Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment processing technology, specifically a fixing fixture for mechanical equipment processing. Background Technology

[0002] A machining fixture is an important tool used to fix a workpiece during machining to ensure machining accuracy and efficiency.

[0003] According to the authorized publication number CN218225633U, this invention belongs to the field of clamping technology, specifically a workpiece clamping structure for machining mechanical equipment. Addressing the issue that conventional workpiece clamping structures for machining mechanical equipment lack positioning mechanisms, resulting in low clamping tightness, this invention proposes the following solution: The structure includes a housing. Two circular grooves are formed on the inner walls of both sides of the housing. A single bidirectional threaded rod is rotatably mounted within the two circular grooves located on the same horizontal axis. Two movable plates are threaded onto the outer sides of the two bidirectional threaded rods. A bent plate is fixedly mounted on the top of each movable plate. This invention features a reasonable structural design. Through the threaded transmission between the bidirectional threaded rods and the movable plates, and the transmission cooperation between the worm gear and the worm wheel, the rotation of the turntable causes the two clamping plates to move closer together, achieving workpiece positioning. Furthermore, the engagement of the pin with the turntable restricts the rotation of the turntable, improving clamping stability and ensuring high reliability.

[0004] Based on the search of the aforementioned patents and the discovery of existing equipment, it is found that, when applied, the aforementioned equipment can solve the problem that conventional mechanical equipment processing workpiece clamping structures lack positioning structures, resulting in low clamping tightness.

[0005] In practical use, the clamping part of the above-mentioned equipment is designed to be fixed. This design choice brings significant limitations. Specifically, it means that the equipment can only effectively clamp and fix workpieces with planar features. However, in the modern machining environment, the shapes and sizes of workpieces are diverse, and cylindrical workpieces are a common type. When faced with such cylindrical workpieces, traditional fixed clamping methods are inadequate and cannot provide the same stable and effective clamping effect. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a fixed fixture for machining equipment, which has the advantage of adjustment. It solves the problem that the clamping part design of the above-mentioned equipment can only effectively clamp and fix workpieces with planar features. When facing cylindrical workpieces, the traditional fixed clamping method is inadequate and cannot provide the same stable and effective clamping effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fixed fixture for machining mechanical equipment, comprising a machining table, a bidirectional lead screw, a limiting rod, and a movable plate. The bidirectional lead screw is movably connected to the top and bottom of the machining table. The movable plate is threadedly connected to the left and right sides of the surface of the bidirectional lead screw. The limiting rod is slidably connected inside the movable plate. A mounting block is fixedly connected to the top of the movable plate. Movable rods are fixedly connected to the front and rear sides of the inner top of the mounting block. A clamping plate is movably connected to the surface of the movable rod. An adjustment mechanism is fixedly connected to the outer side of the clamping plate.

[0008] In a preferred embodiment of this utility model, the adjustment mechanism includes an adjustment block, which is fixedly connected to the outside of the clamping plate. An adjustment frame is movably connected to the outside of the adjustment block via a pivot pin, and a transmission component is provided inside the adjustment frame.

[0009] As a preferred embodiment of this utility model, the transmission component includes a threaded hole, which is located inside the adjustment frame, and a screw is threadedly connected to the inside of the threaded hole.

[0010] As a preferred embodiment of this invention, a support plate is movably connected to the inner side of the screw surface via a bearing, and the bottom of the support plate is fixedly connected to the mounting block.

[0011] As a preferred embodiment of this utility model, a positioning plate is fixedly connected to the outer side of the top of the mounting block, and the positioning plate is used in conjunction with the clamping plate.

[0012] As a preferred embodiment of this invention, a screwing block is fixedly connected to the outer end of the screw, and the screwing block is used to operate the screw.

[0013] As a preferred embodiment of this invention, the surface of the twisting block is provided with anti-slip grooves, and the anti-slip grooves are provided in a plurality of them and are distributed at equal intervals.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by setting up an installation block, a movable rod, a clamping plate, and an adjustment mechanism, allows the clamping plate to move inward when it is needed to clamp a cylindrical workpiece. The adjustment mechanism controls the clamping plate to rotate into a V-shape via the movable rod, thereby enabling the clamping plate to clamp the cylindrical workpiece. Simultaneously, when clamping a planar workpiece, the workpiece can be reset simply by adjusting the mechanism. This ensures that the clamping plate can adapt to different workpieces, improving clamping versatility. It solves the problem that the clamping design of the aforementioned equipment can only effectively clamp and fix workpieces with planar features, while traditional fixed clamping methods are inadequate for cylindrical workpieces, failing to provide the same stable and effective clamping effect. This invention achieves the desired adjustment effect.

[0016] 2. By setting an adjustment mechanism, when the operator needs to clamp the cylindrical workpiece with the clamping plate, the operator controls the adjustment frame to move inward through the transmission component. This causes the adjustment frame to drive the clamping plate to rotate inward through the movable rod via the adjustment block, so that the two clamping plates form a V-shape. This allows the clamping plate to adapt to the cylindrical workpiece, ensuring the operator's convenience in adjusting the clamping plate.

[0017] 3. By setting up a transmission component, this utility model allows the operator to adjust the clamping plate more precisely by rotating a screw and moving the adjusting frame through a threaded hole. Attached Figure Description

Detailed Implementation

[0023] 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.

[0024] like Figures 1 to 4 As shown, the present invention provides a fixed fixture for machining mechanical equipment, including a machining table 1, a bidirectional lead screw 2, a limiting rod 3, and a movable plate 4. The bidirectional lead screw 2 is movably connected to the top and bottom of the machining table 1. The movable plate 4 is threadedly connected to the left and right sides of the surface of the bidirectional lead screw 2. The limiting rod 3 is slidably connected inside the movable plate 4. A mounting block 5 is fixedly connected to the top of the movable plate 4. Movable rods 6 are fixedly connected to the front and rear sides of the inner side of the top of the mounting block 5. A clamping plate 7 is movably connected to the surface of the movable rod 6. An adjustment mechanism 8 is fixedly connected to the outer side of the clamping plate 7.

[0025] refer to Figure 4 The adjustment mechanism 8 includes an adjustment block 81, which is fixedly connected to the outside of the clamping plate 7. An adjustment frame 82 is movably connected to the outside of the adjustment block 81 via a shaft pin. A transmission assembly 83 is provided inside the adjustment frame 82.

[0026] As a technical optimization of this utility model, by setting an adjustment mechanism 8, when the operator needs the clamping plate 7 to clamp the cylindrical workpiece, the operator controls the adjustment frame 82 to move inward through the transmission component 83, so that the adjustment frame 82 drives the clamping plate 7 to rotate inward through the movable rod 6 via the adjustment block 81, so that the two clamping plates 7 form a V shape, thereby adapting the clamping plate 7 to the cylindrical workpiece and ensuring the convenience of the operator to adjust the clamping plate 7.

[0027] refer to Figure 4 The transmission component 83 includes a threaded hole 831, which is located inside the adjusting frame 82. A screw 832 is threadedly connected inside the threaded hole 831.

[0028] As a technical optimization of this utility model, by setting a transmission component 83, the screw 832 is rotated and driven to move the adjustment frame 82 through the threaded hole 831, thereby enabling the operator to adjust the clamping plate 7 more accurately.

[0029] refer to Figure 4 The inner side of the screw 832 is movably connected to the support plate 9 via a bearing, and the bottom of the support plate 9 is fixedly connected to the mounting block 5.

[0030] As a technical optimization of this utility model, by setting a support plate 9, the support plate 9 provides an additional support point for the screw 832, increasing the stability of the entire structure. This design can effectively prevent the screw 832 from bending or breaking during operation, improving the safety and reliability of the equipment. The support plate 9 can help distribute the pressure borne by the screw 832 and avoid damage caused by excessive local stress.

[0031] refer to Figure 4 A positioning plate 10 is fixedly connected to the outer side of the top of the mounting block 5. The positioning plate 10 is used in conjunction with the clamping plate 7.

[0032] As a technical optimization of this utility model, by setting a positioning plate 10, when the operator controls the clamping plate 7 to clamp the flat workpiece through the adjustment mechanism 8, the operator only needs to move the clamping plate 7 to fit with the positioning plate 10, thereby enabling the operator to quickly complete the adjustment of the clamping plate 7.

[0033] refer to Figure 4The outer end of the screw 832 is fixedly connected to a screwing block 11, which is used to operate the screw 832.

[0034] As a technical optimization of this utility model, by setting a screwing block 11, the operator can easily rotate the screw 832 manually. This design improves the operator's experience and work efficiency.

[0035] refer to Figure 4 The surface of the rotating block 11 is provided with anti-slip grooves 12, and there are several anti-slip grooves 12 distributed at equal intervals.

[0036] As a technical optimization of this utility model, by setting the anti-slip groove 12, the presence of the anti-slip groove 12 increases the friction between the hand and the twisting block 11, so that a good grip can be maintained even when there is sweat or other liquid on the hand.

[0037] The working principle and usage process of this utility model are as follows: When the operator needs to clamp a cylindrical workpiece, they rotate the rotating block 11 forward, causing the rotating block 11 to drive the screw 832 to rotate forward through the support plate 9. The rotating screw 832 will drive the adjusting frame 82 to move inward through the threaded hole 831. The adjusting frame 82 will then drive the clamping plate 7 to move through the adjusting block 81. The moving clamping plate 7 will then rotate inward through the restriction of the movable rod 6, forming a V-shape. After this V-shape is formed, the operator places the cylindrical workpiece in the middle of the top of the processing table 1. The operator then rotates the bidirectional lead screw 2, causing the bidirectional lead screw 2 to drive the two clamping plates through the limit rod 3. The movable plates 4 move closer together, causing the mounting block 5 and the V-shaped clamping plate 7 formed on top to move closer together, enabling the clamping plate 7 to clamp and fix the cylindrical workpiece, ensuring the adaptability of the clamping. Similarly, when the operator needs to use the clamping plate 7 to clamp the flat workpiece, the operator rotates the screw 832 in the opposite direction, causing the screw 832 to drive the adjusting frame 82 to move in the opposite direction, thereby causing the adjusting frame 82 to drive the clamping plate 7 to flip in the opposite direction via the adjusting block 81 and the movable rod 6. As long as the clamping plate 7 is moved to fit with the positioning plate 10, the clamping plate 7 can clamp and fix the flat workpiece again, thus ensuring that the clamping plate 7 can clamp and fix both flat and cylindrical workpieces.

[0038] In summary, this mechanical equipment processing fixture, through the arrangement of mounting block 5, movable rod 6, clamping plate 7, and adjustment mechanism 8, allows the clamping plate 7 to move inward when clamping a cylindrical workpiece. The adjustment mechanism controls the clamping plate 7 to rotate in a V-shape via the movable rod 6, enabling it to clamp the cylindrical workpiece. Simultaneously, when clamping a planar workpiece, the adjustment mechanism 8 simply resets the workpiece, ensuring that the clamping plate 7 can adapt to different workpieces, improving clamping versatility. This solves the problem that the clamping design of the aforementioned equipment can only effectively clamp and fix workpieces with planar features, while traditional clamping methods are inadequate for cylindrical workpieces, failing to provide the same stable and effective clamping effect.
