Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a sealing structure for a worktable guide rail and a lead screw. Background Technology

[0002] In cutting machines, drilling machines, and other similar machines, the workpiece is placed on a worktable during operation. The worktable moves back and forth along guide rails driven by a lead screw, thus feeding the workpiece. Typically, guide rails are installed on both sides of the bottom surface of the worktable, with a lead screw in the middle. However, both linear guide rails and ball screws are high-precision components, and they are prone to rusting or clogging after contact with water or other cutting fluids (such as mortar), affecting working accuracy and lifespan.

[0003] To solve the above problems, various sealing devices have been developed. For example, Chinese patent application [Authorization Announcement No.: CN204054367U] discloses a waterproof device for a glass drilling machine's moving guide rail and ball screw, including a slide, a water-blocking cover, a moving guide rail assembly, and a ball screw. The slide is a groove-shaped body with an upward-curving center on its bottom surface, forming a strip-shaped groove. A gap is left between the top and bottom surfaces of the slide, which serves as the installation space for the water-blocking cover. The moving guide rail assembly is set in the strip-shaped groove at the bottom of the slide, and the ball screw is set between the moving guide rail assemblies. The water-blocking cover is set in the gap between the top and bottom surfaces of the slide and extends forward and backward to cover the ball screw, preventing water from entering the moving guide rail assembly and the ball screw.

[0004] Although the above structure can be waterproofed with a water shield, in actual use, a larger slide is required to move some larger workpieces. The groove at the bottom of the slide spans two guide rails, and to increase rigidity, it needs to be made larger. At the same time, a larger slide motor is required to drive it, which results in energy waste. In addition, the larger water shield has poor rigidity and is not convenient for installation and maintenance. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a sealing structure for the worktable guide rail and lead screw. The technical problem to be solved by this utility model is: how to solve the problem of poor sealing between the guide rail and lead screw when the existing worktable is large.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A sealing structure for a workbench guide rail and a ball screw, the workbench including a base and at least two guide rails disposed on the base, a ball screw rotatably connected between two adjacent guide rails, a slider slidably connected to the guide rails, and a nut threadedly connected to the ball screw, characterized in that the sealing structure includes a slide table disposed above the ball screw and guide rails, a connecting plate and a mounting plate corresponding to each slider fixedly connected below the slide table, the connecting plate being fixedly connected to the nut, the mounting plate being fixedly connected to the corresponding slider, and a waterproof cover one and a waterproof cover two connected to the base, the waterproof cover one covering the ball screw and located between the slide table and the connecting plate, and the waterproof cover two covering the guide rails and located between the sliders and the corresponding mounting plates.

[0008] At least two guide rails are provided on the base, and a ball screw is rotatably connected between two adjacent guide rails. A slider is slidably connected to the guide rail, and a nut is threaded onto the ball screw. A slide is positioned above the ball screw and guide rails. A connecting plate and a mounting plate are fixedly connected below the slide. The connecting plate is fixedly connected to the nut. Waterproof cover one and waterproof cover two are connected to the base. Waterproof cover one is located between the connecting plate and the slide and covers the ball screw. The mounting plate is fixedly connected to the corresponding slider. Waterproof cover two is located between the mounting plate and the slide and covers the guide rail. By separately providing waterproof cover one and waterproof cover two, a split design is adopted. Compared with the integrated design of waterproof cover one and waterproof cover two, it is easier to install and maintain, reduces the driving force of the motor to move the slide, and makes the rotation of the ball screw less strenuous. Furthermore, waterproof cover one and waterproof cover two are connected to the base and do not contact the slide during sliding. Waterproof cover one and waterproof cover two are easy to install and do not affect the waterproof effect of the ball screw and guide rails.

[0009] In the sealing structure of the workbench guide rail and lead screw described above, both the first waterproof cover and the second waterproof cover have horizontally arranged waterproof plates. The left and right sides of the waterproof plates are folded down to form abutment plates, and the abutment plates on both sides of the waterproof plates are inclined away from each other from top to bottom.

[0010] By incorporating a backing plate, water adhering to the backing plate can be easily diverted and quickly flow into the base, thus not affecting the movement of the guide rail and ball screw, thereby improving the drainage effect.

[0011] In the sealing structure of the workbench guide rail and lead screw described above, a pair of support plates 1 and multiple pairs of support plates 2 are fixedly connected to the base and are arranged in correspondence with the waterproof cover 2. The support plates 1 are respectively arranged at the front and rear ends of the waterproof cover 1, and the front and rear ends of the waterproof cover 1 abut against the corresponding support plates 1. Any pair of support plates 2 are arranged at the front and rear ends of the corresponding waterproof cover 2, and the front and rear ends of the waterproof cover 2 abut against the corresponding support plates 2.

[0012] This structure allows support plate one and support plate two to support the two ends of waterproof cover one and waterproof cover two respectively, preventing waterproof cover one and waterproof cover two from pressing on the connecting plate or mounting plate, thereby reducing the impact on the movement of the slide table and improving the stability of the installation of waterproof cover one and waterproof cover two.

[0013] In the sealing structure of the workbench guide rail and lead screw described above, the mounting plate includes a support portion that is horizontally arranged and connected to the upper end of the slider. The left and right sides of the support portion are both folded downward to form inclined portions. The two inclined portions are inclined away from each other from top to bottom. The support portion and the inclined portions are both located below the second waterproof cover.

[0014] The mounting plate, with its support and tilting parts, achieves a stable connection with the slider without affecting its sliding, while also providing space for the second waterproof cover, ensuring its stable placement between the slider and the mounting plate without affecting the normal use of the guide rail.

[0015] In the sealing structure of the worktable guide rail and lead screw described above, the connecting plate has an installation sleeve that fits onto the nut, the lower end of the installation sleeve has a horizontally set placement plate, the abutment plate of the waterproof cover is located above the placement plate, and the left and right sides of the placement plate have upwardly folded connecting parts, which are fixedly connected to the slide table.

[0016] The connecting plate has a mounting sleeve that fits onto the nut, allowing the mounting sleeve to be stably connected to the nut. The lower end of the mounting sleeve is equipped with a horizontally positioned placement plate, which can guide the liquid flowing out of the abutment plate and improve the stability of the waterproof cover.

[0017] In the sealing structure of the worktable guide rail and lead screw described above, the length of the connecting plate is less than the length of the mounting plate.

[0018] The connecting plate is fixed to the nut and is located between the mounting plates. Therefore, the weight at the connecting plate is reduced, which reduces the deformation in the middle of the slide and makes the sliding of the slide driven by the nut more stable.

[0019] Compared with existing technologies, the sealing structure of this worktable guide rail and lead screw has the following advantages: It adopts a split design, which, compared to the integrated design of waterproof cover one and waterproof cover two, facilitates installation and maintenance, reduces the driving force required for the motor to move the slide, and makes the rotation of the ball screw less strenuous. Furthermore, waterproof cover one and waterproof cover two are connected to the base, so they do not contact the slide during sliding. The installation of waterproof cover one and waterproof cover two is convenient and does not affect the waterproof effect of the ball screw and guide rail. Attached Figure Description
