Description

Technical Field

[0001] This invention relates to the technical field of mold processing, specifically to an auxiliary drilling device for processing mold parts. Background Technology

[0002] In the field of mold manufacturing and repair, drilling various mold components (such as mold cores, sliders, inserts, etc.) is a common and crucial process. Existing auxiliary drilling equipment for mold component processing typically refers to a clamping device on a general-purpose drilling machine or a dedicated drilling machine, used to fix the workpiece. The standard procedure is as follows: the operator first places the mold component on the machine tool's worktable, clamps and fixes it from both sides or top and bottom using a vise, clamping plate, or special chuck, then adjusts the position of the machine tool spindle or worktable to align the drill bit with the preset machining hole position, and finally starts the equipment to complete the drilling. The core structure of this type of equipment mainly includes the spindle and drill bit that provide cutting power, the worktable that supports the workpiece, and the clamping device that holds the workpiece. Its core function is to provide a stable reference for drill bit processing, resisting the cutting forces and vibrations generated during drilling through rigid clamping, ensuring the positional accuracy of the hole. However, the clamps equipped on this type of equipment are mostly general-purpose clamps designed for workpieces with regular shapes.

[0003] Existing clamping devices, whether simple flat-jaw vises or complex combination clamping plates, are designed to provide sufficient lateral or vertical clamping force to prevent workpiece movement. However, the inherent shortcomings of such clamping devices become apparent when dealing with irregularly shaped mold parts with irregular bottom surfaces, complex curves, or poor rigidity. First, the clamping surface of the clamp often cannot fully conform to the irregular side or bottom surface of the workpiece. To meet clamping requirements, excessive force is often required, easily leading to deformation or damage to thin-walled or precision-machined workpieces. Second, traditional clamping devices lack effective adaptive support for the bottom of the workpiece, which is often suspended or only supported by a few rigid points. Under the axial force of drilling, this can easily cause micro-chatter or bending, affecting the straightness of the hole and the quality of the inner wall. Furthermore, for irregularly shaped parts requiring adjustment of machining angles, it is difficult for the operator to conveniently and accurately fine-tune the workpiece's posture while it is clamped. Therefore, to solve the above-mentioned problems, an auxiliary drilling device for mold part processing is provided. Summary of the Invention

[0004] The purpose of this invention is to provide an auxiliary drilling device for processing mold parts, in order to solve the problems mentioned in the background art of existing auxiliary devices for drilling mold parts, which lack effective bottom adaptive support and attitude fine adjustment capabilities when clamping irregularly shaped or irregularly shaped workpieces, resulting in unstable clamping, easy deformation of workpieces, difficulty in guaranteeing processing accuracy, and cumbersome operation and low efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an auxiliary drilling device for processing mold parts, including a machine tool, a drill bit for drilling is provided at the upper end of the machine tool, a slide groove is provided on the worktable of the machine tool and the slide groove is located directly below the drill bit, and a clamp is slidably installed in the slide groove, the clamp being used to clamp the mold parts from both sides;

[0006] The fixture is equipped with multiple support components that can independently extend and retract vertically. These support components are used to adaptively contact and support the irregular lower surface of the mold parts, thereby forming a multi-angle, multi-point composite positioning and fixation of the irregular mold parts together with the fixture.

[0007] In a further embodiment, the fixture includes a fixed table, a sliding table, and a lead screw. One end of the fixed table is connected to a slide rail. The fixed table and the slide rail are slidably installed in the slide groove of the machine tool. The sliding table is slidably installed in the slide rail. The two ends of the lead screw are rotatably connected to the end face of the fixed table and one end of the slide rail, respectively. The sliding table is threadedly connected to the lead screw.

[0008] In a further embodiment, the support includes a sleeve, a support rod, and a spring. The sleeve is located between the fixed platform and the sliding platform. The support rod is slidably inserted into the upper end of the sleeve. The spring is installed inside the sleeve and is used to apply an upward elastic force to the support rod.

[0009] In a further embodiment, the upper end of the support rod is configured as a ball, and a connector is rotatably engaged at the ball at the upper end of the support rod, with a contact threadedly connected to the upper end of the connector.

[0010] In a further embodiment, a linkage mechanism is provided inside the fixture, which is used to link the sliding table and the support.

[0011] In a further embodiment, four support members are provided, and the linkage mechanism includes a connecting frame, a connecting pipe and a hinge support. Multiple hinge supports are fixedly connected to the fixed platform and the sliding platform respectively. The connecting frame is composed of two rods that are rotatably connected at one end, and the rotatable connection of the two rods is rotatably mounted on the hinge support. The other end of the rod is rotatably sleeved on the sleeve.

[0012] The connecting pipe consists of two pipe bodies connected at their middle ends by a pin, and both ends of the pipe bodies are fixedly connected to the outer wall of the sleeve.

[0013] In a further embodiment, the connecting pipe is provided with a fixing mechanism for fixing the length of the support rod extending from the upper end of the sleeve.

[0014] In a further embodiment, the fixing mechanism includes a locking block, a conduit, and a cylinder. The locking block is sealed and slides at one end of the connecting pipe, and one end of the locking block can extend into the sleeve to contact the outer wall of the support rod. The cylinder is fixedly installed in the sliding table. One end of the conduit is connected to the outer wall of the connecting pipe, and the other end extends into the sliding table to connect with one end of the cylinder.

[0015] In a further embodiment, a piston is slidably mounted inside the cylinder, and a screw is rotatably connected to one end of the piston. The screw is threadedly connected to one end of the cylinder, and one end of the screw extends out from the end face of the sliding table.

[0016] In a further embodiment, one end of the lead screw and one end of the screw are provided with a drive component for easy control of rotation, and the upper end of the slide rail is connected with a handle for easy control of the slide rail sliding.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This invention is an auxiliary drilling device for processing mold parts. By setting up a sliding fit between the fixture and the machine tool slide groove and a composite positioning structure of bottom support and lateral clamping, it solves the problem that traditional fixtures cannot quickly position, finely adjust the posture and stably fix irregular workpieces in the clamping state, resulting in low clamping efficiency and narrow application range.

[0019] 2. By installing multiple independently extendable support components inside the fixture, the problems of workpiece deformation, large processing vibration, and poor hole accuracy caused by the bottom being suspended or improperly supported when clamping irregular mold parts are solved.

Detailed Implementation

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below. 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.

[0037] Please see Figures 1-15 This embodiment provides an auxiliary drilling device for processing mold parts, including a machine tool 1. A drill bit for drilling is installed at the upper part of the machine tool 1. A slide groove is provided on the worktable of the machine tool 1, and a fixture 2 is slidably mounted within the slide groove. This slide groove is located directly below the drill bit to ensure that the workpiece is aligned with the drill bit axis after being positioned on the fixture 2. Through the sliding engagement of the slide groove and the fixture 2, the operator can flexibly adjust the position of the fixture 2 and the workpiece on the worktable of the machine tool 1 according to the size of the mold part and the drilling position requirements, achieving rapid tool setting and positioning. This design eliminates the tediousness of repeatedly adjusting large workpieces and improves processing preparation efficiency.

[0038] The fixture 2 is the core positioning and clamping module of this invention, mainly used for performing lateral clamping functions, and also integrates a bottom adaptive support system. The fixture 2 includes a fixed platform 21, a sliding platform 22, and a lead screw 23. The fixed platform 21 serves as the reference part of the fixture 2, with a slide rail 211 fixedly connected to one end. The fixed platform 21 and the connected slide rail 211 are slidably mounted together in the slide groove of the machine tool 1, realizing the overall movement of the fixture 2 on the machine tool 1. The sliding platform 22 is slidably mounted on the slide rail 211 and can move linearly relative to the fixed platform 21 under the guidance of the slide rail 211. The two ends of the lead screw 23 are rotatably connected to the end face of the fixed platform 21 and the far end of the slide rail 211, respectively. The sliding platform 22 is threadedly connected to the lead screw 23 through its internal threaded hole. When the operator rotates the lead screw 23, the sliding table 22 moves along the slide rail 211 towards or away from the fixed table 21, thereby clamping or releasing the mold parts placed between the fixed table 21 and the sliding table 22. One end of the lead screw 23 is equipped with a drive component for easy rotation control, such as... Figure 5 As shown, the driving component of the connecting screw 23 is a handwheel structure. Of course, the driving component is not limited to a handwheel; it can also be other structures that facilitate the application of force. This screw 23 driving method provides a stable and precisely controllable clamping force and has a self-locking characteristic, which can reliably prevent the workpiece from loosening due to vibration during processing.

[0039] like Figure 2 and Figure 3As shown, the upper end of the slide rail 211 is connected to a handle for easy control of its sliding, facilitating the operator's movement of the entire fixture 2. Particularly advantageous is the design of both the slide rail 211 and the grooves on the machine tool 1 as openwork structures. Metal shavings generated during drilling can fall directly through these openings, effectively preventing shavings from accumulating in the slide rail 211 or the grooves. This anti-accumulation design fundamentally solves the problem of shavings jamming and affecting the smooth movement of the sliding table 22 within the slide rail 211, or affecting the sliding of the fixed table 21 and the slide rail 211 as a whole within the grooves of the machine tool 1, ensuring the long-term reliability of the equipment and reducing maintenance requirements.

[0040] Between the fixed platform 21 and the sliding platform 22 of the fixture 2, multiple support members 3 are provided, each capable of independent vertical telescopic movement. These support members 3 adaptively contact and support the irregular lower surface of the mold component, thus, together with the fixture 2 which performs lateral clamping, forming a multi-angle, multi-point composite positioning and fixation system for the irregularly shaped mold component. Each support member 3 includes a sleeve 31, a support rod 32, and a spring 33. The sleeve 31 is fixedly installed at the corresponding position on the fixed platform 21 or the sliding platform 22, located in the working area between them. The support rod 32 is slidably inserted into the upper opening of the sleeve 31 and can extend and retract axially along the sleeve 31. The spring 33 is installed inside the sleeve 31, and its natural elasticity continuously acts on the support rod 32, applying an upward thrust to the support rod 32. When the mold components are placed between the fixed table 21 and the sliding table 22, and their lower surfaces contact the tops of the support rods 32, due to the weight and irregular shape of the workpiece, each support rod 32 will experience different degrees of downward pressure, thereby compressing its corresponding spring 33 and producing different contraction displacements. This process is completely adaptive; the tops of multiple support components 3 together form a support surface that matches the irregular lower surface contour of the workpiece, providing stable, close, and uniform bottom support for the workpiece. This support method greatly reduces the risk of deformation of large overhanging or thin-walled irregularly shaped workpieces due to bottom suspension or only a few points of support, providing a crucial foundation for subsequent high-precision drilling.

[0041] To optimize the contact between the top of the support rod 32 and the workpiece surface, the upper end of the support rod 32 is designed as a spherical structure. A connector 321 with a bowl-shaped lower end rotates and engages with the sphere at the upper end of the support rod 32, forming a ball-and-socket connection. This design allows the connector 321 to swing at multiple angles relative to the support rod 32, ensuring that the upper surface of the connector 321 can better adapt to the local tilt angles of different areas on the lower surface of the workpiece, optimizing the contact from point contact to small-area contact, improving the stability of the support, and reducing stress concentration. The upper end of the connector 321 is connected to a contact 322 via a thread. As the component that directly contacts the workpiece, the contact 322 can be replaced according to the specific conditions of the processed parts (such as material hardness and surface finish requirements). Different styles, types, and materials of contact 322 can be adapted. For example, for a pre-machined surface, a soft material contact 322 can be used to prevent scratches. For a rough surface requiring greater friction, a textured hard contact 322 can be used. This modular design significantly enhances the versatility and process adaptability of support component 3.

[0042] To ensure that multiple support members 3 can move collaboratively and remain below the working area when the sliding table 22 moves, a linkage mechanism 5 is provided inside the clamp 2. In this embodiment, four support members 3 are preferably arranged near the four corners of the working area. The linkage mechanism 5 includes a connecting frame 51, a connecting pipe 52, and hinge supports 53. Multiple hinge supports 53 are fixedly connected to the fixed table 21 and the sliding table 22, respectively. Each connecting frame 51 consists of two rods, such as... Figure 5 , Figure 8 and Figure 11As shown, one end of each of the two rods is rotatably connected to form a V-shaped structure, and this rotatable connection is rotatably mounted on the corresponding hinge support 53 via a pivot. The other end of each rod is rotatably sleeved on the outer wall of the sleeve 31 of the corresponding support member 3. The connecting tube 52 consists of two tubes, the middle ends of which are rotatably connected together by a pin, and the two ends of the tubes are respectively fixedly connected to the outer walls of two adjacent sleeves 31. Specifically, the part of the connecting tube 52 rotatably connected by the pin in the middle forms an annular tube, while the parts connected to the sleeves 31 at both ends are square tubes. This structure makes the two connecting tubes 52 connected by the pin form an X-shaped scissor linkage structure. When the operator rotates the screw 23 to drive the sliding table 22 to move, the position of the sliding table 22 relative to the fixed table 21 changes. This movement is transmitted to the sleeves 31 through the hinge support 53 and the connecting frame 51. At the same time, the scissor linkage structure composed of the connecting tubes 52 transforms the movement of the sliding table 22 into a coordinated change in the relative distance between the four sleeves 31. As a result, regardless of the position of the sliding table 22 (clamped or unclamped), the four support members 3 can move synchronously under the drive of the linkage mechanism 5, always evenly distributed below the working area defined by the fixed table 21 and the sliding table 22. This means that throughout the entire process of the fixture 2 clamping accessories of different widths, the support members 3 can always effectively support the lower end of the accessories, providing continuous and stable adaptive bottom support. There is no need for manual readjustment of the support position, resulting in a high degree of automation and extremely simple operation.

[0043] The workflow of fixture 2 has significant ergonomic advantages. After the operator initially places the irregularly shaped mold component to be processed between the fixed table 21 and the sliding table 22, the component is in a relatively stable but finely adjustable state due to the support rod 32 supported by multiple springs 33 at the bottom. At this time, the operator can easily adjust the angle and posture of the component in space by applying slight pressure or upward pulling force. This fine-tuning capability is crucial for mold component processing because it allows the operator to precisely adjust the drilling position of the component, including the inlet point of the upper drill bit and the possible outlet point of the lower end, ensuring that the drilling path meets the design requirements and avoiding hole position deviation or one-sided cutting of the drill bit due to improper workpiece placement. After determining the final posture and position of the workpiece, rigid fixation is required.

[0044] The accessory can easily move up and down between the fixed platform 21 and the sliding platform 22 when held by clamp 2 alone. Therefore, to further secure the accessory, a fixing mechanism 6 is provided on the connecting pipe 52. The fixing mechanism 6 is used to fix the length of each support rod 32 extending from the upper end of the sleeve 31, that is, to lock the adaptive support state into a rigid support state. The fixing mechanism 6 includes a locking block 61, a guide tube 62, and a cylinder 63. The locking block 61 is slidably installed inside one end of the connecting pipe 52, and one end of the locking block 61 can extend into the sleeve 31 and contact the outer wall of the support rod 32. The cylinder 63 is fixedly installed inside the sliding platform 22. One end of the guide tube 62 is connected to the outer wall of the connecting pipe 52 and communicates with the inner cavity of the connecting pipe 52, while the other end extends into the sliding platform 22 and connects to one end chamber of the cylinder 63. A piston 631 is slidably installed inside the cylinder 63, and the piston 631 divides the interior of the cylinder 63. One end of the piston 631 is rotatably connected to a screw 632, which is threadedly connected to one end of the cylinder 63, and one end of the screw 632 extends from the end face of the sliding table 22. One end of the screw 632 is provided with a drive component for convenient rotation control, such as a knob with a screw-like structure, but the drive component is not limited to the above structure.

[0045] During operation, the operator rotates the screw 632 via a drive mechanism. The rotational motion of the screw 632 is converted into the linear movement of the piston 631 within the cylinder 63 via a threaded joint. The movement of the piston 631 compresses or draws the gas (usually air) within the cylinder 63 chamber, and the gas pressure is transmitted through the conduit 62 to the closed cavity of the connecting pipe 52. Since all connecting pipes 52 are interconnected through the piping design, changes in air pressure will act synchronously on all locking blocks 61. When locking is required, the movement of the piston 631 compresses the gas within the cylinder 63. The pressurized gas enters the connecting pipe 52 through the conduit 62, pushing each locking block 61 into the sleeve 31. After the locking block 61 extends into the sleeve 31, its end presses against the outer wall of the support rod 32 with sufficient pressure, and the frictional force firmly fixes the support rod 32 in its current position, preventing it from sliding relative to the sleeve 31. In this way, the lengths of all support rods 32 extending from the sleeve 31 are fixed simultaneously and all at once, and the bottom support changes from a "flexible adaptive" state to a "rigid holding" state. Subsequently, the drive component at the end of the lead screw 23 is tightened to clamp the sides of the workpiece with the sliding table 22, ultimately completing the complete constraint of the workpiece in six degrees of freedom in three-dimensional space. The separate design of the fixing mechanism 6 and the clamping action enforces the correct process flow of "first positioning and locking the bottom support, then clamping laterally," effectively preventing workpiece deformation or bottom suspension that may occur if clamping is done first, and ensuring positioning accuracy.

[0046] Compared to existing mold component drilling equipment or general-purpose fixtures, this invention adopts a purely mechanical structure, innovatively integrating a sliding fixture 2, a bottom multi-point, multi-degree-of-freedom adaptive elastic support mechanism, a support state linkage locking mechanism, and a lateral clamping mechanism. This invention solves the industry problems of unstable clamping, easy deformation, poor positioning accuracy, and cumbersome adjustments when drilling irregularly shaped or irregularly shaped mold components. Through bottom adaptive support and a lockable design, combined with lateral clamping, it achieves rapid, accurate, and non-destructive composite positioning and rigid fixation of complex workpieces. The unique hollow slide rail 211, the chip-proof design of the slide groove, and the linkage support mechanism further enhance the reliability, ease of operation, and automation of the equipment, making it particularly suitable for precision drilling of mold components in small batches and with a wide variety of products.
