[0002] Dovetail pads are usually used as insulating components in electrical equipment such as transformers. They are generally made of insulating material stays punched through a stamping machine. During the stamping process of the dovetail pads, the stays usually need to be transferred to the stamping end for stamping in sequence. The inventor previously disclosed a fully automatic stamping machine with a patent number of CN117531928. The material is transported to the stamping device 2 for stamping through a feeding device 3. The whole process can be fully automatic. However, two sets of driving rollers are usually set before the stamping end to smoothly transport the lifted material to the stamping end, and before the two sets of driving rollers, a A support platform is provided so that the material can remain in a horizontal state and the stamping quality is improved. A channel is provided on the support platform for the material to pass through. In order to facilitate the punching of stays of different widths by the punching machine, the size of the channel needs to be adjustable. In the above patent, the distance is adjusted by fixing multiple bolts with multiple different channels. However, in actual use, on the one hand, the tightening and loosening of multiple bolts wastes a lot of time, and due to the limited width of the support platform, the number of channels should not be too many and the spacing should not be too small, so that the range of channel adjustment is small, the applicable stay size range is relatively limited, and the practicality is low.

DETAILED DESCRIPTION

[0028] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0029] Example

[0030] As mentioned in the background technology, during the processing of the dovetail pad, the struts need to be transported to the stamping end of the stamping bed 1 for stamping processing. The transmission of the struts needs to pass through the adsorption loading device and the conveying roller group 2. In order to keep the struts horizontal and support them before stamping, a channel needs to be set between the two groups of conveying roller groups 2, and the channel can be adjusted to adapt to struts of different widths. The stamping bed 1 previously designed by the inventor has certain defects when adjusting the channel spacing, and the adjustment efficiency and range can only meet basic production needs. Therefore, the inventor has made improvements based on the previous technology and designed a new spacing adjustment component, which is explained in detail below with reference to the drawings.

[0031] This embodiment provides a feed port spacing adjustment assembly for a punching machine, see Figure 1 and Figure 2 , installed between the two groups of conveying roller groups 2 of the punching bed 1, including a support platform 3 installed with the roller frames 21 of the two groups of conveying roller groups 2, the support platform 3 is fixed between the two groups of roller frames, and can be fixedly installed with the two groups of roller frames 21 by bolts and other components, and the width of the support platform 3 is not less than the length of the roller 22 of the conveying roller group 2, and is at least consistent with the length of the roller 22, to ensure that when conveying a larger width of the stay, the support platform 3 can support all the stays, thereby improving the stability of the stays during transmission.

[0032] On the basis of the above structure, the support platform 3 is provided to support the bottom of the strut, and in order to prevent the strut from deflecting during transmission, two limit plates 4 are provided on the support platform 3, the length direction of the limit plates 4 is consistent with the length direction of the support platform 3, and the two limit plates 4 can move toward or away from each other along the support platform 3, and can be fixed at any position in the moving direction, so that the distance between the two limit plates 4 can be adjusted, and then the struts of different widths can be limited. Since the maximum width of the struts that can be transmitted by the conveying roller group 2 does not exceed the length of the roller 22, the maximum spacing that the two limit plates 4 can reach is not greater than the length of the roller 22.

[0033] In this example, one of the biggest contributions to the prior art is that Figure 3-Figure 5 The distance adjustment of the two limit plates 4 is achieved through a driving component 6, wherein a mounting frame 5 is arranged on the side of the support platform 3, and a driving component 6 is arranged through the mounting frame 5, and the output end of the driving component 6 is connected with the two limit plates 4, which can drive the two limit plates 4 to move along the transmission direction of the vertical conveying roller group 2, and when the driving component 6 stops adjusting, the two limit plates 4 can be fixed, and the position of the limit plates 4 can be adjusted relative to the replacement fixing holes of the transmission, and the limit plates 4 are fixed by multiple bolts. The driving component 6 greatly facilitates the adjustment and fixation of the limit plates 4 and improves the adjustment efficiency.

[0034] Specifically, in order to facilitate the installation of the drive assembly 6, Figure 5The mounting frame 5 is a U-shaped structure with the opening facing downward, and spans the support platform 3, and is fixed to the support platform 3 on both sides. Specifically, the vertical end of the mounting frame 5 with the U-shaped structure can be fixed to the side of the support platform 3 by bolts and other components. The driving assembly 6 includes a lead screw 61 rotatably installed in the mounting frame 5, and the lead screw 61 is provided with two sections of reverse threads, and two driving blocks 62 are connected by the two sections of threads. The bottom ends of the two driving blocks 62 are respectively fixed to the two limit plates 4, and one end of the lead screw 61 passes through the mounting frame 5 and is installed with a rotating handle 63. The lead screw 61 is driven to rotate by rotating the handle 63, and then under the action of the thread, the two driving blocks 62 move toward or away from each other along the lead screw 61, and then drive the two limit plates 4 to move to the required spacing.

[0035] Moreover, sliders 7 are provided at the bottom of the two limit plates 4, and slide grooves 8 for the sliders 7 to slide are provided on the support platform 3. When the limit plates 4 move, the sliders 7 slide along with them in the slide grooves 8, thereby improving the stability of the limit plates 4 when sliding.

[0036] It should be noted that the above-mentioned drive component 6 adopts manual control, and the rotating handle 63 can also be replaced with a motor for electronic control, and the entire drive component 6 can be set in the form of an electric cylinder, specifically two of which are connected to the two limit plates 4 through the mounting frame 5, and the two limit plates 4 are driven to move along the support platform 3 through telescoping.

[0037] Based on the above structure, combined with Figure 3 In this solution, when adjusting the spacing of the limit plate 4, the moving distance can also be observed. A rectangular hole 64 is provided along the length direction of the upper end of the mounting frame 5, which is in the shape of a long strip, and a scale line 65 is provided on the edge of the rectangular hole 64. The value of the scale line 65 gradually increases from the middle position of the upper end surface of the mounting frame 5 to both sides. An indicator block 66 is installed on the upper end of the driving block 62, and the indicator block 66 extends to the upper edge of the rectangular hole 64 and is slidably arranged with the rectangular hole 64, and can be aligned with the scale line 65 for easy observation. The driving block 62 and the indicator block 66 are close to the lead screw 61. One side of the center is flush with the edge of the limit plate 4 below, so that the side of the indicator block 66 close to the center of the screw 61 represents the horizontal position of the limit plate 4, and the middle position of the scale line 65 is the zero line. Therefore, when adjusting the spacing, according to the width of the strut, rotate the screw 61 to drive the side of the indicator block 66 to move to the position of the scale line 65 which is half the width of the strut. The distance between the two indicator blocks 66 is the width of the strut, and in order to facilitate the movement of the strut, the distance between the indicator blocks 66 should be adjusted to be slightly larger than the width of the strut, specifically kept between 2mm-6mm.

[0038] When carrying out the support conveying, Figure 4-Figure 6The spring 94 and the support rod are pressed together to prevent the stretching of the support rod 5 and the stretching of the roller 93.
