[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] The following further elaborates on this application in conjunction with the attached Figures 1-4 drawings to provide a more detailed description of the present application.

[0028] An embodiment of the present application discloses a temperature measurement hole drilling and milling device for a motor bearing seat in a mining machine, including a drilling and milling machine 100 and a positioning tooling 200. The drilling and milling machine 100 is used to cooperate in drilling and milling a temperature measurement hole in the bearing seat 300. The drilling and milling machine 100 includes a bracket 500 that moves longitudinally along a drilling and milling platform 400, a transverse lead screw module 2 provided on the bracket 500, a vertical lead screw module 4 fixedly connected to a transverse moving seat 3 on the transverse lead screw module 2, an electric rotary table A6 fixedly connected to a vertical moving seat 5 on the vertical lead screw module 4, and an electric drill 7 driven to rotate by the electric rotary table A6; the drilling and milling platform 400 has an inverted U-shaped structure, and a longitudinal lead screw module 8 is installed on the drilling and milling platform 400. Both ends of a longitudinal moving seat 9 on the longitudinal lead screw module 8 are fixedly connected to the bracket 500. Both ends of the longitudinal moving seat 9 are respectively in sliding guide fit with longitudinal guide rails 10 inside the drilling and milling platform 400. The bracket 500 is composed of two side plates that are vertically and rearwardly inclined.

[0029] A C-shaped support L11 is fixedly provided on the rotating disk of the electric rotary table A6, and the electric drill 7 is fixed on the horizontal plate of the C-shaped support L11.

[0030] The C-shaped support L11 provides a fixed position, making the installation and replacement of the electric drill 7 faster and more convenient. The electric drill 7 is fixed on the C-shaped support L11, and better support can be obtained, thereby enhancing the stability during the operation process.

[0031] When the longitudinal lead screw module 8 operates, it drives the bracket 500 to move longitudinally. The inverted U-shaped structure provides strong support and fixation, which helps to maintain the stability of the platform during the entire drilling and milling process and reduce machining errors caused by vibration.

[0032] The longitudinal lead screw module 8 enables the longitudinal moving seat 9 to achieve precise longitudinal movement on the drilling and milling platform 400. This design is usually equipped with precise guide rails, further improving the accuracy of movement and the accuracy of repeated positioning.

[0033] The two side plates are inclined rearward, which can improve the stability of the entire device to a certain extent and reduce shaking or movement caused by the action of gravity. This design helps to optimize the spatial layout, enabling the device to provide sufficient stability and support while not occupying too much space.

[0034] The longitudinally moving bracket 500, the transverse lead screw module 2, the vertical lead screw module 4 and the electric rotary table A6 are used in cooperation to drive the rotating electric drill 7 to move longitudinally, transversely and vertically, and can also drive the electric drill 7 to rotate, jointly providing precise positioning and multi-dimensional movement capabilities for the electric drill 7.

[0035] The positioning tooling 200 is used to cooperate with the clamping and positioning of the bearing housing 300. The positioning tooling 200 includes an L-shaped support A12, a rectangular groove 13 fixed on the L-shaped support A12 and for placing the bearing housing 300 in cooperation, an inverted L-shaped support 14 fixed above the side plate of the L-shaped support A12, and a downward hydraulic rod 15 fixed on the inverted L-shaped support 14 and for press-fitting and fixing the bearing housing 300 in the rectangular groove 13.

[0036] A lower pressing plate 16 for press-fitting and fixing the bearing housing 300 in the rectangular groove 13 is fixedly provided at the end of the hydraulic rod of the downward hydraulic rod 15.

[0037] The design of the lower pressing plate 16 can quickly press-fit and fix the bearing housing 300 in the rectangular groove 13, improving the speed of positioning and fixing. The lower pressing plate 16 driven by the hydraulic rod can provide uniform pressure, ensuring the stability and safety of the bearing housing 300 during the drilling process.

[0038] The L-shaped support A12 is fixed on the rotating disk of the electric rotary table B17. The electric rotary table B17 is fixed on the side plate of the L-shaped support B18. The L-shaped support B18 is fixed on the rotating table of the electric rotary table C19. The electric rotary table C19 is fixed on the drilling and milling platform 400.

[0039] The bearing housing 300 is placed in the rectangular groove 13. The downward hydraulic rod 15 moves downward from above the rectangular groove 13 and the bearing housing 300 to press-fit and fix the bearing housing 300 in the rectangular groove 13 for positioning the bearing housing 300, achieving stable positioning. This hydraulic positioning method can not only quickly and accurately position the bearing housing 300, but also ensure the stability of the bearing housing 300 during the drilling process, avoiding drilling deviation caused by vibration or movement.

[0040] Through the stacked arrangement of multiple electric rotary tables, multi-dimensional adjustment of the bearing housing 300 can be achieved, facilitating the bearing housing 300 to face the electric drill 7 at different angles, which is convenient for drilling and milling the temperature measurement holes.

[0041] Drilling and milling the temperature measurement holes is to obtain the temperature distribution of the bearing housing 300, and then monitor its working state and performance. Precise drilling positions and stable positioning can ensure the accuracy and consistency of the temperature measurement holes, providing reliable data for subsequent temperature monitoring. Through multi-dimensional movement and precise positioning, the drilling task can be completed quickly and accurately, improving work efficiency. Accurate positioning and stable movement ensure the position and quality of the holes, improving the machining accuracy. Hydraulic positioning is fast and reliable, ensuring the stability of the workpiece during the machining process, reducing the operation risk. The rectangular groove 13 can be disassembled and replaced to adapt to the placement of different bearing housings 300. This design can adapt to bearing housings 300 of different models and sizes, having good versatility.
