Description

Technical Field

[0001] The utility model relates to the technical field of lathes, and particularly relates to a lathe for casting processing which is convenient for cleaning waste chips. Background Art

[0002] A lathe is a precision machining equipment integrating structures such as a bed, a headstock, a feed system, a tool rest, etc. During the machining of the lathe, a large amount of waste chips will be generated, and the cleaning is relatively difficult. For the existing lathes for casting processing, it is inconvenient to separate waste materials and iron chips, and the cleaning efficiency of waste materials is low.

[0003] The Chinese patent discloses a lathe for casting processing which is convenient for cleaning waste chips (the authorization announcement number is CN217966084U). Through the scraping mechanism provided by the utility model and the action of the waste material collection box, the waste materials and iron chips can be separated and classified for collection, greatly improving the working efficiency.

[0004] Since the above lathe performs processing operations in an exposed environment, during the rotary processing of the casting, the waste chips generated by cutting will splash around under the action of centrifugal force. However, the above device can only clean the waste chips that fall on the lathe chassis, and the cleaning range is small. The staff needs to actively clean and process the waste chips that splash outside the lathe chassis, increasing the cleaning burden of the staff.

[0005] Therefore, a lathe for casting processing which is convenient for cleaning waste chips is proposed to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a lathe for casting processing which is convenient for cleaning waste chips to solve the above problems, and improve the problem that the cleaning range of the lathe for casting processing which is convenient for cleaning waste chips is small, and the staff still needs to actively clean and maintain.

[0007] The utility model realizes the above purpose through the following technical solutions. A lathe for casting processing which is convenient for cleaning waste chips includes: a bed, one end of the bed is fixedly connected with a headstock, an electric slide rail is fixedly connected to the top of the bed, a tool rest is installed on the surface of the electric slide rail, and a cutting tool is fixedly connected to the surface of the tool rest; a protection device, and the protection device is installed between the headstock and the tool rest.

[0008] Preferably, the protection device includes a cylinder and a sealing frame. The cylinder is fixedly connected to one end of the spindle box. The output shaft of the spindle box is arranged inside the cylinder. The sealing frame is slidably connected to the surface of the cutting tool. One end of the sealing frame is in contact with the cylinder. The bottom of the cylinder is fixedly connected and communicated with a chip discharge pipe. Before the cutting tool cuts and rotates the casting, the tool rest can drive the sealing frame to fit together with the cylinder. At this time, the cutting tool can still move forward normally to ensure that the casting can be cut normally. However, at this time, both ends of the cylinder are sealed by the spindle box and the sealing frame respectively, which can limit the waste chips generated by cutting the casting inside the cylinder and avoid the probability of waste chips splashing around under the action of centrifugal force, thereby reducing the burden on the staff for subsequent cleaning.

[0009] Preferably, the diameter of the sealing frame is larger than the inner diameter of the cylinder. The opposite end surfaces of the sealing frame and the cylinder are flat and smooth. After the cutting tool adjusts its position, the sealing frame can still effectively block one end of the cylinder at this time, so as to expand the protection range of the protection device.

[0010] Preferably, the cross-sectional shape of the inner bottom wall of the cylinder is V-shaped, and the top of the chip discharge pipe is communicated with the lowest point of the inner bottom wall of the cylinder, which can guide the waste chips staying inside the cylinder into the chip discharge pipe to reduce the retention amount of waste chips inside the cylinder.

[0011] Preferably, one end of the chip discharge pipe is fixedly connected and communicated with a dust filter bag. The dust filter bag is arranged at the lowest point of the chip discharge pipe. The dust filter bag can collect the waste chips together, which is convenient for the staff to clean them centrally, so as to achieve the effect of facilitating the cleaning of waste chips.

[0012] Preferably, an external thread sleeve is fixedly connected to the surface of the chip discharge pipe, and an internal thread sleeve fixedly connected to the dust filter bag is threadedly connected to the surface of the external thread sleeve, which can make the dust filter bag detachable and further facilitate the cleaning of waste chips.

[0013] Preferably, a spring sleeved on the surface of the cutting tool is fixedly connected between the tool rest and the sealing frame. The spring is in a compressed state at this time. The spring can make the cylinder and the sealing frame fit more tightly to reduce the probability of generating gaps between the cylinder and the sealing frame.

[0014] Preferably, a fan is fixedly connected and communicated with the top of the cylinder. The fan and the chip discharge pipe are symmetrically distributed on both sides of the axis of the cylinder. The fan can blow air into the cylinder. When the high-speed air flow passes through the cylinder, it can not only reduce the heat generated during the cutting of the cutting tool and the casting to achieve the purpose of reducing overheating, but also the high-speed air flow can carry the waste chips through the chip discharge pipe and the dust filter bag in turn. The dust filter bag intercepts the waste chips in the passing air flow for recycling.

[0015] Preferably, a protective net is embedded at the connection between the cylinder and the fan. The protective net is made of stainless steel, which can reduce the probability of waste chips flying into the fan interior and ensure the integrity of the fan.

[0016] The beneficial effects of the present utility model are as follows:

[0017] 1. Before the cutting tool cuts the rotating casting, the tool rest can drive the sealing frame to fit with the cylinder. At this time, the cutting tool can still move forward normally to ensure that the casting can be cut normally. However, at this time, both ends of the cylinder are sealed by the main spindle box and the sealing frame respectively, which can confine the waste chips generated by cutting the casting within the cylinder and avoid the probability of waste chips splashing around under the action of centrifugal force, thereby reducing the burden of subsequent cleaning for the staff;

[0018] 2. The fan can blow air into the cylinder. During the process of the high-speed air flow passing through the cylinder, it can not only reduce the heat generated when the cutting tool and the casting are cut to achieve the purpose of reducing overheating, but also the high-speed air flow can carry the waste chips through the chip removal pipe and the dust filter bag in sequence. The dust filter bag intercepts the waste chips in the passing air flow for recycling. BRIEF DESCRIPTION OF THE DRAWINGS
