Description

Technical Field

[0001] The invention relates to the technical field of assembly clamping jaws of cable terminals, and in particular to an elastomer-based single-drive dual-control assembly clamping device and a clamping method. Background Art

[0002] In the automated assembly process, cable assembly is a very special type of assembly method. Different from the common rigid body assembly, the cable structure is mostly in the form of "upper flexible harness + middle rigid flange + lower elastic pin". During assembly, it is necessary to avoid the upper harness, clamp the rigid flange, and perform the elastic pin downward pressure matching action. There are high requirements for the clamping method, downward pressure stability, and jaw withdrawal method. The existing jaw structure mostly adopts an opening and closing clamping method. The clamping center is greatly affected by the assembly and motion accuracy, and the center position is unknown. It is difficult to find the working point to achieve uniform assembly force at both ends. In addition, it is easy to cause scratches or pull-out of the workpiece during withdrawal, resulting in bending, damage or pull-out of the lower elastic pin, and failure of the electrical connection.

[0007] In particular, a protrusion for hooking materials is provided at the bottom end of the elastic clamping piece, the clamping boss is provided above the protrusion, a clamping groove is formed between the protrusion and the clamping boss, and an opening and closing gap for completing the opening and closing clamping action is provided in the middle part of the elastic clamping piece along the vertical direction, which is in a loose exploded state when there is no package.

[0008] The wrapping movement mechanism is responsible for controlling the opening / closing state of the elastic clamping member, and the wrapping movement mechanism includes a nut, a second connecting plate, a second guide rail, a wrapping positioning slider and a wrapping positioning member, the clamping fixed seat is arranged below the second connecting plate, the wrapping positioning member is fixedly arranged on both sides of the second connecting plate, the elastic clamping member is wrapped and arranged in the wrapping positioning member, and the wrapping positioning member is provided with a positioning protrusion matching the clamping boss on the elastic clamping member; the nut is arranged through the middle part of the second connecting plate, and the lead screw passes through the clamping fixed seat, the nut and the first connecting plate from bottom to top in sequence, the nut cooperates with the lead screw in the hooking movement mechanism, and can drive the second connecting plate and the wrapping positioning member connected thereto to move, and the second guide rail is fixedly arranged on both sides of the wrapping positioning member.

[0009] Particularly, the first connecting plate in the hooking movement mechanism and the wrapping positioning piece of the wrapping movement mechanism are both milled with locking grooves, into which steel balls can be inserted to achieve locking with the locking positioning mechanism.

[0010] The locking and positioning mechanism is used to realize the positioning and locking of the wrapping movement mechanism and the wrapping movement mechanism, and the locking and positioning mechanism includes a locking boss, a locking gas joint, a locking groove, a steel ball, a first guide rail and a frame. The frame is hollow inside, and the locking boss is arranged on the inner wall of the frame, and the locking groove is arranged on the side wall of the first connecting plate and the wrapping positioning member, the locking gas joint is connected to the locking boss, and the locking boss is provided with a stepped hole, and the steel ball is arranged in the stepped hole, and the steel ball includes a clamping part and a movable part, the clamping part of the steel ball is clamped with the locking boss, and the movable part of the steel ball is movably connected with the locking groove, and the four inner side walls of the frame are symmetrically installed with the first guide rail and the wrapping movement slider, the first guide rail is slidably connected with the hooking movement slider, and the wrapping movement slider is slidably connected with the second guide rail in the wrapping movement mechanism, so as to realize the positioning of the hooking movement mechanism and the wrapping movement mechanism.

[0011] A clamping method for clamping materials using the above-mentioned single-drive dual-control assembly clamping device based on an elastic body comprises the following steps:

[0012] S1: Preparation

[0013] The clamping device is driven to move to the top of the material, the wrapping positioning piece is positioned, and compressed air is introduced into the locking air joint located at the wrapping positioning piece to drive the steel ball to engage with the wrapping positioning piece. At this time, the wrapping positioning piece is locked with the locking positioning mechanism, and the hooking movement mechanism is in an active state;

[0014] S2: Hook-in phase

[0015] The power source rotates forward. Since the wrapping positioning piece is in a locked state, the nut on the upper end of the wrapping positioning piece is stationary. The power source drives the screw rod to rotate forward, thereby driving the clamping claw assembly to move downward. When the bottom of the elastic clamping piece is separated from the wrapping positioning piece, the elastic clamping piece is in an exploded state. At this time, the clamping device is controlled to hook the material downward.

[0016] S3: Retraction phase

[0017] When the clamping device hooks into the material, the power source drives the screw to rotate in the opposite direction, driving the elastic clamping member to move upward, and the protrusion in the elastic clamping member hooks the material into the clamping groove, and the elastic clamping member continues to move upward. When the clamping boss interacts with the positioning protrusion in the wrapping positioning member, the elastic clamping member is converted into a closed state, and the material is retracted into the clamping device;

[0018] S4: Pressing stage

[0019] The clamping device moves to the position to be assembled, and after the positioning is completed by the wrapping positioning piece in the wrapping movement mechanism, the power source drives the screw to rotate forward, thereby driving the elastic clamping piece to move downward, and the material is squeezed downward through the bottom of the positioning protrusion to achieve press-fitting;

[0020] S5: Release phase

[0021] After the pressing action is completed, the compressed air at the wrapping positioning piece is released, and compressed air is introduced into the locking air joint at the first connecting plate to realize the locking of the hooking movement mechanism and the locking positioning mechanism, and the power source is controlled to drive the screw rod to rotate in the opposite direction, driving the wrapping positioning piece to move upward until it is separated from the elastic clamping piece. At this time, the elastic clamping piece is transformed into an exploded state, and the elastic clamping piece is separated from the material, completing the material release.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. Positioning, hooking, retraction, pressing and releasing are achieved through the relative movement of the tight positioning piece and the elastic clamping piece that can be exploded. The tight positioning piece does not need to move during assembly. After reaching the predetermined position (the shape of the tight positioning piece can be used for positioning when the precision requirement is high), the cable terminal can be pressed in and released only by the rotation of the screw rod. The clamping center is clear and the clamping and releasing process is more reliable, which reduces the damage rate and pull-out rate of the cable terminal when it is pressed in.

[0024] 2. The vertical movement of the hooking motion mechanism and the wrapping motion mechanism along the locking and positioning mechanism is controlled by one power source. The moving part and the stationary part are determined by the locking relationship between the steel ball and the locking groove, which reduces the number of power sources, greatly saves space occupation, and reduces the development cost;

[0025] 3. The hooking motion mechanism and the wrapping motion mechanism are integrated in a small space, and the hooking motion mechanism and the wrapping motion mechanism are accurately positioned through the four inner walls of the outer frame, so that the motion relationship is stable and the space is more compact.

[0062] S2: Hook-in phase

[0063] like Fig.10 As shown, the power source 4 rotates forward, and since the wrapping positioning member 21 is in a locked state, the nut 23 at the upper end of the wrapping positioning member 21 is stationary, and the power source 4 drives the screw rod 13 to rotate forward, thereby driving the clamping jaw assembly 12 to move downward.

[0068] S5: Release phase

[0069] like Fig.12 As shown, after the pressing action is completed, the compressed air at the wrapping positioning member 21 is released, and compressed air is introduced into the locking air joint 43 at the first connecting plate 14 to realize the locking of the hooking movement mechanism 1 and the locking positioning mechanism 3, and the power source 4 is controlled to drive the screw rod 13 to rotate in the opposite direction, driving the wrapping positioning member 21 to move upward until it is separated from the elastic clamping member 122.

A clamping method for material clamping using the single-drive dual-control assembly clamping device based on elastic body as claimed in claim 8, characterized in that: The following steps are involved: S1: Preparation The clamping device is driven to move to the top of the material, the wrapping positioning piece is positioned, and compressed air is introduced into the locking air joint located at the wrapping positioning piece to drive the steel ball to engage with the wrapping positioning piece. At this time, the wrapping positioning piece is locked with the locking positioning mechanism, and the hooking movement mechanism is in an active state; S2: Hook-in phase The power source rotates forward. Since the wrapping positioning piece is in a locked state, the nut on the upper end of the wrapping positioning piece is stationary. The power source drives the screw rod to rotate forward, thereby driving the clamping claw assembly to move downward. When the bottom of the elastic clamping piece is separated from the wrapping positioning piece, the elastic clamping piece is in an exploded state. At this time, the clamping device is controlled to hook the material downward. S3: Retraction phase When the clamping device hooks into the material, the power source drives the screw to rotate in the opposite direction, driving the elastic clamping member to move upward, and the protrusion in the elastic clamping member hooks the material into the clamping groove, and the elastic clamping member continues to move upward. When the clamping boss interacts with the positioning protrusion in the wrapping positioning member, the elastic clamping member is converted into a closed state, and the material is retracted into the clamping device; S4: Pressing stage The clamping device moves to the position to be assembled, and after the positioning is completed by the wrapping positioning piece in the wrapping movement mechanism, the power source drives the screw to rotate in the positive direction, thereby driving the elastic clamping piece to move downward, and the material is squeezed downward through the bottom of the positioning protrusion to achieve press-fitting; S5: Release phase After the pressing action is completed, the compressed air at the wrapping positioning piece is released, and compressed air is introduced into the locking air joint at the first connecting plate to realize the locking of the hooking movement mechanism and the locking positioning mechanism, and the power source is controlled to drive the screw rod to rotate in the opposite direction, driving the wrapping positioning piece to move upward until it is separated from the elastic clamping piece. At this time, the elastic clamping piece is transformed into an exploded state, and the elastic clamping piece is separated from the material, completing the material release.
