[0031] Aluminum alloy dining car window frames refer to doors and windows made from extruded aluminum alloy profiles for the frame, stiles, and sashes. These doors and windows include those with aluminum alloy as the base material for the load-bearing members, and those with wood or plastic composites, referred to as aluminum-wood composite doors and windows, and aluminum-plastic composite doors and windows. Aluminum door profiles and glass styles vary depending on the region. The north is characterized by thicker aluminum and more stable styles, with the most representative being the lattice style, and the most distinctive of these lattices being the Tang grid. The south is characterized by a variety of aluminum shapes and lively styles, with the most representative being the patterned glass style, including lattice, ice sculpture, shallow carving, and crystal shell. Aluminum alloy door and window frame processing requires milling equipment, using milling cutters to process the end faces.

[0032] In the prior art, a threaded rod is rotated by turning a handwheel. As the rod rotates, a threaded sleeve on the outer wall of the rod moves closer, driving a clamping plate to clamp and secure the window frame. Finally, a milling mechanism is used to mill the window frame. However, during use, the existing device generates a lot of metal debris during the milling process, which falls into the chute and accumulates on the surface of the threaded rod, affecting the rotation of the rod and the clamping effect of the clamping plate.

[0033] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a fixing structure for the window end face milling device. When it is necessary to mill the dining car window, the window frame is first placed on the top of the workbench 11. At this time, the motor 21 is connected to the external power supply to drive the threaded rod 1 22 to rotate. When the threaded rod 1 22 rotates, the threaded sleeve 23 is pushed downward. When the threaded sleeve 23 moves, the slider 26 is pulled through the connecting rod 24 to slide inside the slide groove 25, so that the two clamps 27 are close to clamp and fix the window frame. In order to prevent the window frame from shaking during the milling process, the threaded rod 2 32 can also be rotated so that the threaded rod 2 32 moves downward through the convex plate 31 and pushes the bottom plate 33 to move downward. The bottom plate 33 drives the pressure block 35 to slide inside the through groove 34 to press the window frame and keep it stable. Finally, the milling structure 12 is used to mill the window end face.

[0034] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0035] Combine Figure 1-Figure 4 The embodiment of the present application provides a fixing structure for a vehicle window end face milling device, comprising: a workbench 11 with a milling structure 12 arranged on the top; a clamping assembly 2 is arranged on the workbench 11, and the clamping assembly 2 comprises: a motor 21 arranged at the bottom of the motor 21; a threaded rod 22 arranged on the bottom output shaft of the motor 21; a threaded sleeve 23 sleeved on the outside of the threaded rod 22 and threadedly connected to the threaded rod 22; the bottom end of the connecting rod 24 is rotatably connected to the outer side wall of the threaded sleeve 23; a slide groove 25 is opened at the top of the workbench 11; a slider 26 is slidably arranged inside the slide groove 25, and the bottom end is rotatably connected to the top of the connecting rod 24; a splint 27 is arranged on the top of the slider 26.

[0036] Specifically, the milling mechanism 12 is an HD-X900. Its basic operating principle is to cut a workpiece using a rotating tool, with the tool's rotation serving as the primary motion and the workpiece's movement serving as the feed motion. Milling machines are capable of performing a variety of machining operations, including planes, grooves, gears, threads, and curved surfaces. Its primary cutting operations include plane milling, face milling, end milling, bevel milling, and form milling. These operations are achieved through the milling cutter's rotation and the workpiece's feed motion, resulting in the desired shape and size being machined onto the workpiece surface.

[0037] When milling a dining car window, the window frame is first placed on top of the workbench 11. The motor 21 is then connected to an external power source to drive the threaded rod 22 to rotate. As the threaded rod 22 rotates, it pushes the threaded sleeve 23 downward. As the threaded sleeve 23 moves, it pulls the slider 26 through the connecting rod 24 to slide within the slide groove 25, causing the two clamping plates 27 to close together and clamp the window frame. Finally, the milling structure 12 is used to mill the window end face. Debris generated during the milling process will not accumulate on the surface of the threaded rod 22, thereby not affecting its rotation.

[0038] In some embodiments, the slider 26 is designed in an I-shape.

[0039] The I-shaped design of the slider 26 during use allows it to be tightly connected to the slide groove 25 and not easily separated from the slide groove 25 during sliding.

[0040] In some embodiments, the clamping assembly 2 further includes: a baffle 231 disposed at the bottom of the threaded sleeve 23 .

[0041] During use, the design of the baffle 231 can prevent the threaded sleeve 23 from separating from the threaded rod 22 when moving.

[0042] In some embodiments, the clamping assembly 2 further includes: one end of a cross bar 28 passes through the slider 26 , and both ends are connected to the inner side walls of the sliding groove 25 .

[0043] During use, the design of the cross bar 28 can enable the slider 26 to slide stably in the slide groove 25 without shaking, thereby maintaining the stable sliding of the slider 26.

[0044] In some embodiments, the clamping assembly 2 further includes: a placement plate 29 disposed on one side of the bottom end of the clamping plate 27 .

[0045] When in use, the placement plate 29 can support the window frame when it is placed.

[0046] In some embodiments, a clamping assembly 3 is provided on the clamping plate 27, and the clamping assembly 3 includes: a convex plate 31 provided on one side of the top end of the clamping plate 27; the bottom end of the threaded rod 32 passes through the convex plate 31 and is threadedly connected to the convex plate 31; a bottom plate 33 is rotatably provided at the bottom of the threaded rod 32; a through groove 34 is opened on the outer wall of the clamping plate 27; one end of the pressure block 35 passes through the through groove 34 and is connected to the bottom plate 33.

[0047] During use, in order to prevent the window frame from shaking during the milling process, the threaded rod 32 can be rotated so that the threaded rod 32 moves downward through the convex plate 31 and pushes the bottom plate 33 to move downward. The bottom plate 33 drives the pressing block 35 to slide inside the through groove 34 to press the window frame and keep it stable.

[0048] In some embodiments, two through slots 34 and two pressing blocks 35 are symmetrically provided.

[0049] When in use, two symmetrical arrangements can provide a better pressing effect on the window frame, thereby making the fixation more secure.

[0050] In some embodiments, the pressing assembly 3 further includes: a knob 36 disposed on the top of the second threaded rod 32 .

[0051] The knob 36 is provided for easy gripping and rotation during use, and grooves are provided on the surface of the knob 36 to increase friction during rotation so that the knob 36 is not prone to slipping.

[0052] In the description of this specification, the reference terms "one embodiment", "some embodiments", "example", "specific example", "some examples", etc. mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification.

[0053] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.
