Detailed Implementation

[0014] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0016] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example

[0017] Reference Figure 1-4 This is an embodiment of the present invention, which provides a bolt adaptive clamping and positioning device, including a clamping mechanism 100.

[0018] Specifically, the clamping mechanism 100 includes a clamping platform 101 and a main clamping member 102 located on the surface of the clamping platform 101, which is used to clamp and position the bolt.

[0019] Furthermore, the main clamping member 102 includes a fixed seat 102a fixed at the center of the surface of the clamping platform 101. The surface of the fixed seat 102a has a plurality of guide grooves 102b arranged in a circular array. Below the fixed seat 102a is a rotatable adjusting plate 102c. The surface of the adjusting plate 102c has a plurality of adjusting grooves 102d arranged in a circular array. Each adjusting groove 102d has a movable slide 102e movably embedded inside it. The top of each slide 102e is fixed with a clamping plate 102f that contacts and positions the bolt. The guide grooves 102b, adjusting grooves 102d, slides 102e, and clamping plates 102f are provided in corresponding quantities. The guide groove 102b is set horizontally along the radial direction of the fixed base 102a, providing a precise linear trajectory for the radial movement of the clamping assembly and ensuring that the clamping center remains consistent. At the same time, the adjustment groove 102d is set in an arc shape, and its arc contour is precisely calculated to efficiently convert the rotational motion of the adjustment disc 102c into the radial linear motion of the clamping assembly. Thus, through the rotation of the adjustment disc 102c, under the relative rotation of the adjustment groove 102d and the guide groove 102b, multiple slide blocks 102e can move towards each other in the radial direction of the fixed base 102a, thereby driving the clamping plate 102f to move closer to or away from the center, realizing the clamping and loosening drive of the bolt.

[0020] Furthermore, the upper and lower ends of the slide 102e are located in the guide groove 102b and the adjustment groove 102d respectively. This structure with upper and lower double grooves makes the slide 102e move smoothly and prevents the clamping plate 102f from separating from the fixed seat 102a.

[0021] It also includes a positioning member 103 for positioning the main clamping member 102, which is located on the outer periphery of the bottom surface of the main clamping member 102. The positioning member 103 includes a follower ring 103a that rotates synchronously with the adjustment plate 102c, and the bottom surface of the follower ring 103a has a positioning opening 103b.

[0022] A locking member 104 is provided at the bottom of the positioning member 103 to abut against it. The rotation of the adjusting plate 102c can be locked by the abutment between the locking member 104 and the positioning member 103. The locking member 104 includes a locking frame 104b fixed to the outer wall of the lower section of the fixed base 102a. A locking rod 104a passes through the outer end of the locking member 104, and a lever arm 104c passes through the bottom of the locking rod 104a. The locking rod 104a is threaded on the outside. The locking rod 104a and the locking frame 104b are threaded together. The threaded engagement provides reliable self-locking performance, ensuring that the locking state remains stable under vibration conditions and realizing precise control of the locking force. At the same time, the lever arm 104c significantly increases the operating lever arm, allowing the operator to rotate the locking rod 104a in and out with less force, making the locking and unlocking operations more effortless and quick.

[0023] Preferably, the positioning port 103b is spirally arranged around the periphery of the follower ring 103a, and the locking rod 104a and the positioning port 103b are in abutting fit. This unique spiral design allows the locking rod 104a to engage with the positioning port 103b at different depths, corresponding to different rotation angles of the adjustment disc 102c, thereby realizing multi-level or stepless fine-tuning locking function, and thus ensuring the stability of the clamping plate 102f when clamping the bolt.

[0024] Furthermore, an auxiliary clamping component 105 is provided on the outer side of the clamping plate 102f, which can increase the contact points between the clamping plate 102f and the bolt when clamping the bolt.

[0025] The auxiliary clamping component 105 includes an adjusting rod 105a rotatably mounted on the outer wall of the clamping plate 102f. A movable frame 105b is mounted on the outside of the adjusting rod 105a. Auxiliary positioning rods 105c are mounted at both ends of the movable frame 105b. The auxiliary positioning rods 105c pass through the clamping plate 102f. The auxiliary positioning rods 105c not only move with the movable frame 105b, but also guide and prevent the movable frame 105b from rotating, ensuring its movement accuracy. The movable frame 105b and the adjusting rod 105a are threaded together. Rotating the adjusting rod 105a can realize the horizontal adjustment of the movable frame 105b. That is, by finely rotating the adjusting rod 105a, the extension length of the auxiliary positioning rod 105c can be finely adjusted, so that it forms an additional auxiliary support point at the bolt head or rod part, improving the stability and adaptability of clamping.

[0026] In use, the bolt to be processed is first placed between multiple clamping plates 102f. Then, the adjusting disc 102c is rotated, and the arc-shaped adjusting grooves 102d arranged in a ring on its surface will move relative to the radial guide grooves 102b on the fixed seat 102a. This movement forces the slide block 102e, which is embedded in the double grooves, to produce a precise radial linear displacement, thereby synchronously driving all clamping plates 102f to move towards the center, realizing automatic centering and clamping of bolts of different specifications. Subsequently, by screwing the locking rod 104a with the force-increasing arm 104c, its end is tightly pressed against the spiral rising positioning port 103b at the bottom of the follower ring 103a. Utilizing the self-locking performance of the thread and the locking effect of the spiral positioning port 103b, the adjusting disc 102c is firmly locked, ensuring that the clamping state is stable and does not loosen during operation. In addition, for special bolts, the adjusting rods 105a on each clamping plate 102f can be rotated independently, and the moving frame 105b and auxiliary positioning rod 105c can be driven by threaded transmission to make horizontal fine adjustments, so that they can extend to increase the contact points with the bolt, form auxiliary support, and further enhance the reliability and adaptability of clamping.

[0027] The coordinated arrangement of the arc-shaped adjustment groove 102d and the radial guide groove 102b enables synchronous, smooth, and high-precision radial movement of multiple clamping plates 102f, ensuring automatic alignment and stable clamping of bolts. Furthermore, the cooperation of the spiral positioning port 103b and the threaded locking rod 104a with the force-amplifying arm 104c provides reliable self-locking force and multi-position fine-tuning capability, making locking operation labor-saving and quick, and exhibiting excellent vibration resistance, effectively preventing loosening during processing. Simultaneously, the added independently adjustable auxiliary clamping component 105, by forming additional adjustable support points on the outside of the clamping plate 102f, significantly increases the contact area and constraint points with the bolts, greatly improving the clamping adaptability and overall stability for non-standard or easily damaged bolts, making the device versatile, reliable, and highly precise.
