Description
Technical field
This utility model relates to a kind of tooth set toothholder, particularly relates to a kind of adjustable-angle pick-shaped cutter tooth and overlaps toothholder, belongs to industrial attachment technical field.
Background technology
Pick-shaped cutter is widely used in as cut cutter in the mining machine equipment such as various coal-winning machine and development machine, and the installation of various machinery chirotype picks all adopts fixed angle to install, and stress serious wear in the course of the work becomes main attrition component.Owing to, in coal and rock and other mineral forming process, primary deposit thing, carbonization degree of metamorphism are all not quite similar, forming the coal rock layer with different joint, layer reason trend, there is very big-difference in the physical and mechanical property of all directions.The conventional tooth set of pick-shaped cutter, toothholder are cylindrical mounting surface, toothholder is welded on coal mining machine roller or cutting head of roadheader according to the angle designed in advance, manufacturing process is complicated, and can not according to moving towards in coal, rock mass layer to regulate the tangentially mounted angle of pick-shaped cutter and axially inclined angle, in pick work process, abrasion is very fast, and then may result in the abrasion of toothholder even cylinder and cutterhead, badly influence mining efficiency.
Utility model content
In order to solve the weak point existing for above-mentioned technology, this utility model provides a kind of adjustable-angle pick-shaped cutter tooth and overlaps toothholder.
In order to solve above technical problem, the technical solution adopted in the utility model is: a kind of adjustable-angle pick-shaped cutter tooth overlaps toothholder, and it includes toothholder, sphere tooth set, pick-shaped cutter, alignment pin；The tooth handle of pick-shaped cutter is arranged in sphere tooth set；Sphere tooth set is installed in toothholder；Toothholder is split type, is made up of toothholder body and toothholder lid；Toothholder body and toothholder lid are bolted connection；
Set a tangentially oriented counterbore of row on the lateral surface of sphere tooth set vertically respectively, a row axially positions counterbore；Angle between face and the face of the axially central shaft formation of location counterbore that the central shaft of tangentially oriented counterbore is formed is 90 °；The toothholder lid that tangentially oriented counterbore is corresponding has set a tangentially oriented through hole；The toothholder lid that axially location counterbore is corresponding has set an axial positioning through hole of row.
The left end of tooth handle is fixed in sphere tooth set by jump ring part.Alignment pin has two, and one of them runs through tangentially oriented through hole and runs through axial positioning through hole to axially positioning counterbore to tangentially oriented counterbore, another one.Bolt has multiple, and multiple bolts are evenly arranged in toothholder body and the junction of toothholder lid: the tail end of bolt is provided with nut.
This utility model can regulate cutting angle and inclination angle of pick-shaped cutter installation, improves the mounting process of pick-shaped cutter, suitably adjusts cutting-gear-angle according to cut object and will alleviate the abrasion of pick, improves mining efficiency.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
As Figure 1-4, this utility model includes toothholder, sphere tooth set 2, pick-shaped cutter, alignment pin；The tooth handle 4 of pick-shaped cutter is arranged in sphere tooth set 2；Sphere tooth set 2 is installed in toothholder；Toothholder and sphere tooth set 2 are sphere-contact, and the contact area of sphere-contact is big, has stronger impact resistance, it is possible to make job stability strengthen；Toothholder is split type, is made up of toothholder body 1 and toothholder lid 3；Toothholder body 1 and toothholder lid 3 are fastenedly connected by bolt 6；Toothholder body 1 and toothholder lid 3 are fastenedly connected by bolt 6；Renewal part when split-type design is easy to keep in repair, more convenient to operate；
The lateral surface of sphere tooth set 2 has set tangentially oriented counterbore 8, row axially location counterbore 9 of row vertically respectively；Angle between face and the face of the axially central shaft formation of location counterbore 9 that the central shaft of tangentially oriented counterbore 8 is formed is 90 °；The toothholder lid of tangentially oriented counterbore 8 correspondence has set a tangentially oriented through hole；Axially position and the toothholder lid of counterbore 9 correspondence has set an axial positioning through hole 10 of row.
The left end of tooth handle 4 is fixed in sphere tooth set 2 by jump ring part 5.Alignment pin has two, and one of them runs through tangentially oriented through hole and runs through axial positioning through hole to axially positioning counterbore to tangentially oriented counterbore, another one.Bolt 6 has multiple, and multiple bolts are evenly arranged in toothholder body 1 and the junction of toothholder lid 3；The tail end of bolt 6 is provided with nut 7.
Before the use, first rotation spherical tooth set 2 and pick-shaped cutter, be aligned and inserted into alignment pin by tangentially oriented through hole and one of them tangentially oriented counterbore and fix this utility model；Then 2 and pick-shaped cutter is overlapped with above-mentioned alignment pin for axle rotation spherical tooth, they are regulated to position required when using, it is inserted into another alignment pin fixes at the axial positioning through hole alignd and axial location counterbore, so then can realize the fixing of chirotype pick and the adjustment with inclination angles that cuts angle.
The way of contact of this utility model toothholder and tooth set is sphere-contact, has higher impact resistance relative to traditional cylindrical contact surface, can effectively reduce the abrasion of pick-shaped cutter, alleviate production cost and improve work efficiency；Cutting angle and inclination angle of pick-shaped cutter installation can be regulated by positioning the cooperation of counterbore and positioning through hole；Additionally, this utility model manufacturing process is simple, dismounting, easy to maintenance, there is wide applicability.
Above-mentioned embodiment is not to restriction of the present utility model; this utility model is also not limited to the example above; the change made within the scope of the technical solution of the utility model of those skilled in the art, remodeling, interpolation or replacement, also belong to protection domain of the present utility model.
