Technical Field

[0001] This utility model relates to the field of automotive duct technology, and in particular to a positioning tool for cutting automotive ducts. Background Technology

[0002] Automotive air ducts are key components of automotive thermal management and air circulation systems, used to achieve functions such as directional airflow, temperature stratification control, and stable airflow pressure. Air conditioning ducts are pipes that transport air in automotive air conditioning systems, used to achieve functions such as the delivery of hot and cold air and internal and external circulation. They are composed of multiple sections of duct spliced ​​together, usually connected by snap-fit. The shape of automotive air ducts varies from vehicle to vehicle, and most automotive air ducts are irregularly shaped. Therefore, after the automotive air duct is manufactured, the excess parts on the surface or at both ends need to be cut off. The irregular shape of the automotive air duct makes it inconvenient to clamp with existing clamps and makes it impossible to fix it at multiple points. Utility Model Content

[0003] The purpose of this utility model is to address the aforementioned problems and shortcomings by proposing a positioning fixture for cutting automotive air ducts.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A positioning fixture for cutting automotive air ducts includes a fixing block. A positioning groove is formed at the center of the top outer wall of the fixing block, and pop-out grooves are formed at equal intervals on the inner walls of both sides of the fixing block located at the positioning groove. A pull hole is formed at the center of the other end of the pop-out groove of the fixing block, and a fixing structure is formed on the outer walls of both sides of the fixing block at the pull hole. The fixing structure includes a bearing seat 1 installed at both ends of one outer wall of the fixing block, a take-up shaft installed on the inner outer wall of the bearing seat 1, a take-up groove formed on the outer wall of the take-up shaft at the pull hole, and a fixing hole formed on the outer wall of the take-up shaft at the center of the take-up groove.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Example 1: Reference Figs. 1-3 As shown, a positioning fixture for cutting automotive air ducts includes a fixing block 1. A positioning groove 2 is provided at the center of the top outer wall of the fixing block 1, and pop-out grooves 4 are provided at equal intervals on the inner walls of both sides of the fixing block 1 located in the positioning groove 2. A pulling hole 5 is provided at the center of the other end of the fixing block 1 located in the pop-out groove 4, and a fixing structure 7 is provided on the outer walls of both sides of the fixing block 1 located at the pulling hole 5. The fixing block 1 is slidably connected to the inner wall of the pop-out groove 4 with a pop-out clamping plate 6. A groove is provided at one end of the pop-out clamping plate 6. Supporting springs 9 are installed at both ends of the pop-out clamping plate 6 in the groove. The outer wall of the other end of the supporting spring 9 is installed on the inner wall of one end of the pop-out groove 4. An anti-slip pad 15 is adhered to one side of the outer wall of the pop-out clamping plate 6. The fixing block 1 has cleaning ports 3 at both ends located at the bottom of the positioning groove 2, and fixing plates 8 are welded to the bottom outer walls on both sides of the fixing block 1. The supporting force of the spring 9 in the pop-out slot 4, combined with the extension of the pop-out clamp 6, fixes the air duct in the positioning slot 2 of the fixing block 1, which is convenient for fixing, easy to fit the shape of the air duct, and easy to support. Supported by the spring 9, the pop-out clamps 6 at both ends contact the outer wall of the air duct through the anti-slip pads 15, clamping the outer wall of the car air duct at multiple points. The outer wall of the pop-out clamps 6 fits against the outer wall of the air duct, making it easy to clamp irregularly shaped air ducts.

[0015] Example 2: Reference Figs. 1-3 As shown, the fixing structure 7 includes bearing seats 10 installed at both ends of the outer wall of one side of the fixing block 1, a take-up shaft 11 installed on the inner outer wall of the bearing seat 10, a take-up groove 12 opened on the outer wall of the take-up shaft 11 at the pull hole 5, and a fixing hole 13 opened on the outer wall of the take-up shaft 11 at the center of the take-up groove 12. The winding shaft 11 is connected to the winding rope 14 at the fixing hole 13, and the other end of the winding rope 14 is installed at the center of the inner wall of the ejection clamp 6. The outer wall of the winding rope 14 is slidably connected to the inner wall of the pulling hole 5. Bearing seats 17 are installed at both corners of the outer wall of one side of the fixed block 1, and worm gears 18 are installed on the inner outer wall of the bearing seats 17. Square blocks are welded to the outer wall of the top of the worm gears 18. A worm wheel 16 is installed on the outer wall of one end of the winding shaft 11 at the worm 18, and the worm 18 meshes with the worm wheel 16; One end of the winding rope 14 is fixedly connected to the winding groove 12 of the winding shaft 11 through the fixing hole 13 on the winding shaft 11, which facilitates fixing one end of the winding rope 14.

[0016] Working principle: In the initial state, the pop-out clamps 6 are in contact with each other at one end under the action of the support spring 9. When in use, one end of the crank is inserted into the square protrusion to drive the worm gear 18 to rotate. The worm gear 18 meshes with the worm wheel 16 to drive the winding shaft 11 to rotate. After the winding shaft 11 rotates, it winds the winding rope 14 at the winding groove 12 through the fixing hole 13. The winding rope 14 pulls the pop-out clamps 6 to compress the support spring 9, so that the pop-out clamps 6 slide in the pop-out groove 4 and enter the pop-out groove 4. Place one end of the car air duct to be processed in the positioning groove 2 of the fixing block 1. Rotate the worm gear 18 in the opposite direction to unwind the winding rope 14 through the winding shaft 11. At this time, the support spring 9 is unrestrained and the support pop-out clamps 6 extend out of the pop-out groove 4. Under the support of the support spring 9, the two ends of the pop-out clamps 6 contact the outer wall of the air duct through the anti-slip pads 15, clamping the outer wall of the car air duct at multiple points. The outer wall of the pop-out clamps 6 is in contact with the outer wall of the air duct, which is convenient for clamping irregularly shaped air ducts.
