Description

Technical Field

[0001] This utility model relates to the field of turning fixture technology, and in particular to an adjustable turning fixture support frame for irregularly shaped products. Background Technology

[0002] Turning, also known as lathe machining, is a common machining method in the machinery manufacturing industry. Lathe machining primarily involves using a cutting tool to turn a rotating workpiece. Drills, reamers, taps, dies, and knurling tools can also be used on a lathe for further machining.

[0003] To accommodate the growing demand for clamping irregularly shaped workpieces, existing turning fixtures have been designed. For example, Chinese Utility Model Publication No. CN216781037U discloses a lathe turning fixture for irregularly shaped workpieces, relating to the field of turning fixture technology. Through the arrangement of clamping and supporting components, it can clamp irregular workpieces, meeting diverse usage needs, offering strong practicality and high stability, thus improving safety performance. Another Chinese Utility Model Publication No. CN214134923U discloses a turning fixture for irregularly shaped parts, utilizing a clamping device to hold the irregularly shaped parts and a backing device to provide auxiliary support, resulting in fast clamping speed and stable clamping.

[0004] However, all of the aforementioned turning fixtures for irregularly shaped products share a common drawback: the turning fixtures are fixedly mounted on support frames, and the height of these support frames is constant. This makes it inconvenient to adjust the height of the product held in the turning fixture during processing. In addition, the processing position of the current turning fixtures is also fixed, making it inconvenient to move and adjust the turning fixtures during use to meet the needs of different processing operations.

[0005] Therefore, to address the above problems, an adjustable turning fixture support frame for irregularly shaped products is proposed. Utility Model Content

[0006] In view of the above-mentioned technical problems, this utility model provides an adjustable turning fixture support frame for irregularly shaped products. The height of the fixture assembly can be adjusted by designing a height adjustment mechanism, and the horizontal position of the fixture assembly can be adjusted by adding a moving adjustment mechanism, thereby meeting more processing needs in the turning process.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] An adjustable turning fixture support frame for irregularly shaped products includes a base, a mounting frame, and a fixture assembly. The mounting frame is located above the base, and the fixture assembly is mounted on the mounting frame. The base is mounted on a movable adjustment mechanism, and height adjustment mechanisms are respectively located at both ends of the base. Each height adjustment mechanism is connected to the mounting frame, and the fixture assembly is installed between two mounting frames.

[0009] The movable adjustment mechanism consists of a fixed base, a lead screw, an operating wheel, and a movable block. The lead screw is installed in the movable groove on the fixed base via a bearing. One end of the lead screw passes through the groove wall and extends out to connect with the operating wheel. The movable block is threaded onto the lead screw, and a base is fixedly installed on top of the movable block.

[0010] The base has sliders at both ends below it. The sliders are slidably connected to the slide rail, which is fixed to the fixed base.

[0011] The height adjustment mechanism consists of a support frame, a motor, a gear, and a rack. The support frame is fixed to the base. One end of the mounting bracket is located inside the support frame, and the T-shaped strips on both sides of the mounting bracket are connected to the T-shaped grooves on the support frame. The rack is fixed to the side of the mounting bracket and meshes with the gear. The gear has a central shaft. One end of the central shaft is connected to the output end of the motor, and the other end of the central shaft is mounted on the support frame through a bearing.

[0012] The clamp assembly consists of a fixing block and limiting parts. The fixing block is fixedly connected to the mounting frame and has positioning holes. Multiple sets of limiting parts are arranged at intervals around the outer ring of the positioning holes on the fixing block.

[0013] The limiting part includes a mounting base, an adjusting screw, and a positioning plate. The mounting base is fixed to the fixing block by bolts. The adjusting screw is internally threaded through a threaded hole on the mounting base. The positioning plate is installed at the end of the adjusting screw.

[0014] Furthermore, the motor is fixedly mounted on the support frame via a motor mount, and the two motors are electrically connected to an external controller via wires, so that the controller can control the two motors to run simultaneously.

[0015] The beneficial effects of this utility model are:

[0016] This utility model achieves height adjustment of the mounting frame by designing a height adjustment mechanism, that is, adjusts the height of the product clamped in the fixture assembly. The height adjustment mechanism is controlled by a controller to operate the motors in two sets of height adjustment mechanisms simultaneously. The motor drives the gear to rotate, and the meshing transmission between the gear and the rack causes the rack to move up and down, thus achieving height adjustment of the mounting frame and meeting more usage needs when turning products.

[0017] This invention achieves horizontal movement of the entire fixture assembly by adding a moving adjustment mechanism. The operator rotates the operating wheel, causing the lead screw to rotate and the moving block threaded onto the lead screw to move axially, thereby driving the entire fixture assembly to move and adjust the turning fixture.

Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] Example 1

[0027] As shown in the figure, a mounting bracket 5 is provided above the base 1, and a clamping assembly for processing irregularly shaped products is installed between the two mounting brackets 5. The clamping assembly is an existing structure, which consists of a fixing block 61 and multiple sets of limiting parts for positioning products. The fixing block 61 is fixedly installed on the mounting bracket 5. The fixing block 61 is provided with a positioning hole 611 for positioning products, and multiple sets of limiting parts are arranged at intervals around the outer ring of the positioning hole 611. The mounting seat 621 in the limiting part is fixed to the fixing block 61 by bolts. The threaded hole provided on the mounting seat 621 is internally threaded to the adjusting screw 622. The end of the adjusting screw 622 is installed with a positioning piece 623. In use, the product is placed in the positioning hole 611 of the positioning block 61, and by operating the adjusting screw 622 in each set of limiting parts, the positioning piece 623 moves to abut against the outer surface of the product to complete the clamping operation.

[0028] like Figure 2 and 3This application adds a movable adjustment mechanism, in which the base 1 is installed on the fixed seat 21 in the movable adjustment mechanism. The movable groove 211 provided on the fixed seat 21 is equipped with a lead screw 22 installed in the groove through a bearing. One end of the lead screw 22 passes through the groove wall of the movable groove 211 and extends out to connect with the operating wheel 24. The movable block 23 is threadedly connected to the lead screw 22. The base 1 is fixedly installed on the top of the movable block 23. The two ends below the base 1 are provided with a slide rail 31 and a slider 32 between the base 1 and the fixed seat 21. The slider 32 is fixed on the base 1, the slide rail 31 is fixed on the fixed seat 21, and the slider 32 is slidably connected to the slide rail 31.

[0029] like Figure 1 , 4 Height adjustment mechanisms are respectively provided at both ends above the base 1, and each height adjustment mechanism is connected to the mounting frame 5. One end of the mounting frame 5 extends into the support frame 41 of the height adjustment mechanism, and the T-shaped strips provided on both sides of the mounting frame 5 are connected to the T-shaped grooves 411 provided on the support frame 41. The rack 44 is fixed on the side of the mounting frame 5 and located inside the support frame 41. The rack 44 is meshed with the gear 43. The gear 43 is provided with a central shaft 431. One end of the central shaft 431 is connected to the output end of the motor 42, and the other end is mounted on the support frame 41 through a bearing.

[0030] In this case, the motors 42 in both height adjustment mechanisms are fixedly mounted on the support frame 41 via motor mounts, and the two motors 42 are electrically connected to an external controller via wires. The controller controls the two motors 42 to run simultaneously. It should be noted that using a controller to control the two motors 42 to run simultaneously is a mature existing technology, so it will not be described in detail here.

[0031] Example 2

[0032] In use, this utility model allows for the clamping and positioning of irregularly shaped products via a fixture assembly, after which the products can be processed.

[0033] When the height of the product needs to be adjusted, the controller controls the motors 42 in the two height adjustment mechanisms to run simultaneously. The motors 42 drive the gears 43 to rotate, and the meshing transmission between the gears 43 and the rack 44 causes the rack 44 to move up and down, thereby adjusting the height of the mounting frame 5, which in turn adjusts the height of the fixture assembly and meets more usage needs when turning the product.

[0034] When it is necessary to adjust the position of the fixture assembly in the horizontal direction, the operator rotates the operating wheel 24, causing the lead screw 22 to rotate. The moving block 23, which is threaded onto the lead screw 22, can only move axially back and forth, thereby driving the entire fixture assembly to move axially and realize the adjustment of the turning fixture.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. The various components mentioned in this utility model are common technologies in the existing field. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
