In addition, the reducer must pass dynamic inspection before leaving the factory. The conventional reducer test bench is a straight-line layout, which is not convenient for docking with the assembly line, or the assembly line passes through the middle of the test bench, resulting in a split layout of the test bench. Utility Model Content
[0003] 1. Technical issues to be resolved
[0004] In view of the deficiencies in the prior art, the utility model provides a test platform for a speed reducer with load, which solves the problems raised in the above-mentioned background technology.

[0008] Preferably, the driving motor and the reduced gear being tested are fixed on the feed and discharge slide plate through auxiliary tooling, wherein the motor shaft of the driving motor is connected to the input end of the reduced gear being tested, and the output end of the reduced gear being tested is at the same height and parallel to the transmission half shaft.
[0009] Preferably, the brake, reducer, torque sensor and transmission half shaft are all connected together and rotate synchronously, the torque sensor can detect the rotational torque, the brake can apply rotational resistance, and the reducer is used to amplify the detection range of the load.
[0010] Preferably, when the servo motor is working, it can drive the feed and discharge slide to move back and forth on the feed and discharge guide rail through the screw module. The reducer to be tested is put in when the feed and discharge slide moves to the front end, and when the feed and discharge slide moves to the rear end, the output end of the reducer to be tested is concentric with the transmission half shaft.
[0011] Preferably, when the test cylinder is working, it can push the test slide to make a short distance reciprocating motion on the test guide rail.

[0012] The utility model provides a test platform for a reducer with load, which has the following beneficial effects:
[0013] 1. The reducer load test platform, through the coordinated setting of T-type machine tool, detection slide plate and feed-in and feed-out guide rail, makes the reducer load test platform have the effect of convenient docking with the assembly line. The traditional straight-line machine tool is changed to a T-type machine tool structure with three forks. The added fork is used for docking with the assembly line, and then the reciprocating motion of the detection slide plate on the feed-in and feed-out guide rail is used to realize the transmission of the tested reducer between the assembly line and the test structure, thereby realizing convenient docking with the assembly line.
[0014] 2. The reducer load test platform, through the coordinated setting of the T-type machine tool, the feed and discharge guide rails and the feed and discharge slide plates, makes the reducer load test platform have the effect of becoming an independently working station, which is not only convenient for transportation but also suitable for various application scenarios. By adding a branch as a T-type machine tool structure for transporting the tested reducer, the test platform can be installed on the side of the assembly line as a whole, instead of being made into two sections symmetrically installed on both sides of the assembly line for the convenience of testing the products on the assembly line like the traditional one-shaped machine tool. Since this test platform is an independent station, it can also work independently from the assembly line and then manually load materials, so it can be suitable for various application scenarios.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0019] See also Figure 2 The utility model provides a technical solution: a test platform for a reducer with load, comprising a T-type machine tool 1, a test guide rail 2 and an inlet and outlet guide rail 3 are installed above the T-type machine tool 1, the T-type machine tool 1 is installed on the side of the production line and the rear end of the inlet and outlet guide rail 3 is docked with the production line, test cylinders 4 are installed at both ends of the test guide rail 2, a detection slide plate 5 pushed by the test cylinder 4 is installed above the test guide rail 2, a brake 6, a reducer 7, a torque sensor 8 and a transmission half shaft 9 are installed above the detection slide plate 5 from the outer end to the inner end, the brake 6, the reducer 7, the torque sensor 8 and the transmission half shaft 9 are all connected together and rotate synchronously, and the torque The sensor 8 can detect the rotational torque, the brake 6 can apply the rotational resistance, the reducer 7 is used to amplify the detection range of the load, a screw module 10 is installed in the middle of the feed and discharge guide rail 3, a servo motor 11 is installed at one end of the screw module 10, and a feed and discharge slide 12 driven by the screw module 10 is installed above the feed and discharge guide rail 3. One end of the feed and discharge guide rail 3 is inserted into the middle position of the test guide rail 2. The feed and discharge guide rail 3 is perpendicular to the test guide rail 2. The length of the feed and discharge guide rail 3 is greater than twice that of the feed and discharge slide 12, so that when the feed and discharge slide 12 moves to the outer end of the feed and discharge guide rail 3, both sides are no longer disturbed by the detection structure, which can facilitate docking with the production line. In order to facilitate the picking and placing of products, a driving motor 13 and a tested reducer 14 are arranged above the feeding and discharging slide 12. The driving motor 13 and the tested reducer 14 are fixed on the feeding and discharging slide 12 through auxiliary tooling. The specific structure of the tooling is determined according to the structural size of the tested reducer 14. The output torque of the driving motor 13 is determined according to the torque required for the detection of the tested reducer 14. The motor shaft of the driving motor 13 is connected to the input end of the tested reducer 14, and the output end of the tested reducer 14 is at the same height and parallel to the transmission half shaft 9. The servo motor When 11 is working, the feed and discharge slide 12 can be driven by the screw module 10 to move back and forth on the feed and discharge guide rail 3. The tested reducer 14 is put in when the feed and discharge slide 12 moves to the front end. When the feed and discharge slide 12 moves to the rear end, the output end of the tested reducer 14 is concentric with the transmission half shaft 9. When the test cylinder 4 is working, it can push the detection slide 5 to make a short distance reciprocating motion on the test guide rail 2. When the detection slide 5 moves outward, the transmission half shaft 9 does not hinder the forward and backward movement of the detection slide 5. When the detection slide 5 moves inward, the transmission half shaft 9 is connected with the output end of the tested reducer 14.
[0020] When in use, the test platform is docked to the side of the assembly line, that is, the outer end of the feed and discharge guide rail 3 is close to the assembly line or inserted into the interior of the assembly line, so that the tested reducer 14 of the assembly line can be moved by a manipulator or manually at a close distance to the feed and discharge slide 12 that has been retreated to the front end of the feed and discharge guide rail 3. Regardless of whether it is fixed manually or by a manipulator, the input end of the tested reducer 14 needs to be connected to the rotating shaft of the drive motor 13 when the tested reducer 14 is placed. Further, the servo motor 11 works to drive the feed and discharge slide 12 to move to the front end of the feed and discharge guide rail 3 through the screw module 10. At this time, the output end of the tested reducer 14 is required to be concentric with the transmission half-shaft 9. Further, the test cylinder 4 works to push the detection slide 5 inward so that the transmission half-shaft 9 is docked with the output end of the tested reducer 14. The docking method of the transmission half-shaft 9 and the tested reducer 14 needs to be made according to the specific situation. For example, when the output end of the tested reducer 14 is a hole with a groove, the transmission half-shaft 9 can be The shaft inserted into the hole and connected by the key further drives the motor 13 to work and output the load and speed required for detecting the tested reducer 14, and then applies reverse resistance to the transmission half shaft 9 through the braking function of the brake 6, so that the tested reducer 14 works under a specific torque to realize the load test. After the load test is completed, the test cylinder 4 works to pull the detection slide plate 5 back to the outside so that the transmission half shaft 9 is separated from the output end of the tested reducer 14, and further the servo motor 11 works to drive the feed and discharge slide plate 12 to move to the rear end of the feed and discharge guide rail 3 through the screw module 10, that is, the tested reducer 14 that has been tested is sent to the assembly line, and further the tested reducer 14 that has been tested is moved back to the assembly line manually or by a robot and a new untested tested reducer 14 is placed. Since the test platform is not structurally connected to the assembly line, the test platform can be separated and can be used independently or spliced with the assembly line according to actual conditions, thereby making it more practical.
[0021] To sum up, the reducer load-adding test platform is modified from the traditional straight-line machine tool to a T-type machine tool 1 structure with three forks, and the added fork is used to dock with the assembly line, and then the reciprocating motion of the detection slide 5 on the feed and discharge guide rail 3 is used to realize the transmission of the tested reducer 14 between the assembly line and the test structure, thereby facilitating the docking with the assembly line. By adding a fork as the T-type machine tool 1 structure for transporting the tested reducer 14, the test platform can be installed on the side of the assembly line as a whole, instead of being made into two sections symmetrically installed on both sides of the assembly line for the convenience of testing the products on the assembly line as with the traditional straight-line structure machine tool. Since the test platform is an independent workstation, it can also be separated from the assembly line to work independently and then manually loaded, and can be suitable for various application scenarios.
[0022] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
