Description

Technical Field

[0001] This utility model relates to the field of control arm accessories technology, specifically a positioning structure for a control arm. Background Technology

[0002] A control arm is a mechanical device typically used to control and regulate the movement of other components or systems. The positioning structure of a control arm usually refers to a mechanical device used to ensure the stability of the control arm at a specific position or angle. Its main function is to provide precise positioning and support.

[0003] In existing technologies, the angle of the control arm is adjusted in multiple directions during operation. When it is adjusted to the required position, there is generally no limiting structure to position it. This causes the control arm to fail to accurately reach the predetermined position during the adjustment process, thus affecting the accuracy of operation. Without limiting, the control arm's ability to adjust to the same position each time may decrease, resulting in poor consistency and repeatability of operation. The control arm may exceed the safe range, causing collisions or damage to surrounding equipment, increasing the safety risks during operation. If the control arm is forcibly adjusted to the limit position without limiting, it may cause overload and damage to the motor or other mechanical parts.

[0004] To address this, a positioning structure for the control arm is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a positioning structure for a control arm to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning structure for a control arm, comprising a support ring, wherein a plurality of guide plates are fixedly connected to the middle of the support ring, and a plurality of mounting seats are fixedly connected to the bottom of the support ring, wherein each guide plate has a guide groove at its bottom, a recessed disc is rotatably connected to the top of one adjacent end of each guide plate, a stepper motor is fixedly connected to the bottom of one adjacent end of each guide plate, the drive end of the stepper motor is fixedly connected to the bottom of the recessed disc, and a plurality of semicircular strips are evenly rotatably connected to the middle of the recessed disc, wherein each semicircular strip is rotatably connected to a slide block at its bottom end away from the recessed disc.

[0007] Preferably, each of the guide plates has a groove in the middle.

[0008] Preferably, the outer wall of the slide block is slidably connected to the inner wall of the slide groove.

[0009] Preferably, the bottom of each slide is fixedly connected to a limit stop.

[0010] Preferably, the top of the limiting baffle is slidably connected to the bottom of the guide plate.

[0011] Preferably, the bottom of each limiting baffle is fixedly connected to a positioning plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By setting an adjustable limit positioning structure in the middle of the mounting base of the control arm, it can be ensured that the control arm can accurately reach the predetermined position during operation, thereby improving working accuracy. Setting limits can prevent the control arm from exceeding the safe range, reduce the risk of collision and accidental damage, and ensure the safety of operators. It can also ensure that the control arm returns to the same position after each operation, improving the consistency and repeatability of operation. By limiting the range of motion of the control arm, wear on mechanical parts can be reduced, the service life of the equipment can be extended, and maintenance costs can be reduced.

[0014] 2. By adjusting the limit structure, operators can make adjustments more easily, reducing concerns about operational accuracy and improving work efficiency. The adjustable limit structure allows for flexible adjustments according to different work requirements, adapting to various operating scenarios, reducing the burden on the control system, and lowering the need for position correction, thereby improving the system's response speed and stability, making maintenance and repair simpler, and allowing operators to make adjustments and inspections quickly.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 An embodiment of this utility model is provided: a positioning structure for a control arm, including a support ring 1, a plurality of guide plates 2 fixedly connected to the middle of the support ring 1, a plurality of mounting seats 3 fixedly connected to the bottom of the support ring 1, a guide groove 4 is provided at the bottom of each guide plate 2, a recessed disc 5 is rotatably connected to the top of one end of the guide plate 2, a stepper motor 8 is fixedly connected to the bottom of one end of the guide plate 2, the driving end of the stepper motor 8 is fixedly connected to the bottom of the recessed disc 5, a plurality of semicircular strips 6 are evenly rotatably connected to the middle of the recessed disc 5, and a slide 7 is rotatably connected to the bottom of the end of the semicircular strips 6 away from the recessed disc 5.

[0023] Among them: the four guide plates 2 are symmetrically distributed in a cross shape, and the rotation trajectory of the semicircular strip 6 operates around the center of the support ring 1;

[0024] Even better: The stepper motor 8 drives the notched disc 5 to rotate. As the notched disc 5 rotates, each semicircular bar 6 rotates synchronously, and the slide block 7 connected to the outer end can slide inside the guide plate 2. With the cooperation of each guide groove 4, the slide block 7 drives the subsequent adjustment. The mounting base 3 can install the positioning structure as a whole on the mounting plate of the control arm, which is convenient for subsequent adjustment. The support ring 1 can connect and support each guide plate 2.

[0025] The guide plate 2 is provided with a groove 11 in the middle. The outer wall of the slide block 7 is slidably connected to the inner wall of the groove 11. The bottom of the slide block 7 is fixedly connected to a limit plate 9. The top of the limit plate 9 is slidably connected to the bottom of the guide plate 2. The bottom of the limit plate 9 is fixedly connected to a positioning plate 10.

[0026] Wherein: the cross-sectional trajectory of the slide groove 11 matches that of the slide block 7;

[0027] Even better: As the slide block 7 moves, the positioning adjustment process becomes more stable with the cooperation of the slide groove 11, and the setting of the limit baffle 9 can guide the movement of the positioning plate 10.

[0028] The working principle of the above implementation is as follows:

[0029] The operation steps are as follows:

[0030] First, the stepper motor 8 drives the concave disc 5 to rotate. As the concave disc 5 rotates, each semicircular bar 6 rotates synchronously, and the slide block 7 connected to the outer end can slide inside the guide plate 2. With the cooperation of each guide groove 4, the slide block 7 drives the subsequent adjustment. The mounting base 3 can install the positioning structure as a whole on the mounting plate of the control arm, which facilitates the operation of subsequent adjustment. The support ring 1 can connect and support each guide plate 2. With the movement of the slide block 7, the positioning adjustment process can be made more stable with the cooperation of the slide groove 11. The setting of the limit baffle 9 can guide the movement of the positioning plate 10. The positioning structure with adjustable limit is set in the middle of the mounting base 3 of the control arm, which can ensure that the control arm can accurately reach the predetermined position during operation, thereby improving the working accuracy. Setting the limit can prevent the control arm from exceeding the safe range, reduce the risk of collision and accidental damage, protect the safety of the operator, and ensure that the control arm can return to the same position every time it is operated, thereby improving the consistency and repeatability of the operation.

[0031] By limiting the range of motion of the control arm, wear on mechanical parts can be reduced, the service life of the equipment can be extended, maintenance costs can be lowered, operators can make adjustments more easily, concerns about operational accuracy can be reduced, and work efficiency can be improved. The adjustable limit structure allows for flexible adjustments according to different work requirements, adapts to a variety of operating scenarios, reduces the burden on the control system, reduces the need for position correction, thereby improving the system's response speed and stability, and making maintenance and repair simpler.
