[0016] This utility model provides an automatic screw-driving assembly fixture, the structure and operating principle of which are described in conjunction with the attached... Figure 1 To be continued Figure 3 Please provide a detailed explanation. For example... Figure 1 As shown, the base 1 of the automatic screw-driving assembly fixture is a rectangular frame structure. A groove 2 is formed on the top of the base 1, with a T-shaped cross-section. A slider 3 is embedded inside the groove 2, and the bottom of the slider 3 has a protrusion that matches the groove 2. The slider 3 engages with the groove 2 through the protrusion, ensuring stable movement of the slider 3 within the groove 2. The top of the slider 3 is fixedly connected to the positioning module 4 by bolts. The outer wall of the positioning module 4 has several positioning holes arranged in a circular array with threads on the inner wall for subsequent product fixing. The bottom of the positioning module 4 has a guide groove, inside which a guide block 10 is slidably installed. The bottom of the guide block 10 is connected to the top of the guide assembly 6, and the bottom of the guide assembly 6 is fixedly connected to the base plate by bolts.
[0017] like Figure 2As shown, an adjusting assembly 5 is fixedly installed on one side of the base 1. The output end of the adjusting assembly 5 has a lead screw with threads on its outer wall. The top end of the lead screw is threaded to the bottom of the slider 3, and the bottom end of the lead screw is rotatably connected to the side wall of the base 1. A bearing is fitted onto the outer wall of the lead screw, and the outer ring of the bearing is fixedly connected to the side wall of the base 1. The input end of the adjusting assembly 5 has a transmission gear with teeth on its outer wall. The teeth of the transmission gear mesh with the output end of the drive module 8, and the central shaft of the transmission gear is rotatably connected to the side wall of the base 1. The drive module 8 is fixedly installed on the top of the base 1. The output end of the drive module 8 is connected to the input end of the adjusting assembly 5. The action of the drive module 8 drives the transmission gear to rotate, thereby driving the lead screw to rotate and causing the slider 3 to move along the slide groove 2.
[0018] A locking mechanism 7 is rotatably mounted inside the positioning module 4. The outer wall of the locking mechanism 7 has several locking teeth with a serrated structure and their tips facing the center of the positioning module 4. A spring plate with an arc-shaped structure is located on the inner wall of the locking mechanism 7. The arc-shaped surface of the spring plate fits against the inner wall of the positioning module 4, with one end embedded in the inner wall and the other end in contact with it. A drive gear is located at the top of the locking mechanism 7. The outer wall of the drive gear has teeth that mesh with the locking teeth. The central shaft of the drive gear is rotatably connected to the inner wall of the positioning module 4. A keyway is located on the central shaft of the drive gear, and a drive key is embedded inside the keyway. One end of the drive key is connected to the output end of the drive module 8. When the drive module 8 operates, the drive key drives the drive gear to rotate. The rotation of the drive gear further drives the locking mechanism 7 to rotate, thereby releasing the locking teeth from their fixed state on the positioning module 4, allowing the positioning module 4 to adaptively adjust according to changes in product specifications.
[0019] like Figure 3 As shown, the guide assembly 6 has a guide rod 9 at its top, a guide groove on its outer side wall, and a guide block 10 slidably mounted inside the guide groove. The top of the guide block 10 is connected to the bottom of the positioning module 4, and the bottom of the guide rod 9 is connected to the base plate by bolts. A spring is provided on the outer side wall of the guide rod 9, with one end embedded in the outer wall of the guide rod 9 and the other end in contact with the bottom of the guide block 10. A guide head is provided at the top of the guide rod 9, and a ball bearing is provided on the outer side wall of the guide head. The outer surface of the ball bearing is in contact with the inner wall of the guide groove. The guide assembly 6 plays a guiding role during the adjustment of the positioning module 4, ensuring that the movement trajectory of the positioning module 4 is accurate and stable.
[0020] In practical applications, a support column is fixedly installed at the bottom of the base 1, a base plate is fixedly installed at the bottom end of the support column, and a guide assembly 6 is fixedly installed at the top of the base plate. When different specifications of products need to be assembled, the operator starts the drive module 8. The drive module 8 drives the lead screw of the adjustment assembly 5 to rotate through the transmission gear. The rotation of the lead screw causes the slider 3 to move along the slide groove 2, thereby driving the positioning module 4 to adjust its position. At the same time, the drive module 8 drives the drive gear of the locking mechanism 7 to rotate through the drive key. The rotation of the drive gear causes the locking mechanism 7 to release the fixed state of the positioning module 4, so that the positioning module 4 can adaptively adjust according to changes in product specifications. The guide assembly 6 plays a guiding role in the adjustment process of the positioning module 4. The cooperation between the ball bearing on the guide rod 9 and the guide groove ensures that the movement trajectory of the positioning module 4 is accurate and stable. After the positioning module 4 is adjusted to the appropriate position, the locking mechanism 7 re-fixes the position of the positioning module 4, completing the adjustment process of the assembly fixture.
[0021] The above embodiments describe in detail the structural composition and working principle of this utility model. Through the cooperation between the base 1, slide 2, slider 3, positioning module 4, adjustment component 5, guide component 6, locking mechanism 7 and drive module 8, the automatic adjustment function of the automatic screw-driving assembly fixture is realized, which meets the needs of rapid switching of various product models.
[0022] To enable those skilled in the art to fully understand and implement this utility model, the operating principle and operation steps of the automatic screw-driving assembly fixture are explained in detail below in conjunction with specific application scenarios.
[0023] In the actual assembly process, the product to be assembled is first placed on the positioning module 4 and initially fixed through the positioning holes on the outer wall of the positioning module 4. If the product specifications change at this point, the position and angle of the assembly fixture need to be adjusted to adapt to the new assembly requirements. The operator starts the drive module 8, whose output drives the transmission gear in the adjustment assembly 5 to rotate. The teeth of the transmission gear mesh with the lead screw, thereby driving the lead screw to rotate. The rotation of the lead screw, through a threaded connection, pushes the slider 3 to move along the slide groove 2. The bottom protrusion of the slider 3 engages with the T-shaped structure of the slide groove 2, ensuring the stability of the slider 3 during movement. The movement of the slider 3 further drives the positioning module 4 to adjust its position to adapt to the assembly requirements of products with different specifications.
[0024] Meanwhile, the movement of the drive module 8 is also transmitted to the drive gear of the locking mechanism 7 via the drive key. The teeth of the drive gear mesh with the locking teeth, and the rotation of the drive gear drives the entire locking mechanism 7 to rotate. The locking teeth of the locking mechanism 7 have a sawtooth structure, with their tips facing the center of the positioning module 4. During rotation, they gradually release the fixing state of the positioning module 4. This design allows the positioning module 4 to adaptively adjust according to changes in product specifications. The spring plate inside the locking mechanism 7 has an arc-shaped structure, and its arc-shaped surface fits against the inner wall of the positioning module 4. When the locking mechanism 7 rotates, the spring plate undergoes elastic deformation, thereby releasing the constraint force on the positioning module 4, facilitating the free movement of the positioning module 4.
[0025] During the adjustment of the positioning module 4, the guide component 6 plays a crucial guiding role. The guide groove at the bottom of the positioning module 4 is slidably connected to the guide block 10, and the bottom of the guide block 10 contacts the guide head at the top of the guide rod 9. The ball bearings on the guide head can roll on the inner wall of the guide groove, thereby reducing friction and ensuring that the movement trajectory of the positioning module 4 is accurate and stable. In addition, the spring on the outer wall of the guide rod 9 applies a certain preload to the guide block 10 through elasticity. This preload not only eliminates the gap between the guide block 10 and the guide groove, but also effectively suppresses the shaking of the positioning module 4 during movement, further improving the adjustment accuracy.
[0026] Once the positioning module 4 is adjusted to the appropriate position, the drive module 8 stops operating, and the locking mechanism 7 rotates back to its initial state under the restoring force of the spring plate. The locking teeth engage with the inner wall of the positioning module 4 again, thus fixing the positioning module 4 in the new position. At this point, the assembly fixture has completed the adaptation and adjustment for products of different specifications, and subsequent screw-driving operations can continue.
[0027] As can be seen from the above steps, the automatic screw-driving assembly fixture of this utility model achieves automatic adjustment of the fixture's position and angle through the coordinated operation of the drive module 8, adjustment component 5, locking mechanism 7, and guide component 6. The interlocking structure of the slide groove 2 and the slider 3 ensures the stability of the positioning module 4 during movement, while the design of the locking mechanism 7 enables quick unlocking and locking of the positioning module 4, significantly improving adjustment efficiency. In addition, the cooperation between the ball bearings and the guide groove in the guide component 6, as well as the pre-tensioning effect of the spring, ensures the accuracy and stability of the positioning module 4 during adjustment, thereby meeting the needs of rapid switching between various product models.
[0028] The above embodiments describe in detail the specific application scenarios and operating principles of this utility model. Through the close cooperation between the base 1, slide 2, slider 3, positioning module 4, adjustment component 5, guide component 6, locking mechanism 7 and drive module 8, the efficient and flexible adjustment function of the automatic screw-driving assembly fixture is realized, which effectively solves the problems of time consumption and accuracy reduction caused by manual adjustment in the prior art, while improving production efficiency and equipment adaptability.
[0029] 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 and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
