Description

Technical Field

[0001] This utility model belongs to the field of boring tooling technology, and specifically refers to a boring tooling for a vehicle frame. Background Technology

[0002] Motorcycle frame, such as Figure 1 As shown, the system includes a main body 1, on which a riser 2 is welded. The riser 2 has a through hole 3 inside. Typically, both ends of the through hole 3 need to be bored. Boring increases the diameter of the hole at both ends, improving accuracy and reducing surface roughness. Since the riser 2 is fixed to the main body 1 by welding, it will tilt and deform during the welding process, meaning the two ends of the riser 2 will not be on the same straight line.

[0003] Chinese utility model patent (publication number CN220178244U, application date 2023.07.24, publication date 2023.12.15) discloses a double-head boring machine for motorcycle frame risers, including a machine body, a servo power head, and a waste chip conveyor. An electrical box is fixedly connected to the right end of the machine body. The servo power head is located on one side of the electrical box, and one end of the servo power head is connected to a servo motor via a shaft. The servo power head includes a cutting tool, a tool holder, and bolts. The cutting tool is screwed to the servo power head via the tool holder and bolts. A protective cover is fixedly connected to the back of the machine body, and the waste chip conveyor is fixedly installed at one end of the protective cover. Two sets of servo power heads are provided, with two sets of opposing reference cylinders between them. A clamping mold is provided between the two sets of reference cylinders to facilitate the reference cylinders pushing the end face of the pipe fitting against the positioning reference, allowing the clamping mold to clamp the pipe fitting.

[0004] The shortcomings of the above-mentioned double-head boring machine for motorcycle frame risers are: since the deformation degree and direction of each riser are different, using a fixed tooling for boring will result in uneven wall thickness at the end of the through hole, with thinner sections being weaker and more prone to breakage. Utility Model Content

[0005] The purpose of this utility model is to provide a boring tool for a vehicle frame, wherein the distance between the outer wall of the end of the riser and the axis of the boring tool is equal to the radius of the riser, thereby ensuring that the wall thickness of the through hole of the riser is uniform, the riser is strong, and it is not easily damaged.

[0006] This utility model is implemented as follows: A boring tool for a vehicle frame includes a base plate with two mounting seats spaced back-to-back on the base plate. Two supports are positioned between the two mounting seats. The supports are arranged back-to-back, and each support is screwed with an adjusting screw whose axis is arranged laterally. The rod of the adjusting screw passes through the support and extends out of the right end face of the support. A drive plate is provided on the right side of the support.

[0008] In the above-mentioned boring tool for a vehicle frame, there are two clamping blocks, which are respectively located to the right of the corresponding adjusting screws. The clamping blocks are mounted on the drive plate by connecting screws. The shank of the connecting screw passes through the drive plate and is screwed to the clamping block. There is a certain distance between the drive plate and the clamping block. The clamping block can rotate and move relative to the drive plate.

[0009] In the aforementioned boring fixture for a vehicle frame, the dial indicator includes a body, a sleeve, and a measuring rod. The sleeve is installed in the mounting hole of the mounting base and is tightened and fixed by a set screw.

[0023] The present invention will be further described below with reference to specific embodiments. See also: Figure 1 —5: A boring tool for a vehicle frame includes a base plate 11. Two mounting seats 12 are spaced apart on the base plate 11, and two supports 13 are provided between the two mounting seats 12. The two supports 13 are arranged one after the other, and each support 13 is screwed with an adjusting screw 14 whose axis is arranged laterally. The rod of the adjusting screw 14 passes through the support 13 and extends out of the right end face of the support 13. A drive plate 15 is provided on the right side of the support 13. The drive plate 15 is driven by a power device 16 and slides laterally on the base plate 11. A clamping block 17 for pressing the riser 2 onto the right end of the adjusting screw 14 is installed on the left side of the drive plate 15. Each mounting seat 12 is equipped with a dial indicator 18 for detecting whether the end of the riser 2 is skewed. The measuring rod of the dial indicator 18 is arranged laterally, and the measuring head of the dial indicator 18 extends out of the mounting seat 12 and abuts against the outer wall of the riser 2.

[0024] Before boring, the two dial indicators 18 are zeroed. The specific steps are as follows: Place the unwelded riser 2 (without deformation) on the boring fixture, adjust the two adjusting screws 14 so that the axis of the riser 2 is in the same straight line as the axis of the two boring tools, and then zero the two dial indicators 18. At this time, the distance between the measuring head of the two dial indicators 18 and the axis of the boring tool is equal to the radius of the riser 2.

[0025] The specific clamping process of the frame: such as Figure 1-4 As shown, the upright tube 2 of the frame is placed between the right end of the adjusting screw 14 and the clamping block 17. The power unit 16 drives the drive plate 15 to move to the left, causing the clamping block 17 to press the upright tube 2 onto the right end of the adjusting screw 14. The two adjusting screws 14 are rotated until both dial indicators 18 are zero, so that the distance between the outer wall of the end of the upright tube 2 and the axis of the boring tool is equal to the radius of the upright tube 2, thereby ensuring that the wall thickness of the boring hole is uniform.

[0026] Adjustment process: If dial indicator 18 rotates clockwise, it means that the end of the riser 2 on that side is tilted toward dial indicator 18. In this case, the adjusting screw 14 on the side closer to dial indicator 18 needs to be adjusted to move to the right to push out the end of the riser 2 on that side. If dial indicator 18 rotates counterclockwise, it means that the end of the riser 2 on that side is tilted away from dial indicator 18. In this case, the adjusting screw 14 on the side closer to dial indicator 18 needs to be adjusted to move to the left, so that the end of the riser 2 on that side moves to the left under the push of clamp 17.

[0027] This utility model is provided with two mounting bases 12, and a dial indicator 18 is installed on the mounting base 12 to detect whether the end of the riser 2 is deviated. At the same time, two supports 13 are provided, and an adjusting screw 14 is installed on the support 13. The deviated riser 2 is adjusted by adjusting the adjusting screw 14 so that the distance between the outer wall of the end of the riser 2 and the axis of the boring tool is equal to the radius of the riser 2, thereby ensuring that the wall thickness of the through hole 3 of the riser 2 is uniform, the riser 2 is strong and not easily damaged.

[0028] To facilitate placing the frame on the tooling and clamping, the mounting base 12 has an abutment block 19 on its right side. The abutment block 19 has a left V-shaped opening 20 with its opening facing the right side on its right end. The clamping block 17 has a right V-shaped opening 21 with its opening facing the left side on its left end. During boring, the two ends of the riser 2 are respectively clamped between the corresponding left V-shaped opening 20 and right V-shaped opening 21. The measuring head of the dial indicator 18 extends into the left V-shaped opening 20 and abuts against the outer wall of the riser 2.

[0029] The specific installation structure of clamp 17 is as follows: Figure 3-5 As shown, there are two clamping blocks 17, which are located to the right of the corresponding adjusting screws 14. The clamping blocks 17 are mounted on the drive plate 15 by connecting screws 22. The rod of the connecting screw 22 passes through the drive plate 15 and is screwed to the clamping block 17. There is a certain distance between the drive plate 15 and the clamping blocks 17. The clamping blocks 17 can rotate and move relative to the drive plate 15, so that the positions of the two clamping blocks 17 pressing against the riser 2 are not on the same straight line, thus avoiding the riser 2 being locked and unable to be adjusted by the adjusting screws 14.

[0030] The dial indicator 18 is mounted in the mounting hole of the mounting base 12 and is fixed by a set screw.

[0031] To extend the length of the measuring rod, a probe 23 is connected to the right end of the measuring rod, and the right end of the probe 23 is the measuring head of the dial indicator 18. In this embodiment, the probe 23 is fixedly connected to the measuring rod by welding.

[0032] Furthermore, the right end of probe 23 passes through the abutment block 19 and extends into the left V-shaped opening 20 to abut against the outer wall of riser 2.

[0033] To better support the riser 2, the right end face of the adjusting screw 14 is flat.

[0034] Structure of power unit 16: The power unit 16 is a hydraulic cylinder fixed on the base plate 11, and the piston rod of the hydraulic cylinder is fixedly connected to the drive plate 15.

[0035] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
