mechanism's width, though, permit in the ordinary course of things not as the former.

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 is stopped that by half screw limit portion the conical friction device skids and just stops up to the side nail.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 12d attitude as Fig. 5-I.Because of three working face spares are higher than screw flight, screw flight just is ejected a attitude that half screw forms Fig. 5-I of 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 12 β attitudes of Fig. 5-II.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 Fig. 5-II, 5-III and c dynamic relocation rotation can be bordering on 120 °.(because three working face spares can go to retaining mouthful place).The axially-movable of screw flight also is nearly 1/3rd 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 Fig. 5-III 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 the d 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 are stopped by the another side of half screw and stop the 12w attitude that is stuck in top board top such as Fig. 5-IV up to the 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 56000 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.
