Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing protection, and particularly relates to a telescopic protective cover for a machine tool with a mortise and tenon welding process. Background Art

[0002] Protective covers are often installed on various machine tools to protect the key components of the machine tools. During use, the chips generated during the production process of the machine tool will fall on the protective cover. At present, there are mainly two structures of the protective cover. One is an armored protective cover, which is formed by laying armor on the top of a traditional bellows protective cover. It can only cover the top of the bellows protective cover and cannot prevent iron chips from falling into the folding part of the bellows protective cover, which is likely to cause damage to the bellows protective cover. The other is a telescopic protective cover formed by integrally bending and laminating steel plates. After bending the steel plates, end plates are welded at the ends to keep the steel plates in the bent shape, ensuring good cooperation between adjacent steel plates and smooth relative movement. The protective cover with this structure has a longer service life. However, since the steel plates still have a certain amount of resilience after bending, they are prone to deformation during welding, resulting in a reduction in the final forming accuracy of the steel plates and easy generation of noise during the movement of the telescopic protective cover. Content of the Utility Model

[0003] Aiming at the deficiencies of the above-mentioned prior art, the technical problem to be solved by the utility model is: how to provide a telescopic protective cover for a machine tool with a mortise and tenon welding process, which has a reasonable structural design, can ensure the welding accuracy and forming accuracy, and is beneficial to improving the quality of the protective cover.

[0004] In order to solve the above technical problems, the utility model adopts the following technical scheme:

[0005] A telescopic protective cover for a machine tool with a mortise and tenon welding process, characterized in that it includes a support frame and a telescopic protective cover. The telescopic protective cover includes a plurality of protective plates that are sequentially stacked and connected. Adjacent two of the protective plates can slide relatively horizontally, and a connecting member for keeping adjacent two of the protective plates in a stacked and connected state is also provided therebetween; in the telescopic direction of the telescopic protective cover, one end of the protective plate is fixedly connected with an end plate with a matching shape. The protective plate has tenons protruding towards the end plate. The height of the tenons is less than or equal to the thickness of the end plate, and a plurality of them are arranged at intervals along the side edge of the protective plate; the end plate has mortise holes corresponding to the tenons. The tenons of the protective plate are inserted into the mortise holes of the end plate in a matching manner, and the protective plate is welded to the end plate.

[0006] In the above structure, due to the structure of the tenon and mortise joint between the protective plate and the end plate, the formed shape of the protective plate can be determined by the end plate before welding. This can not only reduce the deformation of the protective plate during welding, but also reduce the welding difficulty and enhance the strength of the protective plate. During welding, the tenon position can be used as a reference to set the welding points at the designed positions, avoiding interference after assembly caused by the displacement of the welding points, which is beneficial to improving the quality. The forming quality of the protective plate is reliable, making the telescopic protective plate move more smoothly.

[0007] Further, the support frame includes a first support frame and a second support frame that are parallel and facing each other, and both ends in the telescopic direction of the telescopic protective cover are respectively connected to the first support frame and the second support frame.

[0011] In this way, the upper baffle plate located below is slidably buckled in the sliding groove of the upper baffle plate located above. The protective plate located in the lower layer can support the protective plate in the upper layer, and the force on the protective plate is more uniform. Under the action of the guiding groove, the telescopic protective cover is not prone to deflection during movement, and it also prevents the protective plate from falling off in other directions, having a limiting effect.

[0012] Further, a slider is provided between adjacent upper baffle plates, and the slider is located inside the sliding groove; a positioning hole running through from the outside to the inside is provided on the side wall of the sliding groove, and the slider has a threaded hole corresponding to the positioning hole and is fixed inside the sliding groove by a bolt passing through the positioning hole.

[0014] In this way, during the extension and retraction process of the telescopic protective cover, all the protective plates move synchronously under the action of the connecting parts.

[0015] Furthermore, the hinge support includes a U-shaped base, the base has a connecting plate extending toward the end plate, and the connecting plate is fixedly mounted on the end plate; a clearance space for other protective plates to extend into is formed between the base and the connecting plate and the corresponding protective plate.

[0016] Furthermore, the lower end of the end plate is provided with a slide groove for supporting the sliding of the protective plate, and the slide groove is distributed and arranged directly below the upper baffle plate and the lower baffle plate; the slide groove includes a horizontally arranged supporting edge and a vertically arranged limiting edge, and the spacing between the limiting edges of the two slide grooves matches the width of the protective cover guide rail of the machine tool to be protected.

[0017] Furthermore, an overall L-shaped sliding seat is provided on the slide groove, and the sliding seat includes a first side plate and a second side plate arranged opposite to each other on both sides of the end plate, and a connecting part arranged along the supporting edge and the limiting edge of the slide groove is connected between the first side plate and the second side plate.

[0018] Furthermore, the first side plate and the second side plate are integrally formed, and a mounting groove penetrating along the thickness direction is provided on the connecting portion of the slide seat, and a roller is rotatably provided in the mounting groove, and the roller is provided along the supporting edge of the slide groove.

In this way, during the telescopic protective cover telescopic process, all protective plates move synchronously under the action of the connecting member.

[0031] Specifically, the hinge support includes a U-shaped base, the base has a connecting plate extending toward the end plate 21, and the connecting plate is fixedly mounted on the end plate 21; a clearance space for other protective plates to extend into is formed between the base and the connecting plate and the corresponding protective plate, such as Figure 5 and Figure 6 shown.
