Description

Technical Field

[0001] This utility model relates to the field of small parts processing technology, specifically a multi-station rotary fixture for processing small parts. Background Technology

[0002] A fixture is a device used in the mechanical manufacturing process to fix the workpiece in the correct position for machining. Occasionally, irregular or complex parts are encountered in the machining process. The machining of these workpieces requires multiple production processes, among which the clamping process is the most important.

[0003] Existing methods for machining small parts involve using fixtures for fixing. However, due to the large number of small parts, traditional fixtures need to be removed after machining a small part before the next small part can be machined, resulting in low efficiency in machining small parts and failing to meet the needs of mass production of small parts.

[0004] Therefore, a multi-station rotary fixture for machining small parts is proposed. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a multi-station rotary fixture for machining small parts.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-station rotary fixture for machining small parts, comprising a base plate, a rotating shaft rotatably connected to the top of the base plate, a worktable fixedly connected to the top of the rotating shaft, a plurality of clamping assemblies for fixing small parts arranged above the worktable, a plurality of horizontal grooves opened on the top of the worktable, sliders slidably connected to the inner sides of the plurality of horizontal grooves, and locking blocks fixedly connected to the bottom of the plurality of sliders, a frame fixedly connected to the top of the base plate, a lifting assembly arranged inside the frame, a top block arranged above the lifting assembly, and a rotating assembly arranged above the base plate.

[0007] Preferably, each of the clamping components includes two fixed plates, two connecting rods, two springs, a clamping plate, two arc-shaped grooves, and a drive plate. The two fixed plates are fixedly connected to the top of the worktable. The two connecting rods are slidably installed inside one of the fixed plates and extend to both sides. The clamping plate is fixedly connected to one end of the two connecting rods. The drive plate is sleeved and fixedly connected to the outside of the two connecting rods. The two springs are sleeved and installed outside the two connecting rods and fixedly connected to one side of the clamping plate and one side of the fixed plate. The two arc-shaped grooves are located on opposite sides of the clamping plate and the other fixed plate. Through the clamping components, the drive plate drives the connecting rods to move the clamping plate. Combined with the action of the fixed plate in the arc-shaped grooves, the small parts can be clamped and fixed, thus maintaining relative stability during the processing of small parts.

[0008] Preferably, the lifting assembly includes an electric push rod, two vertical rods, and a top plate. The electric push rod is fixedly connected to the inside of the frame, and its output end passes through the frame and is fixedly connected to the top plate. The two vertical rods are fixedly connected to the bottom of the top plate, and their bottom ends slide through and connect to the inside of the frame. Through the lifting assembly, the electric push rod drives the top plate to move, and the movement of the top plate drives the top block to move, which facilitates the driving function of the drive plate when the top block contacts the locking block.

[0009] Preferably, the top block is fixedly connected to the top plate, and the locking block is fixedly connected to the slider.

[0010] Preferably, the rotating assembly includes two mounting plates, a worm gear, a stepper motor, and a worm wheel. The two mounting plates are fixedly connected to the top of the base plate. The stepper motor is fixedly connected to one side of one of the mounting plates. One end of the worm gear is rotatably connected to one side of the other mounting plate. The output end of the stepper motor is fixedly connected to the other end of the worm gear. The worm wheel is sleeved and fixedly connected to the outside of the rotating shaft and meshes with one side of the worm gear. Through the rotating assembly, the stepper motor drives the worm gear to rotate, and the rotation of the worm gear meshes with the worm wheel to rotate, thereby rotating the rotating shaft and achieving the rotation of the worktable.

[0011] Preferably, the top of the base plate is provided with an annular groove, and a plurality of sliding pillars are embedded and slidably connected inside the annular groove. The tops of the plurality of sliding pillars are fixedly connected to the bottom of the worktable. By sliding the sliding pillars inside the annular groove, the worktable can maintain relative stability when it rotates.

[0012] Preferably, a side plate is fixedly connected to the top of the base plate, and a controller for controlling the stepper motor and the electric linear actuator is fixedly installed on the outside of the side plate. The controller facilitates independent control of the stepper motor and the electric linear actuator.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention utilizes a structure comprising a rotating assembly, a lifting assembly, and a clamping assembly. A stepper motor drives a worm gear to rotate and engage a worm wheel, facilitating the rotation of the worktable. Simultaneously, an electric push rod drives a top plate, moving a top block to press against a clamping block. This facilitates the movement of a drive plate, enabling the movement of a connecting rod. The connecting rod then drives the clamping plate to clamp and secure small parts, ensuring stability during the processing of these parts. The simultaneous rotation of the worktable and the movement of the top plate and top block driven by the electric push rod allows for the sequential rotation and clamping of multiple small parts during processing. This avoids the problem of having to process one part and then disassemble and reinstall it during batch processing of small parts, improving work efficiency and meeting the needs of processing large batches of small parts.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] The embodiments of this utility model will be described below based on its overall structure.

[0023] Please see Figure 1 , Figure 2 as well as Figure 5A multi-station rotary fixture for machining small parts includes a base plate 4, a rotating shaft 17 rotatably connected to the top of the base plate 4, and a worktable 1 fixedly connected to the top of the rotating shaft 17. The rotation of the rotating shaft 17 facilitates the rotation of the worktable 1. Several clamping components 2 for fixing small parts are arranged above the worktable 1. Several horizontal grooves 25 are formed on the top of the worktable 1, and sliders 26 are slidably connected to the inner sides of the horizontal grooves 25. Each slider 26 has a locking block 13 fixedly connected to its bottom. The sliding of the sliders 26 within the horizontal grooves 25 facilitates the stable movement of the locking blocks 13. Each clamping component 2 includes two fixed plates 21, two connecting rods 24, two springs 27, a locking plate 23, two arc-shaped grooves 22, and a drive plate 28. The two fixed plates 21 are fixedly connected to the worktable. At the top of platform 1, two connecting rods 24 are slidably installed inside one of the fixed plates 21 and extend to both sides. A clamping plate 23 is fixedly connected to one end of the two connecting rods 24. A drive plate 28 is sleeved and fixedly connected to the outside of the two connecting rods 24. Two springs 27 are sleeved and installed to the outside of the two connecting rods 24 and fixedly connected to one side of the clamping plate 23 and one side of the fixed plate 21. Two arc-shaped grooves 22 are set on the opposite side of the clamping plate 23 and the other fixed plate 21. Through the clamping assembly 2, the drive plate 28 drives the connecting rods 24 to move the clamping plate 23. Combined with the action of the fixed plate 21 in the arc-shaped grooves 22, the small parts can be clamped and fixed, so that the small parts are relatively stable during processing. The top block 14 is fixedly connected to the top plate 15, and the clamping block 13 is fixedly connected to the slider 26.

[0024] Please see Figure 1 and Figure 2 The top of the base plate 4 is provided with an annular groove 7, and several sliding columns 3 are embedded and slidably connected inside the annular groove 7. The top of the sliding columns 3 is fixedly connected to the bottom of the worktable 1. The sliding columns 3 slide inside the annular groove 7 to ensure that the worktable 1 can remain relatively stable when rotating. The top of the base plate 4 is fixedly connected with a side plate 8. A controller 9 for controlling the stepper motor 10 and the electric push rod 12 is fixedly installed on the outside of the side plate 8. The controller 9 facilitates independent control of the stepper motor 10 and the electric push rod 12.

[0025] Please see Figure 4A top block 14 is provided above the lifting assembly, and a rotating assembly is provided above the base plate 4. The rotating assembly includes two mounting plates 5, a worm gear 6, a stepper motor 10, and a worm wheel 18. The two mounting plates 5 are fixedly connected to the top of the base plate 4. The stepper motor 10 is fixedly connected to one side of one of the mounting plates 5. One end of the worm gear 6 is rotatably connected to one side of the other mounting plate 5. The output end of the stepper motor 10 is fixedly connected to the other end of the worm gear 6. The worm wheel 18 is sleeved and fixedly connected to the outside of the rotating shaft 17, and the worm wheel 18 is meshed with one side of the worm gear 6. Through the rotating assembly, the stepper motor 10 drives the worm gear 6 to rotate. The rotation of the worm gear 6 meshes with the worm wheel 18 to rotate, which can rotate the rotating shaft 17 to achieve the rotation of the worktable 1.

[0026] Please see Figure 3 A frame 16 is fixedly connected to the top of the base plate 4. A lifting assembly is installed inside the frame 16. The lifting assembly includes an electric push rod 12, two vertical rods 11, and a top plate 15. The electric push rod 12 is fixedly connected to the inside of the frame 16. The output end of the electric push rod 12 passes through the frame 16 and is fixedly connected to the top plate 15. The two vertical rods 11 are fixedly connected to the bottom of the top plate 15. The bottom ends of the two vertical rods 11 slide through and connect to the inside of the frame 16. Through the lifting assembly, the electric push rod 12 drives the top plate 15 to move. The movement of the top plate 15 drives the top block 14 to move, so that the driving function of the drive plate 28 can be realized when the top block 14 contacts the locking block 13.

[0027] Working principle: In use, multiple small parts are installed between the arc-shaped grooves 22. The stepper motor 10 is controlled by the controller 9, which drives the worm gear 6 to rotate. The rotation of the worm gear 6 drives the worm wheel 18 to rotate, which in turn drives the rotating shaft 17 to rotate. The rotating shaft 17 then drives the worktable 1 to rotate, and simultaneously controls the electric push rod 12. The electric push rod 12 drives the top plate 15 to move, which in turn drives the top block 14 to move. The inclined surface of the top block 14 presses against the inclined surface of the clamping block 13, which drives the slider 26 to slide inside the transverse groove 25. The movement of the slider 26 pushes the drive plate 28 to move, and the movement of the drive plate 28... The connecting rod 24 can be moved, and the external spring 27 of the connecting rod 24 is stretched. After the connecting rod 24 moves, the clamping plate 23 can be moved, so that the small parts between the arc grooves 22 are clamped, which makes it easier to keep the small parts stable during processing. After processing, the top block 14 and the clamping block 13 are separated by the electric push rod 12, and the clamping plate 23 can be moved by the spring 27, which makes it easier to take out the processed small parts. At the same time, the worktable 1 rotates and repeats the above operation under the action of the electric push rod 12. Multiple small parts can be processed, improving the processing efficiency of small parts, which is conducive to the processing of large batches of small parts and is more convenient to use.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
