Description

Technical Field

[0001] This invention relates to the field of CNC machine tool technology, and in particular to a CNC machine tool auxiliary feeding device and its usage method. Background Technology

[0002] In the field of machining, CNC machine tools are core processing equipment, widely used for precision machining of various metal or non-metal materials such as milling and drilling. When using CNC machine tools, loading and unloading materials is an essential and frequent process. Currently, for loading small, medium, or heavy materials, manual handling is usually required to move the materials and insert them into the machining chamber of the machine tool for clamping.

[0003] However, in actual operation, the internal space of the machining chamber of a machine tool is usually quite limited, and high-speed rotating cutting tools are installed deep inside. When workers feed materials into the machine tool for positioning and clamping, their arms often need to be extended into the machine tool. This not only limits the operating view and makes alignment difficult, but also increases the safety risk of operators being accidentally injured by moving parts. Moreover, when it is necessary to move and adjust the materials for processing, since the materials have been partially or completely entered into the machine tool, the adjustment is extremely inconvenient. Especially for heavy materials, moving and turning them in a confined space is not only labor-intensive, but also easily causes the materials to collide with the machine tool or cutting tools, affecting the machining accuracy. Summary of the Invention

[0004] The purpose of this invention is to provide a CNC machine tool auxiliary feeding device and its usage method to solve the problems mentioned in the background art.

[0021] A rotating block, the side of which is rotatably interlocked with the middle of an adjacent connecting block via a pin;

[0022] Positioning grooves, a plurality of the positioning grooves are formed at the bottom of the rotating block;

[0023] A compression spring, which is fixed to the inner wall of the positioning groove;

[0024] The locking block is fixed to the bottom of the compression spring and is slidably connected to the inner cavity of the positioning groove. The locking block is slidably inserted into the inner cavity of the adjacent locking groove under the influence of gravity. The end of the push plate near the locking block is used to push the locking block upward.

[0025] A push bar is installed between the rotating block and the auxiliary component, and the push bar is used for meshing rotation relative to the two clamping blocks.

[0026] Preferably, the push bar includes:

[0027] An electric telescopic rod, wherein the electric telescopic rod is fixedly embedded in the top of the rotating block;

[0028] A rack is fixed to the telescopic end of the electric telescopic rod, and the rack is synchronously engaged with the bottom of two adjacent clamping blocks.

[0029] Preferably, the auxiliary component includes:

[0030] An elongation block is fixed to the top of a rotating block, and a rack is slidably connected to the middle of the elongation block;

[0031] A mating groove is formed through the middle and side of the elongated block, and two clamping blocks are respectively installed on the two sides of the mating groove;

[0032] A limiting groove is formed in the middle of the inner wall of the mating groove;

[0033] An arc-shaped groove is formed in the middle of the upper surface of the block.

[0034] Preferably, the clamping block includes:

[0035] A rotating shaft, the end of which is rotatably inserted into the side of the inner wall of the mating groove via a bearing;

[0036] A gear, which is fixed to the middle of the rotating shaft;

[0037] The clamping rod is fixed to the outer wall of the gear and is used to clamp and limit the processing material.

[0038] Preferably, the rack meshes with the outer walls of two opposing gears, and the top of the rack is movably inserted into the inner cavity of the limiting groove.

[0039] Preferably, the inner cavity of the arc-shaped groove has an arc-shaped structure with multiple rolling balls connected in a rolling manner, and the rolling balls are used for rolling and repositioning of materials in a non-clamped state.

[0040] A method for using a CNC machine tool auxiliary feeding device includes the following steps:

[0041] Step 1: Push the push rod to stretch the tension spring, and the push plate moves towards the locking block, causing the locking block to be pushed upward by the inclined surface of the push plate and slide out of the inner cavity of the locking slot. At this time, the position of the rotating block is not restricted.

[0042] Step 2: Move the rotating block so that its locking block moves in the inner cavity of the movable groove toward the protective strip, and rotate the auxiliary components on the rotating block out of the inner cavity of the machine tool body, so that the material to be processed can be more easily loaded into the inner cavity of the limit groove. The rolling of the ball makes the material loading adjustment convenient, and the drive of the electric telescopic rod moves the rack, which drives the two clamping blocks to clamp the material.

[0043] Step 3: Push the rotating block in the opposite direction so that it stands vertically on the slider. Move the elongated block back into the inner cavity of the machine tool body. At the same time, when the chuck rotates to the top of the chuck slot, it slides into the inner cavity of the chuck slot due to natural gravity and the elasticity of the compression spring, so that the rotating block can maintain a vertical state and the material can be carried on the elongated block for processing.

[0044] The technical effects and advantages of this invention are as follows:

[0045] (1) The present invention uses a combination of sliding components, pushing components, adjusting components and auxiliary components. By setting up sliding components and rotatable adjusting components, the operator can push the auxiliary components to the outside of the machine tool body for loading and orientation adjustment, avoiding the operational risk of the arm reaching into the machine tool, eliminating blind spots, and improving the safety of the loading process and the convenience of material adjustment.

[0046] (2) By using the combination of the push component and the adjustment component, the present invention achieves stable vertical positioning of the adjustment component in the working state by utilizing the cooperation of the block and the slot, so that the material can be rotated to the cutter head for processing. When adjustment is required, the block can be released by pushing the push plate in the component, so that the bearing block can move, improving the ease of material loading and unloading.

[0047] (3) The present invention uses the setting method of adjusting the clamping block to cooperate with the gear of the clamping block and the rack of the adjusting block to cooperate. The rack is driven by the electric telescopic rod. The meshing of the rack and the gear realizes the synchronous opening and closing of the two clamping rods, which makes it easy to clamp and fix the material immediately after it is in place, improves the stability of the material position on the bearing block, and improves the stability of the material during processing, thus improving the clamping efficiency.

[0048] (4) The present invention provides stable multi-point support for round bar materials by setting multiple balls in the arc groove on the bearing block. With the rolling characteristics of the balls, even when the heavy material is not clamped, the operator can easily roll and adjust the position of the material on the platform, which greatly reduces the labor intensity of auxiliary feeding, improves the convenience of material feeding and adjustment, and does not affect the processing accuracy.

Detailed Implementation

[0058] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0059] This invention provides, for example Figures 1-7 The image shows an auxiliary feeding device for a CNC machine tool.

[0060] Example 1: Includes a machine tool body 100, a slide rail 200, and a sliding assembly 300. The machine tool body 100 is an existing CNC machining tool used for milling materials. The slide rail 200 is installed in the inner cavity of the machine tool body 100 and is an inverted T-shaped rail. The sliding assembly 300 slides along a straight track on the slide rail 200, facilitating sliding adjustment of the sliding assembly 300 on the slide rail 200. A pushing assembly 400 is installed on the top of the sliding assembly 300, and the top of the sliding assembly 300 rotates via a pin. Adjusting component 500 and pushing component 400 are used to release the rotation limit of adjusting component 500 and sliding component 300, so that the rotation of adjusting component 500 is convenient. The top of adjusting component 500 is equipped with auxiliary component 600 for material carrying. Adjusting component 500 is used to assist material adjustment into the inner cavity of machine tool body 100 for feeding. The two sides of auxiliary component 600 are equipped with clamping blocks 700 for assisting material clamping. By clamping the material with clamping blocks 700, it is convenient for CNC machining tools to perform CNC machining operations on the limited material.

[0061] The sliding assembly 300 includes a slider 301, a connecting block 302, a protective strip 303, a movable groove 304, and a slot 305. The slider 301 slides on the top of the slide rail 200. Two connecting blocks 302 are fixed to the two ends of the slider 301 respectively. The connecting blocks 302 are used for the adjustment component 500 to rotate through a pin. The protective strip 303 is fixed to the upper surface of the slider 301. The movable groove 304 is opened on the top of the slider 301. Multiple slots 305 are equidistantly opened at the bottom of the movable groove 304. The slots 305 are used to cooperate with the vertical limit of the adjustment component 500, so that the material can be turned and fed with the assistance of the adjustment component 500.

[0062] Furthermore, the pushing assembly 400 includes a pushing groove 401, a push plate 402, a tension spring 403, and a push rod 404. The pushing groove 401 is located on one side of the slider 301, and its inner cavity communicates with the inner cavities of multiple slots 305. The push plate 402 slides within the inner cavity of the pushing groove 401. One side of the top of the push plate 402 near the slot 305 has an upwardly inclined structure, so that when the push plate 402 slides into the inner cavity of the slot 305, it can push the structure on the adjusting member 500, allowing the structure on the adjusting member 500 to slide out of the inner cavity of the slot 305. This facilitates the rotation of the adjusting member 500 between the two connecting blocks 302. The push plate 402 is used to cooperate with the locking and unlocking of the adjusting member 500, allowing the adjusting member 500 to be moved to the outside of the inner cavity of the machine tool body 100, making it easier for materials to pass through the auxiliary assembly 600. The feeding is convenient, eliminating the need to insert the material into the inner cavity of the machine tool body 100 for adjustment, thus improving the convenience of material feeding. The tension spring 403 is fixed to one end of the push plate 402, and one end of the tension spring 403 is fixedly connected to the inner wall of the push plate 402. The push rod 404 is sleeved in the inner cavity of the tension spring 403, and one end of the push rod 404 is fixedly connected to one end of the push plate 402. The push rod 404 is slidably inserted into the outer wall of the slider 301. By pushing the push rod 404, the push rod 404 can move the push plate 402 in the inner cavity of the push groove 401. When there is no external force acting on the push rod 404, the tension spring 403 can pull the push plate 402 back to one side of the inner cavity of the push groove 401 through the stretching elasticity, so that it does not affect the connection between the structure on the adjustment part 500 and the slot 305.

[0063] Furthermore, the adjusting component 500 includes a rotating block 501, a positioning groove 502, a compression spring 503, a locking block 504, and a pushing strip 505. The side of the rotating block 501 is rotatably connected to the middle of the adjacent connecting block 302 via a pin, ensuring stable rotation of the rotating block 501. The bottom of the rotating block 501 rotates within the inner cavity of the movable groove 304. The protective strip 303 prevents the rotating block 501 from rotating towards the inner cavity of the machine tool body 100, facilitating easy loading of materials onto the auxiliary component 600. Multiple positioning grooves 502 are formed at the bottom of the rotating block 501. The compression spring 503 is fixed to the inner wall of the positioning groove 502, and the locking block 504 is fixed to the compression spring 501. At the bottom of the spring 503, the locking block 504 is slidably connected to the inner cavity of the positioning groove 502. Under the influence of gravity, the locking block 504 is slidably inserted into the inner cavity of the adjacent locking groove 305. Due to the elasticity of the compression spring 503, when the locking block 504 is opposite to the inner cavity of the locking groove 305, the locking block 504 can quickly slide into the inner cavity of the locking groove 305, which facilitates the rapid and stable positioning of the rotating block 501. The end of the push plate 402 near the locking block 504 is used to push the locking block 504 upward, so that the locking block 504 can be pushed out of the inner cavity of the locking groove 305 by the push plate 402, which facilitates the release of the position limitation of the rotating block 501, so that the locking block 504 can slide rubbing against the inner wall of the movable groove 304 and the inner wall of the protective strip 303.

[0064] Meanwhile, the push bar 505 is installed between the rotating block 501 and the auxiliary component 600. The push bar 505 is used for meshing and rotating relative to the two clamping blocks 700. The push bar 505 includes an electric telescopic rod 551 and a rack 552. The electric telescopic rod 551 is fixedly embedded in the top of the rotating block 501, and the rack 552 is fixed to the telescopic end of the electric telescopic rod 551. The rack 552 slides in the middle of the auxiliary component 600 and is synchronously meshed with the bottom of the two adjacent clamping blocks 700. The electric telescopic rod 551 is electrically connected to an external power source through an external switch. Driven by the electric telescopic rod 551, the rack 552 can telescopically move in the middle of the auxiliary component 600, so that the rack 552 can drive the clamping blocks 700 to perform clamping operations and stabilize the position of the material being fed.

[0065] In addition, the auxiliary component 600 includes a growth block 601, a mating groove 602, a limiting groove 603, and an arc-shaped groove 604. The growth block 601 is fixed to the top of the rotating block 501, and the rack 552 is slidably connected to the middle of the growth block 601. The mating groove 602 is opened through the middle and side of the growth block 601. Two clamping blocks 700 are respectively installed on both sides of the mating groove 602, so that the two clamping blocks 700 can perform clamping operations on the material carried in the middle of the growth block 601 from the top of the growth block 601. The limiting groove 603 is opened in the middle of the inner wall of the mating groove 602, and the arc-shaped groove 604 is opened in the middle of the upper surface of the growth block 601. Through the arc-shaped structure of the arc-shaped groove 604, it is convenient to support materials such as round rods at multiple points and improve the stability of material support.

[0066] More specifically, the clamping block 700 includes a rotating shaft 701, a gear 702, and a clamping rod 703. The end of the rotating shaft 701 is rotatably connected to the side of the inner wall of the mating groove 602 via a bearing. The gear 702 is fixed in the middle of the rotating shaft 701. The outer wall of the gear 702 has a multi-tooth block structure that mates with the outer wall of the rack 552. The clamping rod 703 is fixed to the outer wall of the gear 702 and is movably connected to the side of the mating groove 602. The two clamping rods 703 are used for clamping and limiting the processed material. The rack 552 is meshed with the outer walls of the two gears 702. The top of the rack 552 is movably connected to the inner cavity of the limiting groove 603. By moving the rack 552, the two gears 702 rotate in opposite directions, which makes it easier for the two gears 702 to stably clamp the material on the long block 601 and improve the stability of the material during processing on the machine tool.

[0067] Example 2: Based on Example 1, the inner cavity of the arc groove 604 has an arc-shaped structure with multiple rolling balls 800. The rolling balls 800 are used for rolling and repositioning of materials in a non-clamping state, which facilitates the convenient movement of heavy materials on the rolling balls 800. Moreover, the multiple rolling balls 800 can provide multi-point support for the materials.

[0068] A method for using a CNC machine tool auxiliary feeding device includes the following steps:

[0069] Step 1: Push the push rod 404 to stretch its tension spring 403. The push plate 402 moves toward the locking block 504, causing the locking block 504 to be pushed upward by the inclined surface of the push plate 402 and slide out of the inner cavity of the locking groove 305. At this time, the position of the rotating block 501 is not restricted.

[0070] Step 2: Move the rotating block 501 so that the locking block 504 moves in the inner cavity of the movable groove 304 toward the protective strip 303, and rotate the auxiliary component 600 on the rotating block 501 out of the inner cavity of the machine tool body 100, so that the material to be processed can be more easily loaded into the inner cavity of the limiting groove 603. The rolling of the ball 800 makes the loading and adjustment of the material convenient, and the drive of the electric telescopic rod 551 moves the rack 552, which drives the two clamping blocks 700 to clamp the material.

[0071] Step 3: Push the rotating block 501 in the opposite direction so that it stands vertically on the slider 301. The elongated block 601 moves back into the inner cavity of the machine tool body 100. At the same time, when the clamping block 504 rotates to the top of the clamping slot 305, it slides into the inner cavity of the clamping slot 305 under the influence of natural gravity and the elasticity of the compression spring 503, so that the rotating block 501 can maintain a vertical state and the material can be carried on the elongated block 601 for processing.

Through the rolling of the ball (800), the material loading adjustment is convenient, and through the drive of the electric telescopic rod (551), the rack (552) moves, driving the two clamping blocks (700) to clamp the material; Step 3: Push the rotating block (501) in the opposite direction so that the rotating block (501) can stand vertically on the slider (301) and the elongated block (601) moves back to the inner cavity of the machine tool body (100). At the same time, when the clamping block (504) rotates to the top of the clamping slot (305), it slides into the inner cavity of the clamping slot (305) under the influence of natural gravity and the elasticity of the compression spring (503), so that the rotating block (501) can maintain a vertical state and the material can be carried on the elongated block (601) for processing.
