Description

Technical Field

[0001] This invention relates to the field of machining technology, and in particular to a drilling device for machining and manufacturing. Background Technology

[0002] Machining is a manufacturing process that uses mechanical equipment to precisely alter the shape, size, accuracy, and surface quality of a workpiece. Its core technology is subtractive manufacturing, and it forms the foundation of modern manufacturing. Drilling is frequently required during machining processes.

[0003] When drilling holes in mechanical parts, it is generally necessary to fix the parts in place before drilling. In practical applications, some parts are irregularly shaped, and conventional general-purpose fixtures are difficult to hold stably. However, configuring a separate fixture for each product would greatly increase manufacturing costs.

[0004] For example, a drilling device for machining and manufacturing, disclosed in CN113814759A, uses multiple support rods supported by elastic elements to support parts. The elastic elements can adapt to the shape of the parts by extending and contracting, thus clamping irregular parts. However, the initial positions of the elastic elements and support rods are fixed. When clamping irregular parts, the compression state of the elastic elements at different positions will vary significantly, resulting in different reaction forces applied to the parts. This leads to inconsistent clamping effects at different positions of the parts, causing unbalanced forces on the parts, which may cause the parts to loosen during drilling, affecting the drilling quality. Another example is a drilling device for machining and manufacturing, disclosed in CN216065605U, which uses a U-shaped base and a pressure plate supported by a telescopic frame that can move with the drilling assembly to clamp parts. The telescopic frame extends and contracts according to the shape of the parts, providing adaptive clamping. However, similarly, the pressure applied by the pressure plate will vary depending on the shape of the parts, making it difficult to ensure force balance. The parts may still loosen during drilling, affecting the drilling quality. Summary of the Invention

[0005] This invention provides a drilling device for machining and manufacturing, which can solve the problem in the prior art that irregular mechanical parts are difficult to be stably clamped during the drilling process, and may loosen during the drilling process, affecting the drilling quality.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a drilling device for machining and manufacturing, comprising a base, a drilling assembly and a drilling drive component that can drive the drilling assembly to perform drilling actions are provided on the base, a processing table is provided on the processing table, at least two movable seats are provided on the processing table, and a control component that can drive the movable seats to move is also provided on the processing table; a mounting frame is fixedly connected to the movable seat, a mounting plate is movably connected inside the mounting frame, a spring is provided between the mounting plate and the mounting frame, a plurality of clamping rods are inserted into the mounting plate, and a locking component that can lock the position of the clamping rods is provided on one side of the mounting plate.

[0007] Preferably, the control component is a threaded rod rotatably connected to the lower part of the processing table, the movable seat is threadedly connected to the threaded rod, and one end of the threaded rod is fixedly connected to a lockable handwheel.

[0008] Preferably, the threaded rod is a bidirectional threaded rod, and there are two movable seats arranged symmetrically on the threaded rod.

[0009] Preferably, there are several springs, which are divided into upper and lower groups, respectively disposed at the top and bottom of the mounting plate.

[0010] Preferably, a plurality of guide rods are fixedly connected inside the mounting frame, and the mounting plate is sleeved on the guide rods.

[0011] Preferably, the number of guide rods is the same as the number of springs, and the springs are sleeved on the outside of the guide rods.

[0012] Preferably, the locking assembly includes a drive rod rotatably connected within the mounting plate, a rotary drive component capable of rotating the drive rod, a slider threadedly connected to the drive rod, a locking plate fixedly connected to the slider, and a locking head fixedly connected to the locking plate.

[0013] Preferably, there are two drive rods, an upper one and a lower one, and a synchronous transmission assembly including a transmission chain and a transmission wheel is provided between the two drive rods to enable the two drive rods to rotate synchronously.

[0014] Compared to existing technologies, this invention, through the inclusion of a movable base, control components, a mounting frame, a mounting plate, springs, clamping rods, and a locking component, allows for efficient drilling. During drilling, the mechanical part to be drilled is placed on the processing table. The control components move the movable base towards the mechanical part, which in turn moves the mounting frame and clamping rods. Once the clamping rods are against the mechanical part, they adapt to its shape and move relative to the mounting plate. The locking component then locks the clamping rods in place. The control components continue to move the movable base towards the mechanical part, at which point the springs begin to compress. Their elastic force is transmitted through the mounting plate to the clamping rods, clamping the mechanical part. The initial positions of the multiple clamping rods can be adaptively adjusted according to the shape of the mechanical part. During clamping, all springs deform uniformly, ensuring balanced forces on the mechanical part and greater stability during drilling, thus guaranteeing drilling quality. Attached Figure Description

[0017] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the technical solution of this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0018] like Figures 1 to 3 As shown, the present invention provides a drilling device for machining and manufacturing, including a base 1, a drilling assembly 3 and a drilling drive 2 that can drive the drilling assembly 3 to perform drilling operations on the base 1, a processing table 4 on the processing table 4, at least two movable seats 5 on the processing table 4, and a control component 6 that can drive the movable seats 5 to move on the processing table 4; a mounting frame 7 is fixedly connected to the movable seat 5, a mounting plate 8 is movably connected inside the mounting frame 7, a spring 9 is provided between the mounting plate 8 and the mounting frame 7, a plurality of clamping rods 10 are inserted into the mounting plate 8, and a locking component 11 that can lock the position of the clamping rods 10 is provided on one side of the mounting plate 8.

[0019] Specifically, base 1 provides an installation platform for the upper structure. Base 1 should have sufficient weight to ensure the overall stability of the device and is generally made of cast iron. Drilling drive 2 drives the drilling assembly 3 to rotate, performing the drilling action. Drilling drive 2 is generally a motor, which transmits power through a belt and a transmission mechanism to drive the drilling assembly 3 to rotate. Machining table 4 provides a platform for placing the machine parts to be processed. The above structures are all publicly available in the prior art. For details, please refer to the bench drill. The drilling assembly 3 and drilling drive 2 form the machine head, which is mounted on base 1 via a column. The drilling assembly 3 mainly includes a spindle, drill chuck, feed handle, etc. Machining table 4 can be raised, lowered, and tilted (generally 0-90°), and has a through hole for chip removal. In addition, a locking handle is generally provided to fix the column height, worktable angle, and machine head position. Adjustment component 6, in conjunction with moving base 5, drives mounting frame 7 to move horizontally, so that the clamping structure on mounting frame 7 can clamp the machine parts to be processed. The control component 6 can be a structure or component that can be operated manually or electrically, such as a threaded rod or an electric push rod.

[0020] The mounting frame 7 provides installation and movement space for the mounting plate 8, and also provides constraints to prevent displacement in other directions. A spring 9 is installed between the mounting frame 7 and the mounting plate 8 to provide elastic support for the mounting plate 8. The elasticity of the spring 9 allows the clamping rod 10 to provide flexible support for the mechanical parts, avoiding damage to the mechanical parts from rigid support. The clamping rod 10 is used to directly contact and clamp the mechanical parts. Several clamping rods 10 support the mechanical parts from different positions, allowing irregular mechanical parts to obtain multi-point support and improving the clamping effect. It should be noted that anti-detachment heads are preferably provided at both ends of the clamping rod 10 to prevent the clamping rod 10 from completely detaching from the mounting plate 8. A flexible clamping head, such as a rubber head, can be provided at the inner end of the clamping rod 10 to transform its contact with the mechanical parts into a flexible contact, preventing damage to the mechanical parts from support. The clamping rod 10 is preferably rectangular to facilitate contact and locking of the locking component 11. The locking component 11 can adopt a structure of threaded rod with moving block and locking block, or an electric push rod with moving block and locking block. The locking component 11 is preferably located on the front of the mounting plate 10 for easy operation by staff.

[0021] In practical use, the mechanical part to be drilled is placed on the processing table 4. The control component 6 drives the moving seat 5 to move towards the mechanical part. The moving seat 5 drives the mounting frame 7 and clamping rod 10 to move. After the clamping rod 10 comes into contact with the mechanical part, it adapts to the shape of the mechanical part and moves relative to the mounting plate 8. The locking component 11 locks the clamping rod 10. The control component 6 continues to drive the moving seat 5 towards the mechanical part. At this time, the spring 9 begins to be compressed, and its elastic force is transmitted to the clamping rod 10 through the mounting plate 8 to clamp the mechanical part. Then, the drilling drive component 2 can be activated to drive the drilling assembly 3 to rotate and drill the mechanical part. After drilling is completed, the control component 6 drives the moving seat 5 to move in the opposite direction, causing the clamping rod 10 to disengage from the side of the mechanical part. Then, the drilled mechanical part can be removed.

[0022] like Figures 2 to 3 As shown, in order to achieve convenient and precise adjustment of the position of the movable seat, preferably, the control component 6 adopts a threaded rod rotatably connected to the lower part of the processing table 4, the movable seat 5 is threadedly connected to the threaded rod, and one end of the threaded rod is fixedly connected to a lockable handwheel 12.

[0023] Specifically, rotating the handwheel 12 drives the threaded rod to rotate, and under the constraint of the machining table 4, the thread on the threaded rod drives the moving seat 5 to move horizontally. Manually rotating the handwheel 12 drives the moving seat 5 to move via the threaded rod, and the movement distance of the moving seat 5 can be precisely controlled. The handwheel 12 can be locked by creating a locking groove on the machining table 4 and using a locking bolt. Locking the handwheel 12 prevents the threaded rod from rotating in the opposite direction, ensuring that the mounting frame 7, mounting plate 8, and clamping rod 10 provide stable clamping for the mechanical parts.

[0024] The threaded rod is installed below the machining table 4, providing sufficient space above the machining table 4 for placing the mechanical parts to be processed. At this point, a sliding groove can be created on the machining table 4, and the movable seat 5 can be placed within the groove to connect the movable seat 5 to the mounting frame 7 on the machining table 4. Simultaneously, the sliding groove also constrains the movable seat 5, preventing it from rotating along with the threaded rod.

[0025] like Figures 2 to 3 As shown, in order to centrally clamp the mechanical parts on the processing table, preferably, the threaded rod is a bidirectional threaded rod, and there are two movable seats 5 arranged symmetrically on the threaded rod.

[0026] Specifically, a bidirectional threaded rod (positive and negative threads / left and right threaded rod) is a transmission component that simultaneously processes left-hand and right-hand threads on the same threaded rod. Its core function is to drive two moving seats 5 to move synchronously in opposite directions (towards / backwards) in a linear motion through the single-axis rotation of the threaded rod. The two moving seats 5 are symmetrically arranged on the threaded rod, enabling them to move symmetrically and synchronously, allowing the mechanical parts to be centrally clamped on the machining table 4, and enabling the mechanical parts to be drilled in the center.

[0027] like Figures 4 to 6 As shown, in order to achieve stable horizontal movement of the mounting plate and provide stable clamping for the mechanical parts, preferably, there are several springs 9, which are divided into upper and lower groups and respectively set at the top and bottom of the mounting plate 8.

[0028] Specifically, several springs 9 provide elastic support to the mounting plate 8 from different positions. The springs 9 are divided into upper and lower groups, which balances the forces on the upper and lower ends of the mounting plate 8, facilitating stable horizontal movement of the mounting plate. On this basis, the mounting plate 8 also provides the same support conditions for multiple clamping rods 10, enabling the clamping rods 10 to provide stable clamping for mechanical parts.

[0029] like Figures 4 to 6 As shown, in order to further improve the stability of the mounting plate when it moves, preferably, a number of guide rods 13 are fixedly connected inside the mounting frame 7, and the mounting plate 8 is sleeved on the guide rods 13.

[0030] Specifically, a guide rod 13 is installed within the mounting frame 7. The guide rod 13 constrains the mounting plate 8, preventing it from shifting in other directions. Based on the function of the guide rod 13, it is clear that it should possess sufficient rigidity to ensure it does not bend or deform under the action of the mounting plate 8. 45# steel or 40Cr is preferred. 45# steel offers sufficient strength, good rigidity, and is not easily bent, while also being inexpensive and easy to process. 40Cr is the preferred material for high-strength guide rods, with strength, toughness, and bending resistance far superior to 45# steel. After tempering, its overall performance is very stable, making it suitable for heavy-duty guide rods, long guide rods, and high-stress sliding tables, and is the most commonly used high-strength guide rod material in industrial equipment. Alternatively, 304 stainless steel can also be used, which has moderate strength, is rust-resistant, and suitable for light-load guidance; 316 stainless steel is more corrosion-resistant and has slightly higher strength than 304 stainless steel. The guide rod 13 is preferably a cylindrical member, with smooth sides, allowing the mounting plate 8 to slide smoothly on it.

[0031] like Figures 4 to 6 As shown, in order to achieve the purpose of the spring providing stable elastic support for the mounting plate, preferably, the number of guide rods 13 is the same as the number of springs 9, and the springs 9 are sleeved on the outside of the guide rods 13.

[0032] Specifically, the number of guide rods 13 is consistent with the number of springs 9, and the springs 9 are sleeved on the outside of the guide rods 13. While constraining and guiding the mounting plate 8, the guide rods 13 also provide constraint for the springs 9, which can prevent the springs 9 from bending, tilting upwards, downwards, or tilting to both sides under the pressure of the mounting plate 8. This ensures that the springs 9 can only perform extension and retraction along the length of the guide rods 13, thereby enabling the springs 9 to provide stable elastic support for the mounting plate.

[0033] like Figure 7 As shown, in order to quickly lock all clamping rods, the locking assembly 11 preferably includes a drive rod 1101 rotatably connected in the mounting plate 8, a rotary drive 1102 that can drive the drive rod 1101 to rotate, a slider 1103 threadedly connected to the drive rod 1101, a locking plate 1104 fixedly connected to the slider 1103, and a locking head 1105 fixedly connected to the locking plate 1104.

[0034] Specifically, the rotary drive component 1102 drives the drive rod 1101 to rotate. Under the constraint of the mounting plate 8, the drive rod 1101 drives the slider 1103 to move. The slider 1103 drives the locking plate 1104 and the locking head 1105 to move. The locking head 1105 moves and contacts the clamping rod 10, and under the push of the locking plate 1104, it presses against the clamping rod 10, thereby locking the clamping rod 10. Several locking heads 1105 follow the locking plate 1104 to lock multiple clamping rods 10. The rotary drive component 1102 can be a micro motor, a manual turntable, etc. It should be noted that when using a micro motor, the motor should have a locking function to prevent the shaft from reversing. When using a manual turntable, the manual turntable should also have a locking structure to prevent the drive rod 1101 from reversing, so as to ensure that the clamping rod 10 will not be unlocked under external force after being locked. The locking structure can be achieved by opening a locking groove on the mounting plate 8 and using a locking bolt.

[0035] like Figure 7 As shown, in order to achieve the purpose of simultaneously and securely locking multiple clamping rods, preferably, the drive rod 1101 has two rods, upper and lower, and a synchronous transmission assembly including a transmission chain and a transmission wheel is provided between the two drive rods 1101 to enable the two drive rods 1101 to rotate synchronously.

[0036] Specifically, the two drive shafts 1101 synchronously drive the locking plate 1104 to move horizontally from the upper and lower ends. This makes the movement of the locking plate 1104 more stable and provides roughly equal support force to the locking heads 1105 at different positions, enabling them to provide a comparable locking effect. As can be seen from the above usage method, the locking effect of the locking heads 1105 at different positions is directly related to the strength of the locking plate 1104. Therefore, the locking plate 1104 should have sufficient strength, preferably made of 45# steel or 40Cr material.

[0037] Compared to existing technologies, this invention, through the arrangement of a movable base 5, a control component 6, a mounting frame, a mounting plate 8, springs 9, clamping rods 10, and a locking component 11, allows for efficient drilling. During drilling, the mechanical part to be drilled is placed on the processing table 4. The control component 6 moves the movable base 5 towards the mechanical part, which in turn moves the mounting frame 7 and clamping rods 10. After the clamping rods 10 come into contact with the mechanical part, they adapt to the shape of the part and move relative to the mounting plate 8. The locking component 11 then locks the clamping rods 10 in place. The control component 6 continues to move the movable base 5 towards the mechanical part. At this point, the springs 9 begin to compress, and their elastic force is transmitted through the mounting plate 8 to the clamping rods 10, clamping the mechanical part. The initial positions of the multiple clamping rods 10 can be adaptively adjusted according to the shape of the mechanical part. During clamping, all springs 9 deform identically, ensuring balanced forces on the mechanical part and greater stability during drilling, thus improving drilling quality.

[0038] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
