The invention relates to the field of wood processing, in particular to a wood perforating device for a table.

Background

The table is a piece of furniture commonly used in our lives, such as a desk for students, a dining table for home use, a desk for office use and the like, and most of the desks are wooden. The table generally includes a table top and table legs coupled to each other, and particularly, the table top is provided with holes into which ends of the table legs are inserted, and the table legs and the table top are fixed together using glue or screws after the ends of the table legs are inserted into the holes of the table top.

In the prior art, holes in a table plate need to be machined on a drilling and milling machine, a plurality of holes need to be machined in the table plate during machining, after one hole is machined, the relative position between the table plate and a drill needs to be manually moved, and then the drill is used for drilling other positions of the table plate. The movement of the table plate needs to be manually pushed, so that the table plate is labor-consuming. In addition, when the table plate moves on the processing table, a certain friction exists between the table plate and the processing table, the processing table is easy to scratch the table plate, and the scratch needs to be repaired in subsequent processing, so that the cost of wood processing is increased.

Disclosure of Invention

The invention aims to provide a wood perforating device for a table, which is used for realizing the automatic movement of table board wood on a processing table without manual pushing.

In order to achieve the purpose, the technical scheme of the invention is as follows: a wood punching device for a table comprises a processing table, a vertically moving drilling machine and a first air cylinder for pushing the drilling machine to move, wherein the drilling machine is located above the processing table, two clamping blocks are connected to the processing table in a sliding mode, telescopic rods are connected to the two clamping blocks respectively, elastic pieces are arranged on the telescopic rods respectively, wedge blocks are fixedly connected to one ends, away from the clamping blocks, of the telescopic rods, abutting rods are fixedly connected to air cylinder rods of the first air cylinder, one ends, away from the first air cylinder, of the abutting rods abut against the wedge blocks, and first reset pieces are connected to the wedge blocks; the wood processing machine also comprises two conveying mechanisms positioned above the processing table, and the two conveying mechanisms intermittently convey the wood.

The working principle of the scheme is as follows: the processing table is used for supporting the wood. The drilling machine is used for driving the drill bit to rotate, and the first air cylinder is used for pushing the drilling machine to vertically move. The clamping block is used for clamping wood. When drilling, first cylinder promotes the rig and is close to timber, and first cylinder makes the offset rod be close to the voussoir simultaneously, and the one end that first cylinder was kept away from to the offset rod offsets with the voussoir, and the offset rod promotes the voussoir and removes, and the voussoir drives two grip blocks through the telescopic link and is close to each other, and two grip blocks carry out the centre gripping to timber to more stable when making drilling, prevent timber skew, improved the precision of drilling. When offset the pole and promote the voussoir and remove, hold power with the first piece that resets that the voussoir is connected, after drilling finishes, first cylinder drives rig antiport, and the drill bit of rig is extracted from the hole that timber was bored, and after offset the pole and leave the voussoir, first piece that resets made voussoir antiport, and the voussoir drives the grip block through the telescopic link and keeps away from timber, and the grip block loosens timber to make timber can freely move. The conveying mechanism is used for conveying the wood to move, and the conveying mechanism is intermittently conveyed, so that when the clamping blocks clamp the wood, the conveying mechanism is in a static state, and the conveying mechanism does not convey the wood; after the clamping block is separated from the wood, the conveying mechanism conveys the wood to move forwards, so that the automatic movement of the wood is realized, and the wood does not need to be manually pushed to move.

When the technical scheme is adopted, the method has the following effects:

1. during drilling, the clamping blocks clamp the wood, so that the wood is prevented from deviating, the stability of drilling is ensured, and the precision of drilling is improved.

2. Two voussoirs make the grip block to being close to when timber direction removes, after grip block and timber offset, the grip block can't continue to remove again, and the voussoir still is in the moving state under the effect of pole that supports mutually this moment, the voussoir makes the telescopic link shrink, first elastic component on the telescopic link holds power to guaranteed that the voussoir lasts and is in the moving state, and then guaranteed that the pole that supports can last vertical removal, make first cylinder can drive the rig to removing to being close to timber direction, guaranteed that the rig normally advances a knife.

3. This scheme need not the manual work and removes timber, loosens the back when the grip block, and transport mechanism conveys timber to make ligneous automatically move, make ligneous other positions relative with the drill bit of rig, be convenient for drill to ligneous other positions. When the wood is clamped for drilling, the conveying mechanism is in a static state, so that the wood is ensured to be in the static state, and the drilling machine can drill holes on the wood normally.

Furthermore, the two conveying mechanisms comprise moving blocks, a plurality of driving wheels are arranged on the moving blocks, and the moving blocks on the two conveying mechanisms are opposite. When the clamping blocks are loosened, the two conveying mechanisms are close to each other, the wood side parts of the driving wheels on the moving blocks are attached to each other, the driving wheels clamp the wood side parts, and the driving wheels drive the wood to convey through friction force.

Further, the vertical sliding connection has the ejector pad on the processing bench, and the below of ejector pad is equipped with rotatable bent axle, is connected with the connecting rod between the connecting rod axle journal of bent axle and the bottom of ejector pad, and the both ends of connecting rod rotate respectively to be connected on the bottom of ejector pad and the connecting rod axle journal of bent axle, and the top of ejector pad can offset with timber. When the crankshaft rotates, the crankshaft drives the push block to vertically reciprocate on the processing table through the connecting rod. By controlling the sliding speed and frequency of the push block, when the clamping block loosens the wood, the top of the push block penetrates out of the top of the processing table and moves upwards, and when the conveying mechanism conveys the wood, the top of the push block is separated from the wood. Therefore, after drilling is finished, the clamping block loosens the wood, the push block moves upwards, and the push block pushes the wood upwards to enable the wood to move upwards. When timber moved between two transport mechanism, made two transport mechanism be close to each other, two transport mechanism carry out the centre gripping to timber, then the ejector pad moves down, the top and the timber separation of ejector pad, timber is in unsettled state under two transport mechanism's centre gripping, and timber conveys forward under transport mechanism's conveying. When making timber conveying through this scheme, timber and processing platform separation, the processing platform can not mark the scar with ligneous bottom, does benefit to subsequent processing of timber, need not the later stage and restores timber.

Further, a cavity is arranged in the push block, an opening is formed in the top of the push block, a leakage opening is formed in the side portion of the push block, a rotatable rotating wheel is arranged at the bottom of the push block, a sliding rod is connected onto the leakage opening in a sliding mode, a discharging block is arranged at one end, located in the cavity, of the sliding rod, a rope is connected between one end, located outside the cavity, of the sliding rod and the connecting rod, and the rope spans the rotating wheel; the slide bar is connected with a second reset piece. From this, the saw-dust that drilling produced can enter into the cavity from the opening at ejector pad top and collect, and the saw-dust that enters into in the cavity is discharged from the leak again, compares traditional processing platform, and the saw-dust can not be deposited on the processing bench, and the saw-dust can in time be discharged for the processing environment is better. The bent axle rotates the in-process, drives the connecting rod reciprocating swing, and the slide bar resets under the combined action of piece and rope and reciprocating motion on the leak at the second, and the slide bar drives row material piece reciprocating motion, arranges the material piece and dredges the cavity, prevents that the saw-dust from piling up in the cavity, does benefit to the saw-dust and discharges from the cavity.

Further, a collecting box is arranged below the crankshaft. The collecting box is used for collecting the discharged sawdust.

Furthermore, the discharging block is wedge-shaped, and the inclined plane of the discharging block faces the cavity. Therefore, when the discharging block slides from the leakage opening to the cavity, the wood chips can move upwards by the inclined surface on the discharging block, and the wood chips in the cavity are prevented from blocking the discharging block from sliding from the leakage opening to the cavity. When the discharging block slides towards the direction of the leakage opening from the cavity, the plane on the discharging block is abutted against the wood chips in the cavity, so that the wood chips are pushed out, and the wood chips are more easily discharged from the cavity.

Further, the bottom of the cavity is obliquely arranged. Therefore, the sawdust in the cavity can slide along the inclined plane at the bottom of the cavity, and the sawdust is favorably discharged from the cavity.

Furthermore, the two ends of the crankshaft are connected with rotating rollers, steel wire ropes are wound on the rotating rollers, one ends, far away from the rotating rollers, of the steel wire ropes are fixedly connected to the abutting rods, torsional springs are connected to the rotating rollers, and one-way bearings are connected between the rotating rollers and the crankshaft. Therefore, when the abutting rod moves upwards, the abutting rod pulls the rotating roller to rotate through the steel wire rope, the rotating roller drives the crankshaft to rotate through the one-way bearing, and meanwhile, the torsion spring on the rotating roller stores force. When the abutting rod moves downwards, the steel wire rope does not move upwards any more, the rotating roller rotates reversely under the action of the torsion spring and rewinds the steel wire rope, and the rotating roller rotates reversely, so that the rotating roller cannot drive the crankshaft to rotate under the action of the one-way bearing, and is in an idle rotation state, so that the directional rotation of the crankshaft is realized, and the stable rotation of the crankshaft is ensured.

Further, the elastic part is a pressure spring. The pressure spring is a common elastic part and is easy to configure.

Further, the first piece that resets is first extension spring, and the second resets and is the second extension spring. The first tension spring and the second tension spring are common resetting pieces and are easy to configure.

The specific implementation process is as follows: the wood is placed on the processing table 12, the first air cylinder 1 and the drilling machine 2 are started, the drilling machine 2 drives the drill bit 7 to rotate, the first air cylinder 1 drives the drilling machine 2 to move downwards, and therefore the cutting feed of the drill bit 7 is achieved. Simultaneously, the cylinder rod of the first cylinder 1 drives the abutting rod 3 to move downwards, the wheel 5 on the abutting rod 3 abuts against the inclined surface of the wedge block 6, the wheel 5 slides on the wedge block 6, the wheel 5 pushes the wedge block 6 to transversely slide, the two wedge blocks 6 are close to each other, the two wedge blocks 6 drive the two clamping blocks 9 to be close to each other through the telescopic rod 11, and the two clamping blocks 9 clamp the wood to fix. When the wood is clamped by the clamping block 9, the drill bit 7 is not in contact with the wood, the two wedge blocks 6 are still in a state of being close to each other, the telescopic rod 11 is mutually contracted under the extrusion of the clamping block 9 and the wedge blocks 6, the elastic piece 10 generates elasticity, and the elastic piece 10 extrudes the clamping block 9, so that the clamping block 9 is clamped more tightly. At the same time, the wedge 6 makes the first reset piece generate elasticity and accumulate force. As the drilling machine 2 continues to move downwards, the drill bit 7 of the drilling machine 2 comes into contact with the wood, thereby drilling a hole in the wood.

After drilling is finished, the first cylinder 1 is enabled to move upwards in the reverse direction, and the first cylinder 1 drives the drilling machine 2 to move upwards, so that tool retracting of the drill bit 7 is realized. When the cylinder rod of first cylinder 1 upwards removed, the cylinder rod of first cylinder 1 drove and supports 3 rebound of pole mutually, and wheel 5 separates with voussoir 6 gradually, and voussoir 6 resets under the elastic action of first piece that resets, and two voussoir 6 keep away from each other, and two voussoir 6 drive two grip blocks 9 through telescopic link 11 and keep away from each other, and two grip blocks 9 loosen timber. Meanwhile, the steel wire rope 4 is pulled upwards by the abutting rod 3, the steel wire rope 4 drives the rotating roller 16 to rotate, the rotating roller 16 enables the torsion spring to store force, the rotating roller 16 drives the crankshaft to rotate under the action of the one-way bearing, the crankshaft drives the connecting rod 15 to swing up and down, left and right in a reciprocating mode, and the connecting rod 15 intermittently drives the pushing block 13 to move up and down in a reciprocating mode. The storage force of the torsion spring is that when the counter rod 3 moves downwards, the torsion spring drives the rotary roller 16 to rotate reversely, so that the steel wire rope 4 is wound and wound.

When the push block 13 moves upwards, the push block 13 pushes up the whole wood upwards, so that the wood is lifted, a certain gap is formed between the wood and the processing table 12, then the second air cylinder is controlled manually, the second air cylinder pushes the two conveying mechanisms 8 to be close to each other, the two moving blocks 20 are close to each other, the driving wheels 21 on the moving blocks 20 clamp the wood, and after the wood is clamped stably, the second air cylinder stops moving. When the push block 13 moves downwards, because the wood is clamped by the two conveying mechanisms 8, the wood is separated from the push block 13, the wood is in a suspended state, the motor on the moving block 20 is started at the moment, the motor on the moving block 20 drives the driving wheel 21 to rotate, and the driving wheel 21 enables the wood to move, so that the automatic movement of the wood is realized, and manual pushing is not needed. After the wood moves for a certain distance, the driving wheel 21 stops rotating, and the wood stops moving. And the two transfer mechanisms 8 are kept away from each other by the second air cylinder, the two transfer mechanisms 8 loosen the wood, and the wood falls on the processing table 12 under the action of gravity. The drilling machine 2 is then moved downwards again to drill another hole in another part of the wood. In the downward movement process of the drilling machine 2, the steel wire rope 4 becomes loose, the rotary roller 16 rotates reversely under the action of the torsion spring, and the rotary roller 16 winds the steel wire rope 4. Since the roller 16 rotates in the reverse direction, the roller 16 does not rotate the crankshaft through the one-way bearing.

In the drilling process, can produce some saw-dusts, because the top of ejector pad 13 is equipped with the opening, the saw-dust accessible opening that so produced falls into the cavity of ejector pad 13 to along the inclined plane of cavity bottom from the leak mouth 14 come out and leak into to collection box 18, thereby realized the collection of saw-dust, prevent that the saw-dust from piling up on processing platform 12, do benefit to the automatic clearance of saw-dust.

In addition, when the connecting rod 15 swings left and right reciprocally on the pushing block 13, the connecting rod 15 will pull the rope 27 reciprocally, and the sliding rod 24 will slide reciprocally under the combined action of the second restoring member 26 and the rope 27. When the sliding rod 24 slides in a direction approaching the second restoring member 26, the sliding rod 24 pushes the discharging block 25 to move upward, and the discharging block 25 pushes the chips upward due to the inclined surface of the discharging block 25, so that the chips do not obstruct the upward movement of the discharging block 25. When the sliding rod 24 slides away from the second restoring member 26, the sliding rod 24 pulls the discharging block 25 downwards, and the vertical plane of the discharging block 25 abuts against the wood chips, so that the wood chips are pushed out from the discharge opening 14, the discharging of the wood chips is facilitated, and the discharge opening 14 is prevented from being blocked due to the fact that the wood chips are interwoven together.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, it is possible to make various changes and modifications without departing from the concept of the present invention, and these should be construed as the scope of protection of the present invention, which will not affect the effect of the implementation of the present invention and the utility of the patent.
