Description

Technical Field

[0001] This utility model belongs to the technical field of spring motor testing devices, and in particular relates to a spring motor output torque testing bench. Background Technology

[0002] A spring starter motor is a device that uses the energy stored in a spring to drive the start of equipment. A spring motor mainly consists of five parts: a housing, a spring energy storage device, a release mechanism, a transmission mechanism, and a reset mechanism. It stores energy by compressing or stretching the spring, controls the timing and manner of releasing the spring energy, and then transmits the released energy to the driven component (such as the flywheel of an engine) to perform its function.

[0003] Spring motor assemblies require break-in before leaving the factory, and their output torque also needs to be tested. Currently, different equipment is needed for both break-in and output torque testing of spring motors. This not only increases the need for multiple devices and investment costs, but also makes the operation cumbersome, requiring the spring motors to be moved back and forth, increasing manual labor intensity. Therefore, we propose a spring motor output torque test bench to solve the above-mentioned problems. Utility Model Content

[0004] In view of this, in order to solve the problems of traditional equipment having relatively simple functions, requiring different equipment for the break-in of spring motors and the detection of output torque, resulting in high equipment investment costs, cumbersome operation, and high labor intensity, this utility model provides a spring motor output torque test bench.

[0029] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this utility model. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] Example 1: Please refer to Figure 1 , Figure 2 As shown, this embodiment provides a spring motor output torque test bench, including a mounting base 1, a mounting seat 2, a lever scale 3, a geared motor 4, a flange support 5, a fixed seat 7, a connecting seat 8, and a flywheel 9. The geared motor 4 is fixedly mounted on one side of the top of the mounting base 1 via the mounting seat 2. The lever scale 3 is fixedly connected to the other side of the top of the mounting base 1. The flange support 5 is fixedly connected to the top of the mounting base 1 and located between the mounting seat 2 and the lever scale 3. The spring motor body 6 is flanged and connected to one side of the flange support 5. The output shaft of the geared motor 4 and the input shaft of the spring motor body 6 are connected via a rotating arm. The fixed seat 7 is fixedly connected to the top of the mounting base 1 and located between the flange support 5 and the lever scale 3. The connecting seat 8 is fixedly connected to the top of the fixed seat 7. The flywheel 9 is rotatably connected to one side of the connecting seat 8. An external gear ring 11 that meshes with the internal gear of the spring motor body 6 is fixedly sleeved on the outer wall of the flywheel 9. First, the spring motor body 6 is mounted on the flange support 5 via a flange. One end of the spring motor body 6 passes through one side of the flange support 5, and its gear meshes with the external gear ring 11. The input hexagonal shaft of the spring motor body 6 is connected to the output shaft of the geared motor 4 via a rotating arm. Next, the geared motor 4 is started, driving the input hexagonal shaft of the spring motor body 6 to rotate, simultaneously storing energy in the compressed disc spring. After the input hexagonal shaft has rotated to the specified number of revolutions, the geared motor 4 stops rotating. The release shaft of the spring motor body 6 is manually pushed, at which point the flywheel 9 with a brake wheel is driven to rotate through gear meshing, thus completing the break-in operation of the product. Repeating this process achieves the required number of break-in cycles for the product.

[0031] In one aspect of this embodiment, a counter 10 electrically connected to the geared motor 4 is mounted on the top of the mounting base 2 via a bracket. By installing the counter 10, the number of rotations of the output shaft of the geared motor 4 can be counted, thereby determining the number of rotations of the input hexagonal shaft of the spring motor body 6. When the input hexagonal shaft rotates to the specified number of rotations, the geared motor 4 can be controlled to automatically stop working, and then the spring motor body 6 is released to drive the flywheel 9 to rotate, completing one break-in cycle.

[0032] This invention can be used in the field of spring motor output torque test benches, and can also be applied to other fields.

[0033] Example 2: This example is a further improvement on the previous example: as follows Figures 1-5 As shown, the torque transmission assembly includes a fixing member 13. A sleeve 12 is fixedly connected to the side of the flywheel disk 9 away from the connecting seat 8. The fixing member 13 is detachably fixedly connected to the sleeve 12. A straight rod 15 is fixedly connected to the fixing member 13. A pressure block 18 is hinged to the end of the straight rod 15 away from the fixing member 13, and the pressure block 18 is placed flat on the tray of the lever scale 3. The fixing member 13 is fixed to the flywheel disk 9 through the sleeve 12, and then the straight rod 15 is installed so that the straight rod 15 extends horizontally, while the pressure block 18 is placed flat on the tray of the lever scale 3. The pressure of the pressure block 18 on the lever scale 3 is adjusted to its initial value of zero. If adjustment is difficult, the initial pressure value can also be recorded. With this design, the torque that causes the flywheel disk 9 to rotate can be converted into the pressure of the pressure block 18 on the lever scale 3 through the straight rod 15. Then, the spring motor body 6 is installed according to the break-in test method, and its energy is stored by the geared motor 4. The reading on the lever scale 3 is recorded every time the geared motor 4 drives the input hexagonal shaft to rotate one revolution, until the required maximum number of energy storage revolutions is reached. Finally, the output torque is calculated from the reading on the lever scale 3, thus the output torque of the spring motor body 6 can be measured. When the product needs to be broken in again, the fixing part 13 can be removed from the sleeve 12.

[0034] In one aspect of this embodiment, the fastener 13 includes a first semicircular block 131 and a second semicircular block 132. The first semicircular block 131 and the second semicircular block 132 are hinged together by a pin 133 and fastened to the outer wall of the sleeve 12. The side of the first semicircular block 131 away from the pin 133 has an integrally formed first horizontally extending outward support arm 134, and the side of the second semicircular block 132 away from the pin 133 has an integrally formed second horizontally extending outward support arm 135. The first support arm 134 and the second support arm 135 are arranged vertically parallel and connected by bolts. A straight rod 15 is fixedly connected to the second support arm 135. When installing the fastener 13, the first semicircular block 131 and the second semicircular block 132 are first opened to a certain extent, then placed on the sleeve 12, and then closed again so that they are properly fastened to the outer wall of the sleeve 12. At this time, bolts are inserted from the bottom of the first arm 134 upwards through the through holes on the first arm 134 and the second arm 135 to connect them, so that they are tightly fastened to the outer wall of the sleeve 12, thereby completing the fixed installation of the fastener 13. When locking the fastener 13, the level of the straight rod 15 can be adjusted by rotating the entire fastener 13, so that the pressure block 18 can be placed flat on the tray of the lever scale 3. Rubber pads 16 are fixedly provided on the inner walls of the first semicircular block 131 and the second semicircular block 132. Through the contact and compression between the rubber pads 16 and the outer wall of the sleeve 12, the connection of the fastener 13 can be made more stable, thereby ensuring that the flywheel 9 can better transmit torque output when rotating.

[0035] In one aspect of this embodiment, the straight rod 15 has at least two screw holes 151, and the top of the second arm 135 also has at least two threaded holes 1351 that mate with the screw holes 151. The straight rod 15 is fixedly connected to the second arm 135 by screws. The connection of the straight rod 15 to the second arm 135 by screws facilitates the disassembly and installation of the straight rod 15, making it easy to replace and also easy to assemble and use the device.

[0036] In one aspect of this embodiment, a fixing block 14 is fixedly connected to the top side of the fixing base 7. A support block 17 extending outwards is integrally provided on one side of the fixing block 14, and the support block 17 is located directly below the first support arm 134, and is simultaneously fixedly connected to the first support arm 134 and the second support arm 135 by bolts. Fixing the first support arm 134 to the support block 17 simultaneously further improves the stability of the installation of the fixing member 13. It also serves as a rotational limit for the first support arm 134, ensuring the normal transmission of torque.

[0037] However, as is well known to those skilled in the art, the working principles and wiring methods of the geared motor 4 and the counter 10 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
