Abstract
The invention discloses a clamping device for repair of a blade top. The clamping device comprises a fixture block, a pre-tightening piece, tightening screws and a base for supporting the fixture block, wherein the fixture block comprises two opposite clamping plates; supporting plates for clamping and positioning a blade tenon head are arranged on two opposite end surfaces of the two clamping plates; the distance between the supporting plates is adjusted by the aid of the pre-tightening piece, and then the clamping force applied to a blade tenon root by the supporting plates is adjusted; and the tightening screws are arranged on the two clamping plates and are used for clamping and fixing the upper section of a blade. Even if the torsional deformation and sizes of blades are different, all that is required for clamping and fixing upper sections of the blades is to abutting the tightening screws on the two clamping plates against the upper sections of the blades from two sides of the blades respectively.

[detailed description of the invention]
Illustrated in greater detail embodiments of the present invention below in conjunction with the accompanying drawings, embodiments of the invention
It is in order to the present invention is further explained, rather than protection scope of the present invention is limited.
Referring to shown in Fig. 1 and Fig. 2, the clamping device of the present invention includes clamp block 10, pretension
Part 11, trip bolt 12 and for supporting the base 13 of described clamp block 10, described clamp block
10 include two pieces of clamping plate being oppositely arranged 101, two end faces that two pieces of described clamping plate 101 are relative
On be provided with the gripper shoe 102 for clamping and position described blade tenon, two pieces of described supports
Distance between plate 102 is regulated by described preload piece 11；Described preload piece 11 includes a spiral shell
Bolt 111 and a nut 112, two pieces of described clamping plate 101 are provided with placement hole, described bolt
After 111 bolts are also cross the placement hole on two pieces of described clamping plate 101, described nut 112 and spiral shell
Bolt 111 threaded engagement is for adjusting the distance between described two gripper shoes 102, thus adjusts two
The described gripper shoe clamping force to described blade tenon；When the tenon of described blade is placed on two pieces of institutes
After stating between gripper shoe 102, tighten described nut 112, make two pieces of described gripper shoes 102 clamp
The tenon of described blade；After reblading has worked, only described nut 112 need to be unscrewed,
The tenon of described blade can be taken out smoothly, improve installation and removal efficiency.Preferably, for
Make the fixing more firm of described blade tenon, gripper shoe 102 on two pieces of described clamping plate 101
It is positioned on same level line.
The fastening in epimere portion for fixing described blade it is provided with on two pieces of described clamping plate 101
Screw 12, and described trip bolt 12 the most totally two groups.By on two pieces of described clamping plate 101
Trip bolt 12 is respectively held against the epimere portion of described blade thus realizes described from described blade both sides
Blade epimere portion is fixed.It is arranged such that and makes the torsional deflection of described blade and size not
With, as long as by the trip bolt 12 on described two pieces of described clamping plate 101 from described blade both sides
Respectively against the epimere portion of described blade thus realize the fixing of described blade epimere portion.In order to reach
To fixed effect more preferable to described blade, described trip bolt 12 both passes through fixes the described of its
Clamping plate 101, and be oppositely arranged.
Of course for reaching more preferable fixed form, it is also possible on two pieces of described clamping plate 101 all
Many group trip bolts 12 are set, select different according to the torsional deflection situation of described blade
Described trip bolt 12 is fixed.
In the present embodiment, the thickness of described two clamping plates 101 upper end is all higher than bottom
Thickness.Owing to screwed hole can be offered for arranging many groups tightly in described two clamping plates 101 upper end
Gu screw 12, bulk strength can weaken, and adds repeatedly tightening of the described trip bolt 12 of many groups
With unscrew to making more than 101 stress of described two clamping plates, it is most likely that occur damage and cause breaking
Split.The thickness of described two clamping plates 101 upper end is all higher than the thickness of bottom, is possible not only to
Improve the intensity of two pieces of described clamping plate 101 upper ends, reduce the probability of fracture, it is also possible to make institute
State trip bolt 12 by fixing for described blade epimere portion more firm.
The present invention by arranging gripper shoe on the face relative at two pieces of described clamping plate, for clamping and
The tenon of locating blades, arranges fastening spiral shell the most more than two on two pieces of described clamping plate simultaneously
Nail for fixing the epimere portion of blade, be arranged such that make described blade torsional deflection and
Size is different, as long as by the trip bolt on two pieces of described clamping plate from described blade both sides respectively
The epimere portion propping up described blade can realize the fixing of described blade epimere portion.
Being provided with an arc guide rail 131 on described base 13, described clamp block 10 includes with described
The supporter 103 that arc guide rail 131 coordinates, described supporter 103 can be along described arc guide rail
131 slide.When described supporter 103 slides along described arc guide rail 131, two pieces of described folders
Plate 101 can occur the inclination of different angles, is also secured between two pieces of described clamping plate 101
Need the described blade repaired that angle also can be occurred to tilt, just can realize the leaf to described blade
Pelvic surface of sacrum or the Repair gene of leaf back, as shown in Figure 3 and Figure 4.It should be noted that herein
Postpone when described supporter 103 slides into specific bit along described arc guide rail 131, need by solid
Locking member its be fixed on described base 13, prevent from repairing during described blade, described
The repair of blade described in support body 104 wobble effects back and forth.Such as can be at described base 13
On two groups of relative screwed holes 132 are set, postpone when described supporter 103 slides into specific bit, logical
Cross bolt part 133 to coordinate with described screwed hole 132, prop up institute from described supporter 103 both sides
State supporter 103, thus realize the fixing of described supporter 103.
In addition to reach more preferable fixed effect, it is also possible to described base 13 by screw or
Person's bolt connection piece fixes a tabletting 14, and described tabletting compresses described supporter 104 He simultaneously
Described base 13.
In the present embodiment, described arc guide rail 131 is matrix arc guide rail, implements at other
Arc guide rail 131 described in mode can also be convex arc guide rail.
Certainly, the above is the preferred embodiment of the present invention, it is noted that for this skill
For the those of ordinary skill in art field, under the premise without departing from the principles of the invention, it is also possible to
Making some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
