Description

Technical Field

[0001] This utility model relates to the field of automotive bushing processing technology, specifically a positioning fixture for automotive bushing processing. Background Technology

[0002] Bushings, typically installed on shafts, primarily serve to protect the shaft and support rotating components. They reduce friction between the shaft and stationary parts, thereby extending the shaft's lifespan. In some cases, bushings can also be used to adjust the shaft's length or repair worn shafts.

[0003] When machining automotive axle bushings, chamfering is required on both sides. Typically, a feeding mechanism feeds the axle bushing to a positioning fixture, and a cylinder pushes the axle bushing, which is then clamped between two semi-circular clamping plates. Motors on both sides start to chamfer the two ends of the axle bushing. However, some automotive axle bushings have different outer diameters at different locations, and the semi-circular clamping plates can only clamp axle bushings of the same diameter, resulting in low applicability. Therefore, we propose a positioning fixture for machining automotive axle bushings. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a positioning fixture for machining automotive bushings. By using a fixed clamping seat and an adjustable movable clamping seat, it can center and clamp automotive bushings with different outer diameters at different positions, which can effectively solve the problems in the background art.

The lead screw of the movable positioning seat is rotatably connected to the rear end of the adjacent movable V-shaped seat, and the lead screw of the fixed positioning seat is rotatably connected to the front end of the fixed V-shaped seat. Hexagonal columns are fixedly connected to the opposite outer ends of the two lead screws to adjust the relative distance between the movable V-shaped seat and the fixed V-shaped seat.

[0010] Furthermore, the positioning mechanism also includes anti-slip rubber pads. The inclined surfaces of the movable V-groove, fixed V-plate, movable V-seat, and fixed V-seat are all fixedly connected with anti-slip rubber pads, which provide cushioning and protection while preventing slippage.

A fixed V-plate 44 is provided at the rear end of the fixed positioning seat 42. An adjustable fixed V-seat 46 is provided on the left side of the fixed positioning seat 42. The fixed V-plate 44 and the movable V-groove 43 are aligned front to back, and the movable V-seat 45 and the fixed V-seat 46 are aligned front to back. Positioning mechanism 4 also includes a sliding column 48 and a lead screw 49. The left ends of the movable positioning seat 41 and the left ends of the fixed positioning seat 42 are both fixedly connected to the corresponding inner surfaces of evenly distributed sliding columns 48. A movable V-shaped seat 45 is slidably connected between the sliding columns 48 of the movable positioning seat 41, and a fixed V-shaped plate 44 is slidably connected between the sliding columns 48 of the fixed positioning seat 42. The left ends of the movable positioning seat 41 and the left ends of the fixed positioning seat 42 are both threadedly connected to lead screws 49. The lead screw 49 of the movable positioning seat 41 is rotatably connected to the rear end of the adjacent movable V-shaped seat 45, and the lead screw 49 of the fixed positioning seat 42 is rotatably connected to the front end of the fixed V-shaped seat 46. Hexagonal columns are fixedly connected to the opposite outer ends of the two lead screws 49. The positioning mechanism 4 also includes anti-slip rubber pads 47. Anti-slip rubber pads 47 are fixedly connected to the inclined surfaces of the groove 43, fixed V-plate 44, movable V-seat 45, and fixed V-seat 46. A fixed plate 8 is fixedly connected to the left side of the movable V-groove 43, and an electromagnet 9 is fixedly connected to the front side of the fixed plate 8. The input end of the electromagnet 9 is electrically connected to the output end of the microcontroller 7. A bracket 3 is set on the rear side of bracket 1. A cylinder 6 is fixedly connected to the upper end of bracket 3. The telescopic end of the cylinder 6 is fixedly connected to the rear end of the movable positioning seat 41. The air inlet of the cylinder 6 is connected to the air outlet of an external air pump. By adjusting the distance between the movable V-seat 45 and the fixed V-seat 46, the automobile bushing is held and fixed by the movable V-groove 43 and the fixed V-plate 44. By rotating the hexagonal column at the rear end, the lead screw 49 at the rear end rotates. The moving V-shaped seat 45 slides forward between the four sliding pillars 48. The anti-slip rubber pad 47 of the moving V-shaped seat 45 adheres to the front end of the car axle sleeve. The feeding mechanism pushes the neatly arranged car axle sleeves into the bracket 1 from the right side. The smaller outer diameter end of each car axle sleeve faces left. The front end of the car axle sleeve contacts the baffle 51, indicating that the car axle sleeve has been successfully pushed into the bracket 1. The electromagnet 9 is activated, and the telescopic end of the cylinder 6 pushes the moving positioning seat 41 forward. The electromagnet 9 magnetically attracts the car axle sleeve, which is then attracted into the moving V-groove 43. The moving positioning seat 41 pushes the car axle sleeve forward until the fixed V-plate 44 is inserted into the moving V-groove 43. The rear end of the car axle sleeve is clamped between the fixed V-plate 44 and the moving V-groove 43.Simultaneously, the fixed V-shaped seat 46 is inserted into the interior of the movable V-shaped seat 45, and the front end of the automotive bushing is clamped between the fixed V-shaped seat 46 and the movable V-shaped seat 45. The anti-slip rubber pad 47 prevents the automotive bushing from slipping while providing cushioning.

[0024] It also includes a microcontroller 7, which is located on the left side of bracket 1, and the input terminal of the microcontroller 7 is electrically connected to an external power supply.

[0025] The system also includes a limiting mechanism 5, which comprises a baffle 51, a knob 52, a sliding column 53, and a lead screw 54. The rear side of the baffle 51 is fixedly connected to evenly distributed sliding columns 53, which are slidably connected to the inside of the sliding holes at the left end of the bracket 1. The rear side of the baffle 51 is rotatably connected to the lead screw 54, which is threaded to the left end of the bracket 1. The left end of the lead screw 54 is fixedly fitted with a knob 52, which is located at the left end of the bracket 1. When the knob 52 is rotated, the lead screw 54 rotates, causing the baffle 51 to slide to the right until it contacts the front end of the car axle sleeve. The contact of the front end of the car axle sleeve with the baffle 51 indicates that the car axle sleeve has been pushed into the interior of the bracket 1.

[0026] The working principle of the positioning fixture for processing automotive axle sleeves provided by this utility model is as follows: Adjusting the distance between the movable V-shaped seat 45 and the fixed V-shaped seat 46, the automotive axle sleeve is held and fixed by the movable V-groove 43 and the fixed V-plate 44. Rotating the hexagonal column at the rear end causes the lead screw 49 at the rear end to rotate, driving the movable V-shaped seat 45 to slide forward between the four sliding columns 48. The anti-slip rubber pad 47 of the movable V-shaped seat 45 adheres to the front end of the automotive axle sleeve. Similarly, adjusting the fixed V-shaped seat 46 achieves the clamping adjustment of the automotive axle sleeve, aligning the rear end of the automotive axle sleeve with the right inner wall of the bracket 1. Rotating the knob 52 causes the lead screw 54 to rotate, driving the baffle 51 to slide to the right until it adheres to the front end of the automotive axle sleeve, completing the adjustment. The feeding mechanism pushes the neatly arranged automotive axle sleeves into the bracket 1 from the right side. The smaller outer diameter end faces left. The front end of the car bushing contacts the baffle 51, indicating that the car bushing has been pushed into the bracket 1. The electromagnet 9 is activated, and the telescopic end of the cylinder 6 pushes the movable positioning seat 41 forward. The electromagnet 9 magnetically attracts the car bushing, and the car bushing is attracted into the movable V-groove 43. The car bushing is pushed forward by the movable positioning seat 41 until the fixed V-plate 44 is inserted into the movable V-groove 43. The rear end of the car bushing is clamped between the fixed V-plate 44 and the movable V-groove 43. At the same time, the fixed V-seat 46 is inserted into the movable V-seat 45. The front end of the car bushing is clamped between the fixed V-seat 46 and the movable V-seat 45. The anti-slip rubber pad 47 prevents the car bushing from slipping while providing cushioning. The electromagnet 9 prevents the car bushing from slipping after it comes off the baffle 51.

[0027] It is worth noting that the microcontroller 7 disclosed in the above embodiments can be AT32F4212C8T7, the electromagnet 9 can be DS-ET1212-01 electromagnet, and the microcontroller 7 controls the operation of the electromagnet 9 and the external air pump using methods commonly used in the prior art.
