Description

Technical Field

[0001] This application belongs to the field of automated production line technology, and relates to a floating worm gear assembly device and gearbox assembly equipment. Background Technology

[0002] In existing technologies, during gearbox assembly, the worm gear is directly installed into the gearbox manually or using a device combined with a visual guide. Because the teeth on the worm gear are spur or helical and need to mesh with the worm, the worm gear cannot be directly inserted; a certain assembly angle is required. In existing technologies, regardless of whether assembly is done manually or with a visual guide, there is a risk of the worm gear colliding with the worm, resulting in damage to the worm gear teeth due to forced assembly. Utility Model Content

[0003] The purpose of this application is to provide a floating worm gear assembly device and a gearbox assembly equipment, which aims to solve the technical problem of worm gear tooth damage caused by hard assembly of worm gear and worm in the prior art.

[0004] To achieve the above objectives, the technical solution adopted in this application embodiment is as follows: a floating worm gear assembly device is provided, including a clamping assembly for clamping the worm gear, a floating assembly located above the clamping assembly, a rotating assembly connected to the floating assembly and the clamping assembly, and a lifting assembly that drives the rotating assembly to move up and down. The floating assembly includes a first connecting member, a guide rod passing through the first connecting member, and an elastic buffer sleeved on the guide rod. The bottom end of the guide rod passes through the top end of the clamping assembly, and the top end of the clamping assembly abuts against the bottom end of the elastic buffer. When the lifting assembly drives the rotating assembly, the floating assembly, and the clamping assembly to move downward to insert the worm gear into the gearbox, when the worm gear collides with the worm, the top end of the clamping assembly moves upward along the guide rod to compress the elastic buffer. At the same time, the rotating assembly drives the floating assembly and the clamping assembly to rotate at a certain angle.

[0005] Furthermore, the first connecting member includes a first horizontal plate and a connecting sleeve located at the top of the first horizontal plate and communicating with the first horizontal plate. The clamping assembly includes a second horizontal plate, a cylinder fixed to the bottom of the second horizontal plate, and at least two grippers driven by the cylinder. The guide rod passes through the first horizontal plate and the second horizontal plate. The second horizontal plate is connected to the rotating assembly through a connecting member passing through the connecting sleeve.

[0006] Furthermore, there are four guide rods, which are symmetrically arranged in pairs on the first horizontal plate and the second horizontal plate.

[0007] Furthermore, there are four elastic buffers, which are divided into a first group of elastic buffers and a second group of elastic buffers. Both the first group of elastic buffers and the second group of elastic buffers include two elastic buffers arranged diagonally, wherein the length of the first group of elastic buffers is greater than the length of the second group of elastic buffers.

[0008] Furthermore, sleeves are respectively fitted on the two guide rods corresponding to the second set of elastic buffer members. The top of the sleeve extends out from the first horizontal plate, the bottom of the sleeve is located below the first horizontal plate, the top of the second set of elastic buffer members abuts against the bottom end face of the sleeve, and the bottom of the second set of elastic buffer members abuts against the upper surface of the second horizontal plate.

[0009] Furthermore, a gasket is fitted on each of the two guide rods corresponding to the first set of elastic buffer members. The gasket is located below the first horizontal plate, and the top end of the first set of elastic buffer members abuts against the gasket, while the bottom end of the first set of elastic buffer members abuts against the second horizontal plate.

[0010] Furthermore, the top of the guide rod extends above the first horizontal plate, and the upper part of the guide rod has an external thread, through which the guide rod is connected to the rotating assembly.

[0011] Furthermore, it also includes a horizontal movement component, wherein the lifting component is disposed on the horizontal movement component.

[0012] Furthermore, the horizontal movement component includes a forward and backward movement component and a left and right movement component that can drive the forward and backward movement component to move.

[0013] This application also provides a gearbox assembly device having the aforementioned floating worm gear assembly device.

[0014] In this application, when the lifting assembly drives the rotating assembly, floating assembly, and clamping assembly to move downwards to insert the worm gear into the gearbox, the top of the clamping assembly moves upwards along the guide rod to compress the elastic buffer when the worm gear collides with the worm. At the same time, the rotating assembly drives the floating assembly and clamping assembly to rotate at a certain angle. In this way, the worm gear avoids direct collision with the worm. After the floating assembly and clamping assembly rotate at a certain angle, the lifting assembly again drives the rotating assembly, floating assembly, and clamping assembly to move downwards to insert the worm gear, then floats upwards again, and rotates again until the worm gear is successfully inserted, thereby avoiding damage to the worm gear due to tooth collision.

[0026] Reference Figure 1 , Figure 2 This application provides a floating worm gear assembly device, including a clamping assembly 20 for clamping a worm gear 10, a floating assembly 30 located above the clamping assembly 20, a rotating assembly (not shown in the figure) connected to the floating assembly 30 and the clamping assembly 20, and a lifting assembly (not shown in the figure) that drives the rotating assembly to move up and down. In this application, a floating assembly 30 is added between the clamping assembly 20 and the rotating assembly and the lifting assembly, so as to achieve flexible installation of the worm gear 10.

[0027] Specifically, the floating assembly 30 includes a first connector 31, a guide rod 32 passing through the first connector 31, and an elastic buffer 33 sleeved on the guide rod 32. The bottom end of the guide rod 32 passes through the top end of the clamping assembly 20, and the top end of the clamping assembly 20 abuts against the bottom end of the elastic buffer 33. In this embodiment, when the lifting assembly drives the rotating assembly, the floating assembly 30, and the clamping assembly 20 to move downward to insert the worm gear 10 into the gearbox, when the worm gear 10 collides with the worm, the top end of the clamping assembly 20 moves upward along the guide rod 32 to compress the elastic buffer 33. At the same time, the rotating assembly drives the floating assembly 30 and the clamping assembly 20 to rotate at a certain angle. In this way, the worm gear 10 avoids direct collision with the worm. After the floating assembly 30 and the clamping assembly 20 rotate at a certain angle, the lifting assembly again drives the rotating assembly, the floating assembly 30, and the clamping assembly 20 to move downward to insert the worm gear 10, then floats upward again, and then rotates again until the worm gear 10 is successfully inserted.

[0028] In this embodiment, the first connector 31 includes a first horizontal plate 311 and a connecting sleeve 312 located on top of the first horizontal plate 311 and communicating with the first horizontal plate 311.

[0029] The clamping assembly 20 includes a second horizontal plate 21, a cylinder 22 fixed to the bottom of the second horizontal plate 21, and at least two grippers 23 driven by the cylinder 22. In this embodiment, there are three grippers 23. Three grippers 23 provide a more stable gripping experience when holding the worm gear 10. A guide rod 32 passes through the first horizontal plate 311 and the second horizontal plate 21, and the second horizontal plate 21 is connected to the rotating assembly via a connector passing through the connecting sleeve 312.

[0030] Furthermore, when the worm gear 10 contacts the worm, the clamping assembly 20 floats upward along the guide rod 3232. To improve the guiding effect of the clamping assembly 20, in this embodiment, there are four guide rods 3232, which are symmetrically arranged in pairs on the first horizontal plate 311 and the second horizontal plate 21.

[0031] Similarly, there are four elastic buffer elements 33, each a spring, which are respectively sleeved on the four guide rods 3232. The four elastic buffer elements 33 are divided into a first group of elastic buffer elements 331 and a second group of elastic buffer elements 332. Both the first group of elastic buffer elements 331 and the second group of elastic buffer elements 332 include two elastic buffer elements 33 arranged diagonally, wherein the length of the first group of elastic buffer elements 331 is greater than the length of the second group of elastic buffer elements 332. The first group of elastic buffer elements 331 and the second group of elastic buffer elements 332 are made of the same material. When the clamping assembly 20 moves upward to push the elastic buffer elements 33, the two groups of elastic buffer elements have different stiffness coefficients and elasticity coefficients, which can better and more evenly play a buffering role, ensuring the flexible assembly between the worm gear 10 and the worm.

[0032] Furthermore, sleeves 34 are respectively fitted onto the two guide rods 32 corresponding to the second set of elastic buffer members 332. The top of the sleeves 34 extends from the first horizontal plate 311, and the bottom of the sleeves 34 is located below the first horizontal plate 311. The top of the second set of elastic buffer members 332 abuts against the bottom end face of the sleeves 34, and the bottom of the second set of elastic buffer members 332 abuts against the upper surface of the second horizontal plate 21. Gaskets 35 are respectively fitted onto the two guide rods 32 corresponding to the first set of elastic buffer members 331. The gaskets 35 are located below the first horizontal plate 311, and the top of the first set of elastic buffer members 331 abuts against the gaskets 35, while the bottom of the first set of elastic buffer members 331 abuts against the second horizontal plate 21. In this embodiment, since the lengths of the elastic buffer members 33 in the two sets of elastic buffer members are different, different elastic buffer members 33 are adapted and installed using sleeves 34 and gaskets 35 respectively, making the structure simple and easy to install and disassemble.

[0033] In this embodiment, the connection between the floating component 30 and the rotating component is achieved through the guide rod 32. Specifically, the top of the guide rod 32 extends above the first horizontal plate 311, and the upper part of the guide rod 32 has an external thread 321. The guide rod 32 is fixedly connected to the rotating component through the external thread 321.

[0034] Furthermore, the floating worm gear 10 assembly device also includes a horizontal moving component (not shown in the figure), and a lifting component is mounted on the horizontal moving component. The horizontal moving component includes a front-to-back moving component and a left-to-right moving component that can drive the front-to-back moving component to move. In this embodiment, the lifting component, the front-to-back moving component, the left-to-right moving component, and the rotating component form a four-axis manipulator, which can drive the clamping assembly and the worm gear 10 to move up and down, front and back, left and right, and rotate. Before assembly, the worm gear 10 needs to be lubricated. When the rotating component drives it to rotate, it is convenient to apply oil to the circumference of the worm gear 10; the front-to-back moving component and the left-to-right moving component facilitate the horizontal movement of the worm gear 10, while the lifting component is used to assemble the oiled worm gear 10.

[0035] This application also provides a gearbox assembly device (not shown in the figure), which has the aforementioned floating worm gear 10 assembly device. During the assembly of the worm gear 10, the lifting assembly, rotating assembly, and floating assembly 30 work together to cause the worm gear 10 to float upwards, rotate, and then descend for installation, achieving flexible installation of the worm gear 10. This effectively prevents the worm gear 10 from colliding with the teeth and causing damage, improving assembly efficiency and yield.

[0036] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
