Description

Positioner on a kind of diamond segment welding stand cutter head folder

Technical field

The utility model belongs to field of mechanical technique, relates to a kind of positioner, the positioner on particularly a kind of diamond segment welding stand cutter head folder.

Background technology

Positioner on the existing diamond segment welding stand cutter head folder generally comprises over against the front clamp seat of setting and its lobed locating piece in lower end and back grip slipper, be provided with the location structure that is connected on the cutter head elevating mechanism and has reference column between the grip slipper of front and back, it is when the welding cutter head, its reference column is pressed on the cutter head upper surface, the cutter head lower surface is resisted against on the saw blade, because reference column is that single-point positions saw blade, its cutter head can rotate around the compress some front and back of reference column on cutter head when welding, in order to overcome this problem, generally be the locating piece on the grip slipper of front and back to be clamped in simultaneously on the two sides of cutter head cutter head to be maintained static moving, but exist some problems, mainly be: the one, can lose by two locating pieces a cutter head heating heat part, it is low to cause heating welding efficiency; The 2nd, cutter head is heated inhomogeneous, has reduced the welding quality of cutter head; Three is that two locating pieces directly are subjected to the high temperature heating, thereby the life-span reduces.

Summary of the invention

The purpose of this utility model is to have the problems referred to above at existing technology, has proposed a kind of can the raising the positioner on the diamond segment welding stand cutter head folder of the welding efficiency of cutter head and welding quality.

The purpose of this utility model can realize by following technical proposal: the positioner on a kind of diamond segment welding stand cutter head folder, be arranged on the elevating mechanism of diamond bonding machine cutter head folder, be used for location to cutter head, comprise front clamp seat and back grip slipper over against setting and its lobed locating piece in lower end, the upper end of described front clamp seat and back grip slipper is connected on the above-mentioned elevating mechanism and its two locating piece can be clamped the cutter head two sides, be provided with the extruding seat that is connected on the above-mentioned elevating mechanism between described front clamp seat and the back grip slipper, it is characterized in that: the bottom of described extruding seat is provided with the location structure that has two wedge angles, and described two wedge angles can position the cutter head upper surface.

Be equipped with cylinder on the grip slipper of front and back, when work, cutter head is placed between the grip slipper of front and back, starting cylinder work makes two locating pieces on it clamp cutter head, it is descending that elevating mechanism drives this positioner, two wedge angles on the location structure withstand the upper surface of cutter head and the lower surface of cutter head tightly are resisted against on the saw blade, start cylinder work once more and make two locating pieces unclamp cutter head, then cutter head are added thermal weld.Owing to be that two wedge angles carry out two point locations to the cutter head upper surface, so unclamp at two locating pieces the situation of rotating before and after the cutter head can not appear yet when not clamping cutter head.This structure can make and cutter head be added thermal weld in the heat hot quantity set, heat is difficult for scattering and disappearing and can also reaching the cutter head thermally equivalent, not only welding quality is good but also make the cutter head welding efficiency can improve 10%～20%, simultaneously, because two locating pieces no longer directly are subjected to the high temperature heating, have prolonged its service life greatly.

In the positioner on above-mentioned a kind of diamond segment welding stand cutter head folder, described location structure comprises connector and has above-mentioned two wedge angles and be the keeper of " U " type, the upper end of described connector has external thread structure, its bottom is to have a groove on hexagonal cylinder and its for its cross section, above-mentioned keeper is fixed in the groove, and described connector is threaded with the extruding seat.

Location structure and extruding seat detachably, when location structure has damage, can be changed location structure separately, thereby can save cost for being threaded; Screw connection structure can also be regulated the high and low position of two wedge angles simultaneously.If cutter head is long, the length that keeper can be processed a bit makes the distance between two wedge angles big a bit to adapt to the length of cutter head.

In the positioner on above-mentioned a kind of diamond segment welding stand cutter head folder, the upper end of the described connector hold-down nut that has been threaded.

Can make connector can more firmly be fixed on the extruding seat by regulating hold-down nut, guarantee that two wedge angles are more firm to the location of cutter head.

In the positioner on above-mentioned a kind of diamond segment welding stand cutter head folder, described keeper is made by Hardmetal materials.As preferably, described keeper is made by wolfram steel.

The keeper intensity height that carbide alloy is made, high temperature resistant and wear-resistant is suitable for the high temperature heating environment.

In the positioner on above-mentioned a kind of diamond segment welding stand cutter head folder, described locating piece is made by pottery or Hardmetal materials.

Compared with prior art, the positioner on the diamond segment welding stand cutter head folder has following several advantage:

1, owing to the cutter head upper surface is carried out two point locations by two wedge angles, make cutter head in welding process, do not need before and after two locating pieces on the grip slipper cutter head is fixedly clamped also can guarantees the cutter head phenomenon that can not rotate;

2, add in the thermal weld at cutter head, two locating pieces do not contact with cutter head, make in the heat hot quantity set cutter head heating has been improved the welding efficiency of cutter head, and simultaneously, cutter head is heated evenly, and has improved the welding quality of cutter head;

3, add in the thermal weld at cutter head, its two locating piece no longer directly is subjected to the high temperature heating, thereby has prolonged its service life, the clamping precision of two grip slippers before and after also having improved simultaneously.
