Abstract
Description
Technical Field
[0001] This utility model relates to the field of leaf spring processing technology, and in particular to an automatic deburring device for leaf springs. Background Technology
[0002] Modern automobile manufacturing technology is becoming increasingly sophisticated. Leaf springs are a core component in automobile manufacturing, and therefore, the precision required for leaf spring production is relatively high. During the manufacturing process, the two ends of the leaf spring need to be deburred and ground.
[0003] Currently, most existing edge grinding equipment uses a handheld grinding machine to grind the edges of the leaf spring. However, because the leaf spring is curved, uneven grinding at the edges is easy to occur during grinding. Utility Model Content
[0004] To address the problems in existing technologies, this utility model provides an automatic deburring device for leaf springs. The basic concept of the technical solution adopted by this utility model to solve the aforementioned technical problems is as follows:
[0005] An automatic deburring device for leaf springs includes an arc-shaped frame with a handle fixed to the top. Adjustment grooves are provided on both sides of the arc-shaped frame near the bottom edge. Push blocks are slidably arranged inside the two adjustment grooves. A grinding component is provided on one side of each of the two push blocks. Adjustment bolts are provided on both sides of the arc-shaped frame. One end of each of the two adjustment bolts is threaded through the interior of the adjustment groove and rotatably connected to one side of the push block.
[0006] Optionally, guide openings are provided on both sides of the inner walls of the two adjustment slots, and guide blocks that slide and engage inside the guide openings are fixed on the outer surfaces of the two push blocks.
[0007] Optionally, the polishing assembly includes an arc-shaped block, one side of which is fixed to the outer surface of the push block, and the other side of which is arc-shaped.
[0008] Optionally, the arc surface of the arc block faces the inner side of the arc frame and is in contact with the inner arc surface of the arc frame.
[0009] Optionally, a grinding disc is provided on the outer side of the arc surface of the arc block, an annular groove is formed on the arc surface of the arc block, and an annular ring is fixed at the bottom of the grinding disc.
[0010] Optionally, the annular ring is slidably engaged inside the annular groove, and a motor is installed inside the arc-shaped block, with the output end of the motor fixed to the bottom of the grinding disc.
[0011] Optionally, the arc-shaped block has an annular cavity inside, a flexible tube is fixed to the top of the arc-shaped block, the flexible tube is connected to the inside of the annular cavity, and a plurality of diversion holes penetrating to the outer arc surface are equidistantly formed on the outer surface of the annular cavity along the circumferential direction.
[0012] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:
[0013] 1. In this utility model, adjustment grooves are provided on both sides of the bottom of the arc frame, so that the grinding component can be adjusted to grind leaf springs of different curvatures. In actual use, the arc frame needs to be locked on the outside of the leaf spring to be ground, so that the inner arc surface of the arc frame is adapted to the curvature of the leaf spring to be ground. Then, by rotating the adjustment bolt, the grinding component is driven to move to both sides of the leaf spring, so that the two sides of the leaf spring can be ground when the arc frame slides along the leaf spring.
[0014] 2. In this utility model, when the grinding component is working, lubricating oil is injected into the interior of the annular cavity through a hose, and then flows to the bottom of the grinding disc through the diversion hole on the annular cavity. The grinding disc is driven by the start motor to grind the outer surface of the leaf spring. During the rotation of the grinding disc, the mutual engagement of the annular ring and the annular groove makes its rotation more stable. When the push block is driven to slide by the adjusting bolt, the mutual engagement of the guide port and the guide block can prevent it from shaking. At the same time, it can counteract the longitudinal force generated on the push block during grinding and avoid damage to the threaded connection of the adjusting bolt. Attached Figure Description

Detailed Implementation
[0023] The present invention will now be described in further detail with reference to the accompanying drawings.
[0024] Example 1, as Figure 1-4 As shown, this utility model provides a technical solution for an automatic deburring device for leaf springs: it includes an arc-shaped frame 1, a handle 2 fixed to the top of the arc-shaped frame 1, adjustment grooves 4 are provided on both sides of the arc-shaped frame 1 near the bottom edge, push blocks 5 are slidably arranged inside the two adjustment grooves 4, a grinding component is provided on one side of the two push blocks 5, and adjustment bolts 3 are provided on both sides of the arc-shaped frame 1. One end of the two adjustment bolts 3 is threaded through into the interior of the adjustment groove 4 and rotatably connected to one side of the push block 5.
[0025] The effect achieved by the entire embodiment 1 is that adjustment grooves 4 are opened on both sides of the bottom of the arc frame 1, so that the grinding component can be adjusted to grind leaf springs with different curvatures. In actual use, the arc frame 1 needs to be locked on the outside of the leaf spring to be ground, so that the inner arc surface of the arc frame 1 is adapted to the curvature of the leaf spring to be ground. Then, by rotating the adjustment bolt 3, the grinding component is driven to move to both sides of the leaf spring, so that the two sides of the leaf spring can be ground when the arc frame 1 slides along the leaf spring.
[0026] Example 2, as Figure 1-4As shown, guide openings 8 are provided on the inner walls of both sides of the two adjusting grooves 4. Guide blocks 9 are fixed on the outer surfaces of the two push blocks 5 and are slidably engaged inside the guide openings 8. The grinding assembly includes an arc-shaped block 6. One side of the arc-shaped block 6 is fixed on the outer surface of the push block 5, and the other side of the arc-shaped block 6 is arc-shaped. The arc surface of the arc-shaped block 6 faces the inner side of the arc frame 1 and is in contact with the inner arc surface of the arc frame 1. A grinding disc 7 is provided on the outer side of the arc surface of the arc-shaped block 6. An annular groove 14 is provided on the arc surface of the arc-shaped block 6. An annular ring 13 is fixed at the bottom of the grinding disc 7 and is slidably engaged inside the annular groove 14. A motor 10 is provided inside the arc-shaped block 6. The output end of the motor 10 is fixed at the bottom of the grinding disc 7. An annular cavity 11 is provided inside the arc-shaped block 6. A flexible hose 15 is fixed at the top of the arc-shaped block 6 and is connected to the interior of the annular cavity 11. Multiple diversion holes 12 that penetrate to the outer arc surface are provided at equal intervals along the circumferential direction on the outer surface of the annular cavity 11.
[0027] The effect achieved by the entire embodiment 2 is that when the grinding assembly is working, the lubricating oil is injected into the interior of the annular cavity 11 through the hose 15, and then flows to the bottom of the grinding disc 7 through the diversion hole 12 on the annular cavity 11. The grinding disc 7 is driven by the starting motor 10 to grind the outer surface of the leaf spring. During the rotation of the grinding disc 7, the mutual engagement of the annular ring 13 and the annular groove 14 makes its rotation more stable. When the push block 5 is driven to slide by the adjusting bolt 3, the mutual engagement of the guide port 8 and the guide block 9 can prevent it from shaking. At the same time, it can counteract the longitudinal force generated on the push block 5 during grinding and avoid damage to the threaded connection of the adjusting bolt 3.
[0028] Working principle: Adjustment grooves 4 are provided on both sides of the bottom of the arc-shaped frame 1, which facilitates the adjustment of the grinding component to grind leaf springs with different curvatures. In actual use, the arc-shaped frame 1 needs to be engaged on the outside of the leaf spring to be ground, so that the inner arc surface of the arc-shaped frame 1 is adapted to the curvature of the leaf spring to be ground. Then, by rotating the adjusting bolt 3, the grinding component is driven to move to both sides of the leaf spring, so that the two sides of the leaf spring can be ground when the arc-shaped frame 1 slides along the leaf spring. When the grinding component is working, lubricating oil is injected into the annular cavity 11 through the hose 15. Inside the annular cavity 11, the water flows to the bottom of the grinding disc 7 through the diversion hole 12. The grinding disc 7 is driven by the starting motor 10 to grind the outer surface of the leaf spring. During the rotation of the grinding disc 7, the interlocking of the annular ring 13 and the annular groove 14 makes its rotation more stable. When the push block 5 is driven to slide by the adjusting bolt 3, the interlocking of the guide port 8 and the guide block 9 can prevent it from shaking. At the same time, it can counteract the longitudinal force generated on the push block 5 during grinding and avoid damage to the threaded connection of the adjusting bolt 3.
