The specific embodiment
Accompanying drawing is depicted as the embodiment of the two pawl jigs of a kind of tooth wedge of the utility model, as Fig. 1, Fig. 3, Fig. 8, Fig. 9, shown in Figure 10, it is made up of band blade tooth bar 1, band pawl sliding sleeve 2 and tooth wedge 3, band blade tooth bar 1 is made of ratch and claw, ratch one termination is a claw, be provided with a slotted hole 11 in the middle of the ratch, these slotted hole 11 1 sides are provided with row's helical teeth hole 12; Band pawl sliding sleeve 2 is made of sliding sleeve and claw, and sliding sleeve one termination is provided with and the identical claw of ratch claw structure external form, and ratch inserts in the vertical oblong aperture 22 of sliding sleeve, and two claws are symmetrical arranged in opposite directions during plug-in mounting; Be provided with oblong aperture 21 in the middle of the horizontal side of sliding sleeve, with corresponding overlapping behind slotted hole 11 plug-in mountings in the middle of the ratch; Tooth wedge 3 is provided with one group of vertical helical teeth 31 on the rectangular plate body of one side, in tooth wedge 3 vertical insertion sliding sleeves and the overlapping hole of ratch, and the vertical helical teeth 31 on the rectangular plate body of tooth wedge 3 these sides and helical teeth hole 12 corresponding the plugging together of ratch.
Band blade tooth bar 1, band pawl sliding sleeve 2 are fine steel casting with tooth wedge 3 in the present embodiment.Ratch appearance and size is (46 * 18) mm; The vertical oblong aperture 22 of sliding sleeve is of a size of (47 * 19) mm, owing to be precision castings all, ratch can insert the vertical oblong aperture 22 of sliding sleeve smoothly.Moreover band helical teeth slotted hole 11 application length are 65mm in the middle of the ratch, and tooth wedge 3 width dimensions are 25mm, and the difference of the two is 40mm, i.e. coarse adjustment size maximum can reach 40mm, can satisfy this jig fully coarse adjustment claw required distance is installed.The horizontal side of sliding sleeve oblong aperture 21 is of a size of (27 * 18) mm, and tooth wedge cross dimension is (25 * 16) mm, can satisfy the tooth wedge and insert in sliding sleeve and the overlapping hole of ratch.
The claw medial surface 14 of described band blade tooth bar and the medial surface of the ratch 13 vertical perpendicular types substantially of being arranged to are with the claw medial surface 24 of belt transect pawl sliding sleeve and the also vertical perpendicular type substantially of being arranged to of medial surface 23 of sliding sleeve.
The claw of described band blade tooth bar 1 and band pawl sliding sleeve 2 is equipped with assembly unit touches the supporting internal orifice of edges of boards frame external form, and port recess 15,25 are isosceles triangle in two, and angle is between 85～95 °, and touches plate two with assembly unit and link to each other
Type frame profile is coincide, and is convenient to two-way chucking.The interior port recess 15,25 of two claws is isosceles right triangle in the present embodiment, and angle is 90 °.
The claw of described band pawl sliding sleeve 2, the claw and the ratch cross section of band blade tooth bar 1 are " worker " font, and at claw I-shaped web center open- work 16,26 are set all, promptly guarantee longitudinal rigidity, again weight reduction.In the present embodiment as shown in Figure 7, the recessed 1mm of ratch B-B section middle pectoral plate, as Fig. 4, shown in Figure 9, two claw face section web all recessed (6～12.5) mm, open- work 16,26 diameters that claw I-shaped web center is provided with are 20mm.
The claw of described band blade tooth bar 1 and ratch consubstantiality, the claw and the sliding sleeve consubstantiality of band pawl sliding sleeve 2 are one machine-shaping.
The helical teeth hole 12 of described ratch is corresponding mutually with vertical helical teeth of tooth wedge 31, their orthogonal rake is 7～8.5 °, and from 8.53 ° of requirements of the locking angle, the self-locking of tooth wedge helical teeth can not become flexible less than the steel surface pressure, nature claw clamping force can not reduce yet, and realizes the purpose of permanent card pilled-in selvedge frame.Their orthogonal rake is 8 ° in the present embodiment.
Described tooth wedge 3 one ends are provided with hammering 32, are to use during with hand hammer hammering tooth wedge upper end.
Use principle is as follows: shown in Figure 14～16, when the novel all steel form joint of assembly unit, this jig is installed near channel-section steel cross rib and frame infall, the coarse adjustment slide blocks in two two claws to bend
The type frame outside, it is penetrating to adjust overlapping hole, insert the tooth wedge from top to bottom, the tooth wedge can insert sliding sleeve and the overlapping hole of ratch smoothly, corresponding the plugging together in helical teeth hole of vertical helical teeth of tooth wedge and ratch, the suitable hammering tooth wedge down of exerting oneself, till motionless, like this, the tooth wedge promotes slide along the little slip of ratch, make two claws further close, clamp two
Frame.And because helical teeth and helical teeth hole have the engagement self-locking action, slide can not become flexible, and the clamping action of two claws can not become flexible naturally yet, realizes permanent chucking purpose.
Curved in the claw internal orifice and two
The type frame is connected into relatively
Type, back of the body outer shape is identical, has two-way function during the claw chucking, the one, the vertical frame contact surface of claw internal orifice, having equivalence oppositely is close to thrust two frames is close to, the 2nd, claw internal orifice two vertical planes all with contact surface angle at 45, only allow claw contact with 45 ° of faces of frame near panel, and leave minim gap from panel 45 ° of faces far away, then when claw block two connect frames near the time, component with vertical formwork back side makes two frames near the ratch medial surface, makes the form surfacing seam concordant, plays two-way snap action.
