Description

Technical Field

[0001] The utility model belongs to the field of measurement, and more specifically relates to a universal nail riveting depth measuring device. Background Art

[0002] A universal nail is a universal fastener, also called a universal pin or connecting pin, which usually consists of two parts: a pin with threads and a nut with corresponding threads.

[0003] During installation, the nut needs to be tightened on the threaded end of the pin. The two parts are connected together through the pin and the nut, and then the nut is tightened to ensure a firm and stable connection. In order to facilitate the measurement of the riveting depth, small round holes are symmetrically opened on the side wall of the nut.

[0004] In the prior art, after the universal nail is riveted, the depth of the riveted position needs to be measured to see whether it is qualified. During the inspection, the universal nail riveting depth is usually measured manually using a vernier caliper. This self-inspection method is very inefficient. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a universal nail riveting depth measuring device, which does not require manual measurement and improves the detection efficiency.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] The utility model also comprises a depth measuring component which is electrically connected with the alarm and measures the riveting depth of the universal nail.

[0009] The advantages of this solution are at least as follows: the universal nail is placed in the fixture, the drive assembly is started, the drive assembly drives the fixture to move on the guide rail, and the fixture is moved next to the depth measuring assembly. At this time, the depth measuring assembly is started and the depth of the riveting position of the universal nail is measured. If it meets the requirements, the alarm will sound, otherwise, if it does not meet the requirements, the alarm will sound, thereby judging whether the riveting depth of the universal nail meets the standard, without the need for manual measurement, thereby improving the detection efficiency.

[0010] The utility model is further configured as follows: the driving assembly comprises a cylinder mounted on the side wall of the base, an L-shaped plate is fixedly mounted on the output end of the cylinder, and the L-shaped plate is fixedly connected to the clamp.

[0011] The advantages of this solution are at least that the cylinder is faster and more convenient to operate than the motor screw slider assembly, and it is also easier to repair and replace parts later.

[0012] The utility model is further configured as follows: the depth measuring component includes a pneumatic clamp, two mounting heads are installed at the output end of the pneumatic clamp, a vernier caliper is installed on the mounting head, two jaws of the vernier caliper are fixed on the mounting head, one of the jaws is provided with a fixing needle, the fixing needle head is semicircular, and a measuring needle is provided on the other jaw, and the fixing needle and the measuring needle are arranged toward the universal pin.

[0013] The advantages of this solution are at least that the two jaws of the vernier caliper are fixed on the mounting head at the output end of the pneumatic clamp, and the vernier caliper can be operated simply by starting the pneumatic clamp, making the operation more automated. The setting of the fixed needle and the measuring needle facilitates insertion into the small circular hole on the side wall of the nut, making the measurement more accurate.

[0014] The utility model is further configured as follows: a guide rail 2 is installed on the base, a sliding seat is slidably installed on the guide rail 2, the pneumatic clamp is fixedly installed on the sliding seat, fixed blocks are installed at both ends of the guide rail 2, and a spring is installed between the side walls of the two fixed blocks and the side walls of the sliding seat.

[0015] The advantage of this solution is at least that when the fixing needle needs to be inserted into the small circular hole on the side wall of the nut, under the action of the spring, the pneumatic clamp and the sliding seat can move on the guide rail 2, so that the fixing needle can adaptively enter the small circular hole on the side wall of the nut.

[0016] The utility model is further configured as follows: the depth measuring assembly, the second guide rail, the sliding seat, the fixing block and the spring are all configured as two groups and are symmetrically mounted on the base.

[0017] The advantages of this solution are at least that the depth measuring assembly, the second guide rail, the sliding seat, the fixing block and the spring are arranged in two groups, which facilitates the measurement of the riveting depth on both sides of the universal nail and improves the applicability of the measuring device.

[0018] The utility model is further configured as follows: a proximity switch sensor is installed on the side wall of the second guide rail, and the two adjacent proximity switch sensors are arranged facing each other.

[0019] The advantage of this solution is at least that the proximity switch sensor is provided to position the cylinder when it moves, so that the fixture moves to the position measured by the depth measurement component.

[0020] In summary, the utility model has at least the following advantages:

[0021] 1. By setting a driving component, a depth measuring component and an alarm electrically connected to the depth measuring component, the universal nail is placed in the fixture, the driving component is started, and the driving component drives the fixture to move on the guide rail 1, and the fixture is moved to the side of the depth measuring component. At this time, the depth measuring component is started and the depth of the universal nail riveting position is measured. If it meets the requirements, the alarm will sound, otherwise, if it does not meet the requirements, the alarm will sound. It can also be realized to judge whether the universal nail riveting depth meets the standard, without manual measurement, thereby improving the detection efficiency;

[0022] 2. By arranging the guide rail 2, the sliding seat, the fixed block and the spring between the side wall of the fixed block and the side wall of the sliding seat on the base, when the fixed needle needs to be inserted into the small round hole on the side wall of the nut, under the action of the spring, the pneumatic clamp and the sliding seat can move on the guide rail 2, so that the fixed needle can adaptively enter the small round hole on the side wall of the nut;

[0023] 3. By setting the depth measuring assembly, the second guide rail, the sliding seat, the fixed block and the spring into two groups, it is convenient to measure the riveting depth on both sides of the universal nail, thereby improving the applicability of the measuring device.
