Technical Field

[0001] This utility model relates to the field of clamping technology, specifically to an adjustable quick positioning clamp. Background Technology

[0002] A fixture is a tool used to fix a workpiece or process equipment, providing support, positioning, and locking functions to ensure the workpiece remains stable during processing. It is widely used in machining, assembly lines, welding, and assembly processes. Fixture manufacturing involves multiple fields such as mechanical design, metal processing, and manufacturing processes, and can improve production efficiency, reduce labor costs, and minimize human error, thereby lowering production costs.

[0003] Most existing positioning fixtures are designed to hold and fix flat or small surfaces. When holding non-flat surfaces, they are prone to detachment or damage to the workpiece. Furthermore, the clamping components are prone to tilting during movement, which makes it difficult to meet current requirements. Therefore, this application provides an adjustable quick positioning fixture. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model proposes an adjustable quick positioning fixture that can be adjusted in parallel as a whole and adjusted to fit the workpiece contact surface.

[0005] The technical solution of this utility model is implemented as follows:

[0006] Adjustable quick-positioning fixture, comprising fixture body, movable component and adaptive component, characterized in that:

[0007] The fixture body has a clamping area on its outside, a central shaft is movably connected to the outside of the clamping area, a parallel shaft is fixedly connected to the outside of the clamping area, and a guide rail is fixedly connected to the outside of the clamping area.

[0008] The active component and the adaptive component are provided with a primary arc groove on their exteriors. The adaptive component includes a primary fan plate, a secondary fan plate, and a tertiary fan plate.

[0009] Furthermore, a structural compartment is provided on the outside of the fixture body, and the end of the central shaft and the parallel shaft away from the fixture body is located inside the structural compartment. A connecting gear is fixedly connected to the outside of the end of the central shaft and the parallel shaft away from the fixture body. An adjusting handle is movably connected inside the structural compartment, and a transmission gear is fixedly connected to the outside of the adjusting handle.

[0010] Furthermore, the central shaft and the connecting gear at the ends of the parallel shaft are movably connected to a transmission belt, the transmission gear meshes with the connecting gear at the ends of the central shaft, and the adjusting handle is movably connected to the outer wall of the structural compartment.

[0011] Furthermore, a secondary arc groove is formed on the outside of the primary fan plate, and a tertiary arc groove is formed on the outside of the secondary fan plate. There are multiple sets of tertiary arc grooves, which are evenly distributed on the outside of the secondary fan plate.

[0012] Furthermore, the movable component has a guide groove on its exterior and a threaded groove on its exterior. The guide groove is fitted and connected to the guide rail, and the threaded groove is threadedly connected to the central shaft and the parallel shaft. The vertical height of the central shaft and the parallel shaft is lower than that of the guide rail.

[0013] Furthermore, there are multiple sets of primary arc grooves symmetrically distributed outside the fixture body and the movable components, and two sets of secondary arc grooves symmetrically distributed outside the primary fan plate.

[0014] Furthermore, the first-level fan plate is fitted and connected to the first-level arc groove, the second-level fan plate is fitted and connected to the second-level arc groove, and the third-level fan plate is fitted and connected to the third-level arc groove.

[0015] Furthermore, there are two sets of parallel axes symmetrically distributed outside the clamping area, and two sets of guide rails symmetrically distributed between the central axis and the parallel axes. The workpiece is movably connected between the fixture body and the movable component.

[0016] This utility model has the following beneficial effects:

[0017] 1. By setting the central axis, parallel axis, guide rail, and adjusting the handle, the device can maintain parallel movement during operation, preventing the contact surface from tilting and ensuring the device's clamping stability.

[0026] The technical solutions in the embodiments of this utility model will be clearly and completely described below. 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 skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Example 1

[0028] Please see Figures 1 to 6 As shown, the adjustable quick positioning fixture provided by this utility model includes a fixture body 1, a movable component 2, and an adaptive component 3, characterized in that:

[0029] The fixture body 1 has a clamping area 4 on its outside. A central shaft 12 is movably connected to the outside of the clamping area 4. A parallel shaft 13 is fixedly connected to the outside of the clamping area 4. A guide rail 14 is fixedly connected to the outside of the clamping area 4.

[0030] Active component 2 and adaptive component 3. Both active component 2 and adaptive component 3 have a first-level arc groove 11 on their exterior. Adaptive component 3 includes a first-level fan plate 6, a second-level fan plate 8 and a third-level fan plate 10.

[0031] The fixture body 1 has a structural compartment 5 on its exterior. The ends of the central shaft 12 and the parallel shaft 13 away from the fixture body 1 are located inside the structural compartment 5. A connecting gear 15 is fixedly connected to the exterior of the ends of the central shaft 12 and the parallel shaft 13 away from the fixture body 1. An adjusting handle 17 is movably connected inside the structural compartment 5. A transmission gear 18 is fixedly connected to the exterior of the adjusting handle 17. A transmission belt 16 is movably connected to the exterior of the connecting gear 15 at the ends of the central shaft 12 and the parallel shaft 13. The transmission gear 18 meshes with the connecting gear 15 at the end of the central shaft 12. The adjusting handle 17 is movably connected to the outer wall of the structural compartment 5. A secondary arc groove 7 is opened on the exterior of the primary fan plate 6. A tertiary arc groove 9 is opened on the exterior of the secondary fan plate 8. There are multiple sets of tertiary arc grooves 9, which are evenly distributed on the exterior of the secondary fan plate 8.

[0032] Specifically, when fixing workpieces of different models, rotating the adjustment handle 17 drives the transmission gear 18, which in turn drives the central shaft 12 and the transmission belt 16. Driven by the transmission belt 16, the central shaft 12 and the parallel shaft 13 rotate synchronously in the same direction, thereby making the movable component 2 move in parallel as a whole. By operating the adjustment handle 17, the position of the movable component 2 is adjusted to complete the clamping of workpieces of various models.

[0033] Example 2

[0034] Furthermore, the movable component 2 has a guide groove 19 and a threaded groove 20 on its exterior. The guide groove 19 is fitted and connected to the guide rail 14, and the threaded groove 20 is threaded and connected to the central shaft 12 and the parallel shaft 13. The vertical height of the central shaft 12 and the parallel shaft 13 is lower than that of the guide rail 14. There are multiple sets of primary arc grooves 11 symmetrically distributed on the exterior of the fixture body 1 and the movable component 2. There are two sets of secondary arc grooves 7 symmetrically distributed on the exterior of the primary fan plate 6. The primary fan plate 6 is fitted and connected to the primary arc groove 11. The secondary fan plate 8 is fitted and connected to the secondary arc groove 7. The tertiary fan plate 10 is fitted and connected to the tertiary arc groove 9. There are two sets of parallel shafts 13 symmetrically distributed on the exterior of the clamping area 4. There are two sets of guide rails 14 symmetrically distributed between the central shaft 12 and the parallel shaft 13. The workpiece 21 is movably connected between the fixture body 1 and the movable component 2.

[0035] By making the above settings, during the clamping operation, when the workpiece with an irregular outer surface comes into contact with the third-level fan plate 10, the third-level fan plate 10 rotates along the third-level arc groove 9 and makes it fit against the workpiece surface. After the fit is completed, the second-level fan plate 8 and the first-level fan plate 6 move inside the second-level arc groove 7 and the first-level arc groove 11 respectively and are parallel to each other with the workpiece contact surface, thereby maintaining a stable state and ensuring the clamping stability of the device. At the same time, in subsequent operations, the above operation can be repeated to clamp workpieces with different shaped surfaces, thus improving the applicability of the device.

[0036] The above description is only a preferred embodiment of the present utility model and is 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 should be included within the protection scope of the present utility model.
