[0002] Forging is a process of forming metal materials using pressure processing methods. It features energy saving and excellent product performance. In forging, materials with good plasticity and toughness, such as steel, iron, copper, and aluminum, are typically selected to withstand the pressure during forging. To ensure the stability of forging processing, positioning fixtures are required. The "High-Precision Positioning Fixture for Forging Processing with a Simple Structure" disclosed in application number "CN202121754838.1" is an increasingly mature technology. "During operation, the interaction of the base plate, support block, strip frame, adjustment mechanism, and positioning mechanism allows for better positioning of annular forgings of different diameters, facilitating better processing operations." However, this positioning fixture still has the following drawbacks during use:
[0003] This positioning fixture, with its base plate, support block, strip frame, and adjustment mechanism, can indeed position ring forgings of different diameters. However, the upper fixture has a simple structure, resulting in insufficient stability in its clamping effect. Therefore, it is necessary to provide a positioning fixture that improves positioning stability and enhances practicality. Furthermore, iron filings are generated during forging, posing a safety hazard. Therefore, it is necessary to provide a positioning fixture that provides protection. Utility Model Content
[0004] This utility model provides a positioning fixture for forging processing, aiming to solve the problem that the protective effect and positioning stability of existing positioning fixtures need to be improved.
[0005] To achieve the above objectives, this utility model provides a positioning fixture for forging processing, including a protective component and a positioning component;
[0006] The protective assembly includes a jig platform, with two first protective plates installed on the upper end of the jig platform.

Two hinge slots are opened on both sides of the jig platform. Two hinge shafts are fixedly connected to the lower ends of the two second protective plates. The two hinge shafts are hinged inside the hinge slots.
[0007] A positioning assembly includes a rotating shaft mounted on the lower end of a fixture table. Two hinge plates are fixedly connected to both sides of the rotating shaft. A transmission shaft is hinged between the two hinge plates. A connecting plate is hinged to the end of the transmission shaft. A positioning plate is fixedly mounted on the upper end of the connecting plate. A first bevel gear is detachably mounted on the lower end of the rotating shaft. A servo motor is mounted on the lower end of the fixture table. A second bevel gear is fixedly connected to the output end of the servo motor. The first bevel gear and the second bevel gear are meshed together.
[0008] As a preferred embodiment of this utility model, the upper end of the fixture table has two strip grooves, and the lower ends of the two first guard plates are fixedly connected to strip plates, which are snapped into the inside of the strip grooves.
[0009] As a preferred embodiment of this utility model, the inner wall of the second guard plate is fixedly connected with two clamping plates, and the opposite surfaces of the two first guard plates are fixedly connected with limiting strips. The upper end of the limiting strips has two slots, and the clamping plates are engaged inside the slots.

[0016] 2. When forging the workpiece, firstly, two first guard plates are installed on both ends of the upper surface of the fixture table. At this time, the second guard plates on both sides of the fixture table are controlled to rotate around the hinge axis and interlock with the two first guard plates, thereby covering the fixture table. The presence of transparent glass facilitates observation of the operation. The first guard plates and the second guard plates can limit the movement of iron chips. Compared with the positioning fixture in the existing technology "a high-precision positioning fixture for forging processing with a simple structure", this utility model significantly improves the safety of the positioning fixture through the cooperation of the above structures.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0025] Please see Figures 1-5 This utility model provides a positioning fixture for forging processing, including a protective component 100 and a positioning component 200;
[0026] The protective component 100 includes a jig table 101. Two first protective plates 102 are installed on the upper end of the jig table 101. Two second protective plates 103 are installed on both sides of the two first protective plates 102. Two transparent glass 104 are embedded inside the second protective plates 103. Two hinge slots 105 are opened on both sides of the jig table 101. Two hinge shafts 106 are fixedly connected to the lower end of the two second protective plates 103. The two hinge shafts 106 are hinged inside the hinge slots 105.
[0027] The positioning component 200 includes a rotating shaft 201 mounted on the lower end of the fixture table 101. Two hinge plates 202 are fixedly connected to both sides of the rotating shaft 201. A transmission shaft 203 is hinged between the two hinge plates 202. A connecting plate 204 is hinged to the end of the transmission shaft 203. A positioning plate 205 is fixedly mounted on the upper end of the connecting plate 204. A first bevel gear 206 is detachably mounted on the lower end of the rotating shaft 201. A servo motor 207 is mounted on the lower end of the fixture table 101. A second bevel gear 208 is fixedly connected to the output end of the servo motor 207. The first bevel gear 206 and the second bevel gear 208 are meshed together.
[0028] In one specific embodiment, the protective component 100, in conjunction with the positioning component 200, not only enables stable clamping and positioning of workpieces of different sizes, significantly enhancing the practicality of the positioning fixture, but also provides a protective enclosure for the fixture, preventing damage from flying metal filings. This improves the safety of the positioning fixture. In use, the workpiece is first placed on the upper end of the fixture table 101. Then, the second guard plate 103 is rotated around its hinge shaft 106, causing the two second guard plates 103 and the first guard plate 102 to engage with each other, thus providing a protective enclosure for the fixture table 101. The cover is then activated, and the servo motor 207 drives the second bevel gear 208 to rotate, which in turn drives the first bevel gear 206 and its upper shaft 201 to rotate. By rotating the hinge plates 202 on both sides of the shaft 201, the transmission shaft 203 can be pulled, which controls the two connecting plates 204 and the positioning plate 205 to move closer to each other, thereby enabling the workpiece to be clamped and positioned. During workpiece processing, the transparent glass 104 on the surface of the first guard plate 102 and the second guard plate 103 facilitates observation. At the same time, the above structures work together to facilitate stable positioning of the workpiece, thereby enhancing the practicality of the positioning fixture.
[0029] Please see Figure 3 and Figure 4 The upper end of the fixture table 101 has two strip grooves 111, and the lower ends of the two first guard plates 102 are fixedly connected to strip plates 112, which are snapped into the inside of the strip grooves 111.
[0030] In one specific embodiment, the strip plate 112 is snapped into the strip groove 111, which can facilitate the easy assembly and disassembly of the first guard plate 102.
[0031] Please see Figure 3 and Figure 4 The inner wall of the second guard plate 103 is fixedly connected with two clamping plates 121. The opposite surfaces of the two first guard plates 102 are fixedly connected with limit strips 122. The upper end of the limit strips 122 has two slots 123, and the clamping plates 121 are engaged inside the slots 123.
[0032] In one specific embodiment, the card plate 121 is snapped into the slot 123, which can improve the installation stability and tightness between the second guard plate 103 and the first guard plate 102.
[0033] Please see Figure 3 and Figure 4 The upper end of the fixture platform 101 has two guide grooves 131.
[0034] In one specific embodiment, the guide groove 131 is used to guide the positioning plate 205.
[0035] Please see Figure 5 Two hinge pieces 211 are fixedly connected to the opposite surfaces of the two connecting plates 204, and the two hinge pieces 211 are hinged to one end of the drive shaft 203.
[0036] In one specific embodiment, the hinge plate 211 and the drive shaft 203 are hinged to each other, which facilitates the control of the tilt of the drive shaft 203 to pull the positioning plate 205.
[0037] Please see Figure 5 A limiting hole 221 is provided at the lower end of the rotating shaft 201, and a limiting shaft 222 is fixedly connected to the upper end of the first bevel gear 206. The limiting shaft 222 is inserted into the inside of the limiting hole 221.
[0038] In one specific embodiment, the limiting shaft 222 is inserted into the limiting hole 221, which can improve the ease of disassembly and assembly between the first bevel gear 206 and the rotating shaft 201.
[0039] Please see Figures 3-5 Two guide blocks 231 are fixedly connected between the connecting plate 204 and the positioning plate 205, and both guide blocks 231 are slidably connected inside the guide groove 131.
[0040] In one specific embodiment, the guide block 231 moves along the guide groove 131 to guide the connecting plate 204 and help improve the clamping stability of the positioning plate 205 on the workpiece.
[0041] Working principle: In use, the workpiece is first placed on the upper end of the fixture table 101. Then, the second guard plate 103 is rotated around the hinge shaft 106, causing the two second guard plates 103 and the first guard plate 102 to engage with each other, thus covering the fixture table 101. Next, the servo motor 207 is started to rotate the second bevel gear 208, which in turn rotates the first bevel gear 206 and its upper shaft 201. By rotating the hinge plates 202 on both sides of the shaft 201, the transmission shaft 203 is pulled, which controls the two connecting plates 204 and the positioning plate 205 to move closer together, so as to clamp and position the workpiece. During workpiece processing, the transparent glass 104 on the surface of the first guard plate 102 and the second guard plate 103 facilitates observation. At the same time, the above structure also facilitates stable positioning of the workpiece, thus enhancing the practicality of the positioning fixture.
