[0002] A food truck is a mobile kitchen that sells breakfast on the street or at intersections. With the ever-increasing pace of life, people often need to buy breakfast outside. The advent of food trucks has effectively solved the problem of office workers being short on time and having no time to prepare breakfast, while also significantly improving the convenience of residents' lives. During the production of food truck windows, the window workpieces need to be milled. Milling is a machining method that uses a milling cutter as a tool to process the surface of an object. During milling, the part to be milled is first fixed, and then the milling cutter is moved across the part with high-speed rotation. During milling, the part to be milled often needs to be fixed on a workbench.

[0003] Chinese utility model CN214922458U uses an automatic positioning tool for a milling machining center, and designs a clamping structure. The principle is that the motor drives the threaded rod to rotate, and when the threaded rod rotates, it drives the slider to move closer, and at the same time, the clamping plate moves closer to clamp and fix the workpiece, and then the milling device is used to perform milling on it.

[0004] However, the slider of the existing device slides inside a chute located on top of the workbench. During milling, a lot of metal debris falls into the chute and accumulates on the surface of the threaded rod, increasing friction on the threaded rod, making it difficult to rotate and thus affecting clamping. Therefore, to address this problem, a milling positioning tool that is not easily affected by debris was designed. Utility Model Content

[0031] A food truck is a mobile kitchen that sells breakfast on the street or at intersections. With the ever-increasing pace of life, people often need to buy breakfast outside. The advent of food trucks has effectively solved the problem of office workers being short on time and having no time to prepare breakfast, while also significantly improving the convenience of residents' lives. During the production of food truck windows, the window workpieces need to be milled. Milling is a machining method that uses a milling cutter as a tool to process the surface of an object. During milling, the part to be milled is first fixed, and then the milling cutter is moved across the part with high-speed rotation. During milling, the part to be milled often needs to be fixed on a workbench.

[0032] In the related art, a motor drives a threaded rod to rotate, which in turn drives a slider to move closer, and simultaneously brings the clamping plate closer to clamp and fix the workpiece, which is then milled using a milling device. However, the slider of the existing device slides inside a chute, which is located on the top of the workbench. During milling, a lot of metal debris falls into the chute and accumulates on the surface of the threaded rod, increasing friction on the threaded rod, making it difficult to rotate, thereby affecting clamping and fixation.

[0033] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a car window milling and positioning tool. When it is necessary to mill a dining car window workpiece, the dining car window workpiece is first held by hand, and then the threaded rod 28 is rotated. As the threaded rod 28 rotates, the threaded block 29 is driven to move. During the movement of the threaded block 29, the connecting rod 27 is pulled to rotate, so that one end of the connecting rod 27 slides inside the slide groove 26, so that the two sliders 23 move closer on the cross bar 25. At the same time, the sliders 23 push the clamping plate 24 closer to clamp the car window workpiece. Finally, the workpiece is milled using the milling machine 12. When the workpiece size is different, it is necessary to adjust the height of the housing 22 so that the clamping plate 24 is easier to clamp with the workpiece. It is only necessary to pull out the insertion rod 33. At this time, the two ends of the housing 22 slide up and down on the inner side of the vertical plate 21. After adjusting to the appropriate position, the positioning hole 32 is aligned with the adjustment hole 31, and the insertion rod 33 is inserted to limit the height of the housing 22. The height adjustment of the housing 22 can be completed.

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

[0035] Combine Figures 1-4 The embodiment of the present application provides a car window milling and positioning tool, including: a workbench 11 with a milling machine 12 on the top thereof, for milling the car window workpiece; a clamping assembly 2 is provided on the workbench 11, and the clamping assembly 2 includes: a vertical plate 21 arranged on the top of the workbench 11; two ends of a shell 22 are connected to the inner side of the vertical plate 21; a slider 23 is arranged inside the shell 22; a clamping plate 24 is arranged on one side of the slider 23; two ends of a cross bar 25 pass through the slider 23 and are connected to the inner side wall of the shell 22; a slide groove 26 is opened on the outer side wall of the shell 22; one end of a connecting rod 27 is inserted into the slide groove 26 and is rotatably connected to the slider 23; a threaded rod 28 is rotatably arranged on the outer side wall of the shell 22; a threaded block 29 is sleeved on the outer side wall of the threaded rod 28, and is threadedly connected to the threaded rod 28, and its two sides are rotatably connected to the other end of the connecting rod 27.

[0036] Specifically, the milling machine 12 is model XK5040, and its working principle mainly relies on the rotation of the milling cutter and the movement of the workpiece or the milling cutter to achieve the processing of the workpiece. Milling is a mechanical processing method that uses a rotating multi-edge tool to cut the workpiece and is a highly efficient processing method. During the milling process, the milling cutter rotates as the main motion, while the movement of the workpiece or the milling cutter acts as the feed motion, together completing the processing of the workpiece. Milling can process a variety of workpiece surfaces, such as flat parts and curved parts, including but not limited to planes, grooves, curved surfaces, gears, etc.

[0037] When the dining car window workpiece needs to be milled during use, the dining car window workpiece is first held by hand, and then the threaded rod 28 is rotated. As the threaded rod 28 rotates, the threaded block 29 is driven to move. During the movement of the threaded block 29, the connecting rod 27 is pulled to rotate, so that one end of the connecting rod 27 slides inside the slide groove 26, so that the two sliders 23 move closer on the cross bar 25. At the same time, the sliders 23 push the clamping plate 24 closer to clamp the window workpiece, and finally the workpiece is milled using the milling machine 12. The debris generated during the milling process will not accumulate inside the housing 22 or on the surface of the threaded rod 28, and will not affect the clamping effect of the clamping plate 24.

[0038] In some embodiments, the width of the sliding groove 26 is consistent with the width of the connecting rod 27 .

[0039] When in use, the width of the connecting rod 27 is consistent with the inner width of the sliding groove 26, so that the threaded block 29 is more stable and not easy to rotate with the threaded rod 28 when the threaded rod 28 rotates.

[0040] In some embodiments, the clamping assembly 2 further includes a rubber pad 241 disposed on one side of the clamping plate 24 .

[0041] During use, the design of the rubber pad 241 can prevent the surface of the workpiece from being scratched when in contact with the workpiece, thereby further protecting the workpiece.

[0042] In some embodiments, the clamping assembly 2 further includes a twist knob 281 disposed at one end of the threaded rod 28 .

[0043] The setting of the knob 281 is convenient for gripping during use, and the grooves on the surface of the knob 281 can increase the friction force when rotating, so that it is not easy to slip during rotation.

[0044] In some embodiments, the shell 22 is slidably connected to the vertical plate 21, and a sliding component 3 is provided on the vertical plate 21, and the sliding component 3 includes: an adjustment hole 31 opened on the outer wall of the vertical plate 21; positioning holes 32 opened at both ends of the shell 22; one end of the insertion rod 33 passes through the adjustment hole 31 and is inserted into the interior of the positioning hole 32.

[0045] When in use, if the workpiece is of different sizes, it is necessary to adjust the height of the shell 22 so that the clamping plate 24 can be easily clamped with the workpiece. You only need to pull out the insertion rod 33. At this time, the two ends of the shell 22 slide up and down on the inner side of the vertical plate 21. After adjusting to the appropriate position, align the positioning hole 32 with the adjustment hole 31, and insert the insertion rod 33 to limit the height of the shell 22. The height adjustment of the shell 22 can be completed.

[0046] In some embodiments, the sliding assembly 3 further includes: balls 34 disposed at both ends of the housing 22 .

[0047] During use, the provision of the balls 34 can reduce the friction between the two ends of the shell 22 and the inner side of the vertical plate 21, making the shell 22 smoother when sliding up and down.

[0048] In some embodiments, the clamping assembly 2 further includes: a cone 35 disposed at one end of the insertion rod 33 .

[0049] The pointed design of one end of the cone 35 makes it easier to insert when it cannot be inserted into the positioning hole 32 and the adjustment hole 31 during use.

[0050] In some embodiments, the sliding assembly 3 further includes: a spring wire 36 disposed on the top of the workbench 11 , and the top end of the spring wire is connected to the insertion rod 33 .

[0051] The provision of the spring line 36 during use can prevent the insertion rod 33 from being lost, and prevent the insertion rod 33 from being lost when needed.

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.
