Description

An automatic device for drilling and tapping of porous parts

technical field

The utility model belongs to the technical field of machining, in particular to an automatic device for drilling and tapping of porous parts.

Background technique

With the shortage of labor and the increase of labor costs, processing enterprises have adopted the method of replacing human beings with machines to cope with the situation of labor difficulties, so that factories can realize automatic production, so as to improve the processing quality of products, speed up product production efficiency and reduce product production costs. Among them, threaded connection is the main connection method of industrial products, and drilling and tapping on product parts occupy a large proportion in the production process of products. For example, the panel on the smart lock needs to open several mounting holes on the panel. In order to improve the machining accuracy and efficiency of the mounting holes, the drilling and tapping machine came into being. And the drilling and tapping machine is generally equipped with a tool magazine to change the tool, and the installation holes are drilled, tapped or processed with different diameters by different tools.

As shown in "Drilling and Tapping Machine with Gear-type Tool Magazine" disclosed in the utility model patent with the patent number of ZL201620413660.7 (announcement number of CN205733799U), the drilling and tapping machine is realized by rotating the tool magazine through gear transmission. The tool change function, but the gear transmission can easily cause the tool magazine to not rotate in place, so that the tool cannot be completely aligned with the hole to be processed, thereby affecting the processing of the workpiece.

In addition, the table of the drilling and tapping machine can only move back and forth relative to the base, and the machine head can only move up and down relative to the frame. If the tool is not aligned with the hole to be processed, it is inconvenient to adjust, resulting in low machining accuracy. ; And, for holes with different positions and different diameters on the workpiece, the workpiece may need to be clamped multiple times to adapt to the processing of the drilling and tapping machine.

Or as shown in "A Double Link Tool Changing Device" disclosed in the invention patent with the patent number ZL201710198612.X (publication number CN106826335A), it includes several sets of tool changing components, a main shaft and a base, and the main shaft passes through the The middle of the base can move up and down, and several sets of tool change assemblies are arranged around the main shaft. The fixed seat at the bottom of the seat is movably connected, and the other end of the double connecting rod is connected with the horizontally arranged tool clip. Level. Each group of tool change components is controlled independently, and you can select the tool holder under any group of tool change components and the tool holder under the spindle to switch to realize tool change.

Because the position of the main shaft is fixed, the position of the tool mounted on the main shaft is also fixed, and the problem of inaccurate positioning of the tool and inability to align the hole position will not occur. However, when one set of tool change assemblies is stowed away, it is still located on one side of the spindle and is relatively close to the spindle, which may easily lead to the other set of tool change assemblies working, if the movement stroke of the tool card is larger, it will be different from that of the previous set. The retracted tool changer assembly interferes, and the structure is not compact enough; in addition, when the tool changer assembly is retracted, its position is relatively lower, and the tool card and the tool clamped by the tool card are always located under the base, so that during processing When working on a workpiece, if the surface of the workpiece is uneven, the higher position is likely to interfere with the tool holder or the tool clamped by the tool holder.

Utility model content

The technical problem to be solved by the utility model is to provide an automatic device for drilling and tapping of porous parts in which the tool can always be aligned with the hole to be processed for processing according to the current state of the prior art.

The technical scheme adopted by the utility model to solve the above technical problems is: an automatic device for drilling and tapping of porous parts, which is characterized in that: comprising:

workbench;

The turntable is arranged on the worktable and can be rotated horizontally relative to the worktable. A plurality of operation stations are arranged at intervals along the circumferential direction adjacent to the edge of the turntable, and each operation station is respectively provided with a clamp for positioning the workpiece;

At least two working mechanisms are arranged on the worktable and adjacent to the edge of the turntable. Each working mechanism includes a moving mechanism and a tool-changing mechanism that is arranged on the moving mechanism and can move synchronously with the moving mechanism. The moving mechanism can move up and down relative to the clamp, Moving back and forth and left and right, the tool changing mechanism includes a spindle mechanism for clamping the tool and at least two sets of tool changing assemblies for switching the tool for the spindle mechanism.

In order to avoid multiple clamping of workpieces or multiple tool replacements, each tool changing assembly on the same tool changing mechanism corresponds to different processing procedures of the same hole, so that the same hole can be completed in one operation station. In the machining process, there is no need to manually change the tool or clamp the workpiece for many times, which improves the machining accuracy and efficiency. In other words, one group of tool change assemblies on the same tool change mechanism can perform drilling, and the other group of tool change assemblies on the same tool change mechanism can perform tapping and the like.

In order to avoid multiple clamping of the workpiece or multiple tool replacements, two adjacent working mechanisms correspond to holes with different diameters, so that with one cycle of the turntable, the holes with different diameters on the workpiece can be processed, and the machining accuracy is high. and high efficiency.

The tool changing mechanism can have various structural forms. Preferably, the spindle mechanism includes a spindle frame and a main shaft, the lower part of the main shaft extends out of the main shaft frame, and the bottom of the main shaft has a clamping port for clamping the tool, The clamping port and the tool are kept on the same axis, and the tool changing assemblies are evenly distributed along the outer side wall of the spindle frame. The outer side of the spindle frame avoids interference with the spindle, so that the tool changer assembly can be prevented from interfering with other components in the stowed state.

The tool changing mechanism may have various structural forms, preferably, each tool changing assembly includes a

a first driving mechanism, comprising a first driving member and a first push rod that is driven by the first driving member to move up and down, the first driving member is arranged on the outer side wall of the spindle frame;

The second driving mechanism includes a second driving member and a second push rod that is driven by the second driving member to move up and down, and the second driving member is drivingly connected to the power output end of the first push rod;

A clamping mechanism for clamping a tool, the first end of the clamping mechanism is rotatably connected with the output end of the first push rod, and the second end of the clamping mechanism is provided with a clamping portion for clamping the tool, so The middle part of the clamping mechanism is rotatably connected with the first end of a connecting piece, and the second end of the connecting piece is rotatably connected with the power output end of the second push rod.

The tool changing assembly has a simple structure, and the cooperation of various components makes the tool changing action fast and reliable, and when the tool changing mechanism is not working, the first push rod, the second push rod and the clamping mechanism can be completely retracted and kept away from the electric spindle to Prevent interference with the electric spindle and the tool on the electric spindle.

In order to further ensure that the tool changing mechanism is away from the electric spindle when it is retracted, the second driving member is located outside the first driving member.

In order to prevent the clamping mechanism or the tool on the clamping mechanism from interfering with the workpiece due to the lower position of the clamping mechanism when the tool changing mechanism is retracted, the bottom surfaces of the first driving member and the second driving member are higher than the bottom surface of the spindle frame. If the surface of the workpiece is uneven, the higher position is very likely to interfere with the clamping mechanism or the tool on the clamping mechanism.

In order to facilitate the driving connection between the second driving member and the power output end of the first push rod, the second driving member is connected with the output end of the first push rod through a connecting frame, and the first push rod of the clamping mechanism is connected to the first push rod. The end is hinged to the connecting frame. The arrangement of the connecting frame not only facilitates the assembly of the first driving member, the second driving member and the clamping mechanism, but also enables the second driving member to run smoothly when driven by the first push rod. And if there is no connecting frame, and the second driving member is arranged at the lower end of the first push rod, when the tool changing mechanism is retracted, the position of the tool clamped by the clamping mechanism will be relatively lower, and it is easy to match the workpiece when machining the workpiece. The workpiece interferes.

In order to further improve the running stability when the second driving member is driven by the first push rod, the connecting frame and the first driving member are slidably connected through a sliding rail structure. The arrangement of the slide rail structure not only makes the second driving member run smoothly, but also positions and guides its running track. If the second driving member has a running deviation, it is very likely that the clamping mechanism cannot be accurately matched with the electric spindle. Change the knife.

In order to keep the clamping mechanism away from the main shaft to avoid interference with the tool on the main shaft when the tool changing mechanism is retracted, preferably, the clamping mechanism includes a rear section, a front section, and a middle section connecting the rear section and the front section, the rear section. The segment is rotatably connected with the first push rod, the connection between the front segment and the middle segment is rotatably connected with the first end of the connector, the clamping portion is provided at the end of the front segment, and the clamping portion between the rear segment and the middle segment is rotatably connected. The angle is an obtuse angle, and the angle between the middle section and the front section is an obtuse angle. The clamping mechanism has a simple structure and is easy to manufacture. Of course, the clamping mechanism can also be of other structures, as long as it does not interfere with the electric spindle when retracted.

To facilitate clamping the tool, the clamping portion includes a concave portion opened at the end of the front section, and two opposite side walls of the concave portion are provided with clamping members for positioning the tool in the groove.

In order to reduce the volume of the tool, the head of the tool is in the shape of a truncated cone with a small upper part and a large lower part, so that the upper part of the tool can be directly clamped by the spindle without the need for a tapered tool handle.

Compared with the prior art, the advantages of the present utility model are as follows: 1. The working mechanism of the present utility model can adjust the position of the tool changing mechanism by setting the moving mechanism and the tool changing mechanism for clamping the tool that moves synchronously with the moving mechanism. , so that the clamping port of the spindle mechanism always faces the workpiece, so that the tool can always be aligned with the hole to be machined on the workpiece, and the machining accuracy is improved; Each part of the tool assembly is located on the outer side of the spindle frame and away from the spindle, so that it will not interfere with the spindle and the tool clamped by the spindle; and the clamping port of the spindle and the tool are kept on the same axis, and the spindle can always be located in the waiting position. Just above the machining hole, so there will be no problem of machining deviation caused by misalignment between the tool and the hole; 3. The bottom surfaces of the first driving part and the second driving part of the tool changing mechanism are higher than the bottom surface of the spindle frame, so In the state where the tool change assembly is finished and folded, the components of the tool change mechanism and the tool on the tool change mechanism can be in a higher position relative to the spindle, so that when the tool on the spindle processes the workpiece, the tool change mechanism and The tool on it will not interfere with the workpiece.
