Description

Technical Field

[0001] This utility model relates to the field of refrigerator back panel processing technology, specifically to a middle clamping device for refrigerator back panel processing. Background Technology

[0002] The processing of refrigerator back panels typically involves the following main steps: First, select suitable sheet materials, such as galvanized steel sheets or aluminum sheets, to ensure that the materials meet the quality and performance requirements. Then, use cutting equipment to precisely cut out the required back panel shape and size according to the design dimensions. Finally, use stamping processes to create specific concave and convex shapes, mounting holes, and other structures.

[0003] However, during the processing, the middle of the workpiece needs to be tightened to prevent the workpiece from shifting position during processing. However, the current tightening device is fixed to the top of the device, so the tightening position cannot be adjusted according to the size of the workpiece. At the same time, the two sides of the workpiece do not have positioning devices, which can easily cause them to shake during processing.

[0004] Therefore, this utility model provides a clamping device for the middle part of the refrigerator back panel processing. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a clamping device for the middle part of the refrigerator back panel processing to solve the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a clamping device for the middle part of a refrigerator back panel, comprising a base, a controller fixedly connected to the outer side of the base, a workpiece placed on the base, a gantry fixedly connected to the top of the base, a hydraulic cylinder fixedly connected to the top of the gantry, a clamping plate fixedly connected to the bottom of the hydraulic cylinder, a sliding groove provided inside the gantry, an L-shaped plate fixedly connected to the outer side of the hydraulic cylinder, a threaded tube fixedly connected to the outer side of the L-shaped plate, a screw threadedly connected inside the threaded tube, and a positioning cover fixedly connected to the outer side of the screw.

[0007] Preferably, a pressing rod is fixedly connected to the outer side of the output end of the hydraulic cylinder, a power supply box is fixedly connected to the inner side of the gantry, an elastic switch is fixedly connected to the top of the power supply box, a wire is fixedly connected to the outer side of the power supply box, an electric telescopic rod is fixedly connected to the outer side of the gantry, a push rod is fixedly connected to the outer side of the electric telescopic rod, a moving plate is fixedly connected to the outer side of the push rod, a buffer spring is fixedly connected to the outer side of the moving plate, and a positioning plate is fixedly connected to the outer side of the buffer spring.

[0008] Preferably, the output end of the hydraulic cylinder is slidably connected in a groove inside the gantry frame, and the top clamping plate is movably connected above the workpiece. The hydraulic cylinder is activated by the controller, thereby causing the top clamping plate to move downward to clamp the workpiece on the top of the base.

[0009] Preferably, the L-shaped plates are symmetrically distributed on the outside of the hydraulic cylinder, and the positioning cover is movably connected to the outside of the gantry frame by a screw. The screw rotates inside the threaded tube, thereby causing the screw to move the positioning cover.

[0010] Preferably, the extrusion rods are symmetrically distributed on the outer side of the output end of the hydraulic cylinder, and the elastic switch is located directly below the extrusion rods. When the hydraulic cylinder is started, it will drive the extrusion rods to move downward, thereby causing the extrusion rods to push the elastic switch.

[0011] Preferably, the electric telescopic rod is electrically connected to the power supply box via a wire, and the push rod passes through the interior of the gantry frame. The electric telescopic rod is activated through the power supply box, thereby causing the electric telescopic rod to drive the push rod to move.

[0012] Preferably, the movable plate is slidably connected to the top of the base, and the positioning plate is movably connected to the outside of the workpiece via a buffer spring. By fixing the buffer spring between the positioning plate and the movable plate, it is possible to prevent the workpiece from being damaged due to excessive clamping force of the positioning plate.

[0013] Beneficial effects

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] (1) The back panel processing center clamping device of the refrigerator is equipped with a base. First, a workpiece is placed on the top of the base. The hydraulic cylinder at the top of the gantry is started by the controller. At this time, the hydraulic cylinder will drive the clamping plate to move downward, so that the clamping plate clamps the workpiece at the top of the base. When it is necessary to adjust the clamping position, the screw is first rotated inside the threaded tube, so that the screw drives the positioning cover away from the gantry. At this time, the hydraulic cylinder moves at the top of the gantry, so that the position of the clamping plate is adjusted. When the position is adjusted to a suitable position, the screw is reversed, so that the screw drives the positioning cover to move to the outside of the gantry again, which can position the hydraulic cylinder at the top of the gantry, thus achieving the effect of adjusting the clamping position.

[0016] (2) The back panel of the refrigerator is processed with a clamping device in the middle. By setting a base, when the hydraulic cylinder is started, its output end drives the clamping plate to move downward. At this time, the extrusion rod also moves downward. The movement of the extrusion rod can squeeze the elastic switch on the top of the power box, thereby energizing the power box. At this time, the power box will start the electric telescopic rod, thereby driving the push rod to move. Through the cooperation of the outer moving plate of the push rod and the buffer spring, the positioning plate can position the two sides of the workpiece, thereby preventing the two sides of the workpiece from shaking.

[0024] Furthermore: the output end of the hydraulic cylinder 5 is slidably connected in the slide groove 7 inside the gantry 4, the top clamping plate 6 is movably connected above the workpiece 3, the L-shaped plates 8 are symmetrically distributed on the outside of the hydraulic cylinder 5, and the positioning cover 11 is movably connected to the outside of the gantry 4 through the screw 10.

[0025] It should be noted that: the controller 2 starts the hydraulic cylinder 5, thereby moving the top plate 6 downward to tighten the workpiece 3 on the top of the base 1. The screw 10 rotates inside the threaded tube 9, thereby moving the positioning cover 11.

[0026] As a further improvement of this utility model, a pressing rod 12 is fixedly connected to the outer side of the output end of the hydraulic cylinder 5, a power supply box 13 is fixedly connected to the inner side of the gantry frame 4, an elastic switch 14 is fixedly connected to the top of the power supply box 13, a wire 15 is fixedly connected to the outer side of the power supply box 13, an electric telescopic rod 16 is fixedly connected to the outer side of the gantry frame 4, a push rod 17 is fixedly connected to the outer side of the electric telescopic rod 16, a moving plate 18 is fixedly connected to the outer side of the push rod 17, a buffer spring 19 is fixedly connected to the outer side of the moving plate 18, and a positioning plate 20 is fixedly connected to the outer side of the buffer spring 19.

[0027] Furthermore: the extrusion rods 12 are symmetrically distributed on the outside of the output end of the hydraulic cylinder 5, the elastic switch 14 is located directly below the extrusion rods 12, the electric telescopic rod 16 is electrically connected to the power supply box 13 through the wire 15, the push rod 17 passes through the inside of the gantry frame 4, the moving plate 18 is slidably connected to the top of the base 1, and the positioning plate 20 is movably connected to the outside of the workpiece 3 through the buffer spring 19.

[0028] It should be noted that when the hydraulic cylinder 5 is started, it will drive the extrusion rod 12 to move downward, thereby pushing the elastic switch 14. The power supply box 13 will start the electric telescopic rod 16, thereby driving the push rod 17 to move. Because a buffer spring 19 is fixedly connected between the positioning plate 20 and the moving plate 18, it can prevent the workpiece 3 from being damaged due to excessive clamping force of the positioning plate 20.

[0029] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0030] Working Principle: A base 1 is installed, and a workpiece 3 is placed on top of it. The controller 2 activates the hydraulic cylinder 5 on top of the gantry frame 4. This hydraulic cylinder 5 moves the clamping plate 6 downwards, clamping the workpiece 3 on top of the base 1. When the clamping position needs adjustment, the screw 10 rotates inside the threaded tube 9, moving the positioning cover 11 away from the gantry frame 4. The hydraulic cylinder 5 then moves on top of the gantry frame 4, adjusting the position of the clamping plate 6. Once the desired position is reached, the screw 10 is reversed, moving the positioning cover 11 back to the outside of the gantry frame 4. The hydraulic cylinder 5 at the top of the gantry 4 can be positioned to achieve the effect of adjusting the clamping position. By setting the base 1, when the hydraulic cylinder 5 is started, its output end drives the clamping plate 6 to move downward. At this time, the pressing rod 12 also moves downward. The movement of the pressing rod 12 can squeeze the elastic switch 14 at the top of the power box 13, thereby energizing the power box 13. At this time, the power box 13 will start the electric telescopic rod 16, which will drive the push rod 17 to move. Through the cooperation of the outer moving plate 18 of the push rod 17 and the buffer spring 19, the positioning plate 20 can position the two sides of the workpiece 3, thereby preventing the two sides of the workpiece 3 from shaking.
