Description

Technical Field

[0001] This utility model relates to the field of testing tooling technology, and in particular to a speed testing tooling for engine production. Background Technology

[0002] An engine speed testing fixture is a device used to test and measure engine speed. Its main function is to check whether the engine can operate normally within a specified speed range during engine production, assembly, or maintenance. This fixture is typically connected to the engine's control system to monitor engine speed in real time and provide accurate data via instruments or displays.

[0003] However, when using this speed testing fixture for engine production, sometimes the device cannot be adjusted according to the size of its shaft because the engine model to be tested is different, which affects the subsequent testing structure and reduces the practicality of the device. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a speed testing fixture for engine production.

[0005] This utility model is achieved by the following technical solution: a speed testing fixture for engine production, including a support plate, a mounting frame fixedly connected to the upper end of the support plate, a fixing frame fixedly connected to the upper end of the support plate, a speed sensor fixedly connected to the inner wall of the fixing frame, and a connecting component provided inside the mounting frame;

[0006] The connecting assembly includes a connecting sleeve, a sliding ring slidably connected to the surface of the connecting sleeve, an inclined block fixedly connected inside the sliding ring, a rotating sleeve rotatably connected to the surface of the sliding ring, a sliding plate slidably connected to the inner wall of the connecting sleeve, a pressure frame fixedly connected to the surface of the sliding plate, connecting frames fixedly connected to both sides of the sliding plate, a spring fixedly connected to one end of the connecting frame near the center of the connecting sleeve, an anti-slip pad fixedly connected to one end of the sliding plate near the center of the connecting sleeve, a rotating shaft fixedly connected to the left end of the connecting sleeve, a bearing provided on the surface of the rotating shaft, a rotating disk fixedly connected to the left end of the rotating shaft, and a detection groove opened on the left end of the rotating disk.

[0007] The above technical solution uses a rotating sleeve to drive the sliding plates at both ends to press the anti-slip pads against the output end of the middle engine, which achieves the purpose of conveniently connecting different models of engines to the device, making the subsequent use of the device more convenient and improving the practicality of the device.

[0008] As a further improvement to the above scheme, the number of sliding plates is two, and the two sliding plates are symmetrically distributed around the center of the connecting sleeve.

[0009] As a further improvement to the above solution, the surface of the pressure frame is slidably connected to the surface of the inclined block, and the two sides of the inclined block are slidably connected to the inner wall of the connecting sleeve.

[0010] The above technical solution provides a connection and limit for the subsequent movement of the pressure frame and sliding plate by the inclined block during sliding, making the device more convenient to use.

[0011] As a further improvement to the above solution, the surface of the connecting frame is slidably connected to the inner wall of the connecting sleeve, and the end of the spring contacts the inner wall of the connecting sleeve.

[0012] The above technical solution enables the sliding plate and pressure frame to automatically reset when the rotating sleeve is rotated back, so that the device can continue to be used.

[0013] As a further improvement to the above solution, the inner wall of the rotating sleeve and the surface of the connecting sleeve are both provided with trapezoidal threads, and the inner wall of the rotating sleeve and the surface of the connecting sleeve are threadedly connected.

[0014] The above technical solution, which uses a trapezoidal thread to connect the connecting sleeve and the rotating sleeve, achieves the goal of conveniently driving the sliding plate for clamping while also enabling the rotating sleeve to have a certain self-locking capability after adjustment, making the device more convenient and quick to use.

[0015] As a further improvement to the above scheme, the speed sensor is located at the left end of the rotating disk.

[0016] As a further improvement to the above solution, the surface of the bearing is fixedly connected to the inner wall of the mounting bracket.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention involves inserting the output end of the engine to be tested into the hole at the right end of the connecting sleeve and fixing its position. Then, the rotating sleeve is rotated to make it rotate on the surface of the connecting sleeve. At this time, due to the thread between the connecting sleeve and the rotating sleeve, the rotating sleeve is driven to move to the left, and at the same time, the sliding ring on the inner wall of the rotating sleeve is displaced. While the sliding ring is displaced, the inclined block on its inner wall applies pressure to the inclined surface of the pressure frame, thereby squeezing the pressure frame towards the center of the connecting sleeve. This causes the sliding plate and anti-slip pad to move closer to the center of the engine output end and squeeze it, thus fixing the engine output end to facilitate subsequent measurement of the engine speed.

[0019] This invention operates by starting the engine, which causes the output end to drive the connecting sleeve to rotate. At the same time, the connecting sleeve and other parts such as the rotating disk rotate. As the rotating disk rotates, the detection groove on its surface moves in a circular motion. Meanwhile, the speed sensor on the left end detects the position of the detection groove, thereby conveniently measuring the engine speed and transmitting the data to an external display for recording the engine speed.

[0028] Example 1

[0029] Please combine Figure 1-5 This embodiment of a speed testing fixture for engine production includes a support plate 1, a mounting bracket 2 fixedly connected to the upper end of the support plate 1, a fixing bracket 3 fixedly connected to the upper end of the support plate 1, a speed sensor 4 fixedly connected to the inner wall of the fixing bracket 3, and a connecting component 5 provided inside the mounting bracket 2.

[0030] The connecting assembly 5 includes a connecting sleeve 501, a sliding ring 502 slidably connected to the surface of the connecting sleeve 501, a wedge block 503 fixedly connected inside the sliding ring 502, a rotating sleeve 504 rotatably connected to the surface of the sliding ring 502, a sliding plate 505 slidably connected to the inner wall of the connecting sleeve 501, a pressure frame 506 fixedly connected to the surface of the sliding plate 505, connecting frames 507 fixedly connected to both sides of the sliding plate 505, a spring 508 fixedly connected to one end of the connecting frame 507 near the center of the connecting sleeve 501, and a spring 508 fixedly connected to one end of the sliding plate 505 near the center of the connecting sleeve 501. The device is fixedly connected with an anti-slip pad 509. A rotating shaft 510 is fixedly connected to the left end of the connecting sleeve 501. A bearing 511 is provided on the surface of the rotating shaft 510. A rotating disk 512 is fixedly connected to the left end of the rotating shaft 510. A detection groove 513 is opened at the left end of the rotating disk 512. The design of using the rotating sleeve 504 to drive the sliding plates 505 at both ends to drive the anti-slip pad 509 to squeeze the middle engine output end achieves the purpose of conveniently connecting different models of engines to the device, making the subsequent use of the device more convenient and improving the practicality of the device.

[0031] There are two sliding plates 505, which are symmetrically distributed around the center of the connecting sleeve 501.

[0032] The surface of the pressure frame 506 is slidably connected to the surface of the inclined block 503, and the two sides of the inclined block 503 are slidably connected to the inner wall of the connecting sleeve 501.

[0033] The surface of the connecting bracket 507 is slidably connected to the inner wall of the connecting sleeve 501, and the end of the spring 508 is in contact with the inner wall of the connecting sleeve 501.

[0034] The inner wall of the rotating sleeve 504 and the surface of the connecting sleeve 501 are both provided with trapezoidal threads. The inner wall of the rotating sleeve 504 and the surface of the connecting sleeve 501 are threaded together. The design of using trapezoidal threads to connect the connecting sleeve 501 and the rotating sleeve 504 achieves the purpose of conveniently driving the sliding plate 505 for clamping while also enabling the rotating sleeve 504 to have a certain self-locking ability after adjustment, making the use of the device more convenient and quick.

[0035] The speed sensor 4 is located at the left end of the rotating disk 512.

[0036] The surface of bearing 511 is fixedly connected to the inner wall of mounting bracket 2.

[0037] The implementation principle of a speed testing fixture for engine production in this embodiment is as follows: When using this fixture, the output end of the engine to be tested is first inserted into the hole at the right end of the connecting sleeve 501 and its position is fixed. Then, the rotating sleeve 504 is rotated to make it rotate on the surface of the connecting sleeve 501. At this time, due to the thread between the connecting sleeve 501 and the rotating sleeve 504, the rotating sleeve 504 is driven to move to the left, and at the same time, the sliding ring 502 on the inner wall of the rotating sleeve 504 is displaced. While the sliding ring 502 is displaced, the inclined block 503 on its inner wall applies pressure to the inclined surface of the pressure frame 506, thereby squeezing the pressure frame 506 towards the center of the connecting sleeve 501, thereby driving the sliding plate 505 and the anti-slip pad 509 to move towards the center of the engine output end and squeeze it, thereby completing the fixation of the engine output end. After connection 501 is completed, the engine is started to operate, causing its output end to drive the connecting sleeve 501 to rotate. At the same time, the connecting sleeve 501 and the rotating disk 512 and other parts rotate. While the rotating disk 512 rotates, the detection groove 513 on its surface moves in a circular motion. Simultaneously, the left-end speed sensor 4 detects the position of the detection groove 513, thereby conveniently measuring the engine speed and transmitting the data to an external display for recording. This device uses the rotating sleeve 504 to drive the upper and lower sliding plates 505 to squeeze the engine output end, and the engine drives the rotating disk 512 to rotate in conjunction with the left-end speed sensor 4 for recording. This design achieves the purpose of conveniently fixing the output end of different models of engines and measuring their speed, improving the overall practicality of the device.

[0038] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
