Description

Mechanical perforating machine for electric power construction

Technical Field

The invention belongs to the technical field of perforating machines, and particularly relates to a mechanical perforating machine for electric power construction.

Background

The multi-hole drill is commonly called a multi-hole drilling machine, a multi-shaft device, a multi-shaft drilling device or a multi-shaft head. Is a machine tool device applied to drilling and tapping in the mechanical field. The multi-hole drill has a single-sided drill, a double-sided drill and a multi-sided drill. The multi-hole drill is widely applied to drilling and tapping processing of multi-hole parts in the mechanical industry.

Porous parts such as conductive sheets and wiring bases used in sockets are often used in power construction; multi-hole drilling is often used in perforating these porous parts; the cutting speed exerted by the multi-hole drill on each drill bit during punching is basically consistent; during processing, it is common for the drill bit to break due to a mismatch in cutting speed and part strength, particularly for parts having differences in strength from orientation to orientation.

In the event of such a situation, it is necessary to stop the machine to remove the broken drill bit; after the processing of the rest holes being processed is completed, the holes which cannot be processed due to the breakage of the drill bit and the subsequent holes to be processed are recombined into a group of processing holes to be processed or the holes are processed independently. In the re-machining process, if the drill bit corresponding to the machined hole and the drill bit corresponding to the rest of the unprocessed holes start to be machined at the same starting position, the resistance of the drill bit corresponding to the rest of the unprocessed holes is slowly increased along with the increase of the depth of the holes; when the drill bit is contacted with the processing surface in the hole, the resistance of the drill bit is suddenly increased, and the drill bit is broken again; if the machined hole is machined from the machined surface in the hole, the rest of the holes are not finished after the machining of the hole is finished, and the idle running phenomenon of the drill bit corresponding to the machined hole occurs.

The invention designs a mechanical perforating machine for electric power construction, which solves the problems.

1. according to the invention, when punching is positioned, the first motor, the second motor, the third motor and the sixth motor can be controlled to work according to the position of a punching point and the punching angle; ensuring the accuracy of positioning each drill bit.

2. According to the invention, when the first motor drives the third gear to rotate for circumferential positioning, the fifth gear and the second gear can be separated through the designed transmission plate and the L-shaped transmission rod, namely, the transmission of the fourth gear and the drill bit is disconnected; the drill bit is not driven to rotate, so that the drill bit and peripheral components are protected.

3. In the invention, when the hole which is already drilled but is not completely drilled due to the fracture of the drill bit is drilled, the drill bit is positioned on the machining surface of the machined hole; thus, the machined Kong Jiuyou is possibly finished before other holes which are not machined but are machined together with the holes in groups, when the situation occurs, the electric push rod can control the round sleeve to move towards the side far away from the mounting disc after receiving a punching finishing signal, the round sleeve drives the first rotating shaft to move, the first rotating shaft drives the fifth gear to slide and separate from the second gear, namely, the transmission of the drill bit is disconnected, and the drill bit is prevented from idling.

6. When the hole is punched on the right lower side of the part, the two arc-shaped sliding rails can be symmetrically positioned on the lower side of the mounting plate, and then one sliding mounting block on the two arc-shaped sliding rails is controlled to drive the drill bit to move to the middle of the two arc-shaped sliding rails, so that the drill bit is right opposite to the right lower side of the part.

When the first motor 4 drives the third gear 15 to rotate for circumferential positioning, the fourth gear 16 arranged on the sliding shell 3 also rotates relative to the gear ring 7, so that the input rotating shaft 5 is not driven to rotate, and the gear ring 7 is in a static rotating state, so that the fourth gear 16 is driven to rotate under the action of the gear ring 7, the fourth gear 16 drives the fifth gear 20 to rotate through the second rotating shaft 9 and the second gear 14, and then drives the drill bit 63 to rotate, so that the drill bit 63 scratches peripheral components; in order to prevent the situation, two transmission plates 21 are arranged on two sides of the third gear 15, when the third gear 15 rotates, the tooth area 24 on one transmission plate 21 of the two transmission plates 21 is driven to slide by the third gear 15, the transmission plate 21 slides to drive an L-shaped transmission rod 23 to slide, the L-shaped transmission rod 23 slides to stir the installation sliding block 17 to slide, the installation sliding block 17 drives the first rotating shaft 8 to slide towards the side far away from the installation disc 1, and the first rotating shaft 8 slides to drive the fifth gear 20 to slide to be separated from the second gear 14, namely, the transmission of the fourth gear 16 and the drill bit 63 is disconnected. The invention designs two transmission plates 21, the reason for the design is that no matter whether the sliding shell 3 rotates anticlockwise or clockwise around the mounting disc 1, one transmission plate 21 in the two transmission plates 21 is driven to slide all the time, so that the fifth gear 20 is separated from the second gear 14, and the tooth area 24 on the other transmission plate 21 is not meshed with the third gear 15 in the rotating direction, namely the rotation of the other transmission plate 21 and the third gear 15 is not influenced; in addition, in the invention, the L-shaped transmission rod 23 is positioned in the square notch 22 formed on the installation slide block 17, and in the initial state, the L-shaped transmission rod 23 is in contact fit with one side of the square notch 22 away from the installation disc 1, and a gap is formed between the L-shaped transmission rod 23 and the other side of the square notch 22, namely, when one L-shaped transmission rod 23 is shifted to slide by the installation slide block 17, the other L-shaped transmission rod 23 does not influence the sliding of the installation slide block 17.

In the present invention, when a hole which has been drilled but is not completely drilled due to breakage of the drill 63 is drilled, the drill 63 is positioned on the machining surface of the hole to be machined; the machined Kong Jiuyou may finish machining before other holes which are not machined but machined together with the holes in groups, and when the situation occurs, the electric push rod 19 controls the round sleeve 18 to move towards the side far away from the mounting disc 1 after receiving a punching finishing signal, the round sleeve 18 drives the first rotating shaft 8 to move, the first rotating shaft 8 drives the fifth gear 20 to slide and separate from the second gear 14, namely, the transmission of the drill 63 is disconnected, and the drill 63 is prevented from idling.

In the process of sliding the fixed sliding block 59 along the vortex sliding rail 61 from outside to inside in the circumferential direction, the circumference of the vortex sliding rail 61 from outside to inside is gradually reduced, namely, the distance that the winding cloth 60 can be pulled to move by one rotation of the transmission deflector rod 58 is gradually reduced, the rotation speed of the winding wheel 55 is gradually reduced, the feeding speed of the drill 63 is gradually increased along with the depth of punching, and the feeding speed is gradually reduced.

When a hole that has been drilled but has not been completely drilled due to breakage of the drill 63 is drilled, the drill 63 will be positioned on the machined surface of the machined hole, while the remaining drill 63 is on the original machined surface; positioning the drill 63 on the machining surface of the machined hole by the fifth motor 43 at the time of positioning; when the drilling is started, the feeding speed corresponding to the drill 63 is the feeding speed corresponding to the depth, and the drilling resistance of the drill 63 is increased and the drill is broken again because the feeding speed of the drill 63 is not the same as the feeding speed of the rest of the drills 63.

During the punching process, the resistance of the drill bit 63 is related to the punching depth, the rotation speed of the drill bit 63 and the feeding speed of the drill bit 63, and the rotation speeds of the drill bits 63 are basically the same because the rotation speeds of the drill bits 63 are uniformly provided by the input rotating shaft 5 in the invention; under the condition that the rotation speed is unchanged in the punching process of the drill bit 63, the deeper the punching, the slower the feeding speed can be realized through the designed structure, and the drill bit 63 is protected to a certain extent.

The fourth motor 42 of the invention can drive the inner end of the vortex slide rail 61 to rotate, so that the circumference of a single circle of the vortex slide rail 61 is changed, the distance required to move when the winding cloth 60 is wound on the vortex slide rail 61 for one circle is correspondingly changed, and the feeding speed of the drill bit 63 is also changed; thus, when parts with different hardness are used, different feeding speeds can be selected, namely, the multi-hole drill designed by the invention can select proper feeding speed according to the hardness of the parts under the condition that the rotation speed of the drill bit 63 is unchanged.

The arc-shaped slide rail 26 designed by the invention consists of two parts, namely a fixed section 30 at the upper end and a swinging section 31 at the lower end, wherein the swinging section 31 at the lower end can swing relative to the fixed section 30 at the upper end, and the reason for the design is that when a part is placed on the lower side of the installation plate 1, the lower end of the interfered arc-shaped slide rail 26 can swing for a certain angle, so that the part is placed on the lower side of the installation plate 1; in normal use, the swinging section 31 and the fixed section 30 are fixedly connected through the bolt 32, so that the sliding of the sliding mounting block 29 is not affected.

When the hole is punched on the right lower side of a part, the two arc-shaped slide rails 26 can be symmetrically positioned on the lower side of the mounting plate 1, and then one sliding mounting block 29 on the two arc-shaped slide rails 26 is controlled to drive the drill bit 63 to move to the middle of the two arc-shaped slide rails 26, so that the drill bit 63 is right opposite to the right lower side of the part; the present invention has two second motors 33 and four eighth gears 39 provided on the slide mount blocks 29, so designed because, in the case of the above-described case, when the lower end of the slide mount block 29 to be used moves from the corresponding arc slide rail 26 to the other arc slide rail 26, the two eighth gears 39 located on the front side are disengaged from the corresponding arc slide rail 26, but the other two eighth gears 39 are not; after the two eighth gears 39 on the front side are engaged with the other arc-shaped slide rails 26, the other two eighth gears 39 are not separated from the corresponding arc-shaped slide rails 26 yet, and the used sliding mounting block 29 is supported between the two arc-shaped slide rails 26.

The function of the pneumatic hold-down mechanism 41 is to further secure the positioned slide mounting block 29.
