[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figure 1-2 As shown:
[0025] A T-bar press-fitting device includes a welding frame 1, a C-shaped frame 8 fixedly mounted on the welding frame 1, and a tooling seat 3 fixedly mounted at the bottom end of the C-shaped frame 8 for supporting and fixing the T-bar and pinion shaft.
[0026] The top of the C-frame 8 is equipped with a servo press 2 corresponding to the tooling base 3. The servo press 2 is used to perform the T-Bar crimping operation.
[0027] A barcode scanner 7 for scanning T-bar is installed on the front end face of the welding frame 1;
[0028] An electrical control cabinet 9 is fixedly installed on one side of the welding frame 1. The electrical control cabinet 9 contains electrical and electronic components that control the entire device.
[0029] The welding frame 1 is equipped with a replaceable change tool 11, which is used for crimping operations of different models of T-Bar and Pinion shafts.
[0030] The bottom of the welding frame 1 is fixedly equipped with an NG material box 10 for collecting defective products;
[0031] The C-frame 8 is equipped with a photoelectric sensor and a laser micrometer.
[0032] A human-machine interface 5 is fixedly installed on one side of the welding frame 1. The human-machine interface 5 is connected to the electrical control cabinet 9 and is used for operator control and monitoring of the equipment.
[0033] A three-color alarm light 4 is fixedly installed on the top of the welding frame 1. The three-color alarm light 4 is connected to the electrical control cabinet 9 and is used to indicate the equipment status.
[0034] Two sets of safety light curtains 6 are fixedly installed on one side of the welding frame 1 in a symmetrical arrangement. The safety light curtains 6 are used to detect the safety of the operators.
[0035] The tooling base 3 is equipped with a positioning mechanism to ensure the correct alignment and positioning of the T-Bar and Pinion axis;
[0036] The servo press 2 is equipped with a pressure sensor to monitor the pressure during the pressing process.
[0037] In this implementation plan: When using the T-bar pressing device, the Pinion Shaft and T-Bar are respectively fed by the material rack box. The Pinion Shaft is traced individually to prevent errors by barcode scanner 7, and the T-Bar is traced in batches to prevent errors by barcode scanner 7. The preset number of scanned items is 200 pieces. The scanned Pinion Shaft and T-Bar are manually pre-installed into the tooling seat 3. The positioning mechanism on the tooling seat 3 can ensure the correct alignment and positioning of the T-Bar and Pinion Shaft.
[0038] After pre-assembly, the through-beam photoelectric sensor emits and receives light beams to check whether the T-Bar and Pinion axis are in the correct tooling position. When the parts are correctly placed, the photoelectric signal will be triggered, allowing the pressing process to continue. The laser micrometer accurately measures the size of the T-Bar by emitting laser and measuring the time interval of the reflected light, thus preventing material mixing errors.
[0039] Then, the servo press 2 is started and lowered to the predetermined position. The laser micrometer performs diameter detection to ensure that the T-Bar size is correct. The tooling seat 3 presses according to the set force mode until the preset force value is reached and then stops to ensure the pressing quality and press the T-Bar into the Pinion shaft.
[0040] During the pressing process of tooling seat 3, the pressure sensor installed on tooling seat 3 can detect the pressing force in real time to ensure that it meets the process requirements;
[0041] After pressing is completed, the finished product is inspected. If the product is qualified, the operator takes it out and places it in the buffer position. If the product is unqualified, the operator takes it out and puts it into the NG material box 10. The tooling that can be replaced by the tooling changer 11 is used for pressing operations of different models of T-Bar and Pinion shaft.
[0042] Through this operation, the T-bar pressing device can effectively avoid the mixing of materials and prevent the traceability of problematic products from becoming difficult during use, thus improving quality control. Moreover, the positioning of the product in the tooling is more accurate, preventing incomplete or excessive pressing and improving processing quality. The device is more effective and meets actual usage requirements.
[0043] The tooling changeover principle of the T-Bar crimping device achieves fast, accurate, and safe tooling changeover by employing axial positioning and mechanical locking, combined with a proximity switch error-proofing system. This design not only reduces changeover time but also lowers the risk of operational errors through the error-proofing system, thereby improving the reliability and efficiency of the entire production process.
[0044] The working principle and usage process of this utility model are as follows: In use, the Pinion Shaft and T-Bar are supplied by the material rack and hopper respectively. The Pinion Shaft is traced individually using a barcode scanner 7 to prevent errors, while the T-Bar is traced in batches using the same barcode scanner 7. The preset number of scanned items is 200 pieces. The scanned Pinion Shaft and T-Bar are manually placed into the fixture 3. The positioning mechanism on the fixture 3 ensures the correct alignment and positioning of the T-Bar and Pinion Shaft. After pre-assembly, a photoelectric sensor emits and receives light beams to check if the T-Bar and Pinion Shaft are in the correct fixture position. The photoelectric signal is triggered only when the parts are correctly placed, allowing the pressing process to continue. A laser micrometer accurately measures the size of the T-Bar by emitting a laser and measuring the time interval between reflected light, preventing material mixing errors. Subsequently, the servo press 2 is started and lowered to the predetermined position. The laser micrometer then performs diameter detection to ensure the T-Bar is correctly aligned. - The bar size is correct. The tooling holder 3 presses the bar according to the set force mode until the preset force value is reached, and then stops to ensure the pressing quality. The T-bar is pressed into the pinion shaft. During the pressing process, the pressure sensor set in the tooling holder 3 can detect the pressing force in real time to ensure that it meets the process requirements. After pressing, the finished product is inspected. If the product is qualified, the operator takes it out and places it in the buffer position. If the product is unqualified, the operator takes it out and puts it into the NG material box 10. The tooling that can be replaced by the tooling changer 11 is used for pressing operations of different models of T-bar and pinion shaft.
