Abstract

The utility model discloses a transfer arm. The transfer arm comprises an installing seat, an air cylinder, a synchronous belt pressing plate, a short synchronous belt wheel set, a floating connector, a driving gear, a long synchronous belt wheel set, a driven gear, a long synchronous belt pressing plate and a sliding block fixing plate. The short synchronous belt wheel set is connected with the long synchronous belt wheel set through the gear set, the cylinder body of the air cylinder is fixed on the installing seat, the rod end of a piston rod of the air cylinder is connected with the short synchronous belt pressing plate, the short synchronous belt pressing plate is connected to a short synchronous belt of the short synchronous belt wheel set in a clamping mode, and the long synchronous belt pressing plate is connected to a long synchronous belt of the long synchronous belt wheel set in a clamping mode and fixedly connected with the sliding block fixing plate. Due to the fact that the short synchronous belt wheel set and the long synchronous belt wheel set are arranged, and the driving gear and the driven gear are connected with the short synchronous belt wheel set and the long synchronous belt wheel set respectively, the gear ratio of the driving gear to the driven gear is larger than 1, then the large shift motion of the sliding block fixing plate can be driven due to the short shift motion of the piston rod of the air cylinder, therefore, the air cylinder is installed in the installing seat, and the size of the whole mechanism is reduced.

Description

Transporting arms

Technical field

The utility model relates to a kind of machinery, particularly relates to a kind of transporting arms.

Background technique

In machinery, the shift motion of workpiece is that the shift motion by cylinder piston rod determines, the shift motion of workpiece is larger, and the shift motion of cylinder piston rod is also larger, and this just causes the volume of equipment to increase.For this reason, the dealer need to a kind ofly not affect the again little mechanical structure of prerequisite lower volume of stroke.

The model utility content

The purpose of this utility model is to provide the transporting arms that a kind of volume is little, shift motion is long.

For achieving the above object, technical solution of the present utility model is:

The utility model is a kind of transporting arms, and it comprises fitting seat, cylinder, Timing Belt pressing plate, short Timing Belt wheels, floating junction, driving gear, long Timing Belt wheels, driven gear, long Timing Belt pressing plate, slide block fixed plate; Described short Timing Belt wheels are comprised of two short synchronous pulleys, short Timing Belt, two short synchronous pulleys are respectively by rotatable left end and the middle part that is installed in fitting seat of rotating shaft, fitting seat is passed in the rotating shaft that is installed in the short synchronous pulley of left end, and driving gear is fixedly sleeved on the traversing through end of this rotating shaft; Described long Timing Belt wheels are comprised of two long synchronous pulleys, long Timing Belt, two long synchronous pulleys are respectively by rotatable left end and the right-hand member that is installed in fitting seat of rotating shaft, fitting seat is passed in the rotating shaft that is installed in the long synchronous pulley of left end, and driven gear is fixedly sleeved on the traversing through end of this rotating shaft and the engagement of driven gear and driving gear; The cylinder body of described cylinder is fixed in the fitting seat, and the rod end of the piston rod of cylinder connects short Timing Belt pressing plate by floating junction, and short Timing Belt pressure board is connected on the short Timing Belt of short Timing Belt wheels; Described long Timing Belt pressure board is connected on the long Timing Belt of long Timing Belt wheels and is affixed with the slide block fixed plate.

On fitting seat, longitudinally be provided with two parallel guide rails, the upper/lower terminal of described slide block fixed plate slips on these two guide rails.

The gear ratio of described driving gear and driven gear is 2:1.

After adopting such scheme, because the utility model is provided with short Timing Belt wheels and long Timing Belt wheels, and driving gear and driven gear have been attached thereto respectively, gear ratio by driving gear and driven gear are set is greater than 1, just can realize the larger shift motion of shift motion band movable slider fixed plate that cylinder piston rod is shorter, thereby cylinder can be installed in the fitting seat and dwindle the volume of whole mechanism.

Below in conjunction with the drawings and specific embodiments the utility model is further described.

Embodiment

Such as Fig. 1, Fig. 2, shown in Figure 3, the utility model is a kind of transporting arms, and it comprises fitting seat 1, cylinder 2, floating junction 3, short Timing Belt wheels 4, short Timing Belt pressing plate 5, driving gear 6, long Timing Belt wheels 7, driven gear 8, long Timing Belt pressing plate 9, slide block fixed plate 10.

Described short Timing Belt wheels 4 are comprised of two short

synchronous pulleys

41,42, short Timing Belt 43.Two short

synchronous pulleys

41,42 are respectively by rotating shaft 411,421 rotatable left end and the middle parts that are installed in fitting seat 1, and fitting seat 1 is passed in the rotating shaft 411 that is installed in the short synchronous pulley 41 of left end, and driving gear 6 is fixedly sleeved on the traversing through end of this rotating shaft 411.

Described long Timing Belt wheels 7 are comprised of two long

synchronous pulleys

71,72, long Timing Belt 73.Two long

synchronous pulleys

71,72 are respectively by rotating shaft 711,721 rotatable left end and the right-hand members that are installed in fitting seat 1, fitting seat 1 is passed in the rotating shaft 711 that is installed in the long synchronous pulley 71 of left end, and driven gear 8 is fixedly sleeved on the traversing through end of this rotating shaft 711 and driven gear 8 and driving gear 6 engagements.Driving gear 6 can be decided according to needs with the gear ratio of driven gear 8, and in the present embodiment, driving gear 6 is 2:1 with the gear ratio of driven gear 8, and the number of teeth is respectively 60 and 30.

The cylinder body of described cylinder 2 is fixed in the fitting seat 1, and the rod end of the piston rod of cylinder 2 connects short Timing Belt pressing plate 5 by floating junction 3, and short Timing Belt pressing plate 5 is connected on the short Timing Belt 43 of short Timing Belt wheels 4.Described long Timing Belt pressing plate 9 is connected on the long Timing Belt 73 of long Timing Belt wheels 7 and is affixed with slide block fixed plate 10.

Working principle of the present utility model:

The piston rod of cylinder 2 moves by the short Timing Belt 43 that short Timing Belt pressing plate 5 drives short Timing Belt wheels 4, thereby drive driving gear 6 rotations with short synchronous pulley 41 coaxial settings, driving gear 6 drives the driven gear 8 that is engaged with and rotates, the long synchronous pulley 71 that driven gear 8 drives with it coaxial setting rotates, and then the long Timing Belt 73 of driving moves with the slide block fixed plate 10 that is fixed on the long Timing Belt 73.Because driving gear 6 is 2:1 with the gear ratio of driven gear 8, the travelling speed of slide block fixed plate 10 will be 2 times in the piston rod of cylinder 2.

Emphasis of the present utility model just is: be connected by gear train between short Timing Belt wheels and the long Timing Belt wheels.
