The existing equipment has difficulties in assembling this structure, low processing efficiency, is not conducive to improving economic benefits, and at the same time, the equipment is prone to instability during operation, affecting the reliability of the structure. Summary of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a processing device for assembling and connecting articulated workpieces, which has a simple structure, reasonable layout, high automation degree, effectively realizes the combined processing of the base and the side plate, and has good use effects.

[0004] To achieve the above object, the utility model provides a processing device for assembling and connecting articulated workpieces, including a frame. A first feeding track for feeding the workpiece base and a second feeding track for feeding the workpiece side plate are arranged on the frame. A processing track is arranged on the frame. A pushing mechanism for feeding the base into the processing track is arranged between the processing track and the first feeding track. A driving mechanism for driving the base to slide on the processing track is arranged on one side of the processing track. The driving mechanism includes a driving seat and a power source for driving the driving seat to slide along the processing track. A plurality of positioning plates are arranged on the driving seat. The positioning plates extend towards each workpiece base on the processing track with abutting heads. A positioning groove for cooperating with the edge of the workpiece base is arranged on the abutting head. A flaring mechanism for opening the connecting wings on both sides of the workpiece base, a positioning mechanism for clamping the connecting wings to pre-assemble the articulation holes and the plug feet, and a clamping mechanism for tightening the connecting wings are sequentially arranged on the frame corresponding to the position of the processing track. The second feeding track is arranged corresponding to the positioning mechanism. A feeding mechanism for clamping and feeding the side plate is arranged between the second feeding track and the processing track.

[0005] The beneficial effects of such a setting are as follows: With such a setting, the first feeding track is used to feed the workpiece base, and the second track is used to feed the workpiece side plates. The feeding of the materials here preferably uses a vibrating bowl, which belongs to the prior art and will not be elaborated here. The base enters the processing track through a pushing mechanism, which can be a push rod or a manipulator, as long as it can send the materials into the processing track. After the materials are squeezed into the processing track, they can cooperate with the contact head of the positioning plate. The positioning groove on the contact head can cooperate with the side wall of the base to achieve the positioning of the base. At the same time, due to the movement of the driving seat, the base can reach each processing station. The connecting wings can be opened by the flaring mechanism, which is convenient for subsequent cooperation with the side plates. After flaring, the base is sent to the positioning mechanism. At this time, the side plates also reach the corresponding positions under the action of the feeding mechanism, which can be a manipulator or a clamping jaw. After aligning the pins on the side plates with the connecting ports, the connecting wings can be closed by the positioning mechanism, so that the pins can be inserted into the connecting ports. The positioning mechanism can be set as a clamping jaw or can adopt structural forms such as a push block to achieve the closing driving action. The pre-positioning can be realized through the positioning mechanism, which is convenient for subsequent tight-fitting actions. After the pre-positioning is completed, it is further fed to the clamping mechanism to bend the connecting wings to a predetermined angle to complete the combination of the workpiece. This structure is simple, has a high degree of automation, low labor costs, and reliable connections, and has good use effects.

[0006] As a further setting of the present invention, the flaring mechanism includes a flaring seat, a lifting motor, and a mass block. The flaring seat is arranged on one side of the processing track, the lifting motor is installed on the flaring seat, the mass block is connected to the output end of the lifting motor, the end of the mass block is arc-shaped, and a guiding groove is also arranged on the flaring seat. The mass block is slidably matched with the guiding groove.

[0007] The beneficial effects of such a setting are as follows: With such a setting, the mass block is controlled to fall by the lifting motor, so as to realize the flaring action by squeezing the workpiece base, making the connecting wings open, which is convenient for subsequent installation of the side plates. This structure is simple and easy to realize, and has good use effects.

[0008] As a further setting of the present invention, the pushing mechanism includes a push rod and a push motor for driving the push rod to expand and contract. One end of the push rod is connected to the output end of the push motor, and the other end is arranged corresponding to the end of the first feeding track. A guiding track is arranged on the machine frame corresponding to the movement direction of the push rod. The guiding track is communicated with the first feeding track, and a positioning pin and a guiding motor for controlling the positioning pin to approach or move away from the guiding track are arranged on the guiding track corresponding to the position of the first feeding track.

[0009] The beneficial effect of such arrangement is as follows: with such arrangement, the workpiece base is fed into the workpiece through the first feed track, and when it moves to the intersection of the first feed track and the guide track, positioning can be achieved through the locating pin to ensure accurate positioning, and after positioning is completed, the locating pin is withdrawn through the guide motor, and the workpiece base is pushed into the processing track by the ejector rod, thereby completing the feeding of the material. This structure is simple, easy to implement, and has a good use effect.

[0010] As a further configuration of the present invention, the positioning mechanism includes a positioning cylinder, a positioning seat and two positioning clamping arms. The positioning cylinder is arranged at the bottom of the processing track, the positioning seat is connected to the output end of the positioning cylinder, and the end of the positioning seat close to the processing track is provided with two inclined surfaces for resisting the retraction of the corresponding positioning clamping arms. The positioning clamping arm is hingedly arranged on the bracket, one end of the positioning clamping arm is exposed on the processing track, and the other end resists against the inclined surface of the positioning seat.

[0011] The beneficial effect of such an arrangement is that, through the lifting and sliding movement of the positioning seat, the inclined surface on the positioning seat interacts with the positioning clamp arm. Since the positioning clamp arm is hinged to the bracket, the end of the positioning clamp arm close to the inclined surface expands outward, and then the other end of the positioning clamp arm closes, thereby realizing the pre-clamping positioning action. Further, through the moving away of the positioning seat, the positioning clamp arm moves in the opposite direction, thereby completing the opening of the positioning clamp arm. This structure is simple, effectively realizes the predetermined effect, and has a good use effect.

[0012] As a further configuration of the utility model, one end of the positioning clamp arm exposed on the processing track is provided with a slot for cooperating with the pin.

[0013] The beneficial effect of such a setting is that such a setting can better drive the connecting wings to close, avoid squeezing the pins out of the connecting port, avoid interference from the pins, ensure the deformation effect of the connecting wings, improve the reliability of the structure, and at the same time, the structure is simple, easy to implement, and has a good use effect.

[0014] As a further configuration of the utility model, the clamping mechanism includes a clamping cylinder and a clamping block, the clamping block includes a resisting portion that resists on the workpiece base and guide portions arranged on both sides of the resisting portion, a guide groove is arranged between the resisting portion and the guide portion, and the side wall of the guide groove that contacts the connecting wing is arranged in an inclined surface.

[0015] The beneficial effect of such a setting is that, by means of the cooperation between the guide groove and the connecting wing, when the clamping block moves toward the workpiece base, the connecting wing moves against the inclined side wall of the guide groove, thereby driving the folding action of the connecting wing through the side wall. This method is simple, can effectively fasten the connecting port and the pin on the connecting wing, and has a good use effect.

[0016] As a further setting of the present utility model, a clearance groove for inserting the pin is provided on the side wall of the guiding groove in contact with the connecting wing.

[0017] The beneficial effect of such a setting is as follows: With such a setting, it ensures that the structure smoothly makes the connecting wing fold and clamp, avoids interference caused by the pin, ensures the stability of the structure, ensures the processing effect, and has a good use effect.

[0018] As a further setting of the present utility model, a bracket is provided at the bottom of the processing track corresponding to the position of the clamping mechanism, and a supporting block for supporting the workpiece base extends from the bracket to the bottom surface of the processing track.

[0019] The beneficial effect of such a setting is as follows: With such a setting, it can achieve the abutting positioning of the base, ensure that the connecting wings on both sides of the base can stably receive force and fold inward, further improve the reliability of the structure, ensure the smooth operation of the structure, and at the same time, the structure is simple, easy to implement, and has a good service life.
