Description

Technical Field

[0001] This utility model relates to the field of machining center technology, specifically to a machining center equipped with an automatic chip collection device. Background Technology

[0002] Machining centers evolved from CNC milling machines. The biggest difference between them is that machining centers have the function of automatically changing machining tools. By installing tools for different purposes on the tool magazine, the machining tools on the spindle can be changed in one setup through an automatic tool changer, thus realizing multiple machining functions.

[0003] A search revealed a utility model patent with patent authorization announcement number CN108818012B, which discloses a CNC machining center. The purpose of this CNC machining center is to provide a CNC machining center that can clamp the next batch of parts while machining the previous part, thereby reducing clamping time and improving overall machining efficiency. The key technical point of this solution is that an isolation door is slidably connected inside the machining cavity, and the isolation door divides the machining cavity into an inner cavity and an outer cavity, with the tool holder located in the inner cavity.

[0004] When existing machining centers are in use, a large amount of waste is generated during the machining process, which needs to be cleaned in a timely manner. The usual cleaning method is to carry out the cleaning after the machining is completed, but the accumulation of waste will scratch the surface of the workpiece. Utility Model Content

[0005] The purpose of this invention is to provide a machining center with an automatic chip collection device, which solves the problem that existing machining centers lack chip collection functions.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a machining center with an automatic chip collection device, comprising a machining center housing, a chip removal mechanism provided on the top inner side of the machining center housing, a sliding plate fixedly connected to the inner wall of the machining center housing, a positioning seat fixedly connected to the inner wall of the machining center housing and below the sliding plate, a positioning block engaged inside the positioning seat, a collection groove fixedly connected to the end of the positioning block away from the positioning seat, a roller installed at the bottom of the collection groove, and the roller contacting the bottom inner side of the machining center housing.

[0007] Preferably, two guide seats are fixedly connected to the inner side of the slide plate, and the two guide seats are symmetrically arranged. The guide seats can guide the waste collected on the slide plate into the collection trough.

[0008] Preferably, a handle is welded onto the collection tank, and the handle is made of stainless steel. The handle facilitates the pulling of the collection tank.

[0009] Preferably, the positioning block has a sliding latch internally connected to a positioning seat, and the latch engages with the positioning seat. A spring is also provided inside the positioning block, with one end fixedly connected to the latch and the other end fixedly connected to the inner surface of the positioning block. The spring force acts on the latch, engaging it with the positioning seat, thereby positioning the collection groove.

[0010] Preferably, the chip removal mechanism includes a fixed base fixedly connected to the top inner side of the machining center housing. A motor is fixedly mounted on the outer side of the fixed base. The output shaft of the motor passes through the fixed base and is connected to the fixed base via a bearing. A threaded shaft is fixedly connected to the end of the output shaft. The other end of the threaded shaft is connected to the fixed base via a bearing. A movable block is threadedly connected to the outer side of the threaded shaft. An air pipe is fixedly connected to the bottom end of the movable block, and a nozzle is provided on the air pipe. The chip removal mechanism effectively cleans the waste chips on the tooling.

[0011] Preferably, the movable block is slidably connected to the inner side of the fixed base, and the movable block is square in shape. By setting the movable block to a square shape, it has a self-guiding effect on its axial movement on the threaded shaft.

[0012] Preferably, an air pump is fixedly installed on the top of the machining center housing. The output end of the air pump penetrates the machining center housing and extends to the inside of the housing. A flexible hose is fixedly connected to the end of the output end, and a connecting pipe is fixedly connected to the air hose. The connecting pipe is fixedly connected to the flexible hose. Air is delivered into the air hose through the flexible hose and the connecting pipe by the air pump.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model provides a chip removal mechanism on the inner side of the machining center's outer shell. The mechanism is achieved by driving a threaded shaft with an electric motor, which causes the moving block to move laterally periodically. This movement of the moving block then causes the air pipe to move laterally. The air pump delivers air to the air pipe, which is then pressurized by the nozzle and ejected to promptly remove the chips from the tooling table of the machining center, thus preventing scratches on the workpiece.

[0015] 2. This utility model features an inclined sliding plate on the inner rear side of the machining center's outer shell, with two guide seats on the plate's cover. Additionally, a movable collection trough is located below the tooling table, with the collection trough corresponding to the guide seats. This, combined with the blowing action of the chip removal mechanism, allows waste chips to fall along the inner wall of the machining center's outer shell into the sliding plate, and then slide into the collection trough for unified collection, preventing waste chips from scattering and improving the efficiency of waste chip collection.

A spring 10 is installed inside the positioning block 5. One end of the spring 10 is fixedly connected to the locking pin 9, and the other end of the spring 10 is fixedly connected to the inner surface of the positioning block 5. The elastic force of the spring 10 can act on the locking pin 9, causing it to engage with the positioning seat 4, thereby positioning the collection groove 6. The end of the positioning block 5 away from the positioning seat 4 is fixedly connected to the collection groove 6. A roller 7 is installed at the bottom of the collection groove 6, and the roller 7 contacts the inner bottom of the machining center housing 1. A handle 8, made of stainless steel, is welded onto the collection groove 6. The handle 8 facilitates the pulling of the collection groove 6.

[0026] Please see Figure 1 , Figure 2 , Figure 4 , Figure 5 A chip removal mechanism 2 is provided on the top inner side of the machining center housing 1. This mechanism cleans debris from the tooling. The chip removal mechanism 2 includes a fixed base 21 fixedly connected to the top inner side of the machining center housing 1. A motor 22 is fixedly mounted on the outer side of the fixed base 21. The output shaft of the motor 22 passes through the fixed base 21 and is connected to it via a bearing. A threaded shaft 23 is fixedly connected to the end of the output shaft. The other end of the threaded shaft 23 is connected to the fixed base 21 via a bearing. A movable block 24 is threadedly connected to the outer side of the threaded shaft 23. An air pipe 25 is fixedly connected to the bottom end of the movable block 24, and a nozzle 26 is provided on the air pipe 25. The chip removal mechanism 2 cleans debris from the tooling.
