Abstract
The utility model discloses a tensioning device with a bandsaw transmission belt, which comprises a slide plate, a tensioning screw rod, a rocker arm and a connecting rod body, wherein one end of the tensioning screw rod and the slide plate are connected through a tensioning axle, the other end of the tensioning screw rod is connected with the rocker arm, and the slide plate and the connecting rod body are connected through a pin. The utility model adopts the scheme that the tensioning or loosening of the transmission belt is achieved by adjusting the size of the center distance of the drive pulleys on a drive pulley and a sawblade pulley, thereby having less parts, simple structure, low cost and convenient operation.
Description
Technical field
The utility model relates to a kind of electric cutting tool of mechanical field, is specifically related to a kind of swelling device of band saw driving-belt.
Background technology
Band saw is widely used in mechanical field, can be used to materials such as cutting metal, timber, plastic plate and fiberboard.Band saw generally is provided with transmission device, i.e. motor drives actuator movement, and transmission device drives the saw blade belt wheel and rotates and then drive saw blade motion (perhaps transmission device directly drives saw blade motion).The driving-belt of transmission device is generally belt or polywedge bet, needs in the course of the work driving-belt is carried out tensioner or lax.Existing driving-belt swelling device complex structure, cost is higher.
The utility model content
Goal of the invention:, the utility model proposes a kind of swelling device of simple in structure, easy to operate band saw driving-belt in order to overcome the deficiencies in the prior art.
Technical scheme: the swelling device of band saw driving-belt of the present utility model comprises slide plate, tensioner screw rod, rocking arm and gonnecting rod body, and tensioner screw rod one end is connected by tension shaft with slide plate, and the tensioner screw rod other end is connected with rocking arm, and slide plate is connected by pin with gonnecting rod body.
The swelling device of band saw driving-belt of the present utility model is installed in the tensioner guard shield on the body, connecting rod contacts with drive pulley, the drive pulley that is installed on the motor is connected by driving-belt with drive on the saw blade belt wheel, when needing to relax driving-belt, shake rocking arm, drive the tensioner screw motion, and then the drive slide plate moves to the rocking arm direction in the horizontal direction, the drivening rod body that moves horizontally of horizontal slide plate compresses drive pulley, the centre-to-centre spacing of the drive on drive pulley and the saw blade belt wheel is reduced, and driving-belt is lax like this; Shake rocking arm in the other direction, the tensioner screw rod drives slide plate and moves away from rocking arm in the horizontal direction, and the centre-to-centre spacing of the drive on drive pulley and the saw blade belt wheel increases, and makes the driving-belt tensioner.
Beneficial effect: the swelling device number of parts of band saw driving-belt of the present utility model is few, simple in structure, cost is low, easy to operate.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is installed in schematic diagram on the band saw body for the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
As illustrated in fig. 1 and 2, the swelling device of band saw driving-belt of the present utility model comprises slide plate 1, tensioner screw rod 2, rocking arm 3 and gonnecting rod body 4, tensioner screw rod 2 one ends are connected by tension shaft 5 with slide plate 1, and tensioner screw rod 2 other ends are connected with rocking arm 3, and slide plate 1 is connected by pin 6 with gonnecting rod body 4.
The utility model is installed in the tensioner guard shield 10 on the body, connecting rod 4 contacts with drive pulley 7 on being installed in motor 11, drive pulley 7 is connected by driving-belt 8 with drive on the saw blade belt wheel 9, when needing to relax driving-belt 8, shake rocking arm 3, drive 2 motions of tensioner screw rod, and then drive slide plate 1 moves towards rocking arm 3 in the horizontal direction, the drivening rod body 4 that moves horizontally of slide plate 1 compresses drive pulley 7, the centre-to-centre spacing of the drive on drive pulley 7 and the saw blade belt wheel 9 is reduced, and driving-belt 8 is lax like this; Shake rocking arm 3 in the other direction, tensioner screw rod 2 drives slide plate 1 and moves away from rocking arm 3 in the horizontal direction, the centre-to-centre spacing of the drive on drive pulley 7 and the saw blade belt wheel 9 increases, and makes driving-belt 8 tensioners. and the swelling device number of parts of band saw driving-belt of the present utility model is few, simple in structure, cost is low, easy to operate.
The above only is a preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
