Description

Technical Field

[0001] This utility model relates to the field of CNC machining technology, specifically a tooling fixture for CNC machining. Background Technology

[0002] Generally, CNC machining refers to precision machining controlled by computer digital control, such as CNC lathes, CNC milling machines, and CNC boring and milling machines. CNC is also called computer-controlled milling machine. Its main function is to program machining, that is, to convert manual work into computer programming. Because CNC machining has high precision, its parts need to be well protected and stored during machining.

[0003] An investigation revealed that a Chinese utility model or invention patent discloses a workpiece storage rack for CNC machining (publication number: CN213796450U), comprising a base plate, a tray a, a tray b, and a tray c. Side plates are fixedly mounted on the upper sides of both sides of the base plate. A sliding groove is provided on the inner side of each side plate, and the sliding groove is slidably connected to tray a. A slider is fixedly connected to the side of tray a, and the slider and the sliding groove are mutually limited and slidably connected. A support frame is provided inside tray a, and a roller is mounted on the support frame, with the roller and support frame being rotatably connected. A rubber pad a is provided on the outer surface of the roller. A rotating bracket a and a rotating bracket b are fixedly connected to the lower ends of tray a, respectively. A light a is fixedly mounted on the inner side of the side plate between tray a and tray b, and a light b is fixedly mounted on the inner side of the side plate between tray b and tray c. This workpiece storage rack for CNC machining is simple to operate, convenient to use, and labor-saving.

[0004] Although the aforementioned patent makes the CNC machining workpiece storage rack simple to operate, easy to retrieve, and labor-saving through the setting of components such as the base plate, tray a, and tray b, most existing workpiece racks are open. When moving the workpiece rack, if the shaking amplitude is too large, the materials stored inside the workpiece rack will fall out, causing economic losses.

[0005] Therefore, this utility model provides a tooling fixture for CNC machining to solve the above problems. Summary of the Invention

[0007] This utility model provides a tooling fixture for CNC machining, which aims to solve the problems mentioned in the background art.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, the present invention provides the following technical solution: a CNC machining fixture, comprising a fixture mechanism, wherein the fixture mechanism comprises a base plate, a support leg is fixedly connected to the bottom of the base plate, a support rod is fixedly connected to the top of the base plate, and a top plate is fixedly connected to the end of the support rod away from the base plate;

[0010] The tooling frame mechanism is equipped with a protective device on its exterior. The protective device includes a fixed rod, which is fixedly connected to the side of the top plate away from the support rod. A motor is fixedly connected to the end of the fixed rod away from the top plate. A rotating rod is fixedly connected to the output shaft of the motor. A long plate passes through the end of the rotating rod away from the motor and is fixedly connected to the long plate.

[0011] As a preferred technical solution of this application, a short rod A passes through one end of the long plate and is fixedly connected to the short rod A. A connecting plate passes through the end of the short rod A away from the long plate and is rotatably connected to the connecting plate.

A slider is fixedly connected to the end of the short rod B away from the connecting plate. A sliding sleeve is fixedly connected to one side of the motor. A torsion spring rod is rotatably connected to the inner wall of the sliding sleeve. A pull rope is wound around the outer surface of the torsion spring rod. One end of the pull rope is fixedly connected to one side of the slider. A protective plate is fixedly connected to the other end of the pull rope. A lead screw A is fixedly connected to one side of the protective plate.

[0012] As a preferred technical solution of this application, the number of support legs is two, and they are symmetrical to each other along the vertical central axis of the base plate. The number of base plates is two, and they are arranged in a linear array on one side of the support rod.

[0013] As a preferred technical solution of this application, the tooling frame mechanism is provided with a limiting mechanism on its exterior. The limiting mechanism includes a positioning rod A, one end of which is fixedly connected to one end of a lead screw A. A gear A passes through the end of the positioning rod A away from the lead screw A and is fixedly connected to the gear A. A lead screw B is rotatably connected to one side of the base plate.

[0017] (III) Beneficial Effects

[0018] 1. This application achieves the goal of rotating the motor-driven rotating rod in coordination with components such as the fixed rod, long plate, and short rod A. The rotating rod is driven by the motor to rotate, which in turn drives the long plate to rotate. This causes the long plate to move the slider horizontally within the sliding sleeve, thereby causing the slider to lift the two anti-slip plates. This prevents the materials stored inside the workpiece rack from falling out due to excessive shaking during workpiece handling, thus avoiding economic losses.

[0019] 2. This application utilizes the force of the lead screw A's rotation in conjunction with components such as the positioning rod A, gear A, and lead screw B to achieve the effect of the lead screw A driving the positioning rod A to rotate, which in turn drives the gear A to rotate, which in turn drives the gear B to rotate, thereby causing the limit plate to come into contact with the top plate. This achieves the effect of secondary protection for the materials inside the workpiece holder, resulting in better protection. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides a tooling fixture for CNC machining, such as Figure 1 and Figure 3 As shown, the CNC machining fixture includes a fixture mechanism 1.

The end of the rotating rod 203 away from the motor 202 passes through a long plate 204 and is fixedly connected to the long plate 204.

[0030] like Figures 2-5As shown, a short rod A205 passes through one end of a long plate 204 and is fixedly connected to the short rod A205. A connecting plate 206 passes through the end of the short rod A205 away from the long plate 204 and is rotatably connected to the connecting plate 206. A short rod B207 passes through the end of the connecting plate 206 away from the short rod A205 and is rotatably connected to the short rod B207. A slider 208 is fixedly connected to the end of the short rod B207 away from the connecting plate 206. A sliding sleeve 209 is fixedly connected to one side of the motor 202. A torsion spring rod 210 is rotatably connected to the inner wall of the sliding sleeve 209. A pull rope 211 is wound around the outer surface of the torsion spring rod 210. One end of the pull rope 211 is fixedly connected to one side of the slider 208. A protective plate 212 is fixedly connected to the other end of the pull rope 211. A lead screw A213 is fixedly connected to one side of the protective plate 212.

[0031] like Figure 1 As shown, there are two support legs 102, which are symmetrical to each other along the vertical central axis of the base plate 101. There are two base plates 101, which are arranged in a linear array on one side of the support rod 103.

[0032] like Figure 2 and Figure 4 As shown, a limiting mechanism 3 is provided on the outside of the tooling frame mechanism 1. The limiting mechanism 3 includes a positioning rod A301. One end of the positioning rod A301 is fixedly connected to one end of the lead screw A213. The end of the positioning rod A301 away from the lead screw A213 passes through a gear A302 and is fixedly connected to the gear A302. A lead screw B303 is rotatably connected to one side of the base plate 101. A limiting plate 304 is fixedly connected to the circumferential surface of the lead screw B303. A positioning rod B305 is fixedly connected to one end of the lead screw B303. The end of the positioning rod B305 away from the lead screw B303 passes through a gear B306 and is fixedly connected to the gear B306.

[0033] like Figure 4 As shown, there are four positioning rods A301, arranged in pairs and symmetrical to each other along the vertical central axis of the base plate 101. Gear A302 and gear B306 mesh with each other.

[0034] like Figure 2 and Figure 4 As shown, there are two limiting plates 304, which are symmetrical to each other along the vertical central axis of the bottom plate 101, and the side of the top plate 104 is located on the displacement trajectory of the limiting plate 304.

[0035] like Figures 2-3 As shown, the slider 208 is slidably connected to the inner wall of the sleeve 209, the circumferential surface of the lead screw A213 is rotatably connected to one side of the base plate 101, and there are two connecting plates 206, which are symmetrical about the center point of the rotating rod 203.

[0036] The principle of this utility model is as follows: An external power source drives the motor 202, which in turn drives the rotating rod 203 to rotate. The rotating rod 203 then drives the long plate 204 to rotate, which in turn drives the short rod A205 in a circular motion. The short rod A205 then drives the connecting plate 206 in a circular motion, which in turn drives the short rod B207 in a circular motion. The short rod B207 then drives the slider 208 in a circular motion. Because the slider 208 is limited by the sliding sleeve 209 during its circular motion, it moves horizontally within the sleeve. This causes the slider 209 to pull the pull rope 211, which in turn, via the torsion spring rod 210, pulls the protective plate 212, causing it to move. At this point, the protective plate 212... The lead screw A213 rotates to prevent materials stored inside the workpiece rack from falling due to excessive shaking during workpiece handling, thus avoiding economic losses. When the lead screw A213 rotates, it drives the positioning rod A301 to rotate, which in turn drives the gear A302 to rotate. This gear A302 then drives the gear B306 to rotate, which in turn drives the positioning rod B305 to rotate. This, in turn, drives the lead screw B303 to rotate, which in turn drives the limiting plate 304 to rotate. This causes the limiting plate 304 to come into contact with the side of the top plate 104, thus achieving a secondary protection effect for the materials inside the workpiece rack, making the protection more effective.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
