Description

Technical Field

[0001] This utility model relates to the field of speed reducer testing technology, specifically a speed reducer performance testing bench. Background Technology

[0002] The torque transmission test scheme for the speed reducer involves applying a constant load torque to the output end of the speed reducer using a magnetic powder brake. Then, by installing devices such as a servo motor and a speed-changing mechanism on a test bench, the speed reducer placed on the platform is subjected to performance testing.

[0003] A search revealed a patent document CN202221230801.3 that discloses "a speed reducer performance testing platform", which includes: a protective box and a test bench; various testing devices are set on the test bench, and multiple sets of fixing mechanisms are detachably installed on the test bench, which has the advantages of convenient transfer, effective protection of the testing devices, long service life, and simple operation.

[0004] The patent allows for the lifting and lowering of the test bench and its storage inside a protective box to protect the testing device. However, after the test bench is stored, the top of the protective box has an opening, which allows a lot of dust and debris to fall into it when the test bench is not used for a long time, affecting the service life of the internal transmission structure. To address this, we propose a speed reducer performance testing bench to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a speed reducer performance testing platform to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a speed reducer performance testing platform, comprising a support platform, a platform plate, and a side shield. The platform plate is fixedly connected to the top of the support platform, and the side shield is slidably connected to the outer side of the platform plate in a vertical direction. Fixed support plates are welded to both the front and rear sides of the support platform. Two fixed shafts are symmetrically installed on the bottom of the platform plate, and rotating support plates are rotatably connected to the fixed shafts. Baffles are welded to the sides of the bottom of the platform plate corresponding to the fixed shafts. Locking components for fixing are also installed between the two rotating support plates on the same side of the bottom of the platform plate. Inserted sleeves are symmetrically inserted into the top of the side shield, and dustproof folding curtains are fixedly connected between the two inserted sleeves.

[0007] Furthermore, the locking assembly includes a connecting column, which is fixedly installed on the bottom of the platform. A fixing bar is welded to the bottom of the connecting column, and guide grooves are symmetrically opened at both ends of the fixing bar. A locking insert for fixing the rotating support plate is slidably connected in the guide groove.

[0008] Furthermore, a thrust spring is fixedly connected to the side wall of the guide groove, and one end of the thrust spring is fixedly connected to one end of the locking rod.

[0009] Furthermore, one end of the locking rod extends through the outside of the guide groove, and a pull handle is fixedly connected to the surface of the locking rod located outside the fixing bar.

[0010] Furthermore, an anti-vibration pad is adhered to the top of the fixed support plate, specifically a rubber pad.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: When the platform and the testing device on top of it are not in use, as shown in the figure, a rotating support plate supports the device from the bottom of the side shield, which in turn protects the device from the side. Two inserts are inserted into the top of the side shield, and a dustproof folding curtain provides dust protection from above. In the testing state, pulling the handle towards the guide groove causes the locking rod to compress the thrust spring and disengage from the rotating support plate. At this point, with the fixed shaft connected, the rotating support plate can be rotated inwards, disengaging from the support at the bottom of the side shield. The above steps are repeated for each of the four rotating supports. After the plate operation, the side shield will move vertically downwards along the plate direction, separating from the obstruction of the side of the detection component on the top of the plate. It can be supported by the fixed support plate below. This reducer performance testing table has a reasonable structural design and is easy to use. When the reducer performance is being tested, the side protective shield can be moved downwards to facilitate normal operation. When not in use, the side protective shield can protect the testing equipment on the testing table and also provide good dust protection from above, preventing the equipment and testing table from being affected by dust and thus extending their service life. It has excellent performance. Attached Figure Description

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-3 A speed reducer performance testing platform includes a support platform 1, a platform 2, and a side shield 3. The platform 2 is fixedly connected to the top of the support platform 1. The side shield 3 is slidably connected to the outer side of the platform 2 in a vertical direction. A device for testing the speed reducer performance is installed on the top of the platform 2 (not shown in the figure). The side shield 3 can be made of plastic material, which is lightweight and easy to move up and down, while also providing good protection for the testing equipment on the top of the platform 2. Fixed support plates 4 are welded to both the front and rear sides of the support platform 1. When the testing device on the top of the platform 2 is in use, the fixed support plates 4 support the bottom of the side shield 3. At this time, the top plane of the side shield 3 is flush with the top plane of the platform 2, which facilitates operation. An anti-vibration pad 11 is adhered to the top of the fixed support plate 4. The anti-vibration pad 11 is specifically a rubber pad. The anti-vibration pad 11 can prevent hard impact with the top of the fixed support plate 4 when the side shield 3 is lowered. Two fixed shafts 5 are symmetrically installed on the bottom of the platform 2. Rotary connecting rods 5 are mounted on the fixed shafts. A rotating support plate 6 is attached. When the detection device on the top of the platform 2 is not in use, the rotating support plate 6 can be rotated under the connection of the fixed shaft 5 to support the device from the bottom of the side shield 3. At this time, the top plane of the side shield 3 is higher than the top plane of the detection device on the platform 2 to achieve a better protective effect. A baffle 7 is welded to the side of the bottom of the platform 2 corresponding to the fixed shaft 5. The baffle 7 effectively limits the rotation angle of the rotating support plate 6. A locking component 8 is also installed between the two rotating support plates 6 on the same side of the bottom of the platform 2 for fixing. After the rotating support plate 6 is rotated to fit against the baffle 7, the locking component 8 is used to fix the rotating support plate 6, which can effectively improve the stability of the rotating support plate 6 supporting the side shield 3. The top of the side shield 3 is symmetrically inserted with sleeves 9. A dustproof folding curtain 10 is fixedly connected between the two sleeves 9. When the detection device on the platform 2 is not in use, both sleeves 9 are inserted into the top of the side shield 3, and the dustproof folding curtain 10 is used to provide dust protection from the top.

[0016] The locking assembly 8 includes a connecting post 81, which is fixedly installed on the bottom of the platform 2. A fixing bar 82 is welded to the bottom of the connecting post 81. Guide grooves 83 are symmetrically opened at both ends of the fixing bar 82. A locking rod 84 for fixing the rotating support plate 6 is slidably connected in the guide groove 83. By moving the locking rod 84, its end is inserted into the insertion hole on the side of the rotating support plate 6. With the help of the baffle 7, it can be effectively fixed. A thrust spring 85 is fixedly connected to the side wall of the guide groove 83. One end of the thrust spring 85 is fixedly connected to one end of the locking rod 84. The push of the locking rod 84 by the thrust spring 85 ensures the stability of the locking rod 84 inserted into the rotating support plate 6. One end of the locking rod 84 extends through the outside of the guide groove 83. A pull handle 86 is fixedly connected to the surface of the locking rod 84 located outside the fixing bar 82. The pull handle 86 facilitates the lateral pushing and pulling of the locking rod 84.

[0017] This speed reducer performance testing platform has a reasonable structural design and is easy to use. When the speed reducer is being tested, the side protective shields can be lowered to facilitate normal operation. When not in use, the side protective shields can protect the testing equipment on the platform and also provide good dust protection from above, preventing dust from affecting the service life of the equipment and the testing platform. It has excellent performance.

[0018] Working principle: When the platform 2 and the detection device on its top are idle and not in use, as shown in the figure, the rotating support plate 6 is used to support the bottom of the side cover 3, and the side cover 3 provides protection from the side of the detection device. Both plugs 9 are inserted into the top of the side cover 3, and the dustproof folding curtain 10 is used to block dust from above the detection device. In the test use state, the pull handle 86 is pulled towards the guide groove 83, which causes the locking plug 84 to squeeze the push spring 85 and disengage from the rotating support plate 6. At this time, under the connection of the fixed shaft 5, the rotating support plate 6 can be rotated inward and disengaged from the support at the bottom of the side cover 3. After operating the four rotating support plates 6 in sequence using the above steps, the side cover 3 will move vertically downward along the direction of the platform 2, disengaging from the shielding of the side of the detection component on the top of the platform 2, and is then supported by the fixed support plate 4 below.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
