Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a fixture for drilling and chamfering aluminum products. Background Technology

[0002] Aluminum products are a general term for household and industrial products made primarily from aluminum alloys. Aluminum alloys are a general term for alloys based on aluminum. The main alloying elements are copper, silicon, magnesium, zinc, and manganese, while minor alloying elements include nickel, iron, titanium, chromium, and lithium.

[0003] After aluminum products are formed, they need to be chamfered and drilled. During the processing, clamps are needed to hold the aluminum products in place to prevent them from shifting. In the existing technology, clamps generally rely on springs to provide clamping force. After clamping, the clamps are prone to backing out, which leads to insufficient clamping force during assembly. As a result, the aluminum products are still prone to loosening under stress. Utility Model Content

[0004] The purpose of this utility model is to address the deficiencies of the prior art by providing a limiting fixture for drilling and chamfering aluminum products, thereby solving the problems mentioned in the background art.

[0005] A limiting fixture for drilling and chamfering aluminum products includes a worktable. Four downwardly protruding legs are fixedly installed at the bottom corners of the worktable. Two clamping plates are slidably connected to the top of the worktable. An anti-reverse rotation mechanism is installed at the bottom of the worktable. A linkage mechanism is connected to the output end of the anti-reverse rotation mechanism. The linkage mechanism is connected to the clamping plates. Downwardly protruding sliding rods are integrally formed at both ends of the bottom of the clamping plates. A sliding groove is provided inside the worktable for the sliding rods to slide axially.

[0006] By adopting the above technical solution, the anti-reverse rotation mechanism drives the linkage mechanism to move. The linkage mechanism moves the two clamping plates in opposite directions. The clamping plates moving in opposite directions drive the sliding rod to move in the sliding groove, thereby realizing the axial movement of the clamping plates. The clamping plates moving in opposite directions can clamp the aluminum products.

[0007] The anti-reverse rotation mechanism includes a mounting bracket fixedly connected to the bottom end of the workbench. Worms are rotatably mounted on the inner side of one end of the horizontal plate portion of two mounting brackets. A forward and reverse motor is mounted on one end of one mounting bracket. The output end of the forward and reverse motor is coaxially and fixedly connected to one end of the worm. A worm wheel meshes with the outer wall of the spiral portion of the worm.

[0008] By adopting the above technical solution, the design of this anti-reverse rotation mechanism can ensure that the clamping plate will not loosen after clamping the aluminum product, thereby achieving the purpose of maintaining the clamping force.

[0009] The linkage mechanism includes a rotating plate fixedly connected to the worm gear via a synchronous shaft. Rotating rods are rotatably mounted at both ends of the rotating plate, and connecting arms are rotatably mounted on the outer wall of the rotating rods. One end of the connecting arm is rotatably connected to the sliding rod.

[0010] By adopting the above technical solution, the rotating worm gear drives the rotating plate connected to it to rotate. The two ends of the rotating plate simultaneously pull the two connecting arms through the rotating rod. At this time, the end of the connecting arm that is rotatingly connected to the rotating plate moves in a circle, while the other end of the connecting arm moves axially along the sliding groove. The other end of the connecting arm drives the sliding rod connected to it to move axially along the sliding groove.

[0011] A cushioning rubber plate is fixedly connected to the side of the two clamps that are close to each other by adhesive.

[0012] By adopting the above technical solution, the design of the buffer rubber plate can avoid the direct hard compression of aluminum products by the clamping plate.

[0013] The workbench has a central shaft integrally formed at the bottom center, protruding downwards. A rotating sleeve is rotatably mounted on the outer periphery of the central shaft via a bearing. The rotating sleeve is integrally formed at the top center of the rotating plate.

[0014] By adopting the above technical solution, when the rotating plate rotates, the rotating plate drives the rotating sleeve to rotate on the outer wall of the central shaft, at which time the central shaft serves to provide rotational support.

[0015] The beneficial effects of this utility model of a limiting fixture for drilling and chamfering aluminum products are:

[0016] By setting up an anti-reverse rotation mechanism and a linkage mechanism, the two clamping plates can be driven to move synchronously. After the clamping plates effectively clamp the aluminum product, the clamping force can be prevented from being unable to be effectively maintained, thus ensuring the clamping effect.

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0022] Reference Figure 1-3 A limiting fixture for drilling and chamfering aluminum products includes a worktable 1. The bottom corners of the worktable 1 are fixedly equipped with downward protruding support legs 3. The top of the worktable 1 is slidably connected to two clamping plates 4. The bottom of the worktable 1 is equipped with an anti-reverse rotation mechanism. The output end of the anti-reverse rotation mechanism is connected to a linkage mechanism. The linkage mechanism is connected to the clamping plates 4. The bottom ends of the clamping plates 4 are integrally formed with downward protruding sliding rods 11. The inside of the worktable 1 is provided with a sliding groove 2 for the sliding rods 11 to slide axially.

[0023] First, place the aluminum product on the top of the workbench 1. Then, activate the anti-reverse rotation mechanism. The anti-reverse rotation mechanism drives the linkage mechanism to move. The linkage mechanism moves the two clamping plates 4 in opposite directions. The clamping plates 4 moving in opposite directions drive the sliding rod 11 to move in the sliding groove 2, realizing the axial movement of the clamping plates 4. The clamping plates 4 moving in opposite directions can clamp the aluminum product. After the aluminum product is clamped, operations such as chamfering and drilling can be performed on the aluminum product.

[0024] The anti-reverse rotation mechanism includes a mounting bracket 5 fixedly connected to the bottom of the workbench 1. A worm gear 10 is rotatably mounted on the inner side of one end of the horizontal plate portion of the two mounting brackets 5. A forward and reverse motor 15 is mounted on one end of one mounting bracket 5. The output end of the forward and reverse motor 15 is coaxially and fixedly connected to one end of the worm gear 10. A worm wheel 9 meshes with the outer wall of the spiral portion of the worm gear 10.

[0025] By starting the forward and reverse motor 15, the forward and reverse motor 15 drives the worm gear 10 connected to its output end to rotate. When the worm gear 10 rotates, its external spiral part squeezes the teeth of the worm wheel 9. At this time, the worm wheel 9 rotates on its own axis. The rotating worm wheel 9 can drive the linkage mechanism to move. This anti-reverse rotation mechanism design can ensure that the clamping plate 4 will not loosen after clamping the aluminum product, thereby achieving the purpose of maintaining the clamping force.

[0026] The linkage mechanism includes a rotating plate 8 fixedly connected to the worm gear 9 via a synchronous shaft. Rotating rods 12 are rotatably mounted at both ends of the rotating plate 8. A connecting arm 14 is rotatably mounted on the outer wall of the rotating rod 12. One end of the connecting arm 14 is rotatably connected to the sliding rod 11.

[0027] The rotating worm gear 9 drives the rotating plate 8 connected to it to rotate. The two ends of the rotating plate 8 simultaneously pull the two connecting arms 14 through the rotating rod 12. At this time, the end of the connecting arm 14 that is connected to the rotating plate 8 rotates in a circle, while the other end of the connecting arm 14 moves axially along the sliding groove 2. The other end of the connecting arm 14 pulls the sliding rod 11 connected to it to move axially along the sliding groove 2.

[0028] Two clamping plates 4 are fixedly connected to each other with a cushioning rubber plate 13 by adhesive glue on their close sides.

[0029] The design of the buffer rubber plate 13 can avoid the problem of pressure damage caused by the clamping plate 4 directly and rigidly squeezing the aluminum product, thus ensuring the quality of the product.

[0030] The bottom center of the workbench 1 has an integrally formed downward protruding central shaft 6. The outer periphery of the central shaft 6 is rotatably mounted with a rotating sleeve 7 via a bearing. The rotating sleeve 7 is integrally formed at the top center of the rotating plate 8.

[0031] When the rotating plate 8 rotates, the rotating plate 8 drives the rotating sleeve 7 to rotate on the outer wall of the central shaft 6. At this time, the central shaft 6 serves to provide rotational support.

[0032] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
