Description

Technical Field

[0001] The utility model belongs to the technical field of machine tools, in particular to a steel telescopic protective cover for a machine tool guide rail. Background Art

[0002] Machine tool guide rails are important parts on machine tools. In order to prevent pollution and improve workplace safety, it is necessary to install protective covers on the machine tool guide rails to surround and protect them.

[0003] Among them, after searching, it was found that there is a patent number CN202220638668.9, which discloses a machine tool guide rail protective cover, including a protective shell, an external slide rail and a sliding sealing device. The protective shell is an inverted U-shaped structure. The protective shell is provided with several sliding connections. It has a sliding sealing device. When the protective shells are in a sliding state, the elastic sealing strip of the sliding sealing device will abut against the bottom surface of the adjacent protective shell top plate and seal, which can prevent external liquid or debris from entering the protective shell. When external coolant enters through the gap between the top of the protective shell, the winding elastic sealing strip will prevent the liquid from entering. At the same time, the coolant falls into the drainage groove of the receiving plate through the right end of the protective shell, and flows forward and backward along the drainage groove. The coolant flows down the ends and finally flows down to the machine tool along the front and rear side vertical plates of the protective shell. The device provides double insurance through the dual settings of sealing strips and elastic sealing strips to prevent liquid from entering the analysis. Even if the coolant enters from the gap, due to the settings of the receiving plate and the drain trough, it will be caught by the drain trough and discharged to the front and rear ends and flow down along the vertical plates of the protective shell without dripping onto the guide rails to prevent the guide rails from rusting. In addition, the device is provided with an external slide rail, and the protective shells are slidably connected to the external slide rails by connecting rods. In this way, it can be ensured that all protective shells slide in a straight line under the action of the external slide rails without skewing, thereby preventing the problem of reduced opening sealing due to skewing of the protective shells at a certain angle, thereby enhancing the sealing.

[0004] However, after research, it was found that: the protective cover is not easy to adjust the maximum telescopic length, cannot meet the needs of machine tool guide rails of different lengths, is not flexible enough to use, the protective cover is not convenient to disassemble, and is not convenient for recycling the protective cover on the discarded machine tool guide rails. There is no structure to reduce the friction of the protective cover when it moves. Therefore, a new device is provided to solve this problem. Utility Model Content

[0005] The utility model aims to provide a steel telescopic protective cover for a machine tool guide rail in order to solve the problem that the use is not flexible and convenient enough.

[0006] The technical solution adopted by the utility model is as follows: a steel telescopic protective cover for a machine tool guide rail, comprising a machine tool guide rail, the machine tool guide rail is equipped with a slider, and the machine tool guide rail has a protective cover A and a protective cover B on the outside;

[0007] The protective cover A and the protective cover B are both provided with adjustment mechanisms for adjusting the maximum length of the telescopic protective cover.

[0008] Among them, the adjustment mechanism includes a slide rail, a limit block, a spring sheet and a connecting rod. The slide rail is embedded in the upper middle part of the protective cover A and the upper middle part of the protective cover B, and a slider that fits the slide rail is fixedly installed on one side above the protective cover B. The limit block is movably connected to the entrance of the slide rail, and the limit block is symmetrically and elastically connected with spring sheets on both sides, and the inside of the slide rail is symmetrically embedded with grooves that fit with the spring sheets on both sides. The two sides of the protective cover A and the two sides of the protective cover B are symmetrically embedded with connecting rods through through grooves, and the ends of the connecting rods extend into the inside of the grooves. The protective cover A and the protective cover B are both C-shaped, and the inner walls of the protective cover A and the inner walls of the protective cover B are bonded with sealing rubber pads.

[0009] Among them, a fixing clamp A is fixedly installed on the middle part of the upper part of the protective cover A, and the fixing clamp A is set in a U shape. A clamp plate A is slidably connected to the inside of the fixing clamp A through a slide rail. A fastening bolt A is embedded in one side of the fixing clamp A and is rotatably connected to the clamp plate A. Fixing clamps B are symmetrically fixedly installed on both sides of the protective cover A, and the fixing clamp B is set in an L shape. A clamp plate B is slidably connected to the inside of the fixing clamp B through a slide rail. A fastening bolt B is embedded in one side of the fixing clamp B and is rotatably connected to the end of the fastening bolt B. A connecting plate is provided on the outside of the machine tool guide rail, and the connecting plate is set in a C shape. The size of the connecting plate matches the protective cover B. The protective cover B is fixed to the connecting plate by fixing bolts. The connecting plate is bonded to both sides of the slider by strong glue. Ball bearings are equidistantly and symmetrically rotatably connected to the two sides of the bottom of the protective cover B. Rubber sealing strips are bonded to the center of the bottom of both sides of the protective cover B.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0011] 1. In the utility model, through the adjustment mechanism, according to the length of the machine tool guide rail, multiple protective covers B that fit each other and one protective cover A are sequentially sleeved together to form a steel telescopic protective cover, so that the maximum length of the protective cover A and multiple protective covers B pulled out is consistent with the longest path of the slider moving on the machine tool guide rail, which can meet the needs of machine tool guide rails of different lengths and is more flexible to use.

[0012] 2. In the utility model, the fixing bolts between the protective cover B and the connecting plate are removed, and the fastening bolts A and the fastening bolts B are screwed to remove the two telescopic protective covers from the machine tool guide rails. Then, by pressing the connecting rod, the connecting rod pushes the spring piece out of the slot, and the limit block is removed from the inside of the slide rail. Then, the corresponding protective cover B is removed, and the length of the telescopic protective cover is adjusted and installed above other machine tool guide rails, so that the telescopic protective cover on the abandoned machine tool guide rails can be disassembled and recycled, which is more convenient to use.

[0013] 3. In the utility model, the ball bearing reduces the friction force generated during the movement of the protective cover B, making the protective cover B move more smoothly. The rubber sealing strip ensures the sealing between the bottom of the protective cover B and the base of the machine tool guide rail, thereby ensuring the sealing of the telescopic protective cover.
