Description

Technical Field

[0001] The utility model relates to a motor iron core chute inspection fixture. Background Art

[0002] The motor core skew inspection fixture is used to detect the twist angle of the core from top to bottom, and to detect whether the skew is neat and whether each piece is rotated evenly by the same angle. In traditional inspection methods, the measurement methods usually include: line drawing measurement method, comparison measurement method, tooling inspection method, etc.

[0003] Line drawing measurement method: Draw a line and use a vernier caliper to measure the rotation distance. When measuring, the line drawing ruler moves horizontally to draw a line segment of a certain depth. Then use the vernier caliper to measure the distance the groove has rotated. Due to problems such as the depth of the scale line, it is easy to have a large error in the product. At the same time, the efficiency is low. It usually takes several minutes to test a sample, which is far from the expected production cycle. And the requirements for measurement personnel are high, and professional training is required;

[0004] Comparative measurement method: The comparative measurement method is to compare the standard angle with the actual angle to determine whether the product is qualified. Since the standard angle is converted according to customer requirements, the sample is qualified as long as it is within the standard angle. Usually, a simulated block or transparent film of the bevel angle is made, and the product is quickly measured by visual comparison. The comparative measurement method is a simple tool used by industrial manufacturers to control various dimensions of products. It is suitable for mass-produced products, such as automotive parts, to replace professional measuring tools such as vernier calipers, depth gauges, etc. For specific product features, it can quickly and effectively detect whether it is qualified.

[0005] However, the traditional line drawing measurement method and comparison measurement method usually take several minutes. And the requirements for the inspection personnel are high. Non-professionals cannot complete accurate inspection, which is inefficient and seriously affects the continuity of production. In addition, traditional inspection has certain inspection defects, such as the thickness of the line drawing, no reading of the comparison method, etc.; it is impossible to comprehensively and accurately measure the true state of the product.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1 The schematic diagram of the structure of the present application shows a motor core chute inspection fixture, which includes a product positioning seat 1 and a detection plate arranged on one side of the product positioning seat; the detection plate is a rectangular detection plate 2, and a rectangular slot 4 is arranged on the top edge of the rectangular detection plate to form an "L"-shaped notch 5 and a scale 6; the scale is provided with scales. The product positioning seat is used to place products, and the notch and scale on the detection plate can be used to intuitively detect the motor chute and quickly read data; because the detection plate and the product positioning seat are detachably connected, the two can have more combinations, which is convenient for detecting products of different models.

[0025] The horizontal side of the notch is provided with a first chamfer 7, and the vertical side of the notch is provided with a second chamfer 8. The first and second chamfers are provided for easy observation during detection.

[0026] A product placement groove 9 is provided in the center of the top surface of the product positioning seat, and the cross section of the product placement groove is in the shape of an inverted isosceles trapezoid. The isosceles trapezoidal structure is more stable.

[0027] The product positioning seat has a groove 10 on the side, and the detection plate has a convex strip 11 on the side that cooperates with the groove. When assembling the inspection tool, the convex strip of the detection plate is aligned with the groove and inserted into the bottom, and then it is determined as a convex block limit to reach the specified position.

[0028] A positioning protrusion 12 is provided at one end of the groove to limit the sliding position of the protrusion, so that it will not move after moving to the specified position.

[0029] It also includes a clamping adjustment component; the clamping adjustment component includes an inverted U-shaped bracket 13, and the bottom of the bracket legs on both sides of the bracket are provided with clamping blocks 14; the clamping blocks are located inside the bracket legs 15, and pass through the corresponding bracket legs through the adjustment rod 16 and extend out of the bracket legs. The adjustment rod is screwed in and out to control the clamping and loosening of the clamping block on the product to be tested; after the product to be tested is clamped, the U-shaped bracket is manually driven to rotate so that the product to be tested is rotated to a suitable angle.

[0030] One end of the adjusting rod extending out of the bracket leg is connected to the motor. The motor controls the screwing in and out of the adjusting rod, and indirectly controls the position of the clamping block.

[0031] Here is how to use it. Just place the product on the product positioning seat, align the left end of the product bevel with the horizontal section of the detection plate, and align the right end of the product bevel with the scale of the detection plate, and you can read the actual angle.
