Description

Technical Field

[0001] The utility model relates to the technical field of flange processing, in particular to a fixture for automatically clamping flange processing. Background Art

[0002] During flange machining, fixtures are used to secure the workpiece and ensure stability and precision during machining. The following are some of the main functions of fixtures in flange machining: Positioning the workpiece: A fixture accurately places the workpiece in the machining position, ensuring the accuracy of the machining position and direction. This helps ensure that the final flange has the correct size and shape. Securing the workpiece: The main purpose of a fixture is to firmly secure the workpiece to prevent it from moving or shaking during machining. This helps improve machining accuracy and stability, ensuring consistent machining results. Improving productivity: The use of fixtures can effectively improve productivity. By securing the workpiece in position, the operator can focus more on the machining operation, reducing adjustments and repositioning of the workpiece, thereby saving time and improving productivity. Protecting the workpiece surface: Fixtures typically have appropriate padding or protective pads to prevent damage or scratches on the workpiece surface. This is particularly important when machining demanding workpieces, as it helps maintain the surface quality of the workpiece.

[0003] When using a fixture to process flanges, manual opening and closing of the clamp is often required, which can easily affect the efficiency of flange processing. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1-4The utility model provides an embodiment: an automatically clamping flange processing fixture, including a clamping base 1, an output motor 12 is fixedly provided on one side of the inner part of the clamping base 1, a long threaded rod 4 is fixedly provided on the output end of the output motor 12, both sides of the long threaded rod 4 are threadedly sleeved with internal threaded sleeves 14, and a number one bevel gear 15 is fixedly sleeved in the middle of the long threaded rod 4.

[0032] Among them, the upper ends of the two internal threaded sleeves 14 are fixed with extension rods 3, and limited long holes 11 are provided at the centers of both sides of the upper end surface of the clamping base 1. A protruding section 5 is provided at the center of the upper end surface of the clamping base 1, and a plate groove 2 is provided at the center of the upper end surface of the protruding section 5. A placement plate 8 is hingedly provided at the front end inside the plate groove 2, and a photosensitive sensor 7 is embedded at the front end of the upper end surface of the placement plate 8. Electromagnets 9 are embedded at both sides of the upper end surface of the protruding section 5. The photosensitive sensor 7, electromagnet 9 and output motor 12 are externally connected to the control system, and an external power supply or a built-in battery are used to supply energy and control the opening and closing of the equipment, and at the same time to control the forward and reverse rotation of the output motor 12.

[0033] The upper ends of the two extension rods 3 pass through the limiting long holes 11 and are connected to the upper end of the clamping base 1, where a clamping block 10 is fixed. A clamping groove 6 is provided at the center of the opposite side of the two clamping blocks 10. An internal threaded tube 18 is rotatably provided at the center of the inner top surface of the clamping base 1. A No. 2 bevel gear 16 is fixed at the lower end of the internal threaded tube 18. A short threaded rod 17 is threadedly sleeved on the upper end of the internal threaded tube 18. When in use, this device can achieve double clamping and fixation, and in this process can be detected by the photosensitive sensor 7 to achieve automatic fixed clamping, and after processing is completed, it can also achieve the function of pushing out the flange workpiece. It is simple to operate and easy to use.

[0034] The upper end face of the protruding section 5 is fixedly provided with a stopper at the front end edge on both sides, which plays a positioning role. The No. 1 bevel gear 15 and the No. 2 bevel gear 16 are meshed and connected for transmitting the rotating power. The upper end of the short threaded rod 17 passes through the protruding section 5 to the interior of the plate groove 2, and is hinged to the lower end face of the placement plate 8. The placement plate 8 can be pushed open by the short threaded rod 17 to facilitate the launch of the flange workpiece. The long threaded rod 4 is rotated away from the output motor 12 and is set on the inner wall of one side of the clamping base 1 to increase the stability of the long threaded rod 4, and the threads at both ends of the long threaded rod 4 are opposite. Support blocks 13 are fixedly provided at the four corners of the lower end face of the clamping base 1. The support blocks 13 are used to support and increase stability. The internal threaded tube 18 is fixedly set inside the protruding section 5 through the axial side. The internal threaded tube 18 is used to control the extension and retraction of the short threaded rod 17.

[0035] Working principle: When in use, place the flange to be processed on the placement plate 8 and push the flange forward. When the flange is blocked by the block, the photosensitive sensor 7 will detect the flange and start the electromagnet 9 and the output motor 12 at the same time. The output end of the output motor 12 rotates to drive the long threaded rod 4 to rotate. The rotation of the long threaded rod 4 can make the internal threaded sleeves 14 move closer to each other, so that the two clamping blocks 10 move closer to each other and the clamping groove 6 fixes the flange. In this process, the rotation of the long threaded rod 4 can drive the first bevel gear 1 5. The rotation of the No. 1 bevel gear 15 drives the No. 2 bevel gear 16 to rotate. The rotation of the No. 2 bevel gear 16 drives the internal threaded sleeve 14 to rotate. The rotation of the internal threaded sleeve 14 causes the short threaded rod 17 to move downward, so that the placement plate 8 and the protruding section 5 remain parallel, and the flange can be processed. After the processing is completed, the output motor 12 is started, and the long threaded rod 4 is rotated in the opposite direction, so that the clamping block 10 is relatively away. At the same time, the short threaded rod 17 pushes the placement plate 8 upward, and the electromagnet 9 is turned off at the same time. The placement plate 8 on the inclined surface realizes the sliding of the flange, and there is no need to manually take the flange.

[0036] 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.
