Description

Technical Field

[0001] The utility model relates to the technical field of milling, drilling and tapping machines, in particular to a milling, drilling and tapping dual-axis compound machine. Background Art

[0002] A tapping machine is a machining equipment for machining internal threads, screws or threads on the inner side surfaces of through holes or blind holes, part holes of various specifications such as machine part shells, equipment end faces, nuts, flange plates, etc. The tapping machine is also called a thread tapping machine, a screw tapping machine, an automatic tapping machine, etc. The processing of shaft-shaped workpieces (such as the cylindrical part in a bathroom handle) requires milling, drilling and tapping operations, which need to be completed one by one on a milling machine, a drilling machine and a tapping machine respectively, and the overall processing efficiency is not high enough.

[0003] A milling, drilling and tapping dual-axis compound machine disclosed in the existing patent (Publication No.: CN214186076U) includes a machine frame. A milling and drilling integrated module, a tapping module and a station conversion module for switching the workpiece from the milling and drilling integrated module to the tapping module are arranged on the machine frame. The workpiece position can be quickly switched between the milling and drilling integrated module and the tapping module through the station conversion module. The milling and drilling integrated module can simultaneously perform surface milling and hole opening on the workpiece, and it taps the workpiece in the opened hole through the tapping module, integrating the three processing operations on the same piece of equipment, thus improving the overall processing efficiency.

[0004] However, the above technical solution still has certain defects. The above technical solution sets two output ends on the machine table. The workpiece is milled under one output end, and then moved under the other output end for tapping. This technical solution causes a substantial increase in the production cost of the machine table, and the workpiece position needs to be calibrated again after being moved under the other output end, resulting in a reduction in processing efficiency. Therefore, a milling, drilling and tapping dual-axis compound machine is proposed. Content of the Utility Model

[0005] Based on this, the purpose of the present utility model is to provide a milling, drilling and tapping dual-axis compound machine to solve the technical problems raised in the above background.

[0007] The tool changing mechanism includes a connecting head, which is fixedly connected to the outer wall of the machine table body. The connecting head is sleeved outside the output end of the machine table body. The bottom end of the connecting head is fixedly connected with a connecting plate. Two groups of sliding grooves are opened at the bottom end of the connecting plate. A group of sliders are respectively slidably sleeved on the inner walls of each group of sliding grooves. The two groups of sliders are arranged oppositely. A group of rotating sleeves are respectively rotatably connected to the side walls of each group of sliders. A milling cutter is fixedly connected to the bottom end of one group of rotating sleeves, and a tap is fixedly connected to the bottom end of the other group of rotating sleeves. An opening is opened at the top end of the rotating sleeve, and the output end of the machine table is in conformity with the opening.

[0008] As a preferred technical solution of the milling, drilling and tapping double-axis compound machine of the present utility model, two connecting bars are fixedly connected to both sides of the two groups of sliders. A group of limiting rods are respectively sleeved at both ends of the two connecting bars. Two limiting rings are fixedly connected to the bottom end of the connecting plate, and the two limiting rings are respectively close to both ends of the connecting plate.

[0009] As a preferred technical solution of the milling, drilling and tapping double-axis compound machine of the present utility model, a group of return springs are respectively sleeved on the outer walls of each group of limiting rods. One end of the return spring is fixedly connected to the outer wall of the limiting rod, and the other end of the return spring is fixedly connected to the side wall of a connecting bar.

[0010] As a preferred technical solution of the milling, drilling and tapping double-axis compound machine of the present utility model, a support table is arranged on the outer wall of the machine table body, and a group of suction mechanisms are respectively fixedly connected to both ends of the support table.

[0011] As a preferred technical solution of the milling, drilling and tapping double-axis compound machine of the present utility model, the suction mechanism includes a housing.

[0014] In summary, the present utility model mainly has the following beneficial effects:

[0015] 1. After the workpiece is milled by the present utility model, pushing the slider to slide can quickly replace the milling cutter with a tap, thus eliminating the need to set two output ends on the machine tool body, reducing the manufacturing cost of the machine tool body. And since the same output end is used, the workpiece does not need to be repositioned for tooling, improving the processing efficiency.

[0025] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The embodiments described below with reference to the accompanying drawings are exemplary only for explaining the present utility model and should not be construed as limiting the present utility model.

[0026] The embodiments of the present utility model will be described below according to its overall structure.

[0027] A milling, drilling and tapping dual-axis compound machine, as Figures 1 to 5 shown, includes a machine table main body 1, and a tool changing mechanism 2 is fixedly connected to the output end of the machine table main body 1;

[0028] The tool changing mechanism 2 includes a connecting head 201, the connecting head 201 is fixedly connected to the outer wall of the machine table main body 1, the connecting head 201 is sleeved outside the output end of the machine table main body 1, the bottom end of the connecting head 201 is fixedly connected to a connecting plate 202, two groups of sliding grooves 203 are opened at the bottom end of the connecting plate 202, a group of sliding blocks 204 are respectively slidably sleeved on the inner walls of each group of sliding grooves 203, the two groups of sliding blocks 204 are arranged oppositely, a group of rotating sleeves 205 are respectively rotatably connected to the side walls of each group of sliding blocks 204, a milling cutter 207 is fixedly connected to the bottom end of a group of rotating sleeves 205, a tapping die 208 is fixedly connected to the bottom end of the other group of rotating sleeves 205, an opening 206 is opened at the top end of the rotating sleeve 205, the output end of the machine table is fitted with the opening 206, two groups of connecting bars 209 are fixedly connected to both sides of the two groups of sliding blocks 204, a group of limiting rods 210 are respectively sleeved at both ends of the two groups of connecting bars 209, two groups of limiting rings 211 are fixedly connected to the bottom end of the connecting plate 202, the two groups of limiting rings 211 are respectively close to both ends of the connecting plate 202, a group of return springs 212 are respectively sleeved on the outer walls of each group of limiting rods 210, one end of the return spring 212 is fixedly connected to the outer wall of the limiting rod 210, the other end of the return spring 212 is fixedly connected to the side wall of a group of connecting bars 209, an inclined surface is arranged at the end of the limiting rod 210, and the end of the limiting rod 210 is fitted with the inner wall of the limiting ring 211.

[0029] By sleeving the openings 206 on a set of rotating sleeves 205 on the output end of the machine table main body 1, during the rotation of the output end of the machine table main body 1, this set of rotating sleeves 205 is driven to rotate, and this set of rotating sleeves 205 drives the milling cutter 207 to rotate, so as to perform milling processing. When tapping processing is required, by pushing the limiting rod 210 close to the side of the tap 208 to slide out from the inside of the limiting ring 211, the return spring 212 on this side is compressed, and then the slider 204 on one side is pushed, so that this set of sliders 204 pushes the connecting bar 209, and the connecting bar 209 drives the other set of sliders 204 to move, so that the set of rotating sleeves 205 connected to the milling cutter 207 is separated from the output end of the machine table main body 1, and the rotating sleeves 205 connected to the tap 208 approach the output end of the machine table main body, so that the openings 206 on this set of rotating sleeves 205 are sleeved on the output end of the machine table main body 1, so that the output end of the machine table main body 1 can drive the tap 208 to rotate. During the above process, the limiting rod 210 close to the side of the milling cutter 207 contacts the limiting ring 211, so that the inclined surface on the limiting rod 210 contacts the limiting ring 211. At this time, the limiting ring 211 pushes the limiting rod 210, so that the limiting rod 210 compresses the return spring 212. When the limiting rod 210 is aligned with the inner wall of the fiber ring, the return spring 212 rebounds and pushes the limiting rod 210 to reset, so that the limiting rod 210 is inserted into the inside of the limiting ring 211, so that the two sets of sliders 204 cannot slide.

[0030] Please refer particularly to Figure 1 and Figure 5 On the outer wall of the machine table main body 1, there is a support table 3. At both ends of the support table 3, a set of suction mechanisms 4 are respectively fixedly connected. The suction mechanism 4 includes a housing 401. An air inlet is opened at a position near the top on one side of the housing 401. A collection net 402 is fixedly connected to one end of the inner wall of the housing 401 near the air inlet. A fan 404 is fixedly sleeved at a position near the bottom of the inner wall of the housing 401. Two sets of filter plates 403 are fixedly sleeved on the inner wall of the housing 401. The two sets of filter plates 403 are located between the collection net 402 and the fan 404.

[0031] The fan 404 drives the air flow to enter the housing from the air inlet, and then these air flows pass through the collection net 402 and the filter plates 403, so that the debris on the support table 3 is sucked into the inside of the housing. The larger particles of debris are filtered out by the collection net 402, and then the finer debris is filtered out by the two sets of filter plates 403, thus avoiding some fine debris from floating into the air and being inhaled by the staff, and at the same time facilitating the cleaning of the debris.

[0032] During use, after milling the workpiece, pushing the slider 204 to slide can quickly replace the milling cutter 207 with the tap 208. Thus, there is no need to set two sets of output ends on the machine tool body 1, reducing the manufacturing cost of the machine tool body 1. Moreover, since the same output end is used, the workpiece does not need to be repositioned for tool setting, improving the processing efficiency. The parts not involved in this device are the same as or can be implemented using the prior art.

The specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
