[0001] The utility model relates to the technical field of assembly, in particular to an assembly device based on a worm gear lifter. Background Art

[0002] The worm gear lifter is a lifting device composed of a housing, worm wheel, worm, screw and other structures. The meshing worm wheel can be driven by turning the worm with a wrench from the outside, and the screw hole in the center of the worm wheel is threadedly connected to the screw, so that the screw can be raised and lowered. The worm gear and worm meshing structure has reverse braking ability, which can prevent the screw from rotating by itself when bearing the weight of the component. It is often used to lift the components to the assembly height during the assembly process.

[0003] In the current parts assembly operation, parts of different shapes need to be lifted, among which the most common are parts with flat bottoms and parts with arc surfaces. The parts are lifted by the flange installed on the screw of the worm gear lifter itself, which is only suitable for parts with flat bottoms. In addition, the lifting action surface is small, and for parts with arc surfaces, the parts are more likely to have radial movement. All of these will lead to a heavy workload for the lifting equipment, low assembly accuracy, and greater difficulty in aligning the translated parts.

[0004] Therefore, in order to solve the above problems, an assembly device based on a worm gear lifter is proposed. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1 and Figure 2 The utility model provides a technical solution: an assembly device based on a worm gear lifter, including a worm gear lifter 2, which is an existing device that can be raised and lowered and adjusted. A support seat 1 is fixedly installed on the lower side of the worm gear lifter 2, and an avoidance hole for passing the screw in the worm gear lifter 2 is opened on the top of the support seat 1.

[0026] A platform 3 is fixedly installed on the upper side of the worm gear lifter 2, and two groups of slideways 4 are symmetrically arranged on the upper side of the platform 3. A base 5 is slidably installed on each group of slideways 4, and the base 5 mainly plays a supporting and force-bearing role. A movable plate 7 is rotatably installed on the upper side of the base 5. The ends of the movable plates 7 that are close to each other are rotatably assembled through a rotating seat 10. A universal ball 6 is installed on the upper side of the movable plate 7. A limit adjustment mechanism 8 is installed between the rotating seat 10 and the platform 3, and the limit adjustment mechanism 8 is located between the two groups of slideways 4; the limit adjustment mechanism 8 can lift and lower the rotating seat 10 to two working positions, so that the two rotating seats 10 are distributed in a straight line or in a V shape. At the same time, the base 5 can adaptively move relatively along the slideway 4 (approach each other, or move away from each other), and the universal ball 6 is an existing component with structures such as a base and a sphere, which is used to reduce the friction in contact with parts and components, thereby facilitating the movement of parts and components.

[0027] Specifically, Figure 3 As shown, the limit adjustment mechanism 8 includes a linear slide rail 87 and a U-shaped frame 82, a square rod 81 is fixedly installed on the lower side of the rotating seat 10, the platform 3 is provided with a through hole for passing the square rod 81, each square rod 81 is provided with two square holes distributed up and down, a linear slide rail 87 is fixedly installed on the upper side of the platform 3, and the slide table of the linear slide rail 87 is fixedly installed with a U-shaped frame 82, both ends of the U-shaped frame 82 are provided with plug blocks 88, and the plug blocks 88 are respectively plugged into the square holes; both ends of the U-shaped frame 82 are located at the front side of the square rod 81, when the U-shaped frame 82 is moved, the U-shaped frame 82 can move forward and backward along the linear slide rail 87, so that the plug blocks 88 are plugged into different square holes to adjust the height of the square rod 81.

[0028] Furthermore, a guide ring 84 is fixedly installed on the upper side of the platform 3, and a guide rod 86 is plugged into the guide ring 84. The rear end of the guide rod 86 is fixedly assembled with the U-shaped frame 82. The guide rod 86 is sleeved with a spring 83, and the spring 83 is against the U-shaped frame 82 and the guide ring 84; the spring 83 enables the U-shaped frame 82 to have a force to move backward, so that the plug block 88 can be stably plugged into the square hole, and the plug block 88 can be separated from the square hole only after the U-shaped frame 82 is pulled forward by the guide rod 86 and the spring 83 is compressed.

[0029] Furthermore, a first handle 85 is fixedly mounted on one end of the guide rod 86 away from the U-shaped frame 82 , and the guide rod 86 can be pulled more conveniently through the first handle 85 , thereby improving the comfort of hand operation.

[0030] Specifically, each set of slideways 4 is two dovetail rails symmetrically arranged front and back, and the base 5 is provided with dovetail grooves matching the dovetail rails. The dovetail rails arranged in this way can improve the stability of the base 5 in translation.

[0031] Furthermore, limit plates 11 are fixedly installed at the left and right ends of the platform 3. The height of the limit plates 11 is greater than the height of the slide 4. The limit plates 11 play a safety protection role to prevent the base 5 from detaching from the platform 3 in an accident and causing harm to the staff.

[0032] In addition, a circumferential positioning structure 9 is provided between the platform 3 and the support seat 1 .

[0033] Specifically, Figure 4 As shown, the circumferential positioning structure 9 includes a polished rod 93 and a screw hole 91. The screw hole 91 is provided on the left side of the bottom of the platform 3, and a through hole is provided on the left side of the top of the support seat 1. The polished rod 93 is inserted into the through hole. A threaded section is provided on the upper end of the polished rod 93, and the threaded section is screwed and assembled with the screw hole 91. When the platform 3 is lifted and moved, the polished rod 93 can be driven to be lifted and lowered along the through hole to avoid circumferential rotation of the platform 3 during the lifting and adjustment, and the polished rod 93 connected by screw connection can be disassembled according to usage requirements.

[0034] Furthermore, a linear bearing 94 is fixedly installed in the through hole, and the light rod 93 is slidably installed in the linear bearing 94. The linear bearing 94 can reduce the resistance of the light rod 93 when it moves up and down.

[0035] Furthermore, a second handle 92 is fixedly mounted on the circumferential side of the polished rod 93 , and the second handle 92 can facilitate the hand to apply a rotational torque on the polished rod 93 , thereby making the installation and disassembly of the polished rod 93 more convenient.

[0036] The working principle of this embodiment:

[0037] Before use, according to the bottom type of the parts to be lifted and assembled, the rotating seat 10 is raised and lowered to the adaptation position through the limit adjustment mechanism 8, so that the two movable plates 7 form a straight or V shape, and the base 5 can slide adaptively to maintain the supporting capacity.

[0038] Then, the light rod 93 is screwed by the second handle 92 to be removed from the platform 3, thereby releasing the circumferential positioning ability of the circumferential positioning structure 9. At this time, the screw in the worm gear lifter 2 can be driven to rotate by the circumferentially rotating platform 3, thereby quickly lifting and lowering the rotating seat 10 to the nearest component assembly height. After completion, the light rod 93 is installed back to restore the circumferential positioning ability of the circumferential positioning structure 9, so that the platform 3 can only be lifted and lowered.

[0039] The parts to be assembled are placed on two rotating seats 10 by hoisting equipment, and the assembly position of the parts is accurately lifted by adjusting the lifting of the worm gear lifter 2. The hoisted parts can also be gradually fed and assembled on the universal ball 6 along the assembly direction, thereby improving the assembly accuracy and efficiency.
