Abstract

Usage: in mechanical engineering, in particular in automatic transport-loading devices of machine tools and automatic lines. SUMMARY OF THE INVENTION: Parts 7 from store 8 are individually fed into the receiving sleeve 11 of the intermediate receiver and rested with their bottom end on the supporting platform. During rotation of the shaft 3, the profile cam 18 rotates due to the kinematic coupling of the gears 20 and 21. The lever 9 with the part 7, which slides along the bearing pad, will also rotate from the impacting roller 16 of the incident section. When the carrier with the transport chain 5 is rotated by the angle of the support window (at the same time, the cam 18 turns to the same angle and the intermediate receiver with the sleeve 11 and part 7), the part sinks into the carrier 6 of the transport chain 5. With further rotation of the cam 18, two shoulders lever 9 is spring-loaded to return to its original position. 4 il.

Description

The invention relates to mechanical engineering, in particular to automatic transport-loading devices of machine tools and automatic lines.

The aim of the invention is to simplify the design and increase the reliability of the device in operation by reducing the kinematic coupling elements.

Figure 1 shows the proposed device, a General view, section; figure 2 - section aa in figure 1; on fig.Z - section bb in figure 1, the initial position of the intermediate receiver; figure 4 is the same, the return position of the intermediate receiver. , The device comprises a base 1, a rotor 2, having a shaft 3 mounted in the base 1, a drive for rotating the rotor shaft 3

2 (not shown in fig.) Fixed on the shaft

3 star 4 and transport chain 5 with carriers (slots) 6 of parts 7. Vertical magazine 8 is fixed on base 1 in the loading position and is located above rotor 2 on the path of movement of transport chain 5 with carriers 6. Intermediate receiver is made in the form of two shoulders 9 , on one shoulder 10 of which the pickup sleeve 11 is fixed, located on the path of movement of the transport chain 5 with carriers 6, and the bracket 12 with window 13, coaxially on the receiving sleeve 11, and on the other shoulder 14 of the two arms 9 fixed axis 15c 16. Based on The axis 17 is fixed on the periphery of the rotor 2, on which the profile cam 18c is mounted to interact with the roller 16. The intermediate receiver is mounted above the asterisk 4 of the rotor 2 on the shaft 3 and can be rotated relative to the vertical magazine 8 and constantly pressed by the roller 16 to the profile cam 18 spring 19. With profile cam 18 coaxially fixed gear 20, kinematically

associated with gear 21 mounted on shaft 3. On base 1, between the intermediate receiver and the sprocket 4 of the rotor 2, a supporting platform 22 is fixed for parts 7 with a window 23 located on the movement trajectory of the transport chain 5 at an angle from the initial position of the intermediate receiver to the side its movement from the initial position. The bracket 12 has a bearing surface 24 for the parts 7 located with respect to the window 13 in the direction opposite to the movement of the intermediate receiver from the initial position.

The profile of the cam 18 is made without sharp bends so that the pressure angle (at any position of the cam 18 and the intermediate receiver 9) between it and the roller 16 of the shoulder 14 of the receiver does not exceed the limiting one, i.e. to prevent system seizure.

The intermediate receiver roller 16 is constantly in contact with the profile of the cam 18 under the influence of the spring 19. In the initial position of the intermediate receiver-a (FIG. 3), contacting takes place, for example, at point a. Section 25 of cam profile 18 between point a and arbitrary point b has a curve rise that provides kinematically when the cam is rotated by the size of the central angle between points a and b (conventionally, the angle is assumed to be 180 ° in Fig. 3, 4) until the position when the sleeve 11 with the part 7 becomes coaxial with the opening of the platform 22 and the carrier 6 of the chain 5, i.e. on the angle of the window 23 of the supporting platform 22 relative to the initial position of the intermediate receiver 9. The combination accuracy depends on the kinematic connection of the rotor with the cam 18, the ratio of the shoulders of the intermediate receiver 9 and the amount of elevation of the section 25 of the cam 18 between the points a and c.

Section 26 of the profile of the cam 18 between the points in and a (Fig.4) is made with a variable profile decreasing in radius and with further rotation of the cam 18 returns the intermediate receiver 9 to its original position.

To set the intermediate receiver and profile cam to the initial position, the profile cam is installed, for example, by means of a conical connection with the shank 27 of the axis 17, and for smooth running and ease of adjusting the initial position, the cam profile is

Section 25 can be performed in a spiral of Archimedes.

The boot device operates as follows.

Details 7 of vertical store 8

A cut-off device (not shown in Fig.) individually through the window 13 of the bracket 12 is fed into the receiving sleeve 11 of the intermediate receiver and is supported by its bottom end on

bearing pad 22. In the initial position, the intermediate receiver (roller 16) is pressed by spring 19 to profile cam 18 with contact at point a, and carrier 6 is located, for example, coaxially with receiving

sleeve 11.

During the rotation of the shaft 3, the profile cam 18 rotates due to the kinematic coupling of the gears 20 and 21. The impact on the roller 16 of the incident section 25

the cam profile 18 will rotate and the lever 9 with part 7, which at the same time slides along the support pad 22.

When turning the carrier b with the transport chain 5 at the angle of the window 23

Claims (1)

the support pad 22 (at the same time, the cam 18 will turn to the same angle and the intermediate receiver with the sleeve 11 and part 7) the part falls through the window 23 into the carrier of the transport chain 5. With further rotation of the cam 18, the two shoulders lever 9 by the spring 19 tends to return to initial position. The lever 9 pressed against the variable section 26 of the profile cam 18 decreasing in radius rotates in the opposite direction, smoothly approaching its initial position. Claims A loading device comprising a base, a rotor mounted on a shaft, the disk of which is evenly circumferentially located sockets for parts, vertical magazine located above the rotor in the loading position, intermediate receiver located between the magazine and the rotor and made in the form of a two-arm lever, on one arm of which a gripper is installed that can be rotated around the rotor axis by cam kinematically connected to the shaft the rotor, the supporting platform with a window, fixed under the intermediate receiver, is distinguished by the fact that, in order to simplify the design and increase the reliability of the device in operation, the worker the cam profile is made in the form of two convex curvilinear surfaces mated in a plane passing perpendicular to the axis of the rotor shaft. ////////// // ////) (///, eleven ътш S ASTVA //////// ////) (///, T ir “a ZI USh ЈГ S shtgga / iOGGfriL FSh.4
