Description

Technical Field

[0001] The utility model relates to the technical field of fixture switching trolleys, in particular to a fixture switching trolley. Background Art

[0002] At present, due to the increasingly fierce competition in the automotive market, both traditional automotive manufacturers and emerging new energy vehicle manufacturers are trying their best to accelerate the product replacement and seize the market share. However, the planning and implementation of the production line need to follow certain processes and market rules. It is obviously unrealistic to plan a new production line to produce a new model in the short term. This requires that it is best to produce multiple models on one production line as much as possible and reserve space for the introduction of new models, and reserve the ability to quickly introduce new models while producing multiple models on the same production line. In the prior art, the above problems are generally solved by setting up a fixture switching system.

[0003] The structure of the existing fixture switching system generally sets multiple fixture storage positions to store fixtures. The fixture storage positions are fixedly installed on the side of the fixture switching slide. Multiple fixture storage positions can provide fixtures for multiple vehicle models for the production line. Before use, the fixtures need to be placed on the fixture storage. Fixtures are generally heavy. The traditional method is to use manual handling, or use a workshop overhead crane for hoisting, or use a trolley for transportation. Manual handling is laborious and has low efficiency. Using a workshop overhead crane requires special overhead crane equipment, with high investment costs and high costs, and the use range is limited by the travel of the overhead crane. Using a trolley for transportation has poor positioning accuracy and it is difficult to accurately dock with the fixture storage. Summary of the Utility Model

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] Referring to Figures 1-4 , the fixture switching trolley includes a trolley main body and a fixture library 1. A bracket 2 is installed on the trolley main body. The side part of the bracket 2 is in the shape of a right triangle. Two groups of guiding components are installed on the inclined surface of the bracket 2, and the two groups of guiding components are parallel to each other;

[0023] Fixture positioning mechanisms are arranged in the middle of both sides of the bracket 2 for restricting the position of the fixture 15 on the bracket 2;

[0024] Arrival pressing members 4 are installed at both ends of one side of the trolley main body;

[0025] The trolley main body includes a base 5, moving wheels 6 arranged at the four corners of the base 5, and a push rod 7 arranged on one side of the base 5. The arrival pressing member 4 is arranged on the other side of the base 5;

[0026] The guiding component includes a mounting seat 8 installed on the top of the bracket 2 and a bolt-type roller bearing 9 installed on the side of the top of the mounting seat 8;

[0027] When the fixture switching trolley is in use, it is equipped with a fixture library 1 (i.e., a device for storing the fixture 15). A clamping device 10 (such as Figure 2 As shown, the arrival pressing member 4 includes two stainless steel metal sheets with the outer ends bent inward. A rotatable rod body is arranged on the clamping device 10. The rod body is inserted between the two stainless steel metal sheets to form a certain limit (this limit does not need to be locked, as long as the position of the trolley main body can be limited)). In addition, a bracket 2 and two groups of guiding components are also arranged on the fixture library 1 to facilitate the smooth transfer of the fixture 15. Among them, a proximity switch and two clamping cylinders are arranged on the bracket 2 of the fixture library 1. After the fixture 15 arrives, the clamping cylinder clamps the fixture 15;

[0028] Compared with the prior art, the fixture 15 can be transported through the trolley main body. During transportation, the fixture 15 is limited by the fixture positioning mechanism. After docking with the fixture library 1, the fixture 15 moves onto the fixture library 1 through the guiding component. At the same time, in cooperation with the arrival clamping member, the trolley main body can be locked after it arrives, avoiding the shaking of the trolley main body during the movement of the fixture 15, which may cause the fixture 15 to not be transferred smoothly. Compared with the prior art, this device can replace the manual handling and gantry crane handling of the fixture 15, and can accurately and conveniently complete the switching and transportation of the fixture 15 between the fixture library 1.

[0029] In this embodiment, the positioning mechanism of the fixture 15 includes a fixed seat 14 installed on the side of the bracket 2 and a swivel bolt 3 screwed onto the fixed seat 14. By rotating the swivel bolt 3, it can be selected whether to let the swivel bolt 3 pass through the fixture 15 to limit the position of the fixture 15.

[0030] In this embodiment, a guide wheel assembly 13 is installed at the bottom of the base 5. The guide wheel assembly 13 is arranged between two in-place pressing members 4. The guide wheel assembly 13 is rotatably installed on two rows of guide wheels of the base 5. One side of the fixture library 1 is provided with a guide rail 12 that matches the guide wheel assembly 13. When the switching trolley moves to this position, the two rows of guide wheels can move along both sides of the guide rail 12 respectively, ensuring that the movement can be accurately in place.

[0031] In this embodiment, a limit groove 11 is installed at the top of the base 5 to limit the front-back position of the bottom of the fixture 15. Since the bracket 2 and the fixture 15 are both inclined, this prevents the bottom end of the fixture 15 from sliding forward when the fixture 15 moves.

[0032] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
