Description

Technical Field

[0001] The utility model relates to the technical field of guide rails, in particular to a guide rail grounding mechanism with high stability. Background Art

[0002] Guide rails are an important component of machinery and equipment, and are commonly found in CNC machine tools, plastic machines and other machinery and equipment. Guide rails mainly play a role in positioning and guiding mechanical movement to ensure the accuracy and stability of mechanical equipment. Since the function of guide rails is to position and guide, when the machinery and equipment is in motion, friction, wear and static electricity are likely to occur. These problems may affect the accuracy and stability of the machine, and grounding can effectively avoid the occurrence of these problems, thereby ensuring the stability and safety of the machinery and equipment.

[0003] At present, the guide rail is generally grounded directly, that is, the guide rail is directly connected to the ground wire to conduct static electricity and heat into the ground. The length of the ground wire is generally fixed, which makes the ground wire too long and easy to be messy. If it is too short, another wire needs to be connected, which leads to inconvenience.

[0004] Therefore, how to design a rail grounding mechanism with high stability has become a problem that we currently need to solve. Utility Model Content

[0027] like Figure 1-4As shown, the utility model provides a technical solution: a guide rail grounding mechanism with high stability, comprising a guide rail 1 and a grounding wire 4 connected to the side thereof, a bolt and nut assembly 2 is installed below the side of the guide rail 1, the bolt and nut assembly 2 comprises a bolt and a nut, a connecting piece 3 is connected to the head end of the grounding wire 4, the bolt and the connecting piece 3 are interlaced, the nut is threadedly connected to the outside of the bolt and is tightly attached to the connecting piece 3, by plugging the connecting piece 3 with the bolt of the guide rail 1, and then sleeved on the outside of the bolt and pressing the connecting piece 3, the grounding wire 4 can be connected to the guide rail 1, and the connection method has high stability and is not easy to be separated;

[0028] The grounding wire 4 is externally movable and penetrates the wire box 5. The left side of the wire box 5 is rotatably connected with the second shaft 501. The wire wheel 503 is fixed to the outside of the second shaft 501. A driven gear 502 is fixed to the outside of the second shaft 501 and located above the wire wheel 503. A clockwork spring is installed outside the second shaft 501 and located below the wire wheel 503. The right side of the driven gear 502 is connected to the rotating component 6 for transmission. The right side of the rotating component 6 is provided with a limit component 7 that is clamped therewith. The rotating component 6 includes a knob 601, a shaft 1 602 and a driving gear 603. The shaft 1 602 is rotatably connected to the middle of the upper end of the wire box 5. The driving gear 603 is fixed to the lower end of the shaft 1 602. The upper end of the shaft 1 602 penetrates the wire box 5 and is fixedly connected to the knob 601. The driving gear 6 03 is meshed and connected with the driven gear 502. By storing the grounding wire 4 outside the reel 503 of the wire box 5, when the grounding wire 4 needs to be lengthened, one end of the grounding wire 4 can be directly pulled to unwind the grounding wire 4 from the outside of the reel 503, thereby increasing the length of the grounding wire 4. When the grounding wire 4 needs to be shorter, by turning the knob 601, the knob 601 drives the shaft 1 602 to rotate, the shaft 1 602 drives the driving gear 603 to rotate, the driving gear 603 drives the driven gear 502 to rotate, the driven gear 502 drives the shaft 2 501 to rotate, and the shaft 2 501 drives the reel 503 to rotate and rewind the grounding wire 4, thereby avoiding the problem of the grounding wire 4 being too long and complicated, and the grounding wire 4 being too short and needing to be connected.

[0029] The limiting assembly 7 includes a slide 701, a T-shaped slider 702, a large spring 703, a tooth block seat 708 and a tooth block 709. The slide 701 is fixed to the upper end of the wire box 5, and the T-shaped slider 702 is slidably connected to the inside of the slide 701. A tooth block 709 is fixed to the side of the lower part of the T-shaped slider 702 close to the driving gear 603. The tooth block 709 is meshed with the driving gear 603. The upper part of the T-shaped slider 702 is horizontally arranged above the slide 701, and the inner wall of the slide 701 Both the front and rear ends are provided with a card slot 707, both the front and rear ends of the T-shaped slider 702 are provided with a side slot 704, a card bead 706 is slidably connected inside the side slot 704, a small spring 705 is connected between the card bead 706 and the bottom of the side slot 704, the card bead 706 is plugged into the card slot 707, a large spring 703 is connected between the right end of the T-shaped slider 702 and the right end of the inner wall of the slide slot 701, and the card bead 706 of the T-shaped slider 702 is usually held in place by the elastic force of the small spring 705. When the tooth block 709 is in meshing engagement with the driving gear 603, the T-shaped slide block 702 is pushed rightward to continue squeezing the large spring 703. At this time, the card bead 706 is squeezed by the inner wall of the card slot 707 to move into the side groove 704. At this time, the card bead 706 squeezes the small spring 705, and then the T-shaped slide block 702 is released, and the large spring 703 recovers quickly, thereby driving the T-shaped slide block 702 to move left quickly. At this time, the T-shaped slide block 702 drives the tooth block seat 708 to move left quickly, so that the tooth block seat 708 drives the tooth block 709 to mesh and engage with the driving gear 603, thus preventing the driving gear 603 from rotating, making it impossible for the driving gear 603 to drive the driven gear 502 to rotate. Therefore, the line wheel 503 is limited to prevent the grounding wire 4 from being wound and unwound from the outside of the line wheel 503 due to non-human reasons.

[0030] The working process of the utility model is as follows: by plugging the connecting piece 3 into the bolt of the guide rail 1, and then sleeve the nut on the outside of the bolt and compress the connecting piece 3, the grounding wire 4 can be connected to the guide rail 1. Then, when the grounding wire 4 needs to be lengthened, the T-shaped slider 702 is first pushed to the right to squeeze the large spring 703, so that the T-shaped slider 702 drives the tooth block 709 to move away from the active gear 603 and no longer meshes with the active gear 603. In this way, after the card bead 706 corresponds to the card slot 707, the small spring 705 in a compressed state will bounce the card bead 706 and plug it into the card slot 707, so that the T-shaped slider 702 is limited, and then one end of the grounding wire 4 is directly pulled, so that the grounding wire 4 can be unwound from the outside of the wire wheel 503, thereby achieving the effect of increasing the length of the grounding wire 4. When the grounding wire 4 needs to be shorter, the knob 601 is turned, and the knob 601 drives the rotating shaft 1 602 to rotate, and the rotating shaft 1 602 drives the active The gear 603 rotates, the active gear 603 drives the driven gear 502 to rotate, the driven gear 502 drives the rotating shaft 2 501 to rotate, and the rotating shaft 2 501 drives the wire wheel 503 to rotate and rewind the grounding wire 4. After the grounding wire 4 is adjusted to a suitable length, the T-shaped slide block 702 can be pushed to the right to continue to squeeze the large spring 703. At this time, the card bead 706 is squeezed by the inner wall of the card slot 707 to move into the side slot 704, and then the T-shaped slide block 702 is released, and the large spring 703 recovers quickly, and drives the T-shaped slide block 702 to move left quickly. At this time, the T-shaped slide block 702 drives the tooth block seat 708 to move left quickly, so that the tooth block seat 708 drives the tooth block 709 to mesh with the active gear 603. In this way, the active gear 603 can be prevented from rotating, so that the active gear 603 cannot drive the driven gear 502 to rotate, so the wire wheel 503 is limited to prevent the grounding wire 4 from being wound and unwound from the outside of the wire wheel 503 due to non-human reasons.
