Description

Technical Field

[0001] This utility model relates to the field of screw machine technology, and more specifically, to a multi-axis cooperative locking mechanism for screw machines. Background Technology

[0002] A screw tightening machine is a mechanical device used for automating screw tightening, primarily to improve production efficiency and reduce manual labor intensity. Its core feature is the precise positioning and rapid tightening of screws through a mechanical structure. It is widely used in manufacturing industries such as electronics, automobiles, and home appliances. However, existing screw tightening machines still have the following shortcomings in their locking mechanisms:

[0003] (1) Most existing screw fastening mechanisms can only operate on a single axis and can only fasten one screw at a time. If the product requires multiple screws, multiple cycles are required, significantly extending the overall cycle time. For different products or screw positions, the mechanical structure needs to be frequently adjusted or reprogrammed, resulting in long line change times.

[0004] (2) When switching between different specifications of parts for fastening, it is necessary to completely replace the fixed mold and readjust the equipment, which makes it impossible to process parts of multiple specifications and affects the continuity of production. To address this, a multi-axis cooperative fastening mechanism for screw machines is proposed. Utility Model Content

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0027] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0028] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0029] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0030] like Figure 1As shown, this embodiment proposes a multi-axis cooperative locking mechanism for a screw machine, including a base plate 1. The top of the base plate 1 is provided with a locking mechanism 2 for simultaneously tightening multiple screws. The bottom of the locking mechanism 2 is provided with a fixing component 3 for clamping the part to be tightened. A lifting component 4 is provided on one side of the fixing component 3 to facilitate adjusting the locking height.

[0031] like Figure 3 , Figure 4 and Figure 5 As shown, the locking mechanism 2 includes a rectangular plate 201 disposed on the top of the base plate 1. A motor 202 is bolted to the top of the rectangular plate 201, which serves as the mounting carrier for the motor 202. The motor 202 provides the power source. A first universal joint 203 is fixedly connected to the output end of the motor 202. A universal rod 204 is rotatably connected to the bottom of the first universal joint 203. The first universal joint 203 transmits the rotational torque of the motor 202 to the universal rod 204, allowing for angular displacement between axes and compensating for positional deviations in multi-axis motion. The universal rod 204... A connecting rod 205 is slidably connected to the bottom of component 4. The connecting rod 205 transmits torque and allows axial extension and contraction, ensuring synchronization during independent multi-axis movement. A second universal joint 206 is rotatably connected to the bottom of the connecting rod 205. A driven rod 207 is fixedly connected to the bottom of the second universal joint 206. A screwdriver 208 is fixedly connected inside the driven rod 207. The second universal joint 206 transmits torque from the connecting rod 205 to the driven rod 207, further compensating for angular errors and ensuring that the axis of the screwdriver 208 is aligned with the screw hole. The driven rod 2... The external sliding connection of 07 is a sleeve 209, which wraps around the driven rod 207 to limit its radial displacement and ensure the locking perpendicularity. An electric discharge head 210 is provided at the bottom of the sleeve 209. A feed pipe 211 is connected to the side wall of the electric discharge head 210, which transports screws from the feeder body 212 to the electric discharge head 210, achieving a continuous screw supply. The other end of the feed pipe 211 is connected to the feeder body 212. There are four lifting components 4, arranged in pairs opposite each other. An adjustment component 213 is provided on one side of the sleeve 209. During use, the feeder body 212 uses air pressure to sort and deliver screws to the feed pipe 211. The screws enter the electric discharge head 210 through the feed pipe 211. The motor 202 drives the first universal shaft 203 to rotate. The torque is transmitted to the second universal shaft 206 through the universal rod 204 and the connecting rod 205, which finally drives the screwdriver 208 in the driven rod 207 to rotate, thereby locking the screws onto the surface of the parts. Four screws can be locked at one time, shortening the production time and improving the production efficiency.

[0032] like Figure 5As shown, the adjustment assembly 213 includes an adjustment plate 2131 disposed at the bottom of the rectangular plate 201. The adjustment plate 2131 serves as the mounting base for the adjustment assembly 213, providing rigid support in the horizontal direction. A sliding hole 2132 is provided at the top of the adjustment plate 2131, and an adjustment component 2133 is slidably connected to the top of the sliding hole 2132. The sliding hole 2132 forms a linear motion guide rail for the adjustment component 2133, ensuring adjustment accuracy. The horizontal position of the adjustment component 2133 can be manually adjusted. A positioning hole 2134 is provided at the top of the adjustment component 2133, which is used to fix the position of the adjustment component 2133 to prevent displacement during the locking process. A positioning component 2135 is slidably connected inside the positioning hole 2134, which fixes the adjustment component 2133 at the designated position of the sliding hole 2132, ensuring the repeatability and positioning accuracy of the locking point. An adjusting clip 2136 is provided on the inner wall of the adjusting component 2133 near the sleeve 209 and is slidably connected to the sleeve 209. The adjusting clip 2136 controls the lifting and lowering movement of the sleeve 209 through clamping force, realizing the vertical fine adjustment of the screwdriver 208 and compensating for the height difference of the parts. In use, the adjusting component 2133 slides horizontally along the sliding hole 2132 of the adjusting plate 2131 and is manually driven to adjust to the target position. The positioning component 2135 is inserted into the positioning hole 2134 at the top of the adjusting component 2133 and locked to fix the horizontal position. The adjusting clip 2136 slides vertically along the outer wall of the sleeve 209 and finely adjusts the height of the screwdriver 208 by spiral adjustment, so that the axis of the screwdriver 208 is precisely aligned with the screw hole. The adjusting component 2133 and the adjusting clip 2136 are compatible with different specifications of sleeves 209 and screwdrivers 208, and can also adapt to different locking positions, improving the versatility of the equipment.

[0033] like Figure 6As shown, the fixing assembly 3 includes a support rod 301 located at the bottom of the electric discharge head 210. The support rod 301 serves as the vertical pillar of the entire fixing assembly 3, providing rigid support. A rotating component 302 is rotatably connected to the outer wall of the top of the support rod 301. The rotating component 302 adopts a cross-shaped design, converting rotational motion into four-way expansion and contraction motion. Assembly components 303 are hinged to all four ends of the rotating component 302. A moving component 304 is hinged to one end of each of the four assembly components 303. The assembly components 303 push the moving component 304 to move linearly along the guide rail of the slide plate 306, converting rotational torque into horizontal pushing and pulling force. Fixing components 305 are provided on the top of the four moving components 304. The fixing components 305 directly contact the surface of the part and provide friction to ensure that the part does not shift during the locking process. The slide plate 306 is fixedly connected to the top of the support rod 301. The top of the slide plate 306 has notches 307 at each of its four corners, which are slidably connected to the moving parts 304. The notches 307 at the four corners of the slide plate 306 serve as linear guides for the moving parts 304, ensuring the accuracy of the movement direction. The bottoms of the two opposing moving parts 304 are fixedly connected to two first cylinders 308, which are horizontally set. The two first cylinders 308 drive the opposing moving parts 304 to move closer or further away synchronously. In use, the first cylinders 308 extend horizontally and push the moving parts 304 to slide outward synchronously along the slide plate 306. The moving parts 304 drive the rotating parts 302 to rotate through the assembly parts 303, converting the horizontal movement into a four-way synchronous clamping force. The fixing parts 305 contact the side of the parts to be locked and fix the parts to be locked, avoiding displacement during the locking process, realizing the precise positioning and flexible fixing of the parts, and adapting to the efficient locking needs of multi-specification products.

[0034] like Figure 7As shown, the lifting assembly 4 includes a worktable 401 fixedly connected to the top of the base plate 1. Two uprights 402 are fixedly connected to one side of the top of the worktable 401. A top plate 403 is fixedly connected to the top of the two uprights 402. The uprights 402 vertically connect the worktable 401 and the top plate 403 to form a rigid frame to prevent lifting deviation. A second cylinder 404 is provided on the top of the top plate 403. The top plate 403 ensures the reaction force support of the second cylinder 404 during operation. The output end of the second cylinder 404... A first locking block 405 is fixedly connected, and a lead screw 406 is fixedly connected to the bottom of the first locking block 405 and slidably connected to the adjusting plate 2131. A first spring 407 is sleeved on the outside of the lead screw 406 and fixedly connected to the bottom of the locking block and the top of the rectangular plate 201. A second locking block 408 is threadedly connected to the outer wall of the bottom of the lead screw 406. A second spring 409 is fixedly connected to the bottom of the second locking block 408 and fixedly connected to the top of the adjusting plate 2131. The first locking block 405 is connected to the second spring 409. Cylinder 404 and lead screw 406 convert the push-pull force of the second cylinder 404 into rotational or linear motion of the lead screw 406. The second locking block 408 is threadedly connected to the lead screw 406 and can adjust the preload of the second spring 409 to adapt to different load requirements. The lead screw 406 drives the adjusting plate 2131 to rise and fall through linear sliding. The first spring 407 connects the first locking block 405 and the rectangular plate 201 to buffer the impact of starting the second cylinder 404. The second spring 409 provides a reverse pulling force to balance the screwdriver 2 during locking. When the screwdriver 208 is in use, the second cylinder 404 extends, pushing the first locking block 405 to press down the screw 406. The screw 406 descends linearly along the guide rod 402, causing the adjusting plate 2131 and the locking mechanism 2 to move down as a whole, locking the parts below. When the second cylinder 404 retracts, the screw 406 rises, and the first spring 407 and the second spring 409 assist in the reset, reducing mechanical impact and ensuring the verticality of the screwdriver 208, avoiding locking deviation caused by the screwdriver 208 tilting.

[0035] like Figure 2 As shown, a third spring 5 is sleeved on the outside of the universal rod 204. A limiting member 6 is fixedly connected to the bottom of the universal rod 204. A limiting hole 7 is opened on the outer wall of the connecting rod 205 and is slidably connected to the limiting member 6. The third spring 5 is sleeved on the outside of the universal rod 204. When the screwdriver 208 contacts the surface of the part or is fastened, the third spring 5 absorbs the impact force through compression to avoid the screw slipping or the part being crushed due to hard contact. The limiting member 6 and the limiting hole 7 limit the range of movement of the universal rod 204 to prevent the third spring 5 from overload failure or the universal rod 204 from coming off the connecting rod 205, thus ensuring operational safety.

[0036] like Figure 1As shown, the bottom of the two first cylinders 308 is fixedly connected to the C-shaped parts 8, and the bottom of the two C-shaped parts 8 is rotatably connected to the support wheels 9. The support wheels 9 improve the stability of the two first cylinders 308, reduce vibration, and extend the service life of the first cylinders 308.

[0037] like Figure 1 As shown, the four fasteners 305 are made of silicone and are circular in shape. The softness of the silicone material can prevent direct rigid contact with the surface of the parts and prevent scratches on the coating of the parts during the fixing process.

[0038] Specifically, when using the multi-axis coordinated locking mechanism of this screw machine: First, programming is performed on an external PLC controller to ensure that the mechanism can automatically perform coordinated locking operations. Then, the first cylinder 308 extends horizontally, pushing the moving part 304 to slide outward synchronously along the slide plate 306. The moving part 304 drives the rotating part 302 to rotate through the assembly part 303, converting the horizontal motion into a four-way synchronous clamping force. The fixing part 305 contacts the side of the part (e.g., ...). Figure 6 (As shown), then the second cylinder 404 extends, pushing the first locking block 405 to press down the lead screw 406. The lead screw 406 descends linearly along the guide rod 402, causing the adjusting plate 2131 and the locking mechanism 2 to move down as a whole. After adjusting to the designated position, it stops (as shown). Figure 7 (As shown), then the adjusting member 2133 slides horizontally along the sliding hole 2132 of the adjusting plate 2131, and is manually adjusted to the target position. The positioning member 2135 is inserted into the positioning hole 2134 at the top of the adjusting member 2133 and locked to fix the horizontal position. The adjusting clamp 2136 slides vertically along the outer wall of the sleeve 209. The height of the screwdriver 208 is finely adjusted by the screwdriver to make the axis of the screwdriver 208 precisely aligned with the screw hole (as shown). Figure 5 (As shown), the feeder body 212 then uses air pressure to sort and convey the screws to the feed pipe 211. The screws enter the electric discharge head 210 through the feed pipe 211. The motor 202 drives the first universal joint 203 to rotate, and the torque is transmitted to the second universal joint 206 through the universal rod 204 and the connecting rod 205. Finally, it drives the screwdriver 208 in the driven rod 207 to rotate, thereby fastening the screw to the surface of the part (e.g., ...). Figure 3 and Figure 4 (As shown).

[0039] All technical features in this embodiment can be freely combined according to actual needs.

[0040] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
