Description

Technical Field

[0001] This utility model belongs to the field of industrial automation technology, and more specifically, it relates to a mechanical module device with quickly replaceable parts. Background Technology

[0002] In industrial automated production lines, mechanical modules are widely used in automated operations such as material handling, parts assembly, and welding, playing a crucial role in improving production efficiency and product quality. Existing mechanical module devices typically consist of a support structure that forms the running frame, with a drive mechanism propelling the mechanical module to move within the space defined by the support structure. Simultaneously, a transmission device converts the driving force into actual kinetic energy, enabling diverse automated operations such as material handling and parts assembly.

[0003] Existing application number CN202123099814.X discloses a fully automatic robotic arm with limit-positioning capability for easy installation. It includes a turntable and a disassembly / assembly mechanism. A cam divider is installed at the bottom input end of the turntable, and the cam divider is connected to a ladder via the turntable. An elbow joint is provided at the top of the handle, and a track is rotatably connected to the handle via the elbow joint. The disassembly / assembly mechanism for quick loading and unloading is installed at the bottom of the track. This invention addresses the problem of high purchase costs for existing robotic arms. In some assembly lines with fully automated requirements but low precision, high-cost robotic arms are unsuitable, increasing production costs. Furthermore, existing robotic arms suffer from the drawback of inconvenient gripper replacement. This invention provides a fully automatic robotic arm with limit-positioning capability for easy installation. The limit-positioning and guiding of the robotic arm is achieved through a simple mechanical structure, effectively reducing the purchase cost of the robotic arm. In addition, it makes the replacement of gripper components of existing robotic arms quicker and more versatile.

[0004] Based on the above, in existing mechanical module devices, the mechanical claw components are mostly fastened to the inside of the module using multiple sets of bolts. When the production process needs to adapt to diversified production modes and the mechanical claw components need to be replaced, operators often need to use multiple tools such as wrenches and screwdrivers, going through a cumbersome disassembly and installation process. This not only consumes a lot of time and energy, but also leads to extended production line interruption time due to frequent downtime, restricting production efficiency and capacity continuity. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a mechanical module device with quickly replaceable components. This addresses the issue in existing mechanical module devices where the mechanical claw components are typically secured inside the module with multiple sets of bolts. When production processes require adapting to diverse production modes and necessitate replacing the mechanical claw components, operators often need to use wrenches, screwdrivers, and other tools, undergoing a cumbersome disassembly and installation process. This not only consumes significant time and effort but also leads to prolonged production line downtime due to frequent shutdowns, hindering production efficiency and capacity continuity.

[0006] The purpose and effectiveness of this utility model's mechanical module device with quickly replaceable components are achieved through the following specific technical means:

[0007] A mechanical module device with quick-change components includes a support frame, a mechanical module body, a mounting base, a mechanical claw, an upper connecting base, a lower connecting base, a through hole, a quick-change assembly, and an anti-loosening assembly. The mechanical module body is installed inside the support frame; the mounting base is installed at the bottom of the mechanical module body; the mechanical claw is located at the bottom of the mounting base; the upper connecting base is fixedly installed at the bottom of the mounting base; the lower connecting base is fixedly installed at the top of the mechanical claw; the through hole is formed in the middle of the upper and lower connecting bases; the quick-change assembly is located at the bottom of the mounting base; and the anti-loosening assembly is located inside the upper connecting base.

[0008] Furthermore, the quick-change assembly includes: a knob, a transmission rod, and a first bevel gear. The knob is rotatably connected inside the upper connecting seat; the transmission rod is rotatably connected inside the upper connecting seat; and two sets of the first bevel gear are provided, with the two sets of the first bevel gears coaxially and fixedly installed on the outside of the transmission rod.

[0009] Furthermore, the quick-change assembly also includes: a threaded screw and a second bevel gear. Two sets of threaded screws are provided, and the two sets of threaded screws are rotatably connected inside the upper connecting seat. Two sets of second bevel gears are provided, and the two sets of second bevel gears are coaxially fixedly installed at one end of the two sets of threaded screws, and the second bevel gear and the first bevel gear mesh with each other.

[0010] Furthermore, the quick-change assembly also includes: a transmission frame and a limiting pin. The transmission frame is provided in two sets, which are slidably connected inside the upper connecting seat and threadedly connected to the outside of two sets of threaded screws. The limiting pin is provided in multiple sets, which are fixedly installed on the outside of the two sets of transmission frames.

[0011] Furthermore, the quick-change assembly also includes: a mounting groove and a limiting hole, wherein the mounting groove is formed inside the lower connector; and multiple sets of limiting holes are provided, wherein multiple sets of limiting holes are formed inside the lower connector.

[0012] Furthermore, the anti-loosening component includes a sliding groove and a transmission plate, wherein the sliding groove is formed on the front side of the upper connecting seat; and the transmission plate is slidably connected inside the sliding groove.

[0013] Furthermore, the anti-loosening component also includes: a baffle and a return spring, the baffle being fixedly installed on the top of the transmission plate; one end of the return spring being fixedly installed inside the sliding groove, and the other end of the return spring being fixedly installed on the back of the transmission plate.

[0014] Furthermore, the anti-loosening component also includes: a toothed ring and a limiting toothed groove, wherein the toothed ring is fixedly installed on the outside of the knob; and the limiting toothed groove is fixedly installed on one side of the transmission plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] Firstly, this invention features a quick-change assembly that converts rotary motion into linear motion through the coordinated operation of components such as a knob, transmission rod, bevel gear, and threaded screw. Simply rotating the knob drives the transmission frame to precisely insert the limit pin into the limit hole, quickly completing the fixed connection between the mechanical claw and the mounting base. Compared to traditional bolt fixing methods, this significantly shortens replacement time and substantially improves production efficiency.

[0017] Secondly, this utility model has an anti-loosening component. Through the cooperation of the reset spring, transmission plate, baffle, toothed ring and limiting tooth groove, in the non-operating state, the transmission plate drives the baffle to cover the knob under the action of the reset spring, and the limiting tooth groove is embedded in the toothed ring, forming double protection. It can effectively prevent the knob from being corroded and contaminated with oil, and resist vibration interference to prevent the knob from becoming loose.

[0018] This utility model has the advantages of simple operation, stable installation, and anti-loosening protection. It only requires pushing the baffle to release the locking of the toothed ring by the limiting tooth groove, and rotating the knob to quickly replace the mechanical claw parts without the need for multiple tools. It not only meets the needs of industrial automation production lines for rapid replacement of parts in diversified production, but also ensures the reliability of the device during operation, effectively reduces downtime, and improves the continuous operation capability of the production line.

[0028] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0029] Example 1:

[0030] As attached Figure 1 To be continued Figure 7 As shown:

[0031] This utility model provides a mechanical module device with quick-change components, including a support frame 1, a mechanical module body 2, a mounting base 3, a mechanical claw 4, an upper connecting base 5, a lower connecting base 6, a through hole 7, and a quick-change assembly. The mechanical module body 2 is installed inside the support frame 1; the mounting base 3 is installed at the bottom of the mechanical module body 2; the mechanical claw 4 is located at the bottom of the mounting base 3; the upper connecting base 5 is fixedly installed at the bottom of the mounting base 3; the lower connecting base 6 is fixedly installed at the top of the mechanical claw 4; the through hole 7 is opened in the middle of the upper connecting base 5 and the lower connecting base 6; and the quick-change assembly is located at the bottom of the mounting base 3.

[0032] The quick-change assembly includes a knob 501, a transmission rod 503, and a first bevel gear 504. The knob 501 is rotatably connected inside the upper connecting seat 5; the transmission rod 503 is rotatably connected inside the upper connecting seat 5; two sets of first bevel gears 504 are provided, and the two sets of first bevel gears 504 are coaxially fixedly installed on the outside of the transmission rod 503.

[0033] The quick-change assembly also includes: a threaded screw 505 and a second bevel gear 506. Two sets of threaded screws 505 are provided, and the two sets of threaded screws 505 are rotatably connected inside the upper connecting seat 5. Two sets of second bevel gears 506 are provided, and the two sets of second bevel gears 506 are coaxially fixedly installed at one end of the two sets of threaded screws 505 respectively. The second bevel gears 506 and the first bevel gears 504 mesh with each other.

[0034] The quick-change assembly also includes: a transmission frame 507 and a limiting pin 508. Two sets of transmission frames 507 are provided, and the two sets of transmission frames 507 are slidably connected inside the upper connecting seat 5. The two sets of transmission frames 507 are threadedly connected to the outside of two sets of threaded screws 505. Multiple sets of limiting pins 508 are provided, and multiple sets of limiting pins 508 are fixedly installed on the outside of the two sets of transmission frames 507.

[0035] The quick-change component also includes: a mounting slot 601 and a limiting hole 602. The mounting slot 601 is opened inside the lower connecting seat 6. Multiple sets of limiting holes 602 are provided, and multiple sets of limiting holes 602 are opened inside the lower connecting seat 6.

[0036] The specific usage and function of this embodiment are as follows:

[0037] When a quick replacement of the robotic gripper 4 is required, first, precisely align the lower connecting seat 6 and the upper connecting seat 5 on the upper part of the robotic gripper 4. Guided by the mounting groove 601, the upper connecting seat 5 smoothly embeds into the lower connecting seat 6. Then, use a tool to rotate the knob 501. The rotation of the knob 501 is transmitted through the transmission rod 503 to the two coaxially arranged first bevel gears 504, causing them to rotate synchronously. The meshing transmission between the first bevel gear 504 and the second bevel gear 506 causes the two sets of threaded screws 505 to begin rotating. Thanks to the special design of the threaded screws 505 with opposite rotation at both ends, the two sets of transmission frames 507 achieve relative movement under threaded drive, and the synchronous drive mechanism of the double screws effectively improves the stability of the transmission frames 507 during movement. As the transmission frames 507 move towards each other, the multiple sets of limiting pins 508 fixed on the transmission frames 507 are precisely inserted into the limiting holes 602 of the lower connecting seat 6, quickly and securely completing the connection and fixation between the mounting seat 3 and the robotic gripper 4 through mechanical limiting. The through hole 7, which connects the lower connecting seat 6 and the upper connecting seat 5, facilitates the connection of wire harnesses, pipes, bushings and other structures between the mounting seat 3 and the mechanical claw 4.

[0038] Example 2:

[0039] Based on Example 1, such as Figures 1 to 7 As shown, it also includes an anti-loosening component, which is disposed inside the upper connector 5.

[0040] The anti-loosening component includes a sliding groove 509 and a transmission plate 511. The sliding groove 509 is opened on the front side of the upper connecting seat 5; the transmission plate 511 is slidably connected inside the sliding groove 509.

[0041] The anti-loosening component also includes a baffle 510 and a return spring 512. The baffle 510 is fixedly installed on the top of the transmission plate 511. One end of the return spring 512 is fixedly installed inside the sliding groove 509, and the other end of the return spring 512 is fixedly installed on the back of the transmission plate 511.

[0042] The anti-loosening component also includes: a gear ring 502 and a limiting gear groove 513. The gear ring 502 is fixedly installed on the outside of the knob 501; the limiting gear groove 513 is fixedly installed on one side of the transmission plate 511.

[0043] The specific usage and function of this embodiment are as follows:

[0044] The return spring 512, under its elastic action, drives the transmission plate 511 to move inside the sliding groove 509, which serves as a guide when the transmission plate 511 moves. During this process, the transmission plate 511 drives the top baffle 510 to form a tight shield around the top of the knob 501, effectively isolating it from corrosive media and oil stains, thus extending the service life of the knob 501. At the same time, the limiting tooth groove 513 on the side of the transmission plate 511 precisely engages with the toothed ring 502 on the outside of the knob 501, forming a mechanical locking structure that can resist high-frequency vibrations and external interference generated during the operation of the main body 2 of the mechanical module, ensuring that the knob 501 remains secure when not in operation.

[0045] When the knob 501 needs to be operated, the operator applies force through the anti-slip friction groove on the surface of the baffle 510, which drives the transmission plate 511 to overcome the elastic force of the return spring 512 and slide backward along the sliding groove 509. During this process, the limiting tooth groove 513 simultaneously disengages from the toothed ring 502, completely releasing the locking constraint on the knob 501, allowing the knob 501 to rotate smoothly.
