Description

Technical Field

[0001] The utility model relates to a strip sample processing positioning tool, belonging to the technical field of positioning tooling. Background Art

[0002] At present, sample processing has been widely used in various types of processing equipment. Especially for some workpieces that require precision processing or high-precision positioning, reasonable tooling design is particularly important. Strip samples are a common processing object. Since flat strip samples usually have a large aspect ratio and a small thickness, they are not easy to position and fix during the processing. After searching the prior art, it was found that the Chinese patent with announcement number CN205043501U disclosed a milling machine sample processing mold. The patent uses sample clamping bolts for clamping, which requires manual operation during use. Manual adjustment is not only time-consuming, but also easily affects the quality of the final product. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a strip sample processing positioning tool, which can significantly improve the positioning and clamping efficiency during the processing and reduce manual operations.

[0004] In order to solve the above technical problems, the technical solution of the utility model is: a strip sample processing and positioning tool, comprising:

[0005] A workbench, wherein a plurality of workstations are arranged at intervals in the transverse direction, and at least one guide groove is provided in the longitudinal direction at a position corresponding to each workstation;

[0006] at least one movable mounting plate, the movable mounting plate being slidably mounted on a corresponding station of the workbench through the guide groove;

[0007] At least one pair of transverse clamping mechanisms, each pair of transverse clamping mechanisms being longitudinally arranged at corresponding workstations of the workbench, wherein at least one of the transverse clamping mechanisms is mounted on the corresponding movable mounting plate, and each transverse clamping mechanism is provided with a centering seat suitable for placing a workpiece;

[0008] At least one pair of corner clamping mechanisms, each pair of the corner clamping mechanisms is longitudinally arranged on the corresponding workstation of the workbench, wherein at least one of the corner clamping mechanisms is installed on the corresponding movable mounting plate, and each of the corner clamping mechanisms is provided with at least one lower pressure arm, and the corner clamping mechanism is suitable for driving the lower pressure arm to clamp the workpiece located on the corresponding centering seat.

[0009] Furthermore, a specific structure of a workbench is provided, the workbench comprising:

[0010] A bottom plate, wherein the bottom plate is provided with at least one sliding groove in a transverse direction;

[0011] A pair of raising blocks, the raising blocks being slidably mounted on the bottom plate along the slide grooves;

[0012] A sub-plate, the sub-plate being mounted on a pair of the spacer blocks, the sub-plate being adapted to move laterally on the bottom plate via the spacer blocks;

[0013] The guide groove is provided on the sub-plate.

[0014] Furthermore, in order to better support the workpiece, the strip specimen processing and positioning fixture further includes at least one sub-support plate, which is slidably arranged on the workbench through the guide groove and is located between a pair of transverse clamping mechanisms corresponding to the workstation;

[0015] The sub-support plate is provided with an adjustable screw, and the adjustable screw is suitable for being actuated to abut against a workpiece arranged on a centering seat of the transverse clamping mechanism.

[0022] Furthermore, the transverse clamping mechanism is a centering clamp, and the centering seat is arranged on the centering clamp. By adopting the above technical solution, the utility model has the following beneficial effects:

[0023] In this utility model, the position of the movable mounting plate is first adjusted so that the distance between the pair of transverse clamping mechanisms on the movable mounting plate at a workstation meets the required workpiece length. The workpiece's ends are then placed on the centering seats of the corresponding transverse clamping mechanisms, which are then clamped. The angular clamping mechanism then drives the lower pressure arm to clamp the workpiece on the centering seats. Furthermore, by arranging multiple workstations on the workbench, multiple workpieces can be clamped simultaneously. This not only effectively improves clamping efficiency but also allows for the simultaneous clamping of different workpieces.

[0024] In addition, the sub-support plate is used in conjunction with the lateral clamping mechanism. By adjusting the adjustable screw, the workpiece can obtain additional support during the processing, thereby preventing deformation or offset during the processing.

[0027] Figure 2 This is the main view of the strip specimen processing and positioning tool of the present invention. DETAILED DESCRIPTION

[0028] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0029] like Figure 1-2 As shown, a strip specimen processing and positioning tool comprises:

[0030] The workbench 1 has three workstations spaced apart in the transverse direction, and a pair of guide grooves are provided in the longitudinal direction at the position corresponding to each workstation;

[0031] Three pairs of movable mounting plates 2, the movable mounting plates 2 being slidably mounted on corresponding positions of the workbench 1 through guide grooves;

[0032] Three pairs of transverse clamping mechanisms 3, each pair of transverse clamping mechanisms 3 is longitudinally arranged at a corresponding station of the workbench 1, wherein the three pairs of transverse clamping mechanisms 3 are mounted on corresponding movable mounting plates 2, and the transverse clamping mechanisms 3 are provided with a centering seat suitable for placing a workpiece 4;

[0033] Three pairs of corner clamping mechanisms 5, each pair of corner clamping mechanisms 5 is arranged longitudinally on the corresponding workstation of the workbench 1, wherein the three pairs of corner clamping mechanisms 5 are installed on the corresponding movable mounting plates 2, and each corner clamping mechanism 5 is provided with a lower pressure arm, and the corner clamping mechanism 5 is suitable for driving the lower pressure arm to clamp the workpiece 4 located on the corresponding centering seat.

[0034] In this embodiment, if Figure 1 As shown, first, by adjusting the position of the movable mounting plate 2, the distance between the pair of transverse clamping mechanisms 3 on the movable mounting plate 2 at one station is made to meet the length requirements of the workpiece 4. Then, the two ends of the workpiece 4 are placed on the corresponding centering seats of the transverse clamping mechanism 3, and the transverse clamping mechanism 3 is used to complete the clamping. Then, the angle clamping mechanism 5 is used to drive the lower pressure arm 6 to clamp the workpiece 4 located on the centering seat. At the same time, by setting up multiple stations on the workbench 1, multiple workpieces 4 can be clamped at the same time. This not only effectively improves the efficiency of clamping, but can also be used to clamp different workpieces 4 at the same time.

[0035] In this embodiment, the number of movable mounting plates 2 and the number of transverse clamping mechanisms 3 and corner pressing mechanisms 5 correspond one to one, that is, one transverse clamping mechanism 3 and one corner pressing mechanism 5 are installed on one movable mounting plate 2.

[0036] The workbench 1 in this embodiment can be a milling processing platform of a vertical machining center of model VMC850L.

[0037] Specifically, such as Figure 1-2 As shown, the workbench 1 includes:

[0038] The bottom plate 11 is provided with five slide grooves in the transverse direction;

[0039] A pair of raising blocks 12, the raising blocks 12 are slidably mounted on the bottom plate 11 along the slide grooves;

[0040] The sub-plate 13 is mounted on a pair of spacer blocks, and the sub-plate 13 is adapted to move laterally on the base plate 11 through the spacer blocks 12;

[0041] The guide groove is provided on the sub-plate 13 .

[0042] In this embodiment, if Figure 1-2 As shown, the workbench 1 allows the entire strip specimen processing and positioning fixture to move freely in the horizontal direction. For example, for a longer workpiece 4, the effective length of the workbench can be extended by adjusting the position of the spacers 12. Furthermore, this design facilitates overall cleaning and maintenance, as the various components can be relatively easily disassembled and reassembled. In actual use, spacers 12 of varying heights or adjustable heights can be selected to further enhance the adaptability of the workbench, depending on specific production requirements.

[0043] In some embodiments, the number of chutes is not limited to five and can be set according to specific needs.

[0044] Specifically, such as Figure 1 As shown, the strip specimen processing and positioning tool further includes three sets of sub-support plates 7, which are slidably arranged on the workbench 1 through guide grooves and are located between a pair of transverse clamping mechanisms 3 corresponding to the workstations;

[0045] An adjustable screw is provided on the sub-support plate 7 , and the adjustable screw is suitable for being actuated to abut against the workpiece 4 provided on the centering seat of the transverse clamping mechanism 3 .

[0046] In this embodiment, if Figure 1 As shown, the sub-support plate 7 is designed with an adjustable screw as a support mechanism. The use of the adjustable screw enables the operator to manually adjust the support height, providing a precise support point for the workpiece 4. During use, the operator first slides the sub-support plate 7 to the appropriate position according to the length and shape of the workpiece. Then, by rotating the adjustable screw, adjust its height until the top of the screw just touches the bottom of the workpiece 4. And the use of adjustable screws allows the operator to make fine adjustments according to the specific conditions of the workpiece 4, ensuring that the workpiece 4 is evenly and properly supported. For slight deformations that may occur during the processing process, the operator can compensate at any time by fine-tuning the height of the screw to maintain the stability of the workpiece.

[0047] In this embodiment, the number of sub-support plates 7 corresponds to the number of workpieces 4.

[0048] Specifically, such as Figure 1 As shown, the corner pressing mechanism 5 may have the following structure, including:

[0049] Angle cylinder, the angle cylinder is installed on the movable mounting plate 2, and a driving rod is provided on the angle cylinder;

[0050] The lower pressure arm is installed on the driving rod of the corner cylinder.

[0051] In this embodiment, if Figure 1 As shown, during use, after the workpiece 4 is placed on the centering seat, the driving rod of the angle cylinder drives the lower pressure arm to rotate. Simultaneously, during this rotation, the lower pressure arm descends, rotating from its initial position to a clamping position, firmly pressing the workpiece 4 against the centering seat. Furthermore, the clamping end of the lower pressure arm in this embodiment is equipped with a replaceable pressure head.

[0052] Specifically, such as Figure 1 As shown, the lower pressing arm includes a connecting end and a pressing end, wherein the connecting end is connected to the corner cylinder;

[0053] The cross-sectional area of ​​the lower pressing arm gradually decreases from the connecting end to the pressing end.

[0054] Specifically, such as Figure 1 As shown, the transverse clamping mechanism 3 is a two-finger parallel air gripper, and the centering seat is arranged on the two-finger parallel air gripper.

[0055] Specifically, such as Figure 1 As shown, the transverse clamping mechanism 3 is a centering clamp, and the centering seat is arranged on the centering clamp.

[0056] In this embodiment, if Figure 1-2 As shown, the lateral clamping mechanism 3 uses a centering clamp. The process of using the centering clamp involves the operator first placing the workpiece 4 on the centering seat. The operator then simultaneously drives both jaws toward the center until the jaws contact the surface of the workpiece 4. The jaws continue to apply appropriate pressure to securely hold the workpiece 4 in place.

[0057] In some embodiments, the transverse clamping mechanism 3 may also employ a two-finger parallel air gripper. These two-finger parallel air grippers, powered by compressed air, provide rapid clamping. Centering clamps and two-finger parallel air grippers are currently available and will not be described in detail in this embodiment.

[0058] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
