Description
Technical field
The utility model relates to a kind of timber auxiliary processing device, particularly relates to a kind of timber gland.
Background technology
The advantage such as that wooden boards has is lightweight, strength ratio is high, good springiness, shock-resistant, unity and coherence in writing tone enrich attractive in appearance, handling ease, have resource regeneration simultaneously, and wooden boards all occupies an important position to the present from ancient times in national economy.The wooden boards processing industry, take wooden boards as raw material, is mainly processed with mechanical means.Add first timber to be fixed man-hour and carry out follow-uply as cut the processing such as saw, boring again, fixture is requisite auxiliary equipment in timber.Existing timber fixture has: fixed block, set bolt, platform composite tooling and the Telescopic Fixed head unit of hydraulic jack, the Telescopic Fixed head unit of hydraulic jack has advantages of and uses and simple operation with it, developing into the main flow fixture.Yet existing gland is a rigid member, add that hydraulic jack hydraulic oil is incompressible medium, in practical operation, often because too much to the oil cylinder oiling, cause gland excessive to the bed knife of timber, cause timber by the pressure point excessive deformation even timber damaged by pressure.
The utility model content
For solving above-mentioned hydraulic jack, easily cause gland excessive to the bed knife of timber, cause timber by the pressure point excessive deformation timber problem of being damaged by pressure even, the utility model provides a kind of timber gland.
For addressing the above problem, the utility model achieves the above object by the following technical programs: a kind of timber gland, comprise Connection Block, spring, spring base, telescopic shaft, wing plate, pin and gland, described Connection Block is fixedly connected on the upper surface of spring base; Described spring is arranged in the centre bore of spring base; Described telescopic shaft upper end is arranged in the centre bore of spring base, and links together with the spring lower end; Described wing plate is fixed on the upper surface of gland; Lower end and the wing plate of described telescopic shaft are articulated and connected.
By being connected to the Connection Block on hydraulic cylinder piston rod, when piston rod stretches out, gland and piston rod move simultaneously, when gland contact timber, spring-compressed deformation increases gradually, the spring force that increases gradually simultaneously is delivered on telescopic shaft and gland, finally acts on timber, realizes the fixing of timber.and in realizing fixing process, spring deformation is according to the gradual change of the extension elongation of piston rod and gradual change, it is bed knife gradual change along with the spring deformation of gradual change, when timber is wedge shape timber, the form that is articulated and connected by being arranged to telescopic shaft and wing plate, gland and wing plate can circumferentially rotate along pin, compounding practice workman rotary fixed head again, can meet gland contact parallel with lozenges, the hinged assembling that is easily to realize described fixture of dismountable pin, namely worked as the telescopic shaft lower end before being connected and fixed head, in the spring base outside, complete being connected of spring base and telescopic shaft, again the telescopic shaft lower end is penetrated to the spring base centre bore from the spring base upper end, complete telescopic shaft, spring is with respect to the assembling of the position of spring base, complete again the installation of holder and gland.
As preferably, described Connection Block is that slip-on-welding plate flange ，Qi center boring ratio spring outer diameter is large, and and the upper surface of described spring base between adopt and be welded to connect.
The Connection Block that is slip-on-welding plate flange is easily made, simultaneously with piston rod, becoming bolt to be connected to removably connects, add the upper connecting base centre bore and be arranged to more biggerly than spring outer diameter, be convenient to the replacing of the spring of different coefficient of elasticity, make described timber gland applicable situation more extensive; Because Connection Block and spring base all are not subjected to service load at work, two members in use are not easy to occur damaging, and are set as between the upper surface of Connection Block and spring base and adopt non-dismountable connection, convenient welding and the firm and reliable connection that is welded to connect.
As preferably, described spring is conical Compress Spring, and its cone end is arranged on the bottom of spring base.The Diameter Gradual Change section that the bottom of described spring base has one section diameter to diminish gradually, the cone end of described spring is arranged in the Diameter Gradual Change section of spring base.
The upper end of described telescopic shaft is provided with external screw thread, and thread segment is arranged in the endoporus of cone end of spring, uses the nut supporting with described telescopic shaft external thread section screw thread to be fixedly connected with spring.This arranges can realize easily that the axiality that spring lower end and telescopic shaft be connected in the axial direction is good, avoids occurring at work that spring distorts, and causes spring shape sudden change in compression process, the spring force of output mutation; But the Diameter Gradual Change section restraining spring of spring base, telescopic shaft, gland mechanism do not break away from spring base.
Further, the center that be projected in gland of described telescopic shaft on gland, described two blocks of wing plates are with respect to the telescopic shaft symmetry.The center that be projected in gland of telescopic shaft on gland, two blocks of wing plates are convenient to stressed uniform distribution on gland with respect to the telescopic shaft symmetry.
Utility model compared with prior art, has following beneficial effect:
A kind of timber gland that the utility model provides, by being connected to the Connection Block on hydraulic cylinder piston rod, when piston rod stretches out, gland and piston rod move simultaneously, when gland contact timber, spring-compressed deformation increases gradually, and the spring force that increases gradually simultaneously is delivered on telescopic shaft and gland, finally act on timber, realize the fixing of timber.And in realizing fixing process, spring deformation is according to the gradual change of the extension elongation of piston rod and gradual change, i.e. bed knife gradual change along with the spring deformation of gradual change.Can prevent effectively that the bed knife sudden change from causing timber excessive deformation or damage, and according to different occasions also replaceable appropriate spring and the telescopic shaft of different length, telescopic shaft and wing plate adopt and are articulated and connected, and make the novel a kind of timber fixture that provides of this use be applicable to the fixing of lozenges timber.
