Description

Technical Field

[0001] The invention relates to a production line device, in particular to a multifunctional flexible production rapid positioning system. Background Art

[0002] Due to the diversification of modern production products, it is necessary to constantly change the logistics workstations and adjust them during the production process. The building block components can be constructed into almost all kinds of medium and light workstations. Through simple design, the production of lean material handling systems has good flexibility, allowing users to design, build and adjust the actual template of the production line according to their special needs. Traditional production lines use fixed installation positions, and when changing the production of different templates, a large number of production line structures need to be replaced.

[0003] The Chinese patent number is CN207155072U, and the publication date is March 30, 2018. The name of the invention is a flexible switching platform for body fixtures. Specifically, a flexible switching platform for body fixtures is disclosed, which is used for a trial production line based on a two-layer steel structure platform. The first layer of the two-layer steel structure platform is provided with a body assembly station. The flexible switching platform for body fixtures is arranged at the body assembly station, including two flexible mounting plates, and the two flexible mounting plates are respectively provided with parallel tracks and symmetrical positioning holes arranged along the track direction. Multiple flexible switching mechanisms are installed between the two flexible mounting plates through the tracks and positioning holes. The flexible switching mechanisms are flexibly switched on the flexible mounting plates to achieve the clamping and fixing of different car body models. Its shortcomings are that it still cannot meet the rapid switching of processing between different products, and it is suitable for the production of large quantities of products. For small batches of products, the switching efficiency is low. Summary of the invention

DETAILED DESCRIPTION

[0031] The technical solution of the present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0032] Example 1

[0033] like Figure 1 , Figure 2 and Figure 3As shown, the multifunctional flexible production rapid positioning system comprises: a servo motor 1, a servo motor seat 2, a transmission base 3, a transmission mechanism 4, a transmission guide rail 5 and a reference transmission platform 6. The transmission guide rail 5 is arranged on the top of the transmission base, the servo motor seat 2 is installed on the side of the transmission base, the transmission mechanism 4 is arranged in the transmission base, the servo motor 1 is installed on the servo motor seat 2, and the rotating shaft of the servo motor drives the transmission mechanism 4.

[0034] A groove is arranged in the middle of the upper part of the transmission base. The transmission mechanism 4 adopts a ball screw structure. Both ends of the ball screw are installed in the groove of the transmission base through bearings. The servo motor seat is arranged at the end position of the groove. The ball screw is connected to the servo motor 1 in transmission.

[0035] There are two transmission guide rails, which are fixed at the top positions on both sides of the groove. The transmission guide rails are equipped with sliders, which are fixedly connected to the reference transmission platform 6.

[0036] The reference transmission platform 6 is a square structure, and a transmission sleeve is fixed in the middle position below the reference transmission platform, and the transmission sleeve cooperates with the ball screw.

[0037] The top of the reference transmission platform is equipped with three positioning plates 8, which are detachably connected to the reference transmission platform 6. Six circular positioning holes are provided on the reference transmission platform 6, and the positioning holes are grouped in pairs. The center line of the positioning holes in the same group is perpendicular to the long side axis of the transmission base 3. Two positioning pins 11 are provided on each positioning plate 8, and the two positioning holes in each group correspond to the two positioning pins on one positioning plate.

[0038] A press-operated telescopic switch 7 and a locking structure 13 are provided on the side of the reference transmission platform 6;

[0039] The locking structure 13 passes through the positioning hole of the reference transmission platform 6 , with a first end fixedly connected to the movable end of the press-operated telescopic switch 7 , and a second end fixedly connected to the reference transmission platform 6 ; the locking structure 13 cooperates with the rapid positioning mechanism 10 .

[0040] A quick positioning mechanism 10 is installed in the positioning hole. Figure 4 The quick positioning mechanism 10 shown is a sleeve made of a flexible material, the outer diameter of the sleeve matches the positioning hole, and the inner diameter of the sleeve matches the positioning rivet 11 .

[0041] Two arc plates 12 installed in an "eight" shape are arranged in the sleeve of the quick positioning mechanism 10 ; the arc plates 12 are integrally formed with the sleeve.

[0042] The main function of the arc plate 12 installed in the shape of an eight is to enable the top surface of the sleeve to be pulled downward when the quick positioning mechanism 10 is tightly held by the locking structure 13, and the rivet hole in the middle of the sleeve can lock the rivet and pull the rivet downward at the same time.

[0043] Two positioning pins 11 are installed at the bottom of each positioning plate 8, and the center distance between the two positioning pins 11 matches the center distance of the same group of positioning holes;

[0046] The end of the pull column is conical;

[0047] The positioning rivet 11 cooperates with the quick positioning mechanism 10. The positioning rivet 11 adopts a structure similar to that of an expansion screw. When the bottom end of the pull column is held and pulled by the quick positioning mechanism 10, the cone at the end is pulled down together, and the cone at the end simultaneously opens the inverted T expansion structure, so that the inverted T expansion structure fixes the positioning plate 8.
