Abstract
Description
Technical Field
[0001] This utility model relates to the field of milling cutter processing technology, specifically to a spraying device for milling cutter processing. Background Technology
[0002] A milling cutter is a rotating cutting tool with one or more cutting teeth used for milling operations. During operation, the cutting teeth sequentially and intermittently remove the excess material from the workpiece. Milling cutters are mainly used on milling machines to machine planes, steps, grooves, shaped surfaces, and cut off workpieces. In the field of milling cutter manufacturing and remanufacturing, surface coating is a key process to improve the wear resistance and corrosion resistance of the cutting tools.
[0003] Although existing spraying equipment is equipped with a rotating clamp, it lacks a dynamic spraying mechanism that is linked to the spray gun trajectory, making it difficult to achieve precise coverage. At the same time, the atomized paint generated by excessive spraying diffuses into the cavity, which not only wastes raw materials and increases subsequent cleaning costs, but also affects the quality of spraying. The clamp opening and closing is separate from the spraying process, requiring manual unlocking of the clamp after stopping the machine, which affects the continuous operation rhythm and is prone to damage to the uncured coating due to operational errors. Utility Model Content
[0004] The purpose of this invention is to provide a spraying device for milling cutter processing to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A spraying device for milling cutter machining includes a spraying chamber with a partition horizontally fixedly connected inside. A pair of movable baffles are movably installed above the partition, and a spray gun is mounted on the movable baffles. A pair of collecting nets are movably embedded in the movable baffles. Discharge grooves are provided on both sides of the partition. An abutment block is elastically connected to the bottom of the collecting net. An abutment rack that abuts against the abutment block is fixedly connected to the inner wall of the discharge groove. A rotating placement column is installed on the top of the partition between the two movable baffles. An adjusting plate is rotatably installed on the top surface of the partition outside the rotating placement column. A clamp adapted to the adjusting plate is installed on the rotating placement column. When the pair of movable baffles move outward synchronously and the abutment block disengages from the abutment rack, the adjusting plate opens the clamp.
[0007] In a preferred embodiment of this utility model, an adjustable pitch motor is installed on one side of the spraying chamber, and a bidirectional lead screw with a thread passing through a pair of movable baffles is installed on the output shaft of the adjustable pitch motor.
[0008] In a preferred embodiment of this utility model, the clamp includes a push sleeve elastically sleeved outside the rotating storage column and several clamping blocks movably inserted into the top of the rotating storage column. The top of the inner wall of the push sleeve is inclined and abuts against one end of the clamping block. A support block is fixedly connected to the bottom of the push sleeve. A groove for accommodating the support block is provided on the top of the adjusting plate.
[0009] In a preferred embodiment of this utility model, the adjusting disc is fitted with an adjusting toothed ring, and the top surface of the partition is elastically connected to a traction rack that meshes with the adjusting toothed ring. One end of the traction rack passes through a movable baffle and is fixedly connected to a stop block.
[0010] In a preferred embodiment of this utility model, a lifting chamber cover is movably embedded on the top of the spraying chamber, and a limiting groove is provided on both sides of the bottom of the lifting chamber cover. A limiting block that matches the limiting groove is elastically inserted into the inner wall of the spraying chamber. When one end of the pulling rack abuts against the limiting block, the limiting block is misaligned with the limiting groove.
[0011] In a preferred embodiment of this utility model, a drive motor is installed at the bottom of the partition, and the output shaft of the drive motor is fixedly connected to the bottom of the rotating storage column.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] In this invention, a double movable baffle linkage mechanism is used to achieve mechanical coupling between the adaptive adjustment of the spray gun position and the opening and closing of the clamp. This allows the movable baffle to adjust the distance between the spray gun and the milling cutter during translation, thereby expanding or shrinking the spraying coverage area. Simultaneously, during the movement, a collection net is used to collect excess suspended paint. Large paint particles are trapped by the collection net on the inner side of the movable baffle, while fine particles are discharged directionally along the discharge chute under the high-frequency vibration of the contact block, improving the paint recovery rate. Furthermore, when the movable baffle is translated to the corresponding position, it can drive the adjustment plate to release the clamp, thus eliminating the need for manual operation and making the operation simpler and more convenient, thereby improving the efficiency of continuous operation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0021] To facilitate understanding of this utility model, a more comprehensive description will be given below with reference to the accompanying drawings, which illustrate several embodiments of the utility model. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.
[0022] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.
[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0024] Example: Please refer to Figure 1-5The shown is a spraying device for milling cutter processing, including a spraying chamber 1. A partition 2 is horizontally fixedly connected inside the spraying chamber 1. A pair of movable baffles 3 are movably installed above the partition 2. A spray gun 31 is installed on the movable baffles 3. A pair of collecting nets 4 are movably embedded on the movable baffles 3. Discharge grooves 21 are opened on both sides of the partition 2. An abutting block 41 is elastically connected to the bottom of the collecting net 4. An abutting rack 22 that abuts and cooperates with the abutting block 41 is fixedly connected to the inner wall of the discharge groove 21. A rotating placement column 5 is installed between the two movable baffles 3 at the top of the partition 2. When the pair of movable baffles 3 are driven to retract inward, the distance between the spray gun 31 and the milling cutter gradually shortens, which is suitable for fine spraying. When it expands outward, the distance gradually increases, achieving large-area coverage. During the spraying process of the spray gun 31, the rotating placement column 5 with the milling cutter placed on top continuously rotates to ensure that the coating can be evenly adhered to the surface of the milling cutter. The detachable collecting net 4 is installed on the movable baffles 3 to intercept suspended coating.
[0025] When the movable baffle 3 moves outward, the abutting block 41 and the abutting rack 22 continue to abut, causing the abutting block 41 to reciprocate and vibrate the collecting net 4, causing the collected paint to fall off the collecting net 4 and into the bottom of the spraying chamber 1 for recycling, thus preventing the mesh of the collecting net 4 from clogging too quickly. An adjusting plate 23 is rotatably installed on the top surface of the partition 2 outside the rotating storage column 5. A clamp 6 adapted to the adjusting plate 23 is installed on the rotating storage column 5. When a pair of movable baffles 3 move outward synchronously and the abutting block 41 disengages from the abutting rack 22, the adjusting plate 23 is driven to open the clamp 6. When the movable baffle 3 moves to the outermost position, the adjusting plate 23 is driven to rotate, driving the clamp 6 to open so that the milling cutter can be automatically picked up and placed by the robotic arm. After the milling cutter is put back in, the movable baffles 3 on both sides are brought together to make the clamp 6 clamp the milling cutter again.
[0026] In this embodiment, a pitch-adjusting motor 11 is installed on one side of the spraying chamber 1. The output shaft of the pitch-adjusting motor 11 is equipped with a bidirectional lead screw 12 that threads through a pair of movable baffles 3. The two ends of the bidirectional lead screw 12 are respectively machined with threads in opposite directions. A limiting rod that horizontally penetrates the movable baffles 3 is also installed inside the spraying chamber 1 to ensure the stability of the movable baffles 3 when they move horizontally. The pitch-adjusting motor 11 drives the pair of movable baffles 3 to move symmetrically through the forward and reverse rotation of the bidirectional lead screw 12, so as to achieve precise adjustment of the distance between the spray gun 31 and the milling cutter. When moving inward, the spray gun 31 focuses on spraying, and when moving outward, it expands the coverage area.
[0027] In this embodiment, the clamp 6 includes a push sleeve 61 elastically sleeved outside the rotating storage column 5 and several clamping blocks 62 movably inserted into the top of the rotating storage column 5. The top of the inner wall of the push sleeve 61 is inclined and abuts against one end of the clamping block 62. A compression spring 64 is installed inside the push sleeve 61. The top of the compression spring 64 is fixed to the rotating storage column 5. A support block 63 is fixedly connected to the bottom of the push sleeve 61. The top of the adjusting plate 23 has a groove 24 for accommodating the support block 63. When a pair of movable During the stroke of the baffles 3 approaching each other, the support block 63 is outside the groove 24 and the two are offset from each other. At this time, the height of the push sleeve 61 can press against each clamping block 62, forcing each clamping block 62 to cooperate in clamping the milling cutter. When the movable baffle 3 moves out to the corresponding position, if the support block 63 enters the groove 24, the push sleeve 61 will descend rapidly under the force of the compression spring 64, causing the clamping block 62 to release the milling cutter, so as to achieve the purpose of not needing to manually adjust the fixture 6, making the spraying operation more convenient.
[0028] In this embodiment, an adjusting gear ring 25 is fitted over the adjusting disc 23. A pulling rack 26, which meshes with the adjusting gear ring 25, is elastically connected to the top surface of the partition 2. One end of the pulling rack 26 passes through the movable baffle 3 and is fixedly connected to a stop block 27. A return spring 29 is installed between the other end of the pulling rack 26 and the partition 2. When the movable baffle 3 moves outward, the pulling stop block 27 drives the pulling rack 26 to move linearly. Through meshing with the adjusting gear ring 25, the linear motion is converted into the rotation of the adjusting disc 23. When the adjusting disc 23 rotates, the wedge-shaped groove 24 on its top turns towards the support block 63 of the push sleeve 61. After the support block 63 enters the groove 24, the push sleeve 61 releases the clamping block 62, allowing the clamp 6 to release the milling cutter. When the movable baffle 3 moves inward to reset, the pull rack 26 moves in the opposite direction under the action of the reset spring 29, causing the adjusting disc 23 to rotate so that the groove 24 and the support block 63 are misaligned. This causes the push sleeve 61 to move upward and press against the clamping block 62, forcing each clamping block 62 to retract synchronously to complete the clamping of the milling cutter.
[0029] In this embodiment, a lifting chamber cover 7 is movably embedded in the top of the spraying chamber 1. Limiting grooves 71 are formed on both sides of the bottom of the lifting chamber cover 7. The limiting grooves 71 are T-shaped. A limiting block 13, adapted to the limiting groove 71, is elastically inserted into the inner wall of the spraying chamber 1. When one end of the pulling rack 26 abuts against the limiting block 13, the limiting block 13 is displaced from the limiting groove 71. When the movable baffle 3 moves outward to the corresponding position, the pulling rack 26 slides synchronously, and its end contacts the limiting block 13. Then, the pushing continues... The movable limit block 13 disengages from the limit groove 71, putting the lifting cover 7 in the unlocked state. At this time, the operator can lift the cover to load and unload the milling cutter. When the movable baffle 3 returns to its original position and moves inward, it pulls the rack 26 to move in the opposite direction. Under the elastic force, the limit block 13 re-inserts into the limit groove 71, realizing automatic locking of the cover. This linkage design ensures that the cover is forcibly locked during the spraying operation to prevent paint leakage. At the same time, during the loading and unloading stage, the cover can only be opened when the clamp 6 is loose, improving the efficiency of operation.
[0030] In this embodiment, a drive motor 28 is installed at the bottom of the partition 2. The output shaft of the drive motor 28 is fixedly connected to the bottom of the rotating storage column 5. When the drive motor 28 drives the rotating storage column 5 to rotate, the adjustment disk 23 can rotate independently. Since it meshes with the pull rack 26, it can avoid interfering with the rotating storage column 5, allowing the milling cutter to be sprayed while rotating at a uniform speed, ensuring the comprehensive coverage of the coating.
[0031] Working principle: During processing, the milling cutter is first fixed on the rotating support column 5. Then, a pair of movable baffles 3 are driven to retract inward or expand outward. When the movable baffles 3 retract inward, the distance between the spray gun 31 and the milling cutter gradually shortens, which is suitable for fine spraying. When expanding outward, the distance gradually increases, achieving large-area coverage. During the spraying process of the spray gun 31, the rotating support column 5, on top of which the milling cutter is placed, continues to rotate to ensure that the coating can be evenly adhered to the surface of the milling cutter. The detachable trapping net 4 is installed on the movable baffles 3 to intercept suspended paint. When the movable baffles 3 move outward, the abutment block 41 and the abutment teeth... The continuous contact of the strip 22 causes the abutment block 41 to reciprocate, which in turn causes the collecting net 4 to vibrate, allowing the collected paint to fall off the collecting net 4 and into the bottom of the spraying chamber 1 for recycling, thus preventing the mesh of the collecting net 4 from clogging too quickly. When a pair of movable baffles 3 move outwards in sync and the abutment block 41 disengages from the abutment rack 22, the adjusting plate 23 is driven to open the clamp 6. When the movable baffle 3 moves to the outermost position, the adjusting plate 23 is driven to rotate, which drives the clamp 6 to open so that the milling cutter can be automatically picked up and placed by the robotic arm. After the milling cutter is put back in, the movable baffles 3 on both sides are brought together to make the clamp 6 clamp the milling cutter again.
[0032] 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.
