Description

Technical Field

[0001] This application relates to the technical field of drilling equipment, and in particular to a drilling machine. Background Technology

[0002] Currently, punching machines are commonly used punching equipment in the machining field, widely used for batch punching operations on workpieces such as sheet metal, profiles, pipes, and leather. Multi-station punching machines, with their multiple synchronous punching structures, can simultaneously complete multiple punching operations on workpieces, significantly improving processing efficiency and are widely used in large-scale production scenarios.

[0003] Most multi-station punching machines on the market currently use a single-sided adjustment structure for the sliding seat equipped with the punch rod, achieving translational positioning of the sliding seat only through a single set of adjustment rods. This structure has significant drawbacks in actual use: uneven force distribution during single-sided adjustment, the sliding seat is prone to tilting and jamming during sliding adjustment, resulting in poor sliding smoothness. Long-term use will lead to wear and displacement of the sliding seat and punch rod, directly affecting the punching position accuracy and causing problems such as workpiece punching deviation and scrap. Utility Model Content

[0004] This application provides a punching machine that can achieve synchronous adjustment on both sides, greatly improving the stability and smoothness of adjustment, accurately controlling the punching position, ensuring the consistency of multi-station processing, and improving the reliability of equipment operation.

[0005] The drilling machine provided in this application adopts the following technical solution: A punching machine includes a base with a plurality of sliding seats arranged at intervals on the base. A punching assembly is mounted on the base, and the punching assembly includes a plurality of punch rods passing through the sliding seats. The punch rods move synchronously with their respective sliding seats. A first adjustment mechanism and a second adjustment mechanism are rotatably disposed on the base for adjusting the intervals between the sliding seats. The sliding of the sliding seats is controlled by the first adjustment mechanism and the second adjustment mechanism. A linkage mechanism is provided between the first adjustment mechanism and the second adjustment mechanism for driving the first adjustment mechanism and the second adjustment mechanism to rotate synchronously.

[0006] Preferably, the first adjustment mechanism includes a first drive rod, and the sliding seats are sequentially disposed outside the first drive rod, with a portion of the sliding seats being threadedly connected to the first drive rod.

[0007] Preferably, the first adjustment mechanism further includes a second drive rod, and the sliding seats are sequentially disposed outside the second drive rod, with the remaining sliding seats threadedly connected to the second drive rod.

[0008] Preferably, the first drive rod is provided with a first driving gear, and the second drive rod is provided with a first driven gear; the first driving gear and the first driven gear mesh with each other to drive the first drive rod and the second drive rod to rotate synchronously.

[0009] Preferably, the second adjustment mechanism includes a third drive rod, and the sliding seat is sequentially disposed outside the third drive rod, with a portion of the sliding seat being threadedly connected to the third drive rod.

[0010] Preferably, the second adjustment mechanism further includes a fourth drive rod, with the sliding seats sequentially passing through the outside of the fourth drive rod, and the remaining sliding seats being threadedly connected to the fourth drive rod.

[0011] Preferably, the linkage mechanism includes a main sprocket rotatably mounted on the base, a first driven sprocket mounted on the second drive rod, and a second driven sprocket mounted on the third drive rod; the main sprocket and the first driven sprocket are connected by a first chain to form a chain drive connection; the main sprocket and the second driven sprocket are connected by a second chain to form a chain drive connection.

[0012] Preferably, the third drive rod is provided with a second driving gear, and the fourth drive rod is provided with a second driven gear; the second driving gear and the second driven gear mesh with each other to drive the third drive rod and the fourth drive rod to rotate synchronously.

[0013] Preferably, the base is provided with a guide plate, the sliding seat is slidably disposed on the guide plate, a locking rod is rotatably disposed on the guide plate, and one side of the locking rod forms a contact surface for abutting against the sliding seat; the base is also provided with a driving member for driving the locking rod to rotate.

[0014] In summary, this application includes at least one of the following beneficial technical effects: The linkage mechanism enables the synchronous rotation of the first and second adjustment mechanisms, ensuring that the upper and lower sides of the sliding seat are evenly stressed and move synchronously. This greatly improves the problems of easy tilting, jamming, and offset of the sliding seat caused by traditional single-sided adjustment, making the position adjustment of the sliding seat smoother and more stable, effectively reducing the probability of mechanical jamming and component wear, and extending the service life of the equipment. Through the synchronized first and second adjustment mechanisms, the sliding position and spacing of each set of sliding seats can be uniformly controlled, realizing the synchronous and precise adjustment of the punching position of multiple sets of punch rods. The sliding displacement error of each station is small, which improves the problem of poor synchronization of multiple stations and large punching position deviation of traditional equipment, greatly improves the dimensional accuracy and uniformity of workpiece punching, effectively reduces the workpiece scrap rate, and adapts to the needs of high-precision batch punching processing. The integrated synchronous adjustment achieved through a linkage mechanism eliminates the need for individual fine-tuning of each sliding seat, significantly simplifying the equipment adjustment process, shortening the time required to adjust the station spacing, and improving production debugging efficiency. Furthermore, the sliding seat interval can be flexibly adjusted according to workpiece specifications, adapting to multi-station punching operations for workpieces of different sizes, thus significantly enhancing the equipment's versatility and practicality.

[0017] The present application will be further described in detail below with reference to the accompanying drawings.

[0018] This application discloses a punching machine.

[0019] Reference Figure 1 , Figure 2The punching machine includes a base 1, on which a plurality of sliding seats 2 are arranged at intervals along the horizontal direction. This embodiment uses seven sets of sliding seats 2 as an example. For ease of understanding, the sliding seats 2 will be numbered sequentially as: first, second, third, fourth, fifth, sixth, and seventh sliding seats 2. A punching assembly 3 is mounted on the top of the base 1. The punching assembly 3 includes punch rods 30 in a number corresponding to the number of sliding seats 2. The punch rods 30 are vertically inserted and confined within the perforations on the top of their respective sliding seats 2. The punching assembly 3 also includes a hydraulic cylinder fixedly installed on the top of the base 1. The piston rod of the hydraulic cylinder is used to drive the punch rods 30 to rise and fall synchronously. The punching process is completed by the synchronous downward pressing of the punch rods 30.

[0020] like Figure 2 , Figure 3 As shown, the upper end of the punch 30 is slidably limited on the machine base 1, and the lower end of the punch 30 is limited on its respective corresponding sliding seat 2. The first, second, third, fifth, sixth, and seventh sliding seats 2 can all be slidably mounted on the machine base 1 in the horizontal direction. As the sliding seats 2 move, the punch 30 will move synchronously with its respective sliding seat 2. By adjusting the spacing between each set of sliding seats 2, the spacing of the punch 30 can be synchronously adjusted.

[0021] like Figure 3 , Figure 4 As shown, a first adjusting mechanism 4 and a second adjusting mechanism 5 for adjusting the spacing of each sliding seat 2 are rotatably mounted on the base 1. The first adjusting mechanism 4 and the second adjusting mechanism 5 are located on the upper and lower sides of the sliding seat 2, respectively. The sliding of the sliding seat 2 is controlled by the first adjusting mechanism 4 and the second adjusting mechanism 5. The first adjusting mechanism 4 located on the upper side of the sliding seat 2 includes a first driving rod 40, the length of which extends along the placement direction of each group of sliding seats 2. Each group of sliding seats 2 is sequentially inserted through the outside of the first driving rod 40. The first, third, fifth, and seventh sliding seats 2 are threadedly connected to the corresponding external threaded section on the first driving rod 40 through an internal threaded sleeve 20. The second and sixth sliding seats 2 are slidably inserted through the outside of the first driving rod 40.

[0022] The internal threaded sleeves 20 of the first and seventh sliding seats 2 are of the same specification and have opposite threads. When the first drive rod 40 rotates, the first and seventh sliding seats 2 will move synchronously in a direction that moves closer to or further away from each other. The internal threaded sleeves 20 of the third and fifth sliding seats 2 are of the same specification and have opposite threads. When the first drive rod 40 rotates, the third and fifth sliding seats 2 will move synchronously in a direction that moves closer to or further away from each other.

[0023] like Figure 4 , Figure 5As shown, the fourth sliding seat 2, located at the center, is rotatably mounted on the first drive rod 40 via a bearing. When the first drive rod 40 rotates, the fourth sliding seat 2 will rotate relative to the first drive rod 40, thus keeping the fourth sliding seat 2 stationary. It should be noted that in this embodiment, the internal threaded sleeve 20 of the first and seventh sliding seats 2 is M24×3, and the internal threaded sleeve 20 of the third and fifth sliding seats 2 is M18×1.

[0024] like Figure 4 , Figure 5 As shown, the first adjusting mechanism 4 also includes a second driving rod 41 parallel to the first driving rod 40, which is rotatably mounted on the base 1. Sliding seats 2 are sequentially inserted through the outside of the second driving rod 41. The second and sixth sliding seats 2 are threadedly connected to the corresponding external threaded sections on the second driving rod 41 via internal threaded sleeves 20. The first, third, fourth, fifth, and seventh sliding seats 2 are all slidably inserted through the outside of the first driving rod 40. The internal threaded sleeves 20 on the second and sixth sliding seats 2 are of the same specification and have opposite threads. When the second driving rod 41 rotates, the second and sixth sliding seats 2 will move synchronously towards or away from each other. In this embodiment, the internal threaded sleeves 20 of the second and sixth sliding seats 2 are M18×1.

[0025] like Figure 6 , Figure 7 As shown, a handwheel 400 is coaxially fixed to one end of the first drive rod 40, allowing the user to drive the first drive rod 40 to rotate. A first driving gear 42 is coaxially fixed to the other end of the first drive rod 40, and a first driven gear 43, meshing with the first driving gear 42, is coaxially fixed to the second drive rod 41. When the first drive rod 40 rotates, the meshing of the first driving gear 42 and the first driven gear 43 causes the second drive rod 41 to rotate synchronously in the opposite direction. This allows for free adjustment of the spacing between the punches 30 on each set of sliding seats 2. The first drive rod 40 can also be controlled to rotate by a motor mounted on the base 1. A motor gear 13, meshing with the first driving gear 42, is mounted on the motor's output shaft. The rotation of the motor gear 13 controls the synchronous rotation of the first drive rod 40.

[0026] like Figure 5 , Figure 6 as well as Figure 7As shown, the second adjustment mechanism 5 located below the sliding seat 2 includes a third drive rod 50, the length of which extends along the placement direction of each set of sliding seats 2. Each set of sliding seats 2 is sequentially inserted through the outside of the third drive rod 50, wherein the second and sixth sliding seats 2 are also threadedly connected to the corresponding external thread section of the third drive rod 50 through internal threaded sleeves 20. The internal threaded sleeves 20 on the second and sixth sliding seats 2 that are threaded to the third drive rod 50 are of the same specification and have opposite threads. In this embodiment, the specification of the internal threaded sleeves 20 on the second and sixth sliding seats 2 is M18×2.

[0027] like Figure 5 , Figure 6 as well as Figure 7 As shown, the second adjustment mechanism 5 also includes a fourth drive rod 51. The first, third, fifth, and seventh sliding seats 2 are threadedly connected to the corresponding external threaded sections of the fourth drive rod 51 via internal threaded sleeves 20. The second and fourth sliding seats 2 are slidably disposed on the outside of the fourth drive rod 51. The assembly method and adjustment principle of the first, third, fifth, and seventh sliding seats 2 on the fourth drive rod 51 are the same as those on the first drive rod 40, and will not be described again here.

[0028] like Figure 5 , Figure 6 As shown, a linkage mechanism 6 is provided between the first adjusting mechanism 4 and the second adjusting mechanism 5. The linkage mechanism 6 is used to drive the first adjusting mechanism 4 and the second adjusting mechanism 5 to rotate synchronously. The linkage mechanism 6 includes a main sprocket 60 rotatably mounted on the base 1, a first driven sprocket 61 coaxially fixed to the end of the second drive rod 41, and a second driven sprocket 62 coaxially fixed to the end of the third drive rod 50. The main sprocket 60 and the first driven sprocket 61 are connected by a first chain 63, and the main sprocket 60 and the second driven sprocket 62 are connected by a second chain 64.

[0029] like Figure 5 , Figure 6 As shown, a second driving gear 7 is coaxially fixed to the end of the third drive rod 50 away from the second driven sprocket 62, and a second driven gear 8 is coaxially fixed to the fourth drive rod 51. The second driving gear 7 and the second driven gear 8 mesh with each other to drive the third drive rod 50 and the fourth drive rod 51 to rotate synchronously in opposite directions. When the first drive rod 40 rotates, the fourth drive rod 51 rotates in the same direction as the first drive rod 40, while the second drive rod 41 rotates in the same direction as the third drive rod 50. The rotation directions of the fourth drive rod 51 and the first drive rod 40 are opposite to the rotation directions of the second drive rod 41 and the third drive rod 50.

[0030] like Figure 6 , Figure 7as well as Figure 8 As shown, a guide plate 10 located below the sliding seats 2 is fixedly installed on the base 1, and each set of sliding seats 2 slides through the guide plate 10. A locking rod 11 is rotatably installed on the guide plate 10, and the length of the locking rod 11 extends along the placement direction of each set of sliding seats 2. One side of the locking rod 11 is eccentrically formed with a contact surface 12 for abutting against each set of sliding seats 2. The base 1 is also provided with a driving member 9 for driving the locking rod 11 to rotate. In this embodiment, the driving member 9 is a cylinder. The piston rod of the cylinder is linked to the locking rod 11 through multiple sets of connecting rods. When the piston rod of the driving member 9 drives the locking rod 11 to rotate until the contact surface 12 abuts against each set of sliding seats 2, the locking rod 11 locks each set of sliding seats 2 under the contact of the contact surface 12, thereby ensuring the stability of each set of sliding seats 2 during punching. When it is necessary to adjust the spacing between each group of sliding seats 2, the control drive 9 drives the locking rod 11 to rotate in the opposite direction, so that the contact surface 12 is separated from each group of sliding seats 2, and the locking of the sliding seats 2 can be released.

[0031] The implementation principle is as follows: A first adjustment mechanism 4 and a second adjustment mechanism 5 are respectively set on the upper and lower sides of the sliding seat 2. The spacing of each group of sliding seats 2 is controlled by adjusting both sides. At the same time, the linkage mechanism 6 is used to realize the synchronous rotation of the first adjustment mechanism 4 and the second adjustment mechanism 5, so that the upper and lower sides of the sliding seat 2 are evenly stressed and move synchronously. This greatly improves the problems of easy tilting, jamming and offset of the sliding seat 2 caused by traditional single-sided adjustment, making the position adjustment of the sliding seat 2 smoother and more stable, effectively reducing the probability of mechanical jamming and component wear, and extending the service life of the equipment.

[0032] Through the synchronized first adjustment mechanism 4 and the second adjustment mechanism 5, the sliding position and spacing of each group of sliding seats 2 can be uniformly controlled, realizing the synchronous and precise adjustment of the punching position of multiple groups of punch rods 30. The sliding displacement error of each station is small, which improves the problem of poor synchronization of multiple stations and large punching position deviation of traditional equipment, greatly improves the dimensional accuracy and uniformity of workpiece punching, effectively reduces the workpiece scrap rate, and adapts to the needs of high-precision batch punching processing.

[0033] Each set of sliding seats 2, through a double-sided threaded engagement structure, can form a bidirectional limiting and fixing mechanism for the sliding seats 2. After adjustment, there is no risk of loosening or displacement of the sliding seats 2, resulting in greater stability during the punching operation of the equipment and avoiding punching failures caused by displacement deviation of the sliding seats 2, thus reducing the equipment failure rate. The piston rod of the driving component 9 drives the locking rod 11 to rotate until the contact surface 12 abuts against each set of sliding seats 2. Under the contact of the contact surface 12, the locking rod 11 locks each set of sliding seats 2, thereby further ensuring the stability of each set of sliding seats 2 during punching.

[0034] The integrated synchronous adjustment is achieved through the linkage mechanism 6, eliminating the need for separate fine-tuning of individual sliding seats 2. This significantly simplifies the equipment adjustment process, shortens the time required to adjust the station spacing, and improves production debugging efficiency. Furthermore, the spacing of the sliding seats 2 can be flexibly adjusted according to workpiece specifications, adapting to multi-station punching operations for workpieces of different sizes, thus significantly enhancing the equipment's versatility and practicality.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
