Detailed implementation mode

[0032] This application provides a device for detecting the quick clamping performance of a motor gearbox.

[0033] Embodiment 1:

[0034] Refer to Figure 1 , a device for detecting the quick clamping performance of a motor gearbox includes: a support frame 1, a motor 3, a gearbox 4, and a detection component 6 on a detection plate 2. The detection plate 2 is fixedly installed on the support frame 1 by bolts. The output shaft of the motor 3 is connected to the gearbox 4. An installation component 5 is arranged between the gearbox 4 and the detection plate 2. The installation component 5 can quickly install the gearbox 4 onto the detection plate 2 so that the detection component 6 can detect whether there is abnormal noise in the gearbox 4, thereby improving the detection efficiency; during detection in the embodiment of this application, it can be detected in a soundproof booth.

[0035] Refer to Figure 1 , the installation component 5 includes: a positioning pin 51. In the embodiment of this application, there are three positioning pins 51, and three positioning holes 41 corresponding to the positioning pins 51 one by one are provided on the gearbox 4; one end of the positioning pin 51 is fixed on the side wall of the detection plate 2, and the other end is arranged in the positioning hole 41. During installation, align the positioning hole 41 on the gearbox 4 with the positioning pin 51, and move the gearbox 4 until the positioning pin 51 penetrates the positioning hole 41 to complete the preliminary installation of the gearbox 4 and can realize the positioning of the position of the gearbox 4, thereby facilitating detection.

[0036] Refer to Figure 1, Further, the mounting assembly 5 further includes: a fixing plate 52, a mounting plate 53, a pressing rod 54, a pressing head 55, and a locking bolt 56. The fixing plate 52 is fixedly mounted on the detection plate 2, and the mounting plate 53 is mounted on the fixing plate 52 by bolts. One end of the pressing rod 54 passes through the mounting plate 53 and the other end is fixedly connected to the pressing head 55, and the pressing head 55 presses against the gearbox 4. The locking bolt 56 is threadedly sleeved on the pressing rod 54, and the locking bolt 56 abuts against the side wall of the mounting plate 53. After the preliminary installation of the gearbox 4 is completed, the pressing rod 54 is moved until the pressing head 55 presses tightly against the gearbox 4; then, the locking bolt 56 is turned until the locking bolt 56 abuts against the mounting plate 53, so as to press the gearbox 4 tightly, so that the gearbox 4 is not prone to movement, thereby improving the stability of detection.

[0037] See Figure 1 and Figure 2 , The detection assembly 6 includes: a detection rod 61, a swing plate 62, and a counterweight 63. A rotation hole 21 and a connection hole 22 are formed through the side wall of the detection plate 2, and the connection hole 22 is located on the side of the rotation hole 21 close to the gearbox 4; one end of the detection rod 61 is rotatably mounted in the rotation hole 21 and the other end is arranged in the connection hole 22.

[0038] See Figure 1 and Figure 2 , The swing plate 62 is fixed to the bottom wall of the detection rod 61, and the counterweight 63 is sleeved on the swing plate 62. The counterweight 63 mainly plays a role of load. A connection assembly 7 is provided between the detection rod 61 and the output shaft of the gearbox 4. After the gearbox 4 is installed, the connection assembly 7 can automatically and quickly connect the output shaft of the gearbox 4 with the detection rod 61, so as to facilitate the improvement of detection efficiency; and during detection, the motor 3 is started to drive the output shaft of the gearbox 4 to drive the detection rod 61 to rotate forward and backward, so that the swing plate 62 can drive the counterweight 63 to swing; at this time, the gearbox 4 can be listened carefully to determine whether abnormal noises are emitted, so as to detect whether the gearbox 4 has abnormal noises.

[0039] See Figure 2 , Further, scale values are provided on the side wall of the swing plate 62, and the scale values can quantify the position of the counterweight 63, so as to more conveniently facilitate the staff to adjust the position of the counterweight 63.

[0040] See Figure 2 , Further, the detection assembly 6 further includes: a detection wire 64 and a connection head 65. One end of the detection wire 64 is connected to the motor 3 and the other end is connected to the connection head 65. During detection, the current detector can be connected to the connection head 65, and then the current change of the motor 3 is monitored through the current detector to detect whether the current exceeds the allowable range, so as to be able to assist in detecting the gearbox 4 to improve the detection accuracy.

[0041] See Figure 2 As shown in Figure 2 , the connecting component 7 includes a connecting rod 71 and a limiting block 72. A connecting groove 611 is formed at one end of the detecting rod 61 close to the gearbox 4, and a limiting groove 612 is formed on the inner wall of the connecting groove 611. One end of the connecting rod 71 abuts against the output shaft of the gearbox 4, and the other end is arranged in the connecting groove 611. When installing the gearbox 4, the output shaft of the gearbox 4 will be inserted into the connecting hole 22 and abut against the connecting rod 71. Until the installation is completed, the output shaft of the gearbox 4 can abut against the connecting rod 71 tightly to ensure that the output shaft of the gearbox 4 can drive the connecting rod 71 to rotate.

[0042] See Figure 2 As shown in Figure 2 , the limiting block 72 is arranged in the limiting groove 612 and is fixedly connected to the connecting rod 71. When the connecting rod 71 rotates, due to the arrangement of the limiting block 72, the connecting rod 71 is not easy to rotate idly in the connecting groove 611, so that it can drive the detecting rod 61 to rotate together, thereby driving the swing plate 62 to swing to achieve the purpose of detection.

[0043] The working principle of Embodiment 1 is as follows: During installation, align the positioning hole 41 on the gearbox 4 with the positioning pin 51, and move the gearbox 4 until the positioning pin 51 passes through the positioning hole 41 to complete the preliminary installation of the gearbox 4 and achieve the positioning of the position of the gearbox 4, thus facilitating detection.

[0044] Embodiment 2:

[0045] See Figure 3 As shown in Figure 3 , the difference between this embodiment and Embodiment 1 is that a lead screw 621 is rotatably installed on the side wall of the swing plate 62. The lead screw 621 is vertically arranged and passes through the counterweight 63 and is in threaded cooperation with the counterweight 63. Before detection, rotate the lead screw 621 to drive the counterweight 63 to move, so as to change the position of the counterweight 63 (the farther the distance between the counterweight 63 and the detecting rod 61, the greater the force required to drive the detecting rod 61 to rotate; on the contrary, vice versa), to improve the detection accuracy; and at the same time, the counterweight 63 can also be locked so that the counterweight 63 is not easy to move.

[0046] See Figure 3 As shown in Figure 3 , further, a crank 622 is fixedly arranged at the bottom end of the lead screw 621, and the crank 622 can facilitate the staff to rotate the lead screw 621.

[0047] The working principle of Embodiment 2 is as follows: Before detection, hold the crank 622 and rotate it to rotate the lead screw 621, so as to drive the counterweight 63 to move, thereby changing the position of the counterweight 63 to improve the detection accuracy.

[0048] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
