For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] like Figures 1 to 5 As shown, a size detection device for automobile swing arm production includes a gauge table 1, one side of the gauge table 1 is fixedly connected with a placement plate 2, one side of the placement plate 2 is fixedly connected with two positioning columns 3, one side of the placement plate 2 is fixedly connected with a plurality of detection blocks 4, one side of the plurality of detection blocks 4 is fixedly connected with a magnetic block 5, one side of the plurality of detection blocks 4 is slidably connected with a measuring column 6, the measuring column 6 is made of iron material, one side of the plurality of measuring columns 6 is fixedly connected with a scale line 7, the zero scale line of the scale line 7 is in contact with one side of the detection block 4 and a workpiece 8, one side of the placement plate 2 is plugged with the workpiece 8, one side of the gauge table 1 is fixedly connected with three clamps 9, the pressure arm of the clamp 9 can rotate, which is a mature product of the prior art and will not be elaborated in detail in the utility model.

[0028] A first groove is provided on one side of the placement plate 2, and the inner surface of the first groove is matched with the outer surface of the workpiece 8. The workpiece 8 is inserted into the first groove. When testing, the workpiece 8 is placed in the groove of the placement plate 2, and passes through the positioning column 3 to limit the workpiece 8. Then, by moving the tail end of the pressure arm 9 of the clamp 9, the front end of the clamp 9 presses the workpiece 8 tightly and fixes it on the placement plate 2.

[0029] A first through hole is formed on one side of the workpiece 8 , the inner surface of the first through hole matches the outer surface of the positioning column 3 , and the positioning column 3 is inserted into the first through hole.

[0030] A plurality of detection blocks 4 are evenly distributed outside the first groove at the top of the placement plate 2. Before taking readings, check whether the zero scale line of the scale line 7 on the measuring column 6 is in contact with the end of the detection block 4 away from the workpiece 8.

[0031] The top height of the measuring column 6 is smaller than the top height of the workpiece 8 .

[0032] A second groove is formed on one side of the detection block 4 , the inner surface of the second groove is matched with the outer surface of the magnetic block 5 , and the magnetic block 5 is fixedly connected to the inside of the second groove.

[0033] A second through hole is provided on one side of the detection block 4, and the inner surface of the second through hole is matched with the outer surface of the measuring column 6.

[0034] The surface of the top of the magnetic block 5 is matched with the outer surface of one side of the measuring column 6. One side of the measuring column 6 is slidably connected to the top of the magnetic block 5.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] The workpiece 8 is limited and fixed by the cooperation of the positioning column 3, the groove on the placement plate 2 and the clamping claw 9 to avoid large measurement errors caused by work movement. The sliding distance of the measuring column 6 in the detection block 4 is read out by the contact between the measuring column 6 and the workpiece 8 and the scale line 7 to detect the size of the workpiece 8. The magnetic attraction of the magnetic block 5 inside the detection block 4 to the measuring column 6 can avoid the movement of the measuring column 6 during reading, which can make the measurement data inaccurate.
