Embodiment 1
[0022] Such as figure 1 and figure 2 As shown, this embodiment provides a fixture for testing the welding strength of a motor, which is used to clamp the motor, including a fixture base 1 and a locking bolt 2 .
[0023] Such as figure 2 and image 3 As shown, the housing of the motor includes an upper housing 3 and a lower housing 4 , and the upper housing and the lower housing are respectively connected to a fixing plate 5 .
[0024] Such as figure 1 and image 3 As shown, the cross-section of the fixture seat body is circular, and the fixture seat body extends upwards along the outer peripheral edge to form three fixed columns 6. The three fixed columns are equidistantly distributed, and a clamping space is formed between the three fixed columns. A threaded hole 7 is provided on the top, the motor is placed in the clamping space, and the end of the locking bolt abuts against the side of the motor through the threaded hole.
[0025] Such as figure 1 As shown, there i...

Abstract
The invention discloses a motor welding strength test fixture and a welding strength test method. The test fixture comprises a fixture seat body and a locking bolt, a plurality of fixing columns are arranged on the fixture seat body along the outer periphery, a clamping space is defined by the fixing columns, threaded holes are formed in the fixing columns, the motor is located in the clamping space, and the tail end of the locking bolt abuts against the side face of the motor through the threaded holes. According to the motor welding strength test fixture, the permanent magnet stepping motorcan be fixed, the welding strength of the permanent magnet stepping motor can be conveniently tested, and meanwhile the fixture is simple in structure, long in service life and low in cost.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of motor testing, in particular to a jig for testing the welding strength of a motor and a method for testing the welding strength. Background technique [0002] The existing permanent magnet stepper motors on the market have a housing that includes an upper casing, a lower casing, and a fixing plate connected to the upper casing and the lower casing respectively. The middle parts of the upper casing and the lower casing are through holes. The upper casing or lower casing and the fixed plate are fixed by spot welding, the fixed plate seals the through hole, and the upper casing and the lower casing are fixed by electric welding riveting, because there is no test on the upper casing and the lower casing The support position cannot detect the welding strength between the upper casing or the lower casing and the fixed plate, nor can it detect the welding strength between the upper casi...
