Description

Technical Field

[0001] The invention relates to the technical field of numerically controlled machine tools, and in particular to a fixture oil supply structure and a horizontal machining workbench having the same. Background Art

[0002] With the rapid development of modern industry, CNC machine tools, as core equipment in the manufacturing industry, have a direct impact on production efficiency and product quality due to their performance and automation level. Horizontal machining center (HMC), as a high-performance CNC machine tool, is widely used in automobile manufacturing, aerospace, mold processing and other industries due to its unique advantages in processing complex parts and achieving high-precision requirements. A notable feature of the horizontal machining center is the automatic pallet changing system (APC), which can realize rapid conversion between multiple workbenches, thereby greatly improving the utilization rate of the machine and the flexibility of the production line.

[0003] However, during the operation of the horizontal machining center, the oil supply problem of the fixture has always been a key factor affecting its performance. The fixture is an important tool for fixing and positioning the workpiece, and its normal operation depends on a stable oil supply to achieve functions such as lubrication, clamping and cooling. In traditional horizontal machining centers, the oil supply is usually achieved through a quick-connect connector installed on the machine tool turntable or a multi-oil rotary joint connected to the top. However, these methods have many limitations:

[0004] Insufficient oil circuits: The number of oil circuits of quick-connect connectors is limited, which makes it difficult to meet the complex requirements of multiple stations and multiple oil circuits in high-precision machining.

[0005] Oil leakage from joints: Frequent rotation and movement lead to decreased sealing at the joints, and oil leakage often occurs, affecting the cleanliness of the machine tool and the working environment.

[0006] Expensive: In order to achieve multi-oil supply, multiple high-cost rotary joints are required, which increases the initial investment and subsequent maintenance costs of the equipment.

[0007] The rotary joint is seriously worn out during long-term use and is complicated to maintain, which reduces the reliability and service life of the machining center.

[0008] Therefore, in order to solve the problems of oil circuit restrictions, oil leakage, high cost and easy damage in the fixture oil supply of horizontal machining centers, finding a top oil inlet solution with stable structure, economical affordability and flexible operation has become a difficult problem that needs to be overcome urgently in the current field of CNC machine tool technology.

[0067] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0068] With the rapid development of modern industry, CNC machine tools, as core equipment in the manufacturing industry, have a direct impact on production efficiency and product quality through their performance and automation level. Horizontal machining center HMC, as a high-performance CNC machine tool, is widely used in automobile manufacturing, aerospace, mold processing and other industries due to its unique advantages in processing complex parts and achieving high-precision requirements. A notable feature of the horizontal machining center is that it has an automatic pallet exchange system APC, Automatic Pallet Changer, which can achieve rapid conversion between multiple workbenches, thereby greatly improving the utilization rate of the machine and the flexibility of the production line.

[0069] However, during the operation of the horizontal machining center, the oil supply problem of the fixture has always been a key factor affecting its performance. The fixture is an important tool for fixing and positioning the workpiece, and its normal operation depends on a stable oil supply to achieve functions such as lubrication, clamping and cooling. In traditional horizontal machining centers, the oil supply is usually achieved through a quick-connect connector installed on the machine tool turntable or a multi-oil rotary joint connected to the top. However, these methods have many limitations:

[0070] Insufficient oil circuits: The number of oil circuits of quick-connect connectors is limited, which makes it difficult to meet the complex requirements of multiple stations and multiple oil circuits in high-precision machining.

[0071] Oil leakage from joints: Frequent rotation and movement lead to decreased sealing at the joints, and oil leakage often occurs, affecting the cleanliness of the machine tool and the working environment.

[0072] Expensive: In order to achieve multi-oil supply, multiple high-cost rotary joints are required, which increases the initial investment and subsequent maintenance costs of the equipment.

[0073] The rotary joint is seriously worn out during long-term use and is complicated to maintain, which reduces the reliability and service life of the machining center.

[0074] Therefore, in order to solve the problems of oil circuit restrictions, oil leakage, high cost and easy damage in the fixture oil supply of horizontal machining centers, finding a top oil inlet solution with stable structure, economical affordability and flexible operation has become a difficult problem that needs to be overcome urgently in the current field of CNC machine tool technology.

[0075] Therefore, the technical purpose of the present application is to provide a fixture oil supply structure and a horizontal machining workbench having the same in order to solve the above problems.

[0076] First, the present application provides a clamp oil supply structure, the clamp oil supply structure comprising:

[0077] The exchange workbench body 1 includes an exchange door 101, and an oil separation component 102 is provided above the exchange door 101;

[0078] A crossbeam 2, the position of which can be adjusted on the exchange workbench body 1;

[0079] A first limiting assembly 3, at least part of which is disposed in the cross beam 2, an end of the first limiting assembly 3 away from the cross beam 2 passes through the cross beam 2 and is connected to the oil separation component 102, and an oil supply through hole 302 is disposed in the first limiting assembly 3;

[0080] The oil supply pipeline 4, at least part of which is arranged in the cross beam 2 to move with the cross beam 2, the oil outlet end of the oil supply pipeline 4 extends from the oil supply through hole 302 into the oil separation component 102 to divert the liquid output from the outlet end of the oil supply pipeline 4 to the two sides of the exchange gate 101 through the oil separation component 102.

[0081] Specifically, in this embodiment, Figure 1 As shown, the fixture oil supply mechanism provided by the present application includes an exchange workbench body 1, and the exchange workbench body 1 includes an exchange gate 101. An oil separation component 102 is provided above the exchange gate 101. The oil separation component 102 has a first oil outlet side and a second oil outlet side. The first oil outlet side and the second oil outlet side are respectively located on both sides of the exchange gate 101 to realize oil delivery to both sides of the exchange gate 101 respectively. The two sides of the exchange gate 101 have different areas for realizing different functions. A plurality of oil outlet holes are respectively provided on the first oil outlet side and the second oil outlet side. The oil delivered from the oil supply pipeline 4 enters the oil separation component 102, and then is separated by the oil separation component 102 and delivered to the two sides of the exchange gate 101 respectively. In a working area, a crossbeam 2 is provided on the exchange workbench body 1, and the position of the crossbeam 2 is adjustably set relative to the exchange workbench body 1. In the actual working process, the position of the crossbeam 2 can be rotated relative to the exchange workbench body 1, and a first limiting component 3 is provided in the crossbeam 2. The end of the first limiting component 3 away from the crossbeam 2 passes through the crossbeam 2 and is connected to the oil separation component 102. An oil supply through hole 302 is provided in the first limiting component 3, and one end of the oil supply pipeline 4 extends from the oil supply through hole 302 into the oil separation component 102 to transport oil to the oil separation component 102. At least a part of the other end of the oil supply pipeline 4 is arranged in the crossbeam 2 and is fixed to the crossbeam 2, and can move with the movement of the crossbeam 2.

[0082] By setting the oil distribution component 102 above the exchange gate 101, the oil circuit can be evenly distributed to the working areas on both sides of the exchange gate 101, ensuring the high efficiency and uniformity of the oil supply of the oil circuit, improving the lubrication and cooling effect of the fixture, and thus improving the processing accuracy and efficiency.

[0083] The connection design between the first limit assembly 3 and the crossbeam 2 and the existence of the internal oil supply through hole 302 allow the oil supply pipeline 4 to automatically turn with the rotation of the crossbeam 2, avoiding direct twisting and damage of the oil pipe and ensuring the continuity and stability of the oil circuit.

[0084] The oil supply pipeline 4 is partially arranged in the crossbeam 2 and fixed to the crossbeam 2, and can move stably with the movement of the crossbeam 2. This is particularly critical during the lifting and rotation of the exchange workbench body 1, ensuring that the oil circuit can still maintain normal oil supply under complex movements to avoid processing interruptions.

[0085] The position of the crossbeam 2 is adjustable relative to the exchange table body 1, so that the entire oil supply system can be flexibly adjusted according to actual needs, and the structure is compact and occupies little space, thereby improving the integration and space utilization of the equipment.

[0086] The present application reduces the need for expensive rotary joints through the pipe bending design, reduces the initial investment cost and subsequent maintenance cost of the equipment, and improves economic benefits.

[0087] Since most of the components of the oil supply system are fixedly connected to the exchange door 101 and the crossbeam 2, and mechanical wear is reduced by components such as self-lubricating bearing sleeves, the maintenance and debugging of the entire system become simpler and more convenient.

[0088] The fixture oil supply mechanism of the present application can adapt to the complex operating requirements of a multi-station horizontal machining center, provide stable oil supply to fixtures in different areas, and thus support high-precision and high-efficiency multi-station machining.

[0089] In summary, the fixture oil supply mechanism of the present application realizes efficient, stable and economical oil supply through optimized design, solves the key technical problems in the fixture oil supply of the horizontal machining center, and improves the performance and reliability of the machining center.

[0090] Furthermore, the cross beam 2 comprises: a shell 201, at least two baffles 202 are arranged in the shell 201, and the at least two baffles 202 are arranged along the extension direction of the shell 201;

[0091] A limiting space is formed between at least two baffles 202, and at least a portion of the first limiting component 3 is disposed in the limiting space.

[0092] Furthermore, the first limiting assembly 3 includes: a limiting member 301, and a limiting through hole 305 is provided on the limiting member 301;

[0093] The sleeve 303 is arranged at one end of the limit member 301, and the other end of the sleeve 303 passes through the cross beam 2 and is connected to the oil distribution component 102. The sleeve 303 has an accommodating through hole 304 for accommodating the oil supply pipeline 4, and the accommodating through hole 304 and the oil supply through hole 302 together form the oil supply through hole 302.

[0094] Specifically, Figures 1 to 12As shown, the cross beam 2 includes a shell 201, and at least two baffles 202 are arranged in the shell 201. In the present embodiment, the number of the baffles 202 is 4, and the 4 baffles 202 are arranged along the extension direction of the cross beam 2, wherein a limited space is formed between the two baffles 202 in the middle, and at least a part of the first limit assembly 3 is arranged in the limited space, and the first limit assembly 3 includes a limited member 301, and an oil supply through hole 302 is arranged on the limit member 301, and the other end of the limit member 301 is connected to a sleeve 303, and the other end of the sleeve 303 passes through the cross beam 2 and is connected to the oil separation component 102, and an accommodating through hole 304 for accommodating the oil supply pipeline 4 is provided in the sleeve 303, and the accommodating through hole 304 and the limiting through hole 305 together form the oil supply through hole 302, and one end of the oil supply pipeline 4 first passes through the limiting through hole 305, and then passes through the cross beam 2, and then penetrates into the oil separation component 102 from the accommodating through hole 304.

[0095] By setting at least two baffles 202 in the shell 201 of the beam 2, especially the four baffles in this embodiment, the interior of the beam 2 is reasonably divided to form a limiting space, which provides a stable installation environment for the first limiting component 3, avoids the disorderly movement of the oil supply pipeline 4 inside the beam 2, and improves the overall structural stability of the system.

[0096] The combination design of the stopper 301 and the sleeve 303 provides a precisely guided channel, namely, the oil supply through hole 302, for the oil supply pipeline 4. After passing through the stopper through hole 305, the oil supply pipeline 4 is connected to the oil distribution component 102 through the receiving through hole 304. This precise guidance ensures the accurate alignment of the oil supply pipeline 4, avoids the misalignment or damage of the oil supply pipeline 4 when the crossbeam 2 rotates, and ensures the continuity and reliability of the oil circuit.

[0097] The presence of the baffle 202 effectively avoids mechanical interference between the oil supply pipeline 4 and the inner wall of the beam 2 or other components when the beam 2 rotates, reduces wear and maintenance frequency, and extends the service life of the equipment.

[0098] The design of integrating the oil supply pipeline 4, the stopper 301 and the sleeve 303 into the crossbeam 2 not only makes the oil supply circuit more compact, but also reduces the impact of external environmental factors on the oil supply system, thereby improving the overall integration and space utilization of the system.

[0099] By separating the baffle 202 and fixing the limiter 301, the layout of the oil supply pipeline 4 in the crossbeam 2 is more orderly, reducing the oil circuit sealing problem caused by loose pipelines, improving the sealing performance of the oil circuit, and reducing the risk of oil leakage.

[0100] To summarize, the clamp oil supply mechanism of the present application realizes precise guidance and stable oil supply of the oil supply pipeline 4 by setting a baffle 202 and a first limit assembly 3 inside the crossbeam 2, reduces mechanical interference and maintenance costs, improves the sealing of the oil circuit and the system integration, and fully meets the needs of the horizontal machining center for clamp oil supply.

[0101] Furthermore, the limiting member 301 includes: a first limiting portion 3011, the first limiting portion 3011 is arranged obliquely relative to the horizontal plane, and the second limiting portion 3012 and the third limiting portion 3013 are arranged on both side edges of the first limiting portion 3011;

[0106] Among them, the first limiting section 3016 is arranged in an arc shape, and the opening of the first limiting section 3016 faces the second limiting section. The second limiting section is arranged in an arc shape, and the opening of the second limiting section faces the first limiting section 3016. The first limiting section 3016 and the second limiting section together form a limiting section.

[0107] Specifically, the limiting member 301 includes a first limiting portion 3011, the first limiting portion 3011 is inclined relative to the horizontal plane, and the second limiting portion 3012 and the third limiting portion 3013 are connected to the two sides of the first limiting portion 3011 respectively, the second limiting portion 3012 and the third limiting portion 3013 are arranged opposite to each other, and the two are parallel to each other. Holes for cable ties to pass through are respectively provided on the first limiting portion 3011, the second limiting portion 3012 and the third limiting portion 3013, so that at least a portion of the oil supply pipeline 4 is fixed to the limiting member 30 by the cable ties. 1, a fourth limiting portion 3014 is provided at one end of the second limiting portion 3012 away from the first limiting portion 3011, and the fourth limiting portion 3014 and the second limiting portion 3012 are arranged perpendicular to each other, and a fifth limiting portion 3015 is provided at one end of the third limiting portion 3013 away from the first limiting portion 3011, and the fifth limiting portion 3015 is arranged perpendicular to the third limiting portion 3013, wherein the limiting end of the fourth limiting portion 3014 and the limiting end of the fifth limiting portion 3015 are respectively facing each other, and the fourth limiting portion 3014 The limiting end and the limiting end of the fifth limiting portion 3015 together form a limiting division. One end of the oil supply pipeline 4 enters from the opening between the second limiting portion 3012 and the third limiting portion 3013, extends from the limiting division and penetrates into the oil supply through hole 302, extends from the sleeve 303 and is connected to the oil distribution component 102. A first limiting division 3016 is provided at one end of the fourth limiting portion 3014 relatively close to the fifth limiting portion 3015. The first limiting division 3016 is arranged in an arc shape. The fifth limiting portion is relatively close to the fourth limiting portion 3014. A second limiting division is provided at one end, and the second limiting division is also arranged in an arc shape. The shape and size of the second limiting division are consistent with the first limiting division. The opening of the first limiting division 3016 faces the second limiting division, and the opening of the second limiting division faces the first limiting division 3016. The first limiting division 3016 and the second limiting division jointly form a limiting division. Mounting holes 3017 are provided on the fourth limiting division 3014 and the fifth limiting division 3015, so that the limiting member 301 can be fixed to the top of the sleeve 303 through the mounting holes 3017.

[0108] The limiting member 301 includes a first limiting portion 3011, a second limiting portion 3012, a third limiting portion 3013, and a fourth limiting portion 3014 and a fifth limiting portion 3015 which are perpendicular to the second limiting portion 3012 and the third limiting portion 3013. The cooperation between these limiting portions and the oil supply pipeline 4 is fixed by cable ties, thereby ensuring the stability of the oil supply pipeline 4 in complex movements, reducing the jitter and displacement of the oil supply pipeline 4, and improving the accuracy and reliability of the oil supply.

[0109] The inclined setting of the first limiting portion 3011 and the arc-shaped design of the first limiting sub-portion 3016 and the second limiting sub-portion effectively reduce the friction and wear of the oil supply pipeline 4 during the rotation of the crossbeam, extend the service life of the oil supply pipeline 4, and reduce the maintenance cost.
