Description

Technical Field

[0001] This invention relates to the field of machining technology, specifically to a five-axis grinding machine. Background Technology

[0002] Currently, the cutting tools used in the machining industry have been upgraded. Traditional manual machine tool tools, due to their low precision and poor quality, are gradually being phased out and increasingly replaced by CNC machine tool tools. Five-axis CNC tool grinding machines are mainly used for machining various types of cemented carbide materials. Different types and specifications of tools can be independently, completely, and automatically processed on a five-axis CNC tool grinding machine, playing an irreplaceable and vital role in the mechanical field. It is well known that five-axis grinding machines generate a large amount of waste material during machining, and this waste splashing can easily injure operators near the machine. Therefore, protective covers are needed on five-axis grinding machines. However, the presence of these covers necessitates manual loading and unloading of workpieces on existing five-axis grinding machines, which significantly reduces the machine's efficiency and increases production costs, requiring further improvement. Summary of the Invention

[0003] The technical problem of the present invention is to provide a five-axis grinding machine.

[0004] To achieve the above objectives, the present invention provides the following technical solution: including a housing, wherein a cutting structure and a clamping structure are installed inside the housing, and a loading / unloading assembly and an assembly assembly are installed at the bottom of the housing;

[0005] The loading and unloading assembly includes a base, in which a loading trough and an assembly trough are provided. A loading wheel is rotatably connected in the loading trough. The loading wheel has a storage trough and a drive shaft is coaxially fixedly connected to the loading wheel. One end of the drive shaft passes through the base and is fixedly connected at intervals to a misaligned wedge and a discharge wedge. A rotary spring is fixedly connected in the base. The rotary spring is fixedly connected to a slide rod that is slidably connected to the base. A lever that cooperates with the misaligned wedge and the discharge wedge is fixedly connected to the end of the slide rod. A feed trough and a discharge trough are provided on both sides of the bottom of the loading trough. A conveying mechanism is provided at the feed trough end, and a storage box that is slidably connected to the base is provided at the discharge trough end.

[0006] The assembly component includes a return spring fixedly connected in the assembly slot, an assembly rack slidably connected to the end of the return spring and the base, the assembly rack meshing with an assembly gear, rotating rods fixedly connected to both ends of the assembly gear, a movable rod slidably connected to the rotating rod, and an assembly spring fixedly connected between the movable rod and the rotating rod.

[0007] As a further embodiment of the present invention, the clamping structure includes a bracket slidably connected to the outer shell, a clamping seat rotatably connected to the bracket, a clamping spring rotatably connected to the clamping seat via a bearing, a clamping sleeve slidably connected to the clamping spring and the clamping seat, a clamping head slidably connected to the clamping sleeve, a limiting rod slidably connected to the rear side of the clamping head and fixedly connected to the clamping sleeve, a tension spring fixedly connected between the upper rear end of the clamping head and the clamping sleeve, a trigger plate rotatably connected to the outer end of the clamping sleeve, a trigger rod matching the trigger plate fixedly connected to the base, and a shrinking shell for shrinking the clamping head fixedly connected to the outer end of the clamping seat;

[0008] As a further embodiment of the present invention, the base is threadedly connected to a fixing plate, the fixing plate is threadedly connected to a screw, the inner end of the screw is fixedly connected to a mounting plate, and the mounting plate is fitted with a rubber sheet that abuts against the feeding wheel;

[0009] As a further embodiment of the present invention, both sides of the fixing plate are fixedly connected to connecting members, and the connecting members are threadedly connected to fastening bolts.

[0010] As a further embodiment of the present invention, the bottom of the base near the discharge trough is provided with a plug-in groove that matches the storage box;

[0011] As a further embodiment of the present invention, an inclined guide rail is provided between the base and the conveying mechanism;

[0012] As a further embodiment of the present invention, the discharge trough is inclined and its height is higher than that of the feed trough.

[0013] As a further embodiment of the present invention, the discharge wedge column includes a sleeve, and a driving part and a transverse groove are fixedly connected to the outer wall of the sleeve.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] In this invention, during the movement of the holding structure to the loading and unloading assembly, the clamping structure releases the workpiece, and the assembly assembly sends the workpiece from the clamping structure to the storage groove on the side wall of the loading wheel. The clamping structure then moves to the loading and unloading assembly, using its movement as a power source to rotate the loading wheel, which simultaneously loads and unloads the workpiece. The assembly assembly then sends the workpiece back into the clamping structure, which clamps the workpiece and pulls it out of the storage groove. This allows the loading and unloading of the five-axis grinding machine to be completed without the influence of the protective cover. This solves the problem that the presence of the protective cover requires manual loading and unloading of workpieces in existing five-axis grinding machines, which greatly reduces the working efficiency of the five-axis grinding machine and increases the production cost of the workpiece.

[0016] In this invention, when the clamping structure releases the workpiece, it pushes the assembly rack, which compresses the assembly spring and simultaneously drives the assembly gear to rotate. The assembly gear drives the rotating rod and the movable rod to rotate along the axis of the assembly gear. After the movable rod contacts the workpiece inserted into the storage groove, it pushes the workpiece into the storage groove. The assembly spring contracts to prevent excessive compression between the movable rod and the workpiece, which could cause deformation. When the assembly spring is released, the movable rod pushes the workpiece to move further, thereby completely sending the workpiece into the storage groove or the clamping structure. This prevents unstable workpiece clamping or obstruction of the loading wheel rotation, which would affect the loading and unloading operation of the device. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1-10 The present invention provides a technical solution: including a shell 1, a cutting structure 2 and a clamping structure 3 installed inside the shell 1, and a loading and unloading assembly 4 and an assembly assembly 6 installed at the bottom of the shell 1;

[0032] The loading and unloading assembly 4 includes a base 41, with a loading groove 42 and an assembly groove 43 inside the base 41. A loading wheel 44 is rotatably connected inside the loading groove 42. The loading wheel 44 has a storage groove 45 and a drive shaft 46 is coaxially fixedly connected to the loading wheel 44. One end of the drive shaft 46 passes through the base 41 and is fixedly connected at intervals to a misaligned wedge post 47 and a discharge wedge post 48. A rotary spring 51 is fixedly connected inside the base 41. A slide rod 52 is fixedly connected to the base 41 and is slidably connected to the base 41. A paddle 53 that cooperates with the misaligned wedge post 47 and the discharge wedge post 48 is fixedly connected to the end of the slide rod 52. A feed groove 8 and a discharge groove 9 are opened on both sides of the bottom of the loading groove 42. A conveying mechanism 10 is provided at the end of the feed groove 8, and a storage box 11 that is slidably connected to the base 41 is provided at the end of the discharge groove 9.

[0033] The assembly component 6 includes a return spring 61 fixedly connected in the assembly groove 43. An assembly rack 62 slidably connected to the base 41 is fixedly connected to the end of the return spring 61. An assembly gear 63 meshes with the assembly rack 62. Rotary rods 64 are fixedly connected to both ends of the assembly gear 63. A movable rod 65 is slidably connected to the rotating rod 64. An assembly spring 66 is fixedly connected between the movable rod 65 and the rotating rod 64.

[0034] In use, the conveying mechanism 10 feeds the workpiece to be processed from the feed trough 8 to the loading trough 42. The five-axis grinder moves to one side, causing the clamping structure 3 to approach and contact the loading / unloading assembly 4 before retracting. When the clamping structure 3 moves to the loading / unloading assembly 4, the workpiece held by the clamping structure 3 is first fed into the top storage trough 45. The clamping structure 3 releases the processed workpiece, and the assembly assembly 6 completely moves the processed workpiece into the storage trough 45 and disengages it from the clamping structure 3. The clamping structure 3 continues to move, contacting and pushing the slide bar 52. The slide bar 52 compresses the rotating spring 51, simultaneously causing the paddle 53 to disengage from the outer misaligned wedge post 47. When the paddle 53 contacts the discharge wedge post 48, the discharge wedge post 48... Driven by the transmission shaft 46, the loading wheel 44 rotates, and the workpiece at the foremost end of the loading groove 42 moves from the bottom to the top along with the storage groove 45 on the loading wheel 44. When the clamping structure 3 moves away from the loading and unloading assembly 4, the assembly assembly 6 sends the workpiece in the top storage groove 45 to the clamping structure 3. The clamping structure 3 clamps the workpiece and pulls it out of the storage groove 45. At the same time, the rotating spring 51 pushes the slide rod 52 to move, and the slide rod 52 drives the paddle 53 to move in the opposite direction. When the paddle 53 contacts the misaligned wedge post 47, the misaligned wedge post 47 drives the discharge wedge post 48 to rotate slightly through the transmission shaft 46. Repeating the above operation can realize automatic loading and unloading without manual loading and unloading, thereby improving the processing efficiency of the five-axis grinding machine.

[0035] When the clamping structure 3 releases the workpiece, it pushes the assembly rack 62, which compresses the assembly spring 66 and simultaneously drives the assembly gear 63 to rotate. The assembly gear 63 drives the rotating rod 64 and the movable rod 65 to rotate along the axis of the assembly gear 63. After the movable rod 65 contacts the workpiece inserted into the storage groove 45, it pushes the workpiece into the storage groove 45. The assembly spring 66 contracts to prevent the movable rod 65 from being excessively squeezed against the workpiece, which could cause deformation. When the assembly spring 66 is released, the movable rod 65 pushes the workpiece to move further, thereby completely feeding the workpiece into the storage groove 45 or the clamping structure 3. This prevents the workpiece from being clamped unstable or from obstructing the rotation of the loading wheel 44, which would affect the loading and unloading operation of the device.

[0036] In summary, during the movement of the clamping structure 3 to the loading / unloading assembly 4, the clamping structure 3 releases the workpiece, and the assembly assembly 6 delivers the workpiece from the clamping structure 3 to the storage groove 45 on the side wall of the loading wheel 44. The clamping structure 3 then moves to the loading / unloading assembly 4, using the movement of the clamping structure 3 as a power source to rotate the loading wheel 44, which simultaneously performs loading and unloading. The assembly assembly 6 then delivers the workpiece back into the clamping structure 3, which clamps the workpiece and pulls it out of the storage groove 45. This allows the loading and unloading of the five-axis grinding machine to be completed without the influence of the protective cover, solving the problem that the presence of the protective cover requires manual loading and unloading of workpieces in existing five-axis grinding machines, which greatly reduces the working efficiency of the five-axis grinding machine and increases the production cost of the workpiece.

[0037] As a further embodiment of the present invention, the clamping structure 3 includes a bracket 31 slidably connected to the outer shell 1, a clamping seat 32 rotatably connected to the bracket 31, a clamping spring 33 rotatably connected to the clamping seat 32 via a bearing, a clamping sleeve 34 slidably connected to the clamping spring 33 and the clamping seat 32, a clamping head 35 slidably connected to the clamping sleeve 34, a limiting rod 36 slidably connected to the rear side of the clamping head 35 and fixedly connected to the clamping sleeve 34, a tension spring 37 fixedly connected between the upper rear end of the clamping head 35 and the clamping sleeve 34, a trigger plate 38 rotatably connected to the outer end of the clamping sleeve 34, a trigger rod 39 matching the trigger plate 38 fixedly connected to the base 41, and a shrinking shell 30 for shrinking the clamping head 35 fixedly connected to the outer end of the clamping seat 32.

[0038] In use, when the trigger plate 38 contacts the trigger rod 39, the trigger plate 38 continues to move, and the clamping sleeve 34, which is rotatably connected to it, stops moving and compresses the clamping spring 33. The clamping head 35, which is slidably connected to the clamping sleeve 34, and the shrinking shell 30 are displaced. Under the action of the clamping tension spring 37, the clamping head 35 moves around along the limiting rod 36. The workpiece between the clamping heads 35 is released from the clamping structure 3, and vice versa, the workpiece is clamped, realizing automatic clamping and releasing of the workpiece, thereby improving the automation level of the device. It should be noted that at this time, the inner end of the workpiece is located in the storage groove 45. In addition, the trigger plate 38 and the clamping sleeve 34 are rotatably set to avoid the trigger plate 38 and the clamping sleeve 34 rotating together, which would cause the trigger plate 38 and the trigger rod 39 to be misaligned, and the trigger rod 39 would not be able to abut against the trigger plate 38.

[0039] As a further embodiment of the present invention, the base 41 is threadedly connected to a fixing plate 7, the fixing plate 7 is threadedly connected to a screw 71, the inner end of the screw 71 is fixedly connected to a mounting plate 72, and the mounting plate 72 is fitted with a rubber sheet 73 that abuts against the feeding wheel 44.

[0040] In use, the contact between the rubber sheet 73 and the feeding wheel 44 increases the resistance encountered when the feeding wheel 44 rotates, preventing the feeding wheel 44 from rotating without external force, which would prevent the processed workpiece from being inserted into the storage groove 45. In addition, the threaded connection between the fixing plate 7 and the base 41 allows for easy separation of the fixing plate 7 and the base 41, thus facilitating the replacement of the rubber sheet 73. The screw 71 can adjust the position of the mounting plate 72, changing the compressive force on the rubber sheet 73, preventing excessive wear of the rubber sheet 73, and also preventing the rubber sheet 73 from becoming thinner, which would reduce the friction of the feeding wheel 44.

[0041] As a further embodiment of the present invention, both sides of the fixing plate 7 are fixedly connected to the connecting member 74, and the connecting member 74 is threadedly connected to the fastening bolt 75;

[0042] In use, after the fixing plate 7 is threadedly connected to the base 41, rotating the fastening bolt 75 can make the threads between the fixing plate 7 and the base 41 fit together, preventing the fixing plate 7 from rotating relative to the base 41, which would cause the fixing plate 7 to fall off and cause the feeding wheel 44 to rotate. This further prevents the feeding wheel 44 from rotating without external force, thus preventing the processed workpiece from being inserted into the storage groove 45.

[0043] As a further embodiment of the present invention, the bottom of the base 41 near the discharge trough 9 is provided with a plug-in groove 76 that matches the storage box 11.

[0044] When in use, the insertion slot 76 can retract the inner end of the storage box 11 into the base 41, thereby ensuring that the workpiece falling from the discharge slot 9 can enter the storage box 11, preventing the workpiece from falling outside the storage box 11 and increasing the difficulty of retrieving the workpiece.

[0045] As a further embodiment of the present invention, an inclined guide rail 12 is provided between the base 41 and the conveying mechanism 10;

[0046] In use, the inclined guide rail 12 can guide the workpiece. After the foremost workpiece is removed, the remaining workpieces can move along the guide rail 12 under the action of gravity and fill in the gaps by gravity.

[0047] As a further embodiment of the present invention, the discharge trough 9 is inclined and its height is higher than that of the feeding trough 42;

[0048] In use, the inclined setting of the discharge chute 9 can guide the processed workpiece. When the processed workpiece moves to the discharge chute 9, the workpiece falls into the storage box 11 along the discharge chute 9 under the action of gravity. The workpiece is unloaded by gravity itself, which not only prevents the workpiece from continuing to rotate with the feeding wheel 44, but also completes the unloading without external power.

[0049] As a further embodiment of the present invention, the discharge wedge column 48 includes a sleeve, and a driving part and a transverse groove are fixedly connected to the outer wall of the sleeve.

[0050] When in use, when the paddle 53 contacts the drive unit, the feed wheel 44 rotates, and the paddle 5...

[0051] When contacting the transverse groove, the feeding wheel 44 does not rotate.
