Description

Technical Field

[0001] The utility model belongs to the technical field of dove tail reinforcement welding, in particular to a local temperature collection device for dove tail reinforcement welding. Background Art

[0002] During the welding of stator dovetail reinforcement, elastic elements are often used to assist. These elements not only effectively prevent warping of the stator core and frame due to stator core expansion, but also utilize the frame's rigidity to reduce stator core vibration. The elastic elements require high precision adjustment, and the welding process is done using argon arc welding, which concentrates heat energy and significantly impacts overall data. To minimize deformation, temperature monitoring and collection are necessary during the dovetail reinforcement welding process.

[0003] Traditional local temperature monitoring of dovetail bars usually uses fixed-position temperature sensors, but this limits the comprehensive understanding of temperature changes at different locations in the welding area. At the same time, fixed temperature sensors cannot be moved to the optimal temperature measurement position according to actual needs, reducing the accuracy of temperature monitoring. Utility Model Content

[0004] The purpose of the utility model is to provide a local temperature collection device for dovetail reinforcement welding to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a local temperature acquisition device for dovetail reinforcement welding, comprising:

The two spring positioning plates are respectively fixedly connected to the F-shaped clamping plate and the opposite side surfaces of the downward pressure fastening plate, so that the downward pressure spring presses the downward pressure fastening plate downward to clamp the U-shaped adjustment tooling.

[0016] In this solution, the lower side wall of the F-type card plate is integrally connected with an extended horizontal plate, and the electric guide rail part is fixed on the outer wall of the extended horizontal plate.

[0029] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0030] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.

[0031] This embodiment provides Figures 1 to 4 The local temperature collection device for dovetail reinforcement welding shown includes: a dovetail reinforcement welding tooling assembly 1, a dovetail reinforcement elastic part 4, and a local temperature collection component 7.

[0032] In this embodiment, the dove tail reinforcement welding tooling assembly 1 is used for local temperature collection during the dove tail reinforcement welding process. The dove tail reinforcement welding tooling assembly 1 includes a welding table 2 installed on the welding equipment and an inverted U-shaped adjustment tooling 5 arranged on the top surface of the welding table 2; a dove tail reinforcement support plate 3 is arranged on the top surface of the welding table 2 and located below the U-shaped adjustment tooling 5, and the dove tail reinforcement elastic part 4 is embedded in the dove tail reinforcement support plate 3.

[0033] In this embodiment, the dovetail rib elastic member 4 is arranged in the U-shaped adjustment tooling 5 and is clamped on the dovetail groove; the dovetail rib elastic member 4 is used to adapt to dovetail ribs of different sizes or shapes, and ensures good contact and fixation of the dovetail rib through elastic deformation.

[0034] In this embodiment, the local temperature collection assembly 7 is used to collect the temperature of the dovetail rib elastic member 4 inside the U-shaped adjustment fixture 5 during the welding of the dovetail rib. The local temperature collection assembly 7 includes an F-shaped card plate 6 that is clamped to the upper outer wall of the U-shaped adjustment fixture 5, an electric guide rail 16 fixed to the lower part of the F-shaped card plate 6, a slider 17 that is slidably connected to the electric guide rail 16, and a temperature sensor 18 installed at the end of the slider 17. The F-shaped card plate 6 serves as the installation base of the local temperature collection assembly 7, and it may also serve as an auxiliary positioning or other functions. The combination of the electric guide rail 16 and the slider 17 enables the temperature sensor 18 to move along a predetermined path to perform multi-point temperature detection. A first handle 8 is symmetrically welded to the top surface of the F-shaped card plate 6, and a second handle 20 is welded to the outer wall of the lower pressure fastening plate 13. The electric guide rail member 16 includes a guide rail motor embedded in the lower side of the F-shaped card member 6 and a screw rotatably mounted in the housing of the electric guide rail member 16. The screw thread penetrates the slider member 17, so that when the guide rail motor drives the screw to rotate, the screw can drive the slider member 17 to move linearly. The guide rail motor is a forward and reverse motor.

[0035] In this embodiment, the monitoring end of temperature sensor 18 extends into the interior of U-shaped adjustment fixture 5 and is movable on one side of the dovetail elastic member 4 to collect the temperature at different locations of the dovetail elastic member 4. Temperature sensor 18 directly senses the temperature of the welding area and transmits the data to the control system for analysis and processing.

[0036] In this embodiment, the clamping base plate 14 integrally connected to the inside of the F-shaped clamping plate 6 is clamped against the inner top wall of the U-shaped adjustment tooling 5, and a clamping installation area 19 for clamping the U-shaped adjustment tooling 5 is set between the top of the F-shaped clamping plate 6 and the clamping base plate 14.

[0037] In this embodiment, a downward pressing fastening plate 13 is slidably connected in the clamping installation area 19, and both ends of the downward pressing fastening plate 13 close to the inner wall of the F-type clamping plate 6 are integrally connected with L-type clamping blocks 23 arranged in opposite directions. The two L-type clamping blocks 23 are relatively clamped on the outer walls on both sides of the F-type clamping plate 6.

[0038] In this embodiment, the ends of the two L-shaped clamping blocks 23 away from the downward pressing fastening plate 13 are connected to a detachable pressure plate 24 via a locking bolt 25. The detachable pressure plate 24 is clamped to the back of the F-shaped clamping plate 6, so that the L-shaped clamping block 23 and the detachable pressure plate 24 can be clamped and slid on both sides of the F-shaped clamping plate 6. The detachable pressure plate 24 strengthens the clamping force of the L-shaped clamping block 23 on the F-shaped clamping plate 6 and facilitates removal and replacement during maintenance.

[0039] In this embodiment, rolling steel balls 26 are embedded in the inner walls of both L-shaped blocks 23. When the L-shaped blocks 23 are clamped on the F-shaped card plate 6, the rolling steel balls 26 engage in rolling friction with the outer wall of the F-shaped card plate 6. The rolling steel balls 26 reduce wear caused by friction between the L-shaped blocks 23 and the F-shaped card plate 6, and also reduce movement resistance, making adjustment smoother.

[0040] In this embodiment, the hold-down fastening plate 13 is pressed down on the top surface of the U-shaped adjustment fixture 5. An adjusting screw 9 is longitudinally connected to the middle position of the top surface of the F-shaped clamping member 6. The bottom screw end of the adjusting screw 9 is pressed down on the top surface of the hold-down fastening plate 13. The free end of the adjusting screw 9 abuts the top surface of the hold-down fastening plate 13 and is not threadedly connected thereto.

[0041] In this embodiment, downward pressure springs 22 are provided on the top surface of the downward pressure fastening plate 13 and at diagonally opposite positions. A spring positioning disc 21 is fixed to the upper and lower ends of each downward pressure spring 22. The two spring positioning discs 21 are respectively fixedly connected to the F-shaped clamping member 6 and the opposite side of the downward pressure fastening plate 13. This allows the downward pressure springs 22 to press the downward pressure fastening plate 13 downward to clamp the U-shaped adjustment fixture 5. The spring positioning discs 21 cooperate with the downward pressure springs 22 to ensure that the downward pressure fastening plate 13 maintains appropriate pressure distribution.

[0042] In this embodiment, the lower side wall of the F-type card plate 6 is integrally connected to the extension horizontal plate 15, and the electric guide rail part 16 is fixed on the outer wall of the extension horizontal plate 15. The extension horizontal plate 15 drives the electric guide rail part 16 to be located on one side of the dove tail rib elastic part 4 and the electric guide rail part 16 faces the dove tail rib elastic part 4.

[0043] In this embodiment, a control terminal 10 is integrally connected to the outer wall of one side of the upper portion of the F-shaped card plate 6 . The top of the control terminal 10 has an LED screen 11 , and the top surface of one side of the control terminal 10 has a control button 12 .

[0044] In this embodiment, the temperature sensor 18 sends the collected temperature signal to the PLC unit inside the control terminal 10 through the communication unit. The PLC unit parses the signal data and displays it to the user on the LED screen 11 according to a predetermined format.

[0045] Working principle:

[0046] The local temperature collection device for dovetail reinforcement welding places the dovetail reinforcement to be welded on the dovetail reinforcement support plate 3, and adjusts the U-shaped adjustment tool 5 manually or automatically so that the dovetail reinforcement elastic part 4 is accurately clipped into the dovetail groove. The first handle 8 and the second handle 20 are used to assist in preliminary position calibration to ensure that the F-shaped clip part 6 is firmly installed above the U-shaped adjustment tool 5, and the clip-on bottom plate 14 is close to its inner top wall.

[0047] Adjust the position of the downward pressure fastening plate 13 so that it can evenly apply pressure to the top of the U-shaped adjustment tooling 5. Use the adjusting screw 9 to fine-tune the downward pressure so that the downward pressure fastening plate 13 clamps the U-shaped adjustment tooling 5 and fixes the F-shaped card plate 6. The downward pressure spring 22 and the spring positioning plates 21 fixed at both ends help maintain a constant pressure distribution. The L block 23 is connected to the detachable pressure plate 24 through the locking bolt 25 to enhance the stability of the overall structure; the rolling steel ball 26 reduces friction and facilitates adjustment.

[0048] The local temperature acquisition component 7 is installed and fixed on the F-type card plate 6, and the temperature sensor 18 is installed on the slider 17, which can move freely on the electric guide rail 16. The required temperature detection parameters are set by the control button 12, and the PLC unit in the control terminal 10 is ready to receive data from the temperature sensor 18.

[0049] Start the welding equipment and start welding the dovetail reinforcement. During the welding process, the temperature sensor 18 moves along the electric guide rail 16 according to the predetermined path, continuously collecting temperature data at different points in the welding area. The collected temperature signals are transmitted to the PLC unit in the control terminal 10 through the communication unit. After parsing the data, the PLC unit converts it into an easy-to-understand information format and displays it to the operator in real time through the LED screen 11. Based on the temperature reading on the LED screen 11, the operator can judge whether the current welding status meets the expectations. If an abnormal temperature rise is found, the operator can take immediate measures through the control button 12, such as pausing the welding process or adjusting the welding parameters.

[0050] After welding is completed, turn off the welding power supply and loosen all locking mechanisms, including the adjusting screw 9, L block 23, etc., so as to remove the welded dovetail reinforcement and perform necessary cleaning and maintenance on the device to prepare for the next use.
