Problems solved by technology

[0002] The central shaft hole of the channel steel of the main frame of the pay-off block is ∮55, and the hole diameter is relatively large. During the production process, the vise is generally used for drilling, because the hole drilled on the vise can only clamp one slot For steel, the vise needs to be opened every time to carry out loading, clamping, drilling, loosening, and unloading in sequence. Not only is the production efficiency low, but also, due to the small contact surface of the vise, it is easy to cause arching when multiple workpieces are clamped. , the drilled holes are easy to deviate, resulting in low drilling accuracy and low scrap rate, which is not conducive to machining and affects the assembly of the pay-off block

Embodiment 1

[0020] Such as figure 1 and figure 2 As shown, a channel steel drilling and fixing platform for the main frame of a pay-off block includes two bases 1 arranged in parallel, and a stopper vertically located between the two bases 1 for horizontally accommodating workpieces 6 made of five channel steels. ㄧ2 and head Ⅱ3, the base 1, the head ㄧ2 and the head Ⅱ3 are all made of angle steel, the base 1 can be fixed on a higher position by fastening bolts, such as on the metal platform 8; the outer side of the head ㄧ2 A fixed bracket 5 for placing the jack 4 to clamp the workpiece 6 is provided. The fixed bracket 5 is provided with reinforcing ribs 51 for increasing the bearing pressure. The stopper 2 is provided with a round hole for the top of the jack 4 to pass through 7.

[0021] On the two bases 1, there are symmetrically spaced pressing devices to prevent the movement of the workpiece. The ring 92 and the compression strip 93 passing through all the compression rings 92 on t...

Embodiment 2

[0025] The difference between this embodiment and embodiment 1 is: see image 3 , the support rod 91 includes a first support rod 101 fixedly connected to the base 1 and a second support rod 102 threaded with the first support rod 101, the second support rod 102 is provided with a rectangular compression ring 92, and the compression bar The section of 93 is also rectangular. The threaded connection can adjust the total length of the first support rod 101 and the second support rod 102, which is convenient to be applied to workpieces 6 of different thicknesses, and has stronger practicability.

Abstract

The invention discloses a drilling and fixing platform for a steel channel of a paying-off tackle main frame and belongs to the technical field of special tools for electric equipment. The drilling and fixing platform comprises two bases arranged in parallel, a stop head I and a stop head II, wherein the stop head I and the stop head II are perpendicularly located between the two bases and used for containing workpieces. A fixing support used for installing a jack to clamp the workpieces is arranged on the outer side of the stop head I. A round hole allowing a jack head of the jack to penetrate is formed in the stop head I. The bases are provided with a pressing device for preventing the workpieces from moving. The pressing device comprises multiple supporting rods, pressing rings arranged on the supporting rods and pressing strips, wherein each pressing strip penetrates the pressing rings on the same base. By the adoption of the drilling and fixing platform, the drilling efficiency is improved by over three times compared with that of a vice, time is saved, and production efficiency is improved; due to the fact that the pressing device is arranged, the phenomenon that multiple workpieces are arched upwards when flatly placed in drilling operation can be effectively prevented, and the contact area of the platform is large; and in the drilling process, the safety coefficient is high, drilling deviation is not likely to happen, and the product quality of a paying-off tackle is guaranteed.
