Description

Technical Field

[0001] This invention relates to the field of chain link preparation technology, specifically to an auxiliary device and system for processing flat chain links. Background Technology

[0002] Flat chain links are essential components in mining conveyor equipment, their function being to connect the ends of mining chains. For example... Figure 1 As shown, the commonly used flat connecting ring 9 includes a left half ring 91 and a right half ring 92. During the manufacturing process, specific assembly holes and positioning grooves, such as positioning anti-rotation grooves 93, need to be machined on the left half ring 91 and the right half ring 92.

[0003] Currently, when machining the flat connecting link 9, a universal three-jaw or four-jaw chuck built into the machine tool is typically used for clamping. However, the outer contour of the flat connecting link 9 is not a standard cylindrical surface and is composed of two half-rings joined together. The universal jaws cannot fully adapt to its shape, resulting in a small contact area and uneven clamping force distribution. During machining, it is subjected to large intermittent cutting forces, and the left half-ring 91 and right half-ring 92 are prone to slight slippage or high-frequency vibration within the fixture, making it difficult to guarantee the machining accuracy of the holes and slots, resulting in a low product yield. Summary of the Invention

[0004] In view of this, it is necessary to provide a flat chain link machining auxiliary device and machining system. The flat chain link machining auxiliary device, based on the structural design of the flat chain link, enables the flat chain link to be firmly fixed on the machine tool and resists the force generated by the cutting tool, ensuring the machining accuracy of holes and grooves and improving the product qualification rate.

[0005] A flat chain link processing auxiliary device includes: a mounting base configured to be mounted on a machine tool worktable, the mounting base having multiple through holes formed on its side; a first fixing component disposed on the mounting base, the first fixing component including a first base, a transmission member slidably disposed relative to the first base, and a tensioning member connected to the transmission member, the first base having a liquid cavity communicating with at least one through hole, the transmission member being partially disposed within the liquid cavity, liquid introduced into the through hole entering the liquid cavity to drive the transmission member to slide, thereby causing the tensioning member to move to a curved groove tensioned inside the flat chain link, so as to fix it relative to the mounting base; and a second fixing component disposed on the mounting base, the second fixing component including a second base, a driver disposed on the second base, and a clamping member connected to the driver, the driver communicating with at least another through hole, liquid introduced into the through hole driving the driver to move and rotate the clamping member, so as to press it against the upper surface of the flat chain link, so as to fix it relative to the mounting base.

[0006] Preferably, the two through holes are formed as a first through hole and a second through hole. The transmission member divides the liquid cavity into a first liquid cavity connected to the first through hole and a second liquid cavity connected to the second through hole. Liquid introduced into the first through hole enters the first liquid cavity and pushes the transmission member relative to the first base in a direction away from the first liquid cavity, and squeezes the liquid in the second liquid cavity out through the second through hole, thereby driving the tensioning member to tension and fix the flat connecting chain ring. Liquid introduced into the second through hole enters the second liquid cavity and pushes the transmission member relative to the first base in a direction toward the first liquid cavity, and squeezes the liquid in the first liquid cavity out through the first through hole, thereby driving the tensioning member to release the flat connecting chain ring.

[0007] Preferably, the first through hole and the second through hole extend horizontally, the upper part of the mounting base is provided with a first connecting hole communicating with the first through hole and a second connecting hole communicating with the second through hole, the bottom of the first base is provided with a first docking hole communicating with the first liquid cavity and a second docking hole communicating with the second liquid cavity, the first base is mounted on the top of the mounting base, the first docking hole is docked and communicated with the first connecting hole, and the second docking hole is docked and communicated with the second connecting hole.

[0008] Preferably, the first base also has a movable cavity formed inside, which is disposed on one side of the second liquid cavity and isolated from the second liquid cavity. The transmission member is partially located in the movable cavity to provide space for it to slide relative to the first base. The movable cavity extends to the upper surface of the first base so that the transmission member is connected to the tensioning member at that position.

[0009] Preferably, both the tensioning member and the transmission member are configured in pairs and correspond one-to-one. Driven by the liquid in the first liquid chamber, the two tensioning members move in opposite directions to press against the arc-shaped groove of the inner ring of the flat connecting chain ring to tension and fix the flat connecting chain ring. Driven by the liquid in the second liquid chamber, they move in opposite directions to disengage from the flat connecting chain ring. The tensioning member is formed as a columnar structure, and the curvature of its arc-shaped surface is the same as the curvature of the arc-shaped groove of the inner ring of the flat connecting chain ring so that the tensioning member can fit into the arc-shaped groove.

[0010] Preferably, one of the through holes is formed as a drain hole communicating with the liquid cavity to drain gas and residual liquid from the liquid cavity.

[0011] Preferably, the two through holes are formed as a third through hole and a fourth through hole. The driver is connected to the third through hole and the fourth through hole. The liquid entering the third through hole drives the driver to press the clamping member to the upper surface of the flat connecting chain ring. The liquid entering the fourth through hole drives the clamping member to release the flat connecting chain ring. The mounting base is provided with a third connecting hole connected to the third through hole and a fourth connecting hole connected to the fourth through hole. The bottom of the second base is provided with a third docking hole and a fourth docking hole connected to the driver. The second base is positioned above the mounting base. The third docking hole is connected to the third connecting hole, and the fourth docking hole is connected to the fourth connecting hole.

[0012] Preferably, the first base is horizontally inclined on the upper surface of the mounting base. The inclination angle is the same as the inclination angle of the positioning anti-rotation groove to be processed on the flat connecting link relative to the long axis of the flat connecting link. The inclination direction is opposite to the inclination direction of the positioning anti-rotation groove to be processed on the flat connecting link relative to the long axis of the flat connecting link, so that the cutting tool on the machine tool can cut out the positioning anti-rotation groove by moving along the extension direction parallel to one side of the mounting base.

[0013] Preferably, there are multiple first fixing components and second fixing components, with one first fixing component and two second fixing components forming a fixing group. The two second fixing components in each fixing group are located on opposite sides of one of the first fixing components in the fixing group, so that the opposite sides of a flat connecting chain ring are respectively pressed by the two second fixing components.

[0014] A machining system includes a machine tool and the aforementioned flat chain link machining auxiliary device, wherein the flat chain link machining auxiliary device is mounted on the machine tool.

[0015] The present invention employs the above-mentioned technical solution, and its beneficial effects are as follows: By setting a first fixing component and a second fixing component to fix the flat connecting chain ring, wherein the tensioning member of the first fixing component moves to be tensioned at the arc-shaped groove inside the flat connecting chain ring, and the pressing member of the second fixing component moves and rotates to press against the upper surface of the flat connecting chain ring, a multi-dimensional three-dimensional fixation of the flat connecting chain ring is achieved from inner ring tensioning and upper surface pressing. This dual fixing mechanism fully utilizes the structural features of the flat connecting chain ring, increases the contact area between the device and the flat connecting chain ring, thereby achieving high-stability fixation. In addition, the liquid in the through hole drives the transmission component of the first fixing component and the driver component of the second fixing component respectively to achieve hydraulic drive, which can provide stable and strong force, effectively resist the cutting force during the processing, avoid the slight slippage and vibration of the flat connecting chain ring, thereby significantly improving the processing accuracy of the hole and groove, and thus improving the product qualification rate.

Detailed Implementation

[0026] To more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0027] Please refer to Figures 1 to 9 This invention provides an auxiliary device for processing flat chain links, comprising: a mounting base 10 configured to be mounted on a machine tool worktable, wherein a plurality of through holes 11 are formed on the side of the mounting base 10; and a first fixing component 20 disposed on the mounting base 10, the first fixing component 20 including a first base 22, a transmission member 23 slidably disposed relative to the first base 22, and a tensioning member 21 connected to the transmission member 23, wherein a liquid cavity 221 communicating with at least one through hole 11 is formed inside the first base 22, and the transmission member 23 is partially disposed in the liquid cavity 221, wherein liquid introduced into the through hole 11 enters the liquid cavity. The drive transmission member 23 slides within 221, thereby moving the tensioning member 21 to the arc-shaped groove inside the flat connecting ring 9 to fix it relative to the mounting base 10; and the second fixing component 30 is disposed on the mounting base 10. The second fixing component 30 includes a second base 32, a driver 33 disposed on the second base 32, and a clamping member 31 connected to the driver 33. The driver 33 communicates with at least one other through hole 11. Liquid entering the through hole 11 drives the driver 33 to move and rotate the clamping member 31 to press it against the upper surface of the flat connecting ring 9 to fix it relative to the mounting base 10.

[0028] The multi-dimensional three-dimensional fixing mechanism, achieved by the tensioning element 21 of the first fixing component 20 for inner ring tensioning and the pressing element 31 of the second fixing component 30 for upper surface pressing, significantly increases the contact area between the device and the flat connecting ring 9. In actual machining workshops, the machining environment is often accompanied by severe vibration and intermittent heavy cutting forces. Traditional general-purpose grippers, due to their small contact area and lack of specific fit to the shape of the flat connecting ring 9, are prone to causing the flat connecting ring 9 to loosen. The flat connecting ring machining auxiliary device of the present invention fully utilizes the internal arc-shaped groove space of the flat connecting ring 9 for outward tensioning support, while simultaneously using the downward pressing fixation of the upper surface to form multi-directional constraints. This three-dimensional fixing can not only resist cutting forces in all directions and eliminate the micro-slippage and high-frequency vibration of the flat connecting ring 9 during machining, greatly improving the machining accuracy of holes and grooves, but also reduce tool wear during cutting and extend tool life, thereby solving the technical problem of low product qualification rate.

[0029] Furthermore, both the tensioning member 21 and the clamping member 31 are hydraulically driven. Specifically, the fluid within the through hole 11 drives the transmission member 23 of the first fixing component 20 and the driver 33 of the second fixing component 30, respectively. The hydraulic drive provides a stable and powerful force, thereby enabling automatic fixing. The fluid can be hydraulic oil.

[0030] Specifically, the machine tool can be a machining center. The flat connecting link 9 also includes a self-locking mechanism disposed between the left half-ring 91 and the right half-ring 92. Therefore, mounting holes and mounting slots adapted to the self-locking mechanism need to be opened between the left half-ring 91 and the right half-ring 92 for mounting the self-locking mechanism. In other words, the holes and slots to be machined on the flat connecting link 9 can also include mounting holes and mounting slots.

[0031] Please refer to Figure 2 , Figure 3 , Figure 6 and Figure 9 In some embodiments, the two through holes 11 are formed as a first through hole 111 and a second through hole 112. The transmission member 23 divides the liquid cavity 221 into a first liquid cavity 2211 connected to the first through hole 111 and a second liquid cavity 2212 connected to the second through hole 112. Liquid entering the first through hole 111 enters the first liquid cavity 2211 and pushes the transmission member 23 relative to the first base 22 in a direction away from the first liquid cavity 2211, and squeezes the liquid in the second liquid cavity 2212 out through the second through hole 112, thereby driving the tensioning member 21 to tension and fix the flat connecting ring 9. Liquid entering the second through hole 112 enters the second liquid cavity 2212 and pushes the transmission member 23 relative to the first base 22 in a direction toward the first liquid cavity 2211, and squeezes the liquid in the first liquid cavity 2211 out through the first through hole 111, thereby driving the tensioning member 21 to release the flat connecting ring 9.

[0032] The first fixing component 20, driven by bidirectional hydraulics, enables automatic tensioning and releasing of the tensioning element 21. When dealing with large-volume, continuous production of flat chain links 9, manual operation of the tensioning element 21 is not only time-consuming and labor-intensive, but also difficult to guarantee consistent tension each time. This invention utilizes a hydraulic system to provide a stable and quantifiable driving force, ensuring that each flat chain link 9 achieves consistent clamping stiffness, avoiding the risk of insufficient tension or damage to the flat chain link 9 due to human factors. Simultaneously, the bidirectional hydraulic circuit allows for smooth and rapid loading and unloading of the flat chain link 9, shortening non-processing auxiliary time and thus improving batch processing efficiency.

[0033] Please continue reading. Figure 2 , Figure 3 , Figure 6 and Figure 9In some embodiments, the first through hole 111 and the second through hole 112 extend horizontally. The upper part of the mounting base 10 is provided with a first connecting hole communicating with the first through hole 111 and a second connecting hole communicating with the second through hole 112. The bottom of the first base 22 is provided with a first docking hole 222 communicating with the first liquid cavity 2211 and a second docking hole 223 communicating with the second liquid cavity 2212. The first base 22 is mounted above the mounting base 10. The first docking hole 222 is docked and communicated with the first connecting hole, and the second docking hole 223 is docked and communicated with the second connecting hole.

[0034] The mounting base 10 integrates a complex liquid flow path, achieving modular and seamless flow path connectivity through a hole-to-hole design. The first docking hole 222 and the second docking hole 223 of the first base 22 are respectively positioned to align with the first and second connecting holes of the mounting base 10. This ensures that after the first base 22 is installed on the mounting base 10, the first docking hole 222 can directly align with the first connecting hole for connection, and the second docking hole 223 can directly align with the second connecting hole for connection. This modular docking design facilitates the maintenance and replacement of the first fixing component 20, reducing equipment maintenance costs. Furthermore, this built-in oil circuit design eliminates safety hazards associated with external pipelines, such as pipeline damage and leakage, and also prevents interference from pipeline installation on the movement of the tensioning member 21 and the clamping member 31, improving the service life and operational reliability of the device under complex operating conditions.

[0035] Specifically, such as Figure 6 As shown, a second docking hole 223 is provided in each of the two second liquid chambers 2212. Figure 6 At a location not shown inside the second base 32, the two second docking holes 223 converge downwards to form a single second docking hole 223, which extends to the bottom of the second base 32. This forms a "Y"-shaped liquid flow channel inside the second docking hole 223. The amount of liquid entering from the second docking hole 223 at the bottom of the second base 32 is the same as the amount flowing into the two second liquid chambers 2212, thereby enabling the two tensioning members 21 to move synchronously in opposite directions. The second docking hole 223 at the bottom of the second base 32 corresponds to the second connecting hole of the mounting base 10.

[0036] Please refer to Figure 6 In some embodiments, the first base 22 also has a movable cavity 224 disposed on one side of the second liquid cavity 2212 and isolated from the second liquid cavity 2212. The transmission member 23 is partially located in the movable cavity 224 to provide space for it to slide relative to the first base 22 through the movable cavity 224. The movable cavity 224 extends to the upper surface of the first base 22 so that the transmission member 23 is connected to the tensioner 21 at this position.

[0037] The moving cavity 224 provides sufficient sliding space for the transmission component 23. Furthermore, the moving cavity 224 physically isolates the hydraulic working area formed in the liquid cavity 221 from other liquid-free working areas, preventing impurities such as coolant, iron filings, and dust from entering the liquid during the processing, ensuring the cleanliness of the liquid, thereby maintaining the long-term stability of the liquid drive. This ensures that the tensioning component 21 can move smoothly to tension and release the flat connecting chain ring 9, and also prevents the transmission component 23 from wearing due to impurities in the liquid.

[0038] Specifically, the transmission component 23 includes a sealing section 231, a sliding section 232, and a connecting section 233 connected in sequence. The sealing section 231 is slidably sealed to the wall of the liquid chamber 221 to isolate the first liquid chamber 2211 and the second liquid chamber 2212. One end of the sliding section 232 is connected to the sealing section 231, and the other end is connected to the connecting section 233. The sliding section 232 and the connecting section 233 are perpendicular, i.e., the sliding section 232 is horizontally arranged, and the connecting section 233 is vertically arranged. The connecting section 233 is connected to the tensioning component 21. The first fixing component 20 also includes a sealing component 25 disposed in the moving cavity 224. The sealing component 25 includes a flange and a sealing ring fixed at the junction of the moving cavity 224 and the liquid chamber 221 by the flange. The sealing component 25 seals and isolates the liquid chamber 221 from the moving cavity 224 and is sleeved on the outer periphery of the sliding section 232, and is movably sealed to the sliding section 232. Figure 7 As shown, the movable cavity 224 extends upward to the upper surface of the first base 22, forming an opening. Next to this opening, a notch 225 is formed that runs through the movable cavity 224 for installing the sealing element 25 through the notch 225. The first base 22 is formed into two halves along its length, for welding and fixing the two halves of the first base 22 after the transmission element 23 is installed into the liquid cavity 221 and the movable cavity 224.

[0039] like Figure 4 and Figure 5As shown, the first fixing component 20 also includes a slider 24 that is slidably connected to the first base 22 in a sealed manner. A rubber strip is provided at the contact position between the slider 24 and the first base 22 to achieve a sealed sliding fit between the slider 24 and the first base 22. The slider 24 covers the upper part of the moving cavity 224, forming a closed space within the moving cavity 224. During the sliding process relative to the first base 22, the slider 24 can keep impurities such as coolant, iron filings, and dust above the first base 22 isolated outside the slider 24, i.e., outside the opening above the moving cavity 224, preventing impurities from entering the moving cavity 224 from above. This avoids obstruction or wear of the connecting section 233, thus ensuring smooth movement of the tensioning member 21. The slider 24 is provided with a connecting hole, and the tensioning member 21 is sealed and connected to the connecting hole, protruding upwards from the slider 24. The slider 24 includes a sliding part 241 that is slidably connected to the first base 22 and a mounting part 242 that is detachably connected to the upper part of the sliding part 241. When the mounting part 242 is worn and needs to be replaced, the mounting part 242 can be removed and replaced, which is convenient to operate.

[0040] Please refer to Figures 4 to 6 In some embodiments, tensioning member 21 and transmission member 23 are both provided in pairs and correspond one to one. The two tensioning members 21 move in opposite directions under the drive of the liquid in the first liquid chamber 2211 to press against the arc-shaped groove of the inner ring of the flat connecting ring 9 to tension and fix the flat connecting ring 9. Under the drive of the liquid in the second liquid chamber 2212, they move in the direction of approaching each other to disengage from the flat connecting ring 9. The tensioning member 21 is formed as a columnar structure, and the curvature of its arc surface is the same as the curvature of the arc-shaped groove of the inner ring of the flat connecting ring 9 so that the tensioning member 21 can fit into the arc-shaped groove.

[0041] like Figure 1 As shown, the inner ring of the flat connecting ring 9 has two arc-shaped grooves, located on the left half-ring 91 and the right half-ring 92 respectively. Corresponding to this shape of the flat connecting ring 9, two tensioning members 21 are provided. The two tensioning members 21 abut against the two arc-shaped grooves respectively, generating tension on the left half-ring 91 and the right half-ring 92. The left half-ring 91 and the right half-ring 92, under the action of their own locking teeth, generate an interaction force to achieve mutual tension, thus securing them firmly relative to the machine tool. Furthermore, the design of the double tensioning members 21 moving in opposite directions enables symmetrical and uniform tensioning of the inner ring of the flat connecting ring 9. In addition, the arc-shaped surface of the columnar structure of the tensioning member 21 contacts and fits against the arc-shaped groove surface of the arc-shaped groove, which not only maximizes the tension strength but also avoids indentation or damage to the surface of the inner ring of the flat connecting ring 9 due to local stress concentration.

[0042] Specifically, the two transmission components 23 can isolate two second liquid chambers 2212, and the liquid entering the two second liquid chambers 2212 respectively pushes the two transmission components 23 to move; a common first liquid chamber 2211 is formed between the sealing sections 231 of the two transmission components 23, and the liquid entering the first liquid chamber 2211 simultaneously pushes the two transmission components 23 to move; two moving chambers 224 are also provided, each corresponding to one of the two transmission components 23; two sealing components 25 are also provided, each sealing and fixing the connection between the two second liquid chambers 2212 and the corresponding two moving chambers 224; two sliders 24 are also provided, each corresponding to one of the two tensioning components 21.

[0043] Please refer to Figure 9 In some embodiments, one of the through holes 11 is formed as a discharge hole 113 communicating with the liquid chamber 221 to discharge gas and residual liquid in the liquid chamber 221.

[0044] After each use, liquid may remain in the liquid chamber 221 or gas may enter. The discharge hole 113 is designed to discharge these liquids and gases, ensuring that the liquid chamber 221 is filled with liquid during use. This ensures that there is no residual liquid or gas occupying space in the first liquid chamber 2211 and the second liquid chamber 2212, thereby ensuring that the tensioning member 21 can move into place quickly and that sufficient and reliable tension is generated each time.

[0045] Please refer to Figure 2 , Figure 3 , Figure 8 and Figure 9 In some embodiments, two of the through holes 11 are formed as a third through hole 114 and a fourth through hole 115. The driver 33 is connected to the third through hole 114 and the fourth through hole 115. The liquid driving the driver 33 into the third through hole 114 drives the clamping member 31 to press against the upper surface of the flat connecting ring 9. The liquid driving the driver 33 into the fourth through hole 115 drives the clamping member 31 to release the flat connecting ring 9. The mounting base 10 is provided with a third connecting hole connected to the third through hole 114 and a fourth connecting hole connected to the fourth through hole 115. The bottom of the second base 32 is provided with a third docking hole 321 and a fourth docking hole 322 connected to the driver 33. The second base 32 is disposed above the mounting base 10. The third docking hole 321 is docked and connected to the third connecting hole, and the fourth docking hole 322 is docked and connected to the fourth connecting hole.

[0046] The clamping member 31 is rotated and raised / lowered by the driver 33 to achieve clamping. During the loading and unloading of the flat connecting link 9, the clamping member 31 can automatically rise and rotate to one side, making unobstructed space above the flat connecting link 9 for easy placement by the operator. This allows the operator to place the flat connecting link 9 on the position fitted with the two tensioning members 21. During the clamping stage, the driver 33 drives the clamping member 31 to rotate directly above the flat connecting link 9 and press down. The clamping force of the clamping member 31 above the flat connecting link 9 and the horizontal tensioning force of the tensioning member 21 on the inner ring of the flat connecting link 9 work together to achieve multi-directional locking of the flat connecting link 9, preventing any tendency of the flat connecting link 9 to flip or tilt under the action of cutting force.

[0047] Similar to the first base 22 of the first fixing component 20, the second base 32 of the second fixing component 30 also achieves modular seamless flow path communication through a hole-to-hole method. The third docking hole 321 and the fourth docking hole 322 of the second base 32 are respectively positioned to correspond to the third connecting hole and the fourth connecting hole of the mounting base 10. This allows the third docking hole 321 to be directly aligned with the third connecting hole and the fourth docking hole 322 to be directly aligned with the fourth connecting hole after the second base 32 is installed on the mounting base 10. The modular docking design facilitates the maintenance and replacement of the second fixing component 30 and reduces the maintenance cost of the equipment. The flow path inside the driver 33 is connected to the second base 32, and the second base 32 is connected to the third through hole 114 and the fourth through hole 115 on the mounting base 10. The second base 32 is also used to raise the driver 33 and the clamping member 31, so that the distance between the clamping member 31 and the upper surface of the slider 24 when the clamping member 31 is at its highest position is greater than the thickness of the flat connecting ring 9, so as to avoid the clamping member 31 contacting the flat connecting ring 9 during rotation, thereby avoiding damage to the flat connecting ring 9.

[0048] Specifically, the clamping member 31 has a plate-like structure, and the driver 33 and the clamping member 31 can be composed of a rotary hydraulic cylinder.

[0049] Please refer to Figure 2 and Figure 3 In some embodiments, the first base 22 is horizontally inclined on the upper surface of the mounting base 10. The inclination angle is the same as the inclination angle of the positioning anti-rotation groove 93 to be processed on the flat connecting link 9 relative to the long axis of the flat connecting link 9. The inclination direction is opposite to the inclination direction of the positioning anti-rotation groove 93 to be processed on the flat connecting link 9 relative to the long axis of the flat connecting link 9, so that the cutting tool on the machine tool can cut out the positioning anti-rotation groove 93 by moving along the extension direction parallel to one side of the mounting base 10.

[0050] The standard feed axes of the cutting tools on the machine tool are generally the transverse and longitudinal axes along the horizontal plane. Alternatively, it is simplest to set the feed path of the cutting tool to the transverse and longitudinal axes along the horizontal plane. However, the positioning anti-rotation groove 93 of the flat connecting link 9 is a groove that is inclined on the horizontal plane. If the extension direction of the cutting tool feed path is set along the setting direction of the positioning anti-rotation groove 93, the operation is more complicated and prone to errors, reducing the forming accuracy of the positioning anti-rotation groove 93. Therefore, the first base 22 is directly inclined on the mounting base 10, and the inclined positioning anti-rotation groove 93 to be processed is directly aligned with the standard feed axes of the cutting tool on the machine tool. By implementing angle compensation at the physical level, the machine tool can complete the machining of the angle groove with only the simplest single-axis linear feed. In other words, the machining of the positioning anti-rotation groove 93 of the flat link 9 can be achieved using a simple machine tool with a standard feed axis. This not only reduces the dependence on higher-end multi-axis CNC machine tools and reduces equipment investment costs, but also benefits from the fast feed speed of the single-axis cutting of the simple machine tool, thereby improving the machining efficiency of the positioning anti-rotation groove 93.

[0051] Please continue reading. Figure 2 and Figure 3 In some embodiments, a plurality of first fixing components 20 and second fixing components 30 are provided, and one first fixing component 20 and two second fixing components 30 form a fixing group. The two second fixing components 30 in each fixing group are located on opposite sides of one first fixing component 20 in the fixing group, so that the opposite sides of a flat connecting chain ring 9 are respectively pressed by two second fixing components 30.

[0052] Through the above configuration, firstly, a single fixing group can achieve a three-point stable clamping of a flat connecting link 9, namely, a first fixing component 20 with bidirectional tension in the central inner ring and two second fixing components 30 on both sides with downward pressure, resulting in balanced force distribution. Secondly, multiple fixing groups can be arranged on the same mounting base 10 to form an array structure, enabling the clamping of multiple flat connecting links 9 at once. The machine tool can continuously feed to complete the machining of the entire row of flat connecting links 9, reducing the time cost of machine tool return to the reference point and manual loading and unloading, and enabling large-scale, assembly-line-style high-efficiency production.

[0053] The specific usage method of this device is as follows:

[0054] Fix the mounting base 10 on the machine tool workbench, and connect the external hydraulic source to the four through holes 11 on the side of the mounting base 10: the first through hole 111, the second through hole 112, the third through hole 114 and the fourth through hole 115, and connect the discharge pipe to the discharge hole 113.

[0055] In the initial state, the two tensioning members 21 of the first fixing component 20 are in a contracted state that is close to each other, and the clamping member 31 of the second fixing component 30 is in a rotating avoidance state. The assembled left half ring 91 and right half ring 92 of the flat connecting ring 9 to be processed are placed above the slider 24, so that the two tensioning members 21 pass through the inner ring of the flat connecting ring 9.

[0056] High-pressure liquid is introduced into the first through hole 111 through an external liquid source. The liquid enters the first liquid chamber 2211, which pushes the two transmission components 23 to slide and drives the two tensioning components 21 to move in opposite directions until their arc-shaped surfaces are tightly attached to the arc-shaped groove of the inner ring of the flat connecting chain ring 9.

[0057] High-pressure liquid is introduced into the third through hole 114 through an external liquid source. The liquid-driven actuator 33 is activated, causing the clamping member 31 to rotate above the flat connecting ring 9 and then press down on the upper surface of the flat connecting ring 9.

[0058] The cutting tool of the machine tool is used to machine the holes and grooves that need to be machined on the flat connecting link 9;

[0059] After processing, liquid is introduced into the fourth through hole 115 through an external liquid source. The driver 33 drives the clamping member 31 to rise vertically and rotate to avoid it. Liquid is introduced into the second through hole 112 through an external liquid source. The liquid enters the second liquid chamber 2212, pushes the two transmission members 23 to slide, and drives the two tensioning members 21 to move in a direction that approaches each other until they disengage from the flat connecting chain ring 9. At the same time, the liquid in the first liquid chamber 2211 is squeezed out and discharged from the first through hole 111.

[0060] Remove the finished flat connecting link 9 from the device. Processing complete.

[0061] This invention also provides a processing system, including a machine tool and the aforementioned flat chain link processing auxiliary device, wherein the flat chain link processing auxiliary device is mounted on the machine tool.
