Description

Technical Field

[0001] This utility model belongs to the field of welding clamping technology, specifically relating to a quick clamping mechanism for an inner and outer ring welding fixture. Background Technology

[0002] With the continuous development of modern manufacturing, especially in precision machining and welding processes, the requirements for equipment precision are gradually increasing. In particular, in industries such as automobiles, aerospace, and machinery manufacturing, the use of inner and outer ring welding fixtures is particularly widespread. Welding processes require high precision and stability, so welding fixtures play a crucial role in these fields. The design of welding fixtures not only affects the production efficiency of products, but also directly determines the quality and reliability of products.

[0003] A prior art patent publication number CN214418056U describes a welding fixture for circular rings, comprising a frame. The frame is equipped with an outer circular clamping module, an inner circular clamping module, and an annular protrusion. The outer circular clamping module is located outside the annular protrusion, and the inner circular clamping module is located inside the annular protrusion. The annular protrusion has an annular sliding hole, and multiple sliders are arranged within the annular sliding hole. A positioning block is connected above each slider, and the positioning block has a positioning groove. A locking screw is threadedly connected below each slider… This device uses a positioning block to position a connecting rod, and the outer and inner circular clamping modules to clamp the inner and outer rings, automatically positioning and splicing them for clamping, thus improving efficiency. However, in practical use, it still has the following shortcomings: In practice, the ring cannot rotate after clamping. When welding is required at multiple locations, if the ring cannot rotate, the operator needs to frequently adjust the position of the workpiece or welding torch, leading to a decrease in production efficiency.

[0004] Therefore, a quick clamping mechanism for inner and outer ring welding fixtures is needed to solve the problem in the existing technology where the ring cannot be rotated after clamping, which increases the complexity of the process and leads to a decrease in production efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a quick clamping mechanism for inner and outer ring welding fixtures to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick clamping mechanism for an inner and outer ring welding fixture, comprising a base, a fixing mechanism on the top of the base, a ring installed on the outside of the fixing mechanism, and an auxiliary stabilizing mechanism corresponding to the ring on the top of the base.

[0007] It should be noted in the solution that a shock-absorbing pad is fixedly connected to the bottom of the base.

[0008] It is further worth noting that the fixing mechanism includes a first support plate fixedly connected to the top of the base. A limit sleeve is fixedly connected to the top of the first support plate. A first synchronous wheel is rotatably connected to the inner wall of the limit sleeve. A cylinder is fixedly connected to the rear end of the first synchronous wheel. A push plate is fixedly connected to the output end of the cylinder through the first synchronous wheel. Multiple connecting plates are fixedly connected to the front end of the first synchronous wheel. Triangular rods are rotatably connected to the front ends of the multiple connecting plates. First connecting rods are rotatably connected to the front ends of the multiple connecting plates. Second connecting rods are rotatably connected to the front ends of the corresponding triangular rods and first connecting rods. Support plates are fixedly connected to the outer sides of the multiple second connecting rods. A second synchronous wheel is rotatably connected to the rear end of the first support plate near the bottom. Synchronous belts are installed on the outer walls of the first and second synchronous wheels. A servo motor corresponding to the second synchronous wheel is fixedly connected to the front end of the first support plate.

[0009] It should be further noted that the inner ends of all of the aforementioned triangular rods are rotatably connected to the outer ends of the connecting plate.

[0010] In a preferred embodiment, anti-slip pads are fixedly connected to the outer walls of the plurality of support plates.

[0011] In a preferred embodiment, the auxiliary stabilizing mechanism includes two second support plates fixedly connected to the top of the base. A stabilizing ring is fixedly connected to the top of the two second support plates. A plurality of threaded rods are rotatably connected to the outer wall of the stabilizing ring. A rotating plate is fixedly connected to the outer end of each of the plurality of threaded rods. A mounting plate is rotatably connected to the inner end of each of the plurality of threaded rods. A stabilizing wheel is rotatably mounted on the inner end of each of the plurality of mounting plates. Two guide rods are fixedly connected to the outer end of each of the plurality of mounting plates.

[0012] In a preferred embodiment, the outer wall of the stabilizing ring is provided with a plurality of threaded grooves corresponding to the threaded rod and a plurality of guide holes corresponding to the guide rod.

[0013] Compared with the prior art, the quick clamping mechanism for inner and outer ring welding fixtures provided by this utility model has at least the following beneficial effects:

[0014] (1) By setting a fixing mechanism, the ring is placed on the outside of multiple support plates. The cylinder is opened to drive the push plate to move. The push plate drives multiple triangular rods to rotate at the same time, so that multiple second connecting rods drive the support plates to move outward at the same time. Multiple support plates support and fix the inner wall of the ring, and the automatic clamping is completed quickly. When the ring needs to be rotated during welding, the servo motor is turned on to drive the second synchronous wheel to rotate. The synchronous belt drives the first synchronous wheel to rotate, so that the ring rotates at a uniform speed to cooperate with welding. After clamping, the ring can automatically rotate as needed. This reduces manual intervention, avoids the time loss of repeated adjustments, and improves production efficiency.

[0015] (2) By setting an auxiliary stabilizing mechanism, after the ring is clamped, the rotating plate drives the threaded rod to rotate. While the threaded rod rotates, it drives the mounting plate to move inward, so that multiple stabilizing wheels contact the outer wall of the ring, which plays an auxiliary stabilizing role for the ring and prevents the ring from shifting during welding rotation, thereby improving the welding accuracy and quality.

Detailed Implementation

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Please see Figure 1-4 This utility model provides a quick clamping mechanism for an inner and outer ring welding fixture, including a base 1, a fixing mechanism 2 on the top of the base 1, a ring 3 installed on the outside of the fixing mechanism 2, and an auxiliary stabilizing mechanism 4 corresponding to the ring 3 on the top of the base 1.

[0023] Further as Figure 1 and Figure 2 As shown, it is worth noting that the bottom of the base 1 is fixedly connected with a shock-absorbing pad. The shock-absorbing pad can effectively absorb and reduce the vibration caused by equipment operation, welding process or external impact, prevent these vibrations from being transmitted to other parts of the equipment, reduce errors or quality problems caused by vibration. By setting the shock-absorbing pad, the stability of the base can be enhanced, and the equipment can be prevented from changing position or shifting due to vibration during operation, thereby ensuring the accuracy and reliability of the entire welding fixture.

[0024] Further as Figure 3 As shown, it is worth noting that the fixing mechanism 2 includes a first support plate 201 fixedly connected to the top of the base 1. A limit sleeve 202 is fixedly connected to the top of the first support plate 201. A first synchronous wheel 203 is rotatably connected to the inner wall of the limit sleeve 202. A cylinder 204 is fixedly connected to the rear end of the first synchronous wheel 203. A push plate 205 is fixedly connected to the output end of the cylinder 204 through the first synchronous wheel 203. Multiple connecting plates 206 are fixedly connected to the front end of the first synchronous wheel 203. Triangular rods 207 are rotatably connected to the front end of each of the multiple connecting plates 206. A first connecting rod 208 is rotatably connected to the front end of each of the multiple connecting plates 206. A second connecting rod 209 is rotatably connected to the front end of the corresponding triangular rod 207 and the front end of the first connecting rod 208. The outer sides of the multiple second connecting rods 209 are... Each component is fixedly connected to a support plate 210. A second synchronous wheel 211 is rotatably connected to the rear end of the first support plate 201 near the bottom. A synchronous belt 212 is installed on the outer wall of the first synchronous wheel 203 and the outer wall of the second synchronous wheel 211. A servo motor 213 corresponding to the second synchronous wheel 211 is fixedly connected to the front end of the first support plate 201. By setting the fixing mechanism 2, automatic clamping can be completed quickly. When the ring 3 needs to be rotated during welding, simply turn on the servo motor 213 to drive the second synchronous wheel 211 to rotate, and the synchronous belt 212 will drive the first synchronous wheel 203 to rotate, so that the ring 3 rotates at a uniform speed to cooperate with welding. After clamping, the ring 3 can automatically rotate as needed, which reduces manual intervention, avoids the time loss of repeated adjustments, and improves production efficiency.

[0025] Further as Figure 3 As shown, it is worth noting that the inner ends of multiple triangular rods 207 are rotatably connected to the outer ends of the connecting plate 206. The movement of the connecting plate 206 provides a stable driving force for the rotation of the triangular rods 207, thereby driving the multiple support plates 210 to extend and retract.

[0026] Further as Figure 3 As shown, it is worth noting that anti-slip pads are fixedly connected to the outer walls of multiple support plates 210 to increase the friction between the support plates 210 and the surface of the ring 3, so that the ring 3 can rotate with the rotation of the multiple support plates 210 and avoid slippage or deviation.

[0027] As can be seen from the above working process: by setting the fixed mechanism 2, automatic clamping can be completed quickly. When the ring 3 needs to be rotated during welding, the servo motor 213 is turned on to drive the second synchronous wheel 211 to rotate, and the synchronous belt 212 drives the first synchronous wheel 203 to rotate, so that the ring 3 rotates at a uniform speed to cooperate with welding. After clamping, the ring 3 can automatically rotate as needed, which reduces manual intervention, avoids the time loss of repeated adjustments, and improves production efficiency.

[0028] Further as Figure 4As shown, it is worth noting that the auxiliary stabilizing mechanism 4 includes two second support plates 401 fixedly connected to the top of the base 1. A stabilizing ring 402 is fixedly connected to the top of the two second support plates 401. Multiple threaded rods 403 are rotatably connected to the outer wall of the stabilizing ring 402. A rotating plate 404 is fixedly connected to the outer end of each of the multiple threaded rods 403. A mounting plate 405 is rotatably connected to the inner end of each of the multiple threaded rods 403. A stabilizing wheel 406 is rotatably mounted on the inner end of each of the multiple mounting plates 405. Two guide rods 407 are fixedly connected to the outer end of each of the multiple mounting plates 405. By setting the auxiliary stabilizing mechanism 4, the multiple stabilizing wheels 406 contact the outer wall of the ring 3, which plays a role in stabilizing the ring 3 and preventing the ring 3 from shifting during welding rotation, thereby improving the welding accuracy and quality.

[0029] Further as Figure 4 As shown, it is worth noting that the outer wall of the stabilizing ring 402 has multiple threaded grooves corresponding to the threaded rod 403 and multiple guide holes corresponding to the guide rod 407. Under the action of the threaded grooves, the threaded rod 403 can move inward while rotating, providing driving force for the movement of the mounting plate 405. The guide holes cooperate with the guide rod 407 to limit the movement of the mounting plate 405.

[0030] This solution has the following working process: In actual use, the ring 3 is placed on the outside of multiple support plates 210. The cylinder 204 is opened to drive the push plate 205 to move. The push plate 205 drives multiple triangular rods 207 to rotate simultaneously, so that multiple second connecting rods 209 drive the support plates 210 to move outward simultaneously. The multiple support plates 210 support and fix the inner wall of the ring 3, and quickly complete the automatic clamping. After the ring 3 is clamped, the rotating plate 404 is rotated to drive the threaded rod 403 to rotate. While the threaded rod 403 is rotating, it drives the mounting plate 405 to move inward, so that multiple stabilizing wheels 406 contact the outer wall of the ring 3, which plays an auxiliary stabilizing role for the ring 3. When the ring 3 needs to be rotated during welding, the servo motor 213 is turned on to drive the second synchronous wheel 211 to rotate, and the synchronous belt 212 drives the first synchronous wheel 203 to rotate, so that the ring 3 rotates at a uniform speed to cooperate with welding.

[0031] In summary: By setting up the fixing mechanism 2, automatic clamping can be completed quickly. When the ring 3 needs to be rotated during welding, simply turn on the servo motor 213 to drive the second synchronous wheel 211 to rotate, and the synchronous belt 212 to drive the first synchronous wheel 203 to rotate, so that the ring 3 rotates at a uniform speed to cooperate with welding. After clamping, the ring 3 can automatically rotate as needed, which reduces manual intervention, avoids the time loss of repeated adjustments, and improves production efficiency. By setting up the auxiliary stabilizing mechanism 4, multiple stabilizing wheels 406 contact the outer wall of the ring 3, which plays an auxiliary stabilizing role for the ring 3, preventing the ring 3 from shifting during welding rotation, thereby improving the welding accuracy and quality.
