Description

Technical Field

[0001] The present invention relates to the field of HUB assembly and processing, and in particular to a novel flip structure. Background Art

[0002] In the hub assembly line, a new structure is used in a hub upper shell assembly device. Its main function is to complete the hub flip 180 degrees and then accurately fix the product, so that the equipment can accurately screw the front and back sides simultaneously. Traditional flipping structures generally clamp the module, flip it 180 degrees, and then return it to its original position, or add multiple cylinders to the rotating mechanism to clamp it, and then use cylinders or servos to drive the flip;

[0003] The above flipping structure is very expensive, occupies a large space, is not convenient for clamping, positioning and flipping, and is difficult to change the fixture when the production line produces different models of products. It is not economical and has low efficiency. Summary of the Invention

[0004] The main purpose of the present invention is to provide a new type of flip structure, which can effectively solve the technical problems raised by the background technology.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] A novel flip structure comprises a set of first X guide rails, a set of second X guide rails and a set of first Y guide rails, a set of first X guide rails having a first base plate and a first buffer movably mounted on the top of the set of first X guide rails, a flip connecting plate fixedly mounted on the top of the first base plate, a flip connecting shaft and a left clamping fixture mounted on the inner side of the flip connecting plate, a reducer and a flip servo motor mounted on the outer side of the flip connecting plate, a left clamping fixture mounted on one end of the reducer output shaft, a linear bearing mounted on the inner side of the flip connecting shaft, a set of second X guide rails having a second base plate movably mounted on the top of the set of second X guide rails, The same flip connecting plate is movably installed on the inner side of the second base plate, and a right clamping jig is movably installed on the inner side of the flip connecting plate in the second base plate. The left clamping jig and the right clamping jig are connected to the flip connecting plate through a first quick-change knob. Flip synchronous wheels are movably installed between the two first X-guide rails in a group and between the two second X-guide rails in a group. The outer periphery of the two flip synchronous wheels is sleeved with a flip synchronous belt. A second connecting block is fixedly connected between the bottom of the first base plate and the second base plate and the flip synchronous belt, and a tensioning block is installed on the outer end of the rotating shaft of one of the flip synchronous wheels.

[0007] As a further solution of the present invention, the end of the linear bearing is connected to the flip connecting plate in the second base plate, and the two flip connecting plates are fixedly installed with the left clamping fixture and the right clamping fixture respectively.

[0008] As a further solution of the present invention, the left clamping fixture and the corresponding flip connecting plate are fixedly connected to the output shaft of the reducer, and the right clamping fixture and the corresponding flip connecting plate are movably rotatably arranged on the top of the second base plate through the flip shaft.

[0009] As a further solution of the present invention, the first base plate and the second base plate are respectively slidably arranged through a set of first X-direction guide rails and a set of second X-direction guide rails, and the first base plate and the second base plate are both fixedly connected to the flip synchronous belt through a second connecting block.

[0010] As a further solution of the present invention, a clamping assembly is installed between the first base plate and the top of the second base plate, and the clamping assembly includes two groups of first Y-guide rails, and the two groups of first Y-guide rails are installed between the top of the first base plate and the second base plate, and the third base plate and the fourth base plate are movably installed on the top of the two groups of first Y-guide rails, a front positioning fixture is fixedly installed on the top of the third base plate, and a rear positioning fixture is installed on the inner side of the fourth base plate, and first positioning wheels are movably installed between the two groups of first Y-guide rails, and the outer peripheries of the two first positioning wheels are sleeved with the same flipping synchronous belt, and the third connecting block and the first connecting block are respectively connected and installed between the bottom of the third base plate and the fourth base plate and the flipping synchronous belt, a positioning cylinder is installed on one side of the third base plate and the fourth base plate, and a second buffer is installed on the end of the positioning cylinder.

[0011] As a further solution of the present invention, the third base plate and the fourth base plate are located on the top of the second X-guide rail and are slidingly arranged. The rear positioning fixture and the front positioning fixture are respectively connected to the fourth base plate and the third base plate through the second quick-change knob.

[0012] As a further solution of the present invention, the bottom of the third base plate is fixedly connected to the flip timing belt via a third connecting block, and the bottom of the fourth base plate is fixedly connected to the flip timing belt via a first connecting block.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] By setting up a flip servo motor, a flip connecting plate, and a flip connecting shaft, the left clamping fixture and the right clamping fixture clamp the product longitudinally. The flip servo motor drives the left clamping fixture and the right clamping fixture to rotate 180 degrees, which can clamp the product longitudinally and laterally, completing the positioning and flipping of the product;

[0015] By setting up the front positioning fixture and the rear positioning fixture, the product will swing slightly after flipping due to the gear clearance of the reducer itself, which will have a great impact on screw driving, making it easy to drive the screw off-center or get stuck. However, this new mechanism adds a clamping device after flipping, eliminating this swing clearance, thereby greatly improving the accuracy after flipping and meeting the needs of precision screw driving.

[0016] By setting up the clamping assembly, when producing different models of products on the production line, you only need to open the first and second quick-change knobs on the left clamping jig, right clamping jig, front positioning jig, and rear positioning jig, remove the jig plate, and replace the new corresponding jig plate to complete the model change. The model change is convenient and fast, greatly saving the production line model change time.

[0017] The new flip structure of the present invention has a simple structure, occupies little space, and can be quickly changed according to different product jigs, greatly improving the efficiency of the production line. In addition, the new flip mechanism can also expand other similar product assembly equipment that requires flip assembly, so it has great market prospects. BRIEF DESCRIPTION OF THE DRAWINGS
