Description

Technical Field

[0001] This utility model relates to the field of insulating paper indentation preparation technology, and in particular to a mechanism for preparing motor insulating paper indentation. Background Technology

[0002] In the field of motor insulation paper indentation preparation technology, traditional preparation mechanisms usually rely on molds to indent the insulation paper. The core structure of existing devices is that the two ends of the mold are connected to the moving parts or base of the preparation mechanism through fixed grooves, and the precise shape of the mold is used to apply pressure to the insulation paper to form specific marks. However, in long-term practice, such devices have revealed certain defects.

[0003] In pursuit of mold installation stability, most devices set the depth of the fixing groove to be much greater than the necessary embedding size at the mold end. This results in the need to overcome significant friction during mold disassembly. Furthermore, due to limited operating space, workers must rely on auxiliary tools or repeatedly adjust the force application angle, significantly reducing operational efficiency. Traditional designs do not consider a quick release function, and the disassembly process relies entirely on manual pulling. When the fixing groove depth exceeds 15mm (a common industry threshold), the force-bearing area at the mold end increases, further exacerbating disassembly resistance. This is especially true in production scenarios where molds are frequently changed, multiplying the labor intensity.

[0004] Therefore, there is an urgent need to provide a mechanism for preparing embossing for motor insulation paper to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a mechanism for preparing motor insulation paper indentation.

[0006] To solve the above-mentioned technical problems, the present invention provides a technical solution as follows: a mechanism for preparing indentations on motor insulation paper is provided, comprising a device body, two fixing grooves on the top of the device body, a fixing shaft placed in the two fixing grooves, a mold for preparing indentations on insulation paper fixedly connected to the outside of the fixing shaft, fixing rings for fixing the mold rotatably connected to both ends of the fixing shaft, an arc-shaped plate slidably connected in contact with the fixing rings in the two fixing grooves, and a driving mechanism rotatably connected to the bottom of the arc-shaped plate;

[0007] Both of the arc-shaped plates have a circular arc plate rotatably connected to their rear ends. A rotating mechanism connects the circular arc plate to the arc-shaped plates. A reset mechanism is connected to the rear end of the circular arc plate. A limit mechanism is fixedly connected to the bottom of both arc-shaped plates.

[0008] The present invention is further configured such that: the driving mechanism includes two electric push rods fixedly connected to the top of the device body; the output ends of the two electric push rods are fixedly connected to plates two; the other ends of the two plates two are rotatably connected to rods two; the other ends of the two rods two are rotatably connected to rods three; the other ends of the two rods three are respectively rotatably connected to the bottom of the two arc-shaped plates; and the tops of the two blocks two are fixedly connected to the top of the device body, with the tops of the two blocks two respectively contacting the other ends of the two rods two.

[0009] Through the above technical solution, the function of the drive mechanism is to drive the mold to lift upward. When the mold is to be lifted, the bolt is first removed, and then the handle is deflected, causing the arc plate to deflect and move away from the fixed ring. At this time, the torsion spring two is twisted, so that the torsion spring two is subjected to force. Then, the electric push rod is started by program control. This part involves software control and is existing technology. The electric push rod is started, causing the plate two to move downward, causing the rod two to deflect and move towards the mold, causing the rod two to deflect and move upward, causing the arc plate to move upward, causing the fixed ring to move upward, causing the fixed shaft to move upward, and causing the mold to move upward. This makes it convenient for the staff to take out the mold from the fixed groove without the need for auxiliary tools or repeated adjustment of the force angle, reducing disassembly resistance and reducing labor intensity. The function of the block two is to hold the rod two and rod three, causing them to deflect and move. The function of the fixed ring is to position the fixed shaft without affecting the rotation of the fixed shaft, and thus not affecting the rotation of the mold and the preparation of the indentation. The function of the fixed groove is to place and position the mold, and the function of the arc plate is to fit the fixed ring and position it.

[0010] The present invention is further configured such that: the rotating mechanism includes two first brackets respectively fixedly connected to the rear ends of the two arc-shaped plates; a second shaft is fixedly connected inside each of the two first brackets; a sleeve is rotatably connected to the outside of each of the two second shafts; a third plate is fixedly connected to the outside of each of the two sleeves; a stop block abutting against the third plate is fixedly connected inside each of the two fixed grooves; a second bracket is rotatably connected to the outside of each of the two sleeves; and the two second brackets are respectively fixedly connected to the two arc-shaped plates.

[0011] Through the above technical solution, the function of the rotating mechanism is to allow the arc plate to automatically cover the fixed ring. When the mold is to be lowered, the arc plate is located inside the fixed groove, and the plane of the arc plate is perpendicular to the ground, so it will not block the fixed ring. Plate three is parallel to the ground. The mold and the fixed rings on both sides of the fixed shaft are aligned with the arc plate and placed in. The fixed rings will fit against the arc plate. Then, the electric push rod is activated, which moves plate two downward, moves rod two outward, moves rod three downward, moves the arc plate downward, moves the fixed ring downward, moves the fixed shaft downward, and moves the mold downward. As the arc plate moves downward... During the movement, the first support moves downward, the second shaft moves downward, and the third plate moves downward. As the third plate moves, it comes into contact with and abuts against the stop block. The stop block holds the third plate against the stop block, causing it to deflect. When the third plate deflects, it twists the first torsion spring. The first torsion spring is under force, and the third plate deflects, causing the sleeve to deflect. At the same time, the second torsion spring causes the arc plate to deflect until the arc plate covers the top of the fixed ring. At this time, the arc plate and the arc plate are in contact with the fixed ring and position the fixed ring. Then, the bolt is rotated to press the arc plate against the fixed ring, thus fixing and reinforcing the mold. This is convenient, quick, simple, and practical, and does not require workers to manually cover the fixed ring.

[0012] The present invention is further configured such that: the reset mechanism includes two torsion springs 1 respectively sleeved on the outside of the two shafts 2, the two ends of the torsion springs 1 being fixedly connected to the plate 3 and the first bracket respectively, and torsion springs 2 are sleeved on the outside of the two sleeves respectively, the two ends of the torsion springs 2 being fixedly connected to the plate 3 and the second bracket respectively.

[0013] Through the above technical solution, the function of the reset mechanism is to enable the third plate and the arc plate to automatically reset. When the mold is not placed, the first torsion spring keeps the third plate in a position parallel to the ground, and the second torsion spring keeps the arc plate in a position. When the mold is placed and moves downward, the third plate contacts the stop block and is held in place by the stop block. At this time, the first torsion spring is under force, and the third plate deflects the arc plate through the second torsion spring. When the mold is to be disassembled, the deflection handle deflects the arc plate. At this time, the second torsion spring is under force until the third plate moves upward and disengages from the stop block. Under the action of the first torsion spring, the third plate automatically resets. After the third plate resets, the second torsion spring drives the arc plate to reset again. This method is convenient, quick, simple and practical.

[0014] The present invention is further configured such that: the limiting mechanism includes two third brackets respectively fixedly connected in two fixed slots, and each of the two third brackets is slidably connected with a limiting shaft respectively fixedly connected to the bottom of the two arc-shaped plates.

[0015] The above technical solution enables the limiting mechanism to limit the arc-shaped plate by guiding it through the limiting shaft, which is convenient, quick, simple and practical.

[0016] The present invention is further configured such that: a T-shaped block is fixedly connected to the front end of each of the two arc-shaped plates; a groove corresponding to the T-shaped block is opened in each of the two fixing grooves; a handle is fixedly connected to the outward end of each of the two arc-shaped plates; a bolt is rotatably connected to the top of each of the two fixing grooves; and the bottom of each bolt abuts against the top of the two arc-shaped plates.

[0017] Through the above technical solution, the T-block is used to further limit and guide the arc plate, and strengthen the limiting effect. The handle is used to facilitate the deflection of the arc plate. The bolt is used to provide long-term positioning of the arc plate, and then to position the fixing ring, fixing shaft and mold.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. This utility model achieves labor-saving mold disassembly through a drive mechanism. The design of the arc plate linked to the electric push rod and connecting rod assembly allows the disassembly process to be completed without the aid of auxiliary tools. The rotation mechanism achieves precise positioning and rapid locking of the mold during installation through the three-way deflection of the stop trigger plate, which greatly improves the assembly efficiency. The reset mechanism uses a double torsion spring structure to ensure rapid switching of equipment status.

[0020] 2. This utility model enhances the stability of the arc plate movement through the linear guidance of the limiting shaft and the T-block; the coordinated design of the handle and bolt facilitates the manual deflection operation of the arc plate and provides long-term positioning of the fixing ring, ensuring the reliability of mold indentation preparation; the coordinated action of each mechanism enables the mold replacement process to be fully automated and labor-saving, effectively reducing labor intensity and improving production efficiency.

[0029] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0030] Please see Figures 1-7The motor insulation paper embossing preparation mechanism of this embodiment includes a device body 1. Two fixing grooves 2 are formed on the top of the device body 1. A fixing shaft 3 is placed in each of the two fixing grooves 2. A mold 4 for preparing insulation paper embossing is fixedly connected to the outside of the fixing shaft 3. Fixing rings 5 ​​for fixing the mold 4 are rotatably connected to both ends of the fixing shaft 3. Arc-shaped plates 6 that contact the fixing rings 5 ​​are slidably connected to the two fixing grooves 2. A driving mechanism 7 is rotatably connected to the bottom of the arc-shaped plates 6. The driving mechanism 7 includes two electric push rods 70 fixedly connected to the top of the device body 1. 1. The output ends of the two electric push rods 701 are fixedly connected to plates 702. The other ends of the two plates 702 are rotatably connected to rods 703. The other ends of the two rods 703 are rotatably connected to rods 704. The other ends of the two rods 704 are rotatably connected to the bottom of the two arc-shaped plates 6 respectively. The top of the main body 1 is fixedly connected to two blocks 705. The tops of the two blocks 705 are in contact with the other ends of the two rods 703 respectively. The function of the drive mechanism 7 is to drive the mold 4 to lift upward. When you want to lift the mold 4, first remove the screw. Bolt 1105, then deflect handle 1104, causing the arc plate 8 to deflect and move away from the fixing ring 5. At this time, the torsion spring 1002 is twisted, causing the torsion spring 1002 to be stressed. Then, the electric push rod 701 is started by program control. This part involves software control and is existing technology. The electric push rod 701 is started, causing the plate 702 to move downward, causing the rod 703 to deflect and move towards the mold 4, causing the rod 703 to deflect and move upward, causing the arc plate 6 to move upward, causing the fixing ring 5 to move upward, and causing the fixing shaft 3 to move upward. The mold 4 is moved upward, making it easier for workers to remove the mold 4 from the fixed groove 2 without the need for auxiliary tools or repeated adjustment of the force angle, reducing disassembly resistance and labor intensity. The function of block 2 705 is to hold rod 2 703 and rod 3 704, causing them to deflect and move. The function of fixed ring 5 is to position fixed shaft 3 without affecting the rotation of fixed shaft 3, thus not affecting the rotation of mold 4 and the preparation of indentation. The function of fixed groove 2 is to place and position mold 4. The function of arc plate 6 is to fit fixed ring 5 and position it.

[0031] like Figures 3-6As shown, the rear ends of the two arc-shaped plates 6 are rotatably connected to arc-shaped plates 8. A rotating mechanism 9 connects the arc-shaped plates 8 and the arc-shaped plates 6. The rotating mechanism 9 includes two first brackets 901 respectively fixedly connected to the rear ends of the two arc-shaped plates 6. A shaft 902 is fixedly connected inside each of the two first brackets 901. A sleeve 903 is rotatably connected to the outside of each of the two shafts 902. A plate 904 is fixedly connected to the outside of each of the two sleeves 903. A stop block 905 that abuts against the plate 904 is fixedly connected inside each of the two fixing grooves 2. Each of the two components is rotatably connected to a second bracket 906, which is fixedly connected to two arc plates 8 respectively. The function of the rotating mechanism 9 is to allow the arc plates 8 to automatically cover the fixed rings 5. When the mold 4 is to be lowered, the arc plate 6 is located inside the upper part of the fixed groove 2, and the plane of the arc plate 8 is perpendicular to the ground and will not block the fixed rings 5. The plate 3 904 is parallel to the ground. The mold 4 and the fixed rings 5 ​​on both sides of the fixed shaft 3 are aligned with the arc plate 6 and placed in. The fixed rings 5 ​​will fit against the arc plate 6. Then the electric push rod 7 is activated. 01. This causes plate 702 to move downwards, rod 703 to deflect outwards, rod 704 to deflect downwards, arc plate 6 to move downwards, fixed ring 5 to move downwards, fixed shaft 3 to move downwards, and mold 4 to move downwards. During the downward movement of arc plate 6, it causes first bracket 901 to move downwards, shaft 902 to move downwards, and plate 904 to move downwards. During this movement, plate 904 will contact and abut against stop block 905, which will hold plate 904 in place. When deflection occurs, when plate 3 (904) deflects, it triggers the torsion spring 1 (1001). The torsion spring 1 (1001) is stressed, causing plate 3 (904) to deflect, which in turn causes sleeve 903 to deflect. At the same time, the torsion spring 2 (1002) causes the arc plate 8 to deflect until the arc plate 8 covers the fixed ring 5. At this point, the arc plate 6 and the arc plate 8 simultaneously come into contact with the fixed ring 5 and position the fixed ring 5. Then, the bolt 1105 is rotated to press the arc plate 8 against the fixed ring 5, thus fixing and reinforcing the mold 4. This method is convenient, quick, simple, and practical, eliminating the need for workers to manually cover the fixed ring 5.

[0032] like Figures 5-6As shown, a reset mechanism 10 is connected to the rear end of the arc plate 8. The reset mechanism 10 includes two torsion springs 1001 respectively sleeved on the outside of the two shafts 902. The two ends of the torsion springs 1001 are fixedly connected to the plate 904 and the first bracket 901 respectively. Two torsion springs 1002 are sleeved on the outside of the two sleeves 903 respectively. The two ends of the torsion springs 1002 are fixedly connected to the plate 904 and the second bracket 906 respectively. The function of the reset mechanism 10 is to enable the plate 904 and the arc plate 8 to automatically reset. When the mold 4 is not placed, the torsion springs 1001 keep the plate 904 in a position parallel to the ground, and the torsion springs 1002 maintain the arc. With plate 8 in the same position, when mold 4 is placed in and moves downward, plate 3 904 contacts stop 905 and is held in place by stop 905. At this time, torsion spring 1001 is under force, and plate 3 904 drives arc plate 8 to deflect through torsion spring 2 1002. When mold 4 is to be disassembled, deflection handle 1104 drives arc plate 8 to deflect. At this time, torsion spring 2 1002 is under force until plate 3 904 moves upward and disengages from stop 905. Under the action of torsion spring 1001, plate 3 904 automatically resets. After plate 3 904 resets, arc plate 8 is reset again through torsion spring 2 1002. This process is convenient, quick, simple and practical.

[0033] like Figures 1-7 As shown, the bottom of each of the two arc-shaped plates 6 is fixedly connected to a limiting mechanism 11. The limiting mechanism 11 includes two third brackets 1101 that are respectively fixedly connected in two fixed grooves 2. Each of the two third brackets 1101 has a limiting shaft 1102 that is respectively fixedly connected to the bottom of the two arc-shaped plates 6. The function of the limiting mechanism 11 is to limit the arc-shaped plates 6 and guide the arc-shaped plates 6 through the limiting shaft 1102. It is convenient, quick, simple and practical.

[0034] like Figure 7 As shown, T-blocks 1103 are fixedly connected to the front ends of the two arc plates 6. Slots corresponding to the T-blocks 1103 are opened in the two fixing slots 2. Handles 1104 are fixedly connected to the outward ends of the two arc plates 8. Bolts 1105 are rotatably connected to the top of the two fixing slots 2. The bottoms of the two bolts 1105 abut against the tops of the two arc plates 8. The function of the T-blocks 1103 is to further limit and guide the arc plates 6 and strengthen the limiting effect. The function of the handles 1104 is to facilitate the deflection of the arc plates 8. The function of the bolts 1105 is to provide long-term positioning for the arc plates 8, thereby positioning the fixing ring 5, the fixing shaft 3, and the mold 4.

[0035] In use, this utility model utilizes an electric push rod 701 to drive rods 703 and 704 to link with the arc plate 6, which, in conjunction with the deflectable arc plate 8, enables efficient assembly and disassembly of the mold 4. During disassembly, bolts 1105 are removed and the handle 1104 on the arc plate 8 is deflected. The electric push rod 701 is then activated, causing plate 702 to move downwards. Rods 703 and 704 then push the arc plate 6 upwards, lifting the mold 4. Block 705 abuts against rods 703 and 704 to ensure stable lifting. During assembly, the mold 4 is aligned with the fixing rings 5 ​​on both sides of the fixing shaft 3 and placed on the arc plate 6. After insertion, the electric push rod 701 is activated, and the second plate 702 moves down, causing the arc plate 6 to move down. When the third plate 904 contacts the stop block 905, it deflects, thereby driving the sleeve 903, the second torsion spring 1002, and the arc plate 8 to automatically cover the fixing ring 5. The bolt 1105 is tightened to complete the locking. The first torsion spring 1001 causes the third plate 904 to automatically reset after disassembly, causing the arc plate 8 to rebound through the second torsion spring 1002. The limit shaft 1102 and the T-block 1103 restrict the linear movement of the arc plate 6 throughout the entire process, ensuring precise and stable operation and realizing labor-saving and automated mold 4 replacement.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
