Description

Technical Field

[0001] This invention relates to the field of automatic bolt locking device technology, and more specifically, to a side-mounted automatic bolt locking mechanism. Background Technology

[0002] On automated production lines, bolts are typically tightened using automatic bolt locking devices, such as the movable automatic bolt and nut locking device disclosed in patent CN106826205B. This device fixes the assembly to a mounting frame, then uses an X-axis drive to move a nut fixing device and a rotating bolt device to the through-hole position on the assembly. A Y-axis drive then moves these devices longitudinally to automatically lock the bolts. However, this automatic locking device can only move the rotating bolt device in the X-axis direction to align it with the mounting hole; it cannot move left or right. For products with multiple rows of mounting holes, manual left-right movement is still required for alignment, making the operation cumbersome. Sometimes, products also require bolt tightening on the side, but this device can only tighten bolts vertically, resulting in low compatibility.

[0003] In view of this, the applicant hereby submits this application after studying the existing technology. Summary of the Invention

[0004] The present invention provides a side-mounted automatic bolt locking mechanism, which aims to improve at least one of the above-mentioned technical problems.

[0005] To solve the above-mentioned technical problems, the present invention provides a side-mounted automatic bolt locking mechanism, including an X-axis drive device, a Y-axis drive device, a Z-axis drive device, and a servo tightening module, wherein: The Y-axis drive device is connected to the X-axis drive device, and the X-axis drive device can drive the Y-axis drive device to reciprocate along the X-axis direction; the Z-axis drive device is connected to the Y-axis drive device, and the Y-axis drive device can drive the Z-axis drive device to reciprocate along the Y-axis direction; the servo tightening module is connected to the Z-axis drive device, and the Z-axis drive device can drive the servo tightening module to reciprocate along the Z-axis direction. The servo tightening module includes a drive unit, a tightening sleeve, and a vacuum generator. The tightening sleeve extends along the X-axis and is hollow inside. The vacuum generator is connected to the tightening sleeve so that the tightening sleeve can attract bolts. The drive unit is used to drive the tightening sleeve to rotate in order to tighten the bolts.

[0006] As a further optimization, an imaging system is also included, which is connected to the servo tightening module to assist the tightening sleeve in accurately adsorbing and tightening the bolt.

[0007] As a further optimization, the vacuum generator is connected to an adapter, the adapter has an air passage, the tightening sleeve passes through the adapter and through the air passage, and the side wall of the tightening sleeve has several through holes communicating with the air passage in the circumferential direction.

[0008] As a further optimization, the servo tightening module is connected to the Z-axis drive device via a bracket, and the drive component, the tightening sleeve, the vacuum generator, and the imaging system are all connected to the bracket.

[0009] As a further optimization, the Z-axis drive device is provided with a first slide, and the Z-axis drive device is connected to the Y-axis drive device through the first slide.

[0010] As a further optimization, the Y-axis drive device is provided with a second slide at the bottom, and the Y-axis drive device is connected to the X-axis drive device through the second slide.

[0011] As a further optimization, it also includes two parallel support bases, which extend along the X-axis direction and are arranged on both sides of the X-axis drive device, and the second slide is slidably connected to the two support bases.

[0012] As a further optimization, a control module is also included, which is used to control the operation of the X-axis drive device, the Y-axis drive device, the Z-axis drive device, and the servo tightening module.

[0013] By adopting the above technical solution, the present invention can achieve the following technical effects: This application discloses a side-mounted automatic bolt-locking mechanism. Through X-axis, Y-axis, and Z-axis drive devices, a servo tightening module can move along the X, Y, and Z axes, allowing the servo tightening module to move in three dimensions. After attracting the bolt, it automatically aligns with the hole in the part to be locked, tightening the bolt into the hole, achieving full automation without manual positioning. Furthermore, the tightening sleeve of the servo tightening module extends along the X-axis, parallel to the X-axis drive device. When the X-axis drive device is mounted on a horizontal base, the Y-axis and Z-axis drive devices move the servo tightening module left-right and up-down, aligning the tightening sleeve with the hole in the part. The X-axis drive device moves the servo tightening module closer to the hole, while the drive component rotates the tightening mechanism, enabling side-mounted bolt locking. Similarly, when the X-axis drive device is mounted on a vertical base, it enables vertical bolt locking, thus making it compatible with multiple products. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0017] Example Depend on Figure 1 , Figure 2 As shown, this embodiment of the invention provides a side-mounted automatic bolt locking mechanism, including an X-axis drive device 1, a Y-axis drive device 2, a Z-axis drive device 3, and a servo tightening module, wherein: The Y-axis drive device 2 is connected to the X-axis drive device 1, and the X-axis drive device 1 can drive the Y-axis drive device 2 to reciprocate along the X-axis direction; the Z-axis drive device 3 is connected to the Y-axis drive device 2, and the Y-axis drive device 2 can drive the Z-axis drive device 3 to reciprocate along the Y-axis direction; the servo tightening module is connected to the Z-axis drive device 3, and the Z-axis drive device 3 can drive the servo tightening module to reciprocate along the Z-axis direction. The servo tightening module includes a drive unit 41, a tightening sleeve 42, and a vacuum generator 43. The tightening sleeve 42 extends along the X-axis and is hollow inside. The vacuum generator 43 communicates with the tightening sleeve 42 to allow the tightening sleeve 42 to attract bolts. The drive unit 41 drives the tightening sleeve 42 to rotate and tighten the bolts. The drive unit 41 can be a rotary motor or the like.

[0018] In this embodiment, the servo tightening module achieves three-dimensional motion through the drive of X-axis drive device 1, Y-axis drive device 2, and Z-axis drive device 3. It first vacuum-adsorbs the bolt, then aligns the bolt with the hole in the locked part and tightens it, achieving full automation. When X-axis drive device 1 is installed on a horizontal base, it can automatically tighten bolts from the side; when installed on a vertical base, it can automatically tighten bolts vertically. This mechanism has a simple and reliable structure, is easy to adjust, and is applicable to multiple products, exhibiting high compatibility.

[0019] Furthermore, it also includes an imaging system 5, which is connected to the servo tightening module. The imaging system 5 can identify whether the tightening sleeve 42 has correctly attracted the bolt and whether the hole of the locked part is aligned, thereby assisting the tightening sleeve to accurately attract and tighten the bolt.

[0020] like Figure 3 As shown, the vacuum generator 43 is connected to an adapter 44. The adapter 44 has an air passage 45 communicating with the vacuum generator 43. The tightening sleeve 42 passes through the adapter 44 and can rotate within it. The tightening sleeve 42 also passes through the air passage 45, and several through holes 46 are circumferentially formed on the side wall of a section within the air passage 45, thus connecting the tightening sleeve 42 to the air passage 45. By providing the adapter 44, the tightening sleeve 42 can always maintain communication with the vacuum generator 43, preventing its connection from being affected by rotation. The adapter 44 also has sealing devices on both the inlet and outlet sides of the tightening sleeve 42 to prevent air leakage.

[0021] like Figure 1 and Figure 2As shown, the servo tightening module is connected to the Z-axis drive device 3 via a bracket 47. The drive component 41, the tightening sleeve 42, the vacuum generator 43, and the imaging system 5 are all connected to the bracket 47. The Z-axis drive device 3 has a first slide 31, which connects it to the Y-axis drive device 2. The bottom of the Y-axis drive device 2 has a second slide 21, which connects it to the X-axis drive device 1. The X-axis drive device 1, Y-axis drive device 2, and Z-axis drive device 3 can be electric cylinders. Two parallel support bases 11 are also provided at the bottom of the second slide 21. These two support bases 11 are respectively arranged on both sides of the X-axis drive device 1 and are parallel to it. The second slide 21 is slidably connected to the two support bases 11. The support bases 11 can be used to connect to a base; by providing two support bases 11, the overall stability of the mechanism can be improved.

[0022] Furthermore, it also includes a control module, which is used to control the operation of the X-axis drive device 1, Y-axis drive device 2, Z-axis drive device 3, and servo tightening module. The control module can also acquire information from the imaging system 5 and process the acquired information into control information to control the operation of the mechanism.

[0023] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
