Abstract
A processing device of a screw with a square head is composed of a locating base, a locating and fastening nut, a locating screw, a flat clamping board, a V-shaped groove clamping board, a clamping base, a square trimming mould, a fixing nut, a cutting piston bar and a cutting hydraulic cylinder. The locating screw is fixed on the locating base in threaded connection mode and is reinforced through the locating and fastening nut. The square trimming mould is fixed on the cutting piston bar through the fixing nut. The V-shaped groove clamping board and the flat clamping board are installed on the clamping base. The cutting piston bar and the cutting hydraulic cylinder are connected. Due to the fact that the processing device of the screw with the square head is adopted, the screw with the square head can be machined and produced, wherein the screw with the square head is 8-16mm in diameter and 70mm in length of the square head. Machining is easy and convenient, and the processing device of the screw with the square head is suitable for mass production of products.
Description
Technical field
The present invention relates to a kind of machinery processing apparatus, specifically a kind of processing unit (plant) of square head screw rod.
Background technology
The square head screw rod uses extensively as a kind of common fastener products, and daily demand is huge.The processing method of square head screw rod mainly contains two kinds, is respectively punch press extruding and milling machine Milling Process.Utilize punch press to carry out extrusion process screw rod square head, its surface roughness is relatively poor, is difficult to guarantee the screw coaxial degree, and process operation is complicated, and extruding square head length is unsuitable long, and can't process the length of side less than screw diameter square head screw rod.Utilize milling machine to carry out Milling Process screw rod square head, production efficiency is low, is not suitable for producing in enormous quantities.
Summary of the invention
The processing unit (plant) that the purpose of this invention is to provide a kind of square head screw rod adopts this device can produce M8～M16, the longest square head screw rod that reaches 70mm of square head length.
The present invention achieves the above object by the following technical programs: a kind of processing unit (plant) of square head screw rod, consisted of by positioning seat, location clamp nut, positioning screw, flat fishplate, V-shaped groove clamping plate, clamping seats, cubic edger, hold-down nut, cutting piston rod and cutting fluid cylinder pressure, concrete structure and connected mode are: positioning screw is threaded connection and is fixed on the positioning seat, and the location clamp nut is reinforced positioning screw; The four directions edger is fixed on the cutting piston rod by hold-down nut; V-shaped groove clamping plate and flat fishplate are installed on the clamping seats, and the cutting piston rod is connected with the cutting fluid cylinder pressure.
Described V-shaped groove clamping plate and flat fishplate form clamp mechanism and are fixed on the partially rear position of workpiece centre.
The processing method of the processing unit (plant) of described square head screw rod, comprise the steps: to utilize V-shaped groove clamping plate and flat fishplate combination clamping work pieces, by the positioning screw positioning workpieces, by the hydraulic cylinder piston rod reciprocating motion that cubic edger is housed workpiece is cut, make workpiece be the square head screw rod.
Described square head screw rod is M8～M16, and square head length is 70mm, and the square head length of side is between the large footpath of screw rod and path.
The clamping action of described V-shaped groove clamping plate and flat fishplate is that the V-shaped groove clamping plate are fixed on the platform, promotes flat fishplate by the clamping hydraulic cylinder and realizes clamping action.
Description of drawings
Fig. 1 is the structural representation of the processing unit (plant) of square head screw rod of the present invention.
The specific embodiment
Below by drawings and Examples technical scheme of the present invention is described further.
As shown in Figure 1, the processing unit (plant) of square head screw rod of the present invention, consisted of by positioning seat 1, location clamp nut 2, positioning screw 3, flat fishplate 4, V-shaped groove clamping plate 5, clamping seats 6, cubic edger 7, hold-down nut 8, cutting piston rod 9 and cutting fluid cylinder pressure 10, concrete structure and connected mode are: positioning screw 3 is threaded connection and is fixed on the positioning seat 1, and 2 pairs of positioning screws of location clamp nut 3 are reinforced; Four directions edger 7 is fixed on the cutting piston rod 9 by hold-down nut 8; V flat fishplate 4 and shape groove clamping plate 5 are installed on the clamping seats 6, and cutting piston rod 9 is connected with cutting fluid cylinder pressure 10.
Described flat fishplate 4 and shape groove clamping plate 5 form clamp mechanism and are fixed on the partially rear position of workpiece centre.
Square head screw rod process is: change the cubic edger 7 of regulation, unclamp clamp mechanism, workpiece is put into Working position, adjust positioning screw 3 length, clamping work pieces is opened 10 pairs of workpiece of cutting fluid cylinder pressure and is cut.
Adopt the utility model can produce M8～M16, the longest square head screw rod product that reaches 70mm of square head length.
