Description

Technical Field

[0001] The utility model relates to the technical field of friction plate processing and production, in particular to a knife shaft component adjustment mechanism and a grooving machine. Background Art

[0002] Friction plates and clutch plates are common mechanical parts. In order to improve the braking effect of the friction plates and the separation or engagement effect of the clutch plates, it is necessary to process oil grooves on the surface of the friction plates or clutch plates. Existing oil groove processing is generally modified from a benchtop drilling machine, a manual mechanical indexing plate, and an electromagnetic chuck. Existing machine tools are composed of five major parts: a bed part, a column part, a workbench part, a tool holder body part, and a differential mechanism. Traditional grooving equipment adjusts the position of the workpiece groove by adjusting the workpiece; or calculates the position of the workpiece groove by calculating the thickness of the spacer ring; both methods are too cumbersome and have a number of adjustment levels, that is, the thickness of the spacer ring is the minimum adjustment unit, resulting in large errors and inaccurate slotting positions. Utility Model Content

[0003] Technical problems to be solved by utility models

[0005] Technical Solution

[0006] In order to solve the above problems, the technical solution provided by the present invention is as follows:

[0007] A knife shaft component adjustment mechanism includes a knife shaft; a fixed seat, which is provided with a pair and symmetrically distributed about the knife shaft; a fixed sleeve, which is axially slidably connected in the fixed seat, which is a split structure and has a sleeve clamping block on it, one side of one of the fixed sleeves is provided with teeth, and the teeth are matched with an adjustment gear; a rotating sleeve, which is rotatably connected in the fixed sleeve, and a limit screw threadedly connected to the knife shaft is provided inside the fixed sleeve, the axial threaded connection length of the limit screw and the knife shaft is adjustable, and the limit screw is limit-engaged in the rotating sleeve.

[0008] Knife shaft: This is the core component of the entire adjustment mechanism and is responsible for the actual cutting or marking work.

[0009] Fixed seat: The design of the fixed seat enables the cutter shaft to be stably mounted on the machine, and through a pair of fixed seats symmetrically distributed about the cutter shaft, the balance and stability of the cutter shaft during operation are ensured.

[0010] Fixed Sleeve: The fixed sleeve adopts a split structure design and is equipped with a sleeve clamping block. This allows the fixed sleeve to be firmly fixed in the fixed seat and also allows for easy disassembly and adjustment. The fixed sleeve is equipped with teeth on one side, which cooperate with the adjustment gear to achieve precise adjustment of the axial position of the cutter shaft.

[0011] Rotating sleeve: The rotating sleeve has a threaded interior that forms a threaded connection with the limit screw on the cutter shaft. By rotating the rotating sleeve, the length of the threaded connection between the limit screw and the cutter shaft can be changed, thereby adjusting the position of the cutter shaft along the axial direction.

[0012] Adjusting gear: meshes with the teeth on the fixed sleeve, and is driven to rotate manually or electrically, thereby driving the fixed sleeve to move and achieve fine-tuning of the knife shaft position.

[0013] Limit screw: The limit screw not only plays a connecting role, but also can move inside the rotating sleeve to limit or adjust the axial position of the tool shaft to ensure the accurate position of the tool during processing.

[0014] Optionally, one of the rotating sleeves is connected to a driving device.

[0015] The rotation of the rotating sleeve can be automated by connecting a drive device, which provides the power for the knife shaft to rotate.

[0019] The outer wall of the rotating sleeve is connected to the inner wall of the stationary sleeve via multiple bearings. These bearings allow the rotating sleeve to rotate freely within the stationary sleeve while maintaining high precision and low friction. The multiple bearings disperse the radial and axial forces generated by the rotating sleeve, reducing the load on individual bearings and improving the overall stability and lifespan of the system.

[0022] Optionally, the adjusting gear is connected to an adjusting rod, and the adjusting rod is rotatably connected to the outside of a fixing seat having the adjusting gear.

[0023] The adjusting gear meshes with the teeth on the fixed sleeve, and rotating the adjusting gear drives the fixed sleeve axially. The adjusting rod is connected to the adjusting gear, and rotating the adjusting rod indirectly drives the adjusting gear to rotate. The adjusting rod is rotatably connected to the fixed base with the adjusting gear, ensuring that the rotational motion of the adjusting rod is smoothly transmitted to the adjusting gear.

[0024] Optionally, the sleeve clamping block is a bolt, and the two split structural parts of the fixed sleeve are provided with corresponding threaded holes, and the bolt is fastened in cooperation with the threaded holes.

[0035] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments.

[0036] Example 1

[0037] Combined with attachment Figure 1-3 A tool shaft adjustment mechanism includes a fixing seat 1, a fixing seat 2, a fixing sleeve 3, a fixing sleeve 4, a sleeve clamping block 5, a sleeve clamping block 6, an adjusting gear 7, a pulley 8, a locking nut 9, a locking nut 10, a shaft spacer 11, a processing blade 12, a blade spacer sleeve 13, a rotating sleeve 14, a rotating sleeve 15, a limit screw 16, a limit screw 17, a tool shaft 18 and a tapered surface 19.

[0038] The cutter shaft 18 is equipped with multiple layers of parallel, annular working blades 12 that can be rotated to create grooves. The shaft 18 is also equipped with an on-axis spacer 11, which controls the initial position of the working blades 12 when loading them. Adjustment mechanisms are used after loading. Blade spacers 13 are positioned between the working blades 12 to set the distance between them. Locking nuts 1 (9) and 2 (10) are located at each end of each on-axis spacer 11 to secure the spacers 11.

[0039] The fixed seat is provided in a pair and is symmetrically distributed about the knife axis 18, including a fixed seat 1 located above and a fixed seat 2 located below. The fixed sleeve and rotating sleeve introduced later are also divided into fixed sleeve 1 3 and fixed sleeve 2 4, as well as rotating sleeve 1 14 and rotating sleeve 2 15 according to their positions.

[0040] The fixed sleeve is axially slidably connected to the fixed seat. It is a split structure and is provided with a sleeve clamping block. One side of the fixed sleeve is provided with teeth, and the teeth are matched with an adjustment gear 7. The sleeve clamping block is divided into sleeve clamping block 1 5 and sleeve clamping block 2 6.

[0041] The rotating sleeve is rotatably connected to the fixed sleeve and internally includes a stop screw threadedly connected to the blade shaft 18. The axial threaded connection length between the stop screw and the blade shaft 18 is adjustable, and the stop screw is fixedly engaged with the rotating sleeve. The stop screws include stop screw 16 and stop screw 2 17, which correspond to rotating sleeve 14 and rotating sleeve 2 15, respectively.

[0042] One of the rotating sleeves is connected to a drive device. The rotating sleeve connected to the drive device has an axial extension. A pulley 8 is fixedly mounted on the extension. This pulley 8 is connected to the drive device via a belt. When the drive device (motor) is started, the motor's output shaft rotates, transmitting the rotational motion to pulley 8 via the belt. Pulley 8 rotates accordingly, driving the rotating sleeve to which it is attached.

[0043] The rotating sleeve is rotatably connected to the inner wall of the fixed sleeve via multiple bearings. When a driving device (such as a motor) drives pulley 8 via a belt, pulley 8 drives the rotating sleeve. Because the rotating sleeve and the fixed sleeve are connected by multiple bearings, the rotating sleeve rotates smoothly within the fixed sleeve, ensuring precise axial movement of the limit screw.

[0044] The connection between the rotating sleeve and the cutter shaft 18 is abutted by a tapered surface 19. The end of the rotating sleeve is provided with a tapered groove. The end of the cutter shaft 18 is tapered and the two are adapted to each other. Connection and positioning: When the cutter shaft 18 is inserted into the tapered groove of the rotating sleeve, the abutment of the tapered surface 19 ensures the precise alignment and tight connection between the cutter shaft 18 and the rotating sleeve. The tapered surface 19 has a large contact area, which can effectively disperse the contact pressure, reduce local stress concentration, and improve the reliability and stability of the connection. Axial adjustment: Through the rotation of the rotating sleeve, the limit screw moves axially under the action of the thread, thereby realizing the adjustment of the position of the cutter shaft 18. The abutment of the tapered surface 19 ensures that the axial position of the cutter shaft 18 always remains precise during the adjustment process and will not be offset due to rotation.

[0045] The adjusting gear 7 is connected to the adjusting rod, and the adjusting rod is rotatably connected to the outside of the fixed seat with the adjusting gear 7. Power transmission: When the operator rotates the adjusting rod, the rotational motion of the adjusting rod is transmitted to the adjusting gear 7. The adjusting gear 7 is engaged with the teeth on the fixed sleeve, and the rotation of the gear drives the fixed sleeve to move axially. The movement of the fixed sleeve causes the rotating sleeve inside the fixed sleeve to move accordingly, thereby driving the limit screw on the knife shaft 18 to move axially, thereby adjusting the position of the knife shaft 18. Adjustment accuracy: Through the combination of the adjusting rod and the adjusting gear 7, fine adjustment of the position of the knife shaft 18 can be achieved. Every degree of rotation of the adjusting rod will be accurately converted into the axial movement of the fixed sleeve, thereby ensuring the accuracy of the adjustment.

[0046] The sleeve clamping block is a bolt, and the two split structural parts of the fixed sleeve are provided with corresponding threaded holes, and the bolt is fastened in cooperation with the threaded holes. Installation of the fixed sleeve: During the installation process, first install the two split structural parts of the fixed sleeve into the fixed seat respectively. Insert the knife shaft 18 into the fixed sleeve, and ensure that the tapered end of the knife shaft 18 is aligned with the tapered groove of the fixed sleeve. Tightening process: Pass the bolt through the corresponding threaded holes on the two split structural parts of the fixed sleeve. Tighten the bolt so that the two split structural parts of the fixed sleeve fit tightly, ensure that the fixed sleeve is firmly fixed in the fixed seat, and clamp the knife shaft 18 at the same time.

[0047] Working principle:

[0048] Initial Installation: Install the two halves of the fixed sleeve into their respective mountings and secure them with bolts. The fixed sleeve contains the rotating sleeve. The fixed and rotating sleeves are secured with axial retaining structures, such as an annular protrusion.

[0049] Insert the cutter shaft 18 into the rotating sleeve, ensuring that the tapered end of the cutter shaft 18 is aligned with and in close contact with the tapered groove of the rotating sleeve. A limit screw is connected to the threaded hole at the end of the cutter shaft 18, and the axial movement and position of the cutter shaft 18 can be controlled by turning the limit screw.

[0050] Position adjustment: When the position of the blade shaft 18 needs to be adjusted, loosen the sleeve clamping block on the fixed sleeve to slightly loosen the two split parts of the fixed sleeve. Rotate the adjustment rod to drive the fixed sleeve 2 4 to move axially through the adjustment gear 7, thereby adjusting the position of the blade shaft 18.

[0051] After the adjustment is completed, tighten the sleeve clamping block again to ensure that the positions of the fixed sleeve and the knife shaft 18 remain unchanged.

[0052] Power Transmission:

[0053] The driving device drives the rotating sleeve and the knife shaft 18 to rotate through the belt and the pulley 8.

[0054] A grooving machine includes the aforementioned tool shaft 18 component adjustment mechanism. A grooving machine is a mechanical device used to draw predetermined groove lines on the surface of a workpiece, and is widely used in wood processing, metal processing, stone processing and other fields. Its main components include: a frame: providing support and fixation for the entire device. A workbench: used to place and fix the workpiece to be processed. A tool shaft 18 component adjustment mechanism: used to precisely adjust the position of the tool shaft 18 to ensure processing accuracy. A drive system: provides power to drive the tool shaft 18 to rotate and the workpiece to move. A control system: used to control and monitor the operating status of the equipment to achieve automated operation.

[0055] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the inventive purpose of the present invention, designs a structure and embodiment similar to the technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
