Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, and in particular to a polishing equipment for precision steel pipe processing. Background Technology

[0002] Precision steel pipe is a high-precision steel pipe material produced through cold drawing or hot rolling. Due to its advantages such as no oxide layer on the inner and outer walls, high pressure resistance without leakage, high precision, high surface finish, no deformation after cold bending, and no cracks after flaring and flattening, it is mainly used to produce pneumatic or hydraulic components, such as cylinders or oil cylinders. It can be seamless or welded. After processing, the precision steel pipe needs to be cut to the required length. After cutting, the cut surfaces need to be polished to avoid burrs. However, current polishing equipment cannot effectively collect the dust generated during the polishing process, causing dust to drift freely in the workshop, polluting the environment and requiring manual cleaning by workers, increasing their workload. Utility Model Content

[0003] This utility model discloses a polishing device for precision steel pipe processing, which solves the problem of not being able to effectively collect the dust generated during the polishing process of precision steel pipes.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A polishing device for precision steel pipe processing includes a base, a worktable on top of the base, and a fixing assembly for clamping and fixing the steel pipe on the worktable. A cover is provided on one side of the worktable, and a polishing wheel is located inside the cover. A motor for driving the polishing wheel is mounted on the cover. The side of the cover closest to the worktable is open and has two symmetrical baffles. A semi-circular groove is formed on the side of the two baffles that is close to each other, and an arc-shaped plate is placed inside the semi-circular groove. A sponge pad is fixed to the inner wall of the arc-shaped plate. Two electric telescopic rods are provided on the cover to drive the movement of the baffles. A vacuum cleaner is provided on the base to suck up dust from inside the cover.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] After placing the precision steel tube on the workbench, the cut end of the tube enters the housing and contacts the polishing wheel. The tube is then clamped and secured using a fixing assembly. Next, two electric telescopic rods are activated, driving two baffles to move towards the tube and clamp it. The sponge pads on the inner walls of the two curved plates then adhere to the outer wall of the tube, sealing the polishing area. The first motor is then activated to drive the polishing wheel, polishing the tube. Simultaneously, a vacuum cleaner is activated to suck in the dust generated inside the housing. This invention effectively collects dust generated during the polishing process, preventing it from scattering freely in the workshop, ensuring a clean environment, and reducing the workload of workers.

[0013] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0014] like Figure 1 , Figure 3 and Figure 4As shown, this utility model provides a polishing device for precision steel pipe processing, including a base 1, a worktable 2 above the base 1, a fixing component for clamping and fixing the steel pipe on the worktable 2; a cover 4 on one side of the worktable 2, a polishing wheel 5 inside the cover 4, a motor 51 for driving the polishing wheel 5 on the cover 4, the side of the cover 4 near the worktable 2 is open and has two baffles 6 arranged symmetrically front and back, a semi-circular groove is opened on the side of the two baffles 6 that are close to each other, an arc plate 61 is provided in the semi-circular groove, and a sponge pad 62 is fixed on the inner wall of the arc plate 61; two electric telescopic rods 7 are provided on the cover 4 for driving the movement of the baffles 6 respectively, and a vacuum cleaner 8 is provided on the base 1 for sucking up the dust inside the cover 4. After placing the precision steel pipe on the workbench 2, the cut end of the precision steel pipe enters the housing 4 and contacts the polishing wheel 5. The top of the housing 4 has ventilation holes and a filter screen that blocks the ventilation holes (the filter screen and ventilation holes are not shown in the figure). Then, the precision steel pipe is clamped and fixed using the fixing components. Then, the two electric telescopic rods 7 are activated, so that the two baffles 6 come together and the sponge pad 62 on the inner wall of the arc plate 61 contacts the outer wall of the precision steel pipe, sealing the housing 4. Then, the first motor 51 is activated to drive the polishing wheel to rotate and polish the end of the precision steel pipe. At the same time, the vacuum cleaner 8 is activated so that the dust generated during the polishing operation is sucked into the vacuum cleaner 8, preventing the dust from being scattered randomly in the production workshop.

[0015] like Figure 1 and Figure 2 As shown, the fixing assembly includes two sets of symmetrically arranged, vertically positioned abutment plates 3. Each side of the worktable 2 has an opening 21 that matches the abutment plates 3. Two sets of symmetrically arranged hydraulic rods 31 are fixed to the base 1. Two movable plates 32 are slidably connected to the base 1. The two movable plates 32 are respectively fixed to the telescopic ends of the two sets of hydraulic rods 31, and the tops of the two movable plates 32 are respectively fixed to the bottoms of the two sets of abutment plates 3. After placing the precision steel pipe on the worktable 2, the two sets of hydraulic rods 31 can be activated, driving the two movable plates 32 closer together. This causes the two sets of abutment plates 3 to move towards the openings 21 and then close together, thus securing the precision steel pipe.

[0016] like Figure 1 and Figure 2As shown, an automatic telescopic rod 22 is fixed to the top of the workbench 2. A positioning plate 23 is fixed to the telescopic end of the automatic telescopic rod 22, located between two sets of openings 21. A rubber pad is fixed to one side of the positioning plate 23. When the precision steel pipe is fixed by the two sets of abutment plates 3, one end of the precision steel pipe corresponds to the positioning plate 23. Then, the automatic telescopic rod 22 is activated, causing the positioning plate 23 to move towards the precision steel pipe, thus abutting one end of the precision steel pipe and further improving the fixing effect. The abutment plate 3 is equipped with the same rubber pad as the positioning plate 23. The rubber pad protects the precision steel pipe and increases the friction between the abutment plate 3, the positioning plate 23, and the precision steel pipe, thus better fixing the precision steel pipe.

[0017] like Figure 1 and Figure 4 As shown, a fixing block 63 and a connecting block 64 are respectively fixed on the arc-shaped plate 61 and the baffle 6. A screw 65 connected to the connecting block 64 is threaded onto the fixing block 63. A positioning rod 66 is fixed on the fixing block 63, and a positioning hole adapted to the positioning rod 66 is provided on the connecting block 64. The fixing block 63 and the connecting block 64 are located on the side of the arc-shaped plate 61 and the baffle 6 away from the polishing wheel 5, respectively. When it is necessary to repair or replace the arc-shaped plate 61 or the sponge pad 62, the screw 65 can be removed, the arc-shaped plate 61 and the baffle 6 can be separated, and a new arc-shaped plate 61 and a new sponge pad 62 can be replaced.

[0018] like Figure 1 , Figure 3 and Figure 4 As shown, a rotating rod 52, which passes through the housing 4 and is connected to the polishing wheel 5, is fixed on the shaft of the first motor 51. A bearing block 53, which is connected to the housing 4, is fixed on the main body of the first motor 51. A connecting rod 71, which is connected to the baffle 6, is fixed to the telescopic end of the electric telescopic rod 7. The bearing block 53 can support the first motor 51. After the first motor 51 is started, the polishing wheel 5 can be driven to rotate through the rotating rod 52 to polish the precision steel pipe. After the electric telescopic rod 7 is started, the telescopic end of the electric telescopic rod 7 can drive the baffle 6 to move through the connecting rod 71, so that the two baffles 6 move closer or further apart. The fixed end of the electric telescopic rod 7 is fixed to the housing 4.

[0019] like Figure 1As shown, a sliding plate 9 is slidably connected to the top of the base 1. A second motor 91 is fixed on the base 1, and a lead screw 92 threadedly connected to the sliding plate 9 is fixed to the shaft of the second motor 91. A second automatic telescopic rod 93 connected to the bearing block 53 is fixed to the top of the sliding plate 9. A support leg is fixed between the worktable 2 and the base 1. The end of the lead screw 92 away from the second motor 91 is rotatably connected to a support leg. When the precision steel pipe is fixed on the worktable 2, the second motor 91 (which is a servo motor) can be started to drive the lead screw 92 to rotate. The sliding plate 9 can then move closer to or further away from the worktable 2. The second automatic telescopic rod 93 can then move the cover 4 through the bearing block 53, so that the cut end of the precision steel pipe can enter the cover 4 and contact the polishing wheel 5, without needing to... Workers move the precision steel pipe so that one end of the cut precision steel pipe enters the housing 4. When polishing precision steel pipes of different diameters, the arc plate 61 can be disassembled and replaced with an arc plate 61 that matches the precision steel pipe. After the arc plate 61 is replaced, the second automatic telescopic rod 93 is activated to move the housing 4 up or down so that the axis of the precision steel pipe can correspond to the axis of the polishing wheel 5, so that the two replaced arc plates 61 can better clamp and seal the precision steel pipe.

[0020] like Figure 1 and Figure 3 As shown, the vacuum cleaner 8 is fixed on the slide plate 9. The suction end of the vacuum cleaner 8 is connected to a flexible hose, and the other end of the hose is connected to a dust collection hood 81 that is connected to the bottom of the housing 4. The bottom of the housing 4 is inclined towards the dust collection hood 81. The vacuum cleaner 8 is a very mature existing technology, and staff can select and use it according to the vacuum cleaners 8 available on the market, so it will not be described in detail here. The setting of the flexible hose at the suction end of the vacuum cleaner 8 will not affect the normal raising and lowering of the housing 4. After the vacuum cleaner 8 is started, the dust collection hood 81 can generate suction to suck the dust generated during the polishing of the precision steel pipe inside the housing 4 into the vacuum cleaner 8 for subsequent unified treatment by staff. The bottom of the housing 4 is inclined so that the dust falling to the bottom of the housing 4 can slide towards the dust collection hood 81.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
