DETAILED DESCRIPTION

[0024] The following is a detailed description of an auxiliary device for welding the teeth of a mining crusher provided by the utility model in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some known technologies, those skilled in the art may also adopt other alternative methods to implement them; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the utility model.

[0025] like Figure 1 - Figure 3 As shown, an embodiment of the utility model provides an auxiliary device for welding mining crusher teeth, including: a base 1, with two positioning plates 2 symmetrically arranged at the top two ends; two rotating seats 5, which are provided and rotatably connected between the two positioning plates 2 in opposite directions; a clamping rod 6, which is provided in plurality and distributed in a ring array and fixedly connected to the two rotating seats 5 to form a cage-like structure for fixedly installing the crusher teeth; a motor 4, which is fixed to the outside of one of the positioning plates 2, and the output end is fixedly connected to one of the rotating seats 5 for driving the rotating seat 5 to rotate; a pedal assembly 7, which is arranged on the base 1 and is used to control the forward and reverse rotation of the motor 4.

[0026] The base 1 is the foundation of the entire device, and its stability is directly related to the safety of the welding operation. The base 1 is made of high-strength material to ensure that there is no displacement or deformation during the welding process of the heavy crusher teeth; the positioning plates 2 are symmetrically arranged at both ends of the top of the base 1, which not only enhances the stability of the overall structure, but also accurately defines the rotation trajectory of the rotating seat 5, ensuring the precise alignment of the teeth during the welding process.

[0027] The crusher teeth are fixed by a cage-like tooling structure composed of two rotating seats 5 and multiple clamping rods 6. When the tooling is fixed, the outer side wall of the teeth is clamped and fixed by multiple clamping rods 6 to be positioned. This is suitable for tooling with a distance between the two rotating seats 5 that does not exceed the distance between them. The tooling structure is driven to rotate by a motor 4, and no manual operation is required, thereby improving the convenience of the auxiliary device.

[0028] like Figure 3 As shown, the rotating seat 5 is a disc-shaped structure, and a plurality of mounting grooves 51 distributed in a circular array are provided at the outer edge positions of the opposite sides of the rotating seat 5, and threaded holes are provided at the bottom positions of the mounting grooves 51 for threaded connection bolts; there are no less than three clamping rods 6, and mounting rods 61 are provided at both ends of the clamping rods 6, and the mounting rods 61 are slidably connected with the mounting grooves 51, and through holes are provided on the mounting rods 61 for slidably connecting bolts.

[0029] Among them, the disc-shaped design of the rotating seat 5, combined with the annular array mounting groove 51 thereon, provides a plurality of adjustable fixing points for the clamping rod 6. This design enables crusher teeth of different sizes and shapes to be firmly clamped, and has strong adaptability. The number of clamping rods 6 is not less than three, and the sliding connection between the mounting rod 61 and the mounting groove 51 realizes the all-round fixation of the teeth. This cage-like structure not only effectively prevents the teeth from shaking during the welding process, but also ensures the consistency of the welding quality. By opening a through hole on the mounting rod 61 and connecting it with the threaded hole of the mounting groove 51 with a bolt, the clamping rod 6 can be quickly installed and disassembled, thereby improving work efficiency.

[0030] like Figure 1 As shown, it also includes a fixing plate 3, which is vertically fixedly connected to the outer side of one of the positioning plates 2 and is used for fixing and installing a motor 4; the motor 4 adopts a high-precision servo motor to improve the operation accuracy.

[0031] Among them, the motor 4 adopts a high-precision servo motor, which has the characteristics of fast response speed and high control accuracy. It can accurately control the rotation speed and direction of the rotating seat 5 to meet the needs of different welding processes; the design of the fixed plate 3 ensures the stable installation of the motor 4, reduces vibration and noise, and extends the service life of the motor 4.

[0032] like Figure 1 As shown, two pedal assemblies 7 are provided and are symmetrically arranged at two ends of one side of the top of the base 1, and are used to control the forward and reverse rotation of the motor 4 respectively.

[0033] The provision of the foot pedal assembly 7 greatly facilitates the operator's control. By stepping on the two foot pedal switches 74 respectively, the forward and reverse rotation of the motor 4 can be controlled without frequent switching of hand operations, thereby improving the safety and efficiency of the operation.

[0034] Among them, the motor 4 is electrically connected to the pedal assembly 7 through the motor controller. The motor controller can send instructions through PLC programming to realize the forward and reverse rotation and rotation angle control of the motor 4. The single rotation angle of the motor 4 is determined according to the different numbers of teeth of the blade, and the forward and reverse rotation of the motor 4 is controlled by pressing different pedal assemblies 7.

[0035] Furthermore, the motor 4 is also equipped with an encoder for real-time monitoring of the rotation angle of the output shaft of the motor 4. When an error is detected in the rotation angle of the motor 4, automatic calibration can be performed quickly.

[0036] like Figure 2 As shown, the foot pedal assembly 7 includes: a lifting seat 71, fixed on the top of the base 1, for lifting the operating platform; a foot switch 74, arranged on the top of the lifting seat 71; a protective shed 73, fixed above the lifting seat 71 through a back plate 72, and there is a gap between the protective shed 73 and the foot switch 74 to facilitate pressing the foot switch 74.

[0037] By setting the lifting seat 71, the foot switch 74 protrudes from the top of the base 1 to avoid accidental touch. By setting the protective shed 73, impurities such as iron filings generated during welding are prevented from splashing and adhering to the foot switch 74, which plays a certain protective role.

[0038] The technical solution provided by the utility model, when actually used, firstly, according to the size and shape of the crusher teeth to be welded, select the appropriate number of clamping rods 6 and prepare the required bolts and other fasteners; then, fix two of the clamping rods 6 between the two rotating seats 5, and rotate the rotating seats 5 so that the two installed clamping rods 6 are located below the axes of the two rotating seats 5, and then place the teeth on the two clamping rods 6 between the two rotating seats 5, and then install the remaining clamping rods 6, and calibrate the bolts for installing each clamping rod 6 so that the tooling axis of the teeth is parallel to the central axes of the two rotating seats 5, start the motor 4 (it can be tested briefly through the pedal assembly 7) for debugging, and observe whether the teeth are stable without shaking, and whether the rotation is smooth. If necessary, adjust the position or tightness of the clamping rod 6 again to ensure that the cutter teeth are in the optimal position for welding, and adjust the initial rotation angle of the motor 4 according to the welding process requirements. After confirmation, start welding. During the welding process, when the cutter tooth angle needs to be adjusted, step on the foot switch 74, send instructions through the motor controller, and the motor 4 is precisely controlled by a high-precision servo motor to drive the rotating seat 5 and the clamping rod 6 to rotate according to the preset rotation speed and direction, driving the cutter teeth to rotate at a predetermined angle. The encoder configured for the motor 4 monitors the rotation angle of the output shaft in real time to ensure the rotation accuracy, and automatically calibrates when necessary. When rework is required, the last rotation angle of the cutter teeth can be reset by stepping on another foot switch 74.

[0039] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
