Description

Technical Field

[0001] This utility model relates to the field of CNC machining technology, and in particular to a CNC machining positioning system for drill joint threads. Background Technology

[0002] Thread CNC machining uses a CNC system to control the movement of the machine tool. The operator pre-inputs thread machining parameters, such as pitch (the axial distance between corresponding points on adjacent thread teeth), thread angle (the angle between the thread flank and the perpendicular line to the thread axis), and thread diameter, into the controller, which then performs automated machining based on the parameters.

[0003] Existing clamping components used in machining positioning systems have shortcomings in clamping reliability: many drill bit clamping mechanisms cannot guarantee uniform clamping force when clamping drill bit joints. For example, mechanisms using single-point clamping may generate high pressure only at localized locations on the drill bit joint during clamping, while the pressure is lower in other areas. This can lead to deformation of the drill bit joint during machining, especially when machining long drill bit joints. Uneven clamping force can cause bending deformation of the drill bit joint, thereby affecting the machining accuracy of the threads and causing the thread shape and dimensions to fail to meet design requirements.

[0004] To address the shortcomings of the aforementioned technologies, we propose a CNC machining and positioning system for drill joint threads. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a CNC machining positioning system for drill joint threads.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A CNC machining and positioning system for drill bit joint threads includes a machining table, on which a plane adjustment mechanism and a drill bit clamping mechanism are provided. The drill bit clamping mechanism includes a fixed cylinder and a hydraulic pump. Three sliding grooves are formed through the side wall of the fixed cylinder. A hydraulic cavity is fixedly installed inside the sliding groove. A hydraulic push block is slidably installed inside the hydraulic cavity. A pressure equalizing ring tube is sleeved on the outside of the fixed cylinder. An arc pipe is installed between the pressure equalizing ring tube and the hydraulic cavity. A hydraulic oil pipe is installed between the hydraulic pump and the pressure equalizing ring tube. A clamping plate is fixedly installed on the inner side of the hydraulic push block.

[0008] Furthermore, anti-slip textures are evenly distributed on the inner side of the clamping plate.

[0009] Furthermore, the planar adjustment mechanism includes a sliding plate and a disc. The bottom of the sliding plate is slidably connected to the upper side of the processing table, and the bottom of the disc is slidably connected to the sliding plate. A synchronous electric telescopic rod is symmetrically fixedly connected between the side of the sliding plate and the processing table. A slot is opened on the upper side of the sliding plate, and a locking block is fixedly installed on the bottom of the disc. The locking block is slidably engaged with the slot, and a built-in electric telescopic rod is fixedly installed between the locking block and the inner wall of the slot.

[0010] Furthermore, both the fixed cylinder and the hydraulic pump are fixedly mounted on the upper side of the disc.

[0011] Furthermore, a frame is fixedly installed on the upper side of the processing table, and a controller is fixedly installed on the outer wall of the frame.

[0012] Furthermore, a sliding column slides through the upper side of the frame, and an electric lifting rod is symmetrically and fixedly connected between the side of the sliding column and the upper side of the frame. A top plate is fixedly installed at the lower end of the sliding column, and a high-speed motor is fixedly installed on the lower side of the top plate. A cutting tool is fixedly installed on the output end of the high-speed motor.

[0013] Furthermore, a number of side strips are fixedly provided on the outer wall of the sliding column, and the side strips are usually provided along the outer side of the sliding column.

[0014] Furthermore, a stabilizing sleeve is fixedly installed at the bottom of the frame, and the sliding column slides through the stabilizing sleeve.

[0015] Compared with related technologies, the CNC machining positioning system for drill joint threads proposed in this utility model has the following advantages:

[0016] In this utility model, a CNC machining positioning system for drill bit joint threads is described. Through a drill bit clamping mechanism, a hydraulic system provides a stable clamping force, making the clamping force more stable. When clamping the drill bit, the hydraulic pump is activated to push hydraulic oil through hydraulic oil pipes, pressure equalizing ring pipes, and arc pipes to the hydraulic chambers. These three synchronously arranged hydraulic chambers push the hydraulic push blocks on their inner sides to slide towards the inside of the fixed cylinder, thereby causing the inner clamping plate to clamp the outer side of the drill bit. This ensures that the outer side of the drill bit is evenly subjected to clamping forces in three directions, making the clamping more stable. Simultaneously, anti-slip textures are evenly distributed on the clamping plate, increasing the internal clamping friction and preventing slippage or misalignment of the drill bit during machining. This enhances the stability of the entire drill bit clamping mechanism and helps ensure the machining accuracy of the drill bit. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Reference Figure 1-6 A CNC machining and positioning system for drill bit joint threads includes a machining table 1, on which a plane adjustment mechanism 2 and a drill bit clamping mechanism 3 are provided. The drill bit clamping mechanism 3 includes a fixed cylinder 31 and a hydraulic pump 38. Three sliding grooves 32 are provided through the side wall of the fixed cylinder 31. A hydraulic cavity 33 is fixedly installed inside the sliding groove 32. A hydraulic push block 34 is slidably installed inside the hydraulic cavity 33. A pressure equalizing ring tube 36 is sleeved on the outside of the fixed cylinder 31. An arc pipe 37 is installed between the pressure equalizing ring tube 36 and the hydraulic cavity 33. A hydraulic oil pipe 39 is installed between the hydraulic pump 38 and the pressure equalizing ring tube 36. A clamping plate 35 is fixedly installed on the inner side of the hydraulic push block 34.

[0026] In this method, anti-slip textures are evenly distributed on the inner side of the clamping plate 35.

[0027] By setting the anti-slip texture as described above, the clamping plate 35 has better clamping and anti-slip performance, preventing the drill bit from slipping or deviating during processing.

[0028] In this method, the planar adjustment mechanism 2 includes a slide plate 21 and a disc 23. The bottom of the slide plate 21 is slidably connected to the upper side of the processing table 1, and the bottom of the disc 23 is slidably connected to the slide plate 21. A synchronous electric telescopic rod 22 is symmetrically fixedly connected between the side of the slide plate 21 and the processing table 1. A slot 24 is opened on the upper side of the slide plate 21. A locking block 25 is fixedly installed on the bottom of the disc 23. The locking block 25 is slidably engaged with the slot 24. An internal electric telescopic rod 26 is fixedly installed between the locking block 25 and the inner wall of the slot 24.

[0029] With the above-mentioned configuration, when the synchronous electric telescopic rod 22 is started, it can drive the slide plate 21 to slide left and right on the upper side of the processing table 1, thereby changing the left and right position of the drill bit fixedly held in the drill bit clamping mechanism 3. When the built-in electric telescopic rod 26 is started, it can drive the front and back position of the drill bit fixedly held in the drill bit clamping mechanism 3. Thus, through the cooperation of the synchronous electric telescopic rod 22 and the built-in electric telescopic rod 26, the position adjustment of the drill bit on the plane can be completed.

[0030] In this method, a sliding column 6 slides through the upper side of the frame 4, and an electric lifting rod 8 is symmetrically and fixedly connected between the side of the sliding column 6 and the upper side of the frame 4. A top plate 10 is fixedly installed at the lower end of the sliding column 6, and a high-speed motor 11 is fixedly installed on the lower side of the top plate 10. A cutter 12 is fixedly installed on the output end of the high-speed motor 11.

[0031] With the above-mentioned configuration, the sliding column 6 can slide vertically on the frame 4 driven by the electric lifting rod 8, thereby driving the high-speed motor 11 on the lower side and the up-and-down movement of the output end of the high-speed motor 11. In conjunction with the above-mentioned planar adjustment mechanism, the relative spatial position of the tool 12 and the drill fixed in the drill clamping mechanism 3 can be changed, realizing the three-dimensional cutting function of the tool 12, and processing can be performed at different positions of the drill.

[0032] In this method, several side strips 7 are fixedly installed on the outer wall of the sliding column 6. The side strips 7 are usually installed along the outer side of the sliding column 6. A stabilizing sleeve 9 is fixedly installed at the bottom of the frame 4. The sliding column 6 slides through the stabilizing sleeve 9.

[0033] By setting the side strip 7 as described above, the rotational freedom of the slide column 6 is restricted when it moves up and down, making the sliding of the slide column 6 more stable. In addition, the setting of the stabilizing sleeve 9 further improves the sliding stability of the slide column 6, so that the tool 12 will not shake when adjusting the up and down position.

[0034] In this configuration, both the fixed cylinder 31 and the hydraulic pump 38 are fixedly mounted on the upper side of the disc 23.

[0035] With the above configuration, the disc 23 provides fixed support for the fixed cylinder 31 and the hydraulic pump 38.

[0036] In this method, a frame 4 is fixedly installed on the upper side of the processing table 1, and a controller 5 is fixedly installed on the outer wall of the frame 4.

[0037] Through the above-described configuration, controller 5 is used to control the coordinated operation of various electrical components in this invention for automated processing.

[0038] The working principle of the CNC machining positioning system for drill joint threads provided by this utility model is as follows:

[0039] In use, the drill bit to be processed is placed in the fixed cylinder 31. Then, the hydraulic pump 38 is started, pushing the hydraulic oil inside the cylinder into the hydraulic oil pipe 39. The oil is then simultaneously pushed into the three hydraulic chambers 33 through the hydraulic oil pipe 39, the pressure equalizing ring pipe 36, and the arc pipe 37. This causes the hydraulic chambers 33 to push the hydraulic push blocks 34 inside to slide into the fixed cylinder 31. The clamping plates 35 installed inside the hydraulic push blocks 34 then abut against and clamp the drill bit against the outer wall, thus fixing the drill bit. The control parameters for drill bit processing are then input into the controller. In step 5, the controller 5 controls the high-speed motor 11 to start and drive the tool 12 to rotate at high speed for cutting. Subsequently, according to the processing parameters, the controller controls the synchronous electric telescopic rod 22, the built-in electric telescopic rod 26 and the electric lifting rod 8 to work together to change the relative position between the tool 12 and the drill bit. After the processing of the drill bit is completed, the hydraulic pump 38 starts to return oil, which causes the hydraulic push block 34 inside the hydraulic chamber 33 to retract, thereby causing the clamping plate 35 to release the drill bit held inside. At this time, the processed drill bit can be taken out from the inside of the fixed cylinder 31.

[0040] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
