Abstract
The present invention relates to a kind of Novel welding types to connect spiral pin, belongs to coal mine machinery technical field.Including square toes and spiral pin, the square toes weld together with spiral pin.Aperture is equipped among the square toes, the spiral pin head is equipped with inserting section, and square toes are mating by aperture and inserting section with spiral pin, and aperture and inserting section are welded.The beneficial effects of the present invention are: spiral pin is divided into spiral pin and square toes two parts by structure optimization, square toes and spiral pin are by mating, then plug welding is full, completes connection spiral pin manufacture and reduces forging and stamping, vertical milling link after this structure.Both it can guarantee its pin shaft intensity, and met requirement, and improve production efficiency, reduce manufacturing cost.
Description
Technical field
The present invention relates to a kind of Novel welding types to connect spiral pin, belongs to coal mine machinery technical field.
Background technique
The spiral pin used on coal mine hydraulic supporting and scrapper conveyor attachment device connector, use scope is wide, and dosage is big, easily
Damage.Currently, coal mine hydraulic supporting is connected by connector with transporting equipment scrapper conveyor, connector one end passes through perpendicular pin and liquid
Bracket pusher rod is pressed to be connected, other end is connected by horizontal spiral pin with scrapper conveyor otic placode, since down-hole coal excavation working face is uneven,
For hydraulic support during pushing and sliding and shifting frame, which is particularly easy to deformation and fracture simultaneously by moment of flexure and torque, at
For rapid wear stressed member on hydraulic support, frequently, usage amount is big for replacement.The head of existing spiral pin be it is rectangular, by full-size
It, need to be by freely forging and pressing after blanking, trolley, vertical milling, quenched ability machine-shaping；If routinely processing technology produces this spiral shell
Pin, complex procedures waste material, and the production cycle is long.
Summary of the invention
Place in order to overcome the above-mentioned deficiencies of the prior art, the present invention provide a kind of Novel welding type connection spiral pin, now lead to
Structure optimization is crossed, common spiral pin is optimized for a kind of Novel welding type spiral pin, that is, is able to satisfy production and requirement.
The present invention is achieved through the following technical solutions: a kind of Novel welding type connection spiral pin, it is characterised in that: including
Square toes and spiral pin, the square toes weld together with spiral pin.
Preferably, aperture is equipped among the square toes, the spiral pin head is equipped with inserting section, and square toes pass through with spiral pin
Aperture is mating with inserting section, and aperture and inserting section are welded.
Preferably, the inserting section and spiral pin are integrally formed, and it be rectangular top is trapezoidal that inserting section, which is section-bottom,
Rotary table, the perimeter of inserting section are less than the diameter of aperture.
The beneficial effects of the present invention are: spiral pin is divided into spiral pin and square toes two parts, square toes and spiral pin by structure optimization
By mating, then plug welding is full, completes connection spiral pin manufacture and reduces forging and stamping, vertical milling link after this structure.It can protect
Its pin shaft intensity is demonstrate,proved, meets requirement, and improve production efficiency, reduces manufacturing cost.
Detailed description of the invention
Below according to drawings and examples, the present invention is further described.
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is the structural schematic diagram of square toes of the present invention；
Fig. 3 is the structural schematic diagram of spiral pin of the present invention.
In figure: 1, square toes, 2, spiral pin, 3, inserting section, 4, aperture.
Specific embodiment
Such as a kind of Fig. 1 to Novel welding type connection spiral pin shown in Fig. 3, it is characterised in that: including square toes 1 and spiral pin 2, institute
The square toes 1 stated weld together with spiral pin 2.
Preferably, aperture 4 is equipped among the square toes 1,2 head of spiral pin is equipped with inserting section 3, square toes 1 and spiral shell
Pin 2 is mating by aperture 4 and inserting section 3, and aperture 4 and inserting section 3 are welded.
Preferably, the inserting section 3 and spiral pin 2 are integrally formed, and it be rectangular top is trapezoidal that inserting section 3, which is section-bottom,
Rotary table, the perimeter of inserting section 3 is less than the diameter of aperture 4.
Spiral pin is divided into spiral pin 2 and 1 two parts of square toes by structure optimization, square toes 1 and spiral pin 2 by mating, then
Plug welding is full, completes the manufacture of connection spiral pin, after this structure, reduces forging and stamping, vertical milling link.Both it can guarantee its pin shaft intensity,
Meet requirement, and improve production efficiency, reduces manufacturing cost.
