Description

Technical Field

[0001] This invention relates to the field of pipe fitting crimping technology, specifically to an adjustable hydraulic pipe fitting crimping machine. Background Technology

[0002] A hydraulic hose fitting crimping machine is a hydraulic device used to crimp hydraulic hose fittings assemblies. Its main function is to ensure a strong and sealed connection between the hose and the fitting through crimping (or pressing) to prevent leakage. It is widely used in engineering machinery, vehicle manufacturing, coal mining, home appliances and other fields.

[0003] However, existing hydraulic hose fitting crimping machines still have some problems in practical use: their structure is relatively fixed, making it impossible to flexibly adjust the shrinkage of the crimped hydraulic hose fitting according to crimping requirements; secondly, since hydraulic hose fittings have different diameters, it is necessary to select a crimping machine with a matching diameter, resulting in generally poor overall flexibility and performance. Therefore, we propose an adjustable hydraulic hose fitting crimping machine to solve the above problems. Summary of the Invention

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example: Figure 1-9 As shown, the present invention provides an adjustable hydraulic pipe fitting crimping machine, including a mounting bracket 1, an outer frame 2 fixedly mounted on the top of the mounting bracket 1, a middle frame 21 provided in the outer frame 2, an inner frame 22 provided in the middle frame 21, a first cover 23 fixedly mounted on both ends of the outer frame 2 and the middle frame 21, a second cover 24 fixedly mounted on both ends of the inner frame 22 and the middle frame 21, and a plurality of crimping mechanisms 3 arranged in a ring array between the middle frame 21 and the inner frame 22, with a first crimping plate 4 provided on the opposite ends of the plurality of crimping mechanisms 3;

[0033] The clamping mechanism 3 includes a telescopic slide 31. A first slot 201 corresponding to the clamping mechanism 3 is provided on the inner frame 22 of the mechanism. One end of the telescopic slide 31 is slidably engaged in the first slot 201. A second slot 202 corresponding to the clamping mechanism 3 is provided on the middle frame 21 of the mechanism. The other end of the telescopic slide 31 is slidably engaged in the second slot 202. A drive slide 32 is fixedly installed at the end of the telescopic slide 31 near the middle frame 21 of the mechanism. The end of the telescopic slide 31 away from the drive slide 32 extends into the inner frame 22 of the mechanism and is fixedly installed with a mounting frame 33. A guide sleeve 311 is fixedly installed on the side of the telescopic slide 31 away from the mounting frame 33. A guide shaft 312 is movably inserted in the middle of the guide sleeve 311. The guide shaft 312 is fixedly engaged between the middle frame 21 of the mechanism and the inner frame 22 of the mechanism.

[0034] Mounting strips 331 are fixedly installed on the outer side of the first clamping plate 4. The mounting strips 331 are slidably engaged in the mounting frame 33. Fixing bolts 332 are movably inserted into the mounting strips 331. The ends of the fixing bolts 332 are threaded onto the mounting frame 33 to engage and fix the first clamping plate 4 and the clamping mechanism 3, thereby facilitating the removal of the fixing bolts 332 and the mounting strips 331 and removing the first clamping plate 4 from the mounting frame 33.

[0035] The clamping mechanism 3 also includes a first slide block 34, which is fixedly installed on the outer wall of the middle frame 21 of the mechanism near the telescopic slide 31. Both ends of the first slide block 34 are slidably inserted with drive horizontal shafts 341. Drive pins 342 are vertically installed on the ends of the two drive horizontal shafts 341 near the telescopic slide 31. Drive grooves 321 corresponding to drive pins 342 are opened on the drive slide block 32. Drive pins 342 are movably engaged in the corresponding drive grooves 321. Rotary sleeves 343 are rotatably sleeved on the outer side of the drive pins 342. The outer wall of the rotating sleeves 343 is in contact with the inner wall of the drive grooves 321.

[0036] Two drive shafts 341 are vertically mounted with a first mounting base 35 at one end away from the drive clamping shaft 342. A first cylinder seat 351 is fixedly mounted on the outer wall of the mechanism frame 21 near the first mounting base 35. A first telescopic cylinder 352 is fixedly mounted on the first cylinder seat 351. The drive end of the first telescopic cylinder 352 is fixedly mounted to the middle of the first mounting base 35. The hydraulic oil pipe joint is placed between multiple first clamping plates 4. By controlling the extension of multiple first telescopic cylinders 352, the first mounting base 35, the two drive shafts 341, the drive clamping shaft 342, and the rotating sleeve 343 are driven to translate a certain distance. Since the drive clamping shaft 342 is movably engaged in the corresponding drive inclined groove 321, the drive clamping shaft 342 drives multiple drive slides 32 to move towards each other a certain distance, thereby controlling multiple telescopic slides 31 and mounting frame 33 to move towards each other a certain distance, and then driving multiple first clamping plates 4 to move towards each other a certain distance, so as to perform automatic clamping operation on the hydraulic oil pipe joint placed between multiple first clamping plates 4.

[0037] The crimping mechanism 3 also includes a second slide 36, which is fixedly installed on the outer wall of the middle frame 21 of the mechanism near the telescopic slide 31. The drive slide 32 is located between the first slide 34 and the second slide 36. Positioning crossbars 361 are slidably inserted at both ends of the second slide 36. The position of the positioning crossbars 361 corresponds horizontally to the position of the drive horizontal shaft 341. By setting the positioning crossbars 361, the translation amount of the drive horizontal shaft 341 can be limited, thereby improving the accuracy of the translation distance of the drive horizontal shaft 341, and thus improving the accuracy of the relative movement distance of the multiple first crimping plates 4. This allows for precise measurement of the shrinkage amount of the automatic crimping of the hydraulic oil pipe joint by the multiple first crimping plates 4, thereby improving the crimping quality of the hydraulic oil pipe joint.

[0038] Two positioning crossbars 361 are vertically mounted with a second mounting base 37 at their ends away from the drive slide 32. A second cylinder seat 371 is fixedly mounted on the outer wall of the mechanism frame 21 near the second mounting base 37. A second telescopic cylinder 372 is fixedly mounted on the second cylinder seat 371. The drive end of the second telescopic cylinder 372 is fixedly mounted to the middle of the second mounting base 37. Before use, the translation distance of the drive crossbar 341 is adjusted according to the shrinkage amount of the hydraulic oil pipe joint. By controlling the extension of multiple second telescopic cylinders 372, the second mounting base 37 and the two positioning crossbars 361 are moved towards the side closer to the drive crossbar 341. This precisely reduces the translation distance of the drive horizontal axis 341, thereby reducing the shrinkage amount of the automatic crimping of the hydraulic hose connector by the multiple first crimping plates 4. Conversely, by controlling the retraction of the multiple second telescopic cylinders 372 to drive the second mounting base 37 and the two positioning horizontal columns 361 to move away from the drive horizontal axis 341, the translation distance of the drive horizontal axis 341 is precisely increased, thereby increasing the shrinkage amount of the automatic crimping of the hydraulic hose connector by the multiple first crimping plates 4. This allows for flexible adjustment of the shrinkage amount of the automatic crimping of the hydraulic hose connector, thereby improving the crimping accuracy of the hydraulic hose connector and enhancing the overall performance of the crimping machine.

[0039] A first oil inlet main pipe 7 and a first oil return main pipe 71 are provided on the outer wall of the mechanism frame 21 near the first telescopic oil cylinder 352. A first connecting pipe 72 is provided on the first oil inlet main pipe 7, and a second connecting pipe 711 is provided on the first oil return main pipe 71. The first connecting pipe 72 and the second connecting pipe 711 are fixedly snapped onto the mechanism frame 2. In use, the ends of the first connecting pipe 72 and the second connecting pipe 711 are connected to the output port and the input port of the oil supply system, respectively. A first oil inlet branch pipe 701 corresponding to the positions of multiple clamping mechanisms 3 is fixedly installed on the inner side of the first oil inlet main pipe 7. The ends of the first oil inlet branch pipes 701 are connected to the corresponding clamping mechanisms 3. The oil inlet of the first cylinder seat 351 is fixedly installed. The inner side of the first return oil main pipe 71 is fixedly installed with the first return oil branch pipe 702 corresponding to the positions of the multiple clamping mechanisms 3. The end of the first return oil branch pipe 702 is fixedly installed with the oil outlet of the first cylinder seat 351 in the corresponding clamping mechanism 3. By controlling the opening of the oil supply system, the oil is supplied through the output port, the first connecting pipe 72, the first oil inlet main pipe 7 and the multiple first oil inlet branch pipes 701, and the multiple first telescopic cylinders 352 are synchronously introduced into the multiple first telescopic cylinders 352, and the multiple first telescopic cylinders 352 are controlled to extend synchronously. Conversely, by controlling the opening of the oil supply system to suck oil, the multiple first telescopic cylinders 352 are controlled to retract synchronously.

[0040] A second oil inlet main pipe 8 and a second oil return main pipe 81 are provided on the outer wall of the mechanism frame 21 near the second telescopic oil cylinder 372. A third connecting pipe 82 is provided on the second oil inlet main pipe 8, and a fourth connecting pipe 811 is provided on the second oil return main pipe 81. The third connecting pipe 82 and the fourth connecting pipe 811 are fixedly snapped onto the mechanism frame 2. In use, the ends of the third connecting pipe 82 and the fourth connecting pipe 811 are connected to the output port and the input port of the oil supply system, respectively. A second oil inlet branch pipe 801 corresponding to the positions of multiple clamping mechanisms 3 is fixedly installed on the inner side of the second oil inlet main pipe 8. The ends of the second oil inlet branch pipes 801 are connected to the corresponding clamping mechanisms 3. The oil inlet of the two telescopic cylinders 372 is fixedly installed. The inner side of the second return oil main pipe 81 is fixedly installed with a second return oil branch pipe 802 corresponding to the position of the multiple clamping mechanisms 3. The end of the second return oil branch pipe 802 is fixedly installed with the oil outlet of the corresponding second telescopic cylinder 372 in the clamping mechanism 3. By controlling the opening of the oil supply system, the oil is simultaneously introduced into the multiple second telescopic cylinders 372 through the output port, the third connecting pipe 82, the second oil inlet main pipe 8 and the multiple second oil inlet branch pipes 801, controlling the multiple second telescopic cylinders 372 to extend synchronously. Conversely, by controlling the opening of the oil supply system to suck oil, the multiple second telescopic cylinders 372 are controlled to retract synchronously.

[0041] The crimping machine also includes multiple second crimping plates 5 arranged in a ring array. The connection method between the second crimping plates 5 and the mounting frame 33 is the same as the connection method between the first crimping plate 4 and the mounting frame 33. The crimping machine also includes multiple third crimping plates 6 arranged in a ring array. The connection method between the third crimping plates 6 and the mounting frame 33 is the same as the connection method between the first crimping plate 4 and the mounting frame 33. By setting the first crimping plate 4, the second crimping plate 5, and the third crimping plate 6, the corresponding first crimping plate 4, second crimping plate 5, or third crimping plate 6 can be selected and fixed according to the different diameters of the hydraulic oil pipe joints. This facilitates the crimping operation of hydraulic oil pipes of different diameters by moving multiple first crimping plates 4, multiple second crimping plates 5, or multiple third crimping plates 6 in opposite directions, thereby improving the overall flexibility of the crimping machine.

[0042] Working principle: In use, connect the end of the first connecting pipe 72 and the end of the second connecting pipe 711 to the output port and the input port of the oil transportation system, respectively, and connect the end of the third connecting pipe 82 and the end of the fourth connecting pipe 811 to the output port and the input port of the oil transportation system, respectively.

[0043] Subsequently, depending on the diameter of the hydraulic oil pipe connector, the corresponding first clamping plate 4, second clamping plate 5, or third clamping plate 6 is selected for snap-fit ​​fixing.

[0044] Before crimping, the translation distance of the drive horizontal shaft 341 is adjusted according to the shrinkage amount of the hydraulic hose connector crimping. By controlling the extension of multiple second telescopic cylinders 372, the second mounting base 37 and the two positioning horizontal columns 361 are moved closer to the drive horizontal shaft 341, thereby precisely reducing the translation distance of the drive horizontal shaft 341. This reduces the shrinkage amount of the automatic crimping of the hydraulic hose connector by multiple first crimping plates 4. Conversely, by controlling the retraction of multiple second telescopic cylinders 372, the second mounting base 37 and the two positioning horizontal columns 361 are moved away from the drive horizontal shaft 341, thereby precisely increasing the translation distance of the drive horizontal shaft 341. This increases the shrinkage amount of the automatic crimping of the hydraulic hose connector by multiple first crimping plates 4, until the shrinkage amount is adjusted.

[0045] Subsequently, the hydraulic hose connector is placed between multiple first clamping plates 4 or multiple second clamping plates 5 or multiple third clamping plates 6;

[0046] By controlling the start of the oil supply system, oil is simultaneously introduced into multiple first telescopic cylinders 352 through the output port, first connecting pipe 72, first main oil inlet pipe 7, and multiple first branch oil inlet pipes 701. The multiple first telescopic cylinders 352 are controlled to extend synchronously, driving the first mounting base 35 and two drive horizontal shafts 341 to translate until the drive horizontal shafts 341 contact the corresponding positioning horizontal column 361. The translation distance of the drive locking shaft 342 and the rotating sleeve 343 is positioned. Since the drive locking shaft 342 is movably locked in the corresponding drive inclined groove 321, the drive locking shaft 342 drives multiple drive slides 32 to move towards each other by a certain distance, thereby controlling multiple telescopic slides 31 and mounting frame 33 to move towards each other by a certain distance. This, in turn, drives multiple first clamping plates 4 or multiple second clamping plates 5 or multiple third clamping plates 6 to move towards each other by a certain distance, performing automatic clamping operation on the hydraulic oil pipe joint.
