Abstract
Description
Technical Field
[0001] This utility model relates to the field of clamping fixture technology, specifically to a clamping fixture for cutting tool processing. Background Technology
[0002] A cutting tool is a cutting tool used to cut various materials. Its main function is to apply external force to separate the material at the cutting edge, thereby achieving the cutting purpose. Cutting tools play an indispensable role in many industries such as metal processing, wood processing, plastic processing, and paper processing. During the processing, cutting tools can be roughed, heat treated, and finished. In the roughing and finishing processes, such as turning, milling, or grinding, the cutting tool needs to be clamped and fixed by a clamping fixture to ensure that the cutting tool is accurately positioned in the predetermined position during clamping, maintaining the subsequent cutting accuracy, surface quality, and production efficiency.
[0003] CN216326125U discloses a clamping fixture for crankshaft cutter welding repair, relating to the field of fixing fixture technology. This utility model includes a base, with support plates fixed to both ends of the base surface; a U-shaped frame fixed to the top of the support plates; shaft seat support frames slidingly fitted inside the two U-shaped frames; adjusting screws threadedly connected to the bottom of both U-shaped frames; a rectangular strip seat located on the base surface and between the two U-shaped frames; a cutter clamping seat arrayed on the surface of the rectangular strip seat; and fastening screws threadedly connected to both sides of the bottom end of the cutter clamping seat. In this utility model, the shaft seat support frames at both ends of the base support the main shafts at both ends of the crankshaft cutter, and the cutter clamping seat clamps and limits the individual cutter discs, clamping and fixing the entire crankshaft cutter, improving the accuracy of crankshaft cutter welding repair operations. Simultaneously, under the action of the adjusting screws and fastening screws, crankshaft cutters with different shaft spacing between the cutter discs are clamped, allowing for clamping and repair operations on different models of crankshaft cutters.
[0004] While the existing technology CN216326125U has many advantages in use, it still has the following problems: its clamping stability for the cutter is not perfect. It only clamps the cutter laterally on both sides, but the cutter will still move longitudinally during processing, resulting in an unstable overall posture of the cutter and affecting the processing quality of the subsequent cutter. Utility Model Content
[0005] To address the problems in the existing technology, this utility model provides a cutting tool clamping fixture.
[0006] The technical solution adopted by this utility model to solve its technical problem is a cutting tool clamping fixture, including a processing table, a clamping plate and a dual-axis motor. The upper outer wall of the processing table is provided with movable grooves on both sides. A clamping block is provided inside the movable groove. The outer walls on both sides of the clamping block are provided with storage grooves. A clamping plate is provided inside the storage grooves. A sliding groove is provided inside the clamping plate. A slider is slidably installed inside the sliding groove. A dual-axis motor is installed on one side of the inner wall of the clamping block.
[0007] By adopting the above technical solution, the clamping blocks can move horizontally within the movable slot. When the operator places the cutter on the upper surface of the processing table and it is positioned between the clamping blocks, the cutter can be horizontally clamped and fixed by the two clamping blocks, and the cutter can be vertically clamped and fixed by the clamping plate. This ensures the stability of the cutter clamping on the upper surface of the processing table, improves the overall stability of the cutter's posture, and ensures the processing quality of the subsequent cutter. The dual-axis motor drives the screw to rotate, which can adjust the position of the clamping plate to ensure that the clamping plate can adapt to cutters of different sizes. This ensures the stability of the cutter clamping while also ensuring the adaptability of the device.
[0008] Specifically, limit rods are installed on both sides of the inner wall of the storage slot, and the clamping block is slidably installed on the outside of the limit rods.
[0009] By adopting the above technical solution, the installation of the limiting rod ensures the stability and accuracy of the clamping block sliding in the storage slot. The clamping block can only move along the direction of the limiting rod, avoiding deviation or shaking during the adjustment process and ensuring the accuracy of the cutter clamping.
[0010] Specifically, a ball screw is installed on one side of the lower outer wall of the processing table, and the lower outer wall of the clamping block is connected to the ball screw by screws.
[0011] By adopting the above technical solution, the position of the ball screw can be precisely adjusted to meet the precise requirements of the clamping position during different cutting processes, and the screw connection method facilitates the disassembly and maintenance of the ball screw.
[0012] Specifically, the upper surface of the clamping block is higher than the upper surface of the processing table, and a first protective pad is adhered and fixed to the outer wall of one end of the clamping block.
[0013] By adopting the above technical solution, when the cutter is located on the upper surface of the processing table, the part of the clamping block protruding from the processing table can clamp and fix the cutter, avoiding interference between the clamping block and the processing table during the clamping process. In addition, the first protective pad plays a buffering role when clamping the cutter, preventing the clamping block from damaging the cutter and protecting the surface quality of the cutter.
[0014] Specifically, the dual-axis motor has screws on the outer walls of both ends, the screws are located inside the receiving groove, and the slider is threadedly connected to the outside of the screws.
[0015] By adopting the above technical solution, the dual-axis motor can synchronously drive the screws on both sides when it is running, which in turn can drive the slider to move. Since the slider is inside the slide groove, the clamping plates on both sides can open and close synchronously, ensuring the uniformity and stability of the clamping of the cutter, improving the clamping effect, and ensuring that the cutter will not shift or shake due to uneven clamping during the processing.
[0016] Specifically, a second protective pad is adhered and fixed to one side of the outer wall of the clamping plate, and the second protective pad is located inside the storage groove.
[0017] By adopting the above technical solution, when the clamping plate clamps the cutter, the second protective pad comes into contact with the cutter, further protecting the cutter and preventing the clamping plate from directly contacting the cutter and scratching the cutter surface.
[0018] Specifically, the inner wall of the groove and the outer wall of the slider are both designed in a stepped shape, and the slider is distributed inside the storage groove.
[0019] By adopting the above technical solution, the slide groove ensures that the sliding trajectory of the slider is controlled and smooth, and can limit the movement trajectory of the clamping plate, ensuring that the clamping plate is located inside the storage groove, so as to realize the clamping of the cutter by the clamping plate.
[0020] The beneficial effects of this utility model are:
[0021] (1) The cutting tool clamping fixture described in this utility model can achieve longitudinal clamping and fixing of the cutting tool through the clamping plate, ensuring the stability of the cutting tool on the upper surface of the processing table, improving the overall stability of the cutting tool posture, and ensuring the processing quality of the subsequent cutting tool.
[0022] (2) The cutting tool clamping fixture described in this utility model has a dual-axis motor driving the screw to rotate, which can adjust the position of the clamping plate, ensuring that the clamping plate can adapt to cutting tools of different sizes, ensuring the stability of cutting tool clamping, and ensuring the adaptability of the device.

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0030] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the cutting tool clamping fixture of this utility model includes a processing table 1, a clamping plate 2, and a dual-axis motor 3. The upper outer wall of the processing table 1 has movable grooves 13 on both sides. A clamping block 11 is provided inside the movable groove 13. A storage groove 12 is provided on both sides of the outer wall of the clamping block 11. A clamping plate 2 is provided inside the storage groove 12. A sliding groove 22 is provided inside the clamping plate 2. A slider 23 is slidably installed inside the sliding groove 22. A dual-axis motor 3 is installed on one side of the inner wall of the clamping block 11.
[0031] During use, the clamping blocks 11 can move horizontally within the movable slot 13. When the operator places the cutter on the upper end of the processing table 1 and between the clamping blocks 11, the two clamping blocks 11 can achieve horizontal clamping and fixation of the cutter, and the clamping plate 2 can achieve vertical clamping and fixation of the cutter, ensuring the stability of the cutter on the upper surface of the processing table 1, improving the overall stability of the cutter's posture, and ensuring the processing quality of the cutter. The dual-axis motor 3 drives the screw 31 to rotate, which can adjust the position of the clamping plate 2, ensuring that the clamping plate 2 can adapt to cutters of different sizes, ensuring the stability of the cutter clamping while ensuring the adaptability of the device.
[0032] To limit the movement trajectory, for example, such as Figure 2 As shown, limit rods are installed on both sides of the inner wall of the storage groove 12, and the clamping block 11 is slidably installed on the outside of the limit rods.
[0033] During use, the installation of the limiting rod ensures the stability and accuracy of the sliding of the clamping block 11 within the storage slot 12. The clamping block 11 can only move along the direction of the limiting rod, avoiding deviation or shaking during adjustment and ensuring the accuracy of the cutter clamping.
[0034] To drive movement, for example, such as Figure 2As shown, a ball screw 14 is installed on one side of the lower outer wall of the processing table 1, and the lower outer wall of the clamping block 11 is connected to the ball screw 14 by screws.
[0035] When in use, the ball screw 14 can precisely adjust the position of the clamping block 11 to meet the precise requirements of the clamping position during different cutting processes, and the screw connection method facilitates the disassembly and maintenance of the ball screw 14.
[0036] To protect the cutter, for example, such as Figure 3 As shown, the upper surface of the clamping block 11 is higher than the upper surface of the processing table 1, and a first protective pad 15 is adhered and fixed to the outer wall of one end of the clamping block 11.
[0037] When in use, when the cutter is located on the upper surface of the processing table 1, the part of the clamping block 11 protruding from the processing table 1 can clamp and fix the cutter, avoiding interference between the clamping block 11 and the processing table 1 during the clamping process. In addition, the first protective pad 15 plays a buffering role when clamping the cutter, preventing the clamping block 11 from damaging the cutter and protecting the surface quality of the cutter.
[0038] To drive movement, for example, such as Figure 3 As shown, screws 31 are provided on the outer walls of both ends of the dual-axis motor 3. The screws 31 are located inside the receiving groove 12, and the slider 23 is threadedly connected to the outside of the screws 31.
[0039] When in use, the dual-axis motor 3 can synchronously drive the screws 31 on both sides, which in turn can drive the slider 23 to move. Since the slider 23 is inside the slide groove 22, the clamping plates 2 on both sides can open and close synchronously, ensuring the uniformity and stability of the cutter clamping, improving the clamping effect, and ensuring that the cutter will not shift or shake due to uneven clamping during processing.
[0040] To protect the cutter, for example, such as Figure 3 As shown, a second protective pad 21 is adhered and fixed to the outer wall of one side of the clamping plate 2, and the second protective pad 21 is located inside the storage groove 12.
[0041] When in use, when the clamping plate 2 clamps the cutter, the second protective pad 21 comes into contact with the cutter, further protecting the cutter and preventing the clamping plate 2 from directly contacting the cutter and scratching the cutter surface.
[0042] For example, to enable coordinated movement, such as... Figure 4 As shown, the inner wall of the slide 22 and the outer wall of the slider 23 are both designed in a stepped shape, and the slider 23 is distributed inside the storage groove 12.
[0043] In use, the slide groove 22 ensures that the sliding trajectory of the slider 23 is controlled and smooth, and can limit the movement trajectory of the clamping plate 2, ensuring that the clamping plate 2 is located inside the storage groove 12, so as to enable the clamping plate 2 to clamp the cutter in the future.
[0044] In use, the operator places the cutter to be processed on the upper end of the processing table 1, positioning the cutter appropriately between the two clamping blocks 11. The ball screw 14 rotates, causing the clamping blocks 11 to move horizontally within the movable grooves 13 on both sides of the upper outer wall of the processing table 1. The distance between the two clamping blocks 11 is precisely adjusted according to the size of the cutter until the two clamping blocks 11 initially clamp the cutter laterally.
[0045] The screws 31 at both ends of the dual-axis motor 3 rotate synchronously. Since the slider 23 is threaded to the outside of the screw 31 and located in the groove 22 inside the clamping plate 2, the rotation of the screw 31 drives the slider 23 to move in the groove 22, thereby driving the clamping plate 2 to move longitudinally in the storage groove 12 along the direction of the limiting rod. According to the thickness and other dimensions of the cutter, the position of the clamping plate 2 is adjusted until the cutter is firmly clamped in the longitudinal direction.
[0046] It should be noted that this utility model is a cutting tool clamping fixture. All components in this utility model are known to those skilled in the art, and their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
