Description

Technical Field

[0001] This utility model relates to the field of chuck production and processing technology, specifically to a positioning and cutting device for chuck production and processing. Background Technology

[0002] A chuck is a mechanical device used on machine tools to clamp workpieces. It's a machine tool accessory that uses the radial movement of movable jaws evenly distributed on the chuck body to clamp and position the workpiece. A chuck generally consists of three parts: the chuck body, the movable jaws, and the jaw drive mechanism. The chuck body diameter ranges from a minimum of 65 mm to a maximum of 1500 mm, with a central through-hole to allow the workpiece or bar stock to pass through; the back has a cylindrical or short conical structure, directly or via a flange, connecting to the end of the machine tool spindle. Chucks are commonly used on lathes, external cylindrical grinding machines, and internal cylindrical grinding machines, and can also be used with various indexing devices on milling machines and drilling machines.

[0003] Before processing, the chuck needs to be cut into blanks of a certain size from the raw materials using a corresponding cutting device so that the chuck can be produced later.

[0004] The existing technology has the following problems:

[0005] In actual use, the existing equipment cannot position the raw material in the chuck, which makes the raw material prone to movement during subsequent cutting, thus affecting the cutting quality and reducing production efficiency. In addition, the cutting process easily generates dust, which can spread into the environment and thus have an impact on the environment. Utility Model Content

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] The positioning mechanism includes a fixed plate, the rear end of which is fixedly installed to the top of the output rod of the electric push rod. The fixed plate has symmetrical grooves at all four corners of its surface, and guide grooves are symmetrically installed on the inner walls of both sides of the grooves.

Detailed Implementation

[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] like Figures 1-4 As shown, this utility model provides a positioning and cutting device for chuck production and processing, including a worktable 1.

A limit rod 9 is fixedly installed below the screw 8. A movable seat 10 is slidably sleeved on the outside of the screw 8 and the limit rod 9. A hydraulic cylinder 11 is fixedly connected to the lower end of the movable seat 10. A frame 12 is fixedly connected to the lower end of the output rod of the hydraulic cylinder 11. A motor 13 is fixedly connected to one side of the frame 12. A cutting disc 14 is fixedly sleeved on the outside of the output rod of the motor 13. A motor 2 15 is fixedly connected to the right end of the horizontal plate 7.

[0027] The external screw 8 is threadedly connected to the internal part of the movable seat 10, and the right end of the screw 8 is driven and installed at the output end of the motor 15.

[0028] In this scheme, the electric push rod 4 can push the right fixed plate 51 to move, thereby adjusting the distance between the two fixed plates 51, so that the device can meet the positioning of raw materials of different lengths of chuck. The screw 8 drives the moving seat 10 to move on the limit rod 9, so that the use position of the cutting disc 14 can be adjusted, thereby improving the cutting efficiency.

[0029] like Figure 3 As shown, the dust collection mechanism 2 includes a dust collection box 21. The lower end of the dust collection box 21 is fixedly connected to the inner side of the lower end of the workbench 1. A filter plate 22 is fixedly installed inside the dust collection box 21. A connected dust collection fan 23 is fixedly installed at the right end of the dust collection box 21. A connected dust collection pipe 24 is fixedly installed at the left end of the dust collection box 21. A connected dust collection hood 25 is fixedly installed at the top end of the dust collection pipe 24.

[0030] The upper end of the dust hood 25 is fixedly connected to the lower middle part of the workbench 1, and the dust hood 25 is connected to the hollow groove 6.

[0031] The dust collection box 21 is hinged to the front end with a movable door.

[0032] In this solution, the rotating filter plate 22 can isolate the sucked-in dust, preventing the dust from entering the dust collection fan 23 and causing damage to the fan. The movable door on the dust collection box 21 can be opened to facilitate cleaning of its interior.

[0033] like Figure 4 As shown, the positioning mechanism 5 includes a fixed plate 51. The rear end of the fixed plate 51 is fixedly installed to the top of the output rod of the electric push rod 4. Grooves 52 are symmetrically opened at the four corners of the surface of the fixed plate 51. Guide grooves 53 are symmetrically opened on the inner walls of both sides of the grooves 52. A lead screw 54 is rotatably installed inside the grooves 52. A threaded seat 55 is threaded on the outside of the lead screw 54. Guide blocks 56 are symmetrically fixedly installed on both sides of the threaded seat 55. A clamp 57 is fixedly installed at the front end of the threaded seat 55. Motors 58 are symmetrically fixedly installed at the four corners of the four parts of the fixed plate 51.

[0034] The top of the electric push rod 4 is driven and installed at the output end of the motor 3 58, and the guide block 56 is slidably connected to the guide groove 53.

[0035] The clamp 57 is L-shaped and has an arc-shaped clamping groove on its surface.

[0036] In this solution, four sets of clamps 57 are arranged in a circular pattern to facilitate the positioning and clamping of both ends of the raw material, thereby preventing the raw material from moving during cutting and avoiding affecting the cutting effect.

[0037] The working principle of the positioning and cutting device used in the production and processing of this chuck will be explained in detail below.

[0038] like Figures 1-4As shown, when using the positioning and cutting device for chuck production and processing, the electric push rod 4 can be activated first, which pushes the right-side fixed plate 51, thereby adjusting the distance between the two fixed plates 51. Then, the two ends of the material to be cut can be placed between the clamps 57. Next, the motor 3 58 can be activated, driving the lead screw 54 to rotate, which in turn moves the threaded seat 55, causing the threaded seat 55 to move the guide block 56 synchronously within the guide groove 53. Subsequently, the four clamps 57 gradually approach each other, thus positioning and clamping the two ends of the material. Then, the motor 2 15 can be activated, driving the screw 8 to rotate, thereby... The screw 8 drives the moving seat 10 and the cutting disc 14 to move left and right, thereby adjusting the cutting position of the cutting disc 14. Then, the motor 13 and the hydraulic cylinder 11 can be started. The motor 13 drives the cutting disc 14 to rotate, while the hydraulic cylinder 11 pushes the frame 12 down, so that the cutting disc 14 comes into contact with the raw material, making it easier to cut the raw material. During the cutting process, a large amount of dust will be generated. At this time, the dust extraction fan 23 can be started. With the help of the dust extraction pipe 24, the dust extraction hood 25 and the hollow groove 6, the generated dust can be absorbed and transported to the dust collection box 21 for storage, so as to prevent the dust from spreading into the environment and avoiding the impact on the environment and workers' health.

[0039] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
