Description

Technical Field

[0001] The present invention belongs to the technical field of electric power maintenance equipment, and particularly relates to a hole pitch positioning device. Background Art

[0002] A wire clamp is an iron or aluminum metal accessory fixed on a wire, mainly used for fixing or connecting the wire. Wire clamps can be mainly divided into types such as equipment wire clamps, fuse wire clamps, wire holding clamps, terminal wire clamps, puncture earthing wire clamps, and tension clamps. Among them, equipment wire clamps are mainly used for the connection of the outgoing line terminals of the substation busbar lead and electrical equipment (such as transformers, circuit breakers, disconnectors, wall bushings, etc.), or for the electrical connection between primary equipment. Due to the differences in primary equipment, the hole pitches required for equipment wire clamps are also different. Therefore, equipment wire clamps are not punched at the factory, but the dimensions are measured on the wire clamp according to needs on site, and then punched. And a large number of equipment wire clamps need to be used, and their sizes are various. Manually scribing for hole pitch positioning not only has low efficiency, high work intensity, but also low accuracy. Therefore, it is very necessary to develop a convenient-to-use hole pitch positioning device. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a hole pitch positioning device with reasonable structure, convenient use, and capable of quickly positioning the hole pitch of equipment wire clamps of different sizes according to needs.

[0004] The purpose of the present invention is achieved as follows: A hole pitch positioning device includes a first fixing rod. The right side surface of the top of the first fixing rod is fixedly connected with a second fixing rod. A first sliding groove is arranged in the middle and lower part of the first fixing rod. The first sliding groove is slidably connected with a guiding slider. The top of the guiding slider is fixedly connected with a first connecting slide plate. The first connecting slide plate is fixedly connected with a left slider. Teeth are arranged on the lower right side surface of the first fixing rod. The right side of the bottom surface of the first fixing rod is fixedly connected with a first supporting plate. A second sliding groove is arranged on the right side inside the second fixing rod. The second sliding groove is slidably connected with the guiding slider. The top of the guiding slider is fixedly connected with a second connecting slide plate. The second connecting slide plate is fixedly connected with a sliding rod. Teeth are arranged on the lower part of the lower side surface of the second fixing rod. The bottom surface of the second fixing rod is fixedly connected with a second supporting plate. A third sliding groove is arranged inside the sliding rod. The third sliding groove is slidably connected with the guiding slider. The top of the guiding slider is fixedly connected with a third connecting slide plate. The third connecting slide plate is fixedly connected with a right slider. Teeth are arranged on the lower left side surface of the sliding rod. The bottom surface of the sliding rod is fixedly connected with a third supporting plate. Teeth are arranged on the lower part of the upper side surface of the left slider. Teeth are arranged on the lower part of the upper side surface of the right slider. The left slider and the right slider are connected by a telescopic rod. The hole pitch positioning device includes a gear. A through hole is arranged in the center of the gear. The gear can be meshed with the teeth.

[0005] The overall shape of the guiding slider is rectangular, and the left and right ends of the guiding slider are arc-shaped. Correspondingly, both ends of the first chute, the second chute, and the third chute are arc-shaped.

[0006] A first locking bolt is connected to the side of the guiding slider. Correspondingly, locking through grooves are provided inside the first fixing rod, the second fixing rod, and the sliding rod. The first locking bolt is slidably connected to the locking through groove, and the first locking bolt is threadedly connected to the guiding slider.

[0007] A second locking bolt is threadedly connected to the bottom of the guiding slider.

[0008] A locking slider is fixedly connected to the bottom of the guiding slider, and a third locking bolt is threadedly connected to the top of the guiding slider. The third locking bolt penetrates the first connecting slide plate, the second connecting slide plate, and the third connecting slide plate corresponding to the guiding slider.

[0009] Two telescopic rods are provided. The left end of the telescopic rod is slidably connected to the left slider, and the right end of the telescopic rod is slidably connected to the right slider.

[0011] Advantages of the present invention: The main structure of the present invention includes a first fixing rod, a second fixing rod, a sliding rod, a left slider and a right slider. The left slider and the right slider are connected by a telescopic rod. The left slider and the right slider can slide along the first chute and the third chute respectively to adjust their distances from the second fixing rod, so as to adapt to equipment wire clips of different lengths and the requirements for different hole pitches. The sliding rod can slide along the second chute to adjust its distance from the first fixing rod to adapt to equipment wire clips of different widths and the requirements for different hole pitches.

According to different hole pitches required, gears of different sizes can be replaced, and the hole centers with corresponding hole pitches can be obtained in the same way. The structure of the present invention is reasonable, convenient to operate and use. It can position different hole pitches for equipment wire clips of different sizes as required, improving the work efficiency and the accuracy of hole pitch positioning and reducing the labor intensity.

[0029] For better effect, the overall shape of the guiding slider 17 is rectangular, and the left and right ends of the guiding slider 17 are arc-shaped. Correspondingly, both ends of the first chute 2, the second chute 8, and the third chute 11 are arc-shaped, which can provide better guiding and limiting effects for the left slider 3, the right slider 12, and the sliding rod 9 when sliding along their respective chutes, and improve the stability of the overall structure of the device.

[0030] In order to provide a locking effect before and after the sliding of the left slider 3, the right slider 12, and the sliding rod 9, a first locking bolt 24 is connected to the side surface of the guiding slider 17. Correspondingly, locking through grooves 23 are provided inside the first fixed rod 1, the second fixed rod 6, and the sliding rod 9. The first locking bolt 24 is slidably connected to the locking through groove 23, and the first locking bolt 24 is threadedly connected to the guiding slider 17.
