Description

Technical Field

[0001] The utility model is applicable to the field of kerbstone production equipment and provides a self-adaptive kerbstone cutting angle fine grinding machine. Background Art

[0002] Curbstones are stones used for paving urban roads. They are often used to separate and decorate different roads. For safety reasons, the sharp edges of curbstones generally need to be chamfered to prevent safety hazards caused by sharp edges. In conventional curbstone production, the miter saw blade is usually fixed obliquely at a specified height, and then the edge of the curbstone is controlled to move through the miter saw blade. During this process, the miter saw blade cuts the edge of the curbstone into the required chamfered shape. However, in this structure, the height of the miter saw blade is fixed. When the thickness of the curbstone substrate produces a reasonable error that meets the standard due to production reasons, this small thickness deviation will not affect the use of the curbstone. However, when chamfering, the change in thickness of the curbstone base will cause a change in the distance between it and the chamfering saw blade. Since the chamfer size is small, this distance change will be reflected in the change in the size of the chamfer. For example, the thickness of the curbstone is reduced by 2mm, which is not a big change compared to the overall thickness of the curbstone of more than 100mm. However, the thickness of the curbstone is reduced by 2mm, which means that the distance between the curbstone base and the chamfering saw blade increases by 2mm. At this time, when the cutter is chamfering at the same height, the original 4mm chamfer will become a 2mm chamfer, and the size change is very large, which cannot meet the design requirements.

The specific sliding connection mechanism is: the support frame 21 is fixedly provided with two limit guide rods 28, and the lifting seat 22 is fixedly provided with two groups of linear bearings 29, each group of linear bearings 29 includes two linear bearings 29, and the linear bearings 29 groups are slidably adapted to the limit guide rods 28 in a one-to-one correspondence. This structure has good stability and can ensure the precise positioning of the lifting seat 22 when it moves up and down continuously. The support frame 21 is fixedly provided with a lifting drive device 23, and the lifting drive device 23 is drivingly connected to the lifting seat 22 for driving the lifting seat 22 to move up and down. In this embodiment, the lifting drive device 23 adopts a linear cylinder, and the lifting seat 22 is fixedly provided with a saw blade drive device 24. The device 24 is driven and connected with a miter saw blade 25. In this embodiment, the saw blade driving device 24 adopts a motor. The miter saw blade 25 is more chamfered and requires to be inclined compared to the horizontal plane. The saw blade driving device 24 is fixedly connected to a limiting wheel fixing seat 26. The limiting wheel fixing seat 26 is rotatably provided with two curbstone end surface limiting wheels 27. The two curbstone end surface limiting wheels 27 are respectively arranged on the left and right sides of the miter saw blade 25. When the curbstone base body 5 is chamfered, the curbstone end surface limiting wheels 27 always abut against the upper end surface of the curbstone base body 5. In this way, it can be ensured that the relative position between the upper end surface of the curbstone base body 5 and the miter saw blade 25 is always consistent and will not be affected by the slight thickness change of the curbstone; the curbstone limiting and deviation correction module includes fixed limiting plates 3 and a deviation correction unit 4 respectively arranged on both sides of the circulating conveyor belt 1, as shown in the attached figure. Figure 4 As shown, the deflection correction unit 4 includes a deflection correction push plate 44 and a deflection correction drive device, the deflection correction drive device includes a deflection correction drive motor 43 and at least two screw linear drivers 41, two adjacent screw linear drivers 41 are directly driven and connected through a synchronous coupling 42, the synchronous coupling 42 can ensure the synchronous drive of multiple screw linear drivers 41, the deflection correction drive motor 43 is driven and connected with any one of the screw linear drivers 41, the moving ends of the screw linear drivers 41 are fixedly connected with the deflection correction push plate 44, the deflection correction push plate 44 is arranged opposite to the fixed limit plate 3, and as shown in the attached Figure 2 As shown, a plurality of fixed side limiting wheels 31 are arranged on the side of the fixed limiting plate 3 facing the correcting push plate 44 and rotating along the running direction of the circulating conveyor belt 1, and a plurality of correcting side limiting wheels 45 are arranged on the side of the correcting push plate 44 facing the fixed limiting plate 3 and rotating along the running direction of the circulating conveyor belt 1.

[0022] The working principle of this embodiment is as follows:

[0023] The curbstone base 5 is placed on the circulating conveyor belt 1 and begins to be transported. It stops when it is transported to the adaptive corner cutting module 2. The correcting push plate 44 is controlled to move toward the fixed limit plate 3, and finally the curbstone base 5 is clamped between the correcting push plate 44 and the fixed limit plate 3. At this time, the lifting drive device 23 controls the lifting seat 22 to descend until the first curbstone end face limit wheel 27 abuts against the upper end face of the curbstone base 5. The preparation work for chamfering is completed. Then the saw blade drive device 24 is started, and the circulating conveyor belt 1 starts to run again. The curbstone base 5 starts to move toward the corner cutting saw blade 25. Finally, the curbstone base 5 moves past the corner cutting saw blade 25 driven by the circulating conveyor belt 1. During this period, the curbstone base 5 completes the edge chamfering processing under the cutting of the corner cutting saw blade 25, and is finally taken away by the circulating conveyor belt 1 for the next operation.
