The phenomenon that connecting rods which are not machined and are machined in a wrong mode flow into users is fundamentally overcome, the production efficiency is effectively improved, the cost is reduced, and the requirement of mass production is met.
The utility model discloses a main technical scheme: the device comprises a flat plate, a positioning core, a bracket, a sensor, a screw, a small head side positioning block, an alarm, a small head inclined plane detection block and a pin, and is structurally characterized in that the positioning core is arranged on the left part of the central line of the flat plate in an interference fit manner, a groove of the positioning core is vertical to the central line of the flat plate, the two sides of the positioning core are close to the edges of the flat plate, the bracket is respectively arranged through the screw, and the sensor is respectively arranged on the bracket through the screw; a small head inclined plane detection block is arranged on the right part of the flat plate along the central line through a screw and a pin, a small head side positioning block is arranged on the upper side of the flat plate through the screw and the pin, and an alarm is arranged beside the flat plate.
The utility model discloses an actual application proves: the device completely achieves the aim of development, overcomes the problem of unreliable manual visual inspection, and can accurately identify the problems of wrong and processing-missing of the connecting rod tile groove and processing-missing of the small-end inclined plane in the using process; the device is used for several months, and the phenomenon that the unqualified tile groove and the connecting rod with the small head bevel are flowed into a user is not generated. The utility model discloses a change less part, can also be used for the connecting rod inspection of multiple model, reduced manufacturing cost effectively, promoted user's satisfaction.

Detailed Description
Referring to fig. 4 and 5, the main technical solution of the present invention is explained, which comprises a flat plate 4, a positioning core 5 (see fig. 6), a bracket 6, a sensor 7, a screw 8, a small head side positioning block 9, an alarm 10, a small head inclined plane detection block 11 (see fig. 7), and a pin 12, and the structure thereof: a positioning core 5 is arranged on the left part of the flat plate 4 along the central line in an interference fit manner, the groove of the positioning core is vertical to the central line of the flat plate 4, two sides of the positioning core 5 are close to the edges of the flat plate 4, a bracket 6 is respectively arranged on each side of the positioning core through a screw 8, and a sensor 7 is respectively arranged on each bracket through a screw; a small head inclined plane detection block 11 is arranged on the right part of the flat plate 4 along the central line through a screw 8 and a pin 12, a small head side positioning block 9 is arranged on the upper side of the flat plate through a screw and a pin, and an alarm 10 is arranged beside the flat plate.
Referring to fig. 4, the sensor 7 adopts a laser displacement sensor, and when the displacement of the detected object and the set displacement change by more than 1mm, the sensor can identify and send a signal to an alarm, and the sensor is a common sensor and purchased from the market; the alarm 10 is a common alarm purchased from the market; the upper part of the positioning core 5 (shown in figure 6) is provided with a groove with the width of 5-6mm along the diameter direction, and the positioning core is used for directly aligning the sensor 7 with the positions of two tile grooves in the big hole of the connecting rod; the small end inclined plane detection block 11 (see fig. 7) is provided with a through groove with the same shape as the two inclined planes of the small end of the connecting rod, and is mainly used for detecting whether the two inclined planes of the small end of the connecting rod are processed in a missing mode.
