Description

Technical Field

[0001] The utility model belongs to the technical field of grinding devices, and particularly relates to a surface grinding device for sheet metal parts. Background Art

[0002] Mechanical equipment and even household appliances often need to isolate the internal devices from the outside through a housing. On the one hand, it protects the user to form a safety isolation, and on the other hand, it provides a complete and beautiful appearance through the housing to improve the product competitiveness. Currently, for plastic housings, injection molding and other methods are often used. However, for larger housings with higher strength requirements, metal sheet metal parts are often used. Metal sheet metal parts are often formed by stamping, bending, and welding positioning. It is inevitable to cause scratches on the surface of the sheet during bending or welding, and the welding is uneven. This requires grinding to smooth the sheet metal parts. Summary of the Invention

[0004] To solve the above technical problems, the purpose of the utility model is realized as follows:

[0005] A surface grinding device for sheet metal parts includes a frame, a working platform, a grinding component, a horizontal reciprocating motion component, and a vertical reciprocating motion component. The working platform is movably arranged on the frame. The vertical reciprocating motion component drives the working platform to translate vertically, and the working platform can slide horizontally longitudinally under the drive of an external force. The grinding component is movably arranged on the frame and is located above the working platform. The horizontal reciprocating motion component drives the grinding component to reciprocate horizontally.

[0006] On the basis of the above solution and as a preferred solution of the above solution: The working platform is arranged on a slide rail, and the slide rail is fixedly connected to the output end of the vertical reciprocating motion component through a bracket.

[0007] On the basis of the above solution and as a preferred solution of the above solution: The vertical reciprocating motion components are symmetrically arranged on both sides of the working platform.

[0008] On the basis of the above solution and as a preferred solution of the above solution: It further includes a driving motor and a driving shaft. The vertical reciprocating motion component includes a chain drive component. The bracket is fixedly arranged on one side of the chain of the chain drive component. It further includes a counterweight block, and the counterweight block is fixedly arranged on the other side of the chain. The driving shaft synchronously drives the two chain drive components.

[0009] On the basis of the above solution and as a preferred solution of the above solution: It further includes a vertical guide rod, and both the bracket and the counterweight are slidably connected to the vertical guide rod.

[0010] On the basis of the above solution and as a preferred solution of the above solution: The frame includes a horizontal transverse slide rail, and the grinding assembly is slidably arranged on the horizontal transverse slide rail.

[0011] On the basis of the above solution and as a preferred solution of the above solution: The grinding assembly includes a grinding drive assembly, a grinding head, and a grinding vertical adjustment assembly. The grinding drive assembly drives the grinding head to rotate, and the grinding vertical adjustment assembly drives the grinding drive assembly and the grinding head to move vertically.

[0012] The prominent and beneficial technical effects of the present utility model compared with the prior art are as follows: Through the grinding assembly and the movable work platform, the sheet metal parts placed on the work platform can be ground and polished; the work platform can be vertically translated to adapt to sheet metal parts of different thicknesses and heights for grinding.

[0018] To make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the given embodiments, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.

[0019] In the description of the present application, it should be understood that the orientation or positional relationship indicated by terms such as "upper" and "lower" is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present application.

[0020] In the description of the present application, terms such as "first" and "second" are only used for descriptive purposes, and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features.

[0021] See Figures 1-5 As shown, a surface grinding device for a sheet metal part of the present application includes a frame 10, a working platform 50, a grinding assembly 30, a horizontal reciprocating motion assembly 20, and a vertical reciprocating motion assembly 40; specifically, in this embodiment, the working platform 50 is movably arranged on the frame 10, the vertical reciprocating motion assembly 40 drives the working platform 50 to translate vertically, and the working platform 50 can slide horizontally longitudinally under the drive of an external force; the working platform 50 is arranged on a slide rail 52, and the slide rail 52 is fixedly connected to the output end of the vertical reciprocating motion assembly 40 through a bracket 53.

[0022] The grinding assembly 30 is movably arranged on the frame 10 and is located above the working platform 50. The horizontal reciprocating motion assembly 20 drives the grinding assembly 30 to horizontally reciprocate. Specifically, the frame 10 includes a horizontal transverse slide rail 11, and the grinding assembly 30 is slidably arranged on the horizontal transverse slide rail 11. The grinding assembly 30 includes a slide plate 31, a grinding drive assembly 32, a grinding head 34 and a grinding vertical adjustment assembly 33. The slide plate 31 has a vertical plate 311. The vertical adjustment assembly 33 includes an adjustment vertical plate 331, a lead screw nut 332 and an adjustment lead screw 333. Of course, a vertical slide rail is arranged between the adjustment vertical plate 331 and the vertical plate 311. The lead screw nut 332 is fixedly installed on the adjustment vertical plate 331. The adjustment lead screw 333 is vertically installed and connected to the lead screw nut. Of course, a positioning member is arranged at the upper end of the adjustment lead screw 333 so that while the adjustment lead screw 333 can rotate flexibly, its axial movement is restricted (it can be restricted by setting bearings and shaft section retaining rings, which is the same as the prior art and will not be elaborated here). Then, when the adjustment lead screw 333 is rotated, the adjustment vertical plate 331 will be driven to move vertically. The grinding drive assembly 32 is fixedly installed on the adjustment vertical plate 331 of the vertical adjustment assembly 33. The grinding head 34 includes a support wheel and a grinding sandpaper, and the grinding sandpaper is sleeved on the support wheel (this is the prior art and will not be elaborated here). The grinding drive assembly 32 drives the grinding head 34 to rotate, and the grinding vertical adjustment assembly 33 drives the grinding drive assembly 32 and the grinding head 34 to move vertically, realizing fine adjustment of the surface distance between the grinding head 34 and the sheet metal part. The horizontal reciprocating motion assembly 20 includes a servo motor 21, a first synchronous belt drive assembly and a second synchronous belt drive assembly. Among them, the second synchronous belt drive assembly includes two symmetrically arranged synchronous belt pulleys 22 and a synchronous belt 23 wound around the synchronous belt pulleys 22. The slide plate 31 is fixedly connected to the synchronous belt 23 through a connecting member. The connecting member can be two clamping blocks. One end of the clamping block is connected to the slide plate 31, and the other end extends towards the synchronous belt 23. The other clamping block is screwed to the upper clamping block from below by a bolt to clamp the synchronous belt. Thus, the synchronous belt 23 can drive the slide plate 31 to slide along the horizontal transverse slide rail 11.

[0023] The vertical reciprocating motion assembly 40 is symmetrically arranged on both sides of the working platform 50. Specifically, it further includes a driving motor 41 and a driving shaft 412. The driving motor 41 is fixedly arranged on the frame located below the working platform, and drives the driving shaft 412 to rotate through a transmission sprocket set 411. The vertical reciprocating motion assembly 40 includes a chain drive assembly 42. The chain drive assembly 42 includes a first sprocket 421, a chain 422 and a second sprocket 423. The first sprocket 421 is fixedly arranged at one end of the driving shaft 412, and the second sprocket 423 is movably arranged on the frame. The bracket 53 is fixedly arranged on one side of the chain 422 of the chain drive assembly 42. It can also be connected by pressing the chain with a pressing plate or other structures of the existing technology. Considering that the weight of the working platform 50 is relatively large, it will increase the load of the vertical reciprocating motion assembly, and the impact force is also relatively large, which is easy to generate relatively large vibration, and at the same time increases the power requirement for the driving motor 41. Therefore, this embodiment further includes a counterweight 43, and the counterweight assembly 43 is fixedly arranged on the other side of the chain 422. The driving shaft 412 synchronously transmits power to the two chain drive assemblies 42. Through the setting of the counterweight, it is balanced with the weight of the working platform, and the load and impact of the vertical reciprocating motion assembly during operation are well reduced.

[0024] Certainly, in order to make the movement of the working platform and the counterweight more stable, this embodiment further preferably includes a vertical guide rod 12. Both the bracket 53 and the counterweight 43 are slidably connected to the vertical guide rod 12. Thereby, the smoothness of its operation is ensured.

[0025] Thus, through the grinding assembly and the movably arranged working platform, the sheet metal parts placed on the working platform can be ground and polished. The working platform can be vertically translated to adapt to sheet metal parts of different thicknesses and heights for grinding. At the same time, the working platform can move horizontally and longitudinally. The worker can manually push the working platform inward to meet the grinding of sheet metal parts with different structures. The grinding assembly can realize vertical height adjustment, and then finely adjust the grinding amount, which is more conducive to improving the grinding quality.

[0026] The above embodiments are only the preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present invention should be covered within the protection scope of the present invention.
