Description

Technical Field

[0001] This utility model relates to the field of servo motor technology, specifically a multi-axis synchronous servo motor with pressure regulation function. Background Technology

[0002] Multi-axis synchronous servo motors are collaborative control systems composed of multiple servo motors. They achieve high-precision synchronous operation of position, speed or torque between axes through electrical signals. The core of the system is to enable multiple independently driven servo units to maintain dynamic coordination under complex loads through master-slave control, coupling algorithms or bus communication technology. It can be applied to high-precision automation scenarios such as printing machinery and industrial robots.

[0003] However, existing multi-axis synchronous servo motors still have certain problems in use:

[0004] For example, a servo motor for a machine tool with application number CN202020661411.6 includes a motor, a fixed cylinder is fixedly connected to the rear end of the output end of the motor, a groove is opened on the outer surface of the output end of the motor, a dust cover is fixedly connected to the outer surface of the fixed cylinder, a first through hole is opened in the middle of the outer surface of the dust cover, and a boss is fixedly connected to the bottom end of the outer surface of the dust cover.

[0005] When multi-axis synchronous servo motors are used in processes such as injection molding and stamping, traditional multi-axis synchronous servo motors lack pressure adjustment functions. This makes it impossible to guarantee the stability and accuracy of the applied pressure when mechanical parts wear out, which can easily lead to problems such as product size deviation and poor surface quality, seriously affecting production efficiency and product quality.

[0006] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0007] To address the aforementioned issues, an innovative design was implemented based on the existing multi-axis synchronous servo motor. Utility Model Content

[0008] The purpose of this invention is to provide a multi-axis synchronous servo motor with pressure regulation function to solve the problem mentioned in the background art. Traditional multi-axis synchronous servo motors lack pressure regulation function when applied to processes such as injection molding and stamping. This makes it impossible to guarantee the stability and accuracy of the applied pressure when mechanical parts wear, which can easily cause problems such as product size deviation and poor surface quality, seriously affecting production efficiency and product quality.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A multi-axis synchronous servo motor with pressure regulation function includes a motor body and an output shaft. The output shaft is provided on one side of the motor body. An embedded groove is formed on the outer surface of the output shaft. A lower clamping plate is provided on the lower surface of the output shaft and in the middle of the embedded groove. Both ends of the lower clamping plate are threaded with screw pins. An upper clamping plate corresponding to the lower clamping plate is provided on the upper surface of the output shaft. Springs are fixed at both ends of the upper clamping plate. A fastening nut is fixed at the top of the spring. A first mounting base is welded to the outer surface of the upper clamping plate. A strain gauge pressure sensor is bolted to the upper end face of the first mounting base. A wire is electrically connected to the outer surface of the strain gauge pressure sensor.

[0011] Preferably, the inner sides of the upper and lower clamping plates are both arc-shaped, and the inner sides of the upper and lower clamping plates are tightly fitted and connected to the embedded groove on the output shaft.

[0012] Using the above technical solution, an upper clamping plate and a lower clamping plate are nested on the outer surface of the motor body output shaft. The upper clamping plate and the lower clamping plate are fixed by fastening nuts and pins. The strain gauge pressure sensor is fastened to the first mounting seat of the upper clamping plate. The strain gauge pressure sensor can sense the pressure change of the output shaft, ensuring the stability and accuracy of the pressure applied by the motor during operation, thereby improving the product quality and production efficiency of the production process.

[0013] Preferably, the screw pin passes through the middle of the spring, and the fastening nut and the screw pin are connected by corresponding threads.

[0014] Using the above technical solution, the fastening nut is engaged with the spring and the screw thread. By tightening the fastening nut, the spring is compressed and the upper clamping plate is pushed downward, thereby achieving a tight fixation between the upper and lower clamping plates. This ensures the stability and reliability of the strain gauge pressure sensor installation, enabling it to sense changes in output shaft pressure in real time and accurately, and providing precise pressure signal feedback for the pressure regulation function of the multi-axis synchronous servo motor.

[0015] Preferably, a second mounting base is welded to the upper end face of the motor body, and a controller is bolted to the upper end of the second mounting base. A terminal is provided on one side of the controller, and the other end of the wire is inserted into the middle of the terminal.

[0016] With the above technical solution, the controller is fastened to the second mounting base by bolts on the motor body and connected to the controller by wires. This allows the pressure signal monitored by the sensor to be transmitted to the controller, enabling precise pressure regulation and control of the motor. This ensures that the multi-axis synchronous servo motor outputs stable pressure during operation, improving the accuracy and reliability of the equipment.

[0017] Preferably, the inner bottom of the terminal block is fixed with two sets of top plates, and the outer surface of the top plate is in a concave arc shape, and the outer surface of the other end of the wire is in close contact with the outer surface of the top plate.

[0018] By adopting the above technical solution, two sets of concave arc-shaped top plates are set at the bottom of the terminal. When the wire is inserted into the terminal, its outer surface is tightly fitted with the concave arc surface of the top plate, realizing a stable electrical connection between the wire and the terminal. This enhances the stability and reliability of the connection between the wire and the terminal, ensuring that the electrical signal transmitted by the strain gauge pressure sensor can be stably and efficiently transmitted to the controller, avoiding abnormal signal transmission due to loose connection, and ensuring the normal operation of the pressure regulation system.

[0019] Preferably, the inlet of the terminal is provided with a sleeve, and the sleeve is composed of multiple rubber plates spliced ​​together in a ring. A clamping screw is threaded through the middle of the terminal.

[0020] By adopting the above technical solution, a rubber sleeve is installed at the wire inlet of the terminal. The sleeve can prevent the wire from loosening and increase the tightness of the connection. The clamping screw can further clamp the wire to prevent it from loosening or shifting, avoid poor contact caused by external force, and ensure the stability and security of signal transmission.

[0021] Compared with the prior art, the beneficial effects of this utility model are: the multi-axis synchronous servo motor with pressure regulation function,

[0022] 1. The outer surface of the motor body output shaft is nested with an upper clamping plate and a lower clamping plate. The upper clamping plate and the lower clamping plate are fixed by fastening nuts and pins. The strain gauge pressure sensor is fastened to the first mounting seat of the upper clamping plate. The strain gauge pressure sensor can sense the pressure change of the output shaft, ensuring the stability and accuracy of the pressure applied by the motor during operation, and improving the product quality and production efficiency of the production process.

[0023] 2. On the motor body, the controller is fastened to the second mounting base by bolts and connected to the controller by wires. It can transmit the pressure signal monitored by the sensor to the controller, and can perform precise pressure regulation and control of the motor, ensuring that the multi-axis synchronous servo motor outputs stable pressure during operation, and improving the operating accuracy and reliability of the equipment.

[0024] 3. The two sets of concave arc-shaped top plates at the bottom of the terminal block can fit tightly against the outer surface of the wire. The arc structure increases the contact area, ensuring the stability of the electrical connection and the reliability of signal transmission, and ensuring that the electrical signal transmitted by the strain gauge pressure sensor can be stably and efficiently transmitted to the control.

[0025] 4. By installing a rubber sleeve at the wire inlet of the terminal, the sleeve can prevent the wire from loosening under external force. By tightening the clamping screw, the end of the clamping screw is tightly connected to the wire, which can further clamp the wire, prevent the wire from loosening or shifting, avoid poor contact caused by external force, and ensure the stability and safety of signal transmission.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1

[0034] Please see Figure 1 , Figure 2 , Figure 3 This utility model provides a technical solution:

[0035] A multi-axis synchronous servo motor with pressure regulation function includes a motor body 1 and an output shaft 2. The output shaft 2 is located on one side of the motor body 1. An embedding groove 3 is formed on the outer surface of the output shaft 2. A lower clamping plate 4 is located on the lower surface of the output shaft 2, in the middle of the embedding groove 3. Both ends of the lower clamping plate 4 are threadedly connected to screw pins 5. An upper clamping plate 6, corresponding to the lower clamping plate 4, is located on the upper surface of the output shaft 2. Springs 7 are fixed to both ends of the upper clamping plate 6, and fastening nuts 8 are fixed to the top of the springs 7. A first mounting base 9 is welded to the outer surface of the upper clamping plate 6. A strain gauge pressure sensor 10 is bolted to the upper end face of the first mounting base 9, and wires 11 are electrically connected to the outer surface of the strain gauge pressure sensor 10. The inner sides of both the upper clamping plate 6 and the lower clamping plate 4 are arc-shaped and are tightly fitted to the embedding groove 3 on the output shaft 2. The screw pins 5 pass through the middle of the springs 7, and the fastening nuts 8 are threadedly fastened to the screw pins 5.

[0036] This multi-axis synchronous servo motor with pressure regulation function has an embedded groove 3 on the outer surface of the output shaft 2. The lower clamping plate 4 is fixed to the middle of the embedded groove 3 on the lower surface of the output shaft 2 by a threaded pin 5 that passes through both ends. The upper clamping plate 6 is correspondingly set on the upper surface of the output shaft 2, and springs 7 fixed at both ends are sleeved on the pins 5. The fastening nut 8 at the top of the spring 7 is threadedly fastened to the pin 5. When the fastening nut 8 is tightened, the spring 7 is compressed, which drives the upper clamping plate 6 to press downward, so that the arc-shaped surfaces of the inner sides of the upper clamping plate 6 and the lower clamping plate 4 are tightly fitted with the embedded groove 3 of the output shaft 2, thereby clamping the upper clamping plate 6. Plate 6 is securely mounted on output shaft 2. The first mounting seat 9 welded to the outer surface of upper clamp plate 6 is used for bolting strain gauge pressure sensor 10. When output shaft 2 is subjected to force, strain gauge pressure sensor 10 can sense pressure changes and transmit signals through the electrically connected wires 11. This enables stable installation and accurate pressure monitoring of strain gauge pressure sensor 10, providing accurate data support for motor pressure regulation function, ensuring the stability and accuracy of pressure output during motor operation, effectively solving the problem of lack of pressure regulation function in traditional multi-axis synchronous servo motors, and improving production efficiency and product quality.

[0037] Example 2

[0038] Please see Figure 4 , Figure 5 This utility model provides a technical solution:

[0039] A second mounting base 12 is welded to the upper end face of the motor body 1. A controller 13 is bolted to the upper end of the second mounting base 12. A terminal 14 is provided on one side of the controller 13, and the other end of the wire 11 is inserted into the middle of the terminal 14. Two sets of top plates 15 are fixed to the inner bottom of the terminal 14, and the outer surface of the top plate 15 is concave arc-shaped. The outer surface of the other end of the wire 11 is in close contact with the outer surface of the top plate 15. A sleeve 16 is provided at the wire inlet of the terminal 14, and the sleeve 16 is composed of multiple rubber plates spliced ​​in a ring. A clamping screw 17 is threaded through and connected to the middle of the terminal 14.

[0040] This multi-axis synchronous servo motor with pressure regulation function has a second mounting base 12 welded to the upper end of the motor body 1. The controller 13 is securely mounted on the upper end of the second mounting base 12 by bolts. A terminal 14 on one side of the controller 13 is used to connect the wire 11. When the other end of the wire 11 is inserted into the middle of the terminal 14, the two sets of concave arc-shaped top plates 15 at the bottom of the terminal 14 can fit tightly against the outer surface of the wire 11. The arc structure increases the contact area, ensuring the stability of the electrical connection and the reliability of signal transmission. At the same time, the wire inlet of the terminal 14 is made of multiple rubber plates arranged in a ring. The clamp 16, which is formed by the connection, retracts to clamp the wire 11, and in conjunction with tightening the clamping screw 17 that passes through the middle of the terminal 14, prevents the wire 11 from loosening or shifting. On the other hand, the rubber material provides insulation, buffering, and protection, avoiding external pulling or vibration from affecting the connection effect. This ensures that the pressure signal transmitted by the strain gauge pressure sensor 10 through the wire 11 can be stably and accurately transmitted to the controller 13, providing a stable data transmission guarantee for the motor to achieve precise pressure regulation. This ensures that the motor can be effectively regulated according to the actual pressure during operation, improving the motor's working performance and reliability.

[0041] Working principle:

[0042] In use, the embedded groove 3 on the outer surface of the output shaft 2 fits tightly with the arc-shaped upper clamping plate 6 and lower clamping plate 4. The upper clamping plate 6 is securely mounted on the output shaft 2 via a threaded connection using a screw pin 5, a spring 7, and a fastening nut 8. This allows the strain gauge pressure sensor 10, fixed to the first mounting base 9 on the upper clamping plate 6, to accurately sense pressure changes on the output shaft 2 and transmit signals via a wire 11. Simultaneously, the second mounting base 12 welded to the upper end face of the motor body 1 is used for bolting the controller 13, with the other end of the wire 11 inserted into the controller 13. On one side of terminal 14, the two sets of concave arc-shaped top plates 15 on the bottom of terminal 14 fit together with the wire 11 to increase the contact area and ensure stable electrical connection. At the inlet, the sleeve 16, which is made of rubber plate ring splicing, shrinks and clamps the wire 11 after tightening the clamping screw 17. This not only prevents the wire 11 from loosening and shifting, but also uses the insulation and buffering properties of rubber to avoid external force interference, ensuring that the pressure signal of the strain gauge pressure sensor 10 can be stably and accurately transmitted to the controller 13, thereby realizing the precise adjustment and stable control of motor pressure.
