Description

Technical Field

[0001] This utility model relates to the field of fastener processing technology, and in particular to a fastener processing positioning device. Background Technology

[0002] Bolts, as one of the most basic and widely used fasteners, require frequent, precise, and reliable clamping and positioning during their processing, such as head forming, thread rolling, slot milling, and chamfering. The performance of the positioning device directly affects the dimensional accuracy, thread quality, and processing efficiency of the bolts. This is especially true in flexible production lines with multiple varieties and small batches, where higher demands are placed on the versatility, rapid changeover, and clamping stability of the positioning device.

[0003] Currently, the commonly used positioning devices for bolt processing are general-purpose flat-jaw vises or special-purpose clamps. General-purpose flat-jaw vises achieve clamping by rotating a screw to drive the moving jaws. Although special-purpose clamps are designed for specific bolt types and provide precise positioning, they lack versatility. When changing products, the entire clamp needs to be replaced, resulting in low equipment utilization and an inability to meet the production needs of rapid switching between multiple product types.

[0004] Therefore, existing positioning devices of this type have the following drawbacks: poor adaptability, cumbersome changeover, and a single fixture often only accommodates bolt heads of a single specification or shape. When the workpiece is changed from a hexagonal head bolt to a flange bolt or other irregular head bolt, the machine must be stopped and the entire clamping module replaced, resulting in long changeover times and severely restricting the overall rhythm and flexibility of the production line. Therefore, there is an urgent need for a universal positioning device that can provide stable and reliable clamping force and has rapid changeover capabilities to adapt to the processing of various bolts. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fastener processing positioning device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fastener processing positioning device, including a base and multiple sets of clamping components. Each set of clamping components includes two clamping plates, and the clamping plates of each set of clamping components have different shapes and sizes. A side plate is fixed on one side of the upper surface of the base. A first wedge block is provided on the side of the upper surface of the base opposite to the side plate, and a T-shaped slider is fixed on the lower surface of the first wedge block. A T-shaped groove is provided on the upper surface of the base, and the T-shaped slider is slidably connected to the T-shaped groove. A threaded groove is provided on the side of the upper surface of the base near the first wedge block, and a pressing component for pushing the first wedge block to move is threadedly connected inside the threaded groove.

[0007] Furthermore, the surface of the clamping plate is fixed with a plug rod, and slots for inserting the plug rod are provided on the adjacent sides of the side plate and the first wedge block.

[0008] Furthermore, a magnet is fixed to the inner wall of the slot, and the insertion rod is made of iron.

[0009] Furthermore, the T-shaped slider and the inner wall of the T-shaped groove are both fixedly connected with a spring.

[0010] Furthermore, the extrusion assembly includes a second wedge block and a screw threaded into the threaded groove. The second wedge block has a through hole in the middle for the screw to pass through, and the second wedge block is slidably connected to the through hole. An end cap is fixed to the top of the screw, and a handle is fixed to the side wall of the end cap. The inclined surface of the second wedge block is in contact with the inclined surface of the first wedge block.

[0011] Furthermore, a guide rod is fixed to the lower surface of the second wedge block, and a guide groove is provided on the upper surface of the base. The guide rod is located inside the guide groove and is slidably connected to the guide groove.

[0012] Furthermore, mounting plates are fixed on both sides of the bottom end of the base, and mounting holes are provided on the mounting plates.

[0013] The beneficial effects of this utility model are:

[0014] This invention improves the stability and flexibility of clamping by optimizing the clamping and locking structure. It employs a wedge block transmission mechanism, where the compression component drives the first wedge block in linear motion, efficiently converting this motion into synchronous, powerful radial clamping of the workpiece by the two clamping components. This compact design facilitates integration into various machine tools. Furthermore, the clamping plates of the clamping components feature a modular design, allowing for quick replacement of specialized clamping plates for bolts with different head shapes, such as hexagonal or flanged bolts, without requiring adjustments to the main structure. This significantly improves the device's adaptability to different specifications and types of fasteners while maintaining clamping rigidity, thus shortening changeover time.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4 As shown, a fastener processing positioning device is disclosed, including a base 1 and multiple sets of clamping components 4. Each set of clamping components 4 includes two clamping plates 41, and the clamping plates 41 of each set of clamping components 4 have different shapes and sizes. A side plate 2 is fixed on one side of the upper surface of the base 1. A first wedge block 3 is provided on the side of the upper surface of the base 1 opposite to the side plate 2, and a T-shaped slider 31 is fixed on the lower surface of the first wedge block 3. A T-shaped groove 101 is provided on the upper surface of the base 1, and the T-shaped slider 31 is slidably connected to the T-shaped groove 101. A threaded groove 102 is provided on the side of the upper surface of the base 1 near the first wedge block 3, and a pressing component 7 for pushing the first wedge block 3 to move is threadedly connected inside the threaded groove 102.

[0024] Mounting plates 8 are fixed to both sides of the bottom end of the base 1, and mounting holes are provided on the mounting plates 8. The mounting plates 8 can be installed and fixed to the installation position of the bolt processing equipment through the mounting holes.

[0025] The surface of the clamping plate 41 is fixed with a plug rod 42, and slots 5 for inserting the plug rod 42 are provided on the adjacent sides of the side plate 2 and the first wedge block 3.

[0026] When installing each clamping assembly 4, insert the pins 42 on the surfaces of the two clamping plates 41 of the clamping assembly 4 into the slots 5 on the surfaces of the side plate 2 and the first wedge block 3, respectively. Both the slots 5 and the pins 42 are square for easy positioning.

[0027] A magnet 6 is fixed to the inner wall of slot 5, and the insertion rod 42 is made of iron.

[0028] After the insertion rod 42 is inserted into the slot 5, it is fixed by the attraction of the magnet 6, making the installation and disassembly of the clamping component 4 simpler and more convenient.

[0029] The T-shaped slider 31 and the inner wall of the T-shaped groove 101 are both fixedly connected to a spring 32.

[0030] The spring 32 is located near the side plate 2. When the first wedge block 3 moves to the side plate 2, it drives the T-shaped slider 31 to move along the T-shaped groove 101, thereby squeezing the spring 32. When the first wedge block 3 is not squeezed by the squeezing component 7, the spring 32 rebounds and drives the first wedge block 3 to reset. The sliding of the T-shaped slider 31 along the T-shaped groove 101 can also prevent the first wedge block 3 from separating from the upper surface of the base 1.

[0031] The extrusion assembly 7 includes a second wedge block 72 and a screw 71 threadedly connected to the inside of the threaded groove 102. The second wedge block 72 has a through hole in the middle for the screw 71 to pass through, and the second wedge block 72 is slidably connected to the through hole. An end cap 73 is fixed to the top of the screw 71, and a handle 74 is fixed to the side wall of the end cap 73. The inclined surface of the second wedge block 72 is in contact with the inclined surface of the first wedge block 3.

[0032] Rotating the screw 71 via the handle 74 causes the screw 71 to move along the threaded groove 102. When the screw 71 moves downward, the end cap 73 presses down on the second wedge block 72. The inclined surface of the second wedge block 72 then presses against the inclined surface of the first wedge block 3, causing the first wedge block 3 to move toward the side plate 2. This causes the clamping assembly 4 on the first wedge block 3 to move, thereby using the two clamping assemblies 4 to press and fix the fastener in the middle. When the screw 71 is rotated upward, the second wedge block 72 no longer presses against the first wedge block 3, and the spring 32 pushes the first wedge block 3 to reset. The inclined surface of the first wedge block 3 also pushes the second wedge block 72 upward.

[0033] The second wedge block 72 has a guide rod 75 fixed on its lower surface, and the base 1 has a guide groove 103 on its upper surface. The guide rod 75 is located inside the guide groove 103 and is slidably connected to the guide groove 103.

[0034] The guide rod 75 can only slide up and down along the guide groove 103, thereby guiding the up and down movement of the second wedge block 72.

[0035] Working principle: First, select a set of clamping components 4 that match the head shape of the bolt to be processed, such as a hexagonal head or flange face. Insert the insert rods 42 on the back of the two clamping plates 41 into the slots 5 of the side plate 2 and the first wedge block 3, respectively, and fix them by the magnets 6 in the slots, completing the quick change-up installation. Then, place the bolt to be processed between the two installed clamping plates 41.

[0036] Next, the clamping operation is performed: the operator rotates the screw 71 of the compression assembly 7 clockwise via handle 74, causing it to screw downwards along the threaded groove 102 of the base 1. As the screw 71 moves downwards, the end cap 73 at its tip presses down against the second wedge block 72, forcing the second wedge block 72 to move vertically downwards along the path defined by the guide rod 75 and the guide groove 103. The inclined surface of the second wedge block 72 contacts the inclined surface of the first wedge block 3 and generates an interaction force, converting the vertical downward pressure into a horizontal thrust, driving the first wedge block 3 to overcome the elastic force of the spring 32 and slide along the T-shaped slide groove 101 on the base 1 towards the fixed side plate 2.

[0037] As the first wedge block 3 moves, the clamping plate 41 installed on it moves towards the side plate 2 in sync, and works in conjunction with another clamping plate 41 fixed on the side plate 2 to stably and forcefully clamp the bolt in the middle from both sides, thus completing the positioning and locking.

[0038] After processing, rotating handle 74 counterclockwise causes screw 71 to rise, releasing pressure on the second wedge block 72. At this time, the compressed spring 32 releases its elastic force, pushing the first wedge block 3 to slide back along the T-shaped groove 101. Simultaneously, the inclined surface of the first wedge block 3 pushes the second wedge block 72 upwards to return to its original position. The clamping force is then released, and the processed bolt can be removed. The entire process achieves efficient and stable clamping and rapid release through the wedge-shaped force-increasing mechanism.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
