[0028] The present application will be further described below in conjunction with the drawings and specific embodiments.

[0029] In combination Figures 1-6 The embodiment discloses a marking tool rotating mechanism, aiming at solving the problem of manual adjustment of direction or material turning during marking of a relay shell, and realizes turning and positioning of the relay shell through an automatic mechanism, thereby improving marking efficiency and accuracy.

[0030] The marking tool rotating mechanism comprises a turning support 100, which is a support structure of the whole mechanism and is used for mounting and fixing other components. Figure 2 As shown in the figure, the turning support 100 is an L-shaped structure, and a support frame 101 is connected to the top vertical section of the turning support 100. The support frame 101 is a vertical plate structure and is used for mounting components such as a push-pull cylinder 106, a rack 103, a guide block 102 and a bearing seat 108 of a gear 107. A protective plate 1011 is arranged on the outer side of the support frame 101, and the protective plate 1011 is a cover plate structure with an n-shaped cross-sectional profile, which is used for shielding and protecting the working components on the support frame 101 and providing a stable and clean working environment for the working components.

[0031] In combination Figure 3 As shown in the figure, the push-pull cylinder 106 is vertically arranged on the side wall of the support frame 101, and the telescopic end of the push-pull cylinder 106 is vertically arranged and connected with the rack 103. The bottom of the rack 103 is provided with a connecting plate 105 connected with the telescopic end of the push-pull cylinder 106, and the guide block 102 is arranged between the turning support 100 and the rack 103 to control the stable up-down movement of the rack 103. It should be noted that the guide block 102 is connected with the support frame 101 in a detachable manner, which is beneficial to finely adjust the installation position of the guide block 102 according to the actual situation, so as to ensure that the rack 103 moves more stably. Two left and right distributed pressing plates 104 are further arranged on the guide block 102, which are used for preventing the rack 103 from falling off or mispositioning from the guide block 102, which is beneficial to further stabilize the movement of the rack 103.

[0032] Further, the push-pull cylinder 106 is connected to the bottom of the support frame 101, the rack 103 is located above the push-pull cylinder 106 and can slide up and down, and the push-pull limiting rod 109 is arranged at the end of the stroke path of the rack 103 on the top of the support frame 101, which is used for limiting the up-position of the rack 103 to prevent excessive movement. In the embodiment, the push-pull limiting rod 109 specifically adopts a bolt, and the stroke limit of the rack 103 is controlled by adjusting the installation position of the bolt, thereby realizing the stable rotating stroke of the rotating block 200.

[0033] The rack 103 is meshed with a gear 107, and the rotation axis of the gear 107 is connected to the side wall of the support frame 101 via a bearing seat 108. When the rack 103 moves up and down, it can drive the gear 107 to rotate.

[0035] The fixture base 500 is provided with a fixture slot for placing the relay 600 to be marked. In this embodiment, the fixture base 500 is provided with two fixture slots arranged side by side. The bottom of the fixture slot is provided with a hollow structure to facilitate back marking operation. On the rotating block 200, the hollow structure is manifested as a marking through hole 203. This allows the rotating block 200 to rotate the relay 600 to be marked by 180 degrees, and the external marking machine located directly above can still perform unobstructed marking operation on the back of the relay.

[0036] The rotating block 200 is located above the tooling slot and is equipped with a pressing and positioning component 300. The pressing and positioning component 300 has a pressing claw 304 capable of pressing down to hold the relay 600 to be marked, ensuring its stability and accuracy during the marking process. Specifically, as shown... Figure 5 As shown, the pressing positioning assembly 300 includes a first support 301 connected to the rotating block 200. A pressing cylinder 302 is provided on the first support 301. A lifting plate 303 is connected to the movable end of the pressing cylinder 302. A pressing claw 304 adapted to the position of the tooling slot is provided on the lifting plate 303. The bottom of the pressing claw 304 is provided with a positioning groove 3041 corresponding to the top contour of the tooling seat 500. The inner end of the pressing claw 304 is provided with a pressing flange 3042 adapted to the top position of the relay 600 to be marked.

[0037] The bottom of the clamping claw 304 is provided with a positioning groove 3041, and the top of the tooling base 500 is provided with a positioning flange 501 that matches the positioning groove 3041. The two can form a stable stroke limiting structure.

[0038] Further, the lifting plate 303 is provided with a positioning reference block 305, which can abut against the top of the first limiting block 201 when the lifting plate 303 is lowered, so as to ensure the accurate and reliable lowering distance of the pressing claw 304, and avoid excessive extrusion of the relay.

[0039] The rotary block 200 is provided with a front and rear positioning assembly 400 on the front and rear side facing the tool groove, and the front and rear positioning assembly 400 has a springing positioning column 405 capable of transversely moving to position the relay to be marked 600. Figure 6 As shown, the front and rear positioning assembly 400 comprises a second support 401 connected to the rotary block 200, and the second support 401 is provided with a transverse moving cylinder 402, the movable end of the transverse moving cylinder 402 is connected with a transverse moving plate 403, the transverse moving plate 403 is connected with an extension block 404, and the springing positioning column 405 is arranged on the extension block 404 in a horizontal posture, and the transverse moving cylinder 402 can drive the positioning end of the springing positioning column 405 to move close to and abut against the side wall of the relay to be marked 600, so as to ensure the front and rear position accuracy of the relay to be marked 600 in the marking process.

[0040] In the specific implementation process, the relay to be marked 600 is placed into the tool groove of the tool seat 500 by using an external transfer manipulator, the pressing claw 304 in the downward pressing positioning assembly 300 is lowered to longitudinally clamp and constrain the relay to be marked 600, at the same time, the springing positioning column 405 of the front and rear positioning assembly 400 moves forward to abut against one side of the relay to be marked 600, so as to form front and rear positioning constraint, and the top shell surface of the relay to be marked 600 can be stably marked by the external marking machine in this state, then the rotary block 200 drives the relay to rotate by 180 degrees, so that the back shell of the relay to be marked 600 faces upward, and the marking machine can mark the back shell of the relay again.

[0041] The above embodiments are only used to illustrate the technical solutions of the present application, but not limit the same; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
