Description

A channel steel door pedal side porous tapping assembly

technical field

The invention relates to the field of tapping equipment, in particular to a multi-hole tapping assembly for the side part of a channel steel door pedal.

Background technique

Tapping equipment is a kind of mechanical processing equipment for processing internal threads for workpieces. The existing tapping equipment generally includes a motor and a tapping head. Generally, the motor and the tapping head can only move up and down in the vertical direction. The motor is driven to rotate to achieve the effect of tapping the workpiece, but for individual workpieces, such as the C-shaped workpiece of channel steel products, as shown in Figure 4, in the process of tapping on both sides of the workpiece, The workpiece needs to be placed sideways, such as in a "crawl" type. If the vertical tapping method is used, the workpiece will be easily deformed by force, which will affect the accuracy of tapping. The operation is cumbersome, which is not conducive to improving work efficiency.

Therefore, further improvement is required.

Detailed ways

The present invention will be further described below with reference to the accompanying drawings and embodiments.

Referring to Figures 1 to 3, the multi-hole tapping assembly on the side of the channel steel door pedal includes a tapping motor 1, a moving base 2 and a fixed base 3. The tapping motor 1 is provided with a horizontal and horizontal tapping head 4. The tapping motor 1 moves back and forth along the length of the tapping head 4 on the moving base 2 through the first displacement mechanism, and the moving base 2 moves back and forth horizontally and longitudinally on the fixed base 3 through the second displacement mechanism. The tapping head 4 arranged horizontally and horizontally cooperates with the tapping motor 1, under the action of the first displacement mechanism, the tapping head 4 can tap the side of the workpiece in the horizontal direction, and the workpiece does not need to be placed sideways , reduce the chance of compression deformation, improve the accuracy of the side tapping of channel steel products, and at the same time, the second displacement mechanism can make the tapping head 4 can perform continuous tapping at a short distance, without frequent adjustment of the workpiece position, and improve work efficiency .

Further, the first displacement mechanism is a drive screw 21 arranged on the moving base 2 and used to displace the tapping motor 1 as a whole. The drive screw 21 and the tapping head 4 are driven by a sprocket device (not marked in the figure). Connection, the tapping motor 1 can drive the transmission screw 21 to rotate at the same time through the sprocket device, no additional drive motor is required, and the product structure is simplified. Different rotational speed ratios can be formed between the screws 21 according to the actual situation.

Further, the second displacement mechanism is the cylinder block 31 arranged on the fixed base 3 and used to displace the movable base 2 as a whole.
