Description

Technical Field

[0001] This utility model relates to the field of rotary shaft machining technology, specifically a rotary shaft machining ejector device. Background Technology

[0002] In rotary machining on a CNC engraving machine, the rotating device is fixed at only two ends. If the cylindrical material being processed is too long, too small in diameter, or too heavy, the middle part of the material will sag. This results in the depth of cut being too small in the middle or too large at both ends, causing the material to be misshapen. In plasma rotary machining, only the two ends are fixed. In addition to the above problems, the cylindrical tube being processed can only be engraved, not cut. Cutting steel is also quite troublesome, causing inconvenience to customers and creating significant problems for their production and processing.

[0003] According to a public notice (Announcement No.: CN208644690U) of a rotary shaft machining top-feeding device, the above application adds a top-feeding frame, bullseye wheel, top-feeding slide plate, lead screw drive nut, lead screw, and flange. This design is convenient to use, simple in structure, easy to install and adjust, easy to support, and has good performance. It solves the problem that in the rotary shaft machining of engraving machines, the rotary device is only fixed at both ends. Due to the cylindrical material being processed being too long, too small in diameter, or too heavy, the middle part of the material will sag, resulting in the depth of cut being too small in the middle part of the workpiece or too large at both ends, causing the machining to be deformed. In plasma rotary machining, only both ends are fixed. In addition to the above problems, the processed round tube can only be engraved, not cut. Cutting steel is also relatively troublesome, which brings inconvenience to customers and causes great trouble to their production and processing.

[0004] However, the diameter of the rotating shaft varies, and the spacing of the V-shaped top support is relatively limited, so it can only be used for rotating shafts with a specific diameter range. For rotating shafts with excessively large or small diameters, the V-shaped top support cannot provide effective support. Utility Model Content

[0005] The purpose of this invention is to provide a rotary shaft machining ejector device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rotary shaft machining ejector device, comprising an ejector slide plate, a through hole on the surface of the ejector slide plate, a lead screw threadedly connected to the through hole, a mounting plate rotatably connected to the top end of the lead screw, a handwheel fixedly connected to the bottom end of the lead screw, an adjustment component on the surface of the mounting plate, the adjustment component comprising a groove, the groove being formed on the surface of the mounting plate, two sets of symmetrically arranged sliders slidably connected inside the groove, the two sets of sliders being threadedly connected by a bidirectional threaded rod, the bidirectional threaded rod penetrating and rotatably connected to the side wall of the mounting plate, a rotating wheel fixedly connected to the end of the bidirectional threaded rod, and an inclined plate fixedly connected to the surface of the slider.

[0007] A cleaning component is provided on the surface of the mounting plate. The cleaning component includes a positioning rod that passes through and is slidably connected to the surface of the mounting plate. A support plate is fixedly connected to the top of the positioning rod. Four sets of protruding strips are fixedly connected to the surface of the support plate, and sponge blocks are inserted between the four sets of protruding strips.

[0008] The bottom end of the positioning rod is fixedly connected to a limit block.

[0009] The support plate and the mounting plate are elastically connected by a return spring.

[0010] The inclined plate has a mounting groove on its surface, and multiple sets of arrayed rollers are rotatably connected inside the mounting groove.

[0011] The mounting plate is fixedly connected to the surface of the top material sliding plate by four sets of telescopic rods.

[0012] Compared with the prior art, the present invention provides a rotary shaft machining ejector device, which has the following beneficial effects:

[0013] 1. This rotary shaft machining ejector device drives a bidirectional threaded rod to rotate via a rotating wheel, causing the slider to move in opposite directions within the groove. This allows for flexible control of the distance between the two sets of inclined plates, greatly improving the device's versatility and applicability. When faced with machining various rotary shafts of different specifications, it eliminates the need for frequent changes to the ejector device, saving time and costs associated with equipment replacement and increasing production efficiency. Simultaneously, the rollers on the inclined plates fit snugly against the outer wall of the rotary shaft, supporting it while facilitating its rotation. This reduces friction during rotation, minimizing damage to the shaft's surface and ensuring its surface quality.

[0014] 2. This rotary shaft machining ejector device uses a return spring to ensure that the sponge block on the support plate is tightly fitted against the outer wall of the rotary shaft. As the shaft rotates, the sponge block promptly removes impurities and debris from its surface. This not only ensures the cleanliness of the machined surface, improving machining accuracy, but also reduces wear on the cutting tools, extending tool life and lowering production costs. Furthermore, the sponge block is secured by protruding strips, facilitating easy replacement of soiled blocks. Operation is simple and convenient, with low maintenance costs.

[0019] like Figures 1-3 As shown, this utility model provides a technical solution: a rotating shaft processing top material device, including a top material slide plate 1, a through hole on the surface of the top material slide plate 1, and a lead screw 2 threadedly connected in the through hole. The top end of the lead screw 2 is rotatably connected to a mounting plate 3, and the bottom end of the lead screw 2 is fixedly connected to a handwheel 4. The mounting plate 3 and the surface of the top material slide plate 1 are fixedly connected by four sets of telescopic rods 5. The lead screw 2 is driven to rotate by rotating a rotating wheel 64. Under the guidance of the four sets of telescopic rods 5, the mounting plate 3 can stably move up and down, thereby approaching the outer wall of the rotating shaft and supporting the rotating shaft.

[0020] An adjustment assembly 6 is provided on the surface of the mounting plate 3. The adjustment assembly 6 includes a groove 61, which is formed on the surface of the mounting plate 3. Two sets of symmetrically arranged sliders 62 are slidably connected inside the groove 61. The two sets of sliders 62 are threaded together by a bidirectional threaded rod 63, which passes through and is rotatably connected to the side wall of the mounting plate 3. A rotating wheel 64 is fixedly connected to the end of the bidirectional threaded rod 63. An inclined plate 65 is fixedly connected to the surface of the sliders 62. The rotating wheel 64 drives the bidirectional threaded rod 63 to rotate, causing the sliders 62 to move towards each other or away from each other, thereby controlling the distance between the two sets of inclined plates 65, so that the top-loading device can be used for rotating shafts of different diameters. An installation groove 66 is formed on the surface of the inclined plate 65. Multiple sets of arrayed rollers 67 are rotatably connected inside the installation groove 66. The installation groove 66 is used to install the rollers 67. When the inclined plate 65 is close to the rotating shaft, the rollers 67 fit against the outer wall of the rotating shaft, thereby facilitating the rotation of the rotating shaft.

[0021] A cleaning component 7 is provided on the surface of the mounting plate 3. The cleaning component 7 includes a positioning rod 71, which passes through and is slidably connected to the surface of the mounting plate 3. A limit block 72 is fixedly connected to the bottom end of the positioning rod 71, and a support plate 73 is fixedly connected to the top end of the positioning rod 71. The support plate 73 and the mounting plate 3 are elastically connected by a return spring 74. The return spring 74 provides elastic support, causing the support plate 73 to move upward and closer to the outer wall of the rotating shaft. The limit block 72 is used to limit the bottom end of the positioning rod 71 to prevent it from falling off. Four sets of protruding strips 75 are fixedly connected to the surface of the support plate 73, and sponge blocks 76 are inserted between the four sets of protruding strips 75. The four sets of protruding strips 75 are used to restrict the sponge blocks 76 and fix them to the surface of the support plate 73. By tightly adhering the sponge blocks 76 to the outer wall of the rotating shaft, the outer wall of the rotating shaft is cleaned during rotation.

[0022] In this invention, during use, the top material slide plate 1 is first installed in a suitable position on the processing equipment to ensure the overall stability of the device. Then, according to the height of the rotating shaft, the handwheel 4 is turned, which drives the lead screw 2 to rotate. Since the lead screw 2 is threadedly connected to the through hole on the surface of the top material slide plate 1, and under the guidance of the four sets of telescopic rods 5, the mounting plate 3 will stably move up and down until it approaches a suitable position near the outer wall of the rotating shaft, providing a preliminary support foundation for the rotating shaft.

[0023] Next, according to the diameter of the rotating shaft, the rotating wheel 64 is rotated, which drives the bidirectional threaded rod 63 to rotate. Because the two sets of sliders 62 are threadedly connected by the bidirectional threaded rod 63, the rotation of the bidirectional threaded rod 63 will cause the sliders 62 to move towards each other or away from each other in the groove 61, thereby controlling the distance between the two sets of inclined plates 65, so that the rollers 67 on the inclined plates 65 fit tightly against the outer wall of the rotating shaft, in order to accommodate rotating shafts of different diameters and facilitate the rotation of the rotating shaft.

[0024] Before the rotating shaft begins machining, the return spring 74 uses its elasticity to support the support plate 73, causing it to move upwards and closer to the outer wall of the rotating shaft. At this time, the sponge block 76 is in close contact with the outer wall of the rotating shaft. During the rotation of the rotating shaft, the sponge block 76 cleans the outer wall of the rotating shaft, removing impurities and debris from the surface to ensure the quality of the machined surface of the rotating shaft.

[0025] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
