Abstract
The invention belongs to the field of calendaring equipment, and particularly relates to a triangular fixing mechanism for a rotary bending stretcher. The mechanism comprises a connecting base fixedly connected with a machine frame of the stretcher, a first clamping jaw and a second clamping jaw in rotary connection with the connecting base and a locking mechanism making the first clamping jaw and the second clamping jaw relatively locked, wherein end parts, away from a rotary shaft, of the first clamping jaw and the second clamping jaw are provided with receiving grooves receiving a part of the main shafts, the first clamping jaw, the second clamping jaw and the connecting base form a triangular structure, and shaft centers of the rotary shafts of the first clamping jaw and the second clamping jaw and the main shaft are three apexes of the triangle respectively. When the mechanism is arranged on the main shaft, the pair of clamping jaws can be expanded in different angles to conveniently replace a forming die of the stretcher, so that the mechanism has the advantages of convenient unlocking, quick disassembly and good directionality and stability.
Description
Technical field
The invention belongs to the rolling equipment field, particularly a kind of triangle fixing mechanism that is used on the rotating bending drawframe.
Background technology
The stretching-machine that is used to make the escalator armrest support generally includes the main shaft that is connected with transmission mechanism, coaxially is arranged on the shaping mould on the main shaft and makes the main folder head of shaping mould at the axial restraint of main shaft, steel plate is bent to form the elevator armrest support at the external peripheral surface of shaping mould, the radius of curvature of shaping mould is determining the curvature and the shape of armrest support, when the higher armrest support of requirement on machining accuracy, often need to be trimmed to repeatedly the radius of curvature of pattern, can meet the demands until its precision, this process is called and repairs a die.
Way commonly used in the prior art is, a breach that main shaft is penetrated will be offered on the shaping mould, and the main folder head of stretching-machine normally is made up of two semicircular jaws, one of them jaw is fixed on the frame of stretching-machine, and another jaw removably is connected on this fixing jaw, both tighten up locking by bolt, thereby shaping mould is fixed on the main shaft.This main folder head is not easy to dismounting, is to mount and dismount by the breach on the shaping mould, yet offers breach on the shaping mould but to bringing no small trouble in the process that repairs a die, and can't process on lathe by clamping such as shaping mould.
Summary of the invention
But the triangle fixing mechanism of rotating bending drawframe that the purpose of this invention is to provide a kind of Fast Installation and dismounting.
The technical solution adopted in the present invention is: a kind of triangle fixing mechanism of rotating bending drawframe, it comprises the Connection Block on the frame that is fixedly connected on stretching-machine, be rotatably connected to first jaw and second jaw on the described Connection Block, make the locking mechanism that locks relatively between described first jaw and described second jaw, end away from turning cylinder on described first jaw and second jaw offers the accepting groove that can accommodate the part main shaft, described first jaw and second jaw and Connection Block form a triangular structure, the turning cylinder of described first jaw and second jaw, and the axle center of main shaft is respectively described leg-of-mutton three summits.
Further technical scheme of the present invention is: described triangle is an isosceles triangle.
Described locking mechanism comprises the screwed hole that is opened on described first jaw, is rotatably connected to the screw on described second jaw, described screwed hole and screw all are positioned at the sidepiece of described accepting groove, and when described locking mechanism locked, described screw was connected with described screwed hole threaded engagement.
On the radial section of main shaft, the bottom land of described accepting groove is circular arc.
The present invention is contained on the main shaft, can make the shaping mould convenient disassembly that is contained on the main shaft, and a pair of jaw can be according to the size that is contained in instrument on the main shaft, the angle that expansible is different; By threaded engagement, can conveniently lock and release between a pair of jaw; In addition, Connection Block is fixed on the frame, and the leg-of-mutton structure of forming between Connection Block and a pair of jaw has more good directionality, more stable.
Description of drawings
Accompanying drawing 1 is the schematic diagram of shaping mould of the prior art;
Accompanying drawing 2 is a stereogram of the present invention;
Accompanying drawing 3 is a front view of the present invention;
Wherein: 1, first jaw; 2, second jaw; 3, turning cylinder; 4, Connection Block; 5, locking mechanism; 6, main shaft; 7, accepting groove; 8, screwed hole; 9, screw; 10, shaping mould.
The specific embodiment
Shown in accompanying drawing 2, accompanying drawing 3, a kind of triangle fixing mechanism of rotating bending drawframe, it comprises Connection Block 4 on the frame that is fixedly connected on stretching-machine, be rotatably connected to first jaw 1 and second jaw 2 on the described Connection Block 4, make between described first jaw 1 and described second jaw 2 locking mechanism 5 of locking relatively.By rotating first jaw 1 and second jaw 2 can be replaced with pattern 10 easily, end away from turning cylinder 3 on described first jaw 1 and second jaw 2 offers the accepting groove 7 that can accommodate part main shaft 6, on the radial section of main shaft 6, the bottom land of accepting groove 7 is circular arc or becomes the V font, when a pair of centre pawl closed up, accepting groove 7 just can be located workpiece exactly like this.
Described first jaw 1 and second jaw 2 and Connection Block 4 form a triangular structure, the turning cylinder 3 of described first jaw 1 and second jaw 2 and the axle center of main shaft 6 are respectively described leg-of-mutton three summits, because the equal in length of first jaw 1 and second jaw 2 is so above-mentioned triangle is isosceles triangle or equilateral triangle.This leg-of-mutton structure has better directionality, more stable.
The above only is preferable feasible embodiment of the present invention, non-ly limits claim of the present invention with this, so the equivalent structure that all utilizations specification of the present invention and accompanying drawing content are carried out changes, all in like manner all is contained in the scope of the present invention.
