Description

Technical Field

[0001] This utility model relates to a large circular knitting machine debugging device, and in particular to a large circular knitting machine pressure needle double-head debugging and measuring device. Background Technology

[0002] The following are the main shortcomings in the current field of large circular knitting machine pressure pin debugging: 1. Traditional measuring devices use a single-point fixed structure, which cannot achieve simultaneous dual-head detection, resulting in low debugging efficiency; 2. The existing equipment's test gauges are installed in fixed positions, making it difficult to adapt to the measurement needs of different models and locations; 3. The position of the traditional pressure needle is inspected manually by visual inspection, which cannot guarantee the efficiency and accuracy of the inspection.

[0003] This results in existing equipment having problems such as low debugging accuracy, narrow applicability, and complex operation.

[0004] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a double-headed adjustment and measurement device for the pressure needle of a large circular knitting machine, so as to make it more valuable for industrial use. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a double-headed adjustment and measuring device for the pressure needle of a large circular knitting machine.

[0006] This utility model discloses a double-headed adjustment and measuring device for a large circular knitting machine needle, including a mounting base, a support seat fixed to the upper end of the base by bolts, a movable moving block installed above the support seat, a vertical upright on the moving block, a liftable sliding block installed on the upright, and adjustable measuring gauges installed on both sides of the sliding block.

[0007] The dual-head adjustment and measuring device for the large circular knitting needle mainly consists of a mounting base, a support base, a moving block, a vertical rod, a sliding block, and a measuring gauge. The base is fixed to the support base with bolts. The support base is equipped with a horizontally movable moving block. A vertical rod is installed on the top of the moving block. An adjustable sliding block is installed on the vertical rod. A multi-directional adjustable measuring gauge is symmetrically installed on both sides of the sliding block. Through the coordinated operation of these components, the device achieves precise spatial adjustment of the dual measuring gauges.

[0008] Furthermore, the sliding block has screw holes at both ends, into which locking bolts are screwed. The ends of the locking bolts can contact the side wall of the upright to lock the position of the sliding block.

[0009] The device has screw holes at both ends of the sliding block. The locking bolt is screwed into the screw hole so that its end forms contact pressure with the side wall of the pole. The position locking function of the sliding block on the pole is achieved by the friction between the bolt and the pole.

[0010] Furthermore, a first mounting rod is fixed on both sides of the sliding block in a straight line. A first mounting block that can slide and rotate around the axis of the first mounting rod is mounted on the first mounting rod. A second mounting rod extends from one end of the first mounting block. A first adapter block that can slide and rotate around the axis of the second mounting rod is mounted on the second mounting rod. A rotatable third mounting rod is installed in the through groove at the end of the first adapter block. A second mounting block that can slide and rotate around the axis of the third mounting rod is mounted on the third mounting rod. A fourth mounting rod extends from one end of the second mounting block. A second adapter block that can slide and rotate around the axis of the fourth mounting rod is mounted on the fourth mounting rod. A test gauge is installed in the through groove at the end of the second adapter block.

[0011] The reference axis is formed by the first mounting rods fixed on both sides of the sliding block. The first mounting block can slide on the first mounting rod and rotate around it. The extended second mounting rod drives the first adapter block to achieve dual degree of freedom adjustment. The third mounting rod forms a rotating pair through the through groove of the first adapter block and connects to the second mounting block. The extended fourth mounting rod of the second mounting block cooperates with the second adapter block to form a third adjustment mechanism. Finally, the detection gauge in the through groove of the second adapter block completes the multi-level linkage positioning, realizing the all-round precise adjustment function of the spatial position of the detection gauge.

[0012] Furthermore, the test gauge is fixed to the adapter with bolts, and an adapter rod is fixed to the tail end of the adapter. The adapter rod extends into the through groove at the end of the second adapter block.

[0013] The test gauge is rigidly connected to the adapter seat by bolts. The adapter rod fixed at the tail end of the adapter seat is inserted into the through groove of the second adapter block to form a rotating pair. This structure connects the test gauge with a multi-stage adjustment mechanism in series. The fine adjustment function of the test gauge angle is realized by the rotational freedom of the adapter rod in the through groove.

[0014] Furthermore, the support base is hollow inside, and the positioning strip is inserted into the support base by interference fit. The surface of the positioning strip has multiple concave limiting screw holes, and the middle of the moving block has a through hole. A tightening bolt is screwed into the screw hole, and the lower end of the tightening bolt can be screwed into the limiting screw hole.

[0015] The hollow structure inside the support base provides installation space for the positioning strip. Through interference fit, the positioning strip and the support base are firmly connected. Multiple recessed limit screw holes on the surface of the positioning strip and the tightening bolt in the through hole of the moving block constitute an adjustable positioning mechanism. Screw in the tightening bolt so that its lower end is embedded in the limit screw hole, thereby realizing the position locking and front and back position adjustment functions of the moving block on the positioning strip.

[0016] Furthermore, the base contains a magnetic attachment part, which is attached to the large circular machine for adsorption.

[0017] The integrated magnetic attachment inside the base allows for quick installation with the large circular knitting machine via magnetic attraction. This design utilizes magnetic properties to ensure a stable connection between the base and the equipment, while also facilitating disassembly and repositioning.

[0018] Furthermore, the bottom of the base has an inwardly recessed positioning groove.

[0019] The positioning groove at the bottom of the base can be matched with the annular support ring on the outer circumference of the large circular knitting machine to achieve positioning and installation.

[0020] By employing the above-described solution, this invention possesses at least the following advantages: This dual-head adjustment and measuring device for large circular knitting machines enables omnidirectional adjustment of the spatial position of the testing gauges, breaking through the limitations of traditional single-point fixation. It allows two testing gauges to independently complete multi-directional synchronous testing, significantly improving adjustment efficiency. The combination of a magnetic base and positioning slot facilitates rapid adaptation to large circular knitting machines. Furthermore, through a multi-stage linkage mechanism and an adjustable positioning system, the testing device possesses precise position locking and angle fine-tuning capabilities, effectively solving problems such as low adjustment accuracy and complex operation of traditional equipment. This greatly expands the scope of application, lowers the technical threshold for operators, and provides an efficient and reliable measurement solution for pressure gauge adjustment.

[0021] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this invention are described in detail below with reference to the accompanying drawings.

[0024] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0025] See Figure 1 The device fixes the base 1 to the support 2 with bolts. A horizontally movable block 3 is installed on the support 2. A vertical pole 4 is installed on the top of the movable block 3. A liftable sliding block 5 is installed on the pole 4. Multi-directional adjustable gauges 6 are installed on both sides of the sliding block 5. This modular installation method enables the detection device to have dual-head synchronous detection capability. The combined adjustment function of the movable block 3 and the sliding block 5 can adapt to the measurement needs of different models. The multi-degree-of-freedom adjustment of the gauges 6 significantly improves the debugging accuracy. At the same time, the coordinated work of each component simplifies the operation process and achieves efficient and accurate needle adjustment.

[0026] The end of the test gauge 6 is a contact point that contacts the pressure needle. The displacement of the contact point drives the pointer inside the gauge to rotate. The pointer, in conjunction with the scale inside the gauge, allows the operator to read the distance of the contact point displacement, thereby obtaining the relative position of the pressure needle. This facilitates position reading of pressure needles in multiple different positions.

[0027] The pressure needles are arranged in two groups within the large circular knitting machine, with slight differences in position between each group. Therefore, using two inspection gauges 6 allows for simultaneous synchronous inspection of the pressure needles arranged in a spaced-out manner, improving inspection efficiency.

[0028] The test table 6 is a pointer-type indicator, which is a standard testing device, so it will not be described in detail here.

[0029] See Figure 1 The screw holes at both ends of the sliding block 5 are matched with the locking bolts 7. By screwing in the locking bolts 7, the end of the sliding block 5 is pressed against the side wall of the upright 4. The sliding block 5 is locked on the upright 4 by friction. This structure ensures that the sliding block 5 remains stable after the lifting and lowering adjustment through mechanical locking, avoiding position displacement caused by external force or vibration. At the same time, it simplifies the operation process and improves the reliability and ease of use of the debugging device.

[0030] See Figure 2The first mounting rod 8 fixed on both sides of the sliding block 5 serves as the reference axis. The first mounting block 9 can slide and rotate around the axis. The extended second mounting rod 10 drives the first adapter block 11 to achieve dual-degree-of-freedom adjustment. The third mounting rod 12 forms a rotating pair through the through groove of the first adapter block 11 and connects to the second mounting block 13. The fourth mounting rod 14 extended from the second mounting block 13 cooperates with the second adapter block 15 to form a third adjustment mechanism. Finally, the detection gauge 6 in the through groove of the second adapter block 15 completes the multi-level linkage positioning. This structure achieves all-round precise adjustment of the spatial position of the detection gauge 6 through multi-degree-of-freedom combination, which significantly improves the adaptability and operational flexibility of the debugging device.

[0031] See Figure 2 The gauge 6 is rigidly connected to the adapter 16 by bolts. The adapter rod 17 fixed at the tail end of the adapter 16 is inserted into the through groove of the second adapter block 15 to form a rotating pair. This structure combines the installation stability and adjustment flexibility of the gauge 6. The through groove design of the adapter rod 17 allows the gauge 6 to achieve precise angle fine adjustment under the action of the second adapter block 15. At the same time, the bolt fixing ensures that the gauge 6 maintains reliable positioning during dynamic measurement, improving the adaptability and measurement consistency of the debugging device.

[0032] See Figure 1 and Figure 3 The hollow structure of the support base 2 provides an interference fit installation space for the positioning strip 18. Multiple limiting screw holes 19 on the surface of the positioning strip 18 cooperate with the tightening bolts 20 screwed into the through holes of the moving block 3. The height positioning of the moving block 3 can be achieved by adjusting the tightening bolts 20 screwed into the limiting screw holes 19 at different depths. This design uses the mechanical interlock principle to ensure the stability of the support structure. At the same time, the multi-level limiting screw holes 19 provide flexible adjustment options to adapt to the installation requirements under different working conditions, combining ease of operation and positioning reliability.

[0033] The base 1 has a built-in magnetic suction unit that allows for quick installation by magnetic attraction with the large circular knitting machine. This design utilizes the magnetic attraction properties to allow the components to be stably connected without mechanical fixation, simplifying the disassembly and assembly process while avoiding damage to the structure caused by traditional bolts. The uniform attraction force provided by the magnetic suction unit ensures that the base 1 and the large circular knitting machine are in close contact, effectively reducing the risk of vibration and displacement, and improving the overall integrity and safety of the equipment during operation.

[0034] The magnetic attraction part can be a permanent magnet or an electromagnet. When an electromagnet is used, the battery that powers the electromagnet is built into the base 1. The battery is electrically connected to the charging interface and the switch to realize the opening and closing of the electromagnet, which makes it easy to install this device on a large circular knitting machine.

[0035] The positioning groove 21 at the bottom of the base 1 forms a precise guiding structure through its concave design, which enables quick alignment and installation when used with matching components. This design utilizes the principle of geometric constraints to ensure that the axis of the base 1 is aligned with that of the connecting components, reducing manual adjustment errors. At the same time, the concave structure of the positioning groove 21 can effectively disperse installation stress, avoid wear caused by rigid contact, and improve the assembly accuracy and long-term stability of the overall structure.

[0036] The positioning groove 21 has an arc-shaped structure, which can match the annular support ring of the large circular knitting machine.

[0037] The working principle of this utility model is as follows: First, the positioning groove 21 at the bottom of the base 1 is aligned with the arc-shaped structure of the support ring of the large circular machine, and the built-in magnetic attraction part is used to achieve quick adsorption and fixation. Then, the support base 2 is rigidly connected to the base 1 by bolts, and the positioning strip 18 is inserted into the hollow structure of the support base 2 with an interference fit. The height of the moving block 3 is locked by the tightening bolt 20 and the limiting screw hole 19. During the test, the operator first adjusts the moving block 3 to the horizontal position, and then fixes the lifting height of the sliding block 5 on the upright 4 by the locking bolt 7. Then, using the multi-degree-of-freedom adjustment mechanism of the first mounting rod 8, the second mounting rod 10, the third mounting rod 12 and the fourth mounting rod 14, the contact of the test gauge 6 is accurately aligned with the pressure needle. The displacement data is read by the pointer indicator. The simultaneous operation of the two test gauges 6 can efficiently complete the position detection of the two sets of pressure needles.

[0038] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
