Description

Multi-hole deep hole processing equipment modified by lathe

technical field

The utility model relates to the technical field of deep hole processing, in particular to a multi-hole deep-hole processing equipment transformed from an ordinary lathe, which is mainly used for deep-hole processing of a multi-hole part of a workpiece under one-time installation.

Background technique

At present, in mechanical processing, for deep hole processing, it is necessary to use a special deep hole drilling machine to complete. Due to the high cost and low utilization rate of deep hole drilling machines, most manufacturers rarely configure deep hole drilling machines, resulting in high and difficult deep hole processing costs. Lathes are widely used equipment in mechanical processing production. In order to reduce the cost of deep hole processing, it is proposed to transform the lathe so that it can realize deep hole processing, such as: "Ordinary lathe deep hole processing device (patent No.: CN201010504232.2)", although the processing range of ordinary lathes has been improved, and the cost of deep hole processing has been reduced, but this type of modified lathe deep hole drilling device can only process a single position hole under the condition of one installation, and cannot realize special deep hole drilling. The hole drilling machine is equipped with a multi-hole position processing function at one time.

Contents of the invention

In view of the above problems, the utility model provides a multi-hole deep hole processing equipment transformed from a lathe, which further expands the function of the lathe, realizes multi-hole processing on the workpiece, and improves work efficiency and quality.

The purpose of this utility model can be achieved through the following technical measures:

The multi-hole deep hole processing equipment transformed by the lathe of the utility model includes a lathe bed, a spindle box, a drill bit connected to the spindle of the spindle box through a drill sleeve, and a cutting fluid booster device, a ring sleeve, a drill sleeve, a workbench, A deep hole processing device composed of lower slide, upper slide, machine tool slide rail, bracket, and bracket slide rail. The drill bit is a hollow structure with a chip removal groove on the outer circumference. The ring sleeve is placed on the drill sleeve and connected with the air pressure pipe. , the end of which is fixedly connected to the spindle box, the input end of the cutting fluid booster device is connected to the air compressor, and the output end is connected to the ring sleeve through the air pressure tube; the machine tool slide rail is set on the upper surface of the lathe bed, and the lower plate On the slide rail of the machine tool, it is linked with the motor of the machine tool. The upper slide is set on the lower slide. A screw is set between the upper slide and the lower slide. One end of the screw is connected with a handwheel. It is connected on the support, a lead screw is arranged between the workbench and the support, and the handwheel is fixedly connected with one end of the lead screw.

The cutting fluid booster device described in the utility model is a gas-liquid booster pump, which is fixed on the spindle box; the machine tool slide rail is a dovetail groove structure; the upper slide plate is arranged on the lower slide plate through the dovetail groove slide rail.

The utility model is provided with the support slide rail on both sides of described support. A T-shaped slot is provided on the workbench.

The utility model is ingeniously conceived, changing the traditional concept of the workpiece rotating and the drill bit being fixed when the lathe is drilling in the past. The drill bit is directly installed on the main shaft to form a working form where the drill bit rotates and the workpiece is fixed, which greatly improves the relative speed of the drill bit and the workpiece. Improved drilling efficiency. Since the workbench has the function of adjusting the X-axis, Y-axis, and Z-axis, it can realize multi-hole machining on the workpiece, which further expands the function of the lathe. The installed booster device can spray high-pressure cutting fluid into the deep hole drill, which can not only increase the cutting lubrication and cooling effect, but also forcefully eject the chips through the chip flute—to avoid the accumulation of iron chips in the deep hole, It hinders the rotation of the drill bit, causing the relative twist of the drill bit and the drill shank, resulting in fracture.

Detailed ways

In conjunction with accompanying drawing, provide the embodiment of the present utility model as follows:

As shown in Fig. 1 in conjunction with Fig. 2: the multi-hole deep hole processing equipment of the lathe transformation described in the utility model is based on the structure of the lathe mainly composed of the lathe bed 13 and the headstock 1, on the lathe bed 13 is mainly composed of cutting fluid booster device 2, air pressure pipe 3, ring sleeve 4, drill sleeve 5, drill bit 6, workbench 7, lower slide 9, upper slide 10, machine tool slide rail 14, bracket 15, bracket slide rail 16 deep hole processing device. Headstock 1 is positioned at one side of lathe bed 13, and drill bit 6 is fixedly connected on the main shaft of headstock 1 through drill sleeve 5, and it is hollow structure, has chip removal groove on the outer circumference. The ring sleeve 4 is set on the left half of the drill sleeve 5, and can rotate relatively, and is connected with the air pressure pipe 3. During work, the drill sleeve 5 drives the drill bit to rotate, while the ring sleeve 4 remains fixed to ensure the stability of the air pressure pipe. The cutting fluid booster 2 (gas-liquid booster pump, etc.) is fixed on the spindle box 1, its input end is connected to the air compressor, and its output end communicates with the ring sleeve 4 through the air pressure tube 3. When in use, the high-pressure gas with cutting fluid is passed to the top of the hollow drill bit. Since the hole is a blind hole during the drilling process, the gas containing cutting fluid will remove the debris from the chip removal groove during the return process. Take it out of the discharge hole. A machine tool slide rail 14 is arranged on the upper end surface of the lathe bed 13, and the machine tool slide rail 14 has a dovetail groove structure. Sliding plate 9 is arranged on the machine tool slide rail 14, is driven screw by machine tool motor, connects sliding plate 9 by leading screw and slides left and right on machine tool slide rail 14. The upper slide plate 10 is arranged on the slide plate 9 and can move on the slide plate 9. In this embodiment, the dovetail slide rail is arranged on the slide plate 9, and a lead screw is set between the upper slide plate 10 and the slide plate 9, and the lead screw and the upper slide plate are threaded. Connect, rotate the leading screw by the hand wheel 12 to make the upper slide 10 move on the lower slide 9. The support 15 is fixed on the upper slide plate 10 by bolts, and the workbench 7 is slidably connected to the support 15 . As shown in Figure 2: the both sides of support 15 are provided with support slide rail 16, and the both sides of workbench 7 and support slide rail 16 are slidably connected, and lead screw is arranged between workbench 7 and support 15, and hand wheel 8 and wire One end of the bar is fixedly connected, and the workbench 7 is moved on the slide rail 16 by rotating the lead screw through the hand wheel 8 . There is a T-shaped slot on the workbench, which can be used to fix the workpiece with bolts such as V-shaped irons or directly on the workbench with bolts. Since the deep hole machining position on the workpiece is uncertain, there are usually various required deep hole machining positions. Therefore, the workbench needs to be adjusted freely in the directions of the X-axis, Y-axis, and Z-axis. When in use, the workpiece that requires deep hole processing is fixed on the workbench 7, and the slide plate 9 moves in the X-axis direction on the machine tool slide rail 14 through the lathe electric control device 11; Z-axis movement on the top; the worktable 7 moves in the Y-axis direction on the bracket slide rail 16 through the hand wheel 8, thus ensuring the freedom in the X, Y, and Z-axis directions, and realizing deep hole processing at different positions , and can perform deep hole processing at any position on the same workpiece.
