Description

Technical Field

[0001] The invention relates to the technical field of linear guide rail processing, and in particular to a drilling device for linear guide rail processing with a positioning and correction mechanism. Background Art

[0002] Linear guides are an indispensable key component in modern mechanical equipment. They can provide smooth and precise linear motion for mechanical systems and are widely used in CNC machine tools, robots, automation equipment and other fields. Linear guides are usually composed of guide rails, sliders, bearings and other components. They have the characteristics of high precision, high speed, high acceleration and low friction. In the production process of linear guides, drilling is an important processing link. Linear guides have extremely high requirements for the position accuracy and dimensional accuracy of the holes. Any slight deviation may affect the performance and service life of the guides.

[0003] The patent document with announcement number CN216680352U discloses a drilling device with a positioning mechanism for linear guide rail processing, including an adjusting punching mechanism, a locking and fixing mechanism and a positioning punching mechanism; during the punching process, when the punching needle descends to contact the material to punch, the positioning holes evenly distributed along the inner wall of the top of the positioning plate can limit the needle head of the punching needle to prevent the punching position from shifting and causing processing errors. When responding to different punching requirements and needs, the screws can be removed through the threaded structure composed of the screws and the mounting frame of the positioning plate to separate the positioning plate from the mounting frame, and the positioning plates with different hole spacing requirements can be replaced according to production needs, making the punching process more flexible and adjustable.

[0004] When in use, the above patent document limits the needle tip of the punching needle through the positioning holes evenly distributed on the inner wall of the top of the positioning plate to prevent processing errors caused by the deviation of the punching position. However, in actual use, due to factors such as the size and direction of the drilling force and the material and structure of the linear guide itself, the linear guide may still be offset.

DETAILED DESCRIPTION

[0029] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] See also Figures 1 to 8 As shown, the present invention provides a drilling device for linear guide rail processing with a positioning and correction mechanism, including a workbench 1, screw slides 2 are installed on both sides of the workbench 1, a gantry 3 is provided at the working end of the screw slide 2, a drilling device 4 is movably provided on the gantry 3, an adjusting mechanism for driving the drilling device 4 to move is provided on the gantry 3, a fixing component 5 for clamping the linear guide rail is provided on the workbench 1, and a positioning and correction component 6 for preventing the linear guide rail from deviating during drilling is also provided on the workbench 1.

[0031] The linear guide to be processed is placed on the workbench 1 and firmly clamped with the fixing component 5. At the same time, according to the processing requirements, the gantry 3 is driven to move by starting the screw slide 2, and the gantry 3 drives the drilling device 4 to move. The position of the drilling device 4 can be accurately adjusted by the adjustment mechanism. Before drilling begins, the positioning and correction component 6 starts working to accurately position and correct the linear guide to ensure that it will not deviate during the drilling process.

[0032] See also Figures 4 to 6As shown, the positioning and correction assembly 6 includes a connecting plate 61, a right correction plate 62, a fixed plate 63, a third threaded rod 64, a knob 65 and a left correction plate 66; the connecting plate 61 is arranged on the gantry 3; the right correction plate 62 is movably arranged on the connecting plate 61, and a disc driving component for driving the right correction plate 62 to move is arranged on the connecting plate 61; the fixed plate 63 is arranged on the gantry 3 and is located on one side of the right correction plate 62; the third threaded rod 64 is arranged between the right correction plate 62 and the fixed plate 63, and one end of the third threaded rod 64 extends outward through the fixed plate 63; the knob 65 is arranged at the extended end of the third threaded rod 64; the left correction plate 66 is threadedly arranged on the third threaded rod 64.

[0033] The linear guide to be processed is placed on the workbench 1 and is initially clamped using the fixing assembly 5. The disc driving component is started to drive the right correction plate 62 to move until the right correction plate 62 is tightly fitted with one side of the linear guide. At this time, the knob 65 is rotated to drive the third threaded rod 64 to rotate, and the rotation of the third threaded rod 64 drives the left correction plate 66 to move until the left correction plate 66 is tightly fitted with the other side of the linear guide, thereby clamping both sides of the linear guide to achieve the correction and positioning of the linear guide, avoid the position deviation of the linear guide due to vibration during drilling, and ensure that the position of the linear guide is more accurate during drilling, thereby better meeting the drilling requirements.

[0034] See also Figure 4 and Figure 6 As shown, the bottom of the right correction plate 62 and the bottom of the left correction plate 66 are both provided with limit sliders, and the connecting plate 61 is provided with limit sliding grooves for the limit sliders to move.

[0035] When the right correction plate 62 and the left correction plate 66 move respectively, the limit sliders arranged at the bottom ends of the right correction plate 62 and the left correction plate 66 slide in the limit slide grooves opened on the connecting plate 61, and the right correction plate 62 and the left correction plate 66 are guided by the limit slide grooves, and additional support is provided by the limit sliders, thereby ensuring the stability of the movement of the right correction plate 62 and the left correction plate 66.

[0036] See also Figures 4 to 6As shown, the disc driving component includes a driving box 67, a second motor 68, a rotating disk 69, a fixed column 610, an arc seat 611 and a driving plate 612; the driving box 67 is arranged on the connecting plate 61; the second motor 68 is arranged in the driving box 67; the rotating disk 69 is arranged at the output end of the second motor 68; the fixed column 610 is arranged on the upper end surface of the rotating disk 69; the arc seat 611 is arranged on the rotating disk 69, the fixed column 610 is in the arc seat 611, and the outer wall of the fixed column 610 is in contact with the inner wall of the arc seat 611; the driving plate 612 is arranged at one end of the arc seat 611, and a through groove for the driving plate 612 to move is opened on the driving box 67, and the driving plate 612 is connected to the right correction plate 62.

[0037] When the position of the right correction plate 62 needs to be adjusted, the second motor 68 is started, the rotating disk 69 is driven by the second motor 68 to rotate, and the rotating disk 69 drives the fixed column 610 to start rotating. When the fixed column 610 rotates, it drives the arc seat 611 to move, and the movement of the arc seat 611 drives the driving plate 612 to move, and the driving plate 612 drives the right correction plate 62 to move, thereby realizing lateral adjustment of the right correction plate 62.

[0038] See also Figures 6 to 8 As shown, the fixing assembly 5 includes a fixing seat 51, a first threaded rod 52, a pressure plate 53, a turntable 54 and a limiting rod 55; two fixing seats 51 are provided, and the fixing seats 51 are movably arranged on the workbench 1, and a threaded driving component for driving the fixing seat 51 to move is arranged on the workbench 1; the first threaded rod 52 is arranged on the fixing seat 51; the pressure plate 53 is arranged on the first threaded rod 52; the turntable 54 is threadedly arranged on the first threaded rod 52, and the turntable 54 is rotatably arranged in the pressure plate 53; the limiting rod 55 is arranged on the fixing seat 51 at one side of the first threaded rod 52, and the pressure plate 53 is slidably arranged on the limiting rod 55.

[0039] The linear guide to be processed is placed on the fixed seat 51, and the positions of the two fixed seats 51 are adjusted by the threaded driving component to adapt to linear guides of different lengths. When the fixed seat 51 is moved to a suitable position, the turntable 54 is rotated, and the turntable 54 is threadedly connected to the first threaded rod 52. When the turntable 54 rotates, it will drive the pressure plate 53 to move along the limit rod 55 until the lower end surface of the pressure plate 53 is in tight contact with the surface of the linear guide, thereby effectively ensuring the accuracy and stability of the drilling.

[0040] See also Figure 8 As shown, the lower end surface of the pressing plate 53 and the upper end surface of the fixing seat 51 are both attached with a protective layer, and the protective layer is made of rubber material.

[0041] When the pressure plate 53 and the fixed seat 51 are in contact with the upper and lower end surfaces of the linear guide, a protective layer of rubber material is provided on the pressure plate 53 and the fixed seat 51. The rubber material increases the friction with the linear guide, making it difficult for the linear guide to detach and difficult to cause damage to the surface of the linear guide.

[0042] See also Figure 7 and Figure 8 As shown, a smooth rod 56 is provided on the fixing seat 51 at the other side of the first threaded rod 52 , and a through hole is opened on the pressing plate 53 for the pressing plate 53 to move on the smooth rod 56 .

[0043] When the pressing plate 53 moves, the light rod 56 guides the pressing plate 53 through the through-hole to ensure that the pressing plate 53 does not deviate from the predetermined vertical path during the lifting process. Moreover, since the light rod 56 is located on the other side of the first threaded rod 52, the balance of the pressing plate 53 is maintained during the movement, making the pressing plate 53 more stable and reliable during the movement.

[0044] See also Figure 7 As shown, the threaded driving component includes a second threaded rod 57, a driving disk 58 and a moving block 59; a rectangular groove is opened on the workbench 1, and the second threaded rod 57 is arranged in the rectangular groove, and one end of the second threaded rod 57 passes through the workbench 1 and extends outward; the driving disk 58 is arranged at the extended end of the second threaded rod 57; the moving block 59 is arranged on the second threaded rod 57, and the moving block 59 is connected to the fixed seat 51.

[0045] When the position of the fixed seat 51 needs to be adjusted, the driving disk 58 is rotated to drive the second threaded rod 57 to rotate, and then the second threaded rod 57 drives the moving block 59 to move. Since the moving block 59 is connected to the fixed seat 51, the position of the fixed seat 51 is adjusted by moving the moving block 59, so that it can adapt to linear slide rails of different lengths.

[0046] See also Figure 3 As shown, the adjustment mechanism includes an adjustment threaded rod 41, a first motor 42, a mounting block 43, an extension block 44 and a slide rod 45; the adjustment threaded rod 41 is arranged in the gantry 3; the first motor 42 is arranged on one side of the gantry 3, and the output end of the first motor 42 is connected to the adjustment threaded rod 41; the mounting block 43 is arranged on the adjustment threaded rod 41; the slide rod 45 is arranged in the gantry 3 and is located on both sides of the adjustment threaded rod 41; the extension blocks 44 are arranged on both sides of the mounting block 43, and the extension blocks 44 are slidably arranged on the slide rod 45.

[0047] When the position of the drilling device 4 needs to be precisely adjusted, the first motor 42 is started, the adjusting threaded rod 41 is driven to rotate by the first motor 42, and the rotation of the adjusting threaded rod 41 drives the mounting block 43 to move, and the mounting block 43 drives the drilling device 4 to be adjusted, thereby achieving the effect of precise drilling.

[0048] See also Figure 3 As shown, sliding rods 45 are provided in the gantry 3 and on both sides of the adjusting threaded rod 41 , and extending blocks 44 are provided on both sides of the mounting block 43 , and the extending blocks 44 are slidably provided on the sliding rods 45 .

[0049] When the installation block 43 moves, the extension blocks 44 on both sides thereof slide on the slide bars 45 , so that the installation block 43 is more stable during the movement.

[0050] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention.
