Description

Technical Field

[0001] The utility model relates to the field of mechanical engineering, in particular to an ejection mechanism for mechanical processing. Background Art

[0002] Machining is a manufacturing process that changes the shape, size, and surface quality of a workpiece by removing material. During the machining process, after some products are produced, an ejection structure is used to eject the product from the processing equipment to ensure smooth processing. Some ejection mechanisms are pneumatically driven. Pneumatic ejection mechanisms rely on compressed air as a power source. Compressed air can quickly transmit force, allowing the ejection action to be completed quickly, which can greatly improve production efficiency.

[0003] In the prior art, some pneumatic ejection mechanisms require the installation of air pipes to achieve ventilation during use. These air pipes are usually connected to the cylinder by means of air pipe quick connectors, which are generally fixed to the cylinder by threads. Some use L-shaped quick connectors for ease of installation. However, after the air pipe quick connector is fixed to the air pipe by threads, if the angle position of one end of the connecting hose is incorrect, it needs to be loosened and then adjusted, which is extremely troublesome. Although the threaded connection can improve the connection stability, the friction between the threads is large. Repeated angle adjustment and thread rotation may cause thread wear, thereby reducing stability. In addition, when the pneumatic ejection mechanism is in operation, the airflow at the air pipe quick connector is large, and vibration may cause the connection end of the air pipe quick connector and the cylinder to rotate and loosen, resulting in low stability. Therefore, a ejection mechanism for machining is proposed to solve the above problems. Utility Model Content

[0031] Reference Figure 1 - Figure 2 、 Figure 4 The anti-loosening component also includes a support plate 52, which is rotatably connected to the connecting plate 51 to ensure that the clamping block 54 can smoothly fix the quick connector 2.

The upper surface of the support plate 52 is fixedly connected to a rectangular shell 53 to ensure the stable sliding of the clamping block 54. The front surface of the rectangular shell 53 is rotatably connected with a bidirectional threaded rod 55. The bidirectional threaded rod 55 is a prior art. It is a rod-shaped structure with two groups of threads with different rotation directions on the outer wall. When rotating, the structure threaded connected to its outer wall will move linearly in relative or opposite directions. At the same time, it has the characteristics of front and rear self-locking, ensuring the stability of the structure threaded connected to its outer wall. The outer wall of the bidirectional threaded rod 55 is threadedly connected with a clamping block 54. The rear surface of the clamping block 54 in contact with the quick connector 2 is made of rubber to ensure the stability of the clamping. The rear surface of the clamping block 54 contacts the front surface of the right end of the quick connector 2. The front surface of the bidirectional threaded rod 55 is provided with a hexagonal groove 56. Workers can use tools to insert the inner wall of the hexagonal groove 56 to rotate the bidirectional threaded rod 55.

[0032] Reference Figure 2 - Figure 4The upper surface of the threaded sleeve 41 is fixedly connected with a sealing ring 2 44, which is made of rubber, and its inner wall fits tightly with the outer wall of the bottom end of the quick connector 2 to ensure the sealing effect. The outer wall of the sealing ring 2 44 slides on the inner wall of the left end of the connecting plate 51, and the inner wall of the sealing ring 2 44 contacts the outer wall of the left bottom end of the quick connector 2. The front surface of the bottom end of the threaded sleeve 41 is slidably connected with a pull rod 42 for limiting the threaded sleeve 41 and the ring 57. A through hole 7 is provided on the outer wall of the bottom end of the connecting pipe 3. The outer wall of the rear end of the pull rod 42 contacts the inner wall of the through hole 7. A spring 46 is sleeved on the outer wall of the pull rod 42. The spring 46 always pulls the pull rod 42 backward through its own elasticity to ensure the stability of its limit. One end of the spring 46 is fixedly connected to the front surface of the bottom end of the threaded sleeve 41, and the other end of the spring 46 is fixedly connected to the rear surface of the pull rod 42.

[0033] Reference Figure 2 、 Figure 4 The anti-loosening component includes a ring 57 that ensures the stable rotation of the connecting plate 51. The ring 57 is fixedly connected to the lower surface of the left end of the connecting plate 51. A slide groove 45 is provided on the upper surface of the threaded sleeve 41. The ring 57 is slidably connected to the inner wall of the slide groove 45. There are multiple groups of clamping blocks 54. Multiple groups of clamping blocks 54 are provided to ensure the stability of the fixed joint, and the multiple groups of clamping blocks 54 are symmetrically arranged with the center line of the rectangular shell 53 as the axis of symmetry. A limiting hole 58 is provided on the outer wall of the ring 57 to match the pull rod 42, and the pull rod 42 slides on the inner wall of the limiting hole 58.

[0034] Working principle: When this ejection mechanism is in use, the quick connector 2 is threadedly connected to the outer wall of the threaded sleeve 41 to achieve a locked fixation. The inner wall thread at the bottom end of the quick connector 2 is adapted to the outer wall of the threaded sleeve 41 to ensure the stability of the connection. In addition, the sealing ring 1 43 on the threaded sleeve 41 is slidably connected to the inner wall of the sealing groove 6 on the lower surface of the connecting pipe 3. At the same time, the inner wall of the sealing ring 2 44 contacts the outer wall of the left bottom end of the quick connector 2. Double sealing is performed by the sealing ring 1 43 and the sealing ring 2 44 to improve the sealing effect.

[0035] When the angle of the quick connector 2 needs to be adjusted, pull the pull rod 42 so that the outer wall of its rear end moves out of the through hole 7 of the outer wall of the bottom end of the connecting pipe 3, thereby releasing the limit on the threaded sleeve 41. At this time, the threaded sleeve 41 can be rotated to adjust the angle of the quick connector 2. After the adjustment is completed, release the pull rod 42, and the elasticity of the spring 46 causes the pull rod 42 to move backward, re-limiting the threaded sleeve 41.

[0036] In order to prevent the quick connector 2 from rotating and loosening due to vibration, an anti-loosening component is provided. A tool is inserted into the hexagonal groove 56 on the front surface of the bidirectional threaded rod 55, and the bidirectional threaded rod 55 is rotated. When the bidirectional threaded rod 55 rotates, the clamping block 54 threadedly connected to its outer wall undergoes linear movement in relative or opposite directions, so that the rear surface of the clamping block 54 contacts the front surface of the right end of the quick connector 2, clamping and fixing the top end of the quick connector 2. The rear surface of the clamping block 54 in contact with the quick connector 2 is made of rubber to ensure the stability of the clamping.

[0037] At the same time, the lower surface of the connecting plate 51 slides on the upper surface of the threaded sleeve 41, and the ring 57 is fixedly connected to the lower surface of the left end of the connecting plate 51. The ring 57 slides in the slide groove 45 on the upper surface of the threaded sleeve 41, and the angle of the clamping block 54 can be adjusted to ensure that it can smoothly fix the top of the quick connector 2, and the ring 57 is also limited by the pull rod 42, so that the angle of the quick connector 2 and the clamping block 54 can be adjusted together, which improves convenience.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
