Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a sawing system. Background Art

[0002] Sawing refers to the process of processing workpieces using tools such as serrated tools (such as saw blades, circular saw blades, saw belts) or thin grinding wheels. Sawing specifically includes operations such as splitting, cutting, and sawing grooves on the workpiece. It is widely used in equipment manufacturing, automotive industry, and construction industry.

[0003] There are two sawing methods in the prior art: method 1, manual sawing, for example, a worker holds a serrated tool by hand to saw the workpiece; method 2, automatic sawing using a sawing machine. At present, the structure of the sawing machine usually uses a driving member to drive the sawing tool to rotate, thereby realizing automatic sawing. The structure of the sawing machine can refer to a profile sawing mechanism disclosed in the Chinese utility model patent with patent number ZL202222359245.6 (authorization announcement number CN219358121U), and another example is a plastic mold sawing mechanism disclosed in the Chinese utility model patent with patent number ZL202221446872.7 (authorization announcement number CN217372528U).

[0004] The manual sawing method of the prior art is time-consuming and labor-intensive, inefficient, and the sawtooth cutter is sharp, so the sawing process is extremely dangerous; although the automatic sawing method using a sawing machine can solve the time-consuming and labor-intensive and inefficient problems of the manual sawing method, the automatic sawing method still has the following limitations: First, the sawing cutter of the sawing mechanism shown in the above two patents rotates quickly under the drive of the driving member. Since the above sawing cutters are all exposed to the outside without a protective structure, workers are very likely to accidentally touch the high-speed running sawing cutter and cause a safety accident; second, since the sawing cutter will generate a large amount of waste residue during the sawing process, if it is not cleaned in time, it will affect the sawing process, and the exposed sawing cutter will drive debris to fly around during the high-speed operation, so it is difficult to clean. For this reason, further improvements to the prior art are needed. Utility Model Content

[0005] The first technical problem to be solved by the utility model is to provide a sawing system which can ensure the personal safety of workers in view of the above-mentioned prior art.

[0006] The second technical problem to be solved by the utility model is to provide a sawing system which can clean the waste residue without affecting the sawing in view of the above-mentioned prior art.

[0007] The technical solution adopted by the utility model to solve the above-mentioned first technical problem is: the sawing system comprises:

[0008] A sawing station, comprising a sawing mechanism and a bracket for mounting the sawing mechanism, wherein the sawing mechanism comprises a driving member mounted on the bracket and a sawing tool drivingly connected to a power output shaft of the driving member;

[0009] The invention is characterized in that:

[0010] A clamping mechanism is mounted on the bracket and arranged on the periphery of the sawing tool, the clamping mechanism includes at least one set of clamping components, and a receiving space for placing the workpiece to be sawed is formed between each set of clamping components, and the sawing part of the sawing tool partially extends into the receiving space, so that the sawing tool rotates under the drive of the driving member to saw the workpiece to be sawed in the receiving space;

[0011] The protection mechanism is installed on the bracket and arranged on the outer periphery of the sawing tool, and together with the clamping mechanism, constitutes a protection component for surrounding the sawing part of the sawing tool.

[0012] There are many structures of the above-mentioned protection mechanism, the simplest of which is: the protection mechanism includes a protection cover installed on a bracket and open toward the sawing tool, and the sawing part of the sawing tool extends into the protection cover and can rotate relative to the protection cover.

[0013] In order to solve the second technical problem mentioned above, the bracket is also connected with a collection box for collecting waste residues generated by sawing. The collection box is located below the sawing tool and has an open upper end.

[0014] In order to enable the above-mentioned collection box to not only collect waste slag but also play a protective role, and to achieve a dual purpose, preferably, the sawing tool is a circular saw disk arranged vertically, and the circular saw disk is suspended on a bracket. The circular saw disk can rotate around its center under the drive of a driving member, and the circular saw disk at least partially extends into the collection box. The protective cover is arranged above the collection box, and the protective cover and the collection box together constitute the above-mentioned protective mechanism.

[0015] Preferably, the clamping components are in two groups, and the two groups of clamping components are respectively arranged on the left and right sides of the circular saw disk and are enclosed together with the protective cover and the collection box to form the above-mentioned protective component.

[0016] There are many kinds of structures of the clamping assembly. In order to make the structure simpler, each group of clamping assemblies includes an upper clamping plate and a lower clamping plate arranged at a relative interval from top to bottom. The upper clamping plate and the lower clamping plate are provided with a notch arranged toward the sawing part of the sawing tool on one side close to the sawing tool. The sawing part of the sawing tool can rotate in the notch. The above-mentioned accommodation space is formed between the upper clamping plate and the lower clamping plate. The upper clamping plate and the lower clamping plate are fixedly mounted on the bracket, or at least one of the upper clamping plate and the lower clamping plate is constrained on the bracket in an adjustable position. In addition to forming an accommodation cavity for placing the workpiece to be sawed, the upper clamping plate and the lower clamping plate can hide the sawing part of the sawing tool in the accommodation cavity to improve the user's operating safety, and can also play the role of clamping the workpiece.

[0017] In order to facilitate the cleaning of waste residue, the collection box has a collection section that gradually shrinks from top to bottom, and a discharge port for waste residue discharge is opened at the bottom of the collection section. In this way, the waste residue entering the collection box will automatically slide to the discharge port on the inner wall surface of the collection section, greatly improving the cleaning efficiency.

[0018] In order to clean up the large waste particles and avoid the large waste particles from clogging the discharge port, a filter screen is provided in the collection box, the outer periphery of the filter screen is connected to the inner wall of the collection box, and a handle is provided on the filter screen for easy picking.

Replacing manual grasping of the workpiece to be sawed by the robot can further improve the safety of the workers. In addition, the working efficiency of the robot is much higher than that of manual labor, so the sawing efficiency is greatly improved.

[0020] In order to realize full automation of the sawing process, the sawing system further comprises:

[0021] A loading station is provided with a loading mechanism for loading the workpiece to be sawed, so that the workpiece to be sawed is loaded to the sawing station;

[0022] The unloading station is provided with an unloading mechanism for unloading the workpiece after sawing, so that the workpiece after sawing is unloaded from the sawing station;

[0023] The above-mentioned robot constitutes a transfer component for transporting workpieces between the loading station to the sawing station and between the sawing station and the unloading station;

[0024] The second controller is electrically connected to the first controller and the driving member, and the second controller is configured to coordinate the loading, sawing and unloading work of each robot.

[0025] Compared with the prior art, the advantage of the utility model lies in that a clamping mechanism is arranged on the periphery of the sawing tool, the clamping mechanism forms a receiving space for placing the workpiece to be sawed and the sawing part of the sawing tool partially extends into the receiving space. Therefore, the clamping mechanism can play a role in clamping the workpiece on the one hand, and on the other hand, the clamping mechanism and the protective mechanism together constitute a protective component surrounding the sawing part of the sawing tool, thereby protecting the workers, preventing the workers from accidental contact, and improving production safety.

[0032] The sawing station includes a sawing mechanism 1 and a bracket 10 for mounting the sawing mechanism 1. The sawing mechanism 1 includes a driving member 11 mounted on the bracket 10 and a sawing tool 12 connected to a power output shaft of the driving member 11. Figure 1 As shown, the bracket 10 is a vertically arranged square tube; in this embodiment, the driving member 11 is a driving motor arranged along the front-to-back direction, and the circular saw disk 12 for sawing the workpiece is arranged vertically. The circular saw disk is suspended at the top of the bracket 10, and the circular saw disk can rotate around its center under the drive of the driving member 11.

[0033] The clamping mechanism is installed on the bracket 10 and is arranged on the periphery of the sawing tool 12. The clamping mechanism includes at least one group of clamping components 21. An accommodating space 22 for placing the workpiece to be sawed is formed between each group of clamping components 21. The sawing part of the sawing tool 12 partially extends into the accommodating space 22, so that the sawing tool 12 rotates under the drive of the driving member 11 and saws the workpiece to be sawed in the accommodating space 22; the protective mechanism 3 is installed on the bracket 10 and is arranged on the periphery of the sawing tool 12, and together with the clamping mechanism, it constitutes a protective component for surrounding the sawing part of the sawing tool 12.

[0034] like Figure 2 and Figure 3 As shown, the protection mechanism 3 in this embodiment includes a protection cover 31 mounted on the bracket 10 and open toward the sawing tool 12.

In addition, in order to facilitate the cleaning and collection of waste residues, a plugging member 42 for inserting into the discharge port to block the discharge port is also provided in the collection box. When collecting waste residues, the plugging member 42 blocks the discharge port, so that the waste residues will be collected in the collection box. When cleaning the waste residues in the collection box, it is only necessary to take the plugging member 42 out of the discharge port, and the waste residues will automatically be discharged from the discharge port. In this embodiment, the circular saw disc at least partially extends into the collection box 4, and the protective cover 31 is arranged above the collection box 4. The protective cover 31 and the collection box 4 together constitute the above-mentioned protective mechanism 3.
