[0001] This utility model relates to the field of clamping technology, and in particular to a clamping device for synchronous polishing of multiple curved door handles. Background Technology
[0002] Door handles come in a variety of shapes and styles, with curved tube handles being particularly popular due to their simple and elegant design. To achieve a smoother surface, workers use polishing equipment during the manufacturing process. Existing roller polishing devices can polish multiple curved tube handles simultaneously using polishing rollers. However, to polish multiple curved tube handles at the same time, workers need to use clamps to hold them in place, ensuring they are all simultaneously entered into the polishing roller for polishing.
[0003] Existing polishing fixtures are usually vise-type fixtures. Although these fixtures can hold multiple bent pipe handles, they are cumbersome to operate, bulky, and not flexible enough to adjust, resulting in low work efficiency. Utility Model Content

[0025] The present invention will be described in detail below with reference to specific embodiments.
[0026] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through one or more intermediate media. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The directional terms appearing in this utility model are for the purpose of better describing the characteristics of the features and the relationships between them. It should be understood that when the placement direction of this utility model changes, the direction of the characteristics of the features and the relationships between them also changes accordingly. Therefore, directional terms do not constitute an absolute limitation on the characteristics of the features and the relationships between them in space, but only a relative limitation.
[0027] like Figures 1 to 6 As shown, this utility model provides a fixture for synchronous polishing of multiple curved door handles, including a fixture body. The fixture body includes a fixed clamping plate 1, a movable clamping plate 2, and multiple sets of clamping components 3. The clamping components 3 are used to move the movable clamping plate 2 closer to or away from the fixed clamping plate 1. Each clamping component 3 includes a fixed handle 30, an L-shaped curved bridge 31, and a movable handle 32. The fixed clamping plate 1 and the fixed handle 30 are fixedly connected. One end of the curved bridge 31 is fixedly installed on the movable clamping plate 2, and the other end of the curved bridge 31 is hinged to the fixed handle 30. The movable handle 32 is hinged at the L-shaped bend of the curved bridge 31. A connecting post 33 is hinged on the movable handle 32, and the other end of the connecting post 33 can slide on the fixed handle 30. A return spring 36 is also provided on the fixed handle 30, and the other end of the return spring 36 is connected to the curved bridge 31.
[0028] With the above design, when polishing is required, the worker can lift the movable handle 32 to lift the movable clamp 2, separating the movable clamp 2 from the fixed clamp 1. The worker only needs to place the curved door handle on the table or step in sequence so that one section of the curved door handle is suspended in the air, place the fixed clamp 1 at the suspended curved door handle, and then press down on the movable handle 32 to bring the movable clamp 2 closer to the fixed clamp 1, so that the curved door handle is clamped between the movable clamp 2 and the fixed clamp 1.
[0029] In this embodiment, the fixed grip 30 is provided with an adjustment groove 300, the curved bridge 31 is hinged to the end of the adjustment groove 300 near the fixed clamping plate 1, the fixed grip 30 is provided with a sliding groove 301 at the end away from the fixed clamping plate 1, and the connecting column 33 is provided with a sliding rod at the end away from the movable grip 32, and the sliding rod can slide in the sliding groove 301.
[0030] In this embodiment, an adjusting bolt 35 is provided at the end of the fixed handle 30 away from the fixed clamping plate 1. The adjusting bolt 35 is used to adjust the sliding range of the slide rod in the slide groove 301.
[0031] In this embodiment, the curved bridge 31 includes a vertical section 311 and a horizontal section 310 connected to each other. The horizontal section 310 is fixedly connected to the movable clamp 2, and the vertical section 311 is hinged to the fixed handle 30. A hinge hole 312 is provided at the connection between the vertical section 311 and the horizontal section 310. The hinge hole 312 is used to hinge with the movable handle 32.
[0032] In this embodiment, the movable handle 32 is provided with a gripping part 321 and a hinge part 320. The hinge part 320 is used to hinge the curved bridge 31 and the connecting column 33. The gripping part 321 is located at the end away from the hinge part 320. A limit bolt 34 is provided on the gripping part 321 near the hinge part 320. The limit bolt 34 is used to limit the downward pressing distance of the connecting column 33.
[0033] With the above design, when the gripping part 321 is lifted upwards, the curved bridge 31 is forced to tilt the movable clamp 2 backwards, and the movable clamp 2 is opened. When the straight line connecting the hinge hole 312 and the hinge position at the front end of the connecting column 33 coincides with the axis of the connecting column 33, the clamp is in an intermediate state. At this time, the return spring 36 is stretched to its maximum value, and the distance between the movable clamp 2 and the fixed clamp 1 is the smallest. The operator can adjust the sliding range of the slide rod by turning the adjusting bolt 35. The more the adjusting bolt 35 is turned in, the more the curved bridge 31 rotates counterclockwise (in...). Figure 4In the structure shown), the smaller the distance between the movable clamping plate 2 and the fixed clamping plate 1, the more adaptable it is to curved door handles of different sizes. When the straight line connecting the hinge hole 312 and the hinge position at the front end of the connecting post 33 forms an angle other than 180° with the straight line of the connecting post 33, let this angle be angle A, which is less than 180°. If angle A is in the direction towards the fixed handle 30 (e.g., Figure 5 As shown), the clamp is in a relaxed state. If angle A is 30 degrees away from the fixed grip (as shown), Figure 4 As shown), the clamp is in a self-locking state; whether in the tensioned or self-locking state, the smaller the angle A, the greater the distance between the movable clamp 2 and the fixed clamp 1.
[0034] The clamp can switch between a relaxed state, an intermediate state, and a self-locking state. When the user pulls the movable handle 32 upward to put the clamp into the relaxed state, the curved bridge 31 automatically tilts backward under the action of the return spring 36, causing the movable clamping plate 2 and the fixed clamping plate 1 to open. When it is necessary to clamp the curved pipe door handle, the operator only needs to place the clamp in the relaxed state at the suspended curved pipe door handle and press the movable handle 32 to gradually switch the clamp from the relaxed state to the intermediate state. When the user continues to press, the clamp begins to switch from the intermediate state to the self-locking state. Under the restriction of the upper limit bolt 34 of the movable handle 32, the function of the upper limit bolt 34 is to press against the connecting column 33 after the clamp just switches to the self-locking state, so that the angle between the movable handle 32 and the connecting column 33 cannot continue to decrease, so that the clamp in the self-locking state will not open freely like the clamp in the relaxed state, thus preventing the clamped curved pipe door handle from being released. In the self-locking state, the function of the return spring 36 is to make the angle A tend to decrease rather than tend to become 180°. At the same time, in conjunction with the limiting function of the limiting bolt 34, the clamp is kept in the self-locking state, that is, the angle A remains unchanged, and the clamp can only be opened by the operator lifting the gripping part 321.
[0035] Because the spring force of the return spring 36 is greatest in the intermediate state and the distance between the movable clamp 2 and the fixed clamp 1 is smallest, when it is necessary to clamp the curved pipe door handle, the user needs to press hard to make the movable handle 32 move from the relaxed state to the intermediate state and enter the self-locking state; when it is necessary to remove the polished curved pipe door handle from the clamp, the user needs to lift the movable handle 32 to make the clamp move from the self-locking state to the intermediate state and enter the relaxed state; since the force required to move over the intermediate state is relatively large, it can effectively prevent the curved pipe door handle from slipping during polishing work and avoid affecting the processing effect.
[0036] In this embodiment, both the fixed clamping plate 1 and the movable clamping plate 2 are provided with anti-slip pads 4. The anti-slip pads 4 can increase the friction between the clamping body and the curved pipe door handle, preventing the curved pipe door handle from sliding during the polishing process. At the same time, the soft rubber material of the anti-slip pads 4 can also protect the curved pipe door handle and prevent the clamped part from being scratched.
[0037] In this embodiment, baffles 10 are provided at both ends of the fixed clamping plate 1, and locking posts 11 are provided on the baffles 10. The locking posts 11 on the baffles 10 can also lock the main body of the clamp onto the polishing equipment to prevent the bent tube from sliding during polishing.
[0038] The present invention provides a clamp for simultaneously polishing multiple curved door handles. Compared with the prior art, the user can adjust the distance between the movable clamping plate 2 and the fixed clamping plate 1 by using the movable handle 32. The movable clamping plate 2 and the fixed clamping plate 1 are relatively wide, which can clamp multiple curved door handles at the same time. The user only needs to pull the movable handle 32 to move the movable clamping plate 2 and the fixed clamping plate 1 closer or further apart, so that multiple curved door handles can be clamped or released simultaneously. The clamp is simple to operate and compact and lightweight, which effectively improves polishing efficiency.
[0039] Where there is no conflict, the above embodiments and features can be combined with each other.
[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
