Specific embodiments

[0031] In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present utility model, some well-known technical features in the art are not described.

[0032] The present application discloses a locking device for a dual-axis turntable. By cooperating with an anti-slip wheel, a clamping mechanism and an anti-slip clamp block outside the vertical plate, and making the clamping mechanism and the anti-slip clamp block detachably cooperate, the problem of high replacement cost of the existing locking device with an integrated structure is solved.

[0033] The first embodiment is as Figure 1 shown. The locking device for the dual-axis turntable includes: a base 1, a vertical plate 2, a turntable body 3, an anti-slip wheel 4, a clamping mechanism and an anti-slip clamp block 12.

[0035] The clamping mechanism is installed on the vertical plate 2. Two anti-slip clamping blocks 12 are detachably installed on the clamping mechanism. The anti-slip wheels 4 are arranged between the two anti-slip clamping blocks 12.

[0036] The clamping mechanism is used to drive the anti-slip clamping blocks 12 to cooperate with the anti-slip wheels 4 to lock and fix the turntable body 3.

[0037] One end of the turntable body 3 is connected to the first motor. A second motor is provided on the part of the turntable body 3 located between the two vertical plates 2. The first motor drives the turntable body 3 and the second motor to rotate, and the second motor drives the parts on the turntable body 3 to rotate to achieve dual-axis rotation.

[0038] Regarding the clamping mechanism, as Figure 1 and 5 shown, the clamping mechanism includes: a housing 5, a T-shaped block 7, a lead screw 10, a motor 11, a connecting rod 8, and a locking plate 9.

[0039] The housing 5 is installed on the vertical plate 2. The housing 5 is provided with a T-shaped groove 6. The T-shaped block 7 and the lead screw 10 are arranged in the T-shaped groove 6. The two T-shaped blocks 7 are connected to the lead screw 10. The motor 11 is connected to the lead screw 10. The two connecting rods 8 are respectively connected to the two T-shaped blocks 7. The two locking plates 9 are respectively connected to the two connecting rods 8. Among them, the base of the motor 11 is connected to the housing 5 or the vertical plate 2, and its power shaft is connected to the lead screw 10.

[0040] The two anti-slip clamping blocks 12 are respectively detachably installed on the two locking plates 9.

[0041] In this embodiment, two lead screws can be arranged in the two T-shaped grooves 6 as Figure 1 shown, and the two lead screws are respectively connected to the two T-shaped blocks 7 and the two motors 11. Or a bidirectional lead screw can be arranged in the T-shaped groove 6, and the two T-shaped blocks 7 are connected to the bidirectional lead screw.

[0042] As Figure 2 and 5 shown, the end of the anti-slip clamping block 12 is provided with an insertion rod 13, and the locking plate 9 is provided with an insertion hole 14. The insertion rod 13 of the anti-slip clamping block 12 is inserted into the insertion hole 14 of the locking plate 9.

[0043] In this embodiment, the locking device further includes: a positioning pin 17.

[0044] The side wall of the connecting rod 8 is provided with two fixing blocks 15. The insertion rod 13 of the anti-slip clamping block 12 passes through the insertion hole 14 and is arranged between the two fixing blocks 15.

[0045] Positioning holes 16 are formed in the fixing blocks 15 and the insertion rod 13. The positioning pin 17 is inserted into the positioning holes 16 of the fixing blocks 15 and the insertion rod 13.

[0046] The fixing strength of the anti-slip clamping block 12 is improved by the positioning pin 17, and the anti-slip clamping block 12 can be further prevented from rotating.

[0047] In this embodiment, the cross-sections of the insertion rod 13 and the insertion hole 14 are rectangular.

[0048] It is convenient to position the insertion rod 13 and prevent the anti-slip clamping block 12 from rotating.

[0049] In this embodiment, the locking plate 9 is arc-shaped.

[0050] As Figure 5 shown, the anti-slip clamping block 12 is an arc-shaped plate, which is convenient for installing the anti-slip clamping block 12.

[0051] As Figure 2 shown, anti-slip protrusions 18 are provided on the opposite sides of the two anti-slip clamping blocks 12.

[0052] The friction between the anti-slip clamping block 12 and the anti-slip wheel 4 is increased, and the locking and fixing effect of the anti-slip clamping block 12 and the anti-slip wheel 4 is improved.

[0053] As Figure 1 and 3 shown, external connection holes 23 are provided at the four corners of the base 1.

[0054] It is convenient to connect the base 1 and external equipment through the external connection holes 23.

[0055] Working method: When the rotating table main body 3 stops rotating, the user can control the motor 11 to drive the lead screw 10 to drive the T-shaped block 7 and the locking plate 9 to move, so that the anti-slip clamping block 12 clamps and fixes the anti-slip wheel 4, and then locks the rotating table main body 3 to prevent it from rotating.

[0056] When the anti-slip clamping block 12 needs to be disassembled, the positioning pin 17 can be first pulled out from the positioning hole 16, and then the insertion rod 13 of the old anti-slip clamping block 12 can be taken out from the insertion hole 14, and then the insertion rod 13 of the new anti-slip clamping block 12 can be inserted into the insertion hole 14 to disassemble and replace the anti-slip clamping block 12.

[0057] Second embodiment, on the basis of the first embodiment, a brake disc 19 and a brake block 21 are added to further lock and fix the rotating table main body 3 to make it more stable.

[0058] As Figure 3 shown, the locking device further includes: a brake disc 19, an electric push rod 20 and a brake block 21.

[0059] The brake disc 19 is installed on the rotating table main body 3, the electric push rod 20 is installed on the vertical plate 2, and the brake block 21 is installed on the electric push rod 20.

[0061] As Figure 3 shown, the brake disc 19 and the anti-slip wheel 4 are respectively arranged at both ends of the turntable body 3. The brake disc 19 can be arranged at the position between the turntable body 3 and the vertical plate 2 as Figure 3 shown, or can be arranged at the position of the vertical plate 2 far from the turntable body 3.

[0062] Through the cooperation of the brake block 21 and the brake disc 19, combined with the cooperation of the anti-slip clamp block 12 and the anti-slip wheel 4, the turntable body 3 can have two fixing methods. The combination of the two fixing methods is used to further lock and fix the turntable body 3, making it more stable, and further solving the problem that the locking and fixing method in the prior art is single and the locking effect is not very good.

[0063] As Figure 4 shown, anti-slip lines 22 are provided on both the brake block 21 and the brake disc 19.

[0064] The friction between the brake block 21 and the brake disc 19 is increased, and the locking and fixing effect of the brake block 21 and the brake disc 19 is improved.

[0065] Working method: On the basis of the first embodiment, when the turntable body 3 stops rotating, while the user controls the motor 11, the lead screw 10, the anti-slip clamp block 12 and the anti-slip wheel 4 to cooperate to fix the turntable body 3, the user can control the electric push rod 20 to drive the brake block 21 to move with its output end, so as to make it contact with the anti-slip lines 22 on the brake disc 19, and further lock and fix the turntable body 3, making the turntable body 3 more stable.

[0066] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as a limitation of the present invention itself. Various changes can be made to it in form and detail without departing from the spirit and scope of the present invention defined by the appended claims.
