Description

Technical Field

[0001] The utility model belongs to the field of fixture structures, and particularly relates to a fixture structure. Background Art

[0002] In machining, the drilling process is often involved. In the drilling process, the workpiece to be machined needs to withstand very large lateral and radial forces of the drill bit. Therefore, it is necessary to fix the workpiece to be machined, and the common fixing method is to fix it through a fixture.

[0003] Fixtures usually use mechanical, hydraulic and other structures. During the drilling process, a large amount of debris will fall off. The debris will enter the fixture structure, thus affecting the mechanical performance of the fixture. Especially when the workpiece is on top and the fixture is at the bottom, more debris will enter the fixture structure. Thus, the following problems exist:

[0004] 1. The adhesion of debris to the fixture will affect the clamping position of the workpiece, and further affect the drilling position, thereby reducing the yield rate, especially for workpieces with strict requirements for drilling accuracy;

[0005] 2. The accumulation of debris affects the movement of the mechanical structure, such as the threaded movement structure, and further causes jamming of the fixture, reducing the processing efficiency.

[0006] Therefore, it is necessary to remove the debris in the fixture. The traditional cleaning method is to blow with air or continuously rinse with liquid outside. However, the cleaning effects of the above two methods are not good, and there is unclean cleaning. Especially when the fixture is located below the workpiece, driven by air and liquid, and due to the gravity effect, some debris will inevitably still enter the fixture interior and is not easy to clean out. With the accumulation of debris, the above problems will occur. Summary of the Utility Model

[0007] In order to overcome the deficiencies of the prior art, the utility model provides a fixture structure to solve the problem that the current installation of a blowing or liquid structure outside cannot completely remove debris, resulting in affecting the accuracy and mechanical performance of the fixture, especially when the fixture is located below the workpiece.

[0008] A fixture structure according to an embodiment of the utility model includes:

[0009] A carrier;

[0010] A fixture structure, which is installed on the carrier;

[0011] A water inlet structure, which is installed on the carrier. An inlet water pipe is arranged inside the carrier, and the water inlet structure is communicated with a plurality of the fixture structures through the inlet water pipe.

[0012] A fixture structure of the present utility model, the bearing member is used to receive external drilling materials, the drilling materials are clamped by the fixture structure, and debris will penetrate into the fixture structure during drilling. At this time, the water inlet structure is connected to an external water pump, and water is introduced into the water inlet pipe through the external water pump. Finally, the water will spray out from the fixture structure, so as to discharge the debris entering the fixture structure through the water flow. The unexpected effect is achieved through the cooperation of the water inlet pipe and the fixture structure, and the water flow can also cool the drill bit during drilling.

[0013] According to some embodiments of the present utility model, a water outlet nozzle is provided at the end of the pipe, and a nozzle is provided on the nozzle.

[0014] According to some embodiments of the present utility model, there are at least three nozzles, which are respectively located in the middle and around the nozzle. Among them, the nozzles located around are inclined.

[0015] According to some embodiments of the present utility model, a blocking block is provided at the end of each water inlet pipe communicating with the fixture structure to reduce the diameter of the outlet position of the water inlet pipe and increase the liquid pressure.

[0016] According to some embodiments of the present utility model, the blocking block is an annular conical block, and the annular conical block is inclined inward.

[0017] According to some embodiments of the present utility model, the blocking block is threadedly connected in the pipe where the water inlet pipe communicates with the fixture structure.

[0018] According to some embodiments of the present utility model, the fixture structure includes an annular mounting member, a clamping arm assembly and a fastening assembly.

[0019] According to some embodiments of the present utility model, the annular mounting member is mounted on the carrier and is connected to the water inlet pipe.

[0020] According to some embodiments of the present utility model, the clamping arm assembly is symmetrically mounted in the annular mounting member;

[0021] The clamping arm assembly includes a clamping member and an elastic member;

[0022] One end of the clamping member is rotatably connected in the annular mounting member;

[0023] One end of the elastic member is mounted on the inner wall of the annular mounting member, and the other end of the elastic member is fixedly connected to the clamping member.

[0024] According to some embodiments of the present utility model, a part of the clamping member is located inside the annular mounting member, and the other part extends out of the annular mounting member.

[0025] According to some embodiments of the present utility model, the fastening assembly includes a rotating member and an annular fastener.

[0026] According to some embodiments of the present utility model, the rotating member is threadedly connected to the top of the annular mounting member.

[0027] According to some embodiments of the present utility model, the annular fastener is mounted on the rotating member, and the annular fastener is used to squeeze the two clamping members.

[0028] The fixture structure provided by the above technical solution has the following beneficial effects:

[0029] 1. By arranging a cleaning pipeline inside the fixture, the liquid impacts outward from the inside of the fixture, thus forming an effect similar to a fountain. Due to the existence of this pressure, debris basically will not enter the inside of the fixture. Even if some debris falls around or inside the fixture, it will be immediately washed away under the drive of this impact force. Compared with the traditional fixture cleaning structure, the cleaning effect is greatly improved, ensuring the accuracy and mechanical performance of the fixture.

[0030] 2. The liquid impacts from bottom to top, not only utilizing the impact force of the liquid, but also utilizing the buoyancy and viscous force of the liquid, making the cleaning effect better.

[0031] 3. Since the liquid impacts outwards from the inside of the fixture, there is constantly new liquid flushing the workpiece. Compared with the liquid flowing down from the outside, it will produce a better cooling effect on the workpiece, further quickly cooling the drill bit.

[0032] 4. By means of the annular conical block, the water pressure can be increased, so that the debris can be conveniently discharged from the fixture structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] Combined with Figures 1 to 7 As shown, a fixture structure 200 according to an embodiment of the present utility model includes:

[0053] A carrier 100;

[0054] A fixture structure 200, which is installed on the carrier 100;

[0055] A water inlet structure 300, which is installed on the carrier 100. An inlet water pipe 110 is arranged inside the carrier 100, and the water inlet structure 300 communicates with a plurality of the fixture structures 200 through the inlet water pipe 110.

[0056] For a fixture structure of the present utility model, the carrier 100 is used to receive external drilling materials. The drilling materials are clamped by the fixture structure 200. During drilling, debris will penetrate into the fixture structure 200. At this time, the water inlet structure 300 is connected to an external water pump, and water is introduced into the inlet water pipe 110 through the external water pump. Finally, the water will spray out from the fixture structure 200, so as to discharge the debris entering the fixture structure 200 through the water flow. An unexpected effect is achieved through the cooperation of the inlet water pipe 110 and the fixture structure 200, and the water flow can also cool the drill bit during drilling.

[0057] It should be noted that in this application, the specific clamping structure of the fixture is not the core of this application. The clamping structure of the fixture can adopt traditional mechanical, hydraulic and other structures, and this application will not introduce them in detail.

[0058] In addition, the carrier 100 can be a separate seat structure or the bottom structure of the fixture mechanism itself. The water inlet structure 300 can be just a water pipe or a valve structure provided with a switch. The inlet water pipe 110 can be a hollow hole formed inside the carrier itself or a separately arranged water pipeline.

[0059] In one embodiment, a water outlet nozzle is arranged at the end of the pipeline, and nozzles are arranged on the nozzle;

[0060] There are at least three nozzles, which are respectively located in the middle and around the nozzle. Among them, the nozzles located around are inclined.

[0061] In this embodiment, the nozzle is used to further enhance the pressure of the externally sprayed water source, so as to better discharge the debris generated during processing. There are at least three nozzles, and there can be more than three. The peripheral nozzles are inclined, making the sprayed water columns more uniform.

[0062] It should be noted that the nozzle can be threadedly connected to the end of the pipeline or installed in other detachable ways, and no more limitations are made here.

[0063] In one embodiment, a blocking block is provided at the end of each water inlet pipe 110 communicating with the fixture structure 200 to reduce the diameter of the outlet position of the water inlet pipe and increase the liquid pressure.

[0064] In this embodiment, the water pressure can be increased by the blocking block, so that the debris can be conveniently discharged from the fixture structure 200.

[0065] In one embodiment, the blocking block is an annular tapered block 120, and the annular tapered block 120 is inclined inward.

[0066] In this embodiment, since the top diameter of the annular tapered block 120 is smaller than the bottom diameter of the annular tapered block 120, the water is squeezed, thereby increasing the discharged water pressure and being able to better flush out the debris.

[0067] In one embodiment, the blocking block is threadedly connected in the pipeline where the water inlet pipe 110 communicates with the fixture structure 200.

[0068] In this embodiment, by disassembling the nozzle, the position of the annular tapered block 120 in the pipeline can be adjusted by an external tool, so that the size of the sprayed water flow can be adjusted. This is hereby explained.

[0069] In one embodiment, the fixture structure 200 includes an annular mounting member 210, a clamping arm assembly 220, and a fastening assembly 230;

[0070] The annular mounting member 210 is mounted on the carrier and communicates with the water inlet pipe 110;

[0071] The clamping arm assembly 220 is symmetrically mounted in the annular mounting member 210;

[0072] The clamping arm assembly 220 includes a clamping member 221 and an elastic member 222;

[0073] One end of the clamping member 221 is rotatably connected in the annular mounting member 210;

[0074] One end of the elastic member 222 is mounted on the inner wall of the annular mounting member 210, and the other end of the elastic member 222 is fixedly connected to the clamping member 221;

[0075] A part of the clamping member 221 is located inside the annular mounting member 210, and the other part extends outside the annular mounting member 210.

[0076] In this embodiment, the annular mounting member 210 communicates with the water inlet pipe 110, so that water source will be discharged from the annular mounting member 210. The elastic member 222 is in a tightened state under normal circumstances. The distance between the two clamping members 221 is adjusted by the fastening assembly 230, so that the adjusted two clamping members 221 can clamp the external drilling material. When adjusting, the elastic member 222 will change from the tightened state to the stretched state.

[0077] In one embodiment, the fastening assembly 230 includes a rotating member 231 and an annular fastener 232;

[0078] The rotating member 231 is threadedly connected to the top of the annular mounting member 210;

[0079] The annular fastener 232 is mounted on the rotating member 231, and the annular fastener 232 is used to squeeze the two clamping members 221.

[0080] In this embodiment, the rotating member 231 is threadedly connected to the annular mounting member 210, so that the position of the rotating member 231 on the annular mounting member 210 can be adjusted. When the rotating member 231 is continuously adjusted, the annular fastener 232 will continuously push the two clamping members 221 tightly, so as to realize the clamping of the external drilling material. The annular fastener 232 is sleeved outside the two clamping members 221, and the bottom of the annular fastener 232 abuts against the outer walls of the two clamping members 221. Therefore, when the annular fastener 232 moves downward continuously, the two clamping members 221 will approach each other, so as to clamp the external drilling material. After clamping, drilling is carried out.

[0081] It should be noted that Figure 6 is a schematic structural diagram of the drilling material. The clamping component mainly clamps the clamped part, and drills from the drilling part. This is hereby explained.

[0082] The working principle of the present utility model:

[0083] The carrier 100 is used to receive the external drilling material, and the drilling material is clamped by the fixture structure 200. When drilling, the debris will penetrate into the fixture structure 200. At this time, the water inlet structure 300 is connected to an external water pump, and water is introduced into the water inlet pipe 110 through the external water pump. Finally, the water will be sprayed out from the fixture structure 200, so as to discharge the debris entering the fixture structure 200 through the water flow. The unexpected effect is achieved through the cooperation of the water inlet pipe 110 and the fixture structure 200, and the water flow can also cool the drill bit during drilling.

[0084] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly.
