Description

Technical Field

[0001] The present application relates to the technical field of processing equipment, and in particular to a closing device. Background Art

[0002] The goal of closing the opening is similar to the solder cup jack. One of the important contact parts of the solder cup jack connector, the jack slot can be divided into single-petal, double-petal, triple-petal, quad-petal, and six-petal according to the number of its reeds. The jack needs to be closed at a certain angle after machining by the Swiss machine before it can be used. If the bending angle of each reed is unreasonable after closing, it will affect the quality of the connector. The most affected part is the contact resistance in the electrical performance of the connector, which will cause the interruption of signal transmission during the connection process and make the connector unusable.

[0003] At present, the way to close the target parts such as welding cup sockets that need to be closed is mostly to manually bend the reeds of the welding cup sockets one by one using tools such as flat-nose pliers to achieve the closing. However, this method easily causes uneven bending of the reeds of the sockets, inaccurate control of the closing force, and the insertion and extraction force does not meet the requirements.

[0004] In other words, the current method of closing the ends of target parts that need to be closed is not of high enough process quality. Summary of the invention

[0005] The purpose of the present application is to provide a closing device, which can improve the consistency, uniformity and stability of closing a target part, thereby improving the process quality of closing the target part.

[0006] The present application provides a closing device for closing the opening of a target part; the device includes a base, a turntable and a slider; the turntable is rotatably arranged on the base; a plurality of slide grooves are arranged on a side of the base facing the turntable, and a receiving space is provided in the middle for receiving the target part; the length direction of the slide groove is consistent with any radial direction of the turntable and is connected with the receiving space; a guide groove is arranged on the turntable, and the two ends of the guide groove are neither located in the same radial direction of the turntable nor in the same circumferential direction of the turntable; the slider includes a sliding part and a guiding part; the sliding part is slidably arranged in the slide groove, and the guide part is located in the guide groove; the turntable is configured to drive the slider to move toward the receiving space by rotation to squeeze the opening of the target part, or drive the slider to move back to the receiving space.

[0007] The above-mentioned closing device rotates the turntable and, under the guidance of the guide groove on the turntable, drives several sliders to approach or move away from the accommodation space at the same time, thereby realizing the simultaneous extrusion of each spring leaf on the target part, and the extrusion amplitude is consistent, and finally improving the uniformity of closing the same target part. In addition, whether the turntable is driven to rotate automatically or manually, its rotation angle is relatively easy to control, and then by controlling the rotation angle of the turntable, the amplitude of the slider extruding the spring leaf on each target part can be made consistent. Thereby improving the consistency and stability of closing the target part. Finally, the process quality of closing the target part is improved.

[0008] Optionally, the guide groove comprises an arc-shaped guide groove; and the rotation center axis of the turntable is located on the arc-shaped inner side of the arc-shaped guide groove.

[0009] Compared with other types of guide grooves such as linear guide grooves, the arc-shaped guide grooves of the above-mentioned closing device make the slider move more uniformly when the turntable rotates and drives the slider to move in the radial direction of the turntable, and the turntable rotates at a constant speed, so that the movement of the slider is more easily controlled, that is, the controllability of the closing device is improved.

[0010] Optionally, the device also includes a positioning member; a through hole is provided in the middle of the turntable; the center of the through hole is located at the rotation center axis of the turntable; the positioning member has a sleeve portion and a flange portion; the sleeve portion is connected to the base; the through hole of the turntable is sleeved in the sleeve portion, and the flange portion is in contact with the turntable.

[0011] The above-mentioned closing device limits the movement of the turntable in its radial direction by sleeve-fitting the turntable on the sleeve-fitting part of the positioning member. The movement of the turntable on the rotating central axis is limited by the fit between the flange part of the positioning member and the turntable. Finally, the stability of the turntable during rotation is improved.

[0012] Optionally, a first accommodating portion is provided on the inner wall of the through hole; a first rolling member is provided in the first accommodating portion; the first rolling member contacts the first accommodating portion and the sleeve portion respectively, and rolls on the sleeve accommodating portion when the turntable rotates.

[0013] The above-mentioned closing device is provided with a first rolling element at the contact position between the rotating disk and the sleeve part, so that during the rotation of the rotating disk, the sliding friction between the sleeve part and the rotating disk is changed into rolling friction, thereby reducing the friction between the rotating disk and the sleeve part and improving the smoothness of the rotating disk rotation.

[0014] Optionally, a second accommodating portion is further provided on a side of the base facing the turntable; a second rolling member is provided in the second accommodating portion; the second rolling member is in contact with the second accommodating portion and the turntable respectively, and rolls on the turntable when the turntable rotates.

[0015] The above-mentioned closing device, by arranging a second rolling element at the contact position between the turntable and the base, also makes the sliding friction between the turntable and the base turn into rolling friction during the rotation of the turntable, thereby reducing the friction between the turntable and the base and further improving the smoothness of the turntable rotation.

[0016] Optionally, the device also includes a limiting plate; the sliding portion has a step on one side facing the bottom of the slide groove, and the step surface faces the accommodating space; the limiting plate is located in the accommodating space of the base; the edge of the limiting plate is configured to abut against the step surface when the slider slides to a specific position toward the accommodating space.

[0017] The above-mentioned closing device, through the abutment of the edge of the limiting disk against the step surface on the slider, makes the slider abut against the limiting disk when it moves to a specific position, thereby limiting the movement of the slider. Correspondingly, the rotation of the turntable is also limited. When closing multiple target parts, each target part is limited to the same position by the limiting disk, so that the degree of closing of each target part is consistent. The consistency of closing multiple target parts is further improved, and the difficulty of closing multiple target parts consistently is simplified.

[0018] Optionally, the limiting plate includes a plate body and an annular limiting portion; the annular limiting portion extends from the edge of the plate body toward the turntable; the annular limiting portion is provided with an adjusting member corresponding to the position of at least one slider; the adjusting member extends from the inner side of the annular limiting portion to the outer side of the annular limiting portion, and is configured to extend and retract in the annular limiting portion so as to abut against the step surface when the slider slides to a specific position toward the accommodating space.

[0019] The above-mentioned closing device is provided with an adjusting member similar to a bolt on the annular limiting portion of the limiting plate, and the adjusting member has different extension and contraction degrees on the annular limiting portion to abut against the slider moved to different positions, thereby limiting the movement of the slider. Thus, the degree of closing of the target part by the closing device is adjusted by adjusting the adjusting member. The convenience of using the closing device is improved, and the consistency of closing of multiple target parts by the closing device is further improved.

[0020] Optionally, the slider is used to extrude the extrusion surface of the target part; the extrusion surface has an upper end facing the turntable and a lower end facing away from the turntable; from the upper end of the extrusion surface to the lower end of the extrusion surface, it gradually moves away from the rotation center axis of the turntable.

[0021] The above-mentioned closing device is used to extrude the opening of the target part through the inclined extrusion surface, so that during the closing process, the extrusion surface can better fit the opening of the target part, thereby playing a role in protecting the target part.

[0022] Optionally, the sliding portion has a sliding surface facing the inner wall of the sliding groove; and a recessed surface recessed away from the inner wall of the sliding groove is provided on the sliding surface.

[0023] In the above-mentioned closing device, when no recessed surface is provided on the sliding surface facing the inner wall of the chute, it usually means that the entire sliding surface will contact the inner wall of the chute. However, by providing the recessed surface on the sliding surface, the contact area between the sliding surface and the inner wall of the chute is correspondingly reduced, thereby reducing the friction between the sliding part and the chute. Finally, the smoothness of the movement of the slider in the chute is improved.

[0024] Optionally, the device further comprises a handle; one end of the handle is connected to the edge of the turntable; and the length direction of the handle is consistent with any radial direction of the turntable.

[0025] The above-mentioned closing device, by connecting a handle to the turntable, realizes manual driving of the turntable and increases the force arm for rotating the turntable, thereby making the closing operation of the turntable more labor-saving and simplifying the structure of the closing device.

[0026] In summary, the closing device provided by the present application drives several sliders to approach or move away from the accommodation space at the same time by rotating the turntable and under the guidance of the guide groove on the turntable, thereby realizing the simultaneous extrusion of each spring leaf on the target part, and the extrusion amplitude is consistent, and finally improving the uniformity of closing the same target part. The turntable is sleeved on the sleeve part of the positioning member, and the movement of the turntable in its radial direction is limited. The movement of the turntable on the rotation center axis is limited by the fit between the flange part of the positioning member and the turntable. Finally, the stability of the turntable during rotation is improved. By setting a first rolling member at the contact position between the turntable and the sleeve part, and setting a second rolling member at the contact position between the turntable and the base, the smoothness of the rotation of the turntable is improved. By setting an adjusting member similar to a bolt on the annular limit part of the limit plate, the convenience of use of the closing device is improved, and the consistency of the closing of the closing device on multiple target parts is further improved. By setting a concave surface on the sliding surface, the contact area between the sliding surface and the inner wall of the slide groove is correspondingly reduced, thereby reducing the friction between the sliding part and the slide groove.

DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0047] Please refer to Figures 1 to 3 , Figure 1 is a perspective view of the target part 200; Figure 2 This is a first stereoscopic view of the closing device 100 provided in an embodiment of the present application; Figure 3 : is an exploded view of the closing device 100 provided in an embodiment of the present application. The closing device 100 provided in an embodiment of the present application can be used to close the opening of the target part 200. The closing device 100 may include a base 110, a turntable 120 and a slider 130. The turntable 120 is rotatably arranged on the base 110. A plurality of slide grooves 111 may be arranged on the side of the base 110 facing the turntable 120, and a receiving space for receiving the target part 200 may be provided in the middle. The length direction of the slide groove 111 may be consistent with any radial direction of the turntable 120, and may be connected to the receiving space. A guide groove 121 may be arranged on the turntable 120, and the two ends of the guide groove 121 may not be located in the same radial direction of the turntable 120, nor in the same circumferential direction of the turntable 120. The slider 130 may include a sliding portion 131 and a guiding portion 132. The sliding portion 131 may be slidably arranged in the slide groove 111, and the guiding portion 132 may be located in the guide groove 121. The turntable 120 may be configured to drive the slider 130 to move toward the accommodation space by rotating to press the opening of the target part 200 , or to drive the slider 130 to move away from the accommodation space.

[0048] like Figure 1 As shown, the target part 200 includes a target part 200 body and an opening 210. Six cuts can be cut on the opening 210, so that the opening 210 presents a six-petal spring.

[0049] The rotatable connection between the turntable 120 and the base 110 can be achieved by providing a rotating pin on the base 110 or the turntable 120, or by providing a ball bearing structure similar to a rotating bearing between the turntable 120 and the base 110. The length direction of the plurality of slide grooves 111 provided on the base 110 can be distributed along the radial direction of the turntable 120, so that the slider 130 can move along the radial direction of the turntable 120.

[0050] It should be understood that the number of the slide grooves 111 , the number of the sliders 130 , and the number of the guide grooves 121 are usually equal.

[0051] The guide groove 121 on the rotating disk 120 can be linear or curved. Since the two ends of the guide groove 121 are neither located in the same radial direction of the rotating disk 120 nor in the same circumferential direction of the rotating disk 120, during the rotation of the rotating disk 120, the contact position between the guide groove 121 and the guide portion 132 will be close to or away from the accommodation space. Thus, the slider 130 is moved along the rotating disk 120.

[0052] In the process of closing the mouth using the closing device 100 provided in the embodiment of the present application, the opening 210 of the target part 200 can be placed in the accommodation space. By rotating the turntable 120, the slider 130 moves toward the accommodation space, so that the slider 130 squeezes the opening 210 of the target part 200 to close the mouth of the target part 200. After the closing is completed, the turntable 120 is rotated in the opposite direction to return the slider 130 to the initial position. Then, the next target part 200 to be closed is replaced.

[0053] In the above implementation process, by rotating the turntable 120 and under the guidance of the guide groove 121 on the turntable 120, a plurality of sliders 130 are driven to approach or move away from the accommodation space at the same time, thereby achieving the simultaneous extrusion of each spring leaf on the target part 200, and the extrusion amplitude is consistent, and finally improving the uniformity of closing the same target part 200. In addition, whether the turntable 120 is driven to rotate automatically or manually, its rotation angle is relatively easy to control, and then by controlling the rotation angle of the turntable 120, the amplitude of the extrusion of the spring leaf on each target part 200 by the slider 130 is consistent. Thereby improving the consistency and stability of closing the target part 200. Finally, the process quality of closing the target part 200 is improved.

[0054] Please refer to Figure 4 , Figure 4 1 is a perspective view of the turntable 120 in the closing device 100 provided in the embodiment of the present application. In some optional embodiments, the guide groove 121 may include an arc-shaped guide groove 121. The rotation center axis of the turntable 120 may be located inside the arc of the arc-shaped guide groove 121.

[0055] In the above implementation process, compared with other types of guide grooves 121 such as linear guide grooves 121, when the turntable 120 rotates and drives the slider 130 to move along the radial direction of the turntable 120, the movement of the slider 130 also tends to be more uniform when the turntable 120 rotates at a constant speed. This makes it easier to control the movement of the slider 130, that is, to improve the controllability of the closing device 100.

[0056] Please refer to Figure 5 and Figure 6 , Figure 5 This is a second stereoscopic view of the closing device 100 provided in the embodiment of the present application; Figure 6 yes Figure 5 Cross-sectional view at AA in the middle. In some optional embodiments, the closing device 100 provided in the embodiment of the present application may also include a positioning member 140. The middle of the turntable 120 may have a through hole. The center of the through hole may be located at the rotation center axis of the turntable 120. The positioning member 140 may have a sleeve portion 141 and a flange portion 142. The sleeve portion 141 may be connected to the base 110. The through hole of the turntable 120 may be sleeved on the sleeve portion 141, and the flange portion 142 may fit the turntable 120.

[0057] The connection between the sleeve portion 141 of the positioning member 140 and the base 110 can be bolted, or can be hard-connected by welding, clamping, etc. The through hole of the turntable 120 is sleeved on the sleeve portion 141, so that the sleeve portion 141 is equivalent to a rotating pin that realizes the rotatable connection between the turntable 120 and the base 110.

[0058] In the above implementation process, the radial movement of the turntable 120 is limited by the turntable 120 being sleeved on the sleeve portion 141 of the positioning member 140. The movement of the turntable 120 on the rotation center axis is limited by the fit between the flange portion 142 of the positioning member 140 and the turntable 120. Finally, the stability of the turntable 120 during the rotation process is improved.

[0059] Please continue to refer to Figures 4 to 6 In some optional embodiments, the inner wall of the through hole may be provided with a first accommodating portion 122. A first rolling member 123 may be provided in the first accommodating portion 122. The first rolling member 123 may contact the first accommodating portion 122 and the sleeve portion 141 respectively, and may roll on the sleeve accommodating portion when the rotating disk 120 rotates.

[0060] The first rolling element 123 may be a ball or a cylindrical roller.

[0061] In the above implementation process, the first rolling member 123 is arranged at the contact position between the rotating disk 120 and the sleeve portion 141, so that during the rotation of the rotating disk 120, the sliding friction between the sleeve portion 141 is converted into rolling friction, thereby reducing the friction between the rotating disk 120 and the sleeve portion 141 and improving the smoothness of the rotation of the rotating disk 120.

[0062] Please refer to Figure 7 , Figure 7 yes Figure 5 In some optional embodiments, the base 110 may be provided with a second accommodating portion 112 on one side facing the turntable 120. A second rolling member 113 may be provided in the second accommodating portion 112. The second rolling member 113 may be in contact with the second accommodating portion 112 and the turntable 120, respectively, and may roll on the turntable 120 when the turntable 120 rotates.

[0063] The second rolling element 113 can also be a ball or a cylindrical roller.

[0064] In the above implementation process, by arranging the second rolling member 113 at the contact position between the rotating disk 120 and the base 110, the sliding friction between the rotating disk 120 and the base 110 is also changed into rolling friction during the rotating process of the rotating disk 120. Thus, the friction between the rotating disk 120 and the base 110 is reduced, and the smoothness of the rotation of the rotating disk 120 is further improved.

[0065] Please refer to Figures 8 to 10 , Figure 8 This is a third stereoscopic view of the closing device 100 provided in the embodiment of the present application; Fig. 9 yes Figure 5 Sectional view at CC; Fig.10 : is a three-dimensional diagram of the limiting plate 150 in the closing device 100 provided in the embodiment of the present application. In some optional embodiments, the closing device 100 provided in the embodiment of the present application may also include a limiting plate 150. The side of the sliding portion 131 facing the bottom of the slide groove 111 may have a step, and the step surface 133 of the step may face the accommodation space. The limiting plate 150 may be located in the accommodation space of the base 110. The edge of the limiting plate 150 may be configured to abut against the step surface 133 when the slider 130 slides to a specific position toward the accommodation space.

[0066] The step surface 133 may be vertical, that is, parallel to the rotation center axis of the turntable 120 , and the step surface 133 may also have a certain inclination compared to the rotation center axis of the turntable 120 .

[0067] The limiting plate 150 can be connected to the base 110 by bolts, welding, clamping, etc. The setting height of the limiting plate 150 can be adapted to the height of the step surface 133, for example: the height of the upper edge of the step surface 133 is greater than the height of the edge of the limiting plate 150, and the height of the lower edge of the step surface 133 is less than the height of the edge of the limiting plate 150.

[0068] In the above implementation process, the edge of the limiting plate 150 abuts against the step surface 133 on the slider 130, so that when the slider 130 moves to a specific position, it is abutted by the limiting plate 150, and the movement of the slider 130 is restricted. Accordingly, the rotation of the turntable 120 is also restricted. When the closing operation is performed on multiple target parts 200, each target part 200 is limited by the limiting plate 150 to limit the movement of the slider 130 to the same position, so that the degree of closing of each target part 200 is consistent. The consistency of closing of multiple target parts 200 is further improved, and the difficulty of closing multiple target parts 200 in a consistent manner is also simplified.

[0069] Please continue to refer to Figures 8 to 10 In some optional embodiments, the limiting disk 150 may include a disk body 151 and an annular limiting portion 152. The annular limiting portion 152 may extend from the edge of the disk body 151 toward the turntable 120. An adjusting member 153 may be provided at a position of the annular limiting portion 152 corresponding to at least one slider 130. The adjusting member 153 may pass from the inner side of the annular limiting portion 152 to the outer side of the annular limiting portion 152, and may be configured to be retracted in the annular limiting portion 152, so as to abut against the step surface 133 when the slider 130 slides to a specific position toward the accommodation space.

[0070] That is to say, on the limiting plate 150, there is a certain space inside the annular limiting portion 152, and the space is used for the adjusting member 153 to extend and retract in the annular limiting portion 152. The adjusting member 153 may be a bolt.

[0071] In the process of operating the closing device 100 to close the target part 200, the position of the adjusting member 153 can be adjusted according to actual needs. For example, when the degree of closing of the target part 200 is relatively small, the part of the adjusting member 153 exposed to the annular limiting portion 152 can be lengthened, that is, the displacement of the adjusting member 153 toward the slider 130 is a little greater. Then, in the process of the slider 130 squeezing the opening 210 of the target part 200 by moving, it can abut the step surface 133 of the slider 130 relatively in advance, thereby limiting the further movement of the slider 130 to squeeze the opening of the target part 200.

[0072] In the above implementation process, an adjusting member 153 similar to a bolt is provided on the annular limiting portion 152 of the limiting plate 150, and the adjusting member 153 has different extension degrees on the annular limiting portion 152 to abut against the slider 130 moved to different positions, thereby limiting the movement of the slider 130. Thus, the degree of closing of the target part 200 by the closing device 100 is adjusted by adjusting the adjusting member 153. The convenience of use of the closing device 100 is improved, and the consistency of closing of multiple target parts 200 by the closing device 100 is further improved.

[0073] Please refer to Fig.11 , Fig.11 1 is a three-dimensional diagram of a slider 130 in a closing device 100 provided in an embodiment of the present application. In some optional embodiments, the slider 130 can be used to extrude an extrusion surface 134 of a target part 200. The extrusion surface 134 can have an upper end facing the turntable 120 and a lower end facing away from the turntable 120. From the upper end of the extrusion surface 134 to the lower end of the extrusion surface 134, it can gradually move away from the rotation center axis of the turntable 120.

[0074] That is, the extrusion surface 134 is inclined relative to the rotation center axis. When the extrusion surface 134 extrudes the spring leaf of the target part 200, the spring leaf usually changes from a vertical state to an inclined state, so that the contact between the spring leaf and the extrusion surface 134 can be changed from point contact to surface contact.

[0075] In the above implementation process, the inclined extrusion surface 134 is used to extrude the opening 210 of the target part 200, so that during the closing process, the extrusion surface 134 can better fit the opening 210 of the target part 200, thereby protecting the target part 200.

[0076] Please continue to refer to Fig.11 In some optional embodiments, the sliding portion 131 may have a sliding surface 1311 facing the inner wall of the sliding groove 111. The sliding surface 1311 may be provided with a concave surface 135 that is concave away from the inner wall of the sliding groove.

[0077] Taking the sliding part 131 as a quadrangular prism as an example, the sliding block 130 may face the inner wall of the chute 111 on three side surfaces of the quadrangular prism, that is, one side surface facing the bottom of the chute 111 and two side surfaces adjacent to the side surface. The recessed surface 135 may be disposed on these three side surfaces.

[0078] In the above implementation process, when the recessed surface 135 is not provided on the sliding surface 1311 facing the inner wall of the slide groove 111, it usually means that the entire sliding surface 1311 will contact the inner wall of the slide groove 111. However, by providing the recessed surface 135 on the sliding surface 1311, the contact area between the sliding surface 1311 and the inner wall of the slide groove 111 is correspondingly reduced, thereby reducing the friction between the sliding part 131 and the slide groove 111. Finally, the smoothness of the movement of the slider 130 in the slide groove 111 is improved.

[0079] Please refer to Fig.12 , Fig.12 This is a fourth stereogram of the closing device 100 provided in the embodiment of the present application. In some optional embodiments, the closing device 100 may further include a handle 160. One end of the handle 160 is closed and connected to the edge of the rotating disk 120. The length direction of the handle 160 is consistent with any radial direction of the rotating disk 120.

[0080] A threaded hole may be provided on the edge of the rotating disk 120 , and a corresponding external thread may be provided on one end of the handle 160 for connecting with the rotating disk 120 , so as to realize the threaded connection between the handle 160 and the rotating disk 120 .

[0081] Optionally, a workbench 170 may be configured for the closing device 100 , and the base 110 may be disposed on the workbench 170 .

[0082] In the above implementation process, by connecting the handle 160 to the turntable 120, the turntable 120 is manually driven, and the force arm for rotating the turntable 120 is increased, so that the closing operation of the turntable 120 is more labor-saving. In addition, the structure of the closing device 100 is simplified.

[0083] In summary, the closing device 100 provided in each embodiment of the present application drives a plurality of sliders 130 to approach or move away from the accommodation space at the same time by rotating the turntable 120 and under the guidance of the guide groove 121 on the turntable 120, thereby realizing the simultaneous extrusion of each spring leaf on the target part 200, and the extrusion amplitude is consistent, and finally improving the uniformity of closing the same target part 200. The turntable 120 is sleeved on the sleeve portion 141 of the positioning member 140, and the movement of the turntable 120 in its radial direction is limited. The movement of the turntable 120 on the rotation center axis is limited by the fit between the flange portion 142 of the positioning member 140 and the turntable 120. Finally, the stability of the turntable 120 during the rotation process is improved. The first rolling member 123 is arranged at the contact position between the turntable 120 and the sleeve portion 141, and the second rolling member 113 is arranged at the contact position between the turntable 120 and the base 110, so as to improve the smoothness of the rotation of the turntable 120. By providing an adjusting member 153 similar to a bolt on the annular limiting portion 152 of the limiting plate 150, the convenience of use of the closing device 100 is improved, and the consistency of the closing device 100 closing multiple target parts 200 is further improved. By providing a concave surface 135 on the sliding surface 1311, the contact area between the sliding surface 1311 and the inner wall of the slide groove 111 is correspondingly reduced, thereby reducing the friction between the sliding portion 131 and the slide groove 111.

[0084] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
