[0002] At present, with the continuous development of intelligent manufacturing and robotics technology, robot fixtures will also be continuously upgraded and improved and applied to various work scenarios. Among them, a clamping fixture is usually operated by a fixture, including a base connecting the robot arm and two clamping plates for clamping parts, which is suitable for grasping, flipping, placing and other operations of mechanical parts.

[0003] In the production process of automotive parts, many heavy or large parts need to be transferred from one work area to another. Robotic fixtures can be used to move these parts, replacing manual handling, reducing labor costs, and improving handling efficiency and safety.

[0004] Due to the complex structure of the automobile transmission shell, when using the robot flip fixture to grab, flip and place the transmission on the line body pallet, the robot fixture should have highly accurate positioning and grabbing capabilities, and be able to quickly and accurately complete the task of handling parts, thereby improving the efficiency of the production line. However, the transmission fixtures on the market cannot accurately grab, flexibly flip and stably place the transmission, and the pallet used cannot stably position and support the transmission.

[0005] Currently, no effective solution to the above problems has been found. Summary of the invention

[0006] The technical problem to be solved by the utility model is to propose a transmission flipping fixture for the above-mentioned shortcomings, which can firmly grasp, flip and place.

DETAILED DESCRIPTION

[0027] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings. Those skilled in the art should understand that the following does not constitute a limitation on the protection scope of the utility model.

[0028] Examples, such as Figure 1-Figure 7 As shown, a transmission flipping fixture comprises a base 4 connected to a robot arm, and a first clamping plate 1 and a second clamping plate 2 are provided on the base 4.

[0029] A cylinder 3 is provided between the first clamping plate 1 and the second clamping plate 2; the first clamping plate 1 is fixedly connected to the piston rod of the cylinder 3; the second clamping plate 2 is fixedly connected to the cylinder barrel of the cylinder 3; the first clamping plate 1 is slidably connected to the base 4; the second clamping plate 2 is fixedly connected to the base 4.

[0030] A first long positioning pin 11 and a first short positioning pin 12 are provided on the inner side of the upper end of the first clamping plate 1 ; a second long positioning pin 21 and a second short positioning pin 22 are provided on the inner side of the upper end of the second clamping plate 2 .

[0031] The first long positioning pin 11 and the second long positioning pin 21 are located in corresponding positions; the first short positioning pin 12 and the second short positioning pin 22 are located in corresponding positions.

[0032] The base 4 is fixed with a parallel first guide rail 44 and a second guide rail 43 ; the first clamping plate 1 is arranged on the first guide rail 44 and the second guide rail 43 .

[0033] A first slider 45 and a second slider 46 are fixed to the bottom of the first clamping plate 1 ; the first slider 45 is slidably connected to the first guide rail 44 ; the second slider 46 is slidably connected to the second guide rail 43 .

[0034] The base 4 is provided with a first long groove 42 and a second long groove 42 ; the first guide rail 44 is fixed in the first long groove 42 ; and the second guide rail 43 is fixed in the second long groove 42 .

[0035] The second long groove 42 is connected to two short grooves 47 on the outside; a wedge block 48 is provided in the short groove 47; a trapezoidal movable pin 49 is provided between the wedge block 48 and the second guide rail 43;

[0036] The wedging block 48 and the movable pin 49 cooperate with the screw to wedge the second guide rail 43 so that the second guide rail 43 will not shift during use, thereby ensuring the parallelism of the first guide rail 44 and the second guide rail 43, and at the same time ensuring that the first slider 45 runs along the first guide rail 44 and the second slider 46 runs along the second guide rail 43.

[0037] The transmission tray comprises a first tray 5 and a second tray 6 .

[0038] A first supporting block 53 is provided on the left side of the first tray 5 ; a second positioning column 52 is provided on the right side of the first tray 5 ; a first positioning column 51 is provided on the upper side of the first tray 5 ; a second supporting block 54 is provided between the first positioning column 51 and the second positioning column 52 .

[0039] A third positioning column 61 is disposed at one end of the second tray 6 ; a third supporting block 62 is disposed at the other end of the second tray 6 .

[0040] According to the implementation of the utility model, due to the irregular shape of the transmission housing, the positions of the locating pins provided on the first clamping plate and the second clamping plate match the positions of the locating pin holes of the transmission housing, and the locating pins can be inserted into the corresponding locating pin holes of the transmission housing. Through the extension and retraction of the cylinder piston rod, the first clamping plate is driven to slide on the guide rail of the base, so that the distance between the first clamping plate and the second clamping plate becomes smaller, thereby achieving the clamping of the transmission. In this way, the transmission can be firmly and accurately grasped to prevent the transmission from falling off during the flipping process.

[0041] The two first positioning columns on the first tray of the transmission, the two second positioning columns and the two third positioning columns on the second tray can be respectively inserted into the positioning holes at different angles of the transmission. The second support block on the first tray and the third support block on the second tray are made of polyurethane material, which can not only play a supporting role when placing the transmission, but also effectively prevent the workpiece from being bumped.

[0042] The above is an example of the best implementation of the utility model, and the parts not described in detail are common knowledge of ordinary technicians in this field. The protection scope of the utility model is based on the content of the claims, and any equivalent transformation based on the technical inspiration of the utility model is also within the protection scope of the utility model.
