Description

Technical Field

[0001] This invention belongs to the field of crimping manufacturing technology, specifically relating to a crimping machine mechanism. Background Technology

[0002] During the production process, parts need to be assembled into a single unit using a crimping process, while ensuring the product's pull-out force and airtightness. Furthermore, since each component has tolerances, force control must be employed to manage the equipment's operation during crimping to prevent damage to non-metallic parts and ensure product quality.

[0003] Currently, the industry uses conical crimping mechanisms, multi-hydraulic cylinder crimping mechanisms, and multi-servo electric cylinder crimping mechanisms for crimping.

[0004] The characteristics of a conical crimping mechanism are: good synchronization and high roundness consistency of the crimped product; however, due to the limited space of the conical surface, the crimping die stroke is insufficient, which may cause interference when picking up and placing workpieces in the production of special products. Therefore, it can only be adapted to manual operation, which is inefficient and cannot be used for automated production lines. The second drawback of the limited space of the mechanism is that it is impossible to install force sensors to control the operation of the equipment, making it difficult to control product quality.

[0005] Features of multi-hydraulic cylinder crimping mechanism: The stroke can be satisfied by selecting the right hydraulic cylinder. Due to sufficient space, it is easy to install force sensors. The crimping process can be controlled by force. However, due to the manufacturing precision differences of the multiple hydraulic cylinders themselves, the consistency differences of the multi-channel hydraulic pipeline system, and the objective defects of the hydraulic system, the synchronization of the crimping mold operation is poor. The roundness of the product after crimping cannot be effectively guaranteed, which affects the product quality.

[0006] The characteristics of multi-cylinder clamping mechanisms: The stroke can be satisfied by selecting servo cylinders. Due to sufficient space, force sensors are easily installed, and the clamping process can be controlled by force. However, servo cylinders themselves are expensive, and achieving multi-cylinder synchronization requires highly sophisticated electronic control, resulting in a particularly high overall cost. This significantly impacts the product's manufacturing cost. Summary of the Invention

[0007] In view of the shortcomings of the prior art, the purpose of this invention is to provide a crimping machine mechanism that solves the requirements of synchronization, large stroke, and force control required by the crimping process, ensures product quality, and is easy to automate the production line with low equipment cost.

[0008] To achieve the above and other related objectives, the present invention provides a crimping machine mechanism, comprising: a mounting panel and a multi-curve cam rotatably disposed between the mounting panel and the mounting panel, wherein the inner ring of the multi-curve cam forms a first track; a slide assembly slidably disposed on the mounting panel along the radial direction of the rotation center, wherein a first end of the slide assembly is provided with a first follower wheel tangent to the first track; the slide assembly is assembled such that when the multi-curve cam rotates, the slide assembly slides back and forth along the radial direction; wherein a crimping mold is provided at the second end of the slide assembly for locking parts.

[0009] According to a specific embodiment of the present invention, it further includes: a cam plate, which is fixedly mounted on the surface of the multi-curve cam, and a second track is formed on the side of the cam plate away from the rotation center, the second track being the same as the first track trajectory; the first end of the slide assembly is provided with an extension along the radial direction, and the end of the extension is provided with a second follower wheel tangent to the second track.

[0010] According to a specific embodiment of the present invention, the first track includes a large stroke section and a small stroke section, so that the slide assembly can switch between the following two working conditions: Working condition one, the clamping mold locks the part, at which time the first follower wheel is tangent to the small stroke section of the first track, and the slide assembly is close to the rotation center; Working condition two, the clamping mold opens, at which time the first follower wheel is tangent to the large stroke section of the first track, and the slide assembly is away from the rotation center.

[0011] According to a specific embodiment of the present invention, the slide assembly has a cavity inside for mounting a force sensor, and the force sensor is directly attached to the pressing mold.

[0012] According to a specific embodiment of the present invention, it further includes: a drive cam, which is rotatably engaged with the mounting panel, and the drive cam is fixedly connected to the multi-curve cam for driving the multi-curve cam to rotate.

[0013] According to a specific embodiment of the present invention, a rotation holding block is provided on the mounting panel along the rotational circumference, and the drive cam is mounted on the rotation holding block.

[0014] According to a specific embodiment of the present invention, the drive cam is seamlessly disposed between itself and the mounting panel.

[0015] According to a specific embodiment of the present invention, the drive cam is connected to a power source.

[0016] According to a specific embodiment of the present invention, the mounting panel is provided with a track, and the bottom of the slide assembly is provided with a sliding groove that slides in cooperation with the track.

[0017] According to a specific embodiment of the present invention, the multi-curve cam is made of steel through heat treatment.

[0018] The technical advantage of this invention lies in the fact that by setting a multi-curve cam with a track forming a large-stroke section and a small-stroke section on its inner ring, which cooperates with the first follower wheel to drive the slide assembly to slide back and forth, the locking and opening of the crimping mold is achieved. Further, a cam plate is set up, cooperating with the second follower wheel, so that the crimping machine mechanism is no longer limited to working on a horizontal plane, but can also be placed vertically for operation. Simultaneously, a force sensor is installed inside the slide assembly to effectively collect the force value of each crimping mold, realizing an intelligent working process. The multi-curve cam can be designed with different strokes and numbers of curves according to the crimping process requirements, reducing the load on the power source and achieving energy saving and emission reduction. Furthermore, the multi-curve cam must be made of high-quality steel and undergo heat treatment to ensure the service life of the mechanism; the cam machining process must ensure the consistency of each cam curve relative to the base circle, thereby ensuring consistency and synchronization during the crimping process.

[0028] When numerical ranges are given in the embodiments, it should be understood that, unless otherwise stated in the present invention, both endpoints of each numerical range and any value between the two endpoints may be selected. Unless otherwise defined, all technical and scientific terms used in this invention, as well as the prior art known to those skilled in the art and the description of this invention, may be implemented using any prior art methods, devices, and materials similar to or equivalent to those described, used, or made of materials in the embodiments of this invention.

[0029] Please see Figure 1-4As shown, a crimping machine mechanism includes: a mounting panel 10, which serves as a base to support the mounting of all parts; a multi-curve cam 20, rotatably disposed between the mounting panel 10, with a first track 21 formed on the inner ring of the multi-curve cam 20; and a slide assembly 30, slidably disposed on the mounting panel along the radial direction of the rotation center of the multi-curve cam 20, with a first follower wheel 311 at its first end 31 tangent to the first track 21. Specifically, in application, there is a certain friction between the first track 21 and the first follower wheel 311, allowing the first follower wheel 311 to roll along the first track 21. The slide assembly 30 is configured such that when the multi-curve cam 20 rotates, the first follower wheel 311 rolls along the inner ring of the first track 21, and the first track 21 has at least a concave-convex portion, thereby driving the slide assembly 30 to slide back and forth via the first follower wheel 311. Furthermore, in this embodiment, a clamping mold 321 is provided on the second end 32 of the slide assembly 30, and eight slide assemblies 30 are provided in the circumferential direction so that the clamping mold 321 can form a circle to lock the parts therein. Further, the number of slide assemblies 30 is not limited and can be set according to the actual size and shape of the clamping mold 321 to ensure it can lock the parts therein.

[0030] In one specific embodiment, the multi-curve cam 20 is further provided with a cam plate 40, which is fixedly mounted protruding from the surface of the multi-curve cam 20. Specifically, the side of the cam plate 40 near the rotation center is flush with the inner edge of the multi-curve cam 20. Further, the side of the cam plate 40 near the rotation center can be configured to have the same shape as the inner ring at the mounting location, so that one side is on the same plane, so that the sliding table assembly 30 does not restrict the sliding distance when sliding back and forth. At the same time, a second track is formed on the side of the cam plate 40 away from the rotation center, and the trajectory of the second track is set to be consistent with the first track 21. Correspondingly, the first end 31 of the sliding table assembly 30 forms an extension portion 312, which extends towards the cam plate 40. A second follower wheel 313 is provided on the extension portion 312 and is tangent to the second track. Specifically, in application, there is also a certain friction between the second track and the second follower wheel 313, allowing the second follower wheel 313 to roll along the second track. Since the second track follows the same trajectory as the first track 21, it does not affect the sliding of the slide assembly 30, but it frees the mounting panel 10 from being confined to a horizontally oriented working environment. Without the cam plate 40 and the second follower wheel 313, when the mounting panel is placed in a vertically oriented working environment, the slide assembly would slide due to its own weight, affecting normal operation. Because the second track of the cam plate 40 cooperates with the second follower wheel 313, the slide assembly 30 is no longer affected by gravity, providing traction to the slide assembly 30, allowing the mounting panel to function normally even when set in a vertical orientation.

[0031] In one specific embodiment, the first track 21 includes a large stroke section 211 and a small stroke section 212, allowing the slide assembly 30 to switch between two operating conditions: Condition 1, the clamping mold locks the part, in which case the first follower wheel is tangent to the small stroke section of the first track, and the slide assembly is close to the rotation center; Condition 2, the clamping mold opens, in which case the first follower wheel is tangent to the large stroke section of the first track, and the slide assembly is away from the rotation center. Specifically, in application, the large stroke section 211 is formed as a recess away from the rotation center, thereby making the small stroke section 212 relatively convex, thus creating a height difference, and the large stroke section 211 and the small stroke section 212 smoothly transition, allowing the slide assembly 30 to slide back and forth under the drive of the first follower wheel 311 and the second follower wheel 313 for locking and opening. Simultaneously, in this embodiment, a gap is formed at the rotation center for placing parts.

[0032] In one specific embodiment, it further includes a drive cam 50, which rotatably engages with the mounting panel 10 and is fixedly disposed at the same rotation center as the multi-curve cam 20, thereby driving the multi-curve cam 20 to rotate. Specifically, in application, the mounting panel 10 is provided with a rotation holding block 11 along the rotational circumference of the drive cam. In this embodiment, the rotation holding block 11 functions similarly to a rotary bearing, and the drive cam 50 is mounted on the rotation holding block 11 to achieve a rotatable connection. Furthermore, the drive cam 50 is seamlessly disposed with the mounting panel 10 to prevent mud and dust from splashing into it and damaging the device, affecting its operation. At the same time, the drive cam 50 is connected to a power source, and can be set to switch the working state of the crimping machine according to actual needs by setting a switch control or remote control.

[0033] In one specific embodiment, a cavity 33 is formed inside the slide assembly 30. A force sensor is installed inside the cavity 33 and is fitted into the clamping mold 321 to better collect the force condition of the clamping mold 321. When the power source is started, the drive cam 50 drives the multi-curve cam 20 to rotate, causing the slide assembly 30 to move towards the center of rotation, thereby locking the clamping mold 321 and clamping the product placed inside. When the force sensor senses a certain force value, the power source stops and reverses, driving the drive cam 50 to rotate in the opposite direction, causing the clamping mold 321 to open.

[0034] In one specific embodiment, the mounting panel 10 is provided with a raised track 12, and the bottom of the slide assembly 30 is formed with a corresponding sliding groove 34, so as to slide in cooperation with the track, allowing the slide assembly 30 to slide back and forth along the track 12.

[0035] In this embodiment, the multi-curve cam 20 can be designed with different formations and curve numbers according to the crimping process requirements. The first track 21 of the multi-curve cam 20 can be set with a larger forming section when the crimping machine is open and a smaller forming section when the crimping machine is locked, thereby reducing the load on the power source and achieving energy saving and emission reduction. Simultaneously, the multi-curve cam 20 must be made of high-quality steel and undergo heat treatment to ensure the service life of the mechanism. Furthermore, the processing technology must ensure the consistency of each cam curve relative to the base circle, thereby ensuring consistency and synchronization during the crimping process. The cam plate must be designed to coincide with the multi-curve cam to ensure the stability of the mechanism during operation.

[0036] It should be noted that the embodiments provided in this application are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present invention.

[0037] In summary, the technical advantages of this invention lie in the fact that by setting a multi-curve cam with a track forming a large-stroke section and a small-stroke section on its inner ring, which cooperates with the first follower wheel to drive the slide assembly to slide back and forth, the locking and opening of the crimping mold is achieved. Further, by setting a cam plate, which cooperates with the second follower wheel, the crimping machine mechanism is no longer limited to working on a horizontal plane, but can also be placed vertically for operation. Simultaneously, a force sensor is installed inside the slide assembly to effectively collect the force value of each crimping mold, achieving an intelligent working process. The multi-curve cam can be designed with different strokes and numbers of curves according to the crimping process requirements, reducing the load on the power source and achieving energy saving and emission reduction. Furthermore, the multi-curve cam must be made of high-quality steel and undergo heat treatment to ensure the service life of the mechanism; the cam machining process must ensure the consistency of each cam curve relative to the base circle, thereby ensuring consistency and synchronization during the crimping process.
