Description

Technical Field

[0001] This utility model relates to the field of tooling fixtures, and in particular to a one-outlet, two-vacuum suction tooling fixture device. Background Technology

[0002] Tooling fixtures are devices used to fix workpieces during machining and assembly. They can be divided into mechanical fixtures and vacuum fixtures according to different clamping principles. Vacuum fixtures mainly use negative pressure to attract and fix the workpiece, which makes it less likely to damage the workpiece surface.

[0003] In the existing technology, common vacuum clamps mainly consist of a set of negative pressure devices and multiple sets of connecting pipes. The suction cups installed at the ends of the connecting pipes can be used to attract the workpiece. However, such a set of pipes can only clamp one set of workpieces at a time, resulting in low efficiency. Therefore, a one-outlet-two-vacuum suction tooling clamping device is proposed to solve the above problems. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a one-outlet two-vacuum suction tooling fixture device, which aims to improve the problem in the prior art that "a set of pipe ends can only attract a single set of tools, resulting in low processing efficiency during use".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a one-outlet-two-vacuum suction tooling fixture device, comprising a base plate, a column mounted on the upper surface of the base plate, a top plate mounted on the upper surface of the column, a flow divider plate mounted on the lower surface of the top plate, the flow divider plate being configured as a rectangular plate with a recessed upper surface, an air inlet hole being provided through the surface of the flow divider plate, an air suction groove being provided on the upper surface of the top plate, a storage groove being provided around the upper surface of the top plate near the air suction groove, and a fixing component being provided on the upper surface of the base plate.

[0006] As a further description of the above technical solution: The inner wall of the storage slot is provided with a boss, and the upper surface of the boss is provided with a diversion groove.

[0007] As a further description of the above technical solution: The diversion channel is provided in multiple sets, and the multiple sets of diversion channels are evenly arranged in a crisscross pattern on the upper surface of the boss.

[0008] As a further description of the above technical solution: The inner wall of the storage slot is provided with a first protruding ring and a second protruding ring from the inside to the outside near the protrusion, and the height of the first protruding ring is lower than the height of the second protruding ring.

[0009] As a further description of the above technical solution: A sealing ring is inserted into the upper surface of the diverter plate.

[0010] As a further description of the above technical solution: The fixing component includes a fixing sleeve, which is fixedly connected to the upper surface of the base plate, and the fixing sleeve is configured in a C-shape.

[0011] As a further description of the above technical solution: A pressure plate is slidably connected to the inner wall of the fixed sleeve.

[0012] As a further description of the above technical solution: The upper surface of the fixing sleeve is threaded with a compression bolt.

[0013] This utility model has the following beneficial effects: 1. In this utility model, by setting a flow divider, the negative pressure pipe can be directly connected to the air inlet of the flow divider during processing. In this way, the negative pressure inside the pipe can be transferred to two sets of storage slots at the same time through the air suction slot, so that two sets of workpieces can be fixed at the same time, which is more convenient to use.

[0014] 2. In this utility model, the space inside the storage tank is divided by setting a boss and a diversion groove, so that the negative pressure can be evenly transmitted to various positions in the storage tank, which can improve the stability of the suction. At the same time, the first convex ring and the second convex ring can simultaneously meet the fixing of workpieces of two different sizes, and the overall device has good flexibility.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1 , Figure 2 and Figure 6 This utility model provides an embodiment of a one-outlet, two-vacuum suction fixture device, including a base plate 1 for supporting the overall device. A column 2 for supporting a top plate 4 is mounted on the upper surface of the base plate 1. The top plate 4 is mounted on the upper surface of the column 2. By supporting the top plate 4 with the column 2, a gap can be left between the top plate 4 and the base plate 1 to accommodate a suction pipe. A diverter plate 3 for connecting the suction pipe is mounted on the lower surface of the top plate 4. The diverter plate 3 is a rectangular plate with a recessed upper surface. An air inlet 31 for connecting the suction pipe is provided through the surface of the diverter plate 3. The upper surface of the top plate 3 is closely attached to the lower surface of the top plate 4. When the suction pipe is connected to the air inlet 31, the suction pipe can force a negative pressure at this position by sucking out the air between the diverter plate 3 and the top plate 4. The upper surface of the top plate 4 is provided with a suction groove 41 for air to pass through. The upper surface of the top plate 4 is provided with a storage groove 42 for placing workpieces around the suction groove 41. When a negative pressure is formed on the upper surface of the diverter plate 3, the negative pressure will be transmitted to the storage groove 42 through the suction groove 41, so that the workpiece can be adsorbed inside the storage groove 42. The upper surface of the bottom plate 1 is provided with a fixing component 5.

[0019] Reference Figures 2-4The inner wall of the storage groove 42 is provided with a boss 421 to support the workpiece. The boss 421 can lift the workpiece, thus preventing the workpiece from directly contacting the bottom surface of the storage groove 42. The upper surface of the boss 421 is provided with a diversion groove 422 for air to pass through. Multiple diversion grooves 422 are provided, and the multiple diversion grooves 422 are evenly arranged in a crisscross pattern on the upper surface of the boss 421. By setting multiple diversion grooves 422, the air between the storage groove 42 and the workpiece can be guided to be discharged evenly, so that the negative pressure inside the storage groove 42 is equal everywhere, ensuring the stability of adsorption. The inner wall of the storage groove 42 near the outer side of the boss 421 is provided with a first protruding ring 423 and a second protruding ring 424 from the inside to the outside. The height of the first protruding ring 423 is lower than the height of the second protruding ring 424. When the workpiece size is small, the workpiece can be inserted into the first protruding ring 423, and when the workpiece size is large, the workpiece can be inserted into the second protruding ring 424, thus realizing the processing of workpieces of different sizes.

[0020] Reference Figure 1 , Figure 2 and Figure 5 A sealing ring 32 is inserted into the upper surface of the diverter plate 3. By setting the sealing ring 32, the sealing between the diverter plate 3 and the top plate 4 can be further guaranteed, thus preventing air leakage at the connection between the two. The fixing component 5 includes a fixing sleeve 51 for fixing the suction pipe. The fixing sleeve 51 is fixedly connected to the upper surface of the bottom plate 1. The fixing sleeve 51 is C-shaped and made of elastic material. During use, the suction pipe can be directly inserted into the inside of the fixing sleeve 51. A pressure plate 52 for squeezing the suction pipe is slidably connected to the inner wall of the fixing sleeve 51. A squeezing bolt 53 is threaded through and connected to the upper surface of the fixing sleeve 51. By rotating the squeezing bolt 53, the lower end of the squeezing bolt 53 can be moved downward, thus squeezing the pressure plate 52. The pressure plate 52 will move downward and squeeze the suction pipe, thus fixing the suction pipe. This can prevent the vibration generated by instantaneous suction from affecting the connection between the suction pipe and the diverter plate 3.

[0021] Working Principle: By connecting an external negative pressure pipe to the air inlet 31 of the diverter plate 3, after the negative pressure source is activated, the air in the pipe is extracted, forming a negative pressure in the sealed space between the diverter plate 3 and the top plate 4. The sealing ring 32 on the upper surface of the diverter plate 3 will tightly fit against the lower surface of the top plate 4 to ensure the sealing of the connection and prevent negative pressure leakage. The negative pressure on the lower surface of the top plate 4 is conducted upward through its internal suction groove 41 and finally acts on the placement groove 42 on the upper surface of the top plate 4. At this time, the air between the placement groove 42 and the workpiece is gradually extracted, forming a pressure difference, thereby adsorbing and fixing the workpiece in the placement groove 42. The protrusions 421 on the inner wall of the placement groove 42 can lift the workpiece to prevent it from directly contacting the bottom of the groove and ensure air circulation. The multi-component diverter grooves 422 on the upper surface of the protrusions 421 are crisscrossed to guide the air to be discharged evenly, so that the negative pressure intensity in each area of ​​the placement groove 42 is consistent, improving the adsorption stability and preventing the workpiece from shifting due to uneven force.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
