Description

Technical Field

[0001] This invention relates to the field of vibration measurement technology, and in particular to a vibration measurement device for motor equipment. Background Technology

[0002] After the motor equipment is manufactured, it needs to undergo comprehensive testing to ensure its quality. Vibration testing is an effective way to reflect the quality of motor equipment, and vibration measuring devices are required when conducting vibration testing on motor equipment.

[0003] Existing vibration measurement devices for motor equipment typically measure vibration after the motor equipment is mounted on a flat surface. However, since motor equipment is installed in various ways after being put into normal use (e.g., hanging), different installation angles will have a certain impact on the vibration amplitude of the motor equipment. The vibration measurement results obtained by only testing motor equipment mounted on a flat surface are not universal or accurate. Summary of the Invention

[0004] In view of this, the present invention provides a vibration measuring device for motor equipment to solve the problem that the installation methods of motor equipment after normal use are different, and different installation angles will have a certain impact on the vibration amplitude of the motor equipment. The vibration measurement results obtained by only testing the flat installation are not universal and accurate.

[0005] This invention provides a vibration measuring device for motor equipment, specifically comprising: a main support frame, wherein self-locking worm gears A are provided on the top left and right sides of the main support frame; an installation angle adjustment shaft is rotatably mounted on the inner side of the main support frame; the installation angle adjustment shaft has a cylindrical structure; self-locking worm gears A are provided on the left and right sides of the installation angle adjustment shaft; the self-locking worm gears A are connected to the self-locking worm wheels A; guide members are provided on the left and right sides of the main support frame; the guide members have an arc-shaped structure; an installation angle adjustment member is provided at the center of the installation angle adjustment shaft; a test platform is provided at the outer end of the installation angle adjustment member; an installation groove is opened inside the test platform, and a self-locking worm gear B is provided inside the installation groove.

[0006] Furthermore, an output angle horizontal rotating shaft is rotatably mounted at the center of the top of the test platform; the output angle horizontal rotating shaft has a cylindrical structure; a self-locking worm gear B is provided on the output angle horizontal rotating shaft; the self-locking worm gear B is connected to the self-locking worm wheel B; a clamping platform is provided at the top of the output angle horizontal rotating shaft; clamping grooves are arranged in a cross shape on the upper and lower sides of the clamping platform; the clamping grooves have an oval structure; and an operating component is provided at the front end of the clamping platform.

[0007] Furthermore, the operating component has a U-shaped structure; a clamping driven rod is slidably installed inside the clamping groove; the clamping driven rod has a cylindrical structure; a clamping positioning component is provided at the top of the clamping driven rod; the clamping positioning component has a rectangular structure; a trigger mounting shaft is provided at the center of the interior of the clamping platform; the trigger mounting shaft has a cylindrical structure; a trigger tension plate is provided on the trigger mounting shaft; the trigger tension plate is located inside the clamping platform.

[0008] Furthermore, the trigger pull plate has a disc-shaped structure; a trigger pull groove is provided on the top of the trigger pull plate; the trigger pull groove has an arc-shaped structure; the clamping follower rod is also located inside the trigger pull groove; a follower toothed ring is provided on the outer circumference of the trigger pull plate; the follower toothed ring has a circular ring structure; an operating support plate is provided on the top rear side of the clamping platform; a stroke slide groove is provided on the operating support plate; a stroke slide plate is provided inside the stroke slide groove.

[0009] Furthermore, a motor vibration meter is installed at the inner end of the travel slide plate; a control screw is installed on the rear side of the operating support plate; an operating disc is installed at the top of the control screw; the control screw is connected to the travel slide plate through threads; a drive gear is installed on the outer circumference of the control screw; the drive gear meshes with a follower gear ring; guide slides are installed on the left and right sides of the test platform; the guide slides are also slidably installed inside the guide component.

[0010] Furthermore, when the control screw rotates, it will use its threads to drive the travel slide plate and the vibration meter of the motor device to move along the travel slide groove; when the control screw rotates, it will also drive the follower gear ring and the trigger tension plate to rotate under the action of the drive gear; when the trigger tension plate drives the trigger tension groove to rotate, the trigger tension groove will pull the clamping driven rod inward along the clamping slide groove.

[0011] The beneficial effects are as follows: First, the invention includes an adjustment structure. By rotating the installation angle adjustment shaft in the adjustment structure, the installation angle of the test platform, clamping platform, and the motor equipment placed on it can be adjusted, facilitating multi-angle adjustment of the installation angle of the motor equipment. Simultaneously, by rotating the output angle horizontal rotation shaft in the adjustment structure, the output angle of the clamping platform and the motor equipment placed on it can be adjusted, facilitating multi-directional adjustment of the output orientation of the motor equipment itself. This allows the vibration measuring device to measure the vibration of motor equipment at different installation angles and different output angles, improving the universality and accuracy of the vibration measurement results. Furthermore, the adjustment structure in this invention has a self-locking function, achieving angle self-locking after adjusting the installation angle and output angle of the motor equipment, thus improving the flexibility and convenience of the device during use.

[0012] Second, this invention includes a clamping structure. By manually rotating a control screw, the screw moves the travel slide plate and the vibration meter of the motor equipment downwards along the travel groove, facilitating contact between the vibration measuring end of the vibration meter and the motor equipment for vibration measurement. Furthermore, as the control screw rotates, it also drives the follower gear ring, trigger tension plate, and trigger tension groove to rotate under the action of the drive gear. This causes the trigger tension groove to pull the clamping driven rod and clamping positioning component inwards along the clamping groove, allowing the clamping positioning component to clamp the motor equipment from multiple directions, thus fixing the motor equipment and simulating its fixed state after being put into use. This ensures stable vibration measurement. Moreover, the clamping structure in this invention can be activated simultaneously when the vibration meter contacts the motor equipment, eliminating unnecessary time spent on positioning the motor equipment.

Detailed Implementation

[0024] To make the objectives, solutions, and advantages of the technical solutions of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments of the present invention.

[0025] Example 1: A vibration measuring device for motor equipment, such as Figure 1-8As shown, it includes: a main support frame 1, with self-locking worm gears A101 on the top left and right sides of the main support frame 1; an installation angle adjustment shaft 102 is rotatably mounted on the inner side of the main support frame 1, the installation angle adjustment shaft 102 is set to facilitate the installation of the self-locking worm gear A103 and the installation angle adjustment component 2; the installation angle adjustment shaft 102 has a cylindrical structure; self-locking worm gears A103 are set on the left and right sides of the installation angle adjustment shaft 102, the self-locking worm gears A103 are set to facilitate cooperation with the self-locking worm gears A101 to achieve self-locking of the installation angle adjustment shaft 102; the self-locking worm gears A103 are connected to the self-locking worm gears A101; guide components 104 are set on the left and right sides of the main support frame 1, guiding... The guide member 104 is designed to guide the guide slide rod 2020 and the test platform 201 during rotation; the guide member 104 has an arc-shaped structure; an installation angle adjustment member 2 is positioned centrally on the installation angle adjustment shaft 102, and the installation angle adjustment member 2 is designed to facilitate the installation of the test platform 201; the test platform 201 is positioned at the outer end of the installation angle adjustment member 2, and the test platform 201 is designed to facilitate the installation of the output angle horizontal rotation shaft 203 and the self-locking worm gear B202; the test platform 201 has an internal mounting groove, and the self-locking worm gear B202 is installed inside the mounting groove; the output angle horizontal rotation shaft 2020 is rotatably mounted at the central position of the top of the test platform 201. 3. The output angle horizontal rotating shaft 203 has a cylindrical structure; a self-locking worm gear B204 is installed on the output angle horizontal rotating shaft 203; the self-locking worm gear B204 is connected to the self-locking worm wheel B202. After performing a vibration test on the motor equipment with planar installation, the installation angle of the motor equipment is changed by manually rotating the test platform 201, the clamping platform 205, and the motor equipment with the installation angle adjustment shaft 102 as the base point. Moreover, when the test platform 201 is no longer manually rotated, the installation angle adjustment shaft 102 can achieve self-locking under the action of the self-locking worm gear A103 and the self-locking worm wheel A101, positioning the test platform 201, the clamping platform 205, and the motor equipment in the adjusted position. The angle is adjusted to facilitate vibration testing of motor equipment at different installation angles. When vibration testing of motor equipment at different output angles is required, the operating component 207 can be manually turned to make the clamping platform 205 and the motor equipment rotate around the output angle horizontal rotating shaft 203 as the base point, thereby adjusting the output angle of the motor equipment. When the operating component 207 is no longer manually turned, the output angle horizontal rotating shaft 203 can achieve self-locking under the action of the self-locking worm gear B204 and the self-locking worm wheel B202, so that the clamping platform 205 and the motor equipment are positioned at the adjusted angle, which facilitates vibration testing of motor equipment at different output angles.

[0026] Example 2: Based on Example 1, such as Figure 1-8As shown, a clamping platform 205 is provided at the top of the output angle horizontal rotating shaft 203; clamping grooves 206 are arranged in a cross shape on the upper and lower sides of the clamping platform 205; the clamping grooves 206 have an oval structure; an operating component 207 is provided at the front end of the clamping platform 205; the operating component 207 has a U-shaped structure; a clamping driven rod 208 is slidably installed inside the clamping grooves 206; the clamping driven rod 208 has a cylindrical structure; a clamping positioning component 209 is provided at the top of the clamping driven rod 208; the clamping positioning component 209 has a rectangular structure; the clamping platform... A trigger mounting shaft 2010 is centrally located inside the clamping platform 205; the trigger mounting shaft 2010 has a cylindrical structure; a trigger tension plate 2011 is mounted on the trigger mounting shaft 2010; the trigger tension plate 2011 is located inside the clamping platform 205; the trigger tension plate 2011 has a disc-shaped structure; a trigger tension groove 2012 is formed on the top of the trigger tension plate 2011; the trigger tension groove 2012 has an arc-shaped structure; the clamping driven rod 208 is also located inside the trigger tension groove 2012; and a trigger tension plate 2011 has a circumferential outer wall on its surface. A follower gear ring 2013 is provided; the follower gear ring 2013 has a circular structure; an operating support plate 2014 is provided on the top rear side of the clamping platform 205; a stroke groove 2015 is provided on the operating support plate 2014; a stroke slide plate 2016 is provided inside the stroke groove 2015. When the control screw 2018 rotates, the control screw 2018 will drive the drive gear 2019 to rotate. Since the drive gear 2019 meshes with the follower gear ring 2013, the rotation of the drive gear 2019 will engage with the follower gear ring 2013. When the trigger pull plate 2011 rotates, the clamping driven rod 208 is located inside the trigger pull groove 2012. The trigger pull groove 2012 will use its own arc structure to start pulling the clamping driven rod 208 and the clamping positioning member 209 inward along the clamping slide 206. This causes the clamping driven rod 208 and the clamping positioning member 209 to clamp and fix the motor equipment from multiple directions by moving inward, simulating the fixed state of the motor equipment after it is put into normal use, thus improving the realism of the simulation of this vibration measuring device.

[0027] Example 3: Based on Example 2, such as Figure 1-8As shown, a motor vibration meter 2017 is installed at the inner end of the travel slide plate 2016; a control screw 2018 is installed on the rear side of the operating support plate 2014; an operating disc is installed at the top of the control screw 2018; the control screw 2018 is connected to the travel slide plate 2016 via threads; a drive gear 2019 is installed on the outer circumference of the control screw 2018; the drive gear 2019 meshes with the follower gear ring 2013; guide slide rods 2020 are installed on the left and right sides of the test platform 201; the guide slide rods 2020 are also slidably installed inside the guide member 104; when the control screw 2018 rotates, it will use threads to drive the travel slide plate 2016 and the motor vibration meter 2017 to move along the travel groove 2015; when the control screw 2018 rotates, it will also drive... The gear 2019 drives the follower gear ring 2013 and the trigger tension plate 2011 to rotate. When the trigger tension plate 2011 drives the trigger tension groove 2012 to rotate, the trigger tension groove 2012 will pull the clamping driven rod 208 inward along the clamping slide groove 206. By manually rotating the operating plate on the control screw 2018, the operating plate drives the control screw 2018 to rotate. The control screw 2018 uses the rotation to drive the travel slide plate 2016 to move downward along the travel slide groove 2015. This causes the travel slide plate 2016 to drive the motor equipment vibration meter 2017 to descend, so that the vibration measuring end of the motor equipment vibration meter 2017 can contact the motor equipment due to the descent. Thus, through the contact between the motor equipment vibration meter 2017 and the motor equipment, the motor equipment vibration meter 2017 can effectively detect the vibration force of the motor equipment during operation.

[0028] The specific usage and function of this embodiment are as follows: In use, the motor equipment is first placed on the horizontal clamping platform 205. Then, the operating disc on the control screw 2018 is manually rotated, causing the control screw 2018 to rotate. This rotation causes the control screw 2018 to move the travel slide plate 2016 downwards along the travel groove 2015. The travel slide plate 2016 then lowers the vibration meter 2017, allowing the vibration measuring end of the vibration meter 2017 to contact the motor equipment. Furthermore, when the control screw 2018 rotates, it drives the drive gear 2019 to rotate. Since the drive gear 2019 meshes with the follower gear ring 2013, its rotation will... The follower gear ring 2013 works in conjunction with the trigger tension plate 2011 to rotate. When the trigger tension plate 2011 rotates, the clamping driven rod 208 is located inside the trigger tension groove 2012. The trigger tension groove 2012 will use its own arc structure to start pulling the clamping driven rod 208 and the clamping positioning piece 209 inward along the clamping slide 206. This causes the clamping driven rod 208 and the clamping positioning piece 209 to clamp and fix the motor equipment from multiple directions by moving inward, simulating the fixed state of the motor equipment after it is put into normal use. This improves the realism of the simulation of this vibration measuring device. This completes the fixing of the motor equipment. Then the motor equipment is started and put into operation. During the operation, the motor equipment vibration meter 2017 can detect the vibration of the motor equipment during operation. After performing a vibration test on the motor equipment with planar installation, the installation angle of the motor equipment is changed by manually rotating the test platform 201, clamping platform 205, and motor equipment with the installation angle adjustment shaft 102 as the base point. When the test platform 201 is no longer manually rotated, the installation angle adjustment shaft 102 self-locks under the action of the self-locking worm gear A103 and self-locking worm wheel A101, positioning the test platform 201, clamping platform 205, and motor equipment at the adjusted angle. This facilitates vibration testing of the motor equipment at different installation angles. Simultaneously, the operating component 2 can be manually manipulated. 07. The operating component 207 drives the clamping platform 205 and the motor equipment to rotate around the output angle horizontal rotating shaft 203 as the base point to adjust the output angle of the motor equipment. When the operating component 207 is no longer manually moved, the output angle horizontal rotating shaft 203 can achieve self-locking under the action of the self-locking worm gear B204 and the self-locking worm wheel B202, so that the clamping platform 205 and the motor equipment are positioned at the adjusted angle, which facilitates vibration testing of the motor equipment at different output angles. After the adjustment is completed, the motor equipment is restarted, and the motor equipment vibration meter 2017 measures the vibration of the motor equipment after the angle is adjusted.
