It is standby.
Background technology
Reinforcing steel bar bending tester, is the equipment for carrying out bending property detection to reinforcing bar, and its operating mechanism mainly includes
One horizontal operation rotating disk rotated under vertical rotation axis effect, reinforcing bar is placed on the registration roller side in the rotating disk center of circle, will
One end clamping arm and telescoping mechanism of reinforcing bar compress, and working roll is mounted in the non-circle centre position on working rotary table surface, reinforcing bar it is another
Adjacent working roll is held, just by bar bending when rotating disk turns round.But existing reinforcing steel bar bending tester needs to connect due to its bottom
Switch through axle, thus its upper surface circle centre position is blind hole for the hole of placement positioning roller, and in general rebar surface has many iron
Rust, with the bending of reinforcing bar, the iron rust above reinforcing bar is just fallen therewith, is fallen into the blind hole for installing registration roller, when clear
When impurity in reason hole includes iron rust therein, it is necessary to whole rotating disk is turned to the iron rust poured out in hole, due to whole
Sabot is very heavy, so needing that just very laborious if clearing up and also people is also easy to injury in whole process；Work as iron rust simultaneously
When falling into this hole, when rotating disk is being rotated, motion of the registration roller in hole, which also has, to be limited, and influences entirely to survey
Examination.
Utility model content
For the deficiency in the presence of prior art, the utility model provides a kind of simple in construction, steel being convenient to clean
Muscle Apparatus for Bending at low-temp.
To achieve the above object, the utility model employs following technical scheme：
A kind of reinforcing steel bar bending tester, including the rack with workbench and driving force part and dial portion, driving
Power part includes being mounted on the motor and decelerator of interior of equipment cabinet, and the output shaft of motor is connected with decelerator, decelerator it is defeated
Shaft passes perpendicularly through workbench and extended to above workbench, and reducer output shaft is connected with workbench by bearing, rotating disk
Part includes registration roller, working roll, rotating disk, bearing, telescoping mechanism and clamping arm, is provided with what is matched with working roll on rotating disk
Through hole, the first groove to be matched at the top of the output shaft with decelerator is provided with rotating disk bottom, and the output shaft of decelerator passes through
First groove is connected with rotating disk；Described clamping arm one end is be hinged to be arranged on bearing, and the other end is connected to by earrings
On stretching structure；The worktable upper surface is provided with first boss, and the boss center is provided with mounting hole, and the bearing is installed on
In mounting hole；The upper surface circle centre position of the rotating disk is provided with second boss, and the second boss is provided with connecting screw；It is described fixed
Position roller is formed by a larger cylinder and one are coaxially connected compared with small cylinder, and the end face center compared with small cylinder is provided with ladder
Blind hole, the ladder blind hole include the large hole to match with second boss and the smaller hole that matches with screw rod and described smaller
Hole is screw.
Compared to prior art, the present invention has the advantages that：Registration roller is by larger cylinder and compared with small cylinder
Coaxially connected formation, and the registration roller is fixed on the upper surface of rotating disk by being threadedly coupled with connecting screw, so from reinforcing bar
The iron rust that face is fallen down just directly falls on rotating disk, that is, facilitates the cleaning of whole rotating disk and be advantageous to whole testing experiment
Smoothly.

Embodiment
As shown in figure 1, a kind of reinforcing steel bar bending tester, including the rack 4 with workbench and driving force part and turn
Disc portion, driving force part include being mounted on the motor 1 and decelerator 2 of interior of equipment cabinet, and output shaft and the decelerator of motor connect
Connect, the output shaft of decelerator passes perpendicularly through workbench and extended to above workbench, and reducer output shaft 3 passes through with workbench
Bearing 5 connects, and dial portion as shown in Figure 3 includes registration roller 8, working roll 7, rotating disk 6, bearing 9, telescoping mechanism 11 and clamping arm
10, the through hole 61 to be matched with working roll is provided with rotating disk, and rotating disk bottom is provided with phase at the top of the output shaft with decelerator
The first identical groove 60, reducer output shaft are connected by first groove with rotating disk, and this is connected as spline connection；It is described
