Description

Technical Field

[0001] This utility model relates to the field of bushing processing technology, specifically a punching device for bushing production. Background Technology

[0002] A bushing is a mechanical part whose main functions in mechanical devices include reducing friction and wear, providing support and positioning, sealing, and damping vibration and noise. Therefore, it is widely used in various mechanical equipment.

[0003] A search revealed a Chinese patent with publication number CN210999080U, which discloses a punching device for bushing production. The key technical feature of this invention is that it is equipped with a first slide, a first slider, a third slide, a third slider and a first motor, as well as a second slide, a second slider, a fourth slide, a fourth slider and a second motor. This allows for simultaneous punching of bushings by two punching mechanisms, effectively improving the punching efficiency of the device and solving the problem of low punching efficiency in existing punching devices that only have a single punching mechanism.

[0004] However, in the prior art, after the parts are processed, they need to be unfixed and disassembled, and then replaced with new parts, and then fixed and adjusted again, which increases the working time. In order to solve the problem of low work efficiency in the prior art, this application proposes to fix the pre-processed parts while the parts are being processed, so that the parts can be directly replaced after the parts are processed, thereby improving the work efficiency. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0005] In view of the shortcomings and defects of the existing technology mentioned above, which are characterized by low working efficiency, this paper addresses these issues.

[0006] The present invention discloses a punching device for bushing production, comprising a workbench, a rotating plate being provided on the workbench, the rotating plate being rotatably mounted on the workbench via a rotating shaft, a reciprocating assembly being provided between the rotating plate and the workbench, limit cylinders being provided at both ends of the rotating plate, clamping assemblies being provided on the limit cylinders, and a fixing frame being provided at one end of the workbench, with fixing assemblies being provided on the fixing frame.

[0007] Furthermore, the reciprocating assembly includes a gear and a rack. The gear is mounted on the rotating shaft and meshes with the rack for transmission. The rack is slidably disposed with respect to the worktable, and an electric telescopic rod is provided between the rack and the worktable.

[0008] Furthermore, the clamping assembly includes an arc-shaped plate disposed on the limiting cylinder, a sleeve is installed on one side of the limiting cylinder, a U-shaped plate is installed on the outer side of the limiting cylinder, and a screw is rotatably installed on the U-shaped plate, the screw being threadedly connected to the sleeve.

[0009] Furthermore, guide plates are provided at both ends of the arc-shaped plate, and the guide plates are slidably disposed with the U-shaped plate.

[0010] Furthermore, the fixing component includes a pressure block, which is disposed between the worktable and the fixing frame, and a telescopic cylinder is disposed between the pressure block and the fixing frame.

[0011] Furthermore, a protective plate is provided on one side of the fixing frame, and the protective plate is connected to the fixing frame by fixing bolts. The protective plate is made of transparent glass in the middle.

[0012] Furthermore, a stepped ring is installed on the workbench, and the stepped ring is rotatably connected to the rotating plate.

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

[0014] 1. This utility model is equipped with components such as a rotating plate, a limiting cylinder, a screw, and an arc-shaped plate. During operation, the limiting cylinder, screw, and arc-shaped plate components work together. By adjusting the rotation of the screw, the screw pushes the arc-shaped plate to move, thereby clamping and fixing the parts placed inside the limiting cylinder. The reciprocating assembly drives the rotating shaft to rotate the rotating plate, thereby exchanging the positions of the two limiting cylinders and the fixed parts inside, thus achieving continuous operation and improving work efficiency.

[0015] 2. This utility model, by incorporating components such as a fixed frame, a telescopic cylinder, a pressure block, and a protective plate, allows the pressure block to move towards the part and press it firmly during operation once the part reaches the processing position. The telescopic cylinder, fixed frame, and pressure block work together to improve stability during processing. Furthermore, the protective plate shields the processing area, preventing debris from flying and injuring workers, thus enhancing the safety of the device. Attached Figure Description

[0022] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0023] Please see Figure 1 , Figure 2 The present invention discloses a punching device for bushing production, comprising a workbench 1, which is mounted on a base 18 by fixing bolts. A drill is provided at one end of the base 18, and a controller is provided at the other end of the base 18. A rotating plate 2 is provided on the workbench 1, which is rotatably mounted on the workbench 1 by a rotating shaft 4. A reciprocating assembly is provided between the rotating plate 2 and the workbench 1. Limiting cylinders 3 are provided at both ends of the rotating plate 2, and clamping assemblies are provided on the limiting cylinders 3. A fixing frame 8 is provided at one end of the workbench 1, and a fixing assembly is provided on the fixing frame 8.

[0024] See Figure 3 As shown, the reciprocating assembly includes a gear 5 and a rack 6. The gear 5 is mounted on the rotating shaft 4, and the gear 5 meshes with the rack 6 for transmission. The rack 6 is slidably disposed with respect to the worktable 1. An electric telescopic rod 7 is disposed between the rack 6 and the worktable 1. Positioning blocks 16 are disposed on both the two limiting cylinders 3 and the worktable 1. When the rotating plate 2 rotates, it drives the positioning blocks 16 to rotate as well. When the positioning block 16 on the limiting cylinder 3 contacts the positioning block 16 on the worktable 1, the electric telescopic rod 7 stops working, realizing the position exchange of the two limiting cylinders 3. When the position needs to be exchanged again, the electric telescopic rod 7 can be operated in the reverse direction.

[0025] like Figure 4As shown, the clamping assembly includes an arc-shaped plate 11. There are two arc-shaped plates 11, which are set on the limiting cylinder 3. The two arc-shaped plates 11 are symmetrically arranged. A sleeve 14 is installed on one side of the limiting cylinder 3. A U-shaped plate 12 is installed on the outside of the limiting cylinder 3. A screw 13 is rotatably installed on the U-shaped plate 12. The screw 13 is threadedly connected to the sleeve 14.

[0026] In this embodiment, guide plates 15 are provided at both ends of the arc plate 11. The guide plates 15 are slidably disposed with the U-shaped plate 12. The operator drives the screw 13 to rotate, and the screw 13 pushes the arc plate 11 to move through the sleeve 14. While the arc plate 11 moves, it drives the guide plates 15 to slide on the U-shaped plate 12, thereby preventing the arc plate 11 from rotating and guiding the movement direction of the arc plate 11. At the same time, it increases the contact area between the arc plate 11 and the limiting cylinder 3, thereby increasing the stability during the working process.

[0027] Looking back Figure 2 As shown, the fixing component includes a pressure block 9, which is disposed between the worktable 1 and the fixing frame 8. A telescopic cylinder 10 is disposed between the pressure block 9 and the fixing frame 8. The telescopic cylinder 10 is controlled by a controller to work. When the telescopic cylinder 10 drives the pressure block 9 to move downward and presses the part, it fixes the part. When the telescopic cylinder 10 is driven in the opposite direction, it drives the pressure block 9 to move upward, thereby releasing the fixation of the part.

[0028] like Figure 1 As shown, a protective plate 19 is provided on one side of the fixed frame 8. The protective plate 19 is connected to the fixed frame 8 by fixing bolts. The protective plate 19 is made of transparent glass in the middle. The protective plate 19 blocks the debris during processing, thereby avoiding injury to the workers.

[0029] In this embodiment, a stepped ring 17 is installed on the workbench 1. The stepped ring 17 is rotatably connected to the rotating plate 2. The stepped ring 17 increases the contact area between the rotating plate 2 and the workbench 1, thereby improving the stability of the rotating plate 2 during operation.

[0030] The implementation principle is as follows: First, one end of the part to be processed is placed into the limiting cylinder 3. Then, the operator drives the screw 13 to rotate, and the arc plate 11 moves through the sleeve 14 to clamp and fix the part. Then, the electric telescopic rod 7 is controlled to work, and the electric telescopic rod 7 drives the rack 6 to move. The rack 6 drives the meshing gear 5 to rotate, and the gear 5 drives the rotating shaft 4 to rotate. The rotating shaft 4 drives the rotating plate 2 to rotate, so that the positions of the two limiting cylinders 3 are swapped. Then, the telescopic cylinder 10 is controlled to drive the pressure block 9 to move downward and press and fix the part. Then, the drilling machine on the base 18 is controlled to process the part. While processing, the operator puts the pre-processed part into the corresponding limiting cylinder 3. After the part is processed, it can be directly replaced, thereby improving work efficiency.

[0031] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
