They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present invention.

[0036] In a specific embodiment of the present invention, Figures 1 to 10 As shown, it includes a base plate 1, a telescopic rod 2, a slider 3 and a locking block 4. Two strip plates 5 are symmetrically fixed on the base plate 1. The slider 3 is horizontally slidably connected and arranged between the two strip plates 5. The telescopic rod 2 is horizontally arranged at one end of the strip plate 5. The telescopic rod 2 is fixedly connected to the strip plate 5 or the base plate 1, and the telescopic end of the telescopic rod 2 is fixedly connected to one end of the slider 3.

[0037] The top surface of the slider 3 is provided with a receiving cavity 301 for clamping the lock iron 6;

[0038] The cross section of the locking block 4 matches the hollow portion 601 of the locking iron 6. Sockets 302 matching the hollow portion 601 are provided on both side walls of the slider 3. The locking block 4 slides in engagement with the two sockets 302. A strip-shaped through hole 501 is provided on any of the strip plates 5. The length of the strip-shaped through hole 501 is arranged along the sliding direction of the slider 3. The upper and lower side walls of the locking block 4 slide in engagement with the upper and lower side walls of the strip-shaped through hole 501, respectively.

[0039] A control component is provided on one side of the strip plate 5 , and the control component can control the locking block 4 to enter and exit the insertion hole 302 .

[0040] Specifically:

[0041] The four corners of the base plate 1 are fixed with support ears, which are provided with through holes, and the base plate 1 can be fixed to the working platform of the milling machine through the support ears;

[0042] The sliding block 3 is driven away from or close to the milling cutter of the milling machine by the telescopic end of the telescopic rod 2. When the locking iron 6 needs to be clamped, the sliding block 3 is away from the milling cutter of the milling machine, thereby facilitating the clamping of the locking iron 6 and preventing the milling cutter from causing harm to the workers.

[0043] The locking block 4 is controlled to enter and exit the insertion hole 302 by the control component, and the staff does not need to operate the locking block 4, thereby reducing the labor intensity of the staff in clamping the locking iron 6.

[0044] Place the portion of the locking iron 6 with the hollow portion 601 into the accommodating cavity 301, with the end of the locking iron 6 with the gate facing upward, and the bottom surface of the locking iron 6 in contact with the bottom wall of the accommodating cavity 301. The control component controls the locking block 4 to pass through the hollow portion 601. At this time, the locking block 4 is plugged into both sockets 302, and the locking iron 6 is fixed.

[0045] The telescopic rod 2 can be an electric telescopic rod, a hydraulic telescopic rod or a pneumatic telescopic rod, preferably an electric telescopic rod.

[0046] In some embodiments, two sliders 3 are provided, and the two sliders 3 are spaced apart from each other, and a connecting rod 7 is fixedly connected between the two sliders 3 .

[0047] Specifically, when the milling cutter degates the locking iron 6 on one slider 3, the degated locking iron 6 on another slider 3 can be removed, and then a locking iron 6 that needs to be degated can be put in, thereby achieving continuous operation and improving production efficiency.

[0048] In some embodiments, the length of the strip through hole 501 is greater than or equal to the sum of the lengths of the two sliders 3 plus the two connecting rods 7. The control component includes a fixing pin 8 and a control slide 9. One end of the locking block 4 protrudes from the strip through hole 501 and is fixedly connected to one end of the fixing pin 8. The fixing pin 8 is vertically arranged. The outer wall of the strip plate 5 with the strip through hole 501 is fixedly connected to the control plate 10. The control slide 9 is opened on the control plate 10. The end of the fixing pin 8 away from the locking block 4 slides with the control slide 9. The control slide 9 is an arc-shaped long hole, and both ends of the control slide 9 are away from the strip plate 5 with the strip through hole 501.

[0049] Specifically, when the slider 3 slides, the locking block 4 slides synchronously with the slider 3, and the fixing pin 8 slides synchronously with the locking block 4. As the fixing pin 8 slides within the control slide 9, the fixing pin 8 moves away from or closer to the strip plate 5, allowing the locking block 4 to be inserted into or slide out of the socket 302. When the fixing pin 8 is closest to the strip plate 5, the locking block 4 is plugged into both sockets 302. When the fixing pin 8 is located at the end of the control slide 9, one end of the locking block 4 is plugged into the socket 302 closest to the strip-shaped through-hole 501. The fixing pin 8 can be a cylindrical pin or a screw directly welded to the locking block 4. The top of the screw passes through the locking block 4 and is configured as an optical axis structure. Threads are provided between the optical axis structure and the screw cap, and are threadedly connected to the locking block 4.

[0050] In some embodiments, dovetail rails 303 are fixed on both sides of the slider 3 , dovetail rails 502 are provided on the opposite surfaces of the two strip plates 5 , and the dovetail rails 303 are slidably connected to the dovetail rails 502 .

[0051] Specifically, the sliding connection between the slider 3 and the strip plate 5 is achieved by the cooperation between the dovetail slide rail 303 and the dovetail slideway 502 .

[0052] In some embodiments, a first chamfer 304 is provided at one end of the insertion hole 302 away from the strip-shaped through hole 501 , and the first chamfer 304 is located at an end close to another insertion hole 302 .

[0053] Specifically, the first chamfer 304 is provided to facilitate the insertion of the locking block 4 .

[0054] In some embodiments, a second chamfer 401 is provided at one end of the locking block 4 close to the slider 3 .

[0055] Specifically, the second chamfer 401 is provided to facilitate the insertion of the locking block 4 into the insertion hole 302 away from the strip-shaped through hole 501 .

[0056] In some embodiments, a vertical plate 305 for receiving the rib 602 of the locking iron 6 is integrally formed on the top of the slider 3 .

[0057] Specifically, the staff places the part of the locking iron 6 with the hollow part 601 into the accommodating cavity 301, and the end of the locking iron 6 with the gate faces upward, and the bottom surface of the locking iron 6 contacts the bottom wall of the accommodating cavity 301, then the rib 602 is supported on the vertical plate 305, and the vertical plate 305 plays a stable supporting role when the milling cutter mills the gate, reducing the burden on the locking block 4 and extending the service life of the locking block 4.

[0058] In some embodiments, a chip discharge opening 306 is defined on the bottom wall of the accommodating cavity 301 .

[0059] There is a gap between the bottom surface of the slider 3 and the top surface of the base plate 1 .

[0060] Specifically, debris may enter the accommodating cavity 301 , and the debris may fall out of the accommodating cavity 301 through the chip discharge opening 306 and land on the bottom plate 1 . The staff can use tools to clean out the debris on the bottom plate 1 .

[0061] The working principle of the locking iron milling gate fixing fixture of the gondola lock of the present invention is as follows: when the slider 3 slides, the locking block 4 slides synchronously with the slider 3, and the fixing pin 8 slides synchronously with the locking block 4. The fixing pin 8 slides within the control slide 9, and the fixing pin 8 moves away from or closer to the strip plate 5, so that the locking block 4 can be inserted into or slide out of the insertion hole 302. When the fixing pin 8 is closest to the strip plate 5, the locking block 4 is plugged into both insertion holes 302. When the fixing pin 8 is at the end of the control slide 9, one end of the locking block 4 is plugged into the insertion hole 302 closest to the strip through hole 501.

[0062] The slide block 3 is moved away from or close to the milling cutter of the milling machine by the telescopic end of the telescopic rod 2. When the locking iron 6 needs to be clamped, the slide block 3 is away from the milling cutter of the milling machine, thereby facilitating the clamping of the locking iron 6 and preventing the milling cutter from causing harm to the staff.

[0063] When the milling cutter is de-gating the locking iron 6 on one slider 3, the de-gating locking iron 6 on the other slider 3 can be removed, and then a locking iron 6 that needs to be de-gated can be put in, thereby achieving continuous work and improving production efficiency.

[0064] In the initial state, a fixing pin 8 is located in the middle of the control slide 9, that is, the position where the fixing pin 8 is closest to the strip plate 5, and at this time the slider 3 is located below the milling cutter, and the other fixing pin 8 is located at one end of the control slide 9. The staff puts the part of the lock iron 6 with the hollow part 601 into the accommodating cavity 301 away from the milling cutter, and the end of the lock iron 6 with the gate faces upward, the bottom surface of the lock iron 6 contacts the bottom wall of the accommodating cavity 301, and the rib 602 is carried on the vertical plate 305. The telescopic end of the telescopic rod 2 drives the slider 3 to slide, and the locking block 4 slides synchronously with the slider 3, and the fixed The fixed pin 8 slides synchronously with the locking block 4, and the fixed pin 8 slides in the control slide 9. The fixed pin 8 away from the milling cutter will gradually approach the strip plate 5 until it stops at the middle of the control slide 9. The locking block 4 can pass through the hollow part 601 and be plugged into both sockets 302. At this time, the gate of the lock iron 6 can be milled. At the same time, the other fixed pin 8 will gradually move away from the strip plate 5, and finally one end of the lock block 4 will be plugged into the socket 302 near the strip through hole 501. At this time, the other lock iron 6 that needs to be de-gated can be placed in the accommodating cavity 301.

[0065] The various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. Similar parts between the various embodiments can be referred to in conjunction with each other, and the various embodiments can be combined with each other. For the devices disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple.
