Description

Technical Field

[0001] The utility model belongs to the technical field of numerically controlled external cylindrical grinders, in particular to a numerically controlled external cylindrical grinder. Background Art

[0002] The CNC external cylindrical grinder is pre-programmed according to the processing requirements, and the control system sends out numerical information instructions for processing. It is mainly used for grinding cylindrical and conical outer surfaces. The CNC external cylindrical grinder has a movable dirt-blocking glass in front, through which the grinding condition can be observed.

[0003] Since the friction force of the conventional CNC external cylindrical grinder during the operation of the dirt shield glass is not much different from the friction force when it is stationary, when the friction force is too large, the pulling operation is difficult, and when the friction force is too small, the position stability after adjustment is relatively low, resulting in the problem of low practicality of the conventional CNC external cylindrical grinder.

[0004] To this end, we proposed a CNC cylindrical grinder to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problem of low practicability of conventional numerically controlled external cylindrical grinders and proposes a numerically controlled external cylindrical grinder.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

The transparent baffle is pulled forward to swing forward, and the transparent baffle is rolled along the guide rail to reduce resistance and determine the position, and then the transparent baffle is released to make the rear end of the transparent baffle contact with the guide rail, so that the friction between the transparent baffle and the guide rail is increased, so as to facilitate the movement or positioning of the transparent baffle.

[0008] Pull the elastic scraper to make it slide along the transparent baffle, use the elastic scraper to push the stains on the transparent baffle along both sides of the transparent baffle, push the stains to both sides of the transparent baffle, and facilitate cleaning the stains in the middle of the transparent baffle.

[0009] Preferably, the lower end of the bed is fixedly connected with supporting feet, and the supporting feet are symmetrically fixedly connected to the lower end of the bed, so that the bed can be stably placed on the ground.

[0010] Preferably, the guide rail comprises a first stop bar, a cylindrical sliding bar and a second stop bar, and the cylindrical sliding bar is fixedly connected between the first stop bar and the second stop bar.

The frame is pulled forward to swing forward around the sliding sleeve, so that the frame drives the leather strip to disengage from the first baffle rod, and the roller rolls along the second baffle rod, thereby reducing the moving resistance of the transparent baffle. The frame is released to swing backward, so that the leather strip is pressed on the first baffle rod, thereby reducing the moving resistance during convenient operation.

[0012] Preferably, the transparent baffle includes a handle, and the handle is fixedly connected to the front end of the frame, so that the transparent baffle can be conveniently operated by hand.

[0013] Preferably, the elastic scraper includes a connecting frame, a first spring sheet, a first scraping strip, a second spring sheet and a second scraping strip, wherein the first spring sheet and the second spring sheet are fixedly connected to the outer end of the connecting frame, the first scraping strip is fixedly connected to the first spring sheet, and the second scraping strip is fixedly connected to the second spring sheet. When the second spring sheet is pulled to move, the second spring sheet acts on the connecting frame, and the connecting frame acts on the first spring sheet, and the first scraping strip is driven to move synchronously by the first spring sheet, so that the first scraping strip and the second scraping strip slide along the glass, which is convenient for cleaning stains on the glass.

[0014] Preferably, the elastic scraper further comprises a pull button, and the pull button is fixedly connected to the outer end of the second elastic sheet, so that the elastic scraper can be conveniently operated by hand through the pull button.

[0015] In summary, the technical effects and advantages of the utility model are as follows:

[0016] 1. Pull the transparent baffle forward to swing it forward and roll it along the guide rail to reduce resistance. After determining the position, release the transparent baffle to make the rear end of the transparent baffle contact with the guide rail to increase the friction between the transparent baffle and the guide rail, making it easier to move or position the transparent baffle and improving practicality.

[0017] 2. Pull the elastic scraper to make it slide along the transparent baffle, and use the elastic scraper to push the stains on the transparent baffle along both sides of the transparent baffle, pushing the stains to both sides of the transparent baffle, so as to facilitate cleaning of the stains in the middle of the transparent baffle.

[0018] 3. Pull the frame forward and swing it forward around the sliding sleeve, so that the frame drives the leather strap to disengage from the first lever, and the roller rolls along the second lever to reduce the movement resistance of the transparent baffle. Loosen the frame and swing it backward to press the leather strap onto the first lever to reduce the movement resistance during operation.

[0019] 4. When the second spring piece is pulled to move, the second spring piece is used to act on the connecting frame, which acts on the first spring piece through the connecting frame, and the first scraper is driven to move synchronously through the first spring piece, so that the first scraper and the second scraper slide along the glass, which is convenient for cleaning stains on the glass.
