Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of door lock pull wire production tooling, and in particular relates to a door lock pull wire cutting production tooling. Background Technology
[0002] Electric soft-close doors are a common comfort and safety feature in luxury cars. When the door is not properly closed, it will automatically close until it is completely shut. When electricity is applied, a magnetic force is generated, and the door closes. When the power is cut off, the magnetic force disappears, and the door opens. The door lock of this type of door usually contains a door lock cable, which needs to be cut off during production using a cutting tool.
[0003] Although there are various cutting production toolings available today, some problems still exist. For example, most current cutting production toolings use two symmetrically arranged cutting tools to cut the wire during operation. However, these two tools require two sets of drive mechanisms (such as cylinders) to drive and control them. During the movement of the cylinders, it is impossible to guarantee that their extension and retraction strokes are completely consistent. This can lead to the wire being skewed due to changes in the extension and retraction stroke of one of the tools, resulting in inaccurate cutting lengths and a certain degree of deviation. Utility Model Content
[0004] This utility model provides a production fixture for cutting door lock pull cords, which aims to solve the problem that the cutters on both sides of the current pull cord cutting fixture cannot be accurately synchronized.
[0005] This utility model is implemented as follows: a door lock pull cord cutting production fixture includes: a base, a support, a slider, a cutting tool, a crimping mechanism, and a linkage unit. The support is fixed to one side of the base and has an installation cavity inside the base. The support has a slot that communicates with the installation cavity. Two sliders are symmetrically arranged and slidably engaged in the slot of the support. The cutting tool is fixed to the side of two adjacent sliders that are close to each other. The crimping mechanism is located on one side of the support. The linkage unit is located inside the installation cavity of the base.
[0006] The linkage unit includes a limiting sleeve, a transmission rod, a linkage gear, a docking seat, and a synchronous drive mechanism. The limiting sleeve is fixed to one side of one of the sliders, the transmission rod is fixed to one side of the other slider, and the transmission rod passes through the slider and is coaxially slidably connected inside the limiting sleeve. The length of the transmission rod is greater than that of the limiting sleeve. The linkage gear is rotatably connected to the mounting cavity of the base. The docking seat is fixed on the linkage gear and is eccentrically set. The synchronous drive mechanism is set on the linkage gear.
[0007] Preferably, the synchronous drive mechanism includes a driving rod, a first fixed seat, a driven rod, and a second fixed seat. The first fixed seat and the second fixed seat are respectively fixed to the end of the limiting sleeve and the transmission rod away from the slider. One end of the driving rod and the driven rod are rotatably connected to each other, and their connection point is rotatably connected to the docking seat. The other end of the driving rod is rotatably connected to the first fixed seat, and the other end of the driven rod is rotatably connected to the second fixed seat.
[0008] Preferably, a servo motor is fixed to the bottom of the base, and the output shaft of the servo motor is coaxially fixed at the center of the linkage gear.
[0009] Preferably, the linkage gear, driving rod, and driven rod are combined to form an integral structure, and two sets are symmetrically arranged in the mounting cavity of the base, with adjacent linkage gears meshing with each other, and adjacent sets of driving rods and driven rods forming a rhomboid structure.
[0010] Preferably, a clamping plate is provided on one side of the slider, and multiple clamping plates are provided at equal intervals on the slider, with the clamping plates on two adjacent sliders being staggered.
[0011] Preferably, a rectangular cavity is provided on one side of the slider, the clamping plate is slidably engaged in the rectangular cavity, and a spring is fixed inside the rectangular cavity, with one end of the spring abutting against the clamping plate.
[0012] Compared with the prior art, the embodiments of this application have the following main advantages:
[0013] In this solution, a linkage unit is set up. Through the synchronous drive mechanism in the linkage unit, the linkage gear drives the docking seat to move eccentrically during rotation. The docking seat drives the driving rod and the driven rod to move synchronously, which in turn drives the limit sleeve and the transmission rod to move synchronously in opposite directions. This allows the two adjacent sliders and the cutting blade to move synchronously in opposite directions, achieving a precise cutting effect on the door lock cable. This avoids the situation where the two adjacent cutting blades cannot move synchronously, causing the cable to be skewed when in contact with the cable, resulting in an inaccurate cutting length.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0021] This utility model embodiment provides a production tooling for cutting door lock pull cords, such as... Figures 1-4 As shown, it includes: a base 1, a support 2, a slider 3, a cutting tool 4, a sprue mechanism 5, and a linkage unit 6. The support 2 is fixed to one side of the base 1 and has an installation cavity inside the base 1. The support 2 has a slot that communicates with the installation cavity. The slider 3 is slidably engaged in the slot of the support 2, and two sliders are symmetrically arranged. The cutting tool 4 is fixed on the side of two adjacent sliders 3 that are close to each other. The sprue mechanism 5 is located on one side of the support 2. The linkage unit 6 is located inside the installation cavity of the base 1.
[0022] The linkage unit 6 includes a limiting sleeve 61, a transmission rod 62, a linkage gear 63, a docking seat 64, and a synchronous drive mechanism. The limiting sleeve 61 is fixed to one side of one of the sliders 3, the transmission rod 62 is fixed to one side of the other slider 3, and the transmission rod 62 passes through the slider 3 and is slidably connected to the limiting sleeve 61 on the same axis. The length of the transmission rod 62 is greater than that of the limiting sleeve 61. The linkage gear 63 is rotatably connected to the mounting cavity of the base 1. The docking seat 64 is fixed on the linkage gear 63 and is eccentrically set. The synchronous drive mechanism is set on the linkage gear 63. A servo motor 69 is fixed at the bottom of the base 1. The output shaft of the servo motor 69 is coaxially fixed at the center of the linkage gear 63.
[0023] The synchronous drive mechanism includes a driving rod 65, a first fixed seat 66, a driven rod 67, and a second fixed seat 68. The first fixed seat 66 and the second fixed seat 68 are respectively fixed to the end of the limiting sleeve 61 and the transmission rod 62 away from the slider 3. One end of the driving rod 65 and the driven rod 67 are rotatably connected to each other, and their connection point is rotatably connected to the docking seat 64. The other end of the driving rod 65 is rotatably connected to the first fixed seat 66, and the other end of the driven rod 67 is rotatably connected to the second fixed seat 68.
[0024] It should be noted that existing cutting production fixtures mostly use two symmetrically arranged cutting tools to cut the pull wire during operation. However, these two tools require two sets of drive mechanisms, such as cylinders, for drive control. During the movement of the cylinders, it is impossible to guarantee that their extension and retraction strokes are completely consistent. This can lead to the pull wire being skewed due to the change in the extension and retraction stroke of one of the tools, resulting in inaccurate cutting lengths and a certain degree of deviation. To solve this problem, this solution sets up a linkage unit 6. Through the synchronous drive mechanism in the linkage unit 6, the linkage gear 63 drives the docking seat 64 to eccentrically link during rotation. The docking seat 64 then drives the driving rod 65 and the driven rod 67 to move synchronously, which in turn drives the limiting sleeve 61 and the transmission rod 62 to move synchronously in the opposite direction. This allows the two adjacent sliders 3 and the cutting tools 4 to move synchronously in opposite directions, achieving a precise cutting effect on the door lock pull wire. This avoids the situation where the pull wire is skewed when it comes into contact with the two adjacent cutting tools 4 due to a lack of synchronous linkage, resulting in inaccurate cutting lengths.
[0025] Specifically, in this embodiment, the solution mainly includes a base 1, a support 2, a slider 3, a cutting tool 4, a rhinestone mechanism 5, a linkage unit 6, and a clamping plate 7. In use, the door lock cable is first placed at a predetermined position on the support 2, and then the servo motor 69 is started. The servo motor 69 drives the linkage gear 63 to rotate, and another linkage gear 63 meshes and links. At this time, the docking seat 64 is eccentrically linked on the linkage gear 63, and drives the limiting sleeve 61 and the transmission rod 62 to link in opposite directions through the driving rod 65 and the driven rod 67, thereby making the two adjacent sliders 3 link in opposite directions. The cable is cut off by the cutting tool 4. After cutting, the cut end of the cable is rhinestoned by the rhinestone mechanism 5.
[0026] In a further preferred embodiment of this utility model, such as Figures 1-4 As shown, a clamping plate 7 is provided on one side of the slider 3. Multiple clamping plates 7 are provided at equal intervals on the slider 3, and the clamping plates 7 on two adjacent sliders 3 are staggered.
[0027] In this embodiment, the cable is clamped and locked by the clamping plate 7 to prevent the cable from shaking when it is cut.
[0028] In a further preferred embodiment of this utility model, such as Figures 1-4 As shown, a rectangular cavity is provided on one side of the slider 3, the clamping plate 7 is slidably engaged in the rectangular cavity, and a spring is fixed inside the rectangular cavity, with one end of the spring abutting against the clamping plate 7.
[0029] In this embodiment, the sliding clamping plate 7 can move along with the slider 3, so that while clamping and fixing the wire, the clamping plate 7 can also avoid limiting the two adjacent sliders 3, so that the two adjacent cutting tools 4 can smoothly connect and cut the wire.
