The present invention relates to a speed distribution apparatus for a direct motion mechanism for a robot, and more particularly, to a speed distribution apparatus for a direct motion mechanism to enable a simple and reliable structure for implementing a double speed.

As a conventional speeding device for a linear motion mechanism, it is proposed as Utility Model Registration Application No. 93-2161, which is the applicant's prior application.

As shown in FIG. 1, the driving force of the motor 41 provided through the partition wall 41 of the body 40 is applied to the rotation shaft 421 provided at a predetermined interval in the partition wall 401. It is delivered by pulleys 411 and 425 and belt 411A. As a result, the rotational force transmitted to the rotary shaft 421 is transmitted to the rotary gears 424, 424A, 423 and 423A connected to the belts 424 and 424A on both sides of the rotary shafts 421 and 421A. Each of the positioning bodies 431 and 431A fixed to the fastening bolts 424) and 424A is configured to be transported from side to side.

This configuration has a problem that the power transmission means and the rotation means consists of a number of stages, the number and complexity of the parts, and the lack of reliability can not be obtained according to the assembly state.

The present invention has been made in view of the above problems, the object of the present invention is to provide a double speed mechanism of the linear motion mechanism for the robot to implement a simple and reliable double speed by configuring a small number of parts.

The present invention has a drive unit having a body having a partition wall on both sides, a power transmission member supported on both side pulleys of the body to orbital movement as a power source, and in both space portions by the drive unit, Characterized in that it consists of a transfer unit provided with a positioning body for transferring in the direction opposite to each other.

Hereinafter, embodiments of the present invention will be described in detail by the accompanying drawings.

Figure 2 (a) is an overall perspective view of the device to which the present invention is applied, this speeding device is composed of a horizontal transfer member (X), a vertical transfer member (Y) and a linear motion transfer member (Z).

Among the transfer members, the linear motion transfer member Z according to the present invention forms a partition wall 11 having a predetermined thickness in the middle, as shown in FIG. It is composed of a body (10) provided.

A motor 22 and a speed reducer 23 supported in one housing 21 of the body, and the pulley 24 joined to the speed reducer is rotatable to a bearing 26 in the housing 21A on the other side. The provided pulley 25 is provided with drive parts 20 and 20A which are connected to each other by a power transmission member 26 such as a belt or a chain.

Positioning bodies 40 and 40A, which are inherent in both side space portions 12 and 12A of the body 10, are fastening members 31 and 31A, respectively, on both sides of the power transmission member 26 passing through the space portion. And the support members 32 and 32A formed on both sides of the positioning bodies 40 and 40A are slidably coupled to the guide members 33 and 33A so that the positioning member is a power transmission member 26. The transfer unit (30) (30A) are respectively transferred according to the rotation direction of the.

Then, the positioning body 40 located in the one side transfer unit 30 is fixed to the vertical transfer member (Y).

According to the present invention having such a configuration, the driving of the motor 22 is decelerated at a predetermined rotational speed by the speed reducer 23 by applying power, so that the pulley 24 connected to the speed reducer 23 and the housing 21A on the other side are reduced. Rotate the power transmission member 26 to connect the pulley 25 is located. Accordingly, the positioning body 40 of one side fixed to the fastening member 31 at one side of the power transmission member 26 is transferred to either side on the body 10 as shown in FIG. One side positioning body 40 is fixed to the vertical transfer member (Y), so that the body 10 is relatively relatively conveyed, the transfer distance (l1) is generated.

On the other hand, the positioning body 40A fixed to the other side of the power transmission member 26 is transported as opposed to the positioning body 40A which is conveyed by the distance L1 by the orbital movement of the power transmission member, and thus the transport distance L2 is generated. Therefore, the overall conveying distance l1 (l2) becomes the sum of l1 and l, which is the conveying distance of each positioning body 40 (40A), that is, L, and a linear motion at double speed can be obtained by this total conveying distance (L). It can be.

This invention devises the motor's driving speed by simply reducing the motor's drive without the need to reduce and transfer the motor's drive through various rotation means, so the parts are drastically reduced. There is an effect that can improve the reliability of.
