Description

Technical Field

[0001] This utility model relates to the field of hardware processing equipment technology, and in particular to a hardware processing machine. Background Technology

[0002] The working principle of a precision machining center for hardware involves high-precision cutting, forming, or surface treatment technologies, which aim to process metal raw materials into parts that meet strict requirements for size, shape, and surface quality, so as to be suitable for precision assembly on different products.

[0003] Currently, precision machining machines for hardware parts on the market are generally divided into linear stepper type and rotary type. Linear stepper type precision machining machines use a chain as the medium and indexing cams to achieve stepping conveying action. During the chuck conveying process, processing is performed at various workstations. This type of equipment has many chucks, the chain is prone to misalignment, and the processing accuracy is relatively poor. Therefore, rotary type precision machining machines are now more commonly chosen for precision machining of hardware parts.

[0004] Regarding disc-type precision machining machines for hardware, Chinese patent CN201710525911.X discloses a disc-type multi-station pen tip processing device. However, this design suffers from the following technical defects, rendering it unsuitable for high-speed operation:

[0005] 1. For the rotation drive of the machining head, a servo motor and multi-stage pulleys are used to control the rotational speed of the rollers. In practical applications, since there is only one servo motor, although the speed of each roller can be made different through the multi-stage pulleys, it is not possible to adjust the speed of a single roller. If speed adjustment of a single roller is required, the corresponding pulley must be disassembled and replaced, which is cumbersome. In addition, the belts between the pulleys are round belts, which are prone to slippage during operation.

[0006] 2. The lifting drive for the machining head uses a motor and a cam-like rocker arm structure. The centerline of the connecting shaft is offset relative to the centerline of the output shaft. When the connecting shaft rotates with the output shaft of the first drive motor, the connecting rod moves up and down under the drive of the connecting shaft, thus driving the lifting rod to move up and down, and consequently moving the machining head up and down. However, in practical applications, this drive structure requires extremely high dimensional accuracy at the connections between various components. Even a slight error can lead to a decrease in motion accuracy. Furthermore, when the equipment operates at high speed, fatigue wear can easily occur at the connections between the various components, and vibrations can occur due to inertial forces, leading to unstable equipment operation and a reduced service life.

[0007] 3. For the rotation drive of the rotating disk (middle disk), a structure of motor + pulley + worm gear is adopted. The worm gear is linked to the output shaft of the first drive motor through a pulley assembly. The rotating disk is provided with protrusions that mesh with the worm gear, and the protrusions are distributed at intervals along the circumference of the rotating disk. The rotation of the worm gear drives the rotating disk to rotate. However, in actual application, the frequent friction between the worm gear and the worm wheel can easily lead to wear and a large amount of heat at their meshing points, resulting in transmission clearance, affecting positioning accuracy, and the worm gear is prone to elastic deformation under impact loads.

[0008] 4. Regarding the opening and closing of the chucks, a push rod is used for control. When the push rod pushes upward, the chuck opens, allowing for the loading and unloading of metal parts. The other chucks not pushed upward remain clamped to the metal parts. The upward and downward movement of the push rod employs a motor + cam-like rocker arm structure. The centerline of the connecting shaft is eccentrically positioned relative to the centerline of the output shaft. As the connecting shaft rotates with the output shaft of the first drive motor, the connecting rod moves up and down under the drive of the connecting shaft, thus driving the lifting rod to move up and down. The up and down movement of the lifting rod drives the drive rod and connecting rod to rise and fall, which in turn drives the slider connected to the connecting rod and the push rod fixed to the slider to rise and fall. However, in practical applications, this drive structure requires extremely high dimensional accuracy at the connections between various structures. Even a small error can lead to reduced motion accuracy. Furthermore, once the equipment operates at high speed, fatigue wear can easily occur at the connections between various structures, and vibrations can occur due to inertial forces, leading to unstable equipment operation.

[0009] In summary, the limitations of the drive structure in existing disc-type precision metal processing machines prevent them from meeting the requirements for high-speed operation, necessitating improvements. Utility Model Content

[0077] Detailed implementation plan: See below Figures 1-28 This utility model is a hardware processing machine, comprising:

[0078] Rack 1;

[0079] The upper support frame 2 is installed above the frame 1 and is used to support the chassis 4. The chassis 4 is provided with a rotary support plate 5 and an upper plate 7 in sequence. The middle plate 6 is rotatably installed on the rotary support plate 5. Several chuck seats 9 are arranged around the middle plate 6, and several processing cutter heads 10 are arranged around the upper plate 7.

[0080] The rotary drive mechanism 3 includes a gear ring 61 mounted on the central plate 6, a first motor 31 fixed on the upper support frame 2, a shaft assembly linked to the first motor 31, and a gear 38 mounted on the shaft assembly. The gear 38 is meshed on the gear ring 61.

[0081] The main shaft drive mechanism 8 includes a second motor 81 fixed on the upper support frame 2, a lead screw assembly linked to the second motor 81, and a first nut seat 85 and a second nut seat 86 disposed on the lead screw assembly. A mounting seat 134 is mounted on the first nut seat 85, and an adapter seat 127 is mounted on the second nut seat 86.

[0082] The loading and unloading transmission assembly 12 is linked to the adapter 127 and is provided with at least one vertically arranged push rod 126, which is used to cooperate with the upper top chuck seat 9.

[0083] Several rocker arm assemblies 13 are arranged around the periphery of the mounting base 134, and each includes a second support 131 mounted above the upper plate 7, and a second rocker arm 132 rotatably mounted on the support. One end of the second rocker arm 132 is rotatably connected to the mounting base 134, and the other end is rotatably connected to the machining head 10.

[0084] The upper support frame 2 is also equipped with several third motors 11, which are used to drive the drive wheel 111 to rotate. A driven wheel 101 is provided above the machining head 10, and a synchronous belt is provided between the drive wheel 111 and the driven wheel 101.

[0085] Note that in this embodiment, the first motor 31, the second motor 81, and the third motor 11 are all servo motors.

[0086] As a preferred embodiment of this example, please refer to Figure 9 , Figure 10 , Figure 11 , Figure 24 and Figure 25 As can be seen, the lead screw assembly includes a first lead screw 82 linked to the second motor 81, and a second lead screw 84 disposed above the first lead screw 82 via a third coupling 83. A first nut seat 85 is mounted on the second lead screw 84, and a second nut seat 86 is mounted on the first lead screw 82.

[0087] Next, please refer to Figure 9 and Figure 10 As can be seen in this embodiment, the base 21 is provided with a first bearing seat 211, the second lead screw 84 is provided with a fourth bearing seat 41 and a fifth bearing seat 71, the first nut seat 85 is provided above the fifth bearing seat 71, the fourth bearing seat 41 is provided on the base plate 4, and the fifth bearing seat 71 is provided on the upper plate 7.

[0088] The working principle of the spindle drive mechanism 8 is as follows: When it is necessary to drive the mounting base 134 and the adapter 127 to rise and fall, the second motor 81 operates and drives the first lead screw 82 to rotate. Since a third coupling 83 is provided between the first lead screw 82 and the second lead screw 84, the second lead screw 84 can be driven to rotate. Since the second nut seat 86 is mounted on the first lead screw 82 and the adapter 127 is fixed on the second nut seat 86, the second nut seat 86 and the adapter 127 can be driven to rise and fall together along the first lead screw 82. Since the first nut seat 85 is mounted on the second lead screw 84 and the mounting base 134 is fixed on the first nut seat 85, the first nut seat 85 and the mounting base 134 can be driven to rise and fall together along the second lead screw 84.

[0089] Furthermore, in this embodiment, the arrangement of the first bearing housing 211, the fourth bearing housing 41, and the fifth bearing housing 71 makes the rotation of the lead screw assembly more stable and prevents wobbling during operation.

[0090] Then, please see Figure 1 , Figure 4 , Figure 16 , Figure 18 , Figure 19 and Figure 28 As can be seen, in this embodiment, the upper support frame 2 includes a base 21, which is fixed above the frame 1;

[0091] The glass cover 22 is positioned above the base 21;

[0092] Top cover 23 is located above glass cover 22;

[0093] The fixing plate 26 is set below the top cover 23 by several fixing rods 25, and the third motor 11 is installed on the fixing plate 26;

[0094] The support column 24 is fixed between the base 21 and the chassis 4.

[0095] In this embodiment, several support rods are provided between the upper plate 7 and the top cover 23. Therefore, even without the glass cover 22, the top cover 23 can be supported by the support rods. The glass cover 22 can rotate relative to the base 21 and the top cover 23. By rotating the glass cover 22, the glass cover 22 can be opened and closed.

[0096] Furthermore, in this embodiment, the support column 24 is a cast structure with high overall rigidity and excellent structural stability, which can firmly support the chassis 4, the slewing support plate 5, the middle plate 6, the upper plate 7, and the structures respectively set on it.

[0097] Then, please see Figures 16-20 As can be seen, in this embodiment, there is one driving wheel 111 connected to the same synchronous belt, and one, two or three driven wheels 101. The wheel width of both the driving wheel 111 and the driven wheel 101 is greater than the bandwidth of the synchronous belt.

[0098] In this embodiment, the timing belt, along with the driving pulley 111 and driven pulley 101 located on the timing belt, together form a timing belt pulley assembly. The fixed plate 26 has several clearance slots 261, which correspond in position to the driving pulley 111. The third motor 11 is fixed above the fixed plate 26 via a motor mounting plate 124, and the driving pulley 111 is located below the fixed plate 26.

[0099] Here, since the third motor 11 is relatively heavy, it is mounted on the fixed plate 26 to ensure stable installation of the third motor 11. In addition, by providing a clearance opening 261 on the fixed plate 26, it is convenient to install the drive pulley 111 on the motor shaft of the third motor 11, and to install a timing belt between the drive pulley 111 and the driven pulley 101.

[0100] As is well known, the driving pulley 111 and driven pulley 101 located on the same synchronous belt rotate at the same speed. Therefore, by adjusting the number of driven pulleys 101 located on the same synchronous belt, a single third motor 11 can control different numbers of driven pulleys 101 to maintain the same speed. In practical applications, machining heads 10 requiring the same speed can be rationally arranged on the same synchronous belt according to the required speed of the machining heads 10 at each workstation. This reduces the number of third motors 11, thereby reducing energy consumption and equipment costs.

[0101] During the operation of the metal processing machine, the processing head 10 needs to be driven to descend (how to drive the processing head 10 to rise and fall will be explained below) to process the metal parts fixed on the chuck 9. During the descent of the processing head 10, the driven wheel 101 also descends, while the driving wheel 111 remains in its original position. At this time, there is a height difference between the driving wheel 111 and the driven wheel 101. Since the width of both the driving wheel 111 and the driven wheel 101 is greater than the bandwidth of the synchronous belt, the normal operation of the synchronous belt will not be affected even though there is a height difference between the driven wheel 101 and the driving wheel 111.

[0102] As another preferred embodiment of this example, please refer to Figures 1-8 As can be seen, the shaft assembly includes:

[0103] The first shaft 34 is linked to the rotating shaft via the first coupling 33, and the rotating shaft is mounted on the motor shaft of the first motor 31;

[0104] The second shaft 36 is linked to the first shaft 34 via the second coupling 35, and the gear 38 is fixed to the upper end of the second shaft 36;

[0105] The motor shaft is provided with a second bearing seat 32, and the second shaft 36 is provided with a third bearing seat 37. The second bearing seat 32 is fixed on the base 21, and the third bearing seat 37 is fixed on the chassis 4.

[0106] Then, in this embodiment, the chassis 4 is provided with an opening 42 for the shaft assembly to pass through, the gear ring 61 is an internal gear ring 61, and the gear ring 61 is fixed below the middle plate 6. The outer periphery of the rotary support plate 5 is provided with a transition groove 51, and the upper part of the middle plate 6 is fixedly provided with a bearing outer ring 62. The bearing outer ring 62 is rotatably installed in the transition groove 51, and the bearing outer ring 62 is arranged inside the chuck seat 9. The upper end surface of the chassis 4 is provided with an annular groove 43 for the gear ring 61 to be placed.

[0107] Here, by fixing the outer ring 62 of the bearing above the middle plate 6 and setting the annular groove 43 on the upper surface of the chassis 4, the middle plate 6 can rotate more stably around the rotating support plate 5.

[0108] In this embodiment, the middle plate 6 is in a waiting state where it is stopped relative to the upper plate 7. In the waiting state, each chuck 9 is respectively positioned directly below each processing cutter head 10.

[0109] In addition, please see Figure 7 As can be seen, in this embodiment, a washer 74 and an oil pan 75 are fixed between the rotary support plate 5 and the upper plate 7, and the oil pan 75 is arranged around the washer 74.

[0110] Next, to ensure that the middle plate 6 does not wobble during rotation, please refer to... Figure 7As can be seen, in this embodiment, at least one stabilizing block 45 is provided on the periphery of the chassis 4, and a slot is provided on the edge of the middle plate 6 for one end of the stabilizing block 45 to extend into.

[0111] Working principle of rotary drive mechanism 3: The first motor 31 works and drives the first shaft 34 and the second shaft 36 to rotate. Since the gear 38 is fixed on the upper end of the second shaft 36, the gear 38 can be driven to rotate. Since the gear 38 meshes on the gear ring 61 and the gear ring 61 is fixed on the middle plate 6, the gear ring 61 and the middle plate 6 can be driven to rotate together.

[0112] Note that in this embodiment, the rotary drive mechanism 3 can drive the central plate 6 to rotate and stop intermittently to enter the processing state (equivalent to switching workstations, the same chuck 9 will stop sequentially under different processing cutters 10). In the processing state, the processing cutter 10 descends and processes the hardware located on the chuck 9.

[0113] In this embodiment, the structural design of the first motor 31 + gear 38 + gear ring 61 provides very stable driving and high driving precision. The first motor 31 can precisely control the stopping and starting of the middle plate 6, which can meet the high-speed operation of the equipment.

[0114] Please see Figures 13-15 As can be seen, a swing arm plate is fixedly installed above the upper plate 7, and several second supports 131 are fixedly installed above the swing arm plate. The outer wall of the mounting base 134 is surrounded by a groove 1341. One end of the second swing arm 132 is provided with a roller, which extends into the groove 1341.

[0115] Then, in this embodiment, the processing head 10 is provided with a connecting plate 103, and a guide rod 102 arranged vertically is fixed on the connecting plate 103. The edge of the upper plate 7 is surrounded by a plurality of guide holes 73, and the guide rod 102 is inserted into the guide holes 73. The upper end of the guide rod 102 extends above the connecting plate 103 and forms an upper section. Two transition blocks 104 arranged vertically are fixed on the upper section. The ends of the two transition blocks 104 that are close to each other are arc-shaped. The end of the second swing rod 132 is fixed with a connecting block 133, and the connecting block 133 extends into the space between the two transition blocks 104.

[0116] Furthermore, in this embodiment, the edge of the upper plate 7 is provided with a plurality of openings 72 for the lower end of the machining head 10 to pass through.

[0117] In this embodiment, the guide rod 102 and the guide hole 73 can guide the lifting direction of the machining head 10, thereby making the machining head 10 lift more smoothly along the extension direction of the opening 72.

[0118] The working principle of the rocker arm assembly 13 is as follows: One end of the second rocker arm 132 is rotatably connected to the slot 1341 of the mounting base 134 via a roller, while the other end is placed between two adapter blocks 104. When the mounting base 134 rises, it will cause one end of the second rocker arm 132 to rise along with it. According to the lever principle, the second rocker arm 132 rotates around the second support 131 at this time, driving the other end of the second rocker arm 132 to descend, thereby driving the machining head 10 to descend.

[0119] Here, the arrangement of the rocker arm assembly 13 results in a smaller force acting on the mounting base 134 when driving the machining head 10 to rise and fall, thus saving more effort and making the equipment run more stably.

[0120] For more details, please see Figures 21-27 As can be seen, the loading and unloading transmission assembly 12 includes:

[0121] Mounting plate 124 is fixed below chassis 4;

[0122] The fixing block 125 is slidably mounted on the mounting plate 124 in a vertical direction, and the top rod 126 is fixed on the fixing block 125;

[0123] The first support 121 is fixed above the base 21;

[0124] The first swing arm 122 is rotatably mounted on the first support 121. One end of the first swing arm 122 is rotatably connected to the adapter 127, and the other end abuts against the bottom of the fixing block 125.

[0125] In this embodiment, the chassis 4 is provided with a plurality of mutually spaced first through holes 44, and the middle plate 6 is provided with a plurality of mutually spaced second through holes 63, the first through holes 44 and the second through holes 63 being vertically aligned.

[0126] In addition, in this embodiment, a vertically extending slide bar 1241 is provided on one side of the mounting plate 12474, and a slider 1251 for sliding on the slide bar 1241 is provided on the fixing block 125.

[0127] Here, by setting a slide bar 1241 on the mounting plate 124 and a slider 1251 on the fixing block 125, the fixing block 125 can be raised and lowered more stably along the mounting plate 124.

[0128] Next, please refer to Figure 24 and Figure 27 As can be seen, in order to make the end of the first swing arm 122 away from the adapter seat 127 better abut against the bottom of the fixed block 125, in this embodiment, the end of the first swing arm 122 is provided with a rotating rod 123, and a bearing 1231 is installed on the rotating rod 123, and the bearing 1231 abuts against the bottom of the fixed block 125.

[0129] The working principle of the loading / unloading transmission assembly 12 is as follows: Since the first swing rod 122 rotates around the first support 121, and one end of the first swing rod 122 is rotatably connected to the adapter 127, when the adapter 127 descends, based on the lever principle, the end of the first swing rod 122 away from the adapter 127 will rise, thereby pushing the fixed block 125 upward. At this time, the push rod 126 fixed on the fixed block 125 will sequentially enter the first through hole 44 and the second through hole 63, and push the chuck seat 9 upward, causing the chuck seat 9 to loosen. After the chuck seat 9 is loosened, hardware parts can be loaded and unloaded on the chuck seat 9.

[0130] After the hardware parts are unloaded and loaded, the adapter 127 rises. Similarly, this causes the end of the first swing rod 122 away from the adapter 127 to descend. At this time, the fixed block 125 and the push rod 126 will descend together with the end of the first swing rod 122 under the action of gravity. Note that during this process, the fixed block 125 and the bearing 1231 located at the end of the first swing rod 122 remain in contact. After the push rod 126 descends, the chuck 9 will clamp the hardware parts located on it.

[0131] Then, please see Figure 21 , Figure 22 and Figure 27 As can be seen, in this embodiment, two spaced-apart top rods 12676 are fixedly provided on the fixing block 125.

[0132] In addition, please see Figure 21 and Figure 23 As can be seen, in this embodiment, there are two loading and unloading transmission components 12, which are respectively arranged on opposite sides of the adapter 127.

[0133] Here, by setting transmission components on both sides of the adapter 127, and setting two push rods 126 in each transmission component 7, a two-in-two-out loading and unloading method can be realized.

[0134] To make it easier to understand, the following example illustrates the machining process of one of the chuck holders 9: Please refer to... Figure 21 and Figure 22A rotary drive mechanism 3 is installed on the base 21. The rotary drive mechanism 3 drives the middle plate 6 to rotate, causing the chuck 9 located on the middle plate 6 to pass through multiple different processing stations in sequence. When the chuck 9 passes through one of the transmission components, one of the push rods 126 pushes up, causing the chuck 9 to loosen. At this time, the hardware part can be loaded onto the chuck 9. Then, as the push rod 126 descends, the hardware part is clamped by the chuck 9. After the chuck 9 rotates half a turn, the hardware part on it has been processed. When it passes through another transmission component, one of the push rods 126 pushes up, and similarly, the processed hardware part can be removed from the chuck 9. Therefore, it is equivalent to the chuck 9 completing one loading and unloading cycle after rotating half a turn with the middle plate 6, greatly improving processing efficiency.

[0135] In this embodiment, the operation of the first motor 31, the second motor 81 and the third motor 11 can all be controlled by a PLC, and the hardware processing machine is equipped with a touch screen for adjusting PLC parameters.

[0136] The hardware processing machine of this utility model described above is only a preferred embodiment of this utility model and does not limit the patent scope of this utility model. All equivalent structural transformations made under the inventive concept of this utility model using the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
