Description

Technical Field

[0001] The utility model relates to the technical field of worm detection, in particular to a special testing device for detecting worm performance. Background Art

[0002] In mechanical engineering, worms are an important transmission element and are widely used in various reducers and transmission mechanisms. In order to ensure that the performance of the worm is stable and reliable in actual work, it is particularly important to accurately test its performance. However, there are some problems with the test devices currently used to test the performance of worms on the market. First, the existing worm test devices often lack an effective fixing mechanism. During the test process, if the worm cannot be firmly fixed, the position and posture of the worm are prone to slight changes, which will directly affect the accuracy of the test results. For example, a slight movement or rotation of the worm may cause deviations in the measurement parameters, thereby affecting the overall performance evaluation. Secondly, most existing test devices lack automatic rotation functions. In the actual test process, it is often necessary to rotate the worm at different angles and directions to fully evaluate its performance. However, most existing test devices require staff to manually flip the worm, which not only increases the labor intensity of the staff, but also makes it difficult to ensure the accuracy and consistency of the rotation, thereby affecting the reliability of the test results.

The bottom of the left support seat 3 is slidably connected to the slide rail 2, and the left support seat 3 can perform horizontal linear sliding in the slide rail 2. The right support seat 3 is arranged at the top of the base 1. The two support seats 3 are rotatably connected with the rotating shaft 4, one end of the rotating shaft 4 is provided with a support plate 9, one side of the support plate 9 is provided with two brackets 5, and a clamping structure 6 is arranged between the two brackets 5. The rotating shaft 4 can drive the clamping structure 6 to rotate through the support plate 9 and the bracket 5. The cylinder 7 is arranged at the top of the base 1, and the driving end of the cylinder 7 is connected to the left support seat 3. The cylinder 7 is used to drive the support seat 3 to move horizontally, and a flip assembly 8 is arranged on the right support seat 3. The flip assembly 8 is used to drive the rotating shaft 4 to rotate.

[0016] Specifically, the clamping structure 6 includes a fixed frame 61, a bidirectional screw 62, a limiting rod 63, two groups of movable seats 64 and two clamping frames 65. The fixed frame 61 is arranged between the two brackets 5. The bidirectional screw 62 is rotatably connected to the left and right sides of the fixed frame 61 respectively. A limiting rod 63 is arranged between the left and right sides in the fixed frame 61. The bidirectional screw 62 and the limiting rod 63 are arranged one up and one down. The two groups of movable seats 64 are movably connected to the left and right sides of the bidirectional screw 62 and the limiting rod 63 respectively. The number of each group of movable seats 64 is two, and the two movable seats 64 are arranged one up and one down. The two clamping frames 65 are respectively arranged between the two groups of movable seats 64, and the two clamping frames 65 are symmetrically arranged on the left and right.

[0017] Specifically, the flip assembly 8 includes a support box 81, a worm 82, a worm wheel 83, a protection box 84 and a motor 85. The support box 81 is arranged on the right support seat 3, the worm 82 is rotatably connected to the left and right sides of the support box 81, the worm wheel 83 is arranged on the rotating shaft 4, and the worm wheel 83 and the worm 82 are meshed. The protection box 84 is arranged on the left side outside the support box 81, the motor 85 is arranged in the protection box 84, and the driving end of the motor 85 is connected to one end of the worm 82.

[0018] Specifically, a handle is provided at one end of the bidirectional screw 62 , and anti-slip grooves are provided on the handle, so that the handle is convenient for the staff to rotate the bidirectional screw 62 .

[0019] Working principle: When the performance of the worm to be tested needs to be tested, first, the staff starts the cylinder 7 to make the driving end of the cylinder 7 contract. This action will cause the left support seat 3 to gradually move away from the right support seat 3, and the distance between the two clamping structures 6 will gradually increase until the distance is greater than the length of the worm to be tested.

[0020] Next, the staff puts the worm to be tested between the two clamping structures 6. At this time, the two ends of the worm to be tested are respectively aligned with the two clamping structures 6. Then, the staff controls the driving end of the cylinder 7 to extend again, and the left support seat 3 gradually approaches the right support seat 3 until the two ends of the worm to be tested are located in the two clamping structures 6.

[0021] In order to ensure the stable fixation of the worm to be detected, the staff will turn the handle. This action will drive the bidirectional screw 62 to rotate. Due to the existence of the limit rod 63, the two sets of moving seats 64 can only move linearly along the direction of the limit rod 63, thereby pushing the two clamping frames 65 to move toward the center of the worm to be detected, and finally the worm to be detected is firmly fixed between the two clamping structures 6.

[0022] After the fixing is completed, the performance test of the worm gear 2 can be started. During this process, the testing device will accurately measure and evaluate various indicators of the worm gear to ensure that it meets the design requirements and usage standards.

[0023] When the worm to be inspected needs to be flipped to perform inspection at different angles or directions, the staff will start the motor 85. The driving end of the motor 85 is connected to the worm 82. When the motor 85 is started, it drives the worm 82 to rotate. Due to the meshing relationship between the worm 82 and the worm wheel 83, the rotation of the worm 82 will further drive the worm wheel 83 to rotate. The worm wheel 83 is connected to the rotating shaft 4, so the rotation of the worm wheel 83 will drive the rotating shaft 4 to rotate together, thereby realizing the flipping of the worm to be inspected.

[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
