Description

Channel steel drilling and fixing platform for the main frame of the pay-off block

technical field

The invention relates to a channel steel drilling and fixing platform for a main frame of a pay-off tackle, and belongs to the technical field of special tools for electric equipment.

Background technique

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 high scrap rate, which is not conducive to machining and affects the assembly of the pay-off block.

Contents of the invention

The technical problem to be solved by the present invention is to provide a channel steel drilling and fixing platform for the main frame of the pay-off block with high production efficiency and high yield.

In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:

A channel steel drilling fixed platform for the main frame of a pay-off block, including two bases arranged in parallel, a stopper Ⅰ and a stopper Ⅱ vertically located between the two bases for accommodating workpieces, and the outer side of the stopper Ⅱ is provided with a The jack is placed to clamp the fixed bracket of the workpiece. The stopper is provided with a round hole for the top of the jack to pass through. The base is provided with a pressing device to prevent the workpiece from moving. The pressing device includes several fixed connections on the base. The support rods on the upper part, the compression rings arranged on the upper part of each support rod and the compression strips passing through the compression rings on the same base.

The further improvement of the technical solution of the present invention lies in that the support rod includes a first support rod fixedly connected to the base and a second support rod screwed to the first support rod, and a compression ring is provided on the second support rod.

A further improvement of the technical solution of the present invention lies in that the pressing ring is circular or rectangular.

The further improvement of the technical solution of the present invention lies in that: the base, the stopper I and the stopper II are all made of angle steel.

The further improvement of the technical solution of the present invention lies in that: the fixing bracket is provided with reinforcing ribs.

Owing to having adopted above-mentioned technical scheme, the technical progress that the present invention obtains is:

The efficiency of drilling with a fixed platform is more than 3 times higher than that of a vise, and the original loading and unloading is reduced from five times to one time. It saves time, thereby improving production efficiency, and the contact surface of the platform is large. During the drilling process, the channel steel is relatively stable, with a high safety factor, and it is not easy to drill in the air, so that the product quality of the pay-off block is guaranteed.

The pressing device can effectively prevent the upward arching phenomenon when multiple workpieces are placed flat in the drilling operation. The pressing strip passing through the pressing ring can be used to press the workpiece downwards, which can further improve the drilling accuracy; the supporting rod includes the first The first support rod and the second support rod are connected by threads, and the total height of the support rod can be adjusted arbitrarily, which is convenient for workpieces with different thicknesses and more flexible to use.

The compression ring is round or rectangular, which is easy to process and low in production cost; the base, stopper Ⅰ and stopper Ⅱ are all made of angle steel, which realizes waste utilization and further reduces production costs; The bearing strength and service life of the bracket.

detailed description

Below in conjunction with embodiment the present invention is described in further detail:

Example 1

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

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 the same base 1, the section of the compression strip 93 is also circular. Since five workpieces 6 need to be clamped, there are four support rods 91 on each base 1, and the compression of five workpieces 6 is realized by combining the stopper II 2 and the stopper II3. The distance between the support bars 91 corresponds to the width of the workpiece 6 .

When in use: the five workpieces 6 made of channel steel are lined up and arranged between the support rods 91, the space between the stopper 2 and the stopper Ⅱ3 just accommodates five workpieces 6, and the top of the jack 4 passes through the round hole 7 to clamp five workpieces 6 so that they are not easy to move, then for ensuring that the workpieces 6 do not arch upwards, the available compression strip 93 can pass the compression ring 92 to carry out the compression of the workpieces 6, so that five holes can be drilled simultaneously. And this platform contact surface is big, and in drilling process, because the workpiece 6 that channel steel is made is relatively stable, and safety factor is high, and it is difficult to drill eccentricity, and the product quality of pay-off block is guaranteed. After the drilling is completed, it is only necessary to extract the compression strip 93 from the compression ring 92.

The drilling efficiency of the invention is improved by more than 3 times than that of the vise drilling, and the original five times of loading and unloading are reduced to one time. Time is saved, which increases productivity.

Example 2

The difference between this embodiment and Embodiment 1 is: referring to FIG. 3 , the support rod 91 includes a first support rod 101 fixedly connected to the base 1 and a second support rod 102 screwed to the first support rod 101 , the second support The rod 102 is provided with a rectangular pressing ring 92, and the section of the pressing bar 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.
