Technical Field
[0001] This utility model relates to a clamp, and more particularly to a clamp for slotting T-shaped thread cutters. Background Technology
[0002] A T-type thread cutter is a turning tool used to machine T-shaped threads, primarily for transmission and fastening large parts. This thread cutter needs to be positioned at a specific angle during grooving. On automated grinding machines, because the robotic arm's loading and unloading is vertical, the fixture for this cutting tool in automated machining needs to be able to switch angles while ensuring the accuracy and stability of the cutting tool. Therefore, a new type of T-type thread cutter grooving fixture with high precision, good stability, and high versatility is required. Utility Model Content
[0003] The purpose of this utility model is to provide a fixture for slotting T-shaped thread cutters to solve the above-mentioned technical problems.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A fixture for slotting T-shaped thread cutters includes a fixture base, a fixture support frame, a swing angle limiter, a swing angle cylinder, a product positioning block mounting base, a swing angle rotating pin, a product positioning block, a product pressure plate, a pressure plate mounting base, a product clamping cylinder mounting base, a pressure plate mounting base rotating pin, and a product clamping cylinder. The fixture support frame is screw-fixed to the top center of the fixture base. The swing angle limiter is installed on the rear side of the top of the fixture support frame and locked in place by its own threads and a nut. The swing angle cylinder is screw-fixed to the bottom rear end of the fixture support frame and below the rear end of the swing angle limiter. The clamp support frame has a product positioning block mounting seat installed on the inner side of its front end and is hinged to the top of both sides by a swing angle rotating pin. The top of the front end of the product positioning block mounting seat has a product positioning block fixed by screws. The product is placed in the middle of the top of the product positioning block. A product pressure plate is installed at the front end of the product and is fixed to the top of the pressure plate mounting seat by screws. A product pressing cylinder mounting seat is installed at the bottom of the front end of the pressure plate mounting seat and is hinged to it by a rotating pin of the pressure plate mounting seat. A product pressing cylinder is fixed to the bottom of the inner side of the product pressing cylinder mounting seat by screws.
[0006] Based on the above technical solution, the pressure plate mounting base includes a reset spring, a cylindrical groove, a roller mounting groove, and a roller. The reset spring is connected to the top of the rear end of the pressure plate mounting base. The reset spring is installed in the cylindrical groove at the top of the front end of the product positioning block mounting base. A roller mounting groove is opened in the middle of the bottom end of the pressure plate mounting base. A hinged roller is installed inside the roller mounting groove.
[0007] Based on the above technical solution, a welded and fixed connecting block is installed at the top center of the product pressing cylinder. The connecting block is inserted and connected to the connecting groove at the bottom of the upper clamping force-bearing inclined block by screws. The clamping force-bearing inclined block has grooves on the left and right sides. The grooves are inserted and connected to the bosses on both sides and can move in the vertical direction. The bosses are fixed to the rear end surface of the product pressing cylinder mounting base by screws.
[0008] Compared with existing technologies, this utility model has the following advantages: The clamping blade of this utility model adopts a vertical clamping method, with the top of the blade being the machining surface. The grinding machine performs grooving on the top using a grinding wheel. The blade positioning method uses a V-shaped positioning block, which has extremely high positioning accuracy. The clamping design includes a product clamping cylinder and an angle switching cylinder, which can automatically clamp the product and switch the angle on an automated grinding machine. The product clamping structure adopts the principle of a force-saving lever plus a wedge clamping mechanism, which greatly increases the clamping force on the product and reduces the space occupied by the clamping fixture.
[0009] The angle switching mechanism uses the principle of force-saving levers to increase the stability of the mechanism after the swing angle. During processing, the clamp will not shift under force. The positioning block and pressure plate of the cutting tool both have positioning surfaces and are fixed with two screws, which makes them easy to disassemble. When changing product models, only the positioning block and pressure plate need to be replaced, making it highly versatile. Attached Figure Description

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0015] like Figure 1-3As shown, a fixture for slotting T-shaped thread cutters includes a fixture base 1, a fixture support frame 2, a swing angle limiter 3, a swing angle cylinder 4, a product positioning block mounting base 5, a swing angle rotating pin 6, a product positioning block 7, a product 8, a product pressure plate 9, a pressure plate mounting base 10, a product clamping cylinder mounting base 11, a pressure plate mounting base rotating pin 12, and a product clamping cylinder 13. The fixture support frame 2, fixed with screws, is installed at the top center of the fixture base 1. The swing angle limiter 3 is installed at the rear top of the fixture support frame 2 and locked in place by its own threads and a nut. The swing angle cylinder 4, fixed with screws, is installed at the bottom rear end of the fixture support frame 2 and below the rear end of the swing angle limiter 3. The clamp support frame 2 has a product positioning block mounting seat 5 installed on the inner side of its front end and is hinged to it by the swing angle rotating pins 6 at the top of both sides. The product positioning block mounting seat 5 has a product positioning block 7 fixed by screws installed on the top of its front end. The product 8 is placed in the middle of the top of the product positioning block 7. The product pressure plate 9 is installed on the front end of the product 8. The product pressure plate 9 is fixed to the top of the pressure plate mounting seat 10 by screws. The pressure plate mounting seat 10 has a product pressing cylinder mounting seat 11 installed on the bottom of its front end and is hinged to it by the pressure plate mounting seat rotating pin 12. The product pressing cylinder 13 is fixed by screws installed on the bottom of the inner side of the product pressing cylinder mounting seat 11.
[0016] The pressure plate mounting base 10 includes a return spring 14, a cylindrical groove 15, a roller mounting groove 16, and a roller 17. The return spring 14 is connected to the top of the rear end of the pressure plate mounting base 10. The return spring 14 is installed in the cylindrical groove 15 at the top of the front end of the product positioning block mounting base 5. The roller mounting groove 16 is opened in the middle of the bottom end of the pressure plate mounting base 10. The roller 17 is hingedly connected and installed inside the roller mounting groove 16.
[0017] A welded connecting block 18 is installed at the top center of the product clamping cylinder 13. The connecting block 18 is inserted into the connecting groove 20 at the bottom of the upper clamping force-bearing inclined block 19 and fixed with screws. The clamping force-bearing inclined block 19 has grooves 21 on the left and right sides. The grooves 21 are inserted into the bosses 22 on both sides and can move in the vertical direction. The bosses 22 are fixed to both sides of the rear end surface of the product clamping cylinder mounting base 11 with screws.
[0018] The working principle of this utility model is as follows: First, when the telescopic rod of the product clamping cylinder extends, it drives the clamping force-bearing inclined block to move forward. Then, the roller contacts the inclined surface of the clamping force-bearing inclined block. At the same time, the product clamping cylinder mounting seat rotates around the rotating pin of the pressure plate mounting seat as the rotation center, thereby pressing the product with the product pressure plate. Then, when the telescopic rod of the product clamping cylinder retracts, the pressure plate reset spring pushes the product pressure plate open, thereby releasing the product. Then, when the telescopic rod of the swing angle cylinder extends, it pushes the product positioning block mounting seat to rotate around the rotating pin of the swing angle as the rotation center, and the swing angle limiter retracts to the hard limit as the limit, thereby causing the product to change angle. Then, when the telescopic rod of the swing angle cylinder retracts, the swing angle limiter rebounds and pushes the product positioning block mounting seat back to its original position, and the product will also return to a relatively vertical state.
[0019] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
