Description

Technical Field

[0001] This invention relates to the field of force measuring device technology, and specifically to a force measuring device for a glove machine spring needle. Background Technology

[0002] As the name suggests, a glove knitting machine is used to knit gloves, and gloves are becoming increasingly widely used. Glove knitting machines can knit gloves with various patterns and styles by selecting the appropriate spring needles through a needle selection device. During the operation of the glove knitting machine, the spring needles may break or deform, causing misalignment of the knitted pattern. To ensure the accuracy of the knitted pattern, a force measuring fixture is needed to measure the force of each spring needle after it is installed on the glove knitting machine's needle plate. Currently, there is no dedicated equipment for measuring the force of glove knitting machine springs on the market, so a force measuring device needs to be designed based on the structural precision of the glove knitting machine's needle plate. Summary of the Invention

The force measuring mechanism is slidably mounted on the workpiece clamping mechanism via the force measuring translation mechanism. The force measuring mechanism includes a force measuring drive, a force measuring sensor, and a force measuring base. The force measuring base is mounted on the force measuring translation mechanism, the force measuring drive is mounted on the force measuring base, and the force measuring sensor is mounted on the force measuring drive and is positioned towards the workpiece clamping mechanism.

Detailed Implementation

[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] This force measuring device is used to measure the force of each spring needle 5 on the glove machine needle plate 4, thereby ensuring that the spring needle 5 has a relatively consistent rebound force within the same deformation range, thus ensuring the stability of the glove machine needle plate 4 during the knitting process. One side of the spring needle 5 is installed on the glove machine needle plate 4, and the other end is a free end. This force measuring device performs force measurement on the free end of the spring needle 5.

[0023] A force measuring device for spring needles of a glove machine includes a workpiece clamping mechanism 1, a force measuring mechanism 2, and a force measuring translation mechanism 3. The force measuring mechanism 2 is slidably mounted on the workpiece clamping mechanism 1 via the force measuring translation mechanism 3. The workpiece clamping mechanism 1 clamps and fixes the needle plate 4 of the glove machine. The force measuring mechanism 2 is moved to a position directly opposite each spring needle 5 by the force measuring translation mechanism 3, thereby facilitating the force measurement of each spring needle 5 and ensuring that each spring needle has a relatively consistent rebound force within the same deformation range.

[0024] The force measuring mechanism 2 includes a force measuring drive, a force measuring sensor 2-1, and a force measuring base 2-2. The force measuring base 2-2 is mounted on the force measuring translation mechanism 3, the force measuring drive is mounted on the force measuring base 2-2, and the force measuring sensor 2-1 is mounted on the force measuring drive and is positioned facing the workpiece clamping mechanism 1. The force measuring drive drives the force measuring sensor 2-1 to move up and down, thereby realizing the downward and upward testing of the spring needle 5.

[0025] The force-measuring drive unit includes a force-measuring motor 2-3, a force-measuring lead screw assembly 2-4, a slide rail 2-5, a slider 2-6, and a connecting piece 2-7. The force-measuring motor 2-3 and the slide rail 2-5 are respectively mounted on the force-measuring base 2-2. The slider 2-6 is slidably mounted on the slide rail 2-5. The connecting piece 2-7 is mounted on the slider 2-6. The force-measuring motor 2-3 is connected to the connecting piece 2-7 through the force-measuring lead screw assembly 2-4. The force sensor 2-1 is mounted on the connecting piece 2-7. The force sensor 2-1 moves up and down by moving the connecting piece 2-7 up and down through the force-measuring lead screw assembly 2-4.

[0026] A pressure limiting component 2-8 is installed on the force measuring base 2-2. The pressure limiting component 2-8 is adapted to the slider 2-6. The pressure limiting component 2-8 limits the pressure distance of the slider 2-6, ensuring that the pressure distance of the force measuring sensor 2-1 remains consistent in each pressure operation.

[0027] A force-bearing rod 2-9 is fixedly connected to the lower end face of the force sensor 2-1. The reaction force of the spring needle is transmitted to the force sensor 2-1 through the force-bearing rod 2-9. A crossbar 2-10 is fixedly connected to the end of the force-bearing rod 2-9. The end of the spring needle is hooked by the crossbar 2-10, thereby pulling up to measure the force.

[0028] When the force is pulled up, the crossbar 2-10 moves down through the gap between the spring pins 5 to a position below the lower end face of the spring pins 5. Then, the force measuring translation mechanism 3 translates the crossbar 2-10 so that it moves directly below the spring pins 5, thereby realizing the force measurement.

[0029] A force measuring display 2-11 is installed on the force measuring base 2-2. The force measuring sensor 2-1 is a tension / compression sensor. The data detected by the tension / compression sensor is transmitted to the force measuring display 2-11 or computer analysis software, so as to facilitate the display of the force measurement status of each spring pin and replace the spring pin that does not meet the requirements according to the data results.

[0030] The workpiece clamping mechanism 1 includes a base plate 1-3 and a workpiece clamping assembly 1-1 and a timing assembly 1-2 mounted on the base plate 1-3. The timing assembly 1-2 is installed between the workpiece clamping assembly 1-1 and the force measuring mechanism 2. The free end of the spring needle passes through the timing assembly 1-2, so that the spring needle is located below the force measuring mechanism. The timing assembly 1-2 limits the spring needle during the pull-up test to ensure that the pull-up deformation is consistent in each force measurement.

[0031] The workpiece clamping assembly 1-1 includes a first fixing plate 1-1-1, a second fixing plate 1-1-2, and a fixing clamp 1-1-3 arranged parallel to each other. The first fixing plate 1-1-1 and the second fixing plate 1-1-2 are respectively fixedly connected to the base plate 1-3. The first fixing plate 1-1-1 and the second fixing plate 1-1-2 are used to position and place the glove machine needle plate 4. The fixing clamp 1-1-3 is fixedly installed on the second fixing plate 1-1-2 and is used to fix the glove machine needle plate 4.

[0032] To facilitate the positioning and installation of the glove machine needle plate 4 on the first fixed plate 1-1-1 and the second fixed plate 1-1-2, a positioning groove 1-1-4 is formed on the first fixed plate 1-1-1, and a clamping groove 1-1-5 is formed on the second fixed plate 1-1-2. The positioning groove 1-1-4 is adapted to the clamping groove 1-1-5, and the fixing clamp 1-1-3 is installed above the clamping groove 1-1-5.

[0033] The timing component 1-2 has an arch bridge-shaped structure. The timing component 1-2 includes a connecting seat 1-2-1 and a conductive plate 1-2-2. The connecting seat 1-2-1 is fixedly installed on the base plate 1-3, and the conductive plate 1-2-2 is fixedly installed on the connecting seat 1-2-1. The conductive plate 1-2-2 is adapted to the highest point of the spring needle 5. That is, when the spring needle 5 springs up, the spring needle 5 contacts the conductive plate 1-2-2, which facilitates the device to record the time when the spring needle 5 springs up.

[0034] The conductive plate 1-2-2 is a conductive metal part. When the conductive plate 1-2-2 is connected to the wire, the spring pin 5 springs up and the conductive plate 1-2-2 forms a circuit, thereby generating a signal. The connector 1-2-1 is a nylon part, which ensures that the conductive plate 1-2-2 and the spring pin 5 are in an open circuit state.

[0035] The middle part of the conductive plate 1-2-2 is bent upward to form a bending surface 1-2-3, which enhances the transverse strength of the conductive plate 1-2-2 and improves the detection stability.

[0036] The force measuring translation mechanism 3 includes a translation component 3-1 and a guide component 3-2 arranged in parallel with each other. The force measuring mechanism 2 is connected to the translation component 3-1 and the guide component 3-2 to ensure the stable translation of the force measuring mechanism 2.

[0037] The translation component 3-1 includes a translation motor 3-1-1, a translation lead screw 3-1-2, and a translation slider 3-1-3. The translation motor 3-1-1 is connected to the translation lead screw 3-1-2, the translation slider 3-1-3 is mounted on the translation lead screw 3-1-2, and the force measuring mechanism 2 is connected to the translation slider 3-1-3.

[0038] The guide assembly 3-2 includes a guide rod 3-2-1 and a slider 3-2-2. The guide rod 3-2-1 is fixedly mounted on the base plate 1-3 via a bearing 3-2-3. The slider 3-2-2 is slidably mounted on the guide rod 3-2-1. The force measuring mechanism 2 is connected to the slider 3-2-2.

[0039] In this embodiment, a needle selector 4-1 is connected to the needle plate 4 of the glove machine. Multiple electromagnets are evenly connected inside the needle selector 4-1, and the spring needles are attracted by the electromagnets on the needle selector 4-1.

[0040] This force measuring device includes the following functions.

[0041] (a) Test the pressure required for the spring needle to press onto the electromagnet. Press down the spring needle onto the electromagnet by the force measuring drive component. Test the pressure of the pressing by the force measuring sensor 2-1 and test the elasticity property of the spring needle 5 itself.

[0042] (ii) Test the pulling force required for the spring needle to separate from the electromagnet. The spring needle is pulled up by the upward movement of the force measuring drive until it separates from the electromagnet. The maximum upward pulling force at the separation is tested by the force measuring sensor 2-1, and the maximum material suction of the needle selector 4-1 on the spring needle 5 is detected.

[0043] (III) Testing the time required for the needle selector 4-1 to be energized until the spring needle 5 separates from the needle selector 4-1 and the conductive plate 1-2-2 comes into contact. When the needle selector 4-1 is energized, the timer starts counting. When the needle selector 4-1 is energized, the electromagnet on the needle selector 4-1 is gradually demagnetized until the spring needle 5 springs up. When the spring needle 5 springs up, it comes into contact with the conductive plate 1-2-2, forming a current loop, thereby generating an electrical signal. The electrical signal is sent to the software timer, causing the counter to stop counting, thus recording the time required for the spring needle 5 to spring up. This is used to test the cooperation performance between the spring needle 5 and the needle selector 4-1, ensuring that when the needle selector 4-1 is energized and demagnetized, the time required for the spring needle 5 to spring up and come into contact with the conductive plate 1-2-2 is kept within a certain error range.

[0044] When performing the functional (iii) test, each spring pin 5 is tested individually. That is, after the previous spring pin 5 passes the above test steps, the spring pin 5 is pressed down onto the needle selector 4-1 before the spring time test of the next spring pin 5 is performed.
