Description

Technical Field

[0001] This utility model relates to the field of roller accessories technology, and more specifically, to a roller structure for a machine tool protective canopy. Background Technology

[0002] Machine tool protective canopies are devices used to protect machine tool equipment. They can protect the machine tool's guide rails, lead screws, etc. from external corrosion and damage, and can strictly prevent dust, chips, hard sand particles, etc. from entering the rails, reduce damage to the sliding rail surface caused by hard particulate foreign objects, and reduce the impact of guide rail deformation due to operation on machining accuracy, thereby maintaining the machining accuracy of the machine tool.

[0003] Currently, machine tool protective canopies are usually slidably mounted on support beams. They are opened and closed by sliding and folding on the support beams to protect the machine tool. However, most existing protective canopies usually use sheet metal parts to slide on the support beams, which is not only costly to produce, but also has high friction and is not smooth enough, making the folding and opening of the protective canopy inconvenient. Therefore, this utility model proposes a roller structure for machine tool protective canopies. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a roller structure for machine tool protective canopy, which aims to solve the problem that most protective canopies in the prior art usually use sheet metal parts to slide on the support beam, which not only has high production costs, but also has large friction and is not smooth enough, resulting in inconvenient folding and opening of the protective canopy.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution:

[0008] A machine tool protective canopy roller structure includes a slider, an upper connecting plate and a side connecting plate fixedly connected to the slider, a rolling wheel rotatably connected inside the slider, a nut provided on one side end of the slider, and a screw movably inserted into one side end of the slider, with one end of the screw movably passing through the slider and the rolling wheel and threadedly connected to the nut.

[0009] As a preferred embodiment of this utility model, the inner circumference of the rolling wheel is fixedly connected to two bearings, and the screw passes through the two bearings.

[0010] As a preferred embodiment of this utility model, a gasket is fitted on the circumferential surface of the screw, and the gasket corresponds to the slider.

[0011] As a preferred embodiment of this utility model, the upper connecting plate is provided with an upper mounting hole, and the side connecting plate is provided with a side mounting hole.

[0012] As a preferred embodiment of this utility model, the slider, the upper connecting plate and the side connecting plate are all fixedly connected with reinforcing plates, and the slider, the upper connecting plate, the side connecting plate and the reinforcing plates are integrally injection molded.

[0013] 3. Beneficial effects

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) In this solution, the slider, upper connecting plate and side connecting plate are integrally injection molded, which has low cost and high strength. The upper connecting plate and side connecting plate fix the slider on the machine tool protective canopy profile. The slider is connected to a rolling wheel through the cooperation of a nut and a screw. The rolling wheel makes the slider slide on the support beam. When the machine tool protective canopy is folded and opened, the rolling wheel in the slider can reduce the friction at the connection with the support beam, so that the folding and opening is smoother and more stable.

[0027] Example:

[0028] Please see Figure 1-6 A machine tool protective canopy roller structure includes a slider 1, an upper connecting plate 2 and a side connecting plate 3 fixedly connected to the slider 1, a rolling wheel 4 rotatably connected inside the slider 1, a nut 5 provided on one side end of the slider 1, and a screw 6 movably inserted into one side end of the slider 1, with one end of the screw 6 movably passing through the slider 1 and the rolling wheel 4 and threadedly connected to the nut 5.

[0029] In this embodiment, the screw 6 passes through the slider 1 and the rolling wheel 4 and is threadedly connected to the nut 5, so that the rolling wheel 4 is stably rotated and connected to the inner side of the slider 1. The upper connecting plate 2 is fixedly installed on the top of the machine tool protective canopy profile, and the side connecting plate 3 is fixedly installed on one end of the machine tool protective canopy profile. The upper connecting plate 2 and the side connecting plate 3 make the slider 1 stably fixed on the machine tool protective canopy profile. The slider 1 is fastened to the support beam, so that the rolling wheel 4 contacts the support beam. The machine tool protective canopy can slide stably on the support beam through the rolling wheel 4 inside the slider 1, realizing the folding switch.

[0030] Specifically, two bearings 7 are fixedly connected to the inner circumference of the rolling wheel 4, and the screw 6 passes through the two bearings 7.

[0031] In this embodiment, the rolling wheel 4 is rotatably connected to the screw 6 through two bearings 7, and can rotate stably inside the slider 1, so that the machine tool protective canopy can move smoothly on the support beam.

[0032] Specifically, a washer 8 is fitted on the circumferential surface of the screw 6, and the washer 8 corresponds to the slider 1.

[0033] In this embodiment, the screw 6 is threadedly connected to the nut 5 to lock the rolling wheel 4 inside the slider 1. The washer 8 is placed between the screw head of the screw 6 and one side end of the slider 1, which can prevent the excessive pressure of the screw 6 from damaging the slider 1, and at the same time prevent the screw 6 from loosening and affecting the stability of the rolling wheel 4.

[0034] Specifically, the upper connecting plate 2 has an upper mounting hole 9, and the side connecting plate 3 has a side mounting hole 10.

[0035] In this embodiment, the upper connecting plate 2 is fixedly installed on the top of the machine tool protective canopy profile through the upper mounting hole 9 and bolts, and the side connecting plate 3 is fixedly installed on one end of the machine tool protective canopy profile through the side mounting hole 10 and bolts.

[0036] Specifically, reinforcing plates 11 are fixedly connected to slider 1, upper connecting plate 2, and side connecting plate 3, and slider 1, upper connecting plate 2, side connecting plate 3, and reinforcing plates 11 are integrally injection molded.

[0037] In this embodiment, the slider 1, the upper connecting plate 2 and the side connecting plate 3 are integrally injection molded with high strength. The reinforcing plate 11 can further improve the strength of the slider 1, the upper connecting plate 2 and the side connecting plate 3, and ensure the stability of the machine tool protective shed when it moves.

[0038] Working principle: The slider 1 is installed on the machine tool protective canopy profile through the upper connecting plate 2 and the side connecting plate 3, and is slidably connected to the support beam through the rolling wheel 4. When the machine tool protective canopy is folded and opened, the protective canopy moves on the support beam through the rolling wheel 4 in the slider 1. The rolling wheel 4 reduces the friction between the machine tool protective canopy and the support beam, making the folding and opening of the machine tool protective canopy smoother.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
