Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hydraulic cylinder processing, in particular to a boring device and method for hydraulic cylinder processing. BACKGROUND

[0002] The boring device can effectively remove the rough surface of the cylinder bore through precise cutting processing, ensure that the geometric parameters such as the diameter, roundness and coaxiality of the inner hole meet the design requirements, thereby improving the working efficiency and service life of the hydraulic cylinder. In addition, the boring process can also help to remove the internal stress caused by casting or forging process, reduce the risk of deformation, and provide a good foundation for subsequent grinding and polishing processes. The structure of the boring device usually includes main shaft, tool, support frame, feeding device and cooling system and other main parts. The main shaft is responsible for rotating the tool and transmitting power, the tool is used for cutting the cylinder bore, the support frame is used for fixing the workpiece, the feeding device controls the feeding speed and amount of the tool, and the cooling system reduces the cutting temperature during processing to prevent the tool from overheating.

[0003] As disclosed in the application publication No. CN118577846A, a guiding type boring device and method for a hydraulic oil cylinder includes a base, at least two cutter bars, and a clamping positioning device. The at least two cutter bars are arranged in parallel and at intervals and can rotate and move axially along the cutter bars at the same time. The base is provided with the clamping positioning device for mounting and fixing a to-be-processed base. The first cutter and the second cutter are detachably and fixedly mounted on each cutter bar. The first guide section of the to-be-processed base is provided with a first mounting space for mounting the first cutter on the outside of the first guide section. The second guide section of the to-be-processed base is provided with a second mounting space for mounting the second cutter on the outside of the second guide section. The hydraulic cylinder and the boring cutter are aligned through a lifting assembly to perform boring operation, and the hydraulic cylinder can be bidirectionally supported and guided to enable stable boring operation of the hydraulic cylinder. It can be seen that the existing oil cylinder boring technology and device operation method are basically the same, that is, the required inner hole shape and size are gradually formed through the combination of fixed workpieces, rotating cutters, and cutting processing. However, when the above technical solution is used for continuous boring operation of the inlet hole and the outlet hole of the hydraulic oil cylinder, the worker needs to perform at least two times of transposition and debugging work on the cylinder barrel of the hydraulic oil cylinder, that is, the worker needs to perform transposition and adjustment on the cylinder barrel after the first boring to perform the second boring operation. However, the cylinder barrel of the hydraulic oil cylinder is a long columnar workpiece, and the boring depth and length requirement is high. After each transposition, the operator needs to re-adjust and set the parameters of the equipment, which introduces new error factors, such as inaccurate positioning of the clamp, so that the two hole positions finally processed are not on the same horizontal extension line, the bored hole position does not meet the design requirement, the performance of the hydraulic oil cylinder is affected, and the workpiece needs to be disassembled and reassembled, the clamp needs to be adjusted, the cutter needs to be set, and the like, which not only consumes time but also affects the production progress. Especially in the case of mass production, frequent transposition and debugging will cause the production cycle to be prolonged and the overall production efficiency to be reduced. SUMMARY

After the boring point is determined, the swing arm synchronous pushing assembly is used to move the double-layer sliding clamping piece close to the double-layer fixed clamping piece until the cylinder barrel is fixed. At this time, the boring assembly is processed. After the processing is completed, the X-axis conveying and transposition mechanism continues to push the double-cylinder-position clamping assembly and the cylinder barrel, so that the boring assembly processes the next hole position, thereby solving the problems in the above background art.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] Embodiment 1, by Figures 1 to 3 The present invention includes a support frame 1, on one side of the outer wall of the support frame 1 is provided with a double-cylinder clamping assembly 3 for synchronously clamping two cylinders, double-layer fixed clamps 5 are installed on both sides of the top of the support frame 1, and a double-layer sliding clamp 6 is slidably installed inside the double-layer fixed clamp 5.

[0030] The side frame 8 is fixed on the other side outer wall of the support frame 1, and the outer wall of the side frame 8 is provided with a U-shaped frame 9 which is installed in a lifting manner, both sides of the top end of the U-shaped frame 9 are provided with Y-axis feeding assemblies 10, and the moving end of the Y-axis feeding assembly 10 is provided with a boring assembly 11; the control panel 4 which is electrically connected with the input end of the X-axis conveying displacement mechanism 2, the swing arm type synchronous counter pushing assembly 7, the Y-axis feeding assembly 10 and the boring assembly 11 is installed on the side outer wall of the support frame 1.

[0031] The Z-axis cylinder 12 is installed on the side outer wall of the side frame 8, and the piston rod top end of the Z-axis cylinder 12 is fixedly connected with the bottom end of the U-shaped frame 9; the Z-axis cylinder 12 is used to push the U-shaped frame 9, the Y-axis feeding assembly 10 and the boring assembly 11 to slide in the Z-axis direction until the output shaft central axis of the boring assembly 11 coincides with the horizontal straight reference surface of the cylinder barrel, so as to ensure the machining accuracy of the cylinder barrel hole position.

[0032] The boring method for hydraulic cylinder machining in the embodiment, like the boring device for hydraulic cylinder machining, comprises the following steps:

[0033] S101: The hydraulic cylinder barrel to be machined is cleaned, and the cleaned hydraulic cylinder barrel is placed between the double-layer fixed clamping piece 5 and the double-layer sliding clamping piece 6, and the one end of the cylinder barrel is clamped by the double-cylinder-position clamping assembly 3, then the cylinder barrel in the clamped state is moved in the X-axis direction by the X-axis conveying displacement mechanism 2, so as to ensure that the cutter of the boring assembly 11 is accurately aligned with the predetermined hole position;

[0034] S102: After confirming the correct position, the worker starts the swing arm type synchronous counter pushing assembly 7 by the control panel 4, and uses the swing arm type synchronous counter pushing assembly 7 to make the two double-layer sliding clamping pieces 6 synchronously close to the double-layer fixed clamping piece 5 until the cylinder barrel is firmly fixed, and the worker inputs the related parameters of boring, including the Y-axis feeding speed, the rotating speed of the boring assembly 11 and the boring depth, on the control panel 4;

[0035] S103: After confirming that all the settings are correct, the worker starts the device to begin boring machining, and the Y-axis feeding assembly 10 drives the boring assembly 11 to move in the Y-axis direction until the cutter of the boring assembly 11 completes the boring operation on the cylinder barrel;

[0036] S104: After the first hole site is finished, the worker controls the swing arm synchronous pushing assembly 7 through the control panel 4 to work, so that the swing arm synchronous pushing assembly 7 drives the two double-layer sliding clamping pieces 6 to synchronously move away from the double-layer fixed clamping piece 5, to release the clamping restriction of the cylinder, and the X-axis conveying displacement mechanism 2 pushes the double-cylinder clamping assembly 3 and the clamped cylinder to continue to move in the X-axis direction, until the cylinder is moved to the next hole site, after the cylinder is moved, the swing arm synchronous pushing assembly 7, the double-layer sliding clamping piece 6, and the double-layer fixed clamping piece 5 continue to clamp the cylinder twice, and the boring assembly 11 and the Y-axis feeding assembly 10 continue to bore, so as to form two hole sites on the same horizontal line of the cylinder body.

[0037] S105: After confirming that the machining is correct, the operator releases the clamping state of the double-cylinder clamping assembly 3 by using the control panel 4, and releases the clamp and takes out the cylinder.

[0038] Example two, based on example one, is given by Figure 4 、 Figure 5 and Figure 6 The double-cylinder clamping assembly 3 includes a T-shaped plate 301 installed on the moving end of the X-axis conveying displacement mechanism 2, two symmetrical elongated columns 302 installed on the outer wall of the T-shaped plate 301 close to the side of the support frame 1, and a four-jaw chuck 303 fixed at the end of the elongated column 302 away from the T-shaped plate 301. When the double-cylinder clamping assembly 3 synchronously clamps two cylinders to be machined, the worker fixes one end of the cylinder by using the four-jaw chuck 303 and ensures its stability, provides uniform clamping force by the four-jaw chuck 303, avoids workpiece deformation or loosening caused by single-cylinder clamping, and the elongated column 302 serves to increase the pushing distance of the X-axis conveying displacement mechanism 2;

[0039] The X-axis conveying displacement mechanism 2 is used to realize the movement of the workpiece in the horizontal direction during machining, and the fast movement can significantly shorten the positioning time of the workpiece and improve the overall machining efficiency;

[0040] The double-layer fixed clamping piece 5 includes two main clamping plates 501 fixed on one side of the top end of the support frame 1 and four steel columns 502 installed between the two main clamping plates 501. The main clamping plate 501 is provided with a triangular notch on the outer wall close to the vertical center reference surface of the support frame 1, and the triangular notch is provided with a tooth groove. The elongated column 302 and the main clamping plate 501 are made of alloy steel material;

[0041] The double-layer sliding clamping piece 6 comprises a guide seat 601 fixed on one of the steel columns 502, sliding rods 602 slidingly installed at both ends inside the guide seat 601, and a U-shaped end bracket 603 fixed on the same end of the two sliding rods 602. The two side outer walls of the U-shaped end bracket 603 are fixed with auxiliary clamping plates 604, and the side outer wall of the auxiliary clamping plate 604 close to the main clamping plate 501 is also provided with a triangular notch. The cylinder to be machined passes between the main clamping plate 501 and the auxiliary clamping plate 604 from the Y-axis direction. The double-layer design increases the contact area to provide stronger clamping force, ensures that the position of the workpiece does not change during machining, and effectively reduces vibration to improve the quality of the machined surface.

[0042] The swing arm type synchronous pushing assembly 7 comprises a rectangular cavity 101 arranged at one end inside the support frame 1, rotating shafts 702 rotatingly installed at both sides inside the rectangular cavity 101, straight swing arms 704 fixed at the top ends of the rotating shafts 702, and straight notches arranged on the surfaces of the straight swing arms 704. The bottom end of the U-shaped end bracket 603 is fixed with a downwardly extending protruding part 705, the end of the protruding part 705 passes through the straight notches. One end inside the support frame 1 is provided with a reduction motor 701 for driving one of the rotating shafts 702 to rotate. One end of the surface of the rotating shaft 702 is fixed with a gear 703, and the two gears 703 are meshed with each other.

[0043] When the swing arm type synchronous pushing assembly 7 works, the reduction motor 701 is started to work by the control panel 4. The rotary power of the reduction motor 701 is transmitted to the two rotating shafts 702 through the gears 703. At this time, the two rotating shafts 702 rotate synchronously and reversely, i.e. the two straight swing arms 704 swing towards each other. Since the protruding part 705 is located in the straight notches of the straight swing arms 704, the swing action of the straight swing arms 704 is converted into the linear motion of the U-shaped end bracket 603, the sliding rods 602, and the auxiliary clamping plates 604 in the Y-axis direction, i.e. the U-shaped end bracket 603 and the auxiliary clamping plates 604 move towards the main clamping plate 501 until the auxiliary clamping plates 604 and the main clamping plate 501 stably clamp the cylinder. This ensures uniform distribution of clamping force, avoids workpiece deformation caused by local over-tightening or over-loosening, and allows the operator to easily clamp and loosen, improving the convenience of operation.

[0044] In Example Three, based on Example Two, Figure 7 and Figure 8The Y-axis feeding assembly 10 comprises a track carrier 1001 fixed at the top end of the U-shaped frame 9, a double sleeve carriage 1002 slidingly installed on the upper surface of the track carrier 1001, and a Y-axis hydraulic cylinder 1003 installed on the outer wall of one side of the U-shaped frame 9, the piston rod top end of the Y-axis hydraulic cylinder 1003 is fixedly connected with the bottom end of the double sleeve carriage 1002, the boring assembly 11 is installed on the upper surface of the double sleeve carriage 1002, the inside of the double sleeve carriage 1002 is provided with a rectangular opening part, a connecting seat is slidingly installed in the inside of the rectangular opening part, the top end of the connecting seat is fixedly connected with the bottom end of the double sleeve carriage 1002, the piston rod top end of the Y-axis hydraulic cylinder 1003 is fixedly connected with the outer wall of one side of the connecting seat, the Y-axis hydraulic cylinder 1003 pushes the double sleeve carriage 1002 and the boring assembly 11 to slide in the Y-axis direction, so that the cutter of the boring assembly 11 forms a hole position on the cylinder barrel, and the boring assembly 11 can be adjusted according to different machining requirements to adapt to workpieces of different thicknesses and materials.

[0045] In use, the embodiment of the present application first cleans the hydraulic cylinder barrel to be processed, ensuring that there is no oil stain, rust or other impurities, so as to avoid affecting the machining precision, then places the cleaned hydraulic cylinder barrel between the double-layer fixed clamping piece 5 and the double-layer sliding clamping piece 6, and uses the double-cylinder-position clamping assembly 3 to ensure that one end of the cylinder barrel is clamped firmly. During this process, the operator needs to pay attention to the symmetry and clamping force of the clamp to prevent the workpiece from moving during processing. Then the X-axis conveying and shifting mechanism 2 is used to move the clamped cylinder barrel in the X-axis direction to ensure that the cutter of the boring assembly 11 is accurately aligned with the predetermined hole position. This step needs to be carefully adjusted to ensure the accuracy of each hole position. After confirming that the position is correct, the operator starts the swing arm synchronous counter-pushing assembly 7 through the control panel 4 to work. The swing arm synchronous counter-pushing assembly 7 is used to make the two double-layer sliding clamping pieces 6 synchronously approach the double-layer fixed clamping piece 5 until the cylinder barrel is firmly fixed. At this time, the operator needs to confirm the clamping state again to ensure that the cylinder barrel will not loosen during processing. The operator inputs the relevant parameters of boring, including the Y-axis feeding speed, the speed of the boring assembly 11 and the boring depth, on the control panel 4. These parameters need to be reasonably set according to the material properties and tool specifications to ensure the processing effect. After confirming that all settings are correct, the operator starts the device to begin boring processing. During this process, the Z-axis cylinder 12 will gradually control the Z-axis height of the U-shaped frame 9, the Y-axis feeding assembly 10 and the boring assembly 11 according to the set boring parameters. The Y-axis feeding assembly 10 drives the boring assembly 11 to move in the Y-axis direction until the cutter of the boring assembly 11 completes the boring operation on the cylinder barrel. During the processing, the operator needs to monitor the running state of the device at all times, observe the cutting condition of the cutter and the reaction of the workpiece. If abnormalities are found, such as abnormal cutting sound or excessive cutting chips, the processing needs to be paused immediately for inspection and adjustment. After the hole position is bored out, the operator controls the swing arm synchronous counter-pushing assembly 7 through the control panel 4 to work, so that the swing arm synchronous counter-pushing assembly 7 drives the two double-layer sliding clamping pieces 6 to synchronously move away from the double-layer fixed clamping piece 5 to release the clamping restriction of the cylinder barrel. The X-axis conveying and shifting mechanism 2 is used to continue moving the double-cylinder-position clamping assembly 3 and the clamped cylinder barrel in the X-axis direction until the cylinder barrel is moved to the next hole position. After the cylinder barrel is moved, the swing arm synchronous counter-pushing assembly 7, the double-layer sliding clamping piece 6 and the double-layer fixed clamping piece 5 continue to clamp and fix the cylinder barrel for the second time, and the boring assembly 11 and the Y-axis feeding assembly 10 continue to bore, so as to form two hole positions on the same horizontal straight line of the cylinder barrel body. After confirming that the processing is correct, the operator releases the clamping state of the double-cylinder-position clamping assembly 3 by using the control panel 4, loosens the clamp and takes out the cylinder barrel. After taking out the cylinder barrel, the operator needs to clean it to remove the surface cutting chips and oil stains for subsequent inspection or assembly.

4. A boring method for hydraulic cylinder machining, comprising the boring device for hydraulic cylinder machining according to any one of claims 1 to 3, characterized in that: The following steps are involved: S101: The hydraulic cylinder barrel to be processed is cleaned and placed between a double-layer fixed fixture (5) and a double-layer sliding fixture (6), and a double-position clamping assembly (3) is used to ensure that one end of the cylinder barrel is firmly clamped. Then, the operator moves the clamped cylinder barrel in the X-axis direction through the X-axis conveying and shifting mechanism (2) to ensure that the tool of the boring assembly (11) is accurately aligned with the predetermined hole position; S102: After confirming that the position is correct, the staff starts the swing arm synchronous push assembly (7) through the control panel (4) to work, and uses the swing arm synchronous push assembly (7) to make the two double-layer sliding clamps (6) synchronously approach the double-layer fixed clamp (5) until the cylinder is firmly fixed. The staff enters the relevant parameters of boring on the control panel (4), including the Y-axis feed speed, the rotation speed of the boring assembly (11), and the boring depth; S103: After confirming that all settings are correct, the operator starts the device and begins boring processing. The Y-axis feed assembly (10) drives the boring assembly (11) to move in the Y-axis direction until the tool of the boring assembly (11) completes the boring operation on the cylinder barrel; S104: After the first hole position is waded out, the staff controls the swing arm synchronous pushing assembly (7) through the control panel (4) to work, so that the swing arm synchronous pushing assembly (7) drives the two double-layer sliding clamps (6) to synchronously move away from the double-layer fixed clamp (5) to release the clamping restriction of the cylinder, and uses the X-axis conveying and shifting mechanism (2) to push the double-cylinder clamping assembly (3) and the clamped cylinder to continue moving in the X-axis direction until the cylinder is moved to the next hole position. After the cylinder is moved, the swing arm synchronous pushing assembly (7), the double-layer sliding clamp (6), and the double-layer fixed clamp (5) continue to clamp the cylinder for the second time, and the boring assembly (11) and the Y-axis feeding assembly (10) continue to bore, thereby forming two hole positions on the same horizontal straight line of the cylinder body; S105: After confirming that the processing is correct, the operator uses the control panel (4) to release the clamping state of the double-cylinder clamping assembly (3), loosens the clamp, and removes the cylinder.
