Description

Technical Field

[0001] This utility model belongs to the field of milling head processing technology, specifically relating to a right-angle milling head structure with shock absorption function. Background Technology

[0002] A right-angle milling head, also known as a transverse milling head or horizontal milling head, is characterized by its tool output axis being parallel to the horizontal plane. This unique design allows for the conversion between vertical and horizontal operation in a machining center, and it is primarily used for side machining of workpieces.

[0003] Chinese patent CN214770674U discloses a horizontal boring and milling head. The specification shows that by setting rubber damping pads and damping springs, the rubber damping pads are fixedly installed on the left and right sides of the boring and milling head body, and the damping springs are installed at the bottom of the boring and milling head body. The rubber damping pads and damping springs can effectively dampen and buffer the boring and milling head body during use, reduce the vibration generated during operation, and thus avoid damage to the boring and milling head body due to long-term working vibration.

[0004] In the aforementioned application, damping springs are installed at the bottom of the boring and milling head body for damping. Due to the elasticity of the springs themselves, when the boring and milling head experiences initial vibration due to cutting force, the springs undergo elastic deformation at the moment of force application. As the boring and milling head vibrates, the springs are continuously compressed and stretched, making the vibration of the boring and milling head more intense. Utility Model Content

[0005] The purpose of this invention is to provide a right-angle milling head structure with shock absorption function to solve the problem that existing milling head devices are prone to vibration during processing.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0008] Preferably, the auxiliary mechanism includes two uprights fixedly connected to the end face of the mounting plate, each upright has a support rod fixedly connected to its arc surface, and each support rod has a baffle fixedly connected to its end away from the upright.

[0009] Preferably: a gear is fixedly connected to the arc surface of one of the uprights; a fixing sleeve and a rectangular frame are fixedly connected to the end face of the mounting plate; an L-shaped rod is slidably connected inside the fixing sleeve; a rack is fixedly connected to one end of the L-shaped rod; a round rod is fixedly connected to one end of the rack; a rectangular plate is fixedly connected to the end of the round rod away from the rack; an airbag cushion is provided on the inner wall of the rectangular frame; and a conduit is connected to the surface of the airbag cushion.

[0010] Preferably, the tooth surface of the rack meshes with the tooth surface of the gear, and the end of the conduit away from the airbag cushion passes through the rectangular frame.

[0011] Preferably, the end of the rectangular frame away from the airbag cushion is connected to a diffusion hood, and the cross-sectional shape of the diffusion hood is trapezoidal.

[0012] Preferably, the size of the rectangular plate is smaller than the size of the inner wall of the rectangular frame, and the conduit is a flexible tube.

[0013] Preferably, the end face of the mounting plate is fixedly connected to two upright blocks, and the surface of the upright blocks is slidably inserted with insert rods. The arc surface of the uprights is provided with multiple insertion holes that are adapted to the insert rods.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model can reduce the vibration generated by the shell during operation by using the damping between the sleeve and the slide rod and the elastic force of the spring, thus achieving the effect of shock absorption. By using the baffle, it can block the chips generated by the workpiece and minimize the occurrence of chip splashing. By adjusting the position of the baffle, the baffle can be brought closer to the workpiece, thereby improving the chip blocking effect.

[0016] 2. This utility model can compress the airbag cushion through gear and rack transmission, and use the airflow discharged from the airbag cushion to blow away the debris falling on the surface of the mounting plate. When the receiving baffle is adjusted to move away from the workpiece, the airflow discharged from the airbag cushion can blow away the debris on the surface of the mounting plate.

[0024] In this embodiment, the housing 1 is an existing device and will not be described in detail here. The sleeve 3 and the slide rod 4 together form a damper, which is also an existing device. Its cooperation with the spring 5 can reduce the vibration generated by the housing 1.

[0026] It should be noted that the baffle 603 has an arc-shaped cross-section, which serves to block the debris generated during the processing of the workpiece in the housing 1.

[0027] In an optional embodiment: a gear 604 is fixedly connected to the arc surface of one of the uprights 601; a fixing sleeve 607 and a rectangular frame 609 are fixedly connected to the end face of the mounting plate 2; an L-shaped rod 606 is slidably connected inside the fixing sleeve 607; a rack 605 is fixedly connected to one end of the L-shaped rod 606; a round rod 6051 is fixedly connected to one end of the rack 605; a rectangular plate 608 is fixedly connected to the end of the round rod 6051 away from the rack 605; and an airbag cushion 610 is provided on the inner wall of the rectangular frame 609, with a conduit 611 communicating with the surface of the airbag cushion 610.

[0028] It should be noted that the size of the rectangular plate 608 is smaller than the size of the inner wall of the rectangular frame 609. The airbag 610 is made of elastic material and has an internal cavity. When it is squeezed, the internal air will be expelled. When it is not squeezed, it will return to its expanded state according to its own elasticity and re-inhale air.

[0029] In an optional embodiment: the tooth surface of rack 605 meshes with the tooth surface of gear 604, and the end of conduit 611 away from airbag cushion 610 passes through rectangular frame 609.

[0030] It should be noted that the conduit 611 is a flexible tube with good plasticity, and it is not easy to restore its original shape after deformation.

[0031] In an optional embodiment: the end of the rectangular frame 609 away from the airbag cushion 610 is connected to a diffuser 612, the diffuser 612 having a trapezoidal cross-sectional shape.

[0035] The working principle of this utility model is as follows: During use, the housing 1 processes the workpiece. Due to the damping between the sleeve 3 and the slide rod 4, the vibration generated by the working of the housing 1 can be reduced by the sliding of the sleeve 3 and the slide rod 4 and the elastic force of the spring 5. Before processing, the upright rod 601 is rotated. The rotation of the upright rod 601 will adjust the angle of the baffle 603, so that the baffle 603 is close enough to the workpiece. After adjustment, the upright block 613 is pushed and inserted into the corresponding insertion hole 615 to realize the upright rod 60 The stability of the baffle 603 ensures that the debris generated during the processing of the workpiece is blocked by the baffle 603 when it splashes. When not in use, the baffle 603 is moved away from the workpiece, and the upright rod 601 is rotated in the opposite direction. The gear 604 drives the rack 605 to move, and the rectangular plate 608 moves towards the airbag 610 until it is squeezed. The airbag 610 is made of elastic material and has a cavity inside. When squeezed, the internal air is discharged from the conduit 611 and blown towards the surface of the mounting plate 2, blowing away the debris that splashes on the surface of the mounting plate 2.
