Description

Technical Field

[0001] This utility model relates to the field of cutting tool processing technology, specifically to a hole-opening device with positioning function. Background Technology

[0002] Cutting tools play a crucial role in machining and metal cutting. High-quality tools can improve machining efficiency, ensure machining accuracy, and reduce production costs. In the tool manufacturing process, drilling is a critical step, used to install tool holders, cooling holes, and other structures, directly affecting the tool's performance and lifespan. Traditional drilling methods, such as manual drilling, are difficult to guarantee accuracy, easily leading to problems such as hole position deviations and inconsistent hole diameters; manual operation or the use of simple mechanical drilling tools results in slow processing speeds, which cannot meet the needs of large-scale production.

[0003] Currently, the existing patent publication number CN210731078U proposes a tool opening device for machining non-standard PCD forming milling cutters, including an overall shell, a transmission belt, a drill, and a motor. The transmission belt is installed inside the overall shell, and a fixed seat is provided on the upper surface of the transmission belt. Control boxes are symmetrically arranged on both the front and rear sides of the interior of the overall shell, and slots are opened on the inner surface of the control boxes. There are two slots distributed on the front surface of the control boxes, with the drill connected to the front of the upper slot and the ejector pin connected to the front of the lower slot. A storage box is provided at the bottom of the interior of the overall shell, and a motor is installed on the rear side of the overall shell.

[0004] With the above setup, the existing technology uses an assembly line method to perform hole-making on non-standard PCD forming milling cutters, processing three milling cutters at a time, which greatly improves the processing efficiency of milling cutters while ensuring the processing accuracy.

[0005] However, the existing non-standard PCD forming milling cutter tool opening device has the following defects during operation:

[0006] In the existing technology, the fixed seats are arranged at equal intervals above the transmission belt. Due to the small supporting force of the transmission belt, local pressure will cause the transmission belt to deform in the pressure area, which may lead to belt twisting or local dents. When the drill performs hole-making on three milling cutters at the same time during the downward process, the corresponding pressure area of ​​the transmission belt will be dented, affecting the hole-making accuracy. Utility Model Content

[0007] This utility model aims to provide a hole-opening device with positioning function, mainly to solve the technical problems of the existing technology, such as the low support force of the conveyor belt, the deformation of the conveyor belt in the pressure area when local pressure is applied, and the concave situation of the conveyor belt in the corresponding pressure area when the drill performs hole-opening on three milling cutters at the same time during the downward process, which affects the accuracy of hole opening.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0009] A hole-opening device with positioning function includes a housing and a conveyor belt. The housing has symmetrically arranged mounting plates, and a slider is slidably connected within each mounting plate. Mounting grooves are formed on opposite sides of each mounting plate, and sliding grooves are symmetrically formed on the sidewalls of each mounting groove. Support components for supporting the conveyor belt are slidably connected within each sliding groove. One end of the slider passes through the mounting groove. Several first toothed blocks are fixedly connected to both sides of the slider within the mounting groove. Gears are symmetrically arranged and rotatably connected to the inner wall of the mounting groove. Each gear meshes with the first toothed blocks and the support components. A limiting component is provided on the inner wall of the mounting groove to limit the rotation of the gears, and the limiting component cooperates with the first toothed blocks and the slider.

[0010] The working principle and beneficial effects of this utility model:

[0011] 1. Working Principle: When drilling is required for the cutting tool, (the motor connected to the internal rotating drum is started, driving the transmission belt to rotate. The operator places the cutting tools to be processed into the fixed seat in batches, starts the motor connected to the gear, and drives the slider to move through the gear. The slider moves up and down under the influence of the gear, causing the drill and the ejector pin to move up and down in front of the control box. The upper drill is started to drill the cutting tool from shallow to deep). (The part in parentheses is cited prior art, which is not described in detail in this application. When the slider moves down, it drives the first tooth block down.) As the first toothed block engages with the gear, its downward movement causes the gear to rotate. The gear then engages with the support assembly, causing the support assembly to move upward. When the first toothed block continues to move downward and disengages from the gear, it engages with the limiting assembly again. The first toothed block then drives the limiting assembly to rotate until it abuts against the gear. When the support assembly abuts against the conveyor belt, a hole is made. After the hole is made, the slider moves upward, causing the first toothed block to move upward. After the first toothed block disengages from the limiting assembly, it engages with the gear again. The upward movement of the first toothed block causes the gear to rotate in the opposite direction, and the reverse rotation of the gear causes the support assembly to move downward.

[0012] 2. Beneficial effects:

[0013] Existing technology arranges fixed seats at equal intervals above the transmission belt, with three seats evenly spaced in each row, corresponding one-to-one with three drills above. Therefore, when using this device to drill holes in non-standard PCD forming milling cutters, the drills can drill holes in three milling cutters simultaneously during the downward movement, improving processing efficiency, saving processing time, and thus reducing overall production costs. However, due to the low support force of the conveyor belt, localized pressure can cause deformation of the conveyor belt in the pressure area, potentially leading to belt twisting or other problems. The conveyor belt in the corresponding pressure area will dent when the drill is drilling three milling cutters at once during its descent, affecting the drilling accuracy. This solution solves the technical problem of localized deformation of the conveyor belt under pressure when the drill is drilling three milling cutters at once during its descent, which affects the drilling accuracy. This is achieved by setting a mounting groove in the mounting box, and through the interaction of the support component, limit component, first tooth block and gear in the mounting groove, the support component abuts against the conveyor belt when the drill is drilling the cutters.

[0014] Preferably, the support assembly includes a slide rod slidably connected within a slide groove, with a connecting plate fixedly connected to the other end of the slide rod. A plurality of second toothed blocks are fixedly connected to one side of the connecting plate, and these second toothed blocks mesh with a gear. A support rod is fixedly connected to the outer wall of the connecting plate, with the other end of the support rod extending into a mounting groove and also fixedly connected to the support plate. When it is necessary to drill a hole for the tool, the slide block moves downward, causing the first toothed block to move downward. Since the first toothed block meshes with the gear, its downward movement causes the gear to rotate. Since the gear meshes with the second toothed blocks, the gear's rotation drives the second toothed blocks to move upward. The upward movement of the second toothed blocks causes the connecting plate to move upward, which in turn causes the slide rod and support rod to move upward. The support rod moves upward, causing the support plate to move upward. When the slider continues to move downward, it causes the first toothed block to move downward and disengage from the gear, then re-engages with the limiting component. The first toothed block moves downward, causing the limiting component to rotate. When the limiting component abuts against the gear, the support plate rises to abut against the conveyor belt. After the hole is opened, the slider causes the first toothed block to move upward. The first toothed block moves upward, causing the limiting component to rotate in the opposite direction and disengage from the gear. The slider continues to cause the first toothed block to move upward, disengage from the limiting component, and re-engage with the gear, causing the gear to rotate in the opposite direction. The gear rotates in the opposite direction, causing the second toothed block to move downward. The second toothed block moves downward, causing the connecting plate to move downward. The connecting plate moves downward, causing the slide rod, support rod, and support plate to move downward.

[0015] Preferably, the gear is located between the first tooth block and the second tooth block and is meshed with them; the gear being located between the first tooth block and the second tooth block allows the first tooth block and the second tooth block to move in opposite directions.

[0016] Preferably, the first and second tooth blocks are staggered; the gear is located between the first and second tooth blocks, and the staggered arrangement of the first and second tooth blocks allows the first and second tooth blocks to move in opposite directions while alternating within a limited space.

[0017] Preferably, the limiting component includes a half gear located in the mounting groove and rotatably connected by a spring shaft, and a pawl is fixedly attached to the outer wall of the half gear; when the slider moves the first tooth block downward and disengages from the tooth block and engages with the half gear, the downward movement of the first tooth block will drive the half gear to rotate, and the half gear will drive one end of the pawl to abut against the gear to prevent the gear from rotating back. When the slider moves upward and drives the first tooth block upward, the first tooth block drives the half gear to rotate in the opposite direction, and the reverse rotation of the half gear will drive the pawl to disengage from the tooth block. The pawl is provided to prevent the gear from rotating back, which would cause the support plate to fail to abut against the conveyor belt.

[0018] Preferably, a rubber block is fixed to the upper end face of the support plate; when the drill makes a hole in the tool, the support plate abuts against the conveyor belt, and the rubber block can act as a buffer to absorb part of the impact force, protect the support plate, and reduce the friction between the conveyor belt and the support plate.

[0019] Preferably, a protective shell is snapped into one side of the mounting slot, and the outer wall of the protective shell is symmetrically provided with clearance grooves. The support rod is slidably connected to the clearance grooves, and a handle is fixedly connected to the outer wall of the protective shell. When the machine is running, the protective shell is snapped into the mounting slot, which effectively blocks external collisions and protects the parts in the mounting slot from damage.

Detailed Implementation

[0028] 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.

[0029] like Figures 1-7The diagram illustrates an opening device with a positioning function, comprising a housing 1 and a conveyor belt 2. The housing 1 has symmetrically arranged mounting plates 3, with sliders 4 slidably connected within each mounting plate 3. Mounting grooves 5 are formed on opposite sides of each mounting plate 3, and sliding grooves 6 are symmetrically formed on the sidewalls of each mounting groove 5. Support components for supporting the conveyor belt 2 are slidably connected within each sliding groove 6. One end of each slider 4 passes through a mounting groove 5, and several first toothed blocks 7 are fixedly connected to both sides of the slider 4 within the mounting groove 5. The inner walls of the mounting groove 5 are symmetrically arranged and rotatably connected. A gear 13 is connected to the first tooth block 7 and the support assembly. The support assembly includes a slide rod 8 slidably connected within a slide groove 6. A connecting plate 9 is fixedly connected to the other end of the slide rod 8. Several second tooth blocks 10 are fixedly connected to one side of the connecting plate 9, and the second tooth blocks 10 mesh with the gears 13. The first tooth blocks 7 and the second tooth blocks 10 are staggered, with the gear 13 located between the first tooth blocks 7 and the second tooth blocks 10. A support rod 11 is fixedly connected to the outer wall of the connecting plate 9, and the other end of the support rod 11 extends into a mounting groove 5. A support plate 12 is fixedly connected to the conveyor belt 2. When the drill is drilling into the tool, the support plate 12 abuts against the conveyor belt 2 to prevent local deformation due to pressure. A rubber block 19 is fixedly connected to the upper end face of the support plate 12. The rubber block 19 can act as a buffer, absorbing part of the impact force and protecting the support plate 12. At the same time, it reduces the friction between the conveyor belt 2 and the support plate 12. A protective shell 16 is snapped into one side of the mounting groove 5 to effectively block external collisions and protect the parts in the mounting groove 5 from damage. The outer wall of the protective shell 16 is symmetrically provided with clearance grooves 17. The support rod 11 is slidably connected to the clearance groove 17. The outer wall of the protective shell 16 is fixedly connected to the handle 18. The inner wall of the mounting groove 5 is provided with a limiting component for limiting the gear 13. The limiting component is used in conjunction with the first tooth block 7 and the slider 4. The limiting component includes a half gear 14 located in the mounting groove 5 and rotatably connected by a spring shaft. The outer wall of the half gear 14 is fixedly connected to a pawl 15. When one end of the pawl 15 abuts against the gear 13, it prevents the gear 13 from rotating, which would cause the support plate 12 to fail to abut against the conveyor belt 2.

[0030] As can be seen from the above, the specific embodiments of this utility model are as follows:

[0031] When drilling is required for the cutting tool, (the motor connected to the internal rotating drum is started, driving the transmission belt to rotate. The operator places the cutting tools to be processed into the fixed seat in batches, starts the motor connected to the gear, and drives the slider to move through the gear. The slider moves up and down under the influence of the gear and the telescopic spring, causing the drill and the ejector pin to move up and down in front of the control box. The upper drill is started to drill the cutting tool from shallow to deep). (The part in parentheses is cited prior art, which is not described in detail in this application.) The slider 4 slides down, causing the first tooth block 7 to move down. Since the first tooth block 7 is meshed with the gear 13, the downward movement of the first tooth block 7 causes the gear 13 to rotate. Since the second tooth block 10 is meshed with the gear 13, the rotation of the gear 13 drives the second tooth block 10 to move up. The upward movement of the second tooth block 10 causes the connecting plate 9 to move up. The upward movement of the connecting plate 9 causes the slide rod 8 to move up along the slide groove 6. At the same time, the upward movement of the connecting plate 9 causes the support rod 11 to move up. The upward movement of the support rod 11 causes the support plate to move up. As the support plate 12 moves upward, the slider 4 drives the first toothed block 7 to continue moving downward, disengaging from gear 13 and engaging with half gear 14. The downward movement of the first toothed block 7 drives the half gear 14 to rotate, which in turn drives the pawl 15 to rotate. After the pawl 15 rotates, one end abuts against gear 13, preventing gear 13 from rotating. When the support plate 12 moves upward and abuts against the conveyor belt 2, a hole is made. After the hole is made, the slider 4 moves upward, driving the first toothed block 7 to move upward. The upward movement of the first toothed block 7 drives the half gear 14 to rotate in the opposite direction. 14 rotates in the opposite direction, causing pawl 15 to rotate in the opposite direction and disengage from gear 13. Slider 4 drives the first tooth block 7 to continue moving upward and disengage from half gear 14. After disengaging from half gear 14, the first tooth block 7 meshes with gear 13. The first tooth block 7 drives gear 13 to rotate in the opposite direction. The gear 13 rotates in the opposite direction, causing the second tooth block 10 to move downward. The second tooth block 10 moves downward, causing connecting plate 9 to move downward. The connecting plate 9 moves downward, causing slide bar 8, support rod 11 and support plate 12 to move downward. Then, conveyor belt 2 continues to drive the next row of cutters to move below the drill.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model.
