Description

Technical Field

[0002] To meet the diverse processing needs of users, modern mechanical parts processing equipment is usually designed to have multiple working modes.

[0003] A mainstream technological approach to achieving functional versatility is to adopt a replaceable structure, which changes the way parts are processed by replacing machining heads or accessories with different functions and shapes. This design allows users to flexibly select and install the most suitable machining molds according to different part processing requirements, thereby greatly expanding the applicability and practical value of a single device.

[0004] However, existing connection and locking structures for replacing processing heads or functional accessories still fall short in terms of ease of operation. The replacement process for many products is cumbersome, requiring users to use both hands to painstakingly align the clips or threads and perform locking or unlocking operations one by one. This is especially true for structures requiring simultaneous locking from both sides, where the process is even more complex. This not only reduces replacement efficiency but also inconveniences users, impacting the user experience and discouraging frequent replacements of functional accessories. Consequently, the multi-functional advantages of the equipment are not fully realized.

[0005] Therefore, this utility model proposes a flipping clamping device for manufacturing mechanical parts to overcome the shortcomings of the prior art. Utility Model Content

[0022] Example

[0023] Please refer to Figures 1 to 4This utility model provides a flipping clamping device for manufacturing mechanical parts, which aims to solve the problems in the prior art where the process of changing the processing head or functional plate is complicated and time-consuming, and the clamping mechanism is difficult to quickly and stably fix objects of different sizes.

[0024] like Figure 1 and Figure 2 As shown, this flipping and clamping device for manufacturing mechanical parts includes multiple support columns 1 for support, a support platform 2 fixed to the top of the support columns 1, a support frame 6 disposed above the support platform 2, a flipping plate 4 rotatably connected to the support platform 2, a flipping mechanism 3 for driving the flipping plate 4 to flip, a positioning mechanism 5 disposed on the flipping plate 4 for clamping and positioning, and a processing plate 77 replaceably mounted on the support frame 6. The support columns 1 are in contact with the ground to distribute the pressure generated during equipment operation, and the support platform 2 provides working space for the workpiece after it enters. The core of the clamping device is a replacement mechanism 7 for quickly installing and removing the processing plate 77 from the support frame 6. The replacement mechanism 7 includes a fixing block 72 fixedly connected to the support frame 6 and a rotating part connected to the fixing block. The replacement mechanism 7 includes a rotating gear 74 and two sliding racks 75 that are slidably mounted on the processing plate 77 and simultaneously mesh with the rotating gear 74. The replacement mechanism 7 also includes a locking assembly for locking the two sliding racks 75. The locking assembly includes a limiting shaft 78 that can be plugged into the sliding racks 75 and a spring 79 for driving the limiting shaft 78 to reset. By manually pulling the limiting shaft 78, the sliding block 710 is driven to compress the spring 79 and deform it, which in turn pushes one of the sliding racks 75. Then, through meshing with the rotating gear 74, the rotating gear 74 is rotated. The rotation of the rotating gear 74 drives the other sliding rack 75 to slide, thereby completing the disassembly of the processing plate 77 and the fixing block 72, realizing the quick and tool-free disassembly and assembly of the functional plate.

[0025] Please refer to the following carefully. Figure 2 , Figure 3 and Figure 4 The clamping device includes a flipping mechanism 3 for driving the flipping plate 4 to flip. The flipping mechanism 3 includes a support plate 31 fixed to the support platform 2, a motor 32 mounted on the support plate 31, and a drive shaft 33 with one end connected to the output end of the motor 32 and the other end fixedly connected to the flipping plate 4. The support plate 31 provides a mounting base for the stable operation of the motor 32. The motor 32 outputs power and drives the entire flipping plate 4 to rotate around the axis of the drive shaft 33 through the drive shaft 33, thereby realizing multi-angle operation of the clamped workpiece. Meanwhile, a positioning mechanism 5 is provided on the flip plate 4. The positioning mechanism 5 includes a drive assembly 51, two rotating plates 52 that are linked to the output end of the drive assembly 51, two sliding shafts 53 that are driven by the rotating plates 52 respectively, and positioning rods 54 that are fixedly connected to the two sliding shafts 53 respectively. Specifically, the drive assembly 51 includes a cylinder 511 fixed inside the flip plate 4 and a sliding plate 512 connected to the piston rod of the cylinder 511 and used to drive the two rotating plates 52. During operation, the cylinder 511 drives the sliding plate 512 to move linearly. The sliding plate 512 drives the two rotating plates 52 to rotate around their respective fulcrums. The rotation of the rotating plates 52 is then converted into linear motion of the two sliding shafts 53 in opposite directions or away from each other, thereby driving the two positioning rods 54 to achieve synchronous clamping or loosening of the workpiece. To improve the clamping effect, a rubber block 56 is fixedly connected to the side of the positioning rod 54 facing the clamping center. The elastic properties of the rubber block 56 are used to prevent the workpiece surface from being crushed, and at the same time to accommodate small deviations in the workpiece size to achieve tight positioning. In addition, the positioning mechanism 5 also includes a support shaft 55 with its two ends connected to the two positioning rods 54 respectively. The support shaft 55 is used to provide stable support during the sliding process of the positioning rods 54 to prevent them from shifting and to ensure the stability and accuracy of clamping.

[0026] To achieve stable sliding and precise positioning of the replacement mechanism 7, two limiting blocks 76 are fixedly connected to the fixed block 72. The free ends of the two sliding racks 75 are slidably inserted into the corresponding limiting blocks 76. This structure provides guidance for the linear movement of the sliding racks 75. At the same time, the rotating gear 74 is rotatably connected to the fixed block 72 through the fixed shaft 73. The fixed shaft 73 provides a stable rotation center for the rotating gear 74, ensuring the reliability of its meshing transmission.

[0027] Furthermore, in order to reliably lock the sliding rack 75, the locking assembly also includes a sliding block 710 fixedly connected to one end of the limiting shaft 78, and a spring 79 sleeved on the limiting shaft 78, with its two ends elastically abutting against the sliding block 710 and the processing plate 77 respectively. In the locked state, the spring 79 pushes the sliding block 710 and the limiting shaft 78 into the corresponding slot of the sliding rack 75 to achieve a stable lock. When unlocking is required, external force can overcome the elastic force of the spring 79 to achieve separation.

[0028] As a specific driving method, the replacement mechanism 7 also includes a second cylinder 71. The cylinder body of the second cylinder 71 is fixedly connected to the fixed block 72, and its piston rod is used to drive the processing plate 77 to perform processing actions. Through the reciprocating motion of the second cylinder 71, the entire processing plate 77 is driven to execute the preset processing program.

[0029] To ensure the stability of the entire device, the clamping device also includes multiple support columns 1 fixed to the ground and used to support the support platform 2. The load and vibration of the device during operation are effectively transmitted to the ground through the multiple support columns 1, ensuring the overall stability of the device during operation.

[0030] The working principle is as follows: First, when the workpiece needs to be clamped and positioned, the cylinder 511 in the positioning mechanism 5 is activated. The cylinder 511 drives the sliding plate 512 to slide inside the flipping plate 4, and drives the two rotating plates 52 to rotate through the shaft. The rotation of the rotating plates 52 further drives the two sliding shafts 53 to slide stably relative to each other inside the flipping plate 4, thereby driving the two positioning rods 54 fixed on the sliding shafts 53 to perform synchronous clamping or loosening actions to adaptively fix workpieces of different sizes. During this process, the rubber block 56 is in contact with the outer wall of the workpiece, which plays a role in protection and tight fit. The support shaft 55 provides stable support for the sliding of the positioning rods 54 to prevent them from shifting. When the workpiece posture needs to be adjusted, the motor 32 in the flipping mechanism 3 is activated. The motor 32 drives the entire flipping plate 4 together with the clamped workpiece to flip to a predetermined angle through the drive shaft 33.

[0031] When the workpiece needs to be processed, the piston rod of cylinder 71 in the changing mechanism 7 drives the entire processing plate 77 to perform a preset reciprocating motion to achieve the processing function. The entire changing mechanism 7 is stably supported by the support frame 6 to prevent it from shaking during operation. When it is necessary to change the processing plate 77 with different functions, the two limiting shafts 78 are manually pulled outward. The limiting shafts 78 drive the sliding block 710 to compress the spring 79 and deform it, so that the limiting shafts 78 are disengaged from the locking with the sliding rack 75. At this time, one of the sliding racks 75 is pushed to slide away from the inside of the limiting block 76. The sliding rack 75 drives the rotating gear 74 to rotate through meshing with the rotating gear 74. The rotating gear 74 then drives the other sliding rack 75 to slide away from the corresponding limiting block 76 in the opposite direction, thereby completing the quick disassembly of the processing plate 77 and the fixing block 72.

[0032] When installing a new processing plate 77, it is placed at the bottom of the fixing block 72. Pulling one of the sliding racks 75 drives the rotating gear 74 to rotate, which in turn drives the other sliding rack 75 to slide. When the two sliding racks 75 slide into the interior of the two limiting blocks 76 and reach the predetermined position, the spring 79 releases its elastic force, and the limiting shaft 78 is pushed by the sliding block 710 to automatically embed into the interior of the sliding rack 75, thereby completing the quick installation and locking of the new processing plate 77. Through this synergistic effect of the rotating gear 74 and the sliding rack 75 in the replacement mechanism 7, this utility model solves the problem of complex and time-consuming functional head replacement process in the prior art, and significantly improves the ease of use of the equipment.
