Description

Technical Field

[0001] This utility model relates to the field of crusher blade technology, specifically a clamping fixture for crusher blade processing. Background Technology

[0002] Crusher blades are specialized cutting tools installed on plastic processing machinery, primarily used for material crushing in injection molding, plastic recycling, and granulation. Their core function is to break plastic materials into uniform particles through the shearing action of moving and stationary blades, with adjustable particle size to meet different process requirements. During the machining of crusher blades, clamping fixtures are typically used to hold them in place to ensure machining accuracy and improve machining stability. Clamping fixtures (also called jigs or positioning fixtures) are devices used to fix, position, and support workpieces during machining. Their main function is to ensure the workpiece maintains the correct position and orientation during machining, preventing displacement due to vibration or cutting forces, thereby ensuring machining accuracy and operational safety. Clamping fixtures effectively clamp the blades, improving machining stability and preventing the blades from loosening or flying off during machining, protecting operators and equipment safety.

[0003] In the prior art, when clamping crusher blades, although the clamping fixture can clamp and fix the blades well, the blades cannot be positioned well during the clamping process, which may cause the clamped blades to be skewed. This makes it difficult to ensure the uniformity of the clamping force and is not conducive to improving the clamping effect and quality. Therefore, in order to solve the above problems, a clamping fixture for crusher blade processing is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping fixture for processing crusher blades, so as to solve the problem mentioned in the background art that the blades may be skewed after clamping due to the inability to properly position the blades during the clamping process, which makes it difficult to ensure the uniformity of the clamping force and is not conducive to improving the clamping effect and quality.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a clamping fixture for processing crusher blades, comprising a base, a support block fixedly connected to the upper surface of the base, and a connecting frame provided on the surface of the support block, a first telescopic cylinder fixedly installed on the inner side of the connecting frame, and a clamping plate fixedly connected to the output end of the first telescopic cylinder, and a support platform provided on the top of the base; The base is provided with a positioning mechanism on its surface, and the support block is provided with an auxiliary mechanism on its inner side. The positioning mechanism includes a connecting block, which is movably disposed inside the base, and a limiting block is fixedly connected to the top of the connecting block. The limiting blocks are arranged in two sets and located on both sides of the support platform. The auxiliary mechanism includes a rotating rod, which is movably connected to the inner side of the support block, and a second motor is fixedly installed on the surface of the support block. The output ends of the rotating rod and the second motor are fixedly connected.

[0006] Preferably, the positioning mechanism further includes a fixing block, which is fixedly connected to the lower surface of the base, and a positive and negative screw is movably connected to the inner side of the fixing block. A first motor is fixedly installed on the surface of the fixing block, and the positive and negative screw is fixedly connected to the output end of the first motor.

[0007] Preferably, the surfaces of the positive and negative screws are threaded with movable blocks, and the movable blocks are in two sets and movably connected to the positive and negative screws. The connecting blocks are in two sets and correspondingly arranged with the movable blocks and fixedly connected to the movable blocks.

[0008] Preferably, a first limiting rod is fixedly connected to the inner surface of the fixed block, and the moving block and the first limiting rod are movably connected. The inner side of the base is provided with a movable groove, and the connecting block is movable inside the movable groove.

[0009] Preferably, the auxiliary mechanism further includes a connecting ring, which is fixedly connected to the surface of the connecting frame, and a rotating groove is provided on the inner side of the support block. Both the connecting ring and the rotating groove are annular, and the end of the connecting ring away from the connecting frame moves within the rotating groove.

[0010] Preferably, the end of the rotating rod away from the second motor is fixedly connected to the connecting frame, and the second telescopic cylinder is fixedly installed on the inner side of the base, and the support platform and the output of the second telescopic cylinder are fixedly connected.

[0011] Preferably, a second limiting rod is fixedly connected to the lower surface of the support platform, and the second limiting rod is arranged in two sets and movably connected to the base.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. By rotating the forward and reverse screws, the moving block can drive the connecting block to move, and the limiting block can move accordingly to push and limit the blade on the support table, thereby achieving the effect of positioning the blade. When the connecting frame and clamping plate clamp the blade, the edge of the blade on the support table is consistent and it is not easy to be skewed, which helps to improve the clamping effect of the blade and facilitates better processing of the blade.

[0013] 2. The rotation of the connecting frame is achieved by the rotation of the rotating rod driven by the second motor, which facilitates the flipping of the blade inside the connecting frame, thus making it easier to process both sides of the blade. At the same time, the extension and retraction of the second telescopic cylinder can drive the support platform to rise and fall. The lowering of the support platform can prevent it from affecting the blade during flipping, and the raising of the support platform can match the height of the connecting frame, thus ensuring support for the blade.

[0016] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5 One embodiment provided by this utility model: The first telescopic cylinder 13, the first motor 22, the second motor 31, and the second telescopic cylinder 34 used in this application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0018] A clamping fixture for processing crusher blades includes a base 1, a support block 11 fixedly connected to the upper surface of the base 1, a connecting frame 12 provided on the surface of the support block 11, a first telescopic cylinder 13 fixedly installed on the inner side of the connecting frame 12, and a clamping plate 14 fixedly connected to the output end of the first telescopic cylinder 13. A support platform 15 is provided on the top of the base 1. A positioning mechanism is provided on the surface of the base 1, and an auxiliary mechanism is provided on the inner side of the support block 11. The positioning mechanism includes a connecting block 24, which is movably disposed on the inner side of the base 1, and a limit block 25 is fixedly connected to the top of the connecting block 24. The limiting blocks 25 are arranged in two groups on both sides of the support platform 15. The auxiliary mechanism includes a rotating rod 3, which is movably connected to the inner side of the support block 11. A second motor 31 is fixedly installed on the surface of the support block 11. The output ends of the rotating rod 3 and the second motor 31 are fixedly connected. The blade can be supported by the support platform 15. By placing the blade on the support platform 15, the end of the blade enters the connecting frame 12 and rests on the surface of the connecting frame 12. The blade can be clamped by extending the first telescopic cylinder 13 and driving the clamping plate 14 to descend, thereby enabling the blade to be processed.

[0019] Furthermore, the positioning mechanism also includes a fixing block 2, which is fixedly connected to the lower surface of the base 1. A positive and negative screw 21 is movably connected to the inner side of the fixing block 2. A first motor 22 is fixedly installed on the surface of the fixing block 2, and the output end of the positive and negative screw 21 and the first motor 22 are fixedly connected. By rotating the positive and negative screw 21, the moving block 23 can drive the connecting block 24 to move, and the limiting block 25 can move accordingly to achieve the positioning of the blade. This ensures the stability of the blade on the support platform 15 and the clamping plate 14 when clamping the blade, making it less likely for the blade to be tilted.

[0020] Furthermore, the surfaces of the positive and negative screws 21 are threaded with movable blocks 23, and the movable blocks 23 are movably connected to the positive and negative screws 21 in two sets. The connecting blocks 24 are arranged in two sets corresponding to the movable blocks 23 and are fixedly connected to the movable blocks 23. By setting the connecting blocks 24, the movable blocks 23 can move, and the connecting blocks 24 can drive the limiting blocks 25 to move accordingly. Then the limiting blocks 25 move and contact the two ends of the blade, which can limit the blade and make it easier to clamp the blade.

[0021] Furthermore, a first limiting rod 26 is fixedly connected to the inner surface of the fixed block 2, and the moving block 23 is movably connected to the first limiting rod 26. An movable groove 27 is opened on the inner side of the base 1, and the connecting block 24 is movable inside the movable groove 27. By setting the first limiting rod 26 and opening the movable groove 27, the moving block 23 and the connecting block 24 can be limited, which can prevent the moving block 23 and the connecting block 24 from shifting under the action of the positive and negative screws 21, and facilitate the moving block 23 to drive the connecting block 24 and the limiting block 25 to move stably.

[0022] Furthermore, the auxiliary mechanism also includes a connecting ring 32, which is fixedly connected to the surface of the connecting frame 12. A rotating groove 33 is provided on the inner side of the support block 11. Both the connecting ring 32 and the rotating groove 33 are annular, and the end of the connecting ring 32 away from the connecting frame 12 moves within the rotating groove 33. By setting the connecting ring 32 and opening the rotating groove 33, the stable rotation of the connecting frame 12 can be ensured, thereby ensuring the stable flipping of the blade.

[0023] Furthermore, the end of the rotating rod 3 away from the second motor 31 is fixedly connected to the connecting frame 12. The second telescopic cylinder 34 is fixedly installed on the inner side of the base 1, and the support platform 15 is fixedly connected to the output of the second telescopic cylinder 34. The rotating rod 3 is driven to rotate by the operation of the second motor 31, so that the connecting frame 12 can rotate under the action of the rotating rod 3, which makes it easier to flip the blade and thus facilitate the processing of both sides of the blade.

[0024] Furthermore, a second limiting rod 35 is fixedly connected to the lower surface of the support platform 15, and the second limiting rod 35 is arranged in two sets and movably connected to the base 1. The setting of the second limiting rod 35 can limit the support platform 15, which can ensure that the support platform 15 can move vertically stably under the action of the second telescopic cylinder 34, thereby ensuring the stability of the blade support.

[0025] Working principle: In use, the first motor 22 is electrically connected to an external power source. The operator starts the first motor 22 by pressing the switch. The first motor 22 drives the positive and negative screws 21 to rotate. The moving block 23 is limited by the first limiting rod 26 and moves under the action of the positive and negative screws 21, and moves on the surface of the first limiting rod 26. Then, the connecting block 24 moves under the action of the moving block 23 and moves inside the movable groove 27, so that the limiting block 25 moves with it. During the movement of the limiting block 25, it pushes the blade placed on the support table 15 and can limit its two ends, thereby achieving the positioning of the blade and ensuring that the blade is not crooked when placed on the support table 15. Then, the blade is clamped by the clamping plate 14, and the rotation of the positive and negative screws 21 makes the limiting blocks 25 move away from each other and move away from both sides of the blade, so that processing can be carried out. The second telescopic cylinder 34 is electrically connected to an external power source. When the operator presses a switch to start the second telescopic cylinder 34, the cylinder retracts, causing the support platform 15 to descend. Simultaneously, the second limit rod 35 moves inside the base 1. The second motor 31 is also electrically connected to an external power source. When the operator presses a switch to start the second motor 31, the motor 31 rotates, causing the rotating rod 3 to rotate. The connecting frame 12 rotates accordingly under the action of the rotating rod 3, and the connecting ring 32 moves inside the rotating groove 33. This allows the connecting frame 12 to rotate the blade, enabling the blade to be flipped. Then, the extension of the second telescopic cylinder 34 causes the support platform 15 to rise, bringing the support platform 15 into contact with the lower surface of the blade, thus providing support.

[0026] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
