Description

Technical Field

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

[0002] In the agricultural sector, PVC pipe fittings are widely used in key areas such as irrigation systems and drainage projects due to their significant advantages, including corrosion resistance, low cost, and ease of installation. When drilling PVC pipe fittings, it is necessary to follow conventional drilling methods while also incorporating more efficient technologies to meet the specific needs of agricultural production.

[0003] The prior art discloses a pipe drilling machine that can drill holes in pipes, reducing the labor intensity of workers. However, the machine only has one station. After processing a pipe, drilling needs to be paused, the pipe needs to be reloaded, and the pipe needs to be positioned and clamped. Drilling can only continue after the pipe is fixed. This process wastes a lot of time, the continuity of the entire processing is not enough, and the production efficiency is reduced. Utility Model Content

[0004] The purpose of this utility model is to overcome the problem of insufficient continuity in the processing of pipe drilling machines in the prior art, and to provide a pipe drilling machine that does not require stopping the machine when processing new pipes, thereby improving continuity and production efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A pipe drilling machine is provided, comprising a platform, a gantry mechanism, a transfer mechanism, a drilling mechanism, and at least two clamping mechanisms disposed on the platform. The clamping mechanisms are used to clamp pipes and maintain parallelism between all pipes. The gantry mechanism is slidably connected to the platform and the sliding direction is along a first direction. The transfer mechanism is slidably connected to the gantry mechanism and the sliding direction is along a second direction. The first direction or the second direction is parallel to the pipe axis, and the first direction is perpendicular to the second direction. The drilling mechanism is slidably connected to the transfer mechanism and the sliding direction is along a third direction, and the third direction is perpendicular to the pipe axis.

[0007] This utility model discloses a pipe drilling machine. The platform is equipped with at least two clamping mechanisms, and the number of clamping mechanisms corresponds to the number of workstations. Operators can install pipes onto the clamping mechanisms to complete the positioning and fixing of the pipes. A gantry mechanism slides relative to the platform along a first direction, a transfer mechanism moves relative to the gantry mechanism along a second direction, and a drilling mechanism moves relative to the transfer mechanism along a third direction. Therefore, the drilling mechanism can achieve three-axis motion. First, the drilling mechanism moves to the first workstation along a direction perpendicular to the pipe axis. Then, the drilling mechanism feeds along a direction perpendicular to the pipe axis, drilling into the outer wall of the pipe. The machine then moves the drilling mechanism along the pipe axis to continue drilling. After processing the pipe at one station, the drilling mechanism is moved to the next station to repeat the above operation for the next pipe. During the processing, the operator can remove the previously processed pipe and reinstall it on the clamping mechanism corresponding to the station. The time for installing the pipe is much less than the time for processing a single pipe. Therefore, by repeating the above operation, the machine can be processed without stopping after processing one pipe, enabling continuous processing of pipes with better continuity and higher efficiency.

[0008] Furthermore, the top surface of the platform is parallel to the horizontal plane, the gantry mechanism is located above the platform, and the third direction is vertical. With the platform parallel to the horizontal plane and the drilling mechanism drilling vertically, the platform provides upward support to the pipe, improving drilling stability.

[0009] Furthermore, a first guide rail and a second guide rail are respectively provided on both sides of the platform along a first direction. The gantry mechanism includes a first support member, a second support member, a first driving member disposed on the first support member, a second driving member disposed on the second support member, and a crossbeam for connecting the first support member and the second support member. The first support member is slidably connected to the first guide rail, and the second support member is slidably connected to the second guide rail. The first driving member drives the first support member to slide along the first guide rail, and the second driving member drives the second support member to slide along the second guide rail. Simultaneous driving from both sides improves stability.

[0010] Furthermore, a first rack and a second rack are respectively arranged on both sides of the platform along a first direction. A first gear is provided at the output end of the first driving member, and a second gear is provided at the output end of the second driving member. The first gear meshes with the first rack, and the second gear meshes with the second rack. Through the meshing of the first gear with the first rack and the second gear with the second rack, the gantry mechanism is driven to slide relative to the platform. The gear and rack transmission has strong load-bearing capacity and good stability.

[0011] Furthermore, the gantry mechanism is provided with a third guide rail and a third rack along the second direction. The transfer mechanism includes a support plate connected to the gantry mechanism, a third driving member connected to the support plate, a driving assembly connected to the support plate, and a connecting plate connected to the output end of the driving assembly. The output end of the third driving member is connected to a third gear, which meshes with the third rack. The support plate is slidably connected to the third guide rail, and the drilling mechanism is connected to the connecting plate. The third driving member drives the third gear to rotate, and the cooperation between the third gear and the third rack enables the entire transfer mechanism to move in the second direction. The third guide rail improves sliding stability.

[0012] Furthermore, the drive assembly includes a fourth drive member connected to the support plate, a lead screw connected to the output end of the fourth drive member, and a slide table threadedly connected to the lead screw. The support plate is provided with a fourth guide rail along a third direction. The connecting plate, the slide table, and the fourth guide rail are connected. The drilling mechanism is connected to the connecting plate. The fourth drive member drives the lead screw to rotate, and the fourth guide rail restricts the rotation of the slide table. The slide table moves linearly along a third direction. The use of the lead screw and slide table in cooperation results in high transmission accuracy and improves the precision of drilling.

[0013] Furthermore, the drilling mechanism includes a drilling drive connected to the connecting plate and a cutting tool connected to the output end of the drilling drive. The drilling drive provides power for the drilling operation, driving the cutting tool to rotate at high speed to cut and drill holes in the pipe.

[0014] Furthermore, the clamping mechanism includes a base disposed on the top of the platform, a bearing disposed on the top of the base, a rotating shaft rotatably connected to the bearing, a rotation drive connected to one end of the rotating shaft, a pipe clamping member connected to the other end of the rotating shaft, and a top pipe member disposed on the top of the base. The axes of the rotating shaft, the pipe clamping member, and the top pipe member are all collinear with the axis of the pipe. The pipe clamping member clamps one end of the pipe, providing circumferential fixing force to the pipe, while the top pipe member presses against the other end of the pipe, applying axial fixing force to the pipe. This improves the fixing effect of the pipe, ensures stability during drilling, and thus ensures drilling quality.

[0015] Furthermore, the rotation drive component is a handwheel or a motor.

[0016] Furthermore, a drainage channel is provided on the top surface of the platform, and several drainage holes are provided within the drainage channel. A drainage pipe is also installed inside the platform, with one end of the drainage pipe connected to the drainage holes. Debris and coolant generated during drilling can flow through the drainage channel into the drainage pipe inside the platform for unified collection and discharge, keeping the working area clean and preventing any impact on drilling quality and equipment operation.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The device is equipped with multiple workstations, and the drilling mechanism can achieve three-axis movement. During the processing, the operator can remove the previously processed pipe fitting and reinstall the pipe fitting on the clamping mechanism corresponding to the workstation. The above operation can be repeated. After processing one pipe fitting, the machine can be processed without stopping the machine, which can realize continuous processing of pipe fittings, with better processing continuity and higher processing efficiency.

[0019] 2. The first and second support components are slidably connected to both sides of the platform and driven by gears and racks, resulting in strong load-bearing capacity and good stability;

[0020] 3. The drive assembly utilizes the cooperation of a lead screw and a slide table, resulting in high transmission accuracy and improved drilling precision.

[0021] 4. During the drilling process, debris and coolant generated can flow into the platform's internal drainage pipes through the drainage channel for unified collection and discharge, keeping the work area clean and avoiding affecting drilling quality and equipment operation.

[0035] Example 1

[0036] A pipe drilling machine, such as Figure 1As shown, the system includes a platform 100, a gantry mechanism 200 located above the platform 100, a transfer mechanism 300, a drilling mechanism 400, and two clamping mechanisms 500 disposed on the platform 100. The top surface of the platform 100 is parallel to the horizontal plane. The clamping mechanisms 500 are used to clamp the pipe fittings and maintain parallelism between all the pipe fittings. The gantry mechanism 200 is slidably connected to the platform 100 with the sliding direction along a first direction. The transfer mechanism 300 is slidably connected to the gantry mechanism 200 with the sliding direction along a second direction. The first or second direction is parallel to the pipe fitting axis, and the first direction is perpendicular to the second direction. The drilling mechanism 400 is slidably connected to the transfer mechanism 300 with the sliding direction along a third direction, which is vertical. Figure 3 As shown, the top surface of the platform 100 is evenly provided with sewage discharge channels 150 along the first and second directions, and four sewage discharge holes 151 are provided in the sewage discharge channels 150, such as... Figure 4 As shown, the platform 100 is also equipped with a sewage pipe 160. The sewage pipe 160 includes a branch pipe 161 connected to the sewage hole 151 and a main pipe 162 connected to all the branch pipes 161. The branch pipe 161 is a flexible hose.

[0037] The working principle of this embodiment is as follows:

[0038] This utility model discloses a pipe drilling machine. A platform 100 is equipped with two clamping mechanisms 500, corresponding to two processing stations. Before starting the machine, the operator can install the pipe fitting onto the clamping mechanism 500 to complete the positioning and fixing of the pipe fitting. The gantry mechanism 200 slides relative to the platform 100 along a first direction, the transfer mechanism 300 moves relative to the gantry mechanism 200 along a second direction, and the drilling mechanism 400 moves relative to the transfer mechanism 300 along a third direction. Therefore, the drilling mechanism 400 can achieve three-axis motion. The drilling mechanism 400 moves along the second direction... At the first workstation, the drilling mechanism 400 feeds along the third direction to drill holes in the outer wall of the pipe. The operator can manually or automatically adjust the pipe to rotate circumferentially and drill holes in the pipe in the circumferential direction. After drilling one circle of holes, the gantry mechanism 200 starts and drives the drilling mechanism 400 to feed along the first direction. The above operation is repeated to continue drilling. After processing the pipe at one workstation, the drilling mechanism 400 is driven to the next workstation to repeat the above operation to process the next pipe. The operator unloads the processed pipe and installs the pipe to be processed at the workstation.

[0039] The beneficial effects of this embodiment are as follows:

[0040] The device has multiple workstations. With the transfer mechanism 300 feeding in the second direction, the operator can unload the previously processed pipe fitting and reinstall it on the clamping mechanism 500 corresponding to the workstation during the entire processing. The above operation can be repeated. After processing one pipe fitting, the machine can be processed without stopping the machine, which can realize continuous processing of pipe fittings. The processing process is more continuous and the processing efficiency is higher. The platform 100 is parallel to the horizontal plane, and the drilling mechanism 400 drills in the vertical direction. The platform 100 provides upward support for the pipe fitting, which improves the stability of drilling. The debris and coolant generated during the drilling process can flow into the sewage pipe inside the platform through the sewage channel, be collected and discharged, keep the working area clean, and avoid affecting the drilling quality and equipment operation.

[0041] Furthermore, the number of clamping mechanisms 500 can be set to three, four, or more as needed.

The first support member 210 is slidably connected to the first guide rail 110, and the second support member 220 is slidably connected to the second guide rail 120. The output end of the first drive member 230 is provided with a first gear 231, and the output end of the second drive member 240 is provided with a second gear 241.

In this embodiment, the third drive 320, the fourth drive 340, and the drilling drive 410 are all motors.

[0049] The working principle of this embodiment is as follows:

[0050] The third drive unit 320 drives the third gear 321 to rotate. The third gear 321 cooperates with the third rack 252 to enable the entire transfer mechanism 300 to move in the second direction. The third guide rail 251 improves the sliding stability. The fourth drive unit 340 drives the lead screw 350 to rotate. The fourth guide rail 311 restricts the rotation of the slide table 360.
