Description

Technical Field

[0001] This utility model relates to the field of drilling technology, and more specifically, to a dustproof drilling machine. Background Technology

[0002] A drilling machine is a machine tool that mainly uses a drill bit to machine holes in a workpiece. Usually, the rotation of the drill bit is the main motion, and the axial movement of the drill bit is the feed motion. During the machining process, the workpiece is stationary, while the cutting tool moves to align the center of the cutting tool with the center of the hole and rotates the cutting tool. The characteristic of a drilling machine is that the workpiece is fixed and the cutting tool rotates.

[0003] However, some existing drilling machines only fix the workpiece horizontally, lacking vertical constraints. This can lead to drill axis misalignment during drilling operations, affecting the verticality and positional accuracy of the hole. Furthermore, when drilling larger workpieces, vibration or movement can cause uneven stress on the drill bit, increasing wear and potentially even causing breakage. Additionally, the drilling process generates dust and debris, with metal shavings flying everywhere, impacting the processing environment. To avoid affecting subsequent workpiece processing, workers need to clean the area regularly, which is inconvenient, and the flying dust can negatively affect their health. Utility Model Content

[0004] The purpose of this invention is to provide a dustproof drilling machine to solve the above-mentioned problems.

[0005] To achieve the above objectives, this utility model provides a dustproof drilling machine, comprising: a support, a drilling machine body fixed to the top of the support, a support that is detachably fixed to the support by a clamp and used to support the workpiece, and a drill bit mounted on the drilling machine body;

[0006] The positioning parts are both mounted on the support and are arranged perpendicularly to each other.

[0007] A dustproof part is provided on the bracket and the support, and the dustproof part is located directly below the drill bit;

[0008] The clamping control part is detachably fixed to the bracket by a clamp, and the clamping control part is used to support and adjust the dustproof part.

[0009] The positioning part is used to restrict the movement of the workpiece on the support;

[0010] The height of the clamping part on the bracket is controlled, and the clamping part is driven to bring the dustproof part closer to the support.

[0011] Furthermore, the dustproof part includes a collection box fixed on the bracket, a dust removal fan whose air inlet end is connected to the collection box, a dust cover located directly below the drill bit and above the support, a slot opened on the top of the dust cover and adapted to the drill bit, an air inlet opened on the dust cover, and a first air supply pipe with one end connected to the dust cover and the other end connected to the collection box.

[0012] Furthermore, the dustproof part also includes an air supply groove with two openings at the bottom of the support, and a through groove on the upper surface of the support that communicates with the air supply groove.

[0013] Furthermore, the dustproof part also includes a dust collection hood that is fixed to the bottom of the support by bolts and covers one of the openings of the air supply channel, with one end connected to the dust collection hood and the other end connected to the collection box.

[0014] Furthermore, the clamping control unit includes a support rod fixed to the bracket by a clamp, a control cover fixed to the support rod and movably sleeved outside the dust cover, a control ring rotatably installed on the top of the dust cover, and a threaded ring fixedly sleeved outside the control ring and threadedly connected to the control cover;

[0015] A rubber pad is fixed to the bottom of the dust cover.

[0016] Furthermore, the positioning part includes a limiting groove formed on the support, a control screw rotatably installed in the support and the limiting groove, a positioning seat slidably installed in the limiting groove and threadedly connected to the control screw, and a positioning rod fixed to the top of the positioning seat.

[0017] Furthermore, the positioning part also includes a rotating handle hinged to one end of the control screw, which is disposed on the support and has a scale groove corresponding to the limiting groove.

[0018] Compared with the prior art, the embodiments of this utility model have the following beneficial effects:

[0019] This dustproof drilling machine can quickly position the workpiece on the support through its positioning part. Under the control of the clamping part, the dust cover in the dustproof part moves down to contact the workpiece, restricting the vertical movement of the workpiece. This ensures the stability of the workpiece during drilling, guarantees the verticality and positional accuracy of the drilled hole, and effectively avoids the workpiece from vibrating or moving, which could cause uneven force on the drill bit and damage when drilling larger workpieces.

[0020] This dustproof drilling machine, through the clamping and control unit, controls the dust cover in the dustproof section to move downwards and contact the workpiece to be processed. This allows the dust cover to effectively shield and protect the drilling position on the workpiece, thus preventing dust and debris from splashing when the drill bit passes through the slot in the dustproof section to drill the workpiece. With the cooperation of the dust removal fan, collection box, first air supply pipe, and second air supply pipe, negative pressure is generated in both the dust cover and the dust collection hood, carrying away dust and debris above and below the workpiece during drilling. This prevents the drilling process from affecting the processing environment. After drilling is completed, the operator does not need to clean the support, which facilitates the drilling operation and effectively reduces the impact on the operator's health.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0031] like Figure 1-6 As shown, a dustproof drilling machine includes: a support 1, a drilling machine body 2 fixed to the top of the support 1, a support 3 detachably fixed to the support 1 by a clamp and used to support the workpiece, and a drill bit 4 installed on the drilling machine body 2;

[0032] Positioning part 5, both of the two positioning parts 5 are mounted on the support 3, and the two positioning parts 5 are arranged perpendicularly to each other;

[0033] Dustproof part 6 is provided on the bracket 1 and the support 3, and the dustproof part 6 is located directly below the drill bit 4;

[0034] The clamping control part 7 is detachably fixed to the bracket 1 by a clamp, and the clamping control part 7 is used to support and adjust the dustproof part 6.

[0035] The positioning part 5 is used to restrict the movement of the workpiece on the support 3;

[0036] The height of the clamping part 7 on the bracket 1 is controlled, and the clamping part 7 is driven so that the dustproof part 6 is close to the support 3;

[0037] In use, according to the size data of the workpiece and the drilling position, the positions of the two positioning rods 26 on the two positioning parts 5 on the control support 3 are adjusted to change the space on the support 3 where the workpiece can be placed. Thus, when the workpiece is placed on the support 3 and simultaneously abuts against the two positioning rods 26, positioning can be completed quickly and the drilling position can be determined, which effectively improves the efficiency of batch drilling of workpieces. At the same time, the horizontal direction of the workpiece is restricted to a certain extent, which improves the stability of the workpiece during drilling.

[0038] After the workpiece is positioned, the clamping control unit 7 pushes the dust cover 10 in the dustproof unit 6 closer to and against the workpiece, thereby restricting the vertical movement of the workpiece, ensuring the stability of the workpiece during drilling, avoiding affecting the drilling accuracy of the workpiece, and preventing the workpiece from vibrating or moving, which could cause uneven force on the drill bit 4, increase the wear of the drill bit 4, or even cause the drill bit 4 to break. At the same time, according to the thickness of the workpiece, the height of the support 3 and the clamping control unit 7 on the bracket 1 is adjusted by the clamp so that the workpiece to be drilled placed on the support 3 is close to the drill bit 4, which makes it convenient for the drilling machine body 2 to control the drill bit 4 to perform drilling operation on the workpiece, and to control the dust cover 10 in the dustproof unit 6 to be close to the workpiece, but leaving a certain amount of space between them to facilitate the quick fixation of the material.

[0039] When the drill bit 4 passes through the slot 11 in the dustproof section 6 to drill a hole in the workpiece, the dustproof section 6 operates, and the dust removal fan 9 starts, creating negative pressure in the collection box 8. Through the connection between the first air supply pipe 13 and the second air supply pipe 17, negative pressure is generated in both the dust cover 10 and the dust collection cover 16. Because the dust cover 10 is in close contact with the workpiece and effectively protects the drilling position, air entering the dust cover 10 through the air inlet pipe and then entering the collection box 8 through the first air supply pipe 13 can carry away the air generated during drilling. Dust and debris above the workpiece are removed by air entering the air supply channel 14 through one opening and then through the other opening into the dust collection hood 16. The air then enters the collection box 8 through the second air supply pipe 17. This process removes dust and debris from below the workpiece during drilling, thus preventing dust and debris from splashing during drilling and affecting the processing environment. After drilling is completed, the operator does not need to clean the support 3, greatly improving the convenience of the device and effectively reducing the impact on the operator's health.

[0040] Optionally, the dustproof part 6 includes a collection box 8 fixed on the bracket 1, a dust removal fan 9 connected to the collection box 8 at its air inlet end, a dust cover 10 positioned directly below the drill bit 4 and above the support 3, a slot 11 on the top of the dust cover 10 and adapted to the drill bit 4, an air inlet 12 on the dust cover 10, and a first air supply pipe 13 connected at one end to the dust cover 10 and at the other end to the collection box 8. In use, the dust removal fan 9 is driven to extract air from the collection box 8, creating a negative pressure within the collection box 8, which in turn causes air to be drawn from the first air supply pipe 13. Negative pressure is generated inside the dust cover 10, allowing outside air to enter the dust cover 10 through the air inlet 12 and then be fed into the collection box 8 through the first air supply pipe 13. When the drill body 2 is working and the drill bit 4 is driven through the slot 11 to drill the workpiece, the dust and debris generated during drilling will be carried by the air entering the dust cover 10 through the air inlet 12 and transported to the collection box 8 for effective collection and storage. This prevents the dust and debris generated during drilling from flying everywhere and ensures a clean working environment, reduces the adverse effects on the cleaning work after drilling, and avoids the health of the workers from flying dust.

[0041] Optionally, the dustproof part 6 also includes an air supply groove 14 with two openings at the bottom of the support 3 and a through groove 15 connected to the air supply groove 14 on the upper surface of the support 3. When drilling part of the workpiece, the through groove 15 facilitates the lower end of the drill bit 4 to pass through the workpiece, and allows some of the dust and debris generated during drilling to fall into the through groove 15. At this time, air is extracted through one opening of the air supply groove 14, and air can enter the air supply groove 14 through the other opening, which can quickly remove the dust and debris located in the through groove 15.

[0042] Optionally, the dustproof part 6 also includes a dust collection hood 16 fixed to the bottom of the support 3 by bolts and covering one of the openings of the air supply channel 14, and a second air supply pipe 17 connected at one end to the dust collection hood 16 and at the other end to the collection box 8. In use, a negative pressure is generated in the dust collection hood 16 between the second air supply pipe 17 and the collection box 8. Dust and debris generated at the bottom of the workpiece during drilling will be sucked into the dust collection hood 16 through the air supply channel 14 and then transported to the collection box 8 for storage through the second air supply pipe 17.

[0043] Optionally, the clamping control unit 7 includes a support rod 18 fixed to the bracket 1 by a clamp, a control cover 19 fixed to the support rod 18 and movably sleeved outside the dust cover 10, a control ring 20 rotatably installed on the top of the dust cover 10, and a threaded ring 21 fixedly sleeved outside the control ring 20 and threadedly connected to the control cover 19.

[0044] The bottom of the dust cover 10 is fixed with a rubber pad 22. During use, by rotating the control ring 20, the dust cover 10 is pushed down under the restriction of the control cover 19 and comes into contact with the workpiece to be drilled. This clamps and fixes the workpiece between the dust cover 10 and the support 3. The rubber pad 22 at the bottom of the dust cover 10 ensures tight contact between the dust cover 10 and the workpiece, improving the stability of the workpiece during subsequent drilling with the drill bit 4 and reducing deviation. At the same time, it ensures the protective effect of the dust cover 10 on the workpiece drilling area, effectively preventing dust and debris from flying everywhere. Before use, the height of the support rod 18 and the control cover 19 on the bracket 1 can be controlled by the clamps. This ensures that after the workpiece is placed on the support 3, there is a small gap between the dust cover 10 and the workpiece. This facilitates workpiece loading and effectively reduces the rotation angle required for the control ring 20, making operation easier.

[0045] Optionally, the control screw 24 in the limiting groove 23 is slidably installed in the limiting groove 23 and threadedly connected to the positioning seat 25, and the positioning rod 26 is fixed on the top of the positioning seat 25. When performing batch drilling of workpieces, the distance between the drilling position and the edge position of the workpiece is calculated. At this time, the two control screws 24 in the two positioning parts 5 are rotated to control the two positioning seats 25 to move in the two limiting grooves 23, driving the two positioning rods 26 to move to the appropriate position on the support 3. Then, the workpiece to be drilled is placed on the support 3, and the workpiece to be drilled is simultaneously abutted against the two positioning rods 26, so that the positioning of the workpiece to be drilled can be completed quickly, which facilitates the batch drilling operation of the workpiece.

[0046] Optionally, the positioning part 5 further includes a rotating handle 27 hinged to one end of the control screw 24, which is disposed on the support 3 and has a scale groove 28 corresponding to the limiting groove 23. In use, the rotating handle 27 is perpendicular to the control screw 24. The user can control the control screw 24 to rotate by rotating the handle 27. After the control screw 24 is rotated, the angle of the rotating handle 27 relative to the control screw 24 can be adjusted by rotating the handle 27 to prevent the part of the rotating handle 27 from being higher than the upper surface of the support 3, thus affecting the placement of the workpiece on the support 3.

[0047] When the positioning rod 26 in the two positioning parts 5 is being adjusted, the corresponding scale groove 28 can be observed to ensure the accuracy of the adjustment of the positioning rod 26 and the accuracy of the workpiece drilling positioning.

[0048] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
