Description

Explosion-proof switch shutting bent plate drilling tool

Technical Field

The utility model belongs to the technical equipment field of explosion-proof electrical apparatus, concretely relates to drilling frock of shutting bent plate on explosion-proof switch.

Background

Explosion-proof switches for underground coal mines are basically provided with mechanical locking devices, and the most common and most common explosion-proof switches are mechanically locked by means of a locking rod moving in a locking bent plate. However, this method requires a high concentricity between the threaded hole and the through hole at both ends of the locking bent plate, and the concentricity determines the reliability and flexibility of the locking method. When the length of the locking bent plate is about 200mm, the requirement of the concentricity of the through hole and the threaded hole of the locking bent plate on the concentricity is difficult to guarantee because the locking bent plate cannot be processed by a conventional method (a drill drills another hole through one hole).

Disclosure of Invention

The utility model aims at eliminating the defects of the prior art and providing an explosion-proof switch locking bent plate drilling tool.

In order to achieve the purpose, the utility model adopts the technical proposal that: the utility model provides an explosion-proof switch shutting bent plate drilling frock which characterized in that: a vertical plate is fixed in the middle of the base, a rib plate is arranged on the back surface of the vertical plate, and the rib plate is fixed on the base; a support shaft is arranged at the front side of the middle part of the vertical plate, and a limit plate A is arranged at the rear side; the guide shaft is arranged between the support shaft and the limiting plate A and is fixed on the vertical plate through an upper shaft sleeve arranged at the upper end of the guide shaft and a lower shaft sleeve arranged at the lower end of the guide shaft; the guide sleeve is riveted with the guide block and then fixed with the vertical plate; the front end of the baffle is vertically connected with the supporting shaft and is fixed by a nut, and the rear end of the baffle is embedded into the clamping groove of the limiting plate A.

A gap is reserved between the guide block and the upper shaft sleeve, and the height of the gap is equal to the thickness of the locking bent plate; and limiting plates B are arranged on the two sides of the guide block and the upper shaft sleeve.

A bolt is arranged in the middle of the baffle plate and used for connecting and fixing the locking bent plate; the guide shaft is provided with a handle.

The working principle is as follows: positioning the locking bent plate 16 by using the guide shaft 8; fixing a locking bent plate 16 by using a baffle plate 10 and a fastening bolt 11; the bottom hole of the threaded hole 19 on the locking bent plate 16 is drilled by utilizing the guiding function of the guiding sleeve 4, so that the concentricity requirement of the through hole 18 on the locking bent plate 16 and the threaded hole 19 is realized.

The utility model has the advantages that: the locking bent plate is simple in structure and flexible to operate, and the requirement that the concentricity of the through hole and the threaded hole on the locking bent plate is met. The processing procedure is simplified, the processing difficulty is reduced, the reliability is good, and the production efficiency is greatly improved.

Detailed Description

The principles and features of the present invention are described and illustrated in the following drawings.

Embodiment 1, see fig. 1-3, an explosion-proof switch shutting bent plate drilling frock, its characterized in that: a vertical plate 3 is fixed in the middle of the base 1, a rib plate 2 is arranged on the back surface of the vertical plate 3, and the rib plate 2 is fixed on the base 1; a supporting shaft 7 is arranged at the front side of the middle part of the vertical plate 3, and a limiting plate A14 is arranged at the rear side; the guide shaft 8 is arranged between the support shaft 7 and the limit plate A14 and is fixed on the vertical plate 3 through an upper shaft sleeve 6 arranged at the upper end of the guide shaft and a lower shaft sleeve 9 arranged at the lower end of the guide shaft; the guide sleeve 4 is riveted with the guide block 5 and then fixed with the vertical plate 3; the front end of the baffle plate 10 is vertically connected with the supporting shaft 7 and fixed by a nut 12, and the rear end is embedded into a clamping groove of the limiting plate A14. A gap is reserved between the guide block 5 and the upper shaft sleeve 6, and the height of the gap is equal to the thickness of the locking bent plate 16; and limiting plates B15 are arranged on two sides of the guide block 5 and the upper shaft sleeve 6. A bolt 11 is arranged in the middle of the baffle 10; the guide shaft 8 is provided with a handle 13.

The locking bent plate 16 is processed as follows:

blanking, punching a through hole, bending, drilling a bottom hole of a threaded hole by using a drilling tool, and tapping. Referring to fig. 4-6, the guide shaft 8 is moved upward by the handle 13, the locking bent plate 16 is placed in the corresponding position of the tool drilling tool, the guide shaft 8 is moved downward to pass through the through hole 18 of the locking bent plate 16 to return to the initial state, the baffle 10 is rotated to enable one end of the baffle to be embedded into the clamping groove of the limiting plate a14, finally the locking bent plate 16 is fixed by the bolt 11 of the baffle 10, and then the drill bit 17 drills a hole in the locking bent plate 16 through the guide sleeve 4. Similarly, when the parts are disassembled, the operations are sequentially reversed.
