Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bionic bait processing, and particularly relates to a driving assembly and a clamping device for precise joint driving. BACKGROUND

[0002] Bionic bait refers to artificial bait that imitates the behavior and appearance of fish, and is used for fishing. By simulating the appearance, swimming mode, smell and taste of fish, bionic bait can attract the attention of fish and make them bite the bait. The bionic bait is usually made of synthetic materials such as silica gel, rubber or plastic. The bionic bait has a fish hook and a hanging chain at two ends, and the hanging chain is used to install the bionic bait.

[0003] During the manufacturing process of the bionic bait, a spraying operation is needed to achieve a realistic effect. Before spraying, the bionic bait needs to be clamped and fixed. In the prior art, in order to avoid the situation that the surface of the bionic bait is blocked and the spraying is not in place during the spraying process, a clamping device is usually used to clamp and fix the bionic bait. For example, in the patent document with the application number 202322462962.6, a clamping device for bionic bait is disclosed, and it is specifically disclosed that the bionic bait is clamped by a top clamping assembly and a bottom clamping assembly. The top clamping assembly includes a top rotating support, and the top rotating support has a first driving motor. The first driving motor provides power for the first meshing gear set, so that the first meshing gear set is driven to rotate under the driving action of the first driving motor, the transmission gear is driven to rotate under the meshing rotation, and the hanging chain is driven to rotate, so that the bionic bait body can rotate. At this time, the bionic bait body is fully sprayed by an external spraying device to ensure the spraying effect of the bionic bait body. Although this scheme can ensure the spraying effect of the bionic bait body, the scheme needs to set a motor on each side of the clamp, and the motor and the transmission device of the clamp are always in engagement, which increases the complexity of the structure and makes it difficult to apply to the assembly line for batch processing.

[0004] Therefore, there is an urgent need for a driving assembly and a clamping device with simple structure and capable of being applied to the assembly line for batch processing. Practical new type content

It should be noted that unless otherwise specified and limited, if the terms "provided", "connected", "connected" appear, they should be understood in a broad sense, for example, they can be fixedly connected, or can be detachably connected, or integrally connected; can be mechanically connected, can be directly connected, or indirectly connected through an intermediate medium, can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood specifically.

[0034] As shown in Figures 1 to 4 , a clamping device with precise engagement driving includes a driving device 20 and a clamp 1, the driving device 20 and / or the clamp 1 are connected with a translational driving member of an external device, under the action of the translational driving member, the driving device 20 and the clamp 1 are displaced to an engagement or separation state;

[0035] In some preferred embodiments, as shown in Figure 1 , Figure 2 , the clamp 1 includes a clamp frame 11, a transmission device 12, and a fish hook clamping assembly 13, the fish hook clamping assembly 13 is connected with the clamp frame 11 through the transmission device 12, an input end of the transmission device 12 is provided with a clutch 121, an outer end face of the clutch 121 is provided with an access hole 1211, the access hole 1211 is used for matched connection with an output end of the driving device 20;

[0036] In some preferred embodiments, the output end of the driving device 20 is flexibly engaged with the clutch 121, and the output end of the driving device 20 is provided with a column shaft 2011 engaged with the access hole 1211, under the action of the translational driving member, the driving device 20 is displaced towards or away from the clutch 121, to realize the engagement or separation action of the column shaft 2011 and the access hole 1211.

[0037] In some preferred embodiments, the clamping assembly 13 comprises a plurality of clamping sets arranged along the x-axis direction, and each clamping set is driven to rotate synchronously by the transmission device 12. Any clamping set comprises two clamping units arranged oppositely along the y-axis direction, and the two clamping units are respectively used for clamping the head and tail ends of the artificial bait.

[0038] In some preferred embodiments, the transmission device 12 comprises a first synchronous transmission set located at one side of the head end of the artificial bait, a second synchronous transmission set located at one side of the tail end of the artificial bait, and a first driving shaft connecting the first synchronous transmission set and the second synchronous transmission set. The first synchronous transmission set and the second synchronous transmission set each comprise a plurality of driven wheels. The driven wheels arranged oppositely in the two transmission sets correspond to each other, and are coaxially connected with the corresponding clamping units. The adjacent driven wheels are connected in transmission by transmission belts or transmission chains to realize synchronous rotation.

[0039] When the driving device 20 is connected with the clutch 121, the driving device 20 drives the transmission device 12 to rotate through the clutch 121, and in turn drives the fish hook clamping assembly 13 to rotate, so that the bionic fish bait body on the fish hook clamping assembly 13 can rotate. At this time, the bionic fish bait body is fully sprayed by the external spraying equipment, and the spraying effect of the bionic fish bait body is ensured.

[0040] In some preferred embodiments, the column shaft 2011 is arranged at the rotation axis of the output end of the driving device 20. The column shaft 2011 is a prism, and correspondingly, the access hole 1211 is arranged at the center of the clutch 121, and the hole shape matches the outer shape of the column shaft 2011. The access hole 1211 is used for driving the clutch 121 to rotate by inserting the column shaft 2011 into the access hole 1211, and in turn driving the transmission device 12 to rotate.

[0041] However, in actual application, due to batch processing, the driving device 20 and the clutch 121 will frequently engage or separate. After each separation, it is difficult to ensure that the position angle of the prismatic column shaft 2011 and the access hole 1211 is consistent. This leads to difficulty in engagement due to position angle deviation during the engagement process. Therefore, the applicant further optimizes the above scheme.

[0042] In some preferred embodiments, as shown in FIG. 10, the column shaft 2011 is provided with a plurality of protrusions 2012 arranged along the circumferential direction of the column shaft 2011. The access hole 1211 is provided with a plurality of protrusions 1212 arranged along the circumferential direction of the access hole 1211. The protrusions 2012 and the protrusions 1212 are arranged in a one-to-one correspondence, and the protrusions 2012 and the protrusions 1212 are arranged in a one-to-one correspondence. Figure 3As shown, the column shaft 2011 is an eccentrically arranged cylindrical shaft. Eccentricity means that the axis of the column shaft 2011 is not coaxial with the rotation axis of the drive device 20. The number of column shafts 2011 is at least two. At least two eccentric column shafts 2011 are connected to one side of the frustum 2012 and are centrally symmetrical about the center of the frustum 2012. The center of the other side of the frustum 2012 is connected to the center of the rotation axis of the drive device 20, so that when the rotation axis of the drive device 20 rotates, the frustum 2012 can drive at least two column shafts 2011 to rotate in a circle around the center of the rotation axis.

[0043] Accordingly, a number of access holes 1211 are provided, and the number of access holes 1211 are circumferentially distributed along the center of the clutch 121. The position of the column shaft 2011 corresponds to any access hole 1211, so as to realize the quick engagement of the column shaft 2011 with the access hole 1211 and the stable drive of the clutch 121 to rotate.

[0044] In some preferred embodiments, the end of the column shaft 2011 is bullet-shaped for quick engagement, so that even if there is a deviation in the engagement position between the column shaft 2011 and the access hole 1211, it can still engage with the access hole 1211 at different positions or angles to adapt to different production needs.

[0045] In some preferred embodiments, in order to avoid rigid collisions of the column shaft 2011 during the engagement process due to misalignment of the engagement position, the applicant has optimized the structure of the drive device 20.

[0046] Specifically, such as Figure 4 As shown, the driving device 20 includes a drive motor 201, a first fixed seat 202, an elastic member 203, and a second fixed seat 204. The column shaft 2011 is disposed at the output end of the drive motor 201. The drive motor 201 is connected to the first fixed seat 202. The first fixed seat 202 is connected to the second fixed seat 204 through the elastic member 203, so that the clutch 121 and the drive motor 201 will not be damaged by impact force during the engagement process, thus achieving flexible engagement.

[0047] In some preferred embodiments, the elastic component 203 can be a spring, a leaf spring, a rubber spring, a shock-absorbing pad, or a structure in which multiple components work together to have elasticity. The specific structure is not further limited here.

[0048] In some preferred embodiments, the driving device 20 further comprises a coupling 205 connected to the output shaft of the driving motor 201, the output shaft of the driving motor 201 being the rotating shaft of the driving device 20, the motor output shaft of the driving motor 201 being connected with the circular table 2012 through the coupling 205, for realizing coaxial connection of the driving motor 201 output shaft and the circular table 2012.

[0049] The specific embodiments of the present application are described above in detail, and for those skilled in the technical field, some improvements and modifications can be made to the present application without departing from the principles of the present application, and these improvements and modifications also belong to the protection scope of the claims of the present application.
