Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to an automotive parts drilling device. Background Technology

[0002] In the field of machining, the drilling of parts requires stringent precision and efficiency. Traditional drilling equipment suffers from problems such as cumbersome positioning and adjustment, and insufficient clamping stability. Manual operation is time-consuming to fix the parts and is prone to displacement due to uneven clamping force, affecting drilling accuracy. To address these pain points, there is an urgent need to develop an automated device that can quickly adapt to parts of different sizes and achieve stable clamping, thereby improving processing efficiency and finished product yield, and meeting the standardized production needs of modern manufacturing.

[0003] Existing technology authorization announcement number CN210702651U discloses a drilling device for automotive parts, including a base. Support pillars are fixedly connected to the four corners of the lower end of the base. A through-groove is formed in the middle of the upper end of the base, and a tensioning device is inserted through the middle of the through-groove. The lower part of the tensioning device passes through the through-groove and is located below the base. Support rods are fixedly connected to the upper left and right sides of the tensioning device, and connecting rods are movably connected to the upper ends of the two sets of support rods via pivots. Clamping devices are symmetrically connected to the ends of the connecting rods away from the support rods. A drilling device is fixedly connected to the rear upper end of the base, and a dust collection box is movably connected to the lower end of the base. This utility model discloses a drilling device for automotive parts by incorporating clamping devices within the device.

[0004] While existing technologies can clamp automotive parts of varying sizes using clamping devices to facilitate drilling, and can further secure the clamping mechanism with tensioning devices, the tightening and adjustment procedures are complex in actual use. This increases the difficulty of operation for workers and also affects processing efficiency. Furthermore, when placing automotive parts, the bottom platform of this device has a panel-like structure that occupies a large proportion of the drillable area. This necessitates manual movement and re-clamping of the part when drilling is required in the center area, further reducing work efficiency. Therefore, we propose an automotive parts drilling device that solves the problems of complex operation procedures and small effective drilling area, reduces the difficulty of operation for workers, improves the ease of use of the device, and ensures efficient processing of automotive parts. Utility Model Content

[0005] The purpose of this utility model is to provide a drilling device for automotive parts, which solves the problems of complex clamping procedures and small effective drilling area of ​​existing automotive parts drilling devices mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a drilling device for automotive parts, comprising a processing platform, a side plate fixedly mounted at one end of the processing platform, and a fixed column fixedly mounted on the top surface of the other end of the processing platform, a support plate fixedly mounted on the side plate near the fixed column, two first sliding grooves horizontally opened inside the support plate, two first sliders slidably mounted inside the first sliding grooves, and a top support rod fixedly mounted on the side of the first slider near the fixed column.

[0007] The pallet is movably equipped with an upper clamping rod and a lower clamping rod at its top and bottom, respectively. Guide rods are symmetrically arranged at both ends of the upper and lower clamping rods near the side plate. The guide rods pass through the side plate and are slidably connected to it. A connecting plate is fixedly installed at the end of the guide rod away from the fixed column. A clamping screw is threaded through the center of the connecting plate. The clamping screw is rotatably connected to the side plate near the side plate through a bearing seat.

[0008] The upper and lower clamping rods are symmetrically installed on both sides of the support plate. A second sliding groove is formed inside each clamping rod, and a second slider is slidably installed inside the second sliding groove. A bidirectional lead screw is threaded through and connected to the lower end of the second slider. Both ends of the bidirectional lead screw are rotatably connected to both ends of the second sliding groove. One end of the bidirectional lead screw passes through the second sliding groove and is fixedly fitted with a rotating block. A rubber protective pad is fixedly attached to the side of the second slider near the side plate. A rotating handle is fixedly installed at the end of the clamping screw away from the side plate. One end of the first sliding groove passes through the support plate, and a limit block is embedded at one end of the first sliding groove via screws. A rubber block is fixedly attached to the end of the top support rod away from the first slider.

[0009] The fixed column has a through groove inside, and a third sliding groove is formed on the inner wall of the through groove. A third slider is slidably installed inside the third sliding groove. A lead screw is vertically threaded through the center of the third slider and connected to it.

The PLC controller is electrically connected to the servo motor, the hydraulic telescopic rod, and the rotary motor.

[0011] This utility model discloses a drilling device for automotive parts. Through a first groove on one side of the support plate, combined with a first slider, it allows operators to flexibly adjust the spacing of the top support rods according to the different sizes of automotive parts. The design of the top support rods not only provides support during clamping of the automotive parts, but also, due to their point-contact method, significantly reduces the contact area between the top support rods and the automotive parts, avoiding interference with drilling operations in the central area of ​​the automotive parts. With the arrangement of the upper clamping rod, lower clamping rod, connecting plate, and clamping screw, operators only need to rotate a single clamping screw to drive the upper and lower clamping rods to achieve the clamping effect on the automotive parts. The operation is simple and convenient, effectively improving the processing efficiency of automotive parts. Furthermore, the cooperation of the second groove and the second slider allows operators to easily adjust the clamping points according to the different sizes of automotive parts, making it flexible, convenient, and highly adaptable.

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] Please see Figures 1-4 This utility model provides a technical solution: a drilling device for automotive parts, including a processing platform 1, a side plate 2 fixedly installed at one end of the processing platform 1, and a fixed post 3 fixedly installed on the top surface of the other end of the processing platform 1. A support plate 4 is fixedly installed on the side of the side plate 2 near the fixed post 3. Two first sliding grooves 5 are horizontally opened inside the support plate 4. Two first sliders 6 are slidably installed inside the first sliding grooves 5. A top support rod 7 is fixedly installed on the side of the first slider 6 near the fixed post 3. One end of the first sliding groove 5 passes through the support plate 4. A limit block 18 is embedded in the first sliding groove 5 by screws. A rubber block 19 is fixedly pasted on the end of the top support rod 7 away from the first slider 6.

[0020] Through the sliding engagement of the first slider 6 and the first groove 5, the operator can flexibly adjust the spacing between the four top support rods 7 to accommodate the size of the parts. During clamping, the rubber blocks 19 at the ends of the top support rods 7 make point contact with the surface of the automotive parts, which not only provides effective support but also expands the area of ​​the automotive parts that can be drilled, thus improving the practicality of the device.

[0021] The top and bottom of the pallet 4 are respectively movably installed with an upper clamping rod 8 and a lower clamping rod 9. Guide rods 10 are symmetrically arranged at both ends of the upper clamping rod 8 and the lower clamping rod 9 near the side plate 2. The guide rods 10 pass through the side plate 2 and are slidably connected to the side plate 2. A connecting plate 11 is fixedly installed at the end of the guide rod 10 away from the fixed column 3. A clamping screw 12 is threaded through the center of the connecting plate 11. The end of the clamping screw 12 near the side plate 2 is rotatably connected to the side plate 2 through a bearing seat 13. The upper clamping rod 8 and the lower clamping rod 9 are symmetrically installed on both sides of the pallet 4. A second sliding groove 14 is opened inside the upper clamping rod 8 and the lower clamping rod 9. A second slider 15 is slidably installed inside the second sliding groove 14. A rubber protective pad 16 is fixedly pasted on the side of the second slider 15 near the side plate 2. A rotating handle 17 is fixedly installed at the end of the clamping screw 12 away from the side plate 2.

[0022] By moving the second slider 15 to the four corners of the accessory and then rotating the handle 17 counterclockwise, the rotation of the clamping screw 12 causes the connecting plate 11 to move in the opposite direction to the side plate 2, which in turn drives the upper clamping rod 8 and the lower clamping rod 9 to move towards the side plate 2, thus clamping and fixing the accessory between the top support rod 7 and the upper clamping rod 8 and the lower clamping rod 9. The sliding action of the second slider 15 and the second slide groove 14 allows the operator to flexibly adjust the clamping points according to different sized automotive accessories, making it more convenient to use.

[0023] The fixed column 3 has a through groove 20 inside, and a third sliding groove 21 is formed on the inner wall of the through groove 20. A third slider 22 is slidably installed inside the third sliding groove 21. A lead screw 23 is threaded through the center of the third slider 22 and connected to it. A servo motor 24 is fixedly installed at the top of the fixed column 3. The output end of the servo motor 24 is fixedly connected to the top of the lead screw 23 through a coupling. The bottom end of the lead screw 23 is rotatably installed on the bottom surface of the through groove 20. A hydraulic telescopic rod 25 is fixedly installed on the side of the third slider 22 near the side plate 2. A mounting plate 26 is fixedly installed at one end of the hydraulic telescopic rod 25. A rotary motor 27 is fixedly installed on one side of the mounting plate 26. A drilling bit 28 is fixedly connected to the output end of the rotary motor 27. A shelf 29 is fixedly installed at the angle between the top surface of the processing platform 1 and the side plate 2. A PLC controller 30 is fixedly installed on one side of the processing platform 1. The PLC controller 30 is electrically connected to the servo motor 24, the hydraulic telescopic rod 25, and the rotary motor 27.

[0024] The servo motor 24 drives the lead screw 23 to rotate, which in turn drives the third slider 22 to move up and down to the appropriate drilling height. Then, the hydraulic telescopic rod 25 and the rotary motor 27 are activated. The rotary motor 27 drives the drilling bit 28 to rotate at high speed. The hydraulic telescopic rod 25 drives the drilling bit 28 to move towards the surface of the part, thus achieving the drilling effect of the part.

[0025] Working principle: First, according to the required size of the part to be drilled, pull the top support rod 7. The distance between the four top support rods 7 is adjusted by the sliding cooperation between the first slider 6 and the first groove 5 to adapt to the size of the part. Then, place the side of the part onto the end face of the top support rod 7. Move the second slider 15 to the four corner areas of the part. Then, rotate the handle 17 counterclockwise. The rotation of the clamping screw 12 causes the connecting plate 11 to move in the opposite direction to the side plate 2, which in turn drives the upper clamping rod 8 and the lower clamping rod 9 to move in the direction of the side plate 2, so that the part is clamped and fixed between the top support rod 7 and the upper clamping rod 8 and the lower clamping rod 9. After that, the servo motor 24 is started by the PLC controller 30. The servo motor 24 drives the lead screw 23 to rotate, which in turn drives the third slider 22 to move up and down to the appropriate drilling height. Then, the hydraulic telescopic rod 25 and the rotary motor 27 are activated. The rotary motor 27 drives the drilling bit 28 to rotate at high speed. The hydraulic telescopic rod 25 drives the drilling bit 28 to move towards the surface of the part, realizing the drilling effect of the part.
