Description

Technical Field

[0001] The present application relates to the technical field of workbench manufacturing, and in particular to a workbench processing and positioning device. Background Art

[0002] In the production and manufacturing process of various industries, workbenches are used to process parts, such as stamping workbenches, drilling workbenches, cleaning workbenches, etc.

[0003] In the prior art, workbenches with different functions have different tabletop structures. For example, the tabletop of a stamping workbench is flat and thick, the tabletop of a drilling workbench is provided with many small holes for removing dust, and the tabletop of a cleaning workbench has many grooves or drainage holes for drainage, etc., and the bottoms of the tabletops of these workbenches are also provided with support frames of different structures to meet different processing requirements. When manufacturing workbenches, since the tabletops of these workbenches have a variety of holes and grooves, if the tabletops of the workbenches are produced by an integrated molding method, the mold will be more complicated and expensive. Therefore, for small batches of workbenches, when producing the tabletops of the workbenches, a complete tabletop is usually produced first, and then slots and holes are drilled on the complete tabletop.

[0004] When slotting and drilling holes in the workbench table top, it is necessary to use a positioning device to fix the table top. Since the locations where slotting or drilling is required are different, the locations that need to be positioned are also different when slotting and drilling holes in different locations. For example, when positioning the left side of the table top, it is necessary to perform additional compression on the left side of the table top based on the basic positioning to prevent the left side of the table top from vibrating or sliding during slotting and drilling, resulting in large errors in the processed slots and holes and being unqualified. Existing table top positioning devices usually have one or more rows of cylinders on a support frame. Where compression is required, the cylinder is controlled to compress the table top. This structure requires the installation of multiple cylinders, which is costly, and multiple cylinders need to be routed separately, causing the entire device to look redundant and complicated. In addition, the position of the cylinder usually cannot be moved, and the adaptability to different table tops is poor.

[0005] Therefore, it is necessary for the inventor to design a new workbench processing positioning device to overcome the above problems. Summary of the invention

[0006] The main purpose of the present application is to provide a workbench processing positioning device to solve the problems of high cost, complex structure and poor adaptability of the positioning device of the workbench table panel in the related art.

[0007] To achieve the above object, the present application provides a workbench processing positioning device, including a support frame, a limiting frame for positioning the table top panel is fixedly connected to the support frame, and a plurality of pressing components are slidably arranged on the limiting frame along the extending direction of the edge of the table top panel, and the output end of at least one pressing component presses on the table top panel.

[0008] Preferably, the pressing component includes a mounting plate and a plurality of cylinders, the mounting plate is slidably connected to the limiting frame, and the cylinders are fixedly installed at the bottom of the mounting plate.

[0009] Preferably, a positioning plate is fixedly arranged at the top of the limiting frame, and the mounting plate is slidably arranged at the bottom of the positioning plate.

[0010] Preferably, a sliding plate is slidably arranged on the top of the mounting plate, and a connecting component is fixedly arranged between the sliding plate and the mounting plate.

[0011] Preferably, the connecting component includes a through groove and a plurality of screw rods, the through groove is opened on the positioning plate, and the screw rods penetrate through the sliding plate and the through groove and are threadedly connected to the mounting plate.

[0012] Preferably, there are two screw rods, and the two screw rods are arranged along the sliding direction of the mounting plate.

[0013] Preferably, at least two mounting grooves are opened at the bottom of the sliding plate, and a roller is rotatably arranged in the mounting groove, and the outer wall of the roller contacts the upper surface of the positioning plate.

[0014] Preferably, both the limiting frame and the positioning plate are in a U shape, and the width of the positioning plate is greater than the width of the limiting frame.

[0015] Preferably, each pressing component includes two cylinders, and the two cylinders are arranged along the moving direction of the mounting plate.

[0016] Preferably, a through port for the cylinders to route wires is opened on the limiting frame.

[0017] A workbench processing positioning device provided by the present utility model, compared with the prior art, has the following beneficial effects:

[0018] By slidably arranging the pressing components on the limiting frame, when slotting and drilling at different positions, it is only necessary to move the pressing components to the vicinity of the target position. Therefore, the number of cylinders required for this device is small, and the number of cables during wire routing is also small, which is convenient for sorting and storage, and the position of the cylinders can be adjusted steplessly, and the adaptability to different table top panels is relatively high.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0026] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described here.

For example, the term "upper" may also be used to represent a certain attachment relationship or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in this application can be understood according to the specific circumstances.

[0029] In addition, the meaning of the term "plurality" should be two or more.

[0030] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will refer to the drawings and combine the embodiments to detail this application.

[0031] As Figures 1 to 4 shown, a workbench processing positioning device includes a support frame 1. A limit frame 2 for positioning a table board 12 is fixedly connected to the support frame 1. A plurality of pressing components are slidably arranged on the limit frame 2 along the extending direction of the edge of the table board 12, and the output end of at least one pressing component presses on the table board 12; both the limit frame 2 and the positioning plate 5 are in a U shape; the pressing component includes a mounting plate 3 and a plurality of air cylinders 4. The mounting plate 3 is slidably connected to the limit frame 2, and the air cylinders 4 are fixedly installed at the bottom of the mounting plate 3; during operation, for a rectangular table board 12, the structural shape of the limit frame 2 being in a U shape is more appropriate, so that at least two sides of the table board 12 can be abutted against the limit frame 2 to realize the limitation of the table board 12. After the edge of the table board 12 abuts against the limit frame 2, when it is necessary to drill and groove a certain position, the pressing component is slidably adjusted to the vicinity of this position and the air cylinder 4 is pressed on the table board 12. To ensure that the table board 12 does not vibrate or move during processing, at least one pressing component should press the table board 12.

[0032] A positioning plate 5 is fixedly arranged at the top of the limiting frame 2, and the mounting plate 3 is slidably arranged at the bottom of the positioning plate 5; a sliding plate 6 is slidably arranged on the top of the mounting plate 3, and a connecting component is fixedly arranged between the sliding plate 6 and the mounting plate 3; the connecting component includes a through groove 7 and a plurality of screw rods 8, the through groove 7 is opened on the positioning plate 5, and the screw rod 8 passes through the sliding plate 6 and the through groove 7 and is threadedly connected with the mounting plate 3; during operation, when it is necessary to move the position of the mounting plate 3, since the mounting plate 3 is located below the positioning plate 5, it is inconvenient for the user to operate. Therefore, the sliding plate 6 connected to the screw rod 8 can be slid to drive the mounting plate 3 to move, so that the cylinder 4 reaches a suitable position. During disassembly, it can be disassembled by unscrewing the bolts. It should be noted that when the cylinder 4 is in use, the output end of the cylinder 4 (i.e., the lower end of the cylinder 4) is pressed against the table top plate 12, and the mounting plate 3 (i.e., the upper end of the cylinder 4) will also abut against the bottom of the positioning plate 5. In the case where both ends are abutted tightly, the frictional resistance is large, and it is difficult for the mounting plate 3 to slide. Therefore, the cylinder 4 can be stably pressed against the table top plate 12.

[0033] There are two screw rods 8, and the two screw rods 8 are arranged along the sliding direction of the mounting plate 3; during operation, if there is only one screw rod 8, the sliding plate 6 may slide relative to the screw rod 8, which is not convenient for the user to use.

[0034] At least two mounting grooves 9 are opened at the bottom of the sliding plate 6, and a roller 10 is rotatably arranged in the mounting groove 9, and the outer wall of the roller 10 is in contact with the upper surface of the positioning plate 5; during operation, when the sliding plate 6 is slid, since the sliding plate 6 and the mounting plate 3 are connected by the screw rod 8, if the bottom of the sliding plate 6 is directly in contact with the positioning plate 5, the frictional force may be large, which makes the threaded connection between the screw rod 8 and the mounting plate 3 unable to be tightened. And the setting of the roller 10 makes the rolling friction between it and the positioning plate 5 during movement, and the frictional force is small. Therefore, the screw rod 8 can be tightened, making the connection between the mounting plate 3 and the sliding plate 6 more stable and compact, and not easy to shake.

[0035] Both the limiting frame 2 and the positioning plate 5 are in a U shape, and the width of the positioning plate 5 is greater than the width of the limiting frame 2; during operation, the positioning plate 5 extends towards the central part of the support frame 1, and the cylinder 4 is installed inside the limiting frame 2.

[0036] Each pressing component includes two cylinders 4, and the two cylinders 4 are arranged along the moving direction of the mounting plate 3; during operation, the pressing effect of the two cylinders 4 is better and more stable when working.

[0037] A through port 11 for the cylinder 4 to route the wire is opened on the limiting frame 2; during operation, the wire of the cylinder 4 is routed from the through port 11, so that the wire of the cylinder 4 is convenient to organize and store.

[0038] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
