Description

Technical Field

[0001] This utility model relates to the field of lathe fixture technology, specifically a lathe fixture that is easy to install. Background Technology

[0002] Lathe fixtures are used on lathes to machine the internal and external rotating surfaces and end faces of workpieces. Most lathe fixtures are mounted on the spindle, while a few are mounted on the saddle or bed. Lathe fixtures are classified according to the workpiece positioning method as follows: centering type (mandrel type), chuck type, collet type, angle iron type, and faceplate type, etc. Fixtures are devices used in mechanical manufacturing processes to fix the workpiece in the correct position for construction or inspection. In a broad sense, any device used to quickly, conveniently, and safely install a workpiece in any step of the process can be called a fixture.

[0003] An investigation revealed that a Chinese utility model patent discloses an easy-to-install CNC lathe fixture (publication number: CN222307384U), which includes a base. The base is movably connected to two locking blocks. A vertical block is fixedly connected to one side of each of the two locking blocks. A material clamp is movably connected to the outer side of each of the two vertical blocks. A slider is fixedly connected to the top of each of the two vertical blocks. The same material clamp is slidably connected to the outer side of each of the two sliders. A spring is fixedly connected to one side of each of the two vertical blocks.

[0004] While the aforementioned patent facilitates the assembly and disassembly of the material clamp and base through locking blocks, and allows for easy movement of the vertical block through threaded rods and transverse blocks, thereby increasing the efficiency of material clamp replacement, the throttle of this device is independently set. Since the throttle driving the transverse block is not fixedly connected to the base, operators need to perform additional alignment operations between the cross block and the slot in the base. Compared to the structure of directly driving the slider, this significantly increases the operational complexity. Furthermore, after the operation is completed, the throttle and its connecting parts need to be disassembled, which not only increases the maintenance workload but also poses a risk of loss or damage to key components. If the throttle assembly is lost or damaged, the entire clamp replacement system will completely lose its functional reliability, seriously affecting the continuous operating efficiency of the equipment.

[0005] Therefore, this utility model provides a lathe fixture that is easy to install, in order to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: It includes a base and a clamp body. Multiple slots are provided on the side wall of the clamp body. A limiting mechanism is provided within the side wall of the base. The limiting mechanism includes multiple screws, sliders, and multiple locking blocks. Each locking block is adapted to one of the multiple slots. The sliders are threadedly connected to the screws. A support plate is slidably connected within the base. An adjustment mechanism is provided between the support plate and the base. The adjustment mechanism includes a lead screw, symmetrically arranged mounting blocks, and connecting rods. Both mounting blocks are threadedly connected to the lead screw.

[0010] As a preferred technical solution of this application, a cavity is provided in the side wall of the base, the screw is rotatably connected in the cavity, and a movable plate is symmetrically fixed on the side wall of the slider. The movable plate slides through the side wall of the cavity and is fixedly connected to the locking block.

[0011] As a preferred technical solution of this application, gears are coaxially fixed on multiple screws, and a toothed ring is rotatably connected in the cavity, with the toothed ring meshing with multiple gears.

[0012] As a preferred technical solution of this application, the lead screw is rotatably connected to the base, both mounting blocks are slidably connected to the base, mounting platforms are fixedly connected to the support plate and the mounting blocks, and both ends of the connecting rod are rotatably connected to the mounting platforms.

[0013] As a preferred technical solution of this application, a second knob is rotatably connected to the side wall of the base, and the second knob is fixed coaxially with the lead screw.

[0014] As a preferred technical solution of this application, a plurality of first knobs are rotatably connected to the side wall of the base, and the plurality of first knobs are respectively coaxially fixed with a plurality of screws.

[0015] (III) Beneficial Effects

[0016] The clamp body is fixed on the base by setting a limiting mechanism. Rotating the first knob drives the limiting mechanism to operate, so that multiple blocks in the limiting mechanism are inserted into multiple slots on the clamp body, thereby quickly installing the clamp body. Reversing the first knob can remove the blocks from the slots and release the clamp body from the limiting position. The operation is simple and convenient. Then, by adjusting the linkage in the mechanism, the support plate is pushed to move, so that the support plate abuts against the clamp body, improving the installation stability of the clamp body.

[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] This utility model provides a lathe fixture that is easy to install, such as... Figures 1-4 As shown, the technical solution includes a base 1 and a clamp body 2. Multiple slots 5 are provided on the side wall of the clamp body 2. A limiting mechanism is provided inside the side wall of the base 1. The limiting mechanism includes multiple screws 11, sliders 12, and multiple locking blocks 6. The multiple locking blocks 6 are respectively adapted to the multiple slots 5. The sliders 12 are threadedly connected to the screws 11. The clamp body 2 is limited on the base 1 by the locking blocks 6 in the limiting mechanism. A support plate 7 is slidably connected inside the base 1. An adjustment mechanism is provided between the support plate 7 and the base 1. The adjustment mechanism includes a lead screw 14, symmetrically arranged mounting blocks 15, and a connecting rod 8. Both mounting blocks 15 are threadedly connected to the lead screw 14. The connecting rod 8 in the adjustment mechanism pushes the support plate 7 to move, causing the support plate 7 to abut against the clamp body 2, thereby improving the installation stability of the clamp body 2.

[0025] A cavity is provided in the side wall of the base 1. The screw 11 is rotatably connected in the cavity. A movable plate 13 is symmetrically fixed on the side wall of the slider 12. The movable plate 13 slides through the side wall of the cavity and is fixedly connected to the locking block 6. A gear 10 is coaxially fixed on each of the screws 11. A gear ring 9 is rotatably connected in the cavity, and the gear ring 9 meshes with the multiple gears 10. A multiple first knobs 3 are rotatably connected on the side wall of the base 1, and the multiple first knobs 3 are coaxially fixed to the multiple screws 11 respectively.

[0026] In use, rotating any one of the first knobs 3 drives the coaxially fixed gear 10 and screw 11 to rotate. The rotating gear 10 drives the other gears 10 to rotate synchronously through the gear ring 9, which in turn drives the screws 11 to rotate synchronously. The rotating screws 11 drive the slider 12 to move. The slider 12 drives the locking block 6 to move through the moving plate 13, pushing the locking block 6 into the slot 5, thereby limiting and fixing the fixture body 2, realizing the quick installation of the fixture body 2. Reversing the first knob 3 can remove the locking block 6 from the slot 5, releasing the limitation on the fixture body 2. The operation is simple and convenient.

[0027] The lead screw 14 is rotatably connected to the base 1, and the two mounting blocks 15 are slidably connected to the base 1. Mounting platforms 16 are fixedly connected to the support plate 7 and the mounting blocks 15. Both ends of the connecting rod 8 are rotatably connected to the mounting platforms 16. A second knob 4 is rotatably connected to the side wall of the base 1. The second knob 4 is coaxially fixed with the lead screw 14.

[0028] When in use, turning the second knob 4 drives the lead screw 14 to rotate. The rotating lead screw 14 drives the two mounting blocks 15 to move in opposite directions. The mounting blocks 15 drive the connecting rod 8 to rotate through the mounting platform 16. The connecting rod 8 pushes the support plate 7 to move, adjusting the position of the support plate 7 so that when the clamp body 2 and the support plate 7 abut, the slot 5 on the clamp body 2 and the locking block 6 are in opposite positions. At the same time, the support plate 7 can support the clamp body 2, improving the installation stability of the clamp body 2.

[0029] In summary: During operation, rotating the second knob 4 drives the lead screw 14 to rotate. The rotating lead screw 14 drives the two mounting blocks 15 to move in opposite directions. The mounting blocks 15 drive the connecting rod 8 to rotate through the mounting platform 16. With the help of the connecting rod 8, the support plate 7 is moved and the position of the support plate 7 is adjusted so that when the clamp body 2 and the support plate 7 are in contact, the slot 5 on the clamp body 2 and the block 6 are in opposite positions.

[0030] Rotating any one of the first knobs 3 causes the coaxially fixed gear 10 and screw 11 to rotate. The rotating gear 10 drives the other gears 10 to rotate synchronously through the gear ring 9, which in turn drives the screws 11 to rotate synchronously. The rotating screws 11 drive the slider 12 to move. The slider 12 drives the locking block 6 to move through the moving plate 13, pushing the locking block 6 into the locking slot 5, thereby limiting and fixing the fixture body 2.

[0031] 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.
