Description

Technical Field

[0001] This utility model relates to the field of parts transportation technology, and in particular to a device for transporting parts in an intelligent production line. Background Technology

[0002] Intelligent production line component transport devices are key equipment for achieving automated industrial workflows, primarily used to automatically transfer precision parts between assembly stations, testing units, and storage areas. Through the coordinated control of mechanical structures and drive systems, these devices replace manual handling, significantly improving production line coordination and cycle time efficiency, and have become a core component of modern intelligent manufacturing systems.

[0003] In the field of parts transportation on intelligent production lines, existing equipment generally uses rigid clamping structures to hold parts. These clamps require customized jaws for different specifications of parts; for example, transporting cylindrical bearings requires V-groove jaws, while transferring gears requires the development of specialized clamps with toothed positioning grooves. Each time a part model is changed, the machine must be stopped to disassemble the old clamps and install new jaws, a single changeover operation taking more than 15 minutes, severely disrupting production continuity. More importantly, when clamping parts with irregular surfaces, such as irregularly shaped connectors or curved shells, the planar contact structure of the rigid clamps cannot adaptively conform to the part's contour, leading to localized stress concentration. Under transport vibration conditions, parts are prone to slippage or even detachment, causing minor scratches on the part's surface or, more seriously, production line jams and shutdowns. This compatibility defect and insufficient stability caused by structural rigidity has become a core bottleneck restricting the flexible upgrading of intelligent manufacturing.

[0004] Therefore, this application provides an apparatus for transporting parts in a smart production line to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a device for transporting parts in an intelligent production line, which solves the problems of existing transport devices having rigid clamps that require customized special claws for each part and poor clamping stability for irregular parts.

[0006] To solve the above-mentioned technical problems, this utility model provides a device for transporting parts in an intelligent production line, including a slide rail, a slide table that slides along the slide rail, and a transport motor on one side of the slide rail, which drives the slide table to move along the slide rail. A clamping assembly is fixedly installed on the top of the slide table; the clamping assembly includes a base housing fixed to the top of the slide table, and a movable housing is arranged parallel to one side of the base housing along the extension direction of the slide rail; a push rod motor is fixedly installed on the rear outer wall of the movable housing, and the push rod end of the push rod motor is vertically connected to the rear outer wall of the movable housing; a matrix arrangement of clamping pins is provided on the inner side walls of the base housing and the movable housing respectively; each clamping pin includes a pin shell and a pin post coaxially sleeved, the pin post is fixed, and the pin shell moves axially along the pin post; a spring is provided inside the pin shell, the front end of the spring abuts against the front end face of the inner cavity of the pin shell, and the rear end of the spring abuts against the front end face of the pin post; a radially protruding annular retaining edge is provided on the rear edge of the pin shell.

[0007] A further improvement of the present invention is that: a first mounting plate is fixedly installed on the front inner wall of the base shell and the movable shell, and a second mounting plate is fixedly installed on the rear inner wall of the base shell and the movable shell; the pin shell passes through the first mounting plate and the front end face of the annular flange abuts against the rear side of the first mounting plate, and the rear end of the pin is vertically fixed to the front side of the second mounting plate.

[0008] A further improvement of this utility model is that the front end of the pin housing protrudes from the front side of the first mounting plate, and a linear bearing bushing is provided between the outer wall of the pin housing and the first mounting plate.

[0009] A further improvement to the technical solution of this utility model is that the front end of the pin shell is covered with an elastic anti-slip pad.

[0010] A further improvement of the present invention is that the thickness of the first mounting plate is greater than 15 mm, and the total thickness of the first mounting plate and the corresponding housing is greater than 20 mm; the inner wall of the mounting hole of the first mounting plate and the outer diameter of the pin housing are fitted together to form an axial guide structure.

[0011] A further improvement of this utility model is that: a threaded mounting block is provided on the front side of the second mounting plate, and the rear end of the pin is machined with an internal thread and screwed and fixed with the threaded mounting block; the axis of the pin is perpendicular to the front side of the second mounting plate.

[0012] A further improvement of this utility model is that the annular retaining edge and the pin shell are integrally formed.

[0013] A further improvement of this utility model is that: several sets of fixing ear plates are symmetrically arranged on both sides of the bottom of the base housing, and bolt holes are opened through the fixing ear plates; a threaded blind hole is provided on the top of the slide, and a high-strength bolt passes through the bolt hole of the fixing ear plate and is screwed into the threaded blind hole of the slide.

[0014] A further improvement of this utility model is that the distribution density of the clamping pins on the inner sidewalls of the base shell and the movable shell is 9-16 pins per square decimeter; and the fixing surfaces of the rear ends of all clamping pins are on the same plane.

[0015] By adopting the above technical solution, this utility model has the following beneficial effects: 1. This utility model provides a device for transporting parts in an intelligent production line. The device utilizes a matrix arrangement of clamping pins on the inner walls of the base housing and the movable housing, combined with a pin housing axial movement structure along fixed pins and a spring buffer design. This allows each clamping pin to independently adapt to the surface contour of the part. When clamping irregularly shaped bearings or irregularly shaped connectors, the pin housing retracts along the pins under the pressure of the part. The spring dynamically adjusts the abutment force, forming a three-dimensional adaptive fit with the part surface, completely eliminating the problem of localized stress concentration caused by planar contact in traditional rigid clamps. Even during transportation, if strong vibrations occur, the matrix-distributed elastic clamping pins can still evenly distribute the load, preventing the parts from slipping and falling off.

[0016] 2. This utility model provides a device for transporting parts in an intelligent production line. This device provides dual guiding constraints during the axial movement of the pin housing through a clearance-fitting guiding structure between the first mounting plate and the pin housing, and a precise fit between the outer wall of the pin housing and the linear bearing bushing. The design of the first mounting plate, with a thickness greater than 15 mm, significantly enhances bending stiffness. Combined with the wear-resistant properties of the linear bearing bushing, it ensures that the pin housing maintains its vertical movement trajectory even after hundreds of reciprocating motions, avoiding the clamping center offset caused by guide clearance wear in traditional clamps. This structure allows the clamped pin group to maintain coplanar accuracy even after long-term use, providing zero-damage transportation assurance for precision gears, miniature pins, and other parts.

[0017] 3. This utility model provides a device for transporting parts in an intelligent production line. This device uses symmetrically arranged fixing lugs at the bottom of the base housing, combined with threaded mounting blocks on the second mounting plate, to vertically fix the pin, enabling modular and rapid assembly and disassembly of the clamping assembly. When changing part models, only high-strength bolts need to be removed to separate the entire clamping assembly from the slide table. Then, the clamping pin unit can be replaced by loosening the internal threads at the rear end of the pin. Compared to the traditional clamping jaw assembly and disassembly process, this design significantly reduces changeover time and requires no specialized tools, completely solving the problem of production line continuity interruptions caused by frequent changeovers.

[0024] The present invention will be further explained below with reference to specific embodiments.

[0025] like Figures 1-7 As shown, this embodiment provides a device for transporting parts in an intelligent production line, including a slide rail 1, a slide table 2 that slides along the slide rail 1, a transport motor 3 on one side of the slide rail 1, the transport motor 3 driving the slide table 2 to move along the slide rail 1; a clamping assembly 4 is fixedly installed on the top of the slide table 2; the clamping assembly 4 includes a base housing 41 fixed to the top of the slide table 2, a movable housing 42 parallel to one side of the base housing 41 along the extension direction of the slide rail 1; a push rod motor 43 is fixedly installed on the rear outer wall of the movable housing 42, the end of the push rod 44 of the push rod motor 43 is vertically connected to the rear outer wall of the movable housing 42; clamping pins 47 arranged in a matrix are provided on the inner side walls of the base housing 41 and the movable housing 42 respectively.

[0026] like Figures 3-7 As shown, in this embodiment, each clamping pin 47 includes a coaxially sleeved pin housing 471 and pin post 472. The pin post 472 is fixed, while the pin housing 471 moves axially along the pin post 472. A spring 474 is provided inside the pin housing 471. The front end of the spring 474 abuts against the front end face of the inner cavity of the pin housing 471, and the rear end of the spring 474 abuts against the front end face of the pin post 472. A radially protruding annular retaining edge 473 is provided at the rear end edge of the pin housing 471. The annular retaining edge 473 and the pin housing 471 are integrally formed. The distribution density of the clamping pins 47 on the inner sidewalls of the base housing 41 and the movable housing 42 is 9-16 per square decimeter. The rear end fixing surfaces of the pin posts 472 of all clamping pins 47 are on the same plane. This device utilizes a matrix arrangement of clamping pins 47 positioned on the inner walls of the base housing 41 and the movable housing 42, combined with an axial movement structure of the pin housing 471 along the fixed pin post 472 and a spring 474 buffer design. This allows each clamping pin 47 to independently adapt to the surface contour of the component. When clamping irregularly shaped bearings or irregularly shaped connecting parts, the pin housing 471 retracts along the pin post 472 under the pressure of the component. The spring 474 dynamically adjusts the abutment force, forming a three-dimensional adaptive fit with the surface of the component, completely eliminating the problem of localized stress concentration caused by planar contact in traditional rigid clamps. Even during transportation, when subjected to strong vibrations, the matrix-distributed elastic clamping pins 47 can still evenly distribute the load, preventing the component from slipping and falling off.

[0027] like Figures 3-7 As shown, in this embodiment, a first mounting plate 45 is fixedly installed on the front inner wall of the base housing 41 and the movable housing 42, and a second mounting plate 46 is fixedly installed on the rear inner wall of the base housing 41 and the movable housing 42. A pin housing 471 penetrates the first mounting plate 45, and the front end face of the annular flange 473 abuts against the rear side of the first mounting plate 45. The rear end of the pin 472 is vertically fixed to the front side of the second mounting plate 46. The front end of the pin housing 471 protrudes beyond the front side of the first mounting plate 45, and a linear bearing bushing 48 is provided between the outer wall of the pin housing 471 and the first mounting plate 45. The front end of the pin housing 471 is covered with an elastic anti-slip pad. The thickness of the first mounting plate 45 is greater than 15 mm, and the total thickness of the first mounting plate 45 and the corresponding housing is greater than 20 mm. The inner wall of the mounting hole of the first mounting plate 45 and the outer diameter of the pin housing 471 form an axial guide structure with a clearance fit. A threaded mounting block 475 is provided on the front side of the second mounting plate 46. The rear end of the pin 472 is machined with an internal thread and screwed tightly to the threaded mounting block 475. The axis of the pin 472 remains perpendicular to the front side of the second mounting plate 46. This device provides dual guiding constraints during the axial movement of the pin housing 471 through the clearance fit guiding structure between the first mounting plate 45 and the pin housing 471, and the precision fit between the outer wall of the pin housing 471 and the linear bearing bushing 48. The design of the first mounting plate 45, with a thickness greater than 15 mm, significantly enhances bending stiffness. Combined with the wear-resistant properties of the linear bearing bushing 48, it ensures that the pin housing 471 maintains its vertical movement trajectory even after hundreds of reciprocating motions, avoiding the clamping center offset caused by guide clearance wear in traditional clamps. This structure allows the clamping pin group 47 to maintain coplanar accuracy even after long-term use, providing zero-damage transportation assurance for precision gears, miniature pins, and other accessories.

[0028] like Figures 3-7 As shown, in this embodiment, several sets of fixing lugs 49 are symmetrically arranged on both sides of the bottom of the base housing 41, and bolt holes are opened on the fixing lugs 49; a threaded blind hole is provided on the top of the slide table 2, and a high-strength bolt passes through the bolt hole of the fixing lug 49 and is screwed into the threaded blind hole of the slide table 2. This device achieves modular and rapid assembly and disassembly of the clamping assembly 4 through the fixing lugs 49 symmetrically arranged at the bottom of the base housing 41, in conjunction with the threaded mounting block 475 on the second mounting plate 46 for vertical fixation of the pin 472. When changing the part model, only the high-strength bolt needs to be removed to separate the entire clamping assembly 4 from the slide table 2, and then the clamping pin 47 unit is replaced by loosening the internal thread at the rear end of the pin 472. Compared with the traditional clamping jaw assembly and disassembly process, this design greatly reduces the changeover operation time and does not require professional tools, completely solving the problem of production line continuity interruption caused by frequent changeovers.

[0029] This utility model also provides the operating principle of a device for transporting parts in an intelligent production line: The transport motor 3 drives the slide table 2 to move along the slide rail 1 to the part loading station. The push rod motor 43 pushes the movable housing 42 towards the base housing 41, so that the elastic anti-slip pads of the clamping pins 47 on both sides contact the part surface. When clamping irregularly shaped parts, the pin housing 471 retracts axially along the fixed pin 472 under the pressure of the part, compressing the internal spring 474 to generate an adaptive buffering force. At the same time, the guide structure formed by the first mounting plate 45 and the linear bearing bushing 48 ensures that the pin housing 471 moves vertically. The matrix-arranged clamping pins 47 dynamically adjust to the contour of the part to form a three-dimensional fit. After the adaptive clamping is completed, the transport motor 3 drives the slide table 2 to transport the part to the target station. The push rod motor 43 retracts the movable housing 42 to release the part, and the pin housing 471 returns to its initial position under the action of the spring 474. Throughout the process, the threaded mounting block 475 on the second mounting plate 46 maintains the pin 472 in a vertical fixed state to ensure stable clamping accuracy.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
