Description

Technical Field

[0001] This utility model relates to the field of knurling machine technology, specifically a horizontal knurling machine with adjustable knurling wheels. Background Technology

[0002] In the machining process of mechanical workpieces, knurling machines form regular patterns on the surface of workpieces through the extrusion and friction between knurling wheels and the workpieces, thereby improving the anti-slip performance or aesthetics of the workpieces. However, traditional horizontal knurling machines have the following problems. First, the knurling wheels are generally directly connected to the frame and rotated by a motor to achieve the knurling treatment on the workpiece surface. However, this method is not convenient for adjusting the distance between the knurling wheels, and therefore cannot meet the processing requirements of workpieces of different thicknesses and specifications. It has low versatility and cannot be adjusted according to actual needs, resulting in poor flexibility. Therefore, this utility model proposes a horizontal knurling machine with adjustable knurling wheels to specifically solve this problem. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a horizontal knurling machine with adjustable knurling wheels. By setting up a knurling wheel assembly, which includes a shaft, driven gear, round rod, sliding block, connecting rod, and knurling wheel body, the sliding block is slidably connected to a corresponding track plate. A hydraulic cylinder can drive the track plate to rise and fall. During the rising and falling of the track plate, the sliding block can extend and retract, simultaneously controlling the shaft to rotate. This causes the driven gear to rotate around the driving gear under the action of the connecting rod, adjusting the distance between the two knurling wheel bodies. Furthermore, after the distance is adjusted, the meshing relationship between the driving and driven gears is maintained, without affecting the rotational drive of the knurling wheel body. This solves the problem of the current devices having non-adjustable knurling wheels, resulting in low device versatility.

[0005] (II) Technical Solution

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

[0007] A horizontal knurling machine with adjustable knurling wheels includes an outer frame. Two symmetrically distributed inner frames are fixedly connected to the inner side of the outer frame. Each inner frame is equipped with a rotating component. The rotating component includes a rotating rod, support rods fixedly connected to both ends of the rotating rod, and a drive gear coaxially fixed to the support rod. The support rod is rotatably connected to the corresponding inner frame. The machine also includes a knurling wheel assembly. The knurling wheel assembly includes a knurling wheel body, shafts coaxially fixed to both ends of the knurling wheel body, and a driven gear fixedly connected to the shaft. The driven gear meshes with the corresponding drive gear. A connecting rod rotatably connects the support rod and the corresponding shaft. The shaft and the driven gear rotate planetarily around the drive gear through the connecting rod, thereby adjusting the distance between the two knurling wheel bodies.

[0008] Furthermore, an array of printed protrusions are fixedly connected to the outer wall of the knurling wheel body.

[0009] Furthermore, an adjustment assembly is fixedly connected to the outer wall of the outer frame, and the adjustment assembly is associated with the knurling wheel assembly. The adjustment assembly includes a hydraulic cylinder, a horizontal plate, and a track plate. One side of the horizontal plate is integrally formed with an ear plate, which is fixedly connected to the outer wall of the outer frame by bolts. The hydraulic cylinder is installed on the horizontal plate, and a hydraulic telescopic rod is provided on one side of the hydraulic cylinder. The end of the hydraulic telescopic rod is connected and fixed to the track plate through a fixing seat.

[0010] Furthermore, a round rod is coaxially rotatably connected to the end of the shaft, and a sliding block is fixedly connected to the end of the round rod away from the shaft, and the sliding block is slidably connected to the corresponding track plate.

[0011] Furthermore, a motor is installed on one side of the outer frame, and the output shaft of the motor is coaxially connected and fixed with the corresponding support rod.

[0012] Furthermore, the connecting rod is equipped with a clearance-fit bearing between itself and the corresponding shaft and support rod.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a horizontal knurling machine with an adjustable knurling wheel, which has the following advantages:

[0015] 1. This utility model achieves precise adjustment of the knurling wheel body spacing through the linkage structure of the knurling wheel assembly and the adjustment assembly: when the hydraulic cylinder of the adjustment assembly drives the hydraulic telescopic rod to extend or retract, the track plate drives the sliding block to move (the sliding block slides on the track plate), and the sliding block pulls the shaft through the round rod, so that the shaft and the driven gear perform planetary motion around the driving gear under the constraint of the connecting rod: during this process, the spacing between the two knurling wheel bodies can be freely adjusted according to the workpiece specifications, and after adjustment, the driven gear and the driving gear still maintain a meshing state, which does not affect the rotation drive of the knurling wheel, thus solving the problem of "fixed knurling wheel position and inability to adapt to workpieces of different thicknesses / diameters" in traditional knurling machines, and is suitable for knurling processing of workpieces of various specifications, significantly improving its versatility.

[0016] 2. In this utility model, the connecting rod, shaft, and support rod are connected by bearings with clearance fit, which reduces rotational friction and avoids loosening or jamming during the adjustment process; the horizontal plate of the adjustment component is fixed to the outer frame by ear plates and bolts, and the sliding fit between the track plate and the sliding block provides guidance for the adjustment, ensuring that the knurled wheel adjustment process is smooth and without shaking.

[0022] 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.

[0023] Example

[0024] like Figure 1 , Figure 2 and Figure 3 As shown in the figure, an embodiment of the present invention discloses a horizontal knurling machine with an adjustable knurling wheel, comprising an outer frame 1, with two symmetrically distributed inner frames 2 fixedly connected to the inner side of the outer frame 1. The outer frame 1 is the main body of the device and can be fixed to a machine frame or other object for installation and fixation during use. Rotating components 3 are provided on both inner frames 2. The inner frames 2 are used for mounting the rotating components 3. When the rotating components 3 are in operation, they can perform knurling treatment on the workpiece. The rotating components 3 include a rotating rod 301 and support rods 30 fixedly connected to both ends of the rotating rod 301. 2. A drive gear 303 is coaxially fixed on the support rod 302. When one drive gear 303 rotates, the two drive gears 303 can rotate synchronously through the relationship between the rotating rod 301 and the support rod 302. The support rod 302 is rotatably connected to the corresponding inner frame 2, thereby achieving stable rotation of the rotating rod 301, the support rod 302, and the drive gear 303. The horizontal knurling machine also includes a knurling wheel assembly 4. The knurling wheel assembly 4 cooperates with the rotating component 3 to realize the operation of the knurling wheel assembly 4. The knurling wheel assembly 4 includes a knurling wheel body 406 and a drive gear 303 coaxially fixed on the support rod 302. The wheel body 406 has shafts 401 at both ends and driven gears 402 fixedly connected to the shafts 401. The driven gears 402 mesh with the corresponding driving gears 303, thereby driving the rotation of the shafts 401 and the knurling wheel body 406. The knurling wheel body 406 is used for printing on the surface of the workpiece. A connecting rod 405 is rotatably connected between the support rod 302 and the corresponding shaft 401. The shafts 401 and driven gears 402 rotate planetarily around the driving gears 303 via the connecting rod 405, thereby adjusting the distance between the two knurling wheel bodies 406. The lever 405 enables the driven gear 402 to perform planetary rotation around the driving gear 303. During rotation, the distance between the two knurling wheel bodies 406 can be adjusted, thereby meeting the processing requirements of workpieces with different thicknesses. It has strong versatility. Furthermore, since the driven gear 402 and the knurling wheel body 406 rotate planetarily, the meshing relationship between the driven gear 402 and the driving gear 303 can be maintained in real time. That is, the rotation operation of the knurling wheel body 406 can be realized at any angle and time. The adjustment of the knurling wheel body 406 can be achieved without stopping the machine. It has strong functionality and good practical effect.

[0025] like Figure 3 As shown, in some embodiments, an array of printed protrusions 407 are fixedly connected to the outer wall of the knurling wheel body 406.

[0026] It should be noted that when the knurling wheel body 406 rotates, the printing protrusions 407 come into contact with the surface of the workpiece, thereby achieving the knurling treatment on the surface of the workpiece.

[0027] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, an adjustment assembly 5 is fixedly connected to the outer wall of the outer frame 1, and the adjustment assembly 5 is associated with the knurling wheel assembly 4. The adjustment assembly 5 includes a hydraulic cylinder 501, a horizontal plate 502 and a track plate 504. An ear plate 506 is integrally formed on one side of the horizontal plate 502. The ear plate 506 is fixedly connected to the outer wall of the outer frame 1 by bolts. The hydraulic cylinder 501 is installed on the horizontal plate 502, and a hydraulic telescopic rod 503 is provided on one side of the hydraulic cylinder 501. The end of the hydraulic telescopic rod 503 is connected and fixed to the track plate 504 through a fixing seat 505.

[0028] It should be noted that the ear plate 506 is fixedly connected to the outer wall of the outer frame 1 by bolts, which has good stability and realizes the installation and fixation of the adjustment component 5 on the outer frame 1. The hydraulic cylinder 501 can control the extension and retraction of the hydraulic telescopic rod 503 to adjust the height of the track plate 504. This method can adjust the height of the round rod 403, the shaft rod 401 and the knurling wheel body 406, and realize the adjustment of the distance between the two knurling wheel bodies 406.

[0029] like Figure 3 and Figure 4 As shown, in some embodiments, a round rod 403 is coaxially rotatably connected to the end of the shaft 401, and a sliding block 404 is fixedly connected to the end of the round rod 403 away from the shaft 401. The sliding block 404 is slidably connected to the corresponding track plate 504.

[0030] It should be noted that the sliding block 404 is slidably connected to the corresponding track plate 504. When the hydraulic telescopic rod 503 drives the track plate 504 to rise and fall, the sliding block 404 can slide inside the track plate 504. During the rising and falling process, it can move laterally along the track plate 504, controlling the shaft 401 and the knurled wheel body 406 to swing. Under the constraint of the connecting rod 405, the shaft 401 and the knurled wheel body 406 rotate around the driving gear 303 in a planetary motion, maintaining the meshing relationship between the driven gear 402 and the driving gear 303 in real time.

[0031] like Figure 1 and Figure 2 As shown, in some embodiments, a motor 6 is installed on one side of the outer frame 1, and the output shaft of the motor 6 is coaxially connected and fixed with the corresponding support rod 302.

[0032] It should be noted that the motor 6 can drive the rotating rod 301, the support rod 302 and the driving gear 303 to rotate. The driving gear 303 meshes with the driven gear 402 to realize the rotation drive of the knurling wheel body 406, thereby realizing the knurling treatment on the surface of the workpiece.

[0033] like Figure 2 and Figure 3 As shown, in some embodiments, the connecting rod 405 is provided with a clearance fit bearing between it and the corresponding shaft 401 and support rod 302.

[0034] It should be noted that the bearing configuration enables the smooth rotation of connecting rod 405.

[0035] The working principle and usage steps of this utility model are as follows: First, the motor 6 is controlled to work, driving the rotating rod 301, support rod 302, and driving gear 303 to rotate. The driving gear 303 meshes with the driven gear 402. Then, the shaft 401 and the knurling wheel body 406 are controlled to rotate. The workpiece passes horizontally between the two knurling wheel bodies 406, and the knurling treatment of the workpiece is achieved through the printed protrusions 407 on the surface of the knurling wheel body 406. It is necessary to adjust the gap between the two knurling wheel bodies 406. Then, to meet the knurling treatment of workpieces of different thicknesses, the hydraulic cylinder 501 is driven to work, controlling the extension and retraction of the hydraulic telescopic rod 503. The hydraulic telescopic rod 503 controls the raising and lowering of the track plate 504. The sliding block 404 is slidably connected inside the track plate 504. When the track plate 504 is raised or lowered, it can drive the sliding block 404 to rise or fall, and can move laterally along the length of the track plate 504. This process allows the shaft 401 and the knurled wheel body 406 to rotate under the constraint of the connecting rod 405, and to rotate planetarily around the drive gear 303. During the rotation, the distance between the two knurled wheel bodies 406 can be adjusted, while maintaining the meshing relationship between the drive gear 303 and the driven gear 402. This facilitates the rotation drive of the shaft 401 and the knurled wheel body 406. When it is necessary to control the movement of the knurled wheel body 406 in the opposite direction, the hydraulic cylinder 501 can be extended or retracted in the opposite direction.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
