Description

Technical Field

[0001] This application relates to the field of chainsaw performance testing technology, specifically to a chainsaw oil consumption testing mechanism. Background Technology

[0002] As a key power tool in forestry, landscaping and other fields, the fuel economy of chainsaws is a core indicator for evaluating product performance and competitiveness.

[0003] Currently, the industry-standard method for testing fuel consumption is to conduct the test on a controlled test bench. The chainsaw's fuel tank is filled to its rated capacity; then, the chainsaw is removed from the test bench, and its total mass is weighed using a precision balance and recorded; next, the chainsaw is started and run for a preset time or completes a specific work cycle, then stopped again, disassembled, and weighed. The difference in mass between the two weighings yields the fuel consumption for that time period.

[0004] However, this traditional disassembly and weighing method requires a cycle of "stopping, disassembling, weighing, reassembling, and restarting" for each measurement. Frequent disassembly and reassembly is not only time-consuming and labor-intensive, but also severely restricts testing efficiency, making it difficult to conduct long-term, multi-condition continuous fuel consumption tests.

[0005] Therefore, there is an urgent need to design a testing mechanism that can measure the oil consumption of chainsaws without disassembling and reassembling them. Utility Model Content

[0006] The purpose of this application is to propose a chainsaw oil consumption testing mechanism to solve the problem in the prior art that the existing chainsaw oil consumption testing requires frequent disassembly and assembly, which seriously affects the testing efficiency.

[0007] To achieve the above objectives, this application proposes a chainsaw oil consumption testing mechanism, including a base plate, a movable plate movably mounted on the base plate for chainsaw installation, and a weighing component mounted on the movable plate and the base plate. The movable plate can move up and down, and there is an origin and a sawing start point in the trajectory of the movable plate's up and down movement. When the movable plate is at the origin, the weighing component weighs the chainsaw. After the weighing component finishes weighing the movable plate at the origin, the movable plate begins to move to the sawing start point. Subsequently, the movable plate returns to the origin and performs sawing on the chainsaw. After the movable plate returns to the origin, the weighing component weighs the chainsaw again, thereby obtaining the oil consumption of the chainsaw cutting process.

[0008] Optionally, the weighing assembly includes a linkage rod mounted on a movable plate, a linkage plate mounted on the linkage rod, an abutment structure and a sensor respectively mounted on the linkage plate and the base plate.

[0009] Optionally, the distance between the moving plate and the ground is less than the distance between the moving plate and the bottom surface when the moving plate is located at the sawing start point.

[0010] Alternatively, when the abutment structure is mounted on the linkage plate, the sensor is mounted on the base plate.

[0011] Optionally, a mounting post is mounted on the substrate, and a first pressure plate is movably mounted on the mounting post, the bottom surface of the first pressure plate being in contact with the sensor.

[0012] Optionally, a limit plate is installed at the top of the mounting column; when the movable plate moves to the origin, the abutment structure abuts against the first bearing plate.

[0013] Optionally, when the abutment structure is mounted on the substrate, the sensor is mounted on the linkage plate; a connecting post is mounted on the linkage plate, and a second pressure plate is movably mounted on the connecting post, the second pressure plate being in contact with the sensor.

[0014] Optionally, a stop block is installed on the connecting column to contact the top surface of the linkage plate, and a limiting member is installed on the connecting column to contact the second bearing plate; when the moving plate moves to the origin, the abutment structure abuts against the second bearing plate.

[0015] Optionally, the abutment structure includes an abutment post and an abutment block mounted on the abutment post, wherein the abutment block and the abutment post are provided with a connecting structure.

[0016] Optionally, the connection structure includes mounting holes on the abutment block corresponding to the abutment post.

[0017] Optionally, the connection structure also includes an internal thread disposed in the mounting hole and an external thread disposed on the abutment post that engages with the internal thread.

[0018] Optionally, the connecting structure also includes a threaded hole on the abutment block that communicates with the mounting hole, and a locking screw installed in the threaded hole.

[0019] Optionally, the opening direction of the threaded hole is perpendicular to the opening direction of the mounting hole.

[0020] Optionally, the linkage plate and / or the movable plate are provided with connection holes corresponding to the abutment post, and an adjusting element is installed on the abutment post.

[0021] Optionally, the connecting hole is a through hole; the adjusting element is located at the opening of the connecting hole.

Then the moving plate moves to obtain the sawing start point, then the moving plate returns to its original position to saw the lumber. The sawing is completed after the moving plate moves back to the origin, and the weight of the chainsaw is weighed after the moving plate moves back to the origin. The chainsaw oil consumption is obtained based on the difference obtained from the weighing. Attached Figure Description

Detailed Implementation

[0045] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, illustrates this application. Numerous specific details are set forth in the description below to provide a thorough understanding of the invention. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0046] The chainsaw oil consumption test mechanism of this application can be used for testing the oil consumption of chainsaws, and of course it can also be used in other similar application scenarios. The chainsaw oil consumption test mechanism is described in detail below.

[0047] Example 1 See appendix Figure 1 — Figure 9As shown, the feed force adjustment mechanism of the chainsaw inspection equipment of this application includes a base plate 100, a movable plate 200 movably mounted on the base plate 100 for chainsaw mounting, a weighing component 300 mounted on the movable plate 200 and the base plate 100, and a lifting power source 140 mounted on the base plate 100 and connected to the movable plate 200. The movable plate 200 can move vertically and vertically, and its trajectory includes an origin and a sawing starting point.

[0048] This application provides installation conditions for the lifting power source 140 through the setting of the base plate 100; provides installation conditions for the chainsaw through the setting of the moving plate 200; and measures the weight of the chainsaw through the setting of the weighing component 300. When the moving plate 200 is at the origin, the weighing component 300 weighs the chainsaw. After the weighing component 300 finishes weighing the chainsaw at the origin, the moving plate 200 starts to move to the sawing starting point. Then, the chainsaw performs sawing during the process of the moving plate 200 returning to the origin. After the moving plate 200 returns to the origin, the weighing component 300 weighs the chainsaw again, thereby obtaining the oil consumption of the chainsaw cutting process. The sawn material is standard sawn material, and the sawing area is known. The oil consumption is obtained by dividing the oil consumption by the sawing area.

[0049] See appendix Figure 1 — Figure 6 As shown in this application, the weighing assembly 300 includes a linkage rod 310 mounted on a movable plate 200, a linkage plate 320 mounted on the linkage rod 310, an abutment structure 330 and a sensor 340 respectively mounted on the linkage plate 320 and the base plate 100. It should be noted that the sensor 340 is a pressure sensor, and this sensor 340 is electrically connected to an external PLC controller.

[0050] This application uses the linkage 310 to transmit the movement of the moving plate 200, enabling the linkage plate 320 to move with the moving plate 200 and guiding the lifting and lowering movement of the moving plate 200. The linkage plate 320 also provides installation and adjustment for the abutment structure 330 or the sensor 340, so that when the moving plate 200 is at its origin, the abutment structure 330 can abut against the sensor 340, allowing the sensor 340 to weigh the chainsaw. It should be noted that when the abutment structure 330 abuts against the sensor 340, the weight of the moving plate 200, the chainsaw, the linkage 310, and the linkage plate 320 is all pressed against the sensor 340 through the abutment structure 330.

[0051] See appendix Figure 3 — Figure 6As shown in this application, when the abutment structure 330 is installed on the linkage plate 320, the sensor 340 is installed on the base plate 100; a mounting post 110 is installed on the base plate 100, and a first pressure plate 120 is movably installed on the mounting post 110, the bottom surface of the first pressure plate 120 is in contact with the sensor 340; wherein, a limit plate 130 is installed on the top of the mounting post 110 by means of threaded connection or bolt.

[0052] This application uses the mounting post 110 to guide the movement of the first pressure plate 120, ensuring that the first pressure plate 120 can apply pressure to the sensor 340 during movement. The first pressure plate 120 increases the contact area of ​​the abutment structure 330, ensuring that the abutment structure 330 can press against the first pressure plate 120, concentrating the pressure received. The rigidity of the first pressure plate 120 distributes the pressure into a uniform force, which is then transmitted to the sensing diaphragm of the sensor 340, ensuring that the diaphragm deforms under its designed operating mode to obtain accurate readings. The limiting plate 130 effectively prevents the first pressure plate 120 from separating from the mounting post 110, ensuring that the first pressure plate 120 can contact the abutment structure 330 and transmit pressure to the sensor 340.

[0053] See appendix Figure 3 — Figure 6 As shown in this application, the abutment structure 330 includes an abutment post 331 and an abutment block 332 mounted on the abutment post 331. The abutment block 332 and the abutment post 331 are provided with a connecting structure 333. The connecting structure 333 includes a mounting hole 3331 on the abutment block 332 corresponding to the abutment post 331, an internal thread in the mounting hole 3331, and an external thread on the abutment post 331 that meshes with the internal thread.

[0054] This application adjusts the installation height of the abutment block 332 by setting the abutment post 331, ensuring that the abutment block 332 can contact the first pressure plate 120; the abutment block 332 allows for adjustment of the contact position, ensuring that when the abutment block 332 contacts the first pressure plate 120, the moving plate 200 is suspended and does not contact the lifting block 150; the mounting hole 3331 provides conditions for the connection of the abutment post 331; the internal and external threads allow the abutment block 332 to move up and down along the abutment post 331, and the abutment block 332 can stop at any position.

[0055] See appendix Figure 1 and Figure 2As shown in this application, a lifting power source 140 connected to a movable plate 200 is mounted on the substrate 100, and a lifting block 150 is mounted on the lifting power source 140 to drive the substrate 100 to rise. It should be noted that the lifting power source 140 is a telescopic cylinder or a telescopic electric cylinder.

[0056] This application, through the setting of the lifting power source 140, can drive the moving plate 200 to move upward, ensuring that the moving plate 200 can drive the chainsaw to move, so that the moving plate 200 can drive the chainsaw to reset, and the chainsaw can cut the lumber; through the setting of the lifting block 150, the lifting power source 140 can drive the moving plate 200 to move unidirectionally, and with the cooperation of the proximity switch or photoelectric sensor in the prior art, the moving plate 200 can rise to a designated position and stop, and then the lifting power source 140 resets, and the moving plate 200 performs free fall reset movement.

[0057] See appendix Figure 1 , Figure 2 and Figure 7 As shown in this application, a vertical plate 210 is mounted on the movable plate 200, a rotary power source 220 is mounted on the vertical plate 210, and a throttle control block 230 is mounted on the rotary power source 220. It should be noted that the rotary power source 220 is a stepper motor or a servo motor.

[0058] This application provides an installation position for the rotary power source 220 by setting the upright plate 210; the rotary power source 220 is used to drive the throttle control block 230 to rotate, so that the throttle control block 230 can control the throttle of the chainsaw.

[0059] See appendix Figure 1 — Figure 9 As shown, the working principle of the fuel consumption testing mechanism in this application is as follows: The first step is to add fuel to the chainsaw, then fix the chainsaw to the moving plate 200 with bolts, and the operator starts the machine. In the second step, since the moving plate 200 is at the origin position, the gravity of the moving plate 200, the connecting rod 310, the chainsaw and the linkage plate 320 presses on the sensor 340 through the abutment structure 330. At this time, the sensor 340 sends the sensed gravity to the PLC controller. Third, the PLC controller controls the lifting power source 140 to drive the moving plate 200 to move upward. When the moving plate 200 moves to the sawing starting point, the PLC controller receives the corresponding photoelectric switch and proximity switch signals and stops the lifting power source 140. Fourth, the PLC controller controls the rotary power source 220 to start, which drives the throttle control block 230 to rotate, thus starting the throttle of the chainsaw; at the same time, the operator uses existing technology (e.g., conveyor roller conveying equipment) to transport the sawn timber to the bottom of the existing chainsaw. Fifth step, the PLC controller controls the lifting power source 140 to reset. The reset speed is greater than the speed of the chainsaw falling freely. During the reset process, the chainsaw cuts the lumber. In the sixth step, when the moving plate 200 resets to its original position, the sensor 340 sends the sensed gravity to the PLC controller. The PLC controller obtains the difference between the two gravity values ​​to get the chainsaw's oil consumption, and then calculates the chainsaw's oil consumption based on the area of ​​the sawn timber.

[0060] Example 2 See appendix Figure 10 — Figure 13 As shown, the difference between this embodiment and the above embodiment is that, in this embodiment, when the abutment structure 330 is installed on the base plate 100, the sensor 340 is installed on the linkage plate 320; a connecting post 350 is installed on the linkage plate 320, and a second pressure plate 360 ​​is movably installed on the connecting post 350, which is in contact with the sensor 340; wherein, a stop block 351 is installed on the connecting post 350 that contacts the top surface of the linkage plate 320, and a limiting member 370 for contacting the second pressure plate 360 ​​is installed on the connecting post 350.

[0061] In this embodiment, the sensor 340 is mounted on the linkage plate 320. At this time, the second pressure plate 360 ​​also needs to be mounted on the linkage plate 320. In this case, the weight of the second pressure plate 360 ​​will not be applied to the sensor 340, reducing the use of the sensor 340 and thus protecting the sensor 340.

[0062] Example 3 See appendix Figure 1 and Figure 15 As shown, the difference between this embodiment and the above embodiment is that, in this embodiment, the connecting structure 333 includes a mounting hole 3331 on the abutment block 332 corresponding to the abutment post 331, a threaded hole 3332 on the abutment block 332 communicating with the mounting hole 3331, and a locking screw 3333 installed in the threaded hole 3332; the opening direction of the threaded hole 3332 is perpendicular to the opening direction of the mounting hole 3331. It should be noted that the inner wall of the mounting hole 3331 is smooth.

[0063] In this embodiment, the threaded hole 3332 is provided to provide an installation position for the locking screw 3333; the locking screw 3333 is provided to fix the abutment block 332, so that the abutment block 332 can be fixedly installed at any position.

[0064] Example 4 See appendix Figure 16 — Figure 19 As shown, the difference between this embodiment and the above embodiment is that, in this embodiment, the linkage plate 320 and / or the movable plate 200 are provided with connecting holes 321 corresponding to the abutment post 331, and an adjusting member 322 is installed on the abutment post 331; the connecting hole 321 is a through hole; the adjusting member 322 is located at the opening of the connecting hole 321. It should be noted that the adjusting member 322 is a nut.

[0065] In this embodiment, the connection hole 321 is provided for the installation and adjustment of the abutment post 331. The connection hole 321 is set as a through hole, and with the setting of the adjustment component 322, it is ensured that the abutment post 331 can be movably installed on the moving plate 200 or the linkage plate 320. The position of the abutment post 331 can be adjusted, thereby increasing the position adjustment range of the abutment block 332.

[0066] The above embodiments are illustrative of this application and are not intended to limit this application. Any simple modifications to this application are within the protection scope of this application.
