Description

Technical Field

[0001] This utility model relates to the field of gear processing technology, and in particular to a CNC helical gear shaving machine. Background Technology

[0002] A CNC helical gear shaving machine is a type of CNC gear shaving machine. It is mainly used for machining external meshing spur gears, helical gears, drum-shaped gears, small bevel gears, and stepped multi-gears. During operation, the workpiece is clamped on the machining table, and its rotation is controlled. Then, the machining head is moved closer to the workpiece to perform the shaving process.

[0003] However, in the use of existing CNC slant gear shaving machines, the clamping operation of the workpiece to be processed is mainly completed manually. The operator removes the gears that have been processed on the processing table and places the disc to be processed on it. It is difficult to achieve automatic loading and unloading, which not only has high labor costs, but also has the problem of low efficiency.

[0004] Therefore, we propose a CNC slant gear shaving machine to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a CNC inclined gear shaving machine to solve the problems mentioned in the background art.

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

[0007] A CNC inclined gear shaving machine includes a gear shaving machine body and a processing head and a processing table installed inside the gear shaving machine body. A fixed table is fixedly installed on one side of the processing table, and a movable table is installed on the other side of the processing table through a lead screw translation mechanism. The opposite surfaces of the movable table and the fixed table are rotatably connected to a clamping shaft. A drive motor for driving the clamping shaft to rotate is also installed on the other side of the fixed table. A lead screw translation mechanism is also installed between the processing table and the gear shaving machine body to control the forward and backward movement of the processing table relative to the gear shaving machine body.

[0008] An extension platform is installed on the front side of the shaving machine body. A conveyor belt and a material box are installed on the extension platform, and the material box is mounted on the conveyor belt. A material rack is provided at the outlet of the material box. The material rack is used to receive the workpiece to be processed that falls from the material box, and the material rack moves under the control of a telescopic component to send the workpiece to be processed between a pair of clamping shafts.

[0009] In a further embodiment, a plurality of rollers I are rotatably embedded on one pair of opposite sidewalls inside the material box, and a plurality of rollers II are rotatably embedded on the other pair of opposite sidewalls inside the material box.

[0010] In a further embodiment, the second roller and the first roller are evenly distributed along the length of the material box, and the second roller and the first roller are arranged alternately.

[0011] In a further embodiment, the material rack is composed of a support bar, a flat bar, and a vertical bar, and the vertical bar is vertically slidably connected to the support bar. A telescopic component two is installed at the bottom of the support bar, and the output end of the telescopic component two is connected to the bottom end of the vertical bar through a connecting frame.

[0012] In a further embodiment, the two sides of the support strip are provided with a plurality of elastic protrusions evenly distributed.

[0013] In a further embodiment, a slider is provided at one end of the support bar near the vertical bar, and a groove is provided on the surface of the vertical bar for the slider to slide.

[0014] In a further embodiment, a plurality of rollers are uniformly provided on the upper surface of the flat strip, and the rollers are arranged in rows along the length direction of the flat strip.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention features a material rack that catches the workpiece falling from the material box. A telescopic component controls the movement of the workpiece to be fed between a pair of clamping shafts, facilitating clamping and fixing between the shafts, thus achieving automatic feeding.

Detailed Implementation

[0022] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-3A CNC inclined gear shaving machine includes a gear shaving machine body 1, a processing head 2, and a processing table 3. The processing head 2 is installed at the top inside the gear shaving machine body 1, and the processing table 3 is installed at the bottom inside the gear shaving machine body 1 via a pair of lead screw translation mechanisms 2 9 to control the forward and backward translation of the processing table 3. A fixed table 6 is fixedly installed on one side of the processing table 3, and a movable table 5 is installed on the other side of the processing table 3 via a lead screw translation mechanism 1 4. The lead screw translation mechanism 1 4 controls the movable table 5 to move closer to or away from the fixed table 6. The opposing surfaces of the movable table 5 and the fixed table 6 are rotatably connected to a clamping shaft 7. Specifically, the clamping shaft 7 adopts a conical structure to facilitate insertion into the inner hole of a disc and clamping the disc. A drive motor 8 is installed on the side of the fixed table 6 away from the clamping shaft 7. The output shaft of the drive motor 8 is connected to the clamping shaft 7, thereby driving the clamping shaft 7 to rotate.

[0026] Specifically, the lead screw translation mechanism 1 4 and the lead screw translation mechanism 2 9 can adopt the same structure, mainly including a frame, lead screw, slide, rotary motor, etc. When the rotary motor drives the lead screw to rotate, the slide sleeved outside the lead screw moves along the lead screw and is limited by the frame to prevent deflection. The slide in the lead screw translation mechanism 1 4 is fixedly connected to the movable table 5, thereby driving the movable table 5 to move. The slide in the lead screw translation mechanism 2 9 is fixedly connected to the processing table 3, thereby driving the processing table 3 to move.

[0027] Please see Figure 1-3 An extension platform 10 is installed on the front side of the gear shaving machine body 1. A conveyor belt 11 and a material box 12 are mounted on the extension platform 10, with the material box 12 positioned above the conveyor belt 11. A slot larger than the width of the conveyor belt 11 is opened on the front side of the processing table 3, allowing the conveyor belt 11 to insert into the slot when the processing table 3 moves forward. This allows the conveyor belt 11 to extend below the clamping shaft 7. When the clamping shaft 7 is released, the fallen gears can fall onto the conveyor belt 11 and be carried away, achieving automatic material unloading. At that time, the material rack 13 is still a distance away from the clamping shaft 7. The material rack 13 is provided at the discharge port of the material box 12. The material rack 13 is used to receive the workpiece to be processed that falls from the material box 12. The material rack 13 is controlled to move by the telescopic component 14 so as to get closer to the clamping shaft 7. After the gear of the clamping shaft 7 falls off, the workpiece to be processed is sent between a pair of clamping shafts 7. At this time, the clamping shaft 7 clamps the workpiece to be processed, realizing automatic feeding. The telescopic component 14 can be, but is not limited to, a cylinder, a hydraulic cylinder or an electric push rod.

[0028] Please see Figure 3Multiple parts to be processed are stacked vertically inside the material box 12. The parts to be processed fall automatically under the action of gravity. Several rollers 121 are rotatably embedded on one pair of opposite side walls inside the material box 12, and several rollers 122 are rotatably embedded on the other pair of opposite side walls inside the material box 12. The rollers 122 and rollers 121 are evenly distributed along the length of the material box 12, and the rollers 122 and rollers 121 are staggered, which makes the parts to be processed fall more smoothly and reduces sliding friction resistance.

[0029] Please see Figure 4 The material rack 13 consists of a support bar 131, a flat bar 132, and a vertical bar 133. The vertical bar 133 is vertically slidably connected to the support bar 131. The connection between the support bar 131 and the flat bar 132 is rounded. The upper end of the vertical bar 133 is bent away from the flat bar 132, thereby widening the upper opening of the support bar 131 to facilitate the workpiece falling into the support bar 131. When the support bar 131 catches the workpiece and delivers it between a pair of clamping shafts 7, the flat bar 132 is positioned at the discharge port of the material box 12, thus preventing the workpiece from falling further. The vertical bar 133 prevents the workpiece from falling further. When the workpiece falls, it rushes out from under the support bar 131. Considering that after a pair of clamping shafts 7 clamp the workpiece, when the material rack 13 resets and retracts, the vertical bar 133 will be blocked by the workpiece. Therefore, a telescopic member 134 is installed at the bottom of the support bar 131. The output end of the telescopic member 134 is connected to the bottom end of the vertical bar 133 through the connecting frame 135. The extension of the telescopic member 134 causes the vertical bar 133 to move down, so that its upper end face is lower than the lower edge of the clamped workpiece, and the material rack 13 can retract. The telescopic member 134 can be, but is not limited to, a cylinder, a hydraulic cylinder or an electric push rod.

[0030] Furthermore, the support bar portion 131 is provided with a plurality of elastic protrusions 1311 evenly on both sides. The elastic protrusions 1311 are made of elastic rubber and can limit the workpiece to be processed in the support bar portion 131 on both sides to prevent it from tipping over.

[0031] The support bar 131 has a slider 1312 at one end near the vertical bar 133, and the surface of the vertical bar 133 has a groove 1331 for the slider 1312 to slide. The sliding limit effect of the groove 1331 and the slider 1312 improves the stability of the vertical bar 133's lifting and lowering movement.

[0032] The upper surface of the flat bar 132 is uniformly provided with a plurality of rollers 1321, and the rollers 1321 are arranged in rows along the length of the flat bar 132, so that when the material rack 13 moves, the rotation of the rollers 1321 can reduce the direct friction between the flat bar 132 and the workpiece to be processed in the material box 12.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
