Description

Technical Field

[0001] This utility model relates to the field of positioning mechanism technology, specifically to a resonant column processing positioning mechanism. Background Art

[0002] A resonant column is an important engineering tool that can effectively control and manage vibration problems. The resonant column machining and positioning mechanism is a device used to ensure that the various parts of the resonant column remain accurately positioned.

[0003] The existing resonant column processing and positioning mechanism is as follows: a first clamping member and a second clamping member are set on the fixture, and clamping grooves are set on the first clamping member and the second clamping member. The resonant column is placed between the clamping grooves, and the first clamping member and the second clamping member are moved at the same time to clamp and position the resonant column.

[0004] While this method can achieve the clamping and positioning of the resonant column, the following problems still exist: Since the shape of the clamping groove is difficult to adjust, a single positioning mechanism can often only process resonant columns of one size. If the specifications of the processed resonant column change, a new clamping and positioning mechanism needs to be replaced, resulting in a limited range of applications. Utility Model Content

[0005] This utility model proposes a resonant column processing and positioning mechanism, which solves the problem that the resonant column processed by the existing resonant column processing and positioning mechanism has a limited applicable range, and improves the practicality of the equipment.

[0006] A resonant column processing and positioning mechanism includes a mounting base.

[0007] A first clamping member is slidably connected to the mounting base. A second clamping member and a third clamping member are respectively provided on both sides of the first clamping member. The second and third clamping members are rotatably connected to the mounting base. The mounting base is provided with a connection structure for controlling the second and third clamping members to simultaneously clamp and move closer to the resonant column when the first clamping member moves closer to it, and for controlling the second and third clamping members to simultaneously move away from the resonant column when the first clamping member moves away from it. The mounting base is also provided with an adjustment structure for adjusting the position of the first, second, and third clamping members when clamping the resonant column.

[0008] Furthermore, the connecting structure includes a first connecting wheel and a second connecting wheel. The first clamping member has a first sliding slope and a second sliding slope on both sides. The first connecting wheel is rotatably connected to the second clamping member, and the second connecting wheel is rotatably connected to the third clamping member. The first connecting wheel abuts against the first sliding slope, and the second connecting wheel abuts against the second sliding slope.

[0009] Furthermore, the end of the second clamping member away from the first connecting wheel is rotatably connected to a second clamping wheel, the end of the third clamping member away from the second connecting wheel is rotatably connected to a third clamping wheel, and the end of the first clamping member near the second clamping wheel is rotatably connected to a first clamping wheel.

[0010] Furthermore, a first limiting spring is provided between the second clamping member and the third clamping member, and the two ends of the first limiting spring are fixedly connected to the second clamping member and the third clamping member, respectively.

[0011] Furthermore, the adjustment structure includes an adjustment bolt, a limiting plate is fixed to the end of the first clamping member away from the second clamping member, the mounting base is provided with a first sliding groove and a second sliding groove, the mounting base is provided with a limiting member, the limiting member is slidably connected to both the first sliding groove and the second sliding groove, the limiting member abuts against the limiting plate, a first mounting plate and a second mounting plate are fixed to the side of the mounting base away from the first clamping member, an adjustment screw is rotatably connected between the first mounting plate and the second mounting plate, the limiting member is threadedly connected to the adjustment screw, and the adjustment bolt is fixedly disposed at the end of the adjustment screw.

[0012] Furthermore, the first clamping member is provided with a third sliding groove on the side near the limiting plate. Both sides of the side wall of the third sliding groove are provided with sliding holes. A sliding rod is slidably connected in the sliding holes. A limiting bolt is fixed on the sliding rod. A second limiting spring is also sleeved on the sliding rod. One end of the second limiting spring is fixedly connected to the third sliding groove away from the end of the limiting plate, and the other end of the second limiting spring is fixedly connected to the limiting bolt.

[0013] Furthermore, the mounting base is also provided with a telescopic component, the fixed end of which is fixedly connected to the mounting base, and the telescopic end of which is fixedly connected to the sliding rod.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] The working process of this embodiment is as follows: When it is necessary to change the specifications of the resonant column to be processed, the resonant column to be processed is first placed between the first clamping member, the second clamping member, and the third clamping member. Then, the telescopic member is activated so that the first clamping member, the second clamping member, and the third clamping member are close to the resonant column. Then, the adjusting bolt is rotated so that the limiting member abuts against the limiting plate, thus completing the change of the clamping specifications of the resonant column. To process the next resonant column, it is only necessary to activate the extension and retraction of the telescopic member to achieve the clamping and fixing of the resonant column.

[0016] In this embodiment, a first clamping member is slidably mounted on the mounting base, and a second and third clamping members are rotated. The resonant column is clamped and released through a connecting structure, and the specifications of the clamped and positioned resonant column are adjusted by an adjustment structure. This design replaces the existing technology that directly uses the first and second clamping members to clamp and fix the resonant column. This utility model expands the applicable range of processing resonant columns and has strong practicality. Attached Figure Description

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] like Figures 2-5As shown, this embodiment proposes a resonant column processing and positioning mechanism, the structure of which includes a mounting base 1. In this embodiment, a first clamping member 2 is slidably disposed on the mounting base 1, and a second clamping member 3 and a third clamping member 4 are respectively disposed on both sides of the first clamping member 2. Both the second clamping member 3 and the third clamping member 4 are rotatably connected to the mounting base 1. The connecting structure is disposed on the mounting base 1 to control the second clamping member 3 and the third clamping member 4 to simultaneously clamp and move closer to the resonant column when the first clamping member 2 approaches it, and to control the second clamping member 3 and the third clamping member 4 to simultaneously move away from the resonant column when the first clamping member 2 moves away from it. An adjustment structure is disposed on the mounting base 1 to adjust the position of the first clamping member 2, the second clamping member 3, and the third clamping member 4 when clamping the resonant column. The mounting base 1 of this embodiment can be mounted on a robotic arm to perform multi-angle processing such as rotation and movement of the resonant column. In this embodiment, the resonant column is clamped and positioned simultaneously by the first clamping member 2, the second clamping member 3, and the third clamping member 4. This allows for the clamping and positioning of resonant columns of different specifications simply by adjusting the distance between the first clamping member 2, the second clamping member 3, and the third clamping member 4. Since the first clamping member 2, the second clamping member 3, and the third clamping member 4 simultaneously approach the resonant column to clamp and fix it, even if the specifications of the processed resonant column change, the center position of the resonant column does not deviate. This reduces the need to adjust the position of the mounting base 1, resulting in more precise processing.

[0027] The adjustment structure in this embodiment includes an adjusting bolt 94, a limiting plate 24 fixedly disposed at the end of the first clamping member 2 away from the second clamping member 3, a first sliding groove 11 and a second sliding groove 12 disposed on the mounting base 1, a limiting member 6 disposed on the mounting base 1, and the limiting member 6 simultaneously slidingly connected to the first sliding groove 11 and the second sliding groove 12, and abutting against the limiting plate 24; a first mounting plate 91 and a second mounting plate 92 fixedly disposed on the side of the mounting base 1 away from the first clamping member 2; an adjusting screw 93 rotatably disposed between the first mounting plate 91 and the second mounting plate 92; the limiting member 6 threadedly connected to the adjusting screw 93; and an adjusting bolt 94 fixedly disposed at the end of the adjusting screw 93. In this embodiment, the movement of the limiting member 6 is controlled by rotating the adjusting screw 93, so that when the adjusting screw 93 is not rotated, the position of the limiting member 6 can be self-locked and will not move. This ensures that during large-scale production, the clamping of the workpiece will not become too tight or too loose due to the increase in the number of processing operations.

[0028] In this embodiment, the third sliding groove 25 is located on the side of the first clamping member 2 near the limiting plate 24. Sliding holes 251 are located on both sides of the sidewall of the third sliding groove 25. The sliding rod 8 is slidably disposed within the sliding hole 251. The limiting bolt 82 is fixedly disposed on the sliding rod 8. The second limiting spring 81 is sleeved on the sliding rod 8. One end of the second limiting spring 81 is fixedly connected to the third sliding groove 25 away from the limiting plate 24, and the other end of the second limiting spring 81 is fixedly connected to the limiting bolt 82. This embodiment uses a second limiting spring 81 added inside the first clamping member 2. The second limiting spring 81 pushes the second clamping member 3 and the third clamping member 4 to clamp the workpiece, ensuring that when the limiting member 6 abuts against the limiting plate 24, the movement of the first clamping member 2 has a certain buffer, preventing collision damage to the equipment.

[0029] In this embodiment, the mounting base 1 is also provided with a telescopic component 7. The fixed end of the telescopic component 7 is fixedly connected to the mounting base 1, and the telescopic end of the telescopic component 7 is fixedly connected to the sliding rod 8. The telescopic component 7 used in this embodiment is preferably a hydraulic cylinder or a pneumatic cylinder. Hydraulic cylinders or pneumatic cylinders are existing technologies and will not be described in detail in this embodiment. Since the pneumatic or hydraulic cylinder is driven by fluid, the resulting thrust has a certain buffering effect, reducing the clamping wear of the first clamping component 2, the second clamping component 3, and the third clamping component 4 on the workpiece.

[0030] The connection structure in this embodiment includes a first connecting wheel 32 and a second connecting wheel 42. A first sliding ramp 22 and a second sliding ramp 23 are disposed on both sides of the first clamping member 2. The first connecting wheel 32 is rotatably connected to the second clamping member 3, and the second connecting wheel 42 is rotatably connected to the third clamping member 4. The first connecting wheel 32 abuts against the first sliding ramp 22, and the second connecting wheel 42 abuts against the second sliding ramp 23. Under the action of the first sliding ramp 22 and the second sliding ramp 23, the distance between the first connecting wheel 32 and the second connecting wheel 42 and the central axis of the first clamping member 2 changes, so that when the first clamping member 2 moves, it can simultaneously drive the second clamping member 3 and the third clamping member 4 to rotate. In this embodiment, the first connecting wheel 32 and the second connecting wheel 42 contact the first sliding ramp 22 and the second sliding ramp 23, reducing the sliding wear of the first clamping member 2 and the second clamping member 3 relative to the first sliding ramp 22 and the second sliding ramp 23, and extending the service life of the equipment.

[0031] In this embodiment, the second clamping wheel 31 is rotatably disposed at the end of the second clamping member 3 away from the first connecting wheel 32, the third clamping wheel 41 is rotatably disposed at the end of the third clamping member 4 away from the second connecting wheel 42, and the first clamping wheel 21 is rotatably disposed at the end of the first clamping member 2 near the second clamping wheel 31. This embodiment uses the first clamping wheel 21, the second clamping wheel 31, and the third clamping wheel 41 to clamp and position the resonant column. Due to the rolling friction between the clamping wheels and the resonant column, wear damage to the resonant column during clamping is reduced, resulting in a more robust and durable clamping system.

[0032] In this embodiment, the first limiting spring 5 is disposed between the second clamping member 3 and the third clamping member 4, and both ends of the first limiting spring 5 are fixedly connected to the second clamping member 3 and the third clamping member 4, respectively. This design is used to ensure that the first connecting wheel 32 and the second connecting wheel 42 abut against the first sliding inclined surface 22 and the second sliding inclined surface 23, so that when the first clamping member 2 is moved, the first clamping member 2 and the third clamping member 4 can be driven to clamp the workpiece simultaneously.

[0033] The working process of this embodiment is as follows: When it is necessary to change the specifications of the resonant column to be processed, the resonant column to be processed is first placed between the first clamping member 2, the second clamping member 3 and the third clamping member 4. Then, the telescopic member 7 is activated so that the first clamping member 2, the second clamping member 3 and the third clamping member 4 are close to the resonant column. Then, the adjusting bolt 94 is rotated so that the limiting member 6 abuts against the limiting plate 24, thus completing the change of the clamping specifications of the resonant column. To process the next resonant column, it is only necessary to activate the extension and retraction of the telescopic member 7 to achieve the clamping and fixing of the resonant column.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
