Description

Motor base

Technical Field

The utility model relates to a motor cabinet that is used for motor installation in the electromechanical field.

Background

The motor is the most common power device, and a corresponding motor base is required to be equipped when the motor is installed. In the field of belt transmission, a common arrangement mode is that a belt pulley is fixed on a motor shaft of a motor, a follow-up belt pulley is further arranged, a belt is wound on the two belt pulleys, the belt pulley on the motor drives the belt to perform transmission, if the center distance between the two belt pulleys is too large, the belt is seriously abraded, and if the center distance between the two belt pulleys is too small, the tension force is insufficient, so that the problem of slipping is easily caused.

Therefore, the position of the belt pulley on the motor can be adjusted, and to achieve the purpose, chinese patent CN207053305U discloses an adjustable motor base, which includes an upper mounting plate and a lower mounting plate, the front portions of the mounting plate and the support plate are connected by a connecting pin extending along the left-right direction through an axis, the rear portions of the mounting plate and the support plate are connected by a connecting screw rod, a nut is arranged on the upper side of the mounting plate on the connecting screw rod, and a spring is sleeved on the connecting screw rod between the support plate and the mounting plate. The mounting plate is provided with a bolt hole for mounting the motor, when the motor adjusting device is used, the motor is mounted on the mounting plate through the bolt, when the position of a motor shaft of the motor needs to be adjusted, the nut is screwed upwards, and under the pushing action of the spring, the angle of the motor can be changed, so that the upward position of the motor shaft of the motor is adjusted; the downward position adjustment of a motor shaft of the motor can be realized by screwing the nut downwards. The existing motor base has the following problems: the motor can produce certain vibration at the course of the work, and in prior art, the vibration that whole motor cabinet rear portion received is by the spring buffering, therefore whole vibrations of motor all can act on the connecting pin that the position leans on in front, and the shearing force that the connecting pin bore is great, is cut very easily, leads to the life of motor cabinet to be limited.

Disclosure of Invention

An object of the utility model is to provide a motor cabinet to solve among the prior art technical problem that the connecting pin receives great motor vibration and is cut off easily.

In order to solve the technical problem, the utility model provides a technical scheme as follows:

the utility model provides a motor cabinet, include the lower part support and set up the upper portion support on the support of lower part through the spring fluctuation, the upper portion support is including the mounting panel and the backup pad that set up from top to bottom, the connecting pin that the front end of mounting panel and backup pad extends along left right direction through articulated axis is connected, the rear end of mounting panel and backup pad is passed through connecting screw and is connected, connecting screw's lower extreme links to each other with the backup pad, connecting screw's upper end runs through the mounting panel along upper and lower direction, connecting screw is last to have adjusting nut in the upper and lower both sides threaded.

The lower end of the connecting screw rod is connected with the supporting plate through a spherical hinge structure.

The mounting plate is provided with a long hole which is used for realizing the extension of the length penetrated by the upper end of the connecting screw rod along the front-back direction.

The spring has four, and four springs are all worn to be equipped with the guide bar in four angles departments of upper portion support and lower part support respectively top mounted in each spring, and the lower extreme and the lower part support of guide bar are fixed, and the upper end of guide bar is worn out by the backup pad upside, has stop nut in the upside threaded connection of backup pad on the guide bar.

The utility model has the advantages that: when the motor is used, the motor is installed on the installation plate of the upper support, when the angle of the installation plate needs to be adjusted, the angle of the installation plate is adjusted through the adjusting nuts on the upper side and the lower side of the installation plate, after the adjustment, the position of the installation plate is fixed through the adjusting nuts, therefore, the installation plate, the support plate, the connecting screw rod and the connecting pin form an integral structure, vibration generated when the motor works is transmitted to the lower support from the upper support integrally, the vibration is born by the spring, and the connecting pin is prevented from being cut off due to excessive shearing force.

fig. 2 is a top view of the mounting plate of fig. 1.

Detailed Description

An embodiment of a motor base is shown in fig. 1 ~ 2, which comprises a lower support 5 and an upper support arranged on the lower support in a floating manner up and down through four springs, the upper support comprises an installation plate 2 and a support plate 3 arranged up and down, the front ends of the installation plate 2 and the support plate 3 are connected with each other through a connecting pin extending along the left-right direction through a hinge axis, the rear ends of the installation plate 2 and the support plate 3 are connected with each other through a connecting screw rod 2, the lower end of the connecting screw rod is connected with the support plate 3 through a ball hinge structure, the ball hinge structure comprises a ball seat fixed on the support plate and a ball head 11 rotatably assembled in the ball seat, the ball head 11 is welded and fixed at the lower end of a connecting screw rod 12, the ball seat comprises a lower ball seat part 8 with a ball groove 9 and a ball seat cover 10 fixed at the upper end of the lower ball seat part through a screw, the ball head 11 is rotatably assembled in the ball groove 9, the ball seat cover is provided with an annular hole 17 for the connecting screw rod to pass through, the annular hole 17 of the ball seat is arranged from top to bottom, the installation plate 2 is provided with a long hole 16 for the upper end of the connecting screw rod to pass through, the upper end of the connecting screw rod, the long hole 16 is arranged on the installation plate, the upper end of the upper support plate, the upper end of the upper support 6, the upper support is connected with a nut.

During the use through wear to adorn the bolt with the motor and install on the mounting panel in the bolt perforation, the axis of the motor shaft of motor extends the setting along left right direction, when needing the angle of adjustment mounting panel, realizes through revolving the adjusting nut who revolves the upper and lower both sides of mounting panel, after mounting panel angular adjustment, realizes the fixed of mounting panel through adjusting nut. The spherical hinge structure and the long hole can be well matched with the angle adjustment of the mounting plate, and the problem of stress concentration is avoided. After the angle of the mounting plate is adjusted, the mounting plate, the supporting plate, the connecting pin and the connecting screw rod form an integral structure, vibration generated by the motor is transmitted downwards through the integral upper support and borne by the four springs, the problem that the connecting pin is easily sheared due to vibration shearing force is avoided, and the service life of the motor base is ensured.
