Description

Technical Field

[0001] This utility model relates to the technical field of coupling processing equipment, and in particular to a drilling device for coupling processing. Background Technology

[0002] Couplings, as a widely used standard mechanical transmission component, often require secondary machining processes such as drilling or tapping during their manufacturing to install connecting bolts or keys. These machining tasks are typically completed on machine tools such as drilling machines or machining centers.

[0003] Under the existing processing model, operators typically use a single-piece flow method. This involves manually placing and clamping the coupling workpiece on the worktable, starting the equipment to complete the drilling, removing the processed workpiece, and then placing the workpiece to be processed. In this processing method, the equipment is idle and waiting during the workpiece loading, unloading, and positioning stages, causing interruptions in the processing cycle and resulting in relatively low overall production efficiency, especially during batch production.

[0004] Furthermore, to improve efficiency, heavier multi-axis drilling heads or specialized drilling tools are sometimes used. However, these machines are large in size and weight, making their installation, disassembly, or repositioning on machine tools extremely cumbersome. This often requires multiple workers to operate simultaneously, consuming significant manpower and time. Moreover, during handling and alignment, there is a risk of equipment slipping or colliding due to improper operation, posing safety hazards to both personnel and equipment. This inconvenient installation and maintenance process further reduces the efficiency of production preparation and equipment adjustment.

[0005] Therefore, this utility model proposes a drilling device for coupling processing to overcome the shortcomings of the prior art. Summary of the Invention

[0006] In view of the problems of low processing efficiency, inability to operate continuously, cumbersome and time-consuming installation process, and safety hazards of existing coupling processing drilling devices, this utility model aims to provide a drilling device for coupling processing with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a drilling device for coupling processing, including a machine tool, a frame and a placement slot; as well as a linkage mechanism and an installation mechanism.

[0008] The linkage mechanism includes a slide groove on the machine tool, gear teeth fixedly connected in the slide groove, and a slider slidably connected in the slide groove. The frame is fixedly connected to the upper surface of the slider, a motor is fixedly connected to the slider, and a circular block is fixedly connected to the output end of the motor. The outer periphery of the circular block has a tooth groove that meshes with the gear teeth for transmission.

[0009] The installation mechanism includes an installation slot and an installation block located at the lower end of the frame. A hydraulic telescopic rod is installed inside the installation block. A push plate is fixedly connected to the output end of the hydraulic telescopic rod. A locking rod is rotatably connected to the installation block. The push plate and the locking rod are connected by a transmission mechanism through a rotating component one and a rotating component two.

[0010] Furthermore, the slider of the linkage mechanism moves with the slide groove of the machine tool through a sliding fit, and the tooth groove of the circular block and the gear teeth in the slide groove convert the rotational motion of the motor into linear motion through meshing transmission; the mounting block of the mounting mechanism is combined with the mounting groove of the frame through a pluggable fit, and the hydraulic telescopic rod drives the locking rod to rotate through the push plate, rotating component one and rotating component two, so as to realize the locking or separation of the far end of the locking rod from the inner wall of the mounting groove.

[0011] Preferably, the linkage mechanism further includes a cleaning component, which includes a first transmission wheel fixedly connected to the circular block, a second transmission wheel connected to the first transmission wheel via a belt, and a soft brush fixedly connected to the second transmission wheel. The bristles of the soft brush can abut against the inner bottom surface of the slide groove, thereby cleaning the track synchronously during movement and ensuring smooth operation.

[0012] Preferably, the second transmission wheel is rotatably connected to the slider via a fixed rod, and the transmission wheel is coaxially fixed to the side of the round block near the motor. This layout is compact and can effectively utilize the power of the main drive motor to achieve synchronous operation of the sweeping function without the need for an additional power source, thus saving costs and space.

[0013] Preferably, the mounting groove is designed as a tapered structure that is narrow on the outside and wide on the inside. This geometry provides a structural basis for the wedge-type clamping of the clamping rod. At the same time, a flange is fixedly connected to the outer wall of the mounting block. Both the flange and the frame are provided with threaded holes through which bolts can pass and lock. The bolt connection provides the final, high-strength rigid fixation of the equipment, ensuring absolute stability during the processing.

[0014] Preferably, the first end of the rotating component one is rotatably connected to the push plate, and the second end is rotatably connected to the middle of the locking rod; the first end of the rotating component two is rotatably connected to the locking rod, and the second end is rotatably connected to the inner wall of the mounting block, thus clarifying the precise connection points of each link and ensuring the accuracy of motion transmission.

[0015] Preferably, the slider has a first position slot, i.e., position slot one, for accommodating and fixing the motor, which provides a precise reference for the installation of the motor, ensures the coaxiality of the motor and the circular block, and is beneficial to the transmission efficiency.

[0016] Preferably, the mounting block has a second position slot, i.e., position slot two, for accommodating and installing the hydraulic telescopic rod, which also provides a standardized positioning for the installation of the hydraulic telescopic rod, facilitating assembly and maintenance.

[0017] Preferably, the locking rod is integrally formed or fixedly connected between rotating component one and rotating component two, and extends outward to form a locking section that can engage with the inner wall of the mounting groove. This structure simplifies the number of parts and enhances the overall rigidity of the locking rod.

[0018] Preferably, the telescopic axis of the hydraulic telescopic rod is perpendicular to the direction of movement of the slider. This spatial layout ensures that the action of the installation mechanism and the movement of the linkage mechanism do not interfere with each other in space, resulting in a reasonable structural layout.

[0019] Preferably, the connection points of rotating component one, rotating component two, push plate and mounting block together constitute a classic four-bar linkage mechanism. The mechanism can reliably and accurately convert the linear motion output by the hydraulic telescopic rod into the swinging motion required by the locking rod to achieve locking or unlocking. The motion is certain and the mechanism has high reliability.

[0020] This utility model has the following beneficial effects: 1. This utility model, by setting up a linkage mechanism composed of a motor, a circular block, gear teeth and a slider, realizes the automatic movement of the drilling device on the machine tool track, and uses a belt drive mechanism to synchronously drive a soft brush to clean the track. This solves the problems in the prior art where coupling processing is mostly done manually in single pieces, resulting in low efficiency and the track is easily blocked by chips, affecting operation. It achieves the technical effect of continuous automated processing and ensuring smooth operation.

[0021] 2. This utility model, by setting up an installation mechanism consisting of an installation groove, an installation block, a hydraulic telescopic rod, a push plate and a connecting rod assembly, uses a hydraulically driven clamping rod to achieve rapid pre-tightening of the equipment, which solves the problems of multiple people working together, cumbersome operation and safety hazards in the installation of heavy processing equipment in the prior art, and achieves the technical effect of simplifying the installation process and improving installation safety and convenience.

[0022] 3. This utility model integrates the automated moving linkage mechanism with the convenient installation mechanism, so that the whole device can not only efficiently complete batch processing tasks, but also save a lot of manpower and time in the installation and maintenance process, improve the efficiency of the equipment throughout its entire life cycle, and has a clever structure and strong practicality.

Detailed Implementation

[0025] 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. Example

[0026] Please refer to Figures 1 to 5 This utility model provides a drilling device for coupling processing, which aims to solve the problems of low efficiency and difficult and unsafe installation of existing coupling processing methods.

[0027] like Figure 1 As shown, a drilling device for processing couplings includes a machine tool 1, a linkage mechanism 2 is provided on the machine tool 1, a frame 5 is fixedly connected to the linkage mechanism 2, and an installation mechanism 3 is provided on the frame 5; a placement groove 4 for placing couplings is also provided on the upper surface of the machine tool 1.

[0028] Reference Figure 2 and Figure 3The linkage mechanism 2 is used to drive the frame 5 to move along the length of the machine tool 1. It includes a slide groove 201 opened on the machine tool 1, a gear tooth 202 fixedly connected in the slide groove 201, and a slider 203 slidably connected to the slide groove 201. The frame 5 is fixedly connected to the upper surface of the slider 203. A motor 205 is fixedly connected to the slider 203. A circular block 206 is fixedly connected to the output end of the motor 205. A tooth groove 207 that meshes with the gear tooth 202 is opened on the outer periphery of the circular block 206. When the motor 205 drives the circular block 206 to rotate, the meshing transmission between the tooth groove 207 and the gear tooth 202 converts the rotational motion of the circular block 206 into the linear motion of the entire slider 203 along the slide groove 201.

[0029] Reference Figure 4 and Figure 5 The mounting mechanism 3 is used to install the drilling equipment on the frame 5. It includes a mounting groove 301 and a mounting block 302 opened at the lower end of the frame 5. The mounting block 302 can be plugged into the mounting groove 301. A hydraulic telescopic rod 304 is installed inside the mounting block 302. A push plate 305 is fixedly connected to the output end of the hydraulic telescopic rod 304. A locking rod 308 is rotatably connected to the mounting block 302. The push plate 305 and the locking rod 308 are connected by a rotating component 306 and a rotating component 307. The connection structure allows the locking rod 308 to rotate when the hydraulic telescopic rod 304 is activated, so that the distal end of the locking rod 308 can be engaged or disengaged from the inner wall of the mounting groove 301, thereby completing the rapid pre-fixing or release of the mounting block 302.

[0030] Please refer to Figure 2 and Figure 3 The cleaning assembly includes a first drive wheel 208 fixedly connected to the circular block 206, a second drive wheel 210 connected to the first drive wheel 208 via a belt 209, and a soft brush 212 fixedly connected to the second drive wheel 210. The first drive wheel 208 is coaxially fixed to the side of the circular block 206 near the motor 205, and the second drive wheel 210 is rotatably connected to the slider 203 via a fixing rod 211. When the motor 205 drives the circular block 206 to rotate, the power is transmitted to the second drive wheel 210 via the first drive wheel 208 and the belt 209, which drives the soft brush 212 to rotate synchronously. The bristles of the soft brush 212 continuously abut against the inner bottom surface of the slide groove 201, thereby cleaning the chips and dust in the slide groove 201 in real time during the movement of the slider 203.

[0031] Please refer to Figure 4 and Figure 5The mounting block 302 has a second position groove for accommodating and mounting the hydraulic telescopic rod 304, which is also known as position groove 2 303. The telescopic axis of the hydraulic telescopic rod 304 is perpendicular to the moving direction of the slider 203. The first end of the rotating component 1 306 is rotatably connected to the push plate 305, and the second end is rotatably connected to the middle of the locking rod 308. The first end of the rotating component 2 307 is rotatably connected to the locking rod 308, and the second end is rotatably connected to the inner wall of the mounting block 302. This four-bar linkage mechanism, consisting of the connection points of the rotating component 1 306, the rotating component 2 307, the push plate 305, and the mounting block 302, can accurately convert the linear motion output by the hydraulic telescopic rod 304 into the swing of the locking rod 308, thereby achieving the action of locking or releasing.

[0032] In a preferred embodiment, in order to facilitate the installation and positioning of the motor 205, the slider 203 is provided with a first position groove for accommodating and fixing the motor 205. The first position groove is the position groove 204, and the motor 205 is fixed in the position groove 204 by fasteners.

[0033] As another preferred embodiment, in order to achieve final secure locking of the mounting mechanism 3 and enhance the vibration and impact resistance of the mounting mechanism 3, a flange 309 is fixedly connected to the outer side wall of the mounting block 302; correspondingly, the frame 5 is also provided with a threaded hole 310 for mating with the flange 309. After the mounting block 302 is initially engaged in the mounting groove 301 by the locking rod 308, the bolt 311 can pass through the flange 309 and the threaded hole 310 on the frame 5 to securely lock the two together.

[0034] As another preferred embodiment, in order to better utilize the geometry of the mounting groove 301 to achieve reliable engagement, the cross-section of the mounting groove 301 is designed as a tapered structure that is narrow on the outside and wide on the inside; in conjunction with this, the locking rod 308 is integrally formed or fixedly connected between the rotating member 1 306 and the rotating member 2 307, and extends outward to a locking section that can engage with the inner wall of the mounting groove (301). When the locking rod 308 is driven to swing outward, the locking section can wedge into and lock onto the inner wall of the wide portion of the mounting groove 301.

[0035] Working principle: During equipment installation, the mounting block 302 with drilling equipment is first slid into the predetermined position along the mounting groove 301 on the frame 5. Then, the hydraulic telescopic rod 304 is activated, which pushes the push plate 305 upward. The push plate 305 drives the locking rod 308 to rotate outward through the linkage mechanism composed of rotating component 1 306 and rotating component 2 307. Since the mounting groove 301 has a structure that is narrow on the outside and wide on the inside, the outwardly rotating locking rod 308 will be firmly locked on the inner wall of the mounting groove 301, achieving initial and rapid fixation of the mounting block 302 and preventing it from slipping off. Finally, the bolts 311 are screwed into the flange 309 and the threaded holes 310 of the frame 5 to complete the final secure locking. This process does not require multiple people to support it, making it safe and convenient. During processing, the coupling to be processed is placed in the placement slot 4 of the machine tool 1. After the workpiece is drilled, the motor 205 in the linkage mechanism 2 is started. The motor 205 drives the circular block 206 to rotate. The tooth groove 207 on the circular block 206 meshes with the fixed gear tooth 202, driving the entire slider 203 and the fixed frame 5 and mounting mechanism 3 to move along the slide 201 to the next station. While moving, the power of the motor 205 is transmitted to the soft brush 212 through the transmission wheel 208, belt 209 and transmission wheel 210. The soft brush 212 rotates and cleans the slide 201, ensuring smooth and unobstructed movement, thereby realizing automated continuous processing of multiple workpieces.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
