Description

Technical Field

[0001] This utility model relates to the field of gear hobbing machine technology, specifically to a gear hobbing machine that is convenient for automatic feeding. Background Technology

[0002] The gear hobbing machine is one of the most widely used gear processing machine tools. It can cut spur gears, helical gears, worm gears, sprockets, etc. It is a gear processing machine tool that uses hobs to process spur gears, helical gears, herringbone gears, and worm gears using the generating method. When using specially made hobs, this machine tool can also process splines, sprockets, and other workpieces with special tooth profiles.

[0003] A vertical gear hobbing machine, disclosed in CN116511613A, includes a support frame; a portal frame is fixedly connected to the support frame; a rotating shaft is rotatably connected to the portal frame; a first mounting plate is fixedly connected to the rotating shaft; a second mounting plate is fixedly connected to the rear end of the first mounting plate; a sliding assembly is connected to the second mounting plate; a slide rod is hinged to the sliding assembly; a drive assembly is connected to the front side of an adjusting plate; a drive shaft is connected to the drive assembly; gears are fixedly connected to the drive shaft; a third mounting plate is fixedly connected to the support frame; a moving part is rotatably connected to the drive shaft; a connecting part is fixedly connected to the moving part; the connecting part is fixedly connected to the adjusting plate; the first and third mounting plates are respectively provided with drive shaft grooves that cooperate with the movement of the drive shaft; by adjusting the positional relationship between the gears and the workpiece, workpieces with different tooth height requirements can be processed without changing gears of different sizes.

[0004] The aforementioned existing technology has some defects in use. When using it, it is not convenient to adjust the tilt of the adjustment plate by driving the slide bar, and it cannot be adjusted infinitely, which can easily lead to reverse movement. At the same time, the top only provides reverse compression force through a simple compression spring. When the spring rebounds, it adjusts non-linearly according to different compression amplitudes. This results in excessive resistance when the tilt angle is large, while when the tilt angle is small, it is easy to fail to push the adjustment plate to rotate in the reverse direction, which affects the rotation and reset of the adjustment plate. Utility Model Content

[0005] The purpose of this invention is to provide a convenient automatic feeding gear hobbing machine, which solves the problems of existing gear hobbing machines that cannot be adjusted linearly, are prone to reverse movement, and are not convenient for reset and rotational movement.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a gear hobbing machine with convenient automatic feeding, comprising a base plate, a support plate slidably connected to the top of the base plate, an inclined plate rotatably connected to the top of the support plate, a top plate provided on the top of the inclined plate, a rotating rod rotatably connected to one side of the inclined plate, and an extrusion plate slidably connected to the side of the inclined plate away from the rotating rod.

[0007] The bottom of the inclined plate is rotatably connected to a drive rod, and a rotating gear is fixedly connected to the outer wall of one end of both the drive rod and the rotating rod. A transmission toothed belt is installed on the outer wall of both rotating gears.

[0008] An adjusting plate is slidably connected to the bottom of the top plate, and a push plate is slidably connected to the bottom of the top plate near the inclined plate. A compression spring is fixedly connected to the end of the push plate near the adjusting plate.

[0009] The outer wall of the rotating rod is provided with multiple fixing grooves, and multiple cutting wheels are sleeved on the outer wall of the rotating rod. The inside of each cutting wheel is threaded with fixing bolts.

[0010] Preferably, a connecting plate is slidably connected to one side of the top of the base plate, the bottom end of one side of the connecting plate is fixedly connected to the support plate, the top end of the connecting plate near the support plate is fixedly connected to the top plate, and one side of the extrusion plate is vertically slidably connected to the side wall of the connecting plate.

[0011] Preferably, the end of the support plate away from the connecting plate is bent towards the bottom and slidably connected to the base plate. A placement frame is fixedly installed on the top of the base plate away from the support plate. A first lead screw is installed on the side of the placement frame close to the support plate. The outer wall of the first lead screw is threadedly connected to the support plate and the connecting plate respectively. A drive motor is installed on the end of the first lead screw away from the placement frame.

[0012] Preferably, a second lead screw is threadedly connected to the center of the end of the extrusion plate away from the inclined plate. A driven gear is fixedly connected to the outer wall of the bottom end of the second lead screw. A driving gear is meshed with one side of the driven gear. A rotating motor is installed at the bottom end of the driving gear, and the power output end of the rotating motor passes through the interior of the support plate and is fixedly connected to the driving gear.

[0013] Preferably, the bottom of the inclined plate is rotatably connected to the outer wall of the drive rod via a rotating shaft, the outer wall of the drive rod is rotatably connected to the top of the support plate via a rotating shaft, a rotary motor is installed at the end of the drive rod away from the rotating gear, both ends of the transmission toothed belt are meshed with the rotating gear, and a slide rod is fixedly connected to the side of the inclined plate near the extrusion plate, and the slide rod is slidably connected to one end of the extrusion plate.

[0014] Preferably, the top of the inclined plate, away from the extrusion plate, is pressed against the side of the push plate; one end of the electric push rod is fixedly connected to the connecting plate; the inner protruding end of the electric push rod is fixedly connected to the adjusting plate; and the end of the compression spring away from the push plate is fixedly connected to the adjusting plate.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. The rotating gear drives the rotating gear at one end of the rotating rod to rotate via the transmission gear belt, causing the rotating rod to rotate. This causes the cutting wheel on the outer wall of the rotating rod to rotate, thereby cutting the workpiece. At the same time, it is easy to rotate the fixing bolt during use, thereby releasing the fixing bolt from the fixing groove and releasing the fixing of the cutting wheel. This allows for easy adjustment of the cutting wheel's position to meet different processing spacing requirements.

[0017] 2. The rotating gear drives the rotating rod to rotate via a transmission belt, causing the rotating rod to rotate. This rotation of the rotating rod causes the cutter wheel on the outer wall of the rotating rod to rotate, thus cutting the material. At the same time, the fixing bolt can be easily rotated during use to release the clamping between the fixing bolt and the fixing groove, thereby releasing the fixing of the cutter wheel. This allows for easy adjustment of the cutter wheel's position to meet different processing spacing requirements.

[0018] 3. Activate the electric push rod, causing it to extend and move the adjusting plate away from the tilting plate. This causes the compression spring to extend, adjusting its rebound force to prevent excessive force. When the tilting plate needs to be reset, the compression plate moves upward, releasing the pressure on the tilting plate. This causes the compression spring to rebound, pushing the tilting plate in the opposite direction via the push plate. When the compression spring force is low, the electric push rod retracts, moving the adjusting plate to one side of the tilting plate. This compresses the compression spring, allowing it to further push the push plate, thus resetting the tilting plate. This effectively prevents the tilting plate from failing to be reset by the compression spring. Attached Figure Description

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figure 1-5 The gear hobbing machine shown includes a base plate 1, a support plate 2 slidably connected to the top of the base plate 1, an inclined plate 3 rotatably connected to the top of the support plate 2, a top plate 4 on the top of the inclined plate 3, a rotating rod 5 rotatably connected to one side of the inclined plate 3, and a pressing plate 6 slidably connected to the side of the inclined plate 3 away from the rotating rod 5; a drive rod 301 rotatably connected to the bottom of the inclined plate 3, and rotating gears 302 fixedly connected to the outer walls of one end of the drive rod 301 and the rotating rod 5, with transmission gear belts 303 installed on the outer walls of both rotating gears 302; an adjusting plate 401 slidably connected to the bottom of the top plate 4, and a push plate 403 slidably connected to the bottom of the top plate 4 near the inclined plate 3, with a pressing spring 404 fixedly connected to the end of the push plate 403 near the adjusting plate 401; multiple fixing grooves 501 are opened on the outer wall of the rotating rod 5, and multiple cutter wheels 502 are sleeved on the outer wall of the rotating rod 5, with fixing bolts 503 threaded inside each cutter wheel 502.

[0029] like Figure 2 , Figure 3As shown, a connecting plate 201 is slidably connected to one side of the top of the base plate 1. The bottom end of one side of the connecting plate 201 is fixedly connected to the support plate 2. The top end of the connecting plate 201 near the support plate 2 is fixedly connected to the top plate 4. One side of the extrusion plate 6 is vertically slidably connected to the side wall of the connecting plate 201. The end of the support plate 2 away from the connecting plate 201 is bent towards the bottom and slidably connected to the base plate 1. A placement rack 102 is fixedly installed on the top side of the base plate 1 away from the support plate 2. A first lead screw is installed on the side of the placement rack 102 near the support plate 2. 101. The outer wall of the first lead screw 101 is threadedly connected to the support plate 2 and the connecting plate 201 respectively. A drive motor is installed at the end of the first lead screw 101 away from the placement frame 102. Since the extrusion plate 6 slides along the connecting plate 201, it can continuously extrude the inclined plate 3, realizing stepless adjustment. Moreover, during use, the first lead screw 101 can be rotated by rotating the motor, so that the support plate 2 and the connecting plate 201 slide along the base plate 1, thereby further adjusting the position of the inclined plate 3 and the workpiece.

[0030] like Figure 2 , Figure 4 As shown, a second lead screw 601 is threadedly connected to the center of the end of the extrusion plate 6 away from the inclined plate 3. A driven gear 602 is fixedly connected to the outer wall of the bottom end of the second lead screw 601. A driving gear 603 is meshed with one side of the driven gear 602. A rotating motor is installed at the bottom end of the driving gear 603, and the power output end of the rotating motor passes through the interior of the support plate 2 and is fixedly connected to the driving gear 603. The bottom of the inclined plate 3 is rotatably connected to the outer wall of the drive rod 301 through a rotating shaft. The outer wall of the drive rod 301 is rotatably connected to the top of the support plate 2 through a rotating shaft. A rotating... Both ends of the motor and the transmission belt 303 are meshed with the rotating gear 302. A slide rod 304 is fixedly connected to the side of the inclined plate 3 near the extrusion plate 6, and the slide rod 304 is slidably connected to one end of the extrusion plate 6. The rotation of the driving gear 603 drives the driven gear 602 to rotate, thereby causing the second lead screw 601 to rotate. Since the second lead screw 601 is threadedly connected to the extrusion plate 6, and the extrusion plate 6 is slidably connected to the inclined plate 3 and the connecting plate 201 respectively, the rotation of the second lead screw 601 can drive the extrusion plate 6 to slide along the connecting plate 201, thereby causing the extrusion plate 6 to extrude the inclined plate 3.

[0031] like Figure 1 , Figure 5As shown, the top of the inclined plate 3, away from the pressing plate 6, is pressed against the side of the push plate 403. One end of the electric push rod 402 is fixedly connected to the connecting plate 201, and the inner protruding end of the electric push rod 402 is fixedly connected to the adjusting plate 401. The end of the compression spring 404 away from the push plate 403 is fixedly connected to the adjusting plate 401. When the electric push rod 402 is activated, it extends, causing the adjusting plate 401 to move away from the inclined plate 3, thereby causing the compression spring 404 to extend. This adjusts the rebound force of the compression spring 404 to avoid excessive elasticity. When the inclined plate 3 needs to be reset, the pressing plate 6 moves to the top, releasing the pressure on the inclined plate 3. This causes the compression spring 404 to rebound, and then the compression spring 404 pushes the inclined plate 3 to rotate and move in the opposite direction through the push plate 403. When the elasticity of the compression spring 404 is small, the electric push rod 402 can contract, causing the adjusting plate 401 to move towards the side of the inclined plate 3, thereby compressing the compression spring 404.

[0032] In use, the workpiece to be processed can be conveniently mounted on the top surface of the placement rack 102, and then the drive rod 301 can be rotated, which in turn causes the rotating gear 302 at one end of the drive rod 301 to rotate. The rotating gear 302 then drives the rotating gear 302 at one end of the rotating rod 5 to rotate through the transmission belt 303, so that the rotating rod 5 rotates accordingly. This causes the cutter wheel 502 on the outer wall of the rotating rod 5 to rotate, thereby cutting the workpiece through the rotation of the cutter wheel 502. At the same time, in use, the fixing bolt 503 can be easily rotated to release the clamping fixation between the fixing bolt 503 and the fixing groove 501, thereby releasing the fixation of the cutter wheel 502. This allows for easy adjustment of the position of the cutter wheel 502 to meet different processing spacing requirements.

[0033] In use, the rotation of the driving gear 603 drives the driven gear 602 to rotate, thereby causing the second lead screw 601 to rotate. Since the second lead screw 601 is threadedly connected to the extrusion plate 6, and the extrusion plate 6 is slidably connected to the inclined plate 3 and the connecting plate 201 respectively, the rotation of the second lead screw 601 can drive the extrusion plate 6 to slide along the connecting plate 201, thereby causing the extrusion plate 6 to extrude on the inclined plate 3. This causes the inclined plate 3 to rotate further around the bottom drive rod 301, which in turn drives the rotating rod 5 to move, thus achieving the adjustment of the cutter wheel 5. The position of 02 is adjusted so that the extrusion plate 6 cannot drive the second lead screw 601 to rotate, thus effectively preventing the extrusion plate 6 from moving in the opposite direction, thereby preventing the tilting plate 3 from rotating in the opposite direction and preventing the cutting wheel 502 from becoming loose during cutting. At the same time, since the extrusion plate 6 slides along the connecting plate 201, it can continuously extrude the tilting plate 3, achieving stepless adjustment. Moreover, during use, the first lead screw 101 can be rotated by rotating the motor, so that the support plate 2 and the connecting plate 201 slide along the base plate 1, thereby further adjusting the position of the tilting plate 3 and the workpiece.

[0034] In use, the tilting plate 3 tilts to press the push plate 403, which in turn presses the compression spring 404, thus compressing the compression spring 404. When the compression spring 404 is highly compressed, the electric push rod 402 is activated, extending to move the adjusting plate 401 away from the tilting plate 3. This causes the compression spring 404 to extend further, adjusting its rebound force and preventing excessive force. When the tilting plate 3 needs to be reset, the compression plate 6 moves upward to release the tilting plate. The compression of plate 3 causes the compression spring 404 to rebound, which in turn pushes the inclined plate 3 to rotate and move in the opposite direction via the push plate 403. When the spring force of the compression spring 404 is small, the electric push rod 402 can retract and drive the adjusting plate 401 to move to one side of the inclined plate 3, thereby compressing the compression spring 404. This allows the compression spring 404 to further push the push plate 403 to move, thereby resetting the inclined plate 3. This effectively avoids the situation where the inclined plate 3 cannot be pushed back to its original position by the compression spring 404.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
