[0002] Motor products require numerous tests during production, such as tests on rotor commutator resistance and overvoltage. Current testing equipment for motor products connects a single testing component to the output of a corresponding linear drive mechanism.

This rotation, combined with the movement of the testing component, allows the component to inspect multiple parts of the motor sequentially. This testing structure is highly inefficient, prone to inaccurate positioning, and easily leads to false readings.

[0003] Therefore, it is necessary to provide a test clamping mechanism for motor products to solve the above-mentioned technical problems. Utility Model Content

[0025] Existing testing equipment for motor products connects a single testing component to the output of a corresponding linear drive mechanism. The rotation of the motor product coordinates with the movement of the testing component, allowing the testing component to test multiple parts of the motor product one by one. The number of tests is the same as the number of parts that need to be tested on the motor product, requiring multiple testing steps. This testing method is very inefficient and inaccurate, easily leading to false tests.

[0026] The following is a preferred embodiment of a test clamping mechanism for motor products provided by this utility model, which can solve the above-mentioned technical problems.

[0027] Please refer to Figure 1 and Figure 2 In the diagram, units with similar structures are represented by the same labels.

[0028] This embodiment provides a test clamping mechanism for motor products, comprising: a fixing plate 11, a detection component 12, a sensor 13, a clamp 14, a rotary drive assembly 15, and a detection drive assembly 16. The motor product in this invention can be a motor rotor 151. The clamp 14 holds the motor rotor 151, and the detection component 12 tests parameters such as the resistance and overvoltage of the rotor commutator.

[0029] Please refer to Figure 1 The clamp 14 passes through the fixed plate 11 and forms a rotatable connection. The clamp 14 is used to clamp the motor product. Multiple detection components 12 are slidably disposed on one side of the fixed plate 11 and surround the clamp 14. The clamp 14 is located in the sliding direction of the detection components 12. The sensor 13 is fixedly disposed on one side of the fixed plate 11, and the sensing direction of the sensor 13 is towards the motor product clamped by the clamp 14. In this embodiment, the sensor 13 can be a laser sensor. Each time the motor product rotates to the corresponding detection state, there is a corresponding mark (mark, such as a through hole) on the motor product for the sensor 13 to detect. The sensor 13 can be used to detect whether the clamp 14 is clamping the motor product, and also to detect whether the rotation angle of the motor product is in place, so that the detection component 12 can accurately contact the detection part of the motor product to perform the corresponding detection work.

[0030] The rotary drive assembly 15 and the detection drive assembly 16 are fixedly mounted relative to the fixed plate 11. The output end of the rotary drive assembly 15 is connected to the clamp 14, which drives the motor product held by the clamp 14 to rotate, allowing the motor product to rotate and switch different parts to dock with the detection component 12. The output end of the detection drive assembly 16 is connected to multiple detection components 12, which drives the detection components 12 to slide, allowing the detection components 12 to contact or detach from the motor product.

[0031] Please refer to Figure 2 and Figure 4 In this embodiment, the test clamping mechanism for motor products also includes a clamping body 17, and the clamping body 17 and the fixing plate 11 are connected by a connecting plate group 18.

[0032] The clamp 14 includes a sleeve rod 141, an elastic chuck 143, a control rod 142, and a clamping drive assembly connected to the mold clamping body 17.

[0033] Please refer to Figure 4The sleeve rod 141 passes through the locking body 17 and the fixing plate 11, forming a rotatable connection. The elastic chuck 143 is in an open state under its own elastic force, so that the motor product can be placed into the elastic chuck 143. The elastic chuck 143 is sleeved on the end of the sleeve rod 141 near the fixing plate 11. The control rod 142 is slidably disposed in the sleeve rod 141. One end of the control rod 142 is connected to the elastic chuck 143, and the other end of the control rod 142 is connected to the output end of the clamping drive assembly. When the control rod 142 drives the elastic chuck 143 to slide inward to the inside of the sleeve rod 141, the sleeve rod 141 can squeeze the elastic chuck 143 to retract so as to clamp the motor product.

[0034] Please refer to Figure 2 The rotary drive assembly 15 includes a motor 151, a first pulley 152, a second pulley 153, and a belt. The first pulley 152 is connected to the output end of the motor 151, and the second pulley 153 is fixedly sleeved on the outer circumference of the sleeve rod 141. The first pulley 152 and the second pulley 153 are connected by a belt drive, thereby enabling the motor 151 to drive the sleeve rod 141 to rotate. The motor 151 is located at the top of the clamping body 17, which allows it to be well offset from the clamping drive assembly.

[0035] Please refer to Figure 2 In this embodiment, the clamping drive assembly includes a clamping cylinder 144 and a connecting rod 145. One end of the clamping body 17 is provided with an extension rod 171. One end of the connecting rod 145 is rotatably connected to the extension rod 171, and the other end of the connecting rod 145 is rotatably connected to the output end of the clamping cylinder 144. A transmission hole is provided in the middle of the connecting rod 145, and a connecting seat 146 is provided on the inner wall of the transmission hole. A transmission bearing 147 is sleeved on the outer periphery of the control rod 142, located within the transmission hole, and is tractively connected to the connecting seat 146. Thus, the clamping cylinder 144 can stably drive the control rod 142 to slide via the connecting rod 145, thereby controlling the elastic chuck 143 to clamp the motor product.

[0036] Please refer to Figure 4 Additionally, a retaining ring 148 is provided on the outer periphery of the control rod 142 to limit the transmission bearing 147. The transmission bearing 147 is provided between the connecting rod 145 and the control rod 142. When the sleeve rod 141 drives the motor product to rotate through the elastic clamp 143, the control rod 142 can also rotate together without affecting the connection between the control rod 142 and the connecting rod 145.

[0037] Please refer to Figure 2In this embodiment, the connecting plate assembly 18 includes a first connecting plate 181 and a second connecting plate 182. One end of the first connecting plate 181 and one end of the second connecting plate 182 are slidably and adjustablely connected. The other end of the first connecting plate 181 is fixedly connected to the mold-locking body 17, and the other end of the second connecting plate 182 is fixedly connected to the fixing plate 11. This allows the connection position between the first connecting plate 181 and the second connecting plate 182 to be adjusted, changing the distance between the fixing plate 11 and the mold-locking body 17. This, in turn, adjusts the distance by which the elastic clamp 143 extends beyond the fixing plate 11, enabling the elastic clamp 143 to hold motor products of different specifications for contact testing with the detection component 12.

[0038] Please refer to Figure 1 and Figure 3 In this embodiment, a sliding groove 111 is provided through the fixed plate 11, and the detection component 12 is slidably connected to the sliding groove 111 via a slider 121. A connecting post 1211 for connecting with the detection drive component 16 is provided on the slider 121.

[0039] The detection drive assembly 16 includes a detection control cylinder 161, a locking pin disc 162, and a lever 163.

[0040] The locking needle disc 162 is located on the side of the fixing plate 11 away from the detection component 12. The locking needle disc 162 is rotatably sleeved on the outer periphery of the sleeve rod 141. Multiple transmission grooves 1621 are provided on the locking needle disc 162 around the central axis of the sleeve rod 141. The connecting column 1211 is fitted in the transmission groove 1621. The detection control cylinder 161 is fixedly connected to the fixing plate 11. The lever 163 connects the output end of the locking needle disc 162 and the detection control cylinder 161, so that the detection control cylinder 161 can drive the locking needle disc 162 to rotate through the lever 163, thereby driving multiple detection components 12 to slide synchronously.

[0041] More specifically, the output end of the detection and control cylinder 161 is a telescopic rod 1611 with a connecting hole, and the connecting hole passes through the telescopic rod 1611 radially.

[0042] A bushing 164 is fixedly connected to the side of the locking pin disc 162 away from the fixing plate 11. The bushing 164 is rotatably sleeved on the outer circumference of the sleeve rod 141. A lever 163 is fixedly sleeved on the outer circumference of the bushing 164. A connecting rod 1631 is provided on one side of the lever 163. The connecting rod 1631 is connected to a connecting hole. An elongated through hole 1632 is provided on the connecting rod 1631. A linkage post is provided in the connecting hole. The linkage post is movably fitted in the elongated through hole 1632. In this way, the extension and retraction of the telescopic rod 1611 can stably drive the locking pin disc 162 to rotate.

[0043] In this embodiment, a limiting block 165 is fixedly installed on the fixing plate 11. The limiting block 165 is located on the extension and retraction trajectory of the telescopic rod 1611. The extension and retraction stroke of the telescopic rod 1611 is limited by the limiting block 165, thereby precisely controlling the rotation angle of the locking pin disc 162, so that the detection component 12 can accurately contact the motor product.

[0044] Alternatively, the limitation on the extension stroke of the telescopic rod 1611 can be adjusted by replacing the limit block 165 with one of different thicknesses or by sliding and adjusting the connection position of the limit block 165.

[0045] In this embodiment, the sensor 13 is connected to the fixed plate 11 via a mounting plate 131. The mounting plate 131 has an L-shaped structure and is provided with an elongated hole for connecting to the fixed plate 11. The extension direction of the elongated hole is perpendicular to the fixed plate 11. By sliding and adjusting the connection position of the mounting plate 131, the sensing position of the sensor 13 on the motor product can be changed.

[0046] The working principle of this utility model is as follows: When it is necessary to test the motor product, the clamping cylinder 144 first slides through the drive control rod 142 of the connecting rod 145. The control rod 142 pushes the elastic chuck 143 to slide out of the sleeve rod 141. Under its own elastic force, the elastic chuck 143 is in an open state, at which time the motor product can be placed into the elastic chuck 143. Then, the clamping cylinder 144 is driven to retract into the sleeve rod 141. The sleeve rod 141 can squeeze the elastic chuck 143 to contract, so that the elastic chuck 143 clamps the motor product.

[0047] Then, the sensor 13 senses the motor product to determine whether the detection component 12 is aligned with the detection part of the motor product. If the alignment is good, the detection control cylinder 161 drives the locking pin disk 162 to rotate through the lever 163, thereby driving multiple detection components 12 to slide synchronously towards the motor product, so as to realize the detection work of the detection component 12 on the motor product.

[0048] After the detection component 12 completes the detection of a portion of the motor product, the motor 151 drives the sleeve rod 141 and the elastic clamp 143 to rotate at a set angle according to a preset program, so that the other parts to be detected on the motor product are aligned with the detection component 12. Similarly, after the alignment is completed, the detection control cylinder 161 drives the locking pin plate 162 to rotate through the lever 163, thereby driving multiple detection components 12 to slide synchronously towards the motor product, realizing a new round of detection work of the detection component 12 on the motor product, until all the parts to be detected on the motor product have been detected.

[0049] It should be noted that the number of detection components 12 can be equal to the number of parts to be detected on the motor product, or the number of parts to be detected on the motor product can be an integer multiple of the number of detection components 12.

[0050] This completes the testing process of the motor product by the test clamping mechanism of this preferred embodiment.

[0051] The preferred embodiment of the test clamping mechanism for motor products uses a rotary drive component to drive the fixture to rotate, and a detection drive component to drive multiple detection components to slide. This enables precise positioning of the motor product, facilitates testing of the motor product, and the multiple detection components result in high testing efficiency and greatly reduce false tests.

[0052] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
