[0002] A milling machine is a machine tool that uses a milling cutter to machine workpieces. It is mainly used for operations such as milling, drilling, and boring. The milling machine achieves machining by using the rotational motion of the milling cutter as the primary motion, while simultaneously utilizing the feed motion of the worktable or milling head.

[0003] Currently, existing milling machines cannot effectively clamp cylinder heads of different sizes when processing them because they lack a proper external clamping mechanism. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing models, which lack a well-designed moving clamping mechanism, cannot effectively clamp cylinder heads of different sizes, and to propose a milling machine for machining automobile engine cylinder heads.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A milling machine for machining automobile engine cylinder heads includes a base and a machine body. The machine body is located on top of the base and includes a clamping mechanism. The clamping mechanism includes a placement plate, which is located on one side of the machine body. The top of the placement plate has two first sliding grooves. A lead screw is rotatably inserted between the inner walls of the two ends of the first sliding grooves. A slider is threaded onto the outer wall of the lead screw and slides within the first sliding grooves. A second sliding groove is located on one side of the slider, and two clamping plates are slidably connected within the second sliding groove. A toothed rack is fixedly connected to one side of the clamping plates. A connecting rod is rotatably inserted into one side of the slider. A gear is keyed to one end of the connecting rod, and the gear meshes with the toothed rack. A second handle is fixedly connected to the other end of the connecting rod, and a locking mechanism is also provided at one end of the connecting rod.

[0007] Furthermore, the locking mechanism includes a sliding sleeve that is slidably fitted onto one end of a connecting rod. The outer circumferential wall of one end of the connecting rod is integrally formed with multiple limiting blocks. The inner circumferential wall of the sliding sleeve is provided with multiple third sliding grooves, in which the limiting blocks slide. Multiple locking blocks are welded to one end of the sliding sleeve.

[0008] Furthermore, one side of the slider is provided with multiple slots, and the locking block engages with the slots.

[0009] Furthermore, a rotating rod is rotatably connected to one side of the machine body, and a control panel is fixedly connected to one end of the rotating rod.

[0010] Furthermore, a motor is fixedly connected to the top of one side of the machine body, and a drill bit is keyed to the output end of the motor.

[0011] Furthermore, a first handle is fixedly connected to the outer wall of the lead screw, and the outer wall of the first handle is provided with an anti-slip groove.

[0012] Furthermore, a rubber pad is adhered to one side of the clamp.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By turning the lead screw, the slider moves within the first groove, thereby moving the clamping plate and adjusting the distance between the two sets of clamping plates. Then, turning the second handle rotates the connecting rod, which in turn rotates the gear. Under the meshing action of the gear and the toothed rack, the two clamping plates converge towards the center, thus clamping the cylinder head to accommodate different sizes of cylinder heads.

[0015] 2. By pushing the sliding sleeve inward, the limiting block moves within the third sliding groove, thereby engaging the locking block with the locking groove, thus fixing the connecting rod and fixing the gear's position, thereby maintaining the clamping state of the cylinder head and preventing the cylinder head from loosening.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-4 A milling machine for machining automobile engine cylinder heads includes a base 1 and a machine body 2. The machine body 2 is located on top of the base 1 and includes a clamping mechanism. The clamping mechanism includes a placement plate 9, which is located on one side of the machine body 2. The top of the placement plate 9 is provided with two first slide grooves 10. A lead screw 11 is rotatably inserted between the inner walls of the two ends of the first slide groove 10. A slider 12 is threaded onto the outer wall of the lead screw 11. The slider 12 slides within the first slide groove 10. A first handle 1101 is fixed to the outer wall of the lead screw 11 by bolts. Tightening the first handle 1101 causes the slider 12 to move within the first slide groove 10, thereby moving the clamping plate 14 to accommodate different specifications of cylinder heads.

[0023] A second groove 13 is provided on one side of the slider 12. Two clamping plates 14 are slidably connected in the second groove 13. A toothed rack 15 is fixed to one side of the clamping plate 14 by bolts. A connecting rod 18 is rotatably inserted into one side of the slider 12. A gear 16 is keyed to one end of the connecting rod 18. The gear 16 meshes with the toothed rack 15. A second handle 21 is fixed to the other end of the connecting rod 18 by bolts. Turning the second handle 21 drives the connecting rod 18 to rotate, thereby driving the gear 16 to rotate. Under the action of the gear 16 meshing with the toothed rack 15, the two clamping plates 14 are brought together in the middle, thereby clamping the cylinder head.

[0024] A locking mechanism is also provided at one end of the connecting rod 18. The locking mechanism includes a sliding sleeve 19, which is slidably sleeved on one end of the connecting rod 18. Multiple limiting blocks 1801 are integrally formed on the outer circumference of one end of the connecting rod 18. Multiple third sliding grooves 20 are provided on the inner circumference of the sliding sleeve 19. The limiting blocks 1801 slide in the third sliding grooves 20. Multiple locking blocks 1701 are welded to one end of the sliding sleeve 19. Multiple locking slots 17 are provided on one side of the slider 12. The locking blocks 1701 engage with the locking slots 17. Pushing the sliding sleeve 19 inward causes the limiting blocks 1801 to move in the third sliding grooves 20, thereby engaging the locking blocks 1701 with the locking slots 17, thus fixing the connecting rod 18, thereby fixing the state of the gear 16, and thus maintaining the clamping state of the cylinder head.

[0025] A rotating rod 5 is rotatably connected to one side of the machine body 2. One end of the rotating rod 5 is fixed to a control panel 6 by bolts, which facilitates the unfolding and storage of the control panel 6. A motor 7 is fixed to the top of one side of the machine body 2 by bolts. A drill bit 8 is connected to the output end of the motor 7. The drill bit 8 is rotated by the motor 7 to process the cylinder head. The outer wall of the first handle 1101 is provided with anti-slip grooves, which facilitates the operation of the first handle 1101. A rubber pad 1401 is glued to one side of the clamping plate 14, which increases the friction between the clamping plate 14 and the cylinder head and improves the stability of the cylinder head clamping.

[0026] An electric push rod is bolted to the top of the base 1. A slide block is bolted to the top of the electric push rod, and the slide block slides up and down on one side of the machine body 2. The electric push rod drives the slide block to move up and down, thereby driving the cylinder head to move up and down so that the drill bit 8 can contact the cylinder head. The placement plate 9 slides on the slide block. A threaded rod is rotatably inserted between the two sides of the slide block. A handle is welded to one end of the threaded rod. A sliding block is threaded onto the outer wall of the threaded rod. A sliding hole is provided on the top of the slide block. The sliding block slides in the sliding hole. The top of the sliding block is fixedly connected to the bottom of the placement plate 9. Turning the handle drives the threaded rod to rotate, thereby driving the placement plate 9 to move back and forth, thus adjusting the processing position.

[0027] The working principle of this embodiment is as follows: In use, firstly, turn the two first handles 1101 to move the two sliders 12 in the two first slide grooves 10, thereby moving the clamping plate 14 and adjusting the distance between the clamping plates 14 of the two sliders 12 to accommodate cylinder heads of different specifications. Then, place the cylinder head on the clamping plate 14 at the bottom of the two sliders 12. Next, turn the second handle 21 to rotate the connecting rod 18, thereby rotating the gear 16. Under the action of the gear 16 meshing with the toothed rack 15, the two clamping plates 14 converge towards the middle, thereby clamping the cylinder head. Then, push the sliding sleeve 19 inward to move the limiting block 1801 in the third slide groove 20, thereby engaging the locking block 1701 with the locking groove 17, thereby fixing the connecting rod 18 and fixing the state of the gear 16. Then, use the motor 7 to drive the drill bit 8 to rotate, thereby processing the cylinder head.
