Technical Field

[0001] This utility model relates to the field of hydraulic pipe joint polishing technology, specifically a hydraulic pipe joint polishing device. Background Technology

[0002] Hydraulic pipe fittings are two accessories that connect different hydraulic components (pumps, transport pipelines, directional valves, liquid hydrogen, hydraulic generators, hydraulic cylinders, and some remote components, such as level gauges, ultrasonic sensors, and pressure gauges) to form two semi-closed circuits in a hydraulic control system. They serve as two connecting and facilitating components.

[0003] Due to the irregular shape of the outer wall of the hydraulic pipe joint, current polishing equipment has great limitations in polishing the irregular outer wall of the hydraulic pipe joint. At the same time, the outer wall of the hydraulic pipe joint will also be damaged to some extent due to mechanical pressure during the polishing process.

[0004] In view of this, a hydraulic pipe joint polishing device was designed to solve the above problems. Utility Model Content

[0005] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0030] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0031] The following describes, with reference to the accompanying drawings, some embodiments of a hydraulic pipe joint polishing device provided by this utility model. Example

[0032] Combination Figures 1 to 5As shown, the present invention provides a hydraulic pipe joint polishing device, including a joint body 100, a positioning component 200 disposed inside the joint body 100, multiple polishing components 300 installed outside the joint body 100, and a power supply component 400 installed on the multiple polishing components 300. The positioning component 200 is used to provide a support platform for the joint body 100 before polishing, the power supply component 400 is used to provide polishing kinetic energy to the multiple polishing components 300, and the multiple polishing components 300 are used to polish the outer wall of the joint body 100.

[0033] The positioning assembly 200 includes a clamp 230, a column 220 fixedly installed inside the clamp 230, and two housings 210 disposed outside the column 220;

[0034] The polishing assembly 300 includes a main polishing component 310 adapted to fit onto the outer wall of the connector body 100 and a secondary polishing component 3103 installed inside the main polishing component 310.

[0035] The power supply assembly 400 includes a shaft 410 inserted into the outer end of the column 220, a sliding column 4104 installed outside the shaft 410, a sleeve 4105 movably installed outside the sliding column 4104, a column head 4106 inserted into the sleeve 4105 and snapped into the sliding groove of the sliding column 4104, a bracket 4103 movably installed on the column head 4106, a secondary sliding sleeve 4102 fixedly installed at the other end of the bracket 4103, a pull rod 430 movably installed on the secondary sliding sleeve 4102 and fixedly installed inside the main polishing part 310, a main sliding sleeve 4101 movably installed on the shaft 410, an outer frame 420 movably installed on the main sliding sleeve 4101, and an adapter 4201 movably installed at the other end of the outer frame 420, with the shaft 410 movably installed inside the adapter 4201. A washer is fixedly installed on the outside of the shaft 410, and a compression spring 440 is fixedly connected to the washer.

[0036] The other end of the compression spring 440 is fixedly mounted on the adapter 4201.

[0037] Before use, the main slide sleeve 4101 is stretched outward along the shaft 410. At this time, the outer frame 420 movably installed on the main slide sleeve 4101 will pull the pull rod 430 to flip outward, and the polishing component 300 installed on the pull rod 430 will move away from the outer shell 210.

[0038] After the two outer shells 210 are exposed, the connector body 100 to be processed is inserted into the outside of the two outer shells 210. Then, the screw 260 is adjusted to rotate forward with a screwdriver. The plug 250, which moves laterally along the threaded section of the screw 260, will squeeze the two anti-slip pads 2103. Finally, the two anti-slip pads 2103, together with the two outer shells 210, can quickly fix the connector body 100.

[0039] Next, control the main sliding sleeve 4101 to reset until the multiple polishing components 300 approach the two outer shells 210, until the multiple polishing components 300 are completely attached to the outer wall of the connector body 100. With the high-frequency vibration of the multiple polishing components 300, the connector body 100, which is finally in a fixed state, can be effectively polished. Example

[0040] Combination Figures 2 to 4 As shown, based on Embodiment 1, the positioning assembly 200 further includes bolts 2101 installed inside the two housings 210, a lead screw 260 movably installed inside the two housings 210, a limiting block 2104 fixedly installed on the lead screw 260, a plug 250 provided on the threaded section of the lead screw 260, two anti-slip pads 2103 inserted into the two housings 210, and a spring 2102 fixedly installed on the anti-slip pads 2103;

[0041] The beveled surface of the plug 250 is adapted to bear pressure on the inner wall of the two anti-slip pads 2103;

[0042] The column 220 has a T-shaped structure, and one end of the column 220 that extends to the outside of the clamp 230 has an insertion hole. The inner end of the shaft 410 is adapted to pass through the insertion hole, and the other end of the shaft 410 is inserted into the inside of the limiting frame 240.

[0043] The outer wall of the anti-slip mat 2103 has an arc-shaped groove.

[0044] Preferably, by fixing the clamp 230 on the workbench until the outer shell 210 and the shaft 410 and the clamp 230 are in a vertical state, the horizontal column 220 and the two outer shells 210 can provide a sufficiently stable support platform for the connector body 100 to be processed. After the connector body 100 is fixed, the multiple polishing components 300 evenly distributed on the outer wall of the connector body 100 can achieve uniform vibration in the transmission state. While improving the efficient polishing treatment of the irregular structure on the outer wall of the connector body 100, it can also avoid the waste material from clogging the holes inside the connector body 100. Example

[0045] Combination Figure 1 and Figure 2 As shown, based on Embodiment 1, the polishing assembly 300 further includes a main chuck 3101 and an end plate 3102 fixedly installed on the top of the main polishing component 310, a screw 320 movably installed inside the end plate 3102, a secondary chuck 3201 movably installed at the inner end of the screw 320, a secondary plate 3202 movably installed on the secondary chuck 3201, a main plate 3104 movably installed on the main chuck 3101, and a pressure block 330 movably installed between the secondary plate 3202 and the main plate 3104.

[0046] A rectangular slot is provided in the middle of the top surface of the main polishing part 310, and the bottom end of the pressure block 330 is adapted to penetrate into the rectangular slot.

[0047] The length of the main polishing component 310 is twice the length of the connector body 100, and the secondary polishing component 3103 is fitted and pressed into the groove on the outer wall of the connector body 100.

[0048] Preferably, both the main polishing component 310 and the secondary polishing component 3103 are equipped with abrasive belts on the side facing the connector body 100. As the screw 320 rotates forward, the secondary chuck 3201, which is pulled by the screw 320, will pull the secondary plate 3202 and the main plate 3104 to expand outward. Finally, the pressure block 330 will compress the secondary polishing component 3103 into the gap on the outer wall of the connector body 100.

[0049] As multiple polishing components 300 are driven, the main polishing component 310 and the auxiliary polishing component 3103, which are in a high-frequency vibration state, can efficiently polish the outer wall of the connector body 100.

[0050] The working principle and usage process of this utility model are as follows: An external drive provides driving force to the shaft 410. As the shaft 410 is driven, the sliding column 4104 installed outside the shaft 410 will drive the column head 4106 and the bracket 4103 to reciprocate. The secondary sliding sleeve 4102 fixed at the other end of the bracket 4103 will push multiple pull rods 430. Finally, the pull rods 430 will push the polishing assembly 300 to vibrate at high frequency. While the polishing assembly 300 vibrates at high frequency, multiple polishing assemblies 300 can be fitted and attached to the outer wall of the connector body 100 to perform polishing operations.

[0051] In order to improve the effective polishing treatment of the gap on the outer wall of the connector body 100, the adjusting screw 320 is rotated in the forward direction. The secondary chuck 3201, which is movably installed at the inner end of the screw 320, will drive the secondary plate 3202, the pressure block 330 and the main plate 3104 to apply pressure to the secondary polishing part 3103. Finally, the secondary polishing part 3103 will effectively fit into the gap on the outer wall of the connector body 100.

[0052] After the outer wall of the connector body 100 is polished, the main sliding sleeve 4101 is stretched outward along the shaft 410. The multiple outer frames 420 movably mounted on the main sliding sleeve 4101 will control the multiple evenly distributed pull rods 430 to flip outward, and the multiple evenly distributed polishing components 300 will quickly detach from the outer wall of the connector body 100. At this time, the connector body 100 will be in an exposed state. Then, the screw 260 is reversed by using a screwdriver. As the plug 250 loses the pressure on the two anti-slip pads 2103, the two anti-slip pads 2103 will eventually shrink towards the inner cavity of the two outer shells 210. The connector body 100 after processing can then be quickly disassembled.

[0053] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
