Description

Technical Field

[0001] This invention relates to the technical field of testing systems for motorcycle crankshaft assembly production, specifically a testing system for motorcycle crankshaft assembly production. Background Technology

[0002] The testing system for motorcycle crankshaft assembly production is a device that tests the power output of the gears at one end of a fixed motorcycle crankshaft.

[0003] Existing testing systems for motorcycle crankshaft assemblies use a single, fixed crankshaft assembly. This results in time-consuming disassembly and reassembly, leading to discontinuous testing and reduced efficiency. Furthermore, the crankshaft assembly is not fixed after rotation, causing instability and affecting testing accuracy. Additionally, these systems only test power output; alignment checks are required after disassembly, limiting functionality. Moreover, the need for multiple fixation points for external support increases the risk of misalignment at connection points, hindering proper installation. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of reduced working efficiency of the testing system for motorcycle crankshaft assembly production, affected testing effect of the testing system for motorcycle crankshaft assembly production, poor functionality of the testing system for motorcycle crankshaft assembly production, and affected normal installation of the testing system for motorcycle crankshaft assembly production, and to propose a testing system for motorcycle crankshaft assembly production.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] Design a testing system for motorcycle crankshaft assembly production, including a top frame and support legs. A control structure is connected to the front of the top frame, and positioning structures are connected to the left and right sides of the front of the outer wall of the control structure.

A base plate is fixed to the bottom of the support legs. Mounting structures are connected to the front and rear ends of the top of the base plate. Second connecting plates are fixed to the left and right sides of the base plate.

[0007] Preferably, the control structure includes a straight cylinder, a straight rod, a round opening, a first screw, a handle, a concave plate, a second screw, a convex plate, and a first clamping plate;

[0008] The front of the outer wall of the straight cylinder is rotatably connected to the front of the top frame. The inner wall of the straight cylinder is slidably engaged with the outer wall of the straight rod. The top of the straight rod is machined with multiple round openings. The top of the straight cylinder is threadedly connected to the outer wall of the first screw. The bottom of the outer wall of the first screw is inserted into the inner wall of the round openings. The top of the first screw is fixedly connected to the bottom of the handle. The rear end face of the straight rod is fixedly connected to the front of the concave plate. The upper and lower sides of the concave plate are respectively threadedly connected to the outer wall of the second screw. The inner side of the outer wall of the second screw is rotatably connected to the outer wall of the convex plate. The inner side of the convex plate is fixedly connected to the outer side of the first clamping plate. One end of the first clamping plate is in contact with the inner wall of the concave plate.

[0009] Preferably, a second clamping plate is fixedly connected to the upper and lower sides of the inner wall of the concave plate, and a rotating rod is fixedly connected to the outer side of the two second screws.

[0010] Preferably, the positioning structure includes a curved plate, a round rod, a round plate, and a spring;

[0011] The inner side of the curved plate is fixedly connected to the front end of the outer wall of the straight cylinder. The inner wall of the curved plate is slidably engaged with the outer wall of the round rod. The front side of the round rod is fixedly connected to the rear end face of the round plate. The outer wall of the round rod is sleeved with the inner wall of the spring. The two ends of the spring are fixedly connected to the front side of the curved plate and the rear end face of the round plate, respectively.

[0012] Preferably, the rear of the outer wall of the round rod is inserted into the front round opening of the top frame.

[0013] Preferably, the measuring structure includes a square plate, a horizontal plate, a scale, and a vertical plate;

[0014] The bottom of the square plate is fixedly connected to the top of the top frame, the inner wall of the square plate is slidably engaged with the outer wall of the horizontal plate, the front of the horizontal plate is machined with scales, and the inner side of the horizontal plate is fixedly connected to the outer side of the straight plate.

[0015] Preferably, a vertical plate is fixedly connected to the rear top of the top frame, and a straight cylinder is rotatably connected to the inner wall of the vertical plate.

[0016] Preferably, the top of the straight cylinder is threaded with a bolt, and the rear end face of the straight cylinder is fixed with a handle.

[0017] Preferably, the mounting structure includes a support plate, a sliding groove, a bent rod, and a first connecting plate;

[0018] The bottom of the support plate is fixedly connected to the top of the base plate. A groove is machined on the outer side of the support plate. The inner wall of the groove is slidably engaged with the inner side of the outer wall of the bent rod. The bottom of the bent rod is fixedly connected to the inner side of the top of the first connecting plate.

[0019] The present invention proposes a testing system for motorcycle crankshaft assembly production, which has the following advantages: by controlling the downward rotation of the upper second screw in the control structure, the first clamping plate is moved downward in conjunction with the convex plate, so that the first clamping plate and the second clamping plate fix the motorcycle crankshaft assembly. During the conversion, the straight cylinder and the straight rod drive the concave plate to rotate 180 degrees, so that the lower first clamping plate and the second clamping plate rotate to the upper position, and then the new motorcycle crankshaft assembly is fixed. At this time, the motorcycle crankshaft assembly that has rotated to the lower position can also be disassembled, thereby improving the working efficiency of the testing system for motorcycle crankshaft assembly production.

[0020] By pulling the circular plate forward in the positioning structure, the circular rod is moved forward, causing the circular rod to detach from the front of the top frame. Then, the straight cylinder rotates on the front of the top frame. Subsequently, the circular plate is released, and the spring provides a rebound force, causing the circular plate to move the circular rod backward. The rear of the outer wall of the circular rod is inserted into the circular opening on the front of the top frame, thus fixing the position of the straight cylinder and preventing wobbling. This ensures the testing effect of the testing system used in the production of motorcycle crankshaft assemblies.

[0021] By measuring the horizontal plate in the structure being pushed inwards on the inner wall of the square plate, the inner side of the straight plate is in contact with the outer wall of the fixed motorcycle crankshaft assembly. The scale position on the front of the horizontal plates on both sides is checked. If the scale is consistent, it means that the motorcycle crankshaft assembly is on the same axis, which increases the functionality of the testing system for motorcycle crankshaft assembly production.

[0022] The position of the first connecting plate is adjusted by sliding the bent rod in the inner wall of the slide groove. Then, the external bolts pass through the first connecting plate and are threaded to the connecting surface to complete the fixing of the detection system, avoid connection conflicts, and ensure the normal installation of the detection system for motorcycle crankshaft assembly production.

[0030] The present invention will be further described below with reference to the accompanying drawings:

[0031] Please see Figure 1-6 In this embodiment, a testing system for motorcycle crankshaft assembly production includes a top frame 1 and a support leg 8. A control structure 2 is connected to the front of the top frame 1. Positioning structures 3 are connected to the left and right sides of the front of the outer wall of the control structure 2. The four bottom corners of the top frame 1 are fixedly connected to the top of the support leg 8. Measuring structures 4 are connected to the left and right sides of the top of the top of the top frame 1. A base plate 9 is fixedly connected to the bottom of the support leg 8. Mounting structures 5 are connected to the front and rear ends of the top of the base plate 9. Second connecting plates 10 are fixedly connected to the left and right sides of the base plate 9.

[0032] Control structure 2 includes a straight cylinder 201, a straight rod 202, round openings 203, a first screw 204, a handle 205, a concave plate 206, a second screw 207, a convex plate 208, and a first clamping plate 209. The front of the outer wall of the straight cylinder 201 is rotatably connected to the front of the top frame 1. The straight cylinder 201 rotates through the bearing on the front of the top frame 1 under force. The inner wall of the straight cylinder 201 is slidably engaged with the outer wall of the straight rod 202. The straight rod 202 can adjust the position of the concave plate 206 by sliding back and forth through the inner wall of the straight cylinder 201 under force. The top of the straight rod 202 is machined with multiple round openings 203. The top of the straight cylinder 201 is threadedly connected to the outer wall of the first screw 204. The bottom of the outer wall of the first screw 204 is inserted into the inner wall of the round openings 203. After the first screw 204 is inserted into the round openings 203, it fixes the straight rod 202. The first screw 204 is fixedly connected to the top of the handle 205, which facilitates the rotation of the first screw 204 up and down. The rear end face of the straight rod 202 is fixedly connected to the front face of the concave plate 206. The upper and lower sides of the concave plate 206 are threadedly connected to the outer wall of the second screw 207. The inner side of the outer wall of the second screw 207 is rotatably connected to the outer wall of the convex plate 208. The inner side of the outer wall of the second screw 207 rotates with the outer wall of the convex plate 208. The inner side of the convex plate 208 is fixedly connected to the outer side of the first clamping plate 209. One end of the first clamping plate 209 is in contact with the inner wall of the concave plate 206. The upper and lower sides of the inner wall of the concave plate 206 are fixedly connected to the second clamping plates 7. The outer sides of the two second screws 207 are fixedly connected to the rotating rods 6, which facilitate the rotation of the second screws 207.

[0033] By controlling the downward rotation of the upper second screw 207 in the control structure 2, the first clamping plate 209 is moved downward in conjunction with the convex plate 208, so that the first clamping plate 209 and the second clamping plate 7 fix the motorcycle crankshaft assembly. During the conversion, the straight cylinder 201 and the straight rod 202 drive the concave plate 206 to rotate 180 degrees, so that the lower first clamping plate 209 and the second clamping plate 7 rotate to the upper position, and then fix the new motorcycle crankshaft assembly. At this time, the motorcycle crankshaft assembly that has rotated to the lower position can also be disassembled, which improves the working efficiency of the testing system for motorcycle crankshaft assembly production.

[0034] The positioning structure 3 includes a curved plate 301, a round rod 302, a round plate 303, and a spring 304. The inner side of the curved plate 301 is fixedly connected to the front end of the outer wall of the straight cylinder 201. The inner wall of the curved plate 301 is slidably engaged with the outer wall of the round rod 302. The round rod 302 slides back and forth through the inner wall of the curved plate 301 under force. The front side of the round rod 302 is fixedly connected to the rear end face of the round plate 303. The outer wall of the round rod 302 is sleeved with the inner wall of the spring 304. The two ends of the spring 304 are fixedly connected to the front side of the curved plate 301 and the rear end face of the round plate 303, respectively. After the round plate 303 moves forward under force, it rebounds due to the elastic force of the spring 304. The rear of the outer wall of the round rod 302 is inserted into the front round opening of the top frame 1.

[0035] By pulling the circular plate 303 forward in the positioning structure 3, the circular rod 302 is moved forward, causing the circular rod 302 to detach from the front of the top frame 1. Then, the straight cylinder 201 rotates on the front of the top frame 1. Subsequently, the circular plate 303 is released, and the spring 304 provides a rebound force, causing the circular plate 303 to move the circular rod 302 backward. The rear of the outer wall of the circular rod 302 is inserted into the circular opening on the front of the top frame 1, thus fixing the position of the straight cylinder 201 and preventing shaking, thereby ensuring the testing effect of the testing system used for motorcycle crankshaft assembly production.

[0036] The measuring structure 4 includes a square plate 401, a horizontal plate 402, a scale 403, and a straight plate 404. The bottom of the square plate 401 is fixedly connected to the top of the top frame 1. The inner wall of the square plate 401 is slidably engaged with the outer wall of the horizontal plate 402. The horizontal plate 402 slides left and right through the inner wall of the square plate 401 under force. The horizontal plate 402 has a scale 403 machined on its front side. The inner side of the horizontal plate 402 is fixedly connected to the outer side of the straight plate 404.

[0037] By measuring the movement of the horizontal plate 402 in structure 4 inward against the inner wall of the square plate 401, the inner side of the straight plate 404 is in contact with the outer wall of the fixed motorcycle crankshaft assembly. The position of the scale 403 on the front of the horizontal plates 402 on both sides is checked. If the scale 403 is consistent, it means that the motorcycle crankshaft assembly is on the same axis, which increases the functionality of the testing system for motorcycle crankshaft assembly production.

[0038] A vertical plate 11 is fixedly connected to the rear top of the top frame 1. A straight cylinder 12 is rotatably connected to the inner wall of the vertical plate 11. A bolt 13 is threadedly connected to the top of the straight cylinder 12. A handle 14 is fixedly connected to the rear end face of the straight cylinder 12. The installation structure 5 includes a support plate 501, a sliding groove 502, a bent rod 503 and a first connecting plate 504. The bottom of the support plate 501 is fixedly connected to the top of the bottom plate 9. A sliding groove 502 is machined on the outer side of the support plate 501. The inner wall of the sliding groove 502 is slidably engaged with the inner side of the outer wall of the bent rod 503. The bent rod 503 slides left and right through the inner wall of the sliding groove 502 under force. The bottom of the bent rod 503 is fixedly connected to the inner side of the top of the first connecting plate 504.

[0039] The position of the first connecting plate 504 is adjusted by sliding the bent rod 503 in the mounting structure 5 left and right on the inner wall of the slide groove 502. Then, the external bolt passes through the first connecting plate 504 and is threaded to the connecting surface to complete the fixing of the detection system, avoid connection conflicts, and ensure the normal installation of the detection system for motorcycle crankshaft assembly production.

[0040] Working principle:

[0041] When using this device, first, the bottom of the base plate 9 is aligned with the connecting surface. Then, external bolts pass through the second connecting plate 10 and are fixed to the connecting surface. Next, the bent rod 503 slides left and right on the inner wall of the slide groove 502 to adjust the position of the first connecting plate 504. Then, external bolts pass through the first connecting plate 504 and are threadedly connected to the connecting surface to complete the fixing of the detection system. Then, one end of the motorcycle crankshaft assembly is inserted into the inner wall of the straight cylinder 12. Then, the bolt 13 rotates downward to press the motorcycle crankshaft assembly against it. At this time, the rear of the motorcycle crankshaft assembly is located in the upper second clamping plate 7. Then, the upper rotating rod 6 drives the upper second screw 207 to rotate downward, which in turn cooperates with the convex plate 208 to drive the first clamping plate 209 to move downward, so that the first clamping plate 209 cooperates with the second clamping plate 7 to fix the motorcycle crankshaft assembly. During the conversion, the straight cylinder 201 cooperates with the straight rod 202 to drive the concave plate 206 to rotate 180 degrees, so that the lower first clamping plate 209 and the second clamping plate 7 rotate to the upper position. The new motorcycle crankshaft assembly is fixed. At this time, the motorcycle crankshaft assembly that has rotated to the bottom can also be disassembled. After the motorcycle crankshaft assembly is fixed, the horizontal plate 402 is pushed inward on the inner wall of the square plate 401. At this time, the inner side of the straight plate 404 is in contact with the outer wall of the fixed motorcycle crankshaft assembly. Check the position of the scale 403 on the front of the two horizontal plates 402. If the scale 403 is consistent, it means that the motorcycle crankshaft assembly is on the same axis. With the help of the handle 14, the straight cylinder 12 is rotated, which can rotate the fixed motorcycle crankshaft assembly to realize power detection. Pull the round plate 303 forward, which will drive the round rod 302 forward, so that the round rod 302 is separated from the front of the top frame 1. Then the straight cylinder 201 rotates on the front of the top frame 1. Then release the round plate 303. The spring 304 provides the rebound force, which makes the round plate 303 drive the round rod 302 to move backward. The rear of the outer wall of the round rod 302 is inserted into the round opening on the front of the top frame 1, thus completing the position fixation of the straight cylinder 201.
