Description

Technical Field

[0001] This utility model belongs to the technical field of tooling fixture components, specifically relating to an auxiliary anti-drop device and its tooling fixture. Background Technology

[0002] Tooling fixtures generally require auxiliary anti-drop devices to clamp the workpiece during processing. Most existing tooling fixtures do not have anti-drop devices installed or use imported anti-drop devices, which are expensive and have a long purchase cycle.

[0003] Therefore, there is an urgent market need for an inexpensive and easy-to-use auxiliary anti-fall device. Utility Model Content

[0004] To address the technical problem of existing tooling fixtures lacking anti-fall devices or using imported ones, this utility model discloses an auxiliary anti-fall device and its tooling fixture, including a base, a clamping block rotatably connected to the base at its center, one end of the clamping block being a clamping end, and the other end being a counterweight end. A limiting post is located below the base. Under the action of the counterweight end, the clamping block can rotate so that the side of the clamping end contacts the limiting post. When the clamping block is rotated until the side of the short end of the clamping block contacts the limiting post, the counterweight, under the action of gravity, keeps the long end of the entire clamping block in the anti-fall open state.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An auxiliary anti-drop device includes a base; The clamping block has an overall "L" shaped structure. The middle part of the clamping block is rotatably connected to the base. One end of the clamping block is the clamping end, and the other end of the clamping block is the counterweight end. A limiting post is disposed on one side of the base; The limiting post is located below the base, and the clamping block can rotate under the action of the counterweight end so that the side of the clamping end contacts the limiting post.

[0006] Furthermore, the clamping block is also equipped with a counterweight, which is located at the counterweight end of the clamping block.

[0007] Furthermore, the counterweight has a cylindrical structure.

[0008] Furthermore, the middle part of the clamping block is rotatably connected to the base via a locking screw.

[0009] In addition, this utility model also claims protection for a tooling fixture, including a base plate, wherein the base plate is equipped with any of the above-mentioned auxiliary anti-drop devices.

[0010] Compared with existing technologies, the beneficial effects of this solution are: This utility model provides an auxiliary anti-drop device and its tooling fixture, including a base, a clamping block rotatably connected to the base in the middle, one end of the clamping block being the clamping end and the other end being the counterweight end, and a limiting post located below the base. The clamping block can rotate under the action of the counterweight end, causing the side of the clamping end to contact the limiting post. The clamping block has an "L"-shaped plate structure, with its middle part rotatably connected to the base via a locking screw. The long end of the clamping block is the clamping end, and the counterweight end is the short end. The limiting post restricts the opening and closing positions of the clamping block, achieving effective anti-drop without affecting workpiece clamping. After manual loading, the counterweight can be moved to switch between open and closed states. When the long end of the clamping block is pressed against the workpiece, the angle between the long end and the horizontal line is approximately 25-40°. The short end of the clamping block is perpendicular to the long end, and the angle between the short end and the horizontal line is approximately 50-65°. Under the influence of gravity, the center of the entire clamping block shifts, thus creating a gravity-locked effect. Rotating the clamping block until the side of the short end contacts the limiting post, the counterweight, under gravity, keeps the long end of the clamping block in the anti-drop open state. This invention features simple and reliable mechanical action, highly interchangeable components, and a high cost-performance ratio. Attached Figure Description

[0012] The reference numerals in the attached figures are as follows: Base 1, clamping block 2, clamping end 21, counterweight end 22, counterweight block 23, limit post 3, locking screw 4. Detailed Implementation

[0013] The present invention will now be described in further detail with reference to the accompanying drawings.

[0014] This utility model claims protection for an auxiliary anti-drop device, such as... Figure 1 As shown, it includes base 1; The clamping block 2 has an overall "L" shaped structure. The middle part of the clamping block 2 is rotatably connected to the base 1. One end of the clamping block 2 is the clamping end 21, and the other end of the clamping block 2 is the counterweight end 22. A limiting post 3 is disposed on one side of the base 1; The limiting post 3 is located below the base 1, and the pressing block 2 can rotate under the action of the counterweight end 22 so that the side of the pressing end 21 contacts the limiting post 3.

[0015] According to a specific embodiment of this utility model, the base 1 adopts a columnar structure, and the upper end of the base 1 has a conical structure to facilitate the installation of the clamping block 2. Four connecting holes are opened along the circumference on the inclined surface. The base 1 is installed on the base plate of the tooling fixture through bolts installed in the four connecting holes. The clamping block 2 connecting hole is opened in the middle of the base 1. The limiting post 3 is fixedly connected to the base plate.

[0016] The clamping block 2 has an "L"-shaped plate structure. The middle part of the clamping block 2 is rotatably connected to the base 1 via a locking screw 4. The long end of the clamping block 2 is the clamping end 21, and the counterweight end 22 is the short end. The position of the limiting post 3 restricts the opening and closing position of the clamping block 2, achieving the effect of effectively preventing it from falling and not affecting the workpiece clamping. The counterweight 23 can offset the center of the entire clamping block 2, allowing the auxiliary anti-fall device to self-lock by gravity in the open and closed states. At the same time, the counterweight 23 can be equipped with a conspicuous color for easy identification by the operator.

[0017] After manual loading, the counterweight 23 can be toggled between open and closed states. Specifically, when the long end of the clamping block 2 is pressed against the workpiece, as... Figure 2 As shown, the angle between the long end and the horizontal line is approximately 25-40°, and the short end of the clamping block 2 is perpendicular to the long end of the clamping block 2. At this time, the angle between the short end of the clamping block 2 and the horizontal line is approximately 50-65°. In this way, the counterweight 23 can cause the center of the entire clamping block 2 to shift under the action of gravity, thereby giving the clamping block 2 a gravity self-locking effect. When the clamping block 2 is rotated until the side of the short end of the clamping block 2 contacts the limiting post 3, the counterweight 23 can keep the long end of the entire clamping block 2 in the anti-drop open state under the action of gravity.

[0018] Furthermore, the clamping block 2 is also equipped with a counterweight block 23, which is disposed at the counterweight end 22 of the clamping block 2.

[0019] Furthermore, the counterweight 23 has a cylindrical structure. The counterweight 23 is fixed to the short end side of the clamping block 2 by fasteners.

[0020] Furthermore, such as Figure 3 and Figure 4 As shown, the middle part of the clamping block 2 is rotatably connected to the base 1 by a locking screw 4.

[0021] In addition, this utility model also claims protection for a tooling fixture, including a base plate, wherein the base plate is equipped with any of the above-mentioned auxiliary anti-drop devices.
