Description

Technical Field

[0001] The utility model relates to the field of machine tool chip removal, in particular to a drawer-type chip removal mechanism for machine tools. Background Art

[0002] Machine tool chip removal refers to the process of automatically transporting metal chips, shavings and other waste materials generated by cutting to a designated location during the processing of CNC machine tools, modular machine tools, assembly lines, automatic lines, etc. The machine tool chip removal mechanism is the key equipment to achieve this process. They use different working principles and structural forms to effectively collect and process these waste materials, thereby keeping the processing environment clean and improving production efficiency.

[0003] Traditional machine tools use a drawer-type chip removal mechanism. When collecting waste chips, the machine tool turning tool will turn out long waste wires. The long waste wires will become tangled and blocked, causing the discharge port to be blocked, making it impossible for the waste to fall for transportation, thus affecting the work process and causing unnecessary economic losses. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a drawer-type chip removal mechanism for machine tools, which can hook, pull and cut the falling metal waste wires with longer lengths, so that the metal waste wires are crushed into smaller-sized waste chips, which is conducive to better collection and recycling.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a drawer-type chip removal mechanism for machine tools, comprising a chip storage bin, a collection drawer and a fixed block, two groups of slide grooves are provided inside the chip storage bin, and a collection drawer is provided inside the chip storage bin, two groups of sliders are fixed on both sides of the collection drawer, and are slidably engaged with the slide grooves, several groups of feeding grilles are provided on the top of the chip storage bin, and three groups of rotating rods are rotatably connected to the inside of the chip storage bin, and several groups of crushing knives are provided on the outside of the three groups of rotating rods.

[0006] By adopting the above technical solution, the feed grid is located at the top of the debris storage bin, which is used for waste to fall into the interior of the debris storage bin. The chutes are located on both sides of the interior of the debris storage bin, which are used to guide the two sets of sliders on both sides of the collection drawer to slide. Several groups of crushing knives are respectively installed on the outside of the three groups of rotating rods, which cut, hook and crush the waste as the rotating rods rotate.

[0007] Furthermore, a baffle is fixed on the front surface of the collection drawer, and a handle is fixed on the front surface of the baffle, a fixed block is fixed on the front surface of the debris storage bin, and a baffle is slidably provided inside the fixed block, a pull block is fixed on the top of the baffle, and two groups of push plates are fixed on both sides of the baffle, two groups of fixed columns are fixed inside the fixed block, and are slidably connected to the push plates, and a spring is sleeved on the outer side of the fixed column.

[0008] By adopting the above technical solution, a baffle is fixed on the front surface of the collection drawer, which not only prevents debris from falling out of the front end of the drawer, but also increases the overall structural strength of the drawer. The handle fixed on the front surface of the baffle provides convenience for the operator, making it easier and faster to pull out and push in the drawer. Through the baffle sliding inside the fixed block and the pull block fixed on the top of the baffle, the operator can easily pull the pull block to move the baffle, thereby controlling the opening and closing of the baffle.

[0009] Furthermore, the top of the spring is fixedly connected to the fixed block, and the bottom of the spring is tightly pressed against the push piece.

[0010] By adopting the above technical solution, the top of the spring is fixedly connected to the fixed block, providing it with a firm support point, ensuring that the spring will not shake or shift during operation. At the same time, the bottom of the spring is tightly pressed against the push piece, so that the elastic force of the spring can directly act on the push piece, providing it with stable rebound force.

[0011] Furthermore, the plurality of groups of crushing knives are installed inside the plurality of groups of feeding grilles, and the outer ends of the plurality of groups of crushing knives are provided with a plurality of groups of hook-shaped structures.

[0012] By adopting the above technical solution, the crushing knife is installed inside the feed grille, so that the waste chips can be immediately cut and hooked by the crushing knife when passing through the feed grille. The hook-shaped structure opened at the outer end of the crushing knife further enhances its crushing effect.

[0013] Furthermore, a first driving wheel is fixed to the rear end of a group of rotating rods, and a second driving wheel is fixed to the back of the first driving wheel. A driving motor is provided on the back of the debris storage bin, and the output end of the driving motor is connected to the back of the second driving wheel.

[0014] By adopting the above technical solution, a compact and efficient driving structure is formed by fixing the first driving wheel to the rear end of a set of rotating rods and fixing the second driving wheel to the back of the first driving wheel.

[0015] Furthermore, a second transmission belt is sleeved on the outer side of the second driving wheel, and a first transmission belt is sleeved on the outer side of the first driving wheel.

[0016] By adopting the above technical solution, the second transmission belt sleeved on the outer side of the second driving wheel and the first transmission belt sleeved on the outer side of the first driving wheel can simultaneously drive the first transmission belt and the second transmission belt to perform synchronous transmission when the second driving wheel rotates.

[0017] Furthermore, a second driven wheel is fixed to the rear end of one group of rotating rods and is sleeved with the other end of the second transmission belt. A first driven wheel is fixed to the rear end of one group of rotating rods and is sleeved with the other end of the first transmission belt.

[0018] By adopting the above technical solution, a complete transmission chain is formed by fixing the second driven wheel at the rear end of a set of rotating rods and socketing it with the other end of the second transmission belt, and fixing the first driven wheel at the rear end of another set of rotating rods and socketing it with the other end of the first transmission belt.

[0019] In summary, the present invention has the following beneficial effects:

[0020] 1. The utility model is provided with a feed grid, a rotating rod and a crushing knife. When the rotating rod is driven by a driving motor to drive the crushing knife on its outer side to rotate in the feed grid opened on the top of the debris storage bin, the debris falling on the top of the feed grid will be discharged into the collection drawer inside the debris storage bin. When it comes to long waste chips, the crushing knife will cut and crush them, and use the claw structure at its outer end to hook the debris into the interior of the debris storage bin, thereby preventing the long waste chips from clogging the feed grid and affecting the operation process.

[0021] 2. The utility model provides a blocking function for the baffle by setting a blocking piece, preventing the collection drawer from sliding out of the debris storage bin during operation. At the same time, pulling the pull block upward can release the blocking piece from blocking the baffle. In the process of the blocking piece driving the push piece to move upward through the rise of the pull block, the push piece will compress the spring on the outside of the fixed column, so that after releasing the pull block, the spring will provide a rebound function for the push piece to make the blocking piece rebound synchronously.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] The following describes an embodiment of the present invention based on its overall structure.

[0032] In this embodiment:

[0033] A drawer-type chip removal mechanism for machine tools, such as Figure 1-Figure 5As shown, it includes a debris storage bin 1, a collection drawer 4 and a fixed block 8. Two groups of chutes 3 are opened inside the debris storage bin 1, and a collection drawer 4 is set inside the debris storage bin 1. Two groups of sliders 5 are fixed on both sides of the collection drawer 4 and slide and engage with the chutes 3. Several groups of feeding grilles 2 are opened on the top of the debris storage bin 1, and three groups of rotating rods 14 are rotatably connected to the inside of the debris storage bin 1, and several groups of crushing knives 15 are set on the outside of the three groups of rotating rods 14.

[0034] Among them, the debris can directly fall into the debris storage bin 1 through the feeding grille 2 on the top of the debris storage bin 1. At the same time, the three sets of rotating rods 14 and the crushing knives 15 on their outer sides will cut, hook, pull and crush the fallen waste chips to ensure that the debris is effectively processed and its volume is reduced, which is convenient for subsequent storage and recycling. The crushed debris will fall into the collection drawer 4. When the collection drawer 4 is full, the operator can easily use the handle 7 to pull the collection drawer 4 out of the slide 3 in the debris storage bin 1 through the two sets of sliders 5.

[0035] See Figure 1 and Figure 4 , a baffle 6 is fixed to the front surface of the collection drawer 4, and a handle 7 is fixed to the front surface of the baffle 6, a fixed block 8 is fixed to the front surface of the debris storage bin 1, and a baffle 9 is slidably provided inside the fixed block 8, a pull block 10 is fixed to the top of the baffle 9, and two groups of push pieces 11 are fixed on both sides of the baffle 9, two groups of fixed columns 12 are fixed inside the fixed block 8, and are slidably connected to the push pieces 11, and a spring 13 is sleeved on the outer side of the fixed column 12;

[0036] When the collection drawer 4 needs to be pulled out, it is only necessary to pull the pull block 10 upwards so that the blocking piece 9 releases the resistance limit on the baffle 6. After releasing the pull block 10, the spring 13 will provide a rebound function to the push piece 11, so that the blocking piece 9 will automatically rebound and continue to provide the resistance limit function for the baffle 6, ensuring the stability and sealing of the collection drawer 4 in the closed state.

[0037] See Figure 1 and Figure 4 , the top of the spring 13 is fixedly connected to the fixed block 8, and the bottom of the spring 13 is tightly against the push piece 11;

[0038] Among them, the blocking and limiting effect of the blocking piece 9 on the baffle 6 is enhanced. When the blocking piece 9 drives the push piece 11 to move upward through the rise of the pull block 10, the spring 13 will be compressed and store energy. When the pull block 10 is released, the spring 13 will release the stored energy, pushing the push piece 11 and the blocking piece 9 to rebound downward, so that the blocking piece 9 continues to provide the blocking and limiting function for the baffle 6.

[0039] See Figure 1 、 Figure 2 and Figure 3, several groups of crushing knives 15 are installed inside several groups of feeding grids 2, and several groups of hook-shaped structures are opened at the outer ends of several groups of crushing knives 15;

[0040] Among them, the crushing knife 15 is installed inside the feeding grille 2, so that the waste chips can be immediately cut and hooked by the crushing knife 15 when passing through the feeding grille 2, thereby improving the processing efficiency of the debris. The hook-shaped structure can more effectively hook and cut the waste chips, and even some longer or more difficult to handle waste chips can be effectively crushed.

[0041] See Figure 2 and Figure 5 A first driving wheel 16 is fixed to the rear end of a set of rotating rods 14, and a second driving wheel 17 is fixed to the back of the first driving wheel 16. A driving motor 18 is provided on the back of the debris storage bin 1, and the output end of the driving motor 18 is connected to the back of the second driving wheel 17;

[0042] When the driving motor 18 is started, its output end is connected to the back of the second driving wheel 17 , thereby directly driving the first driving wheel 16 and the rotating rod 14 to rotate.

[0043] See Figure 2 and Figure 5 The outer side of the second driving wheel 17 is sleeved with a second transmission belt 21, and the outer side of the first driving wheel 16 is sleeved with a first transmission belt 19;

[0044] Among them, the second transmission belt 21 connected to the outside of the second driving wheel 17 and the first transmission belt 19 connected to the outside of the first driving wheel 16 can simultaneously drive the first transmission belt 19 and the second transmission belt 21 to perform synchronous transmission when the second driving wheel 17 rotates, so that the three groups of rotating rods 14 are separated by a certain distance, and effective power transmission can be achieved, ensuring that all rotating rods 14 can rotate synchronously.

[0045] See Figure 2 and Figure 5 A second driven wheel 22 is fixed to the rear end of one set of rotating rods 14 and is sleeved with the other end of the second transmission belt 21; a first driven wheel 20 is fixed to the rear end of one set of rotating rods 14 and is sleeved with the other end of the first transmission belt 19;

[0046] Among them, the power of the driving motor 18 can rotate the second driven wheel 22 and a group of rotating rods 14 fixedly connected to it through the second driving wheel 17 through the second transmission belt 21, and the first driving wheel 16 can rotate the first driven wheel 20 and a group of rotating rods 14 fixedly connected to it through the first transmission belt 19 to ensure that they can rotate synchronously.

[0047] The implementation principle of this utility model is:

[0048] First, connect the chip storage bin 1 with the machine tool discharge port for chip discharge required by the outside world, and fix the connection with the existing bolts, so that the feeding grille 2 on the top of the chip storage bin 1 is adapted to correspond to the discharge port, and then turn on the drive motor 18 through the control center to drive the second driving wheel 17 to rotate. Since the second driving wheel 17, the first driving wheel 16 and a group of rotating rods 14 form an integrated mechanism, when the second driving wheel 17 rotates, the first driving wheel 16 and a group of rotating rods 14 will rotate synchronously, and the second driving wheel 17 will drive the second driving wheel 17 through the second transmission belt 21 sleeved on the outside. The driven wheel 22 rotates synchronously, and the first driving wheel 16 drives the first driven wheel 20 to rotate synchronously through the first transmission belt 19 sleeved on the outside, so that the second transmission belt 21 and the first driven wheel 20 are respectively fixedly connected to form the rotating rod 14 of the integrated structure to rotate synchronously, and then the three groups of rotating rods 14 drive the crushing knives 15 on their respective outer sides to rotate, and the crushing knives 15 will cut, hook, pull and crush the longer waste chips that fall into the top of the feed grid 2, so that they fall into the interior of the debris storage bin 1, while the smaller particles of debris on the top of the debris storage bin 1 will directly pass through the feed grid 2 and fall into the interior of the debris storage bin 1;

[0049] After the garbage bag 1 is filled with garbage, the garbage bag 1 is automatically put into the garbage bag 1 by the user, and the garbage bag 1 is automatically put into the garbage bag 1 by the user, and the garbage bag 1 is automatically put into the garbage bag 1 by the user, and the garbage bag 1 is automatically put into the garbage bag 1 by the user, and the garbage bag 1 is automatically put into the garbage bag 1 by the user, and the garbage bag 1 is automatically put into the garbage bag 1 by the user,

[0050] Parts not involved in the present invention are the same as those in the prior art or can be implemented by using the prior art, and will not be described in detail here.

[0051] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
