Description

Technical Field

[0001] The utility model relates to the technical field of worm and worm gear detection, and particularly relates to an adjustable worm and worm gear connection assembly. Background Art

[0002] As an important transmission mechanism, the worm and worm gear are widely used in the field of general machinery. Its accuracy directly affects the performance of the entire equipment. If there are dimensional deviations, tooth profile errors or improper installation of the worm and worm gear, it will lead to inaccurate transmission ratio, affect the working accuracy of the equipment. Detecting the worm and worm gear is to ensure its manufacturing and installation accuracy.

[0003] Currently, during the detection process of the worm and worm gear, the positions of the worm wheel and the worm are usually relatively fixed. Once installed, it is very difficult to adjust their meshing state. If the backlash between the worm and the worm gear is not properly adjusted during the detection process, two adverse situations will occur: one is that the backlash is too tight, which will increase additional friction and heat generation, accelerating the wear of the components; the other is that the backlash is too loose, which may lead to unstable transmission, causing noise and vibration problems. These two situations will seriously affect the performance and service life of the worm and worm gear transmission system. Therefore, this application provides an adjustable worm and worm gear connection assembly to meet the requirements. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide an adjustable worm and worm gear connection assembly to solve the problems caused by improper adjustment of the backlash between the worm and the worm gear during the detection process.

[0005] To solve the above technical problems, the utility model provides the following technical solutions:

[0006] An adjustable worm and worm gear connection assembly, comprising: a workbench; a driver slidably arranged on the workbench; a clamping block slidably arranged on the workbench, and the driver and the clamping block are symmetrically arranged along the longitudinal center of the workbench; a worm body arranged between the driver and the clamping block; an adjusting part arranged on the workbench and located at the center of the workbench.

[0007] The adjusting part includes: two worm wheel bodies respectively arranged above the workbench, and the worm wheel body meshes with the worm body; a support plate arranged on the workbench; an electric slide rail arranged on the support plate.

[0008] It further includes: a rotating part arranged on the support plate; a mounting plate arranged on the top of the rotating part.

[0009] The rotating part includes: a mounting cylinder arranged on the top of the support plate and connected to the electric slide rail; a driving motor arranged in the mounting cylinder.

[0010] It further includes a rotating plate, which is rotatably arranged on the top of the mounting cylinder, and the top of the rotating plate is connected to the mounting plate.

[0011] The output end of the driving motor is connected to the rotating plate.

[0012] It further includes two threaded rods arranged on the mounting plate; two placing rods are respectively threadedly arranged on the threaded rods; the worm wheel body is sleeved on the placing rod.

[0013] The two threaded rods are symmetrically arranged, and the placing rod is in an inverted T shape.

[0014] It further includes a bidirectional motor arranged at the center of the workbench; two lead screws are respectively arranged on the two output ends of the bidirectional motor; one ends of two sliders are respectively threadedly arranged on the two lead screws, and the other ends are respectively connected to the driver and the clamping block.

[0015] The threads on the surfaces of the two lead screws have opposite helix directions.

[0016] Compared with the prior art, the utility model has at least the following beneficial effects:

[0017] In the above solution, through the electric slide rail and the threaded rod, when the side clearance is too tight, the electric slide rail drives the worm wheel body to move horizontally away from the worm, so as to increase the center distance between the worm wheel and the worm, thereby relieving the situation of too tight side clearance. At the same time, rotating the threaded rod makes the placing rod drive the worm wheel body to move upward, further increasing the distance between the worm wheel and the worm in the vertical direction, so as to comprehensively adjust the side clearance to a proper state, which can reduce the additional friction and heat generated due to too tight side clearance and reduce the wear of components; when the side clearance is too loose, the electric slide rail drives the worm wheel body to move horizontally close to the worm, reducing the center distance between the worm wheel and the worm, making the side clearance smaller, and rotating the threaded rod makes the placing rod drive the worm wheel body to move downward, reducing the distance between the worm wheel and the worm in the vertical direction, so as to achieve the purpose of adjusting the side clearance to a proper state, which can make the transmission more stable and reduce noise and vibration.

[0018] By setting the rotating part, the worm wheel body can be quickly replaced after the detection is completed, reducing the time required to replace the worm wheel body, and at the same time reducing the downtime of the equipment, so that more detection tasks can be completed in the same time, thereby reducing the cost per unit time.

Detailed Embodiments

[0028] The following will describe in detail an adjustable worm and worm wheel connection assembly provided by the present invention with reference to the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some well-known technologies, those skilled in the art can also adopt other alternative methods for implementation; moreover, the accompanying drawings are only for more specifically describing the embodiments and are not intended to specifically limit the present invention.

[0029] As Figure 1 - Figure 6 shown, an embodiment of the present invention provides an adjustable worm and worm wheel connection assembly, including: a workbench 1; a driver 11 slidably disposed on the workbench 1; a clamping block 12 slidably disposed on the workbench 1, and the driver 11 and the clamping block 12 are symmetrically arranged along the longitudinal center of the workbench 1; a worm body 3 disposed between the driver 11 and the clamping block 12; an adjusting part 2 disposed on the workbench 1 and located at the center of the workbench 1.

[0030] By setting the driver 11, a motor and a rotating rod are arranged on the driver 11, and a rotating rod is arranged on the clamping block 12. The worm body 3 is clamped by the rotating rod, and then the rotating rod is driven by the motor to rotate, so that the worm body 3 rotates, enabling it to perform rotational motion during the detection process to better observe the meshing state of the worm and worm gear.

[0031] The adjusting part 2 includes: two worm gear bodies 4, which are respectively arranged above the workbench 1, and the worm gear body 4 meshes with the worm body 3; a support plate 7, which is arranged on the workbench 1; an electric slide rail 8, which is arranged on the support plate 7.

[0032] By setting the electric slide rail 8, precise displacement in the horizontal direction is provided. The electric slide rail 8 drives the rotating part 6 to move precisely in the horizontal direction, enabling the worm gear body 4 installed on the rotating part 6 to adjust its relative position with respect to the worm body 3 in the horizontal direction.

[0033] It also includes: a rotating part 6, which is arranged on the support plate 7; a mounting plate 5, which is arranged on the top of the rotating part 6.

[0034] By setting the mounting plate 5, a mounting plane and a support structure are provided for components such as the threaded rod 10, the placing rod 9, and the worm gear body 4, ensuring that these components can be stably fixed in specific positions for the detection and adjustment operations of the worm and worm gear.

[0035] The rotating part 6 includes: a mounting cylinder 61, which is arranged on the top of the support plate 7 and is connected to the electric slide rail 8; a driving motor 62, which is arranged inside the mounting cylinder 61. By setting the mounting cylinder 61, which is arranged on the top of the support plate 7, a mounting space and stable support are provided for the driving motor 62, ensuring that the driving motor 62 does not shake or displace during operation and guaranteeing its normal operation.

[0036] It also includes: a rotating plate 63, which is rotatably arranged on the top of the mounting cylinder 61, and the top of the rotating plate 63 is connected to the mounting plate 5. By setting the rotating plate 63, which is rotatably arranged on the top of the mounting cylinder 61 and its top is connected to the mounting plate 5, the output end of the driving motor 62 is connected to the rotating plate 63. By the rotation of the driving motor 62, the rotating plate 63 is driven to rotate, and then the mounting plate 5 and the components such as the worm gear installed on it are driven to adjust the angle.

[0037] The output end of the driving motor 62 is connected to the rotating plate 63. By setting the driving motor 62, the output end of the driving motor 62 is fixed to the rotating plate 63. When the driving motor 62 operates through an external current, the output end of the driving motor 62 generates rotational power, driving the rotating plate 63 to perform synchronous motion and providing a power source for the rotation of the rotating plate 63.

[0038] It further includes: two threaded rods 10, which are arranged on the mounting plate 5; two placing rods 9, which are respectively arranged on the threaded rods 10 in a threaded manner; the worm wheel body 4 is sleeved on the placing rod 9. By arranging the threaded rods 10, the vertical position of the worm wheel body 4 can be adjusted, so that the contact point and meshing clearance between the worm wheel body 4 and the worm shaft body 3 can be changed, thereby optimizing the meshing state of the worm and worm wheel and ensuring the smoothness and efficiency of transmission.

[0039] The two threaded rods 10 are symmetrically arranged, and the placing rod 9 is in an inverted T shape. By arranging the placing rod 9, a mounting support structure is provided for the worm wheel body 4. The inverted T shape design can increase the contact area between the placing rod 9 and the mounting plate 5, improve the stability of the placing rod 9. During the detection process of the worm and worm wheel, the placing rod 9 needs to bear the weight of the worm wheel body 4 and various possible forces. The inverted T shape design can better disperse these forces and ensure that the placing rod 9 will not tilt or shake.

[0040] It further includes: a bidirectional motor 15, which is arranged at the center of the workbench 1; two lead screws 13, which are respectively arranged on the two output ends of the bidirectional motor 15; two sliders 14, one end of which is respectively arranged on the two lead screws 13 in a threaded manner, and the other end is respectively connected to the driver 11 and the clamping block 12.

[0041] By setting the bidirectional motor 15 to operate, driving the two lead screws 13 to rotate, so that the two sliders 14 move in opposite directions, thereby enabling the driver 11 and the clamping block 12 to move in opposite directions, completing the clamping and fixing or replacement of the worm shaft body 3.

[0042] The thread directions on the surfaces of the two lead screws 13 are opposite. The purpose of this design is to enable the sliders 14 connected to the two lead screws 13 to achieve synchronous reverse movement under the drive of the bidirectional motor 15, so as to ensure that the driver 11 and the clamping block 12 can move towards the center or both sides simultaneously to accurately clamp or loosen the worm shaft body 3.

[0043] For the technical solution provided by the present utility model, the worm body 3 is placed between the driver 11 and the clamping block 12. The external controller is used to start the operation of the bidirectional motor 15, driving the lead screw 13 to rotate, so that the two sliders 14 move in opposite directions simultaneously to fix the worm body 3. The worm wheel body 4 is placed on the placement rod 9. The external controller is used to start the operation of the electric slide rail 8 to move the worm body 3 forward, so that the worm wheel body 4 contacts the worm body 3. The driver 11 drives the worm body 3 to rotate; the threaded rod 10 is rotated to drive the placement rod 9 to move, adjusting the vertical position of the worm wheel body 4 to make the meshing between the worm wheel body 4 and the worm body 3 more precise; when the backlash is too tight, the electric slide rail 8 drives the worm wheel body 4 to move horizontally away from the worm body 3, thereby increasing the center distance between the worm wheel body 4 and the worm body 3. At the same time, the threaded rod 10 is rotated to drive the placement rod 9 to drive the worm wheel body 4 to move upward, further increasing the distance between the worm wheel body 4 and the worm body 3 in the vertical direction, so as to comprehensively adjust the backlash to a suitable state; when the backlash is too loose, the electric slide rail 8 drives the worm wheel body 4 to move horizontally closer to the worm body 3, reducing the center distance between the worm wheel body 4 and the worm body 3 to make the backlash smaller, and the threaded rod 10 is rotated to drive the placement rod 9 to drive the worm wheel body 4 to move downward, reducing the distance between the worm wheel body 4 and the worm body 3 in the vertical direction, so as to adjust the backlash to a suitable state; after the detection is completed, the electric slide rail 8 moves to drive the worm wheel body 4 to disengage from the worm body 3. The external controller is used to start the operation of the driving motor 62 to drive the rotating plate 63 to rotate, rotating the detected worm wheel body 4 so that a new worm wheel body 4 can be detected.
