Description

A fast measuring device for the distance between clamp holes of equipment

technical field

The invention belongs to the field of electrical equipment, mainly to overcome the poor contact caused by cumbersome measurement methods and inaccurate positioning of the hole distance when marking the line clip on the equipment to determine the bolt hole distance, and the connection is likely to cause heat and other problems. The invention relates to a device for quickly measuring the distance between clamp holes of equipment.

Background technique

"Key Measures for Preventing Heating of Conductors and Joints" requires that when installing bolted joints, the bolt specifications, quantity and drilling size must not be changed arbitrarily to ensure that the pressure applied by the bolts to the contact surface is within an appropriate range. At present, the distance between the clamp holes of the equipment is measured by using a steel ruler. Each wire clamp needs to measure its length and width with a steel ruler, calculate its center position, calculate the new position of the bolt hole according to the center position, and determine it with two straight lines parallel to the length and width. On the one hand, this method needs to calculate the position of the center and each point, which is cumbersome and not simple enough; on the other hand, when the line is drawn to determine the bolt hole distance, the straight line is easily not parallel to the two sides, so that it is easy to be deflected when the clamp is overlapped. The problem is that it cannot make qualified and good contact with the terminal board, which may easily cause heat and other problems.

Patent CN104175306A discloses a hole distance positioning device for equipment clamps. This device uses a main ruler with a vernier and a marking body for measurement. When using it, it is necessary to measure the position between the two holes of the connecting plate and record the value. Then position the value with the vernier on the main scale, lock the vernier, push out the main scale in parallel, use the marking body corresponding to the vernier to draw a line on the equipment clip, record at least two sets of values, and draw a well on the equipment clip. The intersection point of the word line is the position of the machining hole. This method requires multiple measurements and positioning, which brings large errors. During operation, it is necessary to draw multiple positioning lines vertically and horizontally on the wire clip, and the process is also relatively cumbersome. the

Patent CN203672267U discloses a wire clip punching and positioning measuring device, which is mainly composed of a main ruler and a moving ruler. The position of the punching hole is determined by the lateral displacement. This method has defects such as inaccurate positioning of the center distance and errors caused by multiple positioning.

The above two methods still fundamentally do not break away from the limitation of the thinking method of using a ruler to draw a line to measure.
