Description

Technical Field

[0001] This utility model relates to the field of lathe technology, and in particular to a horizontal machining center with quick tool change capability. Background Technology

[0002] A machining center is a highly automated CNC machining equipment. Its most prominent feature is its automatic tool changer, which allows it to automatically complete multiple machining operations such as milling, drilling, boring, and tapping in a single workpiece setup. These machines are typically equipped with a CNC system that controls the movement of the cutting tools and worktable through a program, resulting in high precision and stability, and enabling the machining of complex-shaped parts.

[0003] In existing technologies, conventional lathes require manual rotation of the tool holder during tool changing. When manually rotating the tool holder, uneven force or differences in operating habits can cause deviations in the angle and position of the tool after rotation. This may result in excessive perpendicularity between the step surface and the axis, making it difficult to guarantee the dimensional accuracy of the parts and reducing the precision of the products. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a horizontal machining center with quick tool changing capability.

[0005] This utility model is achieved by the following technical solution: a horizontal machining center machine tool with quick tool changing, including a horizontal machine tool, a tool changing assembly is provided on the top of the horizontal machine tool, a pull-back assembly is provided inside the tool changing assembly, and a replacement assembly is provided on the top of the tool changing assembly;

[0006] The tool changing assembly includes a base, a ratchet fixedly connected to the top of the base, a reverse ratchet engaged with the ratchet, a tool holder fixedly connected to the top of the reverse ratchet, a fixed rod fixedly connected to the bottom of the tool holder, a gear fixedly connected to the end of the fixed rod away from the tool holder, a gear engaged with the gear, a first fixed rod fixedly connected inside the gear, and a motor fixedly connected to the bottom end of the first fixed rod.

[0007] As a further improvement to the above solution, the fixing rod is slidably connected inside the base, the first fixing rod is rotatably connected inside the base, and the motor is fixedly connected to the bottom of the inner wall of the base.

[0008] With the above technical solution, when a tool change is required, the motor drives gear one to rotate via the first fixed rod. When gear one meshes with gear one, gear one drives the tool holder to rotate via the fixed rod. A reverse ratchet is fixed at the bottom of the tool holder and meshes with the ratchet. The ratchet is fixed to the base to ensure overall stability. When the reverse ratchet moves along the helical angle of the ratchet, it is affected by the helical teeth of the ratchet, causing the tool holder to drive gear one to rise via the fixed rod. Since gear one is thicker than gear one, it will not disengage from gear one when the gear rises. The gear meshing provides power for the rotation of the reverse ratchet, which allows for quick tool changes. The cooperation between the ratchet and the reverse ratchet ensures that the tool and the workpiece are at an accurate angle, improving the machining accuracy of the parts and reducing the product defect rate.

[0009] As a further improvement to the above solution, the pull-back assembly includes a rotating groove, which is formed inside the gear, and a rotating wheel is rotatably connected to the outer wall of the rotating groove.

[0010] As a further improvement to the above solution, a connecting rod is rotatably connected inside the rotating wheel, a limiting piece is fixedly connected to the end of the connecting rod away from the rotating wheel, and a spring is sleeved on the outer wall of the connecting rod.

[0011] As a further improvement to the above solution, a fixing plate is slidably connected to the outer wall of the connecting rod, and the fixing plate is fixedly connected to the inner wall of the base.

[0012] With the above technical solution, when the gear rises during tool change, the spring is compressed by the limiting plate and the fixing plate. At the same time, the elastic potential energy of the spring pushes the limiting plate, thereby ensuring that the reverse ratchet is always firmly engaged with the ratchet after rotation, ensuring that the reverse ratchet will not disengage from the ratchet, thus providing accurate reset, improving the product processing accuracy, reducing the defect rate, and reducing production costs.

[0013] As a further improvement to the above solution, the replacement component includes a slide groove, which is formed on the inner wall of the tool holder. A pressure plate is slidably connected to the outer wall of the slide groove, and a cutting blade is engaged with the pressure plate. A threaded rod is rotatably connected inside the pressure plate.

[0014] As a further improvement to the above solution, a handle is fixedly connected to the end of the threaded rod away from the pressure plate, and a support plate is threadedly connected to the threaded rod, with the support plate fixedly connected to the inner wall of the tool holder.

[0015] With the above technical solution, the operator rotates the threaded rod by turning the handle, so that the threaded rod is threadedly connected to the support plate and rotates inside the pressure plate. The pressure plate is engaged with the cutting blade. When the pressure plate slides along the groove, the cutting blade is released, and the cutting blade can be replaced, repaired or maintained at this time.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention utilizes a mechanism where, when a tool change is needed, the motor drives gear one to rotate via a first fixed rod. When gear one meshes with gear one, gear one drives the tool holder to rotate via the fixed rod. A reverse ratchet is fixed at the bottom of the tool holder and meshes with gear one. The ratchet is fixed to the base to ensure overall stability. As the reverse ratchet moves along the helical angle of the ratchet, it is affected by the helical teeth of the ratchet, causing the tool holder to rise via the fixed rod, driving gear one to move upward. Since gear one is thicker than gear one, it will not disengage from gear one while the gear one is rising. The meshing of gear one provides power for the rotation of the reverse ratchet, enabling rapid tool changes. The cooperation between the ratchet and the reverse ratchet ensures that the tool and the workpiece are at an accurate angle, improving the machining accuracy of parts and reducing the defect rate of products.

[0018] This invention achieves precise resetting by compressing the spring through the limiting plate and fixing plate when the gear rises during tool changing. Simultaneously, the elastic potential energy of the spring pushes the limiting plate, ensuring that the reverse ratchet remains firmly engaged with the ratchet after rotation, thus preventing the reverse ratchet from disengaging from the ratchet. This improves the precision of product processing, reduces the defect rate, and lowers production costs. Attached Figure Description

[0027] Example:

[0028] Please combine Figure 1-5 This embodiment provides a horizontal machining center machine tool with quick tool changing capability, including a horizontal machine tool 1, a tool changing assembly 2 on the top of the horizontal machine tool 1, a pull-back assembly 3 inside the tool changing assembly 2, and a replacement assembly 4 on the top of the tool changing assembly 2.

[0029] The tool changing assembly 2 includes a base 201, a ratchet 202 fixedly connected to the top of the base 201, a reverse ratchet 203 meshing with the ratchet 202, a tool holder 204 fixedly connected to the top of the reverse ratchet 203, a fixing rod 205 fixedly connected to the bottom of the tool holder 204, a gear 206 fixedly connected to the end of the fixing rod 205 away from the tool holder 204, a gear 207 meshing with the gear 206, a first fixing rod 208 fixedly connected inside the gear 207, and a motor 209 fixedly connected to the bottom of the first fixing rod 208.

[0030] The fixing rod 205 is slidably connected inside the base 201, the first fixing rod 208 is rotatably connected inside the base 201, and the motor 209 is fixedly connected to the bottom of the inner wall of the base 201.

[0031] The pullback assembly 3 includes a rotating groove 301, which is opened inside the gear 206, and a rotating wheel 302 is rotatably connected to the outer wall of the rotating groove 301.

[0032] A connecting rod 303 is rotatably connected inside the rotating wheel 302. A limit piece 304 is fixedly connected to the end of the connecting rod 303 away from the rotating wheel 302. A spring 305 is sleeved on the outer wall of the connecting rod 303.

[0033] A fixing plate 306 is slidably connected to the outer wall of the connecting rod 303, and the fixing plate 306 is fixedly connected to the inner wall of the base 201.

[0034] Replacement component 4 includes a slide 401, which is formed on the inner wall of the tool holder 204. A pressure plate 402 is slidably connected to the outer wall of the slide 401. A cutting blade 403 is engaged in the pressure plate 402. A threaded rod 404 is rotatably connected inside the pressure plate 402.

[0035] A handle 405 is fixedly connected to the end of the threaded rod 404 away from the pressure plate 402. A support plate 406 is threadedly connected to the threaded rod 404, and the support plate 406 is fixedly connected to the inner wall of the tool holder 204.

[0036] The implementation principle of a horizontal machining center with quick tool change capability in this embodiment is as follows: When a tool change is required, the motor 209 drives the gear 207 to rotate via the first fixed rod 208. When the gear 207 meshes with the gear 206, the gear 206 drives the tool holder 204 to rotate via the fixed rod 205, causing the tool holder 204 to rotate around the fixed rod 205. A reverse ratchet 203 is fixed at the bottom of the tool holder 204, and the reverse ratchet 203 meshes with the ratchet 202. At the same time, the ratchet 202 is fixed to the base 201, ensuring the overall stability. For stability, when the reverse ratchet 203 moves along the angle of the ratchet 202, it is affected by the helical teeth of the ratchet 202, causing the tool holder 204 to drive the gear 206 to rise via the fixed rod 205. Since the gear 207 is thicker than the gear 206, it will not disengage from the gear 207 while rising. Thus, the engagement of the gear 206 provides power for the rotation of the reverse ratchet 203, enabling rapid tool changing. The cooperation between the ratchet 202 and the reverse ratchet 203 ensures that the tool and the workpiece are at an accurate angle, improving the machining of parts. To improve precision and reduce product defect rates, a groove 301 is created inside the gear 206, while a rotating wheel 302 rotates on the outer wall of the groove 301. The wheel 302 rotates in conjunction with the connecting rod 303, and a spring 305 is sleeved on the outer wall of the connecting rod 303. The spring 305 slides between the connecting rod 303 and the fixed plate 306, and is fixed to the limiting plate 304. When the gear 206 rises during tool changing, the spring 305 is compressed by the limiting plate 304 and the fixed plate 306. Simultaneously, the elastic potential energy of the spring 305 pushes the limiting plate 304, thereby ensuring that the reverse ratchet 203 completes its rotation. After completion, it is always firmly engaged with the ratchet 202 to ensure that the reverse ratchet 203 will not disengage from the ratchet 202, thereby providing precise reset, improving the product processing accuracy, reducing the defect rate, and reducing production costs. The operator drives the threaded rod 404 to rotate through the handle 405, so that the threaded rod 404 is threadedly connected to the support plate 406 and rotates inside the pressure plate 402. The pressure plate 402 is engaged with the cutting blade 403. When the pressure plate 402 slides along the slide groove 401, the cutting blade 403 is released, and the cutting blade 403 can be replaced, repaired, or maintained at this time.
