Description

[0002] When processing the heat dissipation plate of the distribution cabinet, steps such as opening heat dissipation openings for the heat dissipation plate material need to be carried out through a forming machine. However, in the prior art, the fixing effect during the forming of the heat dissipation plate is not good, which is not convenient for the forming of the heat dissipation plate, resulting in the deviation of the positions of the heat dissipation holes on the heat dissipation plate and reducing the processing quality of the heat dissipation plate. At the same time, in the prior art, when transporting the heat dissipation plate material, it is often through an intelligent automation device, and each time the heat dissipation plate material is controlled to advance a distance of one heat dissipation plate, so as to control the cutting knife to cut off the processed heat dissipation plate. However, this kind of intelligent device is expensive, has high maintenance costs, requires a large cost investment, and has a high economic investment, and does not save costs.

[0003] To solve such problems, relevant technical personnel have designed a positioning and fastening device as shown in CN114683047A. The material is fixed on the conveyor belt by the elastic force of the circumferentially arranged elastic telescopic tubes, and the material is driven to move by the rotation of the elastic telescopic tubes.

[0023] The embodiments of the present invention aim to introduce and explain the structural composition of the positioning and fastening device of a high and low voltage power distribution cabinet heat dissipation plate processing and forming machine and the cooperation relationship between the various component structures. Unless otherwise specified, the dimensions, materials, manufacturing processes, etc. of the various components in the positioning and fastening device suitable for the high and low voltage power distribution cabinet heat dissipation plate processing and forming machine in the embodiments of the present invention can be selected according to specific circumstances, and no special limitations and explanations are made here.

[0024] Furthermore, in order to enable the public to have a better understanding of the present invention, in the following detailed description of the present invention, some specific detailed parts are described in detail. Those skilled in the art can fully understand the present invention without the description of these detailed parts.

[0025] Please refer to Figures 1-4 , this embodiment provides a positioning and fastening device for a high and low voltage power distribution cabinet heat dissipation plate processing and forming machine, including a frame 1, a receiving roller 11, a conveyor belt 12, a connecting plate 13, a rotating assembly 2, a first transmission belt 3, an elastic fixing assembly 4, an adjusting assembly 5, a cutting mechanism 6, a transmission assembly 7, a second transmission belt 8 and a driven assembly 9; A number of driving rollers are rotatably provided on both sides of the frame 1, and the conveyor belt 12 tightly surrounds the receiving rollers 11 on the same side; specifically, the receiving rollers 11 on both sides are symmetrically arranged, and the rotation of one receiving roller 11 drives the rotation of other receiving rollers 11 through the conveyor belt 12. At the same time, it should be understood that the material is placed on the conveyor belt 12.

[0026] A connecting plate 13 is provided on the frame 1, and a number of rotating assemblies 2 are rotatably provided on the connecting plate 13, and the first transmission belt 3 tightly surrounds the rotating assemblies 2 on the same side; specifically, connecting plates 13 are provided on both sides of the frame 1, and a number of rotating assemblies 2 are symmetrically provided on the two connecting plates 13, and the rotation of any rotating assembly 2 can drive the rotation of other rotating assemblies 2 on the same side through the first transmission belt 3.

[0027] A number of elastic fixing assemblies 4 are circumferentially and liftably provided on the same rotating assembly 2, and the adjusting assembly 5 is rotatably provided on the rotating assembly 2 and can adjust the elastic force of the elastic fixing assembly 4; It should be understood that the elastic fixing assembly 4 fixes both sides of the material on the conveyor belt 12. When the rotating assembly 2 is stationary, the material is fixed on the conveyor belt 12 by the elastic force of the elastic fixing assembly 4. When the rotating assembly 2 rotates, the rotating elastic fixing assembly 4 drives the material to move forward, and makes the latter elastic fixing assembly 4 contact and press on the material, that is, the material moves with the rotation of the elastic fixing assembly 4 and stops with the stationary of the elastic fixing assembly 4.

[0028] The rack 1 is also provided with a cutting mechanism 6. A transmission assembly 7 is rotatably arranged on the cutting mechanism 6. The operation of the cutting mechanism 6 can drive the transmission assembly 7 to rotate. A driven assembly 9 is also arranged on the rotating assembly 2 close to the cutting mechanism 6. The driven assembly 9 is in an annular shape. The second transmission belt 8 tightly surrounds the driven assembly 9 and the transmission assembly 7. That is, the rotation of the transmission assembly 7 drives the driven assembly 9 to rotate through the second transmission belt 8, and the rotation of the driven assembly 9 drives the rotating assembly 2 to rotate. Thus, the cutting action of the cutting mechanism 6 can make the material advance. Specifically, since the operation of the cutting mechanism 6 unidirectionally rotates the transmission assembly 7 and each cutting stroke is fixed, it can be set that the transmission assembly 7 rotates when the cutting mechanism 6 lifts after cutting, so that the material advances a fixed distance after each cutting is completed. Preferably, the second transmission belt 8 is an elastic belt with good elasticity.

[0029] In addition to the above structures, the rack 1 is also provided with a forming device, a lower template, conveyor rollers connecting the rack 1 and the cutting device, etc. structures that enable the device to work properly. For details, reference can be made to CN114683047A, which will not be elaborated herein.

[0030] In this application, the elastic force of the elastic fixing component 4 is adjusted by the adjusting component 5, so that when dealing with plates of different thicknesses, it can be in an appropriate elastic force, avoiding damage to the surface of the plate caused by too strong elastic force of the elastic fixing component 4, or it is difficult to make the elastic fixing component 4 contract to place the plate under it when the plate thickness is too large during feeding.

[0031] In other solutions, the rotating assembly 2 includes a first runner 21 and a connecting cylinder 22. The first runner 21 is rotatably connected to the connecting plate 13, and the first transmission belt 3 tightly surrounds the first runner 21 on the same side. The connecting cylinder 22 is coaxially fixed on the first runner 21, and the elastic fixing component 4 is circumferentially arranged on the connecting cylinder 22. Preferably, the first runner 21 is a pulley.

[0032] In other solutions, the elastic fixing component 4 includes a fixed tube 41, a sliding tube 42, a support spring 43, a pressing plate 44 and a connecting rope 45. The fixed tube 41 is fixed on the rotating assembly 2, specifically fixed on the connecting cylinder 22 along the circumferential direction. The sliding tube 42 is slidably connected to the fixed tube 41 in a liftable manner. The sliding tube 42 is connected to the fixed tube 41 through the support spring 43, and the pressing plate 44 is fixed on the top of the sliding tube 42. One end of the connecting rope 45 is connected to the sliding tube 42, and the other end is wound and fixed on the adjusting component 5. The rotation of the adjusting component 5 can adjust the winding degree of the connecting rope 45. It should be understood that the pressing plate 44 is used to press on the plate to fix and move the plate. It should also be understood that the elastic force of the support spring 43 will not drive the connecting rope 45 to disengage from the adjusting component 5.

[0033] In other solutions, the adjusting assembly 5 includes a threaded rod 51 and a winding rod 52; the threaded rod 51 is screwed onto the rotating assembly 2, the winding rod 52 is coaxially fixed on the threaded rod 51, and the connecting rope 45 is wound and fixed on the winding rod 52. The rotation of the threaded rod 51 can limit the angle of the winding rod 52 to prevent it from rotating driven by the support spring 43. By rotating the threaded rod 51 forward or backward, the connecting rope 45 can be tightened or released, thereby changing the winding condition of the connecting rope 45 and changing the magnitude of the elastic force.

[0034] In other solutions, the driven assembly 9 includes a driven drum 91, a driven rod 92, and an arc-shaped plate 93; the driven drum 91 is coaxially fixed on the rotating assembly 2, specifically, the driven drum 91 is coaxially fixed on the connecting cylinder 22. A plurality of driven rods 92 are circumferentially arranged on the driven drum 91, and arc-shaped plates 93 are fixed on the driven rods 92. Specifically, the second transmission belt 8 surrounds the ring-shaped or quasi-ring-shaped structure composed of the transmission assembly 7 and a plurality of arc-shaped plates 93. It should also be understood that on the rotating assembly 2 provided with a driven cylinder, the threaded rod 51 is screwed onto the driven cylinder.

[0035] In other solutions, the rotation of the adjusting assembly 5 can also change the outer diameter of the driven assembly 9. That is, the outer diameter of the ring in contact with the second transmission belt 8 and the driven assembly 9 is changed. Since the angle of each rotation of the transmission assembly 7 remains unchanged, by changing its outer diameter, the angle of the driven assembly 9 driven by the second transmission belt 8 can be made different, thereby adjusting the forward distance of the plate. In addition to relying on the elasticity of the second transmission belt 8 itself, it is also preferable to replace the second transmission belt 8 with different lengths to adapt to the driven assembly 9 after the change in the outer diameter. Since heat dissipation plates with different thicknesses usually also have different dimensional requirements, the forward distance of the plate each time in the original device changes. Through this structure, the forward distance of the plate each time can be adjusted while adjusting the thickness, adapting to products of different sizes, making the application more extensive. Specifically, since the radius of the second runner 72 driving the second transmission belt to rotate is unchanged and the height of the rack's descent is unchanged, that is, the contact length of the second transmission belt with the ring formed by the arc-shaped plates 93 each time is fixed. By changing the diameter of the ring formed by each arc-shaped plate 93, the angle by which the second transmission belt can drive the arc-shaped plate 93 to rotate each time can be changed, thereby cutting off plates of different lengths.

[0036] In other solutions, a wedge block 53 is fixed on the threaded rod 51, the driven rod 92 is slidably passed through the driven drum 91, and the movement of the wedge block 53 can squeeze the sliding rod to make it lift or lower. Specifically, pushing the driven rod 92 inward can lift it, and moving outward will cause it to fall along the inclined surface of the wedge block 53. It should be understood that in this structure, there are gaps between the arc-shaped plates 93, and the gap size can be adjusted by the lifting and lowering of the driven rod 92. The wedge block 53 is preferably a conical wedge block 53.

[0037] In other solutions, the cutting mechanism 6 includes a mounting frame 61, a hydraulic cylinder 62, a cutting tool 63, a cutting connecting rod 64, and a rack 65; the mounting frame 61 is fixedly arranged on the machine frame 1, the hydraulic cylinder 62 is fixedly arranged on the mounting frame 61 and is connected to the cutting tool 63; a long slot is provided on the mounting frame 61, one end of the cutting connecting rod 64 is connected to the cutting tool 63, and the other end is connected to the rack 65. The sliding of the rack 65 can drive the driven assembly 9 to rotate unidirectionally.

[0038] In other solutions, the transmission assembly 7 includes a flywheel 71 and a second runner 72; the flywheel 71 is rotatably connected to the mounting frame 61, the rack 65 can drive the flywheel 71 to rotate unidirectionally, and the second runner 72 is coaxially fixedly arranged on the flywheel 71. The flywheel 71 is common in the rear wheel of a bicycle. When the flywheel 71 rotates forward, the outer wall can drive the inner wall to rotate synchronously, but when the flywheel 71 rotates reversely, the outer wall will rotate relative to the inner wall. The second runner 72 is preferably a pulley and is arranged on the side wall of the flywheel 71. The second transmission belt 8 tightly surrounds the second runner 72 and several arc-shaped plates 93.

[0039] In other solutions, a lower baffle 94 is further provided on the driven rod 92. By providing the lower baffle 94, the downward bottom position of the driven rod 92 can be restricted.

[0040] The positioning and fastening device of the above-mentioned high and low voltage power distribution cabinet heat dissipation plate processing and forming machine can change the elastic force of the elastic fixing component, so as to adapt to more heat dissipation plate sheets of different sizes.

[0041] It should be understood that the above embodiments are only used to illustrate the technical concept and features of the present invention, and the purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several simple deductions or substitutions can also be made. Any equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
