Description

Technical Field

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

[0002] Clamping devices for tool production are mechanical devices used to fix workpieces during the tool production process. Through structures such as bases and clamping components, they stably clamp tool blanks or semi-finished products during cutting, grinding and other processing stages, ensuring processing accuracy and safety. They also often have adjustment functions to adapt to different processing needs, making them an important auxiliary tool for improving tool production efficiency and quality.

[0003] Utility model patent CN218285111U discloses a clamping device for tool manufacturing, including a base plate and multiple support columns at the top of the base plate; a worktable is welded to the top of the multiple support columns, the top of the worktable is provided with a first moving groove and a second moving groove, a first connecting block and a second connecting block are welded to the side of the worktable, a fourth telescopic rod is fixedly connected to the side of the first connecting block by bolts, and a first fixing block is fixedly connected to the side of the fourth telescopic rod by screws, which is close to the inner wall of the first moving groove. The side of the first fixing block is provided with bolt holes. This clamping device for tool manufacturing facilitates the collection of debris, is suitable for grinding tools of different radii and lengths, saves manpower, and improves efficiency.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: Existing clamping devices can clamp and process multiple tools, but when a single tool is finished and needs to be removed, there is a problem that it cannot be moved out individually because the moving mechanism is fixed as a whole. All tools need to move with the same moving mechanism, which significantly affects processing efficiency in batch processing scenarios. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a clamping device for tool production, which can effectively solve the problem that in the existing technology, a single set of tools cannot be moved independently after processing and must move with the overall moving mechanism, resulting in low batch processing efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a clamping device for tool production, including a clamping device body, a processing box, and a grinding device. Several clamping device bodies are provided, and these bodies are arranged at equal distances. The grinding device is installed on the back side of the inner wall of the processing box. A movable conveying assembly is provided on the inner side of the bottom of the inner wall of the processing box. The movable conveying assembly includes a mounting groove. A drive motor is installed on the front side of the inner wall of the mounting groove. A reducer is installed at the output end of the drive motor. A conveying screw is installed on the back side of the reducer. A semi-screw sleeve is threaded to the bottom of the conveying screw. A movable plate is installed at the bottom of the semi-screw sleeve. The clamping device body is installed on the inner side of the movable plate.

[0008] The processing box has a movable reset assembly on its front side. The movable reset assembly includes a fixed slot. A stepper motor is installed on the back of the inner wall of the fixed slot. A reset screw is installed at the output end of the stepper motor. An electric push rod is installed on the rear side of the bottom of the inner wall of the mounting slot. A lifting plate is installed at the output end of the electric push rod. The rear side of the bottom of the inner wall of the fixed slot is connected to the rear side of the top of the inner wall of the mounting slot. The stepper motor is electrically connected to a controller via wires. The controller is electrically connected to a drive motor via wires. The controller is also electrically connected to a time relay via wires.

[0009] The above solution involves a drive motor that is reduced in speed by a reducer to rotate a conveying screw. Through the threaded transmission between the semi-screw sleeve and the screw, the moving plate moves axially along the mounting groove, thereby achieving synchronous conveying of multiple clamping device bodies. In conjunction with the moving reset assembly, an electric push rod pushes a lifting plate to receive the processed clamping device body. A stepper motor moves it forward along the fixed groove to the unloading position via a reset screw, solving the problem that a single set of tools cannot be moved out independently and achieving continuous unloading in batch processing.

[0010] Furthermore, a limiting groove is formed on the outer side of the inner wall of the mounting groove, and a slider is slidably connected to the inner wall of the limiting groove. The inner side of the slider is installed with the outer side of the moving plate. A sliding groove is formed on the outer side of the inner wall of the fixing groove, and the back side of the inner wall of the sliding groove is connected to the back side of the inner wall of the limiting groove. The slider can slide in the sliding groove.

[0011] The above scheme restricts the movement trajectory of the moving plate by setting a limiting groove and a slider on the outside of the mounting groove, ensuring that it moves in a straight line along the axial direction. The sliding groove on the outside of the fixed groove is connected to the limiting groove. When the slider slides from the limiting groove into the sliding groove, the clamping device body switches from the conveying track to the reset track, realizing the path switching between the processing position and the unloading position.

[0012] Furthermore, an electromagnetic block is installed on the back side of the inner wall of the limiting groove, the electromagnetic block is magnetically connected to the slider, a proximity sensor is installed on the top of the lifting plate, and the controller is electrically connected to the electromagnetic block and the proximity sensor through wires.

[0013] The above scheme uses the magnetic attraction of the electromagnetic block to the slider, which makes the finished clamping device body stably rest on the lifting plate. After the proximity sensor detects the slider, it triggers the controller, which synchronously controls the electric push rod and time relay to start and drive the motor to stop. The stepper motor is started and stopped at regular intervals, realizing the automatic switching between processing and unloading.

[0014] Furthermore, a movable groove is provided on the front side of the inner side of the mounting groove, the front side of the bottom of the limiting groove is connected to the top of the movable groove, a gas spring is installed on the bottom of the inner wall of the movable groove, a support plate is installed on the top of the gas spring, and a movable rod is installed on the bottom of the support plate.

[0015] The above scheme utilizes the cooperation between the gas spring and the support plate to provide a reset force during clamping. Pressing down on the moving rod compresses the spring, allowing the clamping device body to be inserted into the moving slot. After releasing, the spring pushes the support plate upward, causing the semi-screw sleeve to engage with the conveying screw, thus achieving rapid clamping and power connection.

[0016] Furthermore, a movable rod is installed at the bottom of the support plate, and a limiting post is movably connected to the surface of the movable rod. The bottom of the limiting post is installed with the bottom of the inner wall of the moving groove.

[0017] The above solution, through the cooperation of the movable rod and the limiting post, limits the movement range of the support plate, prevents excessive shaking when the gas spring returns to its original position, and ensures the stability of the clamping process.

[0018] Furthermore, a battery is electrically connected to the inner side of the bottom of the clamping device body via a wire, and a protective box is installed on the outer side of the battery. The top of the protective box is installed with the bottom of the clamping device body.

[0019] The above solution provides an independent power source for the clamping device body via a battery, and the protective box isolates the circuit components, ensuring a stable and safe power supply during movement.

[0020] Furthermore, a connecting ring is installed on the back of the conveying screw, and a support ring is movably connected to the surface of the connecting ring. The top of the support ring is installed with the top of the inner wall of the mounting groove.

[0021] The above solution uses a connecting ring and a support ring to support the rear end of the conveying screw, reducing radial sway during screw rotation and improving transmission stability.

[0022] Furthermore, a movable bearing is mounted on the front side of the reset screw, and a mounting block is mounted on the top of the movable bearing. The top of the mounting block is mounted to the front side of the top of the inner wall of the fixing groove.

[0023] The above solution uses a movable bearing and mounting block to fix the front end of the reset screw, allowing the screw to rotate freely while bearing axial force, thus ensuring the reliability of the reset transmission.

[0024] Beneficial effects

[0025] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0026] I. This utility model achieves synchronous conveying and processing of multiple clamping device bodies by setting up a drive motor, conveying screw, stepper motor, reset screw and other components in coordination. When a single tool is finished, the electric push rod and reset screw can push it to the unloading position independently without moving other groups. This avoids the downtime and waiting problem caused by traditional whole movement, and allows the clamping, processing and unloading processes to be carried out in parallel, shortening non-processing time and increasing the unit time productivity.

[0027] II. This utility model utilizes the linkage mechanism of electromagnetic blocks, proximity sensors, and controllers. When the completed clamping device body moves to the lifting plate, the electromagnetic blocks are fixed in position by magnetic adsorption. The proximity sensors detect in real time and trigger the controller to automatically shut down the drive motor, start the electric push rod and stepper motor to reset and unload the material. This reduces human operation errors, ensures precise connection of actions at each station, and is especially suitable for long-term continuous processing scenarios, reducing labor costs and improving processing stability.

[0028] Third, this utility model, through the combination of gas spring, support plate, limiting groove and slider, only requires manual pressing of the moving rod to complete the engagement of the semi-screw sleeve and the conveying screw during clamping, without the need for manual alignment of the threads. The connection design of the limiting groove and the sliding groove provides precise guidance for the slider, ensuring that the clamping device body moves along a fixed trajectory during the conveying and unloading stages, avoiding processing errors caused by deviation, ensuring the grinding accuracy of the cutting tool, and the mechanical limiting of the moving rod and the limiting post further improves the clamping stability and reduces the impact of equipment vibration on the processing quality.

An electromagnetic block 9 is installed on the back side of the inner wall of the limiting groove 6. The electromagnetic block 9 is magnetically connected to the slider 7. The electromagnetic block 9 is used to attract and move the processed clamping device body 1 to the position on the lifting plate 55. A proximity sensor 10 is installed on the top of the lifting plate 55 to control the movement of the clamping device body 1.

Gas spring 12 is installed at the bottom of inner wall of moving groove 11. Support plate 13 is installed on the top of gas spring 12. Moving rod 14 is installed at the bottom of support plate 13. Gas spring 12 provides reset spring force through support plate 13. When clamping, pressing moving rod 14 compresses gas spring 12. After releasing, gas spring 12 pushes support plate 13 upward, so that half thread sleeve 45 engages with conveying screw 44 to achieve quick clamping. Electromagnetic block 9 and proximity sensor 10 are existing technologies.

[0042] A movable rod 15 is installed at the bottom of the support plate 13. A limiting post 16 is movably connected to the surface of the movable rod 15. The bottom of the limiting post 16 is installed at the bottom of the inner wall of the moving groove 11 to limit the movement range of the support plate 13 and prevent shaking during assembly.

For stability and safety, a connecting ring 19 is installed on the back of the conveying screw 44, and a support ring 20 is movably connected to the surface of the connecting ring 19. The top of the support ring 20 is installed on the top of the inner wall of the mounting groove 41 to reduce radial sway when the conveying screw 44 rotates and improve transmission stability. A movable bearing 21 is installed on the front of the reset screw 53, and a mounting block 22 is installed on the top of the movable bearing 21. The top of the mounting block 22 is installed on the front side of the top of the inner wall of the fixed groove 51 to bear the axial force of the reset screw 53 and ensure reliable unloading transmission. The battery 17 is existing technology.

[0043] Working principle: During use, the user first holds the moving rod 14 and applies downward pressure, causing the support plate 13 to move downward against the elastic force of the gas spring 12. At this time, the clamping device body 1, together with the bottom moving plate 46, is slowly pushed into the moving groove 11 track on the inner wall of the processing box 2 until the moving plate 46 is completely inside the moving groove 11. Then, the moving rod 14 is released, and the gas spring 12 generates an upward restoring force due to elastic deformation, pushing the support plate 13 vertically upward along the inner wall of the moving groove 11. The support plate 13 is connected by the bottom connecting rod. The moving plate 46 moves upward synchronously, and the semi-screw sleeve 45 at the top of the moving plate 46 moves upward accordingly until the internal thread hole of the semi-screw sleeve 45 is fully engaged with the external thread at the bottom of the conveying screw 44. During this process, the slider 7 on the outside of the moving plate 46 slides into the limiting groove 6 on the inner wall of the mounting groove 41. When the slider 7 is fully engaged in the limiting groove 6, the semi-screw sleeve 45 and the conveying screw 44 form a stable threaded transmission connection. At this time, the user can accurately fix the tool to be processed on the clamping device body 1 and complete the assembly preparation of a single clamping device body 1.

[0044] After assembly, manually press the start button of drive motor 42. The output shaft of drive motor 42 starts to rotate, and the power is transmitted to the input end of reducer 43 through the coupling. After the speed is reduced and the torque is increased by reducer 43, the output end drives the conveying screw 44 to rotate clockwise. The rotational motion of the conveying screw 44 is converted into the linear motion of the half-screw sleeve 45. The half-screw sleeve 45 is guided by the slider 7 in the limiting groove 6 and can only move axially along the limiting groove 6. It cannot rotate with the screw. Therefore, the half-screw sleeve 45 drives the clamping device body 1 above it through the moving plate 46 to move towards the grinding device 3 on the rear side of the processing box 2 at a constant speed. In the first processing flow, the system has not yet formed a closed loop. The user can preset the time delay shutdown function of the time relay 57 through the controller 56. After the motor stops, repeat the above assembly steps, put the second set of clamping device body 1 into the moving groove 11 and complete the tool fixing, and repeat the above operation.

[0045] Until the first set of clamping device body 1 moves to the rear of the processing box 2, the tool it carries is just aligned with the working surface of the grinding wheel of the grinding device 3 and the grinding process begins. After the grinding process, the user continues to start the drive motor 42, and the conveying screw 44 continues to rotate, pushing the first set of semi-screw sleeves 45 that have been processed forward to the front position of the lifting plate 55 behind the mounting groove 41. At this time, the threaded connection between the semi-screw sleeve 45 and the conveying screw 44 gradually disengages, while the electromagnetic block 9 on the inner wall of the limiting groove 6 remains energized and continuously generates magnetic attraction, adsorbing the slider 7 onto the inner wall behind the limiting groove 6, so that the moving plate 46, the semi-screw sleeve 45 and the clamping device body 1 are stably stopped on the top of the lifting plate 55. After the proximity sensor 10 installed on the top of the lifting plate 55 detects the slider 7, it immediately sends an electrical signal to the controller 56. After receiving the signal, the controller 56 first cuts off the power of the drive motor 42 to stop it from rotating, so that the second set of clamping device body 1 drives the tool to stay on the processing position for processing, and at the same time sends a start command to the electric push rod 54.

[0046] The telescopic rod of the electric push rod 54 extends upward, pushing the moving plate 46 to move slowly along the slide groove 8. The movement of the moving plate 46 causes the slider 7 to gradually disengage from the limiting groove 6 and enter the slide groove 8 on the inner wall of the front fixing groove 51 of the processing box 2. The internal thread hole at the top of the slider 7 gradually engages with the external thread at the bottom of the reset screw 53 in the fixing groove 51. At this time, the controller 56 synchronously starts the stepper motor 52. The output shaft of the stepper motor 52 drives the reset screw 53 to rotate. Since the slider 7 moves into the inside of the slide groove 8, the rotational motion of the reset screw 53 is converted into the horizontal forward movement of the half-screw sleeve 45. The half-screw sleeve 45 pushes the clamping device body 1 forward through the moving plate 46. After the time set by the time relay 57, the time relay 57 sends a stop signal to the controller 56, and the stepper motor 52 is de-energized and stops rotating. At this time, the clamping device body 1 has moved to the unloading position on the front side of the processing box 2, and the user can remove the processed tool.

[0047] After unloading, the user moves the clamping device body 1 to the inside of the moving slot 11 by hand, and then presses the moving rod 14 down to drive the support plate 13 to compress the gas spring 12. Then, the clamping device body 1, the moving plate 46 and the half-screw sleeve 45 are moved to the top of the support plate 13. The moving rod 14 is released and the gas spring 12 is reset. The support plate 13 is pushed up to lift the moving plate 46, so that the half-screw sleeve 45 is aligned with the bottom thread of the conveying screw 44 again. The tool to be processed is clamped to the inside of the clamping device body 1. Due to the existing grinding time, the user has enough time to complete the unloading, cleaning of the clamping device body 1, clamping of new tools and other operations.

[0048] After the cutting tool carried by the second set of clamping device body 1 has finished processing, the user manually starts the drive motor 42 to push the processed tool set to the lifting plate 55. At this time, each set of clamping device body 1 continues to move. The third set of clamping device body 1 moves to the processing position for processing. After the proximity sensor 10 continues to detect, the controller 56 shuts off the drive motor 42 and starts the electric push rod 54 and the stepper motor 52 to complete the unloading. At the same time, the assembly of this set of processing device body continues to repeat. This cycle is repeated to form a closed-loop workflow of clamping, conveying, processing, unloading and re-clamping, ensuring that multiple sets of cutting tools are processed continuously and avoiding the shutdown of the entire equipment due to the unloading of a single set, which significantly improves the efficiency of batch production.

[0049] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
