Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of vertical drilling machines, and more specifically, to a vertical drilling machine for a double-hole spring seat. Background Technology

[0002] In the field of machining, vertical drilling machines are commonly used for machining holes in various parts. As a key mechanical component, the drilling accuracy of double-hole spring seats has a significant impact on the stability of the equipment. Traditional vertical drilling machines face numerous problems when machining double-hole spring seats, which urgently need to be addressed.

[0003] Existing vertical drilling machines are mostly designed for versatility, making it difficult to efficiently machine the special structure of double-hole spring seats. Different specifications and models of double-hole spring seats have varying hole diameters, hole spacings, and overall dimensions, necessitating frequent changes or adjustments to tooling fixtures during machining. For example, to meet the positioning and clamping requirements of different spring seats, companies need to equip themselves with various specialized drilling jigs and positioning blocks, which not only increases the design, manufacturing, and storage costs of tooling but also leads to long changeover times, significantly impacting machining efficiency.

[0004] Frequent tooling changes can lead to unstable machining accuracy. Because different tooling fixtures have different positioning references, repeated clamping can easily generate cumulative errors, causing deviations in the spacing between double holes or excessive perpendicularity of the axis, increasing the defect rate and driving up inspection and rework costs. With the increasing demand for flexible production, traditional machining methods are no longer sufficient to meet the economic requirements of multi-variety, small-batch production. Therefore, developing a new type of vertical drilling machine that can specifically machine double-hole spring seats and reduce reliance on tooling has become an urgent need in the machining industry. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a vertical drilling machine for double-hole spring seats, which solves the technical problem in the prior art where double-hole spring seats of different specifications and models have different hole diameters, hole spacings and external dimensions, which requires frequent replacement or adjustment of tooling fixtures during processing, resulting in high costs and low efficiency.

[0006] According to one aspect, at least one embodiment of this disclosure provides a vertical drilling machine for a double-hole spring seat, comprising:

[0007] The frame, the portal frame, and the drilling motor are provided. The portal frame is fixed to the frame, and the drilling motor is connected to the portal frame via a vertical linear drive.

[0008] A central frame and a positioning and clamping assembly, wherein the central frame is fixed to the surface of the frame body and the positioning and clamping assembly is disposed on the central frame;

[0009] A waste collection and discharge assembly is disposed within the frame.

[0010] The positioning and clamping assembly includes a pair of support frames, both of which are disposed inside the central frame. A pair of transmission grooves are provided on both sides of each support frame, and the support frame is slidably connected in the pair of opposing transmission grooves. A mounting plate is provided on the side surface of the support frame.

[0011] As a further technical solution, internal threaded sleeves are rotatably fitted on both sides of the central frame, and studs are fixed on the side end face of the support frame. One end of the stud is connected to the internal threaded sleeve through a threaded engagement.

[0012] As a further technical solution, a pair of movable rods are movably connected to the inner side surface of the central frame. Positioning frames are fixedly connected to both ends of the movable rods. The top of the positioning frames is located at the upper end of the central frame. The movable rods and the positioning frames are relatively parallel to the support frame.

[0013] As a further technical solution, a spring is fitted onto the movable rod, the spring is located inside the central frame, an elongated hole is provided on the surface of the positioning frame, and a fastening bolt is connected to the upper end face of the central frame by a threaded connection.

[0014] As a further technical solution, the fastening bolt is movably fitted inside the elongated hole, and a crank is fixedly connected to the upper end of the fastening bolt, the upper end of the fastening bolt having a polygonal structure.

[0015] As a further technical solution, the waste collection and discharge component includes a cleaning port, which is opened on the surface of the frame. A collection cover is provided at the bottom of the frame, and a discharge pipe is provided on one side of the collection cover.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:

[0019] In this disclosure, the positioning and clamping assembly solves the problem of frequent tooling changes during the machining of double-hole spring seats of different specifications through the synergistic action of the support frame, the internal threaded sleeve, and the positioning frame. Rotating the internal threaded sleeve allows the support frame to slide along the transmission groove via a stud, flexibly adjusting the spacing to accommodate workpieces of different sizes without the need to change fixtures. The positioning frame, in conjunction with the spring and fastening bolts, can quickly fix the workpiece and maintain stable clamping, avoiding cumulative errors from multiple clamping operations and ensuring drilling accuracy. This design reduces tooling costs and changeover time, improves processing efficiency and flexibility, and meets the needs of multi-variety, small-batch production. Attached Figure Description

[0032] like Figures 1-4 As shown, it illustrates a vertical drilling machine for a double-hole spring 4-8 seat according to an embodiment of the present disclosure, comprising:

[0033] The frame 1, the portal frame 2, and the drilling motor 3 are provided. The portal frame 2 is fixed on the frame 1, and the drilling motor 3 is connected to the portal frame 2 via a vertical linear drive.

[0034] The central frame 8 and the positioning and clamping assembly 4 are provided on the central frame 8.

[0035] Waste collection and discharge component 5 is disposed in the frame 1;

[0036] The positioning and clamping assembly 4 includes a pair of support frames 4-1, both of which are disposed inside the central frame 8. Each support frame 4-1 has a pair of transmission grooves 4-2 on both sides, and the support frame 4-1 is slidably connected within the pair of opposing transmission grooves 4-2. A mounting plate 4-3 is provided on the side surface of each support frame 4-1. Internally threaded sleeves 4-4 are rotatably fitted onto both sides of the central frame 8. A stud 4-5 is fixed to the side end face of each support frame 4-1, with one end of the stud 4-5 threadedly connected to the internally threaded sleeve 4-4. A pair of movable rods 4-6 are movably fitted onto the side surface of the central frame 8. Positioning brackets 4-7 are fixedly connected to both ends of 4-6. The top of the positioning brackets 4-7 is located on the upper end of the central frame 8. The movable rod 4-6 and the positioning brackets 4-7 are parallel to the support frame 4-1. A spring 4-8 is fitted onto the movable rod 4-6. The spring 4-8 is located inside the central frame 8. An elongated hole 4-9 is opened on the surface of the positioning bracket 4-7. A fastening bolt 4-10 is threadedly connected to the upper end of the central frame 8. The fastening bolt 4-10 is movably fitted into the elongated hole 4-9. A crank handle 4-11 is fixedly connected to the upper end of the fastening bolt 4-10. The upper end of the fastening bolt 4-10 has a polygonal structure.

[0037] In some examples, to achieve rapid workpiece positioning and fixation, a positioning and clamping assembly 4 is designed. This assembly includes a pair of support frames 4-1 symmetrically arranged inside the central frame 8. The transmission grooves 4-2 on both sides provide horizontal sliding guide tracks for the support frames 4-1, ensuring smooth movement of the support frames 4-1 within the central frame 8. The mounting plates 4-3 on the side surfaces of the support frames 4-1 have a stepped structure, which fits against the positioning reference surface of the workpiece to form a positioning support.

[0038] The internally threaded sleeves 4-4, which are rotated on both sides of the central frame 8, are connected to the frame via bearings and can rotate freely around their axis. The threads on their inner walls mate with the studs 4-5 on the side end face of the support frame 4-1. When the operator rotates the internally threaded sleeves 4-4, the studs 4-5 move along the thread axis, causing the support frame 4-1 to slide synchronously within the transmission groove 4-2, thus achieving fine-tuning of the workpiece's lateral position. The movable rods 4-6 are horizontally inserted into both sides of the central frame 8, with both ends fixedly connected to the positioning frames 4-7. The top of the positioning frame 4-7 extends to the upper end of the central frame 8, and its elongated holes 4-9 correspond to the fastening bolts 4-10 on the upper end face of the frame. The lower ends of the bolts pass through the elongated holes 4-9 and are threaded into the central frame 8. The crank handle 4-11 at the upper end facilitates manual operation. The positioning frame 4-7 adjusts its position according to the workpiece's specifications and dimensions, and can be fixed in place with bolts to ensure consistent workpiece placement each time.

[0039] The spring 4-8, mounted on the movable rod 4-6, is located inside the central frame 8, with its two ends abutting against the inner wall of the frame and the positioning frame 4-7 respectively, providing elastic preload to keep the positioning frame 4-7 parallel to the support frame 4-1. When it is necessary to fix the workpiece, firstly, the fastening bolt 4-10 is rotated by the crank handle 4-11, and the position of the positioning frame 4-7 is adjusted using the sliding space of the elongated hole 4-9; then, the internal threaded sleeve 4-4 is rotated to push the support frame 4-1 and move the workpiece until the workpiece is clamped by the mounting plate 4-3 and the positioning frame 4-7. The threaded drive between the stud 4-5 and the internal threaded sleeve 4-4 enables adaptive clamping of workpieces of different sizes, and is compatible with the machining of various specifications of double-hole spring 4-8 seats.

[0040] This component, through the cooperation of the mounting plate 4-3 and the positioning frame 4-7, forms a stable positioning reference surface. Each time, only one side of the support frame 4-1 needs to be moved to complete the loading and unloading of the workpiece, ensuring both workpiece positioning accuracy and improving clamping efficiency. The operator can quickly adjust the linear position of the positioning frame 4-7 using the crank handle 4-11 and precisely control the position of the support frame 4-1 using the internal threaded sleeve 4-4, achieving rapid positioning and secure clamping of the workpiece. This ensures workpiece stability during drilling, avoiding hole position deviations caused by vibration or displacement, and provides reliable clamping protection for the high-precision machining of the double-hole spring 4-8 seat.

[0041] like Figures 1-4 As shown in the figure, the waste collection and discharge component 5 in this embodiment includes a cleaning port 5-1, which is opened on the surface of the frame 1. A collection cover 5-2 is provided at the bottom of the frame 1. A discharge pipe 5-3 is provided on one side of the collection cover 5-2. A pusher auger 5-4 is installed in the collection cover 5-2 and the discharge pipe 5-3.

[0042] In some examples, to achieve the effect of collecting and centrally discharging waste, a waste collection and discharge assembly 5 is designed. This assembly includes a cleaning port 5-1 on the surface of the frame 1, located below the central frame 8, and communicating with the interior of the collection hood 5-2 for easy periodic cleaning of accumulated waste. The collection hood 5-2 is funnel-shaped and fixed to the bottom of the frame 1. Its inclined inner wall guides the waste to gather towards the discharge pipe 5-3, and the increased opening area can effectively collect the debris that falls during drilling. The discharge pipe 5-3 is horizontally connected to one side of the collection hood 5-2. The pusher auger 5-4 installed inside is fixed to both ends of the pipe by bearings. Its spiral blades maintain a small gap with the inner wall of the pipe to ensure smooth conveying of waste.

[0043] The axial thrust generated by the motor-driven rotation pushes the waste chips inside the collection hood 5-2 along the discharge pipe 5-3 to the external collection device. When the drilling machine is working, the waste chips generated during drilling fall into the collection hood 5-2 through the gap in the central frame 8. Under the action of gravity, they converge towards the bottom of the funnel, pushing the auger 5-4 to continue operating and discharging the waste chips from the discharge pipe 5-3, thus preventing the accumulation of waste chips from affecting the operation of the equipment.

[0044] This component achieves efficient chip collection through the funnel structure of the collection hood 5-2 and continuous chip removal through the spiral drive of the push auger 5-4, ensuring timely cleaning of metal or non-metal chips generated during drilling, keeping the work area clean, reducing the impact of chips on workpiece positioning accuracy, reducing the cleaning workload of operators, and improving the automation and practicality of the equipment.

[0045] For example, such as Figure 1 As shown, the outer surface of the internal threaded sleeve 4-4 is provided with an anti-slip protrusion 6.

[0046] In some examples, the anti-slip raised layer 6 on the outer surface of the internal threaded sleeve 4-4 adopts a raised ribbed or granular structure to closely fit the operator's hand. When the internal threaded sleeve 4-4 is rotated to fine-tune the position of the support frame 4-1, the anti-slip raised layer 6 increases the friction, prevents the hand from slipping, ensures a smooth and precise rotation process, improves the operator's control accuracy over the lateral position adjustment of the support frame 4-1, and helps to achieve precise clamping and positioning of the workpiece.

[0047] For example, such as Figure 1 As shown, a pair of tilting platforms 7 are provided on the top of the support frame 4-1, and the tilting platforms 7 are located on both sides of the connection between the support frame 4-1 and the stud 4-5.

[0048] In some examples, a pair of inclined platforms 7 on the top of the support frame 4-1 are located on both sides of the connection between the support frame 4-1 and the stud 4-5, and are inclined towards the stud 4-5 in a sloping shape. The inclined platforms 7 can guide the waste chips generated during drilling to slide down the slope, avoiding the accumulation of waste chips at the connection between the stud 4-5 and the internal threaded sleeve 4-4, preventing waste chips from affecting the thread transmission between the stud 4-5 and the internal threaded sleeve 4-4, ensuring smooth movement of the support frame 4-1, and at the same time reducing the wear of waste chips on the positioning and clamping assembly 4, extending its service life.

[0049] In practical use: Fix frame 1 to the work site, install gantry frame 2 on frame 1, connect drilling motor 3 to gantry frame 2 via vertical linear drive device (lead screw), and fix central frame 8 to the surface of frame 1. According to the specifications of the double-hole spring 4-8 seat, rotate the internal threaded sleeves 4-4 on both sides of central frame 8. The studs 4-5 drive support frame 4-1 to slide along transmission groove 4-2, adjusting the distance between the two support frames 4-1 to align the mounting plate 4-3 with the workpiece. Pull the positioning frame 4-7 along the movable rod 4-6, compressing spring 4-8 to generate preload, fixing the positioning frame 4-7 in a suitable position. Secure the positioning frame 4-7 by cranking the fastening bolts 4-10 using the crank handle 4-11. Place the workpiece on support frame 4-1, position it using mounting plate 4-3, and fine-tune the internal threaded sleeves 4-4 again to clamp the workpiece between support frame 4-1 and positioning frame 4-7. Start the drilling motor 3, and the vertical linear drive will drive it to descend and drill. The generated waste chips fall into the collection hood 5-2 through the gap of the central frame 8. The auger 5-4 pushes the waste chips to the outside along the discharge pipe 5-3. After processing, the reverse operation is used to release the workpiece, and the equipment is cleaned through the cleaning port 5-1.
