Description

Technical Field

[0001] This utility model belongs to the field of lathe protection technology, specifically relating to an external protection for a common horizontal lathe. Background Technology

[0002] Ordinary horizontal lathes (such as the CDE-A series) have a mature structure and can machine a variety of feature parts. This equipment adopts an open structure, with the spindle, motion mechanism, cutting tools, and workpiece system directly visible and accessible. While this provides convenient operability, the exposed work area means that during machining, cutting forces cause chips to fly at speeds of tens of meters per second, potentially injuring the operator's eyes, face, and hands, and in severe cases, causing blindness or lacerations. Long-term inhalation of the metal dust and cutting fluid mist generated during cutting can cause respiratory illnesses, and dust accumulation can easily lead to fire hazards. Furthermore, components such as the spindle and chuck of ordinary lathes are often exposed, and operators may accidentally touch them, leading to entanglement accidents.

[0003] In existing technologies, fully enclosed protective shields are often used for protection. The disadvantages of fully enclosed protective shields include: (1) A fully enclosed protective cover may obstruct the operator's view and increase the difficulty of adjusting the workpiece or tool.

[0004] (2) Although a fully enclosed protective cover can reduce the entry of chips, it may lead to excessively high internal temperature. Existing heat dissipation solutions (such as electric fans) are prone to clogging in dusty or oily environments, affecting heat dissipation efficiency and even accelerating the aging of components.

[0005] (3) Similar to the fully enclosed protection used in CNC machine tools, the production cost of the external protective device is high and the installation is relatively complicated. The visual operation of fully enclosed protection is smaller in terms of operating space and visual range compared to the open operation of ordinary lathes.

[0006] (4) The maintenance cost and complexity of fully enclosed protection are high. Protective devices (such as guide rail roller shutters and steel plate protective covers) need to be cleaned, lubricated and inspected regularly. The disassembly process is complicated and not easy to operate. Summary of the Invention

[0007] To address the aforementioned technical problems, this utility model provides an external protective cover for a common horizontal lathe.

[0008] This utility model is achieved through the following technical solution: An external protective cover for a conventional horizontal lathe, comprising: an L-shaped protective cover, a linear guide rail, and a guide shaft; The linear guide rail and the guide shaft are both mounted on the upper part of the lathe headstock, and are arranged in parallel. One end of the L-shaped protective cover has a protruding connecting part on the side near the headstock of the lathe, and is slidably connected to the guide shaft through the protruding connecting part; the bottom of the L-shaped protective cover and the linear guide rail are connected by a snap fastener. The guide shaft is arranged along the length of the lathe bed and is located at the rear of the upper part of the lathe headstock; both ends of the guide shaft are connected to the lathe headstock via a guide shaft support. An observation window is provided on the L-shaped protective cover.

[0009] Furthermore, the protruding connecting part and the guide shaft are connected by a linear bearing mounting seat.

[0010] Furthermore, the guide shaft support and the lathe headstock are detachably connected.

[0011] Furthermore, two upper buckles are provided below the L-shaped protective cover; Two lower latches are provided on the linear guide rail; The L-shaped protective cover and the linear guide rail are connected by the upper buckle and the lower buckle.

[0012] Furthermore, the lower buckle is slidably connected to the linear guide rail via a linear guide rail slider.

[0013] Furthermore, a limit switch is provided at one end of the linear guide rail near the machining position; the limit switch is fixed to the linear guide rail by a limit switch fixing block; The limit switch is connected to the circuit board of the ordinary horizontal lathe.

[0014] Furthermore, the observation window is located on the side of the L-shaped protective cover near the front of the lathe bed.

[0015] Furthermore, the observation window is made of transparent protective glass.

[0016] Furthermore, a handle is provided on the L-shaped protective cover.

[0017] The beneficial technical effects of this utility model are as follows: The external protective cover for a conventional horizontal lathe provided by this utility model ensures that the lathe can only be started when the L-shaped protective cover is fully pulled to the working area position, thus preventing accidents caused by misoperation.

[0018] The external protection for a conventional horizontal lathe provided by this utility model is a semi-protective system. While providing physical isolation and blocking cutting fluid and debris splashes to achieve the protection function, a transparent protective glass is set on the protective cover to provide the operator with sufficient visibility space, so that the ease of operation is not affected.

[0019] The external protective cover for a conventional horizontal lathe provided by this utility model can be lifted by the snap-fit ​​between the upper buckle of the protective cover and the lower buckle of the linear guide rail, combined with the rotation of the protective cover and the guide shaft. After being opened by lifting, the protective cover can be quickly disassembled by removing the guide shaft support. The easy-to-disassemble protective cover structure makes maintenance, upkeep and cleaning operations more convenient.

[0020] The external protection of the ordinary horizontal lathe provided by this utility model is a semi-enclosed design, which not only reduces the entry of chips, but also prevents the internal temperature from becoming too high. Attached Figure Description

Furthermore, to provide the public with a better understanding of this utility model, certain specific details are described in detail in the following description. However, those skilled in the art will fully understand this utility model even without these detailed descriptions.

[0024] This utility model provides an embodiment of an external protective cover for a common horizontal lathe, which includes: an L-shaped protective cover 1, a linear guide rail 11, and a guide shaft 9; The linear guide rail 11 and the guide shaft 9 are both installed on the upper part of the lathe headstock, and the two are arranged in parallel. One end of the L-shaped protective cover 1 has a protruding connecting part on the side near the headstock of the lathe, and is slidably connected to the guide shaft 9 through the protruding connecting part; the bottom of the L-shaped protective cover 1 and the linear guide rail 11 are connected by a snap fastener. The guide shaft 9 is arranged along the length of the lathe bed and is located at the rear of the upper part of the lathe headstock; both ends of the guide shaft 9 are connected to the lathe headstock through a guide shaft support 10, respectively. An observation window 2 is provided on the L-shaped protective cover 1.

[0025] In this embodiment, the protruding connecting portion and the guide shaft 9 are connected by a linear bearing mounting base 8. Therefore, the L-shaped protective cover 1 can slide along the guide shaft 9 and can rotate relative to the guide shaft 9.

[0026] In this embodiment, the guide shaft support 10 and the lathe headstock are detachably connected.

[0027] In this embodiment, two upper buckles 4 are provided below the L-shaped protective cover 1; Two lower latches 5 are provided on the linear guide rail 11; The L-shaped protective cover 1 and the linear guide rail 11 are connected by the upper buckle 4 and the lower buckle 5.
