Description

Technical Field

[0001] This utility model belongs to the field of elastic element technology, specifically relating to adjustable elastic positioning components. Background Technology

[0002] An elastic positioning component is a mechanical part that uses the elastic force of an elastic element to achieve precise positioning and flexible displacement. Its core principle is to use the restoring force generated by elastic deformation to press the positioning component into the positioning groove (hole) of the moving part, which not only ensures positioning accuracy, but also allows the moving part to automatically disengage from the positioning point when subjected to force, thereby achieving dynamic adjustment.

[0003] Traditional elastic positioning elements typically have a fixed and non-adjustable positioning stroke. In practical applications such as machining and assembly, different workpieces or assembly requirements often necessitate different positioning depths and ranges. Fixed-stroke positioning elements cannot meet diverse needs. When different positioning strokes are required, it is necessary to replace them with positioning elements of different specifications. This not only increases production costs but also reduces production efficiency, as frequent replacement of positioning elements consumes a significant amount of time and manpower. Furthermore, adjusting the sliding damping of elastic positioning elements is quite difficult.

[0004] Therefore, existing elastic positioning components have difficulties and inconveniences in adjusting the stroke and sliding damping, resulting in poor overall applicability of the device. Utility Model Content

[0005] In order to overcome the problems of difficulty and inconvenience in adjusting the stroke and sliding damping of existing elastic positioning components, which leads to poor overall applicability of the device, an adjustable elastic positioning component is proposed.

[0006] The technical solution of this utility model is as follows: an adjustable elastic positioning component, including a limiting cylinder; it also includes an L-shaped sliding frame and a screw ring. The inner wall of the limiting cylinder has an inner groove, and a fixed plate is fixedly connected to the lower end of the inner wall of the limiting cylinder. A sliding column is slidably arranged in the inner groove, and a positioning sliding column is fixedly connected to the upper end of the sliding column. A spring is provided at the end of the sliding column and the fixed plate that are close to each other. The outer wall of the limiting cylinder has four first limiting grooves and an annular groove. An L-shaped sliding frame is slidably arranged in the first limiting groove. A threaded groove is provided on the outer wall of the L-shaped sliding frame away from the axis of the limiting cylinder. A screw ring is provided on the outer wall of the limiting cylinder to limit rotation. The inner wall of the screw ring and the outer walls of the four threaded grooves are threadedly connected to each other. A fixed ring is fixedly connected to the lower end of the four L-shaped sliding frames. The arc-shaped inner wall of the fixed ring fits against the arc-shaped outer wall of the annular groove on the limiting cylinder. A damping control component is also provided on the fixed plate.

[0007] Preferably, the damping control assembly includes a limiting sleeve, a sliding rod, and an air-collecting soft shell; the upper end of the fixed plate is connected to the limiting sleeve, and the lower end of the fixed plate is connected to the air-collecting soft shell, with the air-collecting soft shell and the limiting sleeve being interconnected.

[0008] Preferably, the lower end of the gas collecting shell is connected to a threaded pipe, and a threaded sealing cap is installed on the outer wall of the threaded pipe.

[0009] Preferably, a sliding rod is fixedly connected to the lower end of the sliding column, and the sliding rod is slidably disposed within the limiting sleeve.

[0010] Preferably, the outer wall of the limiting cylinder is fixed with two sets of limiting components. The limiting components include a first fixing plate, a second fixing plate, a stud, and a nut. The outer wall of the limiting cylinder is fixed with two second fixing plates and two first fixing plates. The upper end of the second fixing plate is in contact with the lower end of the screw ring, and the lower end of the first fixing plate is in contact with the upper end of the screw ring.

[0011] Preferably, the upper end of the second fixing plate is fixed with two studs, and the studs are threaded with nuts after passing through the upper end of the first fixing plate.

[0012] Preferably, the upper turning surface of the L-shaped sliding frame and the upper turning surface of the sliding column are in contact with each other.

[0013] The beneficial effects of this utility model are as follows: By rotating the upper limit ring of the limiting cylinder, the L-shaped sliding frame of the limiting cylinder is moved up and down, thereby adjusting the sliding stroke of the positioning slide column. The positioning stroke of the positioning slide column can be quickly adjusted without replacing the positioning component.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-5 This utility model provides an embodiment of an adjustable elastic positioning component, including a limiting cylinder 1; it also includes an L-shaped sliding frame 4 and a threaded ring 204. The inner wall of the limiting cylinder 1 has an inner groove 103. A fixed plate 303 is fixedly connected to the lower end of the inner wall of the limiting cylinder 1. A sliding column 301 is slidably arranged in the inner groove 103. A positioning sliding column 3 is fixedly connected to the upper end of the sliding column 301. A spring 302 is provided at one end of the sliding column 301 and the fixed plate 303 that are close to each other. The outer wall of the limiting cylinder 1 has four first limiting grooves 102. An annular groove 101 is also provided on the outer wall of the limiting cylinder 1. An L-shaped sliding frame 4 is slidably arranged in the first limiting grooves 102. A threaded groove 401 is provided on the outer wall of the end of the L-shaped sliding frame 4 away from the axis of the limiting cylinder 1. The outer wall of the device is equipped with a screw ring 204 for limiting rotation. The inner wall of the screw ring 204 and the outer wall of the four threaded grooves 401 are threaded together. The lower ends of the four L-shaped sliding frames 4 are fixedly connected to a fixing ring 402. The arc-shaped inner wall of the fixing ring 402 fits against the arc-shaped outer wall of the annular groove 101 on the limiting cylinder 1. The fixing plate 303 is also equipped with a damping control component. By rotating the screw ring 204 that limits the movement of the limiting cylinder 1, the limiting L-shaped sliding frame 4 is moved up and down, thereby adjusting the sliding stroke of the positioning slide column 3. The positioning stroke of the positioning slide column 3 can be quickly adjusted without replacing the positioning component. The work of adjusting the sliding damping of the positioning slide column 3 through the damping control component improves the overall adaptability and practicality of the device.

[0022] Please see Figures 1-4In this embodiment, two sets of limiting components are fixed to the outer wall of the limiting cylinder 1. The limiting components include a first fixing plate 2, a second fixing plate 201, studs 202 and nuts 203. Two second fixing plates 201 and two first fixing plates 2 are fixed to the outer wall of the limiting cylinder 1. The upper end of the second fixing plate 201 is in contact with the lower end of the screw ring 204, and the lower end of the first fixing plate 2 is in contact with the upper end of the screw ring 204. Two studs 202 are fixed to the upper end of the second fixing plate 201. The studs 202 pass through the upper end of the first fixing plate 2 and are threaded with nuts 203. The upper turning surface of the L-shaped sliding frame 4 and the upper turning surface of the sliding column 301 are in contact with each other. The turning surface on the L-shaped sliding frame 4 slides under the limitation of the first limiting groove 102, thereby shortening the position of the upper end of the inner groove 103, thereby performing the function of distance limiting.

[0023] Please see Figure 2 and Figure 5 In this embodiment, the damping control assembly includes a limiting sleeve 304, a sliding rod 306, and an air-collecting soft shell 305. The upper end of the fixed disk 303 is connected to the limiting sleeve 304, and the lower end of the fixed disk 303 is connected to the air-collecting soft shell 305. The air-collecting soft shell 305 and the limiting sleeve 304 are interconnected. The lower end of the air-collecting soft shell 305 is connected to a threaded pipe 307, and a threaded sealing cap 308 is threadedly installed on the outer wall of the threaded pipe 307. The lower end of the sliding column 301 is fixedly connected to the sliding rod 306, and the sliding rod 306 is slidably disposed on the limiting sleeve. Inside 304, when it is necessary to adjust the sliding damping of the sliding column 301, rotate the threaded sealing cover 308 to prevent the threaded tube 307 from being blocked, press the sliding column 301, and the sliding column 301 drives the sliding rod 306 to move in the limiting sleeve 304, changing the amount of gas in the gas collecting soft shell 305, thereby changing the force of the gas collecting soft shell 305 on the fixed plate 303 and the spring 302, and thus adjusting the damping of the sliding column 301 when sliding. After reaching the appropriate position, fix the amount of gas in the gas collecting soft shell 305 on the threaded sealing cover 308 to keep the sliding damping in the required state.

[0024] When the required elastic positioning component needs adjustment, the screw ring 204 on the outer wall of the limiting cylinder 1 is rotated. The screw ring 204 is limited by the first fixing plate 2 and the second fixing plate 201 through the stud 202, so that the screw ring 204 can rotate but cannot move up and down. Thus, by rotating the screw ring 204, the L-shaped sliding frame 4 moves downward through the threaded groove 401, thereby shortening the sliding stroke of the sliding column 301 in the inner groove 103, thus limiting the sliding position range of the positioning column 3. When it is necessary to adjust the sliding damping of the positioning column 3, the threaded sealing cover 308 is rotated to prevent the threaded tube 307 from being blocked. Then, by pressing the positioning column 3, the positioning column 3 drives the sliding rod 306 to move in the limiting sleeve 304. After reaching the appropriate position, the threaded sealing cover 308 is closed, thereby realizing the adjustment of the resistance of the positioning column 3. By setting adjustable resistance and adjustable sliding stroke, the practicality and adaptability of the device in elastic positioning work are improved.
