Description

Technical Field

[0001] The invention relates to the technical field of flipping equipment, and in particular to a flipping mechanism. Background Art

[0002] In industrial production and various engineering applications, the flip mechanism plays an indispensable role as a key device to achieve the transformation of the object's posture. Traditional flip mechanisms have exposed many problems that need to be solved in long-term practical applications. Their structural design is often relatively simple, usually only having basic flipping functions, which makes it difficult to meet the increasingly diverse production process requirements. From the flipping perspective, traditional flipping mechanisms generally have unsatisfactory flipping angles. In many actual operation scenarios, objects need to be flipped at a large angle. However, traditional mechanisms are limited by their own structure and drive mode, making it difficult to achieve a large flip angle, which seriously restricts their application in some tasks that require a high flipping angle. For example, in the assembly of large workpieces, the processing and positioning of complex parts, and other links, due to insufficient flipping angles, additional auxiliary equipment or repeated operations are often required, which not only reduces production efficiency, but also increases production costs and operational complexity. In addition, the traditional flipping mechanism also has obvious defects in terms of space occupation. Its flipping process often requires a large space range to complete the action, which can still meet the use requirements in open areas with unconstrained space. However, in some specific occasions, such as narrow workshop aisles, compact experimental equipment, and internal equipment installation areas of ships and aircraft with limited space, the shortcomings of the traditional flipping mechanism are large in size and large flipping space. In these small space environments, the traditional flipping mechanism cannot even be installed and used normally, which greatly limits its scope of application. With the rapid development of modern industry, higher requirements are placed on the efficiency, flexibility and spatial adaptability of equipment. In many industries, there is an urgent need for a new type of flipping equipment that can overcome the shortcomings of traditional flipping mechanisms to meet the needs of precise flipping operations with short drive stroke, large flipping angle and small space occupation in complex spatial environments.

[0030] Wherein, the first slide groove 112 and the second slide groove 116 are both T-shaped slide grooves.

[0031] The use state of the present invention is as follows: the present invention has a reasonable and simple structure, low production cost and convenient installation. Initially, the base 1 is firmly placed on the working plane to provide stable support for the entire flip mechanism. The connecting seat 2 is firmly fixed to the center of the upper side of the base 1, playing a key role in connecting the various components. The supporting seat 3 is located on the upper left side of the connecting seat 2, which is fixedly connected to the support 4. The upper side of the support 4 is movably connected to the outer center of the cylinder 5. The cylinder 5 is in the initial contraction state. The adjustable limit mechanism 6 is installed inside the rear side of the connecting seat 2, wherein the adjustment mechanism 61 is in a standby state, the motor 611 is not started, the screw 612 is stationary, the arc slider 63 is located in the arc guide hole 62, and remains stationary in the initial position, and the connecting block 64 is connected to the outer side of the connecting shaft 7 at the rear side. The two buffers 66 and the limit block 65 are respectively arranged at the end positions of the arc slider 63 and the mounting seat 12, which are in an untriggered state. The left side of the mounting seat 12 is fixed to the right side of the connecting seat 2. The connecting shaft 7 is movably connected to the upper side of the mounting seat 12, and its rear side is connected to the connecting block 64. The outer and inner parts of the lower left side of the flip seat 9 are movably connected to the upper center of the mounting seat 12 and the connecting shaft 7, respectively, and are in a horizontal initial position. The support 2 8 is fixed to the upper left side of the flip seat 9 and is hinged to the end of the piston rod on the right side of the cylinder 1 5. The rotating transmission mechanism 10 is installed inside the flip seat 9. The motor 2 101 is not started. The driving gear 102, the transmission end gear 103, the transmission gear 1 104, the transmission gear 2 105, the transmission gear 3 106 and the transmission shaft 1 07 are all in a stationary state, the clamping device 11 is connected to the right side of the rotating transmission mechanism 10, the movable seat 111 is fixed to the rotating transmission mechanism 10, the cylinder 1 113 and the cylinder 2 117 are in an initial contracted state, the clamping block 1 114 and the clamping block 2 115 are respectively located at the initial positions of the slide slot 1 112 and the slide slot 2 116, and no object is clamped. When it is necessary to clamp the object, the cylinder 1 113 and the cylinder 2 117 in the clamping device 11 are started, and the piston rods on both sides of the cylinder 1 113 extend to push the corresponding clamping block 1 114 to move outward in the slide slot 1 112, and the piston rods on both sides of the cylinder 2 117 extend to push the corresponding clamping block 2 115 to move outward in the slide slot 2 116, and then the object is placed between the two clamping blocks 114. and the two clamping blocks 115, and then the two clamping blocks 114 and the two clamping blocks 115 are clamped together by shortening the cylinder 113 and the cylinder 2 117, and then the object can be processed.

Since the lower left side of the flip seat 9 is movably connected with the mounting seat 12 through the connecting shaft 7, under the action of the oil cylinder 15, the flip seat 9 starts to rotate counterclockwise around the connecting shaft 7. When it is necessary to accurately limit the flip angle, the motor 1 611 in the adjustment mechanism 61 is started, and the motor 1 611 drives the screw 612 to rotate. The screw 612 cooperates with the movable block 617 through the ball 618 to make the movable block 617 move in the guide groove 616.Then, the guide groove seat 615 and the arc slider 63 are driven to move in the arc guide hole 62, thereby adjusting the position of the arc slider 63 in the arc guide hole 62, so as to change the limit position of the upper limit block 65.

In addition, the right side of the connecting block 64 is movably connected to the outside of the connecting shaft 7, thereby ensuring that the arc slider 63 can rotate around the center of the connecting shaft 7 as a whole, thereby ensuring that the buffer 66 and the limit block 65 are adjusted with the flip seat 9 The reliability and stability of the contact, in addition, the motor 2 101 in the rotating transmission mechanism 10 can be started as needed, the motor 2 101 drives the driving gear 102 to rotate, the driving gear 102 drives the transmission end face gear 103 to rotate, the transmission end face gear 103 drives the transmission gear 2 105 to rotate through the transmission gear 1 104, and the transmission gear 2 105 drives the transmission gear 3 106 to rotate, and finally the transmission shaft 107 drives the clamping device 11 and the clamped object to rotate synchronously during the flipping process, thereby meeting the processing needs at different flipping angles.
