Description

Technical Field

[0001] This utility model relates to the field of sofa processing technology, specifically a positioning and drilling device for sofa processing. Background Technology

[0002] Sofas can be classified by function into functional sofas, fixed-back sofas, infinitely adjustable sofas, pneumatic sofas, electric sofas, and sofas with TVs, etc. Sofas have become an essential piece of furniture for many families. In the manufacturing process of sofas, people will punch several pairs of holes in the sponge cushions of the sofa before putting on the sofa leather to increase the breathability of the sofa.

[0003] In existing drilling devices, the softness of the sponge can cause deformation during the drilling process, leading to drilling failure or misalignment. Existing technologies can only accommodate sofas of fixed sizes, making it unsuitable for smaller sofas and limiting the widespread application of the device. Therefore, we propose a positioning drilling device for sofa processing. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a positioning and drilling device for sofa processing. When drilling holes in soft materials such as sponge, the position and shape of the holes will not change due to the softness of the sponge. It can be used for sofas of different sizes and smaller sizes, and can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning and drilling device for sofa processing, comprising a base plate, a moving unit, a placing unit, and a drilling unit;

[0006] Base plate: A moving unit is installed at the top;

[0007] The moving unit includes a sliding groove, a threaded rod, a motor, and a mounting bracket. The upper left and right ends of the base plate have two sliding grooves. The threaded rod is rotatably connected in the left sliding groove. The upper rear side of the base plate is fixedly connected to the motor. The input shaft of the motor is fixedly connected to the threaded rod. The lower left and right sides of the mounting bracket are slidably connected to the sliding grooves. The lower end of the mounting bracket is threadedly connected to the threaded rod.

[0008] Placement unit: mounted on the base plate;

[0009] Drilling unit: Installed on the moving unit.

[0010] The motor drives the threaded rod to rotate, causing the mounting bracket to slide along the inside of the sliding groove, thereby driving the drilling device to move in a position.

[0011] Furthermore, the placement unit includes a second sliding groove, limiting posts, a bidirectional threaded rod, a second motor, and a sliding seat. The second sliding groove is located at the center of the upper end of the base plate. A bidirectional threaded rod is rotatably connected to the center of the inner side of the second sliding groove. Two limiting posts are fixedly connected to the left and right sides of the inner side of the second sliding groove. Two sliding seats are slidably connected to the front and rear sides of the inner side of the second sliding groove. The sliding seats are slidably connected to the limiting posts and threadedly connected to the bidirectional threaded rod. A second motor is fixedly connected to the center of the rear end of the base plate, and the output shaft of the second motor is fixedly connected to the bidirectional threaded rod. The second motor drives the bidirectional threaded rod to rotate, and the limiting posts and the second sliding groove limit the movement of the sliding seats. The movement of the sliding seats allows for the placement of sofas of different sizes, facilitating the drilling of holes in sofas of different sizes.

[0012] Furthermore, the placement unit also includes a hydraulic press and a placement plate. Two hydraulic presses are fixedly connected to the upper left and right sides of the sliding seat, and the placement plate is fixedly connected to the upper end of the hydraulic press. The hydraulic press drives the placement plate to rise and fall, and the sofa is placed on the placement plate. The rising and falling of the placement plate brings the sofa closer to the drilling device, thus facilitating the positioning and drilling of the sofa.

[0013] Furthermore, the drilling unit includes a sliding plate, a second hydraulic press, an electric telescopic rod, a pusher, a third motor, and a second threaded rod. The upper end of the mounting frame is slidably connected to the sliding plate, and the middle of the upper end of the mounting frame is rotatably connected to the second threaded rod. The right side of the upper end of the mounting frame is fixedly connected to the third motor, and the output shaft of the third motor is fixedly connected to the second threaded rod. The second threaded rod is threadedly connected to the sliding plate. The lower end of the sliding plate is fixedly connected to the second hydraulic press, and the lower end of the second hydraulic press is fixedly connected to the drilling cutter. The inner side of the upper end of the drilling cutter is fixedly connected to the electric telescopic rod, and the lower end of the electric telescopic rod passes through the inner side of the drilling cutter and is fixedly connected to the pusher. The pusher is slidably connected to the drilling cutter. Motor 3 drives threaded rod 2 to rotate, and the rotation of threaded rod 2 causes the sliding plate to slide on the upper end of the mounting frame, thereby achieving the positioning of the horizontal drilling position. The hydraulic press 2 lifts and lowers to drill holes at the required positions. The drilling knife drills holes in the sofa's sponge and wood panels. The electric telescopic rod and pusher inside the drilling knife push out the excess material generated by drilling, thus facilitating faster and easier drilling of the sofa.

[0014] Furthermore, the punching unit also includes a hydraulic press and a pressure plate. Two hydraulic presses are fixedly connected to the lower left and right sides of the inner side of the mounting frame, and a pressure plate is fixedly connected to the upper end of each hydraulic press. The hydraulic press drives the pressure plate to rise and fall, thus providing a larger contact area for the sponge when punching softer materials. This facilitates the punching device in punching sponges and soft materials, ensuring that the position and shape of the punches are not altered due to the softness of the sponge.

[0015] Furthermore, it also includes a collection tray, which is snapped into the lower center of the inner side of the mounting bracket. The collection tray is used to collect and process excess material from drilling.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: The positioning and drilling device for sofa processing has the following advantages:

[0017] 1. The positioning and drilling device used in the processing of this sofa uses a hydraulic press to drive the pressure plate to rise and fall, so that when drilling softer sponges, the sponge has a larger contact area. This makes it easier for the drilling device to drill holes in sponges and soft materials, so that the position and shape of the holes will not change due to the softness of the sponge.

[0018] 2. The positioning and drilling device used for processing this sofa can place sofas of different sizes by moving the sliding seat, which makes it easier to drill holes in sofas of different sizes. At the same time, by raising and lowering the placement plate, the sofa can be brought closer to the drilling device, which facilitates the positioning and drilling of the sofa.
