[0002] In the production and testing of heater motors, the clamping fixture is a key component connecting the motor and the testing equipment, and its performance directly affects the testing accuracy and efficiency.

[0003] Traditional tooling often uses fixed clamps or simple manual adjustment structures. For heater motors of different sizes and interface positions, it is necessary to frequently change clamps or manually adjust the clamping position. The clamping time is too long, which is time-consuming and labor-intensive, and thus reduces the overall testing efficiency of the heater motor. Utility Model Content

Two clamping assemblies are symmetrically arranged on both sides of the clamping platform. Each clamping assembly includes a slot, a positioning seat, and a pushing assembly. The pushing assembly is fixed on both sides of the clamping platform. The positioning seat is located inside the slot and is slidably connected to the slot. The output end of the pushing assembly is provided with a push rod connected to the positioning seat. The upper end of the positioning seat is provided with a guide rail. Two movable seats are symmetrically arranged on the guide rail and are slidably connected to the guide rail. One end of the positioning seat is provided with a drive motor. The output end of the drive motor is provided with a rotating shaft. Two threaded rods with reverse thread structure are symmetrically arranged on the rotating shaft. The two threaded rods pass through the two movable seats and are threadedly connected to the movable seats. The upper end of the movable seat is provided with a support rod. Two clamping blocks are symmetrically arranged at the clamping end of the support rod.

[0006] Furthermore, the improvements of this utility model include the use of cylinders for both the lifting assembly and the propulsion assembly, and the use of servo motors for both of the drive motors.

[0007] To improve the stability of the movable seat during movement, the present invention includes an improvement whereby the movable seat is provided with a guide groove through which a guide rail passes, and the cross-section of the guide groove is T-shaped.

[0008] Furthermore, an improvement of this utility model is that the plurality of clamping blocks are of the same size and are all cylindrical structures, and the clamping blocks are provided with rubber anti-slip sleeves.

[0009] (III) Beneficial Effects Compared with the prior art, this utility model provides a whole-machine testing fixture for a heater motor, which has the following beneficial effects: Compared to traditional tooling that requires frequent fixture changes or manual adjustment of clamping positions, this clamping tooling automates height adjustment, initial clamping, and adaptive clamping operations via a controller. From motor placement to clamping completion, the entire process is significantly faster, offering greater convenience and shorter operation.

[0010] This structure can accommodate the clamping needs of heater motors of different sizes without the need to change clamps. Whether it is a small household heater motor or a large industrial heater motor, it can be stably clamped by adjusting the spacing of the clamping blocks through the drive motor, which expands the applicability of the tooling, reduces the cost of equipping multiple toolings due to different motor sizes, and improves resource utilization.

[0012] 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.

[0013] Please see Figure 1-4The present invention provides a whole machine testing clamping fixture for a heater motor, including a clamping platform 1, a cavity 2 in the middle part of the clamping platform 1, a support plate 3 inside the cavity 2, a lifting assembly 4 below the clamping platform 1, and a lifting rod connected to the support plate 3 at the output end of the lifting assembly 4. Two clamping assemblies are symmetrically arranged on both sides of the clamping platform 1. Each clamping assembly includes a slot 5, a positioning seat 6, and a pushing assembly 16. The pushing assembly 16 is fixed on both sides of the clamping platform 1. The positioning seat 6 is located inside the slot 5 and is slidably connected to the slot 5. The output end of the pushing assembly 16 is provided with a push rod connected to the positioning seat 6. The upper end of the positioning seat 6 is provided with a guide rail 9. Two movable seats 10 are symmetrically arranged on the guide rail 9 and are slidably connected to the guide rail 9. One end of the positioning seat 6 is provided with a drive motor 13. The output end of the drive motor 13 is provided with a rotating shaft 14. Two threaded rods 15 with reverse thread structure are symmetrically arranged on the rotating shaft 14. The two threaded rods 15 pass through the two movable seats 10 respectively and are threadedly connected to the movable seats 10. The upper end of the movable seat 10 is provided with a support rod 11. Two clamping blocks 12 are symmetrically arranged at the clamping end of the support rod 11.

[0014] In this embodiment, both the lifting component 4 and the propulsion component 16 are cylinders, and both drive motors 13 are servo motors.

[0015] Height Adjustment Principle: When using this clamping fixture, first place the heater motor to be clamped onto the tray 3 inside the central cavity 2 of the clamping platform 1. The lifting assembly 4 below the clamping platform 1 then comes into play. Since the lifting assembly 4 uses a cylinder, by operating the controller on the clamping platform 1, the lifting assembly 4 is activated, and the output end of the lifting assembly 4, i.e., the lifting rod, will push the tray 3 up or down. In this way, the height of the tray 3 can be precisely adjusted according to the testing requirements, so that the heater motor is at the specified height position, preparing for subsequent clamping operations.

[0016] Initial clamping principle: After the heater motor is placed at a suitable height, the propulsion assembly 16 is activated. The propulsion assembly 16 also uses a cylinder. The propulsion assembly 16, which is fixed on both sides of the clamping platform 1, works, and the push rod at its output end pushes the positioning seat 6 to slide in the slot 5. As the positioning seat 6 moves, the moving seat 10 on the upper guide rail 9 of the positioning seat 6, as well as the support rod 11 and clamping block 12 connected to the moving seat 10, also move, so that the multiple clamping blocks 12 gradually approach the heater motor, and initially clamp the heater motor.

[0017] Adaptive clamping principle: When encountering heater motors of different sizes, the adaptive adjustment function of the clamping fixture is activated. The drive motor 13 at one end of the positioning seat 6 is a servo motor. After the drive motor 13 is started, the rotating shaft 14 at its output end rotates. Since two threaded rods 15 with reverse thread structure are symmetrically arranged on the rotating shaft 14, and the two threaded rods 15 pass through the two moving seats 10 respectively and are threadedly connected to the moving seats 10, when the rotating shaft 14 rotates, through the action of the reverse thread structure, the two moving seats 10 will move towards or away from each other along the guide rail 9. In this embodiment, the movable seat 10 is provided with a guide groove through which the guide rail 9 passes, and the cross-section of the guide groove is T-shaped.

[0018] The guide groove has a T-shaped cross-section and cooperates with the guide rail 9 to prevent the movable seat 10 from shifting or shaking during movement. When the movable seat 10 moves, the support rod 11 connected to its upper end also moves synchronously, thereby adjusting the distance between the two support rods 11 so that the clamping block 12 can fit tightly against heater motors of different sizes, realizing adaptive clamping of heater motors of different sizes without the need to change the clamp or manually adjust the clamping position.

[0019] Anti-slip fixing principle: In this embodiment, the multiple clamping blocks 12 are the same size and are all cylindrical structures, and the clamping blocks 12 are provided with rubber anti-slip sleeves.

[0020] Throughout the clamping process, the clamping blocks 12 play a crucial role in securing the motor. Multiple clamping blocks 12 are identical in size and all have a cylindrical structure with rubber anti-slip sleeves on their surfaces. The cylindrical structure of the clamping blocks 12 allows for better contact with the motor surface, while the rubber anti-slip sleeves increase the friction between the clamping blocks 12 and the motor, effectively preventing the motor from slipping or shifting during testing, thus ensuring the accuracy and stability of the test.

[0021] Improved clamping efficiency: Compared to traditional tooling that requires frequent fixture changes or manual adjustment of clamping positions, this clamping tooling automates height adjustment, initial clamping, and adaptive clamping operations via a controller. From placing the motor to completing the clamping process, the entire time is significantly reduced, making it more convenient and efficient.

[0022] Enhanced applicability: It can adapt to the clamping requirements of different sizes of heater motors without the need to change clamps. Whether it is a small household heater motor or a large industrial heater motor, it can be stably clamped by adjusting the spacing of the clamping blocks 12 through the drive motor 13, which expands the applicability of the tooling, reduces the cost of equipping multiple toolings due to different motor sizes, and improves resource utilization.

[0023] The lifting assembly 4, the propulsion assembly 16, and the drive motor 13 are centrally controlled via multiple switches on the controller. Operators can easily complete the clamping operation without requiring complex skills, reducing labor intensity and technical barriers, and improving work efficiency. In this whole-machine testing clamping fixture for the warm air motor, the controller, as the core control component, undertakes the task of precisely controlling the lifting assembly 4, the propulsion assembly 16, and the drive motor 13, ensuring the efficient and stable operation of the clamping fixture. Its principle is mainly based on electrical control principles and signal transmission mechanisms.
