Description

Technical Field

[0001] This utility model relates to the field of chip removal technology for water nozzle-type workpieces, and specifically to an automatic chip removal machine. Background Technology

[0002] In modern manufacturing, the machining accuracy and surface quality of water tap-like parts are crucial due to their wide range of applications and specific functional requirements. The use of cutting fluid is indispensable during the machining process of these parts; it helps cool the cutting tools, reduce friction, and remove chips, thereby ensuring smooth machining and workpiece quality. However, after machining, a large amount of cutting fluid and machining debris often remain on the inner and outer walls of the workpiece. These residues not only affect the subsequent assembly accuracy and performance of the workpiece but may also cause scratches between workpieces during stacking, leading to defects such as white spots and scratches on the workpiece surface, severely damaging the final appearance quality of the workpiece.

[0003] To address this issue, the traditional approach involves workshop workers using high-pressure air guns to individually blow away cutting fluid and debris from the surface and inner holes of each workpiece. While this manual operation is simple and easy to perform, it suffers from significant efficiency bottlenecks. First, the individual blowing method greatly limits the overall capacity of the production line, especially in high-volume, continuous production scenarios, where the inefficiency of manual operation becomes a key factor restricting production efficiency. Second, the blown workpieces still require manual unloading, further increasing labor and time costs. Furthermore, inconsistencies in manual operation can lead to inconsistent cleaning results, affecting the uniformity of the final product.

[0004] In view of the above problems, it is necessary to develop an automatic chip blower that can automatically complete the chip blowing operation of the workpiece, improve production efficiency, and ensure the consistency and stability of cleaning quality. Utility Model Content

[0009] frame;

[0010] The workpiece fixture is mounted on the machine frame and has at least two spaced positioning holes for positioning the workpiece and ensuring that the axis of the workpiece is vertical.

[0017] A moving mechanism is mounted on the frame and is connected to the lifting mechanism via a transmission. The lifting mechanism is slidably mounted on the frame along a first direction, which is the orientation of the opening of the limiting recess. The moving mechanism is used to drive the lifting mechanism to slide.

[0018] Furthermore, the aforementioned automatic chip blower also includes a material tray with several rows of workpiece receiving slots. The number of workpiece receiving slots in each row is the same as the number of positioning holes on the mounting plate, and they correspond one-to-one.

[0026] 1. When using the automatic chip blowing machine provided by this utility model, firstly, the workpieces are positioned one by one at the positioning holes of the workpiece fixture; then, air is blown from the air outlet, and at the same time, the lifting mechanism drives the air outlet to move up and down reciprocally relative to the positioning holes to blow air up and down on each workpiece; after the air blowing cleaning is completed, the air outlet stops blowing air, and at the same time, the lifting mechanism drives the air outlet to rise so that the workpiece can be unloaded.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] This utility model provides an automatic chip blowing machine to solve the problem of how to automatically blow chips off water nozzle-type workpieces 8 and improve production efficiency.

[0042] See Figure 1 and Figure 2 As shown, Figure 1 This is a perspective view of the automatic chip blower in the embodiment. Figure 2 for Figure 1 The enlarged schematic diagram at point A shows that the automatic chip blowing machine includes a frame 1, a workpiece fixture 2, an air blowing mechanism 3, and a lifting mechanism 4.

[0043] The workpiece fixture 2 is mounted on the frame 1, and the workpiece fixture 2 has at least two spaced positioning holes 221. The positioning holes 221 are used to position the workpiece 8 and to make the axis of the workpiece 8 vertical.

[0044] The air blowing mechanism 3 includes an air outlet 31 for communicating with an air source. The air outlet 31 is installed on the output end of the lifting mechanism 4 by welding or screwing. The number of air outlets 31 is the same as the number of positioning holes 221, and they are arranged in a one-to-one correspondence. The lifting mechanism 4 is mounted on the frame 1 and is used to drive the air outlets 31 to reciprocate up and down relative to the positioning holes 221 to blow air up and down on the corresponding workpiece 8.

[0045] When using the automatic chip blowing machine of the above technical solution, firstly, the workpieces 8 are positioned one by one at each positioning hole 221 of the workpiece fixture 2; then, the air outlet 31 blows air, and at the same time, the lifting mechanism 4 drives the air outlet 31 to move up and down relative to the positioning hole 221 to blow air up and down on each workpiece 8; after the air blowing cleaning is completed, the air outlet 31 stops blowing air, and at the same time, the lifting mechanism 4 drives the air outlet 31 to rise so as to unload the workpieces 8.

[0046] As can be seen from the above usage process, compared with the prior art, the present invention has the following advantages:

[0047] 1) This utility model can automatically blow away debris from water nozzle-type workpieces 8 by combining the air blowing mechanism 3 and the lifting mechanism 4, replacing manual labor, effectively improving production efficiency, reducing labor costs, and ensuring the consistency and stability of cleaning quality.

[0048] 2) The air blowing mechanism 3 and the lifting mechanism 4 work together to blow air up and down on the workpiece 8. This up and down blowing method can improve the cleaning effect and effectively remove cutting fluid and debris from the surface and inner hole of the workpiece 8.

[0049] 3) The air blowing mechanism 3 can perform one-to-one air blowing cleaning on the workpiece 8 through the air outlet 31, ensuring that each workpiece 8 can be cleaned evenly and effectively, and ensuring the consistency and stability of cleaning quality.

[0050] See Figure 3 As shown, Figure 3 This is a schematic diagram of the workpiece fixture, air blowing mechanism, and lifting mechanism in one embodiment. In one implementation of the workpiece fixture 2, the workpiece fixture 2 includes a fixed base 21, a mounting plate 22, and positioning elements 23. The fixed base 21 is fixed to the frame 1 by screwing or welding. There are two fixed bases 21, each with a limiting recess 211. The two ends of the mounting plate 22 are respectively fitted with the two limiting recesses 211, and the mounting plate 22 has at least two positioning holes 221 and threaded holes 222 communicating with the positioning holes 221. The positioning holes 221 are used for the workpiece 8 to pass through. The number of positioning elements 23 is the same as the number of threaded holes 222. The positioning elements 23 are screwed into the threaded holes 222 of the mounting plate 22 to press the workpiece 8 tightly against the positioning holes 221. Thus, the fixed base 21 can limit the position of the mounting plate 22 through the limiting recess 211, while the positioning member 23 can fix the workpiece 8 and the mounting plate 22, thereby achieving the positioning of the workpiece 8 and ensuring the stability and accuracy of the workpiece 8 during the air blowing process. Furthermore, the mounting plate 22 is detachably connected to the fixed base 21 by a plug-in connection, which facilitates the quick replacement of mounting plates 22 with different sized positioning holes 221 according to different sizes of the workpiece 8, adapting to diverse production needs and improving the applicability of the workpiece fixture 2.

[0051] The aforementioned positioning component 23 can be any existing threaded rod such as a screw or threaded rod. The aforementioned air source can be any existing air supply equipment.

[0052] See Figure 1 and Figure 3As shown, based on the above embodiment, the automatic chip blowing machine further includes a clamping mechanism 5 and a moving mechanism 6. The clamping mechanism 5 is installed on the output end of the lifting mechanism 4 and is used to clamp or release the workpiece fixture 2, or to clamp or release the workpiece 8 on the workpiece fixture 2. The moving mechanism 6 is mounted on the frame 1 by means of screwing or welding, and is connected to the lifting mechanism 4 in a transmission manner. The lifting mechanism 4 is slidably connected to the frame 1 along a first direction, which is the orientation of the opening of the limiting recess 211. The moving mechanism 6 is used to drive the lifting mechanism 4 to slide. In this way, the clamping mechanism 5 and the moving mechanism 6 cooperate to drive the mounting plate 22 to move along the first direction, thereby disengaging it from the limiting recess 211. Combined with the lifting mechanism 4, this can drive the mounting plate 22 and several workpieces 8 on the mounting plate 22 away from the fixed seat 21, realizing automatic unloading of the workpieces 8.

[0053] The aforementioned lifting mechanism 4 can use existing telescopic displacement drive mechanisms such as telescopic cylinders or telescopic poles, or linear displacement drive mechanisms such as servo motors, stepper motors-lead screws and nuts, or linear motors and linear modules. The latter implementation enables precise control and rapid response of the lifting action, facilitating the transfer of the workpiece 8 and improving the stability and reliability of the equipment. The aforementioned moving mechanism 6 can also use linear displacement drive mechanisms such as servo motors, stepper motors-lead screws and nuts, or linear motors and linear modules, with its output end connected to the lifting mechanism 4 via welding or screwing.

[0054] See Figure 1 and Figure 3 As shown, in one embodiment of the clamping mechanism 5, the clamping mechanism 5 includes at least two clamping drive members 51. The clamping drive members 51 are installed on the output end of the lifting mechanism 4 by welding or screwing, etc. The number of clamping drive members 51 is the same as the number of positioning holes 221, and they correspond one-to-one. An elastic block 32 is adhered to the output end of the clamping drive member 51, and the clamping drive member 51 clamps the workpiece 8 through the elastic block 32 to avoid damaging the surface of the workpiece 8.

[0055] The aforementioned clamping drive 51 can use an existing clamping cylinder.

[0056] Based on the embodiment of the workpiece fixture 2 described above, the automatic chip blowing machine also includes a material tray (not shown in the figure). The material tray has several rows of workpiece 8 receiving slots, and the number of workpiece 8 receiving slots in each row is the same as the number of positioning holes 221, and they correspond one-to-one. In this way, the clamping mechanism 5, the lifting mechanism 4, and the moving mechanism 6 work together to not only realize the automatic unloading of multiple workpieces 8 at one time, but also to place multiple unloaded workpieces 8 together into the same row of workpiece 8 receiving slots in the material tray, thereby realizing the automatic stacking of multiple workpieces 8 at one time.

[0057] See Figure 1 and Figure 3As shown, based on the above embodiment, the automatic chip blowing machine also includes a conveyor belt 7. The conveyor belt 7 is mounted on the frame 1 and is used to transport the workpieces 8 along a first direction. In this way, the conveyor belt 7 can conveniently and automatically feed the unloaded workpieces 8 in batches to the next process.

[0058] See Figure 4 As shown, Figure 4 The diagram shows a partial cross-sectional view of the automatic chip blower in this embodiment. Based on the aforementioned embodiment of the workpiece fixture 2, at least two workpiece fixtures 2 are spaced apart along the first direction, and at least two air blowing mechanisms 3 and clamping mechanisms 5 are correspondingly installed. In this way, workpieces 8 on the two workpiece fixtures 2 can be blown away simultaneously, and the lifting mechanism 4 and the moving mechanism 6 cooperate to simultaneously unload workpieces 8 from both workpiece fixtures 2, further improving work efficiency and facilitating mass production.

[0059] See Figure 4 As shown, based on the above embodiment, a baffle 41 is also provided on the output end of the lifting mechanism 4 by means of screwing or welding. The baffle 41 is located between the two air blowing mechanisms 3 and is used to block waste debris. This can effectively prevent the air blowing mechanism 3 from blowing the waste debris of the workpiece 8 of the corresponding workpiece fixture 2 onto the workpiece 8 of the other workpiece fixture 2.

[0060] Based on any of the above embodiments, the automatic chip blower also includes a positioning detection element (not shown in the figure). The positioning detection element is used to detect the position of the air blowing mechanism 3 in the first direction, so as to accurately control the relative position of the air outlet 31 and the positioning hole 221, ensuring that the air outlet 31 and the positioning hole 221 are in a one-to-one positional alignment, thereby ensuring the quality of chip cleaning.

[0061] The aforementioned positioning detection device can use existing infrared sensors, position sensors, or position switches. The positioning detection device can indirectly determine the relative position of the air nozzle 31 and the positioning hole 221 by detecting the position of the output end of the moving mechanism 6, or it can directly detect whether the air nozzle 31 is in position.

[0062] See Figure 4 As shown, based on any of the above embodiments, the automatic chip blower also includes a chip collection container 9 and a chip guide plate. The chip collection container 9 is placed below the workpiece fixture 2 and is used to collect cutting fluid and waste chips blown off by the air blowing mechanism 3, keeping the working area clean and hygienic. The chip guide plate (not shown in the figure) is located around the workpiece fixture 2 and is used to guide the waste chips into the chip collection container 9. In this way, the air blowing mechanism 3 blows chips vertically downwards onto the workpiece 8 on the workpiece fixture 2. During the chip blowing process, most of the waste chips can be blown into the chip collection container 9, and the remaining waste chips can be guided into the chip collection container 9 through the chip guide plate, effectively preventing some waste chips from scattering and polluting the ground. It can be seen that the chip collection container 9 and the chip guide plate work together to effectively keep the working area clean.

[0063] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
