Description

Technical Field

[0001] This utility model relates to the field of hardware processing equipment, and in particular to a loading and unloading drive mechanism for 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. In this design, the opening and closing of the chucks are controlled by a push rod. When the push rod is pushed upward, the chuck is released, allowing the loading and unloading of hardware parts to be completed on that chuck. The other chucks not pushed upward remain clamped to the hardware 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 set 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. The up and down movement of the lifting rod drives the drive rod and connecting rod to rise and fall, thereby driving 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 of various structures. Even a small error can lead to a decrease in motion accuracy. In addition, once the equipment is running at high speed, fatigue wear is likely to occur at the joints of various structures, and vibration will be generated due to the influence of inertial forces, which will lead to unstable operation of the equipment and reduced service life, requiring improvement.

[0005] Furthermore, in the above scheme, the push rod is only set on one side below the chassis. That is to say, the push rod will only pass through once after the chuck has rotated a full circle, and only then can a loading and unloading action be completed. If the processing procedure of the hardware is not complicated, there is no need to process it through multiple processing stations. This structure will result in low processing efficiency of the hardware. Utility Model Content

[0006] To solve the above problems, this utility model proposes a loading and unloading drive mechanism for a hardware processing machine.

[0007] The technical solution adopted by this utility model is: a loading and unloading drive mechanism for a hardware processing machine. The hardware processing machine includes a frame and an upper support frame installed above the frame. The upper support frame is used to support a chassis. A rotary support plate and an upper plate are sequentially arranged above the chassis. A middle plate is rotatably mounted on the rotary support plate. A plurality of mutually spaced first through holes are arranged around the chassis. A plurality of mutually spaced second through holes are arranged around the middle plate. The first through holes and the second through holes are vertically corresponding, and a chuck seat is installed on the second through hole. The loading and unloading drive mechanism includes:

[0008] The drive device includes a servo motor mounted on the upper support frame, a lead screw linked to the servo motor, a nut seat mounted on the lead screw, and an adapter seat fixed on the nut seat;

[0009] The transmission assembly is linked to the adapter seat and has at least one vertically arranged push rod, the push rod and the first through hole being vertically aligned.

[0010] Several alternative methods are provided below, but they are not intended as additional limitations on the overall solution above. They are merely further additions or optimizations. Provided there are no technical or logical contradictions, each alternative method can be combined individually with respect to the overall solution above, or multiple alternative methods can be combined with each other.

[0011] Preferably, the upper support frame includes a base fixed above the frame and a support column fixed above the base, the chassis is mounted above the support column, and the servo motor is fixedly mounted on the base.

[0012] Preferably, the transmission assembly includes:

[0013] Mounting plate, fixed under the chassis;

[0014] A fixing block is slidably mounted vertically on the mounting plate, and the top rod is fixed on the fixing block;

[0015] Support, fixed above the base;

[0016] A swing arm is rotatably mounted on the support, with one end of the swing arm rotatably connected to the adapter and the other end abutting against the bottom of the fixed block.

[0017] Preferably, one side of the mounting plate is provided with a vertically extending slide bar, and the fixing block is provided with a slider for slidingly mounting on the slide bar.

[0018] Preferably, the end of the swing arm is provided with a shaft, and a bearing is installed on the shaft, with the bearing abutting against the bottom of the fixed block.

[0019] Preferably, the fixing block is fixed with two spaced-apart top rods.

[0020] Preferably, there are two transmission components, which are respectively disposed on opposite sides of the adapter.

[0021] More preferably, the lower end of the push rod is threaded onto the fixing block, and the push rod passes through the fixing block.

[0022] Compared with the prior art, this utility model has the following beneficial effects:

[0023] 1. The adapter seat is driven to rise and fall along the screw using a servo motor and ball screw. Since the swing arm is rotatably mounted on the support, one end of the swing arm is rotatably connected to the adapter seat, and the other end abuts against the bottom of the fixed block. According to the lever principle, when the adapter seat falls, the other end of the swing arm falls and rises, thereby driving the fixed block and the top rod to rise. When the adapter seat rises, the other end of the swing arm falls. At this time, the fixed block and the top rod automatically fall under the action of gravity. The servo motor drive method allows for convenient parameter adjustment. The lifting speed and lifting distance of the top rod can be adjusted according to the requirements. The drive is precise and can meet the high-speed operation of the equipment. The structure is stable and the equipment has a long service life.

[0024] 2. By setting transmission components on opposite sides of the adapter, a two-in, two-out structure design is provided. After the hardware is loaded onto the chuck and rotates half a turn, it can be unloaded without waiting for a full rotation. This is suitable for hardware processing with simple processing procedures and results in higher processing efficiency. Attached Figure Description

[0039] Detailed implementation plan: See below Figures 1-8 This utility model relates to a loading and unloading drive mechanism for a hardware processing machine. The hardware processing machine includes a frame 1 and an upper support frame 2 mounted above the frame 1. The upper support frame 2 is used to support a chassis 8. A rotary support plate and an upper plate are sequentially arranged above the chassis 8. A middle plate 9 is rotatably mounted on the rotary support plate. The chassis 8 has a plurality of mutually spaced first through holes 81, and the middle plate 9 has a plurality of mutually spaced second through holes 91. The first through holes 81 and the second through holes 91 are vertically aligned, and a chuck seat 10 is mounted on the second through hole 91. The loading and unloading drive mechanism includes:

[0040] The drive unit includes a servo motor 3 mounted on the upper support frame 2, a lead screw 4 linked to the servo motor 3, a nut seat 5 mounted on the lead screw 4, and an adapter seat 6 fixed on the nut seat 5.

[0041] The transmission assembly 7 is linked to the adapter 6 and has at least one vertically arranged push rod 76, with the push rod 76 corresponding to the upper and lower positions of the first through hole 81.

[0042] Working principle of the drive device: The servo motor 3 works and drives the lead screw 4 to rotate. Since the nut seat 5 is installed on the lead screw 4 and the adapter seat 6 is fixed on the nut seat 5, the nut seat 5 and the adapter seat 6 can be driven to move up and down together along the lead screw 4.

[0043] Please see Figure 2 As can be seen, in this embodiment, the upper support frame 2 includes a base 21 fixed above the frame 1 and a support column 22 fixed above the base 21. The chassis 8 is installed above the support column 22, and the servo motor 3 is fixedly installed on the base 21.

[0044] As a preferred embodiment of this example, please refer to Figure 1 , Figures 4-6 As can be seen, the transmission assembly 7 includes:

[0045] Mounting plate 74 is fixed below chassis 8;

[0046] The fixing block 75 is slidably mounted on the mounting plate 74 in a vertical direction, and the top rod 76 is fixed on the fixing block 75;

[0047] Support 71 is fixed above base 21;

[0048] The rocker arm 72 is rotatably mounted on the support 71. One end of the rocker arm 72 is rotatably connected to the adapter 6, and the other end abuts against the bottom of the fixing block 75.

[0049] In addition, in this embodiment, a vertically extending slide bar 741 is provided on one side of the mounting plate 74, and a slider 751 for sliding on the slide bar 741 is provided on the fixing block 75.

[0050] Here, by setting a slide bar 741 on the mounting plate 74 and a slider 751 on the fixing block 75, the fixing block 75 can be raised and lowered more stably along the mounting plate 74.

[0051] Next, please refer to Figure 6 As can be seen, in order to make the end of the swing arm 72 away from the adapter seat 6 better abut against the bottom of the fixing block 75, in this embodiment, the end of the swing arm 72 is provided with a shaft 73, and a bearing 731 is installed on the shaft 73, and the bearing 731 abuts against the bottom of the fixing block 75.

[0052] The working principle of the transmission component 7: Since the rocker arm 72 rotates around the support 71, and one end of the rocker arm 72 is rotatably connected to the adapter 6, when the adapter 6 descends, based on the lever principle, it will drive the end of the rocker arm 72 away from the adapter 6 to rise, which in turn will push the fixed block 75 to rise. At this time, the push rod 76 fixed on the fixed block 75 will sequentially enter the first through hole 81 and the second through hole 91, and push the chuck seat 10 upward, causing the chuck seat 10 to be released. After the chuck seat 10 is released, hardware parts can be loaded and unloaded on the chuck seat 10.

[0053] After the hardware parts are unloaded and loaded, the adapter 6 rises. Similarly, this causes the end of the swing rod 72 away from the adapter 6 to descend. At this time, the fixed block 75 and the push rod 76 will descend together with the end of the swing rod 72 under the action of gravity. Note that during this process, the fixed block 75 and the bearing 731 located at the end of the swing rod 72 remain in contact. After the push rod 76 descends, the chuck 10 will clamp the hardware parts located on it.

[0054] Then, please see Figure 2 , Figure 3 and Figure 6 As can be seen, in this embodiment, two spaced-apart top rods 76 are fixedly provided on the fixing block 75.

[0055] In addition, please see Figure 1 and Figure 4As can be seen, in this embodiment, there are two transmission components 7, which are respectively arranged on opposite sides of the adapter 6.

[0056] Here, by setting transmission components 7 on both opposite sides of the adapter 6, and setting two push rods 76 in each transmission component 7, a two-in-two-out loading and unloading method can be realized.

[0057] To make it easier to understand, the machining process of one of the chuck seats 10 is shown below as an example: Please refer to... Figure 1 and Figure 2 A rotary drive mechanism 11 is installed on the base 21. The rotary drive mechanism 11 drives the middle plate 9 to rotate, causing the chuck 10 located on the middle plate 9 to pass through multiple different processing stations in sequence. When the chuck 10 passes through one of the transmission components 7, one of the push rods 76 pushes up, causing the chuck 10 to loosen. At this time, the hardware part can be loaded onto the chuck 10. Then, as the push rod 76 descends, the hardware part is clamped by the chuck 10. After the chuck 10 rotates half a turn, the hardware part on it has been processed. When it passes through another transmission component 7, one of the push rods 76 pushes up, and similarly, the processed hardware part can be removed from the chuck 10. Therefore, it is equivalent to the chuck 10 completing one loading and unloading cycle after rotating half a turn with the middle plate 9, greatly improving processing efficiency.

[0058] For more details, please see Figure 6 To facilitate adjustment of the vertical position of the push rod 76, in this embodiment, the lower end of the push rod 76 is threaded onto the fixing block 75, and the push rod 76 passes through the fixing block 75.

[0059] The above description of the loading and unloading drive mechanism of the hardware processing machine of this utility model 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 in the patent protection scope of this utility model.
