For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] like Figures 1 to 4 As shown, a fixture tooling on a horizontal tool magazine chain includes: a plurality of connecting plates 1 are arranged on the outer ring side of the chain, and two internal gears 2 meshing with the chain are arranged on the inner ring side of the chain;

[0034] A knife seat 11 is fixedly arranged on the connecting plate 1, a knife clamp 111 is fixedly arranged on the knife seat 11, and two knife claws 112 are arranged on the knife clamp 111;

[0035] Wherein, the chain is arranged in two layers along the vertical direction;

[0036] The connecting plate 1 and each section of the chain are arranged corresponding to each other;

[0037] The two internal gears 2 are arranged at the corresponding two ends and are arranged in two layers along the vertical direction;

[0038] The two knife claws 112 are fixedly mounted on the knife clamp 111 via a rotating shaft 113 , and the two knife claws 112 are correspondingly arranged to form a U-shaped clamping structure 114 .

[0039] When preparing to fix the chain, it is necessary to first place the fixture on both sides of the chain to ensure that the inner gear 2 on the fixture corresponds to the inner ring. Since there are two layers in the vertical direction, the inner gear 2 is also provided with two layers in the vertical direction to adapt to the double-layer chain structure. Then, the inner gear 2 is meshed with the inner ring of the chain through the operating mechanism, and a firm connection is formed between the fixture and the chain. The connecting plate 1 and each section of the chain are arranged corresponding to each other, so that the outer ring side of each section of the chain can be supported and fixed by the connecting plate 1. The tool holder 111 is fixed, and then the tool clamp 111 on the tool seat 11 starts to work. Two tool claws 112 are arranged on the tool clamp 111, and the two tool claws 112 are fixed to the tool clamp 111 through a rotating shaft 113. The two tool claws 112 are arranged correspondingly and form a U-shaped clamping structure 114. When the tool needs to be replaced or positioned, the operator can place the tool handle between the two tool claws 112 and adjust the position of the tool claws 112 to tightly clamp the tool handle. The tool is firmly fixed on the tool clamp 111, forming a stable connection with the chain.

[0040] The chain and the tool are doubly fixed by the fixture to ensure the relative position of the tool and the chain is stable, thereby improving accuracy and consistency; the design of the fixture makes the replacement and positioning of the tool simple and convenient, improving overall work efficiency; the fixture can adapt to chains of different specifications and lengths and different types of tools, and has strong versatility and flexibility.

[0041] In this embodiment, a positioning key 111A is fixedly provided at the center of the tool holder 111 .

[0042] When the operator places the tool on the tool holder 111 and prepares to fix it, the design of the positioning key 111A ensures that the tool can be aligned and fixed in the predetermined position when placed, and the operator can place the tool in the correct position with the guidance of the positioning key 111A. Once the tool is properly placed, the two claws 112 can tightly grasp the handle of the tool.

[0043] The presence of the positioning key 111A enables the tool to be quickly and accurately positioned at a predetermined position when placed, avoiding errors and uncertainties caused by manual adjustment and improving positioning accuracy and stability; the design of the positioning key 111A allows the operator to complete the placement and fixing of the tool more easily without the need for tedious manual adjustment, thereby simplifying the operation process and improving work efficiency.

[0044] In this embodiment, an opening and closing gripping plate 115 is fixedly provided on the knife holder 11 , and the opening and closing gripping plate 115 is correspondingly arranged directly below the U-shaped gripping structure 114 .

[0045] The opening and closing gripping plate 115 and the U-shaped gripping structure 114 work together to clamp the handle of the tool. When the tool is placed in the correct position, the opening and closing gripping plate 115 closes to fix the tool on the tool holder 11. The U-shaped gripping structure 114 formed by the two claws 112 is arranged directly above the opening and closing gripping plate 115. The two claws 112 clamp the handle of the tool to further fix it.

[0046] The dual fixing mechanism of the opening and closing gripping plate 115 and the U-shaped gripping structure 114 ensures the stability and reliability of the tool during the clamping process, and effectively prevents the tool from loosening or moving; the opening and closing gripping plate 115 can open and close to adapt to tools of different sizes, making the fixture tooling suitable for a variety of types of tools, improving its versatility and flexibility.

[0047] In this embodiment, an origin sensing block 3 is fixedly disposed at the bottom of each chain link.

[0048] During the processing or transportation process, the origin sensing block 3 is mainly used to provide position information of each section of the chain. For example, when the sensing system detects the origin sensing block 3, it will send a signal to the control system to inform the current number of sections or position of the chain. The control system will perform corresponding operations based on the received signal, such as adjusting the processing equipment parameters according to the chain position information. The control system can also control the movement speed or direction of the chain according to the signal of the origin sensing block 3.

[0049] The origin sensor block 3 provides real-time feedback of the chain position, which helps the control system optimize efficiency. In the event of a failure or maintenance, the chain troubleshooting and maintenance time can be shortened.

[0050] In this embodiment, the straight portion of the chain is provided with a nylon strip 4, the width of which is consistent with the width of the lower chain, and is clamped in the lower chain;

[0051] The nylon strip 4 limits the movement of the chain in the vertical direction.

[0052] When the chain is in operation, the nylon strip 4 mainly limits the movement of the chain in the vertical direction. By being clamped in the lower chain, the nylon strip 4 provides a vertical support and restriction for the chain.

[0053] The provision of the nylon strip 4 significantly enhances the vertical stability of the chain, helps to reduce chain displacement caused by vibration or external force, and ensures that the chain always maintains the correct position during transmission; since the nylon strip 4 restricts the vertical movement of the chain, the transmission of the tool on the chain can be more precise and stable, thereby improving the overall transmission accuracy.

[0054] In this embodiment, the material of the blade claw 112 is a high-strength alloy material that is wear-resistant and corrosion-resistant.

[0055] The wear-resistant and corrosion-resistant high-strength alloy material makes the knife claw 112 have excellent durability, and can maintain its stable performance during long-term use, reduce the replacement frequency due to wear or corrosion, and reduce maintenance costs; the high-strength alloy material not only ensures the mechanical strength of the knife claw 112, but also gives it better clamping stability and improves efficiency.

[0056] In this embodiment, a roller 116 is provided at the bottom of the knife seat 11, and a rolling strip 116A used in conjunction with the roller 116 is provided below;

[0057] The shape of the roller 116A is consistent with the shape of the chain.

[0058] The roller 116 disposed at the bottom of the knife seat 11 cooperates with the roller 116A below. When the chain needs to be moved or adjusted, the roller 116 and the roller 116A interact with each other to form a sliding mechanism.

[0059] The coordinated use of roller 116 and roller bar 116A makes the movement of the fixture smoother and more efficient. The rolling mechanism greatly reduces friction and increases the moving speed. The shape of roller bar 116A is consistent with the shape of the chain. Roller 116 can roll along the shape of the chain to maintain a stable motion trajectory, which helps to reduce deviation or shaking, enhance stability, reduce operating difficulty, and reduce wear.

[0060] As a preferred embodiment of the above, an inner guide groove 5 and an outer guide bar 6 are fixedly arranged on the inner ring side of the chain, the inner guide groove 5 is arranged parallel to the straight line portion of the upper chain, the outer guide bar 6 wraps the straight line portion of the upper chain, and forms a straight groove route with the inner guide groove 5;

[0061] The inner guide groove 5 and the outer guide bar 6 restrict the movement of the chain in the horizontal direction.

[0062] The inner guide groove 5 is fixedly arranged on the inner ring side of the chain and is parallel to the straight line portion of the upper chain. The outer guide bar 6 wraps the straight line portion of the upper chain and forms a straight groove route together with the inner guide groove 5. The straight groove route not only provides a clear path for the chain, but also limits the horizontal movement of the chain through its special structure. When the chain is running or subjected to external force, the inner guide groove 5 and the outer guide bar 6 will work together to prevent the chain from deflecting or sliding in the horizontal direction.

[0063] By controlling the movement trajectory of the chain, the inner guide groove 5 and the outer guide bar 6 reduce the friction and resistance of the chain during operation, thereby improving the transmission efficiency; due to the stabilizing effect of the inner guide groove 5 and the outer guide bar 6 on the chain, the wear and impact on the chain during operation will also be reduced accordingly, which helps to extend the service life of the chain and reduce maintenance costs.
