Description

Technical Field

[0001] This invention belongs to the technical field of hardware tool processing equipment, specifically referring to a tool pliers cutting edge processing equipment. Background Technology

[0002] Pliers are a widely used manual tool primarily used for clamping and securing various workpieces. They can also perform tasks such as twisting metal parts, bending metal materials, and cutting metal wires. These tools have extremely wide applications in both industrial manufacturing and everyday household life.

[0003] The performance of a pair of pliers largely depends on the quality of its cutting edge machining. A high-quality cutting edge not only significantly improves tool efficiency but also extends its lifespan. Therefore, cutting edge machining is a crucial process in pliers manufacturing.

[0004] Existing technologies for machining the cutting edges of pliers have several limitations: In terms of machining accuracy, the repeatability of workpiece positioning is insufficient. Most existing fixtures use planar clamping structures, which cannot be adapted to the beveled features of the plier cutting edges, leading to uneven force on the cutting edges during grinding, causing chatter and directly affecting surface roughness. In the unloading stage, most equipment still uses manual unloading, which not only increases labor intensity but also easily leads to scratches on the finished product due to operational errors. Regarding machining efficiency, single-station sequential machining requires multiple manual clamping and handling, resulting in low production efficiency. Summary of the Invention In view of the above situation and to overcome the defects of the prior art, the purpose of the present invention is to provide a tool and pliers cutting edge processing device to at least partially solve the problems mentioned in the background art.

[0005] The technical solution adopted by this invention is as follows: A tool and pliers cutting edge processing device is proposed, comprising: A rotating support frame is connected to a rotary motor via a connecting shaft and is configured to rotate under drive. The rotating support frame has three circumferentially distributed workstations: an installation workstation, a grinding workstation, and an unloading workstation. The rotating support frame includes multiple support modules, and the rotary motor drives the support modules to pass through each workstation in sequence. A clamping mechanism is provided on the bearing module. The clamping mechanism includes a clamping plate. The surface of the clamping plate is provided with a fixing groove. The bottom surface of the fixing groove is provided with an inclined plane to adapt to the installation posture of the tool pliers cutting edge. After the tool pliers are installed, the cutting edge of the tool pliers is flush with the upper surface of the clamping plate. The unloading mechanism, located at the unloading station, includes a top rod on the support frame and an unloading spring in the bearing module. The unloading spring cooperates with the top rod to push the polished tool pliers out of the clamping mechanism.

[0006] Furthermore, it also includes a grinding mechanism, a discharge plate, and a collection mechanism. The collection mechanism is disposed between the grinding mechanism and the support frame, and the discharge plate is disposed below the discharge station. The discharge plate is connected to the collection mechanism.

[0007] Furthermore, the load-bearing modules are provided with connecting rods and fixing blocks, the rear side of the fixing block is connected to the connecting shaft, and the load-bearing modules are disposed on the side of the fixing block.

[0008] Furthermore, the bearing module also includes a bearing frame and a telescopic rod. The bottom of the bearing frame is provided with a slide rail, which is slidably connected to the clamping mechanism. The bearing frame and the telescopic rod are respectively connected to the side of the fixed block. The telescopic rod is fixedly connected to the clamping plate, and the telescopic rod drives the clamping plate to move. The unloading spring is connected to the carrier frame via a connecting block.

[0009] Furthermore, the clamping mechanism also includes a slider, a limiting post, and a connecting sleeve. The slider is disposed at the bottom of the clamping plate and is slidably connected to the slide rail. The limiting post is disposed in the fixing groove and is connected to the connecting hole on the tool pliers. The height of the limiting post is lower than the surface of the clamping plate. The connecting sleeve is disposed on the side of the clamping plate, and the connecting sleeve is fixedly connected to the telescopic rod.

[0010] Furthermore, the support frame also includes a crossbar, a fixed bushing, and a support rod. The crossbar is located at the grinding station, the support rod is located at the rear side of the support frame, the connecting shaft passes through the fixed bushing and is connected to the rotary motor, and the bottom of the support frame is connected to the collecting mechanism.

[0011] Furthermore, the grinding mechanism includes a control cabinet, a grinding wheel, and a baffle. The baffle is arranged around the grinding wheel, and the bottom of the baffle is connected to the collecting mechanism. The control cabinet is electrically connected to the grinding wheel and the rotating support frame.

[0012] The beneficial effects of this invention are: This tool pliers cutting edge machining equipment achieves significant technological advancements through its rotary multi-station design and specialized clamping mechanism: Firstly, by integrating the installation, grinding, and unloading processes into a continuous flow, the waiting time for individual parts processing is eliminated, thereby improving production efficiency.

[0013] Secondly, the design of the fixed groove eliminates the need for frequent adjustments of traditional clamps; the inclined plane of the bottom of the fixed groove matches the cutting edge angle of the tool pliers, so that the cutting edge is subjected to uniform force and there is no chatter during the grinding process, which effectively improves the quality of the cutting edge grinding.

[0014] Third, the mechanical linkage between the push rod and the unloading spring achieves non-destructive material feeding, which, together with the unloading plate, reduces the risk of finished product damage and improves the quality of blade grinding. Attached Figure Description

[0018] The technical solutions in 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, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.

[0019] In the description of the embodiments, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments.

[0020] This invention provides a tool cutting edge machining device, such as... Figures 1-8 As shown, in some embodiments, it includes: A rotating support frame 2 is reliably connected to a rotary motor via a connecting shaft 21, and the rotary motor drives the rotating support frame 2 to rotate. Specifically, at least three workstations are distributed circumferentially on the rotating support frame 2, including an installation workstation for fixing the tool pliers 4 to be processed, a grinding workstation equipped with a grinding wheel 12, and an unloading workstation for automatic unloading. Integrating the installation, grinding, and unloading processes into a continuous process eliminates the waiting time for single-piece processing and improves production efficiency.

[0021] The rotating support frame 2 includes multiple support modules 22, which, driven by a rotary motor, can be positioned at various processing stations according to a preset processing route. This multi-station design enables continuous assembly line operation, eliminating waiting time between processes.

[0022] Multiple clamping mechanisms 3 are mounted on the carrier module 22 to clamp the tool pliers 4 to be processed, and to carry the tool pliers 4 to different workstations via the carrier module 22. Specifically, the clamping mechanism 3 includes a clamping plate 31 and a fixing groove 33 on the surface of the clamping plate 31. In particular, the bottom surface of the fixing groove 33 is provided with an inclined plane, the inclination angle of which is the same as the inclination angle of the cutting edge of the tool pliers 4, ensuring that after the tool pliers 4 is installed in place, its cutting edge processing plane can maintain a strict parallel relationship with the upper reference surface of the clamping plate 31, thereby achieving precise processing positioning accuracy.

[0023] It should be noted that the design of the fixing groove 33 eliminates the need for frequent adjustments of traditional clamps; the inclined plane of the bottom surface of the fixing groove 33 matches the cutting edge angle of the tool pliers 4, which makes the cutting edge evenly stressed and eliminates chatter during the grinding process, effectively improving the quality of the cutting edge grinding.

[0024] In addition, this embodiment also includes an unloading mechanism, which is set at the unloading station to improve processing efficiency. The unloading mechanism includes a push rod 53 on the support frame 5 and an unloading spring 223 in the bearing module 22. When the finished tool pliers 4 rotates with the bearing module 22 to the unloading station, the push rod 53 moves upward and contacts the bottom surface of the unloading spring 223, causing the unloading spring 223 to be pushed upward. The top surface of the unloading spring 223 contacts the finished tool pliers 4, smoothly pushing it out of the clamping mechanism 3. The whole process realizes automated unloading and ensures the stability of product processing quality.

[0025] The mechanical linkage between the push rod 53 and the unloading spring 223 enables non-destructive unloading, which, in conjunction with the unloading plate 6, reduces the risk of damage to the finished product and improves the quality of the cutting edge grinding.

[0026] The specific operation process of this embodiment is as follows: Material loading stage: The operator places the tool pliers 4 to be processed into the fixing slot 33 of the installation station, and the tool pliers 4 is fixed by the side wall of the fixing slot 33.

[0027] Rotation phase: After clamping is completed, the rotary motor starts, driving the rotary support frame 2 to rotate, rotating the support module 22 holding the tool clamp 4 to the grinding station. At the same time, the ground tool clamp 4 rotates to the unloading station, and the empty support module 22 rotates to the installation station.

[0028] Grinding stage: At the grinding station, the cutting edge of tool pliers 4 is ground.

[0029] Unloading stage: At the unloading station, the push rod 53 on the support frame 5 contacts the unloading spring 223 and compresses it to deform. As the push rod 53 continues to move upward, it lifts the unloading spring 223 upward and pushes it against the handle of the tool pliers 4, thereby pushing the entire tool pliers 4 out of the fixing groove 33.

[0030] Cyclic phase: The rotating support frame 2 continues to rotate, repeating the above process to achieve continuous automated processing.

[0031] like Figures 1-3 As shown, in some embodiments, the device further includes a grinding mechanism 1, a discharge plate 6, and a collection mechanism 7. The grinding mechanism 1, as a finishing unit, is used to finely grind the pre-processed cutting edge to ensure that the surface finish and dimensional accuracy of the cutting edge meet the process requirements. The collection mechanism 7 is optimally positioned between the grinding mechanism 1 and the support frame 5. This arrangement facilitates the collection of debris and lubricant generated during the grinding process, ensuring a clean operating space and facilitating the recycling of lubricant.

[0032] The unloading plate 6 is installed directly below the unloading station and has an inclined angle to ensure that the processed workpiece slides down smoothly and stably under the action of gravity. To ensure the stability of the unloading plate 6, its bottom is connected to the collection mechanism 7, thus forming a complete workpiece collection system. This improves the automation level and production efficiency of the entire processing process, while also reducing the frequency and intensity of manual intervention.

[0033] like Figures 3-4 As shown, in some embodiments, adjacent support modules 22 are effectively connected by a connecting rod 23 to ensure the stability of the support module 22. Simultaneously, the support module 22 is connected to the connecting shaft 21 via a fixing block 24 to ensure the stability of the overall structure. Specifically, the fixing block 24 has five sides, each connected to a support module 22. The connecting shaft 21 drives the fixing block 24 to rotate, simultaneously driving the support module 22 to switch between three workstations.

[0034] Furthermore, in some embodiments, the specific structural composition of the bearing module 22 also includes two main components: a bearing frame 221 and a telescopic rod 225. The bearing frame 221 is made of alloy material, and its bottom is machined to form a linear slide rail 222 structure. The surface of the slide rail 222 needs to have wear-resistant properties. The slide rail 222 is connected to the clamping mechanism 3 by a sliding fit, enabling the clamping mechanism 3 to move smoothly and without gaps along the slide rail 222. Each side of the fixing block 24 is respectively provided with connections to the bearing frame 221 and the telescopic rod 225.

[0035] Specifically, the telescopic rod 225 adopts a hydraulic cylinder structure, and its output end is rigidly connected to the clamping plate 31, with the connection part designed to prevent loosening. When the telescopic rod 225 receives a drive signal from the control system, its piston rod, under the precise guidance of the guide sleeve, drives the clamping plate 31 to perform linear reciprocating motion, thereby realizing the grinding process of the tool pliers 4.

[0036] The unloading spring 223 is connected to the support frame 221 by a connecting block 224, which enables the unloading spring 223 to effectively lift the handle of the tool pliers 4. This causes the tool pliers 4 to disengage from the fixing groove 33, achieving automatic unloading.

[0037] like Figures 5-7 As shown, in some embodiments, the clamping mechanism 3 further includes a slider 32, a limiting post 34, and a connecting sleeve 35. Specifically, the slider 32 is disposed at the bottom of the clamping plate 31 and forms a sliding fit structure with the slide rail 222. This design not only ensures that the clamping mechanism 3 can achieve smooth and linear movement along the slide rail 222.

[0038] In addition, the limiting post 34, as an important positioning element, is set in the fixing groove 33. The limiting post 34 is used to connect with the connecting hole on the tool pliers 4 to ensure the stability of the workpiece positioning.

[0039] It is particularly important to note that the height of the limiting post 34 is lower than the surface of the clamping plate 31. This design can effectively avoid interference problems during the grinding process.

[0040] Finally, the connecting sleeve 35, as a key component for power transmission, is firmly installed on the side of the clamping plate 31 at a designated position through welding. The connecting sleeve 35 is rigidly connected to the end of the telescopic rod 225. This connection method ensures the high efficiency of power transmission, thereby guaranteeing the stability and reliability of the entire processing.

[0041] like Figure 8 As shown, in some embodiments, the support frame 5 further includes a crossbar 51, a fixed bushing 52, and a strut 54. The crossbar 51 is located at the grinding station. When the bearing module 22 rotates to the grinding station, the rear side of the bearing module 22 abuts against the crossbar 51, which supports the bearing module 22 and prevents the bearing module 22 from being subjected to force and displaced during grinding.

[0042] In addition, the strut 54 is located at the rear of the support frame 5, serving to support the entire support frame 5. Specifically, the strut 54 adopts a 45-degree inclined design and is firmly welded and fixed to the key stress position at the rear of the support frame 5, which can effectively resist the lateral force generated during processing and significantly enhance the rigidity of the overall structure.

[0043] Specifically, the fixed bushing 52 is a metal sleeve, fixed at a specific mounting position on the support frame 5, and mates with the connecting shaft 21. Specifically, after the connecting shaft 21 passes through the central through hole of the fixed bushing 52, it achieves a reliable connection with the output end of the rotary motor, ensuring the stability of power transmission.

[0044] The bottom of the support frame 5 is connected to the collection mechanism 7 by bolts. This connection method not only ensures structural strength but also facilitates disassembly and maintenance. At the same time, it ensures that the metal debris generated during processing can smoothly enter the collection system along the designed guide channel, keeping the working environment clean.

[0045] like Figure 3 , Figure 5 and Figure 6 As shown, in some embodiments, the grinding mechanism 1 includes a control cabinet 11, a grinding wheel 12, and a baffle 13. The grinding wheel 12 is the core grinding component, and an annular baffle 13 is provided around it. The bottom of the baffle 13 is connected to the collection mechanism 7 to ensure that the metal chips and lubricant generated during the grinding process can automatically slide off under gravity and be efficiently collected and processed.

[0046] The control cabinet 11 serves as the control center of the entire grinding mechanism 1. It is reliably electrically connected to the servo drive motor of the grinding wheel 12 and the rotary motor of the rotating support frame 2, thereby enabling multi-level adjustment of the rotation speed of the grinding wheel 12 and precise control of the rotation angle of the rotating support frame 2, ensuring processing accuracy.

[0047] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0048] The embodiments have been described above, and such description is not restrictive. The figures shown are only one embodiment, and the actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit, such design should fall within the scope of protection.
