Description

Technical Field

[0001] This utility model relates to the field of machining equipment, and in particular to a large belt sander. Background Technology

[0002] A belt sander is an industrial device that uses a high-speed rotating belt to grind, polish, deburr, and finish the surface of workpieces. It is widely used in the processing of various materials such as metal, wood, and plastic, and features high efficiency, precision, and flexibility.

[0003] The existing technical solution has the following drawbacks: because the sanding belt is slidably installed on the top of the frame, the sliding distance is limited, which cannot fully utilize the worktable surface of the frame, and the grinding area is limited. Utility Model Content

[0004] The purpose of this invention is to provide a large belt sander to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A large belt sander includes a frame, a platform fixedly mounted on the top of the frame, a guide module fixedly mounted on the top of the frame, a slider slidably mounted on the guide module, and a grinding module fixedly mounted on the bottom of the slider.

[0007] The guiding module includes a first guide rail, a second guide rail, and an infrared ranging grating. Vertical support frames are provided on the top left and right sides of the frame. Multiple connecting beams are provided at equal intervals from front to back on the top of the support frames. The connecting beams are used to connect the top of the support frames on the left and right sides. The first guide rail is fixedly installed on the bottom left side of the beam, and the second guide rail is fixedly installed on the bottom right side of the beam. Sliding sliders are slidably installed on the bottom of both the first and second guide rails. The length direction of both the first and second guide rails is the front-back direction.

[0008] By adopting the above technical solution, because multiple crossbeams are set above the frame, a considerable length of the first and second guide rails can be fixed. With the first and second guide rails extending only slightly beyond the top of the frame, they will not deform much even when bearing the full weight of the grinding module, thus providing excellent load-bearing capacity. Compared to directly setting the extension of the guide rails on the frame, because there are no extra structures above the frame, more space can be provided for the first and second guide rails. This also means that the cross-sectional diameter of the first and second guide rails can be set to be larger, resulting in stronger load-bearing capacity. Therefore, the first and second guide rails are set above the frame using a support frame and crossbeams.

[0009] In a further embodiment, the grinding module includes a belt sander, a housing, a first linear drive motor, and a second linear drive motor. The first linear drive motor is fixedly installed at the bottom of the slider of the first guide rail, and the second linear drive motor is fixedly installed at the bottom of the slider of the second guide rail. The housing is fixedly installed at the top of the belt sander, and the bottom of the housing is completely open. The bottoms of the first linear drive motor and the second linear drive motor are respectively fixedly connected to the left and right sides of the top of the housing. The first linear drive motor and the second linear drive motor are used to synchronously drive the housing to move up and down.

[0010] By adopting the above technical solution, when setting up, the bottom end face (outer surface of the sanding belt) of the belt sander needs to be located below the bottom of the housing. That is to say, the housing needs to expose the working part of the belt sander. The housing is controlled by the first linear drive motor and the second linear drive motor to carry the belt sander down, so as to achieve the effect of grinding the surface of the workpiece. It should be noted that the first guide rail and its bottom slider, as well as the second guide rail and its bottom slider, are all part of the linear motor. That is to say, the first guide rail and the second guide rail used in this application are motor-type guide rails that automatically control the sliding of the bottom slider.

[0011] In a further embodiment, sleeves are slidably mounted on the bottom ends of both the first and second guide rails, and two sleeves are provided on each of the first and second guide rails. The two sleeves are symmetrically arranged on the front and rear sides of the slider. One end of a support rod is fixedly mounted on the bottom of each sleeve, and the other end of the support rod is fixedly connected to the bottom end of the corresponding first linear drive motor / second linear drive motor body below.

[0012] By adopting the above technical solution, it should be noted that the first linear drive motor and the second linear drive motor are respectively composed of a moving part consisting of a body part and a sliding table, and the moving part is located at the bottom of one side of the body part (in order to adapt to the installation of the housing, the bottom of the moving part needs to be set to exceed the bottom of the body part). Because the length of the entire device will be relatively long after the telescopic part is extended, in order to reduce the shaking of the bottom of the body part of the first linear drive motor / second linear drive motor during the back and forth movement of the entire grinding module, a triangular support structure formed by the support rod is used to reduce the shaking. This is also why the first guide rail and the second guide rail need to be set above the entire frame to leave sufficient space to increase the structural strength of the grinding module.

[0013] In a further embodiment, limit baffles are fixedly installed at both ends of the first guide rail and the second guide rail.

[0014] By adopting the above technical solution, the limiting baffle is fixedly installed at both ends of the first guide rail and the second guide rail by bolts, which is used to limit the maximum position of the back-and-forth sliding of the entire grinding module.

[0015] In a further embodiment, an infrared rangefinder is fixedly installed on the inner bottom end of the housing.

[0016] By adopting the above technical solution, the main function of the infrared rangefinder is to measure the distance between the bottom of the outer shell and the top surface of the workpiece to be polished, and to slowly lower the polishing module after it has descended to a safe distance.

[0017] In a further embodiment, both ends of the first and second guide rails are covered with a buffer layer.

[0018] By adopting the above technical solution, since the first and second guide rails are raised, a buffer layer needs to be wrapped around the ends of the first and second guide rails to avoid accidental collisions between operators and the ends of the first and second guide rails.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. By setting multiple crossbeams above the frame, a considerable length of the first and second guide rails can be fixed. Since the extensions of the first and second guide rails beyond the top of the frame are minimal, they will not deform significantly even under the full weight of the grinding module, thus providing excellent load-bearing capacity. Compared to directly setting the guide rail extensions on the frame, the absence of extra structure above the frame allows for more space for the first and second guide rails. This also means that the cross-sectional diameters of the first and second guide rails can be set larger, resulting in stronger load-bearing capacity. Therefore, the use of a support frame and crossbeams to position the first and second guide rails above the frame is highly effective. Attached Figure Description

[0027] Example 1:

[0028] like Figures 1-3 As shown, a large belt sander includes a frame 1, a table 2 fixedly installed on the top of the frame 1, a guide module 3 fixedly installed on the top of the frame 1, a slider slidably installed on the guide module 3, and a grinding module 4 fixedly installed at the bottom of the slider.

[0029] The guide module 3 includes a first guide rail 31, a second guide rail 32, and an infrared ranging grating 33. Only one infrared ranging grating 33 needs to be set, which is set on the top of the first guide rail. The length direction of the infrared ranging grating 33 is consistent with the length direction of the first guide rail. When the slider at the bottom of the first guide rail is in different positions, it will block different areas of the infrared ranging grating 33. By identifying the blocked areas of the infrared ranging grating 33, the position of the slider can be known, thereby achieving precise control of the slider position.

[0030] like Figures 1-3As shown, vertically upward support frames are provided on the top left and right sides of the frame 1. Multiple connecting beams are evenly spaced from front to back on the top of the support frames, connecting the tops of the support frames on the left and right sides. A first guide rail 31 is fixedly installed on the bottom left side of the beam, and a second guide rail 32 is fixedly installed on the bottom right side of the beam. Slider blocks are slidably installed on the bottom of both the first and second guide rails 31 and 32. The length direction of both the first and second guide rails 31 and 32 is the front-to-back direction. The grinding module 4 includes a belt sander 41, a housing 42, a first linear drive motor 43, and a second linear drive motor 44. The first linear drive motor 43 is fixedly installed on the bottom of the slider of the first guide rail 31, and the second linear drive motor 44 is fixedly installed on the bottom of the slider of the second guide rail 32. The housing 42 is fixedly installed on the top of the belt sander 41, and the bottom of the housing 42 is completely open. The bottoms of the first linear drive motor 43 and the second linear drive motor 44 are fixedly connected to the top left and right sides of the outer shell 42, respectively. The first linear drive motor 43 and the second linear drive motor 44 are used to synchronously drive the outer shell 42 to move up and down. Sleeves are slidably installed at the bottom ends of the first guide rail 31 and the second guide rail 32. There are two sleeves on the first guide rail 31 and the second guide rail 32. The two sleeves are symmetrically arranged on the front and rear sides of the slider. One end of the support rod 5 is fixedly installed at the bottom of each sleeve. The other end of the support rod 5 is fixedly connected to the bottom end of the corresponding first linear drive motor 43 / second linear drive motor 44. Limiting baffles are fixedly installed at both ends of the first guide rail 31 and the second guide rail 32. An infrared rangefinder is fixedly installed at the inner bottom end of the outer shell 42. Both ends of the first guide rail 31 and the second guide rail 32 are covered with a buffer layer.

[0031] Specific implementation process: By setting multiple crossbeams located above the frame, a considerable length of the first and second guide rails can be fixed. With only a small extension of the first and second guide rails beyond the top of the frame, even when bearing the full weight of the grinding module, they will not deform much, thus providing excellent load-bearing capacity. Compared to directly setting the extension of the guide rails on the frame, because there is no extra structure above the frame, more space can be provided for the first and second guide rails. This also means that the cross-sectional diameter of the first and second guide rails can be set to be larger, resulting in stronger load-bearing capacity. Therefore, the effect of using a support frame and crossbeams to set the first and second guide rails above the frame is achieved.

[0032] In the embodiments disclosed in this utility model, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments disclosed in this utility model according to the specific circumstances.

[0033] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
