Description

Technical Field

[0001] The utility model relates to the technical field of mattress processing, in particular to a fixing device for the frame interface. Background Art

[0002] Spring mattresses have become the current mainstream filled mattresses because the distribution of the supporting force on the human body is relatively uniform, which can not only play a sufficient supporting role but also ensure a reasonable physiological curvature of the spine. At present, the main materials for making spring mattresses are frames and spring cores. Among them, when assembling the frame, the steel wire needs to be bent into a frame shape and then the two free ends of the steel wire are pressed and fixed by a sleeve to form the required frame. In this process, how to accurately insert the steel wire into the sleeve and press and fix the connection is an urgent problem to be solved in the automatic assembly of the frame. Summary of the Utility Model

[0003] To overcome the above disadvantages, the purpose of the utility model is to provide a fixing device for the frame interface, which realizes the accurate insertion of the steel wire into the sleeve and the press and fix connection through mechanical cooperation, thereby facilitating the automatic assembly production of the frame.

[0004] To achieve the above purpose, the technical scheme adopted by the utility model is: a fixing device for the frame interface, including

[0005] An assembly platform, on which there is a positioning groove for accommodating the sleeve, and wire through holes communicating with the positioning groove are symmetrically arranged at both ends of the positioning groove in the left-right direction;

[0006] A wire moving mechanism, located on one side of the assembly platform, which includes a moving substrate that moves towards or away from the assembly platform under the action of a driving part, and two wire clamping parts that can move towards or away from each other in the left-right direction are arranged on the moving substrate, and the wire clamping parts are used to clamp the end of the wire;

[0007] A sleeve moving mechanism, located on the assembly platform, is used to send the sleeve into the positioning groove;

[0008] A sleeve pressing mechanism, located on the assembly platform, is used to press the sleeve located in the positioning groove.

[0009] The beneficial effect of the fixing device for the frame interface of the utility model lies in:

[0010] In use, first, the sleeve is fed into the positioning groove through the sleeve moving mechanism; then, the wire clamping members of the wire moving mechanism respectively clamp the two free ends of the wire, and the wire clamping members are driven by the movement of the material moving substrate to move towards the assembly platform until the wire clamped on the wire clamping members can align with the wire through hole; then, the wire clamping members move towards each other to insert the end of the wire into the sleeve through the wire through hole; finally, the sleeve is pressed by the sleeve pressing mechanism to fix the wire inserted into the sleeve within the sleeve.

[0011] By providing wire through holes for the wire to pass through on both sides of the positioning groove, the position where the wire enters the positioning groove can be guided, thereby ensuring that the wire can be accurately inserted into the sleeve within the positioning groove; and by providing two wire clamping members that move towards or away from each other, the two free ends of the wire can be driven to approach or move away from each other, so that the two free ends of the wire can enter the positioning groove from the two wire through holes respectively, ensuring that the wire can be smoothly inserted into the sleeve, which is conducive to realizing the automatic assembly of the frame.

[0012] Furthermore, the assembly platform includes a platform base and a mounting seat located on the platform base. The mounting seat is symmetrically provided with limiting insertion plates in the left-right direction. A positioning groove is defined between a pair of the limiting insertion plates, and each of the limiting insertion plates is provided with the wire through hole.

[0013] Furthermore, the inner diameter of the wire through hole gradually increases from the direction close to the positioning groove to the direction away from the positioning groove, which is conducive to the wire smoothly entering the wire through hole, and through the guidance of the wire through hole, the wire can gradually align with the sleeve within the positioning groove during the movement towards the positioning groove, so as to improve the alignment accuracy.

[0014] Furthermore, the limiting insertion plate includes a cooperating upper insertion plate and a lower insertion plate. The lower insertion plate is fixedly connected to the mounting seat. One end of the upper insertion plate is pivotally connected to the lower insertion plate, and the other end can be rotated to abut against the lower insertion plate under the action of a rotation driving member. And when the upper insertion plate abuts against the lower insertion plate, the wire through hole is jointly formed between the upper insertion plate and the lower insertion plate. Through the cooperation of the upper insertion plate and the lower insertion plate, the wire through hole presents a state that can be opened or closed. When closed, the wire can be accurately inserted into the sleeve. When opened, the completed frame after pressing can leave the wire through hole and enter the next working station through the wire moving mechanism.

[0017] Furthermore, the sleeve pressing mechanism further includes a spring. One end of the spring is connected to the mounting seat, and the other end is connected to the movable pressing die. The movable pressing die can be reset by the spring after pressing.

[0018] When the sleeve is placed into the positioning groove, the sleeve is fixed by inserting a steel wire into the sleeve. Then, the movable pressing die is driven to move by the pressing driving member, so that the sleeve can be pressed and fixed on the steel wire under the combined action of the fixed pressing die and the movable pressing die.

[0019] Furthermore, the pressing driving member includes a pressing oil cylinder and a pressing guide rod. One end of the pressing guide rod is fixedly connected to the fixed pressing die, and the other end passes through the movable pressing die.

[0037] The following elaborates on the preferred embodiments of the present utility model in conjunction with the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the protection scope of the present utility model more clearly defined.

[0038] Embodiment

[0039] Refer to the attached Figures 1-4As shown in the figure, a fixing device for a frame interface of the present utility model includes an assembly platform 1, a wire moving mechanism 2, a sleeve moving mechanism 3, and a sleeve pressing mechanism 4. Among them, a positioning groove 11 for accommodating a sleeve (not shown in the figure) is provided on the assembly platform 1, and wire through holes 12 communicating with the positioning groove 11 are symmetrically arranged at both ends of the positioning groove 11 in the left-right direction. The wire moving mechanism 2 is located on one side of the assembly platform 1, and it includes a material moving substrate 21 that moves in the direction of approaching or departing from the assembly platform 1 under the action of a driving part. Two wire clamping members 22 that can move towards or away from each other in the left-right direction are provided on the material moving substrate 21, and the wire clamping members 22 are used to clamp the ends of the wire 5. The sleeve moving mechanism 3 is located on the assembly platform 1 and is used to send the sleeve into the positioning groove 11. The sleeve pressing mechanism 4 is located on the assembly platform 1 and is used to press the sleeve located in the positioning groove 11.

[0040] During use, first, the sleeve is sent into the positioning groove 11 through the sleeve moving mechanism 3; then, the two free ends of the wire 5 are respectively clamped by the wire clamping members 22 of the wire moving mechanism 2, and the movement of the material moving substrate 21 drives the wire clamping members 22 to move towards the assembly platform 1 until the wire 5 clamped on the wire clamping members 22 can be aligned with the wire through holes 12; then, the wire clamping members 22 move towards each other to insert the end of the wire 5 into the sleeve through the wire through holes 12; finally, the sleeve is pressed by the sleeve pressing mechanism 4 so that the wire 5 inserted into the sleeve is fixed in the sleeve.

[0041] In some embodiments, refer to the attached Figure 4 As shown in the figure, the assembly platform 1 includes a platform base 13 and a mounting seat 14 located on the platform base 13. Limiting insertion plates 15 are symmetrically arranged on the mounting seat 14 in the left-right direction. A positioning groove 11 is defined between a pair of limiting insertion plates 15, and a wire through hole 12 communicating with the positioning groove 11 is provided on each limiting insertion plate 15.

[0042] Furthermore, the inner diameter of the wire through hole 12 gradually increases from the side close to the positioning groove 11 to the side far from the positioning groove 11. The flared design of the wire through hole 12 facilitates the wire moving mechanism 2 to send the wire 5 into the wire through hole 12 from the side with a larger diameter of the wire through hole 12, and to a certain extent, reduces the requirement for the moving accuracy of the wire moving mechanism 2; then, the position of the wire 5 is guided and corrected by the gradually decreasing diameter of the wire through hole 12 so that the wire 5 can be aligned with the sleeve in the positioning groove 11 and then smoothly inserted into the sleeve. Furthermore, an extension hole adapted to the outer diameter of the wire 5 is coaxially arranged on the side of the wire through hole 12 close to the positioning groove 11. The arrangement of the extension hole can stably support the wire 5 to ensure that the wire 5 always enters the positioning groove 11 along the axial direction of the wire through hole 12.

[0043] In some embodiments, the limiting insertion plate 15 may adopt a split structure. Specifically, refer to the attached Figures 4-5 As shown, the limiting insertion plate 15 includes an upper insertion plate 151 and a lower insertion plate 152 that are used in cooperation. The lower insertion plate 152 is fixedly connected to the mounting base 14. One end of the upper insertion plate 151 is pivotally connected to the lower insertion plate 152, and the other end can swing under the action of the rotation driving member 153 to abut against the lower insertion plate 152. When the upper insertion plate 151 abuts against the lower insertion plate 152, a steel wire through hole 12 is jointly formed between the upper insertion plate 151 and the lower insertion plate 152. Through the cooperation of the upper insertion plate 151 and the lower insertion plate 152, the steel wire through hole 12 can be presented in an open or closed state. When closed, the steel wire can be accurately inserted into the sleeve. When open, the completed frame can leave the steel wire through hole and enter the next working station through the steel wire moving mechanism.

[0044] In some embodiments, the rotation driving member 153 includes a driving cylinder. The cylinder barrel of the driving cylinder is fixedly connected to the platform base 13, and the piston rod of the driving cylinder is hinged to the upper insertion plate 151.

[0045] In some embodiments, refer to the attached Figure 5 As shown, the sleeve pressing mechanism 4 includes a fixed pressing die 41 and a movable pressing die 42 that are respectively located on both sides (in the front-back direction) of the positioning groove 11. The fixed pressing die 41 is fixedly connected to the mounting base 14, and a fixed pressing surface for the sleeve to abut against is provided on the side facing the positioning groove 11. The movable pressing die 42 can move in a direction approaching or away from the positioning groove 11 under the action of the pressing driving member 43, and a movable pressing surface is provided on the side of the movable pressing die 42 facing the positioning groove 11. When the sleeve is placed in the positioning groove 11, the sleeve can abut against the fixed pressing surface to enhance the positioning of the sleeve in the positioning groove 11. Then, the pressing driving member 43 is used to drive the movement of the movable pressing die 42, so that the sleeve can be pressed and fixed on the steel wire 5 under the combined action of the fixed pressing die 41 and the movable pressing die 42.

[0046] Furthermore, the sleeve pressing mechanism 4 further includes a spring. One end of the spring is connected to the mounting base 14, and the other end is connected to the movable pressing die 42. The movable pressing die 42 can be reset through the spring after pressing. When the sleeve is placed in the positioning groove 11, the sleeve is fixed by inserting the steel wire 5 into the sleeve. Then, the pressing driving member is used to drive the movement of the movable pressing die 42, so that the sleeve can be pressed and fixed on the steel wire 5 under the combined action of the fixed pressing die 41 and the movable pressing die 42.

[0047] The pressing driving member 43 includes a pressing oil cylinder and a pressing guide rod. The pressing guide rod is arranged in the front-back direction. One end of the pressing guide rod is fixedly connected to the fixed pressing die 41, and the other end passes through the movable pressing die 42. The pressing oil cylinder is fixedly connected to the mounting base 14, and its piston rod is fixedly connected to the movable pressing die 42. The pressing guide rod is provided to guide the moving direction of the movable pressing die 42.

[0048] In some embodiments, referring to the attached Figure 6 As shown, the sleeve moving mechanism 3 includes a material taking plate 32 that can move towards or away from the positioning groove 11 under the action of a sleeve driving member 31. The material taking plate 32 is inclined, and a magnetic attracting member for magnetically attracting the sleeve is provided at one end thereof facing the positioning groove 11. The setting of the magnetic attracting member can magnetically fix the sleeve to prevent the sleeve from falling during the material transfer process. The fixing of the sleeve in the positioning groove 11 is achieved by inserting a steel wire into the sleeve, and the steel wire can be kept fixed under the action of a steel wire clamping member, so that the sleeve overcomes the magnetic attraction of the magnetic attracting member and remains fixed in the positioning groove 11.

[0049] Specifically, the sleeve driving member 31 includes a gear and a rack that are meshed and driven. The gear is coaxially installed on a sleeve motor and rotates under the action of the sleeve motor. The rack is fixedly connected to the material taking plate 32 along the moving direction of the material taking plate 32. When the sleeve motor drives the gear to rotate, the rack is immediately meshed and driven, driving the material taking plate 32 to move.

[0050] In some embodiments, referring to the attached Figure 1 、 3 As shown, a sleeve feeding mechanism 6 is further provided on the assembling platform 1, and the discharge port of the sleeve feeding mechanism 6 is aligned with the material taking plate 32 to facilitate the material taking operation of the material taking plate 32.

[0051] In some embodiments, the driving part of the steel wire moving mechanism 2 is a cross slide table structure, which can drive the material moving substrate 21 to move in the front-rear direction and the up-down direction, so that the steel wire clamping member 22 can drive the steel wire 5 to move in the front-rear and up-down directions. Further, the steel wire clamping member 22 is a pneumatic gripper.

[0052] It should be noted that the forward or backward movement of the steel wire clamping members 22 on the material moving substrate 21 is to cooperate with the action of inserting the steel wire 5 into the sleeve. In order to center the two steel wire clamping members 22 relative to the positioning groove 11, the left-right position of the material moving substrate 21 relative to the assembling platform 1 or the position of the assembling platform 1 relative to the material moving substrate 21 can be adjusted. Exemplarily, referring to the attached Figure 3 As shown, a platform moving mechanism 7 is provided below the assembling platform 1. The platform moving mechanism 7 includes a linear lead screw arranged in the left-right direction. One end of the linear lead screw is connected to a driving handle, and a nut seat connected to the assembling platform 1 is threadedly sleeved thereon. The setting of the platform moving mechanism 7 can drive the assembling platform 1 to move in the left-right direction.
