Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically to a workpiece secondary positioning platform. Background Technology

[0002] In the production process, workpieces are typically handled by robotic arms. As the robotic arm moves a workpiece from one device to another, the workpiece's angle changes. Therefore, the angle needs to be adjusted again before placing the workpiece in the next device to ensure the robotic arm can position it at the appropriate angle for subsequent processing operations such as welding and cutting. Currently, the secondary positioning process typically involves first placing the workpiece on a support platform, then using a cylinder to push it to a limiting device. This method is inefficient and labor-intensive. Furthermore, existing secondary positioning devices struggle to flexibly position workpieces of different specifications, further hindering production efficiency.

[0003] To address the shortcomings of existing technologies, people have conducted long-term explorations and proposed various solutions. For example, Chinese patent literature discloses a secondary positioning device [CN202020718861.4], which includes a base, a support plate, a first support member, a second support member, and an adjusting member. The support plate is located above the base and is inclined relative to the base. A limiting plate is provided at the end of the support plate. The first support member is located between the base and the support plate, and its two ends are hinged to the tops of the base and the support plate, respectively. The second support member is located between the base and the support plate, and its two ends are hinged to the ends of the base and the support plate, respectively. The length of the first support member is greater than the length of the second support member. The adjusting member is located on the second support member and is used to adjust the distance between the end of the support plate and the connection point of the second support member relative to the base.

[0004] The above solution has solved the problems of low efficiency and high labor intensity in the existing secondary positioning device to a certain extent. However, the solution still has many shortcomings, such as difficulty in flexibly positioning workpieces of different specifications, which delays production efficiency. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems by providing a workpiece secondary positioning platform.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a workpiece secondary positioning platform, comprising a platform body, an adjustable guide wheel stop structure on one side of the upper end face of the platform body and a plurality of movable pushing mechanisms arranged at equal intervals on the other side, and an auxiliary pressing component between two adjacent movable pushing mechanisms, a side pushing structure on one end of the upper end face of the platform body and a fixed baffle structure correspondingly provided on the other end, and a workpiece positioning space is formed on the upper end face of the platform body and circumferentially inside the adjustable guide wheel stop structure, the fixed baffle structure, the movable pushing mechanism, the auxiliary pressing component and the side pushing structure.

[0007] In the above-mentioned workpiece secondary positioning platform, the adjustable guide wheel stop structure includes a strip-shaped sliding adjustment groove disposed on one side of the upper end face of the platform body, and a number of adjustable rotating guide wheels are disposed in the strip-shaped sliding adjustment groove.

[0008] In the above-mentioned workpiece secondary positioning platform, a locking frame corresponding to the strip-shaped sliding adjustment groove is rotatably connected to one side of the platform body through a vertically arranged positioning connecting rod. The upper end face of the locking frame is provided with a number of positioning slots for positioning the connecting rod on the adjustable rotating guide wheel.

[0009] The guide wheel position can be adjusted according to the workpiece width by means of the strip sliding adjustment groove and adjustable rotating guide wheel, and stable positioning can be achieved in conjunction with the positioning groove of the locking frame.

[0010] In the above-mentioned workpiece secondary positioning platform, the movable pushing mechanism includes several clearance slots disposed on the side of the upper end face of the platform body away from the adjustable guide wheel stop structure. Side guide wheels are disposed in the clearance slots through connecting horizontal plates, and the bottom of the side guide wheels are connected to sliding connecting seats through lifting adjustment rods. The sliding connecting seats are connected to each other through a linkage horizontal frame.

[0011] In the above-mentioned workpiece secondary positioning platform, the sliding connecting seat is provided with sliding insertion parts on both sides, and the side walls of the clearance through groove are provided with guide grooves for the sliding insertion parts to be inserted.

[0012] In the above-mentioned workpiece secondary positioning platform, the upper ends of the lifting adjustment rods are connected by a linkage crossbar, and the bottom of the linkage crossbar is connected to a drive crossbar. The drive crossbar passes through the strip clearance groove of the linkage crossbar and is driven by a lifting cylinder.

[0013] In the above-mentioned workpiece secondary positioning platform, a push-pull cylinder is installed inside the main body of the platform, and the output end of the push-pull cylinder is connected to the linkage crossbeam.

[0014] The mobile pusher mechanism adjusts the height of the side guide wheels through the lifting cylinder, and the pusher pull cylinder drives the linkage crossbeam to adjust the lateral position, adapting to the side positioning requirements of different workpieces. It has high positioning flexibility and can adapt to the positioning of more specifications of workpieces.

[0015] In the above-mentioned workpiece secondary positioning platform, the auxiliary clamping assembly includes a sliding clamping adjustment groove disposed between two adjacent clearance through grooves, and a clamping rod disposed in the sliding clamping adjustment groove. The clamping rod is driven by a clamping cylinder disposed on the outer wall of the platform body.

[0016] In the above-mentioned workpiece secondary positioning platform, the side pusher structure includes several strip-shaped pusher grooves arranged parallel to each other at one end of the platform body. A pusher linkage rod arranged longitudinally is inserted into the strip-shaped pusher groove. The upper end of the pusher linkage rod is connected to a pusher crossbeam located on the upper surface of the platform body, and the lower end of the pusher linkage rod is connected through a drive linkage and driven by a pusher cylinder.

[0017] The sliding clamping adjustment groove of the auxiliary clamping assembly can adjust the position of the clamping rod to adapt to the clamping requirements of different areas of the workpiece.

[0018] In the above-mentioned workpiece secondary positioning platform, the fixed baffle structure includes a fixed baffle disposed at the end of the platform body away from the side pusher structure, and the fixed baffle is provided with mounting through grooves on both sides for mounting the movable positioning plate.

[0019] The fixed baffle structure can be adapted to different positioning specifications of the workpiece end by installing and adjusting the movable positioning plates on both sides.

[0020] Compared with existing technologies, the advantages of this invention are as follows: the side-pushing structure, in conjunction with the fixed baffle structure, enables axial positioning of the workpiece; the adjustable guide wheel stop structure, in conjunction with the movable pushing mechanism, enables radial positioning of the workpiece; secondly, the auxiliary clamping component provides additional clamping force after positioning, meeting the dual requirements of accuracy and stability for secondary positioning. While ensuring positioning accuracy and stability, it significantly improves the versatility of workpieces of various specifications, making it suitable for secondary precision positioning scenarios of various workpieces.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1-4 As shown, a workpiece secondary positioning platform includes a platform body 1. An adjustable guide wheel stop structure 2 is provided on one side of the upper end face of the platform body 1, and a plurality of movable pusher mechanisms 3 are provided on the other side. An auxiliary pressing component 4 is provided between two adjacent movable pusher mechanisms 3. A side pusher structure 5 is provided at one end of the upper end face of the platform body 1, and a fixed baffle structure 6 is provided at the other end. The upper end face of the platform body and the adjustable guide wheel stop structure 2, the fixed baffle structure 6, the movable pusher mechanism 3, the auxiliary pressing component 4 and the side pusher structure 5 form a workpiece positioning space 7 on the inner circumference.

[0028] The adjustable guide wheel structure 2 includes a strip-shaped sliding adjustment groove 21 located on one side of the upper end face of the base body 1, and a number of adjustable rotating guide wheels 22 are provided in the strip-shaped sliding adjustment groove 21.

[0029] The adjustable rotating guide wheel 22 can adjust the position and positioning density according to the length and width of the workpiece.

[0030] As can be seen, a locking frame 24 corresponding to the strip-shaped sliding adjustment groove 21 is rotatably connected to one side of the base body 1 via a vertically arranged positioning link 23. The upper end face of the locking frame 24 is provided with a number of positioning slots 25 for positioning the connecting rod on the adjustable rotating guide wheel 22.

[0031] After the position of the adjustable rotating guide wheel 22 is adjusted, the connecting rod of the adjustable rotating guide wheel 22 is locked by the positioning slot 25 on the locking frame 24 to fix the position of the guide wheel and ensure the stability during positioning.

[0032] Furthermore, the movable pushing mechanism 3 includes several clearance slots 31 disposed on the side of the upper surface of the base body 1 away from the adjustable guide wheel stop structure 2. Side guide wheels 33 are disposed in the clearance slots 31 through the connecting horizontal plate 32, and the bottom of the side guide wheels 33 is connected to a sliding connecting seat 35 through the lifting adjustment rod 34. The sliding connecting seats 35 are connected to each other through the linkage horizontal frame 36.

[0033] Furthermore, the sliding connector 35 is provided with sliding insertion parts 351 on both sides, and the side walls of the clearance through groove 31 are provided with guide grooves 352 for the sliding insertion parts 351 to be inserted.

[0034] Specifically, the upper ends of the lifting adjustment rods 34 are connected by a linkage crossbar 37, and the bottom of the linkage crossbar 37 is connected to a drive crossbar 38. The drive crossbar 38 passes through the strip clearance slot 361 of the linkage crossbar 36 and is driven by the lifting cylinder 39.

[0035] More specifically, the main body 1 of the platform is equipped with a push-pull cylinder 362, and the output end of the push-pull cylinder 362 is connected to the linkage crossbeam 36.

[0036] The sliding connector 35 cooperates with the guide groove 352 of the clearance through groove 31 through the sliding insertion parts 351 on both sides to ensure lateral movement stability;

[0037] The push-pull cylinder 362 drives the linkage cross frame 36, which in turn moves the sliding connecting seat 35 and the side guide wheel 33 laterally, thereby achieving the push-tight positioning of the workpiece on the other side.

[0038] The lifting cylinder 39 drives the lifting adjustment rod 34 through the drive frame 38 and the linkage crossbar 37 to adjust the height of the side guide wheel 33, adapting to the positioning requirements of workpieces of different thicknesses.

[0039] In detail, the auxiliary clamping assembly 4 includes a sliding clamping adjustment groove 41 disposed between two adjacent clearance grooves 31, and a clamping rod 42 disposed in the sliding clamping adjustment groove 41. The clamping rod 42 is driven by a clamping cylinder 43 disposed on the outer wall of the base body 1.

[0040] The clamping cylinder 43 drives the clamping rod 42 to slide in the groove, applying pressure to the workpiece area between adjacent movable pusher mechanisms 3, thereby enhancing positioning stability.

[0041] Preferably, the side pushing structure 5 includes several strip-shaped pushing grooves 51 arranged parallel to each other at one end of the main body 1. A pushing linkage rod 52 arranged longitudinally is inserted into the strip-shaped pushing groove 51. A pushing crossbeam 53 located on the upper surface of the main body 1 is connected to the upper end of the pushing linkage rod 52, and the lower end of the pushing linkage rod 52 is connected by a driving link and driven by a pushing cylinder 54.

[0042] The pusher cylinder 54 drives the pusher linkage rod 52 to move longitudinally through the drive linkage rod, so that the pusher crossbeam 53 pushes the workpiece to move in the direction of the fixed baffle structure 6, thereby clamping the two ends of the workpiece.

[0043] Furthermore, the fixed baffle structure 6 includes a fixed baffle 61 located at the end of the platform body 1 away from the side pusher structure 5, and the fixed baffle 61 has mounting slots 62 on both sides for mounting movable positioning plates.

[0044] The fixed baffle 61 serves as the reference surface for longitudinal positioning of the workpiece. The mounting slots 62 on both sides can be used to install and adjust the position of the movable positioning plate to adapt to different positioning requirements at the end of the workpiece. Together with the side pusher structure 5, it can achieve precise longitudinal positioning of the workpiece.

[0045] In summary, the principle of this embodiment is as follows: the adjustable guide wheel stop structure 2, with the help of the strip sliding adjustment groove 21 and the adjustable rotating guide wheel 22, combined with the locking frame 24 to fix the position, forms an adjustable reference on one side of the lateral direction; the movable pusher mechanism 3 drives the side guide wheel 33 to move laterally through the pusher cylinder 362, and adjusts the height with the lifting adjustment rod 34 to push the workpiece from the other side of the lateral direction; the side pusher structure 5, under the action of the pusher cylinder 54, drives the pusher crossbeam 53 to push the workpiece towards the fixed baffle structure 6, and the fixed baffle 61 and the movable positioning plate form a longitudinal reference; the pressing rod 42 of the auxiliary pressing component 4, driven by the pressing cylinder 43, further presses the key parts of the workpiece, and finally, all the structures together complete the secondary precise positioning of the workpiece in the workpiece positioning space 7.
