Description

Technical Field

[0001] The utility model relates to the technical field of push rod detection, in particular to a device capable of measuring the extension and contraction amount and the transverse pulling force of the push rod. Background Art

[0002] The push-pull force gauge is a mechanical measuring instrument used for push and pull tests. It is suitable for push-pull load force testing in industries such as electronics and electrical appliances, light industry and textiles, building hardware, lighters and ignition devices, fire fighting equipment, pen making, lock making, fishing gear, power machinery, scientific research institutions, etc. For example, it is used to test the breaking force of hair in the cosmetics industry; it is used to measure the strength of packaging materials such as tapes and films in the packaging industry.

[0003] At present, most push-pull force gauges are handheld designs with small size, simple operation, and can be used in combination with various fixtures. When using a push-pull force gauge to measure the extension and retraction of the electric push rod, the push-pull force gauge must use manpower to push / pull to make a judgment. During the push / pull period, the force on the product is uneven, so the measured value is definitely inaccurate, which will result in a lot of time spent on measuring a product, and the accuracy is still not up to the requirements. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide a device that can improve measurement accuracy, is simple and convenient to operate, and has high efficiency and can measure the extension and retraction amount of the push rod and the lateral pulling force.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A device for measuring the extension and contraction of a push rod and the transverse pulling force, comprising a base plate,

[0007] A main bracket is fixedly mounted on the bottom plate, a camera seat is mounted on the main bracket via an optical slide, a camera is fixedly mounted on the camera seat, and a camera acquisition end of the camera is arranged downward;

[0008] A fixture for placing the electric push rod is fixedly installed on the bottom plate;

[0009] A main linear guide and a secondary linear guide are fixedly mounted on the bottom plate, a main slider is slidably mounted on the main linear guide, two secondary sliders are slidably mounted on the secondary linear guide, an active block is fixedly mounted on the main slider, a passive block is fixedly mounted on the secondary slider, a detent pin and a connecting seat are formed at both ends of the active block, the detent pin is located between the two passive blocks, a connecting pin is fixedly mounted on the connecting block, and a connecting hole is provided at the push rod end of the electric push rod to be plugged and matched with the connecting pin;

[0010] A sensor bracket is fixedly mounted on the bottom plate, a pressure sensor is fixedly mounted on the sensor bracket, and the passive block is connected to the detection end of the pressure sensor via a tension spring.

[0011] In this way, when testing the extension and retraction amount and lateral pulling force of the electric push rod, the electric push rod is placed in the fixture, and the connecting hole at the push rod end of the electric push rod cooperates with the connecting pin. When measuring the extension amount of the electric push rod, the electric push rod is energized and extends, and one of the passive blocks is pushed to move through the active block, and the tension spring connected to the passive block is pulled. When the push rod is extended to the maximum length, the camera takes a picture of the extension amount of the electric push rod and measures and judges the extension amount. If NG, the condition box on the computer screen will turn red, otherwise it will turn green. The tension spring connected to the passive block gives a pressure to the pressure sensor, and the pressure sensor displays the received force on the screen connected to it to judge whether the requirements are met. Similarly, when measuring the contraction amount of the electric push rod, after the electric push rod is energized, the push rod contracts and will push another passive block to move through the active block. The tension spring connected to the passive block is stretched. When the push rod is retracted, the camera takes a picture of the contraction amount of the electric push rod and measures and judges the contraction amount. If NG, the condition box on the computer screen will turn red, otherwise it will turn green. The tension spring connected to the passive block applies pressure to the pressure sensor, and the pressure sensor displays the force received on the screen connected to it to determine whether the requirements are met.

[0012] Wherein, a positioning pin for positioning the electric push rod is fixedly installed in the fixture.

[0013] Among them, LED brackets are fixedly installed on both sides of the main bracket, and a light source is fixedly installed on the LED bracket. The light source is in a ring shape and is arranged below the camera.

[0014] Wherein, a limiting rod is fixedly installed on the bottom plate corresponding to the passive block.

[0015] Wherein, a rib plate is fixedly installed between the main bracket and the base.

[0016] Wherein, a foot cup is fixed downward at the lower corner of the base.

[0017] In summary, this device for measuring the extension and contraction of the push rod and the transverse pull-out force has the advantages of improving measurement accuracy, simple and convenient operation, and high efficiency. This device has a simple structure and high precision. It can measure the corresponding push-pull force while measuring the extension and contraction. It only needs manual placement. This device eliminates the need for manual measurement of extension and pull-out force, greatly saving time and labor costs. The data accuracy measured by the camera is about ±0.005, which is more accurate than manual measurement, thereby better ensuring the quality of the product. BRIEF DESCRIPTION OF THE DRAWINGS
