[0025] As Figures 2-5 , the locking end head 19 is fixed with a spring connecting disc 18 and a connecting cylinder 16, the spring connecting disc 18 is fixed with a plurality of sliding rods 17, the sliding rods 17 can slide in the sliding groove on the housing in the vertical direction, a tension spring 20 is arranged between the housing and the spring connecting disc 18, the tension spring 20 is sleeved on the sliding rods 17, the connecting cylinder 16 is fixed with a guide rail reversing sliding block 15, the reversing sliding block 15 is clamped in the guide rail A 14 and can slide along the guide rail A 14, the guide rail A 14 is fixed on the transmission block 11, the side surface of the transmission block 11 is fixed with a guide rail side sliding block 13, the guide rail side sliding block 13 is clamped in the track B 12 and can slide along the track B 12, the track B 12 is fixed on the housing, the guide rail A 14 is arranged obliquely, and the track B 12 is arranged horizontally.

[0026] As Figures 2-5 , the transmission block 11 is connected with an electric module and / or a manual module, under the control of the electric module or the manual module, the locking end head 19 can be switched between the retracted state and the unlocked state.

[0027] As Figures 2-3 , the electric module includes an electric cylinder 6, the cylinder end of the electric cylinder 6 is fixed on the shell, the moving end of the electric cylinder 6 is fixed on the push block 7, the push block 7 is fixed on the rubber pad 8, and the contact between the side surface of the transmission block 11 and the rubber pad 8 is surface contact.

[0028] As Figures 2-3 , the manual module includes a threaded rod 9 of an electric cylinder, the threaded rod 9 is screwed between two groups of supports, the two groups of supports are fixed on the shell, one end of the threaded rod 9 extends from the shell to the outside and is fixedly connected with the hand wheel 10, and the other end of the threaded rod 9 is fixedly connected with the control plate, and the contact between the side surface of the transmission block 11 and the control plate is surface contact.

[0029] In order to facilitate cooperation, the side surface of the transmission block 11 is fixed with a side vertical plate, and the side vertical plate cooperates with the rubber pad 8 and the control plate.

[0030] In order to prevent the threaded rod 9 from interfering with the side vertical plate, a groove for the threaded rod 9 to pass through is arranged on the side vertical plate.

[0031] As Figures 2-5 , the spring connecting disc 18 is fixed with the sliding rod 17 through screws, and the four tension springs 20 are uniformly distributed on a space columnar surface.

[0032] As Figure 1 , the shell includes an outer shell 5, the outer shell 5 is provided with a side cover A3 and a side cover B4, the outer shell 5 is fixed on the end surface of the rotary table 1 through screws, and the side cover A3 and the side cover B4 can be screwed on the outer shell 5, so that the packaging of the novel launching rotary table locking device is realized.

[0033] The push block 7 is screwed and fixed with the push rod of the electric cylinder 6. The rubber pad 8 is bonded to the push block 7.

[0034] The specific working process of the launching rotary table locking device is as follows:

[0035] Electric mode:

[0036] S10, enter the contraction state

[0037] As Figure 2 , 6The launch turntable locking device is in the initial state (unlocked state). The electric cylinder 6 is activated, causing its moving end to extend. This extends the transmission block 11 to the right via the push block 7 and rubber pad 8. Because the transmission block 11 is constrained by the track B12, its operation is stable. Due to the pressure from the inclined surface of the transmission block 11, the reversing slider 15 begins to move downwards. Because the reversing slider 15 is constrained by the guide rail A14, its operation is stable. The reversing slider 15 pushes the connecting cylinder 16, locking end 19, spring connecting plate 18, and moving rod 17 to move downwards simultaneously (at the same time, the tension spring 20 is stretched). The locking end 19 gradually extends into the base 2, entering a retracted state. Figure 7 .

[0038] S20, Enter unlocked state

[0039] like Figure 2 , 7 With the launch turntable locking device unlocked, the electric cylinder 6 is activated, causing its moving end to retract. The transmission block 11 loses its left-side constraint, and the reversing slider 15 is in an unstable state. Under the tension of the tension spring 20, the connecting cylinder 16, locking end 19, spring connecting plate 18, moving rod 17, and reversing slider 15 all move upwards synchronously (at this time, the reversing slider 15 pushes the transmission block 11 to the left). The locking end 19 gradually pulls out from the base 2, returning to the unlocked state. Figure 6 .

[0040] Manual mode:

[0041] S10, Entering the contraction state

[0042] like Figure 2 , 8 The launch turntable locking device is in the initial state (unlocked state). Turning the handwheel 10 moves the threaded rod 9 to the right, which in turn pushes the transmission block 11 to the right via the control panel. Because the transmission block 11 is constrained by the track B12, its operation is stable. Due to the pressure from the inclined surface of the transmission block 11, the reversing slider 15 begins to move downwards. Because the reversing slider 15 is constrained by the guide rail A14, its operation is stable. The reversing slider 15 pushes the connecting cylinder 16, locking end 19, spring connecting plate 18, and moving rod 17 to move downwards simultaneously (at the same time, the tension spring 20 is stretched). The locking end 19 gradually extends into the base 2, entering a retracted state. Figure 9 .

[0043] S20, Enter unlocked state

[0044] like Figure 2 , 9, the transmission block 11 loses the left constraint, the reversing slider 15 is in an unstable state, under the action of the pulling force of the pull spring 20, the connecting cylinder 16, the locking end head 19, the spring connecting disc 18, the movable rod 17 and the reversing slider 15 are synchronously moved upward (at this time, the reversing slider 15 pushes the transmission block 11 to move leftward), the locking end head 19 gradually locks the end head 19 out of the base 2, and the locking state is as shown in FIG. 2. Figure 8 .

[0045] The characteristics of the patent are as follows:

[0046] S1, the device realizes the electric and manual integrated locking function of the launching turntable, so that the launching turntable locking has high reliability, and the change of the locking direction solves the problem of limited space arrangement in the height direction of the launching turntable.

[0047] S2, the manual module and the electric module of the novel launching turntable locking device are independent of each other, so as to ensure the high reliability of the locking device.

[0048] S3, the reversing design of the transmission locking part and the portable box packaging solve the problem of limited internal space arrangement in the height direction of the launching turntable, and are convenient for maintenance.

[0049] S4, the mounting surfaces of the shell part in different directions better meet the design requirements of locking in different directions.
