Description

Technical Field

[0001] This utility model relates to the field of motor stator and rotor processing technology, specifically a fixture for processing motor stator and rotor laminations. Background Technology

[0002] The stator and rotor are the core components of an electric motor. The stator is the stationary part, and the rotor is the rotating part. They convert electrical energy into mechanical energy through electromagnetic induction and are widely used in various types of electric motors and generators. Because stators and rotors are typically plate-like structures and need to meet high-precision dimensional requirements and mass production needs, progressive dies are commonly used in the industry for processing. A progressive die is a multi-station continuous stamping die that can complete multiple processes such as blanking, bending, and forming in a single stamping operation.

[0003] During the production of stator and rotor laminations, the progressive die needs to be stably fixed on the worktable of the stamping equipment to ensure stamping accuracy and operational safety. Currently, the mainstream fixing method is a combination of "T-slots + T-bolts": T-slots are pre-set on the surface of the worktable along the length or width direction, and corresponding fixing slots are opened on the bottom of the die. During installation, the head of the T-bolt is embedded into the T-slot of the worktable, and after the bolt passes through the fixing slot of the die, the die is tightened with a nut to achieve a rigid connection between the die and the worktable.

[0004] Due to factors such as machining errors between different batches of progressive dies, manufacturing tolerances of the T-slots on the worktable, and production and design errors from different manufacturers, there is a certain probability that the fixed slot reserved in the die will be misaligned with the T-slot on the worktable. In this case, the T-bolt cannot pass through both the T-slot and the fixed slot at the same time, which means that the die cannot be directly tightened and fixed by the bolt. It is necessary to re-machine the die, or not to use bolts to tighten this hole. The lack of bolts has a significant impact on the connection strength of the die, which increases the load on other bolts and makes them more prone to loosening and failure. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a fixing fixture for machining motor stator and rotor laminations, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fixing fixture for machining motor stator and rotor laminations, comprising a motor stator and rotor progressive die and a T-bolt, wherein a support base is connected to the surface of the T-bolt, and an adjustment groove is provided at the bottom of the support base; an insert block is fixed on one side of the outer surface and one side of the back of the support base, and a high-strength bolt passes through the top of the insert block; a locking nut is sleeved on the outside of both the high-strength bolt and the T-bolt; two reinforcing ribs and a diagonal brace are respectively fixed on the top of the support base.

[0007] By adopting the above technical solution, a transfer connection structure of "workbench-T-bolt-support base-high-strength bolt-mold" was constructed. The support base, as the core connecting component, can be adapted to the T-slot of the workbench through T-bolts, and can also be connected to the mold fixing slot through inserts and high-strength bolts. With the strength guarantee of reinforcing ribs and diagonal bracing blocks, the fixing problem when the mold fixing slot and the T-slot of the workbench are misaligned is effectively solved, and stable connection and precise stamping are achieved in misalignment scenarios.

[0008] Furthermore, the support base is slidably connected to the T-bolt via an adjustment groove.

[0009] By adopting the above technical solution, the support base can move freely in the lateral direction of the T-bolt, which facilitates flexible adjustment of its position according to the actual misalignment distance between the fixing groove and the T-groove. This ensures that the insert and high-strength bolt can be accurately aligned with the fixing groove, improves the adaptability of the tooling to different misalignment ranges, and avoids installation difficulties caused by positional deviations.

[0010] Furthermore, the high-strength bolts are fixedly connected to the insert block by means of inlaying and welding.

[0011] By adopting the above technical solution, the high-strength bolt and the insert block form a rigid whole, which not only prevents the bolt from loosening and falling off during stamping vibration, but also enhances the cooperative force-bearing capacity of the two, ensuring that the high-strength bolt can stably transmit the locking force and improve the connection reliability between the mold and the support base.

[0012] Furthermore, the two inserts and the high-strength bolts are diagonally distributed.

[0013] By adopting the above technical solution, it can be used in both left and right offset scenes, increasing flexibility and making it suitable for more scenarios, thus demonstrating good practicality.

[0014] Furthermore, the outer surface and back of the motor stator and rotor progressive mold are provided with several fixing grooves.

[0015] By adopting the above technical solution, multiple connection points are provided for the mold, which can not only adapt to the fixing requirements of molds of different specifications, but also connect through other slots when a certain fixing slot cannot be used, thereby improving the adaptability of the mold and tooling and avoiding fixing problems caused by the failure of a single slot.

[0016] Furthermore, the insert is adapted to the lower part of the fixing groove.

[0017] By adopting the above technical solution, the insert block can be accurately embedded into the bottom of the fixing groove to form a stable support and positioning, preventing the mold from moving longitudinally or shifting laterally during the stamping process. At the same time, it provides a force support point for the high-strength bolt, ensuring that the locking force can be effectively applied to the mold.

[0018] Furthermore, the locking nut is a single flange nut or a combination of a flange nut and a regular nut.

[0019] By adopting the above technical solution, a single flange nut can achieve basic anti-loosening by utilizing the anti-slip teeth on the flange surface, while the combined structure forms mechanical anti-loosening through double nut pre-tightening, adapting to the locking requirements under different stamping strengths, avoiding nut loosening caused by long-term vibration, and ensuring connection stability.

[0020] Furthermore, the support base, reinforcing ribs, and diagonal bracing blocks are made of 45 steel or 55 steel.

[0021] By adopting the above technical solution, the support base of the motor stator and rotor progressive die has good comprehensive mechanical properties and can meet the requirements of bearing certain pressure and shear force during operation. During the stamping process of the progressive die, there will be a certain impact force. The toughness of 45 steel can prevent the support base from breaking suddenly. 55 steel has a higher carbon content than 45 steel. After appropriate heat treatment, it can obtain higher strength and hardness. In the motor stator and rotor progressive die, the support base needs to withstand the pressure, shear force and other loads generated during the operation of the die. The higher strength and hardness of 55 steel can better resist deformation, ensure the stability and precision of the die, and extend the service life of the die. However, its impact resistance is not as good as that of 45 steel. Therefore, in practical applications, 45 steel is selected for long-term use when the impact and vibration are large, and 55 steel is selected for long-term use when the impact and vibration are small.

[0022] Furthermore, the reinforcing ribs are fixedly connected to the support base by welding, and the diagonal bracing blocks are fixedly connected to the support base by integral molding.

[0023] By adopting the above technical solution, the welded reinforcing ribs can enhance the longitudinal bending resistance of the support base, while the integrally formed diagonal brace blocks form a seamless triangular stable structure with the support base. The two work together to improve the overall rigidity of the support base, effectively disperse the stamping load, and prevent the support base from bending and deforming due to excessive force.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model, through the design of T-bolts, support seats, and adjustment grooves, allows the T-bolts to be embedded in the T-slots of the worktable, and the support seats to slide on the T-bolts via the adjustment grooves. This enables flexible adjustment of the lateral position of the support seats, ensuring precise alignment of the high-strength bolts and inserts with the fixing grooves. This effectively solves the problem of misalignment of grooves caused by processing errors and installation deviations, eliminating the need for secondary processing of the mold or worktable and significantly improving the adaptability and efficiency of mold installation. It also achieves a misaligned connection between the T-slots of the worktable and the mold fixing grooves, capable of handling most misalignment situations.

[0026] 2. This utility model, through the setting of insert blocks and high-strength bolts, adapts the insert blocks to the lower part of the mold fixing groove, and with the locking force of the high-strength bolts, and since the two insert blocks and high-strength bolts are diagonally distributed, they can provide stable support and fixation for the mold from both the front and the back. Therefore, it can cope with the situation of the mold fixing groove shifting to the left, and can also adapt to the scenario of shifting to the right, ensuring that the mold does not shake or shift during the stamping process, thus ensuring the processing accuracy of the stator and rotor laminations; and enhancing the stability of the connection between the mold and the support base.

[0027] 3. This utility model, through the setting of reinforcing ribs and diagonal bracing blocks, with the reinforcing ribs fixed to the support base by welding and the diagonal bracing blocks being integrally formed and connected to the support base, and the support base, reinforcing ribs, and diagonal bracing blocks all being made of 45 steel or 55 steel, can effectively disperse the impact force and torque transmitted to the support base by the die during the stamping process, avoid the support base from bending and deforming due to excessive force, extend the service life of the tooling, and ensure the connection stability during long-term use, further improving the safety and reliability of the overall tooling; and significantly improving the structural strength and bending resistance of the support base.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0036] The embodiments of this utility model will be described below based on its overall structure.

[0037] Example 1:

[0038] A fixture for machining motor stator and rotor laminations, such as Figures 1-5 As shown, the device includes a progressive die 1 for the motor stator and rotor and a T-bolt 3. A support base 4 is connected to the surface of the T-bolt 3. An adjustment groove 10 is provided at the bottom of the support base 4. The support base 4 is slidably connected to the T-bolt 3 through the adjustment groove 10. Insert blocks 7 are fixed on one side of the outer surface and one side of the back of the support base 4. The insert blocks 7 are adapted to the lower part of the fixed groove 2. A high-strength bolt 8 passes through the top of the insert block 7. The high-strength bolt 8 is fixedly connected to the insert block 7 by embedding and welding. The two insert blocks 7 and the high-strength bolt 8 are diagonally distributed. Locking nuts 9 are sleeved on the outside of the high-strength bolt 8 and the T-bolt 3. The support base 4 is slidably connected to the T-bolt 3 through the adjustment groove 10. The operator can push the support base 4 laterally along the adjustment groove 10 according to the actual misalignment between the fixed groove 2 and the T-groove until the insert blocks 7 on the outer surface and back of the support base 4 are aligned with the fixed groove 2 of the die. Then, the operator inserts the insert blocks 7 into the fixed groove 2 and moves the high-strength bolt 8 into the fixed groove 2. Then, the workers first use the locking nut 9 and T-bolt 3 to limit the support base 4, and then use the locking nut 9 and high-strength bolt 8 to limit the motor stator and rotor progressive die 1. The axial locking force of the high-strength bolt 8 is used to rigidly fix the die to the support base 4, while the T-bolt 3 is fastened to the support base 4 and the worktable through the locking nut 9. Two reinforcing ribs 5 and diagonal bracing blocks 6 are fixed to the top of the support base 4. The support base 4, reinforcing ribs 5 and diagonal bracing blocks 6 are made of 45 steel or 55 steel. The reinforcing ribs 5 are fixed to the support base 4 by welding, and the diagonal bracing blocks 6 are fixed to the support base 4 by integral molding. During the stamping process, the longitudinal impact force on the die is transmitted to the support base 4 through the insert block 7. The reinforcing ribs 5 at the top of the support base 4 form a longitudinal support structure by welding, and the diagonal bracing blocks 6 form a triangular stable structure with the support base 4 by integral molding. The two together disperse the impact force and prevent the support base 4 from deforming due to excessive bending moment.

[0039] See Figure 1 In the above embodiments, the outer surface and back of the motor stator and rotor progressive mold 1 are provided with several fixing grooves 2 to facilitate locking and limiting. Since the stator and rotor progressive mold 1 is a customized component, the specific style and structure of the motor stator and rotor progressive mold 1 are not described in detail in the figures and text.

[0040] Example 2:

[0041] To address the technical problem of its inapplicability to short-span misalignment, this embodiment is an improvement upon Embodiment 1. In this embodiment, please refer to... Figure 6The difference between the second embodiment and the first embodiment lies in the structure and size of the support base 4: the length of the support base 4 in the second embodiment is significantly shortened, and only the top reinforcing rib 5 is retained, while the diagonal brace 6 is eliminated. The overall structure is simpler and lighter, and it is suitable for scenarios where the misalignment span between the T-slot and the fixed slot 2 is small.

[0042] Example 3:

[0043] Based on the above embodiment one, the following settings are now made to increase the locking strength.

[0044] See Figures 1-6 In the above embodiments, the locking nut 9 is a single flange nut or a combination of a flange nut and a regular nut. In the prior art, those skilled in the art often use a single flange nut as the locking nut 9 to lock the motor stator and rotor progressive mold 1. An additional regular nut is added to the flange nut. The double-nut mechanical anti-loosening structure improves the vibration resistance, reduces the risk of loosening during long-term use, and ensures production safety.

[0045] The implementation principle of this utility model is as follows: First, during installation, if the fixing groove 2 can be aligned with the T-slot on the workbench, the operator directly uses the T-bolt 3 in conjunction with the locking nut 9 to lock and limit the motor stator and rotor progressive mold 1; if the fixing groove 2 cannot be aligned with the T-slot on the workbench, the operator first inserts the bottom end of the T-bolt 3 into the preset T-slot on the workbench; there are two types of support base 4. Figures 1 to 5 The support base 4 in Embodiment 1 has reinforcing ribs 5 and diagonal bracing blocks 6, and is suitable for scenarios where the T-slot and the fixed slot 2 deviate by a large span. Figure 6 The support base 4 in Embodiment 2 has only reinforcing ribs 5, but its length is much smaller than that of the support base 4 in Embodiment 1. It is suitable for scenarios where the deviation between the T-slot and the fixed slot 2 is small. The support base 4 is slidably connected to the T-bolt 3 through the adjustment groove 10. The operator can push the support base 4 laterally along the adjustment groove 10 according to the actual misalignment between the fixed slot 2 and the T-slot until the insert 7 on the outer surface and back of the support base 4 is aligned with the fixed slot 2 of the mold. Then, the operator inserts the insert 7 into the fixed slot 2 and puts the high-strength bolt 8 into the fixed slot 2. Then, the operator first uses the locking nut 9 in conjunction with the T-bolt 3 to limit the support base 4, and then uses the locking nut 9 in conjunction with the high-strength bolt 8 to limit the motor stator and rotor progressive mold 1. The axial locking force of the high-strength bolt 8 is used to rigidly fix the mold and the support base 4, while the T-bolt 3 is fastened to the support base 4 and the worktable through the locking nut 9.

[0046] During the stamping process, the longitudinal impact force on the die is transmitted to the support base 4 through the insert block 7. The reinforcing rib 5 at the top of the support base 4 is welded to form a longitudinal support structure. The inclined support block 6 is integrally formed with the support base 4 to form a triangular stable structure. The two together disperse the impact force and prevent the support base 4 from deforming due to excessive bending moment.

[0047] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
