Description

Technical Field

[0001] This application relates to the field of clutch technology, and in particular to a transmission clutch device and a blank trimming machine. Background Technology

[0002] As a core piece of equipment in the blank processing field, the blank trimming machine is widely used in industries such as ceramics and building materials. Its core function is to achieve efficient blank processing through multi-station collaborative operation. In multi-station processing scenarios of blank trimming machines, in order to simplify the equipment structure and reduce energy consumption, a "single power source + clutch" power transmission mode is usually adopted. That is, multiple processing stations share the same power source, and the power transmission and disconnection between different stations is controlled by the clutch's engagement and disengagement action. Therefore, the performance of the clutch directly determines the operational stability and processing efficiency of the blank trimming machine. Currently, the clutches used in blank trimming machines in the industry employ two main types: one uses a pure gear transmission structure, which transmits power through gear meshing. While this can meet basic power switching requirements, the gear meshing process is prone to mechanical impact and vibration, resulting in significantly higher noise levels during equipment operation. Furthermore, high-frequency noise and vibration accelerate gear tooth wear, shorten clutch lifespan, and increase equipment maintenance costs. The other type of clutch uses a triangular plate lifting structure, where a clutch lifting cylinder drives the triangular plate to lift and lower, achieving clutch engagement and disengagement. However, this structure is prone to wear and deformation during long-term lifting movements, and deviations in lifting positioning accuracy can lead to inaccurate engagement between the triangular plate and transmission components, resulting in clutch failure and power transmission interruption. Utility Model Content

[0003] This application aims to provide a transmission clutch device and a blank trimming machine to solve the technical problems of high clutch noise and clutch failure during engagement in related technologies.

[0004] To achieve the above objectives, in a first aspect, this application provides a transmission clutch device, comprising: The first half clutch has a first connecting hole through it along the central axis, and a first meshing part is provided around the first connecting hole on one side end face of the first half clutch. The first meshing part is annular and has a plurality of first teeth arranged at intervals along the annular shape. A first tooth groove is formed between adjacent first teeth, and the first tooth groove has a meshing surface arranged opposite to each other. The second half clutch has a second connecting hole through it along the central axis, and a second engagement part is provided around the second connecting hole on one side end face of the second half clutch. The second engagement part is configured to be selectively disengaged from or engaged with the first engagement part. The second engagement part is annular and has a plurality of second teeth arranged at annular intervals. A second tooth groove is formed between adjacent second teeth, and the second tooth groove has a meshing surface arranged opposite to each other.

[0005] In some embodiments, the diameter of the projected annular profile of the first engagement portion along the axis of the first half-clutch is equal to the diameter of the projected annular profile of the second engagement portion along the axis of the second half-clutch.

[0006] In some embodiments, the distance between the opposite end faces of the first tooth groove is equal to the distance between the opposite end faces of the second tooth claw, and the distance between the opposite end faces of the second tooth groove is equal to the distance between the opposite end faces of the first tooth claw.

[0007] In some embodiments, a boss is provided on the end face of the first half clutch away from the first engagement portion, and the first connecting hole extends through to the end face of the boss to the end face of the first half clutch near the first engagement portion.

[0008] In some embodiments, the sidewall of the boss is provided with at least one pin hole that communicates with the first connecting hole, and the pin hole is used for positioning and fixing the first half clutch during installation.

[0009] In some embodiments, the inner sidewall of the first connecting hole is provided with a first keyway along its axial direction, and at least one of the pin holes communicates with the first keyway.

[0010] In some embodiments, the second half-clutch is provided with a connecting hole between the second engagement portion and the second connecting hole, and a plurality of the connecting holes are arranged at intervals around the second connecting hole.

[0011] In some embodiments, the second half-clutch is provided with at least two positioning holes spaced apart between the second engagement portion and the second connecting hole, the positioning holes being offset from the connecting hole.

[0012] In some embodiments, the inner sidewall of the second connecting hole is provided with a second keyway along its axial direction.

[0013] Secondly, this application also provides a trimming machine, which includes a transmission clutch device as described in any of the first aspects above.

[0014] Compared with the prior art, the technical solution provided in this application has at least the following beneficial effects: In the transmission clutch device provided in this application, the first half clutch and the second half clutch are respectively provided with annular first meshing parts and second meshing parts on their corresponding end faces. The first meshing parts and the second meshing parts are respectively provided with multiple first teeth and second teeth at an annular interval. A first tooth groove and a second tooth groove are formed between adjacent first teeth and adjacent second teeth, respectively. The first tooth groove and the second tooth groove have meshing surfaces that are arranged opposite to each other. During the meshing process of the first half clutch and the second half clutch, the contact area between the teeth and the tooth groove is larger and the meshing process is smoother. This can reduce the mechanical impact and high-frequency vibration during gear meshing, thereby reducing noise at the source. At the same time, the force is more evenly distributed when multiple surfaces are in contact during meshing, and the fit will not fail due to local wear. When the motor rotates forward or reverse, the tooth meshing can transmit the forward or reverse power synchronously. Furthermore, this transmission clutch device has no gear meshing gap and no triangular plate friction gap, resulting in a lower energy loss rate during power transmission.

The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.

[0024] Please see Figures 1 to 7 This embodiment provides a transmission clutch device 100, which includes a first half-clutch 10 and a second half-clutch 20. During use, the first half-clutch 10 is connected to the output shaft of the motor, and the second half-clutch 20 is mounted on the driven structural component. When transmission is required, the first half-clutch 10 and the second half-clutch 20 are engaged to achieve transmission connection. Figure 1 The status is shown; when transmission is not required, the transmission connection is disconnected by controlling the first half-clutch 10 and the second half-clutch 20 to separate. Figure 2 The status is displayed.

[0025] Specifically, the first half-clutch 10 has a first connecting hole 11 extending through its central axis, and a first engaging portion 12 is provided around the first connecting hole 11 on one side end face of the first half-clutch 10. The first engaging portion 12 is annular and has multiple first teeth 121 spaced along the annular interval. A first tooth groove 122 is formed between adjacent first teeth 121, and the first tooth groove 122 has a meshing surface that is arranged opposite to each other. The second half-clutch 20 has a second connecting hole 21 extending through its central axis, and a second engaging portion 22 is provided around the second connecting hole 21 on one side end face of the second half-clutch 20. The second engaging portion 22 is configured to be selectively disengaged from or engaged with the first engaging portion 12. The second engaging portion 22 is annular and has multiple second teeth 221 spaced along the annular interval. A second tooth groove 222 is formed between adjacent second teeth 221, and the second tooth groove 222 has a meshing surface that is arranged opposite to each other.

[0026] It should be noted that the projected outline of the first half-clutch 10 along the central axis is the same as that of the second half-clutch 20 along the central axis, and this projected outline is circular. The projected outlines of the second engagement portion 22 on both the first and second half-clutch 10 and the second half-clutch 20 along the central axis are also the same annular shape. This facilitates the engagement and transmission between the first half-clutch 10 and the second half-clutch 20. Furthermore, the projected outlines of the plurality of first teeth 121 on the first engagement portion 12 and the plurality of second teeth 221 on the second engagement portion 22 along the central axis are arc segments, and each of the first teeth 121 and second teeth 221... It has vertically arranged planes, and the adjacent planes of adjacent first pawls 121 form the meshing surface of the first tooth groove 122, and the adjacent planes of adjacent second pawls 221 form the meshing surface of the second tooth groove 222. When the first half-clutch 10 and the second half-clutch 20 are engaged, the first pawl 121 extends into the second tooth groove 222 and fits against the meshing surfaces of the two adjacent second pawls 221, and the second pawl 221 extends into the first tooth groove 122 and fits against the meshing surfaces of the two adjacent first pawls 121. Thus, when driven to rotate by the motor, the meshing process of the first half-clutch 10 and the second half-clutch 20 is smoother, reducing the mechanical impact and high-frequency vibration during gear meshing, and reducing noise from the source.

[0027] It should also be noted that the first connecting hole 11 is opened through the central axis of the first half clutch 10, and the second connecting hole 21 is opened through the central axis of the second half clutch 20. Since the first connecting hole 11 and the second connecting hole 21 are used to connect external components, and the first engaging part 12 is arranged around the first connecting hole 11 and the second engaging part 22 is arranged around the second connecting hole 21, when the first engaging part 12 and the second engaging part 22 are connected, the central axis of the first connecting hole 11 and the central axis of the second connecting hole 21 are collinear, thereby ensuring stability during the transmission process.

[0028] In the clutch device 100 provided in this embodiment, the first half-clutch 10 and the second half-clutch 20 are respectively provided with annular first engagement portions 12 and second engagement portions 22 on their corresponding end faces. The first engagement portions 12 and the second engagement portions 22 are respectively provided with a plurality of first teeth 121 and second teeth 221 spaced along an annular interval. A first tooth groove 122 and a second tooth groove 222 are formed between adjacent first teeth 121 and between adjacent second teeth 221, respectively. The first tooth groove 122 and the second tooth groove 222 have relatively opposite engagement surfaces. During the engagement of the first half-clutch 10 and the second half-clutch 20, the contact area between the teeth and the tooth groove is larger, and the engagement process is smoother. This reduces the mechanical impact and high-frequency vibration during gear engagement, thereby reducing noise at the source. At the same time, the force is more evenly distributed on multiple contact surfaces during engagement, preventing failure of the fit due to local wear. When the motor rotates forward or in reverse, the tooth meshing can synchronously transmit forward or reverse power. Furthermore, this transmission clutch device 100 has no gear meshing clearance and no triangular plate friction clearance, resulting in a lower energy loss rate during power transmission.

[0029] Please see Figures 3 to 5 In some embodiments, a boss 13 is provided on the end face of the first half clutch 10 away from the first engagement part 12. The first connecting hole 11 extends through to one side end face of the boss 13 to the end face of the first half clutch 10 near the first engagement part 12. At least one pin hole 131 communicating with the first connecting hole 11 is provided on the side wall of the boss 13. The pin hole 131 is used for positioning and fixing the first half clutch 10 during installation. A first keyway 111 is provided on the inner side wall of the first connecting hole 11 along its axial direction. At least one pin hole 131 communicates with the first keyway 111.

[0030] Specifically, the boss 13 is cylindrical and is arranged along the central axis of the first half-clutch 10. The first connecting hole 11 is opened inside the boss 13, the first keyway 111 is opened along the length of the first connecting hole 11, and the pin hole 131 is preferably opened along the radial direction of the boss 13, that is, the central axis of the pin hole 131 intersects the central axis of the first connecting hole 11. The arrangement of the boss 13, the first connecting hole 11, and the first keyway 111 facilitates the connection and fixation of the first half-clutch 10 with the output shaft of the motor. At the same time, the arrangement of the pin hole 131 facilitates the fixation of the key installed in the first keyway 111 by a pin.

[0031] Please see Figures 3 to 7In some embodiments, the diameter of the projected annular profile of the first engagement portion 12 along the axis of the first half-clutch 10 is equal to the diameter of the projected annular profile of the second engagement portion 22 along the axis of the second half-clutch 20; the distance between the opposite end faces of the first tooth groove 122 is equal to the distance between the opposite end faces of the second tooth pawl 221, and the distance between the opposite end faces of the second tooth groove 222 is equal to the distance between the opposite end faces of the first tooth pawl 121; thus, when the first engagement portion 12 and the second engagement portion 22 are connected, the uniformity of the force on the first half-clutch 10 and the second half-clutch 20 is ensured.

[0032] Optionally, the second half-clutch 20 is provided with a connecting hole 23 between the second engagement portion 22 and the second connecting hole 21, and multiple connecting holes 23 are spaced around the second connecting hole 21; the second half-clutch 20 is provided with at least two positioning holes 24 spaced between the second engagement portion 22 and the second connecting hole 21, and the positioning holes 24 are staggered from the connecting holes 23. Meanwhile, a second keyway 211 is provided on the inner sidewall of the second connecting hole 21. The second keyway 211 facilitates the connection and fixation of the second half-clutch 20. In this embodiment, it should be noted that... It is clear that by arranging the connecting holes 23 at intervals around the second connecting holes 21, multiple points on the surface of the second half-clutch 20 can be fixed, thereby ensuring the stability of the second half-clutch 20 during operation. At the same time, since the second meshing part 22 of the second half-clutch 20 is subjected to force during the meshing transmission process, and the connecting holes 23 are arranged between the second meshing part 22 and the second connecting holes 21 and are arranged at intervals, the force on the second meshing part 22 can be quickly transmitted through the connecting parts installed on the connecting holes 23, thereby improving the transmission efficiency.

[0033] Please see Figure 8 This embodiment also provides a blank trimming machine 1000, which includes a transmission clutch device 100, an upper aluminum mold base 200, a power motor 300, and a lifting cylinder 400 as described in any of the above embodiments. The output shaft of the lifting cylinder 400 is connected to the frame supporting the power motor 300 to drive the power motor 300 to move up and down. The power motor 300 is located below the upper aluminum mold base 200, and its output shaft is connected to a first half-clutch 10. A second half-clutch 20 is installed and fixed at the bottom of the upper aluminum mold base 200. The lifting cylinder 400 drives the first half-clutch 10 to rise and fall, thereby precisely controlling the engagement / disengagement of the first half-clutch 10 and the second half-clutch 20. The lifting stroke of the cylinder is precisely controlled by air pressure, which can avoid positioning deviation. At the same time, the tooth profile of the first half-clutch 10 and the second half-clutch 20 is not a point contact of a triangular plate, but a surface contact, which results in more uniform force distribution and prevents local wear caused by tooth backing during the engagement and disengagement process, thus avoiding engagement failure.
