Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a fixing device for the production of machine tool parts. Background Technique

[0002] A machine tool refers to a machine that manufactures machines, also known as a mother machine or a tool machine, and is generally referred to as a machine tool for short. It is generally divided into metal cutting machine tools, forging machines, and woodworking machine tools, etc. There are many methods for machining mechanical parts in modern mechanical manufacturing: in addition to cutting, there are also casting, forging, welding, stamping, extrusion, etc. However, for parts with relatively high precision requirements and relatively fine surface roughness requirements, they generally need to be finally processed by cutting on a machine tool. Machine tools play a major role in the construction of national economic modernization.

[0003] The utility model patent with the publication number of CN215942198U discloses a machine tool fixing device that is easy to use, and relates to the technical field of machine tool fixing devices. The utility model includes a bottom plate and an operating table installed above the bottom plate. A plurality of first sliding grooves are circumferentially arranged on the upper side of the operating table, and a second sliding groove communicated with the first sliding groove is opened on the bottom surface of the operating table. A push plate is slidably matched in the first sliding groove, a pull plate is slidably matched in the push plate, and a cover plate elastically matched above the push plate is installed on the upper side of the pull plate.

[0004] There are still some problems in this prior art: 1. When fixing parts, the shapes of the parts are different, the clamping effect is unstable, the parts are prone to looseness and displacement, resulting in large errors during part processing, and the movement causes the clamping assembly to easily damage the parts when clamping, with low practicability and low processing efficiency.

[0005] 2. The device cannot adjust the height during clamping, so that the user cannot change the height of the fixture according to needs, resulting in inconvenience during processing. It can only be adjusted manually, and the levelness of the part after the height is adjusted cannot be guaranteed, thus affecting the processing accuracy. Content of the Utility Model

[0031] The present utility model will be further described in detail below with reference to the drawings.

[0032] Combined with the attached Figures 1 to 6 , a fixing device for machine tool part production mainly includes: upper plate 1, lower plate 3, fixing device 5, height adjustment device 6, support part

[0033] Among them, chutes 2 are opened at the front and rear ends and on both sides of the middle part of the upper plate 1. The lower plate 3 is arranged below the upper plate 1. Both the front and rear sides of the upper end of the lower plate 3 are connected to the upper plate 1 through fixedly connected support columns one 4.

[0034] Then, in order to fix irregular parts, fixing devices 5 are arranged at the front and rear ends and on both sides of the middle part of the upper plate 1. The fixing device 5 includes an H-shaped slider 9. The H-shaped slider 9 is slidably connected to the chute 2. On the mutually close side and the mutually far side of the upper end of the H-shaped slider 9, a fixing plate one 10 and a fixing plate two 11 are respectively fixedly connected. Not less than one threaded hole 25 is opened on both the fixing plate one 10 and the fixing plate two 11. A bolt 26 is threadedly connected in the threaded hole 25. A clamping block 12 is threadedly connected to the mutually close ends of the fixing plate one 10 through the bolt 26. There is a V-shaped notch on the mutually close side of the clamping block 12. Friction parts for increasing friction are evenly distributed in the V-shaped notch, which is convenient for clamping parts more firmly. When the clamping block 12 is used for a long time, wear will occur and the clamping effect will not be stable. The clamping block 12 can be disassembled through the bolt 26 for replacement.

[0035] Then, a protruding part 13 is fixedly connected to the lower end of the H-shaped slider 9. A support column two 14 is fixedly connected to the middle part of the upper end of the lower plate 3. The upper end of the support column two 14 is rotatably connected to a rotating plate 15. Four corners of the upper end of the rotating plate 15 are rotatably connected to V-shaped rods 16. One ends of the V-shaped rods 16 away from each other are rotatably connected to the protruding part 13. Fixing plates three 17 are fixedly connected to the lower ends of the protruding parts 13 at the front and rear ends. Two symmetrically arranged telescopic cylinders 18 are fixedly connected to the mutually close surfaces of the fixing plates three 17 at the front and rear ends. The telescopic cylinders 18 are arranged below the rotating plate 15.

[0036] When it is necessary to fix parts, the telescopic cylinders 18 on both sides retract. The H-shaped sliders 9 at the front and rear ends slide on the chute 2 in the direction of approaching each other. At the same time, the V-shaped rods 16 are pushed to rotate counterclockwise, driving the rotating plate 15 to rotate, pulling the V-shaped rods 16 on both sides to rotate, driving the H-shaped sliders 9 on both sides to slide on the chute 2 in the direction of approaching each other, clamping the parts placed on the upper plate 1, restricting the four directions of the irregular parts in four directions, and having a better fixing effect to prevent the parts from generating displacement during processing.

[0037] Next, in order to adjust the height of the parts, the height-adjusting device 6 is arranged at the front and rear ends of the upper plate 1, and the height-adjusting device 6 includes a screw rod 19, which is rotatably connected to one side of the support plate 7, and a threaded block 20 is rotatably connected to the screw rod 19. A guide column 21 is fixedly connected to the side of the support plate 7 away from the screw rod 19. The guide column 21 can ensure the stability and direction of the lower plate 3 when it moves up and down, and prevent the lower plate 3 from rotating when it moves up and down. A sleeve 22 is slidably connected to the guide column 21, and the sleeve 22 and the threaded block 20 are fixedly connected to the lower plate 3 on their respective surfaces close to each other. In order to provide rotation for the screw rod 19, a motor 23 is fixedly connected to the lower end of the support plate 7, and the output shaft of the motor 23 extends through the support plate 7 to above it and is fixedly connected to the screw rod 19. The upper ends of the screw rod 19 and the guide column 21 are fixedly connected to a limiting plate 24 to prevent the threaded block 20 from leaving the matching range of the screw rod 19 when moving upward.

[0038] Finally, the support part is used to support the lower plate 3 and the height adjustment device 6. The support part is arranged below the lower plate 3. The support part includes a support plate 7 and a support rod 8. The support plate 7 is arranged below the lower plate 3, and the support rod 8 is fixedly connected to the four corners of the lower end of the support plate 7.

[0039] It should be noted here that the electrical components appearing in this article are all connected to the external main controller and 220V AC power, and the main controller can be a conventional known device that controls a computer, etc. The specific implementation method of the present disclosure omits the detailed description of known functions and known parts. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of marketed equipment.

[0040] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
