Description

Technical Field

[0001] This utility model relates to the technical field of bushing shaping equipment, and in particular to a shaping device for processing composite bushings. Background Technology

[0002] Bushings are produced by machining metal blanks using lathes, milling machines, and other mechanical processing equipment to obtain cylindrical workpieces of the required shape and size. After machining, the surface of the bushing has burrs and other defects, requiring further processing by shaping equipment to improve the bushing's accuracy and durability. However, existing bushing shaping devices are overly complex in structure and use many drive components such as cylinders, which not only makes them expensive but also requires frequent maintenance and repair after long-term use, severely reducing the reliability of the bushing shaping equipment in the later stages. Based on this, a composite bushing machining shaping device is proposed to solve the above problems. Utility Model Content

[0003] To address the technical problems in the maintenance of bushing forming equipment, this utility model provides a forming device for composite bushing processing.

[0004] This utility model is achieved using the following technical solution: a shaping device for processing composite bushings, comprising a processing table, two limiting platforms fixedly connected to the upper side of the processing table, each of the two limiting platforms having a slot, and a locking block slidably connected to the inner side of each slot, two slots respectively opened on the lower side of the processing table, the two slots being located directly below the limiting platforms, each slot communicating with the slot, each of the two locking blocks having an oblique sliding groove, each of the oblique sliding grooves having a push rod slidably connected to the inner side of each oblique sliding groove, the upper ends of the two push rods being fixedly connected to a push platform, a bushing positioning mechanism for positioning the bushing being provided on one side of each of the two limiting platforms, a push platform driving mechanism being provided above the push platform, and a shaping component fixedly connected to the lower side of the push platform.

[0005] As a further improvement to the above solution, the bushing positioning mechanism includes multiple slide rods that are slidably connected to both of the two locking blocks. One end of each of the multiple slide rods on each side is fixedly connected to a mounting block. A clamping plate is inserted into one side of each of the two mounting blocks. An elastic buffer mechanism is provided at the end of each slide rod away from the clamping plate.

[0006] As a further improvement to the above solution, positioning bolts are provided on the upper side of both mounting blocks.

[0007] As a further improvement to the above solution, the elastic buffer mechanism includes a threaded stop block that is threadedly connected to the end of each slide rod away from the clamping plate, and a spring is provided between each threaded stop block and the locking block, the spring being sleeved on the outside of the slide rod.

[0008] As a further improvement to the above solution, the push table driving mechanism includes a frame fixedly connected to the upper side of the processing table, a fixing plate fixedly connected to the upper side of the frame, a hydraulic cylinder fixedly connected to the upper side of the fixing plate, and the output end of the hydraulic cylinder extending downward and fixedly connected to the upper side of the push table.

[0009] As a further improvement to the above solution, a placement slot is installed on the processing table, and the placement slot is configured to cooperate with the shaping component.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model uses a hydraulic cylinder to drive the clamps on both sides to position and fix the bushing. After the bushing is positioned and fixed, the hydraulic cylinder continues to descend, pushing the shaping component below to shape the bushing. Compared with the method of positioning the bushing using cylinders on both sides, it achieves the effects of simple structure, high efficiency, robustness and durability, and high reliability.

[0012] 2. This utility model uses an installation block inserted between the clamping plates and positioning bolts to quickly replace clamping plates of different sizes and curvatures to adapt to bushings of different radii, making it highly practical. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] Example:

[0021] Please combine Figures 1-4 This embodiment of a shaping device for processing composite bushings includes a processing table 1. Two limiting platforms 8 are fixedly connected to the upper side of the processing table 1. Each limiting platform 8 has a slot 16. A locking block 2 is slidably connected to the inner side of each slot 16. Locking plates are provided on both sides of the locking block 2. Two slots 12 are respectively opened on the lower side of the processing table 1. The slots 12 are reserved spaces for push rods 7 to pass through. The two slots 12 are located directly below the limiting platforms 8. Each slot 12 is connected to the slot 16. An inclined sliding groove 15 is respectively opened on the two locking blocks 2. A push rod 7 is slidably connected to the inner side of each inclined sliding groove 15. A push table 6 is fixedly connected to the upper end of the two push rods 7. A bushing positioning mechanism for positioning the bushing is provided on one side of each of the two limiting platforms 8. A push table driving mechanism is provided above the push table 6. A shaping component 11 is fixedly connected to the lower side of the push table 6.

[0022] Please combine Figure 4 As shown, the bushing positioning mechanism includes two slide rods 13 that are slidably connected to the two locking blocks 2. One end of each of the two slide rods 13 is fixedly connected to a mounting block 18. A prismatic groove is provided on one side of the mounting block 18. A clamping plate 9 is inserted into one side of each of the two mounting blocks 18. A prismatic rod is installed on the back side of the clamping plate 9, which can be directly inserted into the prismatic groove. An elastic buffer mechanism is provided at the end of each slide rod 13 away from the clamping plate 9.

[0023] Please combine Figure 4 As shown, both mounting blocks 18 are provided with positioning bolts 17 on their upper sides. The clamping plates 9 can be quickly replaced through the positioning bolts 17 to adapt to bushings of different radii.

[0024] Please combine Figure 4 As shown, the elastic buffer mechanism includes a threaded stop 19 that is threadedly connected to the end of each slide rod 13 away from the clamping plate 9. A spring 14 is provided between each threaded stop 19 and the locking block 2. The spring 14 is sleeved on the outside of the slide rod 13. One end of the spring 14 is fixedly connected to the threaded stop 19, and the other end is fixedly connected to one side of the locking block 2.

[0025] With the above technical solution, when the clamping plate 9 has not reached the outside of the bushing, the spring 14 is in a natural state. When the clamping plate 9 achieves abutment and positioning fixation on the outside of the bushing, the spring 14 gradually stretches. In addition, when the shaping component 11 completes the maximum pressing height required for shaping, the spring 14 also reaches the maximum stretch length, that is, the slide rod 13 and the locking block 2 reach the maximum relative displacement.

[0026] Please combine Figure 1 The push table drive mechanism includes a frame 3 fixedly connected to the upper side of the processing table 1, a fixed plate 4 fixedly connected to the upper side of the frame 3, a hydraulic cylinder 5 fixedly connected to the upper side of the fixed plate 4, and the output end of the hydraulic cylinder 5 extending downward and fixedly connected to the upper side of the push table 6.

[0027] Please combine Figure 1 As shown, a placement groove 10 is installed on the processing table 1. The placement groove 10 is configured to cooperate with the shaping component 11. The center of the placement groove 10 is hollowed out so that scrap iron filings generated during the shaping process can be discharged from below.

[0028] The implementation principle of the shaping device for composite bushing processing in this application embodiment is as follows: The bushing to be shaped is placed in the placement groove 10, the hydraulic cylinder 5 is activated, and the push table 6 is pushed downward, which drives the push rods 7 on both sides to move downward at the same time. The push rods 7 slide inside the inclined slide groove 15, and the push rods 7 on both sides pass through the slot 12 downward along the inclined slide groove 15. Under the pushing action of the push rods 7, the two clamping blocks 2 move towards the bushing along the clamping groove 16 at the same time, which drives the clamping plate 9 to approach the outside of the bushing until the bushing is clamped and positioned from both sides. At this time, the spring 14 has not yet deformed, and the shaping component 11 below the push table 6 is still above the bushing. Then, the hydraulic cylinder 5 continues to push the push table 6 downward. At this time, due to the obstruction of the bushing, the clamping block 2 moves relative to the slide rod 13, and the elastic deformation stretches. The shaping component 11 smoothly enters the bushing to achieve the shaping effect.

[0029] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
