[0002] Chainsaws / gasoline-powered chainsaws are widely used in the fields of logging, garden pruning, construction wood processing, and household firewood sawing. The market share is increasing, and manufacturers are emerging in an endless stream, but the quality is also uneven. Before the chainsaw leaves the factory, testing each unit is an important means to ensure its quality, and it is also the last guarantee to prevent the flow of faulty machines to the market. However, in order to save costs, many small companies use random inspections or fewer inspection items during the test inspection, which greatly reduces the effect of the test. The main reason is that the test device cannot serve the production well, making the test cost very high, time-consuming and labor-intensive.

[0003] For example, with the rise of automation, there are automatic testing devices for chainsaws on the market, but they have great limitations. The detailed startup conditions and problems during operation of each chainsaw cannot be well discovered and recorded, and there are fewer inspection items. In addition, the cost is high, so many small manufacturers do not adopt this method. Instead, they test the machine directly on a simple workbench. This will cause problems in safety protection, environmental exhaust emissions, etc. The labor intensity of the test run will also be relatively high, and the test run efficiency will be reduced. In mass production, it is difficult to guarantee the quality of each chainsaw. Summary of the invention

DETAILED DESCRIPTION

[0015] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is clearly and completely described below in conjunction with the accompanying drawings of the present invention. The directional words mentioned in the following embodiments, such as "up", "down", "left" and "right", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional words used are used to illustrate rather than limit the invention.

[0016] like Figure 1-4 As shown, a multifunctional workbench for testing a chainsaw comprises a workbench 1, on which a mounting platform 2 for mounting a chainsaw 3 is mounted, an exhaust gas collecting device 4 is fixedly connected above the workbench 1, and the exhaust gas collecting device 4 comprises a cover shell 41, on which a connecting port 45 for connecting to an external negative pressure system is provided, an air inlet is provided on the lower side of the cover shell 41, a top suction perforated plate 42 is detachably connected to the air inlet, a side suction perforated plate 44 is provided on the lower side of the top suction perforated plate 42, an upper cover plate 43 for covering holes and adjusting suction is provided on the upper side of the top suction perforated plate 42, and the upper cover plate 43 is slidably connected to the cover shell 41; it is not only convenient for the installation and debugging of the chainsaw 3, but also can flexibly adjust the suction area when the chainsaw 3 is working, maximize the exhaust gas collection efficiency, effectively improve the working environment, and reduce environmental pollution. When the chainsaw 3 needs to be installed, the upper cover 43 can be pushed backward to provide a larger operating space; when the chainsaw 3 starts to work, the upper cover 43 can be pulled forward to increase the air intake area and improve the exhaust gas adsorption effect. The structure is simple, the operation is convenient, and the exhaust gas adsorption effect is good.

[0017] Furthermore, the mounting platform 2 includes a rotating base 21 and a mounting plate 24. The rotating base 21 is connected to the workbench 1 by a fastening bolt 22. The mounting plate 24 is rotatably connected to the rotating base 21 by a rotating shaft 23. A quick clamp 5 for fixing the shell 33 of the chain saw 3 is provided on the mounting plate 24. The quick clamp 5 adopts a design of a rotary spring pressure rod. Specifically, it can fix the handle part of the chain saw 3. After the guide plate 31 and the chain 32 are installed and the tension of the chain 32 is adjusted, the machine can be quickly fixed, so that the fixation of the chain saw 3 is more stable and it is convenient to quickly replace the chain saw 3 of different models or different production numbers, thereby improving the flexibility and efficiency of the test run.

[0018] Furthermore, an arc-shaped guide groove is provided on the rotating base 21, and a guide rod 27 is detachably connected to the mounting plate 24, and the guide rod 27 is inserted into the arc-shaped guide groove. Specifically, the guide rod 27 adopts a cylindrical head hexagon socket screw, and the head is just in the arc-shaped guide groove. The mounting plate 24 can rotate freely within the opening angle range of the arc-shaped arc-shaped guide groove, while also ensuring the stability and accuracy of the mounting plate 24 during the rotation process, which is helpful for the testing requirements of the chain saw 3 at different angles.

[0019] The guide plate 31 of the chainsaw 3 is detachably connected with a stud bolt 26, and the middle part of the stud bolt 26 has no thread setting and is used as a rotating shaft. A fixing seat 25 for fixing the stud bolt 26 is provided on the mounting plate 24. A round hole is processed on the guide plate 31 of the chainsaw 3, and a shaft sleeve is embedded in it. After adjusting the height of the guide plate 31 chain 32 according to the chainsaw 3 product to be debugged as needed, it is fixed to the fixing seat 25 by the stud bolt 26; in this way, the guide plate 31 can be slightly rotated up and down with the center of the bolt on the fixing bracket as the axis, which is convenient for installation and improves work efficiency and safety.

[0020] Furthermore, the side suction hole plate 44 is provided with long strip-shaped grid holes 441, which enhances the suction uniformity and coverage of the side suction hole plate 44 and further improves the exhaust gas collection effect.

[0021] Furthermore, the top suction hole plate 42 is provided with two groups of left and right adsorption holes 421, which respectively correspond to the position of the exhaust port of the muffler exhausting to the left front when the chain saw 3 is started, and the position of the exhaust port of the muffler exhausting to the right front when the machine is rotated for debugging during the test run, so that the suction of the negative pressure system is more targeted and the exhaust gas is discharged more quickly. The upper cover plate 43 is provided with grid holes 431, and the vertical projection of the grid holes 431 can be operated to cover the vertical projection of the adsorption holes 421, so that the upper cover plate 43 can flexibly adjust the suction volume during the sliding process, while ensuring the continuity and efficiency of the suction; when the upper cover plate 43 moves forward, the adsorption holes 421 are partially blocked. At this time, due to the reduction of the air intake area, the suction force of the connected negative pressure system becomes larger, and the phenomenon of exhaust gas escaping due to the pushing of the upper cover plate 43 will not occur. When the upper cover plate 43 is fully pulled out, although the air intake area is enlarged compared with the aforementioned operation, resulting in a smaller suction force of the negative pressure system, the exhaust gas protection in the operating space is more stringent at this time, and no exhaust gas will escape.

[0022] Furthermore, a panel 11 is provided on the workbench 1, and an opening is provided on the front side of the panel 11. The upper cover plate 43 is slidably connected to the panel 11 front and rearward. The rear side, left side and right side of the cover shell 41 are sealed and connected to the panel 11, which effectively prevents the leakage of exhaust gas and enhances the sealing and collection efficiency of the entire exhaust gas collection system.

[0023] Furthermore, a roller is hinged on the upper cover plate 43, a slide groove is installed on the enclosure plate 11, the roller is rollingly connected to the slide groove, and the front side of the upper cover plate 43 is tilted downward by 15 degrees. The cooperation between the roller and the slide groove makes the sliding of the upper cover plate 43 smoother, reduces the operating resistance, and makes the upper cover plate 43 automatically slide forward after lightly pushing the upper cover plate 43, which is convenient for operation and can better guide the exhaust gas into the cover shell 41, further improving the efficiency of exhaust gas collection.
