Description

Technical Field

[0001] This utility model relates to the field of parts processing technology, and in particular to an anti-offset clamping device for processing shaft parts. Background Technology

[0002] Shafts are a common type of hardware component, primarily used to support transmission parts, transmit torque, and bear loads. Based on their structural form, shafts can generally be categorized into three types: plain shafts, stepped shafts, and irregularly shaped shafts; or solid shafts, hollow shafts, etc. In industrial products, shafts are used in the maintenance and operation of parts processed by one or more CNC machine tools. They support transmission parts such as gears and pulleys in machines to transmit torque or motion. During processing, the columnar structure of shafts leads to different requirements for clamping devices corresponding to shafts of different diameters, currently presenting operational inconveniences when clamping shafts of different diameters.

[0003] For example, a clamping device for machining shaft parts disclosed in Chinese patent literature (publication number: CN222037593U) forms a hexagonal clamping structure by fitting multiple sets of clamping components together. In addition, the rubber anti-slip pads on the sides of the clamping components can fully clamp the shaft parts. The presence of the control slider can make the six clamping components operate synchronously to open and close. Because the opening and closing movement allows the device to handle shaft parts of different diameters.

[0004] However, when fixing shaft-type parts, the operator needs to hold the clamping rotary table with one hand to rotate it, driving the six clamping components to close and fit against the shaft surface simultaneously. After the clamping components are in place, the operator needs to maintain a stable gripping posture while using the other hand to turn the knob to lock the clamping rotary table. When operating with both hands, it is easy for the force to become unbalanced, causing the clamping rotary table to slightly retract, creating a gap between the clamping components and the shaft-type parts, resulting in loose clamping and causing deviation problems in subsequent processing. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies. Currently, when fixing shaft-type parts, the coordinated operation of both hands can easily lead to an imbalance of force, causing the clamps to loosen and resulting in deviations during subsequent processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An anti-offset clamping device for machining shaft parts includes a fixed base, and a clamping mechanism is provided above the fixed base; The clamping mechanism includes a circular mounting block, the lower end of which is fixedly connected to the upper end of the fixed base. The upper end of the circular mounting block has a placement groove. The outside of the circular mounting block is rotatably connected to a drive cover via a bearing. The upper end of the drive cover has a through hole and a drive groove arranged in a ring array. A self-locking mechanism is provided above the fixed base.

[0007] Preferably, the upper end of the circular mounting block is provided with a hexagonal groove, and the inner wall of the hexagonal groove is slidably connected to a guide slider distributed in a ring array, and the upper end of the guide slider is fixedly connected to a triangular clamping plate.

[0008] Preferably, the lower ends of the plurality of triangular clamping plates are in contact with the upper end of the circular mounting block, and V-shaped anti-slip pads are provided on both sides of the inclined surfaces of the triangular clamping plates.

[0009] Preferably, two adjacent V-shaped anti-slip pads are in contact with each other, and a slide rod is fixedly connected to the upper end of the triangular clamping plate. The outside of the slide rod is slidably connected to the inner wall of the drive groove.

[0010] Preferably, the drive self-locking mechanism includes a first rotating rod, the lower end of which is rotatably connected to the upper end of the fixed base via a bearing, and a rotating block is fixedly connected to the upper end of the first rotating rod.

[0011] Preferably, the inner wall of the rotating block is rotatably connected to a screw via a bearing, one end of the screw is fixedly connected to a drive handwheel, and the external thread of the screw is connected to a threaded block.

[0012] Preferably, a second rotating rod is fixedly connected to the lower end of the threaded block, and a fixed plate is rotatably connected to the lower end of the second rotating rod via a bearing. One end of the fixed plate is fixedly connected to the outside of the drive cover.

[0013] Compared with the prior art, the beneficial effects of this utility model are: In this invention, multiple triangular clamping plates move synchronously along a hexagonal groove in the clamping mechanism. Combined with a V-shaped anti-slip pad, it can accommodate shaft parts of different diameters, automatically centering and preventing clamping deviation. Furthermore, the screw drive and adaptive rotation design of the self-locking mechanism allow the operator to complete clamping and locking simply by turning the drive handwheel, eliminating the need for manual maintenance. This solves the problems of difficult operation and unstable clamping in traditional devices. Simultaneously, the device has a compact structure, stable transmission, and uniform force on the shaft parts during clamping. The anti-slip pad enhances friction, effectively preventing slippage during processing, significantly improving the accuracy and efficiency of shaft part processing, and reducing operational difficulty.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: an anti-deviation clamping device for machining shaft parts, including a fixed base 1, which serves as the basic load-bearing structure of the device. It is made of high-strength metal material, has good rigidity and stability, can effectively disperse vibration loads during machining, and provides a stable installation platform for the clamping mechanism and the self-locking drive mechanism, ensuring the overall stability of shaft parts during machining.

[0021] A clamping mechanism is provided above the fixed base 1 to achieve centered clamping and anti-offset fixation of shaft parts. The clamping mechanism includes a circular mounting block 2. The lower end of the circular mounting block 2 is fixedly connected to the upper end of the fixed base 1. The connection part adopts welding process to improve structural strength. The upper end of the circular mounting block 2 is provided with a placement groove 21 for preliminary positioning of the lower end of the shaft parts.

[0022] The drive cover 22 is rotatably connected to the outside of the circular mounting block 2 via a bearing. The bearing is a high-precision sealed bearing, which reduces rotational friction and prevents dust from entering, ensuring the smooth rotation of the drive cover 22. The upper end of the drive cover 22 has a through hole 23 for shaft parts to pass through. The upper end of the drive cover 22 has a drive groove 24 arranged in a ring array to provide movement guidance for the slide rod 29.

[0023] The upper end of the circular mounting block 2 is provided with a hexagonal groove 25, which provides a precise movement trajectory for the guide slider 26. The inner wall of the hexagonal groove 25 is slidably connected to the guide sliders 26 arranged in a ring array. The cooperation between the guide sliders 26 and the hexagonal groove 25 can limit the movement direction of the triangular clamping plate 27, ensuring that it converges or separates towards the center synchronously and stably. The upper end of the guide slider 26 is fixedly connected to the triangular clamping plate 27. Multiple triangular clamping plates 27 are arranged in a ring, which together form a ring-shaped clamping structure for shaft parts.

[0024] The lower ends of multiple triangular clamping plates 27 are in contact with the upper end of the circular mounting block 2 to ensure stability during clamping. V-shaped anti-slip pads 28 are provided on both sides of the triangular clamping plates 27. The V-shaped structure can be adapted to shaft parts of different diameters to achieve automatic centering and avoid clamping offset. The anti-slip pads are made of rubber with a high coefficient of friction, which can effectively increase the friction with the surface of shaft parts and prevent the parts from slipping during processing.

[0025] The two adjacent V-shaped anti-slip pads 28 are in contact with each other, further enhancing the sealing and stability of the clamping. The upper end of the triangular clamping plate 27 is fixedly connected to the slide rod 29. The outside of the slide rod 29 is slidably connected to the inner wall of the drive groove 24. The rotation of the drive cover 22 can drive the slide rod 29 to move through the drive groove 24, thereby causing the triangular clamping plate 27 to move along the hexagonal slide groove 25.

[0026] A drive self-locking mechanism is provided above the fixed base 1 to provide power to the clamping mechanism and realize the self-locking function. The drive self-locking mechanism includes a first rotating rod 3. The lower end of the first rotating rod 3 is rotatably connected to the upper end of the fixed base 1 through a bearing to ensure smooth rotation. A rotating block 31 is fixedly connected to the upper end of the first rotating rod 3. The rotating block 31 can rotate adaptively with the first rotating rod 3. It works with the threaded block 34 and the second rotating rod 35 to realize stable power transmission.

[0027] The inner wall of the rotating block 31 is rotatably connected to the screw 32 via a bearing. The bearing reduces friction when the screw 32 rotates. One end of the screw 32 is fixedly connected to a drive handwheel 33. The surface of the drive handwheel 33 is provided with anti-slip texture to facilitate rotation by the operator. The screw 32 is externally threaded to a threaded block 34. The rotation of the screw 32 can cause the threaded block 34 to move along its axial direction through thread transmission.

[0028] The lower end of the threaded block 34 is fixedly connected to a second rotating rod 35. The lower end of the second rotating rod 35 is rotatably connected to a fixed plate 36 via a bearing. One end of the fixed plate 36 is fixedly connected to the outside of the drive cover 22. The movement of the threaded block 34 can drive the drive cover 22 to rotate through the second rotating rod 35 and the fixed plate 36.

[0029] The working process of this utility model: Step 1: Pass the lower end of the shaft part to be processed through the through hole 23 of the drive cover 22 and place it stably in the placement groove 21 of the circular mounting block 2 to ensure the initial positioning of the part. Rotate the drive handwheel 33 to drive the screw 32 to rotate. The screw 32 causes the threaded block 34 to move along its axial direction through the threaded transmission. When the threaded block 34 moves, it drives the drive cover 22 to rotate around the circular mounting block 2 through the second rotating rod 35 and the fixing plate 36. During this process, the rotating block 31 rotates adaptively through the first rotating rod 3, and cooperates with the rotational connection between the second rotating rod 35 and the threaded block 34 to achieve adaptive rotational cooperation between the threaded block 34 and the rotating block 31, ensuring the stable rotation of the drive cover 22. When the drive cover 22 rotates, its drive groove 24 drives the slide rod 29 to move. The slide rod 29 causes multiple triangular clamping plates 27 to move synchronously along the hexagonal slide groove 25 through the guide slider 26. The V-shaped anti-slip pads 28 of the multiple triangular clamping plates 27 gradually adhere to the surface of the shaft part, clamping the part in the center until the part is stably fixed. Step two: After clamping is complete, stop rotating the drive handwheel 33. The thread self-locking characteristic of the screw 32 keeps the clamping state stable. At this time, the processing equipment can be started to process the shaft parts. During the processing, the V-shaped anti-slip pad 28 increases the friction, and the synchronous movement design of the triangular clamping plate 27 ensures that the parts are subjected to uniform force, effectively preventing deviation and slippage, and ensuring processing accuracy. After processing is completed, rotate the drive handwheel 33 in the opposite direction, causing the screw 32 to rotate in the opposite direction and the threaded block 34 to move in the opposite direction. Through the fixed plate 36 and the drive cover 22, the slide bar 29 moves in the opposite direction, causing the triangular clamping plate 27 to move in the opposite direction along the hexagonal slide groove 25, disengaging from the clamping of the shaft parts. At this time, the processed parts can be taken out from the placement groove 21.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
